1 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added the silc_client_del_client to remove the client from
4 all channels as well. Affected file lib/silcclient/idlist.c.
6 * Fixed the client library to correctly remove the client
7 from all channels when the client entry is being destroyed.
8 Affected file lib/silcclient/client_notify.c, command.c.
10 * Added auto-nicking support to the client library. If the
11 applicatio now sets client->nickname it will be sent to the
12 server after connecting by the library. This way for example
13 SILCNICK (or IRCNICK) environment variables will have effect
14 and always change the nickname automatically to whatever
15 it is wanted. Affected file lib/silcclient/client.[ch].
17 * Renamed silc_server_command_bad_chars to the
18 silc_server_name_bad_chars and moved it to the
19 silcd/server_util.[ch]. Added also new function
20 silc_server_name_modify_bad to return nickname that
21 includes bad characters as new nickname without those
22 bad characters. This check and modify is now used in
23 silc_server_new_client when the username is initially set
24 as nickname, so it must be checked to be valid nickname.
25 Affected file silcd/packet_receive.c.
27 * The nickname length is now taken from the packet for real
28 and not trusted to strlen() since it clearly can return
29 wrong length for nickname including bad characters. This
30 also applies to channel names. Affected file silcd/command.c.
32 * Removed the lib/silcsilm/modules directory. Modules are now
33 compiled into the lib/silcsim. Fixed the copying of the
34 modules to follow symbolic links in Makefile.am.pre.
36 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Fixed silc_string_regexify list creation. Fixes bugs with
39 BAN and INVITE commands in server. The affected file is
40 lib/silcutil/unix/silcunixutil.c.
42 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
44 * Removed the command destructor entirely from the server's
45 command and command reply routines. It is not needed, and
46 its usage was buggy and caused crashes. Affected files are
47 silcd/command[_reply].[ch].
49 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
51 * Cancel protocol and NULL sock->protocol if timeout
52 occurred during protocol. Affected file silcd/server.c.
54 * Cancel protocol timeouts always before calling the final
55 callback, to assure that after final callback is called
56 no other state will be called for the protocol anymore.
57 Affected file silcd/protocol.c.
59 * Print error log if incoming connection configuration could
60 not be found. Affected file silcd/server.c.
62 * Fixed JOIN command to correctly save the founder mode
63 to the client on normal SILC server, when the channel
64 was created by the router. Affected file silcd/command.c.
66 * Fixed LIST command (hopefully) to send correct reply
67 packets. Affected file silcd/command.c.
69 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
71 * The silc_packet_receive_process now returns FALSE if the
72 read data was invalid packet, and TRUE if it was ok.
74 The server now checks that if unauthenticated connection
75 sends data and its processing fails the server will close
76 the connection since it could be a malicious flooder.
78 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
80 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
82 * Make sure the warning about error opening a log file is
83 printed only once and not everytime it fails (produces
84 too much useless log). Affected file lib/silcutil/silclog.c.
86 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
88 * Made the silc_server_daemonise() function more readable.
89 Affected file silcd/server.c.
91 * Pid file is now optional, the user may comment it out from
92 the config file. Removed define SILC_SERVER_PID_FILE, we
93 don't need a default any longer. Affected file
94 configure.in.pre, lib/Makefile.am.pre.
96 * Make some use of the pid file. The server now dies at startup
97 if it detects a valid pid file on his path. The server would
98 die anyway in this circumstance, because of the bind() failure.
99 Affected file silcd/silcd.c.
101 * No longer compiling lib/dotconf.
103 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
105 * Fixed JOIN command parsing not to crash. Affected file
106 lib/silcclient/command.c.
108 * Fied the NICK_CHANGE notify to add the new client entry
109 even it is resolved. This removes an <[unknown]> nick
110 thingy bug in the client. Affected file is
111 lib/silcclient/client_notify.c.
113 * Do not try to allocate 0 bytes (efence does not like it)
114 in lib/silccore/silccomand.c when encoding payload.
116 * Do not take IRCNICK as nickname in Irssi SILC client since
117 it is not possible to set nickname before hand connecting
118 the server (TODO has an entry about adding auto-nicking
121 * Changed the silc_server_command_pending to check whether
122 there already exists an pending entry with the specified
123 command, command identifier and pending callback. This is
124 to fix IDENTIFY and WHOIS related crashes that may register
125 multiple pending commands with same identifier. Affected
126 file silcd/command.c.
128 * Fixed the server to reconnect to the router even if it
129 was already reconnecting and EOF was received. This to
130 fix a possibility that the server wouldn't ever try to
131 auto-reconnect to the router. Affected file silcd/server.c.
133 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
135 * Fixed the server's password authentication to use the
136 length of the locally saved password, and not the one
137 sent in the packet. Affected file silcd/protocol.c.
139 * Fixed same password authentication problem in the
140 Authentication Payload handling routines in
141 lib/silccore/silcauth.c.
143 * Yet another password authentication problem fixed with
144 channel password handling in silcd/command.c.
146 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
148 * If first character of string in silc_parse_userfqdn is '@'
149 then do not parse it. Affected file is
150 lib/silcutil/silcutil.c.
152 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
154 * Fixed minor bug in IDENTIFY command reply sending, which
155 caused various weird problems during JOIN when it was
156 resolving names for users. Affected file silcd/command.c.
158 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
160 * Fixed the IDENTIFY command reply sending to chech better valid
161 clients. It was possible to send incomplete list of replies.
162 Affected file silcd/command.c.
164 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
166 * Added silc_client_command[s]_[un]register functions now to
167 dynamically register the commands in client library. Removed
168 the static table of commands. This allows the client library
169 to call commands without causing the application to know about
170 what commands library has called.
172 Removed the INFO command reply kludge to detect when the command
173 was called by library. Now library use its own command reply
174 function for INFO command.
176 Added function silc_client_command_call to call a command.
177 Application can use it to call command, not access the structure
180 Now all commands that are sent by the client library (not
181 explicitly sent by application) use own command reply functions.
183 Affected files around lib/silcclient/ and in
184 irssi/src/silc/core/.
186 * Fixed the WHOIS command reply sending to chech better valid
187 clients. It was possible to send incomplete list of replies.
189 Fixed the WHOIS and IDENTIFY to send the request to router
190 if normal server did not do it and did not find any results.
192 Affected file silcd/command.c.
194 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
196 * Moved the internal data from SilcClient context into its
197 own file, not accesible to application. Affected files
198 lib/silcclient/client.h and lib/silcclient/client_internal.h,
199 and other files in client library.
201 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
203 * Added doc/examples installation target in Makefile.am.pre.
206 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
208 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
209 commands the found client entry will be removed from the
210 cache, after notifying application about the error. Affected
211 file lib/silcclient/command_reply.c.
213 * Changed the /MSG to check for exact nickname user gave, and
214 not let `nick' match `nick@host' if it is only one found. Now,
215 user must type the exact nickname (like nick@host2) even if
216 there are no more than one same nicks found. This is to avoid
217 a possibility of sending nickname to wrong nickname since
218 `nick' could match `nick@host'. Affected file is
219 irssi/src/core/silc-servers.c.
221 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
223 * Do not print "you are now server operator" or similar when
224 giving /away command. Affected files are
225 irssi/src/silc/core/client_ops.c, silc-servers.h.
227 * Made the silc_server_command_pending_error_check to send
228 the same command reply payload it received back to the
229 original sender of the command. This way all arguments
230 that was received by the server will be received by the
231 client too. Affected file silcd/command.c.
233 * Added the silc_idcache_add to return the created cache entry
234 to a pointer. Affected file lib/silccore/silcidcache.[ch].
236 * Add global clients to expire if they are not on any channel.
237 This is because normal server will never know if they signoff
238 if they are not on any channel. The cache expiry will take
239 case of these entries. This is done by normal servers only.
240 The affected files are silcd/command_reply.c,
241 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
243 * If server receives invalid ID notification for WHOIS or
244 IDENTIFY and the ID exists in the lists, it is removed.
245 Affected file silcd/command_reply.c.
247 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
248 in client then client entry that it matches is searched and
249 the nickname is printed on the screen for user. Affected
250 file irssi/src/silc/core/client_ops.c.
252 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Use cache entry expire time in the LIST command reply to
255 purge old entries from the cache after the LIST command
256 reply has been received. This way we don't have non-existent
257 entries in the cache for too long. Affected file is
258 silcd/command_reply.c.
260 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
262 * If we are normal server, and we've not resolved client info
263 in WHOIS or IDENTIFY from router, and it is global client,
264 we'll check whether it is on some channel. If it is not
265 then we cannot be sure about its validity and will resolve it
266 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
267 file silcd/command.c.
269 * Search channel by name (if possible) rather than by ID
270 in IDENTIFY command's command reply. Affected file is
271 silcd/command_reply.c.
273 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
275 * Distribute to the channel passphrase in CMODE_CHANGE notify.
276 Updated specs and implemented it. Affected file silcd/command.c,
277 silcd/packet_send.c and silcd/packet_receive.c.
279 * Implemented the <founder auth> payload handling in the JOIN
280 command. If provided all conditions for channel joining
281 except requirement to provide correct passphrase can be
282 overrided by the channel founder. Updated the protocol specs.
283 Affected file silcd/command.c.
285 Added support for founder auth in JOIN command in client
286 library. Fixed the parsing of the JOIN command now to support
287 all options as they should be. The affected file is
288 lib/silcclient/command.c.
290 * Optimized the WHOIS and IDENTIFY commands to send the request
291 to router only if it includes nicknames or other names. If
292 they include only IDs then check the local cache first before
293 routing. Affected file is silcd/command.c.
295 * Added channels topic announcements. Affected file is
296 silcd/packet_receive.c and silcd/server.c.
298 * Fixed the silc_server_send_notify_topic_set to really destine
299 the packet to channel. Affected file silcd/packet_send.c.
301 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
302 library. Affected file lib/silcclient/client_notify.c.
304 * Added UMODE announcements. Affected file silcd/server.c.
306 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
308 * Memory leak fixes in:
310 lib/silcutil/silcsockconn.c
311 lib/silcske/silcske.c
314 lib/silccrypt/silcpkcs.c
315 lib/silccore/silccommand.c
316 lib/silccore/silcidcache.c
321 * ROBOdoc documented the lib/silcske/groups.h file and a
322 bit changed the interface for better.
324 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
326 * Update the client entry context in the ID cache after
327 nick change. Affected file lib/silcclient/command.c.
328 Fixes the CUMODE command when regaining founder privileges,
329 and a little WHOIS problem.
331 * Fixed silc_net_gethostbyname to correctly call the
332 inet_ntop. Affected file lib/silcutil/silcnet.c.
334 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
336 * Added IPv6 support checking to the configure.in.pre, added
337 also --enable-ipv6 option to override the check. Affected
338 file configure.in.pre.
340 * The silc_thread_create now calls the start function
341 directly if threads support is not compiled in. Removes
342 ugly #ifdef's from generic code. Affected files are
343 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
345 * Added silc_net_gethostby[name/addr]_async to asynchronously
346 resolve. Affected files are lib/silcutil/silcnet.[ch].
348 * Added support for rendering IPv6 based server, client and
349 channel IDs. Affected file lib/silcutil/silcutil.c.
351 * Added support for creating IPv6 based server IDs. Affected
352 file is silcd/serverid.c.
354 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
356 * Added silc_net_gethostby[addr/name] into the
357 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
358 routines. Added silc_net_is_ip[4/6]. Affected file is
359 lib/silcutil/unix/silcunixnet.c. All routines that take
360 address as argument now supports both IPv4 and IPv6 addresses.
362 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
364 * Fixed LIST command reply sending in server. Affected file
367 * Server now sends the kicker's client ID in the KICK notify
368 to the kicked client. Affected file silcd/command.c.
370 * The client library now parses the kickers client ID and
371 UI displays it. Affected files lib/silcclient/client_notify.c
372 and irssi/src/silc/core/silc-channels.c, module-formats.c.
374 * Made all payload parsing function prototypes consistent.
375 They all take now const unsigned char * and uint32 pair as
376 the payload data instead of SilcBuffer. Changes all around
377 the source tree. Other unsigned char* -> const unsigned char*
378 changes around the tree as well.
380 * Optimized SFTP client and server packet sending not to
381 allocate new buffer for each packet but to recycle the
382 first allocated buffer. Affected files are
383 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
385 * Optimized the SFTP client to use SilcList instead of
386 SilcDList for requests, because it is faster. Affected file
387 is lib/silcsftp/sftp_client.c.
389 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
390 into lib/silccore/silcid.[ch].
392 Renamed silcpayload.[ch] into silcargument.[ch].
394 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
396 * If client entry is deleted with active key agreement
397 session, abort the session.
399 The silc_client_abort_key_agreement now calls the completion
400 callback with new SILC_KEY_AGREEMENT_ABORTED status.
402 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
405 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
407 * Don't use __restrict in older GCC's. Affected file is
408 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
410 * silc_net_localhost now attempts to reverse lookup the
411 IP/hostname. Affected file lib/silcutil/silcnet.c.
413 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
414 command. It can be used to gain founder privileges at
415 the same time when joining the channel.
417 Defined that the SILC_NOTIFY_TYPE_KICKED send the
418 kicker's client ID as well. Updated protocol specs.
420 Defined that the server must send SILC_COMMAND_IDENTIFY
421 command reply with error status to client who sent
422 private message with invalid client ID.
424 Updated the protocol specification.
426 * Added silc_server_send_command_reply to send any
427 command reply. Affected file silcd/packet_send.[ch].
429 * Added silc_id_payload_encode_data to encode ID payload
430 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
432 * The server now send IDENTIFY command reply with error
433 status if client ID in private message is invalid. Affected
434 file silcd/packet_receive.c.
436 * Save the server key file with server's IP address in
437 the filename instead of hostname. The affected file is
438 irssi/src/silc/core/client_ops.c.
440 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
442 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
445 * Added libtool support for compiling shared objects in
446 lib/silcsim. Affected file configure.in.pre and
447 lib/silcsim/Makefile.am. Original patch by cras.
449 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
451 * Pid file configuration, and server's config file fixes
452 patch by toma. Updated CREDITS file.
454 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
456 * Fixed silc_client_channel_message to not try to decrypt
457 the message twice if it resolved the destination client
458 information. This could cause of dropping one channel
459 message. Affected file lib/silcclient/client_channel.c.
461 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Added silc_client_run_one into lib/silcclient/silcapi.h and
464 lib/silcclient/client.c. This function is used when the SILC
465 Client is run under some other scheduler, or event loop or
466 main loop. On GUI applications, for example this may be
467 desired to used to run the client under the GUI application's
468 main loop. Typically the GUI application would register an
469 idle task that calls this function multiple times in a second
470 to quickly process the SILC specific data.
472 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
474 * Fixed silc_server_drop() for dropping the supplementary
475 groups as well, this could cause a security hole on some
478 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
480 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
483 * Write PID file after dropping privileges. Added -F option
484 to run server on foreground. A patch by debolaz.
485 Affected files silcd/server.c, silcd/silcd.c.
487 * Fixed MOTD to return the MOTD file server name. Affected
488 file silcd/command.c.
490 * Added INFO command reply handling to the Irssi SILC Client.
491 Affected file irssi/src/silc/core/client_ops.c.
493 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Fixed the silc_idcache_list_* routines to really support
496 the dynamic list. Fixes a crash. Affected file is
497 lib/silccore/silcidcache.c.
499 * Fixed the LIST command reply to really call LIST command's
500 pending callbacks. Affected file silcd/command_reply.c.
502 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
504 * Update conn->local_entry->nickname after giving NICK
505 command. Affected file lib/silcclient/command.c.
507 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
509 * Added the [pid] option to the silcd configuration file
511 Affected files: serverconfig.[ch] and silcd.c
513 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
515 * Save fingerprint in WHOIS command reply in server.
516 Affected file silcd/command_reply.c.
518 * Fixed NICK commands pending callback registration.
519 Affected file lib/silcclient/command.c.
521 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
523 * Use ++server->cmd_ident when sending commands in server,
524 instead of random number. Affected file silcd/command.c.
526 * Fixed GETKEY command reply to call actually GETKEY pending
527 command callbacks. Affected file silcd/command_reply.c.
529 * A bit stricter check for nicknames. Check for same nickname
530 in NICK command also. Affected file silcd/command.c.
532 * Do not call INFO command everytime client ID changes, only
533 during first connecting. Affected file lib/silcclient/client.c.
535 * Set the new nickname only after successful command reply for
536 NICK command is returned by server. Affected file
537 lib/silcclient/command.c.
539 * Remove nicknames from nicklist during server_signoff notify.
540 Should fix /NAMES bit more. The affected file is
541 irssi/src/silc/core/silc-channels.c.
543 * Added `fingerprint' field to the SilcIDListData in the
544 silcd/idlist.h to hold the fingerprint of the client's
547 Send the fingerprint of the client's public key in WHOIS
550 Affected files silcd/command.c, and silcd/idlist.[ch].
552 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
553 create fingerprint from given data.
555 * Show the fingerprint of the client's public key in WHOIS.
556 Affected files irssi/src/module-formats.[ch] and
557 irssi/src/silc/core/client_ops.c.
559 * Format the multiple same nicknames also during JOIN and
560 NICK_CHANGE notifys. Affected file is
561 lib/silcclient/client_notify.c.
563 * Do not print error on screen for invalid private message
564 payload since it can come if someone is sending private
565 messages with wrong key. Affected file
566 lib/silccore/silcprivate.c.
568 * Fixed multiple concurrent /PING crash. Affected file
569 lib/silcclient/command.c.
571 * Changed the wrong ID encoding. All IP addresses must be
572 in MSB first order in encoded format. They were encoded
573 wrong and was in LSB format. Affected files are
574 silcd/serverid.c, lib/silcutil/silcutil.c.
576 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
578 * Call the `connect' client operation through the scheduler
579 in case of error. Affected file lib/silcclient/client.c.
581 * Call the `failure' client operation even if the error
582 occurred locally during a protocol. Affected file is
583 lib/silcclient/protocol.c.
585 * Added support of sending LIST command to router from normal
586 server. This way normal server can get list of all channels
587 in the network too. Fixed the channel list sending in the
588 server too. Affected files are silcd/command.c, and
589 silcd/command_reply.[ch].
591 * Added silc_server_update_channels_by_server and
592 silc_server_remove_channels_by_server. They are used during
593 disconnection of primary router and in backup router protocol.
594 Affected file silcd/server_util.[ch], silcd/server.c and
595 silcd/server_backup.c.
597 * Fixed channel adding to global list in IDENTIFY command
598 reply in server. Affected file silcd/command_reply.c.
600 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
602 * If the incoming packet type is REKEY or REKEY_DONE process
603 that packet always synchronously. Fixes yet another MAC
604 failed error on slow (dialup) connections. Affected file
605 lib/silcclient/client.c and silcd/server.c.
607 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
609 * Call check_version SKE callback for initiator too. Affected
610 file lib/silcske/silcske.c.
612 * Implemented fix for security hole found in the SKE that was
613 fixed in the specification few days back; the initiator's
614 public key is now added to the HASH value computation.
615 Added backwards support for the old way of doing it too, for
616 old clients and old servers. Affected file is
617 lib/silcske/silcske.c.
619 * Enabled mutual authentication by default in SKE. If initiator
620 is not providing mutual authentication the responder will
621 force it. This will provide the proof of posession of the
622 private key for responder. The affected files are
623 lib/silcclient/protocol.c and silcd/protocol.c.
625 * Do not cache anymore the server's public key during SKE.
626 We do mutual authentication so the proof of posession of
627 private key is done, and if the server is authenticated in
628 conn auth protocol with public key we must have the public
629 key already. Affected file silcd/protocol.c.
631 * Added new global debug variable: silc_debug_hexdump. If
632 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
633 file lib/silcutil/silclog.[ch].
635 * Fixed compilation warning due to char * -> const char *.
636 Affected files lib/silcutil/silcnet.h, and
637 lib/silccore/silcauth.[ch].
639 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
641 * Fixed CMODE command when new channel key was created. If
642 the creation failed the old key was removed. Next time giving
643 same command would crash the server since the old key was
644 freed already. Affected file silcd/command.c.
646 * Fixed the silc_server_announce_get_channels to not crash
647 on reconnect. Affected file silcd/server.c.
649 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
651 * Added silc_log_set_debug_string function to set a regex
652 string to match for debug output. Only the function names,
653 or filenames matching the given debug string is actually
654 printed. This way it is possible to filter out those debug
655 strings that user is not interested in.
657 Fixed a bug in silc_string_regexify.
659 Affected files lib/silcutil/silclog.[ch], and
660 lib/silcutil/unix/silcunixutil.c.
662 * Changed the -d options in both server and Irssi SILC client
663 to take the debug string as argument. Affected files
664 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
666 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Added silc_hash_babbleprint to create a Bubble Babble
669 Encoded fingerprint. The encoding is developed by Antti
670 Huima (draft-huima-babble-01.txt), and it creates human
671 readable strings out of binary data. Affected file
672 lib/silccrypt/silchash.[ch].
674 * Print the babble print now in addition of fingerprint as well
675 in Irssi SILC client. Affected files are
676 irssi/src/fe-common/silc/module-formats.[ch],
677 irssi/src/fe-common/silc/core/client_ops.c.
679 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
681 * Fixed a security problem found in SKE. The initiator's
682 public key too is now added to the HASH hash value creation
683 which is signed by the responder to create the SIGN value.
684 This will prevent anyone in the middle to lie to the responder
685 about the initiator's public key. If this is done now, the
686 man in the middle will get caught. Updated the protocol
689 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
691 * Better installation directory handling. Configure module
692 paths and other paths automatically to example_silc* files
693 in doc/. A patch by toma.
695 * Fixed compiler warning from MPI library, and from SILC RNG.
698 * Added SILC_SERVER_PID_FILE to define the pid file for server.
699 It can be configured with ./configure. A patch by toma.
701 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
703 * Find correct make to use in prepare-clean. A patch by
704 toma. Affected file prepare-clean.
706 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
708 * Added irssi variables use_auto_addr, auto_bind_ip,
709 auto_bind_port and auto_public_ip.
711 * Changed the interface for silc_client_send_key_agreement
712 in lib/silcclient/silcapi.h
716 irssi/src/silc/core/silc-core.c
718 lib/silcclient/silcapi.h
719 irssi/src/silc/core/silc-channels.c
720 lib/silcclient/client_keyagr.c
723 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
725 * Added silc_pkcs_public_key_compare to compare two
726 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
728 * Check that the client who set the founder mode on the
729 channel is the same client that is giving the founder
730 mode to itself. It is done by comparing the saved public
731 key (it is saved even in the authentication is passphrase).
732 Affected file silcd/command.c.
734 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
736 * Do not process packet for disconnected socket connection.
737 Affected file lib/silccore/silcpacket.c.
739 * Process the DISCONNECT packet through scheduler in the
740 client library. Affected file lib/silcclient/client.c.
742 * Fixed the silc_client_packet_parse to not to increase
743 the packet sequence number if the conn->sock and the
744 current socket connection is not same. This can happen
745 for example during key agreement when the conn includes
746 multiple socket connections (listeners). Affected file
747 lib/silcclient/client.c.
749 * The sender of the file transfer request now provides also
750 the pointer (listener) for the key exchange protocol. If
751 the listener cannot be created then it sends empty key
752 agreement and lets the receiver provide the listener.
754 Added `local_ip' and `local_port' arguments to the
755 silc_client_file_send. If they are provided they are used,
756 if not then it will attempt to find local IP address, if
757 not found or bind fails then the remote client will provide
760 Affected files are lib/silcclient/client_ftp.c and
761 lib/silcclient/silcapi.h.
763 * Extended the FILE SEND command to support defining the
764 local IP and port for key exchange listener. They are
765 optional. Affected file irssi/src/silc/core/silc-servers.c.
767 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
769 * Defined to WHOIS command reply the sending of fingerprint
770 of the client's public key (if the proof of posession of the
771 corresponding private key is verified by the server).
772 Updated to the protocol specification.
774 * Added support of receiving the client's public key's
775 fingerprint in command reply in client library. Affected
776 file is lib/silcclient/command_reply.c, and
777 lib/silcclient/idlist.[ch].
779 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
781 * Do not send over 128 chars long nickname to the server
782 in NICK command. Affected file lib/silcclient/command.c.

785 in JOIN command. Affected file lib/silcclient/command.c.
787 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
789 * Assure that silc_server_close_connection cannot be called
790 twice for same socket context. Affected file is
793 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
795 * Send error message to application if opening file for
796 writing during file transfer fails. Affected file is
797 lib/silcclient/client_ftp.c.
799 Remove all file transfer sessions for a client that we're
800 removing from ID cache.
802 Affected file is lib/silcclient/client_ftp.c.
804 * Fixed silc_net_addr2bin to return correct address. Affected
805 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
807 * Fixed file transfer session removing on signoff notify.
808 Affected file irssi/src/silc/core/silc-servers.c.
810 * Added the SilcClientFileError to be returned in the monitor
811 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
812 Affected file lib/silcclient/silcapi.h.
814 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
816 * Fixed a crash in silc_client_ftp_free_sessions and
817 silc_client_ftp_session_free_client. Affected file
818 lib/silcclient/client_ftp.c.
820 * Added `disabled' field in the SilcChannelEntry in the server
821 to indicate if the server entry is disabled. Affected file
822 silcd/idlist.h, silcd/command[_reply].c.
824 * SILC server adds now /var/run/silcd.pid everytime it is
825 started. Affected file silcd/silcd.c.
827 * Added silc_server_packet_send_clients to send a packet to
828 the provided table of client entries. Affected file
829 silcd/packet_send.[ch].
