1 Mon Sep 23 10:59:39 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed double free in RSA public key set function
4 silc_rsa_set_public_key. Affected file lib/silccrypt/rsa.c.
7 Sun Sep 22 14:54:05 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Rewrote WHOIS, WHOWAS and IDENTIFY commands in the server.
10 Added server_query.[ch] which provides one interface for
11 querying information using all three commands.
13 * Changed all "typedef unsigned char" in core library to
16 Sat Sep 21 21:36:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
18 * Added silc_strncat into lib/silcutil/silcstrutil.[ch].
20 * Renamed silc_server_get_client_resolve to
21 silc_server_query_resolve and moved to server_query.[ch].
23 Wed Sep 18 18:28:04 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Resumed client packet handling from server put the resumed
26 client on wrong list on router and caused the client not
27 be present on the network anymore. Now fixed to put the
28 client to correct list. Affected file silcd/packet_receive.c.
30 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
32 * Various cleanup in error message output in config parsing code
33 and in server init code. Fixed error log files containing
34 too many newlines ('\n') in some situations. Affected files are
35 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
37 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
39 * Use the reverse lookupped hostname in client internals
40 instead of one user provided us as remote server name.
41 Affected file lib/silcclient/client.c.
43 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Added 'app_context' to silc_schedule_init. It is an
46 application specific context that is delivered to application
47 in task callback functions. Affected files are
48 lib/silcutil/silcutil.[ch].
50 * The hb_context in SilcSocketConnection is not freed
51 automatically anymore (application must free it). Freeing
52 it automatic is inconsistent. Affected files are
53 lib/silcutil/silcsockconn.[ch].
55 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
57 * Added support for removing explicitly added client connections
58 in rehash and closing the client connections if they were
59 unconfigured in the rehash. Affected file silcd/server.c.
61 * Added support for aborting automatically pending commands
62 that never receives the reply (to avoid memory leaks).
63 Added also silc_server_command_pending_timed to set the
64 specific timeout for pending command. Affected files are
65 silcd/command[_reply].[ch].
67 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
68 specs and lib/silccore/silcstatus.h.
70 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
72 * Changed the silc_get_time to accept time value as argument
73 or if zero is sent return current local time. Affected
74 file lib/silcutil/silcutil.[ch].
76 * Added STATS command to client library and Irssi SILC client.
77 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
79 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Assure that channel key is set before sending it. May
82 crash server otherwise. Affected file silcd/packet_send.c.
84 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
86 * Assure that endless loop cannot happen with detached client
87 resolving on normal server. Added idlist status
88 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
89 silcd/idlist.h and silcd/packet_receive.c.
91 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
93 * Incoming file transfer request cannot use same session as
94 the sending session. This can happen when sending file to
95 yourself. Crashed the client on quit. Affected file
96 lib/silcclient/client_ftp.c. Bug #24.
98 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
100 * Implemented the draft-riikonen-precense-attrs draft and
101 the Attribute Payload into the lib/silccore/silcattrs.[ch].
103 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Distribute the SERVER_SIGNOFF notify also to local backup
106 routers from the primary router. The backup router may not
107 have the signing of local server directly connected and need
108 to know about the signoff. Affected file silcd/server_util.c.
110 * Use the primary router as the origin of the locally connected
111 server when it is disconnecting from the backup router since
112 that's where it really is coming from. Now the clients from
113 the disconnecting server are removed correctly and "shadow"
114 clients are not left to the backup router. Affected file
117 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
119 * If normal server is standalone and found existing but disabled
120 channel, do not re-create the channel since it creates
121 duplicate same channels. Affected file silcd/server.c.
123 * Added anonymous client connections support to server. New
124 "anonymous" configuration option to ConnectionParams section
125 added. If set to true, the username and hostname information
126 of the client will be scrambled and anonymous user mode is
127 set automatically to the user. Affected files are
128 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
130 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
132 * In JOIN notify handling, mark that the cache entry of the
133 client cannot be expired. Can cause crashes on normal
134 server (asserts client->channels). Affected file is
135 silcd/packet_receive.c.
137 * From now on distribution versions are used as protocol versions
138 instead of by default using the Toolkit base version as protocol
139 version. Affected file prepare.
141 * Do not set the locally resolved hostname for local client
142 entry but take what server sends. This way the real hostname
143 is showed in WHOIS for yourself. Affected file is
144 lib/silcclient/idlist.c and lib/silcclient/client.c.
146 * Resolve local info with IDENTIFY when connecting to server.y
148 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
150 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
151 for implied search (not needed on platforms which has native
152 pthreads library). Use --without-pthreads to disable threads.
153 Affected file is configure.in.pre
155 * Fixed --with-iconv on platforms which need to bypass (broken)
156 native iconv(). Affected file is configure.in.pre
158 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
160 * Moved -C option parsing in Irssi SILC client at same time
161 as other options. The UI was initialized earlier and caused
162 problems on command line. Bug #16. Affected file is
163 irssi/src/silc/core/silc-core.c.
165 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
167 * Added global variable silc_log_timestamp that tells silclog
168 wether to print or not the timestamp in the logging files.
169 Affected file lib/silcutil/silclog.[ch].
171 * Added silcd configuration option Timestamp in the Logging
172 section. Affected file silcd/serverconfig.[ch],
173 doc/example_silcd.conf.in.
175 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
177 * Fixed fingerprint checking to check for entirely empty
178 fingerprint instead of two first bytes when determining
179 if it is set. Bug #18. Affected file silcd/command.c.
181 * Fixed duplicate PKCS name registering to not allow it.
182 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
184 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
186 * Conditionalize non-gcc compiler optimizations for various
187 platforms, enable those commented out. Cleanups.
188 Affected file lib/silcmath/mpi/configure.in
190 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
192 * silc_rng_exec_command() left zombie processes if command
193 didn't generate any output. Affected file
194 lib/silccrypt/silcrng.c
196 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
198 * Rewrote iconv checking, introduce --with-iconv for systems
199 which rely on libiconv. Check if iconv() provided by libc
200 is good enough, otherwise demand libiconv. Affected file
203 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
205 * Search for ldopen() also in libc. This enables SIM support
206 on *BSD systems. Based on patch from Alex Zepeda. Affected
207 file configure.in.pre
209 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
211 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
212 This fixes prepare on *BSD systems. Affected file
215 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
217 * More fixed for not having purge timeout for global clients
218 that are on channel. Affected files silcd/command_reply.c
221 * Fixed the rekey protocol to work with backup router connections.
222 Rekey packets are now allowed on disabled connections as
223 well. Affected files silcd/packet_send.c and server.c.
225 * Do not switch to be as backup router when shutting down and
226 closing the primary connection. Affected file silcd/server.c.
228 * Fixed memory leaks in backup router deleting. Added
229 silc_server_backup_free to free all data during shutdown of
230 server. Affected files silcd/server_backup.[ch].
232 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
234 * Do not process commands if the sock->user_data is NULL.
235 Affected file silcd/command.c.
237 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Fixed buffer overflow and security problems (loosing bits
240 in CFB encryption) in SILC RNG. Problems reported by
241 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
243 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Added yet more checks that client is not expired on global
246 list if it is on channels. Affected file is
247 silcd/command_reply.c.
249 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Merged c0ffee's MIME signal patch which adds support for
252 sending also MIME messages in Irssi SILC Client, and handling
253 received MIME messages in a signal (and perhaps doing something
254 to non-textual MIME messages).
256 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
258 * Fixed pending command deletion in server and client library
259 to check the whole list instead of breaking after first found.
260 The affected files are silcd/command.[ch] and
261 lib/silcclient/command.[ch].
263 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
265 * Return NO_SUCH_CHANNEL error in USERS for channel that is
266 secret or private, otherwise it's possible to find out
267 whether a secret channel exists or not. Affected file
270 * If CMODE change fails during the mode setting, assure that
271 the old mode mask is set for the channel back. Affected
272 file silcd/command.c.
274 * Fixed passphrase saving on +a channel on normal server
275 after successful JOIN command. Affected file silcd/command.c.
277 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
279 * Remove server/router operator privileges in DETACH command,
280 since it's possible to resume to server where these
281 privileges would not be allowed for the client. Affected
282 file silcd/command.c.
284 * Do not set to wait for backup in rehash of the server.
285 Affected file silcd/server.c.
287 * Do not check listener sockets when counting how many
288 socket connections we have. Affected file is
291 * Do not announce disconnected clients that are remaining
292 in history (for WHOWAS). This is because SIGNOFF notify
293 for these has been sent earlier already. Affected file
296 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Buffer overflow with CUMODE command's mode->mode character
299 conversion. Reported by Ville Räsänen. Affected file
300 lib/silcutil/silcutil.c.
302 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
304 * Allow heartbeat packets to go disabled connections anyway.
305 Affected files silcd/server.c and silcd/packet_send.c.
307 * Do not broadcast New Channel packets with List flag set
308 in the packet to backup routers. The router must check
309 for the correctness of the packets before sending them.
310 It is possible that router will have enforce Channel ID
311 change and this would cause desync in the backup router.
312 Affected file silcd/packet_receive.c.
314 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
315 are handled in list parsing. They are not list packets
316 anymore. Affected file silcd/packet_receive.c.
318 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
320 * Stop waiting for backup router through the timeout, not
321 directly after backup router has arrived. Affected file
324 * Do not re-create channel keys and send them when removing
325 clients in server shutdown. Affected files are
326 silcd/server_internal.h and silcd/server_util.c.
328 * Notify distribution to backup routers was missing from
329 the silc_server_send_notify_dest function which caused
330 desyncing problems with backup router. Affected file is
333 * The client's channel removing was working wrong on
334 backup router. It assumed that it doesn't know global
335 information but backup router does know. For this reason
336 it could remove channel when it wasn't supposed to do that.
337 Affected file silcd/server.c and silcd/server_util.c.
339 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
341 * Stop for a couple seconds after badkup router has become
342 primary router. Affected file silcd/server.c.
344 * Added silc_server_remove_servers_by_server, which is used
345 to remove servers originated from some other server. Also
346 clients of those servers can be removed too. Affected file
347 silcd/server_util.[ch].
349 * When removing clients after a server has signed of remove
350 also all servers behind that server (unless they are known
351 to be available locally), and send SERVER_SIGNOFF for each
352 of the server separately. Also the signed off clients are
353 sent now separately per signed off server. The affected files
354 are silcd/server.c and silcd/server_util.[ch].
356 * All servers added with silc_idlist_add_server must always
357 have both "router" and "connection" pointers set. Otherwise,
358 bad server entries may be left around in the cache.
359 Affected file silcd/command_reply.c.
361 * Do not create the channel key in NEW_CHANNEL packet
362 processing if the channel is empty. Affected file
363 silcd/packet_receive.c.
365 * Completed backup router support for standalone routers.
366 Supports also servers in the cell that do not use the backup
369 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
371 * Fixed a bug in silc_string_regexify which did not add '^'
372 at the start of each string, and thus the matching was
373 not explicit. For example ban list iikone@*!*@* would
374 match also "priikone", which is wrong, it would have to be
375 *iikone@*!*@* to match also "priikone". Affected
376 file lib/silcutil/unix/silcunixutil.c.
378 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
380 * Enable all local server connections before updating client
381 caches when we've become backup router. Otherwise, signoff
382 packets may not reach the clients. Affected files are
383 silcd/server.c and silcd/server_util.[ch].
385 * Fixed a bug in version string parsing which could crash
386 the program with specially formatted version string.
387 Bug reported and patch provided by Ville Räsänen. Affected
388 file lib/silcutil/silcutil.c.
390 * Handle the disconnection immediately when DISCONNECT
391 packet is received in server. Affected file silcd/server.c.
393 * Primary router now waits a short time (10 seconds) for
394 backup router connection before accepting any other
395 connection (except local). Affected file silcd/server.c,
398 * Fixed a crash in client libary in NICK_CHANGE notify when
399 NICK_CHANGE arrived for client entry we are resolving
400 currently. Affected file lib/silcclient/client_notify.c.
402 * Call the sconn->callback completion even if error had
403 occurred. Start reconnecting always if connection to
404 primary router fails during backup router protocol.
405 Affected files silcd/server.c and server_backup.c.
407 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Added functions silc_server_send_opers and
410 silc_server_send_opers_notify to send packets stricly
411 to operators. Added macro SILC_SERVER_SEND_OPERS macro
412 to send variable argument notify to operators.
413 Affected files silcd/packet_send.[ch] and silcd/server.h.
415 * Removed UMODE rights checking with UMODE_CHANGE notify.
416 Affected file silcd/packet_receive.c.
418 * Server/router operator now receives notify when network
419 switches to backup router and when it resumes the use of
420 primary router. Affected file silcd/server.c and
421 silcd/server_backup.c.
423 * Fixed the updating of client information after backup
424 resuming protocol is over; update all except local clients
425 to the new primary router. The affected file is
428 * Added support for closing active connections in rehash
429 that were unconfigured by the user. Supports currently
430 closing server and router connections. Affected file
433 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
435 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
437 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
438 is NULL since seems that on some platforms NULL is allowed
439 and on some it's not. Fallback encoding is used instead.
440 Affected file lib/silcutil/silcstrutil.c.
442 * Fixed statistics updating for incoming server connection
443 which could cause problems when re-connecting. Affected
446 * Preliminary backup router support for standalone router
447 added. Affected files in silcd/.
449 * Mark server connections in backup router disabled before
450 and after backup protocol. Affected file is
451 silcd/server_backup.c.
453 * Added support for reconnecting to remote server connection
454 even if the protocol fails, and if the configuration wants
455 us to keep trying to connect anyway.
457 Server connection is not allowed to backup router if
458 backup router does not have connection to primary router yet.
460 Affected file is silcd/server.c.
462 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
464 * Added silc_client_udpate_server function to update changed
465 server info. Affected file lib/silcclient/idlist.[ch].
467 * Added check for server entries that are being resolved when
468 notify is received. If being resolved, handle the received
469 notify only after it's resolved so that all notifys are
470 handled in same order as received from the server.
472 Added similar resolver check to channel entries. Every
473 notify that cause resolving of any information that affects
474 channel entry marks the channel entry in waiting state.
475 After whatever resolving is over the waiters are signalled
476 and only then the notifys are handled in the same order
477 as delivered from the server.
479 Affected files are lib/silcclient/idlist.[ch], and
482 * Fixed KILLED notify handling in normal server. Affected
483 file silcd/packet_receive.c.
485 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
486 is locally connected, or was locally connected (but may
487 be detached and connection is not active). Added also
488 SILC_IS_LOCAL for checking this status. Affected files
489 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
490 silcd/server.c and silcd/server_internal.h.
492 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
494 * Don't send or handle TOPIC_SET if topic is already set and
495 is same as being set. Affected files silcd/command.c and
496 silcd/packet_receive.c.
498 * Fixed CMODE change rights checking to work correctly when
499 removing modes by operator. Affected file is
502 * Fixed some handling with New Channel packet in router and
503 fixed some CMODE_CHANGE notify handling in server and router.
504 Affected file is silcd/packet_receive.c.
506 * Changed "disconnect" client operation to include the
507 reason of the disconnection and optional disconnection
508 message. Affected file lib/silcclient/silcclient.h.
510 * Made the compilation of lib/contrib/ stuff conditional.
511 Affected files configure.in.pre, lib/contrib/Makefile.am.
513 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
515 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
516 to the sender of the notify too, to avoid situation where two
517 notifys are in the network at the same time going to oppsite
518 directions. Affected file silcd/packet_receice.c.
520 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
522 * Delete the client from channel even if the cilent->id is
523 NULL. It was possible that client was deleted without
524 removing from channels (theoretically at least). Affected
525 file silcd/server.c and silcd/server_util.c.
527 * Free the client data too when resuming is not successful.
528 Affected file silcd/packet_receive.c.
530 * Merged some code from c0ffee's silc-plugin. Affected files
531 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
533 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
534 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
535 to the primary router connection, the other one returns
536 TRUE if packet must be broadcasted to network.
538 * All notifys that are destined to primary router (to network)
539 are now automatically sent to backup routers even if the
540 router is standalone (and has backup router). Affected files
543 * Added --without-irssi and --without-silcd configuration
544 options for disabling the compilation of these applications.
545 Affected file configure.in.pre and prepare.
547 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
549 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
550 UTF-8 encoding and decoding. Added also new encodings
551 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
553 Added also SILC_STRING_LANGUAGE which is language and charset
554 specific encoder and decoer for those platforms that support
555 iconv(). It can convert the UTF-8 to and from the locale
556 specific character set.
558 Affected file lib/silcutil/silcstrutil.[ch].
560 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
562 * Added function silc_get_command_name to the file

1121 * Added resolve_cmd_ident field to the SilcClientEntry structure
1122 too so that if the entry is for example being resolved so
1123 another command may attach to the same pending command reply
1124 without requiring to resolve the same entry again. Added
1125 support for adding multiple pending commands for one
1126 command idenfier. Affected files lib/silcclient/command.[ch],
1127 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
1129 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1132 and secret channels too. Updated protocol specs and the
1133 code in server. Affected file silcd/command.c.
1135 * Defined <channel user mode list> argument to WHOIS command
1136 reply for returning user modes on the channels. The
1137 channel list now doesn't include the user mode anymore but the
1138 actual channel mode. Updated protocol specs and the code in
1139 client and server. Affected files are silcd/command_reply.c,
1140 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
1141 and lib/silcclient/command_reply.c.
1143 * Save the channels list in WHOIS command reply in normal server
1144 so that WHOIS always shows joined channels also in normal
1145 server and not just on router. Affected file is
1146 silcd/command_reply.c.
1148 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1150 * Defined that server receives USERS command reply for private
1151 and secret channels too. Updated protocol specs and the

1154 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1156 * Changed the UMODE's mode mask argument to be optional. If
1157 not provided then the command merely returns the current mode
1158 mask to the client. Updated protocol specs and the server.
1159 Affected file is silcd/command.c.
1161 * Added SILC session detachment/resuming support. It is possible
1162 to detach by closing the network connection and then re-connect
1163 and resume to the old client session. Added DETACHED user
1164 mode that server will set for detached client. Added new
1165 packet RESUME_CLIENT which is used to perform the resuming
1166 process. Added DETACH command. Updated the protocol specs,
1167 core library, client and server. Protocol TODO #22. Very
1168 many affected files around the tree.
1170 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1172 * Changed the CMODE's mode mask argument to be optional. If
1173 not provided then the command merely returns the current mode
1174 mask to the client. Updated protocol specs and the server.
1175 Affected file is silcd/command.c.
1177 * Changed the Killer's Client ID in KILLED notify to be just
1178 any ID payload since router server is allowed to kill as well.
1179 Updated protocol specs, client libary and server. Affected
1180 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
1181 and irssi/src/silc/core/client_ops.c.
1183 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Added new user modes ANONYMOUS for special anonymous servers
1186 that may set the mode for client, and BLOCK_PRIVMSG which
1187 client may set to block incoming private messages unless the
1188 Private Message Key flag is set (using private keys to protect
1189 private messages). Updated protocol specs and code in client
1190 and server and core library. Protocol TODO #23. Affected
1191 files are lib/silccore/silcmode.h, silcd/server.[ch],
1192 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
1193 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
1195 * Added new channel user mode BLOCK_MESSAGES which the client
1196 may set to itself to tell server not send channel messages.
1197 Other packets such as channel key packets are still sent.
1198 Protocol TODO #23. Updated the protocol specs, client and
1199 server. Affected files are lib/silccore/silcmode.h,
1200 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
1201 lib/silcutil/silcutil.c, silcd/command.c, and
1202 silcd/packet_send.c.
1204 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1206 * Redefined the Status Payload to include now two 8 bit fields,
1207 instead of one 16 bit field. This now makes it possible to
1208 send list of errors. Updated the protocol specs and the code
1209 in core library, client library and server. Protocol TODO #1.
1210 Affected files are lib/silccore/silccommand.[ch],
1211 lib/silcclient/command_reply.[ch], silcd/command.c,
1212 silcd/command_reply.c and silcd/packet_receive.[ch].
1214 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1216 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1217 must be handled by the application and should tell the application
1218 that an error message was already printed, and it should print the
1219 config coords (line, filename, ...). Affected files are
1220 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1222 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1223 server config parsing code more readable.
1225 Fixed a bug in the fetch_logging() config callback.
1227 Affected files is silcd/serverconfig.c.
1229 * Drop root privileges when started in foreground. Don't drop them
1230 if debugging also. Affected file is silcd/silcd.c.

