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

1087 * Added more IM-like features by introducing new user modes
1088 for setting various presence information. Added new modes:
1089 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1090 specs and code. Protocol TODO #19. Affected files are
1091 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1092 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1094 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1096 * Added STATS command to the protocol after all, to return
1097 various statistical information about the network. It can
1098 be used by clients to retrieve statistical information, and
1099 servers may use it to to fetch cell and network wide
1100 statistics from router. Updated the protocol specs and
1101 implemented it to the server. Protocol TODO #16.
1102 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1103 silcd/command_reply.[ch].
1105 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * The LIST command reply in client libary now adds new channel
1108 entry if the returned channel doesn't exist yet in cache,
1109 and returns the channel entry to the application in the
1110 command_reply client operation. Affected file is
1111 lib/silcclient/command_reply.c.
1113 * Changed the channel message payload's MAC generation to
1114 include the IV in the MAC as well. This way all relevant
1115 parts of the channel message payload are authenticated also
1116 with the channel message MAC (and not only by packet MAC).
1117 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1118 Affected file is lib/silccore/silcchannel.c.
1120 * Fixed the SKE to save the remote version, since the
1121 silc_ske_parse_version mistakenly checked wrong version,
1122 after it replaced the start payload. Affected files are
1123 lib/silcske/silcske.[ch].
1125 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1127 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1128 string utility functions. Added there also new functions
1129 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1130 Affected files lib/silcutil/silcstrutil.[ch].
1132 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1133 files are lib/silcutil/silcstrutil.[ch].
1135 * Defined that the security property fields in SKE SHOULD be
1136 UTF-8 encoded, defined that version string MUST be US-ASCII
1137 encoded, defined that passphrases sent in connection
1138 authentication protocol MUST be UTF-8 encoded. Implemented
1139 these to the client and server. Defined also that other
1140 passphrases sent in the protocol MUST be UTF-8 encoded.
1141 Affected files are lib/silcske/silcske.c,
1142 lib/silcclient/protocol.c, silcd/protocol.c,
1143 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1145 * Changed the silc_client_close_connection interface to not
1146 need the SilcSocketConnection which should not be visible
1147 to application. Affected files are lib/silcclient/client.c
1148 and lib/silcclient/silcclient.h.
1150 * Rewrote the text for Private Message Key Payload in the
1151 protocol specification. Protocol TODO #11.
1153 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1155 * Upgraded the protocol version to 1.1, updated protocol specs
1158 * Added the nickname as new argument to NICK_CHANGE notify and
1159 added it to protocol specs and implemented it to client and
1160 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1161 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1162 lib/silcclient/client_notify.c.
1164 * Added the killer's client ID to the KILLED notify and added
1165 it to protocol specs and implemented it to client and server.
1166 Protocol TODO #13. Affected files are silcd/command.c,
1167 silcd/packet_receive.c, packet_send.[ch],
1168 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1169 The killer's client entry is now returned to application in
1170 the `notify' client operation.
1172 * Fixed the Max Argument fields that had too large value set
1173 in the protocol specs. Protocol TODO #14.
1175 * Added the LEAVE command reply to return the ID of parted
1176 channel. Updated protocol specs and implemented it to the
1177 client and server. Protocol TODO #15. Affected files are
1178 silcd/command.c, lib/silcclient/command_reply.c. The channel
1179 entry is now returned to application in the `command_reply'
1182 * Rewrote the version SKE version checking in client libary
1183 and in server to use the silc_parse_version_string. Affected
1184 files are lib/silcclient/protocol.c, silcd/protocol.c.
1186 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1187 commands that was missing it, and updated protocol specs and
1188 the server implementation. Protocol TODO #10. The affected
1189 file is silcd/command.c.
1191 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1192 generic reply to a generic request (REQUEST flag), and
1193 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1194 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1195 to define the payload for DATA flag. Added the flags to
1196 the implementation. Protocol TODO #9. Affected file is
1197 lib/silccore/silcchannel.h.
1199 Changed the client library to return the message length
1200 to application as well in the channel_message and private_message
1201 client operations. Affected files are
1202 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1203 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1204 and lib/silcclient/client_ops_example.c.
1206 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1207 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1208 the channel. Updated protocol specs and impelemented this
1209 to client and server. Protocol TODO #6. Affected files are
1210 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1211 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1213 Added new options m and M to CMODE command in Irssi SILC
1214 client to set these modes.
1216 * Deprecated all administrative commands from SILC protocol
1217 since they are highly implementation specific commands.
1218 Updated protocol specs. Moved the old commands in
1219 implementations to private range of command types. Affected
1220 files are silcd/command.c, lib/silcclient/command.c and
1221 lib/silcclient/command_reply.c. Protocol TODO #8.
1223 * Fixed a bug in server where sending unknown command crashes
1224 the server. Affected file silcd/command.c.
1226 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1228 * Added SILC_PROTOCOLVERSION macro to check protocol version
1229 of a socket connection. The affected file is
1230 lib/silcutil/silcsockconn.h.
1232 * Added better error logging in rekey protocol. Affected file
1235 * Do not check public key types in SKE during rekey. Affected
1236 file lib/silcske/payload.c.
1238 * Fixed the rekey protocol with PFS, which was totally broken.
1239 Affected file silcd/protocol.c.
1241 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1243 * Some client implementations quit network by doing first LEAVE
1244 and then immediately SIGNOFF (like Bombyx). We now do check
1245 after a short time after LEAVE notify and check whether the
1246 client is still valid after LEAVE, and if not we remove it from
1247 cache. Affected file is lib/silcclient/client_notify.c.
1249 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1251 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1252 it's good not to have security holes here.
1254 * Fixed a negative refcount situtuation for the config context.
1255 Affected file is silcd/serverconfig.c.
1257 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1259 * ROBOdoc documented lib/silcutil/silcutil.h.
1261 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1263 * Optimized even more the SilcPacketContext structure. Now
1264 totally saved 16 bytes of memory per context after optimization.
1265 Affected files are lib/silccore/silcpacket.[ch].
1267 * Made strict checks for valid SILC IDs. Affected file is
1268 lib/silccore/silcid.c.
1270 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Changed the object argument for silc_cipher_register,
1273 silc_hash_register, silc_hmac_register and silc_pkcs_register
1274 to const. Affected files are lib/silccrypt/silccipher.[ch],
1275 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1277 * Changed the silc_get_username and silc_get_real_name to
1278 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1280 * Fixed the Irssi SILC Client to use the silc_get_username and
1281 silc_get_real_name insted of glib routines since the glib
1282 routines only corrupt stack. Fixes the Irssi SILC to work in
1283 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1285 * Fixed the Irssi to not use g_get_home_dir since it crashes
1286 or returns garbage on cygwin and corrupts stack. Added function
1287 get_home_dir to Irssi routines. Affected files are
1288 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1290 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1292 * Made some structure optimizations. SFTP memory FS MemFSEntry
1293 entry structure. Optimized SilcTask structure. Optimized
1294 SilcPacketContext structure.
1296 Affected files lib/silcsftp/sftp_fs_memory.c,
1297 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1299 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * And yet again reverted back the config thing since Johnny
1302 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1305 * Fixed memory leaks from config object. Affected files are
1306 silcd/serverconfig.[ch].
1308 * Added support for adding new connections to the server in rehash.
1309 After rehash they take effect.
1311 Added support for changing the maximum allowed connections in
1312 rehash. The number can grow but going smaller is not supported.
1314 Added function silc_server_num_sockets_by_remote to the
1315 silcd/server_util.[ch].
1317 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1319 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1321 * Added preliminary checking during config parsing for a valid
1322 public/private key and removed further checks in the code.
1323 Affected files are silcd/serverconfig.[ch], server.c.
1325 * Moved functions silc_server_drop() and silc_server_daemonise()
1326 from server.c to silcd.c since they are stricly related to
1327 the application activity.
1329 * Reverted a small part of the automatic ref/unref since
1330 it caused a double unref in some situations. Affected
1331 files are silcd/silcd.[ch], server.c, serverconfig.c.
1333 * Added some .cvsignore files in the lib directory.
1335 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1337 * Fixed silc_net_gethostbyaddr to correctly resolve by
1338 address. Affected file lib/silcutil/silcnet.c.
1340 * Fixed the notify relaying to client. The HMAC to be used
1341 with relayed packets ws wrong and caused decryption failure
1342 at the client end. Affected file is silcd/packet_receive.c.
1344 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * Created new branch silc_protocol_1_0_branch.
1348 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1350 * Changed the silc_server_config_* routines to be SilcServer
1351 independent. They are now officially application specific code
1352 and not part of generic server implementation. Affected files
1353 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1355 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1357 * Added automatic referencing of config context in the
1358 silc_server_config_alloc, and automatic unreferencing in the
1359 silc_server_config_destroy. Affected files are
1360 silcd/serverconfig.[ch], silcd/silcd.c.
1362 * Fixed the silc_log_quick handling in the logging routines.
1363 It didn't log quickly when it was TRUE. Affected file is
1364 lib/silcutil/silclog.c. Also the flush delay was set even
1365 if it was 0 in config file. Affected file is
1366 silcd/serverconfig.c.
1368 * Added support for changing key pair of the server in rehash.
1369 Affected file silcd/server.c.
1371 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1373 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1374 too early, before getting the channel entry. Affected file
1375 is silcd/packet_receive.c.
1377 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1379 * Added functions silc_server_config_[ref/unref], these are used
1380 to prevent that the config object is destroyed.
1382 No longer directly affect global variables silc_log_quick and
1383 silc_log_delay, they are first cached inside the config object
1384 and then applied with silc_server_config_setlogfiles().
1386 silc_server_config_set_defaults() is now internal to
1387 serverconfig.c, there are no reasons to show this internal stuff
1390 Affected files are silcd/serverconfig.[ch].
1392 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1393 fprintf's to stderr, since some code may be executed again after
1394 the server went into the background. Affected files are
1397 * Added rehash support. Added function silc_server_rehash() that
1398 will perform all the basic tasks of the rehashing procedure.
1400 * Added command line option `-x, --hexdump'. This will enable the
1401 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1402 The option `--hexdump' implies `--debug'.
1404 * Fixed a bad bug in the logging APIs (silcutil library) where
1405 the application would crash after calling silc_log_reset_all().
1407 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1409 * Fixed the KICKED notify handling in client library to
1410 correctly remove the channel and all entries from the
1411 channel when I was kicked. This bug crashed the client.
1413 Fixed yet another but in KICKED notify handling to remove
1414 the kicked client correctly from the channel.
1416 Affected file is lib/silcclient/client_notify.c.
1418 * Fixed a minor bug in looking up correct client entry
1419 in KICKED notify in server. Affected file is
1420 silcd/packet_receive.c.
1422 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1423 sources correctly to distribution. Fixes --with-gmp option.
1425 * Removed the manual rehashing from ID Cache, and changed it
1426 to use the SILC Hash Table's auto rehash feature. Affected
1427 file is lib/silccore/silcidcache.c.
1429 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1431 * Fixed a bug in the silc_client_nickname_format function that
1432 handles the multiple same nickname formatting. Two clients
1433 with same nickname caused problems after the first one left
1434 and rejoined. It didn't format the nickname correctly.
1435 Affected file is lib/silcclient/idlist.c.
1437 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1439 * Don't change the topic if olod topic is same as new one.
1440 Affected file is silcd/packet_receive.c.
1442 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1444 * Added cross-reference support to the SILC Documentation
1445 generator. All types across all HTML files are now cross-
1446 referenced. Affected files util/robodoc/generator.c and
1447 scripts/silcdoc/silcdoc.
1449 * Added file lib/silcutil/silctypes.h to include all the
1450 arithmetic type definitions and some macros. Removed
1451 includes/bitmove.h and moved macros to silctypes.h.
1453 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1455 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1459 * Added `type' argument to silc_id_payload_parse_id function which
1460 now returns the type of the ID to the sent pointer. Affected
1461 file is lib/silccore/silcid.[ch].
1463 * Added check for CMODE_CHANGE notify type that mode change is
1464 allowed by the sender. Affected file silcd/packet_receive.c.
1466 * Added check for CUMODE_CHANGE notify type that mode change is
1467 allowed by the sender. Affected file silcd/packet_receive.c.
1468 Added the ID type as CUMODE_CHANGE notify type as argument
1469 to the `notify' client operation. Affected files are
1470 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1472 * Added function silc_client_add_server to the client library.
1473 Added support for resolving also channel and server info when
1474 received unknown entity in notify packet. Affected files are
1475 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1477 * Added function silc_command_get_status to return the command
1478 status from the command reply's argument payload. Affected files
1479 are lib/silccore/silccommand.[ch].
1481 * Added check for KICKED notify type that the kicking is
1482 allowed by the client. Affected file silcd/packet_receive.c.
1484 * Created function silc_get_input which can be used to get input
1485 (echo on or off) from user on command line. Affected files are
1486 lib/silcutil/silcutil.[ch].
1488 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1490 * Optimized silc_server_packet_relay_to_channel function.
1491 Added new function silc_channel_message_payload_encrypt which
1492 can be called directly if channel message payload needs to
1493 be encrypted and is already encoded (no need to call _encode
1494 function). Packet relaying is now done by router without any
1495 extra memory allocations. Affected files are
1496 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1497 silcd/packet_send.c.
1499 * Fixed the INVITE notify handling. It took wrong arguments
1500 as invite list and invite delete. Affected file is
1501 silcd/packet_receive.c.
1503 * Added check for TOPIC_SET notify type that the topic change is
1504 allowed by the client. Affected file silcd/packet_receive.c.
1506 * Added check for INVITE notify type that inviting is allowed by
1507 the client. Affected file silcd/packet_receive.c.
1509 * Changed the silc_server_client_on_channel to return the
1510 SilcChannelClientEntry as well. Moved the function
1511 silc_server_check_cmode_rights to server_util.[ch].
1512 Affected files are silcd/server_util.[ch], silcd/command.c.
1514 * Added function silc_server_check_umode_rights to check whether

1516 UMODE_CHANGE notify type that the umode change is allowed
1517 by the client. Affected files are silcd/server_util.[ch],
1518 silcd/packet_receive.c and silcd/command.c.
1520 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1522 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1523 ID length. It ignored that ID can be IPv6 based as well.
1524 Affected file lib/silccore/silcpacket.h.
1526 * Fixed the silc_id_id2str and silc_id_str2id to take the
1527 IPv6 address offset's into consideration. Affecte file is
1528 lib/silccore/silcid.c.
1530 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1532 * Fixed the internal Unix scheduler functions to check for
1533 NULL context they may receive. The affected file is
1534 lib/silcutil/unix/silcunixschedule.c.
1536 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1538 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1539 can specify different directory with --home command line
1540 parameter. Affected files irssi/src/silc/core/client_ops.c,
1543 * SILC-specific commands aren't now executed if the active server
1544 isn't of SILC-type, so there won't be problems with having
1545 IRC and SILC protocol support in same client. Affected files
1546 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1549 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1551 * Improved the signal support in SILC Schedule. Added new
1552 function silc_schedule_signal_call which is used by application
1553 to mark a signal to be called. It is now safe to perform
1554 any kind of tasks in signal callbacks since it is guaranteed
1555 that the application specified signal callback is called
1556 after the signal is over. Affected files are
1557 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1559 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1561 * Added `name' field to SilcChannelPrivateKey to represent
1562 application given name for the key. Moved also the context from
1563 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1564 Added the `name' argument also to the function
1565 silc_client_add_channel_private_key.
1567 Added function silc_client_current_channel_private_key to set the
1568 current channel private key in use.
1570 Added "change" command to KEY command which can be used to change
1571 the current channel private key. Bound the command also to
1572 alt+K (Alt+Shift+k).
1574 Also affected files lib/silcclient/client_channel.c,
1575 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1577 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1579 * Added silc_rng_get_byte_fast function in to the
1580 lib/silccrypt/silcrng.[ch].
1582 * Changed the interface of silc_packet_assemble and the
1583 silc_packet_send_prepare. If silc_packet_assmble is now
1584 called the application does not call silc_packet_send_prepare
1585 because the library will call it automatically. These
1586 interfaces now also return a reference to the outgoing buffer
1587 which includes the assembled packet, which the application can
1588 use to encrypt the packet.
1590 Affected files are lib/silccore/silcpacket.[ch],
1591 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1592 silcd/packet_send.c, server_backup.c and packet_receive.c.
1594 * Fixed a packet sending bug on very high load, where outgoing
1595 packet queue wasn't handled correctly and packets got corrupted.
1596 Affected files are lib/silcutil/*/silc*sockconn.c,
1597 lib/silcclient/client.c and silcd/server.c.
1599 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1601 * Added macro SILC_PACKET_DATALEN which can be used during
1602 packet assembling to check whether the data to be added to
1603 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1604 len is truncated until it fits it.
1606 Added checks for maximum length of channel message payload and
1607 private message payload also.
1609 Added checks for maximum packet length in server and in
1612 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1613 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1614 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1615 lib/silcclient/client_prvmsg.c.
1617 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1619 * Added silc_server_packet_queue_purge call to the
1620 silc_server_disconnect_remote to assure that all data in the
1621 queue before disconnecting is sent to the network. Affected
1622 file silcd/server.c.
1624 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Added the deleting of server's own ID cache entry to the
1627 silc_server_free function. Free also everything else that
1628 has been allocated in silc_server_init. The affected file
1631 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1633 * Added functions silc_parse_version_string, silc_version_to_num,
1634 and silc_ske_parse_version to parse SILC protocol style version
1635 strings. Affected files lib/silcutil/silcutil.[ch] and
1636 lib/silcske/silcske.[ch].
1638 * Added new configuration params: version_protocol, version_software
1639 and version_software_vendor to specify what version the remote
1640 host must at least be to be able to connect to server. The vendor
1641 string can be regex matched too. Added new function
1642 silc_server_connection_allowed to check maximum number of allowed
1643 connections, and allowed versions for incoming connections.
1644 Affected files are silcd/server.c, server_util.[ch] and
1647 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1649 * Added preliminary support for signals in scheduler. The
1650 signals we care about are now blocked always when the scheduler
1651 is locked. This way we can synchronise the use of signal with
1652 scheduler. It is guaranteed that when signal occurs the scheduler
1653 is not locked, and thus new tasks can be safely added to the
1656 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1657 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1658 Added new platform specific routines
1659 silc_schedule_internal_signals_[un]block and
1660 silc_schedule_internal_signal_[un]register.
1662 Added new functions to SILC Schedule API:
1663 silc_schedule_signal_[un]register. Each signal that application
1664 is going to use should be registered to the scheduler.
1666 Affected files are lib/silcutil/silcschedule.[ch],
1667 lib/silcutil/*/silc*schedule.c.
1669 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1671 * Check for unauthenticated client and server in the
1672 silc_server_new_client and silc_server_new_server functions.
1673 Affected file silcd/packet_receive.c.
1675 * Added function silc_string_is_ascii to check whether given
1676 string is 7-bit ASCII string. Affected files are
1677 lib/silcutil/silcutil.[ch].
1679 * Added function silc_id_is_valid_server_id into the
1680 silcd/serverid.c and added checking for valid Server ID's in
1681 silc_server_new_server. The Server ID must always be based
1682 on the server's public IP address.
1684 * Added logging of DISCONNECT packet message in the server.
1685 Affected file silcd/server.c.
1687 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1689 * Changed all library interfaces that use Global RNG to also
1690 accept SilcRng as argument. Affected files are
1691 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1692 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1693 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1694 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1695 lib/silccrypt/rsa.c.
1697 * Added function silc_pkcs_generate_key to the
1698 lib/silccrypt/silcpkcs.[ch] for applications so that they
1699 don't need to do pkcs->pkcs->init calls anymore.
1701 * Remove SilcSocketConnection from the SFTP API since it really
1702 wasn't needed there. The application has the information
1703 saved in its contexts anyway and the SFTP layer doesn't need
1704 know about it. Affected files lib/silcsft/silcsftp.h and
1705 lib/silcsftp/sftp_[server/client].c.
1707 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1708 The SilcSimContext is not SilcSim.
1710 * Fixed possible buffer overflows in silc_id_render in the
1711 lib/silcutil/silcutil.c.
1713 * On EPOC the global crypto module lists are not used at all
1714 in the crypto library. Added support for using the constant
1715 algorithm list on EPOC. Affected files are
1716 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1719 * Fixed the handling of third parameter of KICKED notify, since
1720 it was mistakenly updated to SILC Protocol 1.0 even though it
1721 is to be included in 1.1. Since it is not in 1.0 it is not
1722 mandatory, and this fix now handles it only if it is provided,
1723 and it is not error if it is not provided. Affected file
1724 lib/silcclient/client_notify.c.
1726 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1728 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1729 client. Affected file irssi/src/silc/core/client_ops.c.
1731 * Merged with Irssi 0.8.4 from irssi.org CVS.
1733 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1735 * Check for valid socket connection in client entries before
1736 sending any messages. Fixes a crash, but doesn't fix some
1737 other underlaying bug that is lurking there. Affected
1738 file silcd/packet_send.c.
1740 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1742 * $usermode, $cumode and $cumode_space expandos shouldn't do
1743 anything with non-SILC server records. Affected file
1744 irssi/src/silc/core/silc-expandos.c
1746 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1748 * Fixed the silc_net_check_[host/local]_by_sock to support
1749 IPv6 bound sockets as well. Now they can return IPv6 addresses
1750 as well. Affected file lib/silcutil/silcnet.c.
1752 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1753 Affected lib/silcutil/unix/silcunixnet.c.
1755 * Fixed ID rendering (at least on some platforms, not NetBSD)
1756 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1758 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1760 * Added silc_hash_public_key and silc_hash_public_key_compare
1761 functions to be used with SilcHashTable. They can be used to
1762 hash public keys and compare public keys in hash table. Affected
1763 file lib/silcutil/silcutil.[ch].
1765 * Added support for specifying multiple public keys for Client
1766 connection section in server configuration file. This makes it
1767 possible to accept multiple public keys from same host, or to
1768 make a section that accepts any incoming host, and have the
1769 accepted public keys listed in the section.
1771 Added functions silc_sever_[find/get]_public_key, added the
1772 support for this actually to all connection sections but only
1773 the Client section is currently allowed to specify multiple
1776 Affected files are silcd/server.c, server_internal.h,
1777 command.c, protocol.c, server_util.[ch], packet_receive.c.
1779 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1781 * Merged Irssi 0.8.2 from irssi.org CVS.
1783 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1785 * If silc_debug is TRUE, also output standard logging messages
1786 to stderr with the debug output.
1788 Made silc_log_reset_all() flushing all channels before returning.
1789 Also fixed some documentation typos.
1791 Affected files are lib/silcutil/silclog.[ch].
1793 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1795 * Fixed the server to check correctly the amount of connections
1796 from single host, by checking also the type of the connection.
1797 Fixed also the comparison of number of connections and number
1798 of allowed connections. Affected files are silcd/server.c,
1801 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1803 * Fixed the USERS command reply to save the user's mode on the
1804 channel as well. Fixed JOIN command reply to check whether a
1805 client is on channel already and not join it twice. Affected
1806 file lib/silcclient/command_reply.c.
1808 * Added new file silc-expandos.c into irssi/silc/core/ to return
1809 various stuff for various signal for the statusbar etc. updating.
1810 Now Irssi SILC client prints channel user modes etc. on the
1813 * The user mode (like server/router operator changes) is now shown
1814 on the Irssi SILC client's statusbar. The affected files are
1815 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1817 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1819 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1820 to SILC_SCHEDULE_[UN]LOCK macros.
1822 * Added more error printing to logs in server code. Affected
1823 files silcd/server.c and silcd/protocol.c.
1825 * Fixed -S option parsing in Irssi SILC Client. Affected file
1826 irssi/src/silc/core/silc-core.c.
1828 * Added silc_buffer_alloc_size function. Affected file is
1829 lib/silcutil/silcbuffer.h.
1831 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1833 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1834 constants. Affected files in
1835 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1838 * Changed the internal SFTP Memory FS table to const. Affected
1839 file lib/silcsftp/sftp_fs_memory.c.
1841 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1843 * Fixed the buffer formatting and unformatting routines to
1844 check the size of 64 bits types with sizeof(). Affected
1845 file is lib/silcutil/silcbuffmt.c.
1847 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1849 * Removed 0.6.x backwards support.
1851 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1853 * Changed all integer type names:
1854 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1855 to avoid collisions with other libraries using same type names
1858 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1860 * Added `prefer_ipv6' argument to the functions
1861 silc_net_gethostbyname[_async]. If it is TRUE it will return
1862 IPv6 address over IPv4. If FALSE IPv4 address is returned
1863 even if IPv6 address was found. Affected files
1864 lib/silcutil/silcnet.[ch].
1866 * Added support silc_net_create_connection[_async] to fallback
1867 to IPv4 address if IPv6 address could not be used (like if
1868 it doesn't work on a specific system). Affected file in
1869 lib/silcutil/unix/silcunixnet.c.
1871 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1873 * Added silc_schedule_reinit function to do the enlarging
1874 of the max tasks handling capabilities of the scheduler.
1875 Affected files lib/silcutil/silcschedule.[ch].
1877 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1879 * Added automatic extern "C" { ... } for C++ compilers so the
1880 application does not need to define them. Affected file
1881 includes/silcincludes.h.
1883 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1884 old name went against naming convention. Applications now
1885 include "silcclient.h" instead of "clientlibincludes.h".
1886 Removed includes/clientlibincludes.h, it is redundant now.
1888 * Renamed includes/version.h to silcversion.h.
1890 * Added really preliminary support for OS/2 into the util
1891 library. Only thread & mutex API is implemented, others
1892 are still to be implemented. Created the lib/silcutil/os2/
1893 directory. Created also file includes/silcos2.h.
1895 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1897 * Added preliminary BeOS support into the util library.
1898 Created lib/silcutil/beos/, and implemented all the needed
1899 functions to support SILC on BeOS. Created also file
1900 includes/silcbeos.h.
1902 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1904 * Added proper initializations to silc's irssi code, so it's
1905 now possible to load it as module. Affected files
1906 irssi/src/silc/core/silc-core.c,
1907 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1909 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1911 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1914 * Fixed the silcdoc document generator to correct generate
1915 docs from all kinds of filenames. Affected files are
1916 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1918 * ROBOdoc documented lib/silcutil/silcmemory.h.
1919 Added also new function silc_memdup.
1921 * Removed lib/silcutil/silcbufutil.h and moved those routines

1924 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1926 * Added `user_count' to the SilcChannelEntry which now tells the
1927 number of users on the channel. The user count is now saved
1928 in normal server of global channels as well. Affected files
1929 silcd/server.c, idlist.h, packet_receive.c and command.c.
1931 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1932 include file utility functions.
1934 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1935 instead of calling directly OS routines.
1937 * Fixed NICK change printing in Irssi SILC Client. Fixed
1938 KICKED notify printing in Irssi SILC Client. Affected file
1939 irssi/src/silc/core/client_ops.c.
1941 * Fixed a NICK change bug in client library, to not recreate the
1942 client_entry->channels hash table everytime nick is changed.
1943 Affected file lib/silcclient/client.c.
1945 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1947 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1948 the SKE interface a bit.
1950 * Fixed padding problem in PKCS#1. The padding was not actually
1951 random since the random number generator was used incorrectly.
1952 This security bug affects only when encrypting with PKCS#1, and
1953 it is not currently used at all in SILC. SILC only use signing
1954 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1956 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1958 * Rewrote the notify handling in Irssi SILC client to not call
1959 the events as signals. Fixes problems with Perl support.
1960 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1962 * Send the auto-nicking NICK command in client library with
1963 little timeout after connecting. The affected file is
1964 lib/silcclient/client.c.
1966 * Added following new config file settings:
1967 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1968 key_exchange_timeout, conn_auth_timeout, connections_max,
1971 Implemented all the new config settings handling in the server.
1973 Optimized the use of SKE Mutual flag usage. Use it only
1974 if connection authentication protocol is not based in public
1977 Renamed all SilcServerConfigSection* to SilcServerConfig*
1978 to have a bit shorter names.
1980 Affected files silcd/serverconfig.[ch], server.[ch], and
1983 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1985 * Cleaned up the listening sockets code, preparing for the rehash
1986 support. Affected file is silcd/server.c.
1988 * Fixed some output messages. Affected files are silcd/silcd.c,
1991 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1993 * Create lib/doc/silcrng_intro.html document as introduction
1994 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1996 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1998 * Fixes to the silcd config template. Affected file is
1999 doc/example_silcd.conf.in.
2001 * Removed type casts from silc_calloc(), conforming to the
2002 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2004 * Removed param_name member from client, server, and router
2005 section structs, now identifying the param directly.
2007 Added CONFIG_FREE_AUTH macro in config file parsing.
2009 Affected files are silcd/serverconfig.[ch].
2011 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2013 * Fixed command line parameter handling. All SILC initialization
2014 is now done in silc_core_init() which also fixes autoconnecting
2017 Affected files irssi/src/silc/core/silc-core.c,
2018 irssi/src/fe-text/silc.c.
2020 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2022 * Added new configuration options and blocks:
2023 keepalive_secs, reconnect_count, reconnect_interval,
2024 reconnect_interval_max, reconnect_keep_trying and
2025 require_reverser_lookup. Added ConnectionParam block, and
2026 implemented the connection parameters when connecting as
2027 initiator and when accepting connections as responder.
2029 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2030 whether given configuration value has been given already.
2032 Affected files silcd/serverconfig.[c], server.[c].
2034 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2035 algorithm parts and created new file silcalgs.conf, that
2036 is now included from the example_silcd.conf.in.
2038 * Optimized the silc_server_connect_to_router_second to take
2039 the connection configuration object from the SilcServerConnection
2040 object instead of finding it during the connecting phase.
2041 Added the configuration object to SilcServerConnection struct.
2042 Affected files silcd/server_internal.h, server.c.
2044 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2046 * Add the client on channel after it was resolved at the
2047 channel message receiving, and it was not already on the
2048 channel. Affected file lib/silcclient/client_channel.c.
2050 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2052 * Fixed the public key authentication to allocate always the
2053 destination signature buffer instead of using static buffer.
2054 Affected file silcd/protocol.c.
2056 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2058 * Unified the serverconfig.[ch]'s helper function interface.
2059 Affected file silcd/serverconfig.[ch].
2061 * Removed doc/example_silc.conf.in since it is redundant.
2062 The make install will now install irssi/silc.conf file.
2064 * Added new Passphrase and Publickey authentication methods to
2065 config file, allowing both public key and passphrase based
2066 authentication to be set at the same time.
2068 Added `prefer_passphrase_auth' setting in config file which
2069 can be used to set to prefer passwd auth if both passwd and
2070 public key is set. If not set, public key is preferred.
2071 This has effect only when being initiator (responder will try
2074 Added support for authentication with passphrase and public key
2075 at the same time. The passphrase is tried first always since
2076 it is faster to check.
