77 Affected files silcd/serverconfig.[c], server.[c].
79 * Splitted the doc/example_silcd.conf.in. Separated the crypto
80 algorithm parts and created new file silcalgs.conf, that
81 is now included from the example_silcd.conf.in.
83 * Optimized the silc_server_connect_to_router_second to take
84 the connection configuration object from the SilcServerConnection

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

167 hash algorithm. Affected file lib/silccrypt/silcrng.c.
169 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
171 * Fixed the file transfer's key agreement payload to include
172 zero port also if the hostname is NULL because it could not
175 Call file transfer monitor callback now also if error occurs
176 during key agreement protocol.
178 Changed the silc_client_file_send interface to return the
179 SilcClientFileError instead of session id. The session ID
180 is returned into pointer provided as argument.
182 Check that the file exists locally before sending the
183 file transfer request at all.
185 Affected file lib/silcclient/client_ftp.c, silcapi.h.

197 file lib/silcutil/silclog.c.
199 * Fixed the channel message payload decryption in the function
200 silc_channel_message_payload_decrypt to not modify the original
201 buffer before it is verified that the message decrypted
202 correctly. Otherwise, next time it is called with correct
203 channel key it won't encrypt since the payload is corrupted.
204 Affected file lib/silccore/silcchannel.c.
206 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

219 the table with foreach callback. The current entry may
220 become invalid in the callback but it was referenced after
221 the callback returned.
223 Do not allow auto rehashing of hash table during the
224 silc_hash_table_foreach operation, for same reasons as it is
225 not allowed for SilcHashTableList. Affected files are
226 lib/silcutil/silchashtable.[ch].
228 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
230 * Defined DLLAPI into silcincludes.h and silcwin32.h for

234 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
236 * Fixed private message handling. It used some old code that
237 caused the client to crash. Affecte file is
238 lib/silcclient/client_prvmsg.c.
240 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
242 * Added function silc_client_add_channel,
243 silc_client_replace_channel_id, and removed functions
244 silc_client_new_channel_id and silc_idlist_get_channel_by_id
247 * Added cross reference of the joined channels to the
248 SilcClientEntry, and changed the SilcChannelEntry's
249 users list to SilcHashTable. The affected files are
250 lib/silcclient/idlist.[ch].
252 * Fixed a bug in hash table tarversing. While the hash table
253 is traversed with SilcHashTableList the table must not be
254 rehashed. It is now guaranteed that auto rehashable tables
255 are not rehashed while tarversing the list. Also defined that
256 silc_hash_table_rehash must not be called while tarversing
257 the table. Added function silc_hash_table_list_reset that must
258 be called after the tarversing is over. The affected files are
259 lib/silcutil/silchashtable.[ch].
261 * Changed all hash table traversing to call the new
262 silc_hash_table_list_reset in server and in client library.
264 * Added function silc_client_on_channel to return the
265 SilcChannelUser entry if the specified client entry is joined
266 on the specified channel. This is exported to application as
267 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
269 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
271 * Fixed founder regaining problem with JOIN command on normal
272 server. The notify for mode change must be sent always and
273 not only if !cmd->pending. Affected file silcd/command.c.
275 * Fixed the WHOWAS command's reply sending to support the
276 lists correctly. Affected file silcd/command.c.
278 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
280 * When sending JOIN command to router for processing the
281 sender's old command identifier was not saved back to the
282 sender's command context, fixed now. The affected file is
285 * Create the key in JOIN command of the router did not return
286 the channel key, added check for this. Affected file is
289 * Fixed a channel ID update bug in JOIN command reply. Do
290 not directly upgrade the ID but call the function
291 silc_idlist_replace_channel_id if the ID was changed.
292 Affected file silcd/command_reply.c.
294 * Fixed memory leaks from command calling if it would fail.
295 Affected file silcd/command.c.

302 new silclist.h and silcdlist.h, all extern inline changed to
305 * Removed dotconf from lib/dotconf, not needed anymore.
307 * Removed TRQ from lib/trq, not needed anymore.
309 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
310 with server connections. Later this will be configurable
311 in config file after new config file is done. Affected file
314 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
316 * Fixed a crash in server related to channel announcements.
317 Affected file silcd/server.c.
319 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
321 * Fixed memory leaks in silc_server_create_new_channel*
322 functions. Affected file silcd/server.c.
324 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
325 which ID was changed. This way the router will send the
326 user list for the channel again, and server won't be in
327 desync in some rare circumstances. Affected file is
328 silcd/packet_receive.c.
330 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
332 * Check for NULL socket pointer in the function

341 * Fixed some header addition to Toolkit distribution in
342 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
344 * Added lib/silcclient/client_ops_example.h as an template
345 file for application programmers to quickly start using
346 the SilcClientOperation functions in their application.
347 Updated the lib/silcclient/README as well to tell about this
348 nice file made available.
350 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
352 * Call silc_server_remove_from_channels when removing client
353 entry when NO_SUCH_CLIENT_ID was received. Affected file
354 is silcd/command_reply.c.
356 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
358 * Added server & router operator statistics updating. Affected
359 file silcd/packet_receive.c and silcd/command.c.
361 * Fixed the SERVER_SIGNOFF notify handling on normal server
362 not to save the history information for clients. Same was
363 fixed earlier in remove_clients_by_server function, but not
364 here. Affected file silcd/packet_receive.c.
366 * Raised the default connection-retry count from 4 to 7 in
367 server. Affected file silcd/server.h.
369 * Cancel any possible reconnect timeouts when we start the
370 key exchange. Affected file silcd/server.c.
372 * Do not reconnect on connection failure when SCONNECT was
373 given. Affected files silcd/server.[ch].
375 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
377 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
379 * Fixed the NICK command to always give the unformatted
380 nickname to the one giving the NICK command. If unformatted
381 nickname is cached already it will be formatted and the
382 local entry will always get the unformatted nickname.
383 Affected file lib/silcclient/idlist.c.
385 * Fixed some double frees from client library commands.
386 Affected file is lib/silcclient/command.c.
388 * Fixed CUMODE command in server to assure that no one can
389 change founder's mode than the founder itself, there was a
390 little bug. Affected file silcd/command.c.
392 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
394 * Removed the SilcClientCommandDestructor from the client
395 libary, it is not needed anymore. Affected files are
396 lib/silcclient/silcapi.h, command[_reply].[ch],
397 client_notify, idlist.c.
399 * Fixed GETKEY command to first resolve client, and then
400 resolve the server only if the client was not found, instead
401 of resolving both at the same time. Affected file is
402 lib/silcclient/command.c.
404 * Added silc_client_start_key_exchange_cb and lookup the
405 remote hostname and IP address before starting the key
406 exchange with server. The affected file is
407 lib/silcclient/client.c.
409 * The server's public key is now saved using the IP address
410 of the server and not the servername for the filename.
411 The hostname public key filename is checked as an fall back
412 method if the IP address based filename is not found.
414 Fixed the GETKEY command to save the fetched server key
417 Print the remote server's hostname now when new key is
418 received during connection process. Affected file is
419 irssi/src/silc/core/client_ops.c.
421 * Return always our own public key to the client if it asks
422 for it with GETKEY command. Affected file silcd/command.c.
424 * Removed the use_auto_addr variable from default config
425 file since it was in wrong section. Affected file is
428 * Fixed TOPIC_CHANGE notification to not route it when it
429 was sent using silc_server_send_notify_to_channel function.
430 Affected file silcd/command.c.
432 * Fixed silc_server_send_notify_kicked to send the kicker's
433 Client ID also, it was missing. Affected files are
434 silcd/command.c, silcd/packet_send.[ch].
436 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
438 * Do not save client history information in SERVER_SIGNOFF.
439 Fixes the bug in normal server that it does not detect
440 the client becoming valid after the server becomes back
441 online. Affected file silcd/server_util.c.
443 * Added `sock_error' field into the SilcSocketConnection
444 context. When error occurs during socket operation (read
445 or write) the error is saved. Added also new function
446 silc_socket_get_error to return human readable socket error
447 message. Affected files are lib/silcutil/silcsockconn.[ch],
448 lib/silcutil/unix/silcunixsockconn.c, and
449 lib/silcutil/win32/silcwin32sockconn.c.
451 * The server now prints the socket error message in the
452 signoff for client. Affected file silcd/server.c.
454 * Fixed the `created' channel information sending from router
455 to server in JOIN command. Checks now whether the channel
456 really was created or not and set it according that.
458 Fixed the JOIN command to use the client entry's current
459 ID during the joining procedure instead of the one it sent
460 in the command (it is checked though), since it can change
461 between the packet processing and command processing, and
462 would just case unnecessary pain in the client end. Affected
463 file silcd/command.c.
465 * Fixed a channel key payload sending to use correct channel
466 ID when the server was forced to change the channel's ID by
467 router. Router sent the key payload with the old Channel ID.
468 Affected file silcd/packet_receive.c.
470 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
472 * Call silc_server_save_channel_key only if the key payload
473 was provided in the JOIN command's command reply. Affected
474 file silcd/command_reply.c.
476 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
478 * Fixed silc_mp_sizeinbase to return the value correctly with
479 MPI. Affected file lib/silcmath/mp_mpi.c.
481 * Fixed the stop_server signal to correctly stop the scheduler
482 and gracefully stop the server when SIGTERM or SIGINT signals
483 are received. Affected file silcd/silcd.c.
485 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
487 * Simple handling of TERM and HUP signals. Also added some log
488 flushing call around. Affected file is
491 * Fixed small bugs in silclog.c. Now buffering output will take
492 effect after 10 seconds since startup: This will ensure that
493 no important startup messages are lost. Also output redirection
494 will preserve original format ([Date] [Type] message).
495 Affected file is lib/silcutil/silclog.c.
497 * Added two options to the config file, in the logging section:
498 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
499 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
501 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Do not print the warning about log files not being initialized
504 more than once to avoid excess logging. Affected file is
505 lib/silcutil/silclog.c.
507 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
508 the SIM copying in make install in Makefile.am.pre.
510 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
512 * Rewritten silclog APIs. Globally interesting changes follows:
513 silc_log_set_files() changed to silc_log_set_file().
514 silc_log_set_callbacks() changed to silc_log_set_callback().
515 ROBOdoc documented silclog header file.
516 SilcLogCb now returns bool to wether inihibit the default
517 handler or not (to keep the old behaviour return always TRUE).
518 The new APIs should also fix the problem of the
519 silcd_error.log file that was written in the current directory.
522 Log files streams will remain opened after silc_log_set_file()
523 call, means less CPU usage notably on high traffic servers.
524 File streams are now full buffered, and flushed to the disk
525 every 5 minutes, lesses HD activity and CPU usage.
526 Messages can be redirected, allowing admins to configure
527 one single logfile for all server messages.
528 the silc_log_quick global variable to activate fast-logging.
529 Affected files lib/silcutil/silclog.[ch]
531 * Changed some code to conform new silclog APIs. Affected
532 files are doc/example_silcd.conf.in, silcd/server.c
533 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
536 * Fixed a memory leak that could occur in some situations.
537 Affected file silcd/serverconfig.c.
539 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Added the silc_client_del_client to remove the client from
542 all channels as well. Affected file lib/silcclient/idlist.c.
544 * Fixed the client library to correctly remove the client
545 from all channels when the client entry is being destroyed.
546 Affected file lib/silcclient/client_notify.c, command.c.
548 * Added auto-nicking support to the client library. If the
549 applicatio now sets client->nickname it will be sent to the
550 server after connecting by the library. This way for example
551 SILCNICK (or IRCNICK) environment variables will have effect
552 and always change the nickname automatically to whatever
553 it is wanted. Affected file lib/silcclient/client.[ch].
555 * Renamed silc_server_command_bad_chars to the
556 silc_server_name_bad_chars and moved it to the
557 silcd/server_util.[ch]. Added also new function
558 silc_server_name_modify_bad to return nickname that
559 includes bad characters as new nickname without those
560 bad characters. This check and modify is now used in
561 silc_server_new_client when the username is initially set
562 as nickname, so it must be checked to be valid nickname.
563 Affected file silcd/packet_receive.c.
565 * The nickname length is now taken from the packet for real
566 and not trusted to strlen() since it clearly can return
567 wrong length for nickname including bad characters. This
568 also applies to channel names. Affected file silcd/command.c.
570 * Removed the lib/silcsilm/modules directory. Modules are now
571 compiled into the lib/silcsim. Fixed the copying of the
572 modules to follow symbolic links in Makefile.am.pre.
574 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
576 * Fixed silc_string_regexify list creation. Fixes bugs with
577 BAN and INVITE commands in server. The affected file is
578 lib/silcutil/unix/silcunixutil.c.
580 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
582 * Removed the command destructor entirely from the server's
583 command and command reply routines. It is not needed, and
584 its usage was buggy and caused crashes. Affected files are
585 silcd/command[_reply].[ch].
587 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
589 * Cancel protocol and NULL sock->protocol if timeout
590 occurred during protocol. Affected file silcd/server.c.
592 * Cancel protocol timeouts always before calling the final
593 callback, to assure that after final callback is called
594 no other state will be called for the protocol anymore.
595 Affected file silcd/protocol.c.
597 * Print error log if incoming connection configuration could
598 not be found. Affected file silcd/server.c.
600 * Fixed JOIN command to correctly save the founder mode
601 to the client on normal SILC server, when the channel
602 was created by the router. Affected file silcd/command.c.
604 * Fixed LIST command (hopefully) to send correct reply
605 packets. Affected file silcd/command.c.
607 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
609 * The silc_packet_receive_process now returns FALSE if the
610 read data was invalid packet, and TRUE if it was ok.
612 The server now checks that if unauthenticated connection
613 sends data and its processing fails the server will close
614 the connection since it could be a malicious flooder.
616 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
618 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Make sure the warning about error opening a log file is
621 printed only once and not everytime it fails (produces
622 too much useless log). Affected file lib/silcutil/silclog.c.
624 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
626 * Made the silc_server_daemonise() function more readable.
627 Affected file silcd/server.c.
629 * Pid file is now optional, the user may comment it out from
630 the config file. Removed define SILC_SERVER_PID_FILE, we
631 don't need a default any longer. Affected file
632 configure.in.pre, lib/Makefile.am.pre.
634 * Make some use of the pid file. The server now dies at startup
635 if it detects a valid pid file on his path. The server would
636 die anyway in this circumstance, because of the bind() failure.
637 Affected file silcd/silcd.c.
639 * No longer compiling lib/dotconf.
641 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Fixed JOIN command parsing not to crash. Affected file
644 lib/silcclient/command.c.
646 * Fied the NICK_CHANGE notify to add the new client entry
647 even it is resolved. This removes an <[unknown]> nick
648 thingy bug in the client. Affected file is
649 lib/silcclient/client_notify.c.
651 * Do not try to allocate 0 bytes (efence does not like it)
652 in lib/silccore/silccomand.c when encoding payload.
654 * Do not take IRCNICK as nickname in Irssi SILC client since
655 it is not possible to set nickname before hand connecting
656 the server (TODO has an entry about adding auto-nicking
659 * Changed the silc_server_command_pending to check whether
660 there already exists an pending entry with the specified
661 command, command identifier and pending callback. This is
662 to fix IDENTIFY and WHOIS related crashes that may register
663 multiple pending commands with same identifier. Affected
664 file silcd/command.c.
666 * Fixed the server to reconnect to the router even if it
667 was already reconnecting and EOF was received. This to
668 fix a possibility that the server wouldn't ever try to
669 auto-reconnect to the router. Affected file silcd/server.c.
671 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
673 * Fixed the server's password authentication to use the
674 length of the locally saved password, and not the one
675 sent in the packet. Affected file silcd/protocol.c.
677 * Fixed same password authentication problem in the
678 Authentication Payload handling routines in
679 lib/silccore/silcauth.c.
681 * Yet another password authentication problem fixed with
682 channel password handling in silcd/command.c.
684 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
686 * If first character of string in silc_parse_userfqdn is '@'
687 then do not parse it. Affected file is
688 lib/silcutil/silcutil.c.
690 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Fixed minor bug in IDENTIFY command reply sending, which
693 caused various weird problems during JOIN when it was
694 resolving names for users. Affected file silcd/command.c.
696 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Fixed the IDENTIFY command reply sending to chech better valid
699 clients. It was possible to send incomplete list of replies.
700 Affected file silcd/command.c.
702 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Added silc_client_command[s]_[un]register functions now to
705 dynamically register the commands in client library. Removed
706 the static table of commands. This allows the client library
707 to call commands without causing the application to know about
708 what commands library has called.
710 Removed the INFO command reply kludge to detect when the command
711 was called by library. Now library use its own command reply
712 function for INFO command.
714 Added function silc_client_command_call to call a command.
715 Application can use it to call command, not access the structure
718 Now all commands that are sent by the client library (not
719 explicitly sent by application) use own command reply functions.
721 Affected files around lib/silcclient/ and in
722 irssi/src/silc/core/.
724 * Fixed the WHOIS command reply sending to chech better valid
725 clients. It was possible to send incomplete list of replies.
727 Fixed the WHOIS and IDENTIFY to send the request to router
728 if normal server did not do it and did not find any results.
730 Affected file silcd/command.c.
732 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
734 * Moved the internal data from SilcClient context into its
735 own file, not accesible to application. Affected files
736 lib/silcclient/client.h and lib/silcclient/client_internal.h,
737 and other files in client library.
739 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Added doc/examples installation target in Makefile.am.pre.
744 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
746 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
747 commands the found client entry will be removed from the
748 cache, after notifying application about the error. Affected
749 file lib/silcclient/command_reply.c.
751 * Changed the /MSG to check for exact nickname user gave, and
752 not let `nick' match `nick@host' if it is only one found. Now,
753 user must type the exact nickname (like nick@host2) even if
754 there are no more than one same nicks found. This is to avoid
755 a possibility of sending nickname to wrong nickname since
756 `nick' could match `nick@host'. Affected file is
757 irssi/src/core/silc-servers.c.
759 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
761 * Do not print "you are now server operator" or similar when
762 giving /away command. Affected files are
763 irssi/src/silc/core/client_ops.c, silc-servers.h.
765 * Made the silc_server_command_pending_error_check to send
766 the same command reply payload it received back to the
767 original sender of the command. This way all arguments
768 that was received by the server will be received by the
769 client too. Affected file silcd/command.c.
771 * Added the silc_idcache_add to return the created cache entry
772 to a pointer. Affected file lib/silccore/silcidcache.[ch].
774 * Add global clients to expire if they are not on any channel.
775 This is because normal server will never know if they signoff
776 if they are not on any channel. The cache expiry will take
777 case of these entries. This is done by normal servers only.
778 The affected files are silcd/command_reply.c,
779 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
781 * If server receives invalid ID notification for WHOIS or
782 IDENTIFY and the ID exists in the lists, it is removed.
783 Affected file silcd/command_reply.c.
785 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
786 in client then client entry that it matches is searched and
787 the nickname is printed on the screen for user. Affected
788 file irssi/src/silc/core/client_ops.c.
790 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
792 * Use cache entry expire time in the LIST command reply to
793 purge old entries from the cache after the LIST command
794 reply has been received. This way we don't have non-existent
795 entries in the cache for too long. Affected file is
796 silcd/command_reply.c.
798 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
800 * If we are normal server, and we've not resolved client info
801 in WHOIS or IDENTIFY from router, and it is global client,
802 we'll check whether it is on some channel. If it is not
803 then we cannot be sure about its validity and will resolve it
804 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
805 file silcd/command.c.
807 * Search channel by name (if possible) rather than by ID
808 in IDENTIFY command's command reply. Affected file is
809 silcd/command_reply.c.
811 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Distribute to the channel passphrase in CMODE_CHANGE notify.
814 Updated specs and implemented it. Affected file silcd/command.c,
815 silcd/packet_send.c and silcd/packet_receive.c.
817 * Implemented the <founder auth> payload handling in the JOIN
818 command. If provided all conditions for channel joining
819 except requirement to provide correct passphrase can be
820 overrided by the channel founder. Updated the protocol specs.
821 Affected file silcd/command.c.
823 Added support for founder auth in JOIN command in client
824 library. Fixed the parsing of the JOIN command now to support
825 all options as they should be. The affected file is
826 lib/silcclient/command.c.
828 * Optimized the WHOIS and IDENTIFY commands to send the request
829 to router only if it includes nicknames or other names. If
830 they include only IDs then check the local cache first before
831 routing. Affected file is silcd/command.c.
833 * Added channels topic announcements. Affected file is
834 silcd/packet_receive.c and silcd/server.c.
836 * Fixed the silc_server_send_notify_topic_set to really destine
837 the packet to channel. Affected file silcd/packet_send.c.
839 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
840 library. Affected file lib/silcclient/client_notify.c.
842 * Added UMODE announcements. Affected file silcd/server.c.
844 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Memory leak fixes in:
848 lib/silcutil/silcsockconn.c
849 lib/silcske/silcske.c
852 lib/silccrypt/silcpkcs.c
853 lib/silccore/silccommand.c
854 lib/silccore/silcidcache.c
859 * ROBOdoc documented the lib/silcske/groups.h file and a
860 bit changed the interface for better.
862 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
864 * Update the client entry context in the ID cache after
865 nick change. Affected file lib/silcclient/command.c.
866 Fixes the CUMODE command when regaining founder privileges,
867 and a little WHOIS problem.
869 * Fixed silc_net_gethostbyname to correctly call the
870 inet_ntop. Affected file lib/silcutil/silcnet.c.
872 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
874 * Added IPv6 support checking to the configure.in.pre, added
875 also --enable-ipv6 option to override the check. Affected
876 file configure.in.pre.
878 * The silc_thread_create now calls the start function
879 directly if threads support is not compiled in. Removes
880 ugly #ifdef's from generic code. Affected files are
881 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
883 * Added silc_net_gethostby[name/addr]_async to asynchronously
884 resolve. Affected files are lib/silcutil/silcnet.[ch].
886 * Added support for rendering IPv6 based server, client and
887 channel IDs. Affected file lib/silcutil/silcutil.c.
889 * Added support for creating IPv6 based server IDs. Affected
890 file is silcd/serverid.c.
892 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
894 * Added silc_net_gethostby[addr/name] into the
895 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
896 routines. Added silc_net_is_ip[4/6]. Affected file is
897 lib/silcutil/unix/silcunixnet.c. All routines that take
898 address as argument now supports both IPv4 and IPv6 addresses.
900 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
902 * Fixed LIST command reply sending in server. Affected file
905 * Server now sends the kicker's client ID in the KICK notify
906 to the kicked client. Affected file silcd/command.c.
908 * The client library now parses the kickers client ID and
909 UI displays it. Affected files lib/silcclient/client_notify.c
910 and irssi/src/silc/core/silc-channels.c, module-formats.c.
912 * Made all payload parsing function prototypes consistent.
913 They all take now const unsigned char * and uint32 pair as
914 the payload data instead of SilcBuffer. Changes all around
915 the source tree. Other unsigned char* -> const unsigned char*
916 changes around the tree as well.
918 * Optimized SFTP client and server packet sending not to
919 allocate new buffer for each packet but to recycle the
920 first allocated buffer. Affected files are
921 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
923 * Optimized the SFTP client to use SilcList instead of
924 SilcDList for requests, because it is faster. Affected file
925 is lib/silcsftp/sftp_client.c.
927 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
928 into lib/silccore/silcid.[ch].
930 Renamed silcpayload.[ch] into silcargument.[ch].
932 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
934 * If client entry is deleted with active key agreement
935 session, abort the session.
937 The silc_client_abort_key_agreement now calls the completion
938 callback with new SILC_KEY_AGREEMENT_ABORTED status.
940 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
943 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Don't use __restrict in older GCC's. Affected file is
946 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
948 * silc_net_localhost now attempts to reverse lookup the
949 IP/hostname. Affected file lib/silcutil/silcnet.c.
951 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
952 command. It can be used to gain founder privileges at
953 the same time when joining the channel.
955 Defined that the SILC_NOTIFY_TYPE_KICKED send the
956 kicker's client ID as well. Updated protocol specs.
958 Defined that the server must send SILC_COMMAND_IDENTIFY
959 command reply with error status to client who sent
960 private message with invalid client ID.
962 Updated the protocol specification.
964 * Added silc_server_send_command_reply to send any
965 command reply. Affected file silcd/packet_send.[ch].
967 * Added silc_id_payload_encode_data to encode ID payload
968 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
970 * The server now send IDENTIFY command reply with error
971 status if client ID in private message is invalid. Affected
972 file silcd/packet_receive.c.
974 * Save the server key file with server's IP address in
975 the filename instead of hostname. The affected file is
976 irssi/src/silc/core/client_ops.c.
978 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
980 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
983 * Added libtool support for compiling shared objects in
984 lib/silcsim. Affected file configure.in.pre and
985 lib/silcsim/Makefile.am. Original patch by cras.
987 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Pid file configuration, and server's config file fixes
990 patch by toma. Updated CREDITS file.
992 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Fixed silc_client_channel_message to not try to decrypt
995 the message twice if it resolved the destination client
996 information. This could cause of dropping one channel
997 message. Affected file lib/silcclient/client_channel.c.
999 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1002 lib/silcclient/client.c. This function is used when the SILC
1003 Client is run under some other scheduler, or event loop or
1004 main loop. On GUI applications, for example this may be
1005 desired to used to run the client under the GUI application's
1006 main loop. Typically the GUI application would register an
1007 idle task that calls this function multiple times in a second
1008 to quickly process the SILC specific data.
1010 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1012 * Fixed silc_server_drop() for dropping the supplementary
1013 groups as well, this could cause a security hole on some
1016 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1021 * Write PID file after dropping privileges. Added -F option
1022 to run server on foreground. A patch by debolaz.

1025 * Fixed MOTD to return the MOTD file server name. Affected
1026 file silcd/command.c.
1028 * Added INFO command reply handling to the Irssi SILC Client.
1029 Affected file irssi/src/silc/core/client_ops.c.
1031 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1033 * Fixed the silc_idcache_list_* routines to really support
1034 the dynamic list. Fixes a crash. Affected file is
1035 lib/silccore/silcidcache.c.
1037 * Fixed the LIST command reply to really call LIST command's
1038 pending callbacks. Affected file silcd/command_reply.c.
1040 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Update conn->local_entry->nickname after giving NICK
1043 command. Affected file lib/silcclient/command.c.
1045 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1047 * Added the [pid] option to the silcd configuration file
1049 Affected files: serverconfig.[ch] and silcd.c
1051 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Save fingerprint in WHOIS command reply in server.
1054 Affected file silcd/command_reply.c.
1056 * Fixed NICK commands pending callback registration.
1057 Affected file lib/silcclient/command.c.
1059 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1061 * Use ++server->cmd_ident when sending commands in server,
1062 instead of random number. Affected file silcd/command.c.
1064 * Fixed GETKEY command reply to call actually GETKEY pending
1065 command callbacks. Affected file silcd/command_reply.c.
1067 * A bit stricter check for nicknames. Check for same nickname
1068 in NICK command also. Affected file silcd/command.c.
1070 * Do not call INFO command everytime client ID changes, only
1071 during first connecting. Affected file lib/silcclient/client.c.
