43 make a section that accepts any incoming host, and have the
44 accepted public keys listed in the section.
46 Added functions silc_sever_[find/get]_public_key, added the
47 support for this actually to all connection sections but only
48 the Client section is currently allowed to specify multiple

199 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
201 * Added `user_count' to the SilcChannelEntry which now tells the
202 number of users on the channel. The user count is now saved
203 in normal server of global channels as well. Affected files
204 silcd/server.c, idlist.h, packet_receive.c and command.c.
206 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

218 Affected file lib/silcclient/client.c.
220 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
222 * ROBOdoc documented the lib/silcske/silcske.h, and improved
223 the SKE interface a bit.
225 * Fixed padding problem in PKCS#1. The padding was not actually
226 random since the random number generator was used incorrectly.
227 This security bug affects only when encrypting with PKCS#1, and
228 it is not currently used at all in SILC. SILC only use signing
229 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
231 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

297 * Added new configuration options and blocks:
298 keepalive_secs, reconnect_count, reconnect_interval,
299 reconnect_interval_max, reconnect_keep_trying and
300 require_reverser_lookup. Added ConnectionParam block, and
301 implemented the connection parameters when connecting as
302 initiator and when accepting connections as responder.

305 whether given configuration value has been given already.
307 Affected files silcd/serverconfig.[c], server.[c].
309 * Splitted the doc/example_silcd.conf.in. Separated the crypto
310 algorithm parts and created new file silcalgs.conf, that
311 is now included from the example_silcd.conf.in.
313 * Optimized the silc_server_connect_to_router_second to take
314 the connection configuration object from the SilcServerConnection
315 object instead of finding it during the connecting phase.
316 Added the configuration object to SilcServerConnection struct.
317 Affected files silcd/server_internal.h, server.c.
319 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

402 zero port also if the hostname is NULL because it could not
405 Call file transfer monitor callback now also if error occurs
406 during key agreement protocol.
408 Changed the silc_client_file_send interface to return the
409 SilcClientFileError instead of session id. The session ID
410 is returned into pointer provided as argument.

427 file lib/silcutil/silclog.c.
429 * Fixed the channel message payload decryption in the function
430 silc_channel_message_payload_decrypt to not modify the original
431 buffer before it is verified that the message decrypted
432 correctly. Otherwise, next time it is called with correct
433 channel key it won't encrypt since the payload is corrupted.
434 Affected file lib/silccore/silcchannel.c.
436 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

478 SilcClientEntry, and changed the SilcChannelEntry's
479 users list to SilcHashTable. The affected files are
480 lib/silcclient/idlist.[ch].
482 * Fixed a bug in hash table tarversing. While the hash table
483 is traversed with SilcHashTableList the table must not be
484 rehashed. It is now guaranteed that auto rehashable tables
485 are not rehashed while tarversing the list. Also defined that
486 silc_hash_table_rehash must not be called while tarversing
487 the table. Added function silc_hash_table_list_reset that must
488 be called after the tarversing is over. The affected files are
489 lib/silcutil/silchashtable.[ch].
491 * Changed all hash table traversing to call the new
492 silc_hash_table_list_reset in server and in client library.
494 * Added function silc_client_on_channel to return the
495 SilcChannelUser entry if the specified client entry is joined
496 on the specified channel. This is exported to application as
497 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

505 * Fixed the WHOWAS command's reply sending to support the
506 lists correctly. Affected file silcd/command.c.
508 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
510 * When sending JOIN command to router for processing the
511 sender's old command identifier was not saved back to the
512 sender's command context, fixed now. The affected file is
515 * Create the key in JOIN command of the router did not return
516 the channel key, added check for this. Affected file is
519 * Fixed a channel ID update bug in JOIN command reply. Do
520 not directly upgrade the ID but call the function
521 silc_idlist_replace_channel_id if the ID was changed.
522 Affected file silcd/command_reply.c.
524 * Fixed memory leaks from command calling if it would fail.
525 Affected file silcd/command.c.

541 in config file after new config file is done. Affected file
544 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
546 * Fixed a crash in server related to channel announcements.
