1 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * In JOIN notify handling, mark that the cache entry of the
4 client cannot be expired. Can cause crashes on normal
5 server (asserts client->channels). Affected file is
6 silcd/packet_receive.c.
8 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
10 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
11 for implied search (not needed on platforms which has native
12 pthreads library). Use --without-pthreads to disable threads.
13 Affected file is configure.in.pre
15 * Fixed --with-iconv on platforms which need to bypass (broken)
16 native iconv(). Affected file is configure.in.pre
18 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
20 * Moved -C option parsing in Irssi SILC client at same time
21 as other options. The UI was initialized earlier and caused
22 problems on command line. Bug #16. Affected file is
23 irssi/src/silc/core/silc-core.c.
25 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
27 * Added global variable silc_log_timestamp that tells silclog
28 wether to print or not the timestamp in the logging files.
29 Affected file lib/silcutil/silclog.[ch].
31 * Added silcd configuration option Timestamp in the Logging
32 section. Affected file silcd/serverconfig.[ch],
33 doc/example_silcd.conf.in.
35 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
37 * Fixed fingerprint checking to check for entirely empty
38 fingerprint instead of two first bytes when determining
39 if it is set. Bug #18. Affected file silcd/command.c.
41 * Fixed duplicate PKCS name registering to not allow it.
42 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
44 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
46 * Conditionalize non-gcc compiler optimizations for various
47 platforms, enable those commented out. Cleanups.
48 Affected file lib/silcmath/mpi/configure.in
50 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
52 * silc_rng_exec_command() left zombie processes if command
53 didn't generate any output. Affected file
54 lib/silccrypt/silcrng.c
56 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
58 * Rewrote iconv checking, introduce --with-iconv for systems
59 which rely on libiconv. Check if iconv() provided by libc
60 is good enough, otherwise demand libiconv. Affected file
63 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
65 * Search for ldopen() also in libc. This enables SIM support
66 on *BSD systems. Based on patch from Alex Zepeda. Affected
69 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
71 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
72 This fixes prepare on *BSD systems. Affected file
75 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
77 * More fixed for not having purge timeout for global clients
78 that are on channel. Affected files silcd/command_reply.c
81 * Fixed the rekey protocol to work with backup router connections.
82 Rekey packets are now allowed on disabled connections as
83 well. Affected files silcd/packet_send.c and server.c.
85 * Do not switch to be as backup router when shutting down and
86 closing the primary connection. Affected file silcd/server.c.
88 * Fixed memory leaks in backup router deleting. Added
89 silc_server_backup_free to free all data during shutdown of
90 server. Affected files silcd/server_backup.[ch].
92 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Do not process commands if the sock->user_data is NULL.
95 Affected file silcd/command.c.
97 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Fixed buffer overflow and security problems (loosing bits
100 in CFB encryption) in SILC RNG. Problems reported by
101 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
103 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Added yet more checks that client is not expired on global
106 list if it is on channels. Affected file is
107 silcd/command_reply.c.
109 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
111 * Merged c0ffee's MIME signal patch which adds support for
112 sending also MIME messages in Irssi SILC Client, and handling
113 received MIME messages in a signal (and perhaps doing something
114 to non-textual MIME messages).
116 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
118 * Fixed pending command deletion in server and client library
119 to check the whole list instead of breaking after first found.
120 The affected files are silcd/command.[ch] and
121 lib/silcclient/command.[ch].
123 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Return NO_SUCH_CHANNEL error in USERS for channel that is
126 secret or private, otherwise it's possible to find out
127 whether a secret channel exists or not. Affected file
130 * If CMODE change fails during the mode setting, assure that
131 the old mode mask is set for the channel back. Affected
132 file silcd/command.c.
134 * Fixed passphrase saving on +a channel on normal server
135 after successful JOIN command. Affected file silcd/command.c.
137 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
139 * Remove server/router operator privileges in DETACH command,
140 since it's possible to resume to server where these
141 privileges would not be allowed for the client. Affected
142 file silcd/command.c.
144 * Do not set to wait for backup in rehash of the server.
145 Affected file silcd/server.c.
147 * Do not check listener sockets when counting how many
148 socket connections we have. Affected file is
151 * Do not announce disconnected clients that are remaining
152 in history (for WHOWAS). This is because SIGNOFF notify
153 for these has been sent earlier already. Affected file
156 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
158 * Buffer overflow with CUMODE command's mode->mode character
159 conversion. Reported by Ville Räsänen. Affected file
160 lib/silcutil/silcutil.c.
162 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
164 * Allow heartbeat packets to go disabled connections anyway.
165 Affected files silcd/server.c and silcd/packet_send.c.
167 * Do not broadcast New Channel packets with List flag set
168 in the packet to backup routers. The router must check
169 for the correctness of the packets before sending them.
170 It is possible that router will have enforce Channel ID
171 change and this would cause desync in the backup router.
172 Affected file silcd/packet_receive.c.
174 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
175 are handled in list parsing. They are not list packets
176 anymore. Affected file silcd/packet_receive.c.
178 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
180 * Stop waiting for backup router through the timeout, not
181 directly after backup router has arrived. Affected file
184 * Do not re-create channel keys and send them when removing
185 clients in server shutdown. Affected files are
186 silcd/server_internal.h and silcd/server_util.c.
188 * Notify distribution to backup routers was missing from
189 the silc_server_send_notify_dest function which caused
190 desyncing problems with backup router. Affected file is
193 * The client's channel removing was working wrong on
194 backup router. It assumed that it doesn't know global
195 information but backup router does know. For this reason
196 it could remove channel when it wasn't supposed to do that.
197 Affected file silcd/server.c and silcd/server_util.c.
199 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
201 * Stop for a couple seconds after badkup router has become
202 primary router. Affected file silcd/server.c.
204 * Added silc_server_remove_servers_by_server, which is used
205 to remove servers originated from some other server. Also
206 clients of those servers can be removed too. Affected file
207 silcd/server_util.[ch].
209 * When removing clients after a server has signed of remove
210 also all servers behind that server (unless they are known
211 to be available locally), and send SERVER_SIGNOFF for each
212 of the server separately. Also the signed off clients are
213 sent now separately per signed off server. The affected files
214 are silcd/server.c and silcd/server_util.[ch].
216 * All servers added with silc_idlist_add_server must always
217 have both "router" and "connection" pointers set. Otherwise,
218 bad server entries may be left around in the cache.
219 Affected file silcd/command_reply.c.
221 * Do not create the channel key in NEW_CHANNEL packet
222 processing if the channel is empty. Affected file
223 silcd/packet_receive.c.
225 * Completed backup router support for standalone routers.
226 Supports also servers in the cell that do not use the backup
229 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
231 * Fixed a bug in silc_string_regexify which did not add '^'
232 at the start of each string, and thus the matching was
233 not explicit. For example ban list iikone@*!*@* would
234 match also "priikone", which is wrong, it would have to be
235 *iikone@*!*@* to match also "priikone". Affected
236 file lib/silcutil/unix/silcunixutil.c.
238 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
240 * Enable all local server connections before updating client
241 caches when we've become backup router. Otherwise, signoff
242 packets may not reach the clients. Affected files are
243 silcd/server.c and silcd/server_util.[ch].
245 * Fixed a bug in version string parsing which could crash
246 the program with specially formatted version string.
247 Bug reported and patch provided by Ville Räsänen. Affected
248 file lib/silcutil/silcutil.c.
250 * Handle the disconnection immediately when DISCONNECT
251 packet is received in server. Affected file silcd/server.c.
253 * Primary router now waits a short time (10 seconds) for
254 backup router connection before accepting any other
255 connection (except local). Affected file silcd/server.c,
258 * Fixed a crash in client libary in NICK_CHANGE notify when
259 NICK_CHANGE arrived for client entry we are resolving
260 currently. Affected file lib/silcclient/client_notify.c.
262 * Call the sconn->callback completion even if error had
263 occurred. Start reconnecting always if connection to
264 primary router fails during backup router protocol.
265 Affected files silcd/server.c and server_backup.c.
267 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
269 * Added functions silc_server_send_opers and
270 silc_server_send_opers_notify to send packets stricly
271 to operators. Added macro SILC_SERVER_SEND_OPERS macro
272 to send variable argument notify to operators.
273 Affected files silcd/packet_send.[ch] and silcd/server.h.
275 * Removed UMODE rights checking with UMODE_CHANGE notify.
276 Affected file silcd/packet_receive.c.
278 * Server/router operator now receives notify when network
279 switches to backup router and when it resumes the use of
280 primary router. Affected file silcd/server.c and
281 silcd/server_backup.c.
283 * Fixed the updating of client information after backup
284 resuming protocol is over; update all except local clients
285 to the new primary router. The affected file is
288 * Added support for closing active connections in rehash
289 that were unconfigured by the user. Supports currently
290 closing server and router connections. Affected file
293 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
295 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
297 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
298 is NULL since seems that on some platforms NULL is allowed
299 and on some it's not. Fallback encoding is used instead.
300 Affected file lib/silcutil/silcstrutil.c.
302 * Fixed statistics updating for incoming server connection
303 which could cause problems when re-connecting. Affected
306 * Preliminary backup router support for standalone router
307 added. Affected files in silcd/.
309 * Mark server connections in backup router disabled before
310 and after backup protocol. Affected file is
311 silcd/server_backup.c.
313 * Added support for reconnecting to remote server connection
314 even if the protocol fails, and if the configuration wants
315 us to keep trying to connect anyway.
317 Server connection is not allowed to backup router if
318 backup router does not have connection to primary router yet.
320 Affected file is silcd/server.c.
322 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Added silc_client_udpate_server function to update changed
325 server info. Affected file lib/silcclient/idlist.[ch].
327 * Added check for server entries that are being resolved when
328 notify is received. If being resolved, handle the received
329 notify only after it's resolved so that all notifys are
330 handled in same order as received from the server.
332 Added similar resolver check to channel entries. Every
333 notify that cause resolving of any information that affects
334 channel entry marks the channel entry in waiting state.
335 After whatever resolving is over the waiters are signalled
336 and only then the notifys are handled in the same order
337 as delivered from the server.
339 Affected files are lib/silcclient/idlist.[ch], and
342 * Fixed KILLED notify handling in normal server. Affected
343 file silcd/packet_receive.c.
345 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
346 is locally connected, or was locally connected (but may
347 be detached and connection is not active). Added also
348 SILC_IS_LOCAL for checking this status. Affected files
349 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
350 silcd/server.c and silcd/server_internal.h.
352 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Don't send or handle TOPIC_SET if topic is already set and
355 is same as being set. Affected files silcd/command.c and
356 silcd/packet_receive.c.
358 * Fixed CMODE change rights checking to work correctly when
359 removing modes by operator. Affected file is
362 * Fixed some handling with New Channel packet in router and
363 fixed some CMODE_CHANGE notify handling in server and router.
364 Affected file is silcd/packet_receive.c.
366 * Changed "disconnect" client operation to include the
367 reason of the disconnection and optional disconnection
368 message. Affected file lib/silcclient/silcclient.h.
370 * Made the compilation of lib/contrib/ stuff conditional.
371 Affected files configure.in.pre, lib/contrib/Makefile.am.
373 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
375 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
376 to the sender of the notify too, to avoid situation where two
377 notifys are in the network at the same time going to oppsite
378 directions. Affected file silcd/packet_receice.c.
380 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
382 * Delete the client from channel even if the cilent->id is
383 NULL. It was possible that client was deleted without
384 removing from channels (theoretically at least). Affected
385 file silcd/server.c and silcd/server_util.c.
387 * Free the client data too when resuming is not successful.
388 Affected file silcd/packet_receive.c.
390 * Merged some code from c0ffee's silc-plugin. Affected files
391 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
393 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
394 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
395 to the primary router connection, the other one returns
396 TRUE if packet must be broadcasted to network.
398 * All notifys that are destined to primary router (to network)
399 are now automatically sent to backup routers even if the
400 router is standalone (and has backup router). Affected files
403 * Added --without-irssi and --without-silcd configuration
404 options for disabling the compilation of these applications.
405 Affected file configure.in.pre and prepare.
407 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
410 UTF-8 encoding and decoding. Added also new encodings
411 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
413 Added also SILC_STRING_LANGUAGE which is language and charset
414 specific encoder and decoer for those platforms that support
415 iconv(). It can convert the UTF-8 to and from the locale
416 specific character set.
418 Affected file lib/silcutil/silcstrutil.[ch].
420 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
422 * Added function silc_get_command_name to the file
423 lib/silcutil/silcutil.[ch].
425 * Improved the server debug output a bit. Affected files are
428 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
430 * Save the channel passphrase when received succesful JOIN
431 command reply from router, on normal server. Otherwise
432 joinig +a channels from normal server is not possible.
433 Affected file silcd/command.c.
435 * Fixed a bug in TOPIC_SET notify handling. The notifier
436 may be other than client too, like server or channel.
437 It expected it to always be only client and ignored the
438 notify. Affected file silcd/packet_recieve.c.
440 * Removed some (unnecessary) debug printing from
441 lib/silccore/silcid.c and lib/silccore/silcargument.c.
443 * Do not force CMODE_CHANGE when server is announcing new
446 Router announces stuff only after server reannounces channel
447 after CHANNEL_CHANGE notify.
449 These fixes optimizes the announcing procedure, and perhaps
450 fixes some problems too. Affected file silcd/packet_receive.c.
452 * Fixed SERVER_SIGNOFF sending to local clients. It was
453 totally broken and sent the notify to all local clients,
454 instead of only to those that was on same channel as the
455 signing off clients. Affected file silcd/server_util.c.
457 * Added -D option to server. It can be used to give debug
458 level. The levels are from 0 - 99, and are predefined for
459 smooth server debugging. (see silcd.c for the predefined
460 levels). Affected file silcd/server.c.
462 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
464 * Fixed a bug in Irssi SILC client to close the connection
465 properly when disconnecting from server. Affected file
466 irssi/src/silc/core/client_ops.c.
468 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
470 * When authenticating as founder during JOIN command, check
471 that the one authenticating becomes the only founder on the
472 channel. Affected file silcd/command.c.
474 * Better checking for founder mode setting when CUMODE_CHANGE
475 notify is received. Affected file silcd/packet_receive.c.
477 * Close all connections when shutting down the server by sending
478 DISCONNECT packet. Close all listeners too when shutting
479 down the server. Affected file silcd/server.c.
481 * Handle DISCONNECT packet correctly in client library by
482 calling the "disconnect" client operation. Affected file
483 lib/silcclient/client.c.
485 * Handle local errors correctly during resuming. Affected
486 file lib/silcclient/client.c.
488 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
490 * The log file is not dupped internally anymore in
491 lib/silcutil/silclog.c. Fixed memory leaks too.
493 * The scheduler now dispatches all pending timeout tasks
494 when it is uninitialized with silc_schedule_uninit.
495 Affected file lib/silcutil/silcschedule.c.
497 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
499 * Added --enable-stack-trace option to configure. Added
500 memory allocation stack trace support. Added files
501 lib/silcutil/stacktrace.[ch]. Affected files are
502 lib/silcutil/silcmemory.[ch].
504 * Fixed memory leaks from libraries and server. Affected
505 files around the tree.
507 * Reverted back a fix made to CUMODE which broke it.
508 Affected file silcd/command.c.
510 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
512 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
513 core library, and implemented it. All textual messages SHOULD
514 use this flag and the message MUST be UTF-8 encoded.
515 All text messages sent by Irssi SILC client are now UTF-8
516 encoded (regardless whether the terminal supports UTF-8 or not).
517 Affected files are lib/silccore/silcchannel.h,
518 irssi/src/silc/core/silc-servers.c, silc-channels.c and
521 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
523 * Added lots of new statistics updating that was missing from
524 the server and router code. Affected files in silcd/.
526 * Sending SIGUSR1 signal to server now dumps the current
527 server statistics into /tmp directory. Affected file is
530 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
531 the SILC Hash Interface also. Added new functions
532 silc_hash_get_name, silc_hash_init, silc_hash_update and
533 silc_hash_final. Affected file lib/silccrypt/silchash.c.
535 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Added some better info printing for client during connecting.
538 Affected file silcd/server_util.c.
540 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
541 to silence a user on a channel. Affected files are
542 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
543 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
544 and silcd/packet_receive.c.
546 * Fixed a fatal bug in handling of malformed command payload.
547 Affected file silcd/command.c.
549 * Fixed a double free when announcing channel users to router.
550 Affected file silcd/server.c.
552 * After successful authentication to channel founder mode, check
553 that there isn't anyone else with founder mode on the channel.
554 The one that authenticated will become founder and anyone
555 else is demoted. Affected file silcd/command.c.
557 * Added error printing of any error that has occurred during
558 any command in client library. Affected file is
559 irssi/src/silc/core/client_ops.c.
561 * Removed some error printing from the client library and left
562 it for the application to worry (from the error status it
563 receives in 'command' client operation. Affected file is
564 lib/silcclient/command.c.
566 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
568 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
569 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
570 Starting key agreement with itself is denied. Affected file
571 is lib/silcclient/client_keyagr.c.

1087 Affected files is silcd/serverconfig.c.
1089 * Drop root privileges when started in foreground. Don't drop them
1090 if debugging also. Affected file is silcd/silcd.c.
1092 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1094 * Added more IM-like features by introducing new user modes
1095 for setting various presence information. Added new modes:
1096 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1097 specs and code. Protocol TODO #19. Affected files are
1098 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1099 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1101 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1103 * Added STATS command to the protocol after all, to return
1104 various statistical information about the network. It can
1105 be used by clients to retrieve statistical information, and
1106 servers may use it to to fetch cell and network wide
1107 statistics from router. Updated the protocol specs and
1108 implemented it to the server. Protocol TODO #16.
1109 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1110 silcd/command_reply.[ch].
1112 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1114 * The LIST command reply in client libary now adds new channel
1115 entry if the returned channel doesn't exist yet in cache,
1116 and returns the channel entry to the application in the
1117 command_reply client operation. Affected file is
1118 lib/silcclient/command_reply.c.
1120 * Changed the channel message payload's MAC generation to
1121 include the IV in the MAC as well. This way all relevant
1122 parts of the channel message payload are authenticated also
1123 with the channel message MAC (and not only by packet MAC).
1124 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1125 Affected file is lib/silccore/silcchannel.c.
1127 * Fixed the SKE to save the remote version, since the
1128 silc_ske_parse_version mistakenly checked wrong version,
1129 after it replaced the start payload. Affected files are
1130 lib/silcske/silcske.[ch].
1132 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1134 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1135 string utility functions. Added there also new functions
1136 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1137 Affected files lib/silcutil/silcstrutil.[ch].
1139 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1140 files are lib/silcutil/silcstrutil.[ch].
1142 * Defined that the security property fields in SKE SHOULD be
1143 UTF-8 encoded, defined that version string MUST be US-ASCII
1144 encoded, defined that passphrases sent in connection
1145 authentication protocol MUST be UTF-8 encoded. Implemented
1146 these to the client and server. Defined also that other
1147 passphrases sent in the protocol MUST be UTF-8 encoded.
1148 Affected files are lib/silcske/silcske.c,
1149 lib/silcclient/protocol.c, silcd/protocol.c,
1150 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1152 * Changed the silc_client_close_connection interface to not
1153 need the SilcSocketConnection which should not be visible
1154 to application. Affected files are lib/silcclient/client.c
1155 and lib/silcclient/silcclient.h.
1157 * Rewrote the text for Private Message Key Payload in the
1158 protocol specification. Protocol TODO #11.
1160 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Upgraded the protocol version to 1.1, updated protocol specs
1165 * Added the nickname as new argument to NICK_CHANGE notify and
1166 added it to protocol specs and implemented it to client and
1167 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1168 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1169 lib/silcclient/client_notify.c.
1171 * Added the killer's client ID to the KILLED notify and added
1172 it to protocol specs and implemented it to client and server.
1173 Protocol TODO #13. Affected files are silcd/command.c,
1174 silcd/packet_receive.c, packet_send.[ch],
1175 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1176 The killer's client entry is now returned to application in
1177 the `notify' client operation.
1179 * Fixed the Max Argument fields that had too large value set
1180 in the protocol specs. Protocol TODO #14.
1182 * Added the LEAVE command reply to return the ID of parted
1183 channel. Updated protocol specs and implemented it to the
1184 client and server. Protocol TODO #15. Affected files are
1185 silcd/command.c, lib/silcclient/command_reply.c. The channel
1186 entry is now returned to application in the `command_reply'
1189 * Rewrote the version SKE version checking in client libary
1190 and in server to use the silc_parse_version_string. Affected
1191 files are lib/silcclient/protocol.c, silcd/protocol.c.
1193 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1194 commands that was missing it, and updated protocol specs and
1195 the server implementation. Protocol TODO #10. The affected
1196 file is silcd/command.c.
1198 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1199 generic reply to a generic request (REQUEST flag), and
1200 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1201 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1202 to define the payload for DATA flag. Added the flags to
1203 the implementation. Protocol TODO #9. Affected file is
1204 lib/silccore/silcchannel.h.
1206 Changed the client library to return the message length
1207 to application as well in the channel_message and private_message
1208 client operations. Affected files are
1209 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1210 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1211 and lib/silcclient/client_ops_example.c.
1213 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1214 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1215 the channel. Updated protocol specs and impelemented this
1216 to client and server. Protocol TODO #6. Affected files are
1217 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1218 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1220 Added new options m and M to CMODE command in Irssi SILC
1221 client to set these modes.
1223 * Deprecated all administrative commands from SILC protocol
1224 since they are highly implementation specific commands.
1225 Updated protocol specs. Moved the old commands in
1226 implementations to private range of command types. Affected
1227 files are silcd/command.c, lib/silcclient/command.c and
1228 lib/silcclient/command_reply.c. Protocol TODO #8.
1230 * Fixed a bug in server where sending unknown command crashes
1231 the server. Affected file silcd/command.c.
1233 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1235 * Added SILC_PROTOCOLVERSION macro to check protocol version
1236 of a socket connection. The affected file is
1237 lib/silcutil/silcsockconn.h.
1239 * Added better error logging in rekey protocol. Affected file
1242 * Do not check public key types in SKE during rekey. Affected
1243 file lib/silcske/payload.c.
1245 * Fixed the rekey protocol with PFS, which was totally broken.
1246 Affected file silcd/protocol.c.
1248 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1250 * Some client implementations quit network by doing first LEAVE
1251 and then immediately SIGNOFF (like Bombyx). We now do check
1252 after a short time after LEAVE notify and check whether the
1253 client is still valid after LEAVE, and if not we remove it from
1254 cache. Affected file is lib/silcclient/client_notify.c.
1256 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1258 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1259 it's good not to have security holes here.
1261 * Fixed a negative refcount situtuation for the config context.
1262 Affected file is silcd/serverconfig.c.
1264 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1266 * ROBOdoc documented lib/silcutil/silcutil.h.
1268 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1270 * Optimized even more the SilcPacketContext structure. Now
1271 totally saved 16 bytes of memory per context after optimization.
1272 Affected files are lib/silccore/silcpacket.[ch].
1274 * Made strict checks for valid SILC IDs. Affected file is
1275 lib/silccore/silcid.c.
1277 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1279 * Changed the object argument for silc_cipher_register,
1280 silc_hash_register, silc_hmac_register and silc_pkcs_register
1281 to const. Affected files are lib/silccrypt/silccipher.[ch],
1282 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1284 * Changed the silc_get_username and silc_get_real_name to
1285 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1287 * Fixed the Irssi SILC Client to use the silc_get_username and
1288 silc_get_real_name insted of glib routines since the glib
1289 routines only corrupt stack. Fixes the Irssi SILC to work in
1290 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1292 * Fixed the Irssi to not use g_get_home_dir since it crashes
1293 or returns garbage on cygwin and corrupts stack. Added function
1294 get_home_dir to Irssi routines. Affected files are
1295 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1297 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1299 * Made some structure optimizations. SFTP memory FS MemFSEntry
1300 entry structure. Optimized SilcTask structure. Optimized
1301 SilcPacketContext structure.
1303 Affected files lib/silcsftp/sftp_fs_memory.c,
1304 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1306 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1308 * And yet again reverted back the config thing since Johnny
1309 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1312 * Fixed memory leaks from config object. Affected files are
1313 silcd/serverconfig.[ch].
1315 * Added support for adding new connections to the server in rehash.
1316 After rehash they take effect.
1318 Added support for changing the maximum allowed connections in
1319 rehash. The number can grow but going smaller is not supported.
1321 Added function silc_server_num_sockets_by_remote to the
1322 silcd/server_util.[ch].
1324 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1326 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1328 * Added preliminary checking during config parsing for a valid
1329 public/private key and removed further checks in the code.
1330 Affected files are silcd/serverconfig.[ch], server.c.
1332 * Moved functions silc_server_drop() and silc_server_daemonise()
1333 from server.c to silcd.c since they are stricly related to
1334 the application activity.
1336 * Reverted a small part of the automatic ref/unref since
1337 it caused a double unref in some situations. Affected
1338 files are silcd/silcd.[ch], server.c, serverconfig.c.
1340 * Added some .cvsignore files in the lib directory.
1342 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1344 * Fixed silc_net_gethostbyaddr to correctly resolve by
1345 address. Affected file lib/silcutil/silcnet.c.
1347 * Fixed the notify relaying to client. The HMAC to be used
1348 with relayed packets ws wrong and caused decryption failure
1349 at the client end. Affected file is silcd/packet_receive.c.
1351 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1353 * Created new branch silc_protocol_1_0_branch.
1355 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1357 * Changed the silc_server_config_* routines to be SilcServer
1358 independent. They are now officially application specific code
1359 and not part of generic server implementation. Affected files
1360 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1362 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1364 * Added automatic referencing of config context in the
1365 silc_server_config_alloc, and automatic unreferencing in the
1366 silc_server_config_destroy. Affected files are
1367 silcd/serverconfig.[ch], silcd/silcd.c.
1369 * Fixed the silc_log_quick handling in the logging routines.
1370 It didn't log quickly when it was TRUE. Affected file is
1371 lib/silcutil/silclog.c. Also the flush delay was set even
1372 if it was 0 in config file. Affected file is
1373 silcd/serverconfig.c.
1375 * Added support for changing key pair of the server in rehash.
1376 Affected file silcd/server.c.
1378 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1380 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1381 too early, before getting the channel entry. Affected file
1382 is silcd/packet_receive.c.
1384 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1386 * Added functions silc_server_config_[ref/unref], these are used
1387 to prevent that the config object is destroyed.
1389 No longer directly affect global variables silc_log_quick and
1390 silc_log_delay, they are first cached inside the config object
1391 and then applied with silc_server_config_setlogfiles().
1393 silc_server_config_set_defaults() is now internal to
1394 serverconfig.c, there are no reasons to show this internal stuff
1397 Affected files are silcd/serverconfig.[ch].
1399 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1400 fprintf's to stderr, since some code may be executed again after
1401 the server went into the background. Affected files are
1404 * Added rehash support. Added function silc_server_rehash() that
1405 will perform all the basic tasks of the rehashing procedure.
1407 * Added command line option `-x, --hexdump'. This will enable the
1408 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1409 The option `--hexdump' implies `--debug'.
1411 * Fixed a bad bug in the logging APIs (silcutil library) where
1412 the application would crash after calling silc_log_reset_all().
1414 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1416 * Fixed the KICKED notify handling in client library to
1417 correctly remove the channel and all entries from the
1418 channel when I was kicked. This bug crashed the client.
1420 Fixed yet another but in KICKED notify handling to remove
1421 the kicked client correctly from the channel.
1423 Affected file is lib/silcclient/client_notify.c.
1425 * Fixed a minor bug in looking up correct client entry
1426 in KICKED notify in server. Affected file is
1427 silcd/packet_receive.c.
1429 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1430 sources correctly to distribution. Fixes --with-gmp option.
1432 * Removed the manual rehashing from ID Cache, and changed it
1433 to use the SILC Hash Table's auto rehash feature. Affected
1434 file is lib/silccore/silcidcache.c.
1436 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1438 * Fixed a bug in the silc_client_nickname_format function that
1439 handles the multiple same nickname formatting. Two clients
1440 with same nickname caused problems after the first one left
1441 and rejoined. It didn't format the nickname correctly.
1442 Affected file is lib/silcclient/idlist.c.
1444 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1446 * Don't change the topic if olod topic is same as new one.
1447 Affected file is silcd/packet_receive.c.
1449 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1451 * Added cross-reference support to the SILC Documentation
1452 generator. All types across all HTML files are now cross-
1453 referenced. Affected files util/robodoc/generator.c and
1454 scripts/silcdoc/silcdoc.
1456 * Added file lib/silcutil/silctypes.h to include all the
1457 arithmetic type definitions and some macros. Removed
1458 includes/bitmove.h and moved macros to silctypes.h.
1460 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1462 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1466 * Added `type' argument to silc_id_payload_parse_id function which
1467 now returns the type of the ID to the sent pointer. Affected
1468 file is lib/silccore/silcid.[ch].
1470 * Added check for CMODE_CHANGE notify type that mode change is
1471 allowed by the sender. Affected file silcd/packet_receive.c.
1473 * Added check for CUMODE_CHANGE notify type that mode change is
1474 allowed by the sender. Affected file silcd/packet_receive.c.
1475 Added the ID type as CUMODE_CHANGE notify type as argument
1476 to the `notify' client operation. Affected files are
1477 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1479 * Added function silc_client_add_server to the client library.
1480 Added support for resolving also channel and server info when
1481 received unknown entity in notify packet. Affected files are
1482 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1484 * Added function silc_command_get_status to return the command
1485 status from the command reply's argument payload. Affected files
1486 are lib/silccore/silccommand.[ch].
1488 * Added check for KICKED notify type that the kicking is
1489 allowed by the client. Affected file silcd/packet_receive.c.
1491 * Created function silc_get_input which can be used to get input
1492 (echo on or off) from user on command line. Affected files are
1493 lib/silcutil/silcutil.[ch].
1495 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1497 * Optimized silc_server_packet_relay_to_channel function.
1498 Added new function silc_channel_message_payload_encrypt which
1499 can be called directly if channel message payload needs to
1500 be encrypted and is already encoded (no need to call _encode
1501 function). Packet relaying is now done by router without any
1502 extra memory allocations. Affected files are
1503 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1504 silcd/packet_send.c.
1506 * Fixed the INVITE notify handling. It took wrong arguments
1507 as invite list and invite delete. Affected file is
1508 silcd/packet_receive.c.
1510 * Added check for TOPIC_SET notify type that the topic change is
1511 allowed by the client. Affected file silcd/packet_receive.c.

1514 the client. Affected file silcd/packet_receive.c.
1516 * Changed the silc_server_client_on_channel to return the
1517 SilcChannelClientEntry as well. Moved the function
1518 silc_server_check_cmode_rights to server_util.[ch].
1519 Affected files are silcd/server_util.[ch], silcd/command.c.
1521 * Added function silc_server_check_umode_rights to check whether

1524 by the client. Affected files are silcd/server_util.[ch],
1525 silcd/packet_receive.c and silcd/command.c.
1527 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1529 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1530 ID length. It ignored that ID can be IPv6 based as well.
1531 Affected file lib/silccore/silcpacket.h.
1533 * Fixed the silc_id_id2str and silc_id_str2id to take the
1534 IPv6 address offset's into consideration. Affecte file is
1535 lib/silccore/silcid.c.
1537 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1539 * Fixed the internal Unix scheduler functions to check for
1540 NULL context they may receive. The affected file is
1541 lib/silcutil/unix/silcunixschedule.c.
1543 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1545 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1546 can specify different directory with --home command line
1547 parameter. Affected files irssi/src/silc/core/client_ops.c,
1550 * SILC-specific commands aren't now executed if the active server
1551 isn't of SILC-type, so there won't be problems with having
1552 IRC and SILC protocol support in same client. Affected files
1553 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1556 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1558 * Improved the signal support in SILC Schedule. Added new
1559 function silc_schedule_signal_call which is used by application
1560 to mark a signal to be called. It is now safe to perform
1561 any kind of tasks in signal callbacks since it is guaranteed
1562 that the application specified signal callback is called
1563 after the signal is over. Affected files are
1564 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1566 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1568 * Added `name' field to SilcChannelPrivateKey to represent
1569 application given name for the key. Moved also the context from
1570 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1571 Added the `name' argument also to the function
1572 silc_client_add_channel_private_key.
1574 Added function silc_client_current_channel_private_key to set the
1575 current channel private key in use.
1577 Added "change" command to KEY command which can be used to change
1578 the current channel private key. Bound the command also to
1579 alt+K (Alt+Shift+k).
1581 Also affected files lib/silcclient/client_channel.c,
1582 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1584 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Added silc_rng_get_byte_fast function in to the
1587 lib/silccrypt/silcrng.[ch].
1589 * Changed the interface of silc_packet_assemble and the
1590 silc_packet_send_prepare. If silc_packet_assmble is now
1591 called the application does not call silc_packet_send_prepare
1592 because the library will call it automatically. These
1593 interfaces now also return a reference to the outgoing buffer
1594 which includes the assembled packet, which the application can
1595 use to encrypt the packet.
1597 Affected files are lib/silccore/silcpacket.[ch],
1598 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1599 silcd/packet_send.c, server_backup.c and packet_receive.c.
