1 TODO for 1.1 And Beyond
2 =======================
4 NOTE: Any item that doesn't have (***DONE) in it, isn't done yet. The

43 o Password auth test, public key auth test.
45 o Starting key exchange directly, rewrite. (***DONE)
47 o Channel messages, channel private keys, channel entires, channel
50 o For many APIs leave the hash context allocations to the caller instead
51 of using client->sha1hash and client->md5hash, or some kind of thread
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)

65 Convert them all to real lists and/or structures for easier use.
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

76 o All packet waiting timeout tests and error condition tests.
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 ACK packet and packet payload.
90 o SilcPacketEngine. (***DONE)
92 o New SILC Packet API. (***DONE)
95 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
96 ============================
98 o IV Included flag support, UDP transport support (***TESTING NEEDED)
101 lib/silccore/silcid.[ch] ****DONE****
102 ========================
104 o Add silc_id_str2id to accept the destination buffer as argument
105 and thus not require any memory allocation. Same will happen
106 with silc_id_payload_* functions. (***DONE)
108 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
114 o All payload encoding routines should take SilcStack as argument.
116 o All payload test routines into lib/silccore/tests/.
122 o Removing key from the repository is not possible currently. It should
126 lib/silcske/silcske.[ch] ****DONE****
127 ========================
129 o IV Included flag support in SKE (***DONE)
131 o UDP transport changes; retransmission support by using exponential
132 backoff algorithm. (***DONE)
134 o SilcConnAuth header file documentation. (***DONE)
137 lib/silccrypt ****PARTLY DONE****
140 o Implement SILC Public Key Version 2 handling in sign/verify. Implement
141 Version (V) identifier.
143 o Implement PKCS #1 sign/verify with hash OID.
145 o Implement the defined SilcDH API. The definition is in
146 lib/silccrypt/silcdh.h.
148 o SSH2 public keys support, allowing the use of SSH2 public keys in
151 o OpenPGP certificate support, allowing the use of PGP public keys
154 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
155 Move the SILC Public Key routines away from the crypto library into
156 the core library (silccore). silc_pkcs_public/private_key_* routines
157 to silc_public/private_key_* routines. The silc_public_key_* routines
158 should also automatically handle SILC Public Keys, and other keys
159 and certificates as well. Add fe. silcpk.h into silccore. It should
160 also include the Public Key Payload encoding and decoding routines.
165 o Assembler AES (***DONE)
170 lib/silcutil ****PARTLY DONE****
173 o The regex code from lib/contrib might compile fine on all platforms.
174 No need to make it silcutil/unix/ specific. Add them to generic
177 o silc_stringprep to non-allocating version.
179 o Compression routines are missing. The protocol supports packet
180 compression thus it must be implemented. SILC Zip API must be
183 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
184 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
187 o bool -> SilcBool (***DONE)
189 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
191 lib/silcutil/silcbuffer.h ****DONE****
192 =========================
194 o Remove the `truelen' field from SilcBuffer as it is entirely
195 redundant since we can get the true length of the buffer by
196 doing buffer->end - buffer->header. Add silc_buffer_truelen
197 macro instead. Consider also removing `len' field too since
198 it effectively is buffer->tail - buffer->data, and adding
199 silc_buffer_len macro can do the same. These would save
200 totally 8 bytes of memory per buffer. (***DONE)
203 lib/silcutil/silcbuffmt.[ch] ****DONE****
204 ============================
206 o SilcStack aware silc_buffer_unformat (***DONE)
208 o SilcStack aware silc_buffer_format (***DONE)
210 o silc_buffer_format reallocates automatically (***DONE)
212 o SILC_STR_OFFSET (***DONE)
215 lib/silcutil/silcstack.[ch] ****DONE****
216 ===========================
218 o Data stack implementation (***DONE)
221 lib/silcutil/silcstream.[ch] ****DONE****
222 ============================
224 o Add abstract SilcStream. (***DONE)
227 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
228 ==================================
230 o Add SilcSocketStream (***DONE)
232 o Add SilcSocketStream for WIN32
234 o Handle EOS sending to upper layer properly
236 o Test QoS after the changes made to socket stream
239 lib/silcutil/silcschedule*.[ch] ****PARTLY DONE****
240 ===============================
242 o Scheduler can be optimized for FD tasks by changing the fd_queue
243 to SilcHashTable instead of using linked list. We need to do
244 one-to-one mapping of FD to task and hash table is more efficient
247 Also redefine the silc_select to perhaps return a separate
248 structure of the events that actually occurred, instead of
249 returning the events in the fd_list which is then traversed