831 * Fixed a crash in client resolving in client_prvmsg.c in
832 client library. Affected file lib/silcclient/client_prvmsg.c.
834 * Do not actually remove the client directly from ID cache
835 during SERVER_SIGNOFF, but invalidate it. This way we
836 preserve the WHOWAS info for the client. Affected file
839 * Fixed SERVER_SIGNOFF notify handling in the server. The
840 server is now able to process incoming SERVER_SIGNOFF notify
841 for a server that it doesn't even know about. It will remove
842 the clients provided in the notify. Affected file
843 silcd/packet_receive.c.
845 * Check for partial packet in data queue after every packet that
846 was found from the queue. Return and wait for more data if
847 there is partial data in queue. Affected file is
848 lib/silccore/silcpacket.c.
850 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
852 * Added SilcClietFileError enum to indicate error in
853 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
854 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
855 Affected files lib/silcclient/silcapi.h and

858 * Check that newsize in silc_buffer_realloc is larger than
859 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
861 * Added better monitor of file transfers. It now monitors
862 key agreement protocol during the file transfer too. Added
863 error reporting too. Affected files
864 irssi/src/silc/core/silc-servers.c,
865 irssi/src/fe-common/silc/module-formats.[ch].
867 * Wrote a help file for FILE command.
869 * Added silc_rng_global_get_byte_fast to get not-so-secure
870 random data as fast as possible. Random data is read from
871 /dev/urandom if available and from the SILC RNG if not
872 available. It is used in padding generation. Affected file
873 lib/silccrypt/silcrng.[ch].
875 * All packets in client library are now processed synchronously.
876 Optimized packet processing a lot. Affected file
877 lib/silcclient/client.c.
879 * All server connection packets are processing synchronously
880 now in server, to optimize packet processing. Affected file
883 * Include files are installed now only in Toolkit distribution
884 if make install is given. Affected files: all Makefile.am's.
886 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
888 * Assure that silc_client_notify_by_server_resolve does not
889 resolve the client information multiple times. If it cannot
890 be found by the first it cannot be found at all. Affected
891 file lib/silcclient/client_notify.c.
893 * Fixed WHOWAS command reply calling. Affected file
894 lib/silcclient/command_reply.c.
896 * Removed all references to silc_idlist_get_client from the
897 Irssi SILC client since that call is internal call used by
898 the library. The Irssi SILC client will use now client
899 retrieval functions found in silcapi.h.
901 * Fixed a bug in resolving nickname info before sending
902 private message. It used freed memory. Affected file
903 irssi/src/silc/core/silc-servers.c.
905 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Assure my_channels statistics cannot go negative in server.
908 Affected files silcd/server.c, silcd/server_util.c.
910 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

924 * Added silc_net_localip to return local host's IP address.
925 Affected file lib/silcutil/silcnet.[ch].
927 * If key exchange or rekey protocol is active for a connection
928 parse all packets syncronously since there might be packets
929 in packet queue that we are not able to process without first
930 processing packets before them. Affected file silcd/server,
931 lib/silcclient/client.c.
933 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
934 whether library should continue processing the packet.
935 Affected file lib/silccore/silcpacket.h.
937 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
938 SilcSFTPMonitorData to SFTP server to monitor various
939 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

966 lib/silcutil/silcutil.[ch].
968 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
970 * Resolve the client info when received private message or
971 channel message for a client which nickname we don't know.
972 Affected files lib/silcclient/client_prvmsg.c and
973 lib/silcclient/client_channel.c.
975 * Do not crash in /KEY if client is not connected. Affected
976 file irssi/src/silc/core/silc-channels.c.
978 * Added SilcClientStatus field to the SilcClientEntry in the
979 lib/silcclient/idlist.h.
981 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
982 is incomplete and is being resolved, it won't be resolved
985 Make sure also that USERS command reply does not resolve
986 twice information. Affected file is
987 lib/silcclient/command_reply.c.
989 Make sure that silc_client_get_clients_by_list does not
990 resolve twice same information.
992 * Check for valid client->id in the silc_server_free_client_data.
993 Affected file silcd/server.c.
995 * Fixed /GETKEY nick@server not to crash if the server entry
996 is not found. Affected file lib/silcclient/command.c.
998 * Fixed the silc_server_check_cmode_rights to check the
999 requested modes correctly. Affected file silcd/command.c.
1001 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Better checks for non-printable chars in nick added.
1004 Affected file silcd/command.c.
1006 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Call the silc_server_udpate_servers_by_server in the
1009 primary router that comes back online in the backup resuming
1010 protocol. Otherwise it routes packets wrong. Affected file
1011 silcd/server_util.[ch], silcd/server_backup.c.
1013 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1016 lib/silcutil/silcbuffmt.[ch].
1018 * Redefined the SILC packet header to include the padding
1019 length. Affected file lib/silccore/silcpacket.[ch].
1021 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1022 length for maximum padding up to 128 bytes). Affected
1023 file lib/silccore/silcpacket.h.
1025 * Removed all backwards support for old 0.5.x MAC thingies.
1026 The SILC packet header change makes it impossible to be
1027 backwards compatible.
1029 * Send the ENDING packet with timeout in the backup resuming
1030 protocol. This is to assure that all routers has connected
1031 to the primary router. Affected file silcd/server_backup.c.
1033 * Changed the RNG to take the first IV from random data. It
1034 used to take it from zero actually. Changed the RNG also
1035 to use /dev/urandom during session. /dev/random is used
1036 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1038 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Changed the SILC packet header to have the first two bytes
1041 (the packet length) encrypted. Affected files aroung the
1042 code tree, lib/silccore/silcpacket.[ch]. Removed the
1043 SilcPacketCheckDecrypt callback. It is not needed anymore
1044 since the silc_packet_receive_process will determine now
1045 whether the packet is normal or special.
1047 * Implemented the unidirectional MAC keys. Affected files
1048 lib/silcske/silcske.c, silcd/protocol.c and
1049 lib/silcclient/protocol.c.
1051 * Implemented the packet sequence number to the MAC computation.

1056 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Allow backup router to announce servers. All servers
1059 announced by backup router are added to the global list
1060 automatically. Update hte server's socket to our primary
1061 router also when backup router announces a server.
1062 Affected file silcd/packet_receive.c.
1064 * Do not update the client->router in the function
1065 silc_server_udpate_clients_by_server if the client is on
1066 global list. We might fail to find any specific server
1067 for locally connected clients and local cell clients. They
1068 should still use the `from' and not `to' as client->router.
1069 This fixes backup router resuming protocol. Affected file
1070 silcd/server_util.c.
1072 * Decrease channel statistics count only if the channel
1073 deletion worked. Affected files are silcd/server.c and
1074 silcd/server_util.c.
1076 * Added silc_server_update_servers_by_server to update origin
1077 of all server entries. Used during backup router protocol.
1078 Affected files silcd/server_util.[ch], silcd/server.c. and
1079 silcd/backup_router.c.
1081 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1082 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1083 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1084 lib/silccrypt/silchmac.c.
1086 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Assure that router cannot reroute the same channel message
1089 to the sender. Affected file silcd/packet_receive.c.
1091 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Made better checks that the channel message is not sent
1094 to the router it came from. Affected file is
1095 silcd/packet_send.c. Fixed memory leak too.
1097 * Announce informations for incoming router connection, but
1098 only after checking if it is replaced by backup router.
1099 Affected file silcd/packet_receive.c.
1101 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Fixed the backup resuming protocol to work in multiple
1104 router environment. Affected file silcd/server_backup.c.
1106 * Route packet only to one router in the function
1107 silc_server_packet_send_to_channel. Affected file is
1108 silcd/packet_send.c.
1110 * Fixed silc_server_send_notify_dest to set the broadcast
1111 flag. Fixed the silc_server_send_notify_topic to actually
1112 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1113 Affected file silcd/packet_send.c.
1115 * Changed the SFTP Filesystem interface. Changed the
1116 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1117 the filesystem operation function. The SilcSFTPFilesystem
1118 is now a context that is allocated by all filesystem allocation
1119 functions and it already includes the operations structure
1120 and filesystem specific context. It is given as argument
1121 now to the silc_sftp_server_start. This made the interface
1122 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1123 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1125 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Changed the backup router adding and getting interfaces
1128 in the server. The router that will be replaced by the
1129 specified backup router is now sent as argument. Affected
1130 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1133 * Added silc_net_addr2bin_ne to return the binary form of
1134 the IP address in network byte order. Affected files
1135 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1137 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1139 * Check for existing server ID in silc_server_new_server
1140 and in silc_server_connect_to_router_final and remove the
1141 old entry if it exists. Affected file silcd/packet_receive.c,
1144 * Send the channel message always to only one router, either
1145 in upstream or downstream. Affected file is
1146 silcd/packet_send.c.
1148 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1150 * Wrote the definition of the backup resuming protocol to the
1151 protocol specification.
1153 * Removed one redundant channel key generation from normal
1154 server during joining procedure. Removed one redundant
1155 channel key sending from server to router during joining
1156 procedure. Affected file silcd/command.c.
1158 * Made minor bugfixes to the backup router resuming protocol.
1159 Affected file silcd/server_backup.c, server.c.
1161 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1163 * Added --disable-asm configuration option. Affected files
1164 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1167 * Implemented the backup resuming protocol that is used to
1168 resume the primary router position in the cell after the
1169 primary router comes back online. Affected files
1170 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1171 and silcd/server_util.[ch].
1173 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Sleep two (2) seconds after sending QUIT command to server.
1176 Affected file lib/silcclient/command.c.
1178 * Assure that if outgoing data buffer is pending do not force
1179 send any data. Affected file silcd/packet_send.c.
1181 * Assure that if outgoing data buffer is pending do not force
1182 send any data. Affected file lib/silcclient/client.c.
1184 * Implemented the backup router support when the primary router
1185 goes down. The servers and routers can now use the backup
1186 router as new primary router without loosing connectivity.
1188 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1191 in the server to indicate disabled entry. All data read
1192 from the connection will be ignored and no data is sent
1193 for entry that is disabled. Affected files are
1194 silcd/idlist.h, silcd/server.c.
1196 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1198 * Created SFTP client and server test programs in the
1199 lib/silcsftp/tests directory.
1201 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Implemented memory filesystem (virtual filesystem) for
1204 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1207 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Implemented the SFTP (SSH File Transfer Protocol) to the
1210 lib/silcsftp. It includes SFTP client and SFTP server
1213 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Moved lib/silccore/silcprotocol.[ch] to the
1216 lib/silcutil library.
1218 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1219 take variable argument list pointer as argument. Affected
1220 file lib/silcutil/silcbuffmt.[ch].
1222 * Added silc_buffer_set function that is used to set data
1223 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1224 Affected file lib/silcutil/silcbuffer.h.
1226 * Changed various routines in the core library to use the new
1227 silc_buffer_set instead of allocating new buffer only for
1230 * Added 64-bit value formatting and unformatting support to the
1231 silc_buffer_[un]format routines. Affected file is
1232 lib/silcutil/silcbuffmt.[ch].
1234 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1235 to includes/bitmove.h.
1237 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1239 * Fixed channel user mode saving in client library. Affected
1240 file lib/silcclient/command[_reply].c.
1242 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Defined the file transfer to the SILC Protocol. Added
1245 new packet type SILC_PACKET_FTP and defined File Transfer
1246 Payload. The mandatory file transfer protocol is SFTP
1247 (SSH File Transfer Protocol). Affected file in addition
1248 of the internet draft is lib/silccore/silcpacket.h.
1250 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1251 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1252 is used as part of backup router protocol when the primary
1253 router of the cell is back online and wishes to resume
1254 the position as primary router.
1256 * Redefined the MAC generation keys in the protocol. The
1257 same key is not used anymore in both direction. Both
1258 direction will now use different keys for sending and
1259 receiving. This fixes a potential security flaw. This
1260 change causes incompatibilities in the protocol.
1262 * Redefined also the MAC computation from the packet.
1263 An packet sequence number is now added to the MAC
1264 computation. This prevents possible replay attacks against
1265 the protocol. This change too causes incompatibilities
1268 Added `sequence' field to the SilcPacketContext to hold
1269 the current sequence number for the packet.
1271 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Added `created' field to the SilcIDListData in the file
1274 silcd/idlist.h to indicate the time when the entry was
1277 * Added `created' field to the SilcChannelEntry too. Affected
1278 file silcd/idlist.h.
1280 * Added `creation_time' aguments to all the announcement functions
1281 in the server. If it is provided then only the entries that
1282 was created after the provided time frame are actually
1283 announced. Affected file silcd/server.[ch].
1285 * The protocol says that the Channel ID's IP address must be
1286 based on the router's IP address. Added check for this in
1287 the silc_server_new_channel when processing incoming New Channel
1288 Payload. Affected file silcd/packet_receive.c.
1290 * Print out the correct version with --version in SILC client.
1291 Affected file irssi/src/silc/core/silc-core.c.
1293 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Fixed WHOWAS command to check for completnes of the client
1296 entry always, not just when the command is coming from client.
1297 Affected file silcd/command.c.
1299 * Added new function silc_server_packet_queue_purge to purge the
1300 outgoing data queue to the network. After the function returns
1301 it is guaranteed that the outgoing packet queue is empty.
1302 Affected file silcd/packet_send.[ch].
1304 * Purge the outgoing packet queue in the rekey protocol's final
1305 callback to assure that all rekey packets go to the network
1306 before quitting the protocol. Affected file silcd/server.c.
1308 * Added silc_client_packet_queue_parse as similar function as
1309 in server to the client library. The affected file is
1310 lib/silcclient/client.c.
1312 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Splitted silcd/server.c and created silcd/server_util.[ch]
1315 for utility functions.
1317 * Added new socket flag SILC_SF_DISABLED to indicate that the
1318 connection is open but nothing can be sent to or received from
1319 the connection. Affected file lib/silcutil/silsockconn.[ch].
1320 The checking for disabled socket is checked in the low level
1321 silc_socket_write and silc_socket_read functions.
1323 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Allow only nicknames and channel names that fits into the
1326 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1328 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * When processing JOIN command reply in server check that if
1331 the channel exists in our global list we'll move it the local
1332 list. Affected file silcd/command_reply.c.
1334 * Fixed the check whether client is joined on the channel already
1335 in JOIN command. Affected file lib/silcclient/command.c.
1337 * Fixed the JOIN command reply to check whether the channel
1338 already exists. Affected file lib/silcclient/command_reply.c.
1340 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Added silc_ske_status_string to map the SKE error numbers
1343 to readable strings. The affected files are
1344 lib/silcske/silcske[_status].[ch].
1346 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Do not show the private channels on the WHOIS channel list
1349 as it is not allowed by the protocol. The affected file is
1352 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Assure that the packet length digged from the actual packet
1355 is something sensible in the silc_packet_decrypt_rest_special
1356 in lib/silccrypt/silcpacket.c.
1358 * Free and NULL the allocated pointer in silc_hmac_alloc if
1359 the HMAC allocation fails. The affected file is
1360 lib/silccrypt/silchmac.c.
1362 * Print the selected security properties to the log files in
1363 the server. Affected file silcd/protocol.c.
1365 * Add SKE's reference counter even if calling the completion
1366 callback manually. Otherwise it goes negative, although it
1367 does not cause any problems. The affected file is
1368 lib/silcske/silcske.c.
1370 * Remove the client entry with short timeout after giving the
1371 KILL command. Affected file lib/silcclient/command.c.
1373 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1374 case all found clients are already disconnected (WHOWAS would
1375 found them) in the server. Affected file silcd/command.c.
1377 * Update the last_receive (time of last data received) to be
1378 updated only when received private or channel message so that
1379 the idle time showed in WHOIS makes more sense.
1381 * Added boolean field `valid' in to the SilcClientEntry in the
1382 client library to indicate whether the entry is valid or not.
1383 This fixes the nickname change bug on channel when changing
1384 the nickname to be same than the old (like nick to Nick) the
1385 nickname formatter doesn't set the new nick anymore to Nick@host.
1386 Affected file lib/silcclient/idlist.[ch].
1388 * Now actually fixed the nickname changing on disconnection.
1389 Added new function silc_change_nick to the Irssi SILC Client.
1390 Affected file irssi/src/silc/core/client_ops.c,
1391 irssi/src/silc/core/silc-nicklist.[ch].
1393 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * Check that the public key exists in the GETKEY command before
1396 trying to encode it. Affected file silcd/command.c.
1398 * Print some notifications on received public keys with GETKEY
1399 command in the Irssi SILC Client. Affected files are
1400 irssi/src/fe-common/silc/module-formats.[ch],
1401 irssi/src/silc/core/client_ops.c.
1403 * Use IDENTIFY command to resolve the server information in the
1404 GETKEY command instead of INFO command. Affected file
1405 lib/silcclient/command.c.
1407 * All command reply functions in the client library now calls
1408 the pending command reply callbacks even if an error has
1409 occurred. The server has done this a long time and now it was
1410 time to move the client library to this as well. Now all
1411 errors can be delivered back to the pending command reply
1412 callbacks if necessary. Affected files are
1413 lib/silcclient/command[_reply].[ch].
1415 * Change the nickname on disconnection back to the username
1416 because in reconnect the server will enforce it to it anyway.
1417 Affected file irssi/src/silc/core/silc-servers.c.
1419 * Fixed a config file parsing bug in the Irssi SILC client.
1420 Affected file irssi/src/silc/core/clientconfig.c.
1422 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1424 * When printing the channel mode on JOIN, verify that the
1425 channel key and channel's HMAC are valid. Affected file
1426 irssi/src/silc/core/client_ops.c.
1428 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1431 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1432 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1434 * Removed channel key rekey task deleting from the function
1435 silc_server_save_channel_key. Affected file silcd/server.c.
1436 Added explicit timeout task context instead that is used to
1437 delete the task if we are registering a new task before the
1438 new task has elapsed.
1440 * When channel key rekey occurs the client library now saves
1441 the old channel key for a short period of time (10 seconds) and
1442 is able to use it in case some is still sending channel
1443 messages encrypted with the old key after the rekey. Affected
1444 file lib/silcclient/[idlist.h|client_channel.c].
1446 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Added check to the silc_server_new_id_real to not accept
1449 new ID if it is the sender's own ID. Affected file is
1450 silcd/packet_receive.c.
1452 * Assure that we do not announce ourself or the one we've
1453 sending our announcements when we're router and are announcing
1454 servers to our primary router. Affected file silcd/server.c.
1456 * Fixed silc_server_command_identify_check_client to assemble
1457 correct WHOIS packet. It send corrupted WHOIS packet and
1458 caused problem with router to router connections. Affected
1459 file silcd/command.c.
1461 Fixed also silc_server_command_whois_check the same way
1462 as for the IDENTIFY command.
1464 * Added new SilcIDListStatus to the server in the SilcIDListData
1465 structure. The status now includes the current status of
1466 the entry (like registered, resolved etc.). Affected file
1467 silcd/idlist.[ch]. Defined a bunch of different status types
1468 as well. This replaced the old boolean registered field as well.
1470 Added resolve_cmd_ident field to the SilcClientEntry structure
1471 too so that if the entry is for example being resolved so
1472 another command may attach to the same pending command reply
1473 without requiring to resolve the same entry again. This concept
1474 should optimize the WHOIS and the IDENTIFY resolving under
1475 heavy load by taking away unnecessary resolving for entries
1476 that are being resolved already.
1478 Added support for adding multiple pending commands for one
1479 command idenfier. Affected file silcd/command[_reply].[ch].
1481 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1482 before deleting the data. Otherwise the hash table will have
1483 freed data in comparison functions. Affected file is
1484 silcd/command_reply.c.
1486 * Fixed silc_idlist_replace_client_id to add the new entry to
1487 the cache with NULL nickname. Otherwise there will be invalid
1488 memory as the nickname after the nickname is freed. Affected
1489 file silcd/packet_receive.c.
1491 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1492 saved into wrong slots because the previous number of entries
1493 was not taken into account. Affected file silcd/idlist.c.
1494 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1496 * If we are router and we receive JOIN notify to a channel that
1497 does not have any users then notified client is marked as the
1498 channel founder, as it is it. The affected file is
1499 silcd/packet_receive.c
1501 * Added to the extended hash table API's table_del_*ext functions
1502 the destructor as argument too, so that the caller can decide
1503 which destructor to use or whether to use destructor at all.
1504 Affected file lib/silcutil/silchashtable.[ch].
1506 * Fixed ID Cache purging. It actually deleted the entries from
1507 the hash table after the data was freed. The hash table ended
1508 up comparing freed memory. The affected file is
1509 lib/silccore/silcidcache.c.
1511 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Fixed Irssi SILC client's KILL command's HELP syntax.
1515 * The USERS command now resolves the detailed user information
1516 if the userinfo field is missing. Affected file is
1517 lib/silcclient/command_reply.c.
1519 * Do not print error in silc_file_read if the read file does
1520 not exist. Just silently return NULL. Affected file is
1521 lib/silcutil/silcutil.c.
1523 * Fixed the silc_log_output to not wine about NULL filename
1524 and to not create some bogus " " filename. Affected file is
1525 lib/silcutil/silclog.c.
1527 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1529 * Fixed various printing bugs on the user interface in the
1530 Irssi SILC Client. Minor changes that were forgotten from
1533 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1535 * Fixed the configure.in.pre and the compilation and distribution
1536 environment to support the new autoconf 2.52. That version is
1537 now required to compile the CVS trunk.
1539 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1542 to generally parse user@fqdn format strings. Affected file
1543 lib/silcutil/silcutil.c.
1545 * Added nickname_format and nickname_force_format fields to the
1546 SilcClientParams structure. The first one defines the format
1547 for the nicknames that the library will enforce if the receives
1548 multiple same nicknames. The second one is boolean value and
1549 can be used to force the library to always enforce the format
1550 to the nicknames regardles whether there are multiple nicknames
1551 or not. This configurable formatting was employed to flexibly
1552 support accessing multiple nicknames from the user interface.
1553 The userinterface can now set the nicknames to what ever format
1554 they prefer. Affected file lib/silcclient/silcapi.h.
1556 Added function silc_client_nickname_format to the file
1557 lib/silcclient/idlist.c. It performs the nickname formatting.
1559 Added new field `hostname´ to the SilcClientEntry context.
1560 It holds the hostname of the client. Affected file is
1561 lib/silcclient/idlist.h.
1563 * Irssi SILC Client sets the nicknames in nick@hostn format.
1564 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1565 irssi/src/silc/core/silc-core.c.
1567 The WHOIS printing now also shows both the real nickname and
1568 the formatted nickname so that user knows how to access the
1569 user if there are multiple same nicknames cached. Affected
1570 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1571 printing formatting too to take the hostname now as a separate
1572 argument. The Affected file is
1573 irssi/src/fe-common/silc/modules-formats.[ch].
1575 * Changed the silc_client_get_clients_local to accept the formatted
1576 nickname as argument. It accepts the real nickname too but the
1577 formatted nickname can be used to find the true entry from
1578 multiple entries. Affected file lib/silcclient/silcapi.h and
1579 lib/silcclient/idlist.c.
1581 * Added nickname_format_parse field to the SilcClientParams.
1582 It is a callback function provided by the application to parse
1583 the nickname out of the formatted nickname string. The library
1584 calls it to get the nickname from the formatted string. Since
1585 the application generally knows better the format of the nickname
1586 string it parses it instead of the library, even though library
1587 encodes the formatted string. If the callback function is not
1588 provided then the library will use the string as is. The
1589 affected file is lib/silcclient/silcapi.h.
1591 * All the nickname strings passed to the client library in
1592 commands are now expected to be formatted nickname strings.
1593 If the command does not support the formatted nickname string
1594 it will assume that the sent string is the actual nickname.
1595 Affected file lib/silcclient/command.c.
1597 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * Added public key authentication support to OPER and SILCOPER
1600 commands in the client library. Affected file is
1601 lib/silcclient/command.c.
1603 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * Changed the get_auth_methdod client operation to be asynchronous.
1606 It can be async if the application resolves the authentication
1607 method from the server during the negotiation. Added new
1608 SilcGetAuthMeth completion callback that the application will
1609 call after resolving the authentication method.
1611 Added function silc_client_request_authentication_method that
1612 the application can use to resolve the authentication method
1613 from the server. Added also SilcConnectionAuthRequest callback
1614 that the library will call after the server has replied. The
1615 application can call this function if it does not know the
1616 current authentication method.
1618 Affected files are lib/silcclient/client.c and
1619 lib/silcclient/silcapi.h.
1621 * The Irssi SILC client now automatically resolves the authentication
1622 method incase any configuration information is not present (and
1623 currently there never is). The affected file is
1624 irssi/src/silc/core/client_ops.c.
1626 * Fixed public key authentication from the client library.
1627 Affected file lib/silcclient/protocol.c. Changed also the
1628 protocol specification about the public key authentication in
1629 the connection authentication protocol. The actual data to be
1630 signed is now computed with a hash function before signing.
1632 * Fixed the public key authentication from the server as well.
1633 Affected file silcd/protocol.c.
1635 * Removed the mlock()'s from the memory allocation routines.
1636 Affected file lib/silcutil/silcmemory.c. The ./configure does
1637 not check anymore for the mlock(). Affected file is
1640 * Fixed USERS command in server to allow the execution of the
1641 command for private and secret channels if the client sending
1642 the command is on the channel. Affected file silcd/command.c.
1644 * Fixed silc_client_get_clients_local to return the clients
1645 count correctly. It could return wrong value. Affected file
1646 lib/silcclient/idlist.c.
1648 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1651 types. The assembler optimizations seemed not to like 64-bit
1652 data types. The assmebler optimizations thus are now enabled
1653 also for BSD systems as opposed to only enable them for Linux.
