1 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
3 * Added global variable silc_log_timestamp that tells silclog
4 wether to print or not the timestamp in the logging files.
5 Affected file lib/silcutil/silclog.[ch].
7 * Added silcd configuration option Timestamp in the Logging
8 section. Affected file silcd/serverconfig.[ch],
9 doc/example_silcd.conf.in.
11 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
13 * Fixed fingerprint checking to check for entirely empty
14 fingerprint instead of two first bytes when determining
15 if it is set. Bug #18. Affected file silcd/command.c.
17 * Fixed duplicate PKCS name registering to not allow it.
18 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
20 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
22 * Conditionalize non-gcc compiler optimizations for various
23 platforms, enable those commented out. Cleanups.
24 Affected file lib/silcmath/mpi/configure.in
26 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
28 * silc_rng_exec_command() left zombie processes if command
29 didn't generate any output. Affected file
30 lib/silccrypt/silcrng.c
32 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
34 * Rewrote iconv checking, introduce --with-iconv for systems
35 which rely on libiconv. Check if iconv() provided by libc
36 is good enough, otherwise demand libiconv. Affected file
39 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
41 * Search for ldopen() also in libc. This enables SIM support
42 on *BSD systems. Based on patch from Alex Zepeda. Affected
45 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
47 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
48 This fixes prepare on *BSD systems. Affected file
51 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
53 * More fixed for not having purge timeout for global clients
54 that are on channel. Affected files silcd/command_reply.c
57 * Fixed the rekey protocol to work with backup router connections.
58 Rekey packets are now allowed on disabled connections as
59 well. Affected files silcd/packet_send.c and server.c.
61 * Do not switch to be as backup router when shutting down and
62 closing the primary connection. Affected file silcd/server.c.
64 * Fixed memory leaks in backup router deleting. Added
65 silc_server_backup_free to free all data during shutdown of
66 server. Affected files silcd/server_backup.[ch].
68 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
70 * Do not process commands if the sock->user_data is NULL.
71 Affected file silcd/command.c.
73 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
75 * Fixed buffer overflow and security problems (loosing bits
76 in CFB encryption) in SILC RNG. Problems reported by
77 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
79 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Added yet more checks that client is not expired on global
82 list if it is on channels. Affected file is
83 silcd/command_reply.c.
85 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
87 * Merged c0ffee's MIME signal patch which adds support for
88 sending also MIME messages in Irssi SILC Client, and handling
89 received MIME messages in a signal (and perhaps doing something
90 to non-textual MIME messages).
92 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Fixed pending command deletion in server and client library
95 to check the whole list instead of breaking after first found.
96 The affected files are silcd/command.[ch] and
97 lib/silcclient/command.[ch].
99 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Return NO_SUCH_CHANNEL error in USERS for channel that is
102 secret or private, otherwise it's possible to find out
103 whether a secret channel exists or not. Affected file
106 * If CMODE change fails during the mode setting, assure that
107 the old mode mask is set for the channel back. Affected
108 file silcd/command.c.
110 * Fixed passphrase saving on +a channel on normal server
111 after successful JOIN command. Affected file silcd/command.c.
113 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
115 * Remove server/router operator privileges in DETACH command,
116 since it's possible to resume to server where these
117 privileges would not be allowed for the client. Affected
118 file silcd/command.c.
120 * Do not set to wait for backup in rehash of the server.
121 Affected file silcd/server.c.
123 * Do not check listener sockets when counting how many
124 socket connections we have. Affected file is
127 * Do not announce disconnected clients that are remaining
128 in history (for WHOWAS). This is because SIGNOFF notify
129 for these has been sent earlier already. Affected file
132 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
134 * Buffer overflow with CUMODE command's mode->mode character
135 conversion. Reported by Ville Räsänen. Affected file
136 lib/silcutil/silcutil.c.
138 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
140 * Allow heartbeat packets to go disabled connections anyway.
141 Affected files silcd/server.c and silcd/packet_send.c.
143 * Do not broadcast New Channel packets with List flag set
144 in the packet to backup routers. The router must check
145 for the correctness of the packets before sending them.
146 It is possible that router will have enforce Channel ID
147 change and this would cause desync in the backup router.
148 Affected file silcd/packet_receive.c.
150 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
151 are handled in list parsing. They are not list packets
152 anymore. Affected file silcd/packet_receive.c.
154 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Stop waiting for backup router through the timeout, not
157 directly after backup router has arrived. Affected file
160 * Do not re-create channel keys and send them when removing
161 clients in server shutdown. Affected files are
162 silcd/server_internal.h and silcd/server_util.c.
164 * Notify distribution to backup routers was missing from
165 the silc_server_send_notify_dest function which caused
166 desyncing problems with backup router. Affected file is
169 * The client's channel removing was working wrong on
170 backup router. It assumed that it doesn't know global
171 information but backup router does know. For this reason
172 it could remove channel when it wasn't supposed to do that.
173 Affected file silcd/server.c and silcd/server_util.c.
175 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
177 * Stop for a couple seconds after badkup router has become
178 primary router. Affected file silcd/server.c.
180 * Added silc_server_remove_servers_by_server, which is used
181 to remove servers originated from some other server. Also
182 clients of those servers can be removed too. Affected file
183 silcd/server_util.[ch].
185 * When removing clients after a server has signed of remove
186 also all servers behind that server (unless they are known
187 to be available locally), and send SERVER_SIGNOFF for each
188 of the server separately. Also the signed off clients are
189 sent now separately per signed off server. The affected files
190 are silcd/server.c and silcd/server_util.[ch].
192 * All servers added with silc_idlist_add_server must always
193 have both "router" and "connection" pointers set. Otherwise,
194 bad server entries may be left around in the cache.
195 Affected file silcd/command_reply.c.
197 * Do not create the channel key in NEW_CHANNEL packet
198 processing if the channel is empty. Affected file
199 silcd/packet_receive.c.
201 * Completed backup router support for standalone routers.
202 Supports also servers in the cell that do not use the backup
205 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Fixed a bug in silc_string_regexify which did not add '^'
208 at the start of each string, and thus the matching was
209 not explicit. For example ban list iikone@*!*@* would
210 match also "priikone", which is wrong, it would have to be
211 *iikone@*!*@* to match also "priikone". Affected
212 file lib/silcutil/unix/silcunixutil.c.
214 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
216 * Enable all local server connections before updating client
217 caches when we've become backup router. Otherwise, signoff
218 packets may not reach the clients. Affected files are
219 silcd/server.c and silcd/server_util.[ch].
221 * Fixed a bug in version string parsing which could crash
222 the program with specially formatted version string.
223 Bug reported and patch provided by Ville Räsänen. Affected
224 file lib/silcutil/silcutil.c.
226 * Handle the disconnection immediately when DISCONNECT
227 packet is received in server. Affected file silcd/server.c.
229 * Primary router now waits a short time (10 seconds) for
230 backup router connection before accepting any other
231 connection (except local). Affected file silcd/server.c,
234 * Fixed a crash in client libary in NICK_CHANGE notify when
235 NICK_CHANGE arrived for client entry we are resolving
236 currently. Affected file lib/silcclient/client_notify.c.
238 * Call the sconn->callback completion even if error had
239 occurred. Start reconnecting always if connection to
240 primary router fails during backup router protocol.
241 Affected files silcd/server.c and server_backup.c.
243 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Added functions silc_server_send_opers and
246 silc_server_send_opers_notify to send packets stricly
247 to operators. Added macro SILC_SERVER_SEND_OPERS macro
248 to send variable argument notify to operators.
249 Affected files silcd/packet_send.[ch] and silcd/server.h.
251 * Removed UMODE rights checking with UMODE_CHANGE notify.
252 Affected file silcd/packet_receive.c.
254 * Server/router operator now receives notify when network
255 switches to backup router and when it resumes the use of
256 primary router. Affected file silcd/server.c and
257 silcd/server_backup.c.
259 * Fixed the updating of client information after backup
260 resuming protocol is over; update all except local clients
261 to the new primary router. The affected file is
264 * Added support for closing active connections in rehash
265 that were unconfigured by the user. Supports currently
266 closing server and router connections. Affected file
269 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
271 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
273 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
274 is NULL since seems that on some platforms NULL is allowed
275 and on some it's not. Fallback encoding is used instead.
276 Affected file lib/silcutil/silcstrutil.c.
278 * Fixed statistics updating for incoming server connection
279 which could cause problems when re-connecting. Affected
282 * Preliminary backup router support for standalone router
283 added. Affected files in silcd/.
285 * Mark server connections in backup router disabled before
286 and after backup protocol. Affected file is
287 silcd/server_backup.c.
289 * Added support for reconnecting to remote server connection
290 even if the protocol fails, and if the configuration wants
291 us to keep trying to connect anyway.
293 Server connection is not allowed to backup router if
294 backup router does not have connection to primary router yet.
296 Affected file is silcd/server.c.
298 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
300 * Added silc_client_udpate_server function to update changed
301 server info. Affected file lib/silcclient/idlist.[ch].
303 * Added check for server entries that are being resolved when
304 notify is received. If being resolved, handle the received
305 notify only after it's resolved so that all notifys are
306 handled in same order as received from the server.
308 Added similar resolver check to channel entries. Every
309 notify that cause resolving of any information that affects
310 channel entry marks the channel entry in waiting state.
311 After whatever resolving is over the waiters are signalled
312 and only then the notifys are handled in the same order
313 as delivered from the server.
315 Affected files are lib/silcclient/idlist.[ch], and
318 * Fixed KILLED notify handling in normal server. Affected
319 file silcd/packet_receive.c.
321 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
322 is locally connected, or was locally connected (but may
323 be detached and connection is not active). Added also
324 SILC_IS_LOCAL for checking this status. Affected files
325 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
326 silcd/server.c and silcd/server_internal.h.
328 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Don't send or handle TOPIC_SET if topic is already set and
331 is same as being set. Affected files silcd/command.c and
332 silcd/packet_receive.c.
334 * Fixed CMODE change rights checking to work correctly when
335 removing modes by operator. Affected file is
338 * Fixed some handling with New Channel packet in router and
339 fixed some CMODE_CHANGE notify handling in server and router.
340 Affected file is silcd/packet_receive.c.
342 * Changed "disconnect" client operation to include the
343 reason of the disconnection and optional disconnection
344 message. Affected file lib/silcclient/silcclient.h.
346 * Made the compilation of lib/contrib/ stuff conditional.
347 Affected files configure.in.pre, lib/contrib/Makefile.am.
349 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
351 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
352 to the sender of the notify too, to avoid situation where two
353 notifys are in the network at the same time going to oppsite
354 directions. Affected file silcd/packet_receice.c.
356 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
358 * Delete the client from channel even if the cilent->id is
359 NULL. It was possible that client was deleted without
360 removing from channels (theoretically at least). Affected
361 file silcd/server.c and silcd/server_util.c.
363 * Free the client data too when resuming is not successful.
364 Affected file silcd/packet_receive.c.
366 * Merged some code from c0ffee's silc-plugin. Affected files
367 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
369 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
370 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
371 to the primary router connection, the other one returns
372 TRUE if packet must be broadcasted to network.
374 * All notifys that are destined to primary router (to network)
375 are now automatically sent to backup routers even if the
376 router is standalone (and has backup router). Affected files
379 * Added --without-irssi and --without-silcd configuration
380 options for disabling the compilation of these applications.
381 Affected file configure.in.pre and prepare.
383 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
385 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
386 UTF-8 encoding and decoding. Added also new encodings
387 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
389 Added also SILC_STRING_LANGUAGE which is language and charset
390 specific encoder and decoer for those platforms that support
391 iconv(). It can convert the UTF-8 to and from the locale
392 specific character set.
394 Affected file lib/silcutil/silcstrutil.[ch].
396 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
398 * Added function silc_get_command_name to the file
399 lib/silcutil/silcutil.[ch].
401 * Improved the server debug output a bit. Affected files are
404 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
406 * Save the channel passphrase when received succesful JOIN
407 command reply from router, on normal server. Otherwise
408 joinig +a channels from normal server is not possible.
409 Affected file silcd/command.c.
411 * Fixed a bug in TOPIC_SET notify handling. The notifier
412 may be other than client too, like server or channel.
413 It expected it to always be only client and ignored the
414 notify. Affected file silcd/packet_recieve.c.
416 * Removed some (unnecessary) debug printing from
417 lib/silccore/silcid.c and lib/silccore/silcargument.c.
419 * Do not force CMODE_CHANGE when server is announcing new
422 Router announces stuff only after server reannounces channel
423 after CHANNEL_CHANGE notify.
425 These fixes optimizes the announcing procedure, and perhaps
426 fixes some problems too. Affected file silcd/packet_receive.c.
428 * Fixed SERVER_SIGNOFF sending to local clients. It was
429 totally broken and sent the notify to all local clients,
430 instead of only to those that was on same channel as the
431 signing off clients. Affected file silcd/server_util.c.
433 * Added -D option to server. It can be used to give debug
434 level. The levels are from 0 - 99, and are predefined for
435 smooth server debugging. (see silcd.c for the predefined
436 levels). Affected file silcd/server.c.
438 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
440 * Fixed a bug in Irssi SILC client to close the connection
441 properly when disconnecting from server. Affected file
442 irssi/src/silc/core/client_ops.c.
444 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
446 * When authenticating as founder during JOIN command, check
447 that the one authenticating becomes the only founder on the
448 channel. Affected file silcd/command.c.
450 * Better checking for founder mode setting when CUMODE_CHANGE
451 notify is received. Affected file silcd/packet_receive.c.
453 * Close all connections when shutting down the server by sending
454 DISCONNECT packet. Close all listeners too when shutting
455 down the server. Affected file silcd/server.c.
457 * Handle DISCONNECT packet correctly in client library by
458 calling the "disconnect" client operation. Affected file
459 lib/silcclient/client.c.
461 * Handle local errors correctly during resuming. Affected
462 file lib/silcclient/client.c.
464 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
466 * The log file is not dupped internally anymore in
467 lib/silcutil/silclog.c. Fixed memory leaks too.
469 * The scheduler now dispatches all pending timeout tasks
470 when it is uninitialized with silc_schedule_uninit.
471 Affected file lib/silcutil/silcschedule.c.
473 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
475 * Added --enable-stack-trace option to configure. Added
476 memory allocation stack trace support. Added files
477 lib/silcutil/stacktrace.[ch]. Affected files are
478 lib/silcutil/silcmemory.[ch].
480 * Fixed memory leaks from libraries and server. Affected
481 files around the tree.
483 * Reverted back a fix made to CUMODE which broke it.
484 Affected file silcd/command.c.
486 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
488 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
489 core library, and implemented it. All textual messages SHOULD
490 use this flag and the message MUST be UTF-8 encoded.
491 All text messages sent by Irssi SILC client are now UTF-8
492 encoded (regardless whether the terminal supports UTF-8 or not).
493 Affected files are lib/silccore/silcchannel.h,
494 irssi/src/silc/core/silc-servers.c, silc-channels.c and
497 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
499 * Added lots of new statistics updating that was missing from
500 the server and router code. Affected files in silcd/.
502 * Sending SIGUSR1 signal to server now dumps the current
503 server statistics into /tmp directory. Affected file is
506 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
507 the SILC Hash Interface also. Added new functions
508 silc_hash_get_name, silc_hash_init, silc_hash_update and
509 silc_hash_final. Affected file lib/silccrypt/silchash.c.
511 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
513 * Added some better info printing for client during connecting.
514 Affected file silcd/server_util.c.
516 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
517 to silence a user on a channel. Affected files are
518 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
519 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
520 and silcd/packet_receive.c.
522 * Fixed a fatal bug in handling of malformed command payload.
523 Affected file silcd/command.c.
525 * Fixed a double free when announcing channel users to router.
526 Affected file silcd/server.c.
528 * After successful authentication to channel founder mode, check
529 that there isn't anyone else with founder mode on the channel.
530 The one that authenticated will become founder and anyone
531 else is demoted. Affected file silcd/command.c.
533 * Added error printing of any error that has occurred during
534 any command in client library. Affected file is
535 irssi/src/silc/core/client_ops.c.
537 * Removed some error printing from the client library and left
538 it for the application to worry (from the error status it
539 receives in 'command' client operation. Affected file is
540 lib/silcclient/command.c.
542 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
544 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
545 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
546 Starting key agreement with itself is denied. Affected file
547 is lib/silcclient/client_keyagr.c.
549 * Fixed some error checkings from the SFTP library which caused
550 misbehaviour. Affected files are lib/silcsftp/sftp_client.c
551 and lib/silcsftp/sftp_util.c.
553 * Added new "debug" and "debug_string" settings to Irssi SILC
554 client which can be used to print runtime debugging on the
555 Irssi's screen. Available when compiled with --enable-debug
556 option. Affected file irssi/src/silc/core/silc-core.c.
558 Tue Jun 11 16:36:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
560 * Fixed a missing variadic parameter in a function call that
561 caused server crash when a non-allowed connection arrived.
562 Reported by Richard Becker. Affected file silcd/server.c.
564 Mon Jun 10 16:29:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
566 * Added WATCH list sending to backup routers from router.
567 The WATCH command is sent by the router to the backup
568 router. Affected file silcd/command.c.
570 * Mark the backup_router flag for RouterConnection entry
571 if the backup router stuff is defined in the config file.
572 Affected file silcd/serverconfig.c.

1085 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1086 silcd/command_reply.[ch].
1088 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * The LIST command reply in client libary now adds new channel
1091 entry if the returned channel doesn't exist yet in cache,
1092 and returns the channel entry to the application in the
1093 command_reply client operation. Affected file is
1094 lib/silcclient/command_reply.c.
1096 * Changed the channel message payload's MAC generation to
1097 include the IV in the MAC as well. This way all relevant
1098 parts of the channel message payload are authenticated also
1099 with the channel message MAC (and not only by packet MAC).
1100 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1101 Affected file is lib/silccore/silcchannel.c.
1103 * Fixed the SKE to save the remote version, since the
1104 silc_ske_parse_version mistakenly checked wrong version,
1105 after it replaced the start payload. Affected files are
1106 lib/silcske/silcske.[ch].
1108 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1110 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1111 string utility functions. Added there also new functions
1112 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1113 Affected files lib/silcutil/silcstrutil.[ch].
1115 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1116 files are lib/silcutil/silcstrutil.[ch].
1118 * Defined that the security property fields in SKE SHOULD be
1119 UTF-8 encoded, defined that version string MUST be US-ASCII
1120 encoded, defined that passphrases sent in connection
1121 authentication protocol MUST be UTF-8 encoded. Implemented
1122 these to the client and server. Defined also that other
1123 passphrases sent in the protocol MUST be UTF-8 encoded.
1124 Affected files are lib/silcske/silcske.c,
1125 lib/silcclient/protocol.c, silcd/protocol.c,
1126 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1128 * Changed the silc_client_close_connection interface to not
1129 need the SilcSocketConnection which should not be visible
1130 to application. Affected files are lib/silcclient/client.c
1131 and lib/silcclient/silcclient.h.
1133 * Rewrote the text for Private Message Key Payload in the
1134 protocol specification. Protocol TODO #11.
1136 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * Upgraded the protocol version to 1.1, updated protocol specs
1141 * Added the nickname as new argument to NICK_CHANGE notify and
1142 added it to protocol specs and implemented it to client and
1143 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1144 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1145 lib/silcclient/client_notify.c.
1147 * Added the killer's client ID to the KILLED notify and added
1148 it to protocol specs and implemented it to client and server.
1149 Protocol TODO #13. Affected files are silcd/command.c,
1150 silcd/packet_receive.c, packet_send.[ch],
1151 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1152 The killer's client entry is now returned to application in
1153 the `notify' client operation.
1155 * Fixed the Max Argument fields that had too large value set
1156 in the protocol specs. Protocol TODO #14.
1158 * Added the LEAVE command reply to return the ID of parted
1159 channel. Updated protocol specs and implemented it to the
1160 client and server. Protocol TODO #15. Affected files are
1161 silcd/command.c, lib/silcclient/command_reply.c. The channel
1162 entry is now returned to application in the `command_reply'
1165 * Rewrote the version SKE version checking in client libary
1166 and in server to use the silc_parse_version_string. Affected
1167 files are lib/silcclient/protocol.c, silcd/protocol.c.
1169 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1170 commands that was missing it, and updated protocol specs and
1171 the server implementation. Protocol TODO #10. The affected
1172 file is silcd/command.c.
1174 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1175 generic reply to a generic request (REQUEST flag), and
1176 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1177 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1178 to define the payload for DATA flag. Added the flags to
1179 the implementation. Protocol TODO #9. Affected file is
1180 lib/silccore/silcchannel.h.
1182 Changed the client library to return the message length
1183 to application as well in the channel_message and private_message
1184 client operations. Affected files are
1185 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1186 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1187 and lib/silcclient/client_ops_example.c.
1189 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1190 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1191 the channel. Updated protocol specs and impelemented this
1192 to client and server. Protocol TODO #6. Affected files are
1193 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1194 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1196 Added new options m and M to CMODE command in Irssi SILC
1197 client to set these modes.
1199 * Deprecated all administrative commands from SILC protocol
1200 since they are highly implementation specific commands.
1201 Updated protocol specs. Moved the old commands in
1202 implementations to private range of command types. Affected
1203 files are silcd/command.c, lib/silcclient/command.c and
1204 lib/silcclient/command_reply.c. Protocol TODO #8.
1206 * Fixed a bug in server where sending unknown command crashes
1207 the server. Affected file silcd/command.c.
1209 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1211 * Added SILC_PROTOCOLVERSION macro to check protocol version
1212 of a socket connection. The affected file is
1213 lib/silcutil/silcsockconn.h.
1215 * Added better error logging in rekey protocol. Affected file
1218 * Do not check public key types in SKE during rekey. Affected
1219 file lib/silcske/payload.c.
1221 * Fixed the rekey protocol with PFS, which was totally broken.
1222 Affected file silcd/protocol.c.
1224 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Some client implementations quit network by doing first LEAVE
1227 and then immediately SIGNOFF (like Bombyx). We now do check
1228 after a short time after LEAVE notify and check whether the
1229 client is still valid after LEAVE, and if not we remove it from
1230 cache. Affected file is lib/silcclient/client_notify.c.
1232 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1234 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1235 it's good not to have security holes here.
1237 * Fixed a negative refcount situtuation for the config context.
1238 Affected file is silcd/serverconfig.c.
1240 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1242 * ROBOdoc documented lib/silcutil/silcutil.h.
1244 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1246 * Optimized even more the SilcPacketContext structure. Now
1247 totally saved 16 bytes of memory per context after optimization.
1248 Affected files are lib/silccore/silcpacket.[ch].
1250 * Made strict checks for valid SILC IDs. Affected file is
1251 lib/silccore/silcid.c.
1253 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1255 * Changed the object argument for silc_cipher_register,
1256 silc_hash_register, silc_hmac_register and silc_pkcs_register
1257 to const. Affected files are lib/silccrypt/silccipher.[ch],
1258 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1260 * Changed the silc_get_username and silc_get_real_name to
1261 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1263 * Fixed the Irssi SILC Client to use the silc_get_username and
1264 silc_get_real_name insted of glib routines since the glib
1265 routines only corrupt stack. Fixes the Irssi SILC to work in
1266 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1268 * Fixed the Irssi to not use g_get_home_dir since it crashes
1269 or returns garbage on cygwin and corrupts stack. Added function
1270 get_home_dir to Irssi routines. Affected files are
1271 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1273 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1275 * Made some structure optimizations. SFTP memory FS MemFSEntry
1276 entry structure. Optimized SilcTask structure. Optimized
1277 SilcPacketContext structure.
1279 Affected files lib/silcsftp/sftp_fs_memory.c,
1280 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1282 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1284 * And yet again reverted back the config thing since Johnny
1285 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1288 * Fixed memory leaks from config object. Affected files are
1289 silcd/serverconfig.[ch].
1291 * Added support for adding new connections to the server in rehash.
1292 After rehash they take effect.
1294 Added support for changing the maximum allowed connections in
1295 rehash. The number can grow but going smaller is not supported.
1297 Added function silc_server_num_sockets_by_remote to the
1298 silcd/server_util.[ch].
1300 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1302 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1304 * Added preliminary checking during config parsing for a valid
1305 public/private key and removed further checks in the code.
1306 Affected files are silcd/serverconfig.[ch], server.c.
1308 * Moved functions silc_server_drop() and silc_server_daemonise()
1309 from server.c to silcd.c since they are stricly related to
1310 the application activity.
1312 * Reverted a small part of the automatic ref/unref since
1313 it caused a double unref in some situations. Affected
1314 files are silcd/silcd.[ch], server.c, serverconfig.c.
1316 * Added some .cvsignore files in the lib directory.
1318 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1320 * Fixed silc_net_gethostbyaddr to correctly resolve by
1321 address. Affected file lib/silcutil/silcnet.c.
1323 * Fixed the notify relaying to client. The HMAC to be used
1324 with relayed packets ws wrong and caused decryption failure
1325 at the client end. Affected file is silcd/packet_receive.c.
1327 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1329 * Created new branch silc_protocol_1_0_branch.
1331 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1333 * Changed the silc_server_config_* routines to be SilcServer
1334 independent. They are now officially application specific code
1335 and not part of generic server implementation. Affected files
1336 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1338 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Added automatic referencing of config context in the
1341 silc_server_config_alloc, and automatic unreferencing in the
1342 silc_server_config_destroy. Affected files are
1343 silcd/serverconfig.[ch], silcd/silcd.c.
1345 * Fixed the silc_log_quick handling in the logging routines.
1346 It didn't log quickly when it was TRUE. Affected file is
1347 lib/silcutil/silclog.c. Also the flush delay was set even
1348 if it was 0 in config file. Affected file is
1349 silcd/serverconfig.c.
1351 * Added support for changing key pair of the server in rehash.
1352 Affected file silcd/server.c.
1354 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1356 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1357 too early, before getting the channel entry. Affected file
1358 is silcd/packet_receive.c.
1360 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1362 * Added functions silc_server_config_[ref/unref], these are used
1363 to prevent that the config object is destroyed.
1365 No longer directly affect global variables silc_log_quick and
1366 silc_log_delay, they are first cached inside the config object
1367 and then applied with silc_server_config_setlogfiles().
1369 silc_server_config_set_defaults() is now internal to
1370 serverconfig.c, there are no reasons to show this internal stuff
1373 Affected files are silcd/serverconfig.[ch].
1375 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1376 fprintf's to stderr, since some code may be executed again after
1377 the server went into the background. Affected files are
1380 * Added rehash support. Added function silc_server_rehash() that
1381 will perform all the basic tasks of the rehashing procedure.
1383 * Added command line option `-x, --hexdump'. This will enable the
1384 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1385 The option `--hexdump' implies `--debug'.
1387 * Fixed a bad bug in the logging APIs (silcutil library) where
1388 the application would crash after calling silc_log_reset_all().
1390 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1392 * Fixed the KICKED notify handling in client library to
1393 correctly remove the channel and all entries from the
1394 channel when I was kicked. This bug crashed the client.
1396 Fixed yet another but in KICKED notify handling to remove
1397 the kicked client correctly from the channel.
1399 Affected file is lib/silcclient/client_notify.c.
1401 * Fixed a minor bug in looking up correct client entry
1402 in KICKED notify in server. Affected file is
1403 silcd/packet_receive.c.
1405 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1406 sources correctly to distribution. Fixes --with-gmp option.
1408 * Removed the manual rehashing from ID Cache, and changed it
1409 to use the SILC Hash Table's auto rehash feature. Affected
1410 file is lib/silccore/silcidcache.c.
1412 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1414 * Fixed a bug in the silc_client_nickname_format function that
1415 handles the multiple same nickname formatting. Two clients
1416 with same nickname caused problems after the first one left
1417 and rejoined. It didn't format the nickname correctly.
1418 Affected file is lib/silcclient/idlist.c.
1420 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1422 * Don't change the topic if olod topic is same as new one.
1423 Affected file is silcd/packet_receive.c.
1425 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1427 * Added cross-reference support to the SILC Documentation
1428 generator. All types across all HTML files are now cross-
1429 referenced. Affected files util/robodoc/generator.c and
1430 scripts/silcdoc/silcdoc.
1432 * Added file lib/silcutil/silctypes.h to include all the
1433 arithmetic type definitions and some macros. Removed
1434 includes/bitmove.h and moved macros to silctypes.h.
1436 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1438 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1440 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1442 * Added `type' argument to silc_id_payload_parse_id function which
1443 now returns the type of the ID to the sent pointer. Affected
1444 file is lib/silccore/silcid.[ch].
1446 * Added check for CMODE_CHANGE notify type that mode change is
1447 allowed by the sender. Affected file silcd/packet_receive.c.
1449 * Added check for CUMODE_CHANGE notify type that mode change is
1450 allowed by the sender. Affected file silcd/packet_receive.c.
1451 Added the ID type as CUMODE_CHANGE notify type as argument
1452 to the `notify' client operation. Affected files are
1453 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1455 * Added function silc_client_add_server to the client library.
1456 Added support for resolving also channel and server info when
1457 received unknown entity in notify packet. Affected files are
1458 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1460 * Added function silc_command_get_status to return the command
1461 status from the command reply's argument payload. Affected files
1462 are lib/silccore/silccommand.[ch].
1464 * Added check for KICKED notify type that the kicking is
1465 allowed by the client. Affected file silcd/packet_receive.c.
1467 * Created function silc_get_input which can be used to get input
1468 (echo on or off) from user on command line. Affected files are
1469 lib/silcutil/silcutil.[ch].
1471 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1473 * Optimized silc_server_packet_relay_to_channel function.
1474 Added new function silc_channel_message_payload_encrypt which
1475 can be called directly if channel message payload needs to
1476 be encrypted and is already encoded (no need to call _encode
1477 function). Packet relaying is now done by router without any
1478 extra memory allocations. Affected files are
1479 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1480 silcd/packet_send.c.
1482 * Fixed the INVITE notify handling. It took wrong arguments
1483 as invite list and invite delete. Affected file is
1484 silcd/packet_receive.c.
1486 * Added check for TOPIC_SET notify type that the topic change is
1487 allowed by the client. Affected file silcd/packet_receive.c.
1489 * Added check for INVITE notify type that inviting is allowed by
1490 the client. Affected file silcd/packet_receive.c.
1492 * Changed the silc_server_client_on_channel to return the
1493 SilcChannelClientEntry as well. Moved the function
1494 silc_server_check_cmode_rights to server_util.[ch].
1495 Affected files are silcd/server_util.[ch], silcd/command.c.
1497 * Added function silc_server_check_umode_rights to check whether
1498 changing client's user mode is allowed. Added check for
1499 UMODE_CHANGE notify type that the umode change is allowed
1500 by the client. Affected files are silcd/server_util.[ch],
1501 silcd/packet_receive.c and silcd/command.c.
1503 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1505 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1506 ID length. It ignored that ID can be IPv6 based as well.
1507 Affected file lib/silccore/silcpacket.h.
1509 * Fixed the silc_id_id2str and silc_id_str2id to take the
1510 IPv6 address offset's into consideration. Affecte file is
1511 lib/silccore/silcid.c.
1513 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1515 * Fixed the internal Unix scheduler functions to check for
1516 NULL context they may receive. The affected file is
1517 lib/silcutil/unix/silcunixschedule.c.
1519 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1521 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1522 can specify different directory with --home command line
1523 parameter. Affected files irssi/src/silc/core/client_ops.c,
1526 * SILC-specific commands aren't now executed if the active server
1527 isn't of SILC-type, so there won't be problems with having
1528 IRC and SILC protocol support in same client. Affected files
1529 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1532 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1534 * Improved the signal support in SILC Schedule. Added new
1535 function silc_schedule_signal_call which is used by application
1536 to mark a signal to be called. It is now safe to perform
1537 any kind of tasks in signal callbacks since it is guaranteed
1538 that the application specified signal callback is called
1539 after the signal is over. Affected files are
1540 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1542 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1544 * Added `name' field to SilcChannelPrivateKey to represent
1545 application given name for the key. Moved also the context from
1546 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1547 Added the `name' argument also to the function
1548 silc_client_add_channel_private_key.
1550 Added function silc_client_current_channel_private_key to set the
1551 current channel private key in use.
1553 Added "change" command to KEY command which can be used to change
1554 the current channel private key. Bound the command also to
1555 alt+K (Alt+Shift+k).
1557 Also affected files lib/silcclient/client_channel.c,
1558 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1560 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1562 * Added silc_rng_get_byte_fast function in to the
1563 lib/silccrypt/silcrng.[ch].
1565 * Changed the interface of silc_packet_assemble and the
1566 silc_packet_send_prepare. If silc_packet_assmble is now
1567 called the application does not call silc_packet_send_prepare
1568 because the library will call it automatically. These
1569 interfaces now also return a reference to the outgoing buffer
1570 which includes the assembled packet, which the application can
1571 use to encrypt the packet.
1573 Affected files are lib/silccore/silcpacket.[ch],
1574 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1575 silcd/packet_send.c, server_backup.c and packet_receive.c.
1577 * Fixed a packet sending bug on very high load, where outgoing
1578 packet queue wasn't handled correctly and packets got corrupted.
1579 Affected files are lib/silcutil/*/silc*sockconn.c,
1580 lib/silcclient/client.c and silcd/server.c.
1582 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1584 * Added macro SILC_PACKET_DATALEN which can be used during
1585 packet assembling to check whether the data to be added to
1586 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1587 len is truncated until it fits it.
1589 Added checks for maximum length of channel message payload and
1590 private message payload also.
1592 Added checks for maximum packet length in server and in
1595 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1596 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1597 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1598 lib/silcclient/client_prvmsg.c.
1600 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1602 * Added silc_server_packet_queue_purge call to the
1603 silc_server_disconnect_remote to assure that all data in the
1604 queue before disconnecting is sent to the network. Affected
1605 file silcd/server.c.
1607 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1609 * Added the deleting of server's own ID cache entry to the
1610 silc_server_free function. Free also everything else that
1611 has been allocated in silc_server_init. The affected file
1614 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1616 * Added functions silc_parse_version_string, silc_version_to_num,
1617 and silc_ske_parse_version to parse SILC protocol style version
1618 strings. Affected files lib/silcutil/silcutil.[ch] and
1619 lib/silcske/silcske.[ch].
1621 * Added new configuration params: version_protocol, version_software
1622 and version_software_vendor to specify what version the remote
1623 host must at least be to be able to connect to server. The vendor
1624 string can be regex matched too. Added new function
1625 silc_server_connection_allowed to check maximum number of allowed
1626 connections, and allowed versions for incoming connections.
1627 Affected files are silcd/server.c, server_util.[ch] and
1630 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1632 * Added preliminary support for signals in scheduler. The
1633 signals we care about are now blocked always when the scheduler
1634 is locked. This way we can synchronise the use of signal with
1635 scheduler. It is guaranteed that when signal occurs the scheduler
1636 is not locked, and thus new tasks can be safely added to the
1639 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1640 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1641 Added new platform specific routines
1642 silc_schedule_internal_signals_[un]block and
1643 silc_schedule_internal_signal_[un]register.
1645 Added new functions to SILC Schedule API:
1646 silc_schedule_signal_[un]register. Each signal that application
1647 is going to use should be registered to the scheduler.
1649 Affected files are lib/silcutil/silcschedule.[ch],
1650 lib/silcutil/*/silc*schedule.c.
1652 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1654 * Check for unauthenticated client and server in the
1655 silc_server_new_client and silc_server_new_server functions.
1656 Affected file silcd/packet_receive.c.
1658 * Added function silc_string_is_ascii to check whether given
1659 string is 7-bit ASCII string. Affected files are
1660 lib/silcutil/silcutil.[ch].
1662 * Added function silc_id_is_valid_server_id into the
1663 silcd/serverid.c and added checking for valid Server ID's in
1664 silc_server_new_server. The Server ID must always be based
1665 on the server's public IP address.
1667 * Added logging of DISCONNECT packet message in the server.
1668 Affected file silcd/server.c.
1670 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1672 * Changed all library interfaces that use Global RNG to also
1673 accept SilcRng as argument. Affected files are
1674 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1675 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1676 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1677 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1678 lib/silccrypt/rsa.c.
1680 * Added function silc_pkcs_generate_key to the
1681 lib/silccrypt/silcpkcs.[ch] for applications so that they
1682 don't need to do pkcs->pkcs->init calls anymore.
1684 * Remove SilcSocketConnection from the SFTP API since it really
1685 wasn't needed there. The application has the information
1686 saved in its contexts anyway and the SFTP layer doesn't need
1687 know about it. Affected files lib/silcsft/silcsftp.h and
1688 lib/silcsftp/sftp_[server/client].c.
1690 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1691 The SilcSimContext is not SilcSim.
1693 * Fixed possible buffer overflows in silc_id_render in the
1694 lib/silcutil/silcutil.c.
1696 * On EPOC the global crypto module lists are not used at all
1697 in the crypto library. Added support for using the constant
1698 algorithm list on EPOC. Affected files are
1699 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1702 * Fixed the handling of third parameter of KICKED notify, since
1703 it was mistakenly updated to SILC Protocol 1.0 even though it
1704 is to be included in 1.1. Since it is not in 1.0 it is not
1705 mandatory, and this fix now handles it only if it is provided,
1706 and it is not error if it is not provided. Affected file
1707 lib/silcclient/client_notify.c.
1709 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1711 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1712 client. Affected file irssi/src/silc/core/client_ops.c.
1714 * Merged with Irssi 0.8.4 from irssi.org CVS.
1716 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1718 * Check for valid socket connection in client entries before
1719 sending any messages. Fixes a crash, but doesn't fix some
1720 other underlaying bug that is lurking there. Affected
1721 file silcd/packet_send.c.
1723 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1725 * $usermode, $cumode and $cumode_space expandos shouldn't do
1726 anything with non-SILC server records. Affected file
1727 irssi/src/silc/core/silc-expandos.c
1729 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1731 * Fixed the silc_net_check_[host/local]_by_sock to support
1732 IPv6 bound sockets as well. Now they can return IPv6 addresses
1733 as well. Affected file lib/silcutil/silcnet.c.
1735 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1736 Affected lib/silcutil/unix/silcunixnet.c.
1738 * Fixed ID rendering (at least on some platforms, not NetBSD)
1739 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1741 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1743 * Added silc_hash_public_key and silc_hash_public_key_compare
1744 functions to be used with SilcHashTable. They can be used to
1745 hash public keys and compare public keys in hash table. Affected
1746 file lib/silcutil/silcutil.[ch].
1748 * Added support for specifying multiple public keys for Client
1749 connection section in server configuration file. This makes it
1750 possible to accept multiple public keys from same host, or to
1751 make a section that accepts any incoming host, and have the
1752 accepted public keys listed in the section.
1754 Added functions silc_sever_[find/get]_public_key, added the
1755 support for this actually to all connection sections but only
1756 the Client section is currently allowed to specify multiple
1759 Affected files are silcd/server.c, server_internal.h,
1760 command.c, protocol.c, server_util.[ch], packet_receive.c.
1762 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1764 * Merged Irssi 0.8.2 from irssi.org CVS.
1766 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1768 * If silc_debug is TRUE, also output standard logging messages
1769 to stderr with the debug output.
1771 Made silc_log_reset_all() flushing all channels before returning.
1772 Also fixed some documentation typos.
1774 Affected files are lib/silcutil/silclog.[ch].
1776 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1778 * Fixed the server to check correctly the amount of connections
1779 from single host, by checking also the type of the connection.
1780 Fixed also the comparison of number of connections and number
1781 of allowed connections. Affected files are silcd/server.c,
1784 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1786 * Fixed the USERS command reply to save the user's mode on the
1787 channel as well. Fixed JOIN command reply to check whether a
1788 client is on channel already and not join it twice. Affected
1789 file lib/silcclient/command_reply.c.
1791 * Added new file silc-expandos.c into irssi/silc/core/ to return
1792 various stuff for various signal for the statusbar etc. updating.
1793 Now Irssi SILC client prints channel user modes etc. on the
1796 * The user mode (like server/router operator changes) is now shown
1797 on the Irssi SILC client's statusbar. The affected files are
1798 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1800 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1802 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1803 to SILC_SCHEDULE_[UN]LOCK macros.
1805 * Added more error printing to logs in server code. Affected
1806 files silcd/server.c and silcd/protocol.c.
1808 * Fixed -S option parsing in Irssi SILC Client. Affected file
1809 irssi/src/silc/core/silc-core.c.
1811 * Added silc_buffer_alloc_size function. Affected file is
1812 lib/silcutil/silcbuffer.h.
1814 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1816 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1817 constants. Affected files in
1818 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1821 * Changed the internal SFTP Memory FS table to const. Affected
1822 file lib/silcsftp/sftp_fs_memory.c.

