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

1084 include the IV in the MAC as well. This way all relevant
1085 parts of the channel message payload are authenticated also
1086 with the channel message MAC (and not only by packet MAC).
1087 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1088 Affected file is lib/silccore/silcchannel.c.
1090 * Fixed the SKE to save the remote version, since the
1091 silc_ske_parse_version mistakenly checked wrong version,
1092 after it replaced the start payload. Affected files are
1093 lib/silcske/silcske.[ch].
1095 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1097 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1098 string utility functions. Added there also new functions
1099 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1100 Affected files lib/silcutil/silcstrutil.[ch].
1102 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1103 files are lib/silcutil/silcstrutil.[ch].
1105 * Defined that the security property fields in SKE SHOULD be
1106 UTF-8 encoded, defined that version string MUST be US-ASCII
1107 encoded, defined that passphrases sent in connection
1108 authentication protocol MUST be UTF-8 encoded. Implemented
1109 these to the client and server. Defined also that other
1110 passphrases sent in the protocol MUST be UTF-8 encoded.
1111 Affected files are lib/silcske/silcske.c,
1112 lib/silcclient/protocol.c, silcd/protocol.c,
1113 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1115 * Changed the silc_client_close_connection interface to not
1116 need the SilcSocketConnection which should not be visible
1117 to application. Affected files are lib/silcclient/client.c
1118 and lib/silcclient/silcclient.h.
1120 * Rewrote the text for Private Message Key Payload in the
1121 protocol specification. Protocol TODO #11.
1123 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1125 * Upgraded the protocol version to 1.1, updated protocol specs
1128 * Added the nickname as new argument to NICK_CHANGE notify and
1129 added it to protocol specs and implemented it to client and
1130 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1131 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1132 lib/silcclient/client_notify.c.
1134 * Added the killer's client ID to the KILLED notify and added
1135 it to protocol specs and implemented it to client and server.
1136 Protocol TODO #13. Affected files are silcd/command.c,
1137 silcd/packet_receive.c, packet_send.[ch],
1138 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1139 The killer's client entry is now returned to application in
1140 the `notify' client operation.
1142 * Fixed the Max Argument fields that had too large value set
1143 in the protocol specs. Protocol TODO #14.
1145 * Added the LEAVE command reply to return the ID of parted
1146 channel. Updated protocol specs and implemented it to the
1147 client and server. Protocol TODO #15. Affected files are
1148 silcd/command.c, lib/silcclient/command_reply.c. The channel
1149 entry is now returned to application in the `command_reply'
1152 * Rewrote the version SKE version checking in client libary
1153 and in server to use the silc_parse_version_string. Affected
1154 files are lib/silcclient/protocol.c, silcd/protocol.c.
1156 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1157 commands that was missing it, and updated protocol specs and
1158 the server implementation. Protocol TODO #10. The affected
1159 file is silcd/command.c.
1161 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1162 generic reply to a generic request (REQUEST flag), and
1163 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1164 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1165 to define the payload for DATA flag. Added the flags to
1166 the implementation. Protocol TODO #9. Affected file is
1167 lib/silccore/silcchannel.h.
1169 Changed the client library to return the message length
1170 to application as well in the channel_message and private_message
1171 client operations. Affected files are
1172 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1173 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1174 and lib/silcclient/client_ops_example.c.
1176 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1177 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1178 the channel. Updated protocol specs and impelemented this
1179 to client and server. Protocol TODO #6. Affected files are
1180 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1181 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1183 Added new options m and M to CMODE command in Irssi SILC
1184 client to set these modes.
1186 * Deprecated all administrative commands from SILC protocol
1187 since they are highly implementation specific commands.
1188 Updated protocol specs. Moved the old commands in
1189 implementations to private range of command types. Affected
1190 files are silcd/command.c, lib/silcclient/command.c and
1191 lib/silcclient/command_reply.c. Protocol TODO #8.
1193 * Fixed a bug in server where sending unknown command crashes
1194 the server. Affected file silcd/command.c.
1196 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Added SILC_PROTOCOLVERSION macro to check protocol version
1199 of a socket connection. The affected file is
1200 lib/silcutil/silcsockconn.h.
1202 * Added better error logging in rekey protocol. Affected file
1205 * Do not check public key types in SKE during rekey. Affected
1206 file lib/silcske/payload.c.
1208 * Fixed the rekey protocol with PFS, which was totally broken.
1209 Affected file silcd/protocol.c.
1211 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1213 * Some client implementations quit network by doing first LEAVE
1214 and then immediately SIGNOFF (like Bombyx). We now do check
1215 after a short time after LEAVE notify and check whether the
1216 client is still valid after LEAVE, and if not we remove it from
1217 cache. Affected file is lib/silcclient/client_notify.c.
1219 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1221 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1222 it's good not to have security holes here.
1224 * Fixed a negative refcount situtuation for the config context.
1225 Affected file is silcd/serverconfig.c.
1227 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1229 * ROBOdoc documented lib/silcutil/silcutil.h.
1231 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1233 * Optimized even more the SilcPacketContext structure. Now
1234 totally saved 16 bytes of memory per context after optimization.
1235 Affected files are lib/silccore/silcpacket.[ch].
1237 * Made strict checks for valid SILC IDs. Affected file is
1238 lib/silccore/silcid.c.
1240 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1242 * Changed the object argument for silc_cipher_register,
1243 silc_hash_register, silc_hmac_register and silc_pkcs_register
1244 to const. Affected files are lib/silccrypt/silccipher.[ch],
1245 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1247 * Changed the silc_get_username and silc_get_real_name to
1248 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1250 * Fixed the Irssi SILC Client to use the silc_get_username and
1251 silc_get_real_name insted of glib routines since the glib
1252 routines only corrupt stack. Fixes the Irssi SILC to work in
1253 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1255 * Fixed the Irssi to not use g_get_home_dir since it crashes
1256 or returns garbage on cygwin and corrupts stack. Added function
1257 get_home_dir to Irssi routines. Affected files are
1258 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1260 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1262 * Made some structure optimizations. SFTP memory FS MemFSEntry
1263 entry structure. Optimized SilcTask structure. Optimized
1264 SilcPacketContext structure.
1266 Affected files lib/silcsftp/sftp_fs_memory.c,
1267 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1269 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1271 * And yet again reverted back the config thing since Johnny
1272 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1275 * Fixed memory leaks from config object. Affected files are
1276 silcd/serverconfig.[ch].
1278 * Added support for adding new connections to the server in rehash.
1279 After rehash they take effect.
1281 Added support for changing the maximum allowed connections in
1282 rehash. The number can grow but going smaller is not supported.
1284 Added function silc_server_num_sockets_by_remote to the
1285 silcd/server_util.[ch].
1287 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1289 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1291 * Added preliminary checking during config parsing for a valid
1292 public/private key and removed further checks in the code.
1293 Affected files are silcd/serverconfig.[ch], server.c.
1295 * Moved functions silc_server_drop() and silc_server_daemonise()
1296 from server.c to silcd.c since they are stricly related to
1297 the application activity.
1299 * Reverted a small part of the automatic ref/unref since
1300 it caused a double unref in some situations. Affected
1301 files are silcd/silcd.[ch], server.c, serverconfig.c.
1303 * Added some .cvsignore files in the lib directory.
1305 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1307 * Fixed silc_net_gethostbyaddr to correctly resolve by
1308 address. Affected file lib/silcutil/silcnet.c.
1310 * Fixed the notify relaying to client. The HMAC to be used
1311 with relayed packets ws wrong and caused decryption failure
1312 at the client end. Affected file is silcd/packet_receive.c.
1314 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1316 * Created new branch silc_protocol_1_0_branch.
1318 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1320 * Changed the silc_server_config_* routines to be SilcServer
1321 independent. They are now officially application specific code
1322 and not part of generic server implementation. Affected files
1323 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1325 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1327 * Added automatic referencing of config context in the
1328 silc_server_config_alloc, and automatic unreferencing in the
1329 silc_server_config_destroy. Affected files are
1330 silcd/serverconfig.[ch], silcd/silcd.c.
1332 * Fixed the silc_log_quick handling in the logging routines.
1333 It didn't log quickly when it was TRUE. Affected file is
1334 lib/silcutil/silclog.c. Also the flush delay was set even
1335 if it was 0 in config file. Affected file is
1336 silcd/serverconfig.c.
1338 * Added support for changing key pair of the server in rehash.
1339 Affected file silcd/server.c.
1341 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1343 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1344 too early, before getting the channel entry. Affected file
1345 is silcd/packet_receive.c.
1347 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1349 * Added functions silc_server_config_[ref/unref], these are used
1350 to prevent that the config object is destroyed.
1352 No longer directly affect global variables silc_log_quick and
1353 silc_log_delay, they are first cached inside the config object
1354 and then applied with silc_server_config_setlogfiles().
1356 silc_server_config_set_defaults() is now internal to
1357 serverconfig.c, there are no reasons to show this internal stuff
1360 Affected files are silcd/serverconfig.[ch].
1362 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1363 fprintf's to stderr, since some code may be executed again after
1364 the server went into the background. Affected files are
1367 * Added rehash support. Added function silc_server_rehash() that
1368 will perform all the basic tasks of the rehashing procedure.
1370 * Added command line option `-x, --hexdump'. This will enable the
1371 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1372 The option `--hexdump' implies `--debug'.
1374 * Fixed a bad bug in the logging APIs (silcutil library) where
1375 the application would crash after calling silc_log_reset_all().
1377 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1379 * Fixed the KICKED notify handling in client library to
1380 correctly remove the channel and all entries from the
1381 channel when I was kicked. This bug crashed the client.
1383 Fixed yet another but in KICKED notify handling to remove
1384 the kicked client correctly from the channel.
1386 Affected file is lib/silcclient/client_notify.c.
1388 * Fixed a minor bug in looking up correct client entry
1389 in KICKED notify in server. Affected file is
1390 silcd/packet_receive.c.
1392 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1393 sources correctly to distribution. Fixes --with-gmp option.
1395 * Removed the manual rehashing from ID Cache, and changed it
1396 to use the SILC Hash Table's auto rehash feature. Affected
1397 file is lib/silccore/silcidcache.c.
1399 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1401 * Fixed a bug in the silc_client_nickname_format function that
1402 handles the multiple same nickname formatting. Two clients
1403 with same nickname caused problems after the first one left
1404 and rejoined. It didn't format the nickname correctly.
1405 Affected file is lib/silcclient/idlist.c.
1407 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1409 * Don't change the topic if olod topic is same as new one.
1410 Affected file is silcd/packet_receive.c.
1412 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1414 * Added cross-reference support to the SILC Documentation
1415 generator. All types across all HTML files are now cross-
1416 referenced. Affected files util/robodoc/generator.c and
1417 scripts/silcdoc/silcdoc.
1419 * Added file lib/silcutil/silctypes.h to include all the
1420 arithmetic type definitions and some macros. Removed
1421 includes/bitmove.h and moved macros to silctypes.h.
1423 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1425 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1427 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1429 * Added `type' argument to silc_id_payload_parse_id function which
1430 now returns the type of the ID to the sent pointer. Affected
1431 file is lib/silccore/silcid.[ch].
1433 * Added check for CMODE_CHANGE notify type that mode change is
1434 allowed by the sender. Affected file silcd/packet_receive.c.
1436 * Added check for CUMODE_CHANGE notify type that mode change is
1437 allowed by the sender. Affected file silcd/packet_receive.c.
1438 Added the ID type as CUMODE_CHANGE notify type as argument
1439 to the `notify' client operation. Affected files are
1440 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1442 * Added function silc_client_add_server to the client library.
1443 Added support for resolving also channel and server info when
1444 received unknown entity in notify packet. Affected files are
1445 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1447 * Added function silc_command_get_status to return the command
1448 status from the command reply's argument payload. Affected files
1449 are lib/silccore/silccommand.[ch].
1451 * Added check for KICKED notify type that the kicking is
1452 allowed by the client. Affected file silcd/packet_receive.c.
1454 * Created function silc_get_input which can be used to get input
1455 (echo on or off) from user on command line. Affected files are
1456 lib/silcutil/silcutil.[ch].
1458 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1460 * Optimized silc_server_packet_relay_to_channel function.
1461 Added new function silc_channel_message_payload_encrypt which
1462 can be called directly if channel message payload needs to
1463 be encrypted and is already encoded (no need to call _encode
1464 function). Packet relaying is now done by router without any
1465 extra memory allocations. Affected files are
1466 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1467 silcd/packet_send.c.
1469 * Fixed the INVITE notify handling. It took wrong arguments
1470 as invite list and invite delete. Affected file is
1471 silcd/packet_receive.c.
1473 * Added check for TOPIC_SET notify type that the topic change is
1474 allowed by the client. Affected file silcd/packet_receive.c.
1476 * Added check for INVITE notify type that inviting is allowed by
1477 the client. Affected file silcd/packet_receive.c.
1479 * Changed the silc_server_client_on_channel to return the
1480 SilcChannelClientEntry as well. Moved the function
1481 silc_server_check_cmode_rights to server_util.[ch].
1482 Affected files are silcd/server_util.[ch], silcd/command.c.
1484 * Added function silc_server_check_umode_rights to check whether
1485 changing client's user mode is allowed. Added check for
1486 UMODE_CHANGE notify type that the umode change is allowed
1487 by the client. Affected files are silcd/server_util.[ch],
1488 silcd/packet_receive.c and silcd/command.c.
1490 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1492 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1493 ID length. It ignored that ID can be IPv6 based as well.
1494 Affected file lib/silccore/silcpacket.h.
1496 * Fixed the silc_id_id2str and silc_id_str2id to take the
1497 IPv6 address offset's into consideration. Affecte file is
1498 lib/silccore/silcid.c.
1500 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1502 * Fixed the internal Unix scheduler functions to check for
1503 NULL context they may receive. The affected file is
1504 lib/silcutil/unix/silcunixschedule.c.
1506 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1508 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1509 can specify different directory with --home command line
1510 parameter. Affected files irssi/src/silc/core/client_ops.c,
1513 * SILC-specific commands aren't now executed if the active server
1514 isn't of SILC-type, so there won't be problems with having
1515 IRC and SILC protocol support in same client. Affected files
1516 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1519 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1521 * Improved the signal support in SILC Schedule. Added new
1522 function silc_schedule_signal_call which is used by application
1523 to mark a signal to be called. It is now safe to perform
1524 any kind of tasks in signal callbacks since it is guaranteed
1525 that the application specified signal callback is called
1526 after the signal is over. Affected files are
1527 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1529 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1531 * Added `name' field to SilcChannelPrivateKey to represent
1532 application given name for the key. Moved also the context from
1533 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1534 Added the `name' argument also to the function
1535 silc_client_add_channel_private_key.
1537 Added function silc_client_current_channel_private_key to set the
1538 current channel private key in use.
1540 Added "change" command to KEY command which can be used to change
1541 the current channel private key. Bound the command also to
1542 alt+K (Alt+Shift+k).
1544 Also affected files lib/silcclient/client_channel.c,
1545 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1547 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1549 * Added silc_rng_get_byte_fast function in to the
1550 lib/silccrypt/silcrng.[ch].
1552 * Changed the interface of silc_packet_assemble and the
1553 silc_packet_send_prepare. If silc_packet_assmble is now
1554 called the application does not call silc_packet_send_prepare
1555 because the library will call it automatically. These
1556 interfaces now also return a reference to the outgoing buffer
1557 which includes the assembled packet, which the application can
1558 use to encrypt the packet.
1560 Affected files are lib/silccore/silcpacket.[ch],
1561 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1562 silcd/packet_send.c, server_backup.c and packet_receive.c.
1564 * Fixed a packet sending bug on very high load, where outgoing
1565 packet queue wasn't handled correctly and packets got corrupted.
1566 Affected files are lib/silcutil/*/silc*sockconn.c,
1567 lib/silcclient/client.c and silcd/server.c.
1569 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1571 * Added macro SILC_PACKET_DATALEN which can be used during
1572 packet assembling to check whether the data to be added to
1573 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1574 len is truncated until it fits it.
1576 Added checks for maximum length of channel message payload and
1577 private message payload also.
1579 Added checks for maximum packet length in server and in
1582 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1583 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1584 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1585 lib/silcclient/client_prvmsg.c.
1587 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1589 * Added silc_server_packet_queue_purge call to the
1590 silc_server_disconnect_remote to assure that all data in the
1591 queue before disconnecting is sent to the network. Affected
1592 file silcd/server.c.
1594 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1596 * Added the deleting of server's own ID cache entry to the
1597 silc_server_free function. Free also everything else that
1598 has been allocated in silc_server_init. The affected file
1601 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1603 * Added functions silc_parse_version_string, silc_version_to_num,
1604 and silc_ske_parse_version to parse SILC protocol style version
1605 strings. Affected files lib/silcutil/silcutil.[ch] and
1606 lib/silcske/silcske.[ch].
1608 * Added new configuration params: version_protocol, version_software
1609 and version_software_vendor to specify what version the remote
1610 host must at least be to be able to connect to server. The vendor
1611 string can be regex matched too. Added new function
1612 silc_server_connection_allowed to check maximum number of allowed
1613 connections, and allowed versions for incoming connections.
1614 Affected files are silcd/server.c, server_util.[ch] and
1617 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1619 * Added preliminary support for signals in scheduler. The
1620 signals we care about are now blocked always when the scheduler
1621 is locked. This way we can synchronise the use of signal with
1622 scheduler. It is guaranteed that when signal occurs the scheduler
1623 is not locked, and thus new tasks can be safely added to the
1626 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1627 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1628 Added new platform specific routines
1629 silc_schedule_internal_signals_[un]block and
1630 silc_schedule_internal_signal_[un]register.
1632 Added new functions to SILC Schedule API:
1633 silc_schedule_signal_[un]register. Each signal that application
1634 is going to use should be registered to the scheduler.
1636 Affected files are lib/silcutil/silcschedule.[ch],
1637 lib/silcutil/*/silc*schedule.c.
1639 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1641 * Check for unauthenticated client and server in the
1642 silc_server_new_client and silc_server_new_server functions.
1643 Affected file silcd/packet_receive.c.
1645 * Added function silc_string_is_ascii to check whether given
1646 string is 7-bit ASCII string. Affected files are
1647 lib/silcutil/silcutil.[ch].
1649 * Added function silc_id_is_valid_server_id into the
1650 silcd/serverid.c and added checking for valid Server ID's in
1651 silc_server_new_server. The Server ID must always be based
1652 on the server's public IP address.
1654 * Added logging of DISCONNECT packet message in the server.
1655 Affected file silcd/server.c.
1657 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1659 * Changed all library interfaces that use Global RNG to also
1660 accept SilcRng as argument. Affected files are
1661 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1662 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1663 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1664 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1665 lib/silccrypt/rsa.c.
1667 * Added function silc_pkcs_generate_key to the
1668 lib/silccrypt/silcpkcs.[ch] for applications so that they
1669 don't need to do pkcs->pkcs->init calls anymore.
1671 * Remove SilcSocketConnection from the SFTP API since it really
1672 wasn't needed there. The application has the information
1673 saved in its contexts anyway and the SFTP layer doesn't need
1674 know about it. Affected files lib/silcsft/silcsftp.h and
1675 lib/silcsftp/sftp_[server/client].c.
1677 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1678 The SilcSimContext is not SilcSim.
1680 * Fixed possible buffer overflows in silc_id_render in the
1681 lib/silcutil/silcutil.c.
1683 * On EPOC the global crypto module lists are not used at all
1684 in the crypto library. Added support for using the constant
1685 algorithm list on EPOC. Affected files are
1686 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1689 * Fixed the handling of third parameter of KICKED notify, since
1690 it was mistakenly updated to SILC Protocol 1.0 even though it
1691 is to be included in 1.1. Since it is not in 1.0 it is not
1692 mandatory, and this fix now handles it only if it is provided,
1693 and it is not error if it is not provided. Affected file
1694 lib/silcclient/client_notify.c.
1696 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1698 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1699 client. Affected file irssi/src/silc/core/client_ops.c.
1701 * Merged with Irssi 0.8.4 from irssi.org CVS.
1703 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1705 * Check for valid socket connection in client entries before
1706 sending any messages. Fixes a crash, but doesn't fix some
1707 other underlaying bug that is lurking there. Affected
1708 file silcd/packet_send.c.
1710 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1712 * $usermode, $cumode and $cumode_space expandos shouldn't do
1713 anything with non-SILC server records. Affected file
1714 irssi/src/silc/core/silc-expandos.c
1716 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1718 * Fixed the silc_net_check_[host/local]_by_sock to support
1719 IPv6 bound sockets as well. Now they can return IPv6 addresses
1720 as well. Affected file lib/silcutil/silcnet.c.
1722 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1723 Affected lib/silcutil/unix/silcunixnet.c.
1725 * Fixed ID rendering (at least on some platforms, not NetBSD)
1726 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1728 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1730 * Added silc_hash_public_key and silc_hash_public_key_compare
1731 functions to be used with SilcHashTable. They can be used to
1732 hash public keys and compare public keys in hash table. Affected
1733 file lib/silcutil/silcutil.[ch].
1735 * Added support for specifying multiple public keys for Client
1736 connection section in server configuration file. This makes it
1737 possible to accept multiple public keys from same host, or to
1738 make a section that accepts any incoming host, and have the
1739 accepted public keys listed in the section.
1741 Added functions silc_sever_[find/get]_public_key, added the
1742 support for this actually to all connection sections but only
1743 the Client section is currently allowed to specify multiple
1746 Affected files are silcd/server.c, server_internal.h,
1747 command.c, protocol.c, server_util.[ch], packet_receive.c.
1749 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1751 * Merged Irssi 0.8.2 from irssi.org CVS.
1753 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1755 * If silc_debug is TRUE, also output standard logging messages
1756 to stderr with the debug output.
1758 Made silc_log_reset_all() flushing all channels before returning.
1759 Also fixed some documentation typos.
1761 Affected files are lib/silcutil/silclog.[ch].
1763 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Fixed the server to check correctly the amount of connections
1766 from single host, by checking also the type of the connection.
1767 Fixed also the comparison of number of connections and number
1768 of allowed connections. Affected files are silcd/server.c,
1771 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1773 * Fixed the USERS command reply to save the user's mode on the
1774 channel as well. Fixed JOIN command reply to check whether a
1775 client is on channel already and not join it twice. Affected
1776 file lib/silcclient/command_reply.c.
1778 * Added new file silc-expandos.c into irssi/silc/core/ to return
1779 various stuff for various signal for the statusbar etc. updating.
1780 Now Irssi SILC client prints channel user modes etc. on the
1783 * The user mode (like server/router operator changes) is now shown
1784 on the Irssi SILC client's statusbar. The affected files are
1785 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1787 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1789 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1790 to SILC_SCHEDULE_[UN]LOCK macros.
1792 * Added more error printing to logs in server code. Affected
1793 files silcd/server.c and silcd/protocol.c.
1795 * Fixed -S option parsing in Irssi SILC Client. Affected file
1796 irssi/src/silc/core/silc-core.c.
1798 * Added silc_buffer_alloc_size function. Affected file is
1799 lib/silcutil/silcbuffer.h.
1801 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1803 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1804 constants. Affected files in
1805 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1808 * Changed the internal SFTP Memory FS table to const. Affected
1809 file lib/silcsftp/sftp_fs_memory.c.

1813 * Fixed the buffer formatting and unformatting routines to
1814 check the size of 64 bits types with sizeof(). Affected
1815 file is lib/silcutil/silcbuffmt.c.
1817 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1821 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1823 * Changed all integer type names:
1824 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1825 to avoid collisions with other libraries using same type names
1828 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1830 * Added `prefer_ipv6' argument to the functions
1831 silc_net_gethostbyname[_async]. If it is TRUE it will return
1832 IPv6 address over IPv4. If FALSE IPv4 address is returned
1833 even if IPv6 address was found. Affected files
1834 lib/silcutil/silcnet.[ch].
1836 * Added support silc_net_create_connection[_async] to fallback
1837 to IPv4 address if IPv6 address could not be used (like if
1838 it doesn't work on a specific system). Affected file in
1839 lib/silcutil/unix/silcunixnet.c.
1841 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1843 * Added silc_schedule_reinit function to do the enlarging
1844 of the max tasks handling capabilities of the scheduler.

1847 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1849 * Added automatic extern "C" { ... } for C++ compilers so the
1850 application does not need to define them. Affected file
1851 includes/silcincludes.h.
1853 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1854 old name went against naming convention. Applications now
1855 include "silcclient.h" instead of "clientlibincludes.h".
1856 Removed includes/clientlibincludes.h, it is redundant now.
1858 * Renamed includes/version.h to silcversion.h.
1860 * Added really preliminary support for OS/2 into the util
1861 library. Only thread & mutex API is implemented, others
1862 are still to be implemented. Created the lib/silcutil/os2/
1863 directory. Created also file includes/silcos2.h.
1865 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1870 includes/silcbeos.h.
1872 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1874 * Added proper initializations to silc's irssi code, so it's
1875 now possible to load it as module. Affected files
1876 irssi/src/silc/core/silc-core.c,
1877 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1896 * Added `user_count' to the SilcChannelEntry which now tells the
1897 number of users on the channel. The user count is now saved
1898 in normal server of global channels as well. Affected files
1899 silcd/server.c, idlist.h, packet_receive.c and command.c.
1901 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1902 include file utility functions.
1904 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1905 instead of calling directly OS routines.
1907 * Fixed NICK change printing in Irssi SILC Client. Fixed
1908 KICKED notify printing in Irssi SILC Client. Affected file
1909 irssi/src/silc/core/client_ops.c.
1911 * Fixed a NICK change bug in client library, to not recreate the
1912 client_entry->channels hash table everytime nick is changed.
1913 Affected file lib/silcclient/client.c.
1915 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1917 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1918 the SKE interface a bit.
1920 * Fixed padding problem in PKCS#1. The padding was not actually
1921 random since the random number generator was used incorrectly.
1922 This security bug affects only when encrypting with PKCS#1, and
1923 it is not currently used at all in SILC. SILC only use signing
1924 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1926 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1938 key_exchange_timeout, conn_auth_timeout, connections_max,
1941 Implemented all the new config settings handling in the server.
1943 Optimized the use of SKE Mutual flag usage. Use it only
1944 if connection authentication protocol is not based in public
1947 Renamed all SilcServerConfigSection* to SilcServerConfig*
1948 to have a bit shorter names.
1950 Affected files silcd/serverconfig.[ch], server.[ch], and
1953 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1984 is now done in silc_core_init() which also fixes autoconnecting
1987 Affected files irssi/src/silc/core/silc-core.c,
1988 irssi/src/fe-text/silc.c.
1990 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1992 * Added new configuration options and blocks:
1993 keepalive_secs, reconnect_count, reconnect_interval,
1994 reconnect_interval_max, reconnect_keep_trying and
1995 require_reverser_lookup. Added ConnectionParam block, and
1996 implemented the connection parameters when connecting as
1997 initiator and when accepting connections as responder.
1999 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2000 whether given configuration value has been given already.
2002 Affected files silcd/serverconfig.[c], server.[c].
2004 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2005 algorithm parts and created new file silcalgs.conf, that
2006 is now included from the example_silcd.conf.in.
2008 * Optimized the silc_server_connect_to_router_second to take
2009 the connection configuration object from the SilcServerConnection
2010 object instead of finding it during the connecting phase.
2011 Added the configuration object to SilcServerConnection struct.
2012 Affected files silcd/server_internal.h, server.c.
2014 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2016 * Add the client on channel after it was resolved at the
2017 channel message receiving, and it was not already on the
2018 channel. Affected file lib/silcclient/client_channel.c.
2020 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2022 * Fixed the public key authentication to allocate always the
2023 destination signature buffer instead of using static buffer.
2024 Affected file silcd/protocol.c.
2026 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2028 * Unified the serverconfig.[ch]'s helper function interface.
2029 Affected file silcd/serverconfig.[ch].
2031 * Removed doc/example_silc.conf.in since it is redundant.
2032 The make install will now install irssi/silc.conf file.

