1 TODO for 1.1 And Beyond
2 =======================
4 NOTE: Any item that doesn't have (***DONE) in it, isn't done yet.
7 lib/silccrypt ****PARTLY DONE****
10 o Implement the defined SilcDH API. The definition is in
11 lib/silccrypt/silcdh.h.
13 o SSH2 public keys support, allowing the use of SSH2 public keys in
16 o OpenPGP certificate support, allowing the use of PGP public keys
19 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
20 Move the SILC Public Key routines away from the crypto library into
21 the core library (silccore). silc_pkcs_public/private_key_* routines
22 to silc_public/private_key_* routines. The silc_public_key_* routines
23 should also automatically handle SILC Public Keys, and other keys
24 and certificates as well. Add fe. silcpk.h into silccore. It should
25 also include the Public Key Payload encoding and decoding routines.
30 o Cipher optimizations (asm, that this) at least for i386 would be nice.
35 lib/silccore/silcpacket.[ch] ****DONE****
36 ============================
38 o SilcPacketEngine. (***DONE)
40 o New SILC Packet API. (***DONE)
43 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
44 ============================
46 o IV Included flag support, UDP transport support (***TESTING NEEDED)
49 lib/silccore/silcid.[ch] ****DONE****
50 ========================
52 o Add silc_id_str2id to accept the destination buffer as argument
53 and thus not require any memory allocation. Same will happen
54 with silc_id_payload_* functions. (***DONE)
56 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
62 o All payload encoding routines should take SilcStack as argument.
65 lib/silcutil ****PARTLY DONE****
68 o silc_stringprep to non-allocating version.
70 o Compression routines are missing. The protocol supports packet
71 compression thus it must be implemented. SILC Zip API must be
74 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
75 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
78 o bool -> SilcBool (***DONE)
80 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
83 lib/silcutil/silcbuffer.h ****DONE****
84 =========================
86 o Remove the `truelen' field from SilcBuffer as it is entirely
87 redundant since we can get the true length of the buffer by
88 doing buffer->end - buffer->header. Add silc_buffer_truelen
89 macro instead. Consider also removing `len' field too since
90 it effectively is buffer->tail - buffer->data, and adding
91 silc_buffer_len macro can do the same. These would save
92 totally 8 bytes of memory per buffer. (***DONE)
95 lib/silcutil/silcbuffmt.[ch] ****PARTLY DONE****
96 ============================
98 o SilcStack aware silc_buffer_unformat
100 o SilcStack aware silc_buffer_format (***DONE)
102 o silc_buffer_format reallocates automatically (***DONE)
104 o SILC_STR_OFFSET (***DONE)
107 lib/silcutil/silcstack.[ch] ****DONE****
108 ===========================
110 o Data stack implementation (***DONE)
113 lib/silcutil/silcstream.[ch] ****DONE****
114 ============================
116 o Add abstract SilcStream. (***DONE)
119 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
120 ==================================
122 o Add SilcSocketStream (***DONE)
124 o Add SilcSocketStream for WIN32
126 o Test QoS after the changes made to socket stream
129 lib/silcutil/silcschedule*.[ch] ****DONE****
130 ===============================
132 o Scheduler can be optimized for FD tasks by changing the fd_queue
133 to SilcHashTable instead of using linked list. We need to do
134 one-to-one mapping of FD to task and hash table is more efficient
137 Also redefine the silc_select to perhaps return a separate
138 structure of the events that actually occurred, instead of
139 returning the events in the fd_list which is then traversed
140 in the generic code to find the changed events. This can be
141 made faster by having own struct which includes only the
142 changed events, thus the tarversing is faster since the whole
143 fd_list is not traversed anymore (it is still traversed in the
144 silc_select but at least it removes one extra tarversing later
147 Other task queues should be changed to use SilcList. (***DONE)
149 o Add SILC scheduler's internal routines into a table of implementation
150 function pointers, that the generic code then takes as extern from
151 implementation. These are the silc_schedule_internal_* routines.
