1 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Assure that endless loop cannot happen with detached client
4 resolving on normal server. Added idlist status
5 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
6 silcd/idlist.h and silcd/packet_receive.c.
8 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
10 * Incoming file transfer request cannot use same session as
11 the sending session. This can happen when sending file to
12 yourself. Crashed the client on quit. Affected file
13 lib/silcclient/client_ftp.c. Bug #24.
15 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
17 * Implemented the draft-riikonen-precense-attrs draft and
18 the Attribute Payload into the lib/silccore/silcattrs.[ch].
20 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
22 * Distribute the SERVER_SIGNOFF notify also to local backup
23 routers from the primary router. The backup router may not
24 have the signing of local server directly connected and need
25 to know about the signoff. Affected file silcd/server_util.c.
27 * Use the primary router as the origin of the locally connected
28 server when it is disconnecting from the backup router since
29 that's where it really is coming from. Now the clients from
30 the disconnecting server are removed correctly and "shadow"
31 clients are not left to the backup router. Affected file
34 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
36 * If normal server is standalone and found existing but disabled
37 channel, do not re-create the channel since it creates
38 duplicate same channels. Affected file silcd/server.c.
40 * Added anonymous client connections support to server. New
41 "anonymous" configuration option to ConnectionParams section
42 added. If set to true, the username and hostname information
43 of the client will be scrambled and anonymous user mode is
44 set automatically to the user. Affected files are
45 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
47 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
49 * In JOIN notify handling, mark that the cache entry of the
50 client cannot be expired. Can cause crashes on normal
51 server (asserts client->channels). Affected file is
52 silcd/packet_receive.c.
54 * From now on distribution versions are used as protocol versions
55 instead of by default using the Toolkit base version as protocol
56 version. Affected file prepare.
58 * Do not set the locally resolved hostname for local client
59 entry but take what server sends. This way the real hostname
60 is showed in WHOIS for yourself. Affected file is
61 lib/silcclient/idlist.c and lib/silcclient/client.c.
63 * Resolve local info with IDENTIFY when connecting to server.y
65 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
67 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
68 for implied search (not needed on platforms which has native
69 pthreads library). Use --without-pthreads to disable threads.
70 Affected file is configure.in.pre
72 * Fixed --with-iconv on platforms which need to bypass (broken)
73 native iconv(). Affected file is configure.in.pre
75 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
77 * Moved -C option parsing in Irssi SILC client at same time
78 as other options. The UI was initialized earlier and caused
79 problems on command line. Bug #16. Affected file is
80 irssi/src/silc/core/silc-core.c.
82 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
84 * Added global variable silc_log_timestamp that tells silclog
85 wether to print or not the timestamp in the logging files.
86 Affected file lib/silcutil/silclog.[ch].
88 * Added silcd configuration option Timestamp in the Logging
89 section. Affected file silcd/serverconfig.[ch],
90 doc/example_silcd.conf.in.
92 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Fixed fingerprint checking to check for entirely empty
95 fingerprint instead of two first bytes when determining
96 if it is set. Bug #18. Affected file silcd/command.c.
98 * Fixed duplicate PKCS name registering to not allow it.
99 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
101 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
103 * Conditionalize non-gcc compiler optimizations for various
104 platforms, enable those commented out. Cleanups.
105 Affected file lib/silcmath/mpi/configure.in
107 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
109 * silc_rng_exec_command() left zombie processes if command
110 didn't generate any output. Affected file
111 lib/silccrypt/silcrng.c
113 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
115 * Rewrote iconv checking, introduce --with-iconv for systems
116 which rely on libiconv. Check if iconv() provided by libc
117 is good enough, otherwise demand libiconv. Affected file
120 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
122 * Search for ldopen() also in libc. This enables SIM support
123 on *BSD systems. Based on patch from Alex Zepeda. Affected
124 file configure.in.pre
126 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
128 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
129 This fixes prepare on *BSD systems. Affected file
132 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
134 * More fixed for not having purge timeout for global clients
135 that are on channel. Affected files silcd/command_reply.c
138 * Fixed the rekey protocol to work with backup router connections.
139 Rekey packets are now allowed on disabled connections as
140 well. Affected files silcd/packet_send.c and server.c.
142 * Do not switch to be as backup router when shutting down and
143 closing the primary connection. Affected file silcd/server.c.
145 * Fixed memory leaks in backup router deleting. Added
146 silc_server_backup_free to free all data during shutdown of
147 server. Affected files silcd/server_backup.[ch].
149 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
151 * Do not process commands if the sock->user_data is NULL.
152 Affected file silcd/command.c.
154 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Fixed buffer overflow and security problems (loosing bits
157 in CFB encryption) in SILC RNG. Problems reported by
158 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
160 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
162 * Added yet more checks that client is not expired on global
163 list if it is on channels. Affected file is
164 silcd/command_reply.c.
166 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Merged c0ffee's MIME signal patch which adds support for
169 sending also MIME messages in Irssi SILC Client, and handling
170 received MIME messages in a signal (and perhaps doing something
171 to non-textual MIME messages).
173 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Fixed pending command deletion in server and client library
176 to check the whole list instead of breaking after first found.
177 The affected files are silcd/command.[ch] and
178 lib/silcclient/command.[ch].
180 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
182 * Return NO_SUCH_CHANNEL error in USERS for channel that is
183 secret or private, otherwise it's possible to find out
184 whether a secret channel exists or not. Affected file
187 * If CMODE change fails during the mode setting, assure that
188 the old mode mask is set for the channel back. Affected
189 file silcd/command.c.
191 * Fixed passphrase saving on +a channel on normal server
192 after successful JOIN command. Affected file silcd/command.c.
194 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
196 * Remove server/router operator privileges in DETACH command,
197 since it's possible to resume to server where these
198 privileges would not be allowed for the client. Affected
199 file silcd/command.c.
201 * Do not set to wait for backup in rehash of the server.
202 Affected file silcd/server.c.
204 * Do not check listener sockets when counting how many
205 socket connections we have. Affected file is
208 * Do not announce disconnected clients that are remaining
209 in history (for WHOWAS). This is because SIGNOFF notify
210 for these has been sent earlier already. Affected file
213 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
215 * Buffer overflow with CUMODE command's mode->mode character
216 conversion. Reported by Ville Räsänen. Affected file
217 lib/silcutil/silcutil.c.
219 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
221 * Allow heartbeat packets to go disabled connections anyway.
222 Affected files silcd/server.c and silcd/packet_send.c.
224 * Do not broadcast New Channel packets with List flag set
225 in the packet to backup routers. The router must check
226 for the correctness of the packets before sending them.
227 It is possible that router will have enforce Channel ID
228 change and this would cause desync in the backup router.
229 Affected file silcd/packet_receive.c.
231 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
232 are handled in list parsing. They are not list packets
233 anymore. Affected file silcd/packet_receive.c.
235 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
237 * Stop waiting for backup router through the timeout, not
238 directly after backup router has arrived. Affected file
241 * Do not re-create channel keys and send them when removing
242 clients in server shutdown. Affected files are
243 silcd/server_internal.h and silcd/server_util.c.
245 * Notify distribution to backup routers was missing from
246 the silc_server_send_notify_dest function which caused
247 desyncing problems with backup router. Affected file is
250 * The client's channel removing was working wrong on
251 backup router. It assumed that it doesn't know global
252 information but backup router does know. For this reason
253 it could remove channel when it wasn't supposed to do that.
254 Affected file silcd/server.c and silcd/server_util.c.
256 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
258 * Stop for a couple seconds after badkup router has become
259 primary router. Affected file silcd/server.c.
261 * Added silc_server_remove_servers_by_server, which is used
262 to remove servers originated from some other server. Also
263 clients of those servers can be removed too. Affected file
264 silcd/server_util.[ch].
266 * When removing clients after a server has signed of remove
267 also all servers behind that server (unless they are known
268 to be available locally), and send SERVER_SIGNOFF for each
269 of the server separately. Also the signed off clients are
270 sent now separately per signed off server. The affected files
271 are silcd/server.c and silcd/server_util.[ch].
273 * All servers added with silc_idlist_add_server must always
274 have both "router" and "connection" pointers set. Otherwise,
275 bad server entries may be left around in the cache.
276 Affected file silcd/command_reply.c.
278 * Do not create the channel key in NEW_CHANNEL packet
279 processing if the channel is empty. Affected file
280 silcd/packet_receive.c.
282 * Completed backup router support for standalone routers.
283 Supports also servers in the cell that do not use the backup
286 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
288 * Fixed a bug in silc_string_regexify which did not add '^'
289 at the start of each string, and thus the matching was
290 not explicit. For example ban list iikone@*!*@* would
291 match also "priikone", which is wrong, it would have to be
292 *iikone@*!*@* to match also "priikone". Affected
293 file lib/silcutil/unix/silcunixutil.c.
295 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
297 * Enable all local server connections before updating client
298 caches when we've become backup router. Otherwise, signoff
299 packets may not reach the clients. Affected files are
300 silcd/server.c and silcd/server_util.[ch].
302 * Fixed a bug in version string parsing which could crash
303 the program with specially formatted version string.
304 Bug reported and patch provided by Ville Räsänen. Affected
305 file lib/silcutil/silcutil.c.
307 * Handle the disconnection immediately when DISCONNECT
308 packet is received in server. Affected file silcd/server.c.
310 * Primary router now waits a short time (10 seconds) for
311 backup router connection before accepting any other
312 connection (except local). Affected file silcd/server.c,
315 * Fixed a crash in client libary in NICK_CHANGE notify when
316 NICK_CHANGE arrived for client entry we are resolving
317 currently. Affected file lib/silcclient/client_notify.c.
319 * Call the sconn->callback completion even if error had
320 occurred. Start reconnecting always if connection to
321 primary router fails during backup router protocol.
322 Affected files silcd/server.c and server_backup.c.
324 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
326 * Added functions silc_server_send_opers and
327 silc_server_send_opers_notify to send packets stricly
328 to operators. Added macro SILC_SERVER_SEND_OPERS macro
329 to send variable argument notify to operators.
330 Affected files silcd/packet_send.[ch] and silcd/server.h.
332 * Removed UMODE rights checking with UMODE_CHANGE notify.
333 Affected file silcd/packet_receive.c.
335 * Server/router operator now receives notify when network
336 switches to backup router and when it resumes the use of
337 primary router. Affected file silcd/server.c and
338 silcd/server_backup.c.
340 * Fixed the updating of client information after backup
341 resuming protocol is over; update all except local clients
342 to the new primary router. The affected file is
345 * Added support for closing active connections in rehash
346 that were unconfigured by the user. Supports currently
347 closing server and router connections. Affected file
350 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
352 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
355 is NULL since seems that on some platforms NULL is allowed
356 and on some it's not. Fallback encoding is used instead.
357 Affected file lib/silcutil/silcstrutil.c.
359 * Fixed statistics updating for incoming server connection
360 which could cause problems when re-connecting. Affected
363 * Preliminary backup router support for standalone router
364 added. Affected files in silcd/.
366 * Mark server connections in backup router disabled before
367 and after backup protocol. Affected file is
368 silcd/server_backup.c.
370 * Added support for reconnecting to remote server connection
371 even if the protocol fails, and if the configuration wants
372 us to keep trying to connect anyway.
374 Server connection is not allowed to backup router if
375 backup router does not have connection to primary router yet.
377 Affected file is silcd/server.c.
379 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
381 * Added silc_client_udpate_server function to update changed
382 server info. Affected file lib/silcclient/idlist.[ch].
384 * Added check for server entries that are being resolved when
385 notify is received. If being resolved, handle the received
386 notify only after it's resolved so that all notifys are
387 handled in same order as received from the server.
389 Added similar resolver check to channel entries. Every
390 notify that cause resolving of any information that affects
391 channel entry marks the channel entry in waiting state.
392 After whatever resolving is over the waiters are signalled
393 and only then the notifys are handled in the same order
394 as delivered from the server.
396 Affected files are lib/silcclient/idlist.[ch], and
399 * Fixed KILLED notify handling in normal server. Affected
400 file silcd/packet_receive.c.
402 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
403 is locally connected, or was locally connected (but may
404 be detached and connection is not active). Added also
405 SILC_IS_LOCAL for checking this status. Affected files
406 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
407 silcd/server.c and silcd/server_internal.h.
409 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
411 * Don't send or handle TOPIC_SET if topic is already set and
412 is same as being set. Affected files silcd/command.c and
413 silcd/packet_receive.c.
415 * Fixed CMODE change rights checking to work correctly when
416 removing modes by operator. Affected file is
419 * Fixed some handling with New Channel packet in router and
420 fixed some CMODE_CHANGE notify handling in server and router.
421 Affected file is silcd/packet_receive.c.
423 * Changed "disconnect" client operation to include the
424 reason of the disconnection and optional disconnection
425 message. Affected file lib/silcclient/silcclient.h.
427 * Made the compilation of lib/contrib/ stuff conditional.
428 Affected files configure.in.pre, lib/contrib/Makefile.am.
430 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
432 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
433 to the sender of the notify too, to avoid situation where two
434 notifys are in the network at the same time going to oppsite
435 directions. Affected file silcd/packet_receice.c.
437 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Delete the client from channel even if the cilent->id is
440 NULL. It was possible that client was deleted without
441 removing from channels (theoretically at least). Affected
442 file silcd/server.c and silcd/server_util.c.
444 * Free the client data too when resuming is not successful.
445 Affected file silcd/packet_receive.c.
447 * Merged some code from c0ffee's silc-plugin. Affected files
448 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
450 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
451 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
452 to the primary router connection, the other one returns
453 TRUE if packet must be broadcasted to network.
455 * All notifys that are destined to primary router (to network)
456 are now automatically sent to backup routers even if the
457 router is standalone (and has backup router). Affected files
460 * Added --without-irssi and --without-silcd configuration
461 options for disabling the compilation of these applications.
462 Affected file configure.in.pre and prepare.
464 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
466 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
467 UTF-8 encoding and decoding. Added also new encodings
468 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
470 Added also SILC_STRING_LANGUAGE which is language and charset
471 specific encoder and decoer for those platforms that support
472 iconv(). It can convert the UTF-8 to and from the locale
473 specific character set.
475 Affected file lib/silcutil/silcstrutil.[ch].
477 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
479 * Added function silc_get_command_name to the file
480 lib/silcutil/silcutil.[ch].
482 * Improved the server debug output a bit. Affected files are
485 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Save the channel passphrase when received succesful JOIN
488 command reply from router, on normal server. Otherwise
489 joinig +a channels from normal server is not possible.
490 Affected file silcd/command.c.
492 * Fixed a bug in TOPIC_SET notify handling. The notifier
493 may be other than client too, like server or channel.
494 It expected it to always be only client and ignored the
495 notify. Affected file silcd/packet_recieve.c.
497 * Removed some (unnecessary) debug printing from
498 lib/silccore/silcid.c and lib/silccore/silcargument.c.
500 * Do not force CMODE_CHANGE when server is announcing new
503 Router announces stuff only after server reannounces channel
504 after CHANNEL_CHANGE notify.
506 These fixes optimizes the announcing procedure, and perhaps
507 fixes some problems too. Affected file silcd/packet_receive.c.
509 * Fixed SERVER_SIGNOFF sending to local clients. It was
510 totally broken and sent the notify to all local clients,
511 instead of only to those that was on same channel as the
512 signing off clients. Affected file silcd/server_util.c.
514 * Added -D option to server. It can be used to give debug
515 level. The levels are from 0 - 99, and are predefined for
516 smooth server debugging. (see silcd.c for the predefined
517 levels). Affected file silcd/server.c.
519 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Fixed a bug in Irssi SILC client to close the connection
522 properly when disconnecting from server. Affected file
523 irssi/src/silc/core/client_ops.c.
525 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
527 * When authenticating as founder during JOIN command, check
528 that the one authenticating becomes the only founder on the
529 channel. Affected file silcd/command.c.
531 * Better checking for founder mode setting when CUMODE_CHANGE
532 notify is received. Affected file silcd/packet_receive.c.
534 * Close all connections when shutting down the server by sending
535 DISCONNECT packet. Close all listeners too when shutting
536 down the server. Affected file silcd/server.c.
538 * Handle DISCONNECT packet correctly in client library by
539 calling the "disconnect" client operation. Affected file
540 lib/silcclient/client.c.
542 * Handle local errors correctly during resuming. Affected
543 file lib/silcclient/client.c.
545 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
547 * The log file is not dupped internally anymore in
548 lib/silcutil/silclog.c. Fixed memory leaks too.
550 * The scheduler now dispatches all pending timeout tasks
551 when it is uninitialized with silc_schedule_uninit.
552 Affected file lib/silcutil/silcschedule.c.
554 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
556 * Added --enable-stack-trace option to configure. Added
557 memory allocation stack trace support. Added files
558 lib/silcutil/stacktrace.[ch]. Affected files are
559 lib/silcutil/silcmemory.[ch].
561 * Fixed memory leaks from libraries and server. Affected
562 files around the tree.
564 * Reverted back a fix made to CUMODE which broke it.
565 Affected file silcd/command.c.
567 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
570 core library, and implemented it. All textual messages SHOULD
571 use this flag and the message MUST be UTF-8 encoded.
572 All text messages sent by Irssi SILC client are now UTF-8

1094 * Changed the Killer's Client ID in KILLED notify to be just
1095 any ID payload since router server is allowed to kill as well.
1096 Updated protocol specs, client libary and server. Affected
1097 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
1098 and irssi/src/silc/core/client_ops.c.
1100 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1102 * Added new user modes ANONYMOUS for special anonymous servers
1103 that may set the mode for client, and BLOCK_PRIVMSG which
1104 client may set to block incoming private messages unless the
1105 Private Message Key flag is set (using private keys to protect
1106 private messages). Updated protocol specs and code in client
1107 and server and core library. Protocol TODO #23. Affected
1108 files are lib/silccore/silcmode.h, silcd/server.[ch],
1109 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
1110 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
1112 * Added new channel user mode BLOCK_MESSAGES which the client
1113 may set to itself to tell server not send channel messages.
1114 Other packets such as channel key packets are still sent.
1115 Protocol TODO #23. Updated the protocol specs, client and
1116 server. Affected files are lib/silccore/silcmode.h,
1117 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
1118 lib/silcutil/silcutil.c, silcd/command.c, and
1119 silcd/packet_send.c.
1121 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1123 * Redefined the Status Payload to include now two 8 bit fields,
1124 instead of one 16 bit field. This now makes it possible to
1125 send list of errors. Updated the protocol specs and the code
1126 in core library, client library and server. Protocol TODO #1.
1127 Affected files are lib/silccore/silccommand.[ch],
1128 lib/silcclient/command_reply.[ch], silcd/command.c,
1129 silcd/command_reply.c and silcd/packet_receive.[ch].
1131 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1133 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1134 must be handled by the application and should tell the application
1135 that an error message was already printed, and it should print the
1136 config coords (line, filename, ...). Affected files are
1137 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1139 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1140 server config parsing code more readable.
1142 Fixed a bug in the fetch_logging() config callback.
1144 Affected files is silcd/serverconfig.c.
1146 * Drop root privileges when started in foreground. Don't drop them
1147 if debugging also. Affected file is silcd/silcd.c.

1151 * Added more IM-like features by introducing new user modes
1152 for setting various presence information. Added new modes:
1153 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1154 specs and code. Protocol TODO #19. Affected files are
1155 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1156 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1158 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1160 * Added STATS command to the protocol after all, to return
1161 various statistical information about the network. It can
1162 be used by clients to retrieve statistical information, and
1163 servers may use it to to fetch cell and network wide
1164 statistics from router. Updated the protocol specs and
1165 implemented it to the server. Protocol TODO #16.
1166 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1167 silcd/command_reply.[ch].
1169 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1171 * The LIST command reply in client libary now adds new channel
1172 entry if the returned channel doesn't exist yet in cache,
1173 and returns the channel entry to the application in the
1174 command_reply client operation. Affected file is
1175 lib/silcclient/command_reply.c.
1177 * Changed the channel message payload's MAC generation to
1178 include the IV in the MAC as well. This way all relevant
1179 parts of the channel message payload are authenticated also
1180 with the channel message MAC (and not only by packet MAC).
1181 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1182 Affected file is lib/silccore/silcchannel.c.
1184 * Fixed the SKE to save the remote version, since the
1185 silc_ske_parse_version mistakenly checked wrong version,
1186 after it replaced the start payload. Affected files are
1187 lib/silcske/silcske.[ch].
1189 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1192 string utility functions. Added there also new functions
1193 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1194 Affected files lib/silcutil/silcstrutil.[ch].
1196 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1197 files are lib/silcutil/silcstrutil.[ch].
1199 * Defined that the security property fields in SKE SHOULD be
1200 UTF-8 encoded, defined that version string MUST be US-ASCII
1201 encoded, defined that passphrases sent in connection
1202 authentication protocol MUST be UTF-8 encoded. Implemented
1203 these to the client and server. Defined also that other
1204 passphrases sent in the protocol MUST be UTF-8 encoded.
1205 Affected files are lib/silcske/silcske.c,
1206 lib/silcclient/protocol.c, silcd/protocol.c,
1207 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1209 * Changed the silc_client_close_connection interface to not
1210 need the SilcSocketConnection which should not be visible
1211 to application. Affected files are lib/silcclient/client.c
1212 and lib/silcclient/silcclient.h.
1214 * Rewrote the text for Private Message Key Payload in the
1215 protocol specification. Protocol TODO #11.
1217 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1219 * Upgraded the protocol version to 1.1, updated protocol specs
1222 * Added the nickname as new argument to NICK_CHANGE notify and
1223 added it to protocol specs and implemented it to client and
1224 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1225 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1226 lib/silcclient/client_notify.c.
1228 * Added the killer's client ID to the KILLED notify and added
1229 it to protocol specs and implemented it to client and server.
1230 Protocol TODO #13. Affected files are silcd/command.c,
1231 silcd/packet_receive.c, packet_send.[ch],
1232 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1233 The killer's client entry is now returned to application in
1234 the `notify' client operation.
1236 * Fixed the Max Argument fields that had too large value set
1237 in the protocol specs. Protocol TODO #14.
1239 * Added the LEAVE command reply to return the ID of parted
1240 channel. Updated protocol specs and implemented it to the
1241 client and server. Protocol TODO #15. Affected files are
1242 silcd/command.c, lib/silcclient/command_reply.c. The channel
1243 entry is now returned to application in the `command_reply'
1246 * Rewrote the version SKE version checking in client libary
1247 and in server to use the silc_parse_version_string. Affected
1248 files are lib/silcclient/protocol.c, silcd/protocol.c.
1250 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1251 commands that was missing it, and updated protocol specs and
1252 the server implementation. Protocol TODO #10. The affected
1253 file is silcd/command.c.
1255 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1256 generic reply to a generic request (REQUEST flag), and
1257 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1258 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1259 to define the payload for DATA flag. Added the flags to
1260 the implementation. Protocol TODO #9. Affected file is
1261 lib/silccore/silcchannel.h.
1263 Changed the client library to return the message length
1264 to application as well in the channel_message and private_message
1265 client operations. Affected files are
1266 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1267 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1268 and lib/silcclient/client_ops_example.c.
1270 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1271 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1272 the channel. Updated protocol specs and impelemented this
1273 to client and server. Protocol TODO #6. Affected files are
1274 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1275 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1277 Added new options m and M to CMODE command in Irssi SILC
1278 client to set these modes.
1280 * Deprecated all administrative commands from SILC protocol
1281 since they are highly implementation specific commands.
1282 Updated protocol specs. Moved the old commands in
1283 implementations to private range of command types. Affected
1284 files are silcd/command.c, lib/silcclient/command.c and
1285 lib/silcclient/command_reply.c. Protocol TODO #8.
1287 * Fixed a bug in server where sending unknown command crashes
1288 the server. Affected file silcd/command.c.
1290 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1292 * Added SILC_PROTOCOLVERSION macro to check protocol version
1293 of a socket connection. The affected file is
1294 lib/silcutil/silcsockconn.h.
1296 * Added better error logging in rekey protocol. Affected file
1299 * Do not check public key types in SKE during rekey. Affected
1300 file lib/silcske/payload.c.
1302 * Fixed the rekey protocol with PFS, which was totally broken.
1303 Affected file silcd/protocol.c.
1305 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1307 * Some client implementations quit network by doing first LEAVE
1308 and then immediately SIGNOFF (like Bombyx). We now do check
1309 after a short time after LEAVE notify and check whether the
1310 client is still valid after LEAVE, and if not we remove it from
1311 cache. Affected file is lib/silcclient/client_notify.c.
1313 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1315 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1316 it's good not to have security holes here.
1318 * Fixed a negative refcount situtuation for the config context.
1319 Affected file is silcd/serverconfig.c.
1321 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1323 * ROBOdoc documented lib/silcutil/silcutil.h.
1325 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1327 * Optimized even more the SilcPacketContext structure. Now
1328 totally saved 16 bytes of memory per context after optimization.
1329 Affected files are lib/silccore/silcpacket.[ch].
1331 * Made strict checks for valid SILC IDs. Affected file is
1332 lib/silccore/silcid.c.
1334 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1336 * Changed the object argument for silc_cipher_register,
1337 silc_hash_register, silc_hmac_register and silc_pkcs_register
1338 to const. Affected files are lib/silccrypt/silccipher.[ch],
1339 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1341 * Changed the silc_get_username and silc_get_real_name to
1342 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1344 * Fixed the Irssi SILC Client to use the silc_get_username and
1345 silc_get_real_name insted of glib routines since the glib
1346 routines only corrupt stack. Fixes the Irssi SILC to work in
1347 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1349 * Fixed the Irssi to not use g_get_home_dir since it crashes
1350 or returns garbage on cygwin and corrupts stack. Added function
1351 get_home_dir to Irssi routines. Affected files are
1352 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1354 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1356 * Made some structure optimizations. SFTP memory FS MemFSEntry
1357 entry structure. Optimized SilcTask structure. Optimized
1358 SilcPacketContext structure.
1360 Affected files lib/silcsftp/sftp_fs_memory.c,
1361 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1363 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1365 * And yet again reverted back the config thing since Johnny
1366 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1369 * Fixed memory leaks from config object. Affected files are
1370 silcd/serverconfig.[ch].
1372 * Added support for adding new connections to the server in rehash.
1373 After rehash they take effect.
1375 Added support for changing the maximum allowed connections in
1376 rehash. The number can grow but going smaller is not supported.
1378 Added function silc_server_num_sockets_by_remote to the
1379 silcd/server_util.[ch].
1381 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1383 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1385 * Added preliminary checking during config parsing for a valid
1386 public/private key and removed further checks in the code.
1387 Affected files are silcd/serverconfig.[ch], server.c.
1389 * Moved functions silc_server_drop() and silc_server_daemonise()
1390 from server.c to silcd.c since they are stricly related to
1391 the application activity.
1393 * Reverted a small part of the automatic ref/unref since
1394 it caused a double unref in some situations. Affected
1395 files are silcd/silcd.[ch], server.c, serverconfig.c.
1397 * Added some .cvsignore files in the lib directory.
1399 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1401 * Fixed silc_net_gethostbyaddr to correctly resolve by
1402 address. Affected file lib/silcutil/silcnet.c.
1404 * Fixed the notify relaying to client. The HMAC to be used
1405 with relayed packets ws wrong and caused decryption failure
1406 at the client end. Affected file is silcd/packet_receive.c.
1408 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1410 * Created new branch silc_protocol_1_0_branch.
1412 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1414 * Changed the silc_server_config_* routines to be SilcServer
1415 independent. They are now officially application specific code
1416 and not part of generic server implementation. Affected files
1417 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1419 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1421 * Added automatic referencing of config context in the
1422 silc_server_config_alloc, and automatic unreferencing in the
1423 silc_server_config_destroy. Affected files are
1424 silcd/serverconfig.[ch], silcd/silcd.c.
1426 * Fixed the silc_log_quick handling in the logging routines.
1427 It didn't log quickly when it was TRUE. Affected file is
1428 lib/silcutil/silclog.c. Also the flush delay was set even
1429 if it was 0 in config file. Affected file is
1430 silcd/serverconfig.c.
1432 * Added support for changing key pair of the server in rehash.
1433 Affected file silcd/server.c.
1435 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1437 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1438 too early, before getting the channel entry. Affected file
1439 is silcd/packet_receive.c.
1441 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1443 * Added functions silc_server_config_[ref/unref], these are used
1444 to prevent that the config object is destroyed.
1446 No longer directly affect global variables silc_log_quick and
1447 silc_log_delay, they are first cached inside the config object
1448 and then applied with silc_server_config_setlogfiles().
1450 silc_server_config_set_defaults() is now internal to
1451 serverconfig.c, there are no reasons to show this internal stuff
1454 Affected files are silcd/serverconfig.[ch].
1456 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1457 fprintf's to stderr, since some code may be executed again after
1458 the server went into the background. Affected files are
1461 * Added rehash support. Added function silc_server_rehash() that
1462 will perform all the basic tasks of the rehashing procedure.
1464 * Added command line option `-x, --hexdump'. This will enable the
1465 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1466 The option `--hexdump' implies `--debug'.
1468 * Fixed a bad bug in the logging APIs (silcutil library) where
1469 the application would crash after calling silc_log_reset_all().
1471 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1473 * Fixed the KICKED notify handling in client library to
1474 correctly remove the channel and all entries from the
1475 channel when I was kicked. This bug crashed the client.
1477 Fixed yet another but in KICKED notify handling to remove
1478 the kicked client correctly from the channel.
1480 Affected file is lib/silcclient/client_notify.c.
1482 * Fixed a minor bug in looking up correct client entry
1483 in KICKED notify in server. Affected file is
1484 silcd/packet_receive.c.
1486 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1487 sources correctly to distribution. Fixes --with-gmp option.
1489 * Removed the manual rehashing from ID Cache, and changed it
1490 to use the SILC Hash Table's auto rehash feature. Affected
1491 file is lib/silccore/silcidcache.c.
1493 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1495 * Fixed a bug in the silc_client_nickname_format function that
1496 handles the multiple same nickname formatting. Two clients
1497 with same nickname caused problems after the first one left
1498 and rejoined. It didn't format the nickname correctly.
1499 Affected file is lib/silcclient/idlist.c.
1501 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1503 * Don't change the topic if olod topic is same as new one.
1504 Affected file is silcd/packet_receive.c.
1506 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1508 * Added cross-reference support to the SILC Documentation
1509 generator. All types across all HTML files are now cross-
1510 referenced. Affected files util/robodoc/generator.c and
1511 scripts/silcdoc/silcdoc.
1513 * Added file lib/silcutil/silctypes.h to include all the
1514 arithmetic type definitions and some macros. Removed
1515 includes/bitmove.h and moved macros to silctypes.h.
1517 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1519 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1523 * Added `type' argument to silc_id_payload_parse_id function which
1524 now returns the type of the ID to the sent pointer. Affected
1525 file is lib/silccore/silcid.[ch].
1527 * Added check for CMODE_CHANGE notify type that mode change is
1528 allowed by the sender. Affected file silcd/packet_receive.c.
1530 * Added check for CUMODE_CHANGE notify type that mode change is
1531 allowed by the sender. Affected file silcd/packet_receive.c.
1532 Added the ID type as CUMODE_CHANGE notify type as argument
1533 to the `notify' client operation. Affected files are
1534 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1536 * Added function silc_client_add_server to the client library.
1537 Added support for resolving also channel and server info when
1538 received unknown entity in notify packet. Affected files are
1539 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1541 * Added function silc_command_get_status to return the command
1542 status from the command reply's argument payload. Affected files
1543 are lib/silccore/silccommand.[ch].
1545 * Added check for KICKED notify type that the kicking is
1546 allowed by the client. Affected file silcd/packet_receive.c.
1548 * Created function silc_get_input which can be used to get input
1549 (echo on or off) from user on command line. Affected files are
1550 lib/silcutil/silcutil.[ch].
1552 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1554 * Optimized silc_server_packet_relay_to_channel function.
1555 Added new function silc_channel_message_payload_encrypt which
1556 can be called directly if channel message payload needs to
1557 be encrypted and is already encoded (no need to call _encode
1558 function). Packet relaying is now done by router without any
1559 extra memory allocations. Affected files are
1560 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1561 silcd/packet_send.c.

1581 by the client. Affected files are silcd/server_util.[ch],
1582 silcd/packet_receive.c and silcd/command.c.
1584 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1587 ID length. It ignored that ID can be IPv6 based as well.
1588 Affected file lib/silccore/silcpacket.h.
1590 * Fixed the silc_id_id2str and silc_id_str2id to take the
1591 IPv6 address offset's into consideration. Affecte file is
1592 lib/silccore/silcid.c.
1594 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1596 * Fixed the internal Unix scheduler functions to check for
1597 NULL context they may receive. The affected file is
1598 lib/silcutil/unix/silcunixschedule.c.
1600 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1602 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1603 can specify different directory with --home command line
1604 parameter. Affected files irssi/src/silc/core/client_ops.c,
1607 * SILC-specific commands aren't now executed if the active server
1608 isn't of SILC-type, so there won't be problems with having
1609 IRC and SILC protocol support in same client. Affected files
1610 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1613 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1615 * Improved the signal support in SILC Schedule. Added new
1616 function silc_schedule_signal_call which is used by application
1617 to mark a signal to be called. It is now safe to perform
1618 any kind of tasks in signal callbacks since it is guaranteed
1619 that the application specified signal callback is called
1620 after the signal is over. Affected files are
1621 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1623 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Added `name' field to SilcChannelPrivateKey to represent
1626 application given name for the key. Moved also the context from
1627 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1628 Added the `name' argument also to the function
1629 silc_client_add_channel_private_key.
