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

1086 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1087 server config parsing code more readable.
1089 Fixed a bug in the fetch_logging() config callback.
1091 Affected files is silcd/serverconfig.c.
1093 * Drop root privileges when started in foreground. Don't drop them
1094 if debugging also. Affected file is silcd/silcd.c.
1096 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Added more IM-like features by introducing new user modes
1099 for setting various presence information. Added new modes:
1100 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1101 specs and code. Protocol TODO #19. Affected files are
1102 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1103 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1105 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * Added STATS command to the protocol after all, to return
1108 various statistical information about the network. It can
1109 be used by clients to retrieve statistical information, and
1110 servers may use it to to fetch cell and network wide
1111 statistics from router. Updated the protocol specs and
1112 implemented it to the server. Protocol TODO #16.
1113 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1114 silcd/command_reply.[ch].
1116 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1118 * The LIST command reply in client libary now adds new channel
1119 entry if the returned channel doesn't exist yet in cache,
1120 and returns the channel entry to the application in the
1121 command_reply client operation. Affected file is
1122 lib/silcclient/command_reply.c.
1124 * Changed the channel message payload's MAC generation to
1125 include the IV in the MAC as well. This way all relevant
1126 parts of the channel message payload are authenticated also
1127 with the channel message MAC (and not only by packet MAC).
1128 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1129 Affected file is lib/silccore/silcchannel.c.
1131 * Fixed the SKE to save the remote version, since the
1132 silc_ske_parse_version mistakenly checked wrong version,
1133 after it replaced the start payload. Affected files are
1134 lib/silcske/silcske.[ch].
1136 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

1140 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1141 Affected files lib/silcutil/silcstrutil.[ch].
1143 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1144 files are lib/silcutil/silcstrutil.[ch].
1146 * Defined that the security property fields in SKE SHOULD be
1147 UTF-8 encoded, defined that version string MUST be US-ASCII
1148 encoded, defined that passphrases sent in connection
1149 authentication protocol MUST be UTF-8 encoded. Implemented
1150 these to the client and server. Defined also that other
1151 passphrases sent in the protocol MUST be UTF-8 encoded.
1152 Affected files are lib/silcske/silcske.c,
1153 lib/silcclient/protocol.c, silcd/protocol.c,
1154 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1156 * Changed the silc_client_close_connection interface to not
1157 need the SilcSocketConnection which should not be visible
1158 to application. Affected files are lib/silcclient/client.c
1159 and lib/silcclient/silcclient.h.
1161 * Rewrote the text for Private Message Key Payload in the
1162 protocol specification. Protocol TODO #11.
1164 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1166 * Upgraded the protocol version to 1.1, updated protocol specs
1169 * Added the nickname as new argument to NICK_CHANGE notify and
1170 added it to protocol specs and implemented it to client and
1171 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1172 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1173 lib/silcclient/client_notify.c.
1175 * Added the killer's client ID to the KILLED notify and added
1176 it to protocol specs and implemented it to client and server.
1177 Protocol TODO #13. Affected files are silcd/command.c,
1178 silcd/packet_receive.c, packet_send.[ch],
1179 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1180 The killer's client entry is now returned to application in
1181 the `notify' client operation.
1183 * Fixed the Max Argument fields that had too large value set
1184 in the protocol specs. Protocol TODO #14.
1186 * Added the LEAVE command reply to return the ID of parted
1187 channel. Updated protocol specs and implemented it to the
1188 client and server. Protocol TODO #15. Affected files are
1189 silcd/command.c, lib/silcclient/command_reply.c. The channel
1190 entry is now returned to application in the `command_reply'
1193 * Rewrote the version SKE version checking in client libary
1194 and in server to use the silc_parse_version_string. Affected
1195 files are lib/silcclient/protocol.c, silcd/protocol.c.
1197 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1198 commands that was missing it, and updated protocol specs and
1199 the server implementation. Protocol TODO #10. The affected
1200 file is silcd/command.c.
1202 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1203 generic reply to a generic request (REQUEST flag), and
1204 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1205 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1206 to define the payload for DATA flag. Added the flags to
1207 the implementation. Protocol TODO #9. Affected file is
1208 lib/silccore/silcchannel.h.
1210 Changed the client library to return the message length
1211 to application as well in the channel_message and private_message
1212 client operations. Affected files are
1213 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1214 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1215 and lib/silcclient/client_ops_example.c.
1217 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1218 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1219 the channel. Updated protocol specs and impelemented this
1220 to client and server. Protocol TODO #6. Affected files are
1221 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1222 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1224 Added new options m and M to CMODE command in Irssi SILC
1225 client to set these modes.
1227 * Deprecated all administrative commands from SILC protocol
1228 since they are highly implementation specific commands.
1229 Updated protocol specs. Moved the old commands in
1230 implementations to private range of command types. Affected
1231 files are silcd/command.c, lib/silcclient/command.c and
1232 lib/silcclient/command_reply.c. Protocol TODO #8.
1234 * Fixed a bug in server where sending unknown command crashes
1235 the server. Affected file silcd/command.c.
1237 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1239 * Added SILC_PROTOCOLVERSION macro to check protocol version
1240 of a socket connection. The affected file is
1241 lib/silcutil/silcsockconn.h.
1243 * Added better error logging in rekey protocol. Affected file
1246 * Do not check public key types in SKE during rekey. Affected
1247 file lib/silcske/payload.c.
1249 * Fixed the rekey protocol with PFS, which was totally broken.
1250 Affected file silcd/protocol.c.
1252 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * Some client implementations quit network by doing first LEAVE
1255 and then immediately SIGNOFF (like Bombyx). We now do check
1256 after a short time after LEAVE notify and check whether the
1257 client is still valid after LEAVE, and if not we remove it from
1258 cache. Affected file is lib/silcclient/client_notify.c.
1260 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1262 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1263 it's good not to have security holes here.
1265 * Fixed a negative refcount situtuation for the config context.
1266 Affected file is silcd/serverconfig.c.
1268 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1270 * ROBOdoc documented lib/silcutil/silcutil.h.
1272 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Optimized even more the SilcPacketContext structure. Now
1275 totally saved 16 bytes of memory per context after optimization.
1276 Affected files are lib/silccore/silcpacket.[ch].
1278 * Made strict checks for valid SILC IDs. Affected file is
1279 lib/silccore/silcid.c.
1281 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1283 * Changed the object argument for silc_cipher_register,
1284 silc_hash_register, silc_hmac_register and silc_pkcs_register
1285 to const. Affected files are lib/silccrypt/silccipher.[ch],
1286 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1288 * Changed the silc_get_username and silc_get_real_name to
1289 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1291 * Fixed the Irssi SILC Client to use the silc_get_username and
1292 silc_get_real_name insted of glib routines since the glib
1293 routines only corrupt stack. Fixes the Irssi SILC to work in
1294 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1296 * Fixed the Irssi to not use g_get_home_dir since it crashes
1297 or returns garbage on cygwin and corrupts stack. Added function
1298 get_home_dir to Irssi routines. Affected files are
1299 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1301 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1303 * Made some structure optimizations. SFTP memory FS MemFSEntry
1304 entry structure. Optimized SilcTask structure. Optimized
1305 SilcPacketContext structure.
1307 Affected files lib/silcsftp/sftp_fs_memory.c,
1308 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1310 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1312 * And yet again reverted back the config thing since Johnny
1313 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1316 * Fixed memory leaks from config object. Affected files are
1317 silcd/serverconfig.[ch].
1319 * Added support for adding new connections to the server in rehash.
1320 After rehash they take effect.
1322 Added support for changing the maximum allowed connections in
1323 rehash. The number can grow but going smaller is not supported.
1325 Added function silc_server_num_sockets_by_remote to the
1326 silcd/server_util.[ch].
1328 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1330 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1332 * Added preliminary checking during config parsing for a valid
1333 public/private key and removed further checks in the code.
1334 Affected files are silcd/serverconfig.[ch], server.c.
1336 * Moved functions silc_server_drop() and silc_server_daemonise()
1337 from server.c to silcd.c since they are stricly related to
1338 the application activity.
1340 * Reverted a small part of the automatic ref/unref since
1341 it caused a double unref in some situations. Affected
1342 files are silcd/silcd.[ch], server.c, serverconfig.c.
1344 * Added some .cvsignore files in the lib directory.
1346 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1348 * Fixed silc_net_gethostbyaddr to correctly resolve by
1349 address. Affected file lib/silcutil/silcnet.c.
1351 * Fixed the notify relaying to client. The HMAC to be used
1352 with relayed packets ws wrong and caused decryption failure
1353 at the client end. Affected file is silcd/packet_receive.c.
1355 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1357 * Created new branch silc_protocol_1_0_branch.
1359 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1361 * Changed the silc_server_config_* routines to be SilcServer
1362 independent. They are now officially application specific code
1363 and not part of generic server implementation. Affected files
1364 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1366 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1368 * Added automatic referencing of config context in the
1369 silc_server_config_alloc, and automatic unreferencing in the
1370 silc_server_config_destroy. Affected files are
1371 silcd/serverconfig.[ch], silcd/silcd.c.
1373 * Fixed the silc_log_quick handling in the logging routines.
1374 It didn't log quickly when it was TRUE. Affected file is
1375 lib/silcutil/silclog.c. Also the flush delay was set even
1376 if it was 0 in config file. Affected file is
1377 silcd/serverconfig.c.
1379 * Added support for changing key pair of the server in rehash.
1380 Affected file silcd/server.c.
1382 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1385 too early, before getting the channel entry. Affected file
1386 is silcd/packet_receive.c.
1388 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1390 * Added functions silc_server_config_[ref/unref], these are used
1391 to prevent that the config object is destroyed.
1393 No longer directly affect global variables silc_log_quick and
1394 silc_log_delay, they are first cached inside the config object
1395 and then applied with silc_server_config_setlogfiles().
1397 silc_server_config_set_defaults() is now internal to
1398 serverconfig.c, there are no reasons to show this internal stuff
1401 Affected files are silcd/serverconfig.[ch].
1403 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1404 fprintf's to stderr, since some code may be executed again after
1405 the server went into the background. Affected files are
1408 * Added rehash support. Added function silc_server_rehash() that
1409 will perform all the basic tasks of the rehashing procedure.
1411 * Added command line option `-x, --hexdump'. This will enable the
1412 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1413 The option `--hexdump' implies `--debug'.
1415 * Fixed a bad bug in the logging APIs (silcutil library) where
1416 the application would crash after calling silc_log_reset_all().
1418 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1420 * Fixed the KICKED notify handling in client library to
1421 correctly remove the channel and all entries from the
1422 channel when I was kicked. This bug crashed the client.
1424 Fixed yet another but in KICKED notify handling to remove
1425 the kicked client correctly from the channel.
1427 Affected file is lib/silcclient/client_notify.c.
1429 * Fixed a minor bug in looking up correct client entry
1430 in KICKED notify in server. Affected file is
1431 silcd/packet_receive.c.
1433 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1434 sources correctly to distribution. Fixes --with-gmp option.
1436 * Removed the manual rehashing from ID Cache, and changed it
1437 to use the SILC Hash Table's auto rehash feature. Affected
1438 file is lib/silccore/silcidcache.c.
1440 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1442 * Fixed a bug in the silc_client_nickname_format function that
1443 handles the multiple same nickname formatting. Two clients
1444 with same nickname caused problems after the first one left
1445 and rejoined. It didn't format the nickname correctly.
1446 Affected file is lib/silcclient/idlist.c.
1448 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1450 * Don't change the topic if olod topic is same as new one.
1451 Affected file is silcd/packet_receive.c.
1453 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1455 * Added cross-reference support to the SILC Documentation
1456 generator. All types across all HTML files are now cross-
1457 referenced. Affected files util/robodoc/generator.c and
1458 scripts/silcdoc/silcdoc.
1460 * Added file lib/silcutil/silctypes.h to include all the
1461 arithmetic type definitions and some macros. Removed
1462 includes/bitmove.h and moved macros to silctypes.h.
1464 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1466 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1475 allowed by the sender. Affected file silcd/packet_receive.c.
1477 * Added check for CUMODE_CHANGE notify type that mode change is
1478 allowed by the sender. Affected file silcd/packet_receive.c.
1479 Added the ID type as CUMODE_CHANGE notify type as argument
1480 to the `notify' client operation. Affected files are
1481 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1483 * Added function silc_client_add_server to the client library.
1484 Added support for resolving also channel and server info when
1485 received unknown entity in notify packet. Affected files are
1486 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1488 * Added function silc_command_get_status to return the command
1489 status from the command reply's argument payload. Affected files
1490 are lib/silccore/silccommand.[ch].
1492 * Added check for KICKED notify type that the kicking is
1493 allowed by the client. Affected file silcd/packet_receive.c.
1495 * Created function silc_get_input which can be used to get input
1496 (echo on or off) from user on command line. Affected files are
1497 lib/silcutil/silcutil.[ch].
1499 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1501 * Optimized silc_server_packet_relay_to_channel function.
1502 Added new function silc_channel_message_payload_encrypt which
1503 can be called directly if channel message payload needs to
1504 be encrypted and is already encoded (no need to call _encode
1505 function). Packet relaying is now done by router without any
1506 extra memory allocations. Affected files are
1507 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1508 silcd/packet_send.c.
1510 * Fixed the INVITE notify handling. It took wrong arguments
1511 as invite list and invite delete. Affected file is
1512 silcd/packet_receive.c.
1514 * Added check for TOPIC_SET notify type that the topic change is
1515 allowed by the client. Affected file silcd/packet_receive.c.

1528 by the client. Affected files are silcd/server_util.[ch],
1529 silcd/packet_receive.c and silcd/command.c.
1531 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1533 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1534 ID length. It ignored that ID can be IPv6 based as well.
1535 Affected file lib/silccore/silcpacket.h.
1537 * Fixed the silc_id_id2str and silc_id_str2id to take the
1538 IPv6 address offset's into consideration. Affecte file is
1539 lib/silccore/silcid.c.
1541 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1543 * Fixed the internal Unix scheduler functions to check for
1544 NULL context they may receive. The affected file is
1545 lib/silcutil/unix/silcunixschedule.c.
1547 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1549 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1550 can specify different directory with --home command line
1551 parameter. Affected files irssi/src/silc/core/client_ops.c,
1554 * SILC-specific commands aren't now executed if the active server
1555 isn't of SILC-type, so there won't be problems with having
1556 IRC and SILC protocol support in same client. Affected files
1557 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1560 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1562 * Improved the signal support in SILC Schedule. Added new
1563 function silc_schedule_signal_call which is used by application
1564 to mark a signal to be called. It is now safe to perform
1565 any kind of tasks in signal callbacks since it is guaranteed
1566 that the application specified signal callback is called
1567 after the signal is over. Affected files are
1568 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1570 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1572 * Added `name' field to SilcChannelPrivateKey to represent
1573 application given name for the key. Moved also the context from
1574 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1575 Added the `name' argument also to the function
1576 silc_client_add_channel_private_key.
1578 Added function silc_client_current_channel_private_key to set the
1579 current channel private key in use.
1581 Added "change" command to KEY command which can be used to change
1582 the current channel private key. Bound the command also to
1583 alt+K (Alt+Shift+k).
1585 Also affected files lib/silcclient/client_channel.c,
1586 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1588 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1590 * Added silc_rng_get_byte_fast function in to the
1591 lib/silccrypt/silcrng.[ch].
1593 * Changed the interface of silc_packet_assemble and the
1594 silc_packet_send_prepare. If silc_packet_assmble is now
1595 called the application does not call silc_packet_send_prepare
1596 because the library will call it automatically. These
1597 interfaces now also return a reference to the outgoing buffer
1598 which includes the assembled packet, which the application can
1599 use to encrypt the packet.
1601 Affected files are lib/silccore/silcpacket.[ch],
1602 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1603 silcd/packet_send.c, server_backup.c and packet_receive.c.
1605 * Fixed a packet sending bug on very high load, where outgoing
1606 packet queue wasn't handled correctly and packets got corrupted.
1607 Affected files are lib/silcutil/*/silc*sockconn.c,
1608 lib/silcclient/client.c and silcd/server.c.
1610 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1612 * Added macro SILC_PACKET_DATALEN which can be used during
1613 packet assembling to check whether the data to be added to
1614 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1615 len is truncated until it fits it.
1617 Added checks for maximum length of channel message payload and
1618 private message payload also.
1620 Added checks for maximum packet length in server and in
1623 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1624 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1625 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1626 lib/silcclient/client_prvmsg.c.
1628 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1630 * Added silc_server_packet_queue_purge call to the
1631 silc_server_disconnect_remote to assure that all data in the
1632 queue before disconnecting is sent to the network. Affected
1633 file silcd/server.c.
1635 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1637 * Added the deleting of server's own ID cache entry to the
1638 silc_server_free function. Free also everything else that
1639 has been allocated in silc_server_init. The affected file
1642 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1644 * Added functions silc_parse_version_string, silc_version_to_num,
1645 and silc_ske_parse_version to parse SILC protocol style version
1646 strings. Affected files lib/silcutil/silcutil.[ch] and
1647 lib/silcske/silcske.[ch].
1649 * Added new configuration params: version_protocol, version_software
1650 and version_software_vendor to specify what version the remote
1651 host must at least be to be able to connect to server. The vendor
1652 string can be regex matched too. Added new function
1653 silc_server_connection_allowed to check maximum number of allowed
1654 connections, and allowed versions for incoming connections.
1655 Affected files are silcd/server.c, server_util.[ch] and
1658 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1660 * Added preliminary support for signals in scheduler. The
1661 signals we care about are now blocked always when the scheduler
1662 is locked. This way we can synchronise the use of signal with
1663 scheduler. It is guaranteed that when signal occurs the scheduler
1664 is not locked, and thus new tasks can be safely added to the
1667 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1668 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1669 Added new platform specific routines
1670 silc_schedule_internal_signals_[un]block and
1671 silc_schedule_internal_signal_[un]register.
1673 Added new functions to SILC Schedule API:
1674 silc_schedule_signal_[un]register. Each signal that application
1675 is going to use should be registered to the scheduler.
1677 Affected files are lib/silcutil/silcschedule.[ch],
1678 lib/silcutil/*/silc*schedule.c.
1680 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1682 * Check for unauthenticated client and server in the
1683 silc_server_new_client and silc_server_new_server functions.
1684 Affected file silcd/packet_receive.c.
1686 * Added function silc_string_is_ascii to check whether given
1687 string is 7-bit ASCII string. Affected files are
1688 lib/silcutil/silcutil.[ch].
1690 * Added function silc_id_is_valid_server_id into the
1691 silcd/serverid.c and added checking for valid Server ID's in
1692 silc_server_new_server. The Server ID must always be based
1693 on the server's public IP address.
1695 * Added logging of DISCONNECT packet message in the server.
1696 Affected file silcd/server.c.
1698 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1700 * Changed all library interfaces that use Global RNG to also
1701 accept SilcRng as argument. Affected files are
1702 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1703 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1704 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1705 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1706 lib/silccrypt/rsa.c.
1708 * Added function silc_pkcs_generate_key to the
1709 lib/silccrypt/silcpkcs.[ch] for applications so that they
1710 don't need to do pkcs->pkcs->init calls anymore.
1712 * Remove SilcSocketConnection from the SFTP API since it really
1713 wasn't needed there. The application has the information
1714 saved in its contexts anyway and the SFTP layer doesn't need
1715 know about it. Affected files lib/silcsft/silcsftp.h and
1716 lib/silcsftp/sftp_[server/client].c.
1718 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1719 The SilcSimContext is not SilcSim.
1721 * Fixed possible buffer overflows in silc_id_render in the
1722 lib/silcutil/silcutil.c.
1724 * On EPOC the global crypto module lists are not used at all
1725 in the crypto library. Added support for using the constant
1726 algorithm list on EPOC. Affected files are
1727 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1730 * Fixed the handling of third parameter of KICKED notify, since
1731 it was mistakenly updated to SILC Protocol 1.0 even though it
1732 is to be included in 1.1. Since it is not in 1.0 it is not
1733 mandatory, and this fix now handles it only if it is provided,
1734 and it is not error if it is not provided. Affected file
1735 lib/silcclient/client_notify.c.
1737 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1739 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1740 client. Affected file irssi/src/silc/core/client_ops.c.
1742 * Merged with Irssi 0.8.4 from irssi.org CVS.
1744 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1746 * Check for valid socket connection in client entries before
1747 sending any messages. Fixes a crash, but doesn't fix some
1748 other underlaying bug that is lurking there. Affected
1749 file silcd/packet_send.c.
1751 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1753 * $usermode, $cumode and $cumode_space expandos shouldn't do
1754 anything with non-SILC server records. Affected file
1755 irssi/src/silc/core/silc-expandos.c
1757 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Fixed the silc_net_check_[host/local]_by_sock to support
1760 IPv6 bound sockets as well. Now they can return IPv6 addresses
1761 as well. Affected file lib/silcutil/silcnet.c.
1763 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1764 Affected lib/silcutil/unix/silcunixnet.c.
1766 * Fixed ID rendering (at least on some platforms, not NetBSD)
1767 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1769 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1771 * Added silc_hash_public_key and silc_hash_public_key_compare
1772 functions to be used with SilcHashTable. They can be used to
1773 hash public keys and compare public keys in hash table. Affected
1774 file lib/silcutil/silcutil.[ch].
1776 * Added support for specifying multiple public keys for Client
1777 connection section in server configuration file. This makes it
1778 possible to accept multiple public keys from same host, or to
1779 make a section that accepts any incoming host, and have the
1780 accepted public keys listed in the section.
1782 Added functions silc_sever_[find/get]_public_key, added the
1783 support for this actually to all connection sections but only
1784 the Client section is currently allowed to specify multiple
1787 Affected files are silcd/server.c, server_internal.h,
1788 command.c, protocol.c, server_util.[ch], packet_receive.c.
1790 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Merged Irssi 0.8.2 from irssi.org CVS.
1794 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1796 * If silc_debug is TRUE, also output standard logging messages
1797 to stderr with the debug output.
1799 Made silc_log_reset_all() flushing all channels before returning.
1800 Also fixed some documentation typos.
1802 Affected files are lib/silcutil/silclog.[ch].
1804 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1806 * Fixed the server to check correctly the amount of connections
1807 from single host, by checking also the type of the connection.
1808 Fixed also the comparison of number of connections and number
1809 of allowed connections. Affected files are silcd/server.c,
1812 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1814 * Fixed the USERS command reply to save the user's mode on the
1815 channel as well. Fixed JOIN command reply to check whether a
1816 client is on channel already and not join it twice. Affected
1817 file lib/silcclient/command_reply.c.
1819 * Added new file silc-expandos.c into irssi/silc/core/ to return
1820 various stuff for various signal for the statusbar etc. updating.
1821 Now Irssi SILC client prints channel user modes etc. on the
1824 * The user mode (like server/router operator changes) is now shown
1825 on the Irssi SILC client's statusbar. The affected files are
1826 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1828 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1830 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1831 to SILC_SCHEDULE_[UN]LOCK macros.
1833 * Added more error printing to logs in server code. Affected
1834 files silcd/server.c and silcd/protocol.c.
1836 * Fixed -S option parsing in Irssi SILC Client. Affected file
1837 irssi/src/silc/core/silc-core.c.
1839 * Added silc_buffer_alloc_size function. Affected file is
1840 lib/silcutil/silcbuffer.h.
1842 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1844 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1845 constants. Affected files in
1846 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1849 * Changed the internal SFTP Memory FS table to const. Affected
1850 file lib/silcsftp/sftp_fs_memory.c.
1852 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1854 * Fixed the buffer formatting and unformatting routines to
1855 check the size of 64 bits types with sizeof(). Affected
1856 file is lib/silcutil/silcbuffmt.c.
1858 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1860 * Removed 0.6.x backwards support.
1862 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1864 * Changed all integer type names:
1865 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1866 to avoid collisions with other libraries using same type names
1869 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1871 * Added `prefer_ipv6' argument to the functions
1872 silc_net_gethostbyname[_async]. If it is TRUE it will return
1873 IPv6 address over IPv4. If FALSE IPv4 address is returned
1874 even if IPv6 address was found. Affected files
1875 lib/silcutil/silcnet.[ch].
1877 * Added support silc_net_create_connection[_async] to fallback
1878 to IPv4 address if IPv6 address could not be used (like if
1879 it doesn't work on a specific system). Affected file in
1880 lib/silcutil/unix/silcunixnet.c.
1882 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1884 * Added silc_schedule_reinit function to do the enlarging
1885 of the max tasks handling capabilities of the scheduler.
1886 Affected files lib/silcutil/silcschedule.[ch].
1888 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1890 * Added automatic extern "C" { ... } for C++ compilers so the
1891 application does not need to define them. Affected file
1892 includes/silcincludes.h.
1894 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1895 old name went against naming convention. Applications now
1896 include "silcclient.h" instead of "clientlibincludes.h".
1897 Removed includes/clientlibincludes.h, it is redundant now.
1899 * Renamed includes/version.h to silcversion.h.
1901 * Added really preliminary support for OS/2 into the util
1902 library. Only thread & mutex API is implemented, others
1903 are still to be implemented. Created the lib/silcutil/os2/
1904 directory. Created also file includes/silcos2.h.
1906 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1908 * Added preliminary BeOS support into the util library.
1909 Created lib/silcutil/beos/, and implemented all the needed
1910 functions to support SILC on BeOS. Created also file
1911 includes/silcbeos.h.
1913 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1915 * Added proper initializations to silc's irssi code, so it's
1916 now possible to load it as module. Affected files
1917 irssi/src/silc/core/silc-core.c,
1918 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1920 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1922 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1925 * Fixed the silcdoc document generator to correct generate
1926 docs from all kinds of filenames. Affected files are
1927 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1929 * ROBOdoc documented lib/silcutil/silcmemory.h.
1930 Added also new function silc_memdup.
1932 * Removed lib/silcutil/silcbufutil.h and moved those routines
1933 to the lib/silcutil/silcbuffer.h.
1935 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1937 * Added `user_count' to the SilcChannelEntry which now tells the
1938 number of users on the channel. The user count is now saved
1939 in normal server of global channels as well. Affected files
1940 silcd/server.c, idlist.h, packet_receive.c and command.c.
1942 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1943 include file utility functions.
1945 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1946 instead of calling directly OS routines.
1948 * Fixed NICK change printing in Irssi SILC Client. Fixed
1949 KICKED notify printing in Irssi SILC Client. Affected file
1950 irssi/src/silc/core/client_ops.c.
1952 * Fixed a NICK change bug in client library, to not recreate the
1953 client_entry->channels hash table everytime nick is changed.
1954 Affected file lib/silcclient/client.c.
1956 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1958 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1959 the SKE interface a bit.
1961 * Fixed padding problem in PKCS#1. The padding was not actually
1962 random since the random number generator was used incorrectly.
1963 This security bug affects only when encrypting with PKCS#1, and
1964 it is not currently used at all in SILC. SILC only use signing
1965 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1967 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1969 * Rewrote the notify handling in Irssi SILC client to not call
1970 the events as signals. Fixes problems with Perl support.
1971 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1973 * Send the auto-nicking NICK command in client library with
1974 little timeout after connecting. The affected file is
1975 lib/silcclient/client.c.
1977 * Added following new config file settings:
1978 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1979 key_exchange_timeout, conn_auth_timeout, connections_max,
1982 Implemented all the new config settings handling in the server.
1984 Optimized the use of SKE Mutual flag usage. Use it only
1985 if connection authentication protocol is not based in public
1988 Renamed all SilcServerConfigSection* to SilcServerConfig*
1989 to have a bit shorter names.
1991 Affected files silcd/serverconfig.[ch], server.[ch], and
1994 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1996 * Cleaned up the listening sockets code, preparing for the rehash
1997 support. Affected file is silcd/server.c.
1999 * Fixed some output messages. Affected files are silcd/silcd.c,
2002 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Create lib/doc/silcrng_intro.html document as introduction
2005 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2007 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2009 * Fixes to the silcd config template. Affected file is
2010 doc/example_silcd.conf.in.
2012 * Removed type casts from silc_calloc(), conforming to the
2013 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2015 * Removed param_name member from client, server, and router
2016 section structs, now identifying the param directly.
2018 Added CONFIG_FREE_AUTH macro in config file parsing.
2020 Affected files are silcd/serverconfig.[ch].
2022 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2024 * Fixed command line parameter handling. All SILC initialization
2025 is now done in silc_core_init() which also fixes autoconnecting
2028 Affected files irssi/src/silc/core/silc-core.c,
2029 irssi/src/fe-text/silc.c.
2031 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2033 * Added new configuration options and blocks:
2034 keepalive_secs, reconnect_count, reconnect_interval,
2035 reconnect_interval_max, reconnect_keep_trying and
2036 require_reverser_lookup. Added ConnectionParam block, and
2037 implemented the connection parameters when connecting as
2038 initiator and when accepting connections as responder.
2040 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2041 whether given configuration value has been given already.
2043 Affected files silcd/serverconfig.[c], server.[c].
2045 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2046 algorithm parts and created new file silcalgs.conf, that
2047 is now included from the example_silcd.conf.in.
2049 * Optimized the silc_server_connect_to_router_second to take
2050 the connection configuration object from the SilcServerConnection
2051 object instead of finding it during the connecting phase.
2052 Added the configuration object to SilcServerConnection struct.
2053 Affected files silcd/server_internal.h, server.c.
2055 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2057 * Add the client on channel after it was resolved at the
2058 channel message receiving, and it was not already on the
2059 channel. Affected file lib/silcclient/client_channel.c.
2061 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2063 * Fixed the public key authentication to allocate always the
2064 destination signature buffer instead of using static buffer.
2065 Affected file silcd/protocol.c.
2067 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2069 * Unified the serverconfig.[ch]'s helper function interface.
2070 Affected file silcd/serverconfig.[ch].
2072 * Removed doc/example_silc.conf.in since it is redundant.
2073 The make install will now install irssi/silc.conf file.
2075 * Added new Passphrase and Publickey authentication methods to
2076 config file, allowing both public key and passphrase based
2077 authentication to be set at the same time.
2079 Added `prefer_passphrase_auth' setting in config file which
2080 can be used to set to prefer passwd auth if both passwd and
2081 public key is set. If not set, public key is preferred.
2082 This has effect only when being initiator (responder will try
2085 Added support for authentication with passphrase and public key
2086 at the same time. The passphrase is tried first always since
2087 it is faster to check.
2089 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2091 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2093 * Merged the new SILC Config library, with the server parsing
2094 support. Read the header file silcconfig.h or the toolkit
2095 documentation for the news. Affected files are
2096 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
2097 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
2098 silcd/protocol.c silcd/server.c silcd/server_backup.c
2099 silcd/serverconfig.[ch] silcd/silcd.c.
2101 * Fixed some silclog documentation. Affected file is
2102 lib/silcutil/silclog.h.
2104 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2106 * The silc_cipher_register, silc_hash_register and
2107 silc_hmac_register now checks if the object to be registered
2108 is registered already. Affected files are
2109 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2111 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2113 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

2117 * Allow zero length channel messages inside the Channel Message
2118 Payload. Affected file lib/silccore/silcchannel.c.
2120 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2121 as header filenames.
