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/silccore/silcpacket.[ch] ****DONE****
8 ============================
10 o SilcPacketEngine. (***DONE)
12 o New SILC Packet API. (***DONE)
15 lib/silccore/silcpacket.[ch] ****PARTLY DONE****
16 ============================
18 o IV Included flag support, UDP transport support (***TESTING NEEDED)
21 lib/silccore/silcid.[ch] ****DONE****
22 ========================
24 o Add silc_id_str2id to accept the destination buffer as argument
25 and thus not require any memory allocation. Same will happen
26 with silc_id_payload_* functions. (***DONE)
28 o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
34 o All payload encoding routines should take SilcStack as argument.
37 lib/silcske/silcske.[ch]
38 ========================
40 o IV Included flag support in SKE (it currently doesn't accept it)
42 o SilcConnAuth header file documentation.
45 lib/silccrypt ****PARTLY DONE****
48 o Implement the defined SilcDH API. The definition is in
49 lib/silccrypt/silcdh.h.
51 o SSH2 public keys support, allowing the use of SSH2 public keys in
54 o OpenPGP certificate support, allowing the use of PGP public keys
57 o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
58 Move the SILC Public Key routines away from the crypto library into
59 the core library (silccore). silc_pkcs_public/private_key_* routines
60 to silc_public/private_key_* routines. The silc_public_key_* routines
61 should also automatically handle SILC Public Keys, and other keys
62 and certificates as well. Add fe. silcpk.h into silccore. It should
63 also include the Public Key Payload encoding and decoding routines.
68 o Cipher optimizations (asm, that this) at least for i386 would be nice.
73 lib/silcutil ****PARTLY DONE****
76 o silc_stringprep to non-allocating version.
78 o Compression routines are missing. The protocol supports packet
79 compression thus it must be implemented. SILC Zip API must be
82 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
83 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
86 o bool -> SilcBool (***DONE)
88 o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
91 lib/silcutil/silcbuffer.h ****DONE****
92 =========================
94 o Remove the `truelen' field from SilcBuffer as it is entirely
95 redundant since we can get the true length of the buffer by
96 doing buffer->end - buffer->header. Add silc_buffer_truelen
97 macro instead. Consider also removing `len' field too since
98 it effectively is buffer->tail - buffer->data, and adding
99 silc_buffer_len macro can do the same. These would save
100 totally 8 bytes of memory per buffer. (***DONE)
103 lib/silcutil/silcbuffmt.[ch] ****PARTLY DONE****
104 ============================
106 o SilcStack aware silc_buffer_unformat
108 o SilcStack aware silc_buffer_format (***DONE)
110 o silc_buffer_format reallocates automatically (***DONE)
112 o SILC_STR_OFFSET (***DONE)
115 lib/silcutil/silcstack.[ch] ****DONE****
116 ===========================
118 o Data stack implementation (***DONE)
121 lib/silcutil/silcstream.[ch] ****DONE****
122 ============================
124 o Add abstract SilcStream. (***DONE)
127 lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
128 ==================================
130 o Add SilcSocketStream (***DONE)
132 o Add SilcSocketStream for WIN32
134 o Test QoS after the changes made to socket stream
137 lib/silcutil/silcschedule*.[ch] ****DONE****
138 ===============================
140 o Scheduler can be optimized for FD tasks by changing the fd_queue
141 to SilcHashTable instead of using linked list. We need to do
142 one-to-one mapping of FD to task and hash table is more efficient
145 Also redefine the silc_select to perhaps return a separate
146 structure of the events that actually occurred, instead of
147 returning the events in the fd_list which is then traversed
148 in the generic code to find the changed events. This can be
149 made faster by having own struct which includes only the
150 changed events, thus the tarversing is faster since the whole
151 fd_list is not traversed anymore (it is still traversed in the
152 silc_select but at least it removes one extra tarversing later
155 Other task queues should be changed to use SilcList. (***DONE)
157 o Add SILC scheduler's internal routines into a table of implementation
158 function pointers, that the generic code then takes as extern from
159 implementation. These are the silc_schedule_internal_* routines.
162 o Change SILC_TASK_CALLBACK to non-static, and remove the macro
163 SILC_TASK_CALLBACK_GLOBAL. (***DONE)
165 o SILC Schedule API changes to WIN32.
