1 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 Added resolve_cmd_ident field to the SilcClientEntry structure
4 too so that if the entry is for example being resolved so
5 another command may attach to the same pending command reply
6 without requiring to resolve the same entry again. Added
7 support for adding multiple pending commands for one
8 command idenfier. Affected files lib/silcclient/command.[ch],
9 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
11 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
13 * Defined that server receives WHOIS command reply for private
14 and secret channels too. Updated protocol specs and the
15 code in server. Affected file silcd/command.c.
17 * Defined <channel user mode list> argument to WHOIS command
18 reply for returning user modes on the channels. The
19 channel list now doesn't include the user mode anymore but the
20 actual channel mode. Updated protocol specs and the code in
21 client and server. Affected files are silcd/command_reply.c,
22 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
23 and lib/silcclient/command_reply.c.
25 * Save the channels list in WHOIS command reply in normal server
26 so that WHOIS always shows joined channels also in normal
27 server and not just on router. Affected file is
28 silcd/command_reply.c.
30 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
32 * Defined that server receives USERS command reply for private
33 and secret channels too. Updated protocol specs and the

36 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Changed the UMODE's mode mask argument to be optional. If
39 not provided then the command merely returns the current mode
40 mask to the client. Updated protocol specs and the server.
41 Affected file is silcd/command.c.
43 * Added SILC session detachment/resuming support. It is possible
44 to detach by closing the network connection and then re-connect
45 and resume to the old client session. Added DETACHED user
46 mode that server will set for detached client. Added new
47 packet RESUME_CLIENT which is used to perform the resuming
48 process. Added DETACH command. Updated the protocol specs,
49 core library, client and server. Protocol TODO #22. Very
50 many affected files around the tree.
52 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
54 * Changed the CMODE's mode mask argument to be optional. If
55 not provided then the command merely returns the current mode
56 mask to the client. Updated protocol specs and the server.
57 Affected file is silcd/command.c.
59 * Changed the Killer's Client ID in KILLED notify to be just
60 any ID payload since router server is allowed to kill as well.
61 Updated protocol specs, client libary and server. Affected
62 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
63 and irssi/src/silc/core/client_ops.c.
65 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
67 * Added new user modes ANONYMOUS for special anonymous servers
68 that may set the mode for client, and BLOCK_PRIVMSG which
69 client may set to block incoming private messages unless the
70 Private Message Key flag is set (using private keys to protect
71 private messages). Updated protocol specs and code in client
72 and server and core library. Protocol TODO #23. Affected
73 files are lib/silccore/silcmode.h, silcd/server.[ch],
74 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
75 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
77 * Added new channel user mode BLOCK_MESSAGES which the client
78 may set to itself to tell server not send channel messages.
79 Other packets such as channel key packets are still sent.
80 Protocol TODO #23. Updated the protocol specs, client and
81 server. Affected files are lib/silccore/silcmode.h,
82 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
83 lib/silcutil/silcutil.c, silcd/command.c, and
86 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
88 * Redefined the Status Payload to include now two 8 bit fields,
89 instead of one 16 bit field. This now makes it possible to
90 send list of errors. Updated the protocol specs and the code
91 in core library, client library and server. Protocol TODO #1.
92 Affected files are lib/silccore/silccommand.[ch],
93 lib/silcclient/command_reply.[ch], silcd/command.c,
94 silcd/command_reply.c and silcd/packet_receive.[ch].
96 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
98 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
99 must be handled by the application and should tell the application
100 that an error message was already printed, and it should print the
101 config coords (line, filename, ...). Affected files are
102 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
104 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
105 server config parsing code more readable.
107 Fixed a bug in the fetch_logging() config callback.
109 Affected files is silcd/serverconfig.c.
111 * Drop root privileges when started in foreground. Don't drop them
112 if debugging also. Affected file is silcd/silcd.c.

120 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
121 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
123 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Added STATS command to the protocol after all, to return
126 various statistical information about the network. It can
127 be used by clients to retrieve statistical information, and
128 servers may use it to to fetch cell and network wide
129 statistics from router. Updated the protocol specs and
130 implemented it to the server. Protocol TODO #16.
131 Affected files are lib/silccore/silccommand, silcd/command.[ch],
132 silcd/command_reply.[ch].
134 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
136 * The LIST command reply in client libary now adds new channel
137 entry if the returned channel doesn't exist yet in cache,
138 and returns the channel entry to the application in the
139 command_reply client operation. Affected file is
140 lib/silcclient/command_reply.c.
142 * Changed the channel message payload's MAC generation to
143 include the IV in the MAC as well. This way all relevant
144 parts of the channel message payload are authenticated also
145 with the channel message MAC (and not only by packet MAC).
146 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
147 Affected file is lib/silccore/silcchannel.c.
149 * Fixed the SKE to save the remote version, since the
150 silc_ske_parse_version mistakenly checked wrong version,
151 after it replaced the start payload. Affected files are
152 lib/silcske/silcske.[ch].
154 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
157 string utility functions. Added there also new functions
158 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
159 Affected files lib/silcutil/silcstrutil.[ch].
161 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
162 files are lib/silcutil/silcstrutil.[ch].
164 * Defined that the security property fields in SKE SHOULD be
165 UTF-8 encoded, defined that version string MUST be US-ASCII
166 encoded, defined that passphrases sent in connection
167 authentication protocol MUST be UTF-8 encoded. Implemented
168 these to the client and server. Defined also that other
169 passphrases sent in the protocol MUST be UTF-8 encoded.
170 Affected files are lib/silcske/silcske.c,
171 lib/silcclient/protocol.c, silcd/protocol.c,
172 silcd/serverconfig.c, and lib/silccore/silcauth.c.
174 * Changed the silc_client_close_connection interface to not
175 need the SilcSocketConnection which should not be visible
176 to application. Affected files are lib/silcclient/client.c
177 and lib/silcclient/silcclient.h.
179 * Rewrote the text for Private Message Key Payload in the
180 protocol specification. Protocol TODO #11.
182 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Upgraded the protocol version to 1.1, updated protocol specs

195 Protocol TODO #13. Affected files are silcd/command.c,
196 silcd/packet_receive.c, packet_send.[ch],
197 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
198 The killer's client entry is now returned to application in
199 the `notify' client operation.
201 * Fixed the Max Argument fields that had too large value set
202 in the protocol specs. Protocol TODO #14.
204 * Added the LEAVE command reply to return the ID of parted
205 channel. Updated protocol specs and implemented it to the
206 client and server. Protocol TODO #15. Affected files are
207 silcd/command.c, lib/silcclient/command_reply.c. The channel
208 entry is now returned to application in the `command_reply'
211 * Rewrote the version SKE version checking in client libary
212 and in server to use the silc_parse_version_string. Affected
213 files are lib/silcclient/protocol.c, silcd/protocol.c.
215 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
216 commands that was missing it, and updated protocol specs and
217 the server implementation. Protocol TODO #10. The affected
218 file is silcd/command.c.
220 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
221 generic reply to a generic request (REQUEST flag), and
222 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
223 way. A draft-riikonen-silc-flags-payloads-00.txt is written
224 to define the payload for DATA flag. Added the flags to
225 the implementation. Protocol TODO #9. Affected file is
226 lib/silccore/silcchannel.h.
228 Changed the client library to return the message length
229 to application as well in the channel_message and private_message
230 client operations. Affected files are
231 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
232 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
233 and lib/silcclient/client_ops_example.c.
235 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
236 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
237 the channel. Updated protocol specs and impelemented this
238 to client and server. Protocol TODO #6. Affected files are
239 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

242 Added new options m and M to CMODE command in Irssi SILC
243 client to set these modes.
245 * Deprecated all administrative commands from SILC protocol
246 since they are highly implementation specific commands.
247 Updated protocol specs. Moved the old commands in
248 implementations to private range of command types. Affected
249 files are silcd/command.c, lib/silcclient/command.c and
250 lib/silcclient/command_reply.c. Protocol TODO #8.
252 * Fixed a bug in server where sending unknown command crashes
253 the server. Affected file silcd/command.c.
255 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Added SILC_PROTOCOLVERSION macro to check protocol version
258 of a socket connection. The affected file is
259 lib/silcutil/silcsockconn.h.

268 Affected file silcd/protocol.c.
270 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Some client implementations quit network by doing first LEAVE
273 and then immediately SIGNOFF (like Bombyx). We now do check
274 after a short time after LEAVE notify and check whether the
275 client is still valid after LEAVE, and if not we remove it from
276 cache. Affected file is lib/silcclient/client_notify.c.
278 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
280 * Merged version 1.1.4 of zlib. Even if it not currently in use,
281 it's good not to have security holes here.
283 * Fixed a negative refcount situtuation for the config context.
284 Affected file is silcd/serverconfig.c.
286 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
288 * ROBOdoc documented lib/silcutil/silcutil.h.
290 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
292 * Optimized even more the SilcPacketContext structure. Now
293 totally saved 16 bytes of memory per context after optimization.
294 Affected files are lib/silccore/silcpacket.[ch].
296 * Made strict checks for valid SILC IDs. Affected file is
297 lib/silccore/silcid.c.
299 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

304 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
306 * Changed the silc_get_username and silc_get_real_name to
307 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
309 * Fixed the Irssi SILC Client to use the silc_get_username and
310 silc_get_real_name insted of glib routines since the glib
311 routines only corrupt stack. Fixes the Irssi SILC to work in
312 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
314 * Fixed the Irssi to not use g_get_home_dir since it crashes
315 or returns garbage on cygwin and corrupts stack. Added function
316 get_home_dir to Irssi routines. Affected files are
317 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
319 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
321 * Made some structure optimizations. SFTP memory FS MemFSEntry
322 entry structure. Optimized SilcTask structure. Optimized
323 SilcPacketContext structure.
325 Affected files lib/silcsftp/sftp_fs_memory.c,
326 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
328 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
330 * And yet again reverted back the config thing since Johnny
331 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
334 * Fixed memory leaks from config object. Affected files are
335 silcd/serverconfig.[ch].
337 * Added support for adding new connections to the server in rehash.
338 After rehash they take effect.
340 Added support for changing the maximum allowed connections in
341 rehash. The number can grow but going smaller is not supported.
343 Added function silc_server_num_sockets_by_remote to the
344 silcd/server_util.[ch].
346 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
348 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
350 * Added preliminary checking during config parsing for a valid
351 public/private key and removed further checks in the code.
352 Affected files are silcd/serverconfig.[ch], server.c.
354 * Moved functions silc_server_drop() and silc_server_daemonise()
355 from server.c to silcd.c since they are stricly related to
356 the application activity.
358 * Reverted a small part of the automatic ref/unref since
359 it caused a double unref in some situations. Affected
360 files are silcd/silcd.[ch], server.c, serverconfig.c.
362 * Added some .cvsignore files in the lib directory.
364 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
366 * Fixed silc_net_gethostbyaddr to correctly resolve by
367 address. Affected file lib/silcutil/silcnet.c.
369 * Fixed the notify relaying to client. The HMAC to be used
370 with relayed packets ws wrong and caused decryption failure
371 at the client end. Affected file is silcd/packet_receive.c.
373 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
375 * Created new branch silc_protocol_1_0_branch.
377 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
379 * Changed the silc_server_config_* routines to be SilcServer
380 independent. They are now officially application specific code
381 and not part of generic server implementation. Affected files
382 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
384 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
386 * Added automatic referencing of config context in the
387 silc_server_config_alloc, and automatic unreferencing in the
388 silc_server_config_destroy. Affected files are
389 silcd/serverconfig.[ch], silcd/silcd.c.
391 * Fixed the silc_log_quick handling in the logging routines.
392 It didn't log quickly when it was TRUE. Affected file is
393 lib/silcutil/silclog.c. Also the flush delay was set even
394 if it was 0 in config file. Affected file is
395 silcd/serverconfig.c.
397 * Added support for changing key pair of the server in rehash.
398 Affected file silcd/server.c.
400 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
402 * Fixed the TOPIC_SET notify to not cras. It changed the topic
403 too early, before getting the channel entry. Affected file
404 is silcd/packet_receive.c.
406 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
408 * Added functions silc_server_config_[ref/unref], these are used
409 to prevent that the config object is destroyed.
411 No longer directly affect global variables silc_log_quick and
412 silc_log_delay, they are first cached inside the config object
413 and then applied with silc_server_config_setlogfiles().
415 silc_server_config_set_defaults() is now internal to
416 serverconfig.c, there are no reasons to show this internal stuff
419 Affected files are silcd/serverconfig.[ch].
421 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
422 fprintf's to stderr, since some code may be executed again after
423 the server went into the background. Affected files are
426 * Added rehash support. Added function silc_server_rehash() that
427 will perform all the basic tasks of the rehashing procedure.
429 * Added command line option `-x, --hexdump'. This will enable the
430 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
431 The option `--hexdump' implies `--debug'.
433 * Fixed a bad bug in the logging APIs (silcutil library) where
434 the application would crash after calling silc_log_reset_all().
436 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
438 * Fixed the KICKED notify handling in client library to
439 correctly remove the channel and all entries from the
440 channel when I was kicked. This bug crashed the client.
442 Fixed yet another but in KICKED notify handling to remove
443 the kicked client correctly from the channel.
445 Affected file is lib/silcclient/client_notify.c.
447 * Fixed a minor bug in looking up correct client entry
448 in KICKED notify in server. Affected file is
449 silcd/packet_receive.c.
451 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
452 sources correctly to distribution. Fixes --with-gmp option.
454 * Removed the manual rehashing from ID Cache, and changed it
455 to use the SILC Hash Table's auto rehash feature. Affected
456 file is lib/silccore/silcidcache.c.
458 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
460 * Fixed a bug in the silc_client_nickname_format function that
461 handles the multiple same nickname formatting. Two clients
462 with same nickname caused problems after the first one left
463 and rejoined. It didn't format the nickname correctly.
464 Affected file is lib/silcclient/idlist.c.
466 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Don't change the topic if olod topic is same as new one.
469 Affected file is silcd/packet_receive.c.
471 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
473 * Added cross-reference support to the SILC Documentation
474 generator. All types across all HTML files are now cross-
475 referenced. Affected files util/robodoc/generator.c and
476 scripts/silcdoc/silcdoc.
478 * Added file lib/silcutil/silctypes.h to include all the
479 arithmetic type definitions and some macros. Removed
480 includes/bitmove.h and moved macros to silctypes.h.
482 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

489 now returns the type of the ID to the sent pointer. Affected
490 file is lib/silccore/silcid.[ch].
492 * Added check for CMODE_CHANGE notify type that mode change is
493 allowed by the sender. Affected file silcd/packet_receive.c.
495 * Added check for CUMODE_CHANGE notify type that mode change is
496 allowed by the sender. Affected file silcd/packet_receive.c.
497 Added the ID type as CUMODE_CHANGE notify type as argument
498 to the `notify' client operation. Affected files are
499 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
501 * Added function silc_client_add_server to the client library.

503 received unknown entity in notify packet. Affected files are
504 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
506 * Added function silc_command_get_status to return the command
507 status from the command reply's argument payload. Affected files
508 are lib/silccore/silccommand.[ch].
510 * Added check for KICKED notify type that the kicking is
511 allowed by the client. Affected file silcd/packet_receive.c.
513 * Created function silc_get_input which can be used to get input
514 (echo on or off) from user on command line. Affected files are
515 lib/silcutil/silcutil.[ch].
517 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * Optimized silc_server_packet_relay_to_channel function.
520 Added new function silc_channel_message_payload_encrypt which
521 can be called directly if channel message payload needs to
522 be encrypted and is already encoded (no need to call _encode
523 function). Packet relaying is now done by router without any
524 extra memory allocations. Affected files are
525 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
528 * Fixed the INVITE notify handling. It took wrong arguments
529 as invite list and invite delete. Affected file is
530 silcd/packet_receive.c.
532 * Added check for TOPIC_SET notify type that the topic change is
533 allowed by the client. Affected file silcd/packet_receive.c.
535 * Added check for INVITE notify type that inviting is allowed by
536 the client. Affected file silcd/packet_receive.c.
538 * Changed the silc_server_client_on_channel to return the
539 SilcChannelClientEntry as well. Moved the function
540 silc_server_check_cmode_rights to server_util.[ch].
541 Affected files are silcd/server_util.[ch], silcd/command.c.
543 * Added function silc_server_check_umode_rights to check whether
544 changing client's user mode is allowed. Added check for
545 UMODE_CHANGE notify type that the umode change is allowed
546 by the client. Affected files are silcd/server_util.[ch],
547 silcd/packet_receive.c and silcd/command.c.
549 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
552 ID length. It ignored that ID can be IPv6 based as well.
553 Affected file lib/silccore/silcpacket.h.
555 * Fixed the silc_id_id2str and silc_id_str2id to take the
556 IPv6 address offset's into consideration. Affecte file is
557 lib/silccore/silcid.c.
559 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
561 * Fixed the internal Unix scheduler functions to check for
562 NULL context they may receive. The affected file is
563 lib/silcutil/unix/silcunixschedule.c.
565 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
567 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
568 can specify different directory with --home command line
569 parameter. Affected files irssi/src/silc/core/client_ops.c,
572 * SILC-specific commands aren't now executed if the active server
573 isn't of SILC-type, so there won't be problems with having
574 IRC and SILC protocol support in same client. Affected files
575 irssi/src/silc/core/silc-channels.c, silc-servers.c,
578 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
580 * Improved the signal support in SILC Schedule. Added new
581 function silc_schedule_signal_call which is used by application
582 to mark a signal to be called. It is now safe to perform
583 any kind of tasks in signal callbacks since it is guaranteed
584 that the application specified signal callback is called
585 after the signal is over. Affected files are
586 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
588 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
590 * Added `name' field to SilcChannelPrivateKey to represent
591 application given name for the key. Moved also the context from
592 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
593 Added the `name' argument also to the function
594 silc_client_add_channel_private_key.
596 Added function silc_client_current_channel_private_key to set the
597 current channel private key in use.
599 Added "change" command to KEY command which can be used to change
600 the current channel private key. Bound the command also to
603 Also affected files lib/silcclient/client_channel.c,
604 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
606 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
608 * Added silc_rng_get_byte_fast function in to the
609 lib/silccrypt/silcrng.[ch].
611 * Changed the interface of silc_packet_assemble and the
612 silc_packet_send_prepare. If silc_packet_assmble is now
613 called the application does not call silc_packet_send_prepare
614 because the library will call it automatically. These
615 interfaces now also return a reference to the outgoing buffer
616 which includes the assembled packet, which the application can
617 use to encrypt the packet.
619 Affected files are lib/silccore/silcpacket.[ch],
620 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
621 silcd/packet_send.c, server_backup.c and packet_receive.c.
623 * Fixed a packet sending bug on very high load, where outgoing
624 packet queue wasn't handled correctly and packets got corrupted.
625 Affected files are lib/silcutil/*/silc*sockconn.c,
626 lib/silcclient/client.c and silcd/server.c.
628 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Added macro SILC_PACKET_DATALEN which can be used during
631 packet assembling to check whether the data to be added to
632 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
633 len is truncated until it fits it.
635 Added checks for maximum length of channel message payload and
636 private message payload also.
638 Added checks for maximum packet length in server and in
641 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
642 lib/silcclient/client.c, lib/silccore/silcchannel.c and
643 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
644 lib/silcclient/client_prvmsg.c.
646 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
648 * Added silc_server_packet_queue_purge call to the
649 silc_server_disconnect_remote to assure that all data in the
650 queue before disconnecting is sent to the network. Affected
653 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Added the deleting of server's own ID cache entry to the
656 silc_server_free function. Free also everything else that
657 has been allocated in silc_server_init. The affected file
660 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
662 * Added functions silc_parse_version_string, silc_version_to_num,
663 and silc_ske_parse_version to parse SILC protocol style version
664 strings. Affected files lib/silcutil/silcutil.[ch] and
665 lib/silcske/silcske.[ch].
667 * Added new configuration params: version_protocol, version_software
668 and version_software_vendor to specify what version the remote
669 host must at least be to be able to connect to server. The vendor
670 string can be regex matched too. Added new function
671 silc_server_connection_allowed to check maximum number of allowed
672 connections, and allowed versions for incoming connections.
673 Affected files are silcd/server.c, server_util.[ch] and
676 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Added preliminary support for signals in scheduler. The
679 signals we care about are now blocked always when the scheduler
680 is locked. This way we can synchronise the use of signal with
681 scheduler. It is guaranteed that when signal occurs the scheduler
682 is not locked, and thus new tasks can be safely added to the
685 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
686 to silc_schedule_internal_init and silc_schedule_internal_uninit.
687 Added new platform specific routines
688 silc_schedule_internal_signals_[un]block and
689 silc_schedule_internal_signal_[un]register.
691 Added new functions to SILC Schedule API:
692 silc_schedule_signal_[un]register. Each signal that application
693 is going to use should be registered to the scheduler.
695 Affected files are lib/silcutil/silcschedule.[ch],
696 lib/silcutil/*/silc*schedule.c.
698 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Check for unauthenticated client and server in the
701 silc_server_new_client and silc_server_new_server functions.
702 Affected file silcd/packet_receive.c.
704 * Added function silc_string_is_ascii to check whether given
705 string is 7-bit ASCII string. Affected files are
706 lib/silcutil/silcutil.[ch].
708 * Added function silc_id_is_valid_server_id into the
709 silcd/serverid.c and added checking for valid Server ID's in
710 silc_server_new_server. The Server ID must always be based
711 on the server's public IP address.
713 * Added logging of DISCONNECT packet message in the server.
714 Affected file silcd/server.c.
716 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
718 * Changed all library interfaces that use Global RNG to also
719 accept SilcRng as argument. Affected files are
720 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
721 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
722 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
723 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
726 * Added function silc_pkcs_generate_key to the
727 lib/silccrypt/silcpkcs.[ch] for applications so that they
728 don't need to do pkcs->pkcs->init calls anymore.
730 * Remove SilcSocketConnection from the SFTP API since it really
731 wasn't needed there. The application has the information
732 saved in its contexts anyway and the SFTP layer doesn't need
733 know about it. Affected files lib/silcsft/silcsftp.h and
734 lib/silcsftp/sftp_[server/client].c.
736 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
737 The SilcSimContext is not SilcSim.
739 * Fixed possible buffer overflows in silc_id_render in the
740 lib/silcutil/silcutil.c.
742 * On EPOC the global crypto module lists are not used at all
743 in the crypto library. Added support for using the constant
744 algorithm list on EPOC. Affected files are
745 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
748 * Fixed the handling of third parameter of KICKED notify, since
749 it was mistakenly updated to SILC Protocol 1.0 even though it
750 is to be included in 1.1. Since it is not in 1.0 it is not
751 mandatory, and this fix now handles it only if it is provided,
752 and it is not error if it is not provided. Affected file
753 lib/silcclient/client_notify.c.
755 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
757 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
758 client. Affected file irssi/src/silc/core/client_ops.c.
760 * Merged with Irssi 0.8.4 from irssi.org CVS.
762 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
764 * Check for valid socket connection in client entries before
765 sending any messages. Fixes a crash, but doesn't fix some
766 other underlaying bug that is lurking there. Affected
767 file silcd/packet_send.c.
769 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
771 * $usermode, $cumode and $cumode_space expandos shouldn't do
772 anything with non-SILC server records. Affected file
773 irssi/src/silc/core/silc-expandos.c
775 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
777 * Fixed the silc_net_check_[host/local]_by_sock to support
778 IPv6 bound sockets as well. Now they can return IPv6 addresses
779 as well. Affected file lib/silcutil/silcnet.c.
781 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
782 Affected lib/silcutil/unix/silcunixnet.c.
784 * Fixed ID rendering (at least on some platforms, not NetBSD)
785 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
787 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
789 * Added silc_hash_public_key and silc_hash_public_key_compare
790 functions to be used with SilcHashTable. They can be used to
791 hash public keys and compare public keys in hash table. Affected
792 file lib/silcutil/silcutil.[ch].
794 * Added support for specifying multiple public keys for Client
795 connection section in server configuration file. This makes it
796 possible to accept multiple public keys from same host, or to
797 make a section that accepts any incoming host, and have the
798 accepted public keys listed in the section.
800 Added functions silc_sever_[find/get]_public_key, added the
801 support for this actually to all connection sections but only
802 the Client section is currently allowed to specify multiple
805 Affected files are silcd/server.c, server_internal.h,
806 command.c, protocol.c, server_util.[ch], packet_receive.c.
808 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Merged Irssi 0.8.2 from irssi.org CVS.
812 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
814 * If silc_debug is TRUE, also output standard logging messages
815 to stderr with the debug output.
817 Made silc_log_reset_all() flushing all channels before returning.
818 Also fixed some documentation typos.
820 Affected files are lib/silcutil/silclog.[ch].
822 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
824 * Fixed the server to check correctly the amount of connections
825 from single host, by checking also the type of the connection.
826 Fixed also the comparison of number of connections and number
827 of allowed connections. Affected files are silcd/server.c,
830 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
832 * Fixed the USERS command reply to save the user's mode on the
833 channel as well. Fixed JOIN command reply to check whether a
834 client is on channel already and not join it twice. Affected
835 file lib/silcclient/command_reply.c.
837 * Added new file silc-expandos.c into irssi/silc/core/ to return
838 various stuff for various signal for the statusbar etc. updating.
839 Now Irssi SILC client prints channel user modes etc. on the
842 * The user mode (like server/router operator changes) is now shown
843 on the Irssi SILC client's statusbar. The affected files are
844 irssi/src/silc/core/client_ops.c, silc-expandos.c.
846 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
848 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
849 to SILC_SCHEDULE_[UN]LOCK macros.
851 * Added more error printing to logs in server code. Affected
852 files silcd/server.c and silcd/protocol.c.
854 * Fixed -S option parsing in Irssi SILC Client. Affected file
855 irssi/src/silc/core/silc-core.c.
857 * Added silc_buffer_alloc_size function. Affected file is
858 lib/silcutil/silcbuffer.h.
860 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
862 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
863 constants. Affected files in
864 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
867 * Changed the internal SFTP Memory FS table to const. Affected
868 file lib/silcsftp/sftp_fs_memory.c.
870 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
872 * Fixed the buffer formatting and unformatting routines to
873 check the size of 64 bits types with sizeof(). Affected
874 file is lib/silcutil/silcbuffmt.c.
876 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
878 * Removed 0.6.x backwards support.
880 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
882 * Changed all integer type names:
883 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
884 to avoid collisions with other libraries using same type names
887 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
889 * Added `prefer_ipv6' argument to the functions
890 silc_net_gethostbyname[_async]. If it is TRUE it will return
891 IPv6 address over IPv4. If FALSE IPv4 address is returned
892 even if IPv6 address was found. Affected files
893 lib/silcutil/silcnet.[ch].
895 * Added support silc_net_create_connection[_async] to fallback
896 to IPv4 address if IPv6 address could not be used (like if
897 it doesn't work on a specific system). Affected file in
898 lib/silcutil/unix/silcunixnet.c.
900 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
902 * Added silc_schedule_reinit function to do the enlarging
903 of the max tasks handling capabilities of the scheduler.
904 Affected files lib/silcutil/silcschedule.[ch].
906 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Added automatic extern "C" { ... } for C++ compilers so the
909 application does not need to define them. Affected file
910 includes/silcincludes.h.
912 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
913 old name went against naming convention. Applications now
914 include "silcclient.h" instead of "clientlibincludes.h".
915 Removed includes/clientlibincludes.h, it is redundant now.
917 * Renamed includes/version.h to silcversion.h.
919 * Added really preliminary support for OS/2 into the util
920 library. Only thread & mutex API is implemented, others
921 are still to be implemented. Created the lib/silcutil/os2/
922 directory. Created also file includes/silcos2.h.
924 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Added preliminary BeOS support into the util library.
927 Created lib/silcutil/beos/, and implemented all the needed
928 functions to support SILC on BeOS. Created also file
931 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
933 * Added proper initializations to silc's irssi code, so it's
934 now possible to load it as module. Affected files
935 irssi/src/silc/core/silc-core.c,
936 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
938 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
940 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
943 * Fixed the silcdoc document generator to correct generate
944 docs from all kinds of filenames. Affected files are
945 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
947 * ROBOdoc documented lib/silcutil/silcmemory.h.
948 Added also new function silc_memdup.
950 * Removed lib/silcutil/silcbufutil.h and moved those routines
951 to the lib/silcutil/silcbuffer.h.
953 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
955 * Added `user_count' to the SilcChannelEntry which now tells the
956 number of users on the channel. The user count is now saved
957 in normal server of global channels as well. Affected files
958 silcd/server.c, idlist.h, packet_receive.c and command.c.
960 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
961 include file utility functions.
963 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
964 instead of calling directly OS routines.
966 * Fixed NICK change printing in Irssi SILC Client. Fixed
967 KICKED notify printing in Irssi SILC Client. Affected file
968 irssi/src/silc/core/client_ops.c.
970 * Fixed a NICK change bug in client library, to not recreate the
971 client_entry->channels hash table everytime nick is changed.
972 Affected file lib/silcclient/client.c.
974 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
976 * ROBOdoc documented the lib/silcske/silcske.h, and improved
977 the SKE interface a bit.
979 * Fixed padding problem in PKCS#1. The padding was not actually
980 random since the random number generator was used incorrectly.
981 This security bug affects only when encrypting with PKCS#1, and
982 it is not currently used at all in SILC. SILC only use signing
983 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
985 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * Rewrote the notify handling in Irssi SILC client to not call
988 the events as signals. Fixes problems with Perl support.
989 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
991 * Send the auto-nicking NICK command in client library with
992 little timeout after connecting. The affected file is
993 lib/silcclient/client.c.
995 * Added following new config file settings:
996 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
997 key_exchange_timeout, conn_auth_timeout, connections_max,
1000 Implemented all the new config settings handling in the server.
1002 Optimized the use of SKE Mutual flag usage. Use it only
1003 if connection authentication protocol is not based in public
1006 Renamed all SilcServerConfigSection* to SilcServerConfig*
1007 to have a bit shorter names.
1009 Affected files silcd/serverconfig.[ch], server.[ch], and
1012 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1014 * Cleaned up the listening sockets code, preparing for the rehash
1015 support. Affected file is silcd/server.c.
1017 * Fixed some output messages. Affected files are silcd/silcd.c,
1020 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Create lib/doc/silcrng_intro.html document as introduction
1023 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1025 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1027 * Fixes to the silcd config template. Affected file is
1028 doc/example_silcd.conf.in.
1030 * Removed type casts from silc_calloc(), conforming to the
1031 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1033 * Removed param_name member from client, server, and router
1034 section structs, now identifying the param directly.
1036 Added CONFIG_FREE_AUTH macro in config file parsing.
1038 Affected files are silcd/serverconfig.[ch].
1040 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1042 * Fixed command line parameter handling. All SILC initialization
1043 is now done in silc_core_init() which also fixes autoconnecting

1047 irssi/src/fe-text/silc.c.
1049 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1051 * Added new configuration options and blocks:
1052 keepalive_secs, reconnect_count, reconnect_interval,
1053 reconnect_interval_max, reconnect_keep_trying and
1054 require_reverser_lookup. Added ConnectionParam block, and
1055 implemented the connection parameters when connecting as
1056 initiator and when accepting connections as responder.
1058 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1059 whether given configuration value has been given already.
1061 Affected files silcd/serverconfig.[c], server.[c].
1063 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1064 algorithm parts and created new file silcalgs.conf, that
1065 is now included from the example_silcd.conf.in.
1067 * Optimized the silc_server_connect_to_router_second to take
1068 the connection configuration object from the SilcServerConnection
1069 object instead of finding it during the connecting phase.
1070 Added the configuration object to SilcServerConnection struct.
1071 Affected files silcd/server_internal.h, server.c.
1073 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1075 * Add the client on channel after it was resolved at the
1076 channel message receiving, and it was not already on the
1077 channel. Affected file lib/silcclient/client_channel.c.
1079 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1081 * Fixed the public key authentication to allocate always the