2123 * Removed lib/silcclient/README and created HTML file
2124 lib/silcclient/silcclient_using.html, which is now included
2125 as part of Toolkit documentation.
2127 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2129 * Fixed CUMODE_CHANGE notify handling to change the mode of
2130 correct client. Affected file lib/silcclient/client_notify.c.
2132 * Make silc_rng_alloc fail if it cannot allocate the sha1
2133 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2135 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2137 * Fixed the file transfer's key agreement payload to include
2138 zero port also if the hostname is NULL because it could not
2141 Call file transfer monitor callback now also if error occurs
2142 during key agreement protocol.
2144 Changed the silc_client_file_send interface to return the
2145 SilcClientFileError instead of session id. The session ID
2146 is returned into pointer provided as argument.
2148 Check that the file exists locally before sending the
2149 file transfer request at all.
2151 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2153 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2154 error than can occur while key agreement protocol. Affected
2155 file lib/silcclient/silcapi.h.
2157 * Fixed the event_mode CMODE handler to not crash when mode
2158 is changed and +k mode is set in the channel. Affected file
2159 irssi/src/silc/core/silc-channels.c.
2161 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2162 SILC_LOG_WARNING to give out Warning and not Error. Affected
2163 file lib/silcutil/silclog.c.
2165 * Fixed the channel message payload decryption in the function
2166 silc_channel_message_payload_decrypt to not modify the original
2167 buffer before it is verified that the message decrypted
2168 correctly. Otherwise, next time it is called with correct
2169 channel key it won't encrypt since the payload is corrupted.
2170 Affected file lib/silccore/silcchannel.c.
2172 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2174 * Do not constantly resize the window. A fix patch by cras.
2175 Affected file irssi/src/fe-text/screen.c.
2177 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2179 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2180 Affected file lib/silcutil/silcnet.c.
2182 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2184 * Fixed a bug in hash table internal routine for traversing
2185 the table with foreach callback. The current entry may
2186 become invalid in the callback but it was referenced after
2187 the callback returned.
2189 Do not allow auto rehashing of hash table during the
2190 silc_hash_table_foreach operation, for same reasons as it is
2191 not allowed for SilcHashTableList. Affected files are
2192 lib/silcutil/silchashtable.[ch].
2194 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2196 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2197 Win32 DLL. extern's in header files are now declared with
2200 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2202 * Fixed private message handling. It used some old code that
2203 caused the client to crash. Affecte file is
2204 lib/silcclient/client_prvmsg.c.
2206 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2208 * Added function silc_client_add_channel,
2209 silc_client_replace_channel_id, and removed functions
2210 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2211 from client library.
2213 * Added cross reference of the joined channels to the
2214 SilcClientEntry, and changed the SilcChannelEntry's
2215 users list to SilcHashTable. The affected files are
2216 lib/silcclient/idlist.[ch].
2218 * Fixed a bug in hash table tarversing. While the hash table
2219 is traversed with SilcHashTableList the table must not be
2220 rehashed. It is now guaranteed that auto rehashable tables
2221 are not rehashed while tarversing the list. Also defined that
2222 silc_hash_table_rehash must not be called while tarversing
2223 the table. Added function silc_hash_table_list_reset that must
2224 be called after the tarversing is over. The affected files are
2225 lib/silcutil/silchashtable.[ch].
2227 * Changed all hash table traversing to call the new
2228 silc_hash_table_list_reset in server and in client library.
2230 * Added function silc_client_on_channel to return the
2231 SilcChannelUser entry if the specified client entry is joined
2232 on the specified channel. This is exported to application as
2233 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2235 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2237 * Fixed founder regaining problem with JOIN command on normal
2238 server. The notify for mode change must be sent always and
2239 not only if !cmd->pending. Affected file silcd/command.c.
2241 * Fixed the WHOWAS command's reply sending to support the
2242 lists correctly. Affected file silcd/command.c.
2244 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2246 * When sending JOIN command to router for processing the
2247 sender's old command identifier was not saved back to the
2248 sender's command context, fixed now. The affected file is
2251 * Create the key in JOIN command of the router did not return
2252 the channel key, added check for this. Affected file is
2255 * Fixed a channel ID update bug in JOIN command reply. Do
2256 not directly upgrade the ID but call the function
2257 silc_idlist_replace_channel_id if the ID was changed.
2258 Affected file silcd/command_reply.c.
2260 * Fixed memory leaks from command calling if it would fail.
2261 Affected file silcd/command.c.
2263 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2265 * Applied patches from cras:
2267 Memory leak fixes around libaries, irssi window resize fix,
2268 new silclist.h and silcdlist.h, all extern inline changed to
2271 * Removed dotconf from lib/dotconf, not needed anymore.
2273 * Removed TRQ from lib/trq, not needed anymore.
2275 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2276 with server connections. Later this will be configurable
2277 in config file after new config file is done. Affected file
2280 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2282 * Fixed a crash in server related to channel announcements.
2283 Affected file silcd/server.c.
2285 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2287 * Fixed memory leaks in silc_server_create_new_channel*
2288 functions. Affected file silcd/server.c.
2290 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2291 which ID was changed. This way the router will send the
2292 user list for the channel again, and server won't be in
2293 desync in some rare circumstances. Affected file is
2294 silcd/packet_receive.c.
2296 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2298 * Check for NULL socket pointer in the function
2299 silc_server_packet_send_to_channel_real. Affected file
2300 silcd/packet_send.c.
2302 * Fixed the BAN notify handling to correctly remove ban
2303 list. Affected file silcd/packet_receive.c.
2305 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2307 * Fixed some header addition to Toolkit distribution in
2308 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2310 * Added lib/silcclient/client_ops_example.h as an template
2311 file for application programmers to quickly start using
2312 the SilcClientOperation functions in their application.
2313 Updated the lib/silcclient/README as well to tell about this
2314 nice file made available.
2316 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2318 * Call silc_server_remove_from_channels when removing client
2319 entry when NO_SUCH_CLIENT_ID was received. Affected file
2320 is silcd/command_reply.c.
2322 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2324 * Added server & router operator statistics updating. Affected
2325 file silcd/packet_receive.c and silcd/command.c.
2327 * Fixed the SERVER_SIGNOFF notify handling on normal server
2328 not to save the history information for clients. Same was
2329 fixed earlier in remove_clients_by_server function, but not
2330 here. Affected file silcd/packet_receive.c.
2332 * Raised the default connection-retry count from 4 to 7 in
2333 server. Affected file silcd/server.h.
2335 * Cancel any possible reconnect timeouts when we start the
2336 key exchange. Affected file silcd/server.c.
2338 * Do not reconnect on connection failure when SCONNECT was
2339 given. Affected files silcd/server.[ch].
2341 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2343 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2345 * Fixed the NICK command to always give the unformatted
2346 nickname to the one giving the NICK command. If unformatted
2347 nickname is cached already it will be formatted and the
2348 local entry will always get the unformatted nickname.
2349 Affected file lib/silcclient/idlist.c.
2351 * Fixed some double frees from client library commands.
2352 Affected file is lib/silcclient/command.c.
2354 * Fixed CUMODE command in server to assure that no one can
2355 change founder's mode than the founder itself, there was a
2356 little bug. Affected file silcd/command.c.
2358 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2360 * Removed the SilcClientCommandDestructor from the client
2361 libary, it is not needed anymore. Affected files are
2362 lib/silcclient/silcapi.h, command[_reply].[ch],
2363 client_notify, idlist.c.
2365 * Fixed GETKEY command to first resolve client, and then
2366 resolve the server only if the client was not found, instead
2367 of resolving both at the same time. Affected file is
2368 lib/silcclient/command.c.
2370 * Added silc_client_start_key_exchange_cb and lookup the
2371 remote hostname and IP address before starting the key
2372 exchange with server. The affected file is
2373 lib/silcclient/client.c.
2375 * The server's public key is now saved using the IP address
2376 of the server and not the servername for the filename.
2377 The hostname public key filename is checked as an fall back
2378 method if the IP address based filename is not found.
2380 Fixed the GETKEY command to save the fetched server key
2381 in correct filename.
2383 Print the remote server's hostname now when new key is
2384 received during connection process. Affected file is
2385 irssi/src/silc/core/client_ops.c.
2387 * Return always our own public key to the client if it asks
2388 for it with GETKEY command. Affected file silcd/command.c.
2390 * Removed the use_auto_addr variable from default config
2391 file since it was in wrong section. Affected file is
2394 * Fixed TOPIC_CHANGE notification to not route it when it
2395 was sent using silc_server_send_notify_to_channel function.
2396 Affected file silcd/command.c.
2398 * Fixed silc_server_send_notify_kicked to send the kicker's
2399 Client ID also, it was missing. Affected files are
2400 silcd/command.c, silcd/packet_send.[ch].
2402 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2404 * Do not save client history information in SERVER_SIGNOFF.
2405 Fixes the bug in normal server that it does not detect
2406 the client becoming valid after the server becomes back
2407 online. Affected file silcd/server_util.c.
2409 * Added `sock_error' field into the SilcSocketConnection
2410 context. When error occurs during socket operation (read
2411 or write) the error is saved. Added also new function
2412 silc_socket_get_error to return human readable socket error
2413 message. Affected files are lib/silcutil/silcsockconn.[ch],
2414 lib/silcutil/unix/silcunixsockconn.c, and
2415 lib/silcutil/win32/silcwin32sockconn.c.
2417 * The server now prints the socket error message in the
2418 signoff for client. Affected file silcd/server.c.
2420 * Fixed the `created' channel information sending from router
2421 to server in JOIN command. Checks now whether the channel
2422 really was created or not and set it according that.
2424 Fixed the JOIN command to use the client entry's current
2425 ID during the joining procedure instead of the one it sent
2426 in the command (it is checked though), since it can change
2427 between the packet processing and command processing, and
2428 would just case unnecessary pain in the client end. Affected
2429 file silcd/command.c.
2431 * Fixed a channel key payload sending to use correct channel
2432 ID when the server was forced to change the channel's ID by
2433 router. Router sent the key payload with the old Channel ID.
2434 Affected file silcd/packet_receive.c.
2436 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2438 * Call silc_server_save_channel_key only if the key payload
2439 was provided in the JOIN command's command reply. Affected
2440 file silcd/command_reply.c.
2442 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2444 * Fixed silc_mp_sizeinbase to return the value correctly with
2445 MPI. Affected file lib/silcmath/mp_mpi.c.
2447 * Fixed the stop_server signal to correctly stop the scheduler
2448 and gracefully stop the server when SIGTERM or SIGINT signals
2449 are received. Affected file silcd/silcd.c.
2451 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2453 * Simple handling of TERM and HUP signals. Also added some log
2454 flushing call around. Affected file is
2457 * Fixed small bugs in silclog.c. Now buffering output will take
2458 effect after 10 seconds since startup: This will ensure that
2459 no important startup messages are lost. Also output redirection
2460 will preserve original format ([Date] [Type] message).
2461 Affected file is lib/silcutil/silclog.c.
2463 * Added two options to the config file, in the logging section:
2464 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2465 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2467 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2469 * Do not print the warning about log files not being initialized
2470 more than once to avoid excess logging. Affected file is
2471 lib/silcutil/silclog.c.
2473 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2474 the SIM copying in make install in Makefile.am.pre.
2476 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2478 * Rewritten silclog APIs. Globally interesting changes follows:
2479 silc_log_set_files() changed to silc_log_set_file().
2480 silc_log_set_callbacks() changed to silc_log_set_callback().
2481 ROBOdoc documented silclog header file.
2482 SilcLogCb now returns bool to wether inihibit the default
2483 handler or not (to keep the old behaviour return always TRUE).
2484 The new APIs should also fix the problem of the
2485 silcd_error.log file that was written in the current directory.
2488 Log files streams will remain opened after silc_log_set_file()
2489 call, means less CPU usage notably on high traffic servers.
2490 File streams are now full buffered, and flushed to the disk
2491 every 5 minutes, lesses HD activity and CPU usage.
2492 Messages can be redirected, allowing admins to configure
2493 one single logfile for all server messages.
2494 the silc_log_quick global variable to activate fast-logging.
2495 Affected files lib/silcutil/silclog.[ch]
2497 * Changed some code to conform new silclog APIs. Affected
2498 files are doc/example_silcd.conf.in, silcd/server.c
2499 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2502 * Fixed a memory leak that could occur in some situations.
2503 Affected file silcd/serverconfig.c.
2505 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2507 * Added the silc_client_del_client to remove the client from
2508 all channels as well. Affected file lib/silcclient/idlist.c.
2510 * Fixed the client library to correctly remove the client
2511 from all channels when the client entry is being destroyed.
2512 Affected file lib/silcclient/client_notify.c, command.c.
2514 * Added auto-nicking support to the client library. If the
2515 applicatio now sets client->nickname it will be sent to the
2516 server after connecting by the library. This way for example
2517 SILCNICK (or IRCNICK) environment variables will have effect
2518 and always change the nickname automatically to whatever
2519 it is wanted. Affected file lib/silcclient/client.[ch].
2521 * Renamed silc_server_command_bad_chars to the
2522 silc_server_name_bad_chars and moved it to the
2523 silcd/server_util.[ch]. Added also new function
2524 silc_server_name_modify_bad to return nickname that
2525 includes bad characters as new nickname without those
2526 bad characters. This check and modify is now used in
2527 silc_server_new_client when the username is initially set
2528 as nickname, so it must be checked to be valid nickname.
2529 Affected file silcd/packet_receive.c.
2531 * The nickname length is now taken from the packet for real
2532 and not trusted to strlen() since it clearly can return
2533 wrong length for nickname including bad characters. This
2534 also applies to channel names. Affected file silcd/command.c.
2536 * Removed the lib/silcsilm/modules directory. Modules are now
2537 compiled into the lib/silcsim. Fixed the copying of the
2538 modules to follow symbolic links in Makefile.am.pre.
2540 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2542 * Fixed silc_string_regexify list creation. Fixes bugs with
2543 BAN and INVITE commands in server. The affected file is
2544 lib/silcutil/unix/silcunixutil.c.
2546 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Removed the command destructor entirely from the server's
2549 command and command reply routines. It is not needed, and
2550 its usage was buggy and caused crashes. Affected files are
2551 silcd/command[_reply].[ch].
2553 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2555 * Cancel protocol and NULL sock->protocol if timeout
2556 occurred during protocol. Affected file silcd/server.c.
2558 * Cancel protocol timeouts always before calling the final
2559 callback, to assure that after final callback is called
2560 no other state will be called for the protocol anymore.
2561 Affected file silcd/protocol.c.
2563 * Print error log if incoming connection configuration could
2564 not be found. Affected file silcd/server.c.
2566 * Fixed JOIN command to correctly save the founder mode
2567 to the client on normal SILC server, when the channel
2568 was created by the router. Affected file silcd/command.c.
2570 * Fixed LIST command (hopefully) to send correct reply
2571 packets. Affected file silcd/command.c.
2573 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * The silc_packet_receive_process now returns FALSE if the
2576 read data was invalid packet, and TRUE if it was ok.
2578 The server now checks that if unauthenticated connection
2579 sends data and its processing fails the server will close
2580 the connection since it could be a malicious flooder.
2582 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2584 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Make sure the warning about error opening a log file is
2587 printed only once and not everytime it fails (produces
2588 too much useless log). Affected file lib/silcutil/silclog.c.
2590 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2592 * Made the silc_server_daemonise() function more readable.
2593 Affected file silcd/server.c.
2595 * Pid file is now optional, the user may comment it out from
2596 the config file. Removed define SILC_SERVER_PID_FILE, we
2597 don't need a default any longer. Affected file
2598 configure.in.pre, lib/Makefile.am.pre.
2600 * Make some use of the pid file. The server now dies at startup
2601 if it detects a valid pid file on his path. The server would
2602 die anyway in this circumstance, because of the bind() failure.
2603 Affected file silcd/silcd.c.
2605 * No longer compiling lib/dotconf.
2607 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Fixed JOIN command parsing not to crash. Affected file
2610 lib/silcclient/command.c.
2612 * Fied the NICK_CHANGE notify to add the new client entry
2613 even it is resolved. This removes an <[unknown]> nick
2614 thingy bug in the client. Affected file is
2615 lib/silcclient/client_notify.c.
2617 * Do not try to allocate 0 bytes (efence does not like it)
2618 in lib/silccore/silccomand.c when encoding payload.
2620 * Do not take IRCNICK as nickname in Irssi SILC client since
2621 it is not possible to set nickname before hand connecting
2622 the server (TODO has an entry about adding auto-nicking
2625 * Changed the silc_server_command_pending to check whether
2626 there already exists an pending entry with the specified
2627 command, command identifier and pending callback. This is
2628 to fix IDENTIFY and WHOIS related crashes that may register
2629 multiple pending commands with same identifier. Affected
2630 file silcd/command.c.
2632 * Fixed the server to reconnect to the router even if it
2633 was already reconnecting and EOF was received. This to
2634 fix a possibility that the server wouldn't ever try to
2635 auto-reconnect to the router. Affected file silcd/server.c.
2637 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Fixed the server's password authentication to use the
2640 length of the locally saved password, and not the one
2641 sent in the packet. Affected file silcd/protocol.c.
2643 * Fixed same password authentication problem in the
2644 Authentication Payload handling routines in
2645 lib/silccore/silcauth.c.
2647 * Yet another password authentication problem fixed with
2648 channel password handling in silcd/command.c.
2650 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * If first character of string in silc_parse_userfqdn is '@'
2653 then do not parse it. Affected file is
2654 lib/silcutil/silcutil.c.
2656 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2658 * Fixed minor bug in IDENTIFY command reply sending, which
2659 caused various weird problems during JOIN when it was
2660 resolving names for users. Affected file silcd/command.c.
2662 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Fixed the IDENTIFY command reply sending to chech better valid
2665 clients. It was possible to send incomplete list of replies.
2666 Affected file silcd/command.c.
2668 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Added silc_client_command[s]_[un]register functions now to
2671 dynamically register the commands in client library. Removed
2672 the static table of commands. This allows the client library
2673 to call commands without causing the application to know about
2674 what commands library has called.
2676 Removed the INFO command reply kludge to detect when the command
2677 was called by library. Now library use its own command reply
2678 function for INFO command.
2680 Added function silc_client_command_call to call a command.
2681 Application can use it to call command, not access the structure
2684 Now all commands that are sent by the client library (not
2685 explicitly sent by application) use own command reply functions.
2687 Affected files around lib/silcclient/ and in
2688 irssi/src/silc/core/.
2690 * Fixed the WHOIS command reply sending to chech better valid
2691 clients. It was possible to send incomplete list of replies.
2693 Fixed the WHOIS and IDENTIFY to send the request to router
2694 if normal server did not do it and did not find any results.
2696 Affected file silcd/command.c.
2698 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Moved the internal data from SilcClient context into its
2701 own file, not accesible to application. Affected files
2702 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2703 and other files in client library.
2705 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Added doc/examples installation target in Makefile.am.pre.
2710 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2712 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2713 commands the found client entry will be removed from the
2714 cache, after notifying application about the error. Affected
2715 file lib/silcclient/command_reply.c.
2717 * Changed the /MSG to check for exact nickname user gave, and
2718 not let `nick' match `nick@host' if it is only one found. Now,
2719 user must type the exact nickname (like nick@host2) even if
2720 there are no more than one same nicks found. This is to avoid
2721 a possibility of sending nickname to wrong nickname since
2722 `nick' could match `nick@host'. Affected file is
2723 irssi/src/core/silc-servers.c.
2725 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2727 * Do not print "you are now server operator" or similar when
2728 giving /away command. Affected files are
2729 irssi/src/silc/core/client_ops.c, silc-servers.h.
2731 * Made the silc_server_command_pending_error_check to send
2732 the same command reply payload it received back to the
2733 original sender of the command. This way all arguments
2734 that was received by the server will be received by the
2735 client too. Affected file silcd/command.c.
2737 * Added the silc_idcache_add to return the created cache entry
2738 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2740 * Add global clients to expire if they are not on any channel.
2741 This is because normal server will never know if they signoff
2742 if they are not on any channel. The cache expiry will take
2743 case of these entries. This is done by normal servers only.
2744 The affected files are silcd/command_reply.c,
2745 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2747 * If server receives invalid ID notification for WHOIS or
2748 IDENTIFY and the ID exists in the lists, it is removed.
2749 Affected file silcd/command_reply.c.
2751 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2752 in client then client entry that it matches is searched and
2753 the nickname is printed on the screen for user. Affected
2754 file irssi/src/silc/core/client_ops.c.
2756 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Use cache entry expire time in the LIST command reply to
2759 purge old entries from the cache after the LIST command
2760 reply has been received. This way we don't have non-existent
2761 entries in the cache for too long. Affected file is
2762 silcd/command_reply.c.
2764 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * If we are normal server, and we've not resolved client info
2767 in WHOIS or IDENTIFY from router, and it is global client,
2768 we'll check whether it is on some channel. If it is not
2769 then we cannot be sure about its validity and will resolve it
2770 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2771 file silcd/command.c.
2773 * Search channel by name (if possible) rather than by ID
2774 in IDENTIFY command's command reply. Affected file is
2775 silcd/command_reply.c.
2777 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2780 Updated specs and implemented it. Affected file silcd/command.c,
2781 silcd/packet_send.c and silcd/packet_receive.c.
2783 * Implemented the <founder auth> payload handling in the JOIN
2784 command. If provided all conditions for channel joining
2785 except requirement to provide correct passphrase can be
2786 overrided by the channel founder. Updated the protocol specs.
2787 Affected file silcd/command.c.
2789 Added support for founder auth in JOIN command in client
2790 library. Fixed the parsing of the JOIN command now to support
2791 all options as they should be. The affected file is
2792 lib/silcclient/command.c.
2794 * Optimized the WHOIS and IDENTIFY commands to send the request
2795 to router only if it includes nicknames or other names. If
2796 they include only IDs then check the local cache first before
2797 routing. Affected file is silcd/command.c.
2799 * Added channels topic announcements. Affected file is
2800 silcd/packet_receive.c and silcd/server.c.
2802 * Fixed the silc_server_send_notify_topic_set to really destine
2803 the packet to channel. Affected file silcd/packet_send.c.
2805 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2806 library. Affected file lib/silcclient/client_notify.c.
2808 * Added UMODE announcements. Affected file silcd/server.c.
2810 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Memory leak fixes in:
2814 lib/silcutil/silcsockconn.c
2815 lib/silcske/silcske.c
2816 lib/silcske/groups.c
2818 lib/silccrypt/silcpkcs.c
2819 lib/silccore/silccommand.c
2820 lib/silccore/silcidcache.c
2825 * ROBOdoc documented the lib/silcske/groups.h file and a
2826 bit changed the interface for better.
2828 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2830 * Update the client entry context in the ID cache after
2831 nick change. Affected file lib/silcclient/command.c.
2832 Fixes the CUMODE command when regaining founder privileges,
2833 and a little WHOIS problem.
2835 * Fixed silc_net_gethostbyname to correctly call the
2836 inet_ntop. Affected file lib/silcutil/silcnet.c.
2838 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2840 * Added IPv6 support checking to the configure.in.pre, added
2841 also --enable-ipv6 option to override the check. Affected
2842 file configure.in.pre.
2844 * The silc_thread_create now calls the start function
2845 directly if threads support is not compiled in. Removes
2846 ugly #ifdef's from generic code. Affected files are
2847 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2849 * Added silc_net_gethostby[name/addr]_async to asynchronously
2850 resolve. Affected files are lib/silcutil/silcnet.[ch].
2852 * Added support for rendering IPv6 based server, client and
2853 channel IDs. Affected file lib/silcutil/silcutil.c.
2855 * Added support for creating IPv6 based server IDs. Affected
2856 file is silcd/serverid.c.
2858 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2860 * Added silc_net_gethostby[addr/name] into the
2861 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2862 routines. Added silc_net_is_ip[4/6]. Affected file is
2863 lib/silcutil/unix/silcunixnet.c. All routines that take
2864 address as argument now supports both IPv4 and IPv6 addresses.
2866 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2868 * Fixed LIST command reply sending in server. Affected file
2871 * Server now sends the kicker's client ID in the KICK notify
2872 to the kicked client. Affected file silcd/command.c.
2874 * The client library now parses the kickers client ID and
2875 UI displays it. Affected files lib/silcclient/client_notify.c
2876 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2878 * Made all payload parsing function prototypes consistent.
2879 They all take now const unsigned char * and uint32 pair as
2880 the payload data instead of SilcBuffer. Changes all around
2881 the source tree. Other unsigned char* -> const unsigned char*
2882 changes around the tree as well.
2884 * Optimized SFTP client and server packet sending not to
2885 allocate new buffer for each packet but to recycle the
2886 first allocated buffer. Affected files are
2887 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2889 * Optimized the SFTP client to use SilcList instead of
2890 SilcDList for requests, because it is faster. Affected file
2891 is lib/silcsftp/sftp_client.c.
2893 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2894 into lib/silccore/silcid.[ch].
2896 Renamed silcpayload.[ch] into silcargument.[ch].
2898 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * If client entry is deleted with active key agreement
2901 session, abort the session.
2903 The silc_client_abort_key_agreement now calls the completion
2904 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2906 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2909 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Don't use __restrict in older GCC's. Affected file is
2912 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2914 * silc_net_localhost now attempts to reverse lookup the
2915 IP/hostname. Affected file lib/silcutil/silcnet.c.
2917 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2918 command. It can be used to gain founder privileges at
2919 the same time when joining the channel.
2921 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2922 kicker's client ID as well. Updated protocol specs.
2924 Defined that the server must send SILC_COMMAND_IDENTIFY
2925 command reply with error status to client who sent
2926 private message with invalid client ID.
2928 Updated the protocol specification.
2930 * Added silc_server_send_command_reply to send any
2931 command reply. Affected file silcd/packet_send.[ch].
2933 * Added silc_id_payload_encode_data to encode ID payload
2934 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2936 * The server now send IDENTIFY command reply with error
2937 status if client ID in private message is invalid. Affected
2938 file silcd/packet_receive.c.
2940 * Save the server key file with server's IP address in
2941 the filename instead of hostname. The affected file is
2942 irssi/src/silc/core/client_ops.c.
2944 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2949 * Added libtool support for compiling shared objects in
2950 lib/silcsim. Affected file configure.in.pre and
2951 lib/silcsim/Makefile.am. Original patch by cras.
2953 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Pid file configuration, and server's config file fixes
2956 patch by toma. Updated CREDITS file.
2958 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Fixed silc_client_channel_message to not try to decrypt
2961 the message twice if it resolved the destination client
2962 information. This could cause of dropping one channel
2963 message. Affected file lib/silcclient/client_channel.c.
2965 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2968 lib/silcclient/client.c. This function is used when the SILC
2969 Client is run under some other scheduler, or event loop or
2970 main loop. On GUI applications, for example this may be
2971 desired to used to run the client under the GUI application's
2972 main loop. Typically the GUI application would register an
2973 idle task that calls this function multiple times in a second
2974 to quickly process the SILC specific data.
2976 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2978 * Fixed silc_server_drop() for dropping the supplementary
2979 groups as well, this could cause a security hole on some
2982 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2987 * Write PID file after dropping privileges. Added -F option
2988 to run server on foreground. A patch by debolaz.
2989 Affected files silcd/server.c, silcd/silcd.c.
2991 * Fixed MOTD to return the MOTD file server name. Affected
2992 file silcd/command.c.
2994 * Added INFO command reply handling to the Irssi SILC Client.
2995 Affected file irssi/src/silc/core/client_ops.c.
2997 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Fixed the silc_idcache_list_* routines to really support
3000 the dynamic list. Fixes a crash. Affected file is
3001 lib/silccore/silcidcache.c.
3003 * Fixed the LIST command reply to really call LIST command's
3004 pending callbacks. Affected file silcd/command_reply.c.
3006 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Update conn->local_entry->nickname after giving NICK
3009 command. Affected file lib/silcclient/command.c.
3011 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3013 * Added the [pid] option to the silcd configuration file
3015 Affected files: serverconfig.[ch] and silcd.c
3017 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Save fingerprint in WHOIS command reply in server.
3020 Affected file silcd/command_reply.c.
3022 * Fixed NICK commands pending callback registration.
3023 Affected file lib/silcclient/command.c.
3025 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Use ++server->cmd_ident when sending commands in server,
3028 instead of random number. Affected file silcd/command.c.
3030 * Fixed GETKEY command reply to call actually GETKEY pending
3031 command callbacks. Affected file silcd/command_reply.c.
3033 * A bit stricter check for nicknames. Check for same nickname
3034 in NICK command also. Affected file silcd/command.c.
3036 * Do not call INFO command everytime client ID changes, only
3037 during first connecting. Affected file lib/silcclient/client.c.
3039 * Set the new nickname only after successful command reply for
3040 NICK command is returned by server. Affected file
3041 lib/silcclient/command.c.
3043 * Remove nicknames from nicklist during server_signoff notify.
3044 Should fix /NAMES bit more. The affected file is
3045 irssi/src/silc/core/silc-channels.c.
3047 * Added `fingerprint' field to the SilcIDListData in the
3048 silcd/idlist.h to hold the fingerprint of the client's
3051 Send the fingerprint of the client's public key in WHOIS
3054 Affected files silcd/command.c, and silcd/idlist.[ch].
3056 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3057 create fingerprint from given data.
3059 * Show the fingerprint of the client's public key in WHOIS.
3060 Affected files irssi/src/module-formats.[ch] and
3061 irssi/src/silc/core/client_ops.c.
3063 * Format the multiple same nicknames also during JOIN and
3064 NICK_CHANGE notifys. Affected file is
3065 lib/silcclient/client_notify.c.
3067 * Do not print error on screen for invalid private message
3068 payload since it can come if someone is sending private
3069 messages with wrong key. Affected file
3070 lib/silccore/silcprivate.c.
3072 * Fixed multiple concurrent /PING crash. Affected file
3073 lib/silcclient/command.c.
3075 * Changed the wrong ID encoding. All IP addresses must be
3076 in MSB first order in encoded format. They were encoded
3077 wrong and was in LSB format. Affected files are
3078 silcd/serverid.c, lib/silcutil/silcutil.c.
3080 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3082 * Call the `connect' client operation through the scheduler
3083 in case of error. Affected file lib/silcclient/client.c.
3085 * Call the `failure' client operation even if the error
3086 occurred locally during a protocol. Affected file is
3087 lib/silcclient/protocol.c.
3089 * Added support of sending LIST command to router from normal
3090 server. This way normal server can get list of all channels
3091 in the network too. Fixed the channel list sending in the
3092 server too. Affected files are silcd/command.c, and
3093 silcd/command_reply.[ch].
3095 * Added silc_server_update_channels_by_server and
3096 silc_server_remove_channels_by_server. They are used during
3097 disconnection of primary router and in backup router protocol.
3098 Affected file silcd/server_util.[ch], silcd/server.c and
3099 silcd/server_backup.c.
3101 * Fixed channel adding to global list in IDENTIFY command
3102 reply in server. Affected file silcd/command_reply.c.
3104 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * If the incoming packet type is REKEY or REKEY_DONE process
3107 that packet always synchronously. Fixes yet another MAC
3108 failed error on slow (dialup) connections. Affected file
3109 lib/silcclient/client.c and silcd/server.c.
