76 Fri Oct 11 23:52:17 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
78 * Some strncat -> silc_strncat changes our the core and
81 * Added SILC_SKE_STATUS_SIGNATURE_ERROR and OUT_OF_MEMORY
82 errors. Added better error printing to SKE library.
83 Affected files lib/silcske/silcske.c, silcske_status.h and
86 * Save the PKCS key length even if only private key is set to
87 SilcPKCS. Affected file lib/silccrypt/silcpkcs.[ch] and rsa.c.
89 * Fixed the usage of silc_pkcs_get_key_len since it returns the
90 length in bits not in bytes. Affected files are
91 lib/silcske/silcske.c, lib/silccore/silcauth.c and
94 Wed Oct 9 17:22:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
96 * Added silc_attribute_payload_encode_data to directly encode
97 the data into the attributes buffer. Renamed function
98 silc_attribute_payload_parse_list to silc_attribute_payload_parse.
99 Affected files are lib/silccore/silcattrs.[ch].

106 the Requested Attributes from the client. Fixed memory leak
107 in client entry freeing. Affected files silcd/server_query.c
110 * Added Requested Attributes support into SILC Client Library.
111 It is not able to send requested attributes in WHOIS command,
112 and also receive and process requested attributes. Added
113 silc_client_attribute_[add|del] and silc_client_attributes_get
114 functions. Added also `ignore_requested_attributes' to the
115 SilcClientParams to not use attributes in client. Affected
116 files are lib/silcclient/command.c, client_attrs.[ch],
117 silcclient.h, client_internal and client.[ch].
119 * Changed the silc_client_get_client_by_id to support Requested
120 Attributes, it takes them as argument now. Affected file
121 is lib/silcclient/silcclient.h, and idlist.c.
123 * Added -details option to WHOIS command in Irssi SILC Client
124 to support the requested attributes. By default it requests
125 all attributes. Affected file lib/silcclient/command.c and
126 irssi/doc/help/in/whois.in.
128 Tue Oct 8 17:58:28 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Add also SERVICE attribute for server-constructed attribute
131 data. Also digitally sign the attributes and add

133 silcd/server_query.c.
135 Mon Oct 7 18:25:35 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
137 * Changed the silc_attribute_payload_encode to support list
138 of attributes (function may be called several times to add
139 a new attribute). Removed the silc_attribute_payload_encode_list
140 function. The encoding function now also automatically encodes
141 the data, so the caller does not need to do that. Affected
142 files lib/silccore/silcattrs.[ch].
144 * Added support for replying on behalf of the user to the
145 Requested Attributes in WHOIS command in the server. Affected
146 file silcd/server_query.c.
148 * SILC_NOT_IMPLEMENTED macro use SILC_LOG_INFO now instead of
149 SILC_LOG_DEBUG. Affected file lib/silcutil/silclog.h.
151 Sun Oct 6 16:48:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
153 * Don't swtich to become primary router if we are backup if
154 decryption error has occurred. Affected file silcd/server.c.
156 * Fixed a bug in backup router IP address comparison in
157 silc_server_backup_get.
159 Save now also the port of the server/router and use that
160 in comparison as well. Affected file silcd/server_backup.c.
162 * Normal server now reconnects to backup router automatically
163 if connection is lost to it. Affected file silcd/server.c.
165 Thu Sep 26 13:51:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
167 * If packet processing fails (like integrity check fails)
168 the connection is closed now. Affected files are
169 lib/silccore/silcpacket.c and silcd/server.c.
171 Mon Sep 23 10:59:39 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

179 * Rewrote WHOIS, WHOWAS and IDENTIFY commands in the server.
180 Added server_query.[ch] which provides one interface for
181 querying information using all three commands.
183 * Changed all "typedef unsigned char" in core library to
186 Sat Sep 21 21:36:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

195 * Resumed client packet handling from server put the resumed
196 client on wrong list on router and caused the client not
197 be present on the network anymore. Now fixed to put the
198 client to correct list. Affected file silcd/packet_receive.c.
200 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
202 * Various cleanup in error message output in config parsing code
203 and in server init code. Fixed error log files containing
204 too many newlines ('\n') in some situations. Affected files are
205 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
207 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
209 * Use the reverse lookupped hostname in client internals
210 instead of one user provided us as remote server name.
211 Affected file lib/silcclient/client.c.
213 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
215 * Added 'app_context' to silc_schedule_init. It is an
216 application specific context that is delivered to application
217 in task callback functions. Affected files are
218 lib/silcutil/silcutil.[ch].
220 * The hb_context in SilcSocketConnection is not freed
221 automatically anymore (application must free it). Freeing
222 it automatic is inconsistent. Affected files are
223 lib/silcutil/silcsockconn.[ch].
225 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
227 * Added support for removing explicitly added client connections
228 in rehash and closing the client connections if they were
229 unconfigured in the rehash. Affected file silcd/server.c.
231 * Added support for aborting automatically pending commands
232 that never receives the reply (to avoid memory leaks).
233 Added also silc_server_command_pending_timed to set the
234 specific timeout for pending command. Affected files are
235 silcd/command[_reply].[ch].
237 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
238 specs and lib/silccore/silcstatus.h.
240 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
242 * Changed the silc_get_time to accept time value as argument
243 or if zero is sent return current local time. Affected
244 file lib/silcutil/silcutil.[ch].
246 * Added STATS command to client library and Irssi SILC client.
247 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
249 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Assure that channel key is set before sending it. May
252 crash server otherwise. Affected file silcd/packet_send.c.
254 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
256 * Assure that endless loop cannot happen with detached client
257 resolving on normal server. Added idlist status
258 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
259 silcd/idlist.h and silcd/packet_receive.c.
261 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Incoming file transfer request cannot use same session as
264 the sending session. This can happen when sending file to
265 yourself. Crashed the client on quit. Affected file
266 lib/silcclient/client_ftp.c. Bug #24.
268 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
270 * Implemented the draft-riikonen-precense-attrs draft and
271 the Attribute Payload into the lib/silccore/silcattrs.[ch].
273 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
275 * Distribute the SERVER_SIGNOFF notify also to local backup
276 routers from the primary router. The backup router may not
277 have the signing of local server directly connected and need
278 to know about the signoff. Affected file silcd/server_util.c.
280 * Use the primary router as the origin of the locally connected
281 server when it is disconnecting from the backup router since
282 that's where it really is coming from. Now the clients from
283 the disconnecting server are removed correctly and "shadow"
284 clients are not left to the backup router. Affected file
287 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
289 * If normal server is standalone and found existing but disabled
290 channel, do not re-create the channel since it creates
291 duplicate same channels. Affected file silcd/server.c.
293 * Added anonymous client connections support to server. New
294 "anonymous" configuration option to ConnectionParams section
295 added. If set to true, the username and hostname information
296 of the client will be scrambled and anonymous user mode is
297 set automatically to the user. Affected files are
298 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
300 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
302 * In JOIN notify handling, mark that the cache entry of the
303 client cannot be expired. Can cause crashes on normal
304 server (asserts client->channels). Affected file is
305 silcd/packet_receive.c.
307 * From now on distribution versions are used as protocol versions
308 instead of by default using the Toolkit base version as protocol
309 version. Affected file prepare.
311 * Do not set the locally resolved hostname for local client
312 entry but take what server sends. This way the real hostname
313 is showed in WHOIS for yourself. Affected file is
314 lib/silcclient/idlist.c and lib/silcclient/client.c.
316 * Resolve local info with IDENTIFY when connecting to server.y
318 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
320 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
321 for implied search (not needed on platforms which has native
322 pthreads library). Use --without-pthreads to disable threads.
323 Affected file is configure.in.pre
325 * Fixed --with-iconv on platforms which need to bypass (broken)
326 native iconv(). Affected file is configure.in.pre
328 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Moved -C option parsing in Irssi SILC client at same time
331 as other options. The UI was initialized earlier and caused
332 problems on command line. Bug #16. Affected file is
333 irssi/src/silc/core/silc-core.c.
335 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
337 * Added global variable silc_log_timestamp that tells silclog
338 wether to print or not the timestamp in the logging files.
339 Affected file lib/silcutil/silclog.[ch].
341 * Added silcd configuration option Timestamp in the Logging
342 section. Affected file silcd/serverconfig.[ch],
343 doc/example_silcd.conf.in.
345 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
347 * Fixed fingerprint checking to check for entirely empty
348 fingerprint instead of two first bytes when determining
349 if it is set. Bug #18. Affected file silcd/command.c.
351 * Fixed duplicate PKCS name registering to not allow it.
352 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
354 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
356 * Conditionalize non-gcc compiler optimizations for various
357 platforms, enable those commented out. Cleanups.
358 Affected file lib/silcmath/mpi/configure.in
360 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
362 * silc_rng_exec_command() left zombie processes if command
363 didn't generate any output. Affected file
364 lib/silccrypt/silcrng.c
366 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
368 * Rewrote iconv checking, introduce --with-iconv for systems
369 which rely on libiconv. Check if iconv() provided by libc
370 is good enough, otherwise demand libiconv. Affected file
373 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
375 * Search for ldopen() also in libc. This enables SIM support
376 on *BSD systems. Based on patch from Alex Zepeda. Affected
377 file configure.in.pre
379 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
381 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
382 This fixes prepare on *BSD systems. Affected file
385 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
387 * More fixed for not having purge timeout for global clients
388 that are on channel. Affected files silcd/command_reply.c
391 * Fixed the rekey protocol to work with backup router connections.
392 Rekey packets are now allowed on disabled connections as
393 well. Affected files silcd/packet_send.c and server.c.
395 * Do not switch to be as backup router when shutting down and
396 closing the primary connection. Affected file silcd/server.c.
398 * Fixed memory leaks in backup router deleting. Added
399 silc_server_backup_free to free all data during shutdown of
400 server. Affected files silcd/server_backup.[ch].
402 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
404 * Do not process commands if the sock->user_data is NULL.
405 Affected file silcd/command.c.
407 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Fixed buffer overflow and security problems (loosing bits
410 in CFB encryption) in SILC RNG. Problems reported by
411 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
413 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Added yet more checks that client is not expired on global
416 list if it is on channels. Affected file is
417 silcd/command_reply.c.
419 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Merged c0ffee's MIME signal patch which adds support for
422 sending also MIME messages in Irssi SILC Client, and handling
423 received MIME messages in a signal (and perhaps doing something
424 to non-textual MIME messages).
426 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
428 * Fixed pending command deletion in server and client library
429 to check the whole list instead of breaking after first found.
430 The affected files are silcd/command.[ch] and
431 lib/silcclient/command.[ch].
433 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
435 * Return NO_SUCH_CHANNEL error in USERS for channel that is
436 secret or private, otherwise it's possible to find out
437 whether a secret channel exists or not. Affected file
440 * If CMODE change fails during the mode setting, assure that
441 the old mode mask is set for the channel back. Affected
442 file silcd/command.c.
444 * Fixed passphrase saving on +a channel on normal server
445 after successful JOIN command. Affected file silcd/command.c.
447 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
449 * Remove server/router operator privileges in DETACH command,
450 since it's possible to resume to server where these
451 privileges would not be allowed for the client. Affected
452 file silcd/command.c.
454 * Do not set to wait for backup in rehash of the server.
455 Affected file silcd/server.c.
457 * Do not check listener sockets when counting how many
458 socket connections we have. Affected file is
461 * Do not announce disconnected clients that are remaining
462 in history (for WHOWAS). This is because SIGNOFF notify
463 for these has been sent earlier already. Affected file
466 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Buffer overflow with CUMODE command's mode->mode character
469 conversion. Reported by Ville Räsänen. Affected file
470 lib/silcutil/silcutil.c.
472 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
474 * Allow heartbeat packets to go disabled connections anyway.
475 Affected files silcd/server.c and silcd/packet_send.c.
477 * Do not broadcast New Channel packets with List flag set
478 in the packet to backup routers. The router must check
479 for the correctness of the packets before sending them.
480 It is possible that router will have enforce Channel ID
481 change and this would cause desync in the backup router.
482 Affected file silcd/packet_receive.c.
484 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
485 are handled in list parsing. They are not list packets
486 anymore. Affected file silcd/packet_receive.c.
488 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
490 * Stop waiting for backup router through the timeout, not
491 directly after backup router has arrived. Affected file
494 * Do not re-create channel keys and send them when removing
495 clients in server shutdown. Affected files are
496 silcd/server_internal.h and silcd/server_util.c.
498 * Notify distribution to backup routers was missing from
499 the silc_server_send_notify_dest function which caused
500 desyncing problems with backup router. Affected file is
503 * The client's channel removing was working wrong on
504 backup router. It assumed that it doesn't know global
505 information but backup router does know. For this reason
506 it could remove channel when it wasn't supposed to do that.
507 Affected file silcd/server.c and silcd/server_util.c.
509 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
511 * Stop for a couple seconds after badkup router has become
512 primary router. Affected file silcd/server.c.
514 * Added silc_server_remove_servers_by_server, which is used
515 to remove servers originated from some other server. Also
516 clients of those servers can be removed too. Affected file
517 silcd/server_util.[ch].
519 * When removing clients after a server has signed of remove
520 also all servers behind that server (unless they are known
521 to be available locally), and send SERVER_SIGNOFF for each
522 of the server separately. Also the signed off clients are
523 sent now separately per signed off server. The affected files
524 are silcd/server.c and silcd/server_util.[ch].
526 * All servers added with silc_idlist_add_server must always
527 have both "router" and "connection" pointers set. Otherwise,
528 bad server entries may be left around in the cache.
529 Affected file silcd/command_reply.c.
531 * Do not create the channel key in NEW_CHANNEL packet
532 processing if the channel is empty. Affected file
533 silcd/packet_receive.c.
535 * Completed backup router support for standalone routers.
536 Supports also servers in the cell that do not use the backup
539 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Fixed a bug in silc_string_regexify which did not add '^'
542 at the start of each string, and thus the matching was
543 not explicit. For example ban list iikone@*!*@* would
544 match also "priikone", which is wrong, it would have to be
545 *iikone@*!*@* to match also "priikone". Affected
546 file lib/silcutil/unix/silcunixutil.c.
548 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
550 * Enable all local server connections before updating client
551 caches when we've become backup router. Otherwise, signoff
552 packets may not reach the clients. Affected files are
553 silcd/server.c and silcd/server_util.[ch].
555 * Fixed a bug in version string parsing which could crash
556 the program with specially formatted version string.
557 Bug reported and patch provided by Ville Räsänen. Affected
558 file lib/silcutil/silcutil.c.
560 * Handle the disconnection immediately when DISCONNECT
561 packet is received in server. Affected file silcd/server.c.
563 * Primary router now waits a short time (10 seconds) for
564 backup router connection before accepting any other
565 connection (except local). Affected file silcd/server.c,
568 * Fixed a crash in client libary in NICK_CHANGE notify when
569 NICK_CHANGE arrived for client entry we are resolving
570 currently. Affected file lib/silcclient/client_notify.c.
572 * Call the sconn->callback completion even if error had
573 occurred. Start reconnecting always if connection to
574 primary router fails during backup router protocol.
575 Affected files silcd/server.c and server_backup.c.
577 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
579 * Added functions silc_server_send_opers and
580 silc_server_send_opers_notify to send packets stricly
581 to operators. Added macro SILC_SERVER_SEND_OPERS macro
582 to send variable argument notify to operators.
583 Affected files silcd/packet_send.[ch] and silcd/server.h.
585 * Removed UMODE rights checking with UMODE_CHANGE notify.
586 Affected file silcd/packet_receive.c.
588 * Server/router operator now receives notify when network
589 switches to backup router and when it resumes the use of
590 primary router. Affected file silcd/server.c and
591 silcd/server_backup.c.
593 * Fixed the updating of client information after backup
594 resuming protocol is over; update all except local clients
595 to the new primary router. The affected file is
598 * Added support for closing active connections in rehash
599 that were unconfigured by the user. Supports currently
600 closing server and router connections. Affected file
603 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
605 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
607 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
608 is NULL since seems that on some platforms NULL is allowed
609 and on some it's not. Fallback encoding is used instead.
610 Affected file lib/silcutil/silcstrutil.c.
612 * Fixed statistics updating for incoming server connection
613 which could cause problems when re-connecting. Affected
616 * Preliminary backup router support for standalone router
617 added. Affected files in silcd/.
619 * Mark server connections in backup router disabled before
620 and after backup protocol. Affected file is
621 silcd/server_backup.c.
623 * Added support for reconnecting to remote server connection
624 even if the protocol fails, and if the configuration wants
625 us to keep trying to connect anyway.
627 Server connection is not allowed to backup router if
628 backup router does not have connection to primary router yet.
630 Affected file is silcd/server.c.

639 notify only after it's resolved so that all notifys are
640 handled in same order as received from the server.
642 Added similar resolver check to channel entries. Every
643 notify that cause resolving of any information that affects
644 channel entry marks the channel entry in waiting state.
645 After whatever resolving is over the waiters are signalled
646 and only then the notifys are handled in the same order
647 as delivered from the server.
649 Affected files are lib/silcclient/idlist.[ch], and
652 * Fixed KILLED notify handling in normal server. Affected
653 file silcd/packet_receive.c.
655 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
656 is locally connected, or was locally connected (but may
657 be detached and connection is not active). Added also
658 SILC_IS_LOCAL for checking this status. Affected files
659 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,

662 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
664 * Don't send or handle TOPIC_SET if topic is already set and
665 is same as being set. Affected files silcd/command.c and
666 silcd/packet_receive.c.
668 * Fixed CMODE change rights checking to work correctly when
669 removing modes by operator. Affected file is
672 * Fixed some handling with New Channel packet in router and
673 fixed some CMODE_CHANGE notify handling in server and router.
674 Affected file is silcd/packet_receive.c.

686 to the sender of the notify too, to avoid situation where two
687 notifys are in the network at the same time going to oppsite
688 directions. Affected file silcd/packet_receice.c.
690 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
692 * Delete the client from channel even if the cilent->id is
693 NULL. It was possible that client was deleted without
694 removing from channels (theoretically at least). Affected
695 file silcd/server.c and silcd/server_util.c.
697 * Free the client data too when resuming is not successful.
698 Affected file silcd/packet_receive.c.
700 * Merged some code from c0ffee's silc-plugin. Affected files
701 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
703 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
704 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
705 to the primary router connection, the other one returns
706 TRUE if packet must be broadcasted to network.
708 * All notifys that are destined to primary router (to network)
709 are now automatically sent to backup routers even if the
710 router is standalone (and has backup router). Affected files
713 * Added --without-irssi and --without-silcd configuration
714 options for disabling the compilation of these applications.
715 Affected file configure.in.pre and prepare.

741 command reply from router, on normal server. Otherwise
742 joinig +a channels from normal server is not possible.
743 Affected file silcd/command.c.
745 * Fixed a bug in TOPIC_SET notify handling. The notifier
746 may be other than client too, like server or channel.
747 It expected it to always be only client and ignored the
748 notify. Affected file silcd/packet_recieve.c.
750 * Removed some (unnecessary) debug printing from
751 lib/silccore/silcid.c and lib/silccore/silcargument.c.
753 * Do not force CMODE_CHANGE when server is announcing new
756 Router announces stuff only after server reannounces channel
757 after CHANNEL_CHANGE notify.
759 These fixes optimizes the announcing procedure, and perhaps
760 fixes some problems too. Affected file silcd/packet_receive.c.
762 * Fixed SERVER_SIGNOFF sending to local clients. It was
763 totally broken and sent the notify to all local clients,
764 instead of only to those that was on same channel as the
765 signing off clients. Affected file silcd/server_util.c.
767 * Added -D option to server. It can be used to give debug
768 level. The levels are from 0 - 99, and are predefined for
769 smooth server debugging. (see silcd.c for the predefined
770 levels). Affected file silcd/server.c.
772 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

780 * When authenticating as founder during JOIN command, check
781 that the one authenticating becomes the only founder on the
782 channel. Affected file silcd/command.c.
784 * Better checking for founder mode setting when CUMODE_CHANGE
785 notify is received. Affected file silcd/packet_receive.c.
787 * Close all connections when shutting down the server by sending
788 DISCONNECT packet. Close all listeners too when shutting

823 core library, and implemented it. All textual messages SHOULD
824 use this flag and the message MUST be UTF-8 encoded.
825 All text messages sent by Irssi SILC client are now UTF-8
826 encoded (regardless whether the terminal supports UTF-8 or not).
827 Affected files are lib/silccore/silcchannel.h,
828 irssi/src/silc/core/silc-servers.c, silc-channels.c and

1376 * Redefined the Status Payload to include now two 8 bit fields,
1377 instead of one 16 bit field. This now makes it possible to
1378 send list of errors. Updated the protocol specs and the code
1379 in core library, client library and server. Protocol TODO #1.
1380 Affected files are lib/silccore/silccommand.[ch],
1381 lib/silcclient/command_reply.[ch], silcd/command.c,

1411 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1413 * Added STATS command to the protocol after all, to return
1414 various statistical information about the network. It can
1415 be used by clients to retrieve statistical information, and
1416 servers may use it to to fetch cell and network wide
1417 statistics from router. Updated the protocol specs and
1418 implemented it to the server. Protocol TODO #16.
1419 Affected files are lib/silccore/silccommand, silcd/command.[ch],

1424 * The LIST command reply in client libary now adds new channel
1425 entry if the returned channel doesn't exist yet in cache,
1426 and returns the channel entry to the application in the
1427 command_reply client operation. Affected file is
1428 lib/silcclient/command_reply.c.
1430 * Changed the channel message payload's MAC generation to
1431 include the IV in the MAC as well. This way all relevant
1432 parts of the channel message payload are authenticated also
1433 with the channel message MAC (and not only by packet MAC).
1434 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1435 Affected file is lib/silccore/silcchannel.c.
1437 * Fixed the SKE to save the remote version, since the

1512 to define the payload for DATA flag. Added the flags to
1513 the implementation. Protocol TODO #9. Affected file is
1514 lib/silccore/silcchannel.h.
1516 Changed the client library to return the message length

1560 * Some client implementations quit network by doing first LEAVE
1561 and then immediately SIGNOFF (like Bombyx). We now do check
1562 after a short time after LEAVE notify and check whether the
1563 client is still valid after LEAVE, and if not we remove it from
1564 cache. Affected file is lib/silcclient/client_notify.c.
1566 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1582 Affected files are lib/silccore/silcpacket.[ch].
1584 * Made strict checks for valid SILC IDs. Affected file is
1585 lib/silccore/silcid.c.
1587 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1589 * Changed the object argument for silc_cipher_register,
1590 silc_hash_register, silc_hmac_register and silc_pkcs_register
1591 to const. Affected files are lib/silccrypt/silccipher.[ch],
1592 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1594 * Changed the silc_get_username and silc_get_real_name to
1595 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1597 * Fixed the Irssi SILC Client to use the silc_get_username and
1598 silc_get_real_name insted of glib routines since the glib
1599 routines only corrupt stack. Fixes the Irssi SILC to work in
1600 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1602 * Fixed the Irssi to not use g_get_home_dir since it crashes
1603 or returns garbage on cygwin and corrupts stack. Added function
1604 get_home_dir to Irssi routines. Affected files are
1605 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1607 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1609 * Made some structure optimizations. SFTP memory FS MemFSEntry
1610 entry structure. Optimized SilcTask structure. Optimized
1611 SilcPacketContext structure.
1613 Affected files lib/silcsftp/sftp_fs_memory.c,
1614 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1616 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1618 * And yet again reverted back the config thing since Johnny
1619 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1622 * Fixed memory leaks from config object. Affected files are
1623 silcd/serverconfig.[ch].
1625 * Added support for adding new connections to the server in rehash.
1626 After rehash they take effect.
1628 Added support for changing the maximum allowed connections in
1629 rehash. The number can grow but going smaller is not supported.
1631 Added function silc_server_num_sockets_by_remote to the
1632 silcd/server_util.[ch].
1634 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1636 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1638 * Added preliminary checking during config parsing for a valid
1639 public/private key and removed further checks in the code.
1640 Affected files are silcd/serverconfig.[ch], server.c.
1642 * Moved functions silc_server_drop() and silc_server_daemonise()
1643 from server.c to silcd.c since they are stricly related to
1644 the application activity.
1646 * Reverted a small part of the automatic ref/unref since
1647 it caused a double unref in some situations. Affected
1648 files are silcd/silcd.[ch], server.c, serverconfig.c.
1650 * Added some .cvsignore files in the lib directory.
1652 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1654 * Fixed silc_net_gethostbyaddr to correctly resolve by
1655 address. Affected file lib/silcutil/silcnet.c.
1657 * Fixed the notify relaying to client. The HMAC to be used
1658 with relayed packets ws wrong and caused decryption failure
1659 at the client end. Affected file is silcd/packet_receive.c.
1661 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1663 * Created new branch silc_protocol_1_0_branch.
1665 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1667 * Changed the silc_server_config_* routines to be SilcServer
1668 independent. They are now officially application specific code
1669 and not part of generic server implementation. Affected files
1670 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1672 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1674 * Added automatic referencing of config context in the
1675 silc_server_config_alloc, and automatic unreferencing in the
1676 silc_server_config_destroy. Affected files are
1677 silcd/serverconfig.[ch], silcd/silcd.c.
1679 * Fixed the silc_log_quick handling in the logging routines.
1680 It didn't log quickly when it was TRUE. Affected file is
1681 lib/silcutil/silclog.c. Also the flush delay was set even
1682 if it was 0 in config file. Affected file is
1683 silcd/serverconfig.c.
1685 * Added support for changing key pair of the server in rehash.
1686 Affected file silcd/server.c.
1688 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1690 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1691 too early, before getting the channel entry. Affected file
1692 is silcd/packet_receive.c.
1694 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1696 * Added functions silc_server_config_[ref/unref], these are used
1697 to prevent that the config object is destroyed.
1699 No longer directly affect global variables silc_log_quick and
1700 silc_log_delay, they are first cached inside the config object
1701 and then applied with silc_server_config_setlogfiles().
1703 silc_server_config_set_defaults() is now internal to
1704 serverconfig.c, there are no reasons to show this internal stuff
1707 Affected files are silcd/serverconfig.[ch].
1709 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1710 fprintf's to stderr, since some code may be executed again after
1711 the server went into the background. Affected files are
1714 * Added rehash support. Added function silc_server_rehash() that
1715 will perform all the basic tasks of the rehashing procedure.
1717 * Added command line option `-x, --hexdump'. This will enable the
1718 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1719 The option `--hexdump' implies `--debug'.
1721 * Fixed a bad bug in the logging APIs (silcutil library) where
1722 the application would crash after calling silc_log_reset_all().
1724 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1726 * Fixed the KICKED notify handling in client library to
1727 correctly remove the channel and all entries from the
1728 channel when I was kicked. This bug crashed the client.
1730 Fixed yet another but in KICKED notify handling to remove
1731 the kicked client correctly from the channel.
1733 Affected file is lib/silcclient/client_notify.c.
1735 * Fixed a minor bug in looking up correct client entry
1736 in KICKED notify in server. Affected file is
1737 silcd/packet_receive.c.
1739 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1740 sources correctly to distribution. Fixes --with-gmp option.
1742 * Removed the manual rehashing from ID Cache, and changed it
1743 to use the SILC Hash Table's auto rehash feature. Affected
1744 file is lib/silccore/silcidcache.c.
1746 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1748 * Fixed a bug in the silc_client_nickname_format function that
1749 handles the multiple same nickname formatting. Two clients
1750 with same nickname caused problems after the first one left
1751 and rejoined. It didn't format the nickname correctly.
1752 Affected file is lib/silcclient/idlist.c.
1754 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1756 * Don't change the topic if olod topic is same as new one.
1757 Affected file is silcd/packet_receive.c.
1759 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1761 * Added cross-reference support to the SILC Documentation
1762 generator. All types across all HTML files are now cross-
1763 referenced. Affected files util/robodoc/generator.c and
1764 scripts/silcdoc/silcdoc.
1766 * Added file lib/silcutil/silctypes.h to include all the
1767 arithmetic type definitions and some macros. Removed
1768 includes/bitmove.h and moved macros to silctypes.h.
1770 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1772 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1774 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1776 * Added `type' argument to silc_id_payload_parse_id function which
1777 now returns the type of the ID to the sent pointer. Affected
1778 file is lib/silccore/silcid.[ch].
1780 * Added check for CMODE_CHANGE notify type that mode change is
1781 allowed by the sender. Affected file silcd/packet_receive.c.
1783 * Added check for CUMODE_CHANGE notify type that mode change is
1784 allowed by the sender. Affected file silcd/packet_receive.c.
1785 Added the ID type as CUMODE_CHANGE notify type as argument
1786 to the `notify' client operation. Affected files are
1787 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1789 * Added function silc_client_add_server to the client library.
1790 Added support for resolving also channel and server info when
1791 received unknown entity in notify packet. Affected files are
1792 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1794 * Added function silc_command_get_status to return the command
1795 status from the command reply's argument payload. Affected files
1796 are lib/silccore/silccommand.[ch].
1798 * Added check for KICKED notify type that the kicking is
1799 allowed by the client. Affected file silcd/packet_receive.c.
1801 * Created function silc_get_input which can be used to get input
1802 (echo on or off) from user on command line. Affected files are
1803 lib/silcutil/silcutil.[ch].
1805 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1807 * Optimized silc_server_packet_relay_to_channel function.
1808 Added new function silc_channel_message_payload_encrypt which
1809 can be called directly if channel message payload needs to
1810 be encrypted and is already encoded (no need to call _encode
1811 function). Packet relaying is now done by router without any
1812 extra memory allocations. Affected files are
1813 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1814 silcd/packet_send.c.
1816 * Fixed the INVITE notify handling. It took wrong arguments
1817 as invite list and invite delete. Affected file is
1818 silcd/packet_receive.c.
1820 * Added check for TOPIC_SET notify type that the topic change is
1821 allowed by the client. Affected file silcd/packet_receive.c.
1823 * Added check for INVITE notify type that inviting is allowed by
1824 the client. Affected file silcd/packet_receive.c.
1826 * Changed the silc_server_client_on_channel to return the
1827 SilcChannelClientEntry as well. Moved the function
1828 silc_server_check_cmode_rights to server_util.[ch].
1829 Affected files are silcd/server_util.[ch], silcd/command.c.
1831 * Added function silc_server_check_umode_rights to check whether
1832 changing client's user mode is allowed. Added check for
1833 UMODE_CHANGE notify type that the umode change is allowed
1834 by the client. Affected files are silcd/server_util.[ch],
1835 silcd/packet_receive.c and silcd/command.c.
1837 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1839 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1840 ID length. It ignored that ID can be IPv6 based as well.
1841 Affected file lib/silccore/silcpacket.h.
1843 * Fixed the silc_id_id2str and silc_id_str2id to take the
1844 IPv6 address offset's into consideration. Affecte file is
1845 lib/silccore/silcid.c.
1847 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1849 * Fixed the internal Unix scheduler functions to check for
1850 NULL context they may receive. The affected file is
1851 lib/silcutil/unix/silcunixschedule.c.
1853 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1855 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1856 can specify different directory with --home command line
1857 parameter. Affected files irssi/src/silc/core/client_ops.c,
1860 * SILC-specific commands aren't now executed if the active server
1861 isn't of SILC-type, so there won't be problems with having
1862 IRC and SILC protocol support in same client. Affected files
1863 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1866 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1868 * Improved the signal support in SILC Schedule. Added new
1869 function silc_schedule_signal_call which is used by application
1870 to mark a signal to be called. It is now safe to perform
1871 any kind of tasks in signal callbacks since it is guaranteed
1872 that the application specified signal callback is called
1873 after the signal is over. Affected files are
1874 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1876 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1878 * Added `name' field to SilcChannelPrivateKey to represent
1879 application given name for the key. Moved also the context from
1880 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1881 Added the `name' argument also to the function
1882 silc_client_add_channel_private_key.
1884 Added function silc_client_current_channel_private_key to set the
1885 current channel private key in use.
1887 Added "change" command to KEY command which can be used to change
1888 the current channel private key. Bound the command also to
1889 alt+K (Alt+Shift+k).
1891 Also affected files lib/silcclient/client_channel.c,
1892 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1894 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1896 * Added silc_rng_get_byte_fast function in to the
1897 lib/silccrypt/silcrng.[ch].
1899 * Changed the interface of silc_packet_assemble and the
1900 silc_packet_send_prepare. If silc_packet_assmble is now
1901 called the application does not call silc_packet_send_prepare
1902 because the library will call it automatically. These
1903 interfaces now also return a reference to the outgoing buffer
1904 which includes the assembled packet, which the application can
1905 use to encrypt the packet.
1907 Affected files are lib/silccore/silcpacket.[ch],
1908 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1909 silcd/packet_send.c, server_backup.c and packet_receive.c.
1911 * Fixed a packet sending bug on very high load, where outgoing
1912 packet queue wasn't handled correctly and packets got corrupted.
1913 Affected files are lib/silcutil/*/silc*sockconn.c,
1914 lib/silcclient/client.c and silcd/server.c.
1916 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1918 * Added macro SILC_PACKET_DATALEN which can be used during
1919 packet assembling to check whether the data to be added to
1920 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1921 len is truncated until it fits it.
1923 Added checks for maximum length of channel message payload and
1924 private message payload also.
1926 Added checks for maximum packet length in server and in
1929 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1930 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1931 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1932 lib/silcclient/client_prvmsg.c.
1934 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1936 * Added silc_server_packet_queue_purge call to the
1937 silc_server_disconnect_remote to assure that all data in the
1938 queue before disconnecting is sent to the network. Affected
1939 file silcd/server.c.
1941 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1943 * Added the deleting of server's own ID cache entry to the
1944 silc_server_free function. Free also everything else that
1945 has been allocated in silc_server_init. The affected file
1948 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1950 * Added functions silc_parse_version_string, silc_version_to_num,
1951 and silc_ske_parse_version to parse SILC protocol style version
1952 strings. Affected files lib/silcutil/silcutil.[ch] and
1953 lib/silcske/silcske.[ch].
1955 * Added new configuration params: version_protocol, version_software
1956 and version_software_vendor to specify what version the remote
1957 host must at least be to be able to connect to server. The vendor
1958 string can be regex matched too. Added new function
1959 silc_server_connection_allowed to check maximum number of allowed
1960 connections, and allowed versions for incoming connections.
1961 Affected files are silcd/server.c, server_util.[ch] and
1964 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1966 * Added preliminary support for signals in scheduler. The
1967 signals we care about are now blocked always when the scheduler
1968 is locked. This way we can synchronise the use of signal with
1969 scheduler. It is guaranteed that when signal occurs the scheduler
1970 is not locked, and thus new tasks can be safely added to the
1973 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1974 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1975 Added new platform specific routines
1976 silc_schedule_internal_signals_[un]block and
1977 silc_schedule_internal_signal_[un]register.
1979 Added new functions to SILC Schedule API:
1980 silc_schedule_signal_[un]register. Each signal that application
1981 is going to use should be registered to the scheduler.
1983 Affected files are lib/silcutil/silcschedule.[ch],
1984 lib/silcutil/*/silc*schedule.c.
1986 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1988 * Check for unauthenticated client and server in the
1989 silc_server_new_client and silc_server_new_server functions.
1990 Affected file silcd/packet_receive.c.
1992 * Added function silc_string_is_ascii to check whether given
1993 string is 7-bit ASCII string. Affected files are
1994 lib/silcutil/silcutil.[ch].
1996 * Added function silc_id_is_valid_server_id into the
1997 silcd/serverid.c and added checking for valid Server ID's in
1998 silc_server_new_server. The Server ID must always be based
1999 on the server's public IP address.
2001 * Added logging of DISCONNECT packet message in the server.
2002 Affected file silcd/server.c.
2004 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2006 * Changed all library interfaces that use Global RNG to also
2007 accept SilcRng as argument. Affected files are
2008 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2009 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2010 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2011 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2012 lib/silccrypt/rsa.c.
2014 * Added function silc_pkcs_generate_key to the
2015 lib/silccrypt/silcpkcs.[ch] for applications so that they
2016 don't need to do pkcs->pkcs->init calls anymore.
2018 * Remove SilcSocketConnection from the SFTP API since it really
2019 wasn't needed there. The application has the information
2020 saved in its contexts anyway and the SFTP layer doesn't need
2021 know about it. Affected files lib/silcsft/silcsftp.h and
2022 lib/silcsftp/sftp_[server/client].c.
2024 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2025 The SilcSimContext is not SilcSim.
2027 * Fixed possible buffer overflows in silc_id_render in the
2028 lib/silcutil/silcutil.c.
2030 * On EPOC the global crypto module lists are not used at all
2031 in the crypto library. Added support for using the constant
2032 algorithm list on EPOC. Affected files are
2033 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2036 * Fixed the handling of third parameter of KICKED notify, since
2037 it was mistakenly updated to SILC Protocol 1.0 even though it
2038 is to be included in 1.1. Since it is not in 1.0 it is not
2039 mandatory, and this fix now handles it only if it is provided,
2040 and it is not error if it is not provided. Affected file
2041 lib/silcclient/client_notify.c.
2043 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2045 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2046 client. Affected file irssi/src/silc/core/client_ops.c.
2048 * Merged with Irssi 0.8.4 from irssi.org CVS.
2050 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2052 * Check for valid socket connection in client entries before
2053 sending any messages. Fixes a crash, but doesn't fix some
2054 other underlaying bug that is lurking there. Affected
2055 file silcd/packet_send.c.
2057 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2059 * $usermode, $cumode and $cumode_space expandos shouldn't do
2060 anything with non-SILC server records. Affected file
2061 irssi/src/silc/core/silc-expandos.c
2063 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2065 * Fixed the silc_net_check_[host/local]_by_sock to support
2066 IPv6 bound sockets as well. Now they can return IPv6 addresses
2067 as well. Affected file lib/silcutil/silcnet.c.
2069 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2070 Affected lib/silcutil/unix/silcunixnet.c.
2072 * Fixed ID rendering (at least on some platforms, not NetBSD)
2073 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.