1631 Added function silc_client_current_channel_private_key to set the
1632 current channel private key in use.
1634 Added "change" command to KEY command which can be used to change
1635 the current channel private key. Bound the command also to
1636 alt+K (Alt+Shift+k).
1638 Also affected files lib/silcclient/client_channel.c,
1639 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1641 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1643 * Added silc_rng_get_byte_fast function in to the
1644 lib/silccrypt/silcrng.[ch].
1646 * Changed the interface of silc_packet_assemble and the
1647 silc_packet_send_prepare. If silc_packet_assmble is now
1648 called the application does not call silc_packet_send_prepare
1649 because the library will call it automatically. These
1650 interfaces now also return a reference to the outgoing buffer
1651 which includes the assembled packet, which the application can
1652 use to encrypt the packet.
1654 Affected files are lib/silccore/silcpacket.[ch],
1655 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1656 silcd/packet_send.c, server_backup.c and packet_receive.c.
1658 * Fixed a packet sending bug on very high load, where outgoing
1659 packet queue wasn't handled correctly and packets got corrupted.
1660 Affected files are lib/silcutil/*/silc*sockconn.c,
1661 lib/silcclient/client.c and silcd/server.c.
1663 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1665 * Added macro SILC_PACKET_DATALEN which can be used during
1666 packet assembling to check whether the data to be added to
1667 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1668 len is truncated until it fits it.
1670 Added checks for maximum length of channel message payload and
1671 private message payload also.
1673 Added checks for maximum packet length in server and in
1676 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1677 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1678 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1679 lib/silcclient/client_prvmsg.c.
1681 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1683 * Added silc_server_packet_queue_purge call to the
1684 silc_server_disconnect_remote to assure that all data in the
1685 queue before disconnecting is sent to the network. Affected
1686 file silcd/server.c.
1688 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1690 * Added the deleting of server's own ID cache entry to the
1691 silc_server_free function. Free also everything else that
1692 has been allocated in silc_server_init. The affected file
1695 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1697 * Added functions silc_parse_version_string, silc_version_to_num,
1698 and silc_ske_parse_version to parse SILC protocol style version
1699 strings. Affected files lib/silcutil/silcutil.[ch] and
1700 lib/silcske/silcske.[ch].
1702 * Added new configuration params: version_protocol, version_software
1703 and version_software_vendor to specify what version the remote
1704 host must at least be to be able to connect to server. The vendor
1705 string can be regex matched too. Added new function
1706 silc_server_connection_allowed to check maximum number of allowed
1707 connections, and allowed versions for incoming connections.
1708 Affected files are silcd/server.c, server_util.[ch] and
1711 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1713 * Added preliminary support for signals in scheduler. The
1714 signals we care about are now blocked always when the scheduler
1715 is locked. This way we can synchronise the use of signal with
1716 scheduler. It is guaranteed that when signal occurs the scheduler
1717 is not locked, and thus new tasks can be safely added to the
1720 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1721 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1722 Added new platform specific routines
1723 silc_schedule_internal_signals_[un]block and
1724 silc_schedule_internal_signal_[un]register.
1726 Added new functions to SILC Schedule API:
1727 silc_schedule_signal_[un]register. Each signal that application
1728 is going to use should be registered to the scheduler.
1730 Affected files are lib/silcutil/silcschedule.[ch],
1731 lib/silcutil/*/silc*schedule.c.
1733 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1735 * Check for unauthenticated client and server in the
1736 silc_server_new_client and silc_server_new_server functions.
1737 Affected file silcd/packet_receive.c.
1739 * Added function silc_string_is_ascii to check whether given
1740 string is 7-bit ASCII string. Affected files are
1741 lib/silcutil/silcutil.[ch].
1743 * Added function silc_id_is_valid_server_id into the
1744 silcd/serverid.c and added checking for valid Server ID's in
1745 silc_server_new_server. The Server ID must always be based
1746 on the server's public IP address.
1748 * Added logging of DISCONNECT packet message in the server.
1749 Affected file silcd/server.c.
1751 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1753 * Changed all library interfaces that use Global RNG to also
1754 accept SilcRng as argument. Affected files are
1755 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1756 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1757 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1758 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1759 lib/silccrypt/rsa.c.
1761 * Added function silc_pkcs_generate_key to the
1762 lib/silccrypt/silcpkcs.[ch] for applications so that they
1763 don't need to do pkcs->pkcs->init calls anymore.
1765 * Remove SilcSocketConnection from the SFTP API since it really
1766 wasn't needed there. The application has the information
1767 saved in its contexts anyway and the SFTP layer doesn't need
1768 know about it. Affected files lib/silcsft/silcsftp.h and
1769 lib/silcsftp/sftp_[server/client].c.
1771 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1772 The SilcSimContext is not SilcSim.
1774 * Fixed possible buffer overflows in silc_id_render in the
1775 lib/silcutil/silcutil.c.
1777 * On EPOC the global crypto module lists are not used at all
1778 in the crypto library. Added support for using the constant
1779 algorithm list on EPOC. Affected files are
1780 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1783 * Fixed the handling of third parameter of KICKED notify, since
1784 it was mistakenly updated to SILC Protocol 1.0 even though it
1785 is to be included in 1.1. Since it is not in 1.0 it is not
1786 mandatory, and this fix now handles it only if it is provided,
1787 and it is not error if it is not provided. Affected file
1788 lib/silcclient/client_notify.c.
1790 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1793 client. Affected file irssi/src/silc/core/client_ops.c.
1795 * Merged with Irssi 0.8.4 from irssi.org CVS.
1797 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1799 * Check for valid socket connection in client entries before
1800 sending any messages. Fixes a crash, but doesn't fix some
1801 other underlaying bug that is lurking there. Affected
1802 file silcd/packet_send.c.
1804 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1806 * $usermode, $cumode and $cumode_space expandos shouldn't do
1807 anything with non-SILC server records. Affected file
1808 irssi/src/silc/core/silc-expandos.c
1810 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1812 * Fixed the silc_net_check_[host/local]_by_sock to support
1813 IPv6 bound sockets as well. Now they can return IPv6 addresses
1814 as well. Affected file lib/silcutil/silcnet.c.
1816 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1817 Affected lib/silcutil/unix/silcunixnet.c.
1819 * Fixed ID rendering (at least on some platforms, not NetBSD)
1820 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1822 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1824 * Added silc_hash_public_key and silc_hash_public_key_compare
1825 functions to be used with SilcHashTable. They can be used to
1826 hash public keys and compare public keys in hash table. Affected
1827 file lib/silcutil/silcutil.[ch].
1829 * Added support for specifying multiple public keys for Client
1830 connection section in server configuration file. This makes it
1831 possible to accept multiple public keys from same host, or to
1832 make a section that accepts any incoming host, and have the
1833 accepted public keys listed in the section.
1835 Added functions silc_sever_[find/get]_public_key, added the
1836 support for this actually to all connection sections but only
1837 the Client section is currently allowed to specify multiple
1840 Affected files are silcd/server.c, server_internal.h,
1841 command.c, protocol.c, server_util.[ch], packet_receive.c.
1843 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1845 * Merged Irssi 0.8.2 from irssi.org CVS.
1847 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1849 * If silc_debug is TRUE, also output standard logging messages
1850 to stderr with the debug output.
1852 Made silc_log_reset_all() flushing all channels before returning.
1853 Also fixed some documentation typos.
1855 Affected files are lib/silcutil/silclog.[ch].
1857 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1859 * Fixed the server to check correctly the amount of connections
1860 from single host, by checking also the type of the connection.
1861 Fixed also the comparison of number of connections and number
1862 of allowed connections. Affected files are silcd/server.c,
1865 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1867 * Fixed the USERS command reply to save the user's mode on the
1868 channel as well. Fixed JOIN command reply to check whether a
1869 client is on channel already and not join it twice. Affected
1870 file lib/silcclient/command_reply.c.
1872 * Added new file silc-expandos.c into irssi/silc/core/ to return
1873 various stuff for various signal for the statusbar etc. updating.
1874 Now Irssi SILC client prints channel user modes etc. on the
1877 * The user mode (like server/router operator changes) is now shown
1878 on the Irssi SILC client's statusbar. The affected files are
1879 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1881 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1883 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1884 to SILC_SCHEDULE_[UN]LOCK macros.
1886 * Added more error printing to logs in server code. Affected
1887 files silcd/server.c and silcd/protocol.c.
1889 * Fixed -S option parsing in Irssi SILC Client. Affected file
1890 irssi/src/silc/core/silc-core.c.
1892 * Added silc_buffer_alloc_size function. Affected file is
1893 lib/silcutil/silcbuffer.h.
1895 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1897 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1898 constants. Affected files in
1899 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1902 * Changed the internal SFTP Memory FS table to const. Affected
1903 file lib/silcsftp/sftp_fs_memory.c.
1905 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1907 * Fixed the buffer formatting and unformatting routines to
1908 check the size of 64 bits types with sizeof(). Affected
1909 file is lib/silcutil/silcbuffmt.c.
1911 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1913 * Removed 0.6.x backwards support.
1915 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1917 * Changed all integer type names:
1918 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1919 to avoid collisions with other libraries using same type names
1922 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1924 * Added `prefer_ipv6' argument to the functions
1925 silc_net_gethostbyname[_async]. If it is TRUE it will return
1926 IPv6 address over IPv4. If FALSE IPv4 address is returned
1927 even if IPv6 address was found. Affected files
1928 lib/silcutil/silcnet.[ch].
1930 * Added support silc_net_create_connection[_async] to fallback
1931 to IPv4 address if IPv6 address could not be used (like if
1932 it doesn't work on a specific system). Affected file in
1933 lib/silcutil/unix/silcunixnet.c.
1935 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1937 * Added silc_schedule_reinit function to do the enlarging
1938 of the max tasks handling capabilities of the scheduler.
1939 Affected files lib/silcutil/silcschedule.[ch].
1941 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1943 * Added automatic extern "C" { ... } for C++ compilers so the
1944 application does not need to define them. Affected file
1945 includes/silcincludes.h.
1947 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1948 old name went against naming convention. Applications now
1949 include "silcclient.h" instead of "clientlibincludes.h".
1950 Removed includes/clientlibincludes.h, it is redundant now.
1952 * Renamed includes/version.h to silcversion.h.
1954 * Added really preliminary support for OS/2 into the util
1955 library. Only thread & mutex API is implemented, others
1956 are still to be implemented. Created the lib/silcutil/os2/
1957 directory. Created also file includes/silcos2.h.
1959 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1961 * Added preliminary BeOS support into the util library.
1962 Created lib/silcutil/beos/, and implemented all the needed
1963 functions to support SILC on BeOS. Created also file
1964 includes/silcbeos.h.
1966 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1968 * Added proper initializations to silc's irssi code, so it's
1969 now possible to load it as module. Affected files
1970 irssi/src/silc/core/silc-core.c,
1971 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1973 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1975 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1978 * Fixed the silcdoc document generator to correct generate
1979 docs from all kinds of filenames. Affected files are
1980 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1982 * ROBOdoc documented lib/silcutil/silcmemory.h.
1983 Added also new function silc_memdup.
1985 * Removed lib/silcutil/silcbufutil.h and moved those routines
1986 to the lib/silcutil/silcbuffer.h.
1988 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1990 * Added `user_count' to the SilcChannelEntry which now tells the
1991 number of users on the channel. The user count is now saved
1992 in normal server of global channels as well. Affected files
1993 silcd/server.c, idlist.h, packet_receive.c and command.c.
1995 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1996 include file utility functions.
1998 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1999 instead of calling directly OS routines.
2001 * Fixed NICK change printing in Irssi SILC Client. Fixed
2002 KICKED notify printing in Irssi SILC Client. Affected file
2003 irssi/src/silc/core/client_ops.c.
2005 * Fixed a NICK change bug in client library, to not recreate the
2006 client_entry->channels hash table everytime nick is changed.
2007 Affected file lib/silcclient/client.c.
2009 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2011 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2012 the SKE interface a bit.
2014 * Fixed padding problem in PKCS#1. The padding was not actually
2015 random since the random number generator was used incorrectly.
2016 This security bug affects only when encrypting with PKCS#1, and
2017 it is not currently used at all in SILC. SILC only use signing
2018 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2020 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2022 * Rewrote the notify handling in Irssi SILC client to not call
2023 the events as signals. Fixes problems with Perl support.
2024 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
2026 * Send the auto-nicking NICK command in client library with
2027 little timeout after connecting. The affected file is
2028 lib/silcclient/client.c.
2030 * Added following new config file settings:
2031 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
2032 key_exchange_timeout, conn_auth_timeout, connections_max,
2035 Implemented all the new config settings handling in the server.
2037 Optimized the use of SKE Mutual flag usage. Use it only
2038 if connection authentication protocol is not based in public
2041 Renamed all SilcServerConfigSection* to SilcServerConfig*
2042 to have a bit shorter names.
2044 Affected files silcd/serverconfig.[ch], server.[ch], and
2047 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2049 * Cleaned up the listening sockets code, preparing for the rehash
2050 support. Affected file is silcd/server.c.
2052 * Fixed some output messages. Affected files are silcd/silcd.c,
2055 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2057 * Create lib/doc/silcrng_intro.html document as introduction
2058 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2060 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2062 * Fixes to the silcd config template. Affected file is
2063 doc/example_silcd.conf.in.
2065 * Removed type casts from silc_calloc(), conforming to the
2066 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2068 * Removed param_name member from client, server, and router
2069 section structs, now identifying the param directly.
2071 Added CONFIG_FREE_AUTH macro in config file parsing.
2073 Affected files are silcd/serverconfig.[ch].
2075 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2077 * Fixed command line parameter handling. All SILC initialization
2078 is now done in silc_core_init() which also fixes autoconnecting
2081 Affected files irssi/src/silc/core/silc-core.c,
2082 irssi/src/fe-text/silc.c.
2084 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2086 * Added new configuration options and blocks:
2087 keepalive_secs, reconnect_count, reconnect_interval,
2088 reconnect_interval_max, reconnect_keep_trying and
2089 require_reverser_lookup. Added ConnectionParam block, and
2090 implemented the connection parameters when connecting as
2091 initiator and when accepting connections as responder.
2093 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2094 whether given configuration value has been given already.
2096 Affected files silcd/serverconfig.[c], server.[c].
2098 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2099 algorithm parts and created new file silcalgs.conf, that
2100 is now included from the example_silcd.conf.in.
2102 * Optimized the silc_server_connect_to_router_second to take
2103 the connection configuration object from the SilcServerConnection
2104 object instead of finding it during the connecting phase.
2105 Added the configuration object to SilcServerConnection struct.
2106 Affected files silcd/server_internal.h, server.c.
2108 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2110 * Add the client on channel after it was resolved at the
2111 channel message receiving, and it was not already on the
2112 channel. Affected file lib/silcclient/client_channel.c.
2114 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2116 * Fixed the public key authentication to allocate always the
2117 destination signature buffer instead of using static buffer.

2122 * Unified the serverconfig.[ch]'s helper function interface.
2123 Affected file silcd/serverconfig.[ch].
2125 * Removed doc/example_silc.conf.in since it is redundant.
2126 The make install will now install irssi/silc.conf file.
2128 * Added new Passphrase and Publickey authentication methods to
2129 config file, allowing both public key and passphrase based
2130 authentication to be set at the same time.
2132 Added `prefer_passphrase_auth' setting in config file which
2133 can be used to set to prefer passwd auth if both passwd and
2134 public key is set. If not set, public key is preferred.
2135 This has effect only when being initiator (responder will try
2138 Added support for authentication with passphrase and public key
2139 at the same time. The passphrase is tried first always since
2140 it is faster to check.
2142 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2144 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2146 * Merged the new SILC Config library, with the server parsing
2147 support. Read the header file silcconfig.h or the toolkit
2148 documentation for the news. Affected files are
2149 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]

2157 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2159 * The silc_cipher_register, silc_hash_register and
2160 silc_hmac_register now checks if the object to be registered
2161 is registered already. Affected files are
2162 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2164 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2170 * Allow zero length channel messages inside the Channel Message
2171 Payload. Affected file lib/silccore/silcchannel.c.
2173 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2174 as header filenames.
2176 * Removed lib/silcclient/README and created HTML file
2177 lib/silcclient/silcclient_using.html, which is now included
2178 as part of Toolkit documentation.
2180 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2182 * Fixed CUMODE_CHANGE notify handling to change the mode of
2183 correct client. Affected file lib/silcclient/client_notify.c.
2185 * Make silc_rng_alloc fail if it cannot allocate the sha1
2186 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2188 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2190 * Fixed the file transfer's key agreement payload to include
2191 zero port also if the hostname is NULL because it could not
2194 Call file transfer monitor callback now also if error occurs
2195 during key agreement protocol.
2197 Changed the silc_client_file_send interface to return the
2198 SilcClientFileError instead of session id. The session ID
2199 is returned into pointer provided as argument.
2201 Check that the file exists locally before sending the
2202 file transfer request at all.
2204 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2206 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2207 error than can occur while key agreement protocol. Affected
2208 file lib/silcclient/silcapi.h.
2210 * Fixed the event_mode CMODE handler to not crash when mode
2211 is changed and +k mode is set in the channel. Affected file
2212 irssi/src/silc/core/silc-channels.c.
2214 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2215 SILC_LOG_WARNING to give out Warning and not Error. Affected
2216 file lib/silcutil/silclog.c.
2218 * Fixed the channel message payload decryption in the function
2219 silc_channel_message_payload_decrypt to not modify the original
2220 buffer before it is verified that the message decrypted
2221 correctly. Otherwise, next time it is called with correct
2222 channel key it won't encrypt since the payload is corrupted.
2223 Affected file lib/silccore/silcchannel.c.
2225 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2227 * Do not constantly resize the window. A fix patch by cras.

2233 Affected file lib/silcutil/silcnet.c.
2235 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2237 * Fixed a bug in hash table internal routine for traversing
2238 the table with foreach callback. The current entry may
2239 become invalid in the callback but it was referenced after
2240 the callback returned.
2242 Do not allow auto rehashing of hash table during the
2243 silc_hash_table_foreach operation, for same reasons as it is
2244 not allowed for SilcHashTableList. Affected files are
2245 lib/silcutil/silchashtable.[ch].
2247 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2249 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2250 Win32 DLL. extern's in header files are now declared with
2253 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2255 * Fixed private message handling. It used some old code that
2256 caused the client to crash. Affecte file is
2257 lib/silcclient/client_prvmsg.c.
2259 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2261 * Added function silc_client_add_channel,
2262 silc_client_replace_channel_id, and removed functions
2263 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2264 from client library.
2266 * Added cross reference of the joined channels to the
2267 SilcClientEntry, and changed the SilcChannelEntry's
2268 users list to SilcHashTable. The affected files are
2269 lib/silcclient/idlist.[ch].
2271 * Fixed a bug in hash table tarversing. While the hash table
2272 is traversed with SilcHashTableList the table must not be
2273 rehashed. It is now guaranteed that auto rehashable tables
2274 are not rehashed while tarversing the list. Also defined that
2275 silc_hash_table_rehash must not be called while tarversing
2276 the table. Added function silc_hash_table_list_reset that must
2277 be called after the tarversing is over. The affected files are
2278 lib/silcutil/silchashtable.[ch].
2280 * Changed all hash table traversing to call the new
2281 silc_hash_table_list_reset in server and in client library.
2283 * Added function silc_client_on_channel to return the
2284 SilcChannelUser entry if the specified client entry is joined
2285 on the specified channel. This is exported to application as
2286 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2288 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2290 * Fixed founder regaining problem with JOIN command on normal
2291 server. The notify for mode change must be sent always and
2292 not only if !cmd->pending. Affected file silcd/command.c.
2294 * Fixed the WHOWAS command's reply sending to support the
2295 lists correctly. Affected file silcd/command.c.
2297 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2299 * When sending JOIN command to router for processing the
2300 sender's old command identifier was not saved back to the
2301 sender's command context, fixed now. The affected file is
2304 * Create the key in JOIN command of the router did not return
2305 the channel key, added check for this. Affected file is
2308 * Fixed a channel ID update bug in JOIN command reply. Do
2309 not directly upgrade the ID but call the function
2310 silc_idlist_replace_channel_id if the ID was changed.
2311 Affected file silcd/command_reply.c.
2313 * Fixed memory leaks from command calling if it would fail.
2314 Affected file silcd/command.c.
2316 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2318 * Applied patches from cras:
2320 Memory leak fixes around libaries, irssi window resize fix,
2321 new silclist.h and silcdlist.h, all extern inline changed to
2324 * Removed dotconf from lib/dotconf, not needed anymore.
2326 * Removed TRQ from lib/trq, not needed anymore.
2328 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2329 with server connections. Later this will be configurable
2330 in config file after new config file is done. Affected file
2333 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2335 * Fixed a crash in server related to channel announcements.
2336 Affected file silcd/server.c.
2338 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2340 * Fixed memory leaks in silc_server_create_new_channel*
2341 functions. Affected file silcd/server.c.
2343 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2344 which ID was changed. This way the router will send the
2345 user list for the channel again, and server won't be in
2346 desync in some rare circumstances. Affected file is
2347 silcd/packet_receive.c.
2349 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2351 * Check for NULL socket pointer in the function
2352 silc_server_packet_send_to_channel_real. Affected file
2353 silcd/packet_send.c.

2356 list. Affected file silcd/packet_receive.c.
2358 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed some header addition to Toolkit distribution in
2361 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2363 * Added lib/silcclient/client_ops_example.h as an template
2364 file for application programmers to quickly start using
2365 the SilcClientOperation functions in their application.
2366 Updated the lib/silcclient/README as well to tell about this
2367 nice file made available.
2369 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2371 * Call silc_server_remove_from_channels when removing client
2372 entry when NO_SUCH_CLIENT_ID was received. Affected file
2373 is silcd/command_reply.c.
2375 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2377 * Added server & router operator statistics updating. Affected
2378 file silcd/packet_receive.c and silcd/command.c.
2380 * Fixed the SERVER_SIGNOFF notify handling on normal server
2381 not to save the history information for clients. Same was
2382 fixed earlier in remove_clients_by_server function, but not
2383 here. Affected file silcd/packet_receive.c.
2385 * Raised the default connection-retry count from 4 to 7 in
2386 server. Affected file silcd/server.h.
2388 * Cancel any possible reconnect timeouts when we start the
2389 key exchange. Affected file silcd/server.c.
2391 * Do not reconnect on connection failure when SCONNECT was
2392 given. Affected files silcd/server.[ch].
2394 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2396 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2398 * Fixed the NICK command to always give the unformatted
2399 nickname to the one giving the NICK command. If unformatted
2400 nickname is cached already it will be formatted and the
2401 local entry will always get the unformatted nickname.
2402 Affected file lib/silcclient/idlist.c.
2404 * Fixed some double frees from client library commands.
2405 Affected file is lib/silcclient/command.c.
2407 * Fixed CUMODE command in server to assure that no one can
2408 change founder's mode than the founder itself, there was a
2409 little bug. Affected file silcd/command.c.
2411 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2413 * Removed the SilcClientCommandDestructor from the client
2414 libary, it is not needed anymore. Affected files are
2415 lib/silcclient/silcapi.h, command[_reply].[ch],
2416 client_notify, idlist.c.
2418 * Fixed GETKEY command to first resolve client, and then
2419 resolve the server only if the client was not found, instead
2420 of resolving both at the same time. Affected file is
2421 lib/silcclient/command.c.
2423 * Added silc_client_start_key_exchange_cb and lookup the
2424 remote hostname and IP address before starting the key
2425 exchange with server. The affected file is
2426 lib/silcclient/client.c.
2428 * The server's public key is now saved using the IP address
2429 of the server and not the servername for the filename.
2430 The hostname public key filename is checked as an fall back
2431 method if the IP address based filename is not found.
2433 Fixed the GETKEY command to save the fetched server key
2434 in correct filename.
2436 Print the remote server's hostname now when new key is
2437 received during connection process. Affected file is
2438 irssi/src/silc/core/client_ops.c.
2440 * Return always our own public key to the client if it asks
2441 for it with GETKEY command. Affected file silcd/command.c.
2443 * Removed the use_auto_addr variable from default config
2444 file since it was in wrong section. Affected file is
2447 * Fixed TOPIC_CHANGE notification to not route it when it
2448 was sent using silc_server_send_notify_to_channel function.
2449 Affected file silcd/command.c.
2451 * Fixed silc_server_send_notify_kicked to send the kicker's
2452 Client ID also, it was missing. Affected files are
2453 silcd/command.c, silcd/packet_send.[ch].
2455 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2457 * Do not save client history information in SERVER_SIGNOFF.
2458 Fixes the bug in normal server that it does not detect
2459 the client becoming valid after the server becomes back
2460 online. Affected file silcd/server_util.c.
2462 * Added `sock_error' field into the SilcSocketConnection
2463 context. When error occurs during socket operation (read
2464 or write) the error is saved. Added also new function
2465 silc_socket_get_error to return human readable socket error
2466 message. Affected files are lib/silcutil/silcsockconn.[ch],
2467 lib/silcutil/unix/silcunixsockconn.c, and
2468 lib/silcutil/win32/silcwin32sockconn.c.
2470 * The server now prints the socket error message in the
2471 signoff for client. Affected file silcd/server.c.
2473 * Fixed the `created' channel information sending from router
2474 to server in JOIN command. Checks now whether the channel
2475 really was created or not and set it according that.
2477 Fixed the JOIN command to use the client entry's current
2478 ID during the joining procedure instead of the one it sent
2479 in the command (it is checked though), since it can change
2480 between the packet processing and command processing, and
2481 would just case unnecessary pain in the client end. Affected
2482 file silcd/command.c.
2484 * Fixed a channel key payload sending to use correct channel
2485 ID when the server was forced to change the channel's ID by
2486 router. Router sent the key payload with the old Channel ID.
2487 Affected file silcd/packet_receive.c.
2489 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2491 * Call silc_server_save_channel_key only if the key payload
2492 was provided in the JOIN command's command reply. Affected
2493 file silcd/command_reply.c.
2495 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2497 * Fixed silc_mp_sizeinbase to return the value correctly with
2498 MPI. Affected file lib/silcmath/mp_mpi.c.
2500 * Fixed the stop_server signal to correctly stop the scheduler
2501 and gracefully stop the server when SIGTERM or SIGINT signals
2502 are received. Affected file silcd/silcd.c.
2504 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2506 * Simple handling of TERM and HUP signals. Also added some log
2507 flushing call around. Affected file is
2510 * Fixed small bugs in silclog.c. Now buffering output will take
2511 effect after 10 seconds since startup: This will ensure that
2512 no important startup messages are lost. Also output redirection
2513 will preserve original format ([Date] [Type] message).
2514 Affected file is lib/silcutil/silclog.c.
2516 * Added two options to the config file, in the logging section:
2517 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2518 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2520 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2522 * Do not print the warning about log files not being initialized
2523 more than once to avoid excess logging. Affected file is
2524 lib/silcutil/silclog.c.
2526 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2527 the SIM copying in make install in Makefile.am.pre.
2529 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2531 * Rewritten silclog APIs. Globally interesting changes follows:
2532 silc_log_set_files() changed to silc_log_set_file().
2533 silc_log_set_callbacks() changed to silc_log_set_callback().
2534 ROBOdoc documented silclog header file.
2535 SilcLogCb now returns bool to wether inihibit the default
2536 handler or not (to keep the old behaviour return always TRUE).
2537 The new APIs should also fix the problem of the
2538 silcd_error.log file that was written in the current directory.
2541 Log files streams will remain opened after silc_log_set_file()
2542 call, means less CPU usage notably on high traffic servers.
2543 File streams are now full buffered, and flushed to the disk
2544 every 5 minutes, lesses HD activity and CPU usage.
2545 Messages can be redirected, allowing admins to configure
2546 one single logfile for all server messages.
2547 the silc_log_quick global variable to activate fast-logging.
2548 Affected files lib/silcutil/silclog.[ch]
2550 * Changed some code to conform new silclog APIs. Affected
2551 files are doc/example_silcd.conf.in, silcd/server.c
2552 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2555 * Fixed a memory leak that could occur in some situations.
2556 Affected file silcd/serverconfig.c.
2558 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2560 * Added the silc_client_del_client to remove the client from
2561 all channels as well. Affected file lib/silcclient/idlist.c.
2563 * Fixed the client library to correctly remove the client
2564 from all channels when the client entry is being destroyed.
2565 Affected file lib/silcclient/client_notify.c, command.c.
2567 * Added auto-nicking support to the client library. If the
2568 applicatio now sets client->nickname it will be sent to the
2569 server after connecting by the library. This way for example
2570 SILCNICK (or IRCNICK) environment variables will have effect
2571 and always change the nickname automatically to whatever
2572 it is wanted. Affected file lib/silcclient/client.[ch].
2574 * Renamed silc_server_command_bad_chars to the
2575 silc_server_name_bad_chars and moved it to the
2576 silcd/server_util.[ch]. Added also new function
2577 silc_server_name_modify_bad to return nickname that
2578 includes bad characters as new nickname without those
2579 bad characters. This check and modify is now used in
2580 silc_server_new_client when the username is initially set
2581 as nickname, so it must be checked to be valid nickname.
2582 Affected file silcd/packet_receive.c.
2584 * The nickname length is now taken from the packet for real
2585 and not trusted to strlen() since it clearly can return
2586 wrong length for nickname including bad characters. This
2587 also applies to channel names. Affected file silcd/command.c.
2589 * Removed the lib/silcsilm/modules directory. Modules are now
2590 compiled into the lib/silcsim. Fixed the copying of the
2591 modules to follow symbolic links in Makefile.am.pre.
2593 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2595 * Fixed silc_string_regexify list creation. Fixes bugs with
2596 BAN and INVITE commands in server. The affected file is
2597 lib/silcutil/unix/silcunixutil.c.
2599 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Removed the command destructor entirely from the server's
2602 command and command reply routines. It is not needed, and
2603 its usage was buggy and caused crashes. Affected files are
2604 silcd/command[_reply].[ch].
2606 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Cancel protocol and NULL sock->protocol if timeout
2609 occurred during protocol. Affected file silcd/server.c.
2611 * Cancel protocol timeouts always before calling the final
2612 callback, to assure that after final callback is called
2613 no other state will be called for the protocol anymore.
2614 Affected file silcd/protocol.c.
2616 * Print error log if incoming connection configuration could
2617 not be found. Affected file silcd/server.c.
2619 * Fixed JOIN command to correctly save the founder mode
2620 to the client on normal SILC server, when the channel
2621 was created by the router. Affected file silcd/command.c.
2623 * Fixed LIST command (hopefully) to send correct reply
2624 packets. Affected file silcd/command.c.
2626 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * The silc_packet_receive_process now returns FALSE if the
2629 read data was invalid packet, and TRUE if it was ok.
2631 The server now checks that if unauthenticated connection
2632 sends data and its processing fails the server will close
2633 the connection since it could be a malicious flooder.
2635 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2637 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Make sure the warning about error opening a log file is
2640 printed only once and not everytime it fails (produces
2641 too much useless log). Affected file lib/silcutil/silclog.c.
2643 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2645 * Made the silc_server_daemonise() function more readable.
2646 Affected file silcd/server.c.
2648 * Pid file is now optional, the user may comment it out from
2649 the config file. Removed define SILC_SERVER_PID_FILE, we
2650 don't need a default any longer. Affected file
2651 configure.in.pre, lib/Makefile.am.pre.
2653 * Make some use of the pid file. The server now dies at startup
2654 if it detects a valid pid file on his path. The server would
2655 die anyway in this circumstance, because of the bind() failure.
2656 Affected file silcd/silcd.c.
2658 * No longer compiling lib/dotconf.
2660 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Fixed JOIN command parsing not to crash. Affected file
2663 lib/silcclient/command.c.
2665 * Fied the NICK_CHANGE notify to add the new client entry
2666 even it is resolved. This removes an <[unknown]> nick
2667 thingy bug in the client. Affected file is
2668 lib/silcclient/client_notify.c.
2670 * Do not try to allocate 0 bytes (efence does not like it)
2671 in lib/silccore/silccomand.c when encoding payload.
2673 * Do not take IRCNICK as nickname in Irssi SILC client since
2674 it is not possible to set nickname before hand connecting
2675 the server (TODO has an entry about adding auto-nicking
2678 * Changed the silc_server_command_pending to check whether
2679 there already exists an pending entry with the specified
2680 command, command identifier and pending callback. This is
2681 to fix IDENTIFY and WHOIS related crashes that may register
2682 multiple pending commands with same identifier. Affected
2683 file silcd/command.c.
2685 * Fixed the server to reconnect to the router even if it
2686 was already reconnecting and EOF was received. This to
2687 fix a possibility that the server wouldn't ever try to
2688 auto-reconnect to the router. Affected file silcd/server.c.
2690 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Fixed the server's password authentication to use the
2693 length of the locally saved password, and not the one
2694 sent in the packet. Affected file silcd/protocol.c.
2696 * Fixed same password authentication problem in the
2697 Authentication Payload handling routines in
2698 lib/silccore/silcauth.c.
2700 * Yet another password authentication problem fixed with
2701 channel password handling in silcd/command.c.
2703 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2705 * If first character of string in silc_parse_userfqdn is '@'
2706 then do not parse it. Affected file is
2707 lib/silcutil/silcutil.c.
2709 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Fixed minor bug in IDENTIFY command reply sending, which
2712 caused various weird problems during JOIN when it was
2713 resolving names for users. Affected file silcd/command.c.
2715 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Fixed the IDENTIFY command reply sending to chech better valid
2718 clients. It was possible to send incomplete list of replies.
