1 Sun Oct 6 16:48:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Don't swtich to become primary router if we are backup if
4 decryption error has occurred. Affected file silcd/server.c.
6 * Fixed a bug in backup router IP address comparison in
7 silc_server_backup_get.
9 Save now also the port of the server/router and use that
10 in comparison as well. Affected file silcd/server_backup.c.
12 * Normal server now reconnects to backup router automatically
13 if connection is lost to it. Affected file silcd/server.c.
15 Thu Sep 26 13:51:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
17 * If packet processing fails (like integrity check fails)
18 the connection is closed now. Affected files are
19 lib/silccore/silcpacket.c and silcd/server.c.
21 Mon Sep 23 10:59:39 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
23 * Fixed double free in RSA public key set function
24 silc_rsa_set_public_key. Affected file lib/silccrypt/rsa.c.
27 Sun Sep 22 14:54:05 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
29 * Rewrote WHOIS, WHOWAS and IDENTIFY commands in the server.
30 Added server_query.[ch] which provides one interface for
31 querying information using all three commands.
33 * Changed all "typedef unsigned char" in core library to
36 Sat Sep 21 21:36:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Added silc_strncat into lib/silcutil/silcstrutil.[ch].
40 * Renamed silc_server_get_client_resolve to
41 silc_server_query_resolve and moved to server_query.[ch].
43 Wed Sep 18 18:28:04 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Resumed client packet handling from server put the resumed
46 client on wrong list on router and caused the client not
47 be present on the network anymore. Now fixed to put the
48 client to correct list. Affected file silcd/packet_receive.c.
50 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
52 * Various cleanup in error message output in config parsing code
53 and in server init code. Fixed error log files containing
54 too many newlines ('\n') in some situations. Affected files are
55 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
57 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
59 * Use the reverse lookupped hostname in client internals
60 instead of one user provided us as remote server name.
61 Affected file lib/silcclient/client.c.
63 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
65 * Added 'app_context' to silc_schedule_init. It is an
66 application specific context that is delivered to application
67 in task callback functions. Affected files are
68 lib/silcutil/silcutil.[ch].
70 * The hb_context in SilcSocketConnection is not freed
71 automatically anymore (application must free it). Freeing
72 it automatic is inconsistent. Affected files are
73 lib/silcutil/silcsockconn.[ch].
75 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
77 * Added support for removing explicitly added client connections
78 in rehash and closing the client connections if they were
79 unconfigured in the rehash. Affected file silcd/server.c.
81 * Added support for aborting automatically pending commands
82 that never receives the reply (to avoid memory leaks).
83 Added also silc_server_command_pending_timed to set the
84 specific timeout for pending command. Affected files are
85 silcd/command[_reply].[ch].
87 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
88 specs and lib/silccore/silcstatus.h.
90 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
92 * Changed the silc_get_time to accept time value as argument
93 or if zero is sent return current local time. Affected
94 file lib/silcutil/silcutil.[ch].
96 * Added STATS command to client library and Irssi SILC client.
97 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
99 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Assure that channel key is set before sending it. May
102 crash server otherwise. Affected file silcd/packet_send.c.
104 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Assure that endless loop cannot happen with detached client
107 resolving on normal server. Added idlist status
108 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
109 silcd/idlist.h and silcd/packet_receive.c.
111 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
113 * Incoming file transfer request cannot use same session as
114 the sending session. This can happen when sending file to
115 yourself. Crashed the client on quit. Affected file
116 lib/silcclient/client_ftp.c. Bug #24.
118 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
120 * Implemented the draft-riikonen-precense-attrs draft and
121 the Attribute Payload into the lib/silccore/silcattrs.[ch].
123 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Distribute the SERVER_SIGNOFF notify also to local backup
126 routers from the primary router. The backup router may not
127 have the signing of local server directly connected and need
128 to know about the signoff. Affected file silcd/server_util.c.
130 * Use the primary router as the origin of the locally connected
131 server when it is disconnecting from the backup router since
132 that's where it really is coming from. Now the clients from
133 the disconnecting server are removed correctly and "shadow"
134 clients are not left to the backup router. Affected file
137 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
139 * If normal server is standalone and found existing but disabled
140 channel, do not re-create the channel since it creates
141 duplicate same channels. Affected file silcd/server.c.
143 * Added anonymous client connections support to server. New
144 "anonymous" configuration option to ConnectionParams section
145 added. If set to true, the username and hostname information
146 of the client will be scrambled and anonymous user mode is
147 set automatically to the user. Affected files are
148 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
150 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
152 * In JOIN notify handling, mark that the cache entry of the
153 client cannot be expired. Can cause crashes on normal
154 server (asserts client->channels). Affected file is
155 silcd/packet_receive.c.
157 * From now on distribution versions are used as protocol versions
158 instead of by default using the Toolkit base version as protocol
159 version. Affected file prepare.
161 * Do not set the locally resolved hostname for local client
162 entry but take what server sends. This way the real hostname
163 is showed in WHOIS for yourself. Affected file is
164 lib/silcclient/idlist.c and lib/silcclient/client.c.
166 * Resolve local info with IDENTIFY when connecting to server.y
168 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
170 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
171 for implied search (not needed on platforms which has native
172 pthreads library). Use --without-pthreads to disable threads.
173 Affected file is configure.in.pre
175 * Fixed --with-iconv on platforms which need to bypass (broken)
176 native iconv(). Affected file is configure.in.pre
178 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
180 * Moved -C option parsing in Irssi SILC client at same time
181 as other options. The UI was initialized earlier and caused
182 problems on command line. Bug #16. Affected file is
183 irssi/src/silc/core/silc-core.c.
185 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
187 * Added global variable silc_log_timestamp that tells silclog
188 wether to print or not the timestamp in the logging files.
189 Affected file lib/silcutil/silclog.[ch].
191 * Added silcd configuration option Timestamp in the Logging
192 section. Affected file silcd/serverconfig.[ch],
193 doc/example_silcd.conf.in.
195 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed fingerprint checking to check for entirely empty
198 fingerprint instead of two first bytes when determining
199 if it is set. Bug #18. Affected file silcd/command.c.
201 * Fixed duplicate PKCS name registering to not allow it.
202 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
204 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
206 * Conditionalize non-gcc compiler optimizations for various
207 platforms, enable those commented out. Cleanups.
208 Affected file lib/silcmath/mpi/configure.in
210 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
212 * silc_rng_exec_command() left zombie processes if command
213 didn't generate any output. Affected file
214 lib/silccrypt/silcrng.c
216 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
218 * Rewrote iconv checking, introduce --with-iconv for systems
219 which rely on libiconv. Check if iconv() provided by libc
220 is good enough, otherwise demand libiconv. Affected file
223 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
225 * Search for ldopen() also in libc. This enables SIM support
226 on *BSD systems. Based on patch from Alex Zepeda. Affected
227 file configure.in.pre
229 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
231 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
232 This fixes prepare on *BSD systems. Affected file
235 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
237 * More fixed for not having purge timeout for global clients
238 that are on channel. Affected files silcd/command_reply.c
241 * Fixed the rekey protocol to work with backup router connections.
242 Rekey packets are now allowed on disabled connections as
243 well. Affected files silcd/packet_send.c and server.c.
245 * Do not switch to be as backup router when shutting down and
246 closing the primary connection. Affected file silcd/server.c.
248 * Fixed memory leaks in backup router deleting. Added
249 silc_server_backup_free to free all data during shutdown of
250 server. Affected files silcd/server_backup.[ch].
252 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
254 * Do not process commands if the sock->user_data is NULL.
255 Affected file silcd/command.c.
257 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
259 * Fixed buffer overflow and security problems (loosing bits
260 in CFB encryption) in SILC RNG. Problems reported by
261 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
263 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
265 * Added yet more checks that client is not expired on global
266 list if it is on channels. Affected file is
267 silcd/command_reply.c.
269 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
271 * Merged c0ffee's MIME signal patch which adds support for
272 sending also MIME messages in Irssi SILC Client, and handling
273 received MIME messages in a signal (and perhaps doing something
274 to non-textual MIME messages).
276 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
278 * Fixed pending command deletion in server and client library
279 to check the whole list instead of breaking after first found.
280 The affected files are silcd/command.[ch] and
281 lib/silcclient/command.[ch].
283 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
285 * Return NO_SUCH_CHANNEL error in USERS for channel that is
286 secret or private, otherwise it's possible to find out
287 whether a secret channel exists or not. Affected file
290 * If CMODE change fails during the mode setting, assure that
291 the old mode mask is set for the channel back. Affected
292 file silcd/command.c.
294 * Fixed passphrase saving on +a channel on normal server
295 after successful JOIN command. Affected file silcd/command.c.
297 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
299 * Remove server/router operator privileges in DETACH command,
300 since it's possible to resume to server where these
301 privileges would not be allowed for the client. Affected
302 file silcd/command.c.
304 * Do not set to wait for backup in rehash of the server.
305 Affected file silcd/server.c.
307 * Do not check listener sockets when counting how many
308 socket connections we have. Affected file is
311 * Do not announce disconnected clients that are remaining
312 in history (for WHOWAS). This is because SIGNOFF notify
313 for these has been sent earlier already. Affected file
316 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
318 * Buffer overflow with CUMODE command's mode->mode character
319 conversion. Reported by Ville Räsänen. Affected file
320 lib/silcutil/silcutil.c.
322 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Allow heartbeat packets to go disabled connections anyway.
325 Affected files silcd/server.c and silcd/packet_send.c.
327 * Do not broadcast New Channel packets with List flag set
328 in the packet to backup routers. The router must check
329 for the correctness of the packets before sending them.
330 It is possible that router will have enforce Channel ID
331 change and this would cause desync in the backup router.
332 Affected file silcd/packet_receive.c.
334 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
335 are handled in list parsing. They are not list packets
336 anymore. Affected file silcd/packet_receive.c.
338 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
340 * Stop waiting for backup router through the timeout, not
341 directly after backup router has arrived. Affected file
344 * Do not re-create channel keys and send them when removing
345 clients in server shutdown. Affected files are
346 silcd/server_internal.h and silcd/server_util.c.
348 * Notify distribution to backup routers was missing from
349 the silc_server_send_notify_dest function which caused
350 desyncing problems with backup router. Affected file is
353 * The client's channel removing was working wrong on
354 backup router. It assumed that it doesn't know global
355 information but backup router does know. For this reason
356 it could remove channel when it wasn't supposed to do that.
357 Affected file silcd/server.c and silcd/server_util.c.
359 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
361 * Stop for a couple seconds after badkup router has become
362 primary router. Affected file silcd/server.c.
364 * Added silc_server_remove_servers_by_server, which is used
365 to remove servers originated from some other server. Also
366 clients of those servers can be removed too. Affected file
367 silcd/server_util.[ch].
369 * When removing clients after a server has signed of remove
370 also all servers behind that server (unless they are known
371 to be available locally), and send SERVER_SIGNOFF for each
372 of the server separately. Also the signed off clients are
373 sent now separately per signed off server. The affected files
374 are silcd/server.c and silcd/server_util.[ch].
376 * All servers added with silc_idlist_add_server must always
377 have both "router" and "connection" pointers set. Otherwise,
378 bad server entries may be left around in the cache.
379 Affected file silcd/command_reply.c.
381 * Do not create the channel key in NEW_CHANNEL packet
382 processing if the channel is empty. Affected file
383 silcd/packet_receive.c.
385 * Completed backup router support for standalone routers.
386 Supports also servers in the cell that do not use the backup
389 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
391 * Fixed a bug in silc_string_regexify which did not add '^'
392 at the start of each string, and thus the matching was
393 not explicit. For example ban list iikone@*!*@* would
394 match also "priikone", which is wrong, it would have to be
395 *iikone@*!*@* to match also "priikone". Affected
396 file lib/silcutil/unix/silcunixutil.c.
398 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
400 * Enable all local server connections before updating client
401 caches when we've become backup router. Otherwise, signoff
402 packets may not reach the clients. Affected files are
403 silcd/server.c and silcd/server_util.[ch].
405 * Fixed a bug in version string parsing which could crash
406 the program with specially formatted version string.
407 Bug reported and patch provided by Ville Räsänen. Affected
408 file lib/silcutil/silcutil.c.
410 * Handle the disconnection immediately when DISCONNECT
411 packet is received in server. Affected file silcd/server.c.
413 * Primary router now waits a short time (10 seconds) for
414 backup router connection before accepting any other
415 connection (except local). Affected file silcd/server.c,
418 * Fixed a crash in client libary in NICK_CHANGE notify when
419 NICK_CHANGE arrived for client entry we are resolving
420 currently. Affected file lib/silcclient/client_notify.c.
422 * Call the sconn->callback completion even if error had
423 occurred. Start reconnecting always if connection to
424 primary router fails during backup router protocol.
425 Affected files silcd/server.c and server_backup.c.
427 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
429 * Added functions silc_server_send_opers and
430 silc_server_send_opers_notify to send packets stricly
431 to operators. Added macro SILC_SERVER_SEND_OPERS macro
432 to send variable argument notify to operators.
433 Affected files silcd/packet_send.[ch] and silcd/server.h.
435 * Removed UMODE rights checking with UMODE_CHANGE notify.
436 Affected file silcd/packet_receive.c.
438 * Server/router operator now receives notify when network
439 switches to backup router and when it resumes the use of
440 primary router. Affected file silcd/server.c and
441 silcd/server_backup.c.
443 * Fixed the updating of client information after backup
444 resuming protocol is over; update all except local clients
445 to the new primary router. The affected file is
448 * Added support for closing active connections in rehash
449 that were unconfigured by the user. Supports currently
450 closing server and router connections. Affected file
453 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
455 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
457 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
458 is NULL since seems that on some platforms NULL is allowed
459 and on some it's not. Fallback encoding is used instead.
460 Affected file lib/silcutil/silcstrutil.c.
462 * Fixed statistics updating for incoming server connection
463 which could cause problems when re-connecting. Affected
466 * Preliminary backup router support for standalone router
467 added. Affected files in silcd/.
469 * Mark server connections in backup router disabled before
470 and after backup protocol. Affected file is
471 silcd/server_backup.c.
473 * Added support for reconnecting to remote server connection
474 even if the protocol fails, and if the configuration wants
475 us to keep trying to connect anyway.
477 Server connection is not allowed to backup router if
478 backup router does not have connection to primary router yet.
480 Affected file is silcd/server.c.
482 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Added silc_client_udpate_server function to update changed
485 server info. Affected file lib/silcclient/idlist.[ch].
487 * Added check for server entries that are being resolved when
488 notify is received. If being resolved, handle the received
489 notify only after it's resolved so that all notifys are
490 handled in same order as received from the server.
492 Added similar resolver check to channel entries. Every
493 notify that cause resolving of any information that affects
494 channel entry marks the channel entry in waiting state.
495 After whatever resolving is over the waiters are signalled
496 and only then the notifys are handled in the same order
497 as delivered from the server.
499 Affected files are lib/silcclient/idlist.[ch], and
502 * Fixed KILLED notify handling in normal server. Affected
503 file silcd/packet_receive.c.
505 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
506 is locally connected, or was locally connected (but may
507 be detached and connection is not active). Added also
508 SILC_IS_LOCAL for checking this status. Affected files
509 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
510 silcd/server.c and silcd/server_internal.h.
512 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
514 * Don't send or handle TOPIC_SET if topic is already set and
515 is same as being set. Affected files silcd/command.c and
516 silcd/packet_receive.c.
518 * Fixed CMODE change rights checking to work correctly when
519 removing modes by operator. Affected file is
522 * Fixed some handling with New Channel packet in router and
523 fixed some CMODE_CHANGE notify handling in server and router.
524 Affected file is silcd/packet_receive.c.
526 * Changed "disconnect" client operation to include the
527 reason of the disconnection and optional disconnection
528 message. Affected file lib/silcclient/silcclient.h.
530 * Made the compilation of lib/contrib/ stuff conditional.
531 Affected files configure.in.pre, lib/contrib/Makefile.am.
533 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
535 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
536 to the sender of the notify too, to avoid situation where two
537 notifys are in the network at the same time going to oppsite
538 directions. Affected file silcd/packet_receice.c.
540 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
542 * Delete the client from channel even if the cilent->id is
543 NULL. It was possible that client was deleted without
544 removing from channels (theoretically at least). Affected
545 file silcd/server.c and silcd/server_util.c.
547 * Free the client data too when resuming is not successful.
548 Affected file silcd/packet_receive.c.
550 * Merged some code from c0ffee's silc-plugin. Affected files
551 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
553 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
554 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
555 to the primary router connection, the other one returns
556 TRUE if packet must be broadcasted to network.
558 * All notifys that are destined to primary router (to network)
559 are now automatically sent to backup routers even if the
560 router is standalone (and has backup router). Affected files
563 * Added --without-irssi and --without-silcd configuration

1100 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
1101 Updated the protocol specs and code. Affected files are
1102 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
1103 lib/silcclient/client_notify.c, silcd/packet_receive.c,
1104 and irssi/src/silc/core/client_ops.c. Renamed the
1105 SilcCommandStatus to SilcStatus.
1107 * Defined the use of extra WHOIS attributes in WHOIS command.
1108 The <Requested Attributes> (defined in a separate document)
1109 can be used to request additional information about user
1110 not returned by standard WHOIS command. Defined that server
1111 can send WHOIS command directly to client. Client provides
1112 the requested attributes to the server. Updated the protocol
1113 specs. Protocol TODO #4. Implementation is not done yet
1114 (Protocol TODO #24).
1116 * Renamed function silc_client_command_status_message to
1117 silc_client_status_message. Affected files are
1118 lib/silcclient/command_reply.[ch].
1120 Sun Apr 14 21:13:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Changed the WHOIS, IDENTIFY and WHOWAS count arguments to
1123 32 bit integers. Updated the protcol specs and the code.
1124 Affected files are silcd/command.c and

1130 payload would lead to a crash. Affected file is
1131 lib/silccore/silcauth.c.
1133 Sat Apr 13 13:09:24 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1135 * Added detach_disabled and detach_timeout server config
1136 options to the server. Affected files silcd/serverconfig.[ch],
1137 silcd/command.c and silcd/packet_receive.c.
1139 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Added resolve_cmd_ident field to the SilcClientEntry structure
1142 too so that if the entry is for example being resolved so
1143 another command may attach to the same pending command reply
1144 without requiring to resolve the same entry again. Added
1145 support for adding multiple pending commands for one
1146 command idenfier. Affected files lib/silcclient/command.[ch],
1147 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
1149 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1151 * Defined that server receives WHOIS command reply for private
1152 and secret channels too. Updated protocol specs and the
1153 code in server. Affected file silcd/command.c.
1155 * Defined <channel user mode list> argument to WHOIS command
1156 reply for returning user modes on the channels. The
1157 channel list now doesn't include the user mode anymore but the
1158 actual channel mode. Updated protocol specs and the code in
1159 client and server. Affected files are silcd/command_reply.c,
1160 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
1161 and lib/silcclient/command_reply.c.
1163 * Save the channels list in WHOIS command reply in normal server
1164 so that WHOIS always shows joined channels also in normal
1165 server and not just on router. Affected file is
1166 silcd/command_reply.c.
1168 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1174 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1176 * Changed the UMODE's mode mask argument to be optional. If
1177 not provided then the command merely returns the current mode
1178 mask to the client. Updated protocol specs and the server.
1179 Affected file is silcd/command.c.
1181 * Added SILC session detachment/resuming support. It is possible
1182 to detach by closing the network connection and then re-connect
1183 and resume to the old client session. Added DETACHED user
1184 mode that server will set for detached client. Added new
1185 packet RESUME_CLIENT which is used to perform the resuming
1186 process. Added DETACH command. Updated the protocol specs,
1187 core library, client and server. Protocol TODO #22. Very
1188 many affected files around the tree.
1190 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1192 * Changed the CMODE's mode mask argument to be optional. If
1193 not provided then the command merely returns the current mode
1194 mask to the client. Updated protocol specs and the server.
1195 Affected file is silcd/command.c.
1197 * Changed the Killer's Client ID in KILLED notify to be just
1198 any ID payload since router server is allowed to kill as well.
1199 Updated protocol specs, client libary and server. Affected
1200 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
1201 and irssi/src/silc/core/client_ops.c.
1203 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1205 * Added new user modes ANONYMOUS for special anonymous servers
1206 that may set the mode for client, and BLOCK_PRIVMSG which
1207 client may set to block incoming private messages unless the
1208 Private Message Key flag is set (using private keys to protect
1209 private messages). Updated protocol specs and code in client
1210 and server and core library. Protocol TODO #23. Affected
1211 files are lib/silccore/silcmode.h, silcd/server.[ch],
1212 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
1213 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
1215 * Added new channel user mode BLOCK_MESSAGES which the client
1216 may set to itself to tell server not send channel messages.
1217 Other packets such as channel key packets are still sent.
1218 Protocol TODO #23. Updated the protocol specs, client and
1219 server. Affected files are lib/silccore/silcmode.h,
1220 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
1221 lib/silcutil/silcutil.c, silcd/command.c, and
1222 silcd/packet_send.c.
1224 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Redefined the Status Payload to include now two 8 bit fields,
1227 instead of one 16 bit field. This now makes it possible to
1228 send list of errors. Updated the protocol specs and the code
1229 in core library, client library and server. Protocol TODO #1.
1230 Affected files are lib/silccore/silccommand.[ch],
1231 lib/silcclient/command_reply.[ch], silcd/command.c,
1232 silcd/command_reply.c and silcd/packet_receive.[ch].
1234 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1236 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1237 must be handled by the application and should tell the application
1238 that an error message was already printed, and it should print the
1239 config coords (line, filename, ...). Affected files are
1240 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1242 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1243 server config parsing code more readable.
1245 Fixed a bug in the fetch_logging() config callback.
1247 Affected files is silcd/serverconfig.c.
1249 * Drop root privileges when started in foreground. Don't drop them
1250 if debugging also. Affected file is silcd/silcd.c.

