54 the SKE interface a bit.
56 * Fixed padding problem in PKCS#1. The padding was not actually
57 random since the random number generator was used incorrectly.
58 This security bug affects only when encrypting with PKCS#1, and
59 it is not currently used at all in SILC. SILC only use signing
60 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
62 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

129 keepalive_secs, reconnect_count, reconnect_interval,
130 reconnect_interval_max, reconnect_keep_trying and
131 require_reverser_lookup. Added ConnectionParam block, and
132 implemented the connection parameters when connecting as
133 initiator and when accepting connections as responder.
135 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
136 whether given configuration value has been given already.
138 Affected files silcd/serverconfig.[c], server.[c].
140 * Splitted the doc/example_silcd.conf.in. Separated the crypto
141 algorithm parts and created new file silcalgs.conf, that
142 is now included from the example_silcd.conf.in.
144 * Optimized the silc_server_connect_to_router_second to take
145 the connection configuration object from the SilcServerConnection
146 object instead of finding it during the connecting phase.
147 Added the configuration object to SilcServerConnection struct.
148 Affected files silcd/server_internal.h, server.c.

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

228 hash algorithm. Affected file lib/silccrypt/silcrng.c.
230 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
232 * Fixed the file transfer's key agreement payload to include
233 zero port also if the hostname is NULL because it could not
236 Call file transfer monitor callback now also if error occurs
237 during key agreement protocol.
239 Changed the silc_client_file_send interface to return the
240 SilcClientFileError instead of session id. The session ID
241 is returned into pointer provided as argument.
243 Check that the file exists locally before sending the
244 file transfer request at all.
246 Affected file lib/silcclient/client_ftp.c, silcapi.h.

258 file lib/silcutil/silclog.c.
260 * Fixed the channel message payload decryption in the function
261 silc_channel_message_payload_decrypt to not modify the original
262 buffer before it is verified that the message decrypted
263 correctly. Otherwise, next time it is called with correct
264 channel key it won't encrypt since the payload is corrupted.
265 Affected file lib/silccore/silcchannel.c.
267 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

304 silc_client_replace_channel_id, and removed functions
305 silc_client_new_channel_id and silc_idlist_get_channel_by_id
308 * Added cross reference of the joined channels to the
309 SilcClientEntry, and changed the SilcChannelEntry's
310 users list to SilcHashTable. The affected files are
311 lib/silcclient/idlist.[ch].
313 * Fixed a bug in hash table tarversing. While the hash table
314 is traversed with SilcHashTableList the table must not be
315 rehashed. It is now guaranteed that auto rehashable tables
316 are not rehashed while tarversing the list. Also defined that
317 silc_hash_table_rehash must not be called while tarversing
318 the table. Added function silc_hash_table_list_reset that must
319 be called after the tarversing is over. The affected files are
320 lib/silcutil/silchashtable.[ch].
322 * Changed all hash table traversing to call the new
323 silc_hash_table_list_reset in server and in client library.
325 * Added function silc_client_on_channel to return the
326 SilcChannelUser entry if the specified client entry is joined
327 on the specified channel. This is exported to application as
328 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
330 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
332 * Fixed founder regaining problem with JOIN command on normal
333 server. The notify for mode change must be sent always and
334 not only if !cmd->pending. Affected file silcd/command.c.
336 * Fixed the WHOWAS command's reply sending to support the
337 lists correctly. Affected file silcd/command.c.
339 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
341 * When sending JOIN command to router for processing the
342 sender's old command identifier was not saved back to the
343 sender's command context, fixed now. The affected file is
346 * Create the key in JOIN command of the router did not return
347 the channel key, added check for this. Affected file is
350 * Fixed a channel ID update bug in JOIN command reply. Do
351 not directly upgrade the ID but call the function
352 silc_idlist_replace_channel_id if the ID was changed.
353 Affected file silcd/command_reply.c.
355 * Fixed memory leaks from command calling if it would fail.
356 Affected file silcd/command.c.

368 * Removed TRQ from lib/trq, not needed anymore.
370 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
371 with server connections. Later this will be configurable
372 in config file after new config file is done. Affected file
375 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
377 * Fixed a crash in server related to channel announcements.
378 Affected file silcd/server.c.
380 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
382 * Fixed memory leaks in silc_server_create_new_channel*
383 functions. Affected file silcd/server.c.
385 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
386 which ID was changed. This way the router will send the
387 user list for the channel again, and server won't be in
388 desync in some rare circumstances. Affected file is
389 silcd/packet_receive.c.
391 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

420 file silcd/packet_receive.c and silcd/command.c.
422 * Fixed the SERVER_SIGNOFF notify handling on normal server
423 not to save the history information for clients. Same was
424 fixed earlier in remove_clients_by_server function, but not
425 here. Affected file silcd/packet_receive.c.
427 * Raised the default connection-retry count from 4 to 7 in
428 server. Affected file silcd/server.h.

446 * Fixed some double frees from client library commands.
447 Affected file is lib/silcclient/command.c.
449 * Fixed CUMODE command in server to assure that no one can

451 little bug. Affected file silcd/command.c.
453 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Removed the SilcClientCommandDestructor from the client
456 libary, it is not needed anymore. Affected files are
457 lib/silcclient/silcapi.h, command[_reply].[ch],
458 client_notify, idlist.c.
460 * Fixed GETKEY command to first resolve client, and then
461 resolve the server only if the client was not found, instead
462 of resolving both at the same time. Affected file is
463 lib/silcclient/command.c.
465 * Added silc_client_start_key_exchange_cb and lookup the
466 remote hostname and IP address before starting the key
467 exchange with server. The affected file is
468 lib/silcclient/client.c.
470 * The server's public key is now saved using the IP address
471 of the server and not the servername for the filename.
472 The hostname public key filename is checked as an fall back
473 method if the IP address based filename is not found.
475 Fixed the GETKEY command to save the fetched server key
478 Print the remote server's hostname now when new key is
479 received during connection process. Affected file is
480 irssi/src/silc/core/client_ops.c.
482 * Return always our own public key to the client if it asks
483 for it with GETKEY command. Affected file silcd/command.c.
485 * Removed the use_auto_addr variable from default config
486 file since it was in wrong section. Affected file is
489 * Fixed TOPIC_CHANGE notification to not route it when it
490 was sent using silc_server_send_notify_to_channel function.
491 Affected file silcd/command.c.
493 * Fixed silc_server_send_notify_kicked to send the kicker's
494 Client ID also, it was missing. Affected files are
495 silcd/command.c, silcd/packet_send.[ch].
497 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
499 * Do not save client history information in SERVER_SIGNOFF.
500 Fixes the bug in normal server that it does not detect
501 the client becoming valid after the server becomes back
502 online. Affected file silcd/server_util.c.
504 * Added `sock_error' field into the SilcSocketConnection
505 context. When error occurs during socket operation (read
506 or write) the error is saved. Added also new function
507 silc_socket_get_error to return human readable socket error
508 message. Affected files are lib/silcutil/silcsockconn.[ch],
509 lib/silcutil/unix/silcunixsockconn.c, and
510 lib/silcutil/win32/silcwin32sockconn.c.
512 * The server now prints the socket error message in the
513 signoff for client. Affected file silcd/server.c.
515 * Fixed the `created' channel information sending from router
516 to server in JOIN command. Checks now whether the channel
517 really was created or not and set it according that.
519 Fixed the JOIN command to use the client entry's current
520 ID during the joining procedure instead of the one it sent
521 in the command (it is checked though), since it can change
522 between the packet processing and command processing, and
523 would just case unnecessary pain in the client end. Affected
524 file silcd/command.c.
526 * Fixed a channel key payload sending to use correct channel
527 ID when the server was forced to change the channel's ID by
528 router. Router sent the key payload with the old Channel ID.
529 Affected file silcd/packet_receive.c.
531 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
533 * Call silc_server_save_channel_key only if the key payload
534 was provided in the JOIN command's command reply. Affected

537 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
539 * Fixed silc_mp_sizeinbase to return the value correctly with
540 MPI. Affected file lib/silcmath/mp_mpi.c.
542 * Fixed the stop_server signal to correctly stop the scheduler
543 and gracefully stop the server when SIGTERM or SIGINT signals
544 are received. Affected file silcd/silcd.c.
546 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
548 * Simple handling of TERM and HUP signals. Also added some log
549 flushing call around. Affected file is
552 * Fixed small bugs in silclog.c. Now buffering output will take
553 effect after 10 seconds since startup: This will ensure that
554 no important startup messages are lost. Also output redirection
555 will preserve original format ([Date] [Type] message).
556 Affected file is lib/silcutil/silclog.c.
558 * Added two options to the config file, in the logging section:
559 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
560 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
562 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
564 * Do not print the warning about log files not being initialized
565 more than once to avoid excess logging. Affected file is
566 lib/silcutil/silclog.c.
568 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
569 the SIM copying in make install in Makefile.am.pre.
571 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
573 * Rewritten silclog APIs. Globally interesting changes follows:
574 silc_log_set_files() changed to silc_log_set_file().
575 silc_log_set_callbacks() changed to silc_log_set_callback().
576 ROBOdoc documented silclog header file.
577 SilcLogCb now returns bool to wether inihibit the default
578 handler or not (to keep the old behaviour return always TRUE).
579 The new APIs should also fix the problem of the
580 silcd_error.log file that was written in the current directory.
583 Log files streams will remain opened after silc_log_set_file()
584 call, means less CPU usage notably on high traffic servers.
585 File streams are now full buffered, and flushed to the disk
586 every 5 minutes, lesses HD activity and CPU usage.
587 Messages can be redirected, allowing admins to configure
588 one single logfile for all server messages.
589 the silc_log_quick global variable to activate fast-logging.
590 Affected files lib/silcutil/silclog.[ch]
592 * Changed some code to conform new silclog APIs. Affected
593 files are doc/example_silcd.conf.in, silcd/server.c
594 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
597 * Fixed a memory leak that could occur in some situations.
598 Affected file silcd/serverconfig.c.
600 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
602 * Added the silc_client_del_client to remove the client from
603 all channels as well. Affected file lib/silcclient/idlist.c.
605 * Fixed the client library to correctly remove the client
606 from all channels when the client entry is being destroyed.
607 Affected file lib/silcclient/client_notify.c, command.c.
609 * Added auto-nicking support to the client library. If the
610 applicatio now sets client->nickname it will be sent to the
611 server after connecting by the library. This way for example
612 SILCNICK (or IRCNICK) environment variables will have effect
613 and always change the nickname automatically to whatever
614 it is wanted. Affected file lib/silcclient/client.[ch].
616 * Renamed silc_server_command_bad_chars to the
617 silc_server_name_bad_chars and moved it to the
618 silcd/server_util.[ch]. Added also new function
619 silc_server_name_modify_bad to return nickname that
620 includes bad characters as new nickname without those
621 bad characters. This check and modify is now used in
622 silc_server_new_client when the username is initially set
623 as nickname, so it must be checked to be valid nickname.
624 Affected file silcd/packet_receive.c.
626 * The nickname length is now taken from the packet for real
627 and not trusted to strlen() since it clearly can return
628 wrong length for nickname including bad characters. This
629 also applies to channel names. Affected file silcd/command.c.
631 * Removed the lib/silcsilm/modules directory. Modules are now
632 compiled into the lib/silcsim. Fixed the copying of the
633 modules to follow symbolic links in Makefile.am.pre.
635 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
637 * Fixed silc_string_regexify list creation. Fixes bugs with
638 BAN and INVITE commands in server. The affected file is
639 lib/silcutil/unix/silcunixutil.c.
641 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Removed the command destructor entirely from the server's
644 command and command reply routines. It is not needed, and
645 its usage was buggy and caused crashes. Affected files are
646 silcd/command[_reply].[ch].
648 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
650 * Cancel protocol and NULL sock->protocol if timeout
651 occurred during protocol. Affected file silcd/server.c.
653 * Cancel protocol timeouts always before calling the final
654 callback, to assure that after final callback is called
655 no other state will be called for the protocol anymore.
656 Affected file silcd/protocol.c.
658 * Print error log if incoming connection configuration could
659 not be found. Affected file silcd/server.c.
661 * Fixed JOIN command to correctly save the founder mode
662 to the client on normal SILC server, when the channel
663 was created by the router. Affected file silcd/command.c.
665 * Fixed LIST command (hopefully) to send correct reply
666 packets. Affected file silcd/command.c.
668 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
670 * The silc_packet_receive_process now returns FALSE if the
671 read data was invalid packet, and TRUE if it was ok.
673 The server now checks that if unauthenticated connection
674 sends data and its processing fails the server will close
675 the connection since it could be a malicious flooder.
677 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
679 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
681 * Make sure the warning about error opening a log file is
682 printed only once and not everytime it fails (produces
683 too much useless log). Affected file lib/silcutil/silclog.c.
685 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
687 * Made the silc_server_daemonise() function more readable.
688 Affected file silcd/server.c.
690 * Pid file is now optional, the user may comment it out from
691 the config file. Removed define SILC_SERVER_PID_FILE, we
692 don't need a default any longer. Affected file
693 configure.in.pre, lib/Makefile.am.pre.
695 * Make some use of the pid file. The server now dies at startup
696 if it detects a valid pid file on his path. The server would
697 die anyway in this circumstance, because of the bind() failure.
698 Affected file silcd/silcd.c.
700 * No longer compiling lib/dotconf.
702 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Fixed JOIN command parsing not to crash. Affected file
705 lib/silcclient/command.c.
707 * Fied the NICK_CHANGE notify to add the new client entry
708 even it is resolved. This removes an <[unknown]> nick
709 thingy bug in the client. Affected file is
710 lib/silcclient/client_notify.c.
712 * Do not try to allocate 0 bytes (efence does not like it)
713 in lib/silccore/silccomand.c when encoding payload.
715 * Do not take IRCNICK as nickname in Irssi SILC client since
716 it is not possible to set nickname before hand connecting
717 the server (TODO has an entry about adding auto-nicking
720 * Changed the silc_server_command_pending to check whether
721 there already exists an pending entry with the specified
722 command, command identifier and pending callback. This is
723 to fix IDENTIFY and WHOIS related crashes that may register
724 multiple pending commands with same identifier. Affected
725 file silcd/command.c.
727 * Fixed the server to reconnect to the router even if it
728 was already reconnecting and EOF was received. This to
729 fix a possibility that the server wouldn't ever try to
730 auto-reconnect to the router. Affected file silcd/server.c.
732 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
734 * Fixed the server's password authentication to use the
735 length of the locally saved password, and not the one
736 sent in the packet. Affected file silcd/protocol.c.
738 * Fixed same password authentication problem in the
739 Authentication Payload handling routines in
740 lib/silccore/silcauth.c.
742 * Yet another password authentication problem fixed with
743 channel password handling in silcd/command.c.
745 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
747 * If first character of string in silc_parse_userfqdn is '@'
748 then do not parse it. Affected file is
749 lib/silcutil/silcutil.c.
751 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
753 * Fixed minor bug in IDENTIFY command reply sending, which
754 caused various weird problems during JOIN when it was
755 resolving names for users. Affected file silcd/command.c.
757 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
759 * Fixed the IDENTIFY command reply sending to chech better valid
760 clients. It was possible to send incomplete list of replies.
761 Affected file silcd/command.c.
763 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Added silc_client_command[s]_[un]register functions now to
766 dynamically register the commands in client library. Removed
767 the static table of commands. This allows the client library
768 to call commands without causing the application to know about
769 what commands library has called.
771 Removed the INFO command reply kludge to detect when the command
772 was called by library. Now library use its own command reply
773 function for INFO command.
775 Added function silc_client_command_call to call a command.
776 Application can use it to call command, not access the structure
779 Now all commands that are sent by the client library (not
780 explicitly sent by application) use own command reply functions.
782 Affected files around lib/silcclient/ and in
783 irssi/src/silc/core/.
785 * Fixed the WHOIS command reply sending to chech better valid
786 clients. It was possible to send incomplete list of replies.
788 Fixed the WHOIS and IDENTIFY to send the request to router
789 if normal server did not do it and did not find any results.
791 Affected file silcd/command.c.
793 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
795 * Moved the internal data from SilcClient context into its
796 own file, not accesible to application. Affected files
797 lib/silcclient/client.h and lib/silcclient/client_internal.h,
798 and other files in client library.
800 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
802 * Added doc/examples installation target in Makefile.am.pre.
805 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
807 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
808 commands the found client entry will be removed from the
809 cache, after notifying application about the error. Affected
810 file lib/silcclient/command_reply.c.
812 * Changed the /MSG to check for exact nickname user gave, and
813 not let `nick' match `nick@host' if it is only one found. Now,
814 user must type the exact nickname (like nick@host2) even if
815 there are no more than one same nicks found. This is to avoid
816 a possibility of sending nickname to wrong nickname since
817 `nick' could match `nick@host'. Affected file is
818 irssi/src/core/silc-servers.c.
820 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
822 * Do not print "you are now server operator" or similar when
823 giving /away command. Affected files are
824 irssi/src/silc/core/client_ops.c, silc-servers.h.
826 * Made the silc_server_command_pending_error_check to send
827 the same command reply payload it received back to the
828 original sender of the command. This way all arguments
829 that was received by the server will be received by the
830 client too. Affected file silcd/command.c.
832 * Added the silc_idcache_add to return the created cache entry
833 to a pointer. Affected file lib/silccore/silcidcache.[ch].
835 * Add global clients to expire if they are not on any channel.
836 This is because normal server will never know if they signoff
837 if they are not on any channel. The cache expiry will take
838 case of these entries. This is done by normal servers only.
839 The affected files are silcd/command_reply.c,
840 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
842 * If server receives invalid ID notification for WHOIS or
843 IDENTIFY and the ID exists in the lists, it is removed.
844 Affected file silcd/command_reply.c.
846 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
847 in client then client entry that it matches is searched and
848 the nickname is printed on the screen for user. Affected
849 file irssi/src/silc/core/client_ops.c.
851 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Use cache entry expire time in the LIST command reply to
854 purge old entries from the cache after the LIST command
855 reply has been received. This way we don't have non-existent
856 entries in the cache for too long. Affected file is
857 silcd/command_reply.c.
859 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
861 * If we are normal server, and we've not resolved client info
862 in WHOIS or IDENTIFY from router, and it is global client,
863 we'll check whether it is on some channel. If it is not
864 then we cannot be sure about its validity and will resolve it
865 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
866 file silcd/command.c.
868 * Search channel by name (if possible) rather than by ID
869 in IDENTIFY command's command reply. Affected file is
870 silcd/command_reply.c.
872 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
874 * Distribute to the channel passphrase in CMODE_CHANGE notify.
875 Updated specs and implemented it. Affected file silcd/command.c,
876 silcd/packet_send.c and silcd/packet_receive.c.
878 * Implemented the <founder auth> payload handling in the JOIN
879 command. If provided all conditions for channel joining
880 except requirement to provide correct passphrase can be
881 overrided by the channel founder. Updated the protocol specs.
882 Affected file silcd/command.c.
884 Added support for founder auth in JOIN command in client
885 library. Fixed the parsing of the JOIN command now to support
886 all options as they should be. The affected file is
887 lib/silcclient/command.c.
889 * Optimized the WHOIS and IDENTIFY commands to send the request
890 to router only if it includes nicknames or other names. If
891 they include only IDs then check the local cache first before
892 routing. Affected file is silcd/command.c.
894 * Added channels topic announcements. Affected file is
895 silcd/packet_receive.c and silcd/server.c.
897 * Fixed the silc_server_send_notify_topic_set to really destine
898 the packet to channel. Affected file silcd/packet_send.c.
900 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
901 library. Affected file lib/silcclient/client_notify.c.
903 * Added UMODE announcements. Affected file silcd/server.c.
905 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Memory leak fixes in:
909 lib/silcutil/silcsockconn.c
910 lib/silcske/silcske.c
913 lib/silccrypt/silcpkcs.c
914 lib/silccore/silccommand.c
915 lib/silccore/silcidcache.c
920 * ROBOdoc documented the lib/silcske/groups.h file and a
921 bit changed the interface for better.
923 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
925 * Update the client entry context in the ID cache after
926 nick change. Affected file lib/silcclient/command.c.
927 Fixes the CUMODE command when regaining founder privileges,
928 and a little WHOIS problem.
930 * Fixed silc_net_gethostbyname to correctly call the
931 inet_ntop. Affected file lib/silcutil/silcnet.c.
933 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
935 * Added IPv6 support checking to the configure.in.pre, added
936 also --enable-ipv6 option to override the check. Affected
937 file configure.in.pre.
939 * The silc_thread_create now calls the start function
940 directly if threads support is not compiled in. Removes
941 ugly #ifdef's from generic code. Affected files are
942 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
944 * Added silc_net_gethostby[name/addr]_async to asynchronously
945 resolve. Affected files are lib/silcutil/silcnet.[ch].
947 * Added support for rendering IPv6 based server, client and
948 channel IDs. Affected file lib/silcutil/silcutil.c.
950 * Added support for creating IPv6 based server IDs. Affected
951 file is silcd/serverid.c.
953 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
955 * Added silc_net_gethostby[addr/name] into the
956 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
957 routines. Added silc_net_is_ip[4/6]. Affected file is
958 lib/silcutil/unix/silcunixnet.c. All routines that take
959 address as argument now supports both IPv4 and IPv6 addresses.
961 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
963 * Fixed LIST command reply sending in server. Affected file
966 * Server now sends the kicker's client ID in the KICK notify
967 to the kicked client. Affected file silcd/command.c.
969 * The client library now parses the kickers client ID and
970 UI displays it. Affected files lib/silcclient/client_notify.c
971 and irssi/src/silc/core/silc-channels.c, module-formats.c.
973 * Made all payload parsing function prototypes consistent.
974 They all take now const unsigned char * and uint32 pair as
975 the payload data instead of SilcBuffer. Changes all around
976 the source tree. Other unsigned char* -> const unsigned char*
977 changes around the tree as well.
979 * Optimized SFTP client and server packet sending not to
980 allocate new buffer for each packet but to recycle the
981 first allocated buffer. Affected files are
982 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
984 * Optimized the SFTP client to use SilcList instead of
985 SilcDList for requests, because it is faster. Affected file
986 is lib/silcsftp/sftp_client.c.
988 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
989 into lib/silccore/silcid.[ch].
991 Renamed silcpayload.[ch] into silcargument.[ch].
993 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
995 * If client entry is deleted with active key agreement
996 session, abort the session.
998 The silc_client_abort_key_agreement now calls the completion
999 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1001 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1004 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Don't use __restrict in older GCC's. Affected file is
1007 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1009 * silc_net_localhost now attempts to reverse lookup the
1010 IP/hostname. Affected file lib/silcutil/silcnet.c.
1012 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1013 command. It can be used to gain founder privileges at
1014 the same time when joining the channel.
1016 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1017 kicker's client ID as well. Updated protocol specs.
1019 Defined that the server must send SILC_COMMAND_IDENTIFY
1020 command reply with error status to client who sent
1021 private message with invalid client ID.
1023 Updated the protocol specification.
1025 * Added silc_server_send_command_reply to send any
1026 command reply. Affected file silcd/packet_send.[ch].
1028 * Added silc_id_payload_encode_data to encode ID payload
1029 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1031 * The server now send IDENTIFY command reply with error
1032 status if client ID in private message is invalid. Affected
1033 file silcd/packet_receive.c.
1035 * Save the server key file with server's IP address in
1036 the filename instead of hostname. The affected file is
1037 irssi/src/silc/core/client_ops.c.
1039 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1044 * Added libtool support for compiling shared objects in
1045 lib/silcsim. Affected file configure.in.pre and
1046 lib/silcsim/Makefile.am. Original patch by cras.
1048 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Pid file configuration, and server's config file fixes
1051 patch by toma. Updated CREDITS file.
1053 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Fixed silc_client_channel_message to not try to decrypt
1056 the message twice if it resolved the destination client
1057 information. This could cause of dropping one channel
1058 message. Affected file lib/silcclient/client_channel.c.
1060 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1063 lib/silcclient/client.c. This function is used when the SILC
1064 Client is run under some other scheduler, or event loop or
1065 main loop. On GUI applications, for example this may be
1066 desired to used to run the client under the GUI application's
1067 main loop. Typically the GUI application would register an
1068 idle task that calls this function multiple times in a second
1069 to quickly process the SILC specific data.
1071 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1073 * Fixed silc_server_drop() for dropping the supplementary
1074 groups as well, this could cause a security hole on some
1077 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1082 * Write PID file after dropping privileges. Added -F option
1083 to run server on foreground. A patch by debolaz.
1084 Affected files silcd/server.c, silcd/silcd.c.
1086 * Fixed MOTD to return the MOTD file server name. Affected
1087 file silcd/command.c.
1089 * Added INFO command reply handling to the Irssi SILC Client.
1090 Affected file irssi/src/silc/core/client_ops.c.
1092 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Fixed the silc_idcache_list_* routines to really support
1095 the dynamic list. Fixes a crash. Affected file is
1096 lib/silccore/silcidcache.c.
1098 * Fixed the LIST command reply to really call LIST command's
1099 pending callbacks. Affected file silcd/command_reply.c.
1101 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Update conn->local_entry->nickname after giving NICK
1104 command. Affected file lib/silcclient/command.c.
1106 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1108 * Added the [pid] option to the silcd configuration file
1110 Affected files: serverconfig.[ch] and silcd.c
1112 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1114 * Save fingerprint in WHOIS command reply in server.
1115 Affected file silcd/command_reply.c.
1117 * Fixed NICK commands pending callback registration.
1118 Affected file lib/silcclient/command.c.
1120 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Use ++server->cmd_ident when sending commands in server,
1123 instead of random number. Affected file silcd/command.c.
1125 * Fixed GETKEY command reply to call actually GETKEY pending
1126 command callbacks. Affected file silcd/command_reply.c.
1128 * A bit stricter check for nicknames. Check for same nickname
1129 in NICK command also. Affected file silcd/command.c.
1131 * Do not call INFO command everytime client ID changes, only
1132 during first connecting. Affected file lib/silcclient/client.c.
1134 * Set the new nickname only after successful command reply for
1135 NICK command is returned by server. Affected file
1136 lib/silcclient/command.c.
1138 * Remove nicknames from nicklist during server_signoff notify.
1139 Should fix /NAMES bit more. The affected file is
1140 irssi/src/silc/core/silc-channels.c.
1142 * Added `fingerprint' field to the SilcIDListData in the
1143 silcd/idlist.h to hold the fingerprint of the client's
1146 Send the fingerprint of the client's public key in WHOIS
1149 Affected files silcd/command.c, and silcd/idlist.[ch].
1151 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1152 create fingerprint from given data.
1154 * Show the fingerprint of the client's public key in WHOIS.
1155 Affected files irssi/src/module-formats.[ch] and
1156 irssi/src/silc/core/client_ops.c.
1158 * Format the multiple same nicknames also during JOIN and
1159 NICK_CHANGE notifys. Affected file is
1160 lib/silcclient/client_notify.c.