2080 file lib/silcutil/silcutil.[ch].
2082 * Added support for specifying multiple public keys for Client
2083 connection section in server configuration file. This makes it
2084 possible to accept multiple public keys from same host, or to
2085 make a section that accepts any incoming host, and have the
2086 accepted public keys listed in the section.
2088 Added functions silc_sever_[find/get]_public_key, added the
2089 support for this actually to all connection sections but only
2090 the Client section is currently allowed to specify multiple

2201 old name went against naming convention. Applications now
2202 include "silcclient.h" instead of "clientlibincludes.h".
2203 Removed includes/clientlibincludes.h, it is redundant now.
2205 * Renamed includes/version.h to silcversion.h.
2207 * Added really preliminary support for OS/2 into the util
2208 library. Only thread & mutex API is implemented, others

2243 * Added `user_count' to the SilcChannelEntry which now tells the
2244 number of users on the channel. The user count is now saved
2245 in normal server of global channels as well. Affected files
2246 silcd/server.c, idlist.h, packet_receive.c and command.c.
2248 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2249 include file utility functions.
2251 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2252 instead of calling directly OS routines.

2265 the SKE interface a bit.
2267 * Fixed padding problem in PKCS#1. The padding was not actually
2268 random since the random number generator was used incorrectly.
2269 This security bug affects only when encrypting with PKCS#1, and
2270 it is not currently used at all in SILC. SILC only use signing
2271 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2334 Affected files irssi/src/silc/core/silc-core.c,
2335 irssi/src/fe-text/silc.c.
2337 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2339 * Added new configuration options and blocks:
2340 keepalive_secs, reconnect_count, reconnect_interval,
2341 reconnect_interval_max, reconnect_keep_trying and

2356 the connection configuration object from the SilcServerConnection
2357 object instead of finding it during the connecting phase.
2358 Added the configuration object to SilcServerConnection struct.
2359 Affected files silcd/server_internal.h, server.c.
2361 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2363 * Add the client on channel after it was resolved at the
2364 channel message receiving, and it was not already on the
2365 channel. Affected file lib/silcclient/client_channel.c.
2367 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2383 authentication to be set at the same time.
2385 Added `prefer_passphrase_auth' setting in config file which
2386 can be used to set to prefer passwd auth if both passwd and
2387 public key is set. If not set, public key is preferred.
2388 This has effect only when being initiator (responder will try
2391 Added support for authentication with passphrase and public key
2392 at the same time. The passphrase is tried first always since
2393 it is faster to check.
2395 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2397 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2443 * Fixed the file transfer's key agreement payload to include
2444 zero port also if the hostname is NULL because it could not
2447 Call file transfer monitor callback now also if error occurs
2448 during key agreement protocol.
2450 Changed the silc_client_file_send interface to return the
2451 SilcClientFileError instead of session id. The session ID
2452 is returned into pointer provided as argument.

2467 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2468 SILC_LOG_WARNING to give out Warning and not Error. Affected
2469 file lib/silcutil/silclog.c.
2471 * Fixed the channel message payload decryption in the function
2472 silc_channel_message_payload_decrypt to not modify the original
2473 buffer before it is verified that the message decrypted
2474 correctly. Otherwise, next time it is called with correct
2475 channel key it won't encrypt since the payload is corrupted.
2476 Affected file lib/silccore/silcchannel.c.
2478 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2491 the table with foreach callback. The current entry may
2492 become invalid in the callback but it was referenced after
2493 the callback returned.
2495 Do not allow auto rehashing of hash table during the
2496 silc_hash_table_foreach operation, for same reasons as it is
2497 not allowed for SilcHashTableList. Affected files are
2498 lib/silcutil/silchashtable.[ch].
2500 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2521 users list to SilcHashTable. The affected files are
2522 lib/silcclient/idlist.[ch].
2524 * Fixed a bug in hash table tarversing. While the hash table
2525 is traversed with SilcHashTableList the table must not be
2526 rehashed. It is now guaranteed that auto rehashable tables
2527 are not rehashed while tarversing the list. Also defined that
2528 silc_hash_table_rehash must not be called while tarversing
2529 the table. Added function silc_hash_table_list_reset that must
2530 be called after the tarversing is over. The affected files are
2531 lib/silcutil/silchashtable.[ch].
2533 * Changed all hash table traversing to call the new
2534 silc_hash_table_list_reset in server and in client library.
2536 * Added function silc_client_on_channel to return the
2537 SilcChannelUser entry if the specified client entry is joined
2538 on the specified channel. This is exported to application as
2539 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2544 server. The notify for mode change must be sent always and
2545 not only if !cmd->pending. Affected file silcd/command.c.
2547 * Fixed the WHOWAS command's reply sending to support the
2548 lists correctly. Affected file silcd/command.c.
2550 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2552 * When sending JOIN command to router for processing the
2553 sender's old command identifier was not saved back to the
2554 sender's command context, fixed now. The affected file is
2557 * Create the key in JOIN command of the router did not return
2558 the channel key, added check for this. Affected file is
2561 * Fixed a channel ID update bug in JOIN command reply. Do
2562 not directly upgrade the ID but call the function
2563 silc_idlist_replace_channel_id if the ID was changed.
2564 Affected file silcd/command_reply.c.
2566 * Fixed memory leaks from command calling if it would fail.
2567 Affected file silcd/command.c.

2579 * Removed TRQ from lib/trq, not needed anymore.
2581 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2582 with server connections. Later this will be configurable
2583 in config file after new config file is done. Affected file
2586 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2588 * Fixed a crash in server related to channel announcements.

2594 functions. Affected file silcd/server.c.
2596 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2597 which ID was changed. This way the router will send the
2598 user list for the channel again, and server won't be in
2599 desync in some rare circumstances. Affected file is
2600 silcd/packet_receive.c.
2602 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2604 * Check for NULL socket pointer in the function
2605 silc_server_packet_send_to_channel_real. Affected file
2606 silcd/packet_send.c.
2608 * Fixed the BAN notify handling to correctly remove ban
2609 list. Affected file silcd/packet_receive.c.
2611 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2613 * Fixed some header addition to Toolkit distribution in
2614 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2616 * Added lib/silcclient/client_ops_example.h as an template
2617 file for application programmers to quickly start using
2618 the SilcClientOperation functions in their application.
2619 Updated the lib/silcclient/README as well to tell about this
2620 nice file made available.
2622 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2624 * Call silc_server_remove_from_channels when removing client
2625 entry when NO_SUCH_CLIENT_ID was received. Affected file
2626 is silcd/command_reply.c.
2628 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2630 * Added server & router operator statistics updating. Affected
2631 file silcd/packet_receive.c and silcd/command.c.
2633 * Fixed the SERVER_SIGNOFF notify handling on normal server
2634 not to save the history information for clients. Same was
2635 fixed earlier in remove_clients_by_server function, but not
2636 here. Affected file silcd/packet_receive.c.
2638 * Raised the default connection-retry count from 4 to 7 in
2639 server. Affected file silcd/server.h.
2641 * Cancel any possible reconnect timeouts when we start the
2642 key exchange. Affected file silcd/server.c.
2644 * Do not reconnect on connection failure when SCONNECT was
2645 given. Affected files silcd/server.[ch].
2647 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2649 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2651 * Fixed the NICK command to always give the unformatted
2652 nickname to the one giving the NICK command. If unformatted
2653 nickname is cached already it will be formatted and the
2654 local entry will always get the unformatted nickname.
2655 Affected file lib/silcclient/idlist.c.
2657 * Fixed some double frees from client library commands.
2658 Affected file is lib/silcclient/command.c.
2660 * Fixed CUMODE command in server to assure that no one can
2661 change founder's mode than the founder itself, there was a
2662 little bug. Affected file silcd/command.c.
2664 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2666 * Removed the SilcClientCommandDestructor from the client
2667 libary, it is not needed anymore. Affected files are
2668 lib/silcclient/silcapi.h, command[_reply].[ch],
2669 client_notify, idlist.c.
2671 * Fixed GETKEY command to first resolve client, and then
2672 resolve the server only if the client was not found, instead
2673 of resolving both at the same time. Affected file is
2674 lib/silcclient/command.c.
2676 * Added silc_client_start_key_exchange_cb and lookup the
2677 remote hostname and IP address before starting the key
2678 exchange with server. The affected file is
2679 lib/silcclient/client.c.
2681 * The server's public key is now saved using the IP address
2682 of the server and not the servername for the filename.
2683 The hostname public key filename is checked as an fall back
2684 method if the IP address based filename is not found.
2686 Fixed the GETKEY command to save the fetched server key
2687 in correct filename.
2689 Print the remote server's hostname now when new key is
2690 received during connection process. Affected file is
2691 irssi/src/silc/core/client_ops.c.
2693 * Return always our own public key to the client if it asks
2694 for it with GETKEY command. Affected file silcd/command.c.
2696 * Removed the use_auto_addr variable from default config
2697 file since it was in wrong section. Affected file is
2700 * Fixed TOPIC_CHANGE notification to not route it when it
2701 was sent using silc_server_send_notify_to_channel function.
2702 Affected file silcd/command.c.
2704 * Fixed silc_server_send_notify_kicked to send the kicker's
2705 Client ID also, it was missing. Affected files are
2706 silcd/command.c, silcd/packet_send.[ch].
2708 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2710 * Do not save client history information in SERVER_SIGNOFF.
2711 Fixes the bug in normal server that it does not detect
2712 the client becoming valid after the server becomes back
2713 online. Affected file silcd/server_util.c.
2715 * Added `sock_error' field into the SilcSocketConnection
2716 context. When error occurs during socket operation (read
2717 or write) the error is saved. Added also new function
2718 silc_socket_get_error to return human readable socket error
2719 message. Affected files are lib/silcutil/silcsockconn.[ch],
2720 lib/silcutil/unix/silcunixsockconn.c, and
2721 lib/silcutil/win32/silcwin32sockconn.c.
2723 * The server now prints the socket error message in the
2724 signoff for client. Affected file silcd/server.c.
2726 * Fixed the `created' channel information sending from router
2727 to server in JOIN command. Checks now whether the channel
2728 really was created or not and set it according that.
2730 Fixed the JOIN command to use the client entry's current
2731 ID during the joining procedure instead of the one it sent
2732 in the command (it is checked though), since it can change
2733 between the packet processing and command processing, and
2734 would just case unnecessary pain in the client end. Affected
2735 file silcd/command.c.
2737 * Fixed a channel key payload sending to use correct channel
2738 ID when the server was forced to change the channel's ID by
2739 router. Router sent the key payload with the old Channel ID.
2740 Affected file silcd/packet_receive.c.
2742 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2744 * Call silc_server_save_channel_key only if the key payload
2745 was provided in the JOIN command's command reply. Affected
2746 file silcd/command_reply.c.
2748 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2750 * Fixed silc_mp_sizeinbase to return the value correctly with
2751 MPI. Affected file lib/silcmath/mp_mpi.c.
2753 * Fixed the stop_server signal to correctly stop the scheduler
2754 and gracefully stop the server when SIGTERM or SIGINT signals
2755 are received. Affected file silcd/silcd.c.
2757 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2759 * Simple handling of TERM and HUP signals. Also added some log
2760 flushing call around. Affected file is
2763 * Fixed small bugs in silclog.c. Now buffering output will take
2764 effect after 10 seconds since startup: This will ensure that
2765 no important startup messages are lost. Also output redirection
2766 will preserve original format ([Date] [Type] message).
2767 Affected file is lib/silcutil/silclog.c.
2769 * Added two options to the config file, in the logging section:
2770 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2771 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2773 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2775 * Do not print the warning about log files not being initialized
2776 more than once to avoid excess logging. Affected file is
2777 lib/silcutil/silclog.c.
2779 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2780 the SIM copying in make install in Makefile.am.pre.
2782 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2784 * Rewritten silclog APIs. Globally interesting changes follows:
2785 silc_log_set_files() changed to silc_log_set_file().
2786 silc_log_set_callbacks() changed to silc_log_set_callback().
2787 ROBOdoc documented silclog header file.
2788 SilcLogCb now returns bool to wether inihibit the default
2789 handler or not (to keep the old behaviour return always TRUE).
2790 The new APIs should also fix the problem of the
2791 silcd_error.log file that was written in the current directory.
2794 Log files streams will remain opened after silc_log_set_file()
2795 call, means less CPU usage notably on high traffic servers.
2796 File streams are now full buffered, and flushed to the disk
2797 every 5 minutes, lesses HD activity and CPU usage.
2798 Messages can be redirected, allowing admins to configure
2799 one single logfile for all server messages.
2800 the silc_log_quick global variable to activate fast-logging.
2801 Affected files lib/silcutil/silclog.[ch]
2803 * Changed some code to conform new silclog APIs. Affected
2804 files are doc/example_silcd.conf.in, silcd/server.c
2805 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2808 * Fixed a memory leak that could occur in some situations.
2809 Affected file silcd/serverconfig.c.
2811 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2813 * Added the silc_client_del_client to remove the client from
2814 all channels as well. Affected file lib/silcclient/idlist.c.
2816 * Fixed the client library to correctly remove the client
2817 from all channels when the client entry is being destroyed.
2818 Affected file lib/silcclient/client_notify.c, command.c.
2820 * Added auto-nicking support to the client library. If the
2821 applicatio now sets client->nickname it will be sent to the
2822 server after connecting by the library. This way for example
2823 SILCNICK (or IRCNICK) environment variables will have effect
2824 and always change the nickname automatically to whatever
2825 it is wanted. Affected file lib/silcclient/client.[ch].
2827 * Renamed silc_server_command_bad_chars to the
2828 silc_server_name_bad_chars and moved it to the
2829 silcd/server_util.[ch]. Added also new function
2830 silc_server_name_modify_bad to return nickname that
2831 includes bad characters as new nickname without those
2832 bad characters. This check and modify is now used in
2833 silc_server_new_client when the username is initially set
2834 as nickname, so it must be checked to be valid nickname.
2835 Affected file silcd/packet_receive.c.
2837 * The nickname length is now taken from the packet for real
2838 and not trusted to strlen() since it clearly can return
2839 wrong length for nickname including bad characters. This
2840 also applies to channel names. Affected file silcd/command.c.
2842 * Removed the lib/silcsilm/modules directory. Modules are now
2843 compiled into the lib/silcsim. Fixed the copying of the
2844 modules to follow symbolic links in Makefile.am.pre.
2846 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2848 * Fixed silc_string_regexify list creation. Fixes bugs with
2849 BAN and INVITE commands in server. The affected file is
2850 lib/silcutil/unix/silcunixutil.c.
2852 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Removed the command destructor entirely from the server's
2855 command and command reply routines. It is not needed, and
2856 its usage was buggy and caused crashes. Affected files are
2857 silcd/command[_reply].[ch].
2859 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * Cancel protocol and NULL sock->protocol if timeout
2862 occurred during protocol. Affected file silcd/server.c.
2864 * Cancel protocol timeouts always before calling the final
2865 callback, to assure that after final callback is called
2866 no other state will be called for the protocol anymore.
2867 Affected file silcd/protocol.c.
2869 * Print error log if incoming connection configuration could
2870 not be found. Affected file silcd/server.c.
2872 * Fixed JOIN command to correctly save the founder mode
2873 to the client on normal SILC server, when the channel
2874 was created by the router. Affected file silcd/command.c.
2876 * Fixed LIST command (hopefully) to send correct reply
2877 packets. Affected file silcd/command.c.
2879 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * The silc_packet_receive_process now returns FALSE if the
2882 read data was invalid packet, and TRUE if it was ok.
2884 The server now checks that if unauthenticated connection
2885 sends data and its processing fails the server will close
2886 the connection since it could be a malicious flooder.
2888 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2890 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Make sure the warning about error opening a log file is
2893 printed only once and not everytime it fails (produces
2894 too much useless log). Affected file lib/silcutil/silclog.c.
2896 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2898 * Made the silc_server_daemonise() function more readable.
2899 Affected file silcd/server.c.
2901 * Pid file is now optional, the user may comment it out from
2902 the config file. Removed define SILC_SERVER_PID_FILE, we
2903 don't need a default any longer. Affected file
2904 configure.in.pre, lib/Makefile.am.pre.
2906 * Make some use of the pid file. The server now dies at startup
2907 if it detects a valid pid file on his path. The server would
2908 die anyway in this circumstance, because of the bind() failure.
2909 Affected file silcd/silcd.c.
2911 * No longer compiling lib/dotconf.
2913 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Fixed JOIN command parsing not to crash. Affected file
2916 lib/silcclient/command.c.
2918 * Fied the NICK_CHANGE notify to add the new client entry
2919 even it is resolved. This removes an <[unknown]> nick
2920 thingy bug in the client. Affected file is
2921 lib/silcclient/client_notify.c.
2923 * Do not try to allocate 0 bytes (efence does not like it)
2924 in lib/silccore/silccomand.c when encoding payload.
2926 * Do not take IRCNICK as nickname in Irssi SILC client since
2927 it is not possible to set nickname before hand connecting
2928 the server (TODO has an entry about adding auto-nicking
2931 * Changed the silc_server_command_pending to check whether
2932 there already exists an pending entry with the specified
2933 command, command identifier and pending callback. This is
2934 to fix IDENTIFY and WHOIS related crashes that may register
2935 multiple pending commands with same identifier. Affected
2936 file silcd/command.c.
2938 * Fixed the server to reconnect to the router even if it
2939 was already reconnecting and EOF was received. This to
2940 fix a possibility that the server wouldn't ever try to
2941 auto-reconnect to the router. Affected file silcd/server.c.
2943 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Fixed the server's password authentication to use the
2946 length of the locally saved password, and not the one
2947 sent in the packet. Affected file silcd/protocol.c.
2949 * Fixed same password authentication problem in the
2950 Authentication Payload handling routines in
2951 lib/silccore/silcauth.c.
2953 * Yet another password authentication problem fixed with
2954 channel password handling in silcd/command.c.
2956 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * If first character of string in silc_parse_userfqdn is '@'
2959 then do not parse it. Affected file is
2960 lib/silcutil/silcutil.c.
2962 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Fixed minor bug in IDENTIFY command reply sending, which
2965 caused various weird problems during JOIN when it was
2966 resolving names for users. Affected file silcd/command.c.
2968 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Fixed the IDENTIFY command reply sending to chech better valid
2971 clients. It was possible to send incomplete list of replies.
2972 Affected file silcd/command.c.
2974 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Added silc_client_command[s]_[un]register functions now to
2977 dynamically register the commands in client library. Removed
2978 the static table of commands. This allows the client library
2979 to call commands without causing the application to know about
2980 what commands library has called.
2982 Removed the INFO command reply kludge to detect when the command
2983 was called by library. Now library use its own command reply
2984 function for INFO command.
2986 Added function silc_client_command_call to call a command.
2987 Application can use it to call command, not access the structure
2990 Now all commands that are sent by the client library (not
2991 explicitly sent by application) use own command reply functions.
2993 Affected files around lib/silcclient/ and in
2994 irssi/src/silc/core/.
2996 * Fixed the WHOIS command reply sending to chech better valid
2997 clients. It was possible to send incomplete list of replies.
2999 Fixed the WHOIS and IDENTIFY to send the request to router
3000 if normal server did not do it and did not find any results.
3002 Affected file silcd/command.c.
3004 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Moved the internal data from SilcClient context into its
3007 own file, not accesible to application. Affected files
3008 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3009 and other files in client library.
3011 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Added doc/examples installation target in Makefile.am.pre.
3016 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3019 commands the found client entry will be removed from the
3020 cache, after notifying application about the error. Affected
3021 file lib/silcclient/command_reply.c.
3023 * Changed the /MSG to check for exact nickname user gave, and
3024 not let `nick' match `nick@host' if it is only one found. Now,
3025 user must type the exact nickname (like nick@host2) even if
3026 there are no more than one same nicks found. This is to avoid
3027 a possibility of sending nickname to wrong nickname since
3028 `nick' could match `nick@host'. Affected file is
3029 irssi/src/core/silc-servers.c.
3031 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Do not print "you are now server operator" or similar when
3034 giving /away command. Affected files are
3035 irssi/src/silc/core/client_ops.c, silc-servers.h.
3037 * Made the silc_server_command_pending_error_check to send
3038 the same command reply payload it received back to the
3039 original sender of the command. This way all arguments
3040 that was received by the server will be received by the
3041 client too. Affected file silcd/command.c.
3043 * Added the silc_idcache_add to return the created cache entry
3044 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3046 * Add global clients to expire if they are not on any channel.
3047 This is because normal server will never know if they signoff
3048 if they are not on any channel. The cache expiry will take
3049 case of these entries. This is done by normal servers only.
3050 The affected files are silcd/command_reply.c,
3051 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3053 * If server receives invalid ID notification for WHOIS or
3054 IDENTIFY and the ID exists in the lists, it is removed.
3055 Affected file silcd/command_reply.c.
3057 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3058 in client then client entry that it matches is searched and
3059 the nickname is printed on the screen for user. Affected
3060 file irssi/src/silc/core/client_ops.c.
3062 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3064 * Use cache entry expire time in the LIST command reply to
3065 purge old entries from the cache after the LIST command
3066 reply has been received. This way we don't have non-existent
3067 entries in the cache for too long. Affected file is
3068 silcd/command_reply.c.
3070 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * If we are normal server, and we've not resolved client info
3073 in WHOIS or IDENTIFY from router, and it is global client,
3074 we'll check whether it is on some channel. If it is not
3075 then we cannot be sure about its validity and will resolve it
3076 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3077 file silcd/command.c.
3079 * Search channel by name (if possible) rather than by ID
3080 in IDENTIFY command's command reply. Affected file is
3081 silcd/command_reply.c.
3083 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3086 Updated specs and implemented it. Affected file silcd/command.c,
3087 silcd/packet_send.c and silcd/packet_receive.c.
3089 * Implemented the <founder auth> payload handling in the JOIN
3090 command. If provided all conditions for channel joining
3091 except requirement to provide correct passphrase can be
3092 overrided by the channel founder. Updated the protocol specs.
3093 Affected file silcd/command.c.
3095 Added support for founder auth in JOIN command in client
3096 library. Fixed the parsing of the JOIN command now to support
3097 all options as they should be. The affected file is
3098 lib/silcclient/command.c.
3100 * Optimized the WHOIS and IDENTIFY commands to send the request
3101 to router only if it includes nicknames or other names. If
3102 they include only IDs then check the local cache first before
3103 routing. Affected file is silcd/command.c.
3105 * Added channels topic announcements. Affected file is
3106 silcd/packet_receive.c and silcd/server.c.
3108 * Fixed the silc_server_send_notify_topic_set to really destine
3109 the packet to channel. Affected file silcd/packet_send.c.
3111 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3112 library. Affected file lib/silcclient/client_notify.c.
3114 * Added UMODE announcements. Affected file silcd/server.c.
3116 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Memory leak fixes in:
3120 lib/silcutil/silcsockconn.c
3121 lib/silcske/silcske.c
3122 lib/silcske/groups.c

3125 lib/silccore/silccommand.c
3126 lib/silccore/silcidcache.c
3131 * ROBOdoc documented the lib/silcske/groups.h file and a
3132 bit changed the interface for better.
3134 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3136 * Update the client entry context in the ID cache after
3137 nick change. Affected file lib/silcclient/command.c.
3138 Fixes the CUMODE command when regaining founder privileges,
3139 and a little WHOIS problem.
3141 * Fixed silc_net_gethostbyname to correctly call the
3142 inet_ntop. Affected file lib/silcutil/silcnet.c.
3144 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3146 * Added IPv6 support checking to the configure.in.pre, added
3147 also --enable-ipv6 option to override the check. Affected
3148 file configure.in.pre.
3150 * The silc_thread_create now calls the start function
3151 directly if threads support is not compiled in. Removes
3152 ugly #ifdef's from generic code. Affected files are
3153 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3155 * Added silc_net_gethostby[name/addr]_async to asynchronously
3156 resolve. Affected files are lib/silcutil/silcnet.[ch].