2035 config file, allowing both public key and passphrase based
2036 authentication to be set at the same time.
2038 Added `prefer_passphrase_auth' setting in config file which
2039 can be used to set to prefer passwd auth if both passwd and
2040 public key is set. If not set, public key is preferred.
2041 This has effect only when being initiator (responder will try
2044 Added support for authentication with passphrase and public key
2045 at the same time. The passphrase is tried first always since
2046 it is faster to check.
2048 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2050 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2084 as part of Toolkit documentation.
2086 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2088 * Fixed CUMODE_CHANGE notify handling to change the mode of
2089 correct client. Affected file lib/silcclient/client_notify.c.
2091 * Make silc_rng_alloc fail if it cannot allocate the sha1
2092 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2094 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2096 * Fixed the file transfer's key agreement payload to include
2097 zero port also if the hostname is NULL because it could not
2100 Call file transfer monitor callback now also if error occurs
2101 during key agreement protocol.
2103 Changed the silc_client_file_send interface to return the
2104 SilcClientFileError instead of session id. The session ID
2105 is returned into pointer provided as argument.
2107 Check that the file exists locally before sending the
2108 file transfer request at all.
2110 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2112 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2113 error than can occur while key agreement protocol. Affected
2114 file lib/silcclient/silcapi.h.
2116 * Fixed the event_mode CMODE handler to not crash when mode
2117 is changed and +k mode is set in the channel. Affected file
2118 irssi/src/silc/core/silc-channels.c.
2120 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2121 SILC_LOG_WARNING to give out Warning and not Error. Affected
2122 file lib/silcutil/silclog.c.
2124 * Fixed the channel message payload decryption in the function
2125 silc_channel_message_payload_decrypt to not modify the original
2126 buffer before it is verified that the message decrypted
2127 correctly. Otherwise, next time it is called with correct
2128 channel key it won't encrypt since the payload is corrupted.
2129 Affected file lib/silccore/silcchannel.c.
2131 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2133 * Do not constantly resize the window. A fix patch by cras.
2134 Affected file irssi/src/fe-text/screen.c.
2136 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2138 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2139 Affected file lib/silcutil/silcnet.c.
2141 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2143 * Fixed a bug in hash table internal routine for traversing
2144 the table with foreach callback. The current entry may
2145 become invalid in the callback but it was referenced after
2146 the callback returned.
2148 Do not allow auto rehashing of hash table during the
2149 silc_hash_table_foreach operation, for same reasons as it is
2150 not allowed for SilcHashTableList. Affected files are
2151 lib/silcutil/silchashtable.[ch].
2153 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2155 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2156 Win32 DLL. extern's in header files are now declared with
2159 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed private message handling. It used some old code that
2162 caused the client to crash. Affecte file is
2163 lib/silcclient/client_prvmsg.c.
2165 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2167 * Added function silc_client_add_channel,
2168 silc_client_replace_channel_id, and removed functions
2169 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2170 from client library.
2172 * Added cross reference of the joined channels to the
2173 SilcClientEntry, and changed the SilcChannelEntry's
2174 users list to SilcHashTable. The affected files are
2175 lib/silcclient/idlist.[ch].
2177 * Fixed a bug in hash table tarversing. While the hash table
2178 is traversed with SilcHashTableList the table must not be
2179 rehashed. It is now guaranteed that auto rehashable tables
2180 are not rehashed while tarversing the list. Also defined that
2181 silc_hash_table_rehash must not be called while tarversing
2182 the table. Added function silc_hash_table_list_reset that must
2183 be called after the tarversing is over. The affected files are
2184 lib/silcutil/silchashtable.[ch].
2186 * Changed all hash table traversing to call the new
2187 silc_hash_table_list_reset in server and in client library.
2189 * Added function silc_client_on_channel to return the
2190 SilcChannelUser entry if the specified client entry is joined
2191 on the specified channel. This is exported to application as
2192 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2194 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2196 * Fixed founder regaining problem with JOIN command on normal
2197 server. The notify for mode change must be sent always and
2198 not only if !cmd->pending. Affected file silcd/command.c.
2200 * Fixed the WHOWAS command's reply sending to support the
2201 lists correctly. Affected file silcd/command.c.
2203 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2205 * When sending JOIN command to router for processing the
2206 sender's old command identifier was not saved back to the
2207 sender's command context, fixed now. The affected file is
2210 * Create the key in JOIN command of the router did not return
2211 the channel key, added check for this. Affected file is
2214 * Fixed a channel ID update bug in JOIN command reply. Do
2215 not directly upgrade the ID but call the function
2216 silc_idlist_replace_channel_id if the ID was changed.
2217 Affected file silcd/command_reply.c.
2219 * Fixed memory leaks from command calling if it would fail.
2220 Affected file silcd/command.c.
2222 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2224 * Applied patches from cras:
2226 Memory leak fixes around libaries, irssi window resize fix,
2227 new silclist.h and silcdlist.h, all extern inline changed to
2230 * Removed dotconf from lib/dotconf, not needed anymore.
2232 * Removed TRQ from lib/trq, not needed anymore.
2234 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2235 with server connections. Later this will be configurable
2236 in config file after new config file is done. Affected file
2239 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2241 * Fixed a crash in server related to channel announcements.
2242 Affected file silcd/server.c.
2244 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2246 * Fixed memory leaks in silc_server_create_new_channel*
2247 functions. Affected file silcd/server.c.
2249 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2250 which ID was changed. This way the router will send the
2251 user list for the channel again, and server won't be in
2252 desync in some rare circumstances. Affected file is
2253 silcd/packet_receive.c.
2255 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2257 * Check for NULL socket pointer in the function
2258 silc_server_packet_send_to_channel_real. Affected file
2259 silcd/packet_send.c.
2261 * Fixed the BAN notify handling to correctly remove ban
2262 list. Affected file silcd/packet_receive.c.
2264 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2266 * Fixed some header addition to Toolkit distribution in
2267 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2269 * Added lib/silcclient/client_ops_example.h as an template
2270 file for application programmers to quickly start using
2271 the SilcClientOperation functions in their application.
2272 Updated the lib/silcclient/README as well to tell about this
2273 nice file made available.
2275 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2277 * Call silc_server_remove_from_channels when removing client
2278 entry when NO_SUCH_CLIENT_ID was received. Affected file
2279 is silcd/command_reply.c.
2281 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2283 * Added server & router operator statistics updating. Affected
2284 file silcd/packet_receive.c and silcd/command.c.
2286 * Fixed the SERVER_SIGNOFF notify handling on normal server
2287 not to save the history information for clients. Same was
2288 fixed earlier in remove_clients_by_server function, but not
2289 here. Affected file silcd/packet_receive.c.
2291 * Raised the default connection-retry count from 4 to 7 in
2292 server. Affected file silcd/server.h.
2294 * Cancel any possible reconnect timeouts when we start the
2295 key exchange. Affected file silcd/server.c.
2297 * Do not reconnect on connection failure when SCONNECT was
2298 given. Affected files silcd/server.[ch].
2300 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2302 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2304 * Fixed the NICK command to always give the unformatted
2305 nickname to the one giving the NICK command. If unformatted
2306 nickname is cached already it will be formatted and the
2307 local entry will always get the unformatted nickname.
2308 Affected file lib/silcclient/idlist.c.
2310 * Fixed some double frees from client library commands.
2311 Affected file is lib/silcclient/command.c.
2313 * Fixed CUMODE command in server to assure that no one can
2314 change founder's mode than the founder itself, there was a
2315 little bug. Affected file silcd/command.c.
2317 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2319 * Removed the SilcClientCommandDestructor from the client
2320 libary, it is not needed anymore. Affected files are
2321 lib/silcclient/silcapi.h, command[_reply].[ch],
2322 client_notify, idlist.c.
2324 * Fixed GETKEY command to first resolve client, and then
2325 resolve the server only if the client was not found, instead
2326 of resolving both at the same time. Affected file is
2327 lib/silcclient/command.c.
2329 * Added silc_client_start_key_exchange_cb and lookup the
2330 remote hostname and IP address before starting the key
2331 exchange with server. The affected file is
2332 lib/silcclient/client.c.
2334 * The server's public key is now saved using the IP address
2335 of the server and not the servername for the filename.
2336 The hostname public key filename is checked as an fall back
2337 method if the IP address based filename is not found.
2339 Fixed the GETKEY command to save the fetched server key
2340 in correct filename.
2342 Print the remote server's hostname now when new key is
2343 received during connection process. Affected file is
2344 irssi/src/silc/core/client_ops.c.
2346 * Return always our own public key to the client if it asks
2347 for it with GETKEY command. Affected file silcd/command.c.
2349 * Removed the use_auto_addr variable from default config
2350 file since it was in wrong section. Affected file is
2353 * Fixed TOPIC_CHANGE notification to not route it when it
2354 was sent using silc_server_send_notify_to_channel function.
2355 Affected file silcd/command.c.
2357 * Fixed silc_server_send_notify_kicked to send the kicker's
2358 Client ID also, it was missing. Affected files are
2359 silcd/command.c, silcd/packet_send.[ch].
2361 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2363 * Do not save client history information in SERVER_SIGNOFF.
2364 Fixes the bug in normal server that it does not detect
2365 the client becoming valid after the server becomes back
2366 online. Affected file silcd/server_util.c.
2368 * Added `sock_error' field into the SilcSocketConnection
2369 context. When error occurs during socket operation (read
2370 or write) the error is saved. Added also new function
2371 silc_socket_get_error to return human readable socket error
2372 message. Affected files are lib/silcutil/silcsockconn.[ch],
2373 lib/silcutil/unix/silcunixsockconn.c, and
2374 lib/silcutil/win32/silcwin32sockconn.c.
2376 * The server now prints the socket error message in the
2377 signoff for client. Affected file silcd/server.c.
2379 * Fixed the `created' channel information sending from router
2380 to server in JOIN command. Checks now whether the channel
2381 really was created or not and set it according that.
2383 Fixed the JOIN command to use the client entry's current
2384 ID during the joining procedure instead of the one it sent
2385 in the command (it is checked though), since it can change
2386 between the packet processing and command processing, and
2387 would just case unnecessary pain in the client end. Affected
2388 file silcd/command.c.
2390 * Fixed a channel key payload sending to use correct channel
2391 ID when the server was forced to change the channel's ID by
2392 router. Router sent the key payload with the old Channel ID.
2393 Affected file silcd/packet_receive.c.
2395 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2397 * Call silc_server_save_channel_key only if the key payload
2398 was provided in the JOIN command's command reply. Affected
2399 file silcd/command_reply.c.
2401 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2403 * Fixed silc_mp_sizeinbase to return the value correctly with
2404 MPI. Affected file lib/silcmath/mp_mpi.c.
2406 * Fixed the stop_server signal to correctly stop the scheduler
2407 and gracefully stop the server when SIGTERM or SIGINT signals
2408 are received. Affected file silcd/silcd.c.
2410 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2412 * Simple handling of TERM and HUP signals. Also added some log
2413 flushing call around. Affected file is
2416 * Fixed small bugs in silclog.c. Now buffering output will take
2417 effect after 10 seconds since startup: This will ensure that
2418 no important startup messages are lost. Also output redirection
2419 will preserve original format ([Date] [Type] message).
2420 Affected file is lib/silcutil/silclog.c.
2422 * Added two options to the config file, in the logging section:
2423 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2424 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2426 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2428 * Do not print the warning about log files not being initialized
2429 more than once to avoid excess logging. Affected file is
2430 lib/silcutil/silclog.c.
2432 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2433 the SIM copying in make install in Makefile.am.pre.
2435 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2437 * Rewritten silclog APIs. Globally interesting changes follows:
2438 silc_log_set_files() changed to silc_log_set_file().
2439 silc_log_set_callbacks() changed to silc_log_set_callback().
2440 ROBOdoc documented silclog header file.
2441 SilcLogCb now returns bool to wether inihibit the default
2442 handler or not (to keep the old behaviour return always TRUE).
2443 The new APIs should also fix the problem of the
2444 silcd_error.log file that was written in the current directory.
2447 Log files streams will remain opened after silc_log_set_file()
2448 call, means less CPU usage notably on high traffic servers.
2449 File streams are now full buffered, and flushed to the disk
2450 every 5 minutes, lesses HD activity and CPU usage.
2451 Messages can be redirected, allowing admins to configure
2452 one single logfile for all server messages.
2453 the silc_log_quick global variable to activate fast-logging.
2454 Affected files lib/silcutil/silclog.[ch]
2456 * Changed some code to conform new silclog APIs. Affected
2457 files are doc/example_silcd.conf.in, silcd/server.c
2458 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2461 * Fixed a memory leak that could occur in some situations.
2462 Affected file silcd/serverconfig.c.
2464 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2466 * Added the silc_client_del_client to remove the client from
2467 all channels as well. Affected file lib/silcclient/idlist.c.
2469 * Fixed the client library to correctly remove the client
2470 from all channels when the client entry is being destroyed.
2471 Affected file lib/silcclient/client_notify.c, command.c.
2473 * Added auto-nicking support to the client library. If the
2474 applicatio now sets client->nickname it will be sent to the
2475 server after connecting by the library. This way for example
2476 SILCNICK (or IRCNICK) environment variables will have effect
2477 and always change the nickname automatically to whatever
2478 it is wanted. Affected file lib/silcclient/client.[ch].
2480 * Renamed silc_server_command_bad_chars to the
2481 silc_server_name_bad_chars and moved it to the
2482 silcd/server_util.[ch]. Added also new function
2483 silc_server_name_modify_bad to return nickname that
2484 includes bad characters as new nickname without those
2485 bad characters. This check and modify is now used in
2486 silc_server_new_client when the username is initially set
2487 as nickname, so it must be checked to be valid nickname.
2488 Affected file silcd/packet_receive.c.
2490 * The nickname length is now taken from the packet for real
2491 and not trusted to strlen() since it clearly can return
2492 wrong length for nickname including bad characters. This
2493 also applies to channel names. Affected file silcd/command.c.
2495 * Removed the lib/silcsilm/modules directory. Modules are now
2496 compiled into the lib/silcsim. Fixed the copying of the
2497 modules to follow symbolic links in Makefile.am.pre.
2499 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2501 * Fixed silc_string_regexify list creation. Fixes bugs with
2502 BAN and INVITE commands in server. The affected file is
2503 lib/silcutil/unix/silcunixutil.c.
2505 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2507 * Removed the command destructor entirely from the server's
2508 command and command reply routines. It is not needed, and
2509 its usage was buggy and caused crashes. Affected files are
2510 silcd/command[_reply].[ch].
2512 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2514 * Cancel protocol and NULL sock->protocol if timeout
2515 occurred during protocol. Affected file silcd/server.c.
2517 * Cancel protocol timeouts always before calling the final
2518 callback, to assure that after final callback is called
2519 no other state will be called for the protocol anymore.
2520 Affected file silcd/protocol.c.
2522 * Print error log if incoming connection configuration could
2523 not be found. Affected file silcd/server.c.
2525 * Fixed JOIN command to correctly save the founder mode
2526 to the client on normal SILC server, when the channel
2527 was created by the router. Affected file silcd/command.c.
2529 * Fixed LIST command (hopefully) to send correct reply
2530 packets. Affected file silcd/command.c.
2532 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * The silc_packet_receive_process now returns FALSE if the
2535 read data was invalid packet, and TRUE if it was ok.
2537 The server now checks that if unauthenticated connection
2538 sends data and its processing fails the server will close
2539 the connection since it could be a malicious flooder.
2541 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2543 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Make sure the warning about error opening a log file is
2546 printed only once and not everytime it fails (produces
2547 too much useless log). Affected file lib/silcutil/silclog.c.
2549 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2551 * Made the silc_server_daemonise() function more readable.
2552 Affected file silcd/server.c.
2554 * Pid file is now optional, the user may comment it out from
2555 the config file. Removed define SILC_SERVER_PID_FILE, we
2556 don't need a default any longer. Affected file
2557 configure.in.pre, lib/Makefile.am.pre.
2559 * Make some use of the pid file. The server now dies at startup
2560 if it detects a valid pid file on his path. The server would
2561 die anyway in this circumstance, because of the bind() failure.
2562 Affected file silcd/silcd.c.
2564 * No longer compiling lib/dotconf.
2566 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Fixed JOIN command parsing not to crash. Affected file
2569 lib/silcclient/command.c.
2571 * Fied the NICK_CHANGE notify to add the new client entry
2572 even it is resolved. This removes an <[unknown]> nick
2573 thingy bug in the client. Affected file is
2574 lib/silcclient/client_notify.c.
2576 * Do not try to allocate 0 bytes (efence does not like it)
2577 in lib/silccore/silccomand.c when encoding payload.
2579 * Do not take IRCNICK as nickname in Irssi SILC client since
2580 it is not possible to set nickname before hand connecting
2581 the server (TODO has an entry about adding auto-nicking
2584 * Changed the silc_server_command_pending to check whether
2585 there already exists an pending entry with the specified
2586 command, command identifier and pending callback. This is
2587 to fix IDENTIFY and WHOIS related crashes that may register
2588 multiple pending commands with same identifier. Affected
2589 file silcd/command.c.
2591 * Fixed the server to reconnect to the router even if it
2592 was already reconnecting and EOF was received. This to
2593 fix a possibility that the server wouldn't ever try to
2594 auto-reconnect to the router. Affected file silcd/server.c.
2596 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Fixed the server's password authentication to use the
2599 length of the locally saved password, and not the one
2600 sent in the packet. Affected file silcd/protocol.c.
2602 * Fixed same password authentication problem in the
2603 Authentication Payload handling routines in
2604 lib/silccore/silcauth.c.
2606 * Yet another password authentication problem fixed with
2607 channel password handling in silcd/command.c.
2609 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * If first character of string in silc_parse_userfqdn is '@'
2612 then do not parse it. Affected file is
2613 lib/silcutil/silcutil.c.
2615 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Fixed minor bug in IDENTIFY command reply sending, which
2618 caused various weird problems during JOIN when it was
2619 resolving names for users. Affected file silcd/command.c.
2621 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Fixed the IDENTIFY command reply sending to chech better valid
2624 clients. It was possible to send incomplete list of replies.
2625 Affected file silcd/command.c.
2627 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Added silc_client_command[s]_[un]register functions now to
2630 dynamically register the commands in client library. Removed
2631 the static table of commands. This allows the client library
2632 to call commands without causing the application to know about
2633 what commands library has called.
2635 Removed the INFO command reply kludge to detect when the command
2636 was called by library. Now library use its own command reply
2637 function for INFO command.
2639 Added function silc_client_command_call to call a command.
2640 Application can use it to call command, not access the structure
2643 Now all commands that are sent by the client library (not
2644 explicitly sent by application) use own command reply functions.
2646 Affected files around lib/silcclient/ and in
2647 irssi/src/silc/core/.
2649 * Fixed the WHOIS command reply sending to chech better valid
2650 clients. It was possible to send incomplete list of replies.
2652 Fixed the WHOIS and IDENTIFY to send the request to router
2653 if normal server did not do it and did not find any results.
2655 Affected file silcd/command.c.
2657 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * Moved the internal data from SilcClient context into its
2660 own file, not accesible to application. Affected files
2661 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2662 and other files in client library.
2664 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Added doc/examples installation target in Makefile.am.pre.
2669 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2672 commands the found client entry will be removed from the
2673 cache, after notifying application about the error. Affected
2674 file lib/silcclient/command_reply.c.
2676 * Changed the /MSG to check for exact nickname user gave, and
2677 not let `nick' match `nick@host' if it is only one found. Now,
2678 user must type the exact nickname (like nick@host2) even if
2679 there are no more than one same nicks found. This is to avoid
2680 a possibility of sending nickname to wrong nickname since
2681 `nick' could match `nick@host'. Affected file is
2682 irssi/src/core/silc-servers.c.
2684 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Do not print "you are now server operator" or similar when
2687 giving /away command. Affected files are
2688 irssi/src/silc/core/client_ops.c, silc-servers.h.
2690 * Made the silc_server_command_pending_error_check to send
2691 the same command reply payload it received back to the
2692 original sender of the command. This way all arguments
2693 that was received by the server will be received by the
2694 client too. Affected file silcd/command.c.
2696 * Added the silc_idcache_add to return the created cache entry
2697 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2699 * Add global clients to expire if they are not on any channel.
2700 This is because normal server will never know if they signoff
2701 if they are not on any channel. The cache expiry will take
2702 case of these entries. This is done by normal servers only.
2703 The affected files are silcd/command_reply.c,
2704 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2706 * If server receives invalid ID notification for WHOIS or
2707 IDENTIFY and the ID exists in the lists, it is removed.
2708 Affected file silcd/command_reply.c.
2710 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2711 in client then client entry that it matches is searched and
2712 the nickname is printed on the screen for user. Affected
2713 file irssi/src/silc/core/client_ops.c.
2715 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Use cache entry expire time in the LIST command reply to
2718 purge old entries from the cache after the LIST command
2719 reply has been received. This way we don't have non-existent
2720 entries in the cache for too long. Affected file is
2721 silcd/command_reply.c.
2723 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * If we are normal server, and we've not resolved client info
2726 in WHOIS or IDENTIFY from router, and it is global client,
2727 we'll check whether it is on some channel. If it is not
2728 then we cannot be sure about its validity and will resolve it
2729 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2730 file silcd/command.c.
2732 * Search channel by name (if possible) rather than by ID
2733 in IDENTIFY command's command reply. Affected file is
2734 silcd/command_reply.c.
2736 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2739 Updated specs and implemented it. Affected file silcd/command.c,
2740 silcd/packet_send.c and silcd/packet_receive.c.
2742 * Implemented the <founder auth> payload handling in the JOIN
2743 command. If provided all conditions for channel joining
2744 except requirement to provide correct passphrase can be
2745 overrided by the channel founder. Updated the protocol specs.
2746 Affected file silcd/command.c.
2748 Added support for founder auth in JOIN command in client
2749 library. Fixed the parsing of the JOIN command now to support
2750 all options as they should be. The affected file is
2751 lib/silcclient/command.c.
2753 * Optimized the WHOIS and IDENTIFY commands to send the request
2754 to router only if it includes nicknames or other names. If
2755 they include only IDs then check the local cache first before
2756 routing. Affected file is silcd/command.c.
2758 * Added channels topic announcements. Affected file is
2759 silcd/packet_receive.c and silcd/server.c.
2761 * Fixed the silc_server_send_notify_topic_set to really destine
2762 the packet to channel. Affected file silcd/packet_send.c.
2764 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2765 library. Affected file lib/silcclient/client_notify.c.
2767 * Added UMODE announcements. Affected file silcd/server.c.
2769 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Memory leak fixes in:
2773 lib/silcutil/silcsockconn.c
2774 lib/silcske/silcske.c
2775 lib/silcske/groups.c
2777 lib/silccrypt/silcpkcs.c
2778 lib/silccore/silccommand.c
2779 lib/silccore/silcidcache.c
2784 * ROBOdoc documented the lib/silcske/groups.h file and a
2785 bit changed the interface for better.
2787 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2789 * Update the client entry context in the ID cache after
2790 nick change. Affected file lib/silcclient/command.c.
2791 Fixes the CUMODE command when regaining founder privileges,
2792 and a little WHOIS problem.
2794 * Fixed silc_net_gethostbyname to correctly call the
2795 inet_ntop. Affected file lib/silcutil/silcnet.c.
2797 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2799 * Added IPv6 support checking to the configure.in.pre, added
2800 also --enable-ipv6 option to override the check. Affected
2801 file configure.in.pre.
2803 * The silc_thread_create now calls the start function
2804 directly if threads support is not compiled in. Removes
2805 ugly #ifdef's from generic code. Affected files are
2806 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2808 * Added silc_net_gethostby[name/addr]_async to asynchronously
2809 resolve. Affected files are lib/silcutil/silcnet.[ch].
2811 * Added support for rendering IPv6 based server, client and
2812 channel IDs. Affected file lib/silcutil/silcutil.c.
2814 * Added support for creating IPv6 based server IDs. Affected
2815 file is silcd/serverid.c.
2817 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2819 * Added silc_net_gethostby[addr/name] into the
2820 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2821 routines. Added silc_net_is_ip[4/6]. Affected file is
2822 lib/silcutil/unix/silcunixnet.c. All routines that take
2823 address as argument now supports both IPv4 and IPv6 addresses.
2825 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2827 * Fixed LIST command reply sending in server. Affected file
2830 * Server now sends the kicker's client ID in the KICK notify
2831 to the kicked client. Affected file silcd/command.c.
2833 * The client library now parses the kickers client ID and
2834 UI displays it. Affected files lib/silcclient/client_notify.c
2835 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2837 * Made all payload parsing function prototypes consistent.
2838 They all take now const unsigned char * and uint32 pair as
2839 the payload data instead of SilcBuffer. Changes all around
2840 the source tree. Other unsigned char* -> const unsigned char*
2841 changes around the tree as well.
2843 * Optimized SFTP client and server packet sending not to
2844 allocate new buffer for each packet but to recycle the
2845 first allocated buffer. Affected files are
2846 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2848 * Optimized the SFTP client to use SilcList instead of
2849 SilcDList for requests, because it is faster. Affected file
2850 is lib/silcsftp/sftp_client.c.
2852 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2853 into lib/silccore/silcid.[ch].
2855 Renamed silcpayload.[ch] into silcargument.[ch].
2857 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2859 * If client entry is deleted with active key agreement
2860 session, abort the session.
2862 The silc_client_abort_key_agreement now calls the completion
2863 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2865 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2868 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Don't use __restrict in older GCC's. Affected file is
2871 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2873 * silc_net_localhost now attempts to reverse lookup the
2874 IP/hostname. Affected file lib/silcutil/silcnet.c.
2876 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2877 command. It can be used to gain founder privileges at
2878 the same time when joining the channel.
2880 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2881 kicker's client ID as well. Updated protocol specs.
2883 Defined that the server must send SILC_COMMAND_IDENTIFY
2884 command reply with error status to client who sent
2885 private message with invalid client ID.
2887 Updated the protocol specification.
2889 * Added silc_server_send_command_reply to send any
2890 command reply. Affected file silcd/packet_send.[ch].
2892 * Added silc_id_payload_encode_data to encode ID payload
2893 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2895 * The server now send IDENTIFY command reply with error
2896 status if client ID in private message is invalid. Affected
2897 file silcd/packet_receive.c.
2899 * Save the server key file with server's IP address in
2900 the filename instead of hostname. The affected file is
2901 irssi/src/silc/core/client_ops.c.
2903 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2908 * Added libtool support for compiling shared objects in
2909 lib/silcsim. Affected file configure.in.pre and
2910 lib/silcsim/Makefile.am. Original patch by cras.
2912 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Pid file configuration, and server's config file fixes
2915 patch by toma. Updated CREDITS file.
2917 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Fixed silc_client_channel_message to not try to decrypt
2920 the message twice if it resolved the destination client
2921 information. This could cause of dropping one channel
2922 message. Affected file lib/silcclient/client_channel.c.
2924 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2927 lib/silcclient/client.c. This function is used when the SILC
2928 Client is run under some other scheduler, or event loop or
2929 main loop. On GUI applications, for example this may be
2930 desired to used to run the client under the GUI application's
2931 main loop. Typically the GUI application would register an
2932 idle task that calls this function multiple times in a second
2933 to quickly process the SILC specific data.
2935 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2937 * Fixed silc_server_drop() for dropping the supplementary
2938 groups as well, this could cause a security hole on some
2941 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2946 * Write PID file after dropping privileges. Added -F option
2947 to run server on foreground. A patch by debolaz.
2948 Affected files silcd/server.c, silcd/silcd.c.
2950 * Fixed MOTD to return the MOTD file server name. Affected
2951 file silcd/command.c.
2953 * Added INFO command reply handling to the Irssi SILC Client.
2954 Affected file irssi/src/silc/core/client_ops.c.
2956 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Fixed the silc_idcache_list_* routines to really support
2959 the dynamic list. Fixes a crash. Affected file is
2960 lib/silccore/silcidcache.c.
2962 * Fixed the LIST command reply to really call LIST command's
2963 pending callbacks. Affected file silcd/command_reply.c.
2965 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Update conn->local_entry->nickname after giving NICK
2968 command. Affected file lib/silcclient/command.c.
2970 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2972 * Added the [pid] option to the silcd configuration file
2974 Affected files: serverconfig.[ch] and silcd.c
2976 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Save fingerprint in WHOIS command reply in server.
2979 Affected file silcd/command_reply.c.
2981 * Fixed NICK commands pending callback registration.
2982 Affected file lib/silcclient/command.c.
2984 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Use ++server->cmd_ident when sending commands in server,
2987 instead of random number. Affected file silcd/command.c.
2989 * Fixed GETKEY command reply to call actually GETKEY pending
2990 command callbacks. Affected file silcd/command_reply.c.
2992 * A bit stricter check for nicknames. Check for same nickname
2993 in NICK command also. Affected file silcd/command.c.
2995 * Do not call INFO command everytime client ID changes, only
2996 during first connecting. Affected file lib/silcclient/client.c.
2998 * Set the new nickname only after successful command reply for
2999 NICK command is returned by server. Affected file
3000 lib/silcclient/command.c.
3002 * Remove nicknames from nicklist during server_signoff notify.
3003 Should fix /NAMES bit more. The affected file is
3004 irssi/src/silc/core/silc-channels.c.
3006 * Added `fingerprint' field to the SilcIDListData in the
3007 silcd/idlist.h to hold the fingerprint of the client's
3010 Send the fingerprint of the client's public key in WHOIS
3013 Affected files silcd/command.c, and silcd/idlist.[ch].
3015 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3016 create fingerprint from given data.
3018 * Show the fingerprint of the client's public key in WHOIS.
3019 Affected files irssi/src/module-formats.[ch] and
3020 irssi/src/silc/core/client_ops.c.
3022 * Format the multiple same nicknames also during JOIN and
3023 NICK_CHANGE notifys. Affected file is
3024 lib/silcclient/client_notify.c.
3026 * Do not print error on screen for invalid private message
3027 payload since it can come if someone is sending private
3028 messages with wrong key. Affected file
3029 lib/silccore/silcprivate.c.
3031 * Fixed multiple concurrent /PING crash. Affected file
3032 lib/silcclient/command.c.
3034 * Changed the wrong ID encoding. All IP addresses must be
3035 in MSB first order in encoded format. They were encoded
3036 wrong and was in LSB format. Affected files are
3037 silcd/serverid.c, lib/silcutil/silcutil.c.
3039 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3041 * Call the `connect' client operation through the scheduler
3042 in case of error. Affected file lib/silcclient/client.c.
3044 * Call the `failure' client operation even if the error
3045 occurred locally during a protocol. Affected file is
3046 lib/silcclient/protocol.c.
3048 * Added support of sending LIST command to router from normal
3049 server. This way normal server can get list of all channels
3050 in the network too. Fixed the channel list sending in the
3051 server too. Affected files are silcd/command.c, and
3052 silcd/command_reply.[ch].
3054 * Added silc_server_update_channels_by_server and
3055 silc_server_remove_channels_by_server. They are used during
3056 disconnection of primary router and in backup router protocol.
3057 Affected file silcd/server_util.[ch], silcd/server.c and
3058 silcd/server_backup.c.
3060 * Fixed channel adding to global list in IDENTIFY command
3061 reply in server. Affected file silcd/command_reply.c.
3063 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * If the incoming packet type is REKEY or REKEY_DONE process
3066 that packet always synchronously. Fixes yet another MAC
3067 failed error on slow (dialup) connections. Affected file
3068 lib/silcclient/client.c and silcd/server.c.
3070 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Call check_version SKE callback for initiator too. Affected
3073 file lib/silcske/silcske.c.
3075 * Implemented fix for security hole found in the SKE that was
3076 fixed in the specification few days back; the initiator's
3077 public key is now added to the HASH value computation.
3078 Added backwards support for the old way of doing it too, for
3079 old clients and old servers. Affected file is
3080 lib/silcske/silcske.c.
3082 * Enabled mutual authentication by default in SKE. If initiator
3083 is not providing mutual authentication the responder will
3084 force it. This will provide the proof of posession of the
3085 private key for responder. The affected files are
3086 lib/silcclient/protocol.c and silcd/protocol.c.
3088 * Do not cache anymore the server's public key during SKE.
3089 We do mutual authentication so the proof of posession of
3090 private key is done, and if the server is authenticated in
3091 conn auth protocol with public key we must have the public
3092 key already. Affected file silcd/protocol.c.
3094 * Added new global debug variable: silc_debug_hexdump. If
3095 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3096 file lib/silcutil/silclog.[ch].
3098 * Fixed compilation warning due to char * -> const char *.
3099 Affected files lib/silcutil/silcnet.h, and
3100 lib/silccore/silcauth.[ch].
3102 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Fixed CMODE command when new channel key was created. If
3105 the creation failed the old key was removed. Next time giving
3106 same command would crash the server since the old key was
3107 freed already. Affected file silcd/command.c.
3109 * Fixed the silc_server_announce_get_channels to not crash
3110 on reconnect. Affected file silcd/server.c.
3112 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Added silc_log_set_debug_string function to set a regex
3115 string to match for debug output. Only the function names,
3116 or filenames matching the given debug string is actually
3117 printed. This way it is possible to filter out those debug
3118 strings that user is not interested in.
3120 Fixed a bug in silc_string_regexify.
3122 Affected files lib/silcutil/silclog.[ch], and
3123 lib/silcutil/unix/silcunixutil.c.
3125 * Changed the -d options in both server and Irssi SILC client
3126 to take the debug string as argument. Affected files
3127 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3129 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3131 * Added silc_hash_babbleprint to create a Bubble Babble
3132 Encoded fingerprint. The encoding is developed by Antti
3133 Huima (draft-huima-babble-01.txt), and it creates human
3134 readable strings out of binary data. Affected file
3135 lib/silccrypt/silchash.[ch].
3137 * Print the babble print now in addition of fingerprint as well
3138 in Irssi SILC client. Affected files are
3139 irssi/src/fe-common/silc/module-formats.[ch],
3140 irssi/src/fe-common/silc/core/client_ops.c.
3142 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * Fixed a security problem found in SKE. The initiator's
3145 public key too is now added to the HASH hash value creation
3146 which is signed by the responder to create the SIGN value.
3147 This will prevent anyone in the middle to lie to the responder
3148 about the initiator's public key. If this is done now, the
3149 man in the middle will get caught. Updated the protocol
3152 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>

3188 * Added silc_pkcs_public_key_compare to compare two
3189 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3191 * Check that the client who set the founder mode on the
3192 channel is the same client that is giving the founder
3193 mode to itself. It is done by comparing the saved public
3194 key (it is saved even in the authentication is passphrase).