1073 * Set the new nickname only after successful command reply for
1074 NICK command is returned by server. Affected file
1075 lib/silcclient/command.c.
1077 * Remove nicknames from nicklist during server_signoff notify.
1078 Should fix /NAMES bit more. The affected file is
1079 irssi/src/silc/core/silc-channels.c.
1081 * Added `fingerprint' field to the SilcIDListData in the
1082 silcd/idlist.h to hold the fingerprint of the client's
1085 Send the fingerprint of the client's public key in WHOIS
1088 Affected files silcd/command.c, and silcd/idlist.[ch].
1090 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1091 create fingerprint from given data.
1093 * Show the fingerprint of the client's public key in WHOIS.
1094 Affected files irssi/src/module-formats.[ch] and
1095 irssi/src/silc/core/client_ops.c.
1097 * Format the multiple same nicknames also during JOIN and
1098 NICK_CHANGE notifys. Affected file is
1099 lib/silcclient/client_notify.c.
1101 * Do not print error on screen for invalid private message
1102 payload since it can come if someone is sending private
1103 messages with wrong key. Affected file
1104 lib/silccore/silcprivate.c.
1106 * Fixed multiple concurrent /PING crash. Affected file
1107 lib/silcclient/command.c.
1109 * Changed the wrong ID encoding. All IP addresses must be
1110 in MSB first order in encoded format. They were encoded
1111 wrong and was in LSB format. Affected files are
1112 silcd/serverid.c, lib/silcutil/silcutil.c.
1114 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1116 * Call the `connect' client operation through the scheduler
1117 in case of error. Affected file lib/silcclient/client.c.
1119 * Call the `failure' client operation even if the error
1120 occurred locally during a protocol. Affected file is
1121 lib/silcclient/protocol.c.
1123 * Added support of sending LIST command to router from normal
1124 server. This way normal server can get list of all channels
1125 in the network too. Fixed the channel list sending in the
1126 server too. Affected files are silcd/command.c, and
1127 silcd/command_reply.[ch].
1129 * Added silc_server_update_channels_by_server and
1130 silc_server_remove_channels_by_server. They are used during
1131 disconnection of primary router and in backup router protocol.
1132 Affected file silcd/server_util.[ch], silcd/server.c and
1133 silcd/server_backup.c.
1135 * Fixed channel adding to global list in IDENTIFY command
1136 reply in server. Affected file silcd/command_reply.c.
1138 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * If the incoming packet type is REKEY or REKEY_DONE process
1141 that packet always synchronously. Fixes yet another MAC
1142 failed error on slow (dialup) connections. Affected file
1143 lib/silcclient/client.c and silcd/server.c.
1145 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Call check_version SKE callback for initiator too. Affected
1148 file lib/silcske/silcske.c.
1150 * Implemented fix for security hole found in the SKE that was
1151 fixed in the specification few days back; the initiator's
1152 public key is now added to the HASH value computation.
1153 Added backwards support for the old way of doing it too, for
1154 old clients and old servers. Affected file is
1155 lib/silcske/silcske.c.
1157 * Enabled mutual authentication by default in SKE. If initiator
1158 is not providing mutual authentication the responder will
1159 force it. This will provide the proof of posession of the
1160 private key for responder. The affected files are
1161 lib/silcclient/protocol.c and silcd/protocol.c.
1163 * Do not cache anymore the server's public key during SKE.
1164 We do mutual authentication so the proof of posession of
1165 private key is done, and if the server is authenticated in
1166 conn auth protocol with public key we must have the public
1167 key already. Affected file silcd/protocol.c.
1169 * Added new global debug variable: silc_debug_hexdump. If
1170 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1171 file lib/silcutil/silclog.[ch].
1173 * Fixed compilation warning due to char * -> const char *.
1174 Affected files lib/silcutil/silcnet.h, and
1175 lib/silccore/silcauth.[ch].
1177 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * Fixed CMODE command when new channel key was created. If
1180 the creation failed the old key was removed. Next time giving
1181 same command would crash the server since the old key was
1182 freed already. Affected file silcd/command.c.
1184 * Fixed the silc_server_announce_get_channels to not crash
1185 on reconnect. Affected file silcd/server.c.
1187 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1189 * Added silc_log_set_debug_string function to set a regex
1190 string to match for debug output. Only the function names,
1191 or filenames matching the given debug string is actually
1192 printed. This way it is possible to filter out those debug
1193 strings that user is not interested in.
1195 Fixed a bug in silc_string_regexify.
1197 Affected files lib/silcutil/silclog.[ch], and
1198 lib/silcutil/unix/silcunixutil.c.
1200 * Changed the -d options in both server and Irssi SILC client
1201 to take the debug string as argument. Affected files
1202 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1204 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Added silc_hash_babbleprint to create a Bubble Babble
1207 Encoded fingerprint. The encoding is developed by Antti
1208 Huima (draft-huima-babble-01.txt), and it creates human
1209 readable strings out of binary data. Affected file
1210 lib/silccrypt/silchash.[ch].
1212 * Print the babble print now in addition of fingerprint as well
1213 in Irssi SILC client. Affected files are
1214 irssi/src/fe-common/silc/module-formats.[ch],
1215 irssi/src/fe-common/silc/core/client_ops.c.
1217 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Fixed a security problem found in SKE. The initiator's
1220 public key too is now added to the HASH hash value creation
1221 which is signed by the responder to create the SIGN value.
1222 This will prevent anyone in the middle to lie to the responder
1223 about the initiator's public key. If this is done now, the
1224 man in the middle will get caught. Updated the protocol
1227 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Better installation directory handling. Configure module
1230 paths and other paths automatically to example_silc* files
1231 in doc/. A patch by toma.
1233 * Fixed compiler warning from MPI library, and from SILC RNG.
1236 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1237 It can be configured with ./configure. A patch by toma.
1239 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * Find correct make to use in prepare-clean. A patch by
1242 toma. Affected file prepare-clean.
1244 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1246 * Added irssi variables use_auto_addr, auto_bind_ip,
1247 auto_bind_port and auto_public_ip.
1249 * Changed the interface for silc_client_send_key_agreement
1250 in lib/silcclient/silcapi.h
1254 irssi/src/silc/core/silc-core.c
1256 lib/silcclient/silcapi.h
1257 irssi/src/silc/core/silc-channels.c
1258 lib/silcclient/client_keyagr.c
1261 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Added silc_pkcs_public_key_compare to compare two
1264 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1266 * Check that the client who set the founder mode on the
1267 channel is the same client that is giving the founder
1268 mode to itself. It is done by comparing the saved public
1269 key (it is saved even in the authentication is passphrase).
1270 Affected file silcd/command.c.
1272 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1274 * Do not process packet for disconnected socket connection.
1275 Affected file lib/silccore/silcpacket.c.
1277 * Process the DISCONNECT packet through scheduler in the
1278 client library. Affected file lib/silcclient/client.c.
1280 * Fixed the silc_client_packet_parse to not to increase
1281 the packet sequence number if the conn->sock and the
1282 current socket connection is not same. This can happen
1283 for example during key agreement when the conn includes
1284 multiple socket connections (listeners). Affected file
1285 lib/silcclient/client.c.
1287 * The sender of the file transfer request now provides also
1288 the pointer (listener) for the key exchange protocol. If
1289 the listener cannot be created then it sends empty key
1290 agreement and lets the receiver provide the listener.
1292 Added `local_ip' and `local_port' arguments to the
1293 silc_client_file_send. If they are provided they are used,
1294 if not then it will attempt to find local IP address, if
1295 not found or bind fails then the remote client will provide
1298 Affected files are lib/silcclient/client_ftp.c and
1299 lib/silcclient/silcapi.h.
1301 * Extended the FILE SEND command to support defining the
1302 local IP and port for key exchange listener. They are
1303 optional. Affected file irssi/src/silc/core/silc-servers.c.
1305 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Defined to WHOIS command reply the sending of fingerprint
1308 of the client's public key (if the proof of posession of the
1309 corresponding private key is verified by the server).
1310 Updated to the protocol specification.
1312 * Added support of receiving the client's public key's
1313 fingerprint in command reply in client library. Affected
1314 file is lib/silcclient/command_reply.c, and
1315 lib/silcclient/idlist.[ch].
1317 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Do not send over 128 chars long nickname to the server
1320 in NICK command. Affected file lib/silcclient/command.c.
1322 * Do not send over 256 chars long channel names to the server
1323 in JOIN command. Affected file lib/silcclient/command.c.
1325 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Assure that silc_server_close_connection cannot be called
1328 twice for same socket context. Affected file is
1331 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1333 * Send error message to application if opening file for
1334 writing during file transfer fails. Affected file is
1335 lib/silcclient/client_ftp.c.
1337 Remove all file transfer sessions for a client that we're
1338 removing from ID cache.
1340 Affected file is lib/silcclient/client_ftp.c.
1342 * Fixed silc_net_addr2bin to return correct address. Affected
1343 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1345 * Fixed file transfer session removing on signoff notify.
1346 Affected file irssi/src/silc/core/silc-servers.c.
1348 * Added the SilcClientFileError to be returned in the monitor
1349 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1350 Affected file lib/silcclient/silcapi.h.
1352 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Fixed a crash in silc_client_ftp_free_sessions and
1355 silc_client_ftp_session_free_client. Affected file
1356 lib/silcclient/client_ftp.c.
1358 * Added `disabled' field in the SilcChannelEntry in the server
1359 to indicate if the server entry is disabled. Affected file
1360 silcd/idlist.h, silcd/command[_reply].c.
1362 * SILC server adds now /var/run/silcd.pid everytime it is
1363 started. Affected file silcd/silcd.c.
1365 * Added silc_server_packet_send_clients to send a packet to
1366 the provided table of client entries. Affected file
1367 silcd/packet_send.[ch].
1369 * Fixed a crash in client resolving in client_prvmsg.c in
1370 client library. Affected file lib/silcclient/client_prvmsg.c.
1372 * Do not actually remove the client directly from ID cache
1373 during SERVER_SIGNOFF, but invalidate it. This way we
1374 preserve the WHOWAS info for the client. Affected file
1375 silcd/server_util.c.
1377 * Fixed SERVER_SIGNOFF notify handling in the server. The
1378 server is now able to process incoming SERVER_SIGNOFF notify
1379 for a server that it doesn't even know about. It will remove
1380 the clients provided in the notify. Affected file
1381 silcd/packet_receive.c.
1383 * Check for partial packet in data queue after every packet that
1384 was found from the queue. Return and wait for more data if
1385 there is partial data in queue. Affected file is
1386 lib/silccore/silcpacket.c.
1388 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Added SilcClietFileError enum to indicate error in
1391 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1392 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1393 Affected files lib/silcclient/silcapi.h and
1394 lib/silcclient/client_ftp.c.
1396 * Check that newsize in silc_buffer_realloc is larger than
1397 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1399 * Added better monitor of file transfers. It now monitors
1400 key agreement protocol during the file transfer too. Added
1401 error reporting too. Affected files
1402 irssi/src/silc/core/silc-servers.c,
1403 irssi/src/fe-common/silc/module-formats.[ch].
1405 * Wrote a help file for FILE command.
1407 * Added silc_rng_global_get_byte_fast to get not-so-secure
1408 random data as fast as possible. Random data is read from
1409 /dev/urandom if available and from the SILC RNG if not
1410 available. It is used in padding generation. Affected file
1411 lib/silccrypt/silcrng.[ch].
1413 * All packets in client library are now processed synchronously.
1414 Optimized packet processing a lot. Affected file
1415 lib/silcclient/client.c.
1417 * All server connection packets are processing synchronously
1418 now in server, to optimize packet processing. Affected file
1421 * Include files are installed now only in Toolkit distribution
1422 if make install is given. Affected files: all Makefile.am's.
1424 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Assure that silc_client_notify_by_server_resolve does not
1427 resolve the client information multiple times. If it cannot
1428 be found by the first it cannot be found at all. Affected
1429 file lib/silcclient/client_notify.c.
1431 * Fixed WHOWAS command reply calling. Affected file
1432 lib/silcclient/command_reply.c.
1434 * Removed all references to silc_idlist_get_client from the
1435 Irssi SILC client since that call is internal call used by
1436 the library. The Irssi SILC client will use now client
1437 retrieval functions found in silcapi.h.
1439 * Fixed a bug in resolving nickname info before sending
1440 private message. It used freed memory. Affected file
1441 irssi/src/silc/core/silc-servers.c.
1443 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Assure my_channels statistics cannot go negative in server.
1446 Affected files silcd/server.c, silcd/server_util.c.
1448 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1452 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * Win32 Toolkit changes. Affected files

1458 lib/sftp/sftp_fs_memory.c.
1460 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Added silc_net_localip to return local host's IP address.
1463 Affected file lib/silcutil/silcnet.[ch].
1465 * If key exchange or rekey protocol is active for a connection
1466 parse all packets syncronously since there might be packets
1467 in packet queue that we are not able to process without first
1468 processing packets before them. Affected file silcd/server,
1469 lib/silcclient/client.c.
1471 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1472 whether library should continue processing the packet.
1473 Affected file lib/silccore/silcpacket.h.
1475 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1476 SilcSFTPMonitorData to SFTP server to monitor various
1477 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1478 lib/silcsftp/sftp_server.c.
1480 * Added silc_file_size to return file size. Affected file
1481 lib/silcutil/silcutil.[ch].
1483 * Implemented the file transfer support for the client library.
1484 Added preliminary support for simple client to client one-file
1485 transmission. Affected file lib/silcclient/client_ftp.c,
1486 lib/silccilent/client.[ch].
1488 * Added new local command FILE to the Irssi SILC Client.
1489 It is used to perform the file transfer. It has subcommands
1490 SEND, RECEIVE, SHOW and CLOSE. Affected files
1491 irssi/src/silc/core/client_ops.c,
1492 irssi/src/silc/core/silc-server.[ch].

1501 * Renamed silc_file_read and silc_file_write to functions
1502 silc_file_readfile and silc_file_writefile. Added function
1503 silc_file_open and silc_file_close. Affected files
1504 lib/silcutil/silcutil.[ch].
1506 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Resolve the client info when received private message or
1509 channel message for a client which nickname we don't know.
1510 Affected files lib/silcclient/client_prvmsg.c and
1511 lib/silcclient/client_channel.c.
1513 * Do not crash in /KEY if client is not connected. Affected
1514 file irssi/src/silc/core/silc-channels.c.
1516 * Added SilcClientStatus field to the SilcClientEntry in the
1517 lib/silcclient/idlist.h.
1519 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1520 is incomplete and is being resolved, it won't be resolved
1523 Make sure also that USERS command reply does not resolve
1524 twice information. Affected file is
1525 lib/silcclient/command_reply.c.
1527 Make sure that silc_client_get_clients_by_list does not
1528 resolve twice same information.
1530 * Check for valid client->id in the silc_server_free_client_data.
1531 Affected file silcd/server.c.
1533 * Fixed /GETKEY nick@server not to crash if the server entry
1534 is not found. Affected file lib/silcclient/command.c.
1536 * Fixed the silc_server_check_cmode_rights to check the
1537 requested modes correctly. Affected file silcd/command.c.
1539 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Better checks for non-printable chars in nick added.
1542 Affected file silcd/command.c.
1544 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1546 * Call the silc_server_udpate_servers_by_server in the
1547 primary router that comes back online in the backup resuming
1548 protocol. Otherwise it routes packets wrong. Affected file
1549 silcd/server_util.[ch], silcd/server_backup.c.
1551 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1554 lib/silcutil/silcbuffmt.[ch].
1556 * Redefined the SILC packet header to include the padding
1557 length. Affected file lib/silccore/silcpacket.[ch].
1559 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1560 length for maximum padding up to 128 bytes). Affected
1561 file lib/silccore/silcpacket.h.
1563 * Removed all backwards support for old 0.5.x MAC thingies.
1564 The SILC packet header change makes it impossible to be
1565 backwards compatible.
1567 * Send the ENDING packet with timeout in the backup resuming
1568 protocol. This is to assure that all routers has connected
1569 to the primary router. Affected file silcd/server_backup.c.
1571 * Changed the RNG to take the first IV from random data. It
1572 used to take it from zero actually. Changed the RNG also
1573 to use /dev/urandom during session. /dev/random is used
1574 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1576 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Changed the SILC packet header to have the first two bytes
1579 (the packet length) encrypted. Affected files aroung the
1580 code tree, lib/silccore/silcpacket.[ch]. Removed the
1581 SilcPacketCheckDecrypt callback. It is not needed anymore
1582 since the silc_packet_receive_process will determine now
1583 whether the packet is normal or special.
1585 * Implemented the unidirectional MAC keys. Affected files
1586 lib/silcske/silcske.c, silcd/protocol.c and
1587 lib/silcclient/protocol.c.
1589 * Implemented the packet sequence number to the MAC computation.
1590 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1591 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1592 lib/silcclient/protocol.c.
1594 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Allow backup router to announce servers. All servers
1597 announced by backup router are added to the global list
1598 automatically. Update hte server's socket to our primary
1599 router also when backup router announces a server.
1600 Affected file silcd/packet_receive.c.
1602 * Do not update the client->router in the function
1603 silc_server_udpate_clients_by_server if the client is on
1604 global list. We might fail to find any specific server
1605 for locally connected clients and local cell clients. They
1606 should still use the `from' and not `to' as client->router.
1607 This fixes backup router resuming protocol. Affected file
1608 silcd/server_util.c.
1610 * Decrease channel statistics count only if the channel
1611 deletion worked. Affected files are silcd/server.c and
1612 silcd/server_util.c.
1614 * Added silc_server_update_servers_by_server to update origin
1615 of all server entries. Used during backup router protocol.
1616 Affected files silcd/server_util.[ch], silcd/server.c. and
1617 silcd/backup_router.c.
1619 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1620 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1621 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1622 lib/silccrypt/silchmac.c.
1624 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Assure that router cannot reroute the same channel message
1627 to the sender. Affected file silcd/packet_receive.c.
1629 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * Made better checks that the channel message is not sent
1632 to the router it came from. Affected file is
1633 silcd/packet_send.c. Fixed memory leak too.
1635 * Announce informations for incoming router connection, but
1636 only after checking if it is replaced by backup router.
1637 Affected file silcd/packet_receive.c.
1639 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Fixed the backup resuming protocol to work in multiple
1642 router environment. Affected file silcd/server_backup.c.
1644 * Route packet only to one router in the function
1645 silc_server_packet_send_to_channel. Affected file is
1646 silcd/packet_send.c.
1648 * Fixed silc_server_send_notify_dest to set the broadcast
1649 flag. Fixed the silc_server_send_notify_topic to actually
1650 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1651 Affected file silcd/packet_send.c.
1653 * Changed the SFTP Filesystem interface. Changed the
1654 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1655 the filesystem operation function. The SilcSFTPFilesystem
1656 is now a context that is allocated by all filesystem allocation
1657 functions and it already includes the operations structure
1658 and filesystem specific context. It is given as argument
1659 now to the silc_sftp_server_start. This made the interface
1660 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1661 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1663 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Changed the backup router adding and getting interfaces
1666 in the server. The router that will be replaced by the
1667 specified backup router is now sent as argument. Affected
1668 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1671 * Added silc_net_addr2bin_ne to return the binary form of
1672 the IP address in network byte order. Affected files
1673 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1675 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Check for existing server ID in silc_server_new_server
1678 and in silc_server_connect_to_router_final and remove the
1679 old entry if it exists. Affected file silcd/packet_receive.c,
1682 * Send the channel message always to only one router, either
1683 in upstream or downstream. Affected file is
1684 silcd/packet_send.c.
1686 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Wrote the definition of the backup resuming protocol to the
1689 protocol specification.
1691 * Removed one redundant channel key generation from normal
1692 server during joining procedure. Removed one redundant
1693 channel key sending from server to router during joining
1694 procedure. Affected file silcd/command.c.
1696 * Made minor bugfixes to the backup router resuming protocol.
1697 Affected file silcd/server_backup.c, server.c.
1699 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Added --disable-asm configuration option. Affected files
1702 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1705 * Implemented the backup resuming protocol that is used to
1706 resume the primary router position in the cell after the
1707 primary router comes back online. Affected files
1708 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1709 and silcd/server_util.[ch].
1711 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Sleep two (2) seconds after sending QUIT command to server.
1714 Affected file lib/silcclient/command.c.
1716 * Assure that if outgoing data buffer is pending do not force
1717 send any data. Affected file silcd/packet_send.c.
1719 * Assure that if outgoing data buffer is pending do not force
1720 send any data. Affected file lib/silcclient/client.c.
1722 * Implemented the backup router support when the primary router
1723 goes down. The servers and routers can now use the backup
1724 router as new primary router without loosing connectivity.
1726 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1729 in the server to indicate disabled entry. All data read
1730 from the connection will be ignored and no data is sent
1731 for entry that is disabled. Affected files are
1732 silcd/idlist.h, silcd/server.c.
1734 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Created SFTP client and server test programs in the
1737 lib/silcsftp/tests directory.
1739 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Implemented memory filesystem (virtual filesystem) for
1742 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1745 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Implemented the SFTP (SSH File Transfer Protocol) to the
1748 lib/silcsftp. It includes SFTP client and SFTP server
1751 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Moved lib/silccore/silcprotocol.[ch] to the
1754 lib/silcutil library.
1756 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1757 take variable argument list pointer as argument. Affected
1758 file lib/silcutil/silcbuffmt.[ch].
1760 * Added silc_buffer_set function that is used to set data
1761 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1762 Affected file lib/silcutil/silcbuffer.h.
1764 * Changed various routines in the core library to use the new
1765 silc_buffer_set instead of allocating new buffer only for
1768 * Added 64-bit value formatting and unformatting support to the
1769 silc_buffer_[un]format routines. Affected file is
1770 lib/silcutil/silcbuffmt.[ch].
1772 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1773 to includes/bitmove.h.
1775 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Fixed channel user mode saving in client library. Affected
1778 file lib/silcclient/command[_reply].c.
1780 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Defined the file transfer to the SILC Protocol. Added
1783 new packet type SILC_PACKET_FTP and defined File Transfer
1784 Payload. The mandatory file transfer protocol is SFTP
1785 (SSH File Transfer Protocol). Affected file in addition
1786 of the internet draft is lib/silccore/silcpacket.h.
1788 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1789 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1790 is used as part of backup router protocol when the primary
1791 router of the cell is back online and wishes to resume
1792 the position as primary router.
1794 * Redefined the MAC generation keys in the protocol. The
1795 same key is not used anymore in both direction. Both
1796 direction will now use different keys for sending and
1797 receiving. This fixes a potential security flaw. This
1798 change causes incompatibilities in the protocol.
1800 * Redefined also the MAC computation from the packet.
1801 An packet sequence number is now added to the MAC
1802 computation. This prevents possible replay attacks against
1803 the protocol. This change too causes incompatibilities
1806 Added `sequence' field to the SilcPacketContext to hold
1807 the current sequence number for the packet.
1809 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Added `created' field to the SilcIDListData in the file
1812 silcd/idlist.h to indicate the time when the entry was
1815 * Added `created' field to the SilcChannelEntry too. Affected
1816 file silcd/idlist.h.
1818 * Added `creation_time' aguments to all the announcement functions
1819 in the server. If it is provided then only the entries that
1820 was created after the provided time frame are actually
1821 announced. Affected file silcd/server.[ch].
1823 * The protocol says that the Channel ID's IP address must be
1824 based on the router's IP address. Added check for this in
1825 the silc_server_new_channel when processing incoming New Channel
1826 Payload. Affected file silcd/packet_receive.c.
1828 * Print out the correct version with --version in SILC client.
1829 Affected file irssi/src/silc/core/silc-core.c.
1831 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Fixed WHOWAS command to check for completnes of the client
1834 entry always, not just when the command is coming from client.
1835 Affected file silcd/command.c.
1837 * Added new function silc_server_packet_queue_purge to purge the
1838 outgoing data queue to the network. After the function returns
1839 it is guaranteed that the outgoing packet queue is empty.
1840 Affected file silcd/packet_send.[ch].
1842 * Purge the outgoing packet queue in the rekey protocol's final
1843 callback to assure that all rekey packets go to the network
1844 before quitting the protocol. Affected file silcd/server.c.
1846 * Added silc_client_packet_queue_parse as similar function as
1847 in server to the client library. The affected file is
1848 lib/silcclient/client.c.
1850 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Splitted silcd/server.c and created silcd/server_util.[ch]
1853 for utility functions.
1855 * Added new socket flag SILC_SF_DISABLED to indicate that the
1856 connection is open but nothing can be sent to or received from
1857 the connection. Affected file lib/silcutil/silsockconn.[ch].
1858 The checking for disabled socket is checked in the low level
1859 silc_socket_write and silc_socket_read functions.
1861 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Allow only nicknames and channel names that fits into the
1864 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1866 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * When processing JOIN command reply in server check that if
1869 the channel exists in our global list we'll move it the local
1870 list. Affected file silcd/command_reply.c.
1872 * Fixed the check whether client is joined on the channel already
1873 in JOIN command. Affected file lib/silcclient/command.c.
1875 * Fixed the JOIN command reply to check whether the channel
1876 already exists. Affected file lib/silcclient/command_reply.c.
1878 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Added silc_ske_status_string to map the SKE error numbers
1881 to readable strings. The affected files are
1882 lib/silcske/silcske[_status].[ch].
1884 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Do not show the private channels on the WHOIS channel list
1887 as it is not allowed by the protocol. The affected file is
1890 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Assure that the packet length digged from the actual packet
1893 is something sensible in the silc_packet_decrypt_rest_special
1894 in lib/silccrypt/silcpacket.c.
1896 * Free and NULL the allocated pointer in silc_hmac_alloc if
1897 the HMAC allocation fails. The affected file is
1898 lib/silccrypt/silchmac.c.
1900 * Print the selected security properties to the log files in
1901 the server. Affected file silcd/protocol.c.
1903 * Add SKE's reference counter even if calling the completion
1904 callback manually. Otherwise it goes negative, although it
1905 does not cause any problems. The affected file is
1906 lib/silcske/silcske.c.
1908 * Remove the client entry with short timeout after giving the
1909 KILL command. Affected file lib/silcclient/command.c.
1911 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1912 case all found clients are already disconnected (WHOWAS would
1913 found them) in the server. Affected file silcd/command.c.
1915 * Update the last_receive (time of last data received) to be
1916 updated only when received private or channel message so that
1917 the idle time showed in WHOIS makes more sense.
1919 * Added boolean field `valid' in to the SilcClientEntry in the
1920 client library to indicate whether the entry is valid or not.
1921 This fixes the nickname change bug on channel when changing
1922 the nickname to be same than the old (like nick to Nick) the
1923 nickname formatter doesn't set the new nick anymore to Nick@host.
1924 Affected file lib/silcclient/idlist.[ch].
1926 * Now actually fixed the nickname changing on disconnection.
1927 Added new function silc_change_nick to the Irssi SILC Client.
1928 Affected file irssi/src/silc/core/client_ops.c,
1929 irssi/src/silc/core/silc-nicklist.[ch].
1931 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Check that the public key exists in the GETKEY command before
1934 trying to encode it. Affected file silcd/command.c.