3174 * Fixed LIST command reply sending in server. Affected file
3177 * Server now sends the kicker's client ID in the KICK notify
3178 to the kicked client. Affected file silcd/command.c.
3180 * The client library now parses the kickers client ID and
3181 UI displays it. Affected files lib/silcclient/client_notify.c
3182 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3184 * Made all payload parsing function prototypes consistent.
3185 They all take now const unsigned char * and uint32 pair as
3186 the payload data instead of SilcBuffer. Changes all around
3187 the source tree. Other unsigned char* -> const unsigned char*
3188 changes around the tree as well.
3190 * Optimized SFTP client and server packet sending not to
3191 allocate new buffer for each packet but to recycle the
3192 first allocated buffer. Affected files are
3193 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3195 * Optimized the SFTP client to use SilcList instead of
3196 SilcDList for requests, because it is faster. Affected file
3197 is lib/silcsftp/sftp_client.c.
3199 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3200 into lib/silccore/silcid.[ch].
3202 Renamed silcpayload.[ch] into silcargument.[ch].
3204 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * If client entry is deleted with active key agreement
3207 session, abort the session.
3209 The silc_client_abort_key_agreement now calls the completion
3210 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3212 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3215 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Don't use __restrict in older GCC's. Affected file is
3218 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3220 * silc_net_localhost now attempts to reverse lookup the
3221 IP/hostname. Affected file lib/silcutil/silcnet.c.
3223 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3224 command. It can be used to gain founder privileges at
3225 the same time when joining the channel.
3227 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3228 kicker's client ID as well. Updated protocol specs.
3230 Defined that the server must send SILC_COMMAND_IDENTIFY
3231 command reply with error status to client who sent
3232 private message with invalid client ID.
3234 Updated the protocol specification.
3236 * Added silc_server_send_command_reply to send any
3237 command reply. Affected file silcd/packet_send.[ch].
3239 * Added silc_id_payload_encode_data to encode ID payload
3240 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3242 * The server now send IDENTIFY command reply with error
3243 status if client ID in private message is invalid. Affected
3244 file silcd/packet_receive.c.
3246 * Save the server key file with server's IP address in
3247 the filename instead of hostname. The affected file is
3248 irssi/src/silc/core/client_ops.c.
3250 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3252 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3255 * Added libtool support for compiling shared objects in
3256 lib/silcsim. Affected file configure.in.pre and
3257 lib/silcsim/Makefile.am. Original patch by cras.
3259 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Pid file configuration, and server's config file fixes
3262 patch by toma. Updated CREDITS file.
3264 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3266 * Fixed silc_client_channel_message to not try to decrypt
3267 the message twice if it resolved the destination client
3268 information. This could cause of dropping one channel
3269 message. Affected file lib/silcclient/client_channel.c.
3271 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3274 lib/silcclient/client.c. This function is used when the SILC
3275 Client is run under some other scheduler, or event loop or
3276 main loop. On GUI applications, for example this may be
3277 desired to used to run the client under the GUI application's
3278 main loop. Typically the GUI application would register an
3279 idle task that calls this function multiple times in a second
3280 to quickly process the SILC specific data.
3282 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3284 * Fixed silc_server_drop() for dropping the supplementary
3285 groups as well, this could cause a security hole on some
3288 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3293 * Write PID file after dropping privileges. Added -F option
3294 to run server on foreground. A patch by debolaz.
3295 Affected files silcd/server.c, silcd/silcd.c.
3297 * Fixed MOTD to return the MOTD file server name. Affected
3298 file silcd/command.c.
3300 * Added INFO command reply handling to the Irssi SILC Client.
3301 Affected file irssi/src/silc/core/client_ops.c.
3303 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Fixed the silc_idcache_list_* routines to really support
3306 the dynamic list. Fixes a crash. Affected file is
3307 lib/silccore/silcidcache.c.
3309 * Fixed the LIST command reply to really call LIST command's
3310 pending callbacks. Affected file silcd/command_reply.c.
3312 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * Update conn->local_entry->nickname after giving NICK
3315 command. Affected file lib/silcclient/command.c.
3317 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3319 * Added the [pid] option to the silcd configuration file
3321 Affected files: serverconfig.[ch] and silcd.c
3323 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Save fingerprint in WHOIS command reply in server.
3326 Affected file silcd/command_reply.c.
3328 * Fixed NICK commands pending callback registration.
3329 Affected file lib/silcclient/command.c.
3331 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Use ++server->cmd_ident when sending commands in server,
3334 instead of random number. Affected file silcd/command.c.
3336 * Fixed GETKEY command reply to call actually GETKEY pending
3337 command callbacks. Affected file silcd/command_reply.c.
3339 * A bit stricter check for nicknames. Check for same nickname
3340 in NICK command also. Affected file silcd/command.c.
3342 * Do not call INFO command everytime client ID changes, only
3343 during first connecting. Affected file lib/silcclient/client.c.
3345 * Set the new nickname only after successful command reply for
3346 NICK command is returned by server. Affected file
3347 lib/silcclient/command.c.
3349 * Remove nicknames from nicklist during server_signoff notify.
3350 Should fix /NAMES bit more. The affected file is
3351 irssi/src/silc/core/silc-channels.c.
3353 * Added `fingerprint' field to the SilcIDListData in the
3354 silcd/idlist.h to hold the fingerprint of the client's
3357 Send the fingerprint of the client's public key in WHOIS
3360 Affected files silcd/command.c, and silcd/idlist.[ch].
3362 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3363 create fingerprint from given data.
3365 * Show the fingerprint of the client's public key in WHOIS.
3366 Affected files irssi/src/module-formats.[ch] and
3367 irssi/src/silc/core/client_ops.c.
3369 * Format the multiple same nicknames also during JOIN and
3370 NICK_CHANGE notifys. Affected file is
3371 lib/silcclient/client_notify.c.
3373 * Do not print error on screen for invalid private message
3374 payload since it can come if someone is sending private
3375 messages with wrong key. Affected file
3376 lib/silccore/silcprivate.c.
3378 * Fixed multiple concurrent /PING crash. Affected file
3379 lib/silcclient/command.c.
3381 * Changed the wrong ID encoding. All IP addresses must be
3382 in MSB first order in encoded format. They were encoded
3383 wrong and was in LSB format. Affected files are
3384 silcd/serverid.c, lib/silcutil/silcutil.c.
3386 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3388 * Call the `connect' client operation through the scheduler
3389 in case of error. Affected file lib/silcclient/client.c.
3391 * Call the `failure' client operation even if the error
3392 occurred locally during a protocol. Affected file is
3393 lib/silcclient/protocol.c.
3395 * Added support of sending LIST command to router from normal
3396 server. This way normal server can get list of all channels
3397 in the network too. Fixed the channel list sending in the
3398 server too. Affected files are silcd/command.c, and
3399 silcd/command_reply.[ch].
3401 * Added silc_server_update_channels_by_server and
3402 silc_server_remove_channels_by_server. They are used during
3403 disconnection of primary router and in backup router protocol.
3404 Affected file silcd/server_util.[ch], silcd/server.c and
3405 silcd/server_backup.c.
3407 * Fixed channel adding to global list in IDENTIFY command
3408 reply in server. Affected file silcd/command_reply.c.
3410 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * If the incoming packet type is REKEY or REKEY_DONE process
3413 that packet always synchronously. Fixes yet another MAC
3414 failed error on slow (dialup) connections. Affected file
3415 lib/silcclient/client.c and silcd/server.c.
3417 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3419 * Call check_version SKE callback for initiator too. Affected
3420 file lib/silcske/silcske.c.
3422 * Implemented fix for security hole found in the SKE that was
3423 fixed in the specification few days back; the initiator's
3424 public key is now added to the HASH value computation.
3425 Added backwards support for the old way of doing it too, for
3426 old clients and old servers. Affected file is
3427 lib/silcske/silcske.c.
3429 * Enabled mutual authentication by default in SKE. If initiator
3430 is not providing mutual authentication the responder will
3431 force it. This will provide the proof of posession of the
3432 private key for responder. The affected files are
3433 lib/silcclient/protocol.c and silcd/protocol.c.
3435 * Do not cache anymore the server's public key during SKE.
3436 We do mutual authentication so the proof of posession of
3437 private key is done, and if the server is authenticated in
3438 conn auth protocol with public key we must have the public
3439 key already. Affected file silcd/protocol.c.
3441 * Added new global debug variable: silc_debug_hexdump. If
3442 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3443 file lib/silcutil/silclog.[ch].
3445 * Fixed compilation warning due to char * -> const char *.
3446 Affected files lib/silcutil/silcnet.h, and
3447 lib/silccore/silcauth.[ch].
3449 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3451 * Fixed CMODE command when new channel key was created. If
3452 the creation failed the old key was removed. Next time giving
3453 same command would crash the server since the old key was
3454 freed already. Affected file silcd/command.c.
3456 * Fixed the silc_server_announce_get_channels to not crash
3457 on reconnect. Affected file silcd/server.c.
3459 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Added silc_log_set_debug_string function to set a regex
3462 string to match for debug output. Only the function names,
3463 or filenames matching the given debug string is actually
3464 printed. This way it is possible to filter out those debug
3465 strings that user is not interested in.
3467 Fixed a bug in silc_string_regexify.
3469 Affected files lib/silcutil/silclog.[ch], and
3470 lib/silcutil/unix/silcunixutil.c.
3472 * Changed the -d options in both server and Irssi SILC client
3473 to take the debug string as argument. Affected files
3474 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3476 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Added silc_hash_babbleprint to create a Bubble Babble
3479 Encoded fingerprint. The encoding is developed by Antti
3480 Huima (draft-huima-babble-01.txt), and it creates human
3481 readable strings out of binary data. Affected file
3482 lib/silccrypt/silchash.[ch].
3484 * Print the babble print now in addition of fingerprint as well
3485 in Irssi SILC client. Affected files are
3486 irssi/src/fe-common/silc/module-formats.[ch],
3487 irssi/src/fe-common/silc/core/client_ops.c.
3489 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Fixed a security problem found in SKE. The initiator's
3492 public key too is now added to the HASH hash value creation
3493 which is signed by the responder to create the SIGN value.
3494 This will prevent anyone in the middle to lie to the responder
3495 about the initiator's public key. If this is done now, the
3496 man in the middle will get caught. Updated the protocol
3499 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Better installation directory handling. Configure module
3502 paths and other paths automatically to example_silc* files
3503 in doc/. A patch by toma.
3505 * Fixed compiler warning from MPI library, and from SILC RNG.
3508 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3509 It can be configured with ./configure. A patch by toma.
3511 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3513 * Find correct make to use in prepare-clean. A patch by
3514 toma. Affected file prepare-clean.
3516 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3518 * Added irssi variables use_auto_addr, auto_bind_ip,
3519 auto_bind_port and auto_public_ip.
3521 * Changed the interface for silc_client_send_key_agreement
3522 in lib/silcclient/silcapi.h
3526 irssi/src/silc/core/silc-core.c
3528 lib/silcclient/silcapi.h
3529 irssi/src/silc/core/silc-channels.c
3530 lib/silcclient/client_keyagr.c
3533 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3535 * Added silc_pkcs_public_key_compare to compare two
3536 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3538 * Check that the client who set the founder mode on the
3539 channel is the same client that is giving the founder
3540 mode to itself. It is done by comparing the saved public
3541 key (it is saved even in the authentication is passphrase).
3542 Affected file silcd/command.c.
3544 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Do not process packet for disconnected socket connection.
3547 Affected file lib/silccore/silcpacket.c.
3549 * Process the DISCONNECT packet through scheduler in the
3550 client library. Affected file lib/silcclient/client.c.
3552 * Fixed the silc_client_packet_parse to not to increase
3553 the packet sequence number if the conn->sock and the
3554 current socket connection is not same. This can happen
3555 for example during key agreement when the conn includes
3556 multiple socket connections (listeners). Affected file
3557 lib/silcclient/client.c.
3559 * The sender of the file transfer request now provides also
3560 the pointer (listener) for the key exchange protocol. If
3561 the listener cannot be created then it sends empty key
3562 agreement and lets the receiver provide the listener.
3564 Added `local_ip' and `local_port' arguments to the
3565 silc_client_file_send. If they are provided they are used,
3566 if not then it will attempt to find local IP address, if
3567 not found or bind fails then the remote client will provide
3570 Affected files are lib/silcclient/client_ftp.c and
3571 lib/silcclient/silcapi.h.
3573 * Extended the FILE SEND command to support defining the
3574 local IP and port for key exchange listener. They are
3575 optional. Affected file irssi/src/silc/core/silc-servers.c.
3577 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Defined to WHOIS command reply the sending of fingerprint
3580 of the client's public key (if the proof of posession of the
3581 corresponding private key is verified by the server).
3582 Updated to the protocol specification.
3584 * Added support of receiving the client's public key's
3585 fingerprint in command reply in client library. Affected
3586 file is lib/silcclient/command_reply.c, and
3587 lib/silcclient/idlist.[ch].
3589 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3591 * Do not send over 128 chars long nickname to the server
3592 in NICK command. Affected file lib/silcclient/command.c.
3594 * Do not send over 256 chars long channel names to the server
3595 in JOIN command. Affected file lib/silcclient/command.c.
3597 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3599 * Assure that silc_server_close_connection cannot be called
3600 twice for same socket context. Affected file is
3603 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Send error message to application if opening file for
3606 writing during file transfer fails. Affected file is
3607 lib/silcclient/client_ftp.c.
3609 Remove all file transfer sessions for a client that we're
3610 removing from ID cache.
3612 Affected file is lib/silcclient/client_ftp.c.
3614 * Fixed silc_net_addr2bin to return correct address. Affected
3615 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3617 * Fixed file transfer session removing on signoff notify.
3618 Affected file irssi/src/silc/core/silc-servers.c.
3620 * Added the SilcClientFileError to be returned in the monitor
3621 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3622 Affected file lib/silcclient/silcapi.h.
3624 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Fixed a crash in silc_client_ftp_free_sessions and
3627 silc_client_ftp_session_free_client. Affected file
3628 lib/silcclient/client_ftp.c.
3630 * Added `disabled' field in the SilcChannelEntry in the server
3631 to indicate if the server entry is disabled. Affected file
3632 silcd/idlist.h, silcd/command[_reply].c.
3634 * SILC server adds now /var/run/silcd.pid everytime it is
3635 started. Affected file silcd/silcd.c.
3637 * Added silc_server_packet_send_clients to send a packet to
3638 the provided table of client entries. Affected file
3639 silcd/packet_send.[ch].
3641 * Fixed a crash in client resolving in client_prvmsg.c in
3642 client library. Affected file lib/silcclient/client_prvmsg.c.
3644 * Do not actually remove the client directly from ID cache
3645 during SERVER_SIGNOFF, but invalidate it. This way we
3646 preserve the WHOWAS info for the client. Affected file
3647 silcd/server_util.c.
3649 * Fixed SERVER_SIGNOFF notify handling in the server. The
3650 server is now able to process incoming SERVER_SIGNOFF notify
3651 for a server that it doesn't even know about. It will remove
3652 the clients provided in the notify. Affected file
3653 silcd/packet_receive.c.
3655 * Check for partial packet in data queue after every packet that
3656 was found from the queue. Return and wait for more data if
3657 there is partial data in queue. Affected file is
3658 lib/silccore/silcpacket.c.
3660 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3662 * Added SilcClietFileError enum to indicate error in

3675 irssi/src/fe-common/silc/module-formats.[ch].
3677 * Wrote a help file for FILE command.
3679 * Added silc_rng_global_get_byte_fast to get not-so-secure
3680 random data as fast as possible. Random data is read from
3681 /dev/urandom if available and from the SILC RNG if not
3682 available. It is used in padding generation. Affected file
3683 lib/silccrypt/silcrng.[ch].
3685 * All packets in client library are now processed synchronously.

3698 * Assure that silc_client_notify_by_server_resolve does not
3699 resolve the client information multiple times. If it cannot
3700 be found by the first it cannot be found at all. Affected
3701 file lib/silcclient/client_notify.c.
3703 * Fixed WHOWAS command reply calling. Affected file
3704 lib/silcclient/command_reply.c.
3706 * Removed all references to silc_idlist_get_client from the
3707 Irssi SILC client since that call is internal call used by
3708 the library. The Irssi SILC client will use now client
3709 retrieval functions found in silcapi.h.
3711 * Fixed a bug in resolving nickname info before sending
3712 private message. It used freed memory. Affected file
3713 irssi/src/silc/core/silc-servers.c.

3734 * Added silc_net_localip to return local host's IP address.
3735 Affected file lib/silcutil/silcnet.[ch].
3737 * If key exchange or rekey protocol is active for a connection
3738 parse all packets syncronously since there might be packets
3739 in packet queue that we are not able to process without first
3740 processing packets before them. Affected file silcd/server,
3741 lib/silcclient/client.c.
3743 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3744 whether library should continue processing the packet.
3745 Affected file lib/silccore/silcpacket.h.

3791 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3792 is incomplete and is being resolved, it won't be resolved
3795 Make sure also that USERS command reply does not resolve
3796 twice information. Affected file is
3797 lib/silcclient/command_reply.c.
3799 Make sure that silc_client_get_clients_by_list does not
3800 resolve twice same information.
3802 * Check for valid client->id in the silc_server_free_client_data.
3803 Affected file silcd/server.c.
3805 * Fixed /GETKEY nick@server not to crash if the server entry
3806 is not found. Affected file lib/silcclient/command.c.
3808 * Fixed the silc_server_check_cmode_rights to check the
3809 requested modes correctly. Affected file silcd/command.c.

3814 Affected file silcd/command.c.
3816 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Call the silc_server_udpate_servers_by_server in the
3819 primary router that comes back online in the backup resuming
3820 protocol. Otherwise it routes packets wrong. Affected file
3821 silcd/server_util.[ch], silcd/server_backup.c.
3823 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3825 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3826 lib/silcutil/silcbuffmt.[ch].
3828 * Redefined the SILC packet header to include the padding
3829 length. Affected file lib/silccore/silcpacket.[ch].
3831 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3832 length for maximum padding up to 128 bytes). Affected
3833 file lib/silccore/silcpacket.h.
3835 * Removed all backwards support for old 0.5.x MAC thingies.
3836 The SILC packet header change makes it impossible to be
3837 backwards compatible.
3839 * Send the ENDING packet with timeout in the backup resuming
3840 protocol. This is to assure that all routers has connected
3841 to the primary router. Affected file silcd/server_backup.c.
3843 * Changed the RNG to take the first IV from random data. It
3844 used to take it from zero actually. Changed the RNG also
3845 to use /dev/urandom during session. /dev/random is used
3846 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3848 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Changed the SILC packet header to have the first two bytes
3851 (the packet length) encrypted. Affected files aroung the
3852 code tree, lib/silccore/silcpacket.[ch]. Removed the
3853 SilcPacketCheckDecrypt callback. It is not needed anymore
3854 since the silc_packet_receive_process will determine now
3855 whether the packet is normal or special.
3857 * Implemented the unidirectional MAC keys. Affected files
3858 lib/silcske/silcske.c, silcd/protocol.c and
3859 lib/silcclient/protocol.c.
3861 * Implemented the packet sequence number to the MAC computation.
3862 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3863 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3864 lib/silcclient/protocol.c.
3866 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Allow backup router to announce servers. All servers
3869 announced by backup router are added to the global list
3870 automatically. Update hte server's socket to our primary
3871 router also when backup router announces a server.
3872 Affected file silcd/packet_receive.c.
3874 * Do not update the client->router in the function
3875 silc_server_udpate_clients_by_server if the client is on
3876 global list. We might fail to find any specific server
3877 for locally connected clients and local cell clients. They
3878 should still use the `from' and not `to' as client->router.
3879 This fixes backup router resuming protocol. Affected file
3880 silcd/server_util.c.
3882 * Decrease channel statistics count only if the channel
3883 deletion worked. Affected files are silcd/server.c and
3884 silcd/server_util.c.
3886 * Added silc_server_update_servers_by_server to update origin
3887 of all server entries. Used during backup router protocol.
3888 Affected files silcd/server_util.[ch], silcd/server.c. and
3889 silcd/backup_router.c.
3891 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3892 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3893 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3894 lib/silccrypt/silchmac.c.
3896 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3898 * Assure that router cannot reroute the same channel message
3899 to the sender. Affected file silcd/packet_receive.c.
3901 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3903 * Made better checks that the channel message is not sent
3904 to the router it came from. Affected file is
3905 silcd/packet_send.c. Fixed memory leak too.
3907 * Announce informations for incoming router connection, but
3908 only after checking if it is replaced by backup router.
3909 Affected file silcd/packet_receive.c.
3911 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Fixed the backup resuming protocol to work in multiple
3914 router environment. Affected file silcd/server_backup.c.
3916 * Route packet only to one router in the function
3917 silc_server_packet_send_to_channel. Affected file is
3918 silcd/packet_send.c.
3920 * Fixed silc_server_send_notify_dest to set the broadcast
3921 flag. Fixed the silc_server_send_notify_topic to actually
3922 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3923 Affected file silcd/packet_send.c.
3925 * Changed the SFTP Filesystem interface. Changed the
3926 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3927 the filesystem operation function. The SilcSFTPFilesystem
3928 is now a context that is allocated by all filesystem allocation
3929 functions and it already includes the operations structure
3930 and filesystem specific context. It is given as argument
3931 now to the silc_sftp_server_start. This made the interface
3932 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3933 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3935 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3937 * Changed the backup router adding and getting interfaces
3938 in the server. The router that will be replaced by the
3939 specified backup router is now sent as argument. Affected
3940 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3943 * Added silc_net_addr2bin_ne to return the binary form of
3944 the IP address in network byte order. Affected files
3945 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3947 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3949 * Check for existing server ID in silc_server_new_server
3950 and in silc_server_connect_to_router_final and remove the
3951 old entry if it exists. Affected file silcd/packet_receive.c,
3954 * Send the channel message always to only one router, either
3955 in upstream or downstream. Affected file is
3956 silcd/packet_send.c.
3958 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3960 * Wrote the definition of the backup resuming protocol to the
3961 protocol specification.
3963 * Removed one redundant channel key generation from normal
3964 server during joining procedure. Removed one redundant
3965 channel key sending from server to router during joining
3966 procedure. Affected file silcd/command.c.
3968 * Made minor bugfixes to the backup router resuming protocol.
3969 Affected file silcd/server_backup.c, server.c.