3202 * Process the DISCONNECT packet through scheduler in the
3203 client library. Affected file lib/silcclient/client.c.
3205 * Fixed the silc_client_packet_parse to not to increase
3206 the packet sequence number if the conn->sock and the
3207 current socket connection is not same. This can happen
3208 for example during key agreement when the conn includes
3209 multiple socket connections (listeners). Affected file
3210 lib/silcclient/client.c.
3212 * The sender of the file transfer request now provides also
3213 the pointer (listener) for the key exchange protocol. If
3214 the listener cannot be created then it sends empty key
3215 agreement and lets the receiver provide the listener.
3217 Added `local_ip' and `local_port' arguments to the
3218 silc_client_file_send. If they are provided they are used,
3219 if not then it will attempt to find local IP address, if
3220 not found or bind fails then the remote client will provide
3223 Affected files are lib/silcclient/client_ftp.c and
3224 lib/silcclient/silcapi.h.

3233 of the client's public key (if the proof of posession of the
3234 corresponding private key is verified by the server).
3235 Updated to the protocol specification.
3237 * Added support of receiving the client's public key's
3238 fingerprint in command reply in client library. Affected
3239 file is lib/silcclient/command_reply.c, and
3240 lib/silcclient/idlist.[ch].

3299 preserve the WHOWAS info for the client. Affected file
3300 silcd/server_util.c.
3302 * Fixed SERVER_SIGNOFF notify handling in the server. The
3303 server is now able to process incoming SERVER_SIGNOFF notify
3304 for a server that it doesn't even know about. It will remove
3305 the clients provided in the notify. Affected file
3306 silcd/packet_receive.c.
3308 * Check for partial packet in data queue after every packet that
3309 was found from the queue. Return and wait for more data if
3310 there is partial data in queue. Affected file is
3311 lib/silccore/silcpacket.c.
3313 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3328 irssi/src/fe-common/silc/module-formats.[ch].
3330 * Wrote a help file for FILE command.
3332 * Added silc_rng_global_get_byte_fast to get not-so-secure
3333 random data as fast as possible. Random data is read from
3334 /dev/urandom if available and from the SILC RNG if not
3335 available. It is used in padding generation. Affected file
3336 lib/silccrypt/silcrng.[ch].
3338 * All packets in client library are now processed synchronously.
3339 Optimized packet processing a lot. Affected file
3340 lib/silcclient/client.c.
3342 * All server connection packets are processing synchronously
3343 now in server, to optimize packet processing. Affected file
3346 * Include files are installed now only in Toolkit distribution
3347 if make install is given. Affected files: all Makefile.am's.
3349 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Assure that silc_client_notify_by_server_resolve does not
3352 resolve the client information multiple times. If it cannot
3353 be found by the first it cannot be found at all. Affected
3354 file lib/silcclient/client_notify.c.
3356 * Fixed WHOWAS command reply calling. Affected file
3357 lib/silcclient/command_reply.c.
3359 * Removed all references to silc_idlist_get_client from the
3360 Irssi SILC client since that call is internal call used by
3361 the library. The Irssi SILC client will use now client
3362 retrieval functions found in silcapi.h.
3364 * Fixed a bug in resolving nickname info before sending
3365 private message. It used freed memory. Affected file
3366 irssi/src/silc/core/silc-servers.c.

3387 * Added silc_net_localip to return local host's IP address.
3388 Affected file lib/silcutil/silcnet.[ch].
3390 * If key exchange or rekey protocol is active for a connection
3391 parse all packets syncronously since there might be packets
3392 in packet queue that we are not able to process without first
3393 processing packets before them. Affected file silcd/server,
3394 lib/silcclient/client.c.
3396 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3397 whether library should continue processing the packet.
3398 Affected file lib/silccore/silcpacket.h.
3400 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3444 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3445 is incomplete and is being resolved, it won't be resolved
3448 Make sure also that USERS command reply does not resolve
3449 twice information. Affected file is
3450 lib/silcclient/command_reply.c.
3452 Make sure that silc_client_get_clients_by_list does not
3453 resolve twice same information.
3455 * Check for valid client->id in the silc_server_free_client_data.
3456 Affected file silcd/server.c.
3458 * Fixed /GETKEY nick@server not to crash if the server entry
3459 is not found. Affected file lib/silcclient/command.c.

3471 * Call the silc_server_udpate_servers_by_server in the
3472 primary router that comes back online in the backup resuming
3473 protocol. Otherwise it routes packets wrong. Affected file
3474 silcd/server_util.[ch], silcd/server_backup.c.
3476 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3479 lib/silcutil/silcbuffmt.[ch].
3481 * Redefined the SILC packet header to include the padding
3482 length. Affected file lib/silccore/silcpacket.[ch].
3484 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3485 length for maximum padding up to 128 bytes). Affected
3486 file lib/silccore/silcpacket.h.
3488 * Removed all backwards support for old 0.5.x MAC thingies.
3489 The SILC packet header change makes it impossible to be
3490 backwards compatible.
3492 * Send the ENDING packet with timeout in the backup resuming
3493 protocol. This is to assure that all routers has connected
3494 to the primary router. Affected file silcd/server_backup.c.
3496 * Changed the RNG to take the first IV from random data. It
3497 used to take it from zero actually. Changed the RNG also
3498 to use /dev/urandom during session. /dev/random is used
3499 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3501 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3504 (the packet length) encrypted. Affected files aroung the
3505 code tree, lib/silccore/silcpacket.[ch]. Removed the
3506 SilcPacketCheckDecrypt callback. It is not needed anymore
3507 since the silc_packet_receive_process will determine now
3508 whether the packet is normal or special.
3510 * Implemented the unidirectional MAC keys. Affected files
3511 lib/silcske/silcske.c, silcd/protocol.c and
3512 lib/silcclient/protocol.c.

3519 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3521 * Allow backup router to announce servers. All servers
3522 announced by backup router are added to the global list
3523 automatically. Update hte server's socket to our primary
3524 router also when backup router announces a server.
3525 Affected file silcd/packet_receive.c.
3527 * Do not update the client->router in the function
3528 silc_server_udpate_clients_by_server if the client is on
3529 global list. We might fail to find any specific server
3530 for locally connected clients and local cell clients. They
3531 should still use the `from' and not `to' as client->router.
3532 This fixes backup router resuming protocol. Affected file
3533 silcd/server_util.c.
3535 * Decrease channel statistics count only if the channel
3536 deletion worked. Affected files are silcd/server.c and
3537 silcd/server_util.c.
3539 * Added silc_server_update_servers_by_server to update origin
3540 of all server entries. Used during backup router protocol.

3552 to the sender. Affected file silcd/packet_receive.c.
3554 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3556 * Made better checks that the channel message is not sent
3557 to the router it came from. Affected file is
3558 silcd/packet_send.c. Fixed memory leak too.
3560 * Announce informations for incoming router connection, but
3561 only after checking if it is replaced by backup router.
3562 Affected file silcd/packet_receive.c.
3564 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3567 router environment. Affected file silcd/server_backup.c.
3569 * Route packet only to one router in the function
3570 silc_server_packet_send_to_channel. Affected file is
3571 silcd/packet_send.c.
3573 * Fixed silc_server_send_notify_dest to set the broadcast
3574 flag. Fixed the silc_server_send_notify_topic to actually
3575 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3576 Affected file silcd/packet_send.c.
3578 * Changed the SFTP Filesystem interface. Changed the
3579 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3580 the filesystem operation function. The SilcSFTPFilesystem
3581 is now a context that is allocated by all filesystem allocation
3582 functions and it already includes the operations structure
3583 and filesystem specific context. It is given as argument
3584 now to the silc_sftp_server_start. This made the interface
3585 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3586 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3588 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * Changed the backup router adding and getting interfaces
3591 in the server. The router that will be replaced by the
3592 specified backup router is now sent as argument. Affected
3593 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3596 * Added silc_net_addr2bin_ne to return the binary form of
3597 the IP address in network byte order. Affected files

3613 * Wrote the definition of the backup resuming protocol to the
3614 protocol specification.
3616 * Removed one redundant channel key generation from normal
3617 server during joining procedure. Removed one redundant
3618 channel key sending from server to router during joining
3619 procedure. Affected file silcd/command.c.
3621 * Made minor bugfixes to the backup router resuming protocol.
3622 Affected file silcd/server_backup.c, server.c.

3645 send any data. Affected file lib/silcclient/client.c.
3647 * Implemented the backup router support when the primary router
3648 goes down. The servers and routers can now use the backup
3649 router as new primary router without loosing connectivity.
3651 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3653 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3654 in the server to indicate disabled entry. All data read
3655 from the connection will be ignored and no data is sent
3656 for entry that is disabled. Affected files are
3657 silcd/idlist.h, silcd/server.c.
3659 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3667 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3670 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Implemented the SFTP (SSH File Transfer Protocol) to the
3673 lib/silcsftp. It includes SFTP client and SFTP server
3676 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * Moved lib/silccore/silcprotocol.[ch] to the
3679 lib/silcutil library.
3681 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3682 take variable argument list pointer as argument. Affected
3683 file lib/silcutil/silcbuffmt.[ch].
3685 * Added silc_buffer_set function that is used to set data
3686 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3687 Affected file lib/silcutil/silcbuffer.h.
3689 * Changed various routines in the core library to use the new
3690 silc_buffer_set instead of allocating new buffer only for
3693 * Added 64-bit value formatting and unformatting support to the
3694 silc_buffer_[un]format routines. Affected file is
3695 lib/silcutil/silcbuffmt.[ch].
3697 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3698 to includes/bitmove.h.
3700 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * Fixed channel user mode saving in client library. Affected
3703 file lib/silcclient/command[_reply].c.
3705 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * Defined the file transfer to the SILC Protocol. Added
3708 new packet type SILC_PACKET_FTP and defined File Transfer
3709 Payload. The mandatory file transfer protocol is SFTP
3710 (SSH File Transfer Protocol). Affected file in addition
3711 of the internet draft is lib/silccore/silcpacket.h.
3713 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3714 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3715 is used as part of backup router protocol when the primary
3716 router of the cell is back online and wishes to resume
3717 the position as primary router.
3719 * Redefined the MAC generation keys in the protocol. The
3720 same key is not used anymore in both direction. Both
3721 direction will now use different keys for sending and
3722 receiving. This fixes a potential security flaw. This
3723 change causes incompatibilities in the protocol.
3725 * Redefined also the MAC computation from the packet.
3726 An packet sequence number is now added to the MAC
3727 computation. This prevents possible replay attacks against
3728 the protocol. This change too causes incompatibilities
3731 Added `sequence' field to the SilcPacketContext to hold
3732 the current sequence number for the packet.
3734 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3736 * Added `created' field to the SilcIDListData in the file
3737 silcd/idlist.h to indicate the time when the entry was
3740 * Added `created' field to the SilcChannelEntry too. Affected
3741 file silcd/idlist.h.
3743 * Added `creation_time' aguments to all the announcement functions
3744 in the server. If it is provided then only the entries that
3745 was created after the provided time frame are actually
3746 announced. Affected file silcd/server.[ch].
3748 * The protocol says that the Channel ID's IP address must be
3749 based on the router's IP address. Added check for this in
3750 the silc_server_new_channel when processing incoming New Channel
3751 Payload. Affected file silcd/packet_receive.c.
3753 * Print out the correct version with --version in SILC client.
3754 Affected file irssi/src/silc/core/silc-core.c.
3756 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3758 * Fixed WHOWAS command to check for completnes of the client
3759 entry always, not just when the command is coming from client.
3760 Affected file silcd/command.c.
3762 * Added new function silc_server_packet_queue_purge to purge the
3763 outgoing data queue to the network. After the function returns
3764 it is guaranteed that the outgoing packet queue is empty.
3765 Affected file silcd/packet_send.[ch].
3767 * Purge the outgoing packet queue in the rekey protocol's final
3768 callback to assure that all rekey packets go to the network
3769 before quitting the protocol. Affected file silcd/server.c.
3771 * Added silc_client_packet_queue_parse as similar function as
3772 in server to the client library. The affected file is
3773 lib/silcclient/client.c.
3775 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Splitted silcd/server.c and created silcd/server_util.[ch]
3778 for utility functions.
3780 * Added new socket flag SILC_SF_DISABLED to indicate that the
3781 connection is open but nothing can be sent to or received from
3782 the connection. Affected file lib/silcutil/silsockconn.[ch].
3783 The checking for disabled socket is checked in the low level
3784 silc_socket_write and silc_socket_read functions.
3786 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3788 * Allow only nicknames and channel names that fits into the
3789 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3791 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3793 * When processing JOIN command reply in server check that if
3794 the channel exists in our global list we'll move it the local
3795 list. Affected file silcd/command_reply.c.
3797 * Fixed the check whether client is joined on the channel already
3798 in JOIN command. Affected file lib/silcclient/command.c.
3800 * Fixed the JOIN command reply to check whether the channel
3801 already exists. Affected file lib/silcclient/command_reply.c.
3803 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3805 * Added silc_ske_status_string to map the SKE error numbers
3806 to readable strings. The affected files are
3807 lib/silcske/silcske[_status].[ch].
3809 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Do not show the private channels on the WHOIS channel list
3812 as it is not allowed by the protocol. The affected file is
3815 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3817 * Assure that the packet length digged from the actual packet
3818 is something sensible in the silc_packet_decrypt_rest_special
3819 in lib/silccrypt/silcpacket.c.
3821 * Free and NULL the allocated pointer in silc_hmac_alloc if
3822 the HMAC allocation fails. The affected file is
3823 lib/silccrypt/silchmac.c.
3825 * Print the selected security properties to the log files in
3826 the server. Affected file silcd/protocol.c.
3828 * Add SKE's reference counter even if calling the completion
3829 callback manually. Otherwise it goes negative, although it
3830 does not cause any problems. The affected file is
3831 lib/silcske/silcske.c.
3833 * Remove the client entry with short timeout after giving the
3834 KILL command. Affected file lib/silcclient/command.c.
3836 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3837 case all found clients are already disconnected (WHOWAS would
3838 found them) in the server. Affected file silcd/command.c.
3840 * Update the last_receive (time of last data received) to be
3841 updated only when received private or channel message so that
3842 the idle time showed in WHOIS makes more sense.
3844 * Added boolean field `valid' in to the SilcClientEntry in the
3845 client library to indicate whether the entry is valid or not.
3846 This fixes the nickname change bug on channel when changing
3847 the nickname to be same than the old (like nick to Nick) the
3848 nickname formatter doesn't set the new nick anymore to Nick@host.
3849 Affected file lib/silcclient/idlist.[ch].
3851 * Now actually fixed the nickname changing on disconnection.
3852 Added new function silc_change_nick to the Irssi SILC Client.
3853 Affected file irssi/src/silc/core/client_ops.c,
3854 irssi/src/silc/core/silc-nicklist.[ch].
3856 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3858 * Check that the public key exists in the GETKEY command before
3859 trying to encode it. Affected file silcd/command.c.
3861 * Print some notifications on received public keys with GETKEY
3862 command in the Irssi SILC Client. Affected files are
3863 irssi/src/fe-common/silc/module-formats.[ch],
3864 irssi/src/silc/core/client_ops.c.
3866 * Use IDENTIFY command to resolve the server information in the
3867 GETKEY command instead of INFO command. Affected file
3868 lib/silcclient/command.c.
3870 * All command reply functions in the client library now calls
3871 the pending command reply callbacks even if an error has
3872 occurred. The server has done this a long time and now it was
3873 time to move the client library to this as well. Now all
3874 errors can be delivered back to the pending command reply
3875 callbacks if necessary. Affected files are
3876 lib/silcclient/command[_reply].[ch].
3878 * Change the nickname on disconnection back to the username
3879 because in reconnect the server will enforce it to it anyway.
3880 Affected file irssi/src/silc/core/silc-servers.c.
3882 * Fixed a config file parsing bug in the Irssi SILC client.
3883 Affected file irssi/src/silc/core/clientconfig.c.
3885 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3887 * When printing the channel mode on JOIN, verify that the
3888 channel key and channel's HMAC are valid. Affected file
3889 irssi/src/silc/core/client_ops.c.
3891 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3893 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3894 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3895 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3897 * Removed channel key rekey task deleting from the function
3898 silc_server_save_channel_key. Affected file silcd/server.c.
3899 Added explicit timeout task context instead that is used to
3900 delete the task if we are registering a new task before the
3901 new task has elapsed.
3903 * When channel key rekey occurs the client library now saves
3904 the old channel key for a short period of time (10 seconds) and
3905 is able to use it in case some is still sending channel
3906 messages encrypted with the old key after the rekey. Affected
3907 file lib/silcclient/[idlist.h|client_channel.c].
3909 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3911 * Added check to the silc_server_new_id_real to not accept
3912 new ID if it is the sender's own ID. Affected file is
3913 silcd/packet_receive.c.
3915 * Assure that we do not announce ourself or the one we've
3916 sending our announcements when we're router and are announcing
3917 servers to our primary router. Affected file silcd/server.c.
3919 * Fixed silc_server_command_identify_check_client to assemble
3920 correct WHOIS packet. It send corrupted WHOIS packet and
3921 caused problem with router to router connections. Affected
3922 file silcd/command.c.
3924 Fixed also silc_server_command_whois_check the same way
3925 as for the IDENTIFY command.
3927 * Added new SilcIDListStatus to the server in the SilcIDListData
3928 structure. The status now includes the current status of
3929 the entry (like registered, resolved etc.). Affected file
3930 silcd/idlist.[ch]. Defined a bunch of different status types
3931 as well. This replaced the old boolean registered field as well.
3933 Added resolve_cmd_ident field to the SilcClientEntry structure
3934 too so that if the entry is for example being resolved so
3935 another command may attach to the same pending command reply
3936 without requiring to resolve the same entry again. This concept
3937 should optimize the WHOIS and the IDENTIFY resolving under
3938 heavy load by taking away unnecessary resolving for entries
3939 that are being resolved already.
3941 Added support for adding multiple pending commands for one
3942 command idenfier. Affected file silcd/command[_reply].[ch].
3944 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3945 before deleting the data. Otherwise the hash table will have
3946 freed data in comparison functions. Affected file is
3947 silcd/command_reply.c.
3949 * Fixed silc_idlist_replace_client_id to add the new entry to
3950 the cache with NULL nickname. Otherwise there will be invalid
3951 memory as the nickname after the nickname is freed. Affected
3952 file silcd/packet_receive.c.
3954 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3955 saved into wrong slots because the previous number of entries
3956 was not taken into account. Affected file silcd/idlist.c.
3957 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3959 * If we are router and we receive JOIN notify to a channel that
3960 does not have any users then notified client is marked as the
3961 channel founder, as it is it. The affected file is
3962 silcd/packet_receive.c
3964 * Added to the extended hash table API's table_del_*ext functions
3965 the destructor as argument too, so that the caller can decide
3966 which destructor to use or whether to use destructor at all.
3967 Affected file lib/silcutil/silchashtable.[ch].
3969 * Fixed ID Cache purging. It actually deleted the entries from
3970 the hash table after the data was freed. The hash table ended
3971 up comparing freed memory. The affected file is
3972 lib/silccore/silcidcache.c.
3974 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3976 * Fixed Irssi SILC client's KILL command's HELP syntax.
3978 * The USERS command now resolves the detailed user information
3979 if the userinfo field is missing. Affected file is
3980 lib/silcclient/command_reply.c.
3982 * Do not print error in silc_file_read if the read file does
3983 not exist. Just silently return NULL. Affected file is
3984 lib/silcutil/silcutil.c.
3986 * Fixed the silc_log_output to not wine about NULL filename
3987 and to not create some bogus " " filename. Affected file is
3988 lib/silcutil/silclog.c.
3990 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3992 * Fixed various printing bugs on the user interface in the
3993 Irssi SILC Client. Minor changes that were forgotten from
3996 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Fixed the configure.in.pre and the compilation and distribution
3999 environment to support the new autoconf 2.52. That version is
4000 now required to compile the CVS trunk.
4002 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4004 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4005 to generally parse user@fqdn format strings. Affected file
4006 lib/silcutil/silcutil.c.
4008 * Added nickname_format and nickname_force_format fields to the
4009 SilcClientParams structure. The first one defines the format
4010 for the nicknames that the library will enforce if the receives
4011 multiple same nicknames. The second one is boolean value and
4012 can be used to force the library to always enforce the format
4013 to the nicknames regardles whether there are multiple nicknames
4014 or not. This configurable formatting was employed to flexibly
4015 support accessing multiple nicknames from the user interface.
4016 The userinterface can now set the nicknames to what ever format
4017 they prefer. Affected file lib/silcclient/silcapi.h.
4019 Added function silc_client_nickname_format to the file
4020 lib/silcclient/idlist.c. It performs the nickname formatting.
4022 Added new field `hostname´ to the SilcClientEntry context.
4023 It holds the hostname of the client. Affected file is
4024 lib/silcclient/idlist.h.
4026 * Irssi SILC Client sets the nicknames in nick@hostn format.
4027 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4028 irssi/src/silc/core/silc-core.c.
4030 The WHOIS printing now also shows both the real nickname and
4031 the formatted nickname so that user knows how to access the
4032 user if there are multiple same nicknames cached. Affected
4033 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4034 printing formatting too to take the hostname now as a separate
4035 argument. The Affected file is
4036 irssi/src/fe-common/silc/modules-formats.[ch].
4038 * Changed the silc_client_get_clients_local to accept the formatted
4039 nickname as argument. It accepts the real nickname too but the
4040 formatted nickname can be used to find the true entry from
4041 multiple entries. Affected file lib/silcclient/silcapi.h and
4042 lib/silcclient/idlist.c.
4044 * Added nickname_format_parse field to the SilcClientParams.
4045 It is a callback function provided by the application to parse
4046 the nickname out of the formatted nickname string. The library
4047 calls it to get the nickname from the formatted string. Since
4048 the application generally knows better the format of the nickname
4049 string it parses it instead of the library, even though library
4050 encodes the formatted string. If the callback function is not
4051 provided then the library will use the string as is. The
4052 affected file is lib/silcclient/silcapi.h.
4054 * All the nickname strings passed to the client library in
4055 commands are now expected to be formatted nickname strings.
4056 If the command does not support the formatted nickname string
4057 it will assume that the sent string is the actual nickname.
4058 Affected file lib/silcclient/command.c.
4060 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Added public key authentication support to OPER and SILCOPER
4063 commands in the client library. Affected file is
4064 lib/silcclient/command.c.
4066 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4068 * Changed the get_auth_methdod client operation to be asynchronous.
4069 It can be async if the application resolves the authentication
4070 method from the server during the negotiation. Added new
4071 SilcGetAuthMeth completion callback that the application will
4072 call after resolving the authentication method.
4074 Added function silc_client_request_authentication_method that
4075 the application can use to resolve the authentication method
4076 from the server. Added also SilcConnectionAuthRequest callback
4077 that the library will call after the server has replied. The
4078 application can call this function if it does not know the
4079 current authentication method.
4081 Affected files are lib/silcclient/client.c and
4082 lib/silcclient/silcapi.h.
4084 * The Irssi SILC client now automatically resolves the authentication
4085 method incase any configuration information is not present (and
4086 currently there never is). The affected file is
4087 irssi/src/silc/core/client_ops.c.
4089 * Fixed public key authentication from the client library.
4090 Affected file lib/silcclient/protocol.c. Changed also the
4091 protocol specification about the public key authentication in
4092 the connection authentication protocol. The actual data to be
4093 signed is now computed with a hash function before signing.
4095 * Fixed the public key authentication from the server as well.
4096 Affected file silcd/protocol.c.
4098 * Removed the mlock()'s from the memory allocation routines.
4099 Affected file lib/silcutil/silcmemory.c. The ./configure does
4100 not check anymore for the mlock(). Affected file is
4103 * Fixed USERS command in server to allow the execution of the
4104 command for private and secret channels if the client sending
4105 the command is on the channel. Affected file silcd/command.c.
4107 * Fixed silc_client_get_clients_local to return the clients
4108 count correctly. It could return wrong value. Affected file
4109 lib/silcclient/idlist.c.
4111 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4113 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4114 types. The assembler optimizations seemed not to like 64-bit
4115 data types. The assmebler optimizations thus are now enabled
4116 also for BSD systems as opposed to only enable them for Linux.
4118 * Do not check for threads at all on BSD systems. Affected
4119 file configure.in.pre.
4121 * Removed -n and -h options from the Irssi SILC Client since
4122 they are not used in silc.
4124 * Fixed the prime generation to assure that the first digit
4125 of the generated random number is not zero since our conversion
4126 routines does not like number strings that starts with zero
4127 digit. If zero digit is seen the random number is regenerated.
4128 This caused some corrupted RSA keys when the zero first digit
4129 was met. Affected file lib/silcmath/silcprimegen.c.
4131 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4133 * Fixed WIN32 configuration in the ./configure script.
4134 Fixed to include xti.h on environments that has it.
4135 Patches by Carsten Ilchmann and andrew.
4137 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4139 * Changed the silc_id_create_client_id to be collision
4140 resistant. It is now assured that there cannot be created
4141 two same client ID's. I suspect that some weird bugs in
4142 the server were actually caused by duplicate Client IDs.
4143 Affected file silcd/serverid.[ch]. A router receiving
4144 new ID now also assures and informs the sending server
4145 if the ID caused collision.
4147 * Changed the silc_id_create_channel_id to also assure that
4148 there are no collisions.
4150 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4152 * Statement about ignoring the Mutual Authentication flag when
4153 performing rekey with PFS was a bit misleading. It is ignored
4154 if it was set in the initial negotiation, it cannot be even
4155 set in the rekey. Fixed in the ke-auth draft. Started the
4156 new versions of the protocol drafts in the doc/.
4158 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4160 * Fixed a bug in silc_client_command_identify_save when saving
4161 new channel information. The channel name was no duplicated
4162 and caused crash on exit. Affected file is
4163 lib/silcclient/command_reply.c.
4165 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4167 * Fixed the getkey command handling in the server. Send just
4168 empty OK reply to the sender if the key could not be fetched
4169 (but everything else was ok, like the key just was not available).
4170 Changed the public key parameter to optional in the protocol
4171 specs so that empty OK reply can be sent. Affected file
4174 Added a message to Irssi SILC client to tell to user if the
4175 server did not return a public key.
4177 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4179 * Fixed a channel key regeneration bug. It registered new
4180 timeout tasks exponentially until all system resources were
4181 used. Affected file silcd/server.c.
4183 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4185 * Added the SILC Document generator to the scripts/silcdoc.
4186 It can be used to generate the Toolkit Reference Manual out
4187 of the source tree. Internally it will also use the RoboDoc
4188 generator now imported in util/robodoc.
4190 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4192 * Added couple of return's in rekey protocol if error orccurred
4193 during the protocol. The execution must be terminated.
4194 Affected file silcd/protocol.c. Also, terminate the protocol
4195 always with timeout.
4197 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4199 * The client's Client ID was created initally from the wrong
4200 nickname (it could have been in format nick@host) in the
4201 silc_server_new_client. Affected file silcd/packet_receive.c
4203 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Added some SILC_LOG_ERROR's to various error conditions
4206 if client could not be added to ID cache. Affected files
4207 silcd/packet_receive.c and silcd/server.c.
4209 * When client's sock->user_data is freed, NULL also the
4210 client->router and client->connection pointers. Added check
4211 for these pointers being NULL to various places around the
4212 code. Affected file silcd/server.c.
4214 * Added client->data.registered == TRUE checks to various
4215 places around the code to assure that unregistered client's
4216 are not handled when it is not allowed. Affected file
4219 * Added `bool registered' fields to all
4220 silc_idlist_[server|client]_get_* routines to indicate whether
4221 the fetched client needs to be registered or not. Affected
4222 file silcd/idlist.[ch].
4224 * Add your own entry as registered to the ID cache in the
4225 server. Affected file server.c.
4227 * Fixed a bug in silc_server_new_server. The SilcServer was
4228 set as the new server's context instead of SilcServerEntry.
4229 This naturally caused some weird bugs.
4231 * Added "updated" field the SilcChannelEntry which indicates
4232 the time since the channel entry was last accessed. This
4233 can be used to determine whether it is necessary to
4234 announce the channel after backup resuming protocol.
4235 Affected files silcd/idlist.[ch].
4237 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4239 * Do not delete the channel rekey task when adding it
4240 for in silc_server_create_channel_key.
4242 * Changed the silc_server_create_channel_key to return
4243 TRUE or FALSE to indicate the success of the channel key
4246 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4248 * Fixed MSVC++ project files and added missing files to