1826 * Fixed the buffer formatting and unformatting routines to
1827 check the size of 64 bits types with sizeof(). Affected
1828 file is lib/silcutil/silcbuffmt.c.
1830 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1834 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1836 * Changed all integer type names:
1837 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1838 to avoid collisions with other libraries using same type names
1841 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1843 * Added `prefer_ipv6' argument to the functions
1844 silc_net_gethostbyname[_async]. If it is TRUE it will return
1845 IPv6 address over IPv4. If FALSE IPv4 address is returned
1846 even if IPv6 address was found. Affected files
1847 lib/silcutil/silcnet.[ch].
1849 * Added support silc_net_create_connection[_async] to fallback
1850 to IPv4 address if IPv6 address could not be used (like if
1851 it doesn't work on a specific system). Affected file in
1852 lib/silcutil/unix/silcunixnet.c.
1854 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1856 * Added silc_schedule_reinit function to do the enlarging
1857 of the max tasks handling capabilities of the scheduler.
1858 Affected files lib/silcutil/silcschedule.[ch].
1860 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1862 * Added automatic extern "C" { ... } for C++ compilers so the
1863 application does not need to define them. Affected file
1864 includes/silcincludes.h.
1866 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1867 old name went against naming convention. Applications now
1868 include "silcclient.h" instead of "clientlibincludes.h".
1869 Removed includes/clientlibincludes.h, it is redundant now.
1871 * Renamed includes/version.h to silcversion.h.
1873 * Added really preliminary support for OS/2 into the util
1874 library. Only thread & mutex API is implemented, others
1875 are still to be implemented. Created the lib/silcutil/os2/
1876 directory. Created also file includes/silcos2.h.
1878 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1883 includes/silcbeos.h.
1885 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1887 * Added proper initializations to silc's irssi code, so it's
1888 now possible to load it as module. Affected files
1889 irssi/src/silc/core/silc-core.c,
1890 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1892 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1894 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1897 * Fixed the silcdoc document generator to correct generate
1898 docs from all kinds of filenames. Affected files are

1909 * Added `user_count' to the SilcChannelEntry which now tells the
1910 number of users on the channel. The user count is now saved
1911 in normal server of global channels as well. Affected files
1912 silcd/server.c, idlist.h, packet_receive.c and command.c.
1914 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1915 include file utility functions.
1917 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1918 instead of calling directly OS routines.
1920 * Fixed NICK change printing in Irssi SILC Client. Fixed
1921 KICKED notify printing in Irssi SILC Client. Affected file
1922 irssi/src/silc/core/client_ops.c.
1924 * Fixed a NICK change bug in client library, to not recreate the
1925 client_entry->channels hash table everytime nick is changed.
1926 Affected file lib/silcclient/client.c.
1928 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1930 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1931 the SKE interface a bit.
1933 * Fixed padding problem in PKCS#1. The padding was not actually
1934 random since the random number generator was used incorrectly.
1935 This security bug affects only when encrypting with PKCS#1, and
1936 it is not currently used at all in SILC. SILC only use signing
1937 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1939 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1943 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1945 * Send the auto-nicking NICK command in client library with
1946 little timeout after connecting. The affected file is
1947 lib/silcclient/client.c.
1949 * Added following new config file settings:
1950 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1951 key_exchange_timeout, conn_auth_timeout, connections_max,
1954 Implemented all the new config settings handling in the server.
1956 Optimized the use of SKE Mutual flag usage. Use it only
1957 if connection authentication protocol is not based in public
1960 Renamed all SilcServerConfigSection* to SilcServerConfig*
1961 to have a bit shorter names.
1963 Affected files silcd/serverconfig.[ch], server.[ch], and
1966 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1992 Affected files are silcd/serverconfig.[ch].
1994 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1996 * Fixed command line parameter handling. All SILC initialization
1997 is now done in silc_core_init() which also fixes autoconnecting
2000 Affected files irssi/src/silc/core/silc-core.c,
2001 irssi/src/fe-text/silc.c.
2003 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2005 * Added new configuration options and blocks:
2006 keepalive_secs, reconnect_count, reconnect_interval,
2007 reconnect_interval_max, reconnect_keep_trying and
2008 require_reverser_lookup. Added ConnectionParam block, and
2009 implemented the connection parameters when connecting as
2010 initiator and when accepting connections as responder.
2012 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2013 whether given configuration value has been given already.
2015 Affected files silcd/serverconfig.[c], server.[c].
2017 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2018 algorithm parts and created new file silcalgs.conf, that
2019 is now included from the example_silcd.conf.in.
2021 * Optimized the silc_server_connect_to_router_second to take
2022 the connection configuration object from the SilcServerConnection
2023 object instead of finding it during the connecting phase.
2024 Added the configuration object to SilcServerConnection struct.
2025 Affected files silcd/server_internal.h, server.c.
2027 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2029 * Add the client on channel after it was resolved at the
2030 channel message receiving, and it was not already on the
2031 channel. Affected file lib/silcclient/client_channel.c.
2033 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2035 * Fixed the public key authentication to allocate always the
2036 destination signature buffer instead of using static buffer.
2037 Affected file silcd/protocol.c.
2039 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2041 * Unified the serverconfig.[ch]'s helper function interface.
2042 Affected file silcd/serverconfig.[ch].
2044 * Removed doc/example_silc.conf.in since it is redundant.
2045 The make install will now install irssi/silc.conf file.
2047 * Added new Passphrase and Publickey authentication methods to
2048 config file, allowing both public key and passphrase based
2049 authentication to be set at the same time.
2051 Added `prefer_passphrase_auth' setting in config file which
2052 can be used to set to prefer passwd auth if both passwd and
2053 public key is set. If not set, public key is preferred.
2054 This has effect only when being initiator (responder will try
2057 Added support for authentication with passphrase and public key
2058 at the same time. The passphrase is tried first always since
2059 it is faster to check.
2061 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2063 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2089 * Allow zero length channel messages inside the Channel Message
2090 Payload. Affected file lib/silccore/silcchannel.c.
2092 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2093 as header filenames.
2095 * Removed lib/silcclient/README and created HTML file
2096 lib/silcclient/silcclient_using.html, which is now included
2097 as part of Toolkit documentation.
2099 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2101 * Fixed CUMODE_CHANGE notify handling to change the mode of
2102 correct client. Affected file lib/silcclient/client_notify.c.
2104 * Make silc_rng_alloc fail if it cannot allocate the sha1
2105 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2107 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2109 * Fixed the file transfer's key agreement payload to include
2110 zero port also if the hostname is NULL because it could not
2113 Call file transfer monitor callback now also if error occurs
2114 during key agreement protocol.
2116 Changed the silc_client_file_send interface to return the
2117 SilcClientFileError instead of session id. The session ID
2118 is returned into pointer provided as argument.
2120 Check that the file exists locally before sending the
2121 file transfer request at all.
2123 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2125 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2126 error than can occur while key agreement protocol. Affected
2127 file lib/silcclient/silcapi.h.
2129 * Fixed the event_mode CMODE handler to not crash when mode
2130 is changed and +k mode is set in the channel. Affected file
2131 irssi/src/silc/core/silc-channels.c.
2133 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2134 SILC_LOG_WARNING to give out Warning and not Error. Affected
2135 file lib/silcutil/silclog.c.
2137 * Fixed the channel message payload decryption in the function
2138 silc_channel_message_payload_decrypt to not modify the original
2139 buffer before it is verified that the message decrypted
2140 correctly. Otherwise, next time it is called with correct
2141 channel key it won't encrypt since the payload is corrupted.
2142 Affected file lib/silccore/silcchannel.c.
2144 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2146 * Do not constantly resize the window. A fix patch by cras.
2147 Affected file irssi/src/fe-text/screen.c.
2149 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2151 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2152 Affected file lib/silcutil/silcnet.c.
2154 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2156 * Fixed a bug in hash table internal routine for traversing
2157 the table with foreach callback. The current entry may
2158 become invalid in the callback but it was referenced after
2159 the callback returned.
2161 Do not allow auto rehashing of hash table during the
2162 silc_hash_table_foreach operation, for same reasons as it is
2163 not allowed for SilcHashTableList. Affected files are
2164 lib/silcutil/silchashtable.[ch].
2166 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2168 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2169 Win32 DLL. extern's in header files are now declared with
2172 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2174 * Fixed private message handling. It used some old code that
2175 caused the client to crash. Affecte file is
2176 lib/silcclient/client_prvmsg.c.
2178 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2180 * Added function silc_client_add_channel,
2181 silc_client_replace_channel_id, and removed functions
2182 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2183 from client library.
2185 * Added cross reference of the joined channels to the
2186 SilcClientEntry, and changed the SilcChannelEntry's
2187 users list to SilcHashTable. The affected files are
2188 lib/silcclient/idlist.[ch].
2190 * Fixed a bug in hash table tarversing. While the hash table
2191 is traversed with SilcHashTableList the table must not be
2192 rehashed. It is now guaranteed that auto rehashable tables
2193 are not rehashed while tarversing the list. Also defined that
2194 silc_hash_table_rehash must not be called while tarversing
2195 the table. Added function silc_hash_table_list_reset that must
2196 be called after the tarversing is over. The affected files are
2197 lib/silcutil/silchashtable.[ch].
2199 * Changed all hash table traversing to call the new
2200 silc_hash_table_list_reset in server and in client library.
2202 * Added function silc_client_on_channel to return the
2203 SilcChannelUser entry if the specified client entry is joined
2204 on the specified channel. This is exported to application as
2205 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2207 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2209 * Fixed founder regaining problem with JOIN command on normal
2210 server. The notify for mode change must be sent always and
2211 not only if !cmd->pending. Affected file silcd/command.c.
2213 * Fixed the WHOWAS command's reply sending to support the
2214 lists correctly. Affected file silcd/command.c.
2216 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2218 * When sending JOIN command to router for processing the
2219 sender's old command identifier was not saved back to the
2220 sender's command context, fixed now. The affected file is
2223 * Create the key in JOIN command of the router did not return
2224 the channel key, added check for this. Affected file is
2227 * Fixed a channel ID update bug in JOIN command reply. Do
2228 not directly upgrade the ID but call the function
2229 silc_idlist_replace_channel_id if the ID was changed.
2230 Affected file silcd/command_reply.c.
2232 * Fixed memory leaks from command calling if it would fail.
2233 Affected file silcd/command.c.
2235 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2237 * Applied patches from cras:
2239 Memory leak fixes around libaries, irssi window resize fix,
2240 new silclist.h and silcdlist.h, all extern inline changed to
2243 * Removed dotconf from lib/dotconf, not needed anymore.
2245 * Removed TRQ from lib/trq, not needed anymore.
2247 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2248 with server connections. Later this will be configurable
2249 in config file after new config file is done. Affected file
2252 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2254 * Fixed a crash in server related to channel announcements.
2255 Affected file silcd/server.c.
2257 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2259 * Fixed memory leaks in silc_server_create_new_channel*
2260 functions. Affected file silcd/server.c.
2262 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2263 which ID was changed. This way the router will send the
2264 user list for the channel again, and server won't be in
2265 desync in some rare circumstances. Affected file is
2266 silcd/packet_receive.c.
2268 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2270 * Check for NULL socket pointer in the function
2271 silc_server_packet_send_to_channel_real. Affected file
2272 silcd/packet_send.c.
2274 * Fixed the BAN notify handling to correctly remove ban
2275 list. Affected file silcd/packet_receive.c.
2277 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2279 * Fixed some header addition to Toolkit distribution in
2280 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2282 * Added lib/silcclient/client_ops_example.h as an template
2283 file for application programmers to quickly start using
2284 the SilcClientOperation functions in their application.
2285 Updated the lib/silcclient/README as well to tell about this
2286 nice file made available.
2288 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2290 * Call silc_server_remove_from_channels when removing client
2291 entry when NO_SUCH_CLIENT_ID was received. Affected file
2292 is silcd/command_reply.c.
2294 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2296 * Added server & router operator statistics updating. Affected
2297 file silcd/packet_receive.c and silcd/command.c.
2299 * Fixed the SERVER_SIGNOFF notify handling on normal server
2300 not to save the history information for clients. Same was
2301 fixed earlier in remove_clients_by_server function, but not
2302 here. Affected file silcd/packet_receive.c.
2304 * Raised the default connection-retry count from 4 to 7 in
2305 server. Affected file silcd/server.h.
2307 * Cancel any possible reconnect timeouts when we start the
2308 key exchange. Affected file silcd/server.c.
2310 * Do not reconnect on connection failure when SCONNECT was
2311 given. Affected files silcd/server.[ch].
2313 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2315 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2317 * Fixed the NICK command to always give the unformatted
2318 nickname to the one giving the NICK command. If unformatted
2319 nickname is cached already it will be formatted and the
2320 local entry will always get the unformatted nickname.
2321 Affected file lib/silcclient/idlist.c.
2323 * Fixed some double frees from client library commands.
2324 Affected file is lib/silcclient/command.c.
2326 * Fixed CUMODE command in server to assure that no one can
2327 change founder's mode than the founder itself, there was a
2328 little bug. Affected file silcd/command.c.
2330 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2332 * Removed the SilcClientCommandDestructor from the client
2333 libary, it is not needed anymore. Affected files are
2334 lib/silcclient/silcapi.h, command[_reply].[ch],
2335 client_notify, idlist.c.
2337 * Fixed GETKEY command to first resolve client, and then
2338 resolve the server only if the client was not found, instead
2339 of resolving both at the same time. Affected file is
2340 lib/silcclient/command.c.
2342 * Added silc_client_start_key_exchange_cb and lookup the
2343 remote hostname and IP address before starting the key
2344 exchange with server. The affected file is
2345 lib/silcclient/client.c.
2347 * The server's public key is now saved using the IP address
2348 of the server and not the servername for the filename.
2349 The hostname public key filename is checked as an fall back
2350 method if the IP address based filename is not found.
2352 Fixed the GETKEY command to save the fetched server key
2353 in correct filename.
2355 Print the remote server's hostname now when new key is
2356 received during connection process. Affected file is
2357 irssi/src/silc/core/client_ops.c.
2359 * Return always our own public key to the client if it asks
2360 for it with GETKEY command. Affected file silcd/command.c.
2362 * Removed the use_auto_addr variable from default config
2363 file since it was in wrong section. Affected file is
2366 * Fixed TOPIC_CHANGE notification to not route it when it
2367 was sent using silc_server_send_notify_to_channel function.
2368 Affected file silcd/command.c.
2370 * Fixed silc_server_send_notify_kicked to send the kicker's
2371 Client ID also, it was missing. Affected files are
2372 silcd/command.c, silcd/packet_send.[ch].
2374 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2376 * Do not save client history information in SERVER_SIGNOFF.
2377 Fixes the bug in normal server that it does not detect
2378 the client becoming valid after the server becomes back
2379 online. Affected file silcd/server_util.c.
2381 * Added `sock_error' field into the SilcSocketConnection
2382 context. When error occurs during socket operation (read
2383 or write) the error is saved. Added also new function
2384 silc_socket_get_error to return human readable socket error
2385 message. Affected files are lib/silcutil/silcsockconn.[ch],
2386 lib/silcutil/unix/silcunixsockconn.c, and
2387 lib/silcutil/win32/silcwin32sockconn.c.
2389 * The server now prints the socket error message in the
2390 signoff for client. Affected file silcd/server.c.
2392 * Fixed the `created' channel information sending from router
2393 to server in JOIN command. Checks now whether the channel
2394 really was created or not and set it according that.
2396 Fixed the JOIN command to use the client entry's current
2397 ID during the joining procedure instead of the one it sent
2398 in the command (it is checked though), since it can change
2399 between the packet processing and command processing, and
2400 would just case unnecessary pain in the client end. Affected
2401 file silcd/command.c.
2403 * Fixed a channel key payload sending to use correct channel
2404 ID when the server was forced to change the channel's ID by
2405 router. Router sent the key payload with the old Channel ID.
2406 Affected file silcd/packet_receive.c.
2408 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2410 * Call silc_server_save_channel_key only if the key payload
2411 was provided in the JOIN command's command reply. Affected
2412 file silcd/command_reply.c.
2414 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2416 * Fixed silc_mp_sizeinbase to return the value correctly with
2417 MPI. Affected file lib/silcmath/mp_mpi.c.
2419 * Fixed the stop_server signal to correctly stop the scheduler
2420 and gracefully stop the server when SIGTERM or SIGINT signals
2421 are received. Affected file silcd/silcd.c.
2423 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2425 * Simple handling of TERM and HUP signals. Also added some log
2426 flushing call around. Affected file is
2429 * Fixed small bugs in silclog.c. Now buffering output will take
2430 effect after 10 seconds since startup: This will ensure that
2431 no important startup messages are lost. Also output redirection
2432 will preserve original format ([Date] [Type] message).
2433 Affected file is lib/silcutil/silclog.c.
2435 * Added two options to the config file, in the logging section:
2436 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2437 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2439 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2441 * Do not print the warning about log files not being initialized
2442 more than once to avoid excess logging. Affected file is
2443 lib/silcutil/silclog.c.
2445 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2446 the SIM copying in make install in Makefile.am.pre.
2448 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2450 * Rewritten silclog APIs. Globally interesting changes follows:
2451 silc_log_set_files() changed to silc_log_set_file().
2452 silc_log_set_callbacks() changed to silc_log_set_callback().
2453 ROBOdoc documented silclog header file.
2454 SilcLogCb now returns bool to wether inihibit the default
2455 handler or not (to keep the old behaviour return always TRUE).
2456 The new APIs should also fix the problem of the
2457 silcd_error.log file that was written in the current directory.
2460 Log files streams will remain opened after silc_log_set_file()
2461 call, means less CPU usage notably on high traffic servers.
2462 File streams are now full buffered, and flushed to the disk
2463 every 5 minutes, lesses HD activity and CPU usage.
2464 Messages can be redirected, allowing admins to configure
2465 one single logfile for all server messages.
2466 the silc_log_quick global variable to activate fast-logging.
2467 Affected files lib/silcutil/silclog.[ch]
2469 * Changed some code to conform new silclog APIs. Affected
2470 files are doc/example_silcd.conf.in, silcd/server.c
2471 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2474 * Fixed a memory leak that could occur in some situations.
2475 Affected file silcd/serverconfig.c.
2477 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2479 * Added the silc_client_del_client to remove the client from
2480 all channels as well. Affected file lib/silcclient/idlist.c.
2482 * Fixed the client library to correctly remove the client
2483 from all channels when the client entry is being destroyed.
2484 Affected file lib/silcclient/client_notify.c, command.c.
2486 * Added auto-nicking support to the client library. If the
2487 applicatio now sets client->nickname it will be sent to the
2488 server after connecting by the library. This way for example
2489 SILCNICK (or IRCNICK) environment variables will have effect
2490 and always change the nickname automatically to whatever
2491 it is wanted. Affected file lib/silcclient/client.[ch].
2493 * Renamed silc_server_command_bad_chars to the
2494 silc_server_name_bad_chars and moved it to the
2495 silcd/server_util.[ch]. Added also new function
2496 silc_server_name_modify_bad to return nickname that
2497 includes bad characters as new nickname without those
2498 bad characters. This check and modify is now used in
2499 silc_server_new_client when the username is initially set
2500 as nickname, so it must be checked to be valid nickname.
2501 Affected file silcd/packet_receive.c.
2503 * The nickname length is now taken from the packet for real
2504 and not trusted to strlen() since it clearly can return
2505 wrong length for nickname including bad characters. This
2506 also applies to channel names. Affected file silcd/command.c.
2508 * Removed the lib/silcsilm/modules directory. Modules are now
2509 compiled into the lib/silcsim. Fixed the copying of the
2510 modules to follow symbolic links in Makefile.am.pre.
2512 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2514 * Fixed silc_string_regexify list creation. Fixes bugs with
2515 BAN and INVITE commands in server. The affected file is
2516 lib/silcutil/unix/silcunixutil.c.
2518 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Removed the command destructor entirely from the server's
2521 command and command reply routines. It is not needed, and
2522 its usage was buggy and caused crashes. Affected files are
2523 silcd/command[_reply].[ch].
2525 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Cancel protocol and NULL sock->protocol if timeout
2528 occurred during protocol. Affected file silcd/server.c.
2530 * Cancel protocol timeouts always before calling the final
2531 callback, to assure that after final callback is called
2532 no other state will be called for the protocol anymore.
2533 Affected file silcd/protocol.c.
2535 * Print error log if incoming connection configuration could
2536 not be found. Affected file silcd/server.c.
2538 * Fixed JOIN command to correctly save the founder mode
2539 to the client on normal SILC server, when the channel
2540 was created by the router. Affected file silcd/command.c.
2542 * Fixed LIST command (hopefully) to send correct reply
2543 packets. Affected file silcd/command.c.
2545 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * The silc_packet_receive_process now returns FALSE if the
2548 read data was invalid packet, and TRUE if it was ok.
2550 The server now checks that if unauthenticated connection
2551 sends data and its processing fails the server will close
2552 the connection since it could be a malicious flooder.
2554 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2556 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Make sure the warning about error opening a log file is
2559 printed only once and not everytime it fails (produces
2560 too much useless log). Affected file lib/silcutil/silclog.c.
2562 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2564 * Made the silc_server_daemonise() function more readable.
2565 Affected file silcd/server.c.
2567 * Pid file is now optional, the user may comment it out from
2568 the config file. Removed define SILC_SERVER_PID_FILE, we
2569 don't need a default any longer. Affected file
2570 configure.in.pre, lib/Makefile.am.pre.
2572 * Make some use of the pid file. The server now dies at startup
2573 if it detects a valid pid file on his path. The server would
2574 die anyway in this circumstance, because of the bind() failure.
2575 Affected file silcd/silcd.c.
2577 * No longer compiling lib/dotconf.
2579 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Fixed JOIN command parsing not to crash. Affected file
2582 lib/silcclient/command.c.
2584 * Fied the NICK_CHANGE notify to add the new client entry
2585 even it is resolved. This removes an <[unknown]> nick
2586 thingy bug in the client. Affected file is
2587 lib/silcclient/client_notify.c.
2589 * Do not try to allocate 0 bytes (efence does not like it)
2590 in lib/silccore/silccomand.c when encoding payload.
2592 * Do not take IRCNICK as nickname in Irssi SILC client since
2593 it is not possible to set nickname before hand connecting
2594 the server (TODO has an entry about adding auto-nicking
2597 * Changed the silc_server_command_pending to check whether
2598 there already exists an pending entry with the specified
2599 command, command identifier and pending callback. This is
2600 to fix IDENTIFY and WHOIS related crashes that may register
2601 multiple pending commands with same identifier. Affected
2602 file silcd/command.c.
2604 * Fixed the server to reconnect to the router even if it
2605 was already reconnecting and EOF was received. This to
2606 fix a possibility that the server wouldn't ever try to
2607 auto-reconnect to the router. Affected file silcd/server.c.
2609 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Fixed the server's password authentication to use the
2612 length of the locally saved password, and not the one
2613 sent in the packet. Affected file silcd/protocol.c.
2615 * Fixed same password authentication problem in the
2616 Authentication Payload handling routines in
2617 lib/silccore/silcauth.c.
2619 * Yet another password authentication problem fixed with
2620 channel password handling in silcd/command.c.
2622 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * If first character of string in silc_parse_userfqdn is '@'
2625 then do not parse it. Affected file is
2626 lib/silcutil/silcutil.c.
2628 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * Fixed minor bug in IDENTIFY command reply sending, which
2631 caused various weird problems during JOIN when it was
2632 resolving names for users. Affected file silcd/command.c.
2634 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * Fixed the IDENTIFY command reply sending to chech better valid
2637 clients. It was possible to send incomplete list of replies.
2638 Affected file silcd/command.c.
2640 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Added silc_client_command[s]_[un]register functions now to
2643 dynamically register the commands in client library. Removed
2644 the static table of commands. This allows the client library
2645 to call commands without causing the application to know about
2646 what commands library has called.
2648 Removed the INFO command reply kludge to detect when the command
2649 was called by library. Now library use its own command reply
2650 function for INFO command.
2652 Added function silc_client_command_call to call a command.
2653 Application can use it to call command, not access the structure
2656 Now all commands that are sent by the client library (not
2657 explicitly sent by application) use own command reply functions.
2659 Affected files around lib/silcclient/ and in
2660 irssi/src/silc/core/.
2662 * Fixed the WHOIS command reply sending to chech better valid
2663 clients. It was possible to send incomplete list of replies.
2665 Fixed the WHOIS and IDENTIFY to send the request to router
2666 if normal server did not do it and did not find any results.
2668 Affected file silcd/command.c.
2670 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Moved the internal data from SilcClient context into its
2673 own file, not accesible to application. Affected files
2674 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2675 and other files in client library.
2677 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Added doc/examples installation target in Makefile.am.pre.
2682 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2685 commands the found client entry will be removed from the
2686 cache, after notifying application about the error. Affected
2687 file lib/silcclient/command_reply.c.
2689 * Changed the /MSG to check for exact nickname user gave, and
2690 not let `nick' match `nick@host' if it is only one found. Now,
2691 user must type the exact nickname (like nick@host2) even if
2692 there are no more than one same nicks found. This is to avoid
2693 a possibility of sending nickname to wrong nickname since
2694 `nick' could match `nick@host'. Affected file is
2695 irssi/src/core/silc-servers.c.
2697 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2699 * Do not print "you are now server operator" or similar when
2700 giving /away command. Affected files are
2701 irssi/src/silc/core/client_ops.c, silc-servers.h.
2703 * Made the silc_server_command_pending_error_check to send
2704 the same command reply payload it received back to the
2705 original sender of the command. This way all arguments
2706 that was received by the server will be received by the
2707 client too. Affected file silcd/command.c.
2709 * Added the silc_idcache_add to return the created cache entry
2710 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2712 * Add global clients to expire if they are not on any channel.
2713 This is because normal server will never know if they signoff
2714 if they are not on any channel. The cache expiry will take
2715 case of these entries. This is done by normal servers only.
2716 The affected files are silcd/command_reply.c,
2717 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2719 * If server receives invalid ID notification for WHOIS or
2720 IDENTIFY and the ID exists in the lists, it is removed.
2721 Affected file silcd/command_reply.c.
2723 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2724 in client then client entry that it matches is searched and
2725 the nickname is printed on the screen for user. Affected
2726 file irssi/src/silc/core/client_ops.c.
2728 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2730 * Use cache entry expire time in the LIST command reply to
2731 purge old entries from the cache after the LIST command
2732 reply has been received. This way we don't have non-existent
2733 entries in the cache for too long. Affected file is
2734 silcd/command_reply.c.
2736 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * If we are normal server, and we've not resolved client info
2739 in WHOIS or IDENTIFY from router, and it is global client,
2740 we'll check whether it is on some channel. If it is not
2741 then we cannot be sure about its validity and will resolve it
2742 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2743 file silcd/command.c.
2745 * Search channel by name (if possible) rather than by ID
2746 in IDENTIFY command's command reply. Affected file is
2747 silcd/command_reply.c.
2749 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2752 Updated specs and implemented it. Affected file silcd/command.c,
2753 silcd/packet_send.c and silcd/packet_receive.c.
2755 * Implemented the <founder auth> payload handling in the JOIN
2756 command. If provided all conditions for channel joining
2757 except requirement to provide correct passphrase can be
2758 overrided by the channel founder. Updated the protocol specs.
2759 Affected file silcd/command.c.
2761 Added support for founder auth in JOIN command in client
2762 library. Fixed the parsing of the JOIN command now to support
2763 all options as they should be. The affected file is
2764 lib/silcclient/command.c.
2766 * Optimized the WHOIS and IDENTIFY commands to send the request
2767 to router only if it includes nicknames or other names. If
2768 they include only IDs then check the local cache first before
2769 routing. Affected file is silcd/command.c.
2771 * Added channels topic announcements. Affected file is
2772 silcd/packet_receive.c and silcd/server.c.
2774 * Fixed the silc_server_send_notify_topic_set to really destine
2775 the packet to channel. Affected file silcd/packet_send.c.
2777 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2778 library. Affected file lib/silcclient/client_notify.c.
2780 * Added UMODE announcements. Affected file silcd/server.c.
2782 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2784 * Memory leak fixes in:
2786 lib/silcutil/silcsockconn.c
2787 lib/silcske/silcske.c
2788 lib/silcske/groups.c
2790 lib/silccrypt/silcpkcs.c
2791 lib/silccore/silccommand.c
2792 lib/silccore/silcidcache.c
2797 * ROBOdoc documented the lib/silcske/groups.h file and a
2798 bit changed the interface for better.
2800 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2802 * Update the client entry context in the ID cache after
2803 nick change. Affected file lib/silcclient/command.c.
2804 Fixes the CUMODE command when regaining founder privileges,
2805 and a little WHOIS problem.
2807 * Fixed silc_net_gethostbyname to correctly call the
2808 inet_ntop. Affected file lib/silcutil/silcnet.c.
2810 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2812 * Added IPv6 support checking to the configure.in.pre, added
2813 also --enable-ipv6 option to override the check. Affected
2814 file configure.in.pre.
2816 * The silc_thread_create now calls the start function
2817 directly if threads support is not compiled in. Removes
2818 ugly #ifdef's from generic code. Affected files are
2819 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2821 * Added silc_net_gethostby[name/addr]_async to asynchronously
2822 resolve. Affected files are lib/silcutil/silcnet.[ch].
2824 * Added support for rendering IPv6 based server, client and
2825 channel IDs. Affected file lib/silcutil/silcutil.c.
2827 * Added support for creating IPv6 based server IDs. Affected
2828 file is silcd/serverid.c.
2830 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2832 * Added silc_net_gethostby[addr/name] into the
2833 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2834 routines. Added silc_net_is_ip[4/6]. Affected file is
2835 lib/silcutil/unix/silcunixnet.c. All routines that take
2836 address as argument now supports both IPv4 and IPv6 addresses.
2838 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2840 * Fixed LIST command reply sending in server. Affected file
2843 * Server now sends the kicker's client ID in the KICK notify
2844 to the kicked client. Affected file silcd/command.c.
2846 * The client library now parses the kickers client ID and
2847 UI displays it. Affected files lib/silcclient/client_notify.c
2848 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2850 * Made all payload parsing function prototypes consistent.
2851 They all take now const unsigned char * and uint32 pair as
2852 the payload data instead of SilcBuffer. Changes all around
2853 the source tree. Other unsigned char* -> const unsigned char*
2854 changes around the tree as well.
2856 * Optimized SFTP client and server packet sending not to
2857 allocate new buffer for each packet but to recycle the
2858 first allocated buffer. Affected files are
2859 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2861 * Optimized the SFTP client to use SilcList instead of
2862 SilcDList for requests, because it is faster. Affected file
2863 is lib/silcsftp/sftp_client.c.
2865 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2866 into lib/silccore/silcid.[ch].
2868 Renamed silcpayload.[ch] into silcargument.[ch].
2870 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * If client entry is deleted with active key agreement
2873 session, abort the session.
2875 The silc_client_abort_key_agreement now calls the completion
2876 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2878 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2881 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Don't use __restrict in older GCC's. Affected file is
2884 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2886 * silc_net_localhost now attempts to reverse lookup the
2887 IP/hostname. Affected file lib/silcutil/silcnet.c.
2889 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2890 command. It can be used to gain founder privileges at
2891 the same time when joining the channel.
2893 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2894 kicker's client ID as well. Updated protocol specs.
2896 Defined that the server must send SILC_COMMAND_IDENTIFY
2897 command reply with error status to client who sent
2898 private message with invalid client ID.
2900 Updated the protocol specification.
2902 * Added silc_server_send_command_reply to send any
2903 command reply. Affected file silcd/packet_send.[ch].
2905 * Added silc_id_payload_encode_data to encode ID payload
2906 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2908 * The server now send IDENTIFY command reply with error
2909 status if client ID in private message is invalid. Affected
2910 file silcd/packet_receive.c.
2912 * Save the server key file with server's IP address in
2913 the filename instead of hostname. The affected file is
2914 irssi/src/silc/core/client_ops.c.
2916 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2921 * Added libtool support for compiling shared objects in
2922 lib/silcsim. Affected file configure.in.pre and
2923 lib/silcsim/Makefile.am. Original patch by cras.
2925 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Pid file configuration, and server's config file fixes
2928 patch by toma. Updated CREDITS file.
2930 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2932 * Fixed silc_client_channel_message to not try to decrypt
2933 the message twice if it resolved the destination client
2934 information. This could cause of dropping one channel
2935 message. Affected file lib/silcclient/client_channel.c.
2937 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2940 lib/silcclient/client.c. This function is used when the SILC
2941 Client is run under some other scheduler, or event loop or
2942 main loop. On GUI applications, for example this may be
2943 desired to used to run the client under the GUI application's
2944 main loop. Typically the GUI application would register an
2945 idle task that calls this function multiple times in a second
2946 to quickly process the SILC specific data.
2948 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2950 * Fixed silc_server_drop() for dropping the supplementary
2951 groups as well, this could cause a security hole on some
2954 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2956 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2959 * Write PID file after dropping privileges. Added -F option
2960 to run server on foreground. A patch by debolaz.
2961 Affected files silcd/server.c, silcd/silcd.c.
2963 * Fixed MOTD to return the MOTD file server name. Affected
2964 file silcd/command.c.
2966 * Added INFO command reply handling to the Irssi SILC Client.
2967 Affected file irssi/src/silc/core/client_ops.c.
2969 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Fixed the silc_idcache_list_* routines to really support
2972 the dynamic list. Fixes a crash. Affected file is
2973 lib/silccore/silcidcache.c.
2975 * Fixed the LIST command reply to really call LIST command's
2976 pending callbacks. Affected file silcd/command_reply.c.
2978 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Update conn->local_entry->nickname after giving NICK
2981 command. Affected file lib/silcclient/command.c.
2983 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2985 * Added the [pid] option to the silcd configuration file
2987 Affected files: serverconfig.[ch] and silcd.c
2989 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Save fingerprint in WHOIS command reply in server.
2992 Affected file silcd/command_reply.c.
2994 * Fixed NICK commands pending callback registration.
2995 Affected file lib/silcclient/command.c.
2997 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Use ++server->cmd_ident when sending commands in server,
3000 instead of random number. Affected file silcd/command.c.
3002 * Fixed GETKEY command reply to call actually GETKEY pending
3003 command callbacks. Affected file silcd/command_reply.c.
3005 * A bit stricter check for nicknames. Check for same nickname
3006 in NICK command also. Affected file silcd/command.c.
3008 * Do not call INFO command everytime client ID changes, only
3009 during first connecting. Affected file lib/silcclient/client.c.
3011 * Set the new nickname only after successful command reply for
3012 NICK command is returned by server. Affected file
3013 lib/silcclient/command.c.
3015 * Remove nicknames from nicklist during server_signoff notify.
3016 Should fix /NAMES bit more. The affected file is
3017 irssi/src/silc/core/silc-channels.c.
3019 * Added `fingerprint' field to the SilcIDListData in the
3020 silcd/idlist.h to hold the fingerprint of the client's
3023 Send the fingerprint of the client's public key in WHOIS
3026 Affected files silcd/command.c, and silcd/idlist.[ch].
3028 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3029 create fingerprint from given data.
3031 * Show the fingerprint of the client's public key in WHOIS.
3032 Affected files irssi/src/module-formats.[ch] and
3033 irssi/src/silc/core/client_ops.c.
3035 * Format the multiple same nicknames also during JOIN and
3036 NICK_CHANGE notifys. Affected file is
3037 lib/silcclient/client_notify.c.
3039 * Do not print error on screen for invalid private message
3040 payload since it can come if someone is sending private
3041 messages with wrong key. Affected file
3042 lib/silccore/silcprivate.c.
3044 * Fixed multiple concurrent /PING crash. Affected file
3045 lib/silcclient/command.c.
3047 * Changed the wrong ID encoding. All IP addresses must be
3048 in MSB first order in encoded format. They were encoded
3049 wrong and was in LSB format. Affected files are
3050 silcd/serverid.c, lib/silcutil/silcutil.c.
3052 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3054 * Call the `connect' client operation through the scheduler
3055 in case of error. Affected file lib/silcclient/client.c.
3057 * Call the `failure' client operation even if the error
3058 occurred locally during a protocol. Affected file is
3059 lib/silcclient/protocol.c.
3061 * Added support of sending LIST command to router from normal
3062 server. This way normal server can get list of all channels
3063 in the network too. Fixed the channel list sending in the
3064 server too. Affected files are silcd/command.c, and
3065 silcd/command_reply.[ch].
3067 * Added silc_server_update_channels_by_server and
3068 silc_server_remove_channels_by_server. They are used during
3069 disconnection of primary router and in backup router protocol.
3070 Affected file silcd/server_util.[ch], silcd/server.c and
3071 silcd/server_backup.c.
3073 * Fixed channel adding to global list in IDENTIFY command
3074 reply in server. Affected file silcd/command_reply.c.
3076 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * If the incoming packet type is REKEY or REKEY_DONE process
3079 that packet always synchronously. Fixes yet another MAC
3080 failed error on slow (dialup) connections. Affected file
3081 lib/silcclient/client.c and silcd/server.c.
3083 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * Call check_version SKE callback for initiator too. Affected
3086 file lib/silcske/silcske.c.
3088 * Implemented fix for security hole found in the SKE that was
3089 fixed in the specification few days back; the initiator's
3090 public key is now added to the HASH value computation.
3091 Added backwards support for the old way of doing it too, for
3092 old clients and old servers. Affected file is
3093 lib/silcske/silcske.c.
3095 * Enabled mutual authentication by default in SKE. If initiator
3096 is not providing mutual authentication the responder will
3097 force it. This will provide the proof of posession of the
3098 private key for responder. The affected files are
3099 lib/silcclient/protocol.c and silcd/protocol.c.
3101 * Do not cache anymore the server's public key during SKE.
3102 We do mutual authentication so the proof of posession of
3103 private key is done, and if the server is authenticated in
3104 conn auth protocol with public key we must have the public
3105 key already. Affected file silcd/protocol.c.
3107 * Added new global debug variable: silc_debug_hexdump. If
3108 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3109 file lib/silcutil/silclog.[ch].
3111 * Fixed compilation warning due to char * -> const char *.
3112 Affected files lib/silcutil/silcnet.h, and
3113 lib/silccore/silcauth.[ch].
3115 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Fixed CMODE command when new channel key was created. If
3118 the creation failed the old key was removed. Next time giving
3119 same command would crash the server since the old key was
3120 freed already. Affected file silcd/command.c.
3122 * Fixed the silc_server_announce_get_channels to not crash
3123 on reconnect. Affected file silcd/server.c.
3125 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Added silc_log_set_debug_string function to set a regex
3128 string to match for debug output. Only the function names,
3129 or filenames matching the given debug string is actually
3130 printed. This way it is possible to filter out those debug
3131 strings that user is not interested in.
3133 Fixed a bug in silc_string_regexify.
3135 Affected files lib/silcutil/silclog.[ch], and
3136 lib/silcutil/unix/silcunixutil.c.
3138 * Changed the -d options in both server and Irssi SILC client
3139 to take the debug string as argument. Affected files
3140 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3142 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Added silc_hash_babbleprint to create a Bubble Babble
3145 Encoded fingerprint. The encoding is developed by Antti
3146 Huima (draft-huima-babble-01.txt), and it creates human