3974 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3977 * Implemented the backup resuming protocol that is used to
3978 resume the primary router position in the cell after the
3979 primary router comes back online. Affected files
3980 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3981 and silcd/server_util.[ch].
3983 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3985 * Sleep two (2) seconds after sending QUIT command to server.
3986 Affected file lib/silcclient/command.c.
3988 * Assure that if outgoing data buffer is pending do not force
3989 send any data. Affected file silcd/packet_send.c.
3991 * Assure that if outgoing data buffer is pending do not force
3992 send any data. Affected file lib/silcclient/client.c.
3994 * Implemented the backup router support when the primary router
3995 goes down. The servers and routers can now use the backup
3996 router as new primary router without loosing connectivity.
3998 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4001 in the server to indicate disabled entry. All data read
4002 from the connection will be ignored and no data is sent
4003 for entry that is disabled. Affected files are
4004 silcd/idlist.h, silcd/server.c.
4006 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4008 * Created SFTP client and server test programs in the
4009 lib/silcsftp/tests directory.
4011 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * Implemented memory filesystem (virtual filesystem) for
4014 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4017 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * Implemented the SFTP (SSH File Transfer Protocol) to the
4020 lib/silcsftp. It includes SFTP client and SFTP server
4023 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4025 * Moved lib/silccore/silcprotocol.[ch] to the
4026 lib/silcutil library.
4028 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4029 take variable argument list pointer as argument. Affected
4030 file lib/silcutil/silcbuffmt.[ch].
4032 * Added silc_buffer_set function that is used to set data
4033 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4034 Affected file lib/silcutil/silcbuffer.h.
4036 * Changed various routines in the core library to use the new
4037 silc_buffer_set instead of allocating new buffer only for
4040 * Added 64-bit value formatting and unformatting support to the
4041 silc_buffer_[un]format routines. Affected file is
4042 lib/silcutil/silcbuffmt.[ch].
4044 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4045 to includes/bitmove.h.
4047 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4049 * Fixed channel user mode saving in client library. Affected
4050 file lib/silcclient/command[_reply].c.
4052 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4054 * Defined the file transfer to the SILC Protocol. Added
4055 new packet type SILC_PACKET_FTP and defined File Transfer
4056 Payload. The mandatory file transfer protocol is SFTP
4057 (SSH File Transfer Protocol). Affected file in addition
4058 of the internet draft is lib/silccore/silcpacket.h.
4060 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4061 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4062 is used as part of backup router protocol when the primary
4063 router of the cell is back online and wishes to resume
4064 the position as primary router.
4066 * Redefined the MAC generation keys in the protocol. The
4067 same key is not used anymore in both direction. Both
4068 direction will now use different keys for sending and
4069 receiving. This fixes a potential security flaw. This
4070 change causes incompatibilities in the protocol.
4072 * Redefined also the MAC computation from the packet.
4073 An packet sequence number is now added to the MAC
4074 computation. This prevents possible replay attacks against
4075 the protocol. This change too causes incompatibilities
4078 Added `sequence' field to the SilcPacketContext to hold
4079 the current sequence number for the packet.
4081 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4083 * Added `created' field to the SilcIDListData in the file
4084 silcd/idlist.h to indicate the time when the entry was
4087 * Added `created' field to the SilcChannelEntry too. Affected
4088 file silcd/idlist.h.
4090 * Added `creation_time' aguments to all the announcement functions
4091 in the server. If it is provided then only the entries that
4092 was created after the provided time frame are actually
4093 announced. Affected file silcd/server.[ch].
4095 * The protocol says that the Channel ID's IP address must be
4096 based on the router's IP address. Added check for this in
4097 the silc_server_new_channel when processing incoming New Channel
4098 Payload. Affected file silcd/packet_receive.c.
4100 * Print out the correct version with --version in SILC client.
4101 Affected file irssi/src/silc/core/silc-core.c.
4103 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4105 * Fixed WHOWAS command to check for completnes of the client
4106 entry always, not just when the command is coming from client.
4107 Affected file silcd/command.c.
4109 * Added new function silc_server_packet_queue_purge to purge the
4110 outgoing data queue to the network. After the function returns
4111 it is guaranteed that the outgoing packet queue is empty.
4112 Affected file silcd/packet_send.[ch].
4114 * Purge the outgoing packet queue in the rekey protocol's final
4115 callback to assure that all rekey packets go to the network
4116 before quitting the protocol. Affected file silcd/server.c.
4118 * Added silc_client_packet_queue_parse as similar function as
4119 in server to the client library. The affected file is
4120 lib/silcclient/client.c.
4122 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4124 * Splitted silcd/server.c and created silcd/server_util.[ch]
4125 for utility functions.
4127 * Added new socket flag SILC_SF_DISABLED to indicate that the
4128 connection is open but nothing can be sent to or received from
4129 the connection. Affected file lib/silcutil/silsockconn.[ch].
4130 The checking for disabled socket is checked in the low level
4131 silc_socket_write and silc_socket_read functions.
4133 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4135 * Allow only nicknames and channel names that fits into the
4136 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4138 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4140 * When processing JOIN command reply in server check that if
4141 the channel exists in our global list we'll move it the local
4142 list. Affected file silcd/command_reply.c.
4144 * Fixed the check whether client is joined on the channel already
4145 in JOIN command. Affected file lib/silcclient/command.c.
4147 * Fixed the JOIN command reply to check whether the channel
4148 already exists. Affected file lib/silcclient/command_reply.c.
4150 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4152 * Added silc_ske_status_string to map the SKE error numbers
4153 to readable strings. The affected files are
4154 lib/silcske/silcske[_status].[ch].
4156 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4158 * Do not show the private channels on the WHOIS channel list
4159 as it is not allowed by the protocol. The affected file is
4162 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4164 * Assure that the packet length digged from the actual packet
4165 is something sensible in the silc_packet_decrypt_rest_special
4166 in lib/silccrypt/silcpacket.c.
4168 * Free and NULL the allocated pointer in silc_hmac_alloc if
4169 the HMAC allocation fails. The affected file is
4170 lib/silccrypt/silchmac.c.
4172 * Print the selected security properties to the log files in
4173 the server. Affected file silcd/protocol.c.
4175 * Add SKE's reference counter even if calling the completion
4176 callback manually. Otherwise it goes negative, although it
4177 does not cause any problems. The affected file is
4178 lib/silcske/silcske.c.
4180 * Remove the client entry with short timeout after giving the
4181 KILL command. Affected file lib/silcclient/command.c.
4183 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4184 case all found clients are already disconnected (WHOWAS would
4185 found them) in the server. Affected file silcd/command.c.
4187 * Update the last_receive (time of last data received) to be
4188 updated only when received private or channel message so that
4189 the idle time showed in WHOIS makes more sense.
4191 * Added boolean field `valid' in to the SilcClientEntry in the
4192 client library to indicate whether the entry is valid or not.
4193 This fixes the nickname change bug on channel when changing
4194 the nickname to be same than the old (like nick to Nick) the
4195 nickname formatter doesn't set the new nick anymore to Nick@host.
4196 Affected file lib/silcclient/idlist.[ch].
4198 * Now actually fixed the nickname changing on disconnection.
4199 Added new function silc_change_nick to the Irssi SILC Client.
4200 Affected file irssi/src/silc/core/client_ops.c,
4201 irssi/src/silc/core/silc-nicklist.[ch].
4203 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Check that the public key exists in the GETKEY command before
4206 trying to encode it. Affected file silcd/command.c.
4208 * Print some notifications on received public keys with GETKEY
4209 command in the Irssi SILC Client. Affected files are
4210 irssi/src/fe-common/silc/module-formats.[ch],
4211 irssi/src/silc/core/client_ops.c.
4213 * Use IDENTIFY command to resolve the server information in the
4214 GETKEY command instead of INFO command. Affected file
4215 lib/silcclient/command.c.
4217 * All command reply functions in the client library now calls
4218 the pending command reply callbacks even if an error has
4219 occurred. The server has done this a long time and now it was
4220 time to move the client library to this as well. Now all
4221 errors can be delivered back to the pending command reply
4222 callbacks if necessary. Affected files are
4223 lib/silcclient/command[_reply].[ch].
4225 * Change the nickname on disconnection back to the username
4226 because in reconnect the server will enforce it to it anyway.
4227 Affected file irssi/src/silc/core/silc-servers.c.
4229 * Fixed a config file parsing bug in the Irssi SILC client.
4230 Affected file irssi/src/silc/core/clientconfig.c.
4232 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4234 * When printing the channel mode on JOIN, verify that the
4235 channel key and channel's HMAC are valid. Affected file
4236 irssi/src/silc/core/client_ops.c.
4238 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4241 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4242 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4244 * Removed channel key rekey task deleting from the function
4245 silc_server_save_channel_key. Affected file silcd/server.c.
4246 Added explicit timeout task context instead that is used to
4247 delete the task if we are registering a new task before the
4248 new task has elapsed.
4250 * When channel key rekey occurs the client library now saves
4251 the old channel key for a short period of time (10 seconds) and
4252 is able to use it in case some is still sending channel
4253 messages encrypted with the old key after the rekey. Affected
4254 file lib/silcclient/[idlist.h|client_channel.c].
4256 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4258 * Added check to the silc_server_new_id_real to not accept
4259 new ID if it is the sender's own ID. Affected file is
4260 silcd/packet_receive.c.
4262 * Assure that we do not announce ourself or the one we've
4263 sending our announcements when we're router and are announcing
4264 servers to our primary router. Affected file silcd/server.c.
4266 * Fixed silc_server_command_identify_check_client to assemble
4267 correct WHOIS packet. It send corrupted WHOIS packet and
4268 caused problem with router to router connections. Affected
4269 file silcd/command.c.
4271 Fixed also silc_server_command_whois_check the same way
4272 as for the IDENTIFY command.
4274 * Added new SilcIDListStatus to the server in the SilcIDListData
4275 structure. The status now includes the current status of
4276 the entry (like registered, resolved etc.). Affected file
4277 silcd/idlist.[ch]. Defined a bunch of different status types
4278 as well. This replaced the old boolean registered field as well.
4280 Added resolve_cmd_ident field to the SilcClientEntry structure
4281 too so that if the entry is for example being resolved so
4282 another command may attach to the same pending command reply
4283 without requiring to resolve the same entry again. This concept
4284 should optimize the WHOIS and the IDENTIFY resolving under
4285 heavy load by taking away unnecessary resolving for entries
4286 that are being resolved already.
4288 Added support for adding multiple pending commands for one
4289 command idenfier. Affected file silcd/command[_reply].[ch].
4291 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4292 before deleting the data. Otherwise the hash table will have
4293 freed data in comparison functions. Affected file is
4294 silcd/command_reply.c.
4296 * Fixed silc_idlist_replace_client_id to add the new entry to
4297 the cache with NULL nickname. Otherwise there will be invalid
4298 memory as the nickname after the nickname is freed. Affected
4299 file silcd/packet_receive.c.
4301 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4302 saved into wrong slots because the previous number of entries
4303 was not taken into account. Affected file silcd/idlist.c.
4304 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4306 * If we are router and we receive JOIN notify to a channel that
4307 does not have any users then notified client is marked as the
4308 channel founder, as it is it. The affected file is
4309 silcd/packet_receive.c
4311 * Added to the extended hash table API's table_del_*ext functions
4312 the destructor as argument too, so that the caller can decide
4313 which destructor to use or whether to use destructor at all.
4314 Affected file lib/silcutil/silchashtable.[ch].
4316 * Fixed ID Cache purging. It actually deleted the entries from
4317 the hash table after the data was freed. The hash table ended
4318 up comparing freed memory. The affected file is
4319 lib/silccore/silcidcache.c.
4321 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4323 * Fixed Irssi SILC client's KILL command's HELP syntax.
4325 * The USERS command now resolves the detailed user information
4326 if the userinfo field is missing. Affected file is
4327 lib/silcclient/command_reply.c.
4329 * Do not print error in silc_file_read if the read file does
4330 not exist. Just silently return NULL. Affected file is
4331 lib/silcutil/silcutil.c.
4333 * Fixed the silc_log_output to not wine about NULL filename
4334 and to not create some bogus " " filename. Affected file is
4335 lib/silcutil/silclog.c.
4337 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Fixed various printing bugs on the user interface in the
4340 Irssi SILC Client. Minor changes that were forgotten from
4343 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4345 * Fixed the configure.in.pre and the compilation and distribution
4346 environment to support the new autoconf 2.52. That version is
4347 now required to compile the CVS trunk.
4349 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4351 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4352 to generally parse user@fqdn format strings. Affected file
4353 lib/silcutil/silcutil.c.
4355 * Added nickname_format and nickname_force_format fields to the
4356 SilcClientParams structure. The first one defines the format
4357 for the nicknames that the library will enforce if the receives
4358 multiple same nicknames. The second one is boolean value and
4359 can be used to force the library to always enforce the format
4360 to the nicknames regardles whether there are multiple nicknames
4361 or not. This configurable formatting was employed to flexibly
4362 support accessing multiple nicknames from the user interface.
4363 The userinterface can now set the nicknames to what ever format
4364 they prefer. Affected file lib/silcclient/silcapi.h.
4366 Added function silc_client_nickname_format to the file
4367 lib/silcclient/idlist.c. It performs the nickname formatting.
4369 Added new field `hostname´ to the SilcClientEntry context.
4370 It holds the hostname of the client. Affected file is
4371 lib/silcclient/idlist.h.
4373 * Irssi SILC Client sets the nicknames in nick@hostn format.
4374 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4375 irssi/src/silc/core/silc-core.c.
4377 The WHOIS printing now also shows both the real nickname and
4378 the formatted nickname so that user knows how to access the
4379 user if there are multiple same nicknames cached. Affected
4380 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4381 printing formatting too to take the hostname now as a separate
4382 argument. The Affected file is
4383 irssi/src/fe-common/silc/modules-formats.[ch].
4385 * Changed the silc_client_get_clients_local to accept the formatted
4386 nickname as argument. It accepts the real nickname too but the
4387 formatted nickname can be used to find the true entry from
4388 multiple entries. Affected file lib/silcclient/silcapi.h and
4389 lib/silcclient/idlist.c.
4391 * Added nickname_format_parse field to the SilcClientParams.
4392 It is a callback function provided by the application to parse
4393 the nickname out of the formatted nickname string. The library
4394 calls it to get the nickname from the formatted string. Since
4395 the application generally knows better the format of the nickname
4396 string it parses it instead of the library, even though library
4397 encodes the formatted string. If the callback function is not
4398 provided then the library will use the string as is. The
4399 affected file is lib/silcclient/silcapi.h.
4401 * All the nickname strings passed to the client library in
4402 commands are now expected to be formatted nickname strings.
4403 If the command does not support the formatted nickname string
4404 it will assume that the sent string is the actual nickname.
4405 Affected file lib/silcclient/command.c.
4407 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4409 * Added public key authentication support to OPER and SILCOPER
4410 commands in the client library. Affected file is
4411 lib/silcclient/command.c.
4413 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4415 * Changed the get_auth_methdod client operation to be asynchronous.
4416 It can be async if the application resolves the authentication
4417 method from the server during the negotiation. Added new
4418 SilcGetAuthMeth completion callback that the application will
4419 call after resolving the authentication method.
4421 Added function silc_client_request_authentication_method that
4422 the application can use to resolve the authentication method
4423 from the server. Added also SilcConnectionAuthRequest callback
4424 that the library will call after the server has replied. The
4425 application can call this function if it does not know the
4426 current authentication method.
4428 Affected files are lib/silcclient/client.c and
4429 lib/silcclient/silcapi.h.
4431 * The Irssi SILC client now automatically resolves the authentication
4432 method incase any configuration information is not present (and
4433 currently there never is). The affected file is
4434 irssi/src/silc/core/client_ops.c.
4436 * Fixed public key authentication from the client library.
4437 Affected file lib/silcclient/protocol.c. Changed also the
4438 protocol specification about the public key authentication in
4439 the connection authentication protocol. The actual data to be
4440 signed is now computed with a hash function before signing.
4442 * Fixed the public key authentication from the server as well.
4443 Affected file silcd/protocol.c.
4445 * Removed the mlock()'s from the memory allocation routines.
4446 Affected file lib/silcutil/silcmemory.c. The ./configure does
4447 not check anymore for the mlock(). Affected file is
4450 * Fixed USERS command in server to allow the execution of the
4451 command for private and secret channels if the client sending
4452 the command is on the channel. Affected file silcd/command.c.
4454 * Fixed silc_client_get_clients_local to return the clients
4455 count correctly. It could return wrong value. Affected file
4456 lib/silcclient/idlist.c.
4458 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4460 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4461 types. The assembler optimizations seemed not to like 64-bit
4462 data types. The assmebler optimizations thus are now enabled
4463 also for BSD systems as opposed to only enable them for Linux.
4465 * Do not check for threads at all on BSD systems. Affected
4466 file configure.in.pre.
4468 * Removed -n and -h options from the Irssi SILC Client since
4469 they are not used in silc.
4471 * Fixed the prime generation to assure that the first digit
4472 of the generated random number is not zero since our conversion
4473 routines does not like number strings that starts with zero
4474 digit. If zero digit is seen the random number is regenerated.
4475 This caused some corrupted RSA keys when the zero first digit
4476 was met. Affected file lib/silcmath/silcprimegen.c.
4478 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4480 * Fixed WIN32 configuration in the ./configure script.
4481 Fixed to include xti.h on environments that has it.
4482 Patches by Carsten Ilchmann and andrew.
4484 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4486 * Changed the silc_id_create_client_id to be collision
4487 resistant. It is now assured that there cannot be created
4488 two same client ID's. I suspect that some weird bugs in
4489 the server were actually caused by duplicate Client IDs.
4490 Affected file silcd/serverid.[ch]. A router receiving
4491 new ID now also assures and informs the sending server
4492 if the ID caused collision.
4494 * Changed the silc_id_create_channel_id to also assure that
4495 there are no collisions.
4497 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4499 * Statement about ignoring the Mutual Authentication flag when
4500 performing rekey with PFS was a bit misleading. It is ignored
4501 if it was set in the initial negotiation, it cannot be even
4502 set in the rekey. Fixed in the ke-auth draft. Started the
4503 new versions of the protocol drafts in the doc/.
4505 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4507 * Fixed a bug in silc_client_command_identify_save when saving
4508 new channel information. The channel name was no duplicated
4509 and caused crash on exit. Affected file is
4510 lib/silcclient/command_reply.c.
4512 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4514 * Fixed the getkey command handling in the server. Send just
4515 empty OK reply to the sender if the key could not be fetched
4516 (but everything else was ok, like the key just was not available).
4517 Changed the public key parameter to optional in the protocol
4518 specs so that empty OK reply can be sent. Affected file
4521 Added a message to Irssi SILC client to tell to user if the
4522 server did not return a public key.
4524 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4526 * Fixed a channel key regeneration bug. It registered new
4527 timeout tasks exponentially until all system resources were
4528 used. Affected file silcd/server.c.
4530 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4532 * Added the SILC Document generator to the scripts/silcdoc.
4533 It can be used to generate the Toolkit Reference Manual out
4534 of the source tree. Internally it will also use the RoboDoc
4535 generator now imported in util/robodoc.
4537 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Added couple of return's in rekey protocol if error orccurred
4540 during the protocol. The execution must be terminated.
4541 Affected file silcd/protocol.c. Also, terminate the protocol
4542 always with timeout.
4544 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4546 * The client's Client ID was created initally from the wrong
4547 nickname (it could have been in format nick@host) in the
4548 silc_server_new_client. Affected file silcd/packet_receive.c
4550 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4552 * Added some SILC_LOG_ERROR's to various error conditions
4553 if client could not be added to ID cache. Affected files
4554 silcd/packet_receive.c and silcd/server.c.
4556 * When client's sock->user_data is freed, NULL also the
4557 client->router and client->connection pointers. Added check
4558 for these pointers being NULL to various places around the
4559 code. Affected file silcd/server.c.
4561 * Added client->data.registered == TRUE checks to various
4562 places around the code to assure that unregistered client's
4563 are not handled when it is not allowed. Affected file
4566 * Added `bool registered' fields to all
4567 silc_idlist_[server|client]_get_* routines to indicate whether
4568 the fetched client needs to be registered or not. Affected
4569 file silcd/idlist.[ch].
4571 * Add your own entry as registered to the ID cache in the
4572 server. Affected file server.c.
4574 * Fixed a bug in silc_server_new_server. The SilcServer was
4575 set as the new server's context instead of SilcServerEntry.
4576 This naturally caused some weird bugs.
4578 * Added "updated" field the SilcChannelEntry which indicates
4579 the time since the channel entry was last accessed. This
4580 can be used to determine whether it is necessary to
4581 announce the channel after backup resuming protocol.
4582 Affected files silcd/idlist.[ch].
4584 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4586 * Do not delete the channel rekey task when adding it
4587 for in silc_server_create_channel_key.
4589 * Changed the silc_server_create_channel_key to return
4590 TRUE or FALSE to indicate the success of the channel key
4593 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4595 * Fixed MSVC++ project files and added missing files to
4596 Makefiles under win32/.
4598 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4600 * Do not add TCP_NODELAY flag if the operating system
4601 does not have it defined. Affected files are
4602 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4604 * Fixed buffer overflow from Irssi SILC Client. Affected
4605 file irssi/src/fe-common/core/themes.c.
4607 * Fixed double free in client library in the file
4608 lib/silcclient/client.c when disconnecting from server.
4610 * Applied double free patch from cras to Irssi SILC client.
4611 Affected files irssi/src/core/[modules/expandos].c
4613 * Fixed the disconnection handling to Irssi SILC Client.
4614 The application must call silc_client_close_connection
4615 in ops->connect client operation in case of failure of
4616 the connection. Affected file is
4617 irssi/src/silc/core/client_ops.c.
4619 * Do not set sock->protocol to NULL in the function
4620 silc_client_close_connection after executing the protocol's
4621 final callback since the sock might not be valid anymore.
4622 Affected file lib/silcclient/client.c.
4624 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4626 * Do not enable SILC_THREADS if the linking with libpthread
4627 did not happen. Affected file configure.in.pre.
4629 * Added notion to protocol specification that server must
4630 verify the sent authentication payload with CMODE when
4631 setting the channel founder key. Implemented it to the
4632 server. Affected file silcd/command.c.
4634 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4636 * Added _EXTRA_DIST SILC distribution variable to the
4637 distributions file. It is used to conditionally add extra
4638 files or directories to the specific distribution. Affected
4639 files ./prepare, Makefile.am.pre and distributions.
4641 Removed the `_' from the start of the distribution names.
4644 * Added README.WIN32 for instructions to compile the Toolkit
4647 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4649 * Fixed a double free in disconnection in the server. Affected
4650 file is silcd/server.c.
4652 * Fixed the lib/silcske/groups.c to work now also with GMP
4653 MP library. The string conversion did not work when using
4654 specific base and the base is indicated in the string as well.
4656 * Created win32/ directory which now includes MSVC++ specific
4657 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4658 It will appear only in the toolkit distribution
4660 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4662 * Changed the key material distribution function in case when
4663 the hash output is too short. The data is now concatenated
4664 a bit differently than it used to. Made the change to the
4665 SKE protocol specification.
4667 * Added better GMP detection to configure.in.pre. A patch
4670 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4672 * Fixed a minor bug in SKE that might cause some problem on
4673 some platforms. Affected file lib/silcske/silcske.c.
4675 * Added the cookie checking for initiator in the SKE. It checks
4676 that the responder returns the sent cookie unmodified. The
4677 affected file is lib/silcske/silcske.c. Added new SKE
4678 error type INVALID_COOKIE that can be sent during the
4679 negotiation. Fixed some memory leaks as well.
4681 * Added the "invalid cookie" error message to Irssi SILC client's
4684 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4686 * Added `task_max' field to the SilcClientParams to indicate
4687 the maximum tasks the scheduler can handle. If set to zero,
4688 default values are used. Affected file lib/silcclient/silcapi.h.
4690 * Fixed memory leaks in silc_client_close_connection. Affected
4691 file lib/silcclient/client.c.
4693 * Added silc_client_del_client_entry to client library to free
4694 all memory of given client entry. Affected file is
4695 lib/silcclient/idlist.[ch].
4697 * Added new functions silc_client_del_channel and
4698 silc_client_del_server to delete channel and server entries.
4699 Affected file lib/silcclient/[silcapi.h/idlist.c].
4701 * Removed silc_client_del_client_by_id from silcapi.h.
4703 * Fixed the INFO command to return the server's own info
4704 correctly when querying by Server ID. Affected file is
4707 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4709 * Removed the non-blocking settings in WIN32 code in the
4710 silc_sock_[read/write] and added SleepEx instead. Affected
4711 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4712 of input data is now checked with FIONREAD and ioctlsocket.
4714 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4716 * Call silc_schedule_task_del_by_context in the
4717 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4718 Affected file lib/silccore/silcprotocol.c.
4720 * Call silc_protocol_cancel for active protocols in the
4721 silc_server_close_connection if the funtion
4722 silc_server_free_sock_user_data has not been called.
4723 Affected file silcd/server.c.
4725 * Generic tasks cannot be deleted using the del_by_fd
4726 task deleting function since generic tasks does not match
4727 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4729 * Added a notion to SILCOPER help file that the SILCOPER works
4730 only on router server, not on normal server.
4732 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4734 * Added for WIN32 support for the new scheduler as well.
4735 Affected file lib/silcutil/win32/silcwin32schedule.c.
4737 * Fixed the SHA1 implementation to work on various platforms.
4739 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4741 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4742 API. It is part of the scheduler now. Everything else is
4743 as previously but some functions has changed their names.
4744 Checkout the lib/silcutil/silcschedule.h for the interface.
4745 Updated all applications to use the new interface. Affected
4746 files are lib/silcutil/silcschedule.[ch].
4748 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4750 * Found a bug in the SKE implementation. The HASH value,
4751 specified by the protocol, was not computed correctly. The
4752 public key of the responder was not added to the computation
4753 even though it is mandatory. Affected file lib/silcske/silcske.c.
4754 This unfortunately causes incompatibilities with older
4755 clients and servers.
4757 * Added WIN32 specific network init and uninit functions:
4758 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4759 the Winsock2. Affected file lib/silcutil/silcnet.h and
4760 lib/silcutil/win32/silcwin32net.c.
4762 * Set the socket always to nonblocking mode on WIN32 after
4763 reading data or writing data. Affected file is
4764 lib/silcutil/win32/silcwin32sockconn.c.
4766 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4768 * Fixed various compilation problems under WIN32. Affected
4769 files lib/silcutil/win32/silcwin32thread.c and
4770 lib/silcutil/win32/silcwin32schedule.c.
4772 * Removed all _internal.h #includes from public header
4773 files. Internal headers must never be included from
4776 Removed also the lib/silcske/payload_internal.h file.
4778 * All include files that may be needed (public and some others
4779 included by the public headers) by application developers are
4780 now copied to the ./includes directory. It does not copy any
4781 internal headers. Affected file Makefile.defines.pre and all
4782 Makefile.am's under lib/ and subdirs.
4784 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4786 * Do not change the ~/.silc directory's permissions automatically.
4787 Affected file irssi/src/silc/core/clientutil.c.
4789 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4791 * Do not cancel the protocol in silc_server_close_connection
4792 it might cause recursion. Now cancelled in the function
4793 silc_server_free_sock_user_data. Affected file silcd/server.c.
4795 * Fixed the silc_server_remove_clients_by_server to regenerate
4796 the channel keys correctly finally. Added also new function
4797 silc_server_remove_clients_channels to actually do it.
4798 Affected file silcd/server.c.
4800 * Fixed the silc_server_new_channel to not crash by giving
4801 wrong router to the new channel. Affected file is
4802 silcd/packet_receive.c.
4804 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4806 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4807 which is given as argument to the silc_client_alloc now.
4808 It can be used to configure the client and set various parameters
4809 that affect the function of the client.
4811 * The USERS command in server did not check whether the channel
4812 is private or secret. Affected file silcd/command.c.
4814 * Added new argument to the USERS command in protocol specification.
4815 The USERS command now can take the channel name as argument
4816 as well. Added support for this in client and server and
4817 updated the protocol specs.
4819 * Completed the GETKEY command in client. It can be now used
4820 to fetch also servers public key not only some clients.
4821 Affected files lib/silcclient/command[_reply].c.
4823 * Added silc_client_get_server to return server entry by the
4824 server name. Affected files lib/silcclient/silcapi.h and
4827 * Redefined the IDENTIFY command in protocol specification to be
4828 more generic. It now can be used to query information about
4829 any entity in the SILC Network, including clients, servers and
4830 channels. The query may be based either the entity's name
4831 or the ID. Added support for this in both client and server.
4833 Affected files silcd/command.c and lib/silcclient/command.c
4834 and command_reply.c.
4836 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4837 the _from_client and _from_server functions. Affected file
4840 * Added silc_client_get_channel_by_id_resolve to the file
4841 lib/silcclient/silcapi.h to resolve channel information by
4842 its ID. Added also silc_client_get_channel_by_id that
4843 does not resolve it from the server.
4845 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4847 * Added SilcServerEntry context into the client library
4848 to represent one server. The INFO command now allocates
4849 these to save the resolved server info. For now on the
4850 client library will also keep information about servers,
4851 connected and resolved with INFO.
4853 The INFO command now allocates the SilcServerEntry context
4854 and saves the server info there. The COMMAND_REPLY in
4855 the INFO now returns the parameters to application in
4856 same order as defined in the protocol specification.
4858 The entries are cached in the client->server_cache.
4860 * The INFO command is now issued after received the Client ID
4861 from the server. Affected file lib/silcclient/client.c.
4863 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4864 to the application as the mode changer might be server.
4865 It is guaranteed that NULL is not returned anymore to the
4866 application. Affected file lib/silcclient/client_notify.c.
4868 The ID Type is now also passed to the application so that
4869 it can check whether the returned entry is SilcClientEntry
4872 Added new function silc_client_get_server_by_id to return
4873 the server entry by ID. Affected files are the
4874 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4876 * Do not create the channel in the Irssi SILC Client when issuing
4877 the JOIN command but when received the sucessful JOIN command
4878 reply. Otherwise the channel might get created even though we
4879 could not join it. The Affected file is
4880 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4882 * Fixed a channel joining bug in router. The router must also
4883 check the channel modes, invite and ban lists etc. when serving
4884 the JOIN command sent by normal server. Affected file is
4885 silcd/command.c. The router now resolves the client's
4886 information from the server who sent the JOIN command if it
4887 does not know it, and processes the JOIN command only after
4890 * Changed the SilcCommandCb to take new argument; void *context2.
4891 Affected file lib/silccore/silccommand.h
4893 The second argument in the command callbacks in the server now
4894 includes the SilcServerCommandReplyContext if the command was
4895 called as pending command callback from the command reply.
4896 Otherwise it is NULL. When called as pending the status of the
4897 command reply will be checked and if it was erronous the
4898 error will be sent to the original sender of the command.
4899 This way the client always receives the error messages even
4900 though the server was actually the one who received the error
4901 when it resent the command to router, for example. Affected
4902 files silcd/command[_reply].[ch].
4904 * Fixed sending WHOWAS command's error message to client if
4905 the requested client could not be found. It was missing.
4908 * Changed the CMODE and CUMODE commands reply arguments in the
4909 protocol specification. The Channel ID is now sent in both
4910 of the commands to identify the channel. Implemented this
4911 new feature to the client and server. Affected files
4912 lib/silcclient/command_reply.c and silcd/command.c.
4914 * Made better checks for invite and ban lists in the JOIN
4915 command in server. Affected file silcd/command.c.
4917 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4919 * The server now performs the incoming host IP/DNS lookup
4920 using the silc_socket_host_lookup and thus does not block
4921 the server anymore. Affected file silcd/server.c.
4923 * Completed the multi-thread support for SILC Scheduler in
4924 the lib/silcutil/silcschedule.c.
4926 * Fixed the configure.in.pre to detect the pthread correctly
4929 * Fixed a deadlock in silc_task_queue_wakeup in the file
4930 lib/silcutil/silctask.c.
4932 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4934 * Added new function silc_schedule_wakeup that is used in
4935 multi-threaded environment to wakeup the main thread's
4936 schduler. It needs to be used when a thread adds a new task
4937 or removes a task from task queues. After waking up, the
4938 scheduler will detect the task queue changes. If threads
4939 support is not compiled in this function has no effect.
4940 Implemented the wakeup mechanism to both Unix and WIN32
4941 systems. Affected files are lib/silcutil/silcschedule.[ch],
4942 lib/silcutil/unix/silcunixschedule.c and the
4943 lib/silcutil/win32/silcwin32schedule.c.
4945 * Added new function silc_task_queue_wakeup to wakeup the
4946 scheduler by the specified task queue. Affected file
4947 lib/silcutil/silctask.[ch].
4949 * The silc_socket_host_lookup_start now wakes up the scheduler
4950 after adding the timeout task. Affected file is
4951 lib/silcutil/silcsockconn.c.
4953 * The silc_socket_host_lookup is synchronous now if the threads
4954 support is not compiled in. However, the callback is still
4955 called asyncronously through the scheduler, anyway. Affected
4956 file lib/silcutil/silcsockconn.c.
4958 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4960 * Added new function silc_socket_host_lookup to perform
4961 asynchronous IP and FQDN lookups for the socket connection.
4962 Affected files lib/silcutil/silcsockconn.[ch].
4964 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4966 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4967 that may or may not compile the mutex support in.
4969 Changed the silc_mutex_alloc interface. It allocates the
4970 mutex now to the sent pointer and returns TRUE or FALSE.
4972 Affected file lib/silcutil/silcmutex.h.
4974 * Wrote the SILC Task Queue interface to support multi-threads.
4975 Affected file lib/silcutil/silctask.[ch].
4977 * Wrote the SILC Scheduler to support multi-threads. Affected
4978 file lib/silcutil/silcschedule.c.
4980 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4982 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4983 in lib/silcutil/win32/.
4985 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4987 * Defined SILC Mutex API and SILC Thread API and implemented
4988 them for Unix. Affected files are
4989 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4990 lib/silcutil/unix/silcunixmutex.c and
4991 lib/silcutil/unix/silcunixthread.c.
4993 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4995 * Fixed the silc_server_remove_clients_by_server's channel
4996 key re-generation. The hash table handling was incorrect
4997 and would not work with many channels. Affected file is
5000 * Fixed some memory leaks around the server code.
5002 * Rewrote the silc_server_get_users_on_channel to support IPv6
5003 based Client ID's. Affected file silcd/server.c.
5005 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5006 specification. However, a separate document must be written
5007 to define the detailed signing procedure and the payload
5008 associated with the flag. Defined the flag to the
5009 lib/silccore/silcchannel.h as well.
5011 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5013 * Changed the dynamic tables to static size tables in the
5014 lib/silccrypt/silchmac.c.
5016 * Removed GCC dependencies from the code. A patch by cras.
5018 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5020 * Do not show the error "Error receiving packet bla bla"
5021 in server if it really was not an error (-2 means that reading
5022 is pending). Affected file silcd/server.c.
5024 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5026 * Fixed a possible crash in silc_server_remove_clients_by_server
5027 in silcd/server.c. Fixed there also some memory leaks.
5029 * Fixed the silc_idlist_replace_client_id. It could replace
5030 wrong key in the hash table. Affected file silcd/idlist.c.
5032 * Do not check whether there are global users on the channel
5033 if the channel->global_users is FALSE. Affected functions
5034 silc_server_remove_from_one_channel and
5035 silc_server_remove_from_channels in silcd/server.c. Also,
5036 do not check if the removed client is local as we can be