2078 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2080 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2082 * Merged the new SILC Config library, with the server parsing
2083 support. Read the header file silcconfig.h or the toolkit
2084 documentation for the news. Affected files are
2085 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
2086 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
2087 silcd/protocol.c silcd/server.c silcd/server_backup.c
2088 silcd/serverconfig.[ch] silcd/silcd.c.
2090 * Fixed some silclog documentation. Affected file is
2091 lib/silcutil/silclog.h.
2093 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2095 * The silc_cipher_register, silc_hash_register and
2096 silc_hmac_register now checks if the object to be registered
2097 is registered already. Affected files are
2098 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2100 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2102 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

2106 * Allow zero length channel messages inside the Channel Message
2107 Payload. Affected file lib/silccore/silcchannel.c.
2109 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2110 as header filenames.
2112 * Removed lib/silcclient/README and created HTML file
2113 lib/silcclient/silcclient_using.html, which is now included
2114 as part of Toolkit documentation.
2116 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2118 * Fixed CUMODE_CHANGE notify handling to change the mode of
2119 correct client. Affected file lib/silcclient/client_notify.c.
2121 * Make silc_rng_alloc fail if it cannot allocate the sha1
2122 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2124 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2126 * Fixed the file transfer's key agreement payload to include
2127 zero port also if the hostname is NULL because it could not
2130 Call file transfer monitor callback now also if error occurs
2131 during key agreement protocol.
2133 Changed the silc_client_file_send interface to return the
2134 SilcClientFileError instead of session id. The session ID
2135 is returned into pointer provided as argument.
2137 Check that the file exists locally before sending the
2138 file transfer request at all.
2140 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2142 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2143 error than can occur while key agreement protocol. Affected
2144 file lib/silcclient/silcapi.h.
2146 * Fixed the event_mode CMODE handler to not crash when mode
2147 is changed and +k mode is set in the channel. Affected file
2148 irssi/src/silc/core/silc-channels.c.
2150 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2151 SILC_LOG_WARNING to give out Warning and not Error. Affected
2152 file lib/silcutil/silclog.c.
2154 * Fixed the channel message payload decryption in the function
2155 silc_channel_message_payload_decrypt to not modify the original
2156 buffer before it is verified that the message decrypted
2157 correctly. Otherwise, next time it is called with correct
2158 channel key it won't encrypt since the payload is corrupted.
2159 Affected file lib/silccore/silcchannel.c.
2161 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2163 * Do not constantly resize the window. A fix patch by cras.
2164 Affected file irssi/src/fe-text/screen.c.
2166 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2168 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2169 Affected file lib/silcutil/silcnet.c.
2171 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2173 * Fixed a bug in hash table internal routine for traversing
2174 the table with foreach callback. The current entry may
2175 become invalid in the callback but it was referenced after
2176 the callback returned.
2178 Do not allow auto rehashing of hash table during the
2179 silc_hash_table_foreach operation, for same reasons as it is
2180 not allowed for SilcHashTableList. Affected files are
2181 lib/silcutil/silchashtable.[ch].
2183 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2185 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2186 Win32 DLL. extern's in header files are now declared with
2189 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2191 * Fixed private message handling. It used some old code that
2192 caused the client to crash. Affecte file is
2193 lib/silcclient/client_prvmsg.c.
2195 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2197 * Added function silc_client_add_channel,
2198 silc_client_replace_channel_id, and removed functions
2199 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2200 from client library.
2202 * Added cross reference of the joined channels to the
2203 SilcClientEntry, and changed the SilcChannelEntry's
2204 users list to SilcHashTable. The affected files are
2205 lib/silcclient/idlist.[ch].
2207 * Fixed a bug in hash table tarversing. While the hash table
2208 is traversed with SilcHashTableList the table must not be
2209 rehashed. It is now guaranteed that auto rehashable tables
2210 are not rehashed while tarversing the list. Also defined that
2211 silc_hash_table_rehash must not be called while tarversing
2212 the table. Added function silc_hash_table_list_reset that must
2213 be called after the tarversing is over. The affected files are
2214 lib/silcutil/silchashtable.[ch].
2216 * Changed all hash table traversing to call the new
2217 silc_hash_table_list_reset in server and in client library.
2219 * Added function silc_client_on_channel to return the
2220 SilcChannelUser entry if the specified client entry is joined
2221 on the specified channel. This is exported to application as
2222 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2224 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2226 * Fixed founder regaining problem with JOIN command on normal
2227 server. The notify for mode change must be sent always and
2228 not only if !cmd->pending. Affected file silcd/command.c.
2230 * Fixed the WHOWAS command's reply sending to support the
2231 lists correctly. Affected file silcd/command.c.
2233 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2235 * When sending JOIN command to router for processing the
2236 sender's old command identifier was not saved back to the
2237 sender's command context, fixed now. The affected file is
2240 * Create the key in JOIN command of the router did not return
2241 the channel key, added check for this. Affected file is
2244 * Fixed a channel ID update bug in JOIN command reply. Do
2245 not directly upgrade the ID but call the function
2246 silc_idlist_replace_channel_id if the ID was changed.
2247 Affected file silcd/command_reply.c.
2249 * Fixed memory leaks from command calling if it would fail.
2250 Affected file silcd/command.c.
2252 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2254 * Applied patches from cras:
2256 Memory leak fixes around libaries, irssi window resize fix,
2257 new silclist.h and silcdlist.h, all extern inline changed to
2260 * Removed dotconf from lib/dotconf, not needed anymore.
2262 * Removed TRQ from lib/trq, not needed anymore.
2264 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2265 with server connections. Later this will be configurable
2266 in config file after new config file is done. Affected file
2269 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2271 * Fixed a crash in server related to channel announcements.
2272 Affected file silcd/server.c.
2274 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2276 * Fixed memory leaks in silc_server_create_new_channel*
2277 functions. Affected file silcd/server.c.
2279 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2280 which ID was changed. This way the router will send the
2281 user list for the channel again, and server won't be in
2282 desync in some rare circumstances. Affected file is
2283 silcd/packet_receive.c.
2285 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2287 * Check for NULL socket pointer in the function
2288 silc_server_packet_send_to_channel_real. Affected file
2289 silcd/packet_send.c.

2292 list. Affected file silcd/packet_receive.c.
2294 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2296 * Fixed some header addition to Toolkit distribution in
2297 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2299 * Added lib/silcclient/client_ops_example.h as an template
2300 file for application programmers to quickly start using
2301 the SilcClientOperation functions in their application.
2302 Updated the lib/silcclient/README as well to tell about this
2303 nice file made available.
2305 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2307 * Call silc_server_remove_from_channels when removing client
2308 entry when NO_SUCH_CLIENT_ID was received. Affected file
2309 is silcd/command_reply.c.
2311 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2313 * Added server & router operator statistics updating. Affected
2314 file silcd/packet_receive.c and silcd/command.c.
2316 * Fixed the SERVER_SIGNOFF notify handling on normal server
2317 not to save the history information for clients. Same was
2318 fixed earlier in remove_clients_by_server function, but not
2319 here. Affected file silcd/packet_receive.c.
2321 * Raised the default connection-retry count from 4 to 7 in
2322 server. Affected file silcd/server.h.
2324 * Cancel any possible reconnect timeouts when we start the
2325 key exchange. Affected file silcd/server.c.
2327 * Do not reconnect on connection failure when SCONNECT was
2328 given. Affected files silcd/server.[ch].
2330 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2332 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2334 * Fixed the NICK command to always give the unformatted
2335 nickname to the one giving the NICK command. If unformatted
2336 nickname is cached already it will be formatted and the
2337 local entry will always get the unformatted nickname.
2338 Affected file lib/silcclient/idlist.c.
2340 * Fixed some double frees from client library commands.
2341 Affected file is lib/silcclient/command.c.
2343 * Fixed CUMODE command in server to assure that no one can
2344 change founder's mode than the founder itself, there was a
2345 little bug. Affected file silcd/command.c.
2347 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2349 * Removed the SilcClientCommandDestructor from the client
2350 libary, it is not needed anymore. Affected files are
2351 lib/silcclient/silcapi.h, command[_reply].[ch],
2352 client_notify, idlist.c.
2354 * Fixed GETKEY command to first resolve client, and then
2355 resolve the server only if the client was not found, instead
2356 of resolving both at the same time. Affected file is
2357 lib/silcclient/command.c.
2359 * Added silc_client_start_key_exchange_cb and lookup the
2360 remote hostname and IP address before starting the key
2361 exchange with server. The affected file is
2362 lib/silcclient/client.c.
2364 * The server's public key is now saved using the IP address
2365 of the server and not the servername for the filename.
2366 The hostname public key filename is checked as an fall back
2367 method if the IP address based filename is not found.
2369 Fixed the GETKEY command to save the fetched server key
2370 in correct filename.
2372 Print the remote server's hostname now when new key is
2373 received during connection process. Affected file is
2374 irssi/src/silc/core/client_ops.c.
2376 * Return always our own public key to the client if it asks
2377 for it with GETKEY command. Affected file silcd/command.c.
2379 * Removed the use_auto_addr variable from default config
2380 file since it was in wrong section. Affected file is
2383 * Fixed TOPIC_CHANGE notification to not route it when it
2384 was sent using silc_server_send_notify_to_channel function.
2385 Affected file silcd/command.c.
2387 * Fixed silc_server_send_notify_kicked to send the kicker's
2388 Client ID also, it was missing. Affected files are
2389 silcd/command.c, silcd/packet_send.[ch].
2391 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2393 * Do not save client history information in SERVER_SIGNOFF.
2394 Fixes the bug in normal server that it does not detect
2395 the client becoming valid after the server becomes back
2396 online. Affected file silcd/server_util.c.
2398 * Added `sock_error' field into the SilcSocketConnection
2399 context. When error occurs during socket operation (read
2400 or write) the error is saved. Added also new function
2401 silc_socket_get_error to return human readable socket error
2402 message. Affected files are lib/silcutil/silcsockconn.[ch],
2403 lib/silcutil/unix/silcunixsockconn.c, and
2404 lib/silcutil/win32/silcwin32sockconn.c.
2406 * The server now prints the socket error message in the
2407 signoff for client. Affected file silcd/server.c.
2409 * Fixed the `created' channel information sending from router
2410 to server in JOIN command. Checks now whether the channel
2411 really was created or not and set it according that.
2413 Fixed the JOIN command to use the client entry's current
2414 ID during the joining procedure instead of the one it sent
2415 in the command (it is checked though), since it can change
2416 between the packet processing and command processing, and
2417 would just case unnecessary pain in the client end. Affected
2418 file silcd/command.c.
2420 * Fixed a channel key payload sending to use correct channel
2421 ID when the server was forced to change the channel's ID by
2422 router. Router sent the key payload with the old Channel ID.
2423 Affected file silcd/packet_receive.c.
2425 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2427 * Call silc_server_save_channel_key only if the key payload
2428 was provided in the JOIN command's command reply. Affected
2429 file silcd/command_reply.c.
2431 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2433 * Fixed silc_mp_sizeinbase to return the value correctly with
2434 MPI. Affected file lib/silcmath/mp_mpi.c.
2436 * Fixed the stop_server signal to correctly stop the scheduler
2437 and gracefully stop the server when SIGTERM or SIGINT signals
2438 are received. Affected file silcd/silcd.c.
2440 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2442 * Simple handling of TERM and HUP signals. Also added some log
2443 flushing call around. Affected file is
2446 * Fixed small bugs in silclog.c. Now buffering output will take
2447 effect after 10 seconds since startup: This will ensure that
2448 no important startup messages are lost. Also output redirection
2449 will preserve original format ([Date] [Type] message).
2450 Affected file is lib/silcutil/silclog.c.
2452 * Added two options to the config file, in the logging section:
2453 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2454 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2456 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2458 * Do not print the warning about log files not being initialized
2459 more than once to avoid excess logging. Affected file is
2460 lib/silcutil/silclog.c.
2462 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2463 the SIM copying in make install in Makefile.am.pre.
2465 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2467 * Rewritten silclog APIs. Globally interesting changes follows:
2468 silc_log_set_files() changed to silc_log_set_file().
2469 silc_log_set_callbacks() changed to silc_log_set_callback().
2470 ROBOdoc documented silclog header file.
2471 SilcLogCb now returns bool to wether inihibit the default
2472 handler or not (to keep the old behaviour return always TRUE).
2473 The new APIs should also fix the problem of the
2474 silcd_error.log file that was written in the current directory.
2477 Log files streams will remain opened after silc_log_set_file()
2478 call, means less CPU usage notably on high traffic servers.
2479 File streams are now full buffered, and flushed to the disk
2480 every 5 minutes, lesses HD activity and CPU usage.
2481 Messages can be redirected, allowing admins to configure
2482 one single logfile for all server messages.
2483 the silc_log_quick global variable to activate fast-logging.
2484 Affected files lib/silcutil/silclog.[ch]
2486 * Changed some code to conform new silclog APIs. Affected
2487 files are doc/example_silcd.conf.in, silcd/server.c
2488 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2491 * Fixed a memory leak that could occur in some situations.
2492 Affected file silcd/serverconfig.c.
2494 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2496 * Added the silc_client_del_client to remove the client from
2497 all channels as well. Affected file lib/silcclient/idlist.c.
2499 * Fixed the client library to correctly remove the client
2500 from all channels when the client entry is being destroyed.
2501 Affected file lib/silcclient/client_notify.c, command.c.
2503 * Added auto-nicking support to the client library. If the
2504 applicatio now sets client->nickname it will be sent to the
2505 server after connecting by the library. This way for example
2506 SILCNICK (or IRCNICK) environment variables will have effect
2507 and always change the nickname automatically to whatever
2508 it is wanted. Affected file lib/silcclient/client.[ch].
2510 * Renamed silc_server_command_bad_chars to the
2511 silc_server_name_bad_chars and moved it to the
2512 silcd/server_util.[ch]. Added also new function
2513 silc_server_name_modify_bad to return nickname that
2514 includes bad characters as new nickname without those
2515 bad characters. This check and modify is now used in
2516 silc_server_new_client when the username is initially set
2517 as nickname, so it must be checked to be valid nickname.
2518 Affected file silcd/packet_receive.c.
2520 * The nickname length is now taken from the packet for real
2521 and not trusted to strlen() since it clearly can return
2522 wrong length for nickname including bad characters. This
2523 also applies to channel names. Affected file silcd/command.c.
2525 * Removed the lib/silcsilm/modules directory. Modules are now
2526 compiled into the lib/silcsim. Fixed the copying of the
2527 modules to follow symbolic links in Makefile.am.pre.
2529 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2531 * Fixed silc_string_regexify list creation. Fixes bugs with
2532 BAN and INVITE commands in server. The affected file is
2533 lib/silcutil/unix/silcunixutil.c.
2535 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Removed the command destructor entirely from the server's
2538 command and command reply routines. It is not needed, and
2539 its usage was buggy and caused crashes. Affected files are
2540 silcd/command[_reply].[ch].
2542 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Cancel protocol and NULL sock->protocol if timeout
2545 occurred during protocol. Affected file silcd/server.c.
2547 * Cancel protocol timeouts always before calling the final
2548 callback, to assure that after final callback is called
2549 no other state will be called for the protocol anymore.
2550 Affected file silcd/protocol.c.
2552 * Print error log if incoming connection configuration could
2553 not be found. Affected file silcd/server.c.
2555 * Fixed JOIN command to correctly save the founder mode
2556 to the client on normal SILC server, when the channel
2557 was created by the router. Affected file silcd/command.c.
2559 * Fixed LIST command (hopefully) to send correct reply
2560 packets. Affected file silcd/command.c.
2562 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * The silc_packet_receive_process now returns FALSE if the
2565 read data was invalid packet, and TRUE if it was ok.
2567 The server now checks that if unauthenticated connection
2568 sends data and its processing fails the server will close
2569 the connection since it could be a malicious flooder.
2571 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2573 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Make sure the warning about error opening a log file is
2576 printed only once and not everytime it fails (produces
2577 too much useless log). Affected file lib/silcutil/silclog.c.
2579 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2581 * Made the silc_server_daemonise() function more readable.
2582 Affected file silcd/server.c.
2584 * Pid file is now optional, the user may comment it out from
2585 the config file. Removed define SILC_SERVER_PID_FILE, we
2586 don't need a default any longer. Affected file
2587 configure.in.pre, lib/Makefile.am.pre.
2589 * Make some use of the pid file. The server now dies at startup
2590 if it detects a valid pid file on his path. The server would
2591 die anyway in this circumstance, because of the bind() failure.
2592 Affected file silcd/silcd.c.
2594 * No longer compiling lib/dotconf.
2596 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Fixed JOIN command parsing not to crash. Affected file
2599 lib/silcclient/command.c.
2601 * Fied the NICK_CHANGE notify to add the new client entry
2602 even it is resolved. This removes an <[unknown]> nick
2603 thingy bug in the client. Affected file is
2604 lib/silcclient/client_notify.c.
2606 * Do not try to allocate 0 bytes (efence does not like it)
2607 in lib/silccore/silccomand.c when encoding payload.
2609 * Do not take IRCNICK as nickname in Irssi SILC client since
2610 it is not possible to set nickname before hand connecting
2611 the server (TODO has an entry about adding auto-nicking
2614 * Changed the silc_server_command_pending to check whether
2615 there already exists an pending entry with the specified
2616 command, command identifier and pending callback. This is
2617 to fix IDENTIFY and WHOIS related crashes that may register
2618 multiple pending commands with same identifier. Affected
2619 file silcd/command.c.
2621 * Fixed the server to reconnect to the router even if it
2622 was already reconnecting and EOF was received. This to
2623 fix a possibility that the server wouldn't ever try to
2624 auto-reconnect to the router. Affected file silcd/server.c.
2626 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * Fixed the server's password authentication to use the
2629 length of the locally saved password, and not the one
2630 sent in the packet. Affected file silcd/protocol.c.
2632 * Fixed same password authentication problem in the
2633 Authentication Payload handling routines in
2634 lib/silccore/silcauth.c.
2636 * Yet another password authentication problem fixed with
2637 channel password handling in silcd/command.c.
2639 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * If first character of string in silc_parse_userfqdn is '@'
2642 then do not parse it. Affected file is
2643 lib/silcutil/silcutil.c.
2645 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Fixed minor bug in IDENTIFY command reply sending, which
2648 caused various weird problems during JOIN when it was
2649 resolving names for users. Affected file silcd/command.c.
2651 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Fixed the IDENTIFY command reply sending to chech better valid
2654 clients. It was possible to send incomplete list of replies.
2655 Affected file silcd/command.c.
2657 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * Added silc_client_command[s]_[un]register functions now to
2660 dynamically register the commands in client library. Removed
2661 the static table of commands. This allows the client library
2662 to call commands without causing the application to know about
2663 what commands library has called.
2665 Removed the INFO command reply kludge to detect when the command
2666 was called by library. Now library use its own command reply
2667 function for INFO command.
2669 Added function silc_client_command_call to call a command.
2670 Application can use it to call command, not access the structure
2673 Now all commands that are sent by the client library (not
2674 explicitly sent by application) use own command reply functions.
2676 Affected files around lib/silcclient/ and in
2677 irssi/src/silc/core/.
2679 * Fixed the WHOIS command reply sending to chech better valid
2680 clients. It was possible to send incomplete list of replies.
2682 Fixed the WHOIS and IDENTIFY to send the request to router
2683 if normal server did not do it and did not find any results.
2685 Affected file silcd/command.c.
2687 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * Moved the internal data from SilcClient context into its
2690 own file, not accesible to application. Affected files
2691 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2692 and other files in client library.
2694 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Added doc/examples installation target in Makefile.am.pre.
2699 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2701 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2702 commands the found client entry will be removed from the
2703 cache, after notifying application about the error. Affected
2704 file lib/silcclient/command_reply.c.
2706 * Changed the /MSG to check for exact nickname user gave, and
2707 not let `nick' match `nick@host' if it is only one found. Now,
2708 user must type the exact nickname (like nick@host2) even if
2709 there are no more than one same nicks found. This is to avoid
2710 a possibility of sending nickname to wrong nickname since
2711 `nick' could match `nick@host'. Affected file is
2712 irssi/src/core/silc-servers.c.
2714 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Do not print "you are now server operator" or similar when
2717 giving /away command. Affected files are
2718 irssi/src/silc/core/client_ops.c, silc-servers.h.
2720 * Made the silc_server_command_pending_error_check to send
2721 the same command reply payload it received back to the
2722 original sender of the command. This way all arguments
2723 that was received by the server will be received by the
2724 client too. Affected file silcd/command.c.
2726 * Added the silc_idcache_add to return the created cache entry
2727 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2729 * Add global clients to expire if they are not on any channel.
2730 This is because normal server will never know if they signoff
2731 if they are not on any channel. The cache expiry will take
2732 case of these entries. This is done by normal servers only.
2733 The affected files are silcd/command_reply.c,
2734 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2736 * If server receives invalid ID notification for WHOIS or
2737 IDENTIFY and the ID exists in the lists, it is removed.
2738 Affected file silcd/command_reply.c.
2740 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2741 in client then client entry that it matches is searched and
2742 the nickname is printed on the screen for user. Affected
2743 file irssi/src/silc/core/client_ops.c.
2745 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Use cache entry expire time in the LIST command reply to
2748 purge old entries from the cache after the LIST command
2749 reply has been received. This way we don't have non-existent
2750 entries in the cache for too long. Affected file is
2751 silcd/command_reply.c.
2753 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * If we are normal server, and we've not resolved client info
2756 in WHOIS or IDENTIFY from router, and it is global client,
2757 we'll check whether it is on some channel. If it is not
2758 then we cannot be sure about its validity and will resolve it
2759 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2760 file silcd/command.c.
2762 * Search channel by name (if possible) rather than by ID
2763 in IDENTIFY command's command reply. Affected file is
2764 silcd/command_reply.c.
2766 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2768 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2769 Updated specs and implemented it. Affected file silcd/command.c,
2770 silcd/packet_send.c and silcd/packet_receive.c.
2772 * Implemented the <founder auth> payload handling in the JOIN
2773 command. If provided all conditions for channel joining
2774 except requirement to provide correct passphrase can be
2775 overrided by the channel founder. Updated the protocol specs.
2776 Affected file silcd/command.c.
2778 Added support for founder auth in JOIN command in client
2779 library. Fixed the parsing of the JOIN command now to support
2780 all options as they should be. The affected file is
2781 lib/silcclient/command.c.
2783 * Optimized the WHOIS and IDENTIFY commands to send the request
2784 to router only if it includes nicknames or other names. If
2785 they include only IDs then check the local cache first before
2786 routing. Affected file is silcd/command.c.
2788 * Added channels topic announcements. Affected file is
2789 silcd/packet_receive.c and silcd/server.c.
2791 * Fixed the silc_server_send_notify_topic_set to really destine
2792 the packet to channel. Affected file silcd/packet_send.c.
2794 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2795 library. Affected file lib/silcclient/client_notify.c.
2797 * Added UMODE announcements. Affected file silcd/server.c.
2799 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2801 * Memory leak fixes in:
2803 lib/silcutil/silcsockconn.c
2804 lib/silcske/silcske.c
2805 lib/silcske/groups.c
2807 lib/silccrypt/silcpkcs.c
2808 lib/silccore/silccommand.c
2809 lib/silccore/silcidcache.c
2814 * ROBOdoc documented the lib/silcske/groups.h file and a
2815 bit changed the interface for better.
2817 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2819 * Update the client entry context in the ID cache after
2820 nick change. Affected file lib/silcclient/command.c.
2821 Fixes the CUMODE command when regaining founder privileges,
2822 and a little WHOIS problem.
2824 * Fixed silc_net_gethostbyname to correctly call the
2825 inet_ntop. Affected file lib/silcutil/silcnet.c.
2827 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2829 * Added IPv6 support checking to the configure.in.pre, added
2830 also --enable-ipv6 option to override the check. Affected
2831 file configure.in.pre.
2833 * The silc_thread_create now calls the start function
2834 directly if threads support is not compiled in. Removes
2835 ugly #ifdef's from generic code. Affected files are
2836 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2838 * Added silc_net_gethostby[name/addr]_async to asynchronously
2839 resolve. Affected files are lib/silcutil/silcnet.[ch].
2841 * Added support for rendering IPv6 based server, client and
2842 channel IDs. Affected file lib/silcutil/silcutil.c.
2844 * Added support for creating IPv6 based server IDs. Affected
2845 file is silcd/serverid.c.
2847 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2849 * Added silc_net_gethostby[addr/name] into the
2850 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2851 routines. Added silc_net_is_ip[4/6]. Affected file is
2852 lib/silcutil/unix/silcunixnet.c. All routines that take
2853 address as argument now supports both IPv4 and IPv6 addresses.
2855 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2857 * Fixed LIST command reply sending in server. Affected file
2860 * Server now sends the kicker's client ID in the KICK notify
2861 to the kicked client. Affected file silcd/command.c.
2863 * The client library now parses the kickers client ID and
2864 UI displays it. Affected files lib/silcclient/client_notify.c
2865 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2867 * Made all payload parsing function prototypes consistent.
2868 They all take now const unsigned char * and uint32 pair as
2869 the payload data instead of SilcBuffer. Changes all around
2870 the source tree. Other unsigned char* -> const unsigned char*
2871 changes around the tree as well.
2873 * Optimized SFTP client and server packet sending not to
2874 allocate new buffer for each packet but to recycle the
2875 first allocated buffer. Affected files are
2876 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2878 * Optimized the SFTP client to use SilcList instead of
2879 SilcDList for requests, because it is faster. Affected file
2880 is lib/silcsftp/sftp_client.c.
2882 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2883 into lib/silccore/silcid.[ch].
2885 Renamed silcpayload.[ch] into silcargument.[ch].
2887 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * If client entry is deleted with active key agreement
2890 session, abort the session.
2892 The silc_client_abort_key_agreement now calls the completion
2893 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2895 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2898 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Don't use __restrict in older GCC's. Affected file is
2901 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2903 * silc_net_localhost now attempts to reverse lookup the
2904 IP/hostname. Affected file lib/silcutil/silcnet.c.
2906 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2907 command. It can be used to gain founder privileges at
2908 the same time when joining the channel.
2910 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2911 kicker's client ID as well. Updated protocol specs.
2913 Defined that the server must send SILC_COMMAND_IDENTIFY
2914 command reply with error status to client who sent
2915 private message with invalid client ID.
2917 Updated the protocol specification.
2919 * Added silc_server_send_command_reply to send any
2920 command reply. Affected file silcd/packet_send.[ch].
2922 * Added silc_id_payload_encode_data to encode ID payload
2923 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2925 * The server now send IDENTIFY command reply with error
2926 status if client ID in private message is invalid. Affected
2927 file silcd/packet_receive.c.
2929 * Save the server key file with server's IP address in
2930 the filename instead of hostname. The affected file is
2931 irssi/src/silc/core/client_ops.c.
2933 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2938 * Added libtool support for compiling shared objects in
2939 lib/silcsim. Affected file configure.in.pre and
2940 lib/silcsim/Makefile.am. Original patch by cras.
2942 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Pid file configuration, and server's config file fixes
2945 patch by toma. Updated CREDITS file.
2947 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * Fixed silc_client_channel_message to not try to decrypt
2950 the message twice if it resolved the destination client
2951 information. This could cause of dropping one channel
2952 message. Affected file lib/silcclient/client_channel.c.
2954 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2956 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2957 lib/silcclient/client.c. This function is used when the SILC
2958 Client is run under some other scheduler, or event loop or
2959 main loop. On GUI applications, for example this may be
2960 desired to used to run the client under the GUI application's
2961 main loop. Typically the GUI application would register an
2962 idle task that calls this function multiple times in a second
2963 to quickly process the SILC specific data.
2965 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2967 * Fixed silc_server_drop() for dropping the supplementary
2968 groups as well, this could cause a security hole on some
2971 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2976 * Write PID file after dropping privileges. Added -F option
2977 to run server on foreground. A patch by debolaz.
2978 Affected files silcd/server.c, silcd/silcd.c.
2980 * Fixed MOTD to return the MOTD file server name. Affected
2981 file silcd/command.c.
2983 * Added INFO command reply handling to the Irssi SILC Client.
2984 Affected file irssi/src/silc/core/client_ops.c.
2986 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Fixed the silc_idcache_list_* routines to really support
2989 the dynamic list. Fixes a crash. Affected file is
2990 lib/silccore/silcidcache.c.
2992 * Fixed the LIST command reply to really call LIST command's
2993 pending callbacks. Affected file silcd/command_reply.c.
2995 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Update conn->local_entry->nickname after giving NICK
2998 command. Affected file lib/silcclient/command.c.
3000 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3002 * Added the [pid] option to the silcd configuration file
3004 Affected files: serverconfig.[ch] and silcd.c
3006 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Save fingerprint in WHOIS command reply in server.
3009 Affected file silcd/command_reply.c.
3011 * Fixed NICK commands pending callback registration.
3012 Affected file lib/silcclient/command.c.
3014 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Use ++server->cmd_ident when sending commands in server,
3017 instead of random number. Affected file silcd/command.c.
3019 * Fixed GETKEY command reply to call actually GETKEY pending
3020 command callbacks. Affected file silcd/command_reply.c.
3022 * A bit stricter check for nicknames. Check for same nickname
3023 in NICK command also. Affected file silcd/command.c.
3025 * Do not call INFO command everytime client ID changes, only
3026 during first connecting. Affected file lib/silcclient/client.c.
3028 * Set the new nickname only after successful command reply for
3029 NICK command is returned by server. Affected file
3030 lib/silcclient/command.c.
3032 * Remove nicknames from nicklist during server_signoff notify.
3033 Should fix /NAMES bit more. The affected file is
3034 irssi/src/silc/core/silc-channels.c.
3036 * Added `fingerprint' field to the SilcIDListData in the
3037 silcd/idlist.h to hold the fingerprint of the client's
3040 Send the fingerprint of the client's public key in WHOIS
3043 Affected files silcd/command.c, and silcd/idlist.[ch].
3045 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3046 create fingerprint from given data.
3048 * Show the fingerprint of the client's public key in WHOIS.
3049 Affected files irssi/src/module-formats.[ch] and
3050 irssi/src/silc/core/client_ops.c.
3052 * Format the multiple same nicknames also during JOIN and
3053 NICK_CHANGE notifys. Affected file is
3054 lib/silcclient/client_notify.c.
3056 * Do not print error on screen for invalid private message
3057 payload since it can come if someone is sending private
3058 messages with wrong key. Affected file
3059 lib/silccore/silcprivate.c.
3061 * Fixed multiple concurrent /PING crash. Affected file
3062 lib/silcclient/command.c.
3064 * Changed the wrong ID encoding. All IP addresses must be
3065 in MSB first order in encoded format. They were encoded
3066 wrong and was in LSB format. Affected files are
3067 silcd/serverid.c, lib/silcutil/silcutil.c.