1087 * Unified the serverconfig.[ch]'s helper function interface.
1088 Affected file silcd/serverconfig.[ch].
1090 * Removed doc/example_silc.conf.in since it is redundant.
1091 The make install will now install irssi/silc.conf file.
1093 * Added new Passphrase and Publickey authentication methods to
1094 config file, allowing both public key and passphrase based
1095 authentication to be set at the same time.
1097 Added `prefer_passphrase_auth' setting in config file which
1098 can be used to set to prefer passwd auth if both passwd and
1099 public key is set. If not set, public key is preferred.
1100 This has effect only when being initiator (responder will try
1103 Added support for authentication with passphrase and public key
1104 at the same time. The passphrase is tried first always since
1105 it is faster to check.
1107 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1109 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1111 * Merged the new SILC Config library, with the server parsing
1112 support. Read the header file silcconfig.h or the toolkit
1113 documentation for the news. Affected files are

1122 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1124 * The silc_cipher_register, silc_hash_register and
1125 silc_hmac_register now checks if the object to be registered
1126 is registered already. Affected files are
1127 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1129 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1131 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

1135 * Allow zero length channel messages inside the Channel Message
1136 Payload. Affected file lib/silccore/silcchannel.c.
1138 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1139 as header filenames.
1141 * Removed lib/silcclient/README and created HTML file
1142 lib/silcclient/silcclient_using.html, which is now included
1143 as part of Toolkit documentation.
1145 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1147 * Fixed CUMODE_CHANGE notify handling to change the mode of
1148 correct client. Affected file lib/silcclient/client_notify.c.
1150 * Make silc_rng_alloc fail if it cannot allocate the sha1
1151 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1153 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1155 * Fixed the file transfer's key agreement payload to include
1156 zero port also if the hostname is NULL because it could not
1159 Call file transfer monitor callback now also if error occurs
1160 during key agreement protocol.
1162 Changed the silc_client_file_send interface to return the
1163 SilcClientFileError instead of session id. The session ID
1164 is returned into pointer provided as argument.
1166 Check that the file exists locally before sending the
1167 file transfer request at all.
1169 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1171 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1172 error than can occur while key agreement protocol. Affected
1173 file lib/silcclient/silcapi.h.
1175 * Fixed the event_mode CMODE handler to not crash when mode
1176 is changed and +k mode is set in the channel. Affected file

1179 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1180 SILC_LOG_WARNING to give out Warning and not Error. Affected
1181 file lib/silcutil/silclog.c.
1183 * Fixed the channel message payload decryption in the function
1184 silc_channel_message_payload_decrypt to not modify the original
1185 buffer before it is verified that the message decrypted
1186 correctly. Otherwise, next time it is called with correct
1187 channel key it won't encrypt since the payload is corrupted.
1188 Affected file lib/silccore/silcchannel.c.
1190 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1198 Affected file lib/silcutil/silcnet.c.
1200 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1202 * Fixed a bug in hash table internal routine for traversing
1203 the table with foreach callback. The current entry may
1204 become invalid in the callback but it was referenced after
1205 the callback returned.
1207 Do not allow auto rehashing of hash table during the
1208 silc_hash_table_foreach operation, for same reasons as it is
1209 not allowed for SilcHashTableList. Affected files are
1210 lib/silcutil/silchashtable.[ch].
1212 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1215 Win32 DLL. extern's in header files are now declared with
1218 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Fixed private message handling. It used some old code that
1221 caused the client to crash. Affecte file is
1222 lib/silcclient/client_prvmsg.c.
1224 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Added function silc_client_add_channel,
1227 silc_client_replace_channel_id, and removed functions
1228 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1229 from client library.
1231 * Added cross reference of the joined channels to the
1232 SilcClientEntry, and changed the SilcChannelEntry's
1233 users list to SilcHashTable. The affected files are
1234 lib/silcclient/idlist.[ch].
1236 * Fixed a bug in hash table tarversing. While the hash table
1237 is traversed with SilcHashTableList the table must not be
1238 rehashed. It is now guaranteed that auto rehashable tables
1239 are not rehashed while tarversing the list. Also defined that
1240 silc_hash_table_rehash must not be called while tarversing
1241 the table. Added function silc_hash_table_list_reset that must
1242 be called after the tarversing is over. The affected files are
1243 lib/silcutil/silchashtable.[ch].
1245 * Changed all hash table traversing to call the new
1246 silc_hash_table_list_reset in server and in client library.
1248 * Added function silc_client_on_channel to return the
1249 SilcChannelUser entry if the specified client entry is joined
1250 on the specified channel. This is exported to application as
1251 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1253 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1255 * Fixed founder regaining problem with JOIN command on normal
1256 server. The notify for mode change must be sent always and
1257 not only if !cmd->pending. Affected file silcd/command.c.
1259 * Fixed the WHOWAS command's reply sending to support the
1260 lists correctly. Affected file silcd/command.c.
1262 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1264 * When sending JOIN command to router for processing the
1265 sender's old command identifier was not saved back to the
1266 sender's command context, fixed now. The affected file is
1269 * Create the key in JOIN command of the router did not return
1270 the channel key, added check for this. Affected file is
1273 * Fixed a channel ID update bug in JOIN command reply. Do
1274 not directly upgrade the ID but call the function
1275 silc_idlist_replace_channel_id if the ID was changed.
1276 Affected file silcd/command_reply.c.
1278 * Fixed memory leaks from command calling if it would fail.
1279 Affected file silcd/command.c.
1281 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1283 * Applied patches from cras:
1285 Memory leak fixes around libaries, irssi window resize fix,
1286 new silclist.h and silcdlist.h, all extern inline changed to
1289 * Removed dotconf from lib/dotconf, not needed anymore.
1291 * Removed TRQ from lib/trq, not needed anymore.
1293 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1294 with server connections. Later this will be configurable
1295 in config file after new config file is done. Affected file
1298 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1300 * Fixed a crash in server related to channel announcements.
1301 Affected file silcd/server.c.
1303 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1305 * Fixed memory leaks in silc_server_create_new_channel*
1306 functions. Affected file silcd/server.c.
1308 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1309 which ID was changed. This way the router will send the
1310 user list for the channel again, and server won't be in
1311 desync in some rare circumstances. Affected file is
1312 silcd/packet_receive.c.
1314 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1316 * Check for NULL socket pointer in the function
1317 silc_server_packet_send_to_channel_real. Affected file
1318 silcd/packet_send.c.

1321 list. Affected file silcd/packet_receive.c.
1323 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1325 * Fixed some header addition to Toolkit distribution in
1326 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1328 * Added lib/silcclient/client_ops_example.h as an template
1329 file for application programmers to quickly start using
1330 the SilcClientOperation functions in their application.
1331 Updated the lib/silcclient/README as well to tell about this
1332 nice file made available.
1334 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1336 * Call silc_server_remove_from_channels when removing client
1337 entry when NO_SUCH_CLIENT_ID was received. Affected file
1338 is silcd/command_reply.c.
1340 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1342 * Added server & router operator statistics updating. Affected
1343 file silcd/packet_receive.c and silcd/command.c.
1345 * Fixed the SERVER_SIGNOFF notify handling on normal server
1346 not to save the history information for clients. Same was
1347 fixed earlier in remove_clients_by_server function, but not
1348 here. Affected file silcd/packet_receive.c.
1350 * Raised the default connection-retry count from 4 to 7 in
1351 server. Affected file silcd/server.h.
1353 * Cancel any possible reconnect timeouts when we start the
1354 key exchange. Affected file silcd/server.c.
1356 * Do not reconnect on connection failure when SCONNECT was
1357 given. Affected files silcd/server.[ch].
1359 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1363 * Fixed the NICK command to always give the unformatted
1364 nickname to the one giving the NICK command. If unformatted
1365 nickname is cached already it will be formatted and the
1366 local entry will always get the unformatted nickname.
1367 Affected file lib/silcclient/idlist.c.
1369 * Fixed some double frees from client library commands.
1370 Affected file is lib/silcclient/command.c.
1372 * Fixed CUMODE command in server to assure that no one can
1373 change founder's mode than the founder itself, there was a
1374 little bug. Affected file silcd/command.c.
1376 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1378 * Removed the SilcClientCommandDestructor from the client
1379 libary, it is not needed anymore. Affected files are
1380 lib/silcclient/silcapi.h, command[_reply].[ch],
1381 client_notify, idlist.c.
1383 * Fixed GETKEY command to first resolve client, and then
1384 resolve the server only if the client was not found, instead
1385 of resolving both at the same time. Affected file is
1386 lib/silcclient/command.c.
1388 * Added silc_client_start_key_exchange_cb and lookup the
1389 remote hostname and IP address before starting the key
1390 exchange with server. The affected file is
1391 lib/silcclient/client.c.
1393 * The server's public key is now saved using the IP address
1394 of the server and not the servername for the filename.
1395 The hostname public key filename is checked as an fall back
1396 method if the IP address based filename is not found.
1398 Fixed the GETKEY command to save the fetched server key
1399 in correct filename.
1401 Print the remote server's hostname now when new key is
1402 received during connection process. Affected file is
1403 irssi/src/silc/core/client_ops.c.
1405 * Return always our own public key to the client if it asks
1406 for it with GETKEY command. Affected file silcd/command.c.
1408 * Removed the use_auto_addr variable from default config
1409 file since it was in wrong section. Affected file is
1412 * Fixed TOPIC_CHANGE notification to not route it when it
1413 was sent using silc_server_send_notify_to_channel function.
1414 Affected file silcd/command.c.
1416 * Fixed silc_server_send_notify_kicked to send the kicker's
1417 Client ID also, it was missing. Affected files are
1418 silcd/command.c, silcd/packet_send.[ch].
1420 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1422 * Do not save client history information in SERVER_SIGNOFF.
1423 Fixes the bug in normal server that it does not detect
1424 the client becoming valid after the server becomes back
1425 online. Affected file silcd/server_util.c.
1427 * Added `sock_error' field into the SilcSocketConnection
1428 context. When error occurs during socket operation (read
1429 or write) the error is saved. Added also new function
1430 silc_socket_get_error to return human readable socket error
1431 message. Affected files are lib/silcutil/silcsockconn.[ch],
1432 lib/silcutil/unix/silcunixsockconn.c, and
1433 lib/silcutil/win32/silcwin32sockconn.c.
1435 * The server now prints the socket error message in the
1436 signoff for client. Affected file silcd/server.c.
1438 * Fixed the `created' channel information sending from router
1439 to server in JOIN command. Checks now whether the channel
1440 really was created or not and set it according that.
1442 Fixed the JOIN command to use the client entry's current
1443 ID during the joining procedure instead of the one it sent
1444 in the command (it is checked though), since it can change
1445 between the packet processing and command processing, and
1446 would just case unnecessary pain in the client end. Affected
1447 file silcd/command.c.
1449 * Fixed a channel key payload sending to use correct channel
1450 ID when the server was forced to change the channel's ID by
1451 router. Router sent the key payload with the old Channel ID.
1452 Affected file silcd/packet_receive.c.
1454 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1456 * Call silc_server_save_channel_key only if the key payload
1457 was provided in the JOIN command's command reply. Affected
1458 file silcd/command_reply.c.
1460 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1462 * Fixed silc_mp_sizeinbase to return the value correctly with
1463 MPI. Affected file lib/silcmath/mp_mpi.c.
1465 * Fixed the stop_server signal to correctly stop the scheduler
1466 and gracefully stop the server when SIGTERM or SIGINT signals
1467 are received. Affected file silcd/silcd.c.
1469 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1471 * Simple handling of TERM and HUP signals. Also added some log
1472 flushing call around. Affected file is
1475 * Fixed small bugs in silclog.c. Now buffering output will take
1476 effect after 10 seconds since startup: This will ensure that
1477 no important startup messages are lost. Also output redirection
1478 will preserve original format ([Date] [Type] message).
1479 Affected file is lib/silcutil/silclog.c.
1481 * Added two options to the config file, in the logging section:
1482 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1483 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1485 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1487 * Do not print the warning about log files not being initialized
1488 more than once to avoid excess logging. Affected file is
1489 lib/silcutil/silclog.c.
1491 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1492 the SIM copying in make install in Makefile.am.pre.
1494 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1496 * Rewritten silclog APIs. Globally interesting changes follows:
1497 silc_log_set_files() changed to silc_log_set_file().
1498 silc_log_set_callbacks() changed to silc_log_set_callback().
1499 ROBOdoc documented silclog header file.
1500 SilcLogCb now returns bool to wether inihibit the default
1501 handler or not (to keep the old behaviour return always TRUE).
1502 The new APIs should also fix the problem of the
1503 silcd_error.log file that was written in the current directory.
1506 Log files streams will remain opened after silc_log_set_file()
1507 call, means less CPU usage notably on high traffic servers.
1508 File streams are now full buffered, and flushed to the disk
1509 every 5 minutes, lesses HD activity and CPU usage.
1510 Messages can be redirected, allowing admins to configure
1511 one single logfile for all server messages.
1512 the silc_log_quick global variable to activate fast-logging.
1513 Affected files lib/silcutil/silclog.[ch]
1515 * Changed some code to conform new silclog APIs. Affected
1516 files are doc/example_silcd.conf.in, silcd/server.c
1517 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1520 * Fixed a memory leak that could occur in some situations.
1521 Affected file silcd/serverconfig.c.
1523 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * Added the silc_client_del_client to remove the client from
1526 all channels as well. Affected file lib/silcclient/idlist.c.
1528 * Fixed the client library to correctly remove the client
1529 from all channels when the client entry is being destroyed.
1530 Affected file lib/silcclient/client_notify.c, command.c.
1532 * Added auto-nicking support to the client library. If the
1533 applicatio now sets client->nickname it will be sent to the
1534 server after connecting by the library. This way for example
1535 SILCNICK (or IRCNICK) environment variables will have effect
1536 and always change the nickname automatically to whatever
1537 it is wanted. Affected file lib/silcclient/client.[ch].
1539 * Renamed silc_server_command_bad_chars to the
1540 silc_server_name_bad_chars and moved it to the
1541 silcd/server_util.[ch]. Added also new function
1542 silc_server_name_modify_bad to return nickname that
1543 includes bad characters as new nickname without those
1544 bad characters. This check and modify is now used in
1545 silc_server_new_client when the username is initially set
1546 as nickname, so it must be checked to be valid nickname.
1547 Affected file silcd/packet_receive.c.
1549 * The nickname length is now taken from the packet for real
1550 and not trusted to strlen() since it clearly can return
1551 wrong length for nickname including bad characters. This
1552 also applies to channel names. Affected file silcd/command.c.
1554 * Removed the lib/silcsilm/modules directory. Modules are now
1555 compiled into the lib/silcsim. Fixed the copying of the
1556 modules to follow symbolic links in Makefile.am.pre.
1558 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1560 * Fixed silc_string_regexify list creation. Fixes bugs with
1561 BAN and INVITE commands in server. The affected file is
1562 lib/silcutil/unix/silcunixutil.c.
1564 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * Removed the command destructor entirely from the server's
1567 command and command reply routines. It is not needed, and
1568 its usage was buggy and caused crashes. Affected files are
1569 silcd/command[_reply].[ch].
1571 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Cancel protocol and NULL sock->protocol if timeout
1574 occurred during protocol. Affected file silcd/server.c.
1576 * Cancel protocol timeouts always before calling the final
1577 callback, to assure that after final callback is called
1578 no other state will be called for the protocol anymore.
1579 Affected file silcd/protocol.c.
1581 * Print error log if incoming connection configuration could
1582 not be found. Affected file silcd/server.c.
1584 * Fixed JOIN command to correctly save the founder mode
1585 to the client on normal SILC server, when the channel
1586 was created by the router. Affected file silcd/command.c.
1588 * Fixed LIST command (hopefully) to send correct reply
1589 packets. Affected file silcd/command.c.
1591 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * The silc_packet_receive_process now returns FALSE if the
1594 read data was invalid packet, and TRUE if it was ok.
1596 The server now checks that if unauthenticated connection
1597 sends data and its processing fails the server will close
1598 the connection since it could be a malicious flooder.
1600 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1602 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Make sure the warning about error opening a log file is
1605 printed only once and not everytime it fails (produces
1606 too much useless log). Affected file lib/silcutil/silclog.c.
1608 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1610 * Made the silc_server_daemonise() function more readable.
1611 Affected file silcd/server.c.
1613 * Pid file is now optional, the user may comment it out from
1614 the config file. Removed define SILC_SERVER_PID_FILE, we
1615 don't need a default any longer. Affected file
1616 configure.in.pre, lib/Makefile.am.pre.
1618 * Make some use of the pid file. The server now dies at startup
1619 if it detects a valid pid file on his path. The server would
1620 die anyway in this circumstance, because of the bind() failure.
1621 Affected file silcd/silcd.c.
1623 * No longer compiling lib/dotconf.
1625 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1627 * Fixed JOIN command parsing not to crash. Affected file
1628 lib/silcclient/command.c.
1630 * Fied the NICK_CHANGE notify to add the new client entry
1631 even it is resolved. This removes an <[unknown]> nick
1632 thingy bug in the client. Affected file is
1633 lib/silcclient/client_notify.c.
1635 * Do not try to allocate 0 bytes (efence does not like it)
1636 in lib/silccore/silccomand.c when encoding payload.
1638 * Do not take IRCNICK as nickname in Irssi SILC client since
1639 it is not possible to set nickname before hand connecting
1640 the server (TODO has an entry about adding auto-nicking
1643 * Changed the silc_server_command_pending to check whether
1644 there already exists an pending entry with the specified
1645 command, command identifier and pending callback. This is
1646 to fix IDENTIFY and WHOIS related crashes that may register
1647 multiple pending commands with same identifier. Affected
1648 file silcd/command.c.
1650 * Fixed the server to reconnect to the router even if it
1651 was already reconnecting and EOF was received. This to
1652 fix a possibility that the server wouldn't ever try to
1653 auto-reconnect to the router. Affected file silcd/server.c.
1655 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * Fixed the server's password authentication to use the
1658 length of the locally saved password, and not the one
1659 sent in the packet. Affected file silcd/protocol.c.
1661 * Fixed same password authentication problem in the
1662 Authentication Payload handling routines in
1663 lib/silccore/silcauth.c.
1665 * Yet another password authentication problem fixed with
1666 channel password handling in silcd/command.c.
1668 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * If first character of string in silc_parse_userfqdn is '@'
1671 then do not parse it. Affected file is
1672 lib/silcutil/silcutil.c.
1674 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Fixed minor bug in IDENTIFY command reply sending, which
1677 caused various weird problems during JOIN when it was
1678 resolving names for users. Affected file silcd/command.c.
1680 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Fixed the IDENTIFY command reply sending to chech better valid
1683 clients. It was possible to send incomplete list of replies.
1684 Affected file silcd/command.c.
1686 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Added silc_client_command[s]_[un]register functions now to
1689 dynamically register the commands in client library. Removed
1690 the static table of commands. This allows the client library
1691 to call commands without causing the application to know about
1692 what commands library has called.
1694 Removed the INFO command reply kludge to detect when the command
1695 was called by library. Now library use its own command reply
1696 function for INFO command.
1698 Added function silc_client_command_call to call a command.
1699 Application can use it to call command, not access the structure
1702 Now all commands that are sent by the client library (not
1703 explicitly sent by application) use own command reply functions.
1705 Affected files around lib/silcclient/ and in
1706 irssi/src/silc/core/.
1708 * Fixed the WHOIS command reply sending to chech better valid
1709 clients. It was possible to send incomplete list of replies.
1711 Fixed the WHOIS and IDENTIFY to send the request to router
1712 if normal server did not do it and did not find any results.
1714 Affected file silcd/command.c.
1716 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Moved the internal data from SilcClient context into its
1719 own file, not accesible to application. Affected files
1720 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1721 and other files in client library.
1723 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Added doc/examples installation target in Makefile.am.pre.
1728 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1730 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1731 commands the found client entry will be removed from the
1732 cache, after notifying application about the error. Affected
1733 file lib/silcclient/command_reply.c.
1735 * Changed the /MSG to check for exact nickname user gave, and
1736 not let `nick' match `nick@host' if it is only one found. Now,
1737 user must type the exact nickname (like nick@host2) even if
1738 there are no more than one same nicks found. This is to avoid
1739 a possibility of sending nickname to wrong nickname since
1740 `nick' could match `nick@host'. Affected file is
1741 irssi/src/core/silc-servers.c.
1743 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Do not print "you are now server operator" or similar when
1746 giving /away command. Affected files are
1747 irssi/src/silc/core/client_ops.c, silc-servers.h.
1749 * Made the silc_server_command_pending_error_check to send
1750 the same command reply payload it received back to the
1751 original sender of the command. This way all arguments
1752 that was received by the server will be received by the
1753 client too. Affected file silcd/command.c.
1755 * Added the silc_idcache_add to return the created cache entry
1756 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1758 * Add global clients to expire if they are not on any channel.
1759 This is because normal server will never know if they signoff
1760 if they are not on any channel. The cache expiry will take
1761 case of these entries. This is done by normal servers only.
1762 The affected files are silcd/command_reply.c,
1763 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1765 * If server receives invalid ID notification for WHOIS or
1766 IDENTIFY and the ID exists in the lists, it is removed.
1767 Affected file silcd/command_reply.c.
1769 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1770 in client then client entry that it matches is searched and
1771 the nickname is printed on the screen for user. Affected
1772 file irssi/src/silc/core/client_ops.c.
1774 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Use cache entry expire time in the LIST command reply to
1777 purge old entries from the cache after the LIST command
1778 reply has been received. This way we don't have non-existent
1779 entries in the cache for too long. Affected file is
1780 silcd/command_reply.c.
1782 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * If we are normal server, and we've not resolved client info
1785 in WHOIS or IDENTIFY from router, and it is global client,
1786 we'll check whether it is on some channel. If it is not
1787 then we cannot be sure about its validity and will resolve it
1788 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1789 file silcd/command.c.
1791 * Search channel by name (if possible) rather than by ID
1792 in IDENTIFY command's command reply. Affected file is
1793 silcd/command_reply.c.
1795 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1798 Updated specs and implemented it. Affected file silcd/command.c,
1799 silcd/packet_send.c and silcd/packet_receive.c.
1801 * Implemented the <founder auth> payload handling in the JOIN
1802 command. If provided all conditions for channel joining
1803 except requirement to provide correct passphrase can be
1804 overrided by the channel founder. Updated the protocol specs.
1805 Affected file silcd/command.c.
1807 Added support for founder auth in JOIN command in client
1808 library. Fixed the parsing of the JOIN command now to support
1809 all options as they should be. The affected file is
1810 lib/silcclient/command.c.
1812 * Optimized the WHOIS and IDENTIFY commands to send the request
1813 to router only if it includes nicknames or other names. If
1814 they include only IDs then check the local cache first before
1815 routing. Affected file is silcd/command.c.
1817 * Added channels topic announcements. Affected file is
1818 silcd/packet_receive.c and silcd/server.c.
1820 * Fixed the silc_server_send_notify_topic_set to really destine
1821 the packet to channel. Affected file silcd/packet_send.c.
1823 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1824 library. Affected file lib/silcclient/client_notify.c.
1826 * Added UMODE announcements. Affected file silcd/server.c.
1828 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * Memory leak fixes in:
1832 lib/silcutil/silcsockconn.c
1833 lib/silcske/silcske.c
1834 lib/silcske/groups.c
1836 lib/silccrypt/silcpkcs.c
1837 lib/silccore/silccommand.c
1838 lib/silccore/silcidcache.c
1843 * ROBOdoc documented the lib/silcske/groups.h file and a
1844 bit changed the interface for better.
1846 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1848 * Update the client entry context in the ID cache after
1849 nick change. Affected file lib/silcclient/command.c.
1850 Fixes the CUMODE command when regaining founder privileges,
1851 and a little WHOIS problem.
1853 * Fixed silc_net_gethostbyname to correctly call the
1854 inet_ntop. Affected file lib/silcutil/silcnet.c.
1856 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1858 * Added IPv6 support checking to the configure.in.pre, added
1859 also --enable-ipv6 option to override the check. Affected
1860 file configure.in.pre.
1862 * The silc_thread_create now calls the start function
1863 directly if threads support is not compiled in. Removes
1864 ugly #ifdef's from generic code. Affected files are
1865 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1867 * Added silc_net_gethostby[name/addr]_async to asynchronously
1868 resolve. Affected files are lib/silcutil/silcnet.[ch].
1870 * Added support for rendering IPv6 based server, client and
1871 channel IDs. Affected file lib/silcutil/silcutil.c.
1873 * Added support for creating IPv6 based server IDs. Affected
1874 file is silcd/serverid.c.
1876 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1878 * Added silc_net_gethostby[addr/name] into the
1879 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1880 routines. Added silc_net_is_ip[4/6]. Affected file is
1881 lib/silcutil/unix/silcunixnet.c. All routines that take
1882 address as argument now supports both IPv4 and IPv6 addresses.
1884 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1886 * Fixed LIST command reply sending in server. Affected file
1889 * Server now sends the kicker's client ID in the KICK notify
1890 to the kicked client. Affected file silcd/command.c.
1892 * The client library now parses the kickers client ID and
1893 UI displays it. Affected files lib/silcclient/client_notify.c
1894 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1896 * Made all payload parsing function prototypes consistent.
1897 They all take now const unsigned char * and uint32 pair as
1898 the payload data instead of SilcBuffer. Changes all around
1899 the source tree. Other unsigned char* -> const unsigned char*
1900 changes around the tree as well.
1902 * Optimized SFTP client and server packet sending not to
1903 allocate new buffer for each packet but to recycle the
1904 first allocated buffer. Affected files are
1905 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1907 * Optimized the SFTP client to use SilcList instead of
1908 SilcDList for requests, because it is faster. Affected file
1909 is lib/silcsftp/sftp_client.c.
1911 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1912 into lib/silccore/silcid.[ch].
1914 Renamed silcpayload.[ch] into silcargument.[ch].
1916 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * If client entry is deleted with active key agreement
1919 session, abort the session.
1921 The silc_client_abort_key_agreement now calls the completion
1922 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1924 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1927 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Don't use __restrict in older GCC's. Affected file is
1930 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1932 * silc_net_localhost now attempts to reverse lookup the
1933 IP/hostname. Affected file lib/silcutil/silcnet.c.
1935 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1936 command. It can be used to gain founder privileges at
1937 the same time when joining the channel.
1939 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1940 kicker's client ID as well. Updated protocol specs.
1942 Defined that the server must send SILC_COMMAND_IDENTIFY
1943 command reply with error status to client who sent
1944 private message with invalid client ID.
1946 Updated the protocol specification.
1948 * Added silc_server_send_command_reply to send any
1949 command reply. Affected file silcd/packet_send.[ch].
1951 * Added silc_id_payload_encode_data to encode ID payload
1952 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1954 * The server now send IDENTIFY command reply with error
1955 status if client ID in private message is invalid. Affected
1956 file silcd/packet_receive.c.
1958 * Save the server key file with server's IP address in
1959 the filename instead of hostname. The affected file is
1960 irssi/src/silc/core/client_ops.c.
1962 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1967 * Added libtool support for compiling shared objects in
1968 lib/silcsim. Affected file configure.in.pre and
1969 lib/silcsim/Makefile.am. Original patch by cras.
1971 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Pid file configuration, and server's config file fixes
1974 patch by toma. Updated CREDITS file.
1976 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Fixed silc_client_channel_message to not try to decrypt
1979 the message twice if it resolved the destination client
1980 information. This could cause of dropping one channel
1981 message. Affected file lib/silcclient/client_channel.c.
1983 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1986 lib/silcclient/client.c. This function is used when the SILC
1987 Client is run under some other scheduler, or event loop or
1988 main loop. On GUI applications, for example this may be
1989 desired to used to run the client under the GUI application's
1990 main loop. Typically the GUI application would register an
1991 idle task that calls this function multiple times in a second
1992 to quickly process the SILC specific data.
1994 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1996 * Fixed silc_server_drop() for dropping the supplementary
1997 groups as well, this could cause a security hole on some
2000 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