5037 sure that global client was not removed from the channel
5038 and checking for global users is not needed.
5040 * The silc_server_remove_clients_by_server now re-generates
5041 the channel keys correctly for those channels that had
5042 clients removed from them. Affected file silcd/server.c.
5044 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5046 * Found the reason of random crashes in the server. We weren't
5047 ignoring the SIGPIPE signal (which can be sent in write())
5048 and it crashed the server. Affected file silcd/silcd.c.
5050 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5052 * Assure that sock->user_data is not NULL in the function
5053 silc_server_packet_send in silcd/packet_send.c.
5055 * Disconnect the remote connection if it could not be added
5056 to any ID lists in the server. The affected file is
5059 * Check in silc_server_packet_send[_real/dest] that the
5060 socket is not disconnecting and ignore the data if it is.
5061 Affected file silcd/packet_send.c.
5063 * Define inline to __inline on native WIN32 compilation.
5064 Affected file includes/silcwin32.h.
5066 * Added some explicit type casts for inline code since MSVC
5067 require them. Affected files lib/silcutil/silcbuffer.h,
5068 lib/trq/silcdlist.h and lib/trq/silclist.h.
5070 * Print warning in log files from now on if the packet
5071 decryption fails. Affected file silcd/server.c.
5073 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5075 * Changed the `say' client operation's interface to accept
5076 new `type' argument to indicate the type of the message sent
5077 by the library. The application may filter the library's
5078 messages according the type. The affected file is the
5079 lib/silcclient/silcapi.h.
5081 * Added two new functions to lib/silcclient/silcapi.h:
5082 silc_client_del_client and silc_client_del_client_by_id.
5083 Affected file lib/silcclient/idlist.c.
5085 * Moved the clientincludes.h from includes/ to silc/ and
5086 serverincludes.h from includes/ to silcd/.
5088 * The modes for the CMODE and CUMODE are now passed as
5089 uint32 for application with COMMAND_REPLY. The affected
5090 file is lib/silcclient/command_reply.c.
5092 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5094 * /WHOIS without arguments shows client's own information.
5095 Affected file lib/silcclient/command.c.
5097 * Changed PING to not accept any arguments. The specs
5098 says that client can ping only the connected server so
5099 requiring an argument is not needed. Affected file is
5100 lib/silcclient/command.c.
5102 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5104 * Fixed a fatal bug in private message sending and reception
5105 encryption and decryption when using private message keys.
5106 The implementation was incorrect and did not follow the
5107 specification. It causd that some of the message were
5108 lost since it did not use the sending and receiving keys
5109 as the protocol suggests. This has been fixed and will cause
5110 incompatibilities with older clients when sending private
5111 message encrypted with private message keys. Affected files
5112 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5113 and various other in Irssi SILC Client.
5115 Added `responder' boolean argument to the functions
5116 silc_client_add_private_message_key[_ske] to indicate when
5117 the key is added as responder or initiator of the key
5120 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5122 * Removed the silc_ske_check_version function and created
5123 a SilcSKECheckVersion callback. Added also a function
5124 silc_ske_set_callbacks that is now used to set all SKE
5125 callbacks. The callback functions are not given to
5126 the SKE functions anymore, but this function is used to
5129 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5131 * Added `silc_version' argument to the silc_client_alloc
5132 to define the version of the application for the library.
5133 The library will use the version string to compare it
5134 against the remote host's (usually a server) version
5135 string. Affected file lib/silcclient/silcapi.h
5137 * Added the KE protocol context to Key Agreement context
5138 in client library so that we can abort the SKE if it
5139 is in process when we get timeout. Affected file is
5140 lib/silcclient/client_keyagr.c.
5142 * Do not resolve the client ID forever if it returns in the
5143 first time that such client does not exist. This was done
5144 for example with private message. Affected file is
5145 lib/silcclient/client_prvmsg.c.
5147 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5149 * Do not add regex.h for WIN32. The affected file
5150 includes/silcincludes.h.
5152 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5153 not work yet 100%. It generates the DLL's automatically
5154 when compiling with --with-win32 under cygwin.
5156 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5158 * lib/contrib/regex.c is not compiled on WIN32.
5160 * Added silc_net_get_socket_opt function to the
5161 lib/silcutil/silcnet.h.
5163 * Added includes/silcwin32.h for WIN32 specific includes
5166 * Do not use ptime structure or any of the posix process
5167 functions on WIN32 in lib/silccrypt/silrng.c.
5169 * Added silc_gettimeofday to provide generic function
5170 for struct timeval on all platforms. Added the function
5171 to lib/silcutil/silcutil.h.
5173 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5175 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5176 library as they clearly belong there. As a plus side we
5177 can make the actual socket connection routines platform
5180 Added also new generic function silc_socket_read and
5181 silc_socket_write (that used to be silc_packet_[read/write].
5182 The implementation of these are platform specific.
5184 * Added WIN32 specific routines of silc_socket_[read/write]
5185 to lib/silcutil/win32/silcwin32sockconn.c.
5187 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5189 * Added preliminary support for native WIN32 compilation under
5190 cygwin (using the -mno-cygwin option for GCC) to the
5191 ./configure.in.pre. The --with-win32 now prepares the
5192 compilation for native WIN32.
5194 * Rewrote the SILC Scheduler interface in the file
5195 lib/silcutil/silcschedule.h. The scheduler is now context
5196 based and does not have anymore any global static scheduler.
5197 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5198 and created lib/silcutil/win32 directory for WIN32 based
5201 * Added Unix specific network routines to the
5202 lib/silcutil/unix/silcunixnet.c and the old
5203 lib/silcutil/silcnet.c includes now only generic routines.
5205 Added WIN32 specific network routines to the
5206 lib/silcutil/win32/silcwin32net.c.
5208 * Added Unix specific utility functions from the
5209 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5211 * Added WIN32 SILC Scheduler to the file
5212 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5215 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5217 * Do not handle JOIN notify in the server if the target client
5218 is not registered (idata->registered == FALSE). The affected
5219 file is silcd/packet_receive.c.
5221 * Update the nickrec->founder in event_cumode in the Irssi SILC
5222 client. Affected file irssi/src/silc/core/silc-channels.c.
5224 * Fixed the CUMODE_CHANGE notify handling in the server when
5225 server and router are announcing their clients on channels.
5226 Now the mode changes are saved and notified correctly. The
5227 affected file is /silcd/packet_receive.c.
5229 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5230 They really did not replace the cache entry in the ID Cache.
5231 Now they do that. Affected file silcd/idlist.c.
5233 * Fixed the KICK notify handling in the Irssi SILC client to
5234 update the channel records so that the kicked client does not
5235 appear to be on the channel. The affected file is
5236 irssi/src/silc/core/silc-channels.c.
5238 * Always update the conn->current_channel when executing command
5239 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5241 * Fixed the KILL notify handling in Irssi SILC client to remove
5242 the killed client on all channels.
5244 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Fixed the silc_parse_command_line to remove extra spaces
5247 from the start and end of the arguments. Affected file is
5248 lib/silcutil/silcutil.c.
5250 * Cancel and free any active protocol in the function
5251 silc_server_close_connection. Affected file silcd/server.c.
5253 * Cancel and free any active protocol in the function
5254 silc_client_close_connction. Affected file is
5255 lib/silcclient/client.c.
5257 * Do not execute the KILL command for clients that are in
5258 history (ie. they are not in the network). Affected file is
5261 * Fixed KILL notify handling, client does not crash anymore.
5262 Affected file irssi/src/silc/core/silc-channels.c.
5264 * Reduced the default packet buffer size from 2048 to 1024 in
5265 lib/silccore/silcpacket.c.
5267 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5268 counter to the SKE context that is incresed when the SKE library
5269 performs async operation outside the library. If the outside
5270 process frees the SKE context and FREED status will be set
5271 and the library will detect after the sync operation that the
5272 libary is freed. The affected files are
5273 lib/silcske/silcske[_status].[ch].
5275 * Resolve the client entry information in the function
5276 silc_client_channel_message to assure that NULL pointer is not
5277 passed as client entry to the application. */
5279 * Fixed the task timeout calculation to assure that there is
5280 never negative timeouts. The affected file is
5281 lib/silcutil/silcschedule.c.
5283 * Fixed the channel user mode notification sending in server.
5284 It was sent point-to-point to the router (or to server by router)
5285 but it needs to be destined to a channel. The routines now
5286 supports sending the channel user mode notifys to the channels
5287 when announcing clients and channels. Affected files are
5288 silcd/server.c and silcd/packet_receive.c.
5290 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5291 It did not actually replace the old channel entry in the cache.
5292 Affected file lib/silcclient/client_notify.c.
5294 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Fixed a possible crash in silc_packet_send_prepare. It now
5297 assures always that there is enough space in the buffer and
5298 at the tail area of the buffer (for MAC).
5300 Fixed the inbound buffer reallocation in silc_packet_read.
5301 It was old code and did not handle the reallocation correctly.
5304 The affected file is lib/silccore/silcpacket.c.
5306 * Fixed buffer overflow in silc_parse_nickname in the file
5307 lib/silcutil/silcutil.c.
5309 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * make install generates new server keys only if there is not
5314 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5317 Added check that if the NOREPLY is set then we will not send
5318 the away message. This avoids infinite loop of away messages
5319 if both clients are away. The affected file is
5320 lib/silcclient/client_prvmsg.c.
5322 * Fixed client crash if /NICK was given without arguments.
5323 Affected file lib/silcclient/command.c.
5325 * Server does not send the invite list in INVITE command back
5326 to the client if the list was not altered. Added this notion
5327 to the protocol spec as well. Affected file silcd/command.c.
5329 Fixed possible crash in INVITE command by checking the
5330 value of silc_server_get_client_route command.
5332 * Fixed the INVITE notify type handling. The arguments are now
5333 taken in correct order and client does not crash. The affected
5334 file is irssi/src/silc/core/silc-channels.c.
5336 Removed the "Inviting xxx to channel" message from the
5337 client library away and let the application handle it.
5338 Affected file lib/silcclient/command.c. Added that message
5339 to Irssi SILC client's message formats.
5341 * Fixed CMODE command crash in client. It now checks the
5342 amount of arguments correctly and does not crash. The affected
5343 file is lib/silcclient/command.c.
5345 * Do not create new channel automatically in silc_channels_join
5346 but check whether the channel by that name already exists.
5347 Affected file irssi/silc/core/silc-channels.c.
5349 * Do not send the SERVER_SIGNOFF to router if the disconnected
5350 entity was the router. Affected file silcd/server.c.
5352 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5353 SILC client as it was missing from there.
5355 Added the handling of the KICK notify to the Irssi SILC client
5356 as it was missing. Added "you have been kicked" message to
5357 Irssi SILC client's message modules formats.
5359 Added the handing of the KILL notify to the Irssi SILC client
5360 as it was missing. Added the kill message module formats
5363 The affected file is irssi/src/silc/core/silc-channels.c.
5365 * The router did not save the channel mode the server announced.
5366 Affected file silcd/packet_receive.c.
5368 * Fixed a possible crash in INFO command in server. If the
5369 server did not provide the server info it crashed. Affected
5370 file silcd/command.c.
5372 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Fixed the GETKEY command in the server to check also the
5375 global list. Otherwise the GETKEY would not work correctly
5376 in normal SILC server. Affected file silcd/command.c.
5378 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Fixed GETKEY crash, it crashed if the command did not succseed.
5382 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5385 is now real and not just an macro interface to GMP.
5387 Removed the entire GMP from the source tree and imported new
5388 NSS MPI library instead. Reason for removing GMP is that it is
5389 extremely large and compiles extremely slow. The NSS MPI
5390 is only a few files and compiles in less than 10 seconds.
5391 The speed is also about the same as GMP. The MPI is imported
5392 to lib/silcmath/mpi.
5394 If the system has GMP installed we will still use the GMP.
5395 If it is not then the NSS MPI will be compiled.
5397 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Merged a long nickname (127 characters long) crash bugfix from
5400 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5402 * Merged a freed memory reference bugfix from Irssi CVS tree.
5403 Affected file irssi/src/core/commands.c.
5405 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added the server's public key sving and verification to the
5408 server when performing the SKE. This was missing and the
5409 remote server's (or router's) public key was accepted without
5410 checking whether we have it previously or trust it at all.
5411 Affected file silcd/protocol.c.
5413 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Check in the silc_server_timeout_remote if protocol is active
5416 and make sure that the protocol's final callback is called so
5417 that all memory if freed. Affected file silcd/server.c.
5419 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * silc_server_whois_send_reply crashed the server if the nickname
5422 was 127 characters long. Affected file silcd/command.c.
5424 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Added sanity check to the silc_server_new_client. If the hostname
5427 is provided inside username then check that the provided hostname
5428 really is the same as the resolved one. If the hostname was not
5429 resolved then check it from the public key. Affected file is
5430 silcd/packet_receive.c.
5432 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5433 if the server disconnected us and the connection is not valid
5434 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5436 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5437 the library to the lib/silcutil/silcutil.[ch].
5439 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Close log file after open. Affected file
5442 lib/silcutil/silclog.c.
5444 * Check whether sock == NULL in silc_client_send_packet and return
5445 if it is. Affected file lib/silcclient/silcclient.c.
5447 * Check rec->entry == NULL in the Irssi SILC Client before
5448 sending the channel message. Affecte file is
5449 irssi/src/silc/core/silc-servers.c.
5451 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Merged a splitted window bugfix from Irssi CVS tree. The
5454 affected file is irssi/src/fe-text/textbuffer-view.c.
5456 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5457 It did not print nickname.
5459 * Improved the distributions system a bit.
5461 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5464 irssi/src/fe-text/gui-window.c.
5466 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5467 to in-active server. The affected file is
5468 irssi/src/silc/core/client_ops.c.
5470 * Resolve the client in USERS command reply if the entry does
5471 not have username resolved. The affected file is
5472 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5473 command to WHOIS command to really resolve stuff. The USERS
5474 is not used any more in any critical section so WHOIS can
5475 be used even though it might be slower than IDENTIFY.
5477 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5480 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Changed the protocol API a bit more consistent in the
5483 lib/silccore/silcprotocol.[ch].
5485 * Changed the following headers to ROBODoc format:
5487 lib/silccore/silcpayload.h
5488 lib/silccore/silcprotocol.h
5489 lib/silccore/silcsockconn.h
5491 All core library headers are now formatted.
5493 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Fixed a bug in Irssi SILC client; do not show that you are
5496 server/router operator if you really are not. Affected file is
5497 irssi/src/silc/core/client_ops.c.
5499 * Renamed silc_command_free_payload to silc_command_payload_free.
5500 Affected file lib/silccore/silccommand.h
5502 * Added silcmath.h to include the prototoypes of various routines
5503 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5506 * Changed the following headers to ROBODoc format:
5508 lib/silccore/silcchannel.h
5509 lib/silccore/silccommand.h
5510 lib/silccore/silcid.h
5511 lib/silccore/silcidcache.h
5512 lib/silccore/silcmode.h
5513 lib/silccore/silcnotify.h
5514 lib/silccore/silcpacket.h
5515 lib/silcmath/silcmath.h
5517 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added checking to the server code not to start the server if
5520 ciphers and stuff are not configured properly. Affected files
5521 silcd/serverconfig.[h] and silcd/server.c.
5523 * Changed the layout of the header files of the public interfaces
5524 in the SILC libraries. The new layout supports ROBODoc
5525 documentation tool (and some others) so that it is easy to create
5526 a library reference manual. All the other headers and source
5527 code must still follow the CodingStyle document. Also source
5528 code must not include these ROBODoc stuffs, only the headers.
5529 Furthermore, all public interface headers must now be named
5530 by using `silc' prefix, example: silcapi.h, silccipher.h.
5531 Some files were renamed due to this. All the other headers
5532 must not be used as public interfaces. I will update the
5533 CodingStyle document later. Changed following headers, so far:
5535 lib/silcclient/silcapi.h
5536 lib/silccore/silcauth.h
5537 lib/silccore/silcprivate.h
5538 lib/silccrypt/silcdh.h
5540 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Removed silc_client_packet_send_flush from the client library
5545 as it is not needed. Affected file lib/silcclient/client.[ch].
5547 * Added printing of message of unresolved authentication method
5548 to the Irssi SILC client. Added it to the module formats.
5549 Removed the same message from the client library.
5551 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Added new distribution feature, DISTLABEL. Every distribution
5554 can define own preprocessor label that can be used in the
5555 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5556 file distributions, acconfig.h.pre and prepare.
5558 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Added Makefile.defines_int to include the actual definitions
5561 for Makefile.defines.in. Tested the new distribution system,
5562 created distributions and tested installation.
5564 * Added AWAY message printing to the Irssi SILC client. Added
5565 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5567 * Added SCONNECT command to call the SILC's CONNECT command.
5568 Cannot use CONNECT directly since Irssi uses that internally.
5569 Affected file irssi/src/silc/core/silc-servers.c.
5571 Added ACTION local command. It is same as ME command but takes
5572 the channel as mandatory argument.
5574 Rewrote some of the Irssi's help files to suite for SILC
5577 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Added Makefile.defines[.in] that should for now on be included
5580 in all Makefile.am file in the source tree. That file includes
5581 all common compilation definitions for SILC source tree.
5583 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Minor changes to the ./prepare script to change the package
5586 name according the distribution name to the configure.in.
5588 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Created new distribution system. Added file `distributions'
5591 that defines all the distributions that can be created out of
5592 the SILC source tree. The ./prepare script now reads that
5593 file to determine how to prepare the distributions. The
5594 first argument to the ./prepare is the name of the distribution
5595 and second is the version of the distribution. If given
5596 without arguments it creates the default (toolkit) distribution
5597 with the default version (defined in ./prepare).
5599 All Makefile.am files that are subject to the distributions
5600 are now named as Makefile.am.pre. These are ./Makefile.am
5601 and lib/Makefile.am. Others may be changed later.
5603 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Added invite list, ban list, some key management and connection
5606 error message printing to module formats in the Irssi SILC client.
5608 * Added new silc_client_set_away_message to set the away message
5609 that is back to the person who sent private message. The
5610 affected file lib/silcclient/silcapi.h and the
5611 lib/silcclient/client_prvmsg.c.
5613 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * Fixed the private message sending in the Irssi SILC client,
5616 added local command KEY to the Irssi SILC client.
5618 Added key management and key agreement message formats to the
5619 irssi/src/fe-common/silc/module-formats.[ch].
5621 Added USERS (alias WHO) printing, server/router operator
5622 indication and LIST command printing to the module formats.
5624 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Fixed channel joining notify handling, cumode notify handling
5627 from Irssi SILC client.
5629 * Added SILC specific module-formats to the Irssi SILC client so
5630 that SILC specific message hilighting, colors etc is possible.
5631 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5633 Added channel mode, channel user mode, actions, notices,
5634 whois and whowas printing to the the module-formats.c.
5636 * Fixed a bug in channel deletion in the server. The channel
5637 is not left to the cache even if the channel founder auth mode
5638 is set when there are no users anymore on the channel. Affected
5639 file silcd/server.c.
5641 * The silc_net_localhost now resolves the entire hostname including
5642 the domain name. Affected file lib/silcutil/silcnet.c.
5644 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Changed the ask_passphrase client operation to be ascynchronous.
5647 It has now a completion callback and a context that the
5648 application must call after it has got the passphrase from
5649 the user. Affected files lib/silcclient/silcapi.h,
5650 lib/silcclient/protocol.c, lib/silcclient/command.c and
5653 Added SilcAskPassphrase callback that the application calls
5654 to deliver the passphrase to the library.
5656 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5657 The public key verification and especially a certificate
5658 verification is asynchronous procedure.
5660 Added new SILC_SKE_STATUS_PENDING status to indicate the
5661 request is pending and a callback will be called to finalize
5664 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5665 indicate that remote end did not send its public key (or
5666 certificate), even though we require it. Added check for this
5667 condition in the SKE. This was a security bug, now fixed.
5669 Defined new SilcSKEVerifyCbCompletion callback that is called
5670 when the verification process is completed.
5672 The affected files lib/silcske/silcske_status.h and
5673 lib/silcske/silcske.[ch].
5675 * Changed the verify_public_key client operation to be async
5676 as well. Defined SilcVerifyPublicKey callback that is used to
5677 indicate the success of the public key verification process.
5679 Changed the server and client to use the new async client
5682 * Changed the Irssi SILC client's internal scheduler to be called
5683 twice as many times as it used to be. As a result the client
5684 should be a bit faster now. Affected file is
5685 irssi/src/silc/core/silc-core.c.
5687 * Added support to Irssi SILC client of asynchronous public key
5688 verification and passphrase inquiry. Affected file is
5689 irssi/src/silc/core/silc-core.c.
5691 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Do not say "You have left channel %s" in client library.
5694 Moved it to the application. Affected files are
5695 lib/silcclient/command.c and silc/client_ops.c.
5697 * Fixed silc_client_get_clients. Command context was not
5698 duplicated and was freed memory in the callback. Affected
5699 file lib/silcclient/idlist.c.
5701 * Do not say "you are now talking..." on JOIN command in the
5702 client library. The appliation must handle it.
5704 * Do not say ".. changed topic to" in command reply in the
5705 client libary. The application must handle it.
5707 * Fixed TOPIC command sending in the client library.
5709 * Fixed a memory leak in silc_client_command_free in the file
5710 lib/silcclient/command.c.
5712 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Imported a modified version of Irssi client to the source tree.
5715 The Irssi will be used to create a new client called
5716 Irssi SILC. Imported to irssi/.
5718 Added silc_core_init_finish function to the Irssi. Affected
5719 file irssi/configure.in.
5721 A lot changes in the Makefile.ams around the irssi tree.
5723 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Do not rehash if the new size is same as the old size of the
5726 hash table, in the silc_hash_table_rehash*. The affected file
5727 lib/silcutil/silchashtable.c.
5729 * Replaced hash_table_del_by_context calls from the server
5730 (when channel->user_list and client->channels) to the
5731 hash_table_del as it is sufficient and faster.
5733 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Added silc_hash_table_list, silc_hash_table_get and the
5736 SilcHashTableList structure to provide an alternative way to
5737 traverse the hash table. The affected files are
5738 lib/silcutil/silchashtable.[ch].
5740 * Changed the server's idlist routines to use the hash table
5741 routines to optimize the code.
5743 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Replaced the client entry's `channel' list and channel entry's
5746 `user_list' list to hash tables for optimized lookup. Changed
5747 the code to use the hash table interface around the code.
5748 Affected file lib/silcd/idlist.[ch].
5750 * Added `auto_rehash' boolean argument to the function
5751 silc_hash_table_alloc to indicate whether the hash table should
5752 auto-rehash when it thinks is appropriate time. It will
5753 increase the hash table size if the there is twice as much
5754 entries in the table than the size of the table, and will
5755 decrease the size if there are twice as less entries than
5756 the size of the table.
5758 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5762 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * silc_idcache_purge_by_context deletes the entry now by context
5765 as it is supposed to do. Affected file lib/silccore/idcache.c.
5767 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5768 client is not anymore valid (WHOWAS givens the info) and not
5769 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5771 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Removed the `data' and `data_len' arguments from the ID Cache
5774 interfaces and added `name' argument. ID Cache does not handle
5775 anymore the binary data only a names associated with given ID.
5777 * When hashing a Client ID with silc_hash_id the entire ID is
5778 not hashed anymore, instead only the hash of the Client ID is
5779 hashed. This way we can access the Client ID from the cache
5780 with Client ID but with the hash of the ID (which is a hash of
5781 the nickname) as well without any difference in performance.
5783 Added also silc_idcache_find_by_id_one_ext to do one on one
5784 searching when we have the actual ID. Added also function
5785 silc_hash_client_id_compare. The affected files are
5786 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5788 * When hashing the name associated with a ID it is always done
5789 in lowercase. This way we can access the cache without worrying
5790 about case-sensitivity, even though, for example nicknames are
5793 * Fixed a bug in server with channel message sending. It put
5794 wrong ID type as destination ID. The affected file
5795 silcd/packet_send.c.
5797 * silc_idcache_del_by_context now deletes from all hash tables
5798 by context. Affected file lib/silccore/idcache.c.
5800 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Changed the client library to use the new ID Cache interface.
5803 Changes around the source tree.
5805 * Added silc_hash_table_rehash_ext to rehash with specific
5806 hash function. Affected file lib/silcutil/silchashtable.[ch].
5808 * Added silc_hash_string_compare to compare two strings in the
5809 hash table. Affected file lib/silcutil/silcutil.[ch].
5811 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Added new function silc_idcache_del_by_context into the
5814 lib/silccore/idcache.[ch].
5816 * Changed the server's ID list routines to use the new ID Cache
5817 interface. Changes around the source tree.
5819 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Added silc_hash_table_del[_by_context]_ext functions in to the
5822 lib/silcutil/silchashtable.[ch].
5824 Removed silc_hash_table_find_all* routines and added new
5825 silc_hash_table_find_foreach to replace them.
5827 Added silc_hash_table_replace_ext function as extended
5828 replacing function. Separated the simple hash table interface
5829 from the extended hash table interface in the file
5830 lib/silcutil/silchashtable.h.
5832 * Fixed minor bugs and changed it to use some of the new
5833 hash table functions in lib/silccore/idcache.c
5835 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added new function silc_hash_table_find_all to return all keys
5838 in the hash table by the specified key. As the hash table is
5839 collision resistant it also makes it possible to have several
5840 duplicate keys in the hash table. This function may be used to
5841 find all of the keys from the hash.
5843 Added user_context arguments to the SilcHashFunction,
5844 SilcHashCompare and SilcHashDestructor to deliver user specified
5847 Added new fuctions silc_hash_table_find[_all]_ext to do
5848 extended lookup with specified hash and compare functions and
5849 specified user contexts.
5851 Added new function silc_hash_table_add_ext to add the key
5852 with specified hash function and user context.
5854 Added new function silc_hash_table_foreach to traverse all
5855 entrys in the hash table. Added SilcHashForeach callback
5858 Added new function silc_hash_table_del_by_context to delete
5859 the entry only if the context associated with the key matches.
5861 Affected files are lib/silcutil/silchashtable.[ch].
5863 * Removed silc_hash_[server/client/channel]_id and added just
5864 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5865 silc_hash_id_compare to compare two ID's using as the hash table
5866 comparison function. Added also silc_hash_data to hash
5867 binary data and silc_hash_data_compare to compare it.
5869 * Removed silc_idlist_find_client_by_hash as it is not needed
5870 anymore. Affected file silcd/idlist.[ch].
5872 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5873 to use internally the SilcHashTable. The new ID Cache is a lot
5874 faster than the old one. Some of the ID Cache interface was also
5875 rewritten and obsolete and stupid functions were removed.
5877 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added entry_count field to the SilcHashTable to keep the number
5880 of the entries in the table. Implemented the function
5881 silc_hash_table_rehash. Added new function
5882 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5884 Fixed a minor bug in silc_hash_table_free.
5886 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5887 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5888 into the lib/silcutil/silcutil.[ch].
5890 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Implemented a collision resistant hash table into the
5893 lib/silcutil/silchashtable[ch]. See the header and the source
5894 for the SilcHashTable API.
5896 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Merged dotconf version 1.0.2 into lib/dotconf.
5900 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Do not compile anything in lib/silcsim/* if the SIM support
5903 is not enabled. The tree should now compile without problems
5906 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Compiled the SILC under cygwin. Compiled and tested briefly
5909 without problems. More tests needed. The SIMs didn't compile
5912 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5914 * Fixed possible crash in silc_get_username in the
5915 lib/silcutil/silcutil.c.
5917 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Fixed a va_arg in silc/client_ops.c.
5921 * Oops, RC5 routines were named AES and caused some problems
5922 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5924 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added new SilcIDIP structure into the lib/silccore/id.h and
5927 replaced the old `ip' fields from all SILC ID's to that type.
5928 This is a step towards IPv6 support.
5930 The silc_id_get_len takes now the ID as an extra argument.
5931 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5932 both IPv4 and IPv6 based ID's.
5934 The affected files are lib/silccore/id.[ch] and other files
5935 around the tree using these routines.
5937 * Removed the ID length arguments in server from various
5938 silc_server_send_notify_* routines -> they are not needed
5941 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Fixed memory leak in silc_encode_pem_file in the file
5944 lib/silcutil/silcutil.c.
5946 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Check minor version as well in the SKE. Affected files are
5949 silcd/protocol.c and lib/silcclient/protocol.c.
5951 * Added --identifier option to the server so that an identifier
5952 can be when creating the public key for the server. Affected
5953 file is silcd/silcd.c.
5955 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5956 lib/silccrypt/silcpkcs.c.
5958 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Register default ciphers and stuff when using -C option with
5961 the server. Affected file sildc/silcd.c.
5963 * Put back the servers public key filename format, it is better
5964 than the new one. For now, the client keys are saved with the
5965 new filename format. The affected file silc/client_ops.c.
5967 * Implemented the Cipher API for the rest of the ciphers that
5968 did not implement it or implemented it the wrong way.
5970 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Register default ciphers and stuff when using the -S option
5973 in the client. Affected file silc/silc.c. Same also when
5974 creating new key pair with -C option.
5976 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Fixed the silc_verify_public_key client operation function to
5979 save the public keys differently. The fingerprint is now
5980 used as filename and not the hostname. This way also the
5981 client keys are saved uniquely and not with hostnames. The
5982 affected file is silc/client_ops.c.
5984 * Trimmed the silc_hash_fingerprint function to remove extra
5985 whitespaces from the end of the fingerprint. The affected
5986 file is lib/silccrypt/silchash.c.
5990 * Added silc_cipher_register_default function to register all
5991 default ciphers. It can be used when configuration files
5992 does not exist and the application does not want any specific
5993 ciphers in any specific order.
5995 The SilcDList is now used as silc_cipher_list dynamically
5996 allocated cipher list. Removed the static list all together
5997 and now all ciphers must be allocated to the dynamic list.
5998 The silc_cipher_alloc routine was changed to check only the
6001 All silc_cipher_* routines that used to return int returns
6004 The affected files lib/silccrypt/silccrypt.[ch].
6006 * The same thing was done to silc_hash_* as for silc_cipher_*
6007 routines. Affected files lib/silccrypt/silchash.[ch].
6009 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6010 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6011 Added also silc_pkcs_[un]register[_default] functions.
6012 Removed the data_context from the PKCS API.
6014 * Added silc_hmac_register_default function to register default
6015 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6016 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6017 to unregister all hmacs at once.
6019 * Register the default ciphers, hash functions, PKCSs and HMACs
6020 if client's configuration file does not exist. The affected
6023 * The client did not load the hash functions from the SIM
6024 modules at all. Added support for this. Affected file is
6025 silc/clientconfig.c.
6027 * When decoding public key with silc_pkcs_public_key_decode, check
6028 the supported algorithm only if PKCS are registered. Affected
6029 file lib/silccrypt/silcpkcs.c. The same was done with the
6030 silc_pkcs_private_key_decode.
6032 * Fixed the SILC List routines to keep the list always in order.
6033 It used to change the list's order when traversing the list but
6034 not it preserves the order. Affected file lib/trq/silclist.h.
6036 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Added the client library to use the SilcSocketConnection's
6039 reference counter (by silc_socket_dup) to prevent the bug that
6040 the socket object may be freed underneath async operation.
6042 * The name resolv library checking fixes in the configure.in.pre.
6045 * Created new version of the protocol drafts for future
6046 development. The -03 drafts are the ones that will be changed
6047 in the trunk now and the -02 will remain as they are.
6049 * Send list of CUMODE notifys to the router when announcing
6050 the channel users to the router. Affected file silcd/server.c.
6051 If the router receiving channel founder CUMODE for a channel
6052 that already has channel founder it will send CUMODE notify
6053 to the sender to remove the channel founder rights from the
6054 announced client. Affected file silcd/packet_receive.c.
6056 * The CUMODE notify may now use Server ID as well as the entity
6057 who changes the mode. Updated protocool specs.
6059 * Updated INSTALL and README files.
6061 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * New web pages in the http://silc.pspt.fi. The pages was
6068 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Implemented the [DenyConnectin] config section in the server.
6071 Added silc_server_config_denied_conn to check whether incoming
6072 connection is denied. Affected file silcd/serverconfig.[ch].
6074 * Do not check the ports when checking the incoming configuration
6075 data if the port is 0, meaning any. Affected file is
6076 silcd/serverconfig.c.
6078 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Fixed buffer overflow in silc_string_compare in the file
6081 lib/silcutil/silcutil.c.
6083 * Fixed double free in silc_server_command_leave in the file
6086 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Fixed the version checking in the server. Affected file is
6091 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Fixed the configuration data fetching when accepting new
6094 connections in the server. Affected file silcd/server.c.
6096 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Added `sender_entry' argument to the function
6099 silc_server_packet_relay_to_channel so that we can check
6100 whether some destination actually belongs to the same route
6101 the sender belongs (ie, we must not resend the packet to the
6102 sender). Affected file silcd/packet_send.[ch].
6104 * Added `servername' field to the SilcClientEntry in the server
6105 to hold the name of the server where client is from. Affected
6106 file is silcd/idlist.h.
6108 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Moved the channel message encrypting in the router betwen
6111 router connections from silc_server_channel_message to the
6112 silc_server_packet_relay_to_channel since we want to check
6113 whether we have anybody channel before encrypting anything.
6114 Affected files silcd/packet_[receive/send].c.
6116 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Fixed the [AdminConnection] server config section to support
6119 multiple entries. Affected file silcd/serverconfig.c.
6121 * Added support into the server to check the validity of the
6122 incoming connection before executing any KE or authentication
6125 * The connection configuration is now saved to the KE and
6126 connection auth protocol contexts and not fetched anymore in
6127 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6129 * The local hosts listenning address and port is also resolved
6130 now when starting the server. We want to have the socket object
6131 to include the real address and port for the listener. Added
6132 new function silc_net_check_local_by_sock into the files
6133 lib/silcutil/silcnet.[ch].
6135 * Fixed a broadcast bug in server -> do not broadcast if we
6138 * Fixed a routing bug. Do not route broadcast packets ever.
6139 Broadcast packets must be processed always and not routed since
6140 they may be destined to some other host than yourself and thus
6141 would get routed without no good reason. Affected file is
6144 * Added function silc_server_config_is_primary_route to check
6145 whether primary router connection has been configured (a router
6146 configuration that we are initiating). If there is not, we
6147 will assume that there is only two routers in the SILC network
6148 and we will use the incoming router connection as our primary
6149 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6151 * Changed the order of the broadcasting. Broadcast _after_ the
6152 packet has been processed not before. Affected file is
6155 * Fixed a [ClientConnection] parsing bug. The port was never
6156 parsed correctly thus resulting to port 0. Affected file
6157 silcd/serverconfig.c.
6159 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6160 argument and did not set the broadcast packet flag. Affected
6161 file silcd/packet_send.c. Fixed same bug in the function
6162 silc_server_send_notify as well.
6164 * If we receive NEW_ID packet for our own ID in the server, ignore
6167 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Removed the nickname from the Private Message Payload.
6172 Updated the code and the protocol specs.
6174 * Updated protocol specs for submitting to the IETF.
6176 * Tweaked the Random Number Generator a bit. Affected file