3069 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3071 * Call the `connect' client operation through the scheduler
3072 in case of error. Affected file lib/silcclient/client.c.
3074 * Call the `failure' client operation even if the error
3075 occurred locally during a protocol. Affected file is
3076 lib/silcclient/protocol.c.
3078 * Added support of sending LIST command to router from normal
3079 server. This way normal server can get list of all channels
3080 in the network too. Fixed the channel list sending in the
3081 server too. Affected files are silcd/command.c, and
3082 silcd/command_reply.[ch].
3084 * Added silc_server_update_channels_by_server and
3085 silc_server_remove_channels_by_server. They are used during
3086 disconnection of primary router and in backup router protocol.
3087 Affected file silcd/server_util.[ch], silcd/server.c and
3088 silcd/server_backup.c.
3090 * Fixed channel adding to global list in IDENTIFY command
3091 reply in server. Affected file silcd/command_reply.c.
3093 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * If the incoming packet type is REKEY or REKEY_DONE process
3096 that packet always synchronously. Fixes yet another MAC
3097 failed error on slow (dialup) connections. Affected file
3098 lib/silcclient/client.c and silcd/server.c.
3100 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Call check_version SKE callback for initiator too. Affected
3103 file lib/silcske/silcske.c.
3105 * Implemented fix for security hole found in the SKE that was
3106 fixed in the specification few days back; the initiator's
3107 public key is now added to the HASH value computation.
3108 Added backwards support for the old way of doing it too, for
3109 old clients and old servers. Affected file is
3110 lib/silcske/silcske.c.
3112 * Enabled mutual authentication by default in SKE. If initiator
3113 is not providing mutual authentication the responder will
3114 force it. This will provide the proof of posession of the
3115 private key for responder. The affected files are
3116 lib/silcclient/protocol.c and silcd/protocol.c.
3118 * Do not cache anymore the server's public key during SKE.
3119 We do mutual authentication so the proof of posession of
3120 private key is done, and if the server is authenticated in
3121 conn auth protocol with public key we must have the public
3122 key already. Affected file silcd/protocol.c.
3124 * Added new global debug variable: silc_debug_hexdump. If
3125 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3126 file lib/silcutil/silclog.[ch].
3128 * Fixed compilation warning due to char * -> const char *.
3129 Affected files lib/silcutil/silcnet.h, and
3130 lib/silccore/silcauth.[ch].
3132 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Fixed CMODE command when new channel key was created. If
3135 the creation failed the old key was removed. Next time giving
3136 same command would crash the server since the old key was
3137 freed already. Affected file silcd/command.c.
3139 * Fixed the silc_server_announce_get_channels to not crash
3140 on reconnect. Affected file silcd/server.c.
3142 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Added silc_log_set_debug_string function to set a regex
3145 string to match for debug output. Only the function names,
3146 or filenames matching the given debug string is actually
3147 printed. This way it is possible to filter out those debug
3148 strings that user is not interested in.
3150 Fixed a bug in silc_string_regexify.
3152 Affected files lib/silcutil/silclog.[ch], and
3153 lib/silcutil/unix/silcunixutil.c.
3155 * Changed the -d options in both server and Irssi SILC client
3156 to take the debug string as argument. Affected files
3157 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3159 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * Added silc_hash_babbleprint to create a Bubble Babble
3162 Encoded fingerprint. The encoding is developed by Antti
3163 Huima (draft-huima-babble-01.txt), and it creates human
3164 readable strings out of binary data. Affected file
3165 lib/silccrypt/silchash.[ch].
3167 * Print the babble print now in addition of fingerprint as well
3168 in Irssi SILC client. Affected files are
3169 irssi/src/fe-common/silc/module-formats.[ch],
3170 irssi/src/fe-common/silc/core/client_ops.c.
3172 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Fixed a security problem found in SKE. The initiator's
3175 public key too is now added to the HASH hash value creation
3176 which is signed by the responder to create the SIGN value.
3177 This will prevent anyone in the middle to lie to the responder
3178 about the initiator's public key. If this is done now, the
3179 man in the middle will get caught. Updated the protocol
3182 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Better installation directory handling. Configure module
3185 paths and other paths automatically to example_silc* files
3186 in doc/. A patch by toma.
3188 * Fixed compiler warning from MPI library, and from SILC RNG.
3191 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3192 It can be configured with ./configure. A patch by toma.
3194 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3196 * Find correct make to use in prepare-clean. A patch by
3197 toma. Affected file prepare-clean.

3216 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3218 * Added silc_pkcs_public_key_compare to compare two
3219 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3221 * Check that the client who set the founder mode on the
3222 channel is the same client that is giving the founder
3223 mode to itself. It is done by comparing the saved public
3224 key (it is saved even in the authentication is passphrase).
3225 Affected file silcd/command.c.

3232 * Process the DISCONNECT packet through scheduler in the
3233 client library. Affected file lib/silcclient/client.c.
3235 * Fixed the silc_client_packet_parse to not to increase
3236 the packet sequence number if the conn->sock and the
3237 current socket connection is not same. This can happen
3238 for example during key agreement when the conn includes
3239 multiple socket connections (listeners). Affected file
3240 lib/silcclient/client.c.
3242 * The sender of the file transfer request now provides also
3243 the pointer (listener) for the key exchange protocol. If
3244 the listener cannot be created then it sends empty key
3245 agreement and lets the receiver provide the listener.
3247 Added `local_ip' and `local_port' arguments to the
3248 silc_client_file_send. If they are provided they are used,
3249 if not then it will attempt to find local IP address, if
3250 not found or bind fails then the remote client will provide
3253 Affected files are lib/silcclient/client_ftp.c and
3254 lib/silcclient/silcapi.h.
3256 * Extended the FILE SEND command to support defining the
3257 local IP and port for key exchange listener. They are
3258 optional. Affected file irssi/src/silc/core/silc-servers.c.
3260 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * Defined to WHOIS command reply the sending of fingerprint
3263 of the client's public key (if the proof of posession of the
3264 corresponding private key is verified by the server).
3265 Updated to the protocol specification.
3267 * Added support of receiving the client's public key's
3268 fingerprint in command reply in client library. Affected
3269 file is lib/silcclient/command_reply.c, and
3270 lib/silcclient/idlist.[ch].
3272 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3293 removing from ID cache.
3295 Affected file is lib/silcclient/client_ftp.c.
3297 * Fixed silc_net_addr2bin to return correct address. Affected
3298 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3300 * Fixed file transfer session removing on signoff notify.
3301 Affected file irssi/src/silc/core/silc-servers.c.
3303 * Added the SilcClientFileError to be returned in the monitor
3304 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.

3325 client library. Affected file lib/silcclient/client_prvmsg.c.
3327 * Do not actually remove the client directly from ID cache
3328 during SERVER_SIGNOFF, but invalidate it. This way we
3329 preserve the WHOWAS info for the client. Affected file
3330 silcd/server_util.c.
3332 * Fixed SERVER_SIGNOFF notify handling in the server. The
3333 server is now able to process incoming SERVER_SIGNOFF notify
3334 for a server that it doesn't even know about. It will remove
3335 the clients provided in the notify. Affected file
3336 silcd/packet_receive.c.
3338 * Check for partial packet in data queue after every packet that
3339 was found from the queue. Return and wait for more data if
3340 there is partial data in queue. Affected file is
3341 lib/silccore/silcpacket.c.
3343 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * Added SilcClietFileError enum to indicate error in
3346 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

3351 * Check that newsize in silc_buffer_realloc is larger than
3352 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3354 * Added better monitor of file transfers. It now monitors
3355 key agreement protocol during the file transfer too. Added
3356 error reporting too. Affected files
3357 irssi/src/silc/core/silc-servers.c,
3358 irssi/src/fe-common/silc/module-formats.[ch].
3360 * Wrote a help file for FILE command.
3362 * Added silc_rng_global_get_byte_fast to get not-so-secure
3363 random data as fast as possible. Random data is read from
3364 /dev/urandom if available and from the SILC RNG if not
3365 available. It is used in padding generation. Affected file
3366 lib/silccrypt/silcrng.[ch].
3368 * All packets in client library are now processed synchronously.
3369 Optimized packet processing a lot. Affected file
3370 lib/silcclient/client.c.
3372 * All server connection packets are processing synchronously
3373 now in server, to optimize packet processing. Affected file
3376 * Include files are installed now only in Toolkit distribution
3377 if make install is given. Affected files: all Makefile.am's.
3379 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Assure that silc_client_notify_by_server_resolve does not
3382 resolve the client information multiple times. If it cannot
3383 be found by the first it cannot be found at all. Affected
3384 file lib/silcclient/client_notify.c.
3386 * Fixed WHOWAS command reply calling. Affected file
3387 lib/silcclient/command_reply.c.
3389 * Removed all references to silc_idlist_get_client from the
3390 Irssi SILC client since that call is internal call used by
3391 the library. The Irssi SILC client will use now client
3392 retrieval functions found in silcapi.h.
3394 * Fixed a bug in resolving nickname info before sending
3395 private message. It used freed memory. Affected file
3396 irssi/src/silc/core/silc-servers.c.

3417 * Added silc_net_localip to return local host's IP address.
3418 Affected file lib/silcutil/silcnet.[ch].
3420 * If key exchange or rekey protocol is active for a connection
3421 parse all packets syncronously since there might be packets
3422 in packet queue that we are not able to process without first
3423 processing packets before them. Affected file silcd/server,
3424 lib/silcclient/client.c.
3426 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3427 whether library should continue processing the packet.
3428 Affected file lib/silccore/silcpacket.h.
3430 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3474 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3475 is incomplete and is being resolved, it won't be resolved
3478 Make sure also that USERS command reply does not resolve
3479 twice information. Affected file is
3480 lib/silcclient/command_reply.c.
3482 Make sure that silc_client_get_clients_by_list does not
3483 resolve twice same information.
3485 * Check for valid client->id in the silc_server_free_client_data.
3486 Affected file silcd/server.c.
3488 * Fixed /GETKEY nick@server not to crash if the server entry
3489 is not found. Affected file lib/silcclient/command.c.
3491 * Fixed the silc_server_check_cmode_rights to check the
3492 requested modes correctly. Affected file silcd/command.c.

3499 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Call the silc_server_udpate_servers_by_server in the
3502 primary router that comes back online in the backup resuming
3503 protocol. Otherwise it routes packets wrong. Affected file
3504 silcd/server_util.[ch], silcd/server_backup.c.
3506 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3509 lib/silcutil/silcbuffmt.[ch].
3511 * Redefined the SILC packet header to include the padding
3512 length. Affected file lib/silccore/silcpacket.[ch].
3514 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3515 length for maximum padding up to 128 bytes). Affected
3516 file lib/silccore/silcpacket.h.
3518 * Removed all backwards support for old 0.5.x MAC thingies.
3519 The SILC packet header change makes it impossible to be
3520 backwards compatible.
3522 * Send the ENDING packet with timeout in the backup resuming
3523 protocol. This is to assure that all routers has connected
3524 to the primary router. Affected file silcd/server_backup.c.
3526 * Changed the RNG to take the first IV from random data. It
3527 used to take it from zero actually. Changed the RNG also
3528 to use /dev/urandom during session. /dev/random is used
3529 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3531 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Changed the SILC packet header to have the first two bytes
3534 (the packet length) encrypted. Affected files aroung the
3535 code tree, lib/silccore/silcpacket.[ch]. Removed the
3536 SilcPacketCheckDecrypt callback. It is not needed anymore
3537 since the silc_packet_receive_process will determine now
3538 whether the packet is normal or special.
3540 * Implemented the unidirectional MAC keys. Affected files
3541 lib/silcske/silcske.c, silcd/protocol.c and
3542 lib/silcclient/protocol.c.

3549 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Allow backup router to announce servers. All servers
3552 announced by backup router are added to the global list
3553 automatically. Update hte server's socket to our primary
3554 router also when backup router announces a server.
3555 Affected file silcd/packet_receive.c.
3557 * Do not update the client->router in the function
3558 silc_server_udpate_clients_by_server if the client is on
3559 global list. We might fail to find any specific server
3560 for locally connected clients and local cell clients. They
3561 should still use the `from' and not `to' as client->router.
3562 This fixes backup router resuming protocol. Affected file
3563 silcd/server_util.c.
3565 * Decrease channel statistics count only if the channel
3566 deletion worked. Affected files are silcd/server.c and
3567 silcd/server_util.c.
3569 * Added silc_server_update_servers_by_server to update origin
3570 of all server entries. Used during backup router protocol.
3571 Affected files silcd/server_util.[ch], silcd/server.c. and
3572 silcd/backup_router.c.
3574 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new

3576 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3577 lib/silccrypt/silchmac.c.
3579 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3581 * Assure that router cannot reroute the same channel message
3582 to the sender. Affected file silcd/packet_receive.c.
3584 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Made better checks that the channel message is not sent
3587 to the router it came from. Affected file is
3588 silcd/packet_send.c. Fixed memory leak too.
3590 * Announce informations for incoming router connection, but
3591 only after checking if it is replaced by backup router.
3592 Affected file silcd/packet_receive.c.
3594 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * Fixed the backup resuming protocol to work in multiple
3597 router environment. Affected file silcd/server_backup.c.
3599 * Route packet only to one router in the function
3600 silc_server_packet_send_to_channel. Affected file is
3601 silcd/packet_send.c.
3603 * Fixed silc_server_send_notify_dest to set the broadcast
3604 flag. Fixed the silc_server_send_notify_topic to actually
3605 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3606 Affected file silcd/packet_send.c.
3608 * Changed the SFTP Filesystem interface. Changed the
3609 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3610 the filesystem operation function. The SilcSFTPFilesystem
3611 is now a context that is allocated by all filesystem allocation
3612 functions and it already includes the operations structure
3613 and filesystem specific context. It is given as argument
3614 now to the silc_sftp_server_start. This made the interface
3615 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3616 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3618 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3620 * Changed the backup router adding and getting interfaces
3621 in the server. The router that will be replaced by the
3622 specified backup router is now sent as argument. Affected
3623 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3626 * Added silc_net_addr2bin_ne to return the binary form of
3627 the IP address in network byte order. Affected files
3628 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3630 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3632 * Check for existing server ID in silc_server_new_server
3633 and in silc_server_connect_to_router_final and remove the
3634 old entry if it exists. Affected file silcd/packet_receive.c,
3637 * Send the channel message always to only one router, either
3638 in upstream or downstream. Affected file is
3639 silcd/packet_send.c.
3641 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3643 * Wrote the definition of the backup resuming protocol to the
3644 protocol specification.
3646 * Removed one redundant channel key generation from normal
3647 server during joining procedure. Removed one redundant
3648 channel key sending from server to router during joining
3649 procedure. Affected file silcd/command.c.
3651 * Made minor bugfixes to the backup router resuming protocol.
3652 Affected file silcd/server_backup.c, server.c.
3654 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3657 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3660 * Implemented the backup resuming protocol that is used to
3661 resume the primary router position in the cell after the
3662 primary router comes back online. Affected files
3663 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3664 and silcd/server_util.[ch].
3666 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3668 * Sleep two (2) seconds after sending QUIT command to server.
3669 Affected file lib/silcclient/command.c.
3671 * Assure that if outgoing data buffer is pending do not force
3672 send any data. Affected file silcd/packet_send.c.
3674 * Assure that if outgoing data buffer is pending do not force
3675 send any data. Affected file lib/silcclient/client.c.
3677 * Implemented the backup router support when the primary router
3678 goes down. The servers and routers can now use the backup
3679 router as new primary router without loosing connectivity.
3681 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3684 in the server to indicate disabled entry. All data read
3685 from the connection will be ignored and no data is sent
3686 for entry that is disabled. Affected files are
3687 silcd/idlist.h, silcd/server.c.
3689 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Created SFTP client and server test programs in the
3692 lib/silcsftp/tests directory.
3694 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * Implemented memory filesystem (virtual filesystem) for
3697 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3700 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * Implemented the SFTP (SSH File Transfer Protocol) to the
3703 lib/silcsftp. It includes SFTP client and SFTP server
3706 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Moved lib/silccore/silcprotocol.[ch] to the
3709 lib/silcutil library.
3711 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3712 take variable argument list pointer as argument. Affected
3713 file lib/silcutil/silcbuffmt.[ch].
3715 * Added silc_buffer_set function that is used to set data
3716 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3717 Affected file lib/silcutil/silcbuffer.h.
3719 * Changed various routines in the core library to use the new
3720 silc_buffer_set instead of allocating new buffer only for
3723 * Added 64-bit value formatting and unformatting support to the
3724 silc_buffer_[un]format routines. Affected file is
3725 lib/silcutil/silcbuffmt.[ch].
3727 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3728 to includes/bitmove.h.
3730 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3732 * Fixed channel user mode saving in client library. Affected
3733 file lib/silcclient/command[_reply].c.
3735 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3737 * Defined the file transfer to the SILC Protocol. Added
3738 new packet type SILC_PACKET_FTP and defined File Transfer
3739 Payload. The mandatory file transfer protocol is SFTP
3740 (SSH File Transfer Protocol). Affected file in addition
3741 of the internet draft is lib/silccore/silcpacket.h.
3743 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3744 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3745 is used as part of backup router protocol when the primary
3746 router of the cell is back online and wishes to resume
3747 the position as primary router.
3749 * Redefined the MAC generation keys in the protocol. The
3750 same key is not used anymore in both direction. Both
3751 direction will now use different keys for sending and
3752 receiving. This fixes a potential security flaw. This
3753 change causes incompatibilities in the protocol.
3755 * Redefined also the MAC computation from the packet.
3756 An packet sequence number is now added to the MAC
3757 computation. This prevents possible replay attacks against
3758 the protocol. This change too causes incompatibilities
3761 Added `sequence' field to the SilcPacketContext to hold
3762 the current sequence number for the packet.
3764 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3766 * Added `created' field to the SilcIDListData in the file
3767 silcd/idlist.h to indicate the time when the entry was
3770 * Added `created' field to the SilcChannelEntry too. Affected
3771 file silcd/idlist.h.
3773 * Added `creation_time' aguments to all the announcement functions
3774 in the server. If it is provided then only the entries that
3775 was created after the provided time frame are actually
3776 announced. Affected file silcd/server.[ch].
3778 * The protocol says that the Channel ID's IP address must be
3779 based on the router's IP address. Added check for this in
3780 the silc_server_new_channel when processing incoming New Channel
3781 Payload. Affected file silcd/packet_receive.c.
3783 * Print out the correct version with --version in SILC client.
3784 Affected file irssi/src/silc/core/silc-core.c.
3786 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3788 * Fixed WHOWAS command to check for completnes of the client
3789 entry always, not just when the command is coming from client.
3790 Affected file silcd/command.c.
3792 * Added new function silc_server_packet_queue_purge to purge the
3793 outgoing data queue to the network. After the function returns
3794 it is guaranteed that the outgoing packet queue is empty.
3795 Affected file silcd/packet_send.[ch].
3797 * Purge the outgoing packet queue in the rekey protocol's final
3798 callback to assure that all rekey packets go to the network
3799 before quitting the protocol. Affected file silcd/server.c.
3801 * Added silc_client_packet_queue_parse as similar function as
3802 in server to the client library. The affected file is
3803 lib/silcclient/client.c.
3805 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3807 * Splitted silcd/server.c and created silcd/server_util.[ch]
3808 for utility functions.
3810 * Added new socket flag SILC_SF_DISABLED to indicate that the
3811 connection is open but nothing can be sent to or received from
3812 the connection. Affected file lib/silcutil/silsockconn.[ch].
3813 The checking for disabled socket is checked in the low level
3814 silc_socket_write and silc_socket_read functions.
3816 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Allow only nicknames and channel names that fits into the
3819 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3821 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * When processing JOIN command reply in server check that if
3824 the channel exists in our global list we'll move it the local
3825 list. Affected file silcd/command_reply.c.
3827 * Fixed the check whether client is joined on the channel already
3828 in JOIN command. Affected file lib/silcclient/command.c.
3830 * Fixed the JOIN command reply to check whether the channel
3831 already exists. Affected file lib/silcclient/command_reply.c.
3833 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Added silc_ske_status_string to map the SKE error numbers
3836 to readable strings. The affected files are
3837 lib/silcske/silcske[_status].[ch].
3839 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3841 * Do not show the private channels on the WHOIS channel list
3842 as it is not allowed by the protocol. The affected file is
3845 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3847 * Assure that the packet length digged from the actual packet
3848 is something sensible in the silc_packet_decrypt_rest_special
3849 in lib/silccrypt/silcpacket.c.
3851 * Free and NULL the allocated pointer in silc_hmac_alloc if
3852 the HMAC allocation fails. The affected file is
3853 lib/silccrypt/silchmac.c.
3855 * Print the selected security properties to the log files in
3856 the server. Affected file silcd/protocol.c.
3858 * Add SKE's reference counter even if calling the completion
3859 callback manually. Otherwise it goes negative, although it
3860 does not cause any problems. The affected file is
3861 lib/silcske/silcske.c.
3863 * Remove the client entry with short timeout after giving the
3864 KILL command. Affected file lib/silcclient/command.c.
3866 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3867 case all found clients are already disconnected (WHOWAS would
3868 found them) in the server. Affected file silcd/command.c.
3870 * Update the last_receive (time of last data received) to be
3871 updated only when received private or channel message so that
3872 the idle time showed in WHOIS makes more sense.
3874 * Added boolean field `valid' in to the SilcClientEntry in the
3875 client library to indicate whether the entry is valid or not.
3876 This fixes the nickname change bug on channel when changing
3877 the nickname to be same than the old (like nick to Nick) the
3878 nickname formatter doesn't set the new nick anymore to Nick@host.
3879 Affected file lib/silcclient/idlist.[ch].
3881 * Now actually fixed the nickname changing on disconnection.
3882 Added new function silc_change_nick to the Irssi SILC Client.
3883 Affected file irssi/src/silc/core/client_ops.c,
3884 irssi/src/silc/core/silc-nicklist.[ch].
3886 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3888 * Check that the public key exists in the GETKEY command before
3889 trying to encode it. Affected file silcd/command.c.
3891 * Print some notifications on received public keys with GETKEY
3892 command in the Irssi SILC Client. Affected files are
3893 irssi/src/fe-common/silc/module-formats.[ch],
3894 irssi/src/silc/core/client_ops.c.
3896 * Use IDENTIFY command to resolve the server information in the
3897 GETKEY command instead of INFO command. Affected file
3898 lib/silcclient/command.c.
3900 * All command reply functions in the client library now calls
3901 the pending command reply callbacks even if an error has
3902 occurred. The server has done this a long time and now it was
3903 time to move the client library to this as well. Now all
3904 errors can be delivered back to the pending command reply
3905 callbacks if necessary. Affected files are
3906 lib/silcclient/command[_reply].[ch].
3908 * Change the nickname on disconnection back to the username
3909 because in reconnect the server will enforce it to it anyway.
3910 Affected file irssi/src/silc/core/silc-servers.c.
3912 * Fixed a config file parsing bug in the Irssi SILC client.
3913 Affected file irssi/src/silc/core/clientconfig.c.
3915 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3917 * When printing the channel mode on JOIN, verify that the
3918 channel key and channel's HMAC are valid. Affected file
3919 irssi/src/silc/core/client_ops.c.
3921 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3923 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3924 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3925 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3927 * Removed channel key rekey task deleting from the function
3928 silc_server_save_channel_key. Affected file silcd/server.c.
3929 Added explicit timeout task context instead that is used to
3930 delete the task if we are registering a new task before the
3931 new task has elapsed.
3933 * When channel key rekey occurs the client library now saves
3934 the old channel key for a short period of time (10 seconds) and
3935 is able to use it in case some is still sending channel
3936 messages encrypted with the old key after the rekey. Affected
3937 file lib/silcclient/[idlist.h|client_channel.c].
3939 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3941 * Added check to the silc_server_new_id_real to not accept
3942 new ID if it is the sender's own ID. Affected file is
3943 silcd/packet_receive.c.
3945 * Assure that we do not announce ourself or the one we've
3946 sending our announcements when we're router and are announcing
3947 servers to our primary router. Affected file silcd/server.c.
3949 * Fixed silc_server_command_identify_check_client to assemble
3950 correct WHOIS packet. It send corrupted WHOIS packet and
3951 caused problem with router to router connections. Affected
3952 file silcd/command.c.
3954 Fixed also silc_server_command_whois_check the same way
3955 as for the IDENTIFY command.
3957 * Added new SilcIDListStatus to the server in the SilcIDListData
3958 structure. The status now includes the current status of
3959 the entry (like registered, resolved etc.). Affected file
3960 silcd/idlist.[ch]. Defined a bunch of different status types
3961 as well. This replaced the old boolean registered field as well.
3963 Added resolve_cmd_ident field to the SilcClientEntry structure
3964 too so that if the entry is for example being resolved so
3965 another command may attach to the same pending command reply
3966 without requiring to resolve the same entry again. This concept
3967 should optimize the WHOIS and the IDENTIFY resolving under
3968 heavy load by taking away unnecessary resolving for entries
3969 that are being resolved already.
3971 Added support for adding multiple pending commands for one
3972 command idenfier. Affected file silcd/command[_reply].[ch].
3974 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3975 before deleting the data. Otherwise the hash table will have
3976 freed data in comparison functions. Affected file is
3977 silcd/command_reply.c.
3979 * Fixed silc_idlist_replace_client_id to add the new entry to
3980 the cache with NULL nickname. Otherwise there will be invalid
3981 memory as the nickname after the nickname is freed. Affected
3982 file silcd/packet_receive.c.
3984 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3985 saved into wrong slots because the previous number of entries
3986 was not taken into account. Affected file silcd/idlist.c.
3987 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3989 * If we are router and we receive JOIN notify to a channel that
3990 does not have any users then notified client is marked as the
3991 channel founder, as it is it. The affected file is
3992 silcd/packet_receive.c
3994 * Added to the extended hash table API's table_del_*ext functions
3995 the destructor as argument too, so that the caller can decide
3996 which destructor to use or whether to use destructor at all.
3997 Affected file lib/silcutil/silchashtable.[ch].
3999 * Fixed ID Cache purging. It actually deleted the entries from
4000 the hash table after the data was freed. The hash table ended
4001 up comparing freed memory. The affected file is
4002 lib/silccore/silcidcache.c.
4004 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4006 * Fixed Irssi SILC client's KILL command's HELP syntax.
4008 * The USERS command now resolves the detailed user information
4009 if the userinfo field is missing. Affected file is
4010 lib/silcclient/command_reply.c.
4012 * Do not print error in silc_file_read if the read file does
4013 not exist. Just silently return NULL. Affected file is
4014 lib/silcutil/silcutil.c.
4016 * Fixed the silc_log_output to not wine about NULL filename
4017 and to not create some bogus " " filename. Affected file is
4018 lib/silcutil/silclog.c.
4020 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4022 * Fixed various printing bugs on the user interface in the
4023 Irssi SILC Client. Minor changes that were forgotten from
4026 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4028 * Fixed the configure.in.pre and the compilation and distribution
4029 environment to support the new autoconf 2.52. That version is
4030 now required to compile the CVS trunk.
4032 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4034 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4035 to generally parse user@fqdn format strings. Affected file
4036 lib/silcutil/silcutil.c.
4038 * Added nickname_format and nickname_force_format fields to the
4039 SilcClientParams structure. The first one defines the format
4040 for the nicknames that the library will enforce if the receives
4041 multiple same nicknames. The second one is boolean value and
4042 can be used to force the library to always enforce the format
4043 to the nicknames regardles whether there are multiple nicknames
4044 or not. This configurable formatting was employed to flexibly
4045 support accessing multiple nicknames from the user interface.
4046 The userinterface can now set the nicknames to what ever format
4047 they prefer. Affected file lib/silcclient/silcapi.h.
4049 Added function silc_client_nickname_format to the file
4050 lib/silcclient/idlist.c. It performs the nickname formatting.
4052 Added new field `hostname´ to the SilcClientEntry context.
4053 It holds the hostname of the client. Affected file is
4054 lib/silcclient/idlist.h.
4056 * Irssi SILC Client sets the nicknames in nick@hostn format.
4057 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4058 irssi/src/silc/core/silc-core.c.
4060 The WHOIS printing now also shows both the real nickname and
4061 the formatted nickname so that user knows how to access the
4062 user if there are multiple same nicknames cached. Affected
4063 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4064 printing formatting too to take the hostname now as a separate
4065 argument. The Affected file is
4066 irssi/src/fe-common/silc/modules-formats.[ch].
4068 * Changed the silc_client_get_clients_local to accept the formatted
4069 nickname as argument. It accepts the real nickname too but the
4070 formatted nickname can be used to find the true entry from
4071 multiple entries. Affected file lib/silcclient/silcapi.h and
4072 lib/silcclient/idlist.c.
4074 * Added nickname_format_parse field to the SilcClientParams.
4075 It is a callback function provided by the application to parse
4076 the nickname out of the formatted nickname string. The library
4077 calls it to get the nickname from the formatted string. Since
4078 the application generally knows better the format of the nickname
4079 string it parses it instead of the library, even though library
4080 encodes the formatted string. If the callback function is not
4081 provided then the library will use the string as is. The
4082 affected file is lib/silcclient/silcapi.h.
4084 * All the nickname strings passed to the client library in
4085 commands are now expected to be formatted nickname strings.
4086 If the command does not support the formatted nickname string
4087 it will assume that the sent string is the actual nickname.
4088 Affected file lib/silcclient/command.c.
4090 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4092 * Added public key authentication support to OPER and SILCOPER
4093 commands in the client library. Affected file is
4094 lib/silcclient/command.c.
4096 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4098 * Changed the get_auth_methdod client operation to be asynchronous.
4099 It can be async if the application resolves the authentication
4100 method from the server during the negotiation. Added new
4101 SilcGetAuthMeth completion callback that the application will
4102 call after resolving the authentication method.
4104 Added function silc_client_request_authentication_method that
4105 the application can use to resolve the authentication method
4106 from the server. Added also SilcConnectionAuthRequest callback
4107 that the library will call after the server has replied. The
4108 application can call this function if it does not know the
4109 current authentication method.
4111 Affected files are lib/silcclient/client.c and
4112 lib/silcclient/silcapi.h.
4114 * The Irssi SILC client now automatically resolves the authentication
4115 method incase any configuration information is not present (and
4116 currently there never is). The affected file is
4117 irssi/src/silc/core/client_ops.c.
4119 * Fixed public key authentication from the client library.
4120 Affected file lib/silcclient/protocol.c. Changed also the
4121 protocol specification about the public key authentication in
4122 the connection authentication protocol. The actual data to be
4123 signed is now computed with a hash function before signing.
4125 * Fixed the public key authentication from the server as well.