2006 to run server on foreground. A patch by debolaz.
2007 Affected files silcd/server.c, silcd/silcd.c.
2009 * Fixed MOTD to return the MOTD file server name. Affected
2010 file silcd/command.c.
2012 * Added INFO command reply handling to the Irssi SILC Client.
2013 Affected file irssi/src/silc/core/client_ops.c.
2015 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Fixed the silc_idcache_list_* routines to really support
2018 the dynamic list. Fixes a crash. Affected file is
2019 lib/silccore/silcidcache.c.
2021 * Fixed the LIST command reply to really call LIST command's
2022 pending callbacks. Affected file silcd/command_reply.c.
2024 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Update conn->local_entry->nickname after giving NICK
2027 command. Affected file lib/silcclient/command.c.
2029 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2031 * Added the [pid] option to the silcd configuration file
2033 Affected files: serverconfig.[ch] and silcd.c
2035 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Save fingerprint in WHOIS command reply in server.
2038 Affected file silcd/command_reply.c.
2040 * Fixed NICK commands pending callback registration.
2041 Affected file lib/silcclient/command.c.
2043 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Use ++server->cmd_ident when sending commands in server,
2046 instead of random number. Affected file silcd/command.c.
2048 * Fixed GETKEY command reply to call actually GETKEY pending
2049 command callbacks. Affected file silcd/command_reply.c.
2051 * A bit stricter check for nicknames. Check for same nickname
2052 in NICK command also. Affected file silcd/command.c.
2054 * Do not call INFO command everytime client ID changes, only
2055 during first connecting. Affected file lib/silcclient/client.c.
2057 * Set the new nickname only after successful command reply for
2058 NICK command is returned by server. Affected file
2059 lib/silcclient/command.c.
2061 * Remove nicknames from nicklist during server_signoff notify.
2062 Should fix /NAMES bit more. The affected file is
2063 irssi/src/silc/core/silc-channels.c.
2065 * Added `fingerprint' field to the SilcIDListData in the
2066 silcd/idlist.h to hold the fingerprint of the client's
2069 Send the fingerprint of the client's public key in WHOIS
2072 Affected files silcd/command.c, and silcd/idlist.[ch].
2074 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2075 create fingerprint from given data.
2077 * Show the fingerprint of the client's public key in WHOIS.
2078 Affected files irssi/src/module-formats.[ch] and
2079 irssi/src/silc/core/client_ops.c.
2081 * Format the multiple same nicknames also during JOIN and
2082 NICK_CHANGE notifys. Affected file is
2083 lib/silcclient/client_notify.c.
2085 * Do not print error on screen for invalid private message
2086 payload since it can come if someone is sending private
2087 messages with wrong key. Affected file
2088 lib/silccore/silcprivate.c.
2090 * Fixed multiple concurrent /PING crash. Affected file
2091 lib/silcclient/command.c.
2093 * Changed the wrong ID encoding. All IP addresses must be
2094 in MSB first order in encoded format. They were encoded
2095 wrong and was in LSB format. Affected files are
2096 silcd/serverid.c, lib/silcutil/silcutil.c.
2098 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2100 * Call the `connect' client operation through the scheduler
2101 in case of error. Affected file lib/silcclient/client.c.
2103 * Call the `failure' client operation even if the error
2104 occurred locally during a protocol. Affected file is
2105 lib/silcclient/protocol.c.
2107 * Added support of sending LIST command to router from normal
2108 server. This way normal server can get list of all channels
2109 in the network too. Fixed the channel list sending in the
2110 server too. Affected files are silcd/command.c, and
2111 silcd/command_reply.[ch].
2113 * Added silc_server_update_channels_by_server and
2114 silc_server_remove_channels_by_server. They are used during
2115 disconnection of primary router and in backup router protocol.
2116 Affected file silcd/server_util.[ch], silcd/server.c and
2117 silcd/server_backup.c.
2119 * Fixed channel adding to global list in IDENTIFY command
2120 reply in server. Affected file silcd/command_reply.c.
2122 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2124 * If the incoming packet type is REKEY or REKEY_DONE process
2125 that packet always synchronously. Fixes yet another MAC
2126 failed error on slow (dialup) connections. Affected file
2127 lib/silcclient/client.c and silcd/server.c.
2129 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Call check_version SKE callback for initiator too. Affected
2132 file lib/silcske/silcske.c.
2134 * Implemented fix for security hole found in the SKE that was
2135 fixed in the specification few days back; the initiator's
2136 public key is now added to the HASH value computation.
2137 Added backwards support for the old way of doing it too, for
2138 old clients and old servers. Affected file is
2139 lib/silcske/silcske.c.
2141 * Enabled mutual authentication by default in SKE. If initiator
2142 is not providing mutual authentication the responder will
2143 force it. This will provide the proof of posession of the
2144 private key for responder. The affected files are
2145 lib/silcclient/protocol.c and silcd/protocol.c.
2147 * Do not cache anymore the server's public key during SKE.
2148 We do mutual authentication so the proof of posession of
2149 private key is done, and if the server is authenticated in
2150 conn auth protocol with public key we must have the public
2151 key already. Affected file silcd/protocol.c.
2153 * Added new global debug variable: silc_debug_hexdump. If
2154 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2155 file lib/silcutil/silclog.[ch].
2157 * Fixed compilation warning due to char * -> const char *.
2158 Affected files lib/silcutil/silcnet.h, and
2159 lib/silccore/silcauth.[ch].
2161 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Fixed CMODE command when new channel key was created. If
2164 the creation failed the old key was removed. Next time giving
2165 same command would crash the server since the old key was
2166 freed already. Affected file silcd/command.c.
2168 * Fixed the silc_server_announce_get_channels to not crash
2169 on reconnect. Affected file silcd/server.c.
2171 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Added silc_log_set_debug_string function to set a regex
2174 string to match for debug output. Only the function names,
2175 or filenames matching the given debug string is actually
2176 printed. This way it is possible to filter out those debug
2177 strings that user is not interested in.
2179 Fixed a bug in silc_string_regexify.
2181 Affected files lib/silcutil/silclog.[ch], and
2182 lib/silcutil/unix/silcunixutil.c.
2184 * Changed the -d options in both server and Irssi SILC client
2185 to take the debug string as argument. Affected files
2186 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2188 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Added silc_hash_babbleprint to create a Bubble Babble
2191 Encoded fingerprint. The encoding is developed by Antti
2192 Huima (draft-huima-babble-01.txt), and it creates human
2193 readable strings out of binary data. Affected file
2194 lib/silccrypt/silchash.[ch].
2196 * Print the babble print now in addition of fingerprint as well
2197 in Irssi SILC client. Affected files are
2198 irssi/src/fe-common/silc/module-formats.[ch],
2199 irssi/src/fe-common/silc/core/client_ops.c.
2201 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Fixed a security problem found in SKE. The initiator's
2204 public key too is now added to the HASH hash value creation
2205 which is signed by the responder to create the SIGN value.
2206 This will prevent anyone in the middle to lie to the responder
2207 about the initiator's public key. If this is done now, the
2208 man in the middle will get caught. Updated the protocol
2211 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Better installation directory handling. Configure module
2214 paths and other paths automatically to example_silc* files
2215 in doc/. A patch by toma.
2217 * Fixed compiler warning from MPI library, and from SILC RNG.
2220 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2221 It can be configured with ./configure. A patch by toma.
2223 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Find correct make to use in prepare-clean. A patch by
2226 toma. Affected file prepare-clean.
2228 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2230 * Added irssi variables use_auto_addr, auto_bind_ip,
2231 auto_bind_port and auto_public_ip.
2233 * Changed the interface for silc_client_send_key_agreement
2234 in lib/silcclient/silcapi.h
2238 irssi/src/silc/core/silc-core.c
2240 lib/silcclient/silcapi.h
2241 irssi/src/silc/core/silc-channels.c
2242 lib/silcclient/client_keyagr.c
2245 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Added silc_pkcs_public_key_compare to compare two
2248 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2250 * Check that the client who set the founder mode on the
2251 channel is the same client that is giving the founder
2252 mode to itself. It is done by comparing the saved public
2253 key (it is saved even in the authentication is passphrase).
2254 Affected file silcd/command.c.
2256 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Do not process packet for disconnected socket connection.
2259 Affected file lib/silccore/silcpacket.c.
2261 * Process the DISCONNECT packet through scheduler in the
2262 client library. Affected file lib/silcclient/client.c.
2264 * Fixed the silc_client_packet_parse to not to increase
2265 the packet sequence number if the conn->sock and the
2266 current socket connection is not same. This can happen
2267 for example during key agreement when the conn includes
2268 multiple socket connections (listeners). Affected file
2269 lib/silcclient/client.c.
2271 * The sender of the file transfer request now provides also
2272 the pointer (listener) for the key exchange protocol. If
2273 the listener cannot be created then it sends empty key
2274 agreement and lets the receiver provide the listener.
2276 Added `local_ip' and `local_port' arguments to the
2277 silc_client_file_send. If they are provided they are used,
2278 if not then it will attempt to find local IP address, if
2279 not found or bind fails then the remote client will provide
2282 Affected files are lib/silcclient/client_ftp.c and
2283 lib/silcclient/silcapi.h.
2285 * Extended the FILE SEND command to support defining the
2286 local IP and port for key exchange listener. They are
2287 optional. Affected file irssi/src/silc/core/silc-servers.c.
2289 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Defined to WHOIS command reply the sending of fingerprint
2292 of the client's public key (if the proof of posession of the
2293 corresponding private key is verified by the server).
2294 Updated to the protocol specification.
2296 * Added support of receiving the client's public key's
2297 fingerprint in command reply in client library. Affected
2298 file is lib/silcclient/command_reply.c, and
2299 lib/silcclient/idlist.[ch].
2301 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Do not send over 128 chars long nickname to the server
2304 in NICK command. Affected file lib/silcclient/command.c.
2306 * Do not send over 256 chars long channel names to the server
2307 in JOIN command. Affected file lib/silcclient/command.c.
2309 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Assure that silc_server_close_connection cannot be called
2312 twice for same socket context. Affected file is
2315 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Send error message to application if opening file for
2318 writing during file transfer fails. Affected file is
2319 lib/silcclient/client_ftp.c.
2321 Remove all file transfer sessions for a client that we're
2322 removing from ID cache.
2324 Affected file is lib/silcclient/client_ftp.c.
2326 * Fixed silc_net_addr2bin to return correct address. Affected
2327 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2329 * Fixed file transfer session removing on signoff notify.
2330 Affected file irssi/src/silc/core/silc-servers.c.
2332 * Added the SilcClientFileError to be returned in the monitor
2333 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2334 Affected file lib/silcclient/silcapi.h.
2336 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Fixed a crash in silc_client_ftp_free_sessions and
2339 silc_client_ftp_session_free_client. Affected file
2340 lib/silcclient/client_ftp.c.
2342 * Added `disabled' field in the SilcChannelEntry in the server
2343 to indicate if the server entry is disabled. Affected file
2344 silcd/idlist.h, silcd/command[_reply].c.
2346 * SILC server adds now /var/run/silcd.pid everytime it is
2347 started. Affected file silcd/silcd.c.
2349 * Added silc_server_packet_send_clients to send a packet to
2350 the provided table of client entries. Affected file

2353 * Fixed a crash in client resolving in client_prvmsg.c in
2354 client library. Affected file lib/silcclient/client_prvmsg.c.
2356 * Do not actually remove the client directly from ID cache
2357 during SERVER_SIGNOFF, but invalidate it. This way we
2358 preserve the WHOWAS info for the client. Affected file
2359 silcd/server_util.c.
2361 * Fixed SERVER_SIGNOFF notify handling in the server. The
2362 server is now able to process incoming SERVER_SIGNOFF notify
2363 for a server that it doesn't even know about. It will remove
2364 the clients provided in the notify. Affected file
2365 silcd/packet_receive.c.
2367 * Check for partial packet in data queue after every packet that
2368 was found from the queue. Return and wait for more data if
2369 there is partial data in queue. Affected file is
2370 lib/silccore/silcpacket.c.
2372 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Added SilcClietFileError enum to indicate error in
2375 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2376 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2377 Affected files lib/silcclient/silcapi.h and
2378 lib/silcclient/client_ftp.c.
2380 * Check that newsize in silc_buffer_realloc is larger than
2381 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2383 * Added better monitor of file transfers. It now monitors
2384 key agreement protocol during the file transfer too. Added
2385 error reporting too. Affected files
2386 irssi/src/silc/core/silc-servers.c,
2387 irssi/src/fe-common/silc/module-formats.[ch].
2389 * Wrote a help file for FILE command.
2391 * Added silc_rng_global_get_byte_fast to get not-so-secure
2392 random data as fast as possible. Random data is read from
2393 /dev/urandom if available and from the SILC RNG if not
2394 available. It is used in padding generation. Affected file
2395 lib/silccrypt/silcrng.[ch].
2397 * All packets in client library are now processed synchronously.
2398 Optimized packet processing a lot. Affected file
2399 lib/silcclient/client.c.
2401 * All server connection packets are processing synchronously
2402 now in server, to optimize packet processing. Affected file
2405 * Include files are installed now only in Toolkit distribution
2406 if make install is given. Affected files: all Makefile.am's.
2408 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2410 * Assure that silc_client_notify_by_server_resolve does not
2411 resolve the client information multiple times. If it cannot
2412 be found by the first it cannot be found at all. Affected
2413 file lib/silcclient/client_notify.c.
2415 * Fixed WHOWAS command reply calling. Affected file
2416 lib/silcclient/command_reply.c.
2418 * Removed all references to silc_idlist_get_client from the
2419 Irssi SILC client since that call is internal call used by
2420 the library. The Irssi SILC client will use now client
2421 retrieval functions found in silcapi.h.
2423 * Fixed a bug in resolving nickname info before sending
2424 private message. It used freed memory. Affected file
2425 irssi/src/silc/core/silc-servers.c.
2427 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Assure my_channels statistics cannot go negative in server.
2430 Affected files silcd/server.c, silcd/server_util.c.
2432 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2436 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

2442 lib/sftp/sftp_fs_memory.c.
2444 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Added silc_net_localip to return local host's IP address.
2447 Affected file lib/silcutil/silcnet.[ch].
2449 * If key exchange or rekey protocol is active for a connection
2450 parse all packets syncronously since there might be packets
2451 in packet queue that we are not able to process without first
2452 processing packets before them. Affected file silcd/server,
2453 lib/silcclient/client.c.
2455 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2456 whether library should continue processing the packet.
2457 Affected file lib/silccore/silcpacket.h.
2459 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2460 SilcSFTPMonitorData to SFTP server to monitor various
2461 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2462 lib/silcsftp/sftp_server.c.
2464 * Added silc_file_size to return file size. Affected file
2465 lib/silcutil/silcutil.[ch].
2467 * Implemented the file transfer support for the client library.
2468 Added preliminary support for simple client to client one-file
2469 transmission. Affected file lib/silcclient/client_ftp.c,
2470 lib/silccilent/client.[ch].
2472 * Added new local command FILE to the Irssi SILC Client.
2473 It is used to perform the file transfer. It has subcommands
2474 SEND, RECEIVE, SHOW and CLOSE. Affected files
2475 irssi/src/silc/core/client_ops.c,
2476 irssi/src/silc/core/silc-server.[ch].

