52 safe (no locking) concept.
54 o Key agreement rewrite. (***TESTING NEEDED)
56 o Connecting to remote client (***DONE)
58 o peer-to-peer private messages
60 o Private message waiting API (in threads)

68 o Nickname formatting rewrite. (***TESTING NEEDED)
70 o UDP connections. (***TESTING NEEDED)
72 o in /cmode and /cumode with +r, maybe the public key and private key

79 lib/silcsftp ****DONE****
82 o Porting to use the new util library. (***DONE)
85 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
86 ============================
88 o Implement silc_packet_engine_stop and silc_packet_stream_destroy.
90 o Implement ACK packet and packet payload.
92 o SilcPacketEngine. (***DONE)
94 o New SILC Packet API. (***DONE)
97 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
98 ============================
100 o IV Included flag support, UDP transport support (***TESTING NEEDED)
103 lib/silccore/silcid.[ch] ****DONE****
104 ========================
106 o Add silc_id_str2id to accept the destination buffer as argument
107 and thus not require any memory allocation. Same will happen
108 with silc_id_payload_* functions. (***DONE)
110 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
116 o All payload encoding routines should take SilcStack as argument.
118 o All payload test routines into lib/silccore/tests/.
124 o Removing key from the repository is not possible currently. It should
128 lib/silcske/silcske.[ch] ****DONE****
129 ========================
131 o IV Included flag support in SKE (***DONE)
133 o UDP transport changes; retransmission support by using exponential
134 backoff algorithm. (***DONE)
136 o SilcConnAuth header file documentation. (***DONE)
139 lib/silccrypt ****PARTLY DONE****
142 o Implement SILC Public Key Version 2 handling in sign/verify. Implement
143 Version (V) identifier (***DONE)
145 o Implement PKCS #1 sign/verify with hash OID. (***TESTING NEEDED)
147 o Implement the defined SilcDH API. The definition is in
148 lib/silccrypt/silcdh.h.
150 o SSH2 public keys support, allowing the use of SSH2 public keys in
153 o OpenPGP certificate support, allowing the use of PGP public keys
156 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
157 Move the SILC Public Key routines away from the crypto library into
158 the core library (silccore). silc_pkcs_public/private_key_* routines
159 to silc_public/private_key_* routines. The silc_public_key_* routines
160 should also automatically handle SILC Public Keys, and other keys
161 and certificates as well. Add fe. silcpk.h into silccore. It should
162 also include the Public Key Payload encoding and decoding routines.
167 o Assembler AES (***DONE)
172 lib/silcutil ****PARTLY DONE****
175 o The regex code from lib/contrib might compile fine on all platforms.
176 No need to make it silcutil/unix/ specific. Add them to generic
179 o silc_stringprep to non-allocating version.
181 o Compression routines are missing. The protocol supports packet
182 compression thus it must be implemented. SILC Zip API must be
185 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
186 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
189 o bool -> SilcBool (***DONE)
191 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
193 lib/silcutil/silcbuffer.h ****DONE****
194 =========================
196 o Remove the `truelen' field from SilcBuffer as it is entirely
197 redundant since we can get the true length of the buffer by
198 doing buffer->end - buffer->header. Add silc_buffer_truelen
199 macro instead. Consider also removing `len' field too since
200 it effectively is buffer->tail - buffer->data, and adding
201 silc_buffer_len macro can do the same. These would save
202 totally 8 bytes of memory per buffer. (***DONE)
205 lib/silcutil/silcbuffmt.[ch] ****DONE****
206 ============================
208 o SilcStack aware silc_buffer_unformat (***DONE)
210 o SilcStack aware silc_buffer_format (***DONE)
212 o silc_buffer_format reallocates automatically (***DONE)
214 o SILC_STR_OFFSET (***DONE)
217 lib/silcutil/silcstack.[ch] ****DONE****
218 ===========================
220 o Data stack implementation (***DONE)
223 lib/silcutil/silcstream.[ch] ****DONE****
224 ============================
226 o Add abstract SilcStream. (***DONE)
229 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
230 ==================================
232 o Add SilcSocketStream (***DONE)
234 o Add SilcSocketStream for WIN32
236 o Handle EOS sending to upper layer properly
238 o Test QoS after the changes made to socket stream
241 lib/silcutil/silcschedule*.[ch] ****PARTLY DONE****
242 ===============================
244 o Scheduler can be optimized for FD tasks by changing the fd_queue
245 to SilcHashTable instead of using linked list. We need to do
246 one-to-one mapping of FD to task and hash table is more efficient
249 Also redefine the silc_select to perhaps return a separate
250 structure of the events that actually occurred, instead of
251 returning the events in the fd_list which is then traversed
252 in the generic code to find the changed events. This can be
253 made faster by having own struct which includes only the
254 changed events, thus the tarversing is faster since the whole
255 fd_list is not traversed anymore (it is still traversed in the
256 silc_select but at least it removes one extra tarversing later
259 Other task queues should be changed to use SilcList. (***DONE)
261 o Add SILC scheduler's internal routines into a table of implementation
262 function pointers, that the generic code then takes as extern from
263 implementation. These are the silc_schedule_internal_* routines.