4126 Affected file silcd/protocol.c.
4128 * Removed the mlock()'s from the memory allocation routines.
4129 Affected file lib/silcutil/silcmemory.c. The ./configure does
4130 not check anymore for the mlock(). Affected file is
4133 * Fixed USERS command in server to allow the execution of the
4134 command for private and secret channels if the client sending
4135 the command is on the channel. Affected file silcd/command.c.
4137 * Fixed silc_client_get_clients_local to return the clients
4138 count correctly. It could return wrong value. Affected file
4139 lib/silcclient/idlist.c.
4141 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4143 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4144 types. The assembler optimizations seemed not to like 64-bit
4145 data types. The assmebler optimizations thus are now enabled
4146 also for BSD systems as opposed to only enable them for Linux.
4148 * Do not check for threads at all on BSD systems. Affected
4149 file configure.in.pre.
4151 * Removed -n and -h options from the Irssi SILC Client since
4152 they are not used in silc.
4154 * Fixed the prime generation to assure that the first digit
4155 of the generated random number is not zero since our conversion
4156 routines does not like number strings that starts with zero
4157 digit. If zero digit is seen the random number is regenerated.
4158 This caused some corrupted RSA keys when the zero first digit
4159 was met. Affected file lib/silcmath/silcprimegen.c.
4161 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4163 * Fixed WIN32 configuration in the ./configure script.
4164 Fixed to include xti.h on environments that has it.
4165 Patches by Carsten Ilchmann and andrew.
4167 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4169 * Changed the silc_id_create_client_id to be collision
4170 resistant. It is now assured that there cannot be created
4171 two same client ID's. I suspect that some weird bugs in
4172 the server were actually caused by duplicate Client IDs.
4173 Affected file silcd/serverid.[ch]. A router receiving
4174 new ID now also assures and informs the sending server
4175 if the ID caused collision.
4177 * Changed the silc_id_create_channel_id to also assure that
4178 there are no collisions.
4180 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * Statement about ignoring the Mutual Authentication flag when
4183 performing rekey with PFS was a bit misleading. It is ignored
4184 if it was set in the initial negotiation, it cannot be even
4185 set in the rekey. Fixed in the ke-auth draft. Started the
4186 new versions of the protocol drafts in the doc/.
4188 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4190 * Fixed a bug in silc_client_command_identify_save when saving
4191 new channel information. The channel name was no duplicated
4192 and caused crash on exit. Affected file is
4193 lib/silcclient/command_reply.c.
4195 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4197 * Fixed the getkey command handling in the server. Send just
4198 empty OK reply to the sender if the key could not be fetched
4199 (but everything else was ok, like the key just was not available).
4200 Changed the public key parameter to optional in the protocol
4201 specs so that empty OK reply can be sent. Affected file
4204 Added a message to Irssi SILC client to tell to user if the
4205 server did not return a public key.
4207 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4209 * Fixed a channel key regeneration bug. It registered new
4210 timeout tasks exponentially until all system resources were
4211 used. Affected file silcd/server.c.
4213 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4215 * Added the SILC Document generator to the scripts/silcdoc.
4216 It can be used to generate the Toolkit Reference Manual out
4217 of the source tree. Internally it will also use the RoboDoc
4218 generator now imported in util/robodoc.
4220 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4222 * Added couple of return's in rekey protocol if error orccurred
4223 during the protocol. The execution must be terminated.
4224 Affected file silcd/protocol.c. Also, terminate the protocol
4225 always with timeout.
4227 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4229 * The client's Client ID was created initally from the wrong
4230 nickname (it could have been in format nick@host) in the
4231 silc_server_new_client. Affected file silcd/packet_receive.c
4233 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4235 * Added some SILC_LOG_ERROR's to various error conditions
4236 if client could not be added to ID cache. Affected files
4237 silcd/packet_receive.c and silcd/server.c.
4239 * When client's sock->user_data is freed, NULL also the
4240 client->router and client->connection pointers. Added check
4241 for these pointers being NULL to various places around the
4242 code. Affected file silcd/server.c.
4244 * Added client->data.registered == TRUE checks to various
4245 places around the code to assure that unregistered client's
4246 are not handled when it is not allowed. Affected file
4249 * Added `bool registered' fields to all
4250 silc_idlist_[server|client]_get_* routines to indicate whether
4251 the fetched client needs to be registered or not. Affected
4252 file silcd/idlist.[ch].
4254 * Add your own entry as registered to the ID cache in the
4255 server. Affected file server.c.
4257 * Fixed a bug in silc_server_new_server. The SilcServer was
4258 set as the new server's context instead of SilcServerEntry.
4259 This naturally caused some weird bugs.
4261 * Added "updated" field the SilcChannelEntry which indicates
4262 the time since the channel entry was last accessed. This
4263 can be used to determine whether it is necessary to
4264 announce the channel after backup resuming protocol.
4265 Affected files silcd/idlist.[ch].
4267 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4269 * Do not delete the channel rekey task when adding it
4270 for in silc_server_create_channel_key.
4272 * Changed the silc_server_create_channel_key to return
4273 TRUE or FALSE to indicate the success of the channel key
4276 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4278 * Fixed MSVC++ project files and added missing files to

4281 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4283 * Do not add TCP_NODELAY flag if the operating system
4284 does not have it defined. Affected files are
4285 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4287 * Fixed buffer overflow from Irssi SILC Client. Affected
4288 file irssi/src/fe-common/core/themes.c.
4290 * Fixed double free in client library in the file
4291 lib/silcclient/client.c when disconnecting from server.
4293 * Applied double free patch from cras to Irssi SILC client.
4294 Affected files irssi/src/core/[modules/expandos].c
4296 * Fixed the disconnection handling to Irssi SILC Client.
4297 The application must call silc_client_close_connection
4298 in ops->connect client operation in case of failure of
4299 the connection. Affected file is
4300 irssi/src/silc/core/client_ops.c.
4302 * Do not set sock->protocol to NULL in the function
4303 silc_client_close_connection after executing the protocol's
4304 final callback since the sock might not be valid anymore.
4305 Affected file lib/silcclient/client.c.
4307 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4309 * Do not enable SILC_THREADS if the linking with libpthread
4310 did not happen. Affected file configure.in.pre.
4312 * Added notion to protocol specification that server must
4313 verify the sent authentication payload with CMODE when
4314 setting the channel founder key. Implemented it to the
4315 server. Affected file silcd/command.c.
4317 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4319 * Added _EXTRA_DIST SILC distribution variable to the
4320 distributions file. It is used to conditionally add extra
4321 files or directories to the specific distribution. Affected
4322 files ./prepare, Makefile.am.pre and distributions.
4324 Removed the `_' from the start of the distribution names.
4327 * Added README.WIN32 for instructions to compile the Toolkit
4330 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4332 * Fixed a double free in disconnection in the server. Affected
4333 file is silcd/server.c.
4335 * Fixed the lib/silcske/groups.c to work now also with GMP
4336 MP library. The string conversion did not work when using
4337 specific base and the base is indicated in the string as well.
4339 * Created win32/ directory which now includes MSVC++ specific
4340 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4341 It will appear only in the toolkit distribution
4343 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4345 * Changed the key material distribution function in case when
4346 the hash output is too short. The data is now concatenated
4347 a bit differently than it used to. Made the change to the
4348 SKE protocol specification.
4350 * Added better GMP detection to configure.in.pre. A patch
4353 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4355 * Fixed a minor bug in SKE that might cause some problem on
4356 some platforms. Affected file lib/silcske/silcske.c.
4358 * Added the cookie checking for initiator in the SKE. It checks
4359 that the responder returns the sent cookie unmodified. The
4360 affected file is lib/silcske/silcske.c. Added new SKE
4361 error type INVALID_COOKIE that can be sent during the
4362 negotiation. Fixed some memory leaks as well.
4364 * Added the "invalid cookie" error message to Irssi SILC client's
4367 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4369 * Added `task_max' field to the SilcClientParams to indicate
4370 the maximum tasks the scheduler can handle. If set to zero,
4371 default values are used. Affected file lib/silcclient/silcapi.h.
4373 * Fixed memory leaks in silc_client_close_connection. Affected
4374 file lib/silcclient/client.c.
4376 * Added silc_client_del_client_entry to client library to free
4377 all memory of given client entry. Affected file is
4378 lib/silcclient/idlist.[ch].
4380 * Added new functions silc_client_del_channel and
4381 silc_client_del_server to delete channel and server entries.
4382 Affected file lib/silcclient/[silcapi.h/idlist.c].
4384 * Removed silc_client_del_client_by_id from silcapi.h.
4386 * Fixed the INFO command to return the server's own info
4387 correctly when querying by Server ID. Affected file is
4390 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4392 * Removed the non-blocking settings in WIN32 code in the
4393 silc_sock_[read/write] and added SleepEx instead. Affected
4394 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4395 of input data is now checked with FIONREAD and ioctlsocket.
4397 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4399 * Call silc_schedule_task_del_by_context in the
4400 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4401 Affected file lib/silccore/silcprotocol.c.
4403 * Call silc_protocol_cancel for active protocols in the
4404 silc_server_close_connection if the funtion
4405 silc_server_free_sock_user_data has not been called.
4406 Affected file silcd/server.c.
4408 * Generic tasks cannot be deleted using the del_by_fd
4409 task deleting function since generic tasks does not match
4410 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4412 * Added a notion to SILCOPER help file that the SILCOPER works
4413 only on router server, not on normal server.
4415 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4417 * Added for WIN32 support for the new scheduler as well.
4418 Affected file lib/silcutil/win32/silcwin32schedule.c.
4420 * Fixed the SHA1 implementation to work on various platforms.
4422 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4424 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4425 API. It is part of the scheduler now. Everything else is
4426 as previously but some functions has changed their names.
4427 Checkout the lib/silcutil/silcschedule.h for the interface.
4428 Updated all applications to use the new interface. Affected
4429 files are lib/silcutil/silcschedule.[ch].
4431 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4433 * Found a bug in the SKE implementation. The HASH value,
4434 specified by the protocol, was not computed correctly. The
4435 public key of the responder was not added to the computation
4436 even though it is mandatory. Affected file lib/silcske/silcske.c.
4437 This unfortunately causes incompatibilities with older
4438 clients and servers.
4440 * Added WIN32 specific network init and uninit functions:
4441 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4442 the Winsock2. Affected file lib/silcutil/silcnet.h and
4443 lib/silcutil/win32/silcwin32net.c.
4445 * Set the socket always to nonblocking mode on WIN32 after
4446 reading data or writing data. Affected file is
4447 lib/silcutil/win32/silcwin32sockconn.c.
4449 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4451 * Fixed various compilation problems under WIN32. Affected
4452 files lib/silcutil/win32/silcwin32thread.c and
4453 lib/silcutil/win32/silcwin32schedule.c.
4455 * Removed all _internal.h #includes from public header
4456 files. Internal headers must never be included from
4459 Removed also the lib/silcske/payload_internal.h file.
4461 * All include files that may be needed (public and some others
4462 included by the public headers) by application developers are
4463 now copied to the ./includes directory. It does not copy any
4464 internal headers. Affected file Makefile.defines.pre and all
4465 Makefile.am's under lib/ and subdirs.
4467 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4469 * Do not change the ~/.silc directory's permissions automatically.
4470 Affected file irssi/src/silc/core/clientutil.c.
4472 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4474 * Do not cancel the protocol in silc_server_close_connection
4475 it might cause recursion. Now cancelled in the function
4476 silc_server_free_sock_user_data. Affected file silcd/server.c.
4478 * Fixed the silc_server_remove_clients_by_server to regenerate
4479 the channel keys correctly finally. Added also new function
4480 silc_server_remove_clients_channels to actually do it.
4481 Affected file silcd/server.c.
4483 * Fixed the silc_server_new_channel to not crash by giving
4484 wrong router to the new channel. Affected file is
4485 silcd/packet_receive.c.
4487 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4489 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4490 which is given as argument to the silc_client_alloc now.
4491 It can be used to configure the client and set various parameters
4492 that affect the function of the client.
4494 * The USERS command in server did not check whether the channel
4495 is private or secret. Affected file silcd/command.c.
4497 * Added new argument to the USERS command in protocol specification.
4498 The USERS command now can take the channel name as argument
4499 as well. Added support for this in client and server and
4500 updated the protocol specs.
4502 * Completed the GETKEY command in client. It can be now used
4503 to fetch also servers public key not only some clients.
4504 Affected files lib/silcclient/command[_reply].c.
4506 * Added silc_client_get_server to return server entry by the
4507 server name. Affected files lib/silcclient/silcapi.h and
4510 * Redefined the IDENTIFY command in protocol specification to be
4511 more generic. It now can be used to query information about
4512 any entity in the SILC Network, including clients, servers and
4513 channels. The query may be based either the entity's name
4514 or the ID. Added support for this in both client and server.
4516 Affected files silcd/command.c and lib/silcclient/command.c
4517 and command_reply.c.
4519 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4520 the _from_client and _from_server functions. Affected file
4523 * Added silc_client_get_channel_by_id_resolve to the file
4524 lib/silcclient/silcapi.h to resolve channel information by
4525 its ID. Added also silc_client_get_channel_by_id that
4526 does not resolve it from the server.
4528 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4530 * Added SilcServerEntry context into the client library
4531 to represent one server. The INFO command now allocates
4532 these to save the resolved server info. For now on the
4533 client library will also keep information about servers,
4534 connected and resolved with INFO.
4536 The INFO command now allocates the SilcServerEntry context
4537 and saves the server info there. The COMMAND_REPLY in
4538 the INFO now returns the parameters to application in
4539 same order as defined in the protocol specification.
4541 The entries are cached in the client->server_cache.
4543 * The INFO command is now issued after received the Client ID
4544 from the server. Affected file lib/silcclient/client.c.
4546 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4547 to the application as the mode changer might be server.
4548 It is guaranteed that NULL is not returned anymore to the
4549 application. Affected file lib/silcclient/client_notify.c.
4551 The ID Type is now also passed to the application so that
4552 it can check whether the returned entry is SilcClientEntry
4555 Added new function silc_client_get_server_by_id to return
4556 the server entry by ID. Affected files are the
4557 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4559 * Do not create the channel in the Irssi SILC Client when issuing
4560 the JOIN command but when received the sucessful JOIN command
4561 reply. Otherwise the channel might get created even though we
4562 could not join it. The Affected file is
4563 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4565 * Fixed a channel joining bug in router. The router must also
4566 check the channel modes, invite and ban lists etc. when serving
4567 the JOIN command sent by normal server. Affected file is
4568 silcd/command.c. The router now resolves the client's
4569 information from the server who sent the JOIN command if it
4570 does not know it, and processes the JOIN command only after
4573 * Changed the SilcCommandCb to take new argument; void *context2.
4574 Affected file lib/silccore/silccommand.h
4576 The second argument in the command callbacks in the server now
4577 includes the SilcServerCommandReplyContext if the command was
4578 called as pending command callback from the command reply.
4579 Otherwise it is NULL. When called as pending the status of the
4580 command reply will be checked and if it was erronous the
4581 error will be sent to the original sender of the command.
4582 This way the client always receives the error messages even
4583 though the server was actually the one who received the error
4584 when it resent the command to router, for example. Affected
4585 files silcd/command[_reply].[ch].
4587 * Fixed sending WHOWAS command's error message to client if
4588 the requested client could not be found. It was missing.
4591 * Changed the CMODE and CUMODE commands reply arguments in the
4592 protocol specification. The Channel ID is now sent in both
4593 of the commands to identify the channel. Implemented this
4594 new feature to the client and server. Affected files
4595 lib/silcclient/command_reply.c and silcd/command.c.
4597 * Made better checks for invite and ban lists in the JOIN
4598 command in server. Affected file silcd/command.c.
4600 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4602 * The server now performs the incoming host IP/DNS lookup
4603 using the silc_socket_host_lookup and thus does not block
4604 the server anymore. Affected file silcd/server.c.
4606 * Completed the multi-thread support for SILC Scheduler in
4607 the lib/silcutil/silcschedule.c.
4609 * Fixed the configure.in.pre to detect the pthread correctly
4612 * Fixed a deadlock in silc_task_queue_wakeup in the file
4613 lib/silcutil/silctask.c.
4615 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4617 * Added new function silc_schedule_wakeup that is used in
4618 multi-threaded environment to wakeup the main thread's
4619 schduler. It needs to be used when a thread adds a new task
4620 or removes a task from task queues. After waking up, the
4621 scheduler will detect the task queue changes. If threads
4622 support is not compiled in this function has no effect.
4623 Implemented the wakeup mechanism to both Unix and WIN32
4624 systems. Affected files are lib/silcutil/silcschedule.[ch],
4625 lib/silcutil/unix/silcunixschedule.c and the
4626 lib/silcutil/win32/silcwin32schedule.c.
4628 * Added new function silc_task_queue_wakeup to wakeup the
4629 scheduler by the specified task queue. Affected file
4630 lib/silcutil/silctask.[ch].
4632 * The silc_socket_host_lookup_start now wakes up the scheduler
4633 after adding the timeout task. Affected file is
4634 lib/silcutil/silcsockconn.c.
4636 * The silc_socket_host_lookup is synchronous now if the threads
4637 support is not compiled in. However, the callback is still
4638 called asyncronously through the scheduler, anyway. Affected
4639 file lib/silcutil/silcsockconn.c.
4641 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4643 * Added new function silc_socket_host_lookup to perform
4644 asynchronous IP and FQDN lookups for the socket connection.
4645 Affected files lib/silcutil/silcsockconn.[ch].
4647 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4649 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4650 that may or may not compile the mutex support in.
4652 Changed the silc_mutex_alloc interface. It allocates the
4653 mutex now to the sent pointer and returns TRUE or FALSE.
4655 Affected file lib/silcutil/silcmutex.h.
4657 * Wrote the SILC Task Queue interface to support multi-threads.
4658 Affected file lib/silcutil/silctask.[ch].
4660 * Wrote the SILC Scheduler to support multi-threads. Affected
4661 file lib/silcutil/silcschedule.c.
4663 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4665 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4666 in lib/silcutil/win32/.
4668 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4670 * Defined SILC Mutex API and SILC Thread API and implemented
4671 them for Unix. Affected files are
4672 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4673 lib/silcutil/unix/silcunixmutex.c and
4674 lib/silcutil/unix/silcunixthread.c.
4676 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4678 * Fixed the silc_server_remove_clients_by_server's channel
4679 key re-generation. The hash table handling was incorrect
4680 and would not work with many channels. Affected file is
4683 * Fixed some memory leaks around the server code.
4685 * Rewrote the silc_server_get_users_on_channel to support IPv6
4686 based Client ID's. Affected file silcd/server.c.
4688 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4689 specification. However, a separate document must be written
4690 to define the detailed signing procedure and the payload
4691 associated with the flag. Defined the flag to the
4692 lib/silccore/silcchannel.h as well.
4694 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4696 * Changed the dynamic tables to static size tables in the
4697 lib/silccrypt/silchmac.c.
4699 * Removed GCC dependencies from the code. A patch by cras.
4701 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4703 * Do not show the error "Error receiving packet bla bla"
4704 in server if it really was not an error (-2 means that reading
4705 is pending). Affected file silcd/server.c.
4707 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4709 * Fixed a possible crash in silc_server_remove_clients_by_server
4710 in silcd/server.c. Fixed there also some memory leaks.
4712 * Fixed the silc_idlist_replace_client_id. It could replace
4713 wrong key in the hash table. Affected file silcd/idlist.c.
4715 * Do not check whether there are global users on the channel
4716 if the channel->global_users is FALSE. Affected functions
4717 silc_server_remove_from_one_channel and
4718 silc_server_remove_from_channels in silcd/server.c. Also,
4719 do not check if the removed client is local as we can be
4720 sure that global client was not removed from the channel
4721 and checking for global users is not needed.
4723 * The silc_server_remove_clients_by_server now re-generates
4724 the channel keys correctly for those channels that had
4725 clients removed from them. Affected file silcd/server.c.
4727 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4729 * Found the reason of random crashes in the server. We weren't
4730 ignoring the SIGPIPE signal (which can be sent in write())
4731 and it crashed the server. Affected file silcd/silcd.c.
4733 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4735 * Assure that sock->user_data is not NULL in the function
4736 silc_server_packet_send in silcd/packet_send.c.
4738 * Disconnect the remote connection if it could not be added
4739 to any ID lists in the server. The affected file is
4742 * Check in silc_server_packet_send[_real/dest] that the
4743 socket is not disconnecting and ignore the data if it is.
4744 Affected file silcd/packet_send.c.
4746 * Define inline to __inline on native WIN32 compilation.
4747 Affected file includes/silcwin32.h.
4749 * Added some explicit type casts for inline code since MSVC
4750 require them. Affected files lib/silcutil/silcbuffer.h,
4751 lib/trq/silcdlist.h and lib/trq/silclist.h.
4753 * Print warning in log files from now on if the packet
4754 decryption fails. Affected file silcd/server.c.
4756 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4758 * Changed the `say' client operation's interface to accept
4759 new `type' argument to indicate the type of the message sent
4760 by the library. The application may filter the library's
4761 messages according the type. The affected file is the
4762 lib/silcclient/silcapi.h.
4764 * Added two new functions to lib/silcclient/silcapi.h:
4765 silc_client_del_client and silc_client_del_client_by_id.
4766 Affected file lib/silcclient/idlist.c.
4768 * Moved the clientincludes.h from includes/ to silc/ and
4769 serverincludes.h from includes/ to silcd/.
4771 * The modes for the CMODE and CUMODE are now passed as
4772 uint32 for application with COMMAND_REPLY. The affected
4773 file is lib/silcclient/command_reply.c.
4775 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4777 * /WHOIS without arguments shows client's own information.
4778 Affected file lib/silcclient/command.c.
4780 * Changed PING to not accept any arguments. The specs
4781 says that client can ping only the connected server so
4782 requiring an argument is not needed. Affected file is
4783 lib/silcclient/command.c.
4785 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4787 * Fixed a fatal bug in private message sending and reception
4788 encryption and decryption when using private message keys.
4789 The implementation was incorrect and did not follow the
4790 specification. It causd that some of the message were
4791 lost since it did not use the sending and receiving keys
4792 as the protocol suggests. This has been fixed and will cause
4793 incompatibilities with older clients when sending private
4794 message encrypted with private message keys. Affected files
4795 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4796 and various other in Irssi SILC Client.
4798 Added `responder' boolean argument to the functions
4799 silc_client_add_private_message_key[_ske] to indicate when
4800 the key is added as responder or initiator of the key
4803 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4805 * Removed the silc_ske_check_version function and created
4806 a SilcSKECheckVersion callback. Added also a function
4807 silc_ske_set_callbacks that is now used to set all SKE
4808 callbacks. The callback functions are not given to
4809 the SKE functions anymore, but this function is used to
4812 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4814 * Added `silc_version' argument to the silc_client_alloc
4815 to define the version of the application for the library.
4816 The library will use the version string to compare it
4817 against the remote host's (usually a server) version
4818 string. Affected file lib/silcclient/silcapi.h
4820 * Added the KE protocol context to Key Agreement context
4821 in client library so that we can abort the SKE if it
4822 is in process when we get timeout. Affected file is
4823 lib/silcclient/client_keyagr.c.
4825 * Do not resolve the client ID forever if it returns in the
4826 first time that such client does not exist. This was done
4827 for example with private message. Affected file is
4828 lib/silcclient/client_prvmsg.c.
4830 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4832 * Do not add regex.h for WIN32. The affected file
4833 includes/silcincludes.h.
4835 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4836 not work yet 100%. It generates the DLL's automatically
4837 when compiling with --with-win32 under cygwin.
4839 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4841 * lib/contrib/regex.c is not compiled on WIN32.
4843 * Added silc_net_get_socket_opt function to the
4844 lib/silcutil/silcnet.h.
4846 * Added includes/silcwin32.h for WIN32 specific includes
4849 * Do not use ptime structure or any of the posix process
4850 functions on WIN32 in lib/silccrypt/silrng.c.
4852 * Added silc_gettimeofday to provide generic function
4853 for struct timeval on all platforms. Added the function
4854 to lib/silcutil/silcutil.h.
4856 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4858 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4859 library as they clearly belong there. As a plus side we
4860 can make the actual socket connection routines platform
4863 Added also new generic function silc_socket_read and
4864 silc_socket_write (that used to be silc_packet_[read/write].
4865 The implementation of these are platform specific.
4867 * Added WIN32 specific routines of silc_socket_[read/write]
4868 to lib/silcutil/win32/silcwin32sockconn.c.
4870 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4872 * Added preliminary support for native WIN32 compilation under
4873 cygwin (using the -mno-cygwin option for GCC) to the
4874 ./configure.in.pre. The --with-win32 now prepares the
4875 compilation for native WIN32.
4877 * Rewrote the SILC Scheduler interface in the file
4878 lib/silcutil/silcschedule.h. The scheduler is now context
4879 based and does not have anymore any global static scheduler.
4880 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4881 and created lib/silcutil/win32 directory for WIN32 based
4884 * Added Unix specific network routines to the
4885 lib/silcutil/unix/silcunixnet.c and the old
4886 lib/silcutil/silcnet.c includes now only generic routines.
4888 Added WIN32 specific network routines to the
4889 lib/silcutil/win32/silcwin32net.c.
4891 * Added Unix specific utility functions from the
4892 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4894 * Added WIN32 SILC Scheduler to the file
4895 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4898 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4900 * Do not handle JOIN notify in the server if the target client
4901 is not registered (idata->registered == FALSE). The affected
4902 file is silcd/packet_receive.c.
4904 * Update the nickrec->founder in event_cumode in the Irssi SILC
4905 client. Affected file irssi/src/silc/core/silc-channels.c.
4907 * Fixed the CUMODE_CHANGE notify handling in the server when
4908 server and router are announcing their clients on channels.
4909 Now the mode changes are saved and notified correctly. The
4910 affected file is /silcd/packet_receive.c.
4912 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4913 They really did not replace the cache entry in the ID Cache.
4914 Now they do that. Affected file silcd/idlist.c.
4916 * Fixed the KICK notify handling in the Irssi SILC client to
4917 update the channel records so that the kicked client does not
4918 appear to be on the channel. The affected file is
4919 irssi/src/silc/core/silc-channels.c.
4921 * Always update the conn->current_channel when executing command
4922 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4924 * Fixed the KILL notify handling in Irssi SILC client to remove
4925 the killed client on all channels.
4927 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Fixed the silc_parse_command_line to remove extra spaces
4930 from the start and end of the arguments. Affected file is
4931 lib/silcutil/silcutil.c.
4933 * Cancel and free any active protocol in the function
4934 silc_server_close_connection. Affected file silcd/server.c.
4936 * Cancel and free any active protocol in the function
4937 silc_client_close_connction. Affected file is
4938 lib/silcclient/client.c.
4940 * Do not execute the KILL command for clients that are in
4941 history (ie. they are not in the network). Affected file is
4944 * Fixed KILL notify handling, client does not crash anymore.
4945 Affected file irssi/src/silc/core/silc-channels.c.
4947 * Reduced the default packet buffer size from 2048 to 1024 in
4948 lib/silccore/silcpacket.c.
4950 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4951 counter to the SKE context that is incresed when the SKE library
4952 performs async operation outside the library. If the outside
4953 process frees the SKE context and FREED status will be set
4954 and the library will detect after the sync operation that the
4955 libary is freed. The affected files are
4956 lib/silcske/silcske[_status].[ch].
4958 * Resolve the client entry information in the function
4959 silc_client_channel_message to assure that NULL pointer is not
4960 passed as client entry to the application. */
4962 * Fixed the task timeout calculation to assure that there is
4963 never negative timeouts. The affected file is
4964 lib/silcutil/silcschedule.c.
4966 * Fixed the channel user mode notification sending in server.
4967 It was sent point-to-point to the router (or to server by router)
4968 but it needs to be destined to a channel. The routines now
4969 supports sending the channel user mode notifys to the channels
4970 when announcing clients and channels. Affected files are
4971 silcd/server.c and silcd/packet_receive.c.
4973 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4974 It did not actually replace the old channel entry in the cache.
4975 Affected file lib/silcclient/client_notify.c.
4977 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Fixed a possible crash in silc_packet_send_prepare. It now
4980 assures always that there is enough space in the buffer and
4981 at the tail area of the buffer (for MAC).
4983 Fixed the inbound buffer reallocation in silc_packet_read.
4984 It was old code and did not handle the reallocation correctly.
4987 The affected file is lib/silccore/silcpacket.c.
4989 * Fixed buffer overflow in silc_parse_nickname in the file
4990 lib/silcutil/silcutil.c.
4992 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * make install generates new server keys only if there is not
4997 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5000 Added check that if the NOREPLY is set then we will not send
5001 the away message. This avoids infinite loop of away messages
5002 if both clients are away. The affected file is
5003 lib/silcclient/client_prvmsg.c.
5005 * Fixed client crash if /NICK was given without arguments.
5006 Affected file lib/silcclient/command.c.
5008 * Server does not send the invite list in INVITE command back
5009 to the client if the list was not altered. Added this notion
5010 to the protocol spec as well. Affected file silcd/command.c.
5012 Fixed possible crash in INVITE command by checking the
5013 value of silc_server_get_client_route command.
5015 * Fixed the INVITE notify type handling. The arguments are now
5016 taken in correct order and client does not crash. The affected
5017 file is irssi/src/silc/core/silc-channels.c.
5019 Removed the "Inviting xxx to channel" message from the
5020 client library away and let the application handle it.
5021 Affected file lib/silcclient/command.c. Added that message
5022 to Irssi SILC client's message formats.
5024 * Fixed CMODE command crash in client. It now checks the
5025 amount of arguments correctly and does not crash. The affected
5026 file is lib/silcclient/command.c.
5028 * Do not create new channel automatically in silc_channels_join
5029 but check whether the channel by that name already exists.
5030 Affected file irssi/silc/core/silc-channels.c.
5032 * Do not send the SERVER_SIGNOFF to router if the disconnected
5033 entity was the router. Affected file silcd/server.c.
5035 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5036 SILC client as it was missing from there.
5038 Added the handling of the KICK notify to the Irssi SILC client
5039 as it was missing. Added "you have been kicked" message to
5040 Irssi SILC client's message modules formats.
5042 Added the handing of the KILL notify to the Irssi SILC client
5043 as it was missing. Added the kill message module formats
5046 The affected file is irssi/src/silc/core/silc-channels.c.
5048 * The router did not save the channel mode the server announced.
5049 Affected file silcd/packet_receive.c.
5051 * Fixed a possible crash in INFO command in server. If the
5052 server did not provide the server info it crashed. Affected
5053 file silcd/command.c.
5055 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Fixed the GETKEY command in the server to check also the
5058 global list. Otherwise the GETKEY would not work correctly
5059 in normal SILC server. Affected file silcd/command.c.
5061 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Fixed GETKEY crash, it crashed if the command did not succseed.
