1 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the silc_get_time to accept time value as argument
4 or if zero is sent return current local time. Affected
5 file lib/silcutil/silcutil.[ch].
7 * Added STATS command to client library and Irssi SILC client.
8 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
10 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
12 * Assure that channel key is set before sending it. May
13 crash server otherwise. Affected file silcd/packet_send.c.
15 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
17 * Assure that endless loop cannot happen with detached client
18 resolving on normal server. Added idlist status
19 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
20 silcd/idlist.h and silcd/packet_receive.c.
22 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
24 * Incoming file transfer request cannot use same session as
25 the sending session. This can happen when sending file to
26 yourself. Crashed the client on quit. Affected file
27 lib/silcclient/client_ftp.c. Bug #24.
29 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Implemented the draft-riikonen-precense-attrs draft and
32 the Attribute Payload into the lib/silccore/silcattrs.[ch].
34 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
36 * Distribute the SERVER_SIGNOFF notify also to local backup
37 routers from the primary router. The backup router may not
38 have the signing of local server directly connected and need
39 to know about the signoff. Affected file silcd/server_util.c.
41 * Use the primary router as the origin of the locally connected
42 server when it is disconnecting from the backup router since
43 that's where it really is coming from. Now the clients from
44 the disconnecting server are removed correctly and "shadow"
45 clients are not left to the backup router. Affected file
48 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
50 * If normal server is standalone and found existing but disabled
51 channel, do not re-create the channel since it creates
52 duplicate same channels. Affected file silcd/server.c.
54 * Added anonymous client connections support to server. New
55 "anonymous" configuration option to ConnectionParams section
56 added. If set to true, the username and hostname information
57 of the client will be scrambled and anonymous user mode is
58 set automatically to the user. Affected files are
59 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
61 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
63 * In JOIN notify handling, mark that the cache entry of the
64 client cannot be expired. Can cause crashes on normal
65 server (asserts client->channels). Affected file is
66 silcd/packet_receive.c.
68 * From now on distribution versions are used as protocol versions
69 instead of by default using the Toolkit base version as protocol
70 version. Affected file prepare.
72 * Do not set the locally resolved hostname for local client
73 entry but take what server sends. This way the real hostname
74 is showed in WHOIS for yourself. Affected file is
75 lib/silcclient/idlist.c and lib/silcclient/client.c.
77 * Resolve local info with IDENTIFY when connecting to server.y
79 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
81 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
82 for implied search (not needed on platforms which has native
83 pthreads library). Use --without-pthreads to disable threads.
84 Affected file is configure.in.pre
86 * Fixed --with-iconv on platforms which need to bypass (broken)
87 native iconv(). Affected file is configure.in.pre
89 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
91 * Moved -C option parsing in Irssi SILC client at same time
92 as other options. The UI was initialized earlier and caused
93 problems on command line. Bug #16. Affected file is
94 irssi/src/silc/core/silc-core.c.
96 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
98 * Added global variable silc_log_timestamp that tells silclog
99 wether to print or not the timestamp in the logging files.
100 Affected file lib/silcutil/silclog.[ch].
102 * Added silcd configuration option Timestamp in the Logging
103 section. Affected file silcd/serverconfig.[ch],
104 doc/example_silcd.conf.in.
106 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
108 * Fixed fingerprint checking to check for entirely empty
109 fingerprint instead of two first bytes when determining
110 if it is set. Bug #18. Affected file silcd/command.c.
112 * Fixed duplicate PKCS name registering to not allow it.
113 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
115 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
117 * Conditionalize non-gcc compiler optimizations for various
118 platforms, enable those commented out. Cleanups.
119 Affected file lib/silcmath/mpi/configure.in
121 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
123 * silc_rng_exec_command() left zombie processes if command
124 didn't generate any output. Affected file
125 lib/silccrypt/silcrng.c
127 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
129 * Rewrote iconv checking, introduce --with-iconv for systems
130 which rely on libiconv. Check if iconv() provided by libc
131 is good enough, otherwise demand libiconv. Affected file
134 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
136 * Search for ldopen() also in libc. This enables SIM support
137 on *BSD systems. Based on patch from Alex Zepeda. Affected
138 file configure.in.pre
140 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
142 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
143 This fixes prepare on *BSD systems. Affected file
146 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
148 * More fixed for not having purge timeout for global clients
149 that are on channel. Affected files silcd/command_reply.c
152 * Fixed the rekey protocol to work with backup router connections.
153 Rekey packets are now allowed on disabled connections as
154 well. Affected files silcd/packet_send.c and server.c.
156 * Do not switch to be as backup router when shutting down and
157 closing the primary connection. Affected file silcd/server.c.
159 * Fixed memory leaks in backup router deleting. Added
160 silc_server_backup_free to free all data during shutdown of
161 server. Affected files silcd/server_backup.[ch].
163 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
165 * Do not process commands if the sock->user_data is NULL.
166 Affected file silcd/command.c.
168 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
170 * Fixed buffer overflow and security problems (loosing bits
171 in CFB encryption) in SILC RNG. Problems reported by
172 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
174 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
176 * Added yet more checks that client is not expired on global
177 list if it is on channels. Affected file is
178 silcd/command_reply.c.
180 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
182 * Merged c0ffee's MIME signal patch which adds support for
183 sending also MIME messages in Irssi SILC Client, and handling
184 received MIME messages in a signal (and perhaps doing something
185 to non-textual MIME messages).
187 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
189 * Fixed pending command deletion in server and client library
190 to check the whole list instead of breaking after first found.
191 The affected files are silcd/command.[ch] and
192 lib/silcclient/command.[ch].
194 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
196 * Return NO_SUCH_CHANNEL error in USERS for channel that is
197 secret or private, otherwise it's possible to find out
198 whether a secret channel exists or not. Affected file
201 * If CMODE change fails during the mode setting, assure that
202 the old mode mask is set for the channel back. Affected
203 file silcd/command.c.
205 * Fixed passphrase saving on +a channel on normal server
206 after successful JOIN command. Affected file silcd/command.c.
208 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
210 * Remove server/router operator privileges in DETACH command,
211 since it's possible to resume to server where these
212 privileges would not be allowed for the client. Affected
213 file silcd/command.c.
215 * Do not set to wait for backup in rehash of the server.
216 Affected file silcd/server.c.
218 * Do not check listener sockets when counting how many
219 socket connections we have. Affected file is
222 * Do not announce disconnected clients that are remaining
223 in history (for WHOWAS). This is because SIGNOFF notify
224 for these has been sent earlier already. Affected file
227 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
229 * Buffer overflow with CUMODE command's mode->mode character
230 conversion. Reported by Ville Räsänen. Affected file
231 lib/silcutil/silcutil.c.
233 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
235 * Allow heartbeat packets to go disabled connections anyway.
236 Affected files silcd/server.c and silcd/packet_send.c.
238 * Do not broadcast New Channel packets with List flag set
239 in the packet to backup routers. The router must check
240 for the correctness of the packets before sending them.
241 It is possible that router will have enforce Channel ID
242 change and this would cause desync in the backup router.
243 Affected file silcd/packet_receive.c.
245 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
246 are handled in list parsing. They are not list packets
247 anymore. Affected file silcd/packet_receive.c.
249 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Stop waiting for backup router through the timeout, not
252 directly after backup router has arrived. Affected file
255 * Do not re-create channel keys and send them when removing
256 clients in server shutdown. Affected files are
257 silcd/server_internal.h and silcd/server_util.c.
259 * Notify distribution to backup routers was missing from
260 the silc_server_send_notify_dest function which caused
261 desyncing problems with backup router. Affected file is
264 * The client's channel removing was working wrong on
265 backup router. It assumed that it doesn't know global
266 information but backup router does know. For this reason
267 it could remove channel when it wasn't supposed to do that.
268 Affected file silcd/server.c and silcd/server_util.c.
270 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Stop for a couple seconds after badkup router has become
273 primary router. Affected file silcd/server.c.
275 * Added silc_server_remove_servers_by_server, which is used
276 to remove servers originated from some other server. Also
277 clients of those servers can be removed too. Affected file
278 silcd/server_util.[ch].
280 * When removing clients after a server has signed of remove
281 also all servers behind that server (unless they are known
282 to be available locally), and send SERVER_SIGNOFF for each
283 of the server separately. Also the signed off clients are
284 sent now separately per signed off server. The affected files
285 are silcd/server.c and silcd/server_util.[ch].
287 * All servers added with silc_idlist_add_server must always
288 have both "router" and "connection" pointers set. Otherwise,
289 bad server entries may be left around in the cache.
290 Affected file silcd/command_reply.c.
292 * Do not create the channel key in NEW_CHANNEL packet
293 processing if the channel is empty. Affected file
294 silcd/packet_receive.c.
296 * Completed backup router support for standalone routers.
297 Supports also servers in the cell that do not use the backup
300 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
302 * Fixed a bug in silc_string_regexify which did not add '^'
303 at the start of each string, and thus the matching was
304 not explicit. For example ban list iikone@*!*@* would
305 match also "priikone", which is wrong, it would have to be
306 *iikone@*!*@* to match also "priikone". Affected
307 file lib/silcutil/unix/silcunixutil.c.
309 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
311 * Enable all local server connections before updating client
312 caches when we've become backup router. Otherwise, signoff
313 packets may not reach the clients. Affected files are
314 silcd/server.c and silcd/server_util.[ch].
316 * Fixed a bug in version string parsing which could crash
317 the program with specially formatted version string.
318 Bug reported and patch provided by Ville Räsänen. Affected
319 file lib/silcutil/silcutil.c.
321 * Handle the disconnection immediately when DISCONNECT
322 packet is received in server. Affected file silcd/server.c.
324 * Primary router now waits a short time (10 seconds) for
325 backup router connection before accepting any other
326 connection (except local). Affected file silcd/server.c,
329 * Fixed a crash in client libary in NICK_CHANGE notify when
330 NICK_CHANGE arrived for client entry we are resolving
331 currently. Affected file lib/silcclient/client_notify.c.
333 * Call the sconn->callback completion even if error had
334 occurred. Start reconnecting always if connection to
335 primary router fails during backup router protocol.
336 Affected files silcd/server.c and server_backup.c.
338 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
340 * Added functions silc_server_send_opers and
341 silc_server_send_opers_notify to send packets stricly
342 to operators. Added macro SILC_SERVER_SEND_OPERS macro
343 to send variable argument notify to operators.
344 Affected files silcd/packet_send.[ch] and silcd/server.h.
346 * Removed UMODE rights checking with UMODE_CHANGE notify.
347 Affected file silcd/packet_receive.c.
349 * Server/router operator now receives notify when network
350 switches to backup router and when it resumes the use of
351 primary router. Affected file silcd/server.c and
352 silcd/server_backup.c.
354 * Fixed the updating of client information after backup
355 resuming protocol is over; update all except local clients
356 to the new primary router. The affected file is
359 * Added support for closing active connections in rehash
360 that were unconfigured by the user. Supports currently
361 closing server and router connections. Affected file
364 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
366 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
368 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
369 is NULL since seems that on some platforms NULL is allowed
370 and on some it's not. Fallback encoding is used instead.
371 Affected file lib/silcutil/silcstrutil.c.
373 * Fixed statistics updating for incoming server connection
374 which could cause problems when re-connecting. Affected
377 * Preliminary backup router support for standalone router
378 added. Affected files in silcd/.
380 * Mark server connections in backup router disabled before
381 and after backup protocol. Affected file is
382 silcd/server_backup.c.
384 * Added support for reconnecting to remote server connection
385 even if the protocol fails, and if the configuration wants
386 us to keep trying to connect anyway.
388 Server connection is not allowed to backup router if
389 backup router does not have connection to primary router yet.
391 Affected file is silcd/server.c.
393 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
395 * Added silc_client_udpate_server function to update changed
396 server info. Affected file lib/silcclient/idlist.[ch].
398 * Added check for server entries that are being resolved when
399 notify is received. If being resolved, handle the received
400 notify only after it's resolved so that all notifys are
401 handled in same order as received from the server.
403 Added similar resolver check to channel entries. Every
404 notify that cause resolving of any information that affects
405 channel entry marks the channel entry in waiting state.
406 After whatever resolving is over the waiters are signalled
407 and only then the notifys are handled in the same order
408 as delivered from the server.
410 Affected files are lib/silcclient/idlist.[ch], and
413 * Fixed KILLED notify handling in normal server. Affected
414 file silcd/packet_receive.c.
416 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
417 is locally connected, or was locally connected (but may
418 be detached and connection is not active). Added also
419 SILC_IS_LOCAL for checking this status. Affected files
420 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
421 silcd/server.c and silcd/server_internal.h.
423 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
425 * Don't send or handle TOPIC_SET if topic is already set and
426 is same as being set. Affected files silcd/command.c and
427 silcd/packet_receive.c.
429 * Fixed CMODE change rights checking to work correctly when
430 removing modes by operator. Affected file is
433 * Fixed some handling with New Channel packet in router and
434 fixed some CMODE_CHANGE notify handling in server and router.
435 Affected file is silcd/packet_receive.c.
437 * Changed "disconnect" client operation to include the
438 reason of the disconnection and optional disconnection
439 message. Affected file lib/silcclient/silcclient.h.
441 * Made the compilation of lib/contrib/ stuff conditional.
442 Affected files configure.in.pre, lib/contrib/Makefile.am.
444 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
446 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
447 to the sender of the notify too, to avoid situation where two
448 notifys are in the network at the same time going to oppsite
449 directions. Affected file silcd/packet_receice.c.
451 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
453 * Delete the client from channel even if the cilent->id is
454 NULL. It was possible that client was deleted without
455 removing from channels (theoretically at least). Affected
456 file silcd/server.c and silcd/server_util.c.
458 * Free the client data too when resuming is not successful.
459 Affected file silcd/packet_receive.c.
461 * Merged some code from c0ffee's silc-plugin. Affected files
462 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
464 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
465 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
466 to the primary router connection, the other one returns
467 TRUE if packet must be broadcasted to network.
469 * All notifys that are destined to primary router (to network)
470 are now automatically sent to backup routers even if the
471 router is standalone (and has backup router). Affected files
474 * Added --without-irssi and --without-silcd configuration
475 options for disabling the compilation of these applications.
476 Affected file configure.in.pre and prepare.
478 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
480 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
481 UTF-8 encoding and decoding. Added also new encodings
482 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
484 Added also SILC_STRING_LANGUAGE which is language and charset
485 specific encoder and decoer for those platforms that support
486 iconv(). It can convert the UTF-8 to and from the locale
487 specific character set.
489 Affected file lib/silcutil/silcstrutil.[ch].
491 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
493 * Added function silc_get_command_name to the file
494 lib/silcutil/silcutil.[ch].
496 * Improved the server debug output a bit. Affected files are
499 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
501 * Save the channel passphrase when received succesful JOIN
502 command reply from router, on normal server. Otherwise
503 joinig +a channels from normal server is not possible.
504 Affected file silcd/command.c.
506 * Fixed a bug in TOPIC_SET notify handling. The notifier
507 may be other than client too, like server or channel.
508 It expected it to always be only client and ignored the
509 notify. Affected file silcd/packet_recieve.c.
511 * Removed some (unnecessary) debug printing from
512 lib/silccore/silcid.c and lib/silccore/silcargument.c.
514 * Do not force CMODE_CHANGE when server is announcing new
517 Router announces stuff only after server reannounces channel
518 after CHANNEL_CHANGE notify.
520 These fixes optimizes the announcing procedure, and perhaps
521 fixes some problems too. Affected file silcd/packet_receive.c.
523 * Fixed SERVER_SIGNOFF sending to local clients. It was
524 totally broken and sent the notify to all local clients,
525 instead of only to those that was on same channel as the
526 signing off clients. Affected file silcd/server_util.c.
528 * Added -D option to server. It can be used to give debug
529 level. The levels are from 0 - 99, and are predefined for
530 smooth server debugging. (see silcd.c for the predefined
531 levels). Affected file silcd/server.c.
533 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
535 * Fixed a bug in Irssi SILC client to close the connection
536 properly when disconnecting from server. Affected file
537 irssi/src/silc/core/client_ops.c.
539 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
541 * When authenticating as founder during JOIN command, check
542 that the one authenticating becomes the only founder on the
543 channel. Affected file silcd/command.c.
545 * Better checking for founder mode setting when CUMODE_CHANGE
546 notify is received. Affected file silcd/packet_receive.c.
548 * Close all connections when shutting down the server by sending
549 DISCONNECT packet. Close all listeners too when shutting
550 down the server. Affected file silcd/server.c.
552 * Handle DISCONNECT packet correctly in client library by
553 calling the "disconnect" client operation. Affected file
554 lib/silcclient/client.c.
556 * Handle local errors correctly during resuming. Affected
557 file lib/silcclient/client.c.
559 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
561 * The log file is not dupped internally anymore in
562 lib/silcutil/silclog.c. Fixed memory leaks too.
564 * The scheduler now dispatches all pending timeout tasks
565 when it is uninitialized with silc_schedule_uninit.
566 Affected file lib/silcutil/silcschedule.c.
568 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Added --enable-stack-trace option to configure. Added
571 memory allocation stack trace support. Added files

1094 and resume to the old client session. Added DETACHED user
1095 mode that server will set for detached client. Added new
1096 packet RESUME_CLIENT which is used to perform the resuming
1097 process. Added DETACH command. Updated the protocol specs,
1098 core library, client and server. Protocol TODO #22. Very
1099 many affected files around the tree.
1101 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1103 * Changed the CMODE's mode mask argument to be optional. If
1104 not provided then the command merely returns the current mode
1105 mask to the client. Updated protocol specs and the server.
1106 Affected file is silcd/command.c.
1108 * Changed the Killer's Client ID in KILLED notify to be just
1109 any ID payload since router server is allowed to kill as well.
1110 Updated protocol specs, client libary and server. Affected
1111 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
1112 and irssi/src/silc/core/client_ops.c.
1114 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1116 * Added new user modes ANONYMOUS for special anonymous servers
1117 that may set the mode for client, and BLOCK_PRIVMSG which
1118 client may set to block incoming private messages unless the
1119 Private Message Key flag is set (using private keys to protect
1120 private messages). Updated protocol specs and code in client
1121 and server and core library. Protocol TODO #23. Affected
1122 files are lib/silccore/silcmode.h, silcd/server.[ch],
1123 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
1124 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
1126 * Added new channel user mode BLOCK_MESSAGES which the client
1127 may set to itself to tell server not send channel messages.
1128 Other packets such as channel key packets are still sent.
1129 Protocol TODO #23. Updated the protocol specs, client and
1130 server. Affected files are lib/silccore/silcmode.h,
1131 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
1132 lib/silcutil/silcutil.c, silcd/command.c, and
1133 silcd/packet_send.c.
1135 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1137 * Redefined the Status Payload to include now two 8 bit fields,
1138 instead of one 16 bit field. This now makes it possible to
1139 send list of errors. Updated the protocol specs and the code
1140 in core library, client library and server. Protocol TODO #1.
1141 Affected files are lib/silccore/silccommand.[ch],
1142 lib/silcclient/command_reply.[ch], silcd/command.c,
1143 silcd/command_reply.c and silcd/packet_receive.[ch].
1145 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1147 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1148 must be handled by the application and should tell the application
1149 that an error message was already printed, and it should print the
1150 config coords (line, filename, ...). Affected files are
1151 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1153 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1154 server config parsing code more readable.
1156 Fixed a bug in the fetch_logging() config callback.
1158 Affected files is silcd/serverconfig.c.
1160 * Drop root privileges when started in foreground. Don't drop them
1161 if debugging also. Affected file is silcd/silcd.c.

1165 * Added more IM-like features by introducing new user modes
1166 for setting various presence information. Added new modes:
1167 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1168 specs and code. Protocol TODO #19. Affected files are
1169 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1170 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1172 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1174 * Added STATS command to the protocol after all, to return
1175 various statistical information about the network. It can
1176 be used by clients to retrieve statistical information, and
1177 servers may use it to to fetch cell and network wide
1178 statistics from router. Updated the protocol specs and
1179 implemented it to the server. Protocol TODO #16.
1180 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1181 silcd/command_reply.[ch].
1183 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * The LIST command reply in client libary now adds new channel
1186 entry if the returned channel doesn't exist yet in cache,
1187 and returns the channel entry to the application in the
1188 command_reply client operation. Affected file is
1189 lib/silcclient/command_reply.c.
1191 * Changed the channel message payload's MAC generation to
1192 include the IV in the MAC as well. This way all relevant
1193 parts of the channel message payload are authenticated also
1194 with the channel message MAC (and not only by packet MAC).
1195 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1196 Affected file is lib/silccore/silcchannel.c.
1198 * Fixed the SKE to save the remote version, since the
1199 silc_ske_parse_version mistakenly checked wrong version,
1200 after it replaced the start payload. Affected files are
1201 lib/silcske/silcske.[ch].
1203 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1205 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1206 string utility functions. Added there also new functions
1207 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1208 Affected files lib/silcutil/silcstrutil.[ch].
1210 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1211 files are lib/silcutil/silcstrutil.[ch].
1213 * Defined that the security property fields in SKE SHOULD be
1214 UTF-8 encoded, defined that version string MUST be US-ASCII
1215 encoded, defined that passphrases sent in connection
1216 authentication protocol MUST be UTF-8 encoded. Implemented
1217 these to the client and server. Defined also that other
1218 passphrases sent in the protocol MUST be UTF-8 encoded.
1219 Affected files are lib/silcske/silcske.c,
1220 lib/silcclient/protocol.c, silcd/protocol.c,
1221 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1223 * Changed the silc_client_close_connection interface to not
1224 need the SilcSocketConnection which should not be visible
1225 to application. Affected files are lib/silcclient/client.c
1226 and lib/silcclient/silcclient.h.
1228 * Rewrote the text for Private Message Key Payload in the
1229 protocol specification. Protocol TODO #11.
1231 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1233 * Upgraded the protocol version to 1.1, updated protocol specs
1236 * Added the nickname as new argument to NICK_CHANGE notify and
1237 added it to protocol specs and implemented it to client and
1238 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1239 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1240 lib/silcclient/client_notify.c.
1242 * Added the killer's client ID to the KILLED notify and added
1243 it to protocol specs and implemented it to client and server.
1244 Protocol TODO #13. Affected files are silcd/command.c,
1245 silcd/packet_receive.c, packet_send.[ch],
1246 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1247 The killer's client entry is now returned to application in
1248 the `notify' client operation.
1250 * Fixed the Max Argument fields that had too large value set
1251 in the protocol specs. Protocol TODO #14.
1253 * Added the LEAVE command reply to return the ID of parted
1254 channel. Updated protocol specs and implemented it to the
1255 client and server. Protocol TODO #15. Affected files are
1256 silcd/command.c, lib/silcclient/command_reply.c. The channel
1257 entry is now returned to application in the `command_reply'
1260 * Rewrote the version SKE version checking in client libary
1261 and in server to use the silc_parse_version_string. Affected
1262 files are lib/silcclient/protocol.c, silcd/protocol.c.
1264 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1265 commands that was missing it, and updated protocol specs and
1266 the server implementation. Protocol TODO #10. The affected
1267 file is silcd/command.c.
1269 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1270 generic reply to a generic request (REQUEST flag), and
1271 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1272 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1273 to define the payload for DATA flag. Added the flags to
1274 the implementation. Protocol TODO #9. Affected file is
1275 lib/silccore/silcchannel.h.
1277 Changed the client library to return the message length
1278 to application as well in the channel_message and private_message
1279 client operations. Affected files are
1280 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1281 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1282 and lib/silcclient/client_ops_example.c.
1284 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1285 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1286 the channel. Updated protocol specs and impelemented this
1287 to client and server. Protocol TODO #6. Affected files are
1288 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1289 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1291 Added new options m and M to CMODE command in Irssi SILC
1292 client to set these modes.
1294 * Deprecated all administrative commands from SILC protocol
1295 since they are highly implementation specific commands.
1296 Updated protocol specs. Moved the old commands in
1297 implementations to private range of command types. Affected
1298 files are silcd/command.c, lib/silcclient/command.c and
1299 lib/silcclient/command_reply.c. Protocol TODO #8.
1301 * Fixed a bug in server where sending unknown command crashes
1302 the server. Affected file silcd/command.c.
1304 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Added SILC_PROTOCOLVERSION macro to check protocol version
1307 of a socket connection. The affected file is
1308 lib/silcutil/silcsockconn.h.
1310 * Added better error logging in rekey protocol. Affected file
1313 * Do not check public key types in SKE during rekey. Affected
1314 file lib/silcske/payload.c.
1316 * Fixed the rekey protocol with PFS, which was totally broken.
1317 Affected file silcd/protocol.c.
1319 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1321 * Some client implementations quit network by doing first LEAVE
1322 and then immediately SIGNOFF (like Bombyx). We now do check
1323 after a short time after LEAVE notify and check whether the
1324 client is still valid after LEAVE, and if not we remove it from
1325 cache. Affected file is lib/silcclient/client_notify.c.
1327 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1329 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1330 it's good not to have security holes here.
1332 * Fixed a negative refcount situtuation for the config context.
1333 Affected file is silcd/serverconfig.c.
1335 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1337 * ROBOdoc documented lib/silcutil/silcutil.h.
1339 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1341 * Optimized even more the SilcPacketContext structure. Now
1342 totally saved 16 bytes of memory per context after optimization.
1343 Affected files are lib/silccore/silcpacket.[ch].
1345 * Made strict checks for valid SILC IDs. Affected file is
1346 lib/silccore/silcid.c.
1348 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1350 * Changed the object argument for silc_cipher_register,
1351 silc_hash_register, silc_hmac_register and silc_pkcs_register
1352 to const. Affected files are lib/silccrypt/silccipher.[ch],
1353 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1355 * Changed the silc_get_username and silc_get_real_name to
1356 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1358 * Fixed the Irssi SILC Client to use the silc_get_username and
1359 silc_get_real_name insted of glib routines since the glib
1360 routines only corrupt stack. Fixes the Irssi SILC to work in
1361 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1363 * Fixed the Irssi to not use g_get_home_dir since it crashes
1364 or returns garbage on cygwin and corrupts stack. Added function
1365 get_home_dir to Irssi routines. Affected files are
1366 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1368 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1370 * Made some structure optimizations. SFTP memory FS MemFSEntry
1371 entry structure. Optimized SilcTask structure. Optimized
1372 SilcPacketContext structure.
1374 Affected files lib/silcsftp/sftp_fs_memory.c,
1375 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1377 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1379 * And yet again reverted back the config thing since Johnny
1380 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1383 * Fixed memory leaks from config object. Affected files are
1384 silcd/serverconfig.[ch].
1386 * Added support for adding new connections to the server in rehash.
1387 After rehash they take effect.
1389 Added support for changing the maximum allowed connections in
1390 rehash. The number can grow but going smaller is not supported.
1392 Added function silc_server_num_sockets_by_remote to the
1393 silcd/server_util.[ch].
1395 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1397 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1399 * Added preliminary checking during config parsing for a valid
1400 public/private key and removed further checks in the code.
1401 Affected files are silcd/serverconfig.[ch], server.c.
1403 * Moved functions silc_server_drop() and silc_server_daemonise()
1404 from server.c to silcd.c since they are stricly related to
1405 the application activity.
1407 * Reverted a small part of the automatic ref/unref since
1408 it caused a double unref in some situations. Affected
1409 files are silcd/silcd.[ch], server.c, serverconfig.c.
1411 * Added some .cvsignore files in the lib directory.
1413 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1415 * Fixed silc_net_gethostbyaddr to correctly resolve by
1416 address. Affected file lib/silcutil/silcnet.c.
1418 * Fixed the notify relaying to client. The HMAC to be used
1419 with relayed packets ws wrong and caused decryption failure
1420 at the client end. Affected file is silcd/packet_receive.c.
1422 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1424 * Created new branch silc_protocol_1_0_branch.
1426 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1428 * Changed the silc_server_config_* routines to be SilcServer
1429 independent. They are now officially application specific code
1430 and not part of generic server implementation. Affected files
1431 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1433 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1435 * Added automatic referencing of config context in the
1436 silc_server_config_alloc, and automatic unreferencing in the
1437 silc_server_config_destroy. Affected files are
1438 silcd/serverconfig.[ch], silcd/silcd.c.
1440 * Fixed the silc_log_quick handling in the logging routines.
1441 It didn't log quickly when it was TRUE. Affected file is
1442 lib/silcutil/silclog.c. Also the flush delay was set even
1443 if it was 0 in config file. Affected file is
1444 silcd/serverconfig.c.
1446 * Added support for changing key pair of the server in rehash.
1447 Affected file silcd/server.c.
1449 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1451 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1452 too early, before getting the channel entry. Affected file
1453 is silcd/packet_receive.c.
1455 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1457 * Added functions silc_server_config_[ref/unref], these are used
1458 to prevent that the config object is destroyed.
1460 No longer directly affect global variables silc_log_quick and
1461 silc_log_delay, they are first cached inside the config object
1462 and then applied with silc_server_config_setlogfiles().
1464 silc_server_config_set_defaults() is now internal to
1465 serverconfig.c, there are no reasons to show this internal stuff
1468 Affected files are silcd/serverconfig.[ch].
1470 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1471 fprintf's to stderr, since some code may be executed again after
1472 the server went into the background. Affected files are
1475 * Added rehash support. Added function silc_server_rehash() that
1476 will perform all the basic tasks of the rehashing procedure.
1478 * Added command line option `-x, --hexdump'. This will enable the
1479 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1480 The option `--hexdump' implies `--debug'.
1482 * Fixed a bad bug in the logging APIs (silcutil library) where
1483 the application would crash after calling silc_log_reset_all().
1485 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1487 * Fixed the KICKED notify handling in client library to
1488 correctly remove the channel and all entries from the
1489 channel when I was kicked. This bug crashed the client.
1491 Fixed yet another but in KICKED notify handling to remove
1492 the kicked client correctly from the channel.
1494 Affected file is lib/silcclient/client_notify.c.
1496 * Fixed a minor bug in looking up correct client entry
1497 in KICKED notify in server. Affected file is
1498 silcd/packet_receive.c.
1500 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1501 sources correctly to distribution. Fixes --with-gmp option.
1503 * Removed the manual rehashing from ID Cache, and changed it
1504 to use the SILC Hash Table's auto rehash feature. Affected
1505 file is lib/silccore/silcidcache.c.
1507 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1509 * Fixed a bug in the silc_client_nickname_format function that
1510 handles the multiple same nickname formatting. Two clients
1511 with same nickname caused problems after the first one left
1512 and rejoined. It didn't format the nickname correctly.
1513 Affected file is lib/silcclient/idlist.c.
1515 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1517 * Don't change the topic if olod topic is same as new one.
1518 Affected file is silcd/packet_receive.c.
1520 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1522 * Added cross-reference support to the SILC Documentation
1523 generator. All types across all HTML files are now cross-
1524 referenced. Affected files util/robodoc/generator.c and
1525 scripts/silcdoc/silcdoc.
1527 * Added file lib/silcutil/silctypes.h to include all the
1528 arithmetic type definitions and some macros. Removed
1529 includes/bitmove.h and moved macros to silctypes.h.
1531 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1533 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1535 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1537 * Added `type' argument to silc_id_payload_parse_id function which
1538 now returns the type of the ID to the sent pointer. Affected
1539 file is lib/silccore/silcid.[ch].
1541 * Added check for CMODE_CHANGE notify type that mode change is
1542 allowed by the sender. Affected file silcd/packet_receive.c.
1544 * Added check for CUMODE_CHANGE notify type that mode change is
1545 allowed by the sender. Affected file silcd/packet_receive.c.
1546 Added the ID type as CUMODE_CHANGE notify type as argument
1547 to the `notify' client operation. Affected files are
1548 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1550 * Added function silc_client_add_server to the client library.
1551 Added support for resolving also channel and server info when
1552 received unknown entity in notify packet. Affected files are
1553 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1555 * Added function silc_command_get_status to return the command
1556 status from the command reply's argument payload. Affected files
1557 are lib/silccore/silccommand.[ch].
1559 * Added check for KICKED notify type that the kicking is
1560 allowed by the client. Affected file silcd/packet_receive.c.
1562 * Created function silc_get_input which can be used to get input
1563 (echo on or off) from user on command line. Affected files are
1564 lib/silcutil/silcutil.[ch].
1566 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1568 * Optimized silc_server_packet_relay_to_channel function.
1569 Added new function silc_channel_message_payload_encrypt which
1570 can be called directly if channel message payload needs to
1571 be encrypted and is already encoded (no need to call _encode
1572 function). Packet relaying is now done by router without any
1573 extra memory allocations. Affected files are
1574 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1575 silcd/packet_send.c.
1577 * Fixed the INVITE notify handling. It took wrong arguments
1578 as invite list and invite delete. Affected file is
1579 silcd/packet_receive.c.
1581 * Added check for TOPIC_SET notify type that the topic change is
1582 allowed by the client. Affected file silcd/packet_receive.c.

1585 the client. Affected file silcd/packet_receive.c.
1587 * Changed the silc_server_client_on_channel to return the
1588 SilcChannelClientEntry as well. Moved the function
1589 silc_server_check_cmode_rights to server_util.[ch].
1590 Affected files are silcd/server_util.[ch], silcd/command.c.
1592 * Added function silc_server_check_umode_rights to check whether
1593 changing client's user mode is allowed. Added check for
1594 UMODE_CHANGE notify type that the umode change is allowed
1595 by the client. Affected files are silcd/server_util.[ch],
1596 silcd/packet_receive.c and silcd/command.c.
1598 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1600 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1601 ID length. It ignored that ID can be IPv6 based as well.
1602 Affected file lib/silccore/silcpacket.h.
1604 * Fixed the silc_id_id2str and silc_id_str2id to take the
1605 IPv6 address offset's into consideration. Affecte file is
1606 lib/silccore/silcid.c.