1601 * Fixed a packet sending bug on very high load, where outgoing
1602 packet queue wasn't handled correctly and packets got corrupted.
1603 Affected files are lib/silcutil/*/silc*sockconn.c,
1604 lib/silcclient/client.c and silcd/server.c.
1606 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1608 * Added macro SILC_PACKET_DATALEN which can be used during
1609 packet assembling to check whether the data to be added to
1610 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1611 len is truncated until it fits it.
1613 Added checks for maximum length of channel message payload and
1614 private message payload also.
1616 Added checks for maximum packet length in server and in
1619 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1620 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1621 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1622 lib/silcclient/client_prvmsg.c.
1624 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Added silc_server_packet_queue_purge call to the
1627 silc_server_disconnect_remote to assure that all data in the
1628 queue before disconnecting is sent to the network. Affected
1629 file silcd/server.c.
1631 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1633 * Added the deleting of server's own ID cache entry to the
1634 silc_server_free function. Free also everything else that
1635 has been allocated in silc_server_init. The affected file
1638 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1640 * Added functions silc_parse_version_string, silc_version_to_num,
1641 and silc_ske_parse_version to parse SILC protocol style version
1642 strings. Affected files lib/silcutil/silcutil.[ch] and
1643 lib/silcske/silcske.[ch].
1645 * Added new configuration params: version_protocol, version_software
1646 and version_software_vendor to specify what version the remote
1647 host must at least be to be able to connect to server. The vendor
1648 string can be regex matched too. Added new function
1649 silc_server_connection_allowed to check maximum number of allowed
1650 connections, and allowed versions for incoming connections.
1651 Affected files are silcd/server.c, server_util.[ch] and
1654 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1656 * Added preliminary support for signals in scheduler. The
1657 signals we care about are now blocked always when the scheduler
1658 is locked. This way we can synchronise the use of signal with
1659 scheduler. It is guaranteed that when signal occurs the scheduler
1660 is not locked, and thus new tasks can be safely added to the
1663 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1664 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1665 Added new platform specific routines
1666 silc_schedule_internal_signals_[un]block and
1667 silc_schedule_internal_signal_[un]register.
1669 Added new functions to SILC Schedule API:
1670 silc_schedule_signal_[un]register. Each signal that application
1671 is going to use should be registered to the scheduler.
1673 Affected files are lib/silcutil/silcschedule.[ch],
1674 lib/silcutil/*/silc*schedule.c.
1676 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1678 * Check for unauthenticated client and server in the
1679 silc_server_new_client and silc_server_new_server functions.
1680 Affected file silcd/packet_receive.c.
1682 * Added function silc_string_is_ascii to check whether given
1683 string is 7-bit ASCII string. Affected files are
1684 lib/silcutil/silcutil.[ch].
1686 * Added function silc_id_is_valid_server_id into the
1687 silcd/serverid.c and added checking for valid Server ID's in
1688 silc_server_new_server. The Server ID must always be based
1689 on the server's public IP address.
1691 * Added logging of DISCONNECT packet message in the server.
1692 Affected file silcd/server.c.
1694 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1696 * Changed all library interfaces that use Global RNG to also
1697 accept SilcRng as argument. Affected files are
1698 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1699 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1700 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1701 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1702 lib/silccrypt/rsa.c.
1704 * Added function silc_pkcs_generate_key to the
1705 lib/silccrypt/silcpkcs.[ch] for applications so that they
1706 don't need to do pkcs->pkcs->init calls anymore.
1708 * Remove SilcSocketConnection from the SFTP API since it really
1709 wasn't needed there. The application has the information
1710 saved in its contexts anyway and the SFTP layer doesn't need
1711 know about it. Affected files lib/silcsft/silcsftp.h and
1712 lib/silcsftp/sftp_[server/client].c.
1714 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1715 The SilcSimContext is not SilcSim.
1717 * Fixed possible buffer overflows in silc_id_render in the
1718 lib/silcutil/silcutil.c.
1720 * On EPOC the global crypto module lists are not used at all
1721 in the crypto library. Added support for using the constant
1722 algorithm list on EPOC. Affected files are
1723 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1726 * Fixed the handling of third parameter of KICKED notify, since
1727 it was mistakenly updated to SILC Protocol 1.0 even though it
1728 is to be included in 1.1. Since it is not in 1.0 it is not
1729 mandatory, and this fix now handles it only if it is provided,
1730 and it is not error if it is not provided. Affected file
1731 lib/silcclient/client_notify.c.
1733 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1735 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1736 client. Affected file irssi/src/silc/core/client_ops.c.
1738 * Merged with Irssi 0.8.4 from irssi.org CVS.
1740 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1742 * Check for valid socket connection in client entries before
1743 sending any messages. Fixes a crash, but doesn't fix some
1744 other underlaying bug that is lurking there. Affected
1745 file silcd/packet_send.c.
1747 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1749 * $usermode, $cumode and $cumode_space expandos shouldn't do
1750 anything with non-SILC server records. Affected file
1751 irssi/src/silc/core/silc-expandos.c
1753 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1755 * Fixed the silc_net_check_[host/local]_by_sock to support
1756 IPv6 bound sockets as well. Now they can return IPv6 addresses
1757 as well. Affected file lib/silcutil/silcnet.c.
1759 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1760 Affected lib/silcutil/unix/silcunixnet.c.
1762 * Fixed ID rendering (at least on some platforms, not NetBSD)
1763 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1765 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1767 * Added silc_hash_public_key and silc_hash_public_key_compare
1768 functions to be used with SilcHashTable. They can be used to
1769 hash public keys and compare public keys in hash table. Affected
1770 file lib/silcutil/silcutil.[ch].
1772 * Added support for specifying multiple public keys for Client
1773 connection section in server configuration file. This makes it
1774 possible to accept multiple public keys from same host, or to
1775 make a section that accepts any incoming host, and have the
1776 accepted public keys listed in the section.
1778 Added functions silc_sever_[find/get]_public_key, added the
1779 support for this actually to all connection sections but only
1780 the Client section is currently allowed to specify multiple
1783 Affected files are silcd/server.c, server_internal.h,
1784 command.c, protocol.c, server_util.[ch], packet_receive.c.
1786 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1788 * Merged Irssi 0.8.2 from irssi.org CVS.
1790 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1792 * If silc_debug is TRUE, also output standard logging messages
1793 to stderr with the debug output.
1795 Made silc_log_reset_all() flushing all channels before returning.
1796 Also fixed some documentation typos.
1798 Affected files are lib/silcutil/silclog.[ch].
1800 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1802 * Fixed the server to check correctly the amount of connections
1803 from single host, by checking also the type of the connection.
1804 Fixed also the comparison of number of connections and number
1805 of allowed connections. Affected files are silcd/server.c,
1808 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1810 * Fixed the USERS command reply to save the user's mode on the
1811 channel as well. Fixed JOIN command reply to check whether a
1812 client is on channel already and not join it twice. Affected
1813 file lib/silcclient/command_reply.c.
1815 * Added new file silc-expandos.c into irssi/silc/core/ to return
1816 various stuff for various signal for the statusbar etc. updating.
1817 Now Irssi SILC client prints channel user modes etc. on the
1820 * The user mode (like server/router operator changes) is now shown
1821 on the Irssi SILC client's statusbar. The affected files are
1822 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1824 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1826 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1827 to SILC_SCHEDULE_[UN]LOCK macros.
1829 * Added more error printing to logs in server code. Affected
1830 files silcd/server.c and silcd/protocol.c.
1832 * Fixed -S option parsing in Irssi SILC Client. Affected file
1833 irssi/src/silc/core/silc-core.c.
1835 * Added silc_buffer_alloc_size function. Affected file is
1836 lib/silcutil/silcbuffer.h.
1838 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1840 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1841 constants. Affected files in
1842 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1845 * Changed the internal SFTP Memory FS table to const. Affected
1846 file lib/silcsftp/sftp_fs_memory.c.
1848 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1850 * Fixed the buffer formatting and unformatting routines to
1851 check the size of 64 bits types with sizeof(). Affected
1852 file is lib/silcutil/silcbuffmt.c.
1854 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1856 * Removed 0.6.x backwards support.
1858 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1860 * Changed all integer type names:
1861 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1862 to avoid collisions with other libraries using same type names
1865 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1867 * Added `prefer_ipv6' argument to the functions
1868 silc_net_gethostbyname[_async]. If it is TRUE it will return
1869 IPv6 address over IPv4. If FALSE IPv4 address is returned
1870 even if IPv6 address was found. Affected files
1871 lib/silcutil/silcnet.[ch].
1873 * Added support silc_net_create_connection[_async] to fallback
1874 to IPv4 address if IPv6 address could not be used (like if
1875 it doesn't work on a specific system). Affected file in
1876 lib/silcutil/unix/silcunixnet.c.
1878 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1880 * Added silc_schedule_reinit function to do the enlarging
1881 of the max tasks handling capabilities of the scheduler.
1882 Affected files lib/silcutil/silcschedule.[ch].
1884 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1886 * Added automatic extern "C" { ... } for C++ compilers so the
1887 application does not need to define them. Affected file
1888 includes/silcincludes.h.
1890 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1891 old name went against naming convention. Applications now
1892 include "silcclient.h" instead of "clientlibincludes.h".
1893 Removed includes/clientlibincludes.h, it is redundant now.
1895 * Renamed includes/version.h to silcversion.h.
1897 * Added really preliminary support for OS/2 into the util
1898 library. Only thread & mutex API is implemented, others
1899 are still to be implemented. Created the lib/silcutil/os2/
1900 directory. Created also file includes/silcos2.h.
1902 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1904 * Added preliminary BeOS support into the util library.
1905 Created lib/silcutil/beos/, and implemented all the needed
1906 functions to support SILC on BeOS. Created also file
1907 includes/silcbeos.h.
1909 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1911 * Added proper initializations to silc's irssi code, so it's
1912 now possible to load it as module. Affected files
1913 irssi/src/silc/core/silc-core.c,
1914 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1916 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1918 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1921 * Fixed the silcdoc document generator to correct generate
1922 docs from all kinds of filenames. Affected files are
1923 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1925 * ROBOdoc documented lib/silcutil/silcmemory.h.
1926 Added also new function silc_memdup.
1928 * Removed lib/silcutil/silcbufutil.h and moved those routines
1929 to the lib/silcutil/silcbuffer.h.
1931 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1933 * Added `user_count' to the SilcChannelEntry which now tells the
1934 number of users on the channel. The user count is now saved
1935 in normal server of global channels as well. Affected files
1936 silcd/server.c, idlist.h, packet_receive.c and command.c.
1938 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1939 include file utility functions.
1941 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1942 instead of calling directly OS routines.
1944 * Fixed NICK change printing in Irssi SILC Client. Fixed
1945 KICKED notify printing in Irssi SILC Client. Affected file
1946 irssi/src/silc/core/client_ops.c.
1948 * Fixed a NICK change bug in client library, to not recreate the
1949 client_entry->channels hash table everytime nick is changed.
1950 Affected file lib/silcclient/client.c.
1952 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1954 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1955 the SKE interface a bit.
1957 * Fixed padding problem in PKCS#1. The padding was not actually
1958 random since the random number generator was used incorrectly.
1959 This security bug affects only when encrypting with PKCS#1, and
1960 it is not currently used at all in SILC. SILC only use signing
1961 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1963 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1965 * Rewrote the notify handling in Irssi SILC client to not call
1966 the events as signals. Fixes problems with Perl support.
1967 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1969 * Send the auto-nicking NICK command in client library with
1970 little timeout after connecting. The affected file is
1971 lib/silcclient/client.c.
1973 * Added following new config file settings:
1974 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1975 key_exchange_timeout, conn_auth_timeout, connections_max,
1978 Implemented all the new config settings handling in the server.
1980 Optimized the use of SKE Mutual flag usage. Use it only
1981 if connection authentication protocol is not based in public
1984 Renamed all SilcServerConfigSection* to SilcServerConfig*
1985 to have a bit shorter names.
1987 Affected files silcd/serverconfig.[ch], server.[ch], and
1990 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1992 * Cleaned up the listening sockets code, preparing for the rehash
1993 support. Affected file is silcd/server.c.
1995 * Fixed some output messages. Affected files are silcd/silcd.c,
1998 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2000 * Create lib/doc/silcrng_intro.html document as introduction
2001 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2003 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2005 * Fixes to the silcd config template. Affected file is
2006 doc/example_silcd.conf.in.
2008 * Removed type casts from silc_calloc(), conforming to the
2009 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2011 * Removed param_name member from client, server, and router
2012 section structs, now identifying the param directly.
2014 Added CONFIG_FREE_AUTH macro in config file parsing.
2016 Affected files are silcd/serverconfig.[ch].
2018 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2020 * Fixed command line parameter handling. All SILC initialization
2021 is now done in silc_core_init() which also fixes autoconnecting
2024 Affected files irssi/src/silc/core/silc-core.c,
2025 irssi/src/fe-text/silc.c.
2027 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2029 * Added new configuration options and blocks:
2030 keepalive_secs, reconnect_count, reconnect_interval,
2031 reconnect_interval_max, reconnect_keep_trying and
2032 require_reverser_lookup. Added ConnectionParam block, and
2033 implemented the connection parameters when connecting as
2034 initiator and when accepting connections as responder.
2036 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2037 whether given configuration value has been given already.
2039 Affected files silcd/serverconfig.[c], server.[c].
2041 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2042 algorithm parts and created new file silcalgs.conf, that
2043 is now included from the example_silcd.conf.in.
2045 * Optimized the silc_server_connect_to_router_second to take
2046 the connection configuration object from the SilcServerConnection
2047 object instead of finding it during the connecting phase.
2048 Added the configuration object to SilcServerConnection struct.
2049 Affected files silcd/server_internal.h, server.c.
2051 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2053 * Add the client on channel after it was resolved at the
2054 channel message receiving, and it was not already on the
2055 channel. Affected file lib/silcclient/client_channel.c.
2057 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2059 * Fixed the public key authentication to allocate always the
2060 destination signature buffer instead of using static buffer.
2061 Affected file silcd/protocol.c.
2063 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2065 * Unified the serverconfig.[ch]'s helper function interface.
2066 Affected file silcd/serverconfig.[ch].
2068 * Removed doc/example_silc.conf.in since it is redundant.
2069 The make install will now install irssi/silc.conf file.
2071 * Added new Passphrase and Publickey authentication methods to
2072 config file, allowing both public key and passphrase based
2073 authentication to be set at the same time.
2075 Added `prefer_passphrase_auth' setting in config file which
2076 can be used to set to prefer passwd auth if both passwd and
2077 public key is set. If not set, public key is preferred.
2078 This has effect only when being initiator (responder will try
2081 Added support for authentication with passphrase and public key
2082 at the same time. The passphrase is tried first always since
2083 it is faster to check.
2085 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2087 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2089 * Merged the new SILC Config library, with the server parsing

2100 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2102 * The silc_cipher_register, silc_hash_register and
2103 silc_hmac_register now checks if the object to be registered
2104 is registered already. Affected files are
2105 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2107 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2113 * Allow zero length channel messages inside the Channel Message
2114 Payload. Affected file lib/silccore/silcchannel.c.
2116 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2117 as header filenames.
2119 * Removed lib/silcclient/README and created HTML file
2120 lib/silcclient/silcclient_using.html, which is now included
2121 as part of Toolkit documentation.
2123 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2125 * Fixed CUMODE_CHANGE notify handling to change the mode of
2126 correct client. Affected file lib/silcclient/client_notify.c.
2128 * Make silc_rng_alloc fail if it cannot allocate the sha1
2129 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2131 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2133 * Fixed the file transfer's key agreement payload to include
2134 zero port also if the hostname is NULL because it could not
2137 Call file transfer monitor callback now also if error occurs
2138 during key agreement protocol.
2140 Changed the silc_client_file_send interface to return the
2141 SilcClientFileError instead of session id. The session ID
2142 is returned into pointer provided as argument.
2144 Check that the file exists locally before sending the
2145 file transfer request at all.
2147 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2149 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2150 error than can occur while key agreement protocol. Affected
2151 file lib/silcclient/silcapi.h.
2153 * Fixed the event_mode CMODE handler to not crash when mode
2154 is changed and +k mode is set in the channel. Affected file
2155 irssi/src/silc/core/silc-channels.c.
2157 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2158 SILC_LOG_WARNING to give out Warning and not Error. Affected
2159 file lib/silcutil/silclog.c.
2161 * Fixed the channel message payload decryption in the function
2162 silc_channel_message_payload_decrypt to not modify the original
2163 buffer before it is verified that the message decrypted
2164 correctly. Otherwise, next time it is called with correct
2165 channel key it won't encrypt since the payload is corrupted.
2166 Affected file lib/silccore/silcchannel.c.
2168 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2170 * Do not constantly resize the window. A fix patch by cras.
2171 Affected file irssi/src/fe-text/screen.c.
2173 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2175 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2176 Affected file lib/silcutil/silcnet.c.
2178 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2180 * Fixed a bug in hash table internal routine for traversing
2181 the table with foreach callback. The current entry may
2182 become invalid in the callback but it was referenced after
2183 the callback returned.
2185 Do not allow auto rehashing of hash table during the
2186 silc_hash_table_foreach operation, for same reasons as it is
2187 not allowed for SilcHashTableList. Affected files are
2188 lib/silcutil/silchashtable.[ch].
2190 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2192 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2193 Win32 DLL. extern's in header files are now declared with
2196 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2198 * Fixed private message handling. It used some old code that
2199 caused the client to crash. Affecte file is
2200 lib/silcclient/client_prvmsg.c.
2202 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2204 * Added function silc_client_add_channel,
2205 silc_client_replace_channel_id, and removed functions
2206 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2207 from client library.
2209 * Added cross reference of the joined channels to the
2210 SilcClientEntry, and changed the SilcChannelEntry's
2211 users list to SilcHashTable. The affected files are
2212 lib/silcclient/idlist.[ch].
2214 * Fixed a bug in hash table tarversing. While the hash table
2215 is traversed with SilcHashTableList the table must not be
2216 rehashed. It is now guaranteed that auto rehashable tables
2217 are not rehashed while tarversing the list. Also defined that
2218 silc_hash_table_rehash must not be called while tarversing
2219 the table. Added function silc_hash_table_list_reset that must
2220 be called after the tarversing is over. The affected files are
2221 lib/silcutil/silchashtable.[ch].
2223 * Changed all hash table traversing to call the new
2224 silc_hash_table_list_reset in server and in client library.
2226 * Added function silc_client_on_channel to return the
2227 SilcChannelUser entry if the specified client entry is joined
2228 on the specified channel. This is exported to application as
2229 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2231 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2233 * Fixed founder regaining problem with JOIN command on normal
2234 server. The notify for mode change must be sent always and
2235 not only if !cmd->pending. Affected file silcd/command.c.
2237 * Fixed the WHOWAS command's reply sending to support the
2238 lists correctly. Affected file silcd/command.c.
2240 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2242 * When sending JOIN command to router for processing the
2243 sender's old command identifier was not saved back to the
2244 sender's command context, fixed now. The affected file is
2247 * Create the key in JOIN command of the router did not return
2248 the channel key, added check for this. Affected file is
2251 * Fixed a channel ID update bug in JOIN command reply. Do
2252 not directly upgrade the ID but call the function
2253 silc_idlist_replace_channel_id if the ID was changed.
2254 Affected file silcd/command_reply.c.
2256 * Fixed memory leaks from command calling if it would fail.
2257 Affected file silcd/command.c.
2259 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2261 * Applied patches from cras:
2263 Memory leak fixes around libaries, irssi window resize fix,
2264 new silclist.h and silcdlist.h, all extern inline changed to
2267 * Removed dotconf from lib/dotconf, not needed anymore.
2269 * Removed TRQ from lib/trq, not needed anymore.
2271 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2272 with server connections. Later this will be configurable
2273 in config file after new config file is done. Affected file
2276 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2278 * Fixed a crash in server related to channel announcements.
2279 Affected file silcd/server.c.
2281 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2283 * Fixed memory leaks in silc_server_create_new_channel*
2284 functions. Affected file silcd/server.c.
2286 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2287 which ID was changed. This way the router will send the
2288 user list for the channel again, and server won't be in
2289 desync in some rare circumstances. Affected file is
2290 silcd/packet_receive.c.
2292 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2294 * Check for NULL socket pointer in the function
2295 silc_server_packet_send_to_channel_real. Affected file
2296 silcd/packet_send.c.

2299 list. Affected file silcd/packet_receive.c.
2301 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2303 * Fixed some header addition to Toolkit distribution in
2304 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2306 * Added lib/silcclient/client_ops_example.h as an template
2307 file for application programmers to quickly start using
2308 the SilcClientOperation functions in their application.
2309 Updated the lib/silcclient/README as well to tell about this
2310 nice file made available.
2312 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2314 * Call silc_server_remove_from_channels when removing client
2315 entry when NO_SUCH_CLIENT_ID was received. Affected file
2316 is silcd/command_reply.c.
2318 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2320 * Added server & router operator statistics updating. Affected
2321 file silcd/packet_receive.c and silcd/command.c.
2323 * Fixed the SERVER_SIGNOFF notify handling on normal server
2324 not to save the history information for clients. Same was
2325 fixed earlier in remove_clients_by_server function, but not
2326 here. Affected file silcd/packet_receive.c.
2328 * Raised the default connection-retry count from 4 to 7 in
2329 server. Affected file silcd/server.h.
2331 * Cancel any possible reconnect timeouts when we start the
2332 key exchange. Affected file silcd/server.c.
2334 * Do not reconnect on connection failure when SCONNECT was
2335 given. Affected files silcd/server.[ch].
2337 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2339 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2341 * Fixed the NICK command to always give the unformatted
2342 nickname to the one giving the NICK command. If unformatted
2343 nickname is cached already it will be formatted and the
2344 local entry will always get the unformatted nickname.
2345 Affected file lib/silcclient/idlist.c.
2347 * Fixed some double frees from client library commands.
2348 Affected file is lib/silcclient/command.c.
2350 * Fixed CUMODE command in server to assure that no one can
2351 change founder's mode than the founder itself, there was a
2352 little bug. Affected file silcd/command.c.
2354 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2356 * Removed the SilcClientCommandDestructor from the client
2357 libary, it is not needed anymore. Affected files are
2358 lib/silcclient/silcapi.h, command[_reply].[ch],
2359 client_notify, idlist.c.
2361 * Fixed GETKEY command to first resolve client, and then
2362 resolve the server only if the client was not found, instead
2363 of resolving both at the same time. Affected file is
2364 lib/silcclient/command.c.
2366 * Added silc_client_start_key_exchange_cb and lookup the
2367 remote hostname and IP address before starting the key
2368 exchange with server. The affected file is
2369 lib/silcclient/client.c.
2371 * The server's public key is now saved using the IP address
2372 of the server and not the servername for the filename.
2373 The hostname public key filename is checked as an fall back
2374 method if the IP address based filename is not found.
2376 Fixed the GETKEY command to save the fetched server key
2377 in correct filename.
2379 Print the remote server's hostname now when new key is
2380 received during connection process. Affected file is
2381 irssi/src/silc/core/client_ops.c.
2383 * Return always our own public key to the client if it asks
2384 for it with GETKEY command. Affected file silcd/command.c.
2386 * Removed the use_auto_addr variable from default config
2387 file since it was in wrong section. Affected file is
2390 * Fixed TOPIC_CHANGE notification to not route it when it
2391 was sent using silc_server_send_notify_to_channel function.
2392 Affected file silcd/command.c.
2394 * Fixed silc_server_send_notify_kicked to send the kicker's
2395 Client ID also, it was missing. Affected files are
2396 silcd/command.c, silcd/packet_send.[ch].
2398 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2400 * Do not save client history information in SERVER_SIGNOFF.
2401 Fixes the bug in normal server that it does not detect
2402 the client becoming valid after the server becomes back
2403 online. Affected file silcd/server_util.c.
2405 * Added `sock_error' field into the SilcSocketConnection
2406 context. When error occurs during socket operation (read
2407 or write) the error is saved. Added also new function
2408 silc_socket_get_error to return human readable socket error
2409 message. Affected files are lib/silcutil/silcsockconn.[ch],
2410 lib/silcutil/unix/silcunixsockconn.c, and
2411 lib/silcutil/win32/silcwin32sockconn.c.
2413 * The server now prints the socket error message in the
2414 signoff for client. Affected file silcd/server.c.
2416 * Fixed the `created' channel information sending from router
2417 to server in JOIN command. Checks now whether the channel
2418 really was created or not and set it according that.
2420 Fixed the JOIN command to use the client entry's current
2421 ID during the joining procedure instead of the one it sent
2422 in the command (it is checked though), since it can change
2423 between the packet processing and command processing, and
2424 would just case unnecessary pain in the client end. Affected
2425 file silcd/command.c.
2427 * Fixed a channel key payload sending to use correct channel
2428 ID when the server was forced to change the channel's ID by
2429 router. Router sent the key payload with the old Channel ID.
2430 Affected file silcd/packet_receive.c.
2432 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2434 * Call silc_server_save_channel_key only if the key payload
2435 was provided in the JOIN command's command reply. Affected
2436 file silcd/command_reply.c.
2438 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2440 * Fixed silc_mp_sizeinbase to return the value correctly with
2441 MPI. Affected file lib/silcmath/mp_mpi.c.
2443 * Fixed the stop_server signal to correctly stop the scheduler
2444 and gracefully stop the server when SIGTERM or SIGINT signals
2445 are received. Affected file silcd/silcd.c.
2447 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2449 * Simple handling of TERM and HUP signals. Also added some log
2450 flushing call around. Affected file is
2453 * Fixed small bugs in silclog.c. Now buffering output will take
2454 effect after 10 seconds since startup: This will ensure that
2455 no important startup messages are lost. Also output redirection
2456 will preserve original format ([Date] [Type] message).
2457 Affected file is lib/silcutil/silclog.c.
2459 * Added two options to the config file, in the logging section:
2460 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2461 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2463 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2465 * Do not print the warning about log files not being initialized
2466 more than once to avoid excess logging. Affected file is
2467 lib/silcutil/silclog.c.
2469 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2470 the SIM copying in make install in Makefile.am.pre.
2472 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2474 * Rewritten silclog APIs. Globally interesting changes follows:
2475 silc_log_set_files() changed to silc_log_set_file().
2476 silc_log_set_callbacks() changed to silc_log_set_callback().
2477 ROBOdoc documented silclog header file.
2478 SilcLogCb now returns bool to wether inihibit the default
2479 handler or not (to keep the old behaviour return always TRUE).
2480 The new APIs should also fix the problem of the
2481 silcd_error.log file that was written in the current directory.
2484 Log files streams will remain opened after silc_log_set_file()
2485 call, means less CPU usage notably on high traffic servers.
2486 File streams are now full buffered, and flushed to the disk
2487 every 5 minutes, lesses HD activity and CPU usage.
2488 Messages can be redirected, allowing admins to configure
2489 one single logfile for all server messages.
2490 the silc_log_quick global variable to activate fast-logging.
2491 Affected files lib/silcutil/silclog.[ch]
2493 * Changed some code to conform new silclog APIs. Affected
2494 files are doc/example_silcd.conf.in, silcd/server.c
2495 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2498 * Fixed a memory leak that could occur in some situations.
2499 Affected file silcd/serverconfig.c.
2501 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2503 * Added the silc_client_del_client to remove the client from
2504 all channels as well. Affected file lib/silcclient/idlist.c.
2506 * Fixed the client library to correctly remove the client
2507 from all channels when the client entry is being destroyed.
2508 Affected file lib/silcclient/client_notify.c, command.c.
2510 * Added auto-nicking support to the client library. If the
2511 applicatio now sets client->nickname it will be sent to the
2512 server after connecting by the library. This way for example
2513 SILCNICK (or IRCNICK) environment variables will have effect
2514 and always change the nickname automatically to whatever
2515 it is wanted. Affected file lib/silcclient/client.[ch].
2517 * Renamed silc_server_command_bad_chars to the
2518 silc_server_name_bad_chars and moved it to the
2519 silcd/server_util.[ch]. Added also new function
2520 silc_server_name_modify_bad to return nickname that
2521 includes bad characters as new nickname without those
2522 bad characters. This check and modify is now used in
2523 silc_server_new_client when the username is initially set
2524 as nickname, so it must be checked to be valid nickname.
2525 Affected file silcd/packet_receive.c.
2527 * The nickname length is now taken from the packet for real
2528 and not trusted to strlen() since it clearly can return
2529 wrong length for nickname including bad characters. This
2530 also applies to channel names. Affected file silcd/command.c.
2532 * Removed the lib/silcsilm/modules directory. Modules are now
2533 compiled into the lib/silcsim. Fixed the copying of the
2534 modules to follow symbolic links in Makefile.am.pre.
2536 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2538 * Fixed silc_string_regexify list creation. Fixes bugs with
2539 BAN and INVITE commands in server. The affected file is
2540 lib/silcutil/unix/silcunixutil.c.
2542 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Removed the command destructor entirely from the server's
2545 command and command reply routines. It is not needed, and
2546 its usage was buggy and caused crashes. Affected files are
2547 silcd/command[_reply].[ch].
2549 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Cancel protocol and NULL sock->protocol if timeout
2552 occurred during protocol. Affected file silcd/server.c.
2554 * Cancel protocol timeouts always before calling the final
2555 callback, to assure that after final callback is called
2556 no other state will be called for the protocol anymore.
2557 Affected file silcd/protocol.c.
2559 * Print error log if incoming connection configuration could
2560 not be found. Affected file silcd/server.c.
2562 * Fixed JOIN command to correctly save the founder mode
2563 to the client on normal SILC server, when the channel
2564 was created by the router. Affected file silcd/command.c.
2566 * Fixed LIST command (hopefully) to send correct reply
2567 packets. Affected file silcd/command.c.
2569 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * The silc_packet_receive_process now returns FALSE if the
2572 read data was invalid packet, and TRUE if it was ok.
2574 The server now checks that if unauthenticated connection
2575 sends data and its processing fails the server will close
2576 the connection since it could be a malicious flooder.
2578 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2580 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Make sure the warning about error opening a log file is
2583 printed only once and not everytime it fails (produces
2584 too much useless log). Affected file lib/silcutil/silclog.c.
2586 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2588 * Made the silc_server_daemonise() function more readable.
2589 Affected file silcd/server.c.
2591 * Pid file is now optional, the user may comment it out from
2592 the config file. Removed define SILC_SERVER_PID_FILE, we
2593 don't need a default any longer. Affected file
2594 configure.in.pre, lib/Makefile.am.pre.
2596 * Make some use of the pid file. The server now dies at startup
2597 if it detects a valid pid file on his path. The server would
2598 die anyway in this circumstance, because of the bind() failure.
2599 Affected file silcd/silcd.c.
2601 * No longer compiling lib/dotconf.
2603 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Fixed JOIN command parsing not to crash. Affected file
2606 lib/silcclient/command.c.
2608 * Fied the NICK_CHANGE notify to add the new client entry
2609 even it is resolved. This removes an <[unknown]> nick
2610 thingy bug in the client. Affected file is
2611 lib/silcclient/client_notify.c.
2613 * Do not try to allocate 0 bytes (efence does not like it)
2614 in lib/silccore/silccomand.c when encoding payload.
2616 * Do not take IRCNICK as nickname in Irssi SILC client since
2617 it is not possible to set nickname before hand connecting
2618 the server (TODO has an entry about adding auto-nicking
2621 * Changed the silc_server_command_pending to check whether
2622 there already exists an pending entry with the specified
2623 command, command identifier and pending callback. This is
2624 to fix IDENTIFY and WHOIS related crashes that may register
2625 multiple pending commands with same identifier. Affected
2626 file silcd/command.c.
2628 * Fixed the server to reconnect to the router even if it
2629 was already reconnecting and EOF was received. This to
2630 fix a possibility that the server wouldn't ever try to
2631 auto-reconnect to the router. Affected file silcd/server.c.
2633 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * Fixed the server's password authentication to use the
2636 length of the locally saved password, and not the one
2637 sent in the packet. Affected file silcd/protocol.c.
2639 * Fixed same password authentication problem in the
2640 Authentication Payload handling routines in
2641 lib/silccore/silcauth.c.
2643 * Yet another password authentication problem fixed with
2644 channel password handling in silcd/command.c.
2646 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * If first character of string in silc_parse_userfqdn is '@'
2649 then do not parse it. Affected file is
2650 lib/silcutil/silcutil.c.
2652 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Fixed minor bug in IDENTIFY command reply sending, which
2655 caused various weird problems during JOIN when it was
2656 resolving names for users. Affected file silcd/command.c.
2658 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2660 * Fixed the IDENTIFY command reply sending to chech better valid
2661 clients. It was possible to send incomplete list of replies.
2662 Affected file silcd/command.c.
2664 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Added silc_client_command[s]_[un]register functions now to
2667 dynamically register the commands in client library. Removed
2668 the static table of commands. This allows the client library
2669 to call commands without causing the application to know about
2670 what commands library has called.
2672 Removed the INFO command reply kludge to detect when the command
2673 was called by library. Now library use its own command reply
2674 function for INFO command.
2676 Added function silc_client_command_call to call a command.
2677 Application can use it to call command, not access the structure
2680 Now all commands that are sent by the client library (not
2681 explicitly sent by application) use own command reply functions.