5065 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5068 is now real and not just an macro interface to GMP.
5070 Removed the entire GMP from the source tree and imported new
5071 NSS MPI library instead. Reason for removing GMP is that it is
5072 extremely large and compiles extremely slow. The NSS MPI
5073 is only a few files and compiles in less than 10 seconds.
5074 The speed is also about the same as GMP. The MPI is imported
5075 to lib/silcmath/mpi.
5077 If the system has GMP installed we will still use the GMP.
5078 If it is not then the NSS MPI will be compiled.
5080 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Merged a long nickname (127 characters long) crash bugfix from
5083 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5085 * Merged a freed memory reference bugfix from Irssi CVS tree.
5086 Affected file irssi/src/core/commands.c.
5088 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Added the server's public key sving and verification to the
5091 server when performing the SKE. This was missing and the
5092 remote server's (or router's) public key was accepted without
5093 checking whether we have it previously or trust it at all.
5094 Affected file silcd/protocol.c.
5096 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Check in the silc_server_timeout_remote if protocol is active
5099 and make sure that the protocol's final callback is called so
5100 that all memory if freed. Affected file silcd/server.c.
5102 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * silc_server_whois_send_reply crashed the server if the nickname
5105 was 127 characters long. Affected file silcd/command.c.
5107 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Added sanity check to the silc_server_new_client. If the hostname
5110 is provided inside username then check that the provided hostname
5111 really is the same as the resolved one. If the hostname was not
5112 resolved then check it from the public key. Affected file is
5113 silcd/packet_receive.c.
5115 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5116 if the server disconnected us and the connection is not valid
5117 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5119 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5120 the library to the lib/silcutil/silcutil.[ch].
5122 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Close log file after open. Affected file
5125 lib/silcutil/silclog.c.
5127 * Check whether sock == NULL in silc_client_send_packet and return
5128 if it is. Affected file lib/silcclient/silcclient.c.
5130 * Check rec->entry == NULL in the Irssi SILC Client before
5131 sending the channel message. Affecte file is
5132 irssi/src/silc/core/silc-servers.c.
5134 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Merged a splitted window bugfix from Irssi CVS tree. The
5137 affected file is irssi/src/fe-text/textbuffer-view.c.
5139 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5140 It did not print nickname.
5142 * Improved the distributions system a bit.
5144 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5147 irssi/src/fe-text/gui-window.c.
5149 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5150 to in-active server. The affected file is
5151 irssi/src/silc/core/client_ops.c.
5153 * Resolve the client in USERS command reply if the entry does
5154 not have username resolved. The affected file is
5155 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5156 command to WHOIS command to really resolve stuff. The USERS
5157 is not used any more in any critical section so WHOIS can
5158 be used even though it might be slower than IDENTIFY.
5160 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5163 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Changed the protocol API a bit more consistent in the
5166 lib/silccore/silcprotocol.[ch].
5168 * Changed the following headers to ROBODoc format:
5170 lib/silccore/silcpayload.h
5171 lib/silccore/silcprotocol.h
5172 lib/silccore/silcsockconn.h
5174 All core library headers are now formatted.
5176 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Fixed a bug in Irssi SILC client; do not show that you are
5179 server/router operator if you really are not. Affected file is
5180 irssi/src/silc/core/client_ops.c.
5182 * Renamed silc_command_free_payload to silc_command_payload_free.
5183 Affected file lib/silccore/silccommand.h
5185 * Added silcmath.h to include the prototoypes of various routines
5186 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5189 * Changed the following headers to ROBODoc format:
5191 lib/silccore/silcchannel.h
5192 lib/silccore/silccommand.h
5193 lib/silccore/silcid.h
5194 lib/silccore/silcidcache.h
5195 lib/silccore/silcmode.h
5196 lib/silccore/silcnotify.h
5197 lib/silccore/silcpacket.h
5198 lib/silcmath/silcmath.h
5200 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Added checking to the server code not to start the server if
5203 ciphers and stuff are not configured properly. Affected files
5204 silcd/serverconfig.[h] and silcd/server.c.
5206 * Changed the layout of the header files of the public interfaces
5207 in the SILC libraries. The new layout supports ROBODoc
5208 documentation tool (and some others) so that it is easy to create
5209 a library reference manual. All the other headers and source
5210 code must still follow the CodingStyle document. Also source
5211 code must not include these ROBODoc stuffs, only the headers.
5212 Furthermore, all public interface headers must now be named
5213 by using `silc' prefix, example: silcapi.h, silccipher.h.
5214 Some files were renamed due to this. All the other headers
5215 must not be used as public interfaces. I will update the
5216 CodingStyle document later. Changed following headers, so far:
5218 lib/silcclient/silcapi.h
5219 lib/silccore/silcauth.h
5220 lib/silccore/silcprivate.h
5221 lib/silccrypt/silcdh.h
5223 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Removed silc_client_packet_send_flush from the client library
5228 as it is not needed. Affected file lib/silcclient/client.[ch].
5230 * Added printing of message of unresolved authentication method
5231 to the Irssi SILC client. Added it to the module formats.
5232 Removed the same message from the client library.
5234 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added new distribution feature, DISTLABEL. Every distribution
5237 can define own preprocessor label that can be used in the
5238 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5239 file distributions, acconfig.h.pre and prepare.
5241 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added Makefile.defines_int to include the actual definitions
5244 for Makefile.defines.in. Tested the new distribution system,
5245 created distributions and tested installation.
5247 * Added AWAY message printing to the Irssi SILC client. Added
5248 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5250 * Added SCONNECT command to call the SILC's CONNECT command.
5251 Cannot use CONNECT directly since Irssi uses that internally.
5252 Affected file irssi/src/silc/core/silc-servers.c.
5254 Added ACTION local command. It is same as ME command but takes
5255 the channel as mandatory argument.
5257 Rewrote some of the Irssi's help files to suite for SILC
5260 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Added Makefile.defines[.in] that should for now on be included
5263 in all Makefile.am file in the source tree. That file includes
5264 all common compilation definitions for SILC source tree.
5266 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Minor changes to the ./prepare script to change the package
5269 name according the distribution name to the configure.in.
5271 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Created new distribution system. Added file `distributions'
5274 that defines all the distributions that can be created out of
5275 the SILC source tree. The ./prepare script now reads that
5276 file to determine how to prepare the distributions. The
5277 first argument to the ./prepare is the name of the distribution
5278 and second is the version of the distribution. If given
5279 without arguments it creates the default (toolkit) distribution
5280 with the default version (defined in ./prepare).
5282 All Makefile.am files that are subject to the distributions
5283 are now named as Makefile.am.pre. These are ./Makefile.am
5284 and lib/Makefile.am. Others may be changed later.
5286 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Added invite list, ban list, some key management and connection
5289 error message printing to module formats in the Irssi SILC client.
5291 * Added new silc_client_set_away_message to set the away message
5292 that is back to the person who sent private message. The
5293 affected file lib/silcclient/silcapi.h and the
5294 lib/silcclient/client_prvmsg.c.
5296 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Fixed the private message sending in the Irssi SILC client,
5299 added local command KEY to the Irssi SILC client.
5301 Added key management and key agreement message formats to the
5302 irssi/src/fe-common/silc/module-formats.[ch].
5304 Added USERS (alias WHO) printing, server/router operator
5305 indication and LIST command printing to the module formats.
5307 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Fixed channel joining notify handling, cumode notify handling
5310 from Irssi SILC client.
5312 * Added SILC specific module-formats to the Irssi SILC client so
5313 that SILC specific message hilighting, colors etc is possible.
5314 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5316 Added channel mode, channel user mode, actions, notices,
5317 whois and whowas printing to the the module-formats.c.
5319 * Fixed a bug in channel deletion in the server. The channel
5320 is not left to the cache even if the channel founder auth mode
5321 is set when there are no users anymore on the channel. Affected
5322 file silcd/server.c.
5324 * The silc_net_localhost now resolves the entire hostname including
5325 the domain name. Affected file lib/silcutil/silcnet.c.
5327 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Changed the ask_passphrase client operation to be ascynchronous.
5330 It has now a completion callback and a context that the
5331 application must call after it has got the passphrase from
5332 the user. Affected files lib/silcclient/silcapi.h,
5333 lib/silcclient/protocol.c, lib/silcclient/command.c and
5336 Added SilcAskPassphrase callback that the application calls
5337 to deliver the passphrase to the library.
5339 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5340 The public key verification and especially a certificate
5341 verification is asynchronous procedure.
5343 Added new SILC_SKE_STATUS_PENDING status to indicate the
5344 request is pending and a callback will be called to finalize
5347 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5348 indicate that remote end did not send its public key (or
5349 certificate), even though we require it. Added check for this
5350 condition in the SKE. This was a security bug, now fixed.
5352 Defined new SilcSKEVerifyCbCompletion callback that is called
5353 when the verification process is completed.
5355 The affected files lib/silcske/silcske_status.h and
5356 lib/silcske/silcske.[ch].
5358 * Changed the verify_public_key client operation to be async
5359 as well. Defined SilcVerifyPublicKey callback that is used to
5360 indicate the success of the public key verification process.
5362 Changed the server and client to use the new async client
5365 * Changed the Irssi SILC client's internal scheduler to be called
5366 twice as many times as it used to be. As a result the client
5367 should be a bit faster now. Affected file is
5368 irssi/src/silc/core/silc-core.c.
5370 * Added support to Irssi SILC client of asynchronous public key
5371 verification and passphrase inquiry. Affected file is
5372 irssi/src/silc/core/silc-core.c.
5374 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Do not say "You have left channel %s" in client library.
5377 Moved it to the application. Affected files are
5378 lib/silcclient/command.c and silc/client_ops.c.
5380 * Fixed silc_client_get_clients. Command context was not
5381 duplicated and was freed memory in the callback. Affected
5382 file lib/silcclient/idlist.c.
5384 * Do not say "you are now talking..." on JOIN command in the
5385 client library. The appliation must handle it.
5387 * Do not say ".. changed topic to" in command reply in the
5388 client libary. The application must handle it.
5390 * Fixed TOPIC command sending in the client library.
5392 * Fixed a memory leak in silc_client_command_free in the file
5393 lib/silcclient/command.c.
5395 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Imported a modified version of Irssi client to the source tree.
5398 The Irssi will be used to create a new client called
5399 Irssi SILC. Imported to irssi/.
5401 Added silc_core_init_finish function to the Irssi. Affected
5402 file irssi/configure.in.
5404 A lot changes in the Makefile.ams around the irssi tree.
5406 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Do not rehash if the new size is same as the old size of the
5409 hash table, in the silc_hash_table_rehash*. The affected file
5410 lib/silcutil/silchashtable.c.
5412 * Replaced hash_table_del_by_context calls from the server
5413 (when channel->user_list and client->channels) to the
5414 hash_table_del as it is sufficient and faster.
5416 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Added silc_hash_table_list, silc_hash_table_get and the
5419 SilcHashTableList structure to provide an alternative way to
5420 traverse the hash table. The affected files are
5421 lib/silcutil/silchashtable.[ch].
5423 * Changed the server's idlist routines to use the hash table
5424 routines to optimize the code.
5426 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Replaced the client entry's `channel' list and channel entry's
5429 `user_list' list to hash tables for optimized lookup. Changed
5430 the code to use the hash table interface around the code.
5431 Affected file lib/silcd/idlist.[ch].
5433 * Added `auto_rehash' boolean argument to the function
5434 silc_hash_table_alloc to indicate whether the hash table should
5435 auto-rehash when it thinks is appropriate time. It will
5436 increase the hash table size if the there is twice as much
5437 entries in the table than the size of the table, and will
5438 decrease the size if there are twice as less entries than
5439 the size of the table.
5441 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5445 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * silc_idcache_purge_by_context deletes the entry now by context
5448 as it is supposed to do. Affected file lib/silccore/idcache.c.
5450 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5451 client is not anymore valid (WHOWAS givens the info) and not
5452 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5454 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Removed the `data' and `data_len' arguments from the ID Cache
5457 interfaces and added `name' argument. ID Cache does not handle
5458 anymore the binary data only a names associated with given ID.
5460 * When hashing a Client ID with silc_hash_id the entire ID is
5461 not hashed anymore, instead only the hash of the Client ID is
5462 hashed. This way we can access the Client ID from the cache
5463 with Client ID but with the hash of the ID (which is a hash of
5464 the nickname) as well without any difference in performance.
5466 Added also silc_idcache_find_by_id_one_ext to do one on one
5467 searching when we have the actual ID. Added also function
5468 silc_hash_client_id_compare. The affected files are
5469 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5471 * When hashing the name associated with a ID it is always done
5472 in lowercase. This way we can access the cache without worrying
5473 about case-sensitivity, even though, for example nicknames are
5476 * Fixed a bug in server with channel message sending. It put
5477 wrong ID type as destination ID. The affected file
5478 silcd/packet_send.c.
5480 * silc_idcache_del_by_context now deletes from all hash tables
5481 by context. Affected file lib/silccore/idcache.c.
5483 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Changed the client library to use the new ID Cache interface.
5486 Changes around the source tree.
5488 * Added silc_hash_table_rehash_ext to rehash with specific
5489 hash function. Affected file lib/silcutil/silchashtable.[ch].
5491 * Added silc_hash_string_compare to compare two strings in the
5492 hash table. Affected file lib/silcutil/silcutil.[ch].
5494 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Added new function silc_idcache_del_by_context into the
5497 lib/silccore/idcache.[ch].
5499 * Changed the server's ID list routines to use the new ID Cache
5500 interface. Changes around the source tree.
5502 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Added silc_hash_table_del[_by_context]_ext functions in to the
5505 lib/silcutil/silchashtable.[ch].
5507 Removed silc_hash_table_find_all* routines and added new
5508 silc_hash_table_find_foreach to replace them.
5510 Added silc_hash_table_replace_ext function as extended
5511 replacing function. Separated the simple hash table interface
5512 from the extended hash table interface in the file
5513 lib/silcutil/silchashtable.h.
5515 * Fixed minor bugs and changed it to use some of the new
5516 hash table functions in lib/silccore/idcache.c
5518 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Added new function silc_hash_table_find_all to return all keys
5521 in the hash table by the specified key. As the hash table is
5522 collision resistant it also makes it possible to have several
5523 duplicate keys in the hash table. This function may be used to
5524 find all of the keys from the hash.
5526 Added user_context arguments to the SilcHashFunction,
5527 SilcHashCompare and SilcHashDestructor to deliver user specified
5530 Added new fuctions silc_hash_table_find[_all]_ext to do
5531 extended lookup with specified hash and compare functions and
5532 specified user contexts.
5534 Added new function silc_hash_table_add_ext to add the key
5535 with specified hash function and user context.
5537 Added new function silc_hash_table_foreach to traverse all
5538 entrys in the hash table. Added SilcHashForeach callback
5541 Added new function silc_hash_table_del_by_context to delete
5542 the entry only if the context associated with the key matches.
5544 Affected files are lib/silcutil/silchashtable.[ch].
5546 * Removed silc_hash_[server/client/channel]_id and added just
5547 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5548 silc_hash_id_compare to compare two ID's using as the hash table
5549 comparison function. Added also silc_hash_data to hash
5550 binary data and silc_hash_data_compare to compare it.
5552 * Removed silc_idlist_find_client_by_hash as it is not needed
5553 anymore. Affected file silcd/idlist.[ch].
5555 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5556 to use internally the SilcHashTable. The new ID Cache is a lot
5557 faster than the old one. Some of the ID Cache interface was also
5558 rewritten and obsolete and stupid functions were removed.
5560 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added entry_count field to the SilcHashTable to keep the number
5563 of the entries in the table. Implemented the function
5564 silc_hash_table_rehash. Added new function
5565 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5567 Fixed a minor bug in silc_hash_table_free.
5569 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5570 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5571 into the lib/silcutil/silcutil.[ch].
5573 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Implemented a collision resistant hash table into the
5576 lib/silcutil/silchashtable[ch]. See the header and the source
5577 for the SilcHashTable API.
5579 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Merged dotconf version 1.0.2 into lib/dotconf.
5583 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Do not compile anything in lib/silcsim/* if the SIM support
5586 is not enabled. The tree should now compile without problems
5589 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Compiled the SILC under cygwin. Compiled and tested briefly
5592 without problems. More tests needed. The SIMs didn't compile
5595 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5597 * Fixed possible crash in silc_get_username in the
5598 lib/silcutil/silcutil.c.
5600 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Fixed a va_arg in silc/client_ops.c.
5604 * Oops, RC5 routines were named AES and caused some problems
5605 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5607 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added new SilcIDIP structure into the lib/silccore/id.h and
5610 replaced the old `ip' fields from all SILC ID's to that type.
5611 This is a step towards IPv6 support.
5613 The silc_id_get_len takes now the ID as an extra argument.
5614 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5615 both IPv4 and IPv6 based ID's.
5617 The affected files are lib/silccore/id.[ch] and other files
5618 around the tree using these routines.
5620 * Removed the ID length arguments in server from various
5621 silc_server_send_notify_* routines -> they are not needed
5624 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Fixed memory leak in silc_encode_pem_file in the file
5627 lib/silcutil/silcutil.c.
5629 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Check minor version as well in the SKE. Affected files are
5632 silcd/protocol.c and lib/silcclient/protocol.c.
5634 * Added --identifier option to the server so that an identifier
5635 can be when creating the public key for the server. Affected
5636 file is silcd/silcd.c.
5638 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5639 lib/silccrypt/silcpkcs.c.
5641 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Register default ciphers and stuff when using -C option with
5644 the server. Affected file sildc/silcd.c.
5646 * Put back the servers public key filename format, it is better
5647 than the new one. For now, the client keys are saved with the
5648 new filename format. The affected file silc/client_ops.c.
5650 * Implemented the Cipher API for the rest of the ciphers that
5651 did not implement it or implemented it the wrong way.
5653 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Register default ciphers and stuff when using the -S option
5656 in the client. Affected file silc/silc.c. Same also when
5657 creating new key pair with -C option.
5659 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Fixed the silc_verify_public_key client operation function to
5662 save the public keys differently. The fingerprint is now
5663 used as filename and not the hostname. This way also the
5664 client keys are saved uniquely and not with hostnames. The
5665 affected file is silc/client_ops.c.
5667 * Trimmed the silc_hash_fingerprint function to remove extra
5668 whitespaces from the end of the fingerprint. The affected
5669 file is lib/silccrypt/silchash.c.
5673 * Added silc_cipher_register_default function to register all
5674 default ciphers. It can be used when configuration files
5675 does not exist and the application does not want any specific
5676 ciphers in any specific order.
5678 The SilcDList is now used as silc_cipher_list dynamically
5679 allocated cipher list. Removed the static list all together
5680 and now all ciphers must be allocated to the dynamic list.
5681 The silc_cipher_alloc routine was changed to check only the
5684 All silc_cipher_* routines that used to return int returns
5687 The affected files lib/silccrypt/silccrypt.[ch].
5689 * The same thing was done to silc_hash_* as for silc_cipher_*
5690 routines. Affected files lib/silccrypt/silchash.[ch].
5692 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5693 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5694 Added also silc_pkcs_[un]register[_default] functions.
5695 Removed the data_context from the PKCS API.
5697 * Added silc_hmac_register_default function to register default
5698 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5699 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5700 to unregister all hmacs at once.
5702 * Register the default ciphers, hash functions, PKCSs and HMACs
5703 if client's configuration file does not exist. The affected
5706 * The client did not load the hash functions from the SIM
5707 modules at all. Added support for this. Affected file is
5708 silc/clientconfig.c.
5710 * When decoding public key with silc_pkcs_public_key_decode, check
5711 the supported algorithm only if PKCS are registered. Affected
5712 file lib/silccrypt/silcpkcs.c. The same was done with the
5713 silc_pkcs_private_key_decode.
5715 * Fixed the SILC List routines to keep the list always in order.
5716 It used to change the list's order when traversing the list but
5717 not it preserves the order. Affected file lib/trq/silclist.h.
5719 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Added the client library to use the SilcSocketConnection's
5722 reference counter (by silc_socket_dup) to prevent the bug that
5723 the socket object may be freed underneath async operation.
5725 * The name resolv library checking fixes in the configure.in.pre.
5728 * Created new version of the protocol drafts for future
5729 development. The -03 drafts are the ones that will be changed
5730 in the trunk now and the -02 will remain as they are.
5732 * Send list of CUMODE notifys to the router when announcing
5733 the channel users to the router. Affected file silcd/server.c.
5734 If the router receiving channel founder CUMODE for a channel
5735 that already has channel founder it will send CUMODE notify
5736 to the sender to remove the channel founder rights from the
5737 announced client. Affected file silcd/packet_receive.c.
5739 * The CUMODE notify may now use Server ID as well as the entity
5740 who changes the mode. Updated protocool specs.
5742 * Updated INSTALL and README files.
5744 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * New web pages in the http://silc.pspt.fi. The pages was
5751 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Implemented the [DenyConnectin] config section in the server.
5754 Added silc_server_config_denied_conn to check whether incoming
5755 connection is denied. Affected file silcd/serverconfig.[ch].
5757 * Do not check the ports when checking the incoming configuration
5758 data if the port is 0, meaning any. Affected file is
5759 silcd/serverconfig.c.
5761 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Fixed buffer overflow in silc_string_compare in the file
5764 lib/silcutil/silcutil.c.
5766 * Fixed double free in silc_server_command_leave in the file
5769 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Fixed the version checking in the server. Affected file is
5774 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Fixed the configuration data fetching when accepting new
5777 connections in the server. Affected file silcd/server.c.
5779 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Added `sender_entry' argument to the function
5782 silc_server_packet_relay_to_channel so that we can check
5783 whether some destination actually belongs to the same route
5784 the sender belongs (ie, we must not resend the packet to the
5785 sender). Affected file silcd/packet_send.[ch].
5787 * Added `servername' field to the SilcClientEntry in the server
5788 to hold the name of the server where client is from. Affected
5789 file is silcd/idlist.h.
5791 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Moved the channel message encrypting in the router betwen
5794 router connections from silc_server_channel_message to the
5795 silc_server_packet_relay_to_channel since we want to check
5796 whether we have anybody channel before encrypting anything.
5797 Affected files silcd/packet_[receive/send].c.
5799 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Fixed the [AdminConnection] server config section to support
5802 multiple entries. Affected file silcd/serverconfig.c.
5804 * Added support into the server to check the validity of the
5805 incoming connection before executing any KE or authentication
5808 * The connection configuration is now saved to the KE and
5809 connection auth protocol contexts and not fetched anymore in
5810 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5812 * The local hosts listenning address and port is also resolved
5813 now when starting the server. We want to have the socket object
5814 to include the real address and port for the listener. Added
5815 new function silc_net_check_local_by_sock into the files
5816 lib/silcutil/silcnet.[ch].
5818 * Fixed a broadcast bug in server -> do not broadcast if we
5821 * Fixed a routing bug. Do not route broadcast packets ever.
5822 Broadcast packets must be processed always and not routed since
5823 they may be destined to some other host than yourself and thus
5824 would get routed without no good reason. Affected file is
5827 * Added function silc_server_config_is_primary_route to check
5828 whether primary router connection has been configured (a router
5829 configuration that we are initiating). If there is not, we
5830 will assume that there is only two routers in the SILC network
5831 and we will use the incoming router connection as our primary
5832 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5834 * Changed the order of the broadcasting. Broadcast _after_ the
5835 packet has been processed not before. Affected file is
5838 * Fixed a [ClientConnection] parsing bug. The port was never
5839 parsed correctly thus resulting to port 0. Affected file
5840 silcd/serverconfig.c.
5842 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5843 argument and did not set the broadcast packet flag. Affected
5844 file silcd/packet_send.c. Fixed same bug in the function
5845 silc_server_send_notify as well.
5847 * If we receive NEW_ID packet for our own ID in the server, ignore
5850 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Removed the nickname from the Private Message Payload.
5855 Updated the code and the protocol specs.
5857 * Updated protocol specs for submitting to the IETF.
5859 * Tweaked the Random Number Generator a bit. Affected file
5860 lib/silccrypt/silcrng.c. Exported a new function
5861 silc_rng_[global]_add_noise which can be used to add more
5864 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Do not parse packets with different timeout when protocol
5867 is active -> may cause problem with rekey. Affected file
5870 * When server receives signoff notify it must not create
5871 new channel key if the client is on any channels since the
5872 sender of the signoff notify will create it.
5874 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5876 * Added printing of error messages during SKE protocol from the
5877 failure packet sent by server during SKE. Affected file
5880 * Removed the client's failure_callback handling with timeout
5881 and handle it immediately when received.
5883 * The SKE library returned wrong type in SUCCESS and FAILURE
5884 packets. They must be 32 bit MSB not 16 bit MSB.
5886 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Ok, rewrote the logic of the re-key and now it seems to work.
5889 I tested it on high traffic with frequent re-keys without
5890 problems. Added hmac_receive (and renamed hmac to hmac_send)
5891 in SilcClientConnection in lib/silcclient/client.h and
5892 in SilcIDListData in silcd/idlist.h. Also, removed the
5893 SilcPacketParserContext's cipher and hmac fields as they are
5894 not needed anymore and actually caused some problems when
5895 the ciphers and hmac's changed underneath the packet parser.
5897 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * If re-key protocol is active then process the incoming packets
5900 synchronously since we must assure that icoming packets encrypted
5901 with the old key is processed before the new keys is set to
5902 use. This is true other packets than for REKEY packets.
5903 Affected file silcd/server.c. The same was done to client library
5904 as well, affected file lib/silcclient/client.c.
5906 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Fixed bug in client and server to accept the force send if
5909 the packet is send from silc_[server/client]_packet_process
5910 function. Otherwise the packets are never delivered, oops.
5912 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Disable force sending of packets when REKEY protocol is active.
5915 We must assure that no packet is sent directly when rekey is
5916 performed. All packets must be sent through packet queue.
5917 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5918 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5919 function is silc_[server/client]_packet_send_real to check
5922 * Replaced the SIM paths from example config files to
5923 /usr/local/modules. Also, make install creates now
5924 /usr/local/silc/logs directory to hold all the SILC server
5927 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Made the configure.in.pre work on Solaris. Patch by salo.
5931 * Made all ciphers compatible with non-x86 machines. Defined
5932 CBC mode macros into lib/silccrypt/ciphers_def.h.
5934 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Fixed the make install.
5938 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * When MAC computation fails the silc_packet_decrypt returned 0
5941 even though it was supposed to return -1. Fixed this. The
5942 affected file is lib/silccore/silcpacket.c.
5944 * Do not replace the config files in /etc/silc (in make install)
5945 if they already exist. Affected file ./Makefile.am.
5947 * Do not send re-key packets immediately but through packet queue.
5948 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5950 * Changed silc_net_check_host_by_sock to return FALSE if the
5951 IP/DNS could not be resolved. Though, it returns the IP address
5952 now even if it could not resolve it (but returns also FALSE).
5953 Affected file lib/silcutil/silcnet.[ch].
5955 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Added silc_pkcs_decode_identifier to decode the public key's
5958 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5959 Added also silc_pkcs_free_identifier. Added also new context
5960 SilcPublicKeyIdentifier.
5962 * Added -S option to the silc client. It is used to dump the
5963 contents of the specified public key file.
5965 * Changed the PKCS api to return the public key length when
5966 setting the public key.
5968 * Fixed a fatal bug in the public and private key file loading.
5969 Affected file lib/silccrypt/silcpkcs.c.
5971 * Execute the packet parsing for client with zero (0) timeout
5972 if the protocol is active. Affected file silcd/server.c.
5974 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Made the key generation options to the silcd program. Added
5977 -C option, equivalent to client's option.
5979 * Added new [ServerKeys] config section to the server. It
5980 configures the server's public and private key.
5982 * Defined generic Public Key Payload into the protocol
5983 specification to send specific type of public keys and
5986 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5987 public key or certificate.
5989 * Implemented the GETKEY command to the server and to the
5990 client library and on user interface.
5992 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Made preliminary `make install' work.
5996 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Added SilcServerRekey context into silcd/idlist.h.
6000 * Added the PFS support as defined in the specification to the
6001 SKE protocol. Affected files lib/silcske/*.c.
6003 * Added `ske_group' field to the SilcServerRekey context to hold
6004 the number of the SKE group that is used with PFS in re-key.
6005 Affected file silcd/idlist.h.
6007 * Added PFS re-key support to the server. Affected file is
6010 * Added silc_protocol_cancel to cancel execution of the next
6011 state of the protocol. Affected file is
6012 lib/silccore/silcprotocol.[ch].
6014 * Added the re-key support with and without PFS to the client
6015 library. Re-key is performed once in an hour, by default.
6017 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6018 Added silc_client_rekey_callback and silc_client_rekey_final.
6019 Affected files are lib/silcclient/protocol.[ch] and
6020 lib/silcclient/client.[ch].
6022 * Removed the `hmac_key' and `hmac_key_len' fields from the
6023 SilcClientConnection structure; not needed. Affected file is
6024 lib/silcclient/client.h.
6028 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Do not ask whether user wants to use the negotiated private key
6031 for private messages, just use it. Affected file is
6032 silc/local_command.c.
6034 * Added `send_enc_key' and `enc_key_len' fields to the
6035 SilcIDListData structure since they are needed in the re-key
6036 phase. Affected file is silcd/idlist.[ch].
6038 * Implemented the simple re-key protocol into the server.
6039 Affected files silcd/server.c and silcd/protocol.[ch]. The
6040 re-key will be performed once in an hour, by default.
6042 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6043 Added silc_server_rekey, silc_server_rekey_callback and
6044 silc_server_rekey_final.
6046 * Removed Tunneled flag from the protocol. Updated the code
6047 and the specifications.
6049 * Adde `pfs' field to the SilcIDListData to indicate whether
6050 the PFS is to be performed in the re-key. Affected file is
6053 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6056 int64 of at least the xintXX size. If void * is less that 4
6057 bytes uint32 * will be used. Defined bool as boolean.
6059 * Changed _ALL_ unsigned long and unsigned int to uint32,
6060 unsgined short to uint16 in the source tree.
6062 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6063 not handle clients that has entry->data.registered == FALSE.
6064 They are not in the network anymore. Affected file is
6067 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Implemented the sending of the SERVER_SIGNOFF notify in the
6070 server. Affected file is silcd/server.c.
6072 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6073 Added also silc_notify_payload_encode_args into the
6074 lib/silccore/silcnotify.[ch].
6076 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6077 Affected file silcd/packet_receive.c.
6079 * Implemented the SERVER_SIGNOFF notify handling in the client
6080 library. Affected file lib/silcclient/client_notify.c. Also,
6081 implemnted the printing of the SERVER_SIGNOFF info to the
6082 application. Affected file silc/client_ops.c.
6084 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6085 if the deleting was successful. Affected file silcd/idlist.[ch].