3155 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3157 * Fixed a security problem found in SKE. The initiator's
3158 public key too is now added to the HASH hash value creation
3159 which is signed by the responder to create the SIGN value.
3160 This will prevent anyone in the middle to lie to the responder
3161 about the initiator's public key. If this is done now, the
3162 man in the middle will get caught. Updated the protocol
3165 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Better installation directory handling. Configure module
3168 paths and other paths automatically to example_silc* files
3169 in doc/. A patch by toma.
3171 * Fixed compiler warning from MPI library, and from SILC RNG.

3201 * Added silc_pkcs_public_key_compare to compare two
3202 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3204 * Check that the client who set the founder mode on the
3205 channel is the same client that is giving the founder
3206 mode to itself. It is done by comparing the saved public
3207 key (it is saved even in the authentication is passphrase).

3218 * Fixed the silc_client_packet_parse to not to increase
3219 the packet sequence number if the conn->sock and the
3220 current socket connection is not same. This can happen
3221 for example during key agreement when the conn includes
3222 multiple socket connections (listeners). Affected file
3223 lib/silcclient/client.c.
3225 * The sender of the file transfer request now provides also
3226 the pointer (listener) for the key exchange protocol. If
3227 the listener cannot be created then it sends empty key
3228 agreement and lets the receiver provide the listener.
3230 Added `local_ip' and `local_port' arguments to the
3231 silc_client_file_send. If they are provided they are used,
3232 if not then it will attempt to find local IP address, if
3233 not found or bind fails then the remote client will provide
3236 Affected files are lib/silcclient/client_ftp.c and
3237 lib/silcclient/silcapi.h.

3246 of the client's public key (if the proof of posession of the
3247 corresponding private key is verified by the server).
3248 Updated to the protocol specification.
3250 * Added support of receiving the client's public key's
3251 fingerprint in command reply in client library. Affected
3252 file is lib/silcclient/command_reply.c, and
3253 lib/silcclient/idlist.[ch].
3255 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3312 preserve the WHOWAS info for the client. Affected file
3313 silcd/server_util.c.
3315 * Fixed SERVER_SIGNOFF notify handling in the server. The
3316 server is now able to process incoming SERVER_SIGNOFF notify
3317 for a server that it doesn't even know about. It will remove
3318 the clients provided in the notify. Affected file
3319 silcd/packet_receive.c.
3321 * Check for partial packet in data queue after every packet that
3322 was found from the queue. Return and wait for more data if
3323 there is partial data in queue. Affected file is
3324 lib/silccore/silcpacket.c.
3326 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3341 irssi/src/fe-common/silc/module-formats.[ch].
3343 * Wrote a help file for FILE command.
3345 * Added silc_rng_global_get_byte_fast to get not-so-secure
3346 random data as fast as possible. Random data is read from
3347 /dev/urandom if available and from the SILC RNG if not
3348 available. It is used in padding generation. Affected file
3349 lib/silccrypt/silcrng.[ch].
3351 * All packets in client library are now processed synchronously.
3352 Optimized packet processing a lot. Affected file
3353 lib/silcclient/client.c.
3355 * All server connection packets are processing synchronously
3356 now in server, to optimize packet processing. Affected file
3359 * Include files are installed now only in Toolkit distribution
3360 if make install is given. Affected files: all Makefile.am's.
3362 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3364 * Assure that silc_client_notify_by_server_resolve does not
3365 resolve the client information multiple times. If it cannot
3366 be found by the first it cannot be found at all. Affected
3367 file lib/silcclient/client_notify.c.
3369 * Fixed WHOWAS command reply calling. Affected file
3370 lib/silcclient/command_reply.c.
3372 * Removed all references to silc_idlist_get_client from the
3373 Irssi SILC client since that call is internal call used by
3374 the library. The Irssi SILC client will use now client
3375 retrieval functions found in silcapi.h.
3377 * Fixed a bug in resolving nickname info before sending
3378 private message. It used freed memory. Affected file
3379 irssi/src/silc/core/silc-servers.c.

3400 * Added silc_net_localip to return local host's IP address.
3401 Affected file lib/silcutil/silcnet.[ch].
3403 * If key exchange or rekey protocol is active for a connection
3404 parse all packets syncronously since there might be packets
3405 in packet queue that we are not able to process without first
3406 processing packets before them. Affected file silcd/server,
3407 lib/silcclient/client.c.
3409 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3410 whether library should continue processing the packet.
3411 Affected file lib/silccore/silcpacket.h.

3457 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3458 is incomplete and is being resolved, it won't be resolved
3461 Make sure also that USERS command reply does not resolve
3462 twice information. Affected file is
3463 lib/silcclient/command_reply.c.
3465 Make sure that silc_client_get_clients_by_list does not
3466 resolve twice same information.
3468 * Check for valid client->id in the silc_server_free_client_data.
3469 Affected file silcd/server.c.
3471 * Fixed /GETKEY nick@server not to crash if the server entry
3472 is not found. Affected file lib/silcclient/command.c.

3484 * Call the silc_server_udpate_servers_by_server in the
3485 primary router that comes back online in the backup resuming
3486 protocol. Otherwise it routes packets wrong. Affected file
3487 silcd/server_util.[ch], silcd/server_backup.c.
3489 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3492 lib/silcutil/silcbuffmt.[ch].
3494 * Redefined the SILC packet header to include the padding
3495 length. Affected file lib/silccore/silcpacket.[ch].
3497 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3498 length for maximum padding up to 128 bytes). Affected
3499 file lib/silccore/silcpacket.h.
3501 * Removed all backwards support for old 0.5.x MAC thingies.
3502 The SILC packet header change makes it impossible to be
3503 backwards compatible.
3505 * Send the ENDING packet with timeout in the backup resuming
3506 protocol. This is to assure that all routers has connected
3507 to the primary router. Affected file silcd/server_backup.c.
3509 * Changed the RNG to take the first IV from random data. It
3510 used to take it from zero actually. Changed the RNG also
3511 to use /dev/urandom during session. /dev/random is used
3512 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3514 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Changed the SILC packet header to have the first two bytes
3517 (the packet length) encrypted. Affected files aroung the
3518 code tree, lib/silccore/silcpacket.[ch]. Removed the
3519 SilcPacketCheckDecrypt callback. It is not needed anymore
3520 since the silc_packet_receive_process will determine now
3521 whether the packet is normal or special.
3523 * Implemented the unidirectional MAC keys. Affected files
3524 lib/silcske/silcske.c, silcd/protocol.c and
3525 lib/silcclient/protocol.c.

3532 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3534 * Allow backup router to announce servers. All servers
3535 announced by backup router are added to the global list
3536 automatically. Update hte server's socket to our primary
3537 router also when backup router announces a server.
3538 Affected file silcd/packet_receive.c.
3540 * Do not update the client->router in the function
3541 silc_server_udpate_clients_by_server if the client is on
3542 global list. We might fail to find any specific server
3543 for locally connected clients and local cell clients. They
3544 should still use the `from' and not `to' as client->router.
3545 This fixes backup router resuming protocol. Affected file
3546 silcd/server_util.c.
3548 * Decrease channel statistics count only if the channel
3549 deletion worked. Affected files are silcd/server.c and
3550 silcd/server_util.c.
3552 * Added silc_server_update_servers_by_server to update origin
3553 of all server entries. Used during backup router protocol.

3562 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Assure that router cannot reroute the same channel message
3565 to the sender. Affected file silcd/packet_receive.c.
3567 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3569 * Made better checks that the channel message is not sent
3570 to the router it came from. Affected file is
3571 silcd/packet_send.c. Fixed memory leak too.
3573 * Announce informations for incoming router connection, but
3574 only after checking if it is replaced by backup router.
3575 Affected file silcd/packet_receive.c.
3577 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Fixed the backup resuming protocol to work in multiple
3580 router environment. Affected file silcd/server_backup.c.
3582 * Route packet only to one router in the function
3583 silc_server_packet_send_to_channel. Affected file is
3584 silcd/packet_send.c.
3586 * Fixed silc_server_send_notify_dest to set the broadcast
3587 flag. Fixed the silc_server_send_notify_topic to actually
3588 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3589 Affected file silcd/packet_send.c.
3591 * Changed the SFTP Filesystem interface. Changed the
3592 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3593 the filesystem operation function. The SilcSFTPFilesystem
3594 is now a context that is allocated by all filesystem allocation
3595 functions and it already includes the operations structure
3596 and filesystem specific context. It is given as argument
3597 now to the silc_sftp_server_start. This made the interface
3598 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3599 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3601 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Changed the backup router adding and getting interfaces
3604 in the server. The router that will be replaced by the
3605 specified backup router is now sent as argument. Affected
3606 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3609 * Added silc_net_addr2bin_ne to return the binary form of
3610 the IP address in network byte order. Affected files

3613 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Check for existing server ID in silc_server_new_server
3616 and in silc_server_connect_to_router_final and remove the
3617 old entry if it exists. Affected file silcd/packet_receive.c,
3620 * Send the channel message always to only one router, either
3621 in upstream or downstream. Affected file is
3622 silcd/packet_send.c.
3624 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Wrote the definition of the backup resuming protocol to the
3627 protocol specification.
3629 * Removed one redundant channel key generation from normal
3630 server during joining procedure. Removed one redundant
3631 channel key sending from server to router during joining
3632 procedure. Affected file silcd/command.c.
3634 * Made minor bugfixes to the backup router resuming protocol.
3635 Affected file silcd/server_backup.c, server.c.