2487 silc_file_open and silc_file_close. Affected files
2488 lib/silcutil/silcutil.[ch].
2490 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Resolve the client info when received private message or
2493 channel message for a client which nickname we don't know.
2494 Affected files lib/silcclient/client_prvmsg.c and
2495 lib/silcclient/client_channel.c.
2497 * Do not crash in /KEY if client is not connected. Affected
2498 file irssi/src/silc/core/silc-channels.c.
2500 * Added SilcClientStatus field to the SilcClientEntry in the
2501 lib/silcclient/idlist.h.
2503 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2504 is incomplete and is being resolved, it won't be resolved
2507 Make sure also that USERS command reply does not resolve
2508 twice information. Affected file is
2509 lib/silcclient/command_reply.c.
2511 Make sure that silc_client_get_clients_by_list does not
2512 resolve twice same information.
2514 * Check for valid client->id in the silc_server_free_client_data.
2515 Affected file silcd/server.c.
2517 * Fixed /GETKEY nick@server not to crash if the server entry
2518 is not found. Affected file lib/silcclient/command.c.
2520 * Fixed the silc_server_check_cmode_rights to check the
2521 requested modes correctly. Affected file silcd/command.c.
2523 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Better checks for non-printable chars in nick added.
2526 Affected file silcd/command.c.
2528 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2530 * Call the silc_server_udpate_servers_by_server in the
2531 primary router that comes back online in the backup resuming
2532 protocol. Otherwise it routes packets wrong. Affected file
2533 silcd/server_util.[ch], silcd/server_backup.c.
2535 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2538 lib/silcutil/silcbuffmt.[ch].
2540 * Redefined the SILC packet header to include the padding
2541 length. Affected file lib/silccore/silcpacket.[ch].
2543 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2544 length for maximum padding up to 128 bytes). Affected
2545 file lib/silccore/silcpacket.h.
2547 * Removed all backwards support for old 0.5.x MAC thingies.
2548 The SILC packet header change makes it impossible to be
2549 backwards compatible.
2551 * Send the ENDING packet with timeout in the backup resuming
2552 protocol. This is to assure that all routers has connected
2553 to the primary router. Affected file silcd/server_backup.c.
2555 * Changed the RNG to take the first IV from random data. It
2556 used to take it from zero actually. Changed the RNG also
2557 to use /dev/urandom during session. /dev/random is used
2558 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2560 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Changed the SILC packet header to have the first two bytes
2563 (the packet length) encrypted. Affected files aroung the
2564 code tree, lib/silccore/silcpacket.[ch]. Removed the
2565 SilcPacketCheckDecrypt callback. It is not needed anymore
2566 since the silc_packet_receive_process will determine now
2567 whether the packet is normal or special.
2569 * Implemented the unidirectional MAC keys. Affected files
2570 lib/silcske/silcske.c, silcd/protocol.c and
2571 lib/silcclient/protocol.c.
2573 * Implemented the packet sequence number to the MAC computation.
2574 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2575 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2576 lib/silcclient/protocol.c.
2578 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Allow backup router to announce servers. All servers
2581 announced by backup router are added to the global list
2582 automatically. Update hte server's socket to our primary
2583 router also when backup router announces a server.
2584 Affected file silcd/packet_receive.c.
2586 * Do not update the client->router in the function
2587 silc_server_udpate_clients_by_server if the client is on
2588 global list. We might fail to find any specific server
2589 for locally connected clients and local cell clients. They
2590 should still use the `from' and not `to' as client->router.
2591 This fixes backup router resuming protocol. Affected file
2592 silcd/server_util.c.
2594 * Decrease channel statistics count only if the channel
2595 deletion worked. Affected files are silcd/server.c and
2596 silcd/server_util.c.
2598 * Added silc_server_update_servers_by_server to update origin
2599 of all server entries. Used during backup router protocol.
2600 Affected files silcd/server_util.[ch], silcd/server.c. and
2601 silcd/backup_router.c.
2603 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2604 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2605 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2606 lib/silccrypt/silchmac.c.
2608 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Assure that router cannot reroute the same channel message
2611 to the sender. Affected file silcd/packet_receive.c.
2613 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Made better checks that the channel message is not sent
2616 to the router it came from. Affected file is
2617 silcd/packet_send.c. Fixed memory leak too.
2619 * Announce informations for incoming router connection, but
2620 only after checking if it is replaced by backup router.
2621 Affected file silcd/packet_receive.c.
2623 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2625 * Fixed the backup resuming protocol to work in multiple
2626 router environment. Affected file silcd/server_backup.c.
2628 * Route packet only to one router in the function
2629 silc_server_packet_send_to_channel. Affected file is
2630 silcd/packet_send.c.
2632 * Fixed silc_server_send_notify_dest to set the broadcast
2633 flag. Fixed the silc_server_send_notify_topic to actually
2634 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2635 Affected file silcd/packet_send.c.
2637 * Changed the SFTP Filesystem interface. Changed the
2638 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2639 the filesystem operation function. The SilcSFTPFilesystem
2640 is now a context that is allocated by all filesystem allocation
2641 functions and it already includes the operations structure
2642 and filesystem specific context. It is given as argument
2643 now to the silc_sftp_server_start. This made the interface
2644 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2645 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2647 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2649 * Changed the backup router adding and getting interfaces
2650 in the server. The router that will be replaced by the
2651 specified backup router is now sent as argument. Affected
2652 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2655 * Added silc_net_addr2bin_ne to return the binary form of
2656 the IP address in network byte order. Affected files
2657 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2659 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Check for existing server ID in silc_server_new_server
2662 and in silc_server_connect_to_router_final and remove the
2663 old entry if it exists. Affected file silcd/packet_receive.c,
2666 * Send the channel message always to only one router, either
2667 in upstream or downstream. Affected file is
2668 silcd/packet_send.c.
2670 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Wrote the definition of the backup resuming protocol to the
2673 protocol specification.
2675 * Removed one redundant channel key generation from normal
2676 server during joining procedure. Removed one redundant
2677 channel key sending from server to router during joining
2678 procedure. Affected file silcd/command.c.
2680 * Made minor bugfixes to the backup router resuming protocol.
2681 Affected file silcd/server_backup.c, server.c.
2683 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Added --disable-asm configuration option. Affected files
2686 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2689 * Implemented the backup resuming protocol that is used to
2690 resume the primary router position in the cell after the
2691 primary router comes back online. Affected files
2692 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2693 and silcd/server_util.[ch].
2695 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Sleep two (2) seconds after sending QUIT command to server.
2698 Affected file lib/silcclient/command.c.
2700 * Assure that if outgoing data buffer is pending do not force
2701 send any data. Affected file silcd/packet_send.c.
2703 * Assure that if outgoing data buffer is pending do not force
2704 send any data. Affected file lib/silcclient/client.c.
2706 * Implemented the backup router support when the primary router
2707 goes down. The servers and routers can now use the backup
2708 router as new primary router without loosing connectivity.
2710 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2712 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2713 in the server to indicate disabled entry. All data read
2714 from the connection will be ignored and no data is sent
2715 for entry that is disabled. Affected files are
2716 silcd/idlist.h, silcd/server.c.
2718 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Created SFTP client and server test programs in the
2721 lib/silcsftp/tests directory.
2723 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Implemented memory filesystem (virtual filesystem) for
2726 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2729 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Implemented the SFTP (SSH File Transfer Protocol) to the
2732 lib/silcsftp. It includes SFTP client and SFTP server
2735 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Moved lib/silccore/silcprotocol.[ch] to the
2738 lib/silcutil library.
2740 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2741 take variable argument list pointer as argument. Affected
2742 file lib/silcutil/silcbuffmt.[ch].
2744 * Added silc_buffer_set function that is used to set data
2745 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2746 Affected file lib/silcutil/silcbuffer.h.
2748 * Changed various routines in the core library to use the new
2749 silc_buffer_set instead of allocating new buffer only for
2752 * Added 64-bit value formatting and unformatting support to the
2753 silc_buffer_[un]format routines. Affected file is
2754 lib/silcutil/silcbuffmt.[ch].
2756 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2757 to includes/bitmove.h.
2759 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2761 * Fixed channel user mode saving in client library. Affected
2762 file lib/silcclient/command[_reply].c.
2764 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Defined the file transfer to the SILC Protocol. Added
2767 new packet type SILC_PACKET_FTP and defined File Transfer
2768 Payload. The mandatory file transfer protocol is SFTP
2769 (SSH File Transfer Protocol). Affected file in addition
2770 of the internet draft is lib/silccore/silcpacket.h.
2772 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2773 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2774 is used as part of backup router protocol when the primary
2775 router of the cell is back online and wishes to resume
2776 the position as primary router.
2778 * Redefined the MAC generation keys in the protocol. The
2779 same key is not used anymore in both direction. Both
2780 direction will now use different keys for sending and
2781 receiving. This fixes a potential security flaw. This
2782 change causes incompatibilities in the protocol.
2784 * Redefined also the MAC computation from the packet.
2785 An packet sequence number is now added to the MAC
2786 computation. This prevents possible replay attacks against
2787 the protocol. This change too causes incompatibilities
2790 Added `sequence' field to the SilcPacketContext to hold
2791 the current sequence number for the packet.
2793 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Added `created' field to the SilcIDListData in the file
2796 silcd/idlist.h to indicate the time when the entry was
2799 * Added `created' field to the SilcChannelEntry too. Affected
2800 file silcd/idlist.h.
2802 * Added `creation_time' aguments to all the announcement functions
2803 in the server. If it is provided then only the entries that
2804 was created after the provided time frame are actually
2805 announced. Affected file silcd/server.[ch].
2807 * The protocol says that the Channel ID's IP address must be
2808 based on the router's IP address. Added check for this in
2809 the silc_server_new_channel when processing incoming New Channel
2810 Payload. Affected file silcd/packet_receive.c.
2812 * Print out the correct version with --version in SILC client.
2813 Affected file irssi/src/silc/core/silc-core.c.
2815 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Fixed WHOWAS command to check for completnes of the client
2818 entry always, not just when the command is coming from client.
2819 Affected file silcd/command.c.
2821 * Added new function silc_server_packet_queue_purge to purge the
2822 outgoing data queue to the network. After the function returns
2823 it is guaranteed that the outgoing packet queue is empty.
2824 Affected file silcd/packet_send.[ch].
2826 * Purge the outgoing packet queue in the rekey protocol's final
2827 callback to assure that all rekey packets go to the network
2828 before quitting the protocol. Affected file silcd/server.c.
2830 * Added silc_client_packet_queue_parse as similar function as
2831 in server to the client library. The affected file is
2832 lib/silcclient/client.c.
2834 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Splitted silcd/server.c and created silcd/server_util.[ch]
2837 for utility functions.
2839 * Added new socket flag SILC_SF_DISABLED to indicate that the
2840 connection is open but nothing can be sent to or received from
2841 the connection. Affected file lib/silcutil/silsockconn.[ch].
2842 The checking for disabled socket is checked in the low level
2843 silc_socket_write and silc_socket_read functions.
2845 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Allow only nicknames and channel names that fits into the
2848 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2850 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2852 * When processing JOIN command reply in server check that if
2853 the channel exists in our global list we'll move it the local
2854 list. Affected file silcd/command_reply.c.
2856 * Fixed the check whether client is joined on the channel already
2857 in JOIN command. Affected file lib/silcclient/command.c.
2859 * Fixed the JOIN command reply to check whether the channel
2860 already exists. Affected file lib/silcclient/command_reply.c.
2862 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Added silc_ske_status_string to map the SKE error numbers
2865 to readable strings. The affected files are
2866 lib/silcske/silcske[_status].[ch].
2868 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Do not show the private channels on the WHOIS channel list
2871 as it is not allowed by the protocol. The affected file is
2874 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Assure that the packet length digged from the actual packet
2877 is something sensible in the silc_packet_decrypt_rest_special
2878 in lib/silccrypt/silcpacket.c.
2880 * Free and NULL the allocated pointer in silc_hmac_alloc if
2881 the HMAC allocation fails. The affected file is
2882 lib/silccrypt/silchmac.c.
2884 * Print the selected security properties to the log files in
2885 the server. Affected file silcd/protocol.c.
2887 * Add SKE's reference counter even if calling the completion
2888 callback manually. Otherwise it goes negative, although it
2889 does not cause any problems. The affected file is
2890 lib/silcske/silcske.c.
2892 * Remove the client entry with short timeout after giving the
2893 KILL command. Affected file lib/silcclient/command.c.
2895 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2896 case all found clients are already disconnected (WHOWAS would
2897 found them) in the server. Affected file silcd/command.c.
2899 * Update the last_receive (time of last data received) to be
2900 updated only when received private or channel message so that
2901 the idle time showed in WHOIS makes more sense.
2903 * Added boolean field `valid' in to the SilcClientEntry in the
2904 client library to indicate whether the entry is valid or not.
2905 This fixes the nickname change bug on channel when changing
2906 the nickname to be same than the old (like nick to Nick) the
2907 nickname formatter doesn't set the new nick anymore to Nick@host.
2908 Affected file lib/silcclient/idlist.[ch].
2910 * Now actually fixed the nickname changing on disconnection.
2911 Added new function silc_change_nick to the Irssi SILC Client.
2912 Affected file irssi/src/silc/core/client_ops.c,
2913 irssi/src/silc/core/silc-nicklist.[ch].
2915 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * Check that the public key exists in the GETKEY command before
2918 trying to encode it. Affected file silcd/command.c.
2920 * Print some notifications on received public keys with GETKEY
2921 command in the Irssi SILC Client. Affected files are
2922 irssi/src/fe-common/silc/module-formats.[ch],
2923 irssi/src/silc/core/client_ops.c.
2925 * Use IDENTIFY command to resolve the server information in the
2926 GETKEY command instead of INFO command. Affected file
2927 lib/silcclient/command.c.
2929 * All command reply functions in the client library now calls
2930 the pending command reply callbacks even if an error has
2931 occurred. The server has done this a long time and now it was
2932 time to move the client library to this as well. Now all
2933 errors can be delivered back to the pending command reply
2934 callbacks if necessary. Affected files are
2935 lib/silcclient/command[_reply].[ch].
2937 * Change the nickname on disconnection back to the username
2938 because in reconnect the server will enforce it to it anyway.
2939 Affected file irssi/src/silc/core/silc-servers.c.
2941 * Fixed a config file parsing bug in the Irssi SILC client.
2942 Affected file irssi/src/silc/core/clientconfig.c.
2944 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * When printing the channel mode on JOIN, verify that the
2947 channel key and channel's HMAC are valid. Affected file
2948 irssi/src/silc/core/client_ops.c.
2950 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2953 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2954 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2956 * Removed channel key rekey task deleting from the function
2957 silc_server_save_channel_key. Affected file silcd/server.c.
2958 Added explicit timeout task context instead that is used to
2959 delete the task if we are registering a new task before the
2960 new task has elapsed.
2962 * When channel key rekey occurs the client library now saves
2963 the old channel key for a short period of time (10 seconds) and
2964 is able to use it in case some is still sending channel
2965 messages encrypted with the old key after the rekey. Affected
2966 file lib/silcclient/[idlist.h|client_channel.c].
2968 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Added check to the silc_server_new_id_real to not accept
2971 new ID if it is the sender's own ID. Affected file is
2972 silcd/packet_receive.c.
2974 * Assure that we do not announce ourself or the one we've
2975 sending our announcements when we're router and are announcing
2976 servers to our primary router. Affected file silcd/server.c.
2978 * Fixed silc_server_command_identify_check_client to assemble
2979 correct WHOIS packet. It send corrupted WHOIS packet and
2980 caused problem with router to router connections. Affected
2981 file silcd/command.c.
2983 Fixed also silc_server_command_whois_check the same way
2984 as for the IDENTIFY command.
2986 * Added new SilcIDListStatus to the server in the SilcIDListData
2987 structure. The status now includes the current status of
2988 the entry (like registered, resolved etc.). Affected file
2989 silcd/idlist.[ch]. Defined a bunch of different status types
2990 as well. This replaced the old boolean registered field as well.
2992 Added resolve_cmd_ident field to the SilcClientEntry structure
2993 too so that if the entry is for example being resolved so
2994 another command may attach to the same pending command reply
2995 without requiring to resolve the same entry again. This concept
2996 should optimize the WHOIS and the IDENTIFY resolving under
2997 heavy load by taking away unnecessary resolving for entries
2998 that are being resolved already.
3000 Added support for adding multiple pending commands for one
3001 command idenfier. Affected file silcd/command[_reply].[ch].
3003 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3004 before deleting the data. Otherwise the hash table will have
3005 freed data in comparison functions. Affected file is
3006 silcd/command_reply.c.
3008 * Fixed silc_idlist_replace_client_id to add the new entry to
3009 the cache with NULL nickname. Otherwise there will be invalid
3010 memory as the nickname after the nickname is freed. Affected
3011 file silcd/packet_receive.c.
3013 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3014 saved into wrong slots because the previous number of entries
3015 was not taken into account. Affected file silcd/idlist.c.
3016 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3018 * If we are router and we receive JOIN notify to a channel that
3019 does not have any users then notified client is marked as the
3020 channel founder, as it is it. The affected file is
3021 silcd/packet_receive.c
3023 * Added to the extended hash table API's table_del_*ext functions
3024 the destructor as argument too, so that the caller can decide
3025 which destructor to use or whether to use destructor at all.
3026 Affected file lib/silcutil/silchashtable.[ch].
3028 * Fixed ID Cache purging. It actually deleted the entries from
3029 the hash table after the data was freed. The hash table ended
3030 up comparing freed memory. The affected file is
3031 lib/silccore/silcidcache.c.
3033 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Fixed Irssi SILC client's KILL command's HELP syntax.
3037 * The USERS command now resolves the detailed user information
3038 if the userinfo field is missing. Affected file is
3039 lib/silcclient/command_reply.c.
3041 * Do not print error in silc_file_read if the read file does
3042 not exist. Just silently return NULL. Affected file is
3043 lib/silcutil/silcutil.c.
3045 * Fixed the silc_log_output to not wine about NULL filename
3046 and to not create some bogus " " filename. Affected file is
3047 lib/silcutil/silclog.c.
3049 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * Fixed various printing bugs on the user interface in the
3052 Irssi SILC Client. Minor changes that were forgotten from
3055 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Fixed the configure.in.pre and the compilation and distribution
3058 environment to support the new autoconf 2.52. That version is
3059 now required to compile the CVS trunk.
3061 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3064 to generally parse user@fqdn format strings. Affected file
3065 lib/silcutil/silcutil.c.
3067 * Added nickname_format and nickname_force_format fields to the
3068 SilcClientParams structure. The first one defines the format
3069 for the nicknames that the library will enforce if the receives
3070 multiple same nicknames. The second one is boolean value and
3071 can be used to force the library to always enforce the format
3072 to the nicknames regardles whether there are multiple nicknames
3073 or not. This configurable formatting was employed to flexibly
3074 support accessing multiple nicknames from the user interface.
3075 The userinterface can now set the nicknames to what ever format
3076 they prefer. Affected file lib/silcclient/silcapi.h.
3078 Added function silc_client_nickname_format to the file
3079 lib/silcclient/idlist.c. It performs the nickname formatting.
3081 Added new field `hostname´ to the SilcClientEntry context.
3082 It holds the hostname of the client. Affected file is
3083 lib/silcclient/idlist.h.
3085 * Irssi SILC Client sets the nicknames in nick@hostn format.
3086 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3087 irssi/src/silc/core/silc-core.c.
3089 The WHOIS printing now also shows both the real nickname and
3090 the formatted nickname so that user knows how to access the
3091 user if there are multiple same nicknames cached. Affected
3092 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3093 printing formatting too to take the hostname now as a separate
3094 argument. The Affected file is
3095 irssi/src/fe-common/silc/modules-formats.[ch].
3097 * Changed the silc_client_get_clients_local to accept the formatted
3098 nickname as argument. It accepts the real nickname too but the
3099 formatted nickname can be used to find the true entry from
3100 multiple entries. Affected file lib/silcclient/silcapi.h and
3101 lib/silcclient/idlist.c.
3103 * Added nickname_format_parse field to the SilcClientParams.
3104 It is a callback function provided by the application to parse
3105 the nickname out of the formatted nickname string. The library
3106 calls it to get the nickname from the formatted string. Since
3107 the application generally knows better the format of the nickname
3108 string it parses it instead of the library, even though library
3109 encodes the formatted string. If the callback function is not
3110 provided then the library will use the string as is. The
3111 affected file is lib/silcclient/silcapi.h.
3113 * All the nickname strings passed to the client library in
3114 commands are now expected to be formatted nickname strings.
3115 If the command does not support the formatted nickname string
3116 it will assume that the sent string is the actual nickname.
3117 Affected file lib/silcclient/command.c.
3119 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Added public key authentication support to OPER and SILCOPER
3122 commands in the client library. Affected file is
3123 lib/silcclient/command.c.
3125 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Changed the get_auth_methdod client operation to be asynchronous.
3128 It can be async if the application resolves the authentication
3129 method from the server during the negotiation. Added new
3130 SilcGetAuthMeth completion callback that the application will
3131 call after resolving the authentication method.
3133 Added function silc_client_request_authentication_method that
3134 the application can use to resolve the authentication method
3135 from the server. Added also SilcConnectionAuthRequest callback
3136 that the library will call after the server has replied. The
3137 application can call this function if it does not know the
3138 current authentication method.
3140 Affected files are lib/silcclient/client.c and
3141 lib/silcclient/silcapi.h.
3143 * The Irssi SILC client now automatically resolves the authentication
3144 method incase any configuration information is not present (and
3145 currently there never is). The affected file is
3146 irssi/src/silc/core/client_ops.c.
3148 * Fixed public key authentication from the client library.
3149 Affected file lib/silcclient/protocol.c. Changed also the
3150 protocol specification about the public key authentication in
3151 the connection authentication protocol. The actual data to be
3152 signed is now computed with a hash function before signing.
3154 * Fixed the public key authentication from the server as well.
3155 Affected file silcd/protocol.c.
3157 * Removed the mlock()'s from the memory allocation routines.
3158 Affected file lib/silcutil/silcmemory.c. The ./configure does
3159 not check anymore for the mlock(). Affected file is
3162 * Fixed USERS command in server to allow the execution of the
3163 command for private and secret channels if the client sending
3164 the command is on the channel. Affected file silcd/command.c.
3166 * Fixed silc_client_get_clients_local to return the clients
3167 count correctly. It could return wrong value. Affected file
3168 lib/silcclient/idlist.c.
3170 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3172 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3173 types. The assembler optimizations seemed not to like 64-bit
3174 data types. The assmebler optimizations thus are now enabled
3175 also for BSD systems as opposed to only enable them for Linux.
3177 * Do not check for threads at all on BSD systems. Affected
3178 file configure.in.pre.
3180 * Removed -n and -h options from the Irssi SILC Client since
3181 they are not used in silc.
3183 * Fixed the prime generation to assure that the first digit
3184 of the generated random number is not zero since our conversion
3185 routines does not like number strings that starts with zero
3186 digit. If zero digit is seen the random number is regenerated.
3187 This caused some corrupted RSA keys when the zero first digit
3188 was met. Affected file lib/silcmath/silcprimegen.c.
3190 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3192 * Fixed WIN32 configuration in the ./configure script.
3193 Fixed to include xti.h on environments that has it.
3194 Patches by Carsten Ilchmann and andrew.
3196 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3198 * Changed the silc_id_create_client_id to be collision
3199 resistant. It is now assured that there cannot be created
3200 two same client ID's. I suspect that some weird bugs in
3201 the server were actually caused by duplicate Client IDs.
3202 Affected file silcd/serverid.[ch]. A router receiving
3203 new ID now also assures and informs the sending server
3204 if the ID caused collision.
3206 * Changed the silc_id_create_channel_id to also assure that
3207 there are no collisions.
3209 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3211 * Statement about ignoring the Mutual Authentication flag when
3212 performing rekey with PFS was a bit misleading. It is ignored
3213 if it was set in the initial negotiation, it cannot be even
3214 set in the rekey. Fixed in the ke-auth draft. Started the
3215 new versions of the protocol drafts in the doc/.
3217 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Fixed a bug in silc_client_command_identify_save when saving
3220 new channel information. The channel name was no duplicated
3221 and caused crash on exit. Affected file is
3222 lib/silcclient/command_reply.c.
3224 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * Fixed the getkey command handling in the server. Send just
3227 empty OK reply to the sender if the key could not be fetched
3228 (but everything else was ok, like the key just was not available).
3229 Changed the public key parameter to optional in the protocol
3230 specs so that empty OK reply can be sent. Affected file
3233 Added a message to Irssi SILC client to tell to user if the
3234 server did not return a public key.
3236 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Fixed a channel key regeneration bug. It registered new
3239 timeout tasks exponentially until all system resources were
3240 used. Affected file silcd/server.c.
3242 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3244 * Added the SILC Document generator to the scripts/silcdoc.
3245 It can be used to generate the Toolkit Reference Manual out
3246 of the source tree. Internally it will also use the RoboDoc
3247 generator now imported in util/robodoc.
3249 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3251 * Added couple of return's in rekey protocol if error orccurred
3252 during the protocol. The execution must be terminated.
3253 Affected file silcd/protocol.c. Also, terminate the protocol
3254 always with timeout.
3256 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * The client's Client ID was created initally from the wrong
3259 nickname (it could have been in format nick@host) in the
3260 silc_server_new_client. Affected file silcd/packet_receive.c
3262 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Added some SILC_LOG_ERROR's to various error conditions
3265 if client could not be added to ID cache. Affected files
3266 silcd/packet_receive.c and silcd/server.c.
3268 * When client's sock->user_data is freed, NULL also the
3269 client->router and client->connection pointers. Added check
3270 for these pointers being NULL to various places around the
3271 code. Affected file silcd/server.c.
3273 * Added client->data.registered == TRUE checks to various
3274 places around the code to assure that unregistered client's
3275 are not handled when it is not allowed. Affected file
3278 * Added `bool registered' fields to all
3279 silc_idlist_[server|client]_get_* routines to indicate whether
3280 the fetched client needs to be registered or not. Affected
3281 file silcd/idlist.[ch].
3283 * Add your own entry as registered to the ID cache in the
3284 server. Affected file server.c.
3286 * Fixed a bug in silc_server_new_server. The SilcServer was
3287 set as the new server's context instead of SilcServerEntry.
3288 This naturally caused some weird bugs.
3290 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3292 * Do not delete the channel rekey task when adding it
3293 for in silc_server_create_channel_key.
3295 * Changed the silc_server_create_channel_key to return
3296 TRUE or FALSE to indicate the success of the channel key
3299 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Fixed MSVC++ project files and added missing files to
3302 Makefiles under win32/.
3304 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3306 * Do not add TCP_NODELAY flag if the operating system
3307 does not have it defined. Affected files are
3308 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3310 * Fixed buffer overflow from Irssi SILC Client. Affected
3311 file irssi/src/fe-common/core/themes.c.
3313 * Fixed double free in client library in the file
3314 lib/silcclient/client.c when disconnecting from server.
3316 * Applied double free patch from cras to Irssi SILC client.
3317 Affected files irssi/src/core/[modules/expandos].c
3319 * Fixed the disconnection handling to Irssi SILC Client.
3320 The application must call silc_client_close_connection
3321 in ops->connect client operation in case of failure of
3322 the connection. Affected file is
3323 irssi/src/silc/core/client_ops.c.
3325 * Do not set sock->protocol to NULL in the function
3326 silc_client_close_connection after executing the protocol's
3327 final callback since the sock might not be valid anymore.
3328 Affected file lib/silcclient/client.c.
3330 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3332 * Do not enable SILC_THREADS if the linking with libpthread
3333 did not happen. Affected file configure.in.pre.
3335 * Added notion to protocol specification that server must
3336 verify the sent authentication payload with CMODE when
3337 setting the channel founder key. Implemented it to the
3338 server. Affected file silcd/command.c.
3340 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3342 * Added _EXTRA_DIST SILC distribution variable to the
3343 distributions file. It is used to conditionally add extra
3344 files or directories to the specific distribution. Affected
3345 files ./prepare, Makefile.am.pre and distributions.
3347 Removed the `_' from the start of the distribution names.
3350 * Added README.WIN32 for instructions to compile the Toolkit
3353 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Fixed a double free in disconnection in the server. Affected
3356 file is silcd/server.c.
3358 * Fixed the lib/silcske/groups.c to work now also with GMP
3359 MP library. The string conversion did not work when using
3360 specific base and the base is indicated in the string as well.
3362 * Created win32/ directory which now includes MSVC++ specific
3363 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3364 It will appear only in the toolkit distribution
3366 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Changed the key material distribution function in case when
3369 the hash output is too short. The data is now concatenated
3370 a bit differently than it used to. Made the change to the
3371 SKE protocol specification.
3373 * Added better GMP detection to configure.in.pre. A patch
3376 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3378 * Fixed a minor bug in SKE that might cause some problem on
3379 some platforms. Affected file lib/silcske/silcske.c.
3381 * Added the cookie checking for initiator in the SKE. It checks
3382 that the responder returns the sent cookie unmodified. The
3383 affected file is lib/silcske/silcske.c. Added new SKE
3384 error type INVALID_COOKIE that can be sent during the
3385 negotiation. Fixed some memory leaks as well.
3387 * Added the "invalid cookie" error message to Irssi SILC client's
3390 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3392 * Added `task_max' field to the SilcClientParams to indicate
3393 the maximum tasks the scheduler can handle. If set to zero,
3394 default values are used. Affected file lib/silcclient/silcapi.h.
3396 * Fixed memory leaks in silc_client_close_connection. Affected
3397 file lib/silcclient/client.c.
3399 * Added silc_client_del_client_entry to client library to free
3400 all memory of given client entry. Affected file is
3401 lib/silcclient/idlist.[ch].
3403 * Added new functions silc_client_del_channel and
3404 silc_client_del_server to delete channel and server entries.
3405 Affected file lib/silcclient/[silcapi.h/idlist.c].
3407 * Removed silc_client_del_client_by_id from silcapi.h.
3409 * Fixed the INFO command to return the server's own info
3410 correctly when querying by Server ID. Affected file is
3413 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3415 * Removed the non-blocking settings in WIN32 code in the
3416 silc_sock_[read/write] and added SleepEx instead. Affected
3417 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3418 of input data is now checked with FIONREAD and ioctlsocket.
3420 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Call silc_schedule_task_del_by_context in the
3423 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3424 Affected file lib/silccore/silcprotocol.c.
3426 * Call silc_protocol_cancel for active protocols in the
3427 silc_server_close_connection if the funtion
3428 silc_server_free_sock_user_data has not been called.
3429 Affected file silcd/server.c.
3431 * Generic tasks cannot be deleted using the del_by_fd
3432 task deleting function since generic tasks does not match
3433 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3435 * Added a notion to SILCOPER help file that the SILCOPER works
3436 only on router server, not on normal server.
3438 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3440 * Added for WIN32 support for the new scheduler as well.
3441 Affected file lib/silcutil/win32/silcwin32schedule.c.
3443 * Fixed the SHA1 implementation to work on various platforms.
3445 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3448 API. It is part of the scheduler now. Everything else is
3449 as previously but some functions has changed their names.
3450 Checkout the lib/silcutil/silcschedule.h for the interface.
3451 Updated all applications to use the new interface. Affected
3452 files are lib/silcutil/silcschedule.[ch].
3454 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Found a bug in the SKE implementation. The HASH value,
3457 specified by the protocol, was not computed correctly. The
3458 public key of the responder was not added to the computation
3459 even though it is mandatory. Affected file lib/silcske/silcske.c.
3460 This unfortunately causes incompatibilities with older
3461 clients and servers.
3463 * Added WIN32 specific network init and uninit functions:
3464 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3465 the Winsock2. Affected file lib/silcutil/silcnet.h and
3466 lib/silcutil/win32/silcwin32net.c.
3468 * Set the socket always to nonblocking mode on WIN32 after
3469 reading data or writing data. Affected file is
3470 lib/silcutil/win32/silcwin32sockconn.c.
3472 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Fixed various compilation problems under WIN32. Affected
3475 files lib/silcutil/win32/silcwin32thread.c and
3476 lib/silcutil/win32/silcwin32schedule.c.
3478 * Removed all _internal.h #includes from public header
3479 files. Internal headers must never be included from
3482 Removed also the lib/silcske/payload_internal.h file.
3484 * All include files that may be needed (public and some others
3485 included by the public headers) by application developers are
3486 now copied to the ./includes directory. It does not copy any
3487 internal headers. Affected file Makefile.defines.pre and all
3488 Makefile.am's under lib/ and subdirs.
3490 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * Do not change the ~/.silc directory's permissions automatically.
3493 Affected file irssi/src/silc/core/clientutil.c.
3495 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Do not cancel the protocol in silc_server_close_connection
3498 it might cause recursion. Now cancelled in the function
3499 silc_server_free_sock_user_data. Affected file silcd/server.c.
3501 * Fixed the silc_server_remove_clients_by_server to regenerate
3502 the channel keys correctly finally. Added also new function
3503 silc_server_remove_clients_channels to actually do it.
3504 Affected file silcd/server.c.
3506 * Fixed the silc_server_new_channel to not crash by giving
3507 wrong router to the new channel. Affected file is
3508 silcd/packet_receive.c.
3510 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3513 which is given as argument to the silc_client_alloc now.
3514 It can be used to configure the client and set various parameters
3515 that affect the function of the client.
3517 * The USERS command in server did not check whether the channel
3518 is private or secret. Affected file silcd/command.c.
3520 * Added new argument to the USERS command in protocol specification.
3521 The USERS command now can take the channel name as argument
3522 as well. Added support for this in client and server and
3523 updated the protocol specs.
3525 * Completed the GETKEY command in client. It can be now used
3526 to fetch also servers public key not only some clients.
3527 Affected files lib/silcclient/command[_reply].c.
3529 * Added silc_client_get_server to return server entry by the
3530 server name. Affected files lib/silcclient/silcapi.h and
3533 * Redefined the IDENTIFY command in protocol specification to be
3534 more generic. It now can be used to query information about
3535 any entity in the SILC Network, including clients, servers and
3536 channels. The query may be based either the entity's name
3537 or the ID. Added support for this in both client and server.
3539 Affected files silcd/command.c and lib/silcclient/command.c
3540 and command_reply.c.
3542 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3543 the _from_client and _from_server functions. Affected file
3546 * Added silc_client_get_channel_by_id_resolve to the file
3547 lib/silcclient/silcapi.h to resolve channel information by
3548 its ID. Added also silc_client_get_channel_by_id that
3549 does not resolve it from the server.
3551 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Added SilcServerEntry context into the client library
3554 to represent one server. The INFO command now allocates
3555 these to save the resolved server info. For now on the
3556 client library will also keep information about servers,
3557 connected and resolved with INFO.
3559 The INFO command now allocates the SilcServerEntry context
3560 and saves the server info there. The COMMAND_REPLY in
3561 the INFO now returns the parameters to application in
3562 same order as defined in the protocol specification.
3564 The entries are cached in the client->server_cache.
3566 * The INFO command is now issued after received the Client ID
3567 from the server. Affected file lib/silcclient/client.c.
3569 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3570 to the application as the mode changer might be server.
3571 It is guaranteed that NULL is not returned anymore to the
3572 application. Affected file lib/silcclient/client_notify.c.
3574 The ID Type is now also passed to the application so that
3575 it can check whether the returned entry is SilcClientEntry
3578 Added new function silc_client_get_server_by_id to return
3579 the server entry by ID. Affected files are the
3580 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3582 * Do not create the channel in the Irssi SILC Client when issuing
3583 the JOIN command but when received the sucessful JOIN command
3584 reply. Otherwise the channel might get created even though we
3585 could not join it. The Affected file is
3586 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3588 * Fixed a channel joining bug in router. The router must also
3589 check the channel modes, invite and ban lists etc. when serving
3590 the JOIN command sent by normal server. Affected file is
3591 silcd/command.c. The router now resolves the client's
3592 information from the server who sent the JOIN command if it
3593 does not know it, and processes the JOIN command only after
3596 * Changed the SilcCommandCb to take new argument; void *context2.
3597 Affected file lib/silccore/silccommand.h
3599 The second argument in the command callbacks in the server now
3600 includes the SilcServerCommandReplyContext if the command was
3601 called as pending command callback from the command reply.
3602 Otherwise it is NULL. When called as pending the status of the
3603 command reply will be checked and if it was erronous the
3604 error will be sent to the original sender of the command.
3605 This way the client always receives the error messages even
3606 though the server was actually the one who received the error
3607 when it resent the command to router, for example. Affected
3608 files silcd/command[_reply].[ch].
3610 * Fixed sending WHOWAS command's error message to client if
3611 the requested client could not be found. It was missing.
3614 * Changed the CMODE and CUMODE commands reply arguments in the
3615 protocol specification. The Channel ID is now sent in both
3616 of the commands to identify the channel. Implemented this
3617 new feature to the client and server. Affected files
3618 lib/silcclient/command_reply.c and silcd/command.c.
3620 * Made better checks for invite and ban lists in the JOIN
3621 command in server. Affected file silcd/command.c.
3623 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3625 * The server now performs the incoming host IP/DNS lookup
3626 using the silc_socket_host_lookup and thus does not block
3627 the server anymore. Affected file silcd/server.c.
3629 * Completed the multi-thread support for SILC Scheduler in
3630 the lib/silcutil/silcschedule.c.
3632 * Fixed the configure.in.pre to detect the pthread correctly
3635 * Fixed a deadlock in silc_task_queue_wakeup in the file
3636 lib/silcutil/silctask.c.
3638 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3640 * Added new function silc_schedule_wakeup that is used in
3641 multi-threaded environment to wakeup the main thread's
3642 schduler. It needs to be used when a thread adds a new task
3643 or removes a task from task queues. After waking up, the
3644 scheduler will detect the task queue changes. If threads
3645 support is not compiled in this function has no effect.
3646 Implemented the wakeup mechanism to both Unix and WIN32
3647 systems. Affected files are lib/silcutil/silcschedule.[ch],
3648 lib/silcutil/unix/silcunixschedule.c and the
3649 lib/silcutil/win32/silcwin32schedule.c.
3651 * Added new function silc_task_queue_wakeup to wakeup the
3652 scheduler by the specified task queue. Affected file
3653 lib/silcutil/silctask.[ch].
3655 * The silc_socket_host_lookup_start now wakes up the scheduler
3656 after adding the timeout task. Affected file is
3657 lib/silcutil/silcsockconn.c.
3659 * The silc_socket_host_lookup is synchronous now if the threads
3660 support is not compiled in. However, the callback is still
3661 called asyncronously through the scheduler, anyway. Affected
3662 file lib/silcutil/silcsockconn.c.
3664 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3666 * Added new function silc_socket_host_lookup to perform
3667 asynchronous IP and FQDN lookups for the socket connection.
3668 Affected files lib/silcutil/silcsockconn.[ch].
3670 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3673 that may or may not compile the mutex support in.
3675 Changed the silc_mutex_alloc interface. It allocates the
3676 mutex now to the sent pointer and returns TRUE or FALSE.
3678 Affected file lib/silcutil/silcmutex.h.
3680 * Wrote the SILC Task Queue interface to support multi-threads.
3681 Affected file lib/silcutil/silctask.[ch].
3683 * Wrote the SILC Scheduler to support multi-threads. Affected
3684 file lib/silcutil/silcschedule.c.
3686 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3689 in lib/silcutil/win32/.
3691 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Defined SILC Mutex API and SILC Thread API and implemented
3694 them for Unix. Affected files are
3695 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3696 lib/silcutil/unix/silcunixmutex.c and
3697 lib/silcutil/unix/silcunixthread.c.
3699 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Fixed the silc_server_remove_clients_by_server's channel
3702 key re-generation. The hash table handling was incorrect
3703 and would not work with many channels. Affected file is
3706 * Fixed some memory leaks around the server code.
3708 * Rewrote the silc_server_get_users_on_channel to support IPv6
3709 based Client ID's. Affected file silcd/server.c.
3711 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3712 specification. However, a separate document must be written
3713 to define the detailed signing procedure and the payload
3714 associated with the flag. Defined the flag to the
3715 lib/silccore/silcchannel.h as well.
3717 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3719 * Changed the dynamic tables to static size tables in the
3720 lib/silccrypt/silchmac.c.
3722 * Removed GCC dependencies from the code. A patch by cras.
3724 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3726 * Do not show the error "Error receiving packet bla bla"
3727 in server if it really was not an error (-2 means that reading
3728 is pending). Affected file silcd/server.c.
3730 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3732 * Fixed a possible crash in silc_server_remove_clients_by_server
3733 in silcd/server.c. Fixed there also some memory leaks.
3735 * Fixed the silc_idlist_replace_client_id. It could replace
3736 wrong key in the hash table. Affected file silcd/idlist.c.
3738 * Do not check whether there are global users on the channel
3739 if the channel->global_users is FALSE. Affected functions
3740 silc_server_remove_from_one_channel and
3741 silc_server_remove_from_channels in silcd/server.c. Also,
3742 do not check if the removed client is local as we can be
3743 sure that global client was not removed from the channel
3744 and checking for global users is not needed.
3746 * The silc_server_remove_clients_by_server now re-generates
3747 the channel keys correctly for those channels that had
3748 clients removed from them. Affected file silcd/server.c.
3750 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Found the reason of random crashes in the server. We weren't
3753 ignoring the SIGPIPE signal (which can be sent in write())
3754 and it crashed the server. Affected file silcd/silcd.c.
3756 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3758 * Assure that sock->user_data is not NULL in the function
3759 silc_server_packet_send in silcd/packet_send.c.
3761 * Disconnect the remote connection if it could not be added
3762 to any ID lists in the server. The affected file is
3765 * Check in silc_server_packet_send[_real/dest] that the
3766 socket is not disconnecting and ignore the data if it is.
3767 Affected file silcd/packet_send.c.
3769 * Define inline to __inline on native WIN32 compilation.
3770 Affected file includes/silcwin32.h.
3772 * Added some explicit type casts for inline code since MSVC
3773 require them. Affected files lib/silcutil/silcbuffer.h,
3774 lib/trq/silcdlist.h and lib/trq/silclist.h.
3776 * Print warning in log files from now on if the packet
3777 decryption fails. Affected file silcd/server.c.
3779 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3781 * Changed the `say' client operation's interface to accept
3782 new `type' argument to indicate the type of the message sent
3783 by the library. The application may filter the library's
3784 messages according the type. The affected file is the
3785 lib/silcclient/silcapi.h.
3787 * Added two new functions to lib/silcclient/silcapi.h:
3788 silc_client_del_client and silc_client_del_client_by_id.
3789 Affected file lib/silcclient/idlist.c.
3791 * Moved the clientincludes.h from includes/ to silc/ and
3792 serverincludes.h from includes/ to silcd/.
3794 * The modes for the CMODE and CUMODE are now passed as
3795 uint32 for application with COMMAND_REPLY. The affected
3796 file is lib/silcclient/command_reply.c.
3798 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * /WHOIS without arguments shows client's own information.
3801 Affected file lib/silcclient/command.c.
3803 * Changed PING to not accept any arguments. The specs
3804 says that client can ping only the connected server so
3805 requiring an argument is not needed. Affected file is
3806 lib/silcclient/command.c.
3808 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Fixed a fatal bug in private message sending and reception
3811 encryption and decryption when using private message keys.
3812 The implementation was incorrect and did not follow the
3813 specification. It causd that some of the message were
3814 lost since it did not use the sending and receiving keys
3815 as the protocol suggests. This has been fixed and will cause
3816 incompatibilities with older clients when sending private
3817 message encrypted with private message keys. Affected files
3818 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3819 and various other in Irssi SILC Client.
3821 Added `responder' boolean argument to the functions
3822 silc_client_add_private_message_key[_ske] to indicate when
3823 the key is added as responder or initiator of the key
3826 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3828 * Removed the silc_ske_check_version function and created
3829 a SilcSKECheckVersion callback. Added also a function
3830 silc_ske_set_callbacks that is now used to set all SKE
3831 callbacks. The callback functions are not given to
3832 the SKE functions anymore, but this function is used to
3835 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3837 * Added `silc_version' argument to the silc_client_alloc
3838 to define the version of the application for the library.
3839 The library will use the version string to compare it
3840 against the remote host's (usually a server) version
3841 string. Affected file lib/silcclient/silcapi.h
3843 * Added the KE protocol context to Key Agreement context
3844 in client library so that we can abort the SKE if it
3845 is in process when we get timeout. Affected file is
3846 lib/silcclient/client_keyagr.c.
3848 * Do not resolve the client ID forever if it returns in the