1235 for setting various presence information. Added new modes:
1236 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1237 specs and code. Protocol TODO #19. Affected files are
1238 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1239 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1241 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1243 * Added STATS command to the protocol after all, to return
1244 various statistical information about the network. It can
1245 be used by clients to retrieve statistical information, and
1246 servers may use it to to fetch cell and network wide
1247 statistics from router. Updated the protocol specs and
1248 implemented it to the server. Protocol TODO #16.
1249 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1250 silcd/command_reply.[ch].
1252 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * The LIST command reply in client libary now adds new channel
1255 entry if the returned channel doesn't exist yet in cache,
1256 and returns the channel entry to the application in the
1257 command_reply client operation. Affected file is
1258 lib/silcclient/command_reply.c.
1260 * Changed the channel message payload's MAC generation to
1261 include the IV in the MAC as well. This way all relevant
1262 parts of the channel message payload are authenticated also
1263 with the channel message MAC (and not only by packet MAC).
1264 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1265 Affected file is lib/silccore/silcchannel.c.
1267 * Fixed the SKE to save the remote version, since the
1268 silc_ske_parse_version mistakenly checked wrong version,
1269 after it replaced the start payload. Affected files are
1270 lib/silcske/silcske.[ch].
1272 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1275 string utility functions. Added there also new functions
1276 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1277 Affected files lib/silcutil/silcstrutil.[ch].
1279 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1280 files are lib/silcutil/silcstrutil.[ch].
1282 * Defined that the security property fields in SKE SHOULD be
1283 UTF-8 encoded, defined that version string MUST be US-ASCII
1284 encoded, defined that passphrases sent in connection
1285 authentication protocol MUST be UTF-8 encoded. Implemented
1286 these to the client and server. Defined also that other
1287 passphrases sent in the protocol MUST be UTF-8 encoded.
1288 Affected files are lib/silcske/silcske.c,
1289 lib/silcclient/protocol.c, silcd/protocol.c,
1290 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1292 * Changed the silc_client_close_connection interface to not
1293 need the SilcSocketConnection which should not be visible
1294 to application. Affected files are lib/silcclient/client.c
1295 and lib/silcclient/silcclient.h.
1297 * Rewrote the text for Private Message Key Payload in the
1298 protocol specification. Protocol TODO #11.
1300 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1302 * Upgraded the protocol version to 1.1, updated protocol specs
1305 * Added the nickname as new argument to NICK_CHANGE notify and
1306 added it to protocol specs and implemented it to client and
1307 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1308 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1309 lib/silcclient/client_notify.c.
1311 * Added the killer's client ID to the KILLED notify and added
1312 it to protocol specs and implemented it to client and server.
1313 Protocol TODO #13. Affected files are silcd/command.c,
1314 silcd/packet_receive.c, packet_send.[ch],
1315 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1316 The killer's client entry is now returned to application in
1317 the `notify' client operation.
1319 * Fixed the Max Argument fields that had too large value set
1320 in the protocol specs. Protocol TODO #14.
1322 * Added the LEAVE command reply to return the ID of parted
1323 channel. Updated protocol specs and implemented it to the
1324 client and server. Protocol TODO #15. Affected files are
1325 silcd/command.c, lib/silcclient/command_reply.c. The channel
1326 entry is now returned to application in the `command_reply'
1329 * Rewrote the version SKE version checking in client libary
1330 and in server to use the silc_parse_version_string. Affected
1331 files are lib/silcclient/protocol.c, silcd/protocol.c.
1333 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1334 commands that was missing it, and updated protocol specs and
1335 the server implementation. Protocol TODO #10. The affected
1336 file is silcd/command.c.
1338 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1339 generic reply to a generic request (REQUEST flag), and
1340 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1341 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1342 to define the payload for DATA flag. Added the flags to
1343 the implementation. Protocol TODO #9. Affected file is
1344 lib/silccore/silcchannel.h.
1346 Changed the client library to return the message length
1347 to application as well in the channel_message and private_message
1348 client operations. Affected files are
1349 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1350 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1351 and lib/silcclient/client_ops_example.c.
1353 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1354 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1355 the channel. Updated protocol specs and impelemented this
1356 to client and server. Protocol TODO #6. Affected files are
1357 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1358 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1360 Added new options m and M to CMODE command in Irssi SILC
1361 client to set these modes.
1363 * Deprecated all administrative commands from SILC protocol
1364 since they are highly implementation specific commands.
1365 Updated protocol specs. Moved the old commands in
1366 implementations to private range of command types. Affected
1367 files are silcd/command.c, lib/silcclient/command.c and
1368 lib/silcclient/command_reply.c. Protocol TODO #8.
1370 * Fixed a bug in server where sending unknown command crashes
1371 the server. Affected file silcd/command.c.
1373 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1375 * Added SILC_PROTOCOLVERSION macro to check protocol version
1376 of a socket connection. The affected file is
1377 lib/silcutil/silcsockconn.h.
1379 * Added better error logging in rekey protocol. Affected file
1382 * Do not check public key types in SKE during rekey. Affected
1383 file lib/silcske/payload.c.
1385 * Fixed the rekey protocol with PFS, which was totally broken.
1386 Affected file silcd/protocol.c.
1388 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1390 * Some client implementations quit network by doing first LEAVE
1391 and then immediately SIGNOFF (like Bombyx). We now do check
1392 after a short time after LEAVE notify and check whether the
1393 client is still valid after LEAVE, and if not we remove it from
1394 cache. Affected file is lib/silcclient/client_notify.c.
1396 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1398 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1399 it's good not to have security holes here.
1401 * Fixed a negative refcount situtuation for the config context.
1402 Affected file is silcd/serverconfig.c.
1404 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1406 * ROBOdoc documented lib/silcutil/silcutil.h.
1408 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1410 * Optimized even more the SilcPacketContext structure. Now
1411 totally saved 16 bytes of memory per context after optimization.
1412 Affected files are lib/silccore/silcpacket.[ch].
1414 * Made strict checks for valid SILC IDs. Affected file is
1415 lib/silccore/silcid.c.
1417 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Changed the object argument for silc_cipher_register,
1420 silc_hash_register, silc_hmac_register and silc_pkcs_register
1421 to const. Affected files are lib/silccrypt/silccipher.[ch],
1422 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1424 * Changed the silc_get_username and silc_get_real_name to
1425 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1427 * Fixed the Irssi SILC Client to use the silc_get_username and
1428 silc_get_real_name insted of glib routines since the glib
1429 routines only corrupt stack. Fixes the Irssi SILC to work in
1430 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1432 * Fixed the Irssi to not use g_get_home_dir since it crashes
1433 or returns garbage on cygwin and corrupts stack. Added function
1434 get_home_dir to Irssi routines. Affected files are
1435 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1437 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1439 * Made some structure optimizations. SFTP memory FS MemFSEntry
1440 entry structure. Optimized SilcTask structure. Optimized
1441 SilcPacketContext structure.
1443 Affected files lib/silcsftp/sftp_fs_memory.c,
1444 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1446 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1448 * And yet again reverted back the config thing since Johnny
1449 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1452 * Fixed memory leaks from config object. Affected files are
1453 silcd/serverconfig.[ch].
1455 * Added support for adding new connections to the server in rehash.
1456 After rehash they take effect.
1458 Added support for changing the maximum allowed connections in
1459 rehash. The number can grow but going smaller is not supported.
1461 Added function silc_server_num_sockets_by_remote to the
1462 silcd/server_util.[ch].
1464 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1466 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1468 * Added preliminary checking during config parsing for a valid
1469 public/private key and removed further checks in the code.
1470 Affected files are silcd/serverconfig.[ch], server.c.
1472 * Moved functions silc_server_drop() and silc_server_daemonise()
1473 from server.c to silcd.c since they are stricly related to
1474 the application activity.
1476 * Reverted a small part of the automatic ref/unref since
1477 it caused a double unref in some situations. Affected
1478 files are silcd/silcd.[ch], server.c, serverconfig.c.
1480 * Added some .cvsignore files in the lib directory.
1482 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1484 * Fixed silc_net_gethostbyaddr to correctly resolve by
1485 address. Affected file lib/silcutil/silcnet.c.
1487 * Fixed the notify relaying to client. The HMAC to be used
1488 with relayed packets ws wrong and caused decryption failure
1489 at the client end. Affected file is silcd/packet_receive.c.
1491 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1493 * Created new branch silc_protocol_1_0_branch.
1495 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1497 * Changed the silc_server_config_* routines to be SilcServer
1498 independent. They are now officially application specific code
1499 and not part of generic server implementation. Affected files
1500 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1502 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * Added automatic referencing of config context in the
1505 silc_server_config_alloc, and automatic unreferencing in the
1506 silc_server_config_destroy. Affected files are
1507 silcd/serverconfig.[ch], silcd/silcd.c.
1509 * Fixed the silc_log_quick handling in the logging routines.
1510 It didn't log quickly when it was TRUE. Affected file is
1511 lib/silcutil/silclog.c. Also the flush delay was set even
1512 if it was 0 in config file. Affected file is
1513 silcd/serverconfig.c.
1515 * Added support for changing key pair of the server in rehash.
1516 Affected file silcd/server.c.
1518 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1520 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1521 too early, before getting the channel entry. Affected file
1522 is silcd/packet_receive.c.
1524 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1526 * Added functions silc_server_config_[ref/unref], these are used
1527 to prevent that the config object is destroyed.
1529 No longer directly affect global variables silc_log_quick and
1530 silc_log_delay, they are first cached inside the config object
1531 and then applied with silc_server_config_setlogfiles().
1533 silc_server_config_set_defaults() is now internal to
1534 serverconfig.c, there are no reasons to show this internal stuff
1537 Affected files are silcd/serverconfig.[ch].
1539 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1540 fprintf's to stderr, since some code may be executed again after
1541 the server went into the background. Affected files are
1544 * Added rehash support. Added function silc_server_rehash() that
1545 will perform all the basic tasks of the rehashing procedure.
1547 * Added command line option `-x, --hexdump'. This will enable the
1548 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1549 The option `--hexdump' implies `--debug'.
1551 * Fixed a bad bug in the logging APIs (silcutil library) where
1552 the application would crash after calling silc_log_reset_all().
1554 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1556 * Fixed the KICKED notify handling in client library to
1557 correctly remove the channel and all entries from the
1558 channel when I was kicked. This bug crashed the client.
1560 Fixed yet another but in KICKED notify handling to remove
1561 the kicked client correctly from the channel.
1563 Affected file is lib/silcclient/client_notify.c.
1565 * Fixed a minor bug in looking up correct client entry
1566 in KICKED notify in server. Affected file is
1567 silcd/packet_receive.c.
1569 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1570 sources correctly to distribution. Fixes --with-gmp option.
1572 * Removed the manual rehashing from ID Cache, and changed it
1573 to use the SILC Hash Table's auto rehash feature. Affected
1574 file is lib/silccore/silcidcache.c.
1576 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1578 * Fixed a bug in the silc_client_nickname_format function that
1579 handles the multiple same nickname formatting. Two clients
1580 with same nickname caused problems after the first one left
1581 and rejoined. It didn't format the nickname correctly.
1582 Affected file is lib/silcclient/idlist.c.
1584 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Don't change the topic if olod topic is same as new one.
1587 Affected file is silcd/packet_receive.c.
1589 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1591 * Added cross-reference support to the SILC Documentation
1592 generator. All types across all HTML files are now cross-
1593 referenced. Affected files util/robodoc/generator.c and
1594 scripts/silcdoc/silcdoc.
1596 * Added file lib/silcutil/silctypes.h to include all the
1597 arithmetic type definitions and some macros. Removed
1598 includes/bitmove.h and moved macros to silctypes.h.
1600 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1602 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1604 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1606 * Added `type' argument to silc_id_payload_parse_id function which
1607 now returns the type of the ID to the sent pointer. Affected
1608 file is lib/silccore/silcid.[ch].
1610 * Added check for CMODE_CHANGE notify type that mode change is
1611 allowed by the sender. Affected file silcd/packet_receive.c.
1613 * Added check for CUMODE_CHANGE notify type that mode change is
1614 allowed by the sender. Affected file silcd/packet_receive.c.
1615 Added the ID type as CUMODE_CHANGE notify type as argument
1616 to the `notify' client operation. Affected files are
1617 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1619 * Added function silc_client_add_server to the client library.
1620 Added support for resolving also channel and server info when
1621 received unknown entity in notify packet. Affected files are
1622 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1624 * Added function silc_command_get_status to return the command
1625 status from the command reply's argument payload. Affected files
1626 are lib/silccore/silccommand.[ch].
1628 * Added check for KICKED notify type that the kicking is
1629 allowed by the client. Affected file silcd/packet_receive.c.
1631 * Created function silc_get_input which can be used to get input
1632 (echo on or off) from user on command line. Affected files are
1633 lib/silcutil/silcutil.[ch].
1635 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1637 * Optimized silc_server_packet_relay_to_channel function.
1638 Added new function silc_channel_message_payload_encrypt which
1639 can be called directly if channel message payload needs to
1640 be encrypted and is already encoded (no need to call _encode
1641 function). Packet relaying is now done by router without any
1642 extra memory allocations. Affected files are
1643 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1644 silcd/packet_send.c.
1646 * Fixed the INVITE notify handling. It took wrong arguments
1647 as invite list and invite delete. Affected file is
1648 silcd/packet_receive.c.
1650 * Added check for TOPIC_SET notify type that the topic change is
1651 allowed by the client. Affected file silcd/packet_receive.c.
1653 * Added check for INVITE notify type that inviting is allowed by
1654 the client. Affected file silcd/packet_receive.c.
1656 * Changed the silc_server_client_on_channel to return the
1657 SilcChannelClientEntry as well. Moved the function
1658 silc_server_check_cmode_rights to server_util.[ch].
1659 Affected files are silcd/server_util.[ch], silcd/command.c.
1661 * Added function silc_server_check_umode_rights to check whether
1662 changing client's user mode is allowed. Added check for
1663 UMODE_CHANGE notify type that the umode change is allowed
1664 by the client. Affected files are silcd/server_util.[ch],
1665 silcd/packet_receive.c and silcd/command.c.
1667 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1669 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1670 ID length. It ignored that ID can be IPv6 based as well.
1671 Affected file lib/silccore/silcpacket.h.
1673 * Fixed the silc_id_id2str and silc_id_str2id to take the
1674 IPv6 address offset's into consideration. Affecte file is
1675 lib/silccore/silcid.c.
1677 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1679 * Fixed the internal Unix scheduler functions to check for
1680 NULL context they may receive. The affected file is
1681 lib/silcutil/unix/silcunixschedule.c.
1683 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1685 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1686 can specify different directory with --home command line
1687 parameter. Affected files irssi/src/silc/core/client_ops.c,
1690 * SILC-specific commands aren't now executed if the active server
1691 isn't of SILC-type, so there won't be problems with having
1692 IRC and SILC protocol support in same client. Affected files
1693 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1696 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1698 * Improved the signal support in SILC Schedule. Added new
1699 function silc_schedule_signal_call which is used by application
1700 to mark a signal to be called. It is now safe to perform
1701 any kind of tasks in signal callbacks since it is guaranteed
1702 that the application specified signal callback is called
1703 after the signal is over. Affected files are
1704 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1706 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Added `name' field to SilcChannelPrivateKey to represent
1709 application given name for the key. Moved also the context from
1710 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1711 Added the `name' argument also to the function
1712 silc_client_add_channel_private_key.
1714 Added function silc_client_current_channel_private_key to set the
1715 current channel private key in use.
1717 Added "change" command to KEY command which can be used to change
1718 the current channel private key. Bound the command also to
1719 alt+K (Alt+Shift+k).
1721 Also affected files lib/silcclient/client_channel.c,
1722 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1724 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1726 * Added silc_rng_get_byte_fast function in to the
1727 lib/silccrypt/silcrng.[ch].
1729 * Changed the interface of silc_packet_assemble and the
1730 silc_packet_send_prepare. If silc_packet_assmble is now
1731 called the application does not call silc_packet_send_prepare
1732 because the library will call it automatically. These
1733 interfaces now also return a reference to the outgoing buffer
1734 which includes the assembled packet, which the application can
1735 use to encrypt the packet.
1737 Affected files are lib/silccore/silcpacket.[ch],
1738 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1739 silcd/packet_send.c, server_backup.c and packet_receive.c.
1741 * Fixed a packet sending bug on very high load, where outgoing
1742 packet queue wasn't handled correctly and packets got corrupted.
1743 Affected files are lib/silcutil/*/silc*sockconn.c,
1744 lib/silcclient/client.c and silcd/server.c.
1746 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1748 * Added macro SILC_PACKET_DATALEN which can be used during
1749 packet assembling to check whether the data to be added to
1750 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1751 len is truncated until it fits it.
1753 Added checks for maximum length of channel message payload and
1754 private message payload also.
1756 Added checks for maximum packet length in server and in
1759 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1760 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1761 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1762 lib/silcclient/client_prvmsg.c.
1764 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1766 * Added silc_server_packet_queue_purge call to the
1767 silc_server_disconnect_remote to assure that all data in the
1768 queue before disconnecting is sent to the network. Affected
1769 file silcd/server.c.
1771 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1773 * Added the deleting of server's own ID cache entry to the
1774 silc_server_free function. Free also everything else that
1775 has been allocated in silc_server_init. The affected file
1778 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1780 * Added functions silc_parse_version_string, silc_version_to_num,
1781 and silc_ske_parse_version to parse SILC protocol style version
1782 strings. Affected files lib/silcutil/silcutil.[ch] and
1783 lib/silcske/silcske.[ch].
1785 * Added new configuration params: version_protocol, version_software
1786 and version_software_vendor to specify what version the remote
1787 host must at least be to be able to connect to server. The vendor
1788 string can be regex matched too. Added new function
1789 silc_server_connection_allowed to check maximum number of allowed
1790 connections, and allowed versions for incoming connections.
1791 Affected files are silcd/server.c, server_util.[ch] and
1794 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1796 * Added preliminary support for signals in scheduler. The
1797 signals we care about are now blocked always when the scheduler
1798 is locked. This way we can synchronise the use of signal with
1799 scheduler. It is guaranteed that when signal occurs the scheduler
1800 is not locked, and thus new tasks can be safely added to the
1803 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1804 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1805 Added new platform specific routines
1806 silc_schedule_internal_signals_[un]block and
1807 silc_schedule_internal_signal_[un]register.
1809 Added new functions to SILC Schedule API:
1810 silc_schedule_signal_[un]register. Each signal that application
1811 is going to use should be registered to the scheduler.
1813 Affected files are lib/silcutil/silcschedule.[ch],
1814 lib/silcutil/*/silc*schedule.c.
1816 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1818 * Check for unauthenticated client and server in the
1819 silc_server_new_client and silc_server_new_server functions.
1820 Affected file silcd/packet_receive.c.
1822 * Added function silc_string_is_ascii to check whether given
1823 string is 7-bit ASCII string. Affected files are
1824 lib/silcutil/silcutil.[ch].
1826 * Added function silc_id_is_valid_server_id into the
1827 silcd/serverid.c and added checking for valid Server ID's in
1828 silc_server_new_server. The Server ID must always be based
1829 on the server's public IP address.
1831 * Added logging of DISCONNECT packet message in the server.
1832 Affected file silcd/server.c.
1834 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1836 * Changed all library interfaces that use Global RNG to also
1837 accept SilcRng as argument. Affected files are
1838 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1839 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1840 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1841 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1842 lib/silccrypt/rsa.c.
1844 * Added function silc_pkcs_generate_key to the
1845 lib/silccrypt/silcpkcs.[ch] for applications so that they
1846 don't need to do pkcs->pkcs->init calls anymore.
1848 * Remove SilcSocketConnection from the SFTP API since it really
1849 wasn't needed there. The application has the information
1850 saved in its contexts anyway and the SFTP layer doesn't need
1851 know about it. Affected files lib/silcsft/silcsftp.h and
1852 lib/silcsftp/sftp_[server/client].c.
1854 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1855 The SilcSimContext is not SilcSim.
1857 * Fixed possible buffer overflows in silc_id_render in the
1858 lib/silcutil/silcutil.c.
1860 * On EPOC the global crypto module lists are not used at all
1861 in the crypto library. Added support for using the constant
1862 algorithm list on EPOC. Affected files are
1863 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1866 * Fixed the handling of third parameter of KICKED notify, since
1867 it was mistakenly updated to SILC Protocol 1.0 even though it
1868 is to be included in 1.1. Since it is not in 1.0 it is not
1869 mandatory, and this fix now handles it only if it is provided,
1870 and it is not error if it is not provided. Affected file
1871 lib/silcclient/client_notify.c.
1873 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1875 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1876 client. Affected file irssi/src/silc/core/client_ops.c.
1878 * Merged with Irssi 0.8.4 from irssi.org CVS.
1880 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1882 * Check for valid socket connection in client entries before
1883 sending any messages. Fixes a crash, but doesn't fix some
1884 other underlaying bug that is lurking there. Affected
1885 file silcd/packet_send.c.
1887 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1889 * $usermode, $cumode and $cumode_space expandos shouldn't do
1890 anything with non-SILC server records. Affected file
1891 irssi/src/silc/core/silc-expandos.c
1893 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1895 * Fixed the silc_net_check_[host/local]_by_sock to support
1896 IPv6 bound sockets as well. Now they can return IPv6 addresses
1897 as well. Affected file lib/silcutil/silcnet.c.
1899 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1900 Affected lib/silcutil/unix/silcunixnet.c.
1902 * Fixed ID rendering (at least on some platforms, not NetBSD)
1903 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1905 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1907 * Added silc_hash_public_key and silc_hash_public_key_compare
1908 functions to be used with SilcHashTable. They can be used to
1909 hash public keys and compare public keys in hash table. Affected
1910 file lib/silcutil/silcutil.[ch].
1912 * Added support for specifying multiple public keys for Client
1913 connection section in server configuration file. This makes it
1914 possible to accept multiple public keys from same host, or to
1915 make a section that accepts any incoming host, and have the
1916 accepted public keys listed in the section.
1918 Added functions silc_sever_[find/get]_public_key, added the
1919 support for this actually to all connection sections but only
1920 the Client section is currently allowed to specify multiple
1923 Affected files are silcd/server.c, server_internal.h,
1924 command.c, protocol.c, server_util.[ch], packet_receive.c.
1926 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1928 * Merged Irssi 0.8.2 from irssi.org CVS.
1930 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1932 * If silc_debug is TRUE, also output standard logging messages
1933 to stderr with the debug output.
1935 Made silc_log_reset_all() flushing all channels before returning.
1936 Also fixed some documentation typos.
1938 Affected files are lib/silcutil/silclog.[ch].
1940 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1942 * Fixed the server to check correctly the amount of connections
1943 from single host, by checking also the type of the connection.
1944 Fixed also the comparison of number of connections and number
1945 of allowed connections. Affected files are silcd/server.c,
1948 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1950 * Fixed the USERS command reply to save the user's mode on the
1951 channel as well. Fixed JOIN command reply to check whether a
1952 client is on channel already and not join it twice. Affected
1953 file lib/silcclient/command_reply.c.
1955 * Added new file silc-expandos.c into irssi/silc/core/ to return
1956 various stuff for various signal for the statusbar etc. updating.
1957 Now Irssi SILC client prints channel user modes etc. on the
1960 * The user mode (like server/router operator changes) is now shown
1961 on the Irssi SILC client's statusbar. The affected files are
1962 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1964 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1966 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1967 to SILC_SCHEDULE_[UN]LOCK macros.
1969 * Added more error printing to logs in server code. Affected
1970 files silcd/server.c and silcd/protocol.c.
1972 * Fixed -S option parsing in Irssi SILC Client. Affected file
1973 irssi/src/silc/core/silc-core.c.
1975 * Added silc_buffer_alloc_size function. Affected file is
1976 lib/silcutil/silcbuffer.h.
1978 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1980 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1981 constants. Affected files in
1982 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1985 * Changed the internal SFTP Memory FS table to const. Affected
1986 file lib/silcsftp/sftp_fs_memory.c.
1988 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1990 * Fixed the buffer formatting and unformatting routines to
1991 check the size of 64 bits types with sizeof(). Affected
1992 file is lib/silcutil/silcbuffmt.c.
1994 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1996 * Removed 0.6.x backwards support.
1998 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2000 * Changed all integer type names:
2001 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
2002 to avoid collisions with other libraries using same type names
2005 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2007 * Added `prefer_ipv6' argument to the functions
2008 silc_net_gethostbyname[_async]. If it is TRUE it will return
2009 IPv6 address over IPv4. If FALSE IPv4 address is returned
2010 even if IPv6 address was found. Affected files
2011 lib/silcutil/silcnet.[ch].
2013 * Added support silc_net_create_connection[_async] to fallback
2014 to IPv4 address if IPv6 address could not be used (like if
2015 it doesn't work on a specific system). Affected file in
2016 lib/silcutil/unix/silcunixnet.c.
2018 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2020 * Added silc_schedule_reinit function to do the enlarging
2021 of the max tasks handling capabilities of the scheduler.
2022 Affected files lib/silcutil/silcschedule.[ch].
2024 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2026 * Added automatic extern "C" { ... } for C++ compilers so the
2027 application does not need to define them. Affected file
2028 includes/silcincludes.h.
2030 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2031 old name went against naming convention. Applications now
2032 include "silcclient.h" instead of "clientlibincludes.h".
2033 Removed includes/clientlibincludes.h, it is redundant now.
2035 * Renamed includes/version.h to silcversion.h.
2037 * Added really preliminary support for OS/2 into the util
2038 library. Only thread & mutex API is implemented, others
2039 are still to be implemented. Created the lib/silcutil/os2/
2040 directory. Created also file includes/silcos2.h.
2042 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2044 * Added preliminary BeOS support into the util library.
2045 Created lib/silcutil/beos/, and implemented all the needed
2046 functions to support SILC on BeOS. Created also file
2047 includes/silcbeos.h.
2049 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
2051 * Added proper initializations to silc's irssi code, so it's
2052 now possible to load it as module. Affected files
2053 irssi/src/silc/core/silc-core.c,
2054 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
2056 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2058 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
2061 * Fixed the silcdoc document generator to correct generate
2062 docs from all kinds of filenames. Affected files are
2063 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
2065 * ROBOdoc documented lib/silcutil/silcmemory.h.
2066 Added also new function silc_memdup.
2068 * Removed lib/silcutil/silcbufutil.h and moved those routines
2069 to the lib/silcutil/silcbuffer.h.
2071 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2073 * Added `user_count' to the SilcChannelEntry which now tells the
2074 number of users on the channel. The user count is now saved
2075 in normal server of global channels as well. Affected files
2076 silcd/server.c, idlist.h, packet_receive.c and command.c.
2078 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2079 include file utility functions.
2081 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2082 instead of calling directly OS routines.
2084 * Fixed NICK change printing in Irssi SILC Client. Fixed
2085 KICKED notify printing in Irssi SILC Client. Affected file
2086 irssi/src/silc/core/client_ops.c.

2094 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2095 the SKE interface a bit.
2097 * Fixed padding problem in PKCS#1. The padding was not actually
2098 random since the random number generator was used incorrectly.
2099 This security bug affects only when encrypting with PKCS#1, and
2100 it is not currently used at all in SILC. SILC only use signing
2101 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2114 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
2115 key_exchange_timeout, conn_auth_timeout, connections_max,
2118 Implemented all the new config settings handling in the server.
2120 Optimized the use of SKE Mutual flag usage. Use it only
2121 if connection authentication protocol is not based in public
2124 Renamed all SilcServerConfigSection* to SilcServerConfig*
2125 to have a bit shorter names.
2127 Affected files silcd/serverconfig.[ch], server.[ch], and

2156 Affected files are silcd/serverconfig.[ch].
2158 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2160 * Fixed command line parameter handling. All SILC initialization
2161 is now done in silc_core_init() which also fixes autoconnecting
2164 Affected files irssi/src/silc/core/silc-core.c,
2165 irssi/src/fe-text/silc.c.
2167 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2169 * Added new configuration options and blocks:
2170 keepalive_secs, reconnect_count, reconnect_interval,
2171 reconnect_interval_max, reconnect_keep_trying and
2172 require_reverser_lookup. Added ConnectionParam block, and
2173 implemented the connection parameters when connecting as
2174 initiator and when accepting connections as responder.

2186 the connection configuration object from the SilcServerConnection
2187 object instead of finding it during the connecting phase.
2188 Added the configuration object to SilcServerConnection struct.
2189 Affected files silcd/server_internal.h, server.c.
2191 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2193 * Add the client on channel after it was resolved at the
2194 channel message receiving, and it was not already on the
2195 channel. Affected file lib/silcclient/client_channel.c.
2197 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2211 * Added new Passphrase and Publickey authentication methods to
2212 config file, allowing both public key and passphrase based
2213 authentication to be set at the same time.
2215 Added `prefer_passphrase_auth' setting in config file which
2216 can be used to set to prefer passwd auth if both passwd and
2217 public key is set. If not set, public key is preferred.
2218 This has effect only when being initiator (responder will try
2221 Added support for authentication with passphrase and public key
2222 at the same time. The passphrase is tried first always since
2223 it is faster to check.
2225 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2227 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2229 * Merged the new SILC Config library, with the server parsing

2256 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2257 as header filenames.
2259 * Removed lib/silcclient/README and created HTML file
2260 lib/silcclient/silcclient_using.html, which is now included
2261 as part of Toolkit documentation.
2263 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2265 * Fixed CUMODE_CHANGE notify handling to change the mode of
2266 correct client. Affected file lib/silcclient/client_notify.c.
2268 * Make silc_rng_alloc fail if it cannot allocate the sha1
2269 hash algorithm. Affected file lib/silccrypt/silcrng.c.

2273 * Fixed the file transfer's key agreement payload to include
2274 zero port also if the hostname is NULL because it could not
2277 Call file transfer monitor callback now also if error occurs
2278 during key agreement protocol.
2280 Changed the silc_client_file_send interface to return the
2281 SilcClientFileError instead of session id. The session ID
2282 is returned into pointer provided as argument.
2284 Check that the file exists locally before sending the
2285 file transfer request at all.
2287 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2289 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2290 error than can occur while key agreement protocol. Affected
2291 file lib/silcclient/silcapi.h.

2294 is changed and +k mode is set in the channel. Affected file
2295 irssi/src/silc/core/silc-channels.c.
2297 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2298 SILC_LOG_WARNING to give out Warning and not Error. Affected
2299 file lib/silcutil/silclog.c.
2301 * Fixed the channel message payload decryption in the function
2302 silc_channel_message_payload_decrypt to not modify the original
2303 buffer before it is verified that the message decrypted
2304 correctly. Otherwise, next time it is called with correct
2305 channel key it won't encrypt since the payload is corrupted.
2306 Affected file lib/silccore/silcchannel.c.
2308 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2320 * Fixed a bug in hash table internal routine for traversing
2321 the table with foreach callback. The current entry may
2322 become invalid in the callback but it was referenced after
2323 the callback returned.
2325 Do not allow auto rehashing of hash table during the
2326 silc_hash_table_foreach operation, for same reasons as it is
2327 not allowed for SilcHashTableList. Affected files are
2328 lib/silcutil/silchashtable.[ch].
2330 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2332 * Defined DLLAPI into silcincludes.h and silcwin32.h for

2336 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2338 * Fixed private message handling. It used some old code that
2339 caused the client to crash. Affecte file is
2340 lib/silcclient/client_prvmsg.c.
2342 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2344 * Added function silc_client_add_channel,
2345 silc_client_replace_channel_id, and removed functions
2346 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2347 from client library.
2349 * Added cross reference of the joined channels to the
2350 SilcClientEntry, and changed the SilcChannelEntry's
2351 users list to SilcHashTable. The affected files are
2352 lib/silcclient/idlist.[ch].
2354 * Fixed a bug in hash table tarversing. While the hash table
2355 is traversed with SilcHashTableList the table must not be
2356 rehashed. It is now guaranteed that auto rehashable tables
2357 are not rehashed while tarversing the list. Also defined that
2358 silc_hash_table_rehash must not be called while tarversing
2359 the table. Added function silc_hash_table_list_reset that must
2360 be called after the tarversing is over. The affected files are
2361 lib/silcutil/silchashtable.[ch].
2363 * Changed all hash table traversing to call the new
2364 silc_hash_table_list_reset in server and in client library.
2366 * Added function silc_client_on_channel to return the
2367 SilcChannelUser entry if the specified client entry is joined
2368 on the specified channel. This is exported to application as
2369 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2371 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2373 * Fixed founder regaining problem with JOIN command on normal
2374 server. The notify for mode change must be sent always and
2375 not only if !cmd->pending. Affected file silcd/command.c.
2377 * Fixed the WHOWAS command's reply sending to support the
2378 lists correctly. Affected file silcd/command.c.
2380 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2382 * When sending JOIN command to router for processing the
2383 sender's old command identifier was not saved back to the
2384 sender's command context, fixed now. The affected file is
2387 * Create the key in JOIN command of the router did not return
2388 the channel key, added check for this. Affected file is
2391 * Fixed a channel ID update bug in JOIN command reply. Do
2392 not directly upgrade the ID but call the function
2393 silc_idlist_replace_channel_id if the ID was changed.
2394 Affected file silcd/command_reply.c.
2396 * Fixed memory leaks from command calling if it would fail.
2397 Affected file silcd/command.c.
2399 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2409 * Removed TRQ from lib/trq, not needed anymore.
2411 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2412 with server connections. Later this will be configurable
2413 in config file after new config file is done. Affected file
2416 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2418 * Fixed a crash in server related to channel announcements.
2419 Affected file silcd/server.c.
2421 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2423 * Fixed memory leaks in silc_server_create_new_channel*
2424 functions. Affected file silcd/server.c.
2426 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2427 which ID was changed. This way the router will send the
2428 user list for the channel again, and server won't be in
2429 desync in some rare circumstances. Affected file is
2430 silcd/packet_receive.c.
2432 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2434 * Check for NULL socket pointer in the function