1936 * Print some notifications on received public keys with GETKEY
1937 command in the Irssi SILC Client. Affected files are
1938 irssi/src/fe-common/silc/module-formats.[ch],
1939 irssi/src/silc/core/client_ops.c.
1941 * Use IDENTIFY command to resolve the server information in the
1942 GETKEY command instead of INFO command. Affected file
1943 lib/silcclient/command.c.
1945 * All command reply functions in the client library now calls
1946 the pending command reply callbacks even if an error has
1947 occurred. The server has done this a long time and now it was
1948 time to move the client library to this as well. Now all
1949 errors can be delivered back to the pending command reply
1950 callbacks if necessary. Affected files are
1951 lib/silcclient/command[_reply].[ch].
1953 * Change the nickname on disconnection back to the username
1954 because in reconnect the server will enforce it to it anyway.
1955 Affected file irssi/src/silc/core/silc-servers.c.
1957 * Fixed a config file parsing bug in the Irssi SILC client.
1958 Affected file irssi/src/silc/core/clientconfig.c.
1960 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * When printing the channel mode on JOIN, verify that the
1963 channel key and channel's HMAC are valid. Affected file
1964 irssi/src/silc/core/client_ops.c.
1966 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1969 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1970 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1972 * Removed channel key rekey task deleting from the function
1973 silc_server_save_channel_key. Affected file silcd/server.c.
1974 Added explicit timeout task context instead that is used to
1975 delete the task if we are registering a new task before the
1976 new task has elapsed.
1978 * When channel key rekey occurs the client library now saves
1979 the old channel key for a short period of time (10 seconds) and
1980 is able to use it in case some is still sending channel
1981 messages encrypted with the old key after the rekey. Affected
1982 file lib/silcclient/[idlist.h|client_channel.c].
1984 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Added check to the silc_server_new_id_real to not accept
1987 new ID if it is the sender's own ID. Affected file is
1988 silcd/packet_receive.c.
1990 * Assure that we do not announce ourself or the one we've
1991 sending our announcements when we're router and are announcing
1992 servers to our primary router. Affected file silcd/server.c.
1994 * Fixed silc_server_command_identify_check_client to assemble
1995 correct WHOIS packet. It send corrupted WHOIS packet and
1996 caused problem with router to router connections. Affected
1997 file silcd/command.c.
1999 Fixed also silc_server_command_whois_check the same way
2000 as for the IDENTIFY command.
2002 * Added new SilcIDListStatus to the server in the SilcIDListData
2003 structure. The status now includes the current status of
2004 the entry (like registered, resolved etc.). Affected file
2005 silcd/idlist.[ch]. Defined a bunch of different status types
2006 as well. This replaced the old boolean registered field as well.
2008 Added resolve_cmd_ident field to the SilcClientEntry structure
2009 too so that if the entry is for example being resolved so
2010 another command may attach to the same pending command reply
2011 without requiring to resolve the same entry again. This concept
2012 should optimize the WHOIS and the IDENTIFY resolving under
2013 heavy load by taking away unnecessary resolving for entries
2014 that are being resolved already.
2016 Added support for adding multiple pending commands for one
2017 command idenfier. Affected file silcd/command[_reply].[ch].
2019 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2020 before deleting the data. Otherwise the hash table will have
2021 freed data in comparison functions. Affected file is
2022 silcd/command_reply.c.
2024 * Fixed silc_idlist_replace_client_id to add the new entry to
2025 the cache with NULL nickname. Otherwise there will be invalid
2026 memory as the nickname after the nickname is freed. Affected
2027 file silcd/packet_receive.c.
2029 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2030 saved into wrong slots because the previous number of entries
2031 was not taken into account. Affected file silcd/idlist.c.
2032 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2034 * If we are router and we receive JOIN notify to a channel that
2035 does not have any users then notified client is marked as the
2036 channel founder, as it is it. The affected file is
2037 silcd/packet_receive.c
2039 * Added to the extended hash table API's table_del_*ext functions
2040 the destructor as argument too, so that the caller can decide
2041 which destructor to use or whether to use destructor at all.
2042 Affected file lib/silcutil/silchashtable.[ch].
2044 * Fixed ID Cache purging. It actually deleted the entries from
2045 the hash table after the data was freed. The hash table ended
2046 up comparing freed memory. The affected file is
2047 lib/silccore/silcidcache.c.
2049 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Fixed Irssi SILC client's KILL command's HELP syntax.
2053 * The USERS command now resolves the detailed user information
2054 if the userinfo field is missing. Affected file is
2055 lib/silcclient/command_reply.c.
2057 * Do not print error in silc_file_read if the read file does
2058 not exist. Just silently return NULL. Affected file is
2059 lib/silcutil/silcutil.c.
2061 * Fixed the silc_log_output to not wine about NULL filename
2062 and to not create some bogus " " filename. Affected file is
2063 lib/silcutil/silclog.c.
2065 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Fixed various printing bugs on the user interface in the
2068 Irssi SILC Client. Minor changes that were forgotten from
2071 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Fixed the configure.in.pre and the compilation and distribution
2074 environment to support the new autoconf 2.52. That version is
2075 now required to compile the CVS trunk.
2077 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2080 to generally parse user@fqdn format strings. Affected file
2081 lib/silcutil/silcutil.c.
2083 * Added nickname_format and nickname_force_format fields to the
2084 SilcClientParams structure. The first one defines the format
2085 for the nicknames that the library will enforce if the receives
2086 multiple same nicknames. The second one is boolean value and
2087 can be used to force the library to always enforce the format
2088 to the nicknames regardles whether there are multiple nicknames
2089 or not. This configurable formatting was employed to flexibly
2090 support accessing multiple nicknames from the user interface.
2091 The userinterface can now set the nicknames to what ever format
2092 they prefer. Affected file lib/silcclient/silcapi.h.
2094 Added function silc_client_nickname_format to the file
2095 lib/silcclient/idlist.c. It performs the nickname formatting.
2097 Added new field `hostname´ to the SilcClientEntry context.
2098 It holds the hostname of the client. Affected file is
2099 lib/silcclient/idlist.h.
2101 * Irssi SILC Client sets the nicknames in nick@hostn format.
2102 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2103 irssi/src/silc/core/silc-core.c.
2105 The WHOIS printing now also shows both the real nickname and
2106 the formatted nickname so that user knows how to access the
2107 user if there are multiple same nicknames cached. Affected
2108 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2109 printing formatting too to take the hostname now as a separate
2110 argument. The Affected file is
2111 irssi/src/fe-common/silc/modules-formats.[ch].
2113 * Changed the silc_client_get_clients_local to accept the formatted
2114 nickname as argument. It accepts the real nickname too but the
2115 formatted nickname can be used to find the true entry from
2116 multiple entries. Affected file lib/silcclient/silcapi.h and
2117 lib/silcclient/idlist.c.
2119 * Added nickname_format_parse field to the SilcClientParams.
2120 It is a callback function provided by the application to parse
2121 the nickname out of the formatted nickname string. The library
2122 calls it to get the nickname from the formatted string. Since
2123 the application generally knows better the format of the nickname
2124 string it parses it instead of the library, even though library
2125 encodes the formatted string. If the callback function is not
2126 provided then the library will use the string as is. The
2127 affected file is lib/silcclient/silcapi.h.
2129 * All the nickname strings passed to the client library in
2130 commands are now expected to be formatted nickname strings.
2131 If the command does not support the formatted nickname string
2132 it will assume that the sent string is the actual nickname.
2133 Affected file lib/silcclient/command.c.
2135 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Added public key authentication support to OPER and SILCOPER
2138 commands in the client library. Affected file is
2139 lib/silcclient/command.c.
2141 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Changed the get_auth_methdod client operation to be asynchronous.
2144 It can be async if the application resolves the authentication
2145 method from the server during the negotiation. Added new
2146 SilcGetAuthMeth completion callback that the application will
2147 call after resolving the authentication method.
2149 Added function silc_client_request_authentication_method that
2150 the application can use to resolve the authentication method
2151 from the server. Added also SilcConnectionAuthRequest callback
2152 that the library will call after the server has replied. The
2153 application can call this function if it does not know the
2154 current authentication method.
2156 Affected files are lib/silcclient/client.c and
2157 lib/silcclient/silcapi.h.
2159 * The Irssi SILC client now automatically resolves the authentication
2160 method incase any configuration information is not present (and
2161 currently there never is). The affected file is
2162 irssi/src/silc/core/client_ops.c.
2164 * Fixed public key authentication from the client library.
2165 Affected file lib/silcclient/protocol.c. Changed also the
2166 protocol specification about the public key authentication in
2167 the connection authentication protocol. The actual data to be
2168 signed is now computed with a hash function before signing.
2170 * Fixed the public key authentication from the server as well.
2171 Affected file silcd/protocol.c.
2173 * Removed the mlock()'s from the memory allocation routines.
2174 Affected file lib/silcutil/silcmemory.c. The ./configure does
2175 not check anymore for the mlock(). Affected file is
2178 * Fixed USERS command in server to allow the execution of the
2179 command for private and secret channels if the client sending
2180 the command is on the channel. Affected file silcd/command.c.
2182 * Fixed silc_client_get_clients_local to return the clients
2183 count correctly. It could return wrong value. Affected file
2184 lib/silcclient/idlist.c.
2186 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2189 types. The assembler optimizations seemed not to like 64-bit
2190 data types. The assmebler optimizations thus are now enabled
2191 also for BSD systems as opposed to only enable them for Linux.
2193 * Do not check for threads at all on BSD systems. Affected
2194 file configure.in.pre.
2196 * Removed -n and -h options from the Irssi SILC Client since
2197 they are not used in silc.
2199 * Fixed the prime generation to assure that the first digit
2200 of the generated random number is not zero since our conversion
2201 routines does not like number strings that starts with zero
2202 digit. If zero digit is seen the random number is regenerated.
2203 This caused some corrupted RSA keys when the zero first digit
2204 was met. Affected file lib/silcmath/silcprimegen.c.
2206 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Fixed WIN32 configuration in the ./configure script.
2209 Fixed to include xti.h on environments that has it.
2210 Patches by Carsten Ilchmann and andrew.
2212 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Changed the silc_id_create_client_id to be collision
2215 resistant. It is now assured that there cannot be created
2216 two same client ID's. I suspect that some weird bugs in
2217 the server were actually caused by duplicate Client IDs.
2218 Affected file silcd/serverid.[ch]. A router receiving
2219 new ID now also assures and informs the sending server
2220 if the ID caused collision.
2222 * Changed the silc_id_create_channel_id to also assure that
2223 there are no collisions.
2225 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Statement about ignoring the Mutual Authentication flag when
2228 performing rekey with PFS was a bit misleading. It is ignored
2229 if it was set in the initial negotiation, it cannot be even
2230 set in the rekey. Fixed in the ke-auth draft. Started the
2231 new versions of the protocol drafts in the doc/.
2233 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * Fixed a bug in silc_client_command_identify_save when saving
2236 new channel information. The channel name was no duplicated
2237 and caused crash on exit. Affected file is
2238 lib/silcclient/command_reply.c.
2240 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Fixed the getkey command handling in the server. Send just
2243 empty OK reply to the sender if the key could not be fetched
2244 (but everything else was ok, like the key just was not available).
2245 Changed the public key parameter to optional in the protocol
2246 specs so that empty OK reply can be sent. Affected file
2249 Added a message to Irssi SILC client to tell to user if the
2250 server did not return a public key.
2252 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2254 * Fixed a channel key regeneration bug. It registered new
2255 timeout tasks exponentially until all system resources were
2256 used. Affected file silcd/server.c.
2258 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Added the SILC Document generator to the scripts/silcdoc.
2261 It can be used to generate the Toolkit Reference Manual out
2262 of the source tree. Internally it will also use the RoboDoc
2263 generator now imported in util/robodoc.
2265 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Added couple of return's in rekey protocol if error orccurred
2268 during the protocol. The execution must be terminated.
2269 Affected file silcd/protocol.c. Also, terminate the protocol
2270 always with timeout.
2272 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * The client's Client ID was created initally from the wrong
2275 nickname (it could have been in format nick@host) in the
2276 silc_server_new_client. Affected file silcd/packet_receive.c
2278 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Added some SILC_LOG_ERROR's to various error conditions
2281 if client could not be added to ID cache. Affected files
2282 silcd/packet_receive.c and silcd/server.c.
2284 * When client's sock->user_data is freed, NULL also the
2285 client->router and client->connection pointers. Added check
2286 for these pointers being NULL to various places around the
2287 code. Affected file silcd/server.c.
2289 * Added client->data.registered == TRUE checks to various
2290 places around the code to assure that unregistered client's
2291 are not handled when it is not allowed. Affected file
2294 * Added `bool registered' fields to all
2295 silc_idlist_[server|client]_get_* routines to indicate whether
2296 the fetched client needs to be registered or not. Affected
2297 file silcd/idlist.[ch].
2299 * Add your own entry as registered to the ID cache in the
2300 server. Affected file server.c.
2302 * Fixed a bug in silc_server_new_server. The SilcServer was
2303 set as the new server's context instead of SilcServerEntry.
2304 This naturally caused some weird bugs.
2306 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Do not delete the channel rekey task when adding it
2309 for in silc_server_create_channel_key.
2311 * Changed the silc_server_create_channel_key to return
2312 TRUE or FALSE to indicate the success of the channel key
2315 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Fixed MSVC++ project files and added missing files to
2318 Makefiles under win32/.
2320 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Do not add TCP_NODELAY flag if the operating system
2323 does not have it defined. Affected files are
2324 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2326 * Fixed buffer overflow from Irssi SILC Client. Affected
2327 file irssi/src/fe-common/core/themes.c.
2329 * Fixed double free in client library in the file
2330 lib/silcclient/client.c when disconnecting from server.
2332 * Applied double free patch from cras to Irssi SILC client.
2333 Affected files irssi/src/core/[modules/expandos].c
2335 * Fixed the disconnection handling to Irssi SILC Client.
2336 The application must call silc_client_close_connection
2337 in ops->connect client operation in case of failure of
2338 the connection. Affected file is
2339 irssi/src/silc/core/client_ops.c.
2341 * Do not set sock->protocol to NULL in the function
2342 silc_client_close_connection after executing the protocol's
2343 final callback since the sock might not be valid anymore.
2344 Affected file lib/silcclient/client.c.
2346 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Do not enable SILC_THREADS if the linking with libpthread
2349 did not happen. Affected file configure.in.pre.
2351 * Added notion to protocol specification that server must
2352 verify the sent authentication payload with CMODE when
2353 setting the channel founder key. Implemented it to the
2354 server. Affected file silcd/command.c.
2356 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2358 * Added _EXTRA_DIST SILC distribution variable to the
2359 distributions file. It is used to conditionally add extra
2360 files or directories to the specific distribution. Affected
2361 files ./prepare, Makefile.am.pre and distributions.
2363 Removed the `_' from the start of the distribution names.
2366 * Added README.WIN32 for instructions to compile the Toolkit
2369 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Fixed a double free in disconnection in the server. Affected
2372 file is silcd/server.c.
2374 * Fixed the lib/silcske/groups.c to work now also with GMP
2375 MP library. The string conversion did not work when using
2376 specific base and the base is indicated in the string as well.
2378 * Created win32/ directory which now includes MSVC++ specific
2379 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2380 It will appear only in the toolkit distribution
2382 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Changed the key material distribution function in case when
2385 the hash output is too short. The data is now concatenated
2386 a bit differently than it used to. Made the change to the
2387 SKE protocol specification.
2389 * Added better GMP detection to configure.in.pre. A patch
2392 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Fixed a minor bug in SKE that might cause some problem on
2395 some platforms. Affected file lib/silcske/silcske.c.
2397 * Added the cookie checking for initiator in the SKE. It checks
2398 that the responder returns the sent cookie unmodified. The
2399 affected file is lib/silcske/silcske.c. Added new SKE
2400 error type INVALID_COOKIE that can be sent during the
2401 negotiation. Fixed some memory leaks as well.
2403 * Added the "invalid cookie" error message to Irssi SILC client's
2406 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Added `task_max' field to the SilcClientParams to indicate
2409 the maximum tasks the scheduler can handle. If set to zero,
2410 default values are used. Affected file lib/silcclient/silcapi.h.
2412 * Fixed memory leaks in silc_client_close_connection. Affected
2413 file lib/silcclient/client.c.
2415 * Added silc_client_del_client_entry to client library to free
2416 all memory of given client entry. Affected file is
2417 lib/silcclient/idlist.[ch].
2419 * Added new functions silc_client_del_channel and
2420 silc_client_del_server to delete channel and server entries.
2421 Affected file lib/silcclient/[silcapi.h/idlist.c].
2423 * Removed silc_client_del_client_by_id from silcapi.h.
2425 * Fixed the INFO command to return the server's own info
2426 correctly when querying by Server ID. Affected file is
2429 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Removed the non-blocking settings in WIN32 code in the
2432 silc_sock_[read/write] and added SleepEx instead. Affected
2433 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2434 of input data is now checked with FIONREAD and ioctlsocket.
2436 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Call silc_schedule_task_del_by_context in the
2439 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2440 Affected file lib/silccore/silcprotocol.c.
2442 * Call silc_protocol_cancel for active protocols in the
2443 silc_server_close_connection if the funtion
2444 silc_server_free_sock_user_data has not been called.
2445 Affected file silcd/server.c.
2447 * Generic tasks cannot be deleted using the del_by_fd
2448 task deleting function since generic tasks does not match
2449 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2451 * Added a notion to SILCOPER help file that the SILCOPER works
2452 only on router server, not on normal server.
2454 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Added for WIN32 support for the new scheduler as well.
2457 Affected file lib/silcutil/win32/silcwin32schedule.c.
2459 * Fixed the SHA1 implementation to work on various platforms.
2461 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2464 API. It is part of the scheduler now. Everything else is
2465 as previously but some functions has changed their names.
2466 Checkout the lib/silcutil/silcschedule.h for the interface.
2467 Updated all applications to use the new interface. Affected
2468 files are lib/silcutil/silcschedule.[ch].
2470 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Found a bug in the SKE implementation. The HASH value,
2473 specified by the protocol, was not computed correctly. The
2474 public key of the responder was not added to the computation
2475 even though it is mandatory. Affected file lib/silcske/silcske.c.
2476 This unfortunately causes incompatibilities with older
2477 clients and servers.
2479 * Added WIN32 specific network init and uninit functions:
2480 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2481 the Winsock2. Affected file lib/silcutil/silcnet.h and
2482 lib/silcutil/win32/silcwin32net.c.
2484 * Set the socket always to nonblocking mode on WIN32 after
2485 reading data or writing data. Affected file is
2486 lib/silcutil/win32/silcwin32sockconn.c.
2488 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Fixed various compilation problems under WIN32. Affected
2491 files lib/silcutil/win32/silcwin32thread.c and
2492 lib/silcutil/win32/silcwin32schedule.c.
2494 * Removed all _internal.h #includes from public header
2495 files. Internal headers must never be included from
2498 Removed also the lib/silcske/payload_internal.h file.
2500 * All include files that may be needed (public and some others
2501 included by the public headers) by application developers are
2502 now copied to the ./includes directory. It does not copy any
2503 internal headers. Affected file Makefile.defines.pre and all
2504 Makefile.am's under lib/ and subdirs.
2506 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Do not change the ~/.silc directory's permissions automatically.
2509 Affected file irssi/src/silc/core/clientutil.c.
2511 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Do not cancel the protocol in silc_server_close_connection
2514 it might cause recursion. Now cancelled in the function
2515 silc_server_free_sock_user_data. Affected file silcd/server.c.
2517 * Fixed the silc_server_remove_clients_by_server to regenerate
2518 the channel keys correctly finally. Added also new function
2519 silc_server_remove_clients_channels to actually do it.
2520 Affected file silcd/server.c.
2522 * Fixed the silc_server_new_channel to not crash by giving
2523 wrong router to the new channel. Affected file is
2524 silcd/packet_receive.c.
2526 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2529 which is given as argument to the silc_client_alloc now.
2530 It can be used to configure the client and set various parameters
2531 that affect the function of the client.
2533 * The USERS command in server did not check whether the channel
2534 is private or secret. Affected file silcd/command.c.
2536 * Added new argument to the USERS command in protocol specification.
2537 The USERS command now can take the channel name as argument
2538 as well. Added support for this in client and server and
2539 updated the protocol specs.
2541 * Completed the GETKEY command in client. It can be now used
2542 to fetch also servers public key not only some clients.
2543 Affected files lib/silcclient/command[_reply].c.
2545 * Added silc_client_get_server to return server entry by the
2546 server name. Affected files lib/silcclient/silcapi.h and
2549 * Redefined the IDENTIFY command in protocol specification to be
2550 more generic. It now can be used to query information about
2551 any entity in the SILC Network, including clients, servers and
2552 channels. The query may be based either the entity's name
2553 or the ID. Added support for this in both client and server.
2555 Affected files silcd/command.c and lib/silcclient/command.c
2556 and command_reply.c.
2558 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2559 the _from_client and _from_server functions. Affected file
2562 * Added silc_client_get_channel_by_id_resolve to the file
2563 lib/silcclient/silcapi.h to resolve channel information by
2564 its ID. Added also silc_client_get_channel_by_id that
2565 does not resolve it from the server.
2567 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Added SilcServerEntry context into the client library
2570 to represent one server. The INFO command now allocates
2571 these to save the resolved server info. For now on the
2572 client library will also keep information about servers,
2573 connected and resolved with INFO.
2575 The INFO command now allocates the SilcServerEntry context
2576 and saves the server info there. The COMMAND_REPLY in
2577 the INFO now returns the parameters to application in
2578 same order as defined in the protocol specification.
2580 The entries are cached in the client->server_cache.
2582 * The INFO command is now issued after received the Client ID
2583 from the server. Affected file lib/silcclient/client.c.
2585 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2586 to the application as the mode changer might be server.
2587 It is guaranteed that NULL is not returned anymore to the
2588 application. Affected file lib/silcclient/client_notify.c.
2590 The ID Type is now also passed to the application so that
2591 it can check whether the returned entry is SilcClientEntry
2594 Added new function silc_client_get_server_by_id to return
2595 the server entry by ID. Affected files are the
2596 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2598 * Do not create the channel in the Irssi SILC Client when issuing
2599 the JOIN command but when received the sucessful JOIN command
2600 reply. Otherwise the channel might get created even though we
2601 could not join it. The Affected file is
2602 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2604 * Fixed a channel joining bug in router. The router must also
2605 check the channel modes, invite and ban lists etc. when serving
2606 the JOIN command sent by normal server. Affected file is
2607 silcd/command.c. The router now resolves the client's
2608 information from the server who sent the JOIN command if it
2609 does not know it, and processes the JOIN command only after
2612 * Changed the SilcCommandCb to take new argument; void *context2.
2613 Affected file lib/silccore/silccommand.h
2615 The second argument in the command callbacks in the server now
2616 includes the SilcServerCommandReplyContext if the command was
2617 called as pending command callback from the command reply.
2618 Otherwise it is NULL. When called as pending the status of the
2619 command reply will be checked and if it was erronous the
2620 error will be sent to the original sender of the command.
2621 This way the client always receives the error messages even
2622 though the server was actually the one who received the error
2623 when it resent the command to router, for example. Affected
2624 files silcd/command[_reply].[ch].
2626 * Fixed sending WHOWAS command's error message to client if
2627 the requested client could not be found. It was missing.
2630 * Changed the CMODE and CUMODE commands reply arguments in the
2631 protocol specification. The Channel ID is now sent in both
2632 of the commands to identify the channel. Implemented this
2633 new feature to the client and server. Affected files
2634 lib/silcclient/command_reply.c and silcd/command.c.
2636 * Made better checks for invite and ban lists in the JOIN
2637 command in server. Affected file silcd/command.c.
2639 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * The server now performs the incoming host IP/DNS lookup
2642 using the silc_socket_host_lookup and thus does not block
2643 the server anymore. Affected file silcd/server.c.
2645 * Completed the multi-thread support for SILC Scheduler in
2646 the lib/silcutil/silcschedule.c.
2648 * Fixed the configure.in.pre to detect the pthread correctly
2651 * Fixed a deadlock in silc_task_queue_wakeup in the file
2652 lib/silcutil/silctask.c.
2654 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Added new function silc_schedule_wakeup that is used in
2657 multi-threaded environment to wakeup the main thread's
2658 schduler. It needs to be used when a thread adds a new task
2659 or removes a task from task queues. After waking up, the
2660 scheduler will detect the task queue changes. If threads
2661 support is not compiled in this function has no effect.
2662 Implemented the wakeup mechanism to both Unix and WIN32
2663 systems. Affected files are lib/silcutil/silcschedule.[ch],
2664 lib/silcutil/unix/silcunixschedule.c and the
2665 lib/silcutil/win32/silcwin32schedule.c.
2667 * Added new function silc_task_queue_wakeup to wakeup the
2668 scheduler by the specified task queue. Affected file
2669 lib/silcutil/silctask.[ch].
2671 * The silc_socket_host_lookup_start now wakes up the scheduler
2672 after adding the timeout task. Affected file is
2673 lib/silcutil/silcsockconn.c.
2675 * The silc_socket_host_lookup is synchronous now if the threads
2676 support is not compiled in. However, the callback is still
2677 called asyncronously through the scheduler, anyway. Affected
2678 file lib/silcutil/silcsockconn.c.
2680 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Added new function silc_socket_host_lookup to perform
2683 asynchronous IP and FQDN lookups for the socket connection.
2684 Affected files lib/silcutil/silcsockconn.[ch].
2686 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2689 that may or may not compile the mutex support in.
2691 Changed the silc_mutex_alloc interface. It allocates the
2692 mutex now to the sent pointer and returns TRUE or FALSE.
2694 Affected file lib/silcutil/silcmutex.h.
2696 * Wrote the SILC Task Queue interface to support multi-threads.
2697 Affected file lib/silcutil/silctask.[ch].
2699 * Wrote the SILC Scheduler to support multi-threads. Affected
2700 file lib/silcutil/silcschedule.c.
2702 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2705 in lib/silcutil/win32/.
2707 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Defined SILC Mutex API and SILC Thread API and implemented
2710 them for Unix. Affected files are
2711 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2712 lib/silcutil/unix/silcunixmutex.c and
2713 lib/silcutil/unix/silcunixthread.c.
2715 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Fixed the silc_server_remove_clients_by_server's channel
2718 key re-generation. The hash table handling was incorrect
2719 and would not work with many channels. Affected file is
2722 * Fixed some memory leaks around the server code.
2724 * Rewrote the silc_server_get_users_on_channel to support IPv6
2725 based Client ID's. Affected file silcd/server.c.
2727 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2728 specification. However, a separate document must be written
2729 to define the detailed signing procedure and the payload
2730 associated with the flag. Defined the flag to the
2731 lib/silccore/silcchannel.h as well.
2733 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Changed the dynamic tables to static size tables in the
2736 lib/silccrypt/silchmac.c.
2738 * Removed GCC dependencies from the code. A patch by cras.
2740 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Do not show the error "Error receiving packet bla bla"
2743 in server if it really was not an error (-2 means that reading
2744 is pending). Affected file silcd/server.c.
2746 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2748 * Fixed a possible crash in silc_server_remove_clients_by_server
2749 in silcd/server.c. Fixed there also some memory leaks.