266 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
267 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
269 o SILC Schedule API changes to WIN32.
272 lib/silcutil/silcasync.[ch] ****DONE****
273 ===========================
275 o Add SilcAsyncOperation to utility library. Any function that takes
276 callback as an argument must/should return SilcAsyncOperation.
280 lib/silcutil/silctime.[ch] ****DONE****
281 ===========================
283 o SilcTime. (***DONE)
285 o system time, universal, generalized. (***DONE)
288 lib/silcutil/silcfsm.[ch] ****DONE****
289 =========================
291 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
294 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
295 ===============================================
297 o Add UDP interface (***DONE)
299 o Add UDP interface for WIN32
301 o New network interfaces (***DONE)
307 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
308 client and client library, but TMA in server, due to the significantly
309 increased memory consumption with TFM, and the rare need for public
310 key operations in server.
312 o Change LTM and TFM function names when importing to SILC tree to avoid
313 rare linking problems on system that has same named symbols already in
316 o The SILC MP API function must start returning indication of success
317 and failure of the operation.
319 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
320 any other MP function (including utility ones) that may allocate
325 o All utility functions should be made non-allocating ones.
328 lib/silcutil/symbian/ ****PARTLY DONE****
329 =====================
331 o lib/silcutil/symbian routines missing or not completed.
334 o Something needs to be thought to the logging globals as well,
335 like silc_debug etc. They won't work on EPOC. Perhaps logging
336 and debugging is to be disabled on EPOC.
339 lib/silcasn1 ****PARTLY DONE****
342 o ASN.1 library (***DONE)
344 o Header documentation missing. (***DONE)
346 o Some string encodings missing (copy/paste matter). (***DONE)
348 o Negative integer encoding
354 o PKIX implementation
360 o (Re)write commands/command replys.
362 o (Re)write notify handling.
364 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
365 cause sending of multiple SIGNOFF notify's instead of the one
366 SERVER_SIGNOFF notify that the server received. This should be
367 optimized so that the only SERVER_SIGNOFF is sent and not
368 SIGNOFF of notify at all (using SIGNOFF takes the idea about
369 SERVER_SIGNOFF away entirely).
371 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
372 sent to a client if it is on same channel as the client that
373 signoffed. However, the entire SERVER_SIGNOFF list is sent to
374 the client, ie. it may receive clients that was not on the
375 same channel. This is actually against the specs. It must be
376 done per channel. It shouldn't receive the whole list just
377 because one client happened to be on same channel.
379 o MAYBE: The SilcChannelClientEntry can be:
383 where address is SilcClientEntry address XOR SilcChannelEntry.
384 You can get SilcClientEntry by doing client = chl->address XOR channel,
385 and SilcChannelEntry by doing channel = chl->address XOR client.
386 As long as the other pointer is always available when accessing the
387 structure this can be done.
389 o Add reference counters to all Silc*Entry structures
391 o SERVICEs support (plugin, SIM)
393 o If client's public key is saved in the server (and doing public key
394 authentication) then the hostname and the username information could
395 be taken from the public key. Should be a configuration option!
397 o Add a timeout to handling incoming JOIN commands. It should be
398 enforced that JOIN command is executed only once in a second or two
399 seconds. Now it is possible to accept n incoming JOIN commands
400 and process them without any timeouts. THis must be employed because
401 each JOIN command will create and distribute the new channel key
402 to everybody on the channel (Fix this to 0.9.x).
404 o Related to above. If multiple JOINs are received in sequence perhaps
405 new key should be created only once, if the JOINs are handeled at the same
406 time. Now we create multiple keys and never end up using them because
407 many JOINs are processed at the same time in sequence. Only the last
408 key ends up being used.
410 o The CMODE cipher & hmac change problem (#101).