2683 Affected files around lib/silcclient/ and in
2684 irssi/src/silc/core/.
2686 * Fixed the WHOIS command reply sending to chech better valid
2687 clients. It was possible to send incomplete list of replies.
2689 Fixed the WHOIS and IDENTIFY to send the request to router
2690 if normal server did not do it and did not find any results.
2692 Affected file silcd/command.c.
2694 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Moved the internal data from SilcClient context into its
2697 own file, not accesible to application. Affected files
2698 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2699 and other files in client library.
2701 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Added doc/examples installation target in Makefile.am.pre.
2706 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2708 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2709 commands the found client entry will be removed from the
2710 cache, after notifying application about the error. Affected
2711 file lib/silcclient/command_reply.c.
2713 * Changed the /MSG to check for exact nickname user gave, and
2714 not let `nick' match `nick@host' if it is only one found. Now,
2715 user must type the exact nickname (like nick@host2) even if
2716 there are no more than one same nicks found. This is to avoid
2717 a possibility of sending nickname to wrong nickname since
2718 `nick' could match `nick@host'. Affected file is
2719 irssi/src/core/silc-servers.c.
2721 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Do not print "you are now server operator" or similar when
2724 giving /away command. Affected files are
2725 irssi/src/silc/core/client_ops.c, silc-servers.h.
2727 * Made the silc_server_command_pending_error_check to send
2728 the same command reply payload it received back to the
2729 original sender of the command. This way all arguments
2730 that was received by the server will be received by the
2731 client too. Affected file silcd/command.c.
2733 * Added the silc_idcache_add to return the created cache entry
2734 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2736 * Add global clients to expire if they are not on any channel.
2737 This is because normal server will never know if they signoff
2738 if they are not on any channel. The cache expiry will take
2739 case of these entries. This is done by normal servers only.
2740 The affected files are silcd/command_reply.c,
2741 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2743 * If server receives invalid ID notification for WHOIS or
2744 IDENTIFY and the ID exists in the lists, it is removed.
2745 Affected file silcd/command_reply.c.
2747 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2748 in client then client entry that it matches is searched and
2749 the nickname is printed on the screen for user. Affected
2750 file irssi/src/silc/core/client_ops.c.
2752 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Use cache entry expire time in the LIST command reply to
2755 purge old entries from the cache after the LIST command
2756 reply has been received. This way we don't have non-existent
2757 entries in the cache for too long. Affected file is
2758 silcd/command_reply.c.
2760 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * If we are normal server, and we've not resolved client info
2763 in WHOIS or IDENTIFY from router, and it is global client,
2764 we'll check whether it is on some channel. If it is not
2765 then we cannot be sure about its validity and will resolve it
2766 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2767 file silcd/command.c.
2769 * Search channel by name (if possible) rather than by ID
2770 in IDENTIFY command's command reply. Affected file is
2771 silcd/command_reply.c.
2773 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2775 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2776 Updated specs and implemented it. Affected file silcd/command.c,
2777 silcd/packet_send.c and silcd/packet_receive.c.
2779 * Implemented the <founder auth> payload handling in the JOIN
2780 command. If provided all conditions for channel joining
2781 except requirement to provide correct passphrase can be
2782 overrided by the channel founder. Updated the protocol specs.
2783 Affected file silcd/command.c.
2785 Added support for founder auth in JOIN command in client
2786 library. Fixed the parsing of the JOIN command now to support
2787 all options as they should be. The affected file is
2788 lib/silcclient/command.c.
2790 * Optimized the WHOIS and IDENTIFY commands to send the request
2791 to router only if it includes nicknames or other names. If
2792 they include only IDs then check the local cache first before
2793 routing. Affected file is silcd/command.c.
2795 * Added channels topic announcements. Affected file is
2796 silcd/packet_receive.c and silcd/server.c.
2798 * Fixed the silc_server_send_notify_topic_set to really destine
2799 the packet to channel. Affected file silcd/packet_send.c.
2801 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2802 library. Affected file lib/silcclient/client_notify.c.
2804 * Added UMODE announcements. Affected file silcd/server.c.
2806 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2808 * Memory leak fixes in:
2810 lib/silcutil/silcsockconn.c
2811 lib/silcske/silcske.c
2812 lib/silcske/groups.c
2814 lib/silccrypt/silcpkcs.c
2815 lib/silccore/silccommand.c
2816 lib/silccore/silcidcache.c
2821 * ROBOdoc documented the lib/silcske/groups.h file and a
2822 bit changed the interface for better.
2824 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2826 * Update the client entry context in the ID cache after
2827 nick change. Affected file lib/silcclient/command.c.
2828 Fixes the CUMODE command when regaining founder privileges,
2829 and a little WHOIS problem.
2831 * Fixed silc_net_gethostbyname to correctly call the
2832 inet_ntop. Affected file lib/silcutil/silcnet.c.
2834 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2836 * Added IPv6 support checking to the configure.in.pre, added
2837 also --enable-ipv6 option to override the check. Affected
2838 file configure.in.pre.
2840 * The silc_thread_create now calls the start function
2841 directly if threads support is not compiled in. Removes
2842 ugly #ifdef's from generic code. Affected files are
2843 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2845 * Added silc_net_gethostby[name/addr]_async to asynchronously
2846 resolve. Affected files are lib/silcutil/silcnet.[ch].
2848 * Added support for rendering IPv6 based server, client and
2849 channel IDs. Affected file lib/silcutil/silcutil.c.
2851 * Added support for creating IPv6 based server IDs. Affected
2852 file is silcd/serverid.c.
2854 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2856 * Added silc_net_gethostby[addr/name] into the
2857 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2858 routines. Added silc_net_is_ip[4/6]. Affected file is
2859 lib/silcutil/unix/silcunixnet.c. All routines that take
2860 address as argument now supports both IPv4 and IPv6 addresses.
2862 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2864 * Fixed LIST command reply sending in server. Affected file
2867 * Server now sends the kicker's client ID in the KICK notify
2868 to the kicked client. Affected file silcd/command.c.
2870 * The client library now parses the kickers client ID and
2871 UI displays it. Affected files lib/silcclient/client_notify.c
2872 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2874 * Made all payload parsing function prototypes consistent.
2875 They all take now const unsigned char * and uint32 pair as
2876 the payload data instead of SilcBuffer. Changes all around
2877 the source tree. Other unsigned char* -> const unsigned char*
2878 changes around the tree as well.
2880 * Optimized SFTP client and server packet sending not to
2881 allocate new buffer for each packet but to recycle the
2882 first allocated buffer. Affected files are
2883 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2885 * Optimized the SFTP client to use SilcList instead of
2886 SilcDList for requests, because it is faster. Affected file
2887 is lib/silcsftp/sftp_client.c.
2889 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2890 into lib/silccore/silcid.[ch].
2892 Renamed silcpayload.[ch] into silcargument.[ch].
2894 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * If client entry is deleted with active key agreement
2897 session, abort the session.
2899 The silc_client_abort_key_agreement now calls the completion
2900 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2902 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2905 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Don't use __restrict in older GCC's. Affected file is
2908 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2910 * silc_net_localhost now attempts to reverse lookup the
2911 IP/hostname. Affected file lib/silcutil/silcnet.c.
2913 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2914 command. It can be used to gain founder privileges at
2915 the same time when joining the channel.
2917 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2918 kicker's client ID as well. Updated protocol specs.
2920 Defined that the server must send SILC_COMMAND_IDENTIFY
2921 command reply with error status to client who sent
2922 private message with invalid client ID.
2924 Updated the protocol specification.
2926 * Added silc_server_send_command_reply to send any
2927 command reply. Affected file silcd/packet_send.[ch].
2929 * Added silc_id_payload_encode_data to encode ID payload
2930 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2932 * The server now send IDENTIFY command reply with error
2933 status if client ID in private message is invalid. Affected
2934 file silcd/packet_receive.c.
2936 * Save the server key file with server's IP address in
2937 the filename instead of hostname. The affected file is
2938 irssi/src/silc/core/client_ops.c.
2940 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2945 * Added libtool support for compiling shared objects in
2946 lib/silcsim. Affected file configure.in.pre and
2947 lib/silcsim/Makefile.am. Original patch by cras.
2949 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Pid file configuration, and server's config file fixes
2952 patch by toma. Updated CREDITS file.
2954 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2956 * Fixed silc_client_channel_message to not try to decrypt
2957 the message twice if it resolved the destination client
2958 information. This could cause of dropping one channel
2959 message. Affected file lib/silcclient/client_channel.c.
2961 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2964 lib/silcclient/client.c. This function is used when the SILC
2965 Client is run under some other scheduler, or event loop or
2966 main loop. On GUI applications, for example this may be
2967 desired to used to run the client under the GUI application's
2968 main loop. Typically the GUI application would register an
2969 idle task that calls this function multiple times in a second
2970 to quickly process the SILC specific data.
2972 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2974 * Fixed silc_server_drop() for dropping the supplementary
2975 groups as well, this could cause a security hole on some
2978 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2983 * Write PID file after dropping privileges. Added -F option
2984 to run server on foreground. A patch by debolaz.
2985 Affected files silcd/server.c, silcd/silcd.c.
2987 * Fixed MOTD to return the MOTD file server name. Affected
2988 file silcd/command.c.
2990 * Added INFO command reply handling to the Irssi SILC Client.
2991 Affected file irssi/src/silc/core/client_ops.c.
2993 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Fixed the silc_idcache_list_* routines to really support
2996 the dynamic list. Fixes a crash. Affected file is
2997 lib/silccore/silcidcache.c.
2999 * Fixed the LIST command reply to really call LIST command's
3000 pending callbacks. Affected file silcd/command_reply.c.
3002 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Update conn->local_entry->nickname after giving NICK
3005 command. Affected file lib/silcclient/command.c.
3007 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3009 * Added the [pid] option to the silcd configuration file
3011 Affected files: serverconfig.[ch] and silcd.c
3013 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Save fingerprint in WHOIS command reply in server.
3016 Affected file silcd/command_reply.c.
3018 * Fixed NICK commands pending callback registration.
3019 Affected file lib/silcclient/command.c.
3021 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Use ++server->cmd_ident when sending commands in server,
3024 instead of random number. Affected file silcd/command.c.
3026 * Fixed GETKEY command reply to call actually GETKEY pending
3027 command callbacks. Affected file silcd/command_reply.c.
3029 * A bit stricter check for nicknames. Check for same nickname
3030 in NICK command also. Affected file silcd/command.c.
3032 * Do not call INFO command everytime client ID changes, only
3033 during first connecting. Affected file lib/silcclient/client.c.
3035 * Set the new nickname only after successful command reply for
3036 NICK command is returned by server. Affected file
3037 lib/silcclient/command.c.
3039 * Remove nicknames from nicklist during server_signoff notify.
3040 Should fix /NAMES bit more. The affected file is
3041 irssi/src/silc/core/silc-channels.c.
3043 * Added `fingerprint' field to the SilcIDListData in the
3044 silcd/idlist.h to hold the fingerprint of the client's
3047 Send the fingerprint of the client's public key in WHOIS
3050 Affected files silcd/command.c, and silcd/idlist.[ch].
3052 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3053 create fingerprint from given data.
3055 * Show the fingerprint of the client's public key in WHOIS.
3056 Affected files irssi/src/module-formats.[ch] and
3057 irssi/src/silc/core/client_ops.c.
3059 * Format the multiple same nicknames also during JOIN and
3060 NICK_CHANGE notifys. Affected file is
3061 lib/silcclient/client_notify.c.
3063 * Do not print error on screen for invalid private message
3064 payload since it can come if someone is sending private
3065 messages with wrong key. Affected file
3066 lib/silccore/silcprivate.c.
3068 * Fixed multiple concurrent /PING crash. Affected file
3069 lib/silcclient/command.c.
3071 * Changed the wrong ID encoding. All IP addresses must be
3072 in MSB first order in encoded format. They were encoded
3073 wrong and was in LSB format. Affected files are
3074 silcd/serverid.c, lib/silcutil/silcutil.c.
3076 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3078 * Call the `connect' client operation through the scheduler
3079 in case of error. Affected file lib/silcclient/client.c.
3081 * Call the `failure' client operation even if the error
3082 occurred locally during a protocol. Affected file is
3083 lib/silcclient/protocol.c.
3085 * Added support of sending LIST command to router from normal
3086 server. This way normal server can get list of all channels
3087 in the network too. Fixed the channel list sending in the
3088 server too. Affected files are silcd/command.c, and
3089 silcd/command_reply.[ch].
3091 * Added silc_server_update_channels_by_server and
3092 silc_server_remove_channels_by_server. They are used during
3093 disconnection of primary router and in backup router protocol.
3094 Affected file silcd/server_util.[ch], silcd/server.c and
3095 silcd/server_backup.c.
3097 * Fixed channel adding to global list in IDENTIFY command
3098 reply in server. Affected file silcd/command_reply.c.
3100 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * If the incoming packet type is REKEY or REKEY_DONE process
3103 that packet always synchronously. Fixes yet another MAC
3104 failed error on slow (dialup) connections. Affected file
3105 lib/silcclient/client.c and silcd/server.c.
3107 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Call check_version SKE callback for initiator too. Affected
3110 file lib/silcske/silcske.c.
3112 * Implemented fix for security hole found in the SKE that was
3113 fixed in the specification few days back; the initiator's
3114 public key is now added to the HASH value computation.
3115 Added backwards support for the old way of doing it too, for
3116 old clients and old servers. Affected file is
3117 lib/silcske/silcske.c.
3119 * Enabled mutual authentication by default in SKE. If initiator
3120 is not providing mutual authentication the responder will
3121 force it. This will provide the proof of posession of the
3122 private key for responder. The affected files are
3123 lib/silcclient/protocol.c and silcd/protocol.c.
3125 * Do not cache anymore the server's public key during SKE.
3126 We do mutual authentication so the proof of posession of
3127 private key is done, and if the server is authenticated in
3128 conn auth protocol with public key we must have the public
3129 key already. Affected file silcd/protocol.c.
3131 * Added new global debug variable: silc_debug_hexdump. If
3132 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3133 file lib/silcutil/silclog.[ch].
3135 * Fixed compilation warning due to char * -> const char *.
3136 Affected files lib/silcutil/silcnet.h, and
3137 lib/silccore/silcauth.[ch].
3139 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * Fixed CMODE command when new channel key was created. If
3142 the creation failed the old key was removed. Next time giving
3143 same command would crash the server since the old key was
3144 freed already. Affected file silcd/command.c.
3146 * Fixed the silc_server_announce_get_channels to not crash
3147 on reconnect. Affected file silcd/server.c.
3149 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Added silc_log_set_debug_string function to set a regex
3152 string to match for debug output. Only the function names,
3153 or filenames matching the given debug string is actually
3154 printed. This way it is possible to filter out those debug
3155 strings that user is not interested in.
3157 Fixed a bug in silc_string_regexify.
3159 Affected files lib/silcutil/silclog.[ch], and
3160 lib/silcutil/unix/silcunixutil.c.
3162 * Changed the -d options in both server and Irssi SILC client
3163 to take the debug string as argument. Affected files
3164 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3166 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3168 * Added silc_hash_babbleprint to create a Bubble Babble
3169 Encoded fingerprint. The encoding is developed by Antti
3170 Huima (draft-huima-babble-01.txt), and it creates human
3171 readable strings out of binary data. Affected file
3172 lib/silccrypt/silchash.[ch].
3174 * Print the babble print now in addition of fingerprint as well
3175 in Irssi SILC client. Affected files are
3176 irssi/src/fe-common/silc/module-formats.[ch],
3177 irssi/src/fe-common/silc/core/client_ops.c.
3179 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3181 * Fixed a security problem found in SKE. The initiator's
3182 public key too is now added to the HASH hash value creation
3183 which is signed by the responder to create the SIGN value.
3184 This will prevent anyone in the middle to lie to the responder
3185 about the initiator's public key. If this is done now, the
3186 man in the middle will get caught. Updated the protocol
3189 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Better installation directory handling. Configure module
3192 paths and other paths automatically to example_silc* files
3193 in doc/. A patch by toma.
3195 * Fixed compiler warning from MPI library, and from SILC RNG.
3198 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3199 It can be configured with ./configure. A patch by toma.
3201 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Find correct make to use in prepare-clean. A patch by
3204 toma. Affected file prepare-clean.
3206 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3208 * Added irssi variables use_auto_addr, auto_bind_ip,
3209 auto_bind_port and auto_public_ip.
3211 * Changed the interface for silc_client_send_key_agreement
3212 in lib/silcclient/silcapi.h
3216 irssi/src/silc/core/silc-core.c
3218 lib/silcclient/silcapi.h

3220 lib/silcclient/client_keyagr.c
3223 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3225 * Added silc_pkcs_public_key_compare to compare two
3226 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3228 * Check that the client who set the founder mode on the
3229 channel is the same client that is giving the founder
3230 mode to itself. It is done by comparing the saved public
3231 key (it is saved even in the authentication is passphrase).
3232 Affected file silcd/command.c.
3234 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3237 Affected file lib/silccore/silcpacket.c.
3239 * Process the DISCONNECT packet through scheduler in the
3240 client library. Affected file lib/silcclient/client.c.
3242 * Fixed the silc_client_packet_parse to not to increase
3243 the packet sequence number if the conn->sock and the
3244 current socket connection is not same. This can happen
3245 for example during key agreement when the conn includes
3246 multiple socket connections (listeners). Affected file
3247 lib/silcclient/client.c.
3249 * The sender of the file transfer request now provides also
3250 the pointer (listener) for the key exchange protocol. If
3251 the listener cannot be created then it sends empty key
3252 agreement and lets the receiver provide the listener.
3254 Added `local_ip' and `local_port' arguments to the
3255 silc_client_file_send. If they are provided they are used,
3256 if not then it will attempt to find local IP address, if
3257 not found or bind fails then the remote client will provide
3260 Affected files are lib/silcclient/client_ftp.c and
3261 lib/silcclient/silcapi.h.
3263 * Extended the FILE SEND command to support defining the
3264 local IP and port for key exchange listener. They are
3265 optional. Affected file irssi/src/silc/core/silc-servers.c.
3267 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Defined to WHOIS command reply the sending of fingerprint
3270 of the client's public key (if the proof of posession of the
3271 corresponding private key is verified by the server).
3272 Updated to the protocol specification.
3274 * Added support of receiving the client's public key's
3275 fingerprint in command reply in client library. Affected
3276 file is lib/silcclient/command_reply.c, and
3277 lib/silcclient/idlist.[ch].
3279 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3281 * Do not send over 128 chars long nickname to the server
3282 in NICK command. Affected file lib/silcclient/command.c.
3284 * Do not send over 256 chars long channel names to the server
3285 in JOIN command. Affected file lib/silcclient/command.c.
3287 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Assure that silc_server_close_connection cannot be called
3290 twice for same socket context. Affected file is
3293 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3295 * Send error message to application if opening file for
3296 writing during file transfer fails. Affected file is
3297 lib/silcclient/client_ftp.c.
3299 Remove all file transfer sessions for a client that we're
3300 removing from ID cache.
3302 Affected file is lib/silcclient/client_ftp.c.
3304 * Fixed silc_net_addr2bin to return correct address. Affected
3305 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3307 * Fixed file transfer session removing on signoff notify.
3308 Affected file irssi/src/silc/core/silc-servers.c.
3310 * Added the SilcClientFileError to be returned in the monitor
3311 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3312 Affected file lib/silcclient/silcapi.h.
3314 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * Fixed a crash in silc_client_ftp_free_sessions and
3317 silc_client_ftp_session_free_client. Affected file
3318 lib/silcclient/client_ftp.c.

3332 client library. Affected file lib/silcclient/client_prvmsg.c.
3334 * Do not actually remove the client directly from ID cache
3335 during SERVER_SIGNOFF, but invalidate it. This way we
3336 preserve the WHOWAS info for the client. Affected file
3337 silcd/server_util.c.
3339 * Fixed SERVER_SIGNOFF notify handling in the server. The
3340 server is now able to process incoming SERVER_SIGNOFF notify
3341 for a server that it doesn't even know about. It will remove
3342 the clients provided in the notify. Affected file
3343 silcd/packet_receive.c.
3345 * Check for partial packet in data queue after every packet that
3346 was found from the queue. Return and wait for more data if
3347 there is partial data in queue. Affected file is
3348 lib/silccore/silcpacket.c.
3350 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Added SilcClietFileError enum to indicate error in
3353 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3354 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3355 Affected files lib/silcclient/silcapi.h and
3356 lib/silcclient/client_ftp.c.
3358 * Check that newsize in silc_buffer_realloc is larger than
3359 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3361 * Added better monitor of file transfers. It now monitors
3362 key agreement protocol during the file transfer too. Added
3363 error reporting too. Affected files
3364 irssi/src/silc/core/silc-servers.c,
3365 irssi/src/fe-common/silc/module-formats.[ch].
3367 * Wrote a help file for FILE command.
3369 * Added silc_rng_global_get_byte_fast to get not-so-secure
3370 random data as fast as possible. Random data is read from
3371 /dev/urandom if available and from the SILC RNG if not
3372 available. It is used in padding generation. Affected file
3373 lib/silccrypt/silcrng.[ch].
3375 * All packets in client library are now processed synchronously.
3376 Optimized packet processing a lot. Affected file
3377 lib/silcclient/client.c.
3379 * All server connection packets are processing synchronously
3380 now in server, to optimize packet processing. Affected file
3383 * Include files are installed now only in Toolkit distribution
3384 if make install is given. Affected files: all Makefile.am's.
3386 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Assure that silc_client_notify_by_server_resolve does not
3389 resolve the client information multiple times. If it cannot
3390 be found by the first it cannot be found at all. Affected
3391 file lib/silcclient/client_notify.c.
3393 * Fixed WHOWAS command reply calling. Affected file
3394 lib/silcclient/command_reply.c.
3396 * Removed all references to silc_idlist_get_client from the
3397 Irssi SILC client since that call is internal call used by
3398 the library. The Irssi SILC client will use now client
3399 retrieval functions found in silcapi.h.
3401 * Fixed a bug in resolving nickname info before sending
3402 private message. It used freed memory. Affected file
3403 irssi/src/silc/core/silc-servers.c.
3405 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Assure my_channels statistics cannot go negative in server.
3408 Affected files silcd/server.c, silcd/server_util.c.
3410 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3424 * Added silc_net_localip to return local host's IP address.
3425 Affected file lib/silcutil/silcnet.[ch].
3427 * If key exchange or rekey protocol is active for a connection
3428 parse all packets syncronously since there might be packets
3429 in packet queue that we are not able to process without first
3430 processing packets before them. Affected file silcd/server,
3431 lib/silcclient/client.c.
3433 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3434 whether library should continue processing the packet.
3435 Affected file lib/silccore/silcpacket.h.
3437 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3438 SilcSFTPMonitorData to SFTP server to monitor various
3439 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

3476 file irssi/src/silc/core/silc-channels.c.
3478 * Added SilcClientStatus field to the SilcClientEntry in the
3479 lib/silcclient/idlist.h.
3481 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3482 is incomplete and is being resolved, it won't be resolved
3485 Make sure also that USERS command reply does not resolve
3486 twice information. Affected file is
3487 lib/silcclient/command_reply.c.
3489 Make sure that silc_client_get_clients_by_list does not
3490 resolve twice same information.
3492 * Check for valid client->id in the silc_server_free_client_data.
3493 Affected file silcd/server.c.
3495 * Fixed /GETKEY nick@server not to crash if the server entry
3496 is not found. Affected file lib/silcclient/command.c.
3498 * Fixed the silc_server_check_cmode_rights to check the
3499 requested modes correctly. Affected file silcd/command.c.
3501 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3503 * Better checks for non-printable chars in nick added.
3504 Affected file silcd/command.c.
3506 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Call the silc_server_udpate_servers_by_server in the
3509 primary router that comes back online in the backup resuming
3510 protocol. Otherwise it routes packets wrong. Affected file
3511 silcd/server_util.[ch], silcd/server_backup.c.
3513 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3516 lib/silcutil/silcbuffmt.[ch].
3518 * Redefined the SILC packet header to include the padding
3519 length. Affected file lib/silccore/silcpacket.[ch].
3521 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3522 length for maximum padding up to 128 bytes). Affected
3523 file lib/silccore/silcpacket.h.
3525 * Removed all backwards support for old 0.5.x MAC thingies.
3526 The SILC packet header change makes it impossible to be
3527 backwards compatible.
3529 * Send the ENDING packet with timeout in the backup resuming
3530 protocol. This is to assure that all routers has connected
3531 to the primary router. Affected file silcd/server_backup.c.
3533 * Changed the RNG to take the first IV from random data. It
3534 used to take it from zero actually. Changed the RNG also
3535 to use /dev/urandom during session. /dev/random is used
3536 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3538 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Changed the SILC packet header to have the first two bytes
3541 (the packet length) encrypted. Affected files aroung the
3542 code tree, lib/silccore/silcpacket.[ch]. Removed the
3543 SilcPacketCheckDecrypt callback. It is not needed anymore
3544 since the silc_packet_receive_process will determine now
3545 whether the packet is normal or special.
3547 * Implemented the unidirectional MAC keys. Affected files
3548 lib/silcske/silcske.c, silcd/protocol.c and
3549 lib/silcclient/protocol.c.
3551 * Implemented the packet sequence number to the MAC computation.

3556 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3558 * Allow backup router to announce servers. All servers
3559 announced by backup router are added to the global list
3560 automatically. Update hte server's socket to our primary
3561 router also when backup router announces a server.
3562 Affected file silcd/packet_receive.c.
3564 * Do not update the client->router in the function
3565 silc_server_udpate_clients_by_server if the client is on
3566 global list. We might fail to find any specific server
3567 for locally connected clients and local cell clients. They
3568 should still use the `from' and not `to' as client->router.
3569 This fixes backup router resuming protocol. Affected file
3570 silcd/server_util.c.
3572 * Decrease channel statistics count only if the channel
3573 deletion worked. Affected files are silcd/server.c and
3574 silcd/server_util.c.
3576 * Added silc_server_update_servers_by_server to update origin
3577 of all server entries. Used during backup router protocol.
3578 Affected files silcd/server_util.[ch], silcd/server.c. and
3579 silcd/backup_router.c.
3581 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3582 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3583 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3584 lib/silccrypt/silchmac.c.
3586 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3588 * Assure that router cannot reroute the same channel message
3589 to the sender. Affected file silcd/packet_receive.c.
3591 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * Made better checks that the channel message is not sent
3594 to the router it came from. Affected file is
3595 silcd/packet_send.c. Fixed memory leak too.
3597 * Announce informations for incoming router connection, but
3598 only after checking if it is replaced by backup router.
3599 Affected file silcd/packet_receive.c.
3601 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Fixed the backup resuming protocol to work in multiple
3604 router environment. Affected file silcd/server_backup.c.
3606 * Route packet only to one router in the function
3607 silc_server_packet_send_to_channel. Affected file is
3608 silcd/packet_send.c.
3610 * Fixed silc_server_send_notify_dest to set the broadcast
3611 flag. Fixed the silc_server_send_notify_topic to actually
3612 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3613 Affected file silcd/packet_send.c.
3615 * Changed the SFTP Filesystem interface. Changed the
3616 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3617 the filesystem operation function. The SilcSFTPFilesystem
3618 is now a context that is allocated by all filesystem allocation
3619 functions and it already includes the operations structure
3620 and filesystem specific context. It is given as argument
3621 now to the silc_sftp_server_start. This made the interface
3622 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3623 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3625 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3627 * Changed the backup router adding and getting interfaces
3628 in the server. The router that will be replaced by the
3629 specified backup router is now sent as argument. Affected
3630 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3633 * Added silc_net_addr2bin_ne to return the binary form of
3634 the IP address in network byte order. Affected files
3635 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3637 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * Check for existing server ID in silc_server_new_server
3640 and in silc_server_connect_to_router_final and remove the
3641 old entry if it exists. Affected file silcd/packet_receive.c,
3644 * Send the channel message always to only one router, either
3645 in upstream or downstream. Affected file is
3646 silcd/packet_send.c.
3648 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3650 * Wrote the definition of the backup resuming protocol to the
3651 protocol specification.
3653 * Removed one redundant channel key generation from normal
3654 server during joining procedure. Removed one redundant
3655 channel key sending from server to router during joining
3656 procedure. Affected file silcd/command.c.
3658 * Made minor bugfixes to the backup router resuming protocol.
3659 Affected file silcd/server_backup.c, server.c.
3661 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3663 * Added --disable-asm configuration option. Affected files
3664 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3667 * Implemented the backup resuming protocol that is used to
3668 resume the primary router position in the cell after the
3669 primary router comes back online. Affected files
3670 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3671 and silcd/server_util.[ch].
3673 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Sleep two (2) seconds after sending QUIT command to server.
3676 Affected file lib/silcclient/command.c.
3678 * Assure that if outgoing data buffer is pending do not force
3679 send any data. Affected file silcd/packet_send.c.
3681 * Assure that if outgoing data buffer is pending do not force
3682 send any data. Affected file lib/silcclient/client.c.
3684 * Implemented the backup router support when the primary router
3685 goes down. The servers and routers can now use the backup
3686 router as new primary router without loosing connectivity.
3688 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3690 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3691 in the server to indicate disabled entry. All data read
3692 from the connection will be ignored and no data is sent
3693 for entry that is disabled. Affected files are
3694 silcd/idlist.h, silcd/server.c.
3696 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3698 * Created SFTP client and server test programs in the
3699 lib/silcsftp/tests directory.
3701 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3703 * Implemented memory filesystem (virtual filesystem) for
3704 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3707 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3709 * Implemented the SFTP (SSH File Transfer Protocol) to the
3710 lib/silcsftp. It includes SFTP client and SFTP server
3713 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3715 * Moved lib/silccore/silcprotocol.[ch] to the
3716 lib/silcutil library.
3718 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3719 take variable argument list pointer as argument. Affected
3720 file lib/silcutil/silcbuffmt.[ch].
3722 * Added silc_buffer_set function that is used to set data
3723 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3724 Affected file lib/silcutil/silcbuffer.h.
3726 * Changed various routines in the core library to use the new
3727 silc_buffer_set instead of allocating new buffer only for
3730 * Added 64-bit value formatting and unformatting support to the
3731 silc_buffer_[un]format routines. Affected file is
3732 lib/silcutil/silcbuffmt.[ch].
3734 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3735 to includes/bitmove.h.
3737 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3739 * Fixed channel user mode saving in client library. Affected
3740 file lib/silcclient/command[_reply].c.
3742 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3744 * Defined the file transfer to the SILC Protocol. Added
3745 new packet type SILC_PACKET_FTP and defined File Transfer
3746 Payload. The mandatory file transfer protocol is SFTP
3747 (SSH File Transfer Protocol). Affected file in addition
3748 of the internet draft is lib/silccore/silcpacket.h.
3750 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3751 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3752 is used as part of backup router protocol when the primary
3753 router of the cell is back online and wishes to resume
3754 the position as primary router.
3756 * Redefined the MAC generation keys in the protocol. The
3757 same key is not used anymore in both direction. Both
3758 direction will now use different keys for sending and
3759 receiving. This fixes a potential security flaw. This
3760 change causes incompatibilities in the protocol.
3762 * Redefined also the MAC computation from the packet.
3763 An packet sequence number is now added to the MAC
3764 computation. This prevents possible replay attacks against
3765 the protocol. This change too causes incompatibilities
3768 Added `sequence' field to the SilcPacketContext to hold
3769 the current sequence number for the packet.
3771 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3773 * Added `created' field to the SilcIDListData in the file
3774 silcd/idlist.h to indicate the time when the entry was
3777 * Added `created' field to the SilcChannelEntry too. Affected
3778 file silcd/idlist.h.
3780 * Added `creation_time' aguments to all the announcement functions
3781 in the server. If it is provided then only the entries that
3782 was created after the provided time frame are actually
3783 announced. Affected file silcd/server.[ch].
3785 * The protocol says that the Channel ID's IP address must be
3786 based on the router's IP address. Added check for this in
3787 the silc_server_new_channel when processing incoming New Channel
3788 Payload. Affected file silcd/packet_receive.c.
3790 * Print out the correct version with --version in SILC client.
3791 Affected file irssi/src/silc/core/silc-core.c.
3793 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3795 * Fixed WHOWAS command to check for completnes of the client
3796 entry always, not just when the command is coming from client.
3797 Affected file silcd/command.c.
3799 * Added new function silc_server_packet_queue_purge to purge the
3800 outgoing data queue to the network. After the function returns
3801 it is guaranteed that the outgoing packet queue is empty.
3802 Affected file silcd/packet_send.[ch].
3804 * Purge the outgoing packet queue in the rekey protocol's final
3805 callback to assure that all rekey packets go to the network
3806 before quitting the protocol. Affected file silcd/server.c.
3808 * Added silc_client_packet_queue_parse as similar function as
3809 in server to the client library. The affected file is
3810 lib/silcclient/client.c.
3812 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3814 * Splitted silcd/server.c and created silcd/server_util.[ch]
3815 for utility functions.
3817 * Added new socket flag SILC_SF_DISABLED to indicate that the
3818 connection is open but nothing can be sent to or received from
3819 the connection. Affected file lib/silcutil/silsockconn.[ch].