2444 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2446 * Added lib/silcclient/client_ops_example.h as an template
2447 file for application programmers to quickly start using
2448 the SilcClientOperation functions in their application.
2449 Updated the lib/silcclient/README as well to tell about this
2450 nice file made available.
2452 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2454 * Call silc_server_remove_from_channels when removing client
2455 entry when NO_SUCH_CLIENT_ID was received. Affected file
2456 is silcd/command_reply.c.
2458 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2460 * Added server & router operator statistics updating. Affected
2461 file silcd/packet_receive.c and silcd/command.c.
2463 * Fixed the SERVER_SIGNOFF notify handling on normal server
2464 not to save the history information for clients. Same was
2465 fixed earlier in remove_clients_by_server function, but not
2466 here. Affected file silcd/packet_receive.c.
2468 * Raised the default connection-retry count from 4 to 7 in
2469 server. Affected file silcd/server.h.
2471 * Cancel any possible reconnect timeouts when we start the
2472 key exchange. Affected file silcd/server.c.
2474 * Do not reconnect on connection failure when SCONNECT was
2475 given. Affected files silcd/server.[ch].
2477 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2479 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2481 * Fixed the NICK command to always give the unformatted
2482 nickname to the one giving the NICK command. If unformatted
2483 nickname is cached already it will be formatted and the
2484 local entry will always get the unformatted nickname.
2485 Affected file lib/silcclient/idlist.c.
2487 * Fixed some double frees from client library commands.
2488 Affected file is lib/silcclient/command.c.
2490 * Fixed CUMODE command in server to assure that no one can
2491 change founder's mode than the founder itself, there was a
2492 little bug. Affected file silcd/command.c.
2494 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2496 * Removed the SilcClientCommandDestructor from the client
2497 libary, it is not needed anymore. Affected files are
2498 lib/silcclient/silcapi.h, command[_reply].[ch],
2499 client_notify, idlist.c.
2501 * Fixed GETKEY command to first resolve client, and then
2502 resolve the server only if the client was not found, instead
2503 of resolving both at the same time. Affected file is
2504 lib/silcclient/command.c.
2506 * Added silc_client_start_key_exchange_cb and lookup the
2507 remote hostname and IP address before starting the key
2508 exchange with server. The affected file is
2509 lib/silcclient/client.c.
2511 * The server's public key is now saved using the IP address
2512 of the server and not the servername for the filename.
2513 The hostname public key filename is checked as an fall back
2514 method if the IP address based filename is not found.
2516 Fixed the GETKEY command to save the fetched server key
2517 in correct filename.
2519 Print the remote server's hostname now when new key is
2520 received during connection process. Affected file is
2521 irssi/src/silc/core/client_ops.c.
2523 * Return always our own public key to the client if it asks
2524 for it with GETKEY command. Affected file silcd/command.c.
2526 * Removed the use_auto_addr variable from default config
2527 file since it was in wrong section. Affected file is
2530 * Fixed TOPIC_CHANGE notification to not route it when it
2531 was sent using silc_server_send_notify_to_channel function.
2532 Affected file silcd/command.c.
2534 * Fixed silc_server_send_notify_kicked to send the kicker's
2535 Client ID also, it was missing. Affected files are
2536 silcd/command.c, silcd/packet_send.[ch].
2538 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2540 * Do not save client history information in SERVER_SIGNOFF.
2541 Fixes the bug in normal server that it does not detect
2542 the client becoming valid after the server becomes back
2543 online. Affected file silcd/server_util.c.
2545 * Added `sock_error' field into the SilcSocketConnection
2546 context. When error occurs during socket operation (read
2547 or write) the error is saved. Added also new function
2548 silc_socket_get_error to return human readable socket error
2549 message. Affected files are lib/silcutil/silcsockconn.[ch],
2550 lib/silcutil/unix/silcunixsockconn.c, and
2551 lib/silcutil/win32/silcwin32sockconn.c.
2553 * The server now prints the socket error message in the
2554 signoff for client. Affected file silcd/server.c.
2556 * Fixed the `created' channel information sending from router
2557 to server in JOIN command. Checks now whether the channel
2558 really was created or not and set it according that.
2560 Fixed the JOIN command to use the client entry's current
2561 ID during the joining procedure instead of the one it sent
2562 in the command (it is checked though), since it can change
2563 between the packet processing and command processing, and
2564 would just case unnecessary pain in the client end. Affected
2565 file silcd/command.c.
2567 * Fixed a channel key payload sending to use correct channel
2568 ID when the server was forced to change the channel's ID by
2569 router. Router sent the key payload with the old Channel ID.
2570 Affected file silcd/packet_receive.c.
2572 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2574 * Call silc_server_save_channel_key only if the key payload
2575 was provided in the JOIN command's command reply. Affected
2576 file silcd/command_reply.c.
2578 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2580 * Fixed silc_mp_sizeinbase to return the value correctly with
2581 MPI. Affected file lib/silcmath/mp_mpi.c.
2583 * Fixed the stop_server signal to correctly stop the scheduler
2584 and gracefully stop the server when SIGTERM or SIGINT signals
2585 are received. Affected file silcd/silcd.c.
2587 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2589 * Simple handling of TERM and HUP signals. Also added some log
2590 flushing call around. Affected file is
2593 * Fixed small bugs in silclog.c. Now buffering output will take
2594 effect after 10 seconds since startup: This will ensure that
2595 no important startup messages are lost. Also output redirection
2596 will preserve original format ([Date] [Type] message).
2597 Affected file is lib/silcutil/silclog.c.
2599 * Added two options to the config file, in the logging section:
2600 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2601 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2603 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2605 * Do not print the warning about log files not being initialized
2606 more than once to avoid excess logging. Affected file is
2607 lib/silcutil/silclog.c.
2609 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2610 the SIM copying in make install in Makefile.am.pre.
2612 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2614 * Rewritten silclog APIs. Globally interesting changes follows:
2615 silc_log_set_files() changed to silc_log_set_file().
2616 silc_log_set_callbacks() changed to silc_log_set_callback().
2617 ROBOdoc documented silclog header file.
2618 SilcLogCb now returns bool to wether inihibit the default
2619 handler or not (to keep the old behaviour return always TRUE).
2620 The new APIs should also fix the problem of the
2621 silcd_error.log file that was written in the current directory.
2624 Log files streams will remain opened after silc_log_set_file()
2625 call, means less CPU usage notably on high traffic servers.
2626 File streams are now full buffered, and flushed to the disk
2627 every 5 minutes, lesses HD activity and CPU usage.
2628 Messages can be redirected, allowing admins to configure
2629 one single logfile for all server messages.
2630 the silc_log_quick global variable to activate fast-logging.
2631 Affected files lib/silcutil/silclog.[ch]
2633 * Changed some code to conform new silclog APIs. Affected
2634 files are doc/example_silcd.conf.in, silcd/server.c
2635 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2638 * Fixed a memory leak that could occur in some situations.
2639 Affected file silcd/serverconfig.c.
2641 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2643 * Added the silc_client_del_client to remove the client from
2644 all channels as well. Affected file lib/silcclient/idlist.c.
2646 * Fixed the client library to correctly remove the client
2647 from all channels when the client entry is being destroyed.
2648 Affected file lib/silcclient/client_notify.c, command.c.
2650 * Added auto-nicking support to the client library. If the
2651 applicatio now sets client->nickname it will be sent to the
2652 server after connecting by the library. This way for example
2653 SILCNICK (or IRCNICK) environment variables will have effect
2654 and always change the nickname automatically to whatever
2655 it is wanted. Affected file lib/silcclient/client.[ch].
2657 * Renamed silc_server_command_bad_chars to the
2658 silc_server_name_bad_chars and moved it to the
2659 silcd/server_util.[ch]. Added also new function
2660 silc_server_name_modify_bad to return nickname that
2661 includes bad characters as new nickname without those
2662 bad characters. This check and modify is now used in
2663 silc_server_new_client when the username is initially set
2664 as nickname, so it must be checked to be valid nickname.
2665 Affected file silcd/packet_receive.c.
2667 * The nickname length is now taken from the packet for real
2668 and not trusted to strlen() since it clearly can return
2669 wrong length for nickname including bad characters. This
2670 also applies to channel names. Affected file silcd/command.c.
2672 * Removed the lib/silcsilm/modules directory. Modules are now
2673 compiled into the lib/silcsim. Fixed the copying of the
2674 modules to follow symbolic links in Makefile.am.pre.
2676 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2678 * Fixed silc_string_regexify list creation. Fixes bugs with
2679 BAN and INVITE commands in server. The affected file is
2680 lib/silcutil/unix/silcunixutil.c.
2682 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Removed the command destructor entirely from the server's
2685 command and command reply routines. It is not needed, and
2686 its usage was buggy and caused crashes. Affected files are
2687 silcd/command[_reply].[ch].
2689 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Cancel protocol and NULL sock->protocol if timeout
2692 occurred during protocol. Affected file silcd/server.c.
2694 * Cancel protocol timeouts always before calling the final
2695 callback, to assure that after final callback is called
2696 no other state will be called for the protocol anymore.
2697 Affected file silcd/protocol.c.
2699 * Print error log if incoming connection configuration could
2700 not be found. Affected file silcd/server.c.
2702 * Fixed JOIN command to correctly save the founder mode
2703 to the client on normal SILC server, when the channel
2704 was created by the router. Affected file silcd/command.c.
2706 * Fixed LIST command (hopefully) to send correct reply
2707 packets. Affected file silcd/command.c.
2709 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * The silc_packet_receive_process now returns FALSE if the
2712 read data was invalid packet, and TRUE if it was ok.
2714 The server now checks that if unauthenticated connection
2715 sends data and its processing fails the server will close
2716 the connection since it could be a malicious flooder.
2718 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2720 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * Make sure the warning about error opening a log file is
2723 printed only once and not everytime it fails (produces
2724 too much useless log). Affected file lib/silcutil/silclog.c.
2726 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2728 * Made the silc_server_daemonise() function more readable.
2729 Affected file silcd/server.c.
2731 * Pid file is now optional, the user may comment it out from
2732 the config file. Removed define SILC_SERVER_PID_FILE, we
2733 don't need a default any longer. Affected file
2734 configure.in.pre, lib/Makefile.am.pre.
2736 * Make some use of the pid file. The server now dies at startup
2737 if it detects a valid pid file on his path. The server would
2738 die anyway in this circumstance, because of the bind() failure.
2739 Affected file silcd/silcd.c.
2741 * No longer compiling lib/dotconf.
2743 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2745 * Fixed JOIN command parsing not to crash. Affected file
2746 lib/silcclient/command.c.
2748 * Fied the NICK_CHANGE notify to add the new client entry
2749 even it is resolved. This removes an <[unknown]> nick
2750 thingy bug in the client. Affected file is
2751 lib/silcclient/client_notify.c.
2753 * Do not try to allocate 0 bytes (efence does not like it)
2754 in lib/silccore/silccomand.c when encoding payload.
2756 * Do not take IRCNICK as nickname in Irssi SILC client since
2757 it is not possible to set nickname before hand connecting
2758 the server (TODO has an entry about adding auto-nicking
2761 * Changed the silc_server_command_pending to check whether
2762 there already exists an pending entry with the specified
2763 command, command identifier and pending callback. This is
2764 to fix IDENTIFY and WHOIS related crashes that may register
2765 multiple pending commands with same identifier. Affected
2766 file silcd/command.c.
2768 * Fixed the server to reconnect to the router even if it
2769 was already reconnecting and EOF was received. This to
2770 fix a possibility that the server wouldn't ever try to
2771 auto-reconnect to the router. Affected file silcd/server.c.
2773 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2775 * Fixed the server's password authentication to use the
2776 length of the locally saved password, and not the one
2777 sent in the packet. Affected file silcd/protocol.c.
2779 * Fixed same password authentication problem in the
2780 Authentication Payload handling routines in
2781 lib/silccore/silcauth.c.
2783 * Yet another password authentication problem fixed with
2784 channel password handling in silcd/command.c.
2786 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * If first character of string in silc_parse_userfqdn is '@'
2789 then do not parse it. Affected file is
2790 lib/silcutil/silcutil.c.
2792 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Fixed minor bug in IDENTIFY command reply sending, which
2795 caused various weird problems during JOIN when it was
2796 resolving names for users. Affected file silcd/command.c.
2798 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Fixed the IDENTIFY command reply sending to chech better valid
2801 clients. It was possible to send incomplete list of replies.
2802 Affected file silcd/command.c.
2804 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2806 * Added silc_client_command[s]_[un]register functions now to
2807 dynamically register the commands in client library. Removed
2808 the static table of commands. This allows the client library
2809 to call commands without causing the application to know about
2810 what commands library has called.
2812 Removed the INFO command reply kludge to detect when the command
2813 was called by library. Now library use its own command reply
2814 function for INFO command.
2816 Added function silc_client_command_call to call a command.
2817 Application can use it to call command, not access the structure
2820 Now all commands that are sent by the client library (not
2821 explicitly sent by application) use own command reply functions.
2823 Affected files around lib/silcclient/ and in
2824 irssi/src/silc/core/.
2826 * Fixed the WHOIS command reply sending to chech better valid
2827 clients. It was possible to send incomplete list of replies.
2829 Fixed the WHOIS and IDENTIFY to send the request to router
2830 if normal server did not do it and did not find any results.
2832 Affected file silcd/command.c.
2834 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Moved the internal data from SilcClient context into its
2837 own file, not accesible to application. Affected files
2838 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2839 and other files in client library.
2841 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Added doc/examples installation target in Makefile.am.pre.
2846 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2849 commands the found client entry will be removed from the
2850 cache, after notifying application about the error. Affected
2851 file lib/silcclient/command_reply.c.
2853 * Changed the /MSG to check for exact nickname user gave, and
2854 not let `nick' match `nick@host' if it is only one found. Now,
2855 user must type the exact nickname (like nick@host2) even if
2856 there are no more than one same nicks found. This is to avoid
2857 a possibility of sending nickname to wrong nickname since
2858 `nick' could match `nick@host'. Affected file is
2859 irssi/src/core/silc-servers.c.
2861 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Do not print "you are now server operator" or similar when
2864 giving /away command. Affected files are
2865 irssi/src/silc/core/client_ops.c, silc-servers.h.
2867 * Made the silc_server_command_pending_error_check to send
2868 the same command reply payload it received back to the
2869 original sender of the command. This way all arguments
2870 that was received by the server will be received by the
2871 client too. Affected file silcd/command.c.
2873 * Added the silc_idcache_add to return the created cache entry
2874 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2876 * Add global clients to expire if they are not on any channel.
2877 This is because normal server will never know if they signoff
2878 if they are not on any channel. The cache expiry will take
2879 case of these entries. This is done by normal servers only.
2880 The affected files are silcd/command_reply.c,
2881 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2883 * If server receives invalid ID notification for WHOIS or
2884 IDENTIFY and the ID exists in the lists, it is removed.
2885 Affected file silcd/command_reply.c.
2887 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2888 in client then client entry that it matches is searched and
2889 the nickname is printed on the screen for user. Affected
2890 file irssi/src/silc/core/client_ops.c.
2892 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * Use cache entry expire time in the LIST command reply to
2895 purge old entries from the cache after the LIST command
2896 reply has been received. This way we don't have non-existent
2897 entries in the cache for too long. Affected file is
2898 silcd/command_reply.c.
2900 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * If we are normal server, and we've not resolved client info
2903 in WHOIS or IDENTIFY from router, and it is global client,
2904 we'll check whether it is on some channel. If it is not
2905 then we cannot be sure about its validity and will resolve it
2906 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2907 file silcd/command.c.
2909 * Search channel by name (if possible) rather than by ID
2910 in IDENTIFY command's command reply. Affected file is
2911 silcd/command_reply.c.
2913 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2916 Updated specs and implemented it. Affected file silcd/command.c,
2917 silcd/packet_send.c and silcd/packet_receive.c.
2919 * Implemented the <founder auth> payload handling in the JOIN
2920 command. If provided all conditions for channel joining
2921 except requirement to provide correct passphrase can be
2922 overrided by the channel founder. Updated the protocol specs.
2923 Affected file silcd/command.c.
2925 Added support for founder auth in JOIN command in client
2926 library. Fixed the parsing of the JOIN command now to support
2927 all options as they should be. The affected file is
2928 lib/silcclient/command.c.
2930 * Optimized the WHOIS and IDENTIFY commands to send the request
2931 to router only if it includes nicknames or other names. If
2932 they include only IDs then check the local cache first before
2933 routing. Affected file is silcd/command.c.
2935 * Added channels topic announcements. Affected file is
2936 silcd/packet_receive.c and silcd/server.c.
2938 * Fixed the silc_server_send_notify_topic_set to really destine
2939 the packet to channel. Affected file silcd/packet_send.c.
2941 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2942 library. Affected file lib/silcclient/client_notify.c.
2944 * Added UMODE announcements. Affected file silcd/server.c.
2946 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Memory leak fixes in:
2950 lib/silcutil/silcsockconn.c
2951 lib/silcske/silcske.c
2952 lib/silcske/groups.c
2954 lib/silccrypt/silcpkcs.c
2955 lib/silccore/silccommand.c
2956 lib/silccore/silcidcache.c
2961 * ROBOdoc documented the lib/silcske/groups.h file and a
2962 bit changed the interface for better.
2964 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2966 * Update the client entry context in the ID cache after
2967 nick change. Affected file lib/silcclient/command.c.
2968 Fixes the CUMODE command when regaining founder privileges,
2969 and a little WHOIS problem.
2971 * Fixed silc_net_gethostbyname to correctly call the
2972 inet_ntop. Affected file lib/silcutil/silcnet.c.
2974 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2976 * Added IPv6 support checking to the configure.in.pre, added
2977 also --enable-ipv6 option to override the check. Affected
2978 file configure.in.pre.
2980 * The silc_thread_create now calls the start function
2981 directly if threads support is not compiled in. Removes
2982 ugly #ifdef's from generic code. Affected files are
2983 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2985 * Added silc_net_gethostby[name/addr]_async to asynchronously
2986 resolve. Affected files are lib/silcutil/silcnet.[ch].
2988 * Added support for rendering IPv6 based server, client and
2989 channel IDs. Affected file lib/silcutil/silcutil.c.
2991 * Added support for creating IPv6 based server IDs. Affected
2992 file is silcd/serverid.c.
2994 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2996 * Added silc_net_gethostby[addr/name] into the
2997 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2998 routines. Added silc_net_is_ip[4/6]. Affected file is
2999 lib/silcutil/unix/silcunixnet.c. All routines that take
3000 address as argument now supports both IPv4 and IPv6 addresses.
3002 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3004 * Fixed LIST command reply sending in server. Affected file
3007 * Server now sends the kicker's client ID in the KICK notify
3008 to the kicked client. Affected file silcd/command.c.
3010 * The client library now parses the kickers client ID and
3011 UI displays it. Affected files lib/silcclient/client_notify.c
3012 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3014 * Made all payload parsing function prototypes consistent.
3015 They all take now const unsigned char * and uint32 pair as
3016 the payload data instead of SilcBuffer. Changes all around
3017 the source tree. Other unsigned char* -> const unsigned char*
3018 changes around the tree as well.
3020 * Optimized SFTP client and server packet sending not to
3021 allocate new buffer for each packet but to recycle the
3022 first allocated buffer. Affected files are
3023 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3025 * Optimized the SFTP client to use SilcList instead of
3026 SilcDList for requests, because it is faster. Affected file
3027 is lib/silcsftp/sftp_client.c.
3029 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3030 into lib/silccore/silcid.[ch].
3032 Renamed silcpayload.[ch] into silcargument.[ch].
3034 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * If client entry is deleted with active key agreement
3037 session, abort the session.
3039 The silc_client_abort_key_agreement now calls the completion
3040 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3042 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3045 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Don't use __restrict in older GCC's. Affected file is
3048 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3050 * silc_net_localhost now attempts to reverse lookup the
3051 IP/hostname. Affected file lib/silcutil/silcnet.c.
3053 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3054 command. It can be used to gain founder privileges at
3055 the same time when joining the channel.
3057 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3058 kicker's client ID as well. Updated protocol specs.
3060 Defined that the server must send SILC_COMMAND_IDENTIFY
3061 command reply with error status to client who sent
3062 private message with invalid client ID.
3064 Updated the protocol specification.
3066 * Added silc_server_send_command_reply to send any
3067 command reply. Affected file silcd/packet_send.[ch].
3069 * Added silc_id_payload_encode_data to encode ID payload
3070 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3072 * The server now send IDENTIFY command reply with error
3073 status if client ID in private message is invalid. Affected
3074 file silcd/packet_receive.c.
3076 * Save the server key file with server's IP address in
3077 the filename instead of hostname. The affected file is
3078 irssi/src/silc/core/client_ops.c.
3080 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3082 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3085 * Added libtool support for compiling shared objects in
3086 lib/silcsim. Affected file configure.in.pre and
3087 lib/silcsim/Makefile.am. Original patch by cras.
3089 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3091 * Pid file configuration, and server's config file fixes
3092 patch by toma. Updated CREDITS file.
3094 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3096 * Fixed silc_client_channel_message to not try to decrypt
3097 the message twice if it resolved the destination client
3098 information. This could cause of dropping one channel
3099 message. Affected file lib/silcclient/client_channel.c.
3101 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3104 lib/silcclient/client.c. This function is used when the SILC
3105 Client is run under some other scheduler, or event loop or
3106 main loop. On GUI applications, for example this may be
3107 desired to used to run the client under the GUI application's
3108 main loop. Typically the GUI application would register an
3109 idle task that calls this function multiple times in a second
3110 to quickly process the SILC specific data.
3112 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3114 * Fixed silc_server_drop() for dropping the supplementary
3115 groups as well, this could cause a security hole on some
3118 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3123 * Write PID file after dropping privileges. Added -F option
3124 to run server on foreground. A patch by debolaz.
3125 Affected files silcd/server.c, silcd/silcd.c.
3127 * Fixed MOTD to return the MOTD file server name. Affected
3128 file silcd/command.c.
3130 * Added INFO command reply handling to the Irssi SILC Client.
3131 Affected file irssi/src/silc/core/client_ops.c.
3133 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3135 * Fixed the silc_idcache_list_* routines to really support
3136 the dynamic list. Fixes a crash. Affected file is
3137 lib/silccore/silcidcache.c.
3139 * Fixed the LIST command reply to really call LIST command's
3140 pending callbacks. Affected file silcd/command_reply.c.
3142 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Update conn->local_entry->nickname after giving NICK
3145 command. Affected file lib/silcclient/command.c.
3147 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3149 * Added the [pid] option to the silcd configuration file
3151 Affected files: serverconfig.[ch] and silcd.c
3153 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Save fingerprint in WHOIS command reply in server.
3156 Affected file silcd/command_reply.c.
3158 * Fixed NICK commands pending callback registration.
3159 Affected file lib/silcclient/command.c.
3161 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3163 * Use ++server->cmd_ident when sending commands in server,
3164 instead of random number. Affected file silcd/command.c.
3166 * Fixed GETKEY command reply to call actually GETKEY pending
3167 command callbacks. Affected file silcd/command_reply.c.
3169 * A bit stricter check for nicknames. Check for same nickname
3170 in NICK command also. Affected file silcd/command.c.
3172 * Do not call INFO command everytime client ID changes, only
3173 during first connecting. Affected file lib/silcclient/client.c.
3175 * Set the new nickname only after successful command reply for
3176 NICK command is returned by server. Affected file
3177 lib/silcclient/command.c.
3179 * Remove nicknames from nicklist during server_signoff notify.
3180 Should fix /NAMES bit more. The affected file is
3181 irssi/src/silc/core/silc-channels.c.
3183 * Added `fingerprint' field to the SilcIDListData in the
3184 silcd/idlist.h to hold the fingerprint of the client's
3187 Send the fingerprint of the client's public key in WHOIS
3190 Affected files silcd/command.c, and silcd/idlist.[ch].
3192 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3193 create fingerprint from given data.
3195 * Show the fingerprint of the client's public key in WHOIS.
3196 Affected files irssi/src/module-formats.[ch] and
3197 irssi/src/silc/core/client_ops.c.
3199 * Format the multiple same nicknames also during JOIN and
3200 NICK_CHANGE notifys. Affected file is
3201 lib/silcclient/client_notify.c.
3203 * Do not print error on screen for invalid private message
3204 payload since it can come if someone is sending private
3205 messages with wrong key. Affected file
3206 lib/silccore/silcprivate.c.
3208 * Fixed multiple concurrent /PING crash. Affected file
3209 lib/silcclient/command.c.
3211 * Changed the wrong ID encoding. All IP addresses must be
3212 in MSB first order in encoded format. They were encoded
3213 wrong and was in LSB format. Affected files are
3214 silcd/serverid.c, lib/silcutil/silcutil.c.
3216 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3218 * Call the `connect' client operation through the scheduler
3219 in case of error. Affected file lib/silcclient/client.c.
3221 * Call the `failure' client operation even if the error
3222 occurred locally during a protocol. Affected file is
3223 lib/silcclient/protocol.c.
3225 * Added support of sending LIST command to router from normal
3226 server. This way normal server can get list of all channels
3227 in the network too. Fixed the channel list sending in the
3228 server too. Affected files are silcd/command.c, and
3229 silcd/command_reply.[ch].
3231 * Added silc_server_update_channels_by_server and
3232 silc_server_remove_channels_by_server. They are used during
3233 disconnection of primary router and in backup router protocol.
3234 Affected file silcd/server_util.[ch], silcd/server.c and
3235 silcd/server_backup.c.
3237 * Fixed channel adding to global list in IDENTIFY command
3238 reply in server. Affected file silcd/command_reply.c.
3240 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * If the incoming packet type is REKEY or REKEY_DONE process
3243 that packet always synchronously. Fixes yet another MAC
3244 failed error on slow (dialup) connections. Affected file
3245 lib/silcclient/client.c and silcd/server.c.
3247 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Call check_version SKE callback for initiator too. Affected
3250 file lib/silcske/silcske.c.
3252 * Implemented fix for security hole found in the SKE that was
3253 fixed in the specification few days back; the initiator's
3254 public key is now added to the HASH value computation.
3255 Added backwards support for the old way of doing it too, for
3256 old clients and old servers. Affected file is
3257 lib/silcske/silcske.c.
3259 * Enabled mutual authentication by default in SKE. If initiator
3260 is not providing mutual authentication the responder will
3261 force it. This will provide the proof of posession of the
3262 private key for responder. The affected files are
3263 lib/silcclient/protocol.c and silcd/protocol.c.
3265 * Do not cache anymore the server's public key during SKE.
3266 We do mutual authentication so the proof of posession of
3267 private key is done, and if the server is authenticated in
3268 conn auth protocol with public key we must have the public
3269 key already. Affected file silcd/protocol.c.
3271 * Added new global debug variable: silc_debug_hexdump. If
3272 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3273 file lib/silcutil/silclog.[ch].
3275 * Fixed compilation warning due to char * -> const char *.
3276 Affected files lib/silcutil/silcnet.h, and
3277 lib/silccore/silcauth.[ch].
3279 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3281 * Fixed CMODE command when new channel key was created. If
3282 the creation failed the old key was removed. Next time giving
3283 same command would crash the server since the old key was
3284 freed already. Affected file silcd/command.c.
3286 * Fixed the silc_server_announce_get_channels to not crash
3287 on reconnect. Affected file silcd/server.c.
3289 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Added silc_log_set_debug_string function to set a regex
3292 string to match for debug output. Only the function names,
3293 or filenames matching the given debug string is actually
3294 printed. This way it is possible to filter out those debug
3295 strings that user is not interested in.
3297 Fixed a bug in silc_string_regexify.
3299 Affected files lib/silcutil/silclog.[ch], and
3300 lib/silcutil/unix/silcunixutil.c.
3302 * Changed the -d options in both server and Irssi SILC client
3303 to take the debug string as argument. Affected files
3304 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3306 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Added silc_hash_babbleprint to create a Bubble Babble
3309 Encoded fingerprint. The encoding is developed by Antti
3310 Huima (draft-huima-babble-01.txt), and it creates human
3311 readable strings out of binary data. Affected file
3312 lib/silccrypt/silchash.[ch].
3314 * Print the babble print now in addition of fingerprint as well
3315 in Irssi SILC client. Affected files are
3316 irssi/src/fe-common/silc/module-formats.[ch],
3317 irssi/src/fe-common/silc/core/client_ops.c.
3319 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Fixed a security problem found in SKE. The initiator's
3322 public key too is now added to the HASH hash value creation
3323 which is signed by the responder to create the SIGN value.
3324 This will prevent anyone in the middle to lie to the responder
3325 about the initiator's public key. If this is done now, the
3326 man in the middle will get caught. Updated the protocol
3329 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * Better installation directory handling. Configure module
3332 paths and other paths automatically to example_silc* files
3333 in doc/. A patch by toma.
3335 * Fixed compiler warning from MPI library, and from SILC RNG.
3338 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3339 It can be configured with ./configure. A patch by toma.
3341 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Find correct make to use in prepare-clean. A patch by
3344 toma. Affected file prepare-clean.
3346 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3348 * Added irssi variables use_auto_addr, auto_bind_ip,
3349 auto_bind_port and auto_public_ip.
3351 * Changed the interface for silc_client_send_key_agreement
3352 in lib/silcclient/silcapi.h
3356 irssi/src/silc/core/silc-core.c
3358 lib/silcclient/silcapi.h
3359 irssi/src/silc/core/silc-channels.c
3360 lib/silcclient/client_keyagr.c
3363 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3365 * Added silc_pkcs_public_key_compare to compare two
3366 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3368 * Check that the client who set the founder mode on the
3369 channel is the same client that is giving the founder
3370 mode to itself. It is done by comparing the saved public
3371 key (it is saved even in the authentication is passphrase).
3372 Affected file silcd/command.c.
3374 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3376 * Do not process packet for disconnected socket connection.
3377 Affected file lib/silccore/silcpacket.c.
3379 * Process the DISCONNECT packet through scheduler in the
3380 client library. Affected file lib/silcclient/client.c.
3382 * Fixed the silc_client_packet_parse to not to increase
3383 the packet sequence number if the conn->sock and the
3384 current socket connection is not same. This can happen
3385 for example during key agreement when the conn includes
3386 multiple socket connections (listeners). Affected file
3387 lib/silcclient/client.c.
3389 * The sender of the file transfer request now provides also
3390 the pointer (listener) for the key exchange protocol. If
3391 the listener cannot be created then it sends empty key
3392 agreement and lets the receiver provide the listener.
3394 Added `local_ip' and `local_port' arguments to the
3395 silc_client_file_send. If they are provided they are used,
3396 if not then it will attempt to find local IP address, if
3397 not found or bind fails then the remote client will provide
3400 Affected files are lib/silcclient/client_ftp.c and
3401 lib/silcclient/silcapi.h.
3403 * Extended the FILE SEND command to support defining the
3404 local IP and port for key exchange listener. They are
3405 optional. Affected file irssi/src/silc/core/silc-servers.c.
3407 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Defined to WHOIS command reply the sending of fingerprint
3410 of the client's public key (if the proof of posession of the
3411 corresponding private key is verified by the server).
3412 Updated to the protocol specification.
3414 * Added support of receiving the client's public key's
3415 fingerprint in command reply in client library. Affected
3416 file is lib/silcclient/command_reply.c, and
3417 lib/silcclient/idlist.[ch].
3419 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Do not send over 128 chars long nickname to the server
3422 in NICK command. Affected file lib/silcclient/command.c.
3424 * Do not send over 256 chars long channel names to the server
3425 in JOIN command. Affected file lib/silcclient/command.c.
3427 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3429 * Assure that silc_server_close_connection cannot be called
3430 twice for same socket context. Affected file is
3433 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3435 * Send error message to application if opening file for
3436 writing during file transfer fails. Affected file is
3437 lib/silcclient/client_ftp.c.
3439 Remove all file transfer sessions for a client that we're
3440 removing from ID cache.
3442 Affected file is lib/silcclient/client_ftp.c.
3444 * Fixed silc_net_addr2bin to return correct address. Affected
3445 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3447 * Fixed file transfer session removing on signoff notify.
3448 Affected file irssi/src/silc/core/silc-servers.c.
3450 * Added the SilcClientFileError to be returned in the monitor
3451 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3452 Affected file lib/silcclient/silcapi.h.
3454 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Fixed a crash in silc_client_ftp_free_sessions and
3457 silc_client_ftp_session_free_client. Affected file
3458 lib/silcclient/client_ftp.c.
3460 * Added `disabled' field in the SilcChannelEntry in the server
3461 to indicate if the server entry is disabled. Affected file
3462 silcd/idlist.h, silcd/command[_reply].c.

3471 * Fixed a crash in client resolving in client_prvmsg.c in
3472 client library. Affected file lib/silcclient/client_prvmsg.c.
3474 * Do not actually remove the client directly from ID cache
3475 during SERVER_SIGNOFF, but invalidate it. This way we
3476 preserve the WHOWAS info for the client. Affected file
3477 silcd/server_util.c.
3479 * Fixed SERVER_SIGNOFF notify handling in the server. The
3480 server is now able to process incoming SERVER_SIGNOFF notify
3481 for a server that it doesn't even know about. It will remove
3482 the clients provided in the notify. Affected file
3483 silcd/packet_receive.c.
3485 * Check for partial packet in data queue after every packet that
3486 was found from the queue. Return and wait for more data if
3487 there is partial data in queue. Affected file is
3488 lib/silccore/silcpacket.c.
3490 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3495 Affected files lib/silcclient/silcapi.h and
3496 lib/silcclient/client_ftp.c.
3498 * Check that newsize in silc_buffer_realloc is larger than
3499 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3501 * Added better monitor of file transfers. It now monitors
3502 key agreement protocol during the file transfer too. Added
3503 error reporting too. Affected files

3505 irssi/src/fe-common/silc/module-formats.[ch].
3507 * Wrote a help file for FILE command.
3509 * Added silc_rng_global_get_byte_fast to get not-so-secure
3510 random data as fast as possible. Random data is read from
3511 /dev/urandom if available and from the SILC RNG if not
3512 available. It is used in padding generation. Affected file
3513 lib/silccrypt/silcrng.[ch].
3515 * All packets in client library are now processed synchronously.
3516 Optimized packet processing a lot. Affected file
3517 lib/silcclient/client.c.
3519 * All server connection packets are processing synchronously
3520 now in server, to optimize packet processing. Affected file
3523 * Include files are installed now only in Toolkit distribution
3524 if make install is given. Affected files: all Makefile.am's.
3526 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3528 * Assure that silc_client_notify_by_server_resolve does not
3529 resolve the client information multiple times. If it cannot
3530 be found by the first it cannot be found at all. Affected
3531 file lib/silcclient/client_notify.c.
3533 * Fixed WHOWAS command reply calling. Affected file
3534 lib/silcclient/command_reply.c.
3536 * Removed all references to silc_idlist_get_client from the
3537 Irssi SILC client since that call is internal call used by
3538 the library. The Irssi SILC client will use now client
3539 retrieval functions found in silcapi.h.
3541 * Fixed a bug in resolving nickname info before sending
3542 private message. It used freed memory. Affected file
3543 irssi/src/silc/core/silc-servers.c.
3545 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3547 * Assure my_channels statistics cannot go negative in server.
3548 Affected files silcd/server.c, silcd/server_util.c.
3550 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3564 * Added silc_net_localip to return local host's IP address.
3565 Affected file lib/silcutil/silcnet.[ch].
3567 * If key exchange or rekey protocol is active for a connection
3568 parse all packets syncronously since there might be packets
3569 in packet queue that we are not able to process without first
3570 processing packets before them. Affected file silcd/server,
3571 lib/silcclient/client.c.
3573 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3574 whether library should continue processing the packet.
3575 Affected file lib/silccore/silcpacket.h.
3577 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3606 lib/silcutil/silcutil.[ch].
3608 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Resolve the client info when received private message or
3611 channel message for a client which nickname we don't know.
3612 Affected files lib/silcclient/client_prvmsg.c and

3625 Make sure also that USERS command reply does not resolve
3626 twice information. Affected file is
3627 lib/silcclient/command_reply.c.
3629 Make sure that silc_client_get_clients_by_list does not
3630 resolve twice same information.
3632 * Check for valid client->id in the silc_server_free_client_data.
3633 Affected file silcd/server.c.
3635 * Fixed /GETKEY nick@server not to crash if the server entry
3636 is not found. Affected file lib/silcclient/command.c.