3849 first time that such client does not exist. This was done
3850 for example with private message. Affected file is
3851 lib/silcclient/client_prvmsg.c.
3853 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3855 * Do not add regex.h for WIN32. The affected file
3856 includes/silcincludes.h.
3858 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3859 not work yet 100%. It generates the DLL's automatically
3860 when compiling with --with-win32 under cygwin.
3862 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3864 * lib/contrib/regex.c is not compiled on WIN32.
3866 * Added silc_net_get_socket_opt function to the
3867 lib/silcutil/silcnet.h.
3869 * Added includes/silcwin32.h for WIN32 specific includes
3872 * Do not use ptime structure or any of the posix process
3873 functions on WIN32 in lib/silccrypt/silrng.c.
3875 * Added silc_gettimeofday to provide generic function
3876 for struct timeval on all platforms. Added the function
3877 to lib/silcutil/silcutil.h.
3879 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3882 library as they clearly belong there. As a plus side we
3883 can make the actual socket connection routines platform
3886 Added also new generic function silc_socket_read and
3887 silc_socket_write (that used to be silc_packet_[read/write].
3888 The implementation of these are platform specific.
3890 * Added WIN32 specific routines of silc_socket_[read/write]
3891 to lib/silcutil/win32/silcwin32sockconn.c.
3893 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Added preliminary support for native WIN32 compilation under
3896 cygwin (using the -mno-cygwin option for GCC) to the
3897 ./configure.in.pre. The --with-win32 now prepares the
3898 compilation for native WIN32.
3900 * Rewrote the SILC Scheduler interface in the file
3901 lib/silcutil/silcschedule.h. The scheduler is now context
3902 based and does not have anymore any global static scheduler.
3903 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3904 and created lib/silcutil/win32 directory for WIN32 based
3907 * Added Unix specific network routines to the
3908 lib/silcutil/unix/silcunixnet.c and the old
3909 lib/silcutil/silcnet.c includes now only generic routines.
3911 Added WIN32 specific network routines to the
3912 lib/silcutil/win32/silcwin32net.c.
3914 * Added Unix specific utility functions from the
3915 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3917 * Added WIN32 SILC Scheduler to the file
3918 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3921 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3923 * Do not handle JOIN notify in the server if the target client
3924 is not registered (idata->registered == FALSE). The affected
3925 file is silcd/packet_receive.c.
3927 * Update the nickrec->founder in event_cumode in the Irssi SILC
3928 client. Affected file irssi/src/silc/core/silc-channels.c.
3930 * Fixed the CUMODE_CHANGE notify handling in the server when
3931 server and router are announcing their clients on channels.
3932 Now the mode changes are saved and notified correctly. The
3933 affected file is /silcd/packet_receive.c.
3935 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3936 They really did not replace the cache entry in the ID Cache.
3937 Now they do that. Affected file silcd/idlist.c.
3939 * Fixed the KICK notify handling in the Irssi SILC client to
3940 update the channel records so that the kicked client does not
3941 appear to be on the channel. The affected file is
3942 irssi/src/silc/core/silc-channels.c.
3944 * Always update the conn->current_channel when executing command
3945 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3947 * Fixed the KILL notify handling in Irssi SILC client to remove
3948 the killed client on all channels.
3950 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Fixed the silc_parse_command_line to remove extra spaces
3953 from the start and end of the arguments. Affected file is
3954 lib/silcutil/silcutil.c.
3956 * Cancel and free any active protocol in the function
3957 silc_server_close_connection. Affected file silcd/server.c.
3959 * Cancel and free any active protocol in the function
3960 silc_client_close_connction. Affected file is
3961 lib/silcclient/client.c.
3963 * Do not execute the KILL command for clients that are in
3964 history (ie. they are not in the network). Affected file is
3967 * Fixed KILL notify handling, client does not crash anymore.
3968 Affected file irssi/src/silc/core/silc-channels.c.
3970 * Reduced the default packet buffer size from 2048 to 1024 in
3971 lib/silccore/silcpacket.c.
3973 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3974 counter to the SKE context that is incresed when the SKE library
3975 performs async operation outside the library. If the outside
3976 process frees the SKE context and FREED status will be set
3977 and the library will detect after the sync operation that the
3978 libary is freed. The affected files are
3979 lib/silcske/silcske[_status].[ch].
3981 * Resolve the client entry information in the function
3982 silc_client_channel_message to assure that NULL pointer is not
3983 passed as client entry to the application. */
3985 * Fixed the task timeout calculation to assure that there is
3986 never negative timeouts. The affected file is
3987 lib/silcutil/silcschedule.c.
3989 * Fixed the channel user mode notification sending in server.
3990 It was sent point-to-point to the router (or to server by router)
3991 but it needs to be destined to a channel. The routines now
3992 supports sending the channel user mode notifys to the channels
3993 when announcing clients and channels. Affected files are
3994 silcd/server.c and silcd/packet_receive.c.
3996 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3997 It did not actually replace the old channel entry in the cache.
3998 Affected file lib/silcclient/client_notify.c.
4000 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Fixed a possible crash in silc_packet_send_prepare. It now
4003 assures always that there is enough space in the buffer and
4004 at the tail area of the buffer (for MAC).
4006 Fixed the inbound buffer reallocation in silc_packet_read.
4007 It was old code and did not handle the reallocation correctly.
4010 The affected file is lib/silccore/silcpacket.c.
4012 * Fixed buffer overflow in silc_parse_nickname in the file
4013 lib/silcutil/silcutil.c.
4015 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * make install generates new server keys only if there is not
4020 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4023 Added check that if the NOREPLY is set then we will not send
4024 the away message. This avoids infinite loop of away messages
4025 if both clients are away. The affected file is
4026 lib/silcclient/client_prvmsg.c.
4028 * Fixed client crash if /NICK was given without arguments.
4029 Affected file lib/silcclient/command.c.
4031 * Server does not send the invite list in INVITE command back
4032 to the client if the list was not altered. Added this notion
4033 to the protocol spec as well. Affected file silcd/command.c.
4035 Fixed possible crash in INVITE command by checking the
4036 value of silc_server_get_client_route command.
4038 * Fixed the INVITE notify type handling. The arguments are now
4039 taken in correct order and client does not crash. The affected
4040 file is irssi/src/silc/core/silc-channels.c.
4042 Removed the "Inviting xxx to channel" message from the
4043 client library away and let the application handle it.
4044 Affected file lib/silcclient/command.c. Added that message
4045 to Irssi SILC client's message formats.
4047 * Fixed CMODE command crash in client. It now checks the
4048 amount of arguments correctly and does not crash. The affected
4049 file is lib/silcclient/command.c.
4051 * Do not create new channel automatically in silc_channels_join
4052 but check whether the channel by that name already exists.
4053 Affected file irssi/silc/core/silc-channels.c.
4055 * Do not send the SERVER_SIGNOFF to router if the disconnected
4056 entity was the router. Affected file silcd/server.c.
4058 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4059 SILC client as it was missing from there.
4061 Added the handling of the KICK notify to the Irssi SILC client
4062 as it was missing. Added "you have been kicked" message to
4063 Irssi SILC client's message modules formats.
4065 Added the handing of the KILL notify to the Irssi SILC client
4066 as it was missing. Added the kill message module formats
4069 The affected file is irssi/src/silc/core/silc-channels.c.
4071 * The router did not save the channel mode the server announced.
4072 Affected file silcd/packet_receive.c.
4074 * Fixed a possible crash in INFO command in server. If the
4075 server did not provide the server info it crashed. Affected
4076 file silcd/command.c.
4078 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Fixed the GETKEY command in the server to check also the
4081 global list. Otherwise the GETKEY would not work correctly
4082 in normal SILC server. Affected file silcd/command.c.
4084 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Fixed GETKEY crash, it crashed if the command did not succseed.
4088 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4091 is now real and not just an macro interface to GMP.
4093 Removed the entire GMP from the source tree and imported new
4094 NSS MPI library instead. Reason for removing GMP is that it is
4095 extremely large and compiles extremely slow. The NSS MPI
4096 is only a few files and compiles in less than 10 seconds.
4097 The speed is also about the same as GMP. The MPI is imported
4098 to lib/silcmath/mpi.
4100 If the system has GMP installed we will still use the GMP.
4101 If it is not then the NSS MPI will be compiled.
4103 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Merged a long nickname (127 characters long) crash bugfix from
4106 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4108 * Merged a freed memory reference bugfix from Irssi CVS tree.
4109 Affected file irssi/src/core/commands.c.
4111 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Added the server's public key sving and verification to the
4114 server when performing the SKE. This was missing and the
4115 remote server's (or router's) public key was accepted without
4116 checking whether we have it previously or trust it at all.
4117 Affected file silcd/protocol.c.
4119 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Check in the silc_server_timeout_remote if protocol is active
4122 and make sure that the protocol's final callback is called so
4123 that all memory if freed. Affected file silcd/server.c.
4125 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * silc_server_whois_send_reply crashed the server if the nickname
4128 was 127 characters long. Affected file silcd/command.c.
4130 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Added sanity check to the silc_server_new_client. If the hostname
4133 is provided inside username then check that the provided hostname
4134 really is the same as the resolved one. If the hostname was not
4135 resolved then check it from the public key. Affected file is
4136 silcd/packet_receive.c.
4138 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4139 if the server disconnected us and the connection is not valid
4140 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4142 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4143 the library to the lib/silcutil/silcutil.[ch].
4145 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Close log file after open. Affected file
4148 lib/silcutil/silclog.c.
4150 * Check whether sock == NULL in silc_client_send_packet and return
4151 if it is. Affected file lib/silcclient/silcclient.c.
4153 * Check rec->entry == NULL in the Irssi SILC Client before
4154 sending the channel message. Affecte file is
4155 irssi/src/silc/core/silc-servers.c.
4157 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Merged a splitted window bugfix from Irssi CVS tree. The
4160 affected file is irssi/src/fe-text/textbuffer-view.c.
4162 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4163 It did not print nickname.
4165 * Improved the distributions system a bit.
4167 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4170 irssi/src/fe-text/gui-window.c.
4172 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4173 to in-active server. The affected file is
4174 irssi/src/silc/core/client_ops.c.
4176 * Resolve the client in USERS command reply if the entry does
4177 not have username resolved. The affected file is
4178 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4179 command to WHOIS command to really resolve stuff. The USERS
4180 is not used any more in any critical section so WHOIS can
4181 be used even though it might be slower than IDENTIFY.
4183 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4186 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Changed the protocol API a bit more consistent in the
4189 lib/silccore/silcprotocol.[ch].
4191 * Changed the following headers to ROBODoc format:
4193 lib/silccore/silcpayload.h
4194 lib/silccore/silcprotocol.h
4195 lib/silccore/silcsockconn.h
4197 All core library headers are now formatted.
4199 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Fixed a bug in Irssi SILC client; do not show that you are
4202 server/router operator if you really are not. Affected file is
4203 irssi/src/silc/core/client_ops.c.
4205 * Renamed silc_command_free_payload to silc_command_payload_free.
4206 Affected file lib/silccore/silccommand.h
4208 * Added silcmath.h to include the prototoypes of various routines
4209 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4212 * Changed the following headers to ROBODoc format:
4214 lib/silccore/silcchannel.h
4215 lib/silccore/silccommand.h
4216 lib/silccore/silcid.h
4217 lib/silccore/silcidcache.h
4218 lib/silccore/silcmode.h
4219 lib/silccore/silcnotify.h
4220 lib/silccore/silcpacket.h
4221 lib/silcmath/silcmath.h
4223 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Added checking to the server code not to start the server if
4226 ciphers and stuff are not configured properly. Affected files
4227 silcd/serverconfig.[h] and silcd/server.c.
4229 * Changed the layout of the header files of the public interfaces
4230 in the SILC libraries. The new layout supports ROBODoc
4231 documentation tool (and some others) so that it is easy to create
4232 a library reference manual. All the other headers and source
4233 code must still follow the CodingStyle document. Also source
4234 code must not include these ROBODoc stuffs, only the headers.
4235 Furthermore, all public interface headers must now be named
4236 by using `silc' prefix, example: silcapi.h, silccipher.h.
4237 Some files were renamed due to this. All the other headers
4238 must not be used as public interfaces. I will update the
4239 CodingStyle document later. Changed following headers, so far:
4241 lib/silcclient/silcapi.h
4242 lib/silccore/silcauth.h
4243 lib/silccore/silcprivate.h
4244 lib/silccrypt/silcdh.h
4246 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Removed silc_client_packet_send_flush from the client library
4251 as it is not needed. Affected file lib/silcclient/client.[ch].
4253 * Added printing of message of unresolved authentication method
4254 to the Irssi SILC client. Added it to the module formats.
4255 Removed the same message from the client library.
4257 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Added new distribution feature, DISTLABEL. Every distribution
4260 can define own preprocessor label that can be used in the
4261 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4262 file distributions, acconfig.h.pre and prepare.
4264 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Added Makefile.defines_int to include the actual definitions
4267 for Makefile.defines.in. Tested the new distribution system,
4268 created distributions and tested installation.
4270 * Added AWAY message printing to the Irssi SILC client. Added
4271 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4273 * Added SCONNECT command to call the SILC's CONNECT command.
4274 Cannot use CONNECT directly since Irssi uses that internally.
4275 Affected file irssi/src/silc/core/silc-servers.c.
4277 Added ACTION local command. It is same as ME command but takes
4278 the channel as mandatory argument.
4280 Rewrote some of the Irssi's help files to suite for SILC
4283 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added Makefile.defines[.in] that should for now on be included
4286 in all Makefile.am file in the source tree. That file includes
4287 all common compilation definitions for SILC source tree.
4289 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Minor changes to the ./prepare script to change the package
4292 name according the distribution name to the configure.in.
4294 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Created new distribution system. Added file `distributions'
4297 that defines all the distributions that can be created out of
4298 the SILC source tree. The ./prepare script now reads that
4299 file to determine how to prepare the distributions. The
4300 first argument to the ./prepare is the name of the distribution
4301 and second is the version of the distribution. If given
4302 without arguments it creates the default (toolkit) distribution
4303 with the default version (defined in ./prepare).
4305 All Makefile.am files that are subject to the distributions
4306 are now named as Makefile.am.pre. These are ./Makefile.am
4307 and lib/Makefile.am. Others may be changed later.
4309 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Added invite list, ban list, some key management and connection
4312 error message printing to module formats in the Irssi SILC client.
4314 * Added new silc_client_set_away_message to set the away message
4315 that is back to the person who sent private message. The
4316 affected file lib/silcclient/silcapi.h and the
4317 lib/silcclient/client_prvmsg.c.
4319 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Fixed the private message sending in the Irssi SILC client,
4322 added local command KEY to the Irssi SILC client.
4324 Added key management and key agreement message formats to the
4325 irssi/src/fe-common/silc/module-formats.[ch].
4327 Added USERS (alias WHO) printing, server/router operator
4328 indication and LIST command printing to the module formats.
4330 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Fixed channel joining notify handling, cumode notify handling
4333 from Irssi SILC client.
4335 * Added SILC specific module-formats to the Irssi SILC client so
4336 that SILC specific message hilighting, colors etc is possible.
4337 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4339 Added channel mode, channel user mode, actions, notices,
4340 whois and whowas printing to the the module-formats.c.
4342 * Fixed a bug in channel deletion in the server. The channel
4343 is not left to the cache even if the channel founder auth mode
4344 is set when there are no users anymore on the channel. Affected
4345 file silcd/server.c.
4347 * The silc_net_localhost now resolves the entire hostname including
4348 the domain name. Affected file lib/silcutil/silcnet.c.
4350 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4352 * Changed the ask_passphrase client operation to be ascynchronous.
4353 It has now a completion callback and a context that the
4354 application must call after it has got the passphrase from
4355 the user. Affected files lib/silcclient/silcapi.h,
4356 lib/silcclient/protocol.c, lib/silcclient/command.c and
4359 Added SilcAskPassphrase callback that the application calls
4360 to deliver the passphrase to the library.
4362 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4363 The public key verification and especially a certificate
4364 verification is asynchronous procedure.
4366 Added new SILC_SKE_STATUS_PENDING status to indicate the
4367 request is pending and a callback will be called to finalize
4370 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4371 indicate that remote end did not send its public key (or
4372 certificate), even though we require it. Added check for this
4373 condition in the SKE. This was a security bug, now fixed.
4375 Defined new SilcSKEVerifyCbCompletion callback that is called
4376 when the verification process is completed.
4378 The affected files lib/silcske/silcske_status.h and
4379 lib/silcske/silcske.[ch].
4381 * Changed the verify_public_key client operation to be async
4382 as well. Defined SilcVerifyPublicKey callback that is used to
4383 indicate the success of the public key verification process.
4385 Changed the server and client to use the new async client
4388 * Changed the Irssi SILC client's internal scheduler to be called
4389 twice as many times as it used to be. As a result the client
4390 should be a bit faster now. Affected file is
4391 irssi/src/silc/core/silc-core.c.
4393 * Added support to Irssi SILC client of asynchronous public key
4394 verification and passphrase inquiry. Affected file is
4395 irssi/src/silc/core/silc-core.c.
4397 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Do not say "You have left channel %s" in client library.
4400 Moved it to the application. Affected files are
4401 lib/silcclient/command.c and silc/client_ops.c.
4403 * Fixed silc_client_get_clients. Command context was not
4404 duplicated and was freed memory in the callback. Affected
4405 file lib/silcclient/idlist.c.
4407 * Do not say "you are now talking..." on JOIN command in the
4408 client library. The appliation must handle it.
4410 * Do not say ".. changed topic to" in command reply in the
4411 client libary. The application must handle it.
4413 * Fixed TOPIC command sending in the client library.
4415 * Fixed a memory leak in silc_client_command_free in the file
4416 lib/silcclient/command.c.
4418 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Imported a modified version of Irssi client to the source tree.
4421 The Irssi will be used to create a new client called
4422 Irssi SILC. Imported to irssi/.
4424 Added silc_core_init_finish function to the Irssi. Affected
4425 file irssi/configure.in.
4427 A lot changes in the Makefile.ams around the irssi tree.
4429 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Do not rehash if the new size is same as the old size of the
4432 hash table, in the silc_hash_table_rehash*. The affected file
4433 lib/silcutil/silchashtable.c.
4435 * Replaced hash_table_del_by_context calls from the server
4436 (when channel->user_list and client->channels) to the
4437 hash_table_del as it is sufficient and faster.
4439 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Added silc_hash_table_list, silc_hash_table_get and the
4442 SilcHashTableList structure to provide an alternative way to
4443 traverse the hash table. The affected files are
4444 lib/silcutil/silchashtable.[ch].
4446 * Changed the server's idlist routines to use the hash table
4447 routines to optimize the code.
4449 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Replaced the client entry's `channel' list and channel entry's
4452 `user_list' list to hash tables for optimized lookup. Changed
4453 the code to use the hash table interface around the code.
4454 Affected file lib/silcd/idlist.[ch].
4456 * Added `auto_rehash' boolean argument to the function
4457 silc_hash_table_alloc to indicate whether the hash table should
4458 auto-rehash when it thinks is appropriate time. It will
4459 increase the hash table size if the there is twice as much
4460 entries in the table than the size of the table, and will
4461 decrease the size if there are twice as less entries than
4462 the size of the table.
4464 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4468 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * silc_idcache_purge_by_context deletes the entry now by context
4471 as it is supposed to do. Affected file lib/silccore/idcache.c.
4473 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4474 client is not anymore valid (WHOWAS givens the info) and not
4475 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4477 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Removed the `data' and `data_len' arguments from the ID Cache
4480 interfaces and added `name' argument. ID Cache does not handle
4481 anymore the binary data only a names associated with given ID.
4483 * When hashing a Client ID with silc_hash_id the entire ID is
4484 not hashed anymore, instead only the hash of the Client ID is
4485 hashed. This way we can access the Client ID from the cache
4486 with Client ID but with the hash of the ID (which is a hash of
4487 the nickname) as well without any difference in performance.
4489 Added also silc_idcache_find_by_id_one_ext to do one on one
4490 searching when we have the actual ID. Added also function
4491 silc_hash_client_id_compare. The affected files are
4492 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4494 * When hashing the name associated with a ID it is always done
4495 in lowercase. This way we can access the cache without worrying
4496 about case-sensitivity, even though, for example nicknames are
4499 * Fixed a bug in server with channel message sending. It put
4500 wrong ID type as destination ID. The affected file
4501 silcd/packet_send.c.
4503 * silc_idcache_del_by_context now deletes from all hash tables
4504 by context. Affected file lib/silccore/idcache.c.
4506 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Changed the client library to use the new ID Cache interface.
4509 Changes around the source tree.
4511 * Added silc_hash_table_rehash_ext to rehash with specific
4512 hash function. Affected file lib/silcutil/silchashtable.[ch].
4514 * Added silc_hash_string_compare to compare two strings in the
4515 hash table. Affected file lib/silcutil/silcutil.[ch].
4517 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Added new function silc_idcache_del_by_context into the
4520 lib/silccore/idcache.[ch].
4522 * Changed the server's ID list routines to use the new ID Cache
4523 interface. Changes around the source tree.
4525 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added silc_hash_table_del[_by_context]_ext functions in to the
4528 lib/silcutil/silchashtable.[ch].
4530 Removed silc_hash_table_find_all* routines and added new
4531 silc_hash_table_find_foreach to replace them.
4533 Added silc_hash_table_replace_ext function as extended
4534 replacing function. Separated the simple hash table interface
4535 from the extended hash table interface in the file
4536 lib/silcutil/silchashtable.h.
4538 * Fixed minor bugs and changed it to use some of the new
4539 hash table functions in lib/silccore/idcache.c
4541 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Added new function silc_hash_table_find_all to return all keys
4544 in the hash table by the specified key. As the hash table is
4545 collision resistant it also makes it possible to have several
4546 duplicate keys in the hash table. This function may be used to
4547 find all of the keys from the hash.
4549 Added user_context arguments to the SilcHashFunction,
4550 SilcHashCompare and SilcHashDestructor to deliver user specified
4553 Added new fuctions silc_hash_table_find[_all]_ext to do
4554 extended lookup with specified hash and compare functions and
4555 specified user contexts.
4557 Added new function silc_hash_table_add_ext to add the key
4558 with specified hash function and user context.
4560 Added new function silc_hash_table_foreach to traverse all
4561 entrys in the hash table. Added SilcHashForeach callback
4564 Added new function silc_hash_table_del_by_context to delete
4565 the entry only if the context associated with the key matches.
4567 Affected files are lib/silcutil/silchashtable.[ch].
4569 * Removed silc_hash_[server/client/channel]_id and added just
4570 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4571 silc_hash_id_compare to compare two ID's using as the hash table
4572 comparison function. Added also silc_hash_data to hash
4573 binary data and silc_hash_data_compare to compare it.
4575 * Removed silc_idlist_find_client_by_hash as it is not needed
4576 anymore. Affected file silcd/idlist.[ch].
4578 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4579 to use internally the SilcHashTable. The new ID Cache is a lot
4580 faster than the old one. Some of the ID Cache interface was also
4581 rewritten and obsolete and stupid functions were removed.
4583 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Added entry_count field to the SilcHashTable to keep the number
4586 of the entries in the table. Implemented the function
4587 silc_hash_table_rehash. Added new function
4588 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4590 Fixed a minor bug in silc_hash_table_free.
4592 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4593 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4594 into the lib/silcutil/silcutil.[ch].
4596 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Implemented a collision resistant hash table into the
4599 lib/silcutil/silchashtable[ch]. See the header and the source
4600 for the SilcHashTable API.
4602 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Merged dotconf version 1.0.2 into lib/dotconf.
4606 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Do not compile anything in lib/silcsim/* if the SIM support
4609 is not enabled. The tree should now compile without problems
4612 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Compiled the SILC under cygwin. Compiled and tested briefly
4615 without problems. More tests needed. The SIMs didn't compile
4618 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4620 * Fixed possible crash in silc_get_username in the
4621 lib/silcutil/silcutil.c.
4623 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Fixed a va_arg in silc/client_ops.c.
4627 * Oops, RC5 routines were named AES and caused some problems
4628 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4630 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Added new SilcIDIP structure into the lib/silccore/id.h and
4633 replaced the old `ip' fields from all SILC ID's to that type.
4634 This is a step towards IPv6 support.
4636 The silc_id_get_len takes now the ID as an extra argument.
4637 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4638 both IPv4 and IPv6 based ID's.
4640 The affected files are lib/silccore/id.[ch] and other files
4641 around the tree using these routines.
4643 * Removed the ID length arguments in server from various
4644 silc_server_send_notify_* routines -> they are not needed
4647 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Fixed memory leak in silc_encode_pem_file in the file
4650 lib/silcutil/silcutil.c.
4652 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Check minor version as well in the SKE. Affected files are
4655 silcd/protocol.c and lib/silcclient/protocol.c.
4657 * Added --identifier option to the server so that an identifier
4658 can be when creating the public key for the server. Affected
4659 file is silcd/silcd.c.
4661 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4662 lib/silccrypt/silcpkcs.c.
4664 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Register default ciphers and stuff when using -C option with
4667 the server. Affected file sildc/silcd.c.
4669 * Put back the servers public key filename format, it is better
4670 than the new one. For now, the client keys are saved with the
4671 new filename format. The affected file silc/client_ops.c.
4673 * Implemented the Cipher API for the rest of the ciphers that
4674 did not implement it or implemented it the wrong way.
4676 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Register default ciphers and stuff when using the -S option
4679 in the client. Affected file silc/silc.c. Same also when
4680 creating new key pair with -C option.
4682 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Fixed the silc_verify_public_key client operation function to
4685 save the public keys differently. The fingerprint is now
4686 used as filename and not the hostname. This way also the
4687 client keys are saved uniquely and not with hostnames. The
4688 affected file is silc/client_ops.c.
4690 * Trimmed the silc_hash_fingerprint function to remove extra
4691 whitespaces from the end of the fingerprint. The affected
4692 file is lib/silccrypt/silchash.c.
4696 * Added silc_cipher_register_default function to register all
4697 default ciphers. It can be used when configuration files
4698 does not exist and the application does not want any specific
4699 ciphers in any specific order.
4701 The SilcDList is now used as silc_cipher_list dynamically
4702 allocated cipher list. Removed the static list all together
4703 and now all ciphers must be allocated to the dynamic list.
4704 The silc_cipher_alloc routine was changed to check only the
4707 All silc_cipher_* routines that used to return int returns
4710 The affected files lib/silccrypt/silccrypt.[ch].
4712 * The same thing was done to silc_hash_* as for silc_cipher_*
4713 routines. Affected files lib/silccrypt/silchash.[ch].
4715 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4716 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4717 Added also silc_pkcs_[un]register[_default] functions.
4718 Removed the data_context from the PKCS API.
4720 * Added silc_hmac_register_default function to register default
4721 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4722 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4723 to unregister all hmacs at once.
4725 * Register the default ciphers, hash functions, PKCSs and HMACs
4726 if client's configuration file does not exist. The affected
4729 * The client did not load the hash functions from the SIM
4730 modules at all. Added support for this. Affected file is
4731 silc/clientconfig.c.
4733 * When decoding public key with silc_pkcs_public_key_decode, check
4734 the supported algorithm only if PKCS are registered. Affected
4735 file lib/silccrypt/silcpkcs.c. The same was done with the
4736 silc_pkcs_private_key_decode.
4738 * Fixed the SILC List routines to keep the list always in order.
4739 It used to change the list's order when traversing the list but
4740 not it preserves the order. Affected file lib/trq/silclist.h.
4742 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added the client library to use the SilcSocketConnection's
4745 reference counter (by silc_socket_dup) to prevent the bug that
4746 the socket object may be freed underneath async operation.
4748 * The name resolv library checking fixes in the configure.in.pre.
4751 * Created new version of the protocol drafts for future
4752 development. The -03 drafts are the ones that will be changed
4753 in the trunk now and the -02 will remain as they are.
4755 * Send list of CUMODE notifys to the router when announcing
4756 the channel users to the router. Affected file silcd/server.c.
4757 If the router receiving channel founder CUMODE for a channel
4758 that already has channel founder it will send CUMODE notify
4759 to the sender to remove the channel founder rights from the
4760 announced client. Affected file silcd/packet_receive.c.
4762 * The CUMODE notify may now use Server ID as well as the entity
4763 who changes the mode. Updated protocool specs.
4765 * Updated INSTALL and README files.
4767 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * New web pages in the http://silc.pspt.fi. The pages was
4774 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Implemented the [DenyConnectin] config section in the server.
4777 Added silc_server_config_denied_conn to check whether incoming
4778 connection is denied. Affected file silcd/serverconfig.[ch].
4780 * Do not check the ports when checking the incoming configuration
4781 data if the port is 0, meaning any. Affected file is
4782 silcd/serverconfig.c.
4784 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Fixed buffer overflow in silc_string_compare in the file
4787 lib/silcutil/silcutil.c.
4789 * Fixed double free in silc_server_command_leave in the file
4792 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Fixed the version checking in the server. Affected file is
4797 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Fixed the configuration data fetching when accepting new
4800 connections in the server. Affected file silcd/server.c.
4802 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Added `sender_entry' argument to the function
4805 silc_server_packet_relay_to_channel so that we can check
4806 whether some destination actually belongs to the same route
4807 the sender belongs (ie, we must not resend the packet to the
4808 sender). Affected file silcd/packet_send.[ch].
4810 * Added `servername' field to the SilcClientEntry in the server
4811 to hold the name of the server where client is from. Affected
4812 file is silcd/idlist.h.
4814 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Moved the channel message encrypting in the router betwen
4817 router connections from silc_server_channel_message to the
4818 silc_server_packet_relay_to_channel since we want to check
4819 whether we have anybody channel before encrypting anything.
4820 Affected files silcd/packet_[receive/send].c.
4822 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Fixed the [AdminConnection] server config section to support
4825 multiple entries. Affected file silcd/serverconfig.c.
4827 * Added support into the server to check the validity of the
4828 incoming connection before executing any KE or authentication
4831 * The connection configuration is now saved to the KE and
4832 connection auth protocol contexts and not fetched anymore in
4833 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4835 * The local hosts listenning address and port is also resolved
4836 now when starting the server. We want to have the socket object
4837 to include the real address and port for the listener. Added
4838 new function silc_net_check_local_by_sock into the files
4839 lib/silcutil/silcnet.[ch].
4841 * Fixed a broadcast bug in server -> do not broadcast if we
4844 * Fixed a routing bug. Do not route broadcast packets ever.
4845 Broadcast packets must be processed always and not routed since
4846 they may be destined to some other host than yourself and thus
4847 would get routed without no good reason. Affected file is
4850 * Added function silc_server_config_is_primary_route to check
4851 whether primary router connection has been configured (a router
4852 configuration that we are initiating). If there is not, we
4853 will assume that there is only two routers in the SILC network
4854 and we will use the incoming router connection as our primary
4855 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4857 * Changed the order of the broadcasting. Broadcast _after_ the
4858 packet has been processed not before. Affected file is
4861 * Fixed a [ClientConnection] parsing bug. The port was never
4862 parsed correctly thus resulting to port 0. Affected file
4863 silcd/serverconfig.c.
4865 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4866 argument and did not set the broadcast packet flag. Affected
4867 file silcd/packet_send.c. Fixed same bug in the function
4868 silc_server_send_notify as well.
4870 * If we receive NEW_ID packet for our own ID in the server, ignore
4873 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Removed the nickname from the Private Message Payload.
4878 Updated the code and the protocol specs.
4880 * Updated protocol specs for submitting to the IETF.
4882 * Tweaked the Random Number Generator a bit. Affected file
4883 lib/silccrypt/silcrng.c. Exported a new function
4884 silc_rng_[global]_add_noise which can be used to add more
4887 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Do not parse packets with different timeout when protocol
4890 is active -> may cause problem with rekey. Affected file
4893 * When server receives signoff notify it must not create
4894 new channel key if the client is on any channels since the
4895 sender of the signoff notify will create it.
4897 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added printing of error messages during SKE protocol from the
4900 failure packet sent by server during SKE. Affected file
4903 * Removed the client's failure_callback handling with timeout
4904 and handle it immediately when received.
4906 * The SKE library returned wrong type in SUCCESS and FAILURE
4907 packets. They must be 32 bit MSB not 16 bit MSB.
4909 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Ok, rewrote the logic of the re-key and now it seems to work.
4912 I tested it on high traffic with frequent re-keys without
4913 problems. Added hmac_receive (and renamed hmac to hmac_send)
4914 in SilcClientConnection in lib/silcclient/client.h and
4915 in SilcIDListData in silcd/idlist.h. Also, removed the
4916 SilcPacketParserContext's cipher and hmac fields as they are
4917 not needed anymore and actually caused some problems when
4918 the ciphers and hmac's changed underneath the packet parser.
4920 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * If re-key protocol is active then process the incoming packets
4923 synchronously since we must assure that icoming packets encrypted
4924 with the old key is processed before the new keys is set to
4925 use. This is true other packets than for REKEY packets.
4926 Affected file silcd/server.c. The same was done to client library
4927 as well, affected file lib/silcclient/client.c.
4929 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Fixed bug in client and server to accept the force send if
4932 the packet is send from silc_[server/client]_packet_process
4933 function. Otherwise the packets are never delivered, oops.
4935 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Disable force sending of packets when REKEY protocol is active.
4938 We must assure that no packet is sent directly when rekey is
4939 performed. All packets must be sent through packet queue.
4940 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4941 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4942 function is silc_[server/client]_packet_send_real to check
4945 * Replaced the SIM paths from example config files to
4946 /usr/local/modules. Also, make install creates now
4947 /usr/local/silc/logs directory to hold all the SILC server
4950 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Made the configure.in.pre work on Solaris. Patch by salo.
4954 * Made all ciphers compatible with non-x86 machines. Defined
4955 CBC mode macros into lib/silccrypt/ciphers_def.h.
4957 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Fixed the make install.
4961 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * When MAC computation fails the silc_packet_decrypt returned 0
4964 even though it was supposed to return -1. Fixed this. The
4965 affected file is lib/silccore/silcpacket.c.
4967 * Do not replace the config files in /etc/silc (in make install)
4968 if they already exist. Affected file ./Makefile.am.
4970 * Do not send re-key packets immediately but through packet queue.
4971 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4973 * Changed silc_net_check_host_by_sock to return FALSE if the
4974 IP/DNS could not be resolved. Though, it returns the IP address
4975 now even if it could not resolve it (but returns also FALSE).
4976 Affected file lib/silcutil/silcnet.[ch].
4978 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Added silc_pkcs_decode_identifier to decode the public key's
4981 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4982 Added also silc_pkcs_free_identifier. Added also new context
4983 SilcPublicKeyIdentifier.
4985 * Added -S option to the silc client. It is used to dump the
4986 contents of the specified public key file.
4988 * Changed the PKCS api to return the public key length when
4989 setting the public key.
4991 * Fixed a fatal bug in the public and private key file loading.
4992 Affected file lib/silccrypt/silcpkcs.c.
4994 * Execute the packet parsing for client with zero (0) timeout
4995 if the protocol is active. Affected file silcd/server.c.
4997 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Made the key generation options to the silcd program. Added
5000 -C option, equivalent to client's option.
5002 * Added new [ServerKeys] config section to the server. It
5003 configures the server's public and private key.
5005 * Defined generic Public Key Payload into the protocol
5006 specification to send specific type of public keys and
5009 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5010 public key or certificate.
5012 * Implemented the GETKEY command to the server and to the
5013 client library and on user interface.
5015 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Made preliminary `make install' work.
5019 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Added SilcServerRekey context into silcd/idlist.h.
5023 * Added the PFS support as defined in the specification to the
5024 SKE protocol. Affected files lib/silcske/*.c.
5026 * Added `ske_group' field to the SilcServerRekey context to hold
5027 the number of the SKE group that is used with PFS in re-key.
5028 Affected file silcd/idlist.h.
5030 * Added PFS re-key support to the server. Affected file is
5033 * Added silc_protocol_cancel to cancel execution of the next
5034 state of the protocol. Affected file is
5035 lib/silccore/silcprotocol.[ch].
5037 * Added the re-key support with and without PFS to the client
5038 library. Re-key is performed once in an hour, by default.
5040 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5041 Added silc_client_rekey_callback and silc_client_rekey_final.
5042 Affected files are lib/silcclient/protocol.[ch] and
5043 lib/silcclient/client.[ch].
5045 * Removed the `hmac_key' and `hmac_key_len' fields from the
5046 SilcClientConnection structure; not needed. Affected file is
5047 lib/silcclient/client.h.
5051 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Do not ask whether user wants to use the negotiated private key
5054 for private messages, just use it. Affected file is
5055 silc/local_command.c.
5057 * Added `send_enc_key' and `enc_key_len' fields to the
5058 SilcIDListData structure since they are needed in the re-key
5059 phase. Affected file is silcd/idlist.[ch].
5061 * Implemented the simple re-key protocol into the server.
5062 Affected files silcd/server.c and silcd/protocol.[ch]. The
5063 re-key will be performed once in an hour, by default.
5065 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5066 Added silc_server_rekey, silc_server_rekey_callback and
5067 silc_server_rekey_final.
5069 * Removed Tunneled flag from the protocol. Updated the code
5070 and the specifications.
5072 * Adde `pfs' field to the SilcIDListData to indicate whether
5073 the PFS is to be performed in the re-key. Affected file is
5076 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5079 int64 of at least the xintXX size. If void * is less that 4
5080 bytes uint32 * will be used. Defined bool as boolean.
5082 * Changed _ALL_ unsigned long and unsigned int to uint32,
5083 unsgined short to uint16 in the source tree.
5085 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5086 not handle clients that has entry->data.registered == FALSE.
5087 They are not in the network anymore. Affected file is
5090 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Implemented the sending of the SERVER_SIGNOFF notify in the
5093 server. Affected file is silcd/server.c.
5095 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5096 Added also silc_notify_payload_encode_args into the
5097 lib/silccore/silcnotify.[ch].
5099 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5100 Affected file silcd/packet_receive.c.
5102 * Implemented the SERVER_SIGNOFF notify handling in the client
5103 library. Affected file lib/silcclient/client_notify.c. Also,
5104 implemnted the printing of the SERVER_SIGNOFF info to the
5105 application. Affected file silc/client_ops.c.
5107 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5108 if the deleting was successful. Affected file silcd/idlist.[ch].
5110 * Added support for public key authentication in the connection
5111 authentication protocol in the client library. Affected file
5112 lib/silcclient/protocol.c.
5114 * Changed the server's silc_idlist_get_clients_by_* interface
5115 to support already allocated array so that new entries may be
5116 added to pre-allocated array. Affected file silcd/idlist.[ch].
5117 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5118 and command replies.
5120 * All command reply functions in the server now calls the
5121 pending command callback even if error occured. This way the
5122 error will be delivered to the client as well. Affected files
5123 silcd/command.c and silcd/command_reply.c.
5125 * Fixed INFO command to return local server's info if no server
5126 was provided. Affected file lib/silcclient/command.c.
5128 * Removed RESTART command for good. Updated the code and the
5131 * Rewrote parts of the task system. It is a bit simpler now.
5132 Removed unsued task priorities. The affected files are
5133 lib/silcutil/silctask.[ch].
5135 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Moved the USERS printing from the library to the application.
5138 Affected files lib/silcclient/command.c and silc/client_ops.c.
5140 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added channel key re-key support. The re-key is perfomed
5145 only by the router and is done once in an hour. Added `rekey'
5146 field to the SilcChannelEntry in the server. Affected files
5147 silcd/server.c and silcd/idlist.h.
5149 * Added silc_task_unregister_by_context into the file
5150 lib/silcutil/silctask.[ch].
5152 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Added SILC_UMODE_GONE mode to indicate when the client is not
5155 present in the SILC network. Added also support to the local
5156 command AWAY that will set this mode. Added support of showing
5157 "xxx is gone" in WHOIS command. The USERS command shows the
5158 gone status as well.
5160 * Fixed setting server and router operator privileges in the
5161 server's UMODE command. Affected file silcd/command.c.
5163 * Merged the SKE KE1 and KE2 payloads into one payload. The
5164 new KE payload is equivalent to the old KE2 payload.
5166 Cleaned up the SKE Start Payload parsing. It now uses the
5167 simple buffer unformatting to do the parsing. A lot faster
5170 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5171 to the SKE that is used to indicate whether both of the SKE
5172 parties should perform authentication. By default only the
5173 responder performs authentication. By setting this flag also
5174 the initiator must do authentication. By default it is unset
5175 since in normal SKE case, client to server connection, only
5176 the responder should do authentication. When doing SKE between
5177 two clients both should perform authentication. Updated the
5178 code and the protocol specs.
5180 * A little fix to IDENTIFY command in the server. Search the
5181 client first by hash not nickname. Affected file is
5184 * Fixed the silc_client_close_connection to support closing
5185 the client to client connections wihtout deleting too much
5186 data. Affected file lib/silcclient/client.c.
5188 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5189 are received if protocol used to be active but is not anymore
5190 the application would crash due to NULL pointer dereference.
5191 Affected files silcd/server.c and lib/silcclient/client.c.
5193 * Added `hash' field to the SilcClientConnection to include
5194 the hash function negotiated in the SKE protocol.
5196 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5197 to set the channel founder authentication data. A client can
5198 claim the founder rights later by providing the authentication
5199 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5200 This way the channel founder can regain the channel founder
5201 privileges even it is left the channel. This works only on
5202 local server and the client must be connected to the same
5203 server to be able to regain the founder rights. Updated the
5204 protocol specs accordingly.
5206 Added support to the CMODE command in the client to set the
5207 founder auth data. Read the README to see how to set it.
5209 Added support to the CUMODE command to claim the founder
5210 rights. Read the README to see how to do it.
5212 Added support for the founder authentication to the Channel
5213 Entry in the server. Affected file silcd/idlist.h.
5215 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5216 server's CMODE command. Affected file silcd/command.c.
5218 * Added the following new functions into lib/silccore/silcauth.[ch]:
5219 silc_auth_get_method and silc_auth_get_data.
5221 * The server now saves the remote hosts public key to the
5222 SilcIDListData pointer. Affected file silcd/protocol.c.
5224 * The normal server now does not remove the channel entry from
5225 the cache if the founder authentication data is set. It used
5226 to remove it if the founder was the last one on the channel on
5227 the server and left the channel. The auth data is saved and
5228 if the channel is re-joined later the old entry is used with
5229 the old auth data. Affected files silcd/command_reply.c and
5232 * Removed the `pkcs' field from the SilcIDListData structure
5233 in the server; it is not used. Affected file silcd/idlist.h.
5235 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Fixed packet processing on slow links. Partial packets were
5238 never re-processed because the incoming data buffer was cleared
5239 by the application. Application must not directly clear the
5240 sock->inbuf, the packet processing routines handle it. Fixed
5241 this in client library and in server.
5243 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Fixed the WHOIS and IDENTIFY send reply function to really
5246 check whether to send list or just one entry. Affected file
5249 * Cleaned up the LEAVE command's channel key distribution. The
5250 affected file silcd/command.c.
5252 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5253 can enforce the channel mode as well. In that case the ID
5254 includes the ID of the server. The code now enforces the
5255 mode change if the router have different mode than the server.
5257 * The notify client operation with CMODE_CHANGE notify can now
5258 return NULL client_entry pointer if the CMODE was not changed
5259 by client. Application must check for this.
5261 * Added <Server ID> argument to INFO command to support server
5262 info fetching by Server ID.
5264 * Added silc_server_announce_get_channel_users to get assembled
5265 packets of channel users of the specified channel. Affected
5266 file silcd/server.[ch].
5268 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5269 was freed underneath the ID Cache.
5271 * Re-announce clients when the server received CHANNEL_CHANGE
5272 notify from the router. Affected file silcd/packet_send.c.
5274 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5277 crashed since it did not handle the fact that there is no cipher
5278 called "3" and didn't check the error condition. Now fixed.
5280 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5281 flag. It can be used to send message requests.
5283 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Implemented the RESTART command in the client.