6177 lib/silccrypt/silcrng.c. Exported a new function
6178 silc_rng_[global]_add_noise which can be used to add more
6181 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Do not parse packets with different timeout when protocol
6184 is active -> may cause problem with rekey. Affected file
6187 * When server receives signoff notify it must not create
6188 new channel key if the client is on any channels since the
6189 sender of the signoff notify will create it.
6191 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Added printing of error messages during SKE protocol from the
6194 failure packet sent by server during SKE. Affected file
6197 * Removed the client's failure_callback handling with timeout
6198 and handle it immediately when received.
6200 * The SKE library returned wrong type in SUCCESS and FAILURE
6201 packets. They must be 32 bit MSB not 16 bit MSB.
6203 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * Ok, rewrote the logic of the re-key and now it seems to work.
6206 I tested it on high traffic with frequent re-keys without
6207 problems. Added hmac_receive (and renamed hmac to hmac_send)
6208 in SilcClientConnection in lib/silcclient/client.h and
6209 in SilcIDListData in silcd/idlist.h. Also, removed the
6210 SilcPacketParserContext's cipher and hmac fields as they are
6211 not needed anymore and actually caused some problems when
6212 the ciphers and hmac's changed underneath the packet parser.
6214 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * If re-key protocol is active then process the incoming packets
6217 synchronously since we must assure that icoming packets encrypted
6218 with the old key is processed before the new keys is set to
6219 use. This is true other packets than for REKEY packets.
6220 Affected file silcd/server.c. The same was done to client library
6221 as well, affected file lib/silcclient/client.c.
6223 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Fixed bug in client and server to accept the force send if
6226 the packet is send from silc_[server/client]_packet_process
6227 function. Otherwise the packets are never delivered, oops.
6229 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Disable force sending of packets when REKEY protocol is active.
6232 We must assure that no packet is sent directly when rekey is
6233 performed. All packets must be sent through packet queue.
6234 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6235 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6236 function is silc_[server/client]_packet_send_real to check
6239 * Replaced the SIM paths from example config files to
6240 /usr/local/modules. Also, make install creates now
6241 /usr/local/silc/logs directory to hold all the SILC server
6244 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Made the configure.in.pre work on Solaris. Patch by salo.
6248 * Made all ciphers compatible with non-x86 machines. Defined
6249 CBC mode macros into lib/silccrypt/ciphers_def.h.
6251 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Fixed the make install.
6255 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * When MAC computation fails the silc_packet_decrypt returned 0
6258 even though it was supposed to return -1. Fixed this. The
6259 affected file is lib/silccore/silcpacket.c.
6261 * Do not replace the config files in /etc/silc (in make install)
6262 if they already exist. Affected file ./Makefile.am.
6264 * Do not send re-key packets immediately but through packet queue.
6265 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6267 * Changed silc_net_check_host_by_sock to return FALSE if the
6268 IP/DNS could not be resolved. Though, it returns the IP address
6269 now even if it could not resolve it (but returns also FALSE).
6270 Affected file lib/silcutil/silcnet.[ch].
6272 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6280 contents of the specified public key file.
6282 * Changed the PKCS api to return the public key length when
6283 setting the public key.
6285 * Fixed a fatal bug in the public and private key file loading.
6286 Affected file lib/silccrypt/silcpkcs.c.
6288 * Execute the packet parsing for client with zero (0) timeout
6289 if the protocol is active. Affected file silcd/server.c.
6291 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Made the key generation options to the silcd program. Added
6294 -C option, equivalent to client's option.
6296 * Added new [ServerKeys] config section to the server. It
6297 configures the server's public and private key.
6299 * Defined generic Public Key Payload into the protocol
6300 specification to send specific type of public keys and
6303 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6304 public key or certificate.
6306 * Implemented the GETKEY command to the server and to the
6307 client library and on user interface.
6309 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6313 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Added SilcServerRekey context into silcd/idlist.h.
6317 * Added the PFS support as defined in the specification to the
6318 SKE protocol. Affected files lib/silcske/*.c.
6320 * Added `ske_group' field to the SilcServerRekey context to hold
6321 the number of the SKE group that is used with PFS in re-key.
6322 Affected file silcd/idlist.h.
6324 * Added PFS re-key support to the server. Affected file is
6327 * Added silc_protocol_cancel to cancel execution of the next
6328 state of the protocol. Affected file is
6329 lib/silccore/silcprotocol.[ch].
6331 * Added the re-key support with and without PFS to the client
6332 library. Re-key is performed once in an hour, by default.
6334 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6335 Added silc_client_rekey_callback and silc_client_rekey_final.
6336 Affected files are lib/silcclient/protocol.[ch] and
6337 lib/silcclient/client.[ch].
6339 * Removed the `hmac_key' and `hmac_key_len' fields from the
6340 SilcClientConnection structure; not needed. Affected file is
6341 lib/silcclient/client.h.
6345 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Do not ask whether user wants to use the negotiated private key
6348 for private messages, just use it. Affected file is
6349 silc/local_command.c.
6351 * Added `send_enc_key' and `enc_key_len' fields to the
6352 SilcIDListData structure since they are needed in the re-key
6353 phase. Affected file is silcd/idlist.[ch].
6355 * Implemented the simple re-key protocol into the server.
6356 Affected files silcd/server.c and silcd/protocol.[ch]. The
6357 re-key will be performed once in an hour, by default.
6359 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6360 Added silc_server_rekey, silc_server_rekey_callback and
6361 silc_server_rekey_final.
6363 * Removed Tunneled flag from the protocol. Updated the code
6364 and the specifications.
6366 * Adde `pfs' field to the SilcIDListData to indicate whether
6367 the PFS is to be performed in the re-key. Affected file is
6370 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6373 int64 of at least the xintXX size. If void * is less that 4
6374 bytes uint32 * will be used. Defined bool as boolean.
6376 * Changed _ALL_ unsigned long and unsigned int to uint32,
6377 unsgined short to uint16 in the source tree.
6379 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6380 not handle clients that has entry->data.registered == FALSE.
6381 They are not in the network anymore. Affected file is
6384 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * Implemented the sending of the SERVER_SIGNOFF notify in the
6387 server. Affected file is silcd/server.c.
6389 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6390 Added also silc_notify_payload_encode_args into the
6391 lib/silccore/silcnotify.[ch].
6393 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6394 Affected file silcd/packet_receive.c.
6396 * Implemented the SERVER_SIGNOFF notify handling in the client
6397 library. Affected file lib/silcclient/client_notify.c. Also,
6398 implemnted the printing of the SERVER_SIGNOFF info to the
6399 application. Affected file silc/client_ops.c.
6401 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6402 if the deleting was successful. Affected file silcd/idlist.[ch].
6404 * Added support for public key authentication in the connection
6405 authentication protocol in the client library. Affected file
6406 lib/silcclient/protocol.c.
6408 * Changed the server's silc_idlist_get_clients_by_* interface
6409 to support already allocated array so that new entries may be
6410 added to pre-allocated array. Affected file silcd/idlist.[ch].
6411 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6412 and command replies.
6414 * All command reply functions in the server now calls the
6415 pending command callback even if error occured. This way the
6416 error will be delivered to the client as well. Affected files
6417 silcd/command.c and silcd/command_reply.c.
6419 * Fixed INFO command to return local server's info if no server
6420 was provided. Affected file lib/silcclient/command.c.
6422 * Removed RESTART command for good. Updated the code and the
6425 * Rewrote parts of the task system. It is a bit simpler now.
6426 Removed unsued task priorities. The affected files are
6427 lib/silcutil/silctask.[ch].
6429 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Moved the USERS printing from the library to the application.
6432 Affected files lib/silcclient/command.c and silc/client_ops.c.
6434 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Added channel key re-key support. The re-key is perfomed
6439 only by the router and is done once in an hour. Added `rekey'
6440 field to the SilcChannelEntry in the server. Affected files
6441 silcd/server.c and silcd/idlist.h.
6443 * Added silc_task_unregister_by_context into the file
6444 lib/silcutil/silctask.[ch].
6446 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Added SILC_UMODE_GONE mode to indicate when the client is not
6449 present in the SILC network. Added also support to the local
6450 command AWAY that will set this mode. Added support of showing
6451 "xxx is gone" in WHOIS command. The USERS command shows the
6452 gone status as well.
6454 * Fixed setting server and router operator privileges in the
6455 server's UMODE command. Affected file silcd/command.c.
6457 * Merged the SKE KE1 and KE2 payloads into one payload. The
6458 new KE payload is equivalent to the old KE2 payload.
6460 Cleaned up the SKE Start Payload parsing. It now uses the
6461 simple buffer unformatting to do the parsing. A lot faster
6464 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6465 to the SKE that is used to indicate whether both of the SKE
6466 parties should perform authentication. By default only the
6467 responder performs authentication. By setting this flag also
6468 the initiator must do authentication. By default it is unset
6469 since in normal SKE case, client to server connection, only
6470 the responder should do authentication. When doing SKE between
6471 two clients both should perform authentication. Updated the
6472 code and the protocol specs.
6474 * A little fix to IDENTIFY command in the server. Search the
6475 client first by hash not nickname. Affected file is
6478 * Fixed the silc_client_close_connection to support closing
6479 the client to client connections wihtout deleting too much
6480 data. Affected file lib/silcclient/client.c.
6482 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6483 are received if protocol used to be active but is not anymore
6484 the application would crash due to NULL pointer dereference.
6485 Affected files silcd/server.c and lib/silcclient/client.c.
6487 * Added `hash' field to the SilcClientConnection to include
6488 the hash function negotiated in the SKE protocol.
6490 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6491 to set the channel founder authentication data. A client can
6492 claim the founder rights later by providing the authentication
6493 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6494 This way the channel founder can regain the channel founder
6495 privileges even it is left the channel. This works only on
6496 local server and the client must be connected to the same
6497 server to be able to regain the founder rights. Updated the
6498 protocol specs accordingly.
6500 Added support to the CMODE command in the client to set the
6501 founder auth data. Read the README to see how to set it.
6503 Added support to the CUMODE command to claim the founder
6504 rights. Read the README to see how to do it.
6506 Added support for the founder authentication to the Channel
6507 Entry in the server. Affected file silcd/idlist.h.
6509 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6510 server's CMODE command. Affected file silcd/command.c.
6512 * Added the following new functions into lib/silccore/silcauth.[ch]:
6513 silc_auth_get_method and silc_auth_get_data.
6515 * The server now saves the remote hosts public key to the
6516 SilcIDListData pointer. Affected file silcd/protocol.c.
6518 * The normal server now does not remove the channel entry from
6519 the cache if the founder authentication data is set. It used
6520 to remove it if the founder was the last one on the channel on
6521 the server and left the channel. The auth data is saved and
6522 if the channel is re-joined later the old entry is used with
6523 the old auth data. Affected files silcd/command_reply.c and
6526 * Removed the `pkcs' field from the SilcIDListData structure
6527 in the server; it is not used. Affected file silcd/idlist.h.
6529 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Fixed packet processing on slow links. Partial packets were
6532 never re-processed because the incoming data buffer was cleared
6533 by the application. Application must not directly clear the
6534 sock->inbuf, the packet processing routines handle it. Fixed
6535 this in client library and in server.
6537 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * Fixed the WHOIS and IDENTIFY send reply function to really
6540 check whether to send list or just one entry. Affected file
6543 * Cleaned up the LEAVE command's channel key distribution. The
6544 affected file silcd/command.c.
6546 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6547 can enforce the channel mode as well. In that case the ID
6548 includes the ID of the server. The code now enforces the
6549 mode change if the router have different mode than the server.
6551 * The notify client operation with CMODE_CHANGE notify can now
6552 return NULL client_entry pointer if the CMODE was not changed
6553 by client. Application must check for this.
6555 * Added <Server ID> argument to INFO command to support server
6556 info fetching by Server ID.
6558 * Added silc_server_announce_get_channel_users to get assembled
6559 packets of channel users of the specified channel. Affected
6560 file silcd/server.[ch].
6562 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6563 was freed underneath the ID Cache.
6565 * Re-announce clients when the server received CHANNEL_CHANGE
6566 notify from the router. Affected file silcd/packet_send.c.
6568 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6571 crashed since it did not handle the fact that there is no cipher
6572 called "3" and didn't check the error condition. Now fixed.
6574 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6575 flag. It can be used to send message requests.
6577 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Implemented the RESTART command in the client.
6581 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6582 notice type messages. Added notice printing to the user
6585 * The channel keys are not re-generated if the channel's mode
6586 is PRIVKEY, ie private key on the channel exists. Affected
6587 files silcd/server.c and silcd/command.c.
6589 * Fixed a little bug in channel message delivery when channel
6590 private keys are set in the server. Affected file is
6591 silcd/packet_send.c.
6593 * Changed the setting on channel->on_channel = TRUE from the
6594 silc_client_save_channel_key to the JOIN command reply. The
6595 key payload is not received if the private channel key is set.
6596 Affected file lib/silcclient/command_reply.c and the
6597 lib/silcclient/client_channel.c.
6599 * When the CMODE_CHANGE notify is sent and the channel private
6600 key mode is removed the channel key must be re-generated in
6601 other cells as well. Added this support for the router in the
6602 silcd/packet_receive.c.
6604 * Added new local command NOTICE to send notice message on
6605 channel. Affected file silc/local_command.[ch].
6607 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Added new local command ME to the client. It is used to send
6610 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6611 some action. Affected file silc/local_command.[ch].
6613 * Changed channel_message and private_message client operations
6614 to deliver the message flags to the application. Added also
6615 the `flags' arguments to the silc_client_send_channel_message
6616 and silc_client_send_private_message functions. Affected file
6619 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Redefined the Private Message Payload to support private message
6622 keys and to support the new private message flags. Updated
6623 the protocol specs. Flags makes it possible to have for example
6624 CTCP style messages.
6626 * Added new type SilcPrivateMessagePayload and defined an API
6627 for it in the lib/silcclient/silcprivate.[ch].
6629 * Tested private message private keys successfully. Tested the
6630 private message key set, unset and list commands with the new
6633 * Redefined the Channel Message Payload to include the channel
6634 message flags (equal with private message flags) to support
6635 for example CTCP style messages.
6637 * Defined some of the message (for channel and private message)
6638 flags. Updated the protocol specs and added the flags to the
6639 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6641 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * Added SilcKeyAgreementStatus type to the key agreement routines
6644 to indicate the current status and error if one occured.
6645 The status types are defined in the lib/silcclient/silcapi.h.
6647 * Added new local command KEY that is used to set and unset private
6648 keys for channels, set and unset private keys for private messages
6649 with remote clients and to send key agreement requests and
6650 negotiate the key agreement protocol with remote client. The
6651 key agreement is supported only to negotiate private message keys,
6652 it currently cannot be used to negotiate private keys for channels,
6653 as it is not convenient for that purpose.
6655 * Fixed a minor pending callback setting bug in the function
6656 silc_client_get_client_by_id_resolve, now the function works.
6657 Affected file lib/silcclient/idlist.c.
6659 * Added function silc_net_get_local_port to get local bound
6660 port by socket. Added to lib/silcutil/silcnet.[ch].
6662 * Added `sockets' and `sockets_count' fields to the SilcClient
6663 object. They hold the sockets of the listenning sockets in
6664 the client. Listenning sockets may be for example the key
6665 agreement server. Affected file lib/silcclient/client.[ch].
6666 Added functions the silc_client_add_socket and the
6667 silc_client_del_socket. They are exported to the application
6670 * Added ~./silc/clientkeys to support other client's public keys.
6672 * Renamed verify_server_key client operation to verify_public_key
6673 and added one argument to indicate the type of the connection
6674 (server, client etc.).
6676 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6678 * Added silc_server_connection_auth_request to handle the
6679 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6680 silcd/packet_receive.[ch].
6682 * Added silc_server_send_connection_auth_request into the
6683 silcd/packet_send.c to send the connection auth request packet.
6685 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6688 * Fixed the public key authentication in responder side in the
6689 server. The `auth_data' pointer includes the SilcPublicKey
6690 not the path to the public key. Affected file silcd/protocol.c.
6692 * Implemented the public key authentication in the initiator side
6693 in the server. Affected file silcd/protocol.c.
6695 * Removed the [RedirectClient] config section from the server
6696 configuration. Is not needed and I don't want to implement it.
6698 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Cleaned up the CMODE command in the server. It now works
6701 correctly and supports all the modes defined in the protocol.
6702 Affected file is silcd/command.c.
6704 * Added `hmac_name' field to the SilcChannelEntry in the server
6705 to hold the default HMAC of the channel. It can be set when
6706 creating the channel (with JOIN command). Affected files
6709 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6710 type to indicate the change of the current cipher and hmac
6711 on the channel. Client can safely ignore the <cipher> argument
6712 (if it chooses to do so) since the CHANNEL_KEY packet will
6713 force the channel key change anyway. The <hmac> argument is
6714 important since the client is responsible of setting the new
6715 HMAC and the hmac key into use.
6717 * Fixed the CMODE command in the client library as well.
6719 * Tested CMODE command in router environment successfully.
6721 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Show the version of the remote client (or server) when connecting
6724 to the server. It is logged to the log file. Affected file
6725 is silcd/protocol.c.
6727 * Fixed the KILLED notify handling in the client library. The
6728 client must be removed from all channels when receiving the
6731 Also, do not remove the client entry when giving the KILL
6732 command but when the KILLED notify is received.
6734 * Removed silc_idlist_find_client_by_nickname from the server.
6735 Not needed anymore. Affected files silcd/idlist.[ch].
6737 * Implemented the CHANNEL_CHANGE notify type handling to the
6738 server. Affected file silcd/server.c.
6742 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Added silc_server_send_notify_invite to send the INVITE
6745 notify between routers.
6747 * Implemented the INVITE command correctly to the server.
6749 * Implemented the INVITE notify type handling in the server.
6751 * Implemented the INVITE command to the client library and on the
6754 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added function silc_server_get_client_resolve to find the
6757 client entry by ID from all ID lists and then resolve it
6758 (using WHOIS) if it cannot be found. Affected file is
6761 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Implemented the BAN command to the client library.
6765 * The JOIN command in the server now checks the invite list
6768 * Changed the silc_command_reply_payload_encode_va and the
6769 silc_command_payload_encode_va to support that if argument is
6770 NULL it ignores and checks the next argument. Affected file
6771 lib/silccore/silccommand.c.
6773 * Added silc_server_send_notify_ban to send the BAN notify
6774 type between routers.
6776 * Chaned the silc_notify_payload_encode to support that if
6777 argument is NULL it ignores and checks the next argument.
6778 Affected file lib/silccore/silcnotify.c.
6780 * Tested ban lists in router environment successfully.
6782 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6784 * Implemented BAN command to the server, in silcd/command.[ch].
6786 * Removed the BAN and INVITE_LIST modes from the CMODE command
6789 * Added function silc_string_match to regex match two strings.
6790 Affected files lib/silcutil/silcutil.[ch].
6792 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Redefined parts of the SilcChannelEntry in the server to support
6795 the new ban and invite lists.
6797 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6799 * Redefined the INVITE command. The same command can be used to
6800 invite individuals to the channel but also to manage the invite
6801 list of the channel (to add to and remove from the invite list).
6802 Updated the protocol specs.
6804 * Added new command SILC_COMMAND_BAN that can be used to manage
6805 the ban list of the channel. Updated the protocol specs.
6807 * Removed the channel modes: the SILC_CMODE_BAN and the
6808 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6809 in the CMODE command. The equivalent features are now available
6810 using INVITE and BAN commands. Updated the protocol specs.
6812 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6813 in the network about change in the current ban list. The notify
6814 type is not used by the client.
6816 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6817 support the invite lists.
6819 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Added new function silc_string_regexify that converts string
6822 including wildcard characters into regex string that can
6823 be used by the GNU regex library. Added into the file
6824 lib/silcutil/silcutil.[ch].
6826 Added silc_string_regex_combine to combine to regex strings
6827 into one so that they can be used as one regex string by
6828 the GNU regex library. Added into the file
6829 lib/silcutil/silcutil.[ch].
6831 Added silc_string_regex_match to match two strings. It returns
6832 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6834 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Imported GNU regex to the soruce tree into lib/contrib.
6837 Fixed some compiler warning from the regex.c.
6839 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Fixed MOTD command in the server to work in router environment.
6843 * Fixed the MOTD command in the client library to support
6844 the server argument in the command.
6846 * Added `nickname_len' argument to the silc_idlist_add_client
6847 in the server, as the `nickname' argument may be binary data
6850 * Added silc_idlist_get_channels to return all channels from
6853 * Implemented LIST command to the server. Affected file is
6856 * Implemented the LIST command to the client library and on the
6859 * Added [<user count>] argument to the LIST command reply.
6860 With private channels the user count is not shown.
6862 * Updated TODO and README.
6864 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * The client entry's data.registered must be TRUE even with
6867 global client entry on global client list. The data.registered
6868 is used to check whether the client is anymore in the network,
6869 for example with WHOWAS command so it must be valid.
6871 * Fixed the WHOWAS command in the server. It now actually works
6872 in router environment. Added function into silcd/command_reply.c
6873 silc_server_command_reply_whowas_save.
6875 * Added silc_idlist_purge function to the silcd/idlist.c
6876 to periodically purge the ID Cache.
6878 * Fixed INFO command in the server. It works now in router
6879 environment. Added <server name> argument to the INFO command
6880 reply. Updated the protocol specs.
6882 * Fixed minor bug in silc_idcache_purge to not purge if the
6883 expire value is zero.
6885 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6886 they were buggy because of the WHOWAS information.
6888 * Fixed local command MSG to handle the async resolving of
6889 the remote client properly. It used to fail the first MSG.
6890 Affected file silc/local_command.c.
6892 * Added `data_len' field to SilcIDCache context.
6894 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Update TODO. Todo in commands in the server.
6898 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6901 used by routers as broadcast packet to inform other routers
6902 about the changed user mode.
6904 Implemented the notify handling in the server. Affected file is
6905 silcd/packet_receive.c. Added the function
6906 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6908 * Added new generic Channel Payload and deprecated the New Channel
6909 Payload. The New Channel Payload is now the generic Channel
6912 * Added new argument `mode' to the silc_server_send_new_channel
6913 as it is required in the Channel Payload now.
6915 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6916 and created a new and real SilChannelPayload to represent the
6917 new generic Channel Payload. Implemented the encode/decode
6918 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6920 * Added silc_server_get_client_channel_list to return the list
6921 of channels the client has joined for WHOIS command reply.
6922 Affected file silcd/server.[ch].
6924 * Implemented the channel list sending in the WHOIS command reply
6925 in server and in the client.
6927 Implemented the channel list displaying on the user interface
6928 as well. Affected file silc/client_ops.c.
6930 * Added silc_channel_payload_parse_list to parse list of Channel
6931 Payloads. It returns SilcDList list of SilcChannelPayloads.
6932 Client for example can use this function to parse the list of
6933 channels it receives in the WHOIS command reply. The caller
6934 must free the list by calling silc_channel_payload_list_free.
6935 Affected files lib/silccore/silcchannel.[ch].
6937 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6939 * Added one new argument <user mode> to the WHOIS command reply
6940 to return the mode of the user in SILC. Updated the protocol
6943 Implemented it to the server and client.
6945 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Fixed the mode printing on the user interface on joining.
6948 Affected file silc/client_ops.c.
6950 * Implemented the UMODE command and user modes in general to the
6951 client library and to the user interface.
6953 * Implemented the UMODE command to the server.
6955 * The server now sends UNKNOWN_COMMAND error status if client sends
6956 unknown command. Affected file silcd/command.c.
6958 * All server commands now handle the command identifier the right
6959 way when sending the command reply to the client. The client can
6960 use to identify the command replies with the identifier.
6962 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6964 * Added silc_server_get_client_route to resolve the route to
6965 the client indicated by the client ID. Affected file is
6968 * Added silc_server_relay_packet as general function to relay
6969 packet to arbitrary destination. This deprecates functions
6970 like _send_private_message_key, _relay_notify etc. Affected
6971 file is silcd/packet_send.[ch].
6973 Removed silc_server_send_key_agreement,
6974 silc_server_send_private_message_key and
6975 silc_server_packet_relay_notify functions from the file
6976 silcd/packet_send.[ch].
6980 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6981 server. Affected file silcd/packet_receive.[ch].
6983 * Implemented the KILL command to the client. Implemented the
6984 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6985 Affected files lib/silcclient/command[_reply].c and
6986 lib/silcclient/client_notify.c. Implemented the KILL notify
6987 printing in the user inteface.
6989 * Fixed a lot silc_parse_nick memory leaks from the client
6990 library in the file lib/silcclient/command.c.
6992 * Changed the silc_server_send_notify_on_channels's `sender'
6993 argument from SilcSocketConnection to SilcClientEntry to
6994 check the sender as entry and not as connection object and not
6995 to send to the client provided as argument. The affected file
6996 is silcd/packet_send.[ch].
6998 * The notify packets that are destined directly to the client used
6999 to not to be processed by the server. Now changed that and the
7000 server processes all notify packets. After relaying the packet
7001 to the client the notify packet is processed in the server.
7003 * The silc_server_free_client_data now checks whether there is
7004 pending outgoing traffic for the client and purges the data to
7005 the network before removing the client entry.
7007 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7010 an client is killed from the SILC Network. Updated the protocol
7013 Added new function silc_server_send_notify_killed to the
7014 silcd/packet_send.[ch].
7016 * Added function silc_server_packet_relay_notify to relay notify
7017 packets that are destined directly to a client. In this case
7018 the server does not process the notify packets but merely relays
7019 it to the client. Affected file silcd/packet_send.[ch].
7021 Added also silc_server_packet_process_relay_notify to check
7022 whereto relay the notify. Affected file is
7023 silcd/packet_receive.[ch].
7025 * Implemented the KILL command to the server.
7029 * Added the backup schema desgined last fall to the protocol
7030 specs for everyone to see. The specification is in the
7031 *-spec-xx.txt draft and the packet type definitions for the
7032 backup routers is in *-pp-xx.txt draft. Thusly, added also
7033 new packet type SILC_PACKET_CELL_ROUTERS.
7035 * A big security problem in the implementation discovered. The
7036 signoff of an client did not cause new channel key generation
7037 which it of course should've done. The channel keys must be
7038 always re-generated when client leaves (or signoffs) the channel.
7039 The silc_server_remove_from_channels funtion now handles
7040 the channel key re-generation.
7042 * Added `sender' argument to the silc_server_send_notify_on_channels
7043 to not to send the client provided as argument. Affected file
7044 silcd/packet_send.[ch].
7046 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7048 * Implemented OPER and SILCOPER commands into the server and
7051 * Added silc_auth_verify and silc_auth_verify_data to verify
7052 the authentication directly from the authentication payload.
7053 It supports verifying both passphrase and public key based
7054 authentication. Affected file lib/silccore/silcauth.[ch].
7056 * Added `hash' field to the SilcIDListData structure. It is the
7057 hash negotiated in the SKE protocol. Affected file is
7060 * Slight redesigning of the SilcAuthPayload handling routines.
7061 Do not send SilcPKCS but SilcPublicKey as argument.
7063 * Implemented the public key authentication support to the
7064 serverconfig. The public key is loaded from the provided path
7065 and saved as authentication data to void * pointer. Thus,
7066 changed the unsigned char *auth_data to void *auth_data;
7068 * Fixed SHUTDOWN command to send the reply before the server
7069 is shutdown. :) Affected file silcd/command.c.
7071 * Fixed fatal bug in CONNECT command. The hostname was invalid
7072 memory and server crashed. Affected file silcd/command.c.
7074 * Fixed fatal bug in CLOSE command. The server_entry became
7075 invalid but was referenced later in the command. Affected file
7078 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Fixed fatal bug in failure packet handling. Server ignored
7081 the failure and thus crashed when it came.
7085 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7087 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7088 that the command may be executed only once in (about) 2 seconds.
7089 The old SILC_CF_LAG flag is same but allows command bursts up
7090 to five before limiting.
7092 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7093 server code. Various commands now includes the CF_LAG_STRICT
7094 flag to disallow any kind of miss-use of the command.
7096 * Fixed the silc_buffer_unformat to not to allocate any data
7097 if the length of the data is zero. It used to allocate the
7098 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7100 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Changed the format of AdminConnection configuration section
7103 in the server. Added username of the admin to the format.
7104 Affected files silcd/serverconfig.[ch].
7106 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7107 to return admin configuration data by host, username and/or
7110 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Implemented WHOWAS command to the server. Added the functions:
7114 silc_server_command_whowas_parse,
7115 silc_server_command_whowas_send_reply,
7116 silc_server_command_whowas_from_client and
7117 silc_server_command_whowas_from_server
7119 * Added <Client ID> argument to the WHOWAS command reply. Updated
7120 the protocol specs accordingly.
7122 * Implemented WHOWAS command and command_reply to the client
7125 Implemented the WHOWAS printing on the user interface.
7127 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Added new argument to the WHOWAS command reply, the real name.
7130 It is an optional argument. Updated the protocol specs.
7132 * Added SilcIDCacheDestructor callback that is registered when
7133 the SilcIDCache is allocated. The callback is called when
7134 an cache entry in the ID Cache expires, or is purged from the
7135 cache. Added into lib/silccore/idcache.[ch].
7137 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7138 to destruct the client entries when the cache entry expires.
7139 Other ID Cache's in server and in the client library ignores
7142 * If the ID Cache entry's `expire' field is zero then the entry
7143 never expires. Added boolean `expire' argument to the
7144 silc_idcache_add function in the lib/silccore/idcache.[ch].
7145 If it is TRUE the default expiry value is used.
7147 * Added silc_server_free_client_data_timeout that is registered
7148 when client disconnects. By default for 5 minutes we preserve
7149 the client entry for history - for WHOWAS command.
7151 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Added support to the server to enforce that commands are not
7154 executed more than once in 2 seconds. If server receives
7155 commands from client more frequently, timeout is registered
7156 to process the commands. Affected file silcd/command.c.
7157 Added new function silc_server_command_process_timeout.
7159 * Changed NICK_NOTIFY handling in client library to check that
7160 if the client's nickname was changed, so there is no need to
7161 resolve anything from the server.
7163 * Removed error printing from the WHOIS and IDENTIFY commands.
7164 If error occurs then it is ignored silently in the client library.
7165 The application, however, may map the received error to
7166 human readable error string. The application currently maps
7167 the NO_SUCH_NICKNAME error to string.
7169 * Made the command status message public to the application. Moved
7170 them from lib/silcclient/command_reply.c to
7171 lib/silcclient/command_reply.h. The application can map the
7172 received command status to the string with the
7173 silc_client_command_status_message function.
7175 * Added check to the server to check that client's ID is same
7176 as the Source ID in the packet the client sent. They must
7179 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Added dist-bzip hook to the Makefile.am to make bzip2
7182 compressed distributions.
7184 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7186 * Server now enforces the maximum length for the nickname and
7187 the channel as protocol specification dictates. 128 bytes for
7188 nickname and 256 bytes for channel name.
7190 * Moved the WHOIS printing to the application. The client libary
7191 does not print out the WHOIS information anymore, the application
7192 must do it. Renamed silc_client_command_reply_whois_print to
7193 the silc_client_command_reply_whois_save.
7195 The client's idle time is also sent to the application now, and
7196 the idle is shown on screen.
7198 * Added silc_client_command_reply_identify_save to save the
7199 received IDENTIFY entries.
7201 * Do not check for channel private keys in message sending and
7202 reception if the channel does not have the PRIVKEY mode set.
7203 Affected file lib/silclient/client_channel.c.
7205 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7208 just surfaced after chaning the JOIN procedure.
7210 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Added silc_client_get_clients_by_list to get client entries
7213 from Client ID list, that is returned for example by JOIN
7214 and USERS command replies. The application should use this
7215 function for example when JOIN command reply is received to
7216 resolve the clients already on the channel (library does not
7217 do that anymore as USERS command reply is not used in the JOIN
7218 procedure anymore). Affected files lib/silcclient/silcapi.h and
7219 lib/silcclient/idlist.c.
7221 * JOIN command reply and USERS command reply returns now SilcBuffer
7222 pointers instead of unsigned char pointers when returning
7223 the client list and mode list.
7225 * Added <Client ID> argument to the JOIN command reply, mainly
7226 for the server to identify for which client the command was
7227 originally sent. Updated protocol specs accordingly.
7229 * Added SilcDlist private_key pointer to the SilcChannelEntry
7230 in the client to support the channel private keys. Affected
7231 file is lib/silcclient/idlist.h.
7233 * Added SilcChannelPrivateKey argument to the function
7234 silc_client_send_channel_message so that application can choose
7235 to use specific private ke if it wants to. If it is not provided,
7236 the normal channel key is used, unless private keys are set.
7237 In this case the first (key that was added first) is used
7238 as the encryption key.
7240 * Implemented the support for channel private key handling.
7241 Implemented the following functions:
7243 silc_client_add_channel_private_key,
7244 silc_client_del_channel_private_keys,
7245 silc_client_del_channel_private_key,
7246 silc_client_list_channel_private_keys and
7247 silc_client_free_channel_private_keys
7249 Affected file lib/silcclient/client_channel.c.
7251 * Added the support for the private keys in the channel message
7252 sending and encryption and in the message reception and
7253 decryption. Affected funtions are
7254 silc_client_send_channel_message and silc_client_channel_message.
7256 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Added SKE's key verify callback to the client library's
7259 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7261 * Removed the statement that server (or router) must send USERS
7262 command reply when joining to the channel so that the client
7263 knows who are on the channel. Instead, the client list and
7264 client's mode list is now sent in the JOIN command reply to the
7265 client who joined channel. This is better solution.
7267 * Added function silc_server_get_users_on_channel and function
7268 silc_server_save_users_on_channel to the silcd/server.[ch].
7270 * Removed function silc_server_command_send_users from the
7273 * Do not show topic on the client library anymore. The topic is
7274 sent in the command reply notify to the application and the
7275 application must show the topic now.
7277 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Added client searching by nickname hash into the IDENTIFY and
7280 WHOIS commands in the server as they were clearly missing from
7281 them. Affected file is silcd/command.c.
7283 * Fixed a bug in private message receiving in the client library.
7284 The remote ID was freed and it wasn't supposed, now it is
7287 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7289 * Minor fix to the channel payload; allocate the data area, as it
7290 needs to be of specific length.
7292 * If the key agreement port is zero then the operating
7293 system will define the bound port. Affected files are
7294 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7296 * Added new function silc_channel_payload_decrypt into the file
7297 lib/silccore/silcchannel.[ch].
7299 * Moved the channel message etc, check from silc_packet_decrypt
7300 to applications. The library calls now a generic
7301 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7302 when the packet is either normal or special. This was done to
7303 allow more wide range of checking that was not allowed when
7304 the code was in library. Now applications can do virtually any
7305 checks to the packet and return to the library the decision how