3111 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Call check_version SKE callback for initiator too. Affected
3114 file lib/silcske/silcske.c.
3116 * Implemented fix for security hole found in the SKE that was
3117 fixed in the specification few days back; the initiator's
3118 public key is now added to the HASH value computation.
3119 Added backwards support for the old way of doing it too, for
3120 old clients and old servers. Affected file is
3121 lib/silcske/silcske.c.
3123 * Enabled mutual authentication by default in SKE. If initiator
3124 is not providing mutual authentication the responder will
3125 force it. This will provide the proof of posession of the
3126 private key for responder. The affected files are
3127 lib/silcclient/protocol.c and silcd/protocol.c.
3129 * Do not cache anymore the server's public key during SKE.
3130 We do mutual authentication so the proof of posession of
3131 private key is done, and if the server is authenticated in
3132 conn auth protocol with public key we must have the public
3133 key already. Affected file silcd/protocol.c.
3135 * Added new global debug variable: silc_debug_hexdump. If
3136 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3137 file lib/silcutil/silclog.[ch].
3139 * Fixed compilation warning due to char * -> const char *.
3140 Affected files lib/silcutil/silcnet.h, and
3141 lib/silccore/silcauth.[ch].
3143 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Fixed CMODE command when new channel key was created. If
3146 the creation failed the old key was removed. Next time giving
3147 same command would crash the server since the old key was
3148 freed already. Affected file silcd/command.c.
3150 * Fixed the silc_server_announce_get_channels to not crash
3151 on reconnect. Affected file silcd/server.c.
3153 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Added silc_log_set_debug_string function to set a regex
3156 string to match for debug output. Only the function names,
3157 or filenames matching the given debug string is actually
3158 printed. This way it is possible to filter out those debug
3159 strings that user is not interested in.
3161 Fixed a bug in silc_string_regexify.
3163 Affected files lib/silcutil/silclog.[ch], and
3164 lib/silcutil/unix/silcunixutil.c.
3166 * Changed the -d options in both server and Irssi SILC client
3167 to take the debug string as argument. Affected files
3168 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3170 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3172 * Added silc_hash_babbleprint to create a Bubble Babble
3173 Encoded fingerprint. The encoding is developed by Antti
3174 Huima (draft-huima-babble-01.txt), and it creates human
3175 readable strings out of binary data. Affected file
3176 lib/silccrypt/silchash.[ch].
3178 * Print the babble print now in addition of fingerprint as well
3179 in Irssi SILC client. Affected files are
3180 irssi/src/fe-common/silc/module-formats.[ch],
3181 irssi/src/fe-common/silc/core/client_ops.c.
3183 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Fixed a security problem found in SKE. The initiator's
3186 public key too is now added to the HASH hash value creation
3187 which is signed by the responder to create the SIGN value.
3188 This will prevent anyone in the middle to lie to the responder
3189 about the initiator's public key. If this is done now, the
3190 man in the middle will get caught. Updated the protocol
3193 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3195 * Better installation directory handling. Configure module
3196 paths and other paths automatically to example_silc* files
3197 in doc/. A patch by toma.
3199 * Fixed compiler warning from MPI library, and from SILC RNG.
3202 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3203 It can be configured with ./configure. A patch by toma.
3205 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Find correct make to use in prepare-clean. A patch by
3208 toma. Affected file prepare-clean.
3210 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3212 * Added irssi variables use_auto_addr, auto_bind_ip,
3213 auto_bind_port and auto_public_ip.
3215 * Changed the interface for silc_client_send_key_agreement
3216 in lib/silcclient/silcapi.h
3220 irssi/src/silc/core/silc-core.c
3222 lib/silcclient/silcapi.h
3223 irssi/src/silc/core/silc-channels.c
3224 lib/silcclient/client_keyagr.c
3227 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Added silc_pkcs_public_key_compare to compare two
3230 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3232 * Check that the client who set the founder mode on the
3233 channel is the same client that is giving the founder
3234 mode to itself. It is done by comparing the saved public
3235 key (it is saved even in the authentication is passphrase).
3236 Affected file silcd/command.c.
3238 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3240 * Do not process packet for disconnected socket connection.
3241 Affected file lib/silccore/silcpacket.c.
3243 * Process the DISCONNECT packet through scheduler in the
3244 client library. Affected file lib/silcclient/client.c.
3246 * Fixed the silc_client_packet_parse to not to increase
3247 the packet sequence number if the conn->sock and the
3248 current socket connection is not same. This can happen
3249 for example during key agreement when the conn includes
3250 multiple socket connections (listeners). Affected file
3251 lib/silcclient/client.c.
3253 * The sender of the file transfer request now provides also
3254 the pointer (listener) for the key exchange protocol. If
3255 the listener cannot be created then it sends empty key
3256 agreement and lets the receiver provide the listener.
3258 Added `local_ip' and `local_port' arguments to the
3259 silc_client_file_send. If they are provided they are used,
3260 if not then it will attempt to find local IP address, if
3261 not found or bind fails then the remote client will provide
3264 Affected files are lib/silcclient/client_ftp.c and
3265 lib/silcclient/silcapi.h.
3267 * Extended the FILE SEND command to support defining the
3268 local IP and port for key exchange listener. They are
3269 optional. Affected file irssi/src/silc/core/silc-servers.c.
3271 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Defined to WHOIS command reply the sending of fingerprint
3274 of the client's public key (if the proof of posession of the
3275 corresponding private key is verified by the server).
3276 Updated to the protocol specification.
3278 * Added support of receiving the client's public key's
3279 fingerprint in command reply in client library. Affected
3280 file is lib/silcclient/command_reply.c, and
3281 lib/silcclient/idlist.[ch].
3283 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3285 * Do not send over 128 chars long nickname to the server
3286 in NICK command. Affected file lib/silcclient/command.c.
3288 * Do not send over 256 chars long channel names to the server
3289 in JOIN command. Affected file lib/silcclient/command.c.
3291 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Assure that silc_server_close_connection cannot be called
3294 twice for same socket context. Affected file is
3297 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Send error message to application if opening file for
3300 writing during file transfer fails. Affected file is
3301 lib/silcclient/client_ftp.c.
3303 Remove all file transfer sessions for a client that we're
3304 removing from ID cache.
3306 Affected file is lib/silcclient/client_ftp.c.
3308 * Fixed silc_net_addr2bin to return correct address. Affected
3309 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3311 * Fixed file transfer session removing on signoff notify.
3312 Affected file irssi/src/silc/core/silc-servers.c.
3314 * Added the SilcClientFileError to be returned in the monitor
3315 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3316 Affected file lib/silcclient/silcapi.h.
3318 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Fixed a crash in silc_client_ftp_free_sessions and
3321 silc_client_ftp_session_free_client. Affected file
3322 lib/silcclient/client_ftp.c.

3335 * Fixed a crash in client resolving in client_prvmsg.c in
3336 client library. Affected file lib/silcclient/client_prvmsg.c.
3338 * Do not actually remove the client directly from ID cache
3339 during SERVER_SIGNOFF, but invalidate it. This way we
3340 preserve the WHOWAS info for the client. Affected file
3341 silcd/server_util.c.
3343 * Fixed SERVER_SIGNOFF notify handling in the server. The
3344 server is now able to process incoming SERVER_SIGNOFF notify
3345 for a server that it doesn't even know about. It will remove
3346 the clients provided in the notify. Affected file
3347 silcd/packet_receive.c.
3349 * Check for partial packet in data queue after every packet that
3350 was found from the queue. Return and wait for more data if
3351 there is partial data in queue. Affected file is
3352 lib/silccore/silcpacket.c.
3354 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3356 * Added SilcClietFileError enum to indicate error in
3357 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3358 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3359 Affected files lib/silcclient/silcapi.h and
3360 lib/silcclient/client_ftp.c.
3362 * Check that newsize in silc_buffer_realloc is larger than
3363 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3365 * Added better monitor of file transfers. It now monitors
3366 key agreement protocol during the file transfer too. Added
3367 error reporting too. Affected files
3368 irssi/src/silc/core/silc-servers.c,
3369 irssi/src/fe-common/silc/module-formats.[ch].
3371 * Wrote a help file for FILE command.
3373 * Added silc_rng_global_get_byte_fast to get not-so-secure
3374 random data as fast as possible. Random data is read from
3375 /dev/urandom if available and from the SILC RNG if not
3376 available. It is used in padding generation. Affected file
3377 lib/silccrypt/silcrng.[ch].
3379 * All packets in client library are now processed synchronously.
3380 Optimized packet processing a lot. Affected file
3381 lib/silcclient/client.c.
3383 * All server connection packets are processing synchronously
3384 now in server, to optimize packet processing. Affected file
3387 * Include files are installed now only in Toolkit distribution
3388 if make install is given. Affected files: all Makefile.am's.
3390 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3392 * Assure that silc_client_notify_by_server_resolve does not
3393 resolve the client information multiple times. If it cannot
3394 be found by the first it cannot be found at all. Affected
3395 file lib/silcclient/client_notify.c.
3397 * Fixed WHOWAS command reply calling. Affected file
3398 lib/silcclient/command_reply.c.
3400 * Removed all references to silc_idlist_get_client from the
3401 Irssi SILC client since that call is internal call used by
3402 the library. The Irssi SILC client will use now client
3403 retrieval functions found in silcapi.h.
3405 * Fixed a bug in resolving nickname info before sending
3406 private message. It used freed memory. Affected file
3407 irssi/src/silc/core/silc-servers.c.
3409 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Assure my_channels statistics cannot go negative in server.
3412 Affected files silcd/server.c, silcd/server_util.c.
3414 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3418 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

3428 * Added silc_net_localip to return local host's IP address.
3429 Affected file lib/silcutil/silcnet.[ch].
3431 * If key exchange or rekey protocol is active for a connection
3432 parse all packets syncronously since there might be packets
3433 in packet queue that we are not able to process without first
3434 processing packets before them. Affected file silcd/server,
3435 lib/silcclient/client.c.
3437 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3438 whether library should continue processing the packet.
3439 Affected file lib/silccore/silcpacket.h.
3441 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3442 SilcSFTPMonitorData to SFTP server to monitor various
3443 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

3450 Added preliminary support for simple client to client one-file
3451 transmission. Affected file lib/silcclient/client_ftp.c,
3452 lib/silccilent/client.[ch].
3454 * Added new local command FILE to the Irssi SILC Client.
3455 It is used to perform the file transfer. It has subcommands
3456 SEND, RECEIVE, SHOW and CLOSE. Affected files
3457 irssi/src/silc/core/client_ops.c,
3458 irssi/src/silc/core/silc-server.[ch].
3460 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3470 lib/silcutil/silcutil.[ch].
3472 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Resolve the client info when received private message or
3475 channel message for a client which nickname we don't know.
3476 Affected files lib/silcclient/client_prvmsg.c and
3477 lib/silcclient/client_channel.c.

3480 file irssi/src/silc/core/silc-channels.c.
3482 * Added SilcClientStatus field to the SilcClientEntry in the
3483 lib/silcclient/idlist.h.
3485 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3486 is incomplete and is being resolved, it won't be resolved
3489 Make sure also that USERS command reply does not resolve
3490 twice information. Affected file is
3491 lib/silcclient/command_reply.c.
3493 Make sure that silc_client_get_clients_by_list does not
3494 resolve twice same information.
3496 * Check for valid client->id in the silc_server_free_client_data.
3497 Affected file silcd/server.c.
3499 * Fixed /GETKEY nick@server not to crash if the server entry
3500 is not found. Affected file lib/silcclient/command.c.
3502 * Fixed the silc_server_check_cmode_rights to check the
3503 requested modes correctly. Affected file silcd/command.c.
3505 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Better checks for non-printable chars in nick added.
3508 Affected file silcd/command.c.
3510 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Call the silc_server_udpate_servers_by_server in the
3513 primary router that comes back online in the backup resuming
3514 protocol. Otherwise it routes packets wrong. Affected file
3515 silcd/server_util.[ch], silcd/server_backup.c.
3517 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3519 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3520 lib/silcutil/silcbuffmt.[ch].
3522 * Redefined the SILC packet header to include the padding
3523 length. Affected file lib/silccore/silcpacket.[ch].
3525 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3526 length for maximum padding up to 128 bytes). Affected
3527 file lib/silccore/silcpacket.h.
3529 * Removed all backwards support for old 0.5.x MAC thingies.
3530 The SILC packet header change makes it impossible to be
3531 backwards compatible.
3533 * Send the ENDING packet with timeout in the backup resuming
3534 protocol. This is to assure that all routers has connected
3535 to the primary router. Affected file silcd/server_backup.c.
3537 * Changed the RNG to take the first IV from random data. It
3538 used to take it from zero actually. Changed the RNG also
3539 to use /dev/urandom during session. /dev/random is used
3540 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3542 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * Changed the SILC packet header to have the first two bytes
3545 (the packet length) encrypted. Affected files aroung the
3546 code tree, lib/silccore/silcpacket.[ch]. Removed the
3547 SilcPacketCheckDecrypt callback. It is not needed anymore
3548 since the silc_packet_receive_process will determine now
3549 whether the packet is normal or special.
3551 * Implemented the unidirectional MAC keys. Affected files
3552 lib/silcske/silcske.c, silcd/protocol.c and
3553 lib/silcclient/protocol.c.
3555 * Implemented the packet sequence number to the MAC computation.

3560 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Allow backup router to announce servers. All servers
3563 announced by backup router are added to the global list
3564 automatically. Update hte server's socket to our primary
3565 router also when backup router announces a server.
3566 Affected file silcd/packet_receive.c.
3568 * Do not update the client->router in the function
3569 silc_server_udpate_clients_by_server if the client is on
3570 global list. We might fail to find any specific server
3571 for locally connected clients and local cell clients. They
3572 should still use the `from' and not `to' as client->router.
3573 This fixes backup router resuming protocol. Affected file
3574 silcd/server_util.c.
3576 * Decrease channel statistics count only if the channel
3577 deletion worked. Affected files are silcd/server.c and
3578 silcd/server_util.c.
3580 * Added silc_server_update_servers_by_server to update origin
3581 of all server entries. Used during backup router protocol.
3582 Affected files silcd/server_util.[ch], silcd/server.c. and
3583 silcd/backup_router.c.
3585 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3586 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3587 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3588 lib/silccrypt/silchmac.c.
3590 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3592 * Assure that router cannot reroute the same channel message
3593 to the sender. Affected file silcd/packet_receive.c.
3595 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Made better checks that the channel message is not sent
3598 to the router it came from. Affected file is
3599 silcd/packet_send.c. Fixed memory leak too.
3601 * Announce informations for incoming router connection, but
3602 only after checking if it is replaced by backup router.
3603 Affected file silcd/packet_receive.c.
3605 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Fixed the backup resuming protocol to work in multiple
3608 router environment. Affected file silcd/server_backup.c.
3610 * Route packet only to one router in the function
3611 silc_server_packet_send_to_channel. Affected file is
3612 silcd/packet_send.c.
3614 * Fixed silc_server_send_notify_dest to set the broadcast
3615 flag. Fixed the silc_server_send_notify_topic to actually
3616 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3617 Affected file silcd/packet_send.c.
3619 * Changed the SFTP Filesystem interface. Changed the
3620 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3621 the filesystem operation function. The SilcSFTPFilesystem
3622 is now a context that is allocated by all filesystem allocation
3623 functions and it already includes the operations structure
3624 and filesystem specific context. It is given as argument
3625 now to the silc_sftp_server_start. This made the interface
3626 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3627 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3629 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * Changed the backup router adding and getting interfaces
3632 in the server. The router that will be replaced by the
3633 specified backup router is now sent as argument. Affected
3634 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3637 * Added silc_net_addr2bin_ne to return the binary form of
3638 the IP address in network byte order. Affected files
3639 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3641 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3643 * Check for existing server ID in silc_server_new_server
3644 and in silc_server_connect_to_router_final and remove the
3645 old entry if it exists. Affected file silcd/packet_receive.c,
3648 * Send the channel message always to only one router, either
3649 in upstream or downstream. Affected file is
3650 silcd/packet_send.c.
3652 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Wrote the definition of the backup resuming protocol to the
3655 protocol specification.
3657 * Removed one redundant channel key generation from normal
3658 server during joining procedure. Removed one redundant
3659 channel key sending from server to router during joining
3660 procedure. Affected file silcd/command.c.
3662 * Made minor bugfixes to the backup router resuming protocol.
3663 Affected file silcd/server_backup.c, server.c.
3665 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Added --disable-asm configuration option. Affected files
3668 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3671 * Implemented the backup resuming protocol that is used to
3672 resume the primary router position in the cell after the
3673 primary router comes back online. Affected files
3674 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3675 and silcd/server_util.[ch].
3677 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3679 * Sleep two (2) seconds after sending QUIT command to server.
3680 Affected file lib/silcclient/command.c.
3682 * Assure that if outgoing data buffer is pending do not force
3683 send any data. Affected file silcd/packet_send.c.
3685 * Assure that if outgoing data buffer is pending do not force
3686 send any data. Affected file lib/silcclient/client.c.
3688 * Implemented the backup router support when the primary router
3689 goes down. The servers and routers can now use the backup
3690 router as new primary router without loosing connectivity.
3692 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3694 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3695 in the server to indicate disabled entry. All data read
3696 from the connection will be ignored and no data is sent
3697 for entry that is disabled. Affected files are
3698 silcd/idlist.h, silcd/server.c.
3700 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * Created SFTP client and server test programs in the
3703 lib/silcsftp/tests directory.
3705 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * Implemented memory filesystem (virtual filesystem) for
3708 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3711 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3713 * Implemented the SFTP (SSH File Transfer Protocol) to the
3714 lib/silcsftp. It includes SFTP client and SFTP server
3717 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3719 * Moved lib/silccore/silcprotocol.[ch] to the
3720 lib/silcutil library.
3722 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3723 take variable argument list pointer as argument. Affected
3724 file lib/silcutil/silcbuffmt.[ch].
3726 * Added silc_buffer_set function that is used to set data
3727 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3728 Affected file lib/silcutil/silcbuffer.h.
3730 * Changed various routines in the core library to use the new
3731 silc_buffer_set instead of allocating new buffer only for
3734 * Added 64-bit value formatting and unformatting support to the
3735 silc_buffer_[un]format routines. Affected file is
3736 lib/silcutil/silcbuffmt.[ch].
3738 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3739 to includes/bitmove.h.
3741 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Fixed channel user mode saving in client library. Affected
3744 file lib/silcclient/command[_reply].c.
3746 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3748 * Defined the file transfer to the SILC Protocol. Added
3749 new packet type SILC_PACKET_FTP and defined File Transfer
3750 Payload. The mandatory file transfer protocol is SFTP
3751 (SSH File Transfer Protocol). Affected file in addition
3752 of the internet draft is lib/silccore/silcpacket.h.
3754 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3755 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3756 is used as part of backup router protocol when the primary
3757 router of the cell is back online and wishes to resume
3758 the position as primary router.
3760 * Redefined the MAC generation keys in the protocol. The
3761 same key is not used anymore in both direction. Both
3762 direction will now use different keys for sending and
3763 receiving. This fixes a potential security flaw. This
3764 change causes incompatibilities in the protocol.
3766 * Redefined also the MAC computation from the packet.
3767 An packet sequence number is now added to the MAC
3768 computation. This prevents possible replay attacks against
3769 the protocol. This change too causes incompatibilities
3772 Added `sequence' field to the SilcPacketContext to hold
3773 the current sequence number for the packet.
3775 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Added `created' field to the SilcIDListData in the file
3778 silcd/idlist.h to indicate the time when the entry was
3781 * Added `created' field to the SilcChannelEntry too. Affected
3782 file silcd/idlist.h.
3784 * Added `creation_time' aguments to all the announcement functions
3785 in the server. If it is provided then only the entries that
3786 was created after the provided time frame are actually
3787 announced. Affected file silcd/server.[ch].
3789 * The protocol says that the Channel ID's IP address must be
3790 based on the router's IP address. Added check for this in
3791 the silc_server_new_channel when processing incoming New Channel
3792 Payload. Affected file silcd/packet_receive.c.
3794 * Print out the correct version with --version in SILC client.
3795 Affected file irssi/src/silc/core/silc-core.c.
3797 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Fixed WHOWAS command to check for completnes of the client
3800 entry always, not just when the command is coming from client.
3801 Affected file silcd/command.c.
3803 * Added new function silc_server_packet_queue_purge to purge the
3804 outgoing data queue to the network. After the function returns
3805 it is guaranteed that the outgoing packet queue is empty.
3806 Affected file silcd/packet_send.[ch].
3808 * Purge the outgoing packet queue in the rekey protocol's final
3809 callback to assure that all rekey packets go to the network
3810 before quitting the protocol. Affected file silcd/server.c.
3812 * Added silc_client_packet_queue_parse as similar function as
3813 in server to the client library. The affected file is
3814 lib/silcclient/client.c.
3816 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Splitted silcd/server.c and created silcd/server_util.[ch]
3819 for utility functions.
3821 * Added new socket flag SILC_SF_DISABLED to indicate that the
3822 connection is open but nothing can be sent to or received from
3823 the connection. Affected file lib/silcutil/silsockconn.[ch].
3824 The checking for disabled socket is checked in the low level
3825 silc_socket_write and silc_socket_read functions.
3827 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3829 * Allow only nicknames and channel names that fits into the
3830 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3832 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3834 * When processing JOIN command reply in server check that if
3835 the channel exists in our global list we'll move it the local
3836 list. Affected file silcd/command_reply.c.
3838 * Fixed the check whether client is joined on the channel already
3839 in JOIN command. Affected file lib/silcclient/command.c.
3841 * Fixed the JOIN command reply to check whether the channel
3842 already exists. Affected file lib/silcclient/command_reply.c.
3844 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3846 * Added silc_ske_status_string to map the SKE error numbers
3847 to readable strings. The affected files are
3848 lib/silcske/silcske[_status].[ch].
3850 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3852 * Do not show the private channels on the WHOIS channel list
3853 as it is not allowed by the protocol. The affected file is
3856 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3858 * Assure that the packet length digged from the actual packet
3859 is something sensible in the silc_packet_decrypt_rest_special
3860 in lib/silccrypt/silcpacket.c.
3862 * Free and NULL the allocated pointer in silc_hmac_alloc if
3863 the HMAC allocation fails. The affected file is
3864 lib/silccrypt/silchmac.c.
3866 * Print the selected security properties to the log files in
3867 the server. Affected file silcd/protocol.c.
3869 * Add SKE's reference counter even if calling the completion
3870 callback manually. Otherwise it goes negative, although it
3871 does not cause any problems. The affected file is
3872 lib/silcske/silcske.c.
3874 * Remove the client entry with short timeout after giving the
3875 KILL command. Affected file lib/silcclient/command.c.
3877 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3878 case all found clients are already disconnected (WHOWAS would
3879 found them) in the server. Affected file silcd/command.c.
3881 * Update the last_receive (time of last data received) to be
3882 updated only when received private or channel message so that
3883 the idle time showed in WHOIS makes more sense.
3885 * Added boolean field `valid' in to the SilcClientEntry in the
3886 client library to indicate whether the entry is valid or not.
3887 This fixes the nickname change bug on channel when changing
3888 the nickname to be same than the old (like nick to Nick) the
3889 nickname formatter doesn't set the new nick anymore to Nick@host.
3890 Affected file lib/silcclient/idlist.[ch].
3892 * Now actually fixed the nickname changing on disconnection.
3893 Added new function silc_change_nick to the Irssi SILC Client.
3894 Affected file irssi/src/silc/core/client_ops.c,
3895 irssi/src/silc/core/silc-nicklist.[ch].
3897 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3899 * Check that the public key exists in the GETKEY command before
3900 trying to encode it. Affected file silcd/command.c.
3902 * Print some notifications on received public keys with GETKEY
3903 command in the Irssi SILC Client. Affected files are
3904 irssi/src/fe-common/silc/module-formats.[ch],
3905 irssi/src/silc/core/client_ops.c.
3907 * Use IDENTIFY command to resolve the server information in the
3908 GETKEY command instead of INFO command. Affected file
3909 lib/silcclient/command.c.
3911 * All command reply functions in the client library now calls
3912 the pending command reply callbacks even if an error has
3913 occurred. The server has done this a long time and now it was
3914 time to move the client library to this as well. Now all
3915 errors can be delivered back to the pending command reply
3916 callbacks if necessary. Affected files are
3917 lib/silcclient/command[_reply].[ch].
3919 * Change the nickname on disconnection back to the username
3920 because in reconnect the server will enforce it to it anyway.
3921 Affected file irssi/src/silc/core/silc-servers.c.
3923 * Fixed a config file parsing bug in the Irssi SILC client.
3924 Affected file irssi/src/silc/core/clientconfig.c.
3926 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3928 * When printing the channel mode on JOIN, verify that the
3929 channel key and channel's HMAC are valid. Affected file
3930 irssi/src/silc/core/client_ops.c.
3932 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3934 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3935 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3936 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3938 * Removed channel key rekey task deleting from the function
3939 silc_server_save_channel_key. Affected file silcd/server.c.
3940 Added explicit timeout task context instead that is used to
3941 delete the task if we are registering a new task before the
3942 new task has elapsed.
3944 * When channel key rekey occurs the client library now saves
3945 the old channel key for a short period of time (10 seconds) and
3946 is able to use it in case some is still sending channel
3947 messages encrypted with the old key after the rekey. Affected
3948 file lib/silcclient/[idlist.h|client_channel.c].
3950 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Added check to the silc_server_new_id_real to not accept
3953 new ID if it is the sender's own ID. Affected file is
3954 silcd/packet_receive.c.
3956 * Assure that we do not announce ourself or the one we've
3957 sending our announcements when we're router and are announcing
3958 servers to our primary router. Affected file silcd/server.c.
3960 * Fixed silc_server_command_identify_check_client to assemble
3961 correct WHOIS packet. It send corrupted WHOIS packet and
3962 caused problem with router to router connections. Affected
3963 file silcd/command.c.
3965 Fixed also silc_server_command_whois_check the same way
3966 as for the IDENTIFY command.
3968 * Added new SilcIDListStatus to the server in the SilcIDListData
3969 structure. The status now includes the current status of
3970 the entry (like registered, resolved etc.). Affected file
3971 silcd/idlist.[ch]. Defined a bunch of different status types
3972 as well. This replaced the old boolean registered field as well.
3974 Added resolve_cmd_ident field to the SilcClientEntry structure
3975 too so that if the entry is for example being resolved so
3976 another command may attach to the same pending command reply
3977 without requiring to resolve the same entry again. This concept
3978 should optimize the WHOIS and the IDENTIFY resolving under
3979 heavy load by taking away unnecessary resolving for entries
3980 that are being resolved already.
3982 Added support for adding multiple pending commands for one
3983 command idenfier. Affected file silcd/command[_reply].[ch].
3985 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3986 before deleting the data. Otherwise the hash table will have
3987 freed data in comparison functions. Affected file is
3988 silcd/command_reply.c.
3990 * Fixed silc_idlist_replace_client_id to add the new entry to
3991 the cache with NULL nickname. Otherwise there will be invalid
3992 memory as the nickname after the nickname is freed. Affected
3993 file silcd/packet_receive.c.
3995 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3996 saved into wrong slots because the previous number of entries
3997 was not taken into account. Affected file silcd/idlist.c.
3998 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4000 * If we are router and we receive JOIN notify to a channel that
4001 does not have any users then notified client is marked as the
4002 channel founder, as it is it. The affected file is
4003 silcd/packet_receive.c
4005 * Added to the extended hash table API's table_del_*ext functions
4006 the destructor as argument too, so that the caller can decide
4007 which destructor to use or whether to use destructor at all.
4008 Affected file lib/silcutil/silchashtable.[ch].
4010 * Fixed ID Cache purging. It actually deleted the entries from
4011 the hash table after the data was freed. The hash table ended
4012 up comparing freed memory. The affected file is
4013 lib/silccore/silcidcache.c.
4015 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4017 * Fixed Irssi SILC client's KILL command's HELP syntax.
4019 * The USERS command now resolves the detailed user information
4020 if the userinfo field is missing. Affected file is
4021 lib/silcclient/command_reply.c.
4023 * Do not print error in silc_file_read if the read file does
4024 not exist. Just silently return NULL. Affected file is
4025 lib/silcutil/silcutil.c.
4027 * Fixed the silc_log_output to not wine about NULL filename
4028 and to not create some bogus " " filename. Affected file is
4029 lib/silcutil/silclog.c.
4031 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4033 * Fixed various printing bugs on the user interface in the
4034 Irssi SILC Client. Minor changes that were forgotten from
4037 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Fixed the configure.in.pre and the compilation and distribution
4040 environment to support the new autoconf 2.52. That version is
4041 now required to compile the CVS trunk.
4043 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4045 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4046 to generally parse user@fqdn format strings. Affected file
4047 lib/silcutil/silcutil.c.
4049 * Added nickname_format and nickname_force_format fields to the
4050 SilcClientParams structure. The first one defines the format
4051 for the nicknames that the library will enforce if the receives
4052 multiple same nicknames. The second one is boolean value and
4053 can be used to force the library to always enforce the format
4054 to the nicknames regardles whether there are multiple nicknames
4055 or not. This configurable formatting was employed to flexibly
4056 support accessing multiple nicknames from the user interface.
4057 The userinterface can now set the nicknames to what ever format
4058 they prefer. Affected file lib/silcclient/silcapi.h.
4060 Added function silc_client_nickname_format to the file
4061 lib/silcclient/idlist.c. It performs the nickname formatting.
4063 Added new field `hostname´ to the SilcClientEntry context.
4064 It holds the hostname of the client. Affected file is
4065 lib/silcclient/idlist.h.
4067 * Irssi SILC Client sets the nicknames in nick@hostn format.
4068 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4069 irssi/src/silc/core/silc-core.c.
4071 The WHOIS printing now also shows both the real nickname and
4072 the formatted nickname so that user knows how to access the
4073 user if there are multiple same nicknames cached. Affected
4074 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4075 printing formatting too to take the hostname now as a separate
4076 argument. The Affected file is
4077 irssi/src/fe-common/silc/modules-formats.[ch].
4079 * Changed the silc_client_get_clients_local to accept the formatted
4080 nickname as argument. It accepts the real nickname too but the
4081 formatted nickname can be used to find the true entry from
4082 multiple entries. Affected file lib/silcclient/silcapi.h and
4083 lib/silcclient/idlist.c.
4085 * Added nickname_format_parse field to the SilcClientParams.
4086 It is a callback function provided by the application to parse
4087 the nickname out of the formatted nickname string. The library
4088 calls it to get the nickname from the formatted string. Since
4089 the application generally knows better the format of the nickname
4090 string it parses it instead of the library, even though library
4091 encodes the formatted string. If the callback function is not
4092 provided then the library will use the string as is. The
4093 affected file is lib/silcclient/silcapi.h.
4095 * All the nickname strings passed to the client library in
4096 commands are now expected to be formatted nickname strings.
4097 If the command does not support the formatted nickname string
4098 it will assume that the sent string is the actual nickname.
4099 Affected file lib/silcclient/command.c.
4101 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4103 * Added public key authentication support to OPER and SILCOPER
4104 commands in the client library. Affected file is
4105 lib/silcclient/command.c.