4251 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4253 * Do not add TCP_NODELAY flag if the operating system
4254 does not have it defined. Affected files are
4255 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4257 * Fixed buffer overflow from Irssi SILC Client. Affected
4258 file irssi/src/fe-common/core/themes.c.
4260 * Fixed double free in client library in the file
4261 lib/silcclient/client.c when disconnecting from server.
4263 * Applied double free patch from cras to Irssi SILC client.
4264 Affected files irssi/src/core/[modules/expandos].c
4266 * Fixed the disconnection handling to Irssi SILC Client.
4267 The application must call silc_client_close_connection
4268 in ops->connect client operation in case of failure of
4269 the connection. Affected file is
4270 irssi/src/silc/core/client_ops.c.
4272 * Do not set sock->protocol to NULL in the function
4273 silc_client_close_connection after executing the protocol's
4274 final callback since the sock might not be valid anymore.
4275 Affected file lib/silcclient/client.c.
4277 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4279 * Do not enable SILC_THREADS if the linking with libpthread
4280 did not happen. Affected file configure.in.pre.
4282 * Added notion to protocol specification that server must
4283 verify the sent authentication payload with CMODE when
4284 setting the channel founder key. Implemented it to the
4285 server. Affected file silcd/command.c.
4287 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4289 * Added _EXTRA_DIST SILC distribution variable to the
4290 distributions file. It is used to conditionally add extra
4291 files or directories to the specific distribution. Affected
4292 files ./prepare, Makefile.am.pre and distributions.
4294 Removed the `_' from the start of the distribution names.
4297 * Added README.WIN32 for instructions to compile the Toolkit
4300 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4302 * Fixed a double free in disconnection in the server. Affected
4303 file is silcd/server.c.
4305 * Fixed the lib/silcske/groups.c to work now also with GMP
4306 MP library. The string conversion did not work when using
4307 specific base and the base is indicated in the string as well.
4309 * Created win32/ directory which now includes MSVC++ specific
4310 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4311 It will appear only in the toolkit distribution
4313 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4315 * Changed the key material distribution function in case when
4316 the hash output is too short. The data is now concatenated
4317 a bit differently than it used to. Made the change to the
4318 SKE protocol specification.
4320 * Added better GMP detection to configure.in.pre. A patch
4323 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4325 * Fixed a minor bug in SKE that might cause some problem on
4326 some platforms. Affected file lib/silcske/silcske.c.
4328 * Added the cookie checking for initiator in the SKE. It checks
4329 that the responder returns the sent cookie unmodified. The
4330 affected file is lib/silcske/silcske.c. Added new SKE
4331 error type INVALID_COOKIE that can be sent during the
4332 negotiation. Fixed some memory leaks as well.
4334 * Added the "invalid cookie" error message to Irssi SILC client's
4337 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Added `task_max' field to the SilcClientParams to indicate
4340 the maximum tasks the scheduler can handle. If set to zero,
4341 default values are used. Affected file lib/silcclient/silcapi.h.
4343 * Fixed memory leaks in silc_client_close_connection. Affected
4344 file lib/silcclient/client.c.
4346 * Added silc_client_del_client_entry to client library to free
4347 all memory of given client entry. Affected file is
4348 lib/silcclient/idlist.[ch].
4350 * Added new functions silc_client_del_channel and
4351 silc_client_del_server to delete channel and server entries.
4352 Affected file lib/silcclient/[silcapi.h/idlist.c].
4354 * Removed silc_client_del_client_by_id from silcapi.h.
4356 * Fixed the INFO command to return the server's own info
4357 correctly when querying by Server ID. Affected file is
4360 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4362 * Removed the non-blocking settings in WIN32 code in the
4363 silc_sock_[read/write] and added SleepEx instead. Affected
4364 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4365 of input data is now checked with FIONREAD and ioctlsocket.
4367 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4369 * Call silc_schedule_task_del_by_context in the
4370 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4371 Affected file lib/silccore/silcprotocol.c.
4373 * Call silc_protocol_cancel for active protocols in the
4374 silc_server_close_connection if the funtion
4375 silc_server_free_sock_user_data has not been called.
4376 Affected file silcd/server.c.
4378 * Generic tasks cannot be deleted using the del_by_fd
4379 task deleting function since generic tasks does not match
4380 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4382 * Added a notion to SILCOPER help file that the SILCOPER works
4383 only on router server, not on normal server.
4385 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4387 * Added for WIN32 support for the new scheduler as well.
4388 Affected file lib/silcutil/win32/silcwin32schedule.c.
4390 * Fixed the SHA1 implementation to work on various platforms.
4392 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4394 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4395 API. It is part of the scheduler now. Everything else is
4396 as previously but some functions has changed their names.
4397 Checkout the lib/silcutil/silcschedule.h for the interface.
4398 Updated all applications to use the new interface. Affected
4399 files are lib/silcutil/silcschedule.[ch].
4401 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4403 * Found a bug in the SKE implementation. The HASH value,
4404 specified by the protocol, was not computed correctly. The
4405 public key of the responder was not added to the computation
4406 even though it is mandatory. Affected file lib/silcske/silcske.c.
4407 This unfortunately causes incompatibilities with older
4408 clients and servers.
4410 * Added WIN32 specific network init and uninit functions:
4411 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4412 the Winsock2. Affected file lib/silcutil/silcnet.h and
4413 lib/silcutil/win32/silcwin32net.c.
4415 * Set the socket always to nonblocking mode on WIN32 after
4416 reading data or writing data. Affected file is
4417 lib/silcutil/win32/silcwin32sockconn.c.
4419 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4421 * Fixed various compilation problems under WIN32. Affected
4422 files lib/silcutil/win32/silcwin32thread.c and
4423 lib/silcutil/win32/silcwin32schedule.c.
4425 * Removed all _internal.h #includes from public header
4426 files. Internal headers must never be included from
4429 Removed also the lib/silcske/payload_internal.h file.
4431 * All include files that may be needed (public and some others
4432 included by the public headers) by application developers are
4433 now copied to the ./includes directory. It does not copy any
4434 internal headers. Affected file Makefile.defines.pre and all
4435 Makefile.am's under lib/ and subdirs.
4437 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4439 * Do not change the ~/.silc directory's permissions automatically.
4440 Affected file irssi/src/silc/core/clientutil.c.
4442 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4444 * Do not cancel the protocol in silc_server_close_connection
4445 it might cause recursion. Now cancelled in the function
4446 silc_server_free_sock_user_data. Affected file silcd/server.c.
4448 * Fixed the silc_server_remove_clients_by_server to regenerate
4449 the channel keys correctly finally. Added also new function
4450 silc_server_remove_clients_channels to actually do it.
4451 Affected file silcd/server.c.
4453 * Fixed the silc_server_new_channel to not crash by giving
4454 wrong router to the new channel. Affected file is
4455 silcd/packet_receive.c.
4457 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4459 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4460 which is given as argument to the silc_client_alloc now.
4461 It can be used to configure the client and set various parameters
4462 that affect the function of the client.
4464 * The USERS command in server did not check whether the channel
4465 is private or secret. Affected file silcd/command.c.
4467 * Added new argument to the USERS command in protocol specification.
4468 The USERS command now can take the channel name as argument
4469 as well. Added support for this in client and server and
4470 updated the protocol specs.
4472 * Completed the GETKEY command in client. It can be now used
4473 to fetch also servers public key not only some clients.
4474 Affected files lib/silcclient/command[_reply].c.
4476 * Added silc_client_get_server to return server entry by the
4477 server name. Affected files lib/silcclient/silcapi.h and
4480 * Redefined the IDENTIFY command in protocol specification to be
4481 more generic. It now can be used to query information about
4482 any entity in the SILC Network, including clients, servers and
4483 channels. The query may be based either the entity's name
4484 or the ID. Added support for this in both client and server.
4486 Affected files silcd/command.c and lib/silcclient/command.c
4487 and command_reply.c.
4489 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4490 the _from_client and _from_server functions. Affected file
4493 * Added silc_client_get_channel_by_id_resolve to the file
4494 lib/silcclient/silcapi.h to resolve channel information by
4495 its ID. Added also silc_client_get_channel_by_id that
4496 does not resolve it from the server.
4498 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4500 * Added SilcServerEntry context into the client library
4501 to represent one server. The INFO command now allocates
4502 these to save the resolved server info. For now on the
4503 client library will also keep information about servers,
4504 connected and resolved with INFO.
4506 The INFO command now allocates the SilcServerEntry context
4507 and saves the server info there. The COMMAND_REPLY in
4508 the INFO now returns the parameters to application in
4509 same order as defined in the protocol specification.
4511 The entries are cached in the client->server_cache.
4513 * The INFO command is now issued after received the Client ID
4514 from the server. Affected file lib/silcclient/client.c.
4516 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4517 to the application as the mode changer might be server.
4518 It is guaranteed that NULL is not returned anymore to the
4519 application. Affected file lib/silcclient/client_notify.c.
4521 The ID Type is now also passed to the application so that
4522 it can check whether the returned entry is SilcClientEntry
4525 Added new function silc_client_get_server_by_id to return
4526 the server entry by ID. Affected files are the
4527 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4529 * Do not create the channel in the Irssi SILC Client when issuing
4530 the JOIN command but when received the sucessful JOIN command
4531 reply. Otherwise the channel might get created even though we
4532 could not join it. The Affected file is
4533 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4535 * Fixed a channel joining bug in router. The router must also
4536 check the channel modes, invite and ban lists etc. when serving
4537 the JOIN command sent by normal server. Affected file is
4538 silcd/command.c. The router now resolves the client's
4539 information from the server who sent the JOIN command if it
4540 does not know it, and processes the JOIN command only after
4543 * Changed the SilcCommandCb to take new argument; void *context2.
4544 Affected file lib/silccore/silccommand.h
4546 The second argument in the command callbacks in the server now
4547 includes the SilcServerCommandReplyContext if the command was
4548 called as pending command callback from the command reply.
4549 Otherwise it is NULL. When called as pending the status of the
4550 command reply will be checked and if it was erronous the
4551 error will be sent to the original sender of the command.
4552 This way the client always receives the error messages even
4553 though the server was actually the one who received the error
4554 when it resent the command to router, for example. Affected
4555 files silcd/command[_reply].[ch].
4557 * Fixed sending WHOWAS command's error message to client if
4558 the requested client could not be found. It was missing.
4561 * Changed the CMODE and CUMODE commands reply arguments in the
4562 protocol specification. The Channel ID is now sent in both
4563 of the commands to identify the channel. Implemented this
4564 new feature to the client and server. Affected files
4565 lib/silcclient/command_reply.c and silcd/command.c.
4567 * Made better checks for invite and ban lists in the JOIN
4568 command in server. Affected file silcd/command.c.
4570 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4572 * The server now performs the incoming host IP/DNS lookup
4573 using the silc_socket_host_lookup and thus does not block
4574 the server anymore. Affected file silcd/server.c.
4576 * Completed the multi-thread support for SILC Scheduler in
4577 the lib/silcutil/silcschedule.c.
4579 * Fixed the configure.in.pre to detect the pthread correctly
4582 * Fixed a deadlock in silc_task_queue_wakeup in the file
4583 lib/silcutil/silctask.c.
4585 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4587 * Added new function silc_schedule_wakeup that is used in
4588 multi-threaded environment to wakeup the main thread's
4589 schduler. It needs to be used when a thread adds a new task
4590 or removes a task from task queues. After waking up, the
4591 scheduler will detect the task queue changes. If threads
4592 support is not compiled in this function has no effect.
4593 Implemented the wakeup mechanism to both Unix and WIN32
4594 systems. Affected files are lib/silcutil/silcschedule.[ch],
4595 lib/silcutil/unix/silcunixschedule.c and the
4596 lib/silcutil/win32/silcwin32schedule.c.
4598 * Added new function silc_task_queue_wakeup to wakeup the
4599 scheduler by the specified task queue. Affected file
4600 lib/silcutil/silctask.[ch].
4602 * The silc_socket_host_lookup_start now wakes up the scheduler
4603 after adding the timeout task. Affected file is
4604 lib/silcutil/silcsockconn.c.
4606 * The silc_socket_host_lookup is synchronous now if the threads
4607 support is not compiled in. However, the callback is still
4608 called asyncronously through the scheduler, anyway. Affected
4609 file lib/silcutil/silcsockconn.c.
4611 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4613 * Added new function silc_socket_host_lookup to perform
4614 asynchronous IP and FQDN lookups for the socket connection.
4615 Affected files lib/silcutil/silcsockconn.[ch].
4617 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4619 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4620 that may or may not compile the mutex support in.
4622 Changed the silc_mutex_alloc interface. It allocates the
4623 mutex now to the sent pointer and returns TRUE or FALSE.
4625 Affected file lib/silcutil/silcmutex.h.
4627 * Wrote the SILC Task Queue interface to support multi-threads.
4628 Affected file lib/silcutil/silctask.[ch].
4630 * Wrote the SILC Scheduler to support multi-threads. Affected
4631 file lib/silcutil/silcschedule.c.
4633 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4635 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4636 in lib/silcutil/win32/.
4638 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4640 * Defined SILC Mutex API and SILC Thread API and implemented
4641 them for Unix. Affected files are
4642 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4643 lib/silcutil/unix/silcunixmutex.c and
4644 lib/silcutil/unix/silcunixthread.c.
4646 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4648 * Fixed the silc_server_remove_clients_by_server's channel
4649 key re-generation. The hash table handling was incorrect
4650 and would not work with many channels. Affected file is
4653 * Fixed some memory leaks around the server code.
4655 * Rewrote the silc_server_get_users_on_channel to support IPv6
4656 based Client ID's. Affected file silcd/server.c.
4658 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4659 specification. However, a separate document must be written
4660 to define the detailed signing procedure and the payload
4661 associated with the flag. Defined the flag to the
4662 lib/silccore/silcchannel.h as well.
4664 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4666 * Changed the dynamic tables to static size tables in the
4667 lib/silccrypt/silchmac.c.
4669 * Removed GCC dependencies from the code. A patch by cras.
4671 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4673 * Do not show the error "Error receiving packet bla bla"
4674 in server if it really was not an error (-2 means that reading
4675 is pending). Affected file silcd/server.c.
4677 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4679 * Fixed a possible crash in silc_server_remove_clients_by_server
4680 in silcd/server.c. Fixed there also some memory leaks.
4682 * Fixed the silc_idlist_replace_client_id. It could replace
4683 wrong key in the hash table. Affected file silcd/idlist.c.
4685 * Do not check whether there are global users on the channel
4686 if the channel->global_users is FALSE. Affected functions
4687 silc_server_remove_from_one_channel and
4688 silc_server_remove_from_channels in silcd/server.c. Also,
4689 do not check if the removed client is local as we can be
4690 sure that global client was not removed from the channel
4691 and checking for global users is not needed.
4693 * The silc_server_remove_clients_by_server now re-generates
4694 the channel keys correctly for those channels that had
4695 clients removed from them. Affected file silcd/server.c.
4697 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4699 * Found the reason of random crashes in the server. We weren't
4700 ignoring the SIGPIPE signal (which can be sent in write())
4701 and it crashed the server. Affected file silcd/silcd.c.
4703 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4705 * Assure that sock->user_data is not NULL in the function
4706 silc_server_packet_send in silcd/packet_send.c.
4708 * Disconnect the remote connection if it could not be added
4709 to any ID lists in the server. The affected file is
4712 * Check in silc_server_packet_send[_real/dest] that the
4713 socket is not disconnecting and ignore the data if it is.
4714 Affected file silcd/packet_send.c.
4716 * Define inline to __inline on native WIN32 compilation.
4717 Affected file includes/silcwin32.h.
4719 * Added some explicit type casts for inline code since MSVC
4720 require them. Affected files lib/silcutil/silcbuffer.h,
4721 lib/trq/silcdlist.h and lib/trq/silclist.h.
4723 * Print warning in log files from now on if the packet
4724 decryption fails. Affected file silcd/server.c.
4726 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4728 * Changed the `say' client operation's interface to accept
4729 new `type' argument to indicate the type of the message sent
4730 by the library. The application may filter the library's
4731 messages according the type. The affected file is the
4732 lib/silcclient/silcapi.h.
4734 * Added two new functions to lib/silcclient/silcapi.h:
4735 silc_client_del_client and silc_client_del_client_by_id.
4736 Affected file lib/silcclient/idlist.c.
4738 * Moved the clientincludes.h from includes/ to silc/ and
4739 serverincludes.h from includes/ to silcd/.
4741 * The modes for the CMODE and CUMODE are now passed as
4742 uint32 for application with COMMAND_REPLY. The affected
4743 file is lib/silcclient/command_reply.c.
4745 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4747 * /WHOIS without arguments shows client's own information.
4748 Affected file lib/silcclient/command.c.
4750 * Changed PING to not accept any arguments. The specs
4751 says that client can ping only the connected server so
4752 requiring an argument is not needed. Affected file is
4753 lib/silcclient/command.c.
4755 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4757 * Fixed a fatal bug in private message sending and reception
4758 encryption and decryption when using private message keys.
4759 The implementation was incorrect and did not follow the
4760 specification. It causd that some of the message were
4761 lost since it did not use the sending and receiving keys
4762 as the protocol suggests. This has been fixed and will cause
4763 incompatibilities with older clients when sending private
4764 message encrypted with private message keys. Affected files
4765 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4766 and various other in Irssi SILC Client.
4768 Added `responder' boolean argument to the functions
4769 silc_client_add_private_message_key[_ske] to indicate when
4770 the key is added as responder or initiator of the key
4773 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4775 * Removed the silc_ske_check_version function and created
4776 a SilcSKECheckVersion callback. Added also a function
4777 silc_ske_set_callbacks that is now used to set all SKE
4778 callbacks. The callback functions are not given to
4779 the SKE functions anymore, but this function is used to
4782 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4784 * Added `silc_version' argument to the silc_client_alloc
4785 to define the version of the application for the library.
4786 The library will use the version string to compare it
4787 against the remote host's (usually a server) version
4788 string. Affected file lib/silcclient/silcapi.h
4790 * Added the KE protocol context to Key Agreement context
4791 in client library so that we can abort the SKE if it
4792 is in process when we get timeout. Affected file is
4793 lib/silcclient/client_keyagr.c.
4795 * Do not resolve the client ID forever if it returns in the
4796 first time that such client does not exist. This was done
4797 for example with private message. Affected file is
4798 lib/silcclient/client_prvmsg.c.
4800 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4802 * Do not add regex.h for WIN32. The affected file
4803 includes/silcincludes.h.
4805 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4806 not work yet 100%. It generates the DLL's automatically
4807 when compiling with --with-win32 under cygwin.
4809 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4811 * lib/contrib/regex.c is not compiled on WIN32.
4813 * Added silc_net_get_socket_opt function to the
4814 lib/silcutil/silcnet.h.
4816 * Added includes/silcwin32.h for WIN32 specific includes
4819 * Do not use ptime structure or any of the posix process
4820 functions on WIN32 in lib/silccrypt/silrng.c.
4822 * Added silc_gettimeofday to provide generic function
4823 for struct timeval on all platforms. Added the function
4824 to lib/silcutil/silcutil.h.
4826 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4828 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4829 library as they clearly belong there. As a plus side we
4830 can make the actual socket connection routines platform
4833 Added also new generic function silc_socket_read and
4834 silc_socket_write (that used to be silc_packet_[read/write].
4835 The implementation of these are platform specific.
4837 * Added WIN32 specific routines of silc_socket_[read/write]
4838 to lib/silcutil/win32/silcwin32sockconn.c.
4840 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4842 * Added preliminary support for native WIN32 compilation under
4843 cygwin (using the -mno-cygwin option for GCC) to the
4844 ./configure.in.pre. The --with-win32 now prepares the
4845 compilation for native WIN32.
4847 * Rewrote the SILC Scheduler interface in the file
4848 lib/silcutil/silcschedule.h. The scheduler is now context
4849 based and does not have anymore any global static scheduler.
4850 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4851 and created lib/silcutil/win32 directory for WIN32 based
4854 * Added Unix specific network routines to the
4855 lib/silcutil/unix/silcunixnet.c and the old
4856 lib/silcutil/silcnet.c includes now only generic routines.
4858 Added WIN32 specific network routines to the
4859 lib/silcutil/win32/silcwin32net.c.
4861 * Added Unix specific utility functions from the
4862 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4864 * Added WIN32 SILC Scheduler to the file
4865 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4868 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4870 * Do not handle JOIN notify in the server if the target client
4871 is not registered (idata->registered == FALSE). The affected
4872 file is silcd/packet_receive.c.
4874 * Update the nickrec->founder in event_cumode in the Irssi SILC
4875 client. Affected file irssi/src/silc/core/silc-channels.c.
4877 * Fixed the CUMODE_CHANGE notify handling in the server when
4878 server and router are announcing their clients on channels.
4879 Now the mode changes are saved and notified correctly. The
4880 affected file is /silcd/packet_receive.c.
4882 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4883 They really did not replace the cache entry in the ID Cache.
4884 Now they do that. Affected file silcd/idlist.c.
4886 * Fixed the KICK notify handling in the Irssi SILC client to
4887 update the channel records so that the kicked client does not
4888 appear to be on the channel. The affected file is
4889 irssi/src/silc/core/silc-channels.c.
4891 * Always update the conn->current_channel when executing command
4892 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4894 * Fixed the KILL notify handling in Irssi SILC client to remove
4895 the killed client on all channels.
4897 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Fixed the silc_parse_command_line to remove extra spaces
4900 from the start and end of the arguments. Affected file is
4901 lib/silcutil/silcutil.c.
4903 * Cancel and free any active protocol in the function
4904 silc_server_close_connection. Affected file silcd/server.c.
4906 * Cancel and free any active protocol in the function
4907 silc_client_close_connction. Affected file is
4908 lib/silcclient/client.c.
4910 * Do not execute the KILL command for clients that are in
4911 history (ie. they are not in the network). Affected file is
4914 * Fixed KILL notify handling, client does not crash anymore.
4915 Affected file irssi/src/silc/core/silc-channels.c.
4917 * Reduced the default packet buffer size from 2048 to 1024 in
4918 lib/silccore/silcpacket.c.
4920 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4921 counter to the SKE context that is incresed when the SKE library
4922 performs async operation outside the library. If the outside
4923 process frees the SKE context and FREED status will be set
4924 and the library will detect after the sync operation that the
4925 libary is freed. The affected files are
4926 lib/silcske/silcske[_status].[ch].
4928 * Resolve the client entry information in the function
4929 silc_client_channel_message to assure that NULL pointer is not
4930 passed as client entry to the application. */
4932 * Fixed the task timeout calculation to assure that there is
4933 never negative timeouts. The affected file is
4934 lib/silcutil/silcschedule.c.
4936 * Fixed the channel user mode notification sending in server.
4937 It was sent point-to-point to the router (or to server by router)
4938 but it needs to be destined to a channel. The routines now
4939 supports sending the channel user mode notifys to the channels
4940 when announcing clients and channels. Affected files are
4941 silcd/server.c and silcd/packet_receive.c.
4943 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4944 It did not actually replace the old channel entry in the cache.
4945 Affected file lib/silcclient/client_notify.c.
4947 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed a possible crash in silc_packet_send_prepare. It now
4950 assures always that there is enough space in the buffer and
4951 at the tail area of the buffer (for MAC).
4953 Fixed the inbound buffer reallocation in silc_packet_read.
4954 It was old code and did not handle the reallocation correctly.
4957 The affected file is lib/silccore/silcpacket.c.
4959 * Fixed buffer overflow in silc_parse_nickname in the file
4960 lib/silcutil/silcutil.c.
4962 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * make install generates new server keys only if there is not
4967 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4970 Added check that if the NOREPLY is set then we will not send
4971 the away message. This avoids infinite loop of away messages
4972 if both clients are away. The affected file is
4973 lib/silcclient/client_prvmsg.c.
4975 * Fixed client crash if /NICK was given without arguments.
4976 Affected file lib/silcclient/command.c.
4978 * Server does not send the invite list in INVITE command back
4979 to the client if the list was not altered. Added this notion
4980 to the protocol spec as well. Affected file silcd/command.c.
4982 Fixed possible crash in INVITE command by checking the
4983 value of silc_server_get_client_route command.
4985 * Fixed the INVITE notify type handling. The arguments are now
4986 taken in correct order and client does not crash. The affected
4987 file is irssi/src/silc/core/silc-channels.c.
4989 Removed the "Inviting xxx to channel" message from the
4990 client library away and let the application handle it.
4991 Affected file lib/silcclient/command.c. Added that message
4992 to Irssi SILC client's message formats.
4994 * Fixed CMODE command crash in client. It now checks the
4995 amount of arguments correctly and does not crash. The affected
4996 file is lib/silcclient/command.c.
4998 * Do not create new channel automatically in silc_channels_join
4999 but check whether the channel by that name already exists.
5000 Affected file irssi/silc/core/silc-channels.c.
5002 * Do not send the SERVER_SIGNOFF to router if the disconnected
5003 entity was the router. Affected file silcd/server.c.
5005 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5006 SILC client as it was missing from there.
5008 Added the handling of the KICK notify to the Irssi SILC client
5009 as it was missing. Added "you have been kicked" message to
5010 Irssi SILC client's message modules formats.
5012 Added the handing of the KILL notify to the Irssi SILC client
5013 as it was missing. Added the kill message module formats
5016 The affected file is irssi/src/silc/core/silc-channels.c.
5018 * The router did not save the channel mode the server announced.
5019 Affected file silcd/packet_receive.c.
5021 * Fixed a possible crash in INFO command in server. If the
5022 server did not provide the server info it crashed. Affected
5023 file silcd/command.c.
5025 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Fixed the GETKEY command in the server to check also the
5028 global list. Otherwise the GETKEY would not work correctly
5029 in normal SILC server. Affected file silcd/command.c.
5031 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Fixed GETKEY crash, it crashed if the command did not succseed.
5035 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5038 is now real and not just an macro interface to GMP.
5040 Removed the entire GMP from the source tree and imported new
5041 NSS MPI library instead. Reason for removing GMP is that it is
5042 extremely large and compiles extremely slow. The NSS MPI
5043 is only a few files and compiles in less than 10 seconds.
5044 The speed is also about the same as GMP. The MPI is imported
5045 to lib/silcmath/mpi.
5047 If the system has GMP installed we will still use the GMP.
5048 If it is not then the NSS MPI will be compiled.
5050 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Merged a long nickname (127 characters long) crash bugfix from
5053 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5055 * Merged a freed memory reference bugfix from Irssi CVS tree.
5056 Affected file irssi/src/core/commands.c.
5058 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Added the server's public key sving and verification to the
5061 server when performing the SKE. This was missing and the
5062 remote server's (or router's) public key was accepted without
5063 checking whether we have it previously or trust it at all.
5064 Affected file silcd/protocol.c.
5066 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Check in the silc_server_timeout_remote if protocol is active
5069 and make sure that the protocol's final callback is called so
5070 that all memory if freed. Affected file silcd/server.c.
5072 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * silc_server_whois_send_reply crashed the server if the nickname
5075 was 127 characters long. Affected file silcd/command.c.
5077 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Added sanity check to the silc_server_new_client. If the hostname
5080 is provided inside username then check that the provided hostname
5081 really is the same as the resolved one. If the hostname was not
5082 resolved then check it from the public key. Affected file is
5083 silcd/packet_receive.c.
5085 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5086 if the server disconnected us and the connection is not valid
5087 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5089 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5090 the library to the lib/silcutil/silcutil.[ch].
5092 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Close log file after open. Affected file
5095 lib/silcutil/silclog.c.
5097 * Check whether sock == NULL in silc_client_send_packet and return
5098 if it is. Affected file lib/silcclient/silcclient.c.
5100 * Check rec->entry == NULL in the Irssi SILC Client before
5101 sending the channel message. Affecte file is
5102 irssi/src/silc/core/silc-servers.c.
5104 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Merged a splitted window bugfix from Irssi CVS tree. The
5107 affected file is irssi/src/fe-text/textbuffer-view.c.
5109 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5110 It did not print nickname.
5112 * Improved the distributions system a bit.
5114 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5117 irssi/src/fe-text/gui-window.c.
5119 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5120 to in-active server. The affected file is
5121 irssi/src/silc/core/client_ops.c.
5123 * Resolve the client in USERS command reply if the entry does
5124 not have username resolved. The affected file is
5125 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5126 command to WHOIS command to really resolve stuff. The USERS
5127 is not used any more in any critical section so WHOIS can
5128 be used even though it might be slower than IDENTIFY.
5130 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5133 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Changed the protocol API a bit more consistent in the
5136 lib/silccore/silcprotocol.[ch].
5138 * Changed the following headers to ROBODoc format:
5140 lib/silccore/silcpayload.h
5141 lib/silccore/silcprotocol.h
5142 lib/silccore/silcsockconn.h
5144 All core library headers are now formatted.
5146 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Fixed a bug in Irssi SILC client; do not show that you are
5149 server/router operator if you really are not. Affected file is
5150 irssi/src/silc/core/client_ops.c.
5152 * Renamed silc_command_free_payload to silc_command_payload_free.
5153 Affected file lib/silccore/silccommand.h
5155 * Added silcmath.h to include the prototoypes of various routines
5156 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5159 * Changed the following headers to ROBODoc format:
5161 lib/silccore/silcchannel.h
5162 lib/silccore/silccommand.h
5163 lib/silccore/silcid.h
5164 lib/silccore/silcidcache.h
5165 lib/silccore/silcmode.h
5166 lib/silccore/silcnotify.h
5167 lib/silccore/silcpacket.h
5168 lib/silcmath/silcmath.h
5170 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Added checking to the server code not to start the server if
5173 ciphers and stuff are not configured properly. Affected files
5174 silcd/serverconfig.[h] and silcd/server.c.
5176 * Changed the layout of the header files of the public interfaces
5177 in the SILC libraries. The new layout supports ROBODoc
5178 documentation tool (and some others) so that it is easy to create
5179 a library reference manual. All the other headers and source
5180 code must still follow the CodingStyle document. Also source
5181 code must not include these ROBODoc stuffs, only the headers.
5182 Furthermore, all public interface headers must now be named
5183 by using `silc' prefix, example: silcapi.h, silccipher.h.
5184 Some files were renamed due to this. All the other headers
5185 must not be used as public interfaces. I will update the
5186 CodingStyle document later. Changed following headers, so far:
5188 lib/silcclient/silcapi.h
5189 lib/silccore/silcauth.h
5190 lib/silccore/silcprivate.h
5191 lib/silccrypt/silcdh.h
5193 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Removed silc_client_packet_send_flush from the client library
5198 as it is not needed. Affected file lib/silcclient/client.[ch].
5200 * Added printing of message of unresolved authentication method
5201 to the Irssi SILC client. Added it to the module formats.
5202 Removed the same message from the client library.
5204 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Added new distribution feature, DISTLABEL. Every distribution
5207 can define own preprocessor label that can be used in the
5208 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5209 file distributions, acconfig.h.pre and prepare.
5211 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added Makefile.defines_int to include the actual definitions
5214 for Makefile.defines.in. Tested the new distribution system,
5215 created distributions and tested installation.
5217 * Added AWAY message printing to the Irssi SILC client. Added
5218 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5220 * Added SCONNECT command to call the SILC's CONNECT command.
5221 Cannot use CONNECT directly since Irssi uses that internally.