1162 * Do not print error on screen for invalid private message
1163 payload since it can come if someone is sending private
1164 messages with wrong key. Affected file
1165 lib/silccore/silcprivate.c.
1167 * Fixed multiple concurrent /PING crash. Affected file
1168 lib/silcclient/command.c.
1170 * Changed the wrong ID encoding. All IP addresses must be
1171 in MSB first order in encoded format. They were encoded
1172 wrong and was in LSB format. Affected files are
1173 silcd/serverid.c, lib/silcutil/silcutil.c.
1175 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1177 * Call the `connect' client operation through the scheduler
1178 in case of error. Affected file lib/silcclient/client.c.
1180 * Call the `failure' client operation even if the error
1181 occurred locally during a protocol. Affected file is
1182 lib/silcclient/protocol.c.
1184 * Added support of sending LIST command to router from normal
1185 server. This way normal server can get list of all channels
1186 in the network too. Fixed the channel list sending in the
1187 server too. Affected files are silcd/command.c, and
1188 silcd/command_reply.[ch].
1190 * Added silc_server_update_channels_by_server and
1191 silc_server_remove_channels_by_server. They are used during
1192 disconnection of primary router and in backup router protocol.
1193 Affected file silcd/server_util.[ch], silcd/server.c and
1194 silcd/server_backup.c.
1196 * Fixed channel adding to global list in IDENTIFY command
1197 reply in server. Affected file silcd/command_reply.c.
1199 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * If the incoming packet type is REKEY or REKEY_DONE process
1202 that packet always synchronously. Fixes yet another MAC
1203 failed error on slow (dialup) connections. Affected file
1204 lib/silcclient/client.c and silcd/server.c.
1206 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Call check_version SKE callback for initiator too. Affected
1209 file lib/silcske/silcske.c.
1211 * Implemented fix for security hole found in the SKE that was
1212 fixed in the specification few days back; the initiator's
1213 public key is now added to the HASH value computation.
1214 Added backwards support for the old way of doing it too, for
1215 old clients and old servers. Affected file is
1216 lib/silcske/silcske.c.
1218 * Enabled mutual authentication by default in SKE. If initiator
1219 is not providing mutual authentication the responder will
1220 force it. This will provide the proof of posession of the
1221 private key for responder. The affected files are
1222 lib/silcclient/protocol.c and silcd/protocol.c.
1224 * Do not cache anymore the server's public key during SKE.
1225 We do mutual authentication so the proof of posession of
1226 private key is done, and if the server is authenticated in
1227 conn auth protocol with public key we must have the public
1228 key already. Affected file silcd/protocol.c.
1230 * Added new global debug variable: silc_debug_hexdump. If
1231 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1232 file lib/silcutil/silclog.[ch].
1234 * Fixed compilation warning due to char * -> const char *.
1235 Affected files lib/silcutil/silcnet.h, and
1236 lib/silccore/silcauth.[ch].
1238 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Fixed CMODE command when new channel key was created. If
1241 the creation failed the old key was removed. Next time giving
1242 same command would crash the server since the old key was
1243 freed already. Affected file silcd/command.c.
1245 * Fixed the silc_server_announce_get_channels to not crash
1246 on reconnect. Affected file silcd/server.c.
1248 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Added silc_log_set_debug_string function to set a regex
1251 string to match for debug output. Only the function names,
1252 or filenames matching the given debug string is actually
1253 printed. This way it is possible to filter out those debug
1254 strings that user is not interested in.
1256 Fixed a bug in silc_string_regexify.
1258 Affected files lib/silcutil/silclog.[ch], and
1259 lib/silcutil/unix/silcunixutil.c.
1261 * Changed the -d options in both server and Irssi SILC client
1262 to take the debug string as argument. Affected files
1263 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1265 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Added silc_hash_babbleprint to create a Bubble Babble
1268 Encoded fingerprint. The encoding is developed by Antti
1269 Huima (draft-huima-babble-01.txt), and it creates human
1270 readable strings out of binary data. Affected file
1271 lib/silccrypt/silchash.[ch].
1273 * Print the babble print now in addition of fingerprint as well
1274 in Irssi SILC client. Affected files are
1275 irssi/src/fe-common/silc/module-formats.[ch],
1276 irssi/src/fe-common/silc/core/client_ops.c.
1278 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Fixed a security problem found in SKE. The initiator's
1281 public key too is now added to the HASH hash value creation
1282 which is signed by the responder to create the SIGN value.
1283 This will prevent anyone in the middle to lie to the responder
1284 about the initiator's public key. If this is done now, the
1285 man in the middle will get caught. Updated the protocol
1288 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Better installation directory handling. Configure module
1291 paths and other paths automatically to example_silc* files
1292 in doc/. A patch by toma.
1294 * Fixed compiler warning from MPI library, and from SILC RNG.
1297 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1298 It can be configured with ./configure. A patch by toma.
1300 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Find correct make to use in prepare-clean. A patch by
1303 toma. Affected file prepare-clean.
1305 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1307 * Added irssi variables use_auto_addr, auto_bind_ip,
1308 auto_bind_port and auto_public_ip.
1310 * Changed the interface for silc_client_send_key_agreement
1311 in lib/silcclient/silcapi.h
1315 irssi/src/silc/core/silc-core.c
1317 lib/silcclient/silcapi.h
1318 irssi/src/silc/core/silc-channels.c
1319 lib/silcclient/client_keyagr.c
1322 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1324 * Added silc_pkcs_public_key_compare to compare two
1325 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1327 * Check that the client who set the founder mode on the
1328 channel is the same client that is giving the founder
1329 mode to itself. It is done by comparing the saved public
1330 key (it is saved even in the authentication is passphrase).
1331 Affected file silcd/command.c.
1333 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Do not process packet for disconnected socket connection.
1336 Affected file lib/silccore/silcpacket.c.
1338 * Process the DISCONNECT packet through scheduler in the
1339 client library. Affected file lib/silcclient/client.c.
1341 * Fixed the silc_client_packet_parse to not to increase
1342 the packet sequence number if the conn->sock and the
1343 current socket connection is not same. This can happen
1344 for example during key agreement when the conn includes
1345 multiple socket connections (listeners). Affected file
1346 lib/silcclient/client.c.
1348 * The sender of the file transfer request now provides also
1349 the pointer (listener) for the key exchange protocol. If
1350 the listener cannot be created then it sends empty key
1351 agreement and lets the receiver provide the listener.
1353 Added `local_ip' and `local_port' arguments to the
1354 silc_client_file_send. If they are provided they are used,
1355 if not then it will attempt to find local IP address, if
1356 not found or bind fails then the remote client will provide
1359 Affected files are lib/silcclient/client_ftp.c and
1360 lib/silcclient/silcapi.h.
1362 * Extended the FILE SEND command to support defining the
1363 local IP and port for key exchange listener. They are
1364 optional. Affected file irssi/src/silc/core/silc-servers.c.
1366 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Defined to WHOIS command reply the sending of fingerprint
1369 of the client's public key (if the proof of posession of the
1370 corresponding private key is verified by the server).
1371 Updated to the protocol specification.
1373 * Added support of receiving the client's public key's
1374 fingerprint in command reply in client library. Affected
1375 file is lib/silcclient/command_reply.c, and
1376 lib/silcclient/idlist.[ch].
1378 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Do not send over 128 chars long nickname to the server
1381 in NICK command. Affected file lib/silcclient/command.c.
1383 * Do not send over 256 chars long channel names to the server
1384 in JOIN command. Affected file lib/silcclient/command.c.
1386 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Assure that silc_server_close_connection cannot be called
1389 twice for same socket context. Affected file is
1392 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1394 * Send error message to application if opening file for
1395 writing during file transfer fails. Affected file is
1396 lib/silcclient/client_ftp.c.
1398 Remove all file transfer sessions for a client that we're
1399 removing from ID cache.
1401 Affected file is lib/silcclient/client_ftp.c.
1403 * Fixed silc_net_addr2bin to return correct address. Affected
1404 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1406 * Fixed file transfer session removing on signoff notify.
1407 Affected file irssi/src/silc/core/silc-servers.c.
1409 * Added the SilcClientFileError to be returned in the monitor
1410 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1411 Affected file lib/silcclient/silcapi.h.
1413 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Fixed a crash in silc_client_ftp_free_sessions and
1416 silc_client_ftp_session_free_client. Affected file
1417 lib/silcclient/client_ftp.c.
1419 * Added `disabled' field in the SilcChannelEntry in the server
1420 to indicate if the server entry is disabled. Affected file
1421 silcd/idlist.h, silcd/command[_reply].c.
1423 * SILC server adds now /var/run/silcd.pid everytime it is
1424 started. Affected file silcd/silcd.c.
1426 * Added silc_server_packet_send_clients to send a packet to
1427 the provided table of client entries. Affected file

1430 * Fixed a crash in client resolving in client_prvmsg.c in
1431 client library. Affected file lib/silcclient/client_prvmsg.c.
1433 * Do not actually remove the client directly from ID cache
1434 during SERVER_SIGNOFF, but invalidate it. This way we
1435 preserve the WHOWAS info for the client. Affected file
1436 silcd/server_util.c.
1438 * Fixed SERVER_SIGNOFF notify handling in the server. The
1439 server is now able to process incoming SERVER_SIGNOFF notify
1440 for a server that it doesn't even know about. It will remove
1441 the clients provided in the notify. Affected file
1442 silcd/packet_receive.c.
1444 * Check for partial packet in data queue after every packet that
1445 was found from the queue. Return and wait for more data if
1446 there is partial data in queue. Affected file is
1447 lib/silccore/silcpacket.c.
1449 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Added SilcClietFileError enum to indicate error in
1452 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1453 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1454 Affected files lib/silcclient/silcapi.h and
1455 lib/silcclient/client_ftp.c.
1457 * Check that newsize in silc_buffer_realloc is larger than
1458 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1460 * Added better monitor of file transfers. It now monitors
1461 key agreement protocol during the file transfer too. Added
1462 error reporting too. Affected files
1463 irssi/src/silc/core/silc-servers.c,
1464 irssi/src/fe-common/silc/module-formats.[ch].
1466 * Wrote a help file for FILE command.
1468 * Added silc_rng_global_get_byte_fast to get not-so-secure
1469 random data as fast as possible. Random data is read from
1470 /dev/urandom if available and from the SILC RNG if not
1471 available. It is used in padding generation. Affected file
1472 lib/silccrypt/silcrng.[ch].
1474 * All packets in client library are now processed synchronously.
1475 Optimized packet processing a lot. Affected file
1476 lib/silcclient/client.c.
1478 * All server connection packets are processing synchronously
1479 now in server, to optimize packet processing. Affected file
1482 * Include files are installed now only in Toolkit distribution
1483 if make install is given. Affected files: all Makefile.am's.
1485 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Assure that silc_client_notify_by_server_resolve does not
1488 resolve the client information multiple times. If it cannot
1489 be found by the first it cannot be found at all. Affected
1490 file lib/silcclient/client_notify.c.
1492 * Fixed WHOWAS command reply calling. Affected file
1493 lib/silcclient/command_reply.c.
1495 * Removed all references to silc_idlist_get_client from the
1496 Irssi SILC client since that call is internal call used by
1497 the library. The Irssi SILC client will use now client
1498 retrieval functions found in silcapi.h.
1500 * Fixed a bug in resolving nickname info before sending
1501 private message. It used freed memory. Affected file
1502 irssi/src/silc/core/silc-servers.c.
1504 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Assure my_channels statistics cannot go negative in server.
1507 Affected files silcd/server.c, silcd/server_util.c.
1509 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1513 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Win32 Toolkit changes. Affected files
1516 win32/silc.dsw, win32/libsilc/libsilc.def,
1517 win32/libsilcclient/libsilc.def,
1518 lib/silcutil/silcutil.c, and
1519 lib/sftp/sftp_fs_memory.c.
1521 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Added silc_net_localip to return local host's IP address.
1524 Affected file lib/silcutil/silcnet.[ch].
1526 * If key exchange or rekey protocol is active for a connection
1527 parse all packets syncronously since there might be packets
1528 in packet queue that we are not able to process without first
1529 processing packets before them. Affected file silcd/server,
1530 lib/silcclient/client.c.
1532 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1533 whether library should continue processing the packet.
1534 Affected file lib/silccore/silcpacket.h.
1536 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1537 SilcSFTPMonitorData to SFTP server to monitor various
1538 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1539 lib/silcsftp/sftp_server.c.
1541 * Added silc_file_size to return file size. Affected file

1546 transmission. Affected file lib/silcclient/client_ftp.c,
1547 lib/silccilent/client.[ch].
1549 * Added new local command FILE to the Irssi SILC Client.
1550 It is used to perform the file transfer. It has subcommands
1551 SEND, RECEIVE, SHOW and CLOSE. Affected files
1552 irssi/src/silc/core/client_ops.c,
1553 irssi/src/silc/core/silc-server.[ch].
1555 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Relay the SILC_PACKET_FTP in the server. Affected files
1558 silcd/server.c and silcd/packet_receive.c.

1562 * Renamed silc_file_read and silc_file_write to functions
1563 silc_file_readfile and silc_file_writefile. Added function
1564 silc_file_open and silc_file_close. Affected files
1565 lib/silcutil/silcutil.[ch].
1567 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Resolve the client info when received private message or
1570 channel message for a client which nickname we don't know.
1571 Affected files lib/silcclient/client_prvmsg.c and
1572 lib/silcclient/client_channel.c.
1574 * Do not crash in /KEY if client is not connected. Affected
1575 file irssi/src/silc/core/silc-channels.c.
1577 * Added SilcClientStatus field to the SilcClientEntry in the
1578 lib/silcclient/idlist.h.
1580 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1581 is incomplete and is being resolved, it won't be resolved
1584 Make sure also that USERS command reply does not resolve
1585 twice information. Affected file is
1586 lib/silcclient/command_reply.c.
1588 Make sure that silc_client_get_clients_by_list does not
1589 resolve twice same information.
1591 * Check for valid client->id in the silc_server_free_client_data.
1592 Affected file silcd/server.c.
1594 * Fixed /GETKEY nick@server not to crash if the server entry
1595 is not found. Affected file lib/silcclient/command.c.
1597 * Fixed the silc_server_check_cmode_rights to check the
1598 requested modes correctly. Affected file silcd/command.c.
1600 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Better checks for non-printable chars in nick added.
1603 Affected file silcd/command.c.
1605 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1607 * Call the silc_server_udpate_servers_by_server in the
1608 primary router that comes back online in the backup resuming
1609 protocol. Otherwise it routes packets wrong. Affected file
1610 silcd/server_util.[ch], silcd/server_backup.c.
1612 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1615 lib/silcutil/silcbuffmt.[ch].
1617 * Redefined the SILC packet header to include the padding
1618 length. Affected file lib/silccore/silcpacket.[ch].
1620 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1621 length for maximum padding up to 128 bytes). Affected
1622 file lib/silccore/silcpacket.h.
1624 * Removed all backwards support for old 0.5.x MAC thingies.
1625 The SILC packet header change makes it impossible to be
1626 backwards compatible.
1628 * Send the ENDING packet with timeout in the backup resuming
1629 protocol. This is to assure that all routers has connected
1630 to the primary router. Affected file silcd/server_backup.c.
1632 * Changed the RNG to take the first IV from random data. It
1633 used to take it from zero actually. Changed the RNG also
1634 to use /dev/urandom during session. /dev/random is used
1635 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1637 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * Changed the SILC packet header to have the first two bytes
1640 (the packet length) encrypted. Affected files aroung the
1641 code tree, lib/silccore/silcpacket.[ch]. Removed the
1642 SilcPacketCheckDecrypt callback. It is not needed anymore
1643 since the silc_packet_receive_process will determine now
1644 whether the packet is normal or special.
1646 * Implemented the unidirectional MAC keys. Affected files
1647 lib/silcske/silcske.c, silcd/protocol.c and
1648 lib/silcclient/protocol.c.
1650 * Implemented the packet sequence number to the MAC computation.
1651 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1652 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1653 lib/silcclient/protocol.c.
1655 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * Allow backup router to announce servers. All servers
1658 announced by backup router are added to the global list
1659 automatically. Update hte server's socket to our primary
1660 router also when backup router announces a server.
1661 Affected file silcd/packet_receive.c.
1663 * Do not update the client->router in the function
1664 silc_server_udpate_clients_by_server if the client is on
1665 global list. We might fail to find any specific server
1666 for locally connected clients and local cell clients. They
1667 should still use the `from' and not `to' as client->router.
1668 This fixes backup router resuming protocol. Affected file
1669 silcd/server_util.c.
1671 * Decrease channel statistics count only if the channel
1672 deletion worked. Affected files are silcd/server.c and
1673 silcd/server_util.c.
1675 * Added silc_server_update_servers_by_server to update origin
1676 of all server entries. Used during backup router protocol.
1677 Affected files silcd/server_util.[ch], silcd/server.c. and
1678 silcd/backup_router.c.
1680 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1681 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1682 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1683 lib/silccrypt/silchmac.c.
1685 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Assure that router cannot reroute the same channel message
1688 to the sender. Affected file silcd/packet_receive.c.
1690 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Made better checks that the channel message is not sent
1693 to the router it came from. Affected file is
1694 silcd/packet_send.c. Fixed memory leak too.
1696 * Announce informations for incoming router connection, but
1697 only after checking if it is replaced by backup router.
1698 Affected file silcd/packet_receive.c.
1700 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed the backup resuming protocol to work in multiple
1703 router environment. Affected file silcd/server_backup.c.
1705 * Route packet only to one router in the function
1706 silc_server_packet_send_to_channel. Affected file is
1707 silcd/packet_send.c.
1709 * Fixed silc_server_send_notify_dest to set the broadcast
1710 flag. Fixed the silc_server_send_notify_topic to actually
1711 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1712 Affected file silcd/packet_send.c.
1714 * Changed the SFTP Filesystem interface. Changed the
1715 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1716 the filesystem operation function. The SilcSFTPFilesystem
1717 is now a context that is allocated by all filesystem allocation
1718 functions and it already includes the operations structure
1719 and filesystem specific context. It is given as argument
1720 now to the silc_sftp_server_start. This made the interface
1721 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1722 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1724 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Changed the backup router adding and getting interfaces
1727 in the server. The router that will be replaced by the
1728 specified backup router is now sent as argument. Affected
1729 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1732 * Added silc_net_addr2bin_ne to return the binary form of
1733 the IP address in network byte order. Affected files
1734 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1736 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Check for existing server ID in silc_server_new_server
1739 and in silc_server_connect_to_router_final and remove the
1740 old entry if it exists. Affected file silcd/packet_receive.c,
1743 * Send the channel message always to only one router, either
1744 in upstream or downstream. Affected file is
1745 silcd/packet_send.c.
1747 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * Wrote the definition of the backup resuming protocol to the
1750 protocol specification.
1752 * Removed one redundant channel key generation from normal
1753 server during joining procedure. Removed one redundant
1754 channel key sending from server to router during joining
1755 procedure. Affected file silcd/command.c.
1757 * Made minor bugfixes to the backup router resuming protocol.
1758 Affected file silcd/server_backup.c, server.c.
1760 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Added --disable-asm configuration option. Affected files
1763 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1766 * Implemented the backup resuming protocol that is used to
1767 resume the primary router position in the cell after the
1768 primary router comes back online. Affected files
1769 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1770 and silcd/server_util.[ch].
1772 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Sleep two (2) seconds after sending QUIT command to server.
1775 Affected file lib/silcclient/command.c.
1777 * Assure that if outgoing data buffer is pending do not force
1778 send any data. Affected file silcd/packet_send.c.
1780 * Assure that if outgoing data buffer is pending do not force
1781 send any data. Affected file lib/silcclient/client.c.
1783 * Implemented the backup router support when the primary router
1784 goes down. The servers and routers can now use the backup
1785 router as new primary router without loosing connectivity.
1787 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1789 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1790 in the server to indicate disabled entry. All data read
1791 from the connection will be ignored and no data is sent
1792 for entry that is disabled. Affected files are
1793 silcd/idlist.h, silcd/server.c.
1795 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * Created SFTP client and server test programs in the
1798 lib/silcsftp/tests directory.
1800 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Implemented memory filesystem (virtual filesystem) for
1803 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1806 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Implemented the SFTP (SSH File Transfer Protocol) to the
1809 lib/silcsftp. It includes SFTP client and SFTP server
1812 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Moved lib/silccore/silcprotocol.[ch] to the
1815 lib/silcutil library.
1817 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1818 take variable argument list pointer as argument. Affected
1819 file lib/silcutil/silcbuffmt.[ch].
1821 * Added silc_buffer_set function that is used to set data
1822 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1823 Affected file lib/silcutil/silcbuffer.h.
1825 * Changed various routines in the core library to use the new
1826 silc_buffer_set instead of allocating new buffer only for
1829 * Added 64-bit value formatting and unformatting support to the
1830 silc_buffer_[un]format routines. Affected file is
1831 lib/silcutil/silcbuffmt.[ch].
1833 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1834 to includes/bitmove.h.
1836 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Fixed channel user mode saving in client library. Affected
1839 file lib/silcclient/command[_reply].c.
1841 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Defined the file transfer to the SILC Protocol. Added
1844 new packet type SILC_PACKET_FTP and defined File Transfer
1845 Payload. The mandatory file transfer protocol is SFTP
1846 (SSH File Transfer Protocol). Affected file in addition
1847 of the internet draft is lib/silccore/silcpacket.h.
1849 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1850 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1851 is used as part of backup router protocol when the primary
1852 router of the cell is back online and wishes to resume
1853 the position as primary router.
1855 * Redefined the MAC generation keys in the protocol. The
1856 same key is not used anymore in both direction. Both
1857 direction will now use different keys for sending and
1858 receiving. This fixes a potential security flaw. This
1859 change causes incompatibilities in the protocol.
1861 * Redefined also the MAC computation from the packet.
1862 An packet sequence number is now added to the MAC
1863 computation. This prevents possible replay attacks against
1864 the protocol. This change too causes incompatibilities
1867 Added `sequence' field to the SilcPacketContext to hold
1868 the current sequence number for the packet.
1870 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Added `created' field to the SilcIDListData in the file
1873 silcd/idlist.h to indicate the time when the entry was
1876 * Added `created' field to the SilcChannelEntry too. Affected
1877 file silcd/idlist.h.
1879 * Added `creation_time' aguments to all the announcement functions
1880 in the server. If it is provided then only the entries that
1881 was created after the provided time frame are actually
1882 announced. Affected file silcd/server.[ch].
1884 * The protocol says that the Channel ID's IP address must be
1885 based on the router's IP address. Added check for this in
1886 the silc_server_new_channel when processing incoming New Channel
1887 Payload. Affected file silcd/packet_receive.c.
1889 * Print out the correct version with --version in SILC client.
1890 Affected file irssi/src/silc/core/silc-core.c.
1892 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Fixed WHOWAS command to check for completnes of the client
1895 entry always, not just when the command is coming from client.
1896 Affected file silcd/command.c.
1898 * Added new function silc_server_packet_queue_purge to purge the
1899 outgoing data queue to the network. After the function returns
1900 it is guaranteed that the outgoing packet queue is empty.
1901 Affected file silcd/packet_send.[ch].
1903 * Purge the outgoing packet queue in the rekey protocol's final
1904 callback to assure that all rekey packets go to the network
1905 before quitting the protocol. Affected file silcd/server.c.
1907 * Added silc_client_packet_queue_parse as similar function as
1908 in server to the client library. The affected file is
1909 lib/silcclient/client.c.
1911 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Splitted silcd/server.c and created silcd/server_util.[ch]
1914 for utility functions.
1916 * Added new socket flag SILC_SF_DISABLED to indicate that the
1917 connection is open but nothing can be sent to or received from
1918 the connection. Affected file lib/silcutil/silsockconn.[ch].
1919 The checking for disabled socket is checked in the low level
1920 silc_socket_write and silc_socket_read functions.
1922 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Allow only nicknames and channel names that fits into the
1925 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1927 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * When processing JOIN command reply in server check that if
1930 the channel exists in our global list we'll move it the local
1931 list. Affected file silcd/command_reply.c.
1933 * Fixed the check whether client is joined on the channel already
1934 in JOIN command. Affected file lib/silcclient/command.c.
1936 * Fixed the JOIN command reply to check whether the channel
1937 already exists. Affected file lib/silcclient/command_reply.c.
1939 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Added silc_ske_status_string to map the SKE error numbers
1942 to readable strings. The affected files are
1943 lib/silcske/silcske[_status].[ch].
1945 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Do not show the private channels on the WHOIS channel list
1948 as it is not allowed by the protocol. The affected file is
1951 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Assure that the packet length digged from the actual packet
1954 is something sensible in the silc_packet_decrypt_rest_special
1955 in lib/silccrypt/silcpacket.c.
1957 * Free and NULL the allocated pointer in silc_hmac_alloc if
1958 the HMAC allocation fails. The affected file is
1959 lib/silccrypt/silchmac.c.
1961 * Print the selected security properties to the log files in
1962 the server. Affected file silcd/protocol.c.
1964 * Add SKE's reference counter even if calling the completion
1965 callback manually. Otherwise it goes negative, although it
1966 does not cause any problems. The affected file is
1967 lib/silcske/silcske.c.
1969 * Remove the client entry with short timeout after giving the
1970 KILL command. Affected file lib/silcclient/command.c.
1972 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1973 case all found clients are already disconnected (WHOWAS would
1974 found them) in the server. Affected file silcd/command.c.
1976 * Update the last_receive (time of last data received) to be
1977 updated only when received private or channel message so that
1978 the idle time showed in WHOIS makes more sense.
1980 * Added boolean field `valid' in to the SilcClientEntry in the
1981 client library to indicate whether the entry is valid or not.
1982 This fixes the nickname change bug on channel when changing
1983 the nickname to be same than the old (like nick to Nick) the
1984 nickname formatter doesn't set the new nick anymore to Nick@host.
1985 Affected file lib/silcclient/idlist.[ch].
1987 * Now actually fixed the nickname changing on disconnection.
1988 Added new function silc_change_nick to the Irssi SILC Client.
1989 Affected file irssi/src/silc/core/client_ops.c,
1990 irssi/src/silc/core/silc-nicklist.[ch].
1992 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1994 * Check that the public key exists in the GETKEY command before
1995 trying to encode it. Affected file silcd/command.c.
1997 * Print some notifications on received public keys with GETKEY
1998 command in the Irssi SILC Client. Affected files are
1999 irssi/src/fe-common/silc/module-formats.[ch],
2000 irssi/src/silc/core/client_ops.c.
2002 * Use IDENTIFY command to resolve the server information in the
2003 GETKEY command instead of INFO command. Affected file
2004 lib/silcclient/command.c.
2006 * All command reply functions in the client library now calls
2007 the pending command reply callbacks even if an error has
2008 occurred. The server has done this a long time and now it was
2009 time to move the client library to this as well. Now all
2010 errors can be delivered back to the pending command reply
2011 callbacks if necessary. Affected files are
2012 lib/silcclient/command[_reply].[ch].
2014 * Change the nickname on disconnection back to the username
2015 because in reconnect the server will enforce it to it anyway.