250 in the generic code to find the changed events. This can be
251 made faster by having own struct which includes only the
252 changed events, thus the tarversing is faster since the whole
253 fd_list is not traversed anymore (it is still traversed in the
254 silc_select but at least it removes one extra tarversing later
257 Other task queues should be changed to use SilcList. (***DONE)
259 o Add SILC scheduler's internal routines into a table of implementation
260 function pointers, that the generic code then takes as extern from
261 implementation. These are the silc_schedule_internal_* routines.
264 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
265 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
267 o SILC Schedule API changes to WIN32.
270 lib/silcutil/silcasync.[ch] ****DONE****
271 ===========================
273 o Add SilcAsyncOperation to utility library. Any function that takes
274 callback as an argument must/should return SilcAsyncOperation.
278 lib/silcutil/silctime.[ch] ****DONE****
279 ===========================
281 o SilcTime. (***DONE)
283 o system time, universal, generalized. (***DONE)
286 lib/silcutil/silcfsm.[ch] ****DONE****
287 =========================
289 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
292 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
293 ===============================================
295 o Add UDP interface (***DONE)
297 o Add UDP interface for WIN32
299 o New network interfaces (***DONE)
305 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
306 client and client library, but TMA in server, due to the significantly
307 increased memory consumption with TFM, and the rare need for public
308 key operations in server.
310 o Change LTM and TFM function names when importing to SILC tree to avoid
311 rare linking problems on system that has same named symbols already in
314 o The SILC MP API function must start returning indication of success
315 and failure of the operation.
317 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
318 any other MP function (including utility ones) that may allocate
323 o All utility functions should be made non-allocating ones.
326 lib/silcutil/symbian/ ****PARTLY DONE****
327 =====================
329 o lib/silcutil/symbian routines missing or not completed.
332 o Something needs to be thought to the logging globals as well,
333 like silc_debug etc. They won't work on EPOC. Perhaps logging
334 and debugging is to be disabled on EPOC.
337 lib/silcasn1 ****PARTLY DONE****
340 o ASN.1 library (***DONE)
342 o Header documentation missing. (***DONE)
344 o Some string encodings missing (copy/paste matter). (***DONE)
346 o Negative integer encoding
352 o PKIX implementation
358 o (Re)write commands/command replys.
360 o (Re)write notify handling.
362 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
363 cause sending of multiple SIGNOFF notify's instead of the one
364 SERVER_SIGNOFF notify that the server received. This should be
365 optimized so that the only SERVER_SIGNOFF is sent and not
366 SIGNOFF of notify at all (using SIGNOFF takes the idea about
367 SERVER_SIGNOFF away entirely).
369 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
370 sent to a client if it is on same channel as the client that
371 signoffed. However, the entire SERVER_SIGNOFF list is sent to
372 the client, ie. it may receive clients that was not on the
373 same channel. This is actually against the specs. It must be
374 done per channel. It shouldn't receive the whole list just
375 because one client happened to be on same channel.
377 o MAYBE: The SilcChannelClientEntry can be:
381 where address is SilcClientEntry address XOR SilcChannelEntry.
382 You can get SilcClientEntry by doing client = chl->address XOR channel,
383 and SilcChannelEntry by doing channel = chl->address XOR client.
384 As long as the other pointer is always available when accessing the
385 structure this can be done.
387 o Add reference counters to all Silc*Entry structures
389 o SERVICEs support (plugin, SIM)
391 o If client's public key is saved in the server (and doing public key
392 authentication) then the hostname and the username information could
393 be taken from the public key. Should be a configuration option!
395 o Add a timeout to handling incoming JOIN commands. It should be
396 enforced that JOIN command is executed only once in a second or two
397 seconds. Now it is possible to accept n incoming JOIN commands
398 and process them without any timeouts. THis must be employed because
399 each JOIN command will create and distribute the new channel key
400 to everybody on the channel (Fix this to 0.9.x).
402 o Related to above. If multiple JOINs are received in sequence perhaps
403 new key should be created only once, if the JOINs are handeled at the same
404 time. Now we create multiple keys and never end up using them because
405 many JOINs are processed at the same time in sequence. Only the last
406 key ends up being used.
408 o The CMODE cipher & hmac change problem (#101).