1655 * Do not check for threads at all on BSD systems. Affected
1656 file configure.in.pre.
1658 * Removed -n and -h options from the Irssi SILC Client since
1659 they are not used in silc.
1661 * Fixed the prime generation to assure that the first digit
1662 of the generated random number is not zero since our conversion
1663 routines does not like number strings that starts with zero
1664 digit. If zero digit is seen the random number is regenerated.
1665 This caused some corrupted RSA keys when the zero first digit
1666 was met. Affected file lib/silcmath/silcprimegen.c.
1668 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Fixed WIN32 configuration in the ./configure script.
1671 Fixed to include xti.h on environments that has it.
1672 Patches by Carsten Ilchmann and andrew.
1674 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Changed the silc_id_create_client_id to be collision
1677 resistant. It is now assured that there cannot be created
1678 two same client ID's. I suspect that some weird bugs in
1679 the server were actually caused by duplicate Client IDs.
1680 Affected file silcd/serverid.[ch]. A router receiving
1681 new ID now also assures and informs the sending server
1682 if the ID caused collision.
1684 * Changed the silc_id_create_channel_id to also assure that
1685 there are no collisions.
1687 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Statement about ignoring the Mutual Authentication flag when
1690 performing rekey with PFS was a bit misleading. It is ignored
1691 if it was set in the initial negotiation, it cannot be even
1692 set in the rekey. Fixed in the ke-auth draft. Started the
1693 new versions of the protocol drafts in the doc/.
1695 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Fixed a bug in silc_client_command_identify_save when saving
1698 new channel information. The channel name was no duplicated
1699 and caused crash on exit. Affected file is
1700 lib/silcclient/command_reply.c.
1702 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Fixed the getkey command handling in the server. Send just
1705 empty OK reply to the sender if the key could not be fetched
1706 (but everything else was ok, like the key just was not available).
1707 Changed the public key parameter to optional in the protocol
1708 specs so that empty OK reply can be sent. Affected file
1711 Added a message to Irssi SILC client to tell to user if the
1712 server did not return a public key.
1714 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Fixed a channel key regeneration bug. It registered new
1717 timeout tasks exponentially until all system resources were
1718 used. Affected file silcd/server.c.
1720 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Added the SILC Document generator to the scripts/silcdoc.
1723 It can be used to generate the Toolkit Reference Manual out
1724 of the source tree. Internally it will also use the RoboDoc
1725 generator now imported in util/robodoc.
1727 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Added couple of return's in rekey protocol if error orccurred
1730 during the protocol. The execution must be terminated.
1731 Affected file silcd/protocol.c. Also, terminate the protocol
1732 always with timeout.
1734 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * The client's Client ID was created initally from the wrong
1737 nickname (it could have been in format nick@host) in the
1738 silc_server_new_client. Affected file silcd/packet_receive.c
1740 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Added some SILC_LOG_ERROR's to various error conditions
1743 if client could not be added to ID cache. Affected files
1744 silcd/packet_receive.c and silcd/server.c.
1746 * When client's sock->user_data is freed, NULL also the
1747 client->router and client->connection pointers. Added check
1748 for these pointers being NULL to various places around the
1749 code. Affected file silcd/server.c.
1751 * Added client->data.registered == TRUE checks to various
1752 places around the code to assure that unregistered client's
1753 are not handled when it is not allowed. Affected file
1756 * Added `bool registered' fields to all
1757 silc_idlist_[server|client]_get_* routines to indicate whether
1758 the fetched client needs to be registered or not. Affected
1759 file silcd/idlist.[ch].
1761 * Add your own entry as registered to the ID cache in the
1762 server. Affected file server.c.
1764 * Fixed a bug in silc_server_new_server. The SilcServer was
1765 set as the new server's context instead of SilcServerEntry.
1766 This naturally caused some weird bugs.
1768 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Do not delete the channel rekey task when adding it
1771 for in silc_server_create_channel_key.
1773 * Changed the silc_server_create_channel_key to return
1774 TRUE or FALSE to indicate the success of the channel key
1777 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1779 * Fixed MSVC++ project files and added missing files to
1780 Makefiles under win32/.
1782 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Do not add TCP_NODELAY flag if the operating system
1785 does not have it defined. Affected files are
1786 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1788 * Fixed buffer overflow from Irssi SILC Client. Affected
1789 file irssi/src/fe-common/core/themes.c.
1791 * Fixed double free in client library in the file
1792 lib/silcclient/client.c when disconnecting from server.
1794 * Applied double free patch from cras to Irssi SILC client.
1795 Affected files irssi/src/core/[modules/expandos].c
1797 * Fixed the disconnection handling to Irssi SILC Client.
1798 The application must call silc_client_close_connection
1799 in ops->connect client operation in case of failure of
1800 the connection. Affected file is
1801 irssi/src/silc/core/client_ops.c.
1803 * Do not set sock->protocol to NULL in the function
1804 silc_client_close_connection after executing the protocol's
1805 final callback since the sock might not be valid anymore.
1806 Affected file lib/silcclient/client.c.
1808 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Do not enable SILC_THREADS if the linking with libpthread
1811 did not happen. Affected file configure.in.pre.
1813 * Added notion to protocol specification that server must
1814 verify the sent authentication payload with CMODE when
1815 setting the channel founder key. Implemented it to the
1816 server. Affected file silcd/command.c.
1818 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Added _EXTRA_DIST SILC distribution variable to the
1821 distributions file. It is used to conditionally add extra
1822 files or directories to the specific distribution. Affected
1823 files ./prepare, Makefile.am.pre and distributions.
1825 Removed the `_' from the start of the distribution names.
1828 * Added README.WIN32 for instructions to compile the Toolkit
1831 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Fixed a double free in disconnection in the server. Affected
1834 file is silcd/server.c.
1836 * Fixed the lib/silcske/groups.c to work now also with GMP
1837 MP library. The string conversion did not work when using
1838 specific base and the base is indicated in the string as well.
1840 * Created win32/ directory which now includes MSVC++ specific
1841 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1842 It will appear only in the toolkit distribution
1844 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Changed the key material distribution function in case when
1847 the hash output is too short. The data is now concatenated
1848 a bit differently than it used to. Made the change to the
1849 SKE protocol specification.
1851 * Added better GMP detection to configure.in.pre. A patch
1854 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed a minor bug in SKE that might cause some problem on
1857 some platforms. Affected file lib/silcske/silcske.c.
1859 * Added the cookie checking for initiator in the SKE. It checks
1860 that the responder returns the sent cookie unmodified. The
1861 affected file is lib/silcske/silcske.c. Added new SKE
1862 error type INVALID_COOKIE that can be sent during the
1863 negotiation. Fixed some memory leaks as well.
1865 * Added the "invalid cookie" error message to Irssi SILC client's
1868 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * Added `task_max' field to the SilcClientParams to indicate
1871 the maximum tasks the scheduler can handle. If set to zero,
1872 default values are used. Affected file lib/silcclient/silcapi.h.
1874 * Fixed memory leaks in silc_client_close_connection. Affected
1875 file lib/silcclient/client.c.
1877 * Added silc_client_del_client_entry to client library to free
1878 all memory of given client entry. Affected file is
1879 lib/silcclient/idlist.[ch].
1881 * Added new functions silc_client_del_channel and
1882 silc_client_del_server to delete channel and server entries.
1883 Affected file lib/silcclient/[silcapi.h/idlist.c].
1885 * Removed silc_client_del_client_by_id from silcapi.h.
1887 * Fixed the INFO command to return the server's own info
1888 correctly when querying by Server ID. Affected file is
1891 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Removed the non-blocking settings in WIN32 code in the
1894 silc_sock_[read/write] and added SleepEx instead. Affected
1895 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1896 of input data is now checked with FIONREAD and ioctlsocket.
1898 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Call silc_schedule_task_del_by_context in the
1901 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1902 Affected file lib/silccore/silcprotocol.c.
1904 * Call silc_protocol_cancel for active protocols in the
1905 silc_server_close_connection if the funtion
1906 silc_server_free_sock_user_data has not been called.
1907 Affected file silcd/server.c.
1909 * Generic tasks cannot be deleted using the del_by_fd
1910 task deleting function since generic tasks does not match
1911 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1913 * Added a notion to SILCOPER help file that the SILCOPER works
1914 only on router server, not on normal server.
1916 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Added for WIN32 support for the new scheduler as well.
1919 Affected file lib/silcutil/win32/silcwin32schedule.c.
1921 * Fixed the SHA1 implementation to work on various platforms.
1923 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1926 API. It is part of the scheduler now. Everything else is
1927 as previously but some functions has changed their names.
1928 Checkout the lib/silcutil/silcschedule.h for the interface.
1929 Updated all applications to use the new interface. Affected
1930 files are lib/silcutil/silcschedule.[ch].
1932 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Found a bug in the SKE implementation. The HASH value,
1935 specified by the protocol, was not computed correctly. The
1936 public key of the responder was not added to the computation
1937 even though it is mandatory. Affected file lib/silcske/silcske.c.
1938 This unfortunately causes incompatibilities with older
1939 clients and servers.
1941 * Added WIN32 specific network init and uninit functions:
1942 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1943 the Winsock2. Affected file lib/silcutil/silcnet.h and
1944 lib/silcutil/win32/silcwin32net.c.
1946 * Set the socket always to nonblocking mode on WIN32 after
1947 reading data or writing data. Affected file is
1948 lib/silcutil/win32/silcwin32sockconn.c.
1950 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * Fixed various compilation problems under WIN32. Affected
1953 files lib/silcutil/win32/silcwin32thread.c and
1954 lib/silcutil/win32/silcwin32schedule.c.
1956 * Removed all _internal.h #includes from public header
1957 files. Internal headers must never be included from
1960 Removed also the lib/silcske/payload_internal.h file.
1962 * All include files that may be needed (public and some others
1963 included by the public headers) by application developers are
1964 now copied to the ./includes directory. It does not copy any
1965 internal headers. Affected file Makefile.defines.pre and all
1966 Makefile.am's under lib/ and subdirs.
1968 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Do not change the ~/.silc directory's permissions automatically.
1971 Affected file irssi/src/silc/core/clientutil.c.
1973 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Do not cancel the protocol in silc_server_close_connection
1976 it might cause recursion. Now cancelled in the function
1977 silc_server_free_sock_user_data. Affected file silcd/server.c.
1979 * Fixed the silc_server_remove_clients_by_server to regenerate
1980 the channel keys correctly finally. Added also new function
1981 silc_server_remove_clients_channels to actually do it.
1982 Affected file silcd/server.c.
1984 * Fixed the silc_server_new_channel to not crash by giving
1985 wrong router to the new channel. Affected file is
1986 silcd/packet_receive.c.
1988 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1991 which is given as argument to the silc_client_alloc now.
1992 It can be used to configure the client and set various parameters
1993 that affect the function of the client.
1995 * The USERS command in server did not check whether the channel
1996 is private or secret. Affected file silcd/command.c.
1998 * Added new argument to the USERS command in protocol specification.
1999 The USERS command now can take the channel name as argument
2000 as well. Added support for this in client and server and
2001 updated the protocol specs.
2003 * Completed the GETKEY command in client. It can be now used
2004 to fetch also servers public key not only some clients.
2005 Affected files lib/silcclient/command[_reply].c.
2007 * Added silc_client_get_server to return server entry by the
2008 server name. Affected files lib/silcclient/silcapi.h and
2011 * Redefined the IDENTIFY command in protocol specification to be
2012 more generic. It now can be used to query information about
2013 any entity in the SILC Network, including clients, servers and
2014 channels. The query may be based either the entity's name
2015 or the ID. Added support for this in both client and server.
2017 Affected files silcd/command.c and lib/silcclient/command.c
2018 and command_reply.c.
2020 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2021 the _from_client and _from_server functions. Affected file
2024 * Added silc_client_get_channel_by_id_resolve to the file
2025 lib/silcclient/silcapi.h to resolve channel information by
2026 its ID. Added also silc_client_get_channel_by_id that
2027 does not resolve it from the server.
2029 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Added SilcServerEntry context into the client library
2032 to represent one server. The INFO command now allocates
2033 these to save the resolved server info. For now on the
2034 client library will also keep information about servers,
2035 connected and resolved with INFO.
2037 The INFO command now allocates the SilcServerEntry context
2038 and saves the server info there. The COMMAND_REPLY in
2039 the INFO now returns the parameters to application in
2040 same order as defined in the protocol specification.
2042 The entries are cached in the client->server_cache.
2044 * The INFO command is now issued after received the Client ID
2045 from the server. Affected file lib/silcclient/client.c.
2047 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2048 to the application as the mode changer might be server.
2049 It is guaranteed that NULL is not returned anymore to the
2050 application. Affected file lib/silcclient/client_notify.c.
2052 The ID Type is now also passed to the application so that
2053 it can check whether the returned entry is SilcClientEntry
2056 Added new function silc_client_get_server_by_id to return
2057 the server entry by ID. Affected files are the
2058 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2060 * Do not create the channel in the Irssi SILC Client when issuing
2061 the JOIN command but when received the sucessful JOIN command
2062 reply. Otherwise the channel might get created even though we
2063 could not join it. The Affected file is
2064 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2066 * Fixed a channel joining bug in router. The router must also
2067 check the channel modes, invite and ban lists etc. when serving
2068 the JOIN command sent by normal server. Affected file is
2069 silcd/command.c. The router now resolves the client's
2070 information from the server who sent the JOIN command if it
2071 does not know it, and processes the JOIN command only after
2074 * Changed the SilcCommandCb to take new argument; void *context2.
2075 Affected file lib/silccore/silccommand.h
2077 The second argument in the command callbacks in the server now
2078 includes the SilcServerCommandReplyContext if the command was
2079 called as pending command callback from the command reply.
2080 Otherwise it is NULL. When called as pending the status of the
2081 command reply will be checked and if it was erronous the
2082 error will be sent to the original sender of the command.
2083 This way the client always receives the error messages even
2084 though the server was actually the one who received the error
2085 when it resent the command to router, for example. Affected
2086 files silcd/command[_reply].[ch].
2088 * Fixed sending WHOWAS command's error message to client if
2089 the requested client could not be found. It was missing.
2092 * Changed the CMODE and CUMODE commands reply arguments in the
2093 protocol specification. The Channel ID is now sent in both
2094 of the commands to identify the channel. Implemented this
2095 new feature to the client and server. Affected files
2096 lib/silcclient/command_reply.c and silcd/command.c.
2098 * Made better checks for invite and ban lists in the JOIN
2099 command in server. Affected file silcd/command.c.
2101 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * The server now performs the incoming host IP/DNS lookup
2104 using the silc_socket_host_lookup and thus does not block
2105 the server anymore. Affected file silcd/server.c.
2107 * Completed the multi-thread support for SILC Scheduler in
2108 the lib/silcutil/silcschedule.c.
2110 * Fixed the configure.in.pre to detect the pthread correctly
2113 * Fixed a deadlock in silc_task_queue_wakeup in the file
2114 lib/silcutil/silctask.c.
2116 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * Added new function silc_schedule_wakeup that is used in
2119 multi-threaded environment to wakeup the main thread's
2120 schduler. It needs to be used when a thread adds a new task
2121 or removes a task from task queues. After waking up, the
2122 scheduler will detect the task queue changes. If threads
2123 support is not compiled in this function has no effect.
2124 Implemented the wakeup mechanism to both Unix and WIN32
2125 systems. Affected files are lib/silcutil/silcschedule.[ch],
2126 lib/silcutil/unix/silcunixschedule.c and the
2127 lib/silcutil/win32/silcwin32schedule.c.
2129 * Added new function silc_task_queue_wakeup to wakeup the
2130 scheduler by the specified task queue. Affected file
2131 lib/silcutil/silctask.[ch].
2133 * The silc_socket_host_lookup_start now wakes up the scheduler
2134 after adding the timeout task. Affected file is
2135 lib/silcutil/silcsockconn.c.
2137 * The silc_socket_host_lookup is synchronous now if the threads
2138 support is not compiled in. However, the callback is still
2139 called asyncronously through the scheduler, anyway. Affected
2140 file lib/silcutil/silcsockconn.c.
2142 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Added new function silc_socket_host_lookup to perform
2145 asynchronous IP and FQDN lookups for the socket connection.
2146 Affected files lib/silcutil/silcsockconn.[ch].
2148 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2151 that may or may not compile the mutex support in.
2153 Changed the silc_mutex_alloc interface. It allocates the
2154 mutex now to the sent pointer and returns TRUE or FALSE.
2156 Affected file lib/silcutil/silcmutex.h.
2158 * Wrote the SILC Task Queue interface to support multi-threads.
2159 Affected file lib/silcutil/silctask.[ch].
2161 * Wrote the SILC Scheduler to support multi-threads. Affected
2162 file lib/silcutil/silcschedule.c.
2164 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2167 in lib/silcutil/win32/.
2169 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Defined SILC Mutex API and SILC Thread API and implemented
2172 them for Unix. Affected files are
2173 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2174 lib/silcutil/unix/silcunixmutex.c and
2175 lib/silcutil/unix/silcunixthread.c.
2177 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Fixed the silc_server_remove_clients_by_server's channel
2180 key re-generation. The hash table handling was incorrect
2181 and would not work with many channels. Affected file is
2184 * Fixed some memory leaks around the server code.
2186 * Rewrote the silc_server_get_users_on_channel to support IPv6
2187 based Client ID's. Affected file silcd/server.c.
2189 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2190 specification. However, a separate document must be written
2191 to define the detailed signing procedure and the payload
2192 associated with the flag. Defined the flag to the
2193 lib/silccore/silcchannel.h as well.
2195 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * Changed the dynamic tables to static size tables in the
2198 lib/silccrypt/silchmac.c.
2200 * Removed GCC dependencies from the code. A patch by cras.
2202 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Do not show the error "Error receiving packet bla bla"
2205 in server if it really was not an error (-2 means that reading
2206 is pending). Affected file silcd/server.c.
2208 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Fixed a possible crash in silc_server_remove_clients_by_server
2211 in silcd/server.c. Fixed there also some memory leaks.
2213 * Fixed the silc_idlist_replace_client_id. It could replace
2214 wrong key in the hash table. Affected file silcd/idlist.c.
2216 * Do not check whether there are global users on the channel
2217 if the channel->global_users is FALSE. Affected functions
2218 silc_server_remove_from_one_channel and
2219 silc_server_remove_from_channels in silcd/server.c. Also,
2220 do not check if the removed client is local as we can be
2221 sure that global client was not removed from the channel
2222 and checking for global users is not needed.
2224 * The silc_server_remove_clients_by_server now re-generates
2225 the channel keys correctly for those channels that had
2226 clients removed from them. Affected file silcd/server.c.
2228 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Found the reason of random crashes in the server. We weren't
2231 ignoring the SIGPIPE signal (which can be sent in write())
2232 and it crashed the server. Affected file silcd/silcd.c.
2234 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Assure that sock->user_data is not NULL in the function
2237 silc_server_packet_send in silcd/packet_send.c.
2239 * Disconnect the remote connection if it could not be added
2240 to any ID lists in the server. The affected file is
2243 * Check in silc_server_packet_send[_real/dest] that the
2244 socket is not disconnecting and ignore the data if it is.
2245 Affected file silcd/packet_send.c.
2247 * Define inline to __inline on native WIN32 compilation.
2248 Affected file includes/silcwin32.h.
2250 * Added some explicit type casts for inline code since MSVC
2251 require them. Affected files lib/silcutil/silcbuffer.h,
2252 lib/trq/silcdlist.h and lib/trq/silclist.h.
2254 * Print warning in log files from now on if the packet
2255 decryption fails. Affected file silcd/server.c.
2257 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Changed the `say' client operation's interface to accept
2260 new `type' argument to indicate the type of the message sent
2261 by the library. The application may filter the library's
2262 messages according the type. The affected file is the
2263 lib/silcclient/silcapi.h.
2265 * Added two new functions to lib/silcclient/silcapi.h:
2266 silc_client_del_client and silc_client_del_client_by_id.
2267 Affected file lib/silcclient/idlist.c.
2269 * Moved the clientincludes.h from includes/ to silc/ and
2270 serverincludes.h from includes/ to silcd/.
2272 * The modes for the CMODE and CUMODE are now passed as
2273 uint32 for application with COMMAND_REPLY. The affected
2274 file is lib/silcclient/command_reply.c.
2276 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * /WHOIS without arguments shows client's own information.
2279 Affected file lib/silcclient/command.c.
2281 * Changed PING to not accept any arguments. The specs
2282 says that client can ping only the connected server so
2283 requiring an argument is not needed. Affected file is
2284 lib/silcclient/command.c.
2286 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Fixed a fatal bug in private message sending and reception
2289 encryption and decryption when using private message keys.
2290 The implementation was incorrect and did not follow the
2291 specification. It causd that some of the message were
2292 lost since it did not use the sending and receiving keys
2293 as the protocol suggests. This has been fixed and will cause
2294 incompatibilities with older clients when sending private
2295 message encrypted with private message keys. Affected files
2296 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2297 and various other in Irssi SILC Client.
2299 Added `responder' boolean argument to the functions
2300 silc_client_add_private_message_key[_ske] to indicate when
2301 the key is added as responder or initiator of the key
2304 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Removed the silc_ske_check_version function and created
2307 a SilcSKECheckVersion callback. Added also a function
2308 silc_ske_set_callbacks that is now used to set all SKE
2309 callbacks. The callback functions are not given to
2310 the SKE functions anymore, but this function is used to
2313 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2315 * Added `silc_version' argument to the silc_client_alloc
2316 to define the version of the application for the library.
2317 The library will use the version string to compare it
2318 against the remote host's (usually a server) version
2319 string. Affected file lib/silcclient/silcapi.h
2321 * Added the KE protocol context to Key Agreement context
2322 in client library so that we can abort the SKE if it
2323 is in process when we get timeout. Affected file is
2324 lib/silcclient/client_keyagr.c.
2326 * Do not resolve the client ID forever if it returns in the
2327 first time that such client does not exist. This was done
2328 for example with private message. Affected file is
2329 lib/silcclient/client_prvmsg.c.
2331 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Do not add regex.h for WIN32. The affected file
2334 includes/silcincludes.h.
2336 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2337 not work yet 100%. It generates the DLL's automatically
2338 when compiling with --with-win32 under cygwin.
2340 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * lib/contrib/regex.c is not compiled on WIN32.
2344 * Added silc_net_get_socket_opt function to the
2345 lib/silcutil/silcnet.h.
2347 * Added includes/silcwin32.h for WIN32 specific includes
2350 * Do not use ptime structure or any of the posix process
2351 functions on WIN32 in lib/silccrypt/silrng.c.
2353 * Added silc_gettimeofday to provide generic function
2354 for struct timeval on all platforms. Added the function
2355 to lib/silcutil/silcutil.h.
2357 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2360 library as they clearly belong there. As a plus side we
2361 can make the actual socket connection routines platform
2364 Added also new generic function silc_socket_read and
2365 silc_socket_write (that used to be silc_packet_[read/write].
2366 The implementation of these are platform specific.
2368 * Added WIN32 specific routines of silc_socket_[read/write]
2369 to lib/silcutil/win32/silcwin32sockconn.c.
2371 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Added preliminary support for native WIN32 compilation under
2374 cygwin (using the -mno-cygwin option for GCC) to the
2375 ./configure.in.pre. The --with-win32 now prepares the
2376 compilation for native WIN32.
2378 * Rewrote the SILC Scheduler interface in the file
2379 lib/silcutil/silcschedule.h. The scheduler is now context
2380 based and does not have anymore any global static scheduler.
2381 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2382 and created lib/silcutil/win32 directory for WIN32 based
2385 * Added Unix specific network routines to the
2386 lib/silcutil/unix/silcunixnet.c and the old
2387 lib/silcutil/silcnet.c includes now only generic routines.
2389 Added WIN32 specific network routines to the
2390 lib/silcutil/win32/silcwin32net.c.
2392 * Added Unix specific utility functions from the
2393 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2395 * Added WIN32 SILC Scheduler to the file
2396 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2399 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Do not handle JOIN notify in the server if the target client
2402 is not registered (idata->registered == FALSE). The affected
2403 file is silcd/packet_receive.c.
2405 * Update the nickrec->founder in event_cumode in the Irssi SILC
2406 client. Affected file irssi/src/silc/core/silc-channels.c.
2408 * Fixed the CUMODE_CHANGE notify handling in the server when
2409 server and router are announcing their clients on channels.
2410 Now the mode changes are saved and notified correctly. The
2411 affected file is /silcd/packet_receive.c.
2413 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2414 They really did not replace the cache entry in the ID Cache.
2415 Now they do that. Affected file silcd/idlist.c.
2417 * Fixed the KICK notify handling in the Irssi SILC client to
2418 update the channel records so that the kicked client does not
2419 appear to be on the channel. The affected file is
2420 irssi/src/silc/core/silc-channels.c.
2422 * Always update the conn->current_channel when executing command
2423 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2425 * Fixed the KILL notify handling in Irssi SILC client to remove
2426 the killed client on all channels.
2428 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Fixed the silc_parse_command_line to remove extra spaces
2431 from the start and end of the arguments. Affected file is
2432 lib/silcutil/silcutil.c.
2434 * Cancel and free any active protocol in the function
2435 silc_server_close_connection. Affected file silcd/server.c.
2437 * Cancel and free any active protocol in the function
2438 silc_client_close_connction. Affected file is
2439 lib/silcclient/client.c.
2441 * Do not execute the KILL command for clients that are in
2442 history (ie. they are not in the network). Affected file is
2445 * Fixed KILL notify handling, client does not crash anymore.