4107 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4109 * Changed the get_auth_methdod client operation to be asynchronous.
4110 It can be async if the application resolves the authentication
4111 method from the server during the negotiation. Added new
4112 SilcGetAuthMeth completion callback that the application will
4113 call after resolving the authentication method.
4115 Added function silc_client_request_authentication_method that
4116 the application can use to resolve the authentication method
4117 from the server. Added also SilcConnectionAuthRequest callback
4118 that the library will call after the server has replied. The
4119 application can call this function if it does not know the
4120 current authentication method.
4122 Affected files are lib/silcclient/client.c and
4123 lib/silcclient/silcapi.h.
4125 * The Irssi SILC client now automatically resolves the authentication
4126 method incase any configuration information is not present (and
4127 currently there never is). The affected file is
4128 irssi/src/silc/core/client_ops.c.
4130 * Fixed public key authentication from the client library.
4131 Affected file lib/silcclient/protocol.c. Changed also the
4132 protocol specification about the public key authentication in
4133 the connection authentication protocol. The actual data to be
4134 signed is now computed with a hash function before signing.
4136 * Fixed the public key authentication from the server as well.
4137 Affected file silcd/protocol.c.
4139 * Removed the mlock()'s from the memory allocation routines.
4140 Affected file lib/silcutil/silcmemory.c. The ./configure does
4141 not check anymore for the mlock(). Affected file is
4144 * Fixed USERS command in server to allow the execution of the
4145 command for private and secret channels if the client sending
4146 the command is on the channel. Affected file silcd/command.c.
4148 * Fixed silc_client_get_clients_local to return the clients
4149 count correctly. It could return wrong value. Affected file
4150 lib/silcclient/idlist.c.
4152 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4154 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4155 types. The assembler optimizations seemed not to like 64-bit
4156 data types. The assmebler optimizations thus are now enabled
4157 also for BSD systems as opposed to only enable them for Linux.
4159 * Do not check for threads at all on BSD systems. Affected
4160 file configure.in.pre.
4162 * Removed -n and -h options from the Irssi SILC Client since
4163 they are not used in silc.
4165 * Fixed the prime generation to assure that the first digit
4166 of the generated random number is not zero since our conversion
4167 routines does not like number strings that starts with zero
4168 digit. If zero digit is seen the random number is regenerated.
4169 This caused some corrupted RSA keys when the zero first digit
4170 was met. Affected file lib/silcmath/silcprimegen.c.
4172 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4174 * Fixed WIN32 configuration in the ./configure script.
4175 Fixed to include xti.h on environments that has it.
4176 Patches by Carsten Ilchmann and andrew.
4178 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4180 * Changed the silc_id_create_client_id to be collision
4181 resistant. It is now assured that there cannot be created
4182 two same client ID's. I suspect that some weird bugs in
4183 the server were actually caused by duplicate Client IDs.
4184 Affected file silcd/serverid.[ch]. A router receiving
4185 new ID now also assures and informs the sending server
4186 if the ID caused collision.
4188 * Changed the silc_id_create_channel_id to also assure that
4189 there are no collisions.
4191 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * Statement about ignoring the Mutual Authentication flag when
4194 performing rekey with PFS was a bit misleading. It is ignored
4195 if it was set in the initial negotiation, it cannot be even
4196 set in the rekey. Fixed in the ke-auth draft. Started the
4197 new versions of the protocol drafts in the doc/.
4199 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4201 * Fixed a bug in silc_client_command_identify_save when saving
4202 new channel information. The channel name was no duplicated
4203 and caused crash on exit. Affected file is
4204 lib/silcclient/command_reply.c.
4206 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * Fixed the getkey command handling in the server. Send just
4209 empty OK reply to the sender if the key could not be fetched
4210 (but everything else was ok, like the key just was not available).
4211 Changed the public key parameter to optional in the protocol
4212 specs so that empty OK reply can be sent. Affected file
4215 Added a message to Irssi SILC client to tell to user if the
4216 server did not return a public key.
4218 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4220 * Fixed a channel key regeneration bug. It registered new
4221 timeout tasks exponentially until all system resources were
4222 used. Affected file silcd/server.c.
4224 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4226 * Added the SILC Document generator to the scripts/silcdoc.
4227 It can be used to generate the Toolkit Reference Manual out
4228 of the source tree. Internally it will also use the RoboDoc
4229 generator now imported in util/robodoc.
4231 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4233 * Added couple of return's in rekey protocol if error orccurred
4234 during the protocol. The execution must be terminated.
4235 Affected file silcd/protocol.c. Also, terminate the protocol
4236 always with timeout.
4238 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * The client's Client ID was created initally from the wrong
4241 nickname (it could have been in format nick@host) in the
4242 silc_server_new_client. Affected file silcd/packet_receive.c
4244 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4246 * Added some SILC_LOG_ERROR's to various error conditions
4247 if client could not be added to ID cache. Affected files
4248 silcd/packet_receive.c and silcd/server.c.
4250 * When client's sock->user_data is freed, NULL also the
4251 client->router and client->connection pointers. Added check
4252 for these pointers being NULL to various places around the
4253 code. Affected file silcd/server.c.
4255 * Added client->data.registered == TRUE checks to various
4256 places around the code to assure that unregistered client's
4257 are not handled when it is not allowed. Affected file
4260 * Added `bool registered' fields to all
4261 silc_idlist_[server|client]_get_* routines to indicate whether
4262 the fetched client needs to be registered or not. Affected
4263 file silcd/idlist.[ch].
4265 * Add your own entry as registered to the ID cache in the
4266 server. Affected file server.c.
4268 * Fixed a bug in silc_server_new_server. The SilcServer was
4269 set as the new server's context instead of SilcServerEntry.
4270 This naturally caused some weird bugs.
4272 * Added "updated" field the SilcChannelEntry which indicates
4273 the time since the channel entry was last accessed. This
4274 can be used to determine whether it is necessary to
4275 announce the channel after backup resuming protocol.
4276 Affected files silcd/idlist.[ch].
4278 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4280 * Do not delete the channel rekey task when adding it
4281 for in silc_server_create_channel_key.
4283 * Changed the silc_server_create_channel_key to return
4284 TRUE or FALSE to indicate the success of the channel key
4287 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4289 * Fixed MSVC++ project files and added missing files to
4290 Makefiles under win32/.
4292 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4294 * Do not add TCP_NODELAY flag if the operating system
4295 does not have it defined. Affected files are
4296 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4298 * Fixed buffer overflow from Irssi SILC Client. Affected
4299 file irssi/src/fe-common/core/themes.c.
4301 * Fixed double free in client library in the file
4302 lib/silcclient/client.c when disconnecting from server.
4304 * Applied double free patch from cras to Irssi SILC client.
4305 Affected files irssi/src/core/[modules/expandos].c
4307 * Fixed the disconnection handling to Irssi SILC Client.
4308 The application must call silc_client_close_connection
4309 in ops->connect client operation in case of failure of
4310 the connection. Affected file is
4311 irssi/src/silc/core/client_ops.c.
4313 * Do not set sock->protocol to NULL in the function
4314 silc_client_close_connection after executing the protocol's
4315 final callback since the sock might not be valid anymore.
4316 Affected file lib/silcclient/client.c.
4318 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4320 * Do not enable SILC_THREADS if the linking with libpthread
4321 did not happen. Affected file configure.in.pre.
4323 * Added notion to protocol specification that server must
4324 verify the sent authentication payload with CMODE when
4325 setting the channel founder key. Implemented it to the
4326 server. Affected file silcd/command.c.
4328 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4330 * Added _EXTRA_DIST SILC distribution variable to the
4331 distributions file. It is used to conditionally add extra
4332 files or directories to the specific distribution. Affected
4333 files ./prepare, Makefile.am.pre and distributions.
4335 Removed the `_' from the start of the distribution names.
4338 * Added README.WIN32 for instructions to compile the Toolkit
4341 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4343 * Fixed a double free in disconnection in the server. Affected
4344 file is silcd/server.c.
4346 * Fixed the lib/silcske/groups.c to work now also with GMP
4347 MP library. The string conversion did not work when using
4348 specific base and the base is indicated in the string as well.
4350 * Created win32/ directory which now includes MSVC++ specific
4351 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4352 It will appear only in the toolkit distribution
4354 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Changed the key material distribution function in case when
4357 the hash output is too short. The data is now concatenated
4358 a bit differently than it used to. Made the change to the
4359 SKE protocol specification.
4361 * Added better GMP detection to configure.in.pre. A patch
4364 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4366 * Fixed a minor bug in SKE that might cause some problem on
4367 some platforms. Affected file lib/silcske/silcske.c.
4369 * Added the cookie checking for initiator in the SKE. It checks
4370 that the responder returns the sent cookie unmodified. The
4371 affected file is lib/silcske/silcske.c. Added new SKE
4372 error type INVALID_COOKIE that can be sent during the
4373 negotiation. Fixed some memory leaks as well.
4375 * Added the "invalid cookie" error message to Irssi SILC client's
4378 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4380 * Added `task_max' field to the SilcClientParams to indicate
4381 the maximum tasks the scheduler can handle. If set to zero,
4382 default values are used. Affected file lib/silcclient/silcapi.h.
4384 * Fixed memory leaks in silc_client_close_connection. Affected
4385 file lib/silcclient/client.c.
4387 * Added silc_client_del_client_entry to client library to free
4388 all memory of given client entry. Affected file is
4389 lib/silcclient/idlist.[ch].
4391 * Added new functions silc_client_del_channel and
4392 silc_client_del_server to delete channel and server entries.
4393 Affected file lib/silcclient/[silcapi.h/idlist.c].
4395 * Removed silc_client_del_client_by_id from silcapi.h.
4397 * Fixed the INFO command to return the server's own info
4398 correctly when querying by Server ID. Affected file is
4401 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4403 * Removed the non-blocking settings in WIN32 code in the
4404 silc_sock_[read/write] and added SleepEx instead. Affected
4405 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4406 of input data is now checked with FIONREAD and ioctlsocket.
4408 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4410 * Call silc_schedule_task_del_by_context in the
4411 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4412 Affected file lib/silccore/silcprotocol.c.
4414 * Call silc_protocol_cancel for active protocols in the
4415 silc_server_close_connection if the funtion
4416 silc_server_free_sock_user_data has not been called.
4417 Affected file silcd/server.c.
4419 * Generic tasks cannot be deleted using the del_by_fd
4420 task deleting function since generic tasks does not match
4421 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4423 * Added a notion to SILCOPER help file that the SILCOPER works
4424 only on router server, not on normal server.
4426 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4428 * Added for WIN32 support for the new scheduler as well.
4429 Affected file lib/silcutil/win32/silcwin32schedule.c.
4431 * Fixed the SHA1 implementation to work on various platforms.
4433 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4435 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4436 API. It is part of the scheduler now. Everything else is
4437 as previously but some functions has changed their names.
4438 Checkout the lib/silcutil/silcschedule.h for the interface.
4439 Updated all applications to use the new interface. Affected
4440 files are lib/silcutil/silcschedule.[ch].
4442 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4444 * Found a bug in the SKE implementation. The HASH value,
4445 specified by the protocol, was not computed correctly. The
4446 public key of the responder was not added to the computation
4447 even though it is mandatory. Affected file lib/silcske/silcske.c.
4448 This unfortunately causes incompatibilities with older
4449 clients and servers.
4451 * Added WIN32 specific network init and uninit functions:
4452 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4453 the Winsock2. Affected file lib/silcutil/silcnet.h and
4454 lib/silcutil/win32/silcwin32net.c.
4456 * Set the socket always to nonblocking mode on WIN32 after
4457 reading data or writing data. Affected file is
4458 lib/silcutil/win32/silcwin32sockconn.c.
4460 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4462 * Fixed various compilation problems under WIN32. Affected
4463 files lib/silcutil/win32/silcwin32thread.c and
4464 lib/silcutil/win32/silcwin32schedule.c.
4466 * Removed all _internal.h #includes from public header
4467 files. Internal headers must never be included from
4470 Removed also the lib/silcske/payload_internal.h file.
4472 * All include files that may be needed (public and some others
4473 included by the public headers) by application developers are
4474 now copied to the ./includes directory. It does not copy any
4475 internal headers. Affected file Makefile.defines.pre and all
4476 Makefile.am's under lib/ and subdirs.
4478 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4480 * Do not change the ~/.silc directory's permissions automatically.
4481 Affected file irssi/src/silc/core/clientutil.c.
4483 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4485 * Do not cancel the protocol in silc_server_close_connection
4486 it might cause recursion. Now cancelled in the function
4487 silc_server_free_sock_user_data. Affected file silcd/server.c.
4489 * Fixed the silc_server_remove_clients_by_server to regenerate
4490 the channel keys correctly finally. Added also new function
4491 silc_server_remove_clients_channels to actually do it.
4492 Affected file silcd/server.c.
4494 * Fixed the silc_server_new_channel to not crash by giving
4495 wrong router to the new channel. Affected file is
4496 silcd/packet_receive.c.
4498 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4500 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4501 which is given as argument to the silc_client_alloc now.
4502 It can be used to configure the client and set various parameters
4503 that affect the function of the client.
4505 * The USERS command in server did not check whether the channel
4506 is private or secret. Affected file silcd/command.c.
4508 * Added new argument to the USERS command in protocol specification.
4509 The USERS command now can take the channel name as argument
4510 as well. Added support for this in client and server and
4511 updated the protocol specs.
4513 * Completed the GETKEY command in client. It can be now used
4514 to fetch also servers public key not only some clients.
4515 Affected files lib/silcclient/command[_reply].c.
4517 * Added silc_client_get_server to return server entry by the
4518 server name. Affected files lib/silcclient/silcapi.h and
4521 * Redefined the IDENTIFY command in protocol specification to be
4522 more generic. It now can be used to query information about
4523 any entity in the SILC Network, including clients, servers and
4524 channels. The query may be based either the entity's name
4525 or the ID. Added support for this in both client and server.
4527 Affected files silcd/command.c and lib/silcclient/command.c
4528 and command_reply.c.
4530 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4531 the _from_client and _from_server functions. Affected file
4534 * Added silc_client_get_channel_by_id_resolve to the file
4535 lib/silcclient/silcapi.h to resolve channel information by
4536 its ID. Added also silc_client_get_channel_by_id that
4537 does not resolve it from the server.
4539 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4541 * Added SilcServerEntry context into the client library
4542 to represent one server. The INFO command now allocates
4543 these to save the resolved server info. For now on the
4544 client library will also keep information about servers,
4545 connected and resolved with INFO.
4547 The INFO command now allocates the SilcServerEntry context
4548 and saves the server info there. The COMMAND_REPLY in
4549 the INFO now returns the parameters to application in
4550 same order as defined in the protocol specification.
4552 The entries are cached in the client->server_cache.
4554 * The INFO command is now issued after received the Client ID
4555 from the server. Affected file lib/silcclient/client.c.
4557 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4558 to the application as the mode changer might be server.
4559 It is guaranteed that NULL is not returned anymore to the
4560 application. Affected file lib/silcclient/client_notify.c.
4562 The ID Type is now also passed to the application so that
4563 it can check whether the returned entry is SilcClientEntry
4566 Added new function silc_client_get_server_by_id to return
4567 the server entry by ID. Affected files are the
4568 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4570 * Do not create the channel in the Irssi SILC Client when issuing
4571 the JOIN command but when received the sucessful JOIN command
4572 reply. Otherwise the channel might get created even though we
4573 could not join it. The Affected file is
4574 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4576 * Fixed a channel joining bug in router. The router must also
4577 check the channel modes, invite and ban lists etc. when serving
4578 the JOIN command sent by normal server. Affected file is
4579 silcd/command.c. The router now resolves the client's
4580 information from the server who sent the JOIN command if it
4581 does not know it, and processes the JOIN command only after
4584 * Changed the SilcCommandCb to take new argument; void *context2.
4585 Affected file lib/silccore/silccommand.h
4587 The second argument in the command callbacks in the server now
4588 includes the SilcServerCommandReplyContext if the command was
4589 called as pending command callback from the command reply.
4590 Otherwise it is NULL. When called as pending the status of the
4591 command reply will be checked and if it was erronous the
4592 error will be sent to the original sender of the command.
4593 This way the client always receives the error messages even
4594 though the server was actually the one who received the error
4595 when it resent the command to router, for example. Affected
4596 files silcd/command[_reply].[ch].
4598 * Fixed sending WHOWAS command's error message to client if
4599 the requested client could not be found. It was missing.
4602 * Changed the CMODE and CUMODE commands reply arguments in the
4603 protocol specification. The Channel ID is now sent in both
4604 of the commands to identify the channel. Implemented this
4605 new feature to the client and server. Affected files
4606 lib/silcclient/command_reply.c and silcd/command.c.
4608 * Made better checks for invite and ban lists in the JOIN
4609 command in server. Affected file silcd/command.c.
4611 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4613 * The server now performs the incoming host IP/DNS lookup
4614 using the silc_socket_host_lookup and thus does not block
4615 the server anymore. Affected file silcd/server.c.
4617 * Completed the multi-thread support for SILC Scheduler in
4618 the lib/silcutil/silcschedule.c.
4620 * Fixed the configure.in.pre to detect the pthread correctly
4623 * Fixed a deadlock in silc_task_queue_wakeup in the file
4624 lib/silcutil/silctask.c.
4626 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4628 * Added new function silc_schedule_wakeup that is used in
4629 multi-threaded environment to wakeup the main thread's
4630 schduler. It needs to be used when a thread adds a new task
4631 or removes a task from task queues. After waking up, the
4632 scheduler will detect the task queue changes. If threads
4633 support is not compiled in this function has no effect.
4634 Implemented the wakeup mechanism to both Unix and WIN32
4635 systems. Affected files are lib/silcutil/silcschedule.[ch],
4636 lib/silcutil/unix/silcunixschedule.c and the
4637 lib/silcutil/win32/silcwin32schedule.c.
4639 * Added new function silc_task_queue_wakeup to wakeup the
4640 scheduler by the specified task queue. Affected file
4641 lib/silcutil/silctask.[ch].
4643 * The silc_socket_host_lookup_start now wakes up the scheduler
4644 after adding the timeout task. Affected file is
4645 lib/silcutil/silcsockconn.c.
4647 * The silc_socket_host_lookup is synchronous now if the threads
4648 support is not compiled in. However, the callback is still
4649 called asyncronously through the scheduler, anyway. Affected
4650 file lib/silcutil/silcsockconn.c.
4652 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4654 * Added new function silc_socket_host_lookup to perform
4655 asynchronous IP and FQDN lookups for the socket connection.
4656 Affected files lib/silcutil/silcsockconn.[ch].
4658 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4660 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4661 that may or may not compile the mutex support in.
4663 Changed the silc_mutex_alloc interface. It allocates the
4664 mutex now to the sent pointer and returns TRUE or FALSE.
4666 Affected file lib/silcutil/silcmutex.h.
4668 * Wrote the SILC Task Queue interface to support multi-threads.
4669 Affected file lib/silcutil/silctask.[ch].
4671 * Wrote the SILC Scheduler to support multi-threads. Affected
4672 file lib/silcutil/silcschedule.c.
4674 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4676 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4677 in lib/silcutil/win32/.
4679 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4681 * Defined SILC Mutex API and SILC Thread API and implemented
4682 them for Unix. Affected files are
4683 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4684 lib/silcutil/unix/silcunixmutex.c and
4685 lib/silcutil/unix/silcunixthread.c.
4687 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4689 * Fixed the silc_server_remove_clients_by_server's channel
4690 key re-generation. The hash table handling was incorrect
4691 and would not work with many channels. Affected file is
4694 * Fixed some memory leaks around the server code.
4696 * Rewrote the silc_server_get_users_on_channel to support IPv6
4697 based Client ID's. Affected file silcd/server.c.
4699 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4700 specification. However, a separate document must be written
4701 to define the detailed signing procedure and the payload
4702 associated with the flag. Defined the flag to the
4703 lib/silccore/silcchannel.h as well.
4705 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4707 * Changed the dynamic tables to static size tables in the
4708 lib/silccrypt/silchmac.c.
4710 * Removed GCC dependencies from the code. A patch by cras.
4712 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4714 * Do not show the error "Error receiving packet bla bla"
4715 in server if it really was not an error (-2 means that reading
4716 is pending). Affected file silcd/server.c.
4718 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4720 * Fixed a possible crash in silc_server_remove_clients_by_server
4721 in silcd/server.c. Fixed there also some memory leaks.
4723 * Fixed the silc_idlist_replace_client_id. It could replace
4724 wrong key in the hash table. Affected file silcd/idlist.c.
4726 * Do not check whether there are global users on the channel
4727 if the channel->global_users is FALSE. Affected functions
4728 silc_server_remove_from_one_channel and
4729 silc_server_remove_from_channels in silcd/server.c. Also,
4730 do not check if the removed client is local as we can be
4731 sure that global client was not removed from the channel
4732 and checking for global users is not needed.
4734 * The silc_server_remove_clients_by_server now re-generates
4735 the channel keys correctly for those channels that had
4736 clients removed from them. Affected file silcd/server.c.
4738 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4740 * Found the reason of random crashes in the server. We weren't
4741 ignoring the SIGPIPE signal (which can be sent in write())
4742 and it crashed the server. Affected file silcd/silcd.c.
4744 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4746 * Assure that sock->user_data is not NULL in the function
4747 silc_server_packet_send in silcd/packet_send.c.
4749 * Disconnect the remote connection if it could not be added
4750 to any ID lists in the server. The affected file is
4753 * Check in silc_server_packet_send[_real/dest] that the
4754 socket is not disconnecting and ignore the data if it is.
4755 Affected file silcd/packet_send.c.
4757 * Define inline to __inline on native WIN32 compilation.
4758 Affected file includes/silcwin32.h.
4760 * Added some explicit type casts for inline code since MSVC
4761 require them. Affected files lib/silcutil/silcbuffer.h,
4762 lib/trq/silcdlist.h and lib/trq/silclist.h.
4764 * Print warning in log files from now on if the packet
4765 decryption fails. Affected file silcd/server.c.
4767 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4769 * Changed the `say' client operation's interface to accept
4770 new `type' argument to indicate the type of the message sent
4771 by the library. The application may filter the library's
4772 messages according the type. The affected file is the
4773 lib/silcclient/silcapi.h.
4775 * Added two new functions to lib/silcclient/silcapi.h:
4776 silc_client_del_client and silc_client_del_client_by_id.
4777 Affected file lib/silcclient/idlist.c.
4779 * Moved the clientincludes.h from includes/ to silc/ and
4780 serverincludes.h from includes/ to silcd/.
4782 * The modes for the CMODE and CUMODE are now passed as
4783 uint32 for application with COMMAND_REPLY. The affected
4784 file is lib/silcclient/command_reply.c.
4786 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4788 * /WHOIS without arguments shows client's own information.
4789 Affected file lib/silcclient/command.c.
4791 * Changed PING to not accept any arguments. The specs
4792 says that client can ping only the connected server so
4793 requiring an argument is not needed. Affected file is
4794 lib/silcclient/command.c.
4796 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4798 * Fixed a fatal bug in private message sending and reception
4799 encryption and decryption when using private message keys.
4800 The implementation was incorrect and did not follow the
4801 specification. It causd that some of the message were
4802 lost since it did not use the sending and receiving keys
4803 as the protocol suggests. This has been fixed and will cause
4804 incompatibilities with older clients when sending private
4805 message encrypted with private message keys. Affected files
4806 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4807 and various other in Irssi SILC Client.
4809 Added `responder' boolean argument to the functions
4810 silc_client_add_private_message_key[_ske] to indicate when
4811 the key is added as responder or initiator of the key
4814 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4816 * Removed the silc_ske_check_version function and created
4817 a SilcSKECheckVersion callback. Added also a function
4818 silc_ske_set_callbacks that is now used to set all SKE
4819 callbacks. The callback functions are not given to
4820 the SKE functions anymore, but this function is used to
4823 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4825 * Added `silc_version' argument to the silc_client_alloc
4826 to define the version of the application for the library.
4827 The library will use the version string to compare it
4828 against the remote host's (usually a server) version
4829 string. Affected file lib/silcclient/silcapi.h
4831 * Added the KE protocol context to Key Agreement context
4832 in client library so that we can abort the SKE if it
4833 is in process when we get timeout. Affected file is
4834 lib/silcclient/client_keyagr.c.
4836 * Do not resolve the client ID forever if it returns in the
4837 first time that such client does not exist. This was done
4838 for example with private message. Affected file is
4839 lib/silcclient/client_prvmsg.c.
4841 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4843 * Do not add regex.h for WIN32. The affected file
4844 includes/silcincludes.h.
4846 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4847 not work yet 100%. It generates the DLL's automatically
4848 when compiling with --with-win32 under cygwin.
4850 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4852 * lib/contrib/regex.c is not compiled on WIN32.
4854 * Added silc_net_get_socket_opt function to the
4855 lib/silcutil/silcnet.h.
4857 * Added includes/silcwin32.h for WIN32 specific includes
4860 * Do not use ptime structure or any of the posix process
4861 functions on WIN32 in lib/silccrypt/silrng.c.
4863 * Added silc_gettimeofday to provide generic function
4864 for struct timeval on all platforms. Added the function
4865 to lib/silcutil/silcutil.h.
4867 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4869 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4870 library as they clearly belong there. As a plus side we
4871 can make the actual socket connection routines platform
4874 Added also new generic function silc_socket_read and
4875 silc_socket_write (that used to be silc_packet_[read/write].
4876 The implementation of these are platform specific.
4878 * Added WIN32 specific routines of silc_socket_[read/write]
4879 to lib/silcutil/win32/silcwin32sockconn.c.
4881 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4883 * Added preliminary support for native WIN32 compilation under
4884 cygwin (using the -mno-cygwin option for GCC) to the
4885 ./configure.in.pre. The --with-win32 now prepares the
4886 compilation for native WIN32.
4888 * Rewrote the SILC Scheduler interface in the file
4889 lib/silcutil/silcschedule.h. The scheduler is now context
4890 based and does not have anymore any global static scheduler.
4891 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4892 and created lib/silcutil/win32 directory for WIN32 based
4895 * Added Unix specific network routines to the
4896 lib/silcutil/unix/silcunixnet.c and the old
4897 lib/silcutil/silcnet.c includes now only generic routines.
4899 Added WIN32 specific network routines to the
4900 lib/silcutil/win32/silcwin32net.c.
4902 * Added Unix specific utility functions from the
4903 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4905 * Added WIN32 SILC Scheduler to the file
4906 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4909 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4911 * Do not handle JOIN notify in the server if the target client
4912 is not registered (idata->registered == FALSE). The affected
4913 file is silcd/packet_receive.c.
4915 * Update the nickrec->founder in event_cumode in the Irssi SILC
4916 client. Affected file irssi/src/silc/core/silc-channels.c.
4918 * Fixed the CUMODE_CHANGE notify handling in the server when
4919 server and router are announcing their clients on channels.
4920 Now the mode changes are saved and notified correctly. The
4921 affected file is /silcd/packet_receive.c.
4923 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4924 They really did not replace the cache entry in the ID Cache.
4925 Now they do that. Affected file silcd/idlist.c.
4927 * Fixed the KICK notify handling in the Irssi SILC client to
4928 update the channel records so that the kicked client does not
4929 appear to be on the channel. The affected file is
4930 irssi/src/silc/core/silc-channels.c.
4932 * Always update the conn->current_channel when executing command
4933 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4935 * Fixed the KILL notify handling in Irssi SILC client to remove
4936 the killed client on all channels.
4938 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Fixed the silc_parse_command_line to remove extra spaces
4941 from the start and end of the arguments. Affected file is
4942 lib/silcutil/silcutil.c.
4944 * Cancel and free any active protocol in the function
4945 silc_server_close_connection. Affected file silcd/server.c.
4947 * Cancel and free any active protocol in the function
4948 silc_client_close_connction. Affected file is
4949 lib/silcclient/client.c.
4951 * Do not execute the KILL command for clients that are in
4952 history (ie. they are not in the network). Affected file is
4955 * Fixed KILL notify handling, client does not crash anymore.
4956 Affected file irssi/src/silc/core/silc-channels.c.
4958 * Reduced the default packet buffer size from 2048 to 1024 in
4959 lib/silccore/silcpacket.c.
4961 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4962 counter to the SKE context that is incresed when the SKE library
4963 performs async operation outside the library. If the outside
4964 process frees the SKE context and FREED status will be set
4965 and the library will detect after the sync operation that the
4966 libary is freed. The affected files are
4967 lib/silcske/silcske[_status].[ch].
4969 * Resolve the client entry information in the function
4970 silc_client_channel_message to assure that NULL pointer is not
4971 passed as client entry to the application. */
4973 * Fixed the task timeout calculation to assure that there is
4974 never negative timeouts. The affected file is
4975 lib/silcutil/silcschedule.c.
4977 * Fixed the channel user mode notification sending in server.
4978 It was sent point-to-point to the router (or to server by router)
4979 but it needs to be destined to a channel. The routines now
4980 supports sending the channel user mode notifys to the channels
4981 when announcing clients and channels. Affected files are
4982 silcd/server.c and silcd/packet_receive.c.
4984 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4985 It did not actually replace the old channel entry in the cache.
4986 Affected file lib/silcclient/client_notify.c.
4988 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Fixed a possible crash in silc_packet_send_prepare. It now
4991 assures always that there is enough space in the buffer and
4992 at the tail area of the buffer (for MAC).
4994 Fixed the inbound buffer reallocation in silc_packet_read.
4995 It was old code and did not handle the reallocation correctly.
4998 The affected file is lib/silccore/silcpacket.c.
5000 * Fixed buffer overflow in silc_parse_nickname in the file
5001 lib/silcutil/silcutil.c.
5003 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * make install generates new server keys only if there is not
5008 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5011 Added check that if the NOREPLY is set then we will not send
5012 the away message. This avoids infinite loop of away messages
5013 if both clients are away. The affected file is
5014 lib/silcclient/client_prvmsg.c.
5016 * Fixed client crash if /NICK was given without arguments.
5017 Affected file lib/silcclient/command.c.
5019 * Server does not send the invite list in INVITE command back
5020 to the client if the list was not altered. Added this notion
5021 to the protocol spec as well. Affected file silcd/command.c.
5023 Fixed possible crash in INVITE command by checking the
5024 value of silc_server_get_client_route command.
5026 * Fixed the INVITE notify type handling. The arguments are now
5027 taken in correct order and client does not crash. The affected
5028 file is irssi/src/silc/core/silc-channels.c.
5030 Removed the "Inviting xxx to channel" message from the
5031 client library away and let the application handle it.
5032 Affected file lib/silcclient/command.c. Added that message
5033 to Irssi SILC client's message formats.
5035 * Fixed CMODE command crash in client. It now checks the
5036 amount of arguments correctly and does not crash. The affected
5037 file is lib/silcclient/command.c.
5039 * Do not create new channel automatically in silc_channels_join
5040 but check whether the channel by that name already exists.
5041 Affected file irssi/silc/core/silc-channels.c.
5043 * Do not send the SERVER_SIGNOFF to router if the disconnected
5044 entity was the router. Affected file silcd/server.c.