3645 primary router comes back online. Affected files
3646 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3647 and silcd/server_util.[ch].
3649 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Sleep two (2) seconds after sending QUIT command to server.
3652 Affected file lib/silcclient/command.c.
3654 * Assure that if outgoing data buffer is pending do not force
3655 send any data. Affected file silcd/packet_send.c.
3657 * Assure that if outgoing data buffer is pending do not force
3658 send any data. Affected file lib/silcclient/client.c.
3660 * Implemented the backup router support when the primary router
3661 goes down. The servers and routers can now use the backup
3662 router as new primary router without loosing connectivity.
3664 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3666 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3667 in the server to indicate disabled entry. All data read
3668 from the connection will be ignored and no data is sent
3669 for entry that is disabled. Affected files are
3670 silcd/idlist.h, silcd/server.c.
3672 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3674 * Created SFTP client and server test programs in the
3675 lib/silcsftp/tests directory.
3677 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3679 * Implemented memory filesystem (virtual filesystem) for
3680 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3683 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3685 * Implemented the SFTP (SSH File Transfer Protocol) to the
3686 lib/silcsftp. It includes SFTP client and SFTP server
3689 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Moved lib/silccore/silcprotocol.[ch] to the
3692 lib/silcutil library.
3694 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3695 take variable argument list pointer as argument. Affected
3696 file lib/silcutil/silcbuffmt.[ch].
3698 * Added silc_buffer_set function that is used to set data
3699 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3700 Affected file lib/silcutil/silcbuffer.h.
3702 * Changed various routines in the core library to use the new
3703 silc_buffer_set instead of allocating new buffer only for
3706 * Added 64-bit value formatting and unformatting support to the
3707 silc_buffer_[un]format routines. Affected file is
3708 lib/silcutil/silcbuffmt.[ch].
3710 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3711 to includes/bitmove.h.
3713 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3715 * Fixed channel user mode saving in client library. Affected
3716 file lib/silcclient/command[_reply].c.
3718 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Defined the file transfer to the SILC Protocol. Added
3721 new packet type SILC_PACKET_FTP and defined File Transfer
3722 Payload. The mandatory file transfer protocol is SFTP
3723 (SSH File Transfer Protocol). Affected file in addition
3724 of the internet draft is lib/silccore/silcpacket.h.
3726 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3727 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3728 is used as part of backup router protocol when the primary
3729 router of the cell is back online and wishes to resume
3730 the position as primary router.
3732 * Redefined the MAC generation keys in the protocol. The
3733 same key is not used anymore in both direction. Both
3734 direction will now use different keys for sending and
3735 receiving. This fixes a potential security flaw. This
3736 change causes incompatibilities in the protocol.
3738 * Redefined also the MAC computation from the packet.
3739 An packet sequence number is now added to the MAC
3740 computation. This prevents possible replay attacks against
3741 the protocol. This change too causes incompatibilities
3744 Added `sequence' field to the SilcPacketContext to hold
3745 the current sequence number for the packet.
3747 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3749 * Added `created' field to the SilcIDListData in the file
3750 silcd/idlist.h to indicate the time when the entry was
3753 * Added `created' field to the SilcChannelEntry too. Affected
3754 file silcd/idlist.h.
3756 * Added `creation_time' aguments to all the announcement functions
3757 in the server. If it is provided then only the entries that
3758 was created after the provided time frame are actually
3759 announced. Affected file silcd/server.[ch].
3761 * The protocol says that the Channel ID's IP address must be
3762 based on the router's IP address. Added check for this in
3763 the silc_server_new_channel when processing incoming New Channel
3764 Payload. Affected file silcd/packet_receive.c.
3766 * Print out the correct version with --version in SILC client.
3767 Affected file irssi/src/silc/core/silc-core.c.
3769 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Fixed WHOWAS command to check for completnes of the client
3772 entry always, not just when the command is coming from client.
3773 Affected file silcd/command.c.
3775 * Added new function silc_server_packet_queue_purge to purge the
3776 outgoing data queue to the network. After the function returns
3777 it is guaranteed that the outgoing packet queue is empty.
3778 Affected file silcd/packet_send.[ch].
3780 * Purge the outgoing packet queue in the rekey protocol's final
3781 callback to assure that all rekey packets go to the network
3782 before quitting the protocol. Affected file silcd/server.c.
3784 * Added silc_client_packet_queue_parse as similar function as
3785 in server to the client library. The affected file is
3786 lib/silcclient/client.c.
3788 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3790 * Splitted silcd/server.c and created silcd/server_util.[ch]
3791 for utility functions.
3793 * Added new socket flag SILC_SF_DISABLED to indicate that the
3794 connection is open but nothing can be sent to or received from
3795 the connection. Affected file lib/silcutil/silsockconn.[ch].
3796 The checking for disabled socket is checked in the low level
3797 silc_socket_write and silc_socket_read functions.
3799 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Allow only nicknames and channel names that fits into the
3802 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3804 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3806 * When processing JOIN command reply in server check that if
3807 the channel exists in our global list we'll move it the local
3808 list. Affected file silcd/command_reply.c.
3810 * Fixed the check whether client is joined on the channel already
3811 in JOIN command. Affected file lib/silcclient/command.c.
3813 * Fixed the JOIN command reply to check whether the channel
3814 already exists. Affected file lib/silcclient/command_reply.c.
3816 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Added silc_ske_status_string to map the SKE error numbers
3819 to readable strings. The affected files are
3820 lib/silcske/silcske[_status].[ch].
3822 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3824 * Do not show the private channels on the WHOIS channel list
3825 as it is not allowed by the protocol. The affected file is
3828 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * Assure that the packet length digged from the actual packet
3831 is something sensible in the silc_packet_decrypt_rest_special
3832 in lib/silccrypt/silcpacket.c.
3834 * Free and NULL the allocated pointer in silc_hmac_alloc if
3835 the HMAC allocation fails. The affected file is
3836 lib/silccrypt/silchmac.c.
3838 * Print the selected security properties to the log files in
3839 the server. Affected file silcd/protocol.c.
3841 * Add SKE's reference counter even if calling the completion
3842 callback manually. Otherwise it goes negative, although it
3843 does not cause any problems. The affected file is
3844 lib/silcske/silcske.c.
3846 * Remove the client entry with short timeout after giving the
3847 KILL command. Affected file lib/silcclient/command.c.
3849 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3850 case all found clients are already disconnected (WHOWAS would
3851 found them) in the server. Affected file silcd/command.c.
3853 * Update the last_receive (time of last data received) to be
3854 updated only when received private or channel message so that
3855 the idle time showed in WHOIS makes more sense.
3857 * Added boolean field `valid' in to the SilcClientEntry in the
3858 client library to indicate whether the entry is valid or not.
3859 This fixes the nickname change bug on channel when changing
3860 the nickname to be same than the old (like nick to Nick) the
3861 nickname formatter doesn't set the new nick anymore to Nick@host.
3862 Affected file lib/silcclient/idlist.[ch].
3864 * Now actually fixed the nickname changing on disconnection.
3865 Added new function silc_change_nick to the Irssi SILC Client.
3866 Affected file irssi/src/silc/core/client_ops.c,
3867 irssi/src/silc/core/silc-nicklist.[ch].
3869 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Check that the public key exists in the GETKEY command before
3872 trying to encode it. Affected file silcd/command.c.
3874 * Print some notifications on received public keys with GETKEY
3875 command in the Irssi SILC Client. Affected files are
3876 irssi/src/fe-common/silc/module-formats.[ch],
3877 irssi/src/silc/core/client_ops.c.
3879 * Use IDENTIFY command to resolve the server information in the
3880 GETKEY command instead of INFO command. Affected file
3881 lib/silcclient/command.c.
3883 * All command reply functions in the client library now calls
3884 the pending command reply callbacks even if an error has
3885 occurred. The server has done this a long time and now it was
3886 time to move the client library to this as well. Now all
3887 errors can be delivered back to the pending command reply
3888 callbacks if necessary. Affected files are
3889 lib/silcclient/command[_reply].[ch].
3891 * Change the nickname on disconnection back to the username
3892 because in reconnect the server will enforce it to it anyway.
3893 Affected file irssi/src/silc/core/silc-servers.c.
3895 * Fixed a config file parsing bug in the Irssi SILC client.
3896 Affected file irssi/src/silc/core/clientconfig.c.
3898 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * When printing the channel mode on JOIN, verify that the
3901 channel key and channel's HMAC are valid. Affected file
3902 irssi/src/silc/core/client_ops.c.
3904 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3906 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3907 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3908 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3910 * Removed channel key rekey task deleting from the function
3911 silc_server_save_channel_key. Affected file silcd/server.c.
3912 Added explicit timeout task context instead that is used to
3913 delete the task if we are registering a new task before the
3914 new task has elapsed.
3916 * When channel key rekey occurs the client library now saves
3917 the old channel key for a short period of time (10 seconds) and
3918 is able to use it in case some is still sending channel
3919 messages encrypted with the old key after the rekey. Affected
3920 file lib/silcclient/[idlist.h|client_channel.c].
3922 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3924 * Added check to the silc_server_new_id_real to not accept
3925 new ID if it is the sender's own ID. Affected file is
3926 silcd/packet_receive.c.
3928 * Assure that we do not announce ourself or the one we've
3929 sending our announcements when we're router and are announcing
3930 servers to our primary router. Affected file silcd/server.c.
3932 * Fixed silc_server_command_identify_check_client to assemble
3933 correct WHOIS packet. It send corrupted WHOIS packet and
3934 caused problem with router to router connections. Affected
3935 file silcd/command.c.
3937 Fixed also silc_server_command_whois_check the same way
3938 as for the IDENTIFY command.
3940 * Added new SilcIDListStatus to the server in the SilcIDListData
3941 structure. The status now includes the current status of
3942 the entry (like registered, resolved etc.). Affected file
3943 silcd/idlist.[ch]. Defined a bunch of different status types
3944 as well. This replaced the old boolean registered field as well.
3946 Added resolve_cmd_ident field to the SilcClientEntry structure
3947 too so that if the entry is for example being resolved so
3948 another command may attach to the same pending command reply
3949 without requiring to resolve the same entry again. This concept
3950 should optimize the WHOIS and the IDENTIFY resolving under
3951 heavy load by taking away unnecessary resolving for entries
3952 that are being resolved already.
3954 Added support for adding multiple pending commands for one
3955 command idenfier. Affected file silcd/command[_reply].[ch].
3957 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3958 before deleting the data. Otherwise the hash table will have
3959 freed data in comparison functions. Affected file is
3960 silcd/command_reply.c.
3962 * Fixed silc_idlist_replace_client_id to add the new entry to
3963 the cache with NULL nickname. Otherwise there will be invalid
3964 memory as the nickname after the nickname is freed. Affected
3965 file silcd/packet_receive.c.
3967 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3968 saved into wrong slots because the previous number of entries
3969 was not taken into account. Affected file silcd/idlist.c.
3970 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3972 * If we are router and we receive JOIN notify to a channel that
3973 does not have any users then notified client is marked as the
3974 channel founder, as it is it. The affected file is
3975 silcd/packet_receive.c
3977 * Added to the extended hash table API's table_del_*ext functions
3978 the destructor as argument too, so that the caller can decide
3979 which destructor to use or whether to use destructor at all.
3980 Affected file lib/silcutil/silchashtable.[ch].
3982 * Fixed ID Cache purging. It actually deleted the entries from
3983 the hash table after the data was freed. The hash table ended
3984 up comparing freed memory. The affected file is
3985 lib/silccore/silcidcache.c.
3987 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3989 * Fixed Irssi SILC client's KILL command's HELP syntax.
3991 * The USERS command now resolves the detailed user information
3992 if the userinfo field is missing. Affected file is
3993 lib/silcclient/command_reply.c.
3995 * Do not print error in silc_file_read if the read file does
3996 not exist. Just silently return NULL. Affected file is
3997 lib/silcutil/silcutil.c.
3999 * Fixed the silc_log_output to not wine about NULL filename
4000 and to not create some bogus " " filename. Affected file is
4001 lib/silcutil/silclog.c.
4003 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Fixed various printing bugs on the user interface in the
4006 Irssi SILC Client. Minor changes that were forgotten from
4009 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4011 * Fixed the configure.in.pre and the compilation and distribution
4012 environment to support the new autoconf 2.52. That version is
4013 now required to compile the CVS trunk.
4015 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4017 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4018 to generally parse user@fqdn format strings. Affected file
4019 lib/silcutil/silcutil.c.
4021 * Added nickname_format and nickname_force_format fields to the
4022 SilcClientParams structure. The first one defines the format
4023 for the nicknames that the library will enforce if the receives
4024 multiple same nicknames. The second one is boolean value and
4025 can be used to force the library to always enforce the format
4026 to the nicknames regardles whether there are multiple nicknames
4027 or not. This configurable formatting was employed to flexibly
4028 support accessing multiple nicknames from the user interface.
4029 The userinterface can now set the nicknames to what ever format
4030 they prefer. Affected file lib/silcclient/silcapi.h.
4032 Added function silc_client_nickname_format to the file
4033 lib/silcclient/idlist.c. It performs the nickname formatting.
4035 Added new field `hostname´ to the SilcClientEntry context.
4036 It holds the hostname of the client. Affected file is
4037 lib/silcclient/idlist.h.
4039 * Irssi SILC Client sets the nicknames in nick@hostn format.
4040 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4041 irssi/src/silc/core/silc-core.c.
4043 The WHOIS printing now also shows both the real nickname and
4044 the formatted nickname so that user knows how to access the
4045 user if there are multiple same nicknames cached. Affected
4046 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4047 printing formatting too to take the hostname now as a separate
4048 argument. The Affected file is
4049 irssi/src/fe-common/silc/modules-formats.[ch].
4051 * Changed the silc_client_get_clients_local to accept the formatted
4052 nickname as argument. It accepts the real nickname too but the
4053 formatted nickname can be used to find the true entry from
4054 multiple entries. Affected file lib/silcclient/silcapi.h and
4055 lib/silcclient/idlist.c.
4057 * Added nickname_format_parse field to the SilcClientParams.
4058 It is a callback function provided by the application to parse
4059 the nickname out of the formatted nickname string. The library
4060 calls it to get the nickname from the formatted string. Since
4061 the application generally knows better the format of the nickname
4062 string it parses it instead of the library, even though library
4063 encodes the formatted string. If the callback function is not
4064 provided then the library will use the string as is. The
4065 affected file is lib/silcclient/silcapi.h.
4067 * All the nickname strings passed to the client library in
4068 commands are now expected to be formatted nickname strings.
4069 If the command does not support the formatted nickname string
4070 it will assume that the sent string is the actual nickname.
4071 Affected file lib/silcclient/command.c.
4073 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4075 * Added public key authentication support to OPER and SILCOPER
4076 commands in the client library. Affected file is
4077 lib/silcclient/command.c.
4079 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4081 * Changed the get_auth_methdod client operation to be asynchronous.
4082 It can be async if the application resolves the authentication
4083 method from the server during the negotiation. Added new
4084 SilcGetAuthMeth completion callback that the application will
4085 call after resolving the authentication method.
4087 Added function silc_client_request_authentication_method that
4088 the application can use to resolve the authentication method
4089 from the server. Added also SilcConnectionAuthRequest callback
4090 that the library will call after the server has replied. The
4091 application can call this function if it does not know the
4092 current authentication method.
4094 Affected files are lib/silcclient/client.c and
4095 lib/silcclient/silcapi.h.
4097 * The Irssi SILC client now automatically resolves the authentication
4098 method incase any configuration information is not present (and
4099 currently there never is). The affected file is
4100 irssi/src/silc/core/client_ops.c.
4102 * Fixed public key authentication from the client library.
4103 Affected file lib/silcclient/protocol.c. Changed also the
4104 protocol specification about the public key authentication in
4105 the connection authentication protocol. The actual data to be
4106 signed is now computed with a hash function before signing.
4108 * Fixed the public key authentication from the server as well.
4109 Affected file silcd/protocol.c.
4111 * Removed the mlock()'s from the memory allocation routines.
4112 Affected file lib/silcutil/silcmemory.c. The ./configure does
4113 not check anymore for the mlock(). Affected file is
4116 * Fixed USERS command in server to allow the execution of the
4117 command for private and secret channels if the client sending
4118 the command is on the channel. Affected file silcd/command.c.
4120 * Fixed silc_client_get_clients_local to return the clients
4121 count correctly. It could return wrong value. Affected file
4122 lib/silcclient/idlist.c.
4124 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4126 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4127 types. The assembler optimizations seemed not to like 64-bit
4128 data types. The assmebler optimizations thus are now enabled
4129 also for BSD systems as opposed to only enable them for Linux.
4131 * Do not check for threads at all on BSD systems. Affected
4132 file configure.in.pre.
4134 * Removed -n and -h options from the Irssi SILC Client since
4135 they are not used in silc.
4137 * Fixed the prime generation to assure that the first digit
4138 of the generated random number is not zero since our conversion
4139 routines does not like number strings that starts with zero
4140 digit. If zero digit is seen the random number is regenerated.
4141 This caused some corrupted RSA keys when the zero first digit
4142 was met. Affected file lib/silcmath/silcprimegen.c.
4144 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4146 * Fixed WIN32 configuration in the ./configure script.
4147 Fixed to include xti.h on environments that has it.
4148 Patches by Carsten Ilchmann and andrew.
4150 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4152 * Changed the silc_id_create_client_id to be collision
4153 resistant. It is now assured that there cannot be created
4154 two same client ID's. I suspect that some weird bugs in
4155 the server were actually caused by duplicate Client IDs.
4156 Affected file silcd/serverid.[ch]. A router receiving
4157 new ID now also assures and informs the sending server
4158 if the ID caused collision.
4160 * Changed the silc_id_create_channel_id to also assure that
4161 there are no collisions.
4163 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4165 * Statement about ignoring the Mutual Authentication flag when
4166 performing rekey with PFS was a bit misleading. It is ignored
4167 if it was set in the initial negotiation, it cannot be even
4168 set in the rekey. Fixed in the ke-auth draft. Started the
4169 new versions of the protocol drafts in the doc/.
4171 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4173 * Fixed a bug in silc_client_command_identify_save when saving
4174 new channel information. The channel name was no duplicated
4175 and caused crash on exit. Affected file is
4176 lib/silcclient/command_reply.c.
4178 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4180 * Fixed the getkey command handling in the server. Send just
4181 empty OK reply to the sender if the key could not be fetched
4182 (but everything else was ok, like the key just was not available).
4183 Changed the public key parameter to optional in the protocol
4184 specs so that empty OK reply can be sent. Affected file
4187 Added a message to Irssi SILC client to tell to user if the
4188 server did not return a public key.
4190 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4192 * Fixed a channel key regeneration bug. It registered new
4193 timeout tasks exponentially until all system resources were
4194 used. Affected file silcd/server.c.
4196 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4198 * Added the SILC Document generator to the scripts/silcdoc.
4199 It can be used to generate the Toolkit Reference Manual out
4200 of the source tree. Internally it will also use the RoboDoc
4201 generator now imported in util/robodoc.
4203 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Added couple of return's in rekey protocol if error orccurred
4206 during the protocol. The execution must be terminated.
4207 Affected file silcd/protocol.c. Also, terminate the protocol
4208 always with timeout.
4210 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4212 * The client's Client ID was created initally from the wrong
4213 nickname (it could have been in format nick@host) in the
4214 silc_server_new_client. Affected file silcd/packet_receive.c
4216 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4218 * Added some SILC_LOG_ERROR's to various error conditions
4219 if client could not be added to ID cache. Affected files
4220 silcd/packet_receive.c and silcd/server.c.
4222 * When client's sock->user_data is freed, NULL also the
4223 client->router and client->connection pointers. Added check
4224 for these pointers being NULL to various places around the
4225 code. Affected file silcd/server.c.
4227 * Added client->data.registered == TRUE checks to various
4228 places around the code to assure that unregistered client's
4229 are not handled when it is not allowed. Affected file
4232 * Added `bool registered' fields to all
4233 silc_idlist_[server|client]_get_* routines to indicate whether
4234 the fetched client needs to be registered or not. Affected
4235 file silcd/idlist.[ch].
4237 * Add your own entry as registered to the ID cache in the
4238 server. Affected file server.c.
4240 * Fixed a bug in silc_server_new_server. The SilcServer was
4241 set as the new server's context instead of SilcServerEntry.
4242 This naturally caused some weird bugs.
4244 * Added "updated" field the SilcChannelEntry which indicates
4245 the time since the channel entry was last accessed. This
4246 can be used to determine whether it is necessary to
4247 announce the channel after backup resuming protocol.
4248 Affected files silcd/idlist.[ch].
4250 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4252 * Do not delete the channel rekey task when adding it
4253 for in silc_server_create_channel_key.
4255 * Changed the silc_server_create_channel_key to return
4256 TRUE or FALSE to indicate the success of the channel key
4259 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4261 * Fixed MSVC++ project files and added missing files to