2016 Affected file irssi/src/silc/core/silc-servers.c.
2018 * Fixed a config file parsing bug in the Irssi SILC client.
2019 Affected file irssi/src/silc/core/clientconfig.c.
2021 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * When printing the channel mode on JOIN, verify that the
2024 channel key and channel's HMAC are valid. Affected file
2025 irssi/src/silc/core/client_ops.c.
2027 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2030 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2031 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2033 * Removed channel key rekey task deleting from the function
2034 silc_server_save_channel_key. Affected file silcd/server.c.
2035 Added explicit timeout task context instead that is used to
2036 delete the task if we are registering a new task before the
2037 new task has elapsed.
2039 * When channel key rekey occurs the client library now saves
2040 the old channel key for a short period of time (10 seconds) and
2041 is able to use it in case some is still sending channel
2042 messages encrypted with the old key after the rekey. Affected
2043 file lib/silcclient/[idlist.h|client_channel.c].
2045 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Added check to the silc_server_new_id_real to not accept
2048 new ID if it is the sender's own ID. Affected file is
2049 silcd/packet_receive.c.
2051 * Assure that we do not announce ourself or the one we've
2052 sending our announcements when we're router and are announcing
2053 servers to our primary router. Affected file silcd/server.c.
2055 * Fixed silc_server_command_identify_check_client to assemble
2056 correct WHOIS packet. It send corrupted WHOIS packet and
2057 caused problem with router to router connections. Affected
2058 file silcd/command.c.
2060 Fixed also silc_server_command_whois_check the same way
2061 as for the IDENTIFY command.
2063 * Added new SilcIDListStatus to the server in the SilcIDListData
2064 structure. The status now includes the current status of
2065 the entry (like registered, resolved etc.). Affected file
2066 silcd/idlist.[ch]. Defined a bunch of different status types
2067 as well. This replaced the old boolean registered field as well.
2069 Added resolve_cmd_ident field to the SilcClientEntry structure
2070 too so that if the entry is for example being resolved so
2071 another command may attach to the same pending command reply
2072 without requiring to resolve the same entry again. This concept
2073 should optimize the WHOIS and the IDENTIFY resolving under
2074 heavy load by taking away unnecessary resolving for entries
2075 that are being resolved already.
2077 Added support for adding multiple pending commands for one
2078 command idenfier. Affected file silcd/command[_reply].[ch].
2080 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2081 before deleting the data. Otherwise the hash table will have
2082 freed data in comparison functions. Affected file is
2083 silcd/command_reply.c.
2085 * Fixed silc_idlist_replace_client_id to add the new entry to
2086 the cache with NULL nickname. Otherwise there will be invalid
2087 memory as the nickname after the nickname is freed. Affected
2088 file silcd/packet_receive.c.
2090 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2091 saved into wrong slots because the previous number of entries
2092 was not taken into account. Affected file silcd/idlist.c.
2093 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2095 * If we are router and we receive JOIN notify to a channel that
2096 does not have any users then notified client is marked as the
2097 channel founder, as it is it. The affected file is
2098 silcd/packet_receive.c
2100 * Added to the extended hash table API's table_del_*ext functions
2101 the destructor as argument too, so that the caller can decide
2102 which destructor to use or whether to use destructor at all.
2103 Affected file lib/silcutil/silchashtable.[ch].
2105 * Fixed ID Cache purging. It actually deleted the entries from
2106 the hash table after the data was freed. The hash table ended
2107 up comparing freed memory. The affected file is
2108 lib/silccore/silcidcache.c.
2110 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Fixed Irssi SILC client's KILL command's HELP syntax.
2114 * The USERS command now resolves the detailed user information
2115 if the userinfo field is missing. Affected file is
2116 lib/silcclient/command_reply.c.
2118 * Do not print error in silc_file_read if the read file does
2119 not exist. Just silently return NULL. Affected file is
2120 lib/silcutil/silcutil.c.
2122 * Fixed the silc_log_output to not wine about NULL filename
2123 and to not create some bogus " " filename. Affected file is
2124 lib/silcutil/silclog.c.
2126 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2128 * Fixed various printing bugs on the user interface in the
2129 Irssi SILC Client. Minor changes that were forgotten from
2132 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Fixed the configure.in.pre and the compilation and distribution
2135 environment to support the new autoconf 2.52. That version is
2136 now required to compile the CVS trunk.
2138 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2141 to generally parse user@fqdn format strings. Affected file
2142 lib/silcutil/silcutil.c.
2144 * Added nickname_format and nickname_force_format fields to the
2145 SilcClientParams structure. The first one defines the format
2146 for the nicknames that the library will enforce if the receives
2147 multiple same nicknames. The second one is boolean value and
2148 can be used to force the library to always enforce the format
2149 to the nicknames regardles whether there are multiple nicknames
2150 or not. This configurable formatting was employed to flexibly
2151 support accessing multiple nicknames from the user interface.
2152 The userinterface can now set the nicknames to what ever format
2153 they prefer. Affected file lib/silcclient/silcapi.h.
2155 Added function silc_client_nickname_format to the file
2156 lib/silcclient/idlist.c. It performs the nickname formatting.
2158 Added new field `hostname´ to the SilcClientEntry context.
2159 It holds the hostname of the client. Affected file is
2160 lib/silcclient/idlist.h.
2162 * Irssi SILC Client sets the nicknames in nick@hostn format.
2163 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2164 irssi/src/silc/core/silc-core.c.
2166 The WHOIS printing now also shows both the real nickname and
2167 the formatted nickname so that user knows how to access the
2168 user if there are multiple same nicknames cached. Affected
2169 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2170 printing formatting too to take the hostname now as a separate
2171 argument. The Affected file is
2172 irssi/src/fe-common/silc/modules-formats.[ch].
2174 * Changed the silc_client_get_clients_local to accept the formatted
2175 nickname as argument. It accepts the real nickname too but the
2176 formatted nickname can be used to find the true entry from
2177 multiple entries. Affected file lib/silcclient/silcapi.h and
2178 lib/silcclient/idlist.c.
2180 * Added nickname_format_parse field to the SilcClientParams.
2181 It is a callback function provided by the application to parse
2182 the nickname out of the formatted nickname string. The library
2183 calls it to get the nickname from the formatted string. Since
2184 the application generally knows better the format of the nickname
2185 string it parses it instead of the library, even though library
2186 encodes the formatted string. If the callback function is not
2187 provided then the library will use the string as is. The
2188 affected file is lib/silcclient/silcapi.h.
2190 * All the nickname strings passed to the client library in
2191 commands are now expected to be formatted nickname strings.
2192 If the command does not support the formatted nickname string
2193 it will assume that the sent string is the actual nickname.
2194 Affected file lib/silcclient/command.c.
2196 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Added public key authentication support to OPER and SILCOPER
2199 commands in the client library. Affected file is
2200 lib/silcclient/command.c.
2202 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Changed the get_auth_methdod client operation to be asynchronous.
2205 It can be async if the application resolves the authentication
2206 method from the server during the negotiation. Added new
2207 SilcGetAuthMeth completion callback that the application will
2208 call after resolving the authentication method.
2210 Added function silc_client_request_authentication_method that
2211 the application can use to resolve the authentication method
2212 from the server. Added also SilcConnectionAuthRequest callback
2213 that the library will call after the server has replied. The
2214 application can call this function if it does not know the
2215 current authentication method.
2217 Affected files are lib/silcclient/client.c and
2218 lib/silcclient/silcapi.h.
2220 * The Irssi SILC client now automatically resolves the authentication
2221 method incase any configuration information is not present (and
2222 currently there never is). The affected file is
2223 irssi/src/silc/core/client_ops.c.
2225 * Fixed public key authentication from the client library.
2226 Affected file lib/silcclient/protocol.c. Changed also the
2227 protocol specification about the public key authentication in
2228 the connection authentication protocol. The actual data to be
2229 signed is now computed with a hash function before signing.
2231 * Fixed the public key authentication from the server as well.
2232 Affected file silcd/protocol.c.
2234 * Removed the mlock()'s from the memory allocation routines.
2235 Affected file lib/silcutil/silcmemory.c. The ./configure does
2236 not check anymore for the mlock(). Affected file is
2239 * Fixed USERS command in server to allow the execution of the
2240 command for private and secret channels if the client sending
2241 the command is on the channel. Affected file silcd/command.c.
2243 * Fixed silc_client_get_clients_local to return the clients
2244 count correctly. It could return wrong value. Affected file
2245 lib/silcclient/idlist.c.
2247 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2249 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2250 types. The assembler optimizations seemed not to like 64-bit
2251 data types. The assmebler optimizations thus are now enabled
2252 also for BSD systems as opposed to only enable them for Linux.
2254 * Do not check for threads at all on BSD systems. Affected
2255 file configure.in.pre.
2257 * Removed -n and -h options from the Irssi SILC Client since
2258 they are not used in silc.
2260 * Fixed the prime generation to assure that the first digit
2261 of the generated random number is not zero since our conversion
2262 routines does not like number strings that starts with zero
2263 digit. If zero digit is seen the random number is regenerated.
2264 This caused some corrupted RSA keys when the zero first digit
2265 was met. Affected file lib/silcmath/silcprimegen.c.
2267 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Fixed WIN32 configuration in the ./configure script.
2270 Fixed to include xti.h on environments that has it.
2271 Patches by Carsten Ilchmann and andrew.
2273 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2275 * Changed the silc_id_create_client_id to be collision
2276 resistant. It is now assured that there cannot be created
2277 two same client ID's. I suspect that some weird bugs in
2278 the server were actually caused by duplicate Client IDs.
2279 Affected file silcd/serverid.[ch]. A router receiving
2280 new ID now also assures and informs the sending server
2281 if the ID caused collision.
2283 * Changed the silc_id_create_channel_id to also assure that
2284 there are no collisions.
2286 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Statement about ignoring the Mutual Authentication flag when
2289 performing rekey with PFS was a bit misleading. It is ignored
2290 if it was set in the initial negotiation, it cannot be even
2291 set in the rekey. Fixed in the ke-auth draft. Started the
2292 new versions of the protocol drafts in the doc/.
2294 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Fixed a bug in silc_client_command_identify_save when saving
2297 new channel information. The channel name was no duplicated
2298 and caused crash on exit. Affected file is
2299 lib/silcclient/command_reply.c.
2301 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Fixed the getkey command handling in the server. Send just
2304 empty OK reply to the sender if the key could not be fetched
2305 (but everything else was ok, like the key just was not available).
2306 Changed the public key parameter to optional in the protocol
2307 specs so that empty OK reply can be sent. Affected file
2310 Added a message to Irssi SILC client to tell to user if the
2311 server did not return a public key.
2313 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Fixed a channel key regeneration bug. It registered new
2316 timeout tasks exponentially until all system resources were
2317 used. Affected file silcd/server.c.
2319 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Added the SILC Document generator to the scripts/silcdoc.
2322 It can be used to generate the Toolkit Reference Manual out
2323 of the source tree. Internally it will also use the RoboDoc
2324 generator now imported in util/robodoc.
2326 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Added couple of return's in rekey protocol if error orccurred
2329 during the protocol. The execution must be terminated.
2330 Affected file silcd/protocol.c. Also, terminate the protocol
2331 always with timeout.
2333 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * The client's Client ID was created initally from the wrong
2336 nickname (it could have been in format nick@host) in the
2337 silc_server_new_client. Affected file silcd/packet_receive.c
2339 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Added some SILC_LOG_ERROR's to various error conditions
2342 if client could not be added to ID cache. Affected files
2343 silcd/packet_receive.c and silcd/server.c.
2345 * When client's sock->user_data is freed, NULL also the
2346 client->router and client->connection pointers. Added check
2347 for these pointers being NULL to various places around the
2348 code. Affected file silcd/server.c.
2350 * Added client->data.registered == TRUE checks to various
2351 places around the code to assure that unregistered client's
2352 are not handled when it is not allowed. Affected file
2355 * Added `bool registered' fields to all
2356 silc_idlist_[server|client]_get_* routines to indicate whether
2357 the fetched client needs to be registered or not. Affected
2358 file silcd/idlist.[ch].
2360 * Add your own entry as registered to the ID cache in the
2361 server. Affected file server.c.
2363 * Fixed a bug in silc_server_new_server. The SilcServer was
2364 set as the new server's context instead of SilcServerEntry.
2365 This naturally caused some weird bugs.
2367 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Do not delete the channel rekey task when adding it
2370 for in silc_server_create_channel_key.
2372 * Changed the silc_server_create_channel_key to return
2373 TRUE or FALSE to indicate the success of the channel key
2376 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Fixed MSVC++ project files and added missing files to
2379 Makefiles under win32/.
2381 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Do not add TCP_NODELAY flag if the operating system
2384 does not have it defined. Affected files are
2385 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2387 * Fixed buffer overflow from Irssi SILC Client. Affected
2388 file irssi/src/fe-common/core/themes.c.
2390 * Fixed double free in client library in the file
2391 lib/silcclient/client.c when disconnecting from server.
2393 * Applied double free patch from cras to Irssi SILC client.
2394 Affected files irssi/src/core/[modules/expandos].c
2396 * Fixed the disconnection handling to Irssi SILC Client.
2397 The application must call silc_client_close_connection
2398 in ops->connect client operation in case of failure of
2399 the connection. Affected file is
2400 irssi/src/silc/core/client_ops.c.
2402 * Do not set sock->protocol to NULL in the function
2403 silc_client_close_connection after executing the protocol's
2404 final callback since the sock might not be valid anymore.
2405 Affected file lib/silcclient/client.c.
2407 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Do not enable SILC_THREADS if the linking with libpthread
2410 did not happen. Affected file configure.in.pre.
2412 * Added notion to protocol specification that server must
2413 verify the sent authentication payload with CMODE when
2414 setting the channel founder key. Implemented it to the
2415 server. Affected file silcd/command.c.
2417 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Added _EXTRA_DIST SILC distribution variable to the
2420 distributions file. It is used to conditionally add extra
2421 files or directories to the specific distribution. Affected
2422 files ./prepare, Makefile.am.pre and distributions.
2424 Removed the `_' from the start of the distribution names.
2427 * Added README.WIN32 for instructions to compile the Toolkit
2430 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Fixed a double free in disconnection in the server. Affected
2433 file is silcd/server.c.
2435 * Fixed the lib/silcske/groups.c to work now also with GMP
2436 MP library. The string conversion did not work when using
2437 specific base and the base is indicated in the string as well.
2439 * Created win32/ directory which now includes MSVC++ specific
2440 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2441 It will appear only in the toolkit distribution
2443 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Changed the key material distribution function in case when
2446 the hash output is too short. The data is now concatenated
2447 a bit differently than it used to. Made the change to the
2448 SKE protocol specification.
2450 * Added better GMP detection to configure.in.pre. A patch
2453 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Fixed a minor bug in SKE that might cause some problem on
2456 some platforms. Affected file lib/silcske/silcske.c.
2458 * Added the cookie checking for initiator in the SKE. It checks
2459 that the responder returns the sent cookie unmodified. The
2460 affected file is lib/silcske/silcske.c. Added new SKE
2461 error type INVALID_COOKIE that can be sent during the
2462 negotiation. Fixed some memory leaks as well.
2464 * Added the "invalid cookie" error message to Irssi SILC client's
2467 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Added `task_max' field to the SilcClientParams to indicate
2470 the maximum tasks the scheduler can handle. If set to zero,
2471 default values are used. Affected file lib/silcclient/silcapi.h.
2473 * Fixed memory leaks in silc_client_close_connection. Affected
2474 file lib/silcclient/client.c.
2476 * Added silc_client_del_client_entry to client library to free
2477 all memory of given client entry. Affected file is
2478 lib/silcclient/idlist.[ch].
2480 * Added new functions silc_client_del_channel and
2481 silc_client_del_server to delete channel and server entries.
2482 Affected file lib/silcclient/[silcapi.h/idlist.c].
2484 * Removed silc_client_del_client_by_id from silcapi.h.
2486 * Fixed the INFO command to return the server's own info
2487 correctly when querying by Server ID. Affected file is
2490 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Removed the non-blocking settings in WIN32 code in the
2493 silc_sock_[read/write] and added SleepEx instead. Affected
2494 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2495 of input data is now checked with FIONREAD and ioctlsocket.
2497 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Call silc_schedule_task_del_by_context in the
2500 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2501 Affected file lib/silccore/silcprotocol.c.
2503 * Call silc_protocol_cancel for active protocols in the
2504 silc_server_close_connection if the funtion
2505 silc_server_free_sock_user_data has not been called.
2506 Affected file silcd/server.c.
2508 * Generic tasks cannot be deleted using the del_by_fd
2509 task deleting function since generic tasks does not match
2510 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2512 * Added a notion to SILCOPER help file that the SILCOPER works
2513 only on router server, not on normal server.
2515 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Added for WIN32 support for the new scheduler as well.
2518 Affected file lib/silcutil/win32/silcwin32schedule.c.
2520 * Fixed the SHA1 implementation to work on various platforms.
2522 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2524 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2525 API. It is part of the scheduler now. Everything else is
2526 as previously but some functions has changed their names.
2527 Checkout the lib/silcutil/silcschedule.h for the interface.
2528 Updated all applications to use the new interface. Affected
2529 files are lib/silcutil/silcschedule.[ch].
2531 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Found a bug in the SKE implementation. The HASH value,
2534 specified by the protocol, was not computed correctly. The
2535 public key of the responder was not added to the computation
2536 even though it is mandatory. Affected file lib/silcske/silcske.c.
2537 This unfortunately causes incompatibilities with older
2538 clients and servers.
2540 * Added WIN32 specific network init and uninit functions:
2541 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2542 the Winsock2. Affected file lib/silcutil/silcnet.h and
2543 lib/silcutil/win32/silcwin32net.c.
2545 * Set the socket always to nonblocking mode on WIN32 after
2546 reading data or writing data. Affected file is
2547 lib/silcutil/win32/silcwin32sockconn.c.
2549 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Fixed various compilation problems under WIN32. Affected
2552 files lib/silcutil/win32/silcwin32thread.c and
2553 lib/silcutil/win32/silcwin32schedule.c.
2555 * Removed all _internal.h #includes from public header
2556 files. Internal headers must never be included from
2559 Removed also the lib/silcske/payload_internal.h file.
2561 * All include files that may be needed (public and some others
2562 included by the public headers) by application developers are
2563 now copied to the ./includes directory. It does not copy any
2564 internal headers. Affected file Makefile.defines.pre and all
2565 Makefile.am's under lib/ and subdirs.
2567 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Do not change the ~/.silc directory's permissions automatically.
2570 Affected file irssi/src/silc/core/clientutil.c.
2572 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Do not cancel the protocol in silc_server_close_connection
2575 it might cause recursion. Now cancelled in the function
2576 silc_server_free_sock_user_data. Affected file silcd/server.c.
2578 * Fixed the silc_server_remove_clients_by_server to regenerate
2579 the channel keys correctly finally. Added also new function
2580 silc_server_remove_clients_channels to actually do it.
2581 Affected file silcd/server.c.
2583 * Fixed the silc_server_new_channel to not crash by giving
2584 wrong router to the new channel. Affected file is
2585 silcd/packet_receive.c.
2587 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2590 which is given as argument to the silc_client_alloc now.
2591 It can be used to configure the client and set various parameters
2592 that affect the function of the client.
2594 * The USERS command in server did not check whether the channel
2595 is private or secret. Affected file silcd/command.c.
2597 * Added new argument to the USERS command in protocol specification.
2598 The USERS command now can take the channel name as argument
2599 as well. Added support for this in client and server and
2600 updated the protocol specs.
2602 * Completed the GETKEY command in client. It can be now used
2603 to fetch also servers public key not only some clients.
2604 Affected files lib/silcclient/command[_reply].c.
2606 * Added silc_client_get_server to return server entry by the
2607 server name. Affected files lib/silcclient/silcapi.h and
2610 * Redefined the IDENTIFY command in protocol specification to be
2611 more generic. It now can be used to query information about
2612 any entity in the SILC Network, including clients, servers and
2613 channels. The query may be based either the entity's name
2614 or the ID. Added support for this in both client and server.
2616 Affected files silcd/command.c and lib/silcclient/command.c
2617 and command_reply.c.
2619 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2620 the _from_client and _from_server functions. Affected file
2623 * Added silc_client_get_channel_by_id_resolve to the file
2624 lib/silcclient/silcapi.h to resolve channel information by
2625 its ID. Added also silc_client_get_channel_by_id that
2626 does not resolve it from the server.
2628 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * Added SilcServerEntry context into the client library
2631 to represent one server. The INFO command now allocates
2632 these to save the resolved server info. For now on the
2633 client library will also keep information about servers,
2634 connected and resolved with INFO.
2636 The INFO command now allocates the SilcServerEntry context
2637 and saves the server info there. The COMMAND_REPLY in
2638 the INFO now returns the parameters to application in
2639 same order as defined in the protocol specification.
2641 The entries are cached in the client->server_cache.
2643 * The INFO command is now issued after received the Client ID
2644 from the server. Affected file lib/silcclient/client.c.
2646 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2647 to the application as the mode changer might be server.
2648 It is guaranteed that NULL is not returned anymore to the
2649 application. Affected file lib/silcclient/client_notify.c.
2651 The ID Type is now also passed to the application so that
2652 it can check whether the returned entry is SilcClientEntry
2655 Added new function silc_client_get_server_by_id to return
2656 the server entry by ID. Affected files are the
2657 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2659 * Do not create the channel in the Irssi SILC Client when issuing
2660 the JOIN command but when received the sucessful JOIN command
2661 reply. Otherwise the channel might get created even though we
2662 could not join it. The Affected file is
2663 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2665 * Fixed a channel joining bug in router. The router must also
2666 check the channel modes, invite and ban lists etc. when serving
2667 the JOIN command sent by normal server. Affected file is
2668 silcd/command.c. The router now resolves the client's
2669 information from the server who sent the JOIN command if it
2670 does not know it, and processes the JOIN command only after
2673 * Changed the SilcCommandCb to take new argument; void *context2.
2674 Affected file lib/silccore/silccommand.h
2676 The second argument in the command callbacks in the server now
2677 includes the SilcServerCommandReplyContext if the command was
2678 called as pending command callback from the command reply.
2679 Otherwise it is NULL. When called as pending the status of the
2680 command reply will be checked and if it was erronous the
2681 error will be sent to the original sender of the command.
2682 This way the client always receives the error messages even
2683 though the server was actually the one who received the error
2684 when it resent the command to router, for example. Affected
2685 files silcd/command[_reply].[ch].
2687 * Fixed sending WHOWAS command's error message to client if
2688 the requested client could not be found. It was missing.
2691 * Changed the CMODE and CUMODE commands reply arguments in the
2692 protocol specification. The Channel ID is now sent in both
2693 of the commands to identify the channel. Implemented this
2694 new feature to the client and server. Affected files
2695 lib/silcclient/command_reply.c and silcd/command.c.
2697 * Made better checks for invite and ban lists in the JOIN
2698 command in server. Affected file silcd/command.c.
2700 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * The server now performs the incoming host IP/DNS lookup
2703 using the silc_socket_host_lookup and thus does not block
2704 the server anymore. Affected file silcd/server.c.
2706 * Completed the multi-thread support for SILC Scheduler in
2707 the lib/silcutil/silcschedule.c.
2709 * Fixed the configure.in.pre to detect the pthread correctly
2712 * Fixed a deadlock in silc_task_queue_wakeup in the file
2713 lib/silcutil/silctask.c.
2715 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Added new function silc_schedule_wakeup that is used in
2718 multi-threaded environment to wakeup the main thread's
2719 schduler. It needs to be used when a thread adds a new task
2720 or removes a task from task queues. After waking up, the
2721 scheduler will detect the task queue changes. If threads
2722 support is not compiled in this function has no effect.
2723 Implemented the wakeup mechanism to both Unix and WIN32
2724 systems. Affected files are lib/silcutil/silcschedule.[ch],
2725 lib/silcutil/unix/silcunixschedule.c and the
2726 lib/silcutil/win32/silcwin32schedule.c.
2728 * Added new function silc_task_queue_wakeup to wakeup the
2729 scheduler by the specified task queue. Affected file
2730 lib/silcutil/silctask.[ch].
2732 * The silc_socket_host_lookup_start now wakes up the scheduler
2733 after adding the timeout task. Affected file is
2734 lib/silcutil/silcsockconn.c.
2736 * The silc_socket_host_lookup is synchronous now if the threads
2737 support is not compiled in. However, the callback is still
2738 called asyncronously through the scheduler, anyway. Affected
2739 file lib/silcutil/silcsockconn.c.
2741 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Added new function silc_socket_host_lookup to perform
2744 asynchronous IP and FQDN lookups for the socket connection.
2745 Affected files lib/silcutil/silcsockconn.[ch].
2747 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2749 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2750 that may or may not compile the mutex support in.
2752 Changed the silc_mutex_alloc interface. It allocates the
2753 mutex now to the sent pointer and returns TRUE or FALSE.
2755 Affected file lib/silcutil/silcmutex.h.
2757 * Wrote the SILC Task Queue interface to support multi-threads.
2758 Affected file lib/silcutil/silctask.[ch].
2760 * Wrote the SILC Scheduler to support multi-threads. Affected
2761 file lib/silcutil/silcschedule.c.
2763 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2766 in lib/silcutil/win32/.
2768 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Defined SILC Mutex API and SILC Thread API and implemented
2771 them for Unix. Affected files are
2772 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2773 lib/silcutil/unix/silcunixmutex.c and
2774 lib/silcutil/unix/silcunixthread.c.
2776 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Fixed the silc_server_remove_clients_by_server's channel
2779 key re-generation. The hash table handling was incorrect
2780 and would not work with many channels. Affected file is
2783 * Fixed some memory leaks around the server code.
2785 * Rewrote the silc_server_get_users_on_channel to support IPv6
2786 based Client ID's. Affected file silcd/server.c.
2788 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2789 specification. However, a separate document must be written
2790 to define the detailed signing procedure and the payload
2791 associated with the flag. Defined the flag to the
2792 lib/silccore/silcchannel.h as well.
2794 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2796 * Changed the dynamic tables to static size tables in the
2797 lib/silccrypt/silchmac.c.
2799 * Removed GCC dependencies from the code. A patch by cras.
2801 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Do not show the error "Error receiving packet bla bla"
2804 in server if it really was not an error (-2 means that reading
2805 is pending). Affected file silcd/server.c.
2807 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Fixed a possible crash in silc_server_remove_clients_by_server
2810 in silcd/server.c. Fixed there also some memory leaks.
2812 * Fixed the silc_idlist_replace_client_id. It could replace
2813 wrong key in the hash table. Affected file silcd/idlist.c.
2815 * Do not check whether there are global users on the channel
2816 if the channel->global_users is FALSE. Affected functions
2817 silc_server_remove_from_one_channel and
2818 silc_server_remove_from_channels in silcd/server.c. Also,
2819 do not check if the removed client is local as we can be
2820 sure that global client was not removed from the channel
2821 and checking for global users is not needed.