5046 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5047 SILC client as it was missing from there.
5049 Added the handling of the KICK notify to the Irssi SILC client
5050 as it was missing. Added "you have been kicked" message to
5051 Irssi SILC client's message modules formats.
5053 Added the handing of the KILL notify to the Irssi SILC client
5054 as it was missing. Added the kill message module formats
5057 The affected file is irssi/src/silc/core/silc-channels.c.
5059 * The router did not save the channel mode the server announced.
5060 Affected file silcd/packet_receive.c.
5062 * Fixed a possible crash in INFO command in server. If the
5063 server did not provide the server info it crashed. Affected
5064 file silcd/command.c.
5066 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Fixed the GETKEY command in the server to check also the
5069 global list. Otherwise the GETKEY would not work correctly
5070 in normal SILC server. Affected file silcd/command.c.
5072 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Fixed GETKEY crash, it crashed if the command did not succseed.
5076 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5079 is now real and not just an macro interface to GMP.
5081 Removed the entire GMP from the source tree and imported new
5082 NSS MPI library instead. Reason for removing GMP is that it is
5083 extremely large and compiles extremely slow. The NSS MPI
5084 is only a few files and compiles in less than 10 seconds.
5085 The speed is also about the same as GMP. The MPI is imported
5086 to lib/silcmath/mpi.
5088 If the system has GMP installed we will still use the GMP.
5089 If it is not then the NSS MPI will be compiled.
5091 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Merged a long nickname (127 characters long) crash bugfix from
5094 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5096 * Merged a freed memory reference bugfix from Irssi CVS tree.
5097 Affected file irssi/src/core/commands.c.
5099 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Added the server's public key sving and verification to the
5102 server when performing the SKE. This was missing and the
5103 remote server's (or router's) public key was accepted without
5104 checking whether we have it previously or trust it at all.
5105 Affected file silcd/protocol.c.
5107 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Check in the silc_server_timeout_remote if protocol is active
5110 and make sure that the protocol's final callback is called so
5111 that all memory if freed. Affected file silcd/server.c.
5113 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * silc_server_whois_send_reply crashed the server if the nickname
5116 was 127 characters long. Affected file silcd/command.c.
5118 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Added sanity check to the silc_server_new_client. If the hostname
5121 is provided inside username then check that the provided hostname
5122 really is the same as the resolved one. If the hostname was not
5123 resolved then check it from the public key. Affected file is
5124 silcd/packet_receive.c.
5126 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5127 if the server disconnected us and the connection is not valid
5128 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5130 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5131 the library to the lib/silcutil/silcutil.[ch].
5133 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Close log file after open. Affected file
5136 lib/silcutil/silclog.c.
5138 * Check whether sock == NULL in silc_client_send_packet and return
5139 if it is. Affected file lib/silcclient/silcclient.c.
5141 * Check rec->entry == NULL in the Irssi SILC Client before
5142 sending the channel message. Affecte file is
5143 irssi/src/silc/core/silc-servers.c.
5145 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Merged a splitted window bugfix from Irssi CVS tree. The
5148 affected file is irssi/src/fe-text/textbuffer-view.c.
5150 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5151 It did not print nickname.
5153 * Improved the distributions system a bit.
5155 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5158 irssi/src/fe-text/gui-window.c.
5160 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5161 to in-active server. The affected file is
5162 irssi/src/silc/core/client_ops.c.
5164 * Resolve the client in USERS command reply if the entry does
5165 not have username resolved. The affected file is
5166 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5167 command to WHOIS command to really resolve stuff. The USERS
5168 is not used any more in any critical section so WHOIS can
5169 be used even though it might be slower than IDENTIFY.
5171 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5174 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Changed the protocol API a bit more consistent in the
5177 lib/silccore/silcprotocol.[ch].
5179 * Changed the following headers to ROBODoc format:
5181 lib/silccore/silcpayload.h
5182 lib/silccore/silcprotocol.h
5183 lib/silccore/silcsockconn.h
5185 All core library headers are now formatted.
5187 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Fixed a bug in Irssi SILC client; do not show that you are
5190 server/router operator if you really are not. Affected file is
5191 irssi/src/silc/core/client_ops.c.
5193 * Renamed silc_command_free_payload to silc_command_payload_free.
5194 Affected file lib/silccore/silccommand.h
5196 * Added silcmath.h to include the prototoypes of various routines
5197 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5200 * Changed the following headers to ROBODoc format:
5202 lib/silccore/silcchannel.h
5203 lib/silccore/silccommand.h
5204 lib/silccore/silcid.h
5205 lib/silccore/silcidcache.h
5206 lib/silccore/silcmode.h
5207 lib/silccore/silcnotify.h
5208 lib/silccore/silcpacket.h
5209 lib/silcmath/silcmath.h
5211 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added checking to the server code not to start the server if
5214 ciphers and stuff are not configured properly. Affected files
5215 silcd/serverconfig.[h] and silcd/server.c.
5217 * Changed the layout of the header files of the public interfaces
5218 in the SILC libraries. The new layout supports ROBODoc
5219 documentation tool (and some others) so that it is easy to create
5220 a library reference manual. All the other headers and source
5221 code must still follow the CodingStyle document. Also source
5222 code must not include these ROBODoc stuffs, only the headers.
5223 Furthermore, all public interface headers must now be named
5224 by using `silc' prefix, example: silcapi.h, silccipher.h.
5225 Some files were renamed due to this. All the other headers
5226 must not be used as public interfaces. I will update the
5227 CodingStyle document later. Changed following headers, so far:
5229 lib/silcclient/silcapi.h

5234 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Removed silc_client_packet_send_flush from the client library
5239 as it is not needed. Affected file lib/silcclient/client.[ch].
5241 * Added printing of message of unresolved authentication method
5242 to the Irssi SILC client. Added it to the module formats.
5243 Removed the same message from the client library.
5245 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Added new distribution feature, DISTLABEL. Every distribution
5248 can define own preprocessor label that can be used in the
5249 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5250 file distributions, acconfig.h.pre and prepare.
5252 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Added Makefile.defines_int to include the actual definitions
5255 for Makefile.defines.in. Tested the new distribution system,
5256 created distributions and tested installation.
5258 * Added AWAY message printing to the Irssi SILC client. Added
5259 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5261 * Added SCONNECT command to call the SILC's CONNECT command.
5262 Cannot use CONNECT directly since Irssi uses that internally.
5263 Affected file irssi/src/silc/core/silc-servers.c.
5265 Added ACTION local command. It is same as ME command but takes
5266 the channel as mandatory argument.
5268 Rewrote some of the Irssi's help files to suite for SILC
5271 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Added Makefile.defines[.in] that should for now on be included
5274 in all Makefile.am file in the source tree. That file includes
5275 all common compilation definitions for SILC source tree.
5277 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Minor changes to the ./prepare script to change the package
5280 name according the distribution name to the configure.in.
5282 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Created new distribution system. Added file `distributions'
5285 that defines all the distributions that can be created out of
5286 the SILC source tree. The ./prepare script now reads that
5287 file to determine how to prepare the distributions. The
5288 first argument to the ./prepare is the name of the distribution
5289 and second is the version of the distribution. If given
5290 without arguments it creates the default (toolkit) distribution
5291 with the default version (defined in ./prepare).
5293 All Makefile.am files that are subject to the distributions
5294 are now named as Makefile.am.pre. These are ./Makefile.am
5295 and lib/Makefile.am. Others may be changed later.
5297 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Added invite list, ban list, some key management and connection
5300 error message printing to module formats in the Irssi SILC client.
5302 * Added new silc_client_set_away_message to set the away message
5303 that is back to the person who sent private message. The
5304 affected file lib/silcclient/silcapi.h and the
5305 lib/silcclient/client_prvmsg.c.
5307 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Fixed the private message sending in the Irssi SILC client,
5310 added local command KEY to the Irssi SILC client.
5312 Added key management and key agreement message formats to the
5313 irssi/src/fe-common/silc/module-formats.[ch].
5315 Added USERS (alias WHO) printing, server/router operator
5316 indication and LIST command printing to the module formats.
5318 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Fixed channel joining notify handling, cumode notify handling
5321 from Irssi SILC client.
5323 * Added SILC specific module-formats to the Irssi SILC client so
5324 that SILC specific message hilighting, colors etc is possible.
5325 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5327 Added channel mode, channel user mode, actions, notices,
5328 whois and whowas printing to the the module-formats.c.
5330 * Fixed a bug in channel deletion in the server. The channel
5331 is not left to the cache even if the channel founder auth mode
5332 is set when there are no users anymore on the channel. Affected
5333 file silcd/server.c.
5335 * The silc_net_localhost now resolves the entire hostname including
5336 the domain name. Affected file lib/silcutil/silcnet.c.
5338 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Changed the ask_passphrase client operation to be ascynchronous.
5341 It has now a completion callback and a context that the
5342 application must call after it has got the passphrase from
5343 the user. Affected files lib/silcclient/silcapi.h,
5344 lib/silcclient/protocol.c, lib/silcclient/command.c and
5347 Added SilcAskPassphrase callback that the application calls
5348 to deliver the passphrase to the library.
5350 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5351 The public key verification and especially a certificate
5352 verification is asynchronous procedure.
5354 Added new SILC_SKE_STATUS_PENDING status to indicate the
5355 request is pending and a callback will be called to finalize
5358 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5359 indicate that remote end did not send its public key (or
5360 certificate), even though we require it. Added check for this
5361 condition in the SKE. This was a security bug, now fixed.
5363 Defined new SilcSKEVerifyCbCompletion callback that is called
5364 when the verification process is completed.
5366 The affected files lib/silcske/silcske_status.h and
5367 lib/silcske/silcske.[ch].
5369 * Changed the verify_public_key client operation to be async
5370 as well. Defined SilcVerifyPublicKey callback that is used to
5371 indicate the success of the public key verification process.
5373 Changed the server and client to use the new async client
5376 * Changed the Irssi SILC client's internal scheduler to be called
5377 twice as many times as it used to be. As a result the client
5378 should be a bit faster now. Affected file is
5379 irssi/src/silc/core/silc-core.c.
5381 * Added support to Irssi SILC client of asynchronous public key
5382 verification and passphrase inquiry. Affected file is
5383 irssi/src/silc/core/silc-core.c.
5385 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Do not say "You have left channel %s" in client library.
5388 Moved it to the application. Affected files are
5389 lib/silcclient/command.c and silc/client_ops.c.
5391 * Fixed silc_client_get_clients. Command context was not
5392 duplicated and was freed memory in the callback. Affected
5393 file lib/silcclient/idlist.c.
5395 * Do not say "you are now talking..." on JOIN command in the
5396 client library. The appliation must handle it.
5398 * Do not say ".. changed topic to" in command reply in the
5399 client libary. The application must handle it.
5401 * Fixed TOPIC command sending in the client library.
5403 * Fixed a memory leak in silc_client_command_free in the file
5404 lib/silcclient/command.c.
5406 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Imported a modified version of Irssi client to the source tree.
5409 The Irssi will be used to create a new client called
5410 Irssi SILC. Imported to irssi/.
5412 Added silc_core_init_finish function to the Irssi. Affected
5413 file irssi/configure.in.
5415 A lot changes in the Makefile.ams around the irssi tree.
5417 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Do not rehash if the new size is same as the old size of the
5420 hash table, in the silc_hash_table_rehash*. The affected file
5421 lib/silcutil/silchashtable.c.
5423 * Replaced hash_table_del_by_context calls from the server
5424 (when channel->user_list and client->channels) to the
5425 hash_table_del as it is sufficient and faster.
5427 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Added silc_hash_table_list, silc_hash_table_get and the
5430 SilcHashTableList structure to provide an alternative way to
5431 traverse the hash table. The affected files are
5432 lib/silcutil/silchashtable.[ch].
5434 * Changed the server's idlist routines to use the hash table
5435 routines to optimize the code.
5437 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Replaced the client entry's `channel' list and channel entry's
5440 `user_list' list to hash tables for optimized lookup. Changed
5441 the code to use the hash table interface around the code.
5442 Affected file lib/silcd/idlist.[ch].
5444 * Added `auto_rehash' boolean argument to the function
5445 silc_hash_table_alloc to indicate whether the hash table should
5446 auto-rehash when it thinks is appropriate time. It will
5447 increase the hash table size if the there is twice as much
5448 entries in the table than the size of the table, and will
5449 decrease the size if there are twice as less entries than
5450 the size of the table.
5452 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5456 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * silc_idcache_purge_by_context deletes the entry now by context
5459 as it is supposed to do. Affected file lib/silccore/idcache.c.
5461 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5462 client is not anymore valid (WHOWAS givens the info) and not
5463 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5465 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Removed the `data' and `data_len' arguments from the ID Cache
5468 interfaces and added `name' argument. ID Cache does not handle
5469 anymore the binary data only a names associated with given ID.
5471 * When hashing a Client ID with silc_hash_id the entire ID is
5472 not hashed anymore, instead only the hash of the Client ID is
5473 hashed. This way we can access the Client ID from the cache
5474 with Client ID but with the hash of the ID (which is a hash of
5475 the nickname) as well without any difference in performance.
5477 Added also silc_idcache_find_by_id_one_ext to do one on one
5478 searching when we have the actual ID. Added also function
5479 silc_hash_client_id_compare. The affected files are
5480 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5482 * When hashing the name associated with a ID it is always done
5483 in lowercase. This way we can access the cache without worrying
5484 about case-sensitivity, even though, for example nicknames are
5487 * Fixed a bug in server with channel message sending. It put
5488 wrong ID type as destination ID. The affected file
5489 silcd/packet_send.c.
5491 * silc_idcache_del_by_context now deletes from all hash tables
5492 by context. Affected file lib/silccore/idcache.c.
5494 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Changed the client library to use the new ID Cache interface.
5497 Changes around the source tree.
5499 * Added silc_hash_table_rehash_ext to rehash with specific
5500 hash function. Affected file lib/silcutil/silchashtable.[ch].
5502 * Added silc_hash_string_compare to compare two strings in the
5503 hash table. Affected file lib/silcutil/silcutil.[ch].
5505 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Added new function silc_idcache_del_by_context into the
5508 lib/silccore/idcache.[ch].
5510 * Changed the server's ID list routines to use the new ID Cache
5511 interface. Changes around the source tree.
5513 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Added silc_hash_table_del[_by_context]_ext functions in to the
5516 lib/silcutil/silchashtable.[ch].
5518 Removed silc_hash_table_find_all* routines and added new
5519 silc_hash_table_find_foreach to replace them.
5521 Added silc_hash_table_replace_ext function as extended
5522 replacing function. Separated the simple hash table interface
5523 from the extended hash table interface in the file
5524 lib/silcutil/silchashtable.h.
5526 * Fixed minor bugs and changed it to use some of the new
5527 hash table functions in lib/silccore/idcache.c
5529 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Added new function silc_hash_table_find_all to return all keys
5532 in the hash table by the specified key. As the hash table is
5533 collision resistant it also makes it possible to have several
5534 duplicate keys in the hash table. This function may be used to
5535 find all of the keys from the hash.
5537 Added user_context arguments to the SilcHashFunction,
5538 SilcHashCompare and SilcHashDestructor to deliver user specified
5541 Added new fuctions silc_hash_table_find[_all]_ext to do
5542 extended lookup with specified hash and compare functions and
5543 specified user contexts.
5545 Added new function silc_hash_table_add_ext to add the key
5546 with specified hash function and user context.
5548 Added new function silc_hash_table_foreach to traverse all
5549 entrys in the hash table. Added SilcHashForeach callback
5552 Added new function silc_hash_table_del_by_context to delete
5553 the entry only if the context associated with the key matches.
5555 Affected files are lib/silcutil/silchashtable.[ch].
5557 * Removed silc_hash_[server/client/channel]_id and added just
5558 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5559 silc_hash_id_compare to compare two ID's using as the hash table
5560 comparison function. Added also silc_hash_data to hash
5561 binary data and silc_hash_data_compare to compare it.
5563 * Removed silc_idlist_find_client_by_hash as it is not needed
5564 anymore. Affected file silcd/idlist.[ch].
5566 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5567 to use internally the SilcHashTable. The new ID Cache is a lot
5568 faster than the old one. Some of the ID Cache interface was also
5569 rewritten and obsolete and stupid functions were removed.
5571 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Added entry_count field to the SilcHashTable to keep the number
5574 of the entries in the table. Implemented the function
5575 silc_hash_table_rehash. Added new function
5576 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5578 Fixed a minor bug in silc_hash_table_free.
5580 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5581 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5582 into the lib/silcutil/silcutil.[ch].
5584 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5586 * Implemented a collision resistant hash table into the
5587 lib/silcutil/silchashtable[ch]. See the header and the source
5588 for the SilcHashTable API.
5590 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Merged dotconf version 1.0.2 into lib/dotconf.
5594 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Do not compile anything in lib/silcsim/* if the SIM support
5597 is not enabled. The tree should now compile without problems
5600 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Compiled the SILC under cygwin. Compiled and tested briefly
5603 without problems. More tests needed. The SIMs didn't compile
5606 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5608 * Fixed possible crash in silc_get_username in the
5609 lib/silcutil/silcutil.c.
5611 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Fixed a va_arg in silc/client_ops.c.
5615 * Oops, RC5 routines were named AES and caused some problems
5616 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5618 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added new SilcIDIP structure into the lib/silccore/id.h and
5621 replaced the old `ip' fields from all SILC ID's to that type.
5622 This is a step towards IPv6 support.
5624 The silc_id_get_len takes now the ID as an extra argument.
5625 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5626 both IPv4 and IPv6 based ID's.
5628 The affected files are lib/silccore/id.[ch] and other files
5629 around the tree using these routines.
5631 * Removed the ID length arguments in server from various
5632 silc_server_send_notify_* routines -> they are not needed
5635 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Fixed memory leak in silc_encode_pem_file in the file
5638 lib/silcutil/silcutil.c.
5640 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Check minor version as well in the SKE. Affected files are
5643 silcd/protocol.c and lib/silcclient/protocol.c.
5645 * Added --identifier option to the server so that an identifier
5646 can be when creating the public key for the server. Affected
5647 file is silcd/silcd.c.
5649 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5650 lib/silccrypt/silcpkcs.c.
5652 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Register default ciphers and stuff when using -C option with
5655 the server. Affected file sildc/silcd.c.
5657 * Put back the servers public key filename format, it is better
5658 than the new one. For now, the client keys are saved with the
5659 new filename format. The affected file silc/client_ops.c.
5661 * Implemented the Cipher API for the rest of the ciphers that
5662 did not implement it or implemented it the wrong way.
5664 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Register default ciphers and stuff when using the -S option
5667 in the client. Affected file silc/silc.c. Same also when
5668 creating new key pair with -C option.
5670 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Fixed the silc_verify_public_key client operation function to
5673 save the public keys differently. The fingerprint is now
5674 used as filename and not the hostname. This way also the
5675 client keys are saved uniquely and not with hostnames. The
5676 affected file is silc/client_ops.c.
5678 * Trimmed the silc_hash_fingerprint function to remove extra
5679 whitespaces from the end of the fingerprint. The affected
5680 file is lib/silccrypt/silchash.c.
5684 * Added silc_cipher_register_default function to register all
5685 default ciphers. It can be used when configuration files
5686 does not exist and the application does not want any specific
5687 ciphers in any specific order.
5689 The SilcDList is now used as silc_cipher_list dynamically
5690 allocated cipher list. Removed the static list all together
5691 and now all ciphers must be allocated to the dynamic list.
5692 The silc_cipher_alloc routine was changed to check only the
5695 All silc_cipher_* routines that used to return int returns
5698 The affected files lib/silccrypt/silccrypt.[ch].
5700 * The same thing was done to silc_hash_* as for silc_cipher_*
5701 routines. Affected files lib/silccrypt/silchash.[ch].
5703 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5704 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5705 Added also silc_pkcs_[un]register[_default] functions.
5706 Removed the data_context from the PKCS API.
5708 * Added silc_hmac_register_default function to register default
5709 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5710 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5711 to unregister all hmacs at once.
5713 * Register the default ciphers, hash functions, PKCSs and HMACs
5714 if client's configuration file does not exist. The affected
5717 * The client did not load the hash functions from the SIM
5718 modules at all. Added support for this. Affected file is
5719 silc/clientconfig.c.
5721 * When decoding public key with silc_pkcs_public_key_decode, check
5722 the supported algorithm only if PKCS are registered. Affected
5723 file lib/silccrypt/silcpkcs.c. The same was done with the
5724 silc_pkcs_private_key_decode.
5726 * Fixed the SILC List routines to keep the list always in order.
5727 It used to change the list's order when traversing the list but
5728 not it preserves the order. Affected file lib/trq/silclist.h.
5730 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Added the client library to use the SilcSocketConnection's
5733 reference counter (by silc_socket_dup) to prevent the bug that
5734 the socket object may be freed underneath async operation.
5736 * The name resolv library checking fixes in the configure.in.pre.
5739 * Created new version of the protocol drafts for future
5740 development. The -03 drafts are the ones that will be changed
5741 in the trunk now and the -02 will remain as they are.
5743 * Send list of CUMODE notifys to the router when announcing
5744 the channel users to the router. Affected file silcd/server.c.
5745 If the router receiving channel founder CUMODE for a channel
5746 that already has channel founder it will send CUMODE notify
5747 to the sender to remove the channel founder rights from the
5748 announced client. Affected file silcd/packet_receive.c.
5750 * The CUMODE notify may now use Server ID as well as the entity
5751 who changes the mode. Updated protocool specs.
5753 * Updated INSTALL and README files.
5755 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * New web pages in the http://silc.pspt.fi. The pages was
5762 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Implemented the [DenyConnectin] config section in the server.
5765 Added silc_server_config_denied_conn to check whether incoming
5766 connection is denied. Affected file silcd/serverconfig.[ch].
5768 * Do not check the ports when checking the incoming configuration
5769 data if the port is 0, meaning any. Affected file is
5770 silcd/serverconfig.c.
5772 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Fixed buffer overflow in silc_string_compare in the file
5775 lib/silcutil/silcutil.c.
5777 * Fixed double free in silc_server_command_leave in the file
5780 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Fixed the version checking in the server. Affected file is
5785 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Fixed the configuration data fetching when accepting new
5788 connections in the server. Affected file silcd/server.c.
5790 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Added `sender_entry' argument to the function
5793 silc_server_packet_relay_to_channel so that we can check
5794 whether some destination actually belongs to the same route
5795 the sender belongs (ie, we must not resend the packet to the
5796 sender). Affected file silcd/packet_send.[ch].
5798 * Added `servername' field to the SilcClientEntry in the server
5799 to hold the name of the server where client is from. Affected
5800 file is silcd/idlist.h.
5802 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Moved the channel message encrypting in the router betwen
5805 router connections from silc_server_channel_message to the
5806 silc_server_packet_relay_to_channel since we want to check
5807 whether we have anybody channel before encrypting anything.
5808 Affected files silcd/packet_[receive/send].c.
5810 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Fixed the [AdminConnection] server config section to support
5813 multiple entries. Affected file silcd/serverconfig.c.
5815 * Added support into the server to check the validity of the
5816 incoming connection before executing any KE or authentication
5819 * The connection configuration is now saved to the KE and
5820 connection auth protocol contexts and not fetched anymore in
5821 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5823 * The local hosts listenning address and port is also resolved
5824 now when starting the server. We want to have the socket object
5825 to include the real address and port for the listener. Added
5826 new function silc_net_check_local_by_sock into the files
5827 lib/silcutil/silcnet.[ch].
5829 * Fixed a broadcast bug in server -> do not broadcast if we
5832 * Fixed a routing bug. Do not route broadcast packets ever.
5833 Broadcast packets must be processed always and not routed since
5834 they may be destined to some other host than yourself and thus
5835 would get routed without no good reason. Affected file is
5838 * Added function silc_server_config_is_primary_route to check
5839 whether primary router connection has been configured (a router
5840 configuration that we are initiating). If there is not, we
5841 will assume that there is only two routers in the SILC network
5842 and we will use the incoming router connection as our primary
5843 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5845 * Changed the order of the broadcasting. Broadcast _after_ the
5846 packet has been processed not before. Affected file is
5849 * Fixed a [ClientConnection] parsing bug. The port was never
5850 parsed correctly thus resulting to port 0. Affected file
5851 silcd/serverconfig.c.
5853 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5854 argument and did not set the broadcast packet flag. Affected
5855 file silcd/packet_send.c. Fixed same bug in the function
5856 silc_server_send_notify as well.
5858 * If we receive NEW_ID packet for our own ID in the server, ignore
5861 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Removed the nickname from the Private Message Payload.
5866 Updated the code and the protocol specs.
5868 * Updated protocol specs for submitting to the IETF.
5870 * Tweaked the Random Number Generator a bit. Affected file
5871 lib/silccrypt/silcrng.c. Exported a new function
5872 silc_rng_[global]_add_noise which can be used to add more
5875 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Do not parse packets with different timeout when protocol
5878 is active -> may cause problem with rekey. Affected file
5881 * When server receives signoff notify it must not create
5882 new channel key if the client is on any channels since the
5883 sender of the signoff notify will create it.
5885 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Added printing of error messages during SKE protocol from the
5888 failure packet sent by server during SKE. Affected file
5891 * Removed the client's failure_callback handling with timeout
5892 and handle it immediately when received.
5894 * The SKE library returned wrong type in SUCCESS and FAILURE
5895 packets. They must be 32 bit MSB not 16 bit MSB.
5897 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Ok, rewrote the logic of the re-key and now it seems to work.
5900 I tested it on high traffic with frequent re-keys without
5901 problems. Added hmac_receive (and renamed hmac to hmac_send)
5902 in SilcClientConnection in lib/silcclient/client.h and
5903 in SilcIDListData in silcd/idlist.h. Also, removed the
5904 SilcPacketParserContext's cipher and hmac fields as they are
5905 not needed anymore and actually caused some problems when
5906 the ciphers and hmac's changed underneath the packet parser.
5908 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * If re-key protocol is active then process the incoming packets
5911 synchronously since we must assure that icoming packets encrypted
5912 with the old key is processed before the new keys is set to
5913 use. This is true other packets than for REKEY packets.
5914 Affected file silcd/server.c. The same was done to client library
5915 as well, affected file lib/silcclient/client.c.
5917 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Fixed bug in client and server to accept the force send if
5920 the packet is send from silc_[server/client]_packet_process
5921 function. Otherwise the packets are never delivered, oops.
5923 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Disable force sending of packets when REKEY protocol is active.
5926 We must assure that no packet is sent directly when rekey is
5927 performed. All packets must be sent through packet queue.
5928 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5929 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5930 function is silc_[server/client]_packet_send_real to check
5933 * Replaced the SIM paths from example config files to
5934 /usr/local/modules. Also, make install creates now
5935 /usr/local/silc/logs directory to hold all the SILC server
5938 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Made the configure.in.pre work on Solaris. Patch by salo.
5942 * Made all ciphers compatible with non-x86 machines. Defined
5943 CBC mode macros into lib/silccrypt/ciphers_def.h.
5945 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Fixed the make install.
5949 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * When MAC computation fails the silc_packet_decrypt returned 0
5952 even though it was supposed to return -1. Fixed this. The
5953 affected file is lib/silccore/silcpacket.c.
5955 * Do not replace the config files in /etc/silc (in make install)
5956 if they already exist. Affected file ./Makefile.am.
5958 * Do not send re-key packets immediately but through packet queue.
5959 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5961 * Changed silc_net_check_host_by_sock to return FALSE if the
5962 IP/DNS could not be resolved. Though, it returns the IP address
5963 now even if it could not resolve it (but returns also FALSE).
5964 Affected file lib/silcutil/silcnet.[ch].
5966 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Added silc_pkcs_decode_identifier to decode the public key's
5969 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5970 Added also silc_pkcs_free_identifier. Added also new context
5971 SilcPublicKeyIdentifier.
5973 * Added -S option to the silc client. It is used to dump the
5974 contents of the specified public key file.
5976 * Changed the PKCS api to return the public key length when
5977 setting the public key.
5979 * Fixed a fatal bug in the public and private key file loading.
5980 Affected file lib/silccrypt/silcpkcs.c.
5982 * Execute the packet parsing for client with zero (0) timeout
5983 if the protocol is active. Affected file silcd/server.c.
5985 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5987 * Made the key generation options to the silcd program. Added
5988 -C option, equivalent to client's option.
5990 * Added new [ServerKeys] config section to the server. It
5991 configures the server's public and private key.
5993 * Defined generic Public Key Payload into the protocol
5994 specification to send specific type of public keys and
5997 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5998 public key or certificate.
6000 * Implemented the GETKEY command to the server and to the
6001 client library and on user interface.
6003 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Made preliminary `make install' work.
6007 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6009 * Added SilcServerRekey context into silcd/idlist.h.
6011 * Added the PFS support as defined in the specification to the
6012 SKE protocol. Affected files lib/silcske/*.c.
6014 * Added `ske_group' field to the SilcServerRekey context to hold
6015 the number of the SKE group that is used with PFS in re-key.
6016 Affected file silcd/idlist.h.
6018 * Added PFS re-key support to the server. Affected file is
6021 * Added silc_protocol_cancel to cancel execution of the next
6022 state of the protocol. Affected file is
6023 lib/silccore/silcprotocol.[ch].
6025 * Added the re-key support with and without PFS to the client
6026 library. Re-key is performed once in an hour, by default.
6028 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6029 Added silc_client_rekey_callback and silc_client_rekey_final.
6030 Affected files are lib/silcclient/protocol.[ch] and
6031 lib/silcclient/client.[ch].
6033 * Removed the `hmac_key' and `hmac_key_len' fields from the
6034 SilcClientConnection structure; not needed. Affected file is
6035 lib/silcclient/client.h.
6039 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Do not ask whether user wants to use the negotiated private key
6042 for private messages, just use it. Affected file is
6043 silc/local_command.c.
6045 * Added `send_enc_key' and `enc_key_len' fields to the
6046 SilcIDListData structure since they are needed in the re-key
6047 phase. Affected file is silcd/idlist.[ch].
6049 * Implemented the simple re-key protocol into the server.
6050 Affected files silcd/server.c and silcd/protocol.[ch]. The
6051 re-key will be performed once in an hour, by default.
6053 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6054 Added silc_server_rekey, silc_server_rekey_callback and
6055 silc_server_rekey_final.
6057 * Removed Tunneled flag from the protocol. Updated the code
6058 and the specifications.
6060 * Adde `pfs' field to the SilcIDListData to indicate whether
6061 the PFS is to be performed in the re-key. Affected file is
6064 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6067 int64 of at least the xintXX size. If void * is less that 4
6068 bytes uint32 * will be used. Defined bool as boolean.
6070 * Changed _ALL_ unsigned long and unsigned int to uint32,
6071 unsgined short to uint16 in the source tree.
6073 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6074 not handle clients that has entry->data.registered == FALSE.
6075 They are not in the network anymore. Affected file is
6078 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Implemented the sending of the SERVER_SIGNOFF notify in the
6081 server. Affected file is silcd/server.c.
6083 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6084 Added also silc_notify_payload_encode_args into the
6085 lib/silccore/silcnotify.[ch].
6087 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6088 Affected file silcd/packet_receive.c.