1608 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1610 * Fixed the internal Unix scheduler functions to check for
1611 NULL context they may receive. The affected file is
1612 lib/silcutil/unix/silcunixschedule.c.
1614 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1616 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1617 can specify different directory with --home command line
1618 parameter. Affected files irssi/src/silc/core/client_ops.c,
1621 * SILC-specific commands aren't now executed if the active server
1622 isn't of SILC-type, so there won't be problems with having
1623 IRC and SILC protocol support in same client. Affected files
1624 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1627 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1629 * Improved the signal support in SILC Schedule. Added new
1630 function silc_schedule_signal_call which is used by application
1631 to mark a signal to be called. It is now safe to perform
1632 any kind of tasks in signal callbacks since it is guaranteed
1633 that the application specified signal callback is called
1634 after the signal is over. Affected files are
1635 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1637 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1639 * Added `name' field to SilcChannelPrivateKey to represent
1640 application given name for the key. Moved also the context from
1641 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1642 Added the `name' argument also to the function
1643 silc_client_add_channel_private_key.
1645 Added function silc_client_current_channel_private_key to set the
1646 current channel private key in use.
1648 Added "change" command to KEY command which can be used to change
1649 the current channel private key. Bound the command also to
1650 alt+K (Alt+Shift+k).
1652 Also affected files lib/silcclient/client_channel.c,
1653 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1655 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1657 * Added silc_rng_get_byte_fast function in to the
1658 lib/silccrypt/silcrng.[ch].
1660 * Changed the interface of silc_packet_assemble and the
1661 silc_packet_send_prepare. If silc_packet_assmble is now
1662 called the application does not call silc_packet_send_prepare
1663 because the library will call it automatically. These
1664 interfaces now also return a reference to the outgoing buffer
1665 which includes the assembled packet, which the application can
1666 use to encrypt the packet.
1668 Affected files are lib/silccore/silcpacket.[ch],
1669 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1670 silcd/packet_send.c, server_backup.c and packet_receive.c.
1672 * Fixed a packet sending bug on very high load, where outgoing
1673 packet queue wasn't handled correctly and packets got corrupted.
1674 Affected files are lib/silcutil/*/silc*sockconn.c,
1675 lib/silcclient/client.c and silcd/server.c.
1677 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1679 * Added macro SILC_PACKET_DATALEN which can be used during
1680 packet assembling to check whether the data to be added to
1681 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1682 len is truncated until it fits it.
1684 Added checks for maximum length of channel message payload and
1685 private message payload also.
1687 Added checks for maximum packet length in server and in
1690 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1691 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1692 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1693 lib/silcclient/client_prvmsg.c.
1695 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1697 * Added silc_server_packet_queue_purge call to the
1698 silc_server_disconnect_remote to assure that all data in the
1699 queue before disconnecting is sent to the network. Affected
1700 file silcd/server.c.
1702 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1704 * Added the deleting of server's own ID cache entry to the
1705 silc_server_free function. Free also everything else that
1706 has been allocated in silc_server_init. The affected file
1709 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1711 * Added functions silc_parse_version_string, silc_version_to_num,
1712 and silc_ske_parse_version to parse SILC protocol style version
1713 strings. Affected files lib/silcutil/silcutil.[ch] and
1714 lib/silcske/silcske.[ch].
1716 * Added new configuration params: version_protocol, version_software
1717 and version_software_vendor to specify what version the remote
1718 host must at least be to be able to connect to server. The vendor
1719 string can be regex matched too. Added new function
1720 silc_server_connection_allowed to check maximum number of allowed
1721 connections, and allowed versions for incoming connections.
1722 Affected files are silcd/server.c, server_util.[ch] and
1725 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1727 * Added preliminary support for signals in scheduler. The
1728 signals we care about are now blocked always when the scheduler
1729 is locked. This way we can synchronise the use of signal with
1730 scheduler. It is guaranteed that when signal occurs the scheduler
1731 is not locked, and thus new tasks can be safely added to the
1734 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1735 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1736 Added new platform specific routines
1737 silc_schedule_internal_signals_[un]block and
1738 silc_schedule_internal_signal_[un]register.
1740 Added new functions to SILC Schedule API:
1741 silc_schedule_signal_[un]register. Each signal that application
1742 is going to use should be registered to the scheduler.
1744 Affected files are lib/silcutil/silcschedule.[ch],
1745 lib/silcutil/*/silc*schedule.c.
1747 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1749 * Check for unauthenticated client and server in the
1750 silc_server_new_client and silc_server_new_server functions.
1751 Affected file silcd/packet_receive.c.
1753 * Added function silc_string_is_ascii to check whether given
1754 string is 7-bit ASCII string. Affected files are
1755 lib/silcutil/silcutil.[ch].
1757 * Added function silc_id_is_valid_server_id into the
1758 silcd/serverid.c and added checking for valid Server ID's in
1759 silc_server_new_server. The Server ID must always be based
1760 on the server's public IP address.
1762 * Added logging of DISCONNECT packet message in the server.
1763 Affected file silcd/server.c.
1765 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1767 * Changed all library interfaces that use Global RNG to also
1768 accept SilcRng as argument. Affected files are
1769 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1770 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1771 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1772 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1773 lib/silccrypt/rsa.c.
1775 * Added function silc_pkcs_generate_key to the
1776 lib/silccrypt/silcpkcs.[ch] for applications so that they
1777 don't need to do pkcs->pkcs->init calls anymore.
1779 * Remove SilcSocketConnection from the SFTP API since it really
1780 wasn't needed there. The application has the information
1781 saved in its contexts anyway and the SFTP layer doesn't need
1782 know about it. Affected files lib/silcsft/silcsftp.h and
1783 lib/silcsftp/sftp_[server/client].c.
1785 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1786 The SilcSimContext is not SilcSim.
1788 * Fixed possible buffer overflows in silc_id_render in the
1789 lib/silcutil/silcutil.c.
1791 * On EPOC the global crypto module lists are not used at all
1792 in the crypto library. Added support for using the constant
1793 algorithm list on EPOC. Affected files are
1794 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1797 * Fixed the handling of third parameter of KICKED notify, since
1798 it was mistakenly updated to SILC Protocol 1.0 even though it
1799 is to be included in 1.1. Since it is not in 1.0 it is not
1800 mandatory, and this fix now handles it only if it is provided,
1801 and it is not error if it is not provided. Affected file
1802 lib/silcclient/client_notify.c.
1804 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1806 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1807 client. Affected file irssi/src/silc/core/client_ops.c.
1809 * Merged with Irssi 0.8.4 from irssi.org CVS.
1811 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1813 * Check for valid socket connection in client entries before
1814 sending any messages. Fixes a crash, but doesn't fix some
1815 other underlaying bug that is lurking there. Affected
1816 file silcd/packet_send.c.
1818 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1820 * $usermode, $cumode and $cumode_space expandos shouldn't do
1821 anything with non-SILC server records. Affected file
1822 irssi/src/silc/core/silc-expandos.c
1824 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1826 * Fixed the silc_net_check_[host/local]_by_sock to support
1827 IPv6 bound sockets as well. Now they can return IPv6 addresses
1828 as well. Affected file lib/silcutil/silcnet.c.
1830 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1831 Affected lib/silcutil/unix/silcunixnet.c.
1833 * Fixed ID rendering (at least on some platforms, not NetBSD)
1834 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1836 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1838 * Added silc_hash_public_key and silc_hash_public_key_compare
1839 functions to be used with SilcHashTable. They can be used to
1840 hash public keys and compare public keys in hash table. Affected
1841 file lib/silcutil/silcutil.[ch].
1843 * Added support for specifying multiple public keys for Client
1844 connection section in server configuration file. This makes it
1845 possible to accept multiple public keys from same host, or to
1846 make a section that accepts any incoming host, and have the
1847 accepted public keys listed in the section.
1849 Added functions silc_sever_[find/get]_public_key, added the
1850 support for this actually to all connection sections but only
1851 the Client section is currently allowed to specify multiple
1854 Affected files are silcd/server.c, server_internal.h,
1855 command.c, protocol.c, server_util.[ch], packet_receive.c.
1857 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1859 * Merged Irssi 0.8.2 from irssi.org CVS.
1861 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1863 * If silc_debug is TRUE, also output standard logging messages
1864 to stderr with the debug output.
1866 Made silc_log_reset_all() flushing all channels before returning.
1867 Also fixed some documentation typos.
1869 Affected files are lib/silcutil/silclog.[ch].
1871 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1873 * Fixed the server to check correctly the amount of connections
1874 from single host, by checking also the type of the connection.
1875 Fixed also the comparison of number of connections and number
1876 of allowed connections. Affected files are silcd/server.c,
1879 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1881 * Fixed the USERS command reply to save the user's mode on the
1882 channel as well. Fixed JOIN command reply to check whether a
1883 client is on channel already and not join it twice. Affected
1884 file lib/silcclient/command_reply.c.
1886 * Added new file silc-expandos.c into irssi/silc/core/ to return
1887 various stuff for various signal for the statusbar etc. updating.
1888 Now Irssi SILC client prints channel user modes etc. on the
1891 * The user mode (like server/router operator changes) is now shown
1892 on the Irssi SILC client's statusbar. The affected files are
1893 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1895 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1897 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1898 to SILC_SCHEDULE_[UN]LOCK macros.
1900 * Added more error printing to logs in server code. Affected
1901 files silcd/server.c and silcd/protocol.c.
1903 * Fixed -S option parsing in Irssi SILC Client. Affected file
1904 irssi/src/silc/core/silc-core.c.
1906 * Added silc_buffer_alloc_size function. Affected file is
1907 lib/silcutil/silcbuffer.h.
1909 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1911 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1912 constants. Affected files in
1913 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1916 * Changed the internal SFTP Memory FS table to const. Affected
1917 file lib/silcsftp/sftp_fs_memory.c.
1919 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1921 * Fixed the buffer formatting and unformatting routines to
1922 check the size of 64 bits types with sizeof(). Affected
1923 file is lib/silcutil/silcbuffmt.c.
1925 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1927 * Removed 0.6.x backwards support.
1929 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1931 * Changed all integer type names:
1932 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1933 to avoid collisions with other libraries using same type names
1936 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1938 * Added `prefer_ipv6' argument to the functions
1939 silc_net_gethostbyname[_async]. If it is TRUE it will return
1940 IPv6 address over IPv4. If FALSE IPv4 address is returned
1941 even if IPv6 address was found. Affected files
1942 lib/silcutil/silcnet.[ch].
1944 * Added support silc_net_create_connection[_async] to fallback
1945 to IPv4 address if IPv6 address could not be used (like if
1946 it doesn't work on a specific system). Affected file in
1947 lib/silcutil/unix/silcunixnet.c.
1949 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1951 * Added silc_schedule_reinit function to do the enlarging
1952 of the max tasks handling capabilities of the scheduler.
1953 Affected files lib/silcutil/silcschedule.[ch].
1955 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1957 * Added automatic extern "C" { ... } for C++ compilers so the
1958 application does not need to define them. Affected file
1959 includes/silcincludes.h.
1961 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1962 old name went against naming convention. Applications now
1963 include "silcclient.h" instead of "clientlibincludes.h".
1964 Removed includes/clientlibincludes.h, it is redundant now.
1966 * Renamed includes/version.h to silcversion.h.
1968 * Added really preliminary support for OS/2 into the util
1969 library. Only thread & mutex API is implemented, others
1970 are still to be implemented. Created the lib/silcutil/os2/
1971 directory. Created also file includes/silcos2.h.
1973 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1975 * Added preliminary BeOS support into the util library.
1976 Created lib/silcutil/beos/, and implemented all the needed
1977 functions to support SILC on BeOS. Created also file
1978 includes/silcbeos.h.
1980 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1982 * Added proper initializations to silc's irssi code, so it's
1983 now possible to load it as module. Affected files
1984 irssi/src/silc/core/silc-core.c,
1985 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1987 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1989 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1992 * Fixed the silcdoc document generator to correct generate
1993 docs from all kinds of filenames. Affected files are
1994 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1996 * ROBOdoc documented lib/silcutil/silcmemory.h.
1997 Added also new function silc_memdup.
1999 * Removed lib/silcutil/silcbufutil.h and moved those routines
2000 to the lib/silcutil/silcbuffer.h.
2002 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Added `user_count' to the SilcChannelEntry which now tells the
2005 number of users on the channel. The user count is now saved
2006 in normal server of global channels as well. Affected files
2007 silcd/server.c, idlist.h, packet_receive.c and command.c.
2009 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2010 include file utility functions.
2012 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2013 instead of calling directly OS routines.
2015 * Fixed NICK change printing in Irssi SILC Client. Fixed
2016 KICKED notify printing in Irssi SILC Client. Affected file
2017 irssi/src/silc/core/client_ops.c.
2019 * Fixed a NICK change bug in client library, to not recreate the
2020 client_entry->channels hash table everytime nick is changed.
2021 Affected file lib/silcclient/client.c.
2023 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2025 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2026 the SKE interface a bit.
2028 * Fixed padding problem in PKCS#1. The padding was not actually
2029 random since the random number generator was used incorrectly.
2030 This security bug affects only when encrypting with PKCS#1, and
2031 it is not currently used at all in SILC. SILC only use signing
2032 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2034 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2036 * Rewrote the notify handling in Irssi SILC client to not call
2037 the events as signals. Fixes problems with Perl support.
2038 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
2040 * Send the auto-nicking NICK command in client library with
2041 little timeout after connecting. The affected file is
2042 lib/silcclient/client.c.
2044 * Added following new config file settings:
2045 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
2046 key_exchange_timeout, conn_auth_timeout, connections_max,
2049 Implemented all the new config settings handling in the server.
2051 Optimized the use of SKE Mutual flag usage. Use it only
2052 if connection authentication protocol is not based in public
2055 Renamed all SilcServerConfigSection* to SilcServerConfig*
2056 to have a bit shorter names.
2058 Affected files silcd/serverconfig.[ch], server.[ch], and
2061 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2063 * Cleaned up the listening sockets code, preparing for the rehash
2064 support. Affected file is silcd/server.c.
2066 * Fixed some output messages. Affected files are silcd/silcd.c,
2069 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2071 * Create lib/doc/silcrng_intro.html document as introduction
2072 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2074 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2076 * Fixes to the silcd config template. Affected file is
2077 doc/example_silcd.conf.in.
2079 * Removed type casts from silc_calloc(), conforming to the
2080 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2082 * Removed param_name member from client, server, and router
2083 section structs, now identifying the param directly.
2085 Added CONFIG_FREE_AUTH macro in config file parsing.
2087 Affected files are silcd/serverconfig.[ch].
2089 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2091 * Fixed command line parameter handling. All SILC initialization
2092 is now done in silc_core_init() which also fixes autoconnecting
2095 Affected files irssi/src/silc/core/silc-core.c,
2096 irssi/src/fe-text/silc.c.
2098 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2100 * Added new configuration options and blocks:
2101 keepalive_secs, reconnect_count, reconnect_interval,
2102 reconnect_interval_max, reconnect_keep_trying and
2103 require_reverser_lookup. Added ConnectionParam block, and
2104 implemented the connection parameters when connecting as
2105 initiator and when accepting connections as responder.
2107 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2108 whether given configuration value has been given already.
2110 Affected files silcd/serverconfig.[c], server.[c].
2112 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2113 algorithm parts and created new file silcalgs.conf, that
2114 is now included from the example_silcd.conf.in.
2116 * Optimized the silc_server_connect_to_router_second to take
2117 the connection configuration object from the SilcServerConnection
2118 object instead of finding it during the connecting phase.
2119 Added the configuration object to SilcServerConnection struct.
2120 Affected files silcd/server_internal.h, server.c.
2122 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2124 * Add the client on channel after it was resolved at the
2125 channel message receiving, and it was not already on the
2126 channel. Affected file lib/silcclient/client_channel.c.
2128 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2130 * Fixed the public key authentication to allocate always the

2136 * Unified the serverconfig.[ch]'s helper function interface.
2137 Affected file silcd/serverconfig.[ch].
2139 * Removed doc/example_silc.conf.in since it is redundant.
2140 The make install will now install irssi/silc.conf file.
2142 * Added new Passphrase and Publickey authentication methods to
2143 config file, allowing both public key and passphrase based
2144 authentication to be set at the same time.
2146 Added `prefer_passphrase_auth' setting in config file which
2147 can be used to set to prefer passwd auth if both passwd and
2148 public key is set. If not set, public key is preferred.
2149 This has effect only when being initiator (responder will try
2152 Added support for authentication with passphrase and public key
2153 at the same time. The passphrase is tried first always since
2154 it is faster to check.
2156 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2158 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2160 * Merged the new SILC Config library, with the server parsing
2161 support. Read the header file silcconfig.h or the toolkit
2162 documentation for the news. Affected files are

2171 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2173 * The silc_cipher_register, silc_hash_register and
2174 silc_hmac_register now checks if the object to be registered
2175 is registered already. Affected files are
2176 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2178 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2184 * Allow zero length channel messages inside the Channel Message
2185 Payload. Affected file lib/silccore/silcchannel.c.
2187 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2188 as header filenames.
2190 * Removed lib/silcclient/README and created HTML file
2191 lib/silcclient/silcclient_using.html, which is now included
2192 as part of Toolkit documentation.
2194 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2196 * Fixed CUMODE_CHANGE notify handling to change the mode of
2197 correct client. Affected file lib/silcclient/client_notify.c.
2199 * Make silc_rng_alloc fail if it cannot allocate the sha1
2200 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2202 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2204 * Fixed the file transfer's key agreement payload to include
2205 zero port also if the hostname is NULL because it could not
2208 Call file transfer monitor callback now also if error occurs
2209 during key agreement protocol.
2211 Changed the silc_client_file_send interface to return the
2212 SilcClientFileError instead of session id. The session ID
2213 is returned into pointer provided as argument.
2215 Check that the file exists locally before sending the
2216 file transfer request at all.
2218 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2220 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2221 error than can occur while key agreement protocol. Affected
2222 file lib/silcclient/silcapi.h.
2224 * Fixed the event_mode CMODE handler to not crash when mode
2225 is changed and +k mode is set in the channel. Affected file

2228 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2229 SILC_LOG_WARNING to give out Warning and not Error. Affected
2230 file lib/silcutil/silclog.c.
2232 * Fixed the channel message payload decryption in the function
2233 silc_channel_message_payload_decrypt to not modify the original
2234 buffer before it is verified that the message decrypted
2235 correctly. Otherwise, next time it is called with correct
2236 channel key it won't encrypt since the payload is corrupted.
2237 Affected file lib/silccore/silcchannel.c.
2239 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2241 * Do not constantly resize the window. A fix patch by cras.

2247 Affected file lib/silcutil/silcnet.c.
2249 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2251 * Fixed a bug in hash table internal routine for traversing
2252 the table with foreach callback. The current entry may
2253 become invalid in the callback but it was referenced after
2254 the callback returned.
2256 Do not allow auto rehashing of hash table during the
2257 silc_hash_table_foreach operation, for same reasons as it is
2258 not allowed for SilcHashTableList. Affected files are
2259 lib/silcutil/silchashtable.[ch].
2261 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2263 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2264 Win32 DLL. extern's in header files are now declared with
2267 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2269 * Fixed private message handling. It used some old code that
2270 caused the client to crash. Affecte file is
2271 lib/silcclient/client_prvmsg.c.
2273 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2275 * Added function silc_client_add_channel,
2276 silc_client_replace_channel_id, and removed functions
2277 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2278 from client library.
2280 * Added cross reference of the joined channels to the
2281 SilcClientEntry, and changed the SilcChannelEntry's
2282 users list to SilcHashTable. The affected files are
2283 lib/silcclient/idlist.[ch].
2285 * Fixed a bug in hash table tarversing. While the hash table
2286 is traversed with SilcHashTableList the table must not be
2287 rehashed. It is now guaranteed that auto rehashable tables
2288 are not rehashed while tarversing the list. Also defined that
2289 silc_hash_table_rehash must not be called while tarversing
2290 the table. Added function silc_hash_table_list_reset that must
2291 be called after the tarversing is over. The affected files are
2292 lib/silcutil/silchashtable.[ch].
2294 * Changed all hash table traversing to call the new
2295 silc_hash_table_list_reset in server and in client library.
2297 * Added function silc_client_on_channel to return the
2298 SilcChannelUser entry if the specified client entry is joined
2299 on the specified channel. This is exported to application as
2300 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2302 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2304 * Fixed founder regaining problem with JOIN command on normal
2305 server. The notify for mode change must be sent always and
2306 not only if !cmd->pending. Affected file silcd/command.c.
2308 * Fixed the WHOWAS command's reply sending to support the
2309 lists correctly. Affected file silcd/command.c.
2311 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2313 * When sending JOIN command to router for processing the
2314 sender's old command identifier was not saved back to the
2315 sender's command context, fixed now. The affected file is
2318 * Create the key in JOIN command of the router did not return
2319 the channel key, added check for this. Affected file is
2322 * Fixed a channel ID update bug in JOIN command reply. Do
2323 not directly upgrade the ID but call the function
2324 silc_idlist_replace_channel_id if the ID was changed.
2325 Affected file silcd/command_reply.c.
2327 * Fixed memory leaks from command calling if it would fail.
2328 Affected file silcd/command.c.
2330 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2332 * Applied patches from cras:
2334 Memory leak fixes around libaries, irssi window resize fix,
2335 new silclist.h and silcdlist.h, all extern inline changed to
2338 * Removed dotconf from lib/dotconf, not needed anymore.
2340 * Removed TRQ from lib/trq, not needed anymore.
2342 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2343 with server connections. Later this will be configurable
2344 in config file after new config file is done. Affected file
2347 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2349 * Fixed a crash in server related to channel announcements.
2350 Affected file silcd/server.c.
2352 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2354 * Fixed memory leaks in silc_server_create_new_channel*
2355 functions. Affected file silcd/server.c.
2357 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2358 which ID was changed. This way the router will send the
2359 user list for the channel again, and server won't be in
2360 desync in some rare circumstances. Affected file is
2361 silcd/packet_receive.c.
2363 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2365 * Check for NULL socket pointer in the function
2366 silc_server_packet_send_to_channel_real. Affected file
2367 silcd/packet_send.c.

2370 list. Affected file silcd/packet_receive.c.
2372 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2374 * Fixed some header addition to Toolkit distribution in
2375 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2377 * Added lib/silcclient/client_ops_example.h as an template
2378 file for application programmers to quickly start using
2379 the SilcClientOperation functions in their application.
2380 Updated the lib/silcclient/README as well to tell about this
2381 nice file made available.
2383 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2385 * Call silc_server_remove_from_channels when removing client
2386 entry when NO_SUCH_CLIENT_ID was received. Affected file
2387 is silcd/command_reply.c.
2389 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2391 * Added server & router operator statistics updating. Affected
2392 file silcd/packet_receive.c and silcd/command.c.
2394 * Fixed the SERVER_SIGNOFF notify handling on normal server
2395 not to save the history information for clients. Same was
2396 fixed earlier in remove_clients_by_server function, but not
2397 here. Affected file silcd/packet_receive.c.
2399 * Raised the default connection-retry count from 4 to 7 in
2400 server. Affected file silcd/server.h.
2402 * Cancel any possible reconnect timeouts when we start the
2403 key exchange. Affected file silcd/server.c.
2405 * Do not reconnect on connection failure when SCONNECT was
2406 given. Affected files silcd/server.[ch].
2408 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2410 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2412 * Fixed the NICK command to always give the unformatted
2413 nickname to the one giving the NICK command. If unformatted
2414 nickname is cached already it will be formatted and the
2415 local entry will always get the unformatted nickname.
2416 Affected file lib/silcclient/idlist.c.
2418 * Fixed some double frees from client library commands.
2419 Affected file is lib/silcclient/command.c.
2421 * Fixed CUMODE command in server to assure that no one can
2422 change founder's mode than the founder itself, there was a
2423 little bug. Affected file silcd/command.c.
2425 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2427 * Removed the SilcClientCommandDestructor from the client
2428 libary, it is not needed anymore. Affected files are
2429 lib/silcclient/silcapi.h, command[_reply].[ch],
2430 client_notify, idlist.c.
2432 * Fixed GETKEY command to first resolve client, and then
2433 resolve the server only if the client was not found, instead
2434 of resolving both at the same time. Affected file is
2435 lib/silcclient/command.c.
2437 * Added silc_client_start_key_exchange_cb and lookup the
2438 remote hostname and IP address before starting the key
2439 exchange with server. The affected file is
2440 lib/silcclient/client.c.
2442 * The server's public key is now saved using the IP address
2443 of the server and not the servername for the filename.
2444 The hostname public key filename is checked as an fall back
2445 method if the IP address based filename is not found.
2447 Fixed the GETKEY command to save the fetched server key
2448 in correct filename.
2450 Print the remote server's hostname now when new key is
2451 received during connection process. Affected file is
2452 irssi/src/silc/core/client_ops.c.
2454 * Return always our own public key to the client if it asks
2455 for it with GETKEY command. Affected file silcd/command.c.
2457 * Removed the use_auto_addr variable from default config
2458 file since it was in wrong section. Affected file is
2461 * Fixed TOPIC_CHANGE notification to not route it when it
2462 was sent using silc_server_send_notify_to_channel function.
2463 Affected file silcd/command.c.
2465 * Fixed silc_server_send_notify_kicked to send the kicker's
2466 Client ID also, it was missing. Affected files are
2467 silcd/command.c, silcd/packet_send.[ch].
2469 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2471 * Do not save client history information in SERVER_SIGNOFF.
2472 Fixes the bug in normal server that it does not detect
2473 the client becoming valid after the server becomes back
2474 online. Affected file silcd/server_util.c.
2476 * Added `sock_error' field into the SilcSocketConnection
2477 context. When error occurs during socket operation (read
2478 or write) the error is saved. Added also new function
2479 silc_socket_get_error to return human readable socket error
2480 message. Affected files are lib/silcutil/silcsockconn.[ch],
2481 lib/silcutil/unix/silcunixsockconn.c, and
2482 lib/silcutil/win32/silcwin32sockconn.c.
2484 * The server now prints the socket error message in the
2485 signoff for client. Affected file silcd/server.c.
2487 * Fixed the `created' channel information sending from router
2488 to server in JOIN command. Checks now whether the channel
2489 really was created or not and set it according that.
2491 Fixed the JOIN command to use the client entry's current
2492 ID during the joining procedure instead of the one it sent
2493 in the command (it is checked though), since it can change
2494 between the packet processing and command processing, and
2495 would just case unnecessary pain in the client end. Affected
2496 file silcd/command.c.
2498 * Fixed a channel key payload sending to use correct channel
2499 ID when the server was forced to change the channel's ID by
2500 router. Router sent the key payload with the old Channel ID.
2501 Affected file silcd/packet_receive.c.
2503 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2505 * Call silc_server_save_channel_key only if the key payload
2506 was provided in the JOIN command's command reply. Affected
2507 file silcd/command_reply.c.
2509 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2511 * Fixed silc_mp_sizeinbase to return the value correctly with
2512 MPI. Affected file lib/silcmath/mp_mpi.c.
2514 * Fixed the stop_server signal to correctly stop the scheduler
2515 and gracefully stop the server when SIGTERM or SIGINT signals
2516 are received. Affected file silcd/silcd.c.
2518 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2520 * Simple handling of TERM and HUP signals. Also added some log
2521 flushing call around. Affected file is
2524 * Fixed small bugs in silclog.c. Now buffering output will take
2525 effect after 10 seconds since startup: This will ensure that
2526 no important startup messages are lost. Also output redirection
2527 will preserve original format ([Date] [Type] message).
2528 Affected file is lib/silcutil/silclog.c.
2530 * Added two options to the config file, in the logging section:
2531 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2532 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2534 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2536 * Do not print the warning about log files not being initialized
2537 more than once to avoid excess logging. Affected file is
2538 lib/silcutil/silclog.c.
2540 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2541 the SIM copying in make install in Makefile.am.pre.
2543 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2545 * Rewritten silclog APIs. Globally interesting changes follows:
2546 silc_log_set_files() changed to silc_log_set_file().
2547 silc_log_set_callbacks() changed to silc_log_set_callback().
2548 ROBOdoc documented silclog header file.
2549 SilcLogCb now returns bool to wether inihibit the default
2550 handler or not (to keep the old behaviour return always TRUE).
2551 The new APIs should also fix the problem of the
2552 silcd_error.log file that was written in the current directory.
2555 Log files streams will remain opened after silc_log_set_file()
2556 call, means less CPU usage notably on high traffic servers.
2557 File streams are now full buffered, and flushed to the disk
2558 every 5 minutes, lesses HD activity and CPU usage.
2559 Messages can be redirected, allowing admins to configure
2560 one single logfile for all server messages.
2561 the silc_log_quick global variable to activate fast-logging.
2562 Affected files lib/silcutil/silclog.[ch]
2564 * Changed some code to conform new silclog APIs. Affected
2565 files are doc/example_silcd.conf.in, silcd/server.c
2566 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2569 * Fixed a memory leak that could occur in some situations.
2570 Affected file silcd/serverconfig.c.
2572 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2574 * Added the silc_client_del_client to remove the client from
2575 all channels as well. Affected file lib/silcclient/idlist.c.
2577 * Fixed the client library to correctly remove the client
2578 from all channels when the client entry is being destroyed.
2579 Affected file lib/silcclient/client_notify.c, command.c.
2581 * Added auto-nicking support to the client library. If the
2582 applicatio now sets client->nickname it will be sent to the
2583 server after connecting by the library. This way for example
2584 SILCNICK (or IRCNICK) environment variables will have effect
2585 and always change the nickname automatically to whatever
2586 it is wanted. Affected file lib/silcclient/client.[ch].
2588 * Renamed silc_server_command_bad_chars to the
2589 silc_server_name_bad_chars and moved it to the
2590 silcd/server_util.[ch]. Added also new function
2591 silc_server_name_modify_bad to return nickname that
2592 includes bad characters as new nickname without those
2593 bad characters. This check and modify is now used in
2594 silc_server_new_client when the username is initially set
2595 as nickname, so it must be checked to be valid nickname.
2596 Affected file silcd/packet_receive.c.
2598 * The nickname length is now taken from the packet for real
2599 and not trusted to strlen() since it clearly can return
2600 wrong length for nickname including bad characters. This
2601 also applies to channel names. Affected file silcd/command.c.
2603 * Removed the lib/silcsilm/modules directory. Modules are now
2604 compiled into the lib/silcsim. Fixed the copying of the
2605 modules to follow symbolic links in Makefile.am.pre.
2607 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2609 * Fixed silc_string_regexify list creation. Fixes bugs with
2610 BAN and INVITE commands in server. The affected file is
2611 lib/silcutil/unix/silcunixutil.c.
2613 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Removed the command destructor entirely from the server's
2616 command and command reply routines. It is not needed, and
2617 its usage was buggy and caused crashes. Affected files are
2618 silcd/command[_reply].[ch].
2620 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Cancel protocol and NULL sock->protocol if timeout
2623 occurred during protocol. Affected file silcd/server.c.
2625 * Cancel protocol timeouts always before calling the final
2626 callback, to assure that after final callback is called
2627 no other state will be called for the protocol anymore.
2628 Affected file silcd/protocol.c.
2630 * Print error log if incoming connection configuration could
2631 not be found. Affected file silcd/server.c.
2633 * Fixed JOIN command to correctly save the founder mode
2634 to the client on normal SILC server, when the channel
2635 was created by the router. Affected file silcd/command.c.
2637 * Fixed LIST command (hopefully) to send correct reply
2638 packets. Affected file silcd/command.c.
2640 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * The silc_packet_receive_process now returns FALSE if the
2643 read data was invalid packet, and TRUE if it was ok.
2645 The server now checks that if unauthenticated connection
2646 sends data and its processing fails the server will close
2647 the connection since it could be a malicious flooder.
2649 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2651 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Make sure the warning about error opening a log file is
2654 printed only once and not everytime it fails (produces
2655 too much useless log). Affected file lib/silcutil/silclog.c.
2657 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2659 * Made the silc_server_daemonise() function more readable.
2660 Affected file silcd/server.c.
2662 * Pid file is now optional, the user may comment it out from
2663 the config file. Removed define SILC_SERVER_PID_FILE, we
2664 don't need a default any longer. Affected file
2665 configure.in.pre, lib/Makefile.am.pre.
2667 * Make some use of the pid file. The server now dies at startup
2668 if it detects a valid pid file on his path. The server would
2669 die anyway in this circumstance, because of the bind() failure.
2670 Affected file silcd/silcd.c.
2672 * No longer compiling lib/dotconf.
2674 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2676 * Fixed JOIN command parsing not to crash. Affected file
2677 lib/silcclient/command.c.
2679 * Fied the NICK_CHANGE notify to add the new client entry
2680 even it is resolved. This removes an <[unknown]> nick
2681 thingy bug in the client. Affected file is
2682 lib/silcclient/client_notify.c.
2684 * Do not try to allocate 0 bytes (efence does not like it)
2685 in lib/silccore/silccomand.c when encoding payload.
2687 * Do not take IRCNICK as nickname in Irssi SILC client since
2688 it is not possible to set nickname before hand connecting
2689 the server (TODO has an entry about adding auto-nicking
2692 * Changed the silc_server_command_pending to check whether
2693 there already exists an pending entry with the specified
2694 command, command identifier and pending callback. This is
2695 to fix IDENTIFY and WHOIS related crashes that may register
2696 multiple pending commands with same identifier. Affected
2697 file silcd/command.c.
2699 * Fixed the server to reconnect to the router even if it
2700 was already reconnecting and EOF was received. This to
2701 fix a possibility that the server wouldn't ever try to
2702 auto-reconnect to the router. Affected file silcd/server.c.
2704 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2706 * Fixed the server's password authentication to use the
2707 length of the locally saved password, and not the one
2708 sent in the packet. Affected file silcd/protocol.c.