547 Affected file silcd/server.c.
549 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Fixed memory leaks in silc_server_create_new_channel*
552 functions. Affected file silcd/server.c.
554 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
555 which ID was changed. This way the router will send the
556 user list for the channel again, and server won't be in
557 desync in some rare circumstances. Affected file is
558 silcd/packet_receive.c.
560 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
562 * Check for NULL socket pointer in the function
563 silc_server_packet_send_to_channel_real. Affected file
566 * Fixed the BAN notify handling to correctly remove ban
567 list. Affected file silcd/packet_receive.c.
569 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
571 * Fixed some header addition to Toolkit distribution in
572 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
574 * Added lib/silcclient/client_ops_example.h as an template
575 file for application programmers to quickly start using
576 the SilcClientOperation functions in their application.
577 Updated the lib/silcclient/README as well to tell about this
578 nice file made available.
580 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
582 * Call silc_server_remove_from_channels when removing client
583 entry when NO_SUCH_CLIENT_ID was received. Affected file
584 is silcd/command_reply.c.
586 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
588 * Added server & router operator statistics updating. Affected
589 file silcd/packet_receive.c and silcd/command.c.
591 * Fixed the SERVER_SIGNOFF notify handling on normal server
592 not to save the history information for clients. Same was
593 fixed earlier in remove_clients_by_server function, but not
594 here. Affected file silcd/packet_receive.c.
596 * Raised the default connection-retry count from 4 to 7 in
597 server. Affected file silcd/server.h.
599 * Cancel any possible reconnect timeouts when we start the
600 key exchange. Affected file silcd/server.c.
602 * Do not reconnect on connection failure when SCONNECT was
603 given. Affected files silcd/server.[ch].
605 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
607 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
609 * Fixed the NICK command to always give the unformatted
610 nickname to the one giving the NICK command. If unformatted
611 nickname is cached already it will be formatted and the
612 local entry will always get the unformatted nickname.
613 Affected file lib/silcclient/idlist.c.
615 * Fixed some double frees from client library commands.
616 Affected file is lib/silcclient/command.c.
618 * Fixed CUMODE command in server to assure that no one can
619 change founder's mode than the founder itself, there was a
620 little bug. Affected file silcd/command.c.
622 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
624 * Removed the SilcClientCommandDestructor from the client
625 libary, it is not needed anymore. Affected files are
626 lib/silcclient/silcapi.h, command[_reply].[ch],
627 client_notify, idlist.c.
629 * Fixed GETKEY command to first resolve client, and then
630 resolve the server only if the client was not found, instead
631 of resolving both at the same time. Affected file is
632 lib/silcclient/command.c.
634 * Added silc_client_start_key_exchange_cb and lookup the
635 remote hostname and IP address before starting the key
636 exchange with server. The affected file is
637 lib/silcclient/client.c.
639 * The server's public key is now saved using the IP address
640 of the server and not the servername for the filename.
641 The hostname public key filename is checked as an fall back
642 method if the IP address based filename is not found.
644 Fixed the GETKEY command to save the fetched server key
647 Print the remote server's hostname now when new key is
648 received during connection process. Affected file is
649 irssi/src/silc/core/client_ops.c.
651 * Return always our own public key to the client if it asks
652 for it with GETKEY command. Affected file silcd/command.c.
654 * Removed the use_auto_addr variable from default config
655 file since it was in wrong section. Affected file is
658 * Fixed TOPIC_CHANGE notification to not route it when it
659 was sent using silc_server_send_notify_to_channel function.
660 Affected file silcd/command.c.
662 * Fixed silc_server_send_notify_kicked to send the kicker's
663 Client ID also, it was missing. Affected files are
664 silcd/command.c, silcd/packet_send.[ch].
666 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
668 * Do not save client history information in SERVER_SIGNOFF.
669 Fixes the bug in normal server that it does not detect
670 the client becoming valid after the server becomes back
671 online. Affected file silcd/server_util.c.
673 * Added `sock_error' field into the SilcSocketConnection
674 context. When error occurs during socket operation (read
675 or write) the error is saved. Added also new function
676 silc_socket_get_error to return human readable socket error
677 message. Affected files are lib/silcutil/silcsockconn.[ch],
678 lib/silcutil/unix/silcunixsockconn.c, and
679 lib/silcutil/win32/silcwin32sockconn.c.