5287 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5288 notice type messages. Added notice printing to the user
5291 * The channel keys are not re-generated if the channel's mode
5292 is PRIVKEY, ie private key on the channel exists. Affected
5293 files silcd/server.c and silcd/command.c.
5295 * Fixed a little bug in channel message delivery when channel
5296 private keys are set in the server. Affected file is
5297 silcd/packet_send.c.
5299 * Changed the setting on channel->on_channel = TRUE from the
5300 silc_client_save_channel_key to the JOIN command reply. The
5301 key payload is not received if the private channel key is set.
5302 Affected file lib/silcclient/command_reply.c and the
5303 lib/silcclient/client_channel.c.
5305 * When the CMODE_CHANGE notify is sent and the channel private
5306 key mode is removed the channel key must be re-generated in
5307 other cells as well. Added this support for the router in the
5308 silcd/packet_receive.c.
5310 * Added new local command NOTICE to send notice message on
5311 channel. Affected file silc/local_command.[ch].
5313 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Added new local command ME to the client. It is used to send
5316 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5317 some action. Affected file silc/local_command.[ch].
5319 * Changed channel_message and private_message client operations
5320 to deliver the message flags to the application. Added also
5321 the `flags' arguments to the silc_client_send_channel_message
5322 and silc_client_send_private_message functions. Affected file
5325 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Redefined the Private Message Payload to support private message
5328 keys and to support the new private message flags. Updated
5329 the protocol specs. Flags makes it possible to have for example
5330 CTCP style messages.
5332 * Added new type SilcPrivateMessagePayload and defined an API
5333 for it in the lib/silcclient/silcprivate.[ch].
5335 * Tested private message private keys successfully. Tested the
5336 private message key set, unset and list commands with the new
5339 * Redefined the Channel Message Payload to include the channel
5340 message flags (equal with private message flags) to support
5341 for example CTCP style messages.
5343 * Defined some of the message (for channel and private message)
5344 flags. Updated the protocol specs and added the flags to the
5345 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5347 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Added SilcKeyAgreementStatus type to the key agreement routines
5350 to indicate the current status and error if one occured.
5351 The status types are defined in the lib/silcclient/silcapi.h.
5353 * Added new local command KEY that is used to set and unset private
5354 keys for channels, set and unset private keys for private messages
5355 with remote clients and to send key agreement requests and
5356 negotiate the key agreement protocol with remote client. The
5357 key agreement is supported only to negotiate private message keys,
5358 it currently cannot be used to negotiate private keys for channels,
5359 as it is not convenient for that purpose.
5361 * Fixed a minor pending callback setting bug in the function
5362 silc_client_get_client_by_id_resolve, now the function works.
5363 Affected file lib/silcclient/idlist.c.
5365 * Added function silc_net_get_local_port to get local bound
5366 port by socket. Added to lib/silcutil/silcnet.[ch].
5368 * Added `sockets' and `sockets_count' fields to the SilcClient
5369 object. They hold the sockets of the listenning sockets in
5370 the client. Listenning sockets may be for example the key
5371 agreement server. Affected file lib/silcclient/client.[ch].
5372 Added functions the silc_client_add_socket and the
5373 silc_client_del_socket. They are exported to the application
5376 * Added ~./silc/clientkeys to support other client's public keys.
5378 * Renamed verify_server_key client operation to verify_public_key
5379 and added one argument to indicate the type of the connection
5380 (server, client etc.).
5382 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Added silc_server_connection_auth_request to handle the
5385 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5386 silcd/packet_receive.[ch].
5388 * Added silc_server_send_connection_auth_request into the
5389 silcd/packet_send.c to send the connection auth request packet.
5391 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5394 * Fixed the public key authentication in responder side in the
5395 server. The `auth_data' pointer includes the SilcPublicKey
5396 not the path to the public key. Affected file silcd/protocol.c.
5398 * Implemented the public key authentication in the initiator side
5399 in the server. Affected file silcd/protocol.c.
5401 * Removed the [RedirectClient] config section from the server
5402 configuration. Is not needed and I don't want to implement it.
5404 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Cleaned up the CMODE command in the server. It now works
5407 correctly and supports all the modes defined in the protocol.
5408 Affected file is silcd/command.c.
5410 * Added `hmac_name' field to the SilcChannelEntry in the server
5411 to hold the default HMAC of the channel. It can be set when
5412 creating the channel (with JOIN command). Affected files
5415 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5416 type to indicate the change of the current cipher and hmac
5417 on the channel. Client can safely ignore the <cipher> argument
5418 (if it chooses to do so) since the CHANNEL_KEY packet will
5419 force the channel key change anyway. The <hmac> argument is
5420 important since the client is responsible of setting the new
5421 HMAC and the hmac key into use.
5423 * Fixed the CMODE command in the client library as well.
5425 * Tested CMODE command in router environment successfully.
5427 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Show the version of the remote client (or server) when connecting
5430 to the server. It is logged to the log file. Affected file
5431 is silcd/protocol.c.
5433 * Fixed the KILLED notify handling in the client library. The
5434 client must be removed from all channels when receiving the
5437 Also, do not remove the client entry when giving the KILL
5438 command but when the KILLED notify is received.
5440 * Removed silc_idlist_find_client_by_nickname from the server.
5441 Not needed anymore. Affected files silcd/idlist.[ch].
5443 * Implemented the CHANNEL_CHANGE notify type handling to the
5444 server. Affected file silcd/server.c.
5448 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Added silc_server_send_notify_invite to send the INVITE
5451 notify between routers.
5453 * Implemented the INVITE command correctly to the server.
5455 * Implemented the INVITE notify type handling in the server.
5457 * Implemented the INVITE command to the client library and on the
5460 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Added function silc_server_get_client_resolve to find the
5463 client entry by ID from all ID lists and then resolve it
5464 (using WHOIS) if it cannot be found. Affected file is
5467 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Implemented the BAN command to the client library.
5471 * The JOIN command in the server now checks the invite list
5474 * Changed the silc_command_reply_payload_encode_va and the
5475 silc_command_payload_encode_va to support that if argument is
5476 NULL it ignores and checks the next argument. Affected file
5477 lib/silccore/silccommand.c.
5479 * Added silc_server_send_notify_ban to send the BAN notify
5480 type between routers.
5482 * Chaned the silc_notify_payload_encode to support that if
5483 argument is NULL it ignores and checks the next argument.
5484 Affected file lib/silccore/silcnotify.c.
5486 * Tested ban lists in router environment successfully.
5488 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Implemented BAN command to the server, in silcd/command.[ch].
5492 * Removed the BAN and INVITE_LIST modes from the CMODE command
5495 * Added function silc_string_match to regex match two strings.
5496 Affected files lib/silcutil/silcutil.[ch].
5498 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Redefined parts of the SilcChannelEntry in the server to support
5501 the new ban and invite lists.
5503 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Redefined the INVITE command. The same command can be used to
5506 invite individuals to the channel but also to manage the invite
5507 list of the channel (to add to and remove from the invite list).
5508 Updated the protocol specs.
5510 * Added new command SILC_COMMAND_BAN that can be used to manage
5511 the ban list of the channel. Updated the protocol specs.
5513 * Removed the channel modes: the SILC_CMODE_BAN and the
5514 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5515 in the CMODE command. The equivalent features are now available
5516 using INVITE and BAN commands. Updated the protocol specs.
5518 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5519 in the network about change in the current ban list. The notify
5520 type is not used by the client.
5522 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5523 support the invite lists.
5525 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Added new function silc_string_regexify that converts string
5528 including wildcard characters into regex string that can
5529 be used by the GNU regex library. Added into the file
5530 lib/silcutil/silcutil.[ch].
5532 Added silc_string_regex_combine to combine to regex strings
5533 into one so that they can be used as one regex string by
5534 the GNU regex library. Added into the file
5535 lib/silcutil/silcutil.[ch].
5537 Added silc_string_regex_match to match two strings. It returns
5538 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5540 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Imported GNU regex to the soruce tree into lib/contrib.
5543 Fixed some compiler warning from the regex.c.
5545 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Fixed MOTD command in the server to work in router environment.
5549 * Fixed the MOTD command in the client library to support
5550 the server argument in the command.
5552 * Added `nickname_len' argument to the silc_idlist_add_client
5553 in the server, as the `nickname' argument may be binary data
5556 * Added silc_idlist_get_channels to return all channels from
5559 * Implemented LIST command to the server. Affected file is
5562 * Implemented the LIST command to the client library and on the
5565 * Added [<user count>] argument to the LIST command reply.
5566 With private channels the user count is not shown.
5568 * Updated TODO and README.
5570 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * The client entry's data.registered must be TRUE even with
5573 global client entry on global client list. The data.registered
5574 is used to check whether the client is anymore in the network,
5575 for example with WHOWAS command so it must be valid.
5577 * Fixed the WHOWAS command in the server. It now actually works
5578 in router environment. Added function into silcd/command_reply.c
5579 silc_server_command_reply_whowas_save.
5581 * Added silc_idlist_purge function to the silcd/idlist.c
5582 to periodically purge the ID Cache.
5584 * Fixed INFO command in the server. It works now in router
5585 environment. Added <server name> argument to the INFO command
5586 reply. Updated the protocol specs.
5588 * Fixed minor bug in silc_idcache_purge to not purge if the
5589 expire value is zero.
5591 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5592 they were buggy because of the WHOWAS information.
5594 * Fixed local command MSG to handle the async resolving of
5595 the remote client properly. It used to fail the first MSG.
5596 Affected file silc/local_command.c.
5598 * Added `data_len' field to SilcIDCache context.
5600 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Update TODO. Todo in commands in the server.
5604 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5607 used by routers as broadcast packet to inform other routers
5608 about the changed user mode.
5610 Implemented the notify handling in the server. Affected file is
5611 silcd/packet_receive.c. Added the function
5612 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5614 * Added new generic Channel Payload and deprecated the New Channel
5615 Payload. The New Channel Payload is now the generic Channel
5618 * Added new argument `mode' to the silc_server_send_new_channel
5619 as it is required in the Channel Payload now.
5621 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5622 and created a new and real SilChannelPayload to represent the
5623 new generic Channel Payload. Implemented the encode/decode
5624 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5626 * Added silc_server_get_client_channel_list to return the list
5627 of channels the client has joined for WHOIS command reply.
5628 Affected file silcd/server.[ch].
5630 * Implemented the channel list sending in the WHOIS command reply
5631 in server and in the client.
5633 Implemented the channel list displaying on the user interface
5634 as well. Affected file silc/client_ops.c.
5636 * Added silc_channel_payload_parse_list to parse list of Channel
5637 Payloads. It returns SilcDList list of SilcChannelPayloads.
5638 Client for example can use this function to parse the list of
5639 channels it receives in the WHOIS command reply. The caller
5640 must free the list by calling silc_channel_payload_list_free.
5641 Affected files lib/silccore/silcchannel.[ch].
5643 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Added one new argument <user mode> to the WHOIS command reply
5646 to return the mode of the user in SILC. Updated the protocol
5649 Implemented it to the server and client.
5651 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Fixed the mode printing on the user interface on joining.
5654 Affected file silc/client_ops.c.
5656 * Implemented the UMODE command and user modes in general to the
5657 client library and to the user interface.
5659 * Implemented the UMODE command to the server.
5661 * The server now sends UNKNOWN_COMMAND error status if client sends
5662 unknown command. Affected file silcd/command.c.
5664 * All server commands now handle the command identifier the right
5665 way when sending the command reply to the client. The client can
5666 use to identify the command replies with the identifier.
5668 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Added silc_server_get_client_route to resolve the route to
5671 the client indicated by the client ID. Affected file is
5674 * Added silc_server_relay_packet as general function to relay
5675 packet to arbitrary destination. This deprecates functions
5676 like _send_private_message_key, _relay_notify etc. Affected
5677 file is silcd/packet_send.[ch].
5679 Removed silc_server_send_key_agreement,
5680 silc_server_send_private_message_key and
5681 silc_server_packet_relay_notify functions from the file
5682 silcd/packet_send.[ch].
5686 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5687 server. Affected file silcd/packet_receive.[ch].
5689 * Implemented the KILL command to the client. Implemented the
5690 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5691 Affected files lib/silcclient/command[_reply].c and
5692 lib/silcclient/client_notify.c. Implemented the KILL notify
5693 printing in the user inteface.
5695 * Fixed a lot silc_parse_nick memory leaks from the client
5696 library in the file lib/silcclient/command.c.
5698 * Changed the silc_server_send_notify_on_channels's `sender'
5699 argument from SilcSocketConnection to SilcClientEntry to
5700 check the sender as entry and not as connection object and not
5701 to send to the client provided as argument. The affected file
5702 is silcd/packet_send.[ch].
5704 * The notify packets that are destined directly to the client used
5705 to not to be processed by the server. Now changed that and the
5706 server processes all notify packets. After relaying the packet
5707 to the client the notify packet is processed in the server.
5709 * The silc_server_free_client_data now checks whether there is
5710 pending outgoing traffic for the client and purges the data to
5711 the network before removing the client entry.
5713 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5716 an client is killed from the SILC Network. Updated the protocol
5719 Added new function silc_server_send_notify_killed to the
5720 silcd/packet_send.[ch].
5722 * Added function silc_server_packet_relay_notify to relay notify
5723 packets that are destined directly to a client. In this case
5724 the server does not process the notify packets but merely relays
5725 it to the client. Affected file silcd/packet_send.[ch].
5727 Added also silc_server_packet_process_relay_notify to check
5728 whereto relay the notify. Affected file is
5729 silcd/packet_receive.[ch].
5731 * Implemented the KILL command to the server.
5735 * Added the backup schema desgined last fall to the protocol
5736 specs for everyone to see. The specification is in the
5737 *-spec-xx.txt draft and the packet type definitions for the
5738 backup routers is in *-pp-xx.txt draft. Thusly, added also
5739 new packet type SILC_PACKET_CELL_ROUTERS.
5741 * A big security problem in the implementation discovered. The
5742 signoff of an client did not cause new channel key generation
5743 which it of course should've done. The channel keys must be
5744 always re-generated when client leaves (or signoffs) the channel.
5745 The silc_server_remove_from_channels funtion now handles
5746 the channel key re-generation.
5748 * Added `sender' argument to the silc_server_send_notify_on_channels
5749 to not to send the client provided as argument. Affected file
5750 silcd/packet_send.[ch].
5752 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Implemented OPER and SILCOPER commands into the server and
5757 * Added silc_auth_verify and silc_auth_verify_data to verify
5758 the authentication directly from the authentication payload.
5759 It supports verifying both passphrase and public key based
5760 authentication. Affected file lib/silccore/silcauth.[ch].
5762 * Added `hash' field to the SilcIDListData structure. It is the
5763 hash negotiated in the SKE protocol. Affected file is
5766 * Slight redesigning of the SilcAuthPayload handling routines.
5767 Do not send SilcPKCS but SilcPublicKey as argument.
5769 * Implemented the public key authentication support to the
5770 serverconfig. The public key is loaded from the provided path
5771 and saved as authentication data to void * pointer. Thus,
5772 changed the unsigned char *auth_data to void *auth_data;
5774 * Fixed SHUTDOWN command to send the reply before the server
5775 is shutdown. :) Affected file silcd/command.c.
5777 * Fixed fatal bug in CONNECT command. The hostname was invalid
5778 memory and server crashed. Affected file silcd/command.c.
5780 * Fixed fatal bug in CLOSE command. The server_entry became
5781 invalid but was referenced later in the command. Affected file
5784 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Fixed fatal bug in failure packet handling. Server ignored
5787 the failure and thus crashed when it came.
5791 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5794 that the command may be executed only once in (about) 2 seconds.
5795 The old SILC_CF_LAG flag is same but allows command bursts up
5796 to five before limiting.
5798 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5799 server code. Various commands now includes the CF_LAG_STRICT
5800 flag to disallow any kind of miss-use of the command.
5802 * Fixed the silc_buffer_unformat to not to allocate any data
5803 if the length of the data is zero. It used to allocate the
5804 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5806 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Changed the format of AdminConnection configuration section
5809 in the server. Added username of the admin to the format.
5810 Affected files silcd/serverconfig.[ch].
5812 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5813 to return admin configuration data by host, username and/or
5816 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * Implemented WHOWAS command to the server. Added the functions:
5820 silc_server_command_whowas_parse,
5821 silc_server_command_whowas_send_reply,
5822 silc_server_command_whowas_from_client and
5823 silc_server_command_whowas_from_server
5825 * Added <Client ID> argument to the WHOWAS command reply. Updated
5826 the protocol specs accordingly.
5828 * Implemented WHOWAS command and command_reply to the client
5831 Implemented the WHOWAS printing on the user interface.
5833 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Added new argument to the WHOWAS command reply, the real name.
5836 It is an optional argument. Updated the protocol specs.
5838 * Added SilcIDCacheDestructor callback that is registered when
5839 the SilcIDCache is allocated. The callback is called when
5840 an cache entry in the ID Cache expires, or is purged from the
5841 cache. Added into lib/silccore/idcache.[ch].
5843 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5844 to destruct the client entries when the cache entry expires.
5845 Other ID Cache's in server and in the client library ignores
5848 * If the ID Cache entry's `expire' field is zero then the entry
5849 never expires. Added boolean `expire' argument to the
5850 silc_idcache_add function in the lib/silccore/idcache.[ch].
5851 If it is TRUE the default expiry value is used.
5853 * Added silc_server_free_client_data_timeout that is registered
5854 when client disconnects. By default for 5 minutes we preserve
5855 the client entry for history - for WHOWAS command.
5857 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Added support to the server to enforce that commands are not
5860 executed more than once in 2 seconds. If server receives
5861 commands from client more frequently, timeout is registered
5862 to process the commands. Affected file silcd/command.c.
5863 Added new function silc_server_command_process_timeout.
5865 * Changed NICK_NOTIFY handling in client library to check that
5866 if the client's nickname was changed, so there is no need to
5867 resolve anything from the server.
5869 * Removed error printing from the WHOIS and IDENTIFY commands.
5870 If error occurs then it is ignored silently in the client library.
5871 The application, however, may map the received error to
5872 human readable error string. The application currently maps
5873 the NO_SUCH_NICKNAME error to string.
5875 * Made the command status message public to the application. Moved
5876 them from lib/silcclient/command_reply.c to
5877 lib/silcclient/command_reply.h. The application can map the
5878 received command status to the string with the
5879 silc_client_command_status_message function.
5881 * Added check to the server to check that client's ID is same
5882 as the Source ID in the packet the client sent. They must
5885 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Added dist-bzip hook to the Makefile.am to make bzip2
5888 compressed distributions.
5890 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Server now enforces the maximum length for the nickname and
5893 the channel as protocol specification dictates. 128 bytes for
5894 nickname and 256 bytes for channel name.
5896 * Moved the WHOIS printing to the application. The client libary
5897 does not print out the WHOIS information anymore, the application
5898 must do it. Renamed silc_client_command_reply_whois_print to
5899 the silc_client_command_reply_whois_save.
5901 The client's idle time is also sent to the application now, and
5902 the idle is shown on screen.
5904 * Added silc_client_command_reply_identify_save to save the
5905 received IDENTIFY entries.
5907 * Do not check for channel private keys in message sending and
5908 reception if the channel does not have the PRIVKEY mode set.
5909 Affected file lib/silclient/client_channel.c.
5911 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5914 just surfaced after chaning the JOIN procedure.
5916 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added silc_client_get_clients_by_list to get client entries
5919 from Client ID list, that is returned for example by JOIN
5920 and USERS command replies. The application should use this
5921 function for example when JOIN command reply is received to
5922 resolve the clients already on the channel (library does not
5923 do that anymore as USERS command reply is not used in the JOIN
5924 procedure anymore). Affected files lib/silcclient/silcapi.h and
5925 lib/silcclient/idlist.c.
5927 * JOIN command reply and USERS command reply returns now SilcBuffer
5928 pointers instead of unsigned char pointers when returning
5929 the client list and mode list.
5931 * Added <Client ID> argument to the JOIN command reply, mainly
5932 for the server to identify for which client the command was
5933 originally sent. Updated protocol specs accordingly.
5935 * Added SilcDlist private_key pointer to the SilcChannelEntry
5936 in the client to support the channel private keys. Affected
5937 file is lib/silcclient/idlist.h.
5939 * Added SilcChannelPrivateKey argument to the function
5940 silc_client_send_channel_message so that application can choose
5941 to use specific private ke if it wants to. If it is not provided,
5942 the normal channel key is used, unless private keys are set.
5943 In this case the first (key that was added first) is used
5944 as the encryption key.
5946 * Implemented the support for channel private key handling.
5947 Implemented the following functions:
5949 silc_client_add_channel_private_key,
5950 silc_client_del_channel_private_keys,
5951 silc_client_del_channel_private_key,
5952 silc_client_list_channel_private_keys and
5953 silc_client_free_channel_private_keys
5955 Affected file lib/silcclient/client_channel.c.
5957 * Added the support for the private keys in the channel message
5958 sending and encryption and in the message reception and
5959 decryption. Affected funtions are
5960 silc_client_send_channel_message and silc_client_channel_message.
5962 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Added SKE's key verify callback to the client library's
5965 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5967 * Removed the statement that server (or router) must send USERS
5968 command reply when joining to the channel so that the client
5969 knows who are on the channel. Instead, the client list and
5970 client's mode list is now sent in the JOIN command reply to the
5971 client who joined channel. This is better solution.
5973 * Added function silc_server_get_users_on_channel and function
5974 silc_server_save_users_on_channel to the silcd/server.[ch].
5976 * Removed function silc_server_command_send_users from the
5979 * Do not show topic on the client library anymore. The topic is
5980 sent in the command reply notify to the application and the
5981 application must show the topic now.
5983 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Added client searching by nickname hash into the IDENTIFY and
5986 WHOIS commands in the server as they were clearly missing from
5987 them. Affected file is silcd/command.c.
5989 * Fixed a bug in private message receiving in the client library.
5990 The remote ID was freed and it wasn't supposed, now it is
5993 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Minor fix to the channel payload; allocate the data area, as it
5996 needs to be of specific length.
5998 * If the key agreement port is zero then the operating
5999 system will define the bound port. Affected files are
6000 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6002 * Added new function silc_channel_payload_decrypt into the file
6003 lib/silccore/silcchannel.[ch].
6005 * Moved the channel message etc, check from silc_packet_decrypt
6006 to applications. The library calls now a generic
6007 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6008 when the packet is either normal or special. This was done to
6009 allow more wide range of checking that was not allowed when
6010 the code was in library. Now applications can do virtually any
6011 checks to the packet and return to the library the decision how
6012 the packet should be processed. Affected files are
6013 lib/silccore/silcpacket.[ch].
6015 Added silc_server_packet_decrypt_check to the server and
6016 silc_client_packet_decrypt_check to the client library.
6018 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6019 to send with specified source and destination information.
6021 * Channel message delivery between routers was broken after the
6022 channel key distribution was fixed earlier. The channel key
6023 was used be to distributed to other routers as well which is not
6024 allowed by the protocol. Now this is fixed and channel keys
6025 really are cell specific and the channel message delivery between
6026 routers comply with the protocol specification.
6028 * Fixed various commands in server to check also the global list
6029 for the channel entry and not just the local list. The affected
6030 file silcd/command.c.
6032 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Added assert()s to buffer formatting and unformatting routines
6035 to assert (if --enable-debug) when error occurs. Affected
6036 file: lib/silcutil/silcbuffmt.c.
6038 * Changed to auto-reconnect to check whether the remote host is
6039 router and register the re-connect timeout if it is. It used
6040 to check that whether we are normal server, but router must do
6041 auto-reconnect with another router as well. Affected file
6044 * Removed the [<key len>] option from CMODE command as the cipher
6045 name decides the key length, nowadays. See the defined ciphers
6046 from the protocol specification.
6048 * Added [<hmac>] option to the CMODE command to define the HMAC
6049 for the channel. Added SILC_CMODE_HMAC channel mode.
6051 * Added [<hmac>] option for the JOIN command so that user can
6052 select which HMAC is used to compute the MACs of the channel
6055 * Added Hmac field to the Channel Message Payload. The integrity
6056 of plaintext channel messages are now protected by computing
6057 MAC of the message and attaching the MAC to the payload. The
6058 MAC is encrypted. Now, it is clear that this causes some
6059 overhead to the size of the packet but rationale for this is that
6060 now the receiver can verify whether the channel message decrypted
6061 correctly and also when private keys are set for the channel the
6062 receiver can decrypt the packet with several keys and check from
6063 the MAC which key decrypted the message correctly.
6065 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6066 lib/silccrypt/silccipher.[ch].
6068 * Added silc_hash_len to return the digest length into the
6069 lib/silcrypt/silchash.[ch].
6071 * Rewrote parts of Silc Channel Payload interface in the
6072 lib/silccore/silcchannel.[ch]. The encode function now also
6073 encrypts the packet and parse function decrypts it.
6075 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Fixed a minor formatting bug in the SKE's key material processing.
6078 It actually might have processed the keys wrong way resulting
6081 * Redefined the mandatory HMAC algorithms and added new algorithms.
6082 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6083 and hmac-md5 truncated to 96 bits. The mandatory is now
6084 hmac-sha1-96. Rest are optional (including the one that used
6085 to be mandatory). Rationale for this is that the truncated HMAC
6086 length is sufficient from security point of view and can actually
6087 make the attack against the HMAC harder. Also, the truncated
6088 HMAC causes less overhead to the packets. See the RFC2104 for
6091 * Added new [hmac] configuration section. The SKE used to use
6092 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6093 is of course wrong. The official names that must be proposed in
6094 the SKE are the ones defined in the protocol specification
6095 (hmac-sha1-96 for example). The user can configure any hmac
6096 using any hash function configured in the [hash] section. At
6097 least, the mandatory must be configured.
6099 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6101 * Added HMAC list to the SKE proposal list. It has now both
6102 hash algorithm list and HMAC list. This makes the protocol
6103 incompatible with previous versions. The SKE now seems to work
6104 the way it is supposed to work, for the first time actually.
6106 * Defined plain Hash algorithms to the protocol specification.
6109 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Implemented support for key agreement packets into the server.
6112 Added functions silc_server_key_agreement and
6113 silc_server_send_key_agreement. Other than these functions,
6114 server has nothing to do with this packet.
6116 * Added support for private message key packets into the server.
6117 Added functions silc_server_private_message_key and
6118 silc_server_send_private_message_key.
6122 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6123 called in the protocol's final callback instead in the END
6124 protocol state. This makes a little more sense and in the same
6125 time in client we can use the same protocol routines for normal
6126 key exchange and to key agreement packet handling as well.
6128 * Added to both client's and server's KE protocol context the
6129 SilcSKEKeyMaterial pointer to save the key material. We will
6130 bring the key material to the protocol's final callback by doing
6131 this. The final callback must free the key material.
6133 * Added SKE's packet_send callback into client's KE protocol
6134 context so that the caller can choose what packet sending function
6135 is used. This way we can use different packet sending when
6136 doing normal SKE when doing key agreement packet handling (in
6137 the key agreement packet handling we do not want to encrypt
6140 * Implemented the responder side of the key agreement routines
6141 in the client. The client can now bind to specified port and
6142 accept incoming key negotiation. The key material is passed
6143 to the application after the protocol is over.
6145 * Implemented the processing of incoming Key Agreement packet
6146 in the client. Added function silc_client_key_agreement to
6149 * Implemented the intiator side of the key agreement routines
6150 in the client. The client can now initiate key agreement with
6151 another remote client. The key material is passed to the
6152 application after the protocol is over.
6154 * Created client_keyagr.c to include all the key agreement
6157 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6158 SILC_TASK_CALLBACK except that it is not static.
6160 * Created client_notify.c and moved the Notify packet handling
6161 from the client.[ch] into that file.
6163 * Created client_prvmsg.c and moved all private message and
6164 private message key routines from the client.[ch] into that file.
6166 * Create client_channel.c and moved all channel message and
6167 channel private key routines from the client.[ch] into that file.
6169 * Changed silc_client_get_client_by_id_resolve to resolve with
6170 WHOIS command instead of IDENTIFY command, in the file
6171 lib/silclient/idlist.c.
6173 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Implemented the SKE's responder side to the Client library.
6177 * When FAILURE is received to the protocol do not trust it
6178 blindly. Register a timeout to wait whether the remote closes
6179 the connection as it should do it, only after that process the
6180 actual failure. This was changed to both client and server.
6182 * Added client_internal.h to include some of the structures
6183 there instead of client.h in lib/silcclient/.
6185 * Added function silc_task_unregister_by_callback to unregister
6186 timeouts by the callback function.
6188 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Some "Incomplete WHOIS info" errors has been appearing on the
6191 log files. Took away the entry->userinfo check from WHOIS
6192 reply sending. The entry->userinfo is now " " if client did not
6193 provide one. I thought this was fixed earlier but something
6194 is wrong still. Let's see if the error still appears.
6196 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Fixed a minor bug in the login when the channel key is
6199 re-generated in the server. It used to generate the key in
6200 wrong order and thus caused problems in the channel traffic.
6202 * Fixed a minor bug in channel key distsribution after
6203 KICK command. The key was not sent to the router even though
6206 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Added silc_ske_process_key_material_data as generic routine
6209 to process any key material as the SILC protocol dictates. The
6210 function is used by the actual SKE library but can be used by
6211 applications as well. This relates to the private message keys
6212 and the channel private keys since they must be processed the
6213 same way the normal SILC session keys. The protocol dictates
6214 this. Affected files: lib/silcske/silcske.[ch].
6216 Added also silc_ske_free_key_material to free the
6217 SilcSKEKeyMaterial structure.
6219 * Defined silc_cipher_set_key function to set the key for
6220 cipher without using the object's method function. The affected
6221 files: lib/silccrypt/silccipher.[ch].
6223 * Implemented silc silc_client_add_private_message_key,
6224 silc_client_add_private_message_key_ske,
6225 silc_client_del_private_message_key,
6226 silc_client_list_private_message_keys and
6227 silc_client_free_private_message_keys functions in the
6230 Added functions silc_client_send_private_message_key to send
6231 the Private Message Key payload and silc_client_private_message_key
6232 to handle incoming Private Message Key payload.
6234 * Added Cipher field to the Private Message Key payload to set
6235 the cipher to be used. If ignored, the default cipher defined
6236 in the SILC protocol (aes-256-cbc) is used.
6238 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Removed lib/silcclient/ops.h file.
6242 Redefined parts of the SILC Client Library API. Created new
6243 file silcapi.h that deprecates the ops.h file and defines the
6244 published Client Library API. Defined also private message key
6245 API and channel private key API into the file.
6247 This is the file that the application must include from the
6248 SILC Client Library. Other files need not be included by
6249 the application anymore.
6251 * Added new key_agreement client operation callback and also
6252 defined the Key Agreement library API for the application.
6254 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6257 is used by clients to request key negotiation between another
6258 client in the SILC network. If the negotiation is started it
6259 is performed using the SKE protocol. The result of the
6260 negotiation, the secret key material, can be used for example
6261 as private message key.
6263 Implemented the Key Agreement payload into the files
6264 lib/silccore/silauth.[ch].
6266 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Redefined ciphers for the SILC protocol. Added some new ciphers
6269 and defined the key lengths for the algorithms. Changed the
6270 code accordingly. The default key length is now 256 bits.
6272 * Fixed SKE key distribution function silc_ske_process_key_material
6273 when the key length is more than 128 bits. The default key
6274 length in SILC is now 256 bits.
6276 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6277 to indicate unsupported algorithm.
6279 * Renamed rijndael.c to aes.c and all functions as well.
6281 * Fixed a long standing channel key setting bug in client library.
6282 Weird that it has never surfaced before.
6284 * Fixed bug in channel deletion. If the entire channel is removed
6285 then it must also delete the references of the channel entry
6286 from the client's channel list as the client's channel entry and
6287 the channel's client entry share same memory.
6289 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Implemented CONNECT and SHUTDOWN commands in the client.
6293 * Implemented CLOSE command to the client.
6295 * Added the function silc_idlist_find_server_by_name into the
6296 files silcd/idlist.[ch].
6298 Added the function silc_idlist_find_server_by_conn into the
6299 files silcd/idlist.[ch].
6301 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * DIE command was renamed to SHUTDOWN. Updated the both code
6306 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6307 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6309 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6312 * Added function silc_server_create_connection function to create
6313 connection to remote router. My server implementation actually
6314 does not allow router to connect to normal server (it expects
6315 that normal server always initiates the connection to the router)
6316 so the CONNECT command is only good for connecting to another
6319 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6322 or some other client was kicked from the channel.
6324 Implemented the handling of the notify type to both client
6327 Implemented silc_server_send_notify_kicked to send the KICKED
6328 notify. It is used to send it to the server's primary router.
6330 * Implemented the KICK command into server and client.
6332 * Added `query' argument to the silc_idlist_get_client function
6333 to indicate whether to query the client from server or not if
6336 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6337 to indicate that the client is not channel founder.
6341 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Removed the rng context from SilcPacketContext structure and
6344 changed that the packet routine uses the Global RNG API.
6346 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6348 * Added support for quit message that client can "leave" on the
6349 channel when it quits the SILC. It is ditributed inside the
6350 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6352 Added silc_server_free_client_data that will take the
6353 signoff message as argument.
6355 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6357 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Updated parts of the protocol specification to keep it up
6362 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6365 payloads in one packet.
6367 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6368 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6369 use now the new List flag.
6371 * Also deprecated the following packet types: REPLACE_ID,
6372 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6374 * Added list support for Notify packet in server.
6376 * Added silc_server_send_notify_channel_change to send the
6377 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6378 the silc_server_send_replace_id.
6380 * Added silc_server_send_notify_nick_change to send the
6381 NICK_CHANGE notify type. Deprecates the function
6382 silc_server_send_replace_id.
6384 * Added silc_server_send_notify_join to send the JOIN notify type.
6385 Deprecates the function silc_server_send_new_channel_user.
6387 * Added silc_server_send_notify_leave to send LEAVE notify type.
6388 Deprecates the function silc_server_send_remove_channel_user.
6390 * Added silc_server_send_notify_cmode and
6391 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6392 types. Deprecates the silc_server_send_set_mode function.
6394 * Added SERVER_SIGNOFF notify type to indicate that server has
6395 quit. This means that all clients on the channel from that
6396 server will drop. This can be also used when netsplit happens.
6398 Deprecated REMOVE_ID packet type since it is not needed anymore
6401 Added silc_server_send_notify_server_signoff to send the
6402 SERVER_SIGNOFF notify type. Deprecates the function
6403 silc_server_send_remove_id.
6405 Added also silc_server_send_notify_signoff to send the
6406 SIGNOFF notify type.
6408 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6409 SILC protocol from this day on. Changed the protocol
6410 specification as well.
6412 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6413 notify type. It is used between routers to notify about
6414 topic changes on a channel.
6416 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6419 * Partly updated the protocol specification to comply with the
6420 changes now made. It is still though a bit outdated.
6422 * The JOIN notify type now takes one extra argument <Channel ID>.
6423 The packet used to be destined to the channel but now the
6424 JOIN type may be sent as list thus it is impossible to
6425 destine it to any specific channel. By adding this argument
6426 it is again possible.
6428 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Added CREDITS file. The CHANGES and CREDITS file will appear
6431 in the distribution as well.
6433 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6436 types in the server's silcd/packet_receive.c.
6438 * Implemented CMODE and CUMODE to work in router environment.
6440 * Fixed minor encoding and decoding buglet from the
6441 lib/silccore/silcmode.c.
6443 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6446 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6448 * Changed all SilcConfigServer* and silc_config_server* to
6449 SilcServerConfig* and silc_server_config*, respectively.
6452 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Associated the ID (client or server ID) to the Authentication
6455 Payload to avoid any possibility of forging. Updated the
6456 protocol specification and the code accordingly.
6458 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * The RSA key length is now save to the RsaKey context in the
6461 key generation process in lib/silccrypt/rsa.c. The key length
6462 is now used to figure out the maximum size of the block allowed
6463 to be encrypted/signed.
6465 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6466 is equivalent to the silc_mp_mp2bin but does not allocate any
6469 * Changed silc_mp_mp2bin API to take length argument. If it is
6470 non-zero then the buffer is allocated that large. If zero, then
6471 the size is approximated using silc_mp_sizeinbase, which however
6474 * Created Global RNG API which is global RNG that application can
6475 initialize. After initializing, any routine anywhere in the
6476 code (including library) can use RNG without allocating a new
6477 RNG object. This was done to allow this sort of use of the
6478 RNG in code that has no chance to allocate RNG object. All
6479 applications currently allocate this and many routines in the
6480 library use this. Affected file lib/silccrypt/silcrng.[ch].
6482 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6483 it to use the Global RNG API.
6485 * Defined Authentication Payload into protocol specification that
6486 is used during SILC session to authenticate entities. It is
6487 used for example by client to authenticate itself to the server
6488 to obtain server operator privileges.
6490 Implemented this payload into the lib/silccore/silcauth.[ch].
6491 Implemented also routines for public key based authentication
6492 as the new protocol specification dictates.
6494 Moved definitions of different authentication methods from
6495 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6497 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6498 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6499 silc_pkcs_verify_with_hash functions into the file
6500 lib/silccrypt/silcpkcs.[ch].
6502 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * The client entry's userinfo pointer must be always valid.
6505 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6506 will fail since it requires the userinfo. Now, the userinfo
6507 is allocated as "" if actual userinfo does not exist. Actually,
6508 it must exist and it is totally Ok to drop client connections
6509 that does not announce the userinfo. However, we will make
6510 this workaround for now.
6512 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6513 to return the remote port by socket.
6515 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6518 SILC_SERVER_PENDING_EXEC and added an new macro
6519 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6520 data or when error occurs while processing the pending command.
6522 Added new argument `destructor' into silc_server_command_pending
6523 and to the SilcServerCommandPending object. This destructor is
6524 now called after calling the pending callback or if error occurs
6525 immediately. If error occurs the actual pending callback won't
6526 be called at all - only the destructor. The destructor may be
6527 NULL if destructor is not needed.
6529 All this applies for client library code as well. Similar
6530 changes were made there as well for the pending commands.
6532 In the client, the application must now allocate the
6533 SilcClientCommandContext with the silc_client_command_alloc
6536 * Added reference counter to the SilcServerCommandContext. Added
6537 function silc_server_command_alloc and silc_server_command_dup
6540 Same type of functions added to the client library for the same
6543 * Removed the cmd_ident from IDListData away since it is now
6544 global for all connections. It is the command identifier used
6545 in command sending and with pending commands. The affected file
6548 * Added reference counter to the SilcSocketConnection objecet to
6549 indicate the usage count of the object. The object won't be
6550 freed untill the reference counter hits zero. Currently only
6551 server uses this, and client ignores it. The client must be
6552 set to use this too later. The affected files are
6553 lib/silccore/silcsockconn.[ch]. Added also the function
6554 silc_socket_dup to increase the reference counter.
6556 This was mainly added because it is possible that the socket
6557 is removed underneath of pending command or other async
6558 operation. Now it won't be free'd and proper DISCONNECTING
6559 flags, etc. can be set to avoid sending data to connection that
6560 is not valid anymore.
6562 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6563 the connection. After that it sets SILC_SET_DISCONNECTED.
6564 It is, however, possible that the socket data is not still freed.
6565 The silc_server_packet_process now checks that data is not
6566 read or written to connection that is DISCONNECTED. The socket
6567 get's freed when the reference counter hits zero.
6569 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * Changed the client operation API: channel_message operation's
6572 `sender' is now the client entry of the sender, not the nickname
6573 and the `channel' is the channel entry, not the channel name.
6575 In the private_message operation the `sender' is now also the
6576 client entry of the sender not the nickname.
6578 Affected file is lib/silcclient/ops.h and all applications
6579 using the client operations.
6581 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Moved the calling of ops->connect() from connect_to_server_final
6584 into receive_new_id functin since that is the point when the
6585 client is actually allowed to send traffic to network. The
6586 affected file is lib/silcclient/client.c.
6588 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6591 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6592 (if needs broadcasting) instead of broadcasting the packets one
6593 by one which would make a burst in the network traffic.
6595 * Added `broadcast' argument to the functions in silcd/server.[ch]
6596 silc_server_create_new_channel[_with_id] to indicate whether
6597 to send New Channel packet to primary router.
6599 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Added new function into the silcd/server.[ch] files:
6602 silc_server_create_new_channel_with_id to create new channel with
6603 already existing Channel ID.
6605 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6606 lib/silccore/silcpacket.h. This packet is used t send list of
6607 Set Mode payloads inside one packet. Server uses this to set
6608 the modes for the channels and clients on those channels, that it
6609 announced to the router when it connected to it. The protocol
6610 specification has been updated accordingly.
6612 * The silc_server_new_channel did not handle the packet coming
6613 from normal server as it normally does not send that. However,
6614 when it announces its channels it does send it. Implemented
6615 the support for that.
6617 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6618 into the file lib/silccore/id.h.
6620 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Fixed memory leaks in the functions silc_idlist_del_client,
6623 silc_idlist_del_channel and silc_idlist_del_server in the file
6624 silcd/idlist.c. All of those leaked like a sieve.
6626 * Fixed some small memory leaks in the client's function
6627 silc_client_notify_by_server.
6629 * Added functions into silcd/server.c: silc_server_announce_clients,
6630 silc_server_announce_channels and silc_server_announce_server.
6631 These functions are used by normal and router server to announce
6632 to its primary router about clients, channels and servers (when
6633 router) that we own. This is done after we've connected to the
6636 These functions effectively implements the following packet types:
6637 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6638 and SILC_PACKET_NEW_ID_LIST.
6640 * Added new functions into the silcd/packet_receive.[ch]:
6641 silc_server_new_id_list, silc_server_new_channel_list and
6642 silc_server_new_channel_user_list to handle the incoming
6643 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6645 * Added support of changing Channel ID in the function
6646 silc_server_replace_id. If the server that announces a channel
6647 to the router already exists in the router (with same name but
6648 with different Channel ID), router is responsible to send
6649 Replace ID packet to the server and force the server to change
6650 the Channel ID to the one router has.
6652 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6653 client that the Channel ID has been changed by the router. The
6654 normal server sends this to the client. Client must start using
6655 the new Channel ID as the channel's ID.
6657 Implemented handling of this new type into lib/silcclient/client.c
6658 into the function silc_client_notify_by_server.
6660 * Added new function silc_idlist_replace_channel_id into the files
6661 silcd/idlist.[ch] to replace the Channel ID.
6663 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Call silc_server_command_identify_check always when processing
6666 the IDENTIFY command in silcd/command.c
6668 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6671 send keepalive packets. The packet can be sent by clients,
6672 servers and routers.
6674 Added function silc_socket_set_heartbeat into the file
6675 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6676 If not set, the heartbeat is not performed. The actual
6677 heartbeat is implemented in the low level socket connection
6678 library. However, application is responsible of actually
6681 Added silc_server_send_heartbeat to send the actual heartbeat
6682 packet into silcd/packet_send.[ch]. Server now performs
6683 keepalive with all connections.
6685 * Added silc_task_get_first function into lib/silcutil/silctask.c