3820 The checking for disabled socket is checked in the low level
3821 silc_socket_write and silc_socket_read functions.
3823 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3825 * Allow only nicknames and channel names that fits into the
3826 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3828 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * When processing JOIN command reply in server check that if
3831 the channel exists in our global list we'll move it the local
3832 list. Affected file silcd/command_reply.c.
3834 * Fixed the check whether client is joined on the channel already
3835 in JOIN command. Affected file lib/silcclient/command.c.
3837 * Fixed the JOIN command reply to check whether the channel
3838 already exists. Affected file lib/silcclient/command_reply.c.
3840 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3842 * Added silc_ske_status_string to map the SKE error numbers
3843 to readable strings. The affected files are
3844 lib/silcske/silcske[_status].[ch].
3846 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3848 * Do not show the private channels on the WHOIS channel list
3849 as it is not allowed by the protocol. The affected file is
3852 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3854 * Assure that the packet length digged from the actual packet
3855 is something sensible in the silc_packet_decrypt_rest_special
3856 in lib/silccrypt/silcpacket.c.
3858 * Free and NULL the allocated pointer in silc_hmac_alloc if
3859 the HMAC allocation fails. The affected file is
3860 lib/silccrypt/silchmac.c.
3862 * Print the selected security properties to the log files in
3863 the server. Affected file silcd/protocol.c.
3865 * Add SKE's reference counter even if calling the completion
3866 callback manually. Otherwise it goes negative, although it
3867 does not cause any problems. The affected file is
3868 lib/silcske/silcske.c.
3870 * Remove the client entry with short timeout after giving the
3871 KILL command. Affected file lib/silcclient/command.c.
3873 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3874 case all found clients are already disconnected (WHOWAS would
3875 found them) in the server. Affected file silcd/command.c.
3877 * Update the last_receive (time of last data received) to be
3878 updated only when received private or channel message so that
3879 the idle time showed in WHOIS makes more sense.
3881 * Added boolean field `valid' in to the SilcClientEntry in the
3882 client library to indicate whether the entry is valid or not.
3883 This fixes the nickname change bug on channel when changing
3884 the nickname to be same than the old (like nick to Nick) the
3885 nickname formatter doesn't set the new nick anymore to Nick@host.
3886 Affected file lib/silcclient/idlist.[ch].
3888 * Now actually fixed the nickname changing on disconnection.
3889 Added new function silc_change_nick to the Irssi SILC Client.
3890 Affected file irssi/src/silc/core/client_ops.c,
3891 irssi/src/silc/core/silc-nicklist.[ch].
3893 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Check that the public key exists in the GETKEY command before
3896 trying to encode it. Affected file silcd/command.c.
3898 * Print some notifications on received public keys with GETKEY
3899 command in the Irssi SILC Client. Affected files are
3900 irssi/src/fe-common/silc/module-formats.[ch],
3901 irssi/src/silc/core/client_ops.c.
3903 * Use IDENTIFY command to resolve the server information in the
3904 GETKEY command instead of INFO command. Affected file
3905 lib/silcclient/command.c.
3907 * All command reply functions in the client library now calls
3908 the pending command reply callbacks even if an error has
3909 occurred. The server has done this a long time and now it was
3910 time to move the client library to this as well. Now all
3911 errors can be delivered back to the pending command reply
3912 callbacks if necessary. Affected files are
3913 lib/silcclient/command[_reply].[ch].
3915 * Change the nickname on disconnection back to the username
3916 because in reconnect the server will enforce it to it anyway.
3917 Affected file irssi/src/silc/core/silc-servers.c.
3919 * Fixed a config file parsing bug in the Irssi SILC client.
3920 Affected file irssi/src/silc/core/clientconfig.c.
3922 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3924 * When printing the channel mode on JOIN, verify that the
3925 channel key and channel's HMAC are valid. Affected file
3926 irssi/src/silc/core/client_ops.c.
3928 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3930 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3931 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3932 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3934 * Removed channel key rekey task deleting from the function
3935 silc_server_save_channel_key. Affected file silcd/server.c.
3936 Added explicit timeout task context instead that is used to
3937 delete the task if we are registering a new task before the
3938 new task has elapsed.
3940 * When channel key rekey occurs the client library now saves
3941 the old channel key for a short period of time (10 seconds) and
3942 is able to use it in case some is still sending channel
3943 messages encrypted with the old key after the rekey. Affected
3944 file lib/silcclient/[idlist.h|client_channel.c].
3946 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Added check to the silc_server_new_id_real to not accept
3949 new ID if it is the sender's own ID. Affected file is
3950 silcd/packet_receive.c.
3952 * Assure that we do not announce ourself or the one we've
3953 sending our announcements when we're router and are announcing
3954 servers to our primary router. Affected file silcd/server.c.
3956 * Fixed silc_server_command_identify_check_client to assemble
3957 correct WHOIS packet. It send corrupted WHOIS packet and
3958 caused problem with router to router connections. Affected
3959 file silcd/command.c.
3961 Fixed also silc_server_command_whois_check the same way
3962 as for the IDENTIFY command.
3964 * Added new SilcIDListStatus to the server in the SilcIDListData
3965 structure. The status now includes the current status of
3966 the entry (like registered, resolved etc.). Affected file
3967 silcd/idlist.[ch]. Defined a bunch of different status types
3968 as well. This replaced the old boolean registered field as well.
3970 Added resolve_cmd_ident field to the SilcClientEntry structure
3971 too so that if the entry is for example being resolved so
3972 another command may attach to the same pending command reply
3973 without requiring to resolve the same entry again. This concept
3974 should optimize the WHOIS and the IDENTIFY resolving under
3975 heavy load by taking away unnecessary resolving for entries
3976 that are being resolved already.
3978 Added support for adding multiple pending commands for one
3979 command idenfier. Affected file silcd/command[_reply].[ch].
3981 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3982 before deleting the data. Otherwise the hash table will have
3983 freed data in comparison functions. Affected file is
3984 silcd/command_reply.c.
3986 * Fixed silc_idlist_replace_client_id to add the new entry to
3987 the cache with NULL nickname. Otherwise there will be invalid
3988 memory as the nickname after the nickname is freed. Affected
3989 file silcd/packet_receive.c.
3991 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3992 saved into wrong slots because the previous number of entries
3993 was not taken into account. Affected file silcd/idlist.c.
3994 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3996 * If we are router and we receive JOIN notify to a channel that
3997 does not have any users then notified client is marked as the
3998 channel founder, as it is it. The affected file is
3999 silcd/packet_receive.c
4001 * Added to the extended hash table API's table_del_*ext functions
4002 the destructor as argument too, so that the caller can decide
4003 which destructor to use or whether to use destructor at all.
4004 Affected file lib/silcutil/silchashtable.[ch].
4006 * Fixed ID Cache purging. It actually deleted the entries from
4007 the hash table after the data was freed. The hash table ended
4008 up comparing freed memory. The affected file is
4009 lib/silccore/silcidcache.c.
4011 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * Fixed Irssi SILC client's KILL command's HELP syntax.
4015 * The USERS command now resolves the detailed user information
4016 if the userinfo field is missing. Affected file is
4017 lib/silcclient/command_reply.c.
4019 * Do not print error in silc_file_read if the read file does
4020 not exist. Just silently return NULL. Affected file is
4021 lib/silcutil/silcutil.c.
4023 * Fixed the silc_log_output to not wine about NULL filename
4024 and to not create some bogus " " filename. Affected file is
4025 lib/silcutil/silclog.c.
4027 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4029 * Fixed various printing bugs on the user interface in the
4030 Irssi SILC Client. Minor changes that were forgotten from
4033 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Fixed the configure.in.pre and the compilation and distribution
4036 environment to support the new autoconf 2.52. That version is
4037 now required to compile the CVS trunk.
4039 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4041 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4042 to generally parse user@fqdn format strings. Affected file
4043 lib/silcutil/silcutil.c.
4045 * Added nickname_format and nickname_force_format fields to the
4046 SilcClientParams structure. The first one defines the format
4047 for the nicknames that the library will enforce if the receives
4048 multiple same nicknames. The second one is boolean value and
4049 can be used to force the library to always enforce the format
4050 to the nicknames regardles whether there are multiple nicknames
4051 or not. This configurable formatting was employed to flexibly
4052 support accessing multiple nicknames from the user interface.
4053 The userinterface can now set the nicknames to what ever format
4054 they prefer. Affected file lib/silcclient/silcapi.h.
4056 Added function silc_client_nickname_format to the file
4057 lib/silcclient/idlist.c. It performs the nickname formatting.
4059 Added new field `hostname´ to the SilcClientEntry context.
4060 It holds the hostname of the client. Affected file is
4061 lib/silcclient/idlist.h.
4063 * Irssi SILC Client sets the nicknames in nick@hostn format.
4064 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4065 irssi/src/silc/core/silc-core.c.
4067 The WHOIS printing now also shows both the real nickname and
4068 the formatted nickname so that user knows how to access the
4069 user if there are multiple same nicknames cached. Affected
4070 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4071 printing formatting too to take the hostname now as a separate
4072 argument. The Affected file is
4073 irssi/src/fe-common/silc/modules-formats.[ch].
4075 * Changed the silc_client_get_clients_local to accept the formatted
4076 nickname as argument. It accepts the real nickname too but the
4077 formatted nickname can be used to find the true entry from
4078 multiple entries. Affected file lib/silcclient/silcapi.h and
4079 lib/silcclient/idlist.c.
4081 * Added nickname_format_parse field to the SilcClientParams.
4082 It is a callback function provided by the application to parse
4083 the nickname out of the formatted nickname string. The library
4084 calls it to get the nickname from the formatted string. Since
4085 the application generally knows better the format of the nickname
4086 string it parses it instead of the library, even though library
4087 encodes the formatted string. If the callback function is not
4088 provided then the library will use the string as is. The
4089 affected file is lib/silcclient/silcapi.h.
4091 * All the nickname strings passed to the client library in
4092 commands are now expected to be formatted nickname strings.
4093 If the command does not support the formatted nickname string
4094 it will assume that the sent string is the actual nickname.
4095 Affected file lib/silcclient/command.c.
4097 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4099 * Added public key authentication support to OPER and SILCOPER
4100 commands in the client library. Affected file is
4101 lib/silcclient/command.c.
4103 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4105 * Changed the get_auth_methdod client operation to be asynchronous.
4106 It can be async if the application resolves the authentication
4107 method from the server during the negotiation. Added new
4108 SilcGetAuthMeth completion callback that the application will
4109 call after resolving the authentication method.
4111 Added function silc_client_request_authentication_method that
4112 the application can use to resolve the authentication method
4113 from the server. Added also SilcConnectionAuthRequest callback
4114 that the library will call after the server has replied. The
4115 application can call this function if it does not know the
4116 current authentication method.
4118 Affected files are lib/silcclient/client.c and
4119 lib/silcclient/silcapi.h.
4121 * The Irssi SILC client now automatically resolves the authentication
4122 method incase any configuration information is not present (and
4123 currently there never is). The affected file is
4124 irssi/src/silc/core/client_ops.c.
4126 * Fixed public key authentication from the client library.
4127 Affected file lib/silcclient/protocol.c. Changed also the
4128 protocol specification about the public key authentication in
4129 the connection authentication protocol. The actual data to be
4130 signed is now computed with a hash function before signing.
4132 * Fixed the public key authentication from the server as well.
4133 Affected file silcd/protocol.c.
4135 * Removed the mlock()'s from the memory allocation routines.
4136 Affected file lib/silcutil/silcmemory.c. The ./configure does
4137 not check anymore for the mlock(). Affected file is
4140 * Fixed USERS command in server to allow the execution of the
4141 command for private and secret channels if the client sending
4142 the command is on the channel. Affected file silcd/command.c.
4144 * Fixed silc_client_get_clients_local to return the clients
4145 count correctly. It could return wrong value. Affected file
4146 lib/silcclient/idlist.c.
4148 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4150 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4151 types. The assembler optimizations seemed not to like 64-bit
4152 data types. The assmebler optimizations thus are now enabled
4153 also for BSD systems as opposed to only enable them for Linux.
4155 * Do not check for threads at all on BSD systems. Affected
4156 file configure.in.pre.
4158 * Removed -n and -h options from the Irssi SILC Client since
4159 they are not used in silc.
4161 * Fixed the prime generation to assure that the first digit
4162 of the generated random number is not zero since our conversion
4163 routines does not like number strings that starts with zero
4164 digit. If zero digit is seen the random number is regenerated.
4165 This caused some corrupted RSA keys when the zero first digit
4166 was met. Affected file lib/silcmath/silcprimegen.c.
4168 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Fixed WIN32 configuration in the ./configure script.
4171 Fixed to include xti.h on environments that has it.
4172 Patches by Carsten Ilchmann and andrew.
4174 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * Changed the silc_id_create_client_id to be collision
4177 resistant. It is now assured that there cannot be created
4178 two same client ID's. I suspect that some weird bugs in
4179 the server were actually caused by duplicate Client IDs.
4180 Affected file silcd/serverid.[ch]. A router receiving
4181 new ID now also assures and informs the sending server
4182 if the ID caused collision.
4184 * Changed the silc_id_create_channel_id to also assure that
4185 there are no collisions.
4187 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4189 * Statement about ignoring the Mutual Authentication flag when
4190 performing rekey with PFS was a bit misleading. It is ignored
4191 if it was set in the initial negotiation, it cannot be even
4192 set in the rekey. Fixed in the ke-auth draft. Started the
4193 new versions of the protocol drafts in the doc/.
4195 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4197 * Fixed a bug in silc_client_command_identify_save when saving
4198 new channel information. The channel name was no duplicated
4199 and caused crash on exit. Affected file is
4200 lib/silcclient/command_reply.c.
4202 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4204 * Fixed the getkey command handling in the server. Send just
4205 empty OK reply to the sender if the key could not be fetched
4206 (but everything else was ok, like the key just was not available).
4207 Changed the public key parameter to optional in the protocol
4208 specs so that empty OK reply can be sent. Affected file
4211 Added a message to Irssi SILC client to tell to user if the
4212 server did not return a public key.
4214 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4216 * Fixed a channel key regeneration bug. It registered new
4217 timeout tasks exponentially until all system resources were
4218 used. Affected file silcd/server.c.
4220 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4222 * Added the SILC Document generator to the scripts/silcdoc.
4223 It can be used to generate the Toolkit Reference Manual out
4224 of the source tree. Internally it will also use the RoboDoc
4225 generator now imported in util/robodoc.
4227 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4229 * Added couple of return's in rekey protocol if error orccurred
4230 during the protocol. The execution must be terminated.
4231 Affected file silcd/protocol.c. Also, terminate the protocol
4232 always with timeout.
4234 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4236 * The client's Client ID was created initally from the wrong
4237 nickname (it could have been in format nick@host) in the
4238 silc_server_new_client. Affected file silcd/packet_receive.c
4240 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4242 * Added some SILC_LOG_ERROR's to various error conditions
4243 if client could not be added to ID cache. Affected files
4244 silcd/packet_receive.c and silcd/server.c.
4246 * When client's sock->user_data is freed, NULL also the
4247 client->router and client->connection pointers. Added check
4248 for these pointers being NULL to various places around the
4249 code. Affected file silcd/server.c.
4251 * Added client->data.registered == TRUE checks to various
4252 places around the code to assure that unregistered client's
4253 are not handled when it is not allowed. Affected file
4256 * Added `bool registered' fields to all
4257 silc_idlist_[server|client]_get_* routines to indicate whether
4258 the fetched client needs to be registered or not. Affected
4259 file silcd/idlist.[ch].
4261 * Add your own entry as registered to the ID cache in the
4262 server. Affected file server.c.
4264 * Fixed a bug in silc_server_new_server. The SilcServer was
4265 set as the new server's context instead of SilcServerEntry.
4266 This naturally caused some weird bugs.
4268 * Added "updated" field the SilcChannelEntry which indicates
4269 the time since the channel entry was last accessed. This
4270 can be used to determine whether it is necessary to
4271 announce the channel after backup resuming protocol.
4272 Affected files silcd/idlist.[ch].
4274 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4276 * Do not delete the channel rekey task when adding it
4277 for in silc_server_create_channel_key.
4279 * Changed the silc_server_create_channel_key to return
4280 TRUE or FALSE to indicate the success of the channel key
4283 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4285 * Fixed MSVC++ project files and added missing files to
4286 Makefiles under win32/.
4288 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4290 * Do not add TCP_NODELAY flag if the operating system
4291 does not have it defined. Affected files are
4292 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4294 * Fixed buffer overflow from Irssi SILC Client. Affected
4295 file irssi/src/fe-common/core/themes.c.
4297 * Fixed double free in client library in the file
4298 lib/silcclient/client.c when disconnecting from server.
4300 * Applied double free patch from cras to Irssi SILC client.
4301 Affected files irssi/src/core/[modules/expandos].c
4303 * Fixed the disconnection handling to Irssi SILC Client.
4304 The application must call silc_client_close_connection
4305 in ops->connect client operation in case of failure of
4306 the connection. Affected file is
4307 irssi/src/silc/core/client_ops.c.
4309 * Do not set sock->protocol to NULL in the function
4310 silc_client_close_connection after executing the protocol's
4311 final callback since the sock might not be valid anymore.
4312 Affected file lib/silcclient/client.c.
4314 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4316 * Do not enable SILC_THREADS if the linking with libpthread
4317 did not happen. Affected file configure.in.pre.
4319 * Added notion to protocol specification that server must
4320 verify the sent authentication payload with CMODE when
4321 setting the channel founder key. Implemented it to the
4322 server. Affected file silcd/command.c.
4324 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4326 * Added _EXTRA_DIST SILC distribution variable to the
4327 distributions file. It is used to conditionally add extra
4328 files or directories to the specific distribution. Affected
4329 files ./prepare, Makefile.am.pre and distributions.
4331 Removed the `_' from the start of the distribution names.
4334 * Added README.WIN32 for instructions to compile the Toolkit
4337 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Fixed a double free in disconnection in the server. Affected
4340 file is silcd/server.c.
4342 * Fixed the lib/silcske/groups.c to work now also with GMP
4343 MP library. The string conversion did not work when using
4344 specific base and the base is indicated in the string as well.
4346 * Created win32/ directory which now includes MSVC++ specific
4347 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4348 It will appear only in the toolkit distribution
4350 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4352 * Changed the key material distribution function in case when
4353 the hash output is too short. The data is now concatenated
4354 a bit differently than it used to. Made the change to the
4355 SKE protocol specification.
4357 * Added better GMP detection to configure.in.pre. A patch
4360 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4362 * Fixed a minor bug in SKE that might cause some problem on
4363 some platforms. Affected file lib/silcske/silcske.c.
4365 * Added the cookie checking for initiator in the SKE. It checks
4366 that the responder returns the sent cookie unmodified. The
4367 affected file is lib/silcske/silcske.c. Added new SKE
4368 error type INVALID_COOKIE that can be sent during the
4369 negotiation. Fixed some memory leaks as well.
4371 * Added the "invalid cookie" error message to Irssi SILC client's
4374 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * Added `task_max' field to the SilcClientParams to indicate
4377 the maximum tasks the scheduler can handle. If set to zero,
4378 default values are used. Affected file lib/silcclient/silcapi.h.
4380 * Fixed memory leaks in silc_client_close_connection. Affected
4381 file lib/silcclient/client.c.
4383 * Added silc_client_del_client_entry to client library to free
4384 all memory of given client entry. Affected file is
4385 lib/silcclient/idlist.[ch].
4387 * Added new functions silc_client_del_channel and
4388 silc_client_del_server to delete channel and server entries.
4389 Affected file lib/silcclient/[silcapi.h/idlist.c].
4391 * Removed silc_client_del_client_by_id from silcapi.h.
4393 * Fixed the INFO command to return the server's own info
4394 correctly when querying by Server ID. Affected file is
4397 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4399 * Removed the non-blocking settings in WIN32 code in the
4400 silc_sock_[read/write] and added SleepEx instead. Affected
4401 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4402 of input data is now checked with FIONREAD and ioctlsocket.
4404 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4406 * Call silc_schedule_task_del_by_context in the
4407 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4408 Affected file lib/silccore/silcprotocol.c.
4410 * Call silc_protocol_cancel for active protocols in the
4411 silc_server_close_connection if the funtion
4412 silc_server_free_sock_user_data has not been called.
4413 Affected file silcd/server.c.
4415 * Generic tasks cannot be deleted using the del_by_fd
4416 task deleting function since generic tasks does not match
4417 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4419 * Added a notion to SILCOPER help file that the SILCOPER works
4420 only on router server, not on normal server.
4422 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4424 * Added for WIN32 support for the new scheduler as well.
4425 Affected file lib/silcutil/win32/silcwin32schedule.c.
4427 * Fixed the SHA1 implementation to work on various platforms.
4429 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4431 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4432 API. It is part of the scheduler now. Everything else is
4433 as previously but some functions has changed their names.
4434 Checkout the lib/silcutil/silcschedule.h for the interface.
4435 Updated all applications to use the new interface. Affected
4436 files are lib/silcutil/silcschedule.[ch].
4438 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4440 * Found a bug in the SKE implementation. The HASH value,
4441 specified by the protocol, was not computed correctly. The
4442 public key of the responder was not added to the computation
4443 even though it is mandatory. Affected file lib/silcske/silcske.c.
4444 This unfortunately causes incompatibilities with older
4445 clients and servers.
4447 * Added WIN32 specific network init and uninit functions:
4448 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4449 the Winsock2. Affected file lib/silcutil/silcnet.h and
4450 lib/silcutil/win32/silcwin32net.c.
4452 * Set the socket always to nonblocking mode on WIN32 after
4453 reading data or writing data. Affected file is
4454 lib/silcutil/win32/silcwin32sockconn.c.
4456 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4458 * Fixed various compilation problems under WIN32. Affected
4459 files lib/silcutil/win32/silcwin32thread.c and
4460 lib/silcutil/win32/silcwin32schedule.c.
4462 * Removed all _internal.h #includes from public header
4463 files. Internal headers must never be included from
4466 Removed also the lib/silcske/payload_internal.h file.
4468 * All include files that may be needed (public and some others
4469 included by the public headers) by application developers are
4470 now copied to the ./includes directory. It does not copy any
4471 internal headers. Affected file Makefile.defines.pre and all
4472 Makefile.am's under lib/ and subdirs.
4474 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4476 * Do not change the ~/.silc directory's permissions automatically.
4477 Affected file irssi/src/silc/core/clientutil.c.
4479 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4481 * Do not cancel the protocol in silc_server_close_connection
4482 it might cause recursion. Now cancelled in the function
4483 silc_server_free_sock_user_data. Affected file silcd/server.c.
4485 * Fixed the silc_server_remove_clients_by_server to regenerate
4486 the channel keys correctly finally. Added also new function
4487 silc_server_remove_clients_channels to actually do it.
4488 Affected file silcd/server.c.
4490 * Fixed the silc_server_new_channel to not crash by giving
4491 wrong router to the new channel. Affected file is
4492 silcd/packet_receive.c.
4494 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4496 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4497 which is given as argument to the silc_client_alloc now.
4498 It can be used to configure the client and set various parameters
4499 that affect the function of the client.
4501 * The USERS command in server did not check whether the channel
4502 is private or secret. Affected file silcd/command.c.
4504 * Added new argument to the USERS command in protocol specification.
4505 The USERS command now can take the channel name as argument
4506 as well. Added support for this in client and server and
4507 updated the protocol specs.
4509 * Completed the GETKEY command in client. It can be now used
4510 to fetch also servers public key not only some clients.
4511 Affected files lib/silcclient/command[_reply].c.
4513 * Added silc_client_get_server to return server entry by the
4514 server name. Affected files lib/silcclient/silcapi.h and
4517 * Redefined the IDENTIFY command in protocol specification to be
4518 more generic. It now can be used to query information about
4519 any entity in the SILC Network, including clients, servers and
4520 channels. The query may be based either the entity's name
4521 or the ID. Added support for this in both client and server.
4523 Affected files silcd/command.c and lib/silcclient/command.c
4524 and command_reply.c.
4526 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4527 the _from_client and _from_server functions. Affected file
4530 * Added silc_client_get_channel_by_id_resolve to the file
4531 lib/silcclient/silcapi.h to resolve channel information by
4532 its ID. Added also silc_client_get_channel_by_id that
4533 does not resolve it from the server.
4535 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4537 * Added SilcServerEntry context into the client library
4538 to represent one server. The INFO command now allocates
4539 these to save the resolved server info. For now on the
4540 client library will also keep information about servers,
4541 connected and resolved with INFO.
4543 The INFO command now allocates the SilcServerEntry context
4544 and saves the server info there. The COMMAND_REPLY in
4545 the INFO now returns the parameters to application in
4546 same order as defined in the protocol specification.
4548 The entries are cached in the client->server_cache.
4550 * The INFO command is now issued after received the Client ID
4551 from the server. Affected file lib/silcclient/client.c.
4553 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4554 to the application as the mode changer might be server.
4555 It is guaranteed that NULL is not returned anymore to the
4556 application. Affected file lib/silcclient/client_notify.c.
4558 The ID Type is now also passed to the application so that
4559 it can check whether the returned entry is SilcClientEntry
4562 Added new function silc_client_get_server_by_id to return
4563 the server entry by ID. Affected files are the
4564 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4566 * Do not create the channel in the Irssi SILC Client when issuing
4567 the JOIN command but when received the sucessful JOIN command
4568 reply. Otherwise the channel might get created even though we
4569 could not join it. The Affected file is
4570 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4572 * Fixed a channel joining bug in router. The router must also
4573 check the channel modes, invite and ban lists etc. when serving
4574 the JOIN command sent by normal server. Affected file is
4575 silcd/command.c. The router now resolves the client's
4576 information from the server who sent the JOIN command if it
4577 does not know it, and processes the JOIN command only after
4580 * Changed the SilcCommandCb to take new argument; void *context2.
4581 Affected file lib/silccore/silccommand.h
4583 The second argument in the command callbacks in the server now
4584 includes the SilcServerCommandReplyContext if the command was
4585 called as pending command callback from the command reply.
4586 Otherwise it is NULL. When called as pending the status of the
4587 command reply will be checked and if it was erronous the
4588 error will be sent to the original sender of the command.
4589 This way the client always receives the error messages even
4590 though the server was actually the one who received the error
4591 when it resent the command to router, for example. Affected
4592 files silcd/command[_reply].[ch].
4594 * Fixed sending WHOWAS command's error message to client if
4595 the requested client could not be found. It was missing.
4598 * Changed the CMODE and CUMODE commands reply arguments in the
4599 protocol specification. The Channel ID is now sent in both
4600 of the commands to identify the channel. Implemented this
4601 new feature to the client and server. Affected files
4602 lib/silcclient/command_reply.c and silcd/command.c.
4604 * Made better checks for invite and ban lists in the JOIN
4605 command in server. Affected file silcd/command.c.
4607 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4609 * The server now performs the incoming host IP/DNS lookup
4610 using the silc_socket_host_lookup and thus does not block
4611 the server anymore. Affected file silcd/server.c.
4613 * Completed the multi-thread support for SILC Scheduler in
4614 the lib/silcutil/silcschedule.c.
4616 * Fixed the configure.in.pre to detect the pthread correctly
4619 * Fixed a deadlock in silc_task_queue_wakeup in the file
4620 lib/silcutil/silctask.c.
4622 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4624 * Added new function silc_schedule_wakeup that is used in
4625 multi-threaded environment to wakeup the main thread's
4626 schduler. It needs to be used when a thread adds a new task
4627 or removes a task from task queues. After waking up, the
4628 scheduler will detect the task queue changes. If threads
4629 support is not compiled in this function has no effect.
4630 Implemented the wakeup mechanism to both Unix and WIN32
4631 systems. Affected files are lib/silcutil/silcschedule.[ch],
4632 lib/silcutil/unix/silcunixschedule.c and the
4633 lib/silcutil/win32/silcwin32schedule.c.
4635 * Added new function silc_task_queue_wakeup to wakeup the
4636 scheduler by the specified task queue. Affected file
4637 lib/silcutil/silctask.[ch].
4639 * The silc_socket_host_lookup_start now wakes up the scheduler
4640 after adding the timeout task. Affected file is
4641 lib/silcutil/silcsockconn.c.
4643 * The silc_socket_host_lookup is synchronous now if the threads
4644 support is not compiled in. However, the callback is still
4645 called asyncronously through the scheduler, anyway. Affected
4646 file lib/silcutil/silcsockconn.c.
4648 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4650 * Added new function silc_socket_host_lookup to perform
4651 asynchronous IP and FQDN lookups for the socket connection.
4652 Affected files lib/silcutil/silcsockconn.[ch].
4654 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4656 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4657 that may or may not compile the mutex support in.
4659 Changed the silc_mutex_alloc interface. It allocates the
4660 mutex now to the sent pointer and returns TRUE or FALSE.
4662 Affected file lib/silcutil/silcmutex.h.
4664 * Wrote the SILC Task Queue interface to support multi-threads.
4665 Affected file lib/silcutil/silctask.[ch].
4667 * Wrote the SILC Scheduler to support multi-threads. Affected
4668 file lib/silcutil/silcschedule.c.
4670 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4672 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4673 in lib/silcutil/win32/.
4675 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4677 * Defined SILC Mutex API and SILC Thread API and implemented
4678 them for Unix. Affected files are
4679 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4680 lib/silcutil/unix/silcunixmutex.c and
4681 lib/silcutil/unix/silcunixthread.c.
4683 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4685 * Fixed the silc_server_remove_clients_by_server's channel
4686 key re-generation. The hash table handling was incorrect
4687 and would not work with many channels. Affected file is
4690 * Fixed some memory leaks around the server code.
4692 * Rewrote the silc_server_get_users_on_channel to support IPv6
4693 based Client ID's. Affected file silcd/server.c.
4695 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4696 specification. However, a separate document must be written
4697 to define the detailed signing procedure and the payload
4698 associated with the flag. Defined the flag to the
4699 lib/silccore/silcchannel.h as well.
4701 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4703 * Changed the dynamic tables to static size tables in the
4704 lib/silccrypt/silchmac.c.
4706 * Removed GCC dependencies from the code. A patch by cras.
4708 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4710 * Do not show the error "Error receiving packet bla bla"
4711 in server if it really was not an error (-2 means that reading
4712 is pending). Affected file silcd/server.c.
4714 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4716 * Fixed a possible crash in silc_server_remove_clients_by_server
4717 in silcd/server.c. Fixed there also some memory leaks.
4719 * Fixed the silc_idlist_replace_client_id. It could replace
4720 wrong key in the hash table. Affected file silcd/idlist.c.
4722 * Do not check whether there are global users on the channel
4723 if the channel->global_users is FALSE. Affected functions
4724 silc_server_remove_from_one_channel and
4725 silc_server_remove_from_channels in silcd/server.c. Also,
4726 do not check if the removed client is local as we can be
4727 sure that global client was not removed from the channel
4728 and checking for global users is not needed.
4730 * The silc_server_remove_clients_by_server now re-generates
4731 the channel keys correctly for those channels that had
4732 clients removed from them. Affected file silcd/server.c.
4734 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4736 * Found the reason of random crashes in the server. We weren't
4737 ignoring the SIGPIPE signal (which can be sent in write())
4738 and it crashed the server. Affected file silcd/silcd.c.
4740 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4742 * Assure that sock->user_data is not NULL in the function
4743 silc_server_packet_send in silcd/packet_send.c.
4745 * Disconnect the remote connection if it could not be added
4746 to any ID lists in the server. The affected file is
4749 * Check in silc_server_packet_send[_real/dest] that the
4750 socket is not disconnecting and ignore the data if it is.
4751 Affected file silcd/packet_send.c.
4753 * Define inline to __inline on native WIN32 compilation.
4754 Affected file includes/silcwin32.h.
4756 * Added some explicit type casts for inline code since MSVC
4757 require them. Affected files lib/silcutil/silcbuffer.h,
4758 lib/trq/silcdlist.h and lib/trq/silclist.h.
4760 * Print warning in log files from now on if the packet
4761 decryption fails. Affected file silcd/server.c.
4763 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4765 * Changed the `say' client operation's interface to accept
4766 new `type' argument to indicate the type of the message sent
4767 by the library. The application may filter the library's
4768 messages according the type. The affected file is the
4769 lib/silcclient/silcapi.h.
4771 * Added two new functions to lib/silcclient/silcapi.h:
4772 silc_client_del_client and silc_client_del_client_by_id.
4773 Affected file lib/silcclient/idlist.c.
4775 * Moved the clientincludes.h from includes/ to silc/ and
4776 serverincludes.h from includes/ to silcd/.
4778 * The modes for the CMODE and CUMODE are now passed as
4779 uint32 for application with COMMAND_REPLY. The affected
4780 file is lib/silcclient/command_reply.c.
4782 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4784 * /WHOIS without arguments shows client's own information.
4785 Affected file lib/silcclient/command.c.
4787 * Changed PING to not accept any arguments. The specs
4788 says that client can ping only the connected server so
4789 requiring an argument is not needed. Affected file is
4790 lib/silcclient/command.c.
4792 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4794 * Fixed a fatal bug in private message sending and reception
4795 encryption and decryption when using private message keys.