6087 * Added support for public key authentication in the connection
6088 authentication protocol in the client library. Affected file
6089 lib/silcclient/protocol.c.
6091 * Changed the server's silc_idlist_get_clients_by_* interface
6092 to support already allocated array so that new entries may be
6093 added to pre-allocated array. Affected file silcd/idlist.[ch].
6094 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6095 and command replies.
6097 * All command reply functions in the server now calls the
6098 pending command callback even if error occured. This way the
6099 error will be delivered to the client as well. Affected files
6100 silcd/command.c and silcd/command_reply.c.
6102 * Fixed INFO command to return local server's info if no server
6103 was provided. Affected file lib/silcclient/command.c.
6105 * Removed RESTART command for good. Updated the code and the
6108 * Rewrote parts of the task system. It is a bit simpler now.
6109 Removed unsued task priorities. The affected files are
6110 lib/silcutil/silctask.[ch].
6112 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Moved the USERS printing from the library to the application.
6115 Affected files lib/silcclient/command.c and silc/client_ops.c.
6117 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Added channel key re-key support. The re-key is perfomed
6122 only by the router and is done once in an hour. Added `rekey'
6123 field to the SilcChannelEntry in the server. Affected files
6124 silcd/server.c and silcd/idlist.h.
6126 * Added silc_task_unregister_by_context into the file
6127 lib/silcutil/silctask.[ch].
6129 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Added SILC_UMODE_GONE mode to indicate when the client is not
6132 present in the SILC network. Added also support to the local
6133 command AWAY that will set this mode. Added support of showing
6134 "xxx is gone" in WHOIS command. The USERS command shows the
6135 gone status as well.
6137 * Fixed setting server and router operator privileges in the
6138 server's UMODE command. Affected file silcd/command.c.
6140 * Merged the SKE KE1 and KE2 payloads into one payload. The
6141 new KE payload is equivalent to the old KE2 payload.
6143 Cleaned up the SKE Start Payload parsing. It now uses the
6144 simple buffer unformatting to do the parsing. A lot faster
6147 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6148 to the SKE that is used to indicate whether both of the SKE
6149 parties should perform authentication. By default only the
6150 responder performs authentication. By setting this flag also
6151 the initiator must do authentication. By default it is unset
6152 since in normal SKE case, client to server connection, only
6153 the responder should do authentication. When doing SKE between
6154 two clients both should perform authentication. Updated the
6155 code and the protocol specs.
6157 * A little fix to IDENTIFY command in the server. Search the
6158 client first by hash not nickname. Affected file is
6161 * Fixed the silc_client_close_connection to support closing
6162 the client to client connections wihtout deleting too much
6163 data. Affected file lib/silcclient/client.c.
6165 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6166 are received if protocol used to be active but is not anymore
6167 the application would crash due to NULL pointer dereference.
6168 Affected files silcd/server.c and lib/silcclient/client.c.
6170 * Added `hash' field to the SilcClientConnection to include
6171 the hash function negotiated in the SKE protocol.
6173 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6174 to set the channel founder authentication data. A client can
6175 claim the founder rights later by providing the authentication
6176 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6177 This way the channel founder can regain the channel founder
6178 privileges even it is left the channel. This works only on
6179 local server and the client must be connected to the same
6180 server to be able to regain the founder rights. Updated the
6181 protocol specs accordingly.
6183 Added support to the CMODE command in the client to set the
6184 founder auth data. Read the README to see how to set it.
6186 Added support to the CUMODE command to claim the founder
6187 rights. Read the README to see how to do it.
6189 Added support for the founder authentication to the Channel
6190 Entry in the server. Affected file silcd/idlist.h.
6192 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6193 server's CMODE command. Affected file silcd/command.c.
6195 * Added the following new functions into lib/silccore/silcauth.[ch]:
6196 silc_auth_get_method and silc_auth_get_data.
6198 * The server now saves the remote hosts public key to the
6199 SilcIDListData pointer. Affected file silcd/protocol.c.
6201 * The normal server now does not remove the channel entry from
6202 the cache if the founder authentication data is set. It used
6203 to remove it if the founder was the last one on the channel on
6204 the server and left the channel. The auth data is saved and
6205 if the channel is re-joined later the old entry is used with
6206 the old auth data. Affected files silcd/command_reply.c and
6209 * Removed the `pkcs' field from the SilcIDListData structure
6210 in the server; it is not used. Affected file silcd/idlist.h.
6212 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Fixed packet processing on slow links. Partial packets were
6215 never re-processed because the incoming data buffer was cleared
6216 by the application. Application must not directly clear the
6217 sock->inbuf, the packet processing routines handle it. Fixed
6218 this in client library and in server.
6220 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Fixed the WHOIS and IDENTIFY send reply function to really
6223 check whether to send list or just one entry. Affected file
6226 * Cleaned up the LEAVE command's channel key distribution. The
6227 affected file silcd/command.c.
6229 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6230 can enforce the channel mode as well. In that case the ID
6231 includes the ID of the server. The code now enforces the
6232 mode change if the router have different mode than the server.
6234 * The notify client operation with CMODE_CHANGE notify can now
6235 return NULL client_entry pointer if the CMODE was not changed
6236 by client. Application must check for this.
6238 * Added <Server ID> argument to INFO command to support server
6239 info fetching by Server ID.
6241 * Added silc_server_announce_get_channel_users to get assembled
6242 packets of channel users of the specified channel. Affected
6243 file silcd/server.[ch].
6245 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6246 was freed underneath the ID Cache.
6248 * Re-announce clients when the server received CHANNEL_CHANGE
6249 notify from the router. Affected file silcd/packet_send.c.
6251 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6254 crashed since it did not handle the fact that there is no cipher
6255 called "3" and didn't check the error condition. Now fixed.
6257 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6258 flag. It can be used to send message requests.
6260 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Implemented the RESTART command in the client.
6264 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6265 notice type messages. Added notice printing to the user
6268 * The channel keys are not re-generated if the channel's mode
6269 is PRIVKEY, ie private key on the channel exists. Affected
6270 files silcd/server.c and silcd/command.c.
6272 * Fixed a little bug in channel message delivery when channel
6273 private keys are set in the server. Affected file is
6274 silcd/packet_send.c.
6276 * Changed the setting on channel->on_channel = TRUE from the
6277 silc_client_save_channel_key to the JOIN command reply. The
6278 key payload is not received if the private channel key is set.
6279 Affected file lib/silcclient/command_reply.c and the
6280 lib/silcclient/client_channel.c.
6282 * When the CMODE_CHANGE notify is sent and the channel private
6283 key mode is removed the channel key must be re-generated in
6284 other cells as well. Added this support for the router in the
6285 silcd/packet_receive.c.
6287 * Added new local command NOTICE to send notice message on
6288 channel. Affected file silc/local_command.[ch].
6290 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6292 * Added new local command ME to the client. It is used to send
6293 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6294 some action. Affected file silc/local_command.[ch].
6296 * Changed channel_message and private_message client operations
6297 to deliver the message flags to the application. Added also
6298 the `flags' arguments to the silc_client_send_channel_message
6299 and silc_client_send_private_message functions. Affected file
6302 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Redefined the Private Message Payload to support private message
6305 keys and to support the new private message flags. Updated
6306 the protocol specs. Flags makes it possible to have for example
6307 CTCP style messages.
6309 * Added new type SilcPrivateMessagePayload and defined an API
6310 for it in the lib/silcclient/silcprivate.[ch].
6312 * Tested private message private keys successfully. Tested the
6313 private message key set, unset and list commands with the new
6316 * Redefined the Channel Message Payload to include the channel
6317 message flags (equal with private message flags) to support
6318 for example CTCP style messages.
6320 * Defined some of the message (for channel and private message)
6321 flags. Updated the protocol specs and added the flags to the
6322 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6324 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Added SilcKeyAgreementStatus type to the key agreement routines
6327 to indicate the current status and error if one occured.
6328 The status types are defined in the lib/silcclient/silcapi.h.
6330 * Added new local command KEY that is used to set and unset private
6331 keys for channels, set and unset private keys for private messages
6332 with remote clients and to send key agreement requests and
6333 negotiate the key agreement protocol with remote client. The
6334 key agreement is supported only to negotiate private message keys,
6335 it currently cannot be used to negotiate private keys for channels,
6336 as it is not convenient for that purpose.
6338 * Fixed a minor pending callback setting bug in the function
6339 silc_client_get_client_by_id_resolve, now the function works.
6340 Affected file lib/silcclient/idlist.c.
6342 * Added function silc_net_get_local_port to get local bound
6343 port by socket. Added to lib/silcutil/silcnet.[ch].
6345 * Added `sockets' and `sockets_count' fields to the SilcClient
6346 object. They hold the sockets of the listenning sockets in
6347 the client. Listenning sockets may be for example the key
6348 agreement server. Affected file lib/silcclient/client.[ch].
6349 Added functions the silc_client_add_socket and the
6350 silc_client_del_socket. They are exported to the application
6353 * Added ~./silc/clientkeys to support other client's public keys.
6355 * Renamed verify_server_key client operation to verify_public_key
6356 and added one argument to indicate the type of the connection
6357 (server, client etc.).
6359 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6361 * Added silc_server_connection_auth_request to handle the
6362 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6363 silcd/packet_receive.[ch].
6365 * Added silc_server_send_connection_auth_request into the
6366 silcd/packet_send.c to send the connection auth request packet.
6368 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6371 * Fixed the public key authentication in responder side in the
6372 server. The `auth_data' pointer includes the SilcPublicKey
6373 not the path to the public key. Affected file silcd/protocol.c.
6375 * Implemented the public key authentication in the initiator side
6376 in the server. Affected file silcd/protocol.c.
6378 * Removed the [RedirectClient] config section from the server
6379 configuration. Is not needed and I don't want to implement it.
6381 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Cleaned up the CMODE command in the server. It now works
6384 correctly and supports all the modes defined in the protocol.
6385 Affected file is silcd/command.c.
6387 * Added `hmac_name' field to the SilcChannelEntry in the server
6388 to hold the default HMAC of the channel. It can be set when
6389 creating the channel (with JOIN command). Affected files
6392 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6393 type to indicate the change of the current cipher and hmac
6394 on the channel. Client can safely ignore the <cipher> argument
6395 (if it chooses to do so) since the CHANNEL_KEY packet will
6396 force the channel key change anyway. The <hmac> argument is
6397 important since the client is responsible of setting the new
6398 HMAC and the hmac key into use.
6400 * Fixed the CMODE command in the client library as well.
6402 * Tested CMODE command in router environment successfully.
6404 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Show the version of the remote client (or server) when connecting
6407 to the server. It is logged to the log file. Affected file
6408 is silcd/protocol.c.
6410 * Fixed the KILLED notify handling in the client library. The
6411 client must be removed from all channels when receiving the
6414 Also, do not remove the client entry when giving the KILL
6415 command but when the KILLED notify is received.
6417 * Removed silc_idlist_find_client_by_nickname from the server.
6418 Not needed anymore. Affected files silcd/idlist.[ch].
6420 * Implemented the CHANNEL_CHANGE notify type handling to the
6421 server. Affected file silcd/server.c.
6425 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6427 * Added silc_server_send_notify_invite to send the INVITE
6428 notify between routers.
6430 * Implemented the INVITE command correctly to the server.
6432 * Implemented the INVITE notify type handling in the server.
6434 * Implemented the INVITE command to the client library and on the
6437 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Added function silc_server_get_client_resolve to find the
6440 client entry by ID from all ID lists and then resolve it
6441 (using WHOIS) if it cannot be found. Affected file is
6444 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Implemented the BAN command to the client library.
6448 * The JOIN command in the server now checks the invite list
6451 * Changed the silc_command_reply_payload_encode_va and the
6452 silc_command_payload_encode_va to support that if argument is
6453 NULL it ignores and checks the next argument. Affected file
6454 lib/silccore/silccommand.c.
6456 * Added silc_server_send_notify_ban to send the BAN notify
6457 type between routers.
6459 * Chaned the silc_notify_payload_encode to support that if
6460 argument is NULL it ignores and checks the next argument.
6461 Affected file lib/silccore/silcnotify.c.
6463 * Tested ban lists in router environment successfully.
6465 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Implemented BAN command to the server, in silcd/command.[ch].
6469 * Removed the BAN and INVITE_LIST modes from the CMODE command
6472 * Added function silc_string_match to regex match two strings.
6473 Affected files lib/silcutil/silcutil.[ch].
6475 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Redefined parts of the SilcChannelEntry in the server to support
6478 the new ban and invite lists.
6480 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Redefined the INVITE command. The same command can be used to
6483 invite individuals to the channel but also to manage the invite
6484 list of the channel (to add to and remove from the invite list).
6485 Updated the protocol specs.
6487 * Added new command SILC_COMMAND_BAN that can be used to manage
6488 the ban list of the channel. Updated the protocol specs.
6490 * Removed the channel modes: the SILC_CMODE_BAN and the
6491 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6492 in the CMODE command. The equivalent features are now available
6493 using INVITE and BAN commands. Updated the protocol specs.
6495 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6496 in the network about change in the current ban list. The notify
6497 type is not used by the client.
6499 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6500 support the invite lists.
6502 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Added new function silc_string_regexify that converts string
6505 including wildcard characters into regex string that can
6506 be used by the GNU regex library. Added into the file
6507 lib/silcutil/silcutil.[ch].
6509 Added silc_string_regex_combine to combine to regex strings
6510 into one so that they can be used as one regex string by
6511 the GNU regex library. Added into the file
6512 lib/silcutil/silcutil.[ch].
6514 Added silc_string_regex_match to match two strings. It returns
6515 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6517 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Imported GNU regex to the soruce tree into lib/contrib.
6520 Fixed some compiler warning from the regex.c.
6522 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * Fixed MOTD command in the server to work in router environment.
6526 * Fixed the MOTD command in the client library to support
6527 the server argument in the command.
6529 * Added `nickname_len' argument to the silc_idlist_add_client
6530 in the server, as the `nickname' argument may be binary data
6533 * Added silc_idlist_get_channels to return all channels from
6536 * Implemented LIST command to the server. Affected file is
6539 * Implemented the LIST command to the client library and on the
6542 * Added [<user count>] argument to the LIST command reply.
6543 With private channels the user count is not shown.
6545 * Updated TODO and README.
6547 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * The client entry's data.registered must be TRUE even with
6550 global client entry on global client list. The data.registered
6551 is used to check whether the client is anymore in the network,
6552 for example with WHOWAS command so it must be valid.
6554 * Fixed the WHOWAS command in the server. It now actually works
6555 in router environment. Added function into silcd/command_reply.c
6556 silc_server_command_reply_whowas_save.
6558 * Added silc_idlist_purge function to the silcd/idlist.c
6559 to periodically purge the ID Cache.
6561 * Fixed INFO command in the server. It works now in router
6562 environment. Added <server name> argument to the INFO command
6563 reply. Updated the protocol specs.
6565 * Fixed minor bug in silc_idcache_purge to not purge if the
6566 expire value is zero.
6568 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6569 they were buggy because of the WHOWAS information.
6571 * Fixed local command MSG to handle the async resolving of
6572 the remote client properly. It used to fail the first MSG.
6573 Affected file silc/local_command.c.
6575 * Added `data_len' field to SilcIDCache context.
6577 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Update TODO. Todo in commands in the server.
6581 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6584 used by routers as broadcast packet to inform other routers
6585 about the changed user mode.
6587 Implemented the notify handling in the server. Affected file is
6588 silcd/packet_receive.c. Added the function
6589 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6591 * Added new generic Channel Payload and deprecated the New Channel
6592 Payload. The New Channel Payload is now the generic Channel
6595 * Added new argument `mode' to the silc_server_send_new_channel
6596 as it is required in the Channel Payload now.
6598 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6599 and created a new and real SilChannelPayload to represent the
6600 new generic Channel Payload. Implemented the encode/decode
6601 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6603 * Added silc_server_get_client_channel_list to return the list
6604 of channels the client has joined for WHOIS command reply.
6605 Affected file silcd/server.[ch].
6607 * Implemented the channel list sending in the WHOIS command reply
6608 in server and in the client.
6610 Implemented the channel list displaying on the user interface
6611 as well. Affected file silc/client_ops.c.
6613 * Added silc_channel_payload_parse_list to parse list of Channel
6614 Payloads. It returns SilcDList list of SilcChannelPayloads.
6615 Client for example can use this function to parse the list of
6616 channels it receives in the WHOIS command reply. The caller
6617 must free the list by calling silc_channel_payload_list_free.
6618 Affected files lib/silccore/silcchannel.[ch].
6620 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Added one new argument <user mode> to the WHOIS command reply
6623 to return the mode of the user in SILC. Updated the protocol
6626 Implemented it to the server and client.
6628 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Fixed the mode printing on the user interface on joining.
6631 Affected file silc/client_ops.c.
6633 * Implemented the UMODE command and user modes in general to the
6634 client library and to the user interface.
6636 * Implemented the UMODE command to the server.
6638 * The server now sends UNKNOWN_COMMAND error status if client sends
6639 unknown command. Affected file silcd/command.c.
6641 * All server commands now handle the command identifier the right
6642 way when sending the command reply to the client. The client can
6643 use to identify the command replies with the identifier.
6645 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added silc_server_get_client_route to resolve the route to
6648 the client indicated by the client ID. Affected file is
6651 * Added silc_server_relay_packet as general function to relay
6652 packet to arbitrary destination. This deprecates functions
6653 like _send_private_message_key, _relay_notify etc. Affected
6654 file is silcd/packet_send.[ch].
6656 Removed silc_server_send_key_agreement,
6657 silc_server_send_private_message_key and
6658 silc_server_packet_relay_notify functions from the file
6659 silcd/packet_send.[ch].
6663 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6664 server. Affected file silcd/packet_receive.[ch].
6666 * Implemented the KILL command to the client. Implemented the
6667 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6668 Affected files lib/silcclient/command[_reply].c and
6669 lib/silcclient/client_notify.c. Implemented the KILL notify
6670 printing in the user inteface.
6672 * Fixed a lot silc_parse_nick memory leaks from the client
6673 library in the file lib/silcclient/command.c.
6675 * Changed the silc_server_send_notify_on_channels's `sender'
6676 argument from SilcSocketConnection to SilcClientEntry to
6677 check the sender as entry and not as connection object and not
6678 to send to the client provided as argument. The affected file
6679 is silcd/packet_send.[ch].
6681 * The notify packets that are destined directly to the client used
6682 to not to be processed by the server. Now changed that and the
6683 server processes all notify packets. After relaying the packet
6684 to the client the notify packet is processed in the server.
6686 * The silc_server_free_client_data now checks whether there is
6687 pending outgoing traffic for the client and purges the data to
6688 the network before removing the client entry.
6690 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6693 an client is killed from the SILC Network. Updated the protocol
6696 Added new function silc_server_send_notify_killed to the
6697 silcd/packet_send.[ch].
6699 * Added function silc_server_packet_relay_notify to relay notify
6700 packets that are destined directly to a client. In this case
6701 the server does not process the notify packets but merely relays
6702 it to the client. Affected file silcd/packet_send.[ch].
6704 Added also silc_server_packet_process_relay_notify to check
6705 whereto relay the notify. Affected file is
6706 silcd/packet_receive.[ch].
6708 * Implemented the KILL command to the server.
6712 * Added the backup schema desgined last fall to the protocol
6713 specs for everyone to see. The specification is in the
6714 *-spec-xx.txt draft and the packet type definitions for the
6715 backup routers is in *-pp-xx.txt draft. Thusly, added also
6716 new packet type SILC_PACKET_CELL_ROUTERS.
6718 * A big security problem in the implementation discovered. The
6719 signoff of an client did not cause new channel key generation
6720 which it of course should've done. The channel keys must be
6721 always re-generated when client leaves (or signoffs) the channel.
6722 The silc_server_remove_from_channels funtion now handles
6723 the channel key re-generation.
6725 * Added `sender' argument to the silc_server_send_notify_on_channels
6726 to not to send the client provided as argument. Affected file
6727 silcd/packet_send.[ch].
6729 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Implemented OPER and SILCOPER commands into the server and
6734 * Added silc_auth_verify and silc_auth_verify_data to verify
6735 the authentication directly from the authentication payload.
6736 It supports verifying both passphrase and public key based
6737 authentication. Affected file lib/silccore/silcauth.[ch].
6739 * Added `hash' field to the SilcIDListData structure. It is the
6740 hash negotiated in the SKE protocol. Affected file is
6743 * Slight redesigning of the SilcAuthPayload handling routines.
6744 Do not send SilcPKCS but SilcPublicKey as argument.
6746 * Implemented the public key authentication support to the
6747 serverconfig. The public key is loaded from the provided path
6748 and saved as authentication data to void * pointer. Thus,
6749 changed the unsigned char *auth_data to void *auth_data;
6751 * Fixed SHUTDOWN command to send the reply before the server
6752 is shutdown. :) Affected file silcd/command.c.
6754 * Fixed fatal bug in CONNECT command. The hostname was invalid
6755 memory and server crashed. Affected file silcd/command.c.
6757 * Fixed fatal bug in CLOSE command. The server_entry became
6758 invalid but was referenced later in the command. Affected file
6761 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Fixed fatal bug in failure packet handling. Server ignored
6764 the failure and thus crashed when it came.
6768 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6771 that the command may be executed only once in (about) 2 seconds.
6772 The old SILC_CF_LAG flag is same but allows command bursts up
6773 to five before limiting.
6775 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6776 server code. Various commands now includes the CF_LAG_STRICT
6777 flag to disallow any kind of miss-use of the command.
6779 * Fixed the silc_buffer_unformat to not to allocate any data
6780 if the length of the data is zero. It used to allocate the
6781 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6783 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Changed the format of AdminConnection configuration section
6786 in the server. Added username of the admin to the format.
6787 Affected files silcd/serverconfig.[ch].
6789 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6790 to return admin configuration data by host, username and/or
6793 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Implemented WHOWAS command to the server. Added the functions:
6797 silc_server_command_whowas_parse,
6798 silc_server_command_whowas_send_reply,
6799 silc_server_command_whowas_from_client and
6800 silc_server_command_whowas_from_server
6802 * Added <Client ID> argument to the WHOWAS command reply. Updated
6803 the protocol specs accordingly.
6805 * Implemented WHOWAS command and command_reply to the client
6808 Implemented the WHOWAS printing on the user interface.
6810 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Added new argument to the WHOWAS command reply, the real name.
6813 It is an optional argument. Updated the protocol specs.
6815 * Added SilcIDCacheDestructor callback that is registered when
6816 the SilcIDCache is allocated. The callback is called when
6817 an cache entry in the ID Cache expires, or is purged from the
6818 cache. Added into lib/silccore/idcache.[ch].
6820 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6821 to destruct the client entries when the cache entry expires.
6822 Other ID Cache's in server and in the client library ignores
6825 * If the ID Cache entry's `expire' field is zero then the entry
6826 never expires. Added boolean `expire' argument to the
6827 silc_idcache_add function in the lib/silccore/idcache.[ch].
6828 If it is TRUE the default expiry value is used.
6830 * Added silc_server_free_client_data_timeout that is registered
6831 when client disconnects. By default for 5 minutes we preserve
6832 the client entry for history - for WHOWAS command.
6834 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Added support to the server to enforce that commands are not
6837 executed more than once in 2 seconds. If server receives
6838 commands from client more frequently, timeout is registered
6839 to process the commands. Affected file silcd/command.c.
6840 Added new function silc_server_command_process_timeout.
6842 * Changed NICK_NOTIFY handling in client library to check that
6843 if the client's nickname was changed, so there is no need to
6844 resolve anything from the server.
6846 * Removed error printing from the WHOIS and IDENTIFY commands.
6847 If error occurs then it is ignored silently in the client library.
6848 The application, however, may map the received error to
6849 human readable error string. The application currently maps
6850 the NO_SUCH_NICKNAME error to string.
6852 * Made the command status message public to the application. Moved
6853 them from lib/silcclient/command_reply.c to
6854 lib/silcclient/command_reply.h. The application can map the
6855 received command status to the string with the
6856 silc_client_command_status_message function.
6858 * Added check to the server to check that client's ID is same
6859 as the Source ID in the packet the client sent. They must
6862 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * Added dist-bzip hook to the Makefile.am to make bzip2
6865 compressed distributions.
6867 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Server now enforces the maximum length for the nickname and
6870 the channel as protocol specification dictates. 128 bytes for
6871 nickname and 256 bytes for channel name.
6873 * Moved the WHOIS printing to the application. The client libary
6874 does not print out the WHOIS information anymore, the application
6875 must do it. Renamed silc_client_command_reply_whois_print to
6876 the silc_client_command_reply_whois_save.
6878 The client's idle time is also sent to the application now, and
6879 the idle is shown on screen.
6881 * Added silc_client_command_reply_identify_save to save the
6882 received IDENTIFY entries.
6884 * Do not check for channel private keys in message sending and
6885 reception if the channel does not have the PRIVKEY mode set.
6886 Affected file lib/silclient/client_channel.c.
6888 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6891 just surfaced after chaning the JOIN procedure.
6893 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Added silc_client_get_clients_by_list to get client entries
6896 from Client ID list, that is returned for example by JOIN
6897 and USERS command replies. The application should use this
6898 function for example when JOIN command reply is received to
6899 resolve the clients already on the channel (library does not
6900 do that anymore as USERS command reply is not used in the JOIN
6901 procedure anymore). Affected files lib/silcclient/silcapi.h and
6902 lib/silcclient/idlist.c.
6904 * JOIN command reply and USERS command reply returns now SilcBuffer
6905 pointers instead of unsigned char pointers when returning
6906 the client list and mode list.
6908 * Added <Client ID> argument to the JOIN command reply, mainly
6909 for the server to identify for which client the command was
6910 originally sent. Updated protocol specs accordingly.
6912 * Added SilcDlist private_key pointer to the SilcChannelEntry
6913 in the client to support the channel private keys. Affected
6914 file is lib/silcclient/idlist.h.
6916 * Added SilcChannelPrivateKey argument to the function
6917 silc_client_send_channel_message so that application can choose
6918 to use specific private ke if it wants to. If it is not provided,
6919 the normal channel key is used, unless private keys are set.
6920 In this case the first (key that was added first) is used
6921 as the encryption key.
6923 * Implemented the support for channel private key handling.
6924 Implemented the following functions:
6926 silc_client_add_channel_private_key,
6927 silc_client_del_channel_private_keys,
6928 silc_client_del_channel_private_key,
6929 silc_client_list_channel_private_keys and
6930 silc_client_free_channel_private_keys
6932 Affected file lib/silcclient/client_channel.c.
6934 * Added the support for the private keys in the channel message
6935 sending and encryption and in the message reception and
6936 decryption. Affected funtions are
6937 silc_client_send_channel_message and silc_client_channel_message.
6939 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Added SKE's key verify callback to the client library's
6942 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6944 * Removed the statement that server (or router) must send USERS
6945 command reply when joining to the channel so that the client
6946 knows who are on the channel. Instead, the client list and
6947 client's mode list is now sent in the JOIN command reply to the
6948 client who joined channel. This is better solution.
6950 * Added function silc_server_get_users_on_channel and function
6951 silc_server_save_users_on_channel to the silcd/server.[ch].
6953 * Removed function silc_server_command_send_users from the
6956 * Do not show topic on the client library anymore. The topic is
6957 sent in the command reply notify to the application and the
6958 application must show the topic now.
6960 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Added client searching by nickname hash into the IDENTIFY and
6963 WHOIS commands in the server as they were clearly missing from
6964 them. Affected file is silcd/command.c.
6966 * Fixed a bug in private message receiving in the client library.
6967 The remote ID was freed and it wasn't supposed, now it is
6970 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Minor fix to the channel payload; allocate the data area, as it
6973 needs to be of specific length.
6975 * If the key agreement port is zero then the operating
6976 system will define the bound port. Affected files are
6977 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6979 * Added new function silc_channel_payload_decrypt into the file
6980 lib/silccore/silcchannel.[ch].
6982 * Moved the channel message etc, check from silc_packet_decrypt
6983 to applications. The library calls now a generic
6984 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6985 when the packet is either normal or special. This was done to
6986 allow more wide range of checking that was not allowed when
6987 the code was in library. Now applications can do virtually any
6988 checks to the packet and return to the library the decision how
6989 the packet should be processed. Affected files are
6990 lib/silccore/silcpacket.[ch].
6992 Added silc_server_packet_decrypt_check to the server and
6993 silc_client_packet_decrypt_check to the client library.
6995 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6996 to send with specified source and destination information.
6998 * Channel message delivery between routers was broken after the
6999 channel key distribution was fixed earlier. The channel key
7000 was used be to distributed to other routers as well which is not
7001 allowed by the protocol. Now this is fixed and channel keys
7002 really are cell specific and the channel message delivery between
7003 routers comply with the protocol specification.
7005 * Fixed various commands in server to check also the global list
7006 for the channel entry and not just the local list. The affected
7007 file silcd/command.c.
7009 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Added assert()s to buffer formatting and unformatting routines
7012 to assert (if --enable-debug) when error occurs. Affected
7013 file: lib/silcutil/silcbuffmt.c.
7015 * Changed to auto-reconnect to check whether the remote host is
7016 router and register the re-connect timeout if it is. It used
7017 to check that whether we are normal server, but router must do
7018 auto-reconnect with another router as well. Affected file
7021 * Removed the [<key len>] option from CMODE command as the cipher
7022 name decides the key length, nowadays. See the defined ciphers
7023 from the protocol specification.
7025 * Added [<hmac>] option to the CMODE command to define the HMAC
7026 for the channel. Added SILC_CMODE_HMAC channel mode.
7028 * Added [<hmac>] option for the JOIN command so that user can
7029 select which HMAC is used to compute the MACs of the channel
7032 * Added Hmac field to the Channel Message Payload. The integrity
7033 of plaintext channel messages are now protected by computing
7034 MAC of the message and attaching the MAC to the payload. The
7035 MAC is encrypted. Now, it is clear that this causes some
7036 overhead to the size of the packet but rationale for this is that
7037 now the receiver can verify whether the channel message decrypted
7038 correctly and also when private keys are set for the channel the
7039 receiver can decrypt the packet with several keys and check from
7040 the MAC which key decrypted the message correctly.
7042 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7043 lib/silccrypt/silccipher.[ch].
7045 * Added silc_hash_len to return the digest length into the
7046 lib/silcrypt/silchash.[ch].
7048 * Rewrote parts of Silc Channel Payload interface in the
7049 lib/silccore/silcchannel.[ch]. The encode function now also
7050 encrypts the packet and parse function decrypts it.
7052 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7054 * Fixed a minor formatting bug in the SKE's key material processing.
7055 It actually might have processed the keys wrong way resulting
7058 * Redefined the mandatory HMAC algorithms and added new algorithms.