2823 * The silc_server_remove_clients_by_server now re-generates
2824 the channel keys correctly for those channels that had
2825 clients removed from them. Affected file silcd/server.c.
2827 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Found the reason of random crashes in the server. We weren't
2830 ignoring the SIGPIPE signal (which can be sent in write())
2831 and it crashed the server. Affected file silcd/silcd.c.
2833 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Assure that sock->user_data is not NULL in the function
2836 silc_server_packet_send in silcd/packet_send.c.
2838 * Disconnect the remote connection if it could not be added
2839 to any ID lists in the server. The affected file is
2842 * Check in silc_server_packet_send[_real/dest] that the
2843 socket is not disconnecting and ignore the data if it is.
2844 Affected file silcd/packet_send.c.
2846 * Define inline to __inline on native WIN32 compilation.
2847 Affected file includes/silcwin32.h.
2849 * Added some explicit type casts for inline code since MSVC
2850 require them. Affected files lib/silcutil/silcbuffer.h,
2851 lib/trq/silcdlist.h and lib/trq/silclist.h.
2853 * Print warning in log files from now on if the packet
2854 decryption fails. Affected file silcd/server.c.
2856 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Changed the `say' client operation's interface to accept
2859 new `type' argument to indicate the type of the message sent
2860 by the library. The application may filter the library's
2861 messages according the type. The affected file is the
2862 lib/silcclient/silcapi.h.
2864 * Added two new functions to lib/silcclient/silcapi.h:
2865 silc_client_del_client and silc_client_del_client_by_id.
2866 Affected file lib/silcclient/idlist.c.
2868 * Moved the clientincludes.h from includes/ to silc/ and
2869 serverincludes.h from includes/ to silcd/.
2871 * The modes for the CMODE and CUMODE are now passed as
2872 uint32 for application with COMMAND_REPLY. The affected
2873 file is lib/silcclient/command_reply.c.
2875 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * /WHOIS without arguments shows client's own information.
2878 Affected file lib/silcclient/command.c.
2880 * Changed PING to not accept any arguments. The specs
2881 says that client can ping only the connected server so
2882 requiring an argument is not needed. Affected file is
2883 lib/silcclient/command.c.
2885 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Fixed a fatal bug in private message sending and reception
2888 encryption and decryption when using private message keys.
2889 The implementation was incorrect and did not follow the
2890 specification. It causd that some of the message were
2891 lost since it did not use the sending and receiving keys
2892 as the protocol suggests. This has been fixed and will cause
2893 incompatibilities with older clients when sending private
2894 message encrypted with private message keys. Affected files
2895 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2896 and various other in Irssi SILC Client.
2898 Added `responder' boolean argument to the functions
2899 silc_client_add_private_message_key[_ske] to indicate when
2900 the key is added as responder or initiator of the key
2903 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Removed the silc_ske_check_version function and created
2906 a SilcSKECheckVersion callback. Added also a function
2907 silc_ske_set_callbacks that is now used to set all SKE
2908 callbacks. The callback functions are not given to
2909 the SKE functions anymore, but this function is used to
2912 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2914 * Added `silc_version' argument to the silc_client_alloc
2915 to define the version of the application for the library.
2916 The library will use the version string to compare it
2917 against the remote host's (usually a server) version
2918 string. Affected file lib/silcclient/silcapi.h
2920 * Added the KE protocol context to Key Agreement context
2921 in client library so that we can abort the SKE if it
2922 is in process when we get timeout. Affected file is
2923 lib/silcclient/client_keyagr.c.
2925 * Do not resolve the client ID forever if it returns in the
2926 first time that such client does not exist. This was done
2927 for example with private message. Affected file is
2928 lib/silcclient/client_prvmsg.c.
2930 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2932 * Do not add regex.h for WIN32. The affected file
2933 includes/silcincludes.h.
2935 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2936 not work yet 100%. It generates the DLL's automatically
2937 when compiling with --with-win32 under cygwin.
2939 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * lib/contrib/regex.c is not compiled on WIN32.
2943 * Added silc_net_get_socket_opt function to the
2944 lib/silcutil/silcnet.h.
2946 * Added includes/silcwin32.h for WIN32 specific includes
2949 * Do not use ptime structure or any of the posix process
2950 functions on WIN32 in lib/silccrypt/silrng.c.
2952 * Added silc_gettimeofday to provide generic function
2953 for struct timeval on all platforms. Added the function
2954 to lib/silcutil/silcutil.h.
2956 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2959 library as they clearly belong there. As a plus side we
2960 can make the actual socket connection routines platform
2963 Added also new generic function silc_socket_read and
2964 silc_socket_write (that used to be silc_packet_[read/write].
2965 The implementation of these are platform specific.
2967 * Added WIN32 specific routines of silc_socket_[read/write]
2968 to lib/silcutil/win32/silcwin32sockconn.c.
2970 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Added preliminary support for native WIN32 compilation under
2973 cygwin (using the -mno-cygwin option for GCC) to the
2974 ./configure.in.pre. The --with-win32 now prepares the
2975 compilation for native WIN32.
2977 * Rewrote the SILC Scheduler interface in the file
2978 lib/silcutil/silcschedule.h. The scheduler is now context
2979 based and does not have anymore any global static scheduler.
2980 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2981 and created lib/silcutil/win32 directory for WIN32 based
2984 * Added Unix specific network routines to the
2985 lib/silcutil/unix/silcunixnet.c and the old
2986 lib/silcutil/silcnet.c includes now only generic routines.
2988 Added WIN32 specific network routines to the
2989 lib/silcutil/win32/silcwin32net.c.
2991 * Added Unix specific utility functions from the
2992 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2994 * Added WIN32 SILC Scheduler to the file
2995 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2998 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Do not handle JOIN notify in the server if the target client
3001 is not registered (idata->registered == FALSE). The affected
3002 file is silcd/packet_receive.c.
3004 * Update the nickrec->founder in event_cumode in the Irssi SILC
3005 client. Affected file irssi/src/silc/core/silc-channels.c.
3007 * Fixed the CUMODE_CHANGE notify handling in the server when
3008 server and router are announcing their clients on channels.
3009 Now the mode changes are saved and notified correctly. The
3010 affected file is /silcd/packet_receive.c.
3012 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3013 They really did not replace the cache entry in the ID Cache.
3014 Now they do that. Affected file silcd/idlist.c.
3016 * Fixed the KICK notify handling in the Irssi SILC client to
3017 update the channel records so that the kicked client does not
3018 appear to be on the channel. The affected file is
3019 irssi/src/silc/core/silc-channels.c.
3021 * Always update the conn->current_channel when executing command
3022 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3024 * Fixed the KILL notify handling in Irssi SILC client to remove
3025 the killed client on all channels.
3027 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Fixed the silc_parse_command_line to remove extra spaces
3030 from the start and end of the arguments. Affected file is
3031 lib/silcutil/silcutil.c.
3033 * Cancel and free any active protocol in the function
3034 silc_server_close_connection. Affected file silcd/server.c.
3036 * Cancel and free any active protocol in the function
3037 silc_client_close_connction. Affected file is
3038 lib/silcclient/client.c.
3040 * Do not execute the KILL command for clients that are in
3041 history (ie. they are not in the network). Affected file is
3044 * Fixed KILL notify handling, client does not crash anymore.
3045 Affected file irssi/src/silc/core/silc-channels.c.
3047 * Reduced the default packet buffer size from 2048 to 1024 in
3048 lib/silccore/silcpacket.c.
3050 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3051 counter to the SKE context that is incresed when the SKE library
3052 performs async operation outside the library. If the outside
3053 process frees the SKE context and FREED status will be set
3054 and the library will detect after the sync operation that the
3055 libary is freed. The affected files are
3056 lib/silcske/silcske[_status].[ch].
3058 * Resolve the client entry information in the function
3059 silc_client_channel_message to assure that NULL pointer is not
3060 passed as client entry to the application. */
3062 * Fixed the task timeout calculation to assure that there is
3063 never negative timeouts. The affected file is
3064 lib/silcutil/silcschedule.c.
3066 * Fixed the channel user mode notification sending in server.
3067 It was sent point-to-point to the router (or to server by router)
3068 but it needs to be destined to a channel. The routines now
3069 supports sending the channel user mode notifys to the channels
3070 when announcing clients and channels. Affected files are
3071 silcd/server.c and silcd/packet_receive.c.
3073 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3074 It did not actually replace the old channel entry in the cache.
3075 Affected file lib/silcclient/client_notify.c.
3077 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Fixed a possible crash in silc_packet_send_prepare. It now
3080 assures always that there is enough space in the buffer and
3081 at the tail area of the buffer (for MAC).
3083 Fixed the inbound buffer reallocation in silc_packet_read.
3084 It was old code and did not handle the reallocation correctly.
3087 The affected file is lib/silccore/silcpacket.c.
3089 * Fixed buffer overflow in silc_parse_nickname in the file
3090 lib/silcutil/silcutil.c.
3092 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * make install generates new server keys only if there is not
3097 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3099 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3100 Added check that if the NOREPLY is set then we will not send
3101 the away message. This avoids infinite loop of away messages
3102 if both clients are away. The affected file is
3103 lib/silcclient/client_prvmsg.c.
3105 * Fixed client crash if /NICK was given without arguments.
3106 Affected file lib/silcclient/command.c.
3108 * Server does not send the invite list in INVITE command back
3109 to the client if the list was not altered. Added this notion
3110 to the protocol spec as well. Affected file silcd/command.c.
3112 Fixed possible crash in INVITE command by checking the
3113 value of silc_server_get_client_route command.
3115 * Fixed the INVITE notify type handling. The arguments are now
3116 taken in correct order and client does not crash. The affected
3117 file is irssi/src/silc/core/silc-channels.c.
3119 Removed the "Inviting xxx to channel" message from the
3120 client library away and let the application handle it.
3121 Affected file lib/silcclient/command.c. Added that message
3122 to Irssi SILC client's message formats.
3124 * Fixed CMODE command crash in client. It now checks the
3125 amount of arguments correctly and does not crash. The affected
3126 file is lib/silcclient/command.c.
3128 * Do not create new channel automatically in silc_channels_join
3129 but check whether the channel by that name already exists.
3130 Affected file irssi/silc/core/silc-channels.c.
3132 * Do not send the SERVER_SIGNOFF to router if the disconnected
3133 entity was the router. Affected file silcd/server.c.
3135 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3136 SILC client as it was missing from there.
3138 Added the handling of the KICK notify to the Irssi SILC client
3139 as it was missing. Added "you have been kicked" message to
3140 Irssi SILC client's message modules formats.
3142 Added the handing of the KILL notify to the Irssi SILC client
3143 as it was missing. Added the kill message module formats
3146 The affected file is irssi/src/silc/core/silc-channels.c.
3148 * The router did not save the channel mode the server announced.
3149 Affected file silcd/packet_receive.c.
3151 * Fixed a possible crash in INFO command in server. If the
3152 server did not provide the server info it crashed. Affected
3153 file silcd/command.c.
3155 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Fixed the GETKEY command in the server to check also the
3158 global list. Otherwise the GETKEY would not work correctly
3159 in normal SILC server. Affected file silcd/command.c.
3161 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Fixed GETKEY crash, it crashed if the command did not succseed.
3165 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3168 is now real and not just an macro interface to GMP.
3170 Removed the entire GMP from the source tree and imported new
3171 NSS MPI library instead. Reason for removing GMP is that it is
3172 extremely large and compiles extremely slow. The NSS MPI
3173 is only a few files and compiles in less than 10 seconds.
3174 The speed is also about the same as GMP. The MPI is imported
3175 to lib/silcmath/mpi.
3177 If the system has GMP installed we will still use the GMP.
3178 If it is not then the NSS MPI will be compiled.
3180 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Merged a long nickname (127 characters long) crash bugfix from
3183 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3185 * Merged a freed memory reference bugfix from Irssi CVS tree.
3186 Affected file irssi/src/core/commands.c.
3188 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Added the server's public key sving and verification to the
3191 server when performing the SKE. This was missing and the
3192 remote server's (or router's) public key was accepted without
3193 checking whether we have it previously or trust it at all.
3194 Affected file silcd/protocol.c.
3196 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Check in the silc_server_timeout_remote if protocol is active
3199 and make sure that the protocol's final callback is called so
3200 that all memory if freed. Affected file silcd/server.c.
3202 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * silc_server_whois_send_reply crashed the server if the nickname
3205 was 127 characters long. Affected file silcd/command.c.
3207 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Added sanity check to the silc_server_new_client. If the hostname
3210 is provided inside username then check that the provided hostname
3211 really is the same as the resolved one. If the hostname was not
3212 resolved then check it from the public key. Affected file is
3213 silcd/packet_receive.c.
3215 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3216 if the server disconnected us and the connection is not valid
3217 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3219 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3220 the library to the lib/silcutil/silcutil.[ch].
3222 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Close log file after open. Affected file
3225 lib/silcutil/silclog.c.
3227 * Check whether sock == NULL in silc_client_send_packet and return
3228 if it is. Affected file lib/silcclient/silcclient.c.
3230 * Check rec->entry == NULL in the Irssi SILC Client before
3231 sending the channel message. Affecte file is
3232 irssi/src/silc/core/silc-servers.c.
3234 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Merged a splitted window bugfix from Irssi CVS tree. The
3237 affected file is irssi/src/fe-text/textbuffer-view.c.
3239 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3240 It did not print nickname.
3242 * Improved the distributions system a bit.
3244 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3247 irssi/src/fe-text/gui-window.c.
3249 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3250 to in-active server. The affected file is
3251 irssi/src/silc/core/client_ops.c.
3253 * Resolve the client in USERS command reply if the entry does
3254 not have username resolved. The affected file is
3255 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3256 command to WHOIS command to really resolve stuff. The USERS
3257 is not used any more in any critical section so WHOIS can
3258 be used even though it might be slower than IDENTIFY.
3260 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3263 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Changed the protocol API a bit more consistent in the
3266 lib/silccore/silcprotocol.[ch].
3268 * Changed the following headers to ROBODoc format:
3270 lib/silccore/silcpayload.h
3271 lib/silccore/silcprotocol.h
3272 lib/silccore/silcsockconn.h
3274 All core library headers are now formatted.
3276 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Fixed a bug in Irssi SILC client; do not show that you are
3279 server/router operator if you really are not. Affected file is
3280 irssi/src/silc/core/client_ops.c.
3282 * Renamed silc_command_free_payload to silc_command_payload_free.
3283 Affected file lib/silccore/silccommand.h
3285 * Added silcmath.h to include the prototoypes of various routines
3286 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3289 * Changed the following headers to ROBODoc format:
3291 lib/silccore/silcchannel.h
3292 lib/silccore/silccommand.h
3293 lib/silccore/silcid.h
3294 lib/silccore/silcidcache.h
3295 lib/silccore/silcmode.h
3296 lib/silccore/silcnotify.h
3297 lib/silccore/silcpacket.h
3298 lib/silcmath/silcmath.h
3300 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Added checking to the server code not to start the server if
3303 ciphers and stuff are not configured properly. Affected files
3304 silcd/serverconfig.[h] and silcd/server.c.
3306 * Changed the layout of the header files of the public interfaces
3307 in the SILC libraries. The new layout supports ROBODoc
3308 documentation tool (and some others) so that it is easy to create
3309 a library reference manual. All the other headers and source
3310 code must still follow the CodingStyle document. Also source
3311 code must not include these ROBODoc stuffs, only the headers.
3312 Furthermore, all public interface headers must now be named
3313 by using `silc' prefix, example: silcapi.h, silccipher.h.
3314 Some files were renamed due to this. All the other headers
3315 must not be used as public interfaces. I will update the
3316 CodingStyle document later. Changed following headers, so far:
3318 lib/silcclient/silcapi.h
3319 lib/silccore/silcauth.h
3320 lib/silccore/silcprivate.h
3321 lib/silccrypt/silcdh.h
3323 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Removed silc_client_packet_send_flush from the client library
3328 as it is not needed. Affected file lib/silcclient/client.[ch].
3330 * Added printing of message of unresolved authentication method
3331 to the Irssi SILC client. Added it to the module formats.
3332 Removed the same message from the client library.
3334 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Added new distribution feature, DISTLABEL. Every distribution
3337 can define own preprocessor label that can be used in the
3338 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3339 file distributions, acconfig.h.pre and prepare.
3341 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Added Makefile.defines_int to include the actual definitions
3344 for Makefile.defines.in. Tested the new distribution system,
3345 created distributions and tested installation.
3347 * Added AWAY message printing to the Irssi SILC client. Added
3348 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3350 * Added SCONNECT command to call the SILC's CONNECT command.
3351 Cannot use CONNECT directly since Irssi uses that internally.
3352 Affected file irssi/src/silc/core/silc-servers.c.
3354 Added ACTION local command. It is same as ME command but takes
3355 the channel as mandatory argument.
3357 Rewrote some of the Irssi's help files to suite for SILC
3360 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added Makefile.defines[.in] that should for now on be included
3363 in all Makefile.am file in the source tree. That file includes
3364 all common compilation definitions for SILC source tree.
3366 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Minor changes to the ./prepare script to change the package
3369 name according the distribution name to the configure.in.
3371 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Created new distribution system. Added file `distributions'
3374 that defines all the distributions that can be created out of
3375 the SILC source tree. The ./prepare script now reads that
3376 file to determine how to prepare the distributions. The
3377 first argument to the ./prepare is the name of the distribution
3378 and second is the version of the distribution. If given
3379 without arguments it creates the default (toolkit) distribution
3380 with the default version (defined in ./prepare).
3382 All Makefile.am files that are subject to the distributions
3383 are now named as Makefile.am.pre. These are ./Makefile.am
3384 and lib/Makefile.am. Others may be changed later.
3386 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Added invite list, ban list, some key management and connection
3389 error message printing to module formats in the Irssi SILC client.
3391 * Added new silc_client_set_away_message to set the away message
3392 that is back to the person who sent private message. The
3393 affected file lib/silcclient/silcapi.h and the
3394 lib/silcclient/client_prvmsg.c.
3396 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Fixed the private message sending in the Irssi SILC client,
3399 added local command KEY to the Irssi SILC client.
3401 Added key management and key agreement message formats to the
3402 irssi/src/fe-common/silc/module-formats.[ch].
3404 Added USERS (alias WHO) printing, server/router operator
3405 indication and LIST command printing to the module formats.
3407 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Fixed channel joining notify handling, cumode notify handling
3410 from Irssi SILC client.
3412 * Added SILC specific module-formats to the Irssi SILC client so
3413 that SILC specific message hilighting, colors etc is possible.
3414 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3416 Added channel mode, channel user mode, actions, notices,
3417 whois and whowas printing to the the module-formats.c.
3419 * Fixed a bug in channel deletion in the server. The channel
3420 is not left to the cache even if the channel founder auth mode
3421 is set when there are no users anymore on the channel. Affected
3422 file silcd/server.c.
3424 * The silc_net_localhost now resolves the entire hostname including
3425 the domain name. Affected file lib/silcutil/silcnet.c.
3427 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Changed the ask_passphrase client operation to be ascynchronous.
3430 It has now a completion callback and a context that the
3431 application must call after it has got the passphrase from
3432 the user. Affected files lib/silcclient/silcapi.h,
3433 lib/silcclient/protocol.c, lib/silcclient/command.c and
3436 Added SilcAskPassphrase callback that the application calls
3437 to deliver the passphrase to the library.
3439 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3440 The public key verification and especially a certificate
3441 verification is asynchronous procedure.
3443 Added new SILC_SKE_STATUS_PENDING status to indicate the
3444 request is pending and a callback will be called to finalize
3447 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3448 indicate that remote end did not send its public key (or
3449 certificate), even though we require it. Added check for this
3450 condition in the SKE. This was a security bug, now fixed.
3452 Defined new SilcSKEVerifyCbCompletion callback that is called
3453 when the verification process is completed.
3455 The affected files lib/silcske/silcske_status.h and
3456 lib/silcske/silcske.[ch].
3458 * Changed the verify_public_key client operation to be async
3459 as well. Defined SilcVerifyPublicKey callback that is used to
3460 indicate the success of the public key verification process.
3462 Changed the server and client to use the new async client
3465 * Changed the Irssi SILC client's internal scheduler to be called
3466 twice as many times as it used to be. As a result the client
3467 should be a bit faster now. Affected file is
3468 irssi/src/silc/core/silc-core.c.
3470 * Added support to Irssi SILC client of asynchronous public key
3471 verification and passphrase inquiry. Affected file is
3472 irssi/src/silc/core/silc-core.c.
3474 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Do not say "You have left channel %s" in client library.
3477 Moved it to the application. Affected files are
3478 lib/silcclient/command.c and silc/client_ops.c.
3480 * Fixed silc_client_get_clients. Command context was not
3481 duplicated and was freed memory in the callback. Affected
3482 file lib/silcclient/idlist.c.
3484 * Do not say "you are now talking..." on JOIN command in the
3485 client library. The appliation must handle it.
3487 * Do not say ".. changed topic to" in command reply in the
3488 client libary. The application must handle it.
3490 * Fixed TOPIC command sending in the client library.
3492 * Fixed a memory leak in silc_client_command_free in the file
3493 lib/silcclient/command.c.
3495 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Imported a modified version of Irssi client to the source tree.
3498 The Irssi will be used to create a new client called
3499 Irssi SILC. Imported to irssi/.
3501 Added silc_core_init_finish function to the Irssi. Affected
3502 file irssi/configure.in.
3504 A lot changes in the Makefile.ams around the irssi tree.
3506 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Do not rehash if the new size is same as the old size of the
3509 hash table, in the silc_hash_table_rehash*. The affected file
3510 lib/silcutil/silchashtable.c.
3512 * Replaced hash_table_del_by_context calls from the server
3513 (when channel->user_list and client->channels) to the
3514 hash_table_del as it is sufficient and faster.
3516 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Added silc_hash_table_list, silc_hash_table_get and the
3519 SilcHashTableList structure to provide an alternative way to
3520 traverse the hash table. The affected files are
3521 lib/silcutil/silchashtable.[ch].
3523 * Changed the server's idlist routines to use the hash table
3524 routines to optimize the code.
3526 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Replaced the client entry's `channel' list and channel entry's
3529 `user_list' list to hash tables for optimized lookup. Changed
3530 the code to use the hash table interface around the code.
3531 Affected file lib/silcd/idlist.[ch].
3533 * Added `auto_rehash' boolean argument to the function
3534 silc_hash_table_alloc to indicate whether the hash table should
3535 auto-rehash when it thinks is appropriate time. It will
3536 increase the hash table size if the there is twice as much
3537 entries in the table than the size of the table, and will
3538 decrease the size if there are twice as less entries than
3539 the size of the table.
3541 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3545 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * silc_idcache_purge_by_context deletes the entry now by context
3548 as it is supposed to do. Affected file lib/silccore/idcache.c.
3550 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3551 client is not anymore valid (WHOWAS givens the info) and not
3552 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3554 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Removed the `data' and `data_len' arguments from the ID Cache
3557 interfaces and added `name' argument. ID Cache does not handle
3558 anymore the binary data only a names associated with given ID.
3560 * When hashing a Client ID with silc_hash_id the entire ID is
3561 not hashed anymore, instead only the hash of the Client ID is
3562 hashed. This way we can access the Client ID from the cache
3563 with Client ID but with the hash of the ID (which is a hash of
3564 the nickname) as well without any difference in performance.
3566 Added also silc_idcache_find_by_id_one_ext to do one on one
3567 searching when we have the actual ID. Added also function
3568 silc_hash_client_id_compare. The affected files are
3569 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3571 * When hashing the name associated with a ID it is always done
3572 in lowercase. This way we can access the cache without worrying
3573 about case-sensitivity, even though, for example nicknames are
3576 * Fixed a bug in server with channel message sending. It put
3577 wrong ID type as destination ID. The affected file
3578 silcd/packet_send.c.
3580 * silc_idcache_del_by_context now deletes from all hash tables
3581 by context. Affected file lib/silccore/idcache.c.
3583 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Changed the client library to use the new ID Cache interface.
3586 Changes around the source tree.
3588 * Added silc_hash_table_rehash_ext to rehash with specific
3589 hash function. Affected file lib/silcutil/silchashtable.[ch].
3591 * Added silc_hash_string_compare to compare two strings in the
3592 hash table. Affected file lib/silcutil/silcutil.[ch].
3594 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Added new function silc_idcache_del_by_context into the
3597 lib/silccore/idcache.[ch].
3599 * Changed the server's ID list routines to use the new ID Cache
3600 interface. Changes around the source tree.
3602 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Added silc_hash_table_del[_by_context]_ext functions in to the
3605 lib/silcutil/silchashtable.[ch].
3607 Removed silc_hash_table_find_all* routines and added new
3608 silc_hash_table_find_foreach to replace them.
3610 Added silc_hash_table_replace_ext function as extended
3611 replacing function. Separated the simple hash table interface
3612 from the extended hash table interface in the file
3613 lib/silcutil/silchashtable.h.
3615 * Fixed minor bugs and changed it to use some of the new
3616 hash table functions in lib/silccore/idcache.c
3618 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Added new function silc_hash_table_find_all to return all keys
3621 in the hash table by the specified key. As the hash table is
3622 collision resistant it also makes it possible to have several
3623 duplicate keys in the hash table. This function may be used to
3624 find all of the keys from the hash.
3626 Added user_context arguments to the SilcHashFunction,
3627 SilcHashCompare and SilcHashDestructor to deliver user specified
3630 Added new fuctions silc_hash_table_find[_all]_ext to do
3631 extended lookup with specified hash and compare functions and
3632 specified user contexts.
3634 Added new function silc_hash_table_add_ext to add the key
3635 with specified hash function and user context.
3637 Added new function silc_hash_table_foreach to traverse all
3638 entrys in the hash table. Added SilcHashForeach callback
3641 Added new function silc_hash_table_del_by_context to delete
3642 the entry only if the context associated with the key matches.
3644 Affected files are lib/silcutil/silchashtable.[ch].
3646 * Removed silc_hash_[server/client/channel]_id and added just
3647 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3648 silc_hash_id_compare to compare two ID's using as the hash table
3649 comparison function. Added also silc_hash_data to hash
3650 binary data and silc_hash_data_compare to compare it.
3652 * Removed silc_idlist_find_client_by_hash as it is not needed
3653 anymore. Affected file silcd/idlist.[ch].
3655 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3656 to use internally the SilcHashTable. The new ID Cache is a lot
3657 faster than the old one. Some of the ID Cache interface was also
3658 rewritten and obsolete and stupid functions were removed.
3660 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Added entry_count field to the SilcHashTable to keep the number
3663 of the entries in the table. Implemented the function
3664 silc_hash_table_rehash. Added new function
3665 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3667 Fixed a minor bug in silc_hash_table_free.
3669 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3670 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3671 into the lib/silcutil/silcutil.[ch].
3673 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Implemented a collision resistant hash table into the
3676 lib/silcutil/silchashtable[ch]. See the header and the source
3677 for the SilcHashTable API.
3679 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Merged dotconf version 1.0.2 into lib/dotconf.