6090 * Implemented the SERVER_SIGNOFF notify handling in the client
6091 library. Affected file lib/silcclient/client_notify.c. Also,
6092 implemnted the printing of the SERVER_SIGNOFF info to the
6093 application. Affected file silc/client_ops.c.
6095 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6096 if the deleting was successful. Affected file silcd/idlist.[ch].
6098 * Added support for public key authentication in the connection
6099 authentication protocol in the client library. Affected file
6100 lib/silcclient/protocol.c.
6102 * Changed the server's silc_idlist_get_clients_by_* interface
6103 to support already allocated array so that new entries may be
6104 added to pre-allocated array. Affected file silcd/idlist.[ch].
6105 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6106 and command replies.
6108 * All command reply functions in the server now calls the
6109 pending command callback even if error occured. This way the
6110 error will be delivered to the client as well. Affected files
6111 silcd/command.c and silcd/command_reply.c.
6113 * Fixed INFO command to return local server's info if no server
6114 was provided. Affected file lib/silcclient/command.c.
6116 * Removed RESTART command for good. Updated the code and the
6119 * Rewrote parts of the task system. It is a bit simpler now.
6120 Removed unsued task priorities. The affected files are
6121 lib/silcutil/silctask.[ch].
6123 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Moved the USERS printing from the library to the application.
6126 Affected files lib/silcclient/command.c and silc/client_ops.c.
6128 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Added channel key re-key support. The re-key is perfomed
6133 only by the router and is done once in an hour. Added `rekey'
6134 field to the SilcChannelEntry in the server. Affected files
6135 silcd/server.c and silcd/idlist.h.
6137 * Added silc_task_unregister_by_context into the file
6138 lib/silcutil/silctask.[ch].
6140 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Added SILC_UMODE_GONE mode to indicate when the client is not
6143 present in the SILC network. Added also support to the local
6144 command AWAY that will set this mode. Added support of showing
6145 "xxx is gone" in WHOIS command. The USERS command shows the
6146 gone status as well.
6148 * Fixed setting server and router operator privileges in the
6149 server's UMODE command. Affected file silcd/command.c.
6151 * Merged the SKE KE1 and KE2 payloads into one payload. The
6152 new KE payload is equivalent to the old KE2 payload.
6154 Cleaned up the SKE Start Payload parsing. It now uses the
6155 simple buffer unformatting to do the parsing. A lot faster
6158 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6159 to the SKE that is used to indicate whether both of the SKE
6160 parties should perform authentication. By default only the
6161 responder performs authentication. By setting this flag also
6162 the initiator must do authentication. By default it is unset
6163 since in normal SKE case, client to server connection, only
6164 the responder should do authentication. When doing SKE between
6165 two clients both should perform authentication. Updated the
6166 code and the protocol specs.
6168 * A little fix to IDENTIFY command in the server. Search the
6169 client first by hash not nickname. Affected file is
6172 * Fixed the silc_client_close_connection to support closing
6173 the client to client connections wihtout deleting too much
6174 data. Affected file lib/silcclient/client.c.
6176 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6177 are received if protocol used to be active but is not anymore
6178 the application would crash due to NULL pointer dereference.
6179 Affected files silcd/server.c and lib/silcclient/client.c.
6181 * Added `hash' field to the SilcClientConnection to include
6182 the hash function negotiated in the SKE protocol.
6184 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6185 to set the channel founder authentication data. A client can
6186 claim the founder rights later by providing the authentication
6187 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6188 This way the channel founder can regain the channel founder
6189 privileges even it is left the channel. This works only on
6190 local server and the client must be connected to the same
6191 server to be able to regain the founder rights. Updated the
6192 protocol specs accordingly.
6194 Added support to the CMODE command in the client to set the
6195 founder auth data. Read the README to see how to set it.
6197 Added support to the CUMODE command to claim the founder
6198 rights. Read the README to see how to do it.
6200 Added support for the founder authentication to the Channel
6201 Entry in the server. Affected file silcd/idlist.h.
6203 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6204 server's CMODE command. Affected file silcd/command.c.
6206 * Added the following new functions into lib/silccore/silcauth.[ch]:
6207 silc_auth_get_method and silc_auth_get_data.
6209 * The server now saves the remote hosts public key to the
6210 SilcIDListData pointer. Affected file silcd/protocol.c.
6212 * The normal server now does not remove the channel entry from
6213 the cache if the founder authentication data is set. It used
6214 to remove it if the founder was the last one on the channel on
6215 the server and left the channel. The auth data is saved and
6216 if the channel is re-joined later the old entry is used with
6217 the old auth data. Affected files silcd/command_reply.c and
6220 * Removed the `pkcs' field from the SilcIDListData structure
6221 in the server; it is not used. Affected file silcd/idlist.h.
6223 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Fixed packet processing on slow links. Partial packets were
6226 never re-processed because the incoming data buffer was cleared
6227 by the application. Application must not directly clear the
6228 sock->inbuf, the packet processing routines handle it. Fixed
6229 this in client library and in server.
6231 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Fixed the WHOIS and IDENTIFY send reply function to really
6234 check whether to send list or just one entry. Affected file
6237 * Cleaned up the LEAVE command's channel key distribution. The
6238 affected file silcd/command.c.
6240 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6241 can enforce the channel mode as well. In that case the ID
6242 includes the ID of the server. The code now enforces the
6243 mode change if the router have different mode than the server.
6245 * The notify client operation with CMODE_CHANGE notify can now
6246 return NULL client_entry pointer if the CMODE was not changed
6247 by client. Application must check for this.
6249 * Added <Server ID> argument to INFO command to support server
6250 info fetching by Server ID.
6252 * Added silc_server_announce_get_channel_users to get assembled
6253 packets of channel users of the specified channel. Affected
6254 file silcd/server.[ch].
6256 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6257 was freed underneath the ID Cache.
6259 * Re-announce clients when the server received CHANNEL_CHANGE
6260 notify from the router. Affected file silcd/packet_send.c.
6262 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6264 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6265 crashed since it did not handle the fact that there is no cipher
6266 called "3" and didn't check the error condition. Now fixed.
6268 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6269 flag. It can be used to send message requests.
6271 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Implemented the RESTART command in the client.
6275 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6276 notice type messages. Added notice printing to the user
6279 * The channel keys are not re-generated if the channel's mode
6280 is PRIVKEY, ie private key on the channel exists. Affected
6281 files silcd/server.c and silcd/command.c.
6283 * Fixed a little bug in channel message delivery when channel
6284 private keys are set in the server. Affected file is
6285 silcd/packet_send.c.
6287 * Changed the setting on channel->on_channel = TRUE from the
6288 silc_client_save_channel_key to the JOIN command reply. The
6289 key payload is not received if the private channel key is set.
6290 Affected file lib/silcclient/command_reply.c and the
6291 lib/silcclient/client_channel.c.
6293 * When the CMODE_CHANGE notify is sent and the channel private
6294 key mode is removed the channel key must be re-generated in
6295 other cells as well. Added this support for the router in the
6296 silcd/packet_receive.c.
6298 * Added new local command NOTICE to send notice message on
6299 channel. Affected file silc/local_command.[ch].
6301 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Added new local command ME to the client. It is used to send
6304 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6305 some action. Affected file silc/local_command.[ch].
6307 * Changed channel_message and private_message client operations
6308 to deliver the message flags to the application. Added also
6309 the `flags' arguments to the silc_client_send_channel_message
6310 and silc_client_send_private_message functions. Affected file
6313 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Redefined the Private Message Payload to support private message
6316 keys and to support the new private message flags. Updated
6317 the protocol specs. Flags makes it possible to have for example
6318 CTCP style messages.
6320 * Added new type SilcPrivateMessagePayload and defined an API
6321 for it in the lib/silcclient/silcprivate.[ch].
6323 * Tested private message private keys successfully. Tested the
6324 private message key set, unset and list commands with the new
6327 * Redefined the Channel Message Payload to include the channel
6328 message flags (equal with private message flags) to support
6329 for example CTCP style messages.
6331 * Defined some of the message (for channel and private message)
6332 flags. Updated the protocol specs and added the flags to the
6333 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6335 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Added SilcKeyAgreementStatus type to the key agreement routines
6338 to indicate the current status and error if one occured.
6339 The status types are defined in the lib/silcclient/silcapi.h.
6341 * Added new local command KEY that is used to set and unset private
6342 keys for channels, set and unset private keys for private messages
6343 with remote clients and to send key agreement requests and
6344 negotiate the key agreement protocol with remote client. The
6345 key agreement is supported only to negotiate private message keys,
6346 it currently cannot be used to negotiate private keys for channels,
6347 as it is not convenient for that purpose.
6349 * Fixed a minor pending callback setting bug in the function
6350 silc_client_get_client_by_id_resolve, now the function works.
6351 Affected file lib/silcclient/idlist.c.
6353 * Added function silc_net_get_local_port to get local bound
6354 port by socket. Added to lib/silcutil/silcnet.[ch].
6356 * Added `sockets' and `sockets_count' fields to the SilcClient
6357 object. They hold the sockets of the listenning sockets in
6358 the client. Listenning sockets may be for example the key
6359 agreement server. Affected file lib/silcclient/client.[ch].
6360 Added functions the silc_client_add_socket and the
6361 silc_client_del_socket. They are exported to the application
6364 * Added ~./silc/clientkeys to support other client's public keys.
6366 * Renamed verify_server_key client operation to verify_public_key
6367 and added one argument to indicate the type of the connection
6368 (server, client etc.).
6370 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added silc_server_connection_auth_request to handle the
6373 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6374 silcd/packet_receive.[ch].
6376 * Added silc_server_send_connection_auth_request into the
6377 silcd/packet_send.c to send the connection auth request packet.
6379 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6382 * Fixed the public key authentication in responder side in the
6383 server. The `auth_data' pointer includes the SilcPublicKey
6384 not the path to the public key. Affected file silcd/protocol.c.
6386 * Implemented the public key authentication in the initiator side
6387 in the server. Affected file silcd/protocol.c.
6389 * Removed the [RedirectClient] config section from the server
6390 configuration. Is not needed and I don't want to implement it.
6392 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Cleaned up the CMODE command in the server. It now works
6395 correctly and supports all the modes defined in the protocol.
6396 Affected file is silcd/command.c.
6398 * Added `hmac_name' field to the SilcChannelEntry in the server
6399 to hold the default HMAC of the channel. It can be set when
6400 creating the channel (with JOIN command). Affected files
6403 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6404 type to indicate the change of the current cipher and hmac
6405 on the channel. Client can safely ignore the <cipher> argument
6406 (if it chooses to do so) since the CHANNEL_KEY packet will
6407 force the channel key change anyway. The <hmac> argument is
6408 important since the client is responsible of setting the new
6409 HMAC and the hmac key into use.
6411 * Fixed the CMODE command in the client library as well.
6413 * Tested CMODE command in router environment successfully.
6415 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6417 * Show the version of the remote client (or server) when connecting
6418 to the server. It is logged to the log file. Affected file
6419 is silcd/protocol.c.
6421 * Fixed the KILLED notify handling in the client library. The
6422 client must be removed from all channels when receiving the
6425 Also, do not remove the client entry when giving the KILL
6426 command but when the KILLED notify is received.
6428 * Removed silc_idlist_find_client_by_nickname from the server.
6429 Not needed anymore. Affected files silcd/idlist.[ch].
6431 * Implemented the CHANNEL_CHANGE notify type handling to the
6432 server. Affected file silcd/server.c.
6436 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Added silc_server_send_notify_invite to send the INVITE
6439 notify between routers.
6441 * Implemented the INVITE command correctly to the server.
6443 * Implemented the INVITE notify type handling in the server.
6445 * Implemented the INVITE command to the client library and on the
6448 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Added function silc_server_get_client_resolve to find the
6451 client entry by ID from all ID lists and then resolve it
6452 (using WHOIS) if it cannot be found. Affected file is
6455 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * Implemented the BAN command to the client library.
6459 * The JOIN command in the server now checks the invite list
6462 * Changed the silc_command_reply_payload_encode_va and the
6463 silc_command_payload_encode_va to support that if argument is
6464 NULL it ignores and checks the next argument. Affected file
6465 lib/silccore/silccommand.c.
6467 * Added silc_server_send_notify_ban to send the BAN notify
6468 type between routers.
6470 * Chaned the silc_notify_payload_encode to support that if
6471 argument is NULL it ignores and checks the next argument.
6472 Affected file lib/silccore/silcnotify.c.
6474 * Tested ban lists in router environment successfully.
6476 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Implemented BAN command to the server, in silcd/command.[ch].
6480 * Removed the BAN and INVITE_LIST modes from the CMODE command
6483 * Added function silc_string_match to regex match two strings.
6484 Affected files lib/silcutil/silcutil.[ch].
6486 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Redefined parts of the SilcChannelEntry in the server to support
6489 the new ban and invite lists.
6491 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Redefined the INVITE command. The same command can be used to
6494 invite individuals to the channel but also to manage the invite
6495 list of the channel (to add to and remove from the invite list).
6496 Updated the protocol specs.
6498 * Added new command SILC_COMMAND_BAN that can be used to manage
6499 the ban list of the channel. Updated the protocol specs.
6501 * Removed the channel modes: the SILC_CMODE_BAN and the
6502 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6503 in the CMODE command. The equivalent features are now available
6504 using INVITE and BAN commands. Updated the protocol specs.
6506 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6507 in the network about change in the current ban list. The notify
6508 type is not used by the client.
6510 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6511 support the invite lists.
6513 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6515 * Added new function silc_string_regexify that converts string
6516 including wildcard characters into regex string that can
6517 be used by the GNU regex library. Added into the file
6518 lib/silcutil/silcutil.[ch].
6520 Added silc_string_regex_combine to combine to regex strings
6521 into one so that they can be used as one regex string by
6522 the GNU regex library. Added into the file
6523 lib/silcutil/silcutil.[ch].
6525 Added silc_string_regex_match to match two strings. It returns
6526 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6528 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Imported GNU regex to the soruce tree into lib/contrib.
6531 Fixed some compiler warning from the regex.c.
6533 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Fixed MOTD command in the server to work in router environment.
6537 * Fixed the MOTD command in the client library to support
6538 the server argument in the command.
6540 * Added `nickname_len' argument to the silc_idlist_add_client
6541 in the server, as the `nickname' argument may be binary data
6544 * Added silc_idlist_get_channels to return all channels from
6547 * Implemented LIST command to the server. Affected file is
6550 * Implemented the LIST command to the client library and on the
6553 * Added [<user count>] argument to the LIST command reply.
6554 With private channels the user count is not shown.
6556 * Updated TODO and README.
6558 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6560 * The client entry's data.registered must be TRUE even with
6561 global client entry on global client list. The data.registered
6562 is used to check whether the client is anymore in the network,
6563 for example with WHOWAS command so it must be valid.
6565 * Fixed the WHOWAS command in the server. It now actually works
6566 in router environment. Added function into silcd/command_reply.c
6567 silc_server_command_reply_whowas_save.
6569 * Added silc_idlist_purge function to the silcd/idlist.c
6570 to periodically purge the ID Cache.
6572 * Fixed INFO command in the server. It works now in router
6573 environment. Added <server name> argument to the INFO command
6574 reply. Updated the protocol specs.
6576 * Fixed minor bug in silc_idcache_purge to not purge if the
6577 expire value is zero.
6579 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6580 they were buggy because of the WHOWAS information.
6582 * Fixed local command MSG to handle the async resolving of
6583 the remote client properly. It used to fail the first MSG.
6584 Affected file silc/local_command.c.
6586 * Added `data_len' field to SilcIDCache context.
6588 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Update TODO. Todo in commands in the server.
6592 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6595 used by routers as broadcast packet to inform other routers
6596 about the changed user mode.
6598 Implemented the notify handling in the server. Affected file is
6599 silcd/packet_receive.c. Added the function
6600 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6602 * Added new generic Channel Payload and deprecated the New Channel
6603 Payload. The New Channel Payload is now the generic Channel
6606 * Added new argument `mode' to the silc_server_send_new_channel
6607 as it is required in the Channel Payload now.
6609 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6610 and created a new and real SilChannelPayload to represent the
6611 new generic Channel Payload. Implemented the encode/decode
6612 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6614 * Added silc_server_get_client_channel_list to return the list
6615 of channels the client has joined for WHOIS command reply.
6616 Affected file silcd/server.[ch].
6618 * Implemented the channel list sending in the WHOIS command reply
6619 in server and in the client.
6621 Implemented the channel list displaying on the user interface
6622 as well. Affected file silc/client_ops.c.
6624 * Added silc_channel_payload_parse_list to parse list of Channel
6625 Payloads. It returns SilcDList list of SilcChannelPayloads.
6626 Client for example can use this function to parse the list of
6627 channels it receives in the WHOIS command reply. The caller
6628 must free the list by calling silc_channel_payload_list_free.
6629 Affected files lib/silccore/silcchannel.[ch].
6631 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Added one new argument <user mode> to the WHOIS command reply
6634 to return the mode of the user in SILC. Updated the protocol
6637 Implemented it to the server and client.
6639 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Fixed the mode printing on the user interface on joining.
6642 Affected file silc/client_ops.c.
6644 * Implemented the UMODE command and user modes in general to the
6645 client library and to the user interface.
6647 * Implemented the UMODE command to the server.
6649 * The server now sends UNKNOWN_COMMAND error status if client sends
6650 unknown command. Affected file silcd/command.c.
6652 * All server commands now handle the command identifier the right
6653 way when sending the command reply to the client. The client can
6654 use to identify the command replies with the identifier.
6656 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Added silc_server_get_client_route to resolve the route to
6659 the client indicated by the client ID. Affected file is
6662 * Added silc_server_relay_packet as general function to relay
6663 packet to arbitrary destination. This deprecates functions
6664 like _send_private_message_key, _relay_notify etc. Affected
6665 file is silcd/packet_send.[ch].
6667 Removed silc_server_send_key_agreement,
6668 silc_server_send_private_message_key and
6669 silc_server_packet_relay_notify functions from the file
6670 silcd/packet_send.[ch].
6674 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6675 server. Affected file silcd/packet_receive.[ch].
6677 * Implemented the KILL command to the client. Implemented the
6678 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6679 Affected files lib/silcclient/command[_reply].c and
6680 lib/silcclient/client_notify.c. Implemented the KILL notify
6681 printing in the user inteface.
6683 * Fixed a lot silc_parse_nick memory leaks from the client
6684 library in the file lib/silcclient/command.c.
6686 * Changed the silc_server_send_notify_on_channels's `sender'
6687 argument from SilcSocketConnection to SilcClientEntry to
6688 check the sender as entry and not as connection object and not
6689 to send to the client provided as argument. The affected file
6690 is silcd/packet_send.[ch].
6692 * The notify packets that are destined directly to the client used
6693 to not to be processed by the server. Now changed that and the
6694 server processes all notify packets. After relaying the packet
6695 to the client the notify packet is processed in the server.
6697 * The silc_server_free_client_data now checks whether there is
6698 pending outgoing traffic for the client and purges the data to
6699 the network before removing the client entry.
6701 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6704 an client is killed from the SILC Network. Updated the protocol
6707 Added new function silc_server_send_notify_killed to the
6708 silcd/packet_send.[ch].
6710 * Added function silc_server_packet_relay_notify to relay notify
6711 packets that are destined directly to a client. In this case
6712 the server does not process the notify packets but merely relays
6713 it to the client. Affected file silcd/packet_send.[ch].
6715 Added also silc_server_packet_process_relay_notify to check
6716 whereto relay the notify. Affected file is
6717 silcd/packet_receive.[ch].
6719 * Implemented the KILL command to the server.
6723 * Added the backup schema desgined last fall to the protocol
6724 specs for everyone to see. The specification is in the
6725 *-spec-xx.txt draft and the packet type definitions for the
6726 backup routers is in *-pp-xx.txt draft. Thusly, added also
6727 new packet type SILC_PACKET_CELL_ROUTERS.
6729 * A big security problem in the implementation discovered. The
6730 signoff of an client did not cause new channel key generation
6731 which it of course should've done. The channel keys must be
6732 always re-generated when client leaves (or signoffs) the channel.
6733 The silc_server_remove_from_channels funtion now handles
6734 the channel key re-generation.
6736 * Added `sender' argument to the silc_server_send_notify_on_channels
6737 to not to send the client provided as argument. Affected file
6738 silcd/packet_send.[ch].
6740 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Implemented OPER and SILCOPER commands into the server and
6745 * Added silc_auth_verify and silc_auth_verify_data to verify
6746 the authentication directly from the authentication payload.
6747 It supports verifying both passphrase and public key based
6748 authentication. Affected file lib/silccore/silcauth.[ch].
6750 * Added `hash' field to the SilcIDListData structure. It is the
6751 hash negotiated in the SKE protocol. Affected file is
6754 * Slight redesigning of the SilcAuthPayload handling routines.
6755 Do not send SilcPKCS but SilcPublicKey as argument.
6757 * Implemented the public key authentication support to the
6758 serverconfig. The public key is loaded from the provided path
6759 and saved as authentication data to void * pointer. Thus,
6760 changed the unsigned char *auth_data to void *auth_data;
6762 * Fixed SHUTDOWN command to send the reply before the server
6763 is shutdown. :) Affected file silcd/command.c.
6765 * Fixed fatal bug in CONNECT command. The hostname was invalid
6766 memory and server crashed. Affected file silcd/command.c.
6768 * Fixed fatal bug in CLOSE command. The server_entry became
6769 invalid but was referenced later in the command. Affected file
6772 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Fixed fatal bug in failure packet handling. Server ignored
6775 the failure and thus crashed when it came.
6779 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6782 that the command may be executed only once in (about) 2 seconds.
6783 The old SILC_CF_LAG flag is same but allows command bursts up
6784 to five before limiting.
6786 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6787 server code. Various commands now includes the CF_LAG_STRICT
6788 flag to disallow any kind of miss-use of the command.
6790 * Fixed the silc_buffer_unformat to not to allocate any data
6791 if the length of the data is zero. It used to allocate the
6792 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6794 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Changed the format of AdminConnection configuration section
6797 in the server. Added username of the admin to the format.
6798 Affected files silcd/serverconfig.[ch].
6800 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6801 to return admin configuration data by host, username and/or
6804 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Implemented WHOWAS command to the server. Added the functions:
6808 silc_server_command_whowas_parse,
6809 silc_server_command_whowas_send_reply,
6810 silc_server_command_whowas_from_client and
6811 silc_server_command_whowas_from_server
6813 * Added <Client ID> argument to the WHOWAS command reply. Updated
6814 the protocol specs accordingly.
6816 * Implemented WHOWAS command and command_reply to the client
6819 Implemented the WHOWAS printing on the user interface.
6821 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6823 * Added new argument to the WHOWAS command reply, the real name.
6824 It is an optional argument. Updated the protocol specs.
6826 * Added SilcIDCacheDestructor callback that is registered when
6827 the SilcIDCache is allocated. The callback is called when
6828 an cache entry in the ID Cache expires, or is purged from the
6829 cache. Added into lib/silccore/idcache.[ch].
6831 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6832 to destruct the client entries when the cache entry expires.
6833 Other ID Cache's in server and in the client library ignores
6836 * If the ID Cache entry's `expire' field is zero then the entry
6837 never expires. Added boolean `expire' argument to the
6838 silc_idcache_add function in the lib/silccore/idcache.[ch].
6839 If it is TRUE the default expiry value is used.
6841 * Added silc_server_free_client_data_timeout that is registered
6842 when client disconnects. By default for 5 minutes we preserve
6843 the client entry for history - for WHOWAS command.
6845 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Added support to the server to enforce that commands are not
6848 executed more than once in 2 seconds. If server receives
6849 commands from client more frequently, timeout is registered
6850 to process the commands. Affected file silcd/command.c.
6851 Added new function silc_server_command_process_timeout.
6853 * Changed NICK_NOTIFY handling in client library to check that
6854 if the client's nickname was changed, so there is no need to
6855 resolve anything from the server.
6857 * Removed error printing from the WHOIS and IDENTIFY commands.
6858 If error occurs then it is ignored silently in the client library.
6859 The application, however, may map the received error to
6860 human readable error string. The application currently maps
6861 the NO_SUCH_NICKNAME error to string.
6863 * Made the command status message public to the application. Moved
6864 them from lib/silcclient/command_reply.c to
6865 lib/silcclient/command_reply.h. The application can map the
6866 received command status to the string with the
6867 silc_client_command_status_message function.
6869 * Added check to the server to check that client's ID is same
6870 as the Source ID in the packet the client sent. They must
6873 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Added dist-bzip hook to the Makefile.am to make bzip2
6876 compressed distributions.
6878 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Server now enforces the maximum length for the nickname and
6881 the channel as protocol specification dictates. 128 bytes for
6882 nickname and 256 bytes for channel name.
6884 * Moved the WHOIS printing to the application. The client libary
6885 does not print out the WHOIS information anymore, the application
6886 must do it. Renamed silc_client_command_reply_whois_print to
6887 the silc_client_command_reply_whois_save.
6889 The client's idle time is also sent to the application now, and
6890 the idle is shown on screen.
6892 * Added silc_client_command_reply_identify_save to save the
6893 received IDENTIFY entries.
6895 * Do not check for channel private keys in message sending and
6896 reception if the channel does not have the PRIVKEY mode set.
6897 Affected file lib/silclient/client_channel.c.
6899 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6902 just surfaced after chaning the JOIN procedure.
6904 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * Added silc_client_get_clients_by_list to get client entries
6907 from Client ID list, that is returned for example by JOIN
6908 and USERS command replies. The application should use this
6909 function for example when JOIN command reply is received to
6910 resolve the clients already on the channel (library does not
6911 do that anymore as USERS command reply is not used in the JOIN
6912 procedure anymore). Affected files lib/silcclient/silcapi.h and
6913 lib/silcclient/idlist.c.
6915 * JOIN command reply and USERS command reply returns now SilcBuffer
6916 pointers instead of unsigned char pointers when returning
6917 the client list and mode list.
6919 * Added <Client ID> argument to the JOIN command reply, mainly
6920 for the server to identify for which client the command was
6921 originally sent. Updated protocol specs accordingly.
6923 * Added SilcDlist private_key pointer to the SilcChannelEntry
6924 in the client to support the channel private keys. Affected
6925 file is lib/silcclient/idlist.h.
6927 * Added SilcChannelPrivateKey argument to the function
6928 silc_client_send_channel_message so that application can choose
6929 to use specific private ke if it wants to. If it is not provided,
6930 the normal channel key is used, unless private keys are set.
6931 In this case the first (key that was added first) is used
6932 as the encryption key.
6934 * Implemented the support for channel private key handling.
6935 Implemented the following functions:
6937 silc_client_add_channel_private_key,
6938 silc_client_del_channel_private_keys,
6939 silc_client_del_channel_private_key,
6940 silc_client_list_channel_private_keys and
6941 silc_client_free_channel_private_keys
6943 Affected file lib/silcclient/client_channel.c.
6945 * Added the support for the private keys in the channel message
6946 sending and encryption and in the message reception and
6947 decryption. Affected funtions are
6948 silc_client_send_channel_message and silc_client_channel_message.
6950 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Added SKE's key verify callback to the client library's
6953 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6955 * Removed the statement that server (or router) must send USERS
6956 command reply when joining to the channel so that the client
6957 knows who are on the channel. Instead, the client list and
6958 client's mode list is now sent in the JOIN command reply to the
6959 client who joined channel. This is better solution.
6961 * Added function silc_server_get_users_on_channel and function
6962 silc_server_save_users_on_channel to the silcd/server.[ch].
6964 * Removed function silc_server_command_send_users from the
6967 * Do not show topic on the client library anymore. The topic is
6968 sent in the command reply notify to the application and the
6969 application must show the topic now.
6971 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added client searching by nickname hash into the IDENTIFY and
6974 WHOIS commands in the server as they were clearly missing from
6975 them. Affected file is silcd/command.c.
6977 * Fixed a bug in private message receiving in the client library.
6978 The remote ID was freed and it wasn't supposed, now it is
6981 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6983 * Minor fix to the channel payload; allocate the data area, as it
6984 needs to be of specific length.
6986 * If the key agreement port is zero then the operating
6987 system will define the bound port. Affected files are
6988 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6990 * Added new function silc_channel_payload_decrypt into the file
6991 lib/silccore/silcchannel.[ch].
6993 * Moved the channel message etc, check from silc_packet_decrypt
6994 to applications. The library calls now a generic
6995 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6996 when the packet is either normal or special. This was done to
6997 allow more wide range of checking that was not allowed when
6998 the code was in library. Now applications can do virtually any
6999 checks to the packet and return to the library the decision how
7000 the packet should be processed. Affected files are
7001 lib/silccore/silcpacket.[ch].
7003 Added silc_server_packet_decrypt_check to the server and
7004 silc_client_packet_decrypt_check to the client library.
7006 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7007 to send with specified source and destination information.
7009 * Channel message delivery between routers was broken after the
7010 channel key distribution was fixed earlier. The channel key
7011 was used be to distributed to other routers as well which is not
7012 allowed by the protocol. Now this is fixed and channel keys
7013 really are cell specific and the channel message delivery between
7014 routers comply with the protocol specification.
7016 * Fixed various commands in server to check also the global list
7017 for the channel entry and not just the local list. The affected
7018 file silcd/command.c.
7020 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Added assert()s to buffer formatting and unformatting routines
7023 to assert (if --enable-debug) when error occurs. Affected
7024 file: lib/silcutil/silcbuffmt.c.
7026 * Changed to auto-reconnect to check whether the remote host is
7027 router and register the re-connect timeout if it is. It used
7028 to check that whether we are normal server, but router must do
7029 auto-reconnect with another router as well. Affected file
7032 * Removed the [<key len>] option from CMODE command as the cipher
7033 name decides the key length, nowadays. See the defined ciphers
7034 from the protocol specification.
7036 * Added [<hmac>] option to the CMODE command to define the HMAC
7037 for the channel. Added SILC_CMODE_HMAC channel mode.
7039 * Added [<hmac>] option for the JOIN command so that user can
7040 select which HMAC is used to compute the MACs of the channel
7043 * Added Hmac field to the Channel Message Payload. The integrity
7044 of plaintext channel messages are now protected by computing
7045 MAC of the message and attaching the MAC to the payload. The
7046 MAC is encrypted. Now, it is clear that this causes some
7047 overhead to the size of the packet but rationale for this is that
7048 now the receiver can verify whether the channel message decrypted
7049 correctly and also when private keys are set for the channel the
7050 receiver can decrypt the packet with several keys and check from
7051 the MAC which key decrypted the message correctly.
7053 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7054 lib/silccrypt/silccipher.[ch].
7056 * Added silc_hash_len to return the digest length into the
7057 lib/silcrypt/silchash.[ch].
7059 * Rewrote parts of Silc Channel Payload interface in the
7060 lib/silccore/silcchannel.[ch]. The encode function now also
7061 encrypts the packet and parse function decrypts it.
7063 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Fixed a minor formatting bug in the SKE's key material processing.
7066 It actually might have processed the keys wrong way resulting
7069 * Redefined the mandatory HMAC algorithms and added new algorithms.