154 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
155 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
157 o SILC Schedule API changes to WIN32.
160 lib/silcutil/silcasync.[ch] ****DONE****
161 ===========================
163 o Add SilcAsyncOperation to utility library. Any function that takes
164 callback as an argument must/should return SilcAsyncOperation.
168 lib/silcutil/silctime.[ch] ****DONE****
169 ===========================
171 o SilcTime. (***DONE)
173 o system time, universal, generalized. (***DONE)
176 lib/silcutil/silcfsm.[ch] ****DONE****
177 =========================
179 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
182 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
183 ===============================================
185 o Add UDP interface (***DONE)
187 o Add UDP interface for WIN32
189 o New network interfaces (***DONE)
195 o lib/silcutil/epoc routines missing or not completed.
197 o The PKCS#1 also calls global RNG (even though it is not used
198 currently in SILC, the interface allows its use).
200 o Something needs to be thought to the logging globals as well,
201 like silc_debug etc. They won't work on EPOC. Perhaps logging
202 and debugging is to be disabled on EPOC.
208 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
209 client and client library, but TMA in server, due to the significantly
210 increased memory consumption with TFM, and the rare need for public
211 key operations in server.
213 o The SILC MP API function must start returning indication of success
214 and failure of the operation.
216 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
217 any other MP function (including utility ones) that may allocate
220 o All utility functions should be made non-allocating ones.
223 lib/silcasn1 ****PARTLY DONE****
226 o ASN.1 library (***DONE)
228 o Header documentation missing. (***DONE)
230 o Some string encodings missing (copy/paste matter). (***DONE)
232 o Negative integer encoding
238 o PKIX implementation
244 o (Re)write commands/command replys.
246 o (Re)write notify handling.
248 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
249 cause sending of multiple SIGNOFF notify's instead of the one
250 SERVER_SIGNOFF notify that the server received. This should be
251 optimized so that the only SERVER_SIGNOFF is sent and not
252 SIGNOFF of notify at all (using SIGNOFF takes the idea about
253 SERVER_SIGNOFF away entirely).
255 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
256 sent to a client if it is on same channel as the client that
257 signoffed. However, the entire SERVER_SIGNOFF list is sent to
258 the client, ie. it may receive clients that was not on the
259 same channel. This is actually against the specs. It must be
260 done per channel. It shouldn't receive the whole list just
261 because one client happened to be on same channel.
263 o MAYBE: The SilcChannelClientEntry can be:
267 where address is SilcClientEntry address XOR SilcChannelEntry.
268 You can get SilcClientEntry by doing client = chl->address XOR channel,
269 and SilcChannelEntry by doing channel = chl->address XOR client.
270 As long as the other pointer is always available when accessing the
271 structure this can be done.
273 o Add reference counters to all Silc*Entry structures
275 o SERVICEs support (plugin, SIM)
277 o If client's public key is saved in the server (and doing public key
278 authentication) then the hostname and the username information could
279 be taken from the public key. Should be a configuration option!
281 o Add a timeout to handling incoming JOIN commands. It should be
282 enforced that JOIN command is executed only once in a second or two
283 seconds. Now it is possible to accept n incoming JOIN commands
284 and process them without any timeouts. THis must be employed because
285 each JOIN command will create and distribute the new channel key
286 to everybody on the channel (Fix this to 0.9.x).
288 o Related to above. If multiple JOINs are received in sequence perhaps
289 new key should be created only once, if the JOINs are handeled at the same
290 time. Now we create multiple keys and never end up using them because
291 many JOINs are processed at the same time in sequence. Only the last
292 key ends up being used.
294 o The CMODE cipher & hmac change problem (#101).
300 o Some form of rewrite to make it more efficient.
302 o Clear up interfaces.
304 o Remove silc_client_run and silc_client_run_one from calling SilcSchedule.
305 Leave the scheduling entirely to application.