5222 Affected file irssi/src/silc/core/silc-servers.c.
5224 Added ACTION local command. It is same as ME command but takes
5225 the channel as mandatory argument.
5227 Rewrote some of the Irssi's help files to suite for SILC
5230 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Added Makefile.defines[.in] that should for now on be included
5233 in all Makefile.am file in the source tree. That file includes
5234 all common compilation definitions for SILC source tree.
5236 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Minor changes to the ./prepare script to change the package
5239 name according the distribution name to the configure.in.
5241 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Created new distribution system. Added file `distributions'
5244 that defines all the distributions that can be created out of
5245 the SILC source tree. The ./prepare script now reads that
5246 file to determine how to prepare the distributions. The
5247 first argument to the ./prepare is the name of the distribution
5248 and second is the version of the distribution. If given
5249 without arguments it creates the default (toolkit) distribution
5250 with the default version (defined in ./prepare).
5252 All Makefile.am files that are subject to the distributions
5253 are now named as Makefile.am.pre. These are ./Makefile.am
5254 and lib/Makefile.am. Others may be changed later.
5256 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added invite list, ban list, some key management and connection
5259 error message printing to module formats in the Irssi SILC client.
5261 * Added new silc_client_set_away_message to set the away message
5262 that is back to the person who sent private message. The
5263 affected file lib/silcclient/silcapi.h and the
5264 lib/silcclient/client_prvmsg.c.
5266 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Fixed the private message sending in the Irssi SILC client,
5269 added local command KEY to the Irssi SILC client.
5271 Added key management and key agreement message formats to the
5272 irssi/src/fe-common/silc/module-formats.[ch].
5274 Added USERS (alias WHO) printing, server/router operator
5275 indication and LIST command printing to the module formats.
5277 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Fixed channel joining notify handling, cumode notify handling
5280 from Irssi SILC client.
5282 * Added SILC specific module-formats to the Irssi SILC client so
5283 that SILC specific message hilighting, colors etc is possible.
5284 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5286 Added channel mode, channel user mode, actions, notices,
5287 whois and whowas printing to the the module-formats.c.
5289 * Fixed a bug in channel deletion in the server. The channel
5290 is not left to the cache even if the channel founder auth mode
5291 is set when there are no users anymore on the channel. Affected
5292 file silcd/server.c.
5294 * The silc_net_localhost now resolves the entire hostname including
5295 the domain name. Affected file lib/silcutil/silcnet.c.
5297 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Changed the ask_passphrase client operation to be ascynchronous.
5300 It has now a completion callback and a context that the
5301 application must call after it has got the passphrase from
5302 the user. Affected files lib/silcclient/silcapi.h,
5303 lib/silcclient/protocol.c, lib/silcclient/command.c and
5306 Added SilcAskPassphrase callback that the application calls
5307 to deliver the passphrase to the library.
5309 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5310 The public key verification and especially a certificate
5311 verification is asynchronous procedure.
5313 Added new SILC_SKE_STATUS_PENDING status to indicate the
5314 request is pending and a callback will be called to finalize
5317 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5318 indicate that remote end did not send its public key (or
5319 certificate), even though we require it. Added check for this
5320 condition in the SKE. This was a security bug, now fixed.
5322 Defined new SilcSKEVerifyCbCompletion callback that is called
5323 when the verification process is completed.
5325 The affected files lib/silcske/silcske_status.h and
5326 lib/silcske/silcske.[ch].
5328 * Changed the verify_public_key client operation to be async
5329 as well. Defined SilcVerifyPublicKey callback that is used to
5330 indicate the success of the public key verification process.
5332 Changed the server and client to use the new async client
5335 * Changed the Irssi SILC client's internal scheduler to be called
5336 twice as many times as it used to be. As a result the client
5337 should be a bit faster now. Affected file is
5338 irssi/src/silc/core/silc-core.c.
5340 * Added support to Irssi SILC client of asynchronous public key
5341 verification and passphrase inquiry. Affected file is
5342 irssi/src/silc/core/silc-core.c.
5344 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Do not say "You have left channel %s" in client library.
5347 Moved it to the application. Affected files are
5348 lib/silcclient/command.c and silc/client_ops.c.
5350 * Fixed silc_client_get_clients. Command context was not
5351 duplicated and was freed memory in the callback. Affected
5352 file lib/silcclient/idlist.c.
5354 * Do not say "you are now talking..." on JOIN command in the
5355 client library. The appliation must handle it.
5357 * Do not say ".. changed topic to" in command reply in the
5358 client libary. The application must handle it.
5360 * Fixed TOPIC command sending in the client library.
5362 * Fixed a memory leak in silc_client_command_free in the file
5363 lib/silcclient/command.c.
5365 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * Imported a modified version of Irssi client to the source tree.
5368 The Irssi will be used to create a new client called
5369 Irssi SILC. Imported to irssi/.
5371 Added silc_core_init_finish function to the Irssi. Affected
5372 file irssi/configure.in.
5374 A lot changes in the Makefile.ams around the irssi tree.
5376 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Do not rehash if the new size is same as the old size of the
5379 hash table, in the silc_hash_table_rehash*. The affected file
5380 lib/silcutil/silchashtable.c.
5382 * Replaced hash_table_del_by_context calls from the server
5383 (when channel->user_list and client->channels) to the
5384 hash_table_del as it is sufficient and faster.
5386 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Added silc_hash_table_list, silc_hash_table_get and the
5389 SilcHashTableList structure to provide an alternative way to
5390 traverse the hash table. The affected files are
5391 lib/silcutil/silchashtable.[ch].
5393 * Changed the server's idlist routines to use the hash table
5394 routines to optimize the code.
5396 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Replaced the client entry's `channel' list and channel entry's
5399 `user_list' list to hash tables for optimized lookup. Changed
5400 the code to use the hash table interface around the code.
5401 Affected file lib/silcd/idlist.[ch].
5403 * Added `auto_rehash' boolean argument to the function
5404 silc_hash_table_alloc to indicate whether the hash table should
5405 auto-rehash when it thinks is appropriate time. It will
5406 increase the hash table size if the there is twice as much
5407 entries in the table than the size of the table, and will
5408 decrease the size if there are twice as less entries than
5409 the size of the table.
5411 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5415 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * silc_idcache_purge_by_context deletes the entry now by context
5418 as it is supposed to do. Affected file lib/silccore/idcache.c.
5420 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5421 client is not anymore valid (WHOWAS givens the info) and not
5422 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5424 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Removed the `data' and `data_len' arguments from the ID Cache
5427 interfaces and added `name' argument. ID Cache does not handle
5428 anymore the binary data only a names associated with given ID.
5430 * When hashing a Client ID with silc_hash_id the entire ID is
5431 not hashed anymore, instead only the hash of the Client ID is
5432 hashed. This way we can access the Client ID from the cache
5433 with Client ID but with the hash of the ID (which is a hash of
5434 the nickname) as well without any difference in performance.
5436 Added also silc_idcache_find_by_id_one_ext to do one on one
5437 searching when we have the actual ID. Added also function
5438 silc_hash_client_id_compare. The affected files are
5439 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5441 * When hashing the name associated with a ID it is always done
5442 in lowercase. This way we can access the cache without worrying
5443 about case-sensitivity, even though, for example nicknames are
5446 * Fixed a bug in server with channel message sending. It put
5447 wrong ID type as destination ID. The affected file
5448 silcd/packet_send.c.
5450 * silc_idcache_del_by_context now deletes from all hash tables
5451 by context. Affected file lib/silccore/idcache.c.
5453 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Changed the client library to use the new ID Cache interface.
5456 Changes around the source tree.
5458 * Added silc_hash_table_rehash_ext to rehash with specific
5459 hash function. Affected file lib/silcutil/silchashtable.[ch].
5461 * Added silc_hash_string_compare to compare two strings in the
5462 hash table. Affected file lib/silcutil/silcutil.[ch].
5464 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Added new function silc_idcache_del_by_context into the
5467 lib/silccore/idcache.[ch].
5469 * Changed the server's ID list routines to use the new ID Cache
5470 interface. Changes around the source tree.
5472 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Added silc_hash_table_del[_by_context]_ext functions in to the
5475 lib/silcutil/silchashtable.[ch].
5477 Removed silc_hash_table_find_all* routines and added new
5478 silc_hash_table_find_foreach to replace them.
5480 Added silc_hash_table_replace_ext function as extended
5481 replacing function. Separated the simple hash table interface
5482 from the extended hash table interface in the file
5483 lib/silcutil/silchashtable.h.
5485 * Fixed minor bugs and changed it to use some of the new
5486 hash table functions in lib/silccore/idcache.c
5488 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Added new function silc_hash_table_find_all to return all keys
5491 in the hash table by the specified key. As the hash table is
5492 collision resistant it also makes it possible to have several
5493 duplicate keys in the hash table. This function may be used to
5494 find all of the keys from the hash.
5496 Added user_context arguments to the SilcHashFunction,
5497 SilcHashCompare and SilcHashDestructor to deliver user specified
5500 Added new fuctions silc_hash_table_find[_all]_ext to do
5501 extended lookup with specified hash and compare functions and
5502 specified user contexts.
5504 Added new function silc_hash_table_add_ext to add the key
5505 with specified hash function and user context.
5507 Added new function silc_hash_table_foreach to traverse all
5508 entrys in the hash table. Added SilcHashForeach callback
5511 Added new function silc_hash_table_del_by_context to delete
5512 the entry only if the context associated with the key matches.
5514 Affected files are lib/silcutil/silchashtable.[ch].
5516 * Removed silc_hash_[server/client/channel]_id and added just
5517 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5518 silc_hash_id_compare to compare two ID's using as the hash table
5519 comparison function. Added also silc_hash_data to hash
5520 binary data and silc_hash_data_compare to compare it.
5522 * Removed silc_idlist_find_client_by_hash as it is not needed
5523 anymore. Affected file silcd/idlist.[ch].
5525 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5526 to use internally the SilcHashTable. The new ID Cache is a lot
5527 faster than the old one. Some of the ID Cache interface was also
5528 rewritten and obsolete and stupid functions were removed.
5530 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Added entry_count field to the SilcHashTable to keep the number
5533 of the entries in the table. Implemented the function
5534 silc_hash_table_rehash. Added new function
5535 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5537 Fixed a minor bug in silc_hash_table_free.
5539 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5540 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5541 into the lib/silcutil/silcutil.[ch].
5543 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Implemented a collision resistant hash table into the
5546 lib/silcutil/silchashtable[ch]. See the header and the source
5547 for the SilcHashTable API.
5549 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Merged dotconf version 1.0.2 into lib/dotconf.
5553 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Do not compile anything in lib/silcsim/* if the SIM support
5556 is not enabled. The tree should now compile without problems
5559 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Compiled the SILC under cygwin. Compiled and tested briefly
5562 without problems. More tests needed. The SIMs didn't compile
5565 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5567 * Fixed possible crash in silc_get_username in the
5568 lib/silcutil/silcutil.c.
5570 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Fixed a va_arg in silc/client_ops.c.
5574 * Oops, RC5 routines were named AES and caused some problems
5575 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5577 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Added new SilcIDIP structure into the lib/silccore/id.h and
5580 replaced the old `ip' fields from all SILC ID's to that type.
5581 This is a step towards IPv6 support.
5583 The silc_id_get_len takes now the ID as an extra argument.
5584 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5585 both IPv4 and IPv6 based ID's.
5587 The affected files are lib/silccore/id.[ch] and other files
5588 around the tree using these routines.
5590 * Removed the ID length arguments in server from various
5591 silc_server_send_notify_* routines -> they are not needed
5594 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Fixed memory leak in silc_encode_pem_file in the file
5597 lib/silcutil/silcutil.c.
5599 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Check minor version as well in the SKE. Affected files are
5602 silcd/protocol.c and lib/silcclient/protocol.c.
5604 * Added --identifier option to the server so that an identifier
5605 can be when creating the public key for the server. Affected
5606 file is silcd/silcd.c.
5608 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5609 lib/silccrypt/silcpkcs.c.
5611 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Register default ciphers and stuff when using -C option with
5614 the server. Affected file sildc/silcd.c.
5616 * Put back the servers public key filename format, it is better
5617 than the new one. For now, the client keys are saved with the
5618 new filename format. The affected file silc/client_ops.c.
5620 * Implemented the Cipher API for the rest of the ciphers that
5621 did not implement it or implemented it the wrong way.
5623 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Register default ciphers and stuff when using the -S option
5626 in the client. Affected file silc/silc.c. Same also when
5627 creating new key pair with -C option.
5629 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Fixed the silc_verify_public_key client operation function to
5632 save the public keys differently. The fingerprint is now
5633 used as filename and not the hostname. This way also the
5634 client keys are saved uniquely and not with hostnames. The
5635 affected file is silc/client_ops.c.
5637 * Trimmed the silc_hash_fingerprint function to remove extra
5638 whitespaces from the end of the fingerprint. The affected
5639 file is lib/silccrypt/silchash.c.
5643 * Added silc_cipher_register_default function to register all
5644 default ciphers. It can be used when configuration files
5645 does not exist and the application does not want any specific
5646 ciphers in any specific order.
5648 The SilcDList is now used as silc_cipher_list dynamically
5649 allocated cipher list. Removed the static list all together
5650 and now all ciphers must be allocated to the dynamic list.
5651 The silc_cipher_alloc routine was changed to check only the
5654 All silc_cipher_* routines that used to return int returns
5657 The affected files lib/silccrypt/silccrypt.[ch].
5659 * The same thing was done to silc_hash_* as for silc_cipher_*
5660 routines. Affected files lib/silccrypt/silchash.[ch].
5662 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5663 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5664 Added also silc_pkcs_[un]register[_default] functions.
5665 Removed the data_context from the PKCS API.
5667 * Added silc_hmac_register_default function to register default
5668 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5669 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5670 to unregister all hmacs at once.
5672 * Register the default ciphers, hash functions, PKCSs and HMACs
5673 if client's configuration file does not exist. The affected
5676 * The client did not load the hash functions from the SIM
5677 modules at all. Added support for this. Affected file is
5678 silc/clientconfig.c.
5680 * When decoding public key with silc_pkcs_public_key_decode, check
5681 the supported algorithm only if PKCS are registered. Affected
5682 file lib/silccrypt/silcpkcs.c. The same was done with the
5683 silc_pkcs_private_key_decode.
5685 * Fixed the SILC List routines to keep the list always in order.
5686 It used to change the list's order when traversing the list but
5687 not it preserves the order. Affected file lib/trq/silclist.h.
5689 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Added the client library to use the SilcSocketConnection's
5692 reference counter (by silc_socket_dup) to prevent the bug that
5693 the socket object may be freed underneath async operation.
5695 * The name resolv library checking fixes in the configure.in.pre.
5698 * Created new version of the protocol drafts for future
5699 development. The -03 drafts are the ones that will be changed
5700 in the trunk now and the -02 will remain as they are.
5702 * Send list of CUMODE notifys to the router when announcing
5703 the channel users to the router. Affected file silcd/server.c.
5704 If the router receiving channel founder CUMODE for a channel
5705 that already has channel founder it will send CUMODE notify
5706 to the sender to remove the channel founder rights from the
5707 announced client. Affected file silcd/packet_receive.c.
5709 * The CUMODE notify may now use Server ID as well as the entity
5710 who changes the mode. Updated protocool specs.
5712 * Updated INSTALL and README files.
5714 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * New web pages in the http://silc.pspt.fi. The pages was
5721 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Implemented the [DenyConnectin] config section in the server.
5724 Added silc_server_config_denied_conn to check whether incoming
5725 connection is denied. Affected file silcd/serverconfig.[ch].
5727 * Do not check the ports when checking the incoming configuration
5728 data if the port is 0, meaning any. Affected file is
5729 silcd/serverconfig.c.
5731 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Fixed buffer overflow in silc_string_compare in the file
5734 lib/silcutil/silcutil.c.
5736 * Fixed double free in silc_server_command_leave in the file
5739 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Fixed the version checking in the server. Affected file is
5744 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * Fixed the configuration data fetching when accepting new
5747 connections in the server. Affected file silcd/server.c.
5749 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added `sender_entry' argument to the function
5752 silc_server_packet_relay_to_channel so that we can check
5753 whether some destination actually belongs to the same route
5754 the sender belongs (ie, we must not resend the packet to the
5755 sender). Affected file silcd/packet_send.[ch].
5757 * Added `servername' field to the SilcClientEntry in the server
5758 to hold the name of the server where client is from. Affected
5759 file is silcd/idlist.h.
5761 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Moved the channel message encrypting in the router betwen
5764 router connections from silc_server_channel_message to the
5765 silc_server_packet_relay_to_channel since we want to check
5766 whether we have anybody channel before encrypting anything.
5767 Affected files silcd/packet_[receive/send].c.
5769 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Fixed the [AdminConnection] server config section to support
5772 multiple entries. Affected file silcd/serverconfig.c.
5774 * Added support into the server to check the validity of the
5775 incoming connection before executing any KE or authentication
5778 * The connection configuration is now saved to the KE and
5779 connection auth protocol contexts and not fetched anymore in
5780 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5782 * The local hosts listenning address and port is also resolved
5783 now when starting the server. We want to have the socket object
5784 to include the real address and port for the listener. Added
5785 new function silc_net_check_local_by_sock into the files
5786 lib/silcutil/silcnet.[ch].
5788 * Fixed a broadcast bug in server -> do not broadcast if we
5791 * Fixed a routing bug. Do not route broadcast packets ever.
5792 Broadcast packets must be processed always and not routed since
5793 they may be destined to some other host than yourself and thus
5794 would get routed without no good reason. Affected file is
5797 * Added function silc_server_config_is_primary_route to check
5798 whether primary router connection has been configured (a router
5799 configuration that we are initiating). If there is not, we
5800 will assume that there is only two routers in the SILC network
5801 and we will use the incoming router connection as our primary
5802 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5804 * Changed the order of the broadcasting. Broadcast _after_ the
5805 packet has been processed not before. Affected file is
5808 * Fixed a [ClientConnection] parsing bug. The port was never
5809 parsed correctly thus resulting to port 0. Affected file
5810 silcd/serverconfig.c.
5812 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5813 argument and did not set the broadcast packet flag. Affected
5814 file silcd/packet_send.c. Fixed same bug in the function
5815 silc_server_send_notify as well.
5817 * If we receive NEW_ID packet for our own ID in the server, ignore
5820 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Removed the nickname from the Private Message Payload.
5825 Updated the code and the protocol specs.
5827 * Updated protocol specs for submitting to the IETF.
5829 * Tweaked the Random Number Generator a bit. Affected file
5830 lib/silccrypt/silcrng.c. Exported a new function
5831 silc_rng_[global]_add_noise which can be used to add more
5834 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Do not parse packets with different timeout when protocol
5837 is active -> may cause problem with rekey. Affected file
5840 * When server receives signoff notify it must not create
5841 new channel key if the client is on any channels since the
5842 sender of the signoff notify will create it.
5844 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Added printing of error messages during SKE protocol from the
5847 failure packet sent by server during SKE. Affected file
5850 * Removed the client's failure_callback handling with timeout
5851 and handle it immediately when received.
5853 * The SKE library returned wrong type in SUCCESS and FAILURE
5854 packets. They must be 32 bit MSB not 16 bit MSB.
5856 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Ok, rewrote the logic of the re-key and now it seems to work.
5859 I tested it on high traffic with frequent re-keys without
5860 problems. Added hmac_receive (and renamed hmac to hmac_send)
5861 in SilcClientConnection in lib/silcclient/client.h and
5862 in SilcIDListData in silcd/idlist.h. Also, removed the
5863 SilcPacketParserContext's cipher and hmac fields as they are
5864 not needed anymore and actually caused some problems when
5865 the ciphers and hmac's changed underneath the packet parser.
5867 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5869 * If re-key protocol is active then process the incoming packets
5870 synchronously since we must assure that icoming packets encrypted
5871 with the old key is processed before the new keys is set to
5872 use. This is true other packets than for REKEY packets.
5873 Affected file silcd/server.c. The same was done to client library
5874 as well, affected file lib/silcclient/client.c.
5876 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Fixed bug in client and server to accept the force send if
5879 the packet is send from silc_[server/client]_packet_process
5880 function. Otherwise the packets are never delivered, oops.
5882 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Disable force sending of packets when REKEY protocol is active.
5885 We must assure that no packet is sent directly when rekey is
5886 performed. All packets must be sent through packet queue.
5887 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5888 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5889 function is silc_[server/client]_packet_send_real to check
5892 * Replaced the SIM paths from example config files to
5893 /usr/local/modules. Also, make install creates now
5894 /usr/local/silc/logs directory to hold all the SILC server
5897 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Made the configure.in.pre work on Solaris. Patch by salo.
5901 * Made all ciphers compatible with non-x86 machines. Defined
5902 CBC mode macros into lib/silccrypt/ciphers_def.h.
5904 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Fixed the make install.
5908 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * When MAC computation fails the silc_packet_decrypt returned 0
5911 even though it was supposed to return -1. Fixed this. The
5912 affected file is lib/silccore/silcpacket.c.
5914 * Do not replace the config files in /etc/silc (in make install)
5915 if they already exist. Affected file ./Makefile.am.
5917 * Do not send re-key packets immediately but through packet queue.
5918 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5920 * Changed silc_net_check_host_by_sock to return FALSE if the
5921 IP/DNS could not be resolved. Though, it returns the IP address
5922 now even if it could not resolve it (but returns also FALSE).
5923 Affected file lib/silcutil/silcnet.[ch].
5925 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Added silc_pkcs_decode_identifier to decode the public key's
5928 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5929 Added also silc_pkcs_free_identifier. Added also new context
5930 SilcPublicKeyIdentifier.
5932 * Added -S option to the silc client. It is used to dump the
5933 contents of the specified public key file.
5935 * Changed the PKCS api to return the public key length when
5936 setting the public key.
5938 * Fixed a fatal bug in the public and private key file loading.
5939 Affected file lib/silccrypt/silcpkcs.c.
5941 * Execute the packet parsing for client with zero (0) timeout
5942 if the protocol is active. Affected file silcd/server.c.
5944 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Made the key generation options to the silcd program. Added
5947 -C option, equivalent to client's option.
5949 * Added new [ServerKeys] config section to the server. It
5950 configures the server's public and private key.
5952 * Defined generic Public Key Payload into the protocol
5953 specification to send specific type of public keys and
5956 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5957 public key or certificate.
5959 * Implemented the GETKEY command to the server and to the
5960 client library and on user interface.
5962 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Made preliminary `make install' work.
5966 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Added SilcServerRekey context into silcd/idlist.h.
5970 * Added the PFS support as defined in the specification to the
5971 SKE protocol. Affected files lib/silcske/*.c.
5973 * Added `ske_group' field to the SilcServerRekey context to hold
5974 the number of the SKE group that is used with PFS in re-key.
5975 Affected file silcd/idlist.h.
5977 * Added PFS re-key support to the server. Affected file is
5980 * Added silc_protocol_cancel to cancel execution of the next
5981 state of the protocol. Affected file is
5982 lib/silccore/silcprotocol.[ch].
5984 * Added the re-key support with and without PFS to the client
5985 library. Re-key is performed once in an hour, by default.
5987 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5988 Added silc_client_rekey_callback and silc_client_rekey_final.
5989 Affected files are lib/silcclient/protocol.[ch] and
5990 lib/silcclient/client.[ch].
5992 * Removed the `hmac_key' and `hmac_key_len' fields from the
5993 SilcClientConnection structure; not needed. Affected file is
5994 lib/silcclient/client.h.
5998 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Do not ask whether user wants to use the negotiated private key
6001 for private messages, just use it. Affected file is
6002 silc/local_command.c.
6004 * Added `send_enc_key' and `enc_key_len' fields to the
6005 SilcIDListData structure since they are needed in the re-key
6006 phase. Affected file is silcd/idlist.[ch].
6008 * Implemented the simple re-key protocol into the server.
6009 Affected files silcd/server.c and silcd/protocol.[ch]. The
6010 re-key will be performed once in an hour, by default.
6012 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6013 Added silc_server_rekey, silc_server_rekey_callback and
6014 silc_server_rekey_final.
6016 * Removed Tunneled flag from the protocol. Updated the code
6017 and the specifications.
6019 * Adde `pfs' field to the SilcIDListData to indicate whether
6020 the PFS is to be performed in the re-key. Affected file is
6023 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6026 int64 of at least the xintXX size. If void * is less that 4
6027 bytes uint32 * will be used. Defined bool as boolean.
6029 * Changed _ALL_ unsigned long and unsigned int to uint32,
6030 unsgined short to uint16 in the source tree.
6032 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6033 not handle clients that has entry->data.registered == FALSE.
6034 They are not in the network anymore. Affected file is
6037 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Implemented the sending of the SERVER_SIGNOFF notify in the
6040 server. Affected file is silcd/server.c.
6042 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6043 Added also silc_notify_payload_encode_args into the
6044 lib/silccore/silcnotify.[ch].
6046 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6047 Affected file silcd/packet_receive.c.
6049 * Implemented the SERVER_SIGNOFF notify handling in the client
6050 library. Affected file lib/silcclient/client_notify.c. Also,
6051 implemnted the printing of the SERVER_SIGNOFF info to the
6052 application. Affected file silc/client_ops.c.
6054 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6055 if the deleting was successful. Affected file silcd/idlist.[ch].
6057 * Added support for public key authentication in the connection
6058 authentication protocol in the client library. Affected file
6059 lib/silcclient/protocol.c.
6061 * Changed the server's silc_idlist_get_clients_by_* interface
6062 to support already allocated array so that new entries may be
6063 added to pre-allocated array. Affected file silcd/idlist.[ch].
6064 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6065 and command replies.
6067 * All command reply functions in the server now calls the
6068 pending command callback even if error occured. This way the
6069 error will be delivered to the client as well. Affected files
6070 silcd/command.c and silcd/command_reply.c.
6072 * Fixed INFO command to return local server's info if no server
6073 was provided. Affected file lib/silcclient/command.c.
6075 * Removed RESTART command for good. Updated the code and the
6078 * Rewrote parts of the task system. It is a bit simpler now.
6079 Removed unsued task priorities. The affected files are
6080 lib/silcutil/silctask.[ch].
6082 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Moved the USERS printing from the library to the application.
6085 Affected files lib/silcclient/command.c and silc/client_ops.c.
6087 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6091 * Added channel key re-key support. The re-key is perfomed
6092 only by the router and is done once in an hour. Added `rekey'
6093 field to the SilcChannelEntry in the server. Affected files
6094 silcd/server.c and silcd/idlist.h.
6096 * Added silc_task_unregister_by_context into the file
6097 lib/silcutil/silctask.[ch].
6099 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added SILC_UMODE_GONE mode to indicate when the client is not
6102 present in the SILC network. Added also support to the local
6103 command AWAY that will set this mode. Added support of showing
6104 "xxx is gone" in WHOIS command. The USERS command shows the
6105 gone status as well.
6107 * Fixed setting server and router operator privileges in the
6108 server's UMODE command. Affected file silcd/command.c.
6110 * Merged the SKE KE1 and KE2 payloads into one payload. The
6111 new KE payload is equivalent to the old KE2 payload.
6113 Cleaned up the SKE Start Payload parsing. It now uses the
6114 simple buffer unformatting to do the parsing. A lot faster
6117 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6118 to the SKE that is used to indicate whether both of the SKE
6119 parties should perform authentication. By default only the
6120 responder performs authentication. By setting this flag also
6121 the initiator must do authentication. By default it is unset
6122 since in normal SKE case, client to server connection, only
6123 the responder should do authentication. When doing SKE between
6124 two clients both should perform authentication. Updated the
6125 code and the protocol specs.
6127 * A little fix to IDENTIFY command in the server. Search the
6128 client first by hash not nickname. Affected file is
6131 * Fixed the silc_client_close_connection to support closing
6132 the client to client connections wihtout deleting too much
6133 data. Affected file lib/silcclient/client.c.
6135 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6136 are received if protocol used to be active but is not anymore
6137 the application would crash due to NULL pointer dereference.
6138 Affected files silcd/server.c and lib/silcclient/client.c.
6140 * Added `hash' field to the SilcClientConnection to include
6141 the hash function negotiated in the SKE protocol.
6143 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6144 to set the channel founder authentication data. A client can
6145 claim the founder rights later by providing the authentication
6146 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6147 This way the channel founder can regain the channel founder
6148 privileges even it is left the channel. This works only on
6149 local server and the client must be connected to the same
6150 server to be able to regain the founder rights. Updated the
6151 protocol specs accordingly.
6153 Added support to the CMODE command in the client to set the
6154 founder auth data. Read the README to see how to set it.
6156 Added support to the CUMODE command to claim the founder
6157 rights. Read the README to see how to do it.
6159 Added support for the founder authentication to the Channel
6160 Entry in the server. Affected file silcd/idlist.h.
6162 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6163 server's CMODE command. Affected file silcd/command.c.
6165 * Added the following new functions into lib/silccore/silcauth.[ch]:
6166 silc_auth_get_method and silc_auth_get_data.
6168 * The server now saves the remote hosts public key to the
6169 SilcIDListData pointer. Affected file silcd/protocol.c.
6171 * The normal server now does not remove the channel entry from
6172 the cache if the founder authentication data is set. It used
6173 to remove it if the founder was the last one on the channel on
6174 the server and left the channel. The auth data is saved and
6175 if the channel is re-joined later the old entry is used with
6176 the old auth data. Affected files silcd/command_reply.c and
6179 * Removed the `pkcs' field from the SilcIDListData structure
6180 in the server; it is not used. Affected file silcd/idlist.h.
6182 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Fixed packet processing on slow links. Partial packets were
6185 never re-processed because the incoming data buffer was cleared
6186 by the application. Application must not directly clear the
6187 sock->inbuf, the packet processing routines handle it. Fixed
6188 this in client library and in server.
6190 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Fixed the WHOIS and IDENTIFY send reply function to really
6193 check whether to send list or just one entry. Affected file
6196 * Cleaned up the LEAVE command's channel key distribution. The
6197 affected file silcd/command.c.
6199 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6200 can enforce the channel mode as well. In that case the ID
6201 includes the ID of the server. The code now enforces the
6202 mode change if the router have different mode than the server.
6204 * The notify client operation with CMODE_CHANGE notify can now
6205 return NULL client_entry pointer if the CMODE was not changed
6206 by client. Application must check for this.
6208 * Added <Server ID> argument to INFO command to support server
6209 info fetching by Server ID.
6211 * Added silc_server_announce_get_channel_users to get assembled
