107 o All packet waiting timeout tests and error condition tests.
110 lib/silcsftp ****DONE****
113 o Porting to use the new util library. (***DONE)
118 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
119 ============================
121 o Implement silc_packet_engine_stop and silc_packet_stream_destroy.
123 o Implement ACK packet and packet payload.
125 o SilcPacketEngine. (***DONE)
127 o New SILC Packet API. (***DONE)
130 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
131 ============================
133 o IV Included flag support, UDP transport support (***TESTING NEEDED)
135 o SILC_PACKET_FLAG_ACK support.
138 lib/silccore/silcid.[ch] ****DONE****
139 ========================
141 o Add silc_id_str2id to accept the destination buffer as argument
142 and thus not require any memory allocation. Same will happen
143 with silc_id_payload_* functions. (***DONE)
145 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
151 o Removing key from the repository is not possible currently. It should
154 o Add fingerprint as search constraint.
157 lib/silcske/silcske.[ch] ***PARTLY DONE****
158 ========================
160 o Ratelimit to UDP/IP transport for incoming packets.
162 o IV Included flag support in SKE (***DONE)
164 o UDP transport changes; retransmission support by using exponential
165 backoff algorithm. (***DONE)
167 o SilcConnAuth header file documentation. (***DONE)
170 lib/silccrypt ****PARTLY DONE****
173 o Implement SILC Public Key Version 2 handling in sign/verify. Implement
174 Version (V) identifier (***DONE)
176 o Add fingerprint to SilcSILCPublicKey and retrieval to silcpk.h.
178 o Implement PKCS #1 sign/verify with hash OID. (***TESTING NEEDED)
180 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
181 Move the SILC Public Key routines away from the crypto library into
182 the core library (silccore). silc_pkcs_public/private_key_* routines
183 to silc_public/private_key_* routines. The silc_public_key_* routines
184 should also automatically handle SILC Public Keys, and other keys
185 and certificates as well. Add fe. silcpk.h into silccore. It should
186 also include the Public Key Payload encoding and decoding routines.
189 o Assembler AES (***DONE)
191 o Implement the defined SilcDH API. The definition is in
192 lib/silccrypt/silcdh.h. (1.2)
194 o SSH2 public keys support, allowing the use of SSH2 public keys in
197 o Add DSS support (1.2)
199 o ECDSA and ECDH (1.2)
202 lib/silcutil ****PARTLY DONE****
205 o The regex code from lib/contrib might compile fine on all platforms.
206 No need to make it silcutil/unix/ specific. Add them to generic
209 o silc_stringprep to non-allocating version.
211 o Compression routines are missing. The protocol supports packet
212 compression thus it must be implemented. SILC Zip API must be
215 o bool -> SilcBool (***DONE)
217 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
219 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
220 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
224 lib/silcutil/silcbuffer.h ****DONE****
225 =========================
227 o Remove the `truelen' field from SilcBuffer as it is entirely
228 redundant since we can get the true length of the buffer by
229 doing buffer->end - buffer->header. Add silc_buffer_truelen
230 macro instead. Consider also removing `len' field too since
231 it effectively is buffer->tail - buffer->data, and adding
232 silc_buffer_len macro can do the same. These would save
233 totally 8 bytes of memory per buffer. (***DONE)
236 lib/silcutil/silcbuffmt.[ch] ****DONE****
237 ============================
239 o SilcStack aware silc_buffer_unformat (***DONE)
241 o SilcStack aware silc_buffer_format (***DONE)
243 o silc_buffer_format reallocates automatically (***DONE)
245 o SILC_STR_OFFSET (***DONE)
248 lib/silcutil/silcstack.[ch] ****DONE****
249 ===========================
251 o Data stack implementation (***DONE)
254 lib/silcutil/silcstream.[ch] ****DONE****
255 ============================
257 o Add abstract SilcStream. (***DONE)
260 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
261 ==================================
263 o Add SilcSocketStream (***DONE)
265 o Add SilcSocketStream for WIN32
267 o Handle EOS sending to upper layer properly
269 o Test QoS after the changes made to socket stream
272 lib/silcutil/silcschedule*.[ch] ****PARTLY DONE****
273 ===============================
275 o Scheduler can be optimized for FD tasks by changing the fd_queue
276 to SilcHashTable instead of using linked list. We need to do
277 one-to-one mapping of FD to task and hash table is more efficient
280 Also redefine the silc_select to perhaps return a separate
281 structure of the events that actually occurred, instead of
282 returning the events in the fd_list which is then traversed
283 in the generic code to find the changed events. This can be
284 made faster by having own struct which includes only the
285 changed events, thus the tarversing is faster since the whole
286 fd_list is not traversed anymore (it is still traversed in the
287 silc_select but at least it removes one extra tarversing later
290 Other task queues should be changed to use SilcList. (***DONE)
292 o Add SILC scheduler's internal routines into a table of implementation
293 function pointers, that the generic code then takes as extern from
294 implementation. These are the silc_schedule_internal_* routines.