7070 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7071 and hmac-md5 truncated to 96 bits. The mandatory is now
7072 hmac-sha1-96. Rest are optional (including the one that used
7073 to be mandatory). Rationale for this is that the truncated HMAC
7074 length is sufficient from security point of view and can actually
7075 make the attack against the HMAC harder. Also, the truncated
7076 HMAC causes less overhead to the packets. See the RFC2104 for
7079 * Added new [hmac] configuration section. The SKE used to use
7080 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7081 is of course wrong. The official names that must be proposed in
7082 the SKE are the ones defined in the protocol specification
7083 (hmac-sha1-96 for example). The user can configure any hmac
7084 using any hash function configured in the [hash] section. At
7085 least, the mandatory must be configured.
7087 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7089 * Added HMAC list to the SKE proposal list. It has now both
7090 hash algorithm list and HMAC list. This makes the protocol
7091 incompatible with previous versions. The SKE now seems to work
7092 the way it is supposed to work, for the first time actually.
7094 * Defined plain Hash algorithms to the protocol specification.
7097 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Implemented support for key agreement packets into the server.
7100 Added functions silc_server_key_agreement and
7101 silc_server_send_key_agreement. Other than these functions,
7102 server has nothing to do with this packet.
7104 * Added support for private message key packets into the server.
7105 Added functions silc_server_private_message_key and
7106 silc_server_send_private_message_key.
7110 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7111 called in the protocol's final callback instead in the END
7112 protocol state. This makes a little more sense and in the same
7113 time in client we can use the same protocol routines for normal
7114 key exchange and to key agreement packet handling as well.
7116 * Added to both client's and server's KE protocol context the
7117 SilcSKEKeyMaterial pointer to save the key material. We will
7118 bring the key material to the protocol's final callback by doing
7119 this. The final callback must free the key material.
7121 * Added SKE's packet_send callback into client's KE protocol
7122 context so that the caller can choose what packet sending function
7123 is used. This way we can use different packet sending when
7124 doing normal SKE when doing key agreement packet handling (in
7125 the key agreement packet handling we do not want to encrypt
7128 * Implemented the responder side of the key agreement routines
7129 in the client. The client can now bind to specified port and
7130 accept incoming key negotiation. The key material is passed
7131 to the application after the protocol is over.
7133 * Implemented the processing of incoming Key Agreement packet
7134 in the client. Added function silc_client_key_agreement to
7137 * Implemented the intiator side of the key agreement routines
7138 in the client. The client can now initiate key agreement with
7139 another remote client. The key material is passed to the
7140 application after the protocol is over.
7142 * Created client_keyagr.c to include all the key agreement
7145 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7146 SILC_TASK_CALLBACK except that it is not static.
7148 * Created client_notify.c and moved the Notify packet handling
7149 from the client.[ch] into that file.
7151 * Created client_prvmsg.c and moved all private message and
7152 private message key routines from the client.[ch] into that file.
7154 * Create client_channel.c and moved all channel message and
7155 channel private key routines from the client.[ch] into that file.
7157 * Changed silc_client_get_client_by_id_resolve to resolve with
7158 WHOIS command instead of IDENTIFY command, in the file
7159 lib/silclient/idlist.c.
7161 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7163 * Implemented the SKE's responder side to the Client library.
7165 * When FAILURE is received to the protocol do not trust it
7166 blindly. Register a timeout to wait whether the remote closes
7167 the connection as it should do it, only after that process the
7168 actual failure. This was changed to both client and server.
7170 * Added client_internal.h to include some of the structures
7171 there instead of client.h in lib/silcclient/.
7173 * Added function silc_task_unregister_by_callback to unregister
7174 timeouts by the callback function.
7176 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Some "Incomplete WHOIS info" errors has been appearing on the
7179 log files. Took away the entry->userinfo check from WHOIS
7180 reply sending. The entry->userinfo is now " " if client did not
7181 provide one. I thought this was fixed earlier but something
7182 is wrong still. Let's see if the error still appears.
7184 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7186 * Fixed a minor bug in the login when the channel key is
7187 re-generated in the server. It used to generate the key in
7188 wrong order and thus caused problems in the channel traffic.
7190 * Fixed a minor bug in channel key distsribution after
7191 KICK command. The key was not sent to the router even though
7194 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * Added silc_ske_process_key_material_data as generic routine
7197 to process any key material as the SILC protocol dictates. The
7198 function is used by the actual SKE library but can be used by
7199 applications as well. This relates to the private message keys
7200 and the channel private keys since they must be processed the
7201 same way the normal SILC session keys. The protocol dictates
7202 this. Affected files: lib/silcske/silcske.[ch].
7204 Added also silc_ske_free_key_material to free the
7205 SilcSKEKeyMaterial structure.
7207 * Defined silc_cipher_set_key function to set the key for
7208 cipher without using the object's method function. The affected
7209 files: lib/silccrypt/silccipher.[ch].
7211 * Implemented silc silc_client_add_private_message_key,
7212 silc_client_add_private_message_key_ske,
7213 silc_client_del_private_message_key,
7214 silc_client_list_private_message_keys and
7215 silc_client_free_private_message_keys functions in the
7218 Added functions silc_client_send_private_message_key to send
7219 the Private Message Key payload and silc_client_private_message_key
7220 to handle incoming Private Message Key payload.
7222 * Added Cipher field to the Private Message Key payload to set
7223 the cipher to be used. If ignored, the default cipher defined
7224 in the SILC protocol (aes-256-cbc) is used.
7226 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Removed lib/silcclient/ops.h file.
7230 Redefined parts of the SILC Client Library API. Created new
7231 file silcapi.h that deprecates the ops.h file and defines the
7232 published Client Library API. Defined also private message key
7233 API and channel private key API into the file.
7235 This is the file that the application must include from the
7236 SILC Client Library. Other files need not be included by
7237 the application anymore.
7239 * Added new key_agreement client operation callback and also
7240 defined the Key Agreement library API for the application.
7242 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7245 is used by clients to request key negotiation between another
7246 client in the SILC network. If the negotiation is started it
7247 is performed using the SKE protocol. The result of the
7248 negotiation, the secret key material, can be used for example
7249 as private message key.
7251 Implemented the Key Agreement payload into the files
7252 lib/silccore/silauth.[ch].
7254 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Redefined ciphers for the SILC protocol. Added some new ciphers
7257 and defined the key lengths for the algorithms. Changed the
7258 code accordingly. The default key length is now 256 bits.
7260 * Fixed SKE key distribution function silc_ske_process_key_material
7261 when the key length is more than 128 bits. The default key
7262 length in SILC is now 256 bits.
7264 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7265 to indicate unsupported algorithm.
7267 * Renamed rijndael.c to aes.c and all functions as well.
7269 * Fixed a long standing channel key setting bug in client library.
7270 Weird that it has never surfaced before.
7272 * Fixed bug in channel deletion. If the entire channel is removed
7273 then it must also delete the references of the channel entry
7274 from the client's channel list as the client's channel entry and
7275 the channel's client entry share same memory.
7277 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Implemented CONNECT and SHUTDOWN commands in the client.
7281 * Implemented CLOSE command to the client.
7283 * Added the function silc_idlist_find_server_by_name into the
7284 files silcd/idlist.[ch].
7286 Added the function silc_idlist_find_server_by_conn into the
7287 files silcd/idlist.[ch].
7289 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * DIE command was renamed to SHUTDOWN. Updated the both code
7294 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7295 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7297 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7300 * Added function silc_server_create_connection function to create
7301 connection to remote router. My server implementation actually
7302 does not allow router to connect to normal server (it expects
7303 that normal server always initiates the connection to the router)
7304 so the CONNECT command is only good for connecting to another
7307 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7310 or some other client was kicked from the channel.
7312 Implemented the handling of the notify type to both client
7315 Implemented silc_server_send_notify_kicked to send the KICKED
7316 notify. It is used to send it to the server's primary router.
7318 * Implemented the KICK command into server and client.
7320 * Added `query' argument to the silc_idlist_get_client function
7321 to indicate whether to query the client from server or not if
7324 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7325 to indicate that the client is not channel founder.
7329 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Removed the rng context from SilcPacketContext structure and
7332 changed that the packet routine uses the Global RNG API.
7334 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Added support for quit message that client can "leave" on the
7337 channel when it quits the SILC. It is ditributed inside the
7338 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7340 Added silc_server_free_client_data that will take the
7341 signoff message as argument.
7343 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7345 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7347 * Updated parts of the protocol specification to keep it up
7350 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7352 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7353 payloads in one packet.
7355 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7356 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7357 use now the new List flag.
7359 * Also deprecated the following packet types: REPLACE_ID,
7360 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7362 * Added list support for Notify packet in server.
7364 * Added silc_server_send_notify_channel_change to send the
7365 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7366 the silc_server_send_replace_id.
7368 * Added silc_server_send_notify_nick_change to send the
7369 NICK_CHANGE notify type. Deprecates the function
7370 silc_server_send_replace_id.
7372 * Added silc_server_send_notify_join to send the JOIN notify type.
7373 Deprecates the function silc_server_send_new_channel_user.
7375 * Added silc_server_send_notify_leave to send LEAVE notify type.
7376 Deprecates the function silc_server_send_remove_channel_user.
7378 * Added silc_server_send_notify_cmode and
7379 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7380 types. Deprecates the silc_server_send_set_mode function.
7382 * Added SERVER_SIGNOFF notify type to indicate that server has
7383 quit. This means that all clients on the channel from that
7384 server will drop. This can be also used when netsplit happens.
7386 Deprecated REMOVE_ID packet type since it is not needed anymore
7389 Added silc_server_send_notify_server_signoff to send the
7390 SERVER_SIGNOFF notify type. Deprecates the function
7391 silc_server_send_remove_id.
7393 Added also silc_server_send_notify_signoff to send the
7394 SIGNOFF notify type.
7396 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7397 SILC protocol from this day on. Changed the protocol
7398 specification as well.
7400 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7401 notify type. It is used between routers to notify about
7402 topic changes on a channel.
7404 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7407 * Partly updated the protocol specification to comply with the
7408 changes now made. It is still though a bit outdated.
7410 * The JOIN notify type now takes one extra argument <Channel ID>.
7411 The packet used to be destined to the channel but now the
7412 JOIN type may be sent as list thus it is impossible to
7413 destine it to any specific channel. By adding this argument
7414 it is again possible.
7416 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Added CREDITS file. The CHANGES and CREDITS file will appear
7419 in the distribution as well.
7421 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7423 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7424 types in the server's silcd/packet_receive.c.
7426 * Implemented CMODE and CUMODE to work in router environment.
7428 * Fixed minor encoding and decoding buglet from the
7429 lib/silccore/silcmode.c.
7431 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7434 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7436 * Changed all SilcConfigServer* and silc_config_server* to
7437 SilcServerConfig* and silc_server_config*, respectively.
7440 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7442 * Associated the ID (client or server ID) to the Authentication
7443 Payload to avoid any possibility of forging. Updated the
7444 protocol specification and the code accordingly.
7446 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * The RSA key length is now save to the RsaKey context in the
7449 key generation process in lib/silccrypt/rsa.c. The key length
7450 is now used to figure out the maximum size of the block allowed
7451 to be encrypted/signed.
7453 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7454 is equivalent to the silc_mp_mp2bin but does not allocate any
7457 * Changed silc_mp_mp2bin API to take length argument. If it is
7458 non-zero then the buffer is allocated that large. If zero, then
7459 the size is approximated using silc_mp_sizeinbase, which however
7462 * Created Global RNG API which is global RNG that application can
7463 initialize. After initializing, any routine anywhere in the
7464 code (including library) can use RNG without allocating a new
7465 RNG object. This was done to allow this sort of use of the
7466 RNG in code that has no chance to allocate RNG object. All
7467 applications currently allocate this and many routines in the
7468 library use this. Affected file lib/silccrypt/silcrng.[ch].
7470 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7471 it to use the Global RNG API.
7473 * Defined Authentication Payload into protocol specification that
7474 is used during SILC session to authenticate entities. It is
7475 used for example by client to authenticate itself to the server
7476 to obtain server operator privileges.
7478 Implemented this payload into the lib/silccore/silcauth.[ch].
7479 Implemented also routines for public key based authentication
7480 as the new protocol specification dictates.
7482 Moved definitions of different authentication methods from
7483 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7485 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7486 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7487 silc_pkcs_verify_with_hash functions into the file
7488 lib/silccrypt/silcpkcs.[ch].
7490 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * The client entry's userinfo pointer must be always valid.
7493 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7494 will fail since it requires the userinfo. Now, the userinfo
7495 is allocated as "" if actual userinfo does not exist. Actually,
7496 it must exist and it is totally Ok to drop client connections
7497 that does not announce the userinfo. However, we will make
7498 this workaround for now.
7500 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7501 to return the remote port by socket.
7503 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7505 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7506 SILC_SERVER_PENDING_EXEC and added an new macro
7507 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7508 data or when error occurs while processing the pending command.
7510 Added new argument `destructor' into silc_server_command_pending
7511 and to the SilcServerCommandPending object. This destructor is
7512 now called after calling the pending callback or if error occurs
7513 immediately. If error occurs the actual pending callback won't
7514 be called at all - only the destructor. The destructor may be
7515 NULL if destructor is not needed.
7517 All this applies for client library code as well. Similar
7518 changes were made there as well for the pending commands.
7520 In the client, the application must now allocate the
7521 SilcClientCommandContext with the silc_client_command_alloc
7524 * Added reference counter to the SilcServerCommandContext. Added
7525 function silc_server_command_alloc and silc_server_command_dup
7528 Same type of functions added to the client library for the same
7531 * Removed the cmd_ident from IDListData away since it is now
7532 global for all connections. It is the command identifier used
7533 in command sending and with pending commands. The affected file
7536 * Added reference counter to the SilcSocketConnection objecet to
7537 indicate the usage count of the object. The object won't be
7538 freed untill the reference counter hits zero. Currently only
7539 server uses this, and client ignores it. The client must be
7540 set to use this too later. The affected files are
7541 lib/silccore/silcsockconn.[ch]. Added also the function
7542 silc_socket_dup to increase the reference counter.
7544 This was mainly added because it is possible that the socket
7545 is removed underneath of pending command or other async
7546 operation. Now it won't be free'd and proper DISCONNECTING
7547 flags, etc. can be set to avoid sending data to connection that
7548 is not valid anymore.
7550 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7551 the connection. After that it sets SILC_SET_DISCONNECTED.
7552 It is, however, possible that the socket data is not still freed.
7553 The silc_server_packet_process now checks that data is not
7554 read or written to connection that is DISCONNECTED. The socket
7555 get's freed when the reference counter hits zero.
7557 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Changed the client operation API: channel_message operation's
7560 `sender' is now the client entry of the sender, not the nickname
7561 and the `channel' is the channel entry, not the channel name.
7563 In the private_message operation the `sender' is now also the
7564 client entry of the sender not the nickname.
7566 Affected file is lib/silcclient/ops.h and all applications
7567 using the client operations.
7569 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7571 * Moved the calling of ops->connect() from connect_to_server_final
7572 into receive_new_id functin since that is the point when the
7573 client is actually allowed to send traffic to network. The
7574 affected file is lib/silcclient/client.c.
7576 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7578 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7579 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7580 (if needs broadcasting) instead of broadcasting the packets one
7581 by one which would make a burst in the network traffic.
7583 * Added `broadcast' argument to the functions in silcd/server.[ch]
7584 silc_server_create_new_channel[_with_id] to indicate whether
7585 to send New Channel packet to primary router.
7587 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7589 * Added new function into the silcd/server.[ch] files:
7590 silc_server_create_new_channel_with_id to create new channel with
7591 already existing Channel ID.
7593 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7594 lib/silccore/silcpacket.h. This packet is used t send list of
7595 Set Mode payloads inside one packet. Server uses this to set
7596 the modes for the channels and clients on those channels, that it
7597 announced to the router when it connected to it. The protocol
7598 specification has been updated accordingly.
7600 * The silc_server_new_channel did not handle the packet coming
7601 from normal server as it normally does not send that. However,
7602 when it announces its channels it does send it. Implemented
7603 the support for that.
7605 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7606 into the file lib/silccore/id.h.
7608 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7610 * Fixed memory leaks in the functions silc_idlist_del_client,
7611 silc_idlist_del_channel and silc_idlist_del_server in the file
7612 silcd/idlist.c. All of those leaked like a sieve.
7614 * Fixed some small memory leaks in the client's function
7615 silc_client_notify_by_server.
7617 * Added functions into silcd/server.c: silc_server_announce_clients,
7618 silc_server_announce_channels and silc_server_announce_server.
7619 These functions are used by normal and router server to announce
7620 to its primary router about clients, channels and servers (when
7621 router) that we own. This is done after we've connected to the
7624 These functions effectively implements the following packet types:
7625 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7626 and SILC_PACKET_NEW_ID_LIST.
7628 * Added new functions into the silcd/packet_receive.[ch]:
7629 silc_server_new_id_list, silc_server_new_channel_list and
7630 silc_server_new_channel_user_list to handle the incoming
7631 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7633 * Added support of changing Channel ID in the function
7634 silc_server_replace_id. If the server that announces a channel
7635 to the router already exists in the router (with same name but
7636 with different Channel ID), router is responsible to send
7637 Replace ID packet to the server and force the server to change
7638 the Channel ID to the one router has.
7640 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7641 client that the Channel ID has been changed by the router. The
7642 normal server sends this to the client. Client must start using
7643 the new Channel ID as the channel's ID.
7645 Implemented handling of this new type into lib/silcclient/client.c
7646 into the function silc_client_notify_by_server.
7648 * Added new function silc_idlist_replace_channel_id into the files
7649 silcd/idlist.[ch] to replace the Channel ID.
7651 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Call silc_server_command_identify_check always when processing
7654 the IDENTIFY command in silcd/command.c
7656 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7659 send keepalive packets. The packet can be sent by clients,
7660 servers and routers.
7662 Added function silc_socket_set_heartbeat into the file
7663 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7664 If not set, the heartbeat is not performed. The actual
7665 heartbeat is implemented in the low level socket connection
7666 library. However, application is responsible of actually
7669 Added silc_server_send_heartbeat to send the actual heartbeat
7670 packet into silcd/packet_send.[ch]. Server now performs
7671 keepalive with all connections.
7673 * Added silc_task_get_first function into lib/silcutil/silctask.c
7674 to return the timeout task with shortest timeout. There was a bug
7675 in task unregistration that caused problems. TODO has been
7676 updated to include that task system must be rewritten.
7678 * The client library will now resolve the client information when
7679 receiving JOIN notify from server for client that we know but
7680 have incomplete information.
7682 * Rewrote parts of silc_server_remove_from_channels and
7683 silc_server_remove_from_one_channel as they did not remove the
7684 channel in some circumstances even though they should've.
7686 * Encryption problem encountered in server:
7688 The LEAVE command used to send the Channel Key packet to the
7689 router immediately after generating it. However, the code
7690 had earlier sent Remove Channel user packet but not immediately,
7691 ie. it was put to queue. The order of packets in the router
7692 was that Channel Key packet was first and Remove Channel User
7693 packet was second, even though they were encrypted in the
7694 reverse order. For this reason, MAC check failed. Now, this
7695 is fixed by not sending the Channel Key packet immediately but
7696 putting it to queue. However, this is more fundamental problem:
7697 packets that are in queue should actually not be encrypted
7698 because packets that are sent immediately gets encrypted
7699 actually with wrong IV (and thus MAC check fails). So, packets
7700 that are in queue should be encrypted when they are sent to
7701 the wire and not when they put to the queue.
7703 However, the problem is that the current system has not been
7704 designed to work that way. Instead, the packet is encrypted
7705 as soon as possible and left to the queue. The queue is then
7706 just purged into wire. There won't be any fixes for this
7707 any time soon. So, the current semantic for packet sending
7710 o If you send packet to remote host and do not force the send
7711 (the packet will be in queue) then all subsequent packets to the
7712 same remote host must also be put to the queue. Only after the
7713 queue has been purged is it safe again to force the packet
7716 o If you send all packets immediately then it safe to send
7717 any of subsequent packets through the queue, however, after
7718 the first packet is put to queue then any subsequent packets
7719 must also be put to the queue.
7721 Follow these rules and everything works fine.
7723 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7725 * Added new function silc_server_remove_clients_by_server to
7726 remove all client entries from ID list when the server connection
7727 is lost. In this case it is also important to invalidate all
7728 client entires as they hold the invalid server entry. This
7729 fixes fatal bug when server has lost connection and will reconnect
7732 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7734 * Made some sanity checks to silc_server_daemonise like to check
7735 whether the requested user and group actually exists.
7737 * Added sanity check to SKE's silc_ske_responder_finish to check
7738 that the public and private key actually is valid.
7740 * Invalidate the client's nickname when receiving Replace ID
7741 packet and the Client ID is being replaced. This means that the
7742 server will query the nickname if someone needs it (client)
7745 * Sort the ID Cache in client library when the ID Cache data
7746 has changed (needs sorting).
7748 * Do not allow for SILC client to create several connections to
7749 several servers. The client does not support windows right now
7750 and generating multiple connections causes weird behaviour.
7752 Irssi-silc client does support windows and can handle several
7753 connections without problems, see: www.irssi.org and SILC plugin.
7755 * Fixed some places where client was added to the IDList. The
7756 rule of thumb is following (in order to get everything right):
7757 If the client is directly connected local client then the
7758 `connection' argument must be set and `router' argument must be
7759 NULL to silc_idlist_add_client function. If the client is not
7760 directly connected client then the `router' argument must
7761 bet set and the `connection' argument must be NULL to the
7762 silc_idlist_add_client function.
7764 * The funtion silc_server_packet_send_local_channel actually did
7765 not check whether the client was locally connected or not. It
7766 does that now. Fixed a bug related to LEAVE command.
7768 * Fixed Remove Channel User payload parsing bug in server's
7769 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7771 * The server's silc_server_save_channel_key now checks also the
7772 global ID list for the channel as it might not be in the local
7773 list. Fixed a bug related to LEAVE command.
7775 * Is this the end of the [<unknown>] buglet that has been lurking
7776 around for a long time? A little for loop fix in server's
7777 silc_server_command_whois_parse that is used by both IDENTIFY
7778 and WHOIS command. At least, this was a clear bug and a cause
7779 of one type of [<unknown>] buglet.
7781 * WHOIS and IDENTIFY commands call the function
7782 silc_server_command_[whois/identify]_check function even if
7783 we are not router server.
7785 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * Added --with-gmp configuration option. If set the GMP
7788 is always compiled in the SILC source tree. If not set then
7789 it is checked whether the system has the GMP3 installed. If
7790 it has then the GMP won't be compiled (the system's headers
7791 and library is used), if it doesn't have it then the GMP is
7792 compiled in the SILC source tree.
7794 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7796 * Changed RSA private exponent generation to what PKCS #1
7797 suggests. We try to find the smallest possible d by doing
7798 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7799 not security fix but optimization.
7801 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * Added new config entry [Identity] to fork the server and run
7804 it as specific user and group. A patch from Bostik.
7806 * Imported Dotconf configuration library into lib/dotconf.
7807 This will be used to create the SILC configuration files later.
7808 It will appear in the distsribution after this commit.
7810 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * A big code auditing weekend happening. Auditing code for
7813 obvious mistakes, bugs and errors. Also, removing any code
7816 Removed files for being obsolete:
7818 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7819 inline in the file lib/silcutil/silcbuffer.h)
7821 o lib/silcutil/silcbufutil.c (the header has inline versions)
7823 Changed code to fix possible error conditions:
7825 o The buffer formatting routines now check that the destination
7826 buffer really has enough space to add the data. This applies for
7827 both buffer formatting and unformatting
7828 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7829 unformatting was changed to accomodate following rules:
7830 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7831 sent to the function while XXX_*STRING will not allocate or copy
7832 the data into the buffer. Instead it sets the pointer from the
7833 buffer into the pointer sent as argument (XXX_*STRING used to
7834 require that the pointer must be allocated already). This change
7835 makes this whole thing a bit more consistent and more optimized
7836 (note that the data returned in the unformatting with XXX_*STRING
7837 must not be freed now). The routines return now -1 on error.
7839 o Tried to find all code that use buffer_format and buffer_unformat
7840 and added return value checking to prevent formatting and
7841 especially unformatting errors and possible subsequent fatal
7844 o Changed ske->x and ske->KEY to mallocated pointers in
7845 lib/silcske/silcske.h. Fixed possible data and memory leak.
7847 o Added return value checking to all *_parse* functions. Fixed
7848 many memory leaks as well.
7850 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7851 so that buffer overflows would not happen. All code now also
7852 checks the return value as it can fail.
7854 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Added reconnection support to server if the normal server looses
7857 its connection to the router (for example if router is rebooted).
7858 The server performs normal reconnection strategy implemented
7859 to the server. Affected file silcd/server.c.
7861 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Added new packet type SILC_PACKET_SET_MODE that is used to
7864 distribute the information about changed modes (for clients,
7865 channels and clients channel modes) to all routers in the
7866 network. Updated the protocol specification accordingly.
7868 Added functions into silcd/packet_send.c and
7869 silcd/packet_receive.c: silc_server_send_set_mode,
7870 silc_server_set_mode.
7872 Added new files silcmode.[ch] into lib/silccore that implements
7873 the encoding and decoding of Set Mode Payload. Added new type
7874 SilcSetModePayload. Moved the definitions of different modes
7875 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7877 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7879 * Oops, a little mistake in server's connection authentication
7880 protocol. The protocol is not ended with FAILURE but with
7881 SUCCESS if the authentication is Ok. :) Affected file is
7884 * Implemented NICK_CHANGE notify handling in server in the file
7885 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7886 the local clients on the channel. After the changing nickname
7887 in router environment snhould work and the [<unknown>] nickname
7888 should appear no more.
7890 The silc_server_replace_id function that receives the Replace ID
7891 payload now sends the NICK_CHANGE notify type also in the file
7892 silcd/packet_receive.c
7894 * Changed WHOIS and IDENTIFY command to support the maximum amount
7895 of arguments defined in protocol specs (3328 arguments). This
7896 fixed a bug that caused problems when there were more than three
7899 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7901 * Added extra parameter, command identifier, to the
7902 silc_client_send_command so that explicit command identifier
7905 Changed that ID list routines uses specific command identifier
7906 when sending WHOIS/IDENTIFY requests to the server so that they
7907 can be identified when the reply comes back.
7909 Affected files lib/silcclient/command.[ch],
7910 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7912 * Added `sender' argument to silc_server_packet_send_to_channel
7913 to indicaet the sender who originally sent the packet to us
7914 that we are now re-sending. Ignored if NULL. Affected file
7915 silcd/packet_send.[ch].
7917 * Added some server statistics support in silcd/server_internal.h
7918 SilcServerStatistics structure and around the server code. Also
7919 send some nice statistics information when client is connecting
7922 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7924 * Fixed channel ID decoding in server's JOIN command reply in
7925 silcd/command_reply.c
7927 * Fixed braodcasting of replace ID payload to not to send it if
7928 we are standalone server in silcd/packet_receive.c.
7930 * Fixed all channel message sending routines to not to send
7931 packets to clients that has router set, since they are routed
7932 separately in the same function earlier. Affects file
7933 silcd/packet_send.c and all channel packet sending functions.
7935 * In USERS reply, res_argv[i] are not allocated, the table
7936 is allocated. Thus changed that free the table, not its
7939 * In server's whois_check and identify_check if the client is
7940 locally connected do not send any WHOIS commands - they are not
7943 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7945 * Fixed some minor bugs in client when sending WHOIS command. The
7946 arguments was in wrong order.
7948 * Removed statis function add_to_channel from server in
7949 silcd/command.c that was previously used with the joining but
7952 * Tested USERS command in router environment successfully with two
7953 routers, two servers and two clients.
7955 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7957 * Reorganized the USERS command and command reply in client library
7958 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7959 When the command is given by user we register a pending command
7960 callback that will reprocess the command after the reply has been
7961 received from the server. When reprocessing the packet we then
7962 display the information. Thus, the USERS information is displayed
7963 now in the command callback instead of in the command reply
7964 callback. The processing of the command is same as previously
7965 when server has sent the command reply in the JOINing process.
7967 * Added to USERS command in silcd/command_reply.c to join the client,
7968 we didn't use to know about, to the channel after we've created
7969 a client entry for it. Also, for clienet we did know already still
7970 check whether it is on the channel or not and add it if not.
7972 * Removed silc_server_command_join_notify as the function and its
7975 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Changed the client's pending command handling to the same as the
7978 server's pending command handling. It is also now possible to
7979 execute command reply functions from other command reply
7980 function as the function callbacks for commands and command
7981 replies are one and same. The pending commands are not static
7982 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7983 in client connection context. Thus, pending commands are server
7984 connection specific as it is convenient.
7986 Changed the function silc_client_command_pending and
7987 silc_client_command_pending_del and added new function
7988 silc_client_command_pending_check. Removed the
7989 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7992 * Added cmd_ident, current command identifier, to the client
7993 connection context in lib/silcclient/client.h to keep track on
7994 command identifiers used in command sending. Client's command reply
7995 function handling now supports the mandatory command identifiers.
7997 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7998 funtions in client to fully support pending command callbacks.
8000 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8001 as one of the arguments to the application in the command reply
8004 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8005 before first releasing SILC but came back. Now it is removed again
8006 and should come back nomore. The FORWARDED flag was used only
8007 by the JOINing procedure by forwarding the command packet to router.
8008 Now, the JOINing procedure has been changed to more generic (due
8009 to various router environment issues) and FORWARDED is not needed
8010 anymore for anything. The protocol specification is yet to be
8013 Now, removed silc_server_packet_forward from server and the flag
8014 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8016 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * Renamed NAMES command to USERS command. The NAMES was named that
8019 due to historical reasons. Now it is renamed. Also, rewrote
8020 parts of the USERS command. The nickname list is not sent anymore
8021 by the server. Only Client ID and mode lists are sent in the USERS
8022 command. Changed this also to the protocol specification.
8024 The client now resolves the names and stuff after it receives
8025 the USERS list from the server when joining to the channel.
8027 * WHOIS and IDENTIFY commands has been changed to support multiple
8028 Client ID's per command. One can now search for multiple users
8029 in the network by sending only one WHOIS or IDENTIFY command.
8030 Changed the code and the protocol specifications.
8032 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8033 uses silc_server_command_whois_parse to parse the request. */
8035 * If normal server, do not parse the WHOIS and IDENTIFY requests
8036 before sending it to the router. Saves some time.
8038 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8040 * Fixed JOIN command on client library. Wrong number of arguments
8041 used to crash the client.
8043 * Added silc_server_channel_has_global function to check whether
8044 channel has global users or not.
8046 * Added silc_server_channel_has_local function to check whether channel
8047 has locally connected clients on the channel.
8049 * The silc_server_remove_from_one_channel now checks whether the
8050 channel has global users or not after given client was removed from
8051 the channel. It also checks whether the channel has local clients
8052 on the channel anymore. If it does not have then the channel entry
8053 is removed as it is not needed anymore.
8055 * The silc_server_notify now checks on JOIN notify whether the joining
8056 client is one of locally connected or global. If it is global then
8057 the channel has now global users on the channel and that is marked
8058 to the channel entry. Also, it now saves the global client to
8059 global list who is joining and JOINs it to the channel. This is
8060 for normal server, that is.