1255 for setting various presence information. Added new modes:
1256 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1257 specs and code. Protocol TODO #19. Affected files are
1258 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1259 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1261 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1263 * Added STATS command to the protocol after all, to return
1264 various statistical information about the network. It can
1265 be used by clients to retrieve statistical information, and
1266 servers may use it to to fetch cell and network wide
1267 statistics from router. Updated the protocol specs and
1268 implemented it to the server. Protocol TODO #16.
1269 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1270 silcd/command_reply.[ch].
1272 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * The LIST command reply in client libary now adds new channel
1275 entry if the returned channel doesn't exist yet in cache,
1276 and returns the channel entry to the application in the
1277 command_reply client operation. Affected file is
1278 lib/silcclient/command_reply.c.
1280 * Changed the channel message payload's MAC generation to
1281 include the IV in the MAC as well. This way all relevant
1282 parts of the channel message payload are authenticated also
1283 with the channel message MAC (and not only by packet MAC).
1284 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1285 Affected file is lib/silccore/silcchannel.c.
1287 * Fixed the SKE to save the remote version, since the
1288 silc_ske_parse_version mistakenly checked wrong version,
1289 after it replaced the start payload. Affected files are
1290 lib/silcske/silcske.[ch].
1292 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1294 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1295 string utility functions. Added there also new functions
1296 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1297 Affected files lib/silcutil/silcstrutil.[ch].
1299 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1300 files are lib/silcutil/silcstrutil.[ch].
1302 * Defined that the security property fields in SKE SHOULD be
1303 UTF-8 encoded, defined that version string MUST be US-ASCII
1304 encoded, defined that passphrases sent in connection
1305 authentication protocol MUST be UTF-8 encoded. Implemented
1306 these to the client and server. Defined also that other
1307 passphrases sent in the protocol MUST be UTF-8 encoded.
1308 Affected files are lib/silcske/silcske.c,
1309 lib/silcclient/protocol.c, silcd/protocol.c,
1310 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1312 * Changed the silc_client_close_connection interface to not
1313 need the SilcSocketConnection which should not be visible
1314 to application. Affected files are lib/silcclient/client.c
1315 and lib/silcclient/silcclient.h.
1317 * Rewrote the text for Private Message Key Payload in the
1318 protocol specification. Protocol TODO #11.
1320 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1322 * Upgraded the protocol version to 1.1, updated protocol specs
1325 * Added the nickname as new argument to NICK_CHANGE notify and
1326 added it to protocol specs and implemented it to client and
1327 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1328 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1329 lib/silcclient/client_notify.c.
1331 * Added the killer's client ID to the KILLED notify and added
1332 it to protocol specs and implemented it to client and server.
1333 Protocol TODO #13. Affected files are silcd/command.c,
1334 silcd/packet_receive.c, packet_send.[ch],
1335 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1336 The killer's client entry is now returned to application in
1337 the `notify' client operation.
1339 * Fixed the Max Argument fields that had too large value set
1340 in the protocol specs. Protocol TODO #14.
1342 * Added the LEAVE command reply to return the ID of parted
1343 channel. Updated protocol specs and implemented it to the
1344 client and server. Protocol TODO #15. Affected files are
1345 silcd/command.c, lib/silcclient/command_reply.c. The channel
1346 entry is now returned to application in the `command_reply'
1349 * Rewrote the version SKE version checking in client libary
1350 and in server to use the silc_parse_version_string. Affected
1351 files are lib/silcclient/protocol.c, silcd/protocol.c.
1353 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1354 commands that was missing it, and updated protocol specs and
1355 the server implementation. Protocol TODO #10. The affected
1356 file is silcd/command.c.
1358 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1359 generic reply to a generic request (REQUEST flag), and
1360 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1361 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1362 to define the payload for DATA flag. Added the flags to
1363 the implementation. Protocol TODO #9. Affected file is
1364 lib/silccore/silcchannel.h.
1366 Changed the client library to return the message length
1367 to application as well in the channel_message and private_message
1368 client operations. Affected files are
1369 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1370 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1371 and lib/silcclient/client_ops_example.c.
1373 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1374 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1375 the channel. Updated protocol specs and impelemented this
1376 to client and server. Protocol TODO #6. Affected files are
1377 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1378 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1380 Added new options m and M to CMODE command in Irssi SILC
1381 client to set these modes.
1383 * Deprecated all administrative commands from SILC protocol
1384 since they are highly implementation specific commands.
1385 Updated protocol specs. Moved the old commands in
1386 implementations to private range of command types. Affected
1387 files are silcd/command.c, lib/silcclient/command.c and
1388 lib/silcclient/command_reply.c. Protocol TODO #8.
1390 * Fixed a bug in server where sending unknown command crashes
1391 the server. Affected file silcd/command.c.
1393 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1395 * Added SILC_PROTOCOLVERSION macro to check protocol version
1396 of a socket connection. The affected file is
1397 lib/silcutil/silcsockconn.h.
1399 * Added better error logging in rekey protocol. Affected file
1402 * Do not check public key types in SKE during rekey. Affected
1403 file lib/silcske/payload.c.
1405 * Fixed the rekey protocol with PFS, which was totally broken.
1406 Affected file silcd/protocol.c.
1408 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1410 * Some client implementations quit network by doing first LEAVE
1411 and then immediately SIGNOFF (like Bombyx). We now do check
1412 after a short time after LEAVE notify and check whether the
1413 client is still valid after LEAVE, and if not we remove it from
1414 cache. Affected file is lib/silcclient/client_notify.c.
1416 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1418 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1419 it's good not to have security holes here.
1421 * Fixed a negative refcount situtuation for the config context.
1422 Affected file is silcd/serverconfig.c.
1424 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1426 * ROBOdoc documented lib/silcutil/silcutil.h.
1428 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1430 * Optimized even more the SilcPacketContext structure. Now
1431 totally saved 16 bytes of memory per context after optimization.
1432 Affected files are lib/silccore/silcpacket.[ch].
1434 * Made strict checks for valid SILC IDs. Affected file is
1435 lib/silccore/silcid.c.
1437 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1439 * Changed the object argument for silc_cipher_register,
1440 silc_hash_register, silc_hmac_register and silc_pkcs_register
1441 to const. Affected files are lib/silccrypt/silccipher.[ch],
1442 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1444 * Changed the silc_get_username and silc_get_real_name to
1445 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1447 * Fixed the Irssi SILC Client to use the silc_get_username and
1448 silc_get_real_name insted of glib routines since the glib
1449 routines only corrupt stack. Fixes the Irssi SILC to work in
1450 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1452 * Fixed the Irssi to not use g_get_home_dir since it crashes
1453 or returns garbage on cygwin and corrupts stack. Added function
1454 get_home_dir to Irssi routines. Affected files are
1455 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1457 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1459 * Made some structure optimizations. SFTP memory FS MemFSEntry
1460 entry structure. Optimized SilcTask structure. Optimized
1461 SilcPacketContext structure.
1463 Affected files lib/silcsftp/sftp_fs_memory.c,
1464 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1466 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1468 * And yet again reverted back the config thing since Johnny
1469 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1472 * Fixed memory leaks from config object. Affected files are
1473 silcd/serverconfig.[ch].
1475 * Added support for adding new connections to the server in rehash.
1476 After rehash they take effect.
1478 Added support for changing the maximum allowed connections in
1479 rehash. The number can grow but going smaller is not supported.
1481 Added function silc_server_num_sockets_by_remote to the
1482 silcd/server_util.[ch].
1484 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1486 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1488 * Added preliminary checking during config parsing for a valid
1489 public/private key and removed further checks in the code.
1490 Affected files are silcd/serverconfig.[ch], server.c.
1492 * Moved functions silc_server_drop() and silc_server_daemonise()
1493 from server.c to silcd.c since they are stricly related to
1494 the application activity.
1496 * Reverted a small part of the automatic ref/unref since
1497 it caused a double unref in some situations. Affected
1498 files are silcd/silcd.[ch], server.c, serverconfig.c.
1500 * Added some .cvsignore files in the lib directory.
1502 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * Fixed silc_net_gethostbyaddr to correctly resolve by
1505 address. Affected file lib/silcutil/silcnet.c.
1507 * Fixed the notify relaying to client. The HMAC to be used
1508 with relayed packets ws wrong and caused decryption failure
1509 at the client end. Affected file is silcd/packet_receive.c.
1511 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1513 * Created new branch silc_protocol_1_0_branch.
1515 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1517 * Changed the silc_server_config_* routines to be SilcServer
1518 independent. They are now officially application specific code
1519 and not part of generic server implementation. Affected files
1520 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1522 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1524 * Added automatic referencing of config context in the
1525 silc_server_config_alloc, and automatic unreferencing in the
1526 silc_server_config_destroy. Affected files are
1527 silcd/serverconfig.[ch], silcd/silcd.c.
1529 * Fixed the silc_log_quick handling in the logging routines.
1530 It didn't log quickly when it was TRUE. Affected file is
1531 lib/silcutil/silclog.c. Also the flush delay was set even
1532 if it was 0 in config file. Affected file is
1533 silcd/serverconfig.c.
1535 * Added support for changing key pair of the server in rehash.
1536 Affected file silcd/server.c.
1538 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1540 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1541 too early, before getting the channel entry. Affected file
1542 is silcd/packet_receive.c.
1544 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1546 * Added functions silc_server_config_[ref/unref], these are used
1547 to prevent that the config object is destroyed.
1549 No longer directly affect global variables silc_log_quick and
1550 silc_log_delay, they are first cached inside the config object
1551 and then applied with silc_server_config_setlogfiles().
1553 silc_server_config_set_defaults() is now internal to
1554 serverconfig.c, there are no reasons to show this internal stuff
1557 Affected files are silcd/serverconfig.[ch].
1559 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1560 fprintf's to stderr, since some code may be executed again after
1561 the server went into the background. Affected files are
1564 * Added rehash support. Added function silc_server_rehash() that
1565 will perform all the basic tasks of the rehashing procedure.
1567 * Added command line option `-x, --hexdump'. This will enable the
1568 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1569 The option `--hexdump' implies `--debug'.
1571 * Fixed a bad bug in the logging APIs (silcutil library) where
1572 the application would crash after calling silc_log_reset_all().
1574 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1576 * Fixed the KICKED notify handling in client library to
1577 correctly remove the channel and all entries from the
1578 channel when I was kicked. This bug crashed the client.
1580 Fixed yet another but in KICKED notify handling to remove
1581 the kicked client correctly from the channel.
1583 Affected file is lib/silcclient/client_notify.c.
1585 * Fixed a minor bug in looking up correct client entry
1586 in KICKED notify in server. Affected file is
1587 silcd/packet_receive.c.
1589 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1590 sources correctly to distribution. Fixes --with-gmp option.
1592 * Removed the manual rehashing from ID Cache, and changed it
1593 to use the SILC Hash Table's auto rehash feature. Affected
1594 file is lib/silccore/silcidcache.c.
1596 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1598 * Fixed a bug in the silc_client_nickname_format function that
1599 handles the multiple same nickname formatting. Two clients
1600 with same nickname caused problems after the first one left
1601 and rejoined. It didn't format the nickname correctly.
1602 Affected file is lib/silcclient/idlist.c.
1604 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1606 * Don't change the topic if olod topic is same as new one.
1607 Affected file is silcd/packet_receive.c.
1609 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Added cross-reference support to the SILC Documentation
1612 generator. All types across all HTML files are now cross-
1613 referenced. Affected files util/robodoc/generator.c and
1614 scripts/silcdoc/silcdoc.
1616 * Added file lib/silcutil/silctypes.h to include all the
1617 arithmetic type definitions and some macros. Removed
1618 includes/bitmove.h and moved macros to silctypes.h.
1620 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1624 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Added `type' argument to silc_id_payload_parse_id function which
1627 now returns the type of the ID to the sent pointer. Affected
1628 file is lib/silccore/silcid.[ch].
1630 * Added check for CMODE_CHANGE notify type that mode change is
1631 allowed by the sender. Affected file silcd/packet_receive.c.
1633 * Added check for CUMODE_CHANGE notify type that mode change is
1634 allowed by the sender. Affected file silcd/packet_receive.c.
1635 Added the ID type as CUMODE_CHANGE notify type as argument
1636 to the `notify' client operation. Affected files are
1637 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1639 * Added function silc_client_add_server to the client library.
1640 Added support for resolving also channel and server info when
1641 received unknown entity in notify packet. Affected files are
1642 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1644 * Added function silc_command_get_status to return the command
1645 status from the command reply's argument payload. Affected files
1646 are lib/silccore/silccommand.[ch].
1648 * Added check for KICKED notify type that the kicking is
1649 allowed by the client. Affected file silcd/packet_receive.c.
1651 * Created function silc_get_input which can be used to get input
1652 (echo on or off) from user on command line. Affected files are
1653 lib/silcutil/silcutil.[ch].
1655 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1657 * Optimized silc_server_packet_relay_to_channel function.
1658 Added new function silc_channel_message_payload_encrypt which
1659 can be called directly if channel message payload needs to
1660 be encrypted and is already encoded (no need to call _encode
1661 function). Packet relaying is now done by router without any
1662 extra memory allocations. Affected files are
1663 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1664 silcd/packet_send.c.
1666 * Fixed the INVITE notify handling. It took wrong arguments
1667 as invite list and invite delete. Affected file is
1668 silcd/packet_receive.c.
1670 * Added check for TOPIC_SET notify type that the topic change is
1671 allowed by the client. Affected file silcd/packet_receive.c.
1673 * Added check for INVITE notify type that inviting is allowed by
1674 the client. Affected file silcd/packet_receive.c.
1676 * Changed the silc_server_client_on_channel to return the
1677 SilcChannelClientEntry as well. Moved the function
1678 silc_server_check_cmode_rights to server_util.[ch].
1679 Affected files are silcd/server_util.[ch], silcd/command.c.
1681 * Added function silc_server_check_umode_rights to check whether
1682 changing client's user mode is allowed. Added check for
1683 UMODE_CHANGE notify type that the umode change is allowed
1684 by the client. Affected files are silcd/server_util.[ch],
1685 silcd/packet_receive.c and silcd/command.c.
1687 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1689 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1690 ID length. It ignored that ID can be IPv6 based as well.
1691 Affected file lib/silccore/silcpacket.h.
1693 * Fixed the silc_id_id2str and silc_id_str2id to take the
1694 IPv6 address offset's into consideration. Affecte file is
1695 lib/silccore/silcid.c.
1697 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1699 * Fixed the internal Unix scheduler functions to check for
1700 NULL context they may receive. The affected file is
1701 lib/silcutil/unix/silcunixschedule.c.
1703 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1705 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1706 can specify different directory with --home command line
1707 parameter. Affected files irssi/src/silc/core/client_ops.c,
1710 * SILC-specific commands aren't now executed if the active server
1711 isn't of SILC-type, so there won't be problems with having
1712 IRC and SILC protocol support in same client. Affected files
1713 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1716 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1718 * Improved the signal support in SILC Schedule. Added new
1719 function silc_schedule_signal_call which is used by application
1720 to mark a signal to be called. It is now safe to perform
1721 any kind of tasks in signal callbacks since it is guaranteed
1722 that the application specified signal callback is called
1723 after the signal is over. Affected files are
1724 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1726 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1728 * Added `name' field to SilcChannelPrivateKey to represent
1729 application given name for the key. Moved also the context from
1730 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1731 Added the `name' argument also to the function
1732 silc_client_add_channel_private_key.
1734 Added function silc_client_current_channel_private_key to set the
1735 current channel private key in use.
1737 Added "change" command to KEY command which can be used to change
1738 the current channel private key. Bound the command also to
1739 alt+K (Alt+Shift+k).
1741 Also affected files lib/silcclient/client_channel.c,
1742 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1744 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1746 * Added silc_rng_get_byte_fast function in to the
1747 lib/silccrypt/silcrng.[ch].
1749 * Changed the interface of silc_packet_assemble and the
1750 silc_packet_send_prepare. If silc_packet_assmble is now
1751 called the application does not call silc_packet_send_prepare
1752 because the library will call it automatically. These
1753 interfaces now also return a reference to the outgoing buffer
1754 which includes the assembled packet, which the application can
1755 use to encrypt the packet.
1757 Affected files are lib/silccore/silcpacket.[ch],
1758 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1759 silcd/packet_send.c, server_backup.c and packet_receive.c.
1761 * Fixed a packet sending bug on very high load, where outgoing
1762 packet queue wasn't handled correctly and packets got corrupted.
1763 Affected files are lib/silcutil/*/silc*sockconn.c,
1764 lib/silcclient/client.c and silcd/server.c.
1766 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1768 * Added macro SILC_PACKET_DATALEN which can be used during
1769 packet assembling to check whether the data to be added to
1770 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1771 len is truncated until it fits it.
1773 Added checks for maximum length of channel message payload and
1774 private message payload also.
1776 Added checks for maximum packet length in server and in
1779 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1780 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1781 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1782 lib/silcclient/client_prvmsg.c.
1784 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1786 * Added silc_server_packet_queue_purge call to the
1787 silc_server_disconnect_remote to assure that all data in the
1788 queue before disconnecting is sent to the network. Affected
1789 file silcd/server.c.
1791 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1793 * Added the deleting of server's own ID cache entry to the
1794 silc_server_free function. Free also everything else that
1795 has been allocated in silc_server_init. The affected file
1798 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1800 * Added functions silc_parse_version_string, silc_version_to_num,
1801 and silc_ske_parse_version to parse SILC protocol style version
1802 strings. Affected files lib/silcutil/silcutil.[ch] and
1803 lib/silcske/silcske.[ch].
1805 * Added new configuration params: version_protocol, version_software
1806 and version_software_vendor to specify what version the remote
1807 host must at least be to be able to connect to server. The vendor
1808 string can be regex matched too. Added new function
1809 silc_server_connection_allowed to check maximum number of allowed
1810 connections, and allowed versions for incoming connections.
1811 Affected files are silcd/server.c, server_util.[ch] and
1814 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1816 * Added preliminary support for signals in scheduler. The
1817 signals we care about are now blocked always when the scheduler
1818 is locked. This way we can synchronise the use of signal with
1819 scheduler. It is guaranteed that when signal occurs the scheduler
1820 is not locked, and thus new tasks can be safely added to the
1823 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1824 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1825 Added new platform specific routines
1826 silc_schedule_internal_signals_[un]block and
1827 silc_schedule_internal_signal_[un]register.
1829 Added new functions to SILC Schedule API:
1830 silc_schedule_signal_[un]register. Each signal that application
1831 is going to use should be registered to the scheduler.
1833 Affected files are lib/silcutil/silcschedule.[ch],
1834 lib/silcutil/*/silc*schedule.c.
1836 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1838 * Check for unauthenticated client and server in the
1839 silc_server_new_client and silc_server_new_server functions.
1840 Affected file silcd/packet_receive.c.
1842 * Added function silc_string_is_ascii to check whether given
1843 string is 7-bit ASCII string. Affected files are
1844 lib/silcutil/silcutil.[ch].
1846 * Added function silc_id_is_valid_server_id into the
1847 silcd/serverid.c and added checking for valid Server ID's in
1848 silc_server_new_server. The Server ID must always be based
1849 on the server's public IP address.
1851 * Added logging of DISCONNECT packet message in the server.
1852 Affected file silcd/server.c.
1854 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1856 * Changed all library interfaces that use Global RNG to also
1857 accept SilcRng as argument. Affected files are
1858 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1859 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1860 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1861 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1862 lib/silccrypt/rsa.c.
1864 * Added function silc_pkcs_generate_key to the
1865 lib/silccrypt/silcpkcs.[ch] for applications so that they
1866 don't need to do pkcs->pkcs->init calls anymore.
1868 * Remove SilcSocketConnection from the SFTP API since it really
1869 wasn't needed there. The application has the information
1870 saved in its contexts anyway and the SFTP layer doesn't need
1871 know about it. Affected files lib/silcsft/silcsftp.h and
1872 lib/silcsftp/sftp_[server/client].c.
1874 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1875 The SilcSimContext is not SilcSim.
1877 * Fixed possible buffer overflows in silc_id_render in the
1878 lib/silcutil/silcutil.c.
1880 * On EPOC the global crypto module lists are not used at all
1881 in the crypto library. Added support for using the constant
1882 algorithm list on EPOC. Affected files are
1883 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1886 * Fixed the handling of third parameter of KICKED notify, since
1887 it was mistakenly updated to SILC Protocol 1.0 even though it
1888 is to be included in 1.1. Since it is not in 1.0 it is not
1889 mandatory, and this fix now handles it only if it is provided,
1890 and it is not error if it is not provided. Affected file
1891 lib/silcclient/client_notify.c.
1893 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1895 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1896 client. Affected file irssi/src/silc/core/client_ops.c.
1898 * Merged with Irssi 0.8.4 from irssi.org CVS.
1900 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1902 * Check for valid socket connection in client entries before
1903 sending any messages. Fixes a crash, but doesn't fix some
1904 other underlaying bug that is lurking there. Affected
1905 file silcd/packet_send.c.
1907 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1909 * $usermode, $cumode and $cumode_space expandos shouldn't do
1910 anything with non-SILC server records. Affected file
1911 irssi/src/silc/core/silc-expandos.c
1913 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1915 * Fixed the silc_net_check_[host/local]_by_sock to support
1916 IPv6 bound sockets as well. Now they can return IPv6 addresses
1917 as well. Affected file lib/silcutil/silcnet.c.
1919 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1920 Affected lib/silcutil/unix/silcunixnet.c.
1922 * Fixed ID rendering (at least on some platforms, not NetBSD)
1923 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1925 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1927 * Added silc_hash_public_key and silc_hash_public_key_compare
1928 functions to be used with SilcHashTable. They can be used to
1929 hash public keys and compare public keys in hash table. Affected
1930 file lib/silcutil/silcutil.[ch].
1932 * Added support for specifying multiple public keys for Client
1933 connection section in server configuration file. This makes it
1934 possible to accept multiple public keys from same host, or to
1935 make a section that accepts any incoming host, and have the
1936 accepted public keys listed in the section.
1938 Added functions silc_sever_[find/get]_public_key, added the
1939 support for this actually to all connection sections but only
1940 the Client section is currently allowed to specify multiple
1943 Affected files are silcd/server.c, server_internal.h,
1944 command.c, protocol.c, server_util.[ch], packet_receive.c.
1946 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1948 * Merged Irssi 0.8.2 from irssi.org CVS.
1950 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1952 * If silc_debug is TRUE, also output standard logging messages
1953 to stderr with the debug output.
1955 Made silc_log_reset_all() flushing all channels before returning.
1956 Also fixed some documentation typos.
1958 Affected files are lib/silcutil/silclog.[ch].
1960 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1962 * Fixed the server to check correctly the amount of connections
1963 from single host, by checking also the type of the connection.
1964 Fixed also the comparison of number of connections and number
1965 of allowed connections. Affected files are silcd/server.c,
1968 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1970 * Fixed the USERS command reply to save the user's mode on the
1971 channel as well. Fixed JOIN command reply to check whether a
1972 client is on channel already and not join it twice. Affected
1973 file lib/silcclient/command_reply.c.
1975 * Added new file silc-expandos.c into irssi/silc/core/ to return
1976 various stuff for various signal for the statusbar etc. updating.
1977 Now Irssi SILC client prints channel user modes etc. on the
1980 * The user mode (like server/router operator changes) is now shown
1981 on the Irssi SILC client's statusbar. The affected files are
1982 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1984 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1986 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1987 to SILC_SCHEDULE_[UN]LOCK macros.
1989 * Added more error printing to logs in server code. Affected
1990 files silcd/server.c and silcd/protocol.c.
1992 * Fixed -S option parsing in Irssi SILC Client. Affected file
1993 irssi/src/silc/core/silc-core.c.
1995 * Added silc_buffer_alloc_size function. Affected file is
1996 lib/silcutil/silcbuffer.h.
1998 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2000 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
2001 constants. Affected files in
2002 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
2005 * Changed the internal SFTP Memory FS table to const. Affected
2006 file lib/silcsftp/sftp_fs_memory.c.
2008 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2010 * Fixed the buffer formatting and unformatting routines to
2011 check the size of 64 bits types with sizeof(). Affected
2012 file is lib/silcutil/silcbuffmt.c.
2014 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2016 * Removed 0.6.x backwards support.
2018 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2020 * Changed all integer type names:
2021 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
2022 to avoid collisions with other libraries using same type names
2025 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2027 * Added `prefer_ipv6' argument to the functions
2028 silc_net_gethostbyname[_async]. If it is TRUE it will return
2029 IPv6 address over IPv4. If FALSE IPv4 address is returned
2030 even if IPv6 address was found. Affected files
2031 lib/silcutil/silcnet.[ch].
2033 * Added support silc_net_create_connection[_async] to fallback
2034 to IPv4 address if IPv6 address could not be used (like if
2035 it doesn't work on a specific system). Affected file in
2036 lib/silcutil/unix/silcunixnet.c.
2038 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2040 * Added silc_schedule_reinit function to do the enlarging
2041 of the max tasks handling capabilities of the scheduler.
2042 Affected files lib/silcutil/silcschedule.[ch].
2044 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2046 * Added automatic extern "C" { ... } for C++ compilers so the
2047 application does not need to define them. Affected file
2048 includes/silcincludes.h.
2050 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2051 old name went against naming convention. Applications now
2052 include "silcclient.h" instead of "clientlibincludes.h".
2053 Removed includes/clientlibincludes.h, it is redundant now.
2055 * Renamed includes/version.h to silcversion.h.
2057 * Added really preliminary support for OS/2 into the util
2058 library. Only thread & mutex API is implemented, others
2059 are still to be implemented. Created the lib/silcutil/os2/
2060 directory. Created also file includes/silcos2.h.
2062 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2064 * Added preliminary BeOS support into the util library.
2065 Created lib/silcutil/beos/, and implemented all the needed
2066 functions to support SILC on BeOS. Created also file
2067 includes/silcbeos.h.
2069 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
2071 * Added proper initializations to silc's irssi code, so it's
2072 now possible to load it as module. Affected files
2073 irssi/src/silc/core/silc-core.c,

2091 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2093 * Added `user_count' to the SilcChannelEntry which now tells the
2094 number of users on the channel. The user count is now saved
2095 in normal server of global channels as well. Affected files
2096 silcd/server.c, idlist.h, packet_receive.c and command.c.
2098 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2099 include file utility functions.
2101 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2102 instead of calling directly OS routines.

2115 the SKE interface a bit.
2117 * Fixed padding problem in PKCS#1. The padding was not actually
2118 random since the random number generator was used incorrectly.
2119 This security bug affects only when encrypting with PKCS#1, and
2120 it is not currently used at all in SILC. SILC only use signing
2121 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2184 Affected files irssi/src/silc/core/silc-core.c,
2185 irssi/src/fe-text/silc.c.
2187 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2189 * Added new configuration options and blocks:
2190 keepalive_secs, reconnect_count, reconnect_interval,
2191 reconnect_interval_max, reconnect_keep_trying and
2192 require_reverser_lookup. Added ConnectionParam block, and
2193 implemented the connection parameters when connecting as
2194 initiator and when accepting connections as responder.

2206 the connection configuration object from the SilcServerConnection
2207 object instead of finding it during the connecting phase.
2208 Added the configuration object to SilcServerConnection struct.
2209 Affected files silcd/server_internal.h, server.c.
2211 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2213 * Add the client on channel after it was resolved at the
2214 channel message receiving, and it was not already on the
2215 channel. Affected file lib/silcclient/client_channel.c.
2217 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2233 authentication to be set at the same time.
2235 Added `prefer_passphrase_auth' setting in config file which
2236 can be used to set to prefer passwd auth if both passwd and
2237 public key is set. If not set, public key is preferred.
2238 This has effect only when being initiator (responder will try
2241 Added support for authentication with passphrase and public key
2242 at the same time. The passphrase is tried first always since
2243 it is faster to check.
2245 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2247 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2249 * Merged the new SILC Config library, with the server parsing

2293 * Fixed the file transfer's key agreement payload to include
2294 zero port also if the hostname is NULL because it could not
2297 Call file transfer monitor callback now also if error occurs
2298 during key agreement protocol.
2300 Changed the silc_client_file_send interface to return the
2301 SilcClientFileError instead of session id. The session ID
2302 is returned into pointer provided as argument.
2304 Check that the file exists locally before sending the
2305 file transfer request at all.
2307 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2309 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

2319 file lib/silcutil/silclog.c.
2321 * Fixed the channel message payload decryption in the function
2322 silc_channel_message_payload_decrypt to not modify the original
2323 buffer before it is verified that the message decrypted
2324 correctly. Otherwise, next time it is called with correct
2325 channel key it won't encrypt since the payload is corrupted.
2326 Affected file lib/silccore/silcchannel.c.
2328 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2340 * Fixed a bug in hash table internal routine for traversing
2341 the table with foreach callback. The current entry may
2342 become invalid in the callback but it was referenced after
2343 the callback returned.
2345 Do not allow auto rehashing of hash table during the
2346 silc_hash_table_foreach operation, for same reasons as it is
2347 not allowed for SilcHashTableList. Affected files are
2348 lib/silcutil/silchashtable.[ch].
2350 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2356 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2358 * Fixed private message handling. It used some old code that
2359 caused the client to crash. Affecte file is
2360 lib/silcclient/client_prvmsg.c.
2362 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2364 * Added function silc_client_add_channel,
2365 silc_client_replace_channel_id, and removed functions
2366 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2367 from client library.
2369 * Added cross reference of the joined channels to the
2370 SilcClientEntry, and changed the SilcChannelEntry's
2371 users list to SilcHashTable. The affected files are
2372 lib/silcclient/idlist.[ch].
2374 * Fixed a bug in hash table tarversing. While the hash table
2375 is traversed with SilcHashTableList the table must not be
2376 rehashed. It is now guaranteed that auto rehashable tables
2377 are not rehashed while tarversing the list. Also defined that
2378 silc_hash_table_rehash must not be called while tarversing
2379 the table. Added function silc_hash_table_list_reset that must
2380 be called after the tarversing is over. The affected files are
2381 lib/silcutil/silchashtable.[ch].
2383 * Changed all hash table traversing to call the new
2384 silc_hash_table_list_reset in server and in client library.
2386 * Added function silc_client_on_channel to return the
2387 SilcChannelUser entry if the specified client entry is joined
2388 on the specified channel. This is exported to application as
2389 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2391 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2393 * Fixed founder regaining problem with JOIN command on normal
2394 server. The notify for mode change must be sent always and
2395 not only if !cmd->pending. Affected file silcd/command.c.
2397 * Fixed the WHOWAS command's reply sending to support the
2398 lists correctly. Affected file silcd/command.c.
2400 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2402 * When sending JOIN command to router for processing the
2403 sender's old command identifier was not saved back to the
2404 sender's command context, fixed now. The affected file is
2407 * Create the key in JOIN command of the router did not return
2408 the channel key, added check for this. Affected file is
2411 * Fixed a channel ID update bug in JOIN command reply. Do
2412 not directly upgrade the ID but call the function
2413 silc_idlist_replace_channel_id if the ID was changed.
2414 Affected file silcd/command_reply.c.
2416 * Fixed memory leaks from command calling if it would fail.
2417 Affected file silcd/command.c.

2429 * Removed TRQ from lib/trq, not needed anymore.
2431 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2432 with server connections. Later this will be configurable
2433 in config file after new config file is done. Affected file
2436 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2438 * Fixed a crash in server related to channel announcements.
2439 Affected file silcd/server.c.
2441 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2443 * Fixed memory leaks in silc_server_create_new_channel*
2444 functions. Affected file silcd/server.c.
2446 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2447 which ID was changed. This way the router will send the
2448 user list for the channel again, and server won't be in
2449 desync in some rare circumstances. Affected file is
2450 silcd/packet_receive.c.
2452 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2467 file for application programmers to quickly start using
2468 the SilcClientOperation functions in their application.
2469 Updated the lib/silcclient/README as well to tell about this
2470 nice file made available.
2472 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2474 * Call silc_server_remove_from_channels when removing client
2475 entry when NO_SUCH_CLIENT_ID was received. Affected file
2476 is silcd/command_reply.c.