4796 The implementation was incorrect and did not follow the
4797 specification. It causd that some of the message were
4798 lost since it did not use the sending and receiving keys
4799 as the protocol suggests. This has been fixed and will cause
4800 incompatibilities with older clients when sending private
4801 message encrypted with private message keys. Affected files
4802 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4803 and various other in Irssi SILC Client.
4805 Added `responder' boolean argument to the functions
4806 silc_client_add_private_message_key[_ske] to indicate when
4807 the key is added as responder or initiator of the key
4810 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4812 * Removed the silc_ske_check_version function and created
4813 a SilcSKECheckVersion callback. Added also a function
4814 silc_ske_set_callbacks that is now used to set all SKE
4815 callbacks. The callback functions are not given to
4816 the SKE functions anymore, but this function is used to
4819 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4821 * Added `silc_version' argument to the silc_client_alloc
4822 to define the version of the application for the library.
4823 The library will use the version string to compare it
4824 against the remote host's (usually a server) version
4825 string. Affected file lib/silcclient/silcapi.h
4827 * Added the KE protocol context to Key Agreement context
4828 in client library so that we can abort the SKE if it
4829 is in process when we get timeout. Affected file is
4830 lib/silcclient/client_keyagr.c.
4832 * Do not resolve the client ID forever if it returns in the
4833 first time that such client does not exist. This was done
4834 for example with private message. Affected file is
4835 lib/silcclient/client_prvmsg.c.
4837 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4839 * Do not add regex.h for WIN32. The affected file
4840 includes/silcincludes.h.
4842 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4843 not work yet 100%. It generates the DLL's automatically
4844 when compiling with --with-win32 under cygwin.
4846 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4848 * lib/contrib/regex.c is not compiled on WIN32.
4850 * Added silc_net_get_socket_opt function to the
4851 lib/silcutil/silcnet.h.
4853 * Added includes/silcwin32.h for WIN32 specific includes
4856 * Do not use ptime structure or any of the posix process
4857 functions on WIN32 in lib/silccrypt/silrng.c.
4859 * Added silc_gettimeofday to provide generic function
4860 for struct timeval on all platforms. Added the function
4861 to lib/silcutil/silcutil.h.
4863 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4865 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4866 library as they clearly belong there. As a plus side we
4867 can make the actual socket connection routines platform
4870 Added also new generic function silc_socket_read and
4871 silc_socket_write (that used to be silc_packet_[read/write].
4872 The implementation of these are platform specific.
4874 * Added WIN32 specific routines of silc_socket_[read/write]
4875 to lib/silcutil/win32/silcwin32sockconn.c.
4877 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4879 * Added preliminary support for native WIN32 compilation under
4880 cygwin (using the -mno-cygwin option for GCC) to the
4881 ./configure.in.pre. The --with-win32 now prepares the
4882 compilation for native WIN32.
4884 * Rewrote the SILC Scheduler interface in the file
4885 lib/silcutil/silcschedule.h. The scheduler is now context
4886 based and does not have anymore any global static scheduler.
4887 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4888 and created lib/silcutil/win32 directory for WIN32 based
4891 * Added Unix specific network routines to the
4892 lib/silcutil/unix/silcunixnet.c and the old
4893 lib/silcutil/silcnet.c includes now only generic routines.
4895 Added WIN32 specific network routines to the
4896 lib/silcutil/win32/silcwin32net.c.
4898 * Added Unix specific utility functions from the
4899 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4901 * Added WIN32 SILC Scheduler to the file
4902 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4905 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4907 * Do not handle JOIN notify in the server if the target client
4908 is not registered (idata->registered == FALSE). The affected
4909 file is silcd/packet_receive.c.
4911 * Update the nickrec->founder in event_cumode in the Irssi SILC
4912 client. Affected file irssi/src/silc/core/silc-channels.c.
4914 * Fixed the CUMODE_CHANGE notify handling in the server when
4915 server and router are announcing their clients on channels.
4916 Now the mode changes are saved and notified correctly. The
4917 affected file is /silcd/packet_receive.c.
4919 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4920 They really did not replace the cache entry in the ID Cache.
4921 Now they do that. Affected file silcd/idlist.c.
4923 * Fixed the KICK notify handling in the Irssi SILC client to
4924 update the channel records so that the kicked client does not
4925 appear to be on the channel. The affected file is
4926 irssi/src/silc/core/silc-channels.c.
4928 * Always update the conn->current_channel when executing command
4929 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4931 * Fixed the KILL notify handling in Irssi SILC client to remove
4932 the killed client on all channels.
4934 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Fixed the silc_parse_command_line to remove extra spaces
4937 from the start and end of the arguments. Affected file is
4938 lib/silcutil/silcutil.c.
4940 * Cancel and free any active protocol in the function
4941 silc_server_close_connection. Affected file silcd/server.c.
4943 * Cancel and free any active protocol in the function
4944 silc_client_close_connction. Affected file is
4945 lib/silcclient/client.c.
4947 * Do not execute the KILL command for clients that are in
4948 history (ie. they are not in the network). Affected file is
4951 * Fixed KILL notify handling, client does not crash anymore.
4952 Affected file irssi/src/silc/core/silc-channels.c.
4954 * Reduced the default packet buffer size from 2048 to 1024 in
4955 lib/silccore/silcpacket.c.
4957 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4958 counter to the SKE context that is incresed when the SKE library
4959 performs async operation outside the library. If the outside
4960 process frees the SKE context and FREED status will be set
4961 and the library will detect after the sync operation that the
4962 libary is freed. The affected files are
4963 lib/silcske/silcske[_status].[ch].
4965 * Resolve the client entry information in the function
4966 silc_client_channel_message to assure that NULL pointer is not
4967 passed as client entry to the application. */
4969 * Fixed the task timeout calculation to assure that there is
4970 never negative timeouts. The affected file is
4971 lib/silcutil/silcschedule.c.
4973 * Fixed the channel user mode notification sending in server.
4974 It was sent point-to-point to the router (or to server by router)
4975 but it needs to be destined to a channel. The routines now
4976 supports sending the channel user mode notifys to the channels
4977 when announcing clients and channels. Affected files are
4978 silcd/server.c and silcd/packet_receive.c.
4980 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4981 It did not actually replace the old channel entry in the cache.
4982 Affected file lib/silcclient/client_notify.c.
4984 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Fixed a possible crash in silc_packet_send_prepare. It now
4987 assures always that there is enough space in the buffer and
4988 at the tail area of the buffer (for MAC).
4990 Fixed the inbound buffer reallocation in silc_packet_read.
4991 It was old code and did not handle the reallocation correctly.
4994 The affected file is lib/silccore/silcpacket.c.
4996 * Fixed buffer overflow in silc_parse_nickname in the file
4997 lib/silcutil/silcutil.c.
4999 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * make install generates new server keys only if there is not
5004 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5007 Added check that if the NOREPLY is set then we will not send
5008 the away message. This avoids infinite loop of away messages
5009 if both clients are away. The affected file is
5010 lib/silcclient/client_prvmsg.c.
5012 * Fixed client crash if /NICK was given without arguments.
5013 Affected file lib/silcclient/command.c.
5015 * Server does not send the invite list in INVITE command back
5016 to the client if the list was not altered. Added this notion
5017 to the protocol spec as well. Affected file silcd/command.c.
5019 Fixed possible crash in INVITE command by checking the
5020 value of silc_server_get_client_route command.
5022 * Fixed the INVITE notify type handling. The arguments are now
5023 taken in correct order and client does not crash. The affected
5024 file is irssi/src/silc/core/silc-channels.c.
5026 Removed the "Inviting xxx to channel" message from the
5027 client library away and let the application handle it.
5028 Affected file lib/silcclient/command.c. Added that message
5029 to Irssi SILC client's message formats.
5031 * Fixed CMODE command crash in client. It now checks the
5032 amount of arguments correctly and does not crash. The affected
5033 file is lib/silcclient/command.c.
5035 * Do not create new channel automatically in silc_channels_join
5036 but check whether the channel by that name already exists.
5037 Affected file irssi/silc/core/silc-channels.c.
5039 * Do not send the SERVER_SIGNOFF to router if the disconnected
5040 entity was the router. Affected file silcd/server.c.
5042 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5043 SILC client as it was missing from there.
5045 Added the handling of the KICK notify to the Irssi SILC client
5046 as it was missing. Added "you have been kicked" message to
5047 Irssi SILC client's message modules formats.
5049 Added the handing of the KILL notify to the Irssi SILC client
5050 as it was missing. Added the kill message module formats
5053 The affected file is irssi/src/silc/core/silc-channels.c.
5055 * The router did not save the channel mode the server announced.
5056 Affected file silcd/packet_receive.c.
5058 * Fixed a possible crash in INFO command in server. If the
5059 server did not provide the server info it crashed. Affected
5060 file silcd/command.c.
5062 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Fixed the GETKEY command in the server to check also the
5065 global list. Otherwise the GETKEY would not work correctly
5066 in normal SILC server. Affected file silcd/command.c.
5068 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Fixed GETKEY crash, it crashed if the command did not succseed.
5072 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5075 is now real and not just an macro interface to GMP.
5077 Removed the entire GMP from the source tree and imported new
5078 NSS MPI library instead. Reason for removing GMP is that it is
5079 extremely large and compiles extremely slow. The NSS MPI
5080 is only a few files and compiles in less than 10 seconds.
5081 The speed is also about the same as GMP. The MPI is imported
5082 to lib/silcmath/mpi.
5084 If the system has GMP installed we will still use the GMP.
5085 If it is not then the NSS MPI will be compiled.
5087 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Merged a long nickname (127 characters long) crash bugfix from
5090 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5092 * Merged a freed memory reference bugfix from Irssi CVS tree.
5093 Affected file irssi/src/core/commands.c.
5095 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Added the server's public key sving and verification to the
5098 server when performing the SKE. This was missing and the
5099 remote server's (or router's) public key was accepted without
5100 checking whether we have it previously or trust it at all.
5101 Affected file silcd/protocol.c.
5103 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Check in the silc_server_timeout_remote if protocol is active
5106 and make sure that the protocol's final callback is called so
5107 that all memory if freed. Affected file silcd/server.c.
5109 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * silc_server_whois_send_reply crashed the server if the nickname
5112 was 127 characters long. Affected file silcd/command.c.
5114 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Added sanity check to the silc_server_new_client. If the hostname
5117 is provided inside username then check that the provided hostname
5118 really is the same as the resolved one. If the hostname was not
5119 resolved then check it from the public key. Affected file is
5120 silcd/packet_receive.c.
5122 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5123 if the server disconnected us and the connection is not valid
5124 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5126 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5127 the library to the lib/silcutil/silcutil.[ch].
5129 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Close log file after open. Affected file
5132 lib/silcutil/silclog.c.
5134 * Check whether sock == NULL in silc_client_send_packet and return
5135 if it is. Affected file lib/silcclient/silcclient.c.
5137 * Check rec->entry == NULL in the Irssi SILC Client before
5138 sending the channel message. Affecte file is
5139 irssi/src/silc/core/silc-servers.c.
5141 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Merged a splitted window bugfix from Irssi CVS tree. The
5144 affected file is irssi/src/fe-text/textbuffer-view.c.
5146 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5147 It did not print nickname.
5149 * Improved the distributions system a bit.
5151 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5154 irssi/src/fe-text/gui-window.c.
5156 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5157 to in-active server. The affected file is
5158 irssi/src/silc/core/client_ops.c.
5160 * Resolve the client in USERS command reply if the entry does
5161 not have username resolved. The affected file is
5162 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5163 command to WHOIS command to really resolve stuff. The USERS
5164 is not used any more in any critical section so WHOIS can
5165 be used even though it might be slower than IDENTIFY.
5167 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5170 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Changed the protocol API a bit more consistent in the
5173 lib/silccore/silcprotocol.[ch].
5175 * Changed the following headers to ROBODoc format:
5177 lib/silccore/silcpayload.h
5178 lib/silccore/silcprotocol.h
5179 lib/silccore/silcsockconn.h
5181 All core library headers are now formatted.
5183 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Fixed a bug in Irssi SILC client; do not show that you are
5186 server/router operator if you really are not. Affected file is
5187 irssi/src/silc/core/client_ops.c.
5189 * Renamed silc_command_free_payload to silc_command_payload_free.
5190 Affected file lib/silccore/silccommand.h
5192 * Added silcmath.h to include the prototoypes of various routines
5193 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5196 * Changed the following headers to ROBODoc format:
5198 lib/silccore/silcchannel.h
5199 lib/silccore/silccommand.h
5200 lib/silccore/silcid.h
5201 lib/silccore/silcidcache.h
5202 lib/silccore/silcmode.h
5203 lib/silccore/silcnotify.h
5204 lib/silccore/silcpacket.h
5205 lib/silcmath/silcmath.h
5207 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Added checking to the server code not to start the server if
5210 ciphers and stuff are not configured properly. Affected files
5211 silcd/serverconfig.[h] and silcd/server.c.
5213 * Changed the layout of the header files of the public interfaces
5214 in the SILC libraries. The new layout supports ROBODoc
5215 documentation tool (and some others) so that it is easy to create
5216 a library reference manual. All the other headers and source
5217 code must still follow the CodingStyle document. Also source
5218 code must not include these ROBODoc stuffs, only the headers.
5219 Furthermore, all public interface headers must now be named
5220 by using `silc' prefix, example: silcapi.h, silccipher.h.
5221 Some files were renamed due to this. All the other headers
5222 must not be used as public interfaces. I will update the
5223 CodingStyle document later. Changed following headers, so far:
5225 lib/silcclient/silcapi.h
5226 lib/silccore/silcauth.h
5227 lib/silccore/silcprivate.h
5228 lib/silccrypt/silcdh.h
5230 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Removed silc_client_packet_send_flush from the client library
5235 as it is not needed. Affected file lib/silcclient/client.[ch].
5237 * Added printing of message of unresolved authentication method
5238 to the Irssi SILC client. Added it to the module formats.
5239 Removed the same message from the client library.
5241 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added new distribution feature, DISTLABEL. Every distribution
5244 can define own preprocessor label that can be used in the
5245 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5246 file distributions, acconfig.h.pre and prepare.
5248 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Added Makefile.defines_int to include the actual definitions
5251 for Makefile.defines.in. Tested the new distribution system,
5252 created distributions and tested installation.
5254 * Added AWAY message printing to the Irssi SILC client. Added
5255 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5257 * Added SCONNECT command to call the SILC's CONNECT command.
5258 Cannot use CONNECT directly since Irssi uses that internally.
5259 Affected file irssi/src/silc/core/silc-servers.c.
5261 Added ACTION local command. It is same as ME command but takes
5262 the channel as mandatory argument.
5264 Rewrote some of the Irssi's help files to suite for SILC
5267 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added Makefile.defines[.in] that should for now on be included
5270 in all Makefile.am file in the source tree. That file includes
5271 all common compilation definitions for SILC source tree.
5273 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Minor changes to the ./prepare script to change the package
5276 name according the distribution name to the configure.in.
5278 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Created new distribution system. Added file `distributions'
5281 that defines all the distributions that can be created out of
5282 the SILC source tree. The ./prepare script now reads that
5283 file to determine how to prepare the distributions. The
5284 first argument to the ./prepare is the name of the distribution
5285 and second is the version of the distribution. If given
5286 without arguments it creates the default (toolkit) distribution
5287 with the default version (defined in ./prepare).
5289 All Makefile.am files that are subject to the distributions
5290 are now named as Makefile.am.pre. These are ./Makefile.am
5291 and lib/Makefile.am. Others may be changed later.
5293 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Added invite list, ban list, some key management and connection
5296 error message printing to module formats in the Irssi SILC client.
5298 * Added new silc_client_set_away_message to set the away message
5299 that is back to the person who sent private message. The
5300 affected file lib/silcclient/silcapi.h and the
5301 lib/silcclient/client_prvmsg.c.
5303 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Fixed the private message sending in the Irssi SILC client,
5306 added local command KEY to the Irssi SILC client.
5308 Added key management and key agreement message formats to the
5309 irssi/src/fe-common/silc/module-formats.[ch].
5311 Added USERS (alias WHO) printing, server/router operator
5312 indication and LIST command printing to the module formats.
5314 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Fixed channel joining notify handling, cumode notify handling
5317 from Irssi SILC client.
5319 * Added SILC specific module-formats to the Irssi SILC client so
5320 that SILC specific message hilighting, colors etc is possible.
5321 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5323 Added channel mode, channel user mode, actions, notices,
5324 whois and whowas printing to the the module-formats.c.
5326 * Fixed a bug in channel deletion in the server. The channel
5327 is not left to the cache even if the channel founder auth mode
5328 is set when there are no users anymore on the channel. Affected
5329 file silcd/server.c.
5331 * The silc_net_localhost now resolves the entire hostname including
5332 the domain name. Affected file lib/silcutil/silcnet.c.
5334 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5336 * Changed the ask_passphrase client operation to be ascynchronous.
5337 It has now a completion callback and a context that the
5338 application must call after it has got the passphrase from
5339 the user. Affected files lib/silcclient/silcapi.h,
5340 lib/silcclient/protocol.c, lib/silcclient/command.c and
5343 Added SilcAskPassphrase callback that the application calls
5344 to deliver the passphrase to the library.
5346 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5347 The public key verification and especially a certificate
5348 verification is asynchronous procedure.
5350 Added new SILC_SKE_STATUS_PENDING status to indicate the
5351 request is pending and a callback will be called to finalize
5354 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5355 indicate that remote end did not send its public key (or
5356 certificate), even though we require it. Added check for this
5357 condition in the SKE. This was a security bug, now fixed.
5359 Defined new SilcSKEVerifyCbCompletion callback that is called
5360 when the verification process is completed.
5362 The affected files lib/silcske/silcske_status.h and
5363 lib/silcske/silcske.[ch].
5365 * Changed the verify_public_key client operation to be async
5366 as well. Defined SilcVerifyPublicKey callback that is used to
5367 indicate the success of the public key verification process.
5369 Changed the server and client to use the new async client
5372 * Changed the Irssi SILC client's internal scheduler to be called
5373 twice as many times as it used to be. As a result the client
5374 should be a bit faster now. Affected file is
5375 irssi/src/silc/core/silc-core.c.
5377 * Added support to Irssi SILC client of asynchronous public key
5378 verification and passphrase inquiry. Affected file is
5379 irssi/src/silc/core/silc-core.c.
5381 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Do not say "You have left channel %s" in client library.
5384 Moved it to the application. Affected files are
5385 lib/silcclient/command.c and silc/client_ops.c.
5387 * Fixed silc_client_get_clients. Command context was not
5388 duplicated and was freed memory in the callback. Affected
5389 file lib/silcclient/idlist.c.
5391 * Do not say "you are now talking..." on JOIN command in the
5392 client library. The appliation must handle it.
5394 * Do not say ".. changed topic to" in command reply in the
5395 client libary. The application must handle it.
5397 * Fixed TOPIC command sending in the client library.
5399 * Fixed a memory leak in silc_client_command_free in the file
5400 lib/silcclient/command.c.
5402 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Imported a modified version of Irssi client to the source tree.
5405 The Irssi will be used to create a new client called
5406 Irssi SILC. Imported to irssi/.
5408 Added silc_core_init_finish function to the Irssi. Affected
5409 file irssi/configure.in.
5411 A lot changes in the Makefile.ams around the irssi tree.
5413 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Do not rehash if the new size is same as the old size of the
5416 hash table, in the silc_hash_table_rehash*. The affected file
5417 lib/silcutil/silchashtable.c.
5419 * Replaced hash_table_del_by_context calls from the server
5420 (when channel->user_list and client->channels) to the
5421 hash_table_del as it is sufficient and faster.
5423 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Added silc_hash_table_list, silc_hash_table_get and the
5426 SilcHashTableList structure to provide an alternative way to
5427 traverse the hash table. The affected files are
5428 lib/silcutil/silchashtable.[ch].
5430 * Changed the server's idlist routines to use the hash table
5431 routines to optimize the code.
5433 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Replaced the client entry's `channel' list and channel entry's
5436 `user_list' list to hash tables for optimized lookup. Changed
5437 the code to use the hash table interface around the code.
5438 Affected file lib/silcd/idlist.[ch].
5440 * Added `auto_rehash' boolean argument to the function
5441 silc_hash_table_alloc to indicate whether the hash table should
5442 auto-rehash when it thinks is appropriate time. It will
5443 increase the hash table size if the there is twice as much
5444 entries in the table than the size of the table, and will
5445 decrease the size if there are twice as less entries than
5446 the size of the table.
5448 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5452 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * silc_idcache_purge_by_context deletes the entry now by context
5455 as it is supposed to do. Affected file lib/silccore/idcache.c.
5457 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5458 client is not anymore valid (WHOWAS givens the info) and not
5459 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5461 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Removed the `data' and `data_len' arguments from the ID Cache
5464 interfaces and added `name' argument. ID Cache does not handle
5465 anymore the binary data only a names associated with given ID.
5467 * When hashing a Client ID with silc_hash_id the entire ID is
5468 not hashed anymore, instead only the hash of the Client ID is
5469 hashed. This way we can access the Client ID from the cache
5470 with Client ID but with the hash of the ID (which is a hash of
5471 the nickname) as well without any difference in performance.
5473 Added also silc_idcache_find_by_id_one_ext to do one on one
5474 searching when we have the actual ID. Added also function
5475 silc_hash_client_id_compare. The affected files are
5476 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5478 * When hashing the name associated with a ID it is always done
5479 in lowercase. This way we can access the cache without worrying
5480 about case-sensitivity, even though, for example nicknames are
5483 * Fixed a bug in server with channel message sending. It put
5484 wrong ID type as destination ID. The affected file
5485 silcd/packet_send.c.
5487 * silc_idcache_del_by_context now deletes from all hash tables
5488 by context. Affected file lib/silccore/idcache.c.
5490 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Changed the client library to use the new ID Cache interface.
5493 Changes around the source tree.
5495 * Added silc_hash_table_rehash_ext to rehash with specific
5496 hash function. Affected file lib/silcutil/silchashtable.[ch].
5498 * Added silc_hash_string_compare to compare two strings in the
5499 hash table. Affected file lib/silcutil/silcutil.[ch].
5501 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Added new function silc_idcache_del_by_context into the
5504 lib/silccore/idcache.[ch].
5506 * Changed the server's ID list routines to use the new ID Cache
5507 interface. Changes around the source tree.
5509 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Added silc_hash_table_del[_by_context]_ext functions in to the
5512 lib/silcutil/silchashtable.[ch].
5514 Removed silc_hash_table_find_all* routines and added new
5515 silc_hash_table_find_foreach to replace them.
5517 Added silc_hash_table_replace_ext function as extended
5518 replacing function. Separated the simple hash table interface
5519 from the extended hash table interface in the file
5520 lib/silcutil/silchashtable.h.
5522 * Fixed minor bugs and changed it to use some of the new
5523 hash table functions in lib/silccore/idcache.c
5525 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Added new function silc_hash_table_find_all to return all keys
5528 in the hash table by the specified key. As the hash table is
5529 collision resistant it also makes it possible to have several
5530 duplicate keys in the hash table. This function may be used to
5531 find all of the keys from the hash.
5533 Added user_context arguments to the SilcHashFunction,
5534 SilcHashCompare and SilcHashDestructor to deliver user specified
5537 Added new fuctions silc_hash_table_find[_all]_ext to do
5538 extended lookup with specified hash and compare functions and
5539 specified user contexts.
5541 Added new function silc_hash_table_add_ext to add the key
5542 with specified hash function and user context.
5544 Added new function silc_hash_table_foreach to traverse all
5545 entrys in the hash table. Added SilcHashForeach callback
5548 Added new function silc_hash_table_del_by_context to delete
5549 the entry only if the context associated with the key matches.
5551 Affected files are lib/silcutil/silchashtable.[ch].
5553 * Removed silc_hash_[server/client/channel]_id and added just
5554 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5555 silc_hash_id_compare to compare two ID's using as the hash table
5556 comparison function. Added also silc_hash_data to hash
5557 binary data and silc_hash_data_compare to compare it.
5559 * Removed silc_idlist_find_client_by_hash as it is not needed
5560 anymore. Affected file silcd/idlist.[ch].
5562 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5563 to use internally the SilcHashTable. The new ID Cache is a lot
5564 faster than the old one. Some of the ID Cache interface was also
5565 rewritten and obsolete and stupid functions were removed.
5567 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Added entry_count field to the SilcHashTable to keep the number
5570 of the entries in the table. Implemented the function
5571 silc_hash_table_rehash. Added new function
5572 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5574 Fixed a minor bug in silc_hash_table_free.
5576 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5577 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5578 into the lib/silcutil/silcutil.[ch].
5580 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Implemented a collision resistant hash table into the
5583 lib/silcutil/silchashtable[ch]. See the header and the source
5584 for the SilcHashTable API.
5586 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Merged dotconf version 1.0.2 into lib/dotconf.
5590 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Do not compile anything in lib/silcsim/* if the SIM support
5593 is not enabled. The tree should now compile without problems
5596 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Compiled the SILC under cygwin. Compiled and tested briefly
5599 without problems. More tests needed. The SIMs didn't compile
5602 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5604 * Fixed possible crash in silc_get_username in the
5605 lib/silcutil/silcutil.c.
5607 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Fixed a va_arg in silc/client_ops.c.
5611 * Oops, RC5 routines were named AES and caused some problems
5612 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5614 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added new SilcIDIP structure into the lib/silccore/id.h and
5617 replaced the old `ip' fields from all SILC ID's to that type.
5618 This is a step towards IPv6 support.
5620 The silc_id_get_len takes now the ID as an extra argument.
5621 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5622 both IPv4 and IPv6 based ID's.
5624 The affected files are lib/silccore/id.[ch] and other files
5625 around the tree using these routines.
5627 * Removed the ID length arguments in server from various
5628 silc_server_send_notify_* routines -> they are not needed
5631 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Fixed memory leak in silc_encode_pem_file in the file
5634 lib/silcutil/silcutil.c.
5636 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Check minor version as well in the SKE. Affected files are
5639 silcd/protocol.c and lib/silcclient/protocol.c.
5641 * Added --identifier option to the server so that an identifier
5642 can be when creating the public key for the server. Affected
5643 file is silcd/silcd.c.
5645 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5646 lib/silccrypt/silcpkcs.c.
5648 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Register default ciphers and stuff when using -C option with
5651 the server. Affected file sildc/silcd.c.
5653 * Put back the servers public key filename format, it is better
5654 than the new one. For now, the client keys are saved with the
5655 new filename format. The affected file silc/client_ops.c.
5657 * Implemented the Cipher API for the rest of the ciphers that
5658 did not implement it or implemented it the wrong way.
5660 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Register default ciphers and stuff when using the -S option
5663 in the client. Affected file silc/silc.c. Same also when
5664 creating new key pair with -C option.
5666 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Fixed the silc_verify_public_key client operation function to
5669 save the public keys differently. The fingerprint is now
5670 used as filename and not the hostname. This way also the
5671 client keys are saved uniquely and not with hostnames. The
5672 affected file is silc/client_ops.c.
5674 * Trimmed the silc_hash_fingerprint function to remove extra
5675 whitespaces from the end of the fingerprint. The affected
5676 file is lib/silccrypt/silchash.c.
5680 * Added silc_cipher_register_default function to register all
5681 default ciphers. It can be used when configuration files
5682 does not exist and the application does not want any specific
5683 ciphers in any specific order.
5685 The SilcDList is now used as silc_cipher_list dynamically
5686 allocated cipher list. Removed the static list all together
5687 and now all ciphers must be allocated to the dynamic list.
5688 The silc_cipher_alloc routine was changed to check only the
5691 All silc_cipher_* routines that used to return int returns
5694 The affected files lib/silccrypt/silccrypt.[ch].
5696 * The same thing was done to silc_hash_* as for silc_cipher_*
5697 routines. Affected files lib/silccrypt/silchash.[ch].
5699 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5700 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5701 Added also silc_pkcs_[un]register[_default] functions.
5702 Removed the data_context from the PKCS API.
5704 * Added silc_hmac_register_default function to register default
5705 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5706 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5707 to unregister all hmacs at once.
5709 * Register the default ciphers, hash functions, PKCSs and HMACs
5710 if client's configuration file does not exist. The affected
5713 * The client did not load the hash functions from the SIM
5714 modules at all. Added support for this. Affected file is
5715 silc/clientconfig.c.
5717 * When decoding public key with silc_pkcs_public_key_decode, check
5718 the supported algorithm only if PKCS are registered. Affected
5719 file lib/silccrypt/silcpkcs.c. The same was done with the
5720 silc_pkcs_private_key_decode.
5722 * Fixed the SILC List routines to keep the list always in order.
5723 It used to change the list's order when traversing the list but
5724 not it preserves the order. Affected file lib/trq/silclist.h.
5726 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Added the client library to use the SilcSocketConnection's
5729 reference counter (by silc_socket_dup) to prevent the bug that
5730 the socket object may be freed underneath async operation.
5732 * The name resolv library checking fixes in the configure.in.pre.
5735 * Created new version of the protocol drafts for future
5736 development. The -03 drafts are the ones that will be changed
5737 in the trunk now and the -02 will remain as they are.
5739 * Send list of CUMODE notifys to the router when announcing
5740 the channel users to the router. Affected file silcd/server.c.
5741 If the router receiving channel founder CUMODE for a channel
5742 that already has channel founder it will send CUMODE notify
5743 to the sender to remove the channel founder rights from the
5744 announced client. Affected file silcd/packet_receive.c.
5746 * The CUMODE notify may now use Server ID as well as the entity
5747 who changes the mode. Updated protocool specs.
5749 * Updated INSTALL and README files.
5751 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * New web pages in the http://silc.pspt.fi. The pages was
5758 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Implemented the [DenyConnectin] config section in the server.
5761 Added silc_server_config_denied_conn to check whether incoming
5762 connection is denied. Affected file silcd/serverconfig.[ch].
5764 * Do not check the ports when checking the incoming configuration
5765 data if the port is 0, meaning any. Affected file is
5766 silcd/serverconfig.c.
5768 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Fixed buffer overflow in silc_string_compare in the file
5771 lib/silcutil/silcutil.c.
5773 * Fixed double free in silc_server_command_leave in the file
5776 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Fixed the version checking in the server. Affected file is
5781 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Fixed the configuration data fetching when accepting new
5784 connections in the server. Affected file silcd/server.c.
5786 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Added `sender_entry' argument to the function
5789 silc_server_packet_relay_to_channel so that we can check
5790 whether some destination actually belongs to the same route
5791 the sender belongs (ie, we must not resend the packet to the
5792 sender). Affected file silcd/packet_send.[ch].
5794 * Added `servername' field to the SilcClientEntry in the server
5795 to hold the name of the server where client is from. Affected
5796 file is silcd/idlist.h.
5798 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Moved the channel message encrypting in the router betwen
5801 router connections from silc_server_channel_message to the
5802 silc_server_packet_relay_to_channel since we want to check
5803 whether we have anybody channel before encrypting anything.
5804 Affected files silcd/packet_[receive/send].c.
5806 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Fixed the [AdminConnection] server config section to support
5809 multiple entries. Affected file silcd/serverconfig.c.
5811 * Added support into the server to check the validity of the
5812 incoming connection before executing any KE or authentication
5815 * The connection configuration is now saved to the KE and
5816 connection auth protocol contexts and not fetched anymore in
5817 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5819 * The local hosts listenning address and port is also resolved
5820 now when starting the server. We want to have the socket object
5821 to include the real address and port for the listener. Added
5822 new function silc_net_check_local_by_sock into the files
5823 lib/silcutil/silcnet.[ch].
5825 * Fixed a broadcast bug in server -> do not broadcast if we
5828 * Fixed a routing bug. Do not route broadcast packets ever.
5829 Broadcast packets must be processed always and not routed since
5830 they may be destined to some other host than yourself and thus
5831 would get routed without no good reason. Affected file is
5834 * Added function silc_server_config_is_primary_route to check
5835 whether primary router connection has been configured (a router
5836 configuration that we are initiating). If there is not, we
5837 will assume that there is only two routers in the SILC network
5838 and we will use the incoming router connection as our primary
5839 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5841 * Changed the order of the broadcasting. Broadcast _after_ the
5842 packet has been processed not before. Affected file is
5845 * Fixed a [ClientConnection] parsing bug. The port was never
5846 parsed correctly thus resulting to port 0. Affected file
5847 silcd/serverconfig.c.
5849 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5850 argument and did not set the broadcast packet flag. Affected
5851 file silcd/packet_send.c. Fixed same bug in the function
5852 silc_server_send_notify as well.
5854 * If we receive NEW_ID packet for our own ID in the server, ignore
5857 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Removed the nickname from the Private Message Payload.
5862 Updated the code and the protocol specs.
5864 * Updated protocol specs for submitting to the IETF.
5866 * Tweaked the Random Number Generator a bit. Affected file
5867 lib/silccrypt/silcrng.c. Exported a new function
5868 silc_rng_[global]_add_noise which can be used to add more
5871 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Do not parse packets with different timeout when protocol
5874 is active -> may cause problem with rekey. Affected file
5877 * When server receives signoff notify it must not create
5878 new channel key if the client is on any channels since the
5879 sender of the signoff notify will create it.
5881 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added printing of error messages during SKE protocol from the
5884 failure packet sent by server during SKE. Affected file
5887 * Removed the client's failure_callback handling with timeout
5888 and handle it immediately when received.