2446 Affected file irssi/src/silc/core/silc-channels.c.
2448 * Reduced the default packet buffer size from 2048 to 1024 in
2449 lib/silccore/silcpacket.c.
2451 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2452 counter to the SKE context that is incresed when the SKE library
2453 performs async operation outside the library. If the outside
2454 process frees the SKE context and FREED status will be set
2455 and the library will detect after the sync operation that the
2456 libary is freed. The affected files are
2457 lib/silcske/silcske[_status].[ch].
2459 * Resolve the client entry information in the function
2460 silc_client_channel_message to assure that NULL pointer is not
2461 passed as client entry to the application. */
2463 * Fixed the task timeout calculation to assure that there is
2464 never negative timeouts. The affected file is
2465 lib/silcutil/silcschedule.c.
2467 * Fixed the channel user mode notification sending in server.
2468 It was sent point-to-point to the router (or to server by router)
2469 but it needs to be destined to a channel. The routines now
2470 supports sending the channel user mode notifys to the channels
2471 when announcing clients and channels. Affected files are
2472 silcd/server.c and silcd/packet_receive.c.
2474 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2475 It did not actually replace the old channel entry in the cache.
2476 Affected file lib/silcclient/client_notify.c.
2478 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Fixed a possible crash in silc_packet_send_prepare. It now
2481 assures always that there is enough space in the buffer and
2482 at the tail area of the buffer (for MAC).
2484 Fixed the inbound buffer reallocation in silc_packet_read.
2485 It was old code and did not handle the reallocation correctly.
2488 The affected file is lib/silccore/silcpacket.c.
2490 * Fixed buffer overflow in silc_parse_nickname in the file
2491 lib/silcutil/silcutil.c.
2493 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2495 * make install generates new server keys only if there is not
2498 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2501 Added check that if the NOREPLY is set then we will not send
2502 the away message. This avoids infinite loop of away messages
2503 if both clients are away. The affected file is
2504 lib/silcclient/client_prvmsg.c.
2506 * Fixed client crash if /NICK was given without arguments.
2507 Affected file lib/silcclient/command.c.
2509 * Server does not send the invite list in INVITE command back
2510 to the client if the list was not altered. Added this notion
2511 to the protocol spec as well. Affected file silcd/command.c.
2513 Fixed possible crash in INVITE command by checking the
2514 value of silc_server_get_client_route command.
2516 * Fixed the INVITE notify type handling. The arguments are now
2517 taken in correct order and client does not crash. The affected
2518 file is irssi/src/silc/core/silc-channels.c.
2520 Removed the "Inviting xxx to channel" message from the
2521 client library away and let the application handle it.
2522 Affected file lib/silcclient/command.c. Added that message
2523 to Irssi SILC client's message formats.
2525 * Fixed CMODE command crash in client. It now checks the
2526 amount of arguments correctly and does not crash. The affected
2527 file is lib/silcclient/command.c.
2529 * Do not create new channel automatically in silc_channels_join
2530 but check whether the channel by that name already exists.
2531 Affected file irssi/silc/core/silc-channels.c.
2533 * Do not send the SERVER_SIGNOFF to router if the disconnected
2534 entity was the router. Affected file silcd/server.c.
2536 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2537 SILC client as it was missing from there.
2539 Added the handling of the KICK notify to the Irssi SILC client
2540 as it was missing. Added "you have been kicked" message to
2541 Irssi SILC client's message modules formats.
2543 Added the handing of the KILL notify to the Irssi SILC client
2544 as it was missing. Added the kill message module formats
2547 The affected file is irssi/src/silc/core/silc-channels.c.
2549 * The router did not save the channel mode the server announced.
2550 Affected file silcd/packet_receive.c.
2552 * Fixed a possible crash in INFO command in server. If the
2553 server did not provide the server info it crashed. Affected
2554 file silcd/command.c.
2556 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Fixed the GETKEY command in the server to check also the
2559 global list. Otherwise the GETKEY would not work correctly
2560 in normal SILC server. Affected file silcd/command.c.
2562 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Fixed GETKEY crash, it crashed if the command did not succseed.
2566 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2569 is now real and not just an macro interface to GMP.
2571 Removed the entire GMP from the source tree and imported new
2572 NSS MPI library instead. Reason for removing GMP is that it is
2573 extremely large and compiles extremely slow. The NSS MPI
2574 is only a few files and compiles in less than 10 seconds.
2575 The speed is also about the same as GMP. The MPI is imported
2576 to lib/silcmath/mpi.
2578 If the system has GMP installed we will still use the GMP.
2579 If it is not then the NSS MPI will be compiled.
2581 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Merged a long nickname (127 characters long) crash bugfix from
2584 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2586 * Merged a freed memory reference bugfix from Irssi CVS tree.
2587 Affected file irssi/src/core/commands.c.
2589 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Added the server's public key sving and verification to the
2592 server when performing the SKE. This was missing and the
2593 remote server's (or router's) public key was accepted without
2594 checking whether we have it previously or trust it at all.
2595 Affected file silcd/protocol.c.
2597 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Check in the silc_server_timeout_remote if protocol is active
2600 and make sure that the protocol's final callback is called so
2601 that all memory if freed. Affected file silcd/server.c.
2603 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * silc_server_whois_send_reply crashed the server if the nickname
2606 was 127 characters long. Affected file silcd/command.c.
2608 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Added sanity check to the silc_server_new_client. If the hostname
2611 is provided inside username then check that the provided hostname
2612 really is the same as the resolved one. If the hostname was not
2613 resolved then check it from the public key. Affected file is
2614 silcd/packet_receive.c.
2616 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2617 if the server disconnected us and the connection is not valid
2618 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2620 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2621 the library to the lib/silcutil/silcutil.[ch].
2623 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * Close log file after open. Affected file
2626 lib/silcutil/silclog.c.
2628 * Check whether sock == NULL in silc_client_send_packet and return
2629 if it is. Affected file lib/silcclient/silcclient.c.
2631 * Check rec->entry == NULL in the Irssi SILC Client before
2632 sending the channel message. Affecte file is
2633 irssi/src/silc/core/silc-servers.c.
2635 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Merged a splitted window bugfix from Irssi CVS tree. The
2638 affected file is irssi/src/fe-text/textbuffer-view.c.
2640 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2641 It did not print nickname.
2643 * Improved the distributions system a bit.
2645 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2648 irssi/src/fe-text/gui-window.c.
2650 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2651 to in-active server. The affected file is
2652 irssi/src/silc/core/client_ops.c.
2654 * Resolve the client in USERS command reply if the entry does
2655 not have username resolved. The affected file is
2656 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2657 command to WHOIS command to really resolve stuff. The USERS
2658 is not used any more in any critical section so WHOIS can
2659 be used even though it might be slower than IDENTIFY.
2661 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2664 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Changed the protocol API a bit more consistent in the
2667 lib/silccore/silcprotocol.[ch].
2669 * Changed the following headers to ROBODoc format:
2671 lib/silccore/silcpayload.h
2672 lib/silccore/silcprotocol.h
2673 lib/silccore/silcsockconn.h
2675 All core library headers are now formatted.
2677 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Fixed a bug in Irssi SILC client; do not show that you are
2680 server/router operator if you really are not. Affected file is
2681 irssi/src/silc/core/client_ops.c.
2683 * Renamed silc_command_free_payload to silc_command_payload_free.
2684 Affected file lib/silccore/silccommand.h
2686 * Added silcmath.h to include the prototoypes of various routines
2687 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2690 * Changed the following headers to ROBODoc format:
2692 lib/silccore/silcchannel.h
2693 lib/silccore/silccommand.h
2694 lib/silccore/silcid.h
2695 lib/silccore/silcidcache.h
2696 lib/silccore/silcmode.h
2697 lib/silccore/silcnotify.h
2698 lib/silccore/silcpacket.h
2699 lib/silcmath/silcmath.h
2701 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Added checking to the server code not to start the server if
2704 ciphers and stuff are not configured properly. Affected files
2705 silcd/serverconfig.[h] and silcd/server.c.
2707 * Changed the layout of the header files of the public interfaces
2708 in the SILC libraries. The new layout supports ROBODoc
2709 documentation tool (and some others) so that it is easy to create
2710 a library reference manual. All the other headers and source
2711 code must still follow the CodingStyle document. Also source
2712 code must not include these ROBODoc stuffs, only the headers.
2713 Furthermore, all public interface headers must now be named
2714 by using `silc' prefix, example: silcapi.h, silccipher.h.
2715 Some files were renamed due to this. All the other headers
2716 must not be used as public interfaces. I will update the
2717 CodingStyle document later. Changed following headers, so far:
2719 lib/silcclient/silcapi.h
2720 lib/silccore/silcauth.h
2721 lib/silccore/silcprivate.h
2722 lib/silccrypt/silcdh.h
2724 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Removed silc_client_packet_send_flush from the client library
2729 as it is not needed. Affected file lib/silcclient/client.[ch].
2731 * Added printing of message of unresolved authentication method
2732 to the Irssi SILC client. Added it to the module formats.
2733 Removed the same message from the client library.
2735 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Added new distribution feature, DISTLABEL. Every distribution
2738 can define own preprocessor label that can be used in the
2739 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2740 file distributions, acconfig.h.pre and prepare.
2742 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Added Makefile.defines_int to include the actual definitions
2745 for Makefile.defines.in. Tested the new distribution system,
2746 created distributions and tested installation.
2748 * Added AWAY message printing to the Irssi SILC client. Added
2749 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2751 * Added SCONNECT command to call the SILC's CONNECT command.
2752 Cannot use CONNECT directly since Irssi uses that internally.
2753 Affected file irssi/src/silc/core/silc-servers.c.
2755 Added ACTION local command. It is same as ME command but takes
2756 the channel as mandatory argument.
2758 Rewrote some of the Irssi's help files to suite for SILC
2761 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Added Makefile.defines[.in] that should for now on be included
2764 in all Makefile.am file in the source tree. That file includes
2765 all common compilation definitions for SILC source tree.
2767 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Minor changes to the ./prepare script to change the package
2770 name according the distribution name to the configure.in.
2772 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Created new distribution system. Added file `distributions'
2775 that defines all the distributions that can be created out of
2776 the SILC source tree. The ./prepare script now reads that
2777 file to determine how to prepare the distributions. The
2778 first argument to the ./prepare is the name of the distribution
2779 and second is the version of the distribution. If given
2780 without arguments it creates the default (toolkit) distribution
2781 with the default version (defined in ./prepare).
2783 All Makefile.am files that are subject to the distributions
2784 are now named as Makefile.am.pre. These are ./Makefile.am
2785 and lib/Makefile.am. Others may be changed later.
2787 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Added invite list, ban list, some key management and connection
2790 error message printing to module formats in the Irssi SILC client.
2792 * Added new silc_client_set_away_message to set the away message
2793 that is back to the person who sent private message. The
2794 affected file lib/silcclient/silcapi.h and the
2795 lib/silcclient/client_prvmsg.c.
2797 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Fixed the private message sending in the Irssi SILC client,
2800 added local command KEY to the Irssi SILC client.
2802 Added key management and key agreement message formats to the
2803 irssi/src/fe-common/silc/module-formats.[ch].
2805 Added USERS (alias WHO) printing, server/router operator
2806 indication and LIST command printing to the module formats.
2808 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Fixed channel joining notify handling, cumode notify handling
2811 from Irssi SILC client.
2813 * Added SILC specific module-formats to the Irssi SILC client so
2814 that SILC specific message hilighting, colors etc is possible.
2815 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2817 Added channel mode, channel user mode, actions, notices,
2818 whois and whowas printing to the the module-formats.c.
2820 * Fixed a bug in channel deletion in the server. The channel
2821 is not left to the cache even if the channel founder auth mode
2822 is set when there are no users anymore on the channel. Affected
2823 file silcd/server.c.
2825 * The silc_net_localhost now resolves the entire hostname including
2826 the domain name. Affected file lib/silcutil/silcnet.c.
2828 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Changed the ask_passphrase client operation to be ascynchronous.
2831 It has now a completion callback and a context that the
2832 application must call after it has got the passphrase from
2833 the user. Affected files lib/silcclient/silcapi.h,
2834 lib/silcclient/protocol.c, lib/silcclient/command.c and
2837 Added SilcAskPassphrase callback that the application calls
2838 to deliver the passphrase to the library.
2840 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2841 The public key verification and especially a certificate
2842 verification is asynchronous procedure.
2844 Added new SILC_SKE_STATUS_PENDING status to indicate the
2845 request is pending and a callback will be called to finalize
2848 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2849 indicate that remote end did not send its public key (or
2850 certificate), even though we require it. Added check for this
2851 condition in the SKE. This was a security bug, now fixed.
2853 Defined new SilcSKEVerifyCbCompletion callback that is called
2854 when the verification process is completed.
2856 The affected files lib/silcske/silcske_status.h and
2857 lib/silcske/silcske.[ch].
2859 * Changed the verify_public_key client operation to be async
2860 as well. Defined SilcVerifyPublicKey callback that is used to
2861 indicate the success of the public key verification process.
2863 Changed the server and client to use the new async client
2866 * Changed the Irssi SILC client's internal scheduler to be called
2867 twice as many times as it used to be. As a result the client
2868 should be a bit faster now. Affected file is
2869 irssi/src/silc/core/silc-core.c.
2871 * Added support to Irssi SILC client of asynchronous public key
2872 verification and passphrase inquiry. Affected file is
2873 irssi/src/silc/core/silc-core.c.
2875 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2877 * Do not say "You have left channel %s" in client library.
2878 Moved it to the application. Affected files are
2879 lib/silcclient/command.c and silc/client_ops.c.
2881 * Fixed silc_client_get_clients. Command context was not
2882 duplicated and was freed memory in the callback. Affected
2883 file lib/silcclient/idlist.c.
2885 * Do not say "you are now talking..." on JOIN command in the
2886 client library. The appliation must handle it.
2888 * Do not say ".. changed topic to" in command reply in the
2889 client libary. The application must handle it.
2891 * Fixed TOPIC command sending in the client library.
2893 * Fixed a memory leak in silc_client_command_free in the file
2894 lib/silcclient/command.c.
2896 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Imported a modified version of Irssi client to the source tree.
2899 The Irssi will be used to create a new client called
2900 Irssi SILC. Imported to irssi/.
2902 Added silc_core_init_finish function to the Irssi. Affected
2903 file irssi/configure.in.
2905 A lot changes in the Makefile.ams around the irssi tree.
2907 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Do not rehash if the new size is same as the old size of the
2910 hash table, in the silc_hash_table_rehash*. The affected file
2911 lib/silcutil/silchashtable.c.
2913 * Replaced hash_table_del_by_context calls from the server
2914 (when channel->user_list and client->channels) to the
2915 hash_table_del as it is sufficient and faster.
2917 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added silc_hash_table_list, silc_hash_table_get and the
2920 SilcHashTableList structure to provide an alternative way to
2921 traverse the hash table. The affected files are
2922 lib/silcutil/silchashtable.[ch].
2924 * Changed the server's idlist routines to use the hash table
2925 routines to optimize the code.
2927 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Replaced the client entry's `channel' list and channel entry's
2930 `user_list' list to hash tables for optimized lookup. Changed
2931 the code to use the hash table interface around the code.
2932 Affected file lib/silcd/idlist.[ch].
2934 * Added `auto_rehash' boolean argument to the function
2935 silc_hash_table_alloc to indicate whether the hash table should
2936 auto-rehash when it thinks is appropriate time. It will
2937 increase the hash table size if the there is twice as much
2938 entries in the table than the size of the table, and will
2939 decrease the size if there are twice as less entries than
2940 the size of the table.
2942 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2946 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * silc_idcache_purge_by_context deletes the entry now by context
2949 as it is supposed to do. Affected file lib/silccore/idcache.c.
2951 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2952 client is not anymore valid (WHOWAS givens the info) and not
2953 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2955 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Removed the `data' and `data_len' arguments from the ID Cache
2958 interfaces and added `name' argument. ID Cache does not handle
2959 anymore the binary data only a names associated with given ID.
2961 * When hashing a Client ID with silc_hash_id the entire ID is
2962 not hashed anymore, instead only the hash of the Client ID is
2963 hashed. This way we can access the Client ID from the cache
2964 with Client ID but with the hash of the ID (which is a hash of
2965 the nickname) as well without any difference in performance.
2967 Added also silc_idcache_find_by_id_one_ext to do one on one
2968 searching when we have the actual ID. Added also function
2969 silc_hash_client_id_compare. The affected files are
2970 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2972 * When hashing the name associated with a ID it is always done
2973 in lowercase. This way we can access the cache without worrying
2974 about case-sensitivity, even though, for example nicknames are
2977 * Fixed a bug in server with channel message sending. It put
2978 wrong ID type as destination ID. The affected file
2979 silcd/packet_send.c.
2981 * silc_idcache_del_by_context now deletes from all hash tables
2982 by context. Affected file lib/silccore/idcache.c.
2984 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Changed the client library to use the new ID Cache interface.
2987 Changes around the source tree.
2989 * Added silc_hash_table_rehash_ext to rehash with specific
2990 hash function. Affected file lib/silcutil/silchashtable.[ch].
2992 * Added silc_hash_string_compare to compare two strings in the
2993 hash table. Affected file lib/silcutil/silcutil.[ch].
2995 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Added new function silc_idcache_del_by_context into the
2998 lib/silccore/idcache.[ch].
3000 * Changed the server's ID list routines to use the new ID Cache
3001 interface. Changes around the source tree.
3003 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Added silc_hash_table_del[_by_context]_ext functions in to the
3006 lib/silcutil/silchashtable.[ch].
3008 Removed silc_hash_table_find_all* routines and added new
3009 silc_hash_table_find_foreach to replace them.
3011 Added silc_hash_table_replace_ext function as extended
3012 replacing function. Separated the simple hash table interface
3013 from the extended hash table interface in the file
3014 lib/silcutil/silchashtable.h.
3016 * Fixed minor bugs and changed it to use some of the new
3017 hash table functions in lib/silccore/idcache.c
3019 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Added new function silc_hash_table_find_all to return all keys
3022 in the hash table by the specified key. As the hash table is
3023 collision resistant it also makes it possible to have several
3024 duplicate keys in the hash table. This function may be used to
3025 find all of the keys from the hash.
3027 Added user_context arguments to the SilcHashFunction,
3028 SilcHashCompare and SilcHashDestructor to deliver user specified
3031 Added new fuctions silc_hash_table_find[_all]_ext to do
3032 extended lookup with specified hash and compare functions and
3033 specified user contexts.
3035 Added new function silc_hash_table_add_ext to add the key
3036 with specified hash function and user context.
3038 Added new function silc_hash_table_foreach to traverse all
3039 entrys in the hash table. Added SilcHashForeach callback
3042 Added new function silc_hash_table_del_by_context to delete
3043 the entry only if the context associated with the key matches.
3045 Affected files are lib/silcutil/silchashtable.[ch].
3047 * Removed silc_hash_[server/client/channel]_id and added just
3048 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3049 silc_hash_id_compare to compare two ID's using as the hash table
3050 comparison function. Added also silc_hash_data to hash
3051 binary data and silc_hash_data_compare to compare it.
3053 * Removed silc_idlist_find_client_by_hash as it is not needed
3054 anymore. Affected file silcd/idlist.[ch].
3056 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3057 to use internally the SilcHashTable. The new ID Cache is a lot
3058 faster than the old one. Some of the ID Cache interface was also
3059 rewritten and obsolete and stupid functions were removed.
3061 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3063 * Added entry_count field to the SilcHashTable to keep the number
3064 of the entries in the table. Implemented the function
3065 silc_hash_table_rehash. Added new function
3066 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3068 Fixed a minor bug in silc_hash_table_free.
3070 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3071 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3072 into the lib/silcutil/silcutil.[ch].
3074 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Implemented a collision resistant hash table into the
3077 lib/silcutil/silchashtable[ch]. See the header and the source
3078 for the SilcHashTable API.
3080 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Merged dotconf version 1.0.2 into lib/dotconf.
3084 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Do not compile anything in lib/silcsim/* if the SIM support
3087 is not enabled. The tree should now compile without problems
3090 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Compiled the SILC under cygwin. Compiled and tested briefly
3093 without problems. More tests needed. The SIMs didn't compile
3096 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3098 * Fixed possible crash in silc_get_username in the
3099 lib/silcutil/silcutil.c.
3101 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Fixed a va_arg in silc/client_ops.c.
3105 * Oops, RC5 routines were named AES and caused some problems
3106 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3108 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3110 * Added new SilcIDIP structure into the lib/silccore/id.h and
3111 replaced the old `ip' fields from all SILC ID's to that type.
3112 This is a step towards IPv6 support.
3114 The silc_id_get_len takes now the ID as an extra argument.
3115 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3116 both IPv4 and IPv6 based ID's.
3118 The affected files are lib/silccore/id.[ch] and other files
3119 around the tree using these routines.
3121 * Removed the ID length arguments in server from various
3122 silc_server_send_notify_* routines -> they are not needed
3125 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Fixed memory leak in silc_encode_pem_file in the file
3128 lib/silcutil/silcutil.c.
3130 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Check minor version as well in the SKE. Affected files are
3133 silcd/protocol.c and lib/silcclient/protocol.c.
3135 * Added --identifier option to the server so that an identifier
3136 can be when creating the public key for the server. Affected
3137 file is silcd/silcd.c.
3139 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3140 lib/silccrypt/silcpkcs.c.
3142 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Register default ciphers and stuff when using -C option with
3145 the server. Affected file sildc/silcd.c.
3147 * Put back the servers public key filename format, it is better
3148 than the new one. For now, the client keys are saved with the
3149 new filename format. The affected file silc/client_ops.c.
3151 * Implemented the Cipher API for the rest of the ciphers that
3152 did not implement it or implemented it the wrong way.
3154 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Register default ciphers and stuff when using the -S option
3157 in the client. Affected file silc/silc.c. Same also when
3158 creating new key pair with -C option.
3160 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Fixed the silc_verify_public_key client operation function to
3163 save the public keys differently. The fingerprint is now
3164 used as filename and not the hostname. This way also the
3165 client keys are saved uniquely and not with hostnames. The
3166 affected file is silc/client_ops.c.
3168 * Trimmed the silc_hash_fingerprint function to remove extra
3169 whitespaces from the end of the fingerprint. The affected
3170 file is lib/silccrypt/silchash.c.
3174 * Added silc_cipher_register_default function to register all
3175 default ciphers. It can be used when configuration files
3176 does not exist and the application does not want any specific
3177 ciphers in any specific order.
3179 The SilcDList is now used as silc_cipher_list dynamically
3180 allocated cipher list. Removed the static list all together
3181 and now all ciphers must be allocated to the dynamic list.
3182 The silc_cipher_alloc routine was changed to check only the
3185 All silc_cipher_* routines that used to return int returns
3188 The affected files lib/silccrypt/silccrypt.[ch].
3190 * The same thing was done to silc_hash_* as for silc_cipher_*
3191 routines. Affected files lib/silccrypt/silchash.[ch].
3193 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3194 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3195 Added also silc_pkcs_[un]register[_default] functions.
3196 Removed the data_context from the PKCS API.
3198 * Added silc_hmac_register_default function to register default
3199 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3200 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3201 to unregister all hmacs at once.
3203 * Register the default ciphers, hash functions, PKCSs and HMACs
3204 if client's configuration file does not exist. The affected
3207 * The client did not load the hash functions from the SIM
3208 modules at all. Added support for this. Affected file is
3209 silc/clientconfig.c.
3211 * When decoding public key with silc_pkcs_public_key_decode, check
3212 the supported algorithm only if PKCS are registered. Affected
3213 file lib/silccrypt/silcpkcs.c. The same was done with the
3214 silc_pkcs_private_key_decode.
3216 * Fixed the SILC List routines to keep the list always in order.
3217 It used to change the list's order when traversing the list but
3218 not it preserves the order. Affected file lib/trq/silclist.h.
3220 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Added the client library to use the SilcSocketConnection's
3223 reference counter (by silc_socket_dup) to prevent the bug that
3224 the socket object may be freed underneath async operation.
3226 * The name resolv library checking fixes in the configure.in.pre.
3229 * Created new version of the protocol drafts for future
3230 development. The -03 drafts are the ones that will be changed
3231 in the trunk now and the -02 will remain as they are.
3233 * Send list of CUMODE notifys to the router when announcing
3234 the channel users to the router. Affected file silcd/server.c.
3235 If the router receiving channel founder CUMODE for a channel
3236 that already has channel founder it will send CUMODE notify
3237 to the sender to remove the channel founder rights from the
3238 announced client. Affected file silcd/packet_receive.c.
3240 * The CUMODE notify may now use Server ID as well as the entity
3241 who changes the mode. Updated protocool specs.
3243 * Updated INSTALL and README files.
3245 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * New web pages in the http://silc.pspt.fi. The pages was
3252 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Implemented the [DenyConnectin] config section in the server.
3255 Added silc_server_config_denied_conn to check whether incoming
3256 connection is denied. Affected file silcd/serverconfig.[ch].
3258 * Do not check the ports when checking the incoming configuration
3259 data if the port is 0, meaning any. Affected file is
3260 silcd/serverconfig.c.
3262 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * Fixed buffer overflow in silc_string_compare in the file
3265 lib/silcutil/silcutil.c.
3267 * Fixed double free in silc_server_command_leave in the file
3270 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Fixed the version checking in the server. Affected file is
3275 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Fixed the configuration data fetching when accepting new
3278 connections in the server. Affected file silcd/server.c.
3280 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Added `sender_entry' argument to the function
3283 silc_server_packet_relay_to_channel so that we can check
3284 whether some destination actually belongs to the same route
3285 the sender belongs (ie, we must not resend the packet to the
3286 sender). Affected file silcd/packet_send.[ch].