2751 * Fixed the silc_idlist_replace_client_id. It could replace
2752 wrong key in the hash table. Affected file silcd/idlist.c.
2754 * Do not check whether there are global users on the channel
2755 if the channel->global_users is FALSE. Affected functions
2756 silc_server_remove_from_one_channel and
2757 silc_server_remove_from_channels in silcd/server.c. Also,
2758 do not check if the removed client is local as we can be
2759 sure that global client was not removed from the channel
2760 and checking for global users is not needed.
2762 * The silc_server_remove_clients_by_server now re-generates
2763 the channel keys correctly for those channels that had
2764 clients removed from them. Affected file silcd/server.c.
2766 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2768 * Found the reason of random crashes in the server. We weren't
2769 ignoring the SIGPIPE signal (which can be sent in write())
2770 and it crashed the server. Affected file silcd/silcd.c.
2772 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Assure that sock->user_data is not NULL in the function
2775 silc_server_packet_send in silcd/packet_send.c.
2777 * Disconnect the remote connection if it could not be added
2778 to any ID lists in the server. The affected file is
2781 * Check in silc_server_packet_send[_real/dest] that the
2782 socket is not disconnecting and ignore the data if it is.
2783 Affected file silcd/packet_send.c.
2785 * Define inline to __inline on native WIN32 compilation.
2786 Affected file includes/silcwin32.h.
2788 * Added some explicit type casts for inline code since MSVC
2789 require them. Affected files lib/silcutil/silcbuffer.h,
2790 lib/trq/silcdlist.h and lib/trq/silclist.h.
2792 * Print warning in log files from now on if the packet
2793 decryption fails. Affected file silcd/server.c.
2795 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Changed the `say' client operation's interface to accept
2798 new `type' argument to indicate the type of the message sent
2799 by the library. The application may filter the library's
2800 messages according the type. The affected file is the
2801 lib/silcclient/silcapi.h.
2803 * Added two new functions to lib/silcclient/silcapi.h:
2804 silc_client_del_client and silc_client_del_client_by_id.
2805 Affected file lib/silcclient/idlist.c.
2807 * Moved the clientincludes.h from includes/ to silc/ and
2808 serverincludes.h from includes/ to silcd/.
2810 * The modes for the CMODE and CUMODE are now passed as
2811 uint32 for application with COMMAND_REPLY. The affected
2812 file is lib/silcclient/command_reply.c.
2814 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * /WHOIS without arguments shows client's own information.
2817 Affected file lib/silcclient/command.c.
2819 * Changed PING to not accept any arguments. The specs
2820 says that client can ping only the connected server so
2821 requiring an argument is not needed. Affected file is
2822 lib/silcclient/command.c.
2824 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Fixed a fatal bug in private message sending and reception
2827 encryption and decryption when using private message keys.
2828 The implementation was incorrect and did not follow the
2829 specification. It causd that some of the message were
2830 lost since it did not use the sending and receiving keys
2831 as the protocol suggests. This has been fixed and will cause
2832 incompatibilities with older clients when sending private
2833 message encrypted with private message keys. Affected files
2834 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2835 and various other in Irssi SILC Client.
2837 Added `responder' boolean argument to the functions
2838 silc_client_add_private_message_key[_ske] to indicate when
2839 the key is added as responder or initiator of the key
2842 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Removed the silc_ske_check_version function and created
2845 a SilcSKECheckVersion callback. Added also a function
2846 silc_ske_set_callbacks that is now used to set all SKE
2847 callbacks. The callback functions are not given to
2848 the SKE functions anymore, but this function is used to
2851 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2853 * Added `silc_version' argument to the silc_client_alloc
2854 to define the version of the application for the library.
2855 The library will use the version string to compare it
2856 against the remote host's (usually a server) version
2857 string. Affected file lib/silcclient/silcapi.h
2859 * Added the KE protocol context to Key Agreement context
2860 in client library so that we can abort the SKE if it
2861 is in process when we get timeout. Affected file is
2862 lib/silcclient/client_keyagr.c.
2864 * Do not resolve the client ID forever if it returns in the
2865 first time that such client does not exist. This was done
2866 for example with private message. Affected file is
2867 lib/silcclient/client_prvmsg.c.
2869 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Do not add regex.h for WIN32. The affected file
2872 includes/silcincludes.h.
2874 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2875 not work yet 100%. It generates the DLL's automatically
2876 when compiling with --with-win32 under cygwin.
2878 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * lib/contrib/regex.c is not compiled on WIN32.
2882 * Added silc_net_get_socket_opt function to the
2883 lib/silcutil/silcnet.h.
2885 * Added includes/silcwin32.h for WIN32 specific includes
2888 * Do not use ptime structure or any of the posix process
2889 functions on WIN32 in lib/silccrypt/silrng.c.
2891 * Added silc_gettimeofday to provide generic function
2892 for struct timeval on all platforms. Added the function
2893 to lib/silcutil/silcutil.h.
2895 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2898 library as they clearly belong there. As a plus side we
2899 can make the actual socket connection routines platform
2902 Added also new generic function silc_socket_read and
2903 silc_socket_write (that used to be silc_packet_[read/write].
2904 The implementation of these are platform specific.
2906 * Added WIN32 specific routines of silc_socket_[read/write]
2907 to lib/silcutil/win32/silcwin32sockconn.c.
2909 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Added preliminary support for native WIN32 compilation under
2912 cygwin (using the -mno-cygwin option for GCC) to the
2913 ./configure.in.pre. The --with-win32 now prepares the
2914 compilation for native WIN32.
2916 * Rewrote the SILC Scheduler interface in the file
2917 lib/silcutil/silcschedule.h. The scheduler is now context
2918 based and does not have anymore any global static scheduler.
2919 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2920 and created lib/silcutil/win32 directory for WIN32 based
2923 * Added Unix specific network routines to the
2924 lib/silcutil/unix/silcunixnet.c and the old
2925 lib/silcutil/silcnet.c includes now only generic routines.
2927 Added WIN32 specific network routines to the
2928 lib/silcutil/win32/silcwin32net.c.
2930 * Added Unix specific utility functions from the
2931 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2933 * Added WIN32 SILC Scheduler to the file
2934 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2937 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Do not handle JOIN notify in the server if the target client
2940 is not registered (idata->registered == FALSE). The affected
2941 file is silcd/packet_receive.c.
2943 * Update the nickrec->founder in event_cumode in the Irssi SILC
2944 client. Affected file irssi/src/silc/core/silc-channels.c.
2946 * Fixed the CUMODE_CHANGE notify handling in the server when
2947 server and router are announcing their clients on channels.
2948 Now the mode changes are saved and notified correctly. The
2949 affected file is /silcd/packet_receive.c.
2951 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2952 They really did not replace the cache entry in the ID Cache.
2953 Now they do that. Affected file silcd/idlist.c.
2955 * Fixed the KICK notify handling in the Irssi SILC client to
2956 update the channel records so that the kicked client does not
2957 appear to be on the channel. The affected file is
2958 irssi/src/silc/core/silc-channels.c.
2960 * Always update the conn->current_channel when executing command
2961 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2963 * Fixed the KILL notify handling in Irssi SILC client to remove
2964 the killed client on all channels.
2966 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Fixed the silc_parse_command_line to remove extra spaces
2969 from the start and end of the arguments. Affected file is
2970 lib/silcutil/silcutil.c.
2972 * Cancel and free any active protocol in the function
2973 silc_server_close_connection. Affected file silcd/server.c.
2975 * Cancel and free any active protocol in the function
2976 silc_client_close_connction. Affected file is
2977 lib/silcclient/client.c.
2979 * Do not execute the KILL command for clients that are in
2980 history (ie. they are not in the network). Affected file is
2983 * Fixed KILL notify handling, client does not crash anymore.
2984 Affected file irssi/src/silc/core/silc-channels.c.
2986 * Reduced the default packet buffer size from 2048 to 1024 in
2987 lib/silccore/silcpacket.c.
2989 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2990 counter to the SKE context that is incresed when the SKE library
2991 performs async operation outside the library. If the outside
2992 process frees the SKE context and FREED status will be set
2993 and the library will detect after the sync operation that the
2994 libary is freed. The affected files are
2995 lib/silcske/silcske[_status].[ch].
2997 * Resolve the client entry information in the function
2998 silc_client_channel_message to assure that NULL pointer is not
2999 passed as client entry to the application. */
3001 * Fixed the task timeout calculation to assure that there is
3002 never negative timeouts. The affected file is
3003 lib/silcutil/silcschedule.c.
3005 * Fixed the channel user mode notification sending in server.
3006 It was sent point-to-point to the router (or to server by router)
3007 but it needs to be destined to a channel. The routines now
3008 supports sending the channel user mode notifys to the channels
3009 when announcing clients and channels. Affected files are
3010 silcd/server.c and silcd/packet_receive.c.
3012 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3013 It did not actually replace the old channel entry in the cache.
3014 Affected file lib/silcclient/client_notify.c.
3016 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Fixed a possible crash in silc_packet_send_prepare. It now
3019 assures always that there is enough space in the buffer and
3020 at the tail area of the buffer (for MAC).
3022 Fixed the inbound buffer reallocation in silc_packet_read.
3023 It was old code and did not handle the reallocation correctly.
3026 The affected file is lib/silccore/silcpacket.c.
3028 * Fixed buffer overflow in silc_parse_nickname in the file
3029 lib/silcutil/silcutil.c.
3031 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * make install generates new server keys only if there is not
3036 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3039 Added check that if the NOREPLY is set then we will not send
3040 the away message. This avoids infinite loop of away messages
3041 if both clients are away. The affected file is
3042 lib/silcclient/client_prvmsg.c.
3044 * Fixed client crash if /NICK was given without arguments.
3045 Affected file lib/silcclient/command.c.
3047 * Server does not send the invite list in INVITE command back
3048 to the client if the list was not altered. Added this notion
3049 to the protocol spec as well. Affected file silcd/command.c.
3051 Fixed possible crash in INVITE command by checking the
3052 value of silc_server_get_client_route command.
3054 * Fixed the INVITE notify type handling. The arguments are now
3055 taken in correct order and client does not crash. The affected
3056 file is irssi/src/silc/core/silc-channels.c.
3058 Removed the "Inviting xxx to channel" message from the
3059 client library away and let the application handle it.
3060 Affected file lib/silcclient/command.c. Added that message
3061 to Irssi SILC client's message formats.
3063 * Fixed CMODE command crash in client. It now checks the
3064 amount of arguments correctly and does not crash. The affected
3065 file is lib/silcclient/command.c.
3067 * Do not create new channel automatically in silc_channels_join
3068 but check whether the channel by that name already exists.
3069 Affected file irssi/silc/core/silc-channels.c.
3071 * Do not send the SERVER_SIGNOFF to router if the disconnected
3072 entity was the router. Affected file silcd/server.c.
3074 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3075 SILC client as it was missing from there.
3077 Added the handling of the KICK notify to the Irssi SILC client
3078 as it was missing. Added "you have been kicked" message to
3079 Irssi SILC client's message modules formats.
3081 Added the handing of the KILL notify to the Irssi SILC client
3082 as it was missing. Added the kill message module formats
3085 The affected file is irssi/src/silc/core/silc-channels.c.
3087 * The router did not save the channel mode the server announced.
3088 Affected file silcd/packet_receive.c.
3090 * Fixed a possible crash in INFO command in server. If the
3091 server did not provide the server info it crashed. Affected
3092 file silcd/command.c.
3094 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Fixed the GETKEY command in the server to check also the
3097 global list. Otherwise the GETKEY would not work correctly
3098 in normal SILC server. Affected file silcd/command.c.
3100 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Fixed GETKEY crash, it crashed if the command did not succseed.
3104 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3107 is now real and not just an macro interface to GMP.
3109 Removed the entire GMP from the source tree and imported new
3110 NSS MPI library instead. Reason for removing GMP is that it is
3111 extremely large and compiles extremely slow. The NSS MPI
3112 is only a few files and compiles in less than 10 seconds.
3113 The speed is also about the same as GMP. The MPI is imported
3114 to lib/silcmath/mpi.
3116 If the system has GMP installed we will still use the GMP.
3117 If it is not then the NSS MPI will be compiled.
3119 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Merged a long nickname (127 characters long) crash bugfix from
3122 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3124 * Merged a freed memory reference bugfix from Irssi CVS tree.
3125 Affected file irssi/src/core/commands.c.
3127 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Added the server's public key sving and verification to the
3130 server when performing the SKE. This was missing and the
3131 remote server's (or router's) public key was accepted without
3132 checking whether we have it previously or trust it at all.
3133 Affected file silcd/protocol.c.
3135 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Check in the silc_server_timeout_remote if protocol is active
3138 and make sure that the protocol's final callback is called so
3139 that all memory if freed. Affected file silcd/server.c.
3141 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * silc_server_whois_send_reply crashed the server if the nickname
3144 was 127 characters long. Affected file silcd/command.c.
3146 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Added sanity check to the silc_server_new_client. If the hostname
3149 is provided inside username then check that the provided hostname
3150 really is the same as the resolved one. If the hostname was not
3151 resolved then check it from the public key. Affected file is
3152 silcd/packet_receive.c.
3154 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3155 if the server disconnected us and the connection is not valid
3156 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3158 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3159 the library to the lib/silcutil/silcutil.[ch].
3161 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Close log file after open. Affected file
3164 lib/silcutil/silclog.c.
3166 * Check whether sock == NULL in silc_client_send_packet and return
3167 if it is. Affected file lib/silcclient/silcclient.c.
3169 * Check rec->entry == NULL in the Irssi SILC Client before
3170 sending the channel message. Affecte file is
3171 irssi/src/silc/core/silc-servers.c.
3173 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Merged a splitted window bugfix from Irssi CVS tree. The
3176 affected file is irssi/src/fe-text/textbuffer-view.c.
3178 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3179 It did not print nickname.
3181 * Improved the distributions system a bit.
3183 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3186 irssi/src/fe-text/gui-window.c.
3188 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3189 to in-active server. The affected file is
3190 irssi/src/silc/core/client_ops.c.
3192 * Resolve the client in USERS command reply if the entry does
3193 not have username resolved. The affected file is
3194 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3195 command to WHOIS command to really resolve stuff. The USERS
3196 is not used any more in any critical section so WHOIS can
3197 be used even though it might be slower than IDENTIFY.
3199 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3202 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Changed the protocol API a bit more consistent in the
3205 lib/silccore/silcprotocol.[ch].
3207 * Changed the following headers to ROBODoc format:
3209 lib/silccore/silcpayload.h
3210 lib/silccore/silcprotocol.h
3211 lib/silccore/silcsockconn.h
3213 All core library headers are now formatted.
3215 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Fixed a bug in Irssi SILC client; do not show that you are
3218 server/router operator if you really are not. Affected file is
3219 irssi/src/silc/core/client_ops.c.
3221 * Renamed silc_command_free_payload to silc_command_payload_free.
3222 Affected file lib/silccore/silccommand.h
3224 * Added silcmath.h to include the prototoypes of various routines
3225 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3228 * Changed the following headers to ROBODoc format:
3230 lib/silccore/silcchannel.h
3231 lib/silccore/silccommand.h
3232 lib/silccore/silcid.h
3233 lib/silccore/silcidcache.h
3234 lib/silccore/silcmode.h
3235 lib/silccore/silcnotify.h
3236 lib/silccore/silcpacket.h
3237 lib/silcmath/silcmath.h
3239 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Added checking to the server code not to start the server if
3242 ciphers and stuff are not configured properly. Affected files
3243 silcd/serverconfig.[h] and silcd/server.c.
3245 * Changed the layout of the header files of the public interfaces
3246 in the SILC libraries. The new layout supports ROBODoc
3247 documentation tool (and some others) so that it is easy to create
3248 a library reference manual. All the other headers and source
3249 code must still follow the CodingStyle document. Also source
3250 code must not include these ROBODoc stuffs, only the headers.
3251 Furthermore, all public interface headers must now be named
3252 by using `silc' prefix, example: silcapi.h, silccipher.h.
3253 Some files were renamed due to this. All the other headers
3254 must not be used as public interfaces. I will update the
3255 CodingStyle document later. Changed following headers, so far:
3257 lib/silcclient/silcapi.h
3258 lib/silccore/silcauth.h
3259 lib/silccore/silcprivate.h
3260 lib/silccrypt/silcdh.h
3262 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Removed silc_client_packet_send_flush from the client library
3267 as it is not needed. Affected file lib/silcclient/client.[ch].
3269 * Added printing of message of unresolved authentication method
3270 to the Irssi SILC client. Added it to the module formats.
3271 Removed the same message from the client library.
3273 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Added new distribution feature, DISTLABEL. Every distribution
3276 can define own preprocessor label that can be used in the
3277 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3278 file distributions, acconfig.h.pre and prepare.
3280 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Added Makefile.defines_int to include the actual definitions
3283 for Makefile.defines.in. Tested the new distribution system,
3284 created distributions and tested installation.
3286 * Added AWAY message printing to the Irssi SILC client. Added
3287 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3289 * Added SCONNECT command to call the SILC's CONNECT command.
3290 Cannot use CONNECT directly since Irssi uses that internally.
3291 Affected file irssi/src/silc/core/silc-servers.c.
3293 Added ACTION local command. It is same as ME command but takes
3294 the channel as mandatory argument.
3296 Rewrote some of the Irssi's help files to suite for SILC
3299 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Added Makefile.defines[.in] that should for now on be included
3302 in all Makefile.am file in the source tree. That file includes
3303 all common compilation definitions for SILC source tree.
3305 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Minor changes to the ./prepare script to change the package
3308 name according the distribution name to the configure.in.
3310 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Created new distribution system. Added file `distributions'
3313 that defines all the distributions that can be created out of
3314 the SILC source tree. The ./prepare script now reads that
3315 file to determine how to prepare the distributions. The
3316 first argument to the ./prepare is the name of the distribution
3317 and second is the version of the distribution. If given
3318 without arguments it creates the default (toolkit) distribution
3319 with the default version (defined in ./prepare).
3321 All Makefile.am files that are subject to the distributions
3322 are now named as Makefile.am.pre. These are ./Makefile.am
3323 and lib/Makefile.am. Others may be changed later.
3325 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Added invite list, ban list, some key management and connection
3328 error message printing to module formats in the Irssi SILC client.
3330 * Added new silc_client_set_away_message to set the away message
3331 that is back to the person who sent private message. The
3332 affected file lib/silcclient/silcapi.h and the
3333 lib/silcclient/client_prvmsg.c.
3335 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Fixed the private message sending in the Irssi SILC client,
3338 added local command KEY to the Irssi SILC client.
3340 Added key management and key agreement message formats to the
3341 irssi/src/fe-common/silc/module-formats.[ch].
3343 Added USERS (alias WHO) printing, server/router operator
3344 indication and LIST command printing to the module formats.
3346 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Fixed channel joining notify handling, cumode notify handling
3349 from Irssi SILC client.
3351 * Added SILC specific module-formats to the Irssi SILC client so
3352 that SILC specific message hilighting, colors etc is possible.
3353 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3355 Added channel mode, channel user mode, actions, notices,
3356 whois and whowas printing to the the module-formats.c.
3358 * Fixed a bug in channel deletion in the server. The channel
3359 is not left to the cache even if the channel founder auth mode
3360 is set when there are no users anymore on the channel. Affected
3361 file silcd/server.c.
3363 * The silc_net_localhost now resolves the entire hostname including
3364 the domain name. Affected file lib/silcutil/silcnet.c.
3366 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Changed the ask_passphrase client operation to be ascynchronous.
3369 It has now a completion callback and a context that the
3370 application must call after it has got the passphrase from
3371 the user. Affected files lib/silcclient/silcapi.h,
3372 lib/silcclient/protocol.c, lib/silcclient/command.c and
3375 Added SilcAskPassphrase callback that the application calls
3376 to deliver the passphrase to the library.
3378 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3379 The public key verification and especially a certificate
3380 verification is asynchronous procedure.
3382 Added new SILC_SKE_STATUS_PENDING status to indicate the
3383 request is pending and a callback will be called to finalize
3386 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3387 indicate that remote end did not send its public key (or
3388 certificate), even though we require it. Added check for this
3389 condition in the SKE. This was a security bug, now fixed.
3391 Defined new SilcSKEVerifyCbCompletion callback that is called
3392 when the verification process is completed.
3394 The affected files lib/silcske/silcske_status.h and
3395 lib/silcske/silcske.[ch].
3397 * Changed the verify_public_key client operation to be async
3398 as well. Defined SilcVerifyPublicKey callback that is used to
3399 indicate the success of the public key verification process.
3401 Changed the server and client to use the new async client
3404 * Changed the Irssi SILC client's internal scheduler to be called
3405 twice as many times as it used to be. As a result the client
3406 should be a bit faster now. Affected file is
3407 irssi/src/silc/core/silc-core.c.
3409 * Added support to Irssi SILC client of asynchronous public key
3410 verification and passphrase inquiry. Affected file is
3411 irssi/src/silc/core/silc-core.c.
3413 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Do not say "You have left channel %s" in client library.
3416 Moved it to the application. Affected files are
3417 lib/silcclient/command.c and silc/client_ops.c.
3419 * Fixed silc_client_get_clients. Command context was not
3420 duplicated and was freed memory in the callback. Affected
3421 file lib/silcclient/idlist.c.
3423 * Do not say "you are now talking..." on JOIN command in the
3424 client library. The appliation must handle it.
3426 * Do not say ".. changed topic to" in command reply in the
3427 client libary. The application must handle it.
3429 * Fixed TOPIC command sending in the client library.
3431 * Fixed a memory leak in silc_client_command_free in the file
3432 lib/silcclient/command.c.
3434 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Imported a modified version of Irssi client to the source tree.
3437 The Irssi will be used to create a new client called
3438 Irssi SILC. Imported to irssi/.
3440 Added silc_core_init_finish function to the Irssi. Affected
3441 file irssi/configure.in.
3443 A lot changes in the Makefile.ams around the irssi tree.
3445 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Do not rehash if the new size is same as the old size of the
3448 hash table, in the silc_hash_table_rehash*. The affected file
3449 lib/silcutil/silchashtable.c.
3451 * Replaced hash_table_del_by_context calls from the server
3452 (when channel->user_list and client->channels) to the
3453 hash_table_del as it is sufficient and faster.
3455 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added silc_hash_table_list, silc_hash_table_get and the
3458 SilcHashTableList structure to provide an alternative way to
3459 traverse the hash table. The affected files are
3460 lib/silcutil/silchashtable.[ch].
3462 * Changed the server's idlist routines to use the hash table
3463 routines to optimize the code.
3465 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Replaced the client entry's `channel' list and channel entry's
3468 `user_list' list to hash tables for optimized lookup. Changed
3469 the code to use the hash table interface around the code.
3470 Affected file lib/silcd/idlist.[ch].
3472 * Added `auto_rehash' boolean argument to the function
3473 silc_hash_table_alloc to indicate whether the hash table should
3474 auto-rehash when it thinks is appropriate time. It will
3475 increase the hash table size if the there is twice as much
3476 entries in the table than the size of the table, and will
3477 decrease the size if there are twice as less entries than
3478 the size of the table.
3480 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3484 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * silc_idcache_purge_by_context deletes the entry now by context
3487 as it is supposed to do. Affected file lib/silccore/idcache.c.
3489 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3490 client is not anymore valid (WHOWAS givens the info) and not
3491 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3493 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Removed the `data' and `data_len' arguments from the ID Cache
3496 interfaces and added `name' argument. ID Cache does not handle
3497 anymore the binary data only a names associated with given ID.
3499 * When hashing a Client ID with silc_hash_id the entire ID is
3500 not hashed anymore, instead only the hash of the Client ID is
3501 hashed. This way we can access the Client ID from the cache
3502 with Client ID but with the hash of the ID (which is a hash of
3503 the nickname) as well without any difference in performance.
3505 Added also silc_idcache_find_by_id_one_ext to do one on one
3506 searching when we have the actual ID. Added also function
3507 silc_hash_client_id_compare. The affected files are
3508 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3510 * When hashing the name associated with a ID it is always done
3511 in lowercase. This way we can access the cache without worrying
3512 about case-sensitivity, even though, for example nicknames are
3515 * Fixed a bug in server with channel message sending. It put
3516 wrong ID type as destination ID. The affected file
3517 silcd/packet_send.c.
3519 * silc_idcache_del_by_context now deletes from all hash tables
3520 by context. Affected file lib/silccore/idcache.c.
3522 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Changed the client library to use the new ID Cache interface.
3525 Changes around the source tree.
3527 * Added silc_hash_table_rehash_ext to rehash with specific
3528 hash function. Affected file lib/silcutil/silchashtable.[ch].
3530 * Added silc_hash_string_compare to compare two strings in the
3531 hash table. Affected file lib/silcutil/silcutil.[ch].
3533 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Added new function silc_idcache_del_by_context into the
3536 lib/silccore/idcache.[ch].
3538 * Changed the server's ID list routines to use the new ID Cache
3539 interface. Changes around the source tree.
3541 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Added silc_hash_table_del[_by_context]_ext functions in to the
3544 lib/silcutil/silchashtable.[ch].
3546 Removed silc_hash_table_find_all* routines and added new
3547 silc_hash_table_find_foreach to replace them.
3549 Added silc_hash_table_replace_ext function as extended
3550 replacing function. Separated the simple hash table interface
3551 from the extended hash table interface in the file
3552 lib/silcutil/silchashtable.h.
3554 * Fixed minor bugs and changed it to use some of the new
3555 hash table functions in lib/silccore/idcache.c
3557 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3559 * Added new function silc_hash_table_find_all to return all keys
3560 in the hash table by the specified key. As the hash table is
3561 collision resistant it also makes it possible to have several
3562 duplicate keys in the hash table. This function may be used to
3563 find all of the keys from the hash.
3565 Added user_context arguments to the SilcHashFunction,
3566 SilcHashCompare and SilcHashDestructor to deliver user specified
3569 Added new fuctions silc_hash_table_find[_all]_ext to do
3570 extended lookup with specified hash and compare functions and
3571 specified user contexts.
3573 Added new function silc_hash_table_add_ext to add the key
3574 with specified hash function and user context.
3576 Added new function silc_hash_table_foreach to traverse all
3577 entrys in the hash table. Added SilcHashForeach callback
3580 Added new function silc_hash_table_del_by_context to delete
3581 the entry only if the context associated with the key matches.
3583 Affected files are lib/silcutil/silchashtable.[ch].
3585 * Removed silc_hash_[server/client/channel]_id and added just
3586 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3587 silc_hash_id_compare to compare two ID's using as the hash table
3588 comparison function. Added also silc_hash_data to hash
3589 binary data and silc_hash_data_compare to compare it.
3591 * Removed silc_idlist_find_client_by_hash as it is not needed
3592 anymore. Affected file silcd/idlist.[ch].
3594 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3595 to use internally the SilcHashTable. The new ID Cache is a lot
3596 faster than the old one. Some of the ID Cache interface was also
3597 rewritten and obsolete and stupid functions were removed.
3599 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Added entry_count field to the SilcHashTable to keep the number
3602 of the entries in the table. Implemented the function
3603 silc_hash_table_rehash. Added new function
3604 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3606 Fixed a minor bug in silc_hash_table_free.