2480 * Added server & router operator statistics updating. Affected
2481 file silcd/packet_receive.c and silcd/command.c.
2483 * Fixed the SERVER_SIGNOFF notify handling on normal server
2484 not to save the history information for clients. Same was
2485 fixed earlier in remove_clients_by_server function, but not
2486 here. Affected file silcd/packet_receive.c.
2488 * Raised the default connection-retry count from 4 to 7 in
2489 server. Affected file silcd/server.h.
2491 * Cancel any possible reconnect timeouts when we start the
2492 key exchange. Affected file silcd/server.c.
2494 * Do not reconnect on connection failure when SCONNECT was
2495 given. Affected files silcd/server.[ch].
2497 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2499 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2501 * Fixed the NICK command to always give the unformatted
2502 nickname to the one giving the NICK command. If unformatted
2503 nickname is cached already it will be formatted and the
2504 local entry will always get the unformatted nickname.
2505 Affected file lib/silcclient/idlist.c.
2507 * Fixed some double frees from client library commands.
2508 Affected file is lib/silcclient/command.c.
2510 * Fixed CUMODE command in server to assure that no one can
2511 change founder's mode than the founder itself, there was a
2512 little bug. Affected file silcd/command.c.
2514 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2516 * Removed the SilcClientCommandDestructor from the client
2517 libary, it is not needed anymore. Affected files are
2518 lib/silcclient/silcapi.h, command[_reply].[ch],
2519 client_notify, idlist.c.
2521 * Fixed GETKEY command to first resolve client, and then
2522 resolve the server only if the client was not found, instead
2523 of resolving both at the same time. Affected file is
2524 lib/silcclient/command.c.
2526 * Added silc_client_start_key_exchange_cb and lookup the
2527 remote hostname and IP address before starting the key
2528 exchange with server. The affected file is
2529 lib/silcclient/client.c.
2531 * The server's public key is now saved using the IP address
2532 of the server and not the servername for the filename.
2533 The hostname public key filename is checked as an fall back
2534 method if the IP address based filename is not found.
2536 Fixed the GETKEY command to save the fetched server key
2537 in correct filename.
2539 Print the remote server's hostname now when new key is
2540 received during connection process. Affected file is
2541 irssi/src/silc/core/client_ops.c.
2543 * Return always our own public key to the client if it asks
2544 for it with GETKEY command. Affected file silcd/command.c.
2546 * Removed the use_auto_addr variable from default config
2547 file since it was in wrong section. Affected file is
2550 * Fixed TOPIC_CHANGE notification to not route it when it
2551 was sent using silc_server_send_notify_to_channel function.
2552 Affected file silcd/command.c.
2554 * Fixed silc_server_send_notify_kicked to send the kicker's
2555 Client ID also, it was missing. Affected files are
2556 silcd/command.c, silcd/packet_send.[ch].
2558 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2560 * Do not save client history information in SERVER_SIGNOFF.
2561 Fixes the bug in normal server that it does not detect
2562 the client becoming valid after the server becomes back
2563 online. Affected file silcd/server_util.c.
2565 * Added `sock_error' field into the SilcSocketConnection
2566 context. When error occurs during socket operation (read
2567 or write) the error is saved. Added also new function
2568 silc_socket_get_error to return human readable socket error
2569 message. Affected files are lib/silcutil/silcsockconn.[ch],
2570 lib/silcutil/unix/silcunixsockconn.c, and
2571 lib/silcutil/win32/silcwin32sockconn.c.
2573 * The server now prints the socket error message in the
2574 signoff for client. Affected file silcd/server.c.
2576 * Fixed the `created' channel information sending from router
2577 to server in JOIN command. Checks now whether the channel
2578 really was created or not and set it according that.
2580 Fixed the JOIN command to use the client entry's current
2581 ID during the joining procedure instead of the one it sent
2582 in the command (it is checked though), since it can change
2583 between the packet processing and command processing, and
2584 would just case unnecessary pain in the client end. Affected
2585 file silcd/command.c.
2587 * Fixed a channel key payload sending to use correct channel
2588 ID when the server was forced to change the channel's ID by
2589 router. Router sent the key payload with the old Channel ID.
2590 Affected file silcd/packet_receive.c.
2592 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2594 * Call silc_server_save_channel_key only if the key payload
2595 was provided in the JOIN command's command reply. Affected
2596 file silcd/command_reply.c.
2598 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2600 * Fixed silc_mp_sizeinbase to return the value correctly with
2601 MPI. Affected file lib/silcmath/mp_mpi.c.
2603 * Fixed the stop_server signal to correctly stop the scheduler
2604 and gracefully stop the server when SIGTERM or SIGINT signals
2605 are received. Affected file silcd/silcd.c.
2607 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2609 * Simple handling of TERM and HUP signals. Also added some log
2610 flushing call around. Affected file is
2613 * Fixed small bugs in silclog.c. Now buffering output will take
2614 effect after 10 seconds since startup: This will ensure that
2615 no important startup messages are lost. Also output redirection
2616 will preserve original format ([Date] [Type] message).
2617 Affected file is lib/silcutil/silclog.c.
2619 * Added two options to the config file, in the logging section:
2620 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2621 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2623 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2625 * Do not print the warning about log files not being initialized
2626 more than once to avoid excess logging. Affected file is
2627 lib/silcutil/silclog.c.
2629 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2630 the SIM copying in make install in Makefile.am.pre.
2632 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2634 * Rewritten silclog APIs. Globally interesting changes follows:
2635 silc_log_set_files() changed to silc_log_set_file().
2636 silc_log_set_callbacks() changed to silc_log_set_callback().
2637 ROBOdoc documented silclog header file.
2638 SilcLogCb now returns bool to wether inihibit the default
2639 handler or not (to keep the old behaviour return always TRUE).
2640 The new APIs should also fix the problem of the
2641 silcd_error.log file that was written in the current directory.
2644 Log files streams will remain opened after silc_log_set_file()
2645 call, means less CPU usage notably on high traffic servers.
2646 File streams are now full buffered, and flushed to the disk
2647 every 5 minutes, lesses HD activity and CPU usage.
2648 Messages can be redirected, allowing admins to configure
2649 one single logfile for all server messages.
2650 the silc_log_quick global variable to activate fast-logging.
2651 Affected files lib/silcutil/silclog.[ch]
2653 * Changed some code to conform new silclog APIs. Affected
2654 files are doc/example_silcd.conf.in, silcd/server.c
2655 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2658 * Fixed a memory leak that could occur in some situations.
2659 Affected file silcd/serverconfig.c.
2661 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2663 * Added the silc_client_del_client to remove the client from
2664 all channels as well. Affected file lib/silcclient/idlist.c.
2666 * Fixed the client library to correctly remove the client
2667 from all channels when the client entry is being destroyed.
2668 Affected file lib/silcclient/client_notify.c, command.c.
2670 * Added auto-nicking support to the client library. If the
2671 applicatio now sets client->nickname it will be sent to the
2672 server after connecting by the library. This way for example
2673 SILCNICK (or IRCNICK) environment variables will have effect
2674 and always change the nickname automatically to whatever
2675 it is wanted. Affected file lib/silcclient/client.[ch].
2677 * Renamed silc_server_command_bad_chars to the
2678 silc_server_name_bad_chars and moved it to the
2679 silcd/server_util.[ch]. Added also new function
2680 silc_server_name_modify_bad to return nickname that
2681 includes bad characters as new nickname without those
2682 bad characters. This check and modify is now used in
2683 silc_server_new_client when the username is initially set
2684 as nickname, so it must be checked to be valid nickname.
2685 Affected file silcd/packet_receive.c.
2687 * The nickname length is now taken from the packet for real
2688 and not trusted to strlen() since it clearly can return
2689 wrong length for nickname including bad characters. This
2690 also applies to channel names. Affected file silcd/command.c.
2692 * Removed the lib/silcsilm/modules directory. Modules are now
2693 compiled into the lib/silcsim. Fixed the copying of the
2694 modules to follow symbolic links in Makefile.am.pre.
2696 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2698 * Fixed silc_string_regexify list creation. Fixes bugs with
2699 BAN and INVITE commands in server. The affected file is
2700 lib/silcutil/unix/silcunixutil.c.
2702 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Removed the command destructor entirely from the server's
2705 command and command reply routines. It is not needed, and
2706 its usage was buggy and caused crashes. Affected files are
2707 silcd/command[_reply].[ch].
2709 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Cancel protocol and NULL sock->protocol if timeout
2712 occurred during protocol. Affected file silcd/server.c.
2714 * Cancel protocol timeouts always before calling the final
2715 callback, to assure that after final callback is called
2716 no other state will be called for the protocol anymore.
2717 Affected file silcd/protocol.c.
2719 * Print error log if incoming connection configuration could
2720 not be found. Affected file silcd/server.c.
2722 * Fixed JOIN command to correctly save the founder mode
2723 to the client on normal SILC server, when the channel
2724 was created by the router. Affected file silcd/command.c.
2726 * Fixed LIST command (hopefully) to send correct reply
2727 packets. Affected file silcd/command.c.
2729 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * The silc_packet_receive_process now returns FALSE if the
2732 read data was invalid packet, and TRUE if it was ok.
2734 The server now checks that if unauthenticated connection
2735 sends data and its processing fails the server will close
2736 the connection since it could be a malicious flooder.
2738 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2740 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Make sure the warning about error opening a log file is
2743 printed only once and not everytime it fails (produces
2744 too much useless log). Affected file lib/silcutil/silclog.c.
2746 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2748 * Made the silc_server_daemonise() function more readable.
2749 Affected file silcd/server.c.
2751 * Pid file is now optional, the user may comment it out from
2752 the config file. Removed define SILC_SERVER_PID_FILE, we
2753 don't need a default any longer. Affected file
2754 configure.in.pre, lib/Makefile.am.pre.
2756 * Make some use of the pid file. The server now dies at startup
2757 if it detects a valid pid file on his path. The server would
2758 die anyway in this circumstance, because of the bind() failure.
2759 Affected file silcd/silcd.c.
2761 * No longer compiling lib/dotconf.
2763 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Fixed JOIN command parsing not to crash. Affected file
2766 lib/silcclient/command.c.
2768 * Fied the NICK_CHANGE notify to add the new client entry
2769 even it is resolved. This removes an <[unknown]> nick
2770 thingy bug in the client. Affected file is
2771 lib/silcclient/client_notify.c.
2773 * Do not try to allocate 0 bytes (efence does not like it)
2774 in lib/silccore/silccomand.c when encoding payload.
2776 * Do not take IRCNICK as nickname in Irssi SILC client since
2777 it is not possible to set nickname before hand connecting
2778 the server (TODO has an entry about adding auto-nicking
2781 * Changed the silc_server_command_pending to check whether
2782 there already exists an pending entry with the specified
2783 command, command identifier and pending callback. This is
2784 to fix IDENTIFY and WHOIS related crashes that may register
2785 multiple pending commands with same identifier. Affected
2786 file silcd/command.c.
2788 * Fixed the server to reconnect to the router even if it
2789 was already reconnecting and EOF was received. This to
2790 fix a possibility that the server wouldn't ever try to
2791 auto-reconnect to the router. Affected file silcd/server.c.
2793 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Fixed the server's password authentication to use the
2796 length of the locally saved password, and not the one
2797 sent in the packet. Affected file silcd/protocol.c.
2799 * Fixed same password authentication problem in the
2800 Authentication Payload handling routines in
2801 lib/silccore/silcauth.c.
2803 * Yet another password authentication problem fixed with
2804 channel password handling in silcd/command.c.
2806 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2808 * If first character of string in silc_parse_userfqdn is '@'
2809 then do not parse it. Affected file is
2810 lib/silcutil/silcutil.c.
2812 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Fixed minor bug in IDENTIFY command reply sending, which
2815 caused various weird problems during JOIN when it was
2816 resolving names for users. Affected file silcd/command.c.
2818 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed the IDENTIFY command reply sending to chech better valid
2821 clients. It was possible to send incomplete list of replies.
2822 Affected file silcd/command.c.
2824 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Added silc_client_command[s]_[un]register functions now to
2827 dynamically register the commands in client library. Removed
2828 the static table of commands. This allows the client library
2829 to call commands without causing the application to know about
2830 what commands library has called.
2832 Removed the INFO command reply kludge to detect when the command
2833 was called by library. Now library use its own command reply
2834 function for INFO command.
2836 Added function silc_client_command_call to call a command.
2837 Application can use it to call command, not access the structure
2840 Now all commands that are sent by the client library (not
2841 explicitly sent by application) use own command reply functions.
2843 Affected files around lib/silcclient/ and in
2844 irssi/src/silc/core/.
2846 * Fixed the WHOIS command reply sending to chech better valid
2847 clients. It was possible to send incomplete list of replies.
2849 Fixed the WHOIS and IDENTIFY to send the request to router
2850 if normal server did not do it and did not find any results.
2852 Affected file silcd/command.c.
2854 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Moved the internal data from SilcClient context into its
2857 own file, not accesible to application. Affected files
2858 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2859 and other files in client library.
2861 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Added doc/examples installation target in Makefile.am.pre.
2866 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2869 commands the found client entry will be removed from the
2870 cache, after notifying application about the error. Affected
2871 file lib/silcclient/command_reply.c.
2873 * Changed the /MSG to check for exact nickname user gave, and
2874 not let `nick' match `nick@host' if it is only one found. Now,
2875 user must type the exact nickname (like nick@host2) even if
2876 there are no more than one same nicks found. This is to avoid
2877 a possibility of sending nickname to wrong nickname since
2878 `nick' could match `nick@host'. Affected file is
2879 irssi/src/core/silc-servers.c.
2881 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Do not print "you are now server operator" or similar when
2884 giving /away command. Affected files are
2885 irssi/src/silc/core/client_ops.c, silc-servers.h.
2887 * Made the silc_server_command_pending_error_check to send
2888 the same command reply payload it received back to the
2889 original sender of the command. This way all arguments
2890 that was received by the server will be received by the
2891 client too. Affected file silcd/command.c.
2893 * Added the silc_idcache_add to return the created cache entry
2894 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2896 * Add global clients to expire if they are not on any channel.
2897 This is because normal server will never know if they signoff
2898 if they are not on any channel. The cache expiry will take
2899 case of these entries. This is done by normal servers only.
2900 The affected files are silcd/command_reply.c,
2901 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2903 * If server receives invalid ID notification for WHOIS or
2904 IDENTIFY and the ID exists in the lists, it is removed.
2905 Affected file silcd/command_reply.c.
2907 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2908 in client then client entry that it matches is searched and
2909 the nickname is printed on the screen for user. Affected
2910 file irssi/src/silc/core/client_ops.c.
2912 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Use cache entry expire time in the LIST command reply to
2915 purge old entries from the cache after the LIST command
2916 reply has been received. This way we don't have non-existent
2917 entries in the cache for too long. Affected file is
2918 silcd/command_reply.c.
2920 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * If we are normal server, and we've not resolved client info
2923 in WHOIS or IDENTIFY from router, and it is global client,
2924 we'll check whether it is on some channel. If it is not
2925 then we cannot be sure about its validity and will resolve it
2926 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2927 file silcd/command.c.
2929 * Search channel by name (if possible) rather than by ID
2930 in IDENTIFY command's command reply. Affected file is
2931 silcd/command_reply.c.
2933 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2936 Updated specs and implemented it. Affected file silcd/command.c,
2937 silcd/packet_send.c and silcd/packet_receive.c.
2939 * Implemented the <founder auth> payload handling in the JOIN
2940 command. If provided all conditions for channel joining
2941 except requirement to provide correct passphrase can be
2942 overrided by the channel founder. Updated the protocol specs.
2943 Affected file silcd/command.c.
2945 Added support for founder auth in JOIN command in client
2946 library. Fixed the parsing of the JOIN command now to support
2947 all options as they should be. The affected file is
2948 lib/silcclient/command.c.
2950 * Optimized the WHOIS and IDENTIFY commands to send the request
2951 to router only if it includes nicknames or other names. If
2952 they include only IDs then check the local cache first before
2953 routing. Affected file is silcd/command.c.
2955 * Added channels topic announcements. Affected file is
2956 silcd/packet_receive.c and silcd/server.c.
2958 * Fixed the silc_server_send_notify_topic_set to really destine
2959 the packet to channel. Affected file silcd/packet_send.c.
2961 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2962 library. Affected file lib/silcclient/client_notify.c.
2964 * Added UMODE announcements. Affected file silcd/server.c.
2966 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Memory leak fixes in:
2970 lib/silcutil/silcsockconn.c
2971 lib/silcske/silcske.c
2972 lib/silcske/groups.c
2974 lib/silccrypt/silcpkcs.c
2975 lib/silccore/silccommand.c
2976 lib/silccore/silcidcache.c
2981 * ROBOdoc documented the lib/silcske/groups.h file and a
2982 bit changed the interface for better.
2984 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2986 * Update the client entry context in the ID cache after
2987 nick change. Affected file lib/silcclient/command.c.
2988 Fixes the CUMODE command when regaining founder privileges,
2989 and a little WHOIS problem.
2991 * Fixed silc_net_gethostbyname to correctly call the
2992 inet_ntop. Affected file lib/silcutil/silcnet.c.
2994 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2996 * Added IPv6 support checking to the configure.in.pre, added
2997 also --enable-ipv6 option to override the check. Affected
2998 file configure.in.pre.
3000 * The silc_thread_create now calls the start function
3001 directly if threads support is not compiled in. Removes
3002 ugly #ifdef's from generic code. Affected files are
3003 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3005 * Added silc_net_gethostby[name/addr]_async to asynchronously
3006 resolve. Affected files are lib/silcutil/silcnet.[ch].
3008 * Added support for rendering IPv6 based server, client and
3009 channel IDs. Affected file lib/silcutil/silcutil.c.
3011 * Added support for creating IPv6 based server IDs. Affected
3012 file is silcd/serverid.c.
3014 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3016 * Added silc_net_gethostby[addr/name] into the
3017 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3018 routines. Added silc_net_is_ip[4/6]. Affected file is
3019 lib/silcutil/unix/silcunixnet.c. All routines that take
3020 address as argument now supports both IPv4 and IPv6 addresses.
3022 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3024 * Fixed LIST command reply sending in server. Affected file
3027 * Server now sends the kicker's client ID in the KICK notify
3028 to the kicked client. Affected file silcd/command.c.
3030 * The client library now parses the kickers client ID and
3031 UI displays it. Affected files lib/silcclient/client_notify.c
3032 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3034 * Made all payload parsing function prototypes consistent.
3035 They all take now const unsigned char * and uint32 pair as
3036 the payload data instead of SilcBuffer. Changes all around
3037 the source tree. Other unsigned char* -> const unsigned char*
3038 changes around the tree as well.
3040 * Optimized SFTP client and server packet sending not to
3041 allocate new buffer for each packet but to recycle the
3042 first allocated buffer. Affected files are
3043 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3045 * Optimized the SFTP client to use SilcList instead of
3046 SilcDList for requests, because it is faster. Affected file
3047 is lib/silcsftp/sftp_client.c.
3049 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3050 into lib/silccore/silcid.[ch].
3052 Renamed silcpayload.[ch] into silcargument.[ch].
3054 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3056 * If client entry is deleted with active key agreement
3057 session, abort the session.
3059 The silc_client_abort_key_agreement now calls the completion
3060 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3062 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3065 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Don't use __restrict in older GCC's. Affected file is
3068 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3070 * silc_net_localhost now attempts to reverse lookup the
3071 IP/hostname. Affected file lib/silcutil/silcnet.c.
3073 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3074 command. It can be used to gain founder privileges at
3075 the same time when joining the channel.
3077 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3078 kicker's client ID as well. Updated protocol specs.
3080 Defined that the server must send SILC_COMMAND_IDENTIFY
3081 command reply with error status to client who sent
3082 private message with invalid client ID.
3084 Updated the protocol specification.
3086 * Added silc_server_send_command_reply to send any
3087 command reply. Affected file silcd/packet_send.[ch].
3089 * Added silc_id_payload_encode_data to encode ID payload
3090 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3092 * The server now send IDENTIFY command reply with error
3093 status if client ID in private message is invalid. Affected
3094 file silcd/packet_receive.c.
3096 * Save the server key file with server's IP address in
3097 the filename instead of hostname. The affected file is
3098 irssi/src/silc/core/client_ops.c.
3100 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3105 * Added libtool support for compiling shared objects in
3106 lib/silcsim. Affected file configure.in.pre and
3107 lib/silcsim/Makefile.am. Original patch by cras.
3109 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Pid file configuration, and server's config file fixes
3112 patch by toma. Updated CREDITS file.
3114 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Fixed silc_client_channel_message to not try to decrypt
3117 the message twice if it resolved the destination client
3118 information. This could cause of dropping one channel
3119 message. Affected file lib/silcclient/client_channel.c.
3121 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3123 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3124 lib/silcclient/client.c. This function is used when the SILC
3125 Client is run under some other scheduler, or event loop or
3126 main loop. On GUI applications, for example this may be
3127 desired to used to run the client under the GUI application's
3128 main loop. Typically the GUI application would register an
3129 idle task that calls this function multiple times in a second
3130 to quickly process the SILC specific data.
3132 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3134 * Fixed silc_server_drop() for dropping the supplementary
3135 groups as well, this could cause a security hole on some
3138 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3143 * Write PID file after dropping privileges. Added -F option
3144 to run server on foreground. A patch by debolaz.
3145 Affected files silcd/server.c, silcd/silcd.c.
3147 * Fixed MOTD to return the MOTD file server name. Affected
3148 file silcd/command.c.
3150 * Added INFO command reply handling to the Irssi SILC Client.
3151 Affected file irssi/src/silc/core/client_ops.c.
3153 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Fixed the silc_idcache_list_* routines to really support
3156 the dynamic list. Fixes a crash. Affected file is
3157 lib/silccore/silcidcache.c.
3159 * Fixed the LIST command reply to really call LIST command's
3160 pending callbacks. Affected file silcd/command_reply.c.
3162 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3164 * Update conn->local_entry->nickname after giving NICK
3165 command. Affected file lib/silcclient/command.c.
3167 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3169 * Added the [pid] option to the silcd configuration file
3171 Affected files: serverconfig.[ch] and silcd.c
3173 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3175 * Save fingerprint in WHOIS command reply in server.
3176 Affected file silcd/command_reply.c.
3178 * Fixed NICK commands pending callback registration.
3179 Affected file lib/silcclient/command.c.
3181 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3183 * Use ++server->cmd_ident when sending commands in server,
3184 instead of random number. Affected file silcd/command.c.
3186 * Fixed GETKEY command reply to call actually GETKEY pending
3187 command callbacks. Affected file silcd/command_reply.c.
3189 * A bit stricter check for nicknames. Check for same nickname
3190 in NICK command also. Affected file silcd/command.c.
3192 * Do not call INFO command everytime client ID changes, only
3193 during first connecting. Affected file lib/silcclient/client.c.
3195 * Set the new nickname only after successful command reply for
3196 NICK command is returned by server. Affected file
3197 lib/silcclient/command.c.
3199 * Remove nicknames from nicklist during server_signoff notify.
3200 Should fix /NAMES bit more. The affected file is
3201 irssi/src/silc/core/silc-channels.c.
3203 * Added `fingerprint' field to the SilcIDListData in the
3204 silcd/idlist.h to hold the fingerprint of the client's
3207 Send the fingerprint of the client's public key in WHOIS
3210 Affected files silcd/command.c, and silcd/idlist.[ch].
3212 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3213 create fingerprint from given data.
3215 * Show the fingerprint of the client's public key in WHOIS.
3216 Affected files irssi/src/module-formats.[ch] and
3217 irssi/src/silc/core/client_ops.c.
3219 * Format the multiple same nicknames also during JOIN and
3220 NICK_CHANGE notifys. Affected file is
3221 lib/silcclient/client_notify.c.
3223 * Do not print error on screen for invalid private message
3224 payload since it can come if someone is sending private
3225 messages with wrong key. Affected file
3226 lib/silccore/silcprivate.c.
3228 * Fixed multiple concurrent /PING crash. Affected file
3229 lib/silcclient/command.c.
3231 * Changed the wrong ID encoding. All IP addresses must be
3232 in MSB first order in encoded format. They were encoded
3233 wrong and was in LSB format. Affected files are
3234 silcd/serverid.c, lib/silcutil/silcutil.c.
3236 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3238 * Call the `connect' client operation through the scheduler
3239 in case of error. Affected file lib/silcclient/client.c.
3241 * Call the `failure' client operation even if the error
3242 occurred locally during a protocol. Affected file is
3243 lib/silcclient/protocol.c.
3245 * Added support of sending LIST command to router from normal
3246 server. This way normal server can get list of all channels
3247 in the network too. Fixed the channel list sending in the
3248 server too. Affected files are silcd/command.c, and
3249 silcd/command_reply.[ch].
3251 * Added silc_server_update_channels_by_server and
3252 silc_server_remove_channels_by_server. They are used during
3253 disconnection of primary router and in backup router protocol.
3254 Affected file silcd/server_util.[ch], silcd/server.c and
3255 silcd/server_backup.c.
3257 * Fixed channel adding to global list in IDENTIFY command
3258 reply in server. Affected file silcd/command_reply.c.
3260 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * If the incoming packet type is REKEY or REKEY_DONE process
3263 that packet always synchronously. Fixes yet another MAC
3264 failed error on slow (dialup) connections. Affected file
3265 lib/silcclient/client.c and silcd/server.c.
3267 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Call check_version SKE callback for initiator too. Affected
3270 file lib/silcske/silcske.c.
3272 * Implemented fix for security hole found in the SKE that was
3273 fixed in the specification few days back; the initiator's
3274 public key is now added to the HASH value computation.
3275 Added backwards support for the old way of doing it too, for
3276 old clients and old servers. Affected file is
3277 lib/silcske/silcske.c.
3279 * Enabled mutual authentication by default in SKE. If initiator
3280 is not providing mutual authentication the responder will
3281 force it. This will provide the proof of posession of the
3282 private key for responder. The affected files are
3283 lib/silcclient/protocol.c and silcd/protocol.c.
3285 * Do not cache anymore the server's public key during SKE.
3286 We do mutual authentication so the proof of posession of
3287 private key is done, and if the server is authenticated in
3288 conn auth protocol with public key we must have the public
3289 key already. Affected file silcd/protocol.c.
3291 * Added new global debug variable: silc_debug_hexdump. If
3292 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3293 file lib/silcutil/silclog.[ch].
3295 * Fixed compilation warning due to char * -> const char *.
3296 Affected files lib/silcutil/silcnet.h, and
3297 lib/silccore/silcauth.[ch].
3299 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Fixed CMODE command when new channel key was created. If
3302 the creation failed the old key was removed. Next time giving
3303 same command would crash the server since the old key was
3304 freed already. Affected file silcd/command.c.
3306 * Fixed the silc_server_announce_get_channels to not crash
3307 on reconnect. Affected file silcd/server.c.
3309 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Added silc_log_set_debug_string function to set a regex
3312 string to match for debug output. Only the function names,
3313 or filenames matching the given debug string is actually
3314 printed. This way it is possible to filter out those debug
3315 strings that user is not interested in.
3317 Fixed a bug in silc_string_regexify.
3319 Affected files lib/silcutil/silclog.[ch], and
3320 lib/silcutil/unix/silcunixutil.c.
3322 * Changed the -d options in both server and Irssi SILC client
3323 to take the debug string as argument. Affected files
3324 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3326 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3328 * Added silc_hash_babbleprint to create a Bubble Babble
3329 Encoded fingerprint. The encoding is developed by Antti
3330 Huima (draft-huima-babble-01.txt), and it creates human
3331 readable strings out of binary data. Affected file
3332 lib/silccrypt/silchash.[ch].
3334 * Print the babble print now in addition of fingerprint as well
3335 in Irssi SILC client. Affected files are
3336 irssi/src/fe-common/silc/module-formats.[ch],
3337 irssi/src/fe-common/silc/core/client_ops.c.
3339 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3341 * Fixed a security problem found in SKE. The initiator's
3342 public key too is now added to the HASH hash value creation
3343 which is signed by the responder to create the SIGN value.
3344 This will prevent anyone in the middle to lie to the responder
3345 about the initiator's public key. If this is done now, the
3346 man in the middle will get caught. Updated the protocol
3349 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Better installation directory handling. Configure module
3352 paths and other paths automatically to example_silc* files
3353 in doc/. A patch by toma.
3355 * Fixed compiler warning from MPI library, and from SILC RNG.
3358 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3359 It can be configured with ./configure. A patch by toma.
3361 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Find correct make to use in prepare-clean. A patch by
3364 toma. Affected file prepare-clean.
3366 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3368 * Added irssi variables use_auto_addr, auto_bind_ip,
3369 auto_bind_port and auto_public_ip.
3371 * Changed the interface for silc_client_send_key_agreement
3372 in lib/silcclient/silcapi.h
3376 irssi/src/silc/core/silc-core.c
3378 lib/silcclient/silcapi.h
3379 irssi/src/silc/core/silc-channels.c
3380 lib/silcclient/client_keyagr.c
3383 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Added silc_pkcs_public_key_compare to compare two
3386 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3388 * Check that the client who set the founder mode on the
3389 channel is the same client that is giving the founder
3390 mode to itself. It is done by comparing the saved public
3391 key (it is saved even in the authentication is passphrase).
3392 Affected file silcd/command.c.
3394 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3396 * Do not process packet for disconnected socket connection.
3397 Affected file lib/silccore/silcpacket.c.
3399 * Process the DISCONNECT packet through scheduler in the
3400 client library. Affected file lib/silcclient/client.c.
3402 * Fixed the silc_client_packet_parse to not to increase
3403 the packet sequence number if the conn->sock and the
3404 current socket connection is not same. This can happen
3405 for example during key agreement when the conn includes
3406 multiple socket connections (listeners). Affected file
3407 lib/silcclient/client.c.
3409 * The sender of the file transfer request now provides also
3410 the pointer (listener) for the key exchange protocol. If
3411 the listener cannot be created then it sends empty key
3412 agreement and lets the receiver provide the listener.
3414 Added `local_ip' and `local_port' arguments to the
3415 silc_client_file_send. If they are provided they are used,
3416 if not then it will attempt to find local IP address, if
3417 not found or bind fails then the remote client will provide
3420 Affected files are lib/silcclient/client_ftp.c and
3421 lib/silcclient/silcapi.h.
3423 * Extended the FILE SEND command to support defining the
3424 local IP and port for key exchange listener. They are
3425 optional. Affected file irssi/src/silc/core/silc-servers.c.
3427 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3429 * Defined to WHOIS command reply the sending of fingerprint
3430 of the client's public key (if the proof of posession of the
3431 corresponding private key is verified by the server).
3432 Updated to the protocol specification.
3434 * Added support of receiving the client's public key's
3435 fingerprint in command reply in client library. Affected
3436 file is lib/silcclient/command_reply.c, and
3437 lib/silcclient/idlist.[ch].
3439 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Do not send over 128 chars long nickname to the server
3442 in NICK command. Affected file lib/silcclient/command.c.
3444 * Do not send over 256 chars long channel names to the server
3445 in JOIN command. Affected file lib/silcclient/command.c.
3447 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3449 * Assure that silc_server_close_connection cannot be called
3450 twice for same socket context. Affected file is
3453 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Send error message to application if opening file for
3456 writing during file transfer fails. Affected file is
3457 lib/silcclient/client_ftp.c.
3459 Remove all file transfer sessions for a client that we're
3460 removing from ID cache.
3462 Affected file is lib/silcclient/client_ftp.c.
3464 * Fixed silc_net_addr2bin to return correct address. Affected
3465 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3467 * Fixed file transfer session removing on signoff notify.
3468 Affected file irssi/src/silc/core/silc-servers.c.
3470 * Added the SilcClientFileError to be returned in the monitor
3471 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3472 Affected file lib/silcclient/silcapi.h.
3474 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3476 * Fixed a crash in silc_client_ftp_free_sessions and
3477 silc_client_ftp_session_free_client. Affected file
3478 lib/silcclient/client_ftp.c.
3480 * Added `disabled' field in the SilcChannelEntry in the server
3481 to indicate if the server entry is disabled. Affected file
3482 silcd/idlist.h, silcd/command[_reply].c.

3488 the provided table of client entries. Affected file
3489 silcd/packet_send.[ch].
3491 * Fixed a crash in client resolving in client_prvmsg.c in
3492 client library. Affected file lib/silcclient/client_prvmsg.c.
3494 * Do not actually remove the client directly from ID cache
3495 during SERVER_SIGNOFF, but invalidate it. This way we
3496 preserve the WHOWAS info for the client. Affected file
3497 silcd/server_util.c.
3499 * Fixed SERVER_SIGNOFF notify handling in the server. The
3500 server is now able to process incoming SERVER_SIGNOFF notify
3501 for a server that it doesn't even know about. It will remove
3502 the clients provided in the notify. Affected file
3503 silcd/packet_receive.c.
3505 * Check for partial packet in data queue after every packet that
3506 was found from the queue. Return and wait for more data if
3507 there is partial data in queue. Affected file is
3508 lib/silccore/silcpacket.c.
3510 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3514 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3515 Affected files lib/silcclient/silcapi.h and
3516 lib/silcclient/client_ftp.c.
3518 * Check that newsize in silc_buffer_realloc is larger than
3519 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3521 * Added better monitor of file transfers. It now monitors
3522 key agreement protocol during the file transfer too. Added
3523 error reporting too. Affected files
3524 irssi/src/silc/core/silc-servers.c,
3525 irssi/src/fe-common/silc/module-formats.[ch].
3527 * Wrote a help file for FILE command.
3529 * Added silc_rng_global_get_byte_fast to get not-so-secure
3530 random data as fast as possible. Random data is read from
3531 /dev/urandom if available and from the SILC RNG if not
3532 available. It is used in padding generation. Affected file
3533 lib/silccrypt/silcrng.[ch].
3535 * All packets in client library are now processed synchronously.
3536 Optimized packet processing a lot. Affected file
3537 lib/silcclient/client.c.
3539 * All server connection packets are processing synchronously
3540 now in server, to optimize packet processing. Affected file
3543 * Include files are installed now only in Toolkit distribution
3544 if make install is given. Affected files: all Makefile.am's.
3546 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Assure that silc_client_notify_by_server_resolve does not
3549 resolve the client information multiple times. If it cannot
3550 be found by the first it cannot be found at all. Affected
3551 file lib/silcclient/client_notify.c.
3553 * Fixed WHOWAS command reply calling. Affected file
3554 lib/silcclient/command_reply.c.
3556 * Removed all references to silc_idlist_get_client from the
3557 Irssi SILC client since that call is internal call used by
3558 the library. The Irssi SILC client will use now client
3559 retrieval functions found in silcapi.h.
3561 * Fixed a bug in resolving nickname info before sending
3562 private message. It used freed memory. Affected file
3563 irssi/src/silc/core/silc-servers.c.
3565 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Assure my_channels statistics cannot go negative in server.
3568 Affected files silcd/server.c, silcd/server_util.c.

3584 * Added silc_net_localip to return local host's IP address.
3585 Affected file lib/silcutil/silcnet.[ch].
3587 * If key exchange or rekey protocol is active for a connection
3588 parse all packets syncronously since there might be packets
3589 in packet queue that we are not able to process without first
3590 processing packets before them. Affected file silcd/server,
3591 lib/silcclient/client.c.
3593 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3594 whether library should continue processing the packet.
3595 Affected file lib/silccore/silcpacket.h.
3597 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3645 Make sure also that USERS command reply does not resolve
3646 twice information. Affected file is
3647 lib/silcclient/command_reply.c.
3649 Make sure that silc_client_get_clients_by_list does not
3650 resolve twice same information.
3652 * Check for valid client->id in the silc_server_free_client_data.
3653 Affected file silcd/server.c.
3655 * Fixed /GETKEY nick@server not to crash if the server entry
3656 is not found. Affected file lib/silcclient/command.c.
3658 * Fixed the silc_server_check_cmode_rights to check the