2710 * Fixed same password authentication problem in the
2711 Authentication Payload handling routines in
2712 lib/silccore/silcauth.c.
2714 * Yet another password authentication problem fixed with
2715 channel password handling in silcd/command.c.
2717 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2719 * If first character of string in silc_parse_userfqdn is '@'
2720 then do not parse it. Affected file is
2721 lib/silcutil/silcutil.c.
2723 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Fixed minor bug in IDENTIFY command reply sending, which
2726 caused various weird problems during JOIN when it was
2727 resolving names for users. Affected file silcd/command.c.
2729 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Fixed the IDENTIFY command reply sending to chech better valid
2732 clients. It was possible to send incomplete list of replies.
2733 Affected file silcd/command.c.
2735 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Added silc_client_command[s]_[un]register functions now to
2738 dynamically register the commands in client library. Removed
2739 the static table of commands. This allows the client library
2740 to call commands without causing the application to know about
2741 what commands library has called.
2743 Removed the INFO command reply kludge to detect when the command
2744 was called by library. Now library use its own command reply
2745 function for INFO command.
2747 Added function silc_client_command_call to call a command.
2748 Application can use it to call command, not access the structure
2751 Now all commands that are sent by the client library (not
2752 explicitly sent by application) use own command reply functions.
2754 Affected files around lib/silcclient/ and in
2755 irssi/src/silc/core/.
2757 * Fixed the WHOIS command reply sending to chech better valid
2758 clients. It was possible to send incomplete list of replies.
2760 Fixed the WHOIS and IDENTIFY to send the request to router
2761 if normal server did not do it and did not find any results.
2763 Affected file silcd/command.c.
2765 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Moved the internal data from SilcClient context into its
2768 own file, not accesible to application. Affected files
2769 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2770 and other files in client library.
2772 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Added doc/examples installation target in Makefile.am.pre.
2777 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2780 commands the found client entry will be removed from the
2781 cache, after notifying application about the error. Affected
2782 file lib/silcclient/command_reply.c.
2784 * Changed the /MSG to check for exact nickname user gave, and
2785 not let `nick' match `nick@host' if it is only one found. Now,
2786 user must type the exact nickname (like nick@host2) even if
2787 there are no more than one same nicks found. This is to avoid
2788 a possibility of sending nickname to wrong nickname since
2789 `nick' could match `nick@host'. Affected file is
2790 irssi/src/core/silc-servers.c.
2792 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Do not print "you are now server operator" or similar when
2795 giving /away command. Affected files are
2796 irssi/src/silc/core/client_ops.c, silc-servers.h.
2798 * Made the silc_server_command_pending_error_check to send
2799 the same command reply payload it received back to the
2800 original sender of the command. This way all arguments
2801 that was received by the server will be received by the
2802 client too. Affected file silcd/command.c.
2804 * Added the silc_idcache_add to return the created cache entry
2805 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2807 * Add global clients to expire if they are not on any channel.
2808 This is because normal server will never know if they signoff
2809 if they are not on any channel. The cache expiry will take
2810 case of these entries. This is done by normal servers only.
2811 The affected files are silcd/command_reply.c,
2812 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2814 * If server receives invalid ID notification for WHOIS or
2815 IDENTIFY and the ID exists in the lists, it is removed.
2816 Affected file silcd/command_reply.c.
2818 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2819 in client then client entry that it matches is searched and
2820 the nickname is printed on the screen for user. Affected
2821 file irssi/src/silc/core/client_ops.c.
2823 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2825 * Use cache entry expire time in the LIST command reply to
2826 purge old entries from the cache after the LIST command
2827 reply has been received. This way we don't have non-existent
2828 entries in the cache for too long. Affected file is
2829 silcd/command_reply.c.
2831 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * If we are normal server, and we've not resolved client info
2834 in WHOIS or IDENTIFY from router, and it is global client,
2835 we'll check whether it is on some channel. If it is not
2836 then we cannot be sure about its validity and will resolve it
2837 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2838 file silcd/command.c.
2840 * Search channel by name (if possible) rather than by ID
2841 in IDENTIFY command's command reply. Affected file is
2842 silcd/command_reply.c.
2844 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2847 Updated specs and implemented it. Affected file silcd/command.c,
2848 silcd/packet_send.c and silcd/packet_receive.c.
2850 * Implemented the <founder auth> payload handling in the JOIN
2851 command. If provided all conditions for channel joining
2852 except requirement to provide correct passphrase can be
2853 overrided by the channel founder. Updated the protocol specs.
2854 Affected file silcd/command.c.
2856 Added support for founder auth in JOIN command in client
2857 library. Fixed the parsing of the JOIN command now to support
2858 all options as they should be. The affected file is
2859 lib/silcclient/command.c.
2861 * Optimized the WHOIS and IDENTIFY commands to send the request
2862 to router only if it includes nicknames or other names. If
2863 they include only IDs then check the local cache first before
2864 routing. Affected file is silcd/command.c.
2866 * Added channels topic announcements. Affected file is
2867 silcd/packet_receive.c and silcd/server.c.
2869 * Fixed the silc_server_send_notify_topic_set to really destine
2870 the packet to channel. Affected file silcd/packet_send.c.
2872 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2873 library. Affected file lib/silcclient/client_notify.c.
2875 * Added UMODE announcements. Affected file silcd/server.c.
2877 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Memory leak fixes in:
2881 lib/silcutil/silcsockconn.c
2882 lib/silcske/silcske.c
2883 lib/silcske/groups.c
2885 lib/silccrypt/silcpkcs.c
2886 lib/silccore/silccommand.c
2887 lib/silccore/silcidcache.c
2892 * ROBOdoc documented the lib/silcske/groups.h file and a
2893 bit changed the interface for better.
2895 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2897 * Update the client entry context in the ID cache after
2898 nick change. Affected file lib/silcclient/command.c.
2899 Fixes the CUMODE command when regaining founder privileges,
2900 and a little WHOIS problem.
2902 * Fixed silc_net_gethostbyname to correctly call the
2903 inet_ntop. Affected file lib/silcutil/silcnet.c.
2905 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2907 * Added IPv6 support checking to the configure.in.pre, added
2908 also --enable-ipv6 option to override the check. Affected
2909 file configure.in.pre.
2911 * The silc_thread_create now calls the start function
2912 directly if threads support is not compiled in. Removes
2913 ugly #ifdef's from generic code. Affected files are
2914 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2916 * Added silc_net_gethostby[name/addr]_async to asynchronously
2917 resolve. Affected files are lib/silcutil/silcnet.[ch].
2919 * Added support for rendering IPv6 based server, client and
2920 channel IDs. Affected file lib/silcutil/silcutil.c.
2922 * Added support for creating IPv6 based server IDs. Affected
2923 file is silcd/serverid.c.
2925 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2927 * Added silc_net_gethostby[addr/name] into the
2928 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2929 routines. Added silc_net_is_ip[4/6]. Affected file is
2930 lib/silcutil/unix/silcunixnet.c. All routines that take
2931 address as argument now supports both IPv4 and IPv6 addresses.
2933 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2935 * Fixed LIST command reply sending in server. Affected file
2938 * Server now sends the kicker's client ID in the KICK notify
2939 to the kicked client. Affected file silcd/command.c.
2941 * The client library now parses the kickers client ID and
2942 UI displays it. Affected files lib/silcclient/client_notify.c
2943 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2945 * Made all payload parsing function prototypes consistent.
2946 They all take now const unsigned char * and uint32 pair as
2947 the payload data instead of SilcBuffer. Changes all around
2948 the source tree. Other unsigned char* -> const unsigned char*
2949 changes around the tree as well.
2951 * Optimized SFTP client and server packet sending not to
2952 allocate new buffer for each packet but to recycle the
2953 first allocated buffer. Affected files are
2954 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2956 * Optimized the SFTP client to use SilcList instead of
2957 SilcDList for requests, because it is faster. Affected file
2958 is lib/silcsftp/sftp_client.c.
2960 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2961 into lib/silccore/silcid.[ch].
2963 Renamed silcpayload.[ch] into silcargument.[ch].
2965 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * If client entry is deleted with active key agreement
2968 session, abort the session.
2970 The silc_client_abort_key_agreement now calls the completion
2971 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2973 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2976 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Don't use __restrict in older GCC's. Affected file is
2979 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2981 * silc_net_localhost now attempts to reverse lookup the
2982 IP/hostname. Affected file lib/silcutil/silcnet.c.
2984 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2985 command. It can be used to gain founder privileges at
2986 the same time when joining the channel.
2988 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2989 kicker's client ID as well. Updated protocol specs.
2991 Defined that the server must send SILC_COMMAND_IDENTIFY
2992 command reply with error status to client who sent
2993 private message with invalid client ID.
2995 Updated the protocol specification.
2997 * Added silc_server_send_command_reply to send any
2998 command reply. Affected file silcd/packet_send.[ch].
3000 * Added silc_id_payload_encode_data to encode ID payload
3001 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3003 * The server now send IDENTIFY command reply with error
3004 status if client ID in private message is invalid. Affected
3005 file silcd/packet_receive.c.
3007 * Save the server key file with server's IP address in
3008 the filename instead of hostname. The affected file is
3009 irssi/src/silc/core/client_ops.c.
3011 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3016 * Added libtool support for compiling shared objects in
3017 lib/silcsim. Affected file configure.in.pre and
3018 lib/silcsim/Makefile.am. Original patch by cras.
3020 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Pid file configuration, and server's config file fixes
3023 patch by toma. Updated CREDITS file.
3025 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Fixed silc_client_channel_message to not try to decrypt
3028 the message twice if it resolved the destination client
3029 information. This could cause of dropping one channel
3030 message. Affected file lib/silcclient/client_channel.c.
3032 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3035 lib/silcclient/client.c. This function is used when the SILC
3036 Client is run under some other scheduler, or event loop or
3037 main loop. On GUI applications, for example this may be
3038 desired to used to run the client under the GUI application's
3039 main loop. Typically the GUI application would register an
3040 idle task that calls this function multiple times in a second
3041 to quickly process the SILC specific data.
3043 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3045 * Fixed silc_server_drop() for dropping the supplementary
3046 groups as well, this could cause a security hole on some
3049 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3054 * Write PID file after dropping privileges. Added -F option
3055 to run server on foreground. A patch by debolaz.
3056 Affected files silcd/server.c, silcd/silcd.c.
3058 * Fixed MOTD to return the MOTD file server name. Affected
3059 file silcd/command.c.
3061 * Added INFO command reply handling to the Irssi SILC Client.
3062 Affected file irssi/src/silc/core/client_ops.c.
3064 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Fixed the silc_idcache_list_* routines to really support
3067 the dynamic list. Fixes a crash. Affected file is
3068 lib/silccore/silcidcache.c.
3070 * Fixed the LIST command reply to really call LIST command's
3071 pending callbacks. Affected file silcd/command_reply.c.
3073 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Update conn->local_entry->nickname after giving NICK
3076 command. Affected file lib/silcclient/command.c.
3078 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3080 * Added the [pid] option to the silcd configuration file
3082 Affected files: serverconfig.[ch] and silcd.c
3084 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Save fingerprint in WHOIS command reply in server.
3087 Affected file silcd/command_reply.c.
3089 * Fixed NICK commands pending callback registration.
3090 Affected file lib/silcclient/command.c.
3092 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Use ++server->cmd_ident when sending commands in server,
3095 instead of random number. Affected file silcd/command.c.
3097 * Fixed GETKEY command reply to call actually GETKEY pending
3098 command callbacks. Affected file silcd/command_reply.c.
3100 * A bit stricter check for nicknames. Check for same nickname
3101 in NICK command also. Affected file silcd/command.c.
3103 * Do not call INFO command everytime client ID changes, only
3104 during first connecting. Affected file lib/silcclient/client.c.
3106 * Set the new nickname only after successful command reply for
3107 NICK command is returned by server. Affected file
3108 lib/silcclient/command.c.
3110 * Remove nicknames from nicklist during server_signoff notify.
3111 Should fix /NAMES bit more. The affected file is
3112 irssi/src/silc/core/silc-channels.c.
3114 * Added `fingerprint' field to the SilcIDListData in the
3115 silcd/idlist.h to hold the fingerprint of the client's
3118 Send the fingerprint of the client's public key in WHOIS
3121 Affected files silcd/command.c, and silcd/idlist.[ch].
3123 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3124 create fingerprint from given data.
3126 * Show the fingerprint of the client's public key in WHOIS.
3127 Affected files irssi/src/module-formats.[ch] and
3128 irssi/src/silc/core/client_ops.c.
3130 * Format the multiple same nicknames also during JOIN and
3131 NICK_CHANGE notifys. Affected file is
3132 lib/silcclient/client_notify.c.
3134 * Do not print error on screen for invalid private message
3135 payload since it can come if someone is sending private
3136 messages with wrong key. Affected file
3137 lib/silccore/silcprivate.c.
3139 * Fixed multiple concurrent /PING crash. Affected file
3140 lib/silcclient/command.c.
3142 * Changed the wrong ID encoding. All IP addresses must be
3143 in MSB first order in encoded format. They were encoded
3144 wrong and was in LSB format. Affected files are
3145 silcd/serverid.c, lib/silcutil/silcutil.c.
3147 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3149 * Call the `connect' client operation through the scheduler
3150 in case of error. Affected file lib/silcclient/client.c.
3152 * Call the `failure' client operation even if the error
3153 occurred locally during a protocol. Affected file is
3154 lib/silcclient/protocol.c.
3156 * Added support of sending LIST command to router from normal
3157 server. This way normal server can get list of all channels
3158 in the network too. Fixed the channel list sending in the
3159 server too. Affected files are silcd/command.c, and
3160 silcd/command_reply.[ch].
3162 * Added silc_server_update_channels_by_server and
3163 silc_server_remove_channels_by_server. They are used during
3164 disconnection of primary router and in backup router protocol.
3165 Affected file silcd/server_util.[ch], silcd/server.c and
3166 silcd/server_backup.c.
3168 * Fixed channel adding to global list in IDENTIFY command
3169 reply in server. Affected file silcd/command_reply.c.
3171 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * If the incoming packet type is REKEY or REKEY_DONE process
3174 that packet always synchronously. Fixes yet another MAC
3175 failed error on slow (dialup) connections. Affected file
3176 lib/silcclient/client.c and silcd/server.c.
3178 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3180 * Call check_version SKE callback for initiator too. Affected
3181 file lib/silcske/silcske.c.
3183 * Implemented fix for security hole found in the SKE that was
3184 fixed in the specification few days back; the initiator's
3185 public key is now added to the HASH value computation.
3186 Added backwards support for the old way of doing it too, for
3187 old clients and old servers. Affected file is
3188 lib/silcske/silcske.c.
3190 * Enabled mutual authentication by default in SKE. If initiator
3191 is not providing mutual authentication the responder will
3192 force it. This will provide the proof of posession of the
3193 private key for responder. The affected files are
3194 lib/silcclient/protocol.c and silcd/protocol.c.
3196 * Do not cache anymore the server's public key during SKE.
3197 We do mutual authentication so the proof of posession of
3198 private key is done, and if the server is authenticated in
3199 conn auth protocol with public key we must have the public
3200 key already. Affected file silcd/protocol.c.
3202 * Added new global debug variable: silc_debug_hexdump. If
3203 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3204 file lib/silcutil/silclog.[ch].
3206 * Fixed compilation warning due to char * -> const char *.
3207 Affected files lib/silcutil/silcnet.h, and
3208 lib/silccore/silcauth.[ch].
3210 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Fixed CMODE command when new channel key was created. If
3213 the creation failed the old key was removed. Next time giving
3214 same command would crash the server since the old key was
3215 freed already. Affected file silcd/command.c.
3217 * Fixed the silc_server_announce_get_channels to not crash
3218 on reconnect. Affected file silcd/server.c.
3220 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3222 * Added silc_log_set_debug_string function to set a regex
3223 string to match for debug output. Only the function names,
3224 or filenames matching the given debug string is actually
3225 printed. This way it is possible to filter out those debug
3226 strings that user is not interested in.
3228 Fixed a bug in silc_string_regexify.
3230 Affected files lib/silcutil/silclog.[ch], and
3231 lib/silcutil/unix/silcunixutil.c.
3233 * Changed the -d options in both server and Irssi SILC client
3234 to take the debug string as argument. Affected files
3235 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3237 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * Added silc_hash_babbleprint to create a Bubble Babble
3240 Encoded fingerprint. The encoding is developed by Antti
3241 Huima (draft-huima-babble-01.txt), and it creates human
3242 readable strings out of binary data. Affected file
3243 lib/silccrypt/silchash.[ch].
3245 * Print the babble print now in addition of fingerprint as well
3246 in Irssi SILC client. Affected files are
3247 irssi/src/fe-common/silc/module-formats.[ch],
3248 irssi/src/fe-common/silc/core/client_ops.c.
3250 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3252 * Fixed a security problem found in SKE. The initiator's
3253 public key too is now added to the HASH hash value creation
3254 which is signed by the responder to create the SIGN value.
3255 This will prevent anyone in the middle to lie to the responder
3256 about the initiator's public key. If this is done now, the
3257 man in the middle will get caught. Updated the protocol
3260 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * Better installation directory handling. Configure module
3263 paths and other paths automatically to example_silc* files
3264 in doc/. A patch by toma.
3266 * Fixed compiler warning from MPI library, and from SILC RNG.
3269 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3270 It can be configured with ./configure. A patch by toma.
3272 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Find correct make to use in prepare-clean. A patch by
3275 toma. Affected file prepare-clean.
3277 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3279 * Added irssi variables use_auto_addr, auto_bind_ip,
3280 auto_bind_port and auto_public_ip.
3282 * Changed the interface for silc_client_send_key_agreement
3283 in lib/silcclient/silcapi.h
3287 irssi/src/silc/core/silc-core.c
3289 lib/silcclient/silcapi.h
3290 irssi/src/silc/core/silc-channels.c
3291 lib/silcclient/client_keyagr.c
3294 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Added silc_pkcs_public_key_compare to compare two
3297 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3299 * Check that the client who set the founder mode on the
3300 channel is the same client that is giving the founder
3301 mode to itself. It is done by comparing the saved public
3302 key (it is saved even in the authentication is passphrase).
3303 Affected file silcd/command.c.
3305 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * Do not process packet for disconnected socket connection.
3308 Affected file lib/silccore/silcpacket.c.
3310 * Process the DISCONNECT packet through scheduler in the
3311 client library. Affected file lib/silcclient/client.c.
3313 * Fixed the silc_client_packet_parse to not to increase
3314 the packet sequence number if the conn->sock and the
3315 current socket connection is not same. This can happen
3316 for example during key agreement when the conn includes
3317 multiple socket connections (listeners). Affected file
3318 lib/silcclient/client.c.
3320 * The sender of the file transfer request now provides also
3321 the pointer (listener) for the key exchange protocol. If
3322 the listener cannot be created then it sends empty key
3323 agreement and lets the receiver provide the listener.
3325 Added `local_ip' and `local_port' arguments to the
3326 silc_client_file_send. If they are provided they are used,
3327 if not then it will attempt to find local IP address, if
3328 not found or bind fails then the remote client will provide
3331 Affected files are lib/silcclient/client_ftp.c and
3332 lib/silcclient/silcapi.h.
3334 * Extended the FILE SEND command to support defining the
3335 local IP and port for key exchange listener. They are
3336 optional. Affected file irssi/src/silc/core/silc-servers.c.
3338 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Defined to WHOIS command reply the sending of fingerprint
3341 of the client's public key (if the proof of posession of the
3342 corresponding private key is verified by the server).
3343 Updated to the protocol specification.
3345 * Added support of receiving the client's public key's
3346 fingerprint in command reply in client library. Affected
3347 file is lib/silcclient/command_reply.c, and
3348 lib/silcclient/idlist.[ch].
3350 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Do not send over 128 chars long nickname to the server
3353 in NICK command. Affected file lib/silcclient/command.c.
3355 * Do not send over 256 chars long channel names to the server
3356 in JOIN command. Affected file lib/silcclient/command.c.
3358 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Assure that silc_server_close_connection cannot be called
3361 twice for same socket context. Affected file is
3364 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3366 * Send error message to application if opening file for
3367 writing during file transfer fails. Affected file is
3368 lib/silcclient/client_ftp.c.
3370 Remove all file transfer sessions for a client that we're
3371 removing from ID cache.
3373 Affected file is lib/silcclient/client_ftp.c.
3375 * Fixed silc_net_addr2bin to return correct address. Affected
3376 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3378 * Fixed file transfer session removing on signoff notify.
3379 Affected file irssi/src/silc/core/silc-servers.c.
3381 * Added the SilcClientFileError to be returned in the monitor
3382 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3383 Affected file lib/silcclient/silcapi.h.
3385 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Fixed a crash in silc_client_ftp_free_sessions and
3388 silc_client_ftp_session_free_client. Affected file
3389 lib/silcclient/client_ftp.c.
3391 * Added `disabled' field in the SilcChannelEntry in the server
3392 to indicate if the server entry is disabled. Affected file
3393 silcd/idlist.h, silcd/command[_reply].c.
3395 * SILC server adds now /var/run/silcd.pid everytime it is
3396 started. Affected file silcd/silcd.c.
3398 * Added silc_server_packet_send_clients to send a packet to
3399 the provided table of client entries. Affected file
3400 silcd/packet_send.[ch].
3402 * Fixed a crash in client resolving in client_prvmsg.c in
3403 client library. Affected file lib/silcclient/client_prvmsg.c.
3405 * Do not actually remove the client directly from ID cache
3406 during SERVER_SIGNOFF, but invalidate it. This way we
3407 preserve the WHOWAS info for the client. Affected file
3408 silcd/server_util.c.
3410 * Fixed SERVER_SIGNOFF notify handling in the server. The
3411 server is now able to process incoming SERVER_SIGNOFF notify
3412 for a server that it doesn't even know about. It will remove
3413 the clients provided in the notify. Affected file
3414 silcd/packet_receive.c.
3416 * Check for partial packet in data queue after every packet that
3417 was found from the queue. Return and wait for more data if
3418 there is partial data in queue. Affected file is
3419 lib/silccore/silcpacket.c.
3421 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Added SilcClietFileError enum to indicate error in
3424 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3425 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3426 Affected files lib/silcclient/silcapi.h and
3427 lib/silcclient/client_ftp.c.
3429 * Check that newsize in silc_buffer_realloc is larger than
3430 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3432 * Added better monitor of file transfers. It now monitors
3433 key agreement protocol during the file transfer too. Added
3434 error reporting too. Affected files
3435 irssi/src/silc/core/silc-servers.c,
3436 irssi/src/fe-common/silc/module-formats.[ch].
3438 * Wrote a help file for FILE command.
3440 * Added silc_rng_global_get_byte_fast to get not-so-secure
3441 random data as fast as possible. Random data is read from
3442 /dev/urandom if available and from the SILC RNG if not
3443 available. It is used in padding generation. Affected file
3444 lib/silccrypt/silcrng.[ch].
3446 * All packets in client library are now processed synchronously.
3447 Optimized packet processing a lot. Affected file
3448 lib/silcclient/client.c.
3450 * All server connection packets are processing synchronously
3451 now in server, to optimize packet processing. Affected file
3454 * Include files are installed now only in Toolkit distribution
3455 if make install is given. Affected files: all Makefile.am's.
3457 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Assure that silc_client_notify_by_server_resolve does not
3460 resolve the client information multiple times. If it cannot
3461 be found by the first it cannot be found at all. Affected
3462 file lib/silcclient/client_notify.c.
3464 * Fixed WHOWAS command reply calling. Affected file
3465 lib/silcclient/command_reply.c.
3467 * Removed all references to silc_idlist_get_client from the
3468 Irssi SILC client since that call is internal call used by
3469 the library. The Irssi SILC client will use now client
3470 retrieval functions found in silcapi.h.
3472 * Fixed a bug in resolving nickname info before sending
3473 private message. It used freed memory. Affected file
3474 irssi/src/silc/core/silc-servers.c.
3476 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Assure my_channels statistics cannot go negative in server.
3479 Affected files silcd/server.c, silcd/server_util.c.
3481 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3483 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3485 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Win32 Toolkit changes. Affected files
3488 win32/silc.dsw, win32/libsilc/libsilc.def,
3489 win32/libsilcclient/libsilc.def,
3490 lib/silcutil/silcutil.c, and
3491 lib/sftp/sftp_fs_memory.c.
3493 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3495 * Added silc_net_localip to return local host's IP address.
3496 Affected file lib/silcutil/silcnet.[ch].
3498 * If key exchange or rekey protocol is active for a connection
3499 parse all packets syncronously since there might be packets
3500 in packet queue that we are not able to process without first
3501 processing packets before them. Affected file silcd/server,
3502 lib/silcclient/client.c.
3504 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3505 whether library should continue processing the packet.
3506 Affected file lib/silccore/silcpacket.h.
3508 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3509 SilcSFTPMonitorData to SFTP server to monitor various
3510 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
3511 lib/silcsftp/sftp_server.c.
3513 * Added silc_file_size to return file size. Affected file
3514 lib/silcutil/silcutil.[ch].
3516 * Implemented the file transfer support for the client library.
3517 Added preliminary support for simple client to client one-file
3518 transmission. Affected file lib/silcclient/client_ftp.c,
3519 lib/silccilent/client.[ch].
3521 * Added new local command FILE to the Irssi SILC Client.
3522 It is used to perform the file transfer. It has subcommands
3523 SEND, RECEIVE, SHOW and CLOSE. Affected files
3524 irssi/src/silc/core/client_ops.c,
3525 irssi/src/silc/core/silc-server.[ch].

3534 * Renamed silc_file_read and silc_file_write to functions
3535 silc_file_readfile and silc_file_writefile. Added function
3536 silc_file_open and silc_file_close. Affected files
3537 lib/silcutil/silcutil.[ch].
3539 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Resolve the client info when received private message or
3542 channel message for a client which nickname we don't know.
3543 Affected files lib/silcclient/client_prvmsg.c and
3544 lib/silcclient/client_channel.c.
3546 * Do not crash in /KEY if client is not connected. Affected
3547 file irssi/src/silc/core/silc-channels.c.
3549 * Added SilcClientStatus field to the SilcClientEntry in the
3550 lib/silcclient/idlist.h.
3552 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3553 is incomplete and is being resolved, it won't be resolved
3556 Make sure also that USERS command reply does not resolve
3557 twice information. Affected file is
3558 lib/silcclient/command_reply.c.
3560 Make sure that silc_client_get_clients_by_list does not
3561 resolve twice same information.
3563 * Check for valid client->id in the silc_server_free_client_data.
3564 Affected file silcd/server.c.
3566 * Fixed /GETKEY nick@server not to crash if the server entry
3567 is not found. Affected file lib/silcclient/command.c.
3569 * Fixed the silc_server_check_cmode_rights to check the
3570 requested modes correctly. Affected file silcd/command.c.
3572 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Better checks for non-printable chars in nick added.
3575 Affected file silcd/command.c.
3577 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Call the silc_server_udpate_servers_by_server in the
3580 primary router that comes back online in the backup resuming
3581 protocol. Otherwise it routes packets wrong. Affected file
3582 silcd/server_util.[ch], silcd/server_backup.c.
3584 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3587 lib/silcutil/silcbuffmt.[ch].
3589 * Redefined the SILC packet header to include the padding
3590 length. Affected file lib/silccore/silcpacket.[ch].
3592 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3593 length for maximum padding up to 128 bytes). Affected
3594 file lib/silccore/silcpacket.h.
3596 * Removed all backwards support for old 0.5.x MAC thingies.
3597 The SILC packet header change makes it impossible to be
3598 backwards compatible.
3600 * Send the ENDING packet with timeout in the backup resuming
3601 protocol. This is to assure that all routers has connected
3602 to the primary router. Affected file silcd/server_backup.c.
3604 * Changed the RNG to take the first IV from random data. It
3605 used to take it from zero actually. Changed the RNG also
3606 to use /dev/urandom during session. /dev/random is used
3607 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3609 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3611 * Changed the SILC packet header to have the first two bytes
3612 (the packet length) encrypted. Affected files aroung the
3613 code tree, lib/silccore/silcpacket.[ch]. Removed the
3614 SilcPacketCheckDecrypt callback. It is not needed anymore
3615 since the silc_packet_receive_process will determine now
3616 whether the packet is normal or special.
3618 * Implemented the unidirectional MAC keys. Affected files
3619 lib/silcske/silcske.c, silcd/protocol.c and
3620 lib/silcclient/protocol.c.
3622 * Implemented the packet sequence number to the MAC computation.
3623 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3624 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3625 lib/silcclient/protocol.c.
3627 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Allow backup router to announce servers. All servers
3630 announced by backup router are added to the global list
3631 automatically. Update hte server's socket to our primary
3632 router also when backup router announces a server.
3633 Affected file silcd/packet_receive.c.
3635 * Do not update the client->router in the function
3636 silc_server_udpate_clients_by_server if the client is on
3637 global list. We might fail to find any specific server
3638 for locally connected clients and local cell clients. They
3639 should still use the `from' and not `to' as client->router.
3640 This fixes backup router resuming protocol. Affected file
3641 silcd/server_util.c.
3643 * Decrease channel statistics count only if the channel
3644 deletion worked. Affected files are silcd/server.c and
3645 silcd/server_util.c.
3647 * Added silc_server_update_servers_by_server to update origin
3648 of all server entries. Used during backup router protocol.
3649 Affected files silcd/server_util.[ch], silcd/server.c. and
3650 silcd/backup_router.c.
3652 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3653 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3654 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3655 lib/silccrypt/silchmac.c.
3657 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Assure that router cannot reroute the same channel message
3660 to the sender. Affected file silcd/packet_receive.c.
3662 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Made better checks that the channel message is not sent
3665 to the router it came from. Affected file is
3666 silcd/packet_send.c. Fixed memory leak too.
3668 * Announce informations for incoming router connection, but
3669 only after checking if it is replaced by backup router.
3670 Affected file silcd/packet_receive.c.
3672 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3674 * Fixed the backup resuming protocol to work in multiple
3675 router environment. Affected file silcd/server_backup.c.
3677 * Route packet only to one router in the function
3678 silc_server_packet_send_to_channel. Affected file is
3679 silcd/packet_send.c.
3681 * Fixed silc_server_send_notify_dest to set the broadcast
3682 flag. Fixed the silc_server_send_notify_topic to actually
3683 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3684 Affected file silcd/packet_send.c.
3686 * Changed the SFTP Filesystem interface. Changed the
3687 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3688 the filesystem operation function. The SilcSFTPFilesystem
3689 is now a context that is allocated by all filesystem allocation
3690 functions and it already includes the operations structure
3691 and filesystem specific context. It is given as argument
3692 now to the silc_sftp_server_start. This made the interface
3693 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3694 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3696 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3698 * Changed the backup router adding and getting interfaces
3699 in the server. The router that will be replaced by the
3700 specified backup router is now sent as argument. Affected
3701 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3704 * Added silc_net_addr2bin_ne to return the binary form of
3705 the IP address in network byte order. Affected files
3706 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3708 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3710 * Check for existing server ID in silc_server_new_server
3711 and in silc_server_connect_to_router_final and remove the
3712 old entry if it exists. Affected file silcd/packet_receive.c,
3715 * Send the channel message always to only one router, either
3716 in upstream or downstream. Affected file is
3717 silcd/packet_send.c.
3719 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3721 * Wrote the definition of the backup resuming protocol to the
3722 protocol specification.
3724 * Removed one redundant channel key generation from normal
3725 server during joining procedure. Removed one redundant
3726 channel key sending from server to router during joining
3727 procedure. Affected file silcd/command.c.
3729 * Made minor bugfixes to the backup router resuming protocol.
3730 Affected file silcd/server_backup.c, server.c.
3732 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3734 * Added --disable-asm configuration option. Affected files
3735 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3738 * Implemented the backup resuming protocol that is used to
3739 resume the primary router position in the cell after the
3740 primary router comes back online. Affected files
3741 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3742 and silcd/server_util.[ch].
3744 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Sleep two (2) seconds after sending QUIT command to server.
3747 Affected file lib/silcclient/command.c.
3749 * Assure that if outgoing data buffer is pending do not force
3750 send any data. Affected file silcd/packet_send.c.
3752 * Assure that if outgoing data buffer is pending do not force
3753 send any data. Affected file lib/silcclient/client.c.
3755 * Implemented the backup router support when the primary router
3756 goes down. The servers and routers can now use the backup
3757 router as new primary router without loosing connectivity.
3759 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3761 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3762 in the server to indicate disabled entry. All data read
3763 from the connection will be ignored and no data is sent
3764 for entry that is disabled. Affected files are
3765 silcd/idlist.h, silcd/server.c.
3767 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3769 * Created SFTP client and server test programs in the
3770 lib/silcsftp/tests directory.
3772 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3774 * Implemented memory filesystem (virtual filesystem) for
3775 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3778 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3780 * Implemented the SFTP (SSH File Transfer Protocol) to the
3781 lib/silcsftp. It includes SFTP client and SFTP server
3784 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3786 * Moved lib/silccore/silcprotocol.[ch] to the
3787 lib/silcutil library.
3789 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3790 take variable argument list pointer as argument. Affected
3791 file lib/silcutil/silcbuffmt.[ch].
3793 * Added silc_buffer_set function that is used to set data
3794 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3795 Affected file lib/silcutil/silcbuffer.h.
3797 * Changed various routines in the core library to use the new
3798 silc_buffer_set instead of allocating new buffer only for
3801 * Added 64-bit value formatting and unformatting support to the
3802 silc_buffer_[un]format routines. Affected file is
3803 lib/silcutil/silcbuffmt.[ch].
3805 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3806 to includes/bitmove.h.
3808 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Fixed channel user mode saving in client library. Affected
3811 file lib/silcclient/command[_reply].c.