2719 Affected file silcd/command.c.
2721 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Added silc_client_command[s]_[un]register functions now to
2724 dynamically register the commands in client library. Removed
2725 the static table of commands. This allows the client library
2726 to call commands without causing the application to know about
2727 what commands library has called.
2729 Removed the INFO command reply kludge to detect when the command
2730 was called by library. Now library use its own command reply
2731 function for INFO command.
2733 Added function silc_client_command_call to call a command.
2734 Application can use it to call command, not access the structure
2737 Now all commands that are sent by the client library (not
2738 explicitly sent by application) use own command reply functions.
2740 Affected files around lib/silcclient/ and in
2741 irssi/src/silc/core/.
2743 * Fixed the WHOIS command reply sending to chech better valid
2744 clients. It was possible to send incomplete list of replies.
2746 Fixed the WHOIS and IDENTIFY to send the request to router
2747 if normal server did not do it and did not find any results.
2749 Affected file silcd/command.c.
2751 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Moved the internal data from SilcClient context into its
2754 own file, not accesible to application. Affected files
2755 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2756 and other files in client library.
2758 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2760 * Added doc/examples installation target in Makefile.am.pre.
2763 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2766 commands the found client entry will be removed from the
2767 cache, after notifying application about the error. Affected
2768 file lib/silcclient/command_reply.c.
2770 * Changed the /MSG to check for exact nickname user gave, and
2771 not let `nick' match `nick@host' if it is only one found. Now,
2772 user must type the exact nickname (like nick@host2) even if
2773 there are no more than one same nicks found. This is to avoid
2774 a possibility of sending nickname to wrong nickname since
2775 `nick' could match `nick@host'. Affected file is
2776 irssi/src/core/silc-servers.c.
2778 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Do not print "you are now server operator" or similar when
2781 giving /away command. Affected files are
2782 irssi/src/silc/core/client_ops.c, silc-servers.h.
2784 * Made the silc_server_command_pending_error_check to send
2785 the same command reply payload it received back to the
2786 original sender of the command. This way all arguments
2787 that was received by the server will be received by the
2788 client too. Affected file silcd/command.c.
2790 * Added the silc_idcache_add to return the created cache entry
2791 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2793 * Add global clients to expire if they are not on any channel.
2794 This is because normal server will never know if they signoff
2795 if they are not on any channel. The cache expiry will take
2796 case of these entries. This is done by normal servers only.
2797 The affected files are silcd/command_reply.c,
2798 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2800 * If server receives invalid ID notification for WHOIS or
2801 IDENTIFY and the ID exists in the lists, it is removed.
2802 Affected file silcd/command_reply.c.
2804 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2805 in client then client entry that it matches is searched and
2806 the nickname is printed on the screen for user. Affected
2807 file irssi/src/silc/core/client_ops.c.
2809 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * Use cache entry expire time in the LIST command reply to
2812 purge old entries from the cache after the LIST command
2813 reply has been received. This way we don't have non-existent
2814 entries in the cache for too long. Affected file is
2815 silcd/command_reply.c.
2817 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * If we are normal server, and we've not resolved client info
2820 in WHOIS or IDENTIFY from router, and it is global client,
2821 we'll check whether it is on some channel. If it is not
2822 then we cannot be sure about its validity and will resolve it
2823 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2824 file silcd/command.c.
2826 * Search channel by name (if possible) rather than by ID
2827 in IDENTIFY command's command reply. Affected file is
2828 silcd/command_reply.c.
2830 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2832 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2833 Updated specs and implemented it. Affected file silcd/command.c,
2834 silcd/packet_send.c and silcd/packet_receive.c.
2836 * Implemented the <founder auth> payload handling in the JOIN
2837 command. If provided all conditions for channel joining
2838 except requirement to provide correct passphrase can be
2839 overrided by the channel founder. Updated the protocol specs.
2840 Affected file silcd/command.c.
2842 Added support for founder auth in JOIN command in client
2843 library. Fixed the parsing of the JOIN command now to support
2844 all options as they should be. The affected file is
2845 lib/silcclient/command.c.
2847 * Optimized the WHOIS and IDENTIFY commands to send the request
2848 to router only if it includes nicknames or other names. If
2849 they include only IDs then check the local cache first before
2850 routing. Affected file is silcd/command.c.
2852 * Added channels topic announcements. Affected file is
2853 silcd/packet_receive.c and silcd/server.c.
2855 * Fixed the silc_server_send_notify_topic_set to really destine
2856 the packet to channel. Affected file silcd/packet_send.c.
2858 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2859 library. Affected file lib/silcclient/client_notify.c.
2861 * Added UMODE announcements. Affected file silcd/server.c.
2863 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Memory leak fixes in:
2867 lib/silcutil/silcsockconn.c
2868 lib/silcske/silcske.c
2869 lib/silcske/groups.c
2871 lib/silccrypt/silcpkcs.c
2872 lib/silccore/silccommand.c
2873 lib/silccore/silcidcache.c
2878 * ROBOdoc documented the lib/silcske/groups.h file and a
2879 bit changed the interface for better.
2881 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2883 * Update the client entry context in the ID cache after
2884 nick change. Affected file lib/silcclient/command.c.
2885 Fixes the CUMODE command when regaining founder privileges,
2886 and a little WHOIS problem.
2888 * Fixed silc_net_gethostbyname to correctly call the
2889 inet_ntop. Affected file lib/silcutil/silcnet.c.
2891 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2893 * Added IPv6 support checking to the configure.in.pre, added
2894 also --enable-ipv6 option to override the check. Affected
2895 file configure.in.pre.
2897 * The silc_thread_create now calls the start function
2898 directly if threads support is not compiled in. Removes
2899 ugly #ifdef's from generic code. Affected files are
2900 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2902 * Added silc_net_gethostby[name/addr]_async to asynchronously
2903 resolve. Affected files are lib/silcutil/silcnet.[ch].
2905 * Added support for rendering IPv6 based server, client and
2906 channel IDs. Affected file lib/silcutil/silcutil.c.
2908 * Added support for creating IPv6 based server IDs. Affected
2909 file is silcd/serverid.c.
2911 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2913 * Added silc_net_gethostby[addr/name] into the
2914 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2915 routines. Added silc_net_is_ip[4/6]. Affected file is
2916 lib/silcutil/unix/silcunixnet.c. All routines that take
2917 address as argument now supports both IPv4 and IPv6 addresses.
2919 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2921 * Fixed LIST command reply sending in server. Affected file
2924 * Server now sends the kicker's client ID in the KICK notify
2925 to the kicked client. Affected file silcd/command.c.
2927 * The client library now parses the kickers client ID and
2928 UI displays it. Affected files lib/silcclient/client_notify.c
2929 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2931 * Made all payload parsing function prototypes consistent.
2932 They all take now const unsigned char * and uint32 pair as
2933 the payload data instead of SilcBuffer. Changes all around
2934 the source tree. Other unsigned char* -> const unsigned char*
2935 changes around the tree as well.
2937 * Optimized SFTP client and server packet sending not to
2938 allocate new buffer for each packet but to recycle the
2939 first allocated buffer. Affected files are
2940 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2942 * Optimized the SFTP client to use SilcList instead of
2943 SilcDList for requests, because it is faster. Affected file
2944 is lib/silcsftp/sftp_client.c.
2946 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2947 into lib/silccore/silcid.[ch].
2949 Renamed silcpayload.[ch] into silcargument.[ch].
2951 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * If client entry is deleted with active key agreement
2954 session, abort the session.
2956 The silc_client_abort_key_agreement now calls the completion
2957 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2959 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2962 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Don't use __restrict in older GCC's. Affected file is
2965 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2967 * silc_net_localhost now attempts to reverse lookup the
2968 IP/hostname. Affected file lib/silcutil/silcnet.c.
2970 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2971 command. It can be used to gain founder privileges at
2972 the same time when joining the channel.
2974 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2975 kicker's client ID as well. Updated protocol specs.
2977 Defined that the server must send SILC_COMMAND_IDENTIFY
2978 command reply with error status to client who sent
2979 private message with invalid client ID.
2981 Updated the protocol specification.
2983 * Added silc_server_send_command_reply to send any
2984 command reply. Affected file silcd/packet_send.[ch].
2986 * Added silc_id_payload_encode_data to encode ID payload
2987 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2989 * The server now send IDENTIFY command reply with error
2990 status if client ID in private message is invalid. Affected
2991 file silcd/packet_receive.c.
2993 * Save the server key file with server's IP address in
2994 the filename instead of hostname. The affected file is
2995 irssi/src/silc/core/client_ops.c.
2997 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3002 * Added libtool support for compiling shared objects in
3003 lib/silcsim. Affected file configure.in.pre and
3004 lib/silcsim/Makefile.am. Original patch by cras.
3006 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Pid file configuration, and server's config file fixes
3009 patch by toma. Updated CREDITS file.
3011 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Fixed silc_client_channel_message to not try to decrypt
3014 the message twice if it resolved the destination client
3015 information. This could cause of dropping one channel
3016 message. Affected file lib/silcclient/client_channel.c.
3018 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3021 lib/silcclient/client.c. This function is used when the SILC
3022 Client is run under some other scheduler, or event loop or
3023 main loop. On GUI applications, for example this may be
3024 desired to used to run the client under the GUI application's
3025 main loop. Typically the GUI application would register an
3026 idle task that calls this function multiple times in a second
3027 to quickly process the SILC specific data.
3029 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3031 * Fixed silc_server_drop() for dropping the supplementary
3032 groups as well, this could cause a security hole on some
3035 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

3041 to run server on foreground. A patch by debolaz.
3042 Affected files silcd/server.c, silcd/silcd.c.
3044 * Fixed MOTD to return the MOTD file server name. Affected
3045 file silcd/command.c.
3047 * Added INFO command reply handling to the Irssi SILC Client.
3048 Affected file irssi/src/silc/core/client_ops.c.
3050 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Fixed the silc_idcache_list_* routines to really support
3053 the dynamic list. Fixes a crash. Affected file is
3054 lib/silccore/silcidcache.c.
3056 * Fixed the LIST command reply to really call LIST command's
3057 pending callbacks. Affected file silcd/command_reply.c.
3059 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Update conn->local_entry->nickname after giving NICK
3062 command. Affected file lib/silcclient/command.c.
3064 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3066 * Added the [pid] option to the silcd configuration file
3068 Affected files: serverconfig.[ch] and silcd.c
3070 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Save fingerprint in WHOIS command reply in server.
3073 Affected file silcd/command_reply.c.
3075 * Fixed NICK commands pending callback registration.
3076 Affected file lib/silcclient/command.c.
3078 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Use ++server->cmd_ident when sending commands in server,
3081 instead of random number. Affected file silcd/command.c.
3083 * Fixed GETKEY command reply to call actually GETKEY pending
3084 command callbacks. Affected file silcd/command_reply.c.
3086 * A bit stricter check for nicknames. Check for same nickname
3087 in NICK command also. Affected file silcd/command.c.
3089 * Do not call INFO command everytime client ID changes, only
3090 during first connecting. Affected file lib/silcclient/client.c.
3092 * Set the new nickname only after successful command reply for
3093 NICK command is returned by server. Affected file
3094 lib/silcclient/command.c.
3096 * Remove nicknames from nicklist during server_signoff notify.
3097 Should fix /NAMES bit more. The affected file is
3098 irssi/src/silc/core/silc-channels.c.
3100 * Added `fingerprint' field to the SilcIDListData in the
3101 silcd/idlist.h to hold the fingerprint of the client's
3104 Send the fingerprint of the client's public key in WHOIS
3107 Affected files silcd/command.c, and silcd/idlist.[ch].
3109 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3110 create fingerprint from given data.
3112 * Show the fingerprint of the client's public key in WHOIS.
3113 Affected files irssi/src/module-formats.[ch] and
3114 irssi/src/silc/core/client_ops.c.
3116 * Format the multiple same nicknames also during JOIN and
3117 NICK_CHANGE notifys. Affected file is
3118 lib/silcclient/client_notify.c.
3120 * Do not print error on screen for invalid private message
3121 payload since it can come if someone is sending private
3122 messages with wrong key. Affected file
3123 lib/silccore/silcprivate.c.
3125 * Fixed multiple concurrent /PING crash. Affected file
3126 lib/silcclient/command.c.
3128 * Changed the wrong ID encoding. All IP addresses must be
3129 in MSB first order in encoded format. They were encoded
3130 wrong and was in LSB format. Affected files are
3131 silcd/serverid.c, lib/silcutil/silcutil.c.
3133 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3135 * Call the `connect' client operation through the scheduler
3136 in case of error. Affected file lib/silcclient/client.c.
3138 * Call the `failure' client operation even if the error
3139 occurred locally during a protocol. Affected file is
3140 lib/silcclient/protocol.c.
3142 * Added support of sending LIST command to router from normal
3143 server. This way normal server can get list of all channels
3144 in the network too. Fixed the channel list sending in the
3145 server too. Affected files are silcd/command.c, and
3146 silcd/command_reply.[ch].
3148 * Added silc_server_update_channels_by_server and
3149 silc_server_remove_channels_by_server. They are used during
3150 disconnection of primary router and in backup router protocol.
3151 Affected file silcd/server_util.[ch], silcd/server.c and
3152 silcd/server_backup.c.
3154 * Fixed channel adding to global list in IDENTIFY command
3155 reply in server. Affected file silcd/command_reply.c.
3157 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * If the incoming packet type is REKEY or REKEY_DONE process
3160 that packet always synchronously. Fixes yet another MAC
3161 failed error on slow (dialup) connections. Affected file
3162 lib/silcclient/client.c and silcd/server.c.
3164 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Call check_version SKE callback for initiator too. Affected
3167 file lib/silcske/silcske.c.
3169 * Implemented fix for security hole found in the SKE that was
3170 fixed in the specification few days back; the initiator's
3171 public key is now added to the HASH value computation.
3172 Added backwards support for the old way of doing it too, for
3173 old clients and old servers. Affected file is
3174 lib/silcske/silcske.c.
3176 * Enabled mutual authentication by default in SKE. If initiator
3177 is not providing mutual authentication the responder will
3178 force it. This will provide the proof of posession of the
3179 private key for responder. The affected files are
3180 lib/silcclient/protocol.c and silcd/protocol.c.
3182 * Do not cache anymore the server's public key during SKE.
3183 We do mutual authentication so the proof of posession of
3184 private key is done, and if the server is authenticated in
3185 conn auth protocol with public key we must have the public
3186 key already. Affected file silcd/protocol.c.
3188 * Added new global debug variable: silc_debug_hexdump. If
3189 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3190 file lib/silcutil/silclog.[ch].
3192 * Fixed compilation warning due to char * -> const char *.
3193 Affected files lib/silcutil/silcnet.h, and
3194 lib/silccore/silcauth.[ch].
3196 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3198 * Fixed CMODE command when new channel key was created. If
3199 the creation failed the old key was removed. Next time giving
3200 same command would crash the server since the old key was
3201 freed already. Affected file silcd/command.c.
3203 * Fixed the silc_server_announce_get_channels to not crash
3204 on reconnect. Affected file silcd/server.c.
3206 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Added silc_log_set_debug_string function to set a regex
3209 string to match for debug output. Only the function names,
3210 or filenames matching the given debug string is actually
3211 printed. This way it is possible to filter out those debug
3212 strings that user is not interested in.
3214 Fixed a bug in silc_string_regexify.
3216 Affected files lib/silcutil/silclog.[ch], and
3217 lib/silcutil/unix/silcunixutil.c.
3219 * Changed the -d options in both server and Irssi SILC client
3220 to take the debug string as argument. Affected files
3221 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3223 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3225 * Added silc_hash_babbleprint to create a Bubble Babble
3226 Encoded fingerprint. The encoding is developed by Antti
3227 Huima (draft-huima-babble-01.txt), and it creates human
3228 readable strings out of binary data. Affected file
3229 lib/silccrypt/silchash.[ch].
3231 * Print the babble print now in addition of fingerprint as well
3232 in Irssi SILC client. Affected files are
3233 irssi/src/fe-common/silc/module-formats.[ch],
3234 irssi/src/fe-common/silc/core/client_ops.c.
3236 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Fixed a security problem found in SKE. The initiator's
3239 public key too is now added to the HASH hash value creation
3240 which is signed by the responder to create the SIGN value.
3241 This will prevent anyone in the middle to lie to the responder
3242 about the initiator's public key. If this is done now, the
3243 man in the middle will get caught. Updated the protocol
3246 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Better installation directory handling. Configure module
3249 paths and other paths automatically to example_silc* files
3250 in doc/. A patch by toma.
3252 * Fixed compiler warning from MPI library, and from SILC RNG.
3255 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3256 It can be configured with ./configure. A patch by toma.
3258 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3260 * Find correct make to use in prepare-clean. A patch by
3261 toma. Affected file prepare-clean.
3263 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3265 * Added irssi variables use_auto_addr, auto_bind_ip,
3266 auto_bind_port and auto_public_ip.
3268 * Changed the interface for silc_client_send_key_agreement
3269 in lib/silcclient/silcapi.h
3273 irssi/src/silc/core/silc-core.c
3275 lib/silcclient/silcapi.h
3276 irssi/src/silc/core/silc-channels.c
3277 lib/silcclient/client_keyagr.c
3280 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Added silc_pkcs_public_key_compare to compare two
3283 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3285 * Check that the client who set the founder mode on the
3286 channel is the same client that is giving the founder
3287 mode to itself. It is done by comparing the saved public
3288 key (it is saved even in the authentication is passphrase).
3289 Affected file silcd/command.c.
3291 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Do not process packet for disconnected socket connection.
3294 Affected file lib/silccore/silcpacket.c.
3296 * Process the DISCONNECT packet through scheduler in the
3297 client library. Affected file lib/silcclient/client.c.
3299 * Fixed the silc_client_packet_parse to not to increase
3300 the packet sequence number if the conn->sock and the
3301 current socket connection is not same. This can happen
3302 for example during key agreement when the conn includes
3303 multiple socket connections (listeners). Affected file
3304 lib/silcclient/client.c.
3306 * The sender of the file transfer request now provides also
3307 the pointer (listener) for the key exchange protocol. If
3308 the listener cannot be created then it sends empty key
3309 agreement and lets the receiver provide the listener.
3311 Added `local_ip' and `local_port' arguments to the
3312 silc_client_file_send. If they are provided they are used,
3313 if not then it will attempt to find local IP address, if
3314 not found or bind fails then the remote client will provide
3317 Affected files are lib/silcclient/client_ftp.c and
3318 lib/silcclient/silcapi.h.
3320 * Extended the FILE SEND command to support defining the
3321 local IP and port for key exchange listener. They are
3322 optional. Affected file irssi/src/silc/core/silc-servers.c.
3324 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3326 * Defined to WHOIS command reply the sending of fingerprint
3327 of the client's public key (if the proof of posession of the
3328 corresponding private key is verified by the server).
3329 Updated to the protocol specification.
3331 * Added support of receiving the client's public key's
3332 fingerprint in command reply in client library. Affected
3333 file is lib/silcclient/command_reply.c, and
3334 lib/silcclient/idlist.[ch].
3336 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Do not send over 128 chars long nickname to the server
3339 in NICK command. Affected file lib/silcclient/command.c.
3341 * Do not send over 256 chars long channel names to the server
3342 in JOIN command. Affected file lib/silcclient/command.c.
3344 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Assure that silc_server_close_connection cannot be called
3347 twice for same socket context. Affected file is
3350 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Send error message to application if opening file for
3353 writing during file transfer fails. Affected file is
3354 lib/silcclient/client_ftp.c.
3356 Remove all file transfer sessions for a client that we're
3357 removing from ID cache.
3359 Affected file is lib/silcclient/client_ftp.c.
3361 * Fixed silc_net_addr2bin to return correct address. Affected
3362 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3364 * Fixed file transfer session removing on signoff notify.
3365 Affected file irssi/src/silc/core/silc-servers.c.
3367 * Added the SilcClientFileError to be returned in the monitor
3368 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3369 Affected file lib/silcclient/silcapi.h.
3371 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3373 * Fixed a crash in silc_client_ftp_free_sessions and
3374 silc_client_ftp_session_free_client. Affected file
3375 lib/silcclient/client_ftp.c.
3377 * Added `disabled' field in the SilcChannelEntry in the server
3378 to indicate if the server entry is disabled. Affected file
3379 silcd/idlist.h, silcd/command[_reply].c.
3381 * SILC server adds now /var/run/silcd.pid everytime it is
3382 started. Affected file silcd/silcd.c.

3388 * Fixed a crash in client resolving in client_prvmsg.c in
3389 client library. Affected file lib/silcclient/client_prvmsg.c.
3391 * Do not actually remove the client directly from ID cache
3392 during SERVER_SIGNOFF, but invalidate it. This way we
3393 preserve the WHOWAS info for the client. Affected file
3394 silcd/server_util.c.
3396 * Fixed SERVER_SIGNOFF notify handling in the server. The
3397 server is now able to process incoming SERVER_SIGNOFF notify
3398 for a server that it doesn't even know about. It will remove
3399 the clients provided in the notify. Affected file
3400 silcd/packet_receive.c.
3402 * Check for partial packet in data queue after every packet that
3403 was found from the queue. Return and wait for more data if
3404 there is partial data in queue. Affected file is
3405 lib/silccore/silcpacket.c.
3407 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * Added SilcClietFileError enum to indicate error in
3410 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3411 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3412 Affected files lib/silcclient/silcapi.h and
3413 lib/silcclient/client_ftp.c.
3415 * Check that newsize in silc_buffer_realloc is larger than
3416 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3418 * Added better monitor of file transfers. It now monitors
3419 key agreement protocol during the file transfer too. Added
3420 error reporting too. Affected files
3421 irssi/src/silc/core/silc-servers.c,
3422 irssi/src/fe-common/silc/module-formats.[ch].
3424 * Wrote a help file for FILE command.
3426 * Added silc_rng_global_get_byte_fast to get not-so-secure
3427 random data as fast as possible. Random data is read from
3428 /dev/urandom if available and from the SILC RNG if not
3429 available. It is used in padding generation. Affected file
3430 lib/silccrypt/silcrng.[ch].
3432 * All packets in client library are now processed synchronously.
3433 Optimized packet processing a lot. Affected file
3434 lib/silcclient/client.c.
3436 * All server connection packets are processing synchronously
3437 now in server, to optimize packet processing. Affected file
3440 * Include files are installed now only in Toolkit distribution
3441 if make install is given. Affected files: all Makefile.am's.
3443 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Assure that silc_client_notify_by_server_resolve does not
3446 resolve the client information multiple times. If it cannot
3447 be found by the first it cannot be found at all. Affected
3448 file lib/silcclient/client_notify.c.
3450 * Fixed WHOWAS command reply calling. Affected file
3451 lib/silcclient/command_reply.c.
3453 * Removed all references to silc_idlist_get_client from the
3454 Irssi SILC client since that call is internal call used by
3455 the library. The Irssi SILC client will use now client
3456 retrieval functions found in silcapi.h.
3458 * Fixed a bug in resolving nickname info before sending
3459 private message. It used freed memory. Affected file
3460 irssi/src/silc/core/silc-servers.c.
3462 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Assure my_channels statistics cannot go negative in server.
3465 Affected files silcd/server.c, silcd/server_util.c.
3467 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3469 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3471 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

3477 lib/sftp/sftp_fs_memory.c.
3479 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Added silc_net_localip to return local host's IP address.
3482 Affected file lib/silcutil/silcnet.[ch].
3484 * If key exchange or rekey protocol is active for a connection
3485 parse all packets syncronously since there might be packets
3486 in packet queue that we are not able to process without first
3487 processing packets before them. Affected file silcd/server,
3488 lib/silcclient/client.c.
3490 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3491 whether library should continue processing the packet.
3492 Affected file lib/silccore/silcpacket.h.
3494 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3495 SilcSFTPMonitorData to SFTP server to monitor various
3496 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
3497 lib/silcsftp/sftp_server.c.
3499 * Added silc_file_size to return file size. Affected file
3500 lib/silcutil/silcutil.[ch].
3502 * Implemented the file transfer support for the client library.
3503 Added preliminary support for simple client to client one-file
3504 transmission. Affected file lib/silcclient/client_ftp.c,
3505 lib/silccilent/client.[ch].
3507 * Added new local command FILE to the Irssi SILC Client.
3508 It is used to perform the file transfer. It has subcommands
3509 SEND, RECEIVE, SHOW and CLOSE. Affected files
3510 irssi/src/silc/core/client_ops.c,
3511 irssi/src/silc/core/silc-server.[ch].

3520 * Renamed silc_file_read and silc_file_write to functions
3521 silc_file_readfile and silc_file_writefile. Added function
3522 silc_file_open and silc_file_close. Affected files
3523 lib/silcutil/silcutil.[ch].
3525 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Resolve the client info when received private message or
3528 channel message for a client which nickname we don't know.
3529 Affected files lib/silcclient/client_prvmsg.c and
3530 lib/silcclient/client_channel.c.
3532 * Do not crash in /KEY if client is not connected. Affected
3533 file irssi/src/silc/core/silc-channels.c.
3535 * Added SilcClientStatus field to the SilcClientEntry in the
3536 lib/silcclient/idlist.h.
3538 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3539 is incomplete and is being resolved, it won't be resolved
3542 Make sure also that USERS command reply does not resolve
3543 twice information. Affected file is
3544 lib/silcclient/command_reply.c.
3546 Make sure that silc_client_get_clients_by_list does not
3547 resolve twice same information.
3549 * Check for valid client->id in the silc_server_free_client_data.
3550 Affected file silcd/server.c.
3552 * Fixed /GETKEY nick@server not to crash if the server entry
3553 is not found. Affected file lib/silcclient/command.c.
3555 * Fixed the silc_server_check_cmode_rights to check the
3556 requested modes correctly. Affected file silcd/command.c.
3558 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3560 * Better checks for non-printable chars in nick added.
3561 Affected file silcd/command.c.
3563 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Call the silc_server_udpate_servers_by_server in the
3566 primary router that comes back online in the backup resuming
3567 protocol. Otherwise it routes packets wrong. Affected file
3568 silcd/server_util.[ch], silcd/server_backup.c.
3570 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3573 lib/silcutil/silcbuffmt.[ch].
3575 * Redefined the SILC packet header to include the padding
3576 length. Affected file lib/silccore/silcpacket.[ch].
3578 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3579 length for maximum padding up to 128 bytes). Affected
3580 file lib/silccore/silcpacket.h.
3582 * Removed all backwards support for old 0.5.x MAC thingies.
3583 The SILC packet header change makes it impossible to be
3584 backwards compatible.
3586 * Send the ENDING packet with timeout in the backup resuming
3587 protocol. This is to assure that all routers has connected
3588 to the primary router. Affected file silcd/server_backup.c.
3590 * Changed the RNG to take the first IV from random data. It
3591 used to take it from zero actually. Changed the RNG also
3592 to use /dev/urandom during session. /dev/random is used
3593 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3595 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Changed the SILC packet header to have the first two bytes
3598 (the packet length) encrypted. Affected files aroung the
3599 code tree, lib/silccore/silcpacket.[ch]. Removed the
3600 SilcPacketCheckDecrypt callback. It is not needed anymore
3601 since the silc_packet_receive_process will determine now
3602 whether the packet is normal or special.
3604 * Implemented the unidirectional MAC keys. Affected files
3605 lib/silcske/silcske.c, silcd/protocol.c and
3606 lib/silcclient/protocol.c.
3608 * Implemented the packet sequence number to the MAC computation.
3609 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3610 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3611 lib/silcclient/protocol.c.
3613 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Allow backup router to announce servers. All servers
3616 announced by backup router are added to the global list
3617 automatically. Update hte server's socket to our primary
3618 router also when backup router announces a server.
3619 Affected file silcd/packet_receive.c.
3621 * Do not update the client->router in the function
3622 silc_server_udpate_clients_by_server if the client is on
3623 global list. We might fail to find any specific server
3624 for locally connected clients and local cell clients. They
3625 should still use the `from' and not `to' as client->router.
3626 This fixes backup router resuming protocol. Affected file
3627 silcd/server_util.c.
3629 * Decrease channel statistics count only if the channel
3630 deletion worked. Affected files are silcd/server.c and
3631 silcd/server_util.c.
3633 * Added silc_server_update_servers_by_server to update origin
3634 of all server entries. Used during backup router protocol.
3635 Affected files silcd/server_util.[ch], silcd/server.c. and
3636 silcd/backup_router.c.
3638 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3639 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3640 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3641 lib/silccrypt/silchmac.c.
3643 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3645 * Assure that router cannot reroute the same channel message
3646 to the sender. Affected file silcd/packet_receive.c.
3648 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3650 * Made better checks that the channel message is not sent
3651 to the router it came from. Affected file is
3652 silcd/packet_send.c. Fixed memory leak too.
3654 * Announce informations for incoming router connection, but
3655 only after checking if it is replaced by backup router.
3656 Affected file silcd/packet_receive.c.
3658 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3660 * Fixed the backup resuming protocol to work in multiple
3661 router environment. Affected file silcd/server_backup.c.
3663 * Route packet only to one router in the function
3664 silc_server_packet_send_to_channel. Affected file is
3665 silcd/packet_send.c.
3667 * Fixed silc_server_send_notify_dest to set the broadcast
3668 flag. Fixed the silc_server_send_notify_topic to actually
3669 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3670 Affected file silcd/packet_send.c.
3672 * Changed the SFTP Filesystem interface. Changed the
3673 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3674 the filesystem operation function. The SilcSFTPFilesystem
3675 is now a context that is allocated by all filesystem allocation
3676 functions and it already includes the operations structure
3677 and filesystem specific context. It is given as argument
3678 now to the silc_sftp_server_start. This made the interface
3679 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3680 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3682 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3684 * Changed the backup router adding and getting interfaces
3685 in the server. The router that will be replaced by the
3686 specified backup router is now sent as argument. Affected
3687 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3690 * Added silc_net_addr2bin_ne to return the binary form of
3691 the IP address in network byte order. Affected files
3692 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3694 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * Check for existing server ID in silc_server_new_server
3697 and in silc_server_connect_to_router_final and remove the
3698 old entry if it exists. Affected file silcd/packet_receive.c,
3701 * Send the channel message always to only one router, either
3702 in upstream or downstream. Affected file is
3703 silcd/packet_send.c.
3705 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * Wrote the definition of the backup resuming protocol to the
3708 protocol specification.
3710 * Removed one redundant channel key generation from normal
3711 server during joining procedure. Removed one redundant
3712 channel key sending from server to router during joining
3713 procedure. Affected file silcd/command.c.
3715 * Made minor bugfixes to the backup router resuming protocol.
3716 Affected file silcd/server_backup.c, server.c.
3718 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Added --disable-asm configuration option. Affected files
3721 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3724 * Implemented the backup resuming protocol that is used to
3725 resume the primary router position in the cell after the
3726 primary router comes back online. Affected files
3727 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3728 and silcd/server_util.[ch].
3730 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3732 * Sleep two (2) seconds after sending QUIT command to server.
3733 Affected file lib/silcclient/command.c.
3735 * Assure that if outgoing data buffer is pending do not force
3736 send any data. Affected file silcd/packet_send.c.
3738 * Assure that if outgoing data buffer is pending do not force
3739 send any data. Affected file lib/silcclient/client.c.
3741 * Implemented the backup router support when the primary router
3742 goes down. The servers and routers can now use the backup
3743 router as new primary router without loosing connectivity.
3745 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3748 in the server to indicate disabled entry. All data read
3749 from the connection will be ignored and no data is sent
3750 for entry that is disabled. Affected files are
3751 silcd/idlist.h, silcd/server.c.
3753 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3755 * Created SFTP client and server test programs in the
3756 lib/silcsftp/tests directory.
3758 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3760 * Implemented memory filesystem (virtual filesystem) for
3761 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3764 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3766 * Implemented the SFTP (SSH File Transfer Protocol) to the
3767 lib/silcsftp. It includes SFTP client and SFTP server
3770 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3772 * Moved lib/silccore/silcprotocol.[ch] to the
3773 lib/silcutil library.
3775 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3776 take variable argument list pointer as argument. Affected
3777 file lib/silcutil/silcbuffmt.[ch].
3779 * Added silc_buffer_set function that is used to set data
3780 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3781 Affected file lib/silcutil/silcbuffer.h.
3783 * Changed various routines in the core library to use the new
3784 silc_buffer_set instead of allocating new buffer only for
3787 * Added 64-bit value formatting and unformatting support to the
3788 silc_buffer_[un]format routines. Affected file is
3789 lib/silcutil/silcbuffmt.[ch].
3791 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3792 to includes/bitmove.h.
3794 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3796 * Fixed channel user mode saving in client library. Affected
3797 file lib/silcclient/command[_reply].c.
3799 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Defined the file transfer to the SILC Protocol. Added
3802 new packet type SILC_PACKET_FTP and defined File Transfer
3803 Payload. The mandatory file transfer protocol is SFTP
3804 (SSH File Transfer Protocol). Affected file in addition
3805 of the internet draft is lib/silccore/silcpacket.h.
3807 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3808 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3809 is used as part of backup router protocol when the primary
3810 router of the cell is back online and wishes to resume
3811 the position as primary router.
3813 * Redefined the MAC generation keys in the protocol. The
3814 same key is not used anymore in both direction. Both
3815 direction will now use different keys for sending and
3816 receiving. This fixes a potential security flaw. This
3817 change causes incompatibilities in the protocol.
3819 * Redefined also the MAC computation from the packet.
3820 An packet sequence number is now added to the MAC
3821 computation. This prevents possible replay attacks against
3822 the protocol. This change too causes incompatibilities
3825 Added `sequence' field to the SilcPacketContext to hold
3826 the current sequence number for the packet.