3288 * Added `servername' field to the SilcClientEntry in the server
3289 to hold the name of the server where client is from. Affected
3290 file is silcd/idlist.h.
3292 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Moved the channel message encrypting in the router betwen
3295 router connections from silc_server_channel_message to the
3296 silc_server_packet_relay_to_channel since we want to check
3297 whether we have anybody channel before encrypting anything.
3298 Affected files silcd/packet_[receive/send].c.
3300 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Fixed the [AdminConnection] server config section to support
3303 multiple entries. Affected file silcd/serverconfig.c.
3305 * Added support into the server to check the validity of the
3306 incoming connection before executing any KE or authentication
3309 * The connection configuration is now saved to the KE and
3310 connection auth protocol contexts and not fetched anymore in
3311 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3313 * The local hosts listenning address and port is also resolved
3314 now when starting the server. We want to have the socket object
3315 to include the real address and port for the listener. Added
3316 new function silc_net_check_local_by_sock into the files
3317 lib/silcutil/silcnet.[ch].
3319 * Fixed a broadcast bug in server -> do not broadcast if we
3322 * Fixed a routing bug. Do not route broadcast packets ever.
3323 Broadcast packets must be processed always and not routed since
3324 they may be destined to some other host than yourself and thus
3325 would get routed without no good reason. Affected file is
3328 * Added function silc_server_config_is_primary_route to check
3329 whether primary router connection has been configured (a router
3330 configuration that we are initiating). If there is not, we
3331 will assume that there is only two routers in the SILC network
3332 and we will use the incoming router connection as our primary
3333 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3335 * Changed the order of the broadcasting. Broadcast _after_ the
3336 packet has been processed not before. Affected file is
3339 * Fixed a [ClientConnection] parsing bug. The port was never
3340 parsed correctly thus resulting to port 0. Affected file
3341 silcd/serverconfig.c.
3343 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3344 argument and did not set the broadcast packet flag. Affected
3345 file silcd/packet_send.c. Fixed same bug in the function
3346 silc_server_send_notify as well.
3348 * If we receive NEW_ID packet for our own ID in the server, ignore
3351 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Removed the nickname from the Private Message Payload.
3356 Updated the code and the protocol specs.
3358 * Updated protocol specs for submitting to the IETF.
3360 * Tweaked the Random Number Generator a bit. Affected file
3361 lib/silccrypt/silcrng.c. Exported a new function
3362 silc_rng_[global]_add_noise which can be used to add more
3365 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Do not parse packets with different timeout when protocol
3368 is active -> may cause problem with rekey. Affected file
3371 * When server receives signoff notify it must not create
3372 new channel key if the client is on any channels since the
3373 sender of the signoff notify will create it.
3375 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Added printing of error messages during SKE protocol from the
3378 failure packet sent by server during SKE. Affected file
3381 * Removed the client's failure_callback handling with timeout
3382 and handle it immediately when received.
3384 * The SKE library returned wrong type in SUCCESS and FAILURE
3385 packets. They must be 32 bit MSB not 16 bit MSB.
3387 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Ok, rewrote the logic of the re-key and now it seems to work.
3390 I tested it on high traffic with frequent re-keys without
3391 problems. Added hmac_receive (and renamed hmac to hmac_send)
3392 in SilcClientConnection in lib/silcclient/client.h and
3393 in SilcIDListData in silcd/idlist.h. Also, removed the
3394 SilcPacketParserContext's cipher and hmac fields as they are
3395 not needed anymore and actually caused some problems when
3396 the ciphers and hmac's changed underneath the packet parser.
3398 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * If re-key protocol is active then process the incoming packets
3401 synchronously since we must assure that icoming packets encrypted
3402 with the old key is processed before the new keys is set to
3403 use. This is true other packets than for REKEY packets.
3404 Affected file silcd/server.c. The same was done to client library
3405 as well, affected file lib/silcclient/client.c.
3407 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Fixed bug in client and server to accept the force send if
3410 the packet is send from silc_[server/client]_packet_process
3411 function. Otherwise the packets are never delivered, oops.
3413 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Disable force sending of packets when REKEY protocol is active.
3416 We must assure that no packet is sent directly when rekey is
3417 performed. All packets must be sent through packet queue.
3418 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3419 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3420 function is silc_[server/client]_packet_send_real to check
3423 * Replaced the SIM paths from example config files to
3424 /usr/local/modules. Also, make install creates now
3425 /usr/local/silc/logs directory to hold all the SILC server
3428 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Made the configure.in.pre work on Solaris. Patch by salo.
3432 * Made all ciphers compatible with non-x86 machines. Defined
3433 CBC mode macros into lib/silccrypt/ciphers_def.h.
3435 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Fixed the make install.
3439 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * When MAC computation fails the silc_packet_decrypt returned 0
3442 even though it was supposed to return -1. Fixed this. The
3443 affected file is lib/silccore/silcpacket.c.
3445 * Do not replace the config files in /etc/silc (in make install)
3446 if they already exist. Affected file ./Makefile.am.
3448 * Do not send re-key packets immediately but through packet queue.
3449 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3451 * Changed silc_net_check_host_by_sock to return FALSE if the
3452 IP/DNS could not be resolved. Though, it returns the IP address
3453 now even if it could not resolve it (but returns also FALSE).
3454 Affected file lib/silcutil/silcnet.[ch].
3456 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Added silc_pkcs_decode_identifier to decode the public key's
3459 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3460 Added also silc_pkcs_free_identifier. Added also new context
3461 SilcPublicKeyIdentifier.
3463 * Added -S option to the silc client. It is used to dump the
3464 contents of the specified public key file.
3466 * Changed the PKCS api to return the public key length when
3467 setting the public key.
3469 * Fixed a fatal bug in the public and private key file loading.
3470 Affected file lib/silccrypt/silcpkcs.c.
3472 * Execute the packet parsing for client with zero (0) timeout
3473 if the protocol is active. Affected file silcd/server.c.
3475 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Made the key generation options to the silcd program. Added
3478 -C option, equivalent to client's option.
3480 * Added new [ServerKeys] config section to the server. It
3481 configures the server's public and private key.
3483 * Defined generic Public Key Payload into the protocol
3484 specification to send specific type of public keys and
3487 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3488 public key or certificate.
3490 * Implemented the GETKEY command to the server and to the
3491 client library and on user interface.
3493 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Made preliminary `make install' work.
3497 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Added SilcServerRekey context into silcd/idlist.h.
3501 * Added the PFS support as defined in the specification to the
3502 SKE protocol. Affected files lib/silcske/*.c.
3504 * Added `ske_group' field to the SilcServerRekey context to hold
3505 the number of the SKE group that is used with PFS in re-key.
3506 Affected file silcd/idlist.h.
3508 * Added PFS re-key support to the server. Affected file is
3511 * Added silc_protocol_cancel to cancel execution of the next
3512 state of the protocol. Affected file is
3513 lib/silccore/silcprotocol.[ch].
3515 * Added the re-key support with and without PFS to the client
3516 library. Re-key is performed once in an hour, by default.
3518 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3519 Added silc_client_rekey_callback and silc_client_rekey_final.
3520 Affected files are lib/silcclient/protocol.[ch] and
3521 lib/silcclient/client.[ch].
3523 * Removed the `hmac_key' and `hmac_key_len' fields from the
3524 SilcClientConnection structure; not needed. Affected file is
3525 lib/silcclient/client.h.
3529 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Do not ask whether user wants to use the negotiated private key
3532 for private messages, just use it. Affected file is
3533 silc/local_command.c.
3535 * Added `send_enc_key' and `enc_key_len' fields to the
3536 SilcIDListData structure since they are needed in the re-key
3537 phase. Affected file is silcd/idlist.[ch].
3539 * Implemented the simple re-key protocol into the server.
3540 Affected files silcd/server.c and silcd/protocol.[ch]. The
3541 re-key will be performed once in an hour, by default.
3543 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3544 Added silc_server_rekey, silc_server_rekey_callback and
3545 silc_server_rekey_final.
3547 * Removed Tunneled flag from the protocol. Updated the code
3548 and the specifications.
3550 * Adde `pfs' field to the SilcIDListData to indicate whether
3551 the PFS is to be performed in the re-key. Affected file is
3554 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3557 int64 of at least the xintXX size. If void * is less that 4
3558 bytes uint32 * will be used. Defined bool as boolean.
3560 * Changed _ALL_ unsigned long and unsigned int to uint32,
3561 unsgined short to uint16 in the source tree.
3563 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3564 not handle clients that has entry->data.registered == FALSE.
3565 They are not in the network anymore. Affected file is
3568 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Implemented the sending of the SERVER_SIGNOFF notify in the
3571 server. Affected file is silcd/server.c.
3573 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3574 Added also silc_notify_payload_encode_args into the
3575 lib/silccore/silcnotify.[ch].
3577 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3578 Affected file silcd/packet_receive.c.
3580 * Implemented the SERVER_SIGNOFF notify handling in the client
3581 library. Affected file lib/silcclient/client_notify.c. Also,
3582 implemnted the printing of the SERVER_SIGNOFF info to the
3583 application. Affected file silc/client_ops.c.
3585 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3586 if the deleting was successful. Affected file silcd/idlist.[ch].
3588 * Added support for public key authentication in the connection
3589 authentication protocol in the client library. Affected file
3590 lib/silcclient/protocol.c.
3592 * Changed the server's silc_idlist_get_clients_by_* interface
3593 to support already allocated array so that new entries may be
3594 added to pre-allocated array. Affected file silcd/idlist.[ch].
3595 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3596 and command replies.
3598 * All command reply functions in the server now calls the
3599 pending command callback even if error occured. This way the
3600 error will be delivered to the client as well. Affected files
3601 silcd/command.c and silcd/command_reply.c.
3603 * Fixed INFO command to return local server's info if no server
3604 was provided. Affected file lib/silcclient/command.c.
3606 * Removed RESTART command for good. Updated the code and the
3609 * Rewrote parts of the task system. It is a bit simpler now.
3610 Removed unsued task priorities. The affected files are
3611 lib/silcutil/silctask.[ch].
3613 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Moved the USERS printing from the library to the application.
3616 Affected files lib/silcclient/command.c and silc/client_ops.c.
3618 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Added channel key re-key support. The re-key is perfomed
3623 only by the router and is done once in an hour. Added `rekey'
3624 field to the SilcChannelEntry in the server. Affected files
3625 silcd/server.c and silcd/idlist.h.
3627 * Added silc_task_unregister_by_context into the file
3628 lib/silcutil/silctask.[ch].
3630 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Added SILC_UMODE_GONE mode to indicate when the client is not
3633 present in the SILC network. Added also support to the local
3634 command AWAY that will set this mode. Added support of showing
3635 "xxx is gone" in WHOIS command. The USERS command shows the
3636 gone status as well.
3638 * Fixed setting server and router operator privileges in the
3639 server's UMODE command. Affected file silcd/command.c.
3641 * Merged the SKE KE1 and KE2 payloads into one payload. The
3642 new KE payload is equivalent to the old KE2 payload.
3644 Cleaned up the SKE Start Payload parsing. It now uses the
3645 simple buffer unformatting to do the parsing. A lot faster
3648 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3649 to the SKE that is used to indicate whether both of the SKE
3650 parties should perform authentication. By default only the
3651 responder performs authentication. By setting this flag also
3652 the initiator must do authentication. By default it is unset
3653 since in normal SKE case, client to server connection, only
3654 the responder should do authentication. When doing SKE between
3655 two clients both should perform authentication. Updated the
3656 code and the protocol specs.
3658 * A little fix to IDENTIFY command in the server. Search the
3659 client first by hash not nickname. Affected file is
3662 * Fixed the silc_client_close_connection to support closing
3663 the client to client connections wihtout deleting too much
3664 data. Affected file lib/silcclient/client.c.
3666 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3667 are received if protocol used to be active but is not anymore
3668 the application would crash due to NULL pointer dereference.
3669 Affected files silcd/server.c and lib/silcclient/client.c.
3671 * Added `hash' field to the SilcClientConnection to include
3672 the hash function negotiated in the SKE protocol.
3674 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3675 to set the channel founder authentication data. A client can
3676 claim the founder rights later by providing the authentication
3677 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3678 This way the channel founder can regain the channel founder
3679 privileges even it is left the channel. This works only on
3680 local server and the client must be connected to the same
3681 server to be able to regain the founder rights. Updated the
3682 protocol specs accordingly.
3684 Added support to the CMODE command in the client to set the
3685 founder auth data. Read the README to see how to set it.
3687 Added support to the CUMODE command to claim the founder
3688 rights. Read the README to see how to do it.
3690 Added support for the founder authentication to the Channel
3691 Entry in the server. Affected file silcd/idlist.h.
3693 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3694 server's CMODE command. Affected file silcd/command.c.
3696 * Added the following new functions into lib/silccore/silcauth.[ch]:
3697 silc_auth_get_method and silc_auth_get_data.
3699 * The server now saves the remote hosts public key to the
3700 SilcIDListData pointer. Affected file silcd/protocol.c.
3702 * The normal server now does not remove the channel entry from
3703 the cache if the founder authentication data is set. It used
3704 to remove it if the founder was the last one on the channel on
3705 the server and left the channel. The auth data is saved and
3706 if the channel is re-joined later the old entry is used with
3707 the old auth data. Affected files silcd/command_reply.c and
3710 * Removed the `pkcs' field from the SilcIDListData structure
3711 in the server; it is not used. Affected file silcd/idlist.h.
3713 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Fixed packet processing on slow links. Partial packets were
3716 never re-processed because the incoming data buffer was cleared
3717 by the application. Application must not directly clear the
3718 sock->inbuf, the packet processing routines handle it. Fixed
3719 this in client library and in server.
3721 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Fixed the WHOIS and IDENTIFY send reply function to really
3724 check whether to send list or just one entry. Affected file
3727 * Cleaned up the LEAVE command's channel key distribution. The
3728 affected file silcd/command.c.
3730 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3731 can enforce the channel mode as well. In that case the ID
3732 includes the ID of the server. The code now enforces the
3733 mode change if the router have different mode than the server.
3735 * The notify client operation with CMODE_CHANGE notify can now
3736 return NULL client_entry pointer if the CMODE was not changed
3737 by client. Application must check for this.
3739 * Added <Server ID> argument to INFO command to support server
3740 info fetching by Server ID.
3742 * Added silc_server_announce_get_channel_users to get assembled
3743 packets of channel users of the specified channel. Affected
3744 file silcd/server.[ch].
3746 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3747 was freed underneath the ID Cache.
3749 * Re-announce clients when the server received CHANNEL_CHANGE
3750 notify from the router. Affected file silcd/packet_send.c.
3752 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3755 crashed since it did not handle the fact that there is no cipher
3756 called "3" and didn't check the error condition. Now fixed.
3758 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3759 flag. It can be used to send message requests.
3761 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Implemented the RESTART command in the client.
3765 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3766 notice type messages. Added notice printing to the user
3769 * The channel keys are not re-generated if the channel's mode
3770 is PRIVKEY, ie private key on the channel exists. Affected
3771 files silcd/server.c and silcd/command.c.
3773 * Fixed a little bug in channel message delivery when channel
3774 private keys are set in the server. Affected file is
3775 silcd/packet_send.c.
3777 * Changed the setting on channel->on_channel = TRUE from the
3778 silc_client_save_channel_key to the JOIN command reply. The
3779 key payload is not received if the private channel key is set.
3780 Affected file lib/silcclient/command_reply.c and the
3781 lib/silcclient/client_channel.c.
3783 * When the CMODE_CHANGE notify is sent and the channel private
3784 key mode is removed the channel key must be re-generated in
3785 other cells as well. Added this support for the router in the
3786 silcd/packet_receive.c.
3788 * Added new local command NOTICE to send notice message on
3789 channel. Affected file silc/local_command.[ch].
3791 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Added new local command ME to the client. It is used to send
3794 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3795 some action. Affected file silc/local_command.[ch].
3797 * Changed channel_message and private_message client operations
3798 to deliver the message flags to the application. Added also
3799 the `flags' arguments to the silc_client_send_channel_message
3800 and silc_client_send_private_message functions. Affected file
3803 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Redefined the Private Message Payload to support private message
3806 keys and to support the new private message flags. Updated
3807 the protocol specs. Flags makes it possible to have for example
3808 CTCP style messages.
3810 * Added new type SilcPrivateMessagePayload and defined an API
3811 for it in the lib/silcclient/silcprivate.[ch].
3813 * Tested private message private keys successfully. Tested the
3814 private message key set, unset and list commands with the new
3817 * Redefined the Channel Message Payload to include the channel
3818 message flags (equal with private message flags) to support
3819 for example CTCP style messages.
3821 * Defined some of the message (for channel and private message)
3822 flags. Updated the protocol specs and added the flags to the
3823 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3825 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Added SilcKeyAgreementStatus type to the key agreement routines
3828 to indicate the current status and error if one occured.
3829 The status types are defined in the lib/silcclient/silcapi.h.
3831 * Added new local command KEY that is used to set and unset private
3832 keys for channels, set and unset private keys for private messages
3833 with remote clients and to send key agreement requests and
3834 negotiate the key agreement protocol with remote client. The
3835 key agreement is supported only to negotiate private message keys,
3836 it currently cannot be used to negotiate private keys for channels,
3837 as it is not convenient for that purpose.
3839 * Fixed a minor pending callback setting bug in the function
3840 silc_client_get_client_by_id_resolve, now the function works.
3841 Affected file lib/silcclient/idlist.c.
3843 * Added function silc_net_get_local_port to get local bound
3844 port by socket. Added to lib/silcutil/silcnet.[ch].
3846 * Added `sockets' and `sockets_count' fields to the SilcClient
3847 object. They hold the sockets of the listenning sockets in
3848 the client. Listenning sockets may be for example the key
3849 agreement server. Affected file lib/silcclient/client.[ch].
3850 Added functions the silc_client_add_socket and the
3851 silc_client_del_socket. They are exported to the application
3854 * Added ~./silc/clientkeys to support other client's public keys.
3856 * Renamed verify_server_key client operation to verify_public_key
3857 and added one argument to indicate the type of the connection
3858 (server, client etc.).
3860 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Added silc_server_connection_auth_request to handle the
3863 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3864 silcd/packet_receive.[ch].
3866 * Added silc_server_send_connection_auth_request into the
3867 silcd/packet_send.c to send the connection auth request packet.
3869 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3872 * Fixed the public key authentication in responder side in the
3873 server. The `auth_data' pointer includes the SilcPublicKey
3874 not the path to the public key. Affected file silcd/protocol.c.
3876 * Implemented the public key authentication in the initiator side
3877 in the server. Affected file silcd/protocol.c.
3879 * Removed the [RedirectClient] config section from the server
3880 configuration. Is not needed and I don't want to implement it.
3882 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Cleaned up the CMODE command in the server. It now works
3885 correctly and supports all the modes defined in the protocol.
3886 Affected file is silcd/command.c.
3888 * Added `hmac_name' field to the SilcChannelEntry in the server
3889 to hold the default HMAC of the channel. It can be set when
3890 creating the channel (with JOIN command). Affected files
3893 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3894 type to indicate the change of the current cipher and hmac
3895 on the channel. Client can safely ignore the <cipher> argument
3896 (if it chooses to do so) since the CHANNEL_KEY packet will
3897 force the channel key change anyway. The <hmac> argument is
3898 important since the client is responsible of setting the new
3899 HMAC and the hmac key into use.
3901 * Fixed the CMODE command in the client library as well.
3903 * Tested CMODE command in router environment successfully.
3905 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Show the version of the remote client (or server) when connecting
3908 to the server. It is logged to the log file. Affected file
3909 is silcd/protocol.c.
3911 * Fixed the KILLED notify handling in the client library. The
3912 client must be removed from all channels when receiving the
3915 Also, do not remove the client entry when giving the KILL
3916 command but when the KILLED notify is received.
3918 * Removed silc_idlist_find_client_by_nickname from the server.
3919 Not needed anymore. Affected files silcd/idlist.[ch].
3921 * Implemented the CHANNEL_CHANGE notify type handling to the
3922 server. Affected file silcd/server.c.
3926 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Added silc_server_send_notify_invite to send the INVITE
3929 notify between routers.
3931 * Implemented the INVITE command correctly to the server.
3933 * Implemented the INVITE notify type handling in the server.
3935 * Implemented the INVITE command to the client library and on the
3938 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Added function silc_server_get_client_resolve to find the
3941 client entry by ID from all ID lists and then resolve it
3942 (using WHOIS) if it cannot be found. Affected file is
3945 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Implemented the BAN command to the client library.
3949 * The JOIN command in the server now checks the invite list
3952 * Changed the silc_command_reply_payload_encode_va and the
3953 silc_command_payload_encode_va to support that if argument is
3954 NULL it ignores and checks the next argument. Affected file
3955 lib/silccore/silccommand.c.
3957 * Added silc_server_send_notify_ban to send the BAN notify
3958 type between routers.
3960 * Chaned the silc_notify_payload_encode to support that if
3961 argument is NULL it ignores and checks the next argument.
3962 Affected file lib/silccore/silcnotify.c.
3964 * Tested ban lists in router environment successfully.
3966 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Implemented BAN command to the server, in silcd/command.[ch].
3970 * Removed the BAN and INVITE_LIST modes from the CMODE command
3973 * Added function silc_string_match to regex match two strings.
3974 Affected files lib/silcutil/silcutil.[ch].
3976 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Redefined parts of the SilcChannelEntry in the server to support
3979 the new ban and invite lists.
3981 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Redefined the INVITE command. The same command can be used to
3984 invite individuals to the channel but also to manage the invite
3985 list of the channel (to add to and remove from the invite list).
3986 Updated the protocol specs.
3988 * Added new command SILC_COMMAND_BAN that can be used to manage
3989 the ban list of the channel. Updated the protocol specs.
3991 * Removed the channel modes: the SILC_CMODE_BAN and the
3992 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3993 in the CMODE command. The equivalent features are now available
3994 using INVITE and BAN commands. Updated the protocol specs.
3996 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3997 in the network about change in the current ban list. The notify
3998 type is not used by the client.
4000 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4001 support the invite lists.
4003 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added new function silc_string_regexify that converts string
4006 including wildcard characters into regex string that can
4007 be used by the GNU regex library. Added into the file
4008 lib/silcutil/silcutil.[ch].
4010 Added silc_string_regex_combine to combine to regex strings
4011 into one so that they can be used as one regex string by
4012 the GNU regex library. Added into the file
4013 lib/silcutil/silcutil.[ch].
4015 Added silc_string_regex_match to match two strings. It returns
4016 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4018 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Imported GNU regex to the soruce tree into lib/contrib.
4021 Fixed some compiler warning from the regex.c.
4023 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Fixed MOTD command in the server to work in router environment.
4027 * Fixed the MOTD command in the client library to support
4028 the server argument in the command.
4030 * Added `nickname_len' argument to the silc_idlist_add_client
4031 in the server, as the `nickname' argument may be binary data
4034 * Added silc_idlist_get_channels to return all channels from
4037 * Implemented LIST command to the server. Affected file is
4040 * Implemented the LIST command to the client library and on the
4043 * Added [<user count>] argument to the LIST command reply.
4044 With private channels the user count is not shown.
4046 * Updated TODO and README.
4048 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * The client entry's data.registered must be TRUE even with
4051 global client entry on global client list. The data.registered
4052 is used to check whether the client is anymore in the network,
4053 for example with WHOWAS command so it must be valid.
4055 * Fixed the WHOWAS command in the server. It now actually works
4056 in router environment. Added function into silcd/command_reply.c
4057 silc_server_command_reply_whowas_save.
4059 * Added silc_idlist_purge function to the silcd/idlist.c
4060 to periodically purge the ID Cache.
4062 * Fixed INFO command in the server. It works now in router
4063 environment. Added <server name> argument to the INFO command
4064 reply. Updated the protocol specs.
4066 * Fixed minor bug in silc_idcache_purge to not purge if the
4067 expire value is zero.
4069 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4070 they were buggy because of the WHOWAS information.
4072 * Fixed local command MSG to handle the async resolving of
4073 the remote client properly. It used to fail the first MSG.
4074 Affected file silc/local_command.c.
4076 * Added `data_len' field to SilcIDCache context.
4078 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Update TODO. Todo in commands in the server.
4082 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4085 used by routers as broadcast packet to inform other routers
4086 about the changed user mode.
4088 Implemented the notify handling in the server. Affected file is
4089 silcd/packet_receive.c. Added the function
4090 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4092 * Added new generic Channel Payload and deprecated the New Channel
4093 Payload. The New Channel Payload is now the generic Channel
4096 * Added new argument `mode' to the silc_server_send_new_channel
4097 as it is required in the Channel Payload now.
4099 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4100 and created a new and real SilChannelPayload to represent the
4101 new generic Channel Payload. Implemented the encode/decode
4102 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4104 * Added silc_server_get_client_channel_list to return the list
4105 of channels the client has joined for WHOIS command reply.
4106 Affected file silcd/server.[ch].
4108 * Implemented the channel list sending in the WHOIS command reply
4109 in server and in the client.
4111 Implemented the channel list displaying on the user interface
4112 as well. Affected file silc/client_ops.c.
4114 * Added silc_channel_payload_parse_list to parse list of Channel
4115 Payloads. It returns SilcDList list of SilcChannelPayloads.
4116 Client for example can use this function to parse the list of
4117 channels it receives in the WHOIS command reply. The caller
4118 must free the list by calling silc_channel_payload_list_free.
4119 Affected files lib/silccore/silcchannel.[ch].
4121 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Added one new argument <user mode> to the WHOIS command reply
4124 to return the mode of the user in SILC. Updated the protocol
4127 Implemented it to the server and client.
4129 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Fixed the mode printing on the user interface on joining.
