1 TODO for 1.1 And Beyond
2 =======================
4 NOTE: Any item that doesn't have (***DONE) in it, isn't done yet. The
5 (***TESTING NEEDED) means that the item has been done but not yet properly
9 SILC Client ****PARTLY DONE****
12 o Porting to new Toolkit API and new Client Library API
14 o Improve help files, especially /cmode, /cumode and /key.
17 lib/silcclient, The Client Library ***PARTLY DONE****
18 ==================================
20 o silcclient.h clean up and API rewrites.
22 o silcclient_entry.h finishing, all entry relates APIs to this header.
24 o SilcChannelEntry, SilcServerEntry, SilcChannelUser, allocating,
25 freeing, finding, etc. rewrite. Also making them reference counted for
26 multi threads use. (***DONE)
28 o Finish all the missing SILC packet processings, rewrites.
30 o The client_notify.c rewrite. (***TESTING NEEDED)
32 o Resuming to client_register.c (remove client_resume.c)
35 o Rekey rewrite. (***DONE)
37 o Remove protocol.[ch]. (***DONE)
39 o File transfer rewrite.
41 o Starting key exchange directly, rewrite. (***DONE)
43 o Channel messages, channel private keys, channel entires, channel
46 o For many APIs leave the hash context allocations to the caller instead
47 of using client->sha1hash and client->md5hash, or some kind of thread
48 safe (no locking) concept.
50 o Password auth test, public key auth test.
52 o Key agreement rewrite. (***TESTING NEEDED)
54 o Connecting to remote client (***DONE)
56 o peer-to-peer private messages
58 o Private message waiting API (in threads)
60 o client_attrs.c, attributes rewrite. (***TESTING NEEDED)
62 o No SilcBuffer lists back to application in command_reply operations.
63 Convert them all to real lists and/or structures for easier use.
66 o Nickname formatting rewrite. (***TESTING NEEDED)
68 o UDP connections. (***TESTING NEEDED)
70 o in /cmode and /cumode with +r, maybe the public key and private key
71 could be just some "string", which would then match to "string.pub" and
74 o All packet waiting timeout tests and error condition tests.
80 o Porting to use the new util library.
83 lib/silccore/silcpacket.[ch] ****DONE****
84 ============================
86 o SilcPacketEngine. (***DONE)
88 o New SILC Packet API. (***DONE)
91 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
92 ============================
94 o IV Included flag support, UDP transport support (***TESTING NEEDED)
97 lib/silccore/silcid.[ch] ****DONE****
98 ========================
100 o Add silc_id_str2id to accept the destination buffer as argument
101 and thus not require any memory allocation. Same will happen
102 with silc_id_payload_* functions. (***DONE)
104 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
110 o All payload encoding routines should take SilcStack as argument.
112 o All payload test routines into lib/silccore/tests/.
118 o Removing key from the repository is not possible currently. It should
122 lib/silcske/silcske.[ch] ****PARTLY DONE****
123 ========================
125 o IV Included flag support in SKE (***DONE)
127 o UDP transport changes; retransmission support by using exponential
128 backoff algorithm. (***DONE)
130 o SilcConnAuth header file documentation.
133 lib/silccrypt ****PARTLY DONE****
136 o Implement the defined SilcDH API. The definition is in
137 lib/silccrypt/silcdh.h.
139 o SSH2 public keys support, allowing the use of SSH2 public keys in
142 o OpenPGP certificate support, allowing the use of PGP public keys
145 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
146 Move the SILC Public Key routines away from the crypto library into
147 the core library (silccore). silc_pkcs_public/private_key_* routines
148 to silc_public/private_key_* routines. The silc_public_key_* routines
149 should also automatically handle SILC Public Keys, and other keys
150 and certificates as well. Add fe. silcpk.h into silccore. It should
151 also include the Public Key Payload encoding and decoding routines.
156 o Assembler AES (***DONE)
161 lib/silcutil ****PARTLY DONE****
164 o silc_stringprep to non-allocating version.