3828 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * Added `created' field to the SilcIDListData in the file
3831 silcd/idlist.h to indicate the time when the entry was
3834 * Added `created' field to the SilcChannelEntry too. Affected
3835 file silcd/idlist.h.
3837 * Added `creation_time' aguments to all the announcement functions
3838 in the server. If it is provided then only the entries that
3839 was created after the provided time frame are actually
3840 announced. Affected file silcd/server.[ch].
3842 * The protocol says that the Channel ID's IP address must be
3843 based on the router's IP address. Added check for this in
3844 the silc_server_new_channel when processing incoming New Channel
3845 Payload. Affected file silcd/packet_receive.c.
3847 * Print out the correct version with --version in SILC client.
3848 Affected file irssi/src/silc/core/silc-core.c.
3850 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3852 * Fixed WHOWAS command to check for completnes of the client
3853 entry always, not just when the command is coming from client.
3854 Affected file silcd/command.c.
3856 * Added new function silc_server_packet_queue_purge to purge the
3857 outgoing data queue to the network. After the function returns
3858 it is guaranteed that the outgoing packet queue is empty.
3859 Affected file silcd/packet_send.[ch].
3861 * Purge the outgoing packet queue in the rekey protocol's final
3862 callback to assure that all rekey packets go to the network
3863 before quitting the protocol. Affected file silcd/server.c.
3865 * Added silc_client_packet_queue_parse as similar function as
3866 in server to the client library. The affected file is
3867 lib/silcclient/client.c.
3869 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Splitted silcd/server.c and created silcd/server_util.[ch]
3872 for utility functions.
3874 * Added new socket flag SILC_SF_DISABLED to indicate that the
3875 connection is open but nothing can be sent to or received from
3876 the connection. Affected file lib/silcutil/silsockconn.[ch].
3877 The checking for disabled socket is checked in the low level
3878 silc_socket_write and silc_socket_read functions.
3880 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3882 * Allow only nicknames and channel names that fits into the
3883 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3885 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3887 * When processing JOIN command reply in server check that if
3888 the channel exists in our global list we'll move it the local
3889 list. Affected file silcd/command_reply.c.
3891 * Fixed the check whether client is joined on the channel already
3892 in JOIN command. Affected file lib/silcclient/command.c.
3894 * Fixed the JOIN command reply to check whether the channel
3895 already exists. Affected file lib/silcclient/command_reply.c.
3897 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3899 * Added silc_ske_status_string to map the SKE error numbers
3900 to readable strings. The affected files are
3901 lib/silcske/silcske[_status].[ch].
3903 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3905 * Do not show the private channels on the WHOIS channel list
3906 as it is not allowed by the protocol. The affected file is
3909 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3911 * Assure that the packet length digged from the actual packet
3912 is something sensible in the silc_packet_decrypt_rest_special
3913 in lib/silccrypt/silcpacket.c.
3915 * Free and NULL the allocated pointer in silc_hmac_alloc if
3916 the HMAC allocation fails. The affected file is
3917 lib/silccrypt/silchmac.c.
3919 * Print the selected security properties to the log files in
3920 the server. Affected file silcd/protocol.c.
3922 * Add SKE's reference counter even if calling the completion
3923 callback manually. Otherwise it goes negative, although it
3924 does not cause any problems. The affected file is
3925 lib/silcske/silcske.c.
3927 * Remove the client entry with short timeout after giving the
3928 KILL command. Affected file lib/silcclient/command.c.
3930 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3931 case all found clients are already disconnected (WHOWAS would
3932 found them) in the server. Affected file silcd/command.c.
3934 * Update the last_receive (time of last data received) to be
3935 updated only when received private or channel message so that
3936 the idle time showed in WHOIS makes more sense.
3938 * Added boolean field `valid' in to the SilcClientEntry in the
3939 client library to indicate whether the entry is valid or not.
3940 This fixes the nickname change bug on channel when changing
3941 the nickname to be same than the old (like nick to Nick) the
3942 nickname formatter doesn't set the new nick anymore to Nick@host.
3943 Affected file lib/silcclient/idlist.[ch].
3945 * Now actually fixed the nickname changing on disconnection.
3946 Added new function silc_change_nick to the Irssi SILC Client.
3947 Affected file irssi/src/silc/core/client_ops.c,
3948 irssi/src/silc/core/silc-nicklist.[ch].
3950 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Check that the public key exists in the GETKEY command before
3953 trying to encode it. Affected file silcd/command.c.
3955 * Print some notifications on received public keys with GETKEY
3956 command in the Irssi SILC Client. Affected files are
3957 irssi/src/fe-common/silc/module-formats.[ch],
3958 irssi/src/silc/core/client_ops.c.
3960 * Use IDENTIFY command to resolve the server information in the
3961 GETKEY command instead of INFO command. Affected file
3962 lib/silcclient/command.c.
3964 * All command reply functions in the client library now calls
3965 the pending command reply callbacks even if an error has
3966 occurred. The server has done this a long time and now it was
3967 time to move the client library to this as well. Now all
3968 errors can be delivered back to the pending command reply
3969 callbacks if necessary. Affected files are
3970 lib/silcclient/command[_reply].[ch].
3972 * Change the nickname on disconnection back to the username
3973 because in reconnect the server will enforce it to it anyway.
3974 Affected file irssi/src/silc/core/silc-servers.c.
3976 * Fixed a config file parsing bug in the Irssi SILC client.
3977 Affected file irssi/src/silc/core/clientconfig.c.
3979 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3981 * When printing the channel mode on JOIN, verify that the
3982 channel key and channel's HMAC are valid. Affected file
3983 irssi/src/silc/core/client_ops.c.
3985 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3987 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3988 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3989 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3991 * Removed channel key rekey task deleting from the function
3992 silc_server_save_channel_key. Affected file silcd/server.c.
3993 Added explicit timeout task context instead that is used to
3994 delete the task if we are registering a new task before the
3995 new task has elapsed.
3997 * When channel key rekey occurs the client library now saves
3998 the old channel key for a short period of time (10 seconds) and
3999 is able to use it in case some is still sending channel
4000 messages encrypted with the old key after the rekey. Affected
4001 file lib/silcclient/[idlist.h|client_channel.c].
4003 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Added check to the silc_server_new_id_real to not accept
4006 new ID if it is the sender's own ID. Affected file is
4007 silcd/packet_receive.c.
4009 * Assure that we do not announce ourself or the one we've
4010 sending our announcements when we're router and are announcing
4011 servers to our primary router. Affected file silcd/server.c.
4013 * Fixed silc_server_command_identify_check_client to assemble
4014 correct WHOIS packet. It send corrupted WHOIS packet and
4015 caused problem with router to router connections. Affected
4016 file silcd/command.c.
4018 Fixed also silc_server_command_whois_check the same way
4019 as for the IDENTIFY command.
4021 * Added new SilcIDListStatus to the server in the SilcIDListData
4022 structure. The status now includes the current status of
4023 the entry (like registered, resolved etc.). Affected file
4024 silcd/idlist.[ch]. Defined a bunch of different status types
4025 as well. This replaced the old boolean registered field as well.
4027 Added resolve_cmd_ident field to the SilcClientEntry structure
4028 too so that if the entry is for example being resolved so
4029 another command may attach to the same pending command reply
4030 without requiring to resolve the same entry again. This concept
4031 should optimize the WHOIS and the IDENTIFY resolving under
4032 heavy load by taking away unnecessary resolving for entries
4033 that are being resolved already.
4035 Added support for adding multiple pending commands for one
4036 command idenfier. Affected file silcd/command[_reply].[ch].
4038 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4039 before deleting the data. Otherwise the hash table will have
4040 freed data in comparison functions. Affected file is
4041 silcd/command_reply.c.
4043 * Fixed silc_idlist_replace_client_id to add the new entry to
4044 the cache with NULL nickname. Otherwise there will be invalid
4045 memory as the nickname after the nickname is freed. Affected
4046 file silcd/packet_receive.c.
4048 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4049 saved into wrong slots because the previous number of entries
4050 was not taken into account. Affected file silcd/idlist.c.
4051 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4053 * If we are router and we receive JOIN notify to a channel that
4054 does not have any users then notified client is marked as the
4055 channel founder, as it is it. The affected file is
4056 silcd/packet_receive.c
4058 * Added to the extended hash table API's table_del_*ext functions
4059 the destructor as argument too, so that the caller can decide
4060 which destructor to use or whether to use destructor at all.
4061 Affected file lib/silcutil/silchashtable.[ch].
4063 * Fixed ID Cache purging. It actually deleted the entries from
4064 the hash table after the data was freed. The hash table ended
4065 up comparing freed memory. The affected file is
4066 lib/silccore/silcidcache.c.
4068 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Fixed Irssi SILC client's KILL command's HELP syntax.
4072 * The USERS command now resolves the detailed user information
4073 if the userinfo field is missing. Affected file is
4074 lib/silcclient/command_reply.c.
4076 * Do not print error in silc_file_read if the read file does
4077 not exist. Just silently return NULL. Affected file is
4078 lib/silcutil/silcutil.c.
4080 * Fixed the silc_log_output to not wine about NULL filename
4081 and to not create some bogus " " filename. Affected file is
4082 lib/silcutil/silclog.c.
4084 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4086 * Fixed various printing bugs on the user interface in the
4087 Irssi SILC Client. Minor changes that were forgotten from
4090 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4092 * Fixed the configure.in.pre and the compilation and distribution
4093 environment to support the new autoconf 2.52. That version is
4094 now required to compile the CVS trunk.
4096 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4098 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4099 to generally parse user@fqdn format strings. Affected file
4100 lib/silcutil/silcutil.c.
4102 * Added nickname_format and nickname_force_format fields to the
4103 SilcClientParams structure. The first one defines the format
4104 for the nicknames that the library will enforce if the receives
4105 multiple same nicknames. The second one is boolean value and
4106 can be used to force the library to always enforce the format
4107 to the nicknames regardles whether there are multiple nicknames
4108 or not. This configurable formatting was employed to flexibly
4109 support accessing multiple nicknames from the user interface.
4110 The userinterface can now set the nicknames to what ever format
4111 they prefer. Affected file lib/silcclient/silcapi.h.
4113 Added function silc_client_nickname_format to the file
4114 lib/silcclient/idlist.c. It performs the nickname formatting.
4116 Added new field `hostname´ to the SilcClientEntry context.
4117 It holds the hostname of the client. Affected file is
4118 lib/silcclient/idlist.h.
4120 * Irssi SILC Client sets the nicknames in nick@hostn format.
4121 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4122 irssi/src/silc/core/silc-core.c.
4124 The WHOIS printing now also shows both the real nickname and
4125 the formatted nickname so that user knows how to access the
4126 user if there are multiple same nicknames cached. Affected
4127 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4128 printing formatting too to take the hostname now as a separate
4129 argument. The Affected file is
4130 irssi/src/fe-common/silc/modules-formats.[ch].
4132 * Changed the silc_client_get_clients_local to accept the formatted
4133 nickname as argument. It accepts the real nickname too but the
4134 formatted nickname can be used to find the true entry from
4135 multiple entries. Affected file lib/silcclient/silcapi.h and
4136 lib/silcclient/idlist.c.
4138 * Added nickname_format_parse field to the SilcClientParams.
4139 It is a callback function provided by the application to parse
4140 the nickname out of the formatted nickname string. The library
4141 calls it to get the nickname from the formatted string. Since
4142 the application generally knows better the format of the nickname
4143 string it parses it instead of the library, even though library
4144 encodes the formatted string. If the callback function is not
4145 provided then the library will use the string as is. The
4146 affected file is lib/silcclient/silcapi.h.
4148 * All the nickname strings passed to the client library in
4149 commands are now expected to be formatted nickname strings.
4150 If the command does not support the formatted nickname string
4151 it will assume that the sent string is the actual nickname.
4152 Affected file lib/silcclient/command.c.
4154 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4156 * Added public key authentication support to OPER and SILCOPER
4157 commands in the client library. Affected file is
4158 lib/silcclient/command.c.
4160 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4162 * Changed the get_auth_methdod client operation to be asynchronous.
4163 It can be async if the application resolves the authentication
4164 method from the server during the negotiation. Added new
4165 SilcGetAuthMeth completion callback that the application will
4166 call after resolving the authentication method.
4168 Added function silc_client_request_authentication_method that
4169 the application can use to resolve the authentication method
4170 from the server. Added also SilcConnectionAuthRequest callback
4171 that the library will call after the server has replied. The
4172 application can call this function if it does not know the
4173 current authentication method.
4175 Affected files are lib/silcclient/client.c and
4176 lib/silcclient/silcapi.h.
4178 * The Irssi SILC client now automatically resolves the authentication
4179 method incase any configuration information is not present (and
4180 currently there never is). The affected file is
4181 irssi/src/silc/core/client_ops.c.
4183 * Fixed public key authentication from the client library.
4184 Affected file lib/silcclient/protocol.c. Changed also the
4185 protocol specification about the public key authentication in
4186 the connection authentication protocol. The actual data to be
4187 signed is now computed with a hash function before signing.
4189 * Fixed the public key authentication from the server as well.
4190 Affected file silcd/protocol.c.
4192 * Removed the mlock()'s from the memory allocation routines.
4193 Affected file lib/silcutil/silcmemory.c. The ./configure does
4194 not check anymore for the mlock(). Affected file is
4197 * Fixed USERS command in server to allow the execution of the
4198 command for private and secret channels if the client sending
4199 the command is on the channel. Affected file silcd/command.c.
4201 * Fixed silc_client_get_clients_local to return the clients
4202 count correctly. It could return wrong value. Affected file
4203 lib/silcclient/idlist.c.
4205 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4207 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4208 types. The assembler optimizations seemed not to like 64-bit
4209 data types. The assmebler optimizations thus are now enabled
4210 also for BSD systems as opposed to only enable them for Linux.
4212 * Do not check for threads at all on BSD systems. Affected
4213 file configure.in.pre.
4215 * Removed -n and -h options from the Irssi SILC Client since
4216 they are not used in silc.
4218 * Fixed the prime generation to assure that the first digit
4219 of the generated random number is not zero since our conversion
4220 routines does not like number strings that starts with zero
4221 digit. If zero digit is seen the random number is regenerated.
4222 This caused some corrupted RSA keys when the zero first digit
4223 was met. Affected file lib/silcmath/silcprimegen.c.
4225 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4227 * Fixed WIN32 configuration in the ./configure script.
4228 Fixed to include xti.h on environments that has it.
4229 Patches by Carsten Ilchmann and andrew.
4231 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4233 * Changed the silc_id_create_client_id to be collision
4234 resistant. It is now assured that there cannot be created
4235 two same client ID's. I suspect that some weird bugs in
4236 the server were actually caused by duplicate Client IDs.
4237 Affected file silcd/serverid.[ch]. A router receiving
4238 new ID now also assures and informs the sending server
4239 if the ID caused collision.
4241 * Changed the silc_id_create_channel_id to also assure that
4242 there are no collisions.
4244 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4246 * Statement about ignoring the Mutual Authentication flag when
4247 performing rekey with PFS was a bit misleading. It is ignored
4248 if it was set in the initial negotiation, it cannot be even
4249 set in the rekey. Fixed in the ke-auth draft. Started the
4250 new versions of the protocol drafts in the doc/.
4252 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4254 * Fixed a bug in silc_client_command_identify_save when saving
4255 new channel information. The channel name was no duplicated
4256 and caused crash on exit. Affected file is
4257 lib/silcclient/command_reply.c.
4259 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4261 * Fixed the getkey command handling in the server. Send just
4262 empty OK reply to the sender if the key could not be fetched
4263 (but everything else was ok, like the key just was not available).
4264 Changed the public key parameter to optional in the protocol
4265 specs so that empty OK reply can be sent. Affected file
4268 Added a message to Irssi SILC client to tell to user if the
4269 server did not return a public key.
4271 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4273 * Fixed a channel key regeneration bug. It registered new
4274 timeout tasks exponentially until all system resources were
4275 used. Affected file silcd/server.c.
4277 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4279 * Added the SILC Document generator to the scripts/silcdoc.
4280 It can be used to generate the Toolkit Reference Manual out
4281 of the source tree. Internally it will also use the RoboDoc
4282 generator now imported in util/robodoc.
4284 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4286 * Added couple of return's in rekey protocol if error orccurred
4287 during the protocol. The execution must be terminated.
4288 Affected file silcd/protocol.c. Also, terminate the protocol
4289 always with timeout.
4291 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4293 * The client's Client ID was created initally from the wrong
4294 nickname (it could have been in format nick@host) in the
4295 silc_server_new_client. Affected file silcd/packet_receive.c
4297 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4299 * Added some SILC_LOG_ERROR's to various error conditions
4300 if client could not be added to ID cache. Affected files
4301 silcd/packet_receive.c and silcd/server.c.
4303 * When client's sock->user_data is freed, NULL also the
4304 client->router and client->connection pointers. Added check
4305 for these pointers being NULL to various places around the
4306 code. Affected file silcd/server.c.
4308 * Added client->data.registered == TRUE checks to various
4309 places around the code to assure that unregistered client's
4310 are not handled when it is not allowed. Affected file
4313 * Added `bool registered' fields to all
4314 silc_idlist_[server|client]_get_* routines to indicate whether
4315 the fetched client needs to be registered or not. Affected
4316 file silcd/idlist.[ch].
4318 * Add your own entry as registered to the ID cache in the
4319 server. Affected file server.c.
4321 * Fixed a bug in silc_server_new_server. The SilcServer was
4322 set as the new server's context instead of SilcServerEntry.
4323 This naturally caused some weird bugs.
4325 * Added "updated" field the SilcChannelEntry which indicates
4326 the time since the channel entry was last accessed. This
4327 can be used to determine whether it is necessary to
4328 announce the channel after backup resuming protocol.
4329 Affected files silcd/idlist.[ch].
4331 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4333 * Do not delete the channel rekey task when adding it
4334 for in silc_server_create_channel_key.
4336 * Changed the silc_server_create_channel_key to return
4337 TRUE or FALSE to indicate the success of the channel key
4340 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4342 * Fixed MSVC++ project files and added missing files to
4343 Makefiles under win32/.
4345 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4347 * Do not add TCP_NODELAY flag if the operating system
4348 does not have it defined. Affected files are
4349 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4351 * Fixed buffer overflow from Irssi SILC Client. Affected
4352 file irssi/src/fe-common/core/themes.c.
4354 * Fixed double free in client library in the file
4355 lib/silcclient/client.c when disconnecting from server.
4357 * Applied double free patch from cras to Irssi SILC client.
4358 Affected files irssi/src/core/[modules/expandos].c
4360 * Fixed the disconnection handling to Irssi SILC Client.
4361 The application must call silc_client_close_connection
4362 in ops->connect client operation in case of failure of
4363 the connection. Affected file is
4364 irssi/src/silc/core/client_ops.c.
4366 * Do not set sock->protocol to NULL in the function
4367 silc_client_close_connection after executing the protocol's
4368 final callback since the sock might not be valid anymore.
4369 Affected file lib/silcclient/client.c.
4371 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4373 * Do not enable SILC_THREADS if the linking with libpthread
4374 did not happen. Affected file configure.in.pre.
4376 * Added notion to protocol specification that server must
4377 verify the sent authentication payload with CMODE when
4378 setting the channel founder key. Implemented it to the
4379 server. Affected file silcd/command.c.
4381 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4383 * Added _EXTRA_DIST SILC distribution variable to the
4384 distributions file. It is used to conditionally add extra
4385 files or directories to the specific distribution. Affected
4386 files ./prepare, Makefile.am.pre and distributions.
4388 Removed the `_' from the start of the distribution names.
4391 * Added README.WIN32 for instructions to compile the Toolkit
4394 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4396 * Fixed a double free in disconnection in the server. Affected
4397 file is silcd/server.c.
4399 * Fixed the lib/silcske/groups.c to work now also with GMP
4400 MP library. The string conversion did not work when using
4401 specific base and the base is indicated in the string as well.
4403 * Created win32/ directory which now includes MSVC++ specific
4404 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4405 It will appear only in the toolkit distribution
4407 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4409 * Changed the key material distribution function in case when
4410 the hash output is too short. The data is now concatenated
4411 a bit differently than it used to. Made the change to the
4412 SKE protocol specification.
4414 * Added better GMP detection to configure.in.pre. A patch
4417 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4419 * Fixed a minor bug in SKE that might cause some problem on
4420 some platforms. Affected file lib/silcske/silcske.c.
4422 * Added the cookie checking for initiator in the SKE. It checks
4423 that the responder returns the sent cookie unmodified. The
4424 affected file is lib/silcske/silcske.c. Added new SKE
4425 error type INVALID_COOKIE that can be sent during the
4426 negotiation. Fixed some memory leaks as well.
4428 * Added the "invalid cookie" error message to Irssi SILC client's
4431 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4433 * Added `task_max' field to the SilcClientParams to indicate
4434 the maximum tasks the scheduler can handle. If set to zero,
4435 default values are used. Affected file lib/silcclient/silcapi.h.
4437 * Fixed memory leaks in silc_client_close_connection. Affected
4438 file lib/silcclient/client.c.
4440 * Added silc_client_del_client_entry to client library to free
4441 all memory of given client entry. Affected file is
4442 lib/silcclient/idlist.[ch].
4444 * Added new functions silc_client_del_channel and
4445 silc_client_del_server to delete channel and server entries.
4446 Affected file lib/silcclient/[silcapi.h/idlist.c].
4448 * Removed silc_client_del_client_by_id from silcapi.h.
4450 * Fixed the INFO command to return the server's own info
4451 correctly when querying by Server ID. Affected file is
4454 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4456 * Removed the non-blocking settings in WIN32 code in the
4457 silc_sock_[read/write] and added SleepEx instead. Affected
4458 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4459 of input data is now checked with FIONREAD and ioctlsocket.
4461 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4463 * Call silc_schedule_task_del_by_context in the
4464 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4465 Affected file lib/silccore/silcprotocol.c.
4467 * Call silc_protocol_cancel for active protocols in the
4468 silc_server_close_connection if the funtion
4469 silc_server_free_sock_user_data has not been called.
4470 Affected file silcd/server.c.
4472 * Generic tasks cannot be deleted using the del_by_fd
4473 task deleting function since generic tasks does not match
4474 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4476 * Added a notion to SILCOPER help file that the SILCOPER works
4477 only on router server, not on normal server.
4479 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4481 * Added for WIN32 support for the new scheduler as well.
4482 Affected file lib/silcutil/win32/silcwin32schedule.c.
4484 * Fixed the SHA1 implementation to work on various platforms.
4486 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4488 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4489 API. It is part of the scheduler now. Everything else is
4490 as previously but some functions has changed their names.
4491 Checkout the lib/silcutil/silcschedule.h for the interface.
4492 Updated all applications to use the new interface. Affected
4493 files are lib/silcutil/silcschedule.[ch].
4495 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4497 * Found a bug in the SKE implementation. The HASH value,
4498 specified by the protocol, was not computed correctly. The
4499 public key of the responder was not added to the computation
4500 even though it is mandatory. Affected file lib/silcske/silcske.c.
4501 This unfortunately causes incompatibilities with older
4502 clients and servers.
4504 * Added WIN32 specific network init and uninit functions:
4505 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4506 the Winsock2. Affected file lib/silcutil/silcnet.h and
4507 lib/silcutil/win32/silcwin32net.c.
4509 * Set the socket always to nonblocking mode on WIN32 after
4510 reading data or writing data. Affected file is
4511 lib/silcutil/win32/silcwin32sockconn.c.
4513 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4515 * Fixed various compilation problems under WIN32. Affected
4516 files lib/silcutil/win32/silcwin32thread.c and
4517 lib/silcutil/win32/silcwin32schedule.c.
4519 * Removed all _internal.h #includes from public header
4520 files. Internal headers must never be included from
4523 Removed also the lib/silcske/payload_internal.h file.
4525 * All include files that may be needed (public and some others
4526 included by the public headers) by application developers are
4527 now copied to the ./includes directory. It does not copy any
4528 internal headers. Affected file Makefile.defines.pre and all
4529 Makefile.am's under lib/ and subdirs.
4531 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4533 * Do not change the ~/.silc directory's permissions automatically.
4534 Affected file irssi/src/silc/core/clientutil.c.
4536 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4538 * Do not cancel the protocol in silc_server_close_connection
4539 it might cause recursion. Now cancelled in the function
4540 silc_server_free_sock_user_data. Affected file silcd/server.c.
4542 * Fixed the silc_server_remove_clients_by_server to regenerate
4543 the channel keys correctly finally. Added also new function
4544 silc_server_remove_clients_channels to actually do it.
4545 Affected file silcd/server.c.
4547 * Fixed the silc_server_new_channel to not crash by giving
4548 wrong router to the new channel. Affected file is
4549 silcd/packet_receive.c.
4551 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4553 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4554 which is given as argument to the silc_client_alloc now.
4555 It can be used to configure the client and set various parameters
4556 that affect the function of the client.
4558 * The USERS command in server did not check whether the channel
4559 is private or secret. Affected file silcd/command.c.
4561 * Added new argument to the USERS command in protocol specification.
4562 The USERS command now can take the channel name as argument
4563 as well. Added support for this in client and server and
4564 updated the protocol specs.
4566 * Completed the GETKEY command in client. It can be now used
4567 to fetch also servers public key not only some clients.
4568 Affected files lib/silcclient/command[_reply].c.
4570 * Added silc_client_get_server to return server entry by the
4571 server name. Affected files lib/silcclient/silcapi.h and
4574 * Redefined the IDENTIFY command in protocol specification to be
4575 more generic. It now can be used to query information about
4576 any entity in the SILC Network, including clients, servers and
4577 channels. The query may be based either the entity's name
4578 or the ID. Added support for this in both client and server.
4580 Affected files silcd/command.c and lib/silcclient/command.c
4581 and command_reply.c.
4583 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4584 the _from_client and _from_server functions. Affected file
4587 * Added silc_client_get_channel_by_id_resolve to the file
4588 lib/silcclient/silcapi.h to resolve channel information by
4589 its ID. Added also silc_client_get_channel_by_id that
4590 does not resolve it from the server.
4592 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4594 * Added SilcServerEntry context into the client library
4595 to represent one server. The INFO command now allocates
4596 these to save the resolved server info. For now on the
4597 client library will also keep information about servers,
4598 connected and resolved with INFO.
4600 The INFO command now allocates the SilcServerEntry context
4601 and saves the server info there. The COMMAND_REPLY in
4602 the INFO now returns the parameters to application in
4603 same order as defined in the protocol specification.
4605 The entries are cached in the client->server_cache.
4607 * The INFO command is now issued after received the Client ID
4608 from the server. Affected file lib/silcclient/client.c.
4610 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4611 to the application as the mode changer might be server.
4612 It is guaranteed that NULL is not returned anymore to the
4613 application. Affected file lib/silcclient/client_notify.c.
4615 The ID Type is now also passed to the application so that
4616 it can check whether the returned entry is SilcClientEntry
4619 Added new function silc_client_get_server_by_id to return
4620 the server entry by ID. Affected files are the
4621 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4623 * Do not create the channel in the Irssi SILC Client when issuing
4624 the JOIN command but when received the sucessful JOIN command
4625 reply. Otherwise the channel might get created even though we
4626 could not join it. The Affected file is
4627 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4629 * Fixed a channel joining bug in router. The router must also
4630 check the channel modes, invite and ban lists etc. when serving
4631 the JOIN command sent by normal server. Affected file is
4632 silcd/command.c. The router now resolves the client's
4633 information from the server who sent the JOIN command if it
4634 does not know it, and processes the JOIN command only after
4637 * Changed the SilcCommandCb to take new argument; void *context2.
4638 Affected file lib/silccore/silccommand.h
4640 The second argument in the command callbacks in the server now
4641 includes the SilcServerCommandReplyContext if the command was
4642 called as pending command callback from the command reply.
4643 Otherwise it is NULL. When called as pending the status of the
4644 command reply will be checked and if it was erronous the
4645 error will be sent to the original sender of the command.
4646 This way the client always receives the error messages even
4647 though the server was actually the one who received the error
4648 when it resent the command to router, for example. Affected
4649 files silcd/command[_reply].[ch].
4651 * Fixed sending WHOWAS command's error message to client if
4652 the requested client could not be found. It was missing.
4655 * Changed the CMODE and CUMODE commands reply arguments in the
4656 protocol specification. The Channel ID is now sent in both
4657 of the commands to identify the channel. Implemented this
4658 new feature to the client and server. Affected files
4659 lib/silcclient/command_reply.c and silcd/command.c.
4661 * Made better checks for invite and ban lists in the JOIN
4662 command in server. Affected file silcd/command.c.
4664 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4666 * The server now performs the incoming host IP/DNS lookup
4667 using the silc_socket_host_lookup and thus does not block
4668 the server anymore. Affected file silcd/server.c.
4670 * Completed the multi-thread support for SILC Scheduler in
4671 the lib/silcutil/silcschedule.c.
4673 * Fixed the configure.in.pre to detect the pthread correctly
4676 * Fixed a deadlock in silc_task_queue_wakeup in the file
4677 lib/silcutil/silctask.c.
4679 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4681 * Added new function silc_schedule_wakeup that is used in
4682 multi-threaded environment to wakeup the main thread's
4683 schduler. It needs to be used when a thread adds a new task
4684 or removes a task from task queues. After waking up, the
4685 scheduler will detect the task queue changes. If threads
4686 support is not compiled in this function has no effect.
4687 Implemented the wakeup mechanism to both Unix and WIN32
4688 systems. Affected files are lib/silcutil/silcschedule.[ch],
4689 lib/silcutil/unix/silcunixschedule.c and the
4690 lib/silcutil/win32/silcwin32schedule.c.
4692 * Added new function silc_task_queue_wakeup to wakeup the
4693 scheduler by the specified task queue. Affected file
4694 lib/silcutil/silctask.[ch].
4696 * The silc_socket_host_lookup_start now wakes up the scheduler
4697 after adding the timeout task. Affected file is
4698 lib/silcutil/silcsockconn.c.
4700 * The silc_socket_host_lookup is synchronous now if the threads
4701 support is not compiled in. However, the callback is still
4702 called asyncronously through the scheduler, anyway. Affected
4703 file lib/silcutil/silcsockconn.c.
4705 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4707 * Added new function silc_socket_host_lookup to perform
4708 asynchronous IP and FQDN lookups for the socket connection.
4709 Affected files lib/silcutil/silcsockconn.[ch].
4711 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4713 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4714 that may or may not compile the mutex support in.
4716 Changed the silc_mutex_alloc interface. It allocates the
4717 mutex now to the sent pointer and returns TRUE or FALSE.
4719 Affected file lib/silcutil/silcmutex.h.
4721 * Wrote the SILC Task Queue interface to support multi-threads.
4722 Affected file lib/silcutil/silctask.[ch].
4724 * Wrote the SILC Scheduler to support multi-threads. Affected
4725 file lib/silcutil/silcschedule.c.
4727 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4729 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4730 in lib/silcutil/win32/.
4732 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4734 * Defined SILC Mutex API and SILC Thread API and implemented
4735 them for Unix. Affected files are
4736 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4737 lib/silcutil/unix/silcunixmutex.c and
4738 lib/silcutil/unix/silcunixthread.c.
4740 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4742 * Fixed the silc_server_remove_clients_by_server's channel
4743 key re-generation. The hash table handling was incorrect
4744 and would not work with many channels. Affected file is
4747 * Fixed some memory leaks around the server code.
4749 * Rewrote the silc_server_get_users_on_channel to support IPv6
4750 based Client ID's. Affected file silcd/server.c.
4752 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4753 specification. However, a separate document must be written
4754 to define the detailed signing procedure and the payload
4755 associated with the flag. Defined the flag to the
4756 lib/silccore/silcchannel.h as well.
4758 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4760 * Changed the dynamic tables to static size tables in the
4761 lib/silccrypt/silchmac.c.
4763 * Removed GCC dependencies from the code. A patch by cras.
4765 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4767 * Do not show the error "Error receiving packet bla bla"
4768 in server if it really was not an error (-2 means that reading
4769 is pending). Affected file silcd/server.c.
4771 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4773 * Fixed a possible crash in silc_server_remove_clients_by_server
4774 in silcd/server.c. Fixed there also some memory leaks.
4776 * Fixed the silc_idlist_replace_client_id. It could replace
4777 wrong key in the hash table. Affected file silcd/idlist.c.
4779 * Do not check whether there are global users on the channel
4780 if the channel->global_users is FALSE. Affected functions
4781 silc_server_remove_from_one_channel and
4782 silc_server_remove_from_channels in silcd/server.c. Also,
4783 do not check if the removed client is local as we can be
4784 sure that global client was not removed from the channel
4785 and checking for global users is not needed.
4787 * The silc_server_remove_clients_by_server now re-generates
4788 the channel keys correctly for those channels that had
4789 clients removed from them. Affected file silcd/server.c.
4791 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4793 * Found the reason of random crashes in the server. We weren't
4794 ignoring the SIGPIPE signal (which can be sent in write())
4795 and it crashed the server. Affected file silcd/silcd.c.
4797 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4799 * Assure that sock->user_data is not NULL in the function
4800 silc_server_packet_send in silcd/packet_send.c.
4802 * Disconnect the remote connection if it could not be added
4803 to any ID lists in the server. The affected file is
4806 * Check in silc_server_packet_send[_real/dest] that the
4807 socket is not disconnecting and ignore the data if it is.
4808 Affected file silcd/packet_send.c.
4810 * Define inline to __inline on native WIN32 compilation.
4811 Affected file includes/silcwin32.h.
4813 * Added some explicit type casts for inline code since MSVC
4814 require them. Affected files lib/silcutil/silcbuffer.h,
4815 lib/trq/silcdlist.h and lib/trq/silclist.h.