6686 to return the timeout task with shortest timeout. There was a bug
6687 in task unregistration that caused problems. TODO has been
6688 updated to include that task system must be rewritten.
6690 * The client library will now resolve the client information when
6691 receiving JOIN notify from server for client that we know but
6692 have incomplete information.
6694 * Rewrote parts of silc_server_remove_from_channels and
6695 silc_server_remove_from_one_channel as they did not remove the
6696 channel in some circumstances even though they should've.
6698 * Encryption problem encountered in server:
6700 The LEAVE command used to send the Channel Key packet to the
6701 router immediately after generating it. However, the code
6702 had earlier sent Remove Channel user packet but not immediately,
6703 ie. it was put to queue. The order of packets in the router
6704 was that Channel Key packet was first and Remove Channel User
6705 packet was second, even though they were encrypted in the
6706 reverse order. For this reason, MAC check failed. Now, this
6707 is fixed by not sending the Channel Key packet immediately but
6708 putting it to queue. However, this is more fundamental problem:
6709 packets that are in queue should actually not be encrypted
6710 because packets that are sent immediately gets encrypted
6711 actually with wrong IV (and thus MAC check fails). So, packets
6712 that are in queue should be encrypted when they are sent to
6713 the wire and not when they put to the queue.
6715 However, the problem is that the current system has not been
6716 designed to work that way. Instead, the packet is encrypted
6717 as soon as possible and left to the queue. The queue is then
6718 just purged into wire. There won't be any fixes for this
6719 any time soon. So, the current semantic for packet sending
6722 o If you send packet to remote host and do not force the send
6723 (the packet will be in queue) then all subsequent packets to the
6724 same remote host must also be put to the queue. Only after the
6725 queue has been purged is it safe again to force the packet
6728 o If you send all packets immediately then it safe to send
6729 any of subsequent packets through the queue, however, after
6730 the first packet is put to queue then any subsequent packets
6731 must also be put to the queue.
6733 Follow these rules and everything works fine.
6735 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Added new function silc_server_remove_clients_by_server to
6738 remove all client entries from ID list when the server connection
6739 is lost. In this case it is also important to invalidate all
6740 client entires as they hold the invalid server entry. This
6741 fixes fatal bug when server has lost connection and will reconnect
6744 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Made some sanity checks to silc_server_daemonise like to check
6747 whether the requested user and group actually exists.
6749 * Added sanity check to SKE's silc_ske_responder_finish to check
6750 that the public and private key actually is valid.
6752 * Invalidate the client's nickname when receiving Replace ID
6753 packet and the Client ID is being replaced. This means that the
6754 server will query the nickname if someone needs it (client)
6757 * Sort the ID Cache in client library when the ID Cache data
6758 has changed (needs sorting).
6760 * Do not allow for SILC client to create several connections to
6761 several servers. The client does not support windows right now
6762 and generating multiple connections causes weird behaviour.
6764 Irssi-silc client does support windows and can handle several
6765 connections without problems, see: www.irssi.org and SILC plugin.
6767 * Fixed some places where client was added to the IDList. The
6768 rule of thumb is following (in order to get everything right):
6769 If the client is directly connected local client then the
6770 `connection' argument must be set and `router' argument must be
6771 NULL to silc_idlist_add_client function. If the client is not
6772 directly connected client then the `router' argument must
6773 bet set and the `connection' argument must be NULL to the
6774 silc_idlist_add_client function.
6776 * The funtion silc_server_packet_send_local_channel actually did
6777 not check whether the client was locally connected or not. It
6778 does that now. Fixed a bug related to LEAVE command.
6780 * Fixed Remove Channel User payload parsing bug in server's
6781 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6783 * The server's silc_server_save_channel_key now checks also the
6784 global ID list for the channel as it might not be in the local
6785 list. Fixed a bug related to LEAVE command.
6787 * Is this the end of the [<unknown>] buglet that has been lurking
6788 around for a long time? A little for loop fix in server's
6789 silc_server_command_whois_parse that is used by both IDENTIFY
6790 and WHOIS command. At least, this was a clear bug and a cause
6791 of one type of [<unknown>] buglet.
6793 * WHOIS and IDENTIFY commands call the function
6794 silc_server_command_[whois/identify]_check function even if
6795 we are not router server.
6797 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6799 * Added --with-gmp configuration option. If set the GMP
6800 is always compiled in the SILC source tree. If not set then
6801 it is checked whether the system has the GMP3 installed. If
6802 it has then the GMP won't be compiled (the system's headers
6803 and library is used), if it doesn't have it then the GMP is
6804 compiled in the SILC source tree.
6806 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Changed RSA private exponent generation to what PKCS #1
6809 suggests. We try to find the smallest possible d by doing
6810 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6811 not security fix but optimization.
6813 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6815 * Added new config entry [Identity] to fork the server and run
6816 it as specific user and group. A patch from Bostik.
6818 * Imported Dotconf configuration library into lib/dotconf.
6819 This will be used to create the SILC configuration files later.
6820 It will appear in the distsribution after this commit.
6822 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * A big code auditing weekend happening. Auditing code for
6825 obvious mistakes, bugs and errors. Also, removing any code
6828 Removed files for being obsolete:
6830 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6831 inline in the file lib/silcutil/silcbuffer.h)
6833 o lib/silcutil/silcbufutil.c (the header has inline versions)
6835 Changed code to fix possible error conditions:
6837 o The buffer formatting routines now check that the destination
6838 buffer really has enough space to add the data. This applies for
6839 both buffer formatting and unformatting
6840 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6841 unformatting was changed to accomodate following rules:
6842 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6843 sent to the function while XXX_*STRING will not allocate or copy
6844 the data into the buffer. Instead it sets the pointer from the
6845 buffer into the pointer sent as argument (XXX_*STRING used to
6846 require that the pointer must be allocated already). This change
6847 makes this whole thing a bit more consistent and more optimized
6848 (note that the data returned in the unformatting with XXX_*STRING
6849 must not be freed now). The routines return now -1 on error.
6851 o Tried to find all code that use buffer_format and buffer_unformat
6852 and added return value checking to prevent formatting and
6853 especially unformatting errors and possible subsequent fatal
6856 o Changed ske->x and ske->KEY to mallocated pointers in
6857 lib/silcske/silcske.h. Fixed possible data and memory leak.
6859 o Added return value checking to all *_parse* functions. Fixed
6860 many memory leaks as well.
6862 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6863 so that buffer overflows would not happen. All code now also
6864 checks the return value as it can fail.
6866 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6868 * Added reconnection support to server if the normal server looses
6869 its connection to the router (for example if router is rebooted).
6870 The server performs normal reconnection strategy implemented
6871 to the server. Affected file silcd/server.c.
6873 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Added new packet type SILC_PACKET_SET_MODE that is used to
6876 distribute the information about changed modes (for clients,
6877 channels and clients channel modes) to all routers in the
6878 network. Updated the protocol specification accordingly.
6880 Added functions into silcd/packet_send.c and
6881 silcd/packet_receive.c: silc_server_send_set_mode,
6882 silc_server_set_mode.
6884 Added new files silcmode.[ch] into lib/silccore that implements
6885 the encoding and decoding of Set Mode Payload. Added new type
6886 SilcSetModePayload. Moved the definitions of different modes
6887 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6889 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Oops, a little mistake in server's connection authentication
6892 protocol. The protocol is not ended with FAILURE but with
6893 SUCCESS if the authentication is Ok. :) Affected file is
6896 * Implemented NICK_CHANGE notify handling in server in the file
6897 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6898 the local clients on the channel. After the changing nickname
6899 in router environment snhould work and the [<unknown>] nickname
6900 should appear no more.
6902 The silc_server_replace_id function that receives the Replace ID
6903 payload now sends the NICK_CHANGE notify type also in the file
6904 silcd/packet_receive.c
6906 * Changed WHOIS and IDENTIFY command to support the maximum amount
6907 of arguments defined in protocol specs (3328 arguments). This
6908 fixed a bug that caused problems when there were more than three
6911 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Added extra parameter, command identifier, to the
6914 silc_client_send_command so that explicit command identifier
6917 Changed that ID list routines uses specific command identifier
6918 when sending WHOIS/IDENTIFY requests to the server so that they
6919 can be identified when the reply comes back.
6921 Affected files lib/silcclient/command.[ch],
6922 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6924 * Added `sender' argument to silc_server_packet_send_to_channel
6925 to indicaet the sender who originally sent the packet to us
6926 that we are now re-sending. Ignored if NULL. Affected file
6927 silcd/packet_send.[ch].
6929 * Added some server statistics support in silcd/server_internal.h
6930 SilcServerStatistics structure and around the server code. Also
6931 send some nice statistics information when client is connecting
6934 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Fixed channel ID decoding in server's JOIN command reply in
6937 silcd/command_reply.c
6939 * Fixed braodcasting of replace ID payload to not to send it if
6940 we are standalone server in silcd/packet_receive.c.
6942 * Fixed all channel message sending routines to not to send
6943 packets to clients that has router set, since they are routed
6944 separately in the same function earlier. Affects file
6945 silcd/packet_send.c and all channel packet sending functions.
6947 * In USERS reply, res_argv[i] are not allocated, the table
6948 is allocated. Thus changed that free the table, not its
6951 * In server's whois_check and identify_check if the client is
6952 locally connected do not send any WHOIS commands - they are not
6955 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * Fixed some minor bugs in client when sending WHOIS command. The
6958 arguments was in wrong order.
6960 * Removed statis function add_to_channel from server in
6961 silcd/command.c that was previously used with the joining but
6964 * Tested USERS command in router environment successfully with two
6965 routers, two servers and two clients.
6967 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6969 * Reorganized the USERS command and command reply in client library
6970 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6971 When the command is given by user we register a pending command
6972 callback that will reprocess the command after the reply has been
6973 received from the server. When reprocessing the packet we then
6974 display the information. Thus, the USERS information is displayed
6975 now in the command callback instead of in the command reply
6976 callback. The processing of the command is same as previously
6977 when server has sent the command reply in the JOINing process.
6979 * Added to USERS command in silcd/command_reply.c to join the client,
6980 we didn't use to know about, to the channel after we've created
6981 a client entry for it. Also, for clienet we did know already still
6982 check whether it is on the channel or not and add it if not.
6984 * Removed silc_server_command_join_notify as the function and its
6987 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6989 * Changed the client's pending command handling to the same as the
6990 server's pending command handling. It is also now possible to
6991 execute command reply functions from other command reply
6992 function as the function callbacks for commands and command
6993 replies are one and same. The pending commands are not static
6994 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6995 in client connection context. Thus, pending commands are server
6996 connection specific as it is convenient.
6998 Changed the function silc_client_command_pending and
6999 silc_client_command_pending_del and added new function
7000 silc_client_command_pending_check. Removed the
7001 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7004 * Added cmd_ident, current command identifier, to the client
7005 connection context in lib/silcclient/client.h to keep track on
7006 command identifiers used in command sending. Client's command reply
7007 function handling now supports the mandatory command identifiers.
7009 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7010 funtions in client to fully support pending command callbacks.
7012 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7013 as one of the arguments to the application in the command reply
7016 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7017 before first releasing SILC but came back. Now it is removed again
7018 and should come back nomore. The FORWARDED flag was used only
7019 by the JOINing procedure by forwarding the command packet to router.
7020 Now, the JOINing procedure has been changed to more generic (due
7021 to various router environment issues) and FORWARDED is not needed
7022 anymore for anything. The protocol specification is yet to be
7025 Now, removed silc_server_packet_forward from server and the flag
7026 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7028 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7030 * Renamed NAMES command to USERS command. The NAMES was named that
7031 due to historical reasons. Now it is renamed. Also, rewrote
7032 parts of the USERS command. The nickname list is not sent anymore
7033 by the server. Only Client ID and mode lists are sent in the USERS
7034 command. Changed this also to the protocol specification.
7036 The client now resolves the names and stuff after it receives
7037 the USERS list from the server when joining to the channel.
7039 * WHOIS and IDENTIFY commands has been changed to support multiple
7040 Client ID's per command. One can now search for multiple users
7041 in the network by sending only one WHOIS or IDENTIFY command.
7042 Changed the code and the protocol specifications.
7044 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7045 uses silc_server_command_whois_parse to parse the request. */
7047 * If normal server, do not parse the WHOIS and IDENTIFY requests
7048 before sending it to the router. Saves some time.
7050 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Fixed JOIN command on client library. Wrong number of arguments
7053 used to crash the client.
7055 * Added silc_server_channel_has_global function to check whether
7056 channel has global users or not.
7058 * Added silc_server_channel_has_local function to check whether channel
7059 has locally connected clients on the channel.
7061 * The silc_server_remove_from_one_channel now checks whether the
7062 channel has global users or not after given client was removed from
7063 the channel. It also checks whether the channel has local clients
7064 on the channel anymore. If it does not have then the channel entry
7065 is removed as it is not needed anymore.
7067 * The silc_server_notify now checks on JOIN notify whether the joining
7068 client is one of locally connected or global. If it is global then
7069 the channel has now global users on the channel and that is marked
7070 to the channel entry. Also, it now saves the global client to
7071 global list who is joining and JOINs it to the channel. This is
7072 for normal server, that is.
7074 Changed silc_server_send_notify_on_channel,
7075 silc_server_packet_relay_to_channel and
7076 silc_server_packet_send_to_channel check if we are normal server
7077 and client has router set (ie. global client) do not send the
7078 message to that client, as it is already routed to our router.
7080 * Implemented LEAVE notify type handling in silc_server_notify
7083 * Tested LEAVE command in router environment successfully. Tested
7084 with two routers, two servers and two clients.
7088 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7090 * Implemented SIGNOFF notify type handling in silc_server_notify
7093 * silc_server_remove_id now removes the client entry from all channels
7094 it has joined and thusly sends SIGNOFF notify type.
7096 * Rewrote the NAMES list generation in server by removing two excess
7097 loops. The lists are created now inside one loop.
7099 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * silc_server_remove_channel_user checks now also global list
7102 for channel and client.
7104 * silc_server_new_channel_user checks now both local and global
7105 list for channel and client. Fixed a bug in client id decoding.
7106 Used to decode wrong buffer.
7108 * silc_server_channel_message checks now both local and global
7109 list for channel entry.
7111 * Tested channel joining (hence JOIN) in router environment
7112 successfully. Tested with two routers, two servers and two
7115 * Tested channel message sending in router environment successfully.
7117 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Added silc_server_save_channel_key into server.[ch] to save the
7120 received channel key in Channel Key payload processing. It is
7121 also used in JOIN command reply handling.
7123 Equivalent function silc_client_save_channel_key added into
7124 client.[ch] into client library.
7126 * Changed JOIN command reply to send information whether the channel
7127 was created or not (is existing already) and the channel key
7128 payload. Changed protocol specs accordingly.
7130 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7131 the request was sent by ID and not by nickname. Crashed on
7134 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7137 now correctly save the received data.
7139 * silc_server_free_sock_user_data now notifies routers in the
7140 network about entities leaving the network.
7142 At the same time implemented functions silc_server_remove_id
7143 and silc_server_send_remove_id to receive and send REMOVE_ID
7144 packets. The packet is used to notify routers in the network
7145 about leaving entities. The ID removed will become invalid in
7148 * Added function silc_idlist_del_server into server. Removes and
7149 free's server entry from ID list.
7151 * silc_server_private_message function now checks, if we are router,
7152 that the destination ID really is valid ID, naturally.
7154 * In router when NEW_ID packet is received (for new client) the
7155 hash of the Client ID is saved in the ID Cache but the
7156 client->nickname is set to NULL, instead of putting the hash
7159 IDENTIFY command now also checks that client->nickname must be
7160 valid. If it is not if will request the data from the server who
7161 owns the client. Added new function
7162 silc_server_command_identify_check.
7164 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7165 to set the command to already allocated Command Payload.
7167 * Tested private message sending in router environment with two
7168 routers, two servers and two clients. Fixed minor bugs and now
7171 * Fixed segfault from client's NAMES command. Used to crash if
7174 * Forwarded packets must not be routed even if it is not destined
7175 to the receiver. Changed server code comply with this.
7177 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Added `require_reverse_mapping' boolean value to ServerParams
7180 structure. If TRUE (not default) the server will require that
7181 the connecting host has fully qualified domain name.
7183 If the reverse mapping is not required and hostname could not be
7184 found the IP address is used as hostname.
7186 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7188 * Implemented version string checking to both client and server.
7189 The check is incomplete currently due to the abnormal version
7190 strings used in development version of SILC.
7192 * Changed all command functions in server to use the new
7195 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Changed char *data to unsigned char *data in ID Cache system to
7198 support binary data as ID Cache data. Changed code to support
7199 binary data in lib/silccore/idcache.c.
7201 * Renamed silc_server_packet_relay_command_reply to
7202 silc_server_command_reply as it is normal packet receiving
7203 function. Rewrote the function to accept command replys for
7204 servers and not only for clients.
7206 * Mark remote router always as registered server if we are connecting
7207 to it. Otherwise, commands sent by the router to us are ignored.
7209 * All ID List find routines now returns the ID Cache Entry pointer
7210 as well if requested.
7212 * WHOIS command works now in router environment, tested with two
7213 routers, two servers and two clients.
7215 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7216 in router environment (as it is almost equivalent to WHOIS) but
7217 hasn't been tested thoroughly. Added new functions:
7219 silc_server_command_identify_parse
7220 silc_server_command_identify_send_reply
7221 silc_server_command_identify_from_client
7222 silc_server_command_identify_from_server
7224 * Disabled route cache adding because adding two different ID's with
7225 same IP replaces the old cache entry thus giving wrong route.
7226 The entry->router->connection is always the fastest route anyway
7227 so route cache may not be needed. Of course, new routes maybe
7228 established after receiving the ID when the entry->router->connection
7229 might not be anymore the most optimal.
7231 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Add route cache for received ID for fast routing.
7235 * Added silc_server_packet_route to route received packet on router
7236 that is not destined to us.
7238 * Renamed silc_server_get_route to silc_server_route_get.
7240 * Added id_string and id_string_len fields into SilcServer to
7241 include encoded ServerID for fast comparing without excess
7242 encoding of the ID's.
7244 * Cleaned up WHOIS command on server side. Added following static
7247 silc_server_command_whois_parse
7248 silc_server_command_whois_check
7249 silc_server_command_whois_send_reply
7250 silc_server_command_whois_from_client
7251 silc_server_command_whois_from_server
7253 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7254 arguments in command replies. All command functions should be
7255 updated to use this macro.
7257 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Minor typo fixes on command reply handling on server.
7261 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Added silc_server_command_add_to_channel internal routine to add
7264 the client to the channel after router has created the channel and
7265 sent command reply to the server.
7267 * Added generic silc_server_send_command to send any command from
7270 * Use static buffer with ID rendering instead of duplicating data.
7272 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * Fixed a channel user mode bug when joining to a channel server gave
7275 everybody channel founder rights, oops.
7277 * We mark ourselves as the router of the incoming server connection
7278 if we are router ourselves. This way we can check in some packet
7279 sending functions whether it is locally connected server. For
7280 incoming router connections we put NULL.
7282 * For router sending packets locally means now always sending the
7283 packet cell wide; to local clients and local servers. For normal
7284 server sending packet locally means sending it to only local
7287 * Fixed the JOIN command to really work in router environment. If the
7288 channel is created it is always created by the router. Router is
7289 also responsible of making the initial joining to the channel,
7290 sending JOIN notify to the sending server and distributing
7291 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7292 does not exist server doesn't do anything else but forward the
7293 command to the router which performs everything.
7295 * Added silc_server_send_channel_key function to send the Channel Key
7298 * Added silc_server_create_channel_key to create new channel key. The
7299 channel key is now re-generated everytime someone joins or leaves
7300 a channel, as protocol dictates. Note: channel->key_len is the
7303 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7306 packet_receive.[ch] to separate packet sending and receiving
7307 routines. The server.[ch] now includes everything else including
7308 actual packet processing (writing and reading data) and other
7311 Renamed silc_server_private_message_send_internal to
7312 silc_server_send_private_message. The routine is still though
7313 used only to relay private messages as server does not send
7314 private messages itself.
7316 Renamed silc_server_new_channel to silc_server_create_new_channel
7317 and added new function sicl_server_new_channel that handles the
7318 incoming New Channel packet. Added also new sending function
7319 silc_server_send_new_channel to send New Channel Payload.
7321 * Added new function silc_server_notify to process incoming notify
7322 packet to the server/router. Server may then relay the notify
7323 to clients if needed.
7325 * Added new function silc_server_new_channel_user to process incoming
7326 New Channel User packet. Router will redistribute the packet and
7327 send JOIN notify to its local clients and locally connected servers
7328 if needed. Normal server will send JOIN notify to its local client
7329 on same channel when received this packet. Added also corresponding
7330 sending function silc_server_send_new_channel_user to sent the
7333 * Added boolean route argument to send_notif_to_channel and
7334 packet_send_to_channel functions to attempt to route the packet
7335 if it is TRUE and send only locally if it is FALSE.
7337 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * silc_server_replace_id now broadcasts the received replace ID
7340 packet if it is not broadcast packet already. The router must
7341 broadcast to inform other routers about changed ID.
7343 * Added backpointer to server's router into SilcServer context in
7344 silcd/server_internal.h.
7346 * Fixed silc_server_packet_broadcast to send correct broadcast
7349 * The channel key is now distributed to the local client as soon
7350 as it is received from the router (in router environment) so that
7351 no other packet may be sent for the channel until client has
7354 * silc_server_remove_channel_user now broadcasts the received
7355 Remove Channel User packet if it is not broadcast packet already.
7356 The router must broadcast to inform other routers about removed
7359 * Added users field into SilcPacketContext that is a reference count
7360 of the context. One can increase the reference count by calling
7361 silc_packet_context_dup which is now changed to just increase the
7362 reference count instead of duplicating the data. The reference
7363 count is decresed by calling silc_packet_context_free that will
7364 free the data after the reference count hits zero.
7366 For now on the packet context and everything allocated into it
7367 (including the raw packet from network) must be freed by calling
7368 the new silc_packet_context_free function. Added also new function
7369 silc_packet_context_alloc that must be used now to allocate the
7370 context. This also means that if a routine is asynchronous from
7371 silc_[client/server]_packet_parse_type the packet context must
7372 be duplicated by calling silc_packet_context_dup. Otherwise it
7373 gets free'd after silc_[client/server]_packet_parse_type returns.
7374 Also, one must remember that if packet is duplicated then its
7375 reference count must be decresed by calling the free function as
7376 many times as it was duplicated.
7378 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7379 from both client and server.
7381 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7383 * Made joining to a channel working in router environment.
7385 * Cleaned up JOIN command on server side and create function
7386 silc_server_command_join_channel internal routine to make the
7389 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7391 * Changed silc_command_pending list to SilcDList. Also, added
7392 `ident' field to SilcServerCommandPending structure to identify
7393 the reply and to call correct callback.
7395 Added silc_server_command_pending_check function to replace the
7396 corresnponding macro. The silc_command_pending list is not
7399 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7400 to set identifier to previously allocated Command Payload. It
7401 is used to set identifier for command when resending Command
7404 * Added silc_command_payload_encode_payload to encode Command
7405 Payload buffer from SilcCommandPayload structure.
7407 * Added silc_argument_payload_encode_payload to encode Argument
7408 payload buffer from SilcArgumentPayload structure.
7410 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Changed WHOIS command to support router connection on server side.
7413 The whois request is always sent to router unless the server is
7414 standalone server. After server has received the reply from the
7415 router will it send the reply to the client.
7417 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7418 broadcast received broadcast packet. The function is used only
7419 by router. The broadcast packet is always sent to the router's
7422 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7423 render given ID to printable string, for log files for example.
7425 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7427 * Made basic router to router connections working. At least they
7428 can now connect to each other but nothing really works the way
7429 they are supposed - yet.
7431 * Added new initiator token to RouterConnection configuration
7432 file in silcd/serverconfig.[ch]. It is used to tell whether we
7433 are the initiator to the remote router or whether we'll expect
7434 the other end to connect.
7436 * Moved registering of listener task to silc_server_init, hence
7437 the server starts listenning as soon as it is run, even if it
7438 does not have connections to other routers. Let's see how well
7441 * Changed default connection retry timeouts for more suitable in
7444 * Removed cipher and such arguments from silc_idlist_add_client
7445 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7446 Added new function silc_idlist_add_data to add the keys and stuff
7449 * Added SilcIDListData structure and added it to SilcClientEntry
7450 and SilcServerEntry as their first field in the structure. This
7451 way we can explicitly cast the ID entries to the SilcIDListData
7452 structure and get common data for the entries. In past, we had
7453 to first check what type of connection it is and then cast it to
7454 correct ID entry type. Now, we can directly cast the opaque
7455 pointer to the SilcIDListData (no matter what ID entry it actually
7456 is) and get the data needed.
7458 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7461 in some circumstances even if threre were timeout tasks, though not
7462 IO tasks, but tasks anyway. Now fixed.
7464 * Defined SilcServerConnection structure to hold connection specific
7465 stuff about directly connected servers and routers. The definition
7466 is currently in silcd/server_internal.h. I thought about having
7467 a bit more important role fro this struct but for now it is used
7468 only when connecting to other server (or router actually).
7470 * Added connecting retry support in server when connecting to
7471 router(s). The retry feature implement exponential backoff
7472 algorithm. Also, added SilcServerParams structure to hold default
7473 parameters for server. For now, it include these retry settings
7474 and are hard coded. After server is moded to be as Silc Server
7475 Library this structure will be more important.
7477 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Changed client librarys channel->clients table to SilcList and
7480 changed code accordingly.
7482 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7484 * Changed client's channel table to SilcList and changed code
7485 accordingly. Also changed SilcChannelClientEntry to include back-
7486 pointer to the channel so that client entry can use that structure
7487 as list as well and we have fast cross-reference to the channel.
7488 This change dramatically decreased the complexity of channel
7489 handling with client entry and vice versa (removed one extra
7490 loop when searching for channel entry from many functions).
7492 * Changed server->sim from table to SilcDList and changed code
7495 * NAMES command can now be used from user interface. It will show
7496 the user list on the channel, neatly.
7498 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7499 Code now saves realname of the user if it becomes available.
7501 * Renamed configure.in to configure.in.pre and made ./prepare
7502 script to automatically add correct version string to
7503 configure.in which it creates from configure.in.pre.
7505 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7507 * NAMES command reply now shows users mode with the nickname when
7510 * Moved silc_client_ch[u]mode[_char] functions from
7511 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7512 place sucks, they are utility functions and should be in some
7515 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7517 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7520 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7524 * Added TRQ (efficient deque and list library) into lib/trq. This is
7525 a very good list library that is currently used in the SILC. Defined
7526 SilcList API over the library because I didn't like the API very
7527 much. See lib/trq/silclist.h for the API and examples of how to
7528 use the API. Fixed various places in the code to use the new
7529 SilcList API. The SilcList is meant for lists that has a structure
7530 already defined as a list. It is not suitable to add just some
7531 context to the list (in TRQ, the context is the list actually).
7533 So, I defined SilcDList that can be used for the purpose where
7534 predefined list structure does not exit. This can be used as
7535 such list. Now some context just can be added to the SilcDList.
7536 Currently this list is not used in the SILC just yet, though there
7537 are a lot places where this can replace dynamically allocated
7538 tables and I will fix these places, later, to use SilcDList.
7539 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7540 and use TRQ internally).
7542 Also fixed some annoying warning messages that the original TRQ
7543 code generated. Also minor changes to TRQ's Makefile.in.
7545 * Added support for querying by Client ID to both WHOIS and
7546 IDENTIFY commands into server, as required by the protocol.
7548 * Removed method function pointers from SilcBuffer structure. They
7549 weren't used to anything and just increased the context size for
7550 no good reason. This change also made silc_buffer_alloc and
7551 silc_buffer_free functions inline functions.
7553 * Disabled command flooding detection support until it's fixed so
7554 that it accepts commands in but does not execute them more than once
7557 * Added silc_net_localhost(), to return local hostname, into
7558 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7559 that must be initialized before calling silc_client_init.
7561 * Added new function: silc_server_send_notify_on_channels to send
7562 notify messages to all channels client has joined. It is assured
7563 that the message is sent only once per client.
7565 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7566 lib/silcutil/silcutil.[ch] as silc_format function. The new
7567 function is generic and is used by server as well, not only by
7568 the logging routines.
7570 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7571 the provided version string was not acceptable. Added new function:
7572 silc_ske_check_version into lib/silcske/silcske.h. The function
7573 must be implemented by the application (client or server) and it
7574 does not reside in the SKE library. The function checks the version
7575 string remote end sent.
7577 * Added back pointers (to opaque context and to SilcSocketConnection)
7578 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7580 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7581 duplicate packet context structure.
7583 * Changed `notify' client operation to send same arguments as client
7584 receives from server except for ID's. ID's are mapped to correct
7585 ID entry and that is returned. Also, if channel entry is not sent
7586 by server but the notify is for channel the channel entry is sent
7587 to application (otherwise application doesn't know that it is for
7588 channel (library gets it from packet's Destination ID)).
7590 * Added silc_client_remove_from_channels into client library to
7591 remove a client from all channels it has joined to. Used when
7592 received SIGNOFF notify from server. Added also new function
7593 silc_client_replace_from_channels to replace old ID entry with
7594 new ID entry on all channels. Used when received NICK_CHANGE
7597 * Fixed ID Cache list handling in silc_idlist_get_client in
7598 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7599 to get (or query) client by ID.
7601 * Updated TODO list.
7603 * Added connection authentication status message defined by the
7604 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7605 support for these into the code in client and server side.
7607 * Added generic function silc_client_send_command to send any command
7608 with variable argument list. Application should use this function
7609 to send commands if the command functions provided by the library
7610 does not suite for the application's user interface needs.
7612 * Added new `failure' client operation. Application is notified about
7613 received failure packet if client is executing a protocol. In this
7614 case the protocol's execution has failed.
7616 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7617 is required by the protocol.
7619 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7620 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7623 * Added status flag to SilcSKE object to indicate realtime status
7624 of the SKE protocol.
7626 * Application receives now exactly same command reply arguments as
7627 the library receives from server. However, if ID is received the
7628 corresponding ID entry is returned to the application (eg. Client
7629 ID is mapped to correct SilcClientEntry entry and that is returned).
7630 Changed command_reply client operation due to this change.
7632 * Changed all ID's in commands and in command replys as ID Payloads.
7633 Change affected both client and server side codes.
7635 All ID's sent in SILC network (with execption of ID's in SILC
7636 Packet header) are sent in ID Payload to support variable length
7639 * Server now notifies nick changes and notifies all clients on
7640 the channels about the new nickname (about the new Client ID,
7643 * Implemented CMODE command to change channel modes. Supports all
7644 channel modes defined by the protocol specs except ban and invite
7645 lists. (Also, private channel key mode is supported but support for
7646 setting private channel key in client is missing, thus, this mode
7647 has no effect on client side (except that server requires that the
7648 client uses private channel key and normal channel traffic does not
7651 Also, invite mode works per se, but INVITE command does not work
7652 yet correctly, so you can set channel as invite only channel but
7653 inviting clients to the channel does not work (it is yet to be
7654 thought what's the best way to do it).
7656 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7657 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7658 Implemented CUMODE command to change user's mode on the channel.
7659 Supports all modes defined by the protocol specs.
7661 * Added NAMES command reply to return users modes on the channel.
7663 * Removed unnecessary and slow ciphers from lib/silccrypt.
7665 * Set SO_KEEPALIVE option to connection sockets by default.
7667 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7669 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7670 redefined the Notify Payload into protocol specs.
7672 * Added silc_id_payload_parse_id to get ID directly from raw
7675 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7678 accept searching by Client ID as well.
7680 * Added support for LEAVE and SIGNOFF notify types in client library.
7682 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7683 to parse ID Payload from raw data.
7685 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Added flags parameter into silc_ske_assemble_security_properties
7688 function in lib/silcske/silcske.[ch].
7690 * Changed notify client operation to fit better for notify messages
7691 sent by server. The notify payload received from server is now
7692 passed to the application (after parsing it to SilcNotifyPayload).
7693 It is application's responsibility to retrieve the arguments
7694 from the payload and show the message the way it wants. The message
7695 sent by server is implementation specific.
7697 * Changed public keys to comply with the protocol specification.
7698 Old public keys are not supported anymore and are not compatible.
7700 * Removed nickname from Channel Payload as the latest draft removed
7701 it. The client must resolve the nickname from the NAMES command
7702 reply received when it joined the channel.
7704 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7706 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7708 * Fixed some errors in protocol specification drafts.
7710 * Created lib/silccore/silcnotify.c to implement Notify Payload
7711 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7712 generic payloads described by protocol specifications. The file
7713 includes implementations for ID Payload and Argument Payload.
7715 * Changed Command Payload implementation to use the new Argument
7716 Payload. Changed command_xxxx_payload to command_payload_xxxx
7717 to comply with SILC coding conventions.
7719 * Added suppport for Argument Payload handling in Notify Payload
7720 implementation as protocol requires it. Added the new support
7721 into server and client lib as well.
7723 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7725 * Added support for multiple nicknames on same channel. [n] is
7726 added locally to the nickname if there are more than one same
7727 nicknames on the channel.
7729 * Server now sends all nicknames that matched WHOIS request.
7730 Client also shows the list received from server.
7732 * Added TOPIC command to client side. User can now set and show
7733 current topic on channel.
7735 * Added MOTD command to client and server. Also, server sends the
7736 motd when client connects to the server.
7738 * Changed version strings to comply ISO 8601.
7740 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7742 * Fixed protocol error handling in client library. It should now
7743 cope even if the SKE fails for some reason.
7745 * Made new protocol specification drafts for submitting to IETF.
7747 * Implemented TOPIC command to server in silcd/command.c.
7749 * Added two new notify types into lib/silccore/silcnotify.h:
7750 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7751 notify nickname change and topic setting/change on a channel.
7753 * API change of command_reply operation in client library. The
7754 application gets now the status type received from server as well.
7756 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7758 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7760 * Cras fixed and optimized the packet handling even further and
7761 it should work now. Minor change to the prototype of function
7762 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7764 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7766 * Added new function into lib/silcutil/silcschedule.[ch]:
7767 silc_schedule_with_fd to select() a specified fd. The function
7768 returns after timeout expires or data arrives or goes. The
7769 function is used by packet routines to wait that all data is
7770 received from network.
7772 * Fixed data reading from network in lib/silccore/silcpacket.c.
7773 The code now assures that all data is read from the fd and then
7774 continues packet processing. This was a bug fix since the code
7775 used to drop some data in some circumstances.
7777 * Added new function into lib/silcclient/client.[ch]:
7778 silc_client_start_key_exchange to start key exchange after
7779 connection has been established to server. The code internally
7780 now uses this funtion but its main purpose was to provide it
7781 for applications that perform their own connecting. After
7782 application has created a connection it merely calls this
7783 function to start the key exchange between client and server.
7784 The library takes care of everything else after that.
7786 Updated also lib/silcclient/README to explain the usage of
7789 * Do not send to application information that connection has
7790 been established. Application gets notified it by connect
7793 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7795 * Applied cras's patch to add silc_schedule_one function. The
7796 function runs scheduler once and returns.
7798 * Fixed the scheduler after cras messed it up. The timeout
7799 handling works now as it's supposed to work.
7801 * Added into lib/silccore/ silcnotify.h to include notify
7802 message types support. Changed silc_server_send_notify*
7803 functions, in server.[ch], to support those new notify types.
7804 Added the support for the notify types into client library,
7805 as well. Added new notify client operation into ops.h in
7808 * Changed silc_server_packet_send_to_channel to send normal
7809 packets instead of just channel message packets. The function
7810 is now used to send the notify packets to channels. It is not
7811 used to send channel message packets anymore, as server never
7814 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7815 va_arg()s as it seems to require it nowadays. I guess, if SILC
7816 is compiled with older va_arg() the new code should work anyway.
7818 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7820 * Splitted core library. Core library (lib/silccore) includes
7821 now only SILC protocol specific core (and common) components.
7822 Created new utility library (lib/silcutil) that includes more
7823 generic purpose stuff. The stuff for util library was taken
7824 from the old core library. This was minor and easy split.
7826 * Created SILC Client Library (lib/silcclient) that includes
7827 implementation of the SILC client without user interface. This
7828 was major move from silc/ directory. The code has been changed
7829 so that it is transparent towards the user interface. The
7830 silc/ directory includes now the same user interface as before
7831 and it uses the new client library. Read lib/silcclient/README.
7832 Basicly, the client library performs everything else related
7833 to SILC except user interface handling. Also, configuration
7834 files are considered to be part of user interface and library
7835 does not handle them.
7837 This change also changed a lot of structures, function naming etc.
7838 Most important change was that SilcClientWindow object was
7839 renamed to SilcClientConnection in the client library. Created
7840 also new file lib/silcclient/ops.h. Also added new files
7841 silc/local_command.[ch] and silc/client_ops.[ch].
7843 All these changes were made to make it easier for user interface
7844 designers to create what ever user interface for the SILC client
7847 It is also expected that the server will be moved to lib
7848 directory as well and SILC Server Library will be created;
7849 sometimes in the future.
7851 * Removed Local commands from lib/silccore/silccommand.h as
7852 they are application specific and new client library does not
7853 handle any of those anymore.
7855 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7856 old client implementation in silc/.
7858 * Added support for callback functions in SILC_LOG_* macros.
7859 Application can now set its own callbacks that will be called
7860 instead of using the default functions that will always print
7861 the debug messages to stderr (or stdout). Also, debugging can
7862 now be disabled by setting silc_debug to FALSE and re-enabled by
7863 setting it to TRUE. Note, that logging will still work even
7864 if debugging is disabled.
7866 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7867 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7868 silc_log_reset_debug_callbacks.
7870 * To enable debugging in silc client one must give now -d
7871 option on command line.
7873 * Changed silc_schedule_init to automatically allocate task queues
7874 if they are not allocated before calling it.
7876 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7878 * Added GMP 3.1 into math library.
7880 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7882 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7883 a channel in SILC network. The packet is used by servers and
7884 routers to notify other routers that user has left a channel.
7885 This little feature was missing until now. Added the feature
7886 to protocol specification as well.
7888 Added functions: silc_server_send_remove_channel_user and
7889 silc_server_remove_channel_user into server.[ch].
7891 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7892 lib/silccore/silcpacket.h. However, they are not implemented
7895 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Fixed joining to a channel and sending channel messages
7898 between server and router. The channel message sending should
7899 now work inside a cell.
7901 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7903 * Fixed the private message sending between server and router.
7904 The private message sending should now work inside a cell.
7906 * Added silc_server_replace_id into server.[ch] to replace
7907 existing ID in the SILC network.
7909 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7910 and silc_idlist_replace_server_id into idlist.[ch] in server.
7912 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7914 * Fixed the server to server connections. Server can again now
7915 connect to router. Router to router connections probably does
7918 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7920 * Added dynamic protocol registering support. Now protocols can
7921 registered and unregistered on the fly. Patch by cras.
7923 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7925 * Added lib/contrib directory to hold routines that some platforms
7926 don't have but are needed by SILC.
7928 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7929 into lin/contrib to provide getopt() and getopt_long() for
7930 those who don't have it.
7932 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7934 * Added AWAY command to client. When away message is set and
7935 client receives a private message packet the client automatically
7936 replies to the sender with the away message.
7938 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7939 bug seemed to be the cause of recent problems when compiling
7942 * Added version detection support to SKE protocol specification
7943 and added the new changes to the SKE implementation as well.
7944 There were other minor changes in the SKE protocol as well.
7946 Many changes in lib/silcske/silcske.[ch] and in
7947 lib/silcske/payload.[ch].
7949 * Added ^U functionality, clear input line. Patch from cras.
7951 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7953 * Mainly small bugfixes on core library. Fixed some debugging
7954 logging and buffer overflow in silclog.c.
7956 * Updated config.sub and config.guess on the distribution tree.
7958 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7960 * Added command lagging support in server. Client may execute
7961 commands now only once in two seconds.
7963 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7965 * Optimized packet reception. MAC computation and checking is now
7966 also more optimized. A lot previously duplicated code is now
7967 used as generic by both client and server.
7969 * Fixed key pair generation in clientutil.c
7971 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Added into lib/silccore/silcbufutil.[ch] new function;
7974 silc_buffer_realloc.
7976 * Moved generic packet sending/encryption functions to
7977 lib/silccore/silcpacket.[ch] from client and server. Some
7978 rewriting of the functions.
7980 * Moved all generic packet reception/decryption functions to
7981 lib/silccore/silcpacket.[ch] from client and server. The
7982 packet processing is now much cleaner in both client and server.
7983 These were major changes in both client and server.
7985 * Created many common functions in server to do packet sending.
7986 Previously code were duplicated a lot, this has been removed
7989 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7991 * Rewrote major parts of the ID cache system. Don't know
7992 whether it is better now or not but at least the API is more
7995 * Major rewrite on ID cache stuff on client because of the ID
7996 cache API changes. Added idlist.c to client.
7998 * Also major rewrite on ID cache stuff on server as well.
7999 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8000 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8001 in hand, instead they are all put into the ID cache system now.
8002 All server_idlist_* routines uses ID cache now instead of
8003 traversing its own lists (those lists does not exist anymore).
8004 SilcIDList though still exists. Also, SilcXXXEntry's are