3608 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3609 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3610 into the lib/silcutil/silcutil.[ch].
3612 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Implemented a collision resistant hash table into the
3615 lib/silcutil/silchashtable[ch]. See the header and the source
3616 for the SilcHashTable API.
3618 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Merged dotconf version 1.0.2 into lib/dotconf.
3622 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Do not compile anything in lib/silcsim/* if the SIM support
3625 is not enabled. The tree should now compile without problems
3628 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Compiled the SILC under cygwin. Compiled and tested briefly
3631 without problems. More tests needed. The SIMs didn't compile
3634 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3636 * Fixed possible crash in silc_get_username in the
3637 lib/silcutil/silcutil.c.
3639 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Fixed a va_arg in silc/client_ops.c.
3643 * Oops, RC5 routines were named AES and caused some problems
3644 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3646 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added new SilcIDIP structure into the lib/silccore/id.h and
3649 replaced the old `ip' fields from all SILC ID's to that type.
3650 This is a step towards IPv6 support.
3652 The silc_id_get_len takes now the ID as an extra argument.
3653 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3654 both IPv4 and IPv6 based ID's.
3656 The affected files are lib/silccore/id.[ch] and other files
3657 around the tree using these routines.
3659 * Removed the ID length arguments in server from various
3660 silc_server_send_notify_* routines -> they are not needed
3663 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Fixed memory leak in silc_encode_pem_file in the file
3666 lib/silcutil/silcutil.c.
3668 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Check minor version as well in the SKE. Affected files are
3671 silcd/protocol.c and lib/silcclient/protocol.c.
3673 * Added --identifier option to the server so that an identifier
3674 can be when creating the public key for the server. Affected
3675 file is silcd/silcd.c.
3677 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3678 lib/silccrypt/silcpkcs.c.
3680 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Register default ciphers and stuff when using -C option with
3683 the server. Affected file sildc/silcd.c.
3685 * Put back the servers public key filename format, it is better
3686 than the new one. For now, the client keys are saved with the
3687 new filename format. The affected file silc/client_ops.c.
3689 * Implemented the Cipher API for the rest of the ciphers that
3690 did not implement it or implemented it the wrong way.
3692 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Register default ciphers and stuff when using the -S option
3695 in the client. Affected file silc/silc.c. Same also when
3696 creating new key pair with -C option.
3698 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Fixed the silc_verify_public_key client operation function to
3701 save the public keys differently. The fingerprint is now
3702 used as filename and not the hostname. This way also the
3703 client keys are saved uniquely and not with hostnames. The
3704 affected file is silc/client_ops.c.
3706 * Trimmed the silc_hash_fingerprint function to remove extra
3707 whitespaces from the end of the fingerprint. The affected
3708 file is lib/silccrypt/silchash.c.
3712 * Added silc_cipher_register_default function to register all
3713 default ciphers. It can be used when configuration files
3714 does not exist and the application does not want any specific
3715 ciphers in any specific order.
3717 The SilcDList is now used as silc_cipher_list dynamically
3718 allocated cipher list. Removed the static list all together
3719 and now all ciphers must be allocated to the dynamic list.
3720 The silc_cipher_alloc routine was changed to check only the
3723 All silc_cipher_* routines that used to return int returns
3726 The affected files lib/silccrypt/silccrypt.[ch].
3728 * The same thing was done to silc_hash_* as for silc_cipher_*
3729 routines. Affected files lib/silccrypt/silchash.[ch].
3731 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3732 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3733 Added also silc_pkcs_[un]register[_default] functions.
3734 Removed the data_context from the PKCS API.
3736 * Added silc_hmac_register_default function to register default
3737 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3738 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3739 to unregister all hmacs at once.
3741 * Register the default ciphers, hash functions, PKCSs and HMACs
3742 if client's configuration file does not exist. The affected
3745 * The client did not load the hash functions from the SIM
3746 modules at all. Added support for this. Affected file is
3747 silc/clientconfig.c.
3749 * When decoding public key with silc_pkcs_public_key_decode, check
3750 the supported algorithm only if PKCS are registered. Affected
3751 file lib/silccrypt/silcpkcs.c. The same was done with the
3752 silc_pkcs_private_key_decode.
3754 * Fixed the SILC List routines to keep the list always in order.
3755 It used to change the list's order when traversing the list but
3756 not it preserves the order. Affected file lib/trq/silclist.h.
3758 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Added the client library to use the SilcSocketConnection's
3761 reference counter (by silc_socket_dup) to prevent the bug that
3762 the socket object may be freed underneath async operation.
3764 * The name resolv library checking fixes in the configure.in.pre.
3767 * Created new version of the protocol drafts for future
3768 development. The -03 drafts are the ones that will be changed
3769 in the trunk now and the -02 will remain as they are.
3771 * Send list of CUMODE notifys to the router when announcing
3772 the channel users to the router. Affected file silcd/server.c.
3773 If the router receiving channel founder CUMODE for a channel
3774 that already has channel founder it will send CUMODE notify
3775 to the sender to remove the channel founder rights from the
3776 announced client. Affected file silcd/packet_receive.c.
3778 * The CUMODE notify may now use Server ID as well as the entity
3779 who changes the mode. Updated protocool specs.
3781 * Updated INSTALL and README files.
3783 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * New web pages in the http://silc.pspt.fi. The pages was
3790 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Implemented the [DenyConnectin] config section in the server.
3793 Added silc_server_config_denied_conn to check whether incoming
3794 connection is denied. Affected file silcd/serverconfig.[ch].
3796 * Do not check the ports when checking the incoming configuration
3797 data if the port is 0, meaning any. Affected file is
3798 silcd/serverconfig.c.
3800 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * Fixed buffer overflow in silc_string_compare in the file
3803 lib/silcutil/silcutil.c.
3805 * Fixed double free in silc_server_command_leave in the file
3808 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Fixed the version checking in the server. Affected file is
3813 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Fixed the configuration data fetching when accepting new
3816 connections in the server. Affected file silcd/server.c.
3818 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Added `sender_entry' argument to the function
3821 silc_server_packet_relay_to_channel so that we can check
3822 whether some destination actually belongs to the same route
3823 the sender belongs (ie, we must not resend the packet to the
3824 sender). Affected file silcd/packet_send.[ch].
3826 * Added `servername' field to the SilcClientEntry in the server
3827 to hold the name of the server where client is from. Affected
3828 file is silcd/idlist.h.
3830 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Moved the channel message encrypting in the router betwen
3833 router connections from silc_server_channel_message to the
3834 silc_server_packet_relay_to_channel since we want to check
3835 whether we have anybody channel before encrypting anything.
3836 Affected files silcd/packet_[receive/send].c.
3838 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Fixed the [AdminConnection] server config section to support
3841 multiple entries. Affected file silcd/serverconfig.c.
3843 * Added support into the server to check the validity of the
3844 incoming connection before executing any KE or authentication
3847 * The connection configuration is now saved to the KE and
3848 connection auth protocol contexts and not fetched anymore in
3849 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3851 * The local hosts listenning address and port is also resolved
3852 now when starting the server. We want to have the socket object
3853 to include the real address and port for the listener. Added
3854 new function silc_net_check_local_by_sock into the files
3855 lib/silcutil/silcnet.[ch].
3857 * Fixed a broadcast bug in server -> do not broadcast if we
3860 * Fixed a routing bug. Do not route broadcast packets ever.
3861 Broadcast packets must be processed always and not routed since
3862 they may be destined to some other host than yourself and thus
3863 would get routed without no good reason. Affected file is
3866 * Added function silc_server_config_is_primary_route to check
3867 whether primary router connection has been configured (a router
3868 configuration that we are initiating). If there is not, we
3869 will assume that there is only two routers in the SILC network
3870 and we will use the incoming router connection as our primary
3871 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3873 * Changed the order of the broadcasting. Broadcast _after_ the
3874 packet has been processed not before. Affected file is
3877 * Fixed a [ClientConnection] parsing bug. The port was never
3878 parsed correctly thus resulting to port 0. Affected file
3879 silcd/serverconfig.c.
3881 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3882 argument and did not set the broadcast packet flag. Affected
3883 file silcd/packet_send.c. Fixed same bug in the function
3884 silc_server_send_notify as well.
3886 * If we receive NEW_ID packet for our own ID in the server, ignore
3889 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Removed the nickname from the Private Message Payload.
3894 Updated the code and the protocol specs.
3896 * Updated protocol specs for submitting to the IETF.
3898 * Tweaked the Random Number Generator a bit. Affected file
3899 lib/silccrypt/silcrng.c. Exported a new function
3900 silc_rng_[global]_add_noise which can be used to add more
3903 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Do not parse packets with different timeout when protocol
3906 is active -> may cause problem with rekey. Affected file
3909 * When server receives signoff notify it must not create
3910 new channel key if the client is on any channels since the
3911 sender of the signoff notify will create it.
3913 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Added printing of error messages during SKE protocol from the
3916 failure packet sent by server during SKE. Affected file
3919 * Removed the client's failure_callback handling with timeout
3920 and handle it immediately when received.
3922 * The SKE library returned wrong type in SUCCESS and FAILURE
3923 packets. They must be 32 bit MSB not 16 bit MSB.
3925 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Ok, rewrote the logic of the re-key and now it seems to work.
3928 I tested it on high traffic with frequent re-keys without
3929 problems. Added hmac_receive (and renamed hmac to hmac_send)
3930 in SilcClientConnection in lib/silcclient/client.h and
3931 in SilcIDListData in silcd/idlist.h. Also, removed the
3932 SilcPacketParserContext's cipher and hmac fields as they are
3933 not needed anymore and actually caused some problems when
3934 the ciphers and hmac's changed underneath the packet parser.
3936 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * If re-key protocol is active then process the incoming packets
3939 synchronously since we must assure that icoming packets encrypted
3940 with the old key is processed before the new keys is set to
3941 use. This is true other packets than for REKEY packets.
3942 Affected file silcd/server.c. The same was done to client library
3943 as well, affected file lib/silcclient/client.c.
3945 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Fixed bug in client and server to accept the force send if
3948 the packet is send from silc_[server/client]_packet_process
3949 function. Otherwise the packets are never delivered, oops.
3951 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Disable force sending of packets when REKEY protocol is active.
3954 We must assure that no packet is sent directly when rekey is
3955 performed. All packets must be sent through packet queue.
3956 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3957 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3958 function is silc_[server/client]_packet_send_real to check
3961 * Replaced the SIM paths from example config files to
3962 /usr/local/modules. Also, make install creates now
3963 /usr/local/silc/logs directory to hold all the SILC server
3966 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Made the configure.in.pre work on Solaris. Patch by salo.
3970 * Made all ciphers compatible with non-x86 machines. Defined
3971 CBC mode macros into lib/silccrypt/ciphers_def.h.
3973 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Fixed the make install.
3977 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * When MAC computation fails the silc_packet_decrypt returned 0
3980 even though it was supposed to return -1. Fixed this. The
3981 affected file is lib/silccore/silcpacket.c.
3983 * Do not replace the config files in /etc/silc (in make install)
3984 if they already exist. Affected file ./Makefile.am.
3986 * Do not send re-key packets immediately but through packet queue.
3987 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3989 * Changed silc_net_check_host_by_sock to return FALSE if the
3990 IP/DNS could not be resolved. Though, it returns the IP address
3991 now even if it could not resolve it (but returns also FALSE).
3992 Affected file lib/silcutil/silcnet.[ch].
3994 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Added silc_pkcs_decode_identifier to decode the public key's
3997 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3998 Added also silc_pkcs_free_identifier. Added also new context
3999 SilcPublicKeyIdentifier.
4001 * Added -S option to the silc client. It is used to dump the
4002 contents of the specified public key file.
4004 * Changed the PKCS api to return the public key length when
4005 setting the public key.
4007 * Fixed a fatal bug in the public and private key file loading.
4008 Affected file lib/silccrypt/silcpkcs.c.
4010 * Execute the packet parsing for client with zero (0) timeout
4011 if the protocol is active. Affected file silcd/server.c.
4013 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Made the key generation options to the silcd program. Added
4016 -C option, equivalent to client's option.
4018 * Added new [ServerKeys] config section to the server. It
4019 configures the server's public and private key.
4021 * Defined generic Public Key Payload into the protocol
4022 specification to send specific type of public keys and
4025 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4026 public key or certificate.
4028 * Implemented the GETKEY command to the server and to the
4029 client library and on user interface.
4031 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Made preliminary `make install' work.
4035 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Added SilcServerRekey context into silcd/idlist.h.
4039 * Added the PFS support as defined in the specification to the
4040 SKE protocol. Affected files lib/silcske/*.c.
4042 * Added `ske_group' field to the SilcServerRekey context to hold
4043 the number of the SKE group that is used with PFS in re-key.
4044 Affected file silcd/idlist.h.
4046 * Added PFS re-key support to the server. Affected file is
4049 * Added silc_protocol_cancel to cancel execution of the next
4050 state of the protocol. Affected file is
4051 lib/silccore/silcprotocol.[ch].
4053 * Added the re-key support with and without PFS to the client
4054 library. Re-key is performed once in an hour, by default.
4056 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4057 Added silc_client_rekey_callback and silc_client_rekey_final.
4058 Affected files are lib/silcclient/protocol.[ch] and
4059 lib/silcclient/client.[ch].
4061 * Removed the `hmac_key' and `hmac_key_len' fields from the
4062 SilcClientConnection structure; not needed. Affected file is
4063 lib/silcclient/client.h.
4067 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Do not ask whether user wants to use the negotiated private key
4070 for private messages, just use it. Affected file is
4071 silc/local_command.c.
4073 * Added `send_enc_key' and `enc_key_len' fields to the
4074 SilcIDListData structure since they are needed in the re-key
4075 phase. Affected file is silcd/idlist.[ch].
4077 * Implemented the simple re-key protocol into the server.
4078 Affected files silcd/server.c and silcd/protocol.[ch]. The
4079 re-key will be performed once in an hour, by default.
4081 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4082 Added silc_server_rekey, silc_server_rekey_callback and
4083 silc_server_rekey_final.
4085 * Removed Tunneled flag from the protocol. Updated the code
4086 and the specifications.
4088 * Adde `pfs' field to the SilcIDListData to indicate whether
4089 the PFS is to be performed in the re-key. Affected file is
4092 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4095 int64 of at least the xintXX size. If void * is less that 4
4096 bytes uint32 * will be used. Defined bool as boolean.
4098 * Changed _ALL_ unsigned long and unsigned int to uint32,
4099 unsgined short to uint16 in the source tree.
4101 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4102 not handle clients that has entry->data.registered == FALSE.
4103 They are not in the network anymore. Affected file is
4106 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Implemented the sending of the SERVER_SIGNOFF notify in the
4109 server. Affected file is silcd/server.c.
4111 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4112 Added also silc_notify_payload_encode_args into the
4113 lib/silccore/silcnotify.[ch].
4115 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4116 Affected file silcd/packet_receive.c.
4118 * Implemented the SERVER_SIGNOFF notify handling in the client
4119 library. Affected file lib/silcclient/client_notify.c. Also,
4120 implemnted the printing of the SERVER_SIGNOFF info to the
4121 application. Affected file silc/client_ops.c.
4123 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4124 if the deleting was successful. Affected file silcd/idlist.[ch].
4126 * Added support for public key authentication in the connection
4127 authentication protocol in the client library. Affected file
4128 lib/silcclient/protocol.c.
4130 * Changed the server's silc_idlist_get_clients_by_* interface
4131 to support already allocated array so that new entries may be
4132 added to pre-allocated array. Affected file silcd/idlist.[ch].
4133 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4134 and command replies.
4136 * All command reply functions in the server now calls the
4137 pending command callback even if error occured. This way the
4138 error will be delivered to the client as well. Affected files
4139 silcd/command.c and silcd/command_reply.c.
4141 * Fixed INFO command to return local server's info if no server
4142 was provided. Affected file lib/silcclient/command.c.
4144 * Removed RESTART command for good. Updated the code and the
4147 * Rewrote parts of the task system. It is a bit simpler now.
4148 Removed unsued task priorities. The affected files are
4149 lib/silcutil/silctask.[ch].
4151 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Moved the USERS printing from the library to the application.
4154 Affected files lib/silcclient/command.c and silc/client_ops.c.
4156 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Added channel key re-key support. The re-key is perfomed
4161 only by the router and is done once in an hour. Added `rekey'
4162 field to the SilcChannelEntry in the server. Affected files
4163 silcd/server.c and silcd/idlist.h.
4165 * Added silc_task_unregister_by_context into the file
4166 lib/silcutil/silctask.[ch].
4168 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Added SILC_UMODE_GONE mode to indicate when the client is not
4171 present in the SILC network. Added also support to the local
4172 command AWAY that will set this mode. Added support of showing
4173 "xxx is gone" in WHOIS command. The USERS command shows the
4174 gone status as well.
4176 * Fixed setting server and router operator privileges in the
4177 server's UMODE command. Affected file silcd/command.c.
4179 * Merged the SKE KE1 and KE2 payloads into one payload. The
4180 new KE payload is equivalent to the old KE2 payload.
4182 Cleaned up the SKE Start Payload parsing. It now uses the
4183 simple buffer unformatting to do the parsing. A lot faster
4186 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4187 to the SKE that is used to indicate whether both of the SKE
4188 parties should perform authentication. By default only the
4189 responder performs authentication. By setting this flag also
4190 the initiator must do authentication. By default it is unset
4191 since in normal SKE case, client to server connection, only
4192 the responder should do authentication. When doing SKE between
4193 two clients both should perform authentication. Updated the
4194 code and the protocol specs.
4196 * A little fix to IDENTIFY command in the server. Search the
4197 client first by hash not nickname. Affected file is
4200 * Fixed the silc_client_close_connection to support closing
4201 the client to client connections wihtout deleting too much
4202 data. Affected file lib/silcclient/client.c.
4204 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4205 are received if protocol used to be active but is not anymore
4206 the application would crash due to NULL pointer dereference.
4207 Affected files silcd/server.c and lib/silcclient/client.c.
4209 * Added `hash' field to the SilcClientConnection to include
4210 the hash function negotiated in the SKE protocol.
4212 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4213 to set the channel founder authentication data. A client can
4214 claim the founder rights later by providing the authentication
4215 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4216 This way the channel founder can regain the channel founder
4217 privileges even it is left the channel. This works only on
4218 local server and the client must be connected to the same
4219 server to be able to regain the founder rights. Updated the
4220 protocol specs accordingly.
4222 Added support to the CMODE command in the client to set the
4223 founder auth data. Read the README to see how to set it.
4225 Added support to the CUMODE command to claim the founder
4226 rights. Read the README to see how to do it.
4228 Added support for the founder authentication to the Channel
4229 Entry in the server. Affected file silcd/idlist.h.
4231 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4232 server's CMODE command. Affected file silcd/command.c.
4234 * Added the following new functions into lib/silccore/silcauth.[ch]:
4235 silc_auth_get_method and silc_auth_get_data.
4237 * The server now saves the remote hosts public key to the
4238 SilcIDListData pointer. Affected file silcd/protocol.c.
4240 * The normal server now does not remove the channel entry from
4241 the cache if the founder authentication data is set. It used
4242 to remove it if the founder was the last one on the channel on
4243 the server and left the channel. The auth data is saved and
4244 if the channel is re-joined later the old entry is used with
4245 the old auth data. Affected files silcd/command_reply.c and
4248 * Removed the `pkcs' field from the SilcIDListData structure
4249 in the server; it is not used. Affected file silcd/idlist.h.
4251 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Fixed packet processing on slow links. Partial packets were
4254 never re-processed because the incoming data buffer was cleared
4255 by the application. Application must not directly clear the
4256 sock->inbuf, the packet processing routines handle it. Fixed
4257 this in client library and in server.
4259 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Fixed the WHOIS and IDENTIFY send reply function to really
4262 check whether to send list or just one entry. Affected file
4265 * Cleaned up the LEAVE command's channel key distribution. The
4266 affected file silcd/command.c.
4268 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4269 can enforce the channel mode as well. In that case the ID
4270 includes the ID of the server. The code now enforces the
4271 mode change if the router have different mode than the server.
4273 * The notify client operation with CMODE_CHANGE notify can now
4274 return NULL client_entry pointer if the CMODE was not changed
4275 by client. Application must check for this.
4277 * Added <Server ID> argument to INFO command to support server
4278 info fetching by Server ID.
4280 * Added silc_server_announce_get_channel_users to get assembled
4281 packets of channel users of the specified channel. Affected
4282 file silcd/server.[ch].
4284 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4285 was freed underneath the ID Cache.
4287 * Re-announce clients when the server received CHANNEL_CHANGE
4288 notify from the router. Affected file silcd/packet_send.c.
4290 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4293 crashed since it did not handle the fact that there is no cipher
4294 called "3" and didn't check the error condition. Now fixed.
4296 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4297 flag. It can be used to send message requests.
4299 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Implemented the RESTART command in the client.
4303 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4304 notice type messages. Added notice printing to the user
4307 * The channel keys are not re-generated if the channel's mode
4308 is PRIVKEY, ie private key on the channel exists. Affected
4309 files silcd/server.c and silcd/command.c.
4311 * Fixed a little bug in channel message delivery when channel
4312 private keys are set in the server. Affected file is
4313 silcd/packet_send.c.
4315 * Changed the setting on channel->on_channel = TRUE from the
4316 silc_client_save_channel_key to the JOIN command reply. The
4317 key payload is not received if the private channel key is set.
4318 Affected file lib/silcclient/command_reply.c and the
4319 lib/silcclient/client_channel.c.
4321 * When the CMODE_CHANGE notify is sent and the channel private
4322 key mode is removed the channel key must be re-generated in
4323 other cells as well. Added this support for the router in the
4324 silcd/packet_receive.c.
4326 * Added new local command NOTICE to send notice message on
4327 channel. Affected file silc/local_command.[ch].
4329 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Added new local command ME to the client. It is used to send
4332 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4333 some action. Affected file silc/local_command.[ch].
4335 * Changed channel_message and private_message client operations
4336 to deliver the message flags to the application. Added also
4337 the `flags' arguments to the silc_client_send_channel_message
4338 and silc_client_send_private_message functions. Affected file
4341 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Redefined the Private Message Payload to support private message
4344 keys and to support the new private message flags. Updated
4345 the protocol specs. Flags makes it possible to have for example
4346 CTCP style messages.
4348 * Added new type SilcPrivateMessagePayload and defined an API
4349 for it in the lib/silcclient/silcprivate.[ch].
4351 * Tested private message private keys successfully. Tested the
4352 private message key set, unset and list commands with the new
4355 * Redefined the Channel Message Payload to include the channel
4356 message flags (equal with private message flags) to support
4357 for example CTCP style messages.
4359 * Defined some of the message (for channel and private message)
4360 flags. Updated the protocol specs and added the flags to the
4361 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4363 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Added SilcKeyAgreementStatus type to the key agreement routines
4366 to indicate the current status and error if one occured.
4367 The status types are defined in the lib/silcclient/silcapi.h.
4369 * Added new local command KEY that is used to set and unset private
4370 keys for channels, set and unset private keys for private messages
4371 with remote clients and to send key agreement requests and
4372 negotiate the key agreement protocol with remote client. The
4373 key agreement is supported only to negotiate private message keys,
4374 it currently cannot be used to negotiate private keys for channels,
4375 as it is not convenient for that purpose.
4377 * Fixed a minor pending callback setting bug in the function
4378 silc_client_get_client_by_id_resolve, now the function works.
4379 Affected file lib/silcclient/idlist.c.
4381 * Added function silc_net_get_local_port to get local bound
4382 port by socket. Added to lib/silcutil/silcnet.[ch].
4384 * Added `sockets' and `sockets_count' fields to the SilcClient
4385 object. They hold the sockets of the listenning sockets in
4386 the client. Listenning sockets may be for example the key
4387 agreement server. Affected file lib/silcclient/client.[ch].
4388 Added functions the silc_client_add_socket and the
4389 silc_client_del_socket. They are exported to the application
4392 * Added ~./silc/clientkeys to support other client's public keys.
4394 * Renamed verify_server_key client operation to verify_public_key
4395 and added one argument to indicate the type of the connection
4396 (server, client etc.).
4398 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Added silc_server_connection_auth_request to handle the
4401 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4402 silcd/packet_receive.[ch].
4404 * Added silc_server_send_connection_auth_request into the
4405 silcd/packet_send.c to send the connection auth request packet.
4407 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4410 * Fixed the public key authentication in responder side in the
4411 server. The `auth_data' pointer includes the SilcPublicKey
4412 not the path to the public key. Affected file silcd/protocol.c.
4414 * Implemented the public key authentication in the initiator side
4415 in the server. Affected file silcd/protocol.c.
4417 * Removed the [RedirectClient] config section from the server
4418 configuration. Is not needed and I don't want to implement it.
4420 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Cleaned up the CMODE command in the server. It now works
4423 correctly and supports all the modes defined in the protocol.
4424 Affected file is silcd/command.c.
4426 * Added `hmac_name' field to the SilcChannelEntry in the server
4427 to hold the default HMAC of the channel. It can be set when
4428 creating the channel (with JOIN command). Affected files
4431 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4432 type to indicate the change of the current cipher and hmac
4433 on the channel. Client can safely ignore the <cipher> argument
4434 (if it chooses to do so) since the CHANNEL_KEY packet will
4435 force the channel key change anyway. The <hmac> argument is
4436 important since the client is responsible of setting the new
4437 HMAC and the hmac key into use.
4439 * Fixed the CMODE command in the client library as well.
4441 * Tested CMODE command in router environment successfully.
4443 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Show the version of the remote client (or server) when connecting
4446 to the server. It is logged to the log file. Affected file
4447 is silcd/protocol.c.
4449 * Fixed the KILLED notify handling in the client library. The
4450 client must be removed from all channels when receiving the
4453 Also, do not remove the client entry when giving the KILL
4454 command but when the KILLED notify is received.
4456 * Removed silc_idlist_find_client_by_nickname from the server.
4457 Not needed anymore. Affected files silcd/idlist.[ch].
4459 * Implemented the CHANNEL_CHANGE notify type handling to the
4460 server. Affected file silcd/server.c.
4464 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added silc_server_send_notify_invite to send the INVITE
4467 notify between routers.
4469 * Implemented the INVITE command correctly to the server.
4471 * Implemented the INVITE notify type handling in the server.
4473 * Implemented the INVITE command to the client library and on the
4476 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Added function silc_server_get_client_resolve to find the
4479 client entry by ID from all ID lists and then resolve it
4480 (using WHOIS) if it cannot be found. Affected file is
4483 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Implemented the BAN command to the client library.
4487 * The JOIN command in the server now checks the invite list
4490 * Changed the silc_command_reply_payload_encode_va and the
4491 silc_command_payload_encode_va to support that if argument is
4492 NULL it ignores and checks the next argument. Affected file
4493 lib/silccore/silccommand.c.
4495 * Added silc_server_send_notify_ban to send the BAN notify
4496 type between routers.
4498 * Chaned the silc_notify_payload_encode to support that if
4499 argument is NULL it ignores and checks the next argument.