3813 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Defined the file transfer to the SILC Protocol. Added
3816 new packet type SILC_PACKET_FTP and defined File Transfer
3817 Payload. The mandatory file transfer protocol is SFTP
3818 (SSH File Transfer Protocol). Affected file in addition
3819 of the internet draft is lib/silccore/silcpacket.h.
3821 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3822 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3823 is used as part of backup router protocol when the primary
3824 router of the cell is back online and wishes to resume
3825 the position as primary router.
3827 * Redefined the MAC generation keys in the protocol. The
3828 same key is not used anymore in both direction. Both
3829 direction will now use different keys for sending and
3830 receiving. This fixes a potential security flaw. This
3831 change causes incompatibilities in the protocol.
3833 * Redefined also the MAC computation from the packet.
3834 An packet sequence number is now added to the MAC
3835 computation. This prevents possible replay attacks against
3836 the protocol. This change too causes incompatibilities
3839 Added `sequence' field to the SilcPacketContext to hold
3840 the current sequence number for the packet.
3842 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3844 * Added `created' field to the SilcIDListData in the file
3845 silcd/idlist.h to indicate the time when the entry was
3848 * Added `created' field to the SilcChannelEntry too. Affected
3849 file silcd/idlist.h.
3851 * Added `creation_time' aguments to all the announcement functions
3852 in the server. If it is provided then only the entries that
3853 was created after the provided time frame are actually
3854 announced. Affected file silcd/server.[ch].
3856 * The protocol says that the Channel ID's IP address must be
3857 based on the router's IP address. Added check for this in
3858 the silc_server_new_channel when processing incoming New Channel
3859 Payload. Affected file silcd/packet_receive.c.
3861 * Print out the correct version with --version in SILC client.
3862 Affected file irssi/src/silc/core/silc-core.c.
3864 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3866 * Fixed WHOWAS command to check for completnes of the client
3867 entry always, not just when the command is coming from client.
3868 Affected file silcd/command.c.
3870 * Added new function silc_server_packet_queue_purge to purge the
3871 outgoing data queue to the network. After the function returns
3872 it is guaranteed that the outgoing packet queue is empty.
3873 Affected file silcd/packet_send.[ch].
3875 * Purge the outgoing packet queue in the rekey protocol's final
3876 callback to assure that all rekey packets go to the network
3877 before quitting the protocol. Affected file silcd/server.c.
3879 * Added silc_client_packet_queue_parse as similar function as
3880 in server to the client library. The affected file is
3881 lib/silcclient/client.c.
3883 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3885 * Splitted silcd/server.c and created silcd/server_util.[ch]
3886 for utility functions.
3888 * Added new socket flag SILC_SF_DISABLED to indicate that the
3889 connection is open but nothing can be sent to or received from
3890 the connection. Affected file lib/silcutil/silsockconn.[ch].
3891 The checking for disabled socket is checked in the low level
3892 silc_socket_write and silc_socket_read functions.
3894 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3896 * Allow only nicknames and channel names that fits into the
3897 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3899 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * When processing JOIN command reply in server check that if
3902 the channel exists in our global list we'll move it the local
3903 list. Affected file silcd/command_reply.c.
3905 * Fixed the check whether client is joined on the channel already
3906 in JOIN command. Affected file lib/silcclient/command.c.
3908 * Fixed the JOIN command reply to check whether the channel
3909 already exists. Affected file lib/silcclient/command_reply.c.
3911 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Added silc_ske_status_string to map the SKE error numbers
3914 to readable strings. The affected files are
3915 lib/silcske/silcske[_status].[ch].
3917 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Do not show the private channels on the WHOIS channel list
3920 as it is not allowed by the protocol. The affected file is
3923 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3925 * Assure that the packet length digged from the actual packet
3926 is something sensible in the silc_packet_decrypt_rest_special
3927 in lib/silccrypt/silcpacket.c.
3929 * Free and NULL the allocated pointer in silc_hmac_alloc if
3930 the HMAC allocation fails. The affected file is
3931 lib/silccrypt/silchmac.c.
3933 * Print the selected security properties to the log files in
3934 the server. Affected file silcd/protocol.c.
3936 * Add SKE's reference counter even if calling the completion
3937 callback manually. Otherwise it goes negative, although it
3938 does not cause any problems. The affected file is
3939 lib/silcske/silcske.c.
3941 * Remove the client entry with short timeout after giving the
3942 KILL command. Affected file lib/silcclient/command.c.
3944 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3945 case all found clients are already disconnected (WHOWAS would
3946 found them) in the server. Affected file silcd/command.c.
3948 * Update the last_receive (time of last data received) to be
3949 updated only when received private or channel message so that
3950 the idle time showed in WHOIS makes more sense.
3952 * Added boolean field `valid' in to the SilcClientEntry in the
3953 client library to indicate whether the entry is valid or not.
3954 This fixes the nickname change bug on channel when changing
3955 the nickname to be same than the old (like nick to Nick) the
3956 nickname formatter doesn't set the new nick anymore to Nick@host.
3957 Affected file lib/silcclient/idlist.[ch].
3959 * Now actually fixed the nickname changing on disconnection.
3960 Added new function silc_change_nick to the Irssi SILC Client.
3961 Affected file irssi/src/silc/core/client_ops.c,
3962 irssi/src/silc/core/silc-nicklist.[ch].
3964 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Check that the public key exists in the GETKEY command before
3967 trying to encode it. Affected file silcd/command.c.
3969 * Print some notifications on received public keys with GETKEY
3970 command in the Irssi SILC Client. Affected files are
3971 irssi/src/fe-common/silc/module-formats.[ch],
3972 irssi/src/silc/core/client_ops.c.
3974 * Use IDENTIFY command to resolve the server information in the
3975 GETKEY command instead of INFO command. Affected file
3976 lib/silcclient/command.c.
3978 * All command reply functions in the client library now calls
3979 the pending command reply callbacks even if an error has
3980 occurred. The server has done this a long time and now it was
3981 time to move the client library to this as well. Now all
3982 errors can be delivered back to the pending command reply
3983 callbacks if necessary. Affected files are
3984 lib/silcclient/command[_reply].[ch].
3986 * Change the nickname on disconnection back to the username
3987 because in reconnect the server will enforce it to it anyway.
3988 Affected file irssi/src/silc/core/silc-servers.c.
3990 * Fixed a config file parsing bug in the Irssi SILC client.
3991 Affected file irssi/src/silc/core/clientconfig.c.
3993 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3995 * When printing the channel mode on JOIN, verify that the
3996 channel key and channel's HMAC are valid. Affected file
3997 irssi/src/silc/core/client_ops.c.
3999 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4001 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4002 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4003 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4005 * Removed channel key rekey task deleting from the function
4006 silc_server_save_channel_key. Affected file silcd/server.c.
4007 Added explicit timeout task context instead that is used to
4008 delete the task if we are registering a new task before the
4009 new task has elapsed.
4011 * When channel key rekey occurs the client library now saves
4012 the old channel key for a short period of time (10 seconds) and
4013 is able to use it in case some is still sending channel
4014 messages encrypted with the old key after the rekey. Affected
4015 file lib/silcclient/[idlist.h|client_channel.c].
4017 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * Added check to the silc_server_new_id_real to not accept
4020 new ID if it is the sender's own ID. Affected file is
4021 silcd/packet_receive.c.
4023 * Assure that we do not announce ourself or the one we've
4024 sending our announcements when we're router and are announcing
4025 servers to our primary router. Affected file silcd/server.c.
4027 * Fixed silc_server_command_identify_check_client to assemble
4028 correct WHOIS packet. It send corrupted WHOIS packet and
4029 caused problem with router to router connections. Affected
4030 file silcd/command.c.
4032 Fixed also silc_server_command_whois_check the same way
4033 as for the IDENTIFY command.
4035 * Added new SilcIDListStatus to the server in the SilcIDListData
4036 structure. The status now includes the current status of
4037 the entry (like registered, resolved etc.). Affected file
4038 silcd/idlist.[ch]. Defined a bunch of different status types
4039 as well. This replaced the old boolean registered field as well.
4041 Added resolve_cmd_ident field to the SilcClientEntry structure
4042 too so that if the entry is for example being resolved so
4043 another command may attach to the same pending command reply
4044 without requiring to resolve the same entry again. This concept
4045 should optimize the WHOIS and the IDENTIFY resolving under
4046 heavy load by taking away unnecessary resolving for entries
4047 that are being resolved already.
4049 Added support for adding multiple pending commands for one
4050 command idenfier. Affected file silcd/command[_reply].[ch].
4052 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4053 before deleting the data. Otherwise the hash table will have
4054 freed data in comparison functions. Affected file is
4055 silcd/command_reply.c.
4057 * Fixed silc_idlist_replace_client_id to add the new entry to
4058 the cache with NULL nickname. Otherwise there will be invalid
4059 memory as the nickname after the nickname is freed. Affected
4060 file silcd/packet_receive.c.
4062 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4063 saved into wrong slots because the previous number of entries
4064 was not taken into account. Affected file silcd/idlist.c.
4065 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4067 * If we are router and we receive JOIN notify to a channel that
4068 does not have any users then notified client is marked as the
4069 channel founder, as it is it. The affected file is
4070 silcd/packet_receive.c
4072 * Added to the extended hash table API's table_del_*ext functions
4073 the destructor as argument too, so that the caller can decide
4074 which destructor to use or whether to use destructor at all.
4075 Affected file lib/silcutil/silchashtable.[ch].
4077 * Fixed ID Cache purging. It actually deleted the entries from
4078 the hash table after the data was freed. The hash table ended
4079 up comparing freed memory. The affected file is
4080 lib/silccore/silcidcache.c.
4082 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * Fixed Irssi SILC client's KILL command's HELP syntax.
4086 * The USERS command now resolves the detailed user information
4087 if the userinfo field is missing. Affected file is
4088 lib/silcclient/command_reply.c.
4090 * Do not print error in silc_file_read if the read file does
4091 not exist. Just silently return NULL. Affected file is
4092 lib/silcutil/silcutil.c.
4094 * Fixed the silc_log_output to not wine about NULL filename
4095 and to not create some bogus " " filename. Affected file is
4096 lib/silcutil/silclog.c.
4098 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4100 * Fixed various printing bugs on the user interface in the
4101 Irssi SILC Client. Minor changes that were forgotten from
4104 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4106 * Fixed the configure.in.pre and the compilation and distribution
4107 environment to support the new autoconf 2.52. That version is
4108 now required to compile the CVS trunk.
4110 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4112 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4113 to generally parse user@fqdn format strings. Affected file
4114 lib/silcutil/silcutil.c.
4116 * Added nickname_format and nickname_force_format fields to the
4117 SilcClientParams structure. The first one defines the format
4118 for the nicknames that the library will enforce if the receives
4119 multiple same nicknames. The second one is boolean value and
4120 can be used to force the library to always enforce the format
4121 to the nicknames regardles whether there are multiple nicknames
4122 or not. This configurable formatting was employed to flexibly
4123 support accessing multiple nicknames from the user interface.
4124 The userinterface can now set the nicknames to what ever format
4125 they prefer. Affected file lib/silcclient/silcapi.h.
4127 Added function silc_client_nickname_format to the file
4128 lib/silcclient/idlist.c. It performs the nickname formatting.
4130 Added new field `hostname´ to the SilcClientEntry context.
4131 It holds the hostname of the client. Affected file is
4132 lib/silcclient/idlist.h.
4134 * Irssi SILC Client sets the nicknames in nick@hostn format.
4135 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4136 irssi/src/silc/core/silc-core.c.
4138 The WHOIS printing now also shows both the real nickname and
4139 the formatted nickname so that user knows how to access the
4140 user if there are multiple same nicknames cached. Affected
4141 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4142 printing formatting too to take the hostname now as a separate
4143 argument. The Affected file is
4144 irssi/src/fe-common/silc/modules-formats.[ch].
4146 * Changed the silc_client_get_clients_local to accept the formatted
4147 nickname as argument. It accepts the real nickname too but the
4148 formatted nickname can be used to find the true entry from
4149 multiple entries. Affected file lib/silcclient/silcapi.h and
4150 lib/silcclient/idlist.c.
4152 * Added nickname_format_parse field to the SilcClientParams.
4153 It is a callback function provided by the application to parse
4154 the nickname out of the formatted nickname string. The library
4155 calls it to get the nickname from the formatted string. Since
4156 the application generally knows better the format of the nickname
4157 string it parses it instead of the library, even though library
4158 encodes the formatted string. If the callback function is not
4159 provided then the library will use the string as is. The
4160 affected file is lib/silcclient/silcapi.h.
4162 * All the nickname strings passed to the client library in
4163 commands are now expected to be formatted nickname strings.
4164 If the command does not support the formatted nickname string
4165 it will assume that the sent string is the actual nickname.
4166 Affected file lib/silcclient/command.c.
4168 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Added public key authentication support to OPER and SILCOPER
4171 commands in the client library. Affected file is
4172 lib/silcclient/command.c.
4174 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * Changed the get_auth_methdod client operation to be asynchronous.
4177 It can be async if the application resolves the authentication
4178 method from the server during the negotiation. Added new
4179 SilcGetAuthMeth completion callback that the application will
4180 call after resolving the authentication method.
4182 Added function silc_client_request_authentication_method that
4183 the application can use to resolve the authentication method
4184 from the server. Added also SilcConnectionAuthRequest callback
4185 that the library will call after the server has replied. The
4186 application can call this function if it does not know the
4187 current authentication method.
4189 Affected files are lib/silcclient/client.c and
4190 lib/silcclient/silcapi.h.
4192 * The Irssi SILC client now automatically resolves the authentication
4193 method incase any configuration information is not present (and
4194 currently there never is). The affected file is
4195 irssi/src/silc/core/client_ops.c.
4197 * Fixed public key authentication from the client library.
4198 Affected file lib/silcclient/protocol.c. Changed also the
4199 protocol specification about the public key authentication in
4200 the connection authentication protocol. The actual data to be
4201 signed is now computed with a hash function before signing.
4203 * Fixed the public key authentication from the server as well.
4204 Affected file silcd/protocol.c.
4206 * Removed the mlock()'s from the memory allocation routines.
4207 Affected file lib/silcutil/silcmemory.c. The ./configure does
4208 not check anymore for the mlock(). Affected file is
4211 * Fixed USERS command in server to allow the execution of the
4212 command for private and secret channels if the client sending
4213 the command is on the channel. Affected file silcd/command.c.
4215 * Fixed silc_client_get_clients_local to return the clients
4216 count correctly. It could return wrong value. Affected file
4217 lib/silcclient/idlist.c.
4219 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4221 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4222 types. The assembler optimizations seemed not to like 64-bit
4223 data types. The assmebler optimizations thus are now enabled
4224 also for BSD systems as opposed to only enable them for Linux.
4226 * Do not check for threads at all on BSD systems. Affected
4227 file configure.in.pre.
4229 * Removed -n and -h options from the Irssi SILC Client since
4230 they are not used in silc.
4232 * Fixed the prime generation to assure that the first digit
4233 of the generated random number is not zero since our conversion
4234 routines does not like number strings that starts with zero
4235 digit. If zero digit is seen the random number is regenerated.
4236 This caused some corrupted RSA keys when the zero first digit
4237 was met. Affected file lib/silcmath/silcprimegen.c.
4239 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4241 * Fixed WIN32 configuration in the ./configure script.
4242 Fixed to include xti.h on environments that has it.
4243 Patches by Carsten Ilchmann and andrew.
4245 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4247 * Changed the silc_id_create_client_id to be collision
4248 resistant. It is now assured that there cannot be created
4249 two same client ID's. I suspect that some weird bugs in
4250 the server were actually caused by duplicate Client IDs.
4251 Affected file silcd/serverid.[ch]. A router receiving
4252 new ID now also assures and informs the sending server
4253 if the ID caused collision.
4255 * Changed the silc_id_create_channel_id to also assure that
4256 there are no collisions.
4258 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Statement about ignoring the Mutual Authentication flag when
4261 performing rekey with PFS was a bit misleading. It is ignored
4262 if it was set in the initial negotiation, it cannot be even
4263 set in the rekey. Fixed in the ke-auth draft. Started the
4264 new versions of the protocol drafts in the doc/.
4266 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4268 * Fixed a bug in silc_client_command_identify_save when saving
4269 new channel information. The channel name was no duplicated
4270 and caused crash on exit. Affected file is
4271 lib/silcclient/command_reply.c.
4273 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4275 * Fixed the getkey command handling in the server. Send just
4276 empty OK reply to the sender if the key could not be fetched
4277 (but everything else was ok, like the key just was not available).
4278 Changed the public key parameter to optional in the protocol
4279 specs so that empty OK reply can be sent. Affected file
4282 Added a message to Irssi SILC client to tell to user if the
4283 server did not return a public key.
4285 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4287 * Fixed a channel key regeneration bug. It registered new
4288 timeout tasks exponentially until all system resources were
4289 used. Affected file silcd/server.c.
4291 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4293 * Added the SILC Document generator to the scripts/silcdoc.
4294 It can be used to generate the Toolkit Reference Manual out
4295 of the source tree. Internally it will also use the RoboDoc
4296 generator now imported in util/robodoc.
4298 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4300 * Added couple of return's in rekey protocol if error orccurred
4301 during the protocol. The execution must be terminated.
4302 Affected file silcd/protocol.c. Also, terminate the protocol
4303 always with timeout.
4305 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4307 * The client's Client ID was created initally from the wrong
4308 nickname (it could have been in format nick@host) in the
4309 silc_server_new_client. Affected file silcd/packet_receive.c
4311 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4313 * Added some SILC_LOG_ERROR's to various error conditions
4314 if client could not be added to ID cache. Affected files
4315 silcd/packet_receive.c and silcd/server.c.
4317 * When client's sock->user_data is freed, NULL also the
4318 client->router and client->connection pointers. Added check
4319 for these pointers being NULL to various places around the
4320 code. Affected file silcd/server.c.
4322 * Added client->data.registered == TRUE checks to various
4323 places around the code to assure that unregistered client's
4324 are not handled when it is not allowed. Affected file
4327 * Added `bool registered' fields to all
4328 silc_idlist_[server|client]_get_* routines to indicate whether
4329 the fetched client needs to be registered or not. Affected
4330 file silcd/idlist.[ch].
4332 * Add your own entry as registered to the ID cache in the
4333 server. Affected file server.c.
4335 * Fixed a bug in silc_server_new_server. The SilcServer was
4336 set as the new server's context instead of SilcServerEntry.
4337 This naturally caused some weird bugs.
4339 * Added "updated" field the SilcChannelEntry which indicates
4340 the time since the channel entry was last accessed. This
4341 can be used to determine whether it is necessary to
4342 announce the channel after backup resuming protocol.
4343 Affected files silcd/idlist.[ch].
4345 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4347 * Do not delete the channel rekey task when adding it
4348 for in silc_server_create_channel_key.
4350 * Changed the silc_server_create_channel_key to return
4351 TRUE or FALSE to indicate the success of the channel key
4354 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Fixed MSVC++ project files and added missing files to
4357 Makefiles under win32/.
4359 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4361 * Do not add TCP_NODELAY flag if the operating system
4362 does not have it defined. Affected files are
4363 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4365 * Fixed buffer overflow from Irssi SILC Client. Affected
4366 file irssi/src/fe-common/core/themes.c.
4368 * Fixed double free in client library in the file
4369 lib/silcclient/client.c when disconnecting from server.
4371 * Applied double free patch from cras to Irssi SILC client.
4372 Affected files irssi/src/core/[modules/expandos].c
4374 * Fixed the disconnection handling to Irssi SILC Client.
4375 The application must call silc_client_close_connection
4376 in ops->connect client operation in case of failure of
4377 the connection. Affected file is
4378 irssi/src/silc/core/client_ops.c.
4380 * Do not set sock->protocol to NULL in the function
4381 silc_client_close_connection after executing the protocol's
4382 final callback since the sock might not be valid anymore.
4383 Affected file lib/silcclient/client.c.
4385 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4387 * Do not enable SILC_THREADS if the linking with libpthread
4388 did not happen. Affected file configure.in.pre.
4390 * Added notion to protocol specification that server must
4391 verify the sent authentication payload with CMODE when
4392 setting the channel founder key. Implemented it to the
4393 server. Affected file silcd/command.c.
4395 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4397 * Added _EXTRA_DIST SILC distribution variable to the
4398 distributions file. It is used to conditionally add extra
4399 files or directories to the specific distribution. Affected
4400 files ./prepare, Makefile.am.pre and distributions.
4402 Removed the `_' from the start of the distribution names.
4405 * Added README.WIN32 for instructions to compile the Toolkit
4408 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4410 * Fixed a double free in disconnection in the server. Affected
4411 file is silcd/server.c.
4413 * Fixed the lib/silcske/groups.c to work now also with GMP
4414 MP library. The string conversion did not work when using
4415 specific base and the base is indicated in the string as well.
4417 * Created win32/ directory which now includes MSVC++ specific
4418 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4419 It will appear only in the toolkit distribution
4421 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4423 * Changed the key material distribution function in case when
4424 the hash output is too short. The data is now concatenated
4425 a bit differently than it used to. Made the change to the
4426 SKE protocol specification.
4428 * Added better GMP detection to configure.in.pre. A patch
4431 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4433 * Fixed a minor bug in SKE that might cause some problem on
4434 some platforms. Affected file lib/silcske/silcske.c.
4436 * Added the cookie checking for initiator in the SKE. It checks
4437 that the responder returns the sent cookie unmodified. The
4438 affected file is lib/silcske/silcske.c. Added new SKE
4439 error type INVALID_COOKIE that can be sent during the
4440 negotiation. Fixed some memory leaks as well.
4442 * Added the "invalid cookie" error message to Irssi SILC client's
4445 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4447 * Added `task_max' field to the SilcClientParams to indicate
4448 the maximum tasks the scheduler can handle. If set to zero,
4449 default values are used. Affected file lib/silcclient/silcapi.h.
4451 * Fixed memory leaks in silc_client_close_connection. Affected
4452 file lib/silcclient/client.c.
4454 * Added silc_client_del_client_entry to client library to free
4455 all memory of given client entry. Affected file is
4456 lib/silcclient/idlist.[ch].
4458 * Added new functions silc_client_del_channel and
4459 silc_client_del_server to delete channel and server entries.
4460 Affected file lib/silcclient/[silcapi.h/idlist.c].
4462 * Removed silc_client_del_client_by_id from silcapi.h.
4464 * Fixed the INFO command to return the server's own info
4465 correctly when querying by Server ID. Affected file is
4468 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4470 * Removed the non-blocking settings in WIN32 code in the
4471 silc_sock_[read/write] and added SleepEx instead. Affected
4472 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4473 of input data is now checked with FIONREAD and ioctlsocket.
4475 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4477 * Call silc_schedule_task_del_by_context in the
4478 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4479 Affected file lib/silccore/silcprotocol.c.
4481 * Call silc_protocol_cancel for active protocols in the
4482 silc_server_close_connection if the funtion
4483 silc_server_free_sock_user_data has not been called.
4484 Affected file silcd/server.c.
4486 * Generic tasks cannot be deleted using the del_by_fd
4487 task deleting function since generic tasks does not match
4488 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4490 * Added a notion to SILCOPER help file that the SILCOPER works
4491 only on router server, not on normal server.
4493 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4495 * Added for WIN32 support for the new scheduler as well.
4496 Affected file lib/silcutil/win32/silcwin32schedule.c.
4498 * Fixed the SHA1 implementation to work on various platforms.
4500 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4502 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4503 API. It is part of the scheduler now. Everything else is
4504 as previously but some functions has changed their names.
4505 Checkout the lib/silcutil/silcschedule.h for the interface.
4506 Updated all applications to use the new interface. Affected
4507 files are lib/silcutil/silcschedule.[ch].
4509 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4511 * Found a bug in the SKE implementation. The HASH value,
4512 specified by the protocol, was not computed correctly. The
4513 public key of the responder was not added to the computation
4514 even though it is mandatory. Affected file lib/silcske/silcske.c.
4515 This unfortunately causes incompatibilities with older
4516 clients and servers.
4518 * Added WIN32 specific network init and uninit functions:
4519 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4520 the Winsock2. Affected file lib/silcutil/silcnet.h and
4521 lib/silcutil/win32/silcwin32net.c.
4523 * Set the socket always to nonblocking mode on WIN32 after
4524 reading data or writing data. Affected file is
4525 lib/silcutil/win32/silcwin32sockconn.c.
4527 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4529 * Fixed various compilation problems under WIN32. Affected
4530 files lib/silcutil/win32/silcwin32thread.c and
4531 lib/silcutil/win32/silcwin32schedule.c.
4533 * Removed all _internal.h #includes from public header
4534 files. Internal headers must never be included from
4537 Removed also the lib/silcske/payload_internal.h file.
4539 * All include files that may be needed (public and some others
4540 included by the public headers) by application developers are
4541 now copied to the ./includes directory. It does not copy any
4542 internal headers. Affected file Makefile.defines.pre and all
4543 Makefile.am's under lib/ and subdirs.
4545 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4547 * Do not change the ~/.silc directory's permissions automatically.
4548 Affected file irssi/src/silc/core/clientutil.c.
4550 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4552 * Do not cancel the protocol in silc_server_close_connection
4553 it might cause recursion. Now cancelled in the function
4554 silc_server_free_sock_user_data. Affected file silcd/server.c.
4556 * Fixed the silc_server_remove_clients_by_server to regenerate
4557 the channel keys correctly finally. Added also new function
4558 silc_server_remove_clients_channels to actually do it.
4559 Affected file silcd/server.c.
4561 * Fixed the silc_server_new_channel to not crash by giving
4562 wrong router to the new channel. Affected file is
4563 silcd/packet_receive.c.
4565 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4567 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4568 which is given as argument to the silc_client_alloc now.
4569 It can be used to configure the client and set various parameters
4570 that affect the function of the client.
4572 * The USERS command in server did not check whether the channel
4573 is private or secret. Affected file silcd/command.c.
4575 * Added new argument to the USERS command in protocol specification.
4576 The USERS command now can take the channel name as argument
4577 as well. Added support for this in client and server and
4578 updated the protocol specs.
4580 * Completed the GETKEY command in client. It can be now used
4581 to fetch also servers public key not only some clients.
4582 Affected files lib/silcclient/command[_reply].c.
4584 * Added silc_client_get_server to return server entry by the
4585 server name. Affected files lib/silcclient/silcapi.h and
4588 * Redefined the IDENTIFY command in protocol specification to be
4589 more generic. It now can be used to query information about
4590 any entity in the SILC Network, including clients, servers and
4591 channels. The query may be based either the entity's name
4592 or the ID. Added support for this in both client and server.
4594 Affected files silcd/command.c and lib/silcclient/command.c
4595 and command_reply.c.
4597 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4598 the _from_client and _from_server functions. Affected file
4601 * Added silc_client_get_channel_by_id_resolve to the file
4602 lib/silcclient/silcapi.h to resolve channel information by
4603 its ID. Added also silc_client_get_channel_by_id that
4604 does not resolve it from the server.
4606 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4608 * Added SilcServerEntry context into the client library
4609 to represent one server. The INFO command now allocates
4610 these to save the resolved server info. For now on the
4611 client library will also keep information about servers,
4612 connected and resolved with INFO.
4614 The INFO command now allocates the SilcServerEntry context
4615 and saves the server info there. The COMMAND_REPLY in
4616 the INFO now returns the parameters to application in
4617 same order as defined in the protocol specification.
4619 The entries are cached in the client->server_cache.
4621 * The INFO command is now issued after received the Client ID
4622 from the server. Affected file lib/silcclient/client.c.
4624 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4625 to the application as the mode changer might be server.
4626 It is guaranteed that NULL is not returned anymore to the
4627 application. Affected file lib/silcclient/client_notify.c.
4629 The ID Type is now also passed to the application so that
4630 it can check whether the returned entry is SilcClientEntry
4633 Added new function silc_client_get_server_by_id to return
4634 the server entry by ID. Affected files are the
4635 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4637 * Do not create the channel in the Irssi SILC Client when issuing
4638 the JOIN command but when received the sucessful JOIN command
4639 reply. Otherwise the channel might get created even though we
4640 could not join it. The Affected file is
4641 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4643 * Fixed a channel joining bug in router. The router must also
4644 check the channel modes, invite and ban lists etc. when serving
4645 the JOIN command sent by normal server. Affected file is
4646 silcd/command.c. The router now resolves the client's
4647 information from the server who sent the JOIN command if it
4648 does not know it, and processes the JOIN command only after
4651 * Changed the SilcCommandCb to take new argument; void *context2.
4652 Affected file lib/silccore/silccommand.h
4654 The second argument in the command callbacks in the server now
4655 includes the SilcServerCommandReplyContext if the command was
4656 called as pending command callback from the command reply.
4657 Otherwise it is NULL. When called as pending the status of the
4658 command reply will be checked and if it was erronous the
4659 error will be sent to the original sender of the command.
4660 This way the client always receives the error messages even
4661 though the server was actually the one who received the error
4662 when it resent the command to router, for example. Affected
4663 files silcd/command[_reply].[ch].
4665 * Fixed sending WHOWAS command's error message to client if
4666 the requested client could not be found. It was missing.
4669 * Changed the CMODE and CUMODE commands reply arguments in the
4670 protocol specification. The Channel ID is now sent in both
4671 of the commands to identify the channel. Implemented this
4672 new feature to the client and server. Affected files
4673 lib/silcclient/command_reply.c and silcd/command.c.
4675 * Made better checks for invite and ban lists in the JOIN
4676 command in server. Affected file silcd/command.c.
4678 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4680 * The server now performs the incoming host IP/DNS lookup
4681 using the silc_socket_host_lookup and thus does not block
4682 the server anymore. Affected file silcd/server.c.
4684 * Completed the multi-thread support for SILC Scheduler in
4685 the lib/silcutil/silcschedule.c.
4687 * Fixed the configure.in.pre to detect the pthread correctly
4690 * Fixed a deadlock in silc_task_queue_wakeup in the file
4691 lib/silcutil/silctask.c.
4693 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4695 * Added new function silc_schedule_wakeup that is used in
4696 multi-threaded environment to wakeup the main thread's
4697 schduler. It needs to be used when a thread adds a new task
4698 or removes a task from task queues. After waking up, the
4699 scheduler will detect the task queue changes. If threads
4700 support is not compiled in this function has no effect.
4701 Implemented the wakeup mechanism to both Unix and WIN32
4702 systems. Affected files are lib/silcutil/silcschedule.[ch],
4703 lib/silcutil/unix/silcunixschedule.c and the
4704 lib/silcutil/win32/silcwin32schedule.c.
4706 * Added new function silc_task_queue_wakeup to wakeup the
4707 scheduler by the specified task queue. Affected file
4708 lib/silcutil/silctask.[ch].
4710 * The silc_socket_host_lookup_start now wakes up the scheduler
4711 after adding the timeout task. Affected file is
4712 lib/silcutil/silcsockconn.c.
4714 * The silc_socket_host_lookup is synchronous now if the threads
4715 support is not compiled in. However, the callback is still
4716 called asyncronously through the scheduler, anyway. Affected
4717 file lib/silcutil/silcsockconn.c.
4719 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4721 * Added new function silc_socket_host_lookup to perform
4722 asynchronous IP and FQDN lookups for the socket connection.
4723 Affected files lib/silcutil/silcsockconn.[ch].
4725 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4727 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4728 that may or may not compile the mutex support in.
4730 Changed the silc_mutex_alloc interface. It allocates the
4731 mutex now to the sent pointer and returns TRUE or FALSE.
4733 Affected file lib/silcutil/silcmutex.h.
4735 * Wrote the SILC Task Queue interface to support multi-threads.
4736 Affected file lib/silcutil/silctask.[ch].
4738 * Wrote the SILC Scheduler to support multi-threads. Affected
4739 file lib/silcutil/silcschedule.c.
4741 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4743 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4744 in lib/silcutil/win32/.
4746 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4748 * Defined SILC Mutex API and SILC Thread API and implemented
4749 them for Unix. Affected files are
4750 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4751 lib/silcutil/unix/silcunixmutex.c and
4752 lib/silcutil/unix/silcunixthread.c.
4754 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4756 * Fixed the silc_server_remove_clients_by_server's channel
4757 key re-generation. The hash table handling was incorrect
4758 and would not work with many channels. Affected file is
4761 * Fixed some memory leaks around the server code.
4763 * Rewrote the silc_server_get_users_on_channel to support IPv6
4764 based Client ID's. Affected file silcd/server.c.
4766 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4767 specification. However, a separate document must be written
4768 to define the detailed signing procedure and the payload
4769 associated with the flag. Defined the flag to the
4770 lib/silccore/silcchannel.h as well.
4772 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4774 * Changed the dynamic tables to static size tables in the
4775 lib/silccrypt/silchmac.c.
4777 * Removed GCC dependencies from the code. A patch by cras.
4779 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4781 * Do not show the error "Error receiving packet bla bla"
4782 in server if it really was not an error (-2 means that reading
4783 is pending). Affected file silcd/server.c.
4785 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4787 * Fixed a possible crash in silc_server_remove_clients_by_server
4788 in silcd/server.c. Fixed there also some memory leaks.
4790 * Fixed the silc_idlist_replace_client_id. It could replace
4791 wrong key in the hash table. Affected file silcd/idlist.c.
4793 * Do not check whether there are global users on the channel
4794 if the channel->global_users is FALSE. Affected functions
4795 silc_server_remove_from_one_channel and
4796 silc_server_remove_from_channels in silcd/server.c. Also,
4797 do not check if the removed client is local as we can be
4798 sure that global client was not removed from the channel
4799 and checking for global users is not needed.
4801 * The silc_server_remove_clients_by_server now re-generates
4802 the channel keys correctly for those channels that had
4803 clients removed from them. Affected file silcd/server.c.
4805 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4807 * Found the reason of random crashes in the server. We weren't
4808 ignoring the SIGPIPE signal (which can be sent in write())
4809 and it crashed the server. Affected file silcd/silcd.c.
