87 lib/silcsftp ****DONE****
90 o Porting to use the new util library. (***DONE)
95 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
96 ============================
98 o Implement silc_packet_engine_stop and silc_packet_stream_destroy.
100 o Implement ACK packet and packet payload.
102 o SilcPacketEngine. (***DONE)
104 o New SILC Packet API. (***DONE)
107 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
108 ============================
110 o IV Included flag support, UDP transport support (***TESTING NEEDED)
112 o SILC_PACKET_FLAG_ACK support.
115 lib/silccore/silcid.[ch] ****DONE****
116 ========================
118 o Add silc_id_str2id to accept the destination buffer as argument
119 and thus not require any memory allocation. Same will happen
120 with silc_id_payload_* functions. (***DONE)
122 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
128 o All payload encoding routines should take SilcStack as argument.
130 o All payload test routines into lib/silccore/tests/.
136 o Removing key from the repository is not possible currently. It should
140 lib/silcske/silcske.[ch] ****DONE****
141 ========================
143 o IV Included flag support in SKE (***DONE)
145 o UDP transport changes; retransmission support by using exponential
146 backoff algorithm. (***DONE)
148 o SilcConnAuth header file documentation. (***DONE)
151 lib/silccrypt ****PARTLY DONE****
154 o Implement SILC Public Key Version 2 handling in sign/verify. Implement
155 Version (V) identifier (***DONE)
157 o Add fingerprint to SilcSILCPublicKey and retrieval to silcpk.h.
159 o Implement PKCS #1 sign/verify with hash OID. (***TESTING NEEDED)
161 o Implement the defined SilcDH API. The definition is in
162 lib/silccrypt/silcdh.h.
164 o SSH2 public keys support, allowing the use of SSH2 public keys in
167 o OpenPGP certificate support, allowing the use of PGP public keys
170 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
171 Move the SILC Public Key routines away from the crypto library into
172 the core library (silccore). silc_pkcs_public/private_key_* routines
173 to silc_public/private_key_* routines. The silc_public_key_* routines
174 should also automatically handle SILC Public Keys, and other keys
175 and certificates as well. Add fe. silcpk.h into silccore. It should
176 also include the Public Key Payload encoding and decoding routines.
181 o Assembler AES (***DONE)
186 lib/silcutil ****PARTLY DONE****
189 o The regex code from lib/contrib might compile fine on all platforms.
190 No need to make it silcutil/unix/ specific. Add them to generic
193 o Fix universal time decoding (doesn't accept all forms) in silctime.c.
195 o silc_stringprep to non-allocating version.
197 o Compression routines are missing. The protocol supports packet
198 compression thus it must be implemented. SILC Zip API must be
201 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
202 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
205 o bool -> SilcBool (***DONE)
207 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
209 lib/silcutil/silcbuffer.h ****DONE****
210 =========================
212 o Remove the `truelen' field from SilcBuffer as it is entirely
213 redundant since we can get the true length of the buffer by
214 doing buffer->end - buffer->header. Add silc_buffer_truelen
215 macro instead. Consider also removing `len' field too since
216 it effectively is buffer->tail - buffer->data, and adding
217 silc_buffer_len macro can do the same. These would save
218 totally 8 bytes of memory per buffer. (***DONE)
221 lib/silcutil/silcbuffmt.[ch] ****DONE****
222 ============================
224 o SilcStack aware silc_buffer_unformat (***DONE)
226 o SilcStack aware silc_buffer_format (***DONE)
228 o silc_buffer_format reallocates automatically (***DONE)
230 o SILC_STR_OFFSET (***DONE)
233 lib/silcutil/silcstack.[ch] ****DONE****
234 ===========================
236 o Data stack implementation (***DONE)
239 lib/silcutil/silcstream.[ch] ****DONE****
240 ============================
242 o Add abstract SilcStream. (***DONE)
245 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
246 ==================================
248 o Add SilcSocketStream (***DONE)
250 o Add SilcSocketStream for WIN32
252 o Handle EOS sending to upper layer properly
254 o Test QoS after the changes made to socket stream
257 lib/silcutil/silcschedule*.[ch] ****PARTLY DONE****
258 ===============================
260 o Scheduler can be optimized for FD tasks by changing the fd_queue
261 to SilcHashTable instead of using linked list. We need to do
262 one-to-one mapping of FD to task and hash table is more efficient
265 Also redefine the silc_select to perhaps return a separate
266 structure of the events that actually occurred, instead of
267 returning the events in the fd_list which is then traversed
268 in the generic code to find the changed events. This can be
269 made faster by having own struct which includes only the
270 changed events, thus the tarversing is faster since the whole
271 fd_list is not traversed anymore (it is still traversed in the
272 silc_select but at least it removes one extra tarversing later
275 Other task queues should be changed to use SilcList. (***DONE)
277 o Add SILC scheduler's internal routines into a table of implementation
278 function pointers, that the generic code then takes as extern from
279 implementation. These are the silc_schedule_internal_* routines.