681 * The server now prints the socket error message in the
682 signoff for client. Affected file silcd/server.c.
684 * Fixed the `created' channel information sending from router
685 to server in JOIN command. Checks now whether the channel
686 really was created or not and set it according that.
688 Fixed the JOIN command to use the client entry's current
689 ID during the joining procedure instead of the one it sent
690 in the command (it is checked though), since it can change
691 between the packet processing and command processing, and
692 would just case unnecessary pain in the client end. Affected
693 file silcd/command.c.
695 * Fixed a channel key payload sending to use correct channel
696 ID when the server was forced to change the channel's ID by
697 router. Router sent the key payload with the old Channel ID.
698 Affected file silcd/packet_receive.c.
700 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
702 * Call silc_server_save_channel_key only if the key payload
703 was provided in the JOIN command's command reply. Affected
704 file silcd/command_reply.c.
706 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Fixed silc_mp_sizeinbase to return the value correctly with
709 MPI. Affected file lib/silcmath/mp_mpi.c.
711 * Fixed the stop_server signal to correctly stop the scheduler
712 and gracefully stop the server when SIGTERM or SIGINT signals
713 are received. Affected file silcd/silcd.c.
715 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
717 * Simple handling of TERM and HUP signals. Also added some log
718 flushing call around. Affected file is
721 * Fixed small bugs in silclog.c. Now buffering output will take
722 effect after 10 seconds since startup: This will ensure that
723 no important startup messages are lost. Also output redirection
724 will preserve original format ([Date] [Type] message).
725 Affected file is lib/silcutil/silclog.c.
727 * Added two options to the config file, in the logging section:
728 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
729 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
731 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
733 * Do not print the warning about log files not being initialized
734 more than once to avoid excess logging. Affected file is
735 lib/silcutil/silclog.c.
737 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
738 the SIM copying in make install in Makefile.am.pre.
740 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
742 * Rewritten silclog APIs. Globally interesting changes follows:
743 silc_log_set_files() changed to silc_log_set_file().
744 silc_log_set_callbacks() changed to silc_log_set_callback().
745 ROBOdoc documented silclog header file.
746 SilcLogCb now returns bool to wether inihibit the default
747 handler or not (to keep the old behaviour return always TRUE).
748 The new APIs should also fix the problem of the
749 silcd_error.log file that was written in the current directory.
752 Log files streams will remain opened after silc_log_set_file()
753 call, means less CPU usage notably on high traffic servers.
754 File streams are now full buffered, and flushed to the disk
755 every 5 minutes, lesses HD activity and CPU usage.
756 Messages can be redirected, allowing admins to configure
757 one single logfile for all server messages.
758 the silc_log_quick global variable to activate fast-logging.
759 Affected files lib/silcutil/silclog.[ch]
761 * Changed some code to conform new silclog APIs. Affected
762 files are doc/example_silcd.conf.in, silcd/server.c
763 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
766 * Fixed a memory leak that could occur in some situations.
767 Affected file silcd/serverconfig.c.
769 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
771 * Added the silc_client_del_client to remove the client from
772 all channels as well. Affected file lib/silcclient/idlist.c.
774 * Fixed the client library to correctly remove the client
775 from all channels when the client entry is being destroyed.
776 Affected file lib/silcclient/client_notify.c, command.c.
778 * Added auto-nicking support to the client library. If the
779 applicatio now sets client->nickname it will be sent to the
780 server after connecting by the library. This way for example
781 SILCNICK (or IRCNICK) environment variables will have effect
782 and always change the nickname automatically to whatever
783 it is wanted. Affected file lib/silcclient/client.[ch].
785 * Renamed silc_server_command_bad_chars to the
786 silc_server_name_bad_chars and moved it to the
787 silcd/server_util.[ch]. Added also new function
788 silc_server_name_modify_bad to return nickname that
789 includes bad characters as new nickname without those
790 bad characters. This check and modify is now used in
791 silc_server_new_client when the username is initially set
792 as nickname, so it must be checked to be valid nickname.