4132 Affected file silc/client_ops.c.
4134 * Implemented the UMODE command and user modes in general to the
4135 client library and to the user interface.
4137 * Implemented the UMODE command to the server.
4139 * The server now sends UNKNOWN_COMMAND error status if client sends
4140 unknown command. Affected file silcd/command.c.
4142 * All server commands now handle the command identifier the right
4143 way when sending the command reply to the client. The client can
4144 use to identify the command replies with the identifier.
4146 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Added silc_server_get_client_route to resolve the route to
4149 the client indicated by the client ID. Affected file is
4152 * Added silc_server_relay_packet as general function to relay
4153 packet to arbitrary destination. This deprecates functions
4154 like _send_private_message_key, _relay_notify etc. Affected
4155 file is silcd/packet_send.[ch].
4157 Removed silc_server_send_key_agreement,
4158 silc_server_send_private_message_key and
4159 silc_server_packet_relay_notify functions from the file
4160 silcd/packet_send.[ch].
4164 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4165 server. Affected file silcd/packet_receive.[ch].
4167 * Implemented the KILL command to the client. Implemented the
4168 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4169 Affected files lib/silcclient/command[_reply].c and
4170 lib/silcclient/client_notify.c. Implemented the KILL notify
4171 printing in the user inteface.
4173 * Fixed a lot silc_parse_nick memory leaks from the client
4174 library in the file lib/silcclient/command.c.
4176 * Changed the silc_server_send_notify_on_channels's `sender'
4177 argument from SilcSocketConnection to SilcClientEntry to
4178 check the sender as entry and not as connection object and not
4179 to send to the client provided as argument. The affected file
4180 is silcd/packet_send.[ch].
4182 * The notify packets that are destined directly to the client used
4183 to not to be processed by the server. Now changed that and the
4184 server processes all notify packets. After relaying the packet
4185 to the client the notify packet is processed in the server.
4187 * The silc_server_free_client_data now checks whether there is
4188 pending outgoing traffic for the client and purges the data to
4189 the network before removing the client entry.
4191 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4194 an client is killed from the SILC Network. Updated the protocol
4197 Added new function silc_server_send_notify_killed to the
4198 silcd/packet_send.[ch].
4200 * Added function silc_server_packet_relay_notify to relay notify
4201 packets that are destined directly to a client. In this case
4202 the server does not process the notify packets but merely relays
4203 it to the client. Affected file silcd/packet_send.[ch].
4205 Added also silc_server_packet_process_relay_notify to check
4206 whereto relay the notify. Affected file is
4207 silcd/packet_receive.[ch].
4209 * Implemented the KILL command to the server.
4213 * Added the backup schema desgined last fall to the protocol
4214 specs for everyone to see. The specification is in the
4215 *-spec-xx.txt draft and the packet type definitions for the
4216 backup routers is in *-pp-xx.txt draft. Thusly, added also
4217 new packet type SILC_PACKET_CELL_ROUTERS.
4219 * A big security problem in the implementation discovered. The
4220 signoff of an client did not cause new channel key generation
4221 which it of course should've done. The channel keys must be
4222 always re-generated when client leaves (or signoffs) the channel.
4223 The silc_server_remove_from_channels funtion now handles
4224 the channel key re-generation.
4226 * Added `sender' argument to the silc_server_send_notify_on_channels
4227 to not to send the client provided as argument. Affected file
4228 silcd/packet_send.[ch].
4230 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Implemented OPER and SILCOPER commands into the server and
4235 * Added silc_auth_verify and silc_auth_verify_data to verify
4236 the authentication directly from the authentication payload.
4237 It supports verifying both passphrase and public key based
4238 authentication. Affected file lib/silccore/silcauth.[ch].
4240 * Added `hash' field to the SilcIDListData structure. It is the
4241 hash negotiated in the SKE protocol. Affected file is
4244 * Slight redesigning of the SilcAuthPayload handling routines.
4245 Do not send SilcPKCS but SilcPublicKey as argument.
4247 * Implemented the public key authentication support to the
4248 serverconfig. The public key is loaded from the provided path
4249 and saved as authentication data to void * pointer. Thus,
4250 changed the unsigned char *auth_data to void *auth_data;
4252 * Fixed SHUTDOWN command to send the reply before the server
4253 is shutdown. :) Affected file silcd/command.c.
4255 * Fixed fatal bug in CONNECT command. The hostname was invalid
4256 memory and server crashed. Affected file silcd/command.c.
4258 * Fixed fatal bug in CLOSE command. The server_entry became
4259 invalid but was referenced later in the command. Affected file
4262 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Fixed fatal bug in failure packet handling. Server ignored
4265 the failure and thus crashed when it came.
4269 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4272 that the command may be executed only once in (about) 2 seconds.
4273 The old SILC_CF_LAG flag is same but allows command bursts up
4274 to five before limiting.
4276 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4277 server code. Various commands now includes the CF_LAG_STRICT
4278 flag to disallow any kind of miss-use of the command.
4280 * Fixed the silc_buffer_unformat to not to allocate any data
4281 if the length of the data is zero. It used to allocate the
4282 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4284 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Changed the format of AdminConnection configuration section
4287 in the server. Added username of the admin to the format.
4288 Affected files silcd/serverconfig.[ch].
4290 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4291 to return admin configuration data by host, username and/or
4294 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Implemented WHOWAS command to the server. Added the functions:
4298 silc_server_command_whowas_parse,
4299 silc_server_command_whowas_send_reply,
4300 silc_server_command_whowas_from_client and
4301 silc_server_command_whowas_from_server
4303 * Added <Client ID> argument to the WHOWAS command reply. Updated
4304 the protocol specs accordingly.
4306 * Implemented WHOWAS command and command_reply to the client
4309 Implemented the WHOWAS printing on the user interface.
4311 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Added new argument to the WHOWAS command reply, the real name.
4314 It is an optional argument. Updated the protocol specs.
4316 * Added SilcIDCacheDestructor callback that is registered when
4317 the SilcIDCache is allocated. The callback is called when
4318 an cache entry in the ID Cache expires, or is purged from the
4319 cache. Added into lib/silccore/idcache.[ch].
4321 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4322 to destruct the client entries when the cache entry expires.
4323 Other ID Cache's in server and in the client library ignores
4326 * If the ID Cache entry's `expire' field is zero then the entry
4327 never expires. Added boolean `expire' argument to the
4328 silc_idcache_add function in the lib/silccore/idcache.[ch].
4329 If it is TRUE the default expiry value is used.
4331 * Added silc_server_free_client_data_timeout that is registered
4332 when client disconnects. By default for 5 minutes we preserve
4333 the client entry for history - for WHOWAS command.
4335 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Added support to the server to enforce that commands are not
4338 executed more than once in 2 seconds. If server receives
4339 commands from client more frequently, timeout is registered
4340 to process the commands. Affected file silcd/command.c.
4341 Added new function silc_server_command_process_timeout.
4343 * Changed NICK_NOTIFY handling in client library to check that
4344 if the client's nickname was changed, so there is no need to
4345 resolve anything from the server.
4347 * Removed error printing from the WHOIS and IDENTIFY commands.
4348 If error occurs then it is ignored silently in the client library.
4349 The application, however, may map the received error to
4350 human readable error string. The application currently maps
4351 the NO_SUCH_NICKNAME error to string.
4353 * Made the command status message public to the application. Moved
4354 them from lib/silcclient/command_reply.c to
4355 lib/silcclient/command_reply.h. The application can map the
4356 received command status to the string with the
4357 silc_client_command_status_message function.
4359 * Added check to the server to check that client's ID is same
4360 as the Source ID in the packet the client sent. They must
4363 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Added dist-bzip hook to the Makefile.am to make bzip2
4366 compressed distributions.
4368 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Server now enforces the maximum length for the nickname and
4371 the channel as protocol specification dictates. 128 bytes for
4372 nickname and 256 bytes for channel name.
4374 * Moved the WHOIS printing to the application. The client libary
4375 does not print out the WHOIS information anymore, the application
4376 must do it. Renamed silc_client_command_reply_whois_print to
4377 the silc_client_command_reply_whois_save.
4379 The client's idle time is also sent to the application now, and
4380 the idle is shown on screen.
4382 * Added silc_client_command_reply_identify_save to save the
4383 received IDENTIFY entries.
4385 * Do not check for channel private keys in message sending and
4386 reception if the channel does not have the PRIVKEY mode set.
4387 Affected file lib/silclient/client_channel.c.
4389 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4392 just surfaced after chaning the JOIN procedure.
4394 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Added silc_client_get_clients_by_list to get client entries
4397 from Client ID list, that is returned for example by JOIN
4398 and USERS command replies. The application should use this
4399 function for example when JOIN command reply is received to
4400 resolve the clients already on the channel (library does not
4401 do that anymore as USERS command reply is not used in the JOIN
4402 procedure anymore). Affected files lib/silcclient/silcapi.h and
4403 lib/silcclient/idlist.c.
4405 * JOIN command reply and USERS command reply returns now SilcBuffer
4406 pointers instead of unsigned char pointers when returning
4407 the client list and mode list.
4409 * Added <Client ID> argument to the JOIN command reply, mainly
4410 for the server to identify for which client the command was
4411 originally sent. Updated protocol specs accordingly.
4413 * Added SilcDlist private_key pointer to the SilcChannelEntry
4414 in the client to support the channel private keys. Affected
4415 file is lib/silcclient/idlist.h.
4417 * Added SilcChannelPrivateKey argument to the function
4418 silc_client_send_channel_message so that application can choose
4419 to use specific private ke if it wants to. If it is not provided,
4420 the normal channel key is used, unless private keys are set.
4421 In this case the first (key that was added first) is used
4422 as the encryption key.
4424 * Implemented the support for channel private key handling.
4425 Implemented the following functions:
4427 silc_client_add_channel_private_key,
4428 silc_client_del_channel_private_keys,
4429 silc_client_del_channel_private_key,
4430 silc_client_list_channel_private_keys and
4431 silc_client_free_channel_private_keys
4433 Affected file lib/silcclient/client_channel.c.
4435 * Added the support for the private keys in the channel message
4436 sending and encryption and in the message reception and
4437 decryption. Affected funtions are
4438 silc_client_send_channel_message and silc_client_channel_message.
4440 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Added SKE's key verify callback to the client library's
4443 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4445 * Removed the statement that server (or router) must send USERS
4446 command reply when joining to the channel so that the client
4447 knows who are on the channel. Instead, the client list and
4448 client's mode list is now sent in the JOIN command reply to the
4449 client who joined channel. This is better solution.
4451 * Added function silc_server_get_users_on_channel and function
4452 silc_server_save_users_on_channel to the silcd/server.[ch].
4454 * Removed function silc_server_command_send_users from the
4457 * Do not show topic on the client library anymore. The topic is
4458 sent in the command reply notify to the application and the
4459 application must show the topic now.
4461 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added client searching by nickname hash into the IDENTIFY and
4464 WHOIS commands in the server as they were clearly missing from
4465 them. Affected file is silcd/command.c.
4467 * Fixed a bug in private message receiving in the client library.
4468 The remote ID was freed and it wasn't supposed, now it is
4471 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Minor fix to the channel payload; allocate the data area, as it
4474 needs to be of specific length.
4476 * If the key agreement port is zero then the operating
4477 system will define the bound port. Affected files are
4478 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4480 * Added new function silc_channel_payload_decrypt into the file
4481 lib/silccore/silcchannel.[ch].
4483 * Moved the channel message etc, check from silc_packet_decrypt
4484 to applications. The library calls now a generic
4485 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4486 when the packet is either normal or special. This was done to
4487 allow more wide range of checking that was not allowed when
4488 the code was in library. Now applications can do virtually any
4489 checks to the packet and return to the library the decision how
4490 the packet should be processed. Affected files are
4491 lib/silccore/silcpacket.[ch].
4493 Added silc_server_packet_decrypt_check to the server and
4494 silc_client_packet_decrypt_check to the client library.
4496 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4497 to send with specified source and destination information.
4499 * Channel message delivery between routers was broken after the
4500 channel key distribution was fixed earlier. The channel key
4501 was used be to distributed to other routers as well which is not
4502 allowed by the protocol. Now this is fixed and channel keys
4503 really are cell specific and the channel message delivery between
4504 routers comply with the protocol specification.
4506 * Fixed various commands in server to check also the global list
4507 for the channel entry and not just the local list. The affected
4508 file silcd/command.c.
4510 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Added assert()s to buffer formatting and unformatting routines
4513 to assert (if --enable-debug) when error occurs. Affected
4514 file: lib/silcutil/silcbuffmt.c.
4516 * Changed to auto-reconnect to check whether the remote host is
4517 router and register the re-connect timeout if it is. It used
4518 to check that whether we are normal server, but router must do
4519 auto-reconnect with another router as well. Affected file
4522 * Removed the [<key len>] option from CMODE command as the cipher
4523 name decides the key length, nowadays. See the defined ciphers
4524 from the protocol specification.
4526 * Added [<hmac>] option to the CMODE command to define the HMAC
4527 for the channel. Added SILC_CMODE_HMAC channel mode.
4529 * Added [<hmac>] option for the JOIN command so that user can
4530 select which HMAC is used to compute the MACs of the channel
4533 * Added Hmac field to the Channel Message Payload. The integrity
4534 of plaintext channel messages are now protected by computing
4535 MAC of the message and attaching the MAC to the payload. The
4536 MAC is encrypted. Now, it is clear that this causes some
4537 overhead to the size of the packet but rationale for this is that
4538 now the receiver can verify whether the channel message decrypted
4539 correctly and also when private keys are set for the channel the
4540 receiver can decrypt the packet with several keys and check from
4541 the MAC which key decrypted the message correctly.
4543 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4544 lib/silccrypt/silccipher.[ch].
4546 * Added silc_hash_len to return the digest length into the
4547 lib/silcrypt/silchash.[ch].
4549 * Rewrote parts of Silc Channel Payload interface in the
4550 lib/silccore/silcchannel.[ch]. The encode function now also
4551 encrypts the packet and parse function decrypts it.
4553 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Fixed a minor formatting bug in the SKE's key material processing.
4556 It actually might have processed the keys wrong way resulting
4559 * Redefined the mandatory HMAC algorithms and added new algorithms.
4560 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4561 and hmac-md5 truncated to 96 bits. The mandatory is now
4562 hmac-sha1-96. Rest are optional (including the one that used
4563 to be mandatory). Rationale for this is that the truncated HMAC
4564 length is sufficient from security point of view and can actually
4565 make the attack against the HMAC harder. Also, the truncated
4566 HMAC causes less overhead to the packets. See the RFC2104 for
4569 * Added new [hmac] configuration section. The SKE used to use
4570 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4571 is of course wrong. The official names that must be proposed in
4572 the SKE are the ones defined in the protocol specification
4573 (hmac-sha1-96 for example). The user can configure any hmac
4574 using any hash function configured in the [hash] section. At
4575 least, the mandatory must be configured.
4577 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4579 * Added HMAC list to the SKE proposal list. It has now both
4580 hash algorithm list and HMAC list. This makes the protocol
4581 incompatible with previous versions. The SKE now seems to work
4582 the way it is supposed to work, for the first time actually.
4584 * Defined plain Hash algorithms to the protocol specification.
4587 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Implemented support for key agreement packets into the server.
4590 Added functions silc_server_key_agreement and
4591 silc_server_send_key_agreement. Other than these functions,
4592 server has nothing to do with this packet.
4594 * Added support for private message key packets into the server.
4595 Added functions silc_server_private_message_key and
4596 silc_server_send_private_message_key.
4600 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4601 called in the protocol's final callback instead in the END
4602 protocol state. This makes a little more sense and in the same
4603 time in client we can use the same protocol routines for normal
4604 key exchange and to key agreement packet handling as well.
4606 * Added to both client's and server's KE protocol context the
4607 SilcSKEKeyMaterial pointer to save the key material. We will
4608 bring the key material to the protocol's final callback by doing
4609 this. The final callback must free the key material.
4611 * Added SKE's packet_send callback into client's KE protocol
4612 context so that the caller can choose what packet sending function
4613 is used. This way we can use different packet sending when
4614 doing normal SKE when doing key agreement packet handling (in
4615 the key agreement packet handling we do not want to encrypt
4618 * Implemented the responder side of the key agreement routines
4619 in the client. The client can now bind to specified port and
4620 accept incoming key negotiation. The key material is passed
4621 to the application after the protocol is over.
4623 * Implemented the processing of incoming Key Agreement packet
4624 in the client. Added function silc_client_key_agreement to
4627 * Implemented the intiator side of the key agreement routines
4628 in the client. The client can now initiate key agreement with
4629 another remote client. The key material is passed to the
4630 application after the protocol is over.
4632 * Created client_keyagr.c to include all the key agreement
4635 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4636 SILC_TASK_CALLBACK except that it is not static.
4638 * Created client_notify.c and moved the Notify packet handling
4639 from the client.[ch] into that file.
4641 * Created client_prvmsg.c and moved all private message and
4642 private message key routines from the client.[ch] into that file.
4644 * Create client_channel.c and moved all channel message and
4645 channel private key routines from the client.[ch] into that file.
4647 * Changed silc_client_get_client_by_id_resolve to resolve with
4648 WHOIS command instead of IDENTIFY command, in the file
4649 lib/silclient/idlist.c.
4651 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4653 * Implemented the SKE's responder side to the Client library.
4655 * When FAILURE is received to the protocol do not trust it
4656 blindly. Register a timeout to wait whether the remote closes
4657 the connection as it should do it, only after that process the
4658 actual failure. This was changed to both client and server.
4660 * Added client_internal.h to include some of the structures
4661 there instead of client.h in lib/silcclient/.
4663 * Added function silc_task_unregister_by_callback to unregister
4664 timeouts by the callback function.
4666 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Some "Incomplete WHOIS info" errors has been appearing on the
4669 log files. Took away the entry->userinfo check from WHOIS
4670 reply sending. The entry->userinfo is now " " if client did not
4671 provide one. I thought this was fixed earlier but something
4672 is wrong still. Let's see if the error still appears.
4674 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Fixed a minor bug in the login when the channel key is
4677 re-generated in the server. It used to generate the key in
4678 wrong order and thus caused problems in the channel traffic.
4680 * Fixed a minor bug in channel key distsribution after
4681 KICK command. The key was not sent to the router even though
4684 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Added silc_ske_process_key_material_data as generic routine
4687 to process any key material as the SILC protocol dictates. The
4688 function is used by the actual SKE library but can be used by
4689 applications as well. This relates to the private message keys
4690 and the channel private keys since they must be processed the
4691 same way the normal SILC session keys. The protocol dictates
4692 this. Affected files: lib/silcske/silcske.[ch].
4694 Added also silc_ske_free_key_material to free the
4695 SilcSKEKeyMaterial structure.
4697 * Defined silc_cipher_set_key function to set the key for
4698 cipher without using the object's method function. The affected
4699 files: lib/silccrypt/silccipher.[ch].
4701 * Implemented silc silc_client_add_private_message_key,
4702 silc_client_add_private_message_key_ske,
4703 silc_client_del_private_message_key,
4704 silc_client_list_private_message_keys and
4705 silc_client_free_private_message_keys functions in the
4708 Added functions silc_client_send_private_message_key to send
4709 the Private Message Key payload and silc_client_private_message_key
4710 to handle incoming Private Message Key payload.
4712 * Added Cipher field to the Private Message Key payload to set
4713 the cipher to be used. If ignored, the default cipher defined
4714 in the SILC protocol (aes-256-cbc) is used.
4716 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Removed lib/silcclient/ops.h file.
4720 Redefined parts of the SILC Client Library API. Created new
4721 file silcapi.h that deprecates the ops.h file and defines the
4722 published Client Library API. Defined also private message key
4723 API and channel private key API into the file.
4725 This is the file that the application must include from the
4726 SILC Client Library. Other files need not be included by
4727 the application anymore.
4729 * Added new key_agreement client operation callback and also
4730 defined the Key Agreement library API for the application.
4732 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4735 is used by clients to request key negotiation between another
4736 client in the SILC network. If the negotiation is started it
4737 is performed using the SKE protocol. The result of the
4738 negotiation, the secret key material, can be used for example
4739 as private message key.
4741 Implemented the Key Agreement payload into the files
4742 lib/silccore/silauth.[ch].
4744 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Redefined ciphers for the SILC protocol. Added some new ciphers
4747 and defined the key lengths for the algorithms. Changed the
4748 code accordingly. The default key length is now 256 bits.
4750 * Fixed SKE key distribution function silc_ske_process_key_material
4751 when the key length is more than 128 bits. The default key
4752 length in SILC is now 256 bits.
4754 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4755 to indicate unsupported algorithm.
4757 * Renamed rijndael.c to aes.c and all functions as well.
4759 * Fixed a long standing channel key setting bug in client library.
4760 Weird that it has never surfaced before.
4762 * Fixed bug in channel deletion. If the entire channel is removed
4763 then it must also delete the references of the channel entry
4764 from the client's channel list as the client's channel entry and
4765 the channel's client entry share same memory.
4767 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Implemented CONNECT and SHUTDOWN commands in the client.
4771 * Implemented CLOSE command to the client.
4773 * Added the function silc_idlist_find_server_by_name into the
4774 files silcd/idlist.[ch].
4776 Added the function silc_idlist_find_server_by_conn into the
4777 files silcd/idlist.[ch].
4779 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * DIE command was renamed to SHUTDOWN. Updated the both code
4784 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4785 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4787 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4790 * Added function silc_server_create_connection function to create
4791 connection to remote router. My server implementation actually
4792 does not allow router to connect to normal server (it expects
4793 that normal server always initiates the connection to the router)
4794 so the CONNECT command is only good for connecting to another
4797 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4800 or some other client was kicked from the channel.
4802 Implemented the handling of the notify type to both client
4805 Implemented silc_server_send_notify_kicked to send the KICKED
4806 notify. It is used to send it to the server's primary router.
4808 * Implemented the KICK command into server and client.
4810 * Added `query' argument to the silc_idlist_get_client function
4811 to indicate whether to query the client from server or not if
4814 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4815 to indicate that the client is not channel founder.
4819 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Removed the rng context from SilcPacketContext structure and
4822 changed that the packet routine uses the Global RNG API.
4824 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Added support for quit message that client can "leave" on the
4827 channel when it quits the SILC. It is ditributed inside the
4828 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4830 Added silc_server_free_client_data that will take the
4831 signoff message as argument.
4833 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4835 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Updated parts of the protocol specification to keep it up
4840 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4843 payloads in one packet.
4845 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4846 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4847 use now the new List flag.
4849 * Also deprecated the following packet types: REPLACE_ID,
4850 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4852 * Added list support for Notify packet in server.
4854 * Added silc_server_send_notify_channel_change to send the
4855 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4856 the silc_server_send_replace_id.
4858 * Added silc_server_send_notify_nick_change to send the
4859 NICK_CHANGE notify type. Deprecates the function
4860 silc_server_send_replace_id.
4862 * Added silc_server_send_notify_join to send the JOIN notify type.
4863 Deprecates the function silc_server_send_new_channel_user.
4865 * Added silc_server_send_notify_leave to send LEAVE notify type.
4866 Deprecates the function silc_server_send_remove_channel_user.
4868 * Added silc_server_send_notify_cmode and
4869 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4870 types. Deprecates the silc_server_send_set_mode function.
4872 * Added SERVER_SIGNOFF notify type to indicate that server has
4873 quit. This means that all clients on the channel from that
4874 server will drop. This can be also used when netsplit happens.
4876 Deprecated REMOVE_ID packet type since it is not needed anymore
4879 Added silc_server_send_notify_server_signoff to send the
4880 SERVER_SIGNOFF notify type. Deprecates the function
4881 silc_server_send_remove_id.
4883 Added also silc_server_send_notify_signoff to send the
4884 SIGNOFF notify type.
4886 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4887 SILC protocol from this day on. Changed the protocol
4888 specification as well.
4890 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4891 notify type. It is used between routers to notify about
4892 topic changes on a channel.
4894 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4897 * Partly updated the protocol specification to comply with the
4898 changes now made. It is still though a bit outdated.
4900 * The JOIN notify type now takes one extra argument <Channel ID>.
4901 The packet used to be destined to the channel but now the
4902 JOIN type may be sent as list thus it is impossible to
4903 destine it to any specific channel. By adding this argument
4904 it is again possible.
4906 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Added CREDITS file. The CHANGES and CREDITS file will appear
4909 in the distribution as well.
4911 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4914 types in the server's silcd/packet_receive.c.
4916 * Implemented CMODE and CUMODE to work in router environment.
4918 * Fixed minor encoding and decoding buglet from the
4919 lib/silccore/silcmode.c.
4921 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4924 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4926 * Changed all SilcConfigServer* and silc_config_server* to
4927 SilcServerConfig* and silc_server_config*, respectively.
4930 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Associated the ID (client or server ID) to the Authentication
4933 Payload to avoid any possibility of forging. Updated the
4934 protocol specification and the code accordingly.
4936 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * The RSA key length is now save to the RsaKey context in the
4939 key generation process in lib/silccrypt/rsa.c. The key length
4940 is now used to figure out the maximum size of the block allowed
4941 to be encrypted/signed.
4943 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4944 is equivalent to the silc_mp_mp2bin but does not allocate any
4947 * Changed silc_mp_mp2bin API to take length argument. If it is
4948 non-zero then the buffer is allocated that large. If zero, then
4949 the size is approximated using silc_mp_sizeinbase, which however
4952 * Created Global RNG API which is global RNG that application can
4953 initialize. After initializing, any routine anywhere in the
4954 code (including library) can use RNG without allocating a new
4955 RNG object. This was done to allow this sort of use of the
4956 RNG in code that has no chance to allocate RNG object. All
4957 applications currently allocate this and many routines in the
4958 library use this. Affected file lib/silccrypt/silcrng.[ch].