4264 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4266 * Do not add TCP_NODELAY flag if the operating system
4267 does not have it defined. Affected files are
4268 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4270 * Fixed buffer overflow from Irssi SILC Client. Affected
4271 file irssi/src/fe-common/core/themes.c.
4273 * Fixed double free in client library in the file
4274 lib/silcclient/client.c when disconnecting from server.
4276 * Applied double free patch from cras to Irssi SILC client.
4277 Affected files irssi/src/core/[modules/expandos].c
4279 * Fixed the disconnection handling to Irssi SILC Client.
4280 The application must call silc_client_close_connection
4281 in ops->connect client operation in case of failure of
4282 the connection. Affected file is
4283 irssi/src/silc/core/client_ops.c.
4285 * Do not set sock->protocol to NULL in the function
4286 silc_client_close_connection after executing the protocol's
4287 final callback since the sock might not be valid anymore.
4288 Affected file lib/silcclient/client.c.
4290 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4292 * Do not enable SILC_THREADS if the linking with libpthread
4293 did not happen. Affected file configure.in.pre.
4295 * Added notion to protocol specification that server must
4296 verify the sent authentication payload with CMODE when
4297 setting the channel founder key. Implemented it to the
4298 server. Affected file silcd/command.c.
4300 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4302 * Added _EXTRA_DIST SILC distribution variable to the
4303 distributions file. It is used to conditionally add extra
4304 files or directories to the specific distribution. Affected
4305 files ./prepare, Makefile.am.pre and distributions.
4307 Removed the `_' from the start of the distribution names.
4310 * Added README.WIN32 for instructions to compile the Toolkit
4313 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4315 * Fixed a double free in disconnection in the server. Affected
4316 file is silcd/server.c.
4318 * Fixed the lib/silcske/groups.c to work now also with GMP
4319 MP library. The string conversion did not work when using
4320 specific base and the base is indicated in the string as well.
4322 * Created win32/ directory which now includes MSVC++ specific
4323 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4324 It will appear only in the toolkit distribution
4326 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4328 * Changed the key material distribution function in case when
4329 the hash output is too short. The data is now concatenated
4330 a bit differently than it used to. Made the change to the
4331 SKE protocol specification.
4333 * Added better GMP detection to configure.in.pre. A patch
4336 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4338 * Fixed a minor bug in SKE that might cause some problem on
4339 some platforms. Affected file lib/silcske/silcske.c.
4341 * Added the cookie checking for initiator in the SKE. It checks
4342 that the responder returns the sent cookie unmodified. The
4343 affected file is lib/silcske/silcske.c. Added new SKE
4344 error type INVALID_COOKIE that can be sent during the
4345 negotiation. Fixed some memory leaks as well.
4347 * Added the "invalid cookie" error message to Irssi SILC client's
4350 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4352 * Added `task_max' field to the SilcClientParams to indicate
4353 the maximum tasks the scheduler can handle. If set to zero,
4354 default values are used. Affected file lib/silcclient/silcapi.h.
4356 * Fixed memory leaks in silc_client_close_connection. Affected
4357 file lib/silcclient/client.c.
4359 * Added silc_client_del_client_entry to client library to free
4360 all memory of given client entry. Affected file is
4361 lib/silcclient/idlist.[ch].
4363 * Added new functions silc_client_del_channel and
4364 silc_client_del_server to delete channel and server entries.
4365 Affected file lib/silcclient/[silcapi.h/idlist.c].
4367 * Removed silc_client_del_client_by_id from silcapi.h.
4369 * Fixed the INFO command to return the server's own info
4370 correctly when querying by Server ID. Affected file is
4373 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4375 * Removed the non-blocking settings in WIN32 code in the
4376 silc_sock_[read/write] and added SleepEx instead. Affected
4377 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4378 of input data is now checked with FIONREAD and ioctlsocket.
4380 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4382 * Call silc_schedule_task_del_by_context in the
4383 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4384 Affected file lib/silccore/silcprotocol.c.
4386 * Call silc_protocol_cancel for active protocols in the
4387 silc_server_close_connection if the funtion
4388 silc_server_free_sock_user_data has not been called.
4389 Affected file silcd/server.c.
4391 * Generic tasks cannot be deleted using the del_by_fd
4392 task deleting function since generic tasks does not match
4393 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4395 * Added a notion to SILCOPER help file that the SILCOPER works
4396 only on router server, not on normal server.
4398 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4400 * Added for WIN32 support for the new scheduler as well.
4401 Affected file lib/silcutil/win32/silcwin32schedule.c.
4403 * Fixed the SHA1 implementation to work on various platforms.
4405 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4407 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4408 API. It is part of the scheduler now. Everything else is
4409 as previously but some functions has changed their names.
4410 Checkout the lib/silcutil/silcschedule.h for the interface.
4411 Updated all applications to use the new interface. Affected
4412 files are lib/silcutil/silcschedule.[ch].
4414 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4416 * Found a bug in the SKE implementation. The HASH value,
4417 specified by the protocol, was not computed correctly. The
4418 public key of the responder was not added to the computation
4419 even though it is mandatory. Affected file lib/silcske/silcske.c.
4420 This unfortunately causes incompatibilities with older
4421 clients and servers.
4423 * Added WIN32 specific network init and uninit functions:
4424 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4425 the Winsock2. Affected file lib/silcutil/silcnet.h and
4426 lib/silcutil/win32/silcwin32net.c.
4428 * Set the socket always to nonblocking mode on WIN32 after
4429 reading data or writing data. Affected file is
4430 lib/silcutil/win32/silcwin32sockconn.c.
4432 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4434 * Fixed various compilation problems under WIN32. Affected
4435 files lib/silcutil/win32/silcwin32thread.c and
4436 lib/silcutil/win32/silcwin32schedule.c.
4438 * Removed all _internal.h #includes from public header
4439 files. Internal headers must never be included from
4442 Removed also the lib/silcske/payload_internal.h file.
4444 * All include files that may be needed (public and some others
4445 included by the public headers) by application developers are
4446 now copied to the ./includes directory. It does not copy any
4447 internal headers. Affected file Makefile.defines.pre and all
4448 Makefile.am's under lib/ and subdirs.
4450 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4452 * Do not change the ~/.silc directory's permissions automatically.
4453 Affected file irssi/src/silc/core/clientutil.c.
4455 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4457 * Do not cancel the protocol in silc_server_close_connection
4458 it might cause recursion. Now cancelled in the function
4459 silc_server_free_sock_user_data. Affected file silcd/server.c.
4461 * Fixed the silc_server_remove_clients_by_server to regenerate
4462 the channel keys correctly finally. Added also new function
4463 silc_server_remove_clients_channels to actually do it.
4464 Affected file silcd/server.c.
4466 * Fixed the silc_server_new_channel to not crash by giving
4467 wrong router to the new channel. Affected file is
4468 silcd/packet_receive.c.
4470 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4472 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4473 which is given as argument to the silc_client_alloc now.
4474 It can be used to configure the client and set various parameters
4475 that affect the function of the client.
4477 * The USERS command in server did not check whether the channel
4478 is private or secret. Affected file silcd/command.c.
4480 * Added new argument to the USERS command in protocol specification.
4481 The USERS command now can take the channel name as argument
4482 as well. Added support for this in client and server and
4483 updated the protocol specs.
4485 * Completed the GETKEY command in client. It can be now used
4486 to fetch also servers public key not only some clients.
4487 Affected files lib/silcclient/command[_reply].c.
4489 * Added silc_client_get_server to return server entry by the
4490 server name. Affected files lib/silcclient/silcapi.h and
4493 * Redefined the IDENTIFY command in protocol specification to be
4494 more generic. It now can be used to query information about
4495 any entity in the SILC Network, including clients, servers and
4496 channels. The query may be based either the entity's name
4497 or the ID. Added support for this in both client and server.
4499 Affected files silcd/command.c and lib/silcclient/command.c
4500 and command_reply.c.
4502 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4503 the _from_client and _from_server functions. Affected file
4506 * Added silc_client_get_channel_by_id_resolve to the file
4507 lib/silcclient/silcapi.h to resolve channel information by
4508 its ID. Added also silc_client_get_channel_by_id that
4509 does not resolve it from the server.
4511 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4513 * Added SilcServerEntry context into the client library
4514 to represent one server. The INFO command now allocates
4515 these to save the resolved server info. For now on the
4516 client library will also keep information about servers,
4517 connected and resolved with INFO.
4519 The INFO command now allocates the SilcServerEntry context
4520 and saves the server info there. The COMMAND_REPLY in
4521 the INFO now returns the parameters to application in
4522 same order as defined in the protocol specification.
4524 The entries are cached in the client->server_cache.
4526 * The INFO command is now issued after received the Client ID
4527 from the server. Affected file lib/silcclient/client.c.
4529 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4530 to the application as the mode changer might be server.
4531 It is guaranteed that NULL is not returned anymore to the
4532 application. Affected file lib/silcclient/client_notify.c.
4534 The ID Type is now also passed to the application so that
4535 it can check whether the returned entry is SilcClientEntry
4538 Added new function silc_client_get_server_by_id to return
4539 the server entry by ID. Affected files are the
4540 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4542 * Do not create the channel in the Irssi SILC Client when issuing
4543 the JOIN command but when received the sucessful JOIN command
4544 reply. Otherwise the channel might get created even though we
4545 could not join it. The Affected file is
4546 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4548 * Fixed a channel joining bug in router. The router must also
4549 check the channel modes, invite and ban lists etc. when serving
4550 the JOIN command sent by normal server. Affected file is
4551 silcd/command.c. The router now resolves the client's
4552 information from the server who sent the JOIN command if it
4553 does not know it, and processes the JOIN command only after
4556 * Changed the SilcCommandCb to take new argument; void *context2.
4557 Affected file lib/silccore/silccommand.h
4559 The second argument in the command callbacks in the server now
4560 includes the SilcServerCommandReplyContext if the command was
4561 called as pending command callback from the command reply.
4562 Otherwise it is NULL. When called as pending the status of the
4563 command reply will be checked and if it was erronous the
4564 error will be sent to the original sender of the command.
4565 This way the client always receives the error messages even
4566 though the server was actually the one who received the error
4567 when it resent the command to router, for example. Affected
4568 files silcd/command[_reply].[ch].
4570 * Fixed sending WHOWAS command's error message to client if
4571 the requested client could not be found. It was missing.
4574 * Changed the CMODE and CUMODE commands reply arguments in the
4575 protocol specification. The Channel ID is now sent in both
4576 of the commands to identify the channel. Implemented this
4577 new feature to the client and server. Affected files
4578 lib/silcclient/command_reply.c and silcd/command.c.
4580 * Made better checks for invite and ban lists in the JOIN
4581 command in server. Affected file silcd/command.c.
4583 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4585 * The server now performs the incoming host IP/DNS lookup
4586 using the silc_socket_host_lookup and thus does not block
4587 the server anymore. Affected file silcd/server.c.
4589 * Completed the multi-thread support for SILC Scheduler in
4590 the lib/silcutil/silcschedule.c.
4592 * Fixed the configure.in.pre to detect the pthread correctly
4595 * Fixed a deadlock in silc_task_queue_wakeup in the file
4596 lib/silcutil/silctask.c.
4598 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4600 * Added new function silc_schedule_wakeup that is used in
4601 multi-threaded environment to wakeup the main thread's
4602 schduler. It needs to be used when a thread adds a new task
4603 or removes a task from task queues. After waking up, the
4604 scheduler will detect the task queue changes. If threads
4605 support is not compiled in this function has no effect.
4606 Implemented the wakeup mechanism to both Unix and WIN32
4607 systems. Affected files are lib/silcutil/silcschedule.[ch],
4608 lib/silcutil/unix/silcunixschedule.c and the
4609 lib/silcutil/win32/silcwin32schedule.c.
4611 * Added new function silc_task_queue_wakeup to wakeup the
4612 scheduler by the specified task queue. Affected file
4613 lib/silcutil/silctask.[ch].
4615 * The silc_socket_host_lookup_start now wakes up the scheduler
4616 after adding the timeout task. Affected file is
4617 lib/silcutil/silcsockconn.c.
4619 * The silc_socket_host_lookup is synchronous now if the threads
4620 support is not compiled in. However, the callback is still
4621 called asyncronously through the scheduler, anyway. Affected
4622 file lib/silcutil/silcsockconn.c.
4624 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4626 * Added new function silc_socket_host_lookup to perform
4627 asynchronous IP and FQDN lookups for the socket connection.
4628 Affected files lib/silcutil/silcsockconn.[ch].
4630 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4632 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4633 that may or may not compile the mutex support in.
4635 Changed the silc_mutex_alloc interface. It allocates the
4636 mutex now to the sent pointer and returns TRUE or FALSE.
4638 Affected file lib/silcutil/silcmutex.h.
4640 * Wrote the SILC Task Queue interface to support multi-threads.
4641 Affected file lib/silcutil/silctask.[ch].
4643 * Wrote the SILC Scheduler to support multi-threads. Affected
4644 file lib/silcutil/silcschedule.c.
4646 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4648 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4649 in lib/silcutil/win32/.
4651 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4653 * Defined SILC Mutex API and SILC Thread API and implemented
4654 them for Unix. Affected files are
4655 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4656 lib/silcutil/unix/silcunixmutex.c and
4657 lib/silcutil/unix/silcunixthread.c.
4659 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4661 * Fixed the silc_server_remove_clients_by_server's channel
4662 key re-generation. The hash table handling was incorrect
4663 and would not work with many channels. Affected file is
4666 * Fixed some memory leaks around the server code.
4668 * Rewrote the silc_server_get_users_on_channel to support IPv6
4669 based Client ID's. Affected file silcd/server.c.
4671 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4672 specification. However, a separate document must be written
4673 to define the detailed signing procedure and the payload
4674 associated with the flag. Defined the flag to the
4675 lib/silccore/silcchannel.h as well.
4677 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4679 * Changed the dynamic tables to static size tables in the
4680 lib/silccrypt/silchmac.c.
4682 * Removed GCC dependencies from the code. A patch by cras.
4684 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4686 * Do not show the error "Error receiving packet bla bla"
4687 in server if it really was not an error (-2 means that reading
4688 is pending). Affected file silcd/server.c.
4690 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4692 * Fixed a possible crash in silc_server_remove_clients_by_server
4693 in silcd/server.c. Fixed there also some memory leaks.
4695 * Fixed the silc_idlist_replace_client_id. It could replace
4696 wrong key in the hash table. Affected file silcd/idlist.c.
4698 * Do not check whether there are global users on the channel
4699 if the channel->global_users is FALSE. Affected functions
4700 silc_server_remove_from_one_channel and
4701 silc_server_remove_from_channels in silcd/server.c. Also,
4702 do not check if the removed client is local as we can be
4703 sure that global client was not removed from the channel
4704 and checking for global users is not needed.
4706 * The silc_server_remove_clients_by_server now re-generates
4707 the channel keys correctly for those channels that had
4708 clients removed from them. Affected file silcd/server.c.
4710 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4712 * Found the reason of random crashes in the server. We weren't
4713 ignoring the SIGPIPE signal (which can be sent in write())
4714 and it crashed the server. Affected file silcd/silcd.c.
4716 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4718 * Assure that sock->user_data is not NULL in the function
4719 silc_server_packet_send in silcd/packet_send.c.
4721 * Disconnect the remote connection if it could not be added
4722 to any ID lists in the server. The affected file is
4725 * Check in silc_server_packet_send[_real/dest] that the
4726 socket is not disconnecting and ignore the data if it is.
4727 Affected file silcd/packet_send.c.
4729 * Define inline to __inline on native WIN32 compilation.
4730 Affected file includes/silcwin32.h.
4732 * Added some explicit type casts for inline code since MSVC
4733 require them. Affected files lib/silcutil/silcbuffer.h,
4734 lib/trq/silcdlist.h and lib/trq/silclist.h.
4736 * Print warning in log files from now on if the packet
4737 decryption fails. Affected file silcd/server.c.
4739 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4741 * Changed the `say' client operation's interface to accept
4742 new `type' argument to indicate the type of the message sent
4743 by the library. The application may filter the library's
4744 messages according the type. The affected file is the
4745 lib/silcclient/silcapi.h.
4747 * Added two new functions to lib/silcclient/silcapi.h:
4748 silc_client_del_client and silc_client_del_client_by_id.
4749 Affected file lib/silcclient/idlist.c.
4751 * Moved the clientincludes.h from includes/ to silc/ and
4752 serverincludes.h from includes/ to silcd/.
4754 * The modes for the CMODE and CUMODE are now passed as
4755 uint32 for application with COMMAND_REPLY. The affected
4756 file is lib/silcclient/command_reply.c.
4758 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4760 * /WHOIS without arguments shows client's own information.
4761 Affected file lib/silcclient/command.c.
4763 * Changed PING to not accept any arguments. The specs
4764 says that client can ping only the connected server so
4765 requiring an argument is not needed. Affected file is
4766 lib/silcclient/command.c.
4768 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4770 * Fixed a fatal bug in private message sending and reception
4771 encryption and decryption when using private message keys.
4772 The implementation was incorrect and did not follow the
4773 specification. It causd that some of the message were
4774 lost since it did not use the sending and receiving keys
4775 as the protocol suggests. This has been fixed and will cause
4776 incompatibilities with older clients when sending private
4777 message encrypted with private message keys. Affected files
4778 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4779 and various other in Irssi SILC Client.
4781 Added `responder' boolean argument to the functions
4782 silc_client_add_private_message_key[_ske] to indicate when
4783 the key is added as responder or initiator of the key
4786 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4788 * Removed the silc_ske_check_version function and created
4789 a SilcSKECheckVersion callback. Added also a function
4790 silc_ske_set_callbacks that is now used to set all SKE
4791 callbacks. The callback functions are not given to
4792 the SKE functions anymore, but this function is used to
4795 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4797 * Added `silc_version' argument to the silc_client_alloc
4798 to define the version of the application for the library.
4799 The library will use the version string to compare it
4800 against the remote host's (usually a server) version
4801 string. Affected file lib/silcclient/silcapi.h
4803 * Added the KE protocol context to Key Agreement context
4804 in client library so that we can abort the SKE if it
4805 is in process when we get timeout. Affected file is
4806 lib/silcclient/client_keyagr.c.
4808 * Do not resolve the client ID forever if it returns in the
4809 first time that such client does not exist. This was done
4810 for example with private message. Affected file is
4811 lib/silcclient/client_prvmsg.c.
4813 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4815 * Do not add regex.h for WIN32. The affected file
4816 includes/silcincludes.h.
4818 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4819 not work yet 100%. It generates the DLL's automatically
4820 when compiling with --with-win32 under cygwin.
4822 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4824 * lib/contrib/regex.c is not compiled on WIN32.
4826 * Added silc_net_get_socket_opt function to the
4827 lib/silcutil/silcnet.h.
4829 * Added includes/silcwin32.h for WIN32 specific includes
4832 * Do not use ptime structure or any of the posix process
4833 functions on WIN32 in lib/silccrypt/silrng.c.
4835 * Added silc_gettimeofday to provide generic function
4836 for struct timeval on all platforms. Added the function
4837 to lib/silcutil/silcutil.h.
4839 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4841 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4842 library as they clearly belong there. As a plus side we
4843 can make the actual socket connection routines platform
4846 Added also new generic function silc_socket_read and
4847 silc_socket_write (that used to be silc_packet_[read/write].
4848 The implementation of these are platform specific.
4850 * Added WIN32 specific routines of silc_socket_[read/write]
4851 to lib/silcutil/win32/silcwin32sockconn.c.
4853 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4855 * Added preliminary support for native WIN32 compilation under
4856 cygwin (using the -mno-cygwin option for GCC) to the
4857 ./configure.in.pre. The --with-win32 now prepares the
4858 compilation for native WIN32.
4860 * Rewrote the SILC Scheduler interface in the file
4861 lib/silcutil/silcschedule.h. The scheduler is now context
4862 based and does not have anymore any global static scheduler.
4863 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4864 and created lib/silcutil/win32 directory for WIN32 based
4867 * Added Unix specific network routines to the
4868 lib/silcutil/unix/silcunixnet.c and the old
4869 lib/silcutil/silcnet.c includes now only generic routines.
4871 Added WIN32 specific network routines to the
4872 lib/silcutil/win32/silcwin32net.c.
4874 * Added Unix specific utility functions from the
4875 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4877 * Added WIN32 SILC Scheduler to the file
4878 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4881 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4883 * Do not handle JOIN notify in the server if the target client
4884 is not registered (idata->registered == FALSE). The affected
4885 file is silcd/packet_receive.c.
4887 * Update the nickrec->founder in event_cumode in the Irssi SILC
4888 client. Affected file irssi/src/silc/core/silc-channels.c.
4890 * Fixed the CUMODE_CHANGE notify handling in the server when
4891 server and router are announcing their clients on channels.
4892 Now the mode changes are saved and notified correctly. The
4893 affected file is /silcd/packet_receive.c.
4895 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4896 They really did not replace the cache entry in the ID Cache.
4897 Now they do that. Affected file silcd/idlist.c.
4899 * Fixed the KICK notify handling in the Irssi SILC client to
4900 update the channel records so that the kicked client does not
4901 appear to be on the channel. The affected file is
4902 irssi/src/silc/core/silc-channels.c.
4904 * Always update the conn->current_channel when executing command
4905 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4907 * Fixed the KILL notify handling in Irssi SILC client to remove
4908 the killed client on all channels.
4910 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * Fixed the silc_parse_command_line to remove extra spaces
4913 from the start and end of the arguments. Affected file is
4914 lib/silcutil/silcutil.c.
4916 * Cancel and free any active protocol in the function
4917 silc_server_close_connection. Affected file silcd/server.c.
4919 * Cancel and free any active protocol in the function
4920 silc_client_close_connction. Affected file is
4921 lib/silcclient/client.c.
4923 * Do not execute the KILL command for clients that are in
4924 history (ie. they are not in the network). Affected file is
4927 * Fixed KILL notify handling, client does not crash anymore.
4928 Affected file irssi/src/silc/core/silc-channels.c.
4930 * Reduced the default packet buffer size from 2048 to 1024 in
4931 lib/silccore/silcpacket.c.
4933 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4934 counter to the SKE context that is incresed when the SKE library
4935 performs async operation outside the library. If the outside
4936 process frees the SKE context and FREED status will be set
4937 and the library will detect after the sync operation that the
4938 libary is freed. The affected files are
4939 lib/silcske/silcske[_status].[ch].
4941 * Resolve the client entry information in the function
4942 silc_client_channel_message to assure that NULL pointer is not
4943 passed as client entry to the application. */
4945 * Fixed the task timeout calculation to assure that there is
4946 never negative timeouts. The affected file is
4947 lib/silcutil/silcschedule.c.
4949 * Fixed the channel user mode notification sending in server.
4950 It was sent point-to-point to the router (or to server by router)
4951 but it needs to be destined to a channel. The routines now
4952 supports sending the channel user mode notifys to the channels
4953 when announcing clients and channels. Affected files are
4954 silcd/server.c and silcd/packet_receive.c.
4956 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4957 It did not actually replace the old channel entry in the cache.
4958 Affected file lib/silcclient/client_notify.c.
4960 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Fixed a possible crash in silc_packet_send_prepare. It now
4963 assures always that there is enough space in the buffer and
4964 at the tail area of the buffer (for MAC).
4966 Fixed the inbound buffer reallocation in silc_packet_read.
4967 It was old code and did not handle the reallocation correctly.
4970 The affected file is lib/silccore/silcpacket.c.
4972 * Fixed buffer overflow in silc_parse_nickname in the file
4973 lib/silcutil/silcutil.c.
4975 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * make install generates new server keys only if there is not
4980 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4983 Added check that if the NOREPLY is set then we will not send
4984 the away message. This avoids infinite loop of away messages
4985 if both clients are away. The affected file is
4986 lib/silcclient/client_prvmsg.c.
4988 * Fixed client crash if /NICK was given without arguments.
4989 Affected file lib/silcclient/command.c.
4991 * Server does not send the invite list in INVITE command back
4992 to the client if the list was not altered. Added this notion
4993 to the protocol spec as well. Affected file silcd/command.c.
4995 Fixed possible crash in INVITE command by checking the
4996 value of silc_server_get_client_route command.
4998 * Fixed the INVITE notify type handling. The arguments are now
4999 taken in correct order and client does not crash. The affected
5000 file is irssi/src/silc/core/silc-channels.c.
5002 Removed the "Inviting xxx to channel" message from the
5003 client library away and let the application handle it.
5004 Affected file lib/silcclient/command.c. Added that message
5005 to Irssi SILC client's message formats.
5007 * Fixed CMODE command crash in client. It now checks the
5008 amount of arguments correctly and does not crash. The affected
5009 file is lib/silcclient/command.c.
5011 * Do not create new channel automatically in silc_channels_join
5012 but check whether the channel by that name already exists.
5013 Affected file irssi/silc/core/silc-channels.c.
5015 * Do not send the SERVER_SIGNOFF to router if the disconnected
5016 entity was the router. Affected file silcd/server.c.
5018 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5019 SILC client as it was missing from there.
5021 Added the handling of the KICK notify to the Irssi SILC client
5022 as it was missing. Added "you have been kicked" message to
5023 Irssi SILC client's message modules formats.
5025 Added the handing of the KILL notify to the Irssi SILC client
5026 as it was missing. Added the kill message module formats
5029 The affected file is irssi/src/silc/core/silc-channels.c.
5031 * The router did not save the channel mode the server announced.
5032 Affected file silcd/packet_receive.c.
5034 * Fixed a possible crash in INFO command in server. If the
5035 server did not provide the server info it crashed. Affected
5036 file silcd/command.c.
5038 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Fixed the GETKEY command in the server to check also the
5041 global list. Otherwise the GETKEY would not work correctly
5042 in normal SILC server. Affected file silcd/command.c.
5044 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Fixed GETKEY crash, it crashed if the command did not succseed.
5048 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5051 is now real and not just an macro interface to GMP.
5053 Removed the entire GMP from the source tree and imported new
5054 NSS MPI library instead. Reason for removing GMP is that it is
5055 extremely large and compiles extremely slow. The NSS MPI
5056 is only a few files and compiles in less than 10 seconds.
5057 The speed is also about the same as GMP. The MPI is imported
5058 to lib/silcmath/mpi.
5060 If the system has GMP installed we will still use the GMP.
5061 If it is not then the NSS MPI will be compiled.
5063 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Merged a long nickname (127 characters long) crash bugfix from
5066 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5068 * Merged a freed memory reference bugfix from Irssi CVS tree.
5069 Affected file irssi/src/core/commands.c.
5071 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Added the server's public key sving and verification to the
5074 server when performing the SKE. This was missing and the
5075 remote server's (or router's) public key was accepted without
5076 checking whether we have it previously or trust it at all.
5077 Affected file silcd/protocol.c.
5079 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Check in the silc_server_timeout_remote if protocol is active
5082 and make sure that the protocol's final callback is called so
5083 that all memory if freed. Affected file silcd/server.c.
5085 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * silc_server_whois_send_reply crashed the server if the nickname
5088 was 127 characters long. Affected file silcd/command.c.
5090 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Added sanity check to the silc_server_new_client. If the hostname
5093 is provided inside username then check that the provided hostname
5094 really is the same as the resolved one. If the hostname was not
5095 resolved then check it from the public key. Affected file is
5096 silcd/packet_receive.c.
5098 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5099 if the server disconnected us and the connection is not valid
5100 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5102 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5103 the library to the lib/silcutil/silcutil.[ch].
5105 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Close log file after open. Affected file
5108 lib/silcutil/silclog.c.
5110 * Check whether sock == NULL in silc_client_send_packet and return
5111 if it is. Affected file lib/silcclient/silcclient.c.
5113 * Check rec->entry == NULL in the Irssi SILC Client before
5114 sending the channel message. Affecte file is
5115 irssi/src/silc/core/silc-servers.c.
5117 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Merged a splitted window bugfix from Irssi CVS tree. The
5120 affected file is irssi/src/fe-text/textbuffer-view.c.
5122 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5123 It did not print nickname.
5125 * Improved the distributions system a bit.
5127 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5130 irssi/src/fe-text/gui-window.c.
5132 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5133 to in-active server. The affected file is
5134 irssi/src/silc/core/client_ops.c.
5136 * Resolve the client in USERS command reply if the entry does
5137 not have username resolved. The affected file is
5138 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5139 command to WHOIS command to really resolve stuff. The USERS
5140 is not used any more in any critical section so WHOIS can
5141 be used even though it might be slower than IDENTIFY.
5143 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5146 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Changed the protocol API a bit more consistent in the
5149 lib/silccore/silcprotocol.[ch].
5151 * Changed the following headers to ROBODoc format:
5153 lib/silccore/silcpayload.h
5154 lib/silccore/silcprotocol.h
5155 lib/silccore/silcsockconn.h
5157 All core library headers are now formatted.
5159 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * Fixed a bug in Irssi SILC client; do not show that you are
5162 server/router operator if you really are not. Affected file is
5163 irssi/src/silc/core/client_ops.c.
5165 * Renamed silc_command_free_payload to silc_command_payload_free.
5166 Affected file lib/silccore/silccommand.h
5168 * Added silcmath.h to include the prototoypes of various routines
5169 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5172 * Changed the following headers to ROBODoc format:
5174 lib/silccore/silcchannel.h
5175 lib/silccore/silccommand.h
5176 lib/silccore/silcid.h
5177 lib/silccore/silcidcache.h
5178 lib/silccore/silcmode.h
5179 lib/silccore/silcnotify.h
5180 lib/silccore/silcpacket.h
5181 lib/silcmath/silcmath.h
5183 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Added checking to the server code not to start the server if
5186 ciphers and stuff are not configured properly. Affected files
5187 silcd/serverconfig.[h] and silcd/server.c.
5189 * Changed the layout of the header files of the public interfaces
5190 in the SILC libraries. The new layout supports ROBODoc
5191 documentation tool (and some others) so that it is easy to create
5192 a library reference manual. All the other headers and source
5193 code must still follow the CodingStyle document. Also source
5194 code must not include these ROBODoc stuffs, only the headers.
5195 Furthermore, all public interface headers must now be named
5196 by using `silc' prefix, example: silcapi.h, silccipher.h.
5197 Some files were renamed due to this. All the other headers
5198 must not be used as public interfaces. I will update the
5199 CodingStyle document later. Changed following headers, so far:
5201 lib/silcclient/silcapi.h
5202 lib/silccore/silcauth.h
5203 lib/silccore/silcprivate.h
5204 lib/silccrypt/silcdh.h
5206 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Removed silc_client_packet_send_flush from the client library
5211 as it is not needed. Affected file lib/silcclient/client.[ch].
5213 * Added printing of message of unresolved authentication method
5214 to the Irssi SILC client. Added it to the module formats.
5215 Removed the same message from the client library.
5217 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * Added new distribution feature, DISTLABEL. Every distribution
5220 can define own preprocessor label that can be used in the
5221 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5222 file distributions, acconfig.h.pre and prepare.
5224 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Added Makefile.defines_int to include the actual definitions
5227 for Makefile.defines.in. Tested the new distribution system,
5228 created distributions and tested installation.
5230 * Added AWAY message printing to the Irssi SILC client. Added
5231 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5233 * Added SCONNECT command to call the SILC's CONNECT command.
5234 Cannot use CONNECT directly since Irssi uses that internally.
5235 Affected file irssi/src/silc/core/silc-servers.c.
5237 Added ACTION local command. It is same as ME command but takes
5238 the channel as mandatory argument.
5240 Rewrote some of the Irssi's help files to suite for SILC
5243 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Added Makefile.defines[.in] that should for now on be included
5246 in all Makefile.am file in the source tree. That file includes
5247 all common compilation definitions for SILC source tree.
5249 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Minor changes to the ./prepare script to change the package
5252 name according the distribution name to the configure.in.
5254 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Created new distribution system. Added file `distributions'
5257 that defines all the distributions that can be created out of
5258 the SILC source tree. The ./prepare script now reads that
5259 file to determine how to prepare the distributions. The
5260 first argument to the ./prepare is the name of the distribution
5261 and second is the version of the distribution. If given
5262 without arguments it creates the default (toolkit) distribution
5263 with the default version (defined in ./prepare).
5265 All Makefile.am files that are subject to the distributions
5266 are now named as Makefile.am.pre. These are ./Makefile.am
5267 and lib/Makefile.am. Others may be changed later.
5269 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added invite list, ban list, some key management and connection
5272 error message printing to module formats in the Irssi SILC client.
5274 * Added new silc_client_set_away_message to set the away message
5275 that is back to the person who sent private message. The
5276 affected file lib/silcclient/silcapi.h and the
5277 lib/silcclient/client_prvmsg.c.
5279 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Fixed the private message sending in the Irssi SILC client,
5282 added local command KEY to the Irssi SILC client.
5284 Added key management and key agreement message formats to the
5285 irssi/src/fe-common/silc/module-formats.[ch].
5287 Added USERS (alias WHO) printing, server/router operator
5288 indication and LIST command printing to the module formats.
5290 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Fixed channel joining notify handling, cumode notify handling
5293 from Irssi SILC client.
5295 * Added SILC specific module-formats to the Irssi SILC client so
5296 that SILC specific message hilighting, colors etc is possible.
5297 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5299 Added channel mode, channel user mode, actions, notices,
5300 whois and whowas printing to the the module-formats.c.
5302 * Fixed a bug in channel deletion in the server. The channel
5303 is not left to the cache even if the channel founder auth mode
5304 is set when there are no users anymore on the channel. Affected
5305 file silcd/server.c.
5307 * The silc_net_localhost now resolves the entire hostname including
5308 the domain name. Affected file lib/silcutil/silcnet.c.
5310 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Changed the ask_passphrase client operation to be ascynchronous.
5313 It has now a completion callback and a context that the
5314 application must call after it has got the passphrase from
5315 the user. Affected files lib/silcclient/silcapi.h,
5316 lib/silcclient/protocol.c, lib/silcclient/command.c and
5319 Added SilcAskPassphrase callback that the application calls
5320 to deliver the passphrase to the library.
5322 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5323 The public key verification and especially a certificate
5324 verification is asynchronous procedure.
5326 Added new SILC_SKE_STATUS_PENDING status to indicate the
5327 request is pending and a callback will be called to finalize
5330 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5331 indicate that remote end did not send its public key (or
5332 certificate), even though we require it. Added check for this
5333 condition in the SKE. This was a security bug, now fixed.
5335 Defined new SilcSKEVerifyCbCompletion callback that is called
5336 when the verification process is completed.
5338 The affected files lib/silcske/silcske_status.h and
5339 lib/silcske/silcske.[ch].
5341 * Changed the verify_public_key client operation to be async
5342 as well. Defined SilcVerifyPublicKey callback that is used to
5343 indicate the success of the public key verification process.
5345 Changed the server and client to use the new async client
5348 * Changed the Irssi SILC client's internal scheduler to be called
5349 twice as many times as it used to be. As a result the client
5350 should be a bit faster now. Affected file is
5351 irssi/src/silc/core/silc-core.c.
5353 * Added support to Irssi SILC client of asynchronous public key
5354 verification and passphrase inquiry. Affected file is
5355 irssi/src/silc/core/silc-core.c.
5357 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Do not say "You have left channel %s" in client library.
5360 Moved it to the application. Affected files are
5361 lib/silcclient/command.c and silc/client_ops.c.
5363 * Fixed silc_client_get_clients. Command context was not
5364 duplicated and was freed memory in the callback. Affected
5365 file lib/silcclient/idlist.c.
5367 * Do not say "you are now talking..." on JOIN command in the
5368 client library. The appliation must handle it.
5370 * Do not say ".. changed topic to" in command reply in the
5371 client libary. The application must handle it.
5373 * Fixed TOPIC command sending in the client library.
5375 * Fixed a memory leak in silc_client_command_free in the file
5376 lib/silcclient/command.c.
5378 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Imported a modified version of Irssi client to the source tree.
5381 The Irssi will be used to create a new client called
5382 Irssi SILC. Imported to irssi/.
5384 Added silc_core_init_finish function to the Irssi. Affected
5385 file irssi/configure.in.
5387 A lot changes in the Makefile.ams around the irssi tree.
5389 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Do not rehash if the new size is same as the old size of the
5392 hash table, in the silc_hash_table_rehash*. The affected file
5393 lib/silcutil/silchashtable.c.
5395 * Replaced hash_table_del_by_context calls from the server
5396 (when channel->user_list and client->channels) to the
5397 hash_table_del as it is sufficient and faster.
5399 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Added silc_hash_table_list, silc_hash_table_get and the
5402 SilcHashTableList structure to provide an alternative way to
5403 traverse the hash table. The affected files are
5404 lib/silcutil/silchashtable.[ch].
5406 * Changed the server's idlist routines to use the hash table
5407 routines to optimize the code.
5409 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Replaced the client entry's `channel' list and channel entry's
5412 `user_list' list to hash tables for optimized lookup. Changed
5413 the code to use the hash table interface around the code.
5414 Affected file lib/silcd/idlist.[ch].
5416 * Added `auto_rehash' boolean argument to the function
5417 silc_hash_table_alloc to indicate whether the hash table should
5418 auto-rehash when it thinks is appropriate time. It will
5419 increase the hash table size if the there is twice as much
5420 entries in the table than the size of the table, and will
5421 decrease the size if there are twice as less entries than
5422 the size of the table.
5424 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5428 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * silc_idcache_purge_by_context deletes the entry now by context
5431 as it is supposed to do. Affected file lib/silccore/idcache.c.
5433 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5434 client is not anymore valid (WHOWAS givens the info) and not
5435 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5437 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Removed the `data' and `data_len' arguments from the ID Cache
5440 interfaces and added `name' argument. ID Cache does not handle
5441 anymore the binary data only a names associated with given ID.
5443 * When hashing a Client ID with silc_hash_id the entire ID is
5444 not hashed anymore, instead only the hash of the Client ID is
5445 hashed. This way we can access the Client ID from the cache
5446 with Client ID but with the hash of the ID (which is a hash of
5447 the nickname) as well without any difference in performance.
5449 Added also silc_idcache_find_by_id_one_ext to do one on one
5450 searching when we have the actual ID. Added also function
5451 silc_hash_client_id_compare. The affected files are
5452 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5454 * When hashing the name associated with a ID it is always done
5455 in lowercase. This way we can access the cache without worrying
5456 about case-sensitivity, even though, for example nicknames are
5459 * Fixed a bug in server with channel message sending. It put
5460 wrong ID type as destination ID. The affected file
5461 silcd/packet_send.c.
5463 * silc_idcache_del_by_context now deletes from all hash tables
5464 by context. Affected file lib/silccore/idcache.c.
5466 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Changed the client library to use the new ID Cache interface.
5469 Changes around the source tree.
5471 * Added silc_hash_table_rehash_ext to rehash with specific
5472 hash function. Affected file lib/silcutil/silchashtable.[ch].
5474 * Added silc_hash_string_compare to compare two strings in the