793 Affected file silcd/packet_receive.c.
795 * The nickname length is now taken from the packet for real
796 and not trusted to strlen() since it clearly can return
797 wrong length for nickname including bad characters. This
798 also applies to channel names. Affected file silcd/command.c.
800 * Removed the lib/silcsilm/modules directory. Modules are now
801 compiled into the lib/silcsim. Fixed the copying of the
802 modules to follow symbolic links in Makefile.am.pre.
804 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
806 * Fixed silc_string_regexify list creation. Fixes bugs with
807 BAN and INVITE commands in server. The affected file is
808 lib/silcutil/unix/silcunixutil.c.
810 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
812 * Removed the command destructor entirely from the server's
813 command and command reply routines. It is not needed, and
814 its usage was buggy and caused crashes. Affected files are
815 silcd/command[_reply].[ch].
817 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Cancel protocol and NULL sock->protocol if timeout
820 occurred during protocol. Affected file silcd/server.c.
822 * Cancel protocol timeouts always before calling the final
823 callback, to assure that after final callback is called
824 no other state will be called for the protocol anymore.
825 Affected file silcd/protocol.c.
827 * Print error log if incoming connection configuration could
828 not be found. Affected file silcd/server.c.
830 * Fixed JOIN command to correctly save the founder mode
831 to the client on normal SILC server, when the channel
832 was created by the router. Affected file silcd/command.c.
834 * Fixed LIST command (hopefully) to send correct reply
835 packets. Affected file silcd/command.c.
837 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
839 * The silc_packet_receive_process now returns FALSE if the
840 read data was invalid packet, and TRUE if it was ok.
842 The server now checks that if unauthenticated connection
843 sends data and its processing fails the server will close
844 the connection since it could be a malicious flooder.
846 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
848 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Make sure the warning about error opening a log file is
851 printed only once and not everytime it fails (produces
852 too much useless log). Affected file lib/silcutil/silclog.c.
854 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
856 * Made the silc_server_daemonise() function more readable.
857 Affected file silcd/server.c.
859 * Pid file is now optional, the user may comment it out from
860 the config file. Removed define SILC_SERVER_PID_FILE, we
861 don't need a default any longer. Affected file
862 configure.in.pre, lib/Makefile.am.pre.
864 * Make some use of the pid file. The server now dies at startup
865 if it detects a valid pid file on his path. The server would
866 die anyway in this circumstance, because of the bind() failure.
867 Affected file silcd/silcd.c.
869 * No longer compiling lib/dotconf.
871 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
873 * Fixed JOIN command parsing not to crash. Affected file
874 lib/silcclient/command.c.
876 * Fied the NICK_CHANGE notify to add the new client entry
877 even it is resolved. This removes an <[unknown]> nick
878 thingy bug in the client. Affected file is
879 lib/silcclient/client_notify.c.
881 * Do not try to allocate 0 bytes (efence does not like it)
882 in lib/silccore/silccomand.c when encoding payload.
884 * Do not take IRCNICK as nickname in Irssi SILC client since
885 it is not possible to set nickname before hand connecting
886 the server (TODO has an entry about adding auto-nicking
889 * Changed the silc_server_command_pending to check whether
890 there already exists an pending entry with the specified
891 command, command identifier and pending callback. This is
892 to fix IDENTIFY and WHOIS related crashes that may register
893 multiple pending commands with same identifier. Affected
894 file silcd/command.c.
896 * Fixed the server to reconnect to the router even if it
897 was already reconnecting and EOF was received. This to
898 fix a possibility that the server wouldn't ever try to
899 auto-reconnect to the router. Affected file silcd/server.c.
901 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
903 * Fixed the server's password authentication to use the
904 length of the locally saved password, and not the one
905 sent in the packet. Affected file silcd/protocol.c.
907 * Fixed same password authentication problem in the
908 Authentication Payload handling routines in
909 lib/silccore/silcauth.c.
911 * Yet another password authentication problem fixed with
912 channel password handling in silcd/command.c.
914 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
916 * If first character of string in silc_parse_userfqdn is '@'
917 then do not parse it. Affected file is
918 lib/silcutil/silcutil.c.