7059 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7060 and hmac-md5 truncated to 96 bits. The mandatory is now
7061 hmac-sha1-96. Rest are optional (including the one that used
7062 to be mandatory). Rationale for this is that the truncated HMAC
7063 length is sufficient from security point of view and can actually
7064 make the attack against the HMAC harder. Also, the truncated
7065 HMAC causes less overhead to the packets. See the RFC2104 for
7068 * Added new [hmac] configuration section. The SKE used to use
7069 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7070 is of course wrong. The official names that must be proposed in
7071 the SKE are the ones defined in the protocol specification
7072 (hmac-sha1-96 for example). The user can configure any hmac
7073 using any hash function configured in the [hash] section. At
7074 least, the mandatory must be configured.
7076 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7078 * Added HMAC list to the SKE proposal list. It has now both
7079 hash algorithm list and HMAC list. This makes the protocol
7080 incompatible with previous versions. The SKE now seems to work
7081 the way it is supposed to work, for the first time actually.
7083 * Defined plain Hash algorithms to the protocol specification.
7086 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Implemented support for key agreement packets into the server.
7089 Added functions silc_server_key_agreement and
7090 silc_server_send_key_agreement. Other than these functions,
7091 server has nothing to do with this packet.
7093 * Added support for private message key packets into the server.
7094 Added functions silc_server_private_message_key and
7095 silc_server_send_private_message_key.
7099 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7100 called in the protocol's final callback instead in the END
7101 protocol state. This makes a little more sense and in the same
7102 time in client we can use the same protocol routines for normal
7103 key exchange and to key agreement packet handling as well.
7105 * Added to both client's and server's KE protocol context the
7106 SilcSKEKeyMaterial pointer to save the key material. We will
7107 bring the key material to the protocol's final callback by doing
7108 this. The final callback must free the key material.
7110 * Added SKE's packet_send callback into client's KE protocol
7111 context so that the caller can choose what packet sending function
7112 is used. This way we can use different packet sending when
7113 doing normal SKE when doing key agreement packet handling (in
7114 the key agreement packet handling we do not want to encrypt
7117 * Implemented the responder side of the key agreement routines
7118 in the client. The client can now bind to specified port and
7119 accept incoming key negotiation. The key material is passed
7120 to the application after the protocol is over.
7122 * Implemented the processing of incoming Key Agreement packet
7123 in the client. Added function silc_client_key_agreement to
7126 * Implemented the intiator side of the key agreement routines
7127 in the client. The client can now initiate key agreement with
7128 another remote client. The key material is passed to the
7129 application after the protocol is over.
7131 * Created client_keyagr.c to include all the key agreement
7134 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7135 SILC_TASK_CALLBACK except that it is not static.
7137 * Created client_notify.c and moved the Notify packet handling
7138 from the client.[ch] into that file.
7140 * Created client_prvmsg.c and moved all private message and
7141 private message key routines from the client.[ch] into that file.
7143 * Create client_channel.c and moved all channel message and
7144 channel private key routines from the client.[ch] into that file.
7146 * Changed silc_client_get_client_by_id_resolve to resolve with
7147 WHOIS command instead of IDENTIFY command, in the file
7148 lib/silclient/idlist.c.
7150 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Implemented the SKE's responder side to the Client library.
7154 * When FAILURE is received to the protocol do not trust it
7155 blindly. Register a timeout to wait whether the remote closes
7156 the connection as it should do it, only after that process the
7157 actual failure. This was changed to both client and server.
7159 * Added client_internal.h to include some of the structures
7160 there instead of client.h in lib/silcclient/.
7162 * Added function silc_task_unregister_by_callback to unregister
7163 timeouts by the callback function.
7165 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * Some "Incomplete WHOIS info" errors has been appearing on the
7168 log files. Took away the entry->userinfo check from WHOIS
7169 reply sending. The entry->userinfo is now " " if client did not
7170 provide one. I thought this was fixed earlier but something
7171 is wrong still. Let's see if the error still appears.
7173 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7175 * Fixed a minor bug in the login when the channel key is
7176 re-generated in the server. It used to generate the key in
7177 wrong order and thus caused problems in the channel traffic.
7179 * Fixed a minor bug in channel key distsribution after
7180 KICK command. The key was not sent to the router even though
7183 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Added silc_ske_process_key_material_data as generic routine
7186 to process any key material as the SILC protocol dictates. The
7187 function is used by the actual SKE library but can be used by
7188 applications as well. This relates to the private message keys
7189 and the channel private keys since they must be processed the
7190 same way the normal SILC session keys. The protocol dictates
7191 this. Affected files: lib/silcske/silcske.[ch].
7193 Added also silc_ske_free_key_material to free the
7194 SilcSKEKeyMaterial structure.
7196 * Defined silc_cipher_set_key function to set the key for
7197 cipher without using the object's method function. The affected
7198 files: lib/silccrypt/silccipher.[ch].
7200 * Implemented silc silc_client_add_private_message_key,
7201 silc_client_add_private_message_key_ske,
7202 silc_client_del_private_message_key,
7203 silc_client_list_private_message_keys and
7204 silc_client_free_private_message_keys functions in the
7207 Added functions silc_client_send_private_message_key to send
7208 the Private Message Key payload and silc_client_private_message_key
7209 to handle incoming Private Message Key payload.
7211 * Added Cipher field to the Private Message Key payload to set
7212 the cipher to be used. If ignored, the default cipher defined
7213 in the SILC protocol (aes-256-cbc) is used.
7215 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * Removed lib/silcclient/ops.h file.
7219 Redefined parts of the SILC Client Library API. Created new
7220 file silcapi.h that deprecates the ops.h file and defines the
7221 published Client Library API. Defined also private message key
7222 API and channel private key API into the file.
7224 This is the file that the application must include from the
7225 SILC Client Library. Other files need not be included by
7226 the application anymore.
7228 * Added new key_agreement client operation callback and also
7229 defined the Key Agreement library API for the application.
7231 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7234 is used by clients to request key negotiation between another
7235 client in the SILC network. If the negotiation is started it
7236 is performed using the SKE protocol. The result of the
7237 negotiation, the secret key material, can be used for example
7238 as private message key.
7240 Implemented the Key Agreement payload into the files
7241 lib/silccore/silauth.[ch].
7243 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Redefined ciphers for the SILC protocol. Added some new ciphers
7246 and defined the key lengths for the algorithms. Changed the
7247 code accordingly. The default key length is now 256 bits.
7249 * Fixed SKE key distribution function silc_ske_process_key_material
7250 when the key length is more than 128 bits. The default key
7251 length in SILC is now 256 bits.
7253 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7254 to indicate unsupported algorithm.
7256 * Renamed rijndael.c to aes.c and all functions as well.
7258 * Fixed a long standing channel key setting bug in client library.
7259 Weird that it has never surfaced before.
7261 * Fixed bug in channel deletion. If the entire channel is removed
7262 then it must also delete the references of the channel entry
7263 from the client's channel list as the client's channel entry and
7264 the channel's client entry share same memory.
7266 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Implemented CONNECT and SHUTDOWN commands in the client.
7270 * Implemented CLOSE command to the client.
7272 * Added the function silc_idlist_find_server_by_name into the
7273 files silcd/idlist.[ch].
7275 Added the function silc_idlist_find_server_by_conn into the
7276 files silcd/idlist.[ch].
7278 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7280 * DIE command was renamed to SHUTDOWN. Updated the both code
7283 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7284 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7286 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7289 * Added function silc_server_create_connection function to create
7290 connection to remote router. My server implementation actually
7291 does not allow router to connect to normal server (it expects
7292 that normal server always initiates the connection to the router)
7293 so the CONNECT command is only good for connecting to another
7296 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7299 or some other client was kicked from the channel.
7301 Implemented the handling of the notify type to both client
7304 Implemented silc_server_send_notify_kicked to send the KICKED
7305 notify. It is used to send it to the server's primary router.
7307 * Implemented the KICK command into server and client.
7309 * Added `query' argument to the silc_idlist_get_client function
7310 to indicate whether to query the client from server or not if
7313 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7314 to indicate that the client is not channel founder.
7318 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Removed the rng context from SilcPacketContext structure and
7321 changed that the packet routine uses the Global RNG API.
7323 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7325 * Added support for quit message that client can "leave" on the
7326 channel when it quits the SILC. It is ditributed inside the
7327 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7329 Added silc_server_free_client_data that will take the
7330 signoff message as argument.
7332 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7334 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Updated parts of the protocol specification to keep it up
7339 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7342 payloads in one packet.
7344 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7345 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7346 use now the new List flag.
7348 * Also deprecated the following packet types: REPLACE_ID,
7349 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7351 * Added list support for Notify packet in server.
7353 * Added silc_server_send_notify_channel_change to send the
7354 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7355 the silc_server_send_replace_id.
7357 * Added silc_server_send_notify_nick_change to send the
7358 NICK_CHANGE notify type. Deprecates the function
7359 silc_server_send_replace_id.
7361 * Added silc_server_send_notify_join to send the JOIN notify type.
7362 Deprecates the function silc_server_send_new_channel_user.
7364 * Added silc_server_send_notify_leave to send LEAVE notify type.
7365 Deprecates the function silc_server_send_remove_channel_user.
7367 * Added silc_server_send_notify_cmode and
7368 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7369 types. Deprecates the silc_server_send_set_mode function.
7371 * Added SERVER_SIGNOFF notify type to indicate that server has
7372 quit. This means that all clients on the channel from that
7373 server will drop. This can be also used when netsplit happens.
7375 Deprecated REMOVE_ID packet type since it is not needed anymore
7378 Added silc_server_send_notify_server_signoff to send the
7379 SERVER_SIGNOFF notify type. Deprecates the function
7380 silc_server_send_remove_id.
7382 Added also silc_server_send_notify_signoff to send the
7383 SIGNOFF notify type.
7385 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7386 SILC protocol from this day on. Changed the protocol
7387 specification as well.
7389 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7390 notify type. It is used between routers to notify about
7391 topic changes on a channel.
7393 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7396 * Partly updated the protocol specification to comply with the
7397 changes now made. It is still though a bit outdated.
7399 * The JOIN notify type now takes one extra argument <Channel ID>.
7400 The packet used to be destined to the channel but now the
7401 JOIN type may be sent as list thus it is impossible to
7402 destine it to any specific channel. By adding this argument
7403 it is again possible.
7405 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7407 * Added CREDITS file. The CHANGES and CREDITS file will appear
7408 in the distribution as well.
7410 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7413 types in the server's silcd/packet_receive.c.
7415 * Implemented CMODE and CUMODE to work in router environment.
7417 * Fixed minor encoding and decoding buglet from the
7418 lib/silccore/silcmode.c.
7420 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7423 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7425 * Changed all SilcConfigServer* and silc_config_server* to
7426 SilcServerConfig* and silc_server_config*, respectively.
7429 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Associated the ID (client or server ID) to the Authentication
7432 Payload to avoid any possibility of forging. Updated the
7433 protocol specification and the code accordingly.
7435 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * The RSA key length is now save to the RsaKey context in the
7438 key generation process in lib/silccrypt/rsa.c. The key length
7439 is now used to figure out the maximum size of the block allowed
7440 to be encrypted/signed.
7442 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7443 is equivalent to the silc_mp_mp2bin but does not allocate any
7446 * Changed silc_mp_mp2bin API to take length argument. If it is
7447 non-zero then the buffer is allocated that large. If zero, then
7448 the size is approximated using silc_mp_sizeinbase, which however
7451 * Created Global RNG API which is global RNG that application can
7452 initialize. After initializing, any routine anywhere in the
7453 code (including library) can use RNG without allocating a new
7454 RNG object. This was done to allow this sort of use of the
7455 RNG in code that has no chance to allocate RNG object. All
7456 applications currently allocate this and many routines in the
7457 library use this. Affected file lib/silccrypt/silcrng.[ch].
7459 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7460 it to use the Global RNG API.
7462 * Defined Authentication Payload into protocol specification that
7463 is used during SILC session to authenticate entities. It is
7464 used for example by client to authenticate itself to the server
7465 to obtain server operator privileges.
7467 Implemented this payload into the lib/silccore/silcauth.[ch].
7468 Implemented also routines for public key based authentication
7469 as the new protocol specification dictates.
7471 Moved definitions of different authentication methods from
7472 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7474 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7475 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7476 silc_pkcs_verify_with_hash functions into the file
7477 lib/silccrypt/silcpkcs.[ch].
7479 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * The client entry's userinfo pointer must be always valid.
7482 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7483 will fail since it requires the userinfo. Now, the userinfo
7484 is allocated as "" if actual userinfo does not exist. Actually,
7485 it must exist and it is totally Ok to drop client connections
7486 that does not announce the userinfo. However, we will make
7487 this workaround for now.
7489 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7490 to return the remote port by socket.
7492 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7494 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7495 SILC_SERVER_PENDING_EXEC and added an new macro
7496 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7497 data or when error occurs while processing the pending command.
7499 Added new argument `destructor' into silc_server_command_pending
7500 and to the SilcServerCommandPending object. This destructor is
7501 now called after calling the pending callback or if error occurs
7502 immediately. If error occurs the actual pending callback won't
7503 be called at all - only the destructor. The destructor may be
7504 NULL if destructor is not needed.
7506 All this applies for client library code as well. Similar
7507 changes were made there as well for the pending commands.
7509 In the client, the application must now allocate the
7510 SilcClientCommandContext with the silc_client_command_alloc
7513 * Added reference counter to the SilcServerCommandContext. Added
7514 function silc_server_command_alloc and silc_server_command_dup
7517 Same type of functions added to the client library for the same
7520 * Removed the cmd_ident from IDListData away since it is now
7521 global for all connections. It is the command identifier used
7522 in command sending and with pending commands. The affected file
7525 * Added reference counter to the SilcSocketConnection objecet to
7526 indicate the usage count of the object. The object won't be
7527 freed untill the reference counter hits zero. Currently only
7528 server uses this, and client ignores it. The client must be
7529 set to use this too later. The affected files are
7530 lib/silccore/silcsockconn.[ch]. Added also the function
7531 silc_socket_dup to increase the reference counter.
7533 This was mainly added because it is possible that the socket
7534 is removed underneath of pending command or other async
7535 operation. Now it won't be free'd and proper DISCONNECTING
7536 flags, etc. can be set to avoid sending data to connection that
7537 is not valid anymore.
7539 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7540 the connection. After that it sets SILC_SET_DISCONNECTED.
7541 It is, however, possible that the socket data is not still freed.
7542 The silc_server_packet_process now checks that data is not
7543 read or written to connection that is DISCONNECTED. The socket
7544 get's freed when the reference counter hits zero.
7546 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7548 * Changed the client operation API: channel_message operation's
7549 `sender' is now the client entry of the sender, not the nickname
7550 and the `channel' is the channel entry, not the channel name.
7552 In the private_message operation the `sender' is now also the
7553 client entry of the sender not the nickname.
7555 Affected file is lib/silcclient/ops.h and all applications
7556 using the client operations.
7558 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Moved the calling of ops->connect() from connect_to_server_final
7561 into receive_new_id functin since that is the point when the
7562 client is actually allowed to send traffic to network. The
7563 affected file is lib/silcclient/client.c.
7565 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7567 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7568 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7569 (if needs broadcasting) instead of broadcasting the packets one
7570 by one which would make a burst in the network traffic.
7572 * Added `broadcast' argument to the functions in silcd/server.[ch]
7573 silc_server_create_new_channel[_with_id] to indicate whether
7574 to send New Channel packet to primary router.
7576 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7578 * Added new function into the silcd/server.[ch] files:
7579 silc_server_create_new_channel_with_id to create new channel with
7580 already existing Channel ID.
7582 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7583 lib/silccore/silcpacket.h. This packet is used t send list of
7584 Set Mode payloads inside one packet. Server uses this to set
7585 the modes for the channels and clients on those channels, that it
7586 announced to the router when it connected to it. The protocol
7587 specification has been updated accordingly.
7589 * The silc_server_new_channel did not handle the packet coming
7590 from normal server as it normally does not send that. However,
7591 when it announces its channels it does send it. Implemented
7592 the support for that.
7594 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7595 into the file lib/silccore/id.h.
7597 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7599 * Fixed memory leaks in the functions silc_idlist_del_client,
7600 silc_idlist_del_channel and silc_idlist_del_server in the file
7601 silcd/idlist.c. All of those leaked like a sieve.
7603 * Fixed some small memory leaks in the client's function
7604 silc_client_notify_by_server.
7606 * Added functions into silcd/server.c: silc_server_announce_clients,
7607 silc_server_announce_channels and silc_server_announce_server.
7608 These functions are used by normal and router server to announce
7609 to its primary router about clients, channels and servers (when
7610 router) that we own. This is done after we've connected to the
7613 These functions effectively implements the following packet types:
7614 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7615 and SILC_PACKET_NEW_ID_LIST.
7617 * Added new functions into the silcd/packet_receive.[ch]:
7618 silc_server_new_id_list, silc_server_new_channel_list and
7619 silc_server_new_channel_user_list to handle the incoming
7620 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7622 * Added support of changing Channel ID in the function
7623 silc_server_replace_id. If the server that announces a channel
7624 to the router already exists in the router (with same name but
7625 with different Channel ID), router is responsible to send
7626 Replace ID packet to the server and force the server to change
7627 the Channel ID to the one router has.
7629 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7630 client that the Channel ID has been changed by the router. The
7631 normal server sends this to the client. Client must start using
7632 the new Channel ID as the channel's ID.
7634 Implemented handling of this new type into lib/silcclient/client.c
7635 into the function silc_client_notify_by_server.
7637 * Added new function silc_idlist_replace_channel_id into the files
7638 silcd/idlist.[ch] to replace the Channel ID.
7640 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Call silc_server_command_identify_check always when processing
7643 the IDENTIFY command in silcd/command.c
7645 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7647 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7648 send keepalive packets. The packet can be sent by clients,
7649 servers and routers.
7651 Added function silc_socket_set_heartbeat into the file
7652 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7653 If not set, the heartbeat is not performed. The actual
7654 heartbeat is implemented in the low level socket connection
7655 library. However, application is responsible of actually
7658 Added silc_server_send_heartbeat to send the actual heartbeat
7659 packet into silcd/packet_send.[ch]. Server now performs
7660 keepalive with all connections.
7662 * Added silc_task_get_first function into lib/silcutil/silctask.c
7663 to return the timeout task with shortest timeout. There was a bug
7664 in task unregistration that caused problems. TODO has been
7665 updated to include that task system must be rewritten.
7667 * The client library will now resolve the client information when
7668 receiving JOIN notify from server for client that we know but
7669 have incomplete information.
7671 * Rewrote parts of silc_server_remove_from_channels and
7672 silc_server_remove_from_one_channel as they did not remove the
7673 channel in some circumstances even though they should've.
7675 * Encryption problem encountered in server:
7677 The LEAVE command used to send the Channel Key packet to the
7678 router immediately after generating it. However, the code
7679 had earlier sent Remove Channel user packet but not immediately,
7680 ie. it was put to queue. The order of packets in the router
7681 was that Channel Key packet was first and Remove Channel User
7682 packet was second, even though they were encrypted in the
7683 reverse order. For this reason, MAC check failed. Now, this
7684 is fixed by not sending the Channel Key packet immediately but
7685 putting it to queue. However, this is more fundamental problem:
7686 packets that are in queue should actually not be encrypted
7687 because packets that are sent immediately gets encrypted
7688 actually with wrong IV (and thus MAC check fails). So, packets
7689 that are in queue should be encrypted when they are sent to
7690 the wire and not when they put to the queue.
7692 However, the problem is that the current system has not been
7693 designed to work that way. Instead, the packet is encrypted
7694 as soon as possible and left to the queue. The queue is then
7695 just purged into wire. There won't be any fixes for this
7696 any time soon. So, the current semantic for packet sending
7699 o If you send packet to remote host and do not force the send
7700 (the packet will be in queue) then all subsequent packets to the
7701 same remote host must also be put to the queue. Only after the
7702 queue has been purged is it safe again to force the packet
7705 o If you send all packets immediately then it safe to send
7706 any of subsequent packets through the queue, however, after
7707 the first packet is put to queue then any subsequent packets
7708 must also be put to the queue.
7710 Follow these rules and everything works fine.
7712 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7714 * Added new function silc_server_remove_clients_by_server to
7715 remove all client entries from ID list when the server connection
7716 is lost. In this case it is also important to invalidate all
7717 client entires as they hold the invalid server entry. This
7718 fixes fatal bug when server has lost connection and will reconnect
7721 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7723 * Made some sanity checks to silc_server_daemonise like to check
7724 whether the requested user and group actually exists.
7726 * Added sanity check to SKE's silc_ske_responder_finish to check
7727 that the public and private key actually is valid.
7729 * Invalidate the client's nickname when receiving Replace ID
7730 packet and the Client ID is being replaced. This means that the
7731 server will query the nickname if someone needs it (client)
7734 * Sort the ID Cache in client library when the ID Cache data
7735 has changed (needs sorting).
7737 * Do not allow for SILC client to create several connections to
7738 several servers. The client does not support windows right now
7739 and generating multiple connections causes weird behaviour.
7741 Irssi-silc client does support windows and can handle several
7742 connections without problems, see: www.irssi.org and SILC plugin.
7744 * Fixed some places where client was added to the IDList. The
7745 rule of thumb is following (in order to get everything right):
7746 If the client is directly connected local client then the
7747 `connection' argument must be set and `router' argument must be
7748 NULL to silc_idlist_add_client function. If the client is not
7749 directly connected client then the `router' argument must
7750 bet set and the `connection' argument must be NULL to the
7751 silc_idlist_add_client function.
7753 * The funtion silc_server_packet_send_local_channel actually did
7754 not check whether the client was locally connected or not. It
7755 does that now. Fixed a bug related to LEAVE command.
7757 * Fixed Remove Channel User payload parsing bug in server's
7758 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7760 * The server's silc_server_save_channel_key now checks also the
7761 global ID list for the channel as it might not be in the local
7762 list. Fixed a bug related to LEAVE command.
7764 * Is this the end of the [<unknown>] buglet that has been lurking
7765 around for a long time? A little for loop fix in server's
7766 silc_server_command_whois_parse that is used by both IDENTIFY
7767 and WHOIS command. At least, this was a clear bug and a cause
7768 of one type of [<unknown>] buglet.
7770 * WHOIS and IDENTIFY commands call the function
7771 silc_server_command_[whois/identify]_check function even if
7772 we are not router server.
7774 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7776 * Added --with-gmp configuration option. If set the GMP
7777 is always compiled in the SILC source tree. If not set then
7778 it is checked whether the system has the GMP3 installed. If
7779 it has then the GMP won't be compiled (the system's headers
7780 and library is used), if it doesn't have it then the GMP is
7781 compiled in the SILC source tree.
7783 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * Changed RSA private exponent generation to what PKCS #1
7786 suggests. We try to find the smallest possible d by doing
7787 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7788 not security fix but optimization.
7790 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Added new config entry [Identity] to fork the server and run
7793 it as specific user and group. A patch from Bostik.
7795 * Imported Dotconf configuration library into lib/dotconf.
7796 This will be used to create the SILC configuration files later.
7797 It will appear in the distsribution after this commit.
7799 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7801 * A big code auditing weekend happening. Auditing code for
7802 obvious mistakes, bugs and errors. Also, removing any code
7805 Removed files for being obsolete:
7807 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7808 inline in the file lib/silcutil/silcbuffer.h)
7810 o lib/silcutil/silcbufutil.c (the header has inline versions)
7812 Changed code to fix possible error conditions:
7814 o The buffer formatting routines now check that the destination
7815 buffer really has enough space to add the data. This applies for
7816 both buffer formatting and unformatting
7817 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7818 unformatting was changed to accomodate following rules:
7819 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7820 sent to the function while XXX_*STRING will not allocate or copy
7821 the data into the buffer. Instead it sets the pointer from the
7822 buffer into the pointer sent as argument (XXX_*STRING used to
7823 require that the pointer must be allocated already). This change
7824 makes this whole thing a bit more consistent and more optimized
7825 (note that the data returned in the unformatting with XXX_*STRING
7826 must not be freed now). The routines return now -1 on error.
7828 o Tried to find all code that use buffer_format and buffer_unformat
7829 and added return value checking to prevent formatting and
7830 especially unformatting errors and possible subsequent fatal
7833 o Changed ske->x and ske->KEY to mallocated pointers in
7834 lib/silcske/silcske.h. Fixed possible data and memory leak.
7836 o Added return value checking to all *_parse* functions. Fixed
7837 many memory leaks as well.
7839 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7840 so that buffer overflows would not happen. All code now also
7841 checks the return value as it can fail.
7843 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7845 * Added reconnection support to server if the normal server looses
7846 its connection to the router (for example if router is rebooted).
7847 The server performs normal reconnection strategy implemented
7848 to the server. Affected file silcd/server.c.
7850 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7852 * Added new packet type SILC_PACKET_SET_MODE that is used to
7853 distribute the information about changed modes (for clients,
7854 channels and clients channel modes) to all routers in the
7855 network. Updated the protocol specification accordingly.
7857 Added functions into silcd/packet_send.c and
7858 silcd/packet_receive.c: silc_server_send_set_mode,
7859 silc_server_set_mode.
7861 Added new files silcmode.[ch] into lib/silccore that implements
7862 the encoding and decoding of Set Mode Payload. Added new type
7863 SilcSetModePayload. Moved the definitions of different modes
7864 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7866 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Oops, a little mistake in server's connection authentication
7869 protocol. The protocol is not ended with FAILURE but with
7870 SUCCESS if the authentication is Ok. :) Affected file is
7873 * Implemented NICK_CHANGE notify handling in server in the file
7874 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7875 the local clients on the channel. After the changing nickname
7876 in router environment snhould work and the [<unknown>] nickname
7877 should appear no more.
7879 The silc_server_replace_id function that receives the Replace ID
7880 payload now sends the NICK_CHANGE notify type also in the file
7881 silcd/packet_receive.c
7883 * Changed WHOIS and IDENTIFY command to support the maximum amount
7884 of arguments defined in protocol specs (3328 arguments). This
7885 fixed a bug that caused problems when there were more than three
7888 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Added extra parameter, command identifier, to the
7891 silc_client_send_command so that explicit command identifier
7894 Changed that ID list routines uses specific command identifier
7895 when sending WHOIS/IDENTIFY requests to the server so that they
7896 can be identified when the reply comes back.
7898 Affected files lib/silcclient/command.[ch],
7899 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7901 * Added `sender' argument to silc_server_packet_send_to_channel
7902 to indicaet the sender who originally sent the packet to us
7903 that we are now re-sending. Ignored if NULL. Affected file
7904 silcd/packet_send.[ch].
7906 * Added some server statistics support in silcd/server_internal.h
7907 SilcServerStatistics structure and around the server code. Also
7908 send some nice statistics information when client is connecting
7911 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7913 * Fixed channel ID decoding in server's JOIN command reply in
7914 silcd/command_reply.c
7916 * Fixed braodcasting of replace ID payload to not to send it if
7917 we are standalone server in silcd/packet_receive.c.
7919 * Fixed all channel message sending routines to not to send
7920 packets to clients that has router set, since they are routed
7921 separately in the same function earlier. Affects file
7922 silcd/packet_send.c and all channel packet sending functions.
7924 * In USERS reply, res_argv[i] are not allocated, the table
7925 is allocated. Thus changed that free the table, not its
7928 * In server's whois_check and identify_check if the client is
7929 locally connected do not send any WHOIS commands - they are not
7932 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7934 * Fixed some minor bugs in client when sending WHOIS command. The
7935 arguments was in wrong order.
7937 * Removed statis function add_to_channel from server in
7938 silcd/command.c that was previously used with the joining but
7941 * Tested USERS command in router environment successfully with two
7942 routers, two servers and two clients.
7944 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7946 * Reorganized the USERS command and command reply in client library
7947 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7948 When the command is given by user we register a pending command
7949 callback that will reprocess the command after the reply has been
7950 received from the server. When reprocessing the packet we then
7951 display the information. Thus, the USERS information is displayed
7952 now in the command callback instead of in the command reply
7953 callback. The processing of the command is same as previously
7954 when server has sent the command reply in the JOINing process.
7956 * Added to USERS command in silcd/command_reply.c to join the client,
7957 we didn't use to know about, to the channel after we've created
7958 a client entry for it. Also, for clienet we did know already still
7959 check whether it is on the channel or not and add it if not.
7961 * Removed silc_server_command_join_notify as the function and its
7964 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7966 * Changed the client's pending command handling to the same as the
7967 server's pending command handling. It is also now possible to
7968 execute command reply functions from other command reply
7969 function as the function callbacks for commands and command
7970 replies are one and same. The pending commands are not static
7971 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7972 in client connection context. Thus, pending commands are server
7973 connection specific as it is convenient.
7975 Changed the function silc_client_command_pending and
7976 silc_client_command_pending_del and added new function
7977 silc_client_command_pending_check. Removed the
7978 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7981 * Added cmd_ident, current command identifier, to the client
7982 connection context in lib/silcclient/client.h to keep track on
7983 command identifiers used in command sending. Client's command reply
7984 function handling now supports the mandatory command identifiers.
7986 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7987 funtions in client to fully support pending command callbacks.
7989 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7990 as one of the arguments to the application in the command reply
7993 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7994 before first releasing SILC but came back. Now it is removed again
7995 and should come back nomore. The FORWARDED flag was used only
7996 by the JOINing procedure by forwarding the command packet to router.
7997 Now, the JOINing procedure has been changed to more generic (due
7998 to various router environment issues) and FORWARDED is not needed
7999 anymore for anything. The protocol specification is yet to be
8002 Now, removed silc_server_packet_forward from server and the flag
8003 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8005 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8007 * Renamed NAMES command to USERS command. The NAMES was named that
8008 due to historical reasons. Now it is renamed. Also, rewrote
8009 parts of the USERS command. The nickname list is not sent anymore
8010 by the server. Only Client ID and mode lists are sent in the USERS
8011 command. Changed this also to the protocol specification.
8013 The client now resolves the names and stuff after it receives
8014 the USERS list from the server when joining to the channel.
8016 * WHOIS and IDENTIFY commands has been changed to support multiple
8017 Client ID's per command. One can now search for multiple users
8018 in the network by sending only one WHOIS or IDENTIFY command.
8019 Changed the code and the protocol specifications.
8021 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8022 uses silc_server_command_whois_parse to parse the request. */
8024 * If normal server, do not parse the WHOIS and IDENTIFY requests
8025 before sending it to the router. Saves some time.
8027 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8029 * Fixed JOIN command on client library. Wrong number of arguments
8030 used to crash the client.
8032 * Added silc_server_channel_has_global function to check whether
8033 channel has global users or not.
8035 * Added silc_server_channel_has_local function to check whether channel
8036 has locally connected clients on the channel.