3644 Affected file silcd/command.c.
3646 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3648 * Call the silc_server_udpate_servers_by_server in the
3649 primary router that comes back online in the backup resuming
3650 protocol. Otherwise it routes packets wrong. Affected file
3651 silcd/server_util.[ch], silcd/server_backup.c.
3653 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3655 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3656 lib/silcutil/silcbuffmt.[ch].
3658 * Redefined the SILC packet header to include the padding
3659 length. Affected file lib/silccore/silcpacket.[ch].
3661 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3662 length for maximum padding up to 128 bytes). Affected
3663 file lib/silccore/silcpacket.h.
3665 * Removed all backwards support for old 0.5.x MAC thingies.
3666 The SILC packet header change makes it impossible to be
3667 backwards compatible.
3669 * Send the ENDING packet with timeout in the backup resuming
3670 protocol. This is to assure that all routers has connected
3671 to the primary router. Affected file silcd/server_backup.c.
3673 * Changed the RNG to take the first IV from random data. It
3674 used to take it from zero actually. Changed the RNG also
3675 to use /dev/urandom during session. /dev/random is used
3676 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3678 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Changed the SILC packet header to have the first two bytes
3681 (the packet length) encrypted. Affected files aroung the
3682 code tree, lib/silccore/silcpacket.[ch]. Removed the
3683 SilcPacketCheckDecrypt callback. It is not needed anymore
3684 since the silc_packet_receive_process will determine now
3685 whether the packet is normal or special.
3687 * Implemented the unidirectional MAC keys. Affected files
3688 lib/silcske/silcske.c, silcd/protocol.c and
3689 lib/silcclient/protocol.c.
3691 * Implemented the packet sequence number to the MAC computation.
3692 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3693 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3694 lib/silcclient/protocol.c.
3696 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3698 * Allow backup router to announce servers. All servers
3699 announced by backup router are added to the global list
3700 automatically. Update hte server's socket to our primary
3701 router also when backup router announces a server.
3702 Affected file silcd/packet_receive.c.
3704 * Do not update the client->router in the function
3705 silc_server_udpate_clients_by_server if the client is on
3706 global list. We might fail to find any specific server
3707 for locally connected clients and local cell clients. They
3708 should still use the `from' and not `to' as client->router.
3709 This fixes backup router resuming protocol. Affected file
3710 silcd/server_util.c.
3712 * Decrease channel statistics count only if the channel
3713 deletion worked. Affected files are silcd/server.c and
3714 silcd/server_util.c.
3716 * Added silc_server_update_servers_by_server to update origin
3717 of all server entries. Used during backup router protocol.
3718 Affected files silcd/server_util.[ch], silcd/server.c. and
3719 silcd/backup_router.c.
3721 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3722 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3723 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3724 lib/silccrypt/silchmac.c.
3726 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3728 * Assure that router cannot reroute the same channel message
3729 to the sender. Affected file silcd/packet_receive.c.
3731 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Made better checks that the channel message is not sent
3734 to the router it came from. Affected file is
3735 silcd/packet_send.c. Fixed memory leak too.
3737 * Announce informations for incoming router connection, but
3738 only after checking if it is replaced by backup router.
3739 Affected file silcd/packet_receive.c.
3741 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Fixed the backup resuming protocol to work in multiple
3744 router environment. Affected file silcd/server_backup.c.
3746 * Route packet only to one router in the function
3747 silc_server_packet_send_to_channel. Affected file is
3748 silcd/packet_send.c.
3750 * Fixed silc_server_send_notify_dest to set the broadcast
3751 flag. Fixed the silc_server_send_notify_topic to actually
3752 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3753 Affected file silcd/packet_send.c.
3755 * Changed the SFTP Filesystem interface. Changed the
3756 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3757 the filesystem operation function. The SilcSFTPFilesystem
3758 is now a context that is allocated by all filesystem allocation
3759 functions and it already includes the operations structure
3760 and filesystem specific context. It is given as argument
3761 now to the silc_sftp_server_start. This made the interface
3762 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3763 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3765 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * Changed the backup router adding and getting interfaces
3768 in the server. The router that will be replaced by the
3769 specified backup router is now sent as argument. Affected
3770 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3773 * Added silc_net_addr2bin_ne to return the binary form of
3774 the IP address in network byte order. Affected files
3775 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3777 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3779 * Check for existing server ID in silc_server_new_server
3780 and in silc_server_connect_to_router_final and remove the
3781 old entry if it exists. Affected file silcd/packet_receive.c,
3784 * Send the channel message always to only one router, either
3785 in upstream or downstream. Affected file is
3786 silcd/packet_send.c.
3788 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3790 * Wrote the definition of the backup resuming protocol to the
3791 protocol specification.
3793 * Removed one redundant channel key generation from normal
3794 server during joining procedure. Removed one redundant
3795 channel key sending from server to router during joining
3796 procedure. Affected file silcd/command.c.
3798 * Made minor bugfixes to the backup router resuming protocol.
3799 Affected file silcd/server_backup.c, server.c.
3801 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3803 * Added --disable-asm configuration option. Affected files
3804 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3807 * Implemented the backup resuming protocol that is used to
3808 resume the primary router position in the cell after the
3809 primary router comes back online. Affected files
3810 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3811 and silcd/server_util.[ch].
3813 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Sleep two (2) seconds after sending QUIT command to server.
3816 Affected file lib/silcclient/command.c.
3818 * Assure that if outgoing data buffer is pending do not force
3819 send any data. Affected file silcd/packet_send.c.
3821 * Assure that if outgoing data buffer is pending do not force
3822 send any data. Affected file lib/silcclient/client.c.
3824 * Implemented the backup router support when the primary router
3825 goes down. The servers and routers can now use the backup
3826 router as new primary router without loosing connectivity.
3828 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3831 in the server to indicate disabled entry. All data read
3832 from the connection will be ignored and no data is sent
3833 for entry that is disabled. Affected files are
3834 silcd/idlist.h, silcd/server.c.
3836 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3838 * Created SFTP client and server test programs in the
3839 lib/silcsftp/tests directory.
3841 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3843 * Implemented memory filesystem (virtual filesystem) for
3844 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3847 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3849 * Implemented the SFTP (SSH File Transfer Protocol) to the
3850 lib/silcsftp. It includes SFTP client and SFTP server
3853 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3855 * Moved lib/silccore/silcprotocol.[ch] to the
3856 lib/silcutil library.
3858 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3859 take variable argument list pointer as argument. Affected
3860 file lib/silcutil/silcbuffmt.[ch].
3862 * Added silc_buffer_set function that is used to set data
3863 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3864 Affected file lib/silcutil/silcbuffer.h.
3866 * Changed various routines in the core library to use the new
3867 silc_buffer_set instead of allocating new buffer only for
3870 * Added 64-bit value formatting and unformatting support to the
3871 silc_buffer_[un]format routines. Affected file is
3872 lib/silcutil/silcbuffmt.[ch].
3874 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3875 to includes/bitmove.h.
3877 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3879 * Fixed channel user mode saving in client library. Affected
3880 file lib/silcclient/command[_reply].c.
3882 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3884 * Defined the file transfer to the SILC Protocol. Added
3885 new packet type SILC_PACKET_FTP and defined File Transfer
3886 Payload. The mandatory file transfer protocol is SFTP
3887 (SSH File Transfer Protocol). Affected file in addition
3888 of the internet draft is lib/silccore/silcpacket.h.
3890 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3891 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3892 is used as part of backup router protocol when the primary
3893 router of the cell is back online and wishes to resume
3894 the position as primary router.
3896 * Redefined the MAC generation keys in the protocol. The
3897 same key is not used anymore in both direction. Both
3898 direction will now use different keys for sending and
3899 receiving. This fixes a potential security flaw. This
3900 change causes incompatibilities in the protocol.
3902 * Redefined also the MAC computation from the packet.
3903 An packet sequence number is now added to the MAC
3904 computation. This prevents possible replay attacks against
3905 the protocol. This change too causes incompatibilities
3908 Added `sequence' field to the SilcPacketContext to hold
3909 the current sequence number for the packet.
3911 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Added `created' field to the SilcIDListData in the file
3914 silcd/idlist.h to indicate the time when the entry was
3917 * Added `created' field to the SilcChannelEntry too. Affected
3918 file silcd/idlist.h.
3920 * Added `creation_time' aguments to all the announcement functions
3921 in the server. If it is provided then only the entries that
3922 was created after the provided time frame are actually
3923 announced. Affected file silcd/server.[ch].
3925 * The protocol says that the Channel ID's IP address must be
3926 based on the router's IP address. Added check for this in
3927 the silc_server_new_channel when processing incoming New Channel
3928 Payload. Affected file silcd/packet_receive.c.
3930 * Print out the correct version with --version in SILC client.
3931 Affected file irssi/src/silc/core/silc-core.c.
3933 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3935 * Fixed WHOWAS command to check for completnes of the client
3936 entry always, not just when the command is coming from client.
3937 Affected file silcd/command.c.
3939 * Added new function silc_server_packet_queue_purge to purge the
3940 outgoing data queue to the network. After the function returns
3941 it is guaranteed that the outgoing packet queue is empty.
3942 Affected file silcd/packet_send.[ch].
3944 * Purge the outgoing packet queue in the rekey protocol's final
3945 callback to assure that all rekey packets go to the network
3946 before quitting the protocol. Affected file silcd/server.c.
3948 * Added silc_client_packet_queue_parse as similar function as
3949 in server to the client library. The affected file is
3950 lib/silcclient/client.c.
3952 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3954 * Splitted silcd/server.c and created silcd/server_util.[ch]
3955 for utility functions.
3957 * Added new socket flag SILC_SF_DISABLED to indicate that the
3958 connection is open but nothing can be sent to or received from
3959 the connection. Affected file lib/silcutil/silsockconn.[ch].
3960 The checking for disabled socket is checked in the low level
3961 silc_socket_write and silc_socket_read functions.
3963 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3965 * Allow only nicknames and channel names that fits into the
3966 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3968 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3970 * When processing JOIN command reply in server check that if
3971 the channel exists in our global list we'll move it the local
3972 list. Affected file silcd/command_reply.c.
3974 * Fixed the check whether client is joined on the channel already
3975 in JOIN command. Affected file lib/silcclient/command.c.
3977 * Fixed the JOIN command reply to check whether the channel
3978 already exists. Affected file lib/silcclient/command_reply.c.
3980 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3982 * Added silc_ske_status_string to map the SKE error numbers
3983 to readable strings. The affected files are
3984 lib/silcske/silcske[_status].[ch].
3986 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3988 * Do not show the private channels on the WHOIS channel list
3989 as it is not allowed by the protocol. The affected file is
3992 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3994 * Assure that the packet length digged from the actual packet
3995 is something sensible in the silc_packet_decrypt_rest_special
3996 in lib/silccrypt/silcpacket.c.
3998 * Free and NULL the allocated pointer in silc_hmac_alloc if
3999 the HMAC allocation fails. The affected file is
4000 lib/silccrypt/silchmac.c.
4002 * Print the selected security properties to the log files in
4003 the server. Affected file silcd/protocol.c.
4005 * Add SKE's reference counter even if calling the completion
4006 callback manually. Otherwise it goes negative, although it
4007 does not cause any problems. The affected file is
4008 lib/silcske/silcske.c.
4010 * Remove the client entry with short timeout after giving the
4011 KILL command. Affected file lib/silcclient/command.c.
4013 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4014 case all found clients are already disconnected (WHOWAS would
4015 found them) in the server. Affected file silcd/command.c.
4017 * Update the last_receive (time of last data received) to be
4018 updated only when received private or channel message so that
4019 the idle time showed in WHOIS makes more sense.
4021 * Added boolean field `valid' in to the SilcClientEntry in the
4022 client library to indicate whether the entry is valid or not.
4023 This fixes the nickname change bug on channel when changing
4024 the nickname to be same than the old (like nick to Nick) the
4025 nickname formatter doesn't set the new nick anymore to Nick@host.
4026 Affected file lib/silcclient/idlist.[ch].
4028 * Now actually fixed the nickname changing on disconnection.
4029 Added new function silc_change_nick to the Irssi SILC Client.
4030 Affected file irssi/src/silc/core/client_ops.c,
4031 irssi/src/silc/core/silc-nicklist.[ch].
4033 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Check that the public key exists in the GETKEY command before
4036 trying to encode it. Affected file silcd/command.c.
4038 * Print some notifications on received public keys with GETKEY
4039 command in the Irssi SILC Client. Affected files are
4040 irssi/src/fe-common/silc/module-formats.[ch],
4041 irssi/src/silc/core/client_ops.c.
4043 * Use IDENTIFY command to resolve the server information in the
4044 GETKEY command instead of INFO command. Affected file
4045 lib/silcclient/command.c.
4047 * All command reply functions in the client library now calls
4048 the pending command reply callbacks even if an error has
4049 occurred. The server has done this a long time and now it was
4050 time to move the client library to this as well. Now all
4051 errors can be delivered back to the pending command reply
4052 callbacks if necessary. Affected files are
4053 lib/silcclient/command[_reply].[ch].
4055 * Change the nickname on disconnection back to the username
4056 because in reconnect the server will enforce it to it anyway.
4057 Affected file irssi/src/silc/core/silc-servers.c.
4059 * Fixed a config file parsing bug in the Irssi SILC client.
4060 Affected file irssi/src/silc/core/clientconfig.c.
4062 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4064 * When printing the channel mode on JOIN, verify that the
4065 channel key and channel's HMAC are valid. Affected file
4066 irssi/src/silc/core/client_ops.c.
4068 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4071 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4072 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4074 * Removed channel key rekey task deleting from the function
4075 silc_server_save_channel_key. Affected file silcd/server.c.
4076 Added explicit timeout task context instead that is used to
4077 delete the task if we are registering a new task before the
4078 new task has elapsed.
4080 * When channel key rekey occurs the client library now saves
4081 the old channel key for a short period of time (10 seconds) and
4082 is able to use it in case some is still sending channel
4083 messages encrypted with the old key after the rekey. Affected
4084 file lib/silcclient/[idlist.h|client_channel.c].
4086 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4088 * Added check to the silc_server_new_id_real to not accept
4089 new ID if it is the sender's own ID. Affected file is
4090 silcd/packet_receive.c.
4092 * Assure that we do not announce ourself or the one we've
4093 sending our announcements when we're router and are announcing
4094 servers to our primary router. Affected file silcd/server.c.
4096 * Fixed silc_server_command_identify_check_client to assemble
4097 correct WHOIS packet. It send corrupted WHOIS packet and
4098 caused problem with router to router connections. Affected
4099 file silcd/command.c.
4101 Fixed also silc_server_command_whois_check the same way
4102 as for the IDENTIFY command.
4104 * Added new SilcIDListStatus to the server in the SilcIDListData
4105 structure. The status now includes the current status of
4106 the entry (like registered, resolved etc.). Affected file
4107 silcd/idlist.[ch]. Defined a bunch of different status types
4108 as well. This replaced the old boolean registered field as well.
4110 Added resolve_cmd_ident field to the SilcClientEntry structure
4111 too so that if the entry is for example being resolved so
4112 another command may attach to the same pending command reply
4113 without requiring to resolve the same entry again. This concept
4114 should optimize the WHOIS and the IDENTIFY resolving under
4115 heavy load by taking away unnecessary resolving for entries
4116 that are being resolved already.
4118 Added support for adding multiple pending commands for one
4119 command idenfier. Affected file silcd/command[_reply].[ch].
4121 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4122 before deleting the data. Otherwise the hash table will have
4123 freed data in comparison functions. Affected file is
4124 silcd/command_reply.c.
4126 * Fixed silc_idlist_replace_client_id to add the new entry to
4127 the cache with NULL nickname. Otherwise there will be invalid
4128 memory as the nickname after the nickname is freed. Affected
4129 file silcd/packet_receive.c.
4131 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4132 saved into wrong slots because the previous number of entries
4133 was not taken into account. Affected file silcd/idlist.c.
4134 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4136 * If we are router and we receive JOIN notify to a channel that
4137 does not have any users then notified client is marked as the
4138 channel founder, as it is it. The affected file is
4139 silcd/packet_receive.c
4141 * Added to the extended hash table API's table_del_*ext functions
4142 the destructor as argument too, so that the caller can decide
4143 which destructor to use or whether to use destructor at all.
4144 Affected file lib/silcutil/silchashtable.[ch].
4146 * Fixed ID Cache purging. It actually deleted the entries from
4147 the hash table after the data was freed. The hash table ended
4148 up comparing freed memory. The affected file is
4149 lib/silccore/silcidcache.c.
4151 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4153 * Fixed Irssi SILC client's KILL command's HELP syntax.
4155 * The USERS command now resolves the detailed user information
4156 if the userinfo field is missing. Affected file is
4157 lib/silcclient/command_reply.c.
4159 * Do not print error in silc_file_read if the read file does
4160 not exist. Just silently return NULL. Affected file is
4161 lib/silcutil/silcutil.c.
4163 * Fixed the silc_log_output to not wine about NULL filename
4164 and to not create some bogus " " filename. Affected file is
4165 lib/silcutil/silclog.c.
4167 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4169 * Fixed various printing bugs on the user interface in the
4170 Irssi SILC Client. Minor changes that were forgotten from
4173 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4175 * Fixed the configure.in.pre and the compilation and distribution
4176 environment to support the new autoconf 2.52. That version is
4177 now required to compile the CVS trunk.
4179 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4181 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4182 to generally parse user@fqdn format strings. Affected file
4183 lib/silcutil/silcutil.c.
4185 * Added nickname_format and nickname_force_format fields to the
4186 SilcClientParams structure. The first one defines the format
4187 for the nicknames that the library will enforce if the receives
4188 multiple same nicknames. The second one is boolean value and
4189 can be used to force the library to always enforce the format
4190 to the nicknames regardles whether there are multiple nicknames
4191 or not. This configurable formatting was employed to flexibly
4192 support accessing multiple nicknames from the user interface.
4193 The userinterface can now set the nicknames to what ever format
4194 they prefer. Affected file lib/silcclient/silcapi.h.
4196 Added function silc_client_nickname_format to the file
4197 lib/silcclient/idlist.c. It performs the nickname formatting.
4199 Added new field `hostname´ to the SilcClientEntry context.
4200 It holds the hostname of the client. Affected file is
4201 lib/silcclient/idlist.h.
4203 * Irssi SILC Client sets the nicknames in nick@hostn format.
4204 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4205 irssi/src/silc/core/silc-core.c.
4207 The WHOIS printing now also shows both the real nickname and
4208 the formatted nickname so that user knows how to access the
4209 user if there are multiple same nicknames cached. Affected
4210 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4211 printing formatting too to take the hostname now as a separate
4212 argument. The Affected file is
4213 irssi/src/fe-common/silc/modules-formats.[ch].
4215 * Changed the silc_client_get_clients_local to accept the formatted
4216 nickname as argument. It accepts the real nickname too but the
4217 formatted nickname can be used to find the true entry from
4218 multiple entries. Affected file lib/silcclient/silcapi.h and
4219 lib/silcclient/idlist.c.
4221 * Added nickname_format_parse field to the SilcClientParams.
4222 It is a callback function provided by the application to parse
4223 the nickname out of the formatted nickname string. The library
4224 calls it to get the nickname from the formatted string. Since
4225 the application generally knows better the format of the nickname
4226 string it parses it instead of the library, even though library
4227 encodes the formatted string. If the callback function is not
4228 provided then the library will use the string as is. The
4229 affected file is lib/silcclient/silcapi.h.
4231 * All the nickname strings passed to the client library in
4232 commands are now expected to be formatted nickname strings.
4233 If the command does not support the formatted nickname string
4234 it will assume that the sent string is the actual nickname.
4235 Affected file lib/silcclient/command.c.
4237 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4239 * Added public key authentication support to OPER and SILCOPER
4240 commands in the client library. Affected file is
4241 lib/silcclient/command.c.
4243 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4245 * Changed the get_auth_methdod client operation to be asynchronous.
4246 It can be async if the application resolves the authentication
4247 method from the server during the negotiation. Added new
4248 SilcGetAuthMeth completion callback that the application will
4249 call after resolving the authentication method.
4251 Added function silc_client_request_authentication_method that
4252 the application can use to resolve the authentication method
4253 from the server. Added also SilcConnectionAuthRequest callback
4254 that the library will call after the server has replied. The
4255 application can call this function if it does not know the
4256 current authentication method.
4258 Affected files are lib/silcclient/client.c and
4259 lib/silcclient/silcapi.h.
4261 * The Irssi SILC client now automatically resolves the authentication
4262 method incase any configuration information is not present (and
4263 currently there never is). The affected file is
4264 irssi/src/silc/core/client_ops.c.
4266 * Fixed public key authentication from the client library.
4267 Affected file lib/silcclient/protocol.c. Changed also the
4268 protocol specification about the public key authentication in
4269 the connection authentication protocol. The actual data to be
4270 signed is now computed with a hash function before signing.
4272 * Fixed the public key authentication from the server as well.
4273 Affected file silcd/protocol.c.
4275 * Removed the mlock()'s from the memory allocation routines.
4276 Affected file lib/silcutil/silcmemory.c. The ./configure does
4277 not check anymore for the mlock(). Affected file is
4280 * Fixed USERS command in server to allow the execution of the
4281 command for private and secret channels if the client sending
4282 the command is on the channel. Affected file silcd/command.c.
4284 * Fixed silc_client_get_clients_local to return the clients
4285 count correctly. It could return wrong value. Affected file
4286 lib/silcclient/idlist.c.
4288 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4290 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4291 types. The assembler optimizations seemed not to like 64-bit
4292 data types. The assmebler optimizations thus are now enabled
4293 also for BSD systems as opposed to only enable them for Linux.
4295 * Do not check for threads at all on BSD systems. Affected
4296 file configure.in.pre.
4298 * Removed -n and -h options from the Irssi SILC Client since
4299 they are not used in silc.
4301 * Fixed the prime generation to assure that the first digit
4302 of the generated random number is not zero since our conversion
4303 routines does not like number strings that starts with zero
4304 digit. If zero digit is seen the random number is regenerated.
4305 This caused some corrupted RSA keys when the zero first digit
4306 was met. Affected file lib/silcmath/silcprimegen.c.
4308 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4310 * Fixed WIN32 configuration in the ./configure script.
4311 Fixed to include xti.h on environments that has it.
4312 Patches by Carsten Ilchmann and andrew.
4314 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4316 * Changed the silc_id_create_client_id to be collision
4317 resistant. It is now assured that there cannot be created
4318 two same client ID's. I suspect that some weird bugs in
4319 the server were actually caused by duplicate Client IDs.
4320 Affected file silcd/serverid.[ch]. A router receiving
4321 new ID now also assures and informs the sending server
4322 if the ID caused collision.
4324 * Changed the silc_id_create_channel_id to also assure that
4325 there are no collisions.
4327 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4329 * Statement about ignoring the Mutual Authentication flag when
4330 performing rekey with PFS was a bit misleading. It is ignored
4331 if it was set in the initial negotiation, it cannot be even
4332 set in the rekey. Fixed in the ke-auth draft. Started the
4333 new versions of the protocol drafts in the doc/.
4335 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4337 * Fixed a bug in silc_client_command_identify_save when saving
4338 new channel information. The channel name was no duplicated
4339 and caused crash on exit. Affected file is
4340 lib/silcclient/command_reply.c.
4342 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4344 * Fixed the getkey command handling in the server. Send just
4345 empty OK reply to the sender if the key could not be fetched
4346 (but everything else was ok, like the key just was not available).
4347 Changed the public key parameter to optional in the protocol
4348 specs so that empty OK reply can be sent. Affected file
4351 Added a message to Irssi SILC client to tell to user if the
4352 server did not return a public key.
4354 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Fixed a channel key regeneration bug. It registered new
4357 timeout tasks exponentially until all system resources were
4358 used. Affected file silcd/server.c.
4360 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4362 * Added the SILC Document generator to the scripts/silcdoc.
4363 It can be used to generate the Toolkit Reference Manual out
4364 of the source tree. Internally it will also use the RoboDoc
4365 generator now imported in util/robodoc.
4367 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4369 * Added couple of return's in rekey protocol if error orccurred
4370 during the protocol. The execution must be terminated.
4371 Affected file silcd/protocol.c. Also, terminate the protocol
4372 always with timeout.
4374 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * The client's Client ID was created initally from the wrong
4377 nickname (it could have been in format nick@host) in the
4378 silc_server_new_client. Affected file silcd/packet_receive.c
4380 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4382 * Added some SILC_LOG_ERROR's to various error conditions
4383 if client could not be added to ID cache. Affected files
4384 silcd/packet_receive.c and silcd/server.c.
4386 * When client's sock->user_data is freed, NULL also the
4387 client->router and client->connection pointers. Added check
4388 for these pointers being NULL to various places around the
4389 code. Affected file silcd/server.c.
4391 * Added client->data.registered == TRUE checks to various
4392 places around the code to assure that unregistered client's
4393 are not handled when it is not allowed. Affected file
4396 * Added `bool registered' fields to all
4397 silc_idlist_[server|client]_get_* routines to indicate whether
4398 the fetched client needs to be registered or not. Affected
4399 file silcd/idlist.[ch].
4401 * Add your own entry as registered to the ID cache in the
4402 server. Affected file server.c.
4404 * Fixed a bug in silc_server_new_server. The SilcServer was
4405 set as the new server's context instead of SilcServerEntry.
4406 This naturally caused some weird bugs.
4408 * Added "updated" field the SilcChannelEntry which indicates
4409 the time since the channel entry was last accessed. This
4410 can be used to determine whether it is necessary to
4411 announce the channel after backup resuming protocol.
4412 Affected files silcd/idlist.[ch].
4414 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4416 * Do not delete the channel rekey task when adding it
4417 for in silc_server_create_channel_key.
4419 * Changed the silc_server_create_channel_key to return
4420 TRUE or FALSE to indicate the success of the channel key
4423 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4425 * Fixed MSVC++ project files and added missing files to
4426 Makefiles under win32/.
4428 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4430 * Do not add TCP_NODELAY flag if the operating system
4431 does not have it defined. Affected files are
4432 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4434 * Fixed buffer overflow from Irssi SILC Client. Affected
4435 file irssi/src/fe-common/core/themes.c.
4437 * Fixed double free in client library in the file
4438 lib/silcclient/client.c when disconnecting from server.
4440 * Applied double free patch from cras to Irssi SILC client.
4441 Affected files irssi/src/core/[modules/expandos].c
4443 * Fixed the disconnection handling to Irssi SILC Client.
4444 The application must call silc_client_close_connection
4445 in ops->connect client operation in case of failure of
4446 the connection. Affected file is
4447 irssi/src/silc/core/client_ops.c.
4449 * Do not set sock->protocol to NULL in the function
4450 silc_client_close_connection after executing the protocol's
4451 final callback since the sock might not be valid anymore.
4452 Affected file lib/silcclient/client.c.
4454 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4456 * Do not enable SILC_THREADS if the linking with libpthread
4457 did not happen. Affected file configure.in.pre.
4459 * Added notion to protocol specification that server must
4460 verify the sent authentication payload with CMODE when
4461 setting the channel founder key. Implemented it to the
4462 server. Affected file silcd/command.c.
4464 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4466 * Added _EXTRA_DIST SILC distribution variable to the
4467 distributions file. It is used to conditionally add extra
4468 files or directories to the specific distribution. Affected
4469 files ./prepare, Makefile.am.pre and distributions.
4471 Removed the `_' from the start of the distribution names.
4474 * Added README.WIN32 for instructions to compile the Toolkit
4477 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4479 * Fixed a double free in disconnection in the server. Affected
4480 file is silcd/server.c.
4482 * Fixed the lib/silcske/groups.c to work now also with GMP
4483 MP library. The string conversion did not work when using
4484 specific base and the base is indicated in the string as well.
4486 * Created win32/ directory which now includes MSVC++ specific
4487 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4488 It will appear only in the toolkit distribution
4490 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4492 * Changed the key material distribution function in case when
4493 the hash output is too short. The data is now concatenated
4494 a bit differently than it used to. Made the change to the
4495 SKE protocol specification.
4497 * Added better GMP detection to configure.in.pre. A patch
4500 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4502 * Fixed a minor bug in SKE that might cause some problem on
4503 some platforms. Affected file lib/silcske/silcske.c.
4505 * Added the cookie checking for initiator in the SKE. It checks
4506 that the responder returns the sent cookie unmodified. The
4507 affected file is lib/silcske/silcske.c. Added new SKE
4508 error type INVALID_COOKIE that can be sent during the
4509 negotiation. Fixed some memory leaks as well.
4511 * Added the "invalid cookie" error message to Irssi SILC client's
4514 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4516 * Added `task_max' field to the SilcClientParams to indicate
4517 the maximum tasks the scheduler can handle. If set to zero,
4518 default values are used. Affected file lib/silcclient/silcapi.h.
4520 * Fixed memory leaks in silc_client_close_connection. Affected
4521 file lib/silcclient/client.c.
4523 * Added silc_client_del_client_entry to client library to free
4524 all memory of given client entry. Affected file is
4525 lib/silcclient/idlist.[ch].
4527 * Added new functions silc_client_del_channel and
4528 silc_client_del_server to delete channel and server entries.
4529 Affected file lib/silcclient/[silcapi.h/idlist.c].
4531 * Removed silc_client_del_client_by_id from silcapi.h.
4533 * Fixed the INFO command to return the server's own info
4534 correctly when querying by Server ID. Affected file is
4537 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Removed the non-blocking settings in WIN32 code in the
4540 silc_sock_[read/write] and added SleepEx instead. Affected
4541 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4542 of input data is now checked with FIONREAD and ioctlsocket.
4544 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4546 * Call silc_schedule_task_del_by_context in the
4547 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4548 Affected file lib/silccore/silcprotocol.c.
4550 * Call silc_protocol_cancel for active protocols in the
4551 silc_server_close_connection if the funtion
4552 silc_server_free_sock_user_data has not been called.
4553 Affected file silcd/server.c.
4555 * Generic tasks cannot be deleted using the del_by_fd
4556 task deleting function since generic tasks does not match
4557 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4559 * Added a notion to SILCOPER help file that the SILCOPER works
4560 only on router server, not on normal server.
4562 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4564 * Added for WIN32 support for the new scheduler as well.
4565 Affected file lib/silcutil/win32/silcwin32schedule.c.
4567 * Fixed the SHA1 implementation to work on various platforms.
4569 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4571 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4572 API. It is part of the scheduler now. Everything else is
4573 as previously but some functions has changed their names.
4574 Checkout the lib/silcutil/silcschedule.h for the interface.
4575 Updated all applications to use the new interface. Affected
4576 files are lib/silcutil/silcschedule.[ch].
4578 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4580 * Found a bug in the SKE implementation. The HASH value,
4581 specified by the protocol, was not computed correctly. The
4582 public key of the responder was not added to the computation
4583 even though it is mandatory. Affected file lib/silcske/silcske.c.
4584 This unfortunately causes incompatibilities with older
4585 clients and servers.
4587 * Added WIN32 specific network init and uninit functions:
4588 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4589 the Winsock2. Affected file lib/silcutil/silcnet.h and
4590 lib/silcutil/win32/silcwin32net.c.
4592 * Set the socket always to nonblocking mode on WIN32 after
4593 reading data or writing data. Affected file is
4594 lib/silcutil/win32/silcwin32sockconn.c.
4596 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4598 * Fixed various compilation problems under WIN32. Affected
4599 files lib/silcutil/win32/silcwin32thread.c and
4600 lib/silcutil/win32/silcwin32schedule.c.
4602 * Removed all _internal.h #includes from public header
4603 files. Internal headers must never be included from
4606 Removed also the lib/silcske/payload_internal.h file.
4608 * All include files that may be needed (public and some others
4609 included by the public headers) by application developers are
4610 now copied to the ./includes directory. It does not copy any
4611 internal headers. Affected file Makefile.defines.pre and all
4612 Makefile.am's under lib/ and subdirs.
4614 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4616 * Do not change the ~/.silc directory's permissions automatically.
4617 Affected file irssi/src/silc/core/clientutil.c.
4619 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4621 * Do not cancel the protocol in silc_server_close_connection
4622 it might cause recursion. Now cancelled in the function
4623 silc_server_free_sock_user_data. Affected file silcd/server.c.
4625 * Fixed the silc_server_remove_clients_by_server to regenerate
4626 the channel keys correctly finally. Added also new function
4627 silc_server_remove_clients_channels to actually do it.
4628 Affected file silcd/server.c.
4630 * Fixed the silc_server_new_channel to not crash by giving
4631 wrong router to the new channel. Affected file is
4632 silcd/packet_receive.c.
4634 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4636 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4637 which is given as argument to the silc_client_alloc now.
4638 It can be used to configure the client and set various parameters
4639 that affect the function of the client.
4641 * The USERS command in server did not check whether the channel
4642 is private or secret. Affected file silcd/command.c.
4644 * Added new argument to the USERS command in protocol specification.
4645 The USERS command now can take the channel name as argument
4646 as well. Added support for this in client and server and
4647 updated the protocol specs.
4649 * Completed the GETKEY command in client. It can be now used
4650 to fetch also servers public key not only some clients.
4651 Affected files lib/silcclient/command[_reply].c.
4653 * Added silc_client_get_server to return server entry by the
4654 server name. Affected files lib/silcclient/silcapi.h and
4657 * Redefined the IDENTIFY command in protocol specification to be
4658 more generic. It now can be used to query information about
4659 any entity in the SILC Network, including clients, servers and
4660 channels. The query may be based either the entity's name
4661 or the ID. Added support for this in both client and server.
4663 Affected files silcd/command.c and lib/silcclient/command.c
4664 and command_reply.c.
4666 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4667 the _from_client and _from_server functions. Affected file
4670 * Added silc_client_get_channel_by_id_resolve to the file
4671 lib/silcclient/silcapi.h to resolve channel information by
4672 its ID. Added also silc_client_get_channel_by_id that
4673 does not resolve it from the server.
4675 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4677 * Added SilcServerEntry context into the client library
4678 to represent one server. The INFO command now allocates
4679 these to save the resolved server info. For now on the
4680 client library will also keep information about servers,
4681 connected and resolved with INFO.
4683 The INFO command now allocates the SilcServerEntry context
4684 and saves the server info there. The COMMAND_REPLY in
4685 the INFO now returns the parameters to application in
4686 same order as defined in the protocol specification.
4688 The entries are cached in the client->server_cache.
4690 * The INFO command is now issued after received the Client ID
4691 from the server. Affected file lib/silcclient/client.c.
4693 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4694 to the application as the mode changer might be server.
4695 It is guaranteed that NULL is not returned anymore to the
4696 application. Affected file lib/silcclient/client_notify.c.
4698 The ID Type is now also passed to the application so that
4699 it can check whether the returned entry is SilcClientEntry
4702 Added new function silc_client_get_server_by_id to return
4703 the server entry by ID. Affected files are the
4704 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4706 * Do not create the channel in the Irssi SILC Client when issuing
4707 the JOIN command but when received the sucessful JOIN command
4708 reply. Otherwise the channel might get created even though we
4709 could not join it. The Affected file is
4710 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4712 * Fixed a channel joining bug in router. The router must also
4713 check the channel modes, invite and ban lists etc. when serving
4714 the JOIN command sent by normal server. Affected file is
4715 silcd/command.c. The router now resolves the client's
4716 information from the server who sent the JOIN command if it
4717 does not know it, and processes the JOIN command only after
4720 * Changed the SilcCommandCb to take new argument; void *context2.
4721 Affected file lib/silccore/silccommand.h
4723 The second argument in the command callbacks in the server now
4724 includes the SilcServerCommandReplyContext if the command was
4725 called as pending command callback from the command reply.
4726 Otherwise it is NULL. When called as pending the status of the
4727 command reply will be checked and if it was erronous the
4728 error will be sent to the original sender of the command.
4729 This way the client always receives the error messages even
4730 though the server was actually the one who received the error
4731 when it resent the command to router, for example. Affected
4732 files silcd/command[_reply].[ch].
4734 * Fixed sending WHOWAS command's error message to client if
4735 the requested client could not be found. It was missing.
4738 * Changed the CMODE and CUMODE commands reply arguments in the
4739 protocol specification. The Channel ID is now sent in both
4740 of the commands to identify the channel. Implemented this
4741 new feature to the client and server. Affected files
4742 lib/silcclient/command_reply.c and silcd/command.c.
4744 * Made better checks for invite and ban lists in the JOIN
4745 command in server. Affected file silcd/command.c.
4747 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4749 * The server now performs the incoming host IP/DNS lookup
4750 using the silc_socket_host_lookup and thus does not block
4751 the server anymore. Affected file silcd/server.c.
4753 * Completed the multi-thread support for SILC Scheduler in
4754 the lib/silcutil/silcschedule.c.
4756 * Fixed the configure.in.pre to detect the pthread correctly
4759 * Fixed a deadlock in silc_task_queue_wakeup in the file
4760 lib/silcutil/silctask.c.
4762 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4764 * Added new function silc_schedule_wakeup that is used in
4765 multi-threaded environment to wakeup the main thread's
4766 schduler. It needs to be used when a thread adds a new task
4767 or removes a task from task queues. After waking up, the
4768 scheduler will detect the task queue changes. If threads
4769 support is not compiled in this function has no effect.
4770 Implemented the wakeup mechanism to both Unix and WIN32
4771 systems. Affected files are lib/silcutil/silcschedule.[ch],
4772 lib/silcutil/unix/silcunixschedule.c and the
4773 lib/silcutil/win32/silcwin32schedule.c.
4775 * Added new function silc_task_queue_wakeup to wakeup the
4776 scheduler by the specified task queue. Affected file
4777 lib/silcutil/silctask.[ch].
4779 * The silc_socket_host_lookup_start now wakes up the scheduler
4780 after adding the timeout task. Affected file is
4781 lib/silcutil/silcsockconn.c.
4783 * The silc_socket_host_lookup is synchronous now if the threads
4784 support is not compiled in. However, the callback is still
4785 called asyncronously through the scheduler, anyway. Affected
4786 file lib/silcutil/silcsockconn.c.
4788 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4790 * Added new function silc_socket_host_lookup to perform
4791 asynchronous IP and FQDN lookups for the socket connection.
4792 Affected files lib/silcutil/silcsockconn.[ch].
4794 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4796 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4797 that may or may not compile the mutex support in.
4799 Changed the silc_mutex_alloc interface. It allocates the
4800 mutex now to the sent pointer and returns TRUE or FALSE.
4802 Affected file lib/silcutil/silcmutex.h.
4804 * Wrote the SILC Task Queue interface to support multi-threads.
4805 Affected file lib/silcutil/silctask.[ch].
4807 * Wrote the SILC Scheduler to support multi-threads. Affected
4808 file lib/silcutil/silcschedule.c.
4810 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4812 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4813 in lib/silcutil/win32/.
4815 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4817 * Defined SILC Mutex API and SILC Thread API and implemented
4818 them for Unix. Affected files are
4819 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4820 lib/silcutil/unix/silcunixmutex.c and