5475 hash table. Affected file lib/silcutil/silcutil.[ch].
5477 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Added new function silc_idcache_del_by_context into the
5480 lib/silccore/idcache.[ch].
5482 * Changed the server's ID list routines to use the new ID Cache
5483 interface. Changes around the source tree.
5485 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Added silc_hash_table_del[_by_context]_ext functions in to the
5488 lib/silcutil/silchashtable.[ch].
5490 Removed silc_hash_table_find_all* routines and added new
5491 silc_hash_table_find_foreach to replace them.
5493 Added silc_hash_table_replace_ext function as extended
5494 replacing function. Separated the simple hash table interface
5495 from the extended hash table interface in the file
5496 lib/silcutil/silchashtable.h.
5498 * Fixed minor bugs and changed it to use some of the new
5499 hash table functions in lib/silccore/idcache.c
5501 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Added new function silc_hash_table_find_all to return all keys
5504 in the hash table by the specified key. As the hash table is
5505 collision resistant it also makes it possible to have several
5506 duplicate keys in the hash table. This function may be used to
5507 find all of the keys from the hash.
5509 Added user_context arguments to the SilcHashFunction,
5510 SilcHashCompare and SilcHashDestructor to deliver user specified
5513 Added new fuctions silc_hash_table_find[_all]_ext to do
5514 extended lookup with specified hash and compare functions and
5515 specified user contexts.
5517 Added new function silc_hash_table_add_ext to add the key
5518 with specified hash function and user context.
5520 Added new function silc_hash_table_foreach to traverse all
5521 entrys in the hash table. Added SilcHashForeach callback
5524 Added new function silc_hash_table_del_by_context to delete
5525 the entry only if the context associated with the key matches.
5527 Affected files are lib/silcutil/silchashtable.[ch].
5529 * Removed silc_hash_[server/client/channel]_id and added just
5530 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5531 silc_hash_id_compare to compare two ID's using as the hash table
5532 comparison function. Added also silc_hash_data to hash
5533 binary data and silc_hash_data_compare to compare it.
5535 * Removed silc_idlist_find_client_by_hash as it is not needed
5536 anymore. Affected file silcd/idlist.[ch].
5538 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5539 to use internally the SilcHashTable. The new ID Cache is a lot
5540 faster than the old one. Some of the ID Cache interface was also
5541 rewritten and obsolete and stupid functions were removed.
5543 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Added entry_count field to the SilcHashTable to keep the number
5546 of the entries in the table. Implemented the function
5547 silc_hash_table_rehash. Added new function
5548 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5550 Fixed a minor bug in silc_hash_table_free.
5552 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5553 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5554 into the lib/silcutil/silcutil.[ch].
5556 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Implemented a collision resistant hash table into the
5559 lib/silcutil/silchashtable[ch]. See the header and the source
5560 for the SilcHashTable API.
5562 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Merged dotconf version 1.0.2 into lib/dotconf.
5566 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Do not compile anything in lib/silcsim/* if the SIM support
5569 is not enabled. The tree should now compile without problems
5572 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Compiled the SILC under cygwin. Compiled and tested briefly
5575 without problems. More tests needed. The SIMs didn't compile
5578 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5580 * Fixed possible crash in silc_get_username in the
5581 lib/silcutil/silcutil.c.
5583 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Fixed a va_arg in silc/client_ops.c.
5587 * Oops, RC5 routines were named AES and caused some problems
5588 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5590 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added new SilcIDIP structure into the lib/silccore/id.h and
5593 replaced the old `ip' fields from all SILC ID's to that type.
5594 This is a step towards IPv6 support.
5596 The silc_id_get_len takes now the ID as an extra argument.
5597 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5598 both IPv4 and IPv6 based ID's.
5600 The affected files are lib/silccore/id.[ch] and other files
5601 around the tree using these routines.
5603 * Removed the ID length arguments in server from various
5604 silc_server_send_notify_* routines -> they are not needed
5607 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Fixed memory leak in silc_encode_pem_file in the file
5610 lib/silcutil/silcutil.c.
5612 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Check minor version as well in the SKE. Affected files are
5615 silcd/protocol.c and lib/silcclient/protocol.c.
5617 * Added --identifier option to the server so that an identifier
5618 can be when creating the public key for the server. Affected
5619 file is silcd/silcd.c.
5621 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5622 lib/silccrypt/silcpkcs.c.
5624 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Register default ciphers and stuff when using -C option with
5627 the server. Affected file sildc/silcd.c.
5629 * Put back the servers public key filename format, it is better
5630 than the new one. For now, the client keys are saved with the
5631 new filename format. The affected file silc/client_ops.c.
5633 * Implemented the Cipher API for the rest of the ciphers that
5634 did not implement it or implemented it the wrong way.
5636 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Register default ciphers and stuff when using the -S option
5639 in the client. Affected file silc/silc.c. Same also when
5640 creating new key pair with -C option.
5642 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Fixed the silc_verify_public_key client operation function to
5645 save the public keys differently. The fingerprint is now
5646 used as filename and not the hostname. This way also the
5647 client keys are saved uniquely and not with hostnames. The
5648 affected file is silc/client_ops.c.
5650 * Trimmed the silc_hash_fingerprint function to remove extra
5651 whitespaces from the end of the fingerprint. The affected
5652 file is lib/silccrypt/silchash.c.
5656 * Added silc_cipher_register_default function to register all
5657 default ciphers. It can be used when configuration files
5658 does not exist and the application does not want any specific
5659 ciphers in any specific order.
5661 The SilcDList is now used as silc_cipher_list dynamically
5662 allocated cipher list. Removed the static list all together
5663 and now all ciphers must be allocated to the dynamic list.
5664 The silc_cipher_alloc routine was changed to check only the
5667 All silc_cipher_* routines that used to return int returns
5670 The affected files lib/silccrypt/silccrypt.[ch].
5672 * The same thing was done to silc_hash_* as for silc_cipher_*
5673 routines. Affected files lib/silccrypt/silchash.[ch].
5675 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5676 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5677 Added also silc_pkcs_[un]register[_default] functions.
5678 Removed the data_context from the PKCS API.
5680 * Added silc_hmac_register_default function to register default
5681 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5682 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5683 to unregister all hmacs at once.
5685 * Register the default ciphers, hash functions, PKCSs and HMACs
5686 if client's configuration file does not exist. The affected
5689 * The client did not load the hash functions from the SIM
5690 modules at all. Added support for this. Affected file is
5691 silc/clientconfig.c.
5693 * When decoding public key with silc_pkcs_public_key_decode, check
5694 the supported algorithm only if PKCS are registered. Affected
5695 file lib/silccrypt/silcpkcs.c. The same was done with the
5696 silc_pkcs_private_key_decode.
5698 * Fixed the SILC List routines to keep the list always in order.
5699 It used to change the list's order when traversing the list but
5700 not it preserves the order. Affected file lib/trq/silclist.h.
5702 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Added the client library to use the SilcSocketConnection's
5705 reference counter (by silc_socket_dup) to prevent the bug that
5706 the socket object may be freed underneath async operation.
5708 * The name resolv library checking fixes in the configure.in.pre.
5711 * Created new version of the protocol drafts for future
5712 development. The -03 drafts are the ones that will be changed
5713 in the trunk now and the -02 will remain as they are.
5715 * Send list of CUMODE notifys to the router when announcing
5716 the channel users to the router. Affected file silcd/server.c.
5717 If the router receiving channel founder CUMODE for a channel
5718 that already has channel founder it will send CUMODE notify
5719 to the sender to remove the channel founder rights from the
5720 announced client. Affected file silcd/packet_receive.c.
5722 * The CUMODE notify may now use Server ID as well as the entity
5723 who changes the mode. Updated protocool specs.
5725 * Updated INSTALL and README files.
5727 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * New web pages in the http://silc.pspt.fi. The pages was
5734 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Implemented the [DenyConnectin] config section in the server.
5737 Added silc_server_config_denied_conn to check whether incoming
5738 connection is denied. Affected file silcd/serverconfig.[ch].
5740 * Do not check the ports when checking the incoming configuration
5741 data if the port is 0, meaning any. Affected file is
5742 silcd/serverconfig.c.
5744 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * Fixed buffer overflow in silc_string_compare in the file
5747 lib/silcutil/silcutil.c.
5749 * Fixed double free in silc_server_command_leave in the file
5752 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Fixed the version checking in the server. Affected file is
5757 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Fixed the configuration data fetching when accepting new
5760 connections in the server. Affected file silcd/server.c.
5762 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Added `sender_entry' argument to the function
5765 silc_server_packet_relay_to_channel so that we can check
5766 whether some destination actually belongs to the same route
5767 the sender belongs (ie, we must not resend the packet to the
5768 sender). Affected file silcd/packet_send.[ch].
5770 * Added `servername' field to the SilcClientEntry in the server
5771 to hold the name of the server where client is from. Affected
5772 file is silcd/idlist.h.
5774 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Moved the channel message encrypting in the router betwen
5777 router connections from silc_server_channel_message to the
5778 silc_server_packet_relay_to_channel since we want to check
5779 whether we have anybody channel before encrypting anything.
5780 Affected files silcd/packet_[receive/send].c.
5782 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Fixed the [AdminConnection] server config section to support
5785 multiple entries. Affected file silcd/serverconfig.c.
5787 * Added support into the server to check the validity of the
5788 incoming connection before executing any KE or authentication
5791 * The connection configuration is now saved to the KE and
5792 connection auth protocol contexts and not fetched anymore in
5793 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5795 * The local hosts listenning address and port is also resolved
5796 now when starting the server. We want to have the socket object
5797 to include the real address and port for the listener. Added
5798 new function silc_net_check_local_by_sock into the files
5799 lib/silcutil/silcnet.[ch].
5801 * Fixed a broadcast bug in server -> do not broadcast if we
5804 * Fixed a routing bug. Do not route broadcast packets ever.
5805 Broadcast packets must be processed always and not routed since
5806 they may be destined to some other host than yourself and thus
5807 would get routed without no good reason. Affected file is
5810 * Added function silc_server_config_is_primary_route to check
5811 whether primary router connection has been configured (a router
5812 configuration that we are initiating). If there is not, we
5813 will assume that there is only two routers in the SILC network
5814 and we will use the incoming router connection as our primary
5815 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5817 * Changed the order of the broadcasting. Broadcast _after_ the
5818 packet has been processed not before. Affected file is
5821 * Fixed a [ClientConnection] parsing bug. The port was never
5822 parsed correctly thus resulting to port 0. Affected file
5823 silcd/serverconfig.c.
5825 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5826 argument and did not set the broadcast packet flag. Affected
5827 file silcd/packet_send.c. Fixed same bug in the function
5828 silc_server_send_notify as well.
5830 * If we receive NEW_ID packet for our own ID in the server, ignore
5833 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Removed the nickname from the Private Message Payload.
5838 Updated the code and the protocol specs.
5840 * Updated protocol specs for submitting to the IETF.
5842 * Tweaked the Random Number Generator a bit. Affected file
5843 lib/silccrypt/silcrng.c. Exported a new function
5844 silc_rng_[global]_add_noise which can be used to add more
5847 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Do not parse packets with different timeout when protocol
5850 is active -> may cause problem with rekey. Affected file
5853 * When server receives signoff notify it must not create
5854 new channel key if the client is on any channels since the
5855 sender of the signoff notify will create it.
5857 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Added printing of error messages during SKE protocol from the
5860 failure packet sent by server during SKE. Affected file
5863 * Removed the client's failure_callback handling with timeout
5864 and handle it immediately when received.
5866 * The SKE library returned wrong type in SUCCESS and FAILURE
5867 packets. They must be 32 bit MSB not 16 bit MSB.
5869 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Ok, rewrote the logic of the re-key and now it seems to work.
5872 I tested it on high traffic with frequent re-keys without
5873 problems. Added hmac_receive (and renamed hmac to hmac_send)
5874 in SilcClientConnection in lib/silcclient/client.h and
5875 in SilcIDListData in silcd/idlist.h. Also, removed the
5876 SilcPacketParserContext's cipher and hmac fields as they are
5877 not needed anymore and actually caused some problems when
5878 the ciphers and hmac's changed underneath the packet parser.
5880 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * If re-key protocol is active then process the incoming packets
5883 synchronously since we must assure that icoming packets encrypted
5884 with the old key is processed before the new keys is set to
5885 use. This is true other packets than for REKEY packets.
5886 Affected file silcd/server.c. The same was done to client library
5887 as well, affected file lib/silcclient/client.c.
5889 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Fixed bug in client and server to accept the force send if
5892 the packet is send from silc_[server/client]_packet_process
5893 function. Otherwise the packets are never delivered, oops.
5895 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Disable force sending of packets when REKEY protocol is active.
5898 We must assure that no packet is sent directly when rekey is
5899 performed. All packets must be sent through packet queue.
5900 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5901 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5902 function is silc_[server/client]_packet_send_real to check
5905 * Replaced the SIM paths from example config files to
5906 /usr/local/modules. Also, make install creates now
5907 /usr/local/silc/logs directory to hold all the SILC server
5910 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Made the configure.in.pre work on Solaris. Patch by salo.
5914 * Made all ciphers compatible with non-x86 machines. Defined
5915 CBC mode macros into lib/silccrypt/ciphers_def.h.
5917 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Fixed the make install.
5921 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * When MAC computation fails the silc_packet_decrypt returned 0
5924 even though it was supposed to return -1. Fixed this. The
5925 affected file is lib/silccore/silcpacket.c.
5927 * Do not replace the config files in /etc/silc (in make install)
5928 if they already exist. Affected file ./Makefile.am.
5930 * Do not send re-key packets immediately but through packet queue.
5931 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5933 * Changed silc_net_check_host_by_sock to return FALSE if the
5934 IP/DNS could not be resolved. Though, it returns the IP address
5935 now even if it could not resolve it (but returns also FALSE).
5936 Affected file lib/silcutil/silcnet.[ch].
5938 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added silc_pkcs_decode_identifier to decode the public key's
5941 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5942 Added also silc_pkcs_free_identifier. Added also new context
5943 SilcPublicKeyIdentifier.
5945 * Added -S option to the silc client. It is used to dump the
5946 contents of the specified public key file.
5948 * Changed the PKCS api to return the public key length when
5949 setting the public key.
5951 * Fixed a fatal bug in the public and private key file loading.
5952 Affected file lib/silccrypt/silcpkcs.c.
5954 * Execute the packet parsing for client with zero (0) timeout
5955 if the protocol is active. Affected file silcd/server.c.
5957 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Made the key generation options to the silcd program. Added
5960 -C option, equivalent to client's option.
5962 * Added new [ServerKeys] config section to the server. It
5963 configures the server's public and private key.
5965 * Defined generic Public Key Payload into the protocol
5966 specification to send specific type of public keys and
5969 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5970 public key or certificate.
5972 * Implemented the GETKEY command to the server and to the
5973 client library and on user interface.
5975 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Made preliminary `make install' work.
5979 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Added SilcServerRekey context into silcd/idlist.h.
5983 * Added the PFS support as defined in the specification to the
5984 SKE protocol. Affected files lib/silcske/*.c.
5986 * Added `ske_group' field to the SilcServerRekey context to hold
5987 the number of the SKE group that is used with PFS in re-key.
5988 Affected file silcd/idlist.h.
5990 * Added PFS re-key support to the server. Affected file is
5993 * Added silc_protocol_cancel to cancel execution of the next
5994 state of the protocol. Affected file is
5995 lib/silccore/silcprotocol.[ch].
5997 * Added the re-key support with and without PFS to the client
5998 library. Re-key is performed once in an hour, by default.
6000 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6001 Added silc_client_rekey_callback and silc_client_rekey_final.
6002 Affected files are lib/silcclient/protocol.[ch] and
6003 lib/silcclient/client.[ch].
6005 * Removed the `hmac_key' and `hmac_key_len' fields from the
6006 SilcClientConnection structure; not needed. Affected file is
6007 lib/silcclient/client.h.
6011 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Do not ask whether user wants to use the negotiated private key
6014 for private messages, just use it. Affected file is
6015 silc/local_command.c.
6017 * Added `send_enc_key' and `enc_key_len' fields to the
6018 SilcIDListData structure since they are needed in the re-key
6019 phase. Affected file is silcd/idlist.[ch].
6021 * Implemented the simple re-key protocol into the server.
6022 Affected files silcd/server.c and silcd/protocol.[ch]. The
6023 re-key will be performed once in an hour, by default.
6025 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6026 Added silc_server_rekey, silc_server_rekey_callback and
6027 silc_server_rekey_final.
6029 * Removed Tunneled flag from the protocol. Updated the code
6030 and the specifications.
6032 * Adde `pfs' field to the SilcIDListData to indicate whether
6033 the PFS is to be performed in the re-key. Affected file is
6036 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6039 int64 of at least the xintXX size. If void * is less that 4
6040 bytes uint32 * will be used. Defined bool as boolean.
6042 * Changed _ALL_ unsigned long and unsigned int to uint32,
6043 unsgined short to uint16 in the source tree.
6045 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6046 not handle clients that has entry->data.registered == FALSE.
6047 They are not in the network anymore. Affected file is
6050 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Implemented the sending of the SERVER_SIGNOFF notify in the
6053 server. Affected file is silcd/server.c.
6055 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6056 Added also silc_notify_payload_encode_args into the
6057 lib/silccore/silcnotify.[ch].
6059 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6060 Affected file silcd/packet_receive.c.
6062 * Implemented the SERVER_SIGNOFF notify handling in the client
6063 library. Affected file lib/silcclient/client_notify.c. Also,
6064 implemnted the printing of the SERVER_SIGNOFF info to the
6065 application. Affected file silc/client_ops.c.
6067 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6068 if the deleting was successful. Affected file silcd/idlist.[ch].
6070 * Added support for public key authentication in the connection
6071 authentication protocol in the client library. Affected file
6072 lib/silcclient/protocol.c.
6074 * Changed the server's silc_idlist_get_clients_by_* interface
6075 to support already allocated array so that new entries may be
6076 added to pre-allocated array. Affected file silcd/idlist.[ch].
6077 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6078 and command replies.
6080 * All command reply functions in the server now calls the
6081 pending command callback even if error occured. This way the
6082 error will be delivered to the client as well. Affected files
6083 silcd/command.c and silcd/command_reply.c.
6085 * Fixed INFO command to return local server's info if no server
6086 was provided. Affected file lib/silcclient/command.c.
6088 * Removed RESTART command for good. Updated the code and the
6091 * Rewrote parts of the task system. It is a bit simpler now.
6092 Removed unsued task priorities. The affected files are
6093 lib/silcutil/silctask.[ch].
6095 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Moved the USERS printing from the library to the application.
6098 Affected files lib/silcclient/command.c and silc/client_ops.c.
6100 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Added channel key re-key support. The re-key is perfomed
6105 only by the router and is done once in an hour. Added `rekey'
6106 field to the SilcChannelEntry in the server. Affected files
6107 silcd/server.c and silcd/idlist.h.
6109 * Added silc_task_unregister_by_context into the file
6110 lib/silcutil/silctask.[ch].
6112 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Added SILC_UMODE_GONE mode to indicate when the client is not
6115 present in the SILC network. Added also support to the local
6116 command AWAY that will set this mode. Added support of showing
6117 "xxx is gone" in WHOIS command. The USERS command shows the
6118 gone status as well.
6120 * Fixed setting server and router operator privileges in the
6121 server's UMODE command. Affected file silcd/command.c.
6123 * Merged the SKE KE1 and KE2 payloads into one payload. The
6124 new KE payload is equivalent to the old KE2 payload.
6126 Cleaned up the SKE Start Payload parsing. It now uses the
6127 simple buffer unformatting to do the parsing. A lot faster
6130 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6131 to the SKE that is used to indicate whether both of the SKE
6132 parties should perform authentication. By default only the
6133 responder performs authentication. By setting this flag also
6134 the initiator must do authentication. By default it is unset
6135 since in normal SKE case, client to server connection, only
6136 the responder should do authentication. When doing SKE between
6137 two clients both should perform authentication. Updated the
6138 code and the protocol specs.
6140 * A little fix to IDENTIFY command in the server. Search the
6141 client first by hash not nickname. Affected file is
6144 * Fixed the silc_client_close_connection to support closing
6145 the client to client connections wihtout deleting too much
6146 data. Affected file lib/silcclient/client.c.
6148 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6149 are received if protocol used to be active but is not anymore
6150 the application would crash due to NULL pointer dereference.
6151 Affected files silcd/server.c and lib/silcclient/client.c.
6153 * Added `hash' field to the SilcClientConnection to include
6154 the hash function negotiated in the SKE protocol.
6156 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6157 to set the channel founder authentication data. A client can
6158 claim the founder rights later by providing the authentication
6159 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6160 This way the channel founder can regain the channel founder
6161 privileges even it is left the channel. This works only on
6162 local server and the client must be connected to the same
6163 server to be able to regain the founder rights. Updated the
6164 protocol specs accordingly.
6166 Added support to the CMODE command in the client to set the
6167 founder auth data. Read the README to see how to set it.
6169 Added support to the CUMODE command to claim the founder
6170 rights. Read the README to see how to do it.
6172 Added support for the founder authentication to the Channel
6173 Entry in the server. Affected file silcd/idlist.h.
6175 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6176 server's CMODE command. Affected file silcd/command.c.
6178 * Added the following new functions into lib/silccore/silcauth.[ch]:
6179 silc_auth_get_method and silc_auth_get_data.
6181 * The server now saves the remote hosts public key to the
6182 SilcIDListData pointer. Affected file silcd/protocol.c.
6184 * The normal server now does not remove the channel entry from
6185 the cache if the founder authentication data is set. It used
6186 to remove it if the founder was the last one on the channel on
6187 the server and left the channel. The auth data is saved and
6188 if the channel is re-joined later the old entry is used with
6189 the old auth data. Affected files silcd/command_reply.c and
6192 * Removed the `pkcs' field from the SilcIDListData structure
6193 in the server; it is not used. Affected file silcd/idlist.h.
6195 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Fixed packet processing on slow links. Partial packets were
6198 never re-processed because the incoming data buffer was cleared
6199 by the application. Application must not directly clear the
6200 sock->inbuf, the packet processing routines handle it. Fixed
6201 this in client library and in server.
6203 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * Fixed the WHOIS and IDENTIFY send reply function to really
6206 check whether to send list or just one entry. Affected file
6209 * Cleaned up the LEAVE command's channel key distribution. The
6210 affected file silcd/command.c.
6212 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6213 can enforce the channel mode as well. In that case the ID
6214 includes the ID of the server. The code now enforces the
6215 mode change if the router have different mode than the server.
6217 * The notify client operation with CMODE_CHANGE notify can now
6218 return NULL client_entry pointer if the CMODE was not changed
6219 by client. Application must check for this.
6221 * Added <Server ID> argument to INFO command to support server
6222 info fetching by Server ID.
6224 * Added silc_server_announce_get_channel_users to get assembled
6225 packets of channel users of the specified channel. Affected
6226 file silcd/server.[ch].
6228 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6229 was freed underneath the ID Cache.
6231 * Re-announce clients when the server received CHANNEL_CHANGE
6232 notify from the router. Affected file silcd/packet_send.c.
6234 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6237 crashed since it did not handle the fact that there is no cipher
6238 called "3" and didn't check the error condition. Now fixed.
6240 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6241 flag. It can be used to send message requests.
6243 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6245 * Implemented the RESTART command in the client.
6247 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6248 notice type messages. Added notice printing to the user
6251 * The channel keys are not re-generated if the channel's mode
6252 is PRIVKEY, ie private key on the channel exists. Affected
6253 files silcd/server.c and silcd/command.c.
6255 * Fixed a little bug in channel message delivery when channel
6256 private keys are set in the server. Affected file is
6257 silcd/packet_send.c.
6259 * Changed the setting on channel->on_channel = TRUE from the
6260 silc_client_save_channel_key to the JOIN command reply. The
6261 key payload is not received if the private channel key is set.
6262 Affected file lib/silcclient/command_reply.c and the
6263 lib/silcclient/client_channel.c.
6265 * When the CMODE_CHANGE notify is sent and the channel private
6266 key mode is removed the channel key must be re-generated in
6267 other cells as well. Added this support for the router in the
6268 silcd/packet_receive.c.
6270 * Added new local command NOTICE to send notice message on
6271 channel. Affected file silc/local_command.[ch].
6273 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Added new local command ME to the client. It is used to send
6276 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6277 some action. Affected file silc/local_command.[ch].
6279 * Changed channel_message and private_message client operations
6280 to deliver the message flags to the application. Added also
6281 the `flags' arguments to the silc_client_send_channel_message
6282 and silc_client_send_private_message functions. Affected file
6285 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Redefined the Private Message Payload to support private message
6288 keys and to support the new private message flags. Updated
6289 the protocol specs. Flags makes it possible to have for example
6290 CTCP style messages.
6292 * Added new type SilcPrivateMessagePayload and defined an API
6293 for it in the lib/silcclient/silcprivate.[ch].
6295 * Tested private message private keys successfully. Tested the
6296 private message key set, unset and list commands with the new
6299 * Redefined the Channel Message Payload to include the channel
6300 message flags (equal with private message flags) to support
6301 for example CTCP style messages.
6303 * Defined some of the message (for channel and private message)
6304 flags. Updated the protocol specs and added the flags to the
6305 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6307 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Added SilcKeyAgreementStatus type to the key agreement routines
6310 to indicate the current status and error if one occured.
6311 The status types are defined in the lib/silcclient/silcapi.h.
6313 * Added new local command KEY that is used to set and unset private
6314 keys for channels, set and unset private keys for private messages
6315 with remote clients and to send key agreement requests and
6316 negotiate the key agreement protocol with remote client. The
6317 key agreement is supported only to negotiate private message keys,
6318 it currently cannot be used to negotiate private keys for channels,
6319 as it is not convenient for that purpose.
6321 * Fixed a minor pending callback setting bug in the function
6322 silc_client_get_client_by_id_resolve, now the function works.
6323 Affected file lib/silcclient/idlist.c.
6325 * Added function silc_net_get_local_port to get local bound
6326 port by socket. Added to lib/silcutil/silcnet.[ch].
6328 * Added `sockets' and `sockets_count' fields to the SilcClient
6329 object. They hold the sockets of the listenning sockets in
6330 the client. Listenning sockets may be for example the key
6331 agreement server. Affected file lib/silcclient/client.[ch].
6332 Added functions the silc_client_add_socket and the
6333 silc_client_del_socket. They are exported to the application
6336 * Added ~./silc/clientkeys to support other client's public keys.
6338 * Renamed verify_server_key client operation to verify_public_key
6339 and added one argument to indicate the type of the connection
6340 (server, client etc.).
6342 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Added silc_server_connection_auth_request to handle the
6345 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6346 silcd/packet_receive.[ch].
6348 * Added silc_server_send_connection_auth_request into the
6349 silcd/packet_send.c to send the connection auth request packet.
6351 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6354 * Fixed the public key authentication in responder side in the
6355 server. The `auth_data' pointer includes the SilcPublicKey
6356 not the path to the public key. Affected file silcd/protocol.c.
6358 * Implemented the public key authentication in the initiator side
6359 in the server. Affected file silcd/protocol.c.
6361 * Removed the [RedirectClient] config section from the server
6362 configuration. Is not needed and I don't want to implement it.
6364 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Cleaned up the CMODE command in the server. It now works
6367 correctly and supports all the modes defined in the protocol.
6368 Affected file is silcd/command.c.
6370 * Added `hmac_name' field to the SilcChannelEntry in the server
6371 to hold the default HMAC of the channel. It can be set when
6372 creating the channel (with JOIN command). Affected files
6375 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6376 type to indicate the change of the current cipher and hmac
6377 on the channel. Client can safely ignore the <cipher> argument
6378 (if it chooses to do so) since the CHANNEL_KEY packet will
6379 force the channel key change anyway. The <hmac> argument is
6380 important since the client is responsible of setting the new
6381 HMAC and the hmac key into use.
6383 * Fixed the CMODE command in the client library as well.
6385 * Tested CMODE command in router environment successfully.
6387 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Show the version of the remote client (or server) when connecting
6390 to the server. It is logged to the log file. Affected file
6391 is silcd/protocol.c.
6393 * Fixed the KILLED notify handling in the client library. The
6394 client must be removed from all channels when receiving the
6397 Also, do not remove the client entry when giving the KILL
6398 command but when the KILLED notify is received.
6400 * Removed silc_idlist_find_client_by_nickname from the server.
6401 Not needed anymore. Affected files silcd/idlist.[ch].
6403 * Implemented the CHANNEL_CHANGE notify type handling to the
6404 server. Affected file silcd/server.c.
6408 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Added silc_server_send_notify_invite to send the INVITE
6411 notify between routers.
6413 * Implemented the INVITE command correctly to the server.
6415 * Implemented the INVITE notify type handling in the server.
6417 * Implemented the INVITE command to the client library and on the
6420 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Added function silc_server_get_client_resolve to find the
6423 client entry by ID from all ID lists and then resolve it
6424 (using WHOIS) if it cannot be found. Affected file is
6427 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Implemented the BAN command to the client library.
6431 * The JOIN command in the server now checks the invite list
6434 * Changed the silc_command_reply_payload_encode_va and the
6435 silc_command_payload_encode_va to support that if argument is
6436 NULL it ignores and checks the next argument. Affected file
6437 lib/silccore/silccommand.c.
6439 * Added silc_server_send_notify_ban to send the BAN notify
6440 type between routers.
6442 * Chaned the silc_notify_payload_encode to support that if
6443 argument is NULL it ignores and checks the next argument.
6444 Affected file lib/silccore/silcnotify.c.
6446 * Tested ban lists in router environment successfully.
6448 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Implemented BAN command to the server, in silcd/command.[ch].
6452 * Removed the BAN and INVITE_LIST modes from the CMODE command
6455 * Added function silc_string_match to regex match two strings.
6456 Affected files lib/silcutil/silcutil.[ch].
6458 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Redefined parts of the SilcChannelEntry in the server to support
6461 the new ban and invite lists.
6463 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6465 * Redefined the INVITE command. The same command can be used to
6466 invite individuals to the channel but also to manage the invite
6467 list of the channel (to add to and remove from the invite list).
6468 Updated the protocol specs.
6470 * Added new command SILC_COMMAND_BAN that can be used to manage
6471 the ban list of the channel. Updated the protocol specs.
6473 * Removed the channel modes: the SILC_CMODE_BAN and the
6474 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6475 in the CMODE command. The equivalent features are now available
6476 using INVITE and BAN commands. Updated the protocol specs.
6478 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6479 in the network about change in the current ban list. The notify
6480 type is not used by the client.
6482 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6483 support the invite lists.
6485 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Added new function silc_string_regexify that converts string
6488 including wildcard characters into regex string that can
6489 be used by the GNU regex library. Added into the file
6490 lib/silcutil/silcutil.[ch].
6492 Added silc_string_regex_combine to combine to regex strings
6493 into one so that they can be used as one regex string by
6494 the GNU regex library. Added into the file
6495 lib/silcutil/silcutil.[ch].
6497 Added silc_string_regex_match to match two strings. It returns
6498 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6500 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Imported GNU regex to the soruce tree into lib/contrib.
6503 Fixed some compiler warning from the regex.c.
6505 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Fixed MOTD command in the server to work in router environment.
6509 * Fixed the MOTD command in the client library to support
6510 the server argument in the command.
6512 * Added `nickname_len' argument to the silc_idlist_add_client
6513 in the server, as the `nickname' argument may be binary data
6516 * Added silc_idlist_get_channels to return all channels from
6519 * Implemented LIST command to the server. Affected file is
6522 * Implemented the LIST command to the client library and on the
6525 * Added [<user count>] argument to the LIST command reply.
6526 With private channels the user count is not shown.
6528 * Updated TODO and README.
6530 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * The client entry's data.registered must be TRUE even with
6533 global client entry on global client list. The data.registered
6534 is used to check whether the client is anymore in the network,
6535 for example with WHOWAS command so it must be valid.
6537 * Fixed the WHOWAS command in the server. It now actually works
6538 in router environment. Added function into silcd/command_reply.c
6539 silc_server_command_reply_whowas_save.
6541 * Added silc_idlist_purge function to the silcd/idlist.c
6542 to periodically purge the ID Cache.
6544 * Fixed INFO command in the server. It works now in router
6545 environment. Added <server name> argument to the INFO command
6546 reply. Updated the protocol specs.
6548 * Fixed minor bug in silc_idcache_purge to not purge if the
6549 expire value is zero.
6551 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6552 they were buggy because of the WHOWAS information.
6554 * Fixed local command MSG to handle the async resolving of
6555 the remote client properly. It used to fail the first MSG.
6556 Affected file silc/local_command.c.
6558 * Added `data_len' field to SilcIDCache context.
6560 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Update TODO. Todo in commands in the server.
6564 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6567 used by routers as broadcast packet to inform other routers
6568 about the changed user mode.
6570 Implemented the notify handling in the server. Affected file is
6571 silcd/packet_receive.c. Added the function
6572 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6574 * Added new generic Channel Payload and deprecated the New Channel
6575 Payload. The New Channel Payload is now the generic Channel
6578 * Added new argument `mode' to the silc_server_send_new_channel
6579 as it is required in the Channel Payload now.
6581 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6582 and created a new and real SilChannelPayload to represent the
6583 new generic Channel Payload. Implemented the encode/decode
6584 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6586 * Added silc_server_get_client_channel_list to return the list
6587 of channels the client has joined for WHOIS command reply.
6588 Affected file silcd/server.[ch].
6590 * Implemented the channel list sending in the WHOIS command reply
6591 in server and in the client.
6593 Implemented the channel list displaying on the user interface
6594 as well. Affected file silc/client_ops.c.
6596 * Added silc_channel_payload_parse_list to parse list of Channel
6597 Payloads. It returns SilcDList list of SilcChannelPayloads.
6598 Client for example can use this function to parse the list of
6599 channels it receives in the WHOIS command reply. The caller
6600 must free the list by calling silc_channel_payload_list_free.
6601 Affected files lib/silccore/silcchannel.[ch].
6603 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Added one new argument <user mode> to the WHOIS command reply
6606 to return the mode of the user in SILC. Updated the protocol
6609 Implemented it to the server and client.
6611 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * Fixed the mode printing on the user interface on joining.
6614 Affected file silc/client_ops.c.
6616 * Implemented the UMODE command and user modes in general to the
6617 client library and to the user interface.
6619 * Implemented the UMODE command to the server.
6621 * The server now sends UNKNOWN_COMMAND error status if client sends
6622 unknown command. Affected file silcd/command.c.
6624 * All server commands now handle the command identifier the right
6625 way when sending the command reply to the client. The client can
6626 use to identify the command replies with the identifier.
6628 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Added silc_server_get_client_route to resolve the route to
6631 the client indicated by the client ID. Affected file is
6634 * Added silc_server_relay_packet as general function to relay
6635 packet to arbitrary destination. This deprecates functions
6636 like _send_private_message_key, _relay_notify etc. Affected
6637 file is silcd/packet_send.[ch].
6639 Removed silc_server_send_key_agreement,
6640 silc_server_send_private_message_key and
6641 silc_server_packet_relay_notify functions from the file
6642 silcd/packet_send.[ch].
6646 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6647 server. Affected file silcd/packet_receive.[ch].
6649 * Implemented the KILL command to the client. Implemented the
6650 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6651 Affected files lib/silcclient/command[_reply].c and
6652 lib/silcclient/client_notify.c. Implemented the KILL notify
6653 printing in the user inteface.
6655 * Fixed a lot silc_parse_nick memory leaks from the client
6656 library in the file lib/silcclient/command.c.
6658 * Changed the silc_server_send_notify_on_channels's `sender'
6659 argument from SilcSocketConnection to SilcClientEntry to
6660 check the sender as entry and not as connection object and not
6661 to send to the client provided as argument. The affected file
6662 is silcd/packet_send.[ch].
6664 * The notify packets that are destined directly to the client used
6665 to not to be processed by the server. Now changed that and the
6666 server processes all notify packets. After relaying the packet
6667 to the client the notify packet is processed in the server.
6669 * The silc_server_free_client_data now checks whether there is
6670 pending outgoing traffic for the client and purges the data to
6671 the network before removing the client entry.
6673 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6676 an client is killed from the SILC Network. Updated the protocol
6679 Added new function silc_server_send_notify_killed to the
6680 silcd/packet_send.[ch].
6682 * Added function silc_server_packet_relay_notify to relay notify
6683 packets that are destined directly to a client. In this case
6684 the server does not process the notify packets but merely relays
6685 it to the client. Affected file silcd/packet_send.[ch].
6687 Added also silc_server_packet_process_relay_notify to check
6688 whereto relay the notify. Affected file is
6689 silcd/packet_receive.[ch].
6691 * Implemented the KILL command to the server.
6695 * Added the backup schema desgined last fall to the protocol
6696 specs for everyone to see. The specification is in the
6697 *-spec-xx.txt draft and the packet type definitions for the
6698 backup routers is in *-pp-xx.txt draft. Thusly, added also
6699 new packet type SILC_PACKET_CELL_ROUTERS.
6701 * A big security problem in the implementation discovered. The
6702 signoff of an client did not cause new channel key generation
6703 which it of course should've done. The channel keys must be
6704 always re-generated when client leaves (or signoffs) the channel.
6705 The silc_server_remove_from_channels funtion now handles
6706 the channel key re-generation.
6708 * Added `sender' argument to the silc_server_send_notify_on_channels
6709 to not to send the client provided as argument. Affected file
6710 silcd/packet_send.[ch].
6712 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Implemented OPER and SILCOPER commands into the server and
6717 * Added silc_auth_verify and silc_auth_verify_data to verify
6718 the authentication directly from the authentication payload.
6719 It supports verifying both passphrase and public key based
6720 authentication. Affected file lib/silccore/silcauth.[ch].
6722 * Added `hash' field to the SilcIDListData structure. It is the
6723 hash negotiated in the SKE protocol. Affected file is