5890 * The SKE library returned wrong type in SUCCESS and FAILURE
5891 packets. They must be 32 bit MSB not 16 bit MSB.
5893 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Ok, rewrote the logic of the re-key and now it seems to work.
5896 I tested it on high traffic with frequent re-keys without
5897 problems. Added hmac_receive (and renamed hmac to hmac_send)
5898 in SilcClientConnection in lib/silcclient/client.h and
5899 in SilcIDListData in silcd/idlist.h. Also, removed the
5900 SilcPacketParserContext's cipher and hmac fields as they are
5901 not needed anymore and actually caused some problems when
5902 the ciphers and hmac's changed underneath the packet parser.
5904 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * If re-key protocol is active then process the incoming packets
5907 synchronously since we must assure that icoming packets encrypted
5908 with the old key is processed before the new keys is set to
5909 use. This is true other packets than for REKEY packets.
5910 Affected file silcd/server.c. The same was done to client library
5911 as well, affected file lib/silcclient/client.c.
5913 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Fixed bug in client and server to accept the force send if
5916 the packet is send from silc_[server/client]_packet_process
5917 function. Otherwise the packets are never delivered, oops.
5919 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Disable force sending of packets when REKEY protocol is active.
5922 We must assure that no packet is sent directly when rekey is
5923 performed. All packets must be sent through packet queue.
5924 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5925 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5926 function is silc_[server/client]_packet_send_real to check
5929 * Replaced the SIM paths from example config files to
5930 /usr/local/modules. Also, make install creates now
5931 /usr/local/silc/logs directory to hold all the SILC server
5934 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Made the configure.in.pre work on Solaris. Patch by salo.
5938 * Made all ciphers compatible with non-x86 machines. Defined
5939 CBC mode macros into lib/silccrypt/ciphers_def.h.
5941 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Fixed the make install.
5945 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * When MAC computation fails the silc_packet_decrypt returned 0
5948 even though it was supposed to return -1. Fixed this. The
5949 affected file is lib/silccore/silcpacket.c.
5951 * Do not replace the config files in /etc/silc (in make install)
5952 if they already exist. Affected file ./Makefile.am.
5954 * Do not send re-key packets immediately but through packet queue.
5955 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5957 * Changed silc_net_check_host_by_sock to return FALSE if the
5958 IP/DNS could not be resolved. Though, it returns the IP address
5959 now even if it could not resolve it (but returns also FALSE).
5960 Affected file lib/silcutil/silcnet.[ch].
5962 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Added silc_pkcs_decode_identifier to decode the public key's
5965 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5966 Added also silc_pkcs_free_identifier. Added also new context
5967 SilcPublicKeyIdentifier.
5969 * Added -S option to the silc client. It is used to dump the
5970 contents of the specified public key file.
5972 * Changed the PKCS api to return the public key length when
5973 setting the public key.
5975 * Fixed a fatal bug in the public and private key file loading.
5976 Affected file lib/silccrypt/silcpkcs.c.
5978 * Execute the packet parsing for client with zero (0) timeout
5979 if the protocol is active. Affected file silcd/server.c.
5981 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Made the key generation options to the silcd program. Added
5984 -C option, equivalent to client's option.
5986 * Added new [ServerKeys] config section to the server. It
5987 configures the server's public and private key.
5989 * Defined generic Public Key Payload into the protocol
5990 specification to send specific type of public keys and
5993 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5994 public key or certificate.
5996 * Implemented the GETKEY command to the server and to the
5997 client library and on user interface.
5999 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Made preliminary `make install' work.
6003 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Added SilcServerRekey context into silcd/idlist.h.
6007 * Added the PFS support as defined in the specification to the
6008 SKE protocol. Affected files lib/silcske/*.c.
6010 * Added `ske_group' field to the SilcServerRekey context to hold
6011 the number of the SKE group that is used with PFS in re-key.
6012 Affected file silcd/idlist.h.
6014 * Added PFS re-key support to the server. Affected file is
6017 * Added silc_protocol_cancel to cancel execution of the next
6018 state of the protocol. Affected file is
6019 lib/silccore/silcprotocol.[ch].
6021 * Added the re-key support with and without PFS to the client
6022 library. Re-key is performed once in an hour, by default.
6024 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6025 Added silc_client_rekey_callback and silc_client_rekey_final.
6026 Affected files are lib/silcclient/protocol.[ch] and
6027 lib/silcclient/client.[ch].
6029 * Removed the `hmac_key' and `hmac_key_len' fields from the
6030 SilcClientConnection structure; not needed. Affected file is
6031 lib/silcclient/client.h.
6035 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Do not ask whether user wants to use the negotiated private key
6038 for private messages, just use it. Affected file is
6039 silc/local_command.c.
6041 * Added `send_enc_key' and `enc_key_len' fields to the
6042 SilcIDListData structure since they are needed in the re-key
6043 phase. Affected file is silcd/idlist.[ch].
6045 * Implemented the simple re-key protocol into the server.
6046 Affected files silcd/server.c and silcd/protocol.[ch]. The
6047 re-key will be performed once in an hour, by default.
6049 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6050 Added silc_server_rekey, silc_server_rekey_callback and
6051 silc_server_rekey_final.
6053 * Removed Tunneled flag from the protocol. Updated the code
6054 and the specifications.
6056 * Adde `pfs' field to the SilcIDListData to indicate whether
6057 the PFS is to be performed in the re-key. Affected file is
6060 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6063 int64 of at least the xintXX size. If void * is less that 4
6064 bytes uint32 * will be used. Defined bool as boolean.
6066 * Changed _ALL_ unsigned long and unsigned int to uint32,
6067 unsgined short to uint16 in the source tree.
6069 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6070 not handle clients that has entry->data.registered == FALSE.
6071 They are not in the network anymore. Affected file is
6074 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Implemented the sending of the SERVER_SIGNOFF notify in the
6077 server. Affected file is silcd/server.c.
6079 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6080 Added also silc_notify_payload_encode_args into the
6081 lib/silccore/silcnotify.[ch].
6083 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6084 Affected file silcd/packet_receive.c.
6086 * Implemented the SERVER_SIGNOFF notify handling in the client
6087 library. Affected file lib/silcclient/client_notify.c. Also,
6088 implemnted the printing of the SERVER_SIGNOFF info to the
6089 application. Affected file silc/client_ops.c.
6091 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6092 if the deleting was successful. Affected file silcd/idlist.[ch].
6094 * Added support for public key authentication in the connection
6095 authentication protocol in the client library. Affected file
6096 lib/silcclient/protocol.c.
6098 * Changed the server's silc_idlist_get_clients_by_* interface
6099 to support already allocated array so that new entries may be
6100 added to pre-allocated array. Affected file silcd/idlist.[ch].
6101 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6102 and command replies.
6104 * All command reply functions in the server now calls the
6105 pending command callback even if error occured. This way the
6106 error will be delivered to the client as well. Affected files
6107 silcd/command.c and silcd/command_reply.c.
6109 * Fixed INFO command to return local server's info if no server
6110 was provided. Affected file lib/silcclient/command.c.
6112 * Removed RESTART command for good. Updated the code and the
6115 * Rewrote parts of the task system. It is a bit simpler now.
6116 Removed unsued task priorities. The affected files are
6117 lib/silcutil/silctask.[ch].
6119 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Moved the USERS printing from the library to the application.
6122 Affected files lib/silcclient/command.c and silc/client_ops.c.
6124 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Added channel key re-key support. The re-key is perfomed
6129 only by the router and is done once in an hour. Added `rekey'
6130 field to the SilcChannelEntry in the server. Affected files
6131 silcd/server.c and silcd/idlist.h.
6133 * Added silc_task_unregister_by_context into the file
6134 lib/silcutil/silctask.[ch].
6136 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Added SILC_UMODE_GONE mode to indicate when the client is not
6139 present in the SILC network. Added also support to the local
6140 command AWAY that will set this mode. Added support of showing
6141 "xxx is gone" in WHOIS command. The USERS command shows the
6142 gone status as well.
6144 * Fixed setting server and router operator privileges in the
6145 server's UMODE command. Affected file silcd/command.c.
6147 * Merged the SKE KE1 and KE2 payloads into one payload. The
6148 new KE payload is equivalent to the old KE2 payload.
6150 Cleaned up the SKE Start Payload parsing. It now uses the
6151 simple buffer unformatting to do the parsing. A lot faster
6154 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6155 to the SKE that is used to indicate whether both of the SKE
6156 parties should perform authentication. By default only the
6157 responder performs authentication. By setting this flag also
6158 the initiator must do authentication. By default it is unset
6159 since in normal SKE case, client to server connection, only
6160 the responder should do authentication. When doing SKE between
6161 two clients both should perform authentication. Updated the
6162 code and the protocol specs.
6164 * A little fix to IDENTIFY command in the server. Search the
6165 client first by hash not nickname. Affected file is
6168 * Fixed the silc_client_close_connection to support closing
6169 the client to client connections wihtout deleting too much
6170 data. Affected file lib/silcclient/client.c.
6172 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6173 are received if protocol used to be active but is not anymore
6174 the application would crash due to NULL pointer dereference.
6175 Affected files silcd/server.c and lib/silcclient/client.c.
6177 * Added `hash' field to the SilcClientConnection to include
6178 the hash function negotiated in the SKE protocol.
6180 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6181 to set the channel founder authentication data. A client can
6182 claim the founder rights later by providing the authentication
6183 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6184 This way the channel founder can regain the channel founder
6185 privileges even it is left the channel. This works only on
6186 local server and the client must be connected to the same
6187 server to be able to regain the founder rights. Updated the
6188 protocol specs accordingly.
6190 Added support to the CMODE command in the client to set the
6191 founder auth data. Read the README to see how to set it.
6193 Added support to the CUMODE command to claim the founder
6194 rights. Read the README to see how to do it.
6196 Added support for the founder authentication to the Channel
6197 Entry in the server. Affected file silcd/idlist.h.
6199 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6200 server's CMODE command. Affected file silcd/command.c.
6202 * Added the following new functions into lib/silccore/silcauth.[ch]:
6203 silc_auth_get_method and silc_auth_get_data.
6205 * The server now saves the remote hosts public key to the
6206 SilcIDListData pointer. Affected file silcd/protocol.c.
6208 * The normal server now does not remove the channel entry from
6209 the cache if the founder authentication data is set. It used
6210 to remove it if the founder was the last one on the channel on
6211 the server and left the channel. The auth data is saved and
6212 if the channel is re-joined later the old entry is used with
6213 the old auth data. Affected files silcd/command_reply.c and
6216 * Removed the `pkcs' field from the SilcIDListData structure
6217 in the server; it is not used. Affected file silcd/idlist.h.
6219 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Fixed packet processing on slow links. Partial packets were
6222 never re-processed because the incoming data buffer was cleared
6223 by the application. Application must not directly clear the
6224 sock->inbuf, the packet processing routines handle it. Fixed
6225 this in client library and in server.
6227 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * Fixed the WHOIS and IDENTIFY send reply function to really
6230 check whether to send list or just one entry. Affected file
6233 * Cleaned up the LEAVE command's channel key distribution. The
6234 affected file silcd/command.c.
6236 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6237 can enforce the channel mode as well. In that case the ID
6238 includes the ID of the server. The code now enforces the
6239 mode change if the router have different mode than the server.
6241 * The notify client operation with CMODE_CHANGE notify can now
6242 return NULL client_entry pointer if the CMODE was not changed
6243 by client. Application must check for this.
6245 * Added <Server ID> argument to INFO command to support server
6246 info fetching by Server ID.
6248 * Added silc_server_announce_get_channel_users to get assembled
6249 packets of channel users of the specified channel. Affected
6250 file silcd/server.[ch].
6252 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6253 was freed underneath the ID Cache.
6255 * Re-announce clients when the server received CHANNEL_CHANGE
6256 notify from the router. Affected file silcd/packet_send.c.
6258 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6261 crashed since it did not handle the fact that there is no cipher
6262 called "3" and didn't check the error condition. Now fixed.
6264 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6265 flag. It can be used to send message requests.
6267 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6269 * Implemented the RESTART command in the client.
6271 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6272 notice type messages. Added notice printing to the user
6275 * The channel keys are not re-generated if the channel's mode
6276 is PRIVKEY, ie private key on the channel exists. Affected
6277 files silcd/server.c and silcd/command.c.
6279 * Fixed a little bug in channel message delivery when channel
6280 private keys are set in the server. Affected file is
6281 silcd/packet_send.c.
6283 * Changed the setting on channel->on_channel = TRUE from the
6284 silc_client_save_channel_key to the JOIN command reply. The
6285 key payload is not received if the private channel key is set.
6286 Affected file lib/silcclient/command_reply.c and the
6287 lib/silcclient/client_channel.c.
6289 * When the CMODE_CHANGE notify is sent and the channel private
6290 key mode is removed the channel key must be re-generated in
6291 other cells as well. Added this support for the router in the
6292 silcd/packet_receive.c.
6294 * Added new local command NOTICE to send notice message on
6295 channel. Affected file silc/local_command.[ch].
6297 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Added new local command ME to the client. It is used to send
6300 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6301 some action. Affected file silc/local_command.[ch].
6303 * Changed channel_message and private_message client operations
6304 to deliver the message flags to the application. Added also
6305 the `flags' arguments to the silc_client_send_channel_message
6306 and silc_client_send_private_message functions. Affected file
6309 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Redefined the Private Message Payload to support private message
6312 keys and to support the new private message flags. Updated
6313 the protocol specs. Flags makes it possible to have for example
6314 CTCP style messages.
6316 * Added new type SilcPrivateMessagePayload and defined an API
6317 for it in the lib/silcclient/silcprivate.[ch].
6319 * Tested private message private keys successfully. Tested the
6320 private message key set, unset and list commands with the new
6323 * Redefined the Channel Message Payload to include the channel
6324 message flags (equal with private message flags) to support
6325 for example CTCP style messages.
6327 * Defined some of the message (for channel and private message)
6328 flags. Updated the protocol specs and added the flags to the
6329 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6331 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Added SilcKeyAgreementStatus type to the key agreement routines
6334 to indicate the current status and error if one occured.
6335 The status types are defined in the lib/silcclient/silcapi.h.
6337 * Added new local command KEY that is used to set and unset private
6338 keys for channels, set and unset private keys for private messages
6339 with remote clients and to send key agreement requests and
6340 negotiate the key agreement protocol with remote client. The
6341 key agreement is supported only to negotiate private message keys,
6342 it currently cannot be used to negotiate private keys for channels,
6343 as it is not convenient for that purpose.
6345 * Fixed a minor pending callback setting bug in the function
6346 silc_client_get_client_by_id_resolve, now the function works.
6347 Affected file lib/silcclient/idlist.c.
6349 * Added function silc_net_get_local_port to get local bound
6350 port by socket. Added to lib/silcutil/silcnet.[ch].
6352 * Added `sockets' and `sockets_count' fields to the SilcClient
6353 object. They hold the sockets of the listenning sockets in
6354 the client. Listenning sockets may be for example the key
6355 agreement server. Affected file lib/silcclient/client.[ch].
6356 Added functions the silc_client_add_socket and the
6357 silc_client_del_socket. They are exported to the application
6360 * Added ~./silc/clientkeys to support other client's public keys.
6362 * Renamed verify_server_key client operation to verify_public_key
6363 and added one argument to indicate the type of the connection
6364 (server, client etc.).
6366 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Added silc_server_connection_auth_request to handle the
6369 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6370 silcd/packet_receive.[ch].
6372 * Added silc_server_send_connection_auth_request into the
6373 silcd/packet_send.c to send the connection auth request packet.
6375 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6378 * Fixed the public key authentication in responder side in the
6379 server. The `auth_data' pointer includes the SilcPublicKey
6380 not the path to the public key. Affected file silcd/protocol.c.
6382 * Implemented the public key authentication in the initiator side
6383 in the server. Affected file silcd/protocol.c.
6385 * Removed the [RedirectClient] config section from the server
6386 configuration. Is not needed and I don't want to implement it.
6388 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Cleaned up the CMODE command in the server. It now works
6391 correctly and supports all the modes defined in the protocol.
6392 Affected file is silcd/command.c.
6394 * Added `hmac_name' field to the SilcChannelEntry in the server
6395 to hold the default HMAC of the channel. It can be set when
6396 creating the channel (with JOIN command). Affected files
6399 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6400 type to indicate the change of the current cipher and hmac
6401 on the channel. Client can safely ignore the <cipher> argument
6402 (if it chooses to do so) since the CHANNEL_KEY packet will
6403 force the channel key change anyway. The <hmac> argument is
6404 important since the client is responsible of setting the new
6405 HMAC and the hmac key into use.
6407 * Fixed the CMODE command in the client library as well.
6409 * Tested CMODE command in router environment successfully.
6411 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Show the version of the remote client (or server) when connecting
6414 to the server. It is logged to the log file. Affected file
6415 is silcd/protocol.c.
6417 * Fixed the KILLED notify handling in the client library. The
6418 client must be removed from all channels when receiving the
6421 Also, do not remove the client entry when giving the KILL
6422 command but when the KILLED notify is received.
6424 * Removed silc_idlist_find_client_by_nickname from the server.
6425 Not needed anymore. Affected files silcd/idlist.[ch].
6427 * Implemented the CHANNEL_CHANGE notify type handling to the
6428 server. Affected file silcd/server.c.
6432 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Added silc_server_send_notify_invite to send the INVITE
6435 notify between routers.
6437 * Implemented the INVITE command correctly to the server.
6439 * Implemented the INVITE notify type handling in the server.
6441 * Implemented the INVITE command to the client library and on the
6444 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Added function silc_server_get_client_resolve to find the
6447 client entry by ID from all ID lists and then resolve it
6448 (using WHOIS) if it cannot be found. Affected file is
6451 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * Implemented the BAN command to the client library.
6455 * The JOIN command in the server now checks the invite list
6458 * Changed the silc_command_reply_payload_encode_va and the
6459 silc_command_payload_encode_va to support that if argument is
6460 NULL it ignores and checks the next argument. Affected file
6461 lib/silccore/silccommand.c.
6463 * Added silc_server_send_notify_ban to send the BAN notify
6464 type between routers.
6466 * Chaned the silc_notify_payload_encode to support that if
6467 argument is NULL it ignores and checks the next argument.
6468 Affected file lib/silccore/silcnotify.c.
6470 * Tested ban lists in router environment successfully.
6472 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Implemented BAN command to the server, in silcd/command.[ch].
6476 * Removed the BAN and INVITE_LIST modes from the CMODE command
6479 * Added function silc_string_match to regex match two strings.
6480 Affected files lib/silcutil/silcutil.[ch].
6482 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Redefined parts of the SilcChannelEntry in the server to support
6485 the new ban and invite lists.
6487 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Redefined the INVITE command. The same command can be used to
6490 invite individuals to the channel but also to manage the invite
6491 list of the channel (to add to and remove from the invite list).
6492 Updated the protocol specs.
6494 * Added new command SILC_COMMAND_BAN that can be used to manage
6495 the ban list of the channel. Updated the protocol specs.
6497 * Removed the channel modes: the SILC_CMODE_BAN and the
6498 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6499 in the CMODE command. The equivalent features are now available
6500 using INVITE and BAN commands. Updated the protocol specs.
6502 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6503 in the network about change in the current ban list. The notify
6504 type is not used by the client.
6506 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6507 support the invite lists.
6509 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6511 * Added new function silc_string_regexify that converts string
6512 including wildcard characters into regex string that can
6513 be used by the GNU regex library. Added into the file
6514 lib/silcutil/silcutil.[ch].
6516 Added silc_string_regex_combine to combine to regex strings
6517 into one so that they can be used as one regex string by
6518 the GNU regex library. Added into the file
6519 lib/silcutil/silcutil.[ch].
6521 Added silc_string_regex_match to match two strings. It returns
6522 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6524 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Imported GNU regex to the soruce tree into lib/contrib.
6527 Fixed some compiler warning from the regex.c.
6529 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Fixed MOTD command in the server to work in router environment.
6533 * Fixed the MOTD command in the client library to support
6534 the server argument in the command.
6536 * Added `nickname_len' argument to the silc_idlist_add_client
6537 in the server, as the `nickname' argument may be binary data
6540 * Added silc_idlist_get_channels to return all channels from
6543 * Implemented LIST command to the server. Affected file is
6546 * Implemented the LIST command to the client library and on the
6549 * Added [<user count>] argument to the LIST command reply.
6550 With private channels the user count is not shown.
6552 * Updated TODO and README.
6554 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * The client entry's data.registered must be TRUE even with
6557 global client entry on global client list. The data.registered
6558 is used to check whether the client is anymore in the network,
6559 for example with WHOWAS command so it must be valid.
6561 * Fixed the WHOWAS command in the server. It now actually works
6562 in router environment. Added function into silcd/command_reply.c
6563 silc_server_command_reply_whowas_save.
6565 * Added silc_idlist_purge function to the silcd/idlist.c
6566 to periodically purge the ID Cache.
6568 * Fixed INFO command in the server. It works now in router
6569 environment. Added <server name> argument to the INFO command
6570 reply. Updated the protocol specs.
6572 * Fixed minor bug in silc_idcache_purge to not purge if the
6573 expire value is zero.
6575 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6576 they were buggy because of the WHOWAS information.
6578 * Fixed local command MSG to handle the async resolving of
6579 the remote client properly. It used to fail the first MSG.
6580 Affected file silc/local_command.c.
6582 * Added `data_len' field to SilcIDCache context.
6584 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Update TODO. Todo in commands in the server.
6588 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6591 used by routers as broadcast packet to inform other routers
6592 about the changed user mode.
6594 Implemented the notify handling in the server. Affected file is
6595 silcd/packet_receive.c. Added the function
6596 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6598 * Added new generic Channel Payload and deprecated the New Channel
6599 Payload. The New Channel Payload is now the generic Channel
6602 * Added new argument `mode' to the silc_server_send_new_channel
6603 as it is required in the Channel Payload now.
6605 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6606 and created a new and real SilChannelPayload to represent the
6607 new generic Channel Payload. Implemented the encode/decode
6608 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6610 * Added silc_server_get_client_channel_list to return the list
6611 of channels the client has joined for WHOIS command reply.
6612 Affected file silcd/server.[ch].
6614 * Implemented the channel list sending in the WHOIS command reply
6615 in server and in the client.
6617 Implemented the channel list displaying on the user interface
6618 as well. Affected file silc/client_ops.c.
6620 * Added silc_channel_payload_parse_list to parse list of Channel
6621 Payloads. It returns SilcDList list of SilcChannelPayloads.
6622 Client for example can use this function to parse the list of
6623 channels it receives in the WHOIS command reply. The caller
6624 must free the list by calling silc_channel_payload_list_free.
6625 Affected files lib/silccore/silcchannel.[ch].
6627 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Added one new argument <user mode> to the WHOIS command reply
6630 to return the mode of the user in SILC. Updated the protocol
6633 Implemented it to the server and client.
6635 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Fixed the mode printing on the user interface on joining.
6638 Affected file silc/client_ops.c.
6640 * Implemented the UMODE command and user modes in general to the
6641 client library and to the user interface.
6643 * Implemented the UMODE command to the server.
6645 * The server now sends UNKNOWN_COMMAND error status if client sends
6646 unknown command. Affected file silcd/command.c.
6648 * All server commands now handle the command identifier the right
6649 way when sending the command reply to the client. The client can
6650 use to identify the command replies with the identifier.
6652 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Added silc_server_get_client_route to resolve the route to
6655 the client indicated by the client ID. Affected file is
6658 * Added silc_server_relay_packet as general function to relay
6659 packet to arbitrary destination. This deprecates functions
6660 like _send_private_message_key, _relay_notify etc. Affected
6661 file is silcd/packet_send.[ch].
6663 Removed silc_server_send_key_agreement,
6664 silc_server_send_private_message_key and
6665 silc_server_packet_relay_notify functions from the file
6666 silcd/packet_send.[ch].
6670 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6671 server. Affected file silcd/packet_receive.[ch].
6673 * Implemented the KILL command to the client. Implemented the
6674 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6675 Affected files lib/silcclient/command[_reply].c and
6676 lib/silcclient/client_notify.c. Implemented the KILL notify
6677 printing in the user inteface.
6679 * Fixed a lot silc_parse_nick memory leaks from the client
6680 library in the file lib/silcclient/command.c.
6682 * Changed the silc_server_send_notify_on_channels's `sender'
6683 argument from SilcSocketConnection to SilcClientEntry to
6684 check the sender as entry and not as connection object and not
6685 to send to the client provided as argument. The affected file
6686 is silcd/packet_send.[ch].
6688 * The notify packets that are destined directly to the client used
6689 to not to be processed by the server. Now changed that and the
6690 server processes all notify packets. After relaying the packet
6691 to the client the notify packet is processed in the server.
6693 * The silc_server_free_client_data now checks whether there is
6694 pending outgoing traffic for the client and purges the data to
6695 the network before removing the client entry.
6697 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6699 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6700 an client is killed from the SILC Network. Updated the protocol
6703 Added new function silc_server_send_notify_killed to the
6704 silcd/packet_send.[ch].
6706 * Added function silc_server_packet_relay_notify to relay notify
6707 packets that are destined directly to a client. In this case
6708 the server does not process the notify packets but merely relays
6709 it to the client. Affected file silcd/packet_send.[ch].
6711 Added also silc_server_packet_process_relay_notify to check
6712 whereto relay the notify. Affected file is
6713 silcd/packet_receive.[ch].
6715 * Implemented the KILL command to the server.
6719 * Added the backup schema desgined last fall to the protocol
6720 specs for everyone to see. The specification is in the
6721 *-spec-xx.txt draft and the packet type definitions for the
6722 backup routers is in *-pp-xx.txt draft. Thusly, added also
6723 new packet type SILC_PACKET_CELL_ROUTERS.
6725 * A big security problem in the implementation discovered. The
6726 signoff of an client did not cause new channel key generation
6727 which it of course should've done. The channel keys must be
6728 always re-generated when client leaves (or signoffs) the channel.
6729 The silc_server_remove_from_channels funtion now handles
6730 the channel key re-generation.
6732 * Added `sender' argument to the silc_server_send_notify_on_channels
6733 to not to send the client provided as argument. Affected file
6734 silcd/packet_send.[ch].
6736 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Implemented OPER and SILCOPER commands into the server and
6741 * Added silc_auth_verify and silc_auth_verify_data to verify
6742 the authentication directly from the authentication payload.
6743 It supports verifying both passphrase and public key based
6744 authentication. Affected file lib/silccore/silcauth.[ch].
6746 * Added `hash' field to the SilcIDListData structure. It is the
6747 hash negotiated in the SKE protocol. Affected file is
6750 * Slight redesigning of the SilcAuthPayload handling routines.
6751 Do not send SilcPKCS but SilcPublicKey as argument.
6753 * Implemented the public key authentication support to the
6754 serverconfig. The public key is loaded from the provided path
6755 and saved as authentication data to void * pointer. Thus,
6756 changed the unsigned char *auth_data to void *auth_data;
6758 * Fixed SHUTDOWN command to send the reply before the server
6759 is shutdown. :) Affected file silcd/command.c.
6761 * Fixed fatal bug in CONNECT command. The hostname was invalid
6762 memory and server crashed. Affected file silcd/command.c.
6764 * Fixed fatal bug in CLOSE command. The server_entry became
6765 invalid but was referenced later in the command. Affected file
6768 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Fixed fatal bug in failure packet handling. Server ignored
6771 the failure and thus crashed when it came.
6775 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6777 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6778 that the command may be executed only once in (about) 2 seconds.
6779 The old SILC_CF_LAG flag is same but allows command bursts up
6780 to five before limiting.
6782 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6783 server code. Various commands now includes the CF_LAG_STRICT
6784 flag to disallow any kind of miss-use of the command.
6786 * Fixed the silc_buffer_unformat to not to allocate any data
6787 if the length of the data is zero. It used to allocate the
6788 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6790 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Changed the format of AdminConnection configuration section
6793 in the server. Added username of the admin to the format.
6794 Affected files silcd/serverconfig.[ch].
6796 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6797 to return admin configuration data by host, username and/or
6800 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Implemented WHOWAS command to the server. Added the functions:
6804 silc_server_command_whowas_parse,
6805 silc_server_command_whowas_send_reply,
6806 silc_server_command_whowas_from_client and
6807 silc_server_command_whowas_from_server
6809 * Added <Client ID> argument to the WHOWAS command reply. Updated
6810 the protocol specs accordingly.
6812 * Implemented WHOWAS command and command_reply to the client
6815 Implemented the WHOWAS printing on the user interface.
6817 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Added new argument to the WHOWAS command reply, the real name.
6820 It is an optional argument. Updated the protocol specs.
6822 * Added SilcIDCacheDestructor callback that is registered when
6823 the SilcIDCache is allocated. The callback is called when
6824 an cache entry in the ID Cache expires, or is purged from the
6825 cache. Added into lib/silccore/idcache.[ch].
6827 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6828 to destruct the client entries when the cache entry expires.
6829 Other ID Cache's in server and in the client library ignores
6832 * If the ID Cache entry's `expire' field is zero then the entry
6833 never expires. Added boolean `expire' argument to the
6834 silc_idcache_add function in the lib/silccore/idcache.[ch].
6835 If it is TRUE the default expiry value is used.
6837 * Added silc_server_free_client_data_timeout that is registered
6838 when client disconnects. By default for 5 minutes we preserve
6839 the client entry for history - for WHOWAS command.
6841 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Added support to the server to enforce that commands are not
6844 executed more than once in 2 seconds. If server receives
6845 commands from client more frequently, timeout is registered
6846 to process the commands. Affected file silcd/command.c.
6847 Added new function silc_server_command_process_timeout.
6849 * Changed NICK_NOTIFY handling in client library to check that
6850 if the client's nickname was changed, so there is no need to
6851 resolve anything from the server.
6853 * Removed error printing from the WHOIS and IDENTIFY commands.
6854 If error occurs then it is ignored silently in the client library.
6855 The application, however, may map the received error to
6856 human readable error string. The application currently maps
6857 the NO_SUCH_NICKNAME error to string.
6859 * Made the command status message public to the application. Moved
6860 them from lib/silcclient/command_reply.c to
6861 lib/silcclient/command_reply.h. The application can map the
6862 received command status to the string with the
6863 silc_client_command_status_message function.
6865 * Added check to the server to check that client's ID is same
6866 as the Source ID in the packet the client sent. They must
6869 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Added dist-bzip hook to the Makefile.am to make bzip2
6872 compressed distributions.
6874 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Server now enforces the maximum length for the nickname and
6877 the channel as protocol specification dictates. 128 bytes for
6878 nickname and 256 bytes for channel name.
6880 * Moved the WHOIS printing to the application. The client libary
6881 does not print out the WHOIS information anymore, the application
6882 must do it. Renamed silc_client_command_reply_whois_print to
6883 the silc_client_command_reply_whois_save.
6885 The client's idle time is also sent to the application now, and
6886 the idle is shown on screen.
6888 * Added silc_client_command_reply_identify_save to save the
6889 received IDENTIFY entries.
6891 * Do not check for channel private keys in message sending and
6892 reception if the channel does not have the PRIVKEY mode set.
6893 Affected file lib/silclient/client_channel.c.
6895 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6898 just surfaced after chaning the JOIN procedure.
6900 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Added silc_client_get_clients_by_list to get client entries
6903 from Client ID list, that is returned for example by JOIN
6904 and USERS command replies. The application should use this
6905 function for example when JOIN command reply is received to
6906 resolve the clients already on the channel (library does not
6907 do that anymore as USERS command reply is not used in the JOIN
6908 procedure anymore). Affected files lib/silcclient/silcapi.h and
6909 lib/silcclient/idlist.c.
6911 * JOIN command reply and USERS command reply returns now SilcBuffer
6912 pointers instead of unsigned char pointers when returning
6913 the client list and mode list.
6915 * Added <Client ID> argument to the JOIN command reply, mainly
6916 for the server to identify for which client the command was
6917 originally sent. Updated protocol specs accordingly.
6919 * Added SilcDlist private_key pointer to the SilcChannelEntry
6920 in the client to support the channel private keys. Affected
6921 file is lib/silcclient/idlist.h.
6923 * Added SilcChannelPrivateKey argument to the function
6924 silc_client_send_channel_message so that application can choose
6925 to use specific private ke if it wants to. If it is not provided,
6926 the normal channel key is used, unless private keys are set.
6927 In this case the first (key that was added first) is used
6928 as the encryption key.
6930 * Implemented the support for channel private key handling.
6931 Implemented the following functions:
6933 silc_client_add_channel_private_key,
6934 silc_client_del_channel_private_keys,
6935 silc_client_del_channel_private_key,
6936 silc_client_list_channel_private_keys and
6937 silc_client_free_channel_private_keys
6939 Affected file lib/silcclient/client_channel.c.
6941 * Added the support for the private keys in the channel message
6942 sending and encryption and in the message reception and
6943 decryption. Affected funtions are
6944 silc_client_send_channel_message and silc_client_channel_message.
6946 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Added SKE's key verify callback to the client library's
6949 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6951 * Removed the statement that server (or router) must send USERS
6952 command reply when joining to the channel so that the client
6953 knows who are on the channel. Instead, the client list and
6954 client's mode list is now sent in the JOIN command reply to the
6955 client who joined channel. This is better solution.