6212 packets of channel users of the specified channel. Affected
6213 file silcd/server.[ch].
6215 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6216 was freed underneath the ID Cache.
6218 * Re-announce clients when the server received CHANNEL_CHANGE
6219 notify from the router. Affected file silcd/packet_send.c.
6221 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6224 crashed since it did not handle the fact that there is no cipher
6225 called "3" and didn't check the error condition. Now fixed.
6227 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6228 flag. It can be used to send message requests.
6230 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Implemented the RESTART command in the client.
6234 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6235 notice type messages. Added notice printing to the user
6238 * The channel keys are not re-generated if the channel's mode
6239 is PRIVKEY, ie private key on the channel exists. Affected
6240 files silcd/server.c and silcd/command.c.
6242 * Fixed a little bug in channel message delivery when channel
6243 private keys are set in the server. Affected file is
6244 silcd/packet_send.c.
6246 * Changed the setting on channel->on_channel = TRUE from the
6247 silc_client_save_channel_key to the JOIN command reply. The
6248 key payload is not received if the private channel key is set.
6249 Affected file lib/silcclient/command_reply.c and the
6250 lib/silcclient/client_channel.c.
6252 * When the CMODE_CHANGE notify is sent and the channel private
6253 key mode is removed the channel key must be re-generated in
6254 other cells as well. Added this support for the router in the
6255 silcd/packet_receive.c.
6257 * Added new local command NOTICE to send notice message on
6258 channel. Affected file silc/local_command.[ch].
6260 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Added new local command ME to the client. It is used to send
6263 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6264 some action. Affected file silc/local_command.[ch].
6266 * Changed channel_message and private_message client operations
6267 to deliver the message flags to the application. Added also
6268 the `flags' arguments to the silc_client_send_channel_message
6269 and silc_client_send_private_message functions. Affected file
6272 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Redefined the Private Message Payload to support private message
6275 keys and to support the new private message flags. Updated
6276 the protocol specs. Flags makes it possible to have for example
6277 CTCP style messages.
6279 * Added new type SilcPrivateMessagePayload and defined an API
6280 for it in the lib/silcclient/silcprivate.[ch].
6282 * Tested private message private keys successfully. Tested the
6283 private message key set, unset and list commands with the new
6286 * Redefined the Channel Message Payload to include the channel
6287 message flags (equal with private message flags) to support
6288 for example CTCP style messages.
6290 * Defined some of the message (for channel and private message)
6291 flags. Updated the protocol specs and added the flags to the
6292 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6294 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * Added SilcKeyAgreementStatus type to the key agreement routines
6297 to indicate the current status and error if one occured.
6298 The status types are defined in the lib/silcclient/silcapi.h.
6300 * Added new local command KEY that is used to set and unset private
6301 keys for channels, set and unset private keys for private messages
6302 with remote clients and to send key agreement requests and
6303 negotiate the key agreement protocol with remote client. The
6304 key agreement is supported only to negotiate private message keys,
6305 it currently cannot be used to negotiate private keys for channels,
6306 as it is not convenient for that purpose.
6308 * Fixed a minor pending callback setting bug in the function
6309 silc_client_get_client_by_id_resolve, now the function works.
6310 Affected file lib/silcclient/idlist.c.
6312 * Added function silc_net_get_local_port to get local bound
6313 port by socket. Added to lib/silcutil/silcnet.[ch].
6315 * Added `sockets' and `sockets_count' fields to the SilcClient
6316 object. They hold the sockets of the listenning sockets in
6317 the client. Listenning sockets may be for example the key
6318 agreement server. Affected file lib/silcclient/client.[ch].
6319 Added functions the silc_client_add_socket and the
6320 silc_client_del_socket. They are exported to the application
6323 * Added ~./silc/clientkeys to support other client's public keys.
6325 * Renamed verify_server_key client operation to verify_public_key
6326 and added one argument to indicate the type of the connection
6327 (server, client etc.).
6329 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Added silc_server_connection_auth_request to handle the
6332 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6333 silcd/packet_receive.[ch].
6335 * Added silc_server_send_connection_auth_request into the
6336 silcd/packet_send.c to send the connection auth request packet.
6338 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6341 * Fixed the public key authentication in responder side in the
6342 server. The `auth_data' pointer includes the SilcPublicKey
6343 not the path to the public key. Affected file silcd/protocol.c.
6345 * Implemented the public key authentication in the initiator side
6346 in the server. Affected file silcd/protocol.c.
6348 * Removed the [RedirectClient] config section from the server
6349 configuration. Is not needed and I don't want to implement it.
6351 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Cleaned up the CMODE command in the server. It now works
6354 correctly and supports all the modes defined in the protocol.
6355 Affected file is silcd/command.c.
6357 * Added `hmac_name' field to the SilcChannelEntry in the server
6358 to hold the default HMAC of the channel. It can be set when
6359 creating the channel (with JOIN command). Affected files
6362 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6363 type to indicate the change of the current cipher and hmac
6364 on the channel. Client can safely ignore the <cipher> argument
6365 (if it chooses to do so) since the CHANNEL_KEY packet will
6366 force the channel key change anyway. The <hmac> argument is
6367 important since the client is responsible of setting the new
6368 HMAC and the hmac key into use.
6370 * Fixed the CMODE command in the client library as well.
6372 * Tested CMODE command in router environment successfully.
6374 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Show the version of the remote client (or server) when connecting
6377 to the server. It is logged to the log file. Affected file
6378 is silcd/protocol.c.
6380 * Fixed the KILLED notify handling in the client library. The
6381 client must be removed from all channels when receiving the
6384 Also, do not remove the client entry when giving the KILL
6385 command but when the KILLED notify is received.
6387 * Removed silc_idlist_find_client_by_nickname from the server.
6388 Not needed anymore. Affected files silcd/idlist.[ch].
6390 * Implemented the CHANNEL_CHANGE notify type handling to the
6391 server. Affected file silcd/server.c.
6395 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Added silc_server_send_notify_invite to send the INVITE
6398 notify between routers.
6400 * Implemented the INVITE command correctly to the server.
6402 * Implemented the INVITE notify type handling in the server.
6404 * Implemented the INVITE command to the client library and on the
6407 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Added function silc_server_get_client_resolve to find the
6410 client entry by ID from all ID lists and then resolve it
6411 (using WHOIS) if it cannot be found. Affected file is
6414 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Implemented the BAN command to the client library.
6418 * The JOIN command in the server now checks the invite list
6421 * Changed the silc_command_reply_payload_encode_va and the
6422 silc_command_payload_encode_va to support that if argument is
6423 NULL it ignores and checks the next argument. Affected file
6424 lib/silccore/silccommand.c.
6426 * Added silc_server_send_notify_ban to send the BAN notify
6427 type between routers.
6429 * Chaned the silc_notify_payload_encode to support that if
6430 argument is NULL it ignores and checks the next argument.
6431 Affected file lib/silccore/silcnotify.c.
6433 * Tested ban lists in router environment successfully.
6435 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * Implemented BAN command to the server, in silcd/command.[ch].
6439 * Removed the BAN and INVITE_LIST modes from the CMODE command
6442 * Added function silc_string_match to regex match two strings.
6443 Affected files lib/silcutil/silcutil.[ch].
6445 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Redefined parts of the SilcChannelEntry in the server to support
6448 the new ban and invite lists.
6450 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Redefined the INVITE command. The same command can be used to
6453 invite individuals to the channel but also to manage the invite
6454 list of the channel (to add to and remove from the invite list).
6455 Updated the protocol specs.
6457 * Added new command SILC_COMMAND_BAN that can be used to manage
6458 the ban list of the channel. Updated the protocol specs.
6460 * Removed the channel modes: the SILC_CMODE_BAN and the
6461 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6462 in the CMODE command. The equivalent features are now available
6463 using INVITE and BAN commands. Updated the protocol specs.
6465 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6466 in the network about change in the current ban list. The notify
6467 type is not used by the client.
6469 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6470 support the invite lists.
6472 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Added new function silc_string_regexify that converts string
6475 including wildcard characters into regex string that can
6476 be used by the GNU regex library. Added into the file
6477 lib/silcutil/silcutil.[ch].
6479 Added silc_string_regex_combine to combine to regex strings
6480 into one so that they can be used as one regex string by
6481 the GNU regex library. Added into the file
6482 lib/silcutil/silcutil.[ch].
6484 Added silc_string_regex_match to match two strings. It returns
6485 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6487 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Imported GNU regex to the soruce tree into lib/contrib.
6490 Fixed some compiler warning from the regex.c.
6492 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * Fixed MOTD command in the server to work in router environment.
6496 * Fixed the MOTD command in the client library to support
6497 the server argument in the command.
6499 * Added `nickname_len' argument to the silc_idlist_add_client
6500 in the server, as the `nickname' argument may be binary data
6503 * Added silc_idlist_get_channels to return all channels from
6506 * Implemented LIST command to the server. Affected file is
6509 * Implemented the LIST command to the client library and on the
6512 * Added [<user count>] argument to the LIST command reply.
6513 With private channels the user count is not shown.
6515 * Updated TODO and README.
6517 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * The client entry's data.registered must be TRUE even with
6520 global client entry on global client list. The data.registered
6521 is used to check whether the client is anymore in the network,
6522 for example with WHOWAS command so it must be valid.
6524 * Fixed the WHOWAS command in the server. It now actually works
6525 in router environment. Added function into silcd/command_reply.c
6526 silc_server_command_reply_whowas_save.
6528 * Added silc_idlist_purge function to the silcd/idlist.c
6529 to periodically purge the ID Cache.
6531 * Fixed INFO command in the server. It works now in router
6532 environment. Added <server name> argument to the INFO command
6533 reply. Updated the protocol specs.
6535 * Fixed minor bug in silc_idcache_purge to not purge if the
6536 expire value is zero.
6538 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6539 they were buggy because of the WHOWAS information.
6541 * Fixed local command MSG to handle the async resolving of
6542 the remote client properly. It used to fail the first MSG.
6543 Affected file silc/local_command.c.
6545 * Added `data_len' field to SilcIDCache context.
6547 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Update TODO. Todo in commands in the server.
6551 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6554 used by routers as broadcast packet to inform other routers
6555 about the changed user mode.
6557 Implemented the notify handling in the server. Affected file is
6558 silcd/packet_receive.c. Added the function
6559 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6561 * Added new generic Channel Payload and deprecated the New Channel
6562 Payload. The New Channel Payload is now the generic Channel
6565 * Added new argument `mode' to the silc_server_send_new_channel
6566 as it is required in the Channel Payload now.
6568 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6569 and created a new and real SilChannelPayload to represent the
6570 new generic Channel Payload. Implemented the encode/decode
6571 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6573 * Added silc_server_get_client_channel_list to return the list
6574 of channels the client has joined for WHOIS command reply.
6575 Affected file silcd/server.[ch].
6577 * Implemented the channel list sending in the WHOIS command reply
6578 in server and in the client.
6580 Implemented the channel list displaying on the user interface
6581 as well. Affected file silc/client_ops.c.
6583 * Added silc_channel_payload_parse_list to parse list of Channel
6584 Payloads. It returns SilcDList list of SilcChannelPayloads.
6585 Client for example can use this function to parse the list of
6586 channels it receives in the WHOIS command reply. The caller
6587 must free the list by calling silc_channel_payload_list_free.
6588 Affected files lib/silccore/silcchannel.[ch].
6590 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Added one new argument <user mode> to the WHOIS command reply
6593 to return the mode of the user in SILC. Updated the protocol
6596 Implemented it to the server and client.
6598 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Fixed the mode printing on the user interface on joining.
6601 Affected file silc/client_ops.c.
6603 * Implemented the UMODE command and user modes in general to the
6604 client library and to the user interface.
6606 * Implemented the UMODE command to the server.
6608 * The server now sends UNKNOWN_COMMAND error status if client sends
6609 unknown command. Affected file silcd/command.c.
6611 * All server commands now handle the command identifier the right
6612 way when sending the command reply to the client. The client can
6613 use to identify the command replies with the identifier.
6615 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Added silc_server_get_client_route to resolve the route to
6618 the client indicated by the client ID. Affected file is
6621 * Added silc_server_relay_packet as general function to relay
6622 packet to arbitrary destination. This deprecates functions
6623 like _send_private_message_key, _relay_notify etc. Affected
6624 file is silcd/packet_send.[ch].
6626 Removed silc_server_send_key_agreement,
6627 silc_server_send_private_message_key and
6628 silc_server_packet_relay_notify functions from the file
6629 silcd/packet_send.[ch].
6633 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6634 server. Affected file silcd/packet_receive.[ch].
6636 * Implemented the KILL command to the client. Implemented the
6637 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6638 Affected files lib/silcclient/command[_reply].c and
6639 lib/silcclient/client_notify.c. Implemented the KILL notify
6640 printing in the user inteface.
6642 * Fixed a lot silc_parse_nick memory leaks from the client
6643 library in the file lib/silcclient/command.c.
6645 * Changed the silc_server_send_notify_on_channels's `sender'
6646 argument from SilcSocketConnection to SilcClientEntry to
6647 check the sender as entry and not as connection object and not
6648 to send to the client provided as argument. The affected file
6649 is silcd/packet_send.[ch].
6651 * The notify packets that are destined directly to the client used
6652 to not to be processed by the server. Now changed that and the
6653 server processes all notify packets. After relaying the packet
6654 to the client the notify packet is processed in the server.
6656 * The silc_server_free_client_data now checks whether there is
6657 pending outgoing traffic for the client and purges the data to
6658 the network before removing the client entry.
6660 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6663 an client is killed from the SILC Network. Updated the protocol
6666 Added new function silc_server_send_notify_killed to the
6667 silcd/packet_send.[ch].
6669 * Added function silc_server_packet_relay_notify to relay notify
6670 packets that are destined directly to a client. In this case
6671 the server does not process the notify packets but merely relays
6672 it to the client. Affected file silcd/packet_send.[ch].
6674 Added also silc_server_packet_process_relay_notify to check
6675 whereto relay the notify. Affected file is
6676 silcd/packet_receive.[ch].
6678 * Implemented the KILL command to the server.
6682 * Added the backup schema desgined last fall to the protocol
6683 specs for everyone to see. The specification is in the
6684 *-spec-xx.txt draft and the packet type definitions for the
6685 backup routers is in *-pp-xx.txt draft. Thusly, added also
6686 new packet type SILC_PACKET_CELL_ROUTERS.
6688 * A big security problem in the implementation discovered. The
6689 signoff of an client did not cause new channel key generation
6690 which it of course should've done. The channel keys must be
6691 always re-generated when client leaves (or signoffs) the channel.
6692 The silc_server_remove_from_channels funtion now handles
6693 the channel key re-generation.
6695 * Added `sender' argument to the silc_server_send_notify_on_channels
6696 to not to send the client provided as argument. Affected file
6697 silcd/packet_send.[ch].
6699 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Implemented OPER and SILCOPER commands into the server and
6704 * Added silc_auth_verify and silc_auth_verify_data to verify
6705 the authentication directly from the authentication payload.
6706 It supports verifying both passphrase and public key based
6707 authentication. Affected file lib/silccore/silcauth.[ch].
6709 * Added `hash' field to the SilcIDListData structure. It is the
6710 hash negotiated in the SKE protocol. Affected file is
6713 * Slight redesigning of the SilcAuthPayload handling routines.
6714 Do not send SilcPKCS but SilcPublicKey as argument.
6716 * Implemented the public key authentication support to the
6717 serverconfig. The public key is loaded from the provided path
6718 and saved as authentication data to void * pointer. Thus,
6719 changed the unsigned char *auth_data to void *auth_data;
6721 * Fixed SHUTDOWN command to send the reply before the server
6722 is shutdown. :) Affected file silcd/command.c.
6724 * Fixed fatal bug in CONNECT command. The hostname was invalid
6725 memory and server crashed. Affected file silcd/command.c.
6727 * Fixed fatal bug in CLOSE command. The server_entry became
6728 invalid but was referenced later in the command. Affected file
6731 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6733 * Fixed fatal bug in failure packet handling. Server ignored
6734 the failure and thus crashed when it came.
6738 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6741 that the command may be executed only once in (about) 2 seconds.
6742 The old SILC_CF_LAG flag is same but allows command bursts up
6743 to five before limiting.
6745 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6746 server code. Various commands now includes the CF_LAG_STRICT
6747 flag to disallow any kind of miss-use of the command.
6749 * Fixed the silc_buffer_unformat to not to allocate any data
6750 if the length of the data is zero. It used to allocate the
6751 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6753 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6755 * Changed the format of AdminConnection configuration section
6756 in the server. Added username of the admin to the format.
6757 Affected files silcd/serverconfig.[ch].
6759 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6760 to return admin configuration data by host, username and/or
6763 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Implemented WHOWAS command to the server. Added the functions:
6767 silc_server_command_whowas_parse,
6768 silc_server_command_whowas_send_reply,
6769 silc_server_command_whowas_from_client and
6770 silc_server_command_whowas_from_server
6772 * Added <Client ID> argument to the WHOWAS command reply. Updated
6773 the protocol specs accordingly.
6775 * Implemented WHOWAS command and command_reply to the client
6778 Implemented the WHOWAS printing on the user interface.
6780 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Added new argument to the WHOWAS command reply, the real name.
6783 It is an optional argument. Updated the protocol specs.
6785 * Added SilcIDCacheDestructor callback that is registered when
6786 the SilcIDCache is allocated. The callback is called when
6787 an cache entry in the ID Cache expires, or is purged from the
6788 cache. Added into lib/silccore/idcache.[ch].
6790 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6791 to destruct the client entries when the cache entry expires.
6792 Other ID Cache's in server and in the client library ignores
6795 * If the ID Cache entry's `expire' field is zero then the entry
6796 never expires. Added boolean `expire' argument to the
6797 silc_idcache_add function in the lib/silccore/idcache.[ch].
6798 If it is TRUE the default expiry value is used.
6800 * Added silc_server_free_client_data_timeout that is registered
6801 when client disconnects. By default for 5 minutes we preserve
6802 the client entry for history - for WHOWAS command.
6804 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Added support to the server to enforce that commands are not
6807 executed more than once in 2 seconds. If server receives
6808 commands from client more frequently, timeout is registered
6809 to process the commands. Affected file silcd/command.c.
6810 Added new function silc_server_command_process_timeout.
6812 * Changed NICK_NOTIFY handling in client library to check that
6813 if the client's nickname was changed, so there is no need to
6814 resolve anything from the server.
6816 * Removed error printing from the WHOIS and IDENTIFY commands.
6817 If error occurs then it is ignored silently in the client library.
6818 The application, however, may map the received error to
6819 human readable error string. The application currently maps
6820 the NO_SUCH_NICKNAME error to string.
6822 * Made the command status message public to the application. Moved
6823 them from lib/silcclient/command_reply.c to
6824 lib/silcclient/command_reply.h. The application can map the
6825 received command status to the string with the
6826 silc_client_command_status_message function.
6828 * Added check to the server to check that client's ID is same
6829 as the Source ID in the packet the client sent. They must
6832 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Added dist-bzip hook to the Makefile.am to make bzip2
6835 compressed distributions.
6837 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Server now enforces the maximum length for the nickname and
6840 the channel as protocol specification dictates. 128 bytes for
6841 nickname and 256 bytes for channel name.
6843 * Moved the WHOIS printing to the application. The client libary
6844 does not print out the WHOIS information anymore, the application
6845 must do it. Renamed silc_client_command_reply_whois_print to
6846 the silc_client_command_reply_whois_save.
6848 The client's idle time is also sent to the application now, and
6849 the idle is shown on screen.
6851 * Added silc_client_command_reply_identify_save to save the
6852 received IDENTIFY entries.
6854 * Do not check for channel private keys in message sending and
6855 reception if the channel does not have the PRIVKEY mode set.
6856 Affected file lib/silclient/client_channel.c.
6858 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6861 just surfaced after chaning the JOIN procedure.
6863 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added silc_client_get_clients_by_list to get client entries
6866 from Client ID list, that is returned for example by JOIN
6867 and USERS command replies. The application should use this
6868 function for example when JOIN command reply is received to
6869 resolve the clients already on the channel (library does not
6870 do that anymore as USERS command reply is not used in the JOIN
6871 procedure anymore). Affected files lib/silcclient/silcapi.h and
6872 lib/silcclient/idlist.c.
6874 * JOIN command reply and USERS command reply returns now SilcBuffer
6875 pointers instead of unsigned char pointers when returning
6876 the client list and mode list.
6878 * Added <Client ID> argument to the JOIN command reply, mainly
6879 for the server to identify for which client the command was
6880 originally sent. Updated protocol specs accordingly.
6882 * Added SilcDlist private_key pointer to the SilcChannelEntry
6883 in the client to support the channel private keys. Affected
6884 file is lib/silcclient/idlist.h.
6886 * Added SilcChannelPrivateKey argument to the function
6887 silc_client_send_channel_message so that application can choose
6888 to use specific private ke if it wants to. If it is not provided,
6889 the normal channel key is used, unless private keys are set.
6890 In this case the first (key that was added first) is used
6891 as the encryption key.
6893 * Implemented the support for channel private key handling.
6894 Implemented the following functions:
6896 silc_client_add_channel_private_key,
6897 silc_client_del_channel_private_keys,
6898 silc_client_del_channel_private_key,
6899 silc_client_list_channel_private_keys and
6900 silc_client_free_channel_private_keys
6902 Affected file lib/silcclient/client_channel.c.
6904 * Added the support for the private keys in the channel message
6905 sending and encryption and in the message reception and
6906 decryption. Affected funtions are
6907 silc_client_send_channel_message and silc_client_channel_message.
6909 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Added SKE's key verify callback to the client library's
6912 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6914 * Removed the statement that server (or router) must send USERS
6915 command reply when joining to the channel so that the client
6916 knows who are on the channel. Instead, the client list and
6917 client's mode list is now sent in the JOIN command reply to the
6918 client who joined channel. This is better solution.
6920 * Added function silc_server_get_users_on_channel and function
6921 silc_server_save_users_on_channel to the silcd/server.[ch].
6923 * Removed function silc_server_command_send_users from the
6926 * Do not show topic on the client library anymore. The topic is
6927 sent in the command reply notify to the application and the
6928 application must show the topic now.
6930 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6932 * Added client searching by nickname hash into the IDENTIFY and
6933 WHOIS commands in the server as they were clearly missing from
6934 them. Affected file is silcd/command.c.
6936 * Fixed a bug in private message receiving in the client library.
6937 The remote ID was freed and it wasn't supposed, now it is
6940 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Minor fix to the channel payload; allocate the data area, as it
6943 needs to be of specific length.
6945 * If the key agreement port is zero then the operating
6946 system will define the bound port. Affected files are
6947 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6949 * Added new function silc_channel_payload_decrypt into the file
6950 lib/silccore/silcchannel.[ch].
6952 * Moved the channel message etc, check from silc_packet_decrypt
6953 to applications. The library calls now a generic
6954 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6955 when the packet is either normal or special. This was done to
6956 allow more wide range of checking that was not allowed when
6957 the code was in library. Now applications can do virtually any
6958 checks to the packet and return to the library the decision how
6959 the packet should be processed. Affected files are
6960 lib/silccore/silcpacket.[ch].
6962 Added silc_server_packet_decrypt_check to the server and
6963 silc_client_packet_decrypt_check to the client library.
6965 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6966 to send with specified source and destination information.
6968 * Channel message delivery between routers was broken after the
6969 channel key distribution was fixed earlier. The channel key
6970 was used be to distributed to other routers as well which is not
6971 allowed by the protocol. Now this is fixed and channel keys
6972 really are cell specific and the channel message delivery between
6973 routers comply with the protocol specification.
6975 * Fixed various commands in server to check also the global list
6976 for the channel entry and not just the local list. The affected
6977 file silcd/command.c.
6979 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Added assert()s to buffer formatting and unformatting routines
6982 to assert (if --enable-debug) when error occurs. Affected
6983 file: lib/silcutil/silcbuffmt.c.
6985 * Changed to auto-reconnect to check whether the remote host is
6986 router and register the re-connect timeout if it is. It used
6987 to check that whether we are normal server, but router must do
6988 auto-reconnect with another router as well. Affected file
6991 * Removed the [<key len>] option from CMODE command as the cipher
6992 name decides the key length, nowadays. See the defined ciphers
6993 from the protocol specification.
6995 * Added [<hmac>] option to the CMODE command to define the HMAC
6996 for the channel. Added SILC_CMODE_HMAC channel mode.
6998 * Added [<hmac>] option for the JOIN command so that user can
6999 select which HMAC is used to compute the MACs of the channel
7002 * Added Hmac field to the Channel Message Payload. The integrity
7003 of plaintext channel messages are now protected by computing
7004 MAC of the message and attaching the MAC to the payload. The
7005 MAC is encrypted. Now, it is clear that this causes some
7006 overhead to the size of the packet but rationale for this is that
7007 now the receiver can verify whether the channel message decrypted
7008 correctly and also when private keys are set for the channel the
7009 receiver can decrypt the packet with several keys and check from
7010 the MAC which key decrypted the message correctly.
7012 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7013 lib/silccrypt/silccipher.[ch].
7015 * Added silc_hash_len to return the digest length into the
7016 lib/silcrypt/silchash.[ch].
7018 * Rewrote parts of Silc Channel Payload interface in the
7019 lib/silccore/silcchannel.[ch]. The encode function now also
7020 encrypts the packet and parse function decrypts it.
7022 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7024 * Fixed a minor formatting bug in the SKE's key material processing.
7025 It actually might have processed the keys wrong way resulting
7028 * Redefined the mandatory HMAC algorithms and added new algorithms.
7029 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7030 and hmac-md5 truncated to 96 bits. The mandatory is now
7031 hmac-sha1-96. Rest are optional (including the one that used
7032 to be mandatory). Rationale for this is that the truncated HMAC
7033 length is sufficient from security point of view and can actually
7034 make the attack against the HMAC harder. Also, the truncated
7035 HMAC causes less overhead to the packets. See the RFC2104 for
7038 * Added new [hmac] configuration section. The SKE used to use
7039 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7040 is of course wrong. The official names that must be proposed in
7041 the SKE are the ones defined in the protocol specification
7042 (hmac-sha1-96 for example). The user can configure any hmac
7043 using any hash function configured in the [hash] section. At
7044 least, the mandatory must be configured.
7046 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7048 * Added HMAC list to the SKE proposal list. It has now both
7049 hash algorithm list and HMAC list. This makes the protocol
7050 incompatible with previous versions. The SKE now seems to work
7051 the way it is supposed to work, for the first time actually.
7053 * Defined plain Hash algorithms to the protocol specification.
7056 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Implemented support for key agreement packets into the server.
7059 Added functions silc_server_key_agreement and
7060 silc_server_send_key_agreement. Other than these functions,
7061 server has nothing to do with this packet.
7063 * Added support for private message key packets into the server.
7064 Added functions silc_server_private_message_key and
7065 silc_server_send_private_message_key.
7069 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7070 called in the protocol's final callback instead in the END
7071 protocol state. This makes a little more sense and in the same
7072 time in client we can use the same protocol routines for normal
7073 key exchange and to key agreement packet handling as well.
7075 * Added to both client's and server's KE protocol context the
7076 SilcSKEKeyMaterial pointer to save the key material. We will
7077 bring the key material to the protocol's final callback by doing
7078 this. The final callback must free the key material.
7080 * Added SKE's packet_send callback into client's KE protocol
7081 context so that the caller can choose what packet sending function
7082 is used. This way we can use different packet sending when
7083 doing normal SKE when doing key agreement packet handling (in
7084 the key agreement packet handling we do not want to encrypt
7087 * Implemented the responder side of the key agreement routines
7088 in the client. The client can now bind to specified port and
7089 accept incoming key negotiation. The key material is passed
7090 to the application after the protocol is over.
7092 * Implemented the processing of incoming Key Agreement packet
7093 in the client. Added function silc_client_key_agreement to
7096 * Implemented the intiator side of the key agreement routines
7097 in the client. The client can now initiate key agreement with
7098 another remote client. The key material is passed to the
7099 application after the protocol is over.
7101 * Created client_keyagr.c to include all the key agreement
7104 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7105 SILC_TASK_CALLBACK except that it is not static.
7107 * Created client_notify.c and moved the Notify packet handling
7108 from the client.[ch] into that file.
7110 * Created client_prvmsg.c and moved all private message and
7111 private message key routines from the client.[ch] into that file.
7113 * Create client_channel.c and moved all channel message and
7114 channel private key routines from the client.[ch] into that file.
7116 * Changed silc_client_get_client_by_id_resolve to resolve with
7117 WHOIS command instead of IDENTIFY command, in the file
7118 lib/silclient/idlist.c.
7120 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Implemented the SKE's responder side to the Client library.
7124 * When FAILURE is received to the protocol do not trust it
7125 blindly. Register a timeout to wait whether the remote closes
7126 the connection as it should do it, only after that process the
7127 actual failure. This was changed to both client and server.
7129 * Added client_internal.h to include some of the structures
7130 there instead of client.h in lib/silcclient/.
7132 * Added function silc_task_unregister_by_callback to unregister
7133 timeouts by the callback function.
7135 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Some "Incomplete WHOIS info" errors has been appearing on the
7138 log files. Took away the entry->userinfo check from WHOIS
7139 reply sending. The entry->userinfo is now " " if client did not
7140 provide one. I thought this was fixed earlier but something
7141 is wrong still. Let's see if the error still appears.
7143 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7145 * Fixed a minor bug in the login when the channel key is
7146 re-generated in the server. It used to generate the key in
7147 wrong order and thus caused problems in the channel traffic.
7149 * Fixed a minor bug in channel key distsribution after
7150 KICK command. The key was not sent to the router even though
7153 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Added silc_ske_process_key_material_data as generic routine
7156 to process any key material as the SILC protocol dictates. The
7157 function is used by the actual SKE library but can be used by
7158 applications as well. This relates to the private message keys
7159 and the channel private keys since they must be processed the
7160 same way the normal SILC session keys. The protocol dictates
7161 this. Affected files: lib/silcske/silcske.[ch].
7163 Added also silc_ske_free_key_material to free the
7164 SilcSKEKeyMaterial structure.
7166 * Defined silc_cipher_set_key function to set the key for
7167 cipher without using the object's method function. The affected
7168 files: lib/silccrypt/silccipher.[ch].
7170 * Implemented silc silc_client_add_private_message_key,
7171 silc_client_add_private_message_key_ske,
7172 silc_client_del_private_message_key,
7173 silc_client_list_private_message_keys and