166 o Compression routines are missing. The protocol supports packet
167 compression thus it must be implemented. SILC Zip API must be
170 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
171 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
174 o bool -> SilcBool (***DONE)
176 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
178 lib/silcutil/silcbuffer.h ****DONE****
179 =========================
181 o Remove the `truelen' field from SilcBuffer as it is entirely
182 redundant since we can get the true length of the buffer by
183 doing buffer->end - buffer->header. Add silc_buffer_truelen
184 macro instead. Consider also removing `len' field too since
185 it effectively is buffer->tail - buffer->data, and adding
186 silc_buffer_len macro can do the same. These would save
187 totally 8 bytes of memory per buffer. (***DONE)
190 lib/silcutil/silcbuffmt.[ch] ****DONE****
191 ============================
193 o SilcStack aware silc_buffer_unformat (***DONE)
195 o SilcStack aware silc_buffer_format (***DONE)
197 o silc_buffer_format reallocates automatically (***DONE)
199 o SILC_STR_OFFSET (***DONE)
202 lib/silcutil/silcstack.[ch] ****DONE****
203 ===========================
205 o Data stack implementation (***DONE)
208 lib/silcutil/silcstream.[ch] ****DONE****
209 ============================
211 o Add abstract SilcStream. (***DONE)
214 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
215 ==================================
217 o Add SilcSocketStream (***DONE)
219 o Add SilcSocketStream for WIN32
221 o Handle EOS sending to upper layer properly
223 o Test QoS after the changes made to socket stream
226 lib/silcutil/silcschedule*.[ch] ****PARTLY DONE****
227 ===============================
229 o Scheduler can be optimized for FD tasks by changing the fd_queue
230 to SilcHashTable instead of using linked list. We need to do
231 one-to-one mapping of FD to task and hash table is more efficient
234 Also redefine the silc_select to perhaps return a separate
235 structure of the events that actually occurred, instead of
236 returning the events in the fd_list which is then traversed
237 in the generic code to find the changed events. This can be
238 made faster by having own struct which includes only the
239 changed events, thus the tarversing is faster since the whole
240 fd_list is not traversed anymore (it is still traversed in the
241 silc_select but at least it removes one extra tarversing later
244 Other task queues should be changed to use SilcList. (***DONE)
246 o Add SILC scheduler's internal routines into a table of implementation
247 function pointers, that the generic code then takes as extern from
248 implementation. These are the silc_schedule_internal_* routines.
251 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
252 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
254 o SILC Schedule API changes to WIN32.
257 lib/silcutil/silcasync.[ch] ****DONE****
258 ===========================
260 o Add SilcAsyncOperation to utility library. Any function that takes
261 callback as an argument must/should return SilcAsyncOperation.
265 lib/silcutil/silctime.[ch] ****DONE****
266 ===========================
268 o SilcTime. (***DONE)
270 o system time, universal, generalized. (***DONE)
273 lib/silcutil/silcfsm.[ch] ****DONE****
274 =========================
276 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
279 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
280 ===============================================
282 o Add UDP interface (***DONE)
284 o Add UDP interface for WIN32
286 o New network interfaces (***DONE)
292 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
293 client and client library, but TMA in server, due to the significantly
294 increased memory consumption with TFM, and the rare need for public
295 key operations in server.
297 o Change LTM and TFM function names when importing to SILC tree to avoid
298 rare linking problems on system that has same named symbols already in
301 o The SILC MP API function must start returning indication of success
302 and failure of the operation.
304 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
305 any other MP function (including utility ones) that may allocate
310 o All utility functions should be made non-allocating ones.
316 o lib/silcutil/epoc routines missing or not completed.
318 o The PKCS#1 also calls global RNG (even though it is not used
319 currently in SILC, the interface allows its use).
321 o Something needs to be thought to the logging globals as well,
322 like silc_debug etc. They won't work on EPOC. Perhaps logging
323 and debugging is to be disabled on EPOC.
326 lib/silcasn1 ****PARTLY DONE****
329 o ASN.1 library (***DONE)
331 o Header documentation missing. (***DONE)
333 o Some string encodings missing (copy/paste matter). (***DONE)
335 o Negative integer encoding
341 o PKIX implementation
347 o (Re)write commands/command replys.
349 o (Re)write notify handling.
351 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
352 cause sending of multiple SIGNOFF notify's instead of the one
353 SERVER_SIGNOFF notify that the server received. This should be
354 optimized so that the only SERVER_SIGNOFF is sent and not
355 SIGNOFF of notify at all (using SIGNOFF takes the idea about
356 SERVER_SIGNOFF away entirely).
358 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
359 sent to a client if it is on same channel as the client that
360 signoffed. However, the entire SERVER_SIGNOFF list is sent to
361 the client, ie. it may receive clients that was not on the
362 same channel. This is actually against the specs. It must be
363 done per channel. It shouldn't receive the whole list just
364 because one client happened to be on same channel.
366 o MAYBE: The SilcChannelClientEntry can be:
370 where address is SilcClientEntry address XOR SilcChannelEntry.
371 You can get SilcClientEntry by doing client = chl->address XOR channel,
372 and SilcChannelEntry by doing channel = chl->address XOR client.
373 As long as the other pointer is always available when accessing the
374 structure this can be done.
376 o Add reference counters to all Silc*Entry structures
378 o SERVICEs support (plugin, SIM)
380 o If client's public key is saved in the server (and doing public key
381 authentication) then the hostname and the username information could
382 be taken from the public key. Should be a configuration option!
384 o Add a timeout to handling incoming JOIN commands. It should be
385 enforced that JOIN command is executed only once in a second or two
386 seconds. Now it is possible to accept n incoming JOIN commands
387 and process them without any timeouts. THis must be employed because
388 each JOIN command will create and distribute the new channel key
389 to everybody on the channel (Fix this to 0.9.x).
391 o Related to above. If multiple JOINs are received in sequence perhaps
392 new key should be created only once, if the JOINs are handeled at the same
393 time. Now we create multiple keys and never end up using them because
394 many JOINs are processed at the same time in sequence. Only the last
395 key ends up being used.
397 o The CMODE cipher & hmac change problem (#101).
