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
10 lib/silccore/silcpacket.[ch] ****DONE****
11 ============================
13 o SilcPacketEngine. (***DONE)
15 o New SILC Packet API. (***DONE)
18 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
19 ============================
21 o IV Included flag support, UDP transport support (***TESTING NEEDED)
24 lib/silccore/silcid.[ch] ****DONE****
25 ========================
27 o Add silc_id_str2id to accept the destination buffer as argument
28 and thus not require any memory allocation. Same will happen
29 with silc_id_payload_* functions. (***DONE)
31 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
37 o All payload encoding routines should take SilcStack as argument.
39 o All payload test routines into lib/silccore/tests/.
45 o Removing key from the repository is not possible currently. It should
49 lib/silcske/silcske.[ch]
50 ========================
52 o IV Included flag support in SKE (***TESTING NEEDED)
54 o UDP transport changes; retransmission support by using exponential
57 o SilcConnAuth header file documentation.
60 lib/silccrypt ****PARTLY DONE****
63 o Implement the defined SilcDH API. The definition is in
64 lib/silccrypt/silcdh.h.
66 o SSH2 public keys support, allowing the use of SSH2 public keys in
69 o OpenPGP certificate support, allowing the use of PGP public keys
72 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
73 Move the SILC Public Key routines away from the crypto library into
74 the core library (silccore). silc_pkcs_public/private_key_* routines
75 to silc_public/private_key_* routines. The silc_public_key_* routines
76 should also automatically handle SILC Public Keys, and other keys
77 and certificates as well. Add fe. silcpk.h into silccore. It should
78 also include the Public Key Payload encoding and decoding routines.
83 o Cipher optimizations (asm, that this) at least for i386 would be nice.
88 lib/silcutil ****PARTLY DONE****
91 o silc_stringprep to non-allocating version.
93 o Compression routines are missing. The protocol supports packet
94 compression thus it must be implemented. SILC Zip API must be
97 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
98 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
101 o bool -> SilcBool (***DONE)
103 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
106 lib/silcutil/silcbuffer.h ****DONE****
107 =========================
109 o Remove the `truelen' field from SilcBuffer as it is entirely
110 redundant since we can get the true length of the buffer by
111 doing buffer->end - buffer->header. Add silc_buffer_truelen
112 macro instead. Consider also removing `len' field too since
113 it effectively is buffer->tail - buffer->data, and adding
114 silc_buffer_len macro can do the same. These would save
115 totally 8 bytes of memory per buffer. (***DONE)
118 lib/silcutil/silcbuffmt.[ch] ****PARTLY DONE****
119 ============================
121 o SilcStack aware silc_buffer_unformat (***DONE)
123 o SilcStack aware silc_buffer_format (***DONE)
125 o silc_buffer_format reallocates automatically (***DONE)
127 o SILC_STR_OFFSET (***DONE)
130 lib/silcutil/silcstack.[ch] ****DONE****
131 ===========================
133 o Data stack implementation (***DONE)
136 lib/silcutil/silcstream.[ch] ****DONE****
137 ============================
139 o Add abstract SilcStream. (***DONE)
142 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
143 ==================================
145 o Add SilcSocketStream (***DONE)
147 o Add SilcSocketStream for WIN32
149 o Handle EOS sending to upper layer properly
151 o Test QoS after the changes made to socket stream
154 lib/silcutil/silcschedule*.[ch] ****DONE****
155 ===============================
157 o Scheduler can be optimized for FD tasks by changing the fd_queue
158 to SilcHashTable instead of using linked list. We need to do
159 one-to-one mapping of FD to task and hash table is more efficient
162 Also redefine the silc_select to perhaps return a separate
163 structure of the events that actually occurred, instead of
164 returning the events in the fd_list which is then traversed
165 in the generic code to find the changed events. This can be
166 made faster by having own struct which includes only the
167 changed events, thus the tarversing is faster since the whole
168 fd_list is not traversed anymore (it is still traversed in the
169 silc_select but at least it removes one extra tarversing later
172 Other task queues should be changed to use SilcList. (***DONE)
174 o Add SILC scheduler's internal routines into a table of implementation
175 function pointers, that the generic code then takes as extern from
176 implementation. These are the silc_schedule_internal_* routines.