8009 * Finally made the SKE implementation compliant to the protocol
8010 specification. All mp integers are now binary encoded as
8011 opposed being HEX encoded.
8013 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8016 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8017 functions: silc_[encode/decode]_pem. Also added function
8018 silc_encode_pem_file to PEM encode with newlines ('\n') for
8021 * SILC public keys are now encoded either PEM or binary. Same
8022 option is for private keys as well. By default private keys
8023 are binary encoded and public keys PEM encoded. Silly HEX
8024 encoding were removed.
8026 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8027 function to create fingerprints.
8029 * Fixed a bug in SHA1; does not change the original data anymore.
8031 * Partly implemented INFO command on client and server side.
8032 Fixed CLEAR command. Changes to SERVER command; show current
8033 server(s) when giving command without arguments. Added
8034 VERSION command to client.
8036 * Added check to server that unregistered connections cannot
8037 execute commands (unless it is specificly allowed).
8039 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8041 * Fixed screen refresh.
8043 * Fixed channel joining bug from client. On some circumstances
8044 client tried to join to a channel it had already joined.
8046 * Added public key verification process into client's protocol.c.
8047 The client now verifies the public key from user and saves
8048 it into ~./silc/serverkeys/ directory.
8050 Added into: clientutil.[ch]: silc_client_verify_server_key.
8052 * Changed SKE protocol's silc_ske_initiator_finish function
8053 to accept callback function that verifies the received public
8054 key. Removed old silc_ske_verify_public_key function.
8056 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8058 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8059 silc_pkcs_private_key[_data]_set.
8061 * Made the password and public authentication more cleaner in
8062 server's protocol.c.
8064 * Removed historic and obsolete protocol `channel_auth' from
8065 both client and server.
8067 * Removed wrong way of sending command status messages from
8068 server to client in server's command.c. The old way violated
8069 protocol specification.
8071 Changes to silccore/silccommand.[ch]: removed
8072 silc_command_encode_status_payload -> not needed anymore,
8073 changed silc_command_encode_payload_va to accept extra
8074 argument on variable argument list. The argument type must
8075 now be provided to the function. Also, added new function:
8076 silc_command_encode_reply_payload_va which is same as
8077 normal command_encode_payload_va except command status type
8078 is provided as extra argument.
8080 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8082 * Added ~./silc directory handling. The directory includes the
8083 public and private keys for the client.
8085 Added silc_client_check_silc_dir, silc_client_create_identifier
8086 and silc_client_load_keys.
8088 * Implemented SILC protocol compliant public key. Added public
8089 and private key saving to and loading from files.
8091 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8092 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8093 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8094 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8095 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8097 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8098 silc_pkcs_load_[public/private]_key.
8100 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8102 * Added silc_server_get_route (route.[ch]) to get connection
8103 data for the fastest route for given ID.
8105 * Implemented INVITE command on client and server. The command
8106 were re-defined in the SILC Protocol Specification and the
8107 implementation now complies with the specification.
8109 * Implemented PING command on client and server.
8111 * Implemented NAMES command on client and server. The server side
8112 supports currently only normal server not router server yet.
8113 Some changes to NAMES definition in SILC protocol specification.
8115 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8117 * Implemented LEAVE command on client and server.
8119 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8120 again. This change was made to the protocol as well. Server
8121 should not violate the protocol specification anymore.
8123 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8125 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8126 was tested. SOCKS4 was not but should work anyway.