3683 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Do not compile anything in lib/silcsim/* if the SIM support
3686 is not enabled. The tree should now compile without problems
3689 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Compiled the SILC under cygwin. Compiled and tested briefly
3692 without problems. More tests needed. The SIMs didn't compile
3695 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3697 * Fixed possible crash in silc_get_username in the
3698 lib/silcutil/silcutil.c.
3700 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Fixed a va_arg in silc/client_ops.c.
3704 * Oops, RC5 routines were named AES and caused some problems
3705 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3707 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Added new SilcIDIP structure into the lib/silccore/id.h and
3710 replaced the old `ip' fields from all SILC ID's to that type.
3711 This is a step towards IPv6 support.
3713 The silc_id_get_len takes now the ID as an extra argument.
3714 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3715 both IPv4 and IPv6 based ID's.
3717 The affected files are lib/silccore/id.[ch] and other files
3718 around the tree using these routines.
3720 * Removed the ID length arguments in server from various
3721 silc_server_send_notify_* routines -> they are not needed
3724 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Fixed memory leak in silc_encode_pem_file in the file
3727 lib/silcutil/silcutil.c.
3729 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Check minor version as well in the SKE. Affected files are
3732 silcd/protocol.c and lib/silcclient/protocol.c.
3734 * Added --identifier option to the server so that an identifier
3735 can be when creating the public key for the server. Affected
3736 file is silcd/silcd.c.
3738 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3739 lib/silccrypt/silcpkcs.c.
3741 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Register default ciphers and stuff when using -C option with
3744 the server. Affected file sildc/silcd.c.
3746 * Put back the servers public key filename format, it is better
3747 than the new one. For now, the client keys are saved with the
3748 new filename format. The affected file silc/client_ops.c.
3750 * Implemented the Cipher API for the rest of the ciphers that
3751 did not implement it or implemented it the wrong way.
3753 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Register default ciphers and stuff when using the -S option
3756 in the client. Affected file silc/silc.c. Same also when
3757 creating new key pair with -C option.
3759 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Fixed the silc_verify_public_key client operation function to
3762 save the public keys differently. The fingerprint is now
3763 used as filename and not the hostname. This way also the
3764 client keys are saved uniquely and not with hostnames. The
3765 affected file is silc/client_ops.c.
3767 * Trimmed the silc_hash_fingerprint function to remove extra
3768 whitespaces from the end of the fingerprint. The affected
3769 file is lib/silccrypt/silchash.c.
3773 * Added silc_cipher_register_default function to register all
3774 default ciphers. It can be used when configuration files
3775 does not exist and the application does not want any specific
3776 ciphers in any specific order.
3778 The SilcDList is now used as silc_cipher_list dynamically
3779 allocated cipher list. Removed the static list all together
3780 and now all ciphers must be allocated to the dynamic list.
3781 The silc_cipher_alloc routine was changed to check only the
3784 All silc_cipher_* routines that used to return int returns
3787 The affected files lib/silccrypt/silccrypt.[ch].
3789 * The same thing was done to silc_hash_* as for silc_cipher_*
3790 routines. Affected files lib/silccrypt/silchash.[ch].
3792 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3793 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3794 Added also silc_pkcs_[un]register[_default] functions.
3795 Removed the data_context from the PKCS API.
3797 * Added silc_hmac_register_default function to register default
3798 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3799 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3800 to unregister all hmacs at once.
3802 * Register the default ciphers, hash functions, PKCSs and HMACs
3803 if client's configuration file does not exist. The affected
3806 * The client did not load the hash functions from the SIM
3807 modules at all. Added support for this. Affected file is
3808 silc/clientconfig.c.
3810 * When decoding public key with silc_pkcs_public_key_decode, check
3811 the supported algorithm only if PKCS are registered. Affected
3812 file lib/silccrypt/silcpkcs.c. The same was done with the
3813 silc_pkcs_private_key_decode.
3815 * Fixed the SILC List routines to keep the list always in order.
3816 It used to change the list's order when traversing the list but
3817 not it preserves the order. Affected file lib/trq/silclist.h.
3819 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added the client library to use the SilcSocketConnection's
3822 reference counter (by silc_socket_dup) to prevent the bug that
3823 the socket object may be freed underneath async operation.
3825 * The name resolv library checking fixes in the configure.in.pre.
3828 * Created new version of the protocol drafts for future
3829 development. The -03 drafts are the ones that will be changed
3830 in the trunk now and the -02 will remain as they are.
3832 * Send list of CUMODE notifys to the router when announcing
3833 the channel users to the router. Affected file silcd/server.c.
3834 If the router receiving channel founder CUMODE for a channel
3835 that already has channel founder it will send CUMODE notify
3836 to the sender to remove the channel founder rights from the
3837 announced client. Affected file silcd/packet_receive.c.
3839 * The CUMODE notify may now use Server ID as well as the entity
3840 who changes the mode. Updated protocool specs.
3842 * Updated INSTALL and README files.
3844 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * New web pages in the http://silc.pspt.fi. The pages was
3851 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Implemented the [DenyConnectin] config section in the server.
3854 Added silc_server_config_denied_conn to check whether incoming
3855 connection is denied. Affected file silcd/serverconfig.[ch].
3857 * Do not check the ports when checking the incoming configuration
3858 data if the port is 0, meaning any. Affected file is
3859 silcd/serverconfig.c.
3861 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Fixed buffer overflow in silc_string_compare in the file
3864 lib/silcutil/silcutil.c.
3866 * Fixed double free in silc_server_command_leave in the file
3869 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Fixed the version checking in the server. Affected file is
3874 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Fixed the configuration data fetching when accepting new
3877 connections in the server. Affected file silcd/server.c.
3879 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Added `sender_entry' argument to the function
3882 silc_server_packet_relay_to_channel so that we can check
3883 whether some destination actually belongs to the same route
3884 the sender belongs (ie, we must not resend the packet to the
3885 sender). Affected file silcd/packet_send.[ch].
3887 * Added `servername' field to the SilcClientEntry in the server
3888 to hold the name of the server where client is from. Affected
3889 file is silcd/idlist.h.
3891 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Moved the channel message encrypting in the router betwen
3894 router connections from silc_server_channel_message to the
3895 silc_server_packet_relay_to_channel since we want to check
3896 whether we have anybody channel before encrypting anything.
3897 Affected files silcd/packet_[receive/send].c.
3899 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Fixed the [AdminConnection] server config section to support
3902 multiple entries. Affected file silcd/serverconfig.c.
3904 * Added support into the server to check the validity of the
3905 incoming connection before executing any KE or authentication
3908 * The connection configuration is now saved to the KE and
3909 connection auth protocol contexts and not fetched anymore in
3910 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3912 * The local hosts listenning address and port is also resolved
3913 now when starting the server. We want to have the socket object
3914 to include the real address and port for the listener. Added
3915 new function silc_net_check_local_by_sock into the files
3916 lib/silcutil/silcnet.[ch].
3918 * Fixed a broadcast bug in server -> do not broadcast if we
3921 * Fixed a routing bug. Do not route broadcast packets ever.
3922 Broadcast packets must be processed always and not routed since
3923 they may be destined to some other host than yourself and thus
3924 would get routed without no good reason. Affected file is
3927 * Added function silc_server_config_is_primary_route to check
3928 whether primary router connection has been configured (a router
3929 configuration that we are initiating). If there is not, we
3930 will assume that there is only two routers in the SILC network
3931 and we will use the incoming router connection as our primary
3932 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3934 * Changed the order of the broadcasting. Broadcast _after_ the
3935 packet has been processed not before. Affected file is
3938 * Fixed a [ClientConnection] parsing bug. The port was never
3939 parsed correctly thus resulting to port 0. Affected file
3940 silcd/serverconfig.c.
3942 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3943 argument and did not set the broadcast packet flag. Affected
3944 file silcd/packet_send.c. Fixed same bug in the function
3945 silc_server_send_notify as well.
3947 * If we receive NEW_ID packet for our own ID in the server, ignore
3950 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Removed the nickname from the Private Message Payload.
3955 Updated the code and the protocol specs.
3957 * Updated protocol specs for submitting to the IETF.
3959 * Tweaked the Random Number Generator a bit. Affected file
3960 lib/silccrypt/silcrng.c. Exported a new function
3961 silc_rng_[global]_add_noise which can be used to add more
3964 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Do not parse packets with different timeout when protocol
3967 is active -> may cause problem with rekey. Affected file
3970 * When server receives signoff notify it must not create
3971 new channel key if the client is on any channels since the
3972 sender of the signoff notify will create it.
3974 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added printing of error messages during SKE protocol from the
3977 failure packet sent by server during SKE. Affected file
3980 * Removed the client's failure_callback handling with timeout
3981 and handle it immediately when received.
3983 * The SKE library returned wrong type in SUCCESS and FAILURE
3984 packets. They must be 32 bit MSB not 16 bit MSB.
3986 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Ok, rewrote the logic of the re-key and now it seems to work.
3989 I tested it on high traffic with frequent re-keys without
3990 problems. Added hmac_receive (and renamed hmac to hmac_send)
3991 in SilcClientConnection in lib/silcclient/client.h and
3992 in SilcIDListData in silcd/idlist.h. Also, removed the
3993 SilcPacketParserContext's cipher and hmac fields as they are
3994 not needed anymore and actually caused some problems when
3995 the ciphers and hmac's changed underneath the packet parser.
3997 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * If re-key protocol is active then process the incoming packets
4000 synchronously since we must assure that icoming packets encrypted
4001 with the old key is processed before the new keys is set to
4002 use. This is true other packets than for REKEY packets.
4003 Affected file silcd/server.c. The same was done to client library
4004 as well, affected file lib/silcclient/client.c.
4006 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Fixed bug in client and server to accept the force send if
4009 the packet is send from silc_[server/client]_packet_process
4010 function. Otherwise the packets are never delivered, oops.
4012 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Disable force sending of packets when REKEY protocol is active.
4015 We must assure that no packet is sent directly when rekey is
4016 performed. All packets must be sent through packet queue.
4017 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4018 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4019 function is silc_[server/client]_packet_send_real to check
4022 * Replaced the SIM paths from example config files to
4023 /usr/local/modules. Also, make install creates now
4024 /usr/local/silc/logs directory to hold all the SILC server
4027 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Made the configure.in.pre work on Solaris. Patch by salo.
4031 * Made all ciphers compatible with non-x86 machines. Defined
4032 CBC mode macros into lib/silccrypt/ciphers_def.h.
4034 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Fixed the make install.
4038 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * When MAC computation fails the silc_packet_decrypt returned 0
4041 even though it was supposed to return -1. Fixed this. The
4042 affected file is lib/silccore/silcpacket.c.
4044 * Do not replace the config files in /etc/silc (in make install)
4045 if they already exist. Affected file ./Makefile.am.
4047 * Do not send re-key packets immediately but through packet queue.
4048 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4050 * Changed silc_net_check_host_by_sock to return FALSE if the
4051 IP/DNS could not be resolved. Though, it returns the IP address
4052 now even if it could not resolve it (but returns also FALSE).
4053 Affected file lib/silcutil/silcnet.[ch].
4055 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Added silc_pkcs_decode_identifier to decode the public key's
4058 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4059 Added also silc_pkcs_free_identifier. Added also new context
4060 SilcPublicKeyIdentifier.
4062 * Added -S option to the silc client. It is used to dump the
4063 contents of the specified public key file.
4065 * Changed the PKCS api to return the public key length when
4066 setting the public key.
4068 * Fixed a fatal bug in the public and private key file loading.
4069 Affected file lib/silccrypt/silcpkcs.c.
4071 * Execute the packet parsing for client with zero (0) timeout
4072 if the protocol is active. Affected file silcd/server.c.
4074 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Made the key generation options to the silcd program. Added
4077 -C option, equivalent to client's option.
4079 * Added new [ServerKeys] config section to the server. It
4080 configures the server's public and private key.
4082 * Defined generic Public Key Payload into the protocol
4083 specification to send specific type of public keys and
4086 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4087 public key or certificate.
4089 * Implemented the GETKEY command to the server and to the
4090 client library and on user interface.
4092 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Made preliminary `make install' work.
4096 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Added SilcServerRekey context into silcd/idlist.h.
4100 * Added the PFS support as defined in the specification to the
4101 SKE protocol. Affected files lib/silcske/*.c.
4103 * Added `ske_group' field to the SilcServerRekey context to hold
4104 the number of the SKE group that is used with PFS in re-key.
4105 Affected file silcd/idlist.h.
4107 * Added PFS re-key support to the server. Affected file is
4110 * Added silc_protocol_cancel to cancel execution of the next
4111 state of the protocol. Affected file is
4112 lib/silccore/silcprotocol.[ch].
4114 * Added the re-key support with and without PFS to the client
4115 library. Re-key is performed once in an hour, by default.
4117 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4118 Added silc_client_rekey_callback and silc_client_rekey_final.
4119 Affected files are lib/silcclient/protocol.[ch] and
4120 lib/silcclient/client.[ch].
4122 * Removed the `hmac_key' and `hmac_key_len' fields from the
4123 SilcClientConnection structure; not needed. Affected file is
4124 lib/silcclient/client.h.
4128 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Do not ask whether user wants to use the negotiated private key
4131 for private messages, just use it. Affected file is
4132 silc/local_command.c.
4134 * Added `send_enc_key' and `enc_key_len' fields to the
4135 SilcIDListData structure since they are needed in the re-key
4136 phase. Affected file is silcd/idlist.[ch].
4138 * Implemented the simple re-key protocol into the server.
4139 Affected files silcd/server.c and silcd/protocol.[ch]. The
4140 re-key will be performed once in an hour, by default.
4142 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4143 Added silc_server_rekey, silc_server_rekey_callback and
4144 silc_server_rekey_final.
4146 * Removed Tunneled flag from the protocol. Updated the code
4147 and the specifications.
4149 * Adde `pfs' field to the SilcIDListData to indicate whether
4150 the PFS is to be performed in the re-key. Affected file is
4153 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4156 int64 of at least the xintXX size. If void * is less that 4
4157 bytes uint32 * will be used. Defined bool as boolean.
4159 * Changed _ALL_ unsigned long and unsigned int to uint32,
4160 unsgined short to uint16 in the source tree.
4162 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4163 not handle clients that has entry->data.registered == FALSE.
4164 They are not in the network anymore. Affected file is
4167 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Implemented the sending of the SERVER_SIGNOFF notify in the
4170 server. Affected file is silcd/server.c.
4172 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4173 Added also silc_notify_payload_encode_args into the
4174 lib/silccore/silcnotify.[ch].
4176 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4177 Affected file silcd/packet_receive.c.
4179 * Implemented the SERVER_SIGNOFF notify handling in the client
4180 library. Affected file lib/silcclient/client_notify.c. Also,
4181 implemnted the printing of the SERVER_SIGNOFF info to the
4182 application. Affected file silc/client_ops.c.
4184 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4185 if the deleting was successful. Affected file silcd/idlist.[ch].
4187 * Added support for public key authentication in the connection
4188 authentication protocol in the client library. Affected file
4189 lib/silcclient/protocol.c.
4191 * Changed the server's silc_idlist_get_clients_by_* interface
4192 to support already allocated array so that new entries may be
4193 added to pre-allocated array. Affected file silcd/idlist.[ch].
4194 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4195 and command replies.
4197 * All command reply functions in the server now calls the
4198 pending command callback even if error occured. This way the
4199 error will be delivered to the client as well. Affected files
4200 silcd/command.c and silcd/command_reply.c.
4202 * Fixed INFO command to return local server's info if no server
4203 was provided. Affected file lib/silcclient/command.c.
4205 * Removed RESTART command for good. Updated the code and the
4208 * Rewrote parts of the task system. It is a bit simpler now.
4209 Removed unsued task priorities. The affected files are
4210 lib/silcutil/silctask.[ch].
4212 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Moved the USERS printing from the library to the application.
4215 Affected files lib/silcclient/command.c and silc/client_ops.c.
4217 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Added channel key re-key support. The re-key is perfomed
4222 only by the router and is done once in an hour. Added `rekey'
4223 field to the SilcChannelEntry in the server. Affected files
4224 silcd/server.c and silcd/idlist.h.
4226 * Added silc_task_unregister_by_context into the file
4227 lib/silcutil/silctask.[ch].
4229 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added SILC_UMODE_GONE mode to indicate when the client is not
4232 present in the SILC network. Added also support to the local
4233 command AWAY that will set this mode. Added support of showing
4234 "xxx is gone" in WHOIS command. The USERS command shows the
4235 gone status as well.
4237 * Fixed setting server and router operator privileges in the
4238 server's UMODE command. Affected file silcd/command.c.
4240 * Merged the SKE KE1 and KE2 payloads into one payload. The
4241 new KE payload is equivalent to the old KE2 payload.
4243 Cleaned up the SKE Start Payload parsing. It now uses the
4244 simple buffer unformatting to do the parsing. A lot faster
4247 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4248 to the SKE that is used to indicate whether both of the SKE
4249 parties should perform authentication. By default only the
4250 responder performs authentication. By setting this flag also
4251 the initiator must do authentication. By default it is unset
4252 since in normal SKE case, client to server connection, only
4253 the responder should do authentication. When doing SKE between
4254 two clients both should perform authentication. Updated the
4255 code and the protocol specs.
4257 * A little fix to IDENTIFY command in the server. Search the
4258 client first by hash not nickname. Affected file is
4261 * Fixed the silc_client_close_connection to support closing
4262 the client to client connections wihtout deleting too much
4263 data. Affected file lib/silcclient/client.c.
4265 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4266 are received if protocol used to be active but is not anymore
4267 the application would crash due to NULL pointer dereference.
4268 Affected files silcd/server.c and lib/silcclient/client.c.
4270 * Added `hash' field to the SilcClientConnection to include
4271 the hash function negotiated in the SKE protocol.
4273 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4274 to set the channel founder authentication data. A client can
4275 claim the founder rights later by providing the authentication
4276 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4277 This way the channel founder can regain the channel founder
4278 privileges even it is left the channel. This works only on
4279 local server and the client must be connected to the same
4280 server to be able to regain the founder rights. Updated the
4281 protocol specs accordingly.
4283 Added support to the CMODE command in the client to set the
4284 founder auth data. Read the README to see how to set it.
4286 Added support to the CUMODE command to claim the founder
4287 rights. Read the README to see how to do it.
4289 Added support for the founder authentication to the Channel
4290 Entry in the server. Affected file silcd/idlist.h.
4292 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4293 server's CMODE command. Affected file silcd/command.c.
4295 * Added the following new functions into lib/silccore/silcauth.[ch]:
4296 silc_auth_get_method and silc_auth_get_data.
4298 * The server now saves the remote hosts public key to the
4299 SilcIDListData pointer. Affected file silcd/protocol.c.
4301 * The normal server now does not remove the channel entry from
4302 the cache if the founder authentication data is set. It used
4303 to remove it if the founder was the last one on the channel on
4304 the server and left the channel. The auth data is saved and
4305 if the channel is re-joined later the old entry is used with
4306 the old auth data. Affected files silcd/command_reply.c and
4309 * Removed the `pkcs' field from the SilcIDListData structure
4310 in the server; it is not used. Affected file silcd/idlist.h.
4312 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Fixed packet processing on slow links. Partial packets were
4315 never re-processed because the incoming data buffer was cleared
4316 by the application. Application must not directly clear the
4317 sock->inbuf, the packet processing routines handle it. Fixed
4318 this in client library and in server.
4320 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Fixed the WHOIS and IDENTIFY send reply function to really
4323 check whether to send list or just one entry. Affected file
4326 * Cleaned up the LEAVE command's channel key distribution. The
4327 affected file silcd/command.c.
4329 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4330 can enforce the channel mode as well. In that case the ID
4331 includes the ID of the server. The code now enforces the
4332 mode change if the router have different mode than the server.
4334 * The notify client operation with CMODE_CHANGE notify can now
4335 return NULL client_entry pointer if the CMODE was not changed
4336 by client. Application must check for this.
4338 * Added <Server ID> argument to INFO command to support server
4339 info fetching by Server ID.
4341 * Added silc_server_announce_get_channel_users to get assembled
4342 packets of channel users of the specified channel. Affected
4343 file silcd/server.[ch].
4345 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4346 was freed underneath the ID Cache.
4348 * Re-announce clients when the server received CHANNEL_CHANGE
4349 notify from the router. Affected file silcd/packet_send.c.
4351 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4354 crashed since it did not handle the fact that there is no cipher
4355 called "3" and didn't check the error condition. Now fixed.
4357 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4358 flag. It can be used to send message requests.
4360 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Implemented the RESTART command in the client.
4364 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4365 notice type messages. Added notice printing to the user
4368 * The channel keys are not re-generated if the channel's mode
4369 is PRIVKEY, ie private key on the channel exists. Affected
4370 files silcd/server.c and silcd/command.c.
4372 * Fixed a little bug in channel message delivery when channel
4373 private keys are set in the server. Affected file is
4374 silcd/packet_send.c.
4376 * Changed the setting on channel->on_channel = TRUE from the
4377 silc_client_save_channel_key to the JOIN command reply. The
4378 key payload is not received if the private channel key is set.
4379 Affected file lib/silcclient/command_reply.c and the
4380 lib/silcclient/client_channel.c.
4382 * When the CMODE_CHANGE notify is sent and the channel private
4383 key mode is removed the channel key must be re-generated in
4384 other cells as well. Added this support for the router in the
4385 silcd/packet_receive.c.
4387 * Added new local command NOTICE to send notice message on
4388 channel. Affected file silc/local_command.[ch].
4390 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Added new local command ME to the client. It is used to send
4393 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4394 some action. Affected file silc/local_command.[ch].
4396 * Changed channel_message and private_message client operations
4397 to deliver the message flags to the application. Added also
4398 the `flags' arguments to the silc_client_send_channel_message
4399 and silc_client_send_private_message functions. Affected file
4402 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Redefined the Private Message Payload to support private message
4405 keys and to support the new private message flags. Updated
4406 the protocol specs. Flags makes it possible to have for example
4407 CTCP style messages.
4409 * Added new type SilcPrivateMessagePayload and defined an API
4410 for it in the lib/silcclient/silcprivate.[ch].
4412 * Tested private message private keys successfully. Tested the
4413 private message key set, unset and list commands with the new
4416 * Redefined the Channel Message Payload to include the channel
4417 message flags (equal with private message flags) to support
4418 for example CTCP style messages.
4420 * Defined some of the message (for channel and private message)
4421 flags. Updated the protocol specs and added the flags to the
4422 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4424 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Added SilcKeyAgreementStatus type to the key agreement routines
4427 to indicate the current status and error if one occured.
4428 The status types are defined in the lib/silcclient/silcapi.h.
4430 * Added new local command KEY that is used to set and unset private
4431 keys for channels, set and unset private keys for private messages
4432 with remote clients and to send key agreement requests and
4433 negotiate the key agreement protocol with remote client. The
4434 key agreement is supported only to negotiate private message keys,
4435 it currently cannot be used to negotiate private keys for channels,
4436 as it is not convenient for that purpose.
4438 * Fixed a minor pending callback setting bug in the function
4439 silc_client_get_client_by_id_resolve, now the function works.
4440 Affected file lib/silcclient/idlist.c.
4442 * Added function silc_net_get_local_port to get local bound
4443 port by socket. Added to lib/silcutil/silcnet.[ch].
4445 * Added `sockets' and `sockets_count' fields to the SilcClient
4446 object. They hold the sockets of the listenning sockets in
4447 the client. Listenning sockets may be for example the key
4448 agreement server. Affected file lib/silcclient/client.[ch].
4449 Added functions the silc_client_add_socket and the
4450 silc_client_del_socket. They are exported to the application
4453 * Added ~./silc/clientkeys to support other client's public keys.
4455 * Renamed verify_server_key client operation to verify_public_key
4456 and added one argument to indicate the type of the connection
4457 (server, client etc.).
4459 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Added silc_server_connection_auth_request to handle the
4462 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4463 silcd/packet_receive.[ch].
4465 * Added silc_server_send_connection_auth_request into the
4466 silcd/packet_send.c to send the connection auth request packet.
4468 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4471 * Fixed the public key authentication in responder side in the
4472 server. The `auth_data' pointer includes the SilcPublicKey
4473 not the path to the public key. Affected file silcd/protocol.c.
4475 * Implemented the public key authentication in the initiator side
4476 in the server. Affected file silcd/protocol.c.
4478 * Removed the [RedirectClient] config section from the server
4479 configuration. Is not needed and I don't want to implement it.
4481 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Cleaned up the CMODE command in the server. It now works
4484 correctly and supports all the modes defined in the protocol.
4485 Affected file is silcd/command.c.
4487 * Added `hmac_name' field to the SilcChannelEntry in the server
4488 to hold the default HMAC of the channel. It can be set when
4489 creating the channel (with JOIN command). Affected files
4492 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4493 type to indicate the change of the current cipher and hmac
4494 on the channel. Client can safely ignore the <cipher> argument
4495 (if it chooses to do so) since the CHANNEL_KEY packet will
4496 force the channel key change anyway. The <hmac> argument is
4497 important since the client is responsible of setting the new
4498 HMAC and the hmac key into use.
4500 * Fixed the CMODE command in the client library as well.
4502 * Tested CMODE command in router environment successfully.
4504 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Show the version of the remote client (or server) when connecting
4507 to the server. It is logged to the log file. Affected file
4508 is silcd/protocol.c.
4510 * Fixed the KILLED notify handling in the client library. The
4511 client must be removed from all channels when receiving the
4514 Also, do not remove the client entry when giving the KILL
4515 command but when the KILLED notify is received.
4517 * Removed silc_idlist_find_client_by_nickname from the server.
4518 Not needed anymore. Affected files silcd/idlist.[ch].
4520 * Implemented the CHANNEL_CHANGE notify type handling to the
4521 server. Affected file silcd/server.c.
4525 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added silc_server_send_notify_invite to send the INVITE
4528 notify between routers.
4530 * Implemented the INVITE command correctly to the server.
4532 * Implemented the INVITE notify type handling in the server.
4534 * Implemented the INVITE command to the client library and on the
4537 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Added function silc_server_get_client_resolve to find the
4540 client entry by ID from all ID lists and then resolve it
4541 (using WHOIS) if it cannot be found. Affected file is
4544 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Implemented the BAN command to the client library.
4548 * The JOIN command in the server now checks the invite list
4551 * Changed the silc_command_reply_payload_encode_va and the
4552 silc_command_payload_encode_va to support that if argument is
4553 NULL it ignores and checks the next argument. Affected file
4554 lib/silccore/silccommand.c.
4556 * Added silc_server_send_notify_ban to send the BAN notify
4557 type between routers.
4559 * Chaned the silc_notify_payload_encode to support that if
4560 argument is NULL it ignores and checks the next argument.
4561 Affected file lib/silccore/silcnotify.c.
4563 * Tested ban lists in router environment successfully.
4565 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Implemented BAN command to the server, in silcd/command.[ch].
4569 * Removed the BAN and INVITE_LIST modes from the CMODE command
4572 * Added function silc_string_match to regex match two strings.