4811 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4813 * Assure that sock->user_data is not NULL in the function
4814 silc_server_packet_send in silcd/packet_send.c.
4816 * Disconnect the remote connection if it could not be added
4817 to any ID lists in the server. The affected file is
4820 * Check in silc_server_packet_send[_real/dest] that the
4821 socket is not disconnecting and ignore the data if it is.
4822 Affected file silcd/packet_send.c.
4824 * Define inline to __inline on native WIN32 compilation.
4825 Affected file includes/silcwin32.h.
4827 * Added some explicit type casts for inline code since MSVC
4828 require them. Affected files lib/silcutil/silcbuffer.h,
4829 lib/trq/silcdlist.h and lib/trq/silclist.h.
4831 * Print warning in log files from now on if the packet
4832 decryption fails. Affected file silcd/server.c.
4834 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4836 * Changed the `say' client operation's interface to accept
4837 new `type' argument to indicate the type of the message sent
4838 by the library. The application may filter the library's
4839 messages according the type. The affected file is the
4840 lib/silcclient/silcapi.h.
4842 * Added two new functions to lib/silcclient/silcapi.h:
4843 silc_client_del_client and silc_client_del_client_by_id.
4844 Affected file lib/silcclient/idlist.c.
4846 * Moved the clientincludes.h from includes/ to silc/ and
4847 serverincludes.h from includes/ to silcd/.
4849 * The modes for the CMODE and CUMODE are now passed as
4850 uint32 for application with COMMAND_REPLY. The affected
4851 file is lib/silcclient/command_reply.c.
4853 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4855 * /WHOIS without arguments shows client's own information.
4856 Affected file lib/silcclient/command.c.
4858 * Changed PING to not accept any arguments. The specs
4859 says that client can ping only the connected server so
4860 requiring an argument is not needed. Affected file is
4861 lib/silcclient/command.c.
4863 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4865 * Fixed a fatal bug in private message sending and reception
4866 encryption and decryption when using private message keys.
4867 The implementation was incorrect and did not follow the
4868 specification. It causd that some of the message were
4869 lost since it did not use the sending and receiving keys
4870 as the protocol suggests. This has been fixed and will cause
4871 incompatibilities with older clients when sending private
4872 message encrypted with private message keys. Affected files
4873 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4874 and various other in Irssi SILC Client.
4876 Added `responder' boolean argument to the functions
4877 silc_client_add_private_message_key[_ske] to indicate when
4878 the key is added as responder or initiator of the key
4881 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4883 * Removed the silc_ske_check_version function and created
4884 a SilcSKECheckVersion callback. Added also a function
4885 silc_ske_set_callbacks that is now used to set all SKE
4886 callbacks. The callback functions are not given to
4887 the SKE functions anymore, but this function is used to
4890 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4892 * Added `silc_version' argument to the silc_client_alloc
4893 to define the version of the application for the library.
4894 The library will use the version string to compare it
4895 against the remote host's (usually a server) version
4896 string. Affected file lib/silcclient/silcapi.h
4898 * Added the KE protocol context to Key Agreement context
4899 in client library so that we can abort the SKE if it
4900 is in process when we get timeout. Affected file is
4901 lib/silcclient/client_keyagr.c.
4903 * Do not resolve the client ID forever if it returns in the
4904 first time that such client does not exist. This was done
4905 for example with private message. Affected file is
4906 lib/silcclient/client_prvmsg.c.
4908 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4910 * Do not add regex.h for WIN32. The affected file
4911 includes/silcincludes.h.
4913 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4914 not work yet 100%. It generates the DLL's automatically
4915 when compiling with --with-win32 under cygwin.
4917 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4919 * lib/contrib/regex.c is not compiled on WIN32.
4921 * Added silc_net_get_socket_opt function to the
4922 lib/silcutil/silcnet.h.
4924 * Added includes/silcwin32.h for WIN32 specific includes
4927 * Do not use ptime structure or any of the posix process
4928 functions on WIN32 in lib/silccrypt/silrng.c.
4930 * Added silc_gettimeofday to provide generic function
4931 for struct timeval on all platforms. Added the function
4932 to lib/silcutil/silcutil.h.
4934 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4936 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4937 library as they clearly belong there. As a plus side we
4938 can make the actual socket connection routines platform
4941 Added also new generic function silc_socket_read and
4942 silc_socket_write (that used to be silc_packet_[read/write].
4943 The implementation of these are platform specific.
4945 * Added WIN32 specific routines of silc_socket_[read/write]
4946 to lib/silcutil/win32/silcwin32sockconn.c.
4948 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4950 * Added preliminary support for native WIN32 compilation under
4951 cygwin (using the -mno-cygwin option for GCC) to the
4952 ./configure.in.pre. The --with-win32 now prepares the
4953 compilation for native WIN32.
4955 * Rewrote the SILC Scheduler interface in the file
4956 lib/silcutil/silcschedule.h. The scheduler is now context
4957 based and does not have anymore any global static scheduler.
4958 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4959 and created lib/silcutil/win32 directory for WIN32 based
4962 * Added Unix specific network routines to the
4963 lib/silcutil/unix/silcunixnet.c and the old
4964 lib/silcutil/silcnet.c includes now only generic routines.
4966 Added WIN32 specific network routines to the
4967 lib/silcutil/win32/silcwin32net.c.
4969 * Added Unix specific utility functions from the
4970 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4972 * Added WIN32 SILC Scheduler to the file
4973 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4976 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4978 * Do not handle JOIN notify in the server if the target client
4979 is not registered (idata->registered == FALSE). The affected
4980 file is silcd/packet_receive.c.
4982 * Update the nickrec->founder in event_cumode in the Irssi SILC
4983 client. Affected file irssi/src/silc/core/silc-channels.c.
4985 * Fixed the CUMODE_CHANGE notify handling in the server when
4986 server and router are announcing their clients on channels.
4987 Now the mode changes are saved and notified correctly. The
4988 affected file is /silcd/packet_receive.c.
4990 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4991 They really did not replace the cache entry in the ID Cache.
4992 Now they do that. Affected file silcd/idlist.c.
4994 * Fixed the KICK notify handling in the Irssi SILC client to
4995 update the channel records so that the kicked client does not
4996 appear to be on the channel. The affected file is
4997 irssi/src/silc/core/silc-channels.c.
4999 * Always update the conn->current_channel when executing command
5000 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5002 * Fixed the KILL notify handling in Irssi SILC client to remove
5003 the killed client on all channels.
5005 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Fixed the silc_parse_command_line to remove extra spaces
5008 from the start and end of the arguments. Affected file is
5009 lib/silcutil/silcutil.c.
5011 * Cancel and free any active protocol in the function
5012 silc_server_close_connection. Affected file silcd/server.c.
5014 * Cancel and free any active protocol in the function
5015 silc_client_close_connction. Affected file is
5016 lib/silcclient/client.c.
5018 * Do not execute the KILL command for clients that are in
5019 history (ie. they are not in the network). Affected file is
5022 * Fixed KILL notify handling, client does not crash anymore.
5023 Affected file irssi/src/silc/core/silc-channels.c.
5025 * Reduced the default packet buffer size from 2048 to 1024 in
5026 lib/silccore/silcpacket.c.
5028 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5029 counter to the SKE context that is incresed when the SKE library
5030 performs async operation outside the library. If the outside
5031 process frees the SKE context and FREED status will be set
5032 and the library will detect after the sync operation that the
5033 libary is freed. The affected files are
5034 lib/silcske/silcske[_status].[ch].
5036 * Resolve the client entry information in the function
5037 silc_client_channel_message to assure that NULL pointer is not
5038 passed as client entry to the application. */
5040 * Fixed the task timeout calculation to assure that there is
5041 never negative timeouts. The affected file is
5042 lib/silcutil/silcschedule.c.
5044 * Fixed the channel user mode notification sending in server.
5045 It was sent point-to-point to the router (or to server by router)
5046 but it needs to be destined to a channel. The routines now
5047 supports sending the channel user mode notifys to the channels
5048 when announcing clients and channels. Affected files are
5049 silcd/server.c and silcd/packet_receive.c.
5051 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5052 It did not actually replace the old channel entry in the cache.
5053 Affected file lib/silcclient/client_notify.c.
5055 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Fixed a possible crash in silc_packet_send_prepare. It now
5058 assures always that there is enough space in the buffer and
5059 at the tail area of the buffer (for MAC).
5061 Fixed the inbound buffer reallocation in silc_packet_read.
5062 It was old code and did not handle the reallocation correctly.
5065 The affected file is lib/silccore/silcpacket.c.
5067 * Fixed buffer overflow in silc_parse_nickname in the file
5068 lib/silcutil/silcutil.c.
5070 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * make install generates new server keys only if there is not
5075 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5078 Added check that if the NOREPLY is set then we will not send
5079 the away message. This avoids infinite loop of away messages
5080 if both clients are away. The affected file is
5081 lib/silcclient/client_prvmsg.c.
5083 * Fixed client crash if /NICK was given without arguments.
5084 Affected file lib/silcclient/command.c.
5086 * Server does not send the invite list in INVITE command back
5087 to the client if the list was not altered. Added this notion
5088 to the protocol spec as well. Affected file silcd/command.c.
5090 Fixed possible crash in INVITE command by checking the
5091 value of silc_server_get_client_route command.
5093 * Fixed the INVITE notify type handling. The arguments are now
5094 taken in correct order and client does not crash. The affected
5095 file is irssi/src/silc/core/silc-channels.c.
5097 Removed the "Inviting xxx to channel" message from the
5098 client library away and let the application handle it.
5099 Affected file lib/silcclient/command.c. Added that message
5100 to Irssi SILC client's message formats.
5102 * Fixed CMODE command crash in client. It now checks the
5103 amount of arguments correctly and does not crash. The affected
5104 file is lib/silcclient/command.c.
5106 * Do not create new channel automatically in silc_channels_join
5107 but check whether the channel by that name already exists.
5108 Affected file irssi/silc/core/silc-channels.c.
5110 * Do not send the SERVER_SIGNOFF to router if the disconnected
5111 entity was the router. Affected file silcd/server.c.
5113 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5114 SILC client as it was missing from there.
5116 Added the handling of the KICK notify to the Irssi SILC client
5117 as it was missing. Added "you have been kicked" message to
5118 Irssi SILC client's message modules formats.
5120 Added the handing of the KILL notify to the Irssi SILC client
5121 as it was missing. Added the kill message module formats
5124 The affected file is irssi/src/silc/core/silc-channels.c.
5126 * The router did not save the channel mode the server announced.
5127 Affected file silcd/packet_receive.c.
5129 * Fixed a possible crash in INFO command in server. If the
5130 server did not provide the server info it crashed. Affected
5131 file silcd/command.c.
5133 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Fixed the GETKEY command in the server to check also the
5136 global list. Otherwise the GETKEY would not work correctly
5137 in normal SILC server. Affected file silcd/command.c.
5139 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Fixed GETKEY crash, it crashed if the command did not succseed.
5143 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5146 is now real and not just an macro interface to GMP.
5148 Removed the entire GMP from the source tree and imported new
5149 NSS MPI library instead. Reason for removing GMP is that it is
5150 extremely large and compiles extremely slow. The NSS MPI
5151 is only a few files and compiles in less than 10 seconds.
5152 The speed is also about the same as GMP. The MPI is imported
5153 to lib/silcmath/mpi.
5155 If the system has GMP installed we will still use the GMP.
5156 If it is not then the NSS MPI will be compiled.
5158 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Merged a long nickname (127 characters long) crash bugfix from
5161 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5163 * Merged a freed memory reference bugfix from Irssi CVS tree.
5164 Affected file irssi/src/core/commands.c.
5166 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Added the server's public key sving and verification to the
5169 server when performing the SKE. This was missing and the
5170 remote server's (or router's) public key was accepted without
5171 checking whether we have it previously or trust it at all.
5172 Affected file silcd/protocol.c.
5174 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Check in the silc_server_timeout_remote if protocol is active
5177 and make sure that the protocol's final callback is called so
5178 that all memory if freed. Affected file silcd/server.c.
5180 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * silc_server_whois_send_reply crashed the server if the nickname
5183 was 127 characters long. Affected file silcd/command.c.
5185 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5187 * Added sanity check to the silc_server_new_client. If the hostname
5188 is provided inside username then check that the provided hostname
5189 really is the same as the resolved one. If the hostname was not
5190 resolved then check it from the public key. Affected file is
5191 silcd/packet_receive.c.
5193 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5194 if the server disconnected us and the connection is not valid
5195 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5197 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5198 the library to the lib/silcutil/silcutil.[ch].
5200 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Close log file after open. Affected file
5203 lib/silcutil/silclog.c.
5205 * Check whether sock == NULL in silc_client_send_packet and return
5206 if it is. Affected file lib/silcclient/silcclient.c.
5208 * Check rec->entry == NULL in the Irssi SILC Client before
5209 sending the channel message. Affecte file is
5210 irssi/src/silc/core/silc-servers.c.
5212 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Merged a splitted window bugfix from Irssi CVS tree. The
5215 affected file is irssi/src/fe-text/textbuffer-view.c.
5217 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5218 It did not print nickname.
5220 * Improved the distributions system a bit.
5222 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5225 irssi/src/fe-text/gui-window.c.
5227 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5228 to in-active server. The affected file is
5229 irssi/src/silc/core/client_ops.c.
5231 * Resolve the client in USERS command reply if the entry does
5232 not have username resolved. The affected file is
5233 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5234 command to WHOIS command to really resolve stuff. The USERS
5235 is not used any more in any critical section so WHOIS can
5236 be used even though it might be slower than IDENTIFY.
5238 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5241 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Changed the protocol API a bit more consistent in the
5244 lib/silccore/silcprotocol.[ch].
5246 * Changed the following headers to ROBODoc format:
5248 lib/silccore/silcpayload.h
5249 lib/silccore/silcprotocol.h
5250 lib/silccore/silcsockconn.h
5252 All core library headers are now formatted.
5254 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Fixed a bug in Irssi SILC client; do not show that you are
5257 server/router operator if you really are not. Affected file is
5258 irssi/src/silc/core/client_ops.c.
5260 * Renamed silc_command_free_payload to silc_command_payload_free.
5261 Affected file lib/silccore/silccommand.h
5263 * Added silcmath.h to include the prototoypes of various routines
5264 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5267 * Changed the following headers to ROBODoc format:
5269 lib/silccore/silcchannel.h
5270 lib/silccore/silccommand.h
5271 lib/silccore/silcid.h
5272 lib/silccore/silcidcache.h
5273 lib/silccore/silcmode.h
5274 lib/silccore/silcnotify.h
5275 lib/silccore/silcpacket.h
5276 lib/silcmath/silcmath.h
5278 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added checking to the server code not to start the server if
5281 ciphers and stuff are not configured properly. Affected files
5282 silcd/serverconfig.[h] and silcd/server.c.
5284 * Changed the layout of the header files of the public interfaces
5285 in the SILC libraries. The new layout supports ROBODoc
5286 documentation tool (and some others) so that it is easy to create
5287 a library reference manual. All the other headers and source
5288 code must still follow the CodingStyle document. Also source
5289 code must not include these ROBODoc stuffs, only the headers.
5290 Furthermore, all public interface headers must now be named
5291 by using `silc' prefix, example: silcapi.h, silccipher.h.
5292 Some files were renamed due to this. All the other headers
5293 must not be used as public interfaces. I will update the
5294 CodingStyle document later. Changed following headers, so far:
5296 lib/silcclient/silcapi.h
5297 lib/silccore/silcauth.h
5298 lib/silccore/silcprivate.h
5299 lib/silccrypt/silcdh.h
5301 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Removed silc_client_packet_send_flush from the client library
5306 as it is not needed. Affected file lib/silcclient/client.[ch].
5308 * Added printing of message of unresolved authentication method
5309 to the Irssi SILC client. Added it to the module formats.
5310 Removed the same message from the client library.
5312 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Added new distribution feature, DISTLABEL. Every distribution
5315 can define own preprocessor label that can be used in the
5316 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5317 file distributions, acconfig.h.pre and prepare.
5319 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Added Makefile.defines_int to include the actual definitions
5322 for Makefile.defines.in. Tested the new distribution system,
5323 created distributions and tested installation.
5325 * Added AWAY message printing to the Irssi SILC client. Added
5326 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5328 * Added SCONNECT command to call the SILC's CONNECT command.
5329 Cannot use CONNECT directly since Irssi uses that internally.
5330 Affected file irssi/src/silc/core/silc-servers.c.
5332 Added ACTION local command. It is same as ME command but takes
5333 the channel as mandatory argument.
5335 Rewrote some of the Irssi's help files to suite for SILC
5338 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Added Makefile.defines[.in] that should for now on be included
5341 in all Makefile.am file in the source tree. That file includes
5342 all common compilation definitions for SILC source tree.
5344 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Minor changes to the ./prepare script to change the package
5347 name according the distribution name to the configure.in.
5349 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Created new distribution system. Added file `distributions'
5352 that defines all the distributions that can be created out of
5353 the SILC source tree. The ./prepare script now reads that
5354 file to determine how to prepare the distributions. The
5355 first argument to the ./prepare is the name of the distribution
5356 and second is the version of the distribution. If given
5357 without arguments it creates the default (toolkit) distribution
5358 with the default version (defined in ./prepare).
5360 All Makefile.am files that are subject to the distributions
5361 are now named as Makefile.am.pre. These are ./Makefile.am
5362 and lib/Makefile.am. Others may be changed later.
5364 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Added invite list, ban list, some key management and connection
5367 error message printing to module formats in the Irssi SILC client.
5369 * Added new silc_client_set_away_message to set the away message
5370 that is back to the person who sent private message. The
5371 affected file lib/silcclient/silcapi.h and the
5372 lib/silcclient/client_prvmsg.c.
5374 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Fixed the private message sending in the Irssi SILC client,
5377 added local command KEY to the Irssi SILC client.
5379 Added key management and key agreement message formats to the
5380 irssi/src/fe-common/silc/module-formats.[ch].
5382 Added USERS (alias WHO) printing, server/router operator
5383 indication and LIST command printing to the module formats.
5385 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Fixed channel joining notify handling, cumode notify handling
5388 from Irssi SILC client.
5390 * Added SILC specific module-formats to the Irssi SILC client so
5391 that SILC specific message hilighting, colors etc is possible.
5392 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5394 Added channel mode, channel user mode, actions, notices,
5395 whois and whowas printing to the the module-formats.c.
5397 * Fixed a bug in channel deletion in the server. The channel
5398 is not left to the cache even if the channel founder auth mode
5399 is set when there are no users anymore on the channel. Affected
5400 file silcd/server.c.
5402 * The silc_net_localhost now resolves the entire hostname including
5403 the domain name. Affected file lib/silcutil/silcnet.c.
5405 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Changed the ask_passphrase client operation to be ascynchronous.
5408 It has now a completion callback and a context that the
5409 application must call after it has got the passphrase from
5410 the user. Affected files lib/silcclient/silcapi.h,
5411 lib/silcclient/protocol.c, lib/silcclient/command.c and
5414 Added SilcAskPassphrase callback that the application calls
5415 to deliver the passphrase to the library.
5417 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5418 The public key verification and especially a certificate
5419 verification is asynchronous procedure.
5421 Added new SILC_SKE_STATUS_PENDING status to indicate the
5422 request is pending and a callback will be called to finalize
5425 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5426 indicate that remote end did not send its public key (or
5427 certificate), even though we require it. Added check for this
5428 condition in the SKE. This was a security bug, now fixed.
5430 Defined new SilcSKEVerifyCbCompletion callback that is called
5431 when the verification process is completed.
5433 The affected files lib/silcske/silcske_status.h and
5434 lib/silcske/silcske.[ch].
5436 * Changed the verify_public_key client operation to be async
5437 as well. Defined SilcVerifyPublicKey callback that is used to
5438 indicate the success of the public key verification process.
5440 Changed the server and client to use the new async client
5443 * Changed the Irssi SILC client's internal scheduler to be called
5444 twice as many times as it used to be. As a result the client
5445 should be a bit faster now. Affected file is
5446 irssi/src/silc/core/silc-core.c.
5448 * Added support to Irssi SILC client of asynchronous public key
5449 verification and passphrase inquiry. Affected file is
5450 irssi/src/silc/core/silc-core.c.
5452 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Do not say "You have left channel %s" in client library.
5455 Moved it to the application. Affected files are
5456 lib/silcclient/command.c and silc/client_ops.c.
5458 * Fixed silc_client_get_clients. Command context was not
5459 duplicated and was freed memory in the callback. Affected
5460 file lib/silcclient/idlist.c.
5462 * Do not say "you are now talking..." on JOIN command in the
5463 client library. The appliation must handle it.
5465 * Do not say ".. changed topic to" in command reply in the
5466 client libary. The application must handle it.
5468 * Fixed TOPIC command sending in the client library.
5470 * Fixed a memory leak in silc_client_command_free in the file
5471 lib/silcclient/command.c.
5473 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Imported a modified version of Irssi client to the source tree.
5476 The Irssi will be used to create a new client called
5477 Irssi SILC. Imported to irssi/.
5479 Added silc_core_init_finish function to the Irssi. Affected
5480 file irssi/configure.in.
5482 A lot changes in the Makefile.ams around the irssi tree.
5484 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Do not rehash if the new size is same as the old size of the
5487 hash table, in the silc_hash_table_rehash*. The affected file
5488 lib/silcutil/silchashtable.c.
5490 * Replaced hash_table_del_by_context calls from the server
5491 (when channel->user_list and client->channels) to the
5492 hash_table_del as it is sufficient and faster.
5494 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Added silc_hash_table_list, silc_hash_table_get and the
5497 SilcHashTableList structure to provide an alternative way to
5498 traverse the hash table. The affected files are
5499 lib/silcutil/silchashtable.[ch].
5501 * Changed the server's idlist routines to use the hash table
5502 routines to optimize the code.
5504 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Replaced the client entry's `channel' list and channel entry's
5507 `user_list' list to hash tables for optimized lookup. Changed
5508 the code to use the hash table interface around the code.
5509 Affected file lib/silcd/idlist.[ch].
5511 * Added `auto_rehash' boolean argument to the function
5512 silc_hash_table_alloc to indicate whether the hash table should
5513 auto-rehash when it thinks is appropriate time. It will
5514 increase the hash table size if the there is twice as much
5515 entries in the table than the size of the table, and will
5516 decrease the size if there are twice as less entries than
5517 the size of the table.
5519 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5523 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * silc_idcache_purge_by_context deletes the entry now by context
5526 as it is supposed to do. Affected file lib/silccore/idcache.c.
5528 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5529 client is not anymore valid (WHOWAS givens the info) and not
5530 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5532 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Removed the `data' and `data_len' arguments from the ID Cache
5535 interfaces and added `name' argument. ID Cache does not handle
5536 anymore the binary data only a names associated with given ID.
5538 * When hashing a Client ID with silc_hash_id the entire ID is
5539 not hashed anymore, instead only the hash of the Client ID is
5540 hashed. This way we can access the Client ID from the cache
5541 with Client ID but with the hash of the ID (which is a hash of
5542 the nickname) as well without any difference in performance.
5544 Added also silc_idcache_find_by_id_one_ext to do one on one
5545 searching when we have the actual ID. Added also function
5546 silc_hash_client_id_compare. The affected files are
5547 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5549 * When hashing the name associated with a ID it is always done
5550 in lowercase. This way we can access the cache without worrying
5551 about case-sensitivity, even though, for example nicknames are
5554 * Fixed a bug in server with channel message sending. It put
5555 wrong ID type as destination ID. The affected file
5556 silcd/packet_send.c.
5558 * silc_idcache_del_by_context now deletes from all hash tables
5559 by context. Affected file lib/silccore/idcache.c.
5561 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Changed the client library to use the new ID Cache interface.
5564 Changes around the source tree.
5566 * Added silc_hash_table_rehash_ext to rehash with specific
5567 hash function. Affected file lib/silcutil/silchashtable.[ch].
5569 * Added silc_hash_string_compare to compare two strings in the
5570 hash table. Affected file lib/silcutil/silcutil.[ch].
5572 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Added new function silc_idcache_del_by_context into the
5575 lib/silccore/idcache.[ch].
5577 * Changed the server's ID list routines to use the new ID Cache
5578 interface. Changes around the source tree.
5580 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Added silc_hash_table_del[_by_context]_ext functions in to the
5583 lib/silcutil/silchashtable.[ch].
5585 Removed silc_hash_table_find_all* routines and added new
5586 silc_hash_table_find_foreach to replace them.
5588 Added silc_hash_table_replace_ext function as extended
5589 replacing function. Separated the simple hash table interface
5590 from the extended hash table interface in the file
5591 lib/silcutil/silchashtable.h.
5593 * Fixed minor bugs and changed it to use some of the new
5594 hash table functions in lib/silccore/idcache.c
5596 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added new function silc_hash_table_find_all to return all keys
5599 in the hash table by the specified key. As the hash table is
5600 collision resistant it also makes it possible to have several
5601 duplicate keys in the hash table. This function may be used to
5602 find all of the keys from the hash.
5604 Added user_context arguments to the SilcHashFunction,
5605 SilcHashCompare and SilcHashDestructor to deliver user specified
5608 Added new fuctions silc_hash_table_find[_all]_ext to do
5609 extended lookup with specified hash and compare functions and
5610 specified user contexts.
5612 Added new function silc_hash_table_add_ext to add the key
5613 with specified hash function and user context.
5615 Added new function silc_hash_table_foreach to traverse all
5616 entrys in the hash table. Added SilcHashForeach callback
5619 Added new function silc_hash_table_del_by_context to delete
5620 the entry only if the context associated with the key matches.
5622 Affected files are lib/silcutil/silchashtable.[ch].
5624 * Removed silc_hash_[server/client/channel]_id and added just
5625 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5626 silc_hash_id_compare to compare two ID's using as the hash table
5627 comparison function. Added also silc_hash_data to hash
5628 binary data and silc_hash_data_compare to compare it.
5630 * Removed silc_idlist_find_client_by_hash as it is not needed
5631 anymore. Affected file silcd/idlist.[ch].
5633 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5634 to use internally the SilcHashTable. The new ID Cache is a lot
5635 faster than the old one. Some of the ID Cache interface was also
5636 rewritten and obsolete and stupid functions were removed.
5638 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Added entry_count field to the SilcHashTable to keep the number
5641 of the entries in the table. Implemented the function
5642 silc_hash_table_rehash. Added new function
5643 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5645 Fixed a minor bug in silc_hash_table_free.
5647 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5648 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5649 into the lib/silcutil/silcutil.[ch].
5651 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Implemented a collision resistant hash table into the
5654 lib/silcutil/silchashtable[ch]. See the header and the source
5655 for the SilcHashTable API.
5657 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Merged dotconf version 1.0.2 into lib/dotconf.
5661 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Do not compile anything in lib/silcsim/* if the SIM support
5664 is not enabled. The tree should now compile without problems
5667 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Compiled the SILC under cygwin. Compiled and tested briefly
5670 without problems. More tests needed. The SIMs didn't compile
5673 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5675 * Fixed possible crash in silc_get_username in the
5676 lib/silcutil/silcutil.c.
5678 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Fixed a va_arg in silc/client_ops.c.
5682 * Oops, RC5 routines were named AES and caused some problems
5683 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5685 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added new SilcIDIP structure into the lib/silccore/id.h and
5688 replaced the old `ip' fields from all SILC ID's to that type.
5689 This is a step towards IPv6 support.
5691 The silc_id_get_len takes now the ID as an extra argument.
5692 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5693 both IPv4 and IPv6 based ID's.
5695 The affected files are lib/silccore/id.[ch] and other files
5696 around the tree using these routines.
5698 * Removed the ID length arguments in server from various
5699 silc_server_send_notify_* routines -> they are not needed
5702 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Fixed memory leak in silc_encode_pem_file in the file
5705 lib/silcutil/silcutil.c.
5707 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Check minor version as well in the SKE. Affected files are
5710 silcd/protocol.c and lib/silcclient/protocol.c.
5712 * Added --identifier option to the server so that an identifier
5713 can be when creating the public key for the server. Affected
5714 file is silcd/silcd.c.
5716 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5717 lib/silccrypt/silcpkcs.c.
5719 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Register default ciphers and stuff when using -C option with
5722 the server. Affected file sildc/silcd.c.
5724 * Put back the servers public key filename format, it is better
5725 than the new one. For now, the client keys are saved with the
5726 new filename format. The affected file silc/client_ops.c.
5728 * Implemented the Cipher API for the rest of the ciphers that
5729 did not implement it or implemented it the wrong way.
5731 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Register default ciphers and stuff when using the -S option
5734 in the client. Affected file silc/silc.c. Same also when
5735 creating new key pair with -C option.
5737 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Fixed the silc_verify_public_key client operation function to
5740 save the public keys differently. The fingerprint is now
5741 used as filename and not the hostname. This way also the
5742 client keys are saved uniquely and not with hostnames. The
5743 affected file is silc/client_ops.c.
5745 * Trimmed the silc_hash_fingerprint function to remove extra
5746 whitespaces from the end of the fingerprint. The affected
5747 file is lib/silccrypt/silchash.c.
5751 * Added silc_cipher_register_default function to register all
5752 default ciphers. It can be used when configuration files
5753 does not exist and the application does not want any specific
5754 ciphers in any specific order.
5756 The SilcDList is now used as silc_cipher_list dynamically
5757 allocated cipher list. Removed the static list all together
5758 and now all ciphers must be allocated to the dynamic list.
5759 The silc_cipher_alloc routine was changed to check only the
5762 All silc_cipher_* routines that used to return int returns
5765 The affected files lib/silccrypt/silccrypt.[ch].
5767 * The same thing was done to silc_hash_* as for silc_cipher_*
5768 routines. Affected files lib/silccrypt/silchash.[ch].
5770 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5771 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5772 Added also silc_pkcs_[un]register[_default] functions.
5773 Removed the data_context from the PKCS API.
5775 * Added silc_hmac_register_default function to register default
5776 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5777 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5778 to unregister all hmacs at once.
5780 * Register the default ciphers, hash functions, PKCSs and HMACs
5781 if client's configuration file does not exist. The affected
5784 * The client did not load the hash functions from the SIM
5785 modules at all. Added support for this. Affected file is
5786 silc/clientconfig.c.
5788 * When decoding public key with silc_pkcs_public_key_decode, check
5789 the supported algorithm only if PKCS are registered. Affected
5790 file lib/silccrypt/silcpkcs.c. The same was done with the
5791 silc_pkcs_private_key_decode.
5793 * Fixed the SILC List routines to keep the list always in order.
5794 It used to change the list's order when traversing the list but
5795 not it preserves the order. Affected file lib/trq/silclist.h.
5797 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Added the client library to use the SilcSocketConnection's
5800 reference counter (by silc_socket_dup) to prevent the bug that
5801 the socket object may be freed underneath async operation.
5803 * The name resolv library checking fixes in the configure.in.pre.
5806 * Created new version of the protocol drafts for future
5807 development. The -03 drafts are the ones that will be changed
5808 in the trunk now and the -02 will remain as they are.
5810 * Send list of CUMODE notifys to the router when announcing
5811 the channel users to the router. Affected file silcd/server.c.
5812 If the router receiving channel founder CUMODE for a channel
5813 that already has channel founder it will send CUMODE notify
5814 to the sender to remove the channel founder rights from the
5815 announced client. Affected file silcd/packet_receive.c.
5817 * The CUMODE notify may now use Server ID as well as the entity
5818 who changes the mode. Updated protocool specs.
5820 * Updated INSTALL and README files.
5822 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * New web pages in the http://silc.pspt.fi. The pages was
5829 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Implemented the [DenyConnectin] config section in the server.
5832 Added silc_server_config_denied_conn to check whether incoming
5833 connection is denied. Affected file silcd/serverconfig.[ch].
5835 * Do not check the ports when checking the incoming configuration
5836 data if the port is 0, meaning any. Affected file is
5837 silcd/serverconfig.c.
5839 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Fixed buffer overflow in silc_string_compare in the file
5842 lib/silcutil/silcutil.c.
5844 * Fixed double free in silc_server_command_leave in the file
5847 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Fixed the version checking in the server. Affected file is
5852 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Fixed the configuration data fetching when accepting new
5855 connections in the server. Affected file silcd/server.c.
5857 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Added `sender_entry' argument to the function
5860 silc_server_packet_relay_to_channel so that we can check
5861 whether some destination actually belongs to the same route
5862 the sender belongs (ie, we must not resend the packet to the
5863 sender). Affected file silcd/packet_send.[ch].
5865 * Added `servername' field to the SilcClientEntry in the server
5866 to hold the name of the server where client is from. Affected
5867 file is silcd/idlist.h.
5869 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Moved the channel message encrypting in the router betwen
5872 router connections from silc_server_channel_message to the
5873 silc_server_packet_relay_to_channel since we want to check
5874 whether we have anybody channel before encrypting anything.
5875 Affected files silcd/packet_[receive/send].c.
5877 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Fixed the [AdminConnection] server config section to support
5880 multiple entries. Affected file silcd/serverconfig.c.
5882 * Added support into the server to check the validity of the
5883 incoming connection before executing any KE or authentication
5886 * The connection configuration is now saved to the KE and
5887 connection auth protocol contexts and not fetched anymore in
5888 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5890 * The local hosts listenning address and port is also resolved
5891 now when starting the server. We want to have the socket object
5892 to include the real address and port for the listener. Added
5893 new function silc_net_check_local_by_sock into the files
5894 lib/silcutil/silcnet.[ch].
5896 * Fixed a broadcast bug in server -> do not broadcast if we
5899 * Fixed a routing bug. Do not route broadcast packets ever.