6957 * Added function silc_server_get_users_on_channel and function
6958 silc_server_save_users_on_channel to the silcd/server.[ch].
6960 * Removed function silc_server_command_send_users from the
6963 * Do not show topic on the client library anymore. The topic is
6964 sent in the command reply notify to the application and the
6965 application must show the topic now.
6967 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6969 * Added client searching by nickname hash into the IDENTIFY and
6970 WHOIS commands in the server as they were clearly missing from
6971 them. Affected file is silcd/command.c.
6973 * Fixed a bug in private message receiving in the client library.
6974 The remote ID was freed and it wasn't supposed, now it is
6977 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Minor fix to the channel payload; allocate the data area, as it
6980 needs to be of specific length.
6982 * If the key agreement port is zero then the operating
6983 system will define the bound port. Affected files are
6984 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6986 * Added new function silc_channel_payload_decrypt into the file
6987 lib/silccore/silcchannel.[ch].
6989 * Moved the channel message etc, check from silc_packet_decrypt
6990 to applications. The library calls now a generic
6991 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6992 when the packet is either normal or special. This was done to
6993 allow more wide range of checking that was not allowed when
6994 the code was in library. Now applications can do virtually any
6995 checks to the packet and return to the library the decision how
6996 the packet should be processed. Affected files are
6997 lib/silccore/silcpacket.[ch].
6999 Added silc_server_packet_decrypt_check to the server and
7000 silc_client_packet_decrypt_check to the client library.
7002 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7003 to send with specified source and destination information.
7005 * Channel message delivery between routers was broken after the
7006 channel key distribution was fixed earlier. The channel key
7007 was used be to distributed to other routers as well which is not
7008 allowed by the protocol. Now this is fixed and channel keys
7009 really are cell specific and the channel message delivery between
7010 routers comply with the protocol specification.
7012 * Fixed various commands in server to check also the global list
7013 for the channel entry and not just the local list. The affected
7014 file silcd/command.c.
7016 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Added assert()s to buffer formatting and unformatting routines
7019 to assert (if --enable-debug) when error occurs. Affected
7020 file: lib/silcutil/silcbuffmt.c.
7022 * Changed to auto-reconnect to check whether the remote host is
7023 router and register the re-connect timeout if it is. It used
7024 to check that whether we are normal server, but router must do
7025 auto-reconnect with another router as well. Affected file
7028 * Removed the [<key len>] option from CMODE command as the cipher
7029 name decides the key length, nowadays. See the defined ciphers
7030 from the protocol specification.
7032 * Added [<hmac>] option to the CMODE command to define the HMAC
7033 for the channel. Added SILC_CMODE_HMAC channel mode.
7035 * Added [<hmac>] option for the JOIN command so that user can
7036 select which HMAC is used to compute the MACs of the channel
7039 * Added Hmac field to the Channel Message Payload. The integrity
7040 of plaintext channel messages are now protected by computing
7041 MAC of the message and attaching the MAC to the payload. The
7042 MAC is encrypted. Now, it is clear that this causes some
7043 overhead to the size of the packet but rationale for this is that
7044 now the receiver can verify whether the channel message decrypted
7045 correctly and also when private keys are set for the channel the
7046 receiver can decrypt the packet with several keys and check from
7047 the MAC which key decrypted the message correctly.
7049 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7050 lib/silccrypt/silccipher.[ch].
7052 * Added silc_hash_len to return the digest length into the
7053 lib/silcrypt/silchash.[ch].
7055 * Rewrote parts of Silc Channel Payload interface in the
7056 lib/silccore/silcchannel.[ch]. The encode function now also
7057 encrypts the packet and parse function decrypts it.
7059 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Fixed a minor formatting bug in the SKE's key material processing.
7062 It actually might have processed the keys wrong way resulting
7065 * Redefined the mandatory HMAC algorithms and added new algorithms.
7066 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7067 and hmac-md5 truncated to 96 bits. The mandatory is now
7068 hmac-sha1-96. Rest are optional (including the one that used
7069 to be mandatory). Rationale for this is that the truncated HMAC
7070 length is sufficient from security point of view and can actually
7071 make the attack against the HMAC harder. Also, the truncated
7072 HMAC causes less overhead to the packets. See the RFC2104 for
7075 * Added new [hmac] configuration section. The SKE used to use
7076 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7077 is of course wrong. The official names that must be proposed in
7078 the SKE are the ones defined in the protocol specification
7079 (hmac-sha1-96 for example). The user can configure any hmac
7080 using any hash function configured in the [hash] section. At
7081 least, the mandatory must be configured.
7083 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7085 * Added HMAC list to the SKE proposal list. It has now both
7086 hash algorithm list and HMAC list. This makes the protocol
7087 incompatible with previous versions. The SKE now seems to work
7088 the way it is supposed to work, for the first time actually.
7090 * Defined plain Hash algorithms to the protocol specification.
7093 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7095 * Implemented support for key agreement packets into the server.
7096 Added functions silc_server_key_agreement and
7097 silc_server_send_key_agreement. Other than these functions,
7098 server has nothing to do with this packet.
7100 * Added support for private message key packets into the server.
7101 Added functions silc_server_private_message_key and
7102 silc_server_send_private_message_key.
7106 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7107 called in the protocol's final callback instead in the END
7108 protocol state. This makes a little more sense and in the same
7109 time in client we can use the same protocol routines for normal
7110 key exchange and to key agreement packet handling as well.
7112 * Added to both client's and server's KE protocol context the
7113 SilcSKEKeyMaterial pointer to save the key material. We will
7114 bring the key material to the protocol's final callback by doing
7115 this. The final callback must free the key material.
7117 * Added SKE's packet_send callback into client's KE protocol
7118 context so that the caller can choose what packet sending function
7119 is used. This way we can use different packet sending when
7120 doing normal SKE when doing key agreement packet handling (in
7121 the key agreement packet handling we do not want to encrypt
7124 * Implemented the responder side of the key agreement routines
7125 in the client. The client can now bind to specified port and
7126 accept incoming key negotiation. The key material is passed
7127 to the application after the protocol is over.
7129 * Implemented the processing of incoming Key Agreement packet
7130 in the client. Added function silc_client_key_agreement to
7133 * Implemented the intiator side of the key agreement routines
7134 in the client. The client can now initiate key agreement with
7135 another remote client. The key material is passed to the
7136 application after the protocol is over.
7138 * Created client_keyagr.c to include all the key agreement
7141 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7142 SILC_TASK_CALLBACK except that it is not static.
7144 * Created client_notify.c and moved the Notify packet handling
7145 from the client.[ch] into that file.
7147 * Created client_prvmsg.c and moved all private message and
7148 private message key routines from the client.[ch] into that file.
7150 * Create client_channel.c and moved all channel message and
7151 channel private key routines from the client.[ch] into that file.
7153 * Changed silc_client_get_client_by_id_resolve to resolve with
7154 WHOIS command instead of IDENTIFY command, in the file
7155 lib/silclient/idlist.c.
7157 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * Implemented the SKE's responder side to the Client library.
7161 * When FAILURE is received to the protocol do not trust it
7162 blindly. Register a timeout to wait whether the remote closes
7163 the connection as it should do it, only after that process the
7164 actual failure. This was changed to both client and server.
7166 * Added client_internal.h to include some of the structures
7167 there instead of client.h in lib/silcclient/.
7169 * Added function silc_task_unregister_by_callback to unregister
7170 timeouts by the callback function.
7172 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7174 * Some "Incomplete WHOIS info" errors has been appearing on the
7175 log files. Took away the entry->userinfo check from WHOIS
7176 reply sending. The entry->userinfo is now " " if client did not
7177 provide one. I thought this was fixed earlier but something
7178 is wrong still. Let's see if the error still appears.
7180 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7182 * Fixed a minor bug in the login when the channel key is
7183 re-generated in the server. It used to generate the key in
7184 wrong order and thus caused problems in the channel traffic.
7186 * Fixed a minor bug in channel key distsribution after
7187 KICK command. The key was not sent to the router even though
7190 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7192 * Added silc_ske_process_key_material_data as generic routine
7193 to process any key material as the SILC protocol dictates. The
7194 function is used by the actual SKE library but can be used by
7195 applications as well. This relates to the private message keys
7196 and the channel private keys since they must be processed the
7197 same way the normal SILC session keys. The protocol dictates
7198 this. Affected files: lib/silcske/silcske.[ch].
7200 Added also silc_ske_free_key_material to free the
7201 SilcSKEKeyMaterial structure.
7203 * Defined silc_cipher_set_key function to set the key for
7204 cipher without using the object's method function. The affected
7205 files: lib/silccrypt/silccipher.[ch].
7207 * Implemented silc silc_client_add_private_message_key,
7208 silc_client_add_private_message_key_ske,
7209 silc_client_del_private_message_key,
7210 silc_client_list_private_message_keys and
7211 silc_client_free_private_message_keys functions in the
7214 Added functions silc_client_send_private_message_key to send
7215 the Private Message Key payload and silc_client_private_message_key
7216 to handle incoming Private Message Key payload.
7218 * Added Cipher field to the Private Message Key payload to set
7219 the cipher to be used. If ignored, the default cipher defined
7220 in the SILC protocol (aes-256-cbc) is used.
7222 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7224 * Removed lib/silcclient/ops.h file.
7226 Redefined parts of the SILC Client Library API. Created new
7227 file silcapi.h that deprecates the ops.h file and defines the
7228 published Client Library API. Defined also private message key
7229 API and channel private key API into the file.
7231 This is the file that the application must include from the
7232 SILC Client Library. Other files need not be included by
7233 the application anymore.
7235 * Added new key_agreement client operation callback and also
7236 defined the Key Agreement library API for the application.
7238 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7241 is used by clients to request key negotiation between another
7242 client in the SILC network. If the negotiation is started it
7243 is performed using the SKE protocol. The result of the
7244 negotiation, the secret key material, can be used for example
7245 as private message key.
7247 Implemented the Key Agreement payload into the files
7248 lib/silccore/silauth.[ch].
7250 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7252 * Redefined ciphers for the SILC protocol. Added some new ciphers
7253 and defined the key lengths for the algorithms. Changed the
7254 code accordingly. The default key length is now 256 bits.
7256 * Fixed SKE key distribution function silc_ske_process_key_material
7257 when the key length is more than 128 bits. The default key
7258 length in SILC is now 256 bits.
7260 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7261 to indicate unsupported algorithm.
7263 * Renamed rijndael.c to aes.c and all functions as well.
7265 * Fixed a long standing channel key setting bug in client library.
7266 Weird that it has never surfaced before.
7268 * Fixed bug in channel deletion. If the entire channel is removed
7269 then it must also delete the references of the channel entry
7270 from the client's channel list as the client's channel entry and
7271 the channel's client entry share same memory.
7273 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * Implemented CONNECT and SHUTDOWN commands in the client.
7277 * Implemented CLOSE command to the client.
7279 * Added the function silc_idlist_find_server_by_name into the
7280 files silcd/idlist.[ch].
7282 Added the function silc_idlist_find_server_by_conn into the
7283 files silcd/idlist.[ch].
7285 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7287 * DIE command was renamed to SHUTDOWN. Updated the both code
7290 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7291 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7293 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7296 * Added function silc_server_create_connection function to create
7297 connection to remote router. My server implementation actually
7298 does not allow router to connect to normal server (it expects
7299 that normal server always initiates the connection to the router)
7300 so the CONNECT command is only good for connecting to another
7303 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7306 or some other client was kicked from the channel.
7308 Implemented the handling of the notify type to both client
7311 Implemented silc_server_send_notify_kicked to send the KICKED
7312 notify. It is used to send it to the server's primary router.
7314 * Implemented the KICK command into server and client.
7316 * Added `query' argument to the silc_idlist_get_client function
7317 to indicate whether to query the client from server or not if
7320 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7321 to indicate that the client is not channel founder.
7325 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Removed the rng context from SilcPacketContext structure and
7328 changed that the packet routine uses the Global RNG API.
7330 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Added support for quit message that client can "leave" on the
7333 channel when it quits the SILC. It is ditributed inside the
7334 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7336 Added silc_server_free_client_data that will take the
7337 signoff message as argument.
7339 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7341 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Updated parts of the protocol specification to keep it up
7346 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7349 payloads in one packet.
7351 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7352 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7353 use now the new List flag.
7355 * Also deprecated the following packet types: REPLACE_ID,
7356 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7358 * Added list support for Notify packet in server.
7360 * Added silc_server_send_notify_channel_change to send the
7361 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7362 the silc_server_send_replace_id.
7364 * Added silc_server_send_notify_nick_change to send the
7365 NICK_CHANGE notify type. Deprecates the function
7366 silc_server_send_replace_id.
7368 * Added silc_server_send_notify_join to send the JOIN notify type.
7369 Deprecates the function silc_server_send_new_channel_user.
7371 * Added silc_server_send_notify_leave to send LEAVE notify type.
7372 Deprecates the function silc_server_send_remove_channel_user.
7374 * Added silc_server_send_notify_cmode and
7375 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7376 types. Deprecates the silc_server_send_set_mode function.
7378 * Added SERVER_SIGNOFF notify type to indicate that server has
7379 quit. This means that all clients on the channel from that
7380 server will drop. This can be also used when netsplit happens.
7382 Deprecated REMOVE_ID packet type since it is not needed anymore
7385 Added silc_server_send_notify_server_signoff to send the
7386 SERVER_SIGNOFF notify type. Deprecates the function
7387 silc_server_send_remove_id.
7389 Added also silc_server_send_notify_signoff to send the
7390 SIGNOFF notify type.
7392 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7393 SILC protocol from this day on. Changed the protocol
7394 specification as well.
7396 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7397 notify type. It is used between routers to notify about
7398 topic changes on a channel.
7400 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7403 * Partly updated the protocol specification to comply with the
7404 changes now made. It is still though a bit outdated.
7406 * The JOIN notify type now takes one extra argument <Channel ID>.
7407 The packet used to be destined to the channel but now the
7408 JOIN type may be sent as list thus it is impossible to
7409 destine it to any specific channel. By adding this argument
7410 it is again possible.
7412 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * Added CREDITS file. The CHANGES and CREDITS file will appear
7415 in the distribution as well.
7417 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7420 types in the server's silcd/packet_receive.c.
7422 * Implemented CMODE and CUMODE to work in router environment.
7424 * Fixed minor encoding and decoding buglet from the
7425 lib/silccore/silcmode.c.
7427 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7430 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7432 * Changed all SilcConfigServer* and silc_config_server* to
7433 SilcServerConfig* and silc_server_config*, respectively.
7436 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7438 * Associated the ID (client or server ID) to the Authentication
7439 Payload to avoid any possibility of forging. Updated the
7440 protocol specification and the code accordingly.
7442 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * The RSA key length is now save to the RsaKey context in the
7445 key generation process in lib/silccrypt/rsa.c. The key length
7446 is now used to figure out the maximum size of the block allowed
7447 to be encrypted/signed.
7449 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7450 is equivalent to the silc_mp_mp2bin but does not allocate any
7453 * Changed silc_mp_mp2bin API to take length argument. If it is
7454 non-zero then the buffer is allocated that large. If zero, then
7455 the size is approximated using silc_mp_sizeinbase, which however
7458 * Created Global RNG API which is global RNG that application can
7459 initialize. After initializing, any routine anywhere in the
7460 code (including library) can use RNG without allocating a new
7461 RNG object. This was done to allow this sort of use of the
7462 RNG in code that has no chance to allocate RNG object. All
7463 applications currently allocate this and many routines in the
7464 library use this. Affected file lib/silccrypt/silcrng.[ch].
7466 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7467 it to use the Global RNG API.
7469 * Defined Authentication Payload into protocol specification that
7470 is used during SILC session to authenticate entities. It is
7471 used for example by client to authenticate itself to the server
7472 to obtain server operator privileges.
7474 Implemented this payload into the lib/silccore/silcauth.[ch].
7475 Implemented also routines for public key based authentication
7476 as the new protocol specification dictates.
7478 Moved definitions of different authentication methods from
7479 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7481 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7482 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7483 silc_pkcs_verify_with_hash functions into the file
7484 lib/silccrypt/silcpkcs.[ch].
7486 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * The client entry's userinfo pointer must be always valid.
7489 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7490 will fail since it requires the userinfo. Now, the userinfo
7491 is allocated as "" if actual userinfo does not exist. Actually,
7492 it must exist and it is totally Ok to drop client connections
7493 that does not announce the userinfo. However, we will make
7494 this workaround for now.
7496 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7497 to return the remote port by socket.
7499 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7501 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7502 SILC_SERVER_PENDING_EXEC and added an new macro
7503 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7504 data or when error occurs while processing the pending command.
7506 Added new argument `destructor' into silc_server_command_pending
7507 and to the SilcServerCommandPending object. This destructor is
7508 now called after calling the pending callback or if error occurs
7509 immediately. If error occurs the actual pending callback won't
7510 be called at all - only the destructor. The destructor may be
7511 NULL if destructor is not needed.
7513 All this applies for client library code as well. Similar
7514 changes were made there as well for the pending commands.
7516 In the client, the application must now allocate the
7517 SilcClientCommandContext with the silc_client_command_alloc
7520 * Added reference counter to the SilcServerCommandContext. Added
7521 function silc_server_command_alloc and silc_server_command_dup
7524 Same type of functions added to the client library for the same
7527 * Removed the cmd_ident from IDListData away since it is now
7528 global for all connections. It is the command identifier used
7529 in command sending and with pending commands. The affected file
7532 * Added reference counter to the SilcSocketConnection objecet to
7533 indicate the usage count of the object. The object won't be
7534 freed untill the reference counter hits zero. Currently only
7535 server uses this, and client ignores it. The client must be
7536 set to use this too later. The affected files are
7537 lib/silccore/silcsockconn.[ch]. Added also the function
7538 silc_socket_dup to increase the reference counter.
7540 This was mainly added because it is possible that the socket
7541 is removed underneath of pending command or other async
7542 operation. Now it won't be free'd and proper DISCONNECTING
7543 flags, etc. can be set to avoid sending data to connection that
7544 is not valid anymore.
7546 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7547 the connection. After that it sets SILC_SET_DISCONNECTED.
7548 It is, however, possible that the socket data is not still freed.
7549 The silc_server_packet_process now checks that data is not
7550 read or written to connection that is DISCONNECTED. The socket
7551 get's freed when the reference counter hits zero.
7553 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7555 * Changed the client operation API: channel_message operation's
7556 `sender' is now the client entry of the sender, not the nickname
7557 and the `channel' is the channel entry, not the channel name.
7559 In the private_message operation the `sender' is now also the
7560 client entry of the sender not the nickname.
7562 Affected file is lib/silcclient/ops.h and all applications
7563 using the client operations.
7565 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7567 * Moved the calling of ops->connect() from connect_to_server_final
7568 into receive_new_id functin since that is the point when the
7569 client is actually allowed to send traffic to network. The
7570 affected file is lib/silcclient/client.c.
7572 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7574 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7575 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7576 (if needs broadcasting) instead of broadcasting the packets one
7577 by one which would make a burst in the network traffic.
7579 * Added `broadcast' argument to the functions in silcd/server.[ch]
7580 silc_server_create_new_channel[_with_id] to indicate whether
7581 to send New Channel packet to primary router.
7583 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7585 * Added new function into the silcd/server.[ch] files:
7586 silc_server_create_new_channel_with_id to create new channel with
7587 already existing Channel ID.
7589 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7590 lib/silccore/silcpacket.h. This packet is used t send list of
7591 Set Mode payloads inside one packet. Server uses this to set
7592 the modes for the channels and clients on those channels, that it
7593 announced to the router when it connected to it. The protocol
7594 specification has been updated accordingly.
7596 * The silc_server_new_channel did not handle the packet coming
7597 from normal server as it normally does not send that. However,
7598 when it announces its channels it does send it. Implemented
7599 the support for that.
7601 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7602 into the file lib/silccore/id.h.
7604 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Fixed memory leaks in the functions silc_idlist_del_client,
7607 silc_idlist_del_channel and silc_idlist_del_server in the file
7608 silcd/idlist.c. All of those leaked like a sieve.
7610 * Fixed some small memory leaks in the client's function
7611 silc_client_notify_by_server.
7613 * Added functions into silcd/server.c: silc_server_announce_clients,
7614 silc_server_announce_channels and silc_server_announce_server.
7615 These functions are used by normal and router server to announce
7616 to its primary router about clients, channels and servers (when
7617 router) that we own. This is done after we've connected to the
7620 These functions effectively implements the following packet types:
7621 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7622 and SILC_PACKET_NEW_ID_LIST.
7624 * Added new functions into the silcd/packet_receive.[ch]:
7625 silc_server_new_id_list, silc_server_new_channel_list and
7626 silc_server_new_channel_user_list to handle the incoming
7627 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7629 * Added support of changing Channel ID in the function
7630 silc_server_replace_id. If the server that announces a channel
7631 to the router already exists in the router (with same name but
7632 with different Channel ID), router is responsible to send
7633 Replace ID packet to the server and force the server to change
7634 the Channel ID to the one router has.
7636 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7637 client that the Channel ID has been changed by the router. The
7638 normal server sends this to the client. Client must start using
7639 the new Channel ID as the channel's ID.
7641 Implemented handling of this new type into lib/silcclient/client.c
7642 into the function silc_client_notify_by_server.
7644 * Added new function silc_idlist_replace_channel_id into the files
7645 silcd/idlist.[ch] to replace the Channel ID.
7647 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7649 * Call silc_server_command_identify_check always when processing
7650 the IDENTIFY command in silcd/command.c
7652 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7654 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7655 send keepalive packets. The packet can be sent by clients,
7656 servers and routers.
7658 Added function silc_socket_set_heartbeat into the file
7659 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7660 If not set, the heartbeat is not performed. The actual
7661 heartbeat is implemented in the low level socket connection
7662 library. However, application is responsible of actually
7665 Added silc_server_send_heartbeat to send the actual heartbeat
7666 packet into silcd/packet_send.[ch]. Server now performs
7667 keepalive with all connections.
7669 * Added silc_task_get_first function into lib/silcutil/silctask.c
7670 to return the timeout task with shortest timeout. There was a bug
7671 in task unregistration that caused problems. TODO has been
7672 updated to include that task system must be rewritten.
7674 * The client library will now resolve the client information when
7675 receiving JOIN notify from server for client that we know but
7676 have incomplete information.
7678 * Rewrote parts of silc_server_remove_from_channels and
7679 silc_server_remove_from_one_channel as they did not remove the
7680 channel in some circumstances even though they should've.
7682 * Encryption problem encountered in server:
7684 The LEAVE command used to send the Channel Key packet to the
7685 router immediately after generating it. However, the code
7686 had earlier sent Remove Channel user packet but not immediately,
7687 ie. it was put to queue. The order of packets in the router
7688 was that Channel Key packet was first and Remove Channel User
7689 packet was second, even though they were encrypted in the
7690 reverse order. For this reason, MAC check failed. Now, this
7691 is fixed by not sending the Channel Key packet immediately but
7692 putting it to queue. However, this is more fundamental problem:
7693 packets that are in queue should actually not be encrypted
7694 because packets that are sent immediately gets encrypted
7695 actually with wrong IV (and thus MAC check fails). So, packets
7696 that are in queue should be encrypted when they are sent to
7697 the wire and not when they put to the queue.
7699 However, the problem is that the current system has not been
7700 designed to work that way. Instead, the packet is encrypted
7701 as soon as possible and left to the queue. The queue is then
7702 just purged into wire. There won't be any fixes for this
7703 any time soon. So, the current semantic for packet sending
7706 o If you send packet to remote host and do not force the send
7707 (the packet will be in queue) then all subsequent packets to the
7708 same remote host must also be put to the queue. Only after the
7709 queue has been purged is it safe again to force the packet
7712 o If you send all packets immediately then it safe to send
7713 any of subsequent packets through the queue, however, after
7714 the first packet is put to queue then any subsequent packets
7715 must also be put to the queue.
7717 Follow these rules and everything works fine.
7719 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7721 * Added new function silc_server_remove_clients_by_server to
7722 remove all client entries from ID list when the server connection
7723 is lost. In this case it is also important to invalidate all
7724 client entires as they hold the invalid server entry. This
7725 fixes fatal bug when server has lost connection and will reconnect
7728 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Made some sanity checks to silc_server_daemonise like to check
7731 whether the requested user and group actually exists.
7733 * Added sanity check to SKE's silc_ske_responder_finish to check
7734 that the public and private key actually is valid.
7736 * Invalidate the client's nickname when receiving Replace ID
7737 packet and the Client ID is being replaced. This means that the
7738 server will query the nickname if someone needs it (client)
7741 * Sort the ID Cache in client library when the ID Cache data
7742 has changed (needs sorting).
7744 * Do not allow for SILC client to create several connections to
7745 several servers. The client does not support windows right now
7746 and generating multiple connections causes weird behaviour.
7748 Irssi-silc client does support windows and can handle several
7749 connections without problems, see: www.irssi.org and SILC plugin.
7751 * Fixed some places where client was added to the IDList. The
7752 rule of thumb is following (in order to get everything right):
7753 If the client is directly connected local client then the
7754 `connection' argument must be set and `router' argument must be
7755 NULL to silc_idlist_add_client function. If the client is not
7756 directly connected client then the `router' argument must
7757 bet set and the `connection' argument must be NULL to the
7758 silc_idlist_add_client function.
7760 * The funtion silc_server_packet_send_local_channel actually did
7761 not check whether the client was locally connected or not. It
7762 does that now. Fixed a bug related to LEAVE command.
7764 * Fixed Remove Channel User payload parsing bug in server's
7765 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7767 * The server's silc_server_save_channel_key now checks also the
7768 global ID list for the channel as it might not be in the local
7769 list. Fixed a bug related to LEAVE command.
7771 * Is this the end of the [<unknown>] buglet that has been lurking
7772 around for a long time? A little for loop fix in server's
7773 silc_server_command_whois_parse that is used by both IDENTIFY
7774 and WHOIS command. At least, this was a clear bug and a cause
7775 of one type of [<unknown>] buglet.
7777 * WHOIS and IDENTIFY commands call the function
7778 silc_server_command_[whois/identify]_check function even if
7779 we are not router server.
7781 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7783 * Added --with-gmp configuration option. If set the GMP
7784 is always compiled in the SILC source tree. If not set then
7785 it is checked whether the system has the GMP3 installed. If
7786 it has then the GMP won't be compiled (the system's headers
7787 and library is used), if it doesn't have it then the GMP is
7788 compiled in the SILC source tree.
7790 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Changed RSA private exponent generation to what PKCS #1
7793 suggests. We try to find the smallest possible d by doing
7794 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7795 not security fix but optimization.
7797 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Added new config entry [Identity] to fork the server and run
7800 it as specific user and group. A patch from Bostik.
7802 * Imported Dotconf configuration library into lib/dotconf.
7803 This will be used to create the SILC configuration files later.
7804 It will appear in the distsribution after this commit.
7806 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7808 * A big code auditing weekend happening. Auditing code for
7809 obvious mistakes, bugs and errors. Also, removing any code
7812 Removed files for being obsolete:
7814 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7815 inline in the file lib/silcutil/silcbuffer.h)
7817 o lib/silcutil/silcbufutil.c (the header has inline versions)
7819 Changed code to fix possible error conditions:
7821 o The buffer formatting routines now check that the destination
7822 buffer really has enough space to add the data. This applies for
7823 both buffer formatting and unformatting
7824 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7825 unformatting was changed to accomodate following rules:
7826 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7827 sent to the function while XXX_*STRING will not allocate or copy
7828 the data into the buffer. Instead it sets the pointer from the
7829 buffer into the pointer sent as argument (XXX_*STRING used to
7830 require that the pointer must be allocated already). This change
7831 makes this whole thing a bit more consistent and more optimized
7832 (note that the data returned in the unformatting with XXX_*STRING
7833 must not be freed now). The routines return now -1 on error.
7835 o Tried to find all code that use buffer_format and buffer_unformat
7836 and added return value checking to prevent formatting and
7837 especially unformatting errors and possible subsequent fatal
7840 o Changed ske->x and ske->KEY to mallocated pointers in
7841 lib/silcske/silcske.h. Fixed possible data and memory leak.
7843 o Added return value checking to all *_parse* functions. Fixed
7844 many memory leaks as well.
7846 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7847 so that buffer overflows would not happen. All code now also
7848 checks the return value as it can fail.
7850 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7852 * Added reconnection support to server if the normal server looses
7853 its connection to the router (for example if router is rebooted).
7854 The server performs normal reconnection strategy implemented
7855 to the server. Affected file silcd/server.c.
7857 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7859 * Added new packet type SILC_PACKET_SET_MODE that is used to
7860 distribute the information about changed modes (for clients,
7861 channels and clients channel modes) to all routers in the
7862 network. Updated the protocol specification accordingly.
7864 Added functions into silcd/packet_send.c and
7865 silcd/packet_receive.c: silc_server_send_set_mode,
7866 silc_server_set_mode.
7868 Added new files silcmode.[ch] into lib/silccore that implements
7869 the encoding and decoding of Set Mode Payload. Added new type
7870 SilcSetModePayload. Moved the definitions of different modes
7871 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7873 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7875 * Oops, a little mistake in server's connection authentication
7876 protocol. The protocol is not ended with FAILURE but with
7877 SUCCESS if the authentication is Ok. :) Affected file is
7880 * Implemented NICK_CHANGE notify handling in server in the file
7881 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7882 the local clients on the channel. After the changing nickname
7883 in router environment snhould work and the [<unknown>] nickname
7884 should appear no more.
7886 The silc_server_replace_id function that receives the Replace ID
7887 payload now sends the NICK_CHANGE notify type also in the file
7888 silcd/packet_receive.c
7890 * Changed WHOIS and IDENTIFY command to support the maximum amount
7891 of arguments defined in protocol specs (3328 arguments). This
7892 fixed a bug that caused problems when there were more than three
7895 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Added extra parameter, command identifier, to the
7898 silc_client_send_command so that explicit command identifier
7901 Changed that ID list routines uses specific command identifier
7902 when sending WHOIS/IDENTIFY requests to the server so that they
7903 can be identified when the reply comes back.
7905 Affected files lib/silcclient/command.[ch],
7906 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7908 * Added `sender' argument to silc_server_packet_send_to_channel
7909 to indicaet the sender who originally sent the packet to us
7910 that we are now re-sending. Ignored if NULL. Affected file
7911 silcd/packet_send.[ch].
7913 * Added some server statistics support in silcd/server_internal.h
7914 SilcServerStatistics structure and around the server code. Also
7915 send some nice statistics information when client is connecting
7918 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7920 * Fixed channel ID decoding in server's JOIN command reply in
7921 silcd/command_reply.c
7923 * Fixed braodcasting of replace ID payload to not to send it if
7924 we are standalone server in silcd/packet_receive.c.
7926 * Fixed all channel message sending routines to not to send
7927 packets to clients that has router set, since they are routed
7928 separately in the same function earlier. Affects file
7929 silcd/packet_send.c and all channel packet sending functions.
7931 * In USERS reply, res_argv[i] are not allocated, the table
7932 is allocated. Thus changed that free the table, not its
7935 * In server's whois_check and identify_check if the client is
7936 locally connected do not send any WHOIS commands - they are not
7939 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7941 * Fixed some minor bugs in client when sending WHOIS command. The
7942 arguments was in wrong order.
7944 * Removed statis function add_to_channel from server in
7945 silcd/command.c that was previously used with the joining but
7948 * Tested USERS command in router environment successfully with two
7949 routers, two servers and two clients.
7951 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7953 * Reorganized the USERS command and command reply in client library
7954 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7955 When the command is given by user we register a pending command
7956 callback that will reprocess the command after the reply has been
7957 received from the server. When reprocessing the packet we then
7958 display the information. Thus, the USERS information is displayed
7959 now in the command callback instead of in the command reply
7960 callback. The processing of the command is same as previously
7961 when server has sent the command reply in the JOINing process.
7963 * Added to USERS command in silcd/command_reply.c to join the client,
7964 we didn't use to know about, to the channel after we've created
7965 a client entry for it. Also, for clienet we did know already still
7966 check whether it is on the channel or not and add it if not.
7968 * Removed silc_server_command_join_notify as the function and its
7971 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Changed the client's pending command handling to the same as the
7974 server's pending command handling. It is also now possible to
7975 execute command reply functions from other command reply
7976 function as the function callbacks for commands and command
7977 replies are one and same. The pending commands are not static
7978 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7979 in client connection context. Thus, pending commands are server
7980 connection specific as it is convenient.
7982 Changed the function silc_client_command_pending and
7983 silc_client_command_pending_del and added new function
7984 silc_client_command_pending_check. Removed the
7985 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7988 * Added cmd_ident, current command identifier, to the client
7989 connection context in lib/silcclient/client.h to keep track on
7990 command identifiers used in command sending. Client's command reply
7991 function handling now supports the mandatory command identifiers.
7993 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7994 funtions in client to fully support pending command callbacks.
7996 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7997 as one of the arguments to the application in the command reply
8000 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8001 before first releasing SILC but came back. Now it is removed again
8002 and should come back nomore. The FORWARDED flag was used only
8003 by the JOINing procedure by forwarding the command packet to router.