4573 Affected files lib/silcutil/silcutil.[ch].
4575 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Redefined parts of the SilcChannelEntry in the server to support
4578 the new ban and invite lists.
4580 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Redefined the INVITE command. The same command can be used to
4583 invite individuals to the channel but also to manage the invite
4584 list of the channel (to add to and remove from the invite list).
4585 Updated the protocol specs.
4587 * Added new command SILC_COMMAND_BAN that can be used to manage
4588 the ban list of the channel. Updated the protocol specs.
4590 * Removed the channel modes: the SILC_CMODE_BAN and the
4591 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4592 in the CMODE command. The equivalent features are now available
4593 using INVITE and BAN commands. Updated the protocol specs.
4595 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4596 in the network about change in the current ban list. The notify
4597 type is not used by the client.
4599 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4600 support the invite lists.
4602 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Added new function silc_string_regexify that converts string
4605 including wildcard characters into regex string that can
4606 be used by the GNU regex library. Added into the file
4607 lib/silcutil/silcutil.[ch].
4609 Added silc_string_regex_combine to combine to regex strings
4610 into one so that they can be used as one regex string by
4611 the GNU regex library. Added into the file
4612 lib/silcutil/silcutil.[ch].
4614 Added silc_string_regex_match to match two strings. It returns
4615 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4617 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Imported GNU regex to the soruce tree into lib/contrib.
4620 Fixed some compiler warning from the regex.c.
4622 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Fixed MOTD command in the server to work in router environment.
4626 * Fixed the MOTD command in the client library to support
4627 the server argument in the command.
4629 * Added `nickname_len' argument to the silc_idlist_add_client
4630 in the server, as the `nickname' argument may be binary data
4633 * Added silc_idlist_get_channels to return all channels from
4636 * Implemented LIST command to the server. Affected file is
4639 * Implemented the LIST command to the client library and on the
4642 * Added [<user count>] argument to the LIST command reply.
4643 With private channels the user count is not shown.
4645 * Updated TODO and README.
4647 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * The client entry's data.registered must be TRUE even with
4650 global client entry on global client list. The data.registered
4651 is used to check whether the client is anymore in the network,
4652 for example with WHOWAS command so it must be valid.
4654 * Fixed the WHOWAS command in the server. It now actually works
4655 in router environment. Added function into silcd/command_reply.c
4656 silc_server_command_reply_whowas_save.
4658 * Added silc_idlist_purge function to the silcd/idlist.c
4659 to periodically purge the ID Cache.
4661 * Fixed INFO command in the server. It works now in router
4662 environment. Added <server name> argument to the INFO command
4663 reply. Updated the protocol specs.
4665 * Fixed minor bug in silc_idcache_purge to not purge if the
4666 expire value is zero.
4668 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4669 they were buggy because of the WHOWAS information.
4671 * Fixed local command MSG to handle the async resolving of
4672 the remote client properly. It used to fail the first MSG.
4673 Affected file silc/local_command.c.
4675 * Added `data_len' field to SilcIDCache context.
4677 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Update TODO. Todo in commands in the server.
4681 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4684 used by routers as broadcast packet to inform other routers
4685 about the changed user mode.
4687 Implemented the notify handling in the server. Affected file is
4688 silcd/packet_receive.c. Added the function
4689 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4691 * Added new generic Channel Payload and deprecated the New Channel
4692 Payload. The New Channel Payload is now the generic Channel
4695 * Added new argument `mode' to the silc_server_send_new_channel
4696 as it is required in the Channel Payload now.
4698 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4699 and created a new and real SilChannelPayload to represent the
4700 new generic Channel Payload. Implemented the encode/decode
4701 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4703 * Added silc_server_get_client_channel_list to return the list
4704 of channels the client has joined for WHOIS command reply.
4705 Affected file silcd/server.[ch].
4707 * Implemented the channel list sending in the WHOIS command reply
4708 in server and in the client.
4710 Implemented the channel list displaying on the user interface
4711 as well. Affected file silc/client_ops.c.
4713 * Added silc_channel_payload_parse_list to parse list of Channel
4714 Payloads. It returns SilcDList list of SilcChannelPayloads.
4715 Client for example can use this function to parse the list of
4716 channels it receives in the WHOIS command reply. The caller
4717 must free the list by calling silc_channel_payload_list_free.
4718 Affected files lib/silccore/silcchannel.[ch].
4720 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Added one new argument <user mode> to the WHOIS command reply
4723 to return the mode of the user in SILC. Updated the protocol
4726 Implemented it to the server and client.
4728 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Fixed the mode printing on the user interface on joining.
4731 Affected file silc/client_ops.c.
4733 * Implemented the UMODE command and user modes in general to the
4734 client library and to the user interface.
4736 * Implemented the UMODE command to the server.
4738 * The server now sends UNKNOWN_COMMAND error status if client sends
4739 unknown command. Affected file silcd/command.c.
4741 * All server commands now handle the command identifier the right
4742 way when sending the command reply to the client. The client can
4743 use to identify the command replies with the identifier.
4745 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Added silc_server_get_client_route to resolve the route to
4748 the client indicated by the client ID. Affected file is
4751 * Added silc_server_relay_packet as general function to relay
4752 packet to arbitrary destination. This deprecates functions
4753 like _send_private_message_key, _relay_notify etc. Affected
4754 file is silcd/packet_send.[ch].
4756 Removed silc_server_send_key_agreement,
4757 silc_server_send_private_message_key and
4758 silc_server_packet_relay_notify functions from the file
4759 silcd/packet_send.[ch].
4763 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4764 server. Affected file silcd/packet_receive.[ch].
4766 * Implemented the KILL command to the client. Implemented the
4767 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4768 Affected files lib/silcclient/command[_reply].c and
4769 lib/silcclient/client_notify.c. Implemented the KILL notify
4770 printing in the user inteface.
4772 * Fixed a lot silc_parse_nick memory leaks from the client
4773 library in the file lib/silcclient/command.c.
4775 * Changed the silc_server_send_notify_on_channels's `sender'
4776 argument from SilcSocketConnection to SilcClientEntry to
4777 check the sender as entry and not as connection object and not
4778 to send to the client provided as argument. The affected file
4779 is silcd/packet_send.[ch].
4781 * The notify packets that are destined directly to the client used
4782 to not to be processed by the server. Now changed that and the
4783 server processes all notify packets. After relaying the packet
4784 to the client the notify packet is processed in the server.
4786 * The silc_server_free_client_data now checks whether there is
4787 pending outgoing traffic for the client and purges the data to
4788 the network before removing the client entry.
4790 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4793 an client is killed from the SILC Network. Updated the protocol
4796 Added new function silc_server_send_notify_killed to the
4797 silcd/packet_send.[ch].
4799 * Added function silc_server_packet_relay_notify to relay notify
4800 packets that are destined directly to a client. In this case
4801 the server does not process the notify packets but merely relays
4802 it to the client. Affected file silcd/packet_send.[ch].
4804 Added also silc_server_packet_process_relay_notify to check
4805 whereto relay the notify. Affected file is
4806 silcd/packet_receive.[ch].
4808 * Implemented the KILL command to the server.
4812 * Added the backup schema desgined last fall to the protocol
4813 specs for everyone to see. The specification is in the
4814 *-spec-xx.txt draft and the packet type definitions for the
4815 backup routers is in *-pp-xx.txt draft. Thusly, added also
4816 new packet type SILC_PACKET_CELL_ROUTERS.
4818 * A big security problem in the implementation discovered. The
4819 signoff of an client did not cause new channel key generation
4820 which it of course should've done. The channel keys must be
4821 always re-generated when client leaves (or signoffs) the channel.
4822 The silc_server_remove_from_channels funtion now handles
4823 the channel key re-generation.
4825 * Added `sender' argument to the silc_server_send_notify_on_channels
4826 to not to send the client provided as argument. Affected file
4827 silcd/packet_send.[ch].
4829 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Implemented OPER and SILCOPER commands into the server and
4834 * Added silc_auth_verify and silc_auth_verify_data to verify
4835 the authentication directly from the authentication payload.
4836 It supports verifying both passphrase and public key based
4837 authentication. Affected file lib/silccore/silcauth.[ch].
4839 * Added `hash' field to the SilcIDListData structure. It is the
4840 hash negotiated in the SKE protocol. Affected file is
4843 * Slight redesigning of the SilcAuthPayload handling routines.
4844 Do not send SilcPKCS but SilcPublicKey as argument.
4846 * Implemented the public key authentication support to the
4847 serverconfig. The public key is loaded from the provided path
4848 and saved as authentication data to void * pointer. Thus,
4849 changed the unsigned char *auth_data to void *auth_data;
4851 * Fixed SHUTDOWN command to send the reply before the server
4852 is shutdown. :) Affected file silcd/command.c.
4854 * Fixed fatal bug in CONNECT command. The hostname was invalid
4855 memory and server crashed. Affected file silcd/command.c.
4857 * Fixed fatal bug in CLOSE command. The server_entry became
4858 invalid but was referenced later in the command. Affected file
4861 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Fixed fatal bug in failure packet handling. Server ignored
4864 the failure and thus crashed when it came.
4868 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4871 that the command may be executed only once in (about) 2 seconds.
4872 The old SILC_CF_LAG flag is same but allows command bursts up
4873 to five before limiting.
4875 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4876 server code. Various commands now includes the CF_LAG_STRICT
4877 flag to disallow any kind of miss-use of the command.
4879 * Fixed the silc_buffer_unformat to not to allocate any data
4880 if the length of the data is zero. It used to allocate the
4881 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4883 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Changed the format of AdminConnection configuration section
4886 in the server. Added username of the admin to the format.
4887 Affected files silcd/serverconfig.[ch].
4889 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4890 to return admin configuration data by host, username and/or
4893 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Implemented WHOWAS command to the server. Added the functions:
4897 silc_server_command_whowas_parse,
4898 silc_server_command_whowas_send_reply,
4899 silc_server_command_whowas_from_client and
4900 silc_server_command_whowas_from_server
4902 * Added <Client ID> argument to the WHOWAS command reply. Updated
4903 the protocol specs accordingly.
4905 * Implemented WHOWAS command and command_reply to the client
4908 Implemented the WHOWAS printing on the user interface.
4910 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * Added new argument to the WHOWAS command reply, the real name.
4913 It is an optional argument. Updated the protocol specs.
4915 * Added SilcIDCacheDestructor callback that is registered when
4916 the SilcIDCache is allocated. The callback is called when
4917 an cache entry in the ID Cache expires, or is purged from the
4918 cache. Added into lib/silccore/idcache.[ch].
4920 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4921 to destruct the client entries when the cache entry expires.
4922 Other ID Cache's in server and in the client library ignores
4925 * If the ID Cache entry's `expire' field is zero then the entry
4926 never expires. Added boolean `expire' argument to the
4927 silc_idcache_add function in the lib/silccore/idcache.[ch].
4928 If it is TRUE the default expiry value is used.
4930 * Added silc_server_free_client_data_timeout that is registered
4931 when client disconnects. By default for 5 minutes we preserve
4932 the client entry for history - for WHOWAS command.
4934 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Added support to the server to enforce that commands are not
4937 executed more than once in 2 seconds. If server receives
4938 commands from client more frequently, timeout is registered
4939 to process the commands. Affected file silcd/command.c.
4940 Added new function silc_server_command_process_timeout.
4942 * Changed NICK_NOTIFY handling in client library to check that
4943 if the client's nickname was changed, so there is no need to
4944 resolve anything from the server.
4946 * Removed error printing from the WHOIS and IDENTIFY commands.
4947 If error occurs then it is ignored silently in the client library.
4948 The application, however, may map the received error to
4949 human readable error string. The application currently maps
4950 the NO_SUCH_NICKNAME error to string.
4952 * Made the command status message public to the application. Moved
4953 them from lib/silcclient/command_reply.c to
4954 lib/silcclient/command_reply.h. The application can map the
4955 received command status to the string with the
4956 silc_client_command_status_message function.
4958 * Added check to the server to check that client's ID is same
4959 as the Source ID in the packet the client sent. They must
4962 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Added dist-bzip hook to the Makefile.am to make bzip2
4965 compressed distributions.
4967 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Server now enforces the maximum length for the nickname and
4970 the channel as protocol specification dictates. 128 bytes for
4971 nickname and 256 bytes for channel name.
4973 * Moved the WHOIS printing to the application. The client libary
4974 does not print out the WHOIS information anymore, the application
4975 must do it. Renamed silc_client_command_reply_whois_print to
4976 the silc_client_command_reply_whois_save.
4978 The client's idle time is also sent to the application now, and
4979 the idle is shown on screen.
4981 * Added silc_client_command_reply_identify_save to save the
4982 received IDENTIFY entries.
4984 * Do not check for channel private keys in message sending and
4985 reception if the channel does not have the PRIVKEY mode set.
4986 Affected file lib/silclient/client_channel.c.
4988 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4991 just surfaced after chaning the JOIN procedure.
4993 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Added silc_client_get_clients_by_list to get client entries
4996 from Client ID list, that is returned for example by JOIN
4997 and USERS command replies. The application should use this
4998 function for example when JOIN command reply is received to
4999 resolve the clients already on the channel (library does not
5000 do that anymore as USERS command reply is not used in the JOIN
5001 procedure anymore). Affected files lib/silcclient/silcapi.h and
5002 lib/silcclient/idlist.c.
5004 * JOIN command reply and USERS command reply returns now SilcBuffer
5005 pointers instead of unsigned char pointers when returning
5006 the client list and mode list.
5008 * Added <Client ID> argument to the JOIN command reply, mainly
5009 for the server to identify for which client the command was
5010 originally sent. Updated protocol specs accordingly.
5012 * Added SilcDlist private_key pointer to the SilcChannelEntry
5013 in the client to support the channel private keys. Affected
5014 file is lib/silcclient/idlist.h.
5016 * Added SilcChannelPrivateKey argument to the function
5017 silc_client_send_channel_message so that application can choose
5018 to use specific private ke if it wants to. If it is not provided,
5019 the normal channel key is used, unless private keys are set.
5020 In this case the first (key that was added first) is used
5021 as the encryption key.
5023 * Implemented the support for channel private key handling.
5024 Implemented the following functions:
5026 silc_client_add_channel_private_key,
5027 silc_client_del_channel_private_keys,
5028 silc_client_del_channel_private_key,
5029 silc_client_list_channel_private_keys and
5030 silc_client_free_channel_private_keys
5032 Affected file lib/silcclient/client_channel.c.
5034 * Added the support for the private keys in the channel message
5035 sending and encryption and in the message reception and
5036 decryption. Affected funtions are
5037 silc_client_send_channel_message and silc_client_channel_message.
5039 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Added SKE's key verify callback to the client library's
5042 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5044 * Removed the statement that server (or router) must send USERS
5045 command reply when joining to the channel so that the client
5046 knows who are on the channel. Instead, the client list and
5047 client's mode list is now sent in the JOIN command reply to the
5048 client who joined channel. This is better solution.
5050 * Added function silc_server_get_users_on_channel and function
5051 silc_server_save_users_on_channel to the silcd/server.[ch].
5053 * Removed function silc_server_command_send_users from the
5056 * Do not show topic on the client library anymore. The topic is
5057 sent in the command reply notify to the application and the
5058 application must show the topic now.
5060 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Added client searching by nickname hash into the IDENTIFY and
5063 WHOIS commands in the server as they were clearly missing from
5064 them. Affected file is silcd/command.c.
5066 * Fixed a bug in private message receiving in the client library.
5067 The remote ID was freed and it wasn't supposed, now it is
5070 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Minor fix to the channel payload; allocate the data area, as it
5073 needs to be of specific length.
5075 * If the key agreement port is zero then the operating
5076 system will define the bound port. Affected files are
5077 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5079 * Added new function silc_channel_payload_decrypt into the file
5080 lib/silccore/silcchannel.[ch].
5082 * Moved the channel message etc, check from silc_packet_decrypt
5083 to applications. The library calls now a generic
5084 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5085 when the packet is either normal or special. This was done to
5086 allow more wide range of checking that was not allowed when
5087 the code was in library. Now applications can do virtually any
5088 checks to the packet and return to the library the decision how
5089 the packet should be processed. Affected files are
5090 lib/silccore/silcpacket.[ch].
5092 Added silc_server_packet_decrypt_check to the server and
5093 silc_client_packet_decrypt_check to the client library.
5095 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5096 to send with specified source and destination information.
5098 * Channel message delivery between routers was broken after the
5099 channel key distribution was fixed earlier. The channel key
5100 was used be to distributed to other routers as well which is not
5101 allowed by the protocol. Now this is fixed and channel keys
5102 really are cell specific and the channel message delivery between
5103 routers comply with the protocol specification.
5105 * Fixed various commands in server to check also the global list
5106 for the channel entry and not just the local list. The affected
5107 file silcd/command.c.
5109 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Added assert()s to buffer formatting and unformatting routines
5112 to assert (if --enable-debug) when error occurs. Affected
5113 file: lib/silcutil/silcbuffmt.c.
5115 * Changed to auto-reconnect to check whether the remote host is
5116 router and register the re-connect timeout if it is. It used
5117 to check that whether we are normal server, but router must do
5118 auto-reconnect with another router as well. Affected file
5121 * Removed the [<key len>] option from CMODE command as the cipher
5122 name decides the key length, nowadays. See the defined ciphers
5123 from the protocol specification.
5125 * Added [<hmac>] option to the CMODE command to define the HMAC
5126 for the channel. Added SILC_CMODE_HMAC channel mode.
5128 * Added [<hmac>] option for the JOIN command so that user can
5129 select which HMAC is used to compute the MACs of the channel
5132 * Added Hmac field to the Channel Message Payload. The integrity
5133 of plaintext channel messages are now protected by computing
5134 MAC of the message and attaching the MAC to the payload. The
5135 MAC is encrypted. Now, it is clear that this causes some
5136 overhead to the size of the packet but rationale for this is that
5137 now the receiver can verify whether the channel message decrypted
5138 correctly and also when private keys are set for the channel the
5139 receiver can decrypt the packet with several keys and check from
5140 the MAC which key decrypted the message correctly.
5142 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5143 lib/silccrypt/silccipher.[ch].
5145 * Added silc_hash_len to return the digest length into the
5146 lib/silcrypt/silchash.[ch].
5148 * Rewrote parts of Silc Channel Payload interface in the
5149 lib/silccore/silcchannel.[ch]. The encode function now also
5150 encrypts the packet and parse function decrypts it.
5152 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Fixed a minor formatting bug in the SKE's key material processing.
5155 It actually might have processed the keys wrong way resulting
5158 * Redefined the mandatory HMAC algorithms and added new algorithms.
5159 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5160 and hmac-md5 truncated to 96 bits. The mandatory is now
5161 hmac-sha1-96. Rest are optional (including the one that used
5162 to be mandatory). Rationale for this is that the truncated HMAC
5163 length is sufficient from security point of view and can actually
5164 make the attack against the HMAC harder. Also, the truncated
5165 HMAC causes less overhead to the packets. See the RFC2104 for
5168 * Added new [hmac] configuration section. The SKE used to use
5169 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5170 is of course wrong. The official names that must be proposed in
5171 the SKE are the ones defined in the protocol specification
5172 (hmac-sha1-96 for example). The user can configure any hmac
5173 using any hash function configured in the [hash] section. At
5174 least, the mandatory must be configured.
5176 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5178 * Added HMAC list to the SKE proposal list. It has now both
5179 hash algorithm list and HMAC list. This makes the protocol
5180 incompatible with previous versions. The SKE now seems to work
5181 the way it is supposed to work, for the first time actually.
5183 * Defined plain Hash algorithms to the protocol specification.
5186 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Implemented support for key agreement packets into the server.
5189 Added functions silc_server_key_agreement and
5190 silc_server_send_key_agreement. Other than these functions,
5191 server has nothing to do with this packet.
5193 * Added support for private message key packets into the server.
5194 Added functions silc_server_private_message_key and
5195 silc_server_send_private_message_key.
5199 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5200 called in the protocol's final callback instead in the END
5201 protocol state. This makes a little more sense and in the same
5202 time in client we can use the same protocol routines for normal
5203 key exchange and to key agreement packet handling as well.
5205 * Added to both client's and server's KE protocol context the
5206 SilcSKEKeyMaterial pointer to save the key material. We will
5207 bring the key material to the protocol's final callback by doing
5208 this. The final callback must free the key material.
5210 * Added SKE's packet_send callback into client's KE protocol
5211 context so that the caller can choose what packet sending function
5212 is used. This way we can use different packet sending when
5213 doing normal SKE when doing key agreement packet handling (in
5214 the key agreement packet handling we do not want to encrypt
5217 * Implemented the responder side of the key agreement routines
5218 in the client. The client can now bind to specified port and
5219 accept incoming key negotiation. The key material is passed
5220 to the application after the protocol is over.
5222 * Implemented the processing of incoming Key Agreement packet
5223 in the client. Added function silc_client_key_agreement to
5226 * Implemented the intiator side of the key agreement routines
5227 in the client. The client can now initiate key agreement with
5228 another remote client. The key material is passed to the
5229 application after the protocol is over.
5231 * Created client_keyagr.c to include all the key agreement
5234 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5235 SILC_TASK_CALLBACK except that it is not static.
5237 * Created client_notify.c and moved the Notify packet handling
5238 from the client.[ch] into that file.
5240 * Created client_prvmsg.c and moved all private message and
5241 private message key routines from the client.[ch] into that file.
5243 * Create client_channel.c and moved all channel message and
5244 channel private key routines from the client.[ch] into that file.
5246 * Changed silc_client_get_client_by_id_resolve to resolve with
5247 WHOIS command instead of IDENTIFY command, in the file
5248 lib/silclient/idlist.c.
5250 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Implemented the SKE's responder side to the Client library.
5254 * When FAILURE is received to the protocol do not trust it
5255 blindly. Register a timeout to wait whether the remote closes
5256 the connection as it should do it, only after that process the
5257 actual failure. This was changed to both client and server.
5259 * Added client_internal.h to include some of the structures
5260 there instead of client.h in lib/silcclient/.
5262 * Added function silc_task_unregister_by_callback to unregister
5263 timeouts by the callback function.
5265 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Some "Incomplete WHOIS info" errors has been appearing on the
5268 log files. Took away the entry->userinfo check from WHOIS
5269 reply sending. The entry->userinfo is now " " if client did not
5270 provide one. I thought this was fixed earlier but something
5271 is wrong still. Let's see if the error still appears.
5273 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Fixed a minor bug in the login when the channel key is
5276 re-generated in the server. It used to generate the key in
5277 wrong order and thus caused problems in the channel traffic.
5279 * Fixed a minor bug in channel key distsribution after
5280 KICK command. The key was not sent to the router even though
5283 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Added silc_ske_process_key_material_data as generic routine
5286 to process any key material as the SILC protocol dictates. The
5287 function is used by the actual SKE library but can be used by
5288 applications as well. This relates to the private message keys
5289 and the channel private keys since they must be processed the
5290 same way the normal SILC session keys. The protocol dictates
5291 this. Affected files: lib/silcske/silcske.[ch].
5293 Added also silc_ske_free_key_material to free the
5294 SilcSKEKeyMaterial structure.
5296 * Defined silc_cipher_set_key function to set the key for
5297 cipher without using the object's method function. The affected
5298 files: lib/silccrypt/silccipher.[ch].
5300 * Implemented silc silc_client_add_private_message_key,
5301 silc_client_add_private_message_key_ske,
5302 silc_client_del_private_message_key,
5303 silc_client_list_private_message_keys and
5304 silc_client_free_private_message_keys functions in the
5307 Added functions silc_client_send_private_message_key to send
5308 the Private Message Key payload and silc_client_private_message_key
5309 to handle incoming Private Message Key payload.
5311 * Added Cipher field to the Private Message Key payload to set
5312 the cipher to be used. If ignored, the default cipher defined
5313 in the SILC protocol (aes-256-cbc) is used.
5315 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * Removed lib/silcclient/ops.h file.
5319 Redefined parts of the SILC Client Library API. Created new
5320 file silcapi.h that deprecates the ops.h file and defines the
5321 published Client Library API. Defined also private message key
5322 API and channel private key API into the file.
5324 This is the file that the application must include from the
5325 SILC Client Library. Other files need not be included by
5326 the application anymore.
5328 * Added new key_agreement client operation callback and also
5329 defined the Key Agreement library API for the application.
5331 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5334 is used by clients to request key negotiation between another
5335 client in the SILC network. If the negotiation is started it
5336 is performed using the SKE protocol. The result of the
5337 negotiation, the secret key material, can be used for example
5338 as private message key.
5340 Implemented the Key Agreement payload into the files
5341 lib/silccore/silauth.[ch].
5343 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Redefined ciphers for the SILC protocol. Added some new ciphers
5346 and defined the key lengths for the algorithms. Changed the
5347 code accordingly. The default key length is now 256 bits.
5349 * Fixed SKE key distribution function silc_ske_process_key_material
5350 when the key length is more than 128 bits. The default key
5351 length in SILC is now 256 bits.
5353 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5354 to indicate unsupported algorithm.
5356 * Renamed rijndael.c to aes.c and all functions as well.
5358 * Fixed a long standing channel key setting bug in client library.
5359 Weird that it has never surfaced before.
5361 * Fixed bug in channel deletion. If the entire channel is removed
5362 then it must also delete the references of the channel entry
5363 from the client's channel list as the client's channel entry and
5364 the channel's client entry share same memory.
5366 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Implemented CONNECT and SHUTDOWN commands in the client.
5370 * Implemented CLOSE command to the client.
5372 * Added the function silc_idlist_find_server_by_name into the
5373 files silcd/idlist.[ch].
5375 Added the function silc_idlist_find_server_by_conn into the
5376 files silcd/idlist.[ch].
5378 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * DIE command was renamed to SHUTDOWN. Updated the both code
5383 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5384 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5386 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5389 * Added function silc_server_create_connection function to create
5390 connection to remote router. My server implementation actually
5391 does not allow router to connect to normal server (it expects
5392 that normal server always initiates the connection to the router)
5393 so the CONNECT command is only good for connecting to another
5396 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5399 or some other client was kicked from the channel.
5401 Implemented the handling of the notify type to both client
5404 Implemented silc_server_send_notify_kicked to send the KICKED
5405 notify. It is used to send it to the server's primary router.
5407 * Implemented the KICK command into server and client.
5409 * Added `query' argument to the silc_idlist_get_client function
5410 to indicate whether to query the client from server or not if
5413 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5414 to indicate that the client is not channel founder.
5418 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Removed the rng context from SilcPacketContext structure and
5421 changed that the packet routine uses the Global RNG API.
5423 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Added support for quit message that client can "leave" on the
5426 channel when it quits the SILC. It is ditributed inside the
5427 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5429 Added silc_server_free_client_data that will take the
5430 signoff message as argument.
5432 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5434 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Updated parts of the protocol specification to keep it up
5439 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5442 payloads in one packet.
5444 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5445 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5446 use now the new List flag.
5448 * Also deprecated the following packet types: REPLACE_ID,
5449 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5451 * Added list support for Notify packet in server.