282 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
283 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
285 o SILC Schedule API changes to WIN32.
288 lib/silcutil/silcasync.[ch] ****DONE****
289 ===========================
291 o Add SilcAsyncOperation to utility library. Any function that takes
292 callback as an argument must/should return SilcAsyncOperation.
296 lib/silcutil/silctime.[ch] ****DONE****
297 ===========================
299 o SilcTime. (***DONE)
301 o system time, universal, generalized. (***DONE)
304 lib/silcutil/silcfsm.[ch] ****DONE****
305 =========================
307 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
310 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
311 ===============================================
313 o Add UDP interface (***DONE)
315 o Add UDP interface for WIN32
317 o New network interfaces (***DONE)
323 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
324 client and client library, but TMA in server, due to the significantly
325 increased memory consumption with TFM, and the rare need for public
326 key operations in server.
328 o Change LTM and TFM function names when importing to SILC tree to avoid
329 rare linking problems on system that has same named symbols already in
332 o The SILC MP API function must start returning indication of success
333 and failure of the operation.
335 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
336 any other MP function (including utility ones) that may allocate
341 o All utility functions should be made non-allocating ones.
344 lib/silcutil/symbian/ ****PARTLY DONE****
345 =====================
347 o lib/silcutil/symbian routines missing or not completed.
350 o Something needs to be thought to the logging globals as well,
351 like silc_debug etc. They won't work on EPOC. Perhaps logging
352 and debugging is to be disabled on EPOC.
355 lib/silcasn1 ****PARTLY DONE****
358 o ASN.1 library (***DONE)
360 o Header documentation missing. (***DONE)
362 o Some string encodings missing (copy/paste matter). (***DONE)
364 o Negative integer encoding
370 o PKIX implementation
376 o (Re)write commands/command replys.
378 o (Re)write notify handling.
380 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
381 cause sending of multiple SIGNOFF notify's instead of the one
382 SERVER_SIGNOFF notify that the server received. This should be
383 optimized so that the only SERVER_SIGNOFF is sent and not
384 SIGNOFF of notify at all (using SIGNOFF takes the idea about
385 SERVER_SIGNOFF away entirely).
387 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
388 sent to a client if it is on same channel as the client that
389 signoffed. However, the entire SERVER_SIGNOFF list is sent to
390 the client, ie. it may receive clients that was not on the
391 same channel. This is actually against the specs. It must be
392 done per channel. It shouldn't receive the whole list just
393 because one client happened to be on same channel.
395 o MAYBE: The SilcChannelClientEntry can be:
399 where address is SilcClientEntry address XOR SilcChannelEntry.
400 You can get SilcClientEntry by doing client = chl->address XOR channel,
401 and SilcChannelEntry by doing channel = chl->address XOR client.
402 As long as the other pointer is always available when accessing the
403 structure this can be done.
405 o Add reference counters to all Silc*Entry structures
407 o SERVICEs support (plugin, SIM)
409 o If client's public key is saved in the server (and doing public key
410 authentication) then the hostname and the username information could
411 be taken from the public key. Should be a configuration option!
413 o Add a timeout to handling incoming JOIN commands. It should be
414 enforced that JOIN command is executed only once in a second or two
415 seconds. Now it is possible to accept n incoming JOIN commands
416 and process them without any timeouts. THis must be employed because
417 each JOIN command will create and distribute the new channel key
418 to everybody on the channel (Fix this to 0.9.x).
420 o Related to above. If multiple JOINs are received in sequence perhaps
421 new key should be created only once, if the JOINs are handeled at the same
422 time. Now we create multiple keys and never end up using them because
423 many JOINs are processed at the same time in sequence. Only the last
424 key ends up being used.
426 o The CMODE cipher & hmac change problem (#101).