4817 * Print warning in log files from now on if the packet
4818 decryption fails. Affected file silcd/server.c.
4820 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4822 * Changed the `say' client operation's interface to accept
4823 new `type' argument to indicate the type of the message sent
4824 by the library. The application may filter the library's
4825 messages according the type. The affected file is the
4826 lib/silcclient/silcapi.h.
4828 * Added two new functions to lib/silcclient/silcapi.h:
4829 silc_client_del_client and silc_client_del_client_by_id.
4830 Affected file lib/silcclient/idlist.c.
4832 * Moved the clientincludes.h from includes/ to silc/ and
4833 serverincludes.h from includes/ to silcd/.
4835 * The modes for the CMODE and CUMODE are now passed as
4836 uint32 for application with COMMAND_REPLY. The affected
4837 file is lib/silcclient/command_reply.c.
4839 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4841 * /WHOIS without arguments shows client's own information.
4842 Affected file lib/silcclient/command.c.
4844 * Changed PING to not accept any arguments. The specs
4845 says that client can ping only the connected server so
4846 requiring an argument is not needed. Affected file is
4847 lib/silcclient/command.c.
4849 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4851 * Fixed a fatal bug in private message sending and reception
4852 encryption and decryption when using private message keys.
4853 The implementation was incorrect and did not follow the
4854 specification. It causd that some of the message were
4855 lost since it did not use the sending and receiving keys
4856 as the protocol suggests. This has been fixed and will cause
4857 incompatibilities with older clients when sending private
4858 message encrypted with private message keys. Affected files
4859 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4860 and various other in Irssi SILC Client.
4862 Added `responder' boolean argument to the functions
4863 silc_client_add_private_message_key[_ske] to indicate when
4864 the key is added as responder or initiator of the key
4867 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4869 * Removed the silc_ske_check_version function and created
4870 a SilcSKECheckVersion callback. Added also a function
4871 silc_ske_set_callbacks that is now used to set all SKE
4872 callbacks. The callback functions are not given to
4873 the SKE functions anymore, but this function is used to
4876 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4878 * Added `silc_version' argument to the silc_client_alloc
4879 to define the version of the application for the library.
4880 The library will use the version string to compare it
4881 against the remote host's (usually a server) version
4882 string. Affected file lib/silcclient/silcapi.h
4884 * Added the KE protocol context to Key Agreement context
4885 in client library so that we can abort the SKE if it
4886 is in process when we get timeout. Affected file is
4887 lib/silcclient/client_keyagr.c.
4889 * Do not resolve the client ID forever if it returns in the
4890 first time that such client does not exist. This was done
4891 for example with private message. Affected file is
4892 lib/silcclient/client_prvmsg.c.
4894 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4896 * Do not add regex.h for WIN32. The affected file
4897 includes/silcincludes.h.
4899 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4900 not work yet 100%. It generates the DLL's automatically
4901 when compiling with --with-win32 under cygwin.
4903 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4905 * lib/contrib/regex.c is not compiled on WIN32.
4907 * Added silc_net_get_socket_opt function to the
4908 lib/silcutil/silcnet.h.
4910 * Added includes/silcwin32.h for WIN32 specific includes
4913 * Do not use ptime structure or any of the posix process
4914 functions on WIN32 in lib/silccrypt/silrng.c.
4916 * Added silc_gettimeofday to provide generic function
4917 for struct timeval on all platforms. Added the function
4918 to lib/silcutil/silcutil.h.
4920 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4922 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4923 library as they clearly belong there. As a plus side we
4924 can make the actual socket connection routines platform
4927 Added also new generic function silc_socket_read and
4928 silc_socket_write (that used to be silc_packet_[read/write].
4929 The implementation of these are platform specific.
4931 * Added WIN32 specific routines of silc_socket_[read/write]
4932 to lib/silcutil/win32/silcwin32sockconn.c.
4934 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4936 * Added preliminary support for native WIN32 compilation under
4937 cygwin (using the -mno-cygwin option for GCC) to the
4938 ./configure.in.pre. The --with-win32 now prepares the
4939 compilation for native WIN32.
4941 * Rewrote the SILC Scheduler interface in the file
4942 lib/silcutil/silcschedule.h. The scheduler is now context
4943 based and does not have anymore any global static scheduler.
4944 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4945 and created lib/silcutil/win32 directory for WIN32 based
4948 * Added Unix specific network routines to the
4949 lib/silcutil/unix/silcunixnet.c and the old
4950 lib/silcutil/silcnet.c includes now only generic routines.
4952 Added WIN32 specific network routines to the
4953 lib/silcutil/win32/silcwin32net.c.
4955 * Added Unix specific utility functions from the
4956 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4958 * Added WIN32 SILC Scheduler to the file
4959 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4962 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4964 * Do not handle JOIN notify in the server if the target client
4965 is not registered (idata->registered == FALSE). The affected
4966 file is silcd/packet_receive.c.
4968 * Update the nickrec->founder in event_cumode in the Irssi SILC
4969 client. Affected file irssi/src/silc/core/silc-channels.c.
4971 * Fixed the CUMODE_CHANGE notify handling in the server when
4972 server and router are announcing their clients on channels.
4973 Now the mode changes are saved and notified correctly. The
4974 affected file is /silcd/packet_receive.c.
4976 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4977 They really did not replace the cache entry in the ID Cache.
4978 Now they do that. Affected file silcd/idlist.c.
4980 * Fixed the KICK notify handling in the Irssi SILC client to
4981 update the channel records so that the kicked client does not
4982 appear to be on the channel. The affected file is
4983 irssi/src/silc/core/silc-channels.c.
4985 * Always update the conn->current_channel when executing command
4986 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4988 * Fixed the KILL notify handling in Irssi SILC client to remove
4989 the killed client on all channels.
4991 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Fixed the silc_parse_command_line to remove extra spaces
4994 from the start and end of the arguments. Affected file is
4995 lib/silcutil/silcutil.c.
4997 * Cancel and free any active protocol in the function
4998 silc_server_close_connection. Affected file silcd/server.c.
5000 * Cancel and free any active protocol in the function
5001 silc_client_close_connction. Affected file is
5002 lib/silcclient/client.c.
5004 * Do not execute the KILL command for clients that are in
5005 history (ie. they are not in the network). Affected file is
5008 * Fixed KILL notify handling, client does not crash anymore.
5009 Affected file irssi/src/silc/core/silc-channels.c.
5011 * Reduced the default packet buffer size from 2048 to 1024 in
5012 lib/silccore/silcpacket.c.
5014 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5015 counter to the SKE context that is incresed when the SKE library
5016 performs async operation outside the library. If the outside
5017 process frees the SKE context and FREED status will be set
5018 and the library will detect after the sync operation that the
5019 libary is freed. The affected files are
5020 lib/silcske/silcske[_status].[ch].
5022 * Resolve the client entry information in the function
5023 silc_client_channel_message to assure that NULL pointer is not
5024 passed as client entry to the application. */
5026 * Fixed the task timeout calculation to assure that there is
5027 never negative timeouts. The affected file is
5028 lib/silcutil/silcschedule.c.
5030 * Fixed the channel user mode notification sending in server.
5031 It was sent point-to-point to the router (or to server by router)
5032 but it needs to be destined to a channel. The routines now
5033 supports sending the channel user mode notifys to the channels
5034 when announcing clients and channels. Affected files are
5035 silcd/server.c and silcd/packet_receive.c.
5037 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5038 It did not actually replace the old channel entry in the cache.
5039 Affected file lib/silcclient/client_notify.c.
5041 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Fixed a possible crash in silc_packet_send_prepare. It now
5044 assures always that there is enough space in the buffer and
5045 at the tail area of the buffer (for MAC).
5047 Fixed the inbound buffer reallocation in silc_packet_read.
5048 It was old code and did not handle the reallocation correctly.
5051 The affected file is lib/silccore/silcpacket.c.
5053 * Fixed buffer overflow in silc_parse_nickname in the file
5054 lib/silcutil/silcutil.c.
5056 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * make install generates new server keys only if there is not
5061 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5064 Added check that if the NOREPLY is set then we will not send
5065 the away message. This avoids infinite loop of away messages
5066 if both clients are away. The affected file is
5067 lib/silcclient/client_prvmsg.c.
5069 * Fixed client crash if /NICK was given without arguments.
5070 Affected file lib/silcclient/command.c.
5072 * Server does not send the invite list in INVITE command back
5073 to the client if the list was not altered. Added this notion
5074 to the protocol spec as well. Affected file silcd/command.c.
5076 Fixed possible crash in INVITE command by checking the
5077 value of silc_server_get_client_route command.
5079 * Fixed the INVITE notify type handling. The arguments are now
5080 taken in correct order and client does not crash. The affected
5081 file is irssi/src/silc/core/silc-channels.c.
5083 Removed the "Inviting xxx to channel" message from the
5084 client library away and let the application handle it.
5085 Affected file lib/silcclient/command.c. Added that message
5086 to Irssi SILC client's message formats.
5088 * Fixed CMODE command crash in client. It now checks the
5089 amount of arguments correctly and does not crash. The affected
5090 file is lib/silcclient/command.c.
5092 * Do not create new channel automatically in silc_channels_join
5093 but check whether the channel by that name already exists.
5094 Affected file irssi/silc/core/silc-channels.c.
5096 * Do not send the SERVER_SIGNOFF to router if the disconnected
5097 entity was the router. Affected file silcd/server.c.
5099 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5100 SILC client as it was missing from there.
5102 Added the handling of the KICK notify to the Irssi SILC client
5103 as it was missing. Added "you have been kicked" message to
5104 Irssi SILC client's message modules formats.
5106 Added the handing of the KILL notify to the Irssi SILC client
5107 as it was missing. Added the kill message module formats
5110 The affected file is irssi/src/silc/core/silc-channels.c.
5112 * The router did not save the channel mode the server announced.
5113 Affected file silcd/packet_receive.c.
5115 * Fixed a possible crash in INFO command in server. If the
5116 server did not provide the server info it crashed. Affected
5117 file silcd/command.c.
5119 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Fixed the GETKEY command in the server to check also the
5122 global list. Otherwise the GETKEY would not work correctly
5123 in normal SILC server. Affected file silcd/command.c.
5125 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Fixed GETKEY crash, it crashed if the command did not succseed.
5129 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5132 is now real and not just an macro interface to GMP.
5134 Removed the entire GMP from the source tree and imported new
5135 NSS MPI library instead. Reason for removing GMP is that it is
5136 extremely large and compiles extremely slow. The NSS MPI
5137 is only a few files and compiles in less than 10 seconds.
5138 The speed is also about the same as GMP. The MPI is imported
5139 to lib/silcmath/mpi.
5141 If the system has GMP installed we will still use the GMP.
5142 If it is not then the NSS MPI will be compiled.
5144 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Merged a long nickname (127 characters long) crash bugfix from
5147 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5149 * Merged a freed memory reference bugfix from Irssi CVS tree.
5150 Affected file irssi/src/core/commands.c.
5152 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Added the server's public key sving and verification to the
5155 server when performing the SKE. This was missing and the
5156 remote server's (or router's) public key was accepted without
5157 checking whether we have it previously or trust it at all.
5158 Affected file silcd/protocol.c.
5160 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Check in the silc_server_timeout_remote if protocol is active
5163 and make sure that the protocol's final callback is called so
5164 that all memory if freed. Affected file silcd/server.c.
5166 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * silc_server_whois_send_reply crashed the server if the nickname
5169 was 127 characters long. Affected file silcd/command.c.
5171 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Added sanity check to the silc_server_new_client. If the hostname
5174 is provided inside username then check that the provided hostname
5175 really is the same as the resolved one. If the hostname was not
5176 resolved then check it from the public key. Affected file is
5177 silcd/packet_receive.c.
5179 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5180 if the server disconnected us and the connection is not valid
5181 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5183 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5184 the library to the lib/silcutil/silcutil.[ch].
5186 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Close log file after open. Affected file
5189 lib/silcutil/silclog.c.
5191 * Check whether sock == NULL in silc_client_send_packet and return
5192 if it is. Affected file lib/silcclient/silcclient.c.
5194 * Check rec->entry == NULL in the Irssi SILC Client before
5195 sending the channel message. Affecte file is
5196 irssi/src/silc/core/silc-servers.c.
5198 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Merged a splitted window bugfix from Irssi CVS tree. The
5201 affected file is irssi/src/fe-text/textbuffer-view.c.
5203 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5204 It did not print nickname.
5206 * Improved the distributions system a bit.
5208 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5211 irssi/src/fe-text/gui-window.c.
5213 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5214 to in-active server. The affected file is
5215 irssi/src/silc/core/client_ops.c.
5217 * Resolve the client in USERS command reply if the entry does
5218 not have username resolved. The affected file is
5219 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5220 command to WHOIS command to really resolve stuff. The USERS
5221 is not used any more in any critical section so WHOIS can
5222 be used even though it might be slower than IDENTIFY.
5224 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5227 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Changed the protocol API a bit more consistent in the
5230 lib/silccore/silcprotocol.[ch].
5232 * Changed the following headers to ROBODoc format:
5234 lib/silccore/silcpayload.h
5235 lib/silccore/silcprotocol.h
5236 lib/silccore/silcsockconn.h
5238 All core library headers are now formatted.
5240 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Fixed a bug in Irssi SILC client; do not show that you are
5243 server/router operator if you really are not. Affected file is
5244 irssi/src/silc/core/client_ops.c.
5246 * Renamed silc_command_free_payload to silc_command_payload_free.
5247 Affected file lib/silccore/silccommand.h
5249 * Added silcmath.h to include the prototoypes of various routines
5250 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5253 * Changed the following headers to ROBODoc format:
5255 lib/silccore/silcchannel.h
5256 lib/silccore/silccommand.h
5257 lib/silccore/silcid.h
5258 lib/silccore/silcidcache.h
5259 lib/silccore/silcmode.h
5260 lib/silccore/silcnotify.h
5261 lib/silccore/silcpacket.h
5262 lib/silcmath/silcmath.h
5264 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Added checking to the server code not to start the server if
5267 ciphers and stuff are not configured properly. Affected files
5268 silcd/serverconfig.[h] and silcd/server.c.
5270 * Changed the layout of the header files of the public interfaces
5271 in the SILC libraries. The new layout supports ROBODoc
5272 documentation tool (and some others) so that it is easy to create
5273 a library reference manual. All the other headers and source
5274 code must still follow the CodingStyle document. Also source
5275 code must not include these ROBODoc stuffs, only the headers.
5276 Furthermore, all public interface headers must now be named
5277 by using `silc' prefix, example: silcapi.h, silccipher.h.
5278 Some files were renamed due to this. All the other headers
5279 must not be used as public interfaces. I will update the
5280 CodingStyle document later. Changed following headers, so far:
5282 lib/silcclient/silcapi.h
5283 lib/silccore/silcauth.h
5284 lib/silccore/silcprivate.h
5285 lib/silccrypt/silcdh.h
5287 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Removed silc_client_packet_send_flush from the client library
5292 as it is not needed. Affected file lib/silcclient/client.[ch].
5294 * Added printing of message of unresolved authentication method
5295 to the Irssi SILC client. Added it to the module formats.
5296 Removed the same message from the client library.
5298 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Added new distribution feature, DISTLABEL. Every distribution
5301 can define own preprocessor label that can be used in the
5302 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5303 file distributions, acconfig.h.pre and prepare.
5305 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Added Makefile.defines_int to include the actual definitions
5308 for Makefile.defines.in. Tested the new distribution system,
5309 created distributions and tested installation.
5311 * Added AWAY message printing to the Irssi SILC client. Added
5312 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5314 * Added SCONNECT command to call the SILC's CONNECT command.
5315 Cannot use CONNECT directly since Irssi uses that internally.
5316 Affected file irssi/src/silc/core/silc-servers.c.
5318 Added ACTION local command. It is same as ME command but takes
5319 the channel as mandatory argument.
5321 Rewrote some of the Irssi's help files to suite for SILC
5324 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Added Makefile.defines[.in] that should for now on be included
5327 in all Makefile.am file in the source tree. That file includes
5328 all common compilation definitions for SILC source tree.
5330 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Minor changes to the ./prepare script to change the package
5333 name according the distribution name to the configure.in.
5335 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Created new distribution system. Added file `distributions'
5338 that defines all the distributions that can be created out of
5339 the SILC source tree. The ./prepare script now reads that
5340 file to determine how to prepare the distributions. The
5341 first argument to the ./prepare is the name of the distribution
5342 and second is the version of the distribution. If given
5343 without arguments it creates the default (toolkit) distribution
5344 with the default version (defined in ./prepare).
5346 All Makefile.am files that are subject to the distributions
5347 are now named as Makefile.am.pre. These are ./Makefile.am
5348 and lib/Makefile.am. Others may be changed later.
5350 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added invite list, ban list, some key management and connection
5353 error message printing to module formats in the Irssi SILC client.
5355 * Added new silc_client_set_away_message to set the away message
5356 that is back to the person who sent private message. The
5357 affected file lib/silcclient/silcapi.h and the
5358 lib/silcclient/client_prvmsg.c.
5360 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Fixed the private message sending in the Irssi SILC client,
5363 added local command KEY to the Irssi SILC client.
5365 Added key management and key agreement message formats to the
5366 irssi/src/fe-common/silc/module-formats.[ch].
5368 Added USERS (alias WHO) printing, server/router operator
5369 indication and LIST command printing to the module formats.
5371 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Fixed channel joining notify handling, cumode notify handling
5374 from Irssi SILC client.
5376 * Added SILC specific module-formats to the Irssi SILC client so
5377 that SILC specific message hilighting, colors etc is possible.
5378 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5380 Added channel mode, channel user mode, actions, notices,
5381 whois and whowas printing to the the module-formats.c.
5383 * Fixed a bug in channel deletion in the server. The channel
5384 is not left to the cache even if the channel founder auth mode
5385 is set when there are no users anymore on the channel. Affected
5386 file silcd/server.c.
5388 * The silc_net_localhost now resolves the entire hostname including
5389 the domain name. Affected file lib/silcutil/silcnet.c.
5391 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Changed the ask_passphrase client operation to be ascynchronous.
5394 It has now a completion callback and a context that the
5395 application must call after it has got the passphrase from
5396 the user. Affected files lib/silcclient/silcapi.h,
5397 lib/silcclient/protocol.c, lib/silcclient/command.c and
5400 Added SilcAskPassphrase callback that the application calls
5401 to deliver the passphrase to the library.
5403 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5404 The public key verification and especially a certificate
5405 verification is asynchronous procedure.
5407 Added new SILC_SKE_STATUS_PENDING status to indicate the
5408 request is pending and a callback will be called to finalize
5411 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5412 indicate that remote end did not send its public key (or
5413 certificate), even though we require it. Added check for this
5414 condition in the SKE. This was a security bug, now fixed.
5416 Defined new SilcSKEVerifyCbCompletion callback that is called
5417 when the verification process is completed.
5419 The affected files lib/silcske/silcske_status.h and
5420 lib/silcske/silcske.[ch].
5422 * Changed the verify_public_key client operation to be async
5423 as well. Defined SilcVerifyPublicKey callback that is used to
5424 indicate the success of the public key verification process.
5426 Changed the server and client to use the new async client
5429 * Changed the Irssi SILC client's internal scheduler to be called
5430 twice as many times as it used to be. As a result the client
5431 should be a bit faster now. Affected file is
5432 irssi/src/silc/core/silc-core.c.
5434 * Added support to Irssi SILC client of asynchronous public key
5435 verification and passphrase inquiry. Affected file is
5436 irssi/src/silc/core/silc-core.c.
5438 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Do not say "You have left channel %s" in client library.
5441 Moved it to the application. Affected files are
5442 lib/silcclient/command.c and silc/client_ops.c.
5444 * Fixed silc_client_get_clients. Command context was not
5445 duplicated and was freed memory in the callback. Affected
5446 file lib/silcclient/idlist.c.
5448 * Do not say "you are now talking..." on JOIN command in the
5449 client library. The appliation must handle it.
5451 * Do not say ".. changed topic to" in command reply in the
5452 client libary. The application must handle it.
5454 * Fixed TOPIC command sending in the client library.
5456 * Fixed a memory leak in silc_client_command_free in the file
5457 lib/silcclient/command.c.
5459 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Imported a modified version of Irssi client to the source tree.
5462 The Irssi will be used to create a new client called
5463 Irssi SILC. Imported to irssi/.
5465 Added silc_core_init_finish function to the Irssi. Affected
5466 file irssi/configure.in.
5468 A lot changes in the Makefile.ams around the irssi tree.
5470 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Do not rehash if the new size is same as the old size of the
5473 hash table, in the silc_hash_table_rehash*. The affected file
5474 lib/silcutil/silchashtable.c.
5476 * Replaced hash_table_del_by_context calls from the server
5477 (when channel->user_list and client->channels) to the
5478 hash_table_del as it is sufficient and faster.
5480 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added silc_hash_table_list, silc_hash_table_get and the
5483 SilcHashTableList structure to provide an alternative way to
5484 traverse the hash table. The affected files are
5485 lib/silcutil/silchashtable.[ch].
5487 * Changed the server's idlist routines to use the hash table
5488 routines to optimize the code.
5490 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Replaced the client entry's `channel' list and channel entry's
5493 `user_list' list to hash tables for optimized lookup. Changed
5494 the code to use the hash table interface around the code.
5495 Affected file lib/silcd/idlist.[ch].
5497 * Added `auto_rehash' boolean argument to the function
5498 silc_hash_table_alloc to indicate whether the hash table should
5499 auto-rehash when it thinks is appropriate time. It will
5500 increase the hash table size if the there is twice as much
5501 entries in the table than the size of the table, and will
5502 decrease the size if there are twice as less entries than
5503 the size of the table.
5505 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5509 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * silc_idcache_purge_by_context deletes the entry now by context
5512 as it is supposed to do. Affected file lib/silccore/idcache.c.
5514 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5515 client is not anymore valid (WHOWAS givens the info) and not
5516 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5518 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Removed the `data' and `data_len' arguments from the ID Cache
5521 interfaces and added `name' argument. ID Cache does not handle
5522 anymore the binary data only a names associated with given ID.
5524 * When hashing a Client ID with silc_hash_id the entire ID is
5525 not hashed anymore, instead only the hash of the Client ID is
5526 hashed. This way we can access the Client ID from the cache
5527 with Client ID but with the hash of the ID (which is a hash of
5528 the nickname) as well without any difference in performance.
5530 Added also silc_idcache_find_by_id_one_ext to do one on one
5531 searching when we have the actual ID. Added also function
5532 silc_hash_client_id_compare. The affected files are
5533 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5535 * When hashing the name associated with a ID it is always done
5536 in lowercase. This way we can access the cache without worrying
5537 about case-sensitivity, even though, for example nicknames are
5540 * Fixed a bug in server with channel message sending. It put
5541 wrong ID type as destination ID. The affected file
5542 silcd/packet_send.c.
5544 * silc_idcache_del_by_context now deletes from all hash tables
5545 by context. Affected file lib/silccore/idcache.c.
5547 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Changed the client library to use the new ID Cache interface.
5550 Changes around the source tree.
5552 * Added silc_hash_table_rehash_ext to rehash with specific
5553 hash function. Affected file lib/silcutil/silchashtable.[ch].
5555 * Added silc_hash_string_compare to compare two strings in the
5556 hash table. Affected file lib/silcutil/silcutil.[ch].
5558 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Added new function silc_idcache_del_by_context into the
5561 lib/silccore/idcache.[ch].
5563 * Changed the server's ID list routines to use the new ID Cache
5564 interface. Changes around the source tree.
5566 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Added silc_hash_table_del[_by_context]_ext functions in to the
5569 lib/silcutil/silchashtable.[ch].
5571 Removed silc_hash_table_find_all* routines and added new
5572 silc_hash_table_find_foreach to replace them.
5574 Added silc_hash_table_replace_ext function as extended
5575 replacing function. Separated the simple hash table interface
5576 from the extended hash table interface in the file
5577 lib/silcutil/silchashtable.h.
5579 * Fixed minor bugs and changed it to use some of the new
5580 hash table functions in lib/silccore/idcache.c
5582 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Added new function silc_hash_table_find_all to return all keys
5585 in the hash table by the specified key. As the hash table is
5586 collision resistant it also makes it possible to have several
5587 duplicate keys in the hash table. This function may be used to
5588 find all of the keys from the hash.
5590 Added user_context arguments to the SilcHashFunction,
5591 SilcHashCompare and SilcHashDestructor to deliver user specified
5594 Added new fuctions silc_hash_table_find[_all]_ext to do
5595 extended lookup with specified hash and compare functions and
5596 specified user contexts.
5598 Added new function silc_hash_table_add_ext to add the key
5599 with specified hash function and user context.
5601 Added new function silc_hash_table_foreach to traverse all
5602 entrys in the hash table. Added SilcHashForeach callback
5605 Added new function silc_hash_table_del_by_context to delete
5606 the entry only if the context associated with the key matches.
5608 Affected files are lib/silcutil/silchashtable.[ch].
5610 * Removed silc_hash_[server/client/channel]_id and added just
5611 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5612 silc_hash_id_compare to compare two ID's using as the hash table
5613 comparison function. Added also silc_hash_data to hash
5614 binary data and silc_hash_data_compare to compare it.
5616 * Removed silc_idlist_find_client_by_hash as it is not needed
5617 anymore. Affected file silcd/idlist.[ch].
5619 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5620 to use internally the SilcHashTable. The new ID Cache is a lot
5621 faster than the old one. Some of the ID Cache interface was also
5622 rewritten and obsolete and stupid functions were removed.
5624 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added entry_count field to the SilcHashTable to keep the number
5627 of the entries in the table. Implemented the function
5628 silc_hash_table_rehash. Added new function
5629 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5631 Fixed a minor bug in silc_hash_table_free.
5633 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5634 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5635 into the lib/silcutil/silcutil.[ch].
5637 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Implemented a collision resistant hash table into the
5640 lib/silcutil/silchashtable[ch]. See the header and the source
5641 for the SilcHashTable API.
5643 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Merged dotconf version 1.0.2 into lib/dotconf.
5647 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Do not compile anything in lib/silcsim/* if the SIM support
5650 is not enabled. The tree should now compile without problems
5653 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Compiled the SILC under cygwin. Compiled and tested briefly
5656 without problems. More tests needed. The SIMs didn't compile
5659 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5661 * Fixed possible crash in silc_get_username in the
5662 lib/silcutil/silcutil.c.
5664 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Fixed a va_arg in silc/client_ops.c.
5668 * Oops, RC5 routines were named AES and caused some problems
5669 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5671 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Added new SilcIDIP structure into the lib/silccore/id.h and
5674 replaced the old `ip' fields from all SILC ID's to that type.
5675 This is a step towards IPv6 support.
5677 The silc_id_get_len takes now the ID as an extra argument.
5678 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5679 both IPv4 and IPv6 based ID's.
5681 The affected files are lib/silccore/id.[ch] and other files
5682 around the tree using these routines.
5684 * Removed the ID length arguments in server from various
5685 silc_server_send_notify_* routines -> they are not needed
5688 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Fixed memory leak in silc_encode_pem_file in the file
5691 lib/silcutil/silcutil.c.
5693 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Check minor version as well in the SKE. Affected files are
5696 silcd/protocol.c and lib/silcclient/protocol.c.
5698 * Added --identifier option to the server so that an identifier
5699 can be when creating the public key for the server. Affected
5700 file is silcd/silcd.c.
5702 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5703 lib/silccrypt/silcpkcs.c.
5705 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5707 * Register default ciphers and stuff when using -C option with
5708 the server. Affected file sildc/silcd.c.
5710 * Put back the servers public key filename format, it is better
5711 than the new one. For now, the client keys are saved with the
5712 new filename format. The affected file silc/client_ops.c.
5714 * Implemented the Cipher API for the rest of the ciphers that
5715 did not implement it or implemented it the wrong way.
5717 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Register default ciphers and stuff when using the -S option
5720 in the client. Affected file silc/silc.c. Same also when
5721 creating new key pair with -C option.
5723 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Fixed the silc_verify_public_key client operation function to
5726 save the public keys differently. The fingerprint is now
5727 used as filename and not the hostname. This way also the
5728 client keys are saved uniquely and not with hostnames. The
5729 affected file is silc/client_ops.c.
5731 * Trimmed the silc_hash_fingerprint function to remove extra
5732 whitespaces from the end of the fingerprint. The affected
5733 file is lib/silccrypt/silchash.c.
5737 * Added silc_cipher_register_default function to register all
5738 default ciphers. It can be used when configuration files
5739 does not exist and the application does not want any specific
5740 ciphers in any specific order.
5742 The SilcDList is now used as silc_cipher_list dynamically
5743 allocated cipher list. Removed the static list all together
5744 and now all ciphers must be allocated to the dynamic list.
5745 The silc_cipher_alloc routine was changed to check only the
5748 All silc_cipher_* routines that used to return int returns
5751 The affected files lib/silccrypt/silccrypt.[ch].
5753 * The same thing was done to silc_hash_* as for silc_cipher_*
5754 routines. Affected files lib/silccrypt/silchash.[ch].
5756 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5757 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5758 Added also silc_pkcs_[un]register[_default] functions.
5759 Removed the data_context from the PKCS API.
5761 * Added silc_hmac_register_default function to register default
5762 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5763 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5764 to unregister all hmacs at once.
5766 * Register the default ciphers, hash functions, PKCSs and HMACs
5767 if client's configuration file does not exist. The affected
5770 * The client did not load the hash functions from the SIM
5771 modules at all. Added support for this. Affected file is
5772 silc/clientconfig.c.
5774 * When decoding public key with silc_pkcs_public_key_decode, check
5775 the supported algorithm only if PKCS are registered. Affected
5776 file lib/silccrypt/silcpkcs.c. The same was done with the
5777 silc_pkcs_private_key_decode.
5779 * Fixed the SILC List routines to keep the list always in order.
5780 It used to change the list's order when traversing the list but
5781 not it preserves the order. Affected file lib/trq/silclist.h.
5783 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Added the client library to use the SilcSocketConnection's
5786 reference counter (by silc_socket_dup) to prevent the bug that
5787 the socket object may be freed underneath async operation.
5789 * The name resolv library checking fixes in the configure.in.pre.
5792 * Created new version of the protocol drafts for future
5793 development. The -03 drafts are the ones that will be changed
5794 in the trunk now and the -02 will remain as they are.
5796 * Send list of CUMODE notifys to the router when announcing
5797 the channel users to the router. Affected file silcd/server.c.
5798 If the router receiving channel founder CUMODE for a channel
5799 that already has channel founder it will send CUMODE notify
5800 to the sender to remove the channel founder rights from the
5801 announced client. Affected file silcd/packet_receive.c.
5803 * The CUMODE notify may now use Server ID as well as the entity
5804 who changes the mode. Updated protocool specs.
5806 * Updated INSTALL and README files.
5808 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * New web pages in the http://silc.pspt.fi. The pages was
5815 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Implemented the [DenyConnectin] config section in the server.
5818 Added silc_server_config_denied_conn to check whether incoming
5819 connection is denied. Affected file silcd/serverconfig.[ch].
5821 * Do not check the ports when checking the incoming configuration
5822 data if the port is 0, meaning any. Affected file is
5823 silcd/serverconfig.c.
5825 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Fixed buffer overflow in silc_string_compare in the file
5828 lib/silcutil/silcutil.c.
5830 * Fixed double free in silc_server_command_leave in the file
5833 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Fixed the version checking in the server. Affected file is
5838 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Fixed the configuration data fetching when accepting new
5841 connections in the server. Affected file silcd/server.c.
5843 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added `sender_entry' argument to the function
5846 silc_server_packet_relay_to_channel so that we can check
5847 whether some destination actually belongs to the same route
5848 the sender belongs (ie, we must not resend the packet to the
5849 sender). Affected file silcd/packet_send.[ch].
5851 * Added `servername' field to the SilcClientEntry in the server
5852 to hold the name of the server where client is from. Affected
5853 file is silcd/idlist.h.
5855 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Moved the channel message encrypting in the router betwen
5858 router connections from silc_server_channel_message to the
5859 silc_server_packet_relay_to_channel since we want to check
5860 whether we have anybody channel before encrypting anything.
5861 Affected files silcd/packet_[receive/send].c.
5863 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Fixed the [AdminConnection] server config section to support
5866 multiple entries. Affected file silcd/serverconfig.c.
5868 * Added support into the server to check the validity of the
5869 incoming connection before executing any KE or authentication
5872 * The connection configuration is now saved to the KE and
5873 connection auth protocol contexts and not fetched anymore in
5874 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5876 * The local hosts listenning address and port is also resolved
5877 now when starting the server. We want to have the socket object
5878 to include the real address and port for the listener. Added
5879 new function silc_net_check_local_by_sock into the files
5880 lib/silcutil/silcnet.[ch].
5882 * Fixed a broadcast bug in server -> do not broadcast if we
5885 * Fixed a routing bug. Do not route broadcast packets ever.
5886 Broadcast packets must be processed always and not routed since
5887 they may be destined to some other host than yourself and thus
5888 would get routed without no good reason. Affected file is
5891 * Added function silc_server_config_is_primary_route to check
5892 whether primary router connection has been configured (a router
5893 configuration that we are initiating). If there is not, we
5894 will assume that there is only two routers in the SILC network
5895 and we will use the incoming router connection as our primary
5896 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5898 * Changed the order of the broadcasting. Broadcast _after_ the
5899 packet has been processed not before. Affected file is
5902 * Fixed a [ClientConnection] parsing bug. The port was never
5903 parsed correctly thus resulting to port 0. Affected file
5904 silcd/serverconfig.c.
5906 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5907 argument and did not set the broadcast packet flag. Affected
5908 file silcd/packet_send.c. Fixed same bug in the function
5909 silc_server_send_notify as well.