8004 Now, the JOINing procedure has been changed to more generic (due
8005 to various router environment issues) and FORWARDED is not needed
8006 anymore for anything. The protocol specification is yet to be
8009 Now, removed silc_server_packet_forward from server and the flag
8010 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8012 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8014 * Renamed NAMES command to USERS command. The NAMES was named that
8015 due to historical reasons. Now it is renamed. Also, rewrote
8016 parts of the USERS command. The nickname list is not sent anymore
8017 by the server. Only Client ID and mode lists are sent in the USERS
8018 command. Changed this also to the protocol specification.
8020 The client now resolves the names and stuff after it receives
8021 the USERS list from the server when joining to the channel.
8023 * WHOIS and IDENTIFY commands has been changed to support multiple
8024 Client ID's per command. One can now search for multiple users
8025 in the network by sending only one WHOIS or IDENTIFY command.
8026 Changed the code and the protocol specifications.
8028 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8029 uses silc_server_command_whois_parse to parse the request. */
8031 * If normal server, do not parse the WHOIS and IDENTIFY requests
8032 before sending it to the router. Saves some time.
8034 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8036 * Fixed JOIN command on client library. Wrong number of arguments
8037 used to crash the client.
8039 * Added silc_server_channel_has_global function to check whether
8040 channel has global users or not.
8042 * Added silc_server_channel_has_local function to check whether channel
8043 has locally connected clients on the channel.
8045 * The silc_server_remove_from_one_channel now checks whether the
8046 channel has global users or not after given client was removed from
8047 the channel. It also checks whether the channel has local clients
8048 on the channel anymore. If it does not have then the channel entry
8049 is removed as it is not needed anymore.
8051 * The silc_server_notify now checks on JOIN notify whether the joining
8052 client is one of locally connected or global. If it is global then
8053 the channel has now global users on the channel and that is marked
8054 to the channel entry. Also, it now saves the global client to
8055 global list who is joining and JOINs it to the channel. This is
8056 for normal server, that is.
8058 Changed silc_server_send_notify_on_channel,
8059 silc_server_packet_relay_to_channel and
8060 silc_server_packet_send_to_channel check if we are normal server
8061 and client has router set (ie. global client) do not send the
8062 message to that client, as it is already routed to our router.
8064 * Implemented LEAVE notify type handling in silc_server_notify
8067 * Tested LEAVE command in router environment successfully. Tested
8068 with two routers, two servers and two clients.
8072 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8074 * Implemented SIGNOFF notify type handling in silc_server_notify
8077 * silc_server_remove_id now removes the client entry from all channels
8078 it has joined and thusly sends SIGNOFF notify type.
8080 * Rewrote the NAMES list generation in server by removing two excess
8081 loops. The lists are created now inside one loop.
8083 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8085 * silc_server_remove_channel_user checks now also global list
8086 for channel and client.
8088 * silc_server_new_channel_user checks now both local and global
8089 list for channel and client. Fixed a bug in client id decoding.
8090 Used to decode wrong buffer.
8092 * silc_server_channel_message checks now both local and global
8093 list for channel entry.
8095 * Tested channel joining (hence JOIN) in router environment
8096 successfully. Tested with two routers, two servers and two
8099 * Tested channel message sending in router environment successfully.
8101 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8103 * Added silc_server_save_channel_key into server.[ch] to save the
8104 received channel key in Channel Key payload processing. It is
8105 also used in JOIN command reply handling.
8107 Equivalent function silc_client_save_channel_key added into
8108 client.[ch] into client library.
8110 * Changed JOIN command reply to send information whether the channel
8111 was created or not (is existing already) and the channel key
8112 payload. Changed protocol specs accordingly.
8114 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8115 the request was sent by ID and not by nickname. Crashed on
8118 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8120 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8121 now correctly save the received data.
8123 * silc_server_free_sock_user_data now notifies routers in the
8124 network about entities leaving the network.
8126 At the same time implemented functions silc_server_remove_id
8127 and silc_server_send_remove_id to receive and send REMOVE_ID
8128 packets. The packet is used to notify routers in the network
8129 about leaving entities. The ID removed will become invalid in
8132 * Added function silc_idlist_del_server into server. Removes and
8133 free's server entry from ID list.
8135 * silc_server_private_message function now checks, if we are router,
8136 that the destination ID really is valid ID, naturally.
8138 * In router when NEW_ID packet is received (for new client) the
8139 hash of the Client ID is saved in the ID Cache but the
8140 client->nickname is set to NULL, instead of putting the hash
8143 IDENTIFY command now also checks that client->nickname must be
8144 valid. If it is not if will request the data from the server who
8145 owns the client. Added new function
8146 silc_server_command_identify_check.
8148 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8149 to set the command to already allocated Command Payload.
8151 * Tested private message sending in router environment with two
8152 routers, two servers and two clients. Fixed minor bugs and now
8155 * Fixed segfault from client's NAMES command. Used to crash if
8158 * Forwarded packets must not be routed even if it is not destined
8159 to the receiver. Changed server code comply with this.
8161 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8163 * Added `require_reverse_mapping' boolean value to ServerParams
8164 structure. If TRUE (not default) the server will require that
8165 the connecting host has fully qualified domain name.
8167 If the reverse mapping is not required and hostname could not be
8168 found the IP address is used as hostname.
8170 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Implemented version string checking to both client and server.
8173 The check is incomplete currently due to the abnormal version
8174 strings used in development version of SILC.
8176 * Changed all command functions in server to use the new
8179 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8181 * Changed char *data to unsigned char *data in ID Cache system to
8182 support binary data as ID Cache data. Changed code to support
8183 binary data in lib/silccore/idcache.c.
8185 * Renamed silc_server_packet_relay_command_reply to
8186 silc_server_command_reply as it is normal packet receiving
8187 function. Rewrote the function to accept command replys for
8188 servers and not only for clients.
8190 * Mark remote router always as registered server if we are connecting
8191 to it. Otherwise, commands sent by the router to us are ignored.
8193 * All ID List find routines now returns the ID Cache Entry pointer
8194 as well if requested.
8196 * WHOIS command works now in router environment, tested with two
8197 routers, two servers and two clients.
8199 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8200 in router environment (as it is almost equivalent to WHOIS) but
8201 hasn't been tested thoroughly. Added new functions:
8203 silc_server_command_identify_parse
8204 silc_server_command_identify_send_reply
8205 silc_server_command_identify_from_client
8206 silc_server_command_identify_from_server
8208 * Disabled route cache adding because adding two different ID's with
8209 same IP replaces the old cache entry thus giving wrong route.
8210 The entry->router->connection is always the fastest route anyway
8211 so route cache may not be needed. Of course, new routes maybe
8212 established after receiving the ID when the entry->router->connection
8213 might not be anymore the most optimal.
8215 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8217 * Add route cache for received ID for fast routing.
8219 * Added silc_server_packet_route to route received packet on router
8220 that is not destined to us.
8222 * Renamed silc_server_get_route to silc_server_route_get.
8224 * Added id_string and id_string_len fields into SilcServer to
8225 include encoded ServerID for fast comparing without excess
8226 encoding of the ID's.
8228 * Cleaned up WHOIS command on server side. Added following static
8231 silc_server_command_whois_parse
8232 silc_server_command_whois_check
8233 silc_server_command_whois_send_reply
8234 silc_server_command_whois_from_client
8235 silc_server_command_whois_from_server
8237 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8238 arguments in command replies. All command functions should be
8239 updated to use this macro.
8241 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8243 * Minor typo fixes on command reply handling on server.
8245 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8247 * Added silc_server_command_add_to_channel internal routine to add
8248 the client to the channel after router has created the channel and
8249 sent command reply to the server.
8251 * Added generic silc_server_send_command to send any command from
8254 * Use static buffer with ID rendering instead of duplicating data.
8256 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8258 * Fixed a channel user mode bug when joining to a channel server gave
8259 everybody channel founder rights, oops.
8261 * We mark ourselves as the router of the incoming server connection
8262 if we are router ourselves. This way we can check in some packet
8263 sending functions whether it is locally connected server. For
8264 incoming router connections we put NULL.
8266 * For router sending packets locally means now always sending the
8267 packet cell wide; to local clients and local servers. For normal
8268 server sending packet locally means sending it to only local
8271 * Fixed the JOIN command to really work in router environment. If the
8272 channel is created it is always created by the router. Router is
8273 also responsible of making the initial joining to the channel,
8274 sending JOIN notify to the sending server and distributing
8275 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8276 does not exist server doesn't do anything else but forward the
8277 command to the router which performs everything.
8279 * Added silc_server_send_channel_key function to send the Channel Key
8282 * Added silc_server_create_channel_key to create new channel key. The
8283 channel key is now re-generated everytime someone joins or leaves
8284 a channel, as protocol dictates. Note: channel->key_len is the
8287 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8289 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8290 packet_receive.[ch] to separate packet sending and receiving
8291 routines. The server.[ch] now includes everything else including
8292 actual packet processing (writing and reading data) and other
8295 Renamed silc_server_private_message_send_internal to
8296 silc_server_send_private_message. The routine is still though
8297 used only to relay private messages as server does not send
8298 private messages itself.
8300 Renamed silc_server_new_channel to silc_server_create_new_channel
8301 and added new function sicl_server_new_channel that handles the
8302 incoming New Channel packet. Added also new sending function
8303 silc_server_send_new_channel to send New Channel Payload.
8305 * Added new function silc_server_notify to process incoming notify
8306 packet to the server/router. Server may then relay the notify
8307 to clients if needed.
8309 * Added new function silc_server_new_channel_user to process incoming
8310 New Channel User packet. Router will redistribute the packet and
8311 send JOIN notify to its local clients and locally connected servers
8312 if needed. Normal server will send JOIN notify to its local client
8313 on same channel when received this packet. Added also corresponding
8314 sending function silc_server_send_new_channel_user to sent the
8317 * Added boolean route argument to send_notif_to_channel and
8318 packet_send_to_channel functions to attempt to route the packet
8319 if it is TRUE and send only locally if it is FALSE.
8321 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8323 * silc_server_replace_id now broadcasts the received replace ID
8324 packet if it is not broadcast packet already. The router must
8325 broadcast to inform other routers about changed ID.
8327 * Added backpointer to server's router into SilcServer context in
8328 silcd/server_internal.h.
8330 * Fixed silc_server_packet_broadcast to send correct broadcast
8333 * The channel key is now distributed to the local client as soon
8334 as it is received from the router (in router environment) so that
8335 no other packet may be sent for the channel until client has
8338 * silc_server_remove_channel_user now broadcasts the received
8339 Remove Channel User packet if it is not broadcast packet already.
8340 The router must broadcast to inform other routers about removed
8343 * Added users field into SilcPacketContext that is a reference count
8344 of the context. One can increase the reference count by calling
8345 silc_packet_context_dup which is now changed to just increase the
8346 reference count instead of duplicating the data. The reference
8347 count is decresed by calling silc_packet_context_free that will
8348 free the data after the reference count hits zero.
8350 For now on the packet context and everything allocated into it
8351 (including the raw packet from network) must be freed by calling
8352 the new silc_packet_context_free function. Added also new function
8353 silc_packet_context_alloc that must be used now to allocate the
8354 context. This also means that if a routine is asynchronous from
8355 silc_[client/server]_packet_parse_type the packet context must
8356 be duplicated by calling silc_packet_context_dup. Otherwise it
8357 gets free'd after silc_[client/server]_packet_parse_type returns.
8358 Also, one must remember that if packet is duplicated then its
8359 reference count must be decresed by calling the free function as
8360 many times as it was duplicated.
8362 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8363 from both client and server.
8365 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8367 * Made joining to a channel working in router environment.
8369 * Cleaned up JOIN command on server side and create function
8370 silc_server_command_join_channel internal routine to make the
8373 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8375 * Changed silc_command_pending list to SilcDList. Also, added
8376 `ident' field to SilcServerCommandPending structure to identify
8377 the reply and to call correct callback.
8379 Added silc_server_command_pending_check function to replace the
8380 corresnponding macro. The silc_command_pending list is not
8383 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8384 to set identifier to previously allocated Command Payload. It
8385 is used to set identifier for command when resending Command
8388 * Added silc_command_payload_encode_payload to encode Command
8389 Payload buffer from SilcCommandPayload structure.
8391 * Added silc_argument_payload_encode_payload to encode Argument
8392 payload buffer from SilcArgumentPayload structure.
8394 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8396 * Changed WHOIS command to support router connection on server side.
8397 The whois request is always sent to router unless the server is
8398 standalone server. After server has received the reply from the
8399 router will it send the reply to the client.
8401 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8402 broadcast received broadcast packet. The function is used only
8403 by router. The broadcast packet is always sent to the router's
8406 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8407 render given ID to printable string, for log files for example.
8409 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8411 * Made basic router to router connections working. At least they
8412 can now connect to each other but nothing really works the way
8413 they are supposed - yet.
8415 * Added new initiator token to RouterConnection configuration
8416 file in silcd/serverconfig.[ch]. It is used to tell whether we
8417 are the initiator to the remote router or whether we'll expect
8418 the other end to connect.
8420 * Moved registering of listener task to silc_server_init, hence
8421 the server starts listenning as soon as it is run, even if it
8422 does not have connections to other routers. Let's see how well
8425 * Changed default connection retry timeouts for more suitable in
8428 * Removed cipher and such arguments from silc_idlist_add_client
8429 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8430 Added new function silc_idlist_add_data to add the keys and stuff
8433 * Added SilcIDListData structure and added it to SilcClientEntry
8434 and SilcServerEntry as their first field in the structure. This
8435 way we can explicitly cast the ID entries to the SilcIDListData
8436 structure and get common data for the entries. In past, we had
8437 to first check what type of connection it is and then cast it to
8438 correct ID entry type. Now, we can directly cast the opaque
8439 pointer to the SilcIDListData (no matter what ID entry it actually
8440 is) and get the data needed.
8442 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8444 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8445 in some circumstances even if threre were timeout tasks, though not
8446 IO tasks, but tasks anyway. Now fixed.
8448 * Defined SilcServerConnection structure to hold connection specific
8449 stuff about directly connected servers and routers. The definition
8450 is currently in silcd/server_internal.h. I thought about having
8451 a bit more important role fro this struct but for now it is used
8452 only when connecting to other server (or router actually).
8454 * Added connecting retry support in server when connecting to
8455 router(s). The retry feature implement exponential backoff
8456 algorithm. Also, added SilcServerParams structure to hold default
8457 parameters for server. For now, it include these retry settings
8458 and are hard coded. After server is moded to be as Silc Server
8459 Library this structure will be more important.
8461 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8463 * Changed client librarys channel->clients table to SilcList and
8464 changed code accordingly.
8466 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8468 * Changed client's channel table to SilcList and changed code
8469 accordingly. Also changed SilcChannelClientEntry to include back-
8470 pointer to the channel so that client entry can use that structure
8471 as list as well and we have fast cross-reference to the channel.
8472 This change dramatically decreased the complexity of channel
8473 handling with client entry and vice versa (removed one extra
8474 loop when searching for channel entry from many functions).
8476 * Changed server->sim from table to SilcDList and changed code
8479 * NAMES command can now be used from user interface. It will show
8480 the user list on the channel, neatly.
8482 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8483 Code now saves realname of the user if it becomes available.
8485 * Renamed configure.in to configure.in.pre and made ./prepare
8486 script to automatically add correct version string to
8487 configure.in which it creates from configure.in.pre.
8489 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8491 * NAMES command reply now shows users mode with the nickname when
8494 * Moved silc_client_ch[u]mode[_char] functions from
8495 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8496 place sucks, they are utility functions and should be in some
8499 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8501 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8504 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8508 * Added TRQ (efficient deque and list library) into lib/trq. This is
8509 a very good list library that is currently used in the SILC. Defined
8510 SilcList API over the library because I didn't like the API very
8511 much. See lib/trq/silclist.h for the API and examples of how to
8512 use the API. Fixed various places in the code to use the new
8513 SilcList API. The SilcList is meant for lists that has a structure
8514 already defined as a list. It is not suitable to add just some
8515 context to the list (in TRQ, the context is the list actually).
8517 So, I defined SilcDList that can be used for the purpose where
8518 predefined list structure does not exit. This can be used as
8519 such list. Now some context just can be added to the SilcDList.
8520 Currently this list is not used in the SILC just yet, though there
8521 are a lot places where this can replace dynamically allocated
8522 tables and I will fix these places, later, to use SilcDList.
8523 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8524 and use TRQ internally).
8526 Also fixed some annoying warning messages that the original TRQ
8527 code generated. Also minor changes to TRQ's Makefile.in.
8529 * Added support for querying by Client ID to both WHOIS and
8530 IDENTIFY commands into server, as required by the protocol.
8532 * Removed method function pointers from SilcBuffer structure. They
8533 weren't used to anything and just increased the context size for
8534 no good reason. This change also made silc_buffer_alloc and
8535 silc_buffer_free functions inline functions.
8537 * Disabled command flooding detection support until it's fixed so
8538 that it accepts commands in but does not execute them more than once
8541 * Added silc_net_localhost(), to return local hostname, into
8542 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8543 that must be initialized before calling silc_client_init.
8545 * Added new function: silc_server_send_notify_on_channels to send
8546 notify messages to all channels client has joined. It is assured
8547 that the message is sent only once per client.
8549 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8550 lib/silcutil/silcutil.[ch] as silc_format function. The new
8551 function is generic and is used by server as well, not only by
8552 the logging routines.
8554 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8555 the provided version string was not acceptable. Added new function:
8556 silc_ske_check_version into lib/silcske/silcske.h. The function
8557 must be implemented by the application (client or server) and it
8558 does not reside in the SKE library. The function checks the version
8559 string remote end sent.
8561 * Added back pointers (to opaque context and to SilcSocketConnection)
8562 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8564 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8565 duplicate packet context structure.
8567 * Changed `notify' client operation to send same arguments as client
8568 receives from server except for ID's. ID's are mapped to correct
8569 ID entry and that is returned. Also, if channel entry is not sent
8570 by server but the notify is for channel the channel entry is sent
8571 to application (otherwise application doesn't know that it is for
8572 channel (library gets it from packet's Destination ID)).
8574 * Added silc_client_remove_from_channels into client library to
8575 remove a client from all channels it has joined to. Used when
8576 received SIGNOFF notify from server. Added also new function
8577 silc_client_replace_from_channels to replace old ID entry with
8578 new ID entry on all channels. Used when received NICK_CHANGE
8581 * Fixed ID Cache list handling in silc_idlist_get_client in
8582 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8583 to get (or query) client by ID.
8585 * Updated TODO list.
8587 * Added connection authentication status message defined by the
8588 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8589 support for these into the code in client and server side.
8591 * Added generic function silc_client_send_command to send any command
8592 with variable argument list. Application should use this function
8593 to send commands if the command functions provided by the library
8594 does not suite for the application's user interface needs.
8596 * Added new `failure' client operation. Application is notified about
8597 received failure packet if client is executing a protocol. In this
8598 case the protocol's execution has failed.
8600 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8601 is required by the protocol.
8603 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8604 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8607 * Added status flag to SilcSKE object to indicate realtime status
8608 of the SKE protocol.
8610 * Application receives now exactly same command reply arguments as
8611 the library receives from server. However, if ID is received the
8612 corresponding ID entry is returned to the application (eg. Client
8613 ID is mapped to correct SilcClientEntry entry and that is returned).
8614 Changed command_reply client operation due to this change.
8616 * Changed all ID's in commands and in command replys as ID Payloads.
8617 Change affected both client and server side codes.
8619 All ID's sent in SILC network (with execption of ID's in SILC
8620 Packet header) are sent in ID Payload to support variable length
8623 * Server now notifies nick changes and notifies all clients on
8624 the channels about the new nickname (about the new Client ID,
8627 * Implemented CMODE command to change channel modes. Supports all
8628 channel modes defined by the protocol specs except ban and invite
8629 lists. (Also, private channel key mode is supported but support for
8630 setting private channel key in client is missing, thus, this mode
8631 has no effect on client side (except that server requires that the
8632 client uses private channel key and normal channel traffic does not
8635 Also, invite mode works per se, but INVITE command does not work
8636 yet correctly, so you can set channel as invite only channel but
8637 inviting clients to the channel does not work (it is yet to be
8638 thought what's the best way to do it).
8640 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8641 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8642 Implemented CUMODE command to change user's mode on the channel.
8643 Supports all modes defined by the protocol specs.
8645 * Added NAMES command reply to return users modes on the channel.
8647 * Removed unnecessary and slow ciphers from lib/silccrypt.
8649 * Set SO_KEEPALIVE option to connection sockets by default.
8651 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8653 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8654 redefined the Notify Payload into protocol specs.
8656 * Added silc_id_payload_parse_id to get ID directly from raw
8659 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8661 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8662 accept searching by Client ID as well.
8664 * Added support for LEAVE and SIGNOFF notify types in client library.
8666 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8667 to parse ID Payload from raw data.
8669 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8671 * Added flags parameter into silc_ske_assemble_security_properties
8672 function in lib/silcske/silcske.[ch].
8674 * Changed notify client operation to fit better for notify messages
8675 sent by server. The notify payload received from server is now
8676 passed to the application (after parsing it to SilcNotifyPayload).
8677 It is application's responsibility to retrieve the arguments
8678 from the payload and show the message the way it wants. The message
8679 sent by server is implementation specific.
8681 * Changed public keys to comply with the protocol specification.
8682 Old public keys are not supported anymore and are not compatible.
8684 * Removed nickname from Channel Payload as the latest draft removed
8685 it. The client must resolve the nickname from the NAMES command
8686 reply received when it joined the channel.
8688 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8690 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8692 * Fixed some errors in protocol specification drafts.
8694 * Created lib/silccore/silcnotify.c to implement Notify Payload
8695 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8696 generic payloads described by protocol specifications. The file
8697 includes implementations for ID Payload and Argument Payload.
8699 * Changed Command Payload implementation to use the new Argument
8700 Payload. Changed command_xxxx_payload to command_payload_xxxx
8701 to comply with SILC coding conventions.
8703 * Added suppport for Argument Payload handling in Notify Payload
8704 implementation as protocol requires it. Added the new support
8705 into server and client lib as well.
8707 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8709 * Added support for multiple nicknames on same channel. [n] is
8710 added locally to the nickname if there are more than one same
8711 nicknames on the channel.
8713 * Server now sends all nicknames that matched WHOIS request.
8714 Client also shows the list received from server.
8716 * Added TOPIC command to client side. User can now set and show
8717 current topic on channel.
8719 * Added MOTD command to client and server. Also, server sends the
8720 motd when client connects to the server.
8722 * Changed version strings to comply ISO 8601.
8724 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8726 * Fixed protocol error handling in client library. It should now
8727 cope even if the SKE fails for some reason.
8729 * Made new protocol specification drafts for submitting to IETF.
8731 * Implemented TOPIC command to server in silcd/command.c.
8733 * Added two new notify types into lib/silccore/silcnotify.h:
8734 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8735 notify nickname change and topic setting/change on a channel.
8737 * API change of command_reply operation in client library. The
8738 application gets now the status type received from server as well.
8740 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8742 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8744 * Cras fixed and optimized the packet handling even further and
8745 it should work now. Minor change to the prototype of function
8746 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8748 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8750 * Added new function into lib/silcutil/silcschedule.[ch]:
8751 silc_schedule_with_fd to select() a specified fd. The function
8752 returns after timeout expires or data arrives or goes. The
8753 function is used by packet routines to wait that all data is
8754 received from network.
8756 * Fixed data reading from network in lib/silccore/silcpacket.c.
8757 The code now assures that all data is read from the fd and then
8758 continues packet processing. This was a bug fix since the code
8759 used to drop some data in some circumstances.
8761 * Added new function into lib/silcclient/client.[ch]:
8762 silc_client_start_key_exchange to start key exchange after
8763 connection has been established to server. The code internally
8764 now uses this funtion but its main purpose was to provide it
8765 for applications that perform their own connecting. After
8766 application has created a connection it merely calls this
8767 function to start the key exchange between client and server.
8768 The library takes care of everything else after that.
8770 Updated also lib/silcclient/README to explain the usage of
8773 * Do not send to application information that connection has
8774 been established. Application gets notified it by connect
8777 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8779 * Applied cras's patch to add silc_schedule_one function. The
8780 function runs scheduler once and returns.
8782 * Fixed the scheduler after cras messed it up. The timeout
8783 handling works now as it's supposed to work.
8785 * Added into lib/silccore/ silcnotify.h to include notify
8786 message types support. Changed silc_server_send_notify*
8787 functions, in server.[ch], to support those new notify types.
8788 Added the support for the notify types into client library,
8789 as well. Added new notify client operation into ops.h in
8792 * Changed silc_server_packet_send_to_channel to send normal
8793 packets instead of just channel message packets. The function
8794 is now used to send the notify packets to channels. It is not
8795 used to send channel message packets anymore, as server never
8798 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8799 va_arg()s as it seems to require it nowadays. I guess, if SILC
8800 is compiled with older va_arg() the new code should work anyway.
8802 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8804 * Splitted core library. Core library (lib/silccore) includes
8805 now only SILC protocol specific core (and common) components.
8806 Created new utility library (lib/silcutil) that includes more
8807 generic purpose stuff. The stuff for util library was taken
8808 from the old core library. This was minor and easy split.
8810 * Created SILC Client Library (lib/silcclient) that includes
8811 implementation of the SILC client without user interface. This
8812 was major move from silc/ directory. The code has been changed
8813 so that it is transparent towards the user interface. The
8814 silc/ directory includes now the same user interface as before
8815 and it uses the new client library. Read lib/silcclient/README.
8816 Basicly, the client library performs everything else related
8817 to SILC except user interface handling. Also, configuration
8818 files are considered to be part of user interface and library
8819 does not handle them.
8821 This change also changed a lot of structures, function naming etc.
8822 Most important change was that SilcClientWindow object was
8823 renamed to SilcClientConnection in the client library. Created
8824 also new file lib/silcclient/ops.h. Also added new files
8825 silc/local_command.[ch] and silc/client_ops.[ch].
8827 All these changes were made to make it easier for user interface
8828 designers to create what ever user interface for the SILC client
8831 It is also expected that the server will be moved to lib
8832 directory as well and SILC Server Library will be created;
8833 sometimes in the future.
8835 * Removed Local commands from lib/silccore/silccommand.h as
8836 they are application specific and new client library does not
8837 handle any of those anymore.
8839 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8840 old client implementation in silc/.
8842 * Added support for callback functions in SILC_LOG_* macros.
8843 Application can now set its own callbacks that will be called
8844 instead of using the default functions that will always print
8845 the debug messages to stderr (or stdout). Also, debugging can
8846 now be disabled by setting silc_debug to FALSE and re-enabled by
8847 setting it to TRUE. Note, that logging will still work even
8848 if debugging is disabled.
8850 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8851 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8852 silc_log_reset_debug_callbacks.
8854 * To enable debugging in silc client one must give now -d
8855 option on command line.
8857 * Changed silc_schedule_init to automatically allocate task queues
8858 if they are not allocated before calling it.
8860 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8862 * Added GMP 3.1 into math library.
8864 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8866 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8867 a channel in SILC network. The packet is used by servers and
8868 routers to notify other routers that user has left a channel.
8869 This little feature was missing until now. Added the feature
8870 to protocol specification as well.
8872 Added functions: silc_server_send_remove_channel_user and
8873 silc_server_remove_channel_user into server.[ch].
8875 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8876 lib/silccore/silcpacket.h. However, they are not implemented
8879 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8881 * Fixed joining to a channel and sending channel messages
8882 between server and router. The channel message sending should
8883 now work inside a cell.
8885 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8887 * Fixed the private message sending between server and router.
8888 The private message sending should now work inside a cell.
8890 * Added silc_server_replace_id into server.[ch] to replace
8891 existing ID in the SILC network.
8893 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8894 and silc_idlist_replace_server_id into idlist.[ch] in server.
8896 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8898 * Fixed the server to server connections. Server can again now
8899 connect to router. Router to router connections probably does
8902 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8904 * Added dynamic protocol registering support. Now protocols can
8905 registered and unregistered on the fly. Patch by cras.
8907 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8909 * Added lib/contrib directory to hold routines that some platforms
8910 don't have but are needed by SILC.
8912 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8913 into lin/contrib to provide getopt() and getopt_long() for
8914 those who don't have it.
8916 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8918 * Added AWAY command to client. When away message is set and
8919 client receives a private message packet the client automatically
8920 replies to the sender with the away message.
8922 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8923 bug seemed to be the cause of recent problems when compiling
8926 * Added version detection support to SKE protocol specification
8927 and added the new changes to the SKE implementation as well.
8928 There were other minor changes in the SKE protocol as well.
8930 Many changes in lib/silcske/silcske.[ch] and in
8931 lib/silcske/payload.[ch].
8933 * Added ^U functionality, clear input line. Patch from cras.
8935 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8937 * Mainly small bugfixes on core library. Fixed some debugging
8938 logging and buffer overflow in silclog.c.
8940 * Updated config.sub and config.guess on the distribution tree.
8942 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8944 * Added command lagging support in server. Client may execute
8945 commands now only once in two seconds.
8947 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8949 * Optimized packet reception. MAC computation and checking is now
8950 also more optimized. A lot previously duplicated code is now
8951 used as generic by both client and server.
8953 * Fixed key pair generation in clientutil.c
8955 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8957 * Added into lib/silccore/silcbufutil.[ch] new function;
8958 silc_buffer_realloc.
8960 * Moved generic packet sending/encryption functions to
8961 lib/silccore/silcpacket.[ch] from client and server. Some
8962 rewriting of the functions.
8964 * Moved all generic packet reception/decryption functions to
8965 lib/silccore/silcpacket.[ch] from client and server. The
8966 packet processing is now much cleaner in both client and server.
8967 These were major changes in both client and server.
8969 * Created many common functions in server to do packet sending.
8970 Previously code were duplicated a lot, this has been removed
8973 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8975 * Rewrote major parts of the ID cache system. Don't know
8976 whether it is better now or not but at least the API is more
8979 * Major rewrite on ID cache stuff on client because of the ID
8980 cache API changes. Added idlist.c to client.
8982 * Also major rewrite on ID cache stuff on server as well.
8983 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8984 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8985 in hand, instead they are all put into the ID cache system now.
8986 All server_idlist_* routines uses ID cache now instead of
8987 traversing its own lists (those lists does not exist anymore).
8988 SilcIDList though still exists. Also, SilcXXXEntry's are
8991 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8993 * Finally made the SKE implementation compliant to the protocol
8994 specification. All mp integers are now binary encoded as
8995 opposed being HEX encoded.
8997 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9000 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9001 functions: silc_[encode/decode]_pem. Also added function
9002 silc_encode_pem_file to PEM encode with newlines ('\n') for
9005 * SILC public keys are now encoded either PEM or binary. Same
9006 option is for private keys as well. By default private keys
9007 are binary encoded and public keys PEM encoded. Silly HEX
9008 encoding were removed.
9010 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9011 function to create fingerprints.
9013 * Fixed a bug in SHA1; does not change the original data anymore.
9015 * Partly implemented INFO command on client and server side.
9016 Fixed CLEAR command. Changes to SERVER command; show current
9017 server(s) when giving command without arguments. Added
9018 VERSION command to client.
9020 * Added check to server that unregistered connections cannot
9021 execute commands (unless it is specificly allowed).
9023 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9025 * Fixed screen refresh.
9027 * Fixed channel joining bug from client. On some circumstances
9028 client tried to join to a channel it had already joined.
9030 * Added public key verification process into client's protocol.c.
9031 The client now verifies the public key from user and saves
9032 it into ~./silc/serverkeys/ directory.
9034 Added into: clientutil.[ch]: silc_client_verify_server_key.
9036 * Changed SKE protocol's silc_ske_initiator_finish function
9037 to accept callback function that verifies the received public
9038 key. Removed old silc_ske_verify_public_key function.
9040 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9042 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9043 silc_pkcs_private_key[_data]_set.
9045 * Made the password and public authentication more cleaner in
9046 server's protocol.c.
9048 * Removed historic and obsolete protocol `channel_auth' from
9049 both client and server.
9051 * Removed wrong way of sending command status messages from
9052 server to client in server's command.c. The old way violated
9053 protocol specification.
9055 Changes to silccore/silccommand.[ch]: removed
9056 silc_command_encode_status_payload -> not needed anymore,
9057 changed silc_command_encode_payload_va to accept extra
9058 argument on variable argument list. The argument type must
9059 now be provided to the function. Also, added new function:
9060 silc_command_encode_reply_payload_va which is same as
9061 normal command_encode_payload_va except command status type
9062 is provided as extra argument.
9064 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9066 * Added ~./silc directory handling. The directory includes the
9067 public and private keys for the client.
9069 Added silc_client_check_silc_dir, silc_client_create_identifier
9070 and silc_client_load_keys.
9072 * Implemented SILC protocol compliant public key. Added public
9073 and private key saving to and loading from files.
9075 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9076 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9077 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9078 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9079 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.

9086 * Added silc_server_get_route (route.[ch]) to get connection
9087 data for the fastest route for given ID.

9090 were re-defined in the SILC Protocol Specification and the
9091 implementation now complies with the specification.
9093 * Implemented PING command on client and server.

9109 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