3664 Affected file silcd/command.c.
3666 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3668 * Call the silc_server_udpate_servers_by_server in the
3669 primary router that comes back online in the backup resuming
3670 protocol. Otherwise it routes packets wrong. Affected file
3671 silcd/server_util.[ch], silcd/server_backup.c.
3673 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3676 lib/silcutil/silcbuffmt.[ch].
3678 * Redefined the SILC packet header to include the padding
3679 length. Affected file lib/silccore/silcpacket.[ch].
3681 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3682 length for maximum padding up to 128 bytes). Affected
3683 file lib/silccore/silcpacket.h.
3685 * Removed all backwards support for old 0.5.x MAC thingies.
3686 The SILC packet header change makes it impossible to be
3687 backwards compatible.
3689 * Send the ENDING packet with timeout in the backup resuming
3690 protocol. This is to assure that all routers has connected
3691 to the primary router. Affected file silcd/server_backup.c.
3693 * Changed the RNG to take the first IV from random data. It
3694 used to take it from zero actually. Changed the RNG also
3695 to use /dev/urandom during session. /dev/random is used
3696 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3698 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3700 * Changed the SILC packet header to have the first two bytes
3701 (the packet length) encrypted. Affected files aroung the
3702 code tree, lib/silccore/silcpacket.[ch]. Removed the
3703 SilcPacketCheckDecrypt callback. It is not needed anymore
3704 since the silc_packet_receive_process will determine now
3705 whether the packet is normal or special.
3707 * Implemented the unidirectional MAC keys. Affected files
3708 lib/silcske/silcske.c, silcd/protocol.c and
3709 lib/silcclient/protocol.c.
3711 * Implemented the packet sequence number to the MAC computation.
3712 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3713 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3714 lib/silcclient/protocol.c.
3716 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3718 * Allow backup router to announce servers. All servers
3719 announced by backup router are added to the global list
3720 automatically. Update hte server's socket to our primary
3721 router also when backup router announces a server.
3722 Affected file silcd/packet_receive.c.
3724 * Do not update the client->router in the function
3725 silc_server_udpate_clients_by_server if the client is on
3726 global list. We might fail to find any specific server
3727 for locally connected clients and local cell clients. They
3728 should still use the `from' and not `to' as client->router.
3729 This fixes backup router resuming protocol. Affected file
3730 silcd/server_util.c.
3732 * Decrease channel statistics count only if the channel
3733 deletion worked. Affected files are silcd/server.c and
3734 silcd/server_util.c.
3736 * Added silc_server_update_servers_by_server to update origin
3737 of all server entries. Used during backup router protocol.
3738 Affected files silcd/server_util.[ch], silcd/server.c. and
3739 silcd/backup_router.c.
3741 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3742 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3743 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3744 lib/silccrypt/silchmac.c.
3746 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3748 * Assure that router cannot reroute the same channel message
3749 to the sender. Affected file silcd/packet_receive.c.
3751 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3753 * Made better checks that the channel message is not sent
3754 to the router it came from. Affected file is
3755 silcd/packet_send.c. Fixed memory leak too.
3757 * Announce informations for incoming router connection, but
3758 only after checking if it is replaced by backup router.
3759 Affected file silcd/packet_receive.c.
3761 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * Fixed the backup resuming protocol to work in multiple
3764 router environment. Affected file silcd/server_backup.c.
3766 * Route packet only to one router in the function
3767 silc_server_packet_send_to_channel. Affected file is
3768 silcd/packet_send.c.
3770 * Fixed silc_server_send_notify_dest to set the broadcast
3771 flag. Fixed the silc_server_send_notify_topic to actually
3772 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3773 Affected file silcd/packet_send.c.
3775 * Changed the SFTP Filesystem interface. Changed the
3776 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3777 the filesystem operation function. The SilcSFTPFilesystem
3778 is now a context that is allocated by all filesystem allocation
3779 functions and it already includes the operations structure
3780 and filesystem specific context. It is given as argument
3781 now to the silc_sftp_server_start. This made the interface
3782 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3783 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3785 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3787 * Changed the backup router adding and getting interfaces
3788 in the server. The router that will be replaced by the
3789 specified backup router is now sent as argument. Affected
3790 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3793 * Added silc_net_addr2bin_ne to return the binary form of
3794 the IP address in network byte order. Affected files
3795 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3797 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Check for existing server ID in silc_server_new_server
3800 and in silc_server_connect_to_router_final and remove the
3801 old entry if it exists. Affected file silcd/packet_receive.c,
3804 * Send the channel message always to only one router, either
3805 in upstream or downstream. Affected file is
3806 silcd/packet_send.c.
3808 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Wrote the definition of the backup resuming protocol to the
3811 protocol specification.
3813 * Removed one redundant channel key generation from normal
3814 server during joining procedure. Removed one redundant
3815 channel key sending from server to router during joining
3816 procedure. Affected file silcd/command.c.
3818 * Made minor bugfixes to the backup router resuming protocol.
3819 Affected file silcd/server_backup.c, server.c.
3821 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * Added --disable-asm configuration option. Affected files
3824 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3827 * Implemented the backup resuming protocol that is used to
3828 resume the primary router position in the cell after the
3829 primary router comes back online. Affected files
3830 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3831 and silcd/server_util.[ch].
3833 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Sleep two (2) seconds after sending QUIT command to server.
3836 Affected file lib/silcclient/command.c.
3838 * Assure that if outgoing data buffer is pending do not force
3839 send any data. Affected file silcd/packet_send.c.
3841 * Assure that if outgoing data buffer is pending do not force
3842 send any data. Affected file lib/silcclient/client.c.
3844 * Implemented the backup router support when the primary router
3845 goes down. The servers and routers can now use the backup
3846 router as new primary router without loosing connectivity.
3848 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3851 in the server to indicate disabled entry. All data read
3852 from the connection will be ignored and no data is sent
3853 for entry that is disabled. Affected files are
3854 silcd/idlist.h, silcd/server.c.
3856 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3858 * Created SFTP client and server test programs in the
3859 lib/silcsftp/tests directory.
3861 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Implemented memory filesystem (virtual filesystem) for
3864 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3867 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3869 * Implemented the SFTP (SSH File Transfer Protocol) to the
3870 lib/silcsftp. It includes SFTP client and SFTP server
3873 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3875 * Moved lib/silccore/silcprotocol.[ch] to the
3876 lib/silcutil library.
3878 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3879 take variable argument list pointer as argument. Affected
3880 file lib/silcutil/silcbuffmt.[ch].
3882 * Added silc_buffer_set function that is used to set data
3883 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3884 Affected file lib/silcutil/silcbuffer.h.
3886 * Changed various routines in the core library to use the new
3887 silc_buffer_set instead of allocating new buffer only for
3890 * Added 64-bit value formatting and unformatting support to the
3891 silc_buffer_[un]format routines. Affected file is
3892 lib/silcutil/silcbuffmt.[ch].
3894 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3895 to includes/bitmove.h.
3897 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3899 * Fixed channel user mode saving in client library. Affected
3900 file lib/silcclient/command[_reply].c.
3902 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3904 * Defined the file transfer to the SILC Protocol. Added
3905 new packet type SILC_PACKET_FTP and defined File Transfer
3906 Payload. The mandatory file transfer protocol is SFTP
3907 (SSH File Transfer Protocol). Affected file in addition
3908 of the internet draft is lib/silccore/silcpacket.h.
3910 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3911 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3912 is used as part of backup router protocol when the primary
3913 router of the cell is back online and wishes to resume
3914 the position as primary router.
3916 * Redefined the MAC generation keys in the protocol. The
3917 same key is not used anymore in both direction. Both
3918 direction will now use different keys for sending and
3919 receiving. This fixes a potential security flaw. This
3920 change causes incompatibilities in the protocol.
3922 * Redefined also the MAC computation from the packet.
3923 An packet sequence number is now added to the MAC
3924 computation. This prevents possible replay attacks against
3925 the protocol. This change too causes incompatibilities
3928 Added `sequence' field to the SilcPacketContext to hold
3929 the current sequence number for the packet.
3931 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Added `created' field to the SilcIDListData in the file
3934 silcd/idlist.h to indicate the time when the entry was
3937 * Added `created' field to the SilcChannelEntry too. Affected
3938 file silcd/idlist.h.
3940 * Added `creation_time' aguments to all the announcement functions
3941 in the server. If it is provided then only the entries that
3942 was created after the provided time frame are actually
3943 announced. Affected file silcd/server.[ch].
3945 * The protocol says that the Channel ID's IP address must be
3946 based on the router's IP address. Added check for this in
3947 the silc_server_new_channel when processing incoming New Channel
3948 Payload. Affected file silcd/packet_receive.c.
3950 * Print out the correct version with --version in SILC client.
3951 Affected file irssi/src/silc/core/silc-core.c.
3953 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3955 * Fixed WHOWAS command to check for completnes of the client
3956 entry always, not just when the command is coming from client.
3957 Affected file silcd/command.c.
3959 * Added new function silc_server_packet_queue_purge to purge the
3960 outgoing data queue to the network. After the function returns
3961 it is guaranteed that the outgoing packet queue is empty.
3962 Affected file silcd/packet_send.[ch].
3964 * Purge the outgoing packet queue in the rekey protocol's final
3965 callback to assure that all rekey packets go to the network
3966 before quitting the protocol. Affected file silcd/server.c.
3968 * Added silc_client_packet_queue_parse as similar function as
3969 in server to the client library. The affected file is
3970 lib/silcclient/client.c.
3972 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3974 * Splitted silcd/server.c and created silcd/server_util.[ch]
3975 for utility functions.
3977 * Added new socket flag SILC_SF_DISABLED to indicate that the
3978 connection is open but nothing can be sent to or received from
3979 the connection. Affected file lib/silcutil/silsockconn.[ch].
3980 The checking for disabled socket is checked in the low level
3981 silc_socket_write and silc_socket_read functions.
3983 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3985 * Allow only nicknames and channel names that fits into the
3986 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3988 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3990 * When processing JOIN command reply in server check that if
3991 the channel exists in our global list we'll move it the local
3992 list. Affected file silcd/command_reply.c.
3994 * Fixed the check whether client is joined on the channel already
3995 in JOIN command. Affected file lib/silcclient/command.c.
3997 * Fixed the JOIN command reply to check whether the channel
3998 already exists. Affected file lib/silcclient/command_reply.c.
4000 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * Added silc_ske_status_string to map the SKE error numbers
4003 to readable strings. The affected files are
4004 lib/silcske/silcske[_status].[ch].
4006 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4008 * Do not show the private channels on the WHOIS channel list
4009 as it is not allowed by the protocol. The affected file is
4012 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4014 * Assure that the packet length digged from the actual packet
4015 is something sensible in the silc_packet_decrypt_rest_special
4016 in lib/silccrypt/silcpacket.c.
4018 * Free and NULL the allocated pointer in silc_hmac_alloc if
4019 the HMAC allocation fails. The affected file is
4020 lib/silccrypt/silchmac.c.
4022 * Print the selected security properties to the log files in
4023 the server. Affected file silcd/protocol.c.
4025 * Add SKE's reference counter even if calling the completion
4026 callback manually. Otherwise it goes negative, although it
4027 does not cause any problems. The affected file is
4028 lib/silcske/silcske.c.
4030 * Remove the client entry with short timeout after giving the
4031 KILL command. Affected file lib/silcclient/command.c.
4033 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4034 case all found clients are already disconnected (WHOWAS would
4035 found them) in the server. Affected file silcd/command.c.
4037 * Update the last_receive (time of last data received) to be
4038 updated only when received private or channel message so that
4039 the idle time showed in WHOIS makes more sense.
4041 * Added boolean field `valid' in to the SilcClientEntry in the
4042 client library to indicate whether the entry is valid or not.
4043 This fixes the nickname change bug on channel when changing
4044 the nickname to be same than the old (like nick to Nick) the
4045 nickname formatter doesn't set the new nick anymore to Nick@host.
4046 Affected file lib/silcclient/idlist.[ch].
4048 * Now actually fixed the nickname changing on disconnection.
4049 Added new function silc_change_nick to the Irssi SILC Client.
4050 Affected file irssi/src/silc/core/client_ops.c,
4051 irssi/src/silc/core/silc-nicklist.[ch].
4053 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4055 * Check that the public key exists in the GETKEY command before
4056 trying to encode it. Affected file silcd/command.c.
4058 * Print some notifications on received public keys with GETKEY
4059 command in the Irssi SILC Client. Affected files are
4060 irssi/src/fe-common/silc/module-formats.[ch],
4061 irssi/src/silc/core/client_ops.c.
4063 * Use IDENTIFY command to resolve the server information in the
4064 GETKEY command instead of INFO command. Affected file
4065 lib/silcclient/command.c.
4067 * All command reply functions in the client library now calls
4068 the pending command reply callbacks even if an error has
4069 occurred. The server has done this a long time and now it was
4070 time to move the client library to this as well. Now all
4071 errors can be delivered back to the pending command reply
4072 callbacks if necessary. Affected files are
4073 lib/silcclient/command[_reply].[ch].
4075 * Change the nickname on disconnection back to the username
4076 because in reconnect the server will enforce it to it anyway.
4077 Affected file irssi/src/silc/core/silc-servers.c.
4079 * Fixed a config file parsing bug in the Irssi SILC client.
4080 Affected file irssi/src/silc/core/clientconfig.c.
4082 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * When printing the channel mode on JOIN, verify that the
4085 channel key and channel's HMAC are valid. Affected file
4086 irssi/src/silc/core/client_ops.c.
4088 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4090 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4091 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4092 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4094 * Removed channel key rekey task deleting from the function
4095 silc_server_save_channel_key. Affected file silcd/server.c.
4096 Added explicit timeout task context instead that is used to
4097 delete the task if we are registering a new task before the
4098 new task has elapsed.
4100 * When channel key rekey occurs the client library now saves
4101 the old channel key for a short period of time (10 seconds) and
4102 is able to use it in case some is still sending channel
4103 messages encrypted with the old key after the rekey. Affected
4104 file lib/silcclient/[idlist.h|client_channel.c].
4106 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4108 * Added check to the silc_server_new_id_real to not accept
4109 new ID if it is the sender's own ID. Affected file is
4110 silcd/packet_receive.c.
4112 * Assure that we do not announce ourself or the one we've
4113 sending our announcements when we're router and are announcing
4114 servers to our primary router. Affected file silcd/server.c.
4116 * Fixed silc_server_command_identify_check_client to assemble
4117 correct WHOIS packet. It send corrupted WHOIS packet and
4118 caused problem with router to router connections. Affected
4119 file silcd/command.c.
4121 Fixed also silc_server_command_whois_check the same way
4122 as for the IDENTIFY command.
4124 * Added new SilcIDListStatus to the server in the SilcIDListData
4125 structure. The status now includes the current status of
4126 the entry (like registered, resolved etc.). Affected file
4127 silcd/idlist.[ch]. Defined a bunch of different status types
4128 as well. This replaced the old boolean registered field as well.
4130 Added resolve_cmd_ident field to the SilcClientEntry structure
4131 too so that if the entry is for example being resolved so
4132 another command may attach to the same pending command reply
4133 without requiring to resolve the same entry again. This concept
4134 should optimize the WHOIS and the IDENTIFY resolving under
4135 heavy load by taking away unnecessary resolving for entries
4136 that are being resolved already.
4138 Added support for adding multiple pending commands for one
4139 command idenfier. Affected file silcd/command[_reply].[ch].
4141 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4142 before deleting the data. Otherwise the hash table will have
4143 freed data in comparison functions. Affected file is
4144 silcd/command_reply.c.
4146 * Fixed silc_idlist_replace_client_id to add the new entry to
4147 the cache with NULL nickname. Otherwise there will be invalid
4148 memory as the nickname after the nickname is freed. Affected
4149 file silcd/packet_receive.c.
4151 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4152 saved into wrong slots because the previous number of entries
4153 was not taken into account. Affected file silcd/idlist.c.
4154 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4156 * If we are router and we receive JOIN notify to a channel that
4157 does not have any users then notified client is marked as the
4158 channel founder, as it is it. The affected file is
4159 silcd/packet_receive.c
4161 * Added to the extended hash table API's table_del_*ext functions
4162 the destructor as argument too, so that the caller can decide
4163 which destructor to use or whether to use destructor at all.
4164 Affected file lib/silcutil/silchashtable.[ch].
4166 * Fixed ID Cache purging. It actually deleted the entries from
4167 the hash table after the data was freed. The hash table ended
4168 up comparing freed memory. The affected file is
4169 lib/silccore/silcidcache.c.
4171 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4173 * Fixed Irssi SILC client's KILL command's HELP syntax.
4175 * The USERS command now resolves the detailed user information
4176 if the userinfo field is missing. Affected file is
4177 lib/silcclient/command_reply.c.
4179 * Do not print error in silc_file_read if the read file does
4180 not exist. Just silently return NULL. Affected file is
4181 lib/silcutil/silcutil.c.
4183 * Fixed the silc_log_output to not wine about NULL filename
4184 and to not create some bogus " " filename. Affected file is
4185 lib/silcutil/silclog.c.
4187 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4189 * Fixed various printing bugs on the user interface in the
4190 Irssi SILC Client. Minor changes that were forgotten from
4193 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4195 * Fixed the configure.in.pre and the compilation and distribution
4196 environment to support the new autoconf 2.52. That version is
4197 now required to compile the CVS trunk.
4199 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4201 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4202 to generally parse user@fqdn format strings. Affected file
4203 lib/silcutil/silcutil.c.
4205 * Added nickname_format and nickname_force_format fields to the
4206 SilcClientParams structure. The first one defines the format
4207 for the nicknames that the library will enforce if the receives
4208 multiple same nicknames. The second one is boolean value and
4209 can be used to force the library to always enforce the format
4210 to the nicknames regardles whether there are multiple nicknames
4211 or not. This configurable formatting was employed to flexibly
4212 support accessing multiple nicknames from the user interface.
4213 The userinterface can now set the nicknames to what ever format
4214 they prefer. Affected file lib/silcclient/silcapi.h.
4216 Added function silc_client_nickname_format to the file
4217 lib/silcclient/idlist.c. It performs the nickname formatting.
4219 Added new field `hostname´ to the SilcClientEntry context.
4220 It holds the hostname of the client. Affected file is
4221 lib/silcclient/idlist.h.
4223 * Irssi SILC Client sets the nicknames in nick@hostn format.
4224 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4225 irssi/src/silc/core/silc-core.c.
4227 The WHOIS printing now also shows both the real nickname and
4228 the formatted nickname so that user knows how to access the
4229 user if there are multiple same nicknames cached. Affected
4230 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4231 printing formatting too to take the hostname now as a separate
4232 argument. The Affected file is
4233 irssi/src/fe-common/silc/modules-formats.[ch].
4235 * Changed the silc_client_get_clients_local to accept the formatted
4236 nickname as argument. It accepts the real nickname too but the
4237 formatted nickname can be used to find the true entry from
4238 multiple entries. Affected file lib/silcclient/silcapi.h and
4239 lib/silcclient/idlist.c.
4241 * Added nickname_format_parse field to the SilcClientParams.
4242 It is a callback function provided by the application to parse
4243 the nickname out of the formatted nickname string. The library
4244 calls it to get the nickname from the formatted string. Since
4245 the application generally knows better the format of the nickname
4246 string it parses it instead of the library, even though library
4247 encodes the formatted string. If the callback function is not
4248 provided then the library will use the string as is. The
4249 affected file is lib/silcclient/silcapi.h.
4251 * All the nickname strings passed to the client library in
4252 commands are now expected to be formatted nickname strings.
4253 If the command does not support the formatted nickname string
4254 it will assume that the sent string is the actual nickname.
4255 Affected file lib/silcclient/command.c.
4257 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4259 * Added public key authentication support to OPER and SILCOPER
4260 commands in the client library. Affected file is
4261 lib/silcclient/command.c.
4263 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4265 * Changed the get_auth_methdod client operation to be asynchronous.
4266 It can be async if the application resolves the authentication
4267 method from the server during the negotiation. Added new
4268 SilcGetAuthMeth completion callback that the application will
4269 call after resolving the authentication method.
4271 Added function silc_client_request_authentication_method that
4272 the application can use to resolve the authentication method
4273 from the server. Added also SilcConnectionAuthRequest callback
4274 that the library will call after the server has replied. The
4275 application can call this function if it does not know the
4276 current authentication method.
4278 Affected files are lib/silcclient/client.c and
4279 lib/silcclient/silcapi.h.
4281 * The Irssi SILC client now automatically resolves the authentication
4282 method incase any configuration information is not present (and
4283 currently there never is). The affected file is
4284 irssi/src/silc/core/client_ops.c.
4286 * Fixed public key authentication from the client library.
4287 Affected file lib/silcclient/protocol.c. Changed also the
4288 protocol specification about the public key authentication in
4289 the connection authentication protocol. The actual data to be
4290 signed is now computed with a hash function before signing.
4292 * Fixed the public key authentication from the server as well.
4293 Affected file silcd/protocol.c.
4295 * Removed the mlock()'s from the memory allocation routines.
4296 Affected file lib/silcutil/silcmemory.c. The ./configure does
4297 not check anymore for the mlock(). Affected file is
4300 * Fixed USERS command in server to allow the execution of the
4301 command for private and secret channels if the client sending
4302 the command is on the channel. Affected file silcd/command.c.
4304 * Fixed silc_client_get_clients_local to return the clients
4305 count correctly. It could return wrong value. Affected file
4306 lib/silcclient/idlist.c.
4308 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4310 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4311 types. The assembler optimizations seemed not to like 64-bit
4312 data types. The assmebler optimizations thus are now enabled
4313 also for BSD systems as opposed to only enable them for Linux.
4315 * Do not check for threads at all on BSD systems. Affected
4316 file configure.in.pre.
4318 * Removed -n and -h options from the Irssi SILC Client since
4319 they are not used in silc.
4321 * Fixed the prime generation to assure that the first digit
4322 of the generated random number is not zero since our conversion
4323 routines does not like number strings that starts with zero
4324 digit. If zero digit is seen the random number is regenerated.
4325 This caused some corrupted RSA keys when the zero first digit
4326 was met. Affected file lib/silcmath/silcprimegen.c.
4328 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4330 * Fixed WIN32 configuration in the ./configure script.
4331 Fixed to include xti.h on environments that has it.
4332 Patches by Carsten Ilchmann and andrew.
4334 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4336 * Changed the silc_id_create_client_id to be collision
4337 resistant. It is now assured that there cannot be created
4338 two same client ID's. I suspect that some weird bugs in
4339 the server were actually caused by duplicate Client IDs.
4340 Affected file silcd/serverid.[ch]. A router receiving
4341 new ID now also assures and informs the sending server
4342 if the ID caused collision.
4344 * Changed the silc_id_create_channel_id to also assure that
4345 there are no collisions.
4347 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4349 * Statement about ignoring the Mutual Authentication flag when
4350 performing rekey with PFS was a bit misleading. It is ignored
4351 if it was set in the initial negotiation, it cannot be even
4352 set in the rekey. Fixed in the ke-auth draft. Started the
4353 new versions of the protocol drafts in the doc/.
4355 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4357 * Fixed a bug in silc_client_command_identify_save when saving
4358 new channel information. The channel name was no duplicated
4359 and caused crash on exit. Affected file is
4360 lib/silcclient/command_reply.c.
4362 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4364 * Fixed the getkey command handling in the server. Send just
4365 empty OK reply to the sender if the key could not be fetched
4366 (but everything else was ok, like the key just was not available).
4367 Changed the public key parameter to optional in the protocol
4368 specs so that empty OK reply can be sent. Affected file
4371 Added a message to Irssi SILC client to tell to user if the
4372 server did not return a public key.
4374 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * Fixed a channel key regeneration bug. It registered new
4377 timeout tasks exponentially until all system resources were
4378 used. Affected file silcd/server.c.
4380 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4382 * Added the SILC Document generator to the scripts/silcdoc.
4383 It can be used to generate the Toolkit Reference Manual out
4384 of the source tree. Internally it will also use the RoboDoc
4385 generator now imported in util/robodoc.
4387 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4389 * Added couple of return's in rekey protocol if error orccurred
4390 during the protocol. The execution must be terminated.
4391 Affected file silcd/protocol.c. Also, terminate the protocol
4392 always with timeout.
4394 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4396 * The client's Client ID was created initally from the wrong
4397 nickname (it could have been in format nick@host) in the
4398 silc_server_new_client. Affected file silcd/packet_receive.c
4400 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4402 * Added some SILC_LOG_ERROR's to various error conditions
4403 if client could not be added to ID cache. Affected files
4404 silcd/packet_receive.c and silcd/server.c.
4406 * When client's sock->user_data is freed, NULL also the
4407 client->router and client->connection pointers. Added check
4408 for these pointers being NULL to various places around the
4409 code. Affected file silcd/server.c.
4411 * Added client->data.registered == TRUE checks to various
4412 places around the code to assure that unregistered client's
4413 are not handled when it is not allowed. Affected file
4416 * Added `bool registered' fields to all
4417 silc_idlist_[server|client]_get_* routines to indicate whether
4418 the fetched client needs to be registered or not. Affected
4419 file silcd/idlist.[ch].
4421 * Add your own entry as registered to the ID cache in the
4422 server. Affected file server.c.
4424 * Fixed a bug in silc_server_new_server. The SilcServer was
4425 set as the new server's context instead of SilcServerEntry.
4426 This naturally caused some weird bugs.
4428 * Added "updated" field the SilcChannelEntry which indicates
4429 the time since the channel entry was last accessed. This
4430 can be used to determine whether it is necessary to
4431 announce the channel after backup resuming protocol.
4432 Affected files silcd/idlist.[ch].
4434 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4436 * Do not delete the channel rekey task when adding it
4437 for in silc_server_create_channel_key.
4439 * Changed the silc_server_create_channel_key to return
4440 TRUE or FALSE to indicate the success of the channel key
4443 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4445 * Fixed MSVC++ project files and added missing files to
4446 Makefiles under win32/.
4448 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4450 * Do not add TCP_NODELAY flag if the operating system
4451 does not have it defined. Affected files are
4452 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4454 * Fixed buffer overflow from Irssi SILC Client. Affected
4455 file irssi/src/fe-common/core/themes.c.
4457 * Fixed double free in client library in the file
4458 lib/silcclient/client.c when disconnecting from server.
4460 * Applied double free patch from cras to Irssi SILC client.
4461 Affected files irssi/src/core/[modules/expandos].c
4463 * Fixed the disconnection handling to Irssi SILC Client.
4464 The application must call silc_client_close_connection
4465 in ops->connect client operation in case of failure of
4466 the connection. Affected file is
4467 irssi/src/silc/core/client_ops.c.
4469 * Do not set sock->protocol to NULL in the function
4470 silc_client_close_connection after executing the protocol's
4471 final callback since the sock might not be valid anymore.
4472 Affected file lib/silcclient/client.c.
4474 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4476 * Do not enable SILC_THREADS if the linking with libpthread
4477 did not happen. Affected file configure.in.pre.
4479 * Added notion to protocol specification that server must
4480 verify the sent authentication payload with CMODE when
4481 setting the channel founder key. Implemented it to the
4482 server. Affected file silcd/command.c.
4484 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4486 * Added _EXTRA_DIST SILC distribution variable to the
4487 distributions file. It is used to conditionally add extra
4488 files or directories to the specific distribution. Affected
4489 files ./prepare, Makefile.am.pre and distributions.
4491 Removed the `_' from the start of the distribution names.
4494 * Added README.WIN32 for instructions to compile the Toolkit
4497 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4499 * Fixed a double free in disconnection in the server. Affected
4500 file is silcd/server.c.
4502 * Fixed the lib/silcske/groups.c to work now also with GMP
4503 MP library. The string conversion did not work when using
4504 specific base and the base is indicated in the string as well.
4506 * Created win32/ directory which now includes MSVC++ specific
4507 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4508 It will appear only in the toolkit distribution
4510 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4512 * Changed the key material distribution function in case when
4513 the hash output is too short. The data is now concatenated
4514 a bit differently than it used to. Made the change to the
4515 SKE protocol specification.
4517 * Added better GMP detection to configure.in.pre. A patch
4520 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4522 * Fixed a minor bug in SKE that might cause some problem on
4523 some platforms. Affected file lib/silcske/silcske.c.
4525 * Added the cookie checking for initiator in the SKE. It checks
4526 that the responder returns the sent cookie unmodified. The
4527 affected file is lib/silcske/silcske.c. Added new SKE
4528 error type INVALID_COOKIE that can be sent during the
4529 negotiation. Fixed some memory leaks as well.
4531 * Added the "invalid cookie" error message to Irssi SILC client's
4534 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4536 * Added `task_max' field to the SilcClientParams to indicate
4537 the maximum tasks the scheduler can handle. If set to zero,
4538 default values are used. Affected file lib/silcclient/silcapi.h.
4540 * Fixed memory leaks in silc_client_close_connection. Affected
4541 file lib/silcclient/client.c.
4543 * Added silc_client_del_client_entry to client library to free
4544 all memory of given client entry. Affected file is
4545 lib/silcclient/idlist.[ch].
4547 * Added new functions silc_client_del_channel and
4548 silc_client_del_server to delete channel and server entries.
4549 Affected file lib/silcclient/[silcapi.h/idlist.c].
4551 * Removed silc_client_del_client_by_id from silcapi.h.
4553 * Fixed the INFO command to return the server's own info
4554 correctly when querying by Server ID. Affected file is
4557 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4559 * Removed the non-blocking settings in WIN32 code in the
4560 silc_sock_[read/write] and added SleepEx instead. Affected
4561 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4562 of input data is now checked with FIONREAD and ioctlsocket.
4564 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4566 * Call silc_schedule_task_del_by_context in the
4567 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4568 Affected file lib/silccore/silcprotocol.c.
4570 * Call silc_protocol_cancel for active protocols in the
4571 silc_server_close_connection if the funtion
4572 silc_server_free_sock_user_data has not been called.
4573 Affected file silcd/server.c.
4575 * Generic tasks cannot be deleted using the del_by_fd
4576 task deleting function since generic tasks does not match
4577 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4579 * Added a notion to SILCOPER help file that the SILCOPER works
4580 only on router server, not on normal server.
4582 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4584 * Added for WIN32 support for the new scheduler as well.
4585 Affected file lib/silcutil/win32/silcwin32schedule.c.
4587 * Fixed the SHA1 implementation to work on various platforms.
4589 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4591 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4592 API. It is part of the scheduler now. Everything else is
4593 as previously but some functions has changed their names.
4594 Checkout the lib/silcutil/silcschedule.h for the interface.
4595 Updated all applications to use the new interface. Affected
4596 files are lib/silcutil/silcschedule.[ch].
4598 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4600 * Found a bug in the SKE implementation. The HASH value,
4601 specified by the protocol, was not computed correctly. The
4602 public key of the responder was not added to the computation
4603 even though it is mandatory. Affected file lib/silcske/silcske.c.
4604 This unfortunately causes incompatibilities with older
4605 clients and servers.
4607 * Added WIN32 specific network init and uninit functions:
4608 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4609 the Winsock2. Affected file lib/silcutil/silcnet.h and
4610 lib/silcutil/win32/silcwin32net.c.
4612 * Set the socket always to nonblocking mode on WIN32 after
4613 reading data or writing data. Affected file is
4614 lib/silcutil/win32/silcwin32sockconn.c.
4616 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4618 * Fixed various compilation problems under WIN32. Affected
4619 files lib/silcutil/win32/silcwin32thread.c and
4620 lib/silcutil/win32/silcwin32schedule.c.
4622 * Removed all _internal.h #includes from public header
4623 files. Internal headers must never be included from
4626 Removed also the lib/silcske/payload_internal.h file.
4628 * All include files that may be needed (public and some others
4629 included by the public headers) by application developers are
4630 now copied to the ./includes directory. It does not copy any
4631 internal headers. Affected file Makefile.defines.pre and all
4632 Makefile.am's under lib/ and subdirs.
4634 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4636 * Do not change the ~/.silc directory's permissions automatically.
4637 Affected file irssi/src/silc/core/clientutil.c.
4639 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4641 * Do not cancel the protocol in silc_server_close_connection
4642 it might cause recursion. Now cancelled in the function
4643 silc_server_free_sock_user_data. Affected file silcd/server.c.
4645 * Fixed the silc_server_remove_clients_by_server to regenerate
4646 the channel keys correctly finally. Added also new function
4647 silc_server_remove_clients_channels to actually do it.
4648 Affected file silcd/server.c.
4650 * Fixed the silc_server_new_channel to not crash by giving
4651 wrong router to the new channel. Affected file is
4652 silcd/packet_receive.c.
4654 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4656 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4657 which is given as argument to the silc_client_alloc now.
4658 It can be used to configure the client and set various parameters
4659 that affect the function of the client.
4661 * The USERS command in server did not check whether the channel
4662 is private or secret. Affected file silcd/command.c.
4664 * Added new argument to the USERS command in protocol specification.
4665 The USERS command now can take the channel name as argument
4666 as well. Added support for this in client and server and
4667 updated the protocol specs.
4669 * Completed the GETKEY command in client. It can be now used
4670 to fetch also servers public key not only some clients.
4671 Affected files lib/silcclient/command[_reply].c.
4673 * Added silc_client_get_server to return server entry by the
4674 server name. Affected files lib/silcclient/silcapi.h and
4677 * Redefined the IDENTIFY command in protocol specification to be
4678 more generic. It now can be used to query information about
4679 any entity in the SILC Network, including clients, servers and
4680 channels. The query may be based either the entity's name
4681 or the ID. Added support for this in both client and server.
4683 Affected files silcd/command.c and lib/silcclient/command.c
4684 and command_reply.c.
4686 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4687 the _from_client and _from_server functions. Affected file
4690 * Added silc_client_get_channel_by_id_resolve to the file
4691 lib/silcclient/silcapi.h to resolve channel information by
4692 its ID. Added also silc_client_get_channel_by_id that
4693 does not resolve it from the server.
4695 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4697 * Added SilcServerEntry context into the client library
4698 to represent one server. The INFO command now allocates
4699 these to save the resolved server info. For now on the
4700 client library will also keep information about servers,
4701 connected and resolved with INFO.
4703 The INFO command now allocates the SilcServerEntry context
4704 and saves the server info there. The COMMAND_REPLY in
4705 the INFO now returns the parameters to application in
4706 same order as defined in the protocol specification.
4708 The entries are cached in the client->server_cache.
4710 * The INFO command is now issued after received the Client ID
4711 from the server. Affected file lib/silcclient/client.c.
4713 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4714 to the application as the mode changer might be server.
4715 It is guaranteed that NULL is not returned anymore to the
4716 application. Affected file lib/silcclient/client_notify.c.
4718 The ID Type is now also passed to the application so that
4719 it can check whether the returned entry is SilcClientEntry
4722 Added new function silc_client_get_server_by_id to return
4723 the server entry by ID. Affected files are the
4724 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4726 * Do not create the channel in the Irssi SILC Client when issuing
4727 the JOIN command but when received the sucessful JOIN command
4728 reply. Otherwise the channel might get created even though we
4729 could not join it. The Affected file is
4730 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4732 * Fixed a channel joining bug in router. The router must also
4733 check the channel modes, invite and ban lists etc. when serving
4734 the JOIN command sent by normal server. Affected file is
4735 silcd/command.c. The router now resolves the client's
4736 information from the server who sent the JOIN command if it
4737 does not know it, and processes the JOIN command only after
4740 * Changed the SilcCommandCb to take new argument; void *context2.
4741 Affected file lib/silccore/silccommand.h
4743 The second argument in the command callbacks in the server now
4744 includes the SilcServerCommandReplyContext if the command was
4745 called as pending command callback from the command reply.
4746 Otherwise it is NULL. When called as pending the status of the
4747 command reply will be checked and if it was erronous the
4748 error will be sent to the original sender of the command.
4749 This way the client always receives the error messages even
4750 though the server was actually the one who received the error
4751 when it resent the command to router, for example. Affected
4752 files silcd/command[_reply].[ch].
4754 * Fixed sending WHOWAS command's error message to client if
4755 the requested client could not be found. It was missing.
4758 * Changed the CMODE and CUMODE commands reply arguments in the
4759 protocol specification. The Channel ID is now sent in both
4760 of the commands to identify the channel. Implemented this
4761 new feature to the client and server. Affected files
4762 lib/silcclient/command_reply.c and silcd/command.c.
4764 * Made better checks for invite and ban lists in the JOIN
4765 command in server. Affected file silcd/command.c.
4767 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4769 * The server now performs the incoming host IP/DNS lookup
4770 using the silc_socket_host_lookup and thus does not block
4771 the server anymore. Affected file silcd/server.c.
4773 * Completed the multi-thread support for SILC Scheduler in
4774 the lib/silcutil/silcschedule.c.
4776 * Fixed the configure.in.pre to detect the pthread correctly
4779 * Fixed a deadlock in silc_task_queue_wakeup in the file
4780 lib/silcutil/silctask.c.
4782 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4784 * Added new function silc_schedule_wakeup that is used in
4785 multi-threaded environment to wakeup the main thread's
4786 schduler. It needs to be used when a thread adds a new task
4787 or removes a task from task queues. After waking up, the
4788 scheduler will detect the task queue changes. If threads
4789 support is not compiled in this function has no effect.
4790 Implemented the wakeup mechanism to both Unix and WIN32
4791 systems. Affected files are lib/silcutil/silcschedule.[ch],
4792 lib/silcutil/unix/silcunixschedule.c and the
4793 lib/silcutil/win32/silcwin32schedule.c.
4795 * Added new function silc_task_queue_wakeup to wakeup the
4796 scheduler by the specified task queue. Affected file
4797 lib/silcutil/silctask.[ch].
4799 * The silc_socket_host_lookup_start now wakes up the scheduler
4800 after adding the timeout task. Affected file is
4801 lib/silcutil/silcsockconn.c.
4803 * The silc_socket_host_lookup is synchronous now if the threads
4804 support is not compiled in. However, the callback is still
4805 called asyncronously through the scheduler, anyway. Affected
4806 file lib/silcutil/silcsockconn.c.
4808 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4810 * Added new function silc_socket_host_lookup to perform
4811 asynchronous IP and FQDN lookups for the socket connection.
4812 Affected files lib/silcutil/silcsockconn.[ch].
4814 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4816 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4817 that may or may not compile the mutex support in.
4819 Changed the silc_mutex_alloc interface. It allocates the
4820 mutex now to the sent pointer and returns TRUE or FALSE.
4822 Affected file lib/silcutil/silcmutex.h.
4824 * Wrote the SILC Task Queue interface to support multi-threads.
4825 Affected file lib/silcutil/silctask.[ch].
4827 * Wrote the SILC Scheduler to support multi-threads. Affected
4828 file lib/silcutil/silcschedule.c.
4830 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4832 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4833 in lib/silcutil/win32/.
4835 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4837 * Defined SILC Mutex API and SILC Thread API and implemented
4838 them for Unix. Affected files are
4839 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4840 lib/silcutil/unix/silcunixmutex.c and
4841 lib/silcutil/unix/silcunixthread.c.
4843 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4845 * Fixed the silc_server_remove_clients_by_server's channel
4846 key re-generation. The hash table handling was incorrect
4847 and would not work with many channels. Affected file is
4850 * Fixed some memory leaks around the server code.
4852 * Rewrote the silc_server_get_users_on_channel to support IPv6
4853 based Client ID's. Affected file silcd/server.c.
4855 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4856 specification. However, a separate document must be written
4857 to define the detailed signing procedure and the payload
4858 associated with the flag. Defined the flag to the
4859 lib/silccore/silcchannel.h as well.
4861 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4863 * Changed the dynamic tables to static size tables in the
4864 lib/silccrypt/silchmac.c.
4866 * Removed GCC dependencies from the code. A patch by cras.
4868 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4870 * Do not show the error "Error receiving packet bla bla"
4871 in server if it really was not an error (-2 means that reading