297 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
298 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
300 o SILC Schedule API changes to WIN32.
303 lib/silcutil/silcasync.[ch] ****DONE****
304 ===========================
306 o Add SilcAsyncOperation to utility library. Any function that takes
307 callback as an argument must/should return SilcAsyncOperation.
311 lib/silcutil/silctime.[ch] ****PARTLY DONE****
312 ===========================
314 o SilcTime. (***DONE)
316 o system time, universal, generalized. (***DONE)
318 o Fix universal time decoding (doesn't accept all forms) in silctime.c.
321 lib/silcutil/silcfsm.[ch] ****DONE****
322 =========================
324 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
327 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
328 ===============================================
330 o Add UDP interface (***DONE)
332 o Add UDP interface for WIN32
334 o New network interfaces (***DONE)
340 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
341 client and client library, but TMA in server, due to the significantly
342 increased memory consumption with TFM, and the rare need for public
343 key operations in server.
345 o Change LTM and TFM function names when importing to SILC tree to avoid
346 rare linking problems on system that has same named symbols already in
349 o The SILC MP API function must start returning indication of success
350 and failure of the operation.
352 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
353 any other MP function (including utility ones) that may allocate
358 o All utility functions should be made non-allocating ones.
361 lib/silcutil/symbian/ ****PARTLY DONE****
362 =====================
364 o lib/silcutil/symbian routines missing or not completed.
367 o Something needs to be thought to the logging globals as well,
368 like silc_debug etc. They won't work on EPOC. Perhaps logging
369 and debugging is to be disabled on EPOC.
372 lib/silcasn1 ****PARTLY DONE****
375 o ASN.1 library (***DONE)
377 o Header documentation missing. (***DONE)
379 o Some string encodings missing (copy/paste matter). (***DONE)
381 o Negative integer encoding
387 o All payload encoding routines should take SilcStack as argument. (1.2)
389 o All payload test routines into lib/silccore/tests/.
395 o PKIX implementation
401 o OpenPGP certificate support, allowing the use of PGP public keys
408 o (Re)write commands/command replys.
410 o (Re)write notify handling.
412 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
413 cause sending of multiple SIGNOFF notify's instead of the one
414 SERVER_SIGNOFF notify that the server received. This should be
415 optimized so that the only SERVER_SIGNOFF is sent and not
416 SIGNOFF of notify at all (using SIGNOFF takes the idea about
417 SERVER_SIGNOFF away entirely).
419 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
420 sent to a client if it is on same channel as the client that
421 signoffed. However, the entire SERVER_SIGNOFF list is sent to
422 the client, ie. it may receive clients that was not on the
423 same channel. This is actually against the specs. It must be
424 done per channel. It shouldn't receive the whole list just
425 because one client happened to be on same channel.
427 o MAYBE: The SilcChannelClientEntry can be:
431 where address is SilcClientEntry address XOR SilcChannelEntry.
432 You can get SilcClientEntry by doing client = chl->address XOR channel,
433 and SilcChannelEntry by doing channel = chl->address XOR client.
434 As long as the other pointer is always available when accessing the
435 structure this can be done.
437 o Add reference counters to all Silc*Entry structures
439 o SERVICEs support (plugin, SIM)
441 o If client's public key is saved in the server (and doing public key
442 authentication) then the hostname and the username information could
443 be taken from the public key. Should be a configuration option!
445 o Add a timeout to handling incoming JOIN commands. It should be
446 enforced that JOIN command is executed only once in a second or two
447 seconds. Now it is possible to accept n incoming JOIN commands
448 and process them without any timeouts. THis must be employed because
449 each JOIN command will create and distribute the new channel key
450 to everybody on the channel (Fix this to 0.9.x).
452 o Related to above. If multiple JOINs are received in sequence perhaps
453 new key should be created only once, if the JOINs are handeled at the same
454 time. Now we create multiple keys and never end up using them because
455 many JOINs are processed at the same time in sequence. Only the last
456 key ends up being used.
458 o The CMODE cipher & hmac change problem (#101).