920 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
922 * Fixed minor bug in IDENTIFY command reply sending, which
923 caused various weird problems during JOIN when it was
924 resolving names for users. Affected file silcd/command.c.
926 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Fixed the IDENTIFY command reply sending to chech better valid
929 clients. It was possible to send incomplete list of replies.
930 Affected file silcd/command.c.
932 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
934 * Added silc_client_command[s]_[un]register functions now to
935 dynamically register the commands in client library. Removed
936 the static table of commands. This allows the client library
937 to call commands without causing the application to know about
938 what commands library has called.
940 Removed the INFO command reply kludge to detect when the command
941 was called by library. Now library use its own command reply
942 function for INFO command.
944 Added function silc_client_command_call to call a command.
945 Application can use it to call command, not access the structure
948 Now all commands that are sent by the client library (not
949 explicitly sent by application) use own command reply functions.
951 Affected files around lib/silcclient/ and in
952 irssi/src/silc/core/.
954 * Fixed the WHOIS command reply sending to chech better valid
955 clients. It was possible to send incomplete list of replies.
957 Fixed the WHOIS and IDENTIFY to send the request to router
958 if normal server did not do it and did not find any results.
960 Affected file silcd/command.c.
962 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Moved the internal data from SilcClient context into its
965 own file, not accesible to application. Affected files
966 lib/silcclient/client.h and lib/silcclient/client_internal.h,
967 and other files in client library.
969 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Added doc/examples installation target in Makefile.am.pre.
974 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
976 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
977 commands the found client entry will be removed from the
978 cache, after notifying application about the error. Affected
979 file lib/silcclient/command_reply.c.
981 * Changed the /MSG to check for exact nickname user gave, and
982 not let `nick' match `nick@host' if it is only one found. Now,
983 user must type the exact nickname (like nick@host2) even if
984 there are no more than one same nicks found. This is to avoid
985 a possibility of sending nickname to wrong nickname since
986 `nick' could match `nick@host'. Affected file is
987 irssi/src/core/silc-servers.c.
989 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Do not print "you are now server operator" or similar when
992 giving /away command. Affected files are
993 irssi/src/silc/core/client_ops.c, silc-servers.h.
995 * Made the silc_server_command_pending_error_check to send
996 the same command reply payload it received back to the
997 original sender of the command. This way all arguments
998 that was received by the server will be received by the
999 client too. Affected file silcd/command.c.
1001 * Added the silc_idcache_add to return the created cache entry
1002 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1004 * Add global clients to expire if they are not on any channel.
1005 This is because normal server will never know if they signoff
1006 if they are not on any channel. The cache expiry will take
1007 case of these entries. This is done by normal servers only.
1008 The affected files are silcd/command_reply.c,
1009 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1011 * If server receives invalid ID notification for WHOIS or
1012 IDENTIFY and the ID exists in the lists, it is removed.
1013 Affected file silcd/command_reply.c.
1015 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1016 in client then client entry that it matches is searched and
1017 the nickname is printed on the screen for user. Affected
1018 file irssi/src/silc/core/client_ops.c.
1020 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Use cache entry expire time in the LIST command reply to
1023 purge old entries from the cache after the LIST command
1024 reply has been received. This way we don't have non-existent
1025 entries in the cache for too long. Affected file is
1026 silcd/command_reply.c.
1028 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * If we are normal server, and we've not resolved client info
1031 in WHOIS or IDENTIFY from router, and it is global client,
1032 we'll check whether it is on some channel. If it is not
1033 then we cannot be sure about its validity and will resolve it
1034 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1035 file silcd/command.c.
1037 * Search channel by name (if possible) rather than by ID
1038 in IDENTIFY command's command reply. Affected file is
1039 silcd/command_reply.c.
1041 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1044 Updated specs and implemented it. Affected file silcd/command.c,
1045 silcd/packet_send.c and silcd/packet_receive.c.
1047 * Implemented the <founder auth> payload handling in the JOIN
1048 command. If provided all conditions for channel joining
1049 except requirement to provide correct passphrase can be
1050 overrided by the channel founder. Updated the protocol specs.