4872 is pending). Affected file silcd/server.c.
4874 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4876 * Fixed a possible crash in silc_server_remove_clients_by_server
4877 in silcd/server.c. Fixed there also some memory leaks.
4879 * Fixed the silc_idlist_replace_client_id. It could replace
4880 wrong key in the hash table. Affected file silcd/idlist.c.
4882 * Do not check whether there are global users on the channel
4883 if the channel->global_users is FALSE. Affected functions
4884 silc_server_remove_from_one_channel and
4885 silc_server_remove_from_channels in silcd/server.c. Also,
4886 do not check if the removed client is local as we can be
4887 sure that global client was not removed from the channel
4888 and checking for global users is not needed.
4890 * The silc_server_remove_clients_by_server now re-generates
4891 the channel keys correctly for those channels that had
4892 clients removed from them. Affected file silcd/server.c.
4894 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4896 * Found the reason of random crashes in the server. We weren't
4897 ignoring the SIGPIPE signal (which can be sent in write())
4898 and it crashed the server. Affected file silcd/silcd.c.
4900 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4902 * Assure that sock->user_data is not NULL in the function
4903 silc_server_packet_send in silcd/packet_send.c.
4905 * Disconnect the remote connection if it could not be added
4906 to any ID lists in the server. The affected file is
4909 * Check in silc_server_packet_send[_real/dest] that the
4910 socket is not disconnecting and ignore the data if it is.
4911 Affected file silcd/packet_send.c.
4913 * Define inline to __inline on native WIN32 compilation.
4914 Affected file includes/silcwin32.h.
4916 * Added some explicit type casts for inline code since MSVC
4917 require them. Affected files lib/silcutil/silcbuffer.h,
4918 lib/trq/silcdlist.h and lib/trq/silclist.h.
4920 * Print warning in log files from now on if the packet
4921 decryption fails. Affected file silcd/server.c.
4923 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4925 * Changed the `say' client operation's interface to accept
4926 new `type' argument to indicate the type of the message sent
4927 by the library. The application may filter the library's
4928 messages according the type. The affected file is the
4929 lib/silcclient/silcapi.h.
4931 * Added two new functions to lib/silcclient/silcapi.h:
4932 silc_client_del_client and silc_client_del_client_by_id.
4933 Affected file lib/silcclient/idlist.c.
4935 * Moved the clientincludes.h from includes/ to silc/ and
4936 serverincludes.h from includes/ to silcd/.
4938 * The modes for the CMODE and CUMODE are now passed as
4939 uint32 for application with COMMAND_REPLY. The affected
4940 file is lib/silcclient/command_reply.c.
4942 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4944 * /WHOIS without arguments shows client's own information.
4945 Affected file lib/silcclient/command.c.
4947 * Changed PING to not accept any arguments. The specs
4948 says that client can ping only the connected server so
4949 requiring an argument is not needed. Affected file is
4950 lib/silcclient/command.c.
4952 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4954 * Fixed a fatal bug in private message sending and reception
4955 encryption and decryption when using private message keys.
4956 The implementation was incorrect and did not follow the
4957 specification. It causd that some of the message were
4958 lost since it did not use the sending and receiving keys
4959 as the protocol suggests. This has been fixed and will cause
4960 incompatibilities with older clients when sending private
4961 message encrypted with private message keys. Affected files
4962 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4963 and various other in Irssi SILC Client.
4965 Added `responder' boolean argument to the functions
4966 silc_client_add_private_message_key[_ske] to indicate when
4967 the key is added as responder or initiator of the key
4970 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4972 * Removed the silc_ske_check_version function and created
4973 a SilcSKECheckVersion callback. Added also a function
4974 silc_ske_set_callbacks that is now used to set all SKE
4975 callbacks. The callback functions are not given to
4976 the SKE functions anymore, but this function is used to
4979 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4981 * Added `silc_version' argument to the silc_client_alloc
4982 to define the version of the application for the library.
4983 The library will use the version string to compare it
4984 against the remote host's (usually a server) version
4985 string. Affected file lib/silcclient/silcapi.h
4987 * Added the KE protocol context to Key Agreement context
4988 in client library so that we can abort the SKE if it
4989 is in process when we get timeout. Affected file is
4990 lib/silcclient/client_keyagr.c.
4992 * Do not resolve the client ID forever if it returns in the
4993 first time that such client does not exist. This was done
4994 for example with private message. Affected file is
4995 lib/silcclient/client_prvmsg.c.
4997 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4999 * Do not add regex.h for WIN32. The affected file
5000 includes/silcincludes.h.
5002 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5003 not work yet 100%. It generates the DLL's automatically
5004 when compiling with --with-win32 under cygwin.
5006 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5008 * lib/contrib/regex.c is not compiled on WIN32.
5010 * Added silc_net_get_socket_opt function to the
5011 lib/silcutil/silcnet.h.
5013 * Added includes/silcwin32.h for WIN32 specific includes
5016 * Do not use ptime structure or any of the posix process
5017 functions on WIN32 in lib/silccrypt/silrng.c.
5019 * Added silc_gettimeofday to provide generic function
5020 for struct timeval on all platforms. Added the function
5021 to lib/silcutil/silcutil.h.
5023 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5025 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5026 library as they clearly belong there. As a plus side we
5027 can make the actual socket connection routines platform
5030 Added also new generic function silc_socket_read and
5031 silc_socket_write (that used to be silc_packet_[read/write].
5032 The implementation of these are platform specific.
5034 * Added WIN32 specific routines of silc_socket_[read/write]
5035 to lib/silcutil/win32/silcwin32sockconn.c.
5037 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5039 * Added preliminary support for native WIN32 compilation under
5040 cygwin (using the -mno-cygwin option for GCC) to the
5041 ./configure.in.pre. The --with-win32 now prepares the
5042 compilation for native WIN32.
5044 * Rewrote the SILC Scheduler interface in the file
5045 lib/silcutil/silcschedule.h. The scheduler is now context
5046 based and does not have anymore any global static scheduler.
5047 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5048 and created lib/silcutil/win32 directory for WIN32 based
5051 * Added Unix specific network routines to the
5052 lib/silcutil/unix/silcunixnet.c and the old
5053 lib/silcutil/silcnet.c includes now only generic routines.
5055 Added WIN32 specific network routines to the
5056 lib/silcutil/win32/silcwin32net.c.
5058 * Added Unix specific utility functions from the
5059 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5061 * Added WIN32 SILC Scheduler to the file
5062 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5065 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5067 * Do not handle JOIN notify in the server if the target client
5068 is not registered (idata->registered == FALSE). The affected
5069 file is silcd/packet_receive.c.
5071 * Update the nickrec->founder in event_cumode in the Irssi SILC
5072 client. Affected file irssi/src/silc/core/silc-channels.c.
5074 * Fixed the CUMODE_CHANGE notify handling in the server when
5075 server and router are announcing their clients on channels.
5076 Now the mode changes are saved and notified correctly. The
5077 affected file is /silcd/packet_receive.c.
5079 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5080 They really did not replace the cache entry in the ID Cache.
5081 Now they do that. Affected file silcd/idlist.c.
5083 * Fixed the KICK notify handling in the Irssi SILC client to
5084 update the channel records so that the kicked client does not
5085 appear to be on the channel. The affected file is
5086 irssi/src/silc/core/silc-channels.c.
5088 * Always update the conn->current_channel when executing command
5089 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5091 * Fixed the KILL notify handling in Irssi SILC client to remove
5092 the killed client on all channels.
5094 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Fixed the silc_parse_command_line to remove extra spaces
5097 from the start and end of the arguments. Affected file is
5098 lib/silcutil/silcutil.c.
5100 * Cancel and free any active protocol in the function
5101 silc_server_close_connection. Affected file silcd/server.c.
5103 * Cancel and free any active protocol in the function
5104 silc_client_close_connction. Affected file is
5105 lib/silcclient/client.c.
5107 * Do not execute the KILL command for clients that are in
5108 history (ie. they are not in the network). Affected file is
5111 * Fixed KILL notify handling, client does not crash anymore.
5112 Affected file irssi/src/silc/core/silc-channels.c.
5114 * Reduced the default packet buffer size from 2048 to 1024 in
5115 lib/silccore/silcpacket.c.
5117 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5118 counter to the SKE context that is incresed when the SKE library
5119 performs async operation outside the library. If the outside
5120 process frees the SKE context and FREED status will be set
5121 and the library will detect after the sync operation that the
5122 libary is freed. The affected files are
5123 lib/silcske/silcske[_status].[ch].
5125 * Resolve the client entry information in the function
5126 silc_client_channel_message to assure that NULL pointer is not
5127 passed as client entry to the application. */
5129 * Fixed the task timeout calculation to assure that there is
5130 never negative timeouts. The affected file is
5131 lib/silcutil/silcschedule.c.
5133 * Fixed the channel user mode notification sending in server.
5134 It was sent point-to-point to the router (or to server by router)
5135 but it needs to be destined to a channel. The routines now
5136 supports sending the channel user mode notifys to the channels
5137 when announcing clients and channels. Affected files are
5138 silcd/server.c and silcd/packet_receive.c.
5140 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5141 It did not actually replace the old channel entry in the cache.
5142 Affected file lib/silcclient/client_notify.c.
5144 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Fixed a possible crash in silc_packet_send_prepare. It now
5147 assures always that there is enough space in the buffer and
5148 at the tail area of the buffer (for MAC).
5150 Fixed the inbound buffer reallocation in silc_packet_read.
5151 It was old code and did not handle the reallocation correctly.
5154 The affected file is lib/silccore/silcpacket.c.
5156 * Fixed buffer overflow in silc_parse_nickname in the file
5157 lib/silcutil/silcutil.c.
5159 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * make install generates new server keys only if there is not
5164 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5167 Added check that if the NOREPLY is set then we will not send
5168 the away message. This avoids infinite loop of away messages
5169 if both clients are away. The affected file is
5170 lib/silcclient/client_prvmsg.c.
5172 * Fixed client crash if /NICK was given without arguments.
5173 Affected file lib/silcclient/command.c.
5175 * Server does not send the invite list in INVITE command back
5176 to the client if the list was not altered. Added this notion
5177 to the protocol spec as well. Affected file silcd/command.c.
5179 Fixed possible crash in INVITE command by checking the
5180 value of silc_server_get_client_route command.
5182 * Fixed the INVITE notify type handling. The arguments are now
5183 taken in correct order and client does not crash. The affected
5184 file is irssi/src/silc/core/silc-channels.c.
5186 Removed the "Inviting xxx to channel" message from the
5187 client library away and let the application handle it.
5188 Affected file lib/silcclient/command.c. Added that message
5189 to Irssi SILC client's message formats.
5191 * Fixed CMODE command crash in client. It now checks the
5192 amount of arguments correctly and does not crash. The affected
5193 file is lib/silcclient/command.c.
5195 * Do not create new channel automatically in silc_channels_join
5196 but check whether the channel by that name already exists.
5197 Affected file irssi/silc/core/silc-channels.c.
5199 * Do not send the SERVER_SIGNOFF to router if the disconnected
5200 entity was the router. Affected file silcd/server.c.
5202 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5203 SILC client as it was missing from there.
5205 Added the handling of the KICK notify to the Irssi SILC client
5206 as it was missing. Added "you have been kicked" message to
5207 Irssi SILC client's message modules formats.
5209 Added the handing of the KILL notify to the Irssi SILC client
5210 as it was missing. Added the kill message module formats
5213 The affected file is irssi/src/silc/core/silc-channels.c.
5215 * The router did not save the channel mode the server announced.
5216 Affected file silcd/packet_receive.c.
5218 * Fixed a possible crash in INFO command in server. If the
5219 server did not provide the server info it crashed. Affected
5220 file silcd/command.c.
5222 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Fixed the GETKEY command in the server to check also the
5225 global list. Otherwise the GETKEY would not work correctly
5226 in normal SILC server. Affected file silcd/command.c.
5228 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Fixed GETKEY crash, it crashed if the command did not succseed.
5232 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5235 is now real and not just an macro interface to GMP.
5237 Removed the entire GMP from the source tree and imported new
5238 NSS MPI library instead. Reason for removing GMP is that it is
5239 extremely large and compiles extremely slow. The NSS MPI
5240 is only a few files and compiles in less than 10 seconds.
5241 The speed is also about the same as GMP. The MPI is imported
5242 to lib/silcmath/mpi.
5244 If the system has GMP installed we will still use the GMP.
5245 If it is not then the NSS MPI will be compiled.
5247 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Merged a long nickname (127 characters long) crash bugfix from
5250 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5252 * Merged a freed memory reference bugfix from Irssi CVS tree.
5253 Affected file irssi/src/core/commands.c.
5255 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Added the server's public key sving and verification to the
5258 server when performing the SKE. This was missing and the
5259 remote server's (or router's) public key was accepted without
5260 checking whether we have it previously or trust it at all.
5261 Affected file silcd/protocol.c.
5263 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Check in the silc_server_timeout_remote if protocol is active
5266 and make sure that the protocol's final callback is called so
5267 that all memory if freed. Affected file silcd/server.c.
5269 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * silc_server_whois_send_reply crashed the server if the nickname
5272 was 127 characters long. Affected file silcd/command.c.
5274 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Added sanity check to the silc_server_new_client. If the hostname
5277 is provided inside username then check that the provided hostname
5278 really is the same as the resolved one. If the hostname was not
5279 resolved then check it from the public key. Affected file is
5280 silcd/packet_receive.c.
5282 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5283 if the server disconnected us and the connection is not valid
5284 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5286 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5287 the library to the lib/silcutil/silcutil.[ch].
5289 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Close log file after open. Affected file
5292 lib/silcutil/silclog.c.
5294 * Check whether sock == NULL in silc_client_send_packet and return
5295 if it is. Affected file lib/silcclient/silcclient.c.
5297 * Check rec->entry == NULL in the Irssi SILC Client before
5298 sending the channel message. Affecte file is
5299 irssi/src/silc/core/silc-servers.c.
5301 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Merged a splitted window bugfix from Irssi CVS tree. The
5304 affected file is irssi/src/fe-text/textbuffer-view.c.
5306 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5307 It did not print nickname.
5309 * Improved the distributions system a bit.
5311 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5314 irssi/src/fe-text/gui-window.c.
5316 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5317 to in-active server. The affected file is
5318 irssi/src/silc/core/client_ops.c.
5320 * Resolve the client in USERS command reply if the entry does
5321 not have username resolved. The affected file is
5322 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5323 command to WHOIS command to really resolve stuff. The USERS
5324 is not used any more in any critical section so WHOIS can
5325 be used even though it might be slower than IDENTIFY.
5327 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5330 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Changed the protocol API a bit more consistent in the
5333 lib/silccore/silcprotocol.[ch].
5335 * Changed the following headers to ROBODoc format:
5337 lib/silccore/silcpayload.h
5338 lib/silccore/silcprotocol.h
5339 lib/silccore/silcsockconn.h
5341 All core library headers are now formatted.
5343 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Fixed a bug in Irssi SILC client; do not show that you are
5346 server/router operator if you really are not. Affected file is
5347 irssi/src/silc/core/client_ops.c.
5349 * Renamed silc_command_free_payload to silc_command_payload_free.
5350 Affected file lib/silccore/silccommand.h
5352 * Added silcmath.h to include the prototoypes of various routines
5353 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5356 * Changed the following headers to ROBODoc format:
5358 lib/silccore/silcchannel.h
5359 lib/silccore/silccommand.h
5360 lib/silccore/silcid.h
5361 lib/silccore/silcidcache.h
5362 lib/silccore/silcmode.h
5363 lib/silccore/silcnotify.h
5364 lib/silccore/silcpacket.h
5365 lib/silcmath/silcmath.h
5367 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Added checking to the server code not to start the server if
5370 ciphers and stuff are not configured properly. Affected files
5371 silcd/serverconfig.[h] and silcd/server.c.
5373 * Changed the layout of the header files of the public interfaces
5374 in the SILC libraries. The new layout supports ROBODoc
5375 documentation tool (and some others) so that it is easy to create
5376 a library reference manual. All the other headers and source
5377 code must still follow the CodingStyle document. Also source
5378 code must not include these ROBODoc stuffs, only the headers.
5379 Furthermore, all public interface headers must now be named
5380 by using `silc' prefix, example: silcapi.h, silccipher.h.
5381 Some files were renamed due to this. All the other headers
5382 must not be used as public interfaces. I will update the
5383 CodingStyle document later. Changed following headers, so far:
5385 lib/silcclient/silcapi.h
5386 lib/silccore/silcauth.h
5387 lib/silccore/silcprivate.h
5388 lib/silccrypt/silcdh.h
5390 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Removed silc_client_packet_send_flush from the client library
5395 as it is not needed. Affected file lib/silcclient/client.[ch].
5397 * Added printing of message of unresolved authentication method
5398 to the Irssi SILC client. Added it to the module formats.
5399 Removed the same message from the client library.
5401 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Added new distribution feature, DISTLABEL. Every distribution
5404 can define own preprocessor label that can be used in the
5405 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5406 file distributions, acconfig.h.pre and prepare.
5408 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Added Makefile.defines_int to include the actual definitions
5411 for Makefile.defines.in. Tested the new distribution system,
5412 created distributions and tested installation.
5414 * Added AWAY message printing to the Irssi SILC client. Added
5415 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5417 * Added SCONNECT command to call the SILC's CONNECT command.
5418 Cannot use CONNECT directly since Irssi uses that internally.
5419 Affected file irssi/src/silc/core/silc-servers.c.
5421 Added ACTION local command. It is same as ME command but takes
5422 the channel as mandatory argument.
5424 Rewrote some of the Irssi's help files to suite for SILC
5427 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Added Makefile.defines[.in] that should for now on be included
5430 in all Makefile.am file in the source tree. That file includes
5431 all common compilation definitions for SILC source tree.
5433 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Minor changes to the ./prepare script to change the package
5436 name according the distribution name to the configure.in.
5438 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Created new distribution system. Added file `distributions'
5441 that defines all the distributions that can be created out of
5442 the SILC source tree. The ./prepare script now reads that
5443 file to determine how to prepare the distributions. The
5444 first argument to the ./prepare is the name of the distribution
5445 and second is the version of the distribution. If given
5446 without arguments it creates the default (toolkit) distribution
5447 with the default version (defined in ./prepare).
5449 All Makefile.am files that are subject to the distributions
5450 are now named as Makefile.am.pre. These are ./Makefile.am
5451 and lib/Makefile.am. Others may be changed later.
5453 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Added invite list, ban list, some key management and connection
5456 error message printing to module formats in the Irssi SILC client.
5458 * Added new silc_client_set_away_message to set the away message
5459 that is back to the person who sent private message. The
5460 affected file lib/silcclient/silcapi.h and the
5461 lib/silcclient/client_prvmsg.c.
5463 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Fixed the private message sending in the Irssi SILC client,
5466 added local command KEY to the Irssi SILC client.
5468 Added key management and key agreement message formats to the
5469 irssi/src/fe-common/silc/module-formats.[ch].
5471 Added USERS (alias WHO) printing, server/router operator
5472 indication and LIST command printing to the module formats.
5474 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Fixed channel joining notify handling, cumode notify handling
5477 from Irssi SILC client.
5479 * Added SILC specific module-formats to the Irssi SILC client so
5480 that SILC specific message hilighting, colors etc is possible.
5481 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5483 Added channel mode, channel user mode, actions, notices,
5484 whois and whowas printing to the the module-formats.c.
5486 * Fixed a bug in channel deletion in the server. The channel
5487 is not left to the cache even if the channel founder auth mode
5488 is set when there are no users anymore on the channel. Affected
5489 file silcd/server.c.
5491 * The silc_net_localhost now resolves the entire hostname including
5492 the domain name. Affected file lib/silcutil/silcnet.c.
5494 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Changed the ask_passphrase client operation to be ascynchronous.
5497 It has now a completion callback and a context that the
5498 application must call after it has got the passphrase from
5499 the user. Affected files lib/silcclient/silcapi.h,
5500 lib/silcclient/protocol.c, lib/silcclient/command.c and
5503 Added SilcAskPassphrase callback that the application calls
5504 to deliver the passphrase to the library.
5506 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5507 The public key verification and especially a certificate
5508 verification is asynchronous procedure.
5510 Added new SILC_SKE_STATUS_PENDING status to indicate the
5511 request is pending and a callback will be called to finalize
5514 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5515 indicate that remote end did not send its public key (or
5516 certificate), even though we require it. Added check for this
5517 condition in the SKE. This was a security bug, now fixed.
5519 Defined new SilcSKEVerifyCbCompletion callback that is called
5520 when the verification process is completed.
5522 The affected files lib/silcske/silcske_status.h and
5523 lib/silcske/silcske.[ch].
5525 * Changed the verify_public_key client operation to be async
5526 as well. Defined SilcVerifyPublicKey callback that is used to
5527 indicate the success of the public key verification process.
5529 Changed the server and client to use the new async client
5532 * Changed the Irssi SILC client's internal scheduler to be called
5533 twice as many times as it used to be. As a result the client
5534 should be a bit faster now. Affected file is
5535 irssi/src/silc/core/silc-core.c.
5537 * Added support to Irssi SILC client of asynchronous public key
5538 verification and passphrase inquiry. Affected file is
5539 irssi/src/silc/core/silc-core.c.
5541 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Do not say "You have left channel %s" in client library.
5544 Moved it to the application. Affected files are
5545 lib/silcclient/command.c and silc/client_ops.c.
5547 * Fixed silc_client_get_clients. Command context was not
5548 duplicated and was freed memory in the callback. Affected
5549 file lib/silcclient/idlist.c.
5551 * Do not say "you are now talking..." on JOIN command in the
5552 client library. The appliation must handle it.
5554 * Do not say ".. changed topic to" in command reply in the
5555 client libary. The application must handle it.
5557 * Fixed TOPIC command sending in the client library.
5559 * Fixed a memory leak in silc_client_command_free in the file
5560 lib/silcclient/command.c.
5562 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Imported a modified version of Irssi client to the source tree.
5565 The Irssi will be used to create a new client called
5566 Irssi SILC. Imported to irssi/.
5568 Added silc_core_init_finish function to the Irssi. Affected
5569 file irssi/configure.in.
5571 A lot changes in the Makefile.ams around the irssi tree.
5573 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Do not rehash if the new size is same as the old size of the
5576 hash table, in the silc_hash_table_rehash*. The affected file
5577 lib/silcutil/silchashtable.c.
5579 * Replaced hash_table_del_by_context calls from the server
5580 (when channel->user_list and client->channels) to the
5581 hash_table_del as it is sufficient and faster.
5583 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Added silc_hash_table_list, silc_hash_table_get and the
5586 SilcHashTableList structure to provide an alternative way to
5587 traverse the hash table. The affected files are
5588 lib/silcutil/silchashtable.[ch].
5590 * Changed the server's idlist routines to use the hash table
5591 routines to optimize the code.
5593 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Replaced the client entry's `channel' list and channel entry's
5596 `user_list' list to hash tables for optimized lookup. Changed
5597 the code to use the hash table interface around the code.
5598 Affected file lib/silcd/idlist.[ch].
5600 * Added `auto_rehash' boolean argument to the function
5601 silc_hash_table_alloc to indicate whether the hash table should
5602 auto-rehash when it thinks is appropriate time. It will
5603 increase the hash table size if the there is twice as much
5604 entries in the table than the size of the table, and will
5605 decrease the size if there are twice as less entries than
5606 the size of the table.
5608 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5612 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * silc_idcache_purge_by_context deletes the entry now by context
5615 as it is supposed to do. Affected file lib/silccore/idcache.c.
5617 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5618 client is not anymore valid (WHOWAS givens the info) and not
5619 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5621 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Removed the `data' and `data_len' arguments from the ID Cache
5624 interfaces and added `name' argument. ID Cache does not handle
5625 anymore the binary data only a names associated with given ID.
5627 * When hashing a Client ID with silc_hash_id the entire ID is
5628 not hashed anymore, instead only the hash of the Client ID is
5629 hashed. This way we can access the Client ID from the cache
5630 with Client ID but with the hash of the ID (which is a hash of
5631 the nickname) as well without any difference in performance.
5633 Added also silc_idcache_find_by_id_one_ext to do one on one
5634 searching when we have the actual ID. Added also function
5635 silc_hash_client_id_compare. The affected files are
5636 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5638 * When hashing the name associated with a ID it is always done
5639 in lowercase. This way we can access the cache without worrying
5640 about case-sensitivity, even though, for example nicknames are
5643 * Fixed a bug in server with channel message sending. It put
5644 wrong ID type as destination ID. The affected file
5645 silcd/packet_send.c.
5647 * silc_idcache_del_by_context now deletes from all hash tables
5648 by context. Affected file lib/silccore/idcache.c.
5650 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Changed the client library to use the new ID Cache interface.
5653 Changes around the source tree.
5655 * Added silc_hash_table_rehash_ext to rehash with specific
5656 hash function. Affected file lib/silcutil/silchashtable.[ch].
5658 * Added silc_hash_string_compare to compare two strings in the
5659 hash table. Affected file lib/silcutil/silcutil.[ch].
5661 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Added new function silc_idcache_del_by_context into the
5664 lib/silccore/idcache.[ch].
5666 * Changed the server's ID list routines to use the new ID Cache
5667 interface. Changes around the source tree.
5669 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Added silc_hash_table_del[_by_context]_ext functions in to the
5672 lib/silcutil/silchashtable.[ch].
5674 Removed silc_hash_table_find_all* routines and added new
5675 silc_hash_table_find_foreach to replace them.
5677 Added silc_hash_table_replace_ext function as extended
5678 replacing function. Separated the simple hash table interface
5679 from the extended hash table interface in the file
5680 lib/silcutil/silchashtable.h.
5682 * Fixed minor bugs and changed it to use some of the new
5683 hash table functions in lib/silccore/idcache.c
5685 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added new function silc_hash_table_find_all to return all keys
5688 in the hash table by the specified key. As the hash table is
5689 collision resistant it also makes it possible to have several
5690 duplicate keys in the hash table. This function may be used to
5691 find all of the keys from the hash.
5693 Added user_context arguments to the SilcHashFunction,
5694 SilcHashCompare and SilcHashDestructor to deliver user specified
5697 Added new fuctions silc_hash_table_find[_all]_ext to do
5698 extended lookup with specified hash and compare functions and
5699 specified user contexts.
5701 Added new function silc_hash_table_add_ext to add the key
5702 with specified hash function and user context.
5704 Added new function silc_hash_table_foreach to traverse all
5705 entrys in the hash table. Added SilcHashForeach callback
5708 Added new function silc_hash_table_del_by_context to delete
5709 the entry only if the context associated with the key matches.
5711 Affected files are lib/silcutil/silchashtable.[ch].
5713 * Removed silc_hash_[server/client/channel]_id and added just
5714 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5715 silc_hash_id_compare to compare two ID's using as the hash table
5716 comparison function. Added also silc_hash_data to hash
5717 binary data and silc_hash_data_compare to compare it.
5719 * Removed silc_idlist_find_client_by_hash as it is not needed
5720 anymore. Affected file silcd/idlist.[ch].
5722 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5723 to use internally the SilcHashTable. The new ID Cache is a lot
5724 faster than the old one. Some of the ID Cache interface was also
5725 rewritten and obsolete and stupid functions were removed.
5727 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Added entry_count field to the SilcHashTable to keep the number
5730 of the entries in the table. Implemented the function
5731 silc_hash_table_rehash. Added new function
5732 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5734 Fixed a minor bug in silc_hash_table_free.
5736 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5737 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5738 into the lib/silcutil/silcutil.[ch].
5740 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Implemented a collision resistant hash table into the
5743 lib/silcutil/silchashtable[ch]. See the header and the source
5744 for the SilcHashTable API.
5746 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Merged dotconf version 1.0.2 into lib/dotconf.
5750 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * Do not compile anything in lib/silcsim/* if the SIM support
5753 is not enabled. The tree should now compile without problems
5756 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Compiled the SILC under cygwin. Compiled and tested briefly
5759 without problems. More tests needed. The SIMs didn't compile
5762 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5764 * Fixed possible crash in silc_get_username in the
5765 lib/silcutil/silcutil.c.
5767 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Fixed a va_arg in silc/client_ops.c.
5771 * Oops, RC5 routines were named AES and caused some problems
5772 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5774 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Added new SilcIDIP structure into the lib/silccore/id.h and
5777 replaced the old `ip' fields from all SILC ID's to that type.
5778 This is a step towards IPv6 support.
5780 The silc_id_get_len takes now the ID as an extra argument.
5781 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5782 both IPv4 and IPv6 based ID's.
5784 The affected files are lib/silccore/id.[ch] and other files
5785 around the tree using these routines.
5787 * Removed the ID length arguments in server from various
5788 silc_server_send_notify_* routines -> they are not needed
5791 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Fixed memory leak in silc_encode_pem_file in the file
5794 lib/silcutil/silcutil.c.
5796 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * Check minor version as well in the SKE. Affected files are
5799 silcd/protocol.c and lib/silcclient/protocol.c.
5801 * Added --identifier option to the server so that an identifier
5802 can be when creating the public key for the server. Affected
5803 file is silcd/silcd.c.
5805 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5806 lib/silccrypt/silcpkcs.c.
5808 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Register default ciphers and stuff when using -C option with
5811 the server. Affected file sildc/silcd.c.
5813 * Put back the servers public key filename format, it is better
5814 than the new one. For now, the client keys are saved with the
5815 new filename format. The affected file silc/client_ops.c.
5817 * Implemented the Cipher API for the rest of the ciphers that
5818 did not implement it or implemented it the wrong way.
5820 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Register default ciphers and stuff when using the -S option
5823 in the client. Affected file silc/silc.c. Same also when
5824 creating new key pair with -C option.
5826 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Fixed the silc_verify_public_key client operation function to
5829 save the public keys differently. The fingerprint is now
5830 used as filename and not the hostname. This way also the
5831 client keys are saved uniquely and not with hostnames. The
5832 affected file is silc/client_ops.c.
5834 * Trimmed the silc_hash_fingerprint function to remove extra
5835 whitespaces from the end of the fingerprint. The affected
5836 file is lib/silccrypt/silchash.c.
5840 * Added silc_cipher_register_default function to register all
5841 default ciphers. It can be used when configuration files
5842 does not exist and the application does not want any specific
5843 ciphers in any specific order.
5845 The SilcDList is now used as silc_cipher_list dynamically
5846 allocated cipher list. Removed the static list all together
5847 and now all ciphers must be allocated to the dynamic list.
5848 The silc_cipher_alloc routine was changed to check only the
5851 All silc_cipher_* routines that used to return int returns
5854 The affected files lib/silccrypt/silccrypt.[ch].
5856 * The same thing was done to silc_hash_* as for silc_cipher_*
5857 routines. Affected files lib/silccrypt/silchash.[ch].
5859 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5860 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5861 Added also silc_pkcs_[un]register[_default] functions.
5862 Removed the data_context from the PKCS API.
5864 * Added silc_hmac_register_default function to register default
5865 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5866 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5867 to unregister all hmacs at once.
5869 * Register the default ciphers, hash functions, PKCSs and HMACs
5870 if client's configuration file does not exist. The affected
5873 * The client did not load the hash functions from the SIM
5874 modules at all. Added support for this. Affected file is
5875 silc/clientconfig.c.
5877 * When decoding public key with silc_pkcs_public_key_decode, check
5878 the supported algorithm only if PKCS are registered. Affected
5879 file lib/silccrypt/silcpkcs.c. The same was done with the
5880 silc_pkcs_private_key_decode.
5882 * Fixed the SILC List routines to keep the list always in order.
5883 It used to change the list's order when traversing the list but
5884 not it preserves the order. Affected file lib/trq/silclist.h.
5886 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Added the client library to use the SilcSocketConnection's
5889 reference counter (by silc_socket_dup) to prevent the bug that
5890 the socket object may be freed underneath async operation.
5892 * The name resolv library checking fixes in the configure.in.pre.
5895 * Created new version of the protocol drafts for future
5896 development. The -03 drafts are the ones that will be changed
5897 in the trunk now and the -02 will remain as they are.
5899 * Send list of CUMODE notifys to the router when announcing
5900 the channel users to the router. Affected file silcd/server.c.
5901 If the router receiving channel founder CUMODE for a channel
5902 that already has channel founder it will send CUMODE notify
5903 to the sender to remove the channel founder rights from the
5904 announced client. Affected file silcd/packet_receive.c.
5906 * The CUMODE notify may now use Server ID as well as the entity
5907 who changes the mode. Updated protocool specs.
5909 * Updated INSTALL and README files.
5911 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * New web pages in the http://silc.pspt.fi. The pages was
5918 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Implemented the [DenyConnectin] config section in the server.
5921 Added silc_server_config_denied_conn to check whether incoming
5922 connection is denied. Affected file silcd/serverconfig.[ch].
5924 * Do not check the ports when checking the incoming configuration
5925 data if the port is 0, meaning any. Affected file is
5926 silcd/serverconfig.c.
5928 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Fixed buffer overflow in silc_string_compare in the file
5931 lib/silcutil/silcutil.c.
5933 * Fixed double free in silc_server_command_leave in the file
5936 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Fixed the version checking in the server. Affected file is
5941 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Fixed the configuration data fetching when accepting new
5944 connections in the server. Affected file silcd/server.c.
5946 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Added `sender_entry' argument to the function
5949 silc_server_packet_relay_to_channel so that we can check
5950 whether some destination actually belongs to the same route
5951 the sender belongs (ie, we must not resend the packet to the
5952 sender). Affected file silcd/packet_send.[ch].
5954 * Added `servername' field to the SilcClientEntry in the server
5955 to hold the name of the server where client is from. Affected
5956 file is silcd/idlist.h.
5958 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Moved the channel message encrypting in the router betwen
5961 router connections from silc_server_channel_message to the
5962 silc_server_packet_relay_to_channel since we want to check
5963 whether we have anybody channel before encrypting anything.
5964 Affected files silcd/packet_[receive/send].c.
5966 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Fixed the [AdminConnection] server config section to support
5969 multiple entries. Affected file silcd/serverconfig.c.
5971 * Added support into the server to check the validity of the
5972 incoming connection before executing any KE or authentication
5975 * The connection configuration is now saved to the KE and
5976 connection auth protocol contexts and not fetched anymore in
5977 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5979 * The local hosts listenning address and port is also resolved
5980 now when starting the server. We want to have the socket object
5981 to include the real address and port for the listener. Added
5982 new function silc_net_check_local_by_sock into the files
5983 lib/silcutil/silcnet.[ch].
5985 * Fixed a broadcast bug in server -> do not broadcast if we
5988 * Fixed a routing bug. Do not route broadcast packets ever.
5989 Broadcast packets must be processed always and not routed since
5990 they may be destined to some other host than yourself and thus
5991 would get routed without no good reason. Affected file is
5994 * Added function silc_server_config_is_primary_route to check
5995 whether primary router connection has been configured (a router
5996 configuration that we are initiating). If there is not, we
5997 will assume that there is only two routers in the SILC network
5998 and we will use the incoming router connection as our primary
5999 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6001 * Changed the order of the broadcasting. Broadcast _after_ the
6002 packet has been processed not before. Affected file is
6005 * Fixed a [ClientConnection] parsing bug. The port was never
6006 parsed correctly thus resulting to port 0. Affected file
6007 silcd/serverconfig.c.
6009 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6010 argument and did not set the broadcast packet flag. Affected
6011 file silcd/packet_send.c. Fixed same bug in the function
6012 silc_server_send_notify as well.
6014 * If we receive NEW_ID packet for our own ID in the server, ignore
6017 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Removed the nickname from the Private Message Payload.
6022 Updated the code and the protocol specs.
6024 * Updated protocol specs for submitting to the IETF.
6026 * Tweaked the Random Number Generator a bit. Affected file
6027 lib/silccrypt/silcrng.c. Exported a new function
6028 silc_rng_[global]_add_noise which can be used to add more
6031 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Do not parse packets with different timeout when protocol
6034 is active -> may cause problem with rekey. Affected file
6037 * When server receives signoff notify it must not create
6038 new channel key if the client is on any channels since the
6039 sender of the signoff notify will create it.
6041 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added printing of error messages during SKE protocol from the
6044 failure packet sent by server during SKE. Affected file
6047 * Removed the client's failure_callback handling with timeout
6048 and handle it immediately when received.
6050 * The SKE library returned wrong type in SUCCESS and FAILURE
6051 packets. They must be 32 bit MSB not 16 bit MSB.
6053 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Ok, rewrote the logic of the re-key and now it seems to work.
6056 I tested it on high traffic with frequent re-keys without
6057 problems. Added hmac_receive (and renamed hmac to hmac_send)
6058 in SilcClientConnection in lib/silcclient/client.h and
6059 in SilcIDListData in silcd/idlist.h. Also, removed the
6060 SilcPacketParserContext's cipher and hmac fields as they are
6061 not needed anymore and actually caused some problems when
6062 the ciphers and hmac's changed underneath the packet parser.
6064 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * If re-key protocol is active then process the incoming packets
6067 synchronously since we must assure that icoming packets encrypted
6068 with the old key is processed before the new keys is set to
6069 use. This is true other packets than for REKEY packets.
6070 Affected file silcd/server.c. The same was done to client library
6071 as well, affected file lib/silcclient/client.c.
6073 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Fixed bug in client and server to accept the force send if
6076 the packet is send from silc_[server/client]_packet_process
6077 function. Otherwise the packets are never delivered, oops.
6079 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6081 * Disable force sending of packets when REKEY protocol is active.
6082 We must assure that no packet is sent directly when rekey is
6083 performed. All packets must be sent through packet queue.
6084 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6085 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6086 function is silc_[server/client]_packet_send_real to check
6089 * Replaced the SIM paths from example config files to
6090 /usr/local/modules. Also, make install creates now
6091 /usr/local/silc/logs directory to hold all the SILC server
6094 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Made the configure.in.pre work on Solaris. Patch by salo.
6098 * Made all ciphers compatible with non-x86 machines. Defined
6099 CBC mode macros into lib/silccrypt/ciphers_def.h.
6101 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Fixed the make install.
6105 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * When MAC computation fails the silc_packet_decrypt returned 0
6108 even though it was supposed to return -1. Fixed this. The
6109 affected file is lib/silccore/silcpacket.c.
6111 * Do not replace the config files in /etc/silc (in make install)
6112 if they already exist. Affected file ./Makefile.am.
6114 * Do not send re-key packets immediately but through packet queue.
6115 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6117 * Changed silc_net_check_host_by_sock to return FALSE if the
6118 IP/DNS could not be resolved. Though, it returns the IP address
6119 now even if it could not resolve it (but returns also FALSE).
6120 Affected file lib/silcutil/silcnet.[ch].
6122 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Added silc_pkcs_decode_identifier to decode the public key's
6125 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6126 Added also silc_pkcs_free_identifier. Added also new context
6127 SilcPublicKeyIdentifier.
6129 * Added -S option to the silc client. It is used to dump the
6130 contents of the specified public key file.
6132 * Changed the PKCS api to return the public key length when
6133 setting the public key.
6135 * Fixed a fatal bug in the public and private key file loading.
6136 Affected file lib/silccrypt/silcpkcs.c.
6138 * Execute the packet parsing for client with zero (0) timeout
6139 if the protocol is active. Affected file silcd/server.c.
6141 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6143 * Made the key generation options to the silcd program. Added
6144 -C option, equivalent to client's option.
6146 * Added new [ServerKeys] config section to the server. It
6147 configures the server's public and private key.
6149 * Defined generic Public Key Payload into the protocol
6150 specification to send specific type of public keys and
6153 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6154 public key or certificate.
6156 * Implemented the GETKEY command to the server and to the
6157 client library and on user interface.
6159 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Made preliminary `make install' work.