6726 * Slight redesigning of the SilcAuthPayload handling routines.
6727 Do not send SilcPKCS but SilcPublicKey as argument.
6729 * Implemented the public key authentication support to the
6730 serverconfig. The public key is loaded from the provided path
6731 and saved as authentication data to void * pointer. Thus,
6732 changed the unsigned char *auth_data to void *auth_data;
6734 * Fixed SHUTDOWN command to send the reply before the server
6735 is shutdown. :) Affected file silcd/command.c.
6737 * Fixed fatal bug in CONNECT command. The hostname was invalid
6738 memory and server crashed. Affected file silcd/command.c.
6740 * Fixed fatal bug in CLOSE command. The server_entry became
6741 invalid but was referenced later in the command. Affected file
6744 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Fixed fatal bug in failure packet handling. Server ignored
6747 the failure and thus crashed when it came.
6751 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6754 that the command may be executed only once in (about) 2 seconds.
6755 The old SILC_CF_LAG flag is same but allows command bursts up
6756 to five before limiting.
6758 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6759 server code. Various commands now includes the CF_LAG_STRICT
6760 flag to disallow any kind of miss-use of the command.
6762 * Fixed the silc_buffer_unformat to not to allocate any data
6763 if the length of the data is zero. It used to allocate the
6764 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6766 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Changed the format of AdminConnection configuration section
6769 in the server. Added username of the admin to the format.
6770 Affected files silcd/serverconfig.[ch].
6772 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6773 to return admin configuration data by host, username and/or
6776 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Implemented WHOWAS command to the server. Added the functions:
6780 silc_server_command_whowas_parse,
6781 silc_server_command_whowas_send_reply,
6782 silc_server_command_whowas_from_client and
6783 silc_server_command_whowas_from_server
6785 * Added <Client ID> argument to the WHOWAS command reply. Updated
6786 the protocol specs accordingly.
6788 * Implemented WHOWAS command and command_reply to the client
6791 Implemented the WHOWAS printing on the user interface.
6793 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Added new argument to the WHOWAS command reply, the real name.
6796 It is an optional argument. Updated the protocol specs.
6798 * Added SilcIDCacheDestructor callback that is registered when
6799 the SilcIDCache is allocated. The callback is called when
6800 an cache entry in the ID Cache expires, or is purged from the
6801 cache. Added into lib/silccore/idcache.[ch].
6803 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6804 to destruct the client entries when the cache entry expires.
6805 Other ID Cache's in server and in the client library ignores
6808 * If the ID Cache entry's `expire' field is zero then the entry
6809 never expires. Added boolean `expire' argument to the
6810 silc_idcache_add function in the lib/silccore/idcache.[ch].
6811 If it is TRUE the default expiry value is used.
6813 * Added silc_server_free_client_data_timeout that is registered
6814 when client disconnects. By default for 5 minutes we preserve
6815 the client entry for history - for WHOWAS command.
6817 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Added support to the server to enforce that commands are not
6820 executed more than once in 2 seconds. If server receives
6821 commands from client more frequently, timeout is registered
6822 to process the commands. Affected file silcd/command.c.
6823 Added new function silc_server_command_process_timeout.
6825 * Changed NICK_NOTIFY handling in client library to check that
6826 if the client's nickname was changed, so there is no need to
6827 resolve anything from the server.
6829 * Removed error printing from the WHOIS and IDENTIFY commands.
6830 If error occurs then it is ignored silently in the client library.
6831 The application, however, may map the received error to
6832 human readable error string. The application currently maps
6833 the NO_SUCH_NICKNAME error to string.
6835 * Made the command status message public to the application. Moved
6836 them from lib/silcclient/command_reply.c to
6837 lib/silcclient/command_reply.h. The application can map the
6838 received command status to the string with the
6839 silc_client_command_status_message function.
6841 * Added check to the server to check that client's ID is same
6842 as the Source ID in the packet the client sent. They must
6845 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Added dist-bzip hook to the Makefile.am to make bzip2
6848 compressed distributions.
6850 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Server now enforces the maximum length for the nickname and
6853 the channel as protocol specification dictates. 128 bytes for
6854 nickname and 256 bytes for channel name.
6856 * Moved the WHOIS printing to the application. The client libary
6857 does not print out the WHOIS information anymore, the application
6858 must do it. Renamed silc_client_command_reply_whois_print to
6859 the silc_client_command_reply_whois_save.
6861 The client's idle time is also sent to the application now, and
6862 the idle is shown on screen.
6864 * Added silc_client_command_reply_identify_save to save the
6865 received IDENTIFY entries.
6867 * Do not check for channel private keys in message sending and
6868 reception if the channel does not have the PRIVKEY mode set.
6869 Affected file lib/silclient/client_channel.c.
6871 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6874 just surfaced after chaning the JOIN procedure.
6876 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6878 * Added silc_client_get_clients_by_list to get client entries
6879 from Client ID list, that is returned for example by JOIN
6880 and USERS command replies. The application should use this
6881 function for example when JOIN command reply is received to
6882 resolve the clients already on the channel (library does not
6883 do that anymore as USERS command reply is not used in the JOIN
6884 procedure anymore). Affected files lib/silcclient/silcapi.h and
6885 lib/silcclient/idlist.c.
6887 * JOIN command reply and USERS command reply returns now SilcBuffer
6888 pointers instead of unsigned char pointers when returning
6889 the client list and mode list.
6891 * Added <Client ID> argument to the JOIN command reply, mainly
6892 for the server to identify for which client the command was
6893 originally sent. Updated protocol specs accordingly.
6895 * Added SilcDlist private_key pointer to the SilcChannelEntry
6896 in the client to support the channel private keys. Affected
6897 file is lib/silcclient/idlist.h.
6899 * Added SilcChannelPrivateKey argument to the function
6900 silc_client_send_channel_message so that application can choose
6901 to use specific private ke if it wants to. If it is not provided,
6902 the normal channel key is used, unless private keys are set.
6903 In this case the first (key that was added first) is used
6904 as the encryption key.
6906 * Implemented the support for channel private key handling.
6907 Implemented the following functions:
6909 silc_client_add_channel_private_key,
6910 silc_client_del_channel_private_keys,
6911 silc_client_del_channel_private_key,
6912 silc_client_list_channel_private_keys and
6913 silc_client_free_channel_private_keys
6915 Affected file lib/silcclient/client_channel.c.
6917 * Added the support for the private keys in the channel message
6918 sending and encryption and in the message reception and
6919 decryption. Affected funtions are
6920 silc_client_send_channel_message and silc_client_channel_message.
6922 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6924 * Added SKE's key verify callback to the client library's
6925 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6927 * Removed the statement that server (or router) must send USERS
6928 command reply when joining to the channel so that the client
6929 knows who are on the channel. Instead, the client list and
6930 client's mode list is now sent in the JOIN command reply to the
6931 client who joined channel. This is better solution.
6933 * Added function silc_server_get_users_on_channel and function
6934 silc_server_save_users_on_channel to the silcd/server.[ch].
6936 * Removed function silc_server_command_send_users from the
6939 * Do not show topic on the client library anymore. The topic is
6940 sent in the command reply notify to the application and the
6941 application must show the topic now.
6943 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Added client searching by nickname hash into the IDENTIFY and
6946 WHOIS commands in the server as they were clearly missing from
6947 them. Affected file is silcd/command.c.
6949 * Fixed a bug in private message receiving in the client library.
6950 The remote ID was freed and it wasn't supposed, now it is
6953 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Minor fix to the channel payload; allocate the data area, as it
6956 needs to be of specific length.
6958 * If the key agreement port is zero then the operating
6959 system will define the bound port. Affected files are
6960 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6962 * Added new function silc_channel_payload_decrypt into the file
6963 lib/silccore/silcchannel.[ch].
6965 * Moved the channel message etc, check from silc_packet_decrypt
6966 to applications. The library calls now a generic
6967 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6968 when the packet is either normal or special. This was done to
6969 allow more wide range of checking that was not allowed when
6970 the code was in library. Now applications can do virtually any
6971 checks to the packet and return to the library the decision how
6972 the packet should be processed. Affected files are
6973 lib/silccore/silcpacket.[ch].
6975 Added silc_server_packet_decrypt_check to the server and
6976 silc_client_packet_decrypt_check to the client library.
6978 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6979 to send with specified source and destination information.
6981 * Channel message delivery between routers was broken after the
6982 channel key distribution was fixed earlier. The channel key
6983 was used be to distributed to other routers as well which is not
6984 allowed by the protocol. Now this is fixed and channel keys
6985 really are cell specific and the channel message delivery between
6986 routers comply with the protocol specification.
6988 * Fixed various commands in server to check also the global list
6989 for the channel entry and not just the local list. The affected
6990 file silcd/command.c.
6992 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Added assert()s to buffer formatting and unformatting routines
6995 to assert (if --enable-debug) when error occurs. Affected
6996 file: lib/silcutil/silcbuffmt.c.
6998 * Changed to auto-reconnect to check whether the remote host is
6999 router and register the re-connect timeout if it is. It used
7000 to check that whether we are normal server, but router must do
7001 auto-reconnect with another router as well. Affected file
7004 * Removed the [<key len>] option from CMODE command as the cipher
7005 name decides the key length, nowadays. See the defined ciphers
7006 from the protocol specification.
7008 * Added [<hmac>] option to the CMODE command to define the HMAC
7009 for the channel. Added SILC_CMODE_HMAC channel mode.
7011 * Added [<hmac>] option for the JOIN command so that user can
7012 select which HMAC is used to compute the MACs of the channel
7015 * Added Hmac field to the Channel Message Payload. The integrity
7016 of plaintext channel messages are now protected by computing
7017 MAC of the message and attaching the MAC to the payload. The
7018 MAC is encrypted. Now, it is clear that this causes some
7019 overhead to the size of the packet but rationale for this is that
7020 now the receiver can verify whether the channel message decrypted
7021 correctly and also when private keys are set for the channel the
7022 receiver can decrypt the packet with several keys and check from
7023 the MAC which key decrypted the message correctly.
7025 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7026 lib/silccrypt/silccipher.[ch].
7028 * Added silc_hash_len to return the digest length into the
7029 lib/silcrypt/silchash.[ch].
7031 * Rewrote parts of Silc Channel Payload interface in the
7032 lib/silccore/silcchannel.[ch]. The encode function now also
7033 encrypts the packet and parse function decrypts it.
7035 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * Fixed a minor formatting bug in the SKE's key material processing.
7038 It actually might have processed the keys wrong way resulting
7041 * Redefined the mandatory HMAC algorithms and added new algorithms.
7042 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7043 and hmac-md5 truncated to 96 bits. The mandatory is now
7044 hmac-sha1-96. Rest are optional (including the one that used
7045 to be mandatory). Rationale for this is that the truncated HMAC
7046 length is sufficient from security point of view and can actually
7047 make the attack against the HMAC harder. Also, the truncated
7048 HMAC causes less overhead to the packets. See the RFC2104 for
7051 * Added new [hmac] configuration section. The SKE used to use
7052 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7053 is of course wrong. The official names that must be proposed in
7054 the SKE are the ones defined in the protocol specification
7055 (hmac-sha1-96 for example). The user can configure any hmac
7056 using any hash function configured in the [hash] section. At
7057 least, the mandatory must be configured.
7059 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7061 * Added HMAC list to the SKE proposal list. It has now both
7062 hash algorithm list and HMAC list. This makes the protocol
7063 incompatible with previous versions. The SKE now seems to work
7064 the way it is supposed to work, for the first time actually.
7066 * Defined plain Hash algorithms to the protocol specification.
7069 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Implemented support for key agreement packets into the server.
7072 Added functions silc_server_key_agreement and
7073 silc_server_send_key_agreement. Other than these functions,
7074 server has nothing to do with this packet.
7076 * Added support for private message key packets into the server.
7077 Added functions silc_server_private_message_key and
7078 silc_server_send_private_message_key.
7082 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7083 called in the protocol's final callback instead in the END
7084 protocol state. This makes a little more sense and in the same
7085 time in client we can use the same protocol routines for normal
7086 key exchange and to key agreement packet handling as well.
7088 * Added to both client's and server's KE protocol context the
7089 SilcSKEKeyMaterial pointer to save the key material. We will
7090 bring the key material to the protocol's final callback by doing
7091 this. The final callback must free the key material.
7093 * Added SKE's packet_send callback into client's KE protocol
7094 context so that the caller can choose what packet sending function
7095 is used. This way we can use different packet sending when
7096 doing normal SKE when doing key agreement packet handling (in
7097 the key agreement packet handling we do not want to encrypt
7100 * Implemented the responder side of the key agreement routines
7101 in the client. The client can now bind to specified port and
7102 accept incoming key negotiation. The key material is passed
7103 to the application after the protocol is over.
7105 * Implemented the processing of incoming Key Agreement packet
7106 in the client. Added function silc_client_key_agreement to
7109 * Implemented the intiator side of the key agreement routines
7110 in the client. The client can now initiate key agreement with
7111 another remote client. The key material is passed to the
7112 application after the protocol is over.
7114 * Created client_keyagr.c to include all the key agreement
7117 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7118 SILC_TASK_CALLBACK except that it is not static.
7120 * Created client_notify.c and moved the Notify packet handling
7121 from the client.[ch] into that file.
7123 * Created client_prvmsg.c and moved all private message and
7124 private message key routines from the client.[ch] into that file.
7126 * Create client_channel.c and moved all channel message and
7127 channel private key routines from the client.[ch] into that file.
7129 * Changed silc_client_get_client_by_id_resolve to resolve with
7130 WHOIS command instead of IDENTIFY command, in the file
7131 lib/silclient/idlist.c.
7133 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * Implemented the SKE's responder side to the Client library.
7137 * When FAILURE is received to the protocol do not trust it
7138 blindly. Register a timeout to wait whether the remote closes
7139 the connection as it should do it, only after that process the
7140 actual failure. This was changed to both client and server.
7142 * Added client_internal.h to include some of the structures
7143 there instead of client.h in lib/silcclient/.
7145 * Added function silc_task_unregister_by_callback to unregister
7146 timeouts by the callback function.
7148 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Some "Incomplete WHOIS info" errors has been appearing on the
7151 log files. Took away the entry->userinfo check from WHOIS
7152 reply sending. The entry->userinfo is now " " if client did not
7153 provide one. I thought this was fixed earlier but something
7154 is wrong still. Let's see if the error still appears.
7156 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Fixed a minor bug in the login when the channel key is
7159 re-generated in the server. It used to generate the key in
7160 wrong order and thus caused problems in the channel traffic.
7162 * Fixed a minor bug in channel key distsribution after
7163 KICK command. The key was not sent to the router even though
7166 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Added silc_ske_process_key_material_data as generic routine
7169 to process any key material as the SILC protocol dictates. The
7170 function is used by the actual SKE library but can be used by
7171 applications as well. This relates to the private message keys
7172 and the channel private keys since they must be processed the
7173 same way the normal SILC session keys. The protocol dictates
7174 this. Affected files: lib/silcske/silcske.[ch].
7176 Added also silc_ske_free_key_material to free the
7177 SilcSKEKeyMaterial structure.
7179 * Defined silc_cipher_set_key function to set the key for
7180 cipher without using the object's method function. The affected
7181 files: lib/silccrypt/silccipher.[ch].
7183 * Implemented silc silc_client_add_private_message_key,
7184 silc_client_add_private_message_key_ske,
7185 silc_client_del_private_message_key,
7186 silc_client_list_private_message_keys and
7187 silc_client_free_private_message_keys functions in the
7190 Added functions silc_client_send_private_message_key to send
7191 the Private Message Key payload and silc_client_private_message_key
7192 to handle incoming Private Message Key payload.
7194 * Added Cipher field to the Private Message Key payload to set
7195 the cipher to be used. If ignored, the default cipher defined
7196 in the SILC protocol (aes-256-cbc) is used.
7198 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7200 * Removed lib/silcclient/ops.h file.
7202 Redefined parts of the SILC Client Library API. Created new
7203 file silcapi.h that deprecates the ops.h file and defines the
7204 published Client Library API. Defined also private message key
7205 API and channel private key API into the file.
7207 This is the file that the application must include from the
7208 SILC Client Library. Other files need not be included by
7209 the application anymore.
7211 * Added new key_agreement client operation callback and also
7212 defined the Key Agreement library API for the application.
7214 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7217 is used by clients to request key negotiation between another
7218 client in the SILC network. If the negotiation is started it
7219 is performed using the SKE protocol. The result of the
7220 negotiation, the secret key material, can be used for example
7221 as private message key.
7223 Implemented the Key Agreement payload into the files
7224 lib/silccore/silauth.[ch].
7226 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Redefined ciphers for the SILC protocol. Added some new ciphers
7229 and defined the key lengths for the algorithms. Changed the
7230 code accordingly. The default key length is now 256 bits.
7232 * Fixed SKE key distribution function silc_ske_process_key_material
7233 when the key length is more than 128 bits. The default key
7234 length in SILC is now 256 bits.
7236 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7237 to indicate unsupported algorithm.
7239 * Renamed rijndael.c to aes.c and all functions as well.
7241 * Fixed a long standing channel key setting bug in client library.
7242 Weird that it has never surfaced before.
7244 * Fixed bug in channel deletion. If the entire channel is removed
7245 then it must also delete the references of the channel entry
7246 from the client's channel list as the client's channel entry and
7247 the channel's client entry share same memory.
7249 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Implemented CONNECT and SHUTDOWN commands in the client.
7253 * Implemented CLOSE command to the client.
7255 * Added the function silc_idlist_find_server_by_name into the
7256 files silcd/idlist.[ch].
7258 Added the function silc_idlist_find_server_by_conn into the
7259 files silcd/idlist.[ch].
7261 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * DIE command was renamed to SHUTDOWN. Updated the both code
7266 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7267 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7269 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7272 * Added function silc_server_create_connection function to create
7273 connection to remote router. My server implementation actually
7274 does not allow router to connect to normal server (it expects
7275 that normal server always initiates the connection to the router)
7276 so the CONNECT command is only good for connecting to another
7279 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7282 or some other client was kicked from the channel.
7284 Implemented the handling of the notify type to both client
7287 Implemented silc_server_send_notify_kicked to send the KICKED
7288 notify. It is used to send it to the server's primary router.
7290 * Implemented the KICK command into server and client.
7292 * Added `query' argument to the silc_idlist_get_client function
7293 to indicate whether to query the client from server or not if
7296 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7297 to indicate that the client is not channel founder.
7301 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7303 * Removed the rng context from SilcPacketContext structure and
7304 changed that the packet routine uses the Global RNG API.
7306 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Added support for quit message that client can "leave" on the
7309 channel when it quits the SILC. It is ditributed inside the
7310 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7312 Added silc_server_free_client_data that will take the
7313 signoff message as argument.
7315 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7317 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Updated parts of the protocol specification to keep it up
7322 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7324 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7325 payloads in one packet.
7327 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7328 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7329 use now the new List flag.
7331 * Also deprecated the following packet types: REPLACE_ID,
7332 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7334 * Added list support for Notify packet in server.
7336 * Added silc_server_send_notify_channel_change to send the
7337 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7338 the silc_server_send_replace_id.
7340 * Added silc_server_send_notify_nick_change to send the
7341 NICK_CHANGE notify type. Deprecates the function
7342 silc_server_send_replace_id.
7344 * Added silc_server_send_notify_join to send the JOIN notify type.
7345 Deprecates the function silc_server_send_new_channel_user.
7347 * Added silc_server_send_notify_leave to send LEAVE notify type.
7348 Deprecates the function silc_server_send_remove_channel_user.
7350 * Added silc_server_send_notify_cmode and
7351 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7352 types. Deprecates the silc_server_send_set_mode function.
7354 * Added SERVER_SIGNOFF notify type to indicate that server has
7355 quit. This means that all clients on the channel from that
7356 server will drop. This can be also used when netsplit happens.
7358 Deprecated REMOVE_ID packet type since it is not needed anymore
7361 Added silc_server_send_notify_server_signoff to send the
7362 SERVER_SIGNOFF notify type. Deprecates the function
7363 silc_server_send_remove_id.
7365 Added also silc_server_send_notify_signoff to send the
7366 SIGNOFF notify type.
7368 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7369 SILC protocol from this day on. Changed the protocol
7370 specification as well.
7372 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7373 notify type. It is used between routers to notify about
7374 topic changes on a channel.
7376 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7379 * Partly updated the protocol specification to comply with the
7380 changes now made. It is still though a bit outdated.
7382 * The JOIN notify type now takes one extra argument <Channel ID>.
7383 The packet used to be destined to the channel but now the
7384 JOIN type may be sent as list thus it is impossible to
7385 destine it to any specific channel. By adding this argument
7386 it is again possible.
7388 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7390 * Added CREDITS file. The CHANGES and CREDITS file will appear
7391 in the distribution as well.
7393 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7396 types in the server's silcd/packet_receive.c.
7398 * Implemented CMODE and CUMODE to work in router environment.
7400 * Fixed minor encoding and decoding buglet from the
7401 lib/silccore/silcmode.c.
7403 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7406 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7408 * Changed all SilcConfigServer* and silc_config_server* to
7409 SilcServerConfig* and silc_server_config*, respectively.
7412 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * Associated the ID (client or server ID) to the Authentication
7415 Payload to avoid any possibility of forging. Updated the
7416 protocol specification and the code accordingly.
7418 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * The RSA key length is now save to the RsaKey context in the
7421 key generation process in lib/silccrypt/rsa.c. The key length
7422 is now used to figure out the maximum size of the block allowed
7423 to be encrypted/signed.
7425 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7426 is equivalent to the silc_mp_mp2bin but does not allocate any
7429 * Changed silc_mp_mp2bin API to take length argument. If it is
7430 non-zero then the buffer is allocated that large. If zero, then
7431 the size is approximated using silc_mp_sizeinbase, which however
7434 * Created Global RNG API which is global RNG that application can
7435 initialize. After initializing, any routine anywhere in the
7436 code (including library) can use RNG without allocating a new
7437 RNG object. This was done to allow this sort of use of the
7438 RNG in code that has no chance to allocate RNG object. All
7439 applications currently allocate this and many routines in the
7440 library use this. Affected file lib/silccrypt/silcrng.[ch].
7442 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7443 it to use the Global RNG API.
7445 * Defined Authentication Payload into protocol specification that
7446 is used during SILC session to authenticate entities. It is
7447 used for example by client to authenticate itself to the server
7448 to obtain server operator privileges.
7450 Implemented this payload into the lib/silccore/silcauth.[ch].
7451 Implemented also routines for public key based authentication
7452 as the new protocol specification dictates.
7454 Moved definitions of different authentication methods from
7455 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7457 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7458 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7459 silc_pkcs_verify_with_hash functions into the file
7460 lib/silccrypt/silcpkcs.[ch].
7462 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * The client entry's userinfo pointer must be always valid.
7465 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7466 will fail since it requires the userinfo. Now, the userinfo
7467 is allocated as "" if actual userinfo does not exist. Actually,
7468 it must exist and it is totally Ok to drop client connections
7469 that does not announce the userinfo. However, we will make
7470 this workaround for now.
7472 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7473 to return the remote port by socket.
7475 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7478 SILC_SERVER_PENDING_EXEC and added an new macro
7479 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7480 data or when error occurs while processing the pending command.
7482 Added new argument `destructor' into silc_server_command_pending
7483 and to the SilcServerCommandPending object. This destructor is
7484 now called after calling the pending callback or if error occurs
7485 immediately. If error occurs the actual pending callback won't
7486 be called at all - only the destructor. The destructor may be
7487 NULL if destructor is not needed.
7489 All this applies for client library code as well. Similar
7490 changes were made there as well for the pending commands.
7492 In the client, the application must now allocate the
7493 SilcClientCommandContext with the silc_client_command_alloc
7496 * Added reference counter to the SilcServerCommandContext. Added
7497 function silc_server_command_alloc and silc_server_command_dup
7500 Same type of functions added to the client library for the same
7503 * Removed the cmd_ident from IDListData away since it is now
7504 global for all connections. It is the command identifier used
7505 in command sending and with pending commands. The affected file
7508 * Added reference counter to the SilcSocketConnection objecet to
7509 indicate the usage count of the object. The object won't be
7510 freed untill the reference counter hits zero. Currently only
7511 server uses this, and client ignores it. The client must be
7512 set to use this too later. The affected files are
7513 lib/silccore/silcsockconn.[ch]. Added also the function
7514 silc_socket_dup to increase the reference counter.
7516 This was mainly added because it is possible that the socket
7517 is removed underneath of pending command or other async
7518 operation. Now it won't be free'd and proper DISCONNECTING
7519 flags, etc. can be set to avoid sending data to connection that
7520 is not valid anymore.
7522 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7523 the connection. After that it sets SILC_SET_DISCONNECTED.
7524 It is, however, possible that the socket data is not still freed.
7525 The silc_server_packet_process now checks that data is not
7526 read or written to connection that is DISCONNECTED. The socket
7527 get's freed when the reference counter hits zero.
7529 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Changed the client operation API: channel_message operation's
7532 `sender' is now the client entry of the sender, not the nickname
7533 and the `channel' is the channel entry, not the channel name.
7535 In the private_message operation the `sender' is now also the
7536 client entry of the sender not the nickname.
7538 Affected file is lib/silcclient/ops.h and all applications
7539 using the client operations.
7541 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7543 * Moved the calling of ops->connect() from connect_to_server_final
7544 into receive_new_id functin since that is the point when the
7545 client is actually allowed to send traffic to network. The
7546 affected file is lib/silcclient/client.c.
7548 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7551 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7552 (if needs broadcasting) instead of broadcasting the packets one
7553 by one which would make a burst in the network traffic.
7555 * Added `broadcast' argument to the functions in silcd/server.[ch]
7556 silc_server_create_new_channel[_with_id] to indicate whether
7557 to send New Channel packet to primary router.
7559 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7561 * Added new function into the silcd/server.[ch] files:
7562 silc_server_create_new_channel_with_id to create new channel with
7563 already existing Channel ID.
7565 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7566 lib/silccore/silcpacket.h. This packet is used t send list of
7567 Set Mode payloads inside one packet. Server uses this to set
7568 the modes for the channels and clients on those channels, that it
7569 announced to the router when it connected to it. The protocol
7570 specification has been updated accordingly.
7572 * The silc_server_new_channel did not handle the packet coming
7573 from normal server as it normally does not send that. However,
7574 when it announces its channels it does send it. Implemented
7575 the support for that.
7577 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7578 into the file lib/silccore/id.h.
7580 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * Fixed memory leaks in the functions silc_idlist_del_client,
7583 silc_idlist_del_channel and silc_idlist_del_server in the file
7584 silcd/idlist.c. All of those leaked like a sieve.
7586 * Fixed some small memory leaks in the client's function
7587 silc_client_notify_by_server.
7589 * Added functions into silcd/server.c: silc_server_announce_clients,
7590 silc_server_announce_channels and silc_server_announce_server.
7591 These functions are used by normal and router server to announce
7592 to its primary router about clients, channels and servers (when
7593 router) that we own. This is done after we've connected to the
7596 These functions effectively implements the following packet types:
7597 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7598 and SILC_PACKET_NEW_ID_LIST.
7600 * Added new functions into the silcd/packet_receive.[ch]:
7601 silc_server_new_id_list, silc_server_new_channel_list and
7602 silc_server_new_channel_user_list to handle the incoming
7603 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7605 * Added support of changing Channel ID in the function
7606 silc_server_replace_id. If the server that announces a channel
7607 to the router already exists in the router (with same name but
7608 with different Channel ID), router is responsible to send
7609 Replace ID packet to the server and force the server to change
7610 the Channel ID to the one router has.
7612 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7613 client that the Channel ID has been changed by the router. The
7614 normal server sends this to the client. Client must start using
7615 the new Channel ID as the channel's ID.
7617 Implemented handling of this new type into lib/silcclient/client.c
7618 into the function silc_client_notify_by_server.
7620 * Added new function silc_idlist_replace_channel_id into the files
7621 silcd/idlist.[ch] to replace the Channel ID.
7623 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Call silc_server_command_identify_check always when processing
7626 the IDENTIFY command in silcd/command.c
7628 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7630 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7631 send keepalive packets. The packet can be sent by clients,
7632 servers and routers.
7634 Added function silc_socket_set_heartbeat into the file
7635 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7636 If not set, the heartbeat is not performed. The actual
7637 heartbeat is implemented in the low level socket connection
7638 library. However, application is responsible of actually
7641 Added silc_server_send_heartbeat to send the actual heartbeat
7642 packet into silcd/packet_send.[ch]. Server now performs
7643 keepalive with all connections.
7645 * Added silc_task_get_first function into lib/silcutil/silctask.c
7646 to return the timeout task with shortest timeout. There was a bug
7647 in task unregistration that caused problems. TODO has been
7648 updated to include that task system must be rewritten.
7650 * The client library will now resolve the client information when
7651 receiving JOIN notify from server for client that we know but
7652 have incomplete information.
7654 * Rewrote parts of silc_server_remove_from_channels and
7655 silc_server_remove_from_one_channel as they did not remove the
7656 channel in some circumstances even though they should've.
7658 * Encryption problem encountered in server:
7660 The LEAVE command used to send the Channel Key packet to the
7661 router immediately after generating it. However, the code
7662 had earlier sent Remove Channel user packet but not immediately,
7663 ie. it was put to queue. The order of packets in the router
7664 was that Channel Key packet was first and Remove Channel User
7665 packet was second, even though they were encrypted in the
7666 reverse order. For this reason, MAC check failed. Now, this
7667 is fixed by not sending the Channel Key packet immediately but
7668 putting it to queue. However, this is more fundamental problem:
7669 packets that are in queue should actually not be encrypted
7670 because packets that are sent immediately gets encrypted
7671 actually with wrong IV (and thus MAC check fails). So, packets
7672 that are in queue should be encrypted when they are sent to
7673 the wire and not when they put to the queue.
7675 However, the problem is that the current system has not been
7676 designed to work that way. Instead, the packet is encrypted
7677 as soon as possible and left to the queue. The queue is then
7678 just purged into wire. There won't be any fixes for this
7679 any time soon. So, the current semantic for packet sending
7682 o If you send packet to remote host and do not force the send
7683 (the packet will be in queue) then all subsequent packets to the
7684 same remote host must also be put to the queue. Only after the
7685 queue has been purged is it safe again to force the packet
7688 o If you send all packets immediately then it safe to send
7689 any of subsequent packets through the queue, however, after
7690 the first packet is put to queue then any subsequent packets
7691 must also be put to the queue.
7693 Follow these rules and everything works fine.
7695 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Added new function silc_server_remove_clients_by_server to
7698 remove all client entries from ID list when the server connection
7699 is lost. In this case it is also important to invalidate all
7700 client entires as they hold the invalid server entry. This
7701 fixes fatal bug when server has lost connection and will reconnect
7704 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7706 * Made some sanity checks to silc_server_daemonise like to check
7707 whether the requested user and group actually exists.
7709 * Added sanity check to SKE's silc_ske_responder_finish to check
7710 that the public and private key actually is valid.
7712 * Invalidate the client's nickname when receiving Replace ID
7713 packet and the Client ID is being replaced. This means that the
7714 server will query the nickname if someone needs it (client)
7717 * Sort the ID Cache in client library when the ID Cache data
7718 has changed (needs sorting).
7720 * Do not allow for SILC client to create several connections to
7721 several servers. The client does not support windows right now
7722 and generating multiple connections causes weird behaviour.
7724 Irssi-silc client does support windows and can handle several
7725 connections without problems, see: www.irssi.org and SILC plugin.
7727 * Fixed some places where client was added to the IDList. The
7728 rule of thumb is following (in order to get everything right):
7729 If the client is directly connected local client then the
7730 `connection' argument must be set and `router' argument must be
7731 NULL to silc_idlist_add_client function. If the client is not
7732 directly connected client then the `router' argument must
7733 bet set and the `connection' argument must be NULL to the
7734 silc_idlist_add_client function.
7736 * The funtion silc_server_packet_send_local_channel actually did
7737 not check whether the client was locally connected or not. It
7738 does that now. Fixed a bug related to LEAVE command.
7740 * Fixed Remove Channel User payload parsing bug in server's
7741 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7743 * The server's silc_server_save_channel_key now checks also the
7744 global ID list for the channel as it might not be in the local
7745 list. Fixed a bug related to LEAVE command.
7747 * Is this the end of the [<unknown>] buglet that has been lurking
7748 around for a long time? A little for loop fix in server's
7749 silc_server_command_whois_parse that is used by both IDENTIFY
7750 and WHOIS command. At least, this was a clear bug and a cause
7751 of one type of [<unknown>] buglet.
7753 * WHOIS and IDENTIFY commands call the function
7754 silc_server_command_[whois/identify]_check function even if
7755 we are not router server.
7757 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7759 * Added --with-gmp configuration option. If set the GMP
7760 is always compiled in the SILC source tree. If not set then
7761 it is checked whether the system has the GMP3 installed. If
7762 it has then the GMP won't be compiled (the system's headers
7763 and library is used), if it doesn't have it then the GMP is
7764 compiled in the SILC source tree.
7766 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7768 * Changed RSA private exponent generation to what PKCS #1
7769 suggests. We try to find the smallest possible d by doing
7770 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7771 not security fix but optimization.
7773 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7775 * Added new config entry [Identity] to fork the server and run
7776 it as specific user and group. A patch from Bostik.
7778 * Imported Dotconf configuration library into lib/dotconf.
7779 This will be used to create the SILC configuration files later.
7780 It will appear in the distsribution after this commit.
7782 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * A big code auditing weekend happening. Auditing code for
7785 obvious mistakes, bugs and errors. Also, removing any code
7788 Removed files for being obsolete:
7790 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7791 inline in the file lib/silcutil/silcbuffer.h)
7793 o lib/silcutil/silcbufutil.c (the header has inline versions)
7795 Changed code to fix possible error conditions:
7797 o The buffer formatting routines now check that the destination
7798 buffer really has enough space to add the data. This applies for
7799 both buffer formatting and unformatting
7800 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7801 unformatting was changed to accomodate following rules:
7802 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7803 sent to the function while XXX_*STRING will not allocate or copy
7804 the data into the buffer. Instead it sets the pointer from the
7805 buffer into the pointer sent as argument (XXX_*STRING used to
7806 require that the pointer must be allocated already). This change
7807 makes this whole thing a bit more consistent and more optimized
7808 (note that the data returned in the unformatting with XXX_*STRING
7809 must not be freed now). The routines return now -1 on error.
7811 o Tried to find all code that use buffer_format and buffer_unformat
7812 and added return value checking to prevent formatting and
7813 especially unformatting errors and possible subsequent fatal
7816 o Changed ske->x and ske->KEY to mallocated pointers in
7817 lib/silcske/silcske.h. Fixed possible data and memory leak.
7819 o Added return value checking to all *_parse* functions. Fixed
7820 many memory leaks as well.
7822 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7823 so that buffer overflows would not happen. All code now also
7824 checks the return value as it can fail.
7826 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7828 * Added reconnection support to server if the normal server looses
7829 its connection to the router (for example if router is rebooted).
7830 The server performs normal reconnection strategy implemented
7831 to the server. Affected file silcd/server.c.
7833 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Added new packet type SILC_PACKET_SET_MODE that is used to
7836 distribute the information about changed modes (for clients,
7837 channels and clients channel modes) to all routers in the
7838 network. Updated the protocol specification accordingly.
7840 Added functions into silcd/packet_send.c and
7841 silcd/packet_receive.c: silc_server_send_set_mode,
7842 silc_server_set_mode.
7844 Added new files silcmode.[ch] into lib/silccore that implements
7845 the encoding and decoding of Set Mode Payload. Added new type
7846 SilcSetModePayload. Moved the definitions of different modes
7847 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7849 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * Oops, a little mistake in server's connection authentication
7852 protocol. The protocol is not ended with FAILURE but with
7853 SUCCESS if the authentication is Ok. :) Affected file is
7856 * Implemented NICK_CHANGE notify handling in server in the file
7857 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7858 the local clients on the channel. After the changing nickname
7859 in router environment snhould work and the [<unknown>] nickname
7860 should appear no more.
7862 The silc_server_replace_id function that receives the Replace ID
7863 payload now sends the NICK_CHANGE notify type also in the file
7864 silcd/packet_receive.c
7866 * Changed WHOIS and IDENTIFY command to support the maximum amount
7867 of arguments defined in protocol specs (3328 arguments). This
7868 fixed a bug that caused problems when there were more than three
7871 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7873 * Added extra parameter, command identifier, to the
7874 silc_client_send_command so that explicit command identifier
7877 Changed that ID list routines uses specific command identifier
7878 when sending WHOIS/IDENTIFY requests to the server so that they
7879 can be identified when the reply comes back.
7881 Affected files lib/silcclient/command.[ch],
7882 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7884 * Added `sender' argument to silc_server_packet_send_to_channel
7885 to indicaet the sender who originally sent the packet to us
7886 that we are now re-sending. Ignored if NULL. Affected file
7887 silcd/packet_send.[ch].