4821 lib/silcutil/unix/silcunixthread.c.
4823 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4825 * Fixed the silc_server_remove_clients_by_server's channel
4826 key re-generation. The hash table handling was incorrect
4827 and would not work with many channels. Affected file is
4830 * Fixed some memory leaks around the server code.
4832 * Rewrote the silc_server_get_users_on_channel to support IPv6
4833 based Client ID's. Affected file silcd/server.c.
4835 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4836 specification. However, a separate document must be written
4837 to define the detailed signing procedure and the payload
4838 associated with the flag. Defined the flag to the
4839 lib/silccore/silcchannel.h as well.
4841 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4843 * Changed the dynamic tables to static size tables in the
4844 lib/silccrypt/silchmac.c.
4846 * Removed GCC dependencies from the code. A patch by cras.
4848 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4850 * Do not show the error "Error receiving packet bla bla"
4851 in server if it really was not an error (-2 means that reading
4852 is pending). Affected file silcd/server.c.
4854 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4856 * Fixed a possible crash in silc_server_remove_clients_by_server
4857 in silcd/server.c. Fixed there also some memory leaks.
4859 * Fixed the silc_idlist_replace_client_id. It could replace
4860 wrong key in the hash table. Affected file silcd/idlist.c.
4862 * Do not check whether there are global users on the channel
4863 if the channel->global_users is FALSE. Affected functions
4864 silc_server_remove_from_one_channel and
4865 silc_server_remove_from_channels in silcd/server.c. Also,
4866 do not check if the removed client is local as we can be
4867 sure that global client was not removed from the channel
4868 and checking for global users is not needed.
4870 * The silc_server_remove_clients_by_server now re-generates
4871 the channel keys correctly for those channels that had
4872 clients removed from them. Affected file silcd/server.c.
4874 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4876 * Found the reason of random crashes in the server. We weren't
4877 ignoring the SIGPIPE signal (which can be sent in write())
4878 and it crashed the server. Affected file silcd/silcd.c.
4880 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4882 * Assure that sock->user_data is not NULL in the function
4883 silc_server_packet_send in silcd/packet_send.c.
4885 * Disconnect the remote connection if it could not be added
4886 to any ID lists in the server. The affected file is
4889 * Check in silc_server_packet_send[_real/dest] that the
4890 socket is not disconnecting and ignore the data if it is.
4891 Affected file silcd/packet_send.c.
4893 * Define inline to __inline on native WIN32 compilation.
4894 Affected file includes/silcwin32.h.
4896 * Added some explicit type casts for inline code since MSVC
4897 require them. Affected files lib/silcutil/silcbuffer.h,
4898 lib/trq/silcdlist.h and lib/trq/silclist.h.
4900 * Print warning in log files from now on if the packet
4901 decryption fails. Affected file silcd/server.c.
4903 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4905 * Changed the `say' client operation's interface to accept
4906 new `type' argument to indicate the type of the message sent
4907 by the library. The application may filter the library's
4908 messages according the type. The affected file is the
4909 lib/silcclient/silcapi.h.
4911 * Added two new functions to lib/silcclient/silcapi.h:
4912 silc_client_del_client and silc_client_del_client_by_id.
4913 Affected file lib/silcclient/idlist.c.
4915 * Moved the clientincludes.h from includes/ to silc/ and
4916 serverincludes.h from includes/ to silcd/.
4918 * The modes for the CMODE and CUMODE are now passed as
4919 uint32 for application with COMMAND_REPLY. The affected
4920 file is lib/silcclient/command_reply.c.
4922 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4924 * /WHOIS without arguments shows client's own information.
4925 Affected file lib/silcclient/command.c.
4927 * Changed PING to not accept any arguments. The specs
4928 says that client can ping only the connected server so
4929 requiring an argument is not needed. Affected file is
4930 lib/silcclient/command.c.
4932 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4934 * Fixed a fatal bug in private message sending and reception
4935 encryption and decryption when using private message keys.
4936 The implementation was incorrect and did not follow the
4937 specification. It causd that some of the message were
4938 lost since it did not use the sending and receiving keys
4939 as the protocol suggests. This has been fixed and will cause
4940 incompatibilities with older clients when sending private
4941 message encrypted with private message keys. Affected files
4942 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4943 and various other in Irssi SILC Client.
4945 Added `responder' boolean argument to the functions
4946 silc_client_add_private_message_key[_ske] to indicate when
4947 the key is added as responder or initiator of the key
4950 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4952 * Removed the silc_ske_check_version function and created
4953 a SilcSKECheckVersion callback. Added also a function
4954 silc_ske_set_callbacks that is now used to set all SKE
4955 callbacks. The callback functions are not given to
4956 the SKE functions anymore, but this function is used to
4959 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4961 * Added `silc_version' argument to the silc_client_alloc
4962 to define the version of the application for the library.
4963 The library will use the version string to compare it
4964 against the remote host's (usually a server) version
4965 string. Affected file lib/silcclient/silcapi.h
4967 * Added the KE protocol context to Key Agreement context
4968 in client library so that we can abort the SKE if it
4969 is in process when we get timeout. Affected file is
4970 lib/silcclient/client_keyagr.c.
4972 * Do not resolve the client ID forever if it returns in the
4973 first time that such client does not exist. This was done
4974 for example with private message. Affected file is
4975 lib/silcclient/client_prvmsg.c.
4977 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4979 * Do not add regex.h for WIN32. The affected file
4980 includes/silcincludes.h.
4982 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4983 not work yet 100%. It generates the DLL's automatically
4984 when compiling with --with-win32 under cygwin.
4986 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4988 * lib/contrib/regex.c is not compiled on WIN32.
4990 * Added silc_net_get_socket_opt function to the
4991 lib/silcutil/silcnet.h.
4993 * Added includes/silcwin32.h for WIN32 specific includes
4996 * Do not use ptime structure or any of the posix process
4997 functions on WIN32 in lib/silccrypt/silrng.c.
4999 * Added silc_gettimeofday to provide generic function
5000 for struct timeval on all platforms. Added the function
5001 to lib/silcutil/silcutil.h.
5003 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5005 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5006 library as they clearly belong there. As a plus side we
5007 can make the actual socket connection routines platform
5010 Added also new generic function silc_socket_read and
5011 silc_socket_write (that used to be silc_packet_[read/write].
5012 The implementation of these are platform specific.
5014 * Added WIN32 specific routines of silc_socket_[read/write]
5015 to lib/silcutil/win32/silcwin32sockconn.c.
5017 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5019 * Added preliminary support for native WIN32 compilation under
5020 cygwin (using the -mno-cygwin option for GCC) to the
5021 ./configure.in.pre. The --with-win32 now prepares the
5022 compilation for native WIN32.
5024 * Rewrote the SILC Scheduler interface in the file
5025 lib/silcutil/silcschedule.h. The scheduler is now context
5026 based and does not have anymore any global static scheduler.
5027 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5028 and created lib/silcutil/win32 directory for WIN32 based
5031 * Added Unix specific network routines to the
5032 lib/silcutil/unix/silcunixnet.c and the old
5033 lib/silcutil/silcnet.c includes now only generic routines.
5035 Added WIN32 specific network routines to the
5036 lib/silcutil/win32/silcwin32net.c.
5038 * Added Unix specific utility functions from the
5039 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5041 * Added WIN32 SILC Scheduler to the file
5042 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5045 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5047 * Do not handle JOIN notify in the server if the target client
5048 is not registered (idata->registered == FALSE). The affected
5049 file is silcd/packet_receive.c.
5051 * Update the nickrec->founder in event_cumode in the Irssi SILC
5052 client. Affected file irssi/src/silc/core/silc-channels.c.
5054 * Fixed the CUMODE_CHANGE notify handling in the server when
5055 server and router are announcing their clients on channels.
5056 Now the mode changes are saved and notified correctly. The
5057 affected file is /silcd/packet_receive.c.
5059 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5060 They really did not replace the cache entry in the ID Cache.
5061 Now they do that. Affected file silcd/idlist.c.
5063 * Fixed the KICK notify handling in the Irssi SILC client to
5064 update the channel records so that the kicked client does not
5065 appear to be on the channel. The affected file is
5066 irssi/src/silc/core/silc-channels.c.
5068 * Always update the conn->current_channel when executing command
5069 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5071 * Fixed the KILL notify handling in Irssi SILC client to remove
5072 the killed client on all channels.
5074 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Fixed the silc_parse_command_line to remove extra spaces
5077 from the start and end of the arguments. Affected file is
5078 lib/silcutil/silcutil.c.
5080 * Cancel and free any active protocol in the function
5081 silc_server_close_connection. Affected file silcd/server.c.
5083 * Cancel and free any active protocol in the function
5084 silc_client_close_connction. Affected file is
5085 lib/silcclient/client.c.
5087 * Do not execute the KILL command for clients that are in
5088 history (ie. they are not in the network). Affected file is
5091 * Fixed KILL notify handling, client does not crash anymore.
5092 Affected file irssi/src/silc/core/silc-channels.c.
5094 * Reduced the default packet buffer size from 2048 to 1024 in
5095 lib/silccore/silcpacket.c.
5097 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5098 counter to the SKE context that is incresed when the SKE library
5099 performs async operation outside the library. If the outside
5100 process frees the SKE context and FREED status will be set
5101 and the library will detect after the sync operation that the
5102 libary is freed. The affected files are
5103 lib/silcske/silcske[_status].[ch].
5105 * Resolve the client entry information in the function
5106 silc_client_channel_message to assure that NULL pointer is not
5107 passed as client entry to the application. */
5109 * Fixed the task timeout calculation to assure that there is
5110 never negative timeouts. The affected file is
5111 lib/silcutil/silcschedule.c.
5113 * Fixed the channel user mode notification sending in server.
5114 It was sent point-to-point to the router (or to server by router)
5115 but it needs to be destined to a channel. The routines now
5116 supports sending the channel user mode notifys to the channels
5117 when announcing clients and channels. Affected files are
5118 silcd/server.c and silcd/packet_receive.c.
5120 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5121 It did not actually replace the old channel entry in the cache.
5122 Affected file lib/silcclient/client_notify.c.
5124 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Fixed a possible crash in silc_packet_send_prepare. It now
5127 assures always that there is enough space in the buffer and
5128 at the tail area of the buffer (for MAC).
5130 Fixed the inbound buffer reallocation in silc_packet_read.
5131 It was old code and did not handle the reallocation correctly.
5134 The affected file is lib/silccore/silcpacket.c.
5136 * Fixed buffer overflow in silc_parse_nickname in the file
5137 lib/silcutil/silcutil.c.
5139 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * make install generates new server keys only if there is not
5144 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5147 Added check that if the NOREPLY is set then we will not send
5148 the away message. This avoids infinite loop of away messages
5149 if both clients are away. The affected file is
5150 lib/silcclient/client_prvmsg.c.
5152 * Fixed client crash if /NICK was given without arguments.
5153 Affected file lib/silcclient/command.c.
5155 * Server does not send the invite list in INVITE command back
5156 to the client if the list was not altered. Added this notion
5157 to the protocol spec as well. Affected file silcd/command.c.
5159 Fixed possible crash in INVITE command by checking the
5160 value of silc_server_get_client_route command.
5162 * Fixed the INVITE notify type handling. The arguments are now
5163 taken in correct order and client does not crash. The affected
5164 file is irssi/src/silc/core/silc-channels.c.
5166 Removed the "Inviting xxx to channel" message from the
5167 client library away and let the application handle it.
5168 Affected file lib/silcclient/command.c. Added that message
5169 to Irssi SILC client's message formats.
5171 * Fixed CMODE command crash in client. It now checks the
5172 amount of arguments correctly and does not crash. The affected
5173 file is lib/silcclient/command.c.
5175 * Do not create new channel automatically in silc_channels_join
5176 but check whether the channel by that name already exists.
5177 Affected file irssi/silc/core/silc-channels.c.
5179 * Do not send the SERVER_SIGNOFF to router if the disconnected
5180 entity was the router. Affected file silcd/server.c.
5182 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5183 SILC client as it was missing from there.
5185 Added the handling of the KICK notify to the Irssi SILC client
5186 as it was missing. Added "you have been kicked" message to
5187 Irssi SILC client's message modules formats.
5189 Added the handing of the KILL notify to the Irssi SILC client
5190 as it was missing. Added the kill message module formats
5193 The affected file is irssi/src/silc/core/silc-channels.c.
5195 * The router did not save the channel mode the server announced.
5196 Affected file silcd/packet_receive.c.
5198 * Fixed a possible crash in INFO command in server. If the
5199 server did not provide the server info it crashed. Affected
5200 file silcd/command.c.
5202 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Fixed the GETKEY command in the server to check also the
5205 global list. Otherwise the GETKEY would not work correctly
5206 in normal SILC server. Affected file silcd/command.c.
5208 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Fixed GETKEY crash, it crashed if the command did not succseed.
5212 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5215 is now real and not just an macro interface to GMP.
5217 Removed the entire GMP from the source tree and imported new
5218 NSS MPI library instead. Reason for removing GMP is that it is
5219 extremely large and compiles extremely slow. The NSS MPI
5220 is only a few files and compiles in less than 10 seconds.
5221 The speed is also about the same as GMP. The MPI is imported
5222 to lib/silcmath/mpi.
5224 If the system has GMP installed we will still use the GMP.
5225 If it is not then the NSS MPI will be compiled.
5227 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Merged a long nickname (127 characters long) crash bugfix from
5230 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5232 * Merged a freed memory reference bugfix from Irssi CVS tree.
5233 Affected file irssi/src/core/commands.c.
5235 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Added the server's public key sving and verification to the
5238 server when performing the SKE. This was missing and the
5239 remote server's (or router's) public key was accepted without
5240 checking whether we have it previously or trust it at all.
5241 Affected file silcd/protocol.c.
5243 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Check in the silc_server_timeout_remote if protocol is active
5246 and make sure that the protocol's final callback is called so
5247 that all memory if freed. Affected file silcd/server.c.
5249 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * silc_server_whois_send_reply crashed the server if the nickname
5252 was 127 characters long. Affected file silcd/command.c.
5254 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added sanity check to the silc_server_new_client. If the hostname
5257 is provided inside username then check that the provided hostname
5258 really is the same as the resolved one. If the hostname was not
5259 resolved then check it from the public key. Affected file is
5260 silcd/packet_receive.c.
5262 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5263 if the server disconnected us and the connection is not valid
5264 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5266 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5267 the library to the lib/silcutil/silcutil.[ch].
5269 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Close log file after open. Affected file
5272 lib/silcutil/silclog.c.
5274 * Check whether sock == NULL in silc_client_send_packet and return
5275 if it is. Affected file lib/silcclient/silcclient.c.
5277 * Check rec->entry == NULL in the Irssi SILC Client before
5278 sending the channel message. Affecte file is
5279 irssi/src/silc/core/silc-servers.c.
5281 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Merged a splitted window bugfix from Irssi CVS tree. The
5284 affected file is irssi/src/fe-text/textbuffer-view.c.
5286 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5287 It did not print nickname.
5289 * Improved the distributions system a bit.
5291 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5294 irssi/src/fe-text/gui-window.c.
5296 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5297 to in-active server. The affected file is
5298 irssi/src/silc/core/client_ops.c.
5300 * Resolve the client in USERS command reply if the entry does
5301 not have username resolved. The affected file is
5302 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5303 command to WHOIS command to really resolve stuff. The USERS
5304 is not used any more in any critical section so WHOIS can
5305 be used even though it might be slower than IDENTIFY.
5307 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5310 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Changed the protocol API a bit more consistent in the
5313 lib/silccore/silcprotocol.[ch].
5315 * Changed the following headers to ROBODoc format:
5317 lib/silccore/silcpayload.h
5318 lib/silccore/silcprotocol.h
5319 lib/silccore/silcsockconn.h
5321 All core library headers are now formatted.
5323 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Fixed a bug in Irssi SILC client; do not show that you are
5326 server/router operator if you really are not. Affected file is
5327 irssi/src/silc/core/client_ops.c.
5329 * Renamed silc_command_free_payload to silc_command_payload_free.
5330 Affected file lib/silccore/silccommand.h
5332 * Added silcmath.h to include the prototoypes of various routines
5333 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5336 * Changed the following headers to ROBODoc format:
5338 lib/silccore/silcchannel.h
5339 lib/silccore/silccommand.h
5340 lib/silccore/silcid.h
5341 lib/silccore/silcidcache.h
5342 lib/silccore/silcmode.h
5343 lib/silccore/silcnotify.h
5344 lib/silccore/silcpacket.h
5345 lib/silcmath/silcmath.h
5347 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Added checking to the server code not to start the server if
5350 ciphers and stuff are not configured properly. Affected files
5351 silcd/serverconfig.[h] and silcd/server.c.
5353 * Changed the layout of the header files of the public interfaces
5354 in the SILC libraries. The new layout supports ROBODoc
5355 documentation tool (and some others) so that it is easy to create
5356 a library reference manual. All the other headers and source
5357 code must still follow the CodingStyle document. Also source
5358 code must not include these ROBODoc stuffs, only the headers.
5359 Furthermore, all public interface headers must now be named
5360 by using `silc' prefix, example: silcapi.h, silccipher.h.
5361 Some files were renamed due to this. All the other headers
5362 must not be used as public interfaces. I will update the
5363 CodingStyle document later. Changed following headers, so far:
5365 lib/silcclient/silcapi.h
5366 lib/silccore/silcauth.h
5367 lib/silccore/silcprivate.h
5368 lib/silccrypt/silcdh.h
5370 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Removed silc_client_packet_send_flush from the client library
5375 as it is not needed. Affected file lib/silcclient/client.[ch].
5377 * Added printing of message of unresolved authentication method
5378 to the Irssi SILC client. Added it to the module formats.
5379 Removed the same message from the client library.
5381 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Added new distribution feature, DISTLABEL. Every distribution
5384 can define own preprocessor label that can be used in the
5385 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5386 file distributions, acconfig.h.pre and prepare.
5388 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Added Makefile.defines_int to include the actual definitions
5391 for Makefile.defines.in. Tested the new distribution system,
5392 created distributions and tested installation.
5394 * Added AWAY message printing to the Irssi SILC client. Added
5395 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5397 * Added SCONNECT command to call the SILC's CONNECT command.
5398 Cannot use CONNECT directly since Irssi uses that internally.
5399 Affected file irssi/src/silc/core/silc-servers.c.
5401 Added ACTION local command. It is same as ME command but takes
5402 the channel as mandatory argument.
5404 Rewrote some of the Irssi's help files to suite for SILC
5407 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Added Makefile.defines[.in] that should for now on be included
5410 in all Makefile.am file in the source tree. That file includes
5411 all common compilation definitions for SILC source tree.
5413 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Minor changes to the ./prepare script to change the package
5416 name according the distribution name to the configure.in.
5418 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Created new distribution system. Added file `distributions'
5421 that defines all the distributions that can be created out of
5422 the SILC source tree. The ./prepare script now reads that
5423 file to determine how to prepare the distributions. The
5424 first argument to the ./prepare is the name of the distribution
5425 and second is the version of the distribution. If given
5426 without arguments it creates the default (toolkit) distribution
5427 with the default version (defined in ./prepare).
5429 All Makefile.am files that are subject to the distributions
5430 are now named as Makefile.am.pre. These are ./Makefile.am
5431 and lib/Makefile.am. Others may be changed later.
5433 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Added invite list, ban list, some key management and connection
5436 error message printing to module formats in the Irssi SILC client.
5438 * Added new silc_client_set_away_message to set the away message
5439 that is back to the person who sent private message. The
5440 affected file lib/silcclient/silcapi.h and the
5441 lib/silcclient/client_prvmsg.c.
5443 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Fixed the private message sending in the Irssi SILC client,
5446 added local command KEY to the Irssi SILC client.
5448 Added key management and key agreement message formats to the
5449 irssi/src/fe-common/silc/module-formats.[ch].
5451 Added USERS (alias WHO) printing, server/router operator
5452 indication and LIST command printing to the module formats.
5454 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Fixed channel joining notify handling, cumode notify handling
5457 from Irssi SILC client.
5459 * Added SILC specific module-formats to the Irssi SILC client so
5460 that SILC specific message hilighting, colors etc is possible.
5461 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5463 Added channel mode, channel user mode, actions, notices,
5464 whois and whowas printing to the the module-formats.c.
5466 * Fixed a bug in channel deletion in the server. The channel
5467 is not left to the cache even if the channel founder auth mode
5468 is set when there are no users anymore on the channel. Affected
5469 file silcd/server.c.
5471 * The silc_net_localhost now resolves the entire hostname including
5472 the domain name. Affected file lib/silcutil/silcnet.c.
5474 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Changed the ask_passphrase client operation to be ascynchronous.
5477 It has now a completion callback and a context that the
5478 application must call after it has got the passphrase from
5479 the user. Affected files lib/silcclient/silcapi.h,
5480 lib/silcclient/protocol.c, lib/silcclient/command.c and
5483 Added SilcAskPassphrase callback that the application calls
5484 to deliver the passphrase to the library.
5486 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5487 The public key verification and especially a certificate
5488 verification is asynchronous procedure.
5490 Added new SILC_SKE_STATUS_PENDING status to indicate the
5491 request is pending and a callback will be called to finalize
5494 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5495 indicate that remote end did not send its public key (or
5496 certificate), even though we require it. Added check for this
5497 condition in the SKE. This was a security bug, now fixed.
5499 Defined new SilcSKEVerifyCbCompletion callback that is called
5500 when the verification process is completed.
5502 The affected files lib/silcske/silcske_status.h and
5503 lib/silcske/silcske.[ch].
5505 * Changed the verify_public_key client operation to be async
5506 as well. Defined SilcVerifyPublicKey callback that is used to
5507 indicate the success of the public key verification process.
5509 Changed the server and client to use the new async client
5512 * Changed the Irssi SILC client's internal scheduler to be called
5513 twice as many times as it used to be. As a result the client
5514 should be a bit faster now. Affected file is
5515 irssi/src/silc/core/silc-core.c.
5517 * Added support to Irssi SILC client of asynchronous public key
5518 verification and passphrase inquiry. Affected file is
5519 irssi/src/silc/core/silc-core.c.
5521 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Do not say "You have left channel %s" in client library.
5524 Moved it to the application. Affected files are
5525 lib/silcclient/command.c and silc/client_ops.c.
5527 * Fixed silc_client_get_clients. Command context was not
5528 duplicated and was freed memory in the callback. Affected
5529 file lib/silcclient/idlist.c.
5531 * Do not say "you are now talking..." on JOIN command in the
5532 client library. The appliation must handle it.
5534 * Do not say ".. changed topic to" in command reply in the
5535 client libary. The application must handle it.
5537 * Fixed TOPIC command sending in the client library.
5539 * Fixed a memory leak in silc_client_command_free in the file
5540 lib/silcclient/command.c.
5542 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Imported a modified version of Irssi client to the source tree.
5545 The Irssi will be used to create a new client called
5546 Irssi SILC. Imported to irssi/.
5548 Added silc_core_init_finish function to the Irssi. Affected
5549 file irssi/configure.in.
5551 A lot changes in the Makefile.ams around the irssi tree.
5553 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Do not rehash if the new size is same as the old size of the
5556 hash table, in the silc_hash_table_rehash*. The affected file
5557 lib/silcutil/silchashtable.c.
5559 * Replaced hash_table_del_by_context calls from the server
5560 (when channel->user_list and client->channels) to the
5561 hash_table_del as it is sufficient and faster.
5563 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Added silc_hash_table_list, silc_hash_table_get and the
5566 SilcHashTableList structure to provide an alternative way to
5567 traverse the hash table. The affected files are
5568 lib/silcutil/silchashtable.[ch].
5570 * Changed the server's idlist routines to use the hash table
5571 routines to optimize the code.
5573 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Replaced the client entry's `channel' list and channel entry's
5576 `user_list' list to hash tables for optimized lookup. Changed
5577 the code to use the hash table interface around the code.
5578 Affected file lib/silcd/idlist.[ch].
5580 * Added `auto_rehash' boolean argument to the function
5581 silc_hash_table_alloc to indicate whether the hash table should
5582 auto-rehash when it thinks is appropriate time. It will
5583 increase the hash table size if the there is twice as much
5584 entries in the table than the size of the table, and will
5585 decrease the size if there are twice as less entries than
5586 the size of the table.
5588 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5592 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * silc_idcache_purge_by_context deletes the entry now by context
5595 as it is supposed to do. Affected file lib/silccore/idcache.c.
5597 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5598 client is not anymore valid (WHOWAS givens the info) and not
5599 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5601 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Removed the `data' and `data_len' arguments from the ID Cache
5604 interfaces and added `name' argument. ID Cache does not handle
5605 anymore the binary data only a names associated with given ID.
5607 * When hashing a Client ID with silc_hash_id the entire ID is
5608 not hashed anymore, instead only the hash of the Client ID is
5609 hashed. This way we can access the Client ID from the cache
5610 with Client ID but with the hash of the ID (which is a hash of
5611 the nickname) as well without any difference in performance.
5613 Added also silc_idcache_find_by_id_one_ext to do one on one
5614 searching when we have the actual ID. Added also function
5615 silc_hash_client_id_compare. The affected files are
5616 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5618 * When hashing the name associated with a ID it is always done
5619 in lowercase. This way we can access the cache without worrying
5620 about case-sensitivity, even though, for example nicknames are
5623 * Fixed a bug in server with channel message sending. It put
5624 wrong ID type as destination ID. The affected file
5625 silcd/packet_send.c.
5627 * silc_idcache_del_by_context now deletes from all hash tables
5628 by context. Affected file lib/silccore/idcache.c.
5630 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Changed the client library to use the new ID Cache interface.
5633 Changes around the source tree.
5635 * Added silc_hash_table_rehash_ext to rehash with specific
5636 hash function. Affected file lib/silcutil/silchashtable.[ch].
5638 * Added silc_hash_string_compare to compare two strings in the
5639 hash table. Affected file lib/silcutil/silcutil.[ch].
5641 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Added new function silc_idcache_del_by_context into the
5644 lib/silccore/idcache.[ch].
5646 * Changed the server's ID list routines to use the new ID Cache
5647 interface. Changes around the source tree.
5649 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added silc_hash_table_del[_by_context]_ext functions in to the
5652 lib/silcutil/silchashtable.[ch].
5654 Removed silc_hash_table_find_all* routines and added new
5655 silc_hash_table_find_foreach to replace them.
5657 Added silc_hash_table_replace_ext function as extended
5658 replacing function. Separated the simple hash table interface
5659 from the extended hash table interface in the file
5660 lib/silcutil/silchashtable.h.
5662 * Fixed minor bugs and changed it to use some of the new
5663 hash table functions in lib/silccore/idcache.c
5665 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Added new function silc_hash_table_find_all to return all keys
5668 in the hash table by the specified key. As the hash table is
5669 collision resistant it also makes it possible to have several
5670 duplicate keys in the hash table. This function may be used to
5671 find all of the keys from the hash.
5673 Added user_context arguments to the SilcHashFunction,
5674 SilcHashCompare and SilcHashDestructor to deliver user specified
5677 Added new fuctions silc_hash_table_find[_all]_ext to do
5678 extended lookup with specified hash and compare functions and
5679 specified user contexts.
5681 Added new function silc_hash_table_add_ext to add the key
5682 with specified hash function and user context.
5684 Added new function silc_hash_table_foreach to traverse all
5685 entrys in the hash table. Added SilcHashForeach callback
5688 Added new function silc_hash_table_del_by_context to delete
5689 the entry only if the context associated with the key matches.
5691 Affected files are lib/silcutil/silchashtable.[ch].
5693 * Removed silc_hash_[server/client/channel]_id and added just
5694 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5695 silc_hash_id_compare to compare two ID's using as the hash table
5696 comparison function. Added also silc_hash_data to hash
5697 binary data and silc_hash_data_compare to compare it.
5699 * Removed silc_idlist_find_client_by_hash as it is not needed
5700 anymore. Affected file silcd/idlist.[ch].
5702 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5703 to use internally the SilcHashTable. The new ID Cache is a lot
5704 faster than the old one. Some of the ID Cache interface was also
5705 rewritten and obsolete and stupid functions were removed.
5707 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Added entry_count field to the SilcHashTable to keep the number
5710 of the entries in the table. Implemented the function
5711 silc_hash_table_rehash. Added new function
5712 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5714 Fixed a minor bug in silc_hash_table_free.
5716 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5717 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5718 into the lib/silcutil/silcutil.[ch].
5720 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Implemented a collision resistant hash table into the
5723 lib/silcutil/silchashtable[ch]. See the header and the source
5724 for the SilcHashTable API.
5726 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Merged dotconf version 1.0.2 into lib/dotconf.
5730 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Do not compile anything in lib/silcsim/* if the SIM support
5733 is not enabled. The tree should now compile without problems
5736 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Compiled the SILC under cygwin. Compiled and tested briefly
5739 without problems. More tests needed. The SIMs didn't compile
5742 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5744 * Fixed possible crash in silc_get_username in the
5745 lib/silcutil/silcutil.c.
5747 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Fixed a va_arg in silc/client_ops.c.
5751 * Oops, RC5 routines were named AES and caused some problems
5752 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5754 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * Added new SilcIDIP structure into the lib/silccore/id.h and
5757 replaced the old `ip' fields from all SILC ID's to that type.
5758 This is a step towards IPv6 support.
5760 The silc_id_get_len takes now the ID as an extra argument.
5761 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5762 both IPv4 and IPv6 based ID's.
5764 The affected files are lib/silccore/id.[ch] and other files
5765 around the tree using these routines.
5767 * Removed the ID length arguments in server from various
5768 silc_server_send_notify_* routines -> they are not needed
5771 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Fixed memory leak in silc_encode_pem_file in the file
5774 lib/silcutil/silcutil.c.
5776 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Check minor version as well in the SKE. Affected files are
5779 silcd/protocol.c and lib/silcclient/protocol.c.
5781 * Added --identifier option to the server so that an identifier
5782 can be when creating the public key for the server. Affected
5783 file is silcd/silcd.c.
5785 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5786 lib/silccrypt/silcpkcs.c.
5788 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Register default ciphers and stuff when using -C option with
5791 the server. Affected file sildc/silcd.c.
5793 * Put back the servers public key filename format, it is better
5794 than the new one. For now, the client keys are saved with the
5795 new filename format. The affected file silc/client_ops.c.
5797 * Implemented the Cipher API for the rest of the ciphers that
5798 did not implement it or implemented it the wrong way.
5800 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Register default ciphers and stuff when using the -S option
5803 in the client. Affected file silc/silc.c. Same also when
5804 creating new key pair with -C option.
5806 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Fixed the silc_verify_public_key client operation function to
5809 save the public keys differently. The fingerprint is now
5810 used as filename and not the hostname. This way also the
5811 client keys are saved uniquely and not with hostnames. The
5812 affected file is silc/client_ops.c.
5814 * Trimmed the silc_hash_fingerprint function to remove extra
5815 whitespaces from the end of the fingerprint. The affected
5816 file is lib/silccrypt/silchash.c.
5820 * Added silc_cipher_register_default function to register all
5821 default ciphers. It can be used when configuration files
5822 does not exist and the application does not want any specific
5823 ciphers in any specific order.
5825 The SilcDList is now used as silc_cipher_list dynamically
5826 allocated cipher list. Removed the static list all together
5827 and now all ciphers must be allocated to the dynamic list.
5828 The silc_cipher_alloc routine was changed to check only the
5831 All silc_cipher_* routines that used to return int returns
5834 The affected files lib/silccrypt/silccrypt.[ch].
5836 * The same thing was done to silc_hash_* as for silc_cipher_*
5837 routines. Affected files lib/silccrypt/silchash.[ch].
5839 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5840 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5841 Added also silc_pkcs_[un]register[_default] functions.
5842 Removed the data_context from the PKCS API.
5844 * Added silc_hmac_register_default function to register default
5845 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5846 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5847 to unregister all hmacs at once.
5849 * Register the default ciphers, hash functions, PKCSs and HMACs
5850 if client's configuration file does not exist. The affected
5853 * The client did not load the hash functions from the SIM
5854 modules at all. Added support for this. Affected file is
5855 silc/clientconfig.c.
5857 * When decoding public key with silc_pkcs_public_key_decode, check
5858 the supported algorithm only if PKCS are registered. Affected
5859 file lib/silccrypt/silcpkcs.c. The same was done with the
5860 silc_pkcs_private_key_decode.
5862 * Fixed the SILC List routines to keep the list always in order.
5863 It used to change the list's order when traversing the list but
5864 not it preserves the order. Affected file lib/trq/silclist.h.
5866 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Added the client library to use the SilcSocketConnection's
5869 reference counter (by silc_socket_dup) to prevent the bug that
5870 the socket object may be freed underneath async operation.
5872 * The name resolv library checking fixes in the configure.in.pre.
5875 * Created new version of the protocol drafts for future
5876 development. The -03 drafts are the ones that will be changed
5877 in the trunk now and the -02 will remain as they are.
5879 * Send list of CUMODE notifys to the router when announcing
5880 the channel users to the router. Affected file silcd/server.c.
5881 If the router receiving channel founder CUMODE for a channel
5882 that already has channel founder it will send CUMODE notify
5883 to the sender to remove the channel founder rights from the
5884 announced client. Affected file silcd/packet_receive.c.
5886 * The CUMODE notify may now use Server ID as well as the entity
5887 who changes the mode. Updated protocool specs.
5889 * Updated INSTALL and README files.
5891 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * New web pages in the http://silc.pspt.fi. The pages was
5898 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Implemented the [DenyConnectin] config section in the server.
5901 Added silc_server_config_denied_conn to check whether incoming
5902 connection is denied. Affected file silcd/serverconfig.[ch].
5904 * Do not check the ports when checking the incoming configuration
5905 data if the port is 0, meaning any. Affected file is
5906 silcd/serverconfig.c.
5908 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Fixed buffer overflow in silc_string_compare in the file
5911 lib/silcutil/silcutil.c.
5913 * Fixed double free in silc_server_command_leave in the file
5916 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Fixed the version checking in the server. Affected file is
5921 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Fixed the configuration data fetching when accepting new
5924 connections in the server. Affected file silcd/server.c.
5926 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5928 * Added `sender_entry' argument to the function
5929 silc_server_packet_relay_to_channel so that we can check
5930 whether some destination actually belongs to the same route
5931 the sender belongs (ie, we must not resend the packet to the
5932 sender). Affected file silcd/packet_send.[ch].
5934 * Added `servername' field to the SilcClientEntry in the server
5935 to hold the name of the server where client is from. Affected
5936 file is silcd/idlist.h.
5938 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Moved the channel message encrypting in the router betwen
5941 router connections from silc_server_channel_message to the
5942 silc_server_packet_relay_to_channel since we want to check
5943 whether we have anybody channel before encrypting anything.
5944 Affected files silcd/packet_[receive/send].c.
5946 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Fixed the [AdminConnection] server config section to support
5949 multiple entries. Affected file silcd/serverconfig.c.
5951 * Added support into the server to check the validity of the
5952 incoming connection before executing any KE or authentication
5955 * The connection configuration is now saved to the KE and
5956 connection auth protocol contexts and not fetched anymore in
5957 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5959 * The local hosts listenning address and port is also resolved
5960 now when starting the server. We want to have the socket object
5961 to include the real address and port for the listener. Added
5962 new function silc_net_check_local_by_sock into the files
5963 lib/silcutil/silcnet.[ch].
5965 * Fixed a broadcast bug in server -> do not broadcast if we
5968 * Fixed a routing bug. Do not route broadcast packets ever.
5969 Broadcast packets must be processed always and not routed since
5970 they may be destined to some other host than yourself and thus
5971 would get routed without no good reason. Affected file is
5974 * Added function silc_server_config_is_primary_route to check
5975 whether primary router connection has been configured (a router
5976 configuration that we are initiating). If there is not, we
5977 will assume that there is only two routers in the SILC network
5978 and we will use the incoming router connection as our primary
5979 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5981 * Changed the order of the broadcasting. Broadcast _after_ the
5982 packet has been processed not before. Affected file is
5985 * Fixed a [ClientConnection] parsing bug. The port was never
5986 parsed correctly thus resulting to port 0. Affected file
5987 silcd/serverconfig.c.
5989 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5990 argument and did not set the broadcast packet flag. Affected
5991 file silcd/packet_send.c. Fixed same bug in the function
5992 silc_server_send_notify as well.
5994 * If we receive NEW_ID packet for our own ID in the server, ignore
5997 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Removed the nickname from the Private Message Payload.
6002 Updated the code and the protocol specs.
6004 * Updated protocol specs for submitting to the IETF.
6006 * Tweaked the Random Number Generator a bit. Affected file
6007 lib/silccrypt/silcrng.c. Exported a new function
6008 silc_rng_[global]_add_noise which can be used to add more
6011 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Do not parse packets with different timeout when protocol
6014 is active -> may cause problem with rekey. Affected file
6017 * When server receives signoff notify it must not create
6018 new channel key if the client is on any channels since the
6019 sender of the signoff notify will create it.
6021 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Added printing of error messages during SKE protocol from the
6024 failure packet sent by server during SKE. Affected file
6027 * Removed the client's failure_callback handling with timeout
6028 and handle it immediately when received.
6030 * The SKE library returned wrong type in SUCCESS and FAILURE
6031 packets. They must be 32 bit MSB not 16 bit MSB.
6033 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Ok, rewrote the logic of the re-key and now it seems to work.
6036 I tested it on high traffic with frequent re-keys without
6037 problems. Added hmac_receive (and renamed hmac to hmac_send)
6038 in SilcClientConnection in lib/silcclient/client.h and
6039 in SilcIDListData in silcd/idlist.h. Also, removed the
6040 SilcPacketParserContext's cipher and hmac fields as they are
6041 not needed anymore and actually caused some problems when
6042 the ciphers and hmac's changed underneath the packet parser.
6044 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * If re-key protocol is active then process the incoming packets
6047 synchronously since we must assure that icoming packets encrypted
6048 with the old key is processed before the new keys is set to
6049 use. This is true other packets than for REKEY packets.
6050 Affected file silcd/server.c. The same was done to client library
6051 as well, affected file lib/silcclient/client.c.
6053 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Fixed bug in client and server to accept the force send if
6056 the packet is send from silc_[server/client]_packet_process
6057 function. Otherwise the packets are never delivered, oops.
6059 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Disable force sending of packets when REKEY protocol is active.
6062 We must assure that no packet is sent directly when rekey is
6063 performed. All packets must be sent through packet queue.
6064 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6065 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6066 function is silc_[server/client]_packet_send_real to check
6069 * Replaced the SIM paths from example config files to
6070 /usr/local/modules. Also, make install creates now
6071 /usr/local/silc/logs directory to hold all the SILC server
6074 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Made the configure.in.pre work on Solaris. Patch by salo.