7174 silc_client_free_private_message_keys functions in the
7177 Added functions silc_client_send_private_message_key to send
7178 the Private Message Key payload and silc_client_private_message_key
7179 to handle incoming Private Message Key payload.
7181 * Added Cipher field to the Private Message Key payload to set
7182 the cipher to be used. If ignored, the default cipher defined
7183 in the SILC protocol (aes-256-cbc) is used.
7185 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Removed lib/silcclient/ops.h file.
7189 Redefined parts of the SILC Client Library API. Created new
7190 file silcapi.h that deprecates the ops.h file and defines the
7191 published Client Library API. Defined also private message key
7192 API and channel private key API into the file.
7194 This is the file that the application must include from the
7195 SILC Client Library. Other files need not be included by
7196 the application anymore.
7198 * Added new key_agreement client operation callback and also
7199 defined the Key Agreement library API for the application.
7201 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7204 is used by clients to request key negotiation between another
7205 client in the SILC network. If the negotiation is started it
7206 is performed using the SKE protocol. The result of the
7207 negotiation, the secret key material, can be used for example
7208 as private message key.
7210 Implemented the Key Agreement payload into the files
7211 lib/silccore/silauth.[ch].
7213 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7215 * Redefined ciphers for the SILC protocol. Added some new ciphers
7216 and defined the key lengths for the algorithms. Changed the
7217 code accordingly. The default key length is now 256 bits.
7219 * Fixed SKE key distribution function silc_ske_process_key_material
7220 when the key length is more than 128 bits. The default key
7221 length in SILC is now 256 bits.
7223 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7224 to indicate unsupported algorithm.
7226 * Renamed rijndael.c to aes.c and all functions as well.
7228 * Fixed a long standing channel key setting bug in client library.
7229 Weird that it has never surfaced before.
7231 * Fixed bug in channel deletion. If the entire channel is removed
7232 then it must also delete the references of the channel entry
7233 from the client's channel list as the client's channel entry and
7234 the channel's client entry share same memory.
7236 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Implemented CONNECT and SHUTDOWN commands in the client.
7240 * Implemented CLOSE command to the client.
7242 * Added the function silc_idlist_find_server_by_name into the
7243 files silcd/idlist.[ch].
7245 Added the function silc_idlist_find_server_by_conn into the
7246 files silcd/idlist.[ch].
7248 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * DIE command was renamed to SHUTDOWN. Updated the both code
7253 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7254 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7256 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7259 * Added function silc_server_create_connection function to create
7260 connection to remote router. My server implementation actually
7261 does not allow router to connect to normal server (it expects
7262 that normal server always initiates the connection to the router)
7263 so the CONNECT command is only good for connecting to another
7266 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7269 or some other client was kicked from the channel.
7271 Implemented the handling of the notify type to both client
7274 Implemented silc_server_send_notify_kicked to send the KICKED
7275 notify. It is used to send it to the server's primary router.
7277 * Implemented the KICK command into server and client.
7279 * Added `query' argument to the silc_idlist_get_client function
7280 to indicate whether to query the client from server or not if
7283 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7284 to indicate that the client is not channel founder.
7288 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Removed the rng context from SilcPacketContext structure and
7291 changed that the packet routine uses the Global RNG API.
7293 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Added support for quit message that client can "leave" on the
7296 channel when it quits the SILC. It is ditributed inside the
7297 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7299 Added silc_server_free_client_data that will take the
7300 signoff message as argument.
7302 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7304 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7306 * Updated parts of the protocol specification to keep it up
7309 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7311 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7312 payloads in one packet.
7314 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7315 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7316 use now the new List flag.
7318 * Also deprecated the following packet types: REPLACE_ID,
7319 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7321 * Added list support for Notify packet in server.
7323 * Added silc_server_send_notify_channel_change to send the
7324 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7325 the silc_server_send_replace_id.
7327 * Added silc_server_send_notify_nick_change to send the
7328 NICK_CHANGE notify type. Deprecates the function
7329 silc_server_send_replace_id.
7331 * Added silc_server_send_notify_join to send the JOIN notify type.
7332 Deprecates the function silc_server_send_new_channel_user.
7334 * Added silc_server_send_notify_leave to send LEAVE notify type.
7335 Deprecates the function silc_server_send_remove_channel_user.
7337 * Added silc_server_send_notify_cmode and
7338 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7339 types. Deprecates the silc_server_send_set_mode function.
7341 * Added SERVER_SIGNOFF notify type to indicate that server has
7342 quit. This means that all clients on the channel from that
7343 server will drop. This can be also used when netsplit happens.
7345 Deprecated REMOVE_ID packet type since it is not needed anymore
7348 Added silc_server_send_notify_server_signoff to send the
7349 SERVER_SIGNOFF notify type. Deprecates the function
7350 silc_server_send_remove_id.
7352 Added also silc_server_send_notify_signoff to send the
7353 SIGNOFF notify type.
7355 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7356 SILC protocol from this day on. Changed the protocol
7357 specification as well.
7359 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7360 notify type. It is used between routers to notify about
7361 topic changes on a channel.
7363 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7366 * Partly updated the protocol specification to comply with the
7367 changes now made. It is still though a bit outdated.
7369 * The JOIN notify type now takes one extra argument <Channel ID>.
7370 The packet used to be destined to the channel but now the
7371 JOIN type may be sent as list thus it is impossible to
7372 destine it to any specific channel. By adding this argument
7373 it is again possible.
7375 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7377 * Added CREDITS file. The CHANGES and CREDITS file will appear
7378 in the distribution as well.
7380 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7383 types in the server's silcd/packet_receive.c.
7385 * Implemented CMODE and CUMODE to work in router environment.
7387 * Fixed minor encoding and decoding buglet from the
7388 lib/silccore/silcmode.c.
7390 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7393 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7395 * Changed all SilcConfigServer* and silc_config_server* to
7396 SilcServerConfig* and silc_server_config*, respectively.
7399 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Associated the ID (client or server ID) to the Authentication
7402 Payload to avoid any possibility of forging. Updated the
7403 protocol specification and the code accordingly.
7405 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7407 * The RSA key length is now save to the RsaKey context in the
7408 key generation process in lib/silccrypt/rsa.c. The key length
7409 is now used to figure out the maximum size of the block allowed
7410 to be encrypted/signed.
7412 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7413 is equivalent to the silc_mp_mp2bin but does not allocate any
7416 * Changed silc_mp_mp2bin API to take length argument. If it is
7417 non-zero then the buffer is allocated that large. If zero, then
7418 the size is approximated using silc_mp_sizeinbase, which however
7421 * Created Global RNG API which is global RNG that application can
7422 initialize. After initializing, any routine anywhere in the
7423 code (including library) can use RNG without allocating a new
7424 RNG object. This was done to allow this sort of use of the
7425 RNG in code that has no chance to allocate RNG object. All
7426 applications currently allocate this and many routines in the
7427 library use this. Affected file lib/silccrypt/silcrng.[ch].
7429 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7430 it to use the Global RNG API.
7432 * Defined Authentication Payload into protocol specification that
7433 is used during SILC session to authenticate entities. It is
7434 used for example by client to authenticate itself to the server
7435 to obtain server operator privileges.
7437 Implemented this payload into the lib/silccore/silcauth.[ch].
7438 Implemented also routines for public key based authentication
7439 as the new protocol specification dictates.
7441 Moved definitions of different authentication methods from
7442 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7444 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7445 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7446 silc_pkcs_verify_with_hash functions into the file
7447 lib/silccrypt/silcpkcs.[ch].
7449 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7451 * The client entry's userinfo pointer must be always valid.
7452 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7453 will fail since it requires the userinfo. Now, the userinfo
7454 is allocated as "" if actual userinfo does not exist. Actually,
7455 it must exist and it is totally Ok to drop client connections
7456 that does not announce the userinfo. However, we will make
7457 this workaround for now.
7459 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7460 to return the remote port by socket.
7462 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7465 SILC_SERVER_PENDING_EXEC and added an new macro
7466 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7467 data or when error occurs while processing the pending command.
7469 Added new argument `destructor' into silc_server_command_pending
7470 and to the SilcServerCommandPending object. This destructor is
7471 now called after calling the pending callback or if error occurs
7472 immediately. If error occurs the actual pending callback won't
7473 be called at all - only the destructor. The destructor may be
7474 NULL if destructor is not needed.
7476 All this applies for client library code as well. Similar
7477 changes were made there as well for the pending commands.
7479 In the client, the application must now allocate the
7480 SilcClientCommandContext with the silc_client_command_alloc
7483 * Added reference counter to the SilcServerCommandContext. Added
7484 function silc_server_command_alloc and silc_server_command_dup
7487 Same type of functions added to the client library for the same
7490 * Removed the cmd_ident from IDListData away since it is now
7491 global for all connections. It is the command identifier used
7492 in command sending and with pending commands. The affected file
7495 * Added reference counter to the SilcSocketConnection objecet to
7496 indicate the usage count of the object. The object won't be
7497 freed untill the reference counter hits zero. Currently only
7498 server uses this, and client ignores it. The client must be
7499 set to use this too later. The affected files are
7500 lib/silccore/silcsockconn.[ch]. Added also the function
7501 silc_socket_dup to increase the reference counter.
7503 This was mainly added because it is possible that the socket
7504 is removed underneath of pending command or other async
7505 operation. Now it won't be free'd and proper DISCONNECTING
7506 flags, etc. can be set to avoid sending data to connection that
7507 is not valid anymore.
7509 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7510 the connection. After that it sets SILC_SET_DISCONNECTED.
7511 It is, however, possible that the socket data is not still freed.
7512 The silc_server_packet_process now checks that data is not
7513 read or written to connection that is DISCONNECTED. The socket
7514 get's freed when the reference counter hits zero.
7516 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7518 * Changed the client operation API: channel_message operation's
7519 `sender' is now the client entry of the sender, not the nickname
7520 and the `channel' is the channel entry, not the channel name.
7522 In the private_message operation the `sender' is now also the
7523 client entry of the sender not the nickname.
7525 Affected file is lib/silcclient/ops.h and all applications
7526 using the client operations.
7528 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7530 * Moved the calling of ops->connect() from connect_to_server_final
7531 into receive_new_id functin since that is the point when the
7532 client is actually allowed to send traffic to network. The
7533 affected file is lib/silcclient/client.c.
7535 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7538 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7539 (if needs broadcasting) instead of broadcasting the packets one
7540 by one which would make a burst in the network traffic.
7542 * Added `broadcast' argument to the functions in silcd/server.[ch]
7543 silc_server_create_new_channel[_with_id] to indicate whether
7544 to send New Channel packet to primary router.
7546 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7548 * Added new function into the silcd/server.[ch] files:
7549 silc_server_create_new_channel_with_id to create new channel with
7550 already existing Channel ID.
7552 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7553 lib/silccore/silcpacket.h. This packet is used t send list of
7554 Set Mode payloads inside one packet. Server uses this to set
7555 the modes for the channels and clients on those channels, that it
7556 announced to the router when it connected to it. The protocol
7557 specification has been updated accordingly.
7559 * The silc_server_new_channel did not handle the packet coming
7560 from normal server as it normally does not send that. However,
7561 when it announces its channels it does send it. Implemented
7562 the support for that.
7564 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7565 into the file lib/silccore/id.h.
7567 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7569 * Fixed memory leaks in the functions silc_idlist_del_client,
7570 silc_idlist_del_channel and silc_idlist_del_server in the file
7571 silcd/idlist.c. All of those leaked like a sieve.
7573 * Fixed some small memory leaks in the client's function
7574 silc_client_notify_by_server.
7576 * Added functions into silcd/server.c: silc_server_announce_clients,
7577 silc_server_announce_channels and silc_server_announce_server.
7578 These functions are used by normal and router server to announce
7579 to its primary router about clients, channels and servers (when
7580 router) that we own. This is done after we've connected to the
7583 These functions effectively implements the following packet types:
7584 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7585 and SILC_PACKET_NEW_ID_LIST.
7587 * Added new functions into the silcd/packet_receive.[ch]:
7588 silc_server_new_id_list, silc_server_new_channel_list and
7589 silc_server_new_channel_user_list to handle the incoming
7590 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7592 * Added support of changing Channel ID in the function
7593 silc_server_replace_id. If the server that announces a channel
7594 to the router already exists in the router (with same name but
7595 with different Channel ID), router is responsible to send
7596 Replace ID packet to the server and force the server to change
7597 the Channel ID to the one router has.
7599 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7600 client that the Channel ID has been changed by the router. The
7601 normal server sends this to the client. Client must start using
7602 the new Channel ID as the channel's ID.
7604 Implemented handling of this new type into lib/silcclient/client.c
7605 into the function silc_client_notify_by_server.
7607 * Added new function silc_idlist_replace_channel_id into the files
7608 silcd/idlist.[ch] to replace the Channel ID.
7610 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Call silc_server_command_identify_check always when processing
7613 the IDENTIFY command in silcd/command.c
7615 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7618 send keepalive packets. The packet can be sent by clients,
7619 servers and routers.
7621 Added function silc_socket_set_heartbeat into the file
7622 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7623 If not set, the heartbeat is not performed. The actual
7624 heartbeat is implemented in the low level socket connection
7625 library. However, application is responsible of actually
7628 Added silc_server_send_heartbeat to send the actual heartbeat
7629 packet into silcd/packet_send.[ch]. Server now performs
7630 keepalive with all connections.
7632 * Added silc_task_get_first function into lib/silcutil/silctask.c
7633 to return the timeout task with shortest timeout. There was a bug
7634 in task unregistration that caused problems. TODO has been
7635 updated to include that task system must be rewritten.
7637 * The client library will now resolve the client information when
7638 receiving JOIN notify from server for client that we know but
7639 have incomplete information.
7641 * Rewrote parts of silc_server_remove_from_channels and
7642 silc_server_remove_from_one_channel as they did not remove the
7643 channel in some circumstances even though they should've.
7645 * Encryption problem encountered in server:
7647 The LEAVE command used to send the Channel Key packet to the
7648 router immediately after generating it. However, the code
7649 had earlier sent Remove Channel user packet but not immediately,
7650 ie. it was put to queue. The order of packets in the router
7651 was that Channel Key packet was first and Remove Channel User
7652 packet was second, even though they were encrypted in the
7653 reverse order. For this reason, MAC check failed. Now, this
7654 is fixed by not sending the Channel Key packet immediately but
7655 putting it to queue. However, this is more fundamental problem:
7656 packets that are in queue should actually not be encrypted
7657 because packets that are sent immediately gets encrypted
7658 actually with wrong IV (and thus MAC check fails). So, packets
7659 that are in queue should be encrypted when they are sent to
7660 the wire and not when they put to the queue.
7662 However, the problem is that the current system has not been
7663 designed to work that way. Instead, the packet is encrypted
7664 as soon as possible and left to the queue. The queue is then
7665 just purged into wire. There won't be any fixes for this
7666 any time soon. So, the current semantic for packet sending
7669 o If you send packet to remote host and do not force the send
7670 (the packet will be in queue) then all subsequent packets to the
7671 same remote host must also be put to the queue. Only after the
7672 queue has been purged is it safe again to force the packet
7675 o If you send all packets immediately then it safe to send
7676 any of subsequent packets through the queue, however, after
7677 the first packet is put to queue then any subsequent packets
7678 must also be put to the queue.
7680 Follow these rules and everything works fine.
7682 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7684 * Added new function silc_server_remove_clients_by_server to
7685 remove all client entries from ID list when the server connection
7686 is lost. In this case it is also important to invalidate all
7687 client entires as they hold the invalid server entry. This
7688 fixes fatal bug when server has lost connection and will reconnect
7691 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7693 * Made some sanity checks to silc_server_daemonise like to check
7694 whether the requested user and group actually exists.
7696 * Added sanity check to SKE's silc_ske_responder_finish to check
7697 that the public and private key actually is valid.
7699 * Invalidate the client's nickname when receiving Replace ID
7700 packet and the Client ID is being replaced. This means that the
7701 server will query the nickname if someone needs it (client)
7704 * Sort the ID Cache in client library when the ID Cache data
7705 has changed (needs sorting).
7707 * Do not allow for SILC client to create several connections to
7708 several servers. The client does not support windows right now
7709 and generating multiple connections causes weird behaviour.
7711 Irssi-silc client does support windows and can handle several
7712 connections without problems, see: www.irssi.org and SILC plugin.
7714 * Fixed some places where client was added to the IDList. The
7715 rule of thumb is following (in order to get everything right):
7716 If the client is directly connected local client then the
7717 `connection' argument must be set and `router' argument must be
7718 NULL to silc_idlist_add_client function. If the client is not
7719 directly connected client then the `router' argument must
7720 bet set and the `connection' argument must be NULL to the
7721 silc_idlist_add_client function.
7723 * The funtion silc_server_packet_send_local_channel actually did
7724 not check whether the client was locally connected or not. It
7725 does that now. Fixed a bug related to LEAVE command.
7727 * Fixed Remove Channel User payload parsing bug in server's
7728 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7730 * The server's silc_server_save_channel_key now checks also the
7731 global ID list for the channel as it might not be in the local
7732 list. Fixed a bug related to LEAVE command.
7734 * Is this the end of the [<unknown>] buglet that has been lurking
7735 around for a long time? A little for loop fix in server's
7736 silc_server_command_whois_parse that is used by both IDENTIFY
7737 and WHOIS command. At least, this was a clear bug and a cause
7738 of one type of [<unknown>] buglet.
7740 * WHOIS and IDENTIFY commands call the function
7741 silc_server_command_[whois/identify]_check function even if
7742 we are not router server.
7744 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7746 * Added --with-gmp configuration option. If set the GMP
7747 is always compiled in the SILC source tree. If not set then
7748 it is checked whether the system has the GMP3 installed. If
7749 it has then the GMP won't be compiled (the system's headers
7750 and library is used), if it doesn't have it then the GMP is
7751 compiled in the SILC source tree.
7753 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * Changed RSA private exponent generation to what PKCS #1
7756 suggests. We try to find the smallest possible d by doing
7757 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7758 not security fix but optimization.
7760 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7762 * Added new config entry [Identity] to fork the server and run
7763 it as specific user and group. A patch from Bostik.
7765 * Imported Dotconf configuration library into lib/dotconf.
7766 This will be used to create the SILC configuration files later.
7767 It will appear in the distsribution after this commit.
7769 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * A big code auditing weekend happening. Auditing code for
7772 obvious mistakes, bugs and errors. Also, removing any code
7775 Removed files for being obsolete:
7777 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7778 inline in the file lib/silcutil/silcbuffer.h)
7780 o lib/silcutil/silcbufutil.c (the header has inline versions)
7782 Changed code to fix possible error conditions:
7784 o The buffer formatting routines now check that the destination
7785 buffer really has enough space to add the data. This applies for
7786 both buffer formatting and unformatting
7787 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7788 unformatting was changed to accomodate following rules:
7789 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7790 sent to the function while XXX_*STRING will not allocate or copy
7791 the data into the buffer. Instead it sets the pointer from the
7792 buffer into the pointer sent as argument (XXX_*STRING used to
7793 require that the pointer must be allocated already). This change
7794 makes this whole thing a bit more consistent and more optimized
7795 (note that the data returned in the unformatting with XXX_*STRING
7796 must not be freed now). The routines return now -1 on error.
7798 o Tried to find all code that use buffer_format and buffer_unformat
7799 and added return value checking to prevent formatting and
7800 especially unformatting errors and possible subsequent fatal
7803 o Changed ske->x and ske->KEY to mallocated pointers in
7804 lib/silcske/silcske.h. Fixed possible data and memory leak.
7806 o Added return value checking to all *_parse* functions. Fixed
7807 many memory leaks as well.
7809 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7810 so that buffer overflows would not happen. All code now also
7811 checks the return value as it can fail.
7813 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7815 * Added reconnection support to server if the normal server looses
7816 its connection to the router (for example if router is rebooted).
7817 The server performs normal reconnection strategy implemented
7818 to the server. Affected file silcd/server.c.
7820 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7822 * Added new packet type SILC_PACKET_SET_MODE that is used to
7823 distribute the information about changed modes (for clients,
7824 channels and clients channel modes) to all routers in the
7825 network. Updated the protocol specification accordingly.
7827 Added functions into silcd/packet_send.c and
7828 silcd/packet_receive.c: silc_server_send_set_mode,
7829 silc_server_set_mode.
7831 Added new files silcmode.[ch] into lib/silccore that implements
7832 the encoding and decoding of Set Mode Payload. Added new type
7833 SilcSetModePayload. Moved the definitions of different modes
7834 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7836 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7838 * Oops, a little mistake in server's connection authentication
7839 protocol. The protocol is not ended with FAILURE but with
7840 SUCCESS if the authentication is Ok. :) Affected file is
7843 * Implemented NICK_CHANGE notify handling in server in the file
7844 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7845 the local clients on the channel. After the changing nickname
7846 in router environment snhould work and the [<unknown>] nickname
7847 should appear no more.
7849 The silc_server_replace_id function that receives the Replace ID
7850 payload now sends the NICK_CHANGE notify type also in the file
7851 silcd/packet_receive.c
7853 * Changed WHOIS and IDENTIFY command to support the maximum amount
7854 of arguments defined in protocol specs (3328 arguments). This
7855 fixed a bug that caused problems when there were more than three
7858 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Added extra parameter, command identifier, to the
7861 silc_client_send_command so that explicit command identifier
7864 Changed that ID list routines uses specific command identifier
7865 when sending WHOIS/IDENTIFY requests to the server so that they
7866 can be identified when the reply comes back.
7868 Affected files lib/silcclient/command.[ch],
7869 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7871 * Added `sender' argument to silc_server_packet_send_to_channel
7872 to indicaet the sender who originally sent the packet to us
7873 that we are now re-sending. Ignored if NULL. Affected file
7874 silcd/packet_send.[ch].
7876 * Added some server statistics support in silcd/server_internal.h
7877 SilcServerStatistics structure and around the server code. Also
7878 send some nice statistics information when client is connecting
7881 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7883 * Fixed channel ID decoding in server's JOIN command reply in
7884 silcd/command_reply.c
7886 * Fixed braodcasting of replace ID payload to not to send it if
7887 we are standalone server in silcd/packet_receive.c.
7889 * Fixed all channel message sending routines to not to send
7890 packets to clients that has router set, since they are routed
7891 separately in the same function earlier. Affects file
7892 silcd/packet_send.c and all channel packet sending functions.
7894 * In USERS reply, res_argv[i] are not allocated, the table
7895 is allocated. Thus changed that free the table, not its
7898 * In server's whois_check and identify_check if the client is
7899 locally connected do not send any WHOIS commands - they are not
7902 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7904 * Fixed some minor bugs in client when sending WHOIS command. The
7905 arguments was in wrong order.
7907 * Removed statis function add_to_channel from server in
7908 silcd/command.c that was previously used with the joining but
7911 * Tested USERS command in router environment successfully with two
7912 routers, two servers and two clients.
7914 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7916 * Reorganized the USERS command and command reply in client library
7917 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7918 When the command is given by user we register a pending command
7919 callback that will reprocess the command after the reply has been
7920 received from the server. When reprocessing the packet we then
7921 display the information. Thus, the USERS information is displayed
7922 now in the command callback instead of in the command reply
7923 callback. The processing of the command is same as previously
7924 when server has sent the command reply in the JOINing process.
7926 * Added to USERS command in silcd/command_reply.c to join the client,
7927 we didn't use to know about, to the channel after we've created
7928 a client entry for it. Also, for clienet we did know already still
7929 check whether it is on the channel or not and add it if not.
7931 * Removed silc_server_command_join_notify as the function and its
7934 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7936 * Changed the client's pending command handling to the same as the
7937 server's pending command handling. It is also now possible to
7938 execute command reply functions from other command reply
7939 function as the function callbacks for commands and command
7940 replies are one and same. The pending commands are not static
7941 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7942 in client connection context. Thus, pending commands are server
7943 connection specific as it is convenient.
7945 Changed the function silc_client_command_pending and
7946 silc_client_command_pending_del and added new function
7947 silc_client_command_pending_check. Removed the
7948 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7951 * Added cmd_ident, current command identifier, to the client
7952 connection context in lib/silcclient/client.h to keep track on
7953 command identifiers used in command sending. Client's command reply
7954 function handling now supports the mandatory command identifiers.
7956 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7957 funtions in client to fully support pending command callbacks.
7959 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7960 as one of the arguments to the application in the command reply
7963 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7964 before first releasing SILC but came back. Now it is removed again
7965 and should come back nomore. The FORWARDED flag was used only
7966 by the JOINing procedure by forwarding the command packet to router.
7967 Now, the JOINing procedure has been changed to more generic (due
7968 to various router environment issues) and FORWARDED is not needed
7969 anymore for anything. The protocol specification is yet to be
7972 Now, removed silc_server_packet_forward from server and the flag
7973 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7975 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Renamed NAMES command to USERS command. The NAMES was named that
7978 due to historical reasons. Now it is renamed. Also, rewrote
7979 parts of the USERS command. The nickname list is not sent anymore
7980 by the server. Only Client ID and mode lists are sent in the USERS
7981 command. Changed this also to the protocol specification.
7983 The client now resolves the names and stuff after it receives
7984 the USERS list from the server when joining to the channel.
7986 * WHOIS and IDENTIFY commands has been changed to support multiple
7987 Client ID's per command. One can now search for multiple users
7988 in the network by sending only one WHOIS or IDENTIFY command.
7989 Changed the code and the protocol specifications.
7991 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7992 uses silc_server_command_whois_parse to parse the request. */
7994 * If normal server, do not parse the WHOIS and IDENTIFY requests
7995 before sending it to the router. Saves some time.
7997 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7999 * Fixed JOIN command on client library. Wrong number of arguments
8000 used to crash the client.
8002 * Added silc_server_channel_has_global function to check whether
8003 channel has global users or not.
8005 * Added silc_server_channel_has_local function to check whether channel
8006 has locally connected clients on the channel.
8008 * The silc_server_remove_from_one_channel now checks whether the
8009 channel has global users or not after given client was removed from
8010 the channel. It also checks whether the channel has local clients
8011 on the channel anymore. If it does not have then the channel entry
8012 is removed as it is not needed anymore.
8014 * The silc_server_notify now checks on JOIN notify whether the joining
8015 client is one of locally connected or global. If it is global then
8016 the channel has now global users on the channel and that is marked
8017 to the channel entry. Also, it now saves the global client to
8018 global list who is joining and JOINs it to the channel. This is
8019 for normal server, that is.
8021 Changed silc_server_send_notify_on_channel,
8022 silc_server_packet_relay_to_channel and
8023 silc_server_packet_send_to_channel check if we are normal server
8024 and client has router set (ie. global client) do not send the
8025 message to that client, as it is already routed to our router.
8027 * Implemented LEAVE notify type handling in silc_server_notify
8030 * Tested LEAVE command in router environment successfully. Tested
8031 with two routers, two servers and two clients.
8035 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8037 * Implemented SIGNOFF notify type handling in silc_server_notify
8040 * silc_server_remove_id now removes the client entry from all channels
8041 it has joined and thusly sends SIGNOFF notify type.
8043 * Rewrote the NAMES list generation in server by removing two excess
8044 loops. The lists are created now inside one loop.
8046 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8048 * silc_server_remove_channel_user checks now also global list
8049 for channel and client.
8051 * silc_server_new_channel_user checks now both local and global
8052 list for channel and client. Fixed a bug in client id decoding.
8053 Used to decode wrong buffer.
8055 * silc_server_channel_message checks now both local and global
8056 list for channel entry.
8058 * Tested channel joining (hence JOIN) in router environment
8059 successfully. Tested with two routers, two servers and two
8062 * Tested channel message sending in router environment successfully.
8064 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8066 * Added silc_server_save_channel_key into server.[ch] to save the
8067 received channel key in Channel Key payload processing. It is
8068 also used in JOIN command reply handling.
8070 Equivalent function silc_client_save_channel_key added into
8071 client.[ch] into client library.
8073 * Changed JOIN command reply to send information whether the channel
8074 was created or not (is existing already) and the channel key
8075 payload. Changed protocol specs accordingly.
8077 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8078 the request was sent by ID and not by nickname. Crashed on
8081 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8083 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8084 now correctly save the received data.
8086 * silc_server_free_sock_user_data now notifies routers in the
8087 network about entities leaving the network.
8089 At the same time implemented functions silc_server_remove_id
8090 and silc_server_send_remove_id to receive and send REMOVE_ID
8091 packets. The packet is used to notify routers in the network
8092 about leaving entities. The ID removed will become invalid in
8095 * Added function silc_idlist_del_server into server. Removes and
8096 free's server entry from ID list.
8098 * silc_server_private_message function now checks, if we are router,
8099 that the destination ID really is valid ID, naturally.
8101 * In router when NEW_ID packet is received (for new client) the
8102 hash of the Client ID is saved in the ID Cache but the
8103 client->nickname is set to NULL, instead of putting the hash
8106 IDENTIFY command now also checks that client->nickname must be
8107 valid. If it is not if will request the data from the server who
8108 owns the client. Added new function
8109 silc_server_command_identify_check.