5911 * If we receive NEW_ID packet for our own ID in the server, ignore
5914 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Removed the nickname from the Private Message Payload.
5919 Updated the code and the protocol specs.
5921 * Updated protocol specs for submitting to the IETF.
5923 * Tweaked the Random Number Generator a bit. Affected file
5924 lib/silccrypt/silcrng.c. Exported a new function
5925 silc_rng_[global]_add_noise which can be used to add more
5928 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Do not parse packets with different timeout when protocol
5931 is active -> may cause problem with rekey. Affected file
5934 * When server receives signoff notify it must not create
5935 new channel key if the client is on any channels since the
5936 sender of the signoff notify will create it.
5938 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added printing of error messages during SKE protocol from the
5941 failure packet sent by server during SKE. Affected file
5944 * Removed the client's failure_callback handling with timeout
5945 and handle it immediately when received.
5947 * The SKE library returned wrong type in SUCCESS and FAILURE
5948 packets. They must be 32 bit MSB not 16 bit MSB.
5950 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Ok, rewrote the logic of the re-key and now it seems to work.
5953 I tested it on high traffic with frequent re-keys without
5954 problems. Added hmac_receive (and renamed hmac to hmac_send)
5955 in SilcClientConnection in lib/silcclient/client.h and
5956 in SilcIDListData in silcd/idlist.h. Also, removed the
5957 SilcPacketParserContext's cipher and hmac fields as they are
5958 not needed anymore and actually caused some problems when
5959 the ciphers and hmac's changed underneath the packet parser.
5961 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * If re-key protocol is active then process the incoming packets
5964 synchronously since we must assure that icoming packets encrypted
5965 with the old key is processed before the new keys is set to
5966 use. This is true other packets than for REKEY packets.
5967 Affected file silcd/server.c. The same was done to client library
5968 as well, affected file lib/silcclient/client.c.
5970 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Fixed bug in client and server to accept the force send if
5973 the packet is send from silc_[server/client]_packet_process
5974 function. Otherwise the packets are never delivered, oops.
5976 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Disable force sending of packets when REKEY protocol is active.
5979 We must assure that no packet is sent directly when rekey is
5980 performed. All packets must be sent through packet queue.
5981 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5982 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5983 function is silc_[server/client]_packet_send_real to check
5986 * Replaced the SIM paths from example config files to
5987 /usr/local/modules. Also, make install creates now
5988 /usr/local/silc/logs directory to hold all the SILC server
5991 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Made the configure.in.pre work on Solaris. Patch by salo.
5995 * Made all ciphers compatible with non-x86 machines. Defined
5996 CBC mode macros into lib/silccrypt/ciphers_def.h.
5998 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Fixed the make install.
6002 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * When MAC computation fails the silc_packet_decrypt returned 0
6005 even though it was supposed to return -1. Fixed this. The
6006 affected file is lib/silccore/silcpacket.c.
6008 * Do not replace the config files in /etc/silc (in make install)
6009 if they already exist. Affected file ./Makefile.am.
6011 * Do not send re-key packets immediately but through packet queue.
6012 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6014 * Changed silc_net_check_host_by_sock to return FALSE if the
6015 IP/DNS could not be resolved. Though, it returns the IP address
6016 now even if it could not resolve it (but returns also FALSE).
6017 Affected file lib/silcutil/silcnet.[ch].
6019 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Added silc_pkcs_decode_identifier to decode the public key's
6022 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6023 Added also silc_pkcs_free_identifier. Added also new context
6024 SilcPublicKeyIdentifier.
6026 * Added -S option to the silc client. It is used to dump the
6027 contents of the specified public key file.
6029 * Changed the PKCS api to return the public key length when
6030 setting the public key.
6032 * Fixed a fatal bug in the public and private key file loading.
6033 Affected file lib/silccrypt/silcpkcs.c.
6035 * Execute the packet parsing for client with zero (0) timeout
6036 if the protocol is active. Affected file silcd/server.c.
6038 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Made the key generation options to the silcd program. Added
6041 -C option, equivalent to client's option.
6043 * Added new [ServerKeys] config section to the server. It
6044 configures the server's public and private key.
6046 * Defined generic Public Key Payload into the protocol
6047 specification to send specific type of public keys and
6050 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6051 public key or certificate.
6053 * Implemented the GETKEY command to the server and to the
6054 client library and on user interface.
6056 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Made preliminary `make install' work.
6060 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Added SilcServerRekey context into silcd/idlist.h.
6064 * Added the PFS support as defined in the specification to the
6065 SKE protocol. Affected files lib/silcske/*.c.
6067 * Added `ske_group' field to the SilcServerRekey context to hold
6068 the number of the SKE group that is used with PFS in re-key.
6069 Affected file silcd/idlist.h.
6071 * Added PFS re-key support to the server. Affected file is
6074 * Added silc_protocol_cancel to cancel execution of the next
6075 state of the protocol. Affected file is
6076 lib/silccore/silcprotocol.[ch].
6078 * Added the re-key support with and without PFS to the client
6079 library. Re-key is performed once in an hour, by default.
6081 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6082 Added silc_client_rekey_callback and silc_client_rekey_final.
6083 Affected files are lib/silcclient/protocol.[ch] and
6084 lib/silcclient/client.[ch].
6086 * Removed the `hmac_key' and `hmac_key_len' fields from the
6087 SilcClientConnection structure; not needed. Affected file is
6088 lib/silcclient/client.h.
6092 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Do not ask whether user wants to use the negotiated private key
6095 for private messages, just use it. Affected file is
6096 silc/local_command.c.
6098 * Added `send_enc_key' and `enc_key_len' fields to the
6099 SilcIDListData structure since they are needed in the re-key
6100 phase. Affected file is silcd/idlist.[ch].
6102 * Implemented the simple re-key protocol into the server.
6103 Affected files silcd/server.c and silcd/protocol.[ch]. The
6104 re-key will be performed once in an hour, by default.
6106 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6107 Added silc_server_rekey, silc_server_rekey_callback and
6108 silc_server_rekey_final.
6110 * Removed Tunneled flag from the protocol. Updated the code
6111 and the specifications.
6113 * Adde `pfs' field to the SilcIDListData to indicate whether
6114 the PFS is to be performed in the re-key. Affected file is
6117 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6120 int64 of at least the xintXX size. If void * is less that 4
6121 bytes uint32 * will be used. Defined bool as boolean.
6123 * Changed _ALL_ unsigned long and unsigned int to uint32,
6124 unsgined short to uint16 in the source tree.
6126 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6127 not handle clients that has entry->data.registered == FALSE.
6128 They are not in the network anymore. Affected file is
6131 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6133 * Implemented the sending of the SERVER_SIGNOFF notify in the
6134 server. Affected file is silcd/server.c.
6136 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6137 Added also silc_notify_payload_encode_args into the
6138 lib/silccore/silcnotify.[ch].
6140 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6141 Affected file silcd/packet_receive.c.
6143 * Implemented the SERVER_SIGNOFF notify handling in the client
6144 library. Affected file lib/silcclient/client_notify.c. Also,
6145 implemnted the printing of the SERVER_SIGNOFF info to the
6146 application. Affected file silc/client_ops.c.
6148 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6149 if the deleting was successful. Affected file silcd/idlist.[ch].
6151 * Added support for public key authentication in the connection
6152 authentication protocol in the client library. Affected file
6153 lib/silcclient/protocol.c.
6155 * Changed the server's silc_idlist_get_clients_by_* interface
6156 to support already allocated array so that new entries may be
6157 added to pre-allocated array. Affected file silcd/idlist.[ch].
6158 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6159 and command replies.
6161 * All command reply functions in the server now calls the
6162 pending command callback even if error occured. This way the
6163 error will be delivered to the client as well. Affected files
6164 silcd/command.c and silcd/command_reply.c.
6166 * Fixed INFO command to return local server's info if no server
6167 was provided. Affected file lib/silcclient/command.c.
6169 * Removed RESTART command for good. Updated the code and the
6172 * Rewrote parts of the task system. It is a bit simpler now.
6173 Removed unsued task priorities. The affected files are
6174 lib/silcutil/silctask.[ch].
6176 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Moved the USERS printing from the library to the application.
6179 Affected files lib/silcclient/command.c and silc/client_ops.c.
6181 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * Added channel key re-key support. The re-key is perfomed
6186 only by the router and is done once in an hour. Added `rekey'
6187 field to the SilcChannelEntry in the server. Affected files
6188 silcd/server.c and silcd/idlist.h.
6190 * Added silc_task_unregister_by_context into the file
6191 lib/silcutil/silctask.[ch].
6193 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Added SILC_UMODE_GONE mode to indicate when the client is not
6196 present in the SILC network. Added also support to the local
6197 command AWAY that will set this mode. Added support of showing
6198 "xxx is gone" in WHOIS command. The USERS command shows the
6199 gone status as well.
6201 * Fixed setting server and router operator privileges in the
6202 server's UMODE command. Affected file silcd/command.c.
6204 * Merged the SKE KE1 and KE2 payloads into one payload. The
6205 new KE payload is equivalent to the old KE2 payload.
6207 Cleaned up the SKE Start Payload parsing. It now uses the
6208 simple buffer unformatting to do the parsing. A lot faster
6211 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6212 to the SKE that is used to indicate whether both of the SKE
6213 parties should perform authentication. By default only the
6214 responder performs authentication. By setting this flag also
6215 the initiator must do authentication. By default it is unset
6216 since in normal SKE case, client to server connection, only
6217 the responder should do authentication. When doing SKE between
6218 two clients both should perform authentication. Updated the
6219 code and the protocol specs.
6221 * A little fix to IDENTIFY command in the server. Search the
6222 client first by hash not nickname. Affected file is
6225 * Fixed the silc_client_close_connection to support closing
6226 the client to client connections wihtout deleting too much
6227 data. Affected file lib/silcclient/client.c.
6229 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6230 are received if protocol used to be active but is not anymore
6231 the application would crash due to NULL pointer dereference.
6232 Affected files silcd/server.c and lib/silcclient/client.c.
6234 * Added `hash' field to the SilcClientConnection to include
6235 the hash function negotiated in the SKE protocol.
6237 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6238 to set the channel founder authentication data. A client can
6239 claim the founder rights later by providing the authentication
6240 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6241 This way the channel founder can regain the channel founder
6242 privileges even it is left the channel. This works only on
6243 local server and the client must be connected to the same
6244 server to be able to regain the founder rights. Updated the
6245 protocol specs accordingly.
6247 Added support to the CMODE command in the client to set the
6248 founder auth data. Read the README to see how to set it.
6250 Added support to the CUMODE command to claim the founder
6251 rights. Read the README to see how to do it.
6253 Added support for the founder authentication to the Channel
6254 Entry in the server. Affected file silcd/idlist.h.
6256 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6257 server's CMODE command. Affected file silcd/command.c.
6259 * Added the following new functions into lib/silccore/silcauth.[ch]:
6260 silc_auth_get_method and silc_auth_get_data.
6262 * The server now saves the remote hosts public key to the
6263 SilcIDListData pointer. Affected file silcd/protocol.c.
6265 * The normal server now does not remove the channel entry from
6266 the cache if the founder authentication data is set. It used
6267 to remove it if the founder was the last one on the channel on
6268 the server and left the channel. The auth data is saved and
6269 if the channel is re-joined later the old entry is used with
6270 the old auth data. Affected files silcd/command_reply.c and
6273 * Removed the `pkcs' field from the SilcIDListData structure
6274 in the server; it is not used. Affected file silcd/idlist.h.
6276 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6278 * Fixed packet processing on slow links. Partial packets were
6279 never re-processed because the incoming data buffer was cleared
6280 by the application. Application must not directly clear the
6281 sock->inbuf, the packet processing routines handle it. Fixed
6282 this in client library and in server.
6284 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Fixed the WHOIS and IDENTIFY send reply function to really
6287 check whether to send list or just one entry. Affected file
6290 * Cleaned up the LEAVE command's channel key distribution. The
6291 affected file silcd/command.c.
6293 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6294 can enforce the channel mode as well. In that case the ID
6295 includes the ID of the server. The code now enforces the
6296 mode change if the router have different mode than the server.
6298 * The notify client operation with CMODE_CHANGE notify can now
6299 return NULL client_entry pointer if the CMODE was not changed
6300 by client. Application must check for this.
6302 * Added <Server ID> argument to INFO command to support server
6303 info fetching by Server ID.
6305 * Added silc_server_announce_get_channel_users to get assembled
6306 packets of channel users of the specified channel. Affected
6307 file silcd/server.[ch].
6309 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6310 was freed underneath the ID Cache.
6312 * Re-announce clients when the server received CHANNEL_CHANGE
6313 notify from the router. Affected file silcd/packet_send.c.
6315 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6318 crashed since it did not handle the fact that there is no cipher
6319 called "3" and didn't check the error condition. Now fixed.
6321 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6322 flag. It can be used to send message requests.
6324 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Implemented the RESTART command in the client.
6328 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6329 notice type messages. Added notice printing to the user
6332 * The channel keys are not re-generated if the channel's mode
6333 is PRIVKEY, ie private key on the channel exists. Affected
6334 files silcd/server.c and silcd/command.c.
6336 * Fixed a little bug in channel message delivery when channel
6337 private keys are set in the server. Affected file is
6338 silcd/packet_send.c.
6340 * Changed the setting on channel->on_channel = TRUE from the
6341 silc_client_save_channel_key to the JOIN command reply. The
6342 key payload is not received if the private channel key is set.
6343 Affected file lib/silcclient/command_reply.c and the
6344 lib/silcclient/client_channel.c.
6346 * When the CMODE_CHANGE notify is sent and the channel private
6347 key mode is removed the channel key must be re-generated in
6348 other cells as well. Added this support for the router in the
6349 silcd/packet_receive.c.
6351 * Added new local command NOTICE to send notice message on
6352 channel. Affected file silc/local_command.[ch].
6354 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * Added new local command ME to the client. It is used to send
6357 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6358 some action. Affected file silc/local_command.[ch].
6360 * Changed channel_message and private_message client operations
6361 to deliver the message flags to the application. Added also
6362 the `flags' arguments to the silc_client_send_channel_message
6363 and silc_client_send_private_message functions. Affected file
6366 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Redefined the Private Message Payload to support private message
6369 keys and to support the new private message flags. Updated
6370 the protocol specs. Flags makes it possible to have for example
6371 CTCP style messages.
6373 * Added new type SilcPrivateMessagePayload and defined an API
6374 for it in the lib/silcclient/silcprivate.[ch].
6376 * Tested private message private keys successfully. Tested the
6377 private message key set, unset and list commands with the new
6380 * Redefined the Channel Message Payload to include the channel
6381 message flags (equal with private message flags) to support
6382 for example CTCP style messages.
6384 * Defined some of the message (for channel and private message)
6385 flags. Updated the protocol specs and added the flags to the
6386 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6388 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Added SilcKeyAgreementStatus type to the key agreement routines
6391 to indicate the current status and error if one occured.
6392 The status types are defined in the lib/silcclient/silcapi.h.
6394 * Added new local command KEY that is used to set and unset private
6395 keys for channels, set and unset private keys for private messages
6396 with remote clients and to send key agreement requests and
6397 negotiate the key agreement protocol with remote client. The
6398 key agreement is supported only to negotiate private message keys,
6399 it currently cannot be used to negotiate private keys for channels,
6400 as it is not convenient for that purpose.
6402 * Fixed a minor pending callback setting bug in the function
6403 silc_client_get_client_by_id_resolve, now the function works.
6404 Affected file lib/silcclient/idlist.c.
6406 * Added function silc_net_get_local_port to get local bound
6407 port by socket. Added to lib/silcutil/silcnet.[ch].
6409 * Added `sockets' and `sockets_count' fields to the SilcClient
6410 object. They hold the sockets of the listenning sockets in
6411 the client. Listenning sockets may be for example the key
6412 agreement server. Affected file lib/silcclient/client.[ch].
6413 Added functions the silc_client_add_socket and the
6414 silc_client_del_socket. They are exported to the application
6417 * Added ~./silc/clientkeys to support other client's public keys.
6419 * Renamed verify_server_key client operation to verify_public_key
6420 and added one argument to indicate the type of the connection
6421 (server, client etc.).
6423 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Added silc_server_connection_auth_request to handle the
6426 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6427 silcd/packet_receive.[ch].
6429 * Added silc_server_send_connection_auth_request into the
6430 silcd/packet_send.c to send the connection auth request packet.
6432 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6435 * Fixed the public key authentication in responder side in the
6436 server. The `auth_data' pointer includes the SilcPublicKey
6437 not the path to the public key. Affected file silcd/protocol.c.
6439 * Implemented the public key authentication in the initiator side
6440 in the server. Affected file silcd/protocol.c.
6442 * Removed the [RedirectClient] config section from the server
6443 configuration. Is not needed and I don't want to implement it.
6445 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Cleaned up the CMODE command in the server. It now works
6448 correctly and supports all the modes defined in the protocol.
6449 Affected file is silcd/command.c.
6451 * Added `hmac_name' field to the SilcChannelEntry in the server
6452 to hold the default HMAC of the channel. It can be set when
6453 creating the channel (with JOIN command). Affected files
6456 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6457 type to indicate the change of the current cipher and hmac
6458 on the channel. Client can safely ignore the <cipher> argument
6459 (if it chooses to do so) since the CHANNEL_KEY packet will
6460 force the channel key change anyway. The <hmac> argument is
6461 important since the client is responsible of setting the new
6462 HMAC and the hmac key into use.
6464 * Fixed the CMODE command in the client library as well.
6466 * Tested CMODE command in router environment successfully.
6468 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Show the version of the remote client (or server) when connecting
6471 to the server. It is logged to the log file. Affected file
6472 is silcd/protocol.c.
6474 * Fixed the KILLED notify handling in the client library. The
6475 client must be removed from all channels when receiving the
6478 Also, do not remove the client entry when giving the KILL
6479 command but when the KILLED notify is received.
6481 * Removed silc_idlist_find_client_by_nickname from the server.
6482 Not needed anymore. Affected files silcd/idlist.[ch].
6484 * Implemented the CHANNEL_CHANGE notify type handling to the
6485 server. Affected file silcd/server.c.
6489 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6491 * Added silc_server_send_notify_invite to send the INVITE
6492 notify between routers.
6494 * Implemented the INVITE command correctly to the server.
6496 * Implemented the INVITE notify type handling in the server.
6498 * Implemented the INVITE command to the client library and on the
6501 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Added function silc_server_get_client_resolve to find the
6504 client entry by ID from all ID lists and then resolve it
6505 (using WHOIS) if it cannot be found. Affected file is
6508 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Implemented the BAN command to the client library.
6512 * The JOIN command in the server now checks the invite list
6515 * Changed the silc_command_reply_payload_encode_va and the
6516 silc_command_payload_encode_va to support that if argument is
6517 NULL it ignores and checks the next argument. Affected file
6518 lib/silccore/silccommand.c.
6520 * Added silc_server_send_notify_ban to send the BAN notify
6521 type between routers.
6523 * Chaned the silc_notify_payload_encode to support that if
6524 argument is NULL it ignores and checks the next argument.
6525 Affected file lib/silccore/silcnotify.c.
6527 * Tested ban lists in router environment successfully.
6529 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Implemented BAN command to the server, in silcd/command.[ch].
6533 * Removed the BAN and INVITE_LIST modes from the CMODE command
6536 * Added function silc_string_match to regex match two strings.
6537 Affected files lib/silcutil/silcutil.[ch].
6539 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6541 * Redefined parts of the SilcChannelEntry in the server to support
6542 the new ban and invite lists.
6544 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Redefined the INVITE command. The same command can be used to
6547 invite individuals to the channel but also to manage the invite
6548 list of the channel (to add to and remove from the invite list).
6549 Updated the protocol specs.
6551 * Added new command SILC_COMMAND_BAN that can be used to manage
6552 the ban list of the channel. Updated the protocol specs.
6554 * Removed the channel modes: the SILC_CMODE_BAN and the
6555 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6556 in the CMODE command. The equivalent features are now available
6557 using INVITE and BAN commands. Updated the protocol specs.
6559 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6560 in the network about change in the current ban list. The notify
6561 type is not used by the client.
6563 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6564 support the invite lists.
6566 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Added new function silc_string_regexify that converts string
6569 including wildcard characters into regex string that can
6570 be used by the GNU regex library. Added into the file
6571 lib/silcutil/silcutil.[ch].
6573 Added silc_string_regex_combine to combine to regex strings
6574 into one so that they can be used as one regex string by
6575 the GNU regex library. Added into the file
6576 lib/silcutil/silcutil.[ch].
6578 Added silc_string_regex_match to match two strings. It returns
6579 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6581 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Imported GNU regex to the soruce tree into lib/contrib.
6584 Fixed some compiler warning from the regex.c.
6586 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Fixed MOTD command in the server to work in router environment.
6590 * Fixed the MOTD command in the client library to support
6591 the server argument in the command.
6593 * Added `nickname_len' argument to the silc_idlist_add_client
6594 in the server, as the `nickname' argument may be binary data
6597 * Added silc_idlist_get_channels to return all channels from
6600 * Implemented LIST command to the server. Affected file is
6603 * Implemented the LIST command to the client library and on the
6606 * Added [<user count>] argument to the LIST command reply.
6607 With private channels the user count is not shown.
6609 * Updated TODO and README.
6611 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6613 * The client entry's data.registered must be TRUE even with
6614 global client entry on global client list. The data.registered
6615 is used to check whether the client is anymore in the network,
6616 for example with WHOWAS command so it must be valid.
6618 * Fixed the WHOWAS command in the server. It now actually works
6619 in router environment. Added function into silcd/command_reply.c
6620 silc_server_command_reply_whowas_save.
6622 * Added silc_idlist_purge function to the silcd/idlist.c
6623 to periodically purge the ID Cache.
6625 * Fixed INFO command in the server. It works now in router
6626 environment. Added <server name> argument to the INFO command
6627 reply. Updated the protocol specs.
6629 * Fixed minor bug in silc_idcache_purge to not purge if the
6630 expire value is zero.
6632 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6633 they were buggy because of the WHOWAS information.
6635 * Fixed local command MSG to handle the async resolving of
6636 the remote client properly. It used to fail the first MSG.
6637 Affected file silc/local_command.c.
6639 * Added `data_len' field to SilcIDCache context.
6641 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * Update TODO. Todo in commands in the server.
6645 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6648 used by routers as broadcast packet to inform other routers
6649 about the changed user mode.
6651 Implemented the notify handling in the server. Affected file is
6652 silcd/packet_receive.c. Added the function
6653 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6655 * Added new generic Channel Payload and deprecated the New Channel
6656 Payload. The New Channel Payload is now the generic Channel
6659 * Added new argument `mode' to the silc_server_send_new_channel
6660 as it is required in the Channel Payload now.
6662 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6663 and created a new and real SilChannelPayload to represent the
6664 new generic Channel Payload. Implemented the encode/decode
6665 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6667 * Added silc_server_get_client_channel_list to return the list
6668 of channels the client has joined for WHOIS command reply.
6669 Affected file silcd/server.[ch].
6671 * Implemented the channel list sending in the WHOIS command reply
6672 in server and in the client.
6674 Implemented the channel list displaying on the user interface
6675 as well. Affected file silc/client_ops.c.
6677 * Added silc_channel_payload_parse_list to parse list of Channel
6678 Payloads. It returns SilcDList list of SilcChannelPayloads.
6679 Client for example can use this function to parse the list of
6680 channels it receives in the WHOIS command reply. The caller
6681 must free the list by calling silc_channel_payload_list_free.
6682 Affected files lib/silccore/silcchannel.[ch].
6684 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Added one new argument <user mode> to the WHOIS command reply
6687 to return the mode of the user in SILC. Updated the protocol
6690 Implemented it to the server and client.
6692 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Fixed the mode printing on the user interface on joining.
6695 Affected file silc/client_ops.c.
6697 * Implemented the UMODE command and user modes in general to the
6698 client library and to the user interface.
6700 * Implemented the UMODE command to the server.
6702 * The server now sends UNKNOWN_COMMAND error status if client sends
6703 unknown command. Affected file silcd/command.c.
6705 * All server commands now handle the command identifier the right
6706 way when sending the command reply to the client. The client can
6707 use to identify the command replies with the identifier.
6709 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Added silc_server_get_client_route to resolve the route to
6712 the client indicated by the client ID. Affected file is
6715 * Added silc_server_relay_packet as general function to relay
6716 packet to arbitrary destination. This deprecates functions
6717 like _send_private_message_key, _relay_notify etc. Affected
6718 file is silcd/packet_send.[ch].
6720 Removed silc_server_send_key_agreement,
6721 silc_server_send_private_message_key and
6722 silc_server_packet_relay_notify functions from the file
6723 silcd/packet_send.[ch].
6727 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6728 server. Affected file silcd/packet_receive.[ch].
6730 * Implemented the KILL command to the client. Implemented the
6731 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6732 Affected files lib/silcclient/command[_reply].c and
6733 lib/silcclient/client_notify.c. Implemented the KILL notify
6734 printing in the user inteface.
6736 * Fixed a lot silc_parse_nick memory leaks from the client
6737 library in the file lib/silcclient/command.c.
6739 * Changed the silc_server_send_notify_on_channels's `sender'
6740 argument from SilcSocketConnection to SilcClientEntry to
6741 check the sender as entry and not as connection object and not
6742 to send to the client provided as argument. The affected file
6743 is silcd/packet_send.[ch].
6745 * The notify packets that are destined directly to the client used
6746 to not to be processed by the server. Now changed that and the
6747 server processes all notify packets. After relaying the packet
6748 to the client the notify packet is processed in the server.
6750 * The silc_server_free_client_data now checks whether there is
6751 pending outgoing traffic for the client and purges the data to
6752 the network before removing the client entry.
6754 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6757 an client is killed from the SILC Network. Updated the protocol
6760 Added new function silc_server_send_notify_killed to the
6761 silcd/packet_send.[ch].
6763 * Added function silc_server_packet_relay_notify to relay notify
6764 packets that are destined directly to a client. In this case
6765 the server does not process the notify packets but merely relays
6766 it to the client. Affected file silcd/packet_send.[ch].
6768 Added also silc_server_packet_process_relay_notify to check
6769 whereto relay the notify. Affected file is
6770 silcd/packet_receive.[ch].
6772 * Implemented the KILL command to the server.
6776 * Added the backup schema desgined last fall to the protocol
6777 specs for everyone to see. The specification is in the
6778 *-spec-xx.txt draft and the packet type definitions for the
6779 backup routers is in *-pp-xx.txt draft. Thusly, added also
6780 new packet type SILC_PACKET_CELL_ROUTERS.
6782 * A big security problem in the implementation discovered. The
6783 signoff of an client did not cause new channel key generation
6784 which it of course should've done. The channel keys must be
6785 always re-generated when client leaves (or signoffs) the channel.
6786 The silc_server_remove_from_channels funtion now handles
6787 the channel key re-generation.
6789 * Added `sender' argument to the silc_server_send_notify_on_channels
6790 to not to send the client provided as argument. Affected file
6791 silcd/packet_send.[ch].
6793 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Implemented OPER and SILCOPER commands into the server and
6798 * Added silc_auth_verify and silc_auth_verify_data to verify
6799 the authentication directly from the authentication payload.
6800 It supports verifying both passphrase and public key based
6801 authentication. Affected file lib/silccore/silcauth.[ch].
6803 * Added `hash' field to the SilcIDListData structure. It is the
6804 hash negotiated in the SKE protocol. Affected file is
6807 * Slight redesigning of the SilcAuthPayload handling routines.
6808 Do not send SilcPKCS but SilcPublicKey as argument.
6810 * Implemented the public key authentication support to the
6811 serverconfig. The public key is loaded from the provided path
6812 and saved as authentication data to void * pointer. Thus,
6813 changed the unsigned char *auth_data to void *auth_data;
6815 * Fixed SHUTDOWN command to send the reply before the server
6816 is shutdown. :) Affected file silcd/command.c.
6818 * Fixed fatal bug in CONNECT command. The hostname was invalid
6819 memory and server crashed. Affected file silcd/command.c.
6821 * Fixed fatal bug in CLOSE command. The server_entry became
6822 invalid but was referenced later in the command. Affected file
6825 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Fixed fatal bug in failure packet handling. Server ignored
6828 the failure and thus crashed when it came.
6832 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6835 that the command may be executed only once in (about) 2 seconds.
6836 The old SILC_CF_LAG flag is same but allows command bursts up
6837 to five before limiting.
6839 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6840 server code. Various commands now includes the CF_LAG_STRICT
6841 flag to disallow any kind of miss-use of the command.
6843 * Fixed the silc_buffer_unformat to not to allocate any data
6844 if the length of the data is zero. It used to allocate the
6845 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6847 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Changed the format of AdminConnection configuration section
6850 in the server. Added username of the admin to the format.
6851 Affected files silcd/serverconfig.[ch].
6853 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6854 to return admin configuration data by host, username and/or
6857 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Implemented WHOWAS command to the server. Added the functions:
6861 silc_server_command_whowas_parse,
6862 silc_server_command_whowas_send_reply,
6863 silc_server_command_whowas_from_client and
6864 silc_server_command_whowas_from_server
6866 * Added <Client ID> argument to the WHOWAS command reply. Updated
6867 the protocol specs accordingly.
6869 * Implemented WHOWAS command and command_reply to the client
6872 Implemented the WHOWAS printing on the user interface.
6874 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Added new argument to the WHOWAS command reply, the real name.
6877 It is an optional argument. Updated the protocol specs.
6879 * Added SilcIDCacheDestructor callback that is registered when
6880 the SilcIDCache is allocated. The callback is called when
6881 an cache entry in the ID Cache expires, or is purged from the
6882 cache. Added into lib/silccore/idcache.[ch].
6884 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6885 to destruct the client entries when the cache entry expires.
6886 Other ID Cache's in server and in the client library ignores
6889 * If the ID Cache entry's `expire' field is zero then the entry
6890 never expires. Added boolean `expire' argument to the
6891 silc_idcache_add function in the lib/silccore/idcache.[ch].
6892 If it is TRUE the default expiry value is used.
6894 * Added silc_server_free_client_data_timeout that is registered
6895 when client disconnects. By default for 5 minutes we preserve
6896 the client entry for history - for WHOWAS command.
6898 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Added support to the server to enforce that commands are not
6901 executed more than once in 2 seconds. If server receives
6902 commands from client more frequently, timeout is registered
6903 to process the commands. Affected file silcd/command.c.
6904 Added new function silc_server_command_process_timeout.
6906 * Changed NICK_NOTIFY handling in client library to check that
6907 if the client's nickname was changed, so there is no need to
6908 resolve anything from the server.
6910 * Removed error printing from the WHOIS and IDENTIFY commands.
6911 If error occurs then it is ignored silently in the client library.
6912 The application, however, may map the received error to
6913 human readable error string. The application currently maps
6914 the NO_SUCH_NICKNAME error to string.
6916 * Made the command status message public to the application. Moved
6917 them from lib/silcclient/command_reply.c to
6918 lib/silcclient/command_reply.h. The application can map the
6919 received command status to the string with the
6920 silc_client_command_status_message function.
6922 * Added check to the server to check that client's ID is same
6923 as the Source ID in the packet the client sent. They must
6926 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6928 * Added dist-bzip hook to the Makefile.am to make bzip2
6929 compressed distributions.
6931 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Server now enforces the maximum length for the nickname and
6934 the channel as protocol specification dictates. 128 bytes for
6935 nickname and 256 bytes for channel name.
6937 * Moved the WHOIS printing to the application. The client libary
6938 does not print out the WHOIS information anymore, the application
6939 must do it. Renamed silc_client_command_reply_whois_print to
6940 the silc_client_command_reply_whois_save.
6942 The client's idle time is also sent to the application now, and
6943 the idle is shown on screen.
6945 * Added silc_client_command_reply_identify_save to save the
6946 received IDENTIFY entries.
6948 * Do not check for channel private keys in message sending and
6949 reception if the channel does not have the PRIVKEY mode set.
6950 Affected file lib/silclient/client_channel.c.
6952 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6955 just surfaced after chaning the JOIN procedure.
6957 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Added silc_client_get_clients_by_list to get client entries
6960 from Client ID list, that is returned for example by JOIN
6961 and USERS command replies. The application should use this
6962 function for example when JOIN command reply is received to
6963 resolve the clients already on the channel (library does not
6964 do that anymore as USERS command reply is not used in the JOIN
6965 procedure anymore). Affected files lib/silcclient/silcapi.h and
6966 lib/silcclient/idlist.c.
6968 * JOIN command reply and USERS command reply returns now SilcBuffer
6969 pointers instead of unsigned char pointers when returning
6970 the client list and mode list.
6972 * Added <Client ID> argument to the JOIN command reply, mainly
6973 for the server to identify for which client the command was
6974 originally sent. Updated protocol specs accordingly.
6976 * Added SilcDlist private_key pointer to the SilcChannelEntry
6977 in the client to support the channel private keys. Affected
6978 file is lib/silcclient/idlist.h.
6980 * Added SilcChannelPrivateKey argument to the function
6981 silc_client_send_channel_message so that application can choose
6982 to use specific private ke if it wants to. If it is not provided,
6983 the normal channel key is used, unless private keys are set.
6984 In this case the first (key that was added first) is used
6985 as the encryption key.
6987 * Implemented the support for channel private key handling.
6988 Implemented the following functions:
6990 silc_client_add_channel_private_key,
6991 silc_client_del_channel_private_keys,
6992 silc_client_del_channel_private_key,
6993 silc_client_list_channel_private_keys and
6994 silc_client_free_channel_private_keys
6996 Affected file lib/silcclient/client_channel.c.
6998 * Added the support for the private keys in the channel message
6999 sending and encryption and in the message reception and
7000 decryption. Affected funtions are
7001 silc_client_send_channel_message and silc_client_channel_message.