6085 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * When MAC computation fails the silc_packet_decrypt returned 0
6088 even though it was supposed to return -1. Fixed this. The
6089 affected file is lib/silccore/silcpacket.c.
6091 * Do not replace the config files in /etc/silc (in make install)
6092 if they already exist. Affected file ./Makefile.am.
6094 * Do not send re-key packets immediately but through packet queue.
6095 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6097 * Changed silc_net_check_host_by_sock to return FALSE if the
6098 IP/DNS could not be resolved. Though, it returns the IP address
6099 now even if it could not resolve it (but returns also FALSE).
6100 Affected file lib/silcutil/silcnet.[ch].
6102 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Added silc_pkcs_decode_identifier to decode the public key's
6105 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6106 Added also silc_pkcs_free_identifier. Added also new context
6107 SilcPublicKeyIdentifier.
6109 * Added -S option to the silc client. It is used to dump the
6110 contents of the specified public key file.
6112 * Changed the PKCS api to return the public key length when
6113 setting the public key.
6115 * Fixed a fatal bug in the public and private key file loading.
6116 Affected file lib/silccrypt/silcpkcs.c.
6118 * Execute the packet parsing for client with zero (0) timeout
6119 if the protocol is active. Affected file silcd/server.c.
6121 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Made the key generation options to the silcd program. Added
6124 -C option, equivalent to client's option.
6126 * Added new [ServerKeys] config section to the server. It
6127 configures the server's public and private key.
6129 * Defined generic Public Key Payload into the protocol
6130 specification to send specific type of public keys and
6133 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6134 public key or certificate.
6136 * Implemented the GETKEY command to the server and to the
6137 client library and on user interface.
6139 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6175 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Do not ask whether user wants to use the negotiated private key
6178 for private messages, just use it. Affected file is
6179 silc/local_command.c.
6181 * Added `send_enc_key' and `enc_key_len' fields to the
6182 SilcIDListData structure since they are needed in the re-key