8038 * The silc_server_remove_from_one_channel now checks whether the
8039 channel has global users or not after given client was removed from
8040 the channel. It also checks whether the channel has local clients
8041 on the channel anymore. If it does not have then the channel entry
8042 is removed as it is not needed anymore.
8044 * The silc_server_notify now checks on JOIN notify whether the joining
8045 client is one of locally connected or global. If it is global then
8046 the channel has now global users on the channel and that is marked
8047 to the channel entry. Also, it now saves the global client to
8048 global list who is joining and JOINs it to the channel. This is
8049 for normal server, that is.
8051 Changed silc_server_send_notify_on_channel,
8052 silc_server_packet_relay_to_channel and
8053 silc_server_packet_send_to_channel check if we are normal server
8054 and client has router set (ie. global client) do not send the
8055 message to that client, as it is already routed to our router.
8057 * Implemented LEAVE notify type handling in silc_server_notify
8060 * Tested LEAVE command in router environment successfully. Tested
8061 with two routers, two servers and two clients.
8065 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8067 * Implemented SIGNOFF notify type handling in silc_server_notify
8070 * silc_server_remove_id now removes the client entry from all channels
8071 it has joined and thusly sends SIGNOFF notify type.
8073 * Rewrote the NAMES list generation in server by removing two excess
8074 loops. The lists are created now inside one loop.
8076 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8078 * silc_server_remove_channel_user checks now also global list
8079 for channel and client.
8081 * silc_server_new_channel_user checks now both local and global
8082 list for channel and client. Fixed a bug in client id decoding.
8083 Used to decode wrong buffer.
8085 * silc_server_channel_message checks now both local and global
8086 list for channel entry.
8088 * Tested channel joining (hence JOIN) in router environment
8089 successfully. Tested with two routers, two servers and two
8092 * Tested channel message sending in router environment successfully.
8094 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Added silc_server_save_channel_key into server.[ch] to save the
8097 received channel key in Channel Key payload processing. It is
8098 also used in JOIN command reply handling.
8100 Equivalent function silc_client_save_channel_key added into
8101 client.[ch] into client library.
8103 * Changed JOIN command reply to send information whether the channel
8104 was created or not (is existing already) and the channel key
8105 payload. Changed protocol specs accordingly.
8107 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8108 the request was sent by ID and not by nickname. Crashed on
8111 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8113 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8114 now correctly save the received data.
8116 * silc_server_free_sock_user_data now notifies routers in the
8117 network about entities leaving the network.
8119 At the same time implemented functions silc_server_remove_id
8120 and silc_server_send_remove_id to receive and send REMOVE_ID
8121 packets. The packet is used to notify routers in the network
8122 about leaving entities. The ID removed will become invalid in
8125 * Added function silc_idlist_del_server into server. Removes and
8126 free's server entry from ID list.
8128 * silc_server_private_message function now checks, if we are router,
8129 that the destination ID really is valid ID, naturally.
8131 * In router when NEW_ID packet is received (for new client) the
8132 hash of the Client ID is saved in the ID Cache but the
8133 client->nickname is set to NULL, instead of putting the hash
8136 IDENTIFY command now also checks that client->nickname must be
8137 valid. If it is not if will request the data from the server who
8138 owns the client. Added new function
8139 silc_server_command_identify_check.
8141 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8142 to set the command to already allocated Command Payload.
8144 * Tested private message sending in router environment with two
8145 routers, two servers and two clients. Fixed minor bugs and now
8148 * Fixed segfault from client's NAMES command. Used to crash if
8151 * Forwarded packets must not be routed even if it is not destined
8152 to the receiver. Changed server code comply with this.
8154 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Added `require_reverse_mapping' boolean value to ServerParams
8157 structure. If TRUE (not default) the server will require that
8158 the connecting host has fully qualified domain name.
8160 If the reverse mapping is not required and hostname could not be
8161 found the IP address is used as hostname.
8163 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8165 * Implemented version string checking to both client and server.
8166 The check is incomplete currently due to the abnormal version
8167 strings used in development version of SILC.
8169 * Changed all command functions in server to use the new
8172 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8174 * Changed char *data to unsigned char *data in ID Cache system to
8175 support binary data as ID Cache data. Changed code to support
8176 binary data in lib/silccore/idcache.c.
8178 * Renamed silc_server_packet_relay_command_reply to
8179 silc_server_command_reply as it is normal packet receiving
8180 function. Rewrote the function to accept command replys for
8181 servers and not only for clients.
8183 * Mark remote router always as registered server if we are connecting
8184 to it. Otherwise, commands sent by the router to us are ignored.
8186 * All ID List find routines now returns the ID Cache Entry pointer
8187 as well if requested.
8189 * WHOIS command works now in router environment, tested with two
8190 routers, two servers and two clients.
8192 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8193 in router environment (as it is almost equivalent to WHOIS) but
8194 hasn't been tested thoroughly. Added new functions:
8196 silc_server_command_identify_parse
8197 silc_server_command_identify_send_reply
8198 silc_server_command_identify_from_client
8199 silc_server_command_identify_from_server
8201 * Disabled route cache adding because adding two different ID's with
8202 same IP replaces the old cache entry thus giving wrong route.
8203 The entry->router->connection is always the fastest route anyway
8204 so route cache may not be needed. Of course, new routes maybe
8205 established after receiving the ID when the entry->router->connection
8206 might not be anymore the most optimal.
8208 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Add route cache for received ID for fast routing.
8212 * Added silc_server_packet_route to route received packet on router
8213 that is not destined to us.
8215 * Renamed silc_server_get_route to silc_server_route_get.
8217 * Added id_string and id_string_len fields into SilcServer to
8218 include encoded ServerID for fast comparing without excess
8219 encoding of the ID's.
8221 * Cleaned up WHOIS command on server side. Added following static
8224 silc_server_command_whois_parse
8225 silc_server_command_whois_check
8226 silc_server_command_whois_send_reply
8227 silc_server_command_whois_from_client
8228 silc_server_command_whois_from_server
8230 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8231 arguments in command replies. All command functions should be
8232 updated to use this macro.
8234 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8236 * Minor typo fixes on command reply handling on server.
8238 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8240 * Added silc_server_command_add_to_channel internal routine to add
8241 the client to the channel after router has created the channel and
8242 sent command reply to the server.
8244 * Added generic silc_server_send_command to send any command from
8247 * Use static buffer with ID rendering instead of duplicating data.
8249 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8251 * Fixed a channel user mode bug when joining to a channel server gave
8252 everybody channel founder rights, oops.
8254 * We mark ourselves as the router of the incoming server connection
8255 if we are router ourselves. This way we can check in some packet
8256 sending functions whether it is locally connected server. For
8257 incoming router connections we put NULL.
8259 * For router sending packets locally means now always sending the
8260 packet cell wide; to local clients and local servers. For normal
8261 server sending packet locally means sending it to only local
8264 * Fixed the JOIN command to really work in router environment. If the
8265 channel is created it is always created by the router. Router is
8266 also responsible of making the initial joining to the channel,
8267 sending JOIN notify to the sending server and distributing
8268 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8269 does not exist server doesn't do anything else but forward the
8270 command to the router which performs everything.
8272 * Added silc_server_send_channel_key function to send the Channel Key
8275 * Added silc_server_create_channel_key to create new channel key. The
8276 channel key is now re-generated everytime someone joins or leaves
8277 a channel, as protocol dictates. Note: channel->key_len is the
8280 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8282 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8283 packet_receive.[ch] to separate packet sending and receiving
8284 routines. The server.[ch] now includes everything else including
8285 actual packet processing (writing and reading data) and other
8288 Renamed silc_server_private_message_send_internal to
8289 silc_server_send_private_message. The routine is still though
8290 used only to relay private messages as server does not send
8291 private messages itself.
8293 Renamed silc_server_new_channel to silc_server_create_new_channel
8294 and added new function sicl_server_new_channel that handles the
8295 incoming New Channel packet. Added also new sending function
8296 silc_server_send_new_channel to send New Channel Payload.
8298 * Added new function silc_server_notify to process incoming notify
8299 packet to the server/router. Server may then relay the notify
8300 to clients if needed.
8302 * Added new function silc_server_new_channel_user to process incoming
8303 New Channel User packet. Router will redistribute the packet and
8304 send JOIN notify to its local clients and locally connected servers
8305 if needed. Normal server will send JOIN notify to its local client
8306 on same channel when received this packet. Added also corresponding
8307 sending function silc_server_send_new_channel_user to sent the
8310 * Added boolean route argument to send_notif_to_channel and
8311 packet_send_to_channel functions to attempt to route the packet
8312 if it is TRUE and send only locally if it is FALSE.
8314 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8316 * silc_server_replace_id now broadcasts the received replace ID
8317 packet if it is not broadcast packet already. The router must
8318 broadcast to inform other routers about changed ID.
8320 * Added backpointer to server's router into SilcServer context in
8321 silcd/server_internal.h.
8323 * Fixed silc_server_packet_broadcast to send correct broadcast
8326 * The channel key is now distributed to the local client as soon
8327 as it is received from the router (in router environment) so that
8328 no other packet may be sent for the channel until client has
8331 * silc_server_remove_channel_user now broadcasts the received
8332 Remove Channel User packet if it is not broadcast packet already.
8333 The router must broadcast to inform other routers about removed
8336 * Added users field into SilcPacketContext that is a reference count
8337 of the context. One can increase the reference count by calling
8338 silc_packet_context_dup which is now changed to just increase the
8339 reference count instead of duplicating the data. The reference
8340 count is decresed by calling silc_packet_context_free that will
8341 free the data after the reference count hits zero.
8343 For now on the packet context and everything allocated into it
8344 (including the raw packet from network) must be freed by calling
8345 the new silc_packet_context_free function. Added also new function
8346 silc_packet_context_alloc that must be used now to allocate the
8347 context. This also means that if a routine is asynchronous from
8348 silc_[client/server]_packet_parse_type the packet context must
8349 be duplicated by calling silc_packet_context_dup. Otherwise it
8350 gets free'd after silc_[client/server]_packet_parse_type returns.
8351 Also, one must remember that if packet is duplicated then its
8352 reference count must be decresed by calling the free function as
8353 many times as it was duplicated.
8355 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8356 from both client and server.
8358 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8360 * Made joining to a channel working in router environment.
8362 * Cleaned up JOIN command on server side and create function
8363 silc_server_command_join_channel internal routine to make the
8366 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8368 * Changed silc_command_pending list to SilcDList. Also, added
8369 `ident' field to SilcServerCommandPending structure to identify
8370 the reply and to call correct callback.
8372 Added silc_server_command_pending_check function to replace the
8373 corresnponding macro. The silc_command_pending list is not
8376 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8377 to set identifier to previously allocated Command Payload. It
8378 is used to set identifier for command when resending Command
8381 * Added silc_command_payload_encode_payload to encode Command
8382 Payload buffer from SilcCommandPayload structure.
8384 * Added silc_argument_payload_encode_payload to encode Argument
8385 payload buffer from SilcArgumentPayload structure.
8387 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8389 * Changed WHOIS command to support router connection on server side.
8390 The whois request is always sent to router unless the server is
8391 standalone server. After server has received the reply from the
8392 router will it send the reply to the client.
8394 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8395 broadcast received broadcast packet. The function is used only
8396 by router. The broadcast packet is always sent to the router's
8399 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8400 render given ID to printable string, for log files for example.
8402 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8404 * Made basic router to router connections working. At least they
8405 can now connect to each other but nothing really works the way
8406 they are supposed - yet.
8408 * Added new initiator token to RouterConnection configuration
8409 file in silcd/serverconfig.[ch]. It is used to tell whether we
8410 are the initiator to the remote router or whether we'll expect
8411 the other end to connect.
8413 * Moved registering of listener task to silc_server_init, hence
8414 the server starts listenning as soon as it is run, even if it
8415 does not have connections to other routers. Let's see how well
8418 * Changed default connection retry timeouts for more suitable in
8421 * Removed cipher and such arguments from silc_idlist_add_client
8422 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8423 Added new function silc_idlist_add_data to add the keys and stuff
8426 * Added SilcIDListData structure and added it to SilcClientEntry
8427 and SilcServerEntry as their first field in the structure. This
8428 way we can explicitly cast the ID entries to the SilcIDListData
8429 structure and get common data for the entries. In past, we had
8430 to first check what type of connection it is and then cast it to
8431 correct ID entry type. Now, we can directly cast the opaque
8432 pointer to the SilcIDListData (no matter what ID entry it actually
8433 is) and get the data needed.
8435 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8438 in some circumstances even if threre were timeout tasks, though not
8439 IO tasks, but tasks anyway. Now fixed.
8441 * Defined SilcServerConnection structure to hold connection specific
8442 stuff about directly connected servers and routers. The definition
8443 is currently in silcd/server_internal.h. I thought about having
8444 a bit more important role fro this struct but for now it is used
8445 only when connecting to other server (or router actually).
8447 * Added connecting retry support in server when connecting to
8448 router(s). The retry feature implement exponential backoff
8449 algorithm. Also, added SilcServerParams structure to hold default
8450 parameters for server. For now, it include these retry settings
8451 and are hard coded. After server is moded to be as Silc Server
8452 Library this structure will be more important.
8454 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8456 * Changed client librarys channel->clients table to SilcList and
8457 changed code accordingly.
8459 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8461 * Changed client's channel table to SilcList and changed code
8462 accordingly. Also changed SilcChannelClientEntry to include back-
8463 pointer to the channel so that client entry can use that structure
8464 as list as well and we have fast cross-reference to the channel.
8465 This change dramatically decreased the complexity of channel
8466 handling with client entry and vice versa (removed one extra
8467 loop when searching for channel entry from many functions).
8469 * Changed server->sim from table to SilcDList and changed code
8472 * NAMES command can now be used from user interface. It will show
8473 the user list on the channel, neatly.
8475 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8476 Code now saves realname of the user if it becomes available.
8478 * Renamed configure.in to configure.in.pre and made ./prepare
8479 script to automatically add correct version string to
8480 configure.in which it creates from configure.in.pre.
8482 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8484 * NAMES command reply now shows users mode with the nickname when
8487 * Moved silc_client_ch[u]mode[_char] functions from
8488 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8489 place sucks, they are utility functions and should be in some
8492 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8494 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8497 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8501 * Added TRQ (efficient deque and list library) into lib/trq. This is
8502 a very good list library that is currently used in the SILC. Defined
8503 SilcList API over the library because I didn't like the API very
8504 much. See lib/trq/silclist.h for the API and examples of how to
8505 use the API. Fixed various places in the code to use the new
8506 SilcList API. The SilcList is meant for lists that has a structure
8507 already defined as a list. It is not suitable to add just some
8508 context to the list (in TRQ, the context is the list actually).
8510 So, I defined SilcDList that can be used for the purpose where
8511 predefined list structure does not exit. This can be used as
8512 such list. Now some context just can be added to the SilcDList.
8513 Currently this list is not used in the SILC just yet, though there
8514 are a lot places where this can replace dynamically allocated
8515 tables and I will fix these places, later, to use SilcDList.
8516 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8517 and use TRQ internally).
8519 Also fixed some annoying warning messages that the original TRQ
8520 code generated. Also minor changes to TRQ's Makefile.in.
8522 * Added support for querying by Client ID to both WHOIS and
8523 IDENTIFY commands into server, as required by the protocol.
8525 * Removed method function pointers from SilcBuffer structure. They
8526 weren't used to anything and just increased the context size for
8527 no good reason. This change also made silc_buffer_alloc and
8528 silc_buffer_free functions inline functions.
8530 * Disabled command flooding detection support until it's fixed so
8531 that it accepts commands in but does not execute them more than once
8534 * Added silc_net_localhost(), to return local hostname, into
8535 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8536 that must be initialized before calling silc_client_init.
8538 * Added new function: silc_server_send_notify_on_channels to send
8539 notify messages to all channels client has joined. It is assured
8540 that the message is sent only once per client.
8542 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8543 lib/silcutil/silcutil.[ch] as silc_format function. The new
8544 function is generic and is used by server as well, not only by
8545 the logging routines.
8547 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8548 the provided version string was not acceptable. Added new function:
8549 silc_ske_check_version into lib/silcske/silcske.h. The function
8550 must be implemented by the application (client or server) and it
8551 does not reside in the SKE library. The function checks the version
8552 string remote end sent.
8554 * Added back pointers (to opaque context and to SilcSocketConnection)
8555 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8557 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8558 duplicate packet context structure.
8560 * Changed `notify' client operation to send same arguments as client
8561 receives from server except for ID's. ID's are mapped to correct
8562 ID entry and that is returned. Also, if channel entry is not sent
8563 by server but the notify is for channel the channel entry is sent
8564 to application (otherwise application doesn't know that it is for
8565 channel (library gets it from packet's Destination ID)).
8567 * Added silc_client_remove_from_channels into client library to
8568 remove a client from all channels it has joined to. Used when
8569 received SIGNOFF notify from server. Added also new function
8570 silc_client_replace_from_channels to replace old ID entry with
8571 new ID entry on all channels. Used when received NICK_CHANGE
8574 * Fixed ID Cache list handling in silc_idlist_get_client in
8575 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8576 to get (or query) client by ID.
8578 * Updated TODO list.
8580 * Added connection authentication status message defined by the
8581 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8582 support for these into the code in client and server side.
8584 * Added generic function silc_client_send_command to send any command
8585 with variable argument list. Application should use this function
8586 to send commands if the command functions provided by the library
8587 does not suite for the application's user interface needs.
8589 * Added new `failure' client operation. Application is notified about
8590 received failure packet if client is executing a protocol. In this
8591 case the protocol's execution has failed.
8593 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8594 is required by the protocol.
8596 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8597 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8600 * Added status flag to SilcSKE object to indicate realtime status
8601 of the SKE protocol.
8603 * Application receives now exactly same command reply arguments as
8604 the library receives from server. However, if ID is received the
8605 corresponding ID entry is returned to the application (eg. Client
8606 ID is mapped to correct SilcClientEntry entry and that is returned).
8607 Changed command_reply client operation due to this change.
8609 * Changed all ID's in commands and in command replys as ID Payloads.
8610 Change affected both client and server side codes.
8612 All ID's sent in SILC network (with execption of ID's in SILC
8613 Packet header) are sent in ID Payload to support variable length
8616 * Server now notifies nick changes and notifies all clients on
8617 the channels about the new nickname (about the new Client ID,
8620 * Implemented CMODE command to change channel modes. Supports all
8621 channel modes defined by the protocol specs except ban and invite
8622 lists. (Also, private channel key mode is supported but support for
8623 setting private channel key in client is missing, thus, this mode
8624 has no effect on client side (except that server requires that the
8625 client uses private channel key and normal channel traffic does not
8628 Also, invite mode works per se, but INVITE command does not work
8629 yet correctly, so you can set channel as invite only channel but
8630 inviting clients to the channel does not work (it is yet to be
8631 thought what's the best way to do it).
8633 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8634 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8635 Implemented CUMODE command to change user's mode on the channel.
8636 Supports all modes defined by the protocol specs.
8638 * Added NAMES command reply to return users modes on the channel.
8640 * Removed unnecessary and slow ciphers from lib/silccrypt.
8642 * Set SO_KEEPALIVE option to connection sockets by default.
8644 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8646 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8647 redefined the Notify Payload into protocol specs.
8649 * Added silc_id_payload_parse_id to get ID directly from raw
8652 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8654 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8655 accept searching by Client ID as well.
8657 * Added support for LEAVE and SIGNOFF notify types in client library.
8659 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8660 to parse ID Payload from raw data.
8662 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8664 * Added flags parameter into silc_ske_assemble_security_properties
8665 function in lib/silcske/silcske.[ch].
8667 * Changed notify client operation to fit better for notify messages
8668 sent by server. The notify payload received from server is now
8669 passed to the application (after parsing it to SilcNotifyPayload).
8670 It is application's responsibility to retrieve the arguments
8671 from the payload and show the message the way it wants. The message
8672 sent by server is implementation specific.
8674 * Changed public keys to comply with the protocol specification.
8675 Old public keys are not supported anymore and are not compatible.
8677 * Removed nickname from Channel Payload as the latest draft removed
8678 it. The client must resolve the nickname from the NAMES command
8679 reply received when it joined the channel.
8681 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8683 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8685 * Fixed some errors in protocol specification drafts.
8687 * Created lib/silccore/silcnotify.c to implement Notify Payload
8688 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8689 generic payloads described by protocol specifications. The file
8690 includes implementations for ID Payload and Argument Payload.
8692 * Changed Command Payload implementation to use the new Argument
8693 Payload. Changed command_xxxx_payload to command_payload_xxxx
8694 to comply with SILC coding conventions.
8696 * Added suppport for Argument Payload handling in Notify Payload
8697 implementation as protocol requires it. Added the new support
8698 into server and client lib as well.
8700 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8702 * Added support for multiple nicknames on same channel. [n] is
8703 added locally to the nickname if there are more than one same
8704 nicknames on the channel.
8706 * Server now sends all nicknames that matched WHOIS request.
8707 Client also shows the list received from server.
8709 * Added TOPIC command to client side. User can now set and show
8710 current topic on channel.
8712 * Added MOTD command to client and server. Also, server sends the
8713 motd when client connects to the server.
8715 * Changed version strings to comply ISO 8601.
8717 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8719 * Fixed protocol error handling in client library. It should now
8720 cope even if the SKE fails for some reason.
8722 * Made new protocol specification drafts for submitting to IETF.
8724 * Implemented TOPIC command to server in silcd/command.c.
8726 * Added two new notify types into lib/silccore/silcnotify.h:
8727 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8728 notify nickname change and topic setting/change on a channel.
8730 * API change of command_reply operation in client library. The
8731 application gets now the status type received from server as well.
8733 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8735 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8737 * Cras fixed and optimized the packet handling even further and
8738 it should work now. Minor change to the prototype of function
8739 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8741 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8743 * Added new function into lib/silcutil/silcschedule.[ch]:
8744 silc_schedule_with_fd to select() a specified fd. The function
8745 returns after timeout expires or data arrives or goes. The
8746 function is used by packet routines to wait that all data is
8747 received from network.
8749 * Fixed data reading from network in lib/silccore/silcpacket.c.
8750 The code now assures that all data is read from the fd and then
8751 continues packet processing. This was a bug fix since the code
8752 used to drop some data in some circumstances.
8754 * Added new function into lib/silcclient/client.[ch]:
8755 silc_client_start_key_exchange to start key exchange after
8756 connection has been established to server. The code internally
8757 now uses this funtion but its main purpose was to provide it
8758 for applications that perform their own connecting. After
8759 application has created a connection it merely calls this
8760 function to start the key exchange between client and server.
8761 The library takes care of everything else after that.
8763 Updated also lib/silcclient/README to explain the usage of
8766 * Do not send to application information that connection has
8767 been established. Application gets notified it by connect
8770 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8772 * Applied cras's patch to add silc_schedule_one function. The
8773 function runs scheduler once and returns.
8775 * Fixed the scheduler after cras messed it up. The timeout
8776 handling works now as it's supposed to work.
8778 * Added into lib/silccore/ silcnotify.h to include notify
8779 message types support. Changed silc_server_send_notify*
8780 functions, in server.[ch], to support those new notify types.
8781 Added the support for the notify types into client library,
8782 as well. Added new notify client operation into ops.h in
8785 * Changed silc_server_packet_send_to_channel to send normal
8786 packets instead of just channel message packets. The function
8787 is now used to send the notify packets to channels. It is not
8788 used to send channel message packets anymore, as server never
8791 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8792 va_arg()s as it seems to require it nowadays. I guess, if SILC
8793 is compiled with older va_arg() the new code should work anyway.
8795 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8797 * Splitted core library. Core library (lib/silccore) includes
8798 now only SILC protocol specific core (and common) components.
8799 Created new utility library (lib/silcutil) that includes more
8800 generic purpose stuff. The stuff for util library was taken
8801 from the old core library. This was minor and easy split.
8803 * Created SILC Client Library (lib/silcclient) that includes
8804 implementation of the SILC client without user interface. This
8805 was major move from silc/ directory. The code has been changed
8806 so that it is transparent towards the user interface. The
8807 silc/ directory includes now the same user interface as before
8808 and it uses the new client library. Read lib/silcclient/README.
8809 Basicly, the client library performs everything else related
8810 to SILC except user interface handling. Also, configuration
8811 files are considered to be part of user interface and library
8812 does not handle them.
8814 This change also changed a lot of structures, function naming etc.
8815 Most important change was that SilcClientWindow object was
8816 renamed to SilcClientConnection in the client library. Created
8817 also new file lib/silcclient/ops.h. Also added new files
8818 silc/local_command.[ch] and silc/client_ops.[ch].
8820 All these changes were made to make it easier for user interface
8821 designers to create what ever user interface for the SILC client
8824 It is also expected that the server will be moved to lib
8825 directory as well and SILC Server Library will be created;
8826 sometimes in the future.
8828 * Removed Local commands from lib/silccore/silccommand.h as
8829 they are application specific and new client library does not
8830 handle any of those anymore.
8832 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8833 old client implementation in silc/.
8835 * Added support for callback functions in SILC_LOG_* macros.
8836 Application can now set its own callbacks that will be called
8837 instead of using the default functions that will always print
8838 the debug messages to stderr (or stdout). Also, debugging can
8839 now be disabled by setting silc_debug to FALSE and re-enabled by
8840 setting it to TRUE. Note, that logging will still work even
8841 if debugging is disabled.
8843 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8844 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8845 silc_log_reset_debug_callbacks.
8847 * To enable debugging in silc client one must give now -d
8848 option on command line.
8850 * Changed silc_schedule_init to automatically allocate task queues
8851 if they are not allocated before calling it.
8853 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8855 * Added GMP 3.1 into math library.
8857 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8859 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8860 a channel in SILC network. The packet is used by servers and
8861 routers to notify other routers that user has left a channel.
8862 This little feature was missing until now. Added the feature
8863 to protocol specification as well.
8865 Added functions: silc_server_send_remove_channel_user and
8866 silc_server_remove_channel_user into server.[ch].
8868 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8869 lib/silccore/silcpacket.h. However, they are not implemented
8872 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8874 * Fixed joining to a channel and sending channel messages
8875 between server and router. The channel message sending should
8876 now work inside a cell.
8878 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8880 * Fixed the private message sending between server and router.
8881 The private message sending should now work inside a cell.
8883 * Added silc_server_replace_id into server.[ch] to replace
8884 existing ID in the SILC network.
8886 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8887 and silc_idlist_replace_server_id into idlist.[ch] in server.
8889 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8891 * Fixed the server to server connections. Server can again now
8892 connect to router. Router to router connections probably does
8895 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8897 * Added dynamic protocol registering support. Now protocols can
8898 registered and unregistered on the fly. Patch by cras.
8900 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8902 * Added lib/contrib directory to hold routines that some platforms
8903 don't have but are needed by SILC.
8905 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8906 into lin/contrib to provide getopt() and getopt_long() for
8907 those who don't have it.
8909 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8911 * Added AWAY command to client. When away message is set and
8912 client receives a private message packet the client automatically
8913 replies to the sender with the away message.
8915 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8916 bug seemed to be the cause of recent problems when compiling
8919 * Added version detection support to SKE protocol specification
8920 and added the new changes to the SKE implementation as well.
8921 There were other minor changes in the SKE protocol as well.
8923 Many changes in lib/silcske/silcske.[ch] and in
8924 lib/silcske/payload.[ch].
8926 * Added ^U functionality, clear input line. Patch from cras.
8928 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8930 * Mainly small bugfixes on core library. Fixed some debugging
8931 logging and buffer overflow in silclog.c.
8933 * Updated config.sub and config.guess on the distribution tree.
8935 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8937 * Added command lagging support in server. Client may execute
8938 commands now only once in two seconds.
8940 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8942 * Optimized packet reception. MAC computation and checking is now
8943 also more optimized. A lot previously duplicated code is now
8944 used as generic by both client and server.
8946 * Fixed key pair generation in clientutil.c
8948 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8950 * Added into lib/silccore/silcbufutil.[ch] new function;
8951 silc_buffer_realloc.
8953 * Moved generic packet sending/encryption functions to
8954 lib/silccore/silcpacket.[ch] from client and server. Some
8955 rewriting of the functions.
8957 * Moved all generic packet reception/decryption functions to
8958 lib/silccore/silcpacket.[ch] from client and server. The
8959 packet processing is now much cleaner in both client and server.
8960 These were major changes in both client and server.
8962 * Created many common functions in server to do packet sending.
8963 Previously code were duplicated a lot, this has been removed
8966 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8968 * Rewrote major parts of the ID cache system. Don't know
8969 whether it is better now or not but at least the API is more
8972 * Major rewrite on ID cache stuff on client because of the ID
8973 cache API changes. Added idlist.c to client.
8975 * Also major rewrite on ID cache stuff on server as well.
8976 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8977 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8978 in hand, instead they are all put into the ID cache system now.
8979 All server_idlist_* routines uses ID cache now instead of
8980 traversing its own lists (those lists does not exist anymore).
8981 SilcIDList though still exists. Also, SilcXXXEntry's are
8984 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8986 * Finally made the SKE implementation compliant to the protocol
8987 specification. All mp integers are now binary encoded as
8988 opposed being HEX encoded.
8990 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8993 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8994 functions: silc_[encode/decode]_pem. Also added function
8995 silc_encode_pem_file to PEM encode with newlines ('\n') for
8998 * SILC public keys are now encoded either PEM or binary. Same
8999 option is for private keys as well. By default private keys
9000 are binary encoded and public keys PEM encoded. Silly HEX
9001 encoding were removed.
9003 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9004 function to create fingerprints.
9006 * Fixed a bug in SHA1; does not change the original data anymore.
9008 * Partly implemented INFO command on client and server side.
9009 Fixed CLEAR command. Changes to SERVER command; show current
9010 server(s) when giving command without arguments. Added
9011 VERSION command to client.
9013 * Added check to server that unregistered connections cannot
9014 execute commands (unless it is specificly allowed).
9016 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9018 * Fixed screen refresh.
9020 * Fixed channel joining bug from client. On some circumstances
9021 client tried to join to a channel it had already joined.
9023 * Added public key verification process into client's protocol.c.
9024 The client now verifies the public key from user and saves
9025 it into ~./silc/serverkeys/ directory.
9027 Added into: clientutil.[ch]: silc_client_verify_server_key.
9029 * Changed SKE protocol's silc_ske_initiator_finish function
9030 to accept callback function that verifies the received public
9031 key. Removed old silc_ske_verify_public_key function.
9033 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9035 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9036 silc_pkcs_private_key[_data]_set.
9038 * Made the password and public authentication more cleaner in
9039 server's protocol.c.
9041 * Removed historic and obsolete protocol `channel_auth' from
9042 both client and server.
9044 * Removed wrong way of sending command status messages from
9045 server to client in server's command.c. The old way violated
9046 protocol specification.
9048 Changes to silccore/silccommand.[ch]: removed