6190 SilcClientConnection structure; not needed. Affected file is
6191 lib/silcclient/client.h.
6195 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Do not ask whether user wants to use the negotiated private key
6198 for private messages, just use it. Affected file is
6199 silc/local_command.c.
6201 * Added `send_enc_key' and `enc_key_len' fields to the
6202 SilcIDListData structure since they are needed in the re-key
6203 phase. Affected file is silcd/idlist.[ch].
6205 * Implemented the simple re-key protocol into the server.

6217 the PFS is to be performed in the re-key. Affected file is
6220 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6223 int64 of at least the xintXX size. If void * is less that 4
6224 bytes uint32 * will be used. Defined bool as boolean.
6226 * Changed _ALL_ unsigned long and unsigned int to uint32,
6227 unsgined short to uint16 in the source tree.
6229 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6230 not handle clients that has entry->data.registered == FALSE.
6231 They are not in the network anymore. Affected file is
6234 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Implemented the sending of the SERVER_SIGNOFF notify in the
6237 server. Affected file is silcd/server.c.
6239 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6240 Added also silc_notify_payload_encode_args into the

6243 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6244 Affected file silcd/packet_receive.c.
6246 * Implemented the SERVER_SIGNOFF notify handling in the client
6247 library. Affected file lib/silcclient/client_notify.c. Also,
6248 implemnted the printing of the SERVER_SIGNOFF info to the
6249 application. Affected file silc/client_ops.c.
6251 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6252 if the deleting was successful. Affected file silcd/idlist.[ch].
6254 * Added support for public key authentication in the connection
6255 authentication protocol in the client library. Affected file
6256 lib/silcclient/protocol.c.
6258 * Changed the server's silc_idlist_get_clients_by_* interface
6259 to support already allocated array so that new entries may be
6260 added to pre-allocated array. Affected file silcd/idlist.[ch].
6261 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6262 and command replies.
6264 * All command reply functions in the server now calls the
6265 pending command callback even if error occured. This way the
6266 error will be delivered to the client as well. Affected files
6267 silcd/command.c and silcd/command_reply.c.
6269 * Fixed INFO command to return local server's info if no server
6270 was provided. Affected file lib/silcclient/command.c.
6272 * Removed RESTART command for good. Updated the code and the

6279 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Moved the USERS printing from the library to the application.
6282 Affected files lib/silcclient/command.c and silc/client_ops.c.
6284 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Added channel key re-key support. The re-key is perfomed
6289 only by the router and is done once in an hour. Added `rekey'
6290 field to the SilcChannelEntry in the server. Affected files
6291 silcd/server.c and silcd/idlist.h.
6293 * Added silc_task_unregister_by_context into the file
6294 lib/silcutil/silctask.[ch].
6296 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added SILC_UMODE_GONE mode to indicate when the client is not
6299 present in the SILC network. Added also support to the local
6300 command AWAY that will set this mode. Added support of showing
6301 "xxx is gone" in WHOIS command. The USERS command shows the
6302 gone status as well.
6304 * Fixed setting server and router operator privileges in the
6305 server's UMODE command. Affected file silcd/command.c.
6307 * Merged the SKE KE1 and KE2 payloads into one payload. The
6308 new KE payload is equivalent to the old KE2 payload.
6310 Cleaned up the SKE Start Payload parsing. It now uses the
6311 simple buffer unformatting to do the parsing. A lot faster
6314 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6315 to the SKE that is used to indicate whether both of the SKE
6316 parties should perform authentication. By default only the
6317 responder performs authentication. By setting this flag also
6318 the initiator must do authentication. By default it is unset
6319 since in normal SKE case, client to server connection, only
6320 the responder should do authentication. When doing SKE between
6321 two clients both should perform authentication. Updated the
6322 code and the protocol specs.
6324 * A little fix to IDENTIFY command in the server. Search the
6325 client first by hash not nickname. Affected file is
6328 * Fixed the silc_client_close_connection to support closing
6329 the client to client connections wihtout deleting too much
6330 data. Affected file lib/silcclient/client.c.
6332 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6333 are received if protocol used to be active but is not anymore
6334 the application would crash due to NULL pointer dereference.
6335 Affected files silcd/server.c and lib/silcclient/client.c.
6337 * Added `hash' field to the SilcClientConnection to include
6338 the hash function negotiated in the SKE protocol.
6340 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6341 to set the channel founder authentication data. A client can
6342 claim the founder rights later by providing the authentication
6343 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6344 This way the channel founder can regain the channel founder
6345 privileges even it is left the channel. This works only on
6346 local server and the client must be connected to the same
6347 server to be able to regain the founder rights. Updated the
6348 protocol specs accordingly.
6350 Added support to the CMODE command in the client to set the
6351 founder auth data. Read the README to see how to set it.
6353 Added support to the CUMODE command to claim the founder
6354 rights. Read the README to see how to do it.
6356 Added support for the founder authentication to the Channel
6357 Entry in the server. Affected file silcd/idlist.h.
6359 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6360 server's CMODE command. Affected file silcd/command.c.
6362 * Added the following new functions into lib/silccore/silcauth.[ch]:
6363 silc_auth_get_method and silc_auth_get_data.
6365 * The server now saves the remote hosts public key to the
6366 SilcIDListData pointer. Affected file silcd/protocol.c.
6368 * The normal server now does not remove the channel entry from
6369 the cache if the founder authentication data is set. It used
6370 to remove it if the founder was the last one on the channel on
6371 the server and left the channel. The auth data is saved and
6372 if the channel is re-joined later the old entry is used with
6373 the old auth data. Affected files silcd/command_reply.c and
6376 * Removed the `pkcs' field from the SilcIDListData structure
6377 in the server; it is not used. Affected file silcd/idlist.h.
6379 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6381 * Fixed packet processing on slow links. Partial packets were
6382 never re-processed because the incoming data buffer was cleared
6383 by the application. Application must not directly clear the
6384 sock->inbuf, the packet processing routines handle it. Fixed
6385 this in client library and in server.
6387 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Fixed the WHOIS and IDENTIFY send reply function to really
6390 check whether to send list or just one entry. Affected file
6393 * Cleaned up the LEAVE command's channel key distribution. The
6394 affected file silcd/command.c.
6396 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6397 can enforce the channel mode as well. In that case the ID
6398 includes the ID of the server. The code now enforces the
6399 mode change if the router have different mode than the server.
6401 * The notify client operation with CMODE_CHANGE notify can now
6402 return NULL client_entry pointer if the CMODE was not changed
6403 by client. Application must check for this.
6405 * Added <Server ID> argument to INFO command to support server
6406 info fetching by Server ID.
6408 * Added silc_server_announce_get_channel_users to get assembled
6409 packets of channel users of the specified channel. Affected
6410 file silcd/server.[ch].
6412 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6413 was freed underneath the ID Cache.
6415 * Re-announce clients when the server received CHANNEL_CHANGE
6416 notify from the router. Affected file silcd/packet_send.c.
6418 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6421 crashed since it did not handle the fact that there is no cipher
6422 called "3" and didn't check the error condition. Now fixed.
6424 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6425 flag. It can be used to send message requests.
6427 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Implemented the RESTART command in the client.
6431 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6432 notice type messages. Added notice printing to the user
6435 * The channel keys are not re-generated if the channel's mode
6436 is PRIVKEY, ie private key on the channel exists. Affected
6437 files silcd/server.c and silcd/command.c.
6439 * Fixed a little bug in channel message delivery when channel
6440 private keys are set in the server. Affected file is
6441 silcd/packet_send.c.
6443 * Changed the setting on channel->on_channel = TRUE from the
6444 silc_client_save_channel_key to the JOIN command reply. The
6445 key payload is not received if the private channel key is set.
6446 Affected file lib/silcclient/command_reply.c and the
6447 lib/silcclient/client_channel.c.
6449 * When the CMODE_CHANGE notify is sent and the channel private
6450 key mode is removed the channel key must be re-generated in
6451 other cells as well. Added this support for the router in the
6452 silcd/packet_receive.c.
6454 * Added new local command NOTICE to send notice message on
6455 channel. Affected file silc/local_command.[ch].
6457 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Added new local command ME to the client. It is used to send
6460 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6461 some action. Affected file silc/local_command.[ch].
6463 * Changed channel_message and private_message client operations
6464 to deliver the message flags to the application. Added also
6465 the `flags' arguments to the silc_client_send_channel_message
6466 and silc_client_send_private_message functions. Affected file
6469 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6471 * Redefined the Private Message Payload to support private message
6472 keys and to support the new private message flags. Updated
6473 the protocol specs. Flags makes it possible to have for example
6474 CTCP style messages.
6476 * Added new type SilcPrivateMessagePayload and defined an API
6477 for it in the lib/silcclient/silcprivate.[ch].
6479 * Tested private message private keys successfully. Tested the
6480 private message key set, unset and list commands with the new
6483 * Redefined the Channel Message Payload to include the channel
6484 message flags (equal with private message flags) to support
6485 for example CTCP style messages.
6487 * Defined some of the message (for channel and private message)
6488 flags. Updated the protocol specs and added the flags to the
6489 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6491 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Added SilcKeyAgreementStatus type to the key agreement routines
6494 to indicate the current status and error if one occured.
6495 The status types are defined in the lib/silcclient/silcapi.h.
6497 * Added new local command KEY that is used to set and unset private
6498 keys for channels, set and unset private keys for private messages
6499 with remote clients and to send key agreement requests and
6500 negotiate the key agreement protocol with remote client. The
6501 key agreement is supported only to negotiate private message keys,
6502 it currently cannot be used to negotiate private keys for channels,
6503 as it is not convenient for that purpose.
6505 * Fixed a minor pending callback setting bug in the function
6506 silc_client_get_client_by_id_resolve, now the function works.
6507 Affected file lib/silcclient/idlist.c.
6509 * Added function silc_net_get_local_port to get local bound
6510 port by socket. Added to lib/silcutil/silcnet.[ch].
6512 * Added `sockets' and `sockets_count' fields to the SilcClient
6513 object. They hold the sockets of the listenning sockets in
6514 the client. Listenning sockets may be for example the key
6515 agreement server. Affected file lib/silcclient/client.[ch].
6516 Added functions the silc_client_add_socket and the
6517 silc_client_del_socket. They are exported to the application
6520 * Added ~./silc/clientkeys to support other client's public keys.
6522 * Renamed verify_server_key client operation to verify_public_key
6523 and added one argument to indicate the type of the connection
6524 (server, client etc.).
6526 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Added silc_server_connection_auth_request to handle the
6529 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6530 silcd/packet_receive.[ch].
6532 * Added silc_server_send_connection_auth_request into the
6533 silcd/packet_send.c to send the connection auth request packet.
6535 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6538 * Fixed the public key authentication in responder side in the
6539 server. The `auth_data' pointer includes the SilcPublicKey
6540 not the path to the public key. Affected file silcd/protocol.c.
6542 * Implemented the public key authentication in the initiator side
6543 in the server. Affected file silcd/protocol.c.
6545 * Removed the [RedirectClient] config section from the server
6546 configuration. Is not needed and I don't want to implement it.
6548 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Cleaned up the CMODE command in the server. It now works
6551 correctly and supports all the modes defined in the protocol.
6552 Affected file is silcd/command.c.
6554 * Added `hmac_name' field to the SilcChannelEntry in the server
6555 to hold the default HMAC of the channel. It can be set when
6556 creating the channel (with JOIN command). Affected files
6559 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6560 type to indicate the change of the current cipher and hmac
6561 on the channel. Client can safely ignore the <cipher> argument
6562 (if it chooses to do so) since the CHANNEL_KEY packet will
6563 force the channel key change anyway. The <hmac> argument is
6564 important since the client is responsible of setting the new
6565 HMAC and the hmac key into use.
6567 * Fixed the CMODE command in the client library as well.
6569 * Tested CMODE command in router environment successfully.
6571 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Show the version of the remote client (or server) when connecting
6574 to the server. It is logged to the log file. Affected file
6575 is silcd/protocol.c.
6577 * Fixed the KILLED notify handling in the client library. The
6578 client must be removed from all channels when receiving the
6581 Also, do not remove the client entry when giving the KILL
6582 command but when the KILLED notify is received.
6584 * Removed silc_idlist_find_client_by_nickname from the server.
6585 Not needed anymore. Affected files silcd/idlist.[ch].
6587 * Implemented the CHANNEL_CHANGE notify type handling to the
6588 server. Affected file silcd/server.c.
6592 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Added silc_server_send_notify_invite to send the INVITE
6595 notify between routers.

6606 * Added function silc_server_get_client_resolve to find the
6607 client entry by ID from all ID lists and then resolve it
6608 (using WHOIS) if it cannot be found. Affected file is
6611 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * Implemented the BAN command to the client library.
6615 * The JOIN command in the server now checks the invite list
6618 * Changed the silc_command_reply_payload_encode_va and the
6619 silc_command_payload_encode_va to support that if argument is
6620 NULL it ignores and checks the next argument. Affected file
6621 lib/silccore/silccommand.c.
6623 * Added silc_server_send_notify_ban to send the BAN notify
6624 type between routers.
6626 * Chaned the silc_notify_payload_encode to support that if
6627 argument is NULL it ignores and checks the next argument.
6628 Affected file lib/silccore/silcnotify.c.
6630 * Tested ban lists in router environment successfully.
6632 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Implemented BAN command to the server, in silcd/command.[ch].
6636 * Removed the BAN and INVITE_LIST modes from the CMODE command
6639 * Added function silc_string_match to regex match two strings.
6640 Affected files lib/silcutil/silcutil.[ch].
6642 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6644 * Redefined parts of the SilcChannelEntry in the server to support
6645 the new ban and invite lists.
6647 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Redefined the INVITE command. The same command can be used to
6650 invite individuals to the channel but also to manage the invite
6651 list of the channel (to add to and remove from the invite list).
6652 Updated the protocol specs.
6654 * Added new command SILC_COMMAND_BAN that can be used to manage
6655 the ban list of the channel. Updated the protocol specs.
6657 * Removed the channel modes: the SILC_CMODE_BAN and the
6658 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6659 in the CMODE command. The equivalent features are now available
6660 using INVITE and BAN commands. Updated the protocol specs.
6662 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6663 in the network about change in the current ban list. The notify
6664 type is not used by the client.
6666 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6667 support the invite lists.
6669 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Added new function silc_string_regexify that converts string
6672 including wildcard characters into regex string that can
6673 be used by the GNU regex library. Added into the file
6674 lib/silcutil/silcutil.[ch].
6676 Added silc_string_regex_combine to combine to regex strings
6677 into one so that they can be used as one regex string by
6678 the GNU regex library. Added into the file
6679 lib/silcutil/silcutil.[ch].
6681 Added silc_string_regex_match to match two strings. It returns
6682 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6684 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Imported GNU regex to the soruce tree into lib/contrib.
6687 Fixed some compiler warning from the regex.c.
6689 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6697 in the server, as the `nickname' argument may be binary data
6700 * Added silc_idlist_get_channels to return all channels from
6703 * Implemented LIST command to the server. Affected file is
6706 * Implemented the LIST command to the client library and on the
6709 * Added [<user count>] argument to the LIST command reply.
6710 With private channels the user count is not shown.
6712 * Updated TODO and README.
6714 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * The client entry's data.registered must be TRUE even with
6717 global client entry on global client list. The data.registered
6718 is used to check whether the client is anymore in the network,
6719 for example with WHOWAS command so it must be valid.
6721 * Fixed the WHOWAS command in the server. It now actually works
6722 in router environment. Added function into silcd/command_reply.c
6723 silc_server_command_reply_whowas_save.
6725 * Added silc_idlist_purge function to the silcd/idlist.c
6726 to periodically purge the ID Cache.

6736 they were buggy because of the WHOWAS information.
6738 * Fixed local command MSG to handle the async resolving of
6739 the remote client properly. It used to fail the first MSG.
6740 Affected file silc/local_command.c.
6742 * Added `data_len' field to SilcIDCache context.
6744 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Update TODO. Todo in commands in the server.