6206 * Changed _ALL_ unsigned long and unsigned int to uint32,
6207 unsgined short to uint16 in the source tree.
6209 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6210 not handle clients that has entry->data.registered == FALSE.
6211 They are not in the network anymore. Affected file is
6214 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6228 implemnted the printing of the SERVER_SIGNOFF info to the
6229 application. Affected file silc/client_ops.c.
6231 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6232 if the deleting was successful. Affected file silcd/idlist.[ch].
6234 * Added support for public key authentication in the connection
6235 authentication protocol in the client library. Affected file
6236 lib/silcclient/protocol.c.
6238 * Changed the server's silc_idlist_get_clients_by_* interface
6239 to support already allocated array so that new entries may be
6240 added to pre-allocated array. Affected file silcd/idlist.[ch].
6241 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6242 and command replies.
6244 * All command reply functions in the server now calls the
6245 pending command callback even if error occured. This way the
6246 error will be delivered to the client as well. Affected files
6247 silcd/command.c and silcd/command_reply.c.
6249 * Fixed INFO command to return local server's info if no server
6250 was provided. Affected file lib/silcclient/command.c.

6276 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6278 * Added SILC_UMODE_GONE mode to indicate when the client is not
6279 present in the SILC network. Added also support to the local
6280 command AWAY that will set this mode. Added support of showing
6281 "xxx is gone" in WHOIS command. The USERS command shows the
6282 gone status as well.
6284 * Fixed setting server and router operator privileges in the
6285 server's UMODE command. Affected file silcd/command.c.
6287 * Merged the SKE KE1 and KE2 payloads into one payload. The
6288 new KE payload is equivalent to the old KE2 payload.
6290 Cleaned up the SKE Start Payload parsing. It now uses the
6291 simple buffer unformatting to do the parsing. A lot faster
6294 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6295 to the SKE that is used to indicate whether both of the SKE
6296 parties should perform authentication. By default only the
6297 responder performs authentication. By setting this flag also
6298 the initiator must do authentication. By default it is unset
6299 since in normal SKE case, client to server connection, only
6300 the responder should do authentication. When doing SKE between
6301 two clients both should perform authentication. Updated the
6302 code and the protocol specs.
6304 * A little fix to IDENTIFY command in the server. Search the
6305 client first by hash not nickname. Affected file is
6308 * Fixed the silc_client_close_connection to support closing
6309 the client to client connections wihtout deleting too much
6310 data. Affected file lib/silcclient/client.c.
6312 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6313 are received if protocol used to be active but is not anymore
6314 the application would crash due to NULL pointer dereference.
6315 Affected files silcd/server.c and lib/silcclient/client.c.
6317 * Added `hash' field to the SilcClientConnection to include
6318 the hash function negotiated in the SKE protocol.
6320 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6321 to set the channel founder authentication data. A client can
6322 claim the founder rights later by providing the authentication
6323 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6324 This way the channel founder can regain the channel founder
6325 privileges even it is left the channel. This works only on
6326 local server and the client must be connected to the same
6327 server to be able to regain the founder rights. Updated the
6328 protocol specs accordingly.
6330 Added support to the CMODE command in the client to set the
6331 founder auth data. Read the README to see how to set it.
6333 Added support to the CUMODE command to claim the founder
6334 rights. Read the README to see how to do it.
6336 Added support for the founder authentication to the Channel
6337 Entry in the server. Affected file silcd/idlist.h.
6339 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6340 server's CMODE command. Affected file silcd/command.c.
6342 * Added the following new functions into lib/silccore/silcauth.[ch]:
6343 silc_auth_get_method and silc_auth_get_data.
6345 * The server now saves the remote hosts public key to the
6346 SilcIDListData pointer. Affected file silcd/protocol.c.
6348 * The normal server now does not remove the channel entry from
6349 the cache if the founder authentication data is set. It used
6350 to remove it if the founder was the last one on the channel on
6351 the server and left the channel. The auth data is saved and
6352 if the channel is re-joined later the old entry is used with
6353 the old auth data. Affected files silcd/command_reply.c and
6356 * Removed the `pkcs' field from the SilcIDListData structure
6357 in the server; it is not used. Affected file silcd/idlist.h.
6359 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6361 * Fixed packet processing on slow links. Partial packets were
6362 never re-processed because the incoming data buffer was cleared
6363 by the application. Application must not directly clear the
6364 sock->inbuf, the packet processing routines handle it. Fixed
6365 this in client library and in server.
6367 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Fixed the WHOIS and IDENTIFY send reply function to really
6370 check whether to send list or just one entry. Affected file
6373 * Cleaned up the LEAVE command's channel key distribution. The
6374 affected file silcd/command.c.
6376 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6377 can enforce the channel mode as well. In that case the ID
6378 includes the ID of the server. The code now enforces the
6379 mode change if the router have different mode than the server.
6381 * The notify client operation with CMODE_CHANGE notify can now
6382 return NULL client_entry pointer if the CMODE was not changed
6383 by client. Application must check for this.
6385 * Added <Server ID> argument to INFO command to support server
6386 info fetching by Server ID.
6388 * Added silc_server_announce_get_channel_users to get assembled
6389 packets of channel users of the specified channel. Affected
6390 file silcd/server.[ch].
6392 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6393 was freed underneath the ID Cache.
6395 * Re-announce clients when the server received CHANNEL_CHANGE
6396 notify from the router. Affected file silcd/packet_send.c.
6398 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6401 crashed since it did not handle the fact that there is no cipher
6402 called "3" and didn't check the error condition. Now fixed.
6404 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6405 flag. It can be used to send message requests.
6407 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Implemented the RESTART command in the client.
6411 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6412 notice type messages. Added notice printing to the user
6415 * The channel keys are not re-generated if the channel's mode
6416 is PRIVKEY, ie private key on the channel exists. Affected
6417 files silcd/server.c and silcd/command.c.
6419 * Fixed a little bug in channel message delivery when channel
6420 private keys are set in the server. Affected file is
6421 silcd/packet_send.c.
6423 * Changed the setting on channel->on_channel = TRUE from the
6424 silc_client_save_channel_key to the JOIN command reply. The
6425 key payload is not received if the private channel key is set.
6426 Affected file lib/silcclient/command_reply.c and the
6427 lib/silcclient/client_channel.c.
6429 * When the CMODE_CHANGE notify is sent and the channel private
6430 key mode is removed the channel key must be re-generated in
6431 other cells as well. Added this support for the router in the
6432 silcd/packet_receive.c.
6434 * Added new local command NOTICE to send notice message on
6435 channel. Affected file silc/local_command.[ch].
6437 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Added new local command ME to the client. It is used to send
6440 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6441 some action. Affected file silc/local_command.[ch].
6443 * Changed channel_message and private_message client operations
6444 to deliver the message flags to the application. Added also
6445 the `flags' arguments to the silc_client_send_channel_message
6446 and silc_client_send_private_message functions. Affected file
6449 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Redefined the Private Message Payload to support private message
6452 keys and to support the new private message flags. Updated
6453 the protocol specs. Flags makes it possible to have for example
6454 CTCP style messages.
6456 * Added new type SilcPrivateMessagePayload and defined an API
6457 for it in the lib/silcclient/silcprivate.[ch].
6459 * Tested private message private keys successfully. Tested the
6460 private message key set, unset and list commands with the new
6463 * Redefined the Channel Message Payload to include the channel
6464 message flags (equal with private message flags) to support
6465 for example CTCP style messages.
6467 * Defined some of the message (for channel and private message)
6468 flags. Updated the protocol specs and added the flags to the
6469 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6471 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Added SilcKeyAgreementStatus type to the key agreement routines
6474 to indicate the current status and error if one occured.
6475 The status types are defined in the lib/silcclient/silcapi.h.
6477 * Added new local command KEY that is used to set and unset private
6478 keys for channels, set and unset private keys for private messages
6479 with remote clients and to send key agreement requests and
6480 negotiate the key agreement protocol with remote client. The
6481 key agreement is supported only to negotiate private message keys,
6482 it currently cannot be used to negotiate private keys for channels,
6483 as it is not convenient for that purpose.
6485 * Fixed a minor pending callback setting bug in the function
6486 silc_client_get_client_by_id_resolve, now the function works.
6487 Affected file lib/silcclient/idlist.c.
6489 * Added function silc_net_get_local_port to get local bound
6490 port by socket. Added to lib/silcutil/silcnet.[ch].
6492 * Added `sockets' and `sockets_count' fields to the SilcClient
6493 object. They hold the sockets of the listenning sockets in
6494 the client. Listenning sockets may be for example the key
6495 agreement server. Affected file lib/silcclient/client.[ch].
6496 Added functions the silc_client_add_socket and the
6497 silc_client_del_socket. They are exported to the application
6500 * Added ~./silc/clientkeys to support other client's public keys.
6502 * Renamed verify_server_key client operation to verify_public_key
6503 and added one argument to indicate the type of the connection
6504 (server, client etc.).
6506 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Added silc_server_connection_auth_request to handle the
6509 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6510 silcd/packet_receive.[ch].
6512 * Added silc_server_send_connection_auth_request into the
6513 silcd/packet_send.c to send the connection auth request packet.
6515 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6518 * Fixed the public key authentication in responder side in the
6519 server. The `auth_data' pointer includes the SilcPublicKey
6520 not the path to the public key. Affected file silcd/protocol.c.
6522 * Implemented the public key authentication in the initiator side
6523 in the server. Affected file silcd/protocol.c.
6525 * Removed the [RedirectClient] config section from the server
6526 configuration. Is not needed and I don't want to implement it.
6528 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Cleaned up the CMODE command in the server. It now works
6531 correctly and supports all the modes defined in the protocol.
6532 Affected file is silcd/command.c.
6534 * Added `hmac_name' field to the SilcChannelEntry in the server
6535 to hold the default HMAC of the channel. It can be set when
6536 creating the channel (with JOIN command). Affected files
6539 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6540 type to indicate the change of the current cipher and hmac
6541 on the channel. Client can safely ignore the <cipher> argument
6542 (if it chooses to do so) since the CHANNEL_KEY packet will
6543 force the channel key change anyway. The <hmac> argument is
6544 important since the client is responsible of setting the new
6545 HMAC and the hmac key into use.
6547 * Fixed the CMODE command in the client library as well.
6549 * Tested CMODE command in router environment successfully.
6551 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * Show the version of the remote client (or server) when connecting
6554 to the server. It is logged to the log file. Affected file
6555 is silcd/protocol.c.
6557 * Fixed the KILLED notify handling in the client library. The
6558 client must be removed from all channels when receiving the
6561 Also, do not remove the client entry when giving the KILL
6562 command but when the KILLED notify is received.
6564 * Removed silc_idlist_find_client_by_nickname from the server.
6565 Not needed anymore. Affected files silcd/idlist.[ch].
6567 * Implemented the CHANNEL_CHANGE notify type handling to the
6568 server. Affected file silcd/server.c.
6572 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Added silc_server_send_notify_invite to send the INVITE
6575 notify between routers.
6577 * Implemented the INVITE command correctly to the server.
6579 * Implemented the INVITE notify type handling in the server.
6581 * Implemented the INVITE command to the client library and on the
6584 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Added function silc_server_get_client_resolve to find the
6587 client entry by ID from all ID lists and then resolve it
6588 (using WHOIS) if it cannot be found. Affected file is
6591 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Implemented the BAN command to the client library.
6595 * The JOIN command in the server now checks the invite list
6598 * Changed the silc_command_reply_payload_encode_va and the
6599 silc_command_payload_encode_va to support that if argument is
6600 NULL it ignores and checks the next argument. Affected file
6601 lib/silccore/silccommand.c.
6603 * Added silc_server_send_notify_ban to send the BAN notify
6604 type between routers.
6606 * Chaned the silc_notify_payload_encode to support that if
6607 argument is NULL it ignores and checks the next argument.
6608 Affected file lib/silccore/silcnotify.c.
6610 * Tested ban lists in router environment successfully.
6612 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Implemented BAN command to the server, in silcd/command.[ch].
6616 * Removed the BAN and INVITE_LIST modes from the CMODE command
6619 * Added function silc_string_match to regex match two strings.
6620 Affected files lib/silcutil/silcutil.[ch].
6622 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Redefined parts of the SilcChannelEntry in the server to support
6625 the new ban and invite lists.
6627 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Redefined the INVITE command. The same command can be used to
6630 invite individuals to the channel but also to manage the invite
6631 list of the channel (to add to and remove from the invite list).
6632 Updated the protocol specs.
6634 * Added new command SILC_COMMAND_BAN that can be used to manage
6635 the ban list of the channel. Updated the protocol specs.
6637 * Removed the channel modes: the SILC_CMODE_BAN and the
6638 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6639 in the CMODE command. The equivalent features are now available
6640 using INVITE and BAN commands. Updated the protocol specs.
6642 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6643 in the network about change in the current ban list. The notify
6644 type is not used by the client.
6646 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6647 support the invite lists.
6649 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Added new function silc_string_regexify that converts string
6652 including wildcard characters into regex string that can
6653 be used by the GNU regex library. Added into the file
6654 lib/silcutil/silcutil.[ch].
6656 Added silc_string_regex_combine to combine to regex strings
6657 into one so that they can be used as one regex string by
6658 the GNU regex library. Added into the file
6659 lib/silcutil/silcutil.[ch].
6661 Added silc_string_regex_match to match two strings. It returns
6662 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6664 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Imported GNU regex to the soruce tree into lib/contrib.
6667 Fixed some compiler warning from the regex.c.
6669 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Fixed MOTD command in the server to work in router environment.
6673 * Fixed the MOTD command in the client library to support
6674 the server argument in the command.
6676 * Added `nickname_len' argument to the silc_idlist_add_client
6677 in the server, as the `nickname' argument may be binary data
6680 * Added silc_idlist_get_channels to return all channels from
6683 * Implemented LIST command to the server. Affected file is
6686 * Implemented the LIST command to the client library and on the
6689 * Added [<user count>] argument to the LIST command reply.
6690 With private channels the user count is not shown.
6692 * Updated TODO and README.
6694 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * The client entry's data.registered must be TRUE even with
6697 global client entry on global client list. The data.registered
6698 is used to check whether the client is anymore in the network,
6699 for example with WHOWAS command so it must be valid.
6701 * Fixed the WHOWAS command in the server. It now actually works
6702 in router environment. Added function into silcd/command_reply.c
6703 silc_server_command_reply_whowas_save.
6705 * Added silc_idlist_purge function to the silcd/idlist.c
6706 to periodically purge the ID Cache.
6708 * Fixed INFO command in the server. It works now in router
6709 environment. Added <server name> argument to the INFO command
6710 reply. Updated the protocol specs.
6712 * Fixed minor bug in silc_idcache_purge to not purge if the
6713 expire value is zero.
6715 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6716 they were buggy because of the WHOWAS information.
6718 * Fixed local command MSG to handle the async resolving of
6719 the remote client properly. It used to fail the first MSG.
6720 Affected file silc/local_command.c.
6722 * Added `data_len' field to SilcIDCache context.
6724 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Update TODO. Todo in commands in the server.
6728 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6731 used by routers as broadcast packet to inform other routers
6732 about the changed user mode.
6734 Implemented the notify handling in the server. Affected file is
6735 silcd/packet_receive.c. Added the function
6736 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6738 * Added new generic Channel Payload and deprecated the New Channel
6739 Payload. The New Channel Payload is now the generic Channel
6742 * Added new argument `mode' to the silc_server_send_new_channel
6743 as it is required in the Channel Payload now.
6745 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6746 and created a new and real SilChannelPayload to represent the
6747 new generic Channel Payload. Implemented the encode/decode
6748 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6750 * Added silc_server_get_client_channel_list to return the list
6751 of channels the client has joined for WHOIS command reply.
6752 Affected file silcd/server.[ch].
6754 * Implemented the channel list sending in the WHOIS command reply
6755 in server and in the client.
6757 Implemented the channel list displaying on the user interface
6758 as well. Affected file silc/client_ops.c.
6760 * Added silc_channel_payload_parse_list to parse list of Channel
6761 Payloads. It returns SilcDList list of SilcChannelPayloads.
6762 Client for example can use this function to parse the list of
6763 channels it receives in the WHOIS command reply. The caller
6764 must free the list by calling silc_channel_payload_list_free.
6765 Affected files lib/silccore/silcchannel.[ch].
6767 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Added one new argument <user mode> to the WHOIS command reply
6770 to return the mode of the user in SILC. Updated the protocol
6773 Implemented it to the server and client.
6775 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6777 * Fixed the mode printing on the user interface on joining.
6778 Affected file silc/client_ops.c.
6780 * Implemented the UMODE command and user modes in general to the
6781 client library and to the user interface.
6783 * Implemented the UMODE command to the server.
6785 * The server now sends UNKNOWN_COMMAND error status if client sends
6786 unknown command. Affected file silcd/command.c.
6788 * All server commands now handle the command identifier the right
6789 way when sending the command reply to the client. The client can
6790 use to identify the command replies with the identifier.
6792 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Added silc_server_get_client_route to resolve the route to
6795 the client indicated by the client ID. Affected file is
6798 * Added silc_server_relay_packet as general function to relay
6799 packet to arbitrary destination. This deprecates functions
6800 like _send_private_message_key, _relay_notify etc. Affected
6801 file is silcd/packet_send.[ch].
6803 Removed silc_server_send_key_agreement,
6804 silc_server_send_private_message_key and
6805 silc_server_packet_relay_notify functions from the file
6806 silcd/packet_send.[ch].
6810 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6811 server. Affected file silcd/packet_receive.[ch].
6813 * Implemented the KILL command to the client. Implemented the
6814 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6815 Affected files lib/silcclient/command[_reply].c and
6816 lib/silcclient/client_notify.c. Implemented the KILL notify
6817 printing in the user inteface.
6819 * Fixed a lot silc_parse_nick memory leaks from the client
6820 library in the file lib/silcclient/command.c.
6822 * Changed the silc_server_send_notify_on_channels's `sender'
6823 argument from SilcSocketConnection to SilcClientEntry to
6824 check the sender as entry and not as connection object and not
6825 to send to the client provided as argument. The affected file
6826 is silcd/packet_send.[ch].
6828 * The notify packets that are destined directly to the client used
6829 to not to be processed by the server. Now changed that and the
6830 server processes all notify packets. After relaying the packet
6831 to the client the notify packet is processed in the server.
6833 * The silc_server_free_client_data now checks whether there is
6834 pending outgoing traffic for the client and purges the data to
6835 the network before removing the client entry.
6837 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6840 an client is killed from the SILC Network. Updated the protocol
6843 Added new function silc_server_send_notify_killed to the
6844 silcd/packet_send.[ch].
6846 * Added function silc_server_packet_relay_notify to relay notify
6847 packets that are destined directly to a client. In this case
6848 the server does not process the notify packets but merely relays
6849 it to the client. Affected file silcd/packet_send.[ch].
6851 Added also silc_server_packet_process_relay_notify to check
6852 whereto relay the notify. Affected file is
6853 silcd/packet_receive.[ch].
6855 * Implemented the KILL command to the server.
6859 * Added the backup schema desgined last fall to the protocol
6860 specs for everyone to see. The specification is in the
6861 *-spec-xx.txt draft and the packet type definitions for the
6862 backup routers is in *-pp-xx.txt draft. Thusly, added also
6863 new packet type SILC_PACKET_CELL_ROUTERS.
6865 * A big security problem in the implementation discovered. The
6866 signoff of an client did not cause new channel key generation
6867 which it of course should've done. The channel keys must be
6868 always re-generated when client leaves (or signoffs) the channel.
6869 The silc_server_remove_from_channels funtion now handles
6870 the channel key re-generation.
6872 * Added `sender' argument to the silc_server_send_notify_on_channels
6873 to not to send the client provided as argument. Affected file
6874 silcd/packet_send.[ch].
6876 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6878 * Implemented OPER and SILCOPER commands into the server and
6881 * Added silc_auth_verify and silc_auth_verify_data to verify
6882 the authentication directly from the authentication payload.
6883 It supports verifying both passphrase and public key based
6884 authentication. Affected file lib/silccore/silcauth.[ch].
6886 * Added `hash' field to the SilcIDListData structure. It is the
6887 hash negotiated in the SKE protocol. Affected file is
6890 * Slight redesigning of the SilcAuthPayload handling routines.
6891 Do not send SilcPKCS but SilcPublicKey as argument.
6893 * Implemented the public key authentication support to the
6894 serverconfig. The public key is loaded from the provided path
6895 and saved as authentication data to void * pointer. Thus,
6896 changed the unsigned char *auth_data to void *auth_data;
6898 * Fixed SHUTDOWN command to send the reply before the server
6899 is shutdown. :) Affected file silcd/command.c.
6901 * Fixed fatal bug in CONNECT command. The hostname was invalid
6902 memory and server crashed. Affected file silcd/command.c.
6904 * Fixed fatal bug in CLOSE command. The server_entry became
6905 invalid but was referenced later in the command. Affected file
6908 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Fixed fatal bug in failure packet handling. Server ignored
6911 the failure and thus crashed when it came.
6915 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6917 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6918 that the command may be executed only once in (about) 2 seconds.
6919 The old SILC_CF_LAG flag is same but allows command bursts up
6920 to five before limiting.
6922 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6923 server code. Various commands now includes the CF_LAG_STRICT
6924 flag to disallow any kind of miss-use of the command.
6926 * Fixed the silc_buffer_unformat to not to allocate any data
6927 if the length of the data is zero. It used to allocate the
6928 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6930 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6932 * Changed the format of AdminConnection configuration section
6933 in the server. Added username of the admin to the format.
6934 Affected files silcd/serverconfig.[ch].
6936 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6937 to return admin configuration data by host, username and/or
6940 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Implemented WHOWAS command to the server. Added the functions:
6944 silc_server_command_whowas_parse,
6945 silc_server_command_whowas_send_reply,
6946 silc_server_command_whowas_from_client and
6947 silc_server_command_whowas_from_server
6949 * Added <Client ID> argument to the WHOWAS command reply. Updated
6950 the protocol specs accordingly.
6952 * Implemented WHOWAS command and command_reply to the client
6955 Implemented the WHOWAS printing on the user interface.
6957 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Added new argument to the WHOWAS command reply, the real name.
6960 It is an optional argument. Updated the protocol specs.
6962 * Added SilcIDCacheDestructor callback that is registered when
6963 the SilcIDCache is allocated. The callback is called when
6964 an cache entry in the ID Cache expires, or is purged from the
6965 cache. Added into lib/silccore/idcache.[ch].
6967 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6968 to destruct the client entries when the cache entry expires.
6969 Other ID Cache's in server and in the client library ignores
6972 * If the ID Cache entry's `expire' field is zero then the entry
6973 never expires. Added boolean `expire' argument to the
6974 silc_idcache_add function in the lib/silccore/idcache.[ch].
6975 If it is TRUE the default expiry value is used.
6977 * Added silc_server_free_client_data_timeout that is registered
6978 when client disconnects. By default for 5 minutes we preserve
6979 the client entry for history - for WHOWAS command.
6981 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6983 * Added support to the server to enforce that commands are not
6984 executed more than once in 2 seconds. If server receives
6985 commands from client more frequently, timeout is registered
6986 to process the commands. Affected file silcd/command.c.
6987 Added new function silc_server_command_process_timeout.
6989 * Changed NICK_NOTIFY handling in client library to check that
6990 if the client's nickname was changed, so there is no need to
6991 resolve anything from the server.
6993 * Removed error printing from the WHOIS and IDENTIFY commands.
6994 If error occurs then it is ignored silently in the client library.
6995 The application, however, may map the received error to
6996 human readable error string. The application currently maps
6997 the NO_SUCH_NICKNAME error to string.
6999 * Made the command status message public to the application. Moved
7000 them from lib/silcclient/command_reply.c to
7001 lib/silcclient/command_reply.h. The application can map the
7002 received command status to the string with the
7003 silc_client_command_status_message function.
7005 * Added check to the server to check that client's ID is same
7006 as the Source ID in the packet the client sent. They must
7009 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Added dist-bzip hook to the Makefile.am to make bzip2
7012 compressed distributions.
7014 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Server now enforces the maximum length for the nickname and
7017 the channel as protocol specification dictates. 128 bytes for
7018 nickname and 256 bytes for channel name.
7020 * Moved the WHOIS printing to the application. The client libary
7021 does not print out the WHOIS information anymore, the application
7022 must do it. Renamed silc_client_command_reply_whois_print to
7023 the silc_client_command_reply_whois_save.
7025 The client's idle time is also sent to the application now, and
7026 the idle is shown on screen.
7028 * Added silc_client_command_reply_identify_save to save the
7029 received IDENTIFY entries.
7031 * Do not check for channel private keys in message sending and
7032 reception if the channel does not have the PRIVKEY mode set.
7033 Affected file lib/silclient/client_channel.c.
7035 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7038 just surfaced after chaning the JOIN procedure.
7040 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Added silc_client_get_clients_by_list to get client entries
7043 from Client ID list, that is returned for example by JOIN
7044 and USERS command replies. The application should use this
7045 function for example when JOIN command reply is received to
7046 resolve the clients already on the channel (library does not
7047 do that anymore as USERS command reply is not used in the JOIN
7048 procedure anymore). Affected files lib/silcclient/silcapi.h and
7049 lib/silcclient/idlist.c.
7051 * JOIN command reply and USERS command reply returns now SilcBuffer
7052 pointers instead of unsigned char pointers when returning
7053 the client list and mode list.
7055 * Added <Client ID> argument to the JOIN command reply, mainly
7056 for the server to identify for which client the command was
7057 originally sent. Updated protocol specs accordingly.
7059 * Added SilcDlist private_key pointer to the SilcChannelEntry
7060 in the client to support the channel private keys. Affected
7061 file is lib/silcclient/idlist.h.
7063 * Added SilcChannelPrivateKey argument to the function
7064 silc_client_send_channel_message so that application can choose
7065 to use specific private ke if it wants to. If it is not provided,
7066 the normal channel key is used, unless private keys are set.
7067 In this case the first (key that was added first) is used
7068 as the encryption key.
7070 * Implemented the support for channel private key handling.
7071 Implemented the following functions:
7073 silc_client_add_channel_private_key,
7074 silc_client_del_channel_private_keys,
7075 silc_client_del_channel_private_key,
7076 silc_client_list_channel_private_keys and
7077 silc_client_free_channel_private_keys
7079 Affected file lib/silcclient/client_channel.c.
7081 * Added the support for the private keys in the channel message
7082 sending and encryption and in the message reception and
7083 decryption. Affected funtions are
7084 silc_client_send_channel_message and silc_client_channel_message.
7086 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Added SKE's key verify callback to the client library's
7089 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7091 * Removed the statement that server (or router) must send USERS
7092 command reply when joining to the channel so that the client
7093 knows who are on the channel. Instead, the client list and
7094 client's mode list is now sent in the JOIN command reply to the
7095 client who joined channel. This is better solution.
7097 * Added function silc_server_get_users_on_channel and function
7098 silc_server_save_users_on_channel to the silcd/server.[ch].
7100 * Removed function silc_server_command_send_users from the
7103 * Do not show topic on the client library anymore. The topic is
7104 sent in the command reply notify to the application and the
7105 application must show the topic now.
7107 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Added client searching by nickname hash into the IDENTIFY and
7110 WHOIS commands in the server as they were clearly missing from
7111 them. Affected file is silcd/command.c.
7113 * Fixed a bug in private message receiving in the client library.
7114 The remote ID was freed and it wasn't supposed, now it is
7117 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Minor fix to the channel payload; allocate the data area, as it
7120 needs to be of specific length.
7122 * If the key agreement port is zero then the operating
7123 system will define the bound port. Affected files are
7124 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7126 * Added new function silc_channel_payload_decrypt into the file
7127 lib/silccore/silcchannel.[ch].
7129 * Moved the channel message etc, check from silc_packet_decrypt
7130 to applications. The library calls now a generic
7131 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7132 when the packet is either normal or special. This was done to
7133 allow more wide range of checking that was not allowed when
7134 the code was in library. Now applications can do virtually any
7135 checks to the packet and return to the library the decision how
7136 the packet should be processed. Affected files are
7137 lib/silccore/silcpacket.[ch].
7139 Added silc_server_packet_decrypt_check to the server and
7140 silc_client_packet_decrypt_check to the client library.
7142 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7143 to send with specified source and destination information.
7145 * Channel message delivery between routers was broken after the
7146 channel key distribution was fixed earlier. The channel key
7147 was used be to distributed to other routers as well which is not
7148 allowed by the protocol. Now this is fixed and channel keys
7149 really are cell specific and the channel message delivery between
7150 routers comply with the protocol specification.
7152 * Fixed various commands in server to check also the global list
7153 for the channel entry and not just the local list. The affected
7154 file silcd/command.c.
7156 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Added assert()s to buffer formatting and unformatting routines
7159 to assert (if --enable-debug) when error occurs. Affected
7160 file: lib/silcutil/silcbuffmt.c.
7162 * Changed to auto-reconnect to check whether the remote host is
7163 router and register the re-connect timeout if it is. It used
7164 to check that whether we are normal server, but router must do
7165 auto-reconnect with another router as well. Affected file
7168 * Removed the [<key len>] option from CMODE command as the cipher
7169 name decides the key length, nowadays. See the defined ciphers
7170 from the protocol specification.
7172 * Added [<hmac>] option to the CMODE command to define the HMAC
7173 for the channel. Added SILC_CMODE_HMAC channel mode.
7175 * Added [<hmac>] option for the JOIN command so that user can
7176 select which HMAC is used to compute the MACs of the channel
7179 * Added Hmac field to the Channel Message Payload. The integrity
7180 of plaintext channel messages are now protected by computing
7181 MAC of the message and attaching the MAC to the payload. The
7182 MAC is encrypted. Now, it is clear that this causes some
7183 overhead to the size of the packet but rationale for this is that
7184 now the receiver can verify whether the channel message decrypted
7185 correctly and also when private keys are set for the channel the
7186 receiver can decrypt the packet with several keys and check from
7187 the MAC which key decrypted the message correctly.
7189 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7190 lib/silccrypt/silccipher.[ch].
7192 * Added silc_hash_len to return the digest length into the
7193 lib/silcrypt/silchash.[ch].
7195 * Rewrote parts of Silc Channel Payload interface in the
7196 lib/silccore/silcchannel.[ch]. The encode function now also
7197 encrypts the packet and parse function decrypts it.
7199 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7201 * Fixed a minor formatting bug in the SKE's key material processing.
7202 It actually might have processed the keys wrong way resulting
7205 * Redefined the mandatory HMAC algorithms and added new algorithms.
7206 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7207 and hmac-md5 truncated to 96 bits. The mandatory is now
7208 hmac-sha1-96. Rest are optional (including the one that used
7209 to be mandatory). Rationale for this is that the truncated HMAC
7210 length is sufficient from security point of view and can actually
7211 make the attack against the HMAC harder. Also, the truncated
7212 HMAC causes less overhead to the packets. See the RFC2104 for
7215 * Added new [hmac] configuration section. The SKE used to use
7216 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7217 is of course wrong. The official names that must be proposed in
7218 the SKE are the ones defined in the protocol specification
7219 (hmac-sha1-96 for example). The user can configure any hmac
7220 using any hash function configured in the [hash] section. At
7221 least, the mandatory must be configured.
7223 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7225 * Added HMAC list to the SKE proposal list. It has now both
7226 hash algorithm list and HMAC list. This makes the protocol
7227 incompatible with previous versions. The SKE now seems to work
7228 the way it is supposed to work, for the first time actually.
7230 * Defined plain Hash algorithms to the protocol specification.
7233 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Implemented support for key agreement packets into the server.
7236 Added functions silc_server_key_agreement and
7237 silc_server_send_key_agreement. Other than these functions,
7238 server has nothing to do with this packet.
7240 * Added support for private message key packets into the server.
7241 Added functions silc_server_private_message_key and
7242 silc_server_send_private_message_key.
7246 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7247 called in the protocol's final callback instead in the END
7248 protocol state. This makes a little more sense and in the same
7249 time in client we can use the same protocol routines for normal
7250 key exchange and to key agreement packet handling as well.
7252 * Added to both client's and server's KE protocol context the
7253 SilcSKEKeyMaterial pointer to save the key material. We will
7254 bring the key material to the protocol's final callback by doing
7255 this. The final callback must free the key material.
7257 * Added SKE's packet_send callback into client's KE protocol
7258 context so that the caller can choose what packet sending function
7259 is used. This way we can use different packet sending when
7260 doing normal SKE when doing key agreement packet handling (in
7261 the key agreement packet handling we do not want to encrypt
7264 * Implemented the responder side of the key agreement routines
7265 in the client. The client can now bind to specified port and
7266 accept incoming key negotiation. The key material is passed
7267 to the application after the protocol is over.
7269 * Implemented the processing of incoming Key Agreement packet
7270 in the client. Added function silc_client_key_agreement to
7273 * Implemented the intiator side of the key agreement routines
7274 in the client. The client can now initiate key agreement with
7275 another remote client. The key material is passed to the
7276 application after the protocol is over.
7278 * Created client_keyagr.c to include all the key agreement
7281 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7282 SILC_TASK_CALLBACK except that it is not static.
7284 * Created client_notify.c and moved the Notify packet handling
7285 from the client.[ch] into that file.
7287 * Created client_prvmsg.c and moved all private message and
7288 private message key routines from the client.[ch] into that file.
7290 * Create client_channel.c and moved all channel message and
7291 channel private key routines from the client.[ch] into that file.
7293 * Changed silc_client_get_client_by_id_resolve to resolve with
7294 WHOIS command instead of IDENTIFY command, in the file
7295 lib/silclient/idlist.c.
7297 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7299 * Implemented the SKE's responder side to the Client library.
7301 * When FAILURE is received to the protocol do not trust it
7302 blindly. Register a timeout to wait whether the remote closes
7303 the connection as it should do it, only after that process the
7304 actual failure. This was changed to both client and server.
7306 * Added client_internal.h to include some of the structures
7307 there instead of client.h in lib/silcclient/.
7309 * Added function silc_task_unregister_by_callback to unregister
7310 timeouts by the callback function.
7312 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Some "Incomplete WHOIS info" errors has been appearing on the
7315 log files. Took away the entry->userinfo check from WHOIS
7316 reply sending. The entry->userinfo is now " " if client did not
7317 provide one. I thought this was fixed earlier but something
7318 is wrong still. Let's see if the error still appears.
7320 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7322 * Fixed a minor bug in the login when the channel key is
7323 re-generated in the server. It used to generate the key in
7324 wrong order and thus caused problems in the channel traffic.
7326 * Fixed a minor bug in channel key distsribution after
7327 KICK command. The key was not sent to the router even though
7330 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Added silc_ske_process_key_material_data as generic routine
7333 to process any key material as the SILC protocol dictates. The
7334 function is used by the actual SKE library but can be used by
7335 applications as well. This relates to the private message keys
7336 and the channel private keys since they must be processed the
7337 same way the normal SILC session keys. The protocol dictates
7338 this. Affected files: lib/silcske/silcske.[ch].
7340 Added also silc_ske_free_key_material to free the
7341 SilcSKEKeyMaterial structure.
7343 * Defined silc_cipher_set_key function to set the key for
7344 cipher without using the object's method function. The affected
7345 files: lib/silccrypt/silccipher.[ch].
7347 * Implemented silc silc_client_add_private_message_key,
7348 silc_client_add_private_message_key_ske,
7349 silc_client_del_private_message_key,
7350 silc_client_list_private_message_keys and
7351 silc_client_free_private_message_keys functions in the
7354 Added functions silc_client_send_private_message_key to send
7355 the Private Message Key payload and silc_client_private_message_key
7356 to handle incoming Private Message Key payload.
7358 * Added Cipher field to the Private Message Key payload to set
7359 the cipher to be used. If ignored, the default cipher defined
7360 in the SILC protocol (aes-256-cbc) is used.
7362 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7364 * Removed lib/silcclient/ops.h file.
7366 Redefined parts of the SILC Client Library API. Created new
7367 file silcapi.h that deprecates the ops.h file and defines the
7368 published Client Library API. Defined also private message key
7369 API and channel private key API into the file.
7371 This is the file that the application must include from the
7372 SILC Client Library. Other files need not be included by
7373 the application anymore.
7375 * Added new key_agreement client operation callback and also
7376 defined the Key Agreement library API for the application.
7378 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7381 is used by clients to request key negotiation between another
7382 client in the SILC network. If the negotiation is started it
7383 is performed using the SKE protocol. The result of the
7384 negotiation, the secret key material, can be used for example
7385 as private message key.
7387 Implemented the Key Agreement payload into the files
7388 lib/silccore/silauth.[ch].
7390 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * Redefined ciphers for the SILC protocol. Added some new ciphers
7393 and defined the key lengths for the algorithms. Changed the
7394 code accordingly. The default key length is now 256 bits.
7396 * Fixed SKE key distribution function silc_ske_process_key_material
7397 when the key length is more than 128 bits. The default key
7398 length in SILC is now 256 bits.
7400 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7401 to indicate unsupported algorithm.
7403 * Renamed rijndael.c to aes.c and all functions as well.
7405 * Fixed a long standing channel key setting bug in client library.
7406 Weird that it has never surfaced before.
7408 * Fixed bug in channel deletion. If the entire channel is removed
7409 then it must also delete the references of the channel entry
7410 from the client's channel list as the client's channel entry and
7411 the channel's client entry share same memory.
7413 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7415 * Implemented CONNECT and SHUTDOWN commands in the client.
7417 * Implemented CLOSE command to the client.
7419 * Added the function silc_idlist_find_server_by_name into the
7420 files silcd/idlist.[ch].
7422 Added the function silc_idlist_find_server_by_conn into the
7423 files silcd/idlist.[ch].
7425 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7427 * DIE command was renamed to SHUTDOWN. Updated the both code
7430 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7431 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7433 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7436 * Added function silc_server_create_connection function to create
7437 connection to remote router. My server implementation actually
7438 does not allow router to connect to normal server (it expects
7439 that normal server always initiates the connection to the router)
7440 so the CONNECT command is only good for connecting to another
7443 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7446 or some other client was kicked from the channel.
7448 Implemented the handling of the notify type to both client
7451 Implemented silc_server_send_notify_kicked to send the KICKED
7452 notify. It is used to send it to the server's primary router.
7454 * Implemented the KICK command into server and client.
7456 * Added `query' argument to the silc_idlist_get_client function
7457 to indicate whether to query the client from server or not if
7460 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7461 to indicate that the client is not channel founder.
7465 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7467 * Removed the rng context from SilcPacketContext structure and
7468 changed that the packet routine uses the Global RNG API.
7470 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Added support for quit message that client can "leave" on the
7473 channel when it quits the SILC. It is ditributed inside the
7474 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7476 Added silc_server_free_client_data that will take the
7477 signoff message as argument.
7479 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7481 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Updated parts of the protocol specification to keep it up
7486 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7489 payloads in one packet.
7491 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7492 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7493 use now the new List flag.
7495 * Also deprecated the following packet types: REPLACE_ID,
7496 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7498 * Added list support for Notify packet in server.
7500 * Added silc_server_send_notify_channel_change to send the
7501 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7502 the silc_server_send_replace_id.
7504 * Added silc_server_send_notify_nick_change to send the
7505 NICK_CHANGE notify type. Deprecates the function
7506 silc_server_send_replace_id.
7508 * Added silc_server_send_notify_join to send the JOIN notify type.
7509 Deprecates the function silc_server_send_new_channel_user.
7511 * Added silc_server_send_notify_leave to send LEAVE notify type.
7512 Deprecates the function silc_server_send_remove_channel_user.
7514 * Added silc_server_send_notify_cmode and
7515 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7516 types. Deprecates the silc_server_send_set_mode function.
7518 * Added SERVER_SIGNOFF notify type to indicate that server has
7519 quit. This means that all clients on the channel from that
7520 server will drop. This can be also used when netsplit happens.
7522 Deprecated REMOVE_ID packet type since it is not needed anymore
7525 Added silc_server_send_notify_server_signoff to send the
7526 SERVER_SIGNOFF notify type. Deprecates the function
7527 silc_server_send_remove_id.
7529 Added also silc_server_send_notify_signoff to send the
7530 SIGNOFF notify type.
7532 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7533 SILC protocol from this day on. Changed the protocol
7534 specification as well.
7536 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7537 notify type. It is used between routers to notify about
7538 topic changes on a channel.
7540 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7543 * Partly updated the protocol specification to comply with the
7544 changes now made. It is still though a bit outdated.
7546 * The JOIN notify type now takes one extra argument <Channel ID>.
7547 The packet used to be destined to the channel but now the
7548 JOIN type may be sent as list thus it is impossible to
7549 destine it to any specific channel. By adding this argument
7550 it is again possible.
7552 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7554 * Added CREDITS file. The CHANGES and CREDITS file will appear
7555 in the distribution as well.
7557 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7560 types in the server's silcd/packet_receive.c.
7562 * Implemented CMODE and CUMODE to work in router environment.
7564 * Fixed minor encoding and decoding buglet from the
7565 lib/silccore/silcmode.c.
7567 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7570 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7572 * Changed all SilcConfigServer* and silc_config_server* to
7573 SilcServerConfig* and silc_server_config*, respectively.
7576 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7578 * Associated the ID (client or server ID) to the Authentication
7579 Payload to avoid any possibility of forging. Updated the
7580 protocol specification and the code accordingly.
7582 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7584 * The RSA key length is now save to the RsaKey context in the
7585 key generation process in lib/silccrypt/rsa.c. The key length
7586 is now used to figure out the maximum size of the block allowed
7587 to be encrypted/signed.
7589 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7590 is equivalent to the silc_mp_mp2bin but does not allocate any
7593 * Changed silc_mp_mp2bin API to take length argument. If it is
7594 non-zero then the buffer is allocated that large. If zero, then
7595 the size is approximated using silc_mp_sizeinbase, which however
7598 * Created Global RNG API which is global RNG that application can
7599 initialize. After initializing, any routine anywhere in the
7600 code (including library) can use RNG without allocating a new
7601 RNG object. This was done to allow this sort of use of the
7602 RNG in code that has no chance to allocate RNG object. All
7603 applications currently allocate this and many routines in the
7604 library use this. Affected file lib/silccrypt/silcrng.[ch].
7606 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7607 it to use the Global RNG API.
7609 * Defined Authentication Payload into protocol specification that
7610 is used during SILC session to authenticate entities. It is
7611 used for example by client to authenticate itself to the server
7612 to obtain server operator privileges.
7614 Implemented this payload into the lib/silccore/silcauth.[ch].
7615 Implemented also routines for public key based authentication
7616 as the new protocol specification dictates.
7618 Moved definitions of different authentication methods from
7619 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7621 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7622 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7623 silc_pkcs_verify_with_hash functions into the file
7624 lib/silccrypt/silcpkcs.[ch].
7626 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * The client entry's userinfo pointer must be always valid.
7629 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7630 will fail since it requires the userinfo. Now, the userinfo
7631 is allocated as "" if actual userinfo does not exist. Actually,
7632 it must exist and it is totally Ok to drop client connections
7633 that does not announce the userinfo. However, we will make
7634 this workaround for now.
7636 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7637 to return the remote port by socket.
7639 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7641 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7642 SILC_SERVER_PENDING_EXEC and added an new macro
7643 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7644 data or when error occurs while processing the pending command.
7646 Added new argument `destructor' into silc_server_command_pending
7647 and to the SilcServerCommandPending object. This destructor is
7648 now called after calling the pending callback or if error occurs
7649 immediately. If error occurs the actual pending callback won't
7650 be called at all - only the destructor. The destructor may be
7651 NULL if destructor is not needed.
7653 All this applies for client library code as well. Similar
7654 changes were made there as well for the pending commands.
7656 In the client, the application must now allocate the
7657 SilcClientCommandContext with the silc_client_command_alloc
7660 * Added reference counter to the SilcServerCommandContext. Added
7661 function silc_server_command_alloc and silc_server_command_dup
7664 Same type of functions added to the client library for the same
7667 * Removed the cmd_ident from IDListData away since it is now
7668 global for all connections. It is the command identifier used
7669 in command sending and with pending commands. The affected file
7672 * Added reference counter to the SilcSocketConnection objecet to
7673 indicate the usage count of the object. The object won't be
7674 freed untill the reference counter hits zero. Currently only
7675 server uses this, and client ignores it. The client must be
7676 set to use this too later. The affected files are
7677 lib/silccore/silcsockconn.[ch]. Added also the function
7678 silc_socket_dup to increase the reference counter.
7680 This was mainly added because it is possible that the socket
7681 is removed underneath of pending command or other async
7682 operation. Now it won't be free'd and proper DISCONNECTING
7683 flags, etc. can be set to avoid sending data to connection that
7684 is not valid anymore.
7686 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7687 the connection. After that it sets SILC_SET_DISCONNECTED.
7688 It is, however, possible that the socket data is not still freed.
7689 The silc_server_packet_process now checks that data is not
7690 read or written to connection that is DISCONNECTED. The socket
7691 get's freed when the reference counter hits zero.
7693 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7695 * Changed the client operation API: channel_message operation's
7696 `sender' is now the client entry of the sender, not the nickname
7697 and the `channel' is the channel entry, not the channel name.
7699 In the private_message operation the `sender' is now also the
7700 client entry of the sender not the nickname.
7702 Affected file is lib/silcclient/ops.h and all applications
7703 using the client operations.
7705 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Moved the calling of ops->connect() from connect_to_server_final
7708 into receive_new_id functin since that is the point when the
7709 client is actually allowed to send traffic to network. The
7710 affected file is lib/silcclient/client.c.
7712 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7714 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7715 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7716 (if needs broadcasting) instead of broadcasting the packets one
7717 by one which would make a burst in the network traffic.
7719 * Added `broadcast' argument to the functions in silcd/server.[ch]
7720 silc_server_create_new_channel[_with_id] to indicate whether
7721 to send New Channel packet to primary router.
7723 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7725 * Added new function into the silcd/server.[ch] files:
7726 silc_server_create_new_channel_with_id to create new channel with
7727 already existing Channel ID.
7729 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7730 lib/silccore/silcpacket.h. This packet is used t send list of
7731 Set Mode payloads inside one packet. Server uses this to set
7732 the modes for the channels and clients on those channels, that it
7733 announced to the router when it connected to it. The protocol
7734 specification has been updated accordingly.
7736 * The silc_server_new_channel did not handle the packet coming
7737 from normal server as it normally does not send that. However,
7738 when it announces its channels it does send it. Implemented
7739 the support for that.
7741 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7742 into the file lib/silccore/id.h.
7744 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7746 * Fixed memory leaks in the functions silc_idlist_del_client,
7747 silc_idlist_del_channel and silc_idlist_del_server in the file
7748 silcd/idlist.c. All of those leaked like a sieve.
7750 * Fixed some small memory leaks in the client's function
7751 silc_client_notify_by_server.
7753 * Added functions into silcd/server.c: silc_server_announce_clients,
7754 silc_server_announce_channels and silc_server_announce_server.
7755 These functions are used by normal and router server to announce
7756 to its primary router about clients, channels and servers (when
7757 router) that we own. This is done after we've connected to the
7760 These functions effectively implements the following packet types:
7761 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7762 and SILC_PACKET_NEW_ID_LIST.
7764 * Added new functions into the silcd/packet_receive.[ch]:
7765 silc_server_new_id_list, silc_server_new_channel_list and
7766 silc_server_new_channel_user_list to handle the incoming
7767 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7769 * Added support of changing Channel ID in the function
7770 silc_server_replace_id. If the server that announces a channel
7771 to the router already exists in the router (with same name but
7772 with different Channel ID), router is responsible to send
7773 Replace ID packet to the server and force the server to change
7774 the Channel ID to the one router has.
7776 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7777 client that the Channel ID has been changed by the router. The