168 lib/silcutil/silcasync.[ch] ****DONE****
169 ===========================
171 o Add SilcAsyncOperation to utility library. Any function that takes
172 callback as an argument must/should return SilcAsyncOperation.
176 lib/silcutil/silctime.[ch] ****DONE****
177 ===========================
179 o SilcTime. (***DONE)
181 o system time, universal, generalized. (***DONE)
184 lib/silcutil/silcfsm.[ch] ****DONE****
185 =========================
187 o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
190 lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
191 ===============================================
193 o Add UDP interface (***DONE)
195 o Add UDP interface for WIN32
197 o New network interfaces (***DONE)
203 o Porting to use the new util library.
209 o lib/silcutil/epoc routines missing or not completed.
211 o The PKCS#1 also calls global RNG (even though it is not used
212 currently in SILC, the interface allows its use).
214 o Something needs to be thought to the logging globals as well,
215 like silc_debug etc. They won't work on EPOC. Perhaps logging
216 and debugging is to be disabled on EPOC.
222 o Import TFM. Talk to Tom to add the missing functions. Use TFM in
223 client and client library, but TMA in server, due to the significantly
224 increased memory consumption with TFM, and the rare need for public
225 key operations in server.
227 o Change LTM and TFM function names when importing to SILC tree to avoid
228 rare linking problems on system that has same named symbols already in
231 o The SILC MP API function must start returning indication of success
232 and failure of the operation.
234 o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
235 any other MP function (including utility ones) that may allocate
238 o All utility functions should be made non-allocating ones.
241 lib/silcasn1 ****PARTLY DONE****
244 o ASN.1 library (***DONE)
246 o Header documentation missing. (***DONE)
248 o Some string encodings missing (copy/paste matter). (***DONE)
250 o Negative integer encoding
256 o PKIX implementation
262 o (Re)write commands/command replys.
264 o (Re)write notify handling.
266 o The SERVER_SIGNOFF notify handing is not optimal, because it'll
267 cause sending of multiple SIGNOFF notify's instead of the one
268 SERVER_SIGNOFF notify that the server received. This should be
269 optimized so that the only SERVER_SIGNOFF is sent and not
270 SIGNOFF of notify at all (using SIGNOFF takes the idea about
271 SERVER_SIGNOFF away entirely).
273 o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
274 sent to a client if it is on same channel as the client that
275 signoffed. However, the entire SERVER_SIGNOFF list is sent to
276 the client, ie. it may receive clients that was not on the
277 same channel. This is actually against the specs. It must be
278 done per channel. It shouldn't receive the whole list just
279 because one client happened to be on same channel.
281 o MAYBE: The SilcChannelClientEntry can be:
285 where address is SilcClientEntry address XOR SilcChannelEntry.
286 You can get SilcClientEntry by doing client = chl->address XOR channel,
287 and SilcChannelEntry by doing channel = chl->address XOR client.
288 As long as the other pointer is always available when accessing the
289 structure this can be done.
291 o Add reference counters to all Silc*Entry structures
293 o SERVICEs support (plugin, SIM)
295 o If client's public key is saved in the server (and doing public key
296 authentication) then the hostname and the username information could
297 be taken from the public key. Should be a configuration option!
299 o Add a timeout to handling incoming JOIN commands. It should be
300 enforced that JOIN command is executed only once in a second or two
301 seconds. Now it is possible to accept n incoming JOIN commands
302 and process them without any timeouts. THis must be employed because
303 each JOIN command will create and distribute the new channel key
304 to everybody on the channel (Fix this to 0.9.x).
306 o Related to above. If multiple JOINs are received in sequence perhaps
307 new key should be created only once, if the JOINs are handeled at the same
308 time. Now we create multiple keys and never end up using them because
309 many JOINs are processed at the same time in sequence. Only the last
310 key ends up being used.
312 o The CMODE cipher & hmac change problem (#101).
318 o Some form of rewrite to make it more efficient.
320 o Clear up interfaces.
322 o Remove silc_client_run and silc_client_run_one from calling SilcSchedule.
323 Leave the scheduling entirely to application.