7306 the packet should be processed. Affected files are
7307 lib/silccore/silcpacket.[ch].
7309 Added silc_server_packet_decrypt_check to the server and
7310 silc_client_packet_decrypt_check to the client library.
7312 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7313 to send with specified source and destination information.
7315 * Channel message delivery between routers was broken after the
7316 channel key distribution was fixed earlier. The channel key
7317 was used be to distributed to other routers as well which is not
7318 allowed by the protocol. Now this is fixed and channel keys
7319 really are cell specific and the channel message delivery between
7320 routers comply with the protocol specification.
7322 * Fixed various commands in server to check also the global list
7323 for the channel entry and not just the local list. The affected
7324 file silcd/command.c.
7326 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Added assert()s to buffer formatting and unformatting routines
7329 to assert (if --enable-debug) when error occurs. Affected
7330 file: lib/silcutil/silcbuffmt.c.
7332 * Changed to auto-reconnect to check whether the remote host is
7333 router and register the re-connect timeout if it is. It used
7334 to check that whether we are normal server, but router must do
7335 auto-reconnect with another router as well. Affected file
7338 * Removed the [<key len>] option from CMODE command as the cipher
7339 name decides the key length, nowadays. See the defined ciphers
7340 from the protocol specification.
7342 * Added [<hmac>] option to the CMODE command to define the HMAC
7343 for the channel. Added SILC_CMODE_HMAC channel mode.
7345 * Added [<hmac>] option for the JOIN command so that user can
7346 select which HMAC is used to compute the MACs of the channel
7349 * Added Hmac field to the Channel Message Payload. The integrity
7350 of plaintext channel messages are now protected by computing
7351 MAC of the message and attaching the MAC to the payload. The
7352 MAC is encrypted. Now, it is clear that this causes some
7353 overhead to the size of the packet but rationale for this is that
7354 now the receiver can verify whether the channel message decrypted
7355 correctly and also when private keys are set for the channel the
7356 receiver can decrypt the packet with several keys and check from
7357 the MAC which key decrypted the message correctly.
7359 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7360 lib/silccrypt/silccipher.[ch].
7362 * Added silc_hash_len to return the digest length into the
7363 lib/silcrypt/silchash.[ch].
7365 * Rewrote parts of Silc Channel Payload interface in the
7366 lib/silccore/silcchannel.[ch]. The encode function now also
7367 encrypts the packet and parse function decrypts it.
7369 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * Fixed a minor formatting bug in the SKE's key material processing.
7372 It actually might have processed the keys wrong way resulting
7375 * Redefined the mandatory HMAC algorithms and added new algorithms.
7376 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7377 and hmac-md5 truncated to 96 bits. The mandatory is now
7378 hmac-sha1-96. Rest are optional (including the one that used
7379 to be mandatory). Rationale for this is that the truncated HMAC
7380 length is sufficient from security point of view and can actually
7381 make the attack against the HMAC harder. Also, the truncated
7382 HMAC causes less overhead to the packets. See the RFC2104 for
7385 * Added new [hmac] configuration section. The SKE used to use
7386 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7387 is of course wrong. The official names that must be proposed in
7388 the SKE are the ones defined in the protocol specification
7389 (hmac-sha1-96 for example). The user can configure any hmac
7390 using any hash function configured in the [hash] section. At
7391 least, the mandatory must be configured.
7393 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7395 * Added HMAC list to the SKE proposal list. It has now both
7396 hash algorithm list and HMAC list. This makes the protocol
7397 incompatible with previous versions. The SKE now seems to work
7398 the way it is supposed to work, for the first time actually.
7400 * Defined plain Hash algorithms to the protocol specification.
7403 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Implemented support for key agreement packets into the server.
7406 Added functions silc_server_key_agreement and
7407 silc_server_send_key_agreement. Other than these functions,
7408 server has nothing to do with this packet.
7410 * Added support for private message key packets into the server.
7411 Added functions silc_server_private_message_key and
7412 silc_server_send_private_message_key.
7416 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7417 called in the protocol's final callback instead in the END
7418 protocol state. This makes a little more sense and in the same
7419 time in client we can use the same protocol routines for normal
7420 key exchange and to key agreement packet handling as well.
7422 * Added to both client's and server's KE protocol context the
7423 SilcSKEKeyMaterial pointer to save the key material. We will
7424 bring the key material to the protocol's final callback by doing
7425 this. The final callback must free the key material.
7427 * Added SKE's packet_send callback into client's KE protocol
7428 context so that the caller can choose what packet sending function
7429 is used. This way we can use different packet sending when
7430 doing normal SKE when doing key agreement packet handling (in
7431 the key agreement packet handling we do not want to encrypt
7434 * Implemented the responder side of the key agreement routines
7435 in the client. The client can now bind to specified port and
7436 accept incoming key negotiation. The key material is passed
7437 to the application after the protocol is over.
7439 * Implemented the processing of incoming Key Agreement packet
7440 in the client. Added function silc_client_key_agreement to
7443 * Implemented the intiator side of the key agreement routines
7444 in the client. The client can now initiate key agreement with
7445 another remote client. The key material is passed to the
7446 application after the protocol is over.
7448 * Created client_keyagr.c to include all the key agreement
7451 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7452 SILC_TASK_CALLBACK except that it is not static.
7454 * Created client_notify.c and moved the Notify packet handling
7455 from the client.[ch] into that file.
7457 * Created client_prvmsg.c and moved all private message and
7458 private message key routines from the client.[ch] into that file.
7460 * Create client_channel.c and moved all channel message and
7461 channel private key routines from the client.[ch] into that file.
7463 * Changed silc_client_get_client_by_id_resolve to resolve with
7464 WHOIS command instead of IDENTIFY command, in the file
7465 lib/silclient/idlist.c.
7467 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7469 * Implemented the SKE's responder side to the Client library.
7471 * When FAILURE is received to the protocol do not trust it
7472 blindly. Register a timeout to wait whether the remote closes
7473 the connection as it should do it, only after that process the
7474 actual failure. This was changed to both client and server.
7476 * Added client_internal.h to include some of the structures
7477 there instead of client.h in lib/silcclient/.
7479 * Added function silc_task_unregister_by_callback to unregister
7480 timeouts by the callback function.
7482 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7484 * Some "Incomplete WHOIS info" errors has been appearing on the
7485 log files. Took away the entry->userinfo check from WHOIS
7486 reply sending. The entry->userinfo is now " " if client did not
7487 provide one. I thought this was fixed earlier but something
7488 is wrong still. Let's see if the error still appears.
7490 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * Fixed a minor bug in the login when the channel key is
7493 re-generated in the server. It used to generate the key in
7494 wrong order and thus caused problems in the channel traffic.
7496 * Fixed a minor bug in channel key distsribution after
7497 KICK command. The key was not sent to the router even though
7500 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7502 * Added silc_ske_process_key_material_data as generic routine
7503 to process any key material as the SILC protocol dictates. The
7504 function is used by the actual SKE library but can be used by
7505 applications as well. This relates to the private message keys
7506 and the channel private keys since they must be processed the
7507 same way the normal SILC session keys. The protocol dictates
7508 this. Affected files: lib/silcske/silcske.[ch].
7510 Added also silc_ske_free_key_material to free the
7511 SilcSKEKeyMaterial structure.
7513 * Defined silc_cipher_set_key function to set the key for
7514 cipher without using the object's method function. The affected
7515 files: lib/silccrypt/silccipher.[ch].
7517 * Implemented silc silc_client_add_private_message_key,
7518 silc_client_add_private_message_key_ske,
7519 silc_client_del_private_message_key,
7520 silc_client_list_private_message_keys and
7521 silc_client_free_private_message_keys functions in the
7524 Added functions silc_client_send_private_message_key to send
7525 the Private Message Key payload and silc_client_private_message_key
7526 to handle incoming Private Message Key payload.
7528 * Added Cipher field to the Private Message Key payload to set
7529 the cipher to be used. If ignored, the default cipher defined
7530 in the SILC protocol (aes-256-cbc) is used.
7532 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Removed lib/silcclient/ops.h file.
7536 Redefined parts of the SILC Client Library API. Created new
7537 file silcapi.h that deprecates the ops.h file and defines the
7538 published Client Library API. Defined also private message key
7539 API and channel private key API into the file.
7541 This is the file that the application must include from the
7542 SILC Client Library. Other files need not be included by
7543 the application anymore.
7545 * Added new key_agreement client operation callback and also
7546 defined the Key Agreement library API for the application.
7548 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7551 is used by clients to request key negotiation between another
7552 client in the SILC network. If the negotiation is started it
7553 is performed using the SKE protocol. The result of the
7554 negotiation, the secret key material, can be used for example
7555 as private message key.
7557 Implemented the Key Agreement payload into the files
7558 lib/silccore/silauth.[ch].
7560 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7562 * Redefined ciphers for the SILC protocol. Added some new ciphers
7563 and defined the key lengths for the algorithms. Changed the
7564 code accordingly. The default key length is now 256 bits.
7566 * Fixed SKE key distribution function silc_ske_process_key_material
7567 when the key length is more than 128 bits. The default key
7568 length in SILC is now 256 bits.
7570 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7571 to indicate unsupported algorithm.
7573 * Renamed rijndael.c to aes.c and all functions as well.
7575 * Fixed a long standing channel key setting bug in client library.
7576 Weird that it has never surfaced before.
7578 * Fixed bug in channel deletion. If the entire channel is removed
7579 then it must also delete the references of the channel entry
7580 from the client's channel list as the client's channel entry and
7581 the channel's client entry share same memory.
7583 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7585 * Implemented CONNECT and SHUTDOWN commands in the client.
7587 * Implemented CLOSE command to the client.
7589 * Added the function silc_idlist_find_server_by_name into the
7590 files silcd/idlist.[ch].
7592 Added the function silc_idlist_find_server_by_conn into the
7593 files silcd/idlist.[ch].
7595 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * DIE command was renamed to SHUTDOWN. Updated the both code
7600 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7601 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7603 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7606 * Added function silc_server_create_connection function to create
7607 connection to remote router. My server implementation actually
7608 does not allow router to connect to normal server (it expects
7609 that normal server always initiates the connection to the router)
7610 so the CONNECT command is only good for connecting to another
7613 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7615 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7616 or some other client was kicked from the channel.
7618 Implemented the handling of the notify type to both client
7621 Implemented silc_server_send_notify_kicked to send the KICKED
7622 notify. It is used to send it to the server's primary router.
7624 * Implemented the KICK command into server and client.
7626 * Added `query' argument to the silc_idlist_get_client function
7627 to indicate whether to query the client from server or not if
7630 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7631 to indicate that the client is not channel founder.
7635 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7637 * Removed the rng context from SilcPacketContext structure and
7638 changed that the packet routine uses the Global RNG API.
7640 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Added support for quit message that client can "leave" on the
7643 channel when it quits the SILC. It is ditributed inside the
7644 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7646 Added silc_server_free_client_data that will take the
7647 signoff message as argument.
7649 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7651 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Updated parts of the protocol specification to keep it up
7656 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7659 payloads in one packet.
7661 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7662 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7663 use now the new List flag.
7665 * Also deprecated the following packet types: REPLACE_ID,
7666 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7668 * Added list support for Notify packet in server.
7670 * Added silc_server_send_notify_channel_change to send the
7671 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7672 the silc_server_send_replace_id.
7674 * Added silc_server_send_notify_nick_change to send the
7675 NICK_CHANGE notify type. Deprecates the function
7676 silc_server_send_replace_id.
7678 * Added silc_server_send_notify_join to send the JOIN notify type.
7679 Deprecates the function silc_server_send_new_channel_user.
7681 * Added silc_server_send_notify_leave to send LEAVE notify type.
7682 Deprecates the function silc_server_send_remove_channel_user.
7684 * Added silc_server_send_notify_cmode and
7685 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7686 types. Deprecates the silc_server_send_set_mode function.
7688 * Added SERVER_SIGNOFF notify type to indicate that server has
7689 quit. This means that all clients on the channel from that
7690 server will drop. This can be also used when netsplit happens.
7692 Deprecated REMOVE_ID packet type since it is not needed anymore
7695 Added silc_server_send_notify_server_signoff to send the
7696 SERVER_SIGNOFF notify type. Deprecates the function
7697 silc_server_send_remove_id.
7699 Added also silc_server_send_notify_signoff to send the
7700 SIGNOFF notify type.
7702 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7703 SILC protocol from this day on. Changed the protocol
7704 specification as well.
7706 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7707 notify type. It is used between routers to notify about
7708 topic changes on a channel.
7710 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7713 * Partly updated the protocol specification to comply with the
7714 changes now made. It is still though a bit outdated.
7716 * The JOIN notify type now takes one extra argument <Channel ID>.
7717 The packet used to be destined to the channel but now the
7718 JOIN type may be sent as list thus it is impossible to
7719 destine it to any specific channel. By adding this argument
7720 it is again possible.
7722 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7724 * Added CREDITS file. The CHANGES and CREDITS file will appear
7725 in the distribution as well.
7727 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7729 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7730 types in the server's silcd/packet_receive.c.
7732 * Implemented CMODE and CUMODE to work in router environment.
7734 * Fixed minor encoding and decoding buglet from the
7735 lib/silccore/silcmode.c.
7737 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7740 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7742 * Changed all SilcConfigServer* and silc_config_server* to
7743 SilcServerConfig* and silc_server_config*, respectively.
7746 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7748 * Associated the ID (client or server ID) to the Authentication
7749 Payload to avoid any possibility of forging. Updated the
7750 protocol specification and the code accordingly.
7752 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7754 * The RSA key length is now save to the RsaKey context in the
7755 key generation process in lib/silccrypt/rsa.c. The key length
7756 is now used to figure out the maximum size of the block allowed
7757 to be encrypted/signed.
7759 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7760 is equivalent to the silc_mp_mp2bin but does not allocate any
7763 * Changed silc_mp_mp2bin API to take length argument. If it is
7764 non-zero then the buffer is allocated that large. If zero, then
7765 the size is approximated using silc_mp_sizeinbase, which however
7768 * Created Global RNG API which is global RNG that application can
7769 initialize. After initializing, any routine anywhere in the
7770 code (including library) can use RNG without allocating a new
7771 RNG object. This was done to allow this sort of use of the
7772 RNG in code that has no chance to allocate RNG object. All
7773 applications currently allocate this and many routines in the
7774 library use this. Affected file lib/silccrypt/silcrng.[ch].
7776 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7777 it to use the Global RNG API.
7779 * Defined Authentication Payload into protocol specification that
7780 is used during SILC session to authenticate entities. It is
7781 used for example by client to authenticate itself to the server
7782 to obtain server operator privileges.
7784 Implemented this payload into the lib/silccore/silcauth.[ch].
7785 Implemented also routines for public key based authentication
7786 as the new protocol specification dictates.
7788 Moved definitions of different authentication methods from
7789 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7791 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7792 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7793 silc_pkcs_verify_with_hash functions into the file
7794 lib/silccrypt/silcpkcs.[ch].
7796 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7798 * The client entry's userinfo pointer must be always valid.
7799 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7800 will fail since it requires the userinfo. Now, the userinfo
7801 is allocated as "" if actual userinfo does not exist. Actually,
7802 it must exist and it is totally Ok to drop client connections
7803 that does not announce the userinfo. However, we will make
7804 this workaround for now.
7806 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7807 to return the remote port by socket.
7809 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7811 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7812 SILC_SERVER_PENDING_EXEC and added an new macro
7813 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7814 data or when error occurs while processing the pending command.
7816 Added new argument `destructor' into silc_server_command_pending
7817 and to the SilcServerCommandPending object. This destructor is
7818 now called after calling the pending callback or if error occurs
7819 immediately. If error occurs the actual pending callback won't
7820 be called at all - only the destructor. The destructor may be
7821 NULL if destructor is not needed.
7823 All this applies for client library code as well. Similar
7824 changes were made there as well for the pending commands.
7826 In the client, the application must now allocate the
7827 SilcClientCommandContext with the silc_client_command_alloc
7830 * Added reference counter to the SilcServerCommandContext. Added
7831 function silc_server_command_alloc and silc_server_command_dup
7834 Same type of functions added to the client library for the same
7837 * Removed the cmd_ident from IDListData away since it is now
7838 global for all connections. It is the command identifier used
7839 in command sending and with pending commands. The affected file
7842 * Added reference counter to the SilcSocketConnection objecet to
7843 indicate the usage count of the object. The object won't be
7844 freed untill the reference counter hits zero. Currently only
7845 server uses this, and client ignores it. The client must be
7846 set to use this too later. The affected files are
7847 lib/silccore/silcsockconn.[ch]. Added also the function
7848 silc_socket_dup to increase the reference counter.
7850 This was mainly added because it is possible that the socket
7851 is removed underneath of pending command or other async
7852 operation. Now it won't be free'd and proper DISCONNECTING
7853 flags, etc. can be set to avoid sending data to connection that
7854 is not valid anymore.
7856 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7857 the connection. After that it sets SILC_SET_DISCONNECTED.
7858 It is, however, possible that the socket data is not still freed.
7859 The silc_server_packet_process now checks that data is not
7860 read or written to connection that is DISCONNECTED. The socket
7861 get's freed when the reference counter hits zero.
7863 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7865 * Changed the client operation API: channel_message operation's
7866 `sender' is now the client entry of the sender, not the nickname
7867 and the `channel' is the channel entry, not the channel name.
7869 In the private_message operation the `sender' is now also the
7870 client entry of the sender not the nickname.
7872 Affected file is lib/silcclient/ops.h and all applications
7873 using the client operations.
7875 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7877 * Moved the calling of ops->connect() from connect_to_server_final
7878 into receive_new_id functin since that is the point when the
7879 client is actually allowed to send traffic to network. The
7880 affected file is lib/silcclient/client.c.
7882 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7884 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7885 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7886 (if needs broadcasting) instead of broadcasting the packets one
7887 by one which would make a burst in the network traffic.
7889 * Added `broadcast' argument to the functions in silcd/server.[ch]
7890 silc_server_create_new_channel[_with_id] to indicate whether
7891 to send New Channel packet to primary router.
7893 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7895 * Added new function into the silcd/server.[ch] files:
7896 silc_server_create_new_channel_with_id to create new channel with
7897 already existing Channel ID.
7899 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7900 lib/silccore/silcpacket.h. This packet is used t send list of
7901 Set Mode payloads inside one packet. Server uses this to set
7902 the modes for the channels and clients on those channels, that it
7903 announced to the router when it connected to it. The protocol
7904 specification has been updated accordingly.
7906 * The silc_server_new_channel did not handle the packet coming
7907 from normal server as it normally does not send that. However,
7908 when it announces its channels it does send it. Implemented
7909 the support for that.
7911 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7912 into the file lib/silccore/id.h.
7914 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7916 * Fixed memory leaks in the functions silc_idlist_del_client,
7917 silc_idlist_del_channel and silc_idlist_del_server in the file
7918 silcd/idlist.c. All of those leaked like a sieve.
7920 * Fixed some small memory leaks in the client's function
7921 silc_client_notify_by_server.
7923 * Added functions into silcd/server.c: silc_server_announce_clients,
7924 silc_server_announce_channels and silc_server_announce_server.
7925 These functions are used by normal and router server to announce
7926 to its primary router about clients, channels and servers (when
7927 router) that we own. This is done after we've connected to the
7930 These functions effectively implements the following packet types:
7931 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7932 and SILC_PACKET_NEW_ID_LIST.
7934 * Added new functions into the silcd/packet_receive.[ch]:
7935 silc_server_new_id_list, silc_server_new_channel_list and
7936 silc_server_new_channel_user_list to handle the incoming
7937 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7939 * Added support of changing Channel ID in the function
7940 silc_server_replace_id. If the server that announces a channel
7941 to the router already exists in the router (with same name but
7942 with different Channel ID), router is responsible to send
7943 Replace ID packet to the server and force the server to change
7944 the Channel ID to the one router has.
7946 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7947 client that the Channel ID has been changed by the router. The
7948 normal server sends this to the client. Client must start using
7949 the new Channel ID as the channel's ID.
7951 Implemented handling of this new type into lib/silcclient/client.c
7952 into the function silc_client_notify_by_server.
7954 * Added new function silc_idlist_replace_channel_id into the files
7955 silcd/idlist.[ch] to replace the Channel ID.
7957 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7959 * Call silc_server_command_identify_check always when processing
7960 the IDENTIFY command in silcd/command.c
7962 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7964 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7965 send keepalive packets. The packet can be sent by clients,
7966 servers and routers.
7968 Added function silc_socket_set_heartbeat into the file
7969 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7970 If not set, the heartbeat is not performed. The actual
7971 heartbeat is implemented in the low level socket connection
7972 library. However, application is responsible of actually
7975 Added silc_server_send_heartbeat to send the actual heartbeat
7976 packet into silcd/packet_send.[ch]. Server now performs
7977 keepalive with all connections.
7979 * Added silc_task_get_first function into lib/silcutil/silctask.c
7980 to return the timeout task with shortest timeout. There was a bug
7981 in task unregistration that caused problems. TODO has been
7982 updated to include that task system must be rewritten.
7984 * The client library will now resolve the client information when
7985 receiving JOIN notify from server for client that we know but
7986 have incomplete information.
7988 * Rewrote parts of silc_server_remove_from_channels and
7989 silc_server_remove_from_one_channel as they did not remove the
7990 channel in some circumstances even though they should've.
7992 * Encryption problem encountered in server:
7994 The LEAVE command used to send the Channel Key packet to the
7995 router immediately after generating it. However, the code
7996 had earlier sent Remove Channel user packet but not immediately,
7997 ie. it was put to queue. The order of packets in the router
7998 was that Channel Key packet was first and Remove Channel User
7999 packet was second, even though they were encrypted in the
8000 reverse order. For this reason, MAC check failed. Now, this
8001 is fixed by not sending the Channel Key packet immediately but
8002 putting it to queue. However, this is more fundamental problem:
8003 packets that are in queue should actually not be encrypted
8004 because packets that are sent immediately gets encrypted
8005 actually with wrong IV (and thus MAC check fails). So, packets
8006 that are in queue should be encrypted when they are sent to
8007 the wire and not when they put to the queue.
8009 However, the problem is that the current system has not been
8010 designed to work that way. Instead, the packet is encrypted
8011 as soon as possible and left to the queue. The queue is then
8012 just purged into wire. There won't be any fixes for this
8013 any time soon. So, the current semantic for packet sending
8016 o If you send packet to remote host and do not force the send
8017 (the packet will be in queue) then all subsequent packets to the
8018 same remote host must also be put to the queue. Only after the
8019 queue has been purged is it safe again to force the packet
8022 o If you send all packets immediately then it safe to send
8023 any of subsequent packets through the queue, however, after
8024 the first packet is put to queue then any subsequent packets
8025 must also be put to the queue.
8027 Follow these rules and everything works fine.
8029 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8031 * Added new function silc_server_remove_clients_by_server to
8032 remove all client entries from ID list when the server connection
8033 is lost. In this case it is also important to invalidate all
8034 client entires as they hold the invalid server entry. This
8035 fixes fatal bug when server has lost connection and will reconnect
8038 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8040 * Made some sanity checks to silc_server_daemonise like to check
8041 whether the requested user and group actually exists.
8043 * Added sanity check to SKE's silc_ske_responder_finish to check
8044 that the public and private key actually is valid.
8046 * Invalidate the client's nickname when receiving Replace ID
8047 packet and the Client ID is being replaced. This means that the
8048 server will query the nickname if someone needs it (client)
8051 * Sort the ID Cache in client library when the ID Cache data
8052 has changed (needs sorting).
8054 * Do not allow for SILC client to create several connections to
8055 several servers. The client does not support windows right now
8056 and generating multiple connections causes weird behaviour.
8058 Irssi-silc client does support windows and can handle several
8059 connections without problems, see: www.irssi.org and SILC plugin.
8061 * Fixed some places where client was added to the IDList. The
8062 rule of thumb is following (in order to get everything right):
8063 If the client is directly connected local client then the
8064 `connection' argument must be set and `router' argument must be
8065 NULL to silc_idlist_add_client function. If the client is not
8066 directly connected client then the `router' argument must
8067 bet set and the `connection' argument must be NULL to the
8068 silc_idlist_add_client function.
8070 * The funtion silc_server_packet_send_local_channel actually did
8071 not check whether the client was locally connected or not. It
8072 does that now. Fixed a bug related to LEAVE command.
8074 * Fixed Remove Channel User payload parsing bug in server's
8075 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8077 * The server's silc_server_save_channel_key now checks also the
8078 global ID list for the channel as it might not be in the local
8079 list. Fixed a bug related to LEAVE command.
8081 * Is this the end of the [<unknown>] buglet that has been lurking
8082 around for a long time? A little for loop fix in server's
8083 silc_server_command_whois_parse that is used by both IDENTIFY
8084 and WHOIS command. At least, this was a clear bug and a cause
8085 of one type of [<unknown>] buglet.
8087 * WHOIS and IDENTIFY commands call the function
8088 silc_server_command_[whois/identify]_check function even if
8089 we are not router server.
8091 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8093 * Added --with-gmp configuration option. If set the GMP
8094 is always compiled in the SILC source tree. If not set then
8095 it is checked whether the system has the GMP3 installed. If
8096 it has then the GMP won't be compiled (the system's headers
8097 and library is used), if it doesn't have it then the GMP is
8098 compiled in the SILC source tree.
8100 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8102 * Changed RSA private exponent generation to what PKCS #1
8103 suggests. We try to find the smallest possible d by doing
8104 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8105 not security fix but optimization.
8107 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * Added new config entry [Identity] to fork the server and run
8110 it as specific user and group. A patch from Bostik.
8112 * Imported Dotconf configuration library into lib/dotconf.
8113 This will be used to create the SILC configuration files later.
8114 It will appear in the distsribution after this commit.
8116 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8118 * A big code auditing weekend happening. Auditing code for
8119 obvious mistakes, bugs and errors. Also, removing any code
8122 Removed files for being obsolete:
8124 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8125 inline in the file lib/silcutil/silcbuffer.h)
8127 o lib/silcutil/silcbufutil.c (the header has inline versions)
8129 Changed code to fix possible error conditions:
8131 o The buffer formatting routines now check that the destination
8132 buffer really has enough space to add the data. This applies for
8133 both buffer formatting and unformatting
8134 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8135 unformatting was changed to accomodate following rules:
8136 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8137 sent to the function while XXX_*STRING will not allocate or copy
8138 the data into the buffer. Instead it sets the pointer from the
8139 buffer into the pointer sent as argument (XXX_*STRING used to
8140 require that the pointer must be allocated already). This change
8141 makes this whole thing a bit more consistent and more optimized
8142 (note that the data returned in the unformatting with XXX_*STRING
8143 must not be freed now). The routines return now -1 on error.
8145 o Tried to find all code that use buffer_format and buffer_unformat
8146 and added return value checking to prevent formatting and
8147 especially unformatting errors and possible subsequent fatal
8150 o Changed ske->x and ske->KEY to mallocated pointers in
8151 lib/silcske/silcske.h. Fixed possible data and memory leak.
8153 o Added return value checking to all *_parse* functions. Fixed
8154 many memory leaks as well.
8156 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8157 so that buffer overflows would not happen. All code now also
8158 checks the return value as it can fail.
8160 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8162 * Added reconnection support to server if the normal server looses
8163 its connection to the router (for example if router is rebooted).
8164 The server performs normal reconnection strategy implemented
8165 to the server. Affected file silcd/server.c.
8167 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8169 * Added new packet type SILC_PACKET_SET_MODE that is used to
8170 distribute the information about changed modes (for clients,
8171 channels and clients channel modes) to all routers in the
8172 network. Updated the protocol specification accordingly.
8174 Added functions into silcd/packet_send.c and
8175 silcd/packet_receive.c: silc_server_send_set_mode,
8176 silc_server_set_mode.
8178 Added new files silcmode.[ch] into lib/silccore that implements
8179 the encoding and decoding of Set Mode Payload. Added new type
8180 SilcSetModePayload. Moved the definitions of different modes
8181 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8183 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Oops, a little mistake in server's connection authentication
8186 protocol. The protocol is not ended with FAILURE but with
8187 SUCCESS if the authentication is Ok. :) Affected file is
8190 * Implemented NICK_CHANGE notify handling in server in the file
8191 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8192 the local clients on the channel. After the changing nickname
8193 in router environment snhould work and the [<unknown>] nickname
8194 should appear no more.
8196 The silc_server_replace_id function that receives the Replace ID
8197 payload now sends the NICK_CHANGE notify type also in the file
8198 silcd/packet_receive.c
8200 * Changed WHOIS and IDENTIFY command to support the maximum amount
8201 of arguments defined in protocol specs (3328 arguments). This
8202 fixed a bug that caused problems when there were more than three
8205 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8207 * Added extra parameter, command identifier, to the
8208 silc_client_send_command so that explicit command identifier
8211 Changed that ID list routines uses specific command identifier
8212 when sending WHOIS/IDENTIFY requests to the server so that they
8213 can be identified when the reply comes back.
8215 Affected files lib/silcclient/command.[ch],
8216 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8218 * Added `sender' argument to silc_server_packet_send_to_channel
8219 to indicaet the sender who originally sent the packet to us
8220 that we are now re-sending. Ignored if NULL. Affected file
8221 silcd/packet_send.[ch].
8223 * Added some server statistics support in silcd/server_internal.h
8224 SilcServerStatistics structure and around the server code. Also
8225 send some nice statistics information when client is connecting
8228 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8230 * Fixed channel ID decoding in server's JOIN command reply in
8231 silcd/command_reply.c
8233 * Fixed braodcasting of replace ID payload to not to send it if
8234 we are standalone server in silcd/packet_receive.c.
8236 * Fixed all channel message sending routines to not to send
8237 packets to clients that has router set, since they are routed
8238 separately in the same function earlier. Affects file
8239 silcd/packet_send.c and all channel packet sending functions.
8241 * In USERS reply, res_argv[i] are not allocated, the table
8242 is allocated. Thus changed that free the table, not its
8245 * In server's whois_check and identify_check if the client is
8246 locally connected do not send any WHOIS commands - they are not
8249 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8251 * Fixed some minor bugs in client when sending WHOIS command. The
8252 arguments was in wrong order.
8254 * Removed statis function add_to_channel from server in
8255 silcd/command.c that was previously used with the joining but
8258 * Tested USERS command in router environment successfully with two
8259 routers, two servers and two clients.
8261 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Reorganized the USERS command and command reply in client library
8264 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8265 When the command is given by user we register a pending command
8266 callback that will reprocess the command after the reply has been
8267 received from the server. When reprocessing the packet we then
8268 display the information. Thus, the USERS information is displayed
8269 now in the command callback instead of in the command reply
8270 callback. The processing of the command is same as previously
8271 when server has sent the command reply in the JOINing process.
8273 * Added to USERS command in silcd/command_reply.c to join the client,
8274 we didn't use to know about, to the channel after we've created
8275 a client entry for it. Also, for clienet we did know already still
8276 check whether it is on the channel or not and add it if not.
8278 * Removed silc_server_command_join_notify as the function and its
8281 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8283 * Changed the client's pending command handling to the same as the
8284 server's pending command handling. It is also now possible to
8285 execute command reply functions from other command reply
8286 function as the function callbacks for commands and command
8287 replies are one and same. The pending commands are not static
8288 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8289 in client connection context. Thus, pending commands are server
8290 connection specific as it is convenient.
8292 Changed the function silc_client_command_pending and
8293 silc_client_command_pending_del and added new function
8294 silc_client_command_pending_check. Removed the
8295 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8298 * Added cmd_ident, current command identifier, to the client
8299 connection context in lib/silcclient/client.h to keep track on
8300 command identifiers used in command sending. Client's command reply
8301 function handling now supports the mandatory command identifiers.
8303 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8304 funtions in client to fully support pending command callbacks.
8306 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8307 as one of the arguments to the application in the command reply
8310 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8311 before first releasing SILC but came back. Now it is removed again
8312 and should come back nomore. The FORWARDED flag was used only
8313 by the JOINing procedure by forwarding the command packet to router.
8314 Now, the JOINing procedure has been changed to more generic (due
8315 to various router environment issues) and FORWARDED is not needed
8316 anymore for anything. The protocol specification is yet to be
8319 Now, removed silc_server_packet_forward from server and the flag
8320 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8322 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8324 * Renamed NAMES command to USERS command. The NAMES was named that
8325 due to historical reasons. Now it is renamed. Also, rewrote
8326 parts of the USERS command. The nickname list is not sent anymore
8327 by the server. Only Client ID and mode lists are sent in the USERS
8328 command. Changed this also to the protocol specification.
8330 The client now resolves the names and stuff after it receives
8331 the USERS list from the server when joining to the channel.
8333 * WHOIS and IDENTIFY commands has been changed to support multiple
8334 Client ID's per command. One can now search for multiple users
8335 in the network by sending only one WHOIS or IDENTIFY command.
8336 Changed the code and the protocol specifications.
8338 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8339 uses silc_server_command_whois_parse to parse the request. */
8341 * If normal server, do not parse the WHOIS and IDENTIFY requests
8342 before sending it to the router. Saves some time.
8344 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8346 * Fixed JOIN command on client library. Wrong number of arguments
8347 used to crash the client.
8349 * Added silc_server_channel_has_global function to check whether
8350 channel has global users or not.
8352 * Added silc_server_channel_has_local function to check whether channel