7003 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Added SKE's key verify callback to the client library's
7006 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7008 * Removed the statement that server (or router) must send USERS
7009 command reply when joining to the channel so that the client
7010 knows who are on the channel. Instead, the client list and
7011 client's mode list is now sent in the JOIN command reply to the
7012 client who joined channel. This is better solution.
7014 * Added function silc_server_get_users_on_channel and function
7015 silc_server_save_users_on_channel to the silcd/server.[ch].
7017 * Removed function silc_server_command_send_users from the
7020 * Do not show topic on the client library anymore. The topic is
7021 sent in the command reply notify to the application and the
7022 application must show the topic now.
7024 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * Added client searching by nickname hash into the IDENTIFY and
7027 WHOIS commands in the server as they were clearly missing from
7028 them. Affected file is silcd/command.c.
7030 * Fixed a bug in private message receiving in the client library.
7031 The remote ID was freed and it wasn't supposed, now it is
7034 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Minor fix to the channel payload; allocate the data area, as it
7037 needs to be of specific length.
7039 * If the key agreement port is zero then the operating
7040 system will define the bound port. Affected files are
7041 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7043 * Added new function silc_channel_payload_decrypt into the file
7044 lib/silccore/silcchannel.[ch].
7046 * Moved the channel message etc, check from silc_packet_decrypt
7047 to applications. The library calls now a generic
7048 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7049 when the packet is either normal or special. This was done to
7050 allow more wide range of checking that was not allowed when
7051 the code was in library. Now applications can do virtually any
7052 checks to the packet and return to the library the decision how
7053 the packet should be processed. Affected files are
7054 lib/silccore/silcpacket.[ch].
7056 Added silc_server_packet_decrypt_check to the server and
7057 silc_client_packet_decrypt_check to the client library.
7059 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7060 to send with specified source and destination information.
7062 * Channel message delivery between routers was broken after the
7063 channel key distribution was fixed earlier. The channel key
7064 was used be to distributed to other routers as well which is not
7065 allowed by the protocol. Now this is fixed and channel keys
7066 really are cell specific and the channel message delivery between
7067 routers comply with the protocol specification.
7069 * Fixed various commands in server to check also the global list
7070 for the channel entry and not just the local list. The affected
7071 file silcd/command.c.
7073 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Added assert()s to buffer formatting and unformatting routines
7076 to assert (if --enable-debug) when error occurs. Affected
7077 file: lib/silcutil/silcbuffmt.c.
7079 * Changed to auto-reconnect to check whether the remote host is
7080 router and register the re-connect timeout if it is. It used
7081 to check that whether we are normal server, but router must do
7082 auto-reconnect with another router as well. Affected file
7085 * Removed the [<key len>] option from CMODE command as the cipher
7086 name decides the key length, nowadays. See the defined ciphers
7087 from the protocol specification.
7089 * Added [<hmac>] option to the CMODE command to define the HMAC
7090 for the channel. Added SILC_CMODE_HMAC channel mode.
7092 * Added [<hmac>] option for the JOIN command so that user can
7093 select which HMAC is used to compute the MACs of the channel
7096 * Added Hmac field to the Channel Message Payload. The integrity
7097 of plaintext channel messages are now protected by computing
7098 MAC of the message and attaching the MAC to the payload. The
7099 MAC is encrypted. Now, it is clear that this causes some
7100 overhead to the size of the packet but rationale for this is that
7101 now the receiver can verify whether the channel message decrypted
7102 correctly and also when private keys are set for the channel the
7103 receiver can decrypt the packet with several keys and check from
7104 the MAC which key decrypted the message correctly.
7106 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7107 lib/silccrypt/silccipher.[ch].
7109 * Added silc_hash_len to return the digest length into the
7110 lib/silcrypt/silchash.[ch].
7112 * Rewrote parts of Silc Channel Payload interface in the
7113 lib/silccore/silcchannel.[ch]. The encode function now also
7114 encrypts the packet and parse function decrypts it.
7116 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Fixed a minor formatting bug in the SKE's key material processing.
7119 It actually might have processed the keys wrong way resulting
7122 * Redefined the mandatory HMAC algorithms and added new algorithms.
7123 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7124 and hmac-md5 truncated to 96 bits. The mandatory is now
7125 hmac-sha1-96. Rest are optional (including the one that used
7126 to be mandatory). Rationale for this is that the truncated HMAC
7127 length is sufficient from security point of view and can actually
7128 make the attack against the HMAC harder. Also, the truncated
7129 HMAC causes less overhead to the packets. See the RFC2104 for
7132 * Added new [hmac] configuration section. The SKE used to use
7133 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7134 is of course wrong. The official names that must be proposed in
7135 the SKE are the ones defined in the protocol specification
7136 (hmac-sha1-96 for example). The user can configure any hmac
7137 using any hash function configured in the [hash] section. At
7138 least, the mandatory must be configured.
7140 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7142 * Added HMAC list to the SKE proposal list. It has now both
7143 hash algorithm list and HMAC list. This makes the protocol
7144 incompatible with previous versions. The SKE now seems to work
7145 the way it is supposed to work, for the first time actually.
7147 * Defined plain Hash algorithms to the protocol specification.
7150 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Implemented support for key agreement packets into the server.
7153 Added functions silc_server_key_agreement and
7154 silc_server_send_key_agreement. Other than these functions,
7155 server has nothing to do with this packet.
7157 * Added support for private message key packets into the server.
7158 Added functions silc_server_private_message_key and
7159 silc_server_send_private_message_key.
7163 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7164 called in the protocol's final callback instead in the END
7165 protocol state. This makes a little more sense and in the same
7166 time in client we can use the same protocol routines for normal
7167 key exchange and to key agreement packet handling as well.
7169 * Added to both client's and server's KE protocol context the
7170 SilcSKEKeyMaterial pointer to save the key material. We will
7171 bring the key material to the protocol's final callback by doing
7172 this. The final callback must free the key material.
7174 * Added SKE's packet_send callback into client's KE protocol
7175 context so that the caller can choose what packet sending function
7176 is used. This way we can use different packet sending when
7177 doing normal SKE when doing key agreement packet handling (in
7178 the key agreement packet handling we do not want to encrypt
7181 * Implemented the responder side of the key agreement routines
7182 in the client. The client can now bind to specified port and
7183 accept incoming key negotiation. The key material is passed
7184 to the application after the protocol is over.
7186 * Implemented the processing of incoming Key Agreement packet
7187 in the client. Added function silc_client_key_agreement to
7190 * Implemented the intiator side of the key agreement routines
7191 in the client. The client can now initiate key agreement with
7192 another remote client. The key material is passed to the
7193 application after the protocol is over.
7195 * Created client_keyagr.c to include all the key agreement
7198 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7199 SILC_TASK_CALLBACK except that it is not static.
7201 * Created client_notify.c and moved the Notify packet handling
7202 from the client.[ch] into that file.
7204 * Created client_prvmsg.c and moved all private message and
7205 private message key routines from the client.[ch] into that file.
7207 * Create client_channel.c and moved all channel message and
7208 channel private key routines from the client.[ch] into that file.
7210 * Changed silc_client_get_client_by_id_resolve to resolve with
7211 WHOIS command instead of IDENTIFY command, in the file
7212 lib/silclient/idlist.c.
7214 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Implemented the SKE's responder side to the Client library.
7218 * When FAILURE is received to the protocol do not trust it
7219 blindly. Register a timeout to wait whether the remote closes
7220 the connection as it should do it, only after that process the
7221 actual failure. This was changed to both client and server.
7223 * Added client_internal.h to include some of the structures
7224 there instead of client.h in lib/silcclient/.
7226 * Added function silc_task_unregister_by_callback to unregister
7227 timeouts by the callback function.
7229 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7231 * Some "Incomplete WHOIS info" errors has been appearing on the
7232 log files. Took away the entry->userinfo check from WHOIS
7233 reply sending. The entry->userinfo is now " " if client did not
7234 provide one. I thought this was fixed earlier but something
7235 is wrong still. Let's see if the error still appears.
7237 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Fixed a minor bug in the login when the channel key is
7240 re-generated in the server. It used to generate the key in
7241 wrong order and thus caused problems in the channel traffic.
7243 * Fixed a minor bug in channel key distsribution after
7244 KICK command. The key was not sent to the router even though
7247 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7249 * Added silc_ske_process_key_material_data as generic routine
7250 to process any key material as the SILC protocol dictates. The
7251 function is used by the actual SKE library but can be used by
7252 applications as well. This relates to the private message keys
7253 and the channel private keys since they must be processed the
7254 same way the normal SILC session keys. The protocol dictates
7255 this. Affected files: lib/silcske/silcske.[ch].
7257 Added also silc_ske_free_key_material to free the
7258 SilcSKEKeyMaterial structure.
7260 * Defined silc_cipher_set_key function to set the key for
7261 cipher without using the object's method function. The affected
7262 files: lib/silccrypt/silccipher.[ch].
7264 * Implemented silc silc_client_add_private_message_key,
7265 silc_client_add_private_message_key_ske,
7266 silc_client_del_private_message_key,
7267 silc_client_list_private_message_keys and
7268 silc_client_free_private_message_keys functions in the
7271 Added functions silc_client_send_private_message_key to send
7272 the Private Message Key payload and silc_client_private_message_key
7273 to handle incoming Private Message Key payload.
7275 * Added Cipher field to the Private Message Key payload to set
7276 the cipher to be used. If ignored, the default cipher defined
7277 in the SILC protocol (aes-256-cbc) is used.
7279 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Removed lib/silcclient/ops.h file.
7283 Redefined parts of the SILC Client Library API. Created new
7284 file silcapi.h that deprecates the ops.h file and defines the
7285 published Client Library API. Defined also private message key
7286 API and channel private key API into the file.
7288 This is the file that the application must include from the
7289 SILC Client Library. Other files need not be included by
7290 the application anymore.
7292 * Added new key_agreement client operation callback and also
7293 defined the Key Agreement library API for the application.
7295 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7297 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7298 is used by clients to request key negotiation between another
7299 client in the SILC network. If the negotiation is started it
7300 is performed using the SKE protocol. The result of the
7301 negotiation, the secret key material, can be used for example
7302 as private message key.
7304 Implemented the Key Agreement payload into the files
7305 lib/silccore/silauth.[ch].
7307 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Redefined ciphers for the SILC protocol. Added some new ciphers
7310 and defined the key lengths for the algorithms. Changed the
7311 code accordingly. The default key length is now 256 bits.
7313 * Fixed SKE key distribution function silc_ske_process_key_material
7314 when the key length is more than 128 bits. The default key
7315 length in SILC is now 256 bits.
7317 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7318 to indicate unsupported algorithm.
7320 * Renamed rijndael.c to aes.c and all functions as well.
7322 * Fixed a long standing channel key setting bug in client library.
7323 Weird that it has never surfaced before.
7325 * Fixed bug in channel deletion. If the entire channel is removed
7326 then it must also delete the references of the channel entry
7327 from the client's channel list as the client's channel entry and
7328 the channel's client entry share same memory.
7330 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Implemented CONNECT and SHUTDOWN commands in the client.
7334 * Implemented CLOSE command to the client.
7336 * Added the function silc_idlist_find_server_by_name into the
7337 files silcd/idlist.[ch].
7339 Added the function silc_idlist_find_server_by_conn into the
7340 files silcd/idlist.[ch].
7342 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7344 * DIE command was renamed to SHUTDOWN. Updated the both code
7347 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7348 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7350 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7353 * Added function silc_server_create_connection function to create
7354 connection to remote router. My server implementation actually
7355 does not allow router to connect to normal server (it expects
7356 that normal server always initiates the connection to the router)
7357 so the CONNECT command is only good for connecting to another
7360 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7362 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7363 or some other client was kicked from the channel.
7365 Implemented the handling of the notify type to both client
7368 Implemented silc_server_send_notify_kicked to send the KICKED
7369 notify. It is used to send it to the server's primary router.
7371 * Implemented the KICK command into server and client.
7373 * Added `query' argument to the silc_idlist_get_client function
7374 to indicate whether to query the client from server or not if
7377 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7378 to indicate that the client is not channel founder.
7382 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7384 * Removed the rng context from SilcPacketContext structure and
7385 changed that the packet routine uses the Global RNG API.
7387 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Added support for quit message that client can "leave" on the
7390 channel when it quits the SILC. It is ditributed inside the
7391 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7393 Added silc_server_free_client_data that will take the
7394 signoff message as argument.
7396 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7398 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7400 * Updated parts of the protocol specification to keep it up
7403 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7406 payloads in one packet.
7408 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7409 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7410 use now the new List flag.
7412 * Also deprecated the following packet types: REPLACE_ID,
7413 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7415 * Added list support for Notify packet in server.
7417 * Added silc_server_send_notify_channel_change to send the
7418 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7419 the silc_server_send_replace_id.
7421 * Added silc_server_send_notify_nick_change to send the
7422 NICK_CHANGE notify type. Deprecates the function
7423 silc_server_send_replace_id.
7425 * Added silc_server_send_notify_join to send the JOIN notify type.
7426 Deprecates the function silc_server_send_new_channel_user.
7428 * Added silc_server_send_notify_leave to send LEAVE notify type.
7429 Deprecates the function silc_server_send_remove_channel_user.
7431 * Added silc_server_send_notify_cmode and
7432 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7433 types. Deprecates the silc_server_send_set_mode function.
7435 * Added SERVER_SIGNOFF notify type to indicate that server has
7436 quit. This means that all clients on the channel from that
7437 server will drop. This can be also used when netsplit happens.
7439 Deprecated REMOVE_ID packet type since it is not needed anymore
7442 Added silc_server_send_notify_server_signoff to send the
7443 SERVER_SIGNOFF notify type. Deprecates the function
7444 silc_server_send_remove_id.
7446 Added also silc_server_send_notify_signoff to send the
7447 SIGNOFF notify type.
7449 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7450 SILC protocol from this day on. Changed the protocol
7451 specification as well.
7453 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7454 notify type. It is used between routers to notify about
7455 topic changes on a channel.
7457 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7460 * Partly updated the protocol specification to comply with the
7461 changes now made. It is still though a bit outdated.
7463 * The JOIN notify type now takes one extra argument <Channel ID>.
7464 The packet used to be destined to the channel but now the
7465 JOIN type may be sent as list thus it is impossible to
7466 destine it to any specific channel. By adding this argument
7467 it is again possible.
7469 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7471 * Added CREDITS file. The CHANGES and CREDITS file will appear
7472 in the distribution as well.
7474 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7476 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7477 types in the server's silcd/packet_receive.c.
7479 * Implemented CMODE and CUMODE to work in router environment.
7481 * Fixed minor encoding and decoding buglet from the
7482 lib/silccore/silcmode.c.
7484 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7487 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7489 * Changed all SilcConfigServer* and silc_config_server* to
7490 SilcServerConfig* and silc_server_config*, respectively.
7493 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Associated the ID (client or server ID) to the Authentication
7496 Payload to avoid any possibility of forging. Updated the
7497 protocol specification and the code accordingly.
7499 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7501 * The RSA key length is now save to the RsaKey context in the
7502 key generation process in lib/silccrypt/rsa.c. The key length
7503 is now used to figure out the maximum size of the block allowed
7504 to be encrypted/signed.
7506 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7507 is equivalent to the silc_mp_mp2bin but does not allocate any
7510 * Changed silc_mp_mp2bin API to take length argument. If it is
7511 non-zero then the buffer is allocated that large. If zero, then
7512 the size is approximated using silc_mp_sizeinbase, which however
7515 * Created Global RNG API which is global RNG that application can
7516 initialize. After initializing, any routine anywhere in the
7517 code (including library) can use RNG without allocating a new
7518 RNG object. This was done to allow this sort of use of the
7519 RNG in code that has no chance to allocate RNG object. All
7520 applications currently allocate this and many routines in the
7521 library use this. Affected file lib/silccrypt/silcrng.[ch].
7523 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7524 it to use the Global RNG API.
7526 * Defined Authentication Payload into protocol specification that
7527 is used during SILC session to authenticate entities. It is
7528 used for example by client to authenticate itself to the server
7529 to obtain server operator privileges.
7531 Implemented this payload into the lib/silccore/silcauth.[ch].
7532 Implemented also routines for public key based authentication
7533 as the new protocol specification dictates.
7535 Moved definitions of different authentication methods from
7536 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7538 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7539 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7540 silc_pkcs_verify_with_hash functions into the file
7541 lib/silccrypt/silcpkcs.[ch].
7543 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7545 * The client entry's userinfo pointer must be always valid.
7546 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7547 will fail since it requires the userinfo. Now, the userinfo
7548 is allocated as "" if actual userinfo does not exist. Actually,
7549 it must exist and it is totally Ok to drop client connections
7550 that does not announce the userinfo. However, we will make
7551 this workaround for now.
7553 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7554 to return the remote port by socket.
7556 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7558 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7559 SILC_SERVER_PENDING_EXEC and added an new macro
7560 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7561 data or when error occurs while processing the pending command.
7563 Added new argument `destructor' into silc_server_command_pending
7564 and to the SilcServerCommandPending object. This destructor is
7565 now called after calling the pending callback or if error occurs
7566 immediately. If error occurs the actual pending callback won't
7567 be called at all - only the destructor. The destructor may be
7568 NULL if destructor is not needed.
7570 All this applies for client library code as well. Similar
7571 changes were made there as well for the pending commands.
7573 In the client, the application must now allocate the
7574 SilcClientCommandContext with the silc_client_command_alloc
7577 * Added reference counter to the SilcServerCommandContext. Added
7578 function silc_server_command_alloc and silc_server_command_dup
7581 Same type of functions added to the client library for the same
7584 * Removed the cmd_ident from IDListData away since it is now
7585 global for all connections. It is the command identifier used
7586 in command sending and with pending commands. The affected file
7589 * Added reference counter to the SilcSocketConnection objecet to
7590 indicate the usage count of the object. The object won't be
7591 freed untill the reference counter hits zero. Currently only
7592 server uses this, and client ignores it. The client must be
7593 set to use this too later. The affected files are
7594 lib/silccore/silcsockconn.[ch]. Added also the function
7595 silc_socket_dup to increase the reference counter.
7597 This was mainly added because it is possible that the socket
7598 is removed underneath of pending command or other async
7599 operation. Now it won't be free'd and proper DISCONNECTING
7600 flags, etc. can be set to avoid sending data to connection that
7601 is not valid anymore.
7603 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7604 the connection. After that it sets SILC_SET_DISCONNECTED.
7605 It is, however, possible that the socket data is not still freed.
7606 The silc_server_packet_process now checks that data is not
7607 read or written to connection that is DISCONNECTED. The socket
7608 get's freed when the reference counter hits zero.
7610 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Changed the client operation API: channel_message operation's
7613 `sender' is now the client entry of the sender, not the nickname
7614 and the `channel' is the channel entry, not the channel name.
7616 In the private_message operation the `sender' is now also the
7617 client entry of the sender not the nickname.
7619 Affected file is lib/silcclient/ops.h and all applications
7620 using the client operations.
7622 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Moved the calling of ops->connect() from connect_to_server_final
7625 into receive_new_id functin since that is the point when the
7626 client is actually allowed to send traffic to network. The
7627 affected file is lib/silcclient/client.c.
7629 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7631 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7632 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7633 (if needs broadcasting) instead of broadcasting the packets one
7634 by one which would make a burst in the network traffic.
7636 * Added `broadcast' argument to the functions in silcd/server.[ch]
7637 silc_server_create_new_channel[_with_id] to indicate whether
7638 to send New Channel packet to primary router.
7640 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Added new function into the silcd/server.[ch] files:
7643 silc_server_create_new_channel_with_id to create new channel with
7644 already existing Channel ID.
7646 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7647 lib/silccore/silcpacket.h. This packet is used t send list of
7648 Set Mode payloads inside one packet. Server uses this to set
7649 the modes for the channels and clients on those channels, that it
7650 announced to the router when it connected to it. The protocol
7651 specification has been updated accordingly.
7653 * The silc_server_new_channel did not handle the packet coming
7654 from normal server as it normally does not send that. However,
7655 when it announces its channels it does send it. Implemented
7656 the support for that.
7658 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7659 into the file lib/silccore/id.h.
7661 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7663 * Fixed memory leaks in the functions silc_idlist_del_client,
7664 silc_idlist_del_channel and silc_idlist_del_server in the file
7665 silcd/idlist.c. All of those leaked like a sieve.
7667 * Fixed some small memory leaks in the client's function
7668 silc_client_notify_by_server.
7670 * Added functions into silcd/server.c: silc_server_announce_clients,
7671 silc_server_announce_channels and silc_server_announce_server.
7672 These functions are used by normal and router server to announce
7673 to its primary router about clients, channels and servers (when
7674 router) that we own. This is done after we've connected to the
7677 These functions effectively implements the following packet types:
7678 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7679 and SILC_PACKET_NEW_ID_LIST.
7681 * Added new functions into the silcd/packet_receive.[ch]:
7682 silc_server_new_id_list, silc_server_new_channel_list and
7683 silc_server_new_channel_user_list to handle the incoming
7684 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7686 * Added support of changing Channel ID in the function
7687 silc_server_replace_id. If the server that announces a channel
7688 to the router already exists in the router (with same name but
7689 with different Channel ID), router is responsible to send
7690 Replace ID packet to the server and force the server to change
7691 the Channel ID to the one router has.
7693 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7694 client that the Channel ID has been changed by the router. The
7695 normal server sends this to the client. Client must start using
7696 the new Channel ID as the channel's ID.
7698 Implemented handling of this new type into lib/silcclient/client.c
7699 into the function silc_client_notify_by_server.
7701 * Added new function silc_idlist_replace_channel_id into the files
7702 silcd/idlist.[ch] to replace the Channel ID.
7704 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7706 * Call silc_server_command_identify_check always when processing
7707 the IDENTIFY command in silcd/command.c
7709 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7712 send keepalive packets. The packet can be sent by clients,
7713 servers and routers.
7715 Added function silc_socket_set_heartbeat into the file
7716 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7717 If not set, the heartbeat is not performed. The actual
7718 heartbeat is implemented in the low level socket connection
7719 library. However, application is responsible of actually
7722 Added silc_server_send_heartbeat to send the actual heartbeat
7723 packet into silcd/packet_send.[ch]. Server now performs
7724 keepalive with all connections.
7726 * Added silc_task_get_first function into lib/silcutil/silctask.c
7727 to return the timeout task with shortest timeout. There was a bug
7728 in task unregistration that caused problems. TODO has been
7729 updated to include that task system must be rewritten.
7731 * The client library will now resolve the client information when
7732 receiving JOIN notify from server for client that we know but
7733 have incomplete information.
7735 * Rewrote parts of silc_server_remove_from_channels and
7736 silc_server_remove_from_one_channel as they did not remove the
7737 channel in some circumstances even though they should've.
7739 * Encryption problem encountered in server:
7741 The LEAVE command used to send the Channel Key packet to the
7742 router immediately after generating it. However, the code
7743 had earlier sent Remove Channel user packet but not immediately,
7744 ie. it was put to queue. The order of packets in the router
7745 was that Channel Key packet was first and Remove Channel User
7746 packet was second, even though they were encrypted in the
7747 reverse order. For this reason, MAC check failed. Now, this
7748 is fixed by not sending the Channel Key packet immediately but
7749 putting it to queue. However, this is more fundamental problem:
7750 packets that are in queue should actually not be encrypted
7751 because packets that are sent immediately gets encrypted
7752 actually with wrong IV (and thus MAC check fails). So, packets
7753 that are in queue should be encrypted when they are sent to
7754 the wire and not when they put to the queue.
7756 However, the problem is that the current system has not been
7757 designed to work that way. Instead, the packet is encrypted
7758 as soon as possible and left to the queue. The queue is then
7759 just purged into wire. There won't be any fixes for this
7760 any time soon. So, the current semantic for packet sending
7763 o If you send packet to remote host and do not force the send
7764 (the packet will be in queue) then all subsequent packets to the
7765 same remote host must also be put to the queue. Only after the
7766 queue has been purged is it safe again to force the packet
7769 o If you send all packets immediately then it safe to send
7770 any of subsequent packets through the queue, however, after
7771 the first packet is put to queue then any subsequent packets
7772 must also be put to the queue.
7774 Follow these rules and everything works fine.
7776 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Added new function silc_server_remove_clients_by_server to
7779 remove all client entries from ID list when the server connection
7780 is lost. In this case it is also important to invalidate all
7781 client entires as they hold the invalid server entry. This
7782 fixes fatal bug when server has lost connection and will reconnect
7785 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * Made some sanity checks to silc_server_daemonise like to check
7788 whether the requested user and group actually exists.
7790 * Added sanity check to SKE's silc_ske_responder_finish to check
7791 that the public and private key actually is valid.
7793 * Invalidate the client's nickname when receiving Replace ID
7794 packet and the Client ID is being replaced. This means that the
7795 server will query the nickname if someone needs it (client)
7798 * Sort the ID Cache in client library when the ID Cache data
7799 has changed (needs sorting).
7801 * Do not allow for SILC client to create several connections to
7802 several servers. The client does not support windows right now
7803 and generating multiple connections causes weird behaviour.
7805 Irssi-silc client does support windows and can handle several
7806 connections without problems, see: www.irssi.org and SILC plugin.
7808 * Fixed some places where client was added to the IDList. The
7809 rule of thumb is following (in order to get everything right):
7810 If the client is directly connected local client then the
7811 `connection' argument must be set and `router' argument must be
7812 NULL to silc_idlist_add_client function. If the client is not
7813 directly connected client then the `router' argument must
7814 bet set and the `connection' argument must be NULL to the
7815 silc_idlist_add_client function.
7817 * The funtion silc_server_packet_send_local_channel actually did
7818 not check whether the client was locally connected or not. It
7819 does that now. Fixed a bug related to LEAVE command.
7821 * Fixed Remove Channel User payload parsing bug in server's
7822 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7824 * The server's silc_server_save_channel_key now checks also the
7825 global ID list for the channel as it might not be in the local
7826 list. Fixed a bug related to LEAVE command.
7828 * Is this the end of the [<unknown>] buglet that has been lurking
7829 around for a long time? A little for loop fix in server's
7830 silc_server_command_whois_parse that is used by both IDENTIFY
7831 and WHOIS command. At least, this was a clear bug and a cause
7832 of one type of [<unknown>] buglet.
7834 * WHOIS and IDENTIFY commands call the function
7835 silc_server_command_[whois/identify]_check function even if
7836 we are not router server.
7838 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * Added --with-gmp configuration option. If set the GMP
7841 is always compiled in the SILC source tree. If not set then
7842 it is checked whether the system has the GMP3 installed. If
7843 it has then the GMP won't be compiled (the system's headers
7844 and library is used), if it doesn't have it then the GMP is
7845 compiled in the SILC source tree.
7847 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7849 * Changed RSA private exponent generation to what PKCS #1
7850 suggests. We try to find the smallest possible d by doing
7851 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7852 not security fix but optimization.
7854 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Added new config entry [Identity] to fork the server and run
7857 it as specific user and group. A patch from Bostik.
7859 * Imported Dotconf configuration library into lib/dotconf.
7860 This will be used to create the SILC configuration files later.
7861 It will appear in the distsribution after this commit.
7863 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7865 * A big code auditing weekend happening. Auditing code for
7866 obvious mistakes, bugs and errors. Also, removing any code
7869 Removed files for being obsolete:
7871 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7872 inline in the file lib/silcutil/silcbuffer.h)
7874 o lib/silcutil/silcbufutil.c (the header has inline versions)
7876 Changed code to fix possible error conditions:
7878 o The buffer formatting routines now check that the destination
7879 buffer really has enough space to add the data. This applies for
7880 both buffer formatting and unformatting
7881 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7882 unformatting was changed to accomodate following rules:
7883 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7884 sent to the function while XXX_*STRING will not allocate or copy
7885 the data into the buffer. Instead it sets the pointer from the
7886 buffer into the pointer sent as argument (XXX_*STRING used to
7887 require that the pointer must be allocated already). This change
7888 makes this whole thing a bit more consistent and more optimized
7889 (note that the data returned in the unformatting with XXX_*STRING
7890 must not be freed now). The routines return now -1 on error.
7892 o Tried to find all code that use buffer_format and buffer_unformat
7893 and added return value checking to prevent formatting and
7894 especially unformatting errors and possible subsequent fatal
7897 o Changed ske->x and ske->KEY to mallocated pointers in
7898 lib/silcske/silcske.h. Fixed possible data and memory leak.
7900 o Added return value checking to all *_parse* functions. Fixed
7901 many memory leaks as well.
7903 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7904 so that buffer overflows would not happen. All code now also
7905 checks the return value as it can fail.
7907 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7909 * Added reconnection support to server if the normal server looses
7910 its connection to the router (for example if router is rebooted).
7911 The server performs normal reconnection strategy implemented
7912 to the server. Affected file silcd/server.c.
7914 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7916 * Added new packet type SILC_PACKET_SET_MODE that is used to
7917 distribute the information about changed modes (for clients,
7918 channels and clients channel modes) to all routers in the
7919 network. Updated the protocol specification accordingly.
7921 Added functions into silcd/packet_send.c and
7922 silcd/packet_receive.c: silc_server_send_set_mode,
7923 silc_server_set_mode.
7925 Added new files silcmode.[ch] into lib/silccore that implements
7926 the encoding and decoding of Set Mode Payload. Added new type
7927 SilcSetModePayload. Moved the definitions of different modes
7928 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7930 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7932 * Oops, a little mistake in server's connection authentication
7933 protocol. The protocol is not ended with FAILURE but with
7934 SUCCESS if the authentication is Ok. :) Affected file is
7937 * Implemented NICK_CHANGE notify handling in server in the file
7938 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7939 the local clients on the channel. After the changing nickname
7940 in router environment snhould work and the [<unknown>] nickname
7941 should appear no more.
7943 The silc_server_replace_id function that receives the Replace ID
7944 payload now sends the NICK_CHANGE notify type also in the file
7945 silcd/packet_receive.c
7947 * Changed WHOIS and IDENTIFY command to support the maximum amount
7948 of arguments defined in protocol specs (3328 arguments). This
7949 fixed a bug that caused problems when there were more than three
7952 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7954 * Added extra parameter, command identifier, to the
7955 silc_client_send_command so that explicit command identifier
7958 Changed that ID list routines uses specific command identifier
7959 when sending WHOIS/IDENTIFY requests to the server so that they
7960 can be identified when the reply comes back.
7962 Affected files lib/silcclient/command.[ch],
7963 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7965 * Added `sender' argument to silc_server_packet_send_to_channel
7966 to indicaet the sender who originally sent the packet to us
7967 that we are now re-sending. Ignored if NULL. Affected file
7968 silcd/packet_send.[ch].
7970 * Added some server statistics support in silcd/server_internal.h
7971 SilcServerStatistics structure and around the server code. Also
7972 send some nice statistics information when client is connecting
7975 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Fixed channel ID decoding in server's JOIN command reply in
7978 silcd/command_reply.c
7980 * Fixed braodcasting of replace ID payload to not to send it if
7981 we are standalone server in silcd/packet_receive.c.
7983 * Fixed all channel message sending routines to not to send
7984 packets to clients that has router set, since they are routed
7985 separately in the same function earlier. Affects file
7986 silcd/packet_send.c and all channel packet sending functions.
7988 * In USERS reply, res_argv[i] are not allocated, the table
7989 is allocated. Thus changed that free the table, not its
7992 * In server's whois_check and identify_check if the client is
7993 locally connected do not send any WHOIS commands - they are not
7996 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7998 * Fixed some minor bugs in client when sending WHOIS command. The
7999 arguments was in wrong order.
8001 * Removed statis function add_to_channel from server in
8002 silcd/command.c that was previously used with the joining but
8005 * Tested USERS command in router environment successfully with two
8006 routers, two servers and two clients.
8008 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8010 * Reorganized the USERS command and command reply in client library
8011 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8012 When the command is given by user we register a pending command
8013 callback that will reprocess the command after the reply has been
8014 received from the server. When reprocessing the packet we then
8015 display the information. Thus, the USERS information is displayed
8016 now in the command callback instead of in the command reply
8017 callback. The processing of the command is same as previously
8018 when server has sent the command reply in the JOINing process.
8020 * Added to USERS command in silcd/command_reply.c to join the client,
8021 we didn't use to know about, to the channel after we've created
8022 a client entry for it. Also, for clienet we did know already still
8023 check whether it is on the channel or not and add it if not.
8025 * Removed silc_server_command_join_notify as the function and its
8028 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8030 * Changed the client's pending command handling to the same as the
8031 server's pending command handling. It is also now possible to
8032 execute command reply functions from other command reply
8033 function as the function callbacks for commands and command
8034 replies are one and same. The pending commands are not static
8035 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8036 in client connection context. Thus, pending commands are server
8037 connection specific as it is convenient.
8039 Changed the function silc_client_command_pending and
8040 silc_client_command_pending_del and added new function
8041 silc_client_command_pending_check. Removed the
8042 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8045 * Added cmd_ident, current command identifier, to the client
8046 connection context in lib/silcclient/client.h to keep track on
8047 command identifiers used in command sending. Client's command reply
8048 function handling now supports the mandatory command identifiers.
8050 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8051 funtions in client to fully support pending command callbacks.
8053 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8054 as one of the arguments to the application in the command reply
8057 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8058 before first releasing SILC but came back. Now it is removed again
8059 and should come back nomore. The FORWARDED flag was used only
8060 by the JOINing procedure by forwarding the command packet to router.