6751 used by routers as broadcast packet to inform other routers
6752 about the changed user mode.
6754 Implemented the notify handling in the server. Affected file is
6755 silcd/packet_receive.c. Added the function
6756 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6758 * Added new generic Channel Payload and deprecated the New Channel
6759 Payload. The New Channel Payload is now the generic Channel
6762 * Added new argument `mode' to the silc_server_send_new_channel
6763 as it is required in the Channel Payload now.
6765 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6766 and created a new and real SilChannelPayload to represent the
6767 new generic Channel Payload. Implemented the encode/decode
6768 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6770 * Added silc_server_get_client_channel_list to return the list
6771 of channels the client has joined for WHOIS command reply.
6772 Affected file silcd/server.[ch].
6774 * Implemented the channel list sending in the WHOIS command reply
6775 in server and in the client.
6777 Implemented the channel list displaying on the user interface
6778 as well. Affected file silc/client_ops.c.
6780 * Added silc_channel_payload_parse_list to parse list of Channel
6781 Payloads. It returns SilcDList list of SilcChannelPayloads.
6782 Client for example can use this function to parse the list of
6783 channels it receives in the WHOIS command reply. The caller
6784 must free the list by calling silc_channel_payload_list_free.
6785 Affected files lib/silccore/silcchannel.[ch].
6787 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6806 unknown command. Affected file silcd/command.c.
6808 * All server commands now handle the command identifier the right
6809 way when sending the command reply to the client. The client can
6810 use to identify the command replies with the identifier.
6812 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Added silc_server_get_client_route to resolve the route to
6815 the client indicated by the client ID. Affected file is
6818 * Added silc_server_relay_packet as general function to relay
6819 packet to arbitrary destination. This deprecates functions
6820 like _send_private_message_key, _relay_notify etc. Affected
6821 file is silcd/packet_send.[ch].
6823 Removed silc_server_send_key_agreement,
6824 silc_server_send_private_message_key and
6825 silc_server_packet_relay_notify functions from the file
6826 silcd/packet_send.[ch].
6830 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6831 server. Affected file silcd/packet_receive.[ch].
6833 * Implemented the KILL command to the client. Implemented the
6834 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6835 Affected files lib/silcclient/command[_reply].c and
6836 lib/silcclient/client_notify.c. Implemented the KILL notify
6837 printing in the user inteface.
6839 * Fixed a lot silc_parse_nick memory leaks from the client
6840 library in the file lib/silcclient/command.c.
6842 * Changed the silc_server_send_notify_on_channels's `sender'
6843 argument from SilcSocketConnection to SilcClientEntry to
6844 check the sender as entry and not as connection object and not
6845 to send to the client provided as argument. The affected file
6846 is silcd/packet_send.[ch].
6848 * The notify packets that are destined directly to the client used
6849 to not to be processed by the server. Now changed that and the
6850 server processes all notify packets. After relaying the packet
6851 to the client the notify packet is processed in the server.
6853 * The silc_server_free_client_data now checks whether there is
6854 pending outgoing traffic for the client and purges the data to
6855 the network before removing the client entry.
6857 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6860 an client is killed from the SILC Network. Updated the protocol
6863 Added new function silc_server_send_notify_killed to the
6864 silcd/packet_send.[ch].
6866 * Added function silc_server_packet_relay_notify to relay notify
6867 packets that are destined directly to a client. In this case
6868 the server does not process the notify packets but merely relays
6869 it to the client. Affected file silcd/packet_send.[ch].
6871 Added also silc_server_packet_process_relay_notify to check
6872 whereto relay the notify. Affected file is
6873 silcd/packet_receive.[ch].
6875 * Implemented the KILL command to the server.
6879 * Added the backup schema desgined last fall to the protocol
6880 specs for everyone to see. The specification is in the
6881 *-spec-xx.txt draft and the packet type definitions for the
6882 backup routers is in *-pp-xx.txt draft. Thusly, added also
6883 new packet type SILC_PACKET_CELL_ROUTERS.
6885 * A big security problem in the implementation discovered. The
6886 signoff of an client did not cause new channel key generation
6887 which it of course should've done. The channel keys must be
6888 always re-generated when client leaves (or signoffs) the channel.
6889 The silc_server_remove_from_channels funtion now handles
6890 the channel key re-generation.
6892 * Added `sender' argument to the silc_server_send_notify_on_channels
6893 to not to send the client provided as argument. Affected file
6894 silcd/packet_send.[ch].
6896 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6898 * Implemented OPER and SILCOPER commands into the server and
6901 * Added silc_auth_verify and silc_auth_verify_data to verify
6902 the authentication directly from the authentication payload.
6903 It supports verifying both passphrase and public key based
6904 authentication. Affected file lib/silccore/silcauth.[ch].
6906 * Added `hash' field to the SilcIDListData structure. It is the
6907 hash negotiated in the SKE protocol. Affected file is
6910 * Slight redesigning of the SilcAuthPayload handling routines.
6911 Do not send SilcPKCS but SilcPublicKey as argument.
6913 * Implemented the public key authentication support to the
6914 serverconfig. The public key is loaded from the provided path
6915 and saved as authentication data to void * pointer. Thus,
6916 changed the unsigned char *auth_data to void *auth_data;
6918 * Fixed SHUTDOWN command to send the reply before the server
6919 is shutdown. :) Affected file silcd/command.c.
6921 * Fixed fatal bug in CONNECT command. The hostname was invalid
6922 memory and server crashed. Affected file silcd/command.c.
6924 * Fixed fatal bug in CLOSE command. The server_entry became
6925 invalid but was referenced later in the command. Affected file
6928 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Fixed fatal bug in failure packet handling. Server ignored
6931 the failure and thus crashed when it came.
6935 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6938 that the command may be executed only once in (about) 2 seconds.
6939 The old SILC_CF_LAG flag is same but allows command bursts up
6940 to five before limiting.
6942 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6943 server code. Various commands now includes the CF_LAG_STRICT
6944 flag to disallow any kind of miss-use of the command.
6946 * Fixed the silc_buffer_unformat to not to allocate any data
6947 if the length of the data is zero. It used to allocate the
6948 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6950 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Changed the format of AdminConnection configuration section
6953 in the server. Added username of the admin to the format.
6954 Affected files silcd/serverconfig.[ch].
6956 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6957 to return admin configuration data by host, username and/or
6960 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Implemented WHOWAS command to the server. Added the functions:
6964 silc_server_command_whowas_parse,
6965 silc_server_command_whowas_send_reply,
6966 silc_server_command_whowas_from_client and
6967 silc_server_command_whowas_from_server
6969 * Added <Client ID> argument to the WHOWAS command reply. Updated
6970 the protocol specs accordingly.
6972 * Implemented WHOWAS command and command_reply to the client
6975 Implemented the WHOWAS printing on the user interface.
6977 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Added new argument to the WHOWAS command reply, the real name.
6980 It is an optional argument. Updated the protocol specs.
6982 * Added SilcIDCacheDestructor callback that is registered when
6983 the SilcIDCache is allocated. The callback is called when
6984 an cache entry in the ID Cache expires, or is purged from the
6985 cache. Added into lib/silccore/idcache.[ch].
6987 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6988 to destruct the client entries when the cache entry expires.
6989 Other ID Cache's in server and in the client library ignores
6992 * If the ID Cache entry's `expire' field is zero then the entry
6993 never expires. Added boolean `expire' argument to the
6994 silc_idcache_add function in the lib/silccore/idcache.[ch].
6995 If it is TRUE the default expiry value is used.
6997 * Added silc_server_free_client_data_timeout that is registered
6998 when client disconnects. By default for 5 minutes we preserve
6999 the client entry for history - for WHOWAS command.
7001 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Added support to the server to enforce that commands are not
7004 executed more than once in 2 seconds. If server receives
7005 commands from client more frequently, timeout is registered
7006 to process the commands. Affected file silcd/command.c.
7007 Added new function silc_server_command_process_timeout.
7009 * Changed NICK_NOTIFY handling in client library to check that
7010 if the client's nickname was changed, so there is no need to
7011 resolve anything from the server.
7013 * Removed error printing from the WHOIS and IDENTIFY commands.
7014 If error occurs then it is ignored silently in the client library.
7015 The application, however, may map the received error to
7016 human readable error string. The application currently maps
7017 the NO_SUCH_NICKNAME error to string.
7019 * Made the command status message public to the application. Moved
7020 them from lib/silcclient/command_reply.c to
7021 lib/silcclient/command_reply.h. The application can map the
7022 received command status to the string with the
7023 silc_client_command_status_message function.
7025 * Added check to the server to check that client's ID is same
7026 as the Source ID in the packet the client sent. They must
7029 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7031 * Added dist-bzip hook to the Makefile.am to make bzip2
7032 compressed distributions.
7034 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Server now enforces the maximum length for the nickname and
7037 the channel as protocol specification dictates. 128 bytes for
7038 nickname and 256 bytes for channel name.
7040 * Moved the WHOIS printing to the application. The client libary
7041 does not print out the WHOIS information anymore, the application
7042 must do it. Renamed silc_client_command_reply_whois_print to
7043 the silc_client_command_reply_whois_save.
7045 The client's idle time is also sent to the application now, and
7046 the idle is shown on screen.
7048 * Added silc_client_command_reply_identify_save to save the
7049 received IDENTIFY entries.
7051 * Do not check for channel private keys in message sending and
7052 reception if the channel does not have the PRIVKEY mode set.
7053 Affected file lib/silclient/client_channel.c.
7055 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7058 just surfaced after chaning the JOIN procedure.
7060 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7062 * Added silc_client_get_clients_by_list to get client entries
7063 from Client ID list, that is returned for example by JOIN
7064 and USERS command replies. The application should use this
7065 function for example when JOIN command reply is received to
7066 resolve the clients already on the channel (library does not
7067 do that anymore as USERS command reply is not used in the JOIN
7068 procedure anymore). Affected files lib/silcclient/silcapi.h and
7069 lib/silcclient/idlist.c.
7071 * JOIN command reply and USERS command reply returns now SilcBuffer
7072 pointers instead of unsigned char pointers when returning
7073 the client list and mode list.
7075 * Added <Client ID> argument to the JOIN command reply, mainly
7076 for the server to identify for which client the command was
7077 originally sent. Updated protocol specs accordingly.
7079 * Added SilcDlist private_key pointer to the SilcChannelEntry
7080 in the client to support the channel private keys. Affected
7081 file is lib/silcclient/idlist.h.
7083 * Added SilcChannelPrivateKey argument to the function
7084 silc_client_send_channel_message so that application can choose
7085 to use specific private ke if it wants to. If it is not provided,
7086 the normal channel key is used, unless private keys are set.
7087 In this case the first (key that was added first) is used
7088 as the encryption key.
7090 * Implemented the support for channel private key handling.
7091 Implemented the following functions:
7093 silc_client_add_channel_private_key,
7094 silc_client_del_channel_private_keys,
7095 silc_client_del_channel_private_key,
7096 silc_client_list_channel_private_keys and
7097 silc_client_free_channel_private_keys
7099 Affected file lib/silcclient/client_channel.c.
7101 * Added the support for the private keys in the channel message
7102 sending and encryption and in the message reception and
7103 decryption. Affected funtions are
7104 silc_client_send_channel_message and silc_client_channel_message.
7106 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * Added SKE's key verify callback to the client library's
7109 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7111 * Removed the statement that server (or router) must send USERS
7112 command reply when joining to the channel so that the client
7113 knows who are on the channel. Instead, the client list and
7114 client's mode list is now sent in the JOIN command reply to the
7115 client who joined channel. This is better solution.
7117 * Added function silc_server_get_users_on_channel and function
7118 silc_server_save_users_on_channel to the silcd/server.[ch].
7120 * Removed function silc_server_command_send_users from the
7123 * Do not show topic on the client library anymore. The topic is
7124 sent in the command reply notify to the application and the
7125 application must show the topic now.
7127 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Added client searching by nickname hash into the IDENTIFY and
7130 WHOIS commands in the server as they were clearly missing from
7131 them. Affected file is silcd/command.c.
7133 * Fixed a bug in private message receiving in the client library.
7134 The remote ID was freed and it wasn't supposed, now it is
7137 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Minor fix to the channel payload; allocate the data area, as it
7140 needs to be of specific length.
7142 * If the key agreement port is zero then the operating
7143 system will define the bound port. Affected files are
7144 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7146 * Added new function silc_channel_payload_decrypt into the file
7147 lib/silccore/silcchannel.[ch].
7149 * Moved the channel message etc, check from silc_packet_decrypt
7150 to applications. The library calls now a generic
7151 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7152 when the packet is either normal or special. This was done to
7153 allow more wide range of checking that was not allowed when
7154 the code was in library. Now applications can do virtually any
7155 checks to the packet and return to the library the decision how
7156 the packet should be processed. Affected files are
7157 lib/silccore/silcpacket.[ch].
7159 Added silc_server_packet_decrypt_check to the server and
7160 silc_client_packet_decrypt_check to the client library.
7162 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7163 to send with specified source and destination information.
7165 * Channel message delivery between routers was broken after the
7166 channel key distribution was fixed earlier. The channel key
7167 was used be to distributed to other routers as well which is not
7168 allowed by the protocol. Now this is fixed and channel keys
7169 really are cell specific and the channel message delivery between
7170 routers comply with the protocol specification.
7172 * Fixed various commands in server to check also the global list
7173 for the channel entry and not just the local list. The affected
7174 file silcd/command.c.
7176 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added assert()s to buffer formatting and unformatting routines
7179 to assert (if --enable-debug) when error occurs. Affected
7180 file: lib/silcutil/silcbuffmt.c.
7182 * Changed to auto-reconnect to check whether the remote host is
7183 router and register the re-connect timeout if it is. It used
7184 to check that whether we are normal server, but router must do
7185 auto-reconnect with another router as well. Affected file
7188 * Removed the [<key len>] option from CMODE command as the cipher
7189 name decides the key length, nowadays. See the defined ciphers
7190 from the protocol specification.
7192 * Added [<hmac>] option to the CMODE command to define the HMAC
7193 for the channel. Added SILC_CMODE_HMAC channel mode.
7195 * Added [<hmac>] option for the JOIN command so that user can
7196 select which HMAC is used to compute the MACs of the channel
7199 * Added Hmac field to the Channel Message Payload. The integrity
7200 of plaintext channel messages are now protected by computing
7201 MAC of the message and attaching the MAC to the payload. The
7202 MAC is encrypted. Now, it is clear that this causes some
7203 overhead to the size of the packet but rationale for this is that
7204 now the receiver can verify whether the channel message decrypted
7205 correctly and also when private keys are set for the channel the
7206 receiver can decrypt the packet with several keys and check from
7207 the MAC which key decrypted the message correctly.
7209 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7210 lib/silccrypt/silccipher.[ch].
7212 * Added silc_hash_len to return the digest length into the
7213 lib/silcrypt/silchash.[ch].
7215 * Rewrote parts of Silc Channel Payload interface in the
7216 lib/silccore/silcchannel.[ch]. The encode function now also
7217 encrypts the packet and parse function decrypts it.
7219 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7221 * Fixed a minor formatting bug in the SKE's key material processing.
7222 It actually might have processed the keys wrong way resulting
7225 * Redefined the mandatory HMAC algorithms and added new algorithms.
7226 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7227 and hmac-md5 truncated to 96 bits. The mandatory is now
7228 hmac-sha1-96. Rest are optional (including the one that used
7229 to be mandatory). Rationale for this is that the truncated HMAC
7230 length is sufficient from security point of view and can actually
7231 make the attack against the HMAC harder. Also, the truncated
7232 HMAC causes less overhead to the packets. See the RFC2104 for
7235 * Added new [hmac] configuration section. The SKE used to use
7236 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7237 is of course wrong. The official names that must be proposed in
7238 the SKE are the ones defined in the protocol specification
7239 (hmac-sha1-96 for example). The user can configure any hmac
7240 using any hash function configured in the [hash] section. At
7241 least, the mandatory must be configured.
7243 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7245 * Added HMAC list to the SKE proposal list. It has now both
7246 hash algorithm list and HMAC list. This makes the protocol
7247 incompatible with previous versions. The SKE now seems to work
7248 the way it is supposed to work, for the first time actually.
7250 * Defined plain Hash algorithms to the protocol specification.
7253 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Implemented support for key agreement packets into the server.
7256 Added functions silc_server_key_agreement and
7257 silc_server_send_key_agreement. Other than these functions,
7258 server has nothing to do with this packet.
7260 * Added support for private message key packets into the server.
7261 Added functions silc_server_private_message_key and
7262 silc_server_send_private_message_key.
7266 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7267 called in the protocol's final callback instead in the END
7268 protocol state. This makes a little more sense and in the same
7269 time in client we can use the same protocol routines for normal
7270 key exchange and to key agreement packet handling as well.
7272 * Added to both client's and server's KE protocol context the
7273 SilcSKEKeyMaterial pointer to save the key material. We will
7274 bring the key material to the protocol's final callback by doing
7275 this. The final callback must free the key material.
7277 * Added SKE's packet_send callback into client's KE protocol
7278 context so that the caller can choose what packet sending function
7279 is used. This way we can use different packet sending when
7280 doing normal SKE when doing key agreement packet handling (in
7281 the key agreement packet handling we do not want to encrypt
7284 * Implemented the responder side of the key agreement routines
7285 in the client. The client can now bind to specified port and
7286 accept incoming key negotiation. The key material is passed
7287 to the application after the protocol is over.
7289 * Implemented the processing of incoming Key Agreement packet
7290 in the client. Added function silc_client_key_agreement to
7293 * Implemented the intiator side of the key agreement routines
7294 in the client. The client can now initiate key agreement with
7295 another remote client. The key material is passed to the
7296 application after the protocol is over.
7298 * Created client_keyagr.c to include all the key agreement
7301 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7302 SILC_TASK_CALLBACK except that it is not static.
7304 * Created client_notify.c and moved the Notify packet handling
7305 from the client.[ch] into that file.
7307 * Created client_prvmsg.c and moved all private message and
7308 private message key routines from the client.[ch] into that file.
7310 * Create client_channel.c and moved all channel message and
7311 channel private key routines from the client.[ch] into that file.
7313 * Changed silc_client_get_client_by_id_resolve to resolve with
7314 WHOIS command instead of IDENTIFY command, in the file
7315 lib/silclient/idlist.c.
7317 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Implemented the SKE's responder side to the Client library.
7321 * When FAILURE is received to the protocol do not trust it
7322 blindly. Register a timeout to wait whether the remote closes
7323 the connection as it should do it, only after that process the
7324 actual failure. This was changed to both client and server.
7326 * Added client_internal.h to include some of the structures
7327 there instead of client.h in lib/silcclient/.
7329 * Added function silc_task_unregister_by_callback to unregister
7330 timeouts by the callback function.
7332 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Some "Incomplete WHOIS info" errors has been appearing on the
7335 log files. Took away the entry->userinfo check from WHOIS
7336 reply sending. The entry->userinfo is now " " if client did not
7337 provide one. I thought this was fixed earlier but something
7338 is wrong still. Let's see if the error still appears.
7340 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * Fixed a minor bug in the login when the channel key is
7343 re-generated in the server. It used to generate the key in
7344 wrong order and thus caused problems in the channel traffic.
7346 * Fixed a minor bug in channel key distsribution after
7347 KICK command. The key was not sent to the router even though
7350 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7352 * Added silc_ske_process_key_material_data as generic routine
7353 to process any key material as the SILC protocol dictates. The
7354 function is used by the actual SKE library but can be used by
7355 applications as well. This relates to the private message keys
7356 and the channel private keys since they must be processed the
7357 same way the normal SILC session keys. The protocol dictates
7358 this. Affected files: lib/silcske/silcske.[ch].
7360 Added also silc_ske_free_key_material to free the
7361 SilcSKEKeyMaterial structure.
7363 * Defined silc_cipher_set_key function to set the key for
7364 cipher without using the object's method function. The affected
7365 files: lib/silccrypt/silccipher.[ch].
7367 * Implemented silc silc_client_add_private_message_key,
7368 silc_client_add_private_message_key_ske,
7369 silc_client_del_private_message_key,
7370 silc_client_list_private_message_keys and
7371 silc_client_free_private_message_keys functions in the
7374 Added functions silc_client_send_private_message_key to send
7375 the Private Message Key payload and silc_client_private_message_key
7376 to handle incoming Private Message Key payload.
7378 * Added Cipher field to the Private Message Key payload to set
7379 the cipher to be used. If ignored, the default cipher defined
7380 in the SILC protocol (aes-256-cbc) is used.
7382 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7384 * Removed lib/silcclient/ops.h file.
7386 Redefined parts of the SILC Client Library API. Created new
7387 file silcapi.h that deprecates the ops.h file and defines the
7388 published Client Library API. Defined also private message key
7389 API and channel private key API into the file.
7391 This is the file that the application must include from the
7392 SILC Client Library. Other files need not be included by
7393 the application anymore.
7395 * Added new key_agreement client operation callback and also
7396 defined the Key Agreement library API for the application.
7398 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7400 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7401 is used by clients to request key negotiation between another
7402 client in the SILC network. If the negotiation is started it
7403 is performed using the SKE protocol. The result of the
7404 negotiation, the secret key material, can be used for example
7405 as private message key.
7407 Implemented the Key Agreement payload into the files
7408 lib/silccore/silauth.[ch].
7410 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Redefined ciphers for the SILC protocol. Added some new ciphers
7413 and defined the key lengths for the algorithms. Changed the
7414 code accordingly. The default key length is now 256 bits.
7416 * Fixed SKE key distribution function silc_ske_process_key_material
7417 when the key length is more than 128 bits. The default key
7418 length in SILC is now 256 bits.
7420 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7421 to indicate unsupported algorithm.
7423 * Renamed rijndael.c to aes.c and all functions as well.
7425 * Fixed a long standing channel key setting bug in client library.
7426 Weird that it has never surfaced before.
7428 * Fixed bug in channel deletion. If the entire channel is removed
7429 then it must also delete the references of the channel entry
7430 from the client's channel list as the client's channel entry and
7431 the channel's client entry share same memory.
7433 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7435 * Implemented CONNECT and SHUTDOWN commands in the client.
7437 * Implemented CLOSE command to the client.
7439 * Added the function silc_idlist_find_server_by_name into the
7440 files silcd/idlist.[ch].
7442 Added the function silc_idlist_find_server_by_conn into the
7443 files silcd/idlist.[ch].
7445 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * DIE command was renamed to SHUTDOWN. Updated the both code
7450 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7451 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7453 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7456 * Added function silc_server_create_connection function to create
7457 connection to remote router. My server implementation actually
7458 does not allow router to connect to normal server (it expects
7459 that normal server always initiates the connection to the router)
7460 so the CONNECT command is only good for connecting to another
7463 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7466 or some other client was kicked from the channel.
7468 Implemented the handling of the notify type to both client
7471 Implemented silc_server_send_notify_kicked to send the KICKED
7472 notify. It is used to send it to the server's primary router.
7474 * Implemented the KICK command into server and client.
7476 * Added `query' argument to the silc_idlist_get_client function
7477 to indicate whether to query the client from server or not if
7480 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7481 to indicate that the client is not channel founder.
7485 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Removed the rng context from SilcPacketContext structure and
7488 changed that the packet routine uses the Global RNG API.
7490 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * Added support for quit message that client can "leave" on the
7493 channel when it quits the SILC. It is ditributed inside the
7494 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7496 Added silc_server_free_client_data that will take the
7497 signoff message as argument.
7499 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7501 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Updated parts of the protocol specification to keep it up
7506 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7509 payloads in one packet.
7511 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7512 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7513 use now the new List flag.
7515 * Also deprecated the following packet types: REPLACE_ID,
7516 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7518 * Added list support for Notify packet in server.
7520 * Added silc_server_send_notify_channel_change to send the
7521 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7522 the silc_server_send_replace_id.
7524 * Added silc_server_send_notify_nick_change to send the
7525 NICK_CHANGE notify type. Deprecates the function
7526 silc_server_send_replace_id.
7528 * Added silc_server_send_notify_join to send the JOIN notify type.
7529 Deprecates the function silc_server_send_new_channel_user.
7531 * Added silc_server_send_notify_leave to send LEAVE notify type.
7532 Deprecates the function silc_server_send_remove_channel_user.
7534 * Added silc_server_send_notify_cmode and
7535 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7536 types. Deprecates the silc_server_send_set_mode function.
7538 * Added SERVER_SIGNOFF notify type to indicate that server has
7539 quit. This means that all clients on the channel from that
7540 server will drop. This can be also used when netsplit happens.
7542 Deprecated REMOVE_ID packet type since it is not needed anymore
7545 Added silc_server_send_notify_server_signoff to send the
7546 SERVER_SIGNOFF notify type. Deprecates the function
7547 silc_server_send_remove_id.
7549 Added also silc_server_send_notify_signoff to send the
7550 SIGNOFF notify type.
7552 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7553 SILC protocol from this day on. Changed the protocol
7554 specification as well.
7556 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7557 notify type. It is used between routers to notify about
7558 topic changes on a channel.
7560 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7563 * Partly updated the protocol specification to comply with the
7564 changes now made. It is still though a bit outdated.
7566 * The JOIN notify type now takes one extra argument <Channel ID>.
7567 The packet used to be destined to the channel but now the
7568 JOIN type may be sent as list thus it is impossible to
7569 destine it to any specific channel. By adding this argument
7570 it is again possible.
7572 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7574 * Added CREDITS file. The CHANGES and CREDITS file will appear
7575 in the distribution as well.
7577 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7579 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7580 types in the server's silcd/packet_receive.c.
7582 * Implemented CMODE and CUMODE to work in router environment.
7584 * Fixed minor encoding and decoding buglet from the
7585 lib/silccore/silcmode.c.
7587 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7590 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7592 * Changed all SilcConfigServer* and silc_config_server* to
7593 SilcServerConfig* and silc_server_config*, respectively.
7596 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Associated the ID (client or server ID) to the Authentication
7599 Payload to avoid any possibility of forging. Updated the
7600 protocol specification and the code accordingly.
7602 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7604 * The RSA key length is now save to the RsaKey context in the
7605 key generation process in lib/silccrypt/rsa.c. The key length
7606 is now used to figure out the maximum size of the block allowed
7607 to be encrypted/signed.
7609 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7610 is equivalent to the silc_mp_mp2bin but does not allocate any
7613 * Changed silc_mp_mp2bin API to take length argument. If it is
7614 non-zero then the buffer is allocated that large. If zero, then
7615 the size is approximated using silc_mp_sizeinbase, which however
7618 * Created Global RNG API which is global RNG that application can
7619 initialize. After initializing, any routine anywhere in the
7620 code (including library) can use RNG without allocating a new
7621 RNG object. This was done to allow this sort of use of the
7622 RNG in code that has no chance to allocate RNG object. All
7623 applications currently allocate this and many routines in the
7624 library use this. Affected file lib/silccrypt/silcrng.[ch].
7626 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7627 it to use the Global RNG API.
7629 * Defined Authentication Payload into protocol specification that
7630 is used during SILC session to authenticate entities. It is
7631 used for example by client to authenticate itself to the server
7632 to obtain server operator privileges.
7634 Implemented this payload into the lib/silccore/silcauth.[ch].
7635 Implemented also routines for public key based authentication
7636 as the new protocol specification dictates.
7638 Moved definitions of different authentication methods from
7639 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7641 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7642 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7643 silc_pkcs_verify_with_hash functions into the file
7644 lib/silccrypt/silcpkcs.[ch].
7646 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * The client entry's userinfo pointer must be always valid.
7649 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7650 will fail since it requires the userinfo. Now, the userinfo
7651 is allocated as "" if actual userinfo does not exist. Actually,
7652 it must exist and it is totally Ok to drop client connections
7653 that does not announce the userinfo. However, we will make
7654 this workaround for now.
7656 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7657 to return the remote port by socket.
7659 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7661 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7662 SILC_SERVER_PENDING_EXEC and added an new macro
7663 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7664 data or when error occurs while processing the pending command.
7666 Added new argument `destructor' into silc_server_command_pending
7667 and to the SilcServerCommandPending object. This destructor is
7668 now called after calling the pending callback or if error occurs
7669 immediately. If error occurs the actual pending callback won't
7670 be called at all - only the destructor. The destructor may be
7671 NULL if destructor is not needed.
7673 All this applies for client library code as well. Similar
7674 changes were made there as well for the pending commands.
7676 In the client, the application must now allocate the
7677 SilcClientCommandContext with the silc_client_command_alloc
7680 * Added reference counter to the SilcServerCommandContext. Added
7681 function silc_server_command_alloc and silc_server_command_dup
7684 Same type of functions added to the client library for the same
7687 * Removed the cmd_ident from IDListData away since it is now
7688 global for all connections. It is the command identifier used
7689 in command sending and with pending commands. The affected file
7692 * Added reference counter to the SilcSocketConnection objecet to
7693 indicate the usage count of the object. The object won't be
7694 freed untill the reference counter hits zero. Currently only
7695 server uses this, and client ignores it. The client must be
7696 set to use this too later. The affected files are
7697 lib/silccore/silcsockconn.[ch]. Added also the function
7698 silc_socket_dup to increase the reference counter.
7700 This was mainly added because it is possible that the socket
7701 is removed underneath of pending command or other async
7702 operation. Now it won't be free'd and proper DISCONNECTING
7703 flags, etc. can be set to avoid sending data to connection that
7704 is not valid anymore.
7706 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7707 the connection. After that it sets SILC_SET_DISCONNECTED.
7708 It is, however, possible that the socket data is not still freed.
7709 The silc_server_packet_process now checks that data is not
7710 read or written to connection that is DISCONNECTED. The socket
7711 get's freed when the reference counter hits zero.
7713 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7715 * Changed the client operation API: channel_message operation's
7716 `sender' is now the client entry of the sender, not the nickname
7717 and the `channel' is the channel entry, not the channel name.
7719 In the private_message operation the `sender' is now also the
7720 client entry of the sender not the nickname.
7722 Affected file is lib/silcclient/ops.h and all applications
7723 using the client operations.
7725 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7727 * Moved the calling of ops->connect() from connect_to_server_final
7728 into receive_new_id functin since that is the point when the
7729 client is actually allowed to send traffic to network. The
7730 affected file is lib/silcclient/client.c.
7732 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7734 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7735 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7736 (if needs broadcasting) instead of broadcasting the packets one
7737 by one which would make a burst in the network traffic.
7739 * Added `broadcast' argument to the functions in silcd/server.[ch]
7740 silc_server_create_new_channel[_with_id] to indicate whether
7741 to send New Channel packet to primary router.
7743 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Added new function into the silcd/server.[ch] files:
7746 silc_server_create_new_channel_with_id to create new channel with
7747 already existing Channel ID.
7749 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7750 lib/silccore/silcpacket.h. This packet is used t send list of
7751 Set Mode payloads inside one packet. Server uses this to set
7752 the modes for the channels and clients on those channels, that it
7753 announced to the router when it connected to it. The protocol
7754 specification has been updated accordingly.
7756 * The silc_server_new_channel did not handle the packet coming
7757 from normal server as it normally does not send that. However,
7758 when it announces its channels it does send it. Implemented
7759 the support for that.
7761 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7762 into the file lib/silccore/id.h.
7764 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7766 * Fixed memory leaks in the functions silc_idlist_del_client,
7767 silc_idlist_del_channel and silc_idlist_del_server in the file
7768 silcd/idlist.c. All of those leaked like a sieve.
7770 * Fixed some small memory leaks in the client's function
7771 silc_client_notify_by_server.
7773 * Added functions into silcd/server.c: silc_server_announce_clients,
7774 silc_server_announce_channels and silc_server_announce_server.
7775 These functions are used by normal and router server to announce
7776 to its primary router about clients, channels and servers (when
7777 router) that we own. This is done after we've connected to the
7780 These functions effectively implements the following packet types:
7781 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7782 and SILC_PACKET_NEW_ID_LIST.
7784 * Added new functions into the silcd/packet_receive.[ch]:
7785 silc_server_new_id_list, silc_server_new_channel_list and
7786 silc_server_new_channel_user_list to handle the incoming
7787 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7789 * Added support of changing Channel ID in the function
7790 silc_server_replace_id. If the server that announces a channel
7791 to the router already exists in the router (with same name but
7792 with different Channel ID), router is responsible to send
7793 Replace ID packet to the server and force the server to change
7794 the Channel ID to the one router has.
7796 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7797 client that the Channel ID has been changed by the router. The
7798 normal server sends this to the client. Client must start using
7799 the new Channel ID as the channel's ID.
7801 Implemented handling of this new type into lib/silcclient/client.c
7802 into the function silc_client_notify_by_server.
7804 * Added new function silc_idlist_replace_channel_id into the files
7805 silcd/idlist.[ch] to replace the Channel ID.
7807 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7809 * Call silc_server_command_identify_check always when processing
7810 the IDENTIFY command in silcd/command.c
7812 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7814 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7815 send keepalive packets. The packet can be sent by clients,
7816 servers and routers.
7818 Added function silc_socket_set_heartbeat into the file
7819 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7820 If not set, the heartbeat is not performed. The actual
7821 heartbeat is implemented in the low level socket connection
7822 library. However, application is responsible of actually
7825 Added silc_server_send_heartbeat to send the actual heartbeat
7826 packet into silcd/packet_send.[ch]. Server now performs
7827 keepalive with all connections.
7829 * Added silc_task_get_first function into lib/silcutil/silctask.c
7830 to return the timeout task with shortest timeout. There was a bug
7831 in task unregistration that caused problems. TODO has been
7832 updated to include that task system must be rewritten.
7834 * The client library will now resolve the client information when
7835 receiving JOIN notify from server for client that we know but
7836 have incomplete information.
7838 * Rewrote parts of silc_server_remove_from_channels and
7839 silc_server_remove_from_one_channel as they did not remove the
7840 channel in some circumstances even though they should've.
7842 * Encryption problem encountered in server:
7844 The LEAVE command used to send the Channel Key packet to the
7845 router immediately after generating it. However, the code
7846 had earlier sent Remove Channel user packet but not immediately,
7847 ie. it was put to queue. The order of packets in the router
7848 was that Channel Key packet was first and Remove Channel User
7849 packet was second, even though they were encrypted in the
7850 reverse order. For this reason, MAC check failed. Now, this
7851 is fixed by not sending the Channel Key packet immediately but
7852 putting it to queue. However, this is more fundamental problem:
7853 packets that are in queue should actually not be encrypted
7854 because packets that are sent immediately gets encrypted
7855 actually with wrong IV (and thus MAC check fails). So, packets
7856 that are in queue should be encrypted when they are sent to
7857 the wire and not when they put to the queue.
7859 However, the problem is that the current system has not been
7860 designed to work that way. Instead, the packet is encrypted
7861 as soon as possible and left to the queue. The queue is then
7862 just purged into wire. There won't be any fixes for this
7863 any time soon. So, the current semantic for packet sending
7866 o If you send packet to remote host and do not force the send
7867 (the packet will be in queue) then all subsequent packets to the
7868 same remote host must also be put to the queue. Only after the
7869 queue has been purged is it safe again to force the packet
7872 o If you send all packets immediately then it safe to send
7873 any of subsequent packets through the queue, however, after
7874 the first packet is put to queue then any subsequent packets
7875 must also be put to the queue.
7877 Follow these rules and everything works fine.
7879 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7881 * Added new function silc_server_remove_clients_by_server to
7882 remove all client entries from ID list when the server connection
7883 is lost. In this case it is also important to invalidate all
7884 client entires as they hold the invalid server entry. This
7885 fixes fatal bug when server has lost connection and will reconnect
7888 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Made some sanity checks to silc_server_daemonise like to check
7891 whether the requested user and group actually exists.
7893 * Added sanity check to SKE's silc_ske_responder_finish to check
7894 that the public and private key actually is valid.
7896 * Invalidate the client's nickname when receiving Replace ID
7897 packet and the Client ID is being replaced. This means that the
7898 server will query the nickname if someone needs it (client)
7901 * Sort the ID Cache in client library when the ID Cache data
7902 has changed (needs sorting).
7904 * Do not allow for SILC client to create several connections to
7905 several servers. The client does not support windows right now
7906 and generating multiple connections causes weird behaviour.
7908 Irssi-silc client does support windows and can handle several
7909 connections without problems, see: www.irssi.org and SILC plugin.
7911 * Fixed some places where client was added to the IDList. The
7912 rule of thumb is following (in order to get everything right):
7913 If the client is directly connected local client then the
7914 `connection' argument must be set and `router' argument must be
7915 NULL to silc_idlist_add_client function. If the client is not
7916 directly connected client then the `router' argument must
7917 bet set and the `connection' argument must be NULL to the
7918 silc_idlist_add_client function.
7920 * The funtion silc_server_packet_send_local_channel actually did
7921 not check whether the client was locally connected or not. It
7922 does that now. Fixed a bug related to LEAVE command.
7924 * Fixed Remove Channel User payload parsing bug in server's
7925 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7927 * The server's silc_server_save_channel_key now checks also the
7928 global ID list for the channel as it might not be in the local
7929 list. Fixed a bug related to LEAVE command.
7931 * Is this the end of the [<unknown>] buglet that has been lurking
7932 around for a long time? A little for loop fix in server's
7933 silc_server_command_whois_parse that is used by both IDENTIFY
7934 and WHOIS command. At least, this was a clear bug and a cause
7935 of one type of [<unknown>] buglet.
7937 * WHOIS and IDENTIFY commands call the function
7938 silc_server_command_[whois/identify]_check function even if
7939 we are not router server.
7941 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7943 * Added --with-gmp configuration option. If set the GMP
7944 is always compiled in the SILC source tree. If not set then
7945 it is checked whether the system has the GMP3 installed. If
7946 it has then the GMP won't be compiled (the system's headers
7947 and library is used), if it doesn't have it then the GMP is
7948 compiled in the SILC source tree.
7950 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7952 * Changed RSA private exponent generation to what PKCS #1
7953 suggests. We try to find the smallest possible d by doing
7954 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7955 not security fix but optimization.
7957 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7959 * Added new config entry [Identity] to fork the server and run
7960 it as specific user and group. A patch from Bostik.
7962 * Imported Dotconf configuration library into lib/dotconf.
7963 This will be used to create the SILC configuration files later.
7964 It will appear in the distsribution after this commit.
7966 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7968 * A big code auditing weekend happening. Auditing code for
7969 obvious mistakes, bugs and errors. Also, removing any code
7972 Removed files for being obsolete:
7974 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7975 inline in the file lib/silcutil/silcbuffer.h)
7977 o lib/silcutil/silcbufutil.c (the header has inline versions)
7979 Changed code to fix possible error conditions:
7981 o The buffer formatting routines now check that the destination
7982 buffer really has enough space to add the data. This applies for
7983 both buffer formatting and unformatting
7984 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7985 unformatting was changed to accomodate following rules:
7986 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7987 sent to the function while XXX_*STRING will not allocate or copy
7988 the data into the buffer. Instead it sets the pointer from the
7989 buffer into the pointer sent as argument (XXX_*STRING used to
7990 require that the pointer must be allocated already). This change
7991 makes this whole thing a bit more consistent and more optimized
7992 (note that the data returned in the unformatting with XXX_*STRING
7993 must not be freed now). The routines return now -1 on error.
7995 o Tried to find all code that use buffer_format and buffer_unformat
7996 and added return value checking to prevent formatting and
7997 especially unformatting errors and possible subsequent fatal
8000 o Changed ske->x and ske->KEY to mallocated pointers in
8001 lib/silcske/silcske.h. Fixed possible data and memory leak.
8003 o Added return value checking to all *_parse* functions. Fixed
8004 many memory leaks as well.
8006 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8007 so that buffer overflows would not happen. All code now also
8008 checks the return value as it can fail.
8010 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8012 * Added reconnection support to server if the normal server looses
8013 its connection to the router (for example if router is rebooted).
8014 The server performs normal reconnection strategy implemented
8015 to the server. Affected file silcd/server.c.
8017 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * Added new packet type SILC_PACKET_SET_MODE that is used to
8020 distribute the information about changed modes (for clients,