5453 * Added silc_server_send_notify_channel_change to send the
5454 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5455 the silc_server_send_replace_id.
5457 * Added silc_server_send_notify_nick_change to send the
5458 NICK_CHANGE notify type. Deprecates the function
5459 silc_server_send_replace_id.
5461 * Added silc_server_send_notify_join to send the JOIN notify type.
5462 Deprecates the function silc_server_send_new_channel_user.
5464 * Added silc_server_send_notify_leave to send LEAVE notify type.
5465 Deprecates the function silc_server_send_remove_channel_user.
5467 * Added silc_server_send_notify_cmode and
5468 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5469 types. Deprecates the silc_server_send_set_mode function.
5471 * Added SERVER_SIGNOFF notify type to indicate that server has
5472 quit. This means that all clients on the channel from that
5473 server will drop. This can be also used when netsplit happens.
5475 Deprecated REMOVE_ID packet type since it is not needed anymore
5478 Added silc_server_send_notify_server_signoff to send the
5479 SERVER_SIGNOFF notify type. Deprecates the function
5480 silc_server_send_remove_id.
5482 Added also silc_server_send_notify_signoff to send the
5483 SIGNOFF notify type.
5485 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5486 SILC protocol from this day on. Changed the protocol
5487 specification as well.
5489 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5490 notify type. It is used between routers to notify about
5491 topic changes on a channel.
5493 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5496 * Partly updated the protocol specification to comply with the
5497 changes now made. It is still though a bit outdated.
5499 * The JOIN notify type now takes one extra argument <Channel ID>.
5500 The packet used to be destined to the channel but now the
5501 JOIN type may be sent as list thus it is impossible to
5502 destine it to any specific channel. By adding this argument
5503 it is again possible.
5505 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Added CREDITS file. The CHANGES and CREDITS file will appear
5508 in the distribution as well.
5510 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5513 types in the server's silcd/packet_receive.c.
5515 * Implemented CMODE and CUMODE to work in router environment.
5517 * Fixed minor encoding and decoding buglet from the
5518 lib/silccore/silcmode.c.
5520 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5523 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5525 * Changed all SilcConfigServer* and silc_config_server* to
5526 SilcServerConfig* and silc_server_config*, respectively.
5529 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Associated the ID (client or server ID) to the Authentication
5532 Payload to avoid any possibility of forging. Updated the
5533 protocol specification and the code accordingly.
5535 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * The RSA key length is now save to the RsaKey context in the
5538 key generation process in lib/silccrypt/rsa.c. The key length
5539 is now used to figure out the maximum size of the block allowed
5540 to be encrypted/signed.
5542 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5543 is equivalent to the silc_mp_mp2bin but does not allocate any
5546 * Changed silc_mp_mp2bin API to take length argument. If it is
5547 non-zero then the buffer is allocated that large. If zero, then
5548 the size is approximated using silc_mp_sizeinbase, which however
5551 * Created Global RNG API which is global RNG that application can
5552 initialize. After initializing, any routine anywhere in the
5553 code (including library) can use RNG without allocating a new
5554 RNG object. This was done to allow this sort of use of the
5555 RNG in code that has no chance to allocate RNG object. All
5556 applications currently allocate this and many routines in the
5557 library use this. Affected file lib/silccrypt/silcrng.[ch].
5559 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5560 it to use the Global RNG API.
5562 * Defined Authentication Payload into protocol specification that
5563 is used during SILC session to authenticate entities. It is
5564 used for example by client to authenticate itself to the server
5565 to obtain server operator privileges.
5567 Implemented this payload into the lib/silccore/silcauth.[ch].
5568 Implemented also routines for public key based authentication
5569 as the new protocol specification dictates.
5571 Moved definitions of different authentication methods from
5572 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5574 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5575 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5576 silc_pkcs_verify_with_hash functions into the file
5577 lib/silccrypt/silcpkcs.[ch].
5579 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * The client entry's userinfo pointer must be always valid.
5582 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5583 will fail since it requires the userinfo. Now, the userinfo
5584 is allocated as "" if actual userinfo does not exist. Actually,
5585 it must exist and it is totally Ok to drop client connections
5586 that does not announce the userinfo. However, we will make
5587 this workaround for now.
5589 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5590 to return the remote port by socket.
5592 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5595 SILC_SERVER_PENDING_EXEC and added an new macro
5596 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5597 data or when error occurs while processing the pending command.
5599 Added new argument `destructor' into silc_server_command_pending
5600 and to the SilcServerCommandPending object. This destructor is
5601 now called after calling the pending callback or if error occurs
5602 immediately. If error occurs the actual pending callback won't
5603 be called at all - only the destructor. The destructor may be
5604 NULL if destructor is not needed.
5606 All this applies for client library code as well. Similar
5607 changes were made there as well for the pending commands.
5609 In the client, the application must now allocate the
5610 SilcClientCommandContext with the silc_client_command_alloc
5613 * Added reference counter to the SilcServerCommandContext. Added
5614 function silc_server_command_alloc and silc_server_command_dup
5617 Same type of functions added to the client library for the same
5620 * Removed the cmd_ident from IDListData away since it is now
5621 global for all connections. It is the command identifier used
5622 in command sending and with pending commands. The affected file
5625 * Added reference counter to the SilcSocketConnection objecet to
5626 indicate the usage count of the object. The object won't be
5627 freed untill the reference counter hits zero. Currently only
5628 server uses this, and client ignores it. The client must be
5629 set to use this too later. The affected files are
5630 lib/silccore/silcsockconn.[ch]. Added also the function
5631 silc_socket_dup to increase the reference counter.
5633 This was mainly added because it is possible that the socket
5634 is removed underneath of pending command or other async
5635 operation. Now it won't be free'd and proper DISCONNECTING
5636 flags, etc. can be set to avoid sending data to connection that
5637 is not valid anymore.
5639 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5640 the connection. After that it sets SILC_SET_DISCONNECTED.
5641 It is, however, possible that the socket data is not still freed.
5642 The silc_server_packet_process now checks that data is not
5643 read or written to connection that is DISCONNECTED. The socket
5644 get's freed when the reference counter hits zero.
5646 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Changed the client operation API: channel_message operation's
5649 `sender' is now the client entry of the sender, not the nickname
5650 and the `channel' is the channel entry, not the channel name.
5652 In the private_message operation the `sender' is now also the
5653 client entry of the sender not the nickname.
5655 Affected file is lib/silcclient/ops.h and all applications
5656 using the client operations.
5658 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Moved the calling of ops->connect() from connect_to_server_final
5661 into receive_new_id functin since that is the point when the
5662 client is actually allowed to send traffic to network. The
5663 affected file is lib/silcclient/client.c.
5665 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5668 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5669 (if needs broadcasting) instead of broadcasting the packets one
5670 by one which would make a burst in the network traffic.
5672 * Added `broadcast' argument to the functions in silcd/server.[ch]
5673 silc_server_create_new_channel[_with_id] to indicate whether
5674 to send New Channel packet to primary router.
5676 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Added new function into the silcd/server.[ch] files:
5679 silc_server_create_new_channel_with_id to create new channel with
5680 already existing Channel ID.
5682 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5683 lib/silccore/silcpacket.h. This packet is used t send list of
5684 Set Mode payloads inside one packet. Server uses this to set
5685 the modes for the channels and clients on those channels, that it
5686 announced to the router when it connected to it. The protocol
5687 specification has been updated accordingly.
5689 * The silc_server_new_channel did not handle the packet coming
5690 from normal server as it normally does not send that. However,
5691 when it announces its channels it does send it. Implemented
5692 the support for that.
5694 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5695 into the file lib/silccore/id.h.
5697 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Fixed memory leaks in the functions silc_idlist_del_client,
5700 silc_idlist_del_channel and silc_idlist_del_server in the file
5701 silcd/idlist.c. All of those leaked like a sieve.
5703 * Fixed some small memory leaks in the client's function
5704 silc_client_notify_by_server.
5706 * Added functions into silcd/server.c: silc_server_announce_clients,
5707 silc_server_announce_channels and silc_server_announce_server.
5708 These functions are used by normal and router server to announce
5709 to its primary router about clients, channels and servers (when
5710 router) that we own. This is done after we've connected to the
5713 These functions effectively implements the following packet types:
5714 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5715 and SILC_PACKET_NEW_ID_LIST.
5717 * Added new functions into the silcd/packet_receive.[ch]:
5718 silc_server_new_id_list, silc_server_new_channel_list and
5719 silc_server_new_channel_user_list to handle the incoming
5720 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5722 * Added support of changing Channel ID in the function
5723 silc_server_replace_id. If the server that announces a channel
5724 to the router already exists in the router (with same name but
5725 with different Channel ID), router is responsible to send
5726 Replace ID packet to the server and force the server to change
5727 the Channel ID to the one router has.
5729 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5730 client that the Channel ID has been changed by the router. The
5731 normal server sends this to the client. Client must start using
5732 the new Channel ID as the channel's ID.
5734 Implemented handling of this new type into lib/silcclient/client.c
5735 into the function silc_client_notify_by_server.
5737 * Added new function silc_idlist_replace_channel_id into the files
5738 silcd/idlist.[ch] to replace the Channel ID.
5740 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Call silc_server_command_identify_check always when processing
5743 the IDENTIFY command in silcd/command.c
5745 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5748 send keepalive packets. The packet can be sent by clients,
5749 servers and routers.
5751 Added function silc_socket_set_heartbeat into the file
5752 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5753 If not set, the heartbeat is not performed. The actual
5754 heartbeat is implemented in the low level socket connection
5755 library. However, application is responsible of actually
5758 Added silc_server_send_heartbeat to send the actual heartbeat
5759 packet into silcd/packet_send.[ch]. Server now performs
5760 keepalive with all connections.
5762 * Added silc_task_get_first function into lib/silcutil/silctask.c
5763 to return the timeout task with shortest timeout. There was a bug
5764 in task unregistration that caused problems. TODO has been
5765 updated to include that task system must be rewritten.
5767 * The client library will now resolve the client information when
5768 receiving JOIN notify from server for client that we know but
5769 have incomplete information.
5771 * Rewrote parts of silc_server_remove_from_channels and
5772 silc_server_remove_from_one_channel as they did not remove the
5773 channel in some circumstances even though they should've.
5775 * Encryption problem encountered in server:
5777 The LEAVE command used to send the Channel Key packet to the
5778 router immediately after generating it. However, the code
5779 had earlier sent Remove Channel user packet but not immediately,
5780 ie. it was put to queue. The order of packets in the router
5781 was that Channel Key packet was first and Remove Channel User
5782 packet was second, even though they were encrypted in the
5783 reverse order. For this reason, MAC check failed. Now, this
5784 is fixed by not sending the Channel Key packet immediately but
5785 putting it to queue. However, this is more fundamental problem:
5786 packets that are in queue should actually not be encrypted
5787 because packets that are sent immediately gets encrypted
5788 actually with wrong IV (and thus MAC check fails). So, packets
5789 that are in queue should be encrypted when they are sent to
5790 the wire and not when they put to the queue.
5792 However, the problem is that the current system has not been
5793 designed to work that way. Instead, the packet is encrypted
5794 as soon as possible and left to the queue. The queue is then
5795 just purged into wire. There won't be any fixes for this
5796 any time soon. So, the current semantic for packet sending
5799 o If you send packet to remote host and do not force the send
5800 (the packet will be in queue) then all subsequent packets to the
5801 same remote host must also be put to the queue. Only after the
5802 queue has been purged is it safe again to force the packet
5805 o If you send all packets immediately then it safe to send
5806 any of subsequent packets through the queue, however, after
5807 the first packet is put to queue then any subsequent packets
5808 must also be put to the queue.
5810 Follow these rules and everything works fine.
5812 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Added new function silc_server_remove_clients_by_server to
5815 remove all client entries from ID list when the server connection
5816 is lost. In this case it is also important to invalidate all
5817 client entires as they hold the invalid server entry. This
5818 fixes fatal bug when server has lost connection and will reconnect
5821 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5823 * Made some sanity checks to silc_server_daemonise like to check
5824 whether the requested user and group actually exists.
5826 * Added sanity check to SKE's silc_ske_responder_finish to check
5827 that the public and private key actually is valid.
5829 * Invalidate the client's nickname when receiving Replace ID
5830 packet and the Client ID is being replaced. This means that the
5831 server will query the nickname if someone needs it (client)
5834 * Sort the ID Cache in client library when the ID Cache data
5835 has changed (needs sorting).
5837 * Do not allow for SILC client to create several connections to
5838 several servers. The client does not support windows right now
5839 and generating multiple connections causes weird behaviour.
5841 Irssi-silc client does support windows and can handle several
5842 connections without problems, see: www.irssi.org and SILC plugin.
5844 * Fixed some places where client was added to the IDList. The
5845 rule of thumb is following (in order to get everything right):
5846 If the client is directly connected local client then the
5847 `connection' argument must be set and `router' argument must be
5848 NULL to silc_idlist_add_client function. If the client is not
5849 directly connected client then the `router' argument must
5850 bet set and the `connection' argument must be NULL to the
5851 silc_idlist_add_client function.
5853 * The funtion silc_server_packet_send_local_channel actually did
5854 not check whether the client was locally connected or not. It
5855 does that now. Fixed a bug related to LEAVE command.
5857 * Fixed Remove Channel User payload parsing bug in server's
5858 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5860 * The server's silc_server_save_channel_key now checks also the
5861 global ID list for the channel as it might not be in the local
5862 list. Fixed a bug related to LEAVE command.
5864 * Is this the end of the [<unknown>] buglet that has been lurking
5865 around for a long time? A little for loop fix in server's
5866 silc_server_command_whois_parse that is used by both IDENTIFY
5867 and WHOIS command. At least, this was a clear bug and a cause
5868 of one type of [<unknown>] buglet.
5870 * WHOIS and IDENTIFY commands call the function
5871 silc_server_command_[whois/identify]_check function even if
5872 we are not router server.
5874 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5876 * Added --with-gmp configuration option. If set the GMP
5877 is always compiled in the SILC source tree. If not set then
5878 it is checked whether the system has the GMP3 installed. If
5879 it has then the GMP won't be compiled (the system's headers
5880 and library is used), if it doesn't have it then the GMP is
5881 compiled in the SILC source tree.
5883 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Changed RSA private exponent generation to what PKCS #1
5886 suggests. We try to find the smallest possible d by doing
5887 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5888 not security fix but optimization.
5890 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added new config entry [Identity] to fork the server and run
5893 it as specific user and group. A patch from Bostik.
5895 * Imported Dotconf configuration library into lib/dotconf.
5896 This will be used to create the SILC configuration files later.
5897 It will appear in the distsribution after this commit.
5899 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * A big code auditing weekend happening. Auditing code for
5902 obvious mistakes, bugs and errors. Also, removing any code
5905 Removed files for being obsolete:
5907 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5908 inline in the file lib/silcutil/silcbuffer.h)
5910 o lib/silcutil/silcbufutil.c (the header has inline versions)
5912 Changed code to fix possible error conditions:
5914 o The buffer formatting routines now check that the destination
5915 buffer really has enough space to add the data. This applies for
5916 both buffer formatting and unformatting
5917 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5918 unformatting was changed to accomodate following rules:
5919 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5920 sent to the function while XXX_*STRING will not allocate or copy
5921 the data into the buffer. Instead it sets the pointer from the
5922 buffer into the pointer sent as argument (XXX_*STRING used to
5923 require that the pointer must be allocated already). This change
5924 makes this whole thing a bit more consistent and more optimized
5925 (note that the data returned in the unformatting with XXX_*STRING
5926 must not be freed now). The routines return now -1 on error.
5928 o Tried to find all code that use buffer_format and buffer_unformat
5929 and added return value checking to prevent formatting and
5930 especially unformatting errors and possible subsequent fatal
5933 o Changed ske->x and ske->KEY to mallocated pointers in
5934 lib/silcske/silcske.h. Fixed possible data and memory leak.
5936 o Added return value checking to all *_parse* functions. Fixed
5937 many memory leaks as well.
5939 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5940 so that buffer overflows would not happen. All code now also
5941 checks the return value as it can fail.
5943 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Added reconnection support to server if the normal server looses
5946 its connection to the router (for example if router is rebooted).
5947 The server performs normal reconnection strategy implemented
5948 to the server. Affected file silcd/server.c.
5950 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Added new packet type SILC_PACKET_SET_MODE that is used to
5953 distribute the information about changed modes (for clients,
5954 channels and clients channel modes) to all routers in the
5955 network. Updated the protocol specification accordingly.
5957 Added functions into silcd/packet_send.c and
5958 silcd/packet_receive.c: silc_server_send_set_mode,
5959 silc_server_set_mode.
5961 Added new files silcmode.[ch] into lib/silccore that implements
5962 the encoding and decoding of Set Mode Payload. Added new type
5963 SilcSetModePayload. Moved the definitions of different modes
5964 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5966 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Oops, a little mistake in server's connection authentication
5969 protocol. The protocol is not ended with FAILURE but with
5970 SUCCESS if the authentication is Ok. :) Affected file is
5973 * Implemented NICK_CHANGE notify handling in server in the file
5974 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5975 the local clients on the channel. After the changing nickname
5976 in router environment snhould work and the [<unknown>] nickname
5977 should appear no more.
5979 The silc_server_replace_id function that receives the Replace ID
5980 payload now sends the NICK_CHANGE notify type also in the file
5981 silcd/packet_receive.c
5983 * Changed WHOIS and IDENTIFY command to support the maximum amount
5984 of arguments defined in protocol specs (3328 arguments). This
5985 fixed a bug that caused problems when there were more than three
5988 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added extra parameter, command identifier, to the
5991 silc_client_send_command so that explicit command identifier
5994 Changed that ID list routines uses specific command identifier
5995 when sending WHOIS/IDENTIFY requests to the server so that they
5996 can be identified when the reply comes back.
5998 Affected files lib/silcclient/command.[ch],
5999 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6001 * Added `sender' argument to silc_server_packet_send_to_channel
6002 to indicaet the sender who originally sent the packet to us
6003 that we are now re-sending. Ignored if NULL. Affected file
6004 silcd/packet_send.[ch].
6006 * Added some server statistics support in silcd/server_internal.h
6007 SilcServerStatistics structure and around the server code. Also
6008 send some nice statistics information when client is connecting
6011 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Fixed channel ID decoding in server's JOIN command reply in
6014 silcd/command_reply.c
6016 * Fixed braodcasting of replace ID payload to not to send it if
6017 we are standalone server in silcd/packet_receive.c.
6019 * Fixed all channel message sending routines to not to send
6020 packets to clients that has router set, since they are routed
6021 separately in the same function earlier. Affects file
6022 silcd/packet_send.c and all channel packet sending functions.
6024 * In USERS reply, res_argv[i] are not allocated, the table
6025 is allocated. Thus changed that free the table, not its
6028 * In server's whois_check and identify_check if the client is
6029 locally connected do not send any WHOIS commands - they are not
6032 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Fixed some minor bugs in client when sending WHOIS command. The
6035 arguments was in wrong order.
6037 * Removed statis function add_to_channel from server in
6038 silcd/command.c that was previously used with the joining but
6041 * Tested USERS command in router environment successfully with two
6042 routers, two servers and two clients.
6044 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Reorganized the USERS command and command reply in client library
6047 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6048 When the command is given by user we register a pending command
6049 callback that will reprocess the command after the reply has been
6050 received from the server. When reprocessing the packet we then
6051 display the information. Thus, the USERS information is displayed
6052 now in the command callback instead of in the command reply
6053 callback. The processing of the command is same as previously
6054 when server has sent the command reply in the JOINing process.
6056 * Added to USERS command in silcd/command_reply.c to join the client,
6057 we didn't use to know about, to the channel after we've created
6058 a client entry for it. Also, for clienet we did know already still
6059 check whether it is on the channel or not and add it if not.
6061 * Removed silc_server_command_join_notify as the function and its
6064 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Changed the client's pending command handling to the same as the
6067 server's pending command handling. It is also now possible to
6068 execute command reply functions from other command reply
6069 function as the function callbacks for commands and command
6070 replies are one and same. The pending commands are not static
6071 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6072 in client connection context. Thus, pending commands are server
6073 connection specific as it is convenient.
6075 Changed the function silc_client_command_pending and
6076 silc_client_command_pending_del and added new function
6077 silc_client_command_pending_check. Removed the
6078 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6081 * Added cmd_ident, current command identifier, to the client
6082 connection context in lib/silcclient/client.h to keep track on
6083 command identifiers used in command sending. Client's command reply
6084 function handling now supports the mandatory command identifiers.
6086 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6087 funtions in client to fully support pending command callbacks.
6089 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6090 as one of the arguments to the application in the command reply
6093 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6094 before first releasing SILC but came back. Now it is removed again
6095 and should come back nomore. The FORWARDED flag was used only
6096 by the JOINing procedure by forwarding the command packet to router.
6097 Now, the JOINing procedure has been changed to more generic (due
6098 to various router environment issues) and FORWARDED is not needed
6099 anymore for anything. The protocol specification is yet to be
6102 Now, removed silc_server_packet_forward from server and the flag
6103 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6105 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Renamed NAMES command to USERS command. The NAMES was named that
6108 due to historical reasons. Now it is renamed. Also, rewrote
6109 parts of the USERS command. The nickname list is not sent anymore
6110 by the server. Only Client ID and mode lists are sent in the USERS
6111 command. Changed this also to the protocol specification.
6113 The client now resolves the names and stuff after it receives
6114 the USERS list from the server when joining to the channel.
6116 * WHOIS and IDENTIFY commands has been changed to support multiple
6117 Client ID's per command. One can now search for multiple users
6118 in the network by sending only one WHOIS or IDENTIFY command.
6119 Changed the code and the protocol specifications.
6121 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6122 uses silc_server_command_whois_parse to parse the request. */
6124 * If normal server, do not parse the WHOIS and IDENTIFY requests
6125 before sending it to the router. Saves some time.
6127 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Fixed JOIN command on client library. Wrong number of arguments
6130 used to crash the client.
6132 * Added silc_server_channel_has_global function to check whether
6133 channel has global users or not.
6135 * Added silc_server_channel_has_local function to check whether channel
6136 has locally connected clients on the channel.
6138 * The silc_server_remove_from_one_channel now checks whether the
6139 channel has global users or not after given client was removed from
6140 the channel. It also checks whether the channel has local clients
6141 on the channel anymore. If it does not have then the channel entry
6142 is removed as it is not needed anymore.
6144 * The silc_server_notify now checks on JOIN notify whether the joining
6145 client is one of locally connected or global. If it is global then
6146 the channel has now global users on the channel and that is marked
6147 to the channel entry. Also, it now saves the global client to
6148 global list who is joining and JOINs it to the channel. This is
6149 for normal server, that is.
6151 Changed silc_server_send_notify_on_channel,
6152 silc_server_packet_relay_to_channel and
6153 silc_server_packet_send_to_channel check if we are normal server
6154 and client has router set (ie. global client) do not send the
6155 message to that client, as it is already routed to our router.
6157 * Implemented LEAVE notify type handling in silc_server_notify
6160 * Tested LEAVE command in router environment successfully. Tested
6161 with two routers, two servers and two clients.
6165 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6167 * Implemented SIGNOFF notify type handling in silc_server_notify
6170 * silc_server_remove_id now removes the client entry from all channels
6171 it has joined and thusly sends SIGNOFF notify type.
6173 * Rewrote the NAMES list generation in server by removing two excess
6174 loops. The lists are created now inside one loop.
6176 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * silc_server_remove_channel_user checks now also global list
6179 for channel and client.
6181 * silc_server_new_channel_user checks now both local and global
6182 list for channel and client. Fixed a bug in client id decoding.
6183 Used to decode wrong buffer.
6185 * silc_server_channel_message checks now both local and global
6186 list for channel entry.
6188 * Tested channel joining (hence JOIN) in router environment
6189 successfully. Tested with two routers, two servers and two
6192 * Tested channel message sending in router environment successfully.
6194 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Added silc_server_save_channel_key into server.[ch] to save the
6197 received channel key in Channel Key payload processing. It is
6198 also used in JOIN command reply handling.
6200 Equivalent function silc_client_save_channel_key added into
6201 client.[ch] into client library.
6203 * Changed JOIN command reply to send information whether the channel
6204 was created or not (is existing already) and the channel key
6205 payload. Changed protocol specs accordingly.
6207 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6208 the request was sent by ID and not by nickname. Crashed on
6211 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6214 now correctly save the received data.
6216 * silc_server_free_sock_user_data now notifies routers in the
6217 network about entities leaving the network.
6219 At the same time implemented functions silc_server_remove_id
6220 and silc_server_send_remove_id to receive and send REMOVE_ID
6221 packets. The packet is used to notify routers in the network
6222 about leaving entities. The ID removed will become invalid in
6225 * Added function silc_idlist_del_server into server. Removes and
6226 free's server entry from ID list.
6228 * silc_server_private_message function now checks, if we are router,
6229 that the destination ID really is valid ID, naturally.
6231 * In router when NEW_ID packet is received (for new client) the
6232 hash of the Client ID is saved in the ID Cache but the
6233 client->nickname is set to NULL, instead of putting the hash
6236 IDENTIFY command now also checks that client->nickname must be
6237 valid. If it is not if will request the data from the server who
6238 owns the client. Added new function
6239 silc_server_command_identify_check.
6241 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6242 to set the command to already allocated Command Payload.
6244 * Tested private message sending in router environment with two
6245 routers, two servers and two clients. Fixed minor bugs and now
6248 * Fixed segfault from client's NAMES command. Used to crash if
6251 * Forwarded packets must not be routed even if it is not destined
6252 to the receiver. Changed server code comply with this.
6254 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Added `require_reverse_mapping' boolean value to ServerParams
6257 structure. If TRUE (not default) the server will require that
6258 the connecting host has fully qualified domain name.
6260 If the reverse mapping is not required and hostname could not be
6261 found the IP address is used as hostname.
6263 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Implemented version string checking to both client and server.
6266 The check is incomplete currently due to the abnormal version
6267 strings used in development version of SILC.
6269 * Changed all command functions in server to use the new
6272 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Changed char *data to unsigned char *data in ID Cache system to
6275 support binary data as ID Cache data. Changed code to support
6276 binary data in lib/silccore/idcache.c.
6278 * Renamed silc_server_packet_relay_command_reply to
6279 silc_server_command_reply as it is normal packet receiving
6280 function. Rewrote the function to accept command replys for
6281 servers and not only for clients.
6283 * Mark remote router always as registered server if we are connecting
6284 to it. Otherwise, commands sent by the router to us are ignored.
6286 * All ID List find routines now returns the ID Cache Entry pointer
6287 as well if requested.
6289 * WHOIS command works now in router environment, tested with two
6290 routers, two servers and two clients.
6292 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6293 in router environment (as it is almost equivalent to WHOIS) but
6294 hasn't been tested thoroughly. Added new functions:
6296 silc_server_command_identify_parse
6297 silc_server_command_identify_send_reply
6298 silc_server_command_identify_from_client
6299 silc_server_command_identify_from_server
6301 * Disabled route cache adding because adding two different ID's with
6302 same IP replaces the old cache entry thus giving wrong route.