5900 Broadcast packets must be processed always and not routed since
5901 they may be destined to some other host than yourself and thus
5902 would get routed without no good reason. Affected file is
5905 * Added function silc_server_config_is_primary_route to check
5906 whether primary router connection has been configured (a router
5907 configuration that we are initiating). If there is not, we
5908 will assume that there is only two routers in the SILC network
5909 and we will use the incoming router connection as our primary
5910 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5912 * Changed the order of the broadcasting. Broadcast _after_ the
5913 packet has been processed not before. Affected file is
5916 * Fixed a [ClientConnection] parsing bug. The port was never
5917 parsed correctly thus resulting to port 0. Affected file
5918 silcd/serverconfig.c.
5920 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5921 argument and did not set the broadcast packet flag. Affected
5922 file silcd/packet_send.c. Fixed same bug in the function
5923 silc_server_send_notify as well.
5925 * If we receive NEW_ID packet for our own ID in the server, ignore
5928 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Removed the nickname from the Private Message Payload.
5933 Updated the code and the protocol specs.
5935 * Updated protocol specs for submitting to the IETF.
5937 * Tweaked the Random Number Generator a bit. Affected file
5938 lib/silccrypt/silcrng.c. Exported a new function
5939 silc_rng_[global]_add_noise which can be used to add more
5942 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Do not parse packets with different timeout when protocol
5945 is active -> may cause problem with rekey. Affected file
5948 * When server receives signoff notify it must not create
5949 new channel key if the client is on any channels since the
5950 sender of the signoff notify will create it.
5952 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added printing of error messages during SKE protocol from the
5955 failure packet sent by server during SKE. Affected file
5958 * Removed the client's failure_callback handling with timeout
5959 and handle it immediately when received.
5961 * The SKE library returned wrong type in SUCCESS and FAILURE
5962 packets. They must be 32 bit MSB not 16 bit MSB.
5964 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Ok, rewrote the logic of the re-key and now it seems to work.
5967 I tested it on high traffic with frequent re-keys without
5968 problems. Added hmac_receive (and renamed hmac to hmac_send)
5969 in SilcClientConnection in lib/silcclient/client.h and
5970 in SilcIDListData in silcd/idlist.h. Also, removed the
5971 SilcPacketParserContext's cipher and hmac fields as they are
5972 not needed anymore and actually caused some problems when
5973 the ciphers and hmac's changed underneath the packet parser.
5975 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * If re-key protocol is active then process the incoming packets
5978 synchronously since we must assure that icoming packets encrypted
5979 with the old key is processed before the new keys is set to
5980 use. This is true other packets than for REKEY packets.
5981 Affected file silcd/server.c. The same was done to client library
5982 as well, affected file lib/silcclient/client.c.
5984 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Fixed bug in client and server to accept the force send if
5987 the packet is send from silc_[server/client]_packet_process
5988 function. Otherwise the packets are never delivered, oops.
5990 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Disable force sending of packets when REKEY protocol is active.
5993 We must assure that no packet is sent directly when rekey is
5994 performed. All packets must be sent through packet queue.
5995 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5996 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5997 function is silc_[server/client]_packet_send_real to check
6000 * Replaced the SIM paths from example config files to
6001 /usr/local/modules. Also, make install creates now
6002 /usr/local/silc/logs directory to hold all the SILC server
6005 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Made the configure.in.pre work on Solaris. Patch by salo.
6009 * Made all ciphers compatible with non-x86 machines. Defined
6010 CBC mode macros into lib/silccrypt/ciphers_def.h.
6012 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Fixed the make install.
6016 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * When MAC computation fails the silc_packet_decrypt returned 0
6019 even though it was supposed to return -1. Fixed this. The
6020 affected file is lib/silccore/silcpacket.c.
6022 * Do not replace the config files in /etc/silc (in make install)
6023 if they already exist. Affected file ./Makefile.am.
6025 * Do not send re-key packets immediately but through packet queue.
6026 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6028 * Changed silc_net_check_host_by_sock to return FALSE if the
6029 IP/DNS could not be resolved. Though, it returns the IP address
6030 now even if it could not resolve it (but returns also FALSE).
6031 Affected file lib/silcutil/silcnet.[ch].
6033 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added silc_pkcs_decode_identifier to decode the public key's
6036 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6037 Added also silc_pkcs_free_identifier. Added also new context
6038 SilcPublicKeyIdentifier.
6040 * Added -S option to the silc client. It is used to dump the
6041 contents of the specified public key file.
6043 * Changed the PKCS api to return the public key length when
6044 setting the public key.
6046 * Fixed a fatal bug in the public and private key file loading.
6047 Affected file lib/silccrypt/silcpkcs.c.
6049 * Execute the packet parsing for client with zero (0) timeout
6050 if the protocol is active. Affected file silcd/server.c.
6052 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Made the key generation options to the silcd program. Added
6055 -C option, equivalent to client's option.
6057 * Added new [ServerKeys] config section to the server. It
6058 configures the server's public and private key.
6060 * Defined generic Public Key Payload into the protocol
6061 specification to send specific type of public keys and
6064 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6065 public key or certificate.
6067 * Implemented the GETKEY command to the server and to the
6068 client library and on user interface.
6070 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6072 * Made preliminary `make install' work.
6074 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Added SilcServerRekey context into silcd/idlist.h.
6078 * Added the PFS support as defined in the specification to the
6079 SKE protocol. Affected files lib/silcske/*.c.
6081 * Added `ske_group' field to the SilcServerRekey context to hold
6082 the number of the SKE group that is used with PFS in re-key.
6083 Affected file silcd/idlist.h.
6085 * Added PFS re-key support to the server. Affected file is
6088 * Added silc_protocol_cancel to cancel execution of the next
6089 state of the protocol. Affected file is
6090 lib/silccore/silcprotocol.[ch].
6092 * Added the re-key support with and without PFS to the client
6093 library. Re-key is performed once in an hour, by default.
6095 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6096 Added silc_client_rekey_callback and silc_client_rekey_final.
6097 Affected files are lib/silcclient/protocol.[ch] and
6098 lib/silcclient/client.[ch].
6100 * Removed the `hmac_key' and `hmac_key_len' fields from the
6101 SilcClientConnection structure; not needed. Affected file is
6102 lib/silcclient/client.h.
6106 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6108 * Do not ask whether user wants to use the negotiated private key
6109 for private messages, just use it. Affected file is
6110 silc/local_command.c.
6112 * Added `send_enc_key' and `enc_key_len' fields to the
6113 SilcIDListData structure since they are needed in the re-key
6114 phase. Affected file is silcd/idlist.[ch].
6116 * Implemented the simple re-key protocol into the server.
6117 Affected files silcd/server.c and silcd/protocol.[ch]. The
6118 re-key will be performed once in an hour, by default.
6120 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6121 Added silc_server_rekey, silc_server_rekey_callback and
6122 silc_server_rekey_final.
6124 * Removed Tunneled flag from the protocol. Updated the code
6125 and the specifications.
6127 * Adde `pfs' field to the SilcIDListData to indicate whether
6128 the PFS is to be performed in the re-key. Affected file is
6131 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6133 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6134 int64 of at least the xintXX size. If void * is less that 4
6135 bytes uint32 * will be used. Defined bool as boolean.
6137 * Changed _ALL_ unsigned long and unsigned int to uint32,
6138 unsgined short to uint16 in the source tree.
6140 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6141 not handle clients that has entry->data.registered == FALSE.
6142 They are not in the network anymore. Affected file is
6145 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Implemented the sending of the SERVER_SIGNOFF notify in the
6148 server. Affected file is silcd/server.c.
6150 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6151 Added also silc_notify_payload_encode_args into the
6152 lib/silccore/silcnotify.[ch].
6154 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6155 Affected file silcd/packet_receive.c.
6157 * Implemented the SERVER_SIGNOFF notify handling in the client
6158 library. Affected file lib/silcclient/client_notify.c. Also,
6159 implemnted the printing of the SERVER_SIGNOFF info to the
6160 application. Affected file silc/client_ops.c.
6162 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6163 if the deleting was successful. Affected file silcd/idlist.[ch].
6165 * Added support for public key authentication in the connection
6166 authentication protocol in the client library. Affected file
6167 lib/silcclient/protocol.c.
6169 * Changed the server's silc_idlist_get_clients_by_* interface
6170 to support already allocated array so that new entries may be
6171 added to pre-allocated array. Affected file silcd/idlist.[ch].
6172 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6173 and command replies.
6175 * All command reply functions in the server now calls the
6176 pending command callback even if error occured. This way the
6177 error will be delivered to the client as well. Affected files
6178 silcd/command.c and silcd/command_reply.c.
6180 * Fixed INFO command to return local server's info if no server
6181 was provided. Affected file lib/silcclient/command.c.
6183 * Removed RESTART command for good. Updated the code and the
6186 * Rewrote parts of the task system. It is a bit simpler now.
6187 Removed unsued task priorities. The affected files are
6188 lib/silcutil/silctask.[ch].
6190 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Moved the USERS printing from the library to the application.
6193 Affected files lib/silcclient/command.c and silc/client_ops.c.
6195 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Added channel key re-key support. The re-key is perfomed
6200 only by the router and is done once in an hour. Added `rekey'
6201 field to the SilcChannelEntry in the server. Affected files
6202 silcd/server.c and silcd/idlist.h.
6204 * Added silc_task_unregister_by_context into the file
6205 lib/silcutil/silctask.[ch].
6207 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Added SILC_UMODE_GONE mode to indicate when the client is not
6210 present in the SILC network. Added also support to the local
6211 command AWAY that will set this mode. Added support of showing
6212 "xxx is gone" in WHOIS command. The USERS command shows the
6213 gone status as well.
6215 * Fixed setting server and router operator privileges in the
6216 server's UMODE command. Affected file silcd/command.c.
6218 * Merged the SKE KE1 and KE2 payloads into one payload. The
6219 new KE payload is equivalent to the old KE2 payload.
6221 Cleaned up the SKE Start Payload parsing. It now uses the
6222 simple buffer unformatting to do the parsing. A lot faster
6225 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6226 to the SKE that is used to indicate whether both of the SKE
6227 parties should perform authentication. By default only the
6228 responder performs authentication. By setting this flag also
6229 the initiator must do authentication. By default it is unset
6230 since in normal SKE case, client to server connection, only
6231 the responder should do authentication. When doing SKE between
6232 two clients both should perform authentication. Updated the
6233 code and the protocol specs.
6235 * A little fix to IDENTIFY command in the server. Search the
6236 client first by hash not nickname. Affected file is
6239 * Fixed the silc_client_close_connection to support closing
6240 the client to client connections wihtout deleting too much
6241 data. Affected file lib/silcclient/client.c.
6243 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6244 are received if protocol used to be active but is not anymore
6245 the application would crash due to NULL pointer dereference.
6246 Affected files silcd/server.c and lib/silcclient/client.c.
6248 * Added `hash' field to the SilcClientConnection to include
6249 the hash function negotiated in the SKE protocol.
6251 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6252 to set the channel founder authentication data. A client can
6253 claim the founder rights later by providing the authentication
6254 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6255 This way the channel founder can regain the channel founder
6256 privileges even it is left the channel. This works only on
6257 local server and the client must be connected to the same
6258 server to be able to regain the founder rights. Updated the
6259 protocol specs accordingly.
6261 Added support to the CMODE command in the client to set the
6262 founder auth data. Read the README to see how to set it.
6264 Added support to the CUMODE command to claim the founder
6265 rights. Read the README to see how to do it.
6267 Added support for the founder authentication to the Channel
6268 Entry in the server. Affected file silcd/idlist.h.
6270 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6271 server's CMODE command. Affected file silcd/command.c.
6273 * Added the following new functions into lib/silccore/silcauth.[ch]:
6274 silc_auth_get_method and silc_auth_get_data.
6276 * The server now saves the remote hosts public key to the
6277 SilcIDListData pointer. Affected file silcd/protocol.c.
6279 * The normal server now does not remove the channel entry from
6280 the cache if the founder authentication data is set. It used
6281 to remove it if the founder was the last one on the channel on
6282 the server and left the channel. The auth data is saved and
6283 if the channel is re-joined later the old entry is used with
6284 the old auth data. Affected files silcd/command_reply.c and
6287 * Removed the `pkcs' field from the SilcIDListData structure
6288 in the server; it is not used. Affected file silcd/idlist.h.

6292 * Fixed packet processing on slow links. Partial packets were
6293 never re-processed because the incoming data buffer was cleared
6294 by the application. Application must not directly clear the
6295 sock->inbuf, the packet processing routines handle it. Fixed
6296 this in client library and in server.
6298 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Fixed the WHOIS and IDENTIFY send reply function to really
6301 check whether to send list or just one entry. Affected file
6304 * Cleaned up the LEAVE command's channel key distribution. The
6305 affected file silcd/command.c.
6307 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6308 can enforce the channel mode as well. In that case the ID
6309 includes the ID of the server. The code now enforces the
6310 mode change if the router have different mode than the server.
6312 * The notify client operation with CMODE_CHANGE notify can now
6313 return NULL client_entry pointer if the CMODE was not changed
6314 by client. Application must check for this.
6316 * Added <Server ID> argument to INFO command to support server
6317 info fetching by Server ID.
6319 * Added silc_server_announce_get_channel_users to get assembled
6320 packets of channel users of the specified channel. Affected
6321 file silcd/server.[ch].
6323 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6324 was freed underneath the ID Cache.
6326 * Re-announce clients when the server received CHANNEL_CHANGE
6327 notify from the router. Affected file silcd/packet_send.c.
6329 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6332 crashed since it did not handle the fact that there is no cipher
6333 called "3" and didn't check the error condition. Now fixed.
6335 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6336 flag. It can be used to send message requests.
6338 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Implemented the RESTART command in the client.
6342 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6343 notice type messages. Added notice printing to the user
6346 * The channel keys are not re-generated if the channel's mode
6347 is PRIVKEY, ie private key on the channel exists. Affected
6348 files silcd/server.c and silcd/command.c.
6350 * Fixed a little bug in channel message delivery when channel
6351 private keys are set in the server. Affected file is
6352 silcd/packet_send.c.
6354 * Changed the setting on channel->on_channel = TRUE from the
6355 silc_client_save_channel_key to the JOIN command reply. The
6356 key payload is not received if the private channel key is set.
6357 Affected file lib/silcclient/command_reply.c and the
6358 lib/silcclient/client_channel.c.
6360 * When the CMODE_CHANGE notify is sent and the channel private
6361 key mode is removed the channel key must be re-generated in
6362 other cells as well. Added this support for the router in the
6363 silcd/packet_receive.c.
6365 * Added new local command NOTICE to send notice message on
6366 channel. Affected file silc/local_command.[ch].
6368 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Added new local command ME to the client. It is used to send
6371 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6372 some action. Affected file silc/local_command.[ch].
6374 * Changed channel_message and private_message client operations
6375 to deliver the message flags to the application. Added also
6376 the `flags' arguments to the silc_client_send_channel_message
6377 and silc_client_send_private_message functions. Affected file
6380 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Redefined the Private Message Payload to support private message
6383 keys and to support the new private message flags. Updated
6384 the protocol specs. Flags makes it possible to have for example
6385 CTCP style messages.
6387 * Added new type SilcPrivateMessagePayload and defined an API
6388 for it in the lib/silcclient/silcprivate.[ch].
6390 * Tested private message private keys successfully. Tested the
6391 private message key set, unset and list commands with the new
6394 * Redefined the Channel Message Payload to include the channel
6395 message flags (equal with private message flags) to support
6396 for example CTCP style messages.
6398 * Defined some of the message (for channel and private message)
6399 flags. Updated the protocol specs and added the flags to the
6400 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6402 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Added SilcKeyAgreementStatus type to the key agreement routines
6405 to indicate the current status and error if one occured.
6406 The status types are defined in the lib/silcclient/silcapi.h.
6408 * Added new local command KEY that is used to set and unset private
6409 keys for channels, set and unset private keys for private messages
6410 with remote clients and to send key agreement requests and
6411 negotiate the key agreement protocol with remote client. The
6412 key agreement is supported only to negotiate private message keys,
6413 it currently cannot be used to negotiate private keys for channels,
6414 as it is not convenient for that purpose.
6416 * Fixed a minor pending callback setting bug in the function
6417 silc_client_get_client_by_id_resolve, now the function works.
6418 Affected file lib/silcclient/idlist.c.
6420 * Added function silc_net_get_local_port to get local bound
6421 port by socket. Added to lib/silcutil/silcnet.[ch].
6423 * Added `sockets' and `sockets_count' fields to the SilcClient
6424 object. They hold the sockets of the listenning sockets in
6425 the client. Listenning sockets may be for example the key
6426 agreement server. Affected file lib/silcclient/client.[ch].
6427 Added functions the silc_client_add_socket and the
6428 silc_client_del_socket. They are exported to the application
6431 * Added ~./silc/clientkeys to support other client's public keys.
6433 * Renamed verify_server_key client operation to verify_public_key
6434 and added one argument to indicate the type of the connection
6435 (server, client etc.).
6437 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Added silc_server_connection_auth_request to handle the
6440 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6441 silcd/packet_receive.[ch].
6443 * Added silc_server_send_connection_auth_request into the
6444 silcd/packet_send.c to send the connection auth request packet.
6446 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6449 * Fixed the public key authentication in responder side in the
6450 server. The `auth_data' pointer includes the SilcPublicKey
6451 not the path to the public key. Affected file silcd/protocol.c.
6453 * Implemented the public key authentication in the initiator side
6454 in the server. Affected file silcd/protocol.c.
6456 * Removed the [RedirectClient] config section from the server
6457 configuration. Is not needed and I don't want to implement it.
6459 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Cleaned up the CMODE command in the server. It now works
6462 correctly and supports all the modes defined in the protocol.
6463 Affected file is silcd/command.c.
6465 * Added `hmac_name' field to the SilcChannelEntry in the server
6466 to hold the default HMAC of the channel. It can be set when
6467 creating the channel (with JOIN command). Affected files
6470 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6471 type to indicate the change of the current cipher and hmac
6472 on the channel. Client can safely ignore the <cipher> argument
6473 (if it chooses to do so) since the CHANNEL_KEY packet will
6474 force the channel key change anyway. The <hmac> argument is
6475 important since the client is responsible of setting the new
6476 HMAC and the hmac key into use.
6478 * Fixed the CMODE command in the client library as well.
6480 * Tested CMODE command in router environment successfully.
6482 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Show the version of the remote client (or server) when connecting
6485 to the server. It is logged to the log file. Affected file
6486 is silcd/protocol.c.
6488 * Fixed the KILLED notify handling in the client library. The
6489 client must be removed from all channels when receiving the
6492 Also, do not remove the client entry when giving the KILL
6493 command but when the KILLED notify is received.
6495 * Removed silc_idlist_find_client_by_nickname from the server.
6496 Not needed anymore. Affected files silcd/idlist.[ch].
6498 * Implemented the CHANNEL_CHANGE notify type handling to the
6499 server. Affected file silcd/server.c.
6503 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added silc_server_send_notify_invite to send the INVITE
6506 notify between routers.
6508 * Implemented the INVITE command correctly to the server.
6510 * Implemented the INVITE notify type handling in the server.
6512 * Implemented the INVITE command to the client library and on the
6515 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Added function silc_server_get_client_resolve to find the
6518 client entry by ID from all ID lists and then resolve it
6519 (using WHOIS) if it cannot be found. Affected file is
6522 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * Implemented the BAN command to the client library.
6526 * The JOIN command in the server now checks the invite list
6529 * Changed the silc_command_reply_payload_encode_va and the
6530 silc_command_payload_encode_va to support that if argument is
6531 NULL it ignores and checks the next argument. Affected file
6532 lib/silccore/silccommand.c.
6534 * Added silc_server_send_notify_ban to send the BAN notify
6535 type between routers.
6537 * Chaned the silc_notify_payload_encode to support that if
6538 argument is NULL it ignores and checks the next argument.
6539 Affected file lib/silccore/silcnotify.c.
6541 * Tested ban lists in router environment successfully.
6543 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Implemented BAN command to the server, in silcd/command.[ch].
6547 * Removed the BAN and INVITE_LIST modes from the CMODE command
6550 * Added function silc_string_match to regex match two strings.
6551 Affected files lib/silcutil/silcutil.[ch].
6553 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Redefined parts of the SilcChannelEntry in the server to support
6556 the new ban and invite lists.
6558 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6560 * Redefined the INVITE command. The same command can be used to
6561 invite individuals to the channel but also to manage the invite
6562 list of the channel (to add to and remove from the invite list).
6563 Updated the protocol specs.
6565 * Added new command SILC_COMMAND_BAN that can be used to manage
6566 the ban list of the channel. Updated the protocol specs.
6568 * Removed the channel modes: the SILC_CMODE_BAN and the
6569 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6570 in the CMODE command. The equivalent features are now available
6571 using INVITE and BAN commands. Updated the protocol specs.
6573 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6574 in the network about change in the current ban list. The notify
6575 type is not used by the client.
6577 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6578 support the invite lists.
6580 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6582 * Added new function silc_string_regexify that converts string
6583 including wildcard characters into regex string that can
6584 be used by the GNU regex library. Added into the file
6585 lib/silcutil/silcutil.[ch].
6587 Added silc_string_regex_combine to combine to regex strings
6588 into one so that they can be used as one regex string by
6589 the GNU regex library. Added into the file
6590 lib/silcutil/silcutil.[ch].
6592 Added silc_string_regex_match to match two strings. It returns
6593 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6595 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Imported GNU regex to the soruce tree into lib/contrib.
6598 Fixed some compiler warning from the regex.c.
6600 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Fixed MOTD command in the server to work in router environment.
6604 * Fixed the MOTD command in the client library to support
6605 the server argument in the command.
6607 * Added `nickname_len' argument to the silc_idlist_add_client
6608 in the server, as the `nickname' argument may be binary data
6611 * Added silc_idlist_get_channels to return all channels from
6614 * Implemented LIST command to the server. Affected file is
6617 * Implemented the LIST command to the client library and on the
6620 * Added [<user count>] argument to the LIST command reply.
6621 With private channels the user count is not shown.
6623 * Updated TODO and README.
6625 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * The client entry's data.registered must be TRUE even with
6628 global client entry on global client list. The data.registered
6629 is used to check whether the client is anymore in the network,
6630 for example with WHOWAS command so it must be valid.
6632 * Fixed the WHOWAS command in the server. It now actually works
6633 in router environment. Added function into silcd/command_reply.c
6634 silc_server_command_reply_whowas_save.
6636 * Added silc_idlist_purge function to the silcd/idlist.c
6637 to periodically purge the ID Cache.
6639 * Fixed INFO command in the server. It works now in router
6640 environment. Added <server name> argument to the INFO command
6641 reply. Updated the protocol specs.
6643 * Fixed minor bug in silc_idcache_purge to not purge if the
6644 expire value is zero.
6646 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6647 they were buggy because of the WHOWAS information.
6649 * Fixed local command MSG to handle the async resolving of
6650 the remote client properly. It used to fail the first MSG.
6651 Affected file silc/local_command.c.
6653 * Added `data_len' field to SilcIDCache context.
6655 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6657 * Update TODO. Todo in commands in the server.
6659 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6662 used by routers as broadcast packet to inform other routers
6663 about the changed user mode.
6665 Implemented the notify handling in the server. Affected file is
6666 silcd/packet_receive.c. Added the function
6667 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6669 * Added new generic Channel Payload and deprecated the New Channel
6670 Payload. The New Channel Payload is now the generic Channel
6673 * Added new argument `mode' to the silc_server_send_new_channel
6674 as it is required in the Channel Payload now.
6676 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6677 and created a new and real SilChannelPayload to represent the
6678 new generic Channel Payload. Implemented the encode/decode
6679 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6681 * Added silc_server_get_client_channel_list to return the list
6682 of channels the client has joined for WHOIS command reply.
6683 Affected file silcd/server.[ch].
6685 * Implemented the channel list sending in the WHOIS command reply
6686 in server and in the client.
6688 Implemented the channel list displaying on the user interface
6689 as well. Affected file silc/client_ops.c.
6691 * Added silc_channel_payload_parse_list to parse list of Channel
6692 Payloads. It returns SilcDList list of SilcChannelPayloads.
6693 Client for example can use this function to parse the list of
6694 channels it receives in the WHOIS command reply. The caller
6695 must free the list by calling silc_channel_payload_list_free.
6696 Affected files lib/silccore/silcchannel.[ch].
6698 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Added one new argument <user mode> to the WHOIS command reply
6701 to return the mode of the user in SILC. Updated the protocol
6704 Implemented it to the server and client.
6706 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Fixed the mode printing on the user interface on joining.
6709 Affected file silc/client_ops.c.
6711 * Implemented the UMODE command and user modes in general to the
6712 client library and to the user interface.
6714 * Implemented the UMODE command to the server.
6716 * The server now sends UNKNOWN_COMMAND error status if client sends
6717 unknown command. Affected file silcd/command.c.
6719 * All server commands now handle the command identifier the right
6720 way when sending the command reply to the client. The client can
6721 use to identify the command replies with the identifier.
6723 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Added silc_server_get_client_route to resolve the route to
6726 the client indicated by the client ID. Affected file is
6729 * Added silc_server_relay_packet as general function to relay
6730 packet to arbitrary destination. This deprecates functions
6731 like _send_private_message_key, _relay_notify etc. Affected
6732 file is silcd/packet_send.[ch].
6734 Removed silc_server_send_key_agreement,
6735 silc_server_send_private_message_key and
6736 silc_server_packet_relay_notify functions from the file
6737 silcd/packet_send.[ch].
6741 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6742 server. Affected file silcd/packet_receive.[ch].
6744 * Implemented the KILL command to the client. Implemented the
6745 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6746 Affected files lib/silcclient/command[_reply].c and
6747 lib/silcclient/client_notify.c. Implemented the KILL notify
6748 printing in the user inteface.
6750 * Fixed a lot silc_parse_nick memory leaks from the client
6751 library in the file lib/silcclient/command.c.
6753 * Changed the silc_server_send_notify_on_channels's `sender'
6754 argument from SilcSocketConnection to SilcClientEntry to
6755 check the sender as entry and not as connection object and not
6756 to send to the client provided as argument. The affected file
6757 is silcd/packet_send.[ch].
6759 * The notify packets that are destined directly to the client used
6760 to not to be processed by the server. Now changed that and the
6761 server processes all notify packets. After relaying the packet
6762 to the client the notify packet is processed in the server.
6764 * The silc_server_free_client_data now checks whether there is
6765 pending outgoing traffic for the client and purges the data to
6766 the network before removing the client entry.
6768 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6771 an client is killed from the SILC Network. Updated the protocol
6774 Added new function silc_server_send_notify_killed to the
6775 silcd/packet_send.[ch].
6777 * Added function silc_server_packet_relay_notify to relay notify
6778 packets that are destined directly to a client. In this case
6779 the server does not process the notify packets but merely relays
6780 it to the client. Affected file silcd/packet_send.[ch].
6782 Added also silc_server_packet_process_relay_notify to check
6783 whereto relay the notify. Affected file is
6784 silcd/packet_receive.[ch].
6786 * Implemented the KILL command to the server.
6790 * Added the backup schema desgined last fall to the protocol
6791 specs for everyone to see. The specification is in the
6792 *-spec-xx.txt draft and the packet type definitions for the
6793 backup routers is in *-pp-xx.txt draft. Thusly, added also
6794 new packet type SILC_PACKET_CELL_ROUTERS.
6796 * A big security problem in the implementation discovered. The
6797 signoff of an client did not cause new channel key generation
6798 which it of course should've done. The channel keys must be
6799 always re-generated when client leaves (or signoffs) the channel.
6800 The silc_server_remove_from_channels funtion now handles
6801 the channel key re-generation.
6803 * Added `sender' argument to the silc_server_send_notify_on_channels
6804 to not to send the client provided as argument. Affected file
6805 silcd/packet_send.[ch].
6807 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Implemented OPER and SILCOPER commands into the server and
6812 * Added silc_auth_verify and silc_auth_verify_data to verify
6813 the authentication directly from the authentication payload.
6814 It supports verifying both passphrase and public key based
6815 authentication. Affected file lib/silccore/silcauth.[ch].
6817 * Added `hash' field to the SilcIDListData structure. It is the
6818 hash negotiated in the SKE protocol. Affected file is
6821 * Slight redesigning of the SilcAuthPayload handling routines.
6822 Do not send SilcPKCS but SilcPublicKey as argument.
6824 * Implemented the public key authentication support to the
6825 serverconfig. The public key is loaded from the provided path
6826 and saved as authentication data to void * pointer. Thus,
6827 changed the unsigned char *auth_data to void *auth_data;
6829 * Fixed SHUTDOWN command to send the reply before the server
6830 is shutdown. :) Affected file silcd/command.c.
6832 * Fixed fatal bug in CONNECT command. The hostname was invalid
6833 memory and server crashed. Affected file silcd/command.c.
6835 * Fixed fatal bug in CLOSE command. The server_entry became
6836 invalid but was referenced later in the command. Affected file
6839 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Fixed fatal bug in failure packet handling. Server ignored
6842 the failure and thus crashed when it came.
6846 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6849 that the command may be executed only once in (about) 2 seconds.
6850 The old SILC_CF_LAG flag is same but allows command bursts up
6851 to five before limiting.
6853 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6854 server code. Various commands now includes the CF_LAG_STRICT
6855 flag to disallow any kind of miss-use of the command.
6857 * Fixed the silc_buffer_unformat to not to allocate any data
6858 if the length of the data is zero. It used to allocate the
6859 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6861 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Changed the format of AdminConnection configuration section
6864 in the server. Added username of the admin to the format.
6865 Affected files silcd/serverconfig.[ch].
6867 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6868 to return admin configuration data by host, username and/or
6871 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Implemented WHOWAS command to the server. Added the functions:
6875 silc_server_command_whowas_parse,
6876 silc_server_command_whowas_send_reply,
6877 silc_server_command_whowas_from_client and
6878 silc_server_command_whowas_from_server
6880 * Added <Client ID> argument to the WHOWAS command reply. Updated
6881 the protocol specs accordingly.
6883 * Implemented WHOWAS command and command_reply to the client
6886 Implemented the WHOWAS printing on the user interface.
6888 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Added new argument to the WHOWAS command reply, the real name.
6891 It is an optional argument. Updated the protocol specs.
6893 * Added SilcIDCacheDestructor callback that is registered when
6894 the SilcIDCache is allocated. The callback is called when
6895 an cache entry in the ID Cache expires, or is purged from the
6896 cache. Added into lib/silccore/idcache.[ch].
6898 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6899 to destruct the client entries when the cache entry expires.
6900 Other ID Cache's in server and in the client library ignores
6903 * If the ID Cache entry's `expire' field is zero then the entry
6904 never expires. Added boolean `expire' argument to the
6905 silc_idcache_add function in the lib/silccore/idcache.[ch].
6906 If it is TRUE the default expiry value is used.
6908 * Added silc_server_free_client_data_timeout that is registered
6909 when client disconnects. By default for 5 minutes we preserve
6910 the client entry for history - for WHOWAS command.
6912 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added support to the server to enforce that commands are not
6915 executed more than once in 2 seconds. If server receives
6916 commands from client more frequently, timeout is registered
6917 to process the commands. Affected file silcd/command.c.
6918 Added new function silc_server_command_process_timeout.
6920 * Changed NICK_NOTIFY handling in client library to check that
6921 if the client's nickname was changed, so there is no need to
6922 resolve anything from the server.
6924 * Removed error printing from the WHOIS and IDENTIFY commands.
6925 If error occurs then it is ignored silently in the client library.
6926 The application, however, may map the received error to
6927 human readable error string. The application currently maps
6928 the NO_SUCH_NICKNAME error to string.
6930 * Made the command status message public to the application. Moved
6931 them from lib/silcclient/command_reply.c to
6932 lib/silcclient/command_reply.h. The application can map the
6933 received command status to the string with the
6934 silc_client_command_status_message function.
6936 * Added check to the server to check that client's ID is same
6937 as the Source ID in the packet the client sent. They must
6940 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Added dist-bzip hook to the Makefile.am to make bzip2
6943 compressed distributions.
6945 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Server now enforces the maximum length for the nickname and
6948 the channel as protocol specification dictates. 128 bytes for
6949 nickname and 256 bytes for channel name.
6951 * Moved the WHOIS printing to the application. The client libary
6952 does not print out the WHOIS information anymore, the application
6953 must do it. Renamed silc_client_command_reply_whois_print to
6954 the silc_client_command_reply_whois_save.
6956 The client's idle time is also sent to the application now, and
6957 the idle is shown on screen.
6959 * Added silc_client_command_reply_identify_save to save the
6960 received IDENTIFY entries.
6962 * Do not check for channel private keys in message sending and
6963 reception if the channel does not have the PRIVKEY mode set.
6964 Affected file lib/silclient/client_channel.c.
6966 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6969 just surfaced after chaning the JOIN procedure.
6971 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added silc_client_get_clients_by_list to get client entries
6974 from Client ID list, that is returned for example by JOIN
6975 and USERS command replies. The application should use this
6976 function for example when JOIN command reply is received to
6977 resolve the clients already on the channel (library does not
6978 do that anymore as USERS command reply is not used in the JOIN
6979 procedure anymore). Affected files lib/silcclient/silcapi.h and
6980 lib/silcclient/idlist.c.
6982 * JOIN command reply and USERS command reply returns now SilcBuffer
6983 pointers instead of unsigned char pointers when returning
6984 the client list and mode list.
6986 * Added <Client ID> argument to the JOIN command reply, mainly
6987 for the server to identify for which client the command was
6988 originally sent. Updated protocol specs accordingly.
6990 * Added SilcDlist private_key pointer to the SilcChannelEntry
6991 in the client to support the channel private keys. Affected
6992 file is lib/silcclient/idlist.h.
6994 * Added SilcChannelPrivateKey argument to the function
6995 silc_client_send_channel_message so that application can choose
6996 to use specific private ke if it wants to. If it is not provided,
6997 the normal channel key is used, unless private keys are set.
6998 In this case the first (key that was added first) is used
6999 as the encryption key.