179 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
180 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
182 o SILC Schedule API changes to WIN32.
185 lib/silcutil/silcasync.[ch] ****DONE****
186 ===========================
188 o Add SilcAsyncOperation to utility library. Any function that takes
189 callback as an argument must/should return SilcAsyncOperation.
193 lib/silcutil/silctime.[ch] ****DONE****
194 ===========================
196 o SilcTime. (***DONE)
198 o system time, universal, generalized. (***DONE)
201 lib/silcutil/silcfsm.[ch] ****DONE****
202 =========================
204 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
207 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
208 ===============================================
210 o Add UDP interface (***DONE)
212 o Add UDP interface for WIN32
214 o New network interfaces (***DONE)
220 o Porting to use the new util library.
226 o lib/silcutil/epoc routines missing or not completed.
228 o The PKCS#1 also calls global RNG (even though it is not used
229 currently in SILC, the interface allows its use).
231 o Something needs to be thought to the logging globals as well,
232 like silc_debug etc. They won't work on EPOC. Perhaps logging
233 and debugging is to be disabled on EPOC.
239 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
240 client and client library, but TMA in server, due to the significantly
241 increased memory consumption with TFM, and the rare need for public
242 key operations in server.
244 o Change LTM and TFM function names when importing to SILC tree to avoid
245 rare linking problems on system that has same named symbols already in
248 o The SILC MP API function must start returning indication of success
249 and failure of the operation.
251 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
252 any other MP function (including utility ones) that may allocate
257 o All utility functions should be made non-allocating ones.
260 lib/silcasn1 ****PARTLY DONE****
263 o ASN.1 library (***DONE)
265 o Header documentation missing. (***DONE)
267 o Some string encodings missing (copy/paste matter). (***DONE)
269 o Negative integer encoding
275 o PKIX implementation
281 o (Re)write commands/command replys.
283 o (Re)write notify handling.
285 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
286 cause sending of multiple SIGNOFF notify's instead of the one
287 SERVER_SIGNOFF notify that the server received. This should be
288 optimized so that the only SERVER_SIGNOFF is sent and not
289 SIGNOFF of notify at all (using SIGNOFF takes the idea about
290 SERVER_SIGNOFF away entirely).
292 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
293 sent to a client if it is on same channel as the client that
294 signoffed. However, the entire SERVER_SIGNOFF list is sent to
295 the client, ie. it may receive clients that was not on the
296 same channel. This is actually against the specs. It must be
297 done per channel. It shouldn't receive the whole list just
298 because one client happened to be on same channel.
300 o MAYBE: The SilcChannelClientEntry can be:
304 where address is SilcClientEntry address XOR SilcChannelEntry.
305 You can get SilcClientEntry by doing client = chl->address XOR channel,
306 and SilcChannelEntry by doing channel = chl->address XOR client.
307 As long as the other pointer is always available when accessing the
308 structure this can be done.
310 o Add reference counters to all Silc*Entry structures
312 o SERVICEs support (plugin, SIM)
314 o If client's public key is saved in the server (and doing public key
315 authentication) then the hostname and the username information could
316 be taken from the public key. Should be a configuration option!
318 o Add a timeout to handling incoming JOIN commands. It should be
319 enforced that JOIN command is executed only once in a second or two
320 seconds. Now it is possible to accept n incoming JOIN commands
321 and process them without any timeouts. THis must be employed because
322 each JOIN command will create and distribute the new channel key
323 to everybody on the channel (Fix this to 0.9.x).
325 o Related to above. If multiple JOINs are received in sequence perhaps
326 new key should be created only once, if the JOINs are handeled at the same
327 time. Now we create multiple keys and never end up using them because
328 many JOINs are processed at the same time in sequence. Only the last
329 key ends up being used.
331 o The CMODE cipher & hmac change problem (#101).
337 o Some form of rewrite to make it more efficient.
339 o Clear up interfaces.
341 o Remove silc_client_run and silc_client_run_one from calling SilcSchedule.
342 Leave the scheduling entirely to application.