4500 Affected file lib/silccore/silcnotify.c.
4502 * Tested ban lists in router environment successfully.
4504 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Implemented BAN command to the server, in silcd/command.[ch].
4508 * Removed the BAN and INVITE_LIST modes from the CMODE command
4511 * Added function silc_string_match to regex match two strings.
4512 Affected files lib/silcutil/silcutil.[ch].
4514 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Redefined parts of the SilcChannelEntry in the server to support
4517 the new ban and invite lists.
4519 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Redefined the INVITE command. The same command can be used to
4522 invite individuals to the channel but also to manage the invite
4523 list of the channel (to add to and remove from the invite list).
4524 Updated the protocol specs.
4526 * Added new command SILC_COMMAND_BAN that can be used to manage
4527 the ban list of the channel. Updated the protocol specs.
4529 * Removed the channel modes: the SILC_CMODE_BAN and the
4530 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4531 in the CMODE command. The equivalent features are now available
4532 using INVITE and BAN commands. Updated the protocol specs.
4534 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4535 in the network about change in the current ban list. The notify
4536 type is not used by the client.
4538 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4539 support the invite lists.
4541 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Added new function silc_string_regexify that converts string
4544 including wildcard characters into regex string that can
4545 be used by the GNU regex library. Added into the file
4546 lib/silcutil/silcutil.[ch].
4548 Added silc_string_regex_combine to combine to regex strings
4549 into one so that they can be used as one regex string by
4550 the GNU regex library. Added into the file
4551 lib/silcutil/silcutil.[ch].
4553 Added silc_string_regex_match to match two strings. It returns
4554 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4556 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Imported GNU regex to the soruce tree into lib/contrib.
4559 Fixed some compiler warning from the regex.c.
4561 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Fixed MOTD command in the server to work in router environment.
4565 * Fixed the MOTD command in the client library to support
4566 the server argument in the command.
4568 * Added `nickname_len' argument to the silc_idlist_add_client
4569 in the server, as the `nickname' argument may be binary data
4572 * Added silc_idlist_get_channels to return all channels from
4575 * Implemented LIST command to the server. Affected file is
4578 * Implemented the LIST command to the client library and on the
4581 * Added [<user count>] argument to the LIST command reply.
4582 With private channels the user count is not shown.
4584 * Updated TODO and README.
4586 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * The client entry's data.registered must be TRUE even with
4589 global client entry on global client list. The data.registered
4590 is used to check whether the client is anymore in the network,
4591 for example with WHOWAS command so it must be valid.
4593 * Fixed the WHOWAS command in the server. It now actually works
4594 in router environment. Added function into silcd/command_reply.c
4595 silc_server_command_reply_whowas_save.
4597 * Added silc_idlist_purge function to the silcd/idlist.c
4598 to periodically purge the ID Cache.
4600 * Fixed INFO command in the server. It works now in router
4601 environment. Added <server name> argument to the INFO command
4602 reply. Updated the protocol specs.
4604 * Fixed minor bug in silc_idcache_purge to not purge if the
4605 expire value is zero.
4607 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4608 they were buggy because of the WHOWAS information.
4610 * Fixed local command MSG to handle the async resolving of
4611 the remote client properly. It used to fail the first MSG.
4612 Affected file silc/local_command.c.
4614 * Added `data_len' field to SilcIDCache context.
4616 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Update TODO. Todo in commands in the server.
4620 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4623 used by routers as broadcast packet to inform other routers
4624 about the changed user mode.
4626 Implemented the notify handling in the server. Affected file is
4627 silcd/packet_receive.c. Added the function
4628 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4630 * Added new generic Channel Payload and deprecated the New Channel
4631 Payload. The New Channel Payload is now the generic Channel
4634 * Added new argument `mode' to the silc_server_send_new_channel
4635 as it is required in the Channel Payload now.
4637 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4638 and created a new and real SilChannelPayload to represent the
4639 new generic Channel Payload. Implemented the encode/decode
4640 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4642 * Added silc_server_get_client_channel_list to return the list
4643 of channels the client has joined for WHOIS command reply.
4644 Affected file silcd/server.[ch].
4646 * Implemented the channel list sending in the WHOIS command reply
4647 in server and in the client.
4649 Implemented the channel list displaying on the user interface
4650 as well. Affected file silc/client_ops.c.
4652 * Added silc_channel_payload_parse_list to parse list of Channel
4653 Payloads. It returns SilcDList list of SilcChannelPayloads.
4654 Client for example can use this function to parse the list of
4655 channels it receives in the WHOIS command reply. The caller
4656 must free the list by calling silc_channel_payload_list_free.
4657 Affected files lib/silccore/silcchannel.[ch].
4659 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Added one new argument <user mode> to the WHOIS command reply
4662 to return the mode of the user in SILC. Updated the protocol
4665 Implemented it to the server and client.
4667 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Fixed the mode printing on the user interface on joining.
4670 Affected file silc/client_ops.c.
4672 * Implemented the UMODE command and user modes in general to the
4673 client library and to the user interface.
4675 * Implemented the UMODE command to the server.
4677 * The server now sends UNKNOWN_COMMAND error status if client sends
4678 unknown command. Affected file silcd/command.c.
4680 * All server commands now handle the command identifier the right
4681 way when sending the command reply to the client. The client can
4682 use to identify the command replies with the identifier.
4684 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Added silc_server_get_client_route to resolve the route to
4687 the client indicated by the client ID. Affected file is
4690 * Added silc_server_relay_packet as general function to relay
4691 packet to arbitrary destination. This deprecates functions
4692 like _send_private_message_key, _relay_notify etc. Affected
4693 file is silcd/packet_send.[ch].
4695 Removed silc_server_send_key_agreement,
4696 silc_server_send_private_message_key and
4697 silc_server_packet_relay_notify functions from the file
4698 silcd/packet_send.[ch].
4702 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4703 server. Affected file silcd/packet_receive.[ch].
4705 * Implemented the KILL command to the client. Implemented the
4706 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4707 Affected files lib/silcclient/command[_reply].c and
4708 lib/silcclient/client_notify.c. Implemented the KILL notify
4709 printing in the user inteface.
4711 * Fixed a lot silc_parse_nick memory leaks from the client
4712 library in the file lib/silcclient/command.c.
4714 * Changed the silc_server_send_notify_on_channels's `sender'
4715 argument from SilcSocketConnection to SilcClientEntry to
4716 check the sender as entry and not as connection object and not
4717 to send to the client provided as argument. The affected file
4718 is silcd/packet_send.[ch].
4720 * The notify packets that are destined directly to the client used
4721 to not to be processed by the server. Now changed that and the
4722 server processes all notify packets. After relaying the packet
4723 to the client the notify packet is processed in the server.
4725 * The silc_server_free_client_data now checks whether there is
4726 pending outgoing traffic for the client and purges the data to
4727 the network before removing the client entry.
4729 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4732 an client is killed from the SILC Network. Updated the protocol
4735 Added new function silc_server_send_notify_killed to the
4736 silcd/packet_send.[ch].
4738 * Added function silc_server_packet_relay_notify to relay notify
4739 packets that are destined directly to a client. In this case
4740 the server does not process the notify packets but merely relays
4741 it to the client. Affected file silcd/packet_send.[ch].
4743 Added also silc_server_packet_process_relay_notify to check
4744 whereto relay the notify. Affected file is
4745 silcd/packet_receive.[ch].
4747 * Implemented the KILL command to the server.
4751 * Added the backup schema desgined last fall to the protocol
4752 specs for everyone to see. The specification is in the
4753 *-spec-xx.txt draft and the packet type definitions for the
4754 backup routers is in *-pp-xx.txt draft. Thusly, added also
4755 new packet type SILC_PACKET_CELL_ROUTERS.
4757 * A big security problem in the implementation discovered. The
4758 signoff of an client did not cause new channel key generation
4759 which it of course should've done. The channel keys must be
4760 always re-generated when client leaves (or signoffs) the channel.
4761 The silc_server_remove_from_channels funtion now handles
4762 the channel key re-generation.
4764 * Added `sender' argument to the silc_server_send_notify_on_channels
4765 to not to send the client provided as argument. Affected file
4766 silcd/packet_send.[ch].
4768 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Implemented OPER and SILCOPER commands into the server and
4773 * Added silc_auth_verify and silc_auth_verify_data to verify
4774 the authentication directly from the authentication payload.
4775 It supports verifying both passphrase and public key based
4776 authentication. Affected file lib/silccore/silcauth.[ch].
4778 * Added `hash' field to the SilcIDListData structure. It is the
4779 hash negotiated in the SKE protocol. Affected file is
4782 * Slight redesigning of the SilcAuthPayload handling routines.
4783 Do not send SilcPKCS but SilcPublicKey as argument.
4785 * Implemented the public key authentication support to the
4786 serverconfig. The public key is loaded from the provided path
4787 and saved as authentication data to void * pointer. Thus,
4788 changed the unsigned char *auth_data to void *auth_data;
4790 * Fixed SHUTDOWN command to send the reply before the server
4791 is shutdown. :) Affected file silcd/command.c.
4793 * Fixed fatal bug in CONNECT command. The hostname was invalid
4794 memory and server crashed. Affected file silcd/command.c.
4796 * Fixed fatal bug in CLOSE command. The server_entry became
4797 invalid but was referenced later in the command. Affected file
4800 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Fixed fatal bug in failure packet handling. Server ignored
4803 the failure and thus crashed when it came.
4807 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4810 that the command may be executed only once in (about) 2 seconds.
4811 The old SILC_CF_LAG flag is same but allows command bursts up
4812 to five before limiting.
4814 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4815 server code. Various commands now includes the CF_LAG_STRICT
4816 flag to disallow any kind of miss-use of the command.
4818 * Fixed the silc_buffer_unformat to not to allocate any data
4819 if the length of the data is zero. It used to allocate the
4820 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4822 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Changed the format of AdminConnection configuration section
4825 in the server. Added username of the admin to the format.
4826 Affected files silcd/serverconfig.[ch].
4828 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4829 to return admin configuration data by host, username and/or
4832 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Implemented WHOWAS command to the server. Added the functions:
4836 silc_server_command_whowas_parse,
4837 silc_server_command_whowas_send_reply,
4838 silc_server_command_whowas_from_client and
4839 silc_server_command_whowas_from_server
4841 * Added <Client ID> argument to the WHOWAS command reply. Updated
4842 the protocol specs accordingly.
4844 * Implemented WHOWAS command and command_reply to the client
4847 Implemented the WHOWAS printing on the user interface.
4849 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * Added new argument to the WHOWAS command reply, the real name.
4852 It is an optional argument. Updated the protocol specs.
4854 * Added SilcIDCacheDestructor callback that is registered when
4855 the SilcIDCache is allocated. The callback is called when
4856 an cache entry in the ID Cache expires, or is purged from the
4857 cache. Added into lib/silccore/idcache.[ch].
4859 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4860 to destruct the client entries when the cache entry expires.
4861 Other ID Cache's in server and in the client library ignores
4864 * If the ID Cache entry's `expire' field is zero then the entry
4865 never expires. Added boolean `expire' argument to the
4866 silc_idcache_add function in the lib/silccore/idcache.[ch].
4867 If it is TRUE the default expiry value is used.
4869 * Added silc_server_free_client_data_timeout that is registered
4870 when client disconnects. By default for 5 minutes we preserve
4871 the client entry for history - for WHOWAS command.
4873 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Added support to the server to enforce that commands are not
4876 executed more than once in 2 seconds. If server receives
4877 commands from client more frequently, timeout is registered
4878 to process the commands. Affected file silcd/command.c.
4879 Added new function silc_server_command_process_timeout.
4881 * Changed NICK_NOTIFY handling in client library to check that
4882 if the client's nickname was changed, so there is no need to
4883 resolve anything from the server.
4885 * Removed error printing from the WHOIS and IDENTIFY commands.
4886 If error occurs then it is ignored silently in the client library.
4887 The application, however, may map the received error to
4888 human readable error string. The application currently maps
4889 the NO_SUCH_NICKNAME error to string.
4891 * Made the command status message public to the application. Moved
4892 them from lib/silcclient/command_reply.c to
4893 lib/silcclient/command_reply.h. The application can map the
4894 received command status to the string with the
4895 silc_client_command_status_message function.
4897 * Added check to the server to check that client's ID is same
4898 as the Source ID in the packet the client sent. They must
4901 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Added dist-bzip hook to the Makefile.am to make bzip2
4904 compressed distributions.
4906 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Server now enforces the maximum length for the nickname and
4909 the channel as protocol specification dictates. 128 bytes for
4910 nickname and 256 bytes for channel name.
4912 * Moved the WHOIS printing to the application. The client libary
4913 does not print out the WHOIS information anymore, the application
4914 must do it. Renamed silc_client_command_reply_whois_print to
4915 the silc_client_command_reply_whois_save.
4917 The client's idle time is also sent to the application now, and
4918 the idle is shown on screen.
4920 * Added silc_client_command_reply_identify_save to save the
4921 received IDENTIFY entries.
4923 * Do not check for channel private keys in message sending and
4924 reception if the channel does not have the PRIVKEY mode set.
4925 Affected file lib/silclient/client_channel.c.
4927 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4930 just surfaced after chaning the JOIN procedure.
4932 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Added silc_client_get_clients_by_list to get client entries
4935 from Client ID list, that is returned for example by JOIN
4936 and USERS command replies. The application should use this
4937 function for example when JOIN command reply is received to
4938 resolve the clients already on the channel (library does not
4939 do that anymore as USERS command reply is not used in the JOIN
4940 procedure anymore). Affected files lib/silcclient/silcapi.h and
4941 lib/silcclient/idlist.c.
4943 * JOIN command reply and USERS command reply returns now SilcBuffer
4944 pointers instead of unsigned char pointers when returning
4945 the client list and mode list.
4947 * Added <Client ID> argument to the JOIN command reply, mainly
4948 for the server to identify for which client the command was
4949 originally sent. Updated protocol specs accordingly.
4951 * Added SilcDlist private_key pointer to the SilcChannelEntry
4952 in the client to support the channel private keys. Affected
4953 file is lib/silcclient/idlist.h.
4955 * Added SilcChannelPrivateKey argument to the function
4956 silc_client_send_channel_message so that application can choose
4957 to use specific private ke if it wants to. If it is not provided,
4958 the normal channel key is used, unless private keys are set.
4959 In this case the first (key that was added first) is used
4960 as the encryption key.
4962 * Implemented the support for channel private key handling.
4963 Implemented the following functions:
4965 silc_client_add_channel_private_key,
4966 silc_client_del_channel_private_keys,
4967 silc_client_del_channel_private_key,
4968 silc_client_list_channel_private_keys and
4969 silc_client_free_channel_private_keys
4971 Affected file lib/silcclient/client_channel.c.
4973 * Added the support for the private keys in the channel message
4974 sending and encryption and in the message reception and
4975 decryption. Affected funtions are
4976 silc_client_send_channel_message and silc_client_channel_message.
4978 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Added SKE's key verify callback to the client library's
4981 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4983 * Removed the statement that server (or router) must send USERS
4984 command reply when joining to the channel so that the client
4985 knows who are on the channel. Instead, the client list and
4986 client's mode list is now sent in the JOIN command reply to the
4987 client who joined channel. This is better solution.
4989 * Added function silc_server_get_users_on_channel and function
4990 silc_server_save_users_on_channel to the silcd/server.[ch].
4992 * Removed function silc_server_command_send_users from the
4995 * Do not show topic on the client library anymore. The topic is
4996 sent in the command reply notify to the application and the
4997 application must show the topic now.
4999 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added client searching by nickname hash into the IDENTIFY and
5002 WHOIS commands in the server as they were clearly missing from
5003 them. Affected file is silcd/command.c.
5005 * Fixed a bug in private message receiving in the client library.
5006 The remote ID was freed and it wasn't supposed, now it is
5009 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Minor fix to the channel payload; allocate the data area, as it
5012 needs to be of specific length.
5014 * If the key agreement port is zero then the operating
5015 system will define the bound port. Affected files are
5016 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5018 * Added new function silc_channel_payload_decrypt into the file
5019 lib/silccore/silcchannel.[ch].
5021 * Moved the channel message etc, check from silc_packet_decrypt
5022 to applications. The library calls now a generic
5023 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5024 when the packet is either normal or special. This was done to
5025 allow more wide range of checking that was not allowed when
5026 the code was in library. Now applications can do virtually any
5027 checks to the packet and return to the library the decision how
5028 the packet should be processed. Affected files are
5029 lib/silccore/silcpacket.[ch].
5031 Added silc_server_packet_decrypt_check to the server and
5032 silc_client_packet_decrypt_check to the client library.
5034 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5035 to send with specified source and destination information.
5037 * Channel message delivery between routers was broken after the
5038 channel key distribution was fixed earlier. The channel key
5039 was used be to distributed to other routers as well which is not
5040 allowed by the protocol. Now this is fixed and channel keys
5041 really are cell specific and the channel message delivery between
5042 routers comply with the protocol specification.
5044 * Fixed various commands in server to check also the global list
5045 for the channel entry and not just the local list. The affected
5046 file silcd/command.c.
5048 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Added assert()s to buffer formatting and unformatting routines
5051 to assert (if --enable-debug) when error occurs. Affected
5052 file: lib/silcutil/silcbuffmt.c.
5054 * Changed to auto-reconnect to check whether the remote host is
5055 router and register the re-connect timeout if it is. It used
5056 to check that whether we are normal server, but router must do
5057 auto-reconnect with another router as well. Affected file
5060 * Removed the [<key len>] option from CMODE command as the cipher
5061 name decides the key length, nowadays. See the defined ciphers
5062 from the protocol specification.
5064 * Added [<hmac>] option to the CMODE command to define the HMAC
5065 for the channel. Added SILC_CMODE_HMAC channel mode.
5067 * Added [<hmac>] option for the JOIN command so that user can
5068 select which HMAC is used to compute the MACs of the channel
5071 * Added Hmac field to the Channel Message Payload. The integrity
5072 of plaintext channel messages are now protected by computing
5073 MAC of the message and attaching the MAC to the payload. The
5074 MAC is encrypted. Now, it is clear that this causes some
5075 overhead to the size of the packet but rationale for this is that
5076 now the receiver can verify whether the channel message decrypted
5077 correctly and also when private keys are set for the channel the
5078 receiver can decrypt the packet with several keys and check from
5079 the MAC which key decrypted the message correctly.
5081 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5082 lib/silccrypt/silccipher.[ch].
5084 * Added silc_hash_len to return the digest length into the
5085 lib/silcrypt/silchash.[ch].
5087 * Rewrote parts of Silc Channel Payload interface in the
5088 lib/silccore/silcchannel.[ch]. The encode function now also
5089 encrypts the packet and parse function decrypts it.
5091 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Fixed a minor formatting bug in the SKE's key material processing.
5094 It actually might have processed the keys wrong way resulting
5097 * Redefined the mandatory HMAC algorithms and added new algorithms.
5098 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5099 and hmac-md5 truncated to 96 bits. The mandatory is now
5100 hmac-sha1-96. Rest are optional (including the one that used
5101 to be mandatory). Rationale for this is that the truncated HMAC
5102 length is sufficient from security point of view and can actually
5103 make the attack against the HMAC harder. Also, the truncated
5104 HMAC causes less overhead to the packets. See the RFC2104 for
5107 * Added new [hmac] configuration section. The SKE used to use
5108 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5109 is of course wrong. The official names that must be proposed in
5110 the SKE are the ones defined in the protocol specification
5111 (hmac-sha1-96 for example). The user can configure any hmac
5112 using any hash function configured in the [hash] section. At
5113 least, the mandatory must be configured.
5115 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5117 * Added HMAC list to the SKE proposal list. It has now both
5118 hash algorithm list and HMAC list. This makes the protocol
5119 incompatible with previous versions. The SKE now seems to work
5120 the way it is supposed to work, for the first time actually.
5122 * Defined plain Hash algorithms to the protocol specification.
5125 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Implemented support for key agreement packets into the server.
5128 Added functions silc_server_key_agreement and
5129 silc_server_send_key_agreement. Other than these functions,
5130 server has nothing to do with this packet.
5132 * Added support for private message key packets into the server.
5133 Added functions silc_server_private_message_key and
5134 silc_server_send_private_message_key.
5138 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5139 called in the protocol's final callback instead in the END
5140 protocol state. This makes a little more sense and in the same
5141 time in client we can use the same protocol routines for normal
5142 key exchange and to key agreement packet handling as well.
5144 * Added to both client's and server's KE protocol context the
5145 SilcSKEKeyMaterial pointer to save the key material. We will
5146 bring the key material to the protocol's final callback by doing
5147 this. The final callback must free the key material.
5149 * Added SKE's packet_send callback into client's KE protocol
5150 context so that the caller can choose what packet sending function
5151 is used. This way we can use different packet sending when
5152 doing normal SKE when doing key agreement packet handling (in
5153 the key agreement packet handling we do not want to encrypt
5156 * Implemented the responder side of the key agreement routines
5157 in the client. The client can now bind to specified port and
5158 accept incoming key negotiation. The key material is passed
5159 to the application after the protocol is over.
5161 * Implemented the processing of incoming Key Agreement packet
5162 in the client. Added function silc_client_key_agreement to
5165 * Implemented the intiator side of the key agreement routines
5166 in the client. The client can now initiate key agreement with
5167 another remote client. The key material is passed to the
5168 application after the protocol is over.
5170 * Created client_keyagr.c to include all the key agreement
5173 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5174 SILC_TASK_CALLBACK except that it is not static.
5176 * Created client_notify.c and moved the Notify packet handling
5177 from the client.[ch] into that file.
5179 * Created client_prvmsg.c and moved all private message and
5180 private message key routines from the client.[ch] into that file.
5182 * Create client_channel.c and moved all channel message and
5183 channel private key routines from the client.[ch] into that file.
5185 * Changed silc_client_get_client_by_id_resolve to resolve with
5186 WHOIS command instead of IDENTIFY command, in the file
5187 lib/silclient/idlist.c.
5189 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Implemented the SKE's responder side to the Client library.
5193 * When FAILURE is received to the protocol do not trust it
5194 blindly. Register a timeout to wait whether the remote closes
5195 the connection as it should do it, only after that process the
5196 actual failure. This was changed to both client and server.
5198 * Added client_internal.h to include some of the structures
5199 there instead of client.h in lib/silcclient/.
5201 * Added function silc_task_unregister_by_callback to unregister
5202 timeouts by the callback function.
5204 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Some "Incomplete WHOIS info" errors has been appearing on the
5207 log files. Took away the entry->userinfo check from WHOIS
5208 reply sending. The entry->userinfo is now " " if client did not
5209 provide one. I thought this was fixed earlier but something
5210 is wrong still. Let's see if the error still appears.
5212 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Fixed a minor bug in the login when the channel key is
5215 re-generated in the server. It used to generate the key in
5216 wrong order and thus caused problems in the channel traffic.
5218 * Fixed a minor bug in channel key distsribution after
5219 KICK command. The key was not sent to the router even though
5222 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Added silc_ske_process_key_material_data as generic routine
5225 to process any key material as the SILC protocol dictates. The
5226 function is used by the actual SKE library but can be used by
5227 applications as well. This relates to the private message keys
5228 and the channel private keys since they must be processed the
5229 same way the normal SILC session keys. The protocol dictates
5230 this. Affected files: lib/silcske/silcske.[ch].
5232 Added also silc_ske_free_key_material to free the
5233 SilcSKEKeyMaterial structure.
5235 * Defined silc_cipher_set_key function to set the key for
5236 cipher without using the object's method function. The affected
5237 files: lib/silccrypt/silccipher.[ch].
5239 * Implemented silc silc_client_add_private_message_key,
5240 silc_client_add_private_message_key_ske,
5241 silc_client_del_private_message_key,
5242 silc_client_list_private_message_keys and
5243 silc_client_free_private_message_keys functions in the
5246 Added functions silc_client_send_private_message_key to send
5247 the Private Message Key payload and silc_client_private_message_key
5248 to handle incoming Private Message Key payload.
5250 * Added Cipher field to the Private Message Key payload to set
5251 the cipher to be used. If ignored, the default cipher defined
5252 in the SILC protocol (aes-256-cbc) is used.
5254 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Removed lib/silcclient/ops.h file.
5258 Redefined parts of the SILC Client Library API. Created new
5259 file silcapi.h that deprecates the ops.h file and defines the
5260 published Client Library API. Defined also private message key
5261 API and channel private key API into the file.
5263 This is the file that the application must include from the
5264 SILC Client Library. Other files need not be included by
5265 the application anymore.
5267 * Added new key_agreement client operation callback and also
5268 defined the Key Agreement library API for the application.
5270 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5272 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5273 is used by clients to request key negotiation between another
5274 client in the SILC network. If the negotiation is started it
5275 is performed using the SKE protocol. The result of the
5276 negotiation, the secret key material, can be used for example
5277 as private message key.
5279 Implemented the Key Agreement payload into the files
5280 lib/silccore/silauth.[ch].
5282 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Redefined ciphers for the SILC protocol. Added some new ciphers
5285 and defined the key lengths for the algorithms. Changed the
5286 code accordingly. The default key length is now 256 bits.
5288 * Fixed SKE key distribution function silc_ske_process_key_material
5289 when the key length is more than 128 bits. The default key
5290 length in SILC is now 256 bits.
5292 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5293 to indicate unsupported algorithm.
5295 * Renamed rijndael.c to aes.c and all functions as well.
5297 * Fixed a long standing channel key setting bug in client library.
5298 Weird that it has never surfaced before.
5300 * Fixed bug in channel deletion. If the entire channel is removed
5301 then it must also delete the references of the channel entry
5302 from the client's channel list as the client's channel entry and
5303 the channel's client entry share same memory.
5305 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Implemented CONNECT and SHUTDOWN commands in the client.
5309 * Implemented CLOSE command to the client.
5311 * Added the function silc_idlist_find_server_by_name into the
5312 files silcd/idlist.[ch].
5314 Added the function silc_idlist_find_server_by_conn into the
5315 files silcd/idlist.[ch].
5317 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * DIE command was renamed to SHUTDOWN. Updated the both code
5322 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5323 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5325 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5328 * Added function silc_server_create_connection function to create
5329 connection to remote router. My server implementation actually
5330 does not allow router to connect to normal server (it expects
5331 that normal server always initiates the connection to the router)
5332 so the CONNECT command is only good for connecting to another
5335 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5338 or some other client was kicked from the channel.
5340 Implemented the handling of the notify type to both client
5343 Implemented silc_server_send_notify_kicked to send the KICKED
5344 notify. It is used to send it to the server's primary router.
5346 * Implemented the KICK command into server and client.
5348 * Added `query' argument to the silc_idlist_get_client function
5349 to indicate whether to query the client from server or not if
5352 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5353 to indicate that the client is not channel founder.
5357 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Removed the rng context from SilcPacketContext structure and
5360 changed that the packet routine uses the Global RNG API.
5362 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Added support for quit message that client can "leave" on the
5365 channel when it quits the SILC. It is ditributed inside the
5366 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5368 Added silc_server_free_client_data that will take the
5369 signoff message as argument.
5371 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5373 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Updated parts of the protocol specification to keep it up
5378 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5381 payloads in one packet.