8111 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8112 to set the command to already allocated Command Payload.
8114 * Tested private message sending in router environment with two
8115 routers, two servers and two clients. Fixed minor bugs and now
8118 * Fixed segfault from client's NAMES command. Used to crash if
8121 * Forwarded packets must not be routed even if it is not destined
8122 to the receiver. Changed server code comply with this.
8124 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8126 * Added `require_reverse_mapping' boolean value to ServerParams
8127 structure. If TRUE (not default) the server will require that
8128 the connecting host has fully qualified domain name.
8130 If the reverse mapping is not required and hostname could not be
8131 found the IP address is used as hostname.
8133 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8135 * Implemented version string checking to both client and server.
8136 The check is incomplete currently due to the abnormal version
8137 strings used in development version of SILC.
8139 * Changed all command functions in server to use the new
8142 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8144 * Changed char *data to unsigned char *data in ID Cache system to
8145 support binary data as ID Cache data. Changed code to support
8146 binary data in lib/silccore/idcache.c.
8148 * Renamed silc_server_packet_relay_command_reply to
8149 silc_server_command_reply as it is normal packet receiving
8150 function. Rewrote the function to accept command replys for
8151 servers and not only for clients.
8153 * Mark remote router always as registered server if we are connecting
8154 to it. Otherwise, commands sent by the router to us are ignored.
8156 * All ID List find routines now returns the ID Cache Entry pointer
8157 as well if requested.
8159 * WHOIS command works now in router environment, tested with two
8160 routers, two servers and two clients.
8162 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8163 in router environment (as it is almost equivalent to WHOIS) but
8164 hasn't been tested thoroughly. Added new functions:
8166 silc_server_command_identify_parse
8167 silc_server_command_identify_send_reply
8168 silc_server_command_identify_from_client
8169 silc_server_command_identify_from_server
8171 * Disabled route cache adding because adding two different ID's with
8172 same IP replaces the old cache entry thus giving wrong route.
8173 The entry->router->connection is always the fastest route anyway
8174 so route cache may not be needed. Of course, new routes maybe
8175 established after receiving the ID when the entry->router->connection
8176 might not be anymore the most optimal.
8178 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8180 * Add route cache for received ID for fast routing.
8182 * Added silc_server_packet_route to route received packet on router
8183 that is not destined to us.
8185 * Renamed silc_server_get_route to silc_server_route_get.
8187 * Added id_string and id_string_len fields into SilcServer to
8188 include encoded ServerID for fast comparing without excess
8189 encoding of the ID's.
8191 * Cleaned up WHOIS command on server side. Added following static
8194 silc_server_command_whois_parse
8195 silc_server_command_whois_check
8196 silc_server_command_whois_send_reply
8197 silc_server_command_whois_from_client
8198 silc_server_command_whois_from_server
8200 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8201 arguments in command replies. All command functions should be
8202 updated to use this macro.
8204 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8206 * Minor typo fixes on command reply handling on server.
8208 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Added silc_server_command_add_to_channel internal routine to add
8211 the client to the channel after router has created the channel and
8212 sent command reply to the server.
8214 * Added generic silc_server_send_command to send any command from
8217 * Use static buffer with ID rendering instead of duplicating data.
8219 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * Fixed a channel user mode bug when joining to a channel server gave
8222 everybody channel founder rights, oops.
8224 * We mark ourselves as the router of the incoming server connection
8225 if we are router ourselves. This way we can check in some packet
8226 sending functions whether it is locally connected server. For
8227 incoming router connections we put NULL.
8229 * For router sending packets locally means now always sending the
8230 packet cell wide; to local clients and local servers. For normal
8231 server sending packet locally means sending it to only local
8234 * Fixed the JOIN command to really work in router environment. If the
8235 channel is created it is always created by the router. Router is
8236 also responsible of making the initial joining to the channel,
8237 sending JOIN notify to the sending server and distributing
8238 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8239 does not exist server doesn't do anything else but forward the
8240 command to the router which performs everything.
8242 * Added silc_server_send_channel_key function to send the Channel Key
8245 * Added silc_server_create_channel_key to create new channel key. The
8246 channel key is now re-generated everytime someone joins or leaves
8247 a channel, as protocol dictates. Note: channel->key_len is the
8250 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8252 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8253 packet_receive.[ch] to separate packet sending and receiving
8254 routines. The server.[ch] now includes everything else including
8255 actual packet processing (writing and reading data) and other
8258 Renamed silc_server_private_message_send_internal to
8259 silc_server_send_private_message. The routine is still though
8260 used only to relay private messages as server does not send
8261 private messages itself.
8263 Renamed silc_server_new_channel to silc_server_create_new_channel
8264 and added new function sicl_server_new_channel that handles the
8265 incoming New Channel packet. Added also new sending function
8266 silc_server_send_new_channel to send New Channel Payload.
8268 * Added new function silc_server_notify to process incoming notify
8269 packet to the server/router. Server may then relay the notify
8270 to clients if needed.
8272 * Added new function silc_server_new_channel_user to process incoming
8273 New Channel User packet. Router will redistribute the packet and
8274 send JOIN notify to its local clients and locally connected servers
8275 if needed. Normal server will send JOIN notify to its local client
8276 on same channel when received this packet. Added also corresponding
8277 sending function silc_server_send_new_channel_user to sent the
8280 * Added boolean route argument to send_notif_to_channel and
8281 packet_send_to_channel functions to attempt to route the packet
8282 if it is TRUE and send only locally if it is FALSE.
8284 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8286 * silc_server_replace_id now broadcasts the received replace ID
8287 packet if it is not broadcast packet already. The router must
8288 broadcast to inform other routers about changed ID.
8290 * Added backpointer to server's router into SilcServer context in
8291 silcd/server_internal.h.
8293 * Fixed silc_server_packet_broadcast to send correct broadcast
8296 * The channel key is now distributed to the local client as soon
8297 as it is received from the router (in router environment) so that
8298 no other packet may be sent for the channel until client has
8301 * silc_server_remove_channel_user now broadcasts the received
8302 Remove Channel User packet if it is not broadcast packet already.
8303 The router must broadcast to inform other routers about removed
8306 * Added users field into SilcPacketContext that is a reference count
8307 of the context. One can increase the reference count by calling
8308 silc_packet_context_dup which is now changed to just increase the
8309 reference count instead of duplicating the data. The reference
8310 count is decresed by calling silc_packet_context_free that will
8311 free the data after the reference count hits zero.
8313 For now on the packet context and everything allocated into it
8314 (including the raw packet from network) must be freed by calling
8315 the new silc_packet_context_free function. Added also new function
8316 silc_packet_context_alloc that must be used now to allocate the
8317 context. This also means that if a routine is asynchronous from
8318 silc_[client/server]_packet_parse_type the packet context must
8319 be duplicated by calling silc_packet_context_dup. Otherwise it
8320 gets free'd after silc_[client/server]_packet_parse_type returns.
8321 Also, one must remember that if packet is duplicated then its
8322 reference count must be decresed by calling the free function as
8323 many times as it was duplicated.
8325 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8326 from both client and server.
8328 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8330 * Made joining to a channel working in router environment.
8332 * Cleaned up JOIN command on server side and create function
8333 silc_server_command_join_channel internal routine to make the
8336 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8338 * Changed silc_command_pending list to SilcDList. Also, added
8339 `ident' field to SilcServerCommandPending structure to identify
8340 the reply and to call correct callback.
8342 Added silc_server_command_pending_check function to replace the
8343 corresnponding macro. The silc_command_pending list is not
8346 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8347 to set identifier to previously allocated Command Payload. It
8348 is used to set identifier for command when resending Command
8351 * Added silc_command_payload_encode_payload to encode Command
8352 Payload buffer from SilcCommandPayload structure.
8354 * Added silc_argument_payload_encode_payload to encode Argument
8355 payload buffer from SilcArgumentPayload structure.
8357 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8359 * Changed WHOIS command to support router connection on server side.
8360 The whois request is always sent to router unless the server is
8361 standalone server. After server has received the reply from the
8362 router will it send the reply to the client.
8364 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8365 broadcast received broadcast packet. The function is used only
8366 by router. The broadcast packet is always sent to the router's
8369 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8370 render given ID to printable string, for log files for example.
8372 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8374 * Made basic router to router connections working. At least they
8375 can now connect to each other but nothing really works the way
8376 they are supposed - yet.
8378 * Added new initiator token to RouterConnection configuration
8379 file in silcd/serverconfig.[ch]. It is used to tell whether we
8380 are the initiator to the remote router or whether we'll expect
8381 the other end to connect.
8383 * Moved registering of listener task to silc_server_init, hence
8384 the server starts listenning as soon as it is run, even if it
8385 does not have connections to other routers. Let's see how well
8388 * Changed default connection retry timeouts for more suitable in
8391 * Removed cipher and such arguments from silc_idlist_add_client
8392 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8393 Added new function silc_idlist_add_data to add the keys and stuff
8396 * Added SilcIDListData structure and added it to SilcClientEntry
8397 and SilcServerEntry as their first field in the structure. This
8398 way we can explicitly cast the ID entries to the SilcIDListData
8399 structure and get common data for the entries. In past, we had
8400 to first check what type of connection it is and then cast it to
8401 correct ID entry type. Now, we can directly cast the opaque
8402 pointer to the SilcIDListData (no matter what ID entry it actually
8403 is) and get the data needed.
8405 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8407 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8408 in some circumstances even if threre were timeout tasks, though not
8409 IO tasks, but tasks anyway. Now fixed.
8411 * Defined SilcServerConnection structure to hold connection specific
8412 stuff about directly connected servers and routers. The definition
8413 is currently in silcd/server_internal.h. I thought about having
8414 a bit more important role fro this struct but for now it is used
8415 only when connecting to other server (or router actually).
8417 * Added connecting retry support in server when connecting to
8418 router(s). The retry feature implement exponential backoff
8419 algorithm. Also, added SilcServerParams structure to hold default
8420 parameters for server. For now, it include these retry settings
8421 and are hard coded. After server is moded to be as Silc Server
8422 Library this structure will be more important.
8424 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8426 * Changed client librarys channel->clients table to SilcList and
8427 changed code accordingly.
8429 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8431 * Changed client's channel table to SilcList and changed code
8432 accordingly. Also changed SilcChannelClientEntry to include back-
8433 pointer to the channel so that client entry can use that structure
8434 as list as well and we have fast cross-reference to the channel.
8435 This change dramatically decreased the complexity of channel
8436 handling with client entry and vice versa (removed one extra
8437 loop when searching for channel entry from many functions).
8439 * Changed server->sim from table to SilcDList and changed code
8442 * NAMES command can now be used from user interface. It will show
8443 the user list on the channel, neatly.
8445 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8446 Code now saves realname of the user if it becomes available.
8448 * Renamed configure.in to configure.in.pre and made ./prepare
8449 script to automatically add correct version string to
8450 configure.in which it creates from configure.in.pre.
8452 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * NAMES command reply now shows users mode with the nickname when
8457 * Moved silc_client_ch[u]mode[_char] functions from
8458 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8459 place sucks, they are utility functions and should be in some
8462 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8464 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8467 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8471 * Added TRQ (efficient deque and list library) into lib/trq. This is
8472 a very good list library that is currently used in the SILC. Defined
8473 SilcList API over the library because I didn't like the API very
8474 much. See lib/trq/silclist.h for the API and examples of how to
8475 use the API. Fixed various places in the code to use the new
8476 SilcList API. The SilcList is meant for lists that has a structure
8477 already defined as a list. It is not suitable to add just some
8478 context to the list (in TRQ, the context is the list actually).
8480 So, I defined SilcDList that can be used for the purpose where
8481 predefined list structure does not exit. This can be used as
8482 such list. Now some context just can be added to the SilcDList.
8483 Currently this list is not used in the SILC just yet, though there
8484 are a lot places where this can replace dynamically allocated
8485 tables and I will fix these places, later, to use SilcDList.
8486 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8487 and use TRQ internally).
8489 Also fixed some annoying warning messages that the original TRQ
8490 code generated. Also minor changes to TRQ's Makefile.in.
8492 * Added support for querying by Client ID to both WHOIS and
8493 IDENTIFY commands into server, as required by the protocol.
8495 * Removed method function pointers from SilcBuffer structure. They
8496 weren't used to anything and just increased the context size for
8497 no good reason. This change also made silc_buffer_alloc and
8498 silc_buffer_free functions inline functions.
8500 * Disabled command flooding detection support until it's fixed so
8501 that it accepts commands in but does not execute them more than once
8504 * Added silc_net_localhost(), to return local hostname, into
8505 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8506 that must be initialized before calling silc_client_init.
8508 * Added new function: silc_server_send_notify_on_channels to send
8509 notify messages to all channels client has joined. It is assured
8510 that the message is sent only once per client.
8512 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8513 lib/silcutil/silcutil.[ch] as silc_format function. The new
8514 function is generic and is used by server as well, not only by
8515 the logging routines.
8517 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8518 the provided version string was not acceptable. Added new function:
8519 silc_ske_check_version into lib/silcske/silcske.h. The function
8520 must be implemented by the application (client or server) and it
8521 does not reside in the SKE library. The function checks the version
8522 string remote end sent.
8524 * Added back pointers (to opaque context and to SilcSocketConnection)
8525 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8527 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8528 duplicate packet context structure.
8530 * Changed `notify' client operation to send same arguments as client
8531 receives from server except for ID's. ID's are mapped to correct
8532 ID entry and that is returned. Also, if channel entry is not sent
8533 by server but the notify is for channel the channel entry is sent
8534 to application (otherwise application doesn't know that it is for
8535 channel (library gets it from packet's Destination ID)).
8537 * Added silc_client_remove_from_channels into client library to
8538 remove a client from all channels it has joined to. Used when
8539 received SIGNOFF notify from server. Added also new function
8540 silc_client_replace_from_channels to replace old ID entry with
8541 new ID entry on all channels. Used when received NICK_CHANGE
8544 * Fixed ID Cache list handling in silc_idlist_get_client in
8545 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8546 to get (or query) client by ID.
8548 * Updated TODO list.
8550 * Added connection authentication status message defined by the
8551 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8552 support for these into the code in client and server side.
8554 * Added generic function silc_client_send_command to send any command
8555 with variable argument list. Application should use this function
8556 to send commands if the command functions provided by the library
8557 does not suite for the application's user interface needs.
8559 * Added new `failure' client operation. Application is notified about
8560 received failure packet if client is executing a protocol. In this
8561 case the protocol's execution has failed.
8563 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8564 is required by the protocol.
8566 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8567 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8570 * Added status flag to SilcSKE object to indicate realtime status
8571 of the SKE protocol.
8573 * Application receives now exactly same command reply arguments as
8574 the library receives from server. However, if ID is received the
8575 corresponding ID entry is returned to the application (eg. Client
8576 ID is mapped to correct SilcClientEntry entry and that is returned).
8577 Changed command_reply client operation due to this change.
8579 * Changed all ID's in commands and in command replys as ID Payloads.
8580 Change affected both client and server side codes.
8582 All ID's sent in SILC network (with execption of ID's in SILC
8583 Packet header) are sent in ID Payload to support variable length
8586 * Server now notifies nick changes and notifies all clients on
8587 the channels about the new nickname (about the new Client ID,
8590 * Implemented CMODE command to change channel modes. Supports all
8591 channel modes defined by the protocol specs except ban and invite
8592 lists. (Also, private channel key mode is supported but support for
8593 setting private channel key in client is missing, thus, this mode
8594 has no effect on client side (except that server requires that the
8595 client uses private channel key and normal channel traffic does not
8598 Also, invite mode works per se, but INVITE command does not work
8599 yet correctly, so you can set channel as invite only channel but
8600 inviting clients to the channel does not work (it is yet to be
8601 thought what's the best way to do it).
8603 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8604 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8605 Implemented CUMODE command to change user's mode on the channel.
8606 Supports all modes defined by the protocol specs.
8608 * Added NAMES command reply to return users modes on the channel.
8610 * Removed unnecessary and slow ciphers from lib/silccrypt.
8612 * Set SO_KEEPALIVE option to connection sockets by default.
8614 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8616 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8617 redefined the Notify Payload into protocol specs.
8619 * Added silc_id_payload_parse_id to get ID directly from raw
8622 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8624 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8625 accept searching by Client ID as well.
8627 * Added support for LEAVE and SIGNOFF notify types in client library.
8629 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8630 to parse ID Payload from raw data.
8632 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8634 * Added flags parameter into silc_ske_assemble_security_properties
8635 function in lib/silcske/silcske.[ch].
8637 * Changed notify client operation to fit better for notify messages
8638 sent by server. The notify payload received from server is now
8639 passed to the application (after parsing it to SilcNotifyPayload).
8640 It is application's responsibility to retrieve the arguments
8641 from the payload and show the message the way it wants. The message
8642 sent by server is implementation specific.
8644 * Changed public keys to comply with the protocol specification.
8645 Old public keys are not supported anymore and are not compatible.
8647 * Removed nickname from Channel Payload as the latest draft removed
8648 it. The client must resolve the nickname from the NAMES command
8649 reply received when it joined the channel.
8651 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8653 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8655 * Fixed some errors in protocol specification drafts.
8657 * Created lib/silccore/silcnotify.c to implement Notify Payload
8658 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8659 generic payloads described by protocol specifications. The file
8660 includes implementations for ID Payload and Argument Payload.
8662 * Changed Command Payload implementation to use the new Argument
8663 Payload. Changed command_xxxx_payload to command_payload_xxxx
8664 to comply with SILC coding conventions.
8666 * Added suppport for Argument Payload handling in Notify Payload
8667 implementation as protocol requires it. Added the new support
8668 into server and client lib as well.
8670 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8672 * Added support for multiple nicknames on same channel. [n] is
8673 added locally to the nickname if there are more than one same
8674 nicknames on the channel.
8676 * Server now sends all nicknames that matched WHOIS request.
8677 Client also shows the list received from server.
8679 * Added TOPIC command to client side. User can now set and show
8680 current topic on channel.
8682 * Added MOTD command to client and server. Also, server sends the
8683 motd when client connects to the server.
8685 * Changed version strings to comply ISO 8601.
8687 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8689 * Fixed protocol error handling in client library. It should now
8690 cope even if the SKE fails for some reason.
8692 * Made new protocol specification drafts for submitting to IETF.
8694 * Implemented TOPIC command to server in silcd/command.c.
8696 * Added two new notify types into lib/silccore/silcnotify.h:
8697 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8698 notify nickname change and topic setting/change on a channel.
8700 * API change of command_reply operation in client library. The
8701 application gets now the status type received from server as well.
8703 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8705 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8707 * Cras fixed and optimized the packet handling even further and
8708 it should work now. Minor change to the prototype of function
8709 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8711 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8713 * Added new function into lib/silcutil/silcschedule.[ch]:
8714 silc_schedule_with_fd to select() a specified fd. The function
8715 returns after timeout expires or data arrives or goes. The
8716 function is used by packet routines to wait that all data is
8717 received from network.
8719 * Fixed data reading from network in lib/silccore/silcpacket.c.
8720 The code now assures that all data is read from the fd and then
8721 continues packet processing. This was a bug fix since the code
8722 used to drop some data in some circumstances.
8724 * Added new function into lib/silcclient/client.[ch]:
8725 silc_client_start_key_exchange to start key exchange after
8726 connection has been established to server. The code internally
8727 now uses this funtion but its main purpose was to provide it
8728 for applications that perform their own connecting. After
8729 application has created a connection it merely calls this
8730 function to start the key exchange between client and server.
8731 The library takes care of everything else after that.
8733 Updated also lib/silcclient/README to explain the usage of
8736 * Do not send to application information that connection has
8737 been established. Application gets notified it by connect
8740 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8742 * Applied cras's patch to add silc_schedule_one function. The
8743 function runs scheduler once and returns.
8745 * Fixed the scheduler after cras messed it up. The timeout
8746 handling works now as it's supposed to work.
8748 * Added into lib/silccore/ silcnotify.h to include notify
8749 message types support. Changed silc_server_send_notify*
8750 functions, in server.[ch], to support those new notify types.
8751 Added the support for the notify types into client library,
8752 as well. Added new notify client operation into ops.h in
8755 * Changed silc_server_packet_send_to_channel to send normal
8756 packets instead of just channel message packets. The function
8757 is now used to send the notify packets to channels. It is not
8758 used to send channel message packets anymore, as server never
8761 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8762 va_arg()s as it seems to require it nowadays. I guess, if SILC
8763 is compiled with older va_arg() the new code should work anyway.
8765 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8767 * Splitted core library. Core library (lib/silccore) includes
8768 now only SILC protocol specific core (and common) components.
8769 Created new utility library (lib/silcutil) that includes more
8770 generic purpose stuff. The stuff for util library was taken
8771 from the old core library. This was minor and easy split.
8773 * Created SILC Client Library (lib/silcclient) that includes
8774 implementation of the SILC client without user interface. This
8775 was major move from silc/ directory. The code has been changed
8776 so that it is transparent towards the user interface. The
8777 silc/ directory includes now the same user interface as before
8778 and it uses the new client library. Read lib/silcclient/README.
8779 Basicly, the client library performs everything else related
8780 to SILC except user interface handling. Also, configuration
8781 files are considered to be part of user interface and library
8782 does not handle them.
8784 This change also changed a lot of structures, function naming etc.
8785 Most important change was that SilcClientWindow object was
8786 renamed to SilcClientConnection in the client library. Created
8787 also new file lib/silcclient/ops.h. Also added new files
8788 silc/local_command.[ch] and silc/client_ops.[ch].
8790 All these changes were made to make it easier for user interface
8791 designers to create what ever user interface for the SILC client
8794 It is also expected that the server will be moved to lib
8795 directory as well and SILC Server Library will be created;
8796 sometimes in the future.
8798 * Removed Local commands from lib/silccore/silccommand.h as
8799 they are application specific and new client library does not
8800 handle any of those anymore.
8802 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8803 old client implementation in silc/.
8805 * Added support for callback functions in SILC_LOG_* macros.
8806 Application can now set its own callbacks that will be called
8807 instead of using the default functions that will always print
8808 the debug messages to stderr (or stdout). Also, debugging can
8809 now be disabled by setting silc_debug to FALSE and re-enabled by
8810 setting it to TRUE. Note, that logging will still work even
8811 if debugging is disabled.
8813 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8814 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8815 silc_log_reset_debug_callbacks.
8817 * To enable debugging in silc client one must give now -d
8818 option on command line.
8820 * Changed silc_schedule_init to automatically allocate task queues
8821 if they are not allocated before calling it.
8823 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8825 * Added GMP 3.1 into math library.
8827 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8829 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8830 a channel in SILC network. The packet is used by servers and
8831 routers to notify other routers that user has left a channel.
8832 This little feature was missing until now. Added the feature
8833 to protocol specification as well.
8835 Added functions: silc_server_send_remove_channel_user and
8836 silc_server_remove_channel_user into server.[ch].
8838 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8839 lib/silccore/silcpacket.h. However, they are not implemented
8842 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8844 * Fixed joining to a channel and sending channel messages
8845 between server and router. The channel message sending should
8846 now work inside a cell.
8848 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8850 * Fixed the private message sending between server and router.
8851 The private message sending should now work inside a cell.
8853 * Added silc_server_replace_id into server.[ch] to replace
8854 existing ID in the SILC network.
8856 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8857 and silc_idlist_replace_server_id into idlist.[ch] in server.
8859 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8861 * Fixed the server to server connections. Server can again now
8862 connect to router. Router to router connections probably does
8865 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8867 * Added dynamic protocol registering support. Now protocols can
8868 registered and unregistered on the fly. Patch by cras.
8870 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8872 * Added lib/contrib directory to hold routines that some platforms
8873 don't have but are needed by SILC.
8875 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8876 into lin/contrib to provide getopt() and getopt_long() for
8877 those who don't have it.
8879 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8881 * Added AWAY command to client. When away message is set and
8882 client receives a private message packet the client automatically
8883 replies to the sender with the away message.
8885 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8886 bug seemed to be the cause of recent problems when compiling
8889 * Added version detection support to SKE protocol specification
8890 and added the new changes to the SKE implementation as well.
8891 There were other minor changes in the SKE protocol as well.
8893 Many changes in lib/silcske/silcske.[ch] and in
8894 lib/silcske/payload.[ch].
8896 * Added ^U functionality, clear input line. Patch from cras.
8898 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8900 * Mainly small bugfixes on core library. Fixed some debugging
8901 logging and buffer overflow in silclog.c.
8903 * Updated config.sub and config.guess on the distribution tree.
8905 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8907 * Added command lagging support in server. Client may execute
8908 commands now only once in two seconds.
8910 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8912 * Optimized packet reception. MAC computation and checking is now
8913 also more optimized. A lot previously duplicated code is now
8914 used as generic by both client and server.
8916 * Fixed key pair generation in clientutil.c
8918 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8920 * Added into lib/silccore/silcbufutil.[ch] new function;
8921 silc_buffer_realloc.
8923 * Moved generic packet sending/encryption functions to
8924 lib/silccore/silcpacket.[ch] from client and server. Some
8925 rewriting of the functions.
8927 * Moved all generic packet reception/decryption functions to
8928 lib/silccore/silcpacket.[ch] from client and server. The
8929 packet processing is now much cleaner in both client and server.
8930 These were major changes in both client and server.
8932 * Created many common functions in server to do packet sending.
8933 Previously code were duplicated a lot, this has been removed
8936 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8938 * Rewrote major parts of the ID cache system. Don't know
8939 whether it is better now or not but at least the API is more
8942 * Major rewrite on ID cache stuff on client because of the ID
8943 cache API changes. Added idlist.c to client.
8945 * Also major rewrite on ID cache stuff on server as well.
8946 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8947 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8948 in hand, instead they are all put into the ID cache system now.
8949 All server_idlist_* routines uses ID cache now instead of
8950 traversing its own lists (those lists does not exist anymore).
8951 SilcIDList though still exists. Also, SilcXXXEntry's are
8954 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8956 * Finally made the SKE implementation compliant to the protocol
8957 specification. All mp integers are now binary encoded as
8958 opposed being HEX encoded.
8960 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8963 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8964 functions: silc_[encode/decode]_pem. Also added function
8965 silc_encode_pem_file to PEM encode with newlines ('\n') for
8968 * SILC public keys are now encoded either PEM or binary. Same
8969 option is for private keys as well. By default private keys
8970 are binary encoded and public keys PEM encoded. Silly HEX
8971 encoding were removed.
8973 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8974 function to create fingerprints.
8976 * Fixed a bug in SHA1; does not change the original data anymore.
8978 * Partly implemented INFO command on client and server side.
8979 Fixed CLEAR command. Changes to SERVER command; show current
8980 server(s) when giving command without arguments. Added
8981 VERSION command to client.
8983 * Added check to server that unregistered connections cannot
8984 execute commands (unless it is specificly allowed).
8986 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8988 * Fixed screen refresh.
8990 * Fixed channel joining bug from client. On some circumstances
8991 client tried to join to a channel it had already joined.
8993 * Added public key verification process into client's protocol.c.
8994 The client now verifies the public key from user and saves
8995 it into ~./silc/serverkeys/ directory.
8997 Added into: clientutil.[ch]: silc_client_verify_server_key.
8999 * Changed SKE protocol's silc_ske_initiator_finish function
9000 to accept callback function that verifies the received public
9001 key. Removed old silc_ske_verify_public_key function.
9003 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9005 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9006 silc_pkcs_private_key[_data]_set.
9008 * Made the password and public authentication more cleaner in
9009 server's protocol.c.
9011 * Removed historic and obsolete protocol `channel_auth' from
9012 both client and server.
9014 * Removed wrong way of sending command status messages from
9015 server to client in server's command.c. The old way violated
9016 protocol specification.
9018 Changes to silccore/silccommand.[ch]: removed
9019 silc_command_encode_status_payload -> not needed anymore,
9020 changed silc_command_encode_payload_va to accept extra
9021 argument on variable argument list. The argument type must
9022 now be provided to the function. Also, added new function:
9023 silc_command_encode_reply_payload_va which is same as
9024 normal command_encode_payload_va except command status type
9025 is provided as extra argument.
9027 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9029 * Added ~./silc directory handling. The directory includes the
9030 public and private keys for the client.
9032 Added silc_client_check_silc_dir, silc_client_create_identifier
9033 and silc_client_load_keys.
9035 * Implemented SILC protocol compliant public key. Added public
9036 and private key saving to and loading from files.
9038 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