7778 normal server sends this to the client. Client must start using
7779 the new Channel ID as the channel's ID.
7781 Implemented handling of this new type into lib/silcclient/client.c
7782 into the function silc_client_notify_by_server.
7784 * Added new function silc_idlist_replace_channel_id into the files
7785 silcd/idlist.[ch] to replace the Channel ID.
7787 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7789 * Call silc_server_command_identify_check always when processing
7790 the IDENTIFY command in silcd/command.c
7792 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7794 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7795 send keepalive packets. The packet can be sent by clients,
7796 servers and routers.
7798 Added function silc_socket_set_heartbeat into the file
7799 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7800 If not set, the heartbeat is not performed. The actual
7801 heartbeat is implemented in the low level socket connection
7802 library. However, application is responsible of actually
7805 Added silc_server_send_heartbeat to send the actual heartbeat
7806 packet into silcd/packet_send.[ch]. Server now performs
7807 keepalive with all connections.
7809 * Added silc_task_get_first function into lib/silcutil/silctask.c
7810 to return the timeout task with shortest timeout. There was a bug
7811 in task unregistration that caused problems. TODO has been
7812 updated to include that task system must be rewritten.
7814 * The client library will now resolve the client information when
7815 receiving JOIN notify from server for client that we know but
7816 have incomplete information.
7818 * Rewrote parts of silc_server_remove_from_channels and
7819 silc_server_remove_from_one_channel as they did not remove the
7820 channel in some circumstances even though they should've.
7822 * Encryption problem encountered in server:
7824 The LEAVE command used to send the Channel Key packet to the
7825 router immediately after generating it. However, the code
7826 had earlier sent Remove Channel user packet but not immediately,
7827 ie. it was put to queue. The order of packets in the router
7828 was that Channel Key packet was first and Remove Channel User
7829 packet was second, even though they were encrypted in the
7830 reverse order. For this reason, MAC check failed. Now, this
7831 is fixed by not sending the Channel Key packet immediately but
7832 putting it to queue. However, this is more fundamental problem:
7833 packets that are in queue should actually not be encrypted
7834 because packets that are sent immediately gets encrypted
7835 actually with wrong IV (and thus MAC check fails). So, packets
7836 that are in queue should be encrypted when they are sent to
7837 the wire and not when they put to the queue.
7839 However, the problem is that the current system has not been
7840 designed to work that way. Instead, the packet is encrypted
7841 as soon as possible and left to the queue. The queue is then
7842 just purged into wire. There won't be any fixes for this
7843 any time soon. So, the current semantic for packet sending
7846 o If you send packet to remote host and do not force the send
7847 (the packet will be in queue) then all subsequent packets to the
7848 same remote host must also be put to the queue. Only after the
7849 queue has been purged is it safe again to force the packet
7852 o If you send all packets immediately then it safe to send
7853 any of subsequent packets through the queue, however, after
7854 the first packet is put to queue then any subsequent packets
7855 must also be put to the queue.
7857 Follow these rules and everything works fine.
7859 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7861 * Added new function silc_server_remove_clients_by_server to
7862 remove all client entries from ID list when the server connection
7863 is lost. In this case it is also important to invalidate all
7864 client entires as they hold the invalid server entry. This
7865 fixes fatal bug when server has lost connection and will reconnect
7868 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7870 * Made some sanity checks to silc_server_daemonise like to check
7871 whether the requested user and group actually exists.
7873 * Added sanity check to SKE's silc_ske_responder_finish to check
7874 that the public and private key actually is valid.
7876 * Invalidate the client's nickname when receiving Replace ID
7877 packet and the Client ID is being replaced. This means that the
7878 server will query the nickname if someone needs it (client)
7881 * Sort the ID Cache in client library when the ID Cache data
7882 has changed (needs sorting).
7884 * Do not allow for SILC client to create several connections to
7885 several servers. The client does not support windows right now
7886 and generating multiple connections causes weird behaviour.
7888 Irssi-silc client does support windows and can handle several
7889 connections without problems, see: www.irssi.org and SILC plugin.
7891 * Fixed some places where client was added to the IDList. The
7892 rule of thumb is following (in order to get everything right):
7893 If the client is directly connected local client then the
7894 `connection' argument must be set and `router' argument must be
7895 NULL to silc_idlist_add_client function. If the client is not
7896 directly connected client then the `router' argument must
7897 bet set and the `connection' argument must be NULL to the
7898 silc_idlist_add_client function.
7900 * The funtion silc_server_packet_send_local_channel actually did
7901 not check whether the client was locally connected or not. It
7902 does that now. Fixed a bug related to LEAVE command.
7904 * Fixed Remove Channel User payload parsing bug in server's
7905 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7907 * The server's silc_server_save_channel_key now checks also the
7908 global ID list for the channel as it might not be in the local
7909 list. Fixed a bug related to LEAVE command.
7911 * Is this the end of the [<unknown>] buglet that has been lurking
7912 around for a long time? A little for loop fix in server's
7913 silc_server_command_whois_parse that is used by both IDENTIFY
7914 and WHOIS command. At least, this was a clear bug and a cause
7915 of one type of [<unknown>] buglet.
7917 * WHOIS and IDENTIFY commands call the function
7918 silc_server_command_[whois/identify]_check function even if
7919 we are not router server.
7921 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7923 * Added --with-gmp configuration option. If set the GMP
7924 is always compiled in the SILC source tree. If not set then
7925 it is checked whether the system has the GMP3 installed. If
7926 it has then the GMP won't be compiled (the system's headers
7927 and library is used), if it doesn't have it then the GMP is
7928 compiled in the SILC source tree.
7930 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7932 * Changed RSA private exponent generation to what PKCS #1
7933 suggests. We try to find the smallest possible d by doing
7934 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7935 not security fix but optimization.
7937 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7939 * Added new config entry [Identity] to fork the server and run
7940 it as specific user and group. A patch from Bostik.
7942 * Imported Dotconf configuration library into lib/dotconf.
7943 This will be used to create the SILC configuration files later.
7944 It will appear in the distsribution after this commit.
7946 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7948 * A big code auditing weekend happening. Auditing code for
7949 obvious mistakes, bugs and errors. Also, removing any code
7952 Removed files for being obsolete:
7954 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7955 inline in the file lib/silcutil/silcbuffer.h)
7957 o lib/silcutil/silcbufutil.c (the header has inline versions)
7959 Changed code to fix possible error conditions:
7961 o The buffer formatting routines now check that the destination
7962 buffer really has enough space to add the data. This applies for
7963 both buffer formatting and unformatting
7964 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7965 unformatting was changed to accomodate following rules:
7966 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7967 sent to the function while XXX_*STRING will not allocate or copy
7968 the data into the buffer. Instead it sets the pointer from the
7969 buffer into the pointer sent as argument (XXX_*STRING used to
7970 require that the pointer must be allocated already). This change
7971 makes this whole thing a bit more consistent and more optimized
7972 (note that the data returned in the unformatting with XXX_*STRING
7973 must not be freed now). The routines return now -1 on error.
7975 o Tried to find all code that use buffer_format and buffer_unformat
7976 and added return value checking to prevent formatting and
7977 especially unformatting errors and possible subsequent fatal
7980 o Changed ske->x and ske->KEY to mallocated pointers in
7981 lib/silcske/silcske.h. Fixed possible data and memory leak.
7983 o Added return value checking to all *_parse* functions. Fixed
7984 many memory leaks as well.
7986 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7987 so that buffer overflows would not happen. All code now also
7988 checks the return value as it can fail.
7990 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7992 * Added reconnection support to server if the normal server looses
7993 its connection to the router (for example if router is rebooted).
7994 The server performs normal reconnection strategy implemented
7995 to the server. Affected file silcd/server.c.
7997 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7999 * Added new packet type SILC_PACKET_SET_MODE that is used to
8000 distribute the information about changed modes (for clients,
8001 channels and clients channel modes) to all routers in the
8002 network. Updated the protocol specification accordingly.
8004 Added functions into silcd/packet_send.c and
8005 silcd/packet_receive.c: silc_server_send_set_mode,
8006 silc_server_set_mode.
8008 Added new files silcmode.[ch] into lib/silccore that implements
8009 the encoding and decoding of Set Mode Payload. Added new type
8010 SilcSetModePayload. Moved the definitions of different modes
8011 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8013 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * Oops, a little mistake in server's connection authentication
8016 protocol. The protocol is not ended with FAILURE but with
8017 SUCCESS if the authentication is Ok. :) Affected file is
8020 * Implemented NICK_CHANGE notify handling in server in the file
8021 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8022 the local clients on the channel. After the changing nickname
8023 in router environment snhould work and the [<unknown>] nickname
8024 should appear no more.
8026 The silc_server_replace_id function that receives the Replace ID
8027 payload now sends the NICK_CHANGE notify type also in the file
8028 silcd/packet_receive.c
8030 * Changed WHOIS and IDENTIFY command to support the maximum amount
8031 of arguments defined in protocol specs (3328 arguments). This
8032 fixed a bug that caused problems when there were more than three
8035 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8037 * Added extra parameter, command identifier, to the
8038 silc_client_send_command so that explicit command identifier
8041 Changed that ID list routines uses specific command identifier
8042 when sending WHOIS/IDENTIFY requests to the server so that they
8043 can be identified when the reply comes back.
8045 Affected files lib/silcclient/command.[ch],
8046 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8048 * Added `sender' argument to silc_server_packet_send_to_channel
8049 to indicaet the sender who originally sent the packet to us
8050 that we are now re-sending. Ignored if NULL. Affected file
8051 silcd/packet_send.[ch].
8053 * Added some server statistics support in silcd/server_internal.h
8054 SilcServerStatistics structure and around the server code. Also
8055 send some nice statistics information when client is connecting
8058 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8060 * Fixed channel ID decoding in server's JOIN command reply in
8061 silcd/command_reply.c
8063 * Fixed braodcasting of replace ID payload to not to send it if
8064 we are standalone server in silcd/packet_receive.c.
8066 * Fixed all channel message sending routines to not to send
8067 packets to clients that has router set, since they are routed
8068 separately in the same function earlier. Affects file
8069 silcd/packet_send.c and all channel packet sending functions.
8071 * In USERS reply, res_argv[i] are not allocated, the table
8072 is allocated. Thus changed that free the table, not its
8075 * In server's whois_check and identify_check if the client is
8076 locally connected do not send any WHOIS commands - they are not
8079 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8081 * Fixed some minor bugs in client when sending WHOIS command. The
8082 arguments was in wrong order.
8084 * Removed statis function add_to_channel from server in
8085 silcd/command.c that was previously used with the joining but
8088 * Tested USERS command in router environment successfully with two
8089 routers, two servers and two clients.
8091 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8093 * Reorganized the USERS command and command reply in client library
8094 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8095 When the command is given by user we register a pending command
8096 callback that will reprocess the command after the reply has been
8097 received from the server. When reprocessing the packet we then
8098 display the information. Thus, the USERS information is displayed
8099 now in the command callback instead of in the command reply
8100 callback. The processing of the command is same as previously
8101 when server has sent the command reply in the JOINing process.
8103 * Added to USERS command in silcd/command_reply.c to join the client,
8104 we didn't use to know about, to the channel after we've created
8105 a client entry for it. Also, for clienet we did know already still
8106 check whether it is on the channel or not and add it if not.
8108 * Removed silc_server_command_join_notify as the function and its
8111 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8113 * Changed the client's pending command handling to the same as the
8114 server's pending command handling. It is also now possible to
8115 execute command reply functions from other command reply
8116 function as the function callbacks for commands and command
8117 replies are one and same. The pending commands are not static
8118 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8119 in client connection context. Thus, pending commands are server
8120 connection specific as it is convenient.
8122 Changed the function silc_client_command_pending and
8123 silc_client_command_pending_del and added new function
8124 silc_client_command_pending_check. Removed the
8125 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8128 * Added cmd_ident, current command identifier, to the client
8129 connection context in lib/silcclient/client.h to keep track on
8130 command identifiers used in command sending. Client's command reply
8131 function handling now supports the mandatory command identifiers.
8133 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8134 funtions in client to fully support pending command callbacks.
8136 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8137 as one of the arguments to the application in the command reply
8140 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8141 before first releasing SILC but came back. Now it is removed again
8142 and should come back nomore. The FORWARDED flag was used only
8143 by the JOINing procedure by forwarding the command packet to router.
8144 Now, the JOINing procedure has been changed to more generic (due
8145 to various router environment issues) and FORWARDED is not needed
8146 anymore for anything. The protocol specification is yet to be
8149 Now, removed silc_server_packet_forward from server and the flag
8150 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8152 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8154 * Renamed NAMES command to USERS command. The NAMES was named that
8155 due to historical reasons. Now it is renamed. Also, rewrote
8156 parts of the USERS command. The nickname list is not sent anymore
8157 by the server. Only Client ID and mode lists are sent in the USERS
8158 command. Changed this also to the protocol specification.
8160 The client now resolves the names and stuff after it receives
8161 the USERS list from the server when joining to the channel.
8163 * WHOIS and IDENTIFY commands has been changed to support multiple
8164 Client ID's per command. One can now search for multiple users
8165 in the network by sending only one WHOIS or IDENTIFY command.
8166 Changed the code and the protocol specifications.
8168 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8169 uses silc_server_command_whois_parse to parse the request. */
8171 * If normal server, do not parse the WHOIS and IDENTIFY requests
8172 before sending it to the router. Saves some time.
8174 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8176 * Fixed JOIN command on client library. Wrong number of arguments
8177 used to crash the client.
8179 * Added silc_server_channel_has_global function to check whether
8180 channel has global users or not.
8182 * Added silc_server_channel_has_local function to check whether channel
8183 has locally connected clients on the channel.
8185 * The silc_server_remove_from_one_channel now checks whether the
8186 channel has global users or not after given client was removed from
8187 the channel. It also checks whether the channel has local clients
8188 on the channel anymore. If it does not have then the channel entry
8189 is removed as it is not needed anymore.
8191 * The silc_server_notify now checks on JOIN notify whether the joining
8192 client is one of locally connected or global. If it is global then
8193 the channel has now global users on the channel and that is marked
8194 to the channel entry. Also, it now saves the global client to
8195 global list who is joining and JOINs it to the channel. This is
8196 for normal server, that is.
8198 Changed silc_server_send_notify_on_channel,
8199 silc_server_packet_relay_to_channel and
8200 silc_server_packet_send_to_channel check if we are normal server
8201 and client has router set (ie. global client) do not send the
8202 message to that client, as it is already routed to our router.
8204 * Implemented LEAVE notify type handling in silc_server_notify
8207 * Tested LEAVE command in router environment successfully. Tested
8208 with two routers, two servers and two clients.
8212 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8214 * Implemented SIGNOFF notify type handling in silc_server_notify
8217 * silc_server_remove_id now removes the client entry from all channels
8218 it has joined and thusly sends SIGNOFF notify type.
8220 * Rewrote the NAMES list generation in server by removing two excess
8221 loops. The lists are created now inside one loop.
8223 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8225 * silc_server_remove_channel_user checks now also global list
8226 for channel and client.
8228 * silc_server_new_channel_user checks now both local and global
8229 list for channel and client. Fixed a bug in client id decoding.
8230 Used to decode wrong buffer.
8232 * silc_server_channel_message checks now both local and global
8233 list for channel entry.
8235 * Tested channel joining (hence JOIN) in router environment
8236 successfully. Tested with two routers, two servers and two
8239 * Tested channel message sending in router environment successfully.
8241 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8243 * Added silc_server_save_channel_key into server.[ch] to save the
8244 received channel key in Channel Key payload processing. It is
8245 also used in JOIN command reply handling.
8247 Equivalent function silc_client_save_channel_key added into
8248 client.[ch] into client library.
8250 * Changed JOIN command reply to send information whether the channel
8251 was created or not (is existing already) and the channel key
8252 payload. Changed protocol specs accordingly.
8254 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8255 the request was sent by ID and not by nickname. Crashed on
8258 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8260 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8261 now correctly save the received data.
8263 * silc_server_free_sock_user_data now notifies routers in the
8264 network about entities leaving the network.
8266 At the same time implemented functions silc_server_remove_id
8267 and silc_server_send_remove_id to receive and send REMOVE_ID
8268 packets. The packet is used to notify routers in the network
8269 about leaving entities. The ID removed will become invalid in
8272 * Added function silc_idlist_del_server into server. Removes and
8273 free's server entry from ID list.
8275 * silc_server_private_message function now checks, if we are router,
8276 that the destination ID really is valid ID, naturally.
8278 * In router when NEW_ID packet is received (for new client) the
8279 hash of the Client ID is saved in the ID Cache but the
8280 client->nickname is set to NULL, instead of putting the hash
8283 IDENTIFY command now also checks that client->nickname must be
8284 valid. If it is not if will request the data from the server who
8285 owns the client. Added new function
8286 silc_server_command_identify_check.
8288 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8289 to set the command to already allocated Command Payload.
8291 * Tested private message sending in router environment with two
8292 routers, two servers and two clients. Fixed minor bugs and now
8295 * Fixed segfault from client's NAMES command. Used to crash if
8298 * Forwarded packets must not be routed even if it is not destined
8299 to the receiver. Changed server code comply with this.
8301 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8303 * Added `require_reverse_mapping' boolean value to ServerParams
8304 structure. If TRUE (not default) the server will require that
8305 the connecting host has fully qualified domain name.
8307 If the reverse mapping is not required and hostname could not be
8308 found the IP address is used as hostname.
8310 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8312 * Implemented version string checking to both client and server.
8313 The check is incomplete currently due to the abnormal version
8314 strings used in development version of SILC.
8316 * Changed all command functions in server to use the new
8319 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8321 * Changed char *data to unsigned char *data in ID Cache system to
8322 support binary data as ID Cache data. Changed code to support
8323 binary data in lib/silccore/idcache.c.
8325 * Renamed silc_server_packet_relay_command_reply to
8326 silc_server_command_reply as it is normal packet receiving
8327 function. Rewrote the function to accept command replys for
8328 servers and not only for clients.
8330 * Mark remote router always as registered server if we are connecting
8331 to it. Otherwise, commands sent by the router to us are ignored.
8333 * All ID List find routines now returns the ID Cache Entry pointer
8334 as well if requested.
8336 * WHOIS command works now in router environment, tested with two
8337 routers, two servers and two clients.
8339 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8340 in router environment (as it is almost equivalent to WHOIS) but
8341 hasn't been tested thoroughly. Added new functions:
8343 silc_server_command_identify_parse
8344 silc_server_command_identify_send_reply
8345 silc_server_command_identify_from_client
8346 silc_server_command_identify_from_server
8348 * Disabled route cache adding because adding two different ID's with
8349 same IP replaces the old cache entry thus giving wrong route.
8350 The entry->router->connection is always the fastest route anyway
8351 so route cache may not be needed. Of course, new routes maybe
8352 established after receiving the ID when the entry->router->connection
8353 might not be anymore the most optimal.
8355 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8357 * Add route cache for received ID for fast routing.
8359 * Added silc_server_packet_route to route received packet on router
8360 that is not destined to us.
8362 * Renamed silc_server_get_route to silc_server_route_get.
8364 * Added id_string and id_string_len fields into SilcServer to
8365 include encoded ServerID for fast comparing without excess
8366 encoding of the ID's.
8368 * Cleaned up WHOIS command on server side. Added following static
8371 silc_server_command_whois_parse
8372 silc_server_command_whois_check
8373 silc_server_command_whois_send_reply
8374 silc_server_command_whois_from_client
8375 silc_server_command_whois_from_server
8377 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8378 arguments in command replies. All command functions should be
8379 updated to use this macro.
8381 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8383 * Minor typo fixes on command reply handling on server.
8385 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8387 * Added silc_server_command_add_to_channel internal routine to add
8388 the client to the channel after router has created the channel and
8389 sent command reply to the server.
8391 * Added generic silc_server_send_command to send any command from
8394 * Use static buffer with ID rendering instead of duplicating data.
8396 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8398 * Fixed a channel user mode bug when joining to a channel server gave
8399 everybody channel founder rights, oops.
8401 * We mark ourselves as the router of the incoming server connection
8402 if we are router ourselves. This way we can check in some packet
8403 sending functions whether it is locally connected server. For
8404 incoming router connections we put NULL.
8406 * For router sending packets locally means now always sending the
8407 packet cell wide; to local clients and local servers. For normal
8408 server sending packet locally means sending it to only local
8411 * Fixed the JOIN command to really work in router environment. If the
8412 channel is created it is always created by the router. Router is
8413 also responsible of making the initial joining to the channel,
8414 sending JOIN notify to the sending server and distributing
8415 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8416 does not exist server doesn't do anything else but forward the
8417 command to the router which performs everything.
8419 * Added silc_server_send_channel_key function to send the Channel Key
8422 * Added silc_server_create_channel_key to create new channel key. The
8423 channel key is now re-generated everytime someone joins or leaves
8424 a channel, as protocol dictates. Note: channel->key_len is the
8427 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8429 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8430 packet_receive.[ch] to separate packet sending and receiving
8431 routines. The server.[ch] now includes everything else including
8432 actual packet processing (writing and reading data) and other
8435 Renamed silc_server_private_message_send_internal to
8436 silc_server_send_private_message. The routine is still though
8437 used only to relay private messages as server does not send
8438 private messages itself.
8440 Renamed silc_server_new_channel to silc_server_create_new_channel
8441 and added new function sicl_server_new_channel that handles the
8442 incoming New Channel packet. Added also new sending function
8443 silc_server_send_new_channel to send New Channel Payload.
8445 * Added new function silc_server_notify to process incoming notify
8446 packet to the server/router. Server may then relay the notify
8447 to clients if needed.
8449 * Added new function silc_server_new_channel_user to process incoming
8450 New Channel User packet. Router will redistribute the packet and
8451 send JOIN notify to its local clients and locally connected servers
8452 if needed. Normal server will send JOIN notify to its local client
8453 on same channel when received this packet. Added also corresponding
8454 sending function silc_server_send_new_channel_user to sent the
8457 * Added boolean route argument to send_notif_to_channel and
8458 packet_send_to_channel functions to attempt to route the packet
8459 if it is TRUE and send only locally if it is FALSE.
8461 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8463 * silc_server_replace_id now broadcasts the received replace ID
8464 packet if it is not broadcast packet already. The router must
8465 broadcast to inform other routers about changed ID.
8467 * Added backpointer to server's router into SilcServer context in
8468 silcd/server_internal.h.
8470 * Fixed silc_server_packet_broadcast to send correct broadcast
8473 * The channel key is now distributed to the local client as soon
8474 as it is received from the router (in router environment) so that
8475 no other packet may be sent for the channel until client has
8478 * silc_server_remove_channel_user now broadcasts the received
8479 Remove Channel User packet if it is not broadcast packet already.
8480 The router must broadcast to inform other routers about removed
8483 * Added users field into SilcPacketContext that is a reference count
8484 of the context. One can increase the reference count by calling
8485 silc_packet_context_dup which is now changed to just increase the
8486 reference count instead of duplicating the data. The reference
8487 count is decresed by calling silc_packet_context_free that will
8488 free the data after the reference count hits zero.
8490 For now on the packet context and everything allocated into it
8491 (including the raw packet from network) must be freed by calling
8492 the new silc_packet_context_free function. Added also new function
8493 silc_packet_context_alloc that must be used now to allocate the
8494 context. This also means that if a routine is asynchronous from
8495 silc_[client/server]_packet_parse_type the packet context must
8496 be duplicated by calling silc_packet_context_dup. Otherwise it
8497 gets free'd after silc_[client/server]_packet_parse_type returns.
8498 Also, one must remember that if packet is duplicated then its
8499 reference count must be decresed by calling the free function as
8500 many times as it was duplicated.
8502 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8503 from both client and server.
8505 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8507 * Made joining to a channel working in router environment.
8509 * Cleaned up JOIN command on server side and create function
8510 silc_server_command_join_channel internal routine to make the
8513 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8515 * Changed silc_command_pending list to SilcDList. Also, added
8516 `ident' field to SilcServerCommandPending structure to identify
8517 the reply and to call correct callback.
8519 Added silc_server_command_pending_check function to replace the
8520 corresnponding macro. The silc_command_pending list is not
8523 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8524 to set identifier to previously allocated Command Payload. It
8525 is used to set identifier for command when resending Command
8528 * Added silc_command_payload_encode_payload to encode Command
8529 Payload buffer from SilcCommandPayload structure.
8531 * Added silc_argument_payload_encode_payload to encode Argument
8532 payload buffer from SilcArgumentPayload structure.
8534 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8536 * Changed WHOIS command to support router connection on server side.
8537 The whois request is always sent to router unless the server is
8538 standalone server. After server has received the reply from the
8539 router will it send the reply to the client.
8541 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8542 broadcast received broadcast packet. The function is used only
8543 by router. The broadcast packet is always sent to the router's
8546 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8547 render given ID to printable string, for log files for example.
8549 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8551 * Made basic router to router connections working. At least they
8552 can now connect to each other but nothing really works the way
8553 they are supposed - yet.
8555 * Added new initiator token to RouterConnection configuration
8556 file in silcd/serverconfig.[ch]. It is used to tell whether we
8557 are the initiator to the remote router or whether we'll expect
8558 the other end to connect.
8560 * Moved registering of listener task to silc_server_init, hence
8561 the server starts listenning as soon as it is run, even if it
8562 does not have connections to other routers. Let's see how well
8565 * Changed default connection retry timeouts for more suitable in
8568 * Removed cipher and such arguments from silc_idlist_add_client
8569 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8570 Added new function silc_idlist_add_data to add the keys and stuff
8573 * Added SilcIDListData structure and added it to SilcClientEntry
8574 and SilcServerEntry as their first field in the structure. This
8575 way we can explicitly cast the ID entries to the SilcIDListData
8576 structure and get common data for the entries. In past, we had
8577 to first check what type of connection it is and then cast it to
8578 correct ID entry type. Now, we can directly cast the opaque
8579 pointer to the SilcIDListData (no matter what ID entry it actually
8580 is) and get the data needed.
8582 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8584 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8585 in some circumstances even if threre were timeout tasks, though not
8586 IO tasks, but tasks anyway. Now fixed.
8588 * Defined SilcServerConnection structure to hold connection specific
8589 stuff about directly connected servers and routers. The definition
8590 is currently in silcd/server_internal.h. I thought about having
8591 a bit more important role fro this struct but for now it is used
8592 only when connecting to other server (or router actually).
8594 * Added connecting retry support in server when connecting to
8595 router(s). The retry feature implement exponential backoff
8596 algorithm. Also, added SilcServerParams structure to hold default
8597 parameters for server. For now, it include these retry settings
8598 and are hard coded. After server is moded to be as Silc Server
8599 Library this structure will be more important.
8601 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8603 * Changed client librarys channel->clients table to SilcList and
8604 changed code accordingly.
8606 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8608 * Changed client's channel table to SilcList and changed code
8609 accordingly. Also changed SilcChannelClientEntry to include back-
8610 pointer to the channel so that client entry can use that structure
8611 as list as well and we have fast cross-reference to the channel.
8612 This change dramatically decreased the complexity of channel
8613 handling with client entry and vice versa (removed one extra
8614 loop when searching for channel entry from many functions).
8616 * Changed server->sim from table to SilcDList and changed code
8619 * NAMES command can now be used from user interface. It will show
8620 the user list on the channel, neatly.
8622 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8623 Code now saves realname of the user if it becomes available.
8625 * Renamed configure.in to configure.in.pre and made ./prepare
8626 script to automatically add correct version string to
8627 configure.in which it creates from configure.in.pre.
8629 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8631 * NAMES command reply now shows users mode with the nickname when
8634 * Moved silc_client_ch[u]mode[_char] functions from
8635 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8636 place sucks, they are utility functions and should be in some
8639 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8641 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8644 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8648 * Added TRQ (efficient deque and list library) into lib/trq. This is
8649 a very good list library that is currently used in the SILC. Defined
8650 SilcList API over the library because I didn't like the API very
8651 much. See lib/trq/silclist.h for the API and examples of how to
8652 use the API. Fixed various places in the code to use the new
8653 SilcList API. The SilcList is meant for lists that has a structure
8654 already defined as a list. It is not suitable to add just some
8655 context to the list (in TRQ, the context is the list actually).
8657 So, I defined SilcDList that can be used for the purpose where
8658 predefined list structure does not exit. This can be used as
8659 such list. Now some context just can be added to the SilcDList.
8660 Currently this list is not used in the SILC just yet, though there
8661 are a lot places where this can replace dynamically allocated
8662 tables and I will fix these places, later, to use SilcDList.
8663 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8664 and use TRQ internally).
8666 Also fixed some annoying warning messages that the original TRQ
8667 code generated. Also minor changes to TRQ's Makefile.in.
8669 * Added support for querying by Client ID to both WHOIS and
8670 IDENTIFY commands into server, as required by the protocol.
8672 * Removed method function pointers from SilcBuffer structure. They
8673 weren't used to anything and just increased the context size for
8674 no good reason. This change also made silc_buffer_alloc and
8675 silc_buffer_free functions inline functions.
8677 * Disabled command flooding detection support until it's fixed so
8678 that it accepts commands in but does not execute them more than once
8681 * Added silc_net_localhost(), to return local hostname, into
8682 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8683 that must be initialized before calling silc_client_init.
8685 * Added new function: silc_server_send_notify_on_channels to send
8686 notify messages to all channels client has joined. It is assured
8687 that the message is sent only once per client.
8689 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8690 lib/silcutil/silcutil.[ch] as silc_format function. The new
8691 function is generic and is used by server as well, not only by
8692 the logging routines.
8694 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8695 the provided version string was not acceptable. Added new function:
8696 silc_ske_check_version into lib/silcske/silcske.h. The function
8697 must be implemented by the application (client or server) and it
8698 does not reside in the SKE library. The function checks the version
8699 string remote end sent.
8701 * Added back pointers (to opaque context and to SilcSocketConnection)
8702 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8704 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8705 duplicate packet context structure.
8707 * Changed `notify' client operation to send same arguments as client
8708 receives from server except for ID's. ID's are mapped to correct
8709 ID entry and that is returned. Also, if channel entry is not sent
8710 by server but the notify is for channel the channel entry is sent
8711 to application (otherwise application doesn't know that it is for
8712 channel (library gets it from packet's Destination ID)).
8714 * Added silc_client_remove_from_channels into client library to
8715 remove a client from all channels it has joined to. Used when
8716 received SIGNOFF notify from server. Added also new function
8717 silc_client_replace_from_channels to replace old ID entry with
8718 new ID entry on all channels. Used when received NICK_CHANGE
8721 * Fixed ID Cache list handling in silc_idlist_get_client in
8722 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8723 to get (or query) client by ID.
8725 * Updated TODO list.
8727 * Added connection authentication status message defined by the
8728 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8729 support for these into the code in client and server side.
8731 * Added generic function silc_client_send_command to send any command
8732 with variable argument list. Application should use this function
8733 to send commands if the command functions provided by the library
8734 does not suite for the application's user interface needs.
8736 * Added new `failure' client operation. Application is notified about
8737 received failure packet if client is executing a protocol. In this
8738 case the protocol's execution has failed.
8740 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8741 is required by the protocol.
8743 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8744 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8747 * Added status flag to SilcSKE object to indicate realtime status
8748 of the SKE protocol.
8750 * Application receives now exactly same command reply arguments as
8751 the library receives from server. However, if ID is received the
8752 corresponding ID entry is returned to the application (eg. Client
8753 ID is mapped to correct SilcClientEntry entry and that is returned).
8754 Changed command_reply client operation due to this change.
8756 * Changed all ID's in commands and in command replys as ID Payloads.
8757 Change affected both client and server side codes.
8759 All ID's sent in SILC network (with execption of ID's in SILC
8760 Packet header) are sent in ID Payload to support variable length
8763 * Server now notifies nick changes and notifies all clients on
8764 the channels about the new nickname (about the new Client ID,
8767 * Implemented CMODE command to change channel modes. Supports all
8768 channel modes defined by the protocol specs except ban and invite
8769 lists. (Also, private channel key mode is supported but support for
8770 setting private channel key in client is missing, thus, this mode
8771 has no effect on client side (except that server requires that the
8772 client uses private channel key and normal channel traffic does not
8775 Also, invite mode works per se, but INVITE command does not work
8776 yet correctly, so you can set channel as invite only channel but
8777 inviting clients to the channel does not work (it is yet to be
8778 thought what's the best way to do it).
8780 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8781 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8782 Implemented CUMODE command to change user's mode on the channel.
8783 Supports all modes defined by the protocol specs.
8785 * Added NAMES command reply to return users modes on the channel.
8787 * Removed unnecessary and slow ciphers from lib/silccrypt.
8789 * Set SO_KEEPALIVE option to connection sockets by default.
8791 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8793 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8794 redefined the Notify Payload into protocol specs.
8796 * Added silc_id_payload_parse_id to get ID directly from raw
8799 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8801 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8802 accept searching by Client ID as well.
8804 * Added support for LEAVE and SIGNOFF notify types in client library.
8806 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8807 to parse ID Payload from raw data.
8809 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8811 * Added flags parameter into silc_ske_assemble_security_properties
8812 function in lib/silcske/silcske.[ch].
8814 * Changed notify client operation to fit better for notify messages
8815 sent by server. The notify payload received from server is now
8816 passed to the application (after parsing it to SilcNotifyPayload).
8817 It is application's responsibility to retrieve the arguments
8818 from the payload and show the message the way it wants. The message
8819 sent by server is implementation specific.
8821 * Changed public keys to comply with the protocol specification.
8822 Old public keys are not supported anymore and are not compatible.
8824 * Removed nickname from Channel Payload as the latest draft removed
8825 it. The client must resolve the nickname from the NAMES command
8826 reply received when it joined the channel.
8828 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8830 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8832 * Fixed some errors in protocol specification drafts.
8834 * Created lib/silccore/silcnotify.c to implement Notify Payload
8835 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8836 generic payloads described by protocol specifications. The file
8837 includes implementations for ID Payload and Argument Payload.
8839 * Changed Command Payload implementation to use the new Argument
8840 Payload. Changed command_xxxx_payload to command_payload_xxxx
8841 to comply with SILC coding conventions.
8843 * Added suppport for Argument Payload handling in Notify Payload
8844 implementation as protocol requires it. Added the new support
8845 into server and client lib as well.
8847 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8849 * Added support for multiple nicknames on same channel. [n] is
8850 added locally to the nickname if there are more than one same
8851 nicknames on the channel.
8853 * Server now sends all nicknames that matched WHOIS request.
8854 Client also shows the list received from server.
8856 * Added TOPIC command to client side. User can now set and show
8857 current topic on channel.
8859 * Added MOTD command to client and server. Also, server sends the
8860 motd when client connects to the server.
8862 * Changed version strings to comply ISO 8601.
8864 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8866 * Fixed protocol error handling in client library. It should now
8867 cope even if the SKE fails for some reason.
8869 * Made new protocol specification drafts for submitting to IETF.
8871 * Implemented TOPIC command to server in silcd/command.c.
8873 * Added two new notify types into lib/silccore/silcnotify.h:
8874 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8875 notify nickname change and topic setting/change on a channel.
8877 * API change of command_reply operation in client library. The
8878 application gets now the status type received from server as well.
8880 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8882 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8884 * Cras fixed and optimized the packet handling even further and
8885 it should work now. Minor change to the prototype of function
8886 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8888 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8890 * Added new function into lib/silcutil/silcschedule.[ch]:
8891 silc_schedule_with_fd to select() a specified fd. The function
8892 returns after timeout expires or data arrives or goes. The
8893 function is used by packet routines to wait that all data is
8894 received from network.
8896 * Fixed data reading from network in lib/silccore/silcpacket.c.
8897 The code now assures that all data is read from the fd and then
8898 continues packet processing. This was a bug fix since the code
8899 used to drop some data in some circumstances.
8901 * Added new function into lib/silcclient/client.[ch]:
8902 silc_client_start_key_exchange to start key exchange after
8903 connection has been established to server. The code internally
8904 now uses this funtion but its main purpose was to provide it
8905 for applications that perform their own connecting. After
8906 application has created a connection it merely calls this
8907 function to start the key exchange between client and server.
8908 The library takes care of everything else after that.
8910 Updated also lib/silcclient/README to explain the usage of
8913 * Do not send to application information that connection has
8914 been established. Application gets notified it by connect
8917 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8919 * Applied cras's patch to add silc_schedule_one function. The
8920 function runs scheduler once and returns.
8922 * Fixed the scheduler after cras messed it up. The timeout
8923 handling works now as it's supposed to work.
8925 * Added into lib/silccore/ silcnotify.h to include notify
8926 message types support. Changed silc_server_send_notify*
8927 functions, in server.[ch], to support those new notify types.
8928 Added the support for the notify types into client library,
8929 as well. Added new notify client operation into ops.h in
8932 * Changed silc_server_packet_send_to_channel to send normal
8933 packets instead of just channel message packets. The function
8934 is now used to send the notify packets to channels. It is not
8935 used to send channel message packets anymore, as server never
8938 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8939 va_arg()s as it seems to require it nowadays. I guess, if SILC
8940 is compiled with older va_arg() the new code should work anyway.
8942 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8944 * Splitted core library. Core library (lib/silccore) includes
8945 now only SILC protocol specific core (and common) components.
8946 Created new utility library (lib/silcutil) that includes more
8947 generic purpose stuff. The stuff for util library was taken
8948 from the old core library. This was minor and easy split.
8950 * Created SILC Client Library (lib/silcclient) that includes
8951 implementation of the SILC client without user interface. This
8952 was major move from silc/ directory. The code has been changed
8953 so that it is transparent towards the user interface. The
8954 silc/ directory includes now the same user interface as before
8955 and it uses the new client library. Read lib/silcclient/README.
8956 Basicly, the client library performs everything else related
8957 to SILC except user interface handling. Also, configuration
8958 files are considered to be part of user interface and library
8959 does not handle them.
8961 This change also changed a lot of structures, function naming etc.
8962 Most important change was that SilcClientWindow object was
8963 renamed to SilcClientConnection in the client library. Created
8964 also new file lib/silcclient/ops.h. Also added new files
8965 silc/local_command.[ch] and silc/client_ops.[ch].
8967 All these changes were made to make it easier for user interface
8968 designers to create what ever user interface for the SILC client
8971 It is also expected that the server will be moved to lib
8972 directory as well and SILC Server Library will be created;
8973 sometimes in the future.
8975 * Removed Local commands from lib/silccore/silccommand.h as
8976 they are application specific and new client library does not
8977 handle any of those anymore.
8979 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8980 old client implementation in silc/.
8982 * Added support for callback functions in SILC_LOG_* macros.
8983 Application can now set its own callbacks that will be called
8984 instead of using the default functions that will always print
8985 the debug messages to stderr (or stdout). Also, debugging can
8986 now be disabled by setting silc_debug to FALSE and re-enabled by
8987 setting it to TRUE. Note, that logging will still work even
8988 if debugging is disabled.
8990 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8991 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8992 silc_log_reset_debug_callbacks.
8994 * To enable debugging in silc client one must give now -d
8995 option on command line.
8997 * Changed silc_schedule_init to automatically allocate task queues
8998 if they are not allocated before calling it.
9000 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9002 * Added GMP 3.1 into math library.
9004 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9006 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9007 a channel in SILC network. The packet is used by servers and
9008 routers to notify other routers that user has left a channel.
9009 This little feature was missing until now. Added the feature
9010 to protocol specification as well.
9012 Added functions: silc_server_send_remove_channel_user and
9013 silc_server_remove_channel_user into server.[ch].
9015 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9016 lib/silccore/silcpacket.h. However, they are not implemented
9019 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9021 * Fixed joining to a channel and sending channel messages
9022 between server and router. The channel message sending should
9023 now work inside a cell.
9025 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9027 * Fixed the private message sending between server and router.
9028 The private message sending should now work inside a cell.
9030 * Added silc_server_replace_id into server.[ch] to replace
9031 existing ID in the SILC network.
9033 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9034 and silc_idlist_replace_server_id into idlist.[ch] in server.
9036 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9038 * Fixed the server to server connections. Server can again now
9039 connect to router. Router to router connections probably does
9042 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9044 * Added dynamic protocol registering support. Now protocols can
9045 registered and unregistered on the fly. Patch by cras.
9047 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9049 * Added lib/contrib directory to hold routines that some platforms
9050 don't have but are needed by SILC.
9052 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9053 into lin/contrib to provide getopt() and getopt_long() for
9054 those who don't have it.
9056 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9058 * Added AWAY command to client. When away message is set and
9059 client receives a private message packet the client automatically
9060 replies to the sender with the away message.
9062 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9063 bug seemed to be the cause of recent problems when compiling
9066 * Added version detection support to SKE protocol specification
9067 and added the new changes to the SKE implementation as well.
9068 There were other minor changes in the SKE protocol as well.
9070 Many changes in lib/silcske/silcske.[ch] and in
9071 lib/silcske/payload.[ch].
9073 * Added ^U functionality, clear input line. Patch from cras.
9075 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9077 * Mainly small bugfixes on core library. Fixed some debugging
9078 logging and buffer overflow in silclog.c.
9080 * Updated config.sub and config.guess on the distribution tree.
9082 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9084 * Added command lagging support in server. Client may execute
9085 commands now only once in two seconds.
9087 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9089 * Optimized packet reception. MAC computation and checking is now
9090 also more optimized. A lot previously duplicated code is now
9091 used as generic by both client and server.
9093 * Fixed key pair generation in clientutil.c
9095 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9097 * Added into lib/silccore/silcbufutil.[ch] new function;
9098 silc_buffer_realloc.
9100 * Moved generic packet sending/encryption functions to
9101 lib/silccore/silcpacket.[ch] from client and server. Some
9102 rewriting of the functions.
9104 * Moved all generic packet reception/decryption functions to
9105 lib/silccore/silcpacket.[ch] from client and server. The
9106 packet processing is now much cleaner in both client and server.
9107 These were major changes in both client and server.
9109 * Created many common functions in server to do packet sending.
9110 Previously code were duplicated a lot, this has been removed
9113 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9115 * Rewrote major parts of the ID cache system. Don't know
9116 whether it is better now or not but at least the API is more
9119 * Major rewrite on ID cache stuff on client because of the ID
9120 cache API changes. Added idlist.c to client.
9122 * Also major rewrite on ID cache stuff on server as well.
9123 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9124 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9125 in hand, instead they are all put into the ID cache system now.
9126 All server_idlist_* routines uses ID cache now instead of
9127 traversing its own lists (those lists does not exist anymore).
9128 SilcIDList though still exists. Also, SilcXXXEntry's are
9131 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9133 * Finally made the SKE implementation compliant to the protocol
9134 specification. All mp integers are now binary encoded as
9135 opposed being HEX encoded.
9137 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9140 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9141 functions: silc_[encode/decode]_pem. Also added function
9142 silc_encode_pem_file to PEM encode with newlines ('\n') for
9145 * SILC public keys are now encoded either PEM or binary. Same
9146 option is for private keys as well. By default private keys
9147 are binary encoded and public keys PEM encoded. Silly HEX
9148 encoding were removed.
9150 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9151 function to create fingerprints.
9153 * Fixed a bug in SHA1; does not change the original data anymore.
9155 * Partly implemented INFO command on client and server side.
9156 Fixed CLEAR command. Changes to SERVER command; show current
9157 server(s) when giving command without arguments. Added
9158 VERSION command to client.
9160 * Added check to server that unregistered connections cannot
9161 execute commands (unless it is specificly allowed).
9163 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9165 * Fixed screen refresh.
9167 * Fixed channel joining bug from client. On some circumstances
9168 client tried to join to a channel it had already joined.
9170 * Added public key verification process into client's protocol.c.
9171 The client now verifies the public key from user and saves
9172 it into ~./silc/serverkeys/ directory.
9174 Added into: clientutil.[ch]: silc_client_verify_server_key.
9176 * Changed SKE protocol's silc_ske_initiator_finish function
9177 to accept callback function that verifies the received public
9178 key. Removed old silc_ske_verify_public_key function.
9180 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9182 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9183 silc_pkcs_private_key[_data]_set.
9185 * Made the password and public authentication more cleaner in
9186 server's protocol.c.
9188 * Removed historic and obsolete protocol `channel_auth' from
9189 both client and server.
9191 * Removed wrong way of sending command status messages from
9192 server to client in server's command.c. The old way violated
9193 protocol specification.
9195 Changes to silccore/silccommand.[ch]: removed
9196 silc_command_encode_status_payload -> not needed anymore,
9197 changed silc_command_encode_payload_va to accept extra
9198 argument on variable argument list. The argument type must
9199 now be provided to the function. Also, added new function:
9200 silc_command_encode_reply_payload_va which is same as
9201 normal command_encode_payload_va except command status type
9202 is provided as extra argument.
9204 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9206 * Added ~./silc directory handling. The directory includes the
9207 public and private keys for the client.
9209 Added silc_client_check_silc_dir, silc_client_create_identifier
9210 and silc_client_load_keys.
9212 * Implemented SILC protocol compliant public key. Added public
9213 and private key saving to and loading from files.
9215 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9216 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9217 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9218 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9219 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9221 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9222 silc_pkcs_load_[public/private]_key.
9224 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9226 * Added silc_server_get_route (route.[ch]) to get connection
9227 data for the fastest route for given ID.
9229 * Implemented INVITE command on client and server. The command
9230 were re-defined in the SILC Protocol Specification and the
9231 implementation now complies with the specification.
9233 * Implemented PING command on client and server.
9235 * Implemented NAMES command on client and server. The server side
9236 supports currently only normal server not router server yet.
9237 Some changes to NAMES definition in SILC protocol specification.
9239 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9241 * Implemented LEAVE command on client and server.
9243 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9244 again. This change was made to the protocol as well. Server
9245 should not violate the protocol specification anymore.
9247 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9249 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9250 was tested. SOCKS4 was not but should work anyway.