5383 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5384 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5385 use now the new List flag.
5387 * Also deprecated the following packet types: REPLACE_ID,
5388 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5390 * Added list support for Notify packet in server.
5392 * Added silc_server_send_notify_channel_change to send the
5393 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5394 the silc_server_send_replace_id.
5396 * Added silc_server_send_notify_nick_change to send the
5397 NICK_CHANGE notify type. Deprecates the function
5398 silc_server_send_replace_id.
5400 * Added silc_server_send_notify_join to send the JOIN notify type.
5401 Deprecates the function silc_server_send_new_channel_user.
5403 * Added silc_server_send_notify_leave to send LEAVE notify type.
5404 Deprecates the function silc_server_send_remove_channel_user.
5406 * Added silc_server_send_notify_cmode and
5407 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5408 types. Deprecates the silc_server_send_set_mode function.
5410 * Added SERVER_SIGNOFF notify type to indicate that server has
5411 quit. This means that all clients on the channel from that
5412 server will drop. This can be also used when netsplit happens.
5414 Deprecated REMOVE_ID packet type since it is not needed anymore
5417 Added silc_server_send_notify_server_signoff to send the
5418 SERVER_SIGNOFF notify type. Deprecates the function
5419 silc_server_send_remove_id.
5421 Added also silc_server_send_notify_signoff to send the
5422 SIGNOFF notify type.
5424 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5425 SILC protocol from this day on. Changed the protocol
5426 specification as well.
5428 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5429 notify type. It is used between routers to notify about
5430 topic changes on a channel.
5432 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5435 * Partly updated the protocol specification to comply with the
5436 changes now made. It is still though a bit outdated.
5438 * The JOIN notify type now takes one extra argument <Channel ID>.
5439 The packet used to be destined to the channel but now the
5440 JOIN type may be sent as list thus it is impossible to
5441 destine it to any specific channel. By adding this argument
5442 it is again possible.
5444 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Added CREDITS file. The CHANGES and CREDITS file will appear
5447 in the distribution as well.
5449 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5452 types in the server's silcd/packet_receive.c.
5454 * Implemented CMODE and CUMODE to work in router environment.
5456 * Fixed minor encoding and decoding buglet from the
5457 lib/silccore/silcmode.c.
5459 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5462 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5464 * Changed all SilcConfigServer* and silc_config_server* to
5465 SilcServerConfig* and silc_server_config*, respectively.
5468 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Associated the ID (client or server ID) to the Authentication
5471 Payload to avoid any possibility of forging. Updated the
5472 protocol specification and the code accordingly.
5474 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * The RSA key length is now save to the RsaKey context in the
5477 key generation process in lib/silccrypt/rsa.c. The key length
5478 is now used to figure out the maximum size of the block allowed
5479 to be encrypted/signed.
5481 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5482 is equivalent to the silc_mp_mp2bin but does not allocate any
5485 * Changed silc_mp_mp2bin API to take length argument. If it is
5486 non-zero then the buffer is allocated that large. If zero, then
5487 the size is approximated using silc_mp_sizeinbase, which however
5490 * Created Global RNG API which is global RNG that application can
5491 initialize. After initializing, any routine anywhere in the
5492 code (including library) can use RNG without allocating a new
5493 RNG object. This was done to allow this sort of use of the
5494 RNG in code that has no chance to allocate RNG object. All
5495 applications currently allocate this and many routines in the
5496 library use this. Affected file lib/silccrypt/silcrng.[ch].
5498 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5499 it to use the Global RNG API.
5501 * Defined Authentication Payload into protocol specification that
5502 is used during SILC session to authenticate entities. It is
5503 used for example by client to authenticate itself to the server
5504 to obtain server operator privileges.
5506 Implemented this payload into the lib/silccore/silcauth.[ch].
5507 Implemented also routines for public key based authentication
5508 as the new protocol specification dictates.
5510 Moved definitions of different authentication methods from
5511 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5513 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5514 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5515 silc_pkcs_verify_with_hash functions into the file
5516 lib/silccrypt/silcpkcs.[ch].
5518 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * The client entry's userinfo pointer must be always valid.
5521 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5522 will fail since it requires the userinfo. Now, the userinfo
5523 is allocated as "" if actual userinfo does not exist. Actually,
5524 it must exist and it is totally Ok to drop client connections
5525 that does not announce the userinfo. However, we will make
5526 this workaround for now.
5528 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5529 to return the remote port by socket.
5531 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5534 SILC_SERVER_PENDING_EXEC and added an new macro
5535 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5536 data or when error occurs while processing the pending command.
5538 Added new argument `destructor' into silc_server_command_pending
5539 and to the SilcServerCommandPending object. This destructor is
5540 now called after calling the pending callback or if error occurs
5541 immediately. If error occurs the actual pending callback won't
5542 be called at all - only the destructor. The destructor may be
5543 NULL if destructor is not needed.
5545 All this applies for client library code as well. Similar
5546 changes were made there as well for the pending commands.
5548 In the client, the application must now allocate the
5549 SilcClientCommandContext with the silc_client_command_alloc
5552 * Added reference counter to the SilcServerCommandContext. Added
5553 function silc_server_command_alloc and silc_server_command_dup
5556 Same type of functions added to the client library for the same
5559 * Removed the cmd_ident from IDListData away since it is now
5560 global for all connections. It is the command identifier used
5561 in command sending and with pending commands. The affected file
5564 * Added reference counter to the SilcSocketConnection objecet to
5565 indicate the usage count of the object. The object won't be
5566 freed untill the reference counter hits zero. Currently only
5567 server uses this, and client ignores it. The client must be
5568 set to use this too later. The affected files are
5569 lib/silccore/silcsockconn.[ch]. Added also the function
5570 silc_socket_dup to increase the reference counter.
5572 This was mainly added because it is possible that the socket
5573 is removed underneath of pending command or other async
5574 operation. Now it won't be free'd and proper DISCONNECTING
5575 flags, etc. can be set to avoid sending data to connection that
5576 is not valid anymore.
5578 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5579 the connection. After that it sets SILC_SET_DISCONNECTED.
5580 It is, however, possible that the socket data is not still freed.
5581 The silc_server_packet_process now checks that data is not
5582 read or written to connection that is DISCONNECTED. The socket
5583 get's freed when the reference counter hits zero.
5585 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Changed the client operation API: channel_message operation's
5588 `sender' is now the client entry of the sender, not the nickname
5589 and the `channel' is the channel entry, not the channel name.
5591 In the private_message operation the `sender' is now also the
5592 client entry of the sender not the nickname.
5594 Affected file is lib/silcclient/ops.h and all applications
5595 using the client operations.
5597 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Moved the calling of ops->connect() from connect_to_server_final
5600 into receive_new_id functin since that is the point when the
5601 client is actually allowed to send traffic to network. The
5602 affected file is lib/silcclient/client.c.
5604 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5607 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5608 (if needs broadcasting) instead of broadcasting the packets one
5609 by one which would make a burst in the network traffic.
5611 * Added `broadcast' argument to the functions in silcd/server.[ch]
5612 silc_server_create_new_channel[_with_id] to indicate whether
5613 to send New Channel packet to primary router.
5615 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Added new function into the silcd/server.[ch] files:
5618 silc_server_create_new_channel_with_id to create new channel with
5619 already existing Channel ID.
5621 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5622 lib/silccore/silcpacket.h. This packet is used t send list of
5623 Set Mode payloads inside one packet. Server uses this to set
5624 the modes for the channels and clients on those channels, that it
5625 announced to the router when it connected to it. The protocol
5626 specification has been updated accordingly.
5628 * The silc_server_new_channel did not handle the packet coming
5629 from normal server as it normally does not send that. However,
5630 when it announces its channels it does send it. Implemented
5631 the support for that.
5633 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5634 into the file lib/silccore/id.h.
5636 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Fixed memory leaks in the functions silc_idlist_del_client,
5639 silc_idlist_del_channel and silc_idlist_del_server in the file
5640 silcd/idlist.c. All of those leaked like a sieve.
5642 * Fixed some small memory leaks in the client's function
5643 silc_client_notify_by_server.
5645 * Added functions into silcd/server.c: silc_server_announce_clients,
5646 silc_server_announce_channels and silc_server_announce_server.
5647 These functions are used by normal and router server to announce
5648 to its primary router about clients, channels and servers (when
5649 router) that we own. This is done after we've connected to the
5652 These functions effectively implements the following packet types:
5653 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5654 and SILC_PACKET_NEW_ID_LIST.
5656 * Added new functions into the silcd/packet_receive.[ch]:
5657 silc_server_new_id_list, silc_server_new_channel_list and
5658 silc_server_new_channel_user_list to handle the incoming
5659 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5661 * Added support of changing Channel ID in the function
5662 silc_server_replace_id. If the server that announces a channel
5663 to the router already exists in the router (with same name but
5664 with different Channel ID), router is responsible to send
5665 Replace ID packet to the server and force the server to change
5666 the Channel ID to the one router has.
5668 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5669 client that the Channel ID has been changed by the router. The
5670 normal server sends this to the client. Client must start using
5671 the new Channel ID as the channel's ID.
5673 Implemented handling of this new type into lib/silcclient/client.c
5674 into the function silc_client_notify_by_server.
5676 * Added new function silc_idlist_replace_channel_id into the files
5677 silcd/idlist.[ch] to replace the Channel ID.
5679 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Call silc_server_command_identify_check always when processing
5682 the IDENTIFY command in silcd/command.c
5684 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5687 send keepalive packets. The packet can be sent by clients,
5688 servers and routers.
5690 Added function silc_socket_set_heartbeat into the file
5691 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5692 If not set, the heartbeat is not performed. The actual
5693 heartbeat is implemented in the low level socket connection
5694 library. However, application is responsible of actually
5697 Added silc_server_send_heartbeat to send the actual heartbeat
5698 packet into silcd/packet_send.[ch]. Server now performs
5699 keepalive with all connections.
5701 * Added silc_task_get_first function into lib/silcutil/silctask.c
5702 to return the timeout task with shortest timeout. There was a bug
5703 in task unregistration that caused problems. TODO has been
5704 updated to include that task system must be rewritten.
5706 * The client library will now resolve the client information when
5707 receiving JOIN notify from server for client that we know but
5708 have incomplete information.
5710 * Rewrote parts of silc_server_remove_from_channels and
5711 silc_server_remove_from_one_channel as they did not remove the
5712 channel in some circumstances even though they should've.
5714 * Encryption problem encountered in server:
5716 The LEAVE command used to send the Channel Key packet to the
5717 router immediately after generating it. However, the code
5718 had earlier sent Remove Channel user packet but not immediately,
5719 ie. it was put to queue. The order of packets in the router
5720 was that Channel Key packet was first and Remove Channel User
5721 packet was second, even though they were encrypted in the
5722 reverse order. For this reason, MAC check failed. Now, this
5723 is fixed by not sending the Channel Key packet immediately but
5724 putting it to queue. However, this is more fundamental problem:
5725 packets that are in queue should actually not be encrypted
5726 because packets that are sent immediately gets encrypted
5727 actually with wrong IV (and thus MAC check fails). So, packets
5728 that are in queue should be encrypted when they are sent to
5729 the wire and not when they put to the queue.
5731 However, the problem is that the current system has not been
5732 designed to work that way. Instead, the packet is encrypted
5733 as soon as possible and left to the queue. The queue is then
5734 just purged into wire. There won't be any fixes for this
5735 any time soon. So, the current semantic for packet sending
5738 o If you send packet to remote host and do not force the send
5739 (the packet will be in queue) then all subsequent packets to the
5740 same remote host must also be put to the queue. Only after the
5741 queue has been purged is it safe again to force the packet
5744 o If you send all packets immediately then it safe to send
5745 any of subsequent packets through the queue, however, after
5746 the first packet is put to queue then any subsequent packets
5747 must also be put to the queue.
5749 Follow these rules and everything works fine.
5751 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Added new function silc_server_remove_clients_by_server to
5754 remove all client entries from ID list when the server connection
5755 is lost. In this case it is also important to invalidate all
5756 client entires as they hold the invalid server entry. This
5757 fixes fatal bug when server has lost connection and will reconnect
5760 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Made some sanity checks to silc_server_daemonise like to check
5763 whether the requested user and group actually exists.
5765 * Added sanity check to SKE's silc_ske_responder_finish to check
5766 that the public and private key actually is valid.
5768 * Invalidate the client's nickname when receiving Replace ID
5769 packet and the Client ID is being replaced. This means that the
5770 server will query the nickname if someone needs it (client)
5773 * Sort the ID Cache in client library when the ID Cache data
5774 has changed (needs sorting).
5776 * Do not allow for SILC client to create several connections to
5777 several servers. The client does not support windows right now
5778 and generating multiple connections causes weird behaviour.
5780 Irssi-silc client does support windows and can handle several
5781 connections without problems, see: www.irssi.org and SILC plugin.
5783 * Fixed some places where client was added to the IDList. The
5784 rule of thumb is following (in order to get everything right):
5785 If the client is directly connected local client then the
5786 `connection' argument must be set and `router' argument must be
5787 NULL to silc_idlist_add_client function. If the client is not
5788 directly connected client then the `router' argument must
5789 bet set and the `connection' argument must be NULL to the
5790 silc_idlist_add_client function.
5792 * The funtion silc_server_packet_send_local_channel actually did
5793 not check whether the client was locally connected or not. It
5794 does that now. Fixed a bug related to LEAVE command.
5796 * Fixed Remove Channel User payload parsing bug in server's
5797 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5799 * The server's silc_server_save_channel_key now checks also the
5800 global ID list for the channel as it might not be in the local
5801 list. Fixed a bug related to LEAVE command.
5803 * Is this the end of the [<unknown>] buglet that has been lurking
5804 around for a long time? A little for loop fix in server's
5805 silc_server_command_whois_parse that is used by both IDENTIFY
5806 and WHOIS command. At least, this was a clear bug and a cause
5807 of one type of [<unknown>] buglet.
5809 * WHOIS and IDENTIFY commands call the function
5810 silc_server_command_[whois/identify]_check function even if
5811 we are not router server.
5813 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Added --with-gmp configuration option. If set the GMP
5816 is always compiled in the SILC source tree. If not set then
5817 it is checked whether the system has the GMP3 installed. If
5818 it has then the GMP won't be compiled (the system's headers
5819 and library is used), if it doesn't have it then the GMP is
5820 compiled in the SILC source tree.
5822 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Changed RSA private exponent generation to what PKCS #1
5825 suggests. We try to find the smallest possible d by doing
5826 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5827 not security fix but optimization.
5829 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Added new config entry [Identity] to fork the server and run
5832 it as specific user and group. A patch from Bostik.
5834 * Imported Dotconf configuration library into lib/dotconf.
5835 This will be used to create the SILC configuration files later.
5836 It will appear in the distsribution after this commit.
5838 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * A big code auditing weekend happening. Auditing code for
5841 obvious mistakes, bugs and errors. Also, removing any code
5844 Removed files for being obsolete:
5846 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5847 inline in the file lib/silcutil/silcbuffer.h)
5849 o lib/silcutil/silcbufutil.c (the header has inline versions)
5851 Changed code to fix possible error conditions:
5853 o The buffer formatting routines now check that the destination
5854 buffer really has enough space to add the data. This applies for
5855 both buffer formatting and unformatting
5856 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5857 unformatting was changed to accomodate following rules:
5858 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5859 sent to the function while XXX_*STRING will not allocate or copy
5860 the data into the buffer. Instead it sets the pointer from the
5861 buffer into the pointer sent as argument (XXX_*STRING used to
5862 require that the pointer must be allocated already). This change
5863 makes this whole thing a bit more consistent and more optimized
5864 (note that the data returned in the unformatting with XXX_*STRING
5865 must not be freed now). The routines return now -1 on error.
5867 o Tried to find all code that use buffer_format and buffer_unformat
5868 and added return value checking to prevent formatting and
5869 especially unformatting errors and possible subsequent fatal
5872 o Changed ske->x and ske->KEY to mallocated pointers in
5873 lib/silcske/silcske.h. Fixed possible data and memory leak.
5875 o Added return value checking to all *_parse* functions. Fixed
5876 many memory leaks as well.
5878 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5879 so that buffer overflows would not happen. All code now also
5880 checks the return value as it can fail.
5882 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Added reconnection support to server if the normal server looses
5885 its connection to the router (for example if router is rebooted).
5886 The server performs normal reconnection strategy implemented
5887 to the server. Affected file silcd/server.c.
5889 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Added new packet type SILC_PACKET_SET_MODE that is used to
5892 distribute the information about changed modes (for clients,
5893 channels and clients channel modes) to all routers in the
5894 network. Updated the protocol specification accordingly.
5896 Added functions into silcd/packet_send.c and
5897 silcd/packet_receive.c: silc_server_send_set_mode,
5898 silc_server_set_mode.
5900 Added new files silcmode.[ch] into lib/silccore that implements
5901 the encoding and decoding of Set Mode Payload. Added new type
5902 SilcSetModePayload. Moved the definitions of different modes
5903 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5905 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Oops, a little mistake in server's connection authentication
5908 protocol. The protocol is not ended with FAILURE but with
5909 SUCCESS if the authentication is Ok. :) Affected file is
5912 * Implemented NICK_CHANGE notify handling in server in the file
5913 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5914 the local clients on the channel. After the changing nickname
5915 in router environment snhould work and the [<unknown>] nickname
5916 should appear no more.
5918 The silc_server_replace_id function that receives the Replace ID
5919 payload now sends the NICK_CHANGE notify type also in the file
5920 silcd/packet_receive.c
5922 * Changed WHOIS and IDENTIFY command to support the maximum amount
5923 of arguments defined in protocol specs (3328 arguments). This
5924 fixed a bug that caused problems when there were more than three
5927 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Added extra parameter, command identifier, to the
5930 silc_client_send_command so that explicit command identifier
5933 Changed that ID list routines uses specific command identifier
5934 when sending WHOIS/IDENTIFY requests to the server so that they
5935 can be identified when the reply comes back.
5937 Affected files lib/silcclient/command.[ch],
5938 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5940 * Added `sender' argument to silc_server_packet_send_to_channel
5941 to indicaet the sender who originally sent the packet to us
5942 that we are now re-sending. Ignored if NULL. Affected file
5943 silcd/packet_send.[ch].
5945 * Added some server statistics support in silcd/server_internal.h
5946 SilcServerStatistics structure and around the server code. Also
5947 send some nice statistics information when client is connecting
5950 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Fixed channel ID decoding in server's JOIN command reply in
5953 silcd/command_reply.c
5955 * Fixed braodcasting of replace ID payload to not to send it if
5956 we are standalone server in silcd/packet_receive.c.
5958 * Fixed all channel message sending routines to not to send
5959 packets to clients that has router set, since they are routed
5960 separately in the same function earlier. Affects file
5961 silcd/packet_send.c and all channel packet sending functions.
5963 * In USERS reply, res_argv[i] are not allocated, the table
5964 is allocated. Thus changed that free the table, not its
5967 * In server's whois_check and identify_check if the client is
5968 locally connected do not send any WHOIS commands - they are not
5971 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Fixed some minor bugs in client when sending WHOIS command. The
5974 arguments was in wrong order.
5976 * Removed statis function add_to_channel from server in
5977 silcd/command.c that was previously used with the joining but
5980 * Tested USERS command in router environment successfully with two
5981 routers, two servers and two clients.
5983 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Reorganized the USERS command and command reply in client library
5986 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5987 When the command is given by user we register a pending command
5988 callback that will reprocess the command after the reply has been
5989 received from the server. When reprocessing the packet we then
5990 display the information. Thus, the USERS information is displayed
5991 now in the command callback instead of in the command reply
5992 callback. The processing of the command is same as previously
5993 when server has sent the command reply in the JOINing process.
5995 * Added to USERS command in silcd/command_reply.c to join the client,
5996 we didn't use to know about, to the channel after we've created
5997 a client entry for it. Also, for clienet we did know already still
5998 check whether it is on the channel or not and add it if not.
6000 * Removed silc_server_command_join_notify as the function and its
6003 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Changed the client's pending command handling to the same as the
6006 server's pending command handling. It is also now possible to
6007 execute command reply functions from other command reply
6008 function as the function callbacks for commands and command
6009 replies are one and same. The pending commands are not static
6010 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6011 in client connection context. Thus, pending commands are server
6012 connection specific as it is convenient.
6014 Changed the function silc_client_command_pending and
6015 silc_client_command_pending_del and added new function
6016 silc_client_command_pending_check. Removed the
6017 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6020 * Added cmd_ident, current command identifier, to the client
6021 connection context in lib/silcclient/client.h to keep track on
6022 command identifiers used in command sending. Client's command reply
6023 function handling now supports the mandatory command identifiers.
6025 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6026 funtions in client to fully support pending command callbacks.
6028 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6029 as one of the arguments to the application in the command reply
6032 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6033 before first releasing SILC but came back. Now it is removed again
6034 and should come back nomore. The FORWARDED flag was used only
6035 by the JOINing procedure by forwarding the command packet to router.
6036 Now, the JOINing procedure has been changed to more generic (due
6037 to various router environment issues) and FORWARDED is not needed
6038 anymore for anything. The protocol specification is yet to be
6041 Now, removed silc_server_packet_forward from server and the flag
6042 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6044 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Renamed NAMES command to USERS command. The NAMES was named that
6047 due to historical reasons. Now it is renamed. Also, rewrote
6048 parts of the USERS command. The nickname list is not sent anymore
6049 by the server. Only Client ID and mode lists are sent in the USERS
6050 command. Changed this also to the protocol specification.
6052 The client now resolves the names and stuff after it receives
6053 the USERS list from the server when joining to the channel.
6055 * WHOIS and IDENTIFY commands has been changed to support multiple
6056 Client ID's per command. One can now search for multiple users
6057 in the network by sending only one WHOIS or IDENTIFY command.
6058 Changed the code and the protocol specifications.
6060 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6061 uses silc_server_command_whois_parse to parse the request. */
6063 * If normal server, do not parse the WHOIS and IDENTIFY requests
6064 before sending it to the router. Saves some time.
6066 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Fixed JOIN command on client library. Wrong number of arguments
6069 used to crash the client.
6071 * Added silc_server_channel_has_global function to check whether
6072 channel has global users or not.
6074 * Added silc_server_channel_has_local function to check whether channel
6075 has locally connected clients on the channel.
6077 * The silc_server_remove_from_one_channel now checks whether the
6078 channel has global users or not after given client was removed from
6079 the channel. It also checks whether the channel has local clients
6080 on the channel anymore. If it does not have then the channel entry
6081 is removed as it is not needed anymore.
6083 * The silc_server_notify now checks on JOIN notify whether the joining
6084 client is one of locally connected or global. If it is global then
6085 the channel has now global users on the channel and that is marked
6086 to the channel entry. Also, it now saves the global client to
6087 global list who is joining and JOINs it to the channel. This is
6088 for normal server, that is.
6090 Changed silc_server_send_notify_on_channel,
6091 silc_server_packet_relay_to_channel and
6092 silc_server_packet_send_to_channel check if we are normal server
6093 and client has router set (ie. global client) do not send the
6094 message to that client, as it is already routed to our router.
6096 * Implemented LEAVE notify type handling in silc_server_notify
6099 * Tested LEAVE command in router environment successfully. Tested
6100 with two routers, two servers and two clients.
6104 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6106 * Implemented SIGNOFF notify type handling in silc_server_notify
6109 * silc_server_remove_id now removes the client entry from all channels
6110 it has joined and thusly sends SIGNOFF notify type.
6112 * Rewrote the NAMES list generation in server by removing two excess
6113 loops. The lists are created now inside one loop.
6115 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * silc_server_remove_channel_user checks now also global list
6118 for channel and client.
6120 * silc_server_new_channel_user checks now both local and global
6121 list for channel and client. Fixed a bug in client id decoding.
6122 Used to decode wrong buffer.
6124 * silc_server_channel_message checks now both local and global
6125 list for channel entry.
6127 * Tested channel joining (hence JOIN) in router environment
6128 successfully. Tested with two routers, two servers and two
6131 * Tested channel message sending in router environment successfully.
6133 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Added silc_server_save_channel_key into server.[ch] to save the
6136 received channel key in Channel Key payload processing. It is
6137 also used in JOIN command reply handling.
6139 Equivalent function silc_client_save_channel_key added into
6140 client.[ch] into client library.
6142 * Changed JOIN command reply to send information whether the channel
6143 was created or not (is existing already) and the channel key
6144 payload. Changed protocol specs accordingly.
6146 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6147 the request was sent by ID and not by nickname. Crashed on
6150 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6153 now correctly save the received data.
6155 * silc_server_free_sock_user_data now notifies routers in the
6156 network about entities leaving the network.
6158 At the same time implemented functions silc_server_remove_id
6159 and silc_server_send_remove_id to receive and send REMOVE_ID
6160 packets. The packet is used to notify routers in the network
6161 about leaving entities. The ID removed will become invalid in
6164 * Added function silc_idlist_del_server into server. Removes and
6165 free's server entry from ID list.
6167 * silc_server_private_message function now checks, if we are router,
6168 that the destination ID really is valid ID, naturally.
6170 * In router when NEW_ID packet is received (for new client) the
6171 hash of the Client ID is saved in the ID Cache but the
6172 client->nickname is set to NULL, instead of putting the hash
6175 IDENTIFY command now also checks that client->nickname must be
6176 valid. If it is not if will request the data from the server who
6177 owns the client. Added new function
6178 silc_server_command_identify_check.
6180 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6181 to set the command to already allocated Command Payload.
6183 * Tested private message sending in router environment with two
6184 routers, two servers and two clients. Fixed minor bugs and now
6187 * Fixed segfault from client's NAMES command. Used to crash if
6190 * Forwarded packets must not be routed even if it is not destined
6191 to the receiver. Changed server code comply with this.
6193 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Added `require_reverse_mapping' boolean value to ServerParams
6196 structure. If TRUE (not default) the server will require that
6197 the connecting host has fully qualified domain name.
6199 If the reverse mapping is not required and hostname could not be
6200 found the IP address is used as hostname.
6202 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Implemented version string checking to both client and server.
6205 The check is incomplete currently due to the abnormal version
6206 strings used in development version of SILC.
6208 * Changed all command functions in server to use the new
6211 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Changed char *data to unsigned char *data in ID Cache system to
6214 support binary data as ID Cache data. Changed code to support
6215 binary data in lib/silccore/idcache.c.
6217 * Renamed silc_server_packet_relay_command_reply to
6218 silc_server_command_reply as it is normal packet receiving
6219 function. Rewrote the function to accept command replys for
6220 servers and not only for clients.
6222 * Mark remote router always as registered server if we are connecting
6223 to it. Otherwise, commands sent by the router to us are ignored.
6225 * All ID List find routines now returns the ID Cache Entry pointer
6226 as well if requested.
6228 * WHOIS command works now in router environment, tested with two
6229 routers, two servers and two clients.
6231 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6232 in router environment (as it is almost equivalent to WHOIS) but
6233 hasn't been tested thoroughly. Added new functions:
6235 silc_server_command_identify_parse
6236 silc_server_command_identify_send_reply
6237 silc_server_command_identify_from_client
6238 silc_server_command_identify_from_server
6240 * Disabled route cache adding because adding two different ID's with
6241 same IP replaces the old cache entry thus giving wrong route.