1051 Affected file silcd/command.c.
1053 Added support for founder auth in JOIN command in client
1054 library. Fixed the parsing of the JOIN command now to support
1055 all options as they should be. The affected file is
1056 lib/silcclient/command.c.
1058 * Optimized the WHOIS and IDENTIFY commands to send the request
1059 to router only if it includes nicknames or other names. If
1060 they include only IDs then check the local cache first before
1061 routing. Affected file is silcd/command.c.
1063 * Added channels topic announcements. Affected file is
1064 silcd/packet_receive.c and silcd/server.c.
1066 * Fixed the silc_server_send_notify_topic_set to really destine
1067 the packet to channel. Affected file silcd/packet_send.c.
1069 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1070 library. Affected file lib/silcclient/client_notify.c.
1072 * Added UMODE announcements. Affected file silcd/server.c.
1074 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1076 * Memory leak fixes in:
1078 lib/silcutil/silcsockconn.c
1079 lib/silcske/silcske.c
1080 lib/silcske/groups.c
1082 lib/silccrypt/silcpkcs.c
1083 lib/silccore/silccommand.c
1084 lib/silccore/silcidcache.c
1089 * ROBOdoc documented the lib/silcske/groups.h file and a
1090 bit changed the interface for better.
1092 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1094 * Update the client entry context in the ID cache after
1095 nick change. Affected file lib/silcclient/command.c.
1096 Fixes the CUMODE command when regaining founder privileges,
1097 and a little WHOIS problem.
1099 * Fixed silc_net_gethostbyname to correctly call the
1100 inet_ntop. Affected file lib/silcutil/silcnet.c.
1102 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1104 * Added IPv6 support checking to the configure.in.pre, added
1105 also --enable-ipv6 option to override the check. Affected
1106 file configure.in.pre.
1108 * The silc_thread_create now calls the start function
1109 directly if threads support is not compiled in. Removes
1110 ugly #ifdef's from generic code. Affected files are
1111 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1113 * Added silc_net_gethostby[name/addr]_async to asynchronously
1114 resolve. Affected files are lib/silcutil/silcnet.[ch].

1120 file is silcd/serverid.c.
1122 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1124 * Added silc_net_gethostby[addr/name] into the
1125 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1126 routines. Added silc_net_is_ip[4/6]. Affected file is
1127 lib/silcutil/unix/silcunixnet.c. All routines that take
1128 address as argument now supports both IPv4 and IPv6 addresses.
1130 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1132 * Fixed LIST command reply sending in server. Affected file
1135 * Server now sends the kicker's client ID in the KICK notify
1136 to the kicked client. Affected file silcd/command.c.
1138 * The client library now parses the kickers client ID and
1139 UI displays it. Affected files lib/silcclient/client_notify.c
1140 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1142 * Made all payload parsing function prototypes consistent.
1143 They all take now const unsigned char * and uint32 pair as
1144 the payload data instead of SilcBuffer. Changes all around
1145 the source tree. Other unsigned char* -> const unsigned char*
1146 changes around the tree as well.
1148 * Optimized SFTP client and server packet sending not to
1149 allocate new buffer for each packet but to recycle the
1150 first allocated buffer. Affected files are
1151 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1153 * Optimized the SFTP client to use SilcList instead of
1154 SilcDList for requests, because it is faster. Affected file
1155 is lib/silcsftp/sftp_client.c.
1157 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1158 into lib/silccore/silcid.[ch].
1160 Renamed silcpayload.[ch] into silcargument.[ch].
1162 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1164 * If client entry is deleted with active key agreement
1165 session, abort the session.
1167 The silc_client_abort_key_agreement now calls the completion
1168 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1170 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1173 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Don't use __restrict in older GCC's. Affected file is
1176 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1178 * silc_net_localhost now attempts to reverse lookup the
1179 IP/hostname. Affected file lib/silcutil/silcnet.c.
1181 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1182 command. It can be used to gain founder privileges at
1183 the same time when joining the channel.
1185 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1186 kicker's client ID as well. Updated protocol specs.
1188 Defined that the server must send SILC_COMMAND_IDENTIFY
1189 command reply with error status to client who sent
1190 private message with invalid client ID.