4960 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4961 it to use the Global RNG API.
4963 * Defined Authentication Payload into protocol specification that
4964 is used during SILC session to authenticate entities. It is
4965 used for example by client to authenticate itself to the server
4966 to obtain server operator privileges.
4968 Implemented this payload into the lib/silccore/silcauth.[ch].
4969 Implemented also routines for public key based authentication
4970 as the new protocol specification dictates.
4972 Moved definitions of different authentication methods from
4973 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4975 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4976 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4977 silc_pkcs_verify_with_hash functions into the file
4978 lib/silccrypt/silcpkcs.[ch].
4980 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * The client entry's userinfo pointer must be always valid.
4983 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4984 will fail since it requires the userinfo. Now, the userinfo
4985 is allocated as "" if actual userinfo does not exist. Actually,
4986 it must exist and it is totally Ok to drop client connections
4987 that does not announce the userinfo. However, we will make
4988 this workaround for now.
4990 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4991 to return the remote port by socket.
4993 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4996 SILC_SERVER_PENDING_EXEC and added an new macro
4997 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4998 data or when error occurs while processing the pending command.
5000 Added new argument `destructor' into silc_server_command_pending
5001 and to the SilcServerCommandPending object. This destructor is
5002 now called after calling the pending callback or if error occurs
5003 immediately. If error occurs the actual pending callback won't
5004 be called at all - only the destructor. The destructor may be
5005 NULL if destructor is not needed.
5007 All this applies for client library code as well. Similar
5008 changes were made there as well for the pending commands.
5010 In the client, the application must now allocate the
5011 SilcClientCommandContext with the silc_client_command_alloc
5014 * Added reference counter to the SilcServerCommandContext. Added
5015 function silc_server_command_alloc and silc_server_command_dup
5018 Same type of functions added to the client library for the same
5021 * Removed the cmd_ident from IDListData away since it is now
5022 global for all connections. It is the command identifier used
5023 in command sending and with pending commands. The affected file
5026 * Added reference counter to the SilcSocketConnection objecet to
5027 indicate the usage count of the object. The object won't be
5028 freed untill the reference counter hits zero. Currently only
5029 server uses this, and client ignores it. The client must be
5030 set to use this too later. The affected files are
5031 lib/silccore/silcsockconn.[ch]. Added also the function
5032 silc_socket_dup to increase the reference counter.
5034 This was mainly added because it is possible that the socket
5035 is removed underneath of pending command or other async
5036 operation. Now it won't be free'd and proper DISCONNECTING
5037 flags, etc. can be set to avoid sending data to connection that
5038 is not valid anymore.
5040 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5041 the connection. After that it sets SILC_SET_DISCONNECTED.
5042 It is, however, possible that the socket data is not still freed.
5043 The silc_server_packet_process now checks that data is not
5044 read or written to connection that is DISCONNECTED. The socket
5045 get's freed when the reference counter hits zero.
5047 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Changed the client operation API: channel_message operation's
5050 `sender' is now the client entry of the sender, not the nickname
5051 and the `channel' is the channel entry, not the channel name.
5053 In the private_message operation the `sender' is now also the
5054 client entry of the sender not the nickname.
5056 Affected file is lib/silcclient/ops.h and all applications
5057 using the client operations.
5059 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Moved the calling of ops->connect() from connect_to_server_final
5062 into receive_new_id functin since that is the point when the
5063 client is actually allowed to send traffic to network. The
5064 affected file is lib/silcclient/client.c.
5066 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5069 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5070 (if needs broadcasting) instead of broadcasting the packets one
5071 by one which would make a burst in the network traffic.
5073 * Added `broadcast' argument to the functions in silcd/server.[ch]
5074 silc_server_create_new_channel[_with_id] to indicate whether
5075 to send New Channel packet to primary router.
5077 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Added new function into the silcd/server.[ch] files:
5080 silc_server_create_new_channel_with_id to create new channel with
5081 already existing Channel ID.
5083 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5084 lib/silccore/silcpacket.h. This packet is used t send list of
5085 Set Mode payloads inside one packet. Server uses this to set
5086 the modes for the channels and clients on those channels, that it
5087 announced to the router when it connected to it. The protocol
5088 specification has been updated accordingly.
5090 * The silc_server_new_channel did not handle the packet coming
5091 from normal server as it normally does not send that. However,
5092 when it announces its channels it does send it. Implemented
5093 the support for that.
5095 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5096 into the file lib/silccore/id.h.
5098 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Fixed memory leaks in the functions silc_idlist_del_client,
5101 silc_idlist_del_channel and silc_idlist_del_server in the file
5102 silcd/idlist.c. All of those leaked like a sieve.
5104 * Fixed some small memory leaks in the client's function
5105 silc_client_notify_by_server.
5107 * Added functions into silcd/server.c: silc_server_announce_clients,
5108 silc_server_announce_channels and silc_server_announce_server.
5109 These functions are used by normal and router server to announce
5110 to its primary router about clients, channels and servers (when
5111 router) that we own. This is done after we've connected to the
5114 These functions effectively implements the following packet types:
5115 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5116 and SILC_PACKET_NEW_ID_LIST.
5118 * Added new functions into the silcd/packet_receive.[ch]:
5119 silc_server_new_id_list, silc_server_new_channel_list and
5120 silc_server_new_channel_user_list to handle the incoming
5121 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5123 * Added support of changing Channel ID in the function
5124 silc_server_replace_id. If the server that announces a channel
5125 to the router already exists in the router (with same name but
5126 with different Channel ID), router is responsible to send
5127 Replace ID packet to the server and force the server to change
5128 the Channel ID to the one router has.
5130 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5131 client that the Channel ID has been changed by the router. The
5132 normal server sends this to the client. Client must start using
5133 the new Channel ID as the channel's ID.
5135 Implemented handling of this new type into lib/silcclient/client.c
5136 into the function silc_client_notify_by_server.
5138 * Added new function silc_idlist_replace_channel_id into the files
5139 silcd/idlist.[ch] to replace the Channel ID.
5141 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Call silc_server_command_identify_check always when processing
5144 the IDENTIFY command in silcd/command.c
5146 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5149 send keepalive packets. The packet can be sent by clients,
5150 servers and routers.
5152 Added function silc_socket_set_heartbeat into the file
5153 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5154 If not set, the heartbeat is not performed. The actual
5155 heartbeat is implemented in the low level socket connection
5156 library. However, application is responsible of actually
5159 Added silc_server_send_heartbeat to send the actual heartbeat
5160 packet into silcd/packet_send.[ch]. Server now performs
5161 keepalive with all connections.
5163 * Added silc_task_get_first function into lib/silcutil/silctask.c
5164 to return the timeout task with shortest timeout. There was a bug
5165 in task unregistration that caused problems. TODO has been
5166 updated to include that task system must be rewritten.
5168 * The client library will now resolve the client information when
5169 receiving JOIN notify from server for client that we know but
5170 have incomplete information.
5172 * Rewrote parts of silc_server_remove_from_channels and
5173 silc_server_remove_from_one_channel as they did not remove the
5174 channel in some circumstances even though they should've.
5176 * Encryption problem encountered in server:
5178 The LEAVE command used to send the Channel Key packet to the
5179 router immediately after generating it. However, the code
5180 had earlier sent Remove Channel user packet but not immediately,
5181 ie. it was put to queue. The order of packets in the router
5182 was that Channel Key packet was first and Remove Channel User
5183 packet was second, even though they were encrypted in the
5184 reverse order. For this reason, MAC check failed. Now, this
5185 is fixed by not sending the Channel Key packet immediately but
5186 putting it to queue. However, this is more fundamental problem:
5187 packets that are in queue should actually not be encrypted
5188 because packets that are sent immediately gets encrypted
5189 actually with wrong IV (and thus MAC check fails). So, packets
5190 that are in queue should be encrypted when they are sent to
5191 the wire and not when they put to the queue.
5193 However, the problem is that the current system has not been
5194 designed to work that way. Instead, the packet is encrypted
5195 as soon as possible and left to the queue. The queue is then
5196 just purged into wire. There won't be any fixes for this
5197 any time soon. So, the current semantic for packet sending
5200 o If you send packet to remote host and do not force the send
5201 (the packet will be in queue) then all subsequent packets to the
5202 same remote host must also be put to the queue. Only after the
5203 queue has been purged is it safe again to force the packet
5206 o If you send all packets immediately then it safe to send
5207 any of subsequent packets through the queue, however, after
5208 the first packet is put to queue then any subsequent packets
5209 must also be put to the queue.
5211 Follow these rules and everything works fine.
5213 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Added new function silc_server_remove_clients_by_server to
5216 remove all client entries from ID list when the server connection
5217 is lost. In this case it is also important to invalidate all
5218 client entires as they hold the invalid server entry. This
5219 fixes fatal bug when server has lost connection and will reconnect
5222 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Made some sanity checks to silc_server_daemonise like to check
5225 whether the requested user and group actually exists.
5227 * Added sanity check to SKE's silc_ske_responder_finish to check
5228 that the public and private key actually is valid.
5230 * Invalidate the client's nickname when receiving Replace ID
5231 packet and the Client ID is being replaced. This means that the
5232 server will query the nickname if someone needs it (client)
5235 * Sort the ID Cache in client library when the ID Cache data
5236 has changed (needs sorting).
5238 * Do not allow for SILC client to create several connections to
5239 several servers. The client does not support windows right now
5240 and generating multiple connections causes weird behaviour.
5242 Irssi-silc client does support windows and can handle several
5243 connections without problems, see: www.irssi.org and SILC plugin.
5245 * Fixed some places where client was added to the IDList. The
5246 rule of thumb is following (in order to get everything right):
5247 If the client is directly connected local client then the
5248 `connection' argument must be set and `router' argument must be
5249 NULL to silc_idlist_add_client function. If the client is not
5250 directly connected client then the `router' argument must
5251 bet set and the `connection' argument must be NULL to the
5252 silc_idlist_add_client function.
5254 * The funtion silc_server_packet_send_local_channel actually did
5255 not check whether the client was locally connected or not. It
5256 does that now. Fixed a bug related to LEAVE command.
5258 * Fixed Remove Channel User payload parsing bug in server's
5259 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5261 * The server's silc_server_save_channel_key now checks also the
5262 global ID list for the channel as it might not be in the local
5263 list. Fixed a bug related to LEAVE command.
5265 * Is this the end of the [<unknown>] buglet that has been lurking
5266 around for a long time? A little for loop fix in server's
5267 silc_server_command_whois_parse that is used by both IDENTIFY
5268 and WHOIS command. At least, this was a clear bug and a cause
5269 of one type of [<unknown>] buglet.
5271 * WHOIS and IDENTIFY commands call the function
5272 silc_server_command_[whois/identify]_check function even if
5273 we are not router server.
5275 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Added --with-gmp configuration option. If set the GMP
5278 is always compiled in the SILC source tree. If not set then
5279 it is checked whether the system has the GMP3 installed. If
5280 it has then the GMP won't be compiled (the system's headers
5281 and library is used), if it doesn't have it then the GMP is
5282 compiled in the SILC source tree.
5284 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Changed RSA private exponent generation to what PKCS #1
5287 suggests. We try to find the smallest possible d by doing
5288 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5289 not security fix but optimization.
5291 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Added new config entry [Identity] to fork the server and run
5294 it as specific user and group. A patch from Bostik.
5296 * Imported Dotconf configuration library into lib/dotconf.
5297 This will be used to create the SILC configuration files later.
5298 It will appear in the distsribution after this commit.
5300 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * A big code auditing weekend happening. Auditing code for
5303 obvious mistakes, bugs and errors. Also, removing any code
5306 Removed files for being obsolete:
5308 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5309 inline in the file lib/silcutil/silcbuffer.h)
5311 o lib/silcutil/silcbufutil.c (the header has inline versions)
5313 Changed code to fix possible error conditions:
5315 o The buffer formatting routines now check that the destination
5316 buffer really has enough space to add the data. This applies for
5317 both buffer formatting and unformatting
5318 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5319 unformatting was changed to accomodate following rules:
5320 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5321 sent to the function while XXX_*STRING will not allocate or copy
5322 the data into the buffer. Instead it sets the pointer from the
5323 buffer into the pointer sent as argument (XXX_*STRING used to
5324 require that the pointer must be allocated already). This change
5325 makes this whole thing a bit more consistent and more optimized
5326 (note that the data returned in the unformatting with XXX_*STRING
5327 must not be freed now). The routines return now -1 on error.
5329 o Tried to find all code that use buffer_format and buffer_unformat
5330 and added return value checking to prevent formatting and
5331 especially unformatting errors and possible subsequent fatal
5334 o Changed ske->x and ske->KEY to mallocated pointers in
5335 lib/silcske/silcske.h. Fixed possible data and memory leak.
5337 o Added return value checking to all *_parse* functions. Fixed
5338 many memory leaks as well.
5340 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5341 so that buffer overflows would not happen. All code now also
5342 checks the return value as it can fail.
5344 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added reconnection support to server if the normal server looses
5347 its connection to the router (for example if router is rebooted).
5348 The server performs normal reconnection strategy implemented
5349 to the server. Affected file silcd/server.c.
5351 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Added new packet type SILC_PACKET_SET_MODE that is used to
5354 distribute the information about changed modes (for clients,
5355 channels and clients channel modes) to all routers in the
5356 network. Updated the protocol specification accordingly.
5358 Added functions into silcd/packet_send.c and
5359 silcd/packet_receive.c: silc_server_send_set_mode,
5360 silc_server_set_mode.
5362 Added new files silcmode.[ch] into lib/silccore that implements
5363 the encoding and decoding of Set Mode Payload. Added new type
5364 SilcSetModePayload. Moved the definitions of different modes
5365 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5367 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Oops, a little mistake in server's connection authentication
5370 protocol. The protocol is not ended with FAILURE but with
5371 SUCCESS if the authentication is Ok. :) Affected file is
5374 * Implemented NICK_CHANGE notify handling in server in the file
5375 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5376 the local clients on the channel. After the changing nickname
5377 in router environment snhould work and the [<unknown>] nickname
5378 should appear no more.
5380 The silc_server_replace_id function that receives the Replace ID
5381 payload now sends the NICK_CHANGE notify type also in the file
5382 silcd/packet_receive.c
5384 * Changed WHOIS and IDENTIFY command to support the maximum amount
5385 of arguments defined in protocol specs (3328 arguments). This
5386 fixed a bug that caused problems when there were more than three
5389 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Added extra parameter, command identifier, to the
5392 silc_client_send_command so that explicit command identifier
5395 Changed that ID list routines uses specific command identifier
5396 when sending WHOIS/IDENTIFY requests to the server so that they
5397 can be identified when the reply comes back.
5399 Affected files lib/silcclient/command.[ch],
5400 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5402 * Added `sender' argument to silc_server_packet_send_to_channel
5403 to indicaet the sender who originally sent the packet to us
5404 that we are now re-sending. Ignored if NULL. Affected file
5405 silcd/packet_send.[ch].
5407 * Added some server statistics support in silcd/server_internal.h
5408 SilcServerStatistics structure and around the server code. Also
5409 send some nice statistics information when client is connecting
5412 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Fixed channel ID decoding in server's JOIN command reply in
5415 silcd/command_reply.c
5417 * Fixed braodcasting of replace ID payload to not to send it if
5418 we are standalone server in silcd/packet_receive.c.
5420 * Fixed all channel message sending routines to not to send
5421 packets to clients that has router set, since they are routed
5422 separately in the same function earlier. Affects file
5423 silcd/packet_send.c and all channel packet sending functions.
5425 * In USERS reply, res_argv[i] are not allocated, the table
5426 is allocated. Thus changed that free the table, not its
5429 * In server's whois_check and identify_check if the client is
5430 locally connected do not send any WHOIS commands - they are not
5433 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Fixed some minor bugs in client when sending WHOIS command. The
5436 arguments was in wrong order.
5438 * Removed statis function add_to_channel from server in
5439 silcd/command.c that was previously used with the joining but
5442 * Tested USERS command in router environment successfully with two
5443 routers, two servers and two clients.
5445 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Reorganized the USERS command and command reply in client library
5448 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5449 When the command is given by user we register a pending command
5450 callback that will reprocess the command after the reply has been
5451 received from the server. When reprocessing the packet we then
5452 display the information. Thus, the USERS information is displayed
5453 now in the command callback instead of in the command reply
5454 callback. The processing of the command is same as previously
5455 when server has sent the command reply in the JOINing process.
5457 * Added to USERS command in silcd/command_reply.c to join the client,
5458 we didn't use to know about, to the channel after we've created
5459 a client entry for it. Also, for clienet we did know already still
5460 check whether it is on the channel or not and add it if not.
5462 * Removed silc_server_command_join_notify as the function and its
5465 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Changed the client's pending command handling to the same as the
5468 server's pending command handling. It is also now possible to
5469 execute command reply functions from other command reply
5470 function as the function callbacks for commands and command
5471 replies are one and same. The pending commands are not static
5472 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5473 in client connection context. Thus, pending commands are server
5474 connection specific as it is convenient.
5476 Changed the function silc_client_command_pending and
5477 silc_client_command_pending_del and added new function
5478 silc_client_command_pending_check. Removed the
5479 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5482 * Added cmd_ident, current command identifier, to the client
5483 connection context in lib/silcclient/client.h to keep track on
5484 command identifiers used in command sending. Client's command reply
5485 function handling now supports the mandatory command identifiers.
5487 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5488 funtions in client to fully support pending command callbacks.
5490 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5491 as one of the arguments to the application in the command reply
5494 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5495 before first releasing SILC but came back. Now it is removed again
5496 and should come back nomore. The FORWARDED flag was used only
5497 by the JOINing procedure by forwarding the command packet to router.
5498 Now, the JOINing procedure has been changed to more generic (due
5499 to various router environment issues) and FORWARDED is not needed
5500 anymore for anything. The protocol specification is yet to be
5503 Now, removed silc_server_packet_forward from server and the flag
5504 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5506 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Renamed NAMES command to USERS command. The NAMES was named that
5509 due to historical reasons. Now it is renamed. Also, rewrote
5510 parts of the USERS command. The nickname list is not sent anymore
5511 by the server. Only Client ID and mode lists are sent in the USERS
5512 command. Changed this also to the protocol specification.
5514 The client now resolves the names and stuff after it receives
5515 the USERS list from the server when joining to the channel.
5517 * WHOIS and IDENTIFY commands has been changed to support multiple
5518 Client ID's per command. One can now search for multiple users
5519 in the network by sending only one WHOIS or IDENTIFY command.
5520 Changed the code and the protocol specifications.
5522 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5523 uses silc_server_command_whois_parse to parse the request. */
5525 * If normal server, do not parse the WHOIS and IDENTIFY requests
5526 before sending it to the router. Saves some time.
5528 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Fixed JOIN command on client library. Wrong number of arguments
5531 used to crash the client.
5533 * Added silc_server_channel_has_global function to check whether
5534 channel has global users or not.
5536 * Added silc_server_channel_has_local function to check whether channel
5537 has locally connected clients on the channel.
5539 * The silc_server_remove_from_one_channel now checks whether the
5540 channel has global users or not after given client was removed from
5541 the channel. It also checks whether the channel has local clients
5542 on the channel anymore. If it does not have then the channel entry
5543 is removed as it is not needed anymore.
5545 * The silc_server_notify now checks on JOIN notify whether the joining
5546 client is one of locally connected or global. If it is global then
5547 the channel has now global users on the channel and that is marked
5548 to the channel entry. Also, it now saves the global client to
5549 global list who is joining and JOINs it to the channel. This is
5550 for normal server, that is.
5552 Changed silc_server_send_notify_on_channel,
5553 silc_server_packet_relay_to_channel and
5554 silc_server_packet_send_to_channel check if we are normal server
5555 and client has router set (ie. global client) do not send the
5556 message to that client, as it is already routed to our router.
5558 * Implemented LEAVE notify type handling in silc_server_notify
5561 * Tested LEAVE command in router environment successfully. Tested
5562 with two routers, two servers and two clients.
5566 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5568 * Implemented SIGNOFF notify type handling in silc_server_notify
5571 * silc_server_remove_id now removes the client entry from all channels
5572 it has joined and thusly sends SIGNOFF notify type.
5574 * Rewrote the NAMES list generation in server by removing two excess
5575 loops. The lists are created now inside one loop.
5577 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * silc_server_remove_channel_user checks now also global list
5580 for channel and client.
5582 * silc_server_new_channel_user checks now both local and global
5583 list for channel and client. Fixed a bug in client id decoding.
5584 Used to decode wrong buffer.
5586 * silc_server_channel_message checks now both local and global
5587 list for channel entry.
5589 * Tested channel joining (hence JOIN) in router environment
5590 successfully. Tested with two routers, two servers and two
5593 * Tested channel message sending in router environment successfully.
5595 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Added silc_server_save_channel_key into server.[ch] to save the
5598 received channel key in Channel Key payload processing. It is
5599 also used in JOIN command reply handling.
5601 Equivalent function silc_client_save_channel_key added into
5602 client.[ch] into client library.
5604 * Changed JOIN command reply to send information whether the channel
5605 was created or not (is existing already) and the channel key
5606 payload. Changed protocol specs accordingly.
5608 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5609 the request was sent by ID and not by nickname. Crashed on
5612 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5615 now correctly save the received data.
5617 * silc_server_free_sock_user_data now notifies routers in the
5618 network about entities leaving the network.
5620 At the same time implemented functions silc_server_remove_id
5621 and silc_server_send_remove_id to receive and send REMOVE_ID
5622 packets. The packet is used to notify routers in the network
5623 about leaving entities. The ID removed will become invalid in
5626 * Added function silc_idlist_del_server into server. Removes and
5627 free's server entry from ID list.
5629 * silc_server_private_message function now checks, if we are router,
5630 that the destination ID really is valid ID, naturally.
5632 * In router when NEW_ID packet is received (for new client) the
5633 hash of the Client ID is saved in the ID Cache but the
5634 client->nickname is set to NULL, instead of putting the hash
5637 IDENTIFY command now also checks that client->nickname must be
5638 valid. If it is not if will request the data from the server who
5639 owns the client. Added new function
5640 silc_server_command_identify_check.
5642 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5643 to set the command to already allocated Command Payload.
5645 * Tested private message sending in router environment with two
5646 routers, two servers and two clients. Fixed minor bugs and now
5649 * Fixed segfault from client's NAMES command. Used to crash if
5652 * Forwarded packets must not be routed even if it is not destined
5653 to the receiver. Changed server code comply with this.
5655 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Added `require_reverse_mapping' boolean value to ServerParams
5658 structure. If TRUE (not default) the server will require that
5659 the connecting host has fully qualified domain name.
5661 If the reverse mapping is not required and hostname could not be
5662 found the IP address is used as hostname.
5664 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Implemented version string checking to both client and server.
5667 The check is incomplete currently due to the abnormal version
5668 strings used in development version of SILC.
5670 * Changed all command functions in server to use the new
5673 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Changed char *data to unsigned char *data in ID Cache system to
5676 support binary data as ID Cache data. Changed code to support
5677 binary data in lib/silccore/idcache.c.
5679 * Renamed silc_server_packet_relay_command_reply to
5680 silc_server_command_reply as it is normal packet receiving
5681 function. Rewrote the function to accept command replys for
5682 servers and not only for clients.
5684 * Mark remote router always as registered server if we are connecting
5685 to it. Otherwise, commands sent by the router to us are ignored.
5687 * All ID List find routines now returns the ID Cache Entry pointer
5688 as well if requested.
5690 * WHOIS command works now in router environment, tested with two
5691 routers, two servers and two clients.
5693 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5694 in router environment (as it is almost equivalent to WHOIS) but
5695 hasn't been tested thoroughly. Added new functions:
5697 silc_server_command_identify_parse
5698 silc_server_command_identify_send_reply
5699 silc_server_command_identify_from_client
5700 silc_server_command_identify_from_server
5702 * Disabled route cache adding because adding two different ID's with
5703 same IP replaces the old cache entry thus giving wrong route.
5704 The entry->router->connection is always the fastest route anyway
5705 so route cache may not be needed. Of course, new routes maybe
5706 established after receiving the ID when the entry->router->connection
5707 might not be anymore the most optimal.
5709 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Add route cache for received ID for fast routing.
5713 * Added silc_server_packet_route to route received packet on router
5714 that is not destined to us.
5716 * Renamed silc_server_get_route to silc_server_route_get.
5718 * Added id_string and id_string_len fields into SilcServer to
5719 include encoded ServerID for fast comparing without excess
5720 encoding of the ID's.
5722 * Cleaned up WHOIS command on server side. Added following static
5725 silc_server_command_whois_parse
5726 silc_server_command_whois_check
5727 silc_server_command_whois_send_reply
5728 silc_server_command_whois_from_client
5729 silc_server_command_whois_from_server
5731 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5732 arguments in command replies. All command functions should be
5733 updated to use this macro.
5735 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Minor typo fixes on command reply handling on server.
5739 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Added silc_server_command_add_to_channel internal routine to add
5742 the client to the channel after router has created the channel and
5743 sent command reply to the server.
5745 * Added generic silc_server_send_command to send any command from
5748 * Use static buffer with ID rendering instead of duplicating data.
5750 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * Fixed a channel user mode bug when joining to a channel server gave
5753 everybody channel founder rights, oops.