6242 The entry->router->connection is always the fastest route anyway
6243 so route cache may not be needed. Of course, new routes maybe
6244 established after receiving the ID when the entry->router->connection
6245 might not be anymore the most optimal.
6247 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Add route cache for received ID for fast routing.
6251 * Added silc_server_packet_route to route received packet on router
6252 that is not destined to us.
6254 * Renamed silc_server_get_route to silc_server_route_get.
6256 * Added id_string and id_string_len fields into SilcServer to
6257 include encoded ServerID for fast comparing without excess
6258 encoding of the ID's.
6260 * Cleaned up WHOIS command on server side. Added following static
6263 silc_server_command_whois_parse
6264 silc_server_command_whois_check
6265 silc_server_command_whois_send_reply
6266 silc_server_command_whois_from_client
6267 silc_server_command_whois_from_server
6269 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6270 arguments in command replies. All command functions should be
6271 updated to use this macro.
6273 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Minor typo fixes on command reply handling on server.
6277 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * Added silc_server_command_add_to_channel internal routine to add
6280 the client to the channel after router has created the channel and
6281 sent command reply to the server.
6283 * Added generic silc_server_send_command to send any command from
6286 * Use static buffer with ID rendering instead of duplicating data.
6288 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Fixed a channel user mode bug when joining to a channel server gave
6291 everybody channel founder rights, oops.
6293 * We mark ourselves as the router of the incoming server connection
6294 if we are router ourselves. This way we can check in some packet
6295 sending functions whether it is locally connected server. For
6296 incoming router connections we put NULL.
6298 * For router sending packets locally means now always sending the
6299 packet cell wide; to local clients and local servers. For normal
6300 server sending packet locally means sending it to only local
6303 * Fixed the JOIN command to really work in router environment. If the
6304 channel is created it is always created by the router. Router is
6305 also responsible of making the initial joining to the channel,
6306 sending JOIN notify to the sending server and distributing
6307 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6308 does not exist server doesn't do anything else but forward the
6309 command to the router which performs everything.
6311 * Added silc_server_send_channel_key function to send the Channel Key
6314 * Added silc_server_create_channel_key to create new channel key. The
6315 channel key is now re-generated everytime someone joins or leaves
6316 a channel, as protocol dictates. Note: channel->key_len is the
6319 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6322 packet_receive.[ch] to separate packet sending and receiving
6323 routines. The server.[ch] now includes everything else including
6324 actual packet processing (writing and reading data) and other
6327 Renamed silc_server_private_message_send_internal to
6328 silc_server_send_private_message. The routine is still though
6329 used only to relay private messages as server does not send
6330 private messages itself.
6332 Renamed silc_server_new_channel to silc_server_create_new_channel
6333 and added new function sicl_server_new_channel that handles the
6334 incoming New Channel packet. Added also new sending function
6335 silc_server_send_new_channel to send New Channel Payload.
6337 * Added new function silc_server_notify to process incoming notify
6338 packet to the server/router. Server may then relay the notify
6339 to clients if needed.
6341 * Added new function silc_server_new_channel_user to process incoming
6342 New Channel User packet. Router will redistribute the packet and
6343 send JOIN notify to its local clients and locally connected servers
6344 if needed. Normal server will send JOIN notify to its local client
6345 on same channel when received this packet. Added also corresponding
6346 sending function silc_server_send_new_channel_user to sent the
6349 * Added boolean route argument to send_notif_to_channel and
6350 packet_send_to_channel functions to attempt to route the packet
6351 if it is TRUE and send only locally if it is FALSE.
6353 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * silc_server_replace_id now broadcasts the received replace ID
6356 packet if it is not broadcast packet already. The router must
6357 broadcast to inform other routers about changed ID.
6359 * Added backpointer to server's router into SilcServer context in
6360 silcd/server_internal.h.
6362 * Fixed silc_server_packet_broadcast to send correct broadcast
6365 * The channel key is now distributed to the local client as soon
6366 as it is received from the router (in router environment) so that
6367 no other packet may be sent for the channel until client has
6370 * silc_server_remove_channel_user now broadcasts the received
6371 Remove Channel User packet if it is not broadcast packet already.
6372 The router must broadcast to inform other routers about removed
6375 * Added users field into SilcPacketContext that is a reference count
6376 of the context. One can increase the reference count by calling
6377 silc_packet_context_dup which is now changed to just increase the
6378 reference count instead of duplicating the data. The reference
6379 count is decresed by calling silc_packet_context_free that will
6380 free the data after the reference count hits zero.
6382 For now on the packet context and everything allocated into it
6383 (including the raw packet from network) must be freed by calling
6384 the new silc_packet_context_free function. Added also new function
6385 silc_packet_context_alloc that must be used now to allocate the
6386 context. This also means that if a routine is asynchronous from
6387 silc_[client/server]_packet_parse_type the packet context must
6388 be duplicated by calling silc_packet_context_dup. Otherwise it
6389 gets free'd after silc_[client/server]_packet_parse_type returns.
6390 Also, one must remember that if packet is duplicated then its
6391 reference count must be decresed by calling the free function as
6392 many times as it was duplicated.
6394 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6395 from both client and server.
6397 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Made joining to a channel working in router environment.
6401 * Cleaned up JOIN command on server side and create function
6402 silc_server_command_join_channel internal routine to make the
6405 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6407 * Changed silc_command_pending list to SilcDList. Also, added
6408 `ident' field to SilcServerCommandPending structure to identify
6409 the reply and to call correct callback.
6411 Added silc_server_command_pending_check function to replace the
6412 corresnponding macro. The silc_command_pending list is not
6415 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6416 to set identifier to previously allocated Command Payload. It
6417 is used to set identifier for command when resending Command
6420 * Added silc_command_payload_encode_payload to encode Command
6421 Payload buffer from SilcCommandPayload structure.
6423 * Added silc_argument_payload_encode_payload to encode Argument
6424 payload buffer from SilcArgumentPayload structure.
6426 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Changed WHOIS command to support router connection on server side.
6429 The whois request is always sent to router unless the server is
6430 standalone server. After server has received the reply from the
6431 router will it send the reply to the client.
6433 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6434 broadcast received broadcast packet. The function is used only
6435 by router. The broadcast packet is always sent to the router's
6438 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6439 render given ID to printable string, for log files for example.
6441 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Made basic router to router connections working. At least they
6444 can now connect to each other but nothing really works the way
6445 they are supposed - yet.
6447 * Added new initiator token to RouterConnection configuration
6448 file in silcd/serverconfig.[ch]. It is used to tell whether we
6449 are the initiator to the remote router or whether we'll expect
6450 the other end to connect.
6452 * Moved registering of listener task to silc_server_init, hence
6453 the server starts listenning as soon as it is run, even if it
6454 does not have connections to other routers. Let's see how well
6457 * Changed default connection retry timeouts for more suitable in
6460 * Removed cipher and such arguments from silc_idlist_add_client
6461 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6462 Added new function silc_idlist_add_data to add the keys and stuff
6465 * Added SilcIDListData structure and added it to SilcClientEntry
6466 and SilcServerEntry as their first field in the structure. This
6467 way we can explicitly cast the ID entries to the SilcIDListData
6468 structure and get common data for the entries. In past, we had
6469 to first check what type of connection it is and then cast it to
6470 correct ID entry type. Now, we can directly cast the opaque
6471 pointer to the SilcIDListData (no matter what ID entry it actually
6472 is) and get the data needed.
6474 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6477 in some circumstances even if threre were timeout tasks, though not
6478 IO tasks, but tasks anyway. Now fixed.
6480 * Defined SilcServerConnection structure to hold connection specific
6481 stuff about directly connected servers and routers. The definition
6482 is currently in silcd/server_internal.h. I thought about having
6483 a bit more important role fro this struct but for now it is used
6484 only when connecting to other server (or router actually).
6486 * Added connecting retry support in server when connecting to
6487 router(s). The retry feature implement exponential backoff
6488 algorithm. Also, added SilcServerParams structure to hold default
6489 parameters for server. For now, it include these retry settings
6490 and are hard coded. After server is moded to be as Silc Server
6491 Library this structure will be more important.
6493 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Changed client librarys channel->clients table to SilcList and
6496 changed code accordingly.
6498 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Changed client's channel table to SilcList and changed code
6501 accordingly. Also changed SilcChannelClientEntry to include back-
6502 pointer to the channel so that client entry can use that structure
6503 as list as well and we have fast cross-reference to the channel.
6504 This change dramatically decreased the complexity of channel
6505 handling with client entry and vice versa (removed one extra
6506 loop when searching for channel entry from many functions).
6508 * Changed server->sim from table to SilcDList and changed code
6511 * NAMES command can now be used from user interface. It will show
6512 the user list on the channel, neatly.
6514 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6515 Code now saves realname of the user if it becomes available.
6517 * Renamed configure.in to configure.in.pre and made ./prepare
6518 script to automatically add correct version string to
6519 configure.in which it creates from configure.in.pre.
6521 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * NAMES command reply now shows users mode with the nickname when
6526 * Moved silc_client_ch[u]mode[_char] functions from
6527 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6528 place sucks, they are utility functions and should be in some
6531 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6533 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6536 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6540 * Added TRQ (efficient deque and list library) into lib/trq. This is
6541 a very good list library that is currently used in the SILC. Defined
6542 SilcList API over the library because I didn't like the API very
6543 much. See lib/trq/silclist.h for the API and examples of how to
6544 use the API. Fixed various places in the code to use the new
6545 SilcList API. The SilcList is meant for lists that has a structure
6546 already defined as a list. It is not suitable to add just some
6547 context to the list (in TRQ, the context is the list actually).
6549 So, I defined SilcDList that can be used for the purpose where
6550 predefined list structure does not exit. This can be used as
6551 such list. Now some context just can be added to the SilcDList.
6552 Currently this list is not used in the SILC just yet, though there
6553 are a lot places where this can replace dynamically allocated
6554 tables and I will fix these places, later, to use SilcDList.
6555 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6556 and use TRQ internally).
6558 Also fixed some annoying warning messages that the original TRQ
6559 code generated. Also minor changes to TRQ's Makefile.in.
6561 * Added support for querying by Client ID to both WHOIS and
6562 IDENTIFY commands into server, as required by the protocol.
6564 * Removed method function pointers from SilcBuffer structure. They
6565 weren't used to anything and just increased the context size for
6566 no good reason. This change also made silc_buffer_alloc and
6567 silc_buffer_free functions inline functions.
6569 * Disabled command flooding detection support until it's fixed so
6570 that it accepts commands in but does not execute them more than once
6573 * Added silc_net_localhost(), to return local hostname, into
6574 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6575 that must be initialized before calling silc_client_init.
6577 * Added new function: silc_server_send_notify_on_channels to send
6578 notify messages to all channels client has joined. It is assured
6579 that the message is sent only once per client.
6581 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6582 lib/silcutil/silcutil.[ch] as silc_format function. The new
6583 function is generic and is used by server as well, not only by
6584 the logging routines.
6586 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6587 the provided version string was not acceptable. Added new function:
6588 silc_ske_check_version into lib/silcske/silcske.h. The function
6589 must be implemented by the application (client or server) and it
6590 does not reside in the SKE library. The function checks the version
6591 string remote end sent.
6593 * Added back pointers (to opaque context and to SilcSocketConnection)
6594 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6596 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6597 duplicate packet context structure.
6599 * Changed `notify' client operation to send same arguments as client
6600 receives from server except for ID's. ID's are mapped to correct
6601 ID entry and that is returned. Also, if channel entry is not sent
6602 by server but the notify is for channel the channel entry is sent
6603 to application (otherwise application doesn't know that it is for
6604 channel (library gets it from packet's Destination ID)).
6606 * Added silc_client_remove_from_channels into client library to
6607 remove a client from all channels it has joined to. Used when
6608 received SIGNOFF notify from server. Added also new function
6609 silc_client_replace_from_channels to replace old ID entry with
6610 new ID entry on all channels. Used when received NICK_CHANGE
6613 * Fixed ID Cache list handling in silc_idlist_get_client in
6614 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6615 to get (or query) client by ID.
6617 * Updated TODO list.
6619 * Added connection authentication status message defined by the
6620 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6621 support for these into the code in client and server side.
6623 * Added generic function silc_client_send_command to send any command
6624 with variable argument list. Application should use this function
6625 to send commands if the command functions provided by the library
6626 does not suite for the application's user interface needs.
6628 * Added new `failure' client operation. Application is notified about
6629 received failure packet if client is executing a protocol. In this
6630 case the protocol's execution has failed.
6632 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6633 is required by the protocol.
6635 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6636 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6639 * Added status flag to SilcSKE object to indicate realtime status
6640 of the SKE protocol.
6642 * Application receives now exactly same command reply arguments as
6643 the library receives from server. However, if ID is received the
6644 corresponding ID entry is returned to the application (eg. Client
6645 ID is mapped to correct SilcClientEntry entry and that is returned).
6646 Changed command_reply client operation due to this change.
6648 * Changed all ID's in commands and in command replys as ID Payloads.
6649 Change affected both client and server side codes.
6651 All ID's sent in SILC network (with execption of ID's in SILC
6652 Packet header) are sent in ID Payload to support variable length
6655 * Server now notifies nick changes and notifies all clients on
6656 the channels about the new nickname (about the new Client ID,
6659 * Implemented CMODE command to change channel modes. Supports all
6660 channel modes defined by the protocol specs except ban and invite
6661 lists. (Also, private channel key mode is supported but support for
6662 setting private channel key in client is missing, thus, this mode
6663 has no effect on client side (except that server requires that the
6664 client uses private channel key and normal channel traffic does not
6667 Also, invite mode works per se, but INVITE command does not work
6668 yet correctly, so you can set channel as invite only channel but
6669 inviting clients to the channel does not work (it is yet to be
6670 thought what's the best way to do it).
6672 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6673 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6674 Implemented CUMODE command to change user's mode on the channel.
6675 Supports all modes defined by the protocol specs.
6677 * Added NAMES command reply to return users modes on the channel.
6679 * Removed unnecessary and slow ciphers from lib/silccrypt.
6681 * Set SO_KEEPALIVE option to connection sockets by default.
6683 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6685 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6686 redefined the Notify Payload into protocol specs.
6688 * Added silc_id_payload_parse_id to get ID directly from raw
6691 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6693 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6694 accept searching by Client ID as well.
6696 * Added support for LEAVE and SIGNOFF notify types in client library.
6698 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6699 to parse ID Payload from raw data.
6701 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Added flags parameter into silc_ske_assemble_security_properties
6704 function in lib/silcske/silcske.[ch].
6706 * Changed notify client operation to fit better for notify messages
6707 sent by server. The notify payload received from server is now
6708 passed to the application (after parsing it to SilcNotifyPayload).
6709 It is application's responsibility to retrieve the arguments
6710 from the payload and show the message the way it wants. The message
6711 sent by server is implementation specific.
6713 * Changed public keys to comply with the protocol specification.
6714 Old public keys are not supported anymore and are not compatible.
6716 * Removed nickname from Channel Payload as the latest draft removed
6717 it. The client must resolve the nickname from the NAMES command
6718 reply received when it joined the channel.
6720 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6722 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Fixed some errors in protocol specification drafts.
6726 * Created lib/silccore/silcnotify.c to implement Notify Payload
6727 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6728 generic payloads described by protocol specifications. The file
6729 includes implementations for ID Payload and Argument Payload.
6731 * Changed Command Payload implementation to use the new Argument
6732 Payload. Changed command_xxxx_payload to command_payload_xxxx
6733 to comply with SILC coding conventions.
6735 * Added suppport for Argument Payload handling in Notify Payload
6736 implementation as protocol requires it. Added the new support
6737 into server and client lib as well.
6739 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Added support for multiple nicknames on same channel. [n] is
6742 added locally to the nickname if there are more than one same
6743 nicknames on the channel.
6745 * Server now sends all nicknames that matched WHOIS request.
6746 Client also shows the list received from server.
6748 * Added TOPIC command to client side. User can now set and show
6749 current topic on channel.
6751 * Added MOTD command to client and server. Also, server sends the
6752 motd when client connects to the server.
6754 * Changed version strings to comply ISO 8601.
6756 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Fixed protocol error handling in client library. It should now
6759 cope even if the SKE fails for some reason.
6761 * Made new protocol specification drafts for submitting to IETF.
6763 * Implemented TOPIC command to server in silcd/command.c.
6765 * Added two new notify types into lib/silccore/silcnotify.h:
6766 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6767 notify nickname change and topic setting/change on a channel.
6769 * API change of command_reply operation in client library. The
6770 application gets now the status type received from server as well.
6772 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6776 * Cras fixed and optimized the packet handling even further and
6777 it should work now. Minor change to the prototype of function
6778 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6780 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Added new function into lib/silcutil/silcschedule.[ch]:
6783 silc_schedule_with_fd to select() a specified fd. The function
6784 returns after timeout expires or data arrives or goes. The
6785 function is used by packet routines to wait that all data is
6786 received from network.
6788 * Fixed data reading from network in lib/silccore/silcpacket.c.
6789 The code now assures that all data is read from the fd and then
6790 continues packet processing. This was a bug fix since the code
6791 used to drop some data in some circumstances.
6793 * Added new function into lib/silcclient/client.[ch]:
6794 silc_client_start_key_exchange to start key exchange after
6795 connection has been established to server. The code internally
6796 now uses this funtion but its main purpose was to provide it
6797 for applications that perform their own connecting. After
6798 application has created a connection it merely calls this
6799 function to start the key exchange between client and server.
6800 The library takes care of everything else after that.
6802 Updated also lib/silcclient/README to explain the usage of
6805 * Do not send to application information that connection has
6806 been established. Application gets notified it by connect
6809 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6811 * Applied cras's patch to add silc_schedule_one function. The
6812 function runs scheduler once and returns.
6814 * Fixed the scheduler after cras messed it up. The timeout
6815 handling works now as it's supposed to work.
6817 * Added into lib/silccore/ silcnotify.h to include notify
6818 message types support. Changed silc_server_send_notify*
6819 functions, in server.[ch], to support those new notify types.
6820 Added the support for the notify types into client library,
6821 as well. Added new notify client operation into ops.h in
6824 * Changed silc_server_packet_send_to_channel to send normal
6825 packets instead of just channel message packets. The function
6826 is now used to send the notify packets to channels. It is not
6827 used to send channel message packets anymore, as server never
6830 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6831 va_arg()s as it seems to require it nowadays. I guess, if SILC
6832 is compiled with older va_arg() the new code should work anyway.
6834 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Splitted core library. Core library (lib/silccore) includes
6837 now only SILC protocol specific core (and common) components.
6838 Created new utility library (lib/silcutil) that includes more
6839 generic purpose stuff. The stuff for util library was taken
6840 from the old core library. This was minor and easy split.
6842 * Created SILC Client Library (lib/silcclient) that includes
6843 implementation of the SILC client without user interface. This
6844 was major move from silc/ directory. The code has been changed
6845 so that it is transparent towards the user interface. The
6846 silc/ directory includes now the same user interface as before
6847 and it uses the new client library. Read lib/silcclient/README.
6848 Basicly, the client library performs everything else related
6849 to SILC except user interface handling. Also, configuration
6850 files are considered to be part of user interface and library
6851 does not handle them.
6853 This change also changed a lot of structures, function naming etc.
6854 Most important change was that SilcClientWindow object was
6855 renamed to SilcClientConnection in the client library. Created
6856 also new file lib/silcclient/ops.h. Also added new files
6857 silc/local_command.[ch] and silc/client_ops.[ch].
6859 All these changes were made to make it easier for user interface
6860 designers to create what ever user interface for the SILC client
6863 It is also expected that the server will be moved to lib
6864 directory as well and SILC Server Library will be created;
6865 sometimes in the future.
6867 * Removed Local commands from lib/silccore/silccommand.h as
6868 they are application specific and new client library does not
6869 handle any of those anymore.
6871 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6872 old client implementation in silc/.
6874 * Added support for callback functions in SILC_LOG_* macros.
6875 Application can now set its own callbacks that will be called
6876 instead of using the default functions that will always print
6877 the debug messages to stderr (or stdout). Also, debugging can
6878 now be disabled by setting silc_debug to FALSE and re-enabled by
6879 setting it to TRUE. Note, that logging will still work even
6880 if debugging is disabled.
6882 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6883 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6884 silc_log_reset_debug_callbacks.
6886 * To enable debugging in silc client one must give now -d
6887 option on command line.
6889 * Changed silc_schedule_init to automatically allocate task queues
6890 if they are not allocated before calling it.
6892 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Added GMP 3.1 into math library.
6896 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6898 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6899 a channel in SILC network. The packet is used by servers and
6900 routers to notify other routers that user has left a channel.
6901 This little feature was missing until now. Added the feature
6902 to protocol specification as well.
6904 Added functions: silc_server_send_remove_channel_user and
6905 silc_server_remove_channel_user into server.[ch].
6907 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6908 lib/silccore/silcpacket.h. However, they are not implemented
6911 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Fixed joining to a channel and sending channel messages
6914 between server and router. The channel message sending should
6915 now work inside a cell.
6917 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Fixed the private message sending between server and router.
6920 The private message sending should now work inside a cell.
6922 * Added silc_server_replace_id into server.[ch] to replace
6923 existing ID in the SILC network.
6925 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6926 and silc_idlist_replace_server_id into idlist.[ch] in server.
6928 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Fixed the server to server connections. Server can again now
6931 connect to router. Router to router connections probably does
6934 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Added dynamic protocol registering support. Now protocols can
6937 registered and unregistered on the fly. Patch by cras.
6939 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Added lib/contrib directory to hold routines that some platforms
6942 don't have but are needed by SILC.
6944 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6945 into lin/contrib to provide getopt() and getopt_long() for
6946 those who don't have it.
6948 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added AWAY command to client. When away message is set and
6951 client receives a private message packet the client automatically
6952 replies to the sender with the away message.
6954 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6955 bug seemed to be the cause of recent problems when compiling
6958 * Added version detection support to SKE protocol specification
6959 and added the new changes to the SKE implementation as well.
6960 There were other minor changes in the SKE protocol as well.
6962 Many changes in lib/silcske/silcske.[ch] and in
6963 lib/silcske/payload.[ch].
6965 * Added ^U functionality, clear input line. Patch from cras.
6967 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6969 * Mainly small bugfixes on core library. Fixed some debugging
6970 logging and buffer overflow in silclog.c.
6972 * Updated config.sub and config.guess on the distribution tree.
6974 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Added command lagging support in server. Client may execute
6977 commands now only once in two seconds.
6979 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Optimized packet reception. MAC computation and checking is now
6982 also more optimized. A lot previously duplicated code is now
6983 used as generic by both client and server.
6985 * Fixed key pair generation in clientutil.c
6987 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6989 * Added into lib/silccore/silcbufutil.[ch] new function;
6990 silc_buffer_realloc.
6992 * Moved generic packet sending/encryption functions to
6993 lib/silccore/silcpacket.[ch] from client and server. Some
6994 rewriting of the functions.
6996 * Moved all generic packet reception/decryption functions to
6997 lib/silccore/silcpacket.[ch] from client and server. The
6998 packet processing is now much cleaner in both client and server.
6999 These were major changes in both client and server.
7001 * Created many common functions in server to do packet sending.
7002 Previously code were duplicated a lot, this has been removed
7005 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Rewrote major parts of the ID cache system. Don't know
7008 whether it is better now or not but at least the API is more
7011 * Major rewrite on ID cache stuff on client because of the ID
7012 cache API changes. Added idlist.c to client.
7014 * Also major rewrite on ID cache stuff on server as well.
7015 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7016 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7017 in hand, instead they are all put into the ID cache system now.
7018 All server_idlist_* routines uses ID cache now instead of
7019 traversing its own lists (those lists does not exist anymore).
7020 SilcIDList though still exists. Also, SilcXXXEntry's are

7025 * Finally made the SKE implementation compliant to the protocol
7026 specification. All mp integers are now binary encoded as
7027 opposed being HEX encoded.
7029 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7032 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7033 functions: silc_[encode/decode]_pem. Also added function
7034 silc_encode_pem_file to PEM encode with newlines ('\n') for
7037 * SILC public keys are now encoded either PEM or binary. Same
7038 option is for private keys as well. By default private keys
7039 are binary encoded and public keys PEM encoded. Silly HEX
7040 encoding were removed.
7042 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7043 function to create fingerprints.
7045 * Fixed a bug in SHA1; does not change the original data anymore.
7047 * Partly implemented INFO command on client and server side.
7048 Fixed CLEAR command. Changes to SERVER command; show current
7049 server(s) when giving command without arguments. Added
7050 VERSION command to client.
7052 * Added check to server that unregistered connections cannot
7053 execute commands (unless it is specificly allowed).
7055 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Fixed screen refresh.
7059 * Fixed channel joining bug from client. On some circumstances
7060 client tried to join to a channel it had already joined.
7062 * Added public key verification process into client's protocol.c.
7063 The client now verifies the public key from user and saves
7064 it into ~./silc/serverkeys/ directory.
7066 Added into: clientutil.[ch]: silc_client_verify_server_key.
7068 * Changed SKE protocol's silc_ske_initiator_finish function
7069 to accept callback function that verifies the received public
7070 key. Removed old silc_ske_verify_public_key function.
7072 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7075 silc_pkcs_private_key[_data]_set.
7077 * Made the password and public authentication more cleaner in
7078 server's protocol.c.
7080 * Removed historic and obsolete protocol `channel_auth' from
7081 both client and server.
7083 * Removed wrong way of sending command status messages from
7084 server to client in server's command.c. The old way violated
7085 protocol specification.
7087 Changes to silccore/silccommand.[ch]: removed
7088 silc_command_encode_status_payload -> not needed anymore,
7089 changed silc_command_encode_payload_va to accept extra
7090 argument on variable argument list. The argument type must
7091 now be provided to the function. Also, added new function:
7092 silc_command_encode_reply_payload_va which is same as
7093 normal command_encode_payload_va except command status type
7094 is provided as extra argument.
7096 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Added ~./silc directory handling. The directory includes the
7099 public and private keys for the client.
7101 Added silc_client_check_silc_dir, silc_client_create_identifier
7102 and silc_client_load_keys.
7104 * Implemented SILC protocol compliant public key. Added public
7105 and private key saving to and loading from files.
7107 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7108 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7109 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7110 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7111 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7113 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7114 silc_pkcs_load_[public/private]_key.
7116 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Added silc_server_get_route (route.[ch]) to get connection
7119 data for the fastest route for given ID.
7121 * Implemented INVITE command on client and server. The command
7122 were re-defined in the SILC Protocol Specification and the
7123 implementation now complies with the specification.
7125 * Implemented PING command on client and server.
7127 * Implemented NAMES command on client and server. The server side
7128 supports currently only normal server not router server yet.
7129 Some changes to NAMES definition in SILC protocol specification.
7131 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7133 * Implemented LEAVE command on client and server.
7135 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7136 again. This change was made to the protocol as well. Server
7137 should not violate the protocol specification anymore.
7139 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7142 was tested. SOCKS4 was not but should work anyway.