8062 Changed silc_server_send_notify_on_channel,
8063 silc_server_packet_relay_to_channel and
8064 silc_server_packet_send_to_channel check if we are normal server
8065 and client has router set (ie. global client) do not send the
8066 message to that client, as it is already routed to our router.
8068 * Implemented LEAVE notify type handling in silc_server_notify
8071 * Tested LEAVE command in router environment successfully. Tested
8072 with two routers, two servers and two clients.
8076 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8078 * Implemented SIGNOFF notify type handling in silc_server_notify
8081 * silc_server_remove_id now removes the client entry from all channels
8082 it has joined and thusly sends SIGNOFF notify type.
8084 * Rewrote the NAMES list generation in server by removing two excess
8085 loops. The lists are created now inside one loop.
8087 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8089 * silc_server_remove_channel_user checks now also global list
8090 for channel and client.
8092 * silc_server_new_channel_user checks now both local and global
8093 list for channel and client. Fixed a bug in client id decoding.
8094 Used to decode wrong buffer.
8096 * silc_server_channel_message checks now both local and global
8097 list for channel entry.
8099 * Tested channel joining (hence JOIN) in router environment
8100 successfully. Tested with two routers, two servers and two
8103 * Tested channel message sending in router environment successfully.
8105 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8107 * Added silc_server_save_channel_key into server.[ch] to save the
8108 received channel key in Channel Key payload processing. It is
8109 also used in JOIN command reply handling.
8111 Equivalent function silc_client_save_channel_key added into
8112 client.[ch] into client library.
8114 * Changed JOIN command reply to send information whether the channel
8115 was created or not (is existing already) and the channel key
8116 payload. Changed protocol specs accordingly.
8118 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8119 the request was sent by ID and not by nickname. Crashed on
8122 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8124 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8125 now correctly save the received data.
8127 * silc_server_free_sock_user_data now notifies routers in the
8128 network about entities leaving the network.
8130 At the same time implemented functions silc_server_remove_id
8131 and silc_server_send_remove_id to receive and send REMOVE_ID
8132 packets. The packet is used to notify routers in the network
8133 about leaving entities. The ID removed will become invalid in
8136 * Added function silc_idlist_del_server into server. Removes and
8137 free's server entry from ID list.
8139 * silc_server_private_message function now checks, if we are router,
8140 that the destination ID really is valid ID, naturally.
8142 * In router when NEW_ID packet is received (for new client) the
8143 hash of the Client ID is saved in the ID Cache but the
8144 client->nickname is set to NULL, instead of putting the hash
8147 IDENTIFY command now also checks that client->nickname must be
8148 valid. If it is not if will request the data from the server who
8149 owns the client. Added new function
8150 silc_server_command_identify_check.
8152 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8153 to set the command to already allocated Command Payload.
8155 * Tested private message sending in router environment with two
8156 routers, two servers and two clients. Fixed minor bugs and now
8159 * Fixed segfault from client's NAMES command. Used to crash if
8162 * Forwarded packets must not be routed even if it is not destined
8163 to the receiver. Changed server code comply with this.
8165 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8167 * Added `require_reverse_mapping' boolean value to ServerParams
8168 structure. If TRUE (not default) the server will require that
8169 the connecting host has fully qualified domain name.
8171 If the reverse mapping is not required and hostname could not be
8172 found the IP address is used as hostname.
8174 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8176 * Implemented version string checking to both client and server.
8177 The check is incomplete currently due to the abnormal version
8178 strings used in development version of SILC.
8180 * Changed all command functions in server to use the new
8183 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Changed char *data to unsigned char *data in ID Cache system to
8186 support binary data as ID Cache data. Changed code to support
8187 binary data in lib/silccore/idcache.c.
8189 * Renamed silc_server_packet_relay_command_reply to
8190 silc_server_command_reply as it is normal packet receiving
8191 function. Rewrote the function to accept command replys for
8192 servers and not only for clients.
8194 * Mark remote router always as registered server if we are connecting
8195 to it. Otherwise, commands sent by the router to us are ignored.
8197 * All ID List find routines now returns the ID Cache Entry pointer
8198 as well if requested.
8200 * WHOIS command works now in router environment, tested with two
8201 routers, two servers and two clients.
8203 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8204 in router environment (as it is almost equivalent to WHOIS) but
8205 hasn't been tested thoroughly. Added new functions:
8207 silc_server_command_identify_parse
8208 silc_server_command_identify_send_reply
8209 silc_server_command_identify_from_client
8210 silc_server_command_identify_from_server
8212 * Disabled route cache adding because adding two different ID's with
8213 same IP replaces the old cache entry thus giving wrong route.
8214 The entry->router->connection is always the fastest route anyway
8215 so route cache may not be needed. Of course, new routes maybe
8216 established after receiving the ID when the entry->router->connection
8217 might not be anymore the most optimal.
8219 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * Add route cache for received ID for fast routing.
8223 * Added silc_server_packet_route to route received packet on router
8224 that is not destined to us.
8226 * Renamed silc_server_get_route to silc_server_route_get.
8228 * Added id_string and id_string_len fields into SilcServer to
8229 include encoded ServerID for fast comparing without excess
8230 encoding of the ID's.
8232 * Cleaned up WHOIS command on server side. Added following static
8235 silc_server_command_whois_parse
8236 silc_server_command_whois_check
8237 silc_server_command_whois_send_reply
8238 silc_server_command_whois_from_client
8239 silc_server_command_whois_from_server
8241 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8242 arguments in command replies. All command functions should be
8243 updated to use this macro.
8245 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8247 * Minor typo fixes on command reply handling on server.
8249 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8251 * Added silc_server_command_add_to_channel internal routine to add
8252 the client to the channel after router has created the channel and
8253 sent command reply to the server.
8255 * Added generic silc_server_send_command to send any command from
8258 * Use static buffer with ID rendering instead of duplicating data.
8260 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8262 * Fixed a channel user mode bug when joining to a channel server gave
8263 everybody channel founder rights, oops.
8265 * We mark ourselves as the router of the incoming server connection
8266 if we are router ourselves. This way we can check in some packet
8267 sending functions whether it is locally connected server. For
8268 incoming router connections we put NULL.
8270 * For router sending packets locally means now always sending the
8271 packet cell wide; to local clients and local servers. For normal
8272 server sending packet locally means sending it to only local
8275 * Fixed the JOIN command to really work in router environment. If the
8276 channel is created it is always created by the router. Router is
8277 also responsible of making the initial joining to the channel,
8278 sending JOIN notify to the sending server and distributing
8279 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8280 does not exist server doesn't do anything else but forward the
8281 command to the router which performs everything.
8283 * Added silc_server_send_channel_key function to send the Channel Key
8286 * Added silc_server_create_channel_key to create new channel key. The
8287 channel key is now re-generated everytime someone joins or leaves
8288 a channel, as protocol dictates. Note: channel->key_len is the
8291 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8293 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8294 packet_receive.[ch] to separate packet sending and receiving
8295 routines. The server.[ch] now includes everything else including
8296 actual packet processing (writing and reading data) and other
8299 Renamed silc_server_private_message_send_internal to
8300 silc_server_send_private_message. The routine is still though
8301 used only to relay private messages as server does not send
8302 private messages itself.
8304 Renamed silc_server_new_channel to silc_server_create_new_channel
8305 and added new function sicl_server_new_channel that handles the
8306 incoming New Channel packet. Added also new sending function
8307 silc_server_send_new_channel to send New Channel Payload.
8309 * Added new function silc_server_notify to process incoming notify
8310 packet to the server/router. Server may then relay the notify
8311 to clients if needed.
8313 * Added new function silc_server_new_channel_user to process incoming
8314 New Channel User packet. Router will redistribute the packet and
8315 send JOIN notify to its local clients and locally connected servers
8316 if needed. Normal server will send JOIN notify to its local client
8317 on same channel when received this packet. Added also corresponding
8318 sending function silc_server_send_new_channel_user to sent the
8321 * Added boolean route argument to send_notif_to_channel and
8322 packet_send_to_channel functions to attempt to route the packet
8323 if it is TRUE and send only locally if it is FALSE.
8325 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8327 * silc_server_replace_id now broadcasts the received replace ID
8328 packet if it is not broadcast packet already. The router must
8329 broadcast to inform other routers about changed ID.
8331 * Added backpointer to server's router into SilcServer context in
8332 silcd/server_internal.h.
8334 * Fixed silc_server_packet_broadcast to send correct broadcast
8337 * The channel key is now distributed to the local client as soon
8338 as it is received from the router (in router environment) so that
8339 no other packet may be sent for the channel until client has
8342 * silc_server_remove_channel_user now broadcasts the received
8343 Remove Channel User packet if it is not broadcast packet already.
8344 The router must broadcast to inform other routers about removed
8347 * Added users field into SilcPacketContext that is a reference count
8348 of the context. One can increase the reference count by calling
8349 silc_packet_context_dup which is now changed to just increase the
8350 reference count instead of duplicating the data. The reference
8351 count is decresed by calling silc_packet_context_free that will
8352 free the data after the reference count hits zero.
8354 For now on the packet context and everything allocated into it
8355 (including the raw packet from network) must be freed by calling
8356 the new silc_packet_context_free function. Added also new function
8357 silc_packet_context_alloc that must be used now to allocate the
8358 context. This also means that if a routine is asynchronous from
8359 silc_[client/server]_packet_parse_type the packet context must
8360 be duplicated by calling silc_packet_context_dup. Otherwise it
8361 gets free'd after silc_[client/server]_packet_parse_type returns.
8362 Also, one must remember that if packet is duplicated then its
8363 reference count must be decresed by calling the free function as
8364 many times as it was duplicated.
8366 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8367 from both client and server.
8369 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8371 * Made joining to a channel working in router environment.
8373 * Cleaned up JOIN command on server side and create function
8374 silc_server_command_join_channel internal routine to make the
8377 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8379 * Changed silc_command_pending list to SilcDList. Also, added
8380 `ident' field to SilcServerCommandPending structure to identify
8381 the reply and to call correct callback.
8383 Added silc_server_command_pending_check function to replace the
8384 corresnponding macro. The silc_command_pending list is not
8387 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8388 to set identifier to previously allocated Command Payload. It
8389 is used to set identifier for command when resending Command
8392 * Added silc_command_payload_encode_payload to encode Command
8393 Payload buffer from SilcCommandPayload structure.
8395 * Added silc_argument_payload_encode_payload to encode Argument
8396 payload buffer from SilcArgumentPayload structure.
8398 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8400 * Changed WHOIS command to support router connection on server side.
8401 The whois request is always sent to router unless the server is
8402 standalone server. After server has received the reply from the
8403 router will it send the reply to the client.
8405 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8406 broadcast received broadcast packet. The function is used only
8407 by router. The broadcast packet is always sent to the router's
8410 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8411 render given ID to printable string, for log files for example.
8413 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8415 * Made basic router to router connections working. At least they
8416 can now connect to each other but nothing really works the way
8417 they are supposed - yet.
8419 * Added new initiator token to RouterConnection configuration
8420 file in silcd/serverconfig.[ch]. It is used to tell whether we
8421 are the initiator to the remote router or whether we'll expect
8422 the other end to connect.
8424 * Moved registering of listener task to silc_server_init, hence
8425 the server starts listenning as soon as it is run, even if it
8426 does not have connections to other routers. Let's see how well
8429 * Changed default connection retry timeouts for more suitable in
8432 * Removed cipher and such arguments from silc_idlist_add_client
8433 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8434 Added new function silc_idlist_add_data to add the keys and stuff
8437 * Added SilcIDListData structure and added it to SilcClientEntry
8438 and SilcServerEntry as their first field in the structure. This
8439 way we can explicitly cast the ID entries to the SilcIDListData
8440 structure and get common data for the entries. In past, we had
8441 to first check what type of connection it is and then cast it to
8442 correct ID entry type. Now, we can directly cast the opaque
8443 pointer to the SilcIDListData (no matter what ID entry it actually
8444 is) and get the data needed.
8446 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8448 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8449 in some circumstances even if threre were timeout tasks, though not
8450 IO tasks, but tasks anyway. Now fixed.
8452 * Defined SilcServerConnection structure to hold connection specific
8453 stuff about directly connected servers and routers. The definition
8454 is currently in silcd/server_internal.h. I thought about having
8455 a bit more important role fro this struct but for now it is used
8456 only when connecting to other server (or router actually).
8458 * Added connecting retry support in server when connecting to
8459 router(s). The retry feature implement exponential backoff
8460 algorithm. Also, added SilcServerParams structure to hold default
8461 parameters for server. For now, it include these retry settings
8462 and are hard coded. After server is moded to be as Silc Server
8463 Library this structure will be more important.
8465 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8467 * Changed client librarys channel->clients table to SilcList and
8468 changed code accordingly.
8470 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8472 * Changed client's channel table to SilcList and changed code
8473 accordingly. Also changed SilcChannelClientEntry to include back-
8474 pointer to the channel so that client entry can use that structure
8475 as list as well and we have fast cross-reference to the channel.
8476 This change dramatically decreased the complexity of channel
8477 handling with client entry and vice versa (removed one extra
8478 loop when searching for channel entry from many functions).
8480 * Changed server->sim from table to SilcDList and changed code
8483 * NAMES command can now be used from user interface. It will show
8484 the user list on the channel, neatly.
8486 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8487 Code now saves realname of the user if it becomes available.
8489 * Renamed configure.in to configure.in.pre and made ./prepare
8490 script to automatically add correct version string to
8491 configure.in which it creates from configure.in.pre.
8493 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8495 * NAMES command reply now shows users mode with the nickname when
8498 * Moved silc_client_ch[u]mode[_char] functions from
8499 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8500 place sucks, they are utility functions and should be in some
8503 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8505 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8508 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8512 * Added TRQ (efficient deque and list library) into lib/trq. This is
8513 a very good list library that is currently used in the SILC. Defined
8514 SilcList API over the library because I didn't like the API very
8515 much. See lib/trq/silclist.h for the API and examples of how to
8516 use the API. Fixed various places in the code to use the new
8517 SilcList API. The SilcList is meant for lists that has a structure
8518 already defined as a list. It is not suitable to add just some
8519 context to the list (in TRQ, the context is the list actually).
8521 So, I defined SilcDList that can be used for the purpose where
8522 predefined list structure does not exit. This can be used as
8523 such list. Now some context just can be added to the SilcDList.
8524 Currently this list is not used in the SILC just yet, though there
8525 are a lot places where this can replace dynamically allocated
8526 tables and I will fix these places, later, to use SilcDList.
8527 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8528 and use TRQ internally).
8530 Also fixed some annoying warning messages that the original TRQ
8531 code generated. Also minor changes to TRQ's Makefile.in.
8533 * Added support for querying by Client ID to both WHOIS and
8534 IDENTIFY commands into server, as required by the protocol.
8536 * Removed method function pointers from SilcBuffer structure. They
8537 weren't used to anything and just increased the context size for
8538 no good reason. This change also made silc_buffer_alloc and
8539 silc_buffer_free functions inline functions.
8541 * Disabled command flooding detection support until it's fixed so
8542 that it accepts commands in but does not execute them more than once
8545 * Added silc_net_localhost(), to return local hostname, into
8546 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8547 that must be initialized before calling silc_client_init.
8549 * Added new function: silc_server_send_notify_on_channels to send
8550 notify messages to all channels client has joined. It is assured
8551 that the message is sent only once per client.
8553 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8554 lib/silcutil/silcutil.[ch] as silc_format function. The new
8555 function is generic and is used by server as well, not only by
8556 the logging routines.
8558 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8559 the provided version string was not acceptable. Added new function:
8560 silc_ske_check_version into lib/silcske/silcske.h. The function
8561 must be implemented by the application (client or server) and it
8562 does not reside in the SKE library. The function checks the version
8563 string remote end sent.
8565 * Added back pointers (to opaque context and to SilcSocketConnection)
8566 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8568 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8569 duplicate packet context structure.
8571 * Changed `notify' client operation to send same arguments as client
8572 receives from server except for ID's. ID's are mapped to correct
8573 ID entry and that is returned. Also, if channel entry is not sent
8574 by server but the notify is for channel the channel entry is sent
8575 to application (otherwise application doesn't know that it is for
8576 channel (library gets it from packet's Destination ID)).
8578 * Added silc_client_remove_from_channels into client library to
8579 remove a client from all channels it has joined to. Used when
8580 received SIGNOFF notify from server. Added also new function
8581 silc_client_replace_from_channels to replace old ID entry with
8582 new ID entry on all channels. Used when received NICK_CHANGE
8585 * Fixed ID Cache list handling in silc_idlist_get_client in
8586 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8587 to get (or query) client by ID.
8589 * Updated TODO list.
8591 * Added connection authentication status message defined by the
8592 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8593 support for these into the code in client and server side.
8595 * Added generic function silc_client_send_command to send any command
8596 with variable argument list. Application should use this function
8597 to send commands if the command functions provided by the library
8598 does not suite for the application's user interface needs.
8600 * Added new `failure' client operation. Application is notified about
8601 received failure packet if client is executing a protocol. In this
8602 case the protocol's execution has failed.
8604 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8605 is required by the protocol.
8607 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8608 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8611 * Added status flag to SilcSKE object to indicate realtime status
8612 of the SKE protocol.
8614 * Application receives now exactly same command reply arguments as
8615 the library receives from server. However, if ID is received the
8616 corresponding ID entry is returned to the application (eg. Client
8617 ID is mapped to correct SilcClientEntry entry and that is returned).
8618 Changed command_reply client operation due to this change.
8620 * Changed all ID's in commands and in command replys as ID Payloads.
8621 Change affected both client and server side codes.
8623 All ID's sent in SILC network (with execption of ID's in SILC
8624 Packet header) are sent in ID Payload to support variable length
8627 * Server now notifies nick changes and notifies all clients on
8628 the channels about the new nickname (about the new Client ID,
8631 * Implemented CMODE command to change channel modes. Supports all
8632 channel modes defined by the protocol specs except ban and invite
8633 lists. (Also, private channel key mode is supported but support for
8634 setting private channel key in client is missing, thus, this mode
8635 has no effect on client side (except that server requires that the
8636 client uses private channel key and normal channel traffic does not
8639 Also, invite mode works per se, but INVITE command does not work
8640 yet correctly, so you can set channel as invite only channel but
8641 inviting clients to the channel does not work (it is yet to be
8642 thought what's the best way to do it).
8644 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8645 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8646 Implemented CUMODE command to change user's mode on the channel.
8647 Supports all modes defined by the protocol specs.
8649 * Added NAMES command reply to return users modes on the channel.
8651 * Removed unnecessary and slow ciphers from lib/silccrypt.
8653 * Set SO_KEEPALIVE option to connection sockets by default.
8655 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8657 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8658 redefined the Notify Payload into protocol specs.
8660 * Added silc_id_payload_parse_id to get ID directly from raw
8663 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8665 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8666 accept searching by Client ID as well.
8668 * Added support for LEAVE and SIGNOFF notify types in client library.
8670 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8671 to parse ID Payload from raw data.
8673 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8675 * Added flags parameter into silc_ske_assemble_security_properties
8676 function in lib/silcske/silcske.[ch].
8678 * Changed notify client operation to fit better for notify messages
8679 sent by server. The notify payload received from server is now
8680 passed to the application (after parsing it to SilcNotifyPayload).
8681 It is application's responsibility to retrieve the arguments
8682 from the payload and show the message the way it wants. The message
8683 sent by server is implementation specific.
8685 * Changed public keys to comply with the protocol specification.
8686 Old public keys are not supported anymore and are not compatible.
8688 * Removed nickname from Channel Payload as the latest draft removed
8689 it. The client must resolve the nickname from the NAMES command
8690 reply received when it joined the channel.
8692 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8694 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8696 * Fixed some errors in protocol specification drafts.
8698 * Created lib/silccore/silcnotify.c to implement Notify Payload
8699 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8700 generic payloads described by protocol specifications. The file
8701 includes implementations for ID Payload and Argument Payload.
8703 * Changed Command Payload implementation to use the new Argument
8704 Payload. Changed command_xxxx_payload to command_payload_xxxx
8705 to comply with SILC coding conventions.
8707 * Added suppport for Argument Payload handling in Notify Payload
8708 implementation as protocol requires it. Added the new support
8709 into server and client lib as well.
8711 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8713 * Added support for multiple nicknames on same channel. [n] is
8714 added locally to the nickname if there are more than one same
8715 nicknames on the channel.
8717 * Server now sends all nicknames that matched WHOIS request.
8718 Client also shows the list received from server.
8720 * Added TOPIC command to client side. User can now set and show
8721 current topic on channel.
8723 * Added MOTD command to client and server. Also, server sends the
8724 motd when client connects to the server.
8726 * Changed version strings to comply ISO 8601.
8728 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8730 * Fixed protocol error handling in client library. It should now
8731 cope even if the SKE fails for some reason.
8733 * Made new protocol specification drafts for submitting to IETF.
8735 * Implemented TOPIC command to server in silcd/command.c.
8737 * Added two new notify types into lib/silccore/silcnotify.h:
8738 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8739 notify nickname change and topic setting/change on a channel.
8741 * API change of command_reply operation in client library. The
8742 application gets now the status type received from server as well.
8744 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8746 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8748 * Cras fixed and optimized the packet handling even further and
8749 it should work now. Minor change to the prototype of function
8750 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8752 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8754 * Added new function into lib/silcutil/silcschedule.[ch]:
8755 silc_schedule_with_fd to select() a specified fd. The function
8756 returns after timeout expires or data arrives or goes. The
8757 function is used by packet routines to wait that all data is
8758 received from network.
8760 * Fixed data reading from network in lib/silccore/silcpacket.c.
8761 The code now assures that all data is read from the fd and then
8762 continues packet processing. This was a bug fix since the code
8763 used to drop some data in some circumstances.
8765 * Added new function into lib/silcclient/client.[ch]:
8766 silc_client_start_key_exchange to start key exchange after
8767 connection has been established to server. The code internally
8768 now uses this funtion but its main purpose was to provide it
8769 for applications that perform their own connecting. After
8770 application has created a connection it merely calls this
8771 function to start the key exchange between client and server.
8772 The library takes care of everything else after that.
8774 Updated also lib/silcclient/README to explain the usage of
8777 * Do not send to application information that connection has
8778 been established. Application gets notified it by connect
8781 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8783 * Applied cras's patch to add silc_schedule_one function. The
8784 function runs scheduler once and returns.
8786 * Fixed the scheduler after cras messed it up. The timeout
8787 handling works now as it's supposed to work.
8789 * Added into lib/silccore/ silcnotify.h to include notify
8790 message types support. Changed silc_server_send_notify*
8791 functions, in server.[ch], to support those new notify types.
8792 Added the support for the notify types into client library,
8793 as well. Added new notify client operation into ops.h in
8796 * Changed silc_server_packet_send_to_channel to send normal
8797 packets instead of just channel message packets. The function
8798 is now used to send the notify packets to channels. It is not
8799 used to send channel message packets anymore, as server never
8802 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8803 va_arg()s as it seems to require it nowadays. I guess, if SILC
8804 is compiled with older va_arg() the new code should work anyway.
8806 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8808 * Splitted core library. Core library (lib/silccore) includes
8809 now only SILC protocol specific core (and common) components.
8810 Created new utility library (lib/silcutil) that includes more
8811 generic purpose stuff. The stuff for util library was taken
8812 from the old core library. This was minor and easy split.
8814 * Created SILC Client Library (lib/silcclient) that includes
8815 implementation of the SILC client without user interface. This
8816 was major move from silc/ directory. The code has been changed
8817 so that it is transparent towards the user interface. The
8818 silc/ directory includes now the same user interface as before
8819 and it uses the new client library. Read lib/silcclient/README.
8820 Basicly, the client library performs everything else related
8821 to SILC except user interface handling. Also, configuration
8822 files are considered to be part of user interface and library
8823 does not handle them.
8825 This change also changed a lot of structures, function naming etc.
8826 Most important change was that SilcClientWindow object was
8827 renamed to SilcClientConnection in the client library. Created
8828 also new file lib/silcclient/ops.h. Also added new files
8829 silc/local_command.[ch] and silc/client_ops.[ch].
8831 All these changes were made to make it easier for user interface
8832 designers to create what ever user interface for the SILC client
8835 It is also expected that the server will be moved to lib
8836 directory as well and SILC Server Library will be created;
8837 sometimes in the future.
8839 * Removed Local commands from lib/silccore/silccommand.h as
8840 they are application specific and new client library does not
8841 handle any of those anymore.
8843 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8844 old client implementation in silc/.
8846 * Added support for callback functions in SILC_LOG_* macros.
8847 Application can now set its own callbacks that will be called
8848 instead of using the default functions that will always print
8849 the debug messages to stderr (or stdout). Also, debugging can
8850 now be disabled by setting silc_debug to FALSE and re-enabled by
8851 setting it to TRUE. Note, that logging will still work even
8852 if debugging is disabled.
8854 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8855 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8856 silc_log_reset_debug_callbacks.
8858 * To enable debugging in silc client one must give now -d
8859 option on command line.
8861 * Changed silc_schedule_init to automatically allocate task queues
8862 if they are not allocated before calling it.
8864 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8866 * Added GMP 3.1 into math library.
8868 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8870 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8871 a channel in SILC network. The packet is used by servers and
8872 routers to notify other routers that user has left a channel.
8873 This little feature was missing until now. Added the feature
8874 to protocol specification as well.
8876 Added functions: silc_server_send_remove_channel_user and
8877 silc_server_remove_channel_user into server.[ch].
8879 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8880 lib/silccore/silcpacket.h. However, they are not implemented
8883 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8885 * Fixed joining to a channel and sending channel messages
8886 between server and router. The channel message sending should
8887 now work inside a cell.
8889 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8891 * Fixed the private message sending between server and router.
8892 The private message sending should now work inside a cell.
8894 * Added silc_server_replace_id into server.[ch] to replace
8895 existing ID in the SILC network.
8897 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8898 and silc_idlist_replace_server_id into idlist.[ch] in server.
8900 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8902 * Fixed the server to server connections. Server can again now
8903 connect to router. Router to router connections probably does
8906 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8908 * Added dynamic protocol registering support. Now protocols can
8909 registered and unregistered on the fly. Patch by cras.
8911 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8913 * Added lib/contrib directory to hold routines that some platforms
8914 don't have but are needed by SILC.
8916 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8917 into lin/contrib to provide getopt() and getopt_long() for
8918 those who don't have it.
8920 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8922 * Added AWAY command to client. When away message is set and
8923 client receives a private message packet the client automatically
8924 replies to the sender with the away message.
8926 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8927 bug seemed to be the cause of recent problems when compiling
8930 * Added version detection support to SKE protocol specification
8931 and added the new changes to the SKE implementation as well.
8932 There were other minor changes in the SKE protocol as well.
8934 Many changes in lib/silcske/silcske.[ch] and in
8935 lib/silcske/payload.[ch].
8937 * Added ^U functionality, clear input line. Patch from cras.
8939 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8941 * Mainly small bugfixes on core library. Fixed some debugging
8942 logging and buffer overflow in silclog.c.
8944 * Updated config.sub and config.guess on the distribution tree.
8946 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8948 * Added command lagging support in server. Client may execute
8949 commands now only once in two seconds.
8951 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8953 * Optimized packet reception. MAC computation and checking is now
8954 also more optimized. A lot previously duplicated code is now
8955 used as generic by both client and server.
8957 * Fixed key pair generation in clientutil.c
8959 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8961 * Added into lib/silccore/silcbufutil.[ch] new function;
8962 silc_buffer_realloc.
8964 * Moved generic packet sending/encryption functions to
8965 lib/silccore/silcpacket.[ch] from client and server. Some
8966 rewriting of the functions.
8968 * Moved all generic packet reception/decryption functions to
8969 lib/silccore/silcpacket.[ch] from client and server. The
8970 packet processing is now much cleaner in both client and server.
8971 These were major changes in both client and server.
8973 * Created many common functions in server to do packet sending.
8974 Previously code were duplicated a lot, this has been removed
8977 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8979 * Rewrote major parts of the ID cache system. Don't know
8980 whether it is better now or not but at least the API is more
8983 * Major rewrite on ID cache stuff on client because of the ID
8984 cache API changes. Added idlist.c to client.
8986 * Also major rewrite on ID cache stuff on server as well.
8987 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8988 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8989 in hand, instead they are all put into the ID cache system now.
8990 All server_idlist_* routines uses ID cache now instead of
8991 traversing its own lists (those lists does not exist anymore).
8992 SilcIDList though still exists. Also, SilcXXXEntry's are
8995 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8997 * Finally made the SKE implementation compliant to the protocol
8998 specification. All mp integers are now binary encoded as
8999 opposed being HEX encoded.
9001 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9004 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9005 functions: silc_[encode/decode]_pem. Also added function
9006 silc_encode_pem_file to PEM encode with newlines ('\n') for
9009 * SILC public keys are now encoded either PEM or binary. Same
9010 option is for private keys as well. By default private keys
9011 are binary encoded and public keys PEM encoded. Silly HEX
9012 encoding were removed.
9014 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9015 function to create fingerprints.
9017 * Fixed a bug in SHA1; does not change the original data anymore.
9019 * Partly implemented INFO command on client and server side.
9020 Fixed CLEAR command. Changes to SERVER command; show current
9021 server(s) when giving command without arguments. Added
9022 VERSION command to client.
9024 * Added check to server that unregistered connections cannot
9025 execute commands (unless it is specificly allowed).
9027 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9029 * Fixed screen refresh.
9031 * Fixed channel joining bug from client. On some circumstances
9032 client tried to join to a channel it had already joined.
9034 * Added public key verification process into client's protocol.c.
9035 The client now verifies the public key from user and saves
9036 it into ~./silc/serverkeys/ directory.
9038 Added into: clientutil.[ch]: silc_client_verify_server_key.
9040 * Changed SKE protocol's silc_ske_initiator_finish function
9041 to accept callback function that verifies the received public
9042 key. Removed old silc_ske_verify_public_key function.
9044 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9046 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9047 silc_pkcs_private_key[_data]_set.
9049 * Made the password and public authentication more cleaner in
9050 server's protocol.c.
9052 * Removed historic and obsolete protocol `channel_auth' from
9053 both client and server.
9055 * Removed wrong way of sending command status messages from
9056 server to client in server's command.c. The old way violated
9057 protocol specification.
9059 Changes to silccore/silccommand.[ch]: removed
9060 silc_command_encode_status_payload -> not needed anymore,
9061 changed silc_command_encode_payload_va to accept extra
9062 argument on variable argument list. The argument type must
9063 now be provided to the function. Also, added new function:
9064 silc_command_encode_reply_payload_va which is same as
9065 normal command_encode_payload_va except command status type
9066 is provided as extra argument.
9068 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>

9073 Added silc_client_check_silc_dir, silc_client_create_identifier
9074 and silc_client_load_keys.
9076 * Implemented SILC protocol compliant public key. Added public
9077 and private key saving to and loading from files.

9090 * Added silc_server_get_route (route.[ch]) to get connection
9091 data for the fastest route for given ID.

9094 were re-defined in the SILC Protocol Specification and the
9095 implementation now complies with the specification.
9097 * Implemented PING command on client and server.