5755 * We mark ourselves as the router of the incoming server connection
5756 if we are router ourselves. This way we can check in some packet
5757 sending functions whether it is locally connected server. For
5758 incoming router connections we put NULL.
5760 * For router sending packets locally means now always sending the
5761 packet cell wide; to local clients and local servers. For normal
5762 server sending packet locally means sending it to only local
5765 * Fixed the JOIN command to really work in router environment. If the
5766 channel is created it is always created by the router. Router is
5767 also responsible of making the initial joining to the channel,
5768 sending JOIN notify to the sending server and distributing
5769 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5770 does not exist server doesn't do anything else but forward the
5771 command to the router which performs everything.
5773 * Added silc_server_send_channel_key function to send the Channel Key
5776 * Added silc_server_create_channel_key to create new channel key. The
5777 channel key is now re-generated everytime someone joins or leaves
5778 a channel, as protocol dictates. Note: channel->key_len is the
5781 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5784 packet_receive.[ch] to separate packet sending and receiving
5785 routines. The server.[ch] now includes everything else including
5786 actual packet processing (writing and reading data) and other
5789 Renamed silc_server_private_message_send_internal to
5790 silc_server_send_private_message. The routine is still though
5791 used only to relay private messages as server does not send
5792 private messages itself.
5794 Renamed silc_server_new_channel to silc_server_create_new_channel
5795 and added new function sicl_server_new_channel that handles the
5796 incoming New Channel packet. Added also new sending function
5797 silc_server_send_new_channel to send New Channel Payload.
5799 * Added new function silc_server_notify to process incoming notify
5800 packet to the server/router. Server may then relay the notify
5801 to clients if needed.
5803 * Added new function silc_server_new_channel_user to process incoming
5804 New Channel User packet. Router will redistribute the packet and
5805 send JOIN notify to its local clients and locally connected servers
5806 if needed. Normal server will send JOIN notify to its local client
5807 on same channel when received this packet. Added also corresponding
5808 sending function silc_server_send_new_channel_user to sent the
5811 * Added boolean route argument to send_notif_to_channel and
5812 packet_send_to_channel functions to attempt to route the packet
5813 if it is TRUE and send only locally if it is FALSE.
5815 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * silc_server_replace_id now broadcasts the received replace ID
5818 packet if it is not broadcast packet already. The router must
5819 broadcast to inform other routers about changed ID.
5821 * Added backpointer to server's router into SilcServer context in
5822 silcd/server_internal.h.
5824 * Fixed silc_server_packet_broadcast to send correct broadcast
5827 * The channel key is now distributed to the local client as soon
5828 as it is received from the router (in router environment) so that
5829 no other packet may be sent for the channel until client has
5832 * silc_server_remove_channel_user now broadcasts the received
5833 Remove Channel User packet if it is not broadcast packet already.
5834 The router must broadcast to inform other routers about removed
5837 * Added users field into SilcPacketContext that is a reference count
5838 of the context. One can increase the reference count by calling
5839 silc_packet_context_dup which is now changed to just increase the
5840 reference count instead of duplicating the data. The reference
5841 count is decresed by calling silc_packet_context_free that will
5842 free the data after the reference count hits zero.
5844 For now on the packet context and everything allocated into it
5845 (including the raw packet from network) must be freed by calling
5846 the new silc_packet_context_free function. Added also new function
5847 silc_packet_context_alloc that must be used now to allocate the
5848 context. This also means that if a routine is asynchronous from
5849 silc_[client/server]_packet_parse_type the packet context must
5850 be duplicated by calling silc_packet_context_dup. Otherwise it
5851 gets free'd after silc_[client/server]_packet_parse_type returns.
5852 Also, one must remember that if packet is duplicated then its
5853 reference count must be decresed by calling the free function as
5854 many times as it was duplicated.
5856 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5857 from both client and server.
5859 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Made joining to a channel working in router environment.
5863 * Cleaned up JOIN command on server side and create function
5864 silc_server_command_join_channel internal routine to make the
5867 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5869 * Changed silc_command_pending list to SilcDList. Also, added
5870 `ident' field to SilcServerCommandPending structure to identify
5871 the reply and to call correct callback.
5873 Added silc_server_command_pending_check function to replace the
5874 corresnponding macro. The silc_command_pending list is not
5877 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5878 to set identifier to previously allocated Command Payload. It
5879 is used to set identifier for command when resending Command
5882 * Added silc_command_payload_encode_payload to encode Command
5883 Payload buffer from SilcCommandPayload structure.
5885 * Added silc_argument_payload_encode_payload to encode Argument
5886 payload buffer from SilcArgumentPayload structure.
5888 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Changed WHOIS command to support router connection on server side.
5891 The whois request is always sent to router unless the server is
5892 standalone server. After server has received the reply from the
5893 router will it send the reply to the client.
5895 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5896 broadcast received broadcast packet. The function is used only
5897 by router. The broadcast packet is always sent to the router's
5900 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5901 render given ID to printable string, for log files for example.
5903 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Made basic router to router connections working. At least they
5906 can now connect to each other but nothing really works the way
5907 they are supposed - yet.
5909 * Added new initiator token to RouterConnection configuration
5910 file in silcd/serverconfig.[ch]. It is used to tell whether we
5911 are the initiator to the remote router or whether we'll expect
5912 the other end to connect.
5914 * Moved registering of listener task to silc_server_init, hence
5915 the server starts listenning as soon as it is run, even if it
5916 does not have connections to other routers. Let's see how well
5919 * Changed default connection retry timeouts for more suitable in
5922 * Removed cipher and such arguments from silc_idlist_add_client
5923 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5924 Added new function silc_idlist_add_data to add the keys and stuff
5927 * Added SilcIDListData structure and added it to SilcClientEntry
5928 and SilcServerEntry as their first field in the structure. This
5929 way we can explicitly cast the ID entries to the SilcIDListData
5930 structure and get common data for the entries. In past, we had
5931 to first check what type of connection it is and then cast it to
5932 correct ID entry type. Now, we can directly cast the opaque
5933 pointer to the SilcIDListData (no matter what ID entry it actually
5934 is) and get the data needed.
5936 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5939 in some circumstances even if threre were timeout tasks, though not
5940 IO tasks, but tasks anyway. Now fixed.
5942 * Defined SilcServerConnection structure to hold connection specific
5943 stuff about directly connected servers and routers. The definition
5944 is currently in silcd/server_internal.h. I thought about having
5945 a bit more important role fro this struct but for now it is used
5946 only when connecting to other server (or router actually).
5948 * Added connecting retry support in server when connecting to
5949 router(s). The retry feature implement exponential backoff
5950 algorithm. Also, added SilcServerParams structure to hold default
5951 parameters for server. For now, it include these retry settings
5952 and are hard coded. After server is moded to be as Silc Server
5953 Library this structure will be more important.
5955 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Changed client librarys channel->clients table to SilcList and
5958 changed code accordingly.
5960 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Changed client's channel table to SilcList and changed code
5963 accordingly. Also changed SilcChannelClientEntry to include back-
5964 pointer to the channel so that client entry can use that structure
5965 as list as well and we have fast cross-reference to the channel.
5966 This change dramatically decreased the complexity of channel
5967 handling with client entry and vice versa (removed one extra
5968 loop when searching for channel entry from many functions).
5970 * Changed server->sim from table to SilcDList and changed code
5973 * NAMES command can now be used from user interface. It will show
5974 the user list on the channel, neatly.
5976 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5977 Code now saves realname of the user if it becomes available.
5979 * Renamed configure.in to configure.in.pre and made ./prepare
5980 script to automatically add correct version string to
5981 configure.in which it creates from configure.in.pre.
5983 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * NAMES command reply now shows users mode with the nickname when
5988 * Moved silc_client_ch[u]mode[_char] functions from
5989 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5990 place sucks, they are utility functions and should be in some
5993 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5995 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5998 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Added TRQ (efficient deque and list library) into lib/trq. This is
6003 a very good list library that is currently used in the SILC. Defined
6004 SilcList API over the library because I didn't like the API very
6005 much. See lib/trq/silclist.h for the API and examples of how to
6006 use the API. Fixed various places in the code to use the new
6007 SilcList API. The SilcList is meant for lists that has a structure
6008 already defined as a list. It is not suitable to add just some
6009 context to the list (in TRQ, the context is the list actually).
6011 So, I defined SilcDList that can be used for the purpose where
6012 predefined list structure does not exit. This can be used as
6013 such list. Now some context just can be added to the SilcDList.
6014 Currently this list is not used in the SILC just yet, though there
6015 are a lot places where this can replace dynamically allocated
6016 tables and I will fix these places, later, to use SilcDList.
6017 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6018 and use TRQ internally).
6020 Also fixed some annoying warning messages that the original TRQ
6021 code generated. Also minor changes to TRQ's Makefile.in.
6023 * Added support for querying by Client ID to both WHOIS and
6024 IDENTIFY commands into server, as required by the protocol.
6026 * Removed method function pointers from SilcBuffer structure. They
6027 weren't used to anything and just increased the context size for
6028 no good reason. This change also made silc_buffer_alloc and
6029 silc_buffer_free functions inline functions.
6031 * Disabled command flooding detection support until it's fixed so
6032 that it accepts commands in but does not execute them more than once
6035 * Added silc_net_localhost(), to return local hostname, into
6036 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6037 that must be initialized before calling silc_client_init.
6039 * Added new function: silc_server_send_notify_on_channels to send
6040 notify messages to all channels client has joined. It is assured
6041 that the message is sent only once per client.
6043 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6044 lib/silcutil/silcutil.[ch] as silc_format function. The new
6045 function is generic and is used by server as well, not only by
6046 the logging routines.
6048 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6049 the provided version string was not acceptable. Added new function:
6050 silc_ske_check_version into lib/silcske/silcske.h. The function
6051 must be implemented by the application (client or server) and it
6052 does not reside in the SKE library. The function checks the version
6053 string remote end sent.
6055 * Added back pointers (to opaque context and to SilcSocketConnection)
6056 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6058 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6059 duplicate packet context structure.
6061 * Changed `notify' client operation to send same arguments as client
6062 receives from server except for ID's. ID's are mapped to correct
6063 ID entry and that is returned. Also, if channel entry is not sent
6064 by server but the notify is for channel the channel entry is sent
6065 to application (otherwise application doesn't know that it is for
6066 channel (library gets it from packet's Destination ID)).
6068 * Added silc_client_remove_from_channels into client library to
6069 remove a client from all channels it has joined to. Used when
6070 received SIGNOFF notify from server. Added also new function
6071 silc_client_replace_from_channels to replace old ID entry with
6072 new ID entry on all channels. Used when received NICK_CHANGE
6075 * Fixed ID Cache list handling in silc_idlist_get_client in
6076 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6077 to get (or query) client by ID.
6079 * Updated TODO list.
6081 * Added connection authentication status message defined by the
6082 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6083 support for these into the code in client and server side.
6085 * Added generic function silc_client_send_command to send any command
6086 with variable argument list. Application should use this function
6087 to send commands if the command functions provided by the library
6088 does not suite for the application's user interface needs.
6090 * Added new `failure' client operation. Application is notified about
6091 received failure packet if client is executing a protocol. In this
6092 case the protocol's execution has failed.
6094 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6095 is required by the protocol.
6097 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6098 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6101 * Added status flag to SilcSKE object to indicate realtime status
6102 of the SKE protocol.
6104 * Application receives now exactly same command reply arguments as
6105 the library receives from server. However, if ID is received the
6106 corresponding ID entry is returned to the application (eg. Client
6107 ID is mapped to correct SilcClientEntry entry and that is returned).
6108 Changed command_reply client operation due to this change.
6110 * Changed all ID's in commands and in command replys as ID Payloads.
6111 Change affected both client and server side codes.
6113 All ID's sent in SILC network (with execption of ID's in SILC
6114 Packet header) are sent in ID Payload to support variable length
6117 * Server now notifies nick changes and notifies all clients on
6118 the channels about the new nickname (about the new Client ID,
6121 * Implemented CMODE command to change channel modes. Supports all
6122 channel modes defined by the protocol specs except ban and invite
6123 lists. (Also, private channel key mode is supported but support for
6124 setting private channel key in client is missing, thus, this mode
6125 has no effect on client side (except that server requires that the
6126 client uses private channel key and normal channel traffic does not
6129 Also, invite mode works per se, but INVITE command does not work
6130 yet correctly, so you can set channel as invite only channel but
6131 inviting clients to the channel does not work (it is yet to be
6132 thought what's the best way to do it).
6134 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6135 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6136 Implemented CUMODE command to change user's mode on the channel.
6137 Supports all modes defined by the protocol specs.
6139 * Added NAMES command reply to return users modes on the channel.
6141 * Removed unnecessary and slow ciphers from lib/silccrypt.
6143 * Set SO_KEEPALIVE option to connection sockets by default.
6145 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6147 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6148 redefined the Notify Payload into protocol specs.
6150 * Added silc_id_payload_parse_id to get ID directly from raw
6153 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6156 accept searching by Client ID as well.
6158 * Added support for LEAVE and SIGNOFF notify types in client library.
6160 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6161 to parse ID Payload from raw data.
6163 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Added flags parameter into silc_ske_assemble_security_properties
6166 function in lib/silcske/silcske.[ch].
6168 * Changed notify client operation to fit better for notify messages
6169 sent by server. The notify payload received from server is now
6170 passed to the application (after parsing it to SilcNotifyPayload).
6171 It is application's responsibility to retrieve the arguments
6172 from the payload and show the message the way it wants. The message
6173 sent by server is implementation specific.
6175 * Changed public keys to comply with the protocol specification.
6176 Old public keys are not supported anymore and are not compatible.
6178 * Removed nickname from Channel Payload as the latest draft removed
6179 it. The client must resolve the nickname from the NAMES command
6180 reply received when it joined the channel.
6182 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6184 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * Fixed some errors in protocol specification drafts.
6188 * Created lib/silccore/silcnotify.c to implement Notify Payload
6189 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6190 generic payloads described by protocol specifications. The file
6191 includes implementations for ID Payload and Argument Payload.
6193 * Changed Command Payload implementation to use the new Argument
6194 Payload. Changed command_xxxx_payload to command_payload_xxxx
6195 to comply with SILC coding conventions.
6197 * Added suppport for Argument Payload handling in Notify Payload
6198 implementation as protocol requires it. Added the new support
6199 into server and client lib as well.
6201 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Added support for multiple nicknames on same channel. [n] is
6204 added locally to the nickname if there are more than one same
6205 nicknames on the channel.
6207 * Server now sends all nicknames that matched WHOIS request.
6208 Client also shows the list received from server.
6210 * Added TOPIC command to client side. User can now set and show
6211 current topic on channel.
6213 * Added MOTD command to client and server. Also, server sends the
6214 motd when client connects to the server.
6216 * Changed version strings to comply ISO 8601.
6218 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6220 * Fixed protocol error handling in client library. It should now
6221 cope even if the SKE fails for some reason.
6223 * Made new protocol specification drafts for submitting to IETF.
6225 * Implemented TOPIC command to server in silcd/command.c.
6227 * Added two new notify types into lib/silccore/silcnotify.h:
6228 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6229 notify nickname change and topic setting/change on a channel.
6231 * API change of command_reply operation in client library. The
6232 application gets now the status type received from server as well.
6234 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6238 * Cras fixed and optimized the packet handling even further and
6239 it should work now. Minor change to the prototype of function
6240 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6242 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Added new function into lib/silcutil/silcschedule.[ch]:
6245 silc_schedule_with_fd to select() a specified fd. The function
6246 returns after timeout expires or data arrives or goes. The
6247 function is used by packet routines to wait that all data is
6248 received from network.
6250 * Fixed data reading from network in lib/silccore/silcpacket.c.
6251 The code now assures that all data is read from the fd and then
6252 continues packet processing. This was a bug fix since the code
6253 used to drop some data in some circumstances.
6255 * Added new function into lib/silcclient/client.[ch]:
6256 silc_client_start_key_exchange to start key exchange after
6257 connection has been established to server. The code internally
6258 now uses this funtion but its main purpose was to provide it
6259 for applications that perform their own connecting. After
6260 application has created a connection it merely calls this
6261 function to start the key exchange between client and server.
6262 The library takes care of everything else after that.
6264 Updated also lib/silcclient/README to explain the usage of
6267 * Do not send to application information that connection has
6268 been established. Application gets notified it by connect
6271 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Applied cras's patch to add silc_schedule_one function. The
6274 function runs scheduler once and returns.
6276 * Fixed the scheduler after cras messed it up. The timeout
6277 handling works now as it's supposed to work.
6279 * Added into lib/silccore/ silcnotify.h to include notify
6280 message types support. Changed silc_server_send_notify*
6281 functions, in server.[ch], to support those new notify types.
6282 Added the support for the notify types into client library,
6283 as well. Added new notify client operation into ops.h in
6286 * Changed silc_server_packet_send_to_channel to send normal
6287 packets instead of just channel message packets. The function
6288 is now used to send the notify packets to channels. It is not
6289 used to send channel message packets anymore, as server never
6292 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6293 va_arg()s as it seems to require it nowadays. I guess, if SILC
6294 is compiled with older va_arg() the new code should work anyway.
6296 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Splitted core library. Core library (lib/silccore) includes
6299 now only SILC protocol specific core (and common) components.
6300 Created new utility library (lib/silcutil) that includes more
6301 generic purpose stuff. The stuff for util library was taken
6302 from the old core library. This was minor and easy split.
6304 * Created SILC Client Library (lib/silcclient) that includes
6305 implementation of the SILC client without user interface. This
6306 was major move from silc/ directory. The code has been changed
6307 so that it is transparent towards the user interface. The
6308 silc/ directory includes now the same user interface as before
6309 and it uses the new client library. Read lib/silcclient/README.
6310 Basicly, the client library performs everything else related
6311 to SILC except user interface handling. Also, configuration
6312 files are considered to be part of user interface and library
6313 does not handle them.
6315 This change also changed a lot of structures, function naming etc.
6316 Most important change was that SilcClientWindow object was
6317 renamed to SilcClientConnection in the client library. Created
6318 also new file lib/silcclient/ops.h. Also added new files
6319 silc/local_command.[ch] and silc/client_ops.[ch].
6321 All these changes were made to make it easier for user interface
6322 designers to create what ever user interface for the SILC client
6325 It is also expected that the server will be moved to lib
6326 directory as well and SILC Server Library will be created;
6327 sometimes in the future.
6329 * Removed Local commands from lib/silccore/silccommand.h as
6330 they are application specific and new client library does not
6331 handle any of those anymore.
6333 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6334 old client implementation in silc/.
6336 * Added support for callback functions in SILC_LOG_* macros.
6337 Application can now set its own callbacks that will be called
6338 instead of using the default functions that will always print
6339 the debug messages to stderr (or stdout). Also, debugging can
6340 now be disabled by setting silc_debug to FALSE and re-enabled by
6341 setting it to TRUE. Note, that logging will still work even
6342 if debugging is disabled.
6344 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6345 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6346 silc_log_reset_debug_callbacks.
6348 * To enable debugging in silc client one must give now -d
6349 option on command line.
6351 * Changed silc_schedule_init to automatically allocate task queues
6352 if they are not allocated before calling it.
6354 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * Added GMP 3.1 into math library.
6358 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6361 a channel in SILC network. The packet is used by servers and
6362 routers to notify other routers that user has left a channel.
6363 This little feature was missing until now. Added the feature
6364 to protocol specification as well.
6366 Added functions: silc_server_send_remove_channel_user and
6367 silc_server_remove_channel_user into server.[ch].
6369 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6370 lib/silccore/silcpacket.h. However, they are not implemented
6373 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * Fixed joining to a channel and sending channel messages
6376 between server and router. The channel message sending should
6377 now work inside a cell.
6379 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6381 * Fixed the private message sending between server and router.
6382 The private message sending should now work inside a cell.
6384 * Added silc_server_replace_id into server.[ch] to replace
6385 existing ID in the SILC network.
6387 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6388 and silc_idlist_replace_server_id into idlist.[ch] in server.
6390 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Fixed the server to server connections. Server can again now
6393 connect to router. Router to router connections probably does
6396 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6398 * Added dynamic protocol registering support. Now protocols can
6399 registered and unregistered on the fly. Patch by cras.
6401 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added lib/contrib directory to hold routines that some platforms
6404 don't have but are needed by SILC.
6406 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6407 into lin/contrib to provide getopt() and getopt_long() for
6408 those who don't have it.
6410 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Added AWAY command to client. When away message is set and
6413 client receives a private message packet the client automatically
6414 replies to the sender with the away message.
6416 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6417 bug seemed to be the cause of recent problems when compiling
6420 * Added version detection support to SKE protocol specification
6421 and added the new changes to the SKE implementation as well.
6422 There were other minor changes in the SKE protocol as well.
6424 Many changes in lib/silcske/silcske.[ch] and in
6425 lib/silcske/payload.[ch].
6427 * Added ^U functionality, clear input line. Patch from cras.
6429 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Mainly small bugfixes on core library. Fixed some debugging
6432 logging and buffer overflow in silclog.c.
6434 * Updated config.sub and config.guess on the distribution tree.
6436 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Added command lagging support in server. Client may execute
6439 commands now only once in two seconds.
6441 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Optimized packet reception. MAC computation and checking is now
6444 also more optimized. A lot previously duplicated code is now
6445 used as generic by both client and server.
6447 * Fixed key pair generation in clientutil.c
6449 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Added into lib/silccore/silcbufutil.[ch] new function;
6452 silc_buffer_realloc.
6454 * Moved generic packet sending/encryption functions to
6455 lib/silccore/silcpacket.[ch] from client and server. Some
6456 rewriting of the functions.
6458 * Moved all generic packet reception/decryption functions to
6459 lib/silccore/silcpacket.[ch] from client and server. The
6460 packet processing is now much cleaner in both client and server.
6461 These were major changes in both client and server.
6463 * Created many common functions in server to do packet sending.
6464 Previously code were duplicated a lot, this has been removed
6467 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Rewrote major parts of the ID cache system. Don't know
6470 whether it is better now or not but at least the API is more
6473 * Major rewrite on ID cache stuff on client because of the ID
6474 cache API changes. Added idlist.c to client.
6476 * Also major rewrite on ID cache stuff on server as well.
6477 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6478 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6479 in hand, instead they are all put into the ID cache system now.
6480 All server_idlist_* routines uses ID cache now instead of
6481 traversing its own lists (those lists does not exist anymore).
6482 SilcIDList though still exists. Also, SilcXXXEntry's are

6487 * Finally made the SKE implementation compliant to the protocol
6488 specification. All mp integers are now binary encoded as
6489 opposed being HEX encoded.
6491 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6494 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6495 functions: silc_[encode/decode]_pem. Also added function
6496 silc_encode_pem_file to PEM encode with newlines ('\n') for
6499 * SILC public keys are now encoded either PEM or binary. Same
6500 option is for private keys as well. By default private keys
6501 are binary encoded and public keys PEM encoded. Silly HEX
6502 encoding were removed.
6504 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6505 function to create fingerprints.
6507 * Fixed a bug in SHA1; does not change the original data anymore.
6509 * Partly implemented INFO command on client and server side.
6510 Fixed CLEAR command. Changes to SERVER command; show current
6511 server(s) when giving command without arguments. Added
6512 VERSION command to client.
6514 * Added check to server that unregistered connections cannot
6515 execute commands (unless it is specificly allowed).
6517 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Fixed screen refresh.
6521 * Fixed channel joining bug from client. On some circumstances
6522 client tried to join to a channel it had already joined.
6524 * Added public key verification process into client's protocol.c.
6525 The client now verifies the public key from user and saves
6526 it into ~./silc/serverkeys/ directory.
6528 Added into: clientutil.[ch]: silc_client_verify_server_key.
6530 * Changed SKE protocol's silc_ske_initiator_finish function
6531 to accept callback function that verifies the received public
6532 key. Removed old silc_ske_verify_public_key function.
6534 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6537 silc_pkcs_private_key[_data]_set.
6539 * Made the password and public authentication more cleaner in
6540 server's protocol.c.
6542 * Removed historic and obsolete protocol `channel_auth' from
6543 both client and server.
6545 * Removed wrong way of sending command status messages from
6546 server to client in server's command.c. The old way violated
6547 protocol specification.
6549 Changes to silccore/silccommand.[ch]: removed
6550 silc_command_encode_status_payload -> not needed anymore,
6551 changed silc_command_encode_payload_va to accept extra
6552 argument on variable argument list. The argument type must
6553 now be provided to the function. Also, added new function:
6554 silc_command_encode_reply_payload_va which is same as
6555 normal command_encode_payload_va except command status type
6556 is provided as extra argument.
6558 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6560 * Added ~./silc directory handling. The directory includes the
6561 public and private keys for the client.
6563 Added silc_client_check_silc_dir, silc_client_create_identifier
6564 and silc_client_load_keys.
6566 * Implemented SILC protocol compliant public key. Added public
6567 and private key saving to and loading from files.
6569 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6570 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6571 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6572 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6573 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6575 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6576 silc_pkcs_load_[public/private]_key.
6578 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Added silc_server_get_route (route.[ch]) to get connection
6581 data for the fastest route for given ID.
6583 * Implemented INVITE command on client and server. The command
6584 were re-defined in the SILC Protocol Specification and the
6585 implementation now complies with the specification.
6587 * Implemented PING command on client and server.
6589 * Implemented NAMES command on client and server. The server side
6590 supports currently only normal server not router server yet.
6591 Some changes to NAMES definition in SILC protocol specification.
6593 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Implemented LEAVE command on client and server.
6597 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6598 again. This change was made to the protocol as well. Server
6599 should not violate the protocol specification anymore.
6601 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6604 was tested. SOCKS4 was not but should work anyway.