6303 The entry->router->connection is always the fastest route anyway
6304 so route cache may not be needed. Of course, new routes maybe
6305 established after receiving the ID when the entry->router->connection
6306 might not be anymore the most optimal.
6308 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Add route cache for received ID for fast routing.
6312 * Added silc_server_packet_route to route received packet on router
6313 that is not destined to us.
6315 * Renamed silc_server_get_route to silc_server_route_get.
6317 * Added id_string and id_string_len fields into SilcServer to
6318 include encoded ServerID for fast comparing without excess
6319 encoding of the ID's.
6321 * Cleaned up WHOIS command on server side. Added following static
6324 silc_server_command_whois_parse
6325 silc_server_command_whois_check
6326 silc_server_command_whois_send_reply
6327 silc_server_command_whois_from_client
6328 silc_server_command_whois_from_server
6330 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6331 arguments in command replies. All command functions should be
6332 updated to use this macro.
6334 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Minor typo fixes on command reply handling on server.
6338 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Added silc_server_command_add_to_channel internal routine to add
6341 the client to the channel after router has created the channel and
6342 sent command reply to the server.
6344 * Added generic silc_server_send_command to send any command from
6347 * Use static buffer with ID rendering instead of duplicating data.
6349 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Fixed a channel user mode bug when joining to a channel server gave
6352 everybody channel founder rights, oops.
6354 * We mark ourselves as the router of the incoming server connection
6355 if we are router ourselves. This way we can check in some packet
6356 sending functions whether it is locally connected server. For
6357 incoming router connections we put NULL.
6359 * For router sending packets locally means now always sending the
6360 packet cell wide; to local clients and local servers. For normal
6361 server sending packet locally means sending it to only local
6364 * Fixed the JOIN command to really work in router environment. If the
6365 channel is created it is always created by the router. Router is
6366 also responsible of making the initial joining to the channel,
6367 sending JOIN notify to the sending server and distributing
6368 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6369 does not exist server doesn't do anything else but forward the
6370 command to the router which performs everything.
6372 * Added silc_server_send_channel_key function to send the Channel Key
6375 * Added silc_server_create_channel_key to create new channel key. The
6376 channel key is now re-generated everytime someone joins or leaves
6377 a channel, as protocol dictates. Note: channel->key_len is the
6380 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6383 packet_receive.[ch] to separate packet sending and receiving
6384 routines. The server.[ch] now includes everything else including
6385 actual packet processing (writing and reading data) and other
6388 Renamed silc_server_private_message_send_internal to
6389 silc_server_send_private_message. The routine is still though
6390 used only to relay private messages as server does not send
6391 private messages itself.
6393 Renamed silc_server_new_channel to silc_server_create_new_channel
6394 and added new function sicl_server_new_channel that handles the
6395 incoming New Channel packet. Added also new sending function
6396 silc_server_send_new_channel to send New Channel Payload.
6398 * Added new function silc_server_notify to process incoming notify
6399 packet to the server/router. Server may then relay the notify
6400 to clients if needed.
6402 * Added new function silc_server_new_channel_user to process incoming
6403 New Channel User packet. Router will redistribute the packet and
6404 send JOIN notify to its local clients and locally connected servers
6405 if needed. Normal server will send JOIN notify to its local client
6406 on same channel when received this packet. Added also corresponding
6407 sending function silc_server_send_new_channel_user to sent the
6410 * Added boolean route argument to send_notif_to_channel and
6411 packet_send_to_channel functions to attempt to route the packet
6412 if it is TRUE and send only locally if it is FALSE.
6414 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * silc_server_replace_id now broadcasts the received replace ID
6417 packet if it is not broadcast packet already. The router must
6418 broadcast to inform other routers about changed ID.
6420 * Added backpointer to server's router into SilcServer context in
6421 silcd/server_internal.h.
6423 * Fixed silc_server_packet_broadcast to send correct broadcast
6426 * The channel key is now distributed to the local client as soon
6427 as it is received from the router (in router environment) so that
6428 no other packet may be sent for the channel until client has
6431 * silc_server_remove_channel_user now broadcasts the received
6432 Remove Channel User packet if it is not broadcast packet already.
6433 The router must broadcast to inform other routers about removed
6436 * Added users field into SilcPacketContext that is a reference count
6437 of the context. One can increase the reference count by calling
6438 silc_packet_context_dup which is now changed to just increase the
6439 reference count instead of duplicating the data. The reference
6440 count is decresed by calling silc_packet_context_free that will
6441 free the data after the reference count hits zero.
6443 For now on the packet context and everything allocated into it
6444 (including the raw packet from network) must be freed by calling
6445 the new silc_packet_context_free function. Added also new function
6446 silc_packet_context_alloc that must be used now to allocate the
6447 context. This also means that if a routine is asynchronous from
6448 silc_[client/server]_packet_parse_type the packet context must
6449 be duplicated by calling silc_packet_context_dup. Otherwise it
6450 gets free'd after silc_[client/server]_packet_parse_type returns.
6451 Also, one must remember that if packet is duplicated then its
6452 reference count must be decresed by calling the free function as
6453 many times as it was duplicated.
6455 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6456 from both client and server.
6458 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Made joining to a channel working in router environment.
6462 * Cleaned up JOIN command on server side and create function
6463 silc_server_command_join_channel internal routine to make the
6466 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Changed silc_command_pending list to SilcDList. Also, added
6469 `ident' field to SilcServerCommandPending structure to identify
6470 the reply and to call correct callback.
6472 Added silc_server_command_pending_check function to replace the
6473 corresnponding macro. The silc_command_pending list is not
6476 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6477 to set identifier to previously allocated Command Payload. It
6478 is used to set identifier for command when resending Command
6481 * Added silc_command_payload_encode_payload to encode Command
6482 Payload buffer from SilcCommandPayload structure.
6484 * Added silc_argument_payload_encode_payload to encode Argument
6485 payload buffer from SilcArgumentPayload structure.
6487 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Changed WHOIS command to support router connection on server side.
6490 The whois request is always sent to router unless the server is
6491 standalone server. After server has received the reply from the
6492 router will it send the reply to the client.
6494 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6495 broadcast received broadcast packet. The function is used only
6496 by router. The broadcast packet is always sent to the router's
6499 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6500 render given ID to printable string, for log files for example.
6502 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Made basic router to router connections working. At least they
6505 can now connect to each other but nothing really works the way
6506 they are supposed - yet.
6508 * Added new initiator token to RouterConnection configuration
6509 file in silcd/serverconfig.[ch]. It is used to tell whether we
6510 are the initiator to the remote router or whether we'll expect
6511 the other end to connect.
6513 * Moved registering of listener task to silc_server_init, hence
6514 the server starts listenning as soon as it is run, even if it
6515 does not have connections to other routers. Let's see how well
6518 * Changed default connection retry timeouts for more suitable in
6521 * Removed cipher and such arguments from silc_idlist_add_client
6522 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6523 Added new function silc_idlist_add_data to add the keys and stuff
6526 * Added SilcIDListData structure and added it to SilcClientEntry
6527 and SilcServerEntry as their first field in the structure. This
6528 way we can explicitly cast the ID entries to the SilcIDListData
6529 structure and get common data for the entries. In past, we had
6530 to first check what type of connection it is and then cast it to
6531 correct ID entry type. Now, we can directly cast the opaque
6532 pointer to the SilcIDListData (no matter what ID entry it actually
6533 is) and get the data needed.
6535 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6538 in some circumstances even if threre were timeout tasks, though not
6539 IO tasks, but tasks anyway. Now fixed.
6541 * Defined SilcServerConnection structure to hold connection specific
6542 stuff about directly connected servers and routers. The definition
6543 is currently in silcd/server_internal.h. I thought about having
6544 a bit more important role fro this struct but for now it is used
6545 only when connecting to other server (or router actually).
6547 * Added connecting retry support in server when connecting to
6548 router(s). The retry feature implement exponential backoff
6549 algorithm. Also, added SilcServerParams structure to hold default
6550 parameters for server. For now, it include these retry settings
6551 and are hard coded. After server is moded to be as Silc Server
6552 Library this structure will be more important.
6554 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Changed client librarys channel->clients table to SilcList and
6557 changed code accordingly.
6559 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Changed client's channel table to SilcList and changed code
6562 accordingly. Also changed SilcChannelClientEntry to include back-
6563 pointer to the channel so that client entry can use that structure
6564 as list as well and we have fast cross-reference to the channel.
6565 This change dramatically decreased the complexity of channel
6566 handling with client entry and vice versa (removed one extra
6567 loop when searching for channel entry from many functions).
6569 * Changed server->sim from table to SilcDList and changed code
6572 * NAMES command can now be used from user interface. It will show
6573 the user list on the channel, neatly.
6575 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6576 Code now saves realname of the user if it becomes available.
6578 * Renamed configure.in to configure.in.pre and made ./prepare
6579 script to automatically add correct version string to
6580 configure.in which it creates from configure.in.pre.
6582 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * NAMES command reply now shows users mode with the nickname when
6587 * Moved silc_client_ch[u]mode[_char] functions from
6588 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6589 place sucks, they are utility functions and should be in some
6592 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6594 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6597 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Added TRQ (efficient deque and list library) into lib/trq. This is
6602 a very good list library that is currently used in the SILC. Defined
6603 SilcList API over the library because I didn't like the API very
6604 much. See lib/trq/silclist.h for the API and examples of how to
6605 use the API. Fixed various places in the code to use the new
6606 SilcList API. The SilcList is meant for lists that has a structure
6607 already defined as a list. It is not suitable to add just some
6608 context to the list (in TRQ, the context is the list actually).
6610 So, I defined SilcDList that can be used for the purpose where
6611 predefined list structure does not exit. This can be used as
6612 such list. Now some context just can be added to the SilcDList.
6613 Currently this list is not used in the SILC just yet, though there
6614 are a lot places where this can replace dynamically allocated
6615 tables and I will fix these places, later, to use SilcDList.
6616 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6617 and use TRQ internally).
6619 Also fixed some annoying warning messages that the original TRQ
6620 code generated. Also minor changes to TRQ's Makefile.in.
6622 * Added support for querying by Client ID to both WHOIS and
6623 IDENTIFY commands into server, as required by the protocol.
6625 * Removed method function pointers from SilcBuffer structure. They
6626 weren't used to anything and just increased the context size for
6627 no good reason. This change also made silc_buffer_alloc and
6628 silc_buffer_free functions inline functions.
6630 * Disabled command flooding detection support until it's fixed so
6631 that it accepts commands in but does not execute them more than once
6634 * Added silc_net_localhost(), to return local hostname, into
6635 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6636 that must be initialized before calling silc_client_init.
6638 * Added new function: silc_server_send_notify_on_channels to send
6639 notify messages to all channels client has joined. It is assured
6640 that the message is sent only once per client.
6642 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6643 lib/silcutil/silcutil.[ch] as silc_format function. The new
6644 function is generic and is used by server as well, not only by
6645 the logging routines.
6647 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6648 the provided version string was not acceptable. Added new function:
6649 silc_ske_check_version into lib/silcske/silcske.h. The function
6650 must be implemented by the application (client or server) and it
6651 does not reside in the SKE library. The function checks the version
6652 string remote end sent.
6654 * Added back pointers (to opaque context and to SilcSocketConnection)
6655 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6657 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6658 duplicate packet context structure.
6660 * Changed `notify' client operation to send same arguments as client
6661 receives from server except for ID's. ID's are mapped to correct
6662 ID entry and that is returned. Also, if channel entry is not sent
6663 by server but the notify is for channel the channel entry is sent
6664 to application (otherwise application doesn't know that it is for
6665 channel (library gets it from packet's Destination ID)).
6667 * Added silc_client_remove_from_channels into client library to
6668 remove a client from all channels it has joined to. Used when
6669 received SIGNOFF notify from server. Added also new function
6670 silc_client_replace_from_channels to replace old ID entry with
6671 new ID entry on all channels. Used when received NICK_CHANGE
6674 * Fixed ID Cache list handling in silc_idlist_get_client in
6675 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6676 to get (or query) client by ID.
6678 * Updated TODO list.
6680 * Added connection authentication status message defined by the
6681 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6682 support for these into the code in client and server side.
6684 * Added generic function silc_client_send_command to send any command
6685 with variable argument list. Application should use this function
6686 to send commands if the command functions provided by the library
6687 does not suite for the application's user interface needs.
6689 * Added new `failure' client operation. Application is notified about
6690 received failure packet if client is executing a protocol. In this
6691 case the protocol's execution has failed.
6693 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6694 is required by the protocol.
6696 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6697 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6700 * Added status flag to SilcSKE object to indicate realtime status
6701 of the SKE protocol.
6703 * Application receives now exactly same command reply arguments as
6704 the library receives from server. However, if ID is received the
6705 corresponding ID entry is returned to the application (eg. Client
6706 ID is mapped to correct SilcClientEntry entry and that is returned).
6707 Changed command_reply client operation due to this change.
6709 * Changed all ID's in commands and in command replys as ID Payloads.
6710 Change affected both client and server side codes.
6712 All ID's sent in SILC network (with execption of ID's in SILC
6713 Packet header) are sent in ID Payload to support variable length
6716 * Server now notifies nick changes and notifies all clients on
6717 the channels about the new nickname (about the new Client ID,
6720 * Implemented CMODE command to change channel modes. Supports all
6721 channel modes defined by the protocol specs except ban and invite
6722 lists. (Also, private channel key mode is supported but support for
6723 setting private channel key in client is missing, thus, this mode
6724 has no effect on client side (except that server requires that the
6725 client uses private channel key and normal channel traffic does not
6728 Also, invite mode works per se, but INVITE command does not work
6729 yet correctly, so you can set channel as invite only channel but
6730 inviting clients to the channel does not work (it is yet to be
6731 thought what's the best way to do it).
6733 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6734 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6735 Implemented CUMODE command to change user's mode on the channel.
6736 Supports all modes defined by the protocol specs.
6738 * Added NAMES command reply to return users modes on the channel.
6740 * Removed unnecessary and slow ciphers from lib/silccrypt.
6742 * Set SO_KEEPALIVE option to connection sockets by default.
6744 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6746 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6747 redefined the Notify Payload into protocol specs.
6749 * Added silc_id_payload_parse_id to get ID directly from raw
6752 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6755 accept searching by Client ID as well.
6757 * Added support for LEAVE and SIGNOFF notify types in client library.
6759 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6760 to parse ID Payload from raw data.
6762 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Added flags parameter into silc_ske_assemble_security_properties
6765 function in lib/silcske/silcske.[ch].
6767 * Changed notify client operation to fit better for notify messages
6768 sent by server. The notify payload received from server is now
6769 passed to the application (after parsing it to SilcNotifyPayload).
6770 It is application's responsibility to retrieve the arguments
6771 from the payload and show the message the way it wants. The message
6772 sent by server is implementation specific.
6774 * Changed public keys to comply with the protocol specification.
6775 Old public keys are not supported anymore and are not compatible.
6777 * Removed nickname from Channel Payload as the latest draft removed
6778 it. The client must resolve the nickname from the NAMES command
6779 reply received when it joined the channel.
6781 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6783 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Fixed some errors in protocol specification drafts.
6787 * Created lib/silccore/silcnotify.c to implement Notify Payload
6788 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6789 generic payloads described by protocol specifications. The file
6790 includes implementations for ID Payload and Argument Payload.
6792 * Changed Command Payload implementation to use the new Argument
6793 Payload. Changed command_xxxx_payload to command_payload_xxxx
6794 to comply with SILC coding conventions.
6796 * Added suppport for Argument Payload handling in Notify Payload
6797 implementation as protocol requires it. Added the new support
6798 into server and client lib as well.
6800 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Added support for multiple nicknames on same channel. [n] is
6803 added locally to the nickname if there are more than one same
6804 nicknames on the channel.
6806 * Server now sends all nicknames that matched WHOIS request.
6807 Client also shows the list received from server.
6809 * Added TOPIC command to client side. User can now set and show
6810 current topic on channel.
6812 * Added MOTD command to client and server. Also, server sends the
6813 motd when client connects to the server.
6815 * Changed version strings to comply ISO 8601.
6817 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Fixed protocol error handling in client library. It should now
6820 cope even if the SKE fails for some reason.
6822 * Made new protocol specification drafts for submitting to IETF.
6824 * Implemented TOPIC command to server in silcd/command.c.
6826 * Added two new notify types into lib/silccore/silcnotify.h:
6827 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6828 notify nickname change and topic setting/change on a channel.
6830 * API change of command_reply operation in client library. The
6831 application gets now the status type received from server as well.
6833 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6837 * Cras fixed and optimized the packet handling even further and
6838 it should work now. Minor change to the prototype of function
6839 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6841 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Added new function into lib/silcutil/silcschedule.[ch]:
6844 silc_schedule_with_fd to select() a specified fd. The function
6845 returns after timeout expires or data arrives or goes. The
6846 function is used by packet routines to wait that all data is
6847 received from network.
6849 * Fixed data reading from network in lib/silccore/silcpacket.c.
6850 The code now assures that all data is read from the fd and then
6851 continues packet processing. This was a bug fix since the code
6852 used to drop some data in some circumstances.
6854 * Added new function into lib/silcclient/client.[ch]:
6855 silc_client_start_key_exchange to start key exchange after
6856 connection has been established to server. The code internally
6857 now uses this funtion but its main purpose was to provide it
6858 for applications that perform their own connecting. After
6859 application has created a connection it merely calls this
6860 function to start the key exchange between client and server.
6861 The library takes care of everything else after that.
6863 Updated also lib/silcclient/README to explain the usage of
6866 * Do not send to application information that connection has
6867 been established. Application gets notified it by connect
6870 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Applied cras's patch to add silc_schedule_one function. The
6873 function runs scheduler once and returns.
6875 * Fixed the scheduler after cras messed it up. The timeout
6876 handling works now as it's supposed to work.
6878 * Added into lib/silccore/ silcnotify.h to include notify
6879 message types support. Changed silc_server_send_notify*
6880 functions, in server.[ch], to support those new notify types.
6881 Added the support for the notify types into client library,
6882 as well. Added new notify client operation into ops.h in
6885 * Changed silc_server_packet_send_to_channel to send normal
6886 packets instead of just channel message packets. The function
6887 is now used to send the notify packets to channels. It is not
6888 used to send channel message packets anymore, as server never
6891 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6892 va_arg()s as it seems to require it nowadays. I guess, if SILC
6893 is compiled with older va_arg() the new code should work anyway.
6895 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Splitted core library. Core library (lib/silccore) includes
6898 now only SILC protocol specific core (and common) components.
6899 Created new utility library (lib/silcutil) that includes more
6900 generic purpose stuff. The stuff for util library was taken
6901 from the old core library. This was minor and easy split.
6903 * Created SILC Client Library (lib/silcclient) that includes
6904 implementation of the SILC client without user interface. This
6905 was major move from silc/ directory. The code has been changed
6906 so that it is transparent towards the user interface. The
6907 silc/ directory includes now the same user interface as before
6908 and it uses the new client library. Read lib/silcclient/README.
6909 Basicly, the client library performs everything else related
6910 to SILC except user interface handling. Also, configuration
6911 files are considered to be part of user interface and library
6912 does not handle them.
6914 This change also changed a lot of structures, function naming etc.
6915 Most important change was that SilcClientWindow object was
6916 renamed to SilcClientConnection in the client library. Created
6917 also new file lib/silcclient/ops.h. Also added new files
6918 silc/local_command.[ch] and silc/client_ops.[ch].
6920 All these changes were made to make it easier for user interface
6921 designers to create what ever user interface for the SILC client
6924 It is also expected that the server will be moved to lib
6925 directory as well and SILC Server Library will be created;
6926 sometimes in the future.
6928 * Removed Local commands from lib/silccore/silccommand.h as
6929 they are application specific and new client library does not
6930 handle any of those anymore.
6932 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6933 old client implementation in silc/.
6935 * Added support for callback functions in SILC_LOG_* macros.
6936 Application can now set its own callbacks that will be called
6937 instead of using the default functions that will always print
6938 the debug messages to stderr (or stdout). Also, debugging can
6939 now be disabled by setting silc_debug to FALSE and re-enabled by
6940 setting it to TRUE. Note, that logging will still work even
6941 if debugging is disabled.
6943 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6944 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6945 silc_log_reset_debug_callbacks.
6947 * To enable debugging in silc client one must give now -d
6948 option on command line.
6950 * Changed silc_schedule_init to automatically allocate task queues
6951 if they are not allocated before calling it.
6953 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Added GMP 3.1 into math library.
6957 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6960 a channel in SILC network. The packet is used by servers and
6961 routers to notify other routers that user has left a channel.
6962 This little feature was missing until now. Added the feature
6963 to protocol specification as well.
6965 Added functions: silc_server_send_remove_channel_user and
6966 silc_server_remove_channel_user into server.[ch].
6968 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6969 lib/silccore/silcpacket.h. However, they are not implemented
6972 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Fixed joining to a channel and sending channel messages
6975 between server and router. The channel message sending should
6976 now work inside a cell.
6978 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Fixed the private message sending between server and router.
6981 The private message sending should now work inside a cell.
6983 * Added silc_server_replace_id into server.[ch] to replace
6984 existing ID in the SILC network.
6986 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6987 and silc_idlist_replace_server_id into idlist.[ch] in server.
6989 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6991 * Fixed the server to server connections. Server can again now
6992 connect to router. Router to router connections probably does
6995 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * Added dynamic protocol registering support. Now protocols can
6998 registered and unregistered on the fly. Patch by cras.
7000 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7002 * Added lib/contrib directory to hold routines that some platforms
7003 don't have but are needed by SILC.
7005 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7006 into lin/contrib to provide getopt() and getopt_long() for
7007 those who don't have it.
7009 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Added AWAY command to client. When away message is set and
7012 client receives a private message packet the client automatically
7013 replies to the sender with the away message.
7015 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7016 bug seemed to be the cause of recent problems when compiling
7019 * Added version detection support to SKE protocol specification
7020 and added the new changes to the SKE implementation as well.
7021 There were other minor changes in the SKE protocol as well.
7023 Many changes in lib/silcske/silcske.[ch] and in
7024 lib/silcske/payload.[ch].
7026 * Added ^U functionality, clear input line. Patch from cras.
7028 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7030 * Mainly small bugfixes on core library. Fixed some debugging
7031 logging and buffer overflow in silclog.c.
7033 * Updated config.sub and config.guess on the distribution tree.
7035 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * Added command lagging support in server. Client may execute
7038 commands now only once in two seconds.
7040 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Optimized packet reception. MAC computation and checking is now
7043 also more optimized. A lot previously duplicated code is now
7044 used as generic by both client and server.
7046 * Fixed key pair generation in clientutil.c
7048 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Added into lib/silccore/silcbufutil.[ch] new function;
7051 silc_buffer_realloc.
7053 * Moved generic packet sending/encryption functions to
7054 lib/silccore/silcpacket.[ch] from client and server. Some
7055 rewriting of the functions.
7057 * Moved all generic packet reception/decryption functions to
7058 lib/silccore/silcpacket.[ch] from client and server. The
7059 packet processing is now much cleaner in both client and server.
7060 These were major changes in both client and server.
7062 * Created many common functions in server to do packet sending.
7063 Previously code were duplicated a lot, this has been removed
7066 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Rewrote major parts of the ID cache system. Don't know
7069 whether it is better now or not but at least the API is more
7072 * Major rewrite on ID cache stuff on client because of the ID
7073 cache API changes. Added idlist.c to client.
7075 * Also major rewrite on ID cache stuff on server as well.
7076 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7077 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7078 in hand, instead they are all put into the ID cache system now.
7079 All server_idlist_* routines uses ID cache now instead of
7080 traversing its own lists (those lists does not exist anymore).
7081 SilcIDList though still exists. Also, SilcXXXEntry's are
7084 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7086 * Finally made the SKE implementation compliant to the protocol
7087 specification. All mp integers are now binary encoded as
7088 opposed being HEX encoded.
7090 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7093 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7094 functions: silc_[encode/decode]_pem. Also added function
7095 silc_encode_pem_file to PEM encode with newlines ('\n') for
7098 * SILC public keys are now encoded either PEM or binary. Same
7099 option is for private keys as well. By default private keys
7100 are binary encoded and public keys PEM encoded. Silly HEX
7101 encoding were removed.
7103 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7104 function to create fingerprints.
7106 * Fixed a bug in SHA1; does not change the original data anymore.
7108 * Partly implemented INFO command on client and server side.
7109 Fixed CLEAR command. Changes to SERVER command; show current
7110 server(s) when giving command without arguments. Added
7111 VERSION command to client.
7113 * Added check to server that unregistered connections cannot
7114 execute commands (unless it is specificly allowed).
7116 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Fixed screen refresh.
7120 * Fixed channel joining bug from client. On some circumstances
7121 client tried to join to a channel it had already joined.
7123 * Added public key verification process into client's protocol.c.
7124 The client now verifies the public key from user and saves
7125 it into ~./silc/serverkeys/ directory.
7127 Added into: clientutil.[ch]: silc_client_verify_server_key.
7129 * Changed SKE protocol's silc_ske_initiator_finish function
7130 to accept callback function that verifies the received public
7131 key. Removed old silc_ske_verify_public_key function.
7133 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7136 silc_pkcs_private_key[_data]_set.
7138 * Made the password and public authentication more cleaner in
7139 server's protocol.c.
7141 * Removed historic and obsolete protocol `channel_auth' from
7142 both client and server.
7144 * Removed wrong way of sending command status messages from
7145 server to client in server's command.c. The old way violated
7146 protocol specification.
7148 Changes to silccore/silccommand.[ch]: removed
7149 silc_command_encode_status_payload -> not needed anymore,
7150 changed silc_command_encode_payload_va to accept extra
7151 argument on variable argument list. The argument type must
7152 now be provided to the function. Also, added new function:
7153 silc_command_encode_reply_payload_va which is same as
7154 normal command_encode_payload_va except command status type
7155 is provided as extra argument.
7157 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * Added ~./silc directory handling. The directory includes the
7160 public and private keys for the client.
7162 Added silc_client_check_silc_dir, silc_client_create_identifier
7163 and silc_client_load_keys.
7165 * Implemented SILC protocol compliant public key. Added public
7166 and private key saving to and loading from files.
7168 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7169 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7170 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7171 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7172 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7174 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7175 silc_pkcs_load_[public/private]_key.
7177 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Added silc_server_get_route (route.[ch]) to get connection
7180 data for the fastest route for given ID.
7182 * Implemented INVITE command on client and server. The command
7183 were re-defined in the SILC Protocol Specification and the
7184 implementation now complies with the specification.
7186 * Implemented PING command on client and server.
7188 * Implemented NAMES command on client and server. The server side
7189 supports currently only normal server not router server yet.
7190 Some changes to NAMES definition in SILC protocol specification.
7192 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Implemented LEAVE command on client and server.
7196 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7197 again. This change was made to the protocol as well. Server
7198 should not violate the protocol specification anymore.
7200 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7203 was tested. SOCKS4 was not but should work anyway.