7889 * Added some server statistics support in silcd/server_internal.h
7890 SilcServerStatistics structure and around the server code. Also
7891 send some nice statistics information when client is connecting
7894 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7896 * Fixed channel ID decoding in server's JOIN command reply in
7897 silcd/command_reply.c
7899 * Fixed braodcasting of replace ID payload to not to send it if
7900 we are standalone server in silcd/packet_receive.c.
7902 * Fixed all channel message sending routines to not to send
7903 packets to clients that has router set, since they are routed
7904 separately in the same function earlier. Affects file
7905 silcd/packet_send.c and all channel packet sending functions.
7907 * In USERS reply, res_argv[i] are not allocated, the table
7908 is allocated. Thus changed that free the table, not its
7911 * In server's whois_check and identify_check if the client is
7912 locally connected do not send any WHOIS commands - they are not
7915 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7917 * Fixed some minor bugs in client when sending WHOIS command. The
7918 arguments was in wrong order.
7920 * Removed statis function add_to_channel from server in
7921 silcd/command.c that was previously used with the joining but
7924 * Tested USERS command in router environment successfully with two
7925 routers, two servers and two clients.
7927 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Reorganized the USERS command and command reply in client library
7930 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7931 When the command is given by user we register a pending command
7932 callback that will reprocess the command after the reply has been
7933 received from the server. When reprocessing the packet we then
7934 display the information. Thus, the USERS information is displayed
7935 now in the command callback instead of in the command reply
7936 callback. The processing of the command is same as previously
7937 when server has sent the command reply in the JOINing process.
7939 * Added to USERS command in silcd/command_reply.c to join the client,
7940 we didn't use to know about, to the channel after we've created
7941 a client entry for it. Also, for clienet we did know already still
7942 check whether it is on the channel or not and add it if not.
7944 * Removed silc_server_command_join_notify as the function and its
7947 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7949 * Changed the client's pending command handling to the same as the
7950 server's pending command handling. It is also now possible to
7951 execute command reply functions from other command reply
7952 function as the function callbacks for commands and command
7953 replies are one and same. The pending commands are not static
7954 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7955 in client connection context. Thus, pending commands are server
7956 connection specific as it is convenient.
7958 Changed the function silc_client_command_pending and
7959 silc_client_command_pending_del and added new function
7960 silc_client_command_pending_check. Removed the
7961 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7964 * Added cmd_ident, current command identifier, to the client
7965 connection context in lib/silcclient/client.h to keep track on
7966 command identifiers used in command sending. Client's command reply
7967 function handling now supports the mandatory command identifiers.
7969 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7970 funtions in client to fully support pending command callbacks.
7972 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7973 as one of the arguments to the application in the command reply
7976 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7977 before first releasing SILC but came back. Now it is removed again
7978 and should come back nomore. The FORWARDED flag was used only
7979 by the JOINing procedure by forwarding the command packet to router.
7980 Now, the JOINing procedure has been changed to more generic (due
7981 to various router environment issues) and FORWARDED is not needed
7982 anymore for anything. The protocol specification is yet to be
7985 Now, removed silc_server_packet_forward from server and the flag
7986 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7988 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7990 * Renamed NAMES command to USERS command. The NAMES was named that
7991 due to historical reasons. Now it is renamed. Also, rewrote
7992 parts of the USERS command. The nickname list is not sent anymore
7993 by the server. Only Client ID and mode lists are sent in the USERS
7994 command. Changed this also to the protocol specification.
7996 The client now resolves the names and stuff after it receives
7997 the USERS list from the server when joining to the channel.
7999 * WHOIS and IDENTIFY commands has been changed to support multiple
8000 Client ID's per command. One can now search for multiple users
8001 in the network by sending only one WHOIS or IDENTIFY command.
8002 Changed the code and the protocol specifications.
8004 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8005 uses silc_server_command_whois_parse to parse the request. */
8007 * If normal server, do not parse the WHOIS and IDENTIFY requests
8008 before sending it to the router. Saves some time.
8010 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8012 * Fixed JOIN command on client library. Wrong number of arguments
8013 used to crash the client.
8015 * Added silc_server_channel_has_global function to check whether
8016 channel has global users or not.
8018 * Added silc_server_channel_has_local function to check whether channel
8019 has locally connected clients on the channel.
8021 * The silc_server_remove_from_one_channel now checks whether the
8022 channel has global users or not after given client was removed from
8023 the channel. It also checks whether the channel has local clients
8024 on the channel anymore. If it does not have then the channel entry
8025 is removed as it is not needed anymore.
8027 * The silc_server_notify now checks on JOIN notify whether the joining
8028 client is one of locally connected or global. If it is global then
8029 the channel has now global users on the channel and that is marked
8030 to the channel entry. Also, it now saves the global client to
8031 global list who is joining and JOINs it to the channel. This is
8032 for normal server, that is.
8034 Changed silc_server_send_notify_on_channel,
8035 silc_server_packet_relay_to_channel and
8036 silc_server_packet_send_to_channel check if we are normal server
8037 and client has router set (ie. global client) do not send the
8038 message to that client, as it is already routed to our router.
8040 * Implemented LEAVE notify type handling in silc_server_notify
8043 * Tested LEAVE command in router environment successfully. Tested
8044 with two routers, two servers and two clients.
8048 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8050 * Implemented SIGNOFF notify type handling in silc_server_notify
8053 * silc_server_remove_id now removes the client entry from all channels
8054 it has joined and thusly sends SIGNOFF notify type.
8056 * Rewrote the NAMES list generation in server by removing two excess
8057 loops. The lists are created now inside one loop.
8059 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8061 * silc_server_remove_channel_user checks now also global list
8062 for channel and client.
8064 * silc_server_new_channel_user checks now both local and global
8065 list for channel and client. Fixed a bug in client id decoding.
8066 Used to decode wrong buffer.
8068 * silc_server_channel_message checks now both local and global
8069 list for channel entry.
8071 * Tested channel joining (hence JOIN) in router environment
8072 successfully. Tested with two routers, two servers and two
8075 * Tested channel message sending in router environment successfully.
8077 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8079 * Added silc_server_save_channel_key into server.[ch] to save the
8080 received channel key in Channel Key payload processing. It is
8081 also used in JOIN command reply handling.
8083 Equivalent function silc_client_save_channel_key added into
8084 client.[ch] into client library.
8086 * Changed JOIN command reply to send information whether the channel
8087 was created or not (is existing already) and the channel key
8088 payload. Changed protocol specs accordingly.
8090 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8091 the request was sent by ID and not by nickname. Crashed on
8094 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8097 now correctly save the received data.
8099 * silc_server_free_sock_user_data now notifies routers in the
8100 network about entities leaving the network.
8102 At the same time implemented functions silc_server_remove_id
8103 and silc_server_send_remove_id to receive and send REMOVE_ID
8104 packets. The packet is used to notify routers in the network
8105 about leaving entities. The ID removed will become invalid in
8108 * Added function silc_idlist_del_server into server. Removes and
8109 free's server entry from ID list.
8111 * silc_server_private_message function now checks, if we are router,
8112 that the destination ID really is valid ID, naturally.
8114 * In router when NEW_ID packet is received (for new client) the
8115 hash of the Client ID is saved in the ID Cache but the
8116 client->nickname is set to NULL, instead of putting the hash
8119 IDENTIFY command now also checks that client->nickname must be
8120 valid. If it is not if will request the data from the server who
8121 owns the client. Added new function
8122 silc_server_command_identify_check.
8124 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8125 to set the command to already allocated Command Payload.
8127 * Tested private message sending in router environment with two
8128 routers, two servers and two clients. Fixed minor bugs and now
8131 * Fixed segfault from client's NAMES command. Used to crash if
8134 * Forwarded packets must not be routed even if it is not destined
8135 to the receiver. Changed server code comply with this.
8137 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8139 * Added `require_reverse_mapping' boolean value to ServerParams
8140 structure. If TRUE (not default) the server will require that
8141 the connecting host has fully qualified domain name.
8143 If the reverse mapping is not required and hostname could not be
8144 found the IP address is used as hostname.
8146 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8148 * Implemented version string checking to both client and server.
8149 The check is incomplete currently due to the abnormal version
8150 strings used in development version of SILC.
8152 * Changed all command functions in server to use the new
8155 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8157 * Changed char *data to unsigned char *data in ID Cache system to
8158 support binary data as ID Cache data. Changed code to support
8159 binary data in lib/silccore/idcache.c.
8161 * Renamed silc_server_packet_relay_command_reply to
8162 silc_server_command_reply as it is normal packet receiving
8163 function. Rewrote the function to accept command replys for
8164 servers and not only for clients.
8166 * Mark remote router always as registered server if we are connecting
8167 to it. Otherwise, commands sent by the router to us are ignored.
8169 * All ID List find routines now returns the ID Cache Entry pointer
8170 as well if requested.
8172 * WHOIS command works now in router environment, tested with two
8173 routers, two servers and two clients.
8175 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8176 in router environment (as it is almost equivalent to WHOIS) but
8177 hasn't been tested thoroughly. Added new functions:
8179 silc_server_command_identify_parse
8180 silc_server_command_identify_send_reply
8181 silc_server_command_identify_from_client
8182 silc_server_command_identify_from_server
8184 * Disabled route cache adding because adding two different ID's with
8185 same IP replaces the old cache entry thus giving wrong route.
8186 The entry->router->connection is always the fastest route anyway
8187 so route cache may not be needed. Of course, new routes maybe
8188 established after receiving the ID when the entry->router->connection
8189 might not be anymore the most optimal.
8191 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8193 * Add route cache for received ID for fast routing.
8195 * Added silc_server_packet_route to route received packet on router
8196 that is not destined to us.
8198 * Renamed silc_server_get_route to silc_server_route_get.
8200 * Added id_string and id_string_len fields into SilcServer to
8201 include encoded ServerID for fast comparing without excess
8202 encoding of the ID's.
8204 * Cleaned up WHOIS command on server side. Added following static
8207 silc_server_command_whois_parse
8208 silc_server_command_whois_check
8209 silc_server_command_whois_send_reply
8210 silc_server_command_whois_from_client
8211 silc_server_command_whois_from_server
8213 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8214 arguments in command replies. All command functions should be
8215 updated to use this macro.
8217 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8219 * Minor typo fixes on command reply handling on server.
8221 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Added silc_server_command_add_to_channel internal routine to add
8224 the client to the channel after router has created the channel and
8225 sent command reply to the server.
8227 * Added generic silc_server_send_command to send any command from
8230 * Use static buffer with ID rendering instead of duplicating data.
8232 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Fixed a channel user mode bug when joining to a channel server gave
8235 everybody channel founder rights, oops.
8237 * We mark ourselves as the router of the incoming server connection
8238 if we are router ourselves. This way we can check in some packet
8239 sending functions whether it is locally connected server. For
8240 incoming router connections we put NULL.
8242 * For router sending packets locally means now always sending the
8243 packet cell wide; to local clients and local servers. For normal
8244 server sending packet locally means sending it to only local
8247 * Fixed the JOIN command to really work in router environment. If the
8248 channel is created it is always created by the router. Router is
8249 also responsible of making the initial joining to the channel,
8250 sending JOIN notify to the sending server and distributing
8251 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8252 does not exist server doesn't do anything else but forward the
8253 command to the router which performs everything.
8255 * Added silc_server_send_channel_key function to send the Channel Key
8258 * Added silc_server_create_channel_key to create new channel key. The
8259 channel key is now re-generated everytime someone joins or leaves
8260 a channel, as protocol dictates. Note: channel->key_len is the
8263 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8265 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8266 packet_receive.[ch] to separate packet sending and receiving
8267 routines. The server.[ch] now includes everything else including
8268 actual packet processing (writing and reading data) and other
8271 Renamed silc_server_private_message_send_internal to
8272 silc_server_send_private_message. The routine is still though
8273 used only to relay private messages as server does not send
8274 private messages itself.
8276 Renamed silc_server_new_channel to silc_server_create_new_channel
8277 and added new function sicl_server_new_channel that handles the
8278 incoming New Channel packet. Added also new sending function
8279 silc_server_send_new_channel to send New Channel Payload.
8281 * Added new function silc_server_notify to process incoming notify
8282 packet to the server/router. Server may then relay the notify
8283 to clients if needed.
8285 * Added new function silc_server_new_channel_user to process incoming
8286 New Channel User packet. Router will redistribute the packet and
8287 send JOIN notify to its local clients and locally connected servers
8288 if needed. Normal server will send JOIN notify to its local client
8289 on same channel when received this packet. Added also corresponding
8290 sending function silc_server_send_new_channel_user to sent the
8293 * Added boolean route argument to send_notif_to_channel and
8294 packet_send_to_channel functions to attempt to route the packet
8295 if it is TRUE and send only locally if it is FALSE.
8297 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8299 * silc_server_replace_id now broadcasts the received replace ID
8300 packet if it is not broadcast packet already. The router must
8301 broadcast to inform other routers about changed ID.
8303 * Added backpointer to server's router into SilcServer context in
8304 silcd/server_internal.h.
8306 * Fixed silc_server_packet_broadcast to send correct broadcast
8309 * The channel key is now distributed to the local client as soon
8310 as it is received from the router (in router environment) so that
8311 no other packet may be sent for the channel until client has
8314 * silc_server_remove_channel_user now broadcasts the received
8315 Remove Channel User packet if it is not broadcast packet already.
8316 The router must broadcast to inform other routers about removed
8319 * Added users field into SilcPacketContext that is a reference count
8320 of the context. One can increase the reference count by calling
8321 silc_packet_context_dup which is now changed to just increase the
8322 reference count instead of duplicating the data. The reference
8323 count is decresed by calling silc_packet_context_free that will
8324 free the data after the reference count hits zero.
8326 For now on the packet context and everything allocated into it
8327 (including the raw packet from network) must be freed by calling
8328 the new silc_packet_context_free function. Added also new function
8329 silc_packet_context_alloc that must be used now to allocate the
8330 context. This also means that if a routine is asynchronous from
8331 silc_[client/server]_packet_parse_type the packet context must
8332 be duplicated by calling silc_packet_context_dup. Otherwise it
8333 gets free'd after silc_[client/server]_packet_parse_type returns.
8334 Also, one must remember that if packet is duplicated then its
8335 reference count must be decresed by calling the free function as
8336 many times as it was duplicated.
8338 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8339 from both client and server.
8341 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8343 * Made joining to a channel working in router environment.
8345 * Cleaned up JOIN command on server side and create function
8346 silc_server_command_join_channel internal routine to make the
8349 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8351 * Changed silc_command_pending list to SilcDList. Also, added
8352 `ident' field to SilcServerCommandPending structure to identify
8353 the reply and to call correct callback.
8355 Added silc_server_command_pending_check function to replace the
8356 corresnponding macro. The silc_command_pending list is not
8359 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8360 to set identifier to previously allocated Command Payload. It
8361 is used to set identifier for command when resending Command
8364 * Added silc_command_payload_encode_payload to encode Command
8365 Payload buffer from SilcCommandPayload structure.
8367 * Added silc_argument_payload_encode_payload to encode Argument
8368 payload buffer from SilcArgumentPayload structure.
8370 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8372 * Changed WHOIS command to support router connection on server side.
8373 The whois request is always sent to router unless the server is
8374 standalone server. After server has received the reply from the
8375 router will it send the reply to the client.
8377 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8378 broadcast received broadcast packet. The function is used only
8379 by router. The broadcast packet is always sent to the router's
8382 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8383 render given ID to printable string, for log files for example.
8385 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8387 * Made basic router to router connections working. At least they
8388 can now connect to each other but nothing really works the way
8389 they are supposed - yet.
8391 * Added new initiator token to RouterConnection configuration
8392 file in silcd/serverconfig.[ch]. It is used to tell whether we
8393 are the initiator to the remote router or whether we'll expect
8394 the other end to connect.
8396 * Moved registering of listener task to silc_server_init, hence
8397 the server starts listenning as soon as it is run, even if it
8398 does not have connections to other routers. Let's see how well
8401 * Changed default connection retry timeouts for more suitable in
8404 * Removed cipher and such arguments from silc_idlist_add_client
8405 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8406 Added new function silc_idlist_add_data to add the keys and stuff
8409 * Added SilcIDListData structure and added it to SilcClientEntry
8410 and SilcServerEntry as their first field in the structure. This
8411 way we can explicitly cast the ID entries to the SilcIDListData
8412 structure and get common data for the entries. In past, we had
8413 to first check what type of connection it is and then cast it to
8414 correct ID entry type. Now, we can directly cast the opaque
8415 pointer to the SilcIDListData (no matter what ID entry it actually
8416 is) and get the data needed.
8418 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8420 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8421 in some circumstances even if threre were timeout tasks, though not
8422 IO tasks, but tasks anyway. Now fixed.
8424 * Defined SilcServerConnection structure to hold connection specific
8425 stuff about directly connected servers and routers. The definition
8426 is currently in silcd/server_internal.h. I thought about having
8427 a bit more important role fro this struct but for now it is used
8428 only when connecting to other server (or router actually).
8430 * Added connecting retry support in server when connecting to
8431 router(s). The retry feature implement exponential backoff
8432 algorithm. Also, added SilcServerParams structure to hold default
8433 parameters for server. For now, it include these retry settings
8434 and are hard coded. After server is moded to be as Silc Server
8435 Library this structure will be more important.
8437 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8439 * Changed client librarys channel->clients table to SilcList and
8440 changed code accordingly.
8442 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8444 * Changed client's channel table to SilcList and changed code
8445 accordingly. Also changed SilcChannelClientEntry to include back-
8446 pointer to the channel so that client entry can use that structure
8447 as list as well and we have fast cross-reference to the channel.
8448 This change dramatically decreased the complexity of channel
8449 handling with client entry and vice versa (removed one extra
8450 loop when searching for channel entry from many functions).
8452 * Changed server->sim from table to SilcDList and changed code
8455 * NAMES command can now be used from user interface. It will show
8456 the user list on the channel, neatly.
8458 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8459 Code now saves realname of the user if it becomes available.
8461 * Renamed configure.in to configure.in.pre and made ./prepare
8462 script to automatically add correct version string to
8463 configure.in which it creates from configure.in.pre.
8465 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8467 * NAMES command reply now shows users mode with the nickname when
8470 * Moved silc_client_ch[u]mode[_char] functions from
8471 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8472 place sucks, they are utility functions and should be in some
8475 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8477 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8480 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8484 * Added TRQ (efficient deque and list library) into lib/trq. This is
8485 a very good list library that is currently used in the SILC. Defined
8486 SilcList API over the library because I didn't like the API very
8487 much. See lib/trq/silclist.h for the API and examples of how to
8488 use the API. Fixed various places in the code to use the new
8489 SilcList API. The SilcList is meant for lists that has a structure
8490 already defined as a list. It is not suitable to add just some
8491 context to the list (in TRQ, the context is the list actually).
8493 So, I defined SilcDList that can be used for the purpose where
8494 predefined list structure does not exit. This can be used as
8495 such list. Now some context just can be added to the SilcDList.
8496 Currently this list is not used in the SILC just yet, though there
8497 are a lot places where this can replace dynamically allocated
8498 tables and I will fix these places, later, to use SilcDList.
8499 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8500 and use TRQ internally).
8502 Also fixed some annoying warning messages that the original TRQ
8503 code generated. Also minor changes to TRQ's Makefile.in.
8505 * Added support for querying by Client ID to both WHOIS and
8506 IDENTIFY commands into server, as required by the protocol.
8508 * Removed method function pointers from SilcBuffer structure. They
8509 weren't used to anything and just increased the context size for
8510 no good reason. This change also made silc_buffer_alloc and
8511 silc_buffer_free functions inline functions.
8513 * Disabled command flooding detection support until it's fixed so
8514 that it accepts commands in but does not execute them more than once
8517 * Added silc_net_localhost(), to return local hostname, into
8518 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8519 that must be initialized before calling silc_client_init.
8521 * Added new function: silc_server_send_notify_on_channels to send
8522 notify messages to all channels client has joined. It is assured
8523 that the message is sent only once per client.
8525 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8526 lib/silcutil/silcutil.[ch] as silc_format function. The new
8527 function is generic and is used by server as well, not only by
8528 the logging routines.
8530 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8531 the provided version string was not acceptable. Added new function:
8532 silc_ske_check_version into lib/silcske/silcske.h. The function
8533 must be implemented by the application (client or server) and it
8534 does not reside in the SKE library. The function checks the version
8535 string remote end sent.
8537 * Added back pointers (to opaque context and to SilcSocketConnection)
8538 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8540 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8541 duplicate packet context structure.
8543 * Changed `notify' client operation to send same arguments as client
8544 receives from server except for ID's. ID's are mapped to correct
8545 ID entry and that is returned. Also, if channel entry is not sent
8546 by server but the notify is for channel the channel entry is sent
8547 to application (otherwise application doesn't know that it is for
8548 channel (library gets it from packet's Destination ID)).
8550 * Added silc_client_remove_from_channels into client library to
8551 remove a client from all channels it has joined to. Used when
8552 received SIGNOFF notify from server. Added also new function
8553 silc_client_replace_from_channels to replace old ID entry with
8554 new ID entry on all channels. Used when received NICK_CHANGE
8557 * Fixed ID Cache list handling in silc_idlist_get_client in
8558 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8559 to get (or query) client by ID.
8561 * Updated TODO list.
8563 * Added connection authentication status message defined by the
8564 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8565 support for these into the code in client and server side.
8567 * Added generic function silc_client_send_command to send any command
8568 with variable argument list. Application should use this function
8569 to send commands if the command functions provided by the library
8570 does not suite for the application's user interface needs.
8572 * Added new `failure' client operation. Application is notified about
8573 received failure packet if client is executing a protocol. In this
8574 case the protocol's execution has failed.
8576 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8577 is required by the protocol.
8579 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8580 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8583 * Added status flag to SilcSKE object to indicate realtime status
8584 of the SKE protocol.
8586 * Application receives now exactly same command reply arguments as
8587 the library receives from server. However, if ID is received the
8588 corresponding ID entry is returned to the application (eg. Client
8589 ID is mapped to correct SilcClientEntry entry and that is returned).
8590 Changed command_reply client operation due to this change.
8592 * Changed all ID's in commands and in command replys as ID Payloads.
8593 Change affected both client and server side codes.
8595 All ID's sent in SILC network (with execption of ID's in SILC
8596 Packet header) are sent in ID Payload to support variable length
8599 * Server now notifies nick changes and notifies all clients on
8600 the channels about the new nickname (about the new Client ID,
8603 * Implemented CMODE command to change channel modes. Supports all
8604 channel modes defined by the protocol specs except ban and invite
8605 lists. (Also, private channel key mode is supported but support for
8606 setting private channel key in client is missing, thus, this mode
8607 has no effect on client side (except that server requires that the
8608 client uses private channel key and normal channel traffic does not
8611 Also, invite mode works per se, but INVITE command does not work
8612 yet correctly, so you can set channel as invite only channel but
8613 inviting clients to the channel does not work (it is yet to be
8614 thought what's the best way to do it).
8616 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8617 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8618 Implemented CUMODE command to change user's mode on the channel.
8619 Supports all modes defined by the protocol specs.
8621 * Added NAMES command reply to return users modes on the channel.
8623 * Removed unnecessary and slow ciphers from lib/silccrypt.
8625 * Set SO_KEEPALIVE option to connection sockets by default.
8627 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8629 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8630 redefined the Notify Payload into protocol specs.
8632 * Added silc_id_payload_parse_id to get ID directly from raw
8635 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8637 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8638 accept searching by Client ID as well.
8640 * Added support for LEAVE and SIGNOFF notify types in client library.
8642 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8643 to parse ID Payload from raw data.
8645 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8647 * Added flags parameter into silc_ske_assemble_security_properties
8648 function in lib/silcske/silcske.[ch].
8650 * Changed notify client operation to fit better for notify messages
8651 sent by server. The notify payload received from server is now
8652 passed to the application (after parsing it to SilcNotifyPayload).
8653 It is application's responsibility to retrieve the arguments
8654 from the payload and show the message the way it wants. The message
8655 sent by server is implementation specific.
8657 * Changed public keys to comply with the protocol specification.
8658 Old public keys are not supported anymore and are not compatible.
8660 * Removed nickname from Channel Payload as the latest draft removed
8661 it. The client must resolve the nickname from the NAMES command
8662 reply received when it joined the channel.
8664 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8666 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8668 * Fixed some errors in protocol specification drafts.
8670 * Created lib/silccore/silcnotify.c to implement Notify Payload
8671 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8672 generic payloads described by protocol specifications. The file
8673 includes implementations for ID Payload and Argument Payload.
8675 * Changed Command Payload implementation to use the new Argument
8676 Payload. Changed command_xxxx_payload to command_payload_xxxx
8677 to comply with SILC coding conventions.
8679 * Added suppport for Argument Payload handling in Notify Payload
8680 implementation as protocol requires it. Added the new support
8681 into server and client lib as well.
8683 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8685 * Added support for multiple nicknames on same channel. [n] is
8686 added locally to the nickname if there are more than one same
8687 nicknames on the channel.
8689 * Server now sends all nicknames that matched WHOIS request.
8690 Client also shows the list received from server.
8692 * Added TOPIC command to client side. User can now set and show
8693 current topic on channel.
8695 * Added MOTD command to client and server. Also, server sends the
8696 motd when client connects to the server.
8698 * Changed version strings to comply ISO 8601.
8700 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8702 * Fixed protocol error handling in client library. It should now
8703 cope even if the SKE fails for some reason.
8705 * Made new protocol specification drafts for submitting to IETF.
8707 * Implemented TOPIC command to server in silcd/command.c.
8709 * Added two new notify types into lib/silccore/silcnotify.h:
8710 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8711 notify nickname change and topic setting/change on a channel.
8713 * API change of command_reply operation in client library. The
8714 application gets now the status type received from server as well.
8716 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8718 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8720 * Cras fixed and optimized the packet handling even further and
8721 it should work now. Minor change to the prototype of function
8722 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8724 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8726 * Added new function into lib/silcutil/silcschedule.[ch]:
8727 silc_schedule_with_fd to select() a specified fd. The function
8728 returns after timeout expires or data arrives or goes. The
8729 function is used by packet routines to wait that all data is
8730 received from network.
8732 * Fixed data reading from network in lib/silccore/silcpacket.c.
8733 The code now assures that all data is read from the fd and then
8734 continues packet processing. This was a bug fix since the code
8735 used to drop some data in some circumstances.
8737 * Added new function into lib/silcclient/client.[ch]:
8738 silc_client_start_key_exchange to start key exchange after
8739 connection has been established to server. The code internally
8740 now uses this funtion but its main purpose was to provide it
8741 for applications that perform their own connecting. After
8742 application has created a connection it merely calls this
8743 function to start the key exchange between client and server.
8744 The library takes care of everything else after that.
8746 Updated also lib/silcclient/README to explain the usage of
8749 * Do not send to application information that connection has
8750 been established. Application gets notified it by connect
8753 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8755 * Applied cras's patch to add silc_schedule_one function. The
8756 function runs scheduler once and returns.
8758 * Fixed the scheduler after cras messed it up. The timeout
8759 handling works now as it's supposed to work.
8761 * Added into lib/silccore/ silcnotify.h to include notify
8762 message types support. Changed silc_server_send_notify*
8763 functions, in server.[ch], to support those new notify types.
8764 Added the support for the notify types into client library,
8765 as well. Added new notify client operation into ops.h in
8768 * Changed silc_server_packet_send_to_channel to send normal
8769 packets instead of just channel message packets. The function
8770 is now used to send the notify packets to channels. It is not
8771 used to send channel message packets anymore, as server never
8774 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8775 va_arg()s as it seems to require it nowadays. I guess, if SILC
8776 is compiled with older va_arg() the new code should work anyway.
8778 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8780 * Splitted core library. Core library (lib/silccore) includes
8781 now only SILC protocol specific core (and common) components.
8782 Created new utility library (lib/silcutil) that includes more
8783 generic purpose stuff. The stuff for util library was taken
8784 from the old core library. This was minor and easy split.
8786 * Created SILC Client Library (lib/silcclient) that includes
8787 implementation of the SILC client without user interface. This
8788 was major move from silc/ directory. The code has been changed
8789 so that it is transparent towards the user interface. The
8790 silc/ directory includes now the same user interface as before
8791 and it uses the new client library. Read lib/silcclient/README.
8792 Basicly, the client library performs everything else related
8793 to SILC except user interface handling. Also, configuration
8794 files are considered to be part of user interface and library
8795 does not handle them.
8797 This change also changed a lot of structures, function naming etc.
8798 Most important change was that SilcClientWindow object was
8799 renamed to SilcClientConnection in the client library. Created
8800 also new file lib/silcclient/ops.h. Also added new files
8801 silc/local_command.[ch] and silc/client_ops.[ch].
8803 All these changes were made to make it easier for user interface
8804 designers to create what ever user interface for the SILC client
8807 It is also expected that the server will be moved to lib
8808 directory as well and SILC Server Library will be created;
8809 sometimes in the future.
8811 * Removed Local commands from lib/silccore/silccommand.h as
8812 they are application specific and new client library does not
8813 handle any of those anymore.
8815 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8816 old client implementation in silc/.
8818 * Added support for callback functions in SILC_LOG_* macros.
8819 Application can now set its own callbacks that will be called
8820 instead of using the default functions that will always print
8821 the debug messages to stderr (or stdout). Also, debugging can
8822 now be disabled by setting silc_debug to FALSE and re-enabled by
8823 setting it to TRUE. Note, that logging will still work even
8824 if debugging is disabled.
8826 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8827 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8828 silc_log_reset_debug_callbacks.
8830 * To enable debugging in silc client one must give now -d
8831 option on command line.
8833 * Changed silc_schedule_init to automatically allocate task queues
8834 if they are not allocated before calling it.
8836 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8838 * Added GMP 3.1 into math library.
8840 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8842 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8843 a channel in SILC network. The packet is used by servers and
8844 routers to notify other routers that user has left a channel.
8845 This little feature was missing until now. Added the feature
8846 to protocol specification as well.
8848 Added functions: silc_server_send_remove_channel_user and
8849 silc_server_remove_channel_user into server.[ch].
8851 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8852 lib/silccore/silcpacket.h. However, they are not implemented
8855 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8857 * Fixed joining to a channel and sending channel messages
8858 between server and router. The channel message sending should
8859 now work inside a cell.
8861 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8863 * Fixed the private message sending between server and router.
8864 The private message sending should now work inside a cell.
8866 * Added silc_server_replace_id into server.[ch] to replace
8867 existing ID in the SILC network.
8869 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8870 and silc_idlist_replace_server_id into idlist.[ch] in server.
8872 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8874 * Fixed the server to server connections. Server can again now
8875 connect to router. Router to router connections probably does
8878 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8880 * Added dynamic protocol registering support. Now protocols can
8881 registered and unregistered on the fly. Patch by cras.
8883 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8885 * Added lib/contrib directory to hold routines that some platforms
8886 don't have but are needed by SILC.
8888 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8889 into lin/contrib to provide getopt() and getopt_long() for
8890 those who don't have it.
8892 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8894 * Added AWAY command to client. When away message is set and
8895 client receives a private message packet the client automatically
8896 replies to the sender with the away message.
8898 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8899 bug seemed to be the cause of recent problems when compiling
8902 * Added version detection support to SKE protocol specification
8903 and added the new changes to the SKE implementation as well.
8904 There were other minor changes in the SKE protocol as well.
8906 Many changes in lib/silcske/silcske.[ch] and in
8907 lib/silcske/payload.[ch].
8909 * Added ^U functionality, clear input line. Patch from cras.
8911 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8913 * Mainly small bugfixes on core library. Fixed some debugging
8914 logging and buffer overflow in silclog.c.
8916 * Updated config.sub and config.guess on the distribution tree.
8918 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8920 * Added command lagging support in server. Client may execute
8921 commands now only once in two seconds.
8923 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8925 * Optimized packet reception. MAC computation and checking is now
8926 also more optimized. A lot previously duplicated code is now
8927 used as generic by both client and server.
8929 * Fixed key pair generation in clientutil.c
8931 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8933 * Added into lib/silccore/silcbufutil.[ch] new function;
8934 silc_buffer_realloc.
8936 * Moved generic packet sending/encryption functions to
8937 lib/silccore/silcpacket.[ch] from client and server. Some
8938 rewriting of the functions.
8940 * Moved all generic packet reception/decryption functions to
8941 lib/silccore/silcpacket.[ch] from client and server. The
8942 packet processing is now much cleaner in both client and server.
8943 These were major changes in both client and server.
8945 * Created many common functions in server to do packet sending.
8946 Previously code were duplicated a lot, this has been removed
8949 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8951 * Rewrote major parts of the ID cache system. Don't know
8952 whether it is better now or not but at least the API is more
8955 * Major rewrite on ID cache stuff on client because of the ID
8956 cache API changes. Added idlist.c to client.
8958 * Also major rewrite on ID cache stuff on server as well.
8959 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8960 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8961 in hand, instead they are all put into the ID cache system now.
8962 All server_idlist_* routines uses ID cache now instead of
8963 traversing its own lists (those lists does not exist anymore).
8964 SilcIDList though still exists. Also, SilcXXXEntry's are
8967 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8969 * Finally made the SKE implementation compliant to the protocol
8970 specification. All mp integers are now binary encoded as
8971 opposed being HEX encoded.
8973 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8976 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8977 functions: silc_[encode/decode]_pem. Also added function
8978 silc_encode_pem_file to PEM encode with newlines ('\n') for
8981 * SILC public keys are now encoded either PEM or binary. Same
8982 option is for private keys as well. By default private keys
8983 are binary encoded and public keys PEM encoded. Silly HEX
8984 encoding were removed.
8986 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8987 function to create fingerprints.
8989 * Fixed a bug in SHA1; does not change the original data anymore.
8991 * Partly implemented INFO command on client and server side.
8992 Fixed CLEAR command. Changes to SERVER command; show current
8993 server(s) when giving command without arguments. Added
8994 VERSION command to client.
8996 * Added check to server that unregistered connections cannot
8997 execute commands (unless it is specificly allowed).
8999 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9001 * Fixed screen refresh.
9003 * Fixed channel joining bug from client. On some circumstances
9004 client tried to join to a channel it had already joined.
9006 * Added public key verification process into client's protocol.c.
9007 The client now verifies the public key from user and saves
9008 it into ~./silc/serverkeys/ directory.
9010 Added into: clientutil.[ch]: silc_client_verify_server_key.
9012 * Changed SKE protocol's silc_ske_initiator_finish function
9013 to accept callback function that verifies the received public
9014 key. Removed old silc_ske_verify_public_key function.
9016 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9018 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9019 silc_pkcs_private_key[_data]_set.
9021 * Made the password and public authentication more cleaner in
9022 server's protocol.c.
9024 * Removed historic and obsolete protocol `channel_auth' from
9025 both client and server.
9027 * Removed wrong way of sending command status messages from
9028 server to client in server's command.c. The old way violated
9029 protocol specification.
9031 Changes to silccore/silccommand.[ch]: removed
9032 silc_command_encode_status_payload -> not needed anymore,
9033 changed silc_command_encode_payload_va to accept extra
9034 argument on variable argument list. The argument type must
9035 now be provided to the function. Also, added new function:
9036 silc_command_encode_reply_payload_va which is same as
9037 normal command_encode_payload_va except command status type
9038 is provided as extra argument.
9040 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9042 * Added ~./silc directory handling. The directory includes the
9043 public and private keys for the client.
9045 Added silc_client_check_silc_dir, silc_client_create_identifier
9046 and silc_client_load_keys.