8353 has locally connected clients on the channel.
8355 * The silc_server_remove_from_one_channel now checks whether the
8356 channel has global users or not after given client was removed from
8357 the channel. It also checks whether the channel has local clients
8358 on the channel anymore. If it does not have then the channel entry
8359 is removed as it is not needed anymore.
8361 * The silc_server_notify now checks on JOIN notify whether the joining
8362 client is one of locally connected or global. If it is global then
8363 the channel has now global users on the channel and that is marked
8364 to the channel entry. Also, it now saves the global client to
8365 global list who is joining and JOINs it to the channel. This is
8366 for normal server, that is.
8368 Changed silc_server_send_notify_on_channel,
8369 silc_server_packet_relay_to_channel and
8370 silc_server_packet_send_to_channel check if we are normal server
8371 and client has router set (ie. global client) do not send the
8372 message to that client, as it is already routed to our router.
8374 * Implemented LEAVE notify type handling in silc_server_notify
8377 * Tested LEAVE command in router environment successfully. Tested
8378 with two routers, two servers and two clients.
8382 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8384 * Implemented SIGNOFF notify type handling in silc_server_notify
8387 * silc_server_remove_id now removes the client entry from all channels
8388 it has joined and thusly sends SIGNOFF notify type.
8390 * Rewrote the NAMES list generation in server by removing two excess
8391 loops. The lists are created now inside one loop.
8393 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8395 * silc_server_remove_channel_user checks now also global list
8396 for channel and client.
8398 * silc_server_new_channel_user checks now both local and global
8399 list for channel and client. Fixed a bug in client id decoding.
8400 Used to decode wrong buffer.
8402 * silc_server_channel_message checks now both local and global
8403 list for channel entry.
8405 * Tested channel joining (hence JOIN) in router environment
8406 successfully. Tested with two routers, two servers and two
8409 * Tested channel message sending in router environment successfully.
8411 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8413 * Added silc_server_save_channel_key into server.[ch] to save the
8414 received channel key in Channel Key payload processing. It is
8415 also used in JOIN command reply handling.
8417 Equivalent function silc_client_save_channel_key added into
8418 client.[ch] into client library.
8420 * Changed JOIN command reply to send information whether the channel
8421 was created or not (is existing already) and the channel key
8422 payload. Changed protocol specs accordingly.
8424 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8425 the request was sent by ID and not by nickname. Crashed on
8428 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8430 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8431 now correctly save the received data.
8433 * silc_server_free_sock_user_data now notifies routers in the
8434 network about entities leaving the network.
8436 At the same time implemented functions silc_server_remove_id
8437 and silc_server_send_remove_id to receive and send REMOVE_ID
8438 packets. The packet is used to notify routers in the network
8439 about leaving entities. The ID removed will become invalid in
8442 * Added function silc_idlist_del_server into server. Removes and
8443 free's server entry from ID list.
8445 * silc_server_private_message function now checks, if we are router,
8446 that the destination ID really is valid ID, naturally.
8448 * In router when NEW_ID packet is received (for new client) the
8449 hash of the Client ID is saved in the ID Cache but the
8450 client->nickname is set to NULL, instead of putting the hash
8453 IDENTIFY command now also checks that client->nickname must be
8454 valid. If it is not if will request the data from the server who
8455 owns the client. Added new function
8456 silc_server_command_identify_check.
8458 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8459 to set the command to already allocated Command Payload.
8461 * Tested private message sending in router environment with two
8462 routers, two servers and two clients. Fixed minor bugs and now
8465 * Fixed segfault from client's NAMES command. Used to crash if
8468 * Forwarded packets must not be routed even if it is not destined
8469 to the receiver. Changed server code comply with this.
8471 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8473 * Added `require_reverse_mapping' boolean value to ServerParams
8474 structure. If TRUE (not default) the server will require that
8475 the connecting host has fully qualified domain name.
8477 If the reverse mapping is not required and hostname could not be
8478 found the IP address is used as hostname.
8480 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8482 * Implemented version string checking to both client and server.
8483 The check is incomplete currently due to the abnormal version
8484 strings used in development version of SILC.
8486 * Changed all command functions in server to use the new
8489 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8491 * Changed char *data to unsigned char *data in ID Cache system to
8492 support binary data as ID Cache data. Changed code to support
8493 binary data in lib/silccore/idcache.c.
8495 * Renamed silc_server_packet_relay_command_reply to
8496 silc_server_command_reply as it is normal packet receiving
8497 function. Rewrote the function to accept command replys for
8498 servers and not only for clients.
8500 * Mark remote router always as registered server if we are connecting
8501 to it. Otherwise, commands sent by the router to us are ignored.
8503 * All ID List find routines now returns the ID Cache Entry pointer
8504 as well if requested.
8506 * WHOIS command works now in router environment, tested with two
8507 routers, two servers and two clients.
8509 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8510 in router environment (as it is almost equivalent to WHOIS) but
8511 hasn't been tested thoroughly. Added new functions:
8513 silc_server_command_identify_parse
8514 silc_server_command_identify_send_reply
8515 silc_server_command_identify_from_client
8516 silc_server_command_identify_from_server
8518 * Disabled route cache adding because adding two different ID's with
8519 same IP replaces the old cache entry thus giving wrong route.
8520 The entry->router->connection is always the fastest route anyway
8521 so route cache may not be needed. Of course, new routes maybe
8522 established after receiving the ID when the entry->router->connection
8523 might not be anymore the most optimal.
8525 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8527 * Add route cache for received ID for fast routing.
8529 * Added silc_server_packet_route to route received packet on router
8530 that is not destined to us.
8532 * Renamed silc_server_get_route to silc_server_route_get.
8534 * Added id_string and id_string_len fields into SilcServer to
8535 include encoded ServerID for fast comparing without excess
8536 encoding of the ID's.
8538 * Cleaned up WHOIS command on server side. Added following static
8541 silc_server_command_whois_parse
8542 silc_server_command_whois_check
8543 silc_server_command_whois_send_reply
8544 silc_server_command_whois_from_client
8545 silc_server_command_whois_from_server
8547 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8548 arguments in command replies. All command functions should be
8549 updated to use this macro.
8551 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8553 * Minor typo fixes on command reply handling on server.
8555 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8557 * Added silc_server_command_add_to_channel internal routine to add
8558 the client to the channel after router has created the channel and
8559 sent command reply to the server.
8561 * Added generic silc_server_send_command to send any command from
8564 * Use static buffer with ID rendering instead of duplicating data.
8566 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8568 * Fixed a channel user mode bug when joining to a channel server gave
8569 everybody channel founder rights, oops.
8571 * We mark ourselves as the router of the incoming server connection
8572 if we are router ourselves. This way we can check in some packet
8573 sending functions whether it is locally connected server. For
8574 incoming router connections we put NULL.
8576 * For router sending packets locally means now always sending the
8577 packet cell wide; to local clients and local servers. For normal
8578 server sending packet locally means sending it to only local
8581 * Fixed the JOIN command to really work in router environment. If the
8582 channel is created it is always created by the router. Router is
8583 also responsible of making the initial joining to the channel,
8584 sending JOIN notify to the sending server and distributing
8585 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8586 does not exist server doesn't do anything else but forward the
8587 command to the router which performs everything.
8589 * Added silc_server_send_channel_key function to send the Channel Key
8592 * Added silc_server_create_channel_key to create new channel key. The
8593 channel key is now re-generated everytime someone joins or leaves
8594 a channel, as protocol dictates. Note: channel->key_len is the
8597 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8599 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8600 packet_receive.[ch] to separate packet sending and receiving
8601 routines. The server.[ch] now includes everything else including
8602 actual packet processing (writing and reading data) and other
8605 Renamed silc_server_private_message_send_internal to
8606 silc_server_send_private_message. The routine is still though
8607 used only to relay private messages as server does not send
8608 private messages itself.
8610 Renamed silc_server_new_channel to silc_server_create_new_channel
8611 and added new function sicl_server_new_channel that handles the
8612 incoming New Channel packet. Added also new sending function
8613 silc_server_send_new_channel to send New Channel Payload.
8615 * Added new function silc_server_notify to process incoming notify
8616 packet to the server/router. Server may then relay the notify
8617 to clients if needed.
8619 * Added new function silc_server_new_channel_user to process incoming
8620 New Channel User packet. Router will redistribute the packet and
8621 send JOIN notify to its local clients and locally connected servers
8622 if needed. Normal server will send JOIN notify to its local client
8623 on same channel when received this packet. Added also corresponding
8624 sending function silc_server_send_new_channel_user to sent the
8627 * Added boolean route argument to send_notif_to_channel and
8628 packet_send_to_channel functions to attempt to route the packet
8629 if it is TRUE and send only locally if it is FALSE.
8631 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8633 * silc_server_replace_id now broadcasts the received replace ID
8634 packet if it is not broadcast packet already. The router must
8635 broadcast to inform other routers about changed ID.
8637 * Added backpointer to server's router into SilcServer context in
8638 silcd/server_internal.h.
8640 * Fixed silc_server_packet_broadcast to send correct broadcast
8643 * The channel key is now distributed to the local client as soon
8644 as it is received from the router (in router environment) so that
8645 no other packet may be sent for the channel until client has
8648 * silc_server_remove_channel_user now broadcasts the received
8649 Remove Channel User packet if it is not broadcast packet already.
8650 The router must broadcast to inform other routers about removed
8653 * Added users field into SilcPacketContext that is a reference count
8654 of the context. One can increase the reference count by calling
8655 silc_packet_context_dup which is now changed to just increase the
8656 reference count instead of duplicating the data. The reference
8657 count is decresed by calling silc_packet_context_free that will
8658 free the data after the reference count hits zero.
8660 For now on the packet context and everything allocated into it
8661 (including the raw packet from network) must be freed by calling
8662 the new silc_packet_context_free function. Added also new function
8663 silc_packet_context_alloc that must be used now to allocate the
8664 context. This also means that if a routine is asynchronous from
8665 silc_[client/server]_packet_parse_type the packet context must
8666 be duplicated by calling silc_packet_context_dup. Otherwise it
8667 gets free'd after silc_[client/server]_packet_parse_type returns.
8668 Also, one must remember that if packet is duplicated then its
8669 reference count must be decresed by calling the free function as
8670 many times as it was duplicated.
8672 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8673 from both client and server.
8675 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8677 * Made joining to a channel working in router environment.
8679 * Cleaned up JOIN command on server side and create function
8680 silc_server_command_join_channel internal routine to make the
8683 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8685 * Changed silc_command_pending list to SilcDList. Also, added
8686 `ident' field to SilcServerCommandPending structure to identify
8687 the reply and to call correct callback.
8689 Added silc_server_command_pending_check function to replace the
8690 corresnponding macro. The silc_command_pending list is not
8693 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8694 to set identifier to previously allocated Command Payload. It
8695 is used to set identifier for command when resending Command
8698 * Added silc_command_payload_encode_payload to encode Command
8699 Payload buffer from SilcCommandPayload structure.
8701 * Added silc_argument_payload_encode_payload to encode Argument
8702 payload buffer from SilcArgumentPayload structure.
8704 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8706 * Changed WHOIS command to support router connection on server side.
8707 The whois request is always sent to router unless the server is
8708 standalone server. After server has received the reply from the
8709 router will it send the reply to the client.
8711 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8712 broadcast received broadcast packet. The function is used only
8713 by router. The broadcast packet is always sent to the router's
8716 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8717 render given ID to printable string, for log files for example.
8719 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8721 * Made basic router to router connections working. At least they
8722 can now connect to each other but nothing really works the way
8723 they are supposed - yet.
8725 * Added new initiator token to RouterConnection configuration
8726 file in silcd/serverconfig.[ch]. It is used to tell whether we
8727 are the initiator to the remote router or whether we'll expect
8728 the other end to connect.
8730 * Moved registering of listener task to silc_server_init, hence
8731 the server starts listenning as soon as it is run, even if it
8732 does not have connections to other routers. Let's see how well
8735 * Changed default connection retry timeouts for more suitable in
8738 * Removed cipher and such arguments from silc_idlist_add_client
8739 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8740 Added new function silc_idlist_add_data to add the keys and stuff
8743 * Added SilcIDListData structure and added it to SilcClientEntry
8744 and SilcServerEntry as their first field in the structure. This
8745 way we can explicitly cast the ID entries to the SilcIDListData
8746 structure and get common data for the entries. In past, we had
8747 to first check what type of connection it is and then cast it to
8748 correct ID entry type. Now, we can directly cast the opaque
8749 pointer to the SilcIDListData (no matter what ID entry it actually
8750 is) and get the data needed.
8752 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8754 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8755 in some circumstances even if threre were timeout tasks, though not
8756 IO tasks, but tasks anyway. Now fixed.
8758 * Defined SilcServerConnection structure to hold connection specific
8759 stuff about directly connected servers and routers. The definition
8760 is currently in silcd/server_internal.h. I thought about having
8761 a bit more important role fro this struct but for now it is used
8762 only when connecting to other server (or router actually).
8764 * Added connecting retry support in server when connecting to
8765 router(s). The retry feature implement exponential backoff
8766 algorithm. Also, added SilcServerParams structure to hold default
8767 parameters for server. For now, it include these retry settings
8768 and are hard coded. After server is moded to be as Silc Server
8769 Library this structure will be more important.
8771 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8773 * Changed client librarys channel->clients table to SilcList and
8774 changed code accordingly.
8776 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8778 * Changed client's channel table to SilcList and changed code
8779 accordingly. Also changed SilcChannelClientEntry to include back-
8780 pointer to the channel so that client entry can use that structure
8781 as list as well and we have fast cross-reference to the channel.
8782 This change dramatically decreased the complexity of channel
8783 handling with client entry and vice versa (removed one extra
8784 loop when searching for channel entry from many functions).
8786 * Changed server->sim from table to SilcDList and changed code
8789 * NAMES command can now be used from user interface. It will show
8790 the user list on the channel, neatly.
8792 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8793 Code now saves realname of the user if it becomes available.
8795 * Renamed configure.in to configure.in.pre and made ./prepare
8796 script to automatically add correct version string to
8797 configure.in which it creates from configure.in.pre.
8799 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8801 * NAMES command reply now shows users mode with the nickname when
8804 * Moved silc_client_ch[u]mode[_char] functions from
8805 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8806 place sucks, they are utility functions and should be in some
8809 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8811 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8814 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8818 * Added TRQ (efficient deque and list library) into lib/trq. This is
8819 a very good list library that is currently used in the SILC. Defined
8820 SilcList API over the library because I didn't like the API very
8821 much. See lib/trq/silclist.h for the API and examples of how to
8822 use the API. Fixed various places in the code to use the new
8823 SilcList API. The SilcList is meant for lists that has a structure
8824 already defined as a list. It is not suitable to add just some
8825 context to the list (in TRQ, the context is the list actually).
8827 So, I defined SilcDList that can be used for the purpose where
8828 predefined list structure does not exit. This can be used as
8829 such list. Now some context just can be added to the SilcDList.
8830 Currently this list is not used in the SILC just yet, though there
8831 are a lot places where this can replace dynamically allocated
8832 tables and I will fix these places, later, to use SilcDList.
8833 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8834 and use TRQ internally).
8836 Also fixed some annoying warning messages that the original TRQ
8837 code generated. Also minor changes to TRQ's Makefile.in.
8839 * Added support for querying by Client ID to both WHOIS and
8840 IDENTIFY commands into server, as required by the protocol.
8842 * Removed method function pointers from SilcBuffer structure. They
8843 weren't used to anything and just increased the context size for
8844 no good reason. This change also made silc_buffer_alloc and
8845 silc_buffer_free functions inline functions.
8847 * Disabled command flooding detection support until it's fixed so
8848 that it accepts commands in but does not execute them more than once
8851 * Added silc_net_localhost(), to return local hostname, into
8852 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8853 that must be initialized before calling silc_client_init.
8855 * Added new function: silc_server_send_notify_on_channels to send
8856 notify messages to all channels client has joined. It is assured
8857 that the message is sent only once per client.
8859 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8860 lib/silcutil/silcutil.[ch] as silc_format function. The new
8861 function is generic and is used by server as well, not only by
8862 the logging routines.
8864 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8865 the provided version string was not acceptable. Added new function:
8866 silc_ske_check_version into lib/silcske/silcske.h. The function
8867 must be implemented by the application (client or server) and it
8868 does not reside in the SKE library. The function checks the version
8869 string remote end sent.
8871 * Added back pointers (to opaque context and to SilcSocketConnection)
8872 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8874 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8875 duplicate packet context structure.
8877 * Changed `notify' client operation to send same arguments as client
8878 receives from server except for ID's. ID's are mapped to correct
8879 ID entry and that is returned. Also, if channel entry is not sent
8880 by server but the notify is for channel the channel entry is sent
8881 to application (otherwise application doesn't know that it is for
8882 channel (library gets it from packet's Destination ID)).
8884 * Added silc_client_remove_from_channels into client library to
8885 remove a client from all channels it has joined to. Used when
8886 received SIGNOFF notify from server. Added also new function
8887 silc_client_replace_from_channels to replace old ID entry with
8888 new ID entry on all channels. Used when received NICK_CHANGE
8891 * Fixed ID Cache list handling in silc_idlist_get_client in
8892 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8893 to get (or query) client by ID.
8895 * Updated TODO list.
8897 * Added connection authentication status message defined by the
8898 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8899 support for these into the code in client and server side.
8901 * Added generic function silc_client_send_command to send any command
8902 with variable argument list. Application should use this function
8903 to send commands if the command functions provided by the library
8904 does not suite for the application's user interface needs.
8906 * Added new `failure' client operation. Application is notified about
8907 received failure packet if client is executing a protocol. In this
8908 case the protocol's execution has failed.
8910 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8911 is required by the protocol.
8913 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8914 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8917 * Added status flag to SilcSKE object to indicate realtime status
8918 of the SKE protocol.
8920 * Application receives now exactly same command reply arguments as
8921 the library receives from server. However, if ID is received the
8922 corresponding ID entry is returned to the application (eg. Client
8923 ID is mapped to correct SilcClientEntry entry and that is returned).
8924 Changed command_reply client operation due to this change.
8926 * Changed all ID's in commands and in command replys as ID Payloads.
8927 Change affected both client and server side codes.
8929 All ID's sent in SILC network (with execption of ID's in SILC
8930 Packet header) are sent in ID Payload to support variable length
8933 * Server now notifies nick changes and notifies all clients on
8934 the channels about the new nickname (about the new Client ID,
8937 * Implemented CMODE command to change channel modes. Supports all
8938 channel modes defined by the protocol specs except ban and invite
8939 lists. (Also, private channel key mode is supported but support for
8940 setting private channel key in client is missing, thus, this mode
8941 has no effect on client side (except that server requires that the
8942 client uses private channel key and normal channel traffic does not
8945 Also, invite mode works per se, but INVITE command does not work
8946 yet correctly, so you can set channel as invite only channel but
8947 inviting clients to the channel does not work (it is yet to be
8948 thought what's the best way to do it).
8950 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8951 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8952 Implemented CUMODE command to change user's mode on the channel.
8953 Supports all modes defined by the protocol specs.
8955 * Added NAMES command reply to return users modes on the channel.
8957 * Removed unnecessary and slow ciphers from lib/silccrypt.
8959 * Set SO_KEEPALIVE option to connection sockets by default.
8961 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8963 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8964 redefined the Notify Payload into protocol specs.
8966 * Added silc_id_payload_parse_id to get ID directly from raw
8969 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8971 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8972 accept searching by Client ID as well.
8974 * Added support for LEAVE and SIGNOFF notify types in client library.
8976 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8977 to parse ID Payload from raw data.
8979 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8981 * Added flags parameter into silc_ske_assemble_security_properties
8982 function in lib/silcske/silcske.[ch].
8984 * Changed notify client operation to fit better for notify messages
8985 sent by server. The notify payload received from server is now
8986 passed to the application (after parsing it to SilcNotifyPayload).
8987 It is application's responsibility to retrieve the arguments
8988 from the payload and show the message the way it wants. The message
8989 sent by server is implementation specific.
8991 * Changed public keys to comply with the protocol specification.
8992 Old public keys are not supported anymore and are not compatible.
8994 * Removed nickname from Channel Payload as the latest draft removed
8995 it. The client must resolve the nickname from the NAMES command
8996 reply received when it joined the channel.
8998 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9000 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9002 * Fixed some errors in protocol specification drafts.
9004 * Created lib/silccore/silcnotify.c to implement Notify Payload
9005 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9006 generic payloads described by protocol specifications. The file
9007 includes implementations for ID Payload and Argument Payload.
9009 * Changed Command Payload implementation to use the new Argument
9010 Payload. Changed command_xxxx_payload to command_payload_xxxx
9011 to comply with SILC coding conventions.
9013 * Added suppport for Argument Payload handling in Notify Payload
9014 implementation as protocol requires it. Added the new support
9015 into server and client lib as well.
9017 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9019 * Added support for multiple nicknames on same channel. [n] is
9020 added locally to the nickname if there are more than one same
9021 nicknames on the channel.
9023 * Server now sends all nicknames that matched WHOIS request.
9024 Client also shows the list received from server.
9026 * Added TOPIC command to client side. User can now set and show
9027 current topic on channel.
9029 * Added MOTD command to client and server. Also, server sends the
9030 motd when client connects to the server.
9032 * Changed version strings to comply ISO 8601.
9034 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9036 * Fixed protocol error handling in client library. It should now
9037 cope even if the SKE fails for some reason.
9039 * Made new protocol specification drafts for submitting to IETF.
9041 * Implemented TOPIC command to server in silcd/command.c.
9043 * Added two new notify types into lib/silccore/silcnotify.h:
9044 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9045 notify nickname change and topic setting/change on a channel.
9047 * API change of command_reply operation in client library. The
9048 application gets now the status type received from server as well.
9050 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9052 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9054 * Cras fixed and optimized the packet handling even further and
9055 it should work now. Minor change to the prototype of function
9056 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9058 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9060 * Added new function into lib/silcutil/silcschedule.[ch]:
9061 silc_schedule_with_fd to select() a specified fd. The function
9062 returns after timeout expires or data arrives or goes. The
9063 function is used by packet routines to wait that all data is
9064 received from network.
9066 * Fixed data reading from network in lib/silccore/silcpacket.c.
9067 The code now assures that all data is read from the fd and then
9068 continues packet processing. This was a bug fix since the code
9069 used to drop some data in some circumstances.
9071 * Added new function into lib/silcclient/client.[ch]:
9072 silc_client_start_key_exchange to start key exchange after
9073 connection has been established to server. The code internally
9074 now uses this funtion but its main purpose was to provide it
9075 for applications that perform their own connecting. After
9076 application has created a connection it merely calls this
9077 function to start the key exchange between client and server.
9078 The library takes care of everything else after that.
9080 Updated also lib/silcclient/README to explain the usage of
9083 * Do not send to application information that connection has
9084 been established. Application gets notified it by connect
9087 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9089 * Applied cras's patch to add silc_schedule_one function. The
9090 function runs scheduler once and returns.
9092 * Fixed the scheduler after cras messed it up. The timeout
9093 handling works now as it's supposed to work.
9095 * Added into lib/silccore/ silcnotify.h to include notify
9096 message types support. Changed silc_server_send_notify*
9097 functions, in server.[ch], to support those new notify types.
9098 Added the support for the notify types into client library,
9099 as well. Added new notify client operation into ops.h in
9102 * Changed silc_server_packet_send_to_channel to send normal
9103 packets instead of just channel message packets. The function
9104 is now used to send the notify packets to channels. It is not
9105 used to send channel message packets anymore, as server never
9108 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9109 va_arg()s as it seems to require it nowadays. I guess, if SILC
9110 is compiled with older va_arg() the new code should work anyway.
9112 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9114 * Splitted core library. Core library (lib/silccore) includes
9115 now only SILC protocol specific core (and common) components.
9116 Created new utility library (lib/silcutil) that includes more
9117 generic purpose stuff. The stuff for util library was taken
9118 from the old core library. This was minor and easy split.
9120 * Created SILC Client Library (lib/silcclient) that includes
9121 implementation of the SILC client without user interface. This
9122 was major move from silc/ directory. The code has been changed
9123 so that it is transparent towards the user interface. The
9124 silc/ directory includes now the same user interface as before
9125 and it uses the new client library. Read lib/silcclient/README.
9126 Basicly, the client library performs everything else related
9127 to SILC except user interface handling. Also, configuration
9128 files are considered to be part of user interface and library
9129 does not handle them.
9131 This change also changed a lot of structures, function naming etc.
9132 Most important change was that SilcClientWindow object was
9133 renamed to SilcClientConnection in the client library. Created
9134 also new file lib/silcclient/ops.h. Also added new files
9135 silc/local_command.[ch] and silc/client_ops.[ch].
9137 All these changes were made to make it easier for user interface
9138 designers to create what ever user interface for the SILC client
9141 It is also expected that the server will be moved to lib
9142 directory as well and SILC Server Library will be created;
9143 sometimes in the future.
9145 * Removed Local commands from lib/silccore/silccommand.h as
9146 they are application specific and new client library does not
9147 handle any of those anymore.
9149 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9150 old client implementation in silc/.
9152 * Added support for callback functions in SILC_LOG_* macros.
9153 Application can now set its own callbacks that will be called
9154 instead of using the default functions that will always print
9155 the debug messages to stderr (or stdout). Also, debugging can
9156 now be disabled by setting silc_debug to FALSE and re-enabled by
9157 setting it to TRUE. Note, that logging will still work even
9158 if debugging is disabled.
9160 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9161 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9162 silc_log_reset_debug_callbacks.
9164 * To enable debugging in silc client one must give now -d
9165 option on command line.
9167 * Changed silc_schedule_init to automatically allocate task queues
9168 if they are not allocated before calling it.
9170 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9172 * Added GMP 3.1 into math library.
9174 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9176 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9177 a channel in SILC network. The packet is used by servers and
9178 routers to notify other routers that user has left a channel.
9179 This little feature was missing until now. Added the feature
9180 to protocol specification as well.
9182 Added functions: silc_server_send_remove_channel_user and
9183 silc_server_remove_channel_user into server.[ch].
9185 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9186 lib/silccore/silcpacket.h. However, they are not implemented
9189 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9191 * Fixed joining to a channel and sending channel messages
9192 between server and router. The channel message sending should
9193 now work inside a cell.
9195 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9197 * Fixed the private message sending between server and router.
9198 The private message sending should now work inside a cell.
9200 * Added silc_server_replace_id into server.[ch] to replace
9201 existing ID in the SILC network.
9203 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9204 and silc_idlist_replace_server_id into idlist.[ch] in server.
9206 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9208 * Fixed the server to server connections. Server can again now
9209 connect to router. Router to router connections probably does
9212 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9214 * Added dynamic protocol registering support. Now protocols can
9215 registered and unregistered on the fly. Patch by cras.
9217 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9219 * Added lib/contrib directory to hold routines that some platforms
9220 don't have but are needed by SILC.
9222 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9223 into lin/contrib to provide getopt() and getopt_long() for
9224 those who don't have it.
9226 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9228 * Added AWAY command to client. When away message is set and
9229 client receives a private message packet the client automatically
9230 replies to the sender with the away message.
9232 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9233 bug seemed to be the cause of recent problems when compiling
9236 * Added version detection support to SKE protocol specification
9237 and added the new changes to the SKE implementation as well.
9238 There were other minor changes in the SKE protocol as well.
9240 Many changes in lib/silcske/silcske.[ch] and in
9241 lib/silcske/payload.[ch].
9243 * Added ^U functionality, clear input line. Patch from cras.
9245 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9247 * Mainly small bugfixes on core library. Fixed some debugging
9248 logging and buffer overflow in silclog.c.
9250 * Updated config.sub and config.guess on the distribution tree.
9252 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9254 * Added command lagging support in server. Client may execute
9255 commands now only once in two seconds.
9257 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9259 * Optimized packet reception. MAC computation and checking is now
9260 also more optimized. A lot previously duplicated code is now
9261 used as generic by both client and server.
9263 * Fixed key pair generation in clientutil.c
9265 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9267 * Added into lib/silccore/silcbufutil.[ch] new function;
9268 silc_buffer_realloc.
9270 * Moved generic packet sending/encryption functions to
9271 lib/silccore/silcpacket.[ch] from client and server. Some
9272 rewriting of the functions.
9274 * Moved all generic packet reception/decryption functions to
9275 lib/silccore/silcpacket.[ch] from client and server. The
9276 packet processing is now much cleaner in both client and server.
9277 These were major changes in both client and server.
9279 * Created many common functions in server to do packet sending.
9280 Previously code were duplicated a lot, this has been removed
9283 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9285 * Rewrote major parts of the ID cache system. Don't know
9286 whether it is better now or not but at least the API is more
9289 * Major rewrite on ID cache stuff on client because of the ID
9290 cache API changes. Added idlist.c to client.
9292 * Also major rewrite on ID cache stuff on server as well.
9293 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9294 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9295 in hand, instead they are all put into the ID cache system now.
9296 All server_idlist_* routines uses ID cache now instead of
9297 traversing its own lists (those lists does not exist anymore).
9298 SilcIDList though still exists. Also, SilcXXXEntry's are
9301 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9303 * Finally made the SKE implementation compliant to the protocol
9304 specification. All mp integers are now binary encoded as
9305 opposed being HEX encoded.
9307 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9310 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9311 functions: silc_[encode/decode]_pem. Also added function
9312 silc_encode_pem_file to PEM encode with newlines ('\n') for
9315 * SILC public keys are now encoded either PEM or binary. Same
9316 option is for private keys as well. By default private keys
9317 are binary encoded and public keys PEM encoded. Silly HEX
9318 encoding were removed.
9320 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9321 function to create fingerprints.
9323 * Fixed a bug in SHA1; does not change the original data anymore.
9325 * Partly implemented INFO command on client and server side.
9326 Fixed CLEAR command. Changes to SERVER command; show current
9327 server(s) when giving command without arguments. Added
9328 VERSION command to client.
9330 * Added check to server that unregistered connections cannot
9331 execute commands (unless it is specificly allowed).
9333 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9335 * Fixed screen refresh.
9337 * Fixed channel joining bug from client. On some circumstances
9338 client tried to join to a channel it had already joined.
9340 * Added public key verification process into client's protocol.c.
9341 The client now verifies the public key from user and saves
9342 it into ~./silc/serverkeys/ directory.
9344 Added into: clientutil.[ch]: silc_client_verify_server_key.
9346 * Changed SKE protocol's silc_ske_initiator_finish function
9347 to accept callback function that verifies the received public
9348 key. Removed old silc_ske_verify_public_key function.
9350 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9352 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9353 silc_pkcs_private_key[_data]_set.
9355 * Made the password and public authentication more cleaner in
9356 server's protocol.c.
9358 * Removed historic and obsolete protocol `channel_auth' from
9359 both client and server.
9361 * Removed wrong way of sending command status messages from
9362 server to client in server's command.c. The old way violated
9363 protocol specification.
9365 Changes to silccore/silccommand.[ch]: removed
9366 silc_command_encode_status_payload -> not needed anymore,
9367 changed silc_command_encode_payload_va to accept extra
9368 argument on variable argument list. The argument type must
9369 now be provided to the function. Also, added new function:
9370 silc_command_encode_reply_payload_va which is same as
9371 normal command_encode_payload_va except command status type
9372 is provided as extra argument.
9374 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9376 * Added ~./silc directory handling. The directory includes the
9377 public and private keys for the client.
9379 Added silc_client_check_silc_dir, silc_client_create_identifier
9380 and silc_client_load_keys.
9382 * Implemented SILC protocol compliant public key. Added public
9383 and private key saving to and loading from files.
9385 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9386 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9387 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9388 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9389 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9391 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9392 silc_pkcs_load_[public/private]_key.
9394 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9396 * Added silc_server_get_route (route.[ch]) to get connection
9397 data for the fastest route for given ID.
9399 * Implemented INVITE command on client and server. The command
9400 were re-defined in the SILC Protocol Specification and the
9401 implementation now complies with the specification.
9403 * Implemented PING command on client and server.
9405 * Implemented NAMES command on client and server. The server side
9406 supports currently only normal server not router server yet.
9407 Some changes to NAMES definition in SILC protocol specification.
9409 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9411 * Implemented LEAVE command on client and server.
9413 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9414 again. This change was made to the protocol as well. Server
9415 should not violate the protocol specification anymore.
9417 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9419 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9420 was tested. SOCKS4 was not but should work anyway.