7001 * Implemented the support for channel private key handling.
7002 Implemented the following functions:
7004 silc_client_add_channel_private_key,
7005 silc_client_del_channel_private_keys,
7006 silc_client_del_channel_private_key,
7007 silc_client_list_channel_private_keys and
7008 silc_client_free_channel_private_keys
7010 Affected file lib/silcclient/client_channel.c.
7012 * Added the support for the private keys in the channel message
7013 sending and encryption and in the message reception and
7014 decryption. Affected funtions are
7015 silc_client_send_channel_message and silc_client_channel_message.
7017 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7019 * Added SKE's key verify callback to the client library's
7020 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7022 * Removed the statement that server (or router) must send USERS
7023 command reply when joining to the channel so that the client
7024 knows who are on the channel. Instead, the client list and
7025 client's mode list is now sent in the JOIN command reply to the
7026 client who joined channel. This is better solution.
7028 * Added function silc_server_get_users_on_channel and function
7029 silc_server_save_users_on_channel to the silcd/server.[ch].
7031 * Removed function silc_server_command_send_users from the
7034 * Do not show topic on the client library anymore. The topic is
7035 sent in the command reply notify to the application and the
7036 application must show the topic now.
7038 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Added client searching by nickname hash into the IDENTIFY and
7041 WHOIS commands in the server as they were clearly missing from
7042 them. Affected file is silcd/command.c.
7044 * Fixed a bug in private message receiving in the client library.
7045 The remote ID was freed and it wasn't supposed, now it is
7048 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Minor fix to the channel payload; allocate the data area, as it
7051 needs to be of specific length.
7053 * If the key agreement port is zero then the operating
7054 system will define the bound port. Affected files are
7055 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7057 * Added new function silc_channel_payload_decrypt into the file
7058 lib/silccore/silcchannel.[ch].
7060 * Moved the channel message etc, check from silc_packet_decrypt
7061 to applications. The library calls now a generic
7062 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7063 when the packet is either normal or special. This was done to
7064 allow more wide range of checking that was not allowed when
7065 the code was in library. Now applications can do virtually any
7066 checks to the packet and return to the library the decision how
7067 the packet should be processed. Affected files are
7068 lib/silccore/silcpacket.[ch].
7070 Added silc_server_packet_decrypt_check to the server and
7071 silc_client_packet_decrypt_check to the client library.
7073 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7074 to send with specified source and destination information.
7076 * Channel message delivery between routers was broken after the
7077 channel key distribution was fixed earlier. The channel key
7078 was used be to distributed to other routers as well which is not
7079 allowed by the protocol. Now this is fixed and channel keys
7080 really are cell specific and the channel message delivery between
7081 routers comply with the protocol specification.
7083 * Fixed various commands in server to check also the global list
7084 for the channel entry and not just the local list. The affected
7085 file silcd/command.c.
7087 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Added assert()s to buffer formatting and unformatting routines
7090 to assert (if --enable-debug) when error occurs. Affected
7091 file: lib/silcutil/silcbuffmt.c.
7093 * Changed to auto-reconnect to check whether the remote host is
7094 router and register the re-connect timeout if it is. It used
7095 to check that whether we are normal server, but router must do
7096 auto-reconnect with another router as well. Affected file
7099 * Removed the [<key len>] option from CMODE command as the cipher
7100 name decides the key length, nowadays. See the defined ciphers
7101 from the protocol specification.
7103 * Added [<hmac>] option to the CMODE command to define the HMAC
7104 for the channel. Added SILC_CMODE_HMAC channel mode.
7106 * Added [<hmac>] option for the JOIN command so that user can
7107 select which HMAC is used to compute the MACs of the channel
7110 * Added Hmac field to the Channel Message Payload. The integrity
7111 of plaintext channel messages are now protected by computing
7112 MAC of the message and attaching the MAC to the payload. The
7113 MAC is encrypted. Now, it is clear that this causes some
7114 overhead to the size of the packet but rationale for this is that
7115 now the receiver can verify whether the channel message decrypted
7116 correctly and also when private keys are set for the channel the
7117 receiver can decrypt the packet with several keys and check from
7118 the MAC which key decrypted the message correctly.
7120 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7121 lib/silccrypt/silccipher.[ch].
7123 * Added silc_hash_len to return the digest length into the
7124 lib/silcrypt/silchash.[ch].
7126 * Rewrote parts of Silc Channel Payload interface in the
7127 lib/silccore/silcchannel.[ch]. The encode function now also
7128 encrypts the packet and parse function decrypts it.
7130 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Fixed a minor formatting bug in the SKE's key material processing.
7133 It actually might have processed the keys wrong way resulting
7136 * Redefined the mandatory HMAC algorithms and added new algorithms.
7137 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7138 and hmac-md5 truncated to 96 bits. The mandatory is now
7139 hmac-sha1-96. Rest are optional (including the one that used
7140 to be mandatory). Rationale for this is that the truncated HMAC
7141 length is sufficient from security point of view and can actually
7142 make the attack against the HMAC harder. Also, the truncated
7143 HMAC causes less overhead to the packets. See the RFC2104 for
7146 * Added new [hmac] configuration section. The SKE used to use
7147 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7148 is of course wrong. The official names that must be proposed in
7149 the SKE are the ones defined in the protocol specification
7150 (hmac-sha1-96 for example). The user can configure any hmac
7151 using any hash function configured in the [hash] section. At
7152 least, the mandatory must be configured.
7154 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7156 * Added HMAC list to the SKE proposal list. It has now both
7157 hash algorithm list and HMAC list. This makes the protocol
7158 incompatible with previous versions. The SKE now seems to work
7159 the way it is supposed to work, for the first time actually.
7161 * Defined plain Hash algorithms to the protocol specification.
7164 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Implemented support for key agreement packets into the server.
7167 Added functions silc_server_key_agreement and
7168 silc_server_send_key_agreement. Other than these functions,
7169 server has nothing to do with this packet.
7171 * Added support for private message key packets into the server.
7172 Added functions silc_server_private_message_key and
7173 silc_server_send_private_message_key.
7177 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7178 called in the protocol's final callback instead in the END
7179 protocol state. This makes a little more sense and in the same
7180 time in client we can use the same protocol routines for normal
7181 key exchange and to key agreement packet handling as well.
7183 * Added to both client's and server's KE protocol context the
7184 SilcSKEKeyMaterial pointer to save the key material. We will
7185 bring the key material to the protocol's final callback by doing
7186 this. The final callback must free the key material.
7188 * Added SKE's packet_send callback into client's KE protocol
7189 context so that the caller can choose what packet sending function
7190 is used. This way we can use different packet sending when
7191 doing normal SKE when doing key agreement packet handling (in
7192 the key agreement packet handling we do not want to encrypt
7195 * Implemented the responder side of the key agreement routines
7196 in the client. The client can now bind to specified port and
7197 accept incoming key negotiation. The key material is passed
7198 to the application after the protocol is over.
7200 * Implemented the processing of incoming Key Agreement packet
7201 in the client. Added function silc_client_key_agreement to
7204 * Implemented the intiator side of the key agreement routines
7205 in the client. The client can now initiate key agreement with
7206 another remote client. The key material is passed to the
7207 application after the protocol is over.
7209 * Created client_keyagr.c to include all the key agreement
7212 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7213 SILC_TASK_CALLBACK except that it is not static.
7215 * Created client_notify.c and moved the Notify packet handling
7216 from the client.[ch] into that file.
7218 * Created client_prvmsg.c and moved all private message and
7219 private message key routines from the client.[ch] into that file.
7221 * Create client_channel.c and moved all channel message and
7222 channel private key routines from the client.[ch] into that file.
7224 * Changed silc_client_get_client_by_id_resolve to resolve with
7225 WHOIS command instead of IDENTIFY command, in the file
7226 lib/silclient/idlist.c.
7228 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Implemented the SKE's responder side to the Client library.
7232 * When FAILURE is received to the protocol do not trust it
7233 blindly. Register a timeout to wait whether the remote closes
7234 the connection as it should do it, only after that process the
7235 actual failure. This was changed to both client and server.
7237 * Added client_internal.h to include some of the structures
7238 there instead of client.h in lib/silcclient/.
7240 * Added function silc_task_unregister_by_callback to unregister
7241 timeouts by the callback function.
7243 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Some "Incomplete WHOIS info" errors has been appearing on the
7246 log files. Took away the entry->userinfo check from WHOIS
7247 reply sending. The entry->userinfo is now " " if client did not
7248 provide one. I thought this was fixed earlier but something
7249 is wrong still. Let's see if the error still appears.
7251 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7253 * Fixed a minor bug in the login when the channel key is
7254 re-generated in the server. It used to generate the key in
7255 wrong order and thus caused problems in the channel traffic.
7257 * Fixed a minor bug in channel key distsribution after
7258 KICK command. The key was not sent to the router even though
7261 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Added silc_ske_process_key_material_data as generic routine
7264 to process any key material as the SILC protocol dictates. The
7265 function is used by the actual SKE library but can be used by
7266 applications as well. This relates to the private message keys
7267 and the channel private keys since they must be processed the
7268 same way the normal SILC session keys. The protocol dictates
7269 this. Affected files: lib/silcske/silcske.[ch].
7271 Added also silc_ske_free_key_material to free the
7272 SilcSKEKeyMaterial structure.
7274 * Defined silc_cipher_set_key function to set the key for
7275 cipher without using the object's method function. The affected
7276 files: lib/silccrypt/silccipher.[ch].
7278 * Implemented silc silc_client_add_private_message_key,
7279 silc_client_add_private_message_key_ske,
7280 silc_client_del_private_message_key,
7281 silc_client_list_private_message_keys and
7282 silc_client_free_private_message_keys functions in the
7285 Added functions silc_client_send_private_message_key to send
7286 the Private Message Key payload and silc_client_private_message_key
7287 to handle incoming Private Message Key payload.
7289 * Added Cipher field to the Private Message Key payload to set
7290 the cipher to be used. If ignored, the default cipher defined
7291 in the SILC protocol (aes-256-cbc) is used.
7293 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Removed lib/silcclient/ops.h file.
7297 Redefined parts of the SILC Client Library API. Created new
7298 file silcapi.h that deprecates the ops.h file and defines the
7299 published Client Library API. Defined also private message key
7300 API and channel private key API into the file.
7302 This is the file that the application must include from the
7303 SILC Client Library. Other files need not be included by
7304 the application anymore.
7306 * Added new key_agreement client operation callback and also
7307 defined the Key Agreement library API for the application.
7309 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7311 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7312 is used by clients to request key negotiation between another
7313 client in the SILC network. If the negotiation is started it
7314 is performed using the SKE protocol. The result of the
7315 negotiation, the secret key material, can be used for example
7316 as private message key.
7318 Implemented the Key Agreement payload into the files
7319 lib/silccore/silauth.[ch].
7321 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7323 * Redefined ciphers for the SILC protocol. Added some new ciphers
7324 and defined the key lengths for the algorithms. Changed the
7325 code accordingly. The default key length is now 256 bits.
7327 * Fixed SKE key distribution function silc_ske_process_key_material
7328 when the key length is more than 128 bits. The default key
7329 length in SILC is now 256 bits.
7331 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7332 to indicate unsupported algorithm.
7334 * Renamed rijndael.c to aes.c and all functions as well.
7336 * Fixed a long standing channel key setting bug in client library.
7337 Weird that it has never surfaced before.
7339 * Fixed bug in channel deletion. If the entire channel is removed
7340 then it must also delete the references of the channel entry
7341 from the client's channel list as the client's channel entry and
7342 the channel's client entry share same memory.
7344 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7346 * Implemented CONNECT and SHUTDOWN commands in the client.
7348 * Implemented CLOSE command to the client.
7350 * Added the function silc_idlist_find_server_by_name into the
7351 files silcd/idlist.[ch].
7353 Added the function silc_idlist_find_server_by_conn into the
7354 files silcd/idlist.[ch].
7356 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7358 * DIE command was renamed to SHUTDOWN. Updated the both code
7361 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7362 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7364 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7367 * Added function silc_server_create_connection function to create
7368 connection to remote router. My server implementation actually
7369 does not allow router to connect to normal server (it expects
7370 that normal server always initiates the connection to the router)
7371 so the CONNECT command is only good for connecting to another
7374 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7376 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7377 or some other client was kicked from the channel.
7379 Implemented the handling of the notify type to both client
7382 Implemented silc_server_send_notify_kicked to send the KICKED
7383 notify. It is used to send it to the server's primary router.
7385 * Implemented the KICK command into server and client.
7387 * Added `query' argument to the silc_idlist_get_client function
7388 to indicate whether to query the client from server or not if
7391 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7392 to indicate that the client is not channel founder.
7396 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7398 * Removed the rng context from SilcPacketContext structure and
7399 changed that the packet routine uses the Global RNG API.
7401 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7403 * Added support for quit message that client can "leave" on the
7404 channel when it quits the SILC. It is ditributed inside the
7405 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7407 Added silc_server_free_client_data that will take the
7408 signoff message as argument.
7410 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7412 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * Updated parts of the protocol specification to keep it up
7417 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7420 payloads in one packet.
7422 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7423 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7424 use now the new List flag.
7426 * Also deprecated the following packet types: REPLACE_ID,
7427 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7429 * Added list support for Notify packet in server.
7431 * Added silc_server_send_notify_channel_change to send the
7432 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7433 the silc_server_send_replace_id.
7435 * Added silc_server_send_notify_nick_change to send the
7436 NICK_CHANGE notify type. Deprecates the function
7437 silc_server_send_replace_id.
7439 * Added silc_server_send_notify_join to send the JOIN notify type.
7440 Deprecates the function silc_server_send_new_channel_user.
7442 * Added silc_server_send_notify_leave to send LEAVE notify type.
7443 Deprecates the function silc_server_send_remove_channel_user.
7445 * Added silc_server_send_notify_cmode and
7446 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7447 types. Deprecates the silc_server_send_set_mode function.
7449 * Added SERVER_SIGNOFF notify type to indicate that server has
7450 quit. This means that all clients on the channel from that
7451 server will drop. This can be also used when netsplit happens.
7453 Deprecated REMOVE_ID packet type since it is not needed anymore
7456 Added silc_server_send_notify_server_signoff to send the
7457 SERVER_SIGNOFF notify type. Deprecates the function
7458 silc_server_send_remove_id.
7460 Added also silc_server_send_notify_signoff to send the
7461 SIGNOFF notify type.
7463 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7464 SILC protocol from this day on. Changed the protocol
7465 specification as well.
7467 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7468 notify type. It is used between routers to notify about
7469 topic changes on a channel.
7471 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7474 * Partly updated the protocol specification to comply with the
7475 changes now made. It is still though a bit outdated.
7477 * The JOIN notify type now takes one extra argument <Channel ID>.
7478 The packet used to be destined to the channel but now the
7479 JOIN type may be sent as list thus it is impossible to
7480 destine it to any specific channel. By adding this argument
7481 it is again possible.
7483 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7485 * Added CREDITS file. The CHANGES and CREDITS file will appear
7486 in the distribution as well.
7488 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7490 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7491 types in the server's silcd/packet_receive.c.
7493 * Implemented CMODE and CUMODE to work in router environment.
7495 * Fixed minor encoding and decoding buglet from the
7496 lib/silccore/silcmode.c.
7498 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7501 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7503 * Changed all SilcConfigServer* and silc_config_server* to
7504 SilcServerConfig* and silc_server_config*, respectively.
7507 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * Associated the ID (client or server ID) to the Authentication
7510 Payload to avoid any possibility of forging. Updated the
7511 protocol specification and the code accordingly.
7513 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * The RSA key length is now save to the RsaKey context in the
7516 key generation process in lib/silccrypt/rsa.c. The key length
7517 is now used to figure out the maximum size of the block allowed
7518 to be encrypted/signed.
7520 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7521 is equivalent to the silc_mp_mp2bin but does not allocate any
7524 * Changed silc_mp_mp2bin API to take length argument. If it is
7525 non-zero then the buffer is allocated that large. If zero, then
7526 the size is approximated using silc_mp_sizeinbase, which however
7529 * Created Global RNG API which is global RNG that application can
7530 initialize. After initializing, any routine anywhere in the
7531 code (including library) can use RNG without allocating a new
7532 RNG object. This was done to allow this sort of use of the
7533 RNG in code that has no chance to allocate RNG object. All
7534 applications currently allocate this and many routines in the
7535 library use this. Affected file lib/silccrypt/silcrng.[ch].
7537 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7538 it to use the Global RNG API.
7540 * Defined Authentication Payload into protocol specification that
7541 is used during SILC session to authenticate entities. It is
7542 used for example by client to authenticate itself to the server
7543 to obtain server operator privileges.
7545 Implemented this payload into the lib/silccore/silcauth.[ch].
7546 Implemented also routines for public key based authentication
7547 as the new protocol specification dictates.
7549 Moved definitions of different authentication methods from
7550 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7552 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7553 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7554 silc_pkcs_verify_with_hash functions into the file
7555 lib/silccrypt/silcpkcs.[ch].
7557 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * The client entry's userinfo pointer must be always valid.
7560 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7561 will fail since it requires the userinfo. Now, the userinfo
7562 is allocated as "" if actual userinfo does not exist. Actually,
7563 it must exist and it is totally Ok to drop client connections
7564 that does not announce the userinfo. However, we will make
7565 this workaround for now.
7567 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7568 to return the remote port by socket.
7570 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7572 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7573 SILC_SERVER_PENDING_EXEC and added an new macro
7574 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7575 data or when error occurs while processing the pending command.
7577 Added new argument `destructor' into silc_server_command_pending
7578 and to the SilcServerCommandPending object. This destructor is
7579 now called after calling the pending callback or if error occurs
7580 immediately. If error occurs the actual pending callback won't
7581 be called at all - only the destructor. The destructor may be
7582 NULL if destructor is not needed.
7584 All this applies for client library code as well. Similar
7585 changes were made there as well for the pending commands.
7587 In the client, the application must now allocate the
7588 SilcClientCommandContext with the silc_client_command_alloc
7591 * Added reference counter to the SilcServerCommandContext. Added
7592 function silc_server_command_alloc and silc_server_command_dup
7595 Same type of functions added to the client library for the same
7598 * Removed the cmd_ident from IDListData away since it is now
7599 global for all connections. It is the command identifier used
7600 in command sending and with pending commands. The affected file
7603 * Added reference counter to the SilcSocketConnection objecet to
7604 indicate the usage count of the object. The object won't be
7605 freed untill the reference counter hits zero. Currently only
7606 server uses this, and client ignores it. The client must be
7607 set to use this too later. The affected files are
7608 lib/silccore/silcsockconn.[ch]. Added also the function
7609 silc_socket_dup to increase the reference counter.
7611 This was mainly added because it is possible that the socket
7612 is removed underneath of pending command or other async
7613 operation. Now it won't be free'd and proper DISCONNECTING
7614 flags, etc. can be set to avoid sending data to connection that
7615 is not valid anymore.
7617 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7618 the connection. After that it sets SILC_SET_DISCONNECTED.
7619 It is, however, possible that the socket data is not still freed.
7620 The silc_server_packet_process now checks that data is not
7621 read or written to connection that is DISCONNECTED. The socket
7622 get's freed when the reference counter hits zero.
7624 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Changed the client operation API: channel_message operation's
7627 `sender' is now the client entry of the sender, not the nickname
7628 and the `channel' is the channel entry, not the channel name.
7630 In the private_message operation the `sender' is now also the
7631 client entry of the sender not the nickname.
7633 Affected file is lib/silcclient/ops.h and all applications
7634 using the client operations.
7636 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7638 * Moved the calling of ops->connect() from connect_to_server_final
7639 into receive_new_id functin since that is the point when the
7640 client is actually allowed to send traffic to network. The
7641 affected file is lib/silcclient/client.c.
7643 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7646 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7647 (if needs broadcasting) instead of broadcasting the packets one
7648 by one which would make a burst in the network traffic.
7650 * Added `broadcast' argument to the functions in silcd/server.[ch]
7651 silc_server_create_new_channel[_with_id] to indicate whether
7652 to send New Channel packet to primary router.
7654 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7656 * Added new function into the silcd/server.[ch] files:
7657 silc_server_create_new_channel_with_id to create new channel with
7658 already existing Channel ID.
7660 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7661 lib/silccore/silcpacket.h. This packet is used t send list of
7662 Set Mode payloads inside one packet. Server uses this to set
7663 the modes for the channels and clients on those channels, that it
7664 announced to the router when it connected to it. The protocol
7665 specification has been updated accordingly.
7667 * The silc_server_new_channel did not handle the packet coming
7668 from normal server as it normally does not send that. However,
7669 when it announces its channels it does send it. Implemented
7670 the support for that.
7672 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7673 into the file lib/silccore/id.h.
7675 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Fixed memory leaks in the functions silc_idlist_del_client,
7678 silc_idlist_del_channel and silc_idlist_del_server in the file
7679 silcd/idlist.c. All of those leaked like a sieve.
7681 * Fixed some small memory leaks in the client's function
7682 silc_client_notify_by_server.
7684 * Added functions into silcd/server.c: silc_server_announce_clients,
7685 silc_server_announce_channels and silc_server_announce_server.
7686 These functions are used by normal and router server to announce
7687 to its primary router about clients, channels and servers (when
7688 router) that we own. This is done after we've connected to the
7691 These functions effectively implements the following packet types:
7692 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7693 and SILC_PACKET_NEW_ID_LIST.
7695 * Added new functions into the silcd/packet_receive.[ch]:
7696 silc_server_new_id_list, silc_server_new_channel_list and
7697 silc_server_new_channel_user_list to handle the incoming
7698 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7700 * Added support of changing Channel ID in the function
7701 silc_server_replace_id. If the server that announces a channel
7702 to the router already exists in the router (with same name but
7703 with different Channel ID), router is responsible to send
7704 Replace ID packet to the server and force the server to change
7705 the Channel ID to the one router has.
7707 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7708 client that the Channel ID has been changed by the router. The
7709 normal server sends this to the client. Client must start using
7710 the new Channel ID as the channel's ID.
7712 Implemented handling of this new type into lib/silcclient/client.c
7713 into the function silc_client_notify_by_server.
7715 * Added new function silc_idlist_replace_channel_id into the files
7716 silcd/idlist.[ch] to replace the Channel ID.
7718 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7720 * Call silc_server_command_identify_check always when processing
7721 the IDENTIFY command in silcd/command.c
7723 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7725 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7726 send keepalive packets. The packet can be sent by clients,
7727 servers and routers.
7729 Added function silc_socket_set_heartbeat into the file
7730 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7731 If not set, the heartbeat is not performed. The actual
7732 heartbeat is implemented in the low level socket connection
7733 library. However, application is responsible of actually
7736 Added silc_server_send_heartbeat to send the actual heartbeat
7737 packet into silcd/packet_send.[ch]. Server now performs
7738 keepalive with all connections.
7740 * Added silc_task_get_first function into lib/silcutil/silctask.c
7741 to return the timeout task with shortest timeout. There was a bug
7742 in task unregistration that caused problems. TODO has been
7743 updated to include that task system must be rewritten.
7745 * The client library will now resolve the client information when
7746 receiving JOIN notify from server for client that we know but
7747 have incomplete information.
7749 * Rewrote parts of silc_server_remove_from_channels and
7750 silc_server_remove_from_one_channel as they did not remove the
7751 channel in some circumstances even though they should've.
7753 * Encryption problem encountered in server:
7755 The LEAVE command used to send the Channel Key packet to the
7756 router immediately after generating it. However, the code
7757 had earlier sent Remove Channel user packet but not immediately,
7758 ie. it was put to queue. The order of packets in the router
7759 was that Channel Key packet was first and Remove Channel User
7760 packet was second, even though they were encrypted in the
7761 reverse order. For this reason, MAC check failed. Now, this
7762 is fixed by not sending the Channel Key packet immediately but
7763 putting it to queue. However, this is more fundamental problem:
7764 packets that are in queue should actually not be encrypted
7765 because packets that are sent immediately gets encrypted
7766 actually with wrong IV (and thus MAC check fails). So, packets
7767 that are in queue should be encrypted when they are sent to
7768 the wire and not when they put to the queue.
7770 However, the problem is that the current system has not been
7771 designed to work that way. Instead, the packet is encrypted
7772 as soon as possible and left to the queue. The queue is then
7773 just purged into wire. There won't be any fixes for this
7774 any time soon. So, the current semantic for packet sending
7777 o If you send packet to remote host and do not force the send
7778 (the packet will be in queue) then all subsequent packets to the
7779 same remote host must also be put to the queue. Only after the
7780 queue has been purged is it safe again to force the packet
7783 o If you send all packets immediately then it safe to send
7784 any of subsequent packets through the queue, however, after
7785 the first packet is put to queue then any subsequent packets
7786 must also be put to the queue.
7788 Follow these rules and everything works fine.
7790 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Added new function silc_server_remove_clients_by_server to
7793 remove all client entries from ID list when the server connection
7794 is lost. In this case it is also important to invalidate all
7795 client entires as they hold the invalid server entry. This
7796 fixes fatal bug when server has lost connection and will reconnect
7799 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7801 * Made some sanity checks to silc_server_daemonise like to check
7802 whether the requested user and group actually exists.
7804 * Added sanity check to SKE's silc_ske_responder_finish to check
7805 that the public and private key actually is valid.
7807 * Invalidate the client's nickname when receiving Replace ID
7808 packet and the Client ID is being replaced. This means that the
7809 server will query the nickname if someone needs it (client)
7812 * Sort the ID Cache in client library when the ID Cache data
7813 has changed (needs sorting).
7815 * Do not allow for SILC client to create several connections to
7816 several servers. The client does not support windows right now
7817 and generating multiple connections causes weird behaviour.
7819 Irssi-silc client does support windows and can handle several
7820 connections without problems, see: www.irssi.org and SILC plugin.
7822 * Fixed some places where client was added to the IDList. The
7823 rule of thumb is following (in order to get everything right):
7824 If the client is directly connected local client then the
7825 `connection' argument must be set and `router' argument must be
7826 NULL to silc_idlist_add_client function. If the client is not
7827 directly connected client then the `router' argument must
7828 bet set and the `connection' argument must be NULL to the
7829 silc_idlist_add_client function.
7831 * The funtion silc_server_packet_send_local_channel actually did
7832 not check whether the client was locally connected or not. It
7833 does that now. Fixed a bug related to LEAVE command.
7835 * Fixed Remove Channel User payload parsing bug in server's
7836 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7838 * The server's silc_server_save_channel_key now checks also the
7839 global ID list for the channel as it might not be in the local
7840 list. Fixed a bug related to LEAVE command.
7842 * Is this the end of the [<unknown>] buglet that has been lurking
7843 around for a long time? A little for loop fix in server's
7844 silc_server_command_whois_parse that is used by both IDENTIFY
7845 and WHOIS command. At least, this was a clear bug and a cause
7846 of one type of [<unknown>] buglet.
7848 * WHOIS and IDENTIFY commands call the function
7849 silc_server_command_[whois/identify]_check function even if
7850 we are not router server.
7852 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7854 * Added --with-gmp configuration option. If set the GMP
7855 is always compiled in the SILC source tree. If not set then
7856 it is checked whether the system has the GMP3 installed. If
7857 it has then the GMP won't be compiled (the system's headers
7858 and library is used), if it doesn't have it then the GMP is
7859 compiled in the SILC source tree.
7861 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Changed RSA private exponent generation to what PKCS #1
7864 suggests. We try to find the smallest possible d by doing
7865 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7866 not security fix but optimization.
7868 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7870 * Added new config entry [Identity] to fork the server and run
7871 it as specific user and group. A patch from Bostik.
7873 * Imported Dotconf configuration library into lib/dotconf.
7874 This will be used to create the SILC configuration files later.
7875 It will appear in the distsribution after this commit.
7877 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7879 * A big code auditing weekend happening. Auditing code for
7880 obvious mistakes, bugs and errors. Also, removing any code
7883 Removed files for being obsolete:
7885 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7886 inline in the file lib/silcutil/silcbuffer.h)
7888 o lib/silcutil/silcbufutil.c (the header has inline versions)
7890 Changed code to fix possible error conditions:
7892 o The buffer formatting routines now check that the destination
7893 buffer really has enough space to add the data. This applies for
7894 both buffer formatting and unformatting
7895 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7896 unformatting was changed to accomodate following rules:
7897 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7898 sent to the function while XXX_*STRING will not allocate or copy
7899 the data into the buffer. Instead it sets the pointer from the
7900 buffer into the pointer sent as argument (XXX_*STRING used to
7901 require that the pointer must be allocated already). This change
7902 makes this whole thing a bit more consistent and more optimized
7903 (note that the data returned in the unformatting with XXX_*STRING
7904 must not be freed now). The routines return now -1 on error.
7906 o Tried to find all code that use buffer_format and buffer_unformat
7907 and added return value checking to prevent formatting and
7908 especially unformatting errors and possible subsequent fatal
7911 o Changed ske->x and ske->KEY to mallocated pointers in
7912 lib/silcske/silcske.h. Fixed possible data and memory leak.
7914 o Added return value checking to all *_parse* functions. Fixed
7915 many memory leaks as well.
7917 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7918 so that buffer overflows would not happen. All code now also
7919 checks the return value as it can fail.
7921 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7923 * Added reconnection support to server if the normal server looses
7924 its connection to the router (for example if router is rebooted).
7925 The server performs normal reconnection strategy implemented
7926 to the server. Affected file silcd/server.c.
7928 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7930 * Added new packet type SILC_PACKET_SET_MODE that is used to
7931 distribute the information about changed modes (for clients,
7932 channels and clients channel modes) to all routers in the
7933 network. Updated the protocol specification accordingly.
7935 Added functions into silcd/packet_send.c and
7936 silcd/packet_receive.c: silc_server_send_set_mode,
7937 silc_server_set_mode.
7939 Added new files silcmode.[ch] into lib/silccore that implements
7940 the encoding and decoding of Set Mode Payload. Added new type
7941 SilcSetModePayload. Moved the definitions of different modes
7942 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7944 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7946 * Oops, a little mistake in server's connection authentication
7947 protocol. The protocol is not ended with FAILURE but with
7948 SUCCESS if the authentication is Ok. :) Affected file is
7951 * Implemented NICK_CHANGE notify handling in server in the file
7952 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7953 the local clients on the channel. After the changing nickname
7954 in router environment snhould work and the [<unknown>] nickname
7955 should appear no more.
7957 The silc_server_replace_id function that receives the Replace ID
7958 payload now sends the NICK_CHANGE notify type also in the file
7959 silcd/packet_receive.c
7961 * Changed WHOIS and IDENTIFY command to support the maximum amount
7962 of arguments defined in protocol specs (3328 arguments). This
7963 fixed a bug that caused problems when there were more than three
7966 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7968 * Added extra parameter, command identifier, to the
7969 silc_client_send_command so that explicit command identifier
7972 Changed that ID list routines uses specific command identifier
7973 when sending WHOIS/IDENTIFY requests to the server so that they
7974 can be identified when the reply comes back.
7976 Affected files lib/silcclient/command.[ch],
7977 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7979 * Added `sender' argument to silc_server_packet_send_to_channel
7980 to indicaet the sender who originally sent the packet to us
7981 that we are now re-sending. Ignored if NULL. Affected file
7982 silcd/packet_send.[ch].
7984 * Added some server statistics support in silcd/server_internal.h
7985 SilcServerStatistics structure and around the server code. Also
7986 send some nice statistics information when client is connecting
7989 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7991 * Fixed channel ID decoding in server's JOIN command reply in
7992 silcd/command_reply.c
7994 * Fixed braodcasting of replace ID payload to not to send it if
7995 we are standalone server in silcd/packet_receive.c.
7997 * Fixed all channel message sending routines to not to send
7998 packets to clients that has router set, since they are routed
7999 separately in the same function earlier. Affects file
8000 silcd/packet_send.c and all channel packet sending functions.
8002 * In USERS reply, res_argv[i] are not allocated, the table
8003 is allocated. Thus changed that free the table, not its
8006 * In server's whois_check and identify_check if the client is
8007 locally connected do not send any WHOIS commands - they are not
8010 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8012 * Fixed some minor bugs in client when sending WHOIS command. The
8013 arguments was in wrong order.
8015 * Removed statis function add_to_channel from server in
8016 silcd/command.c that was previously used with the joining but
8019 * Tested USERS command in router environment successfully with two
8020 routers, two servers and two clients.
8022 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8024 * Reorganized the USERS command and command reply in client library
8025 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8026 When the command is given by user we register a pending command
8027 callback that will reprocess the command after the reply has been
8028 received from the server. When reprocessing the packet we then
8029 display the information. Thus, the USERS information is displayed
8030 now in the command callback instead of in the command reply
8031 callback. The processing of the command is same as previously
8032 when server has sent the command reply in the JOINing process.
8034 * Added to USERS command in silcd/command_reply.c to join the client,
8035 we didn't use to know about, to the channel after we've created
8036 a client entry for it. Also, for clienet we did know already still
8037 check whether it is on the channel or not and add it if not.
8039 * Removed silc_server_command_join_notify as the function and its
8042 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8044 * Changed the client's pending command handling to the same as the
8045 server's pending command handling. It is also now possible to
8046 execute command reply functions from other command reply
8047 function as the function callbacks for commands and command
8048 replies are one and same. The pending commands are not static
8049 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8050 in client connection context. Thus, pending commands are server
8051 connection specific as it is convenient.
8053 Changed the function silc_client_command_pending and
8054 silc_client_command_pending_del and added new function
8055 silc_client_command_pending_check. Removed the
8056 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8059 * Added cmd_ident, current command identifier, to the client
8060 connection context in lib/silcclient/client.h to keep track on
8061 command identifiers used in command sending. Client's command reply
8062 function handling now supports the mandatory command identifiers.
8064 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8065 funtions in client to fully support pending command callbacks.