8061 Now, the JOINing procedure has been changed to more generic (due
8062 to various router environment issues) and FORWARDED is not needed
8063 anymore for anything. The protocol specification is yet to be
8066 Now, removed silc_server_packet_forward from server and the flag
8067 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8069 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8071 * Renamed NAMES command to USERS command. The NAMES was named that
8072 due to historical reasons. Now it is renamed. Also, rewrote
8073 parts of the USERS command. The nickname list is not sent anymore
8074 by the server. Only Client ID and mode lists are sent in the USERS
8075 command. Changed this also to the protocol specification.
8077 The client now resolves the names and stuff after it receives
8078 the USERS list from the server when joining to the channel.
8080 * WHOIS and IDENTIFY commands has been changed to support multiple
8081 Client ID's per command. One can now search for multiple users
8082 in the network by sending only one WHOIS or IDENTIFY command.
8083 Changed the code and the protocol specifications.
8085 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8086 uses silc_server_command_whois_parse to parse the request. */
8088 * If normal server, do not parse the WHOIS and IDENTIFY requests
8089 before sending it to the router. Saves some time.
8091 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8093 * Fixed JOIN command on client library. Wrong number of arguments
8094 used to crash the client.
8096 * Added silc_server_channel_has_global function to check whether
8097 channel has global users or not.
8099 * Added silc_server_channel_has_local function to check whether channel
8100 has locally connected clients on the channel.
8102 * The silc_server_remove_from_one_channel now checks whether the
8103 channel has global users or not after given client was removed from
8104 the channel. It also checks whether the channel has local clients
8105 on the channel anymore. If it does not have then the channel entry
8106 is removed as it is not needed anymore.
8108 * The silc_server_notify now checks on JOIN notify whether the joining
8109 client is one of locally connected or global. If it is global then
8110 the channel has now global users on the channel and that is marked
8111 to the channel entry. Also, it now saves the global client to
8112 global list who is joining and JOINs it to the channel. This is
8113 for normal server, that is.
8115 Changed silc_server_send_notify_on_channel,
8116 silc_server_packet_relay_to_channel and
8117 silc_server_packet_send_to_channel check if we are normal server
8118 and client has router set (ie. global client) do not send the
8119 message to that client, as it is already routed to our router.
8121 * Implemented LEAVE notify type handling in silc_server_notify
8124 * Tested LEAVE command in router environment successfully. Tested
8125 with two routers, two servers and two clients.
8129 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8131 * Implemented SIGNOFF notify type handling in silc_server_notify
8134 * silc_server_remove_id now removes the client entry from all channels
8135 it has joined and thusly sends SIGNOFF notify type.
8137 * Rewrote the NAMES list generation in server by removing two excess
8138 loops. The lists are created now inside one loop.
8140 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8142 * silc_server_remove_channel_user checks now also global list
8143 for channel and client.
8145 * silc_server_new_channel_user checks now both local and global
8146 list for channel and client. Fixed a bug in client id decoding.
8147 Used to decode wrong buffer.
8149 * silc_server_channel_message checks now both local and global
8150 list for channel entry.
8152 * Tested channel joining (hence JOIN) in router environment
8153 successfully. Tested with two routers, two servers and two
8156 * Tested channel message sending in router environment successfully.
8158 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8160 * Added silc_server_save_channel_key into server.[ch] to save the
8161 received channel key in Channel Key payload processing. It is
8162 also used in JOIN command reply handling.
8164 Equivalent function silc_client_save_channel_key added into
8165 client.[ch] into client library.
8167 * Changed JOIN command reply to send information whether the channel
8168 was created or not (is existing already) and the channel key
8169 payload. Changed protocol specs accordingly.
8171 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8172 the request was sent by ID and not by nickname. Crashed on
8175 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8177 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8178 now correctly save the received data.
8180 * silc_server_free_sock_user_data now notifies routers in the
8181 network about entities leaving the network.
8183 At the same time implemented functions silc_server_remove_id
8184 and silc_server_send_remove_id to receive and send REMOVE_ID
8185 packets. The packet is used to notify routers in the network
8186 about leaving entities. The ID removed will become invalid in
8189 * Added function silc_idlist_del_server into server. Removes and
8190 free's server entry from ID list.
8192 * silc_server_private_message function now checks, if we are router,
8193 that the destination ID really is valid ID, naturally.
8195 * In router when NEW_ID packet is received (for new client) the
8196 hash of the Client ID is saved in the ID Cache but the
8197 client->nickname is set to NULL, instead of putting the hash
8200 IDENTIFY command now also checks that client->nickname must be
8201 valid. If it is not if will request the data from the server who
8202 owns the client. Added new function
8203 silc_server_command_identify_check.
8205 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8206 to set the command to already allocated Command Payload.
8208 * Tested private message sending in router environment with two
8209 routers, two servers and two clients. Fixed minor bugs and now
8212 * Fixed segfault from client's NAMES command. Used to crash if
8215 * Forwarded packets must not be routed even if it is not destined
8216 to the receiver. Changed server code comply with this.
8218 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8220 * Added `require_reverse_mapping' boolean value to ServerParams
8221 structure. If TRUE (not default) the server will require that
8222 the connecting host has fully qualified domain name.
8224 If the reverse mapping is not required and hostname could not be
8225 found the IP address is used as hostname.
8227 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8229 * Implemented version string checking to both client and server.
8230 The check is incomplete currently due to the abnormal version
8231 strings used in development version of SILC.
8233 * Changed all command functions in server to use the new
8236 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8238 * Changed char *data to unsigned char *data in ID Cache system to
8239 support binary data as ID Cache data. Changed code to support
8240 binary data in lib/silccore/idcache.c.
8242 * Renamed silc_server_packet_relay_command_reply to
8243 silc_server_command_reply as it is normal packet receiving
8244 function. Rewrote the function to accept command replys for
8245 servers and not only for clients.
8247 * Mark remote router always as registered server if we are connecting
8248 to it. Otherwise, commands sent by the router to us are ignored.
8250 * All ID List find routines now returns the ID Cache Entry pointer
8251 as well if requested.
8253 * WHOIS command works now in router environment, tested with two
8254 routers, two servers and two clients.
8256 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8257 in router environment (as it is almost equivalent to WHOIS) but
8258 hasn't been tested thoroughly. Added new functions:
8260 silc_server_command_identify_parse
8261 silc_server_command_identify_send_reply
8262 silc_server_command_identify_from_client
8263 silc_server_command_identify_from_server
8265 * Disabled route cache adding because adding two different ID's with
8266 same IP replaces the old cache entry thus giving wrong route.
8267 The entry->router->connection is always the fastest route anyway
8268 so route cache may not be needed. Of course, new routes maybe
8269 established after receiving the ID when the entry->router->connection
8270 might not be anymore the most optimal.
8272 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Add route cache for received ID for fast routing.
8276 * Added silc_server_packet_route to route received packet on router
8277 that is not destined to us.
8279 * Renamed silc_server_get_route to silc_server_route_get.
8281 * Added id_string and id_string_len fields into SilcServer to
8282 include encoded ServerID for fast comparing without excess
8283 encoding of the ID's.
8285 * Cleaned up WHOIS command on server side. Added following static
8288 silc_server_command_whois_parse
8289 silc_server_command_whois_check
8290 silc_server_command_whois_send_reply
8291 silc_server_command_whois_from_client
8292 silc_server_command_whois_from_server
8294 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8295 arguments in command replies. All command functions should be
8296 updated to use this macro.
8298 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8300 * Minor typo fixes on command reply handling on server.
8302 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8304 * Added silc_server_command_add_to_channel internal routine to add
8305 the client to the channel after router has created the channel and
8306 sent command reply to the server.
8308 * Added generic silc_server_send_command to send any command from
8311 * Use static buffer with ID rendering instead of duplicating data.
8313 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8315 * Fixed a channel user mode bug when joining to a channel server gave
8316 everybody channel founder rights, oops.
8318 * We mark ourselves as the router of the incoming server connection
8319 if we are router ourselves. This way we can check in some packet
8320 sending functions whether it is locally connected server. For
8321 incoming router connections we put NULL.
8323 * For router sending packets locally means now always sending the
8324 packet cell wide; to local clients and local servers. For normal
8325 server sending packet locally means sending it to only local
8328 * Fixed the JOIN command to really work in router environment. If the
8329 channel is created it is always created by the router. Router is
8330 also responsible of making the initial joining to the channel,
8331 sending JOIN notify to the sending server and distributing
8332 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8333 does not exist server doesn't do anything else but forward the
8334 command to the router which performs everything.
8336 * Added silc_server_send_channel_key function to send the Channel Key
8339 * Added silc_server_create_channel_key to create new channel key. The
8340 channel key is now re-generated everytime someone joins or leaves
8341 a channel, as protocol dictates. Note: channel->key_len is the
8344 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8346 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8347 packet_receive.[ch] to separate packet sending and receiving
8348 routines. The server.[ch] now includes everything else including
8349 actual packet processing (writing and reading data) and other
8352 Renamed silc_server_private_message_send_internal to
8353 silc_server_send_private_message. The routine is still though
8354 used only to relay private messages as server does not send
8355 private messages itself.
8357 Renamed silc_server_new_channel to silc_server_create_new_channel
8358 and added new function sicl_server_new_channel that handles the
8359 incoming New Channel packet. Added also new sending function
8360 silc_server_send_new_channel to send New Channel Payload.
8362 * Added new function silc_server_notify to process incoming notify
8363 packet to the server/router. Server may then relay the notify
8364 to clients if needed.
8366 * Added new function silc_server_new_channel_user to process incoming
8367 New Channel User packet. Router will redistribute the packet and
8368 send JOIN notify to its local clients and locally connected servers
8369 if needed. Normal server will send JOIN notify to its local client
8370 on same channel when received this packet. Added also corresponding
8371 sending function silc_server_send_new_channel_user to sent the
8374 * Added boolean route argument to send_notif_to_channel and
8375 packet_send_to_channel functions to attempt to route the packet
8376 if it is TRUE and send only locally if it is FALSE.
8378 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8380 * silc_server_replace_id now broadcasts the received replace ID
8381 packet if it is not broadcast packet already. The router must
8382 broadcast to inform other routers about changed ID.
8384 * Added backpointer to server's router into SilcServer context in
8385 silcd/server_internal.h.
8387 * Fixed silc_server_packet_broadcast to send correct broadcast
8390 * The channel key is now distributed to the local client as soon
8391 as it is received from the router (in router environment) so that
8392 no other packet may be sent for the channel until client has
8395 * silc_server_remove_channel_user now broadcasts the received
8396 Remove Channel User packet if it is not broadcast packet already.
8397 The router must broadcast to inform other routers about removed
8400 * Added users field into SilcPacketContext that is a reference count
8401 of the context. One can increase the reference count by calling
8402 silc_packet_context_dup which is now changed to just increase the
8403 reference count instead of duplicating the data. The reference
8404 count is decresed by calling silc_packet_context_free that will
8405 free the data after the reference count hits zero.
8407 For now on the packet context and everything allocated into it
8408 (including the raw packet from network) must be freed by calling
8409 the new silc_packet_context_free function. Added also new function
8410 silc_packet_context_alloc that must be used now to allocate the
8411 context. This also means that if a routine is asynchronous from
8412 silc_[client/server]_packet_parse_type the packet context must
8413 be duplicated by calling silc_packet_context_dup. Otherwise it
8414 gets free'd after silc_[client/server]_packet_parse_type returns.
8415 Also, one must remember that if packet is duplicated then its
8416 reference count must be decresed by calling the free function as
8417 many times as it was duplicated.
8419 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8420 from both client and server.
8422 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8424 * Made joining to a channel working in router environment.
8426 * Cleaned up JOIN command on server side and create function
8427 silc_server_command_join_channel internal routine to make the
8430 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8432 * Changed silc_command_pending list to SilcDList. Also, added
8433 `ident' field to SilcServerCommandPending structure to identify
8434 the reply and to call correct callback.
8436 Added silc_server_command_pending_check function to replace the
8437 corresnponding macro. The silc_command_pending list is not
8440 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8441 to set identifier to previously allocated Command Payload. It
8442 is used to set identifier for command when resending Command
8445 * Added silc_command_payload_encode_payload to encode Command
8446 Payload buffer from SilcCommandPayload structure.
8448 * Added silc_argument_payload_encode_payload to encode Argument
8449 payload buffer from SilcArgumentPayload structure.
8451 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8453 * Changed WHOIS command to support router connection on server side.
8454 The whois request is always sent to router unless the server is
8455 standalone server. After server has received the reply from the
8456 router will it send the reply to the client.
8458 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8459 broadcast received broadcast packet. The function is used only
8460 by router. The broadcast packet is always sent to the router's
8463 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8464 render given ID to printable string, for log files for example.
8466 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8468 * Made basic router to router connections working. At least they
8469 can now connect to each other but nothing really works the way
8470 they are supposed - yet.
8472 * Added new initiator token to RouterConnection configuration
8473 file in silcd/serverconfig.[ch]. It is used to tell whether we
8474 are the initiator to the remote router or whether we'll expect
8475 the other end to connect.
8477 * Moved registering of listener task to silc_server_init, hence
8478 the server starts listenning as soon as it is run, even if it
8479 does not have connections to other routers. Let's see how well
8482 * Changed default connection retry timeouts for more suitable in
8485 * Removed cipher and such arguments from silc_idlist_add_client
8486 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8487 Added new function silc_idlist_add_data to add the keys and stuff
8490 * Added SilcIDListData structure and added it to SilcClientEntry
8491 and SilcServerEntry as their first field in the structure. This
8492 way we can explicitly cast the ID entries to the SilcIDListData
8493 structure and get common data for the entries. In past, we had
8494 to first check what type of connection it is and then cast it to
8495 correct ID entry type. Now, we can directly cast the opaque
8496 pointer to the SilcIDListData (no matter what ID entry it actually
8497 is) and get the data needed.
8499 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8501 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8502 in some circumstances even if threre were timeout tasks, though not
8503 IO tasks, but tasks anyway. Now fixed.
8505 * Defined SilcServerConnection structure to hold connection specific
8506 stuff about directly connected servers and routers. The definition
8507 is currently in silcd/server_internal.h. I thought about having
8508 a bit more important role fro this struct but for now it is used
8509 only when connecting to other server (or router actually).
8511 * Added connecting retry support in server when connecting to
8512 router(s). The retry feature implement exponential backoff
8513 algorithm. Also, added SilcServerParams structure to hold default
8514 parameters for server. For now, it include these retry settings
8515 and are hard coded. After server is moded to be as Silc Server
8516 Library this structure will be more important.
8518 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8520 * Changed client librarys channel->clients table to SilcList and
8521 changed code accordingly.
8523 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8525 * Changed client's channel table to SilcList and changed code
8526 accordingly. Also changed SilcChannelClientEntry to include back-
8527 pointer to the channel so that client entry can use that structure
8528 as list as well and we have fast cross-reference to the channel.
8529 This change dramatically decreased the complexity of channel
8530 handling with client entry and vice versa (removed one extra
8531 loop when searching for channel entry from many functions).
8533 * Changed server->sim from table to SilcDList and changed code
8536 * NAMES command can now be used from user interface. It will show
8537 the user list on the channel, neatly.
8539 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8540 Code now saves realname of the user if it becomes available.
8542 * Renamed configure.in to configure.in.pre and made ./prepare
8543 script to automatically add correct version string to
8544 configure.in which it creates from configure.in.pre.
8546 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8548 * NAMES command reply now shows users mode with the nickname when
8551 * Moved silc_client_ch[u]mode[_char] functions from
8552 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8553 place sucks, they are utility functions and should be in some
8556 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8558 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8561 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8565 * Added TRQ (efficient deque and list library) into lib/trq. This is
8566 a very good list library that is currently used in the SILC. Defined
8567 SilcList API over the library because I didn't like the API very
8568 much. See lib/trq/silclist.h for the API and examples of how to
8569 use the API. Fixed various places in the code to use the new
8570 SilcList API. The SilcList is meant for lists that has a structure
8571 already defined as a list. It is not suitable to add just some
8572 context to the list (in TRQ, the context is the list actually).
8574 So, I defined SilcDList that can be used for the purpose where
8575 predefined list structure does not exit. This can be used as
8576 such list. Now some context just can be added to the SilcDList.
8577 Currently this list is not used in the SILC just yet, though there
8578 are a lot places where this can replace dynamically allocated
8579 tables and I will fix these places, later, to use SilcDList.
8580 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8581 and use TRQ internally).
8583 Also fixed some annoying warning messages that the original TRQ
8584 code generated. Also minor changes to TRQ's Makefile.in.
8586 * Added support for querying by Client ID to both WHOIS and
8587 IDENTIFY commands into server, as required by the protocol.
8589 * Removed method function pointers from SilcBuffer structure. They
8590 weren't used to anything and just increased the context size for
8591 no good reason. This change also made silc_buffer_alloc and
8592 silc_buffer_free functions inline functions.
8594 * Disabled command flooding detection support until it's fixed so
8595 that it accepts commands in but does not execute them more than once
8598 * Added silc_net_localhost(), to return local hostname, into
8599 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8600 that must be initialized before calling silc_client_init.
8602 * Added new function: silc_server_send_notify_on_channels to send
8603 notify messages to all channels client has joined. It is assured
8604 that the message is sent only once per client.
8606 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8607 lib/silcutil/silcutil.[ch] as silc_format function. The new
8608 function is generic and is used by server as well, not only by
8609 the logging routines.
8611 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8612 the provided version string was not acceptable. Added new function:
8613 silc_ske_check_version into lib/silcske/silcske.h. The function
8614 must be implemented by the application (client or server) and it
8615 does not reside in the SKE library. The function checks the version
8616 string remote end sent.
8618 * Added back pointers (to opaque context and to SilcSocketConnection)
8619 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8621 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8622 duplicate packet context structure.
8624 * Changed `notify' client operation to send same arguments as client
8625 receives from server except for ID's. ID's are mapped to correct
8626 ID entry and that is returned. Also, if channel entry is not sent
8627 by server but the notify is for channel the channel entry is sent
8628 to application (otherwise application doesn't know that it is for
8629 channel (library gets it from packet's Destination ID)).
8631 * Added silc_client_remove_from_channels into client library to
8632 remove a client from all channels it has joined to. Used when
8633 received SIGNOFF notify from server. Added also new function
8634 silc_client_replace_from_channels to replace old ID entry with
8635 new ID entry on all channels. Used when received NICK_CHANGE
8638 * Fixed ID Cache list handling in silc_idlist_get_client in
8639 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8640 to get (or query) client by ID.
8642 * Updated TODO list.
8644 * Added connection authentication status message defined by the
8645 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8646 support for these into the code in client and server side.
8648 * Added generic function silc_client_send_command to send any command
8649 with variable argument list. Application should use this function
8650 to send commands if the command functions provided by the library
8651 does not suite for the application's user interface needs.
8653 * Added new `failure' client operation. Application is notified about
8654 received failure packet if client is executing a protocol. In this
8655 case the protocol's execution has failed.
8657 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8658 is required by the protocol.
8660 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8661 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8664 * Added status flag to SilcSKE object to indicate realtime status
8665 of the SKE protocol.
8667 * Application receives now exactly same command reply arguments as
8668 the library receives from server. However, if ID is received the
8669 corresponding ID entry is returned to the application (eg. Client
8670 ID is mapped to correct SilcClientEntry entry and that is returned).
8671 Changed command_reply client operation due to this change.
8673 * Changed all ID's in commands and in command replys as ID Payloads.
8674 Change affected both client and server side codes.
8676 All ID's sent in SILC network (with execption of ID's in SILC
8677 Packet header) are sent in ID Payload to support variable length
8680 * Server now notifies nick changes and notifies all clients on
8681 the channels about the new nickname (about the new Client ID,
8684 * Implemented CMODE command to change channel modes. Supports all
8685 channel modes defined by the protocol specs except ban and invite
8686 lists. (Also, private channel key mode is supported but support for
8687 setting private channel key in client is missing, thus, this mode
8688 has no effect on client side (except that server requires that the
8689 client uses private channel key and normal channel traffic does not
8692 Also, invite mode works per se, but INVITE command does not work
8693 yet correctly, so you can set channel as invite only channel but
8694 inviting clients to the channel does not work (it is yet to be
8695 thought what's the best way to do it).
8697 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8698 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8699 Implemented CUMODE command to change user's mode on the channel.
8700 Supports all modes defined by the protocol specs.
8702 * Added NAMES command reply to return users modes on the channel.
8704 * Removed unnecessary and slow ciphers from lib/silccrypt.
8706 * Set SO_KEEPALIVE option to connection sockets by default.
8708 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8710 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8711 redefined the Notify Payload into protocol specs.
8713 * Added silc_id_payload_parse_id to get ID directly from raw
8716 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8718 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8719 accept searching by Client ID as well.
8721 * Added support for LEAVE and SIGNOFF notify types in client library.
8723 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8724 to parse ID Payload from raw data.
8726 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8728 * Added flags parameter into silc_ske_assemble_security_properties
8729 function in lib/silcske/silcske.[ch].
8731 * Changed notify client operation to fit better for notify messages
8732 sent by server. The notify payload received from server is now
8733 passed to the application (after parsing it to SilcNotifyPayload).
8734 It is application's responsibility to retrieve the arguments
8735 from the payload and show the message the way it wants. The message
8736 sent by server is implementation specific.
8738 * Changed public keys to comply with the protocol specification.
8739 Old public keys are not supported anymore and are not compatible.
8741 * Removed nickname from Channel Payload as the latest draft removed
8742 it. The client must resolve the nickname from the NAMES command
8743 reply received when it joined the channel.
8745 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8747 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8749 * Fixed some errors in protocol specification drafts.
8751 * Created lib/silccore/silcnotify.c to implement Notify Payload
8752 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8753 generic payloads described by protocol specifications. The file
8754 includes implementations for ID Payload and Argument Payload.
8756 * Changed Command Payload implementation to use the new Argument
8757 Payload. Changed command_xxxx_payload to command_payload_xxxx
8758 to comply with SILC coding conventions.
8760 * Added suppport for Argument Payload handling in Notify Payload
8761 implementation as protocol requires it. Added the new support
8762 into server and client lib as well.
8764 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8766 * Added support for multiple nicknames on same channel. [n] is
8767 added locally to the nickname if there are more than one same
8768 nicknames on the channel.
8770 * Server now sends all nicknames that matched WHOIS request.
8771 Client also shows the list received from server.
8773 * Added TOPIC command to client side. User can now set and show
8774 current topic on channel.
8776 * Added MOTD command to client and server. Also, server sends the
8777 motd when client connects to the server.
8779 * Changed version strings to comply ISO 8601.
8781 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8783 * Fixed protocol error handling in client library. It should now
8784 cope even if the SKE fails for some reason.
8786 * Made new protocol specification drafts for submitting to IETF.
8788 * Implemented TOPIC command to server in silcd/command.c.
8790 * Added two new notify types into lib/silccore/silcnotify.h:
8791 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8792 notify nickname change and topic setting/change on a channel.
8794 * API change of command_reply operation in client library. The
8795 application gets now the status type received from server as well.
8797 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8799 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8801 * Cras fixed and optimized the packet handling even further and
8802 it should work now. Minor change to the prototype of function
8803 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8805 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8807 * Added new function into lib/silcutil/silcschedule.[ch]:
8808 silc_schedule_with_fd to select() a specified fd. The function
8809 returns after timeout expires or data arrives or goes. The
8810 function is used by packet routines to wait that all data is
8811 received from network.
8813 * Fixed data reading from network in lib/silccore/silcpacket.c.
8814 The code now assures that all data is read from the fd and then
8815 continues packet processing. This was a bug fix since the code
8816 used to drop some data in some circumstances.
8818 * Added new function into lib/silcclient/client.[ch]:
8819 silc_client_start_key_exchange to start key exchange after
8820 connection has been established to server. The code internally
8821 now uses this funtion but its main purpose was to provide it
8822 for applications that perform their own connecting. After
8823 application has created a connection it merely calls this
8824 function to start the key exchange between client and server.
8825 The library takes care of everything else after that.
8827 Updated also lib/silcclient/README to explain the usage of
8830 * Do not send to application information that connection has
8831 been established. Application gets notified it by connect
8834 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8836 * Applied cras's patch to add silc_schedule_one function. The
8837 function runs scheduler once and returns.
8839 * Fixed the scheduler after cras messed it up. The timeout
8840 handling works now as it's supposed to work.
8842 * Added into lib/silccore/ silcnotify.h to include notify
8843 message types support. Changed silc_server_send_notify*
8844 functions, in server.[ch], to support those new notify types.
8845 Added the support for the notify types into client library,
8846 as well. Added new notify client operation into ops.h in
8849 * Changed silc_server_packet_send_to_channel to send normal
8850 packets instead of just channel message packets. The function
8851 is now used to send the notify packets to channels. It is not
8852 used to send channel message packets anymore, as server never
8855 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8856 va_arg()s as it seems to require it nowadays. I guess, if SILC
8857 is compiled with older va_arg() the new code should work anyway.
8859 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8861 * Splitted core library. Core library (lib/silccore) includes
8862 now only SILC protocol specific core (and common) components.
8863 Created new utility library (lib/silcutil) that includes more
8864 generic purpose stuff. The stuff for util library was taken
8865 from the old core library. This was minor and easy split.
8867 * Created SILC Client Library (lib/silcclient) that includes
8868 implementation of the SILC client without user interface. This
8869 was major move from silc/ directory. The code has been changed
8870 so that it is transparent towards the user interface. The
8871 silc/ directory includes now the same user interface as before
8872 and it uses the new client library. Read lib/silcclient/README.
8873 Basicly, the client library performs everything else related
8874 to SILC except user interface handling. Also, configuration
8875 files are considered to be part of user interface and library
8876 does not handle them.
8878 This change also changed a lot of structures, function naming etc.
8879 Most important change was that SilcClientWindow object was
8880 renamed to SilcClientConnection in the client library. Created
8881 also new file lib/silcclient/ops.h. Also added new files
8882 silc/local_command.[ch] and silc/client_ops.[ch].
8884 All these changes were made to make it easier for user interface
8885 designers to create what ever user interface for the SILC client
8888 It is also expected that the server will be moved to lib
8889 directory as well and SILC Server Library will be created;
8890 sometimes in the future.
8892 * Removed Local commands from lib/silccore/silccommand.h as
8893 they are application specific and new client library does not
8894 handle any of those anymore.
8896 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8897 old client implementation in silc/.
8899 * Added support for callback functions in SILC_LOG_* macros.
8900 Application can now set its own callbacks that will be called
8901 instead of using the default functions that will always print
8902 the debug messages to stderr (or stdout). Also, debugging can
8903 now be disabled by setting silc_debug to FALSE and re-enabled by
8904 setting it to TRUE. Note, that logging will still work even
8905 if debugging is disabled.
8907 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8908 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8909 silc_log_reset_debug_callbacks.
8911 * To enable debugging in silc client one must give now -d
8912 option on command line.
8914 * Changed silc_schedule_init to automatically allocate task queues
8915 if they are not allocated before calling it.
8917 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8919 * Added GMP 3.1 into math library.
8921 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8923 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8924 a channel in SILC network. The packet is used by servers and
8925 routers to notify other routers that user has left a channel.
8926 This little feature was missing until now. Added the feature
8927 to protocol specification as well.
8929 Added functions: silc_server_send_remove_channel_user and
8930 silc_server_remove_channel_user into server.[ch].
8932 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8933 lib/silccore/silcpacket.h. However, they are not implemented
8936 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8938 * Fixed joining to a channel and sending channel messages
8939 between server and router. The channel message sending should
8940 now work inside a cell.
8942 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8944 * Fixed the private message sending between server and router.
8945 The private message sending should now work inside a cell.
8947 * Added silc_server_replace_id into server.[ch] to replace
8948 existing ID in the SILC network.
8950 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8951 and silc_idlist_replace_server_id into idlist.[ch] in server.
8953 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8955 * Fixed the server to server connections. Server can again now
8956 connect to router. Router to router connections probably does
8959 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8961 * Added dynamic protocol registering support. Now protocols can
8962 registered and unregistered on the fly. Patch by cras.
8964 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8966 * Added lib/contrib directory to hold routines that some platforms
8967 don't have but are needed by SILC.
8969 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8970 into lin/contrib to provide getopt() and getopt_long() for
8971 those who don't have it.
8973 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8975 * Added AWAY command to client. When away message is set and
8976 client receives a private message packet the client automatically
8977 replies to the sender with the away message.
8979 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8980 bug seemed to be the cause of recent problems when compiling
8983 * Added version detection support to SKE protocol specification
8984 and added the new changes to the SKE implementation as well.
8985 There were other minor changes in the SKE protocol as well.
8987 Many changes in lib/silcske/silcske.[ch] and in
8988 lib/silcske/payload.[ch].
8990 * Added ^U functionality, clear input line. Patch from cras.
8992 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8994 * Mainly small bugfixes on core library. Fixed some debugging
8995 logging and buffer overflow in silclog.c.
8997 * Updated config.sub and config.guess on the distribution tree.
8999 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9001 * Added command lagging support in server. Client may execute
9002 commands now only once in two seconds.
9004 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9006 * Optimized packet reception. MAC computation and checking is now
9007 also more optimized. A lot previously duplicated code is now
9008 used as generic by both client and server.
9010 * Fixed key pair generation in clientutil.c
9012 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9014 * Added into lib/silccore/silcbufutil.[ch] new function;
9015 silc_buffer_realloc.
9017 * Moved generic packet sending/encryption functions to
9018 lib/silccore/silcpacket.[ch] from client and server. Some
9019 rewriting of the functions.
9021 * Moved all generic packet reception/decryption functions to
9022 lib/silccore/silcpacket.[ch] from client and server. The
9023 packet processing is now much cleaner in both client and server.
9024 These were major changes in both client and server.
9026 * Created many common functions in server to do packet sending.
9027 Previously code were duplicated a lot, this has been removed
9030 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9032 * Rewrote major parts of the ID cache system. Don't know
9033 whether it is better now or not but at least the API is more
9036 * Major rewrite on ID cache stuff on client because of the ID
9037 cache API changes. Added idlist.c to client.
9039 * Also major rewrite on ID cache stuff on server as well.
9040 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9041 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9042 in hand, instead they are all put into the ID cache system now.
9043 All server_idlist_* routines uses ID cache now instead of
9044 traversing its own lists (those lists does not exist anymore).
9045 SilcIDList though still exists. Also, SilcXXXEntry's are
9048 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9050 * Finally made the SKE implementation compliant to the protocol
9051 specification. All mp integers are now binary encoded as
9052 opposed being HEX encoded.
9054 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9057 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9058 functions: silc_[encode/decode]_pem. Also added function
9059 silc_encode_pem_file to PEM encode with newlines ('\n') for
9062 * SILC public keys are now encoded either PEM or binary. Same
9063 option is for private keys as well. By default private keys
9064 are binary encoded and public keys PEM encoded. Silly HEX
9065 encoding were removed.
9067 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9068 function to create fingerprints.
9070 * Fixed a bug in SHA1; does not change the original data anymore.
9072 * Partly implemented INFO command on client and server side.
9073 Fixed CLEAR command. Changes to SERVER command; show current
9074 server(s) when giving command without arguments. Added
9075 VERSION command to client.
9077 * Added check to server that unregistered connections cannot
9078 execute commands (unless it is specificly allowed).
9080 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9082 * Fixed screen refresh.
9084 * Fixed channel joining bug from client. On some circumstances
9085 client tried to join to a channel it had already joined.
9087 * Added public key verification process into client's protocol.c.
9088 The client now verifies the public key from user and saves
9089 it into ~./silc/serverkeys/ directory.
9091 Added into: clientutil.[ch]: silc_client_verify_server_key.
9093 * Changed SKE protocol's silc_ske_initiator_finish function
9094 to accept callback function that verifies the received public
9095 key. Removed old silc_ske_verify_public_key function.
9097 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9099 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9100 silc_pkcs_private_key[_data]_set.
9102 * Made the password and public authentication more cleaner in
9103 server's protocol.c.
9105 * Removed historic and obsolete protocol `channel_auth' from
9106 both client and server.
9108 * Removed wrong way of sending command status messages from
9109 server to client in server's command.c. The old way violated
9110 protocol specification.
9112 Changes to silccore/silccommand.[ch]: removed
9113 silc_command_encode_status_payload -> not needed anymore,
9114 changed silc_command_encode_payload_va to accept extra
9115 argument on variable argument list. The argument type must
9116 now be provided to the function. Also, added new function:
9117 silc_command_encode_reply_payload_va which is same as
9118 normal command_encode_payload_va except command status type
9119 is provided as extra argument.
9121 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9123 * Added ~./silc directory handling. The directory includes the
9124 public and private keys for the client.
9126 Added silc_client_check_silc_dir, silc_client_create_identifier
9127 and silc_client_load_keys.
9129 * Implemented SILC protocol compliant public key. Added public
9130 and private key saving to and loading from files.
9132 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9133 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9134 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9135 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9136 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9138 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9139 silc_pkcs_load_[public/private]_key.
9141 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9143 * Added silc_server_get_route (route.[ch]) to get connection
9144 data for the fastest route for given ID.
9146 * Implemented INVITE command on client and server. The command
9147 were re-defined in the SILC Protocol Specification and the
9148 implementation now complies with the specification.
9150 * Implemented PING command on client and server.
9152 * Implemented NAMES command on client and server. The server side
9153 supports currently only normal server not router server yet.
9154 Some changes to NAMES definition in SILC protocol specification.
9156 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9158 * Implemented LEAVE command on client and server.
9160 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9161 again. This change was made to the protocol as well. Server
9162 should not violate the protocol specification anymore.
9164 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9166 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9167 was tested. SOCKS4 was not but should work anyway.