8021 channels and clients channel modes) to all routers in the
8022 network. Updated the protocol specification accordingly.
8024 Added functions into silcd/packet_send.c and
8025 silcd/packet_receive.c: silc_server_send_set_mode,
8026 silc_server_set_mode.
8028 Added new files silcmode.[ch] into lib/silccore that implements
8029 the encoding and decoding of Set Mode Payload. Added new type
8030 SilcSetModePayload. Moved the definitions of different modes
8031 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8033 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Oops, a little mistake in server's connection authentication
8036 protocol. The protocol is not ended with FAILURE but with
8037 SUCCESS if the authentication is Ok. :) Affected file is
8040 * Implemented NICK_CHANGE notify handling in server in the file
8041 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8042 the local clients on the channel. After the changing nickname
8043 in router environment snhould work and the [<unknown>] nickname
8044 should appear no more.
8046 The silc_server_replace_id function that receives the Replace ID
8047 payload now sends the NICK_CHANGE notify type also in the file
8048 silcd/packet_receive.c
8050 * Changed WHOIS and IDENTIFY command to support the maximum amount
8051 of arguments defined in protocol specs (3328 arguments). This
8052 fixed a bug that caused problems when there were more than three
8055 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8057 * Added extra parameter, command identifier, to the
8058 silc_client_send_command so that explicit command identifier
8061 Changed that ID list routines uses specific command identifier
8062 when sending WHOIS/IDENTIFY requests to the server so that they
8063 can be identified when the reply comes back.
8065 Affected files lib/silcclient/command.[ch],
8066 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8068 * Added `sender' argument to silc_server_packet_send_to_channel
8069 to indicaet the sender who originally sent the packet to us
8070 that we are now re-sending. Ignored if NULL. Affected file
8071 silcd/packet_send.[ch].
8073 * Added some server statistics support in silcd/server_internal.h
8074 SilcServerStatistics structure and around the server code. Also
8075 send some nice statistics information when client is connecting
8078 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * Fixed channel ID decoding in server's JOIN command reply in
8081 silcd/command_reply.c
8083 * Fixed braodcasting of replace ID payload to not to send it if
8084 we are standalone server in silcd/packet_receive.c.
8086 * Fixed all channel message sending routines to not to send
8087 packets to clients that has router set, since they are routed
8088 separately in the same function earlier. Affects file
8089 silcd/packet_send.c and all channel packet sending functions.
8091 * In USERS reply, res_argv[i] are not allocated, the table
8092 is allocated. Thus changed that free the table, not its
8095 * In server's whois_check and identify_check if the client is
8096 locally connected do not send any WHOIS commands - they are not
8099 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8101 * Fixed some minor bugs in client when sending WHOIS command. The
8102 arguments was in wrong order.
8104 * Removed statis function add_to_channel from server in
8105 silcd/command.c that was previously used with the joining but
8108 * Tested USERS command in router environment successfully with two
8109 routers, two servers and two clients.
8111 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8113 * Reorganized the USERS command and command reply in client library
8114 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8115 When the command is given by user we register a pending command
8116 callback that will reprocess the command after the reply has been
8117 received from the server. When reprocessing the packet we then
8118 display the information. Thus, the USERS information is displayed
8119 now in the command callback instead of in the command reply
8120 callback. The processing of the command is same as previously
8121 when server has sent the command reply in the JOINing process.
8123 * Added to USERS command in silcd/command_reply.c to join the client,
8124 we didn't use to know about, to the channel after we've created
8125 a client entry for it. Also, for clienet we did know already still
8126 check whether it is on the channel or not and add it if not.
8128 * Removed silc_server_command_join_notify as the function and its
8131 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Changed the client's pending command handling to the same as the
8134 server's pending command handling. It is also now possible to
8135 execute command reply functions from other command reply
8136 function as the function callbacks for commands and command
8137 replies are one and same. The pending commands are not static
8138 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8139 in client connection context. Thus, pending commands are server
8140 connection specific as it is convenient.
8142 Changed the function silc_client_command_pending and
8143 silc_client_command_pending_del and added new function
8144 silc_client_command_pending_check. Removed the
8145 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8148 * Added cmd_ident, current command identifier, to the client
8149 connection context in lib/silcclient/client.h to keep track on
8150 command identifiers used in command sending. Client's command reply
8151 function handling now supports the mandatory command identifiers.
8153 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8154 funtions in client to fully support pending command callbacks.
8156 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8157 as one of the arguments to the application in the command reply
8160 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8161 before first releasing SILC but came back. Now it is removed again
8162 and should come back nomore. The FORWARDED flag was used only
8163 by the JOINing procedure by forwarding the command packet to router.
8164 Now, the JOINing procedure has been changed to more generic (due
8165 to various router environment issues) and FORWARDED is not needed
8166 anymore for anything. The protocol specification is yet to be
8169 Now, removed silc_server_packet_forward from server and the flag
8170 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8172 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8174 * Renamed NAMES command to USERS command. The NAMES was named that
8175 due to historical reasons. Now it is renamed. Also, rewrote
8176 parts of the USERS command. The nickname list is not sent anymore
8177 by the server. Only Client ID and mode lists are sent in the USERS
8178 command. Changed this also to the protocol specification.
8180 The client now resolves the names and stuff after it receives
8181 the USERS list from the server when joining to the channel.
8183 * WHOIS and IDENTIFY commands has been changed to support multiple
8184 Client ID's per command. One can now search for multiple users
8185 in the network by sending only one WHOIS or IDENTIFY command.
8186 Changed the code and the protocol specifications.
8188 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8189 uses silc_server_command_whois_parse to parse the request. */
8191 * If normal server, do not parse the WHOIS and IDENTIFY requests
8192 before sending it to the router. Saves some time.
8194 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8196 * Fixed JOIN command on client library. Wrong number of arguments
8197 used to crash the client.
8199 * Added silc_server_channel_has_global function to check whether
8200 channel has global users or not.
8202 * Added silc_server_channel_has_local function to check whether channel
8203 has locally connected clients on the channel.
8205 * The silc_server_remove_from_one_channel now checks whether the
8206 channel has global users or not after given client was removed from
8207 the channel. It also checks whether the channel has local clients
8208 on the channel anymore. If it does not have then the channel entry
8209 is removed as it is not needed anymore.
8211 * The silc_server_notify now checks on JOIN notify whether the joining
8212 client is one of locally connected or global. If it is global then
8213 the channel has now global users on the channel and that is marked
8214 to the channel entry. Also, it now saves the global client to
8215 global list who is joining and JOINs it to the channel. This is
8216 for normal server, that is.
8218 Changed silc_server_send_notify_on_channel,
8219 silc_server_packet_relay_to_channel and
8220 silc_server_packet_send_to_channel check if we are normal server
8221 and client has router set (ie. global client) do not send the
8222 message to that client, as it is already routed to our router.
8224 * Implemented LEAVE notify type handling in silc_server_notify
8227 * Tested LEAVE command in router environment successfully. Tested
8228 with two routers, two servers and two clients.
8232 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8234 * Implemented SIGNOFF notify type handling in silc_server_notify
8237 * silc_server_remove_id now removes the client entry from all channels
8238 it has joined and thusly sends SIGNOFF notify type.
8240 * Rewrote the NAMES list generation in server by removing two excess
8241 loops. The lists are created now inside one loop.
8243 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * silc_server_remove_channel_user checks now also global list
8246 for channel and client.
8248 * silc_server_new_channel_user checks now both local and global
8249 list for channel and client. Fixed a bug in client id decoding.
8250 Used to decode wrong buffer.
8252 * silc_server_channel_message checks now both local and global
8253 list for channel entry.
8255 * Tested channel joining (hence JOIN) in router environment
8256 successfully. Tested with two routers, two servers and two
8259 * Tested channel message sending in router environment successfully.
8261 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Added silc_server_save_channel_key into server.[ch] to save the
8264 received channel key in Channel Key payload processing. It is
8265 also used in JOIN command reply handling.
8267 Equivalent function silc_client_save_channel_key added into
8268 client.[ch] into client library.
8270 * Changed JOIN command reply to send information whether the channel
8271 was created or not (is existing already) and the channel key
8272 payload. Changed protocol specs accordingly.
8274 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8275 the request was sent by ID and not by nickname. Crashed on
8278 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8281 now correctly save the received data.
8283 * silc_server_free_sock_user_data now notifies routers in the
8284 network about entities leaving the network.
8286 At the same time implemented functions silc_server_remove_id
8287 and silc_server_send_remove_id to receive and send REMOVE_ID
8288 packets. The packet is used to notify routers in the network
8289 about leaving entities. The ID removed will become invalid in
8292 * Added function silc_idlist_del_server into server. Removes and
8293 free's server entry from ID list.
8295 * silc_server_private_message function now checks, if we are router,
8296 that the destination ID really is valid ID, naturally.
8298 * In router when NEW_ID packet is received (for new client) the
8299 hash of the Client ID is saved in the ID Cache but the
8300 client->nickname is set to NULL, instead of putting the hash
8303 IDENTIFY command now also checks that client->nickname must be
8304 valid. If it is not if will request the data from the server who
8305 owns the client. Added new function
8306 silc_server_command_identify_check.
8308 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8309 to set the command to already allocated Command Payload.
8311 * Tested private message sending in router environment with two
8312 routers, two servers and two clients. Fixed minor bugs and now
8315 * Fixed segfault from client's NAMES command. Used to crash if
8318 * Forwarded packets must not be routed even if it is not destined
8319 to the receiver. Changed server code comply with this.
8321 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8323 * Added `require_reverse_mapping' boolean value to ServerParams
8324 structure. If TRUE (not default) the server will require that
8325 the connecting host has fully qualified domain name.
8327 If the reverse mapping is not required and hostname could not be
8328 found the IP address is used as hostname.
8330 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8332 * Implemented version string checking to both client and server.
8333 The check is incomplete currently due to the abnormal version
8334 strings used in development version of SILC.
8336 * Changed all command functions in server to use the new
8339 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8341 * Changed char *data to unsigned char *data in ID Cache system to
8342 support binary data as ID Cache data. Changed code to support
8343 binary data in lib/silccore/idcache.c.
8345 * Renamed silc_server_packet_relay_command_reply to
8346 silc_server_command_reply as it is normal packet receiving
8347 function. Rewrote the function to accept command replys for
8348 servers and not only for clients.
8350 * Mark remote router always as registered server if we are connecting
8351 to it. Otherwise, commands sent by the router to us are ignored.
8353 * All ID List find routines now returns the ID Cache Entry pointer
8354 as well if requested.
8356 * WHOIS command works now in router environment, tested with two
8357 routers, two servers and two clients.
8359 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8360 in router environment (as it is almost equivalent to WHOIS) but
8361 hasn't been tested thoroughly. Added new functions:
8363 silc_server_command_identify_parse
8364 silc_server_command_identify_send_reply
8365 silc_server_command_identify_from_client
8366 silc_server_command_identify_from_server
8368 * Disabled route cache adding because adding two different ID's with
8369 same IP replaces the old cache entry thus giving wrong route.
8370 The entry->router->connection is always the fastest route anyway
8371 so route cache may not be needed. Of course, new routes maybe
8372 established after receiving the ID when the entry->router->connection
8373 might not be anymore the most optimal.
8375 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8377 * Add route cache for received ID for fast routing.
8379 * Added silc_server_packet_route to route received packet on router
8380 that is not destined to us.
8382 * Renamed silc_server_get_route to silc_server_route_get.
8384 * Added id_string and id_string_len fields into SilcServer to
8385 include encoded ServerID for fast comparing without excess
8386 encoding of the ID's.
8388 * Cleaned up WHOIS command on server side. Added following static
8391 silc_server_command_whois_parse
8392 silc_server_command_whois_check
8393 silc_server_command_whois_send_reply
8394 silc_server_command_whois_from_client
8395 silc_server_command_whois_from_server
8397 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8398 arguments in command replies. All command functions should be
8399 updated to use this macro.
8401 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8403 * Minor typo fixes on command reply handling on server.
8405 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8407 * Added silc_server_command_add_to_channel internal routine to add
8408 the client to the channel after router has created the channel and
8409 sent command reply to the server.
8411 * Added generic silc_server_send_command to send any command from
8414 * Use static buffer with ID rendering instead of duplicating data.
8416 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8418 * Fixed a channel user mode bug when joining to a channel server gave
8419 everybody channel founder rights, oops.
8421 * We mark ourselves as the router of the incoming server connection
8422 if we are router ourselves. This way we can check in some packet
8423 sending functions whether it is locally connected server. For
8424 incoming router connections we put NULL.
8426 * For router sending packets locally means now always sending the
8427 packet cell wide; to local clients and local servers. For normal
8428 server sending packet locally means sending it to only local
8431 * Fixed the JOIN command to really work in router environment. If the
8432 channel is created it is always created by the router. Router is
8433 also responsible of making the initial joining to the channel,
8434 sending JOIN notify to the sending server and distributing
8435 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8436 does not exist server doesn't do anything else but forward the
8437 command to the router which performs everything.
8439 * Added silc_server_send_channel_key function to send the Channel Key
8442 * Added silc_server_create_channel_key to create new channel key. The
8443 channel key is now re-generated everytime someone joins or leaves
8444 a channel, as protocol dictates. Note: channel->key_len is the
8447 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8449 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8450 packet_receive.[ch] to separate packet sending and receiving
8451 routines. The server.[ch] now includes everything else including
8452 actual packet processing (writing and reading data) and other
8455 Renamed silc_server_private_message_send_internal to
8456 silc_server_send_private_message. The routine is still though
8457 used only to relay private messages as server does not send
8458 private messages itself.
8460 Renamed silc_server_new_channel to silc_server_create_new_channel
8461 and added new function sicl_server_new_channel that handles the
8462 incoming New Channel packet. Added also new sending function
8463 silc_server_send_new_channel to send New Channel Payload.
8465 * Added new function silc_server_notify to process incoming notify
8466 packet to the server/router. Server may then relay the notify
8467 to clients if needed.
8469 * Added new function silc_server_new_channel_user to process incoming
8470 New Channel User packet. Router will redistribute the packet and
8471 send JOIN notify to its local clients and locally connected servers
8472 if needed. Normal server will send JOIN notify to its local client
8473 on same channel when received this packet. Added also corresponding
8474 sending function silc_server_send_new_channel_user to sent the
8477 * Added boolean route argument to send_notif_to_channel and
8478 packet_send_to_channel functions to attempt to route the packet
8479 if it is TRUE and send only locally if it is FALSE.
8481 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8483 * silc_server_replace_id now broadcasts the received replace ID
8484 packet if it is not broadcast packet already. The router must
8485 broadcast to inform other routers about changed ID.
8487 * Added backpointer to server's router into SilcServer context in
8488 silcd/server_internal.h.
8490 * Fixed silc_server_packet_broadcast to send correct broadcast
8493 * The channel key is now distributed to the local client as soon
8494 as it is received from the router (in router environment) so that
8495 no other packet may be sent for the channel until client has
8498 * silc_server_remove_channel_user now broadcasts the received
8499 Remove Channel User packet if it is not broadcast packet already.
8500 The router must broadcast to inform other routers about removed
8503 * Added users field into SilcPacketContext that is a reference count
8504 of the context. One can increase the reference count by calling
8505 silc_packet_context_dup which is now changed to just increase the
8506 reference count instead of duplicating the data. The reference
8507 count is decresed by calling silc_packet_context_free that will
8508 free the data after the reference count hits zero.
8510 For now on the packet context and everything allocated into it
8511 (including the raw packet from network) must be freed by calling
8512 the new silc_packet_context_free function. Added also new function
8513 silc_packet_context_alloc that must be used now to allocate the
8514 context. This also means that if a routine is asynchronous from
8515 silc_[client/server]_packet_parse_type the packet context must
8516 be duplicated by calling silc_packet_context_dup. Otherwise it
8517 gets free'd after silc_[client/server]_packet_parse_type returns.
8518 Also, one must remember that if packet is duplicated then its
8519 reference count must be decresed by calling the free function as
8520 many times as it was duplicated.
8522 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8523 from both client and server.
8525 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8527 * Made joining to a channel working in router environment.
8529 * Cleaned up JOIN command on server side and create function
8530 silc_server_command_join_channel internal routine to make the
8533 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8535 * Changed silc_command_pending list to SilcDList. Also, added
8536 `ident' field to SilcServerCommandPending structure to identify
8537 the reply and to call correct callback.
8539 Added silc_server_command_pending_check function to replace the
8540 corresnponding macro. The silc_command_pending list is not
8543 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8544 to set identifier to previously allocated Command Payload. It
8545 is used to set identifier for command when resending Command
8548 * Added silc_command_payload_encode_payload to encode Command
8549 Payload buffer from SilcCommandPayload structure.
8551 * Added silc_argument_payload_encode_payload to encode Argument
8552 payload buffer from SilcArgumentPayload structure.
8554 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8556 * Changed WHOIS command to support router connection on server side.
8557 The whois request is always sent to router unless the server is
8558 standalone server. After server has received the reply from the
8559 router will it send the reply to the client.
8561 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8562 broadcast received broadcast packet. The function is used only
8563 by router. The broadcast packet is always sent to the router's
8566 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8567 render given ID to printable string, for log files for example.
8569 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8571 * Made basic router to router connections working. At least they
8572 can now connect to each other but nothing really works the way
8573 they are supposed - yet.
8575 * Added new initiator token to RouterConnection configuration
8576 file in silcd/serverconfig.[ch]. It is used to tell whether we
8577 are the initiator to the remote router or whether we'll expect
8578 the other end to connect.
8580 * Moved registering of listener task to silc_server_init, hence
8581 the server starts listenning as soon as it is run, even if it
8582 does not have connections to other routers. Let's see how well
8585 * Changed default connection retry timeouts for more suitable in
8588 * Removed cipher and such arguments from silc_idlist_add_client
8589 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8590 Added new function silc_idlist_add_data to add the keys and stuff
8593 * Added SilcIDListData structure and added it to SilcClientEntry
8594 and SilcServerEntry as their first field in the structure. This
8595 way we can explicitly cast the ID entries to the SilcIDListData
8596 structure and get common data for the entries. In past, we had
8597 to first check what type of connection it is and then cast it to
8598 correct ID entry type. Now, we can directly cast the opaque
8599 pointer to the SilcIDListData (no matter what ID entry it actually
8600 is) and get the data needed.
8602 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8604 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8605 in some circumstances even if threre were timeout tasks, though not
8606 IO tasks, but tasks anyway. Now fixed.
8608 * Defined SilcServerConnection structure to hold connection specific
8609 stuff about directly connected servers and routers. The definition
8610 is currently in silcd/server_internal.h. I thought about having
8611 a bit more important role fro this struct but for now it is used
8612 only when connecting to other server (or router actually).
8614 * Added connecting retry support in server when connecting to
8615 router(s). The retry feature implement exponential backoff
8616 algorithm. Also, added SilcServerParams structure to hold default
8617 parameters for server. For now, it include these retry settings
8618 and are hard coded. After server is moded to be as Silc Server
8619 Library this structure will be more important.
8621 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8623 * Changed client librarys channel->clients table to SilcList and
8624 changed code accordingly.
8626 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8628 * Changed client's channel table to SilcList and changed code
8629 accordingly. Also changed SilcChannelClientEntry to include back-
8630 pointer to the channel so that client entry can use that structure
8631 as list as well and we have fast cross-reference to the channel.
8632 This change dramatically decreased the complexity of channel
8633 handling with client entry and vice versa (removed one extra
8634 loop when searching for channel entry from many functions).
8636 * Changed server->sim from table to SilcDList and changed code
8639 * NAMES command can now be used from user interface. It will show
8640 the user list on the channel, neatly.
8642 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8643 Code now saves realname of the user if it becomes available.
8645 * Renamed configure.in to configure.in.pre and made ./prepare
8646 script to automatically add correct version string to
8647 configure.in which it creates from configure.in.pre.
8649 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8651 * NAMES command reply now shows users mode with the nickname when
8654 * Moved silc_client_ch[u]mode[_char] functions from
8655 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8656 place sucks, they are utility functions and should be in some
8659 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8661 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8664 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8668 * Added TRQ (efficient deque and list library) into lib/trq. This is
8669 a very good list library that is currently used in the SILC. Defined
8670 SilcList API over the library because I didn't like the API very
8671 much. See lib/trq/silclist.h for the API and examples of how to
8672 use the API. Fixed various places in the code to use the new
8673 SilcList API. The SilcList is meant for lists that has a structure
8674 already defined as a list. It is not suitable to add just some
8675 context to the list (in TRQ, the context is the list actually).
8677 So, I defined SilcDList that can be used for the purpose where
8678 predefined list structure does not exit. This can be used as
8679 such list. Now some context just can be added to the SilcDList.
8680 Currently this list is not used in the SILC just yet, though there
8681 are a lot places where this can replace dynamically allocated
8682 tables and I will fix these places, later, to use SilcDList.
8683 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8684 and use TRQ internally).
8686 Also fixed some annoying warning messages that the original TRQ
8687 code generated. Also minor changes to TRQ's Makefile.in.
8689 * Added support for querying by Client ID to both WHOIS and
8690 IDENTIFY commands into server, as required by the protocol.
8692 * Removed method function pointers from SilcBuffer structure. They
8693 weren't used to anything and just increased the context size for
8694 no good reason. This change also made silc_buffer_alloc and
8695 silc_buffer_free functions inline functions.
8697 * Disabled command flooding detection support until it's fixed so
8698 that it accepts commands in but does not execute them more than once
8701 * Added silc_net_localhost(), to return local hostname, into
8702 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8703 that must be initialized before calling silc_client_init.
8705 * Added new function: silc_server_send_notify_on_channels to send
8706 notify messages to all channels client has joined. It is assured
8707 that the message is sent only once per client.
8709 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8710 lib/silcutil/silcutil.[ch] as silc_format function. The new
8711 function is generic and is used by server as well, not only by
8712 the logging routines.
8714 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8715 the provided version string was not acceptable. Added new function:
8716 silc_ske_check_version into lib/silcske/silcske.h. The function
8717 must be implemented by the application (client or server) and it
8718 does not reside in the SKE library. The function checks the version
8719 string remote end sent.
8721 * Added back pointers (to opaque context and to SilcSocketConnection)
8722 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8724 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8725 duplicate packet context structure.
8727 * Changed `notify' client operation to send same arguments as client
8728 receives from server except for ID's. ID's are mapped to correct
8729 ID entry and that is returned. Also, if channel entry is not sent
8730 by server but the notify is for channel the channel entry is sent
8731 to application (otherwise application doesn't know that it is for
8732 channel (library gets it from packet's Destination ID)).
8734 * Added silc_client_remove_from_channels into client library to
8735 remove a client from all channels it has joined to. Used when
8736 received SIGNOFF notify from server. Added also new function
8737 silc_client_replace_from_channels to replace old ID entry with
8738 new ID entry on all channels. Used when received NICK_CHANGE
8741 * Fixed ID Cache list handling in silc_idlist_get_client in
8742 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8743 to get (or query) client by ID.
8745 * Updated TODO list.
8747 * Added connection authentication status message defined by the
8748 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8749 support for these into the code in client and server side.
8751 * Added generic function silc_client_send_command to send any command
8752 with variable argument list. Application should use this function
8753 to send commands if the command functions provided by the library
8754 does not suite for the application's user interface needs.
8756 * Added new `failure' client operation. Application is notified about
8757 received failure packet if client is executing a protocol. In this
8758 case the protocol's execution has failed.
8760 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8761 is required by the protocol.
8763 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8764 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8767 * Added status flag to SilcSKE object to indicate realtime status
8768 of the SKE protocol.
8770 * Application receives now exactly same command reply arguments as
8771 the library receives from server. However, if ID is received the
8772 corresponding ID entry is returned to the application (eg. Client
8773 ID is mapped to correct SilcClientEntry entry and that is returned).
8774 Changed command_reply client operation due to this change.
8776 * Changed all ID's in commands and in command replys as ID Payloads.
8777 Change affected both client and server side codes.
8779 All ID's sent in SILC network (with execption of ID's in SILC
8780 Packet header) are sent in ID Payload to support variable length
8783 * Server now notifies nick changes and notifies all clients on
8784 the channels about the new nickname (about the new Client ID,
8787 * Implemented CMODE command to change channel modes. Supports all
8788 channel modes defined by the protocol specs except ban and invite
8789 lists. (Also, private channel key mode is supported but support for
8790 setting private channel key in client is missing, thus, this mode
8791 has no effect on client side (except that server requires that the
8792 client uses private channel key and normal channel traffic does not
8795 Also, invite mode works per se, but INVITE command does not work
8796 yet correctly, so you can set channel as invite only channel but
8797 inviting clients to the channel does not work (it is yet to be
8798 thought what's the best way to do it).
8800 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8801 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8802 Implemented CUMODE command to change user's mode on the channel.
8803 Supports all modes defined by the protocol specs.
8805 * Added NAMES command reply to return users modes on the channel.
8807 * Removed unnecessary and slow ciphers from lib/silccrypt.
8809 * Set SO_KEEPALIVE option to connection sockets by default.
8811 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8813 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8814 redefined the Notify Payload into protocol specs.
8816 * Added silc_id_payload_parse_id to get ID directly from raw
8819 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8821 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8822 accept searching by Client ID as well.
8824 * Added support for LEAVE and SIGNOFF notify types in client library.
8826 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8827 to parse ID Payload from raw data.
8829 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8831 * Added flags parameter into silc_ske_assemble_security_properties
8832 function in lib/silcske/silcske.[ch].
8834 * Changed notify client operation to fit better for notify messages
8835 sent by server. The notify payload received from server is now
8836 passed to the application (after parsing it to SilcNotifyPayload).
8837 It is application's responsibility to retrieve the arguments
8838 from the payload and show the message the way it wants. The message
8839 sent by server is implementation specific.
8841 * Changed public keys to comply with the protocol specification.
8842 Old public keys are not supported anymore and are not compatible.
8844 * Removed nickname from Channel Payload as the latest draft removed
8845 it. The client must resolve the nickname from the NAMES command
8846 reply received when it joined the channel.
8848 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8850 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8852 * Fixed some errors in protocol specification drafts.
8854 * Created lib/silccore/silcnotify.c to implement Notify Payload
8855 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8856 generic payloads described by protocol specifications. The file
8857 includes implementations for ID Payload and Argument Payload.
8859 * Changed Command Payload implementation to use the new Argument
8860 Payload. Changed command_xxxx_payload to command_payload_xxxx
8861 to comply with SILC coding conventions.
8863 * Added suppport for Argument Payload handling in Notify Payload
8864 implementation as protocol requires it. Added the new support
8865 into server and client lib as well.
8867 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8869 * Added support for multiple nicknames on same channel. [n] is
8870 added locally to the nickname if there are more than one same
8871 nicknames on the channel.
8873 * Server now sends all nicknames that matched WHOIS request.
8874 Client also shows the list received from server.
8876 * Added TOPIC command to client side. User can now set and show
8877 current topic on channel.
8879 * Added MOTD command to client and server. Also, server sends the
8880 motd when client connects to the server.
8882 * Changed version strings to comply ISO 8601.
8884 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8886 * Fixed protocol error handling in client library. It should now
8887 cope even if the SKE fails for some reason.
8889 * Made new protocol specification drafts for submitting to IETF.
8891 * Implemented TOPIC command to server in silcd/command.c.
8893 * Added two new notify types into lib/silccore/silcnotify.h:
8894 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8895 notify nickname change and topic setting/change on a channel.
8897 * API change of command_reply operation in client library. The
8898 application gets now the status type received from server as well.
8900 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8902 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8904 * Cras fixed and optimized the packet handling even further and
8905 it should work now. Minor change to the prototype of function
8906 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8908 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8910 * Added new function into lib/silcutil/silcschedule.[ch]:
8911 silc_schedule_with_fd to select() a specified fd. The function
8912 returns after timeout expires or data arrives or goes. The
8913 function is used by packet routines to wait that all data is
8914 received from network.
8916 * Fixed data reading from network in lib/silccore/silcpacket.c.
8917 The code now assures that all data is read from the fd and then
8918 continues packet processing. This was a bug fix since the code
8919 used to drop some data in some circumstances.
8921 * Added new function into lib/silcclient/client.[ch]:
8922 silc_client_start_key_exchange to start key exchange after
8923 connection has been established to server. The code internally
8924 now uses this funtion but its main purpose was to provide it
8925 for applications that perform their own connecting. After
8926 application has created a connection it merely calls this
8927 function to start the key exchange between client and server.
8928 The library takes care of everything else after that.
8930 Updated also lib/silcclient/README to explain the usage of
8933 * Do not send to application information that connection has
8934 been established. Application gets notified it by connect
8937 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8939 * Applied cras's patch to add silc_schedule_one function. The
8940 function runs scheduler once and returns.
8942 * Fixed the scheduler after cras messed it up. The timeout
8943 handling works now as it's supposed to work.
8945 * Added into lib/silccore/ silcnotify.h to include notify
8946 message types support. Changed silc_server_send_notify*
8947 functions, in server.[ch], to support those new notify types.
8948 Added the support for the notify types into client library,
8949 as well. Added new notify client operation into ops.h in
8952 * Changed silc_server_packet_send_to_channel to send normal
8953 packets instead of just channel message packets. The function
8954 is now used to send the notify packets to channels. It is not
8955 used to send channel message packets anymore, as server never
8958 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8959 va_arg()s as it seems to require it nowadays. I guess, if SILC
8960 is compiled with older va_arg() the new code should work anyway.
8962 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8964 * Splitted core library. Core library (lib/silccore) includes
8965 now only SILC protocol specific core (and common) components.
8966 Created new utility library (lib/silcutil) that includes more
8967 generic purpose stuff. The stuff for util library was taken
8968 from the old core library. This was minor and easy split.
8970 * Created SILC Client Library (lib/silcclient) that includes
8971 implementation of the SILC client without user interface. This
8972 was major move from silc/ directory. The code has been changed
8973 so that it is transparent towards the user interface. The
8974 silc/ directory includes now the same user interface as before
8975 and it uses the new client library. Read lib/silcclient/README.
8976 Basicly, the client library performs everything else related
8977 to SILC except user interface handling. Also, configuration
8978 files are considered to be part of user interface and library
8979 does not handle them.
8981 This change also changed a lot of structures, function naming etc.
8982 Most important change was that SilcClientWindow object was
8983 renamed to SilcClientConnection in the client library. Created
8984 also new file lib/silcclient/ops.h. Also added new files
8985 silc/local_command.[ch] and silc/client_ops.[ch].
8987 All these changes were made to make it easier for user interface
8988 designers to create what ever user interface for the SILC client
8991 It is also expected that the server will be moved to lib
8992 directory as well and SILC Server Library will be created;
8993 sometimes in the future.
8995 * Removed Local commands from lib/silccore/silccommand.h as
8996 they are application specific and new client library does not
8997 handle any of those anymore.
8999 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9000 old client implementation in silc/.
9002 * Added support for callback functions in SILC_LOG_* macros.
9003 Application can now set its own callbacks that will be called
9004 instead of using the default functions that will always print
9005 the debug messages to stderr (or stdout). Also, debugging can
9006 now be disabled by setting silc_debug to FALSE and re-enabled by
9007 setting it to TRUE. Note, that logging will still work even
9008 if debugging is disabled.
9010 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9011 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9012 silc_log_reset_debug_callbacks.
9014 * To enable debugging in silc client one must give now -d
9015 option on command line.
9017 * Changed silc_schedule_init to automatically allocate task queues
9018 if they are not allocated before calling it.
9020 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9022 * Added GMP 3.1 into math library.
9024 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9026 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9027 a channel in SILC network. The packet is used by servers and
9028 routers to notify other routers that user has left a channel.
9029 This little feature was missing until now. Added the feature
9030 to protocol specification as well.
9032 Added functions: silc_server_send_remove_channel_user and
9033 silc_server_remove_channel_user into server.[ch].
9035 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9036 lib/silccore/silcpacket.h. However, they are not implemented
9039 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9041 * Fixed joining to a channel and sending channel messages
9042 between server and router. The channel message sending should
9043 now work inside a cell.
9045 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9047 * Fixed the private message sending between server and router.
9048 The private message sending should now work inside a cell.
9050 * Added silc_server_replace_id into server.[ch] to replace
9051 existing ID in the SILC network.
9053 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9054 and silc_idlist_replace_server_id into idlist.[ch] in server.
9056 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9058 * Fixed the server to server connections. Server can again now
9059 connect to router. Router to router connections probably does
9062 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9064 * Added dynamic protocol registering support. Now protocols can
9065 registered and unregistered on the fly. Patch by cras.
9067 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9069 * Added lib/contrib directory to hold routines that some platforms
9070 don't have but are needed by SILC.
9072 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9073 into lin/contrib to provide getopt() and getopt_long() for
9074 those who don't have it.
9076 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9078 * Added AWAY command to client. When away message is set and
9079 client receives a private message packet the client automatically
9080 replies to the sender with the away message.
9082 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9083 bug seemed to be the cause of recent problems when compiling
9086 * Added version detection support to SKE protocol specification
9087 and added the new changes to the SKE implementation as well.
9088 There were other minor changes in the SKE protocol as well.
9090 Many changes in lib/silcske/silcske.[ch] and in
9091 lib/silcske/payload.[ch].
9093 * Added ^U functionality, clear input line. Patch from cras.
9095 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9097 * Mainly small bugfixes on core library. Fixed some debugging
9098 logging and buffer overflow in silclog.c.
9100 * Updated config.sub and config.guess on the distribution tree.
9102 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9104 * Added command lagging support in server. Client may execute
9105 commands now only once in two seconds.
9107 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9109 * Optimized packet reception. MAC computation and checking is now
9110 also more optimized. A lot previously duplicated code is now
9111 used as generic by both client and server.
9113 * Fixed key pair generation in clientutil.c
9115 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9117 * Added into lib/silccore/silcbufutil.[ch] new function;
9118 silc_buffer_realloc.
9120 * Moved generic packet sending/encryption functions to
9121 lib/silccore/silcpacket.[ch] from client and server. Some
9122 rewriting of the functions.
9124 * Moved all generic packet reception/decryption functions to
9125 lib/silccore/silcpacket.[ch] from client and server. The
9126 packet processing is now much cleaner in both client and server.
9127 These were major changes in both client and server.
9129 * Created many common functions in server to do packet sending.
9130 Previously code were duplicated a lot, this has been removed
9133 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9135 * Rewrote major parts of the ID cache system. Don't know
9136 whether it is better now or not but at least the API is more
9139 * Major rewrite on ID cache stuff on client because of the ID
9140 cache API changes. Added idlist.c to client.
9142 * Also major rewrite on ID cache stuff on server as well.
9143 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9144 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9145 in hand, instead they are all put into the ID cache system now.
9146 All server_idlist_* routines uses ID cache now instead of
9147 traversing its own lists (those lists does not exist anymore).
9148 SilcIDList though still exists. Also, SilcXXXEntry's are
9151 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9153 * Finally made the SKE implementation compliant to the protocol
9154 specification. All mp integers are now binary encoded as
9155 opposed being HEX encoded.
9157 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9160 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9161 functions: silc_[encode/decode]_pem. Also added function
9162 silc_encode_pem_file to PEM encode with newlines ('\n') for
9165 * SILC public keys are now encoded either PEM or binary. Same
9166 option is for private keys as well. By default private keys
9167 are binary encoded and public keys PEM encoded. Silly HEX
9168 encoding were removed.
9170 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9171 function to create fingerprints.
9173 * Fixed a bug in SHA1; does not change the original data anymore.
9175 * Partly implemented INFO command on client and server side.
9176 Fixed CLEAR command. Changes to SERVER command; show current
9177 server(s) when giving command without arguments. Added
9178 VERSION command to client.
9180 * Added check to server that unregistered connections cannot
9181 execute commands (unless it is specificly allowed).
9183 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9185 * Fixed screen refresh.
9187 * Fixed channel joining bug from client. On some circumstances
9188 client tried to join to a channel it had already joined.
9190 * Added public key verification process into client's protocol.c.
9191 The client now verifies the public key from user and saves
9192 it into ~./silc/serverkeys/ directory.
9194 Added into: clientutil.[ch]: silc_client_verify_server_key.
9196 * Changed SKE protocol's silc_ske_initiator_finish function
9197 to accept callback function that verifies the received public
9198 key. Removed old silc_ske_verify_public_key function.
9200 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9202 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9203 silc_pkcs_private_key[_data]_set.
9205 * Made the password and public authentication more cleaner in
9206 server's protocol.c.
9208 * Removed historic and obsolete protocol `channel_auth' from
9209 both client and server.
9211 * Removed wrong way of sending command status messages from
9212 server to client in server's command.c. The old way violated
9213 protocol specification.
9215 Changes to silccore/silccommand.[ch]: removed
9216 silc_command_encode_status_payload -> not needed anymore,
9217 changed silc_command_encode_payload_va to accept extra
9218 argument on variable argument list. The argument type must
9219 now be provided to the function. Also, added new function:
9220 silc_command_encode_reply_payload_va which is same as
9221 normal command_encode_payload_va except command status type
9222 is provided as extra argument.
9224 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9226 * Added ~./silc directory handling. The directory includes the
9227 public and private keys for the client.
9229 Added silc_client_check_silc_dir, silc_client_create_identifier
9230 and silc_client_load_keys.
9232 * Implemented SILC protocol compliant public key. Added public
9233 and private key saving to and loading from files.
9235 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9236 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9237 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9238 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9239 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9241 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9242 silc_pkcs_load_[public/private]_key.
9244 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9246 * Added silc_server_get_route (route.[ch]) to get connection
9247 data for the fastest route for given ID.
9249 * Implemented INVITE command on client and server. The command
9250 were re-defined in the SILC Protocol Specification and the
9251 implementation now complies with the specification.
9253 * Implemented PING command on client and server.
9255 * Implemented NAMES command on client and server. The server side
9256 supports currently only normal server not router server yet.
9257 Some changes to NAMES definition in SILC protocol specification.
9259 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9261 * Implemented LEAVE command on client and server.
9263 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9264 again. This change was made to the protocol as well. Server
9265 should not violate the protocol specification anymore.
9267 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9269 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9270 was tested. SOCKS4 was not but should work anyway.