8067 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8068 as one of the arguments to the application in the command reply
8071 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8072 before first releasing SILC but came back. Now it is removed again
8073 and should come back nomore. The FORWARDED flag was used only
8074 by the JOINing procedure by forwarding the command packet to router.
8075 Now, the JOINing procedure has been changed to more generic (due
8076 to various router environment issues) and FORWARDED is not needed
8077 anymore for anything. The protocol specification is yet to be
8080 Now, removed silc_server_packet_forward from server and the flag
8081 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8083 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8085 * Renamed NAMES command to USERS command. The NAMES was named that
8086 due to historical reasons. Now it is renamed. Also, rewrote
8087 parts of the USERS command. The nickname list is not sent anymore
8088 by the server. Only Client ID and mode lists are sent in the USERS
8089 command. Changed this also to the protocol specification.
8091 The client now resolves the names and stuff after it receives
8092 the USERS list from the server when joining to the channel.
8094 * WHOIS and IDENTIFY commands has been changed to support multiple
8095 Client ID's per command. One can now search for multiple users
8096 in the network by sending only one WHOIS or IDENTIFY command.
8097 Changed the code and the protocol specifications.
8099 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8100 uses silc_server_command_whois_parse to parse the request. */
8102 * If normal server, do not parse the WHOIS and IDENTIFY requests
8103 before sending it to the router. Saves some time.
8105 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8107 * Fixed JOIN command on client library. Wrong number of arguments
8108 used to crash the client.
8110 * Added silc_server_channel_has_global function to check whether
8111 channel has global users or not.
8113 * Added silc_server_channel_has_local function to check whether channel
8114 has locally connected clients on the channel.
8116 * The silc_server_remove_from_one_channel now checks whether the
8117 channel has global users or not after given client was removed from
8118 the channel. It also checks whether the channel has local clients
8119 on the channel anymore. If it does not have then the channel entry
8120 is removed as it is not needed anymore.
8122 * The silc_server_notify now checks on JOIN notify whether the joining
8123 client is one of locally connected or global. If it is global then
8124 the channel has now global users on the channel and that is marked
8125 to the channel entry. Also, it now saves the global client to
8126 global list who is joining and JOINs it to the channel. This is
8127 for normal server, that is.
8129 Changed silc_server_send_notify_on_channel,
8130 silc_server_packet_relay_to_channel and
8131 silc_server_packet_send_to_channel check if we are normal server
8132 and client has router set (ie. global client) do not send the
8133 message to that client, as it is already routed to our router.
8135 * Implemented LEAVE notify type handling in silc_server_notify
8138 * Tested LEAVE command in router environment successfully. Tested
8139 with two routers, two servers and two clients.
8143 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8145 * Implemented SIGNOFF notify type handling in silc_server_notify
8148 * silc_server_remove_id now removes the client entry from all channels
8149 it has joined and thusly sends SIGNOFF notify type.
8151 * Rewrote the NAMES list generation in server by removing two excess
8152 loops. The lists are created now inside one loop.
8154 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * silc_server_remove_channel_user checks now also global list
8157 for channel and client.
8159 * silc_server_new_channel_user checks now both local and global
8160 list for channel and client. Fixed a bug in client id decoding.
8161 Used to decode wrong buffer.
8163 * silc_server_channel_message checks now both local and global
8164 list for channel entry.
8166 * Tested channel joining (hence JOIN) in router environment
8167 successfully. Tested with two routers, two servers and two
8170 * Tested channel message sending in router environment successfully.
8172 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8174 * Added silc_server_save_channel_key into server.[ch] to save the
8175 received channel key in Channel Key payload processing. It is
8176 also used in JOIN command reply handling.
8178 Equivalent function silc_client_save_channel_key added into
8179 client.[ch] into client library.
8181 * Changed JOIN command reply to send information whether the channel
8182 was created or not (is existing already) and the channel key
8183 payload. Changed protocol specs accordingly.
8185 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8186 the request was sent by ID and not by nickname. Crashed on
8189 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8191 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8192 now correctly save the received data.
8194 * silc_server_free_sock_user_data now notifies routers in the
8195 network about entities leaving the network.
8197 At the same time implemented functions silc_server_remove_id
8198 and silc_server_send_remove_id to receive and send REMOVE_ID
8199 packets. The packet is used to notify routers in the network
8200 about leaving entities. The ID removed will become invalid in
8203 * Added function silc_idlist_del_server into server. Removes and
8204 free's server entry from ID list.
8206 * silc_server_private_message function now checks, if we are router,
8207 that the destination ID really is valid ID, naturally.
8209 * In router when NEW_ID packet is received (for new client) the
8210 hash of the Client ID is saved in the ID Cache but the
8211 client->nickname is set to NULL, instead of putting the hash
8214 IDENTIFY command now also checks that client->nickname must be
8215 valid. If it is not if will request the data from the server who
8216 owns the client. Added new function
8217 silc_server_command_identify_check.
8219 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8220 to set the command to already allocated Command Payload.
8222 * Tested private message sending in router environment with two
8223 routers, two servers and two clients. Fixed minor bugs and now
8226 * Fixed segfault from client's NAMES command. Used to crash if
8229 * Forwarded packets must not be routed even if it is not destined
8230 to the receiver. Changed server code comply with this.
8232 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Added `require_reverse_mapping' boolean value to ServerParams
8235 structure. If TRUE (not default) the server will require that
8236 the connecting host has fully qualified domain name.
8238 If the reverse mapping is not required and hostname could not be
8239 found the IP address is used as hostname.
8241 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8243 * Implemented version string checking to both client and server.
8244 The check is incomplete currently due to the abnormal version
8245 strings used in development version of SILC.
8247 * Changed all command functions in server to use the new
8250 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8252 * Changed char *data to unsigned char *data in ID Cache system to
8253 support binary data as ID Cache data. Changed code to support
8254 binary data in lib/silccore/idcache.c.
8256 * Renamed silc_server_packet_relay_command_reply to
8257 silc_server_command_reply as it is normal packet receiving
8258 function. Rewrote the function to accept command replys for
8259 servers and not only for clients.
8261 * Mark remote router always as registered server if we are connecting
8262 to it. Otherwise, commands sent by the router to us are ignored.
8264 * All ID List find routines now returns the ID Cache Entry pointer
8265 as well if requested.
8267 * WHOIS command works now in router environment, tested with two
8268 routers, two servers and two clients.
8270 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8271 in router environment (as it is almost equivalent to WHOIS) but
8272 hasn't been tested thoroughly. Added new functions:
8274 silc_server_command_identify_parse
8275 silc_server_command_identify_send_reply
8276 silc_server_command_identify_from_client
8277 silc_server_command_identify_from_server
8279 * Disabled route cache adding because adding two different ID's with
8280 same IP replaces the old cache entry thus giving wrong route.
8281 The entry->router->connection is always the fastest route anyway
8282 so route cache may not be needed. Of course, new routes maybe
8283 established after receiving the ID when the entry->router->connection
8284 might not be anymore the most optimal.
8286 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8288 * Add route cache for received ID for fast routing.
8290 * Added silc_server_packet_route to route received packet on router
8291 that is not destined to us.
8293 * Renamed silc_server_get_route to silc_server_route_get.
8295 * Added id_string and id_string_len fields into SilcServer to
8296 include encoded ServerID for fast comparing without excess
8297 encoding of the ID's.
8299 * Cleaned up WHOIS command on server side. Added following static
8302 silc_server_command_whois_parse
8303 silc_server_command_whois_check
8304 silc_server_command_whois_send_reply
8305 silc_server_command_whois_from_client
8306 silc_server_command_whois_from_server
8308 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8309 arguments in command replies. All command functions should be
8310 updated to use this macro.
8312 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8314 * Minor typo fixes on command reply handling on server.
8316 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8318 * Added silc_server_command_add_to_channel internal routine to add
8319 the client to the channel after router has created the channel and
8320 sent command reply to the server.
8322 * Added generic silc_server_send_command to send any command from
8325 * Use static buffer with ID rendering instead of duplicating data.
8327 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8329 * Fixed a channel user mode bug when joining to a channel server gave
8330 everybody channel founder rights, oops.
8332 * We mark ourselves as the router of the incoming server connection
8333 if we are router ourselves. This way we can check in some packet
8334 sending functions whether it is locally connected server. For
8335 incoming router connections we put NULL.
8337 * For router sending packets locally means now always sending the
8338 packet cell wide; to local clients and local servers. For normal
8339 server sending packet locally means sending it to only local
8342 * Fixed the JOIN command to really work in router environment. If the
8343 channel is created it is always created by the router. Router is
8344 also responsible of making the initial joining to the channel,
8345 sending JOIN notify to the sending server and distributing
8346 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8347 does not exist server doesn't do anything else but forward the
8348 command to the router which performs everything.
8350 * Added silc_server_send_channel_key function to send the Channel Key
8353 * Added silc_server_create_channel_key to create new channel key. The
8354 channel key is now re-generated everytime someone joins or leaves
8355 a channel, as protocol dictates. Note: channel->key_len is the
8358 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8360 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8361 packet_receive.[ch] to separate packet sending and receiving
8362 routines. The server.[ch] now includes everything else including
8363 actual packet processing (writing and reading data) and other
8366 Renamed silc_server_private_message_send_internal to
8367 silc_server_send_private_message. The routine is still though
8368 used only to relay private messages as server does not send
8369 private messages itself.
8371 Renamed silc_server_new_channel to silc_server_create_new_channel
8372 and added new function sicl_server_new_channel that handles the
8373 incoming New Channel packet. Added also new sending function
8374 silc_server_send_new_channel to send New Channel Payload.
8376 * Added new function silc_server_notify to process incoming notify
8377 packet to the server/router. Server may then relay the notify
8378 to clients if needed.
8380 * Added new function silc_server_new_channel_user to process incoming
8381 New Channel User packet. Router will redistribute the packet and
8382 send JOIN notify to its local clients and locally connected servers
8383 if needed. Normal server will send JOIN notify to its local client
8384 on same channel when received this packet. Added also corresponding
8385 sending function silc_server_send_new_channel_user to sent the
8388 * Added boolean route argument to send_notif_to_channel and
8389 packet_send_to_channel functions to attempt to route the packet
8390 if it is TRUE and send only locally if it is FALSE.
8392 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8394 * silc_server_replace_id now broadcasts the received replace ID
8395 packet if it is not broadcast packet already. The router must
8396 broadcast to inform other routers about changed ID.
8398 * Added backpointer to server's router into SilcServer context in
8399 silcd/server_internal.h.
8401 * Fixed silc_server_packet_broadcast to send correct broadcast
8404 * The channel key is now distributed to the local client as soon
8405 as it is received from the router (in router environment) so that
8406 no other packet may be sent for the channel until client has
8409 * silc_server_remove_channel_user now broadcasts the received
8410 Remove Channel User packet if it is not broadcast packet already.
8411 The router must broadcast to inform other routers about removed
8414 * Added users field into SilcPacketContext that is a reference count
8415 of the context. One can increase the reference count by calling
8416 silc_packet_context_dup which is now changed to just increase the
8417 reference count instead of duplicating the data. The reference
8418 count is decresed by calling silc_packet_context_free that will
8419 free the data after the reference count hits zero.
8421 For now on the packet context and everything allocated into it
8422 (including the raw packet from network) must be freed by calling
8423 the new silc_packet_context_free function. Added also new function
8424 silc_packet_context_alloc that must be used now to allocate the
8425 context. This also means that if a routine is asynchronous from
8426 silc_[client/server]_packet_parse_type the packet context must
8427 be duplicated by calling silc_packet_context_dup. Otherwise it
8428 gets free'd after silc_[client/server]_packet_parse_type returns.
8429 Also, one must remember that if packet is duplicated then its
8430 reference count must be decresed by calling the free function as
8431 many times as it was duplicated.
8433 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8434 from both client and server.
8436 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8438 * Made joining to a channel working in router environment.
8440 * Cleaned up JOIN command on server side and create function
8441 silc_server_command_join_channel internal routine to make the
8444 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8446 * Changed silc_command_pending list to SilcDList. Also, added
8447 `ident' field to SilcServerCommandPending structure to identify
8448 the reply and to call correct callback.
8450 Added silc_server_command_pending_check function to replace the
8451 corresnponding macro. The silc_command_pending list is not
8454 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8455 to set identifier to previously allocated Command Payload. It
8456 is used to set identifier for command when resending Command
8459 * Added silc_command_payload_encode_payload to encode Command
8460 Payload buffer from SilcCommandPayload structure.
8462 * Added silc_argument_payload_encode_payload to encode Argument
8463 payload buffer from SilcArgumentPayload structure.
8465 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8467 * Changed WHOIS command to support router connection on server side.
8468 The whois request is always sent to router unless the server is
8469 standalone server. After server has received the reply from the
8470 router will it send the reply to the client.
8472 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8473 broadcast received broadcast packet. The function is used only
8474 by router. The broadcast packet is always sent to the router's
8477 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8478 render given ID to printable string, for log files for example.
8480 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8482 * Made basic router to router connections working. At least they
8483 can now connect to each other but nothing really works the way
8484 they are supposed - yet.
8486 * Added new initiator token to RouterConnection configuration
8487 file in silcd/serverconfig.[ch]. It is used to tell whether we
8488 are the initiator to the remote router or whether we'll expect
8489 the other end to connect.
8491 * Moved registering of listener task to silc_server_init, hence
8492 the server starts listenning as soon as it is run, even if it
8493 does not have connections to other routers. Let's see how well
8496 * Changed default connection retry timeouts for more suitable in
8499 * Removed cipher and such arguments from silc_idlist_add_client
8500 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8501 Added new function silc_idlist_add_data to add the keys and stuff
8504 * Added SilcIDListData structure and added it to SilcClientEntry
8505 and SilcServerEntry as their first field in the structure. This
8506 way we can explicitly cast the ID entries to the SilcIDListData
8507 structure and get common data for the entries. In past, we had
8508 to first check what type of connection it is and then cast it to
8509 correct ID entry type. Now, we can directly cast the opaque
8510 pointer to the SilcIDListData (no matter what ID entry it actually
8511 is) and get the data needed.
8513 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8515 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8516 in some circumstances even if threre were timeout tasks, though not
8517 IO tasks, but tasks anyway. Now fixed.
8519 * Defined SilcServerConnection structure to hold connection specific
8520 stuff about directly connected servers and routers. The definition
8521 is currently in silcd/server_internal.h. I thought about having
8522 a bit more important role fro this struct but for now it is used
8523 only when connecting to other server (or router actually).
8525 * Added connecting retry support in server when connecting to
8526 router(s). The retry feature implement exponential backoff
8527 algorithm. Also, added SilcServerParams structure to hold default
8528 parameters for server. For now, it include these retry settings
8529 and are hard coded. After server is moded to be as Silc Server
8530 Library this structure will be more important.
8532 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8534 * Changed client librarys channel->clients table to SilcList and
8535 changed code accordingly.
8537 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8539 * Changed client's channel table to SilcList and changed code
8540 accordingly. Also changed SilcChannelClientEntry to include back-
8541 pointer to the channel so that client entry can use that structure
8542 as list as well and we have fast cross-reference to the channel.
8543 This change dramatically decreased the complexity of channel
8544 handling with client entry and vice versa (removed one extra
8545 loop when searching for channel entry from many functions).
8547 * Changed server->sim from table to SilcDList and changed code
8550 * NAMES command can now be used from user interface. It will show
8551 the user list on the channel, neatly.
8553 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8554 Code now saves realname of the user if it becomes available.
8556 * Renamed configure.in to configure.in.pre and made ./prepare
8557 script to automatically add correct version string to
8558 configure.in which it creates from configure.in.pre.
8560 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8562 * NAMES command reply now shows users mode with the nickname when
8565 * Moved silc_client_ch[u]mode[_char] functions from
8566 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8567 place sucks, they are utility functions and should be in some
8570 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8572 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8575 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8579 * Added TRQ (efficient deque and list library) into lib/trq. This is
8580 a very good list library that is currently used in the SILC. Defined
8581 SilcList API over the library because I didn't like the API very
8582 much. See lib/trq/silclist.h for the API and examples of how to
8583 use the API. Fixed various places in the code to use the new
8584 SilcList API. The SilcList is meant for lists that has a structure
8585 already defined as a list. It is not suitable to add just some
8586 context to the list (in TRQ, the context is the list actually).
8588 So, I defined SilcDList that can be used for the purpose where
8589 predefined list structure does not exit. This can be used as
8590 such list. Now some context just can be added to the SilcDList.
8591 Currently this list is not used in the SILC just yet, though there
8592 are a lot places where this can replace dynamically allocated
8593 tables and I will fix these places, later, to use SilcDList.
8594 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8595 and use TRQ internally).
8597 Also fixed some annoying warning messages that the original TRQ
8598 code generated. Also minor changes to TRQ's Makefile.in.
8600 * Added support for querying by Client ID to both WHOIS and
8601 IDENTIFY commands into server, as required by the protocol.
8603 * Removed method function pointers from SilcBuffer structure. They
8604 weren't used to anything and just increased the context size for
8605 no good reason. This change also made silc_buffer_alloc and
8606 silc_buffer_free functions inline functions.
8608 * Disabled command flooding detection support until it's fixed so
8609 that it accepts commands in but does not execute them more than once
8612 * Added silc_net_localhost(), to return local hostname, into
8613 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8614 that must be initialized before calling silc_client_init.
8616 * Added new function: silc_server_send_notify_on_channels to send
8617 notify messages to all channels client has joined. It is assured
8618 that the message is sent only once per client.
8620 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8621 lib/silcutil/silcutil.[ch] as silc_format function. The new
8622 function is generic and is used by server as well, not only by
8623 the logging routines.
8625 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8626 the provided version string was not acceptable. Added new function:
8627 silc_ske_check_version into lib/silcske/silcske.h. The function
8628 must be implemented by the application (client or server) and it
8629 does not reside in the SKE library. The function checks the version
8630 string remote end sent.
8632 * Added back pointers (to opaque context and to SilcSocketConnection)
8633 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8635 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8636 duplicate packet context structure.
8638 * Changed `notify' client operation to send same arguments as client
8639 receives from server except for ID's. ID's are mapped to correct
8640 ID entry and that is returned. Also, if channel entry is not sent
8641 by server but the notify is for channel the channel entry is sent
8642 to application (otherwise application doesn't know that it is for
8643 channel (library gets it from packet's Destination ID)).
8645 * Added silc_client_remove_from_channels into client library to
8646 remove a client from all channels it has joined to. Used when
8647 received SIGNOFF notify from server. Added also new function
8648 silc_client_replace_from_channels to replace old ID entry with
8649 new ID entry on all channels. Used when received NICK_CHANGE
8652 * Fixed ID Cache list handling in silc_idlist_get_client in
8653 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8654 to get (or query) client by ID.
8656 * Updated TODO list.
8658 * Added connection authentication status message defined by the
8659 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8660 support for these into the code in client and server side.
8662 * Added generic function silc_client_send_command to send any command
8663 with variable argument list. Application should use this function
8664 to send commands if the command functions provided by the library
8665 does not suite for the application's user interface needs.
8667 * Added new `failure' client operation. Application is notified about
8668 received failure packet if client is executing a protocol. In this
8669 case the protocol's execution has failed.
8671 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8672 is required by the protocol.
8674 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8675 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8678 * Added status flag to SilcSKE object to indicate realtime status
8679 of the SKE protocol.
8681 * Application receives now exactly same command reply arguments as
8682 the library receives from server. However, if ID is received the
8683 corresponding ID entry is returned to the application (eg. Client
8684 ID is mapped to correct SilcClientEntry entry and that is returned).
8685 Changed command_reply client operation due to this change.
8687 * Changed all ID's in commands and in command replys as ID Payloads.
8688 Change affected both client and server side codes.
8690 All ID's sent in SILC network (with execption of ID's in SILC
8691 Packet header) are sent in ID Payload to support variable length
8694 * Server now notifies nick changes and notifies all clients on
8695 the channels about the new nickname (about the new Client ID,
8698 * Implemented CMODE command to change channel modes. Supports all
8699 channel modes defined by the protocol specs except ban and invite
8700 lists. (Also, private channel key mode is supported but support for
8701 setting private channel key in client is missing, thus, this mode
8702 has no effect on client side (except that server requires that the
8703 client uses private channel key and normal channel traffic does not
8706 Also, invite mode works per se, but INVITE command does not work
8707 yet correctly, so you can set channel as invite only channel but
8708 inviting clients to the channel does not work (it is yet to be
8709 thought what's the best way to do it).
8711 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8712 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8713 Implemented CUMODE command to change user's mode on the channel.
8714 Supports all modes defined by the protocol specs.
8716 * Added NAMES command reply to return users modes on the channel.
8718 * Removed unnecessary and slow ciphers from lib/silccrypt.
8720 * Set SO_KEEPALIVE option to connection sockets by default.
8722 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8724 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8725 redefined the Notify Payload into protocol specs.
8727 * Added silc_id_payload_parse_id to get ID directly from raw
8730 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8732 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8733 accept searching by Client ID as well.
8735 * Added support for LEAVE and SIGNOFF notify types in client library.
8737 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8738 to parse ID Payload from raw data.
8740 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8742 * Added flags parameter into silc_ske_assemble_security_properties
8743 function in lib/silcske/silcske.[ch].
8745 * Changed notify client operation to fit better for notify messages
8746 sent by server. The notify payload received from server is now
8747 passed to the application (after parsing it to SilcNotifyPayload).
8748 It is application's responsibility to retrieve the arguments
8749 from the payload and show the message the way it wants. The message
8750 sent by server is implementation specific.
8752 * Changed public keys to comply with the protocol specification.
8753 Old public keys are not supported anymore and are not compatible.
8755 * Removed nickname from Channel Payload as the latest draft removed
8756 it. The client must resolve the nickname from the NAMES command
8757 reply received when it joined the channel.
8759 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8761 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8763 * Fixed some errors in protocol specification drafts.
8765 * Created lib/silccore/silcnotify.c to implement Notify Payload
8766 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8767 generic payloads described by protocol specifications. The file
8768 includes implementations for ID Payload and Argument Payload.
8770 * Changed Command Payload implementation to use the new Argument
8771 Payload. Changed command_xxxx_payload to command_payload_xxxx
8772 to comply with SILC coding conventions.
8774 * Added suppport for Argument Payload handling in Notify Payload
8775 implementation as protocol requires it. Added the new support
8776 into server and client lib as well.
8778 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8780 * Added support for multiple nicknames on same channel. [n] is
8781 added locally to the nickname if there are more than one same
8782 nicknames on the channel.
8784 * Server now sends all nicknames that matched WHOIS request.
8785 Client also shows the list received from server.
8787 * Added TOPIC command to client side. User can now set and show
8788 current topic on channel.
8790 * Added MOTD command to client and server. Also, server sends the
8791 motd when client connects to the server.
8793 * Changed version strings to comply ISO 8601.
8795 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8797 * Fixed protocol error handling in client library. It should now
8798 cope even if the SKE fails for some reason.
8800 * Made new protocol specification drafts for submitting to IETF.
8802 * Implemented TOPIC command to server in silcd/command.c.
8804 * Added two new notify types into lib/silccore/silcnotify.h:
8805 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8806 notify nickname change and topic setting/change on a channel.
8808 * API change of command_reply operation in client library. The
8809 application gets now the status type received from server as well.
8811 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8813 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8815 * Cras fixed and optimized the packet handling even further and
8816 it should work now. Minor change to the prototype of function
8817 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8819 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8821 * Added new function into lib/silcutil/silcschedule.[ch]:
8822 silc_schedule_with_fd to select() a specified fd. The function
8823 returns after timeout expires or data arrives or goes. The
8824 function is used by packet routines to wait that all data is
8825 received from network.
8827 * Fixed data reading from network in lib/silccore/silcpacket.c.
8828 The code now assures that all data is read from the fd and then
8829 continues packet processing. This was a bug fix since the code
8830 used to drop some data in some circumstances.
8832 * Added new function into lib/silcclient/client.[ch]:
8833 silc_client_start_key_exchange to start key exchange after
8834 connection has been established to server. The code internally
8835 now uses this funtion but its main purpose was to provide it
8836 for applications that perform their own connecting. After
8837 application has created a connection it merely calls this
8838 function to start the key exchange between client and server.
8839 The library takes care of everything else after that.
8841 Updated also lib/silcclient/README to explain the usage of
8844 * Do not send to application information that connection has
8845 been established. Application gets notified it by connect
8848 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8850 * Applied cras's patch to add silc_schedule_one function. The
8851 function runs scheduler once and returns.
8853 * Fixed the scheduler after cras messed it up. The timeout
8854 handling works now as it's supposed to work.
8856 * Added into lib/silccore/ silcnotify.h to include notify
8857 message types support. Changed silc_server_send_notify*
8858 functions, in server.[ch], to support those new notify types.
8859 Added the support for the notify types into client library,
8860 as well. Added new notify client operation into ops.h in
8863 * Changed silc_server_packet_send_to_channel to send normal
8864 packets instead of just channel message packets. The function
8865 is now used to send the notify packets to channels. It is not
8866 used to send channel message packets anymore, as server never
8869 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8870 va_arg()s as it seems to require it nowadays. I guess, if SILC
8871 is compiled with older va_arg() the new code should work anyway.
8873 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8875 * Splitted core library. Core library (lib/silccore) includes
8876 now only SILC protocol specific core (and common) components.
8877 Created new utility library (lib/silcutil) that includes more
8878 generic purpose stuff. The stuff for util library was taken
8879 from the old core library. This was minor and easy split.
8881 * Created SILC Client Library (lib/silcclient) that includes
8882 implementation of the SILC client without user interface. This
8883 was major move from silc/ directory. The code has been changed
8884 so that it is transparent towards the user interface. The
8885 silc/ directory includes now the same user interface as before
8886 and it uses the new client library. Read lib/silcclient/README.
8887 Basicly, the client library performs everything else related
8888 to SILC except user interface handling. Also, configuration
8889 files are considered to be part of user interface and library
8890 does not handle them.
8892 This change also changed a lot of structures, function naming etc.
8893 Most important change was that SilcClientWindow object was
8894 renamed to SilcClientConnection in the client library. Created
8895 also new file lib/silcclient/ops.h. Also added new files
8896 silc/local_command.[ch] and silc/client_ops.[ch].
8898 All these changes were made to make it easier for user interface
8899 designers to create what ever user interface for the SILC client
8902 It is also expected that the server will be moved to lib
8903 directory as well and SILC Server Library will be created;
8904 sometimes in the future.
8906 * Removed Local commands from lib/silccore/silccommand.h as
8907 they are application specific and new client library does not
8908 handle any of those anymore.
8910 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8911 old client implementation in silc/.
8913 * Added support for callback functions in SILC_LOG_* macros.
8914 Application can now set its own callbacks that will be called
8915 instead of using the default functions that will always print
8916 the debug messages to stderr (or stdout). Also, debugging can
8917 now be disabled by setting silc_debug to FALSE and re-enabled by
8918 setting it to TRUE. Note, that logging will still work even
8919 if debugging is disabled.
8921 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8922 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8923 silc_log_reset_debug_callbacks.
8925 * To enable debugging in silc client one must give now -d
8926 option on command line.
8928 * Changed silc_schedule_init to automatically allocate task queues
8929 if they are not allocated before calling it.
8931 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8933 * Added GMP 3.1 into math library.
8935 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8937 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8938 a channel in SILC network. The packet is used by servers and
8939 routers to notify other routers that user has left a channel.
8940 This little feature was missing until now. Added the feature
8941 to protocol specification as well.
8943 Added functions: silc_server_send_remove_channel_user and
8944 silc_server_remove_channel_user into server.[ch].
8946 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8947 lib/silccore/silcpacket.h. However, they are not implemented
8950 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8952 * Fixed joining to a channel and sending channel messages
8953 between server and router. The channel message sending should
8954 now work inside a cell.
8956 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8958 * Fixed the private message sending between server and router.
8959 The private message sending should now work inside a cell.
8961 * Added silc_server_replace_id into server.[ch] to replace
8962 existing ID in the SILC network.
8964 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8965 and silc_idlist_replace_server_id into idlist.[ch] in server.
8967 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8969 * Fixed the server to server connections. Server can again now
8970 connect to router. Router to router connections probably does
8973 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8975 * Added dynamic protocol registering support. Now protocols can
8976 registered and unregistered on the fly. Patch by cras.
8978 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8980 * Added lib/contrib directory to hold routines that some platforms
8981 don't have but are needed by SILC.
8983 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8984 into lin/contrib to provide getopt() and getopt_long() for
8985 those who don't have it.
8987 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8989 * Added AWAY command to client. When away message is set and
8990 client receives a private message packet the client automatically
8991 replies to the sender with the away message.
8993 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8994 bug seemed to be the cause of recent problems when compiling
8997 * Added version detection support to SKE protocol specification
8998 and added the new changes to the SKE implementation as well.
8999 There were other minor changes in the SKE protocol as well.
9001 Many changes in lib/silcske/silcske.[ch] and in
9002 lib/silcske/payload.[ch].
9004 * Added ^U functionality, clear input line. Patch from cras.
9006 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9008 * Mainly small bugfixes on core library. Fixed some debugging
9009 logging and buffer overflow in silclog.c.
9011 * Updated config.sub and config.guess on the distribution tree.
9013 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9015 * Added command lagging support in server. Client may execute
9016 commands now only once in two seconds.
9018 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9020 * Optimized packet reception. MAC computation and checking is now
9021 also more optimized. A lot previously duplicated code is now
9022 used as generic by both client and server.
9024 * Fixed key pair generation in clientutil.c
9026 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9028 * Added into lib/silccore/silcbufutil.[ch] new function;
9029 silc_buffer_realloc.
9031 * Moved generic packet sending/encryption functions to
9032 lib/silccore/silcpacket.[ch] from client and server. Some
9033 rewriting of the functions.
9035 * Moved all generic packet reception/decryption functions to
9036 lib/silccore/silcpacket.[ch] from client and server. The
9037 packet processing is now much cleaner in both client and server.
9038 These were major changes in both client and server.
9040 * Created many common functions in server to do packet sending.
9041 Previously code were duplicated a lot, this has been removed
9044 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9046 * Rewrote major parts of the ID cache system. Don't know
9047 whether it is better now or not but at least the API is more
9050 * Major rewrite on ID cache stuff on client because of the ID
9051 cache API changes. Added idlist.c to client.
9053 * Also major rewrite on ID cache stuff on server as well.
9054 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9055 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9056 in hand, instead they are all put into the ID cache system now.
9057 All server_idlist_* routines uses ID cache now instead of
9058 traversing its own lists (those lists does not exist anymore).
9059 SilcIDList though still exists. Also, SilcXXXEntry's are
9062 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9064 * Finally made the SKE implementation compliant to the protocol
9065 specification. All mp integers are now binary encoded as
9066 opposed being HEX encoded.
9068 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9071 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9072 functions: silc_[encode/decode]_pem. Also added function
9073 silc_encode_pem_file to PEM encode with newlines ('\n') for
9076 * SILC public keys are now encoded either PEM or binary. Same
9077 option is for private keys as well. By default private keys
9078 are binary encoded and public keys PEM encoded. Silly HEX
9079 encoding were removed.
9081 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9082 function to create fingerprints.
9084 * Fixed a bug in SHA1; does not change the original data anymore.
9086 * Partly implemented INFO command on client and server side.
9087 Fixed CLEAR command. Changes to SERVER command; show current
9088 server(s) when giving command without arguments. Added
9089 VERSION command to client.
9091 * Added check to server that unregistered connections cannot
9092 execute commands (unless it is specificly allowed).
9094 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9096 * Fixed screen refresh.
9098 * Fixed channel joining bug from client. On some circumstances
9099 client tried to join to a channel it had already joined.
9101 * Added public key verification process into client's protocol.c.
9102 The client now verifies the public key from user and saves
9103 it into ~./silc/serverkeys/ directory.
9105 Added into: clientutil.[ch]: silc_client_verify_server_key.
9107 * Changed SKE protocol's silc_ske_initiator_finish function
9108 to accept callback function that verifies the received public
9109 key. Removed old silc_ske_verify_public_key function.
9111 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9113 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9114 silc_pkcs_private_key[_data]_set.
9116 * Made the password and public authentication more cleaner in
9117 server's protocol.c.
9119 * Removed historic and obsolete protocol `channel_auth' from
9120 both client and server.
9122 * Removed wrong way of sending command status messages from
9123 server to client in server's command.c. The old way violated
9124 protocol specification.
9126 Changes to silccore/silccommand.[ch]: removed
9127 silc_command_encode_status_payload -> not needed anymore,
9128 changed silc_command_encode_payload_va to accept extra
9129 argument on variable argument list. The argument type must
9130 now be provided to the function. Also, added new function:
9131 silc_command_encode_reply_payload_va which is same as
9132 normal command_encode_payload_va except command status type
9133 is provided as extra argument.
9135 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9137 * Added ~./silc directory handling. The directory includes the
9138 public and private keys for the client.
9140 Added silc_client_check_silc_dir, silc_client_create_identifier
9141 and silc_client_load_keys.
9143 * Implemented SILC protocol compliant public key. Added public
9144 and private key saving to and loading from files.
9146 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9147 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9148 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9149 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9150 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9152 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9153 silc_pkcs_load_[public/private]_key.
9155 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9157 * Added silc_server_get_route (route.[ch]) to get connection
9158 data for the fastest route for given ID.
9160 * Implemented INVITE command on client and server. The command
9161 were re-defined in the SILC Protocol Specification and the
9162 implementation now complies with the specification.
9164 * Implemented PING command on client and server.
9166 * Implemented NAMES command on client and server. The server side
9167 supports currently only normal server not router server yet.
9168 Some changes to NAMES definition in SILC protocol specification.
9170 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9172 * Implemented LEAVE command on client and server.
9174 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9175 again. This change was made to the protocol as well. Server
9176 should not violate the protocol specification anymore.
9178 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9180 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9181 was tested. SOCKS4 was not but should work anyway.