1192 Updated the protocol specification.
1194 * Added silc_server_send_command_reply to send any
1195 command reply. Affected file silcd/packet_send.[ch].
1197 * Added silc_id_payload_encode_data to encode ID payload
1198 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1200 * The server now send IDENTIFY command reply with error
1201 status if client ID in private message is invalid. Affected
1202 file silcd/packet_receive.c.
1204 * Save the server key file with server's IP address in
1205 the filename instead of hostname. The affected file is
1206 irssi/src/silc/core/client_ops.c.
1208 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1213 * Added libtool support for compiling shared objects in
1214 lib/silcsim. Affected file configure.in.pre and
1215 lib/silcsim/Makefile.am. Original patch by cras.
1217 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Pid file configuration, and server's config file fixes
1220 patch by toma. Updated CREDITS file.
1222 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Fixed silc_client_channel_message to not try to decrypt
1225 the message twice if it resolved the destination client
1226 information. This could cause of dropping one channel
1227 message. Affected file lib/silcclient/client_channel.c.
1229 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1231 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1232 lib/silcclient/client.c. This function is used when the SILC
1233 Client is run under some other scheduler, or event loop or
1234 main loop. On GUI applications, for example this may be
1235 desired to used to run the client under the GUI application's
1236 main loop. Typically the GUI application would register an
1237 idle task that calls this function multiple times in a second
1238 to quickly process the SILC specific data.
1240 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1242 * Fixed silc_server_drop() for dropping the supplementary
1243 groups as well, this could cause a security hole on some
1246 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1248 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1251 * Write PID file after dropping privileges. Added -F option
1252 to run server on foreground. A patch by debolaz.
1253 Affected files silcd/server.c, silcd/silcd.c.
1255 * Fixed MOTD to return the MOTD file server name. Affected
1256 file silcd/command.c.
1258 * Added INFO command reply handling to the Irssi SILC Client.
1259 Affected file irssi/src/silc/core/client_ops.c.
1261 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Fixed the silc_idcache_list_* routines to really support
1264 the dynamic list. Fixes a crash. Affected file is
1265 lib/silccore/silcidcache.c.
1267 * Fixed the LIST command reply to really call LIST command's
1268 pending callbacks. Affected file silcd/command_reply.c.
1270 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Update conn->local_entry->nickname after giving NICK
1273 command. Affected file lib/silcclient/command.c.
1275 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1277 * Added the [pid] option to the silcd configuration file
1279 Affected files: serverconfig.[ch] and silcd.c
1281 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Save fingerprint in WHOIS command reply in server.
1284 Affected file silcd/command_reply.c.
1286 * Fixed NICK commands pending callback registration.
1287 Affected file lib/silcclient/command.c.
1289 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * Use ++server->cmd_ident when sending commands in server,
1292 instead of random number. Affected file silcd/command.c.
1294 * Fixed GETKEY command reply to call actually GETKEY pending
1295 command callbacks. Affected file silcd/command_reply.c.
1297 * A bit stricter check for nicknames. Check for same nickname
1298 in NICK command also. Affected file silcd/command.c.
1300 * Do not call INFO command everytime client ID changes, only
1301 during first connecting. Affected file lib/silcclient/client.c.
1303 * Set the new nickname only after successful command reply for
1304 NICK command is returned by server. Affected file
1305 lib/silcclient/command.c.
1307 * Remove nicknames from nicklist during server_signoff notify.
1308 Should fix /NAMES bit more. The affected file is
1309 irssi/src/silc/core/silc-channels.c.
1311 * Added `fingerprint' field to the SilcIDListData in the
1312 silcd/idlist.h to hold the fingerprint of the client's
1315 Send the fingerprint of the client's public key in WHOIS
1318 Affected files silcd/command.c, and silcd/idlist.[ch].
1320 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1321 create fingerprint from given data.
1323 * Show the fingerprint of the client's public key in WHOIS.
1324 Affected files irssi/src/module-formats.[ch] and
1325 irssi/src/silc/core/client_ops.c.
1327 * Format the multiple same nicknames also during JOIN and
1328 NICK_CHANGE notifys. Affected file is
1329 lib/silcclient/client_notify.c.
1331 * Do not print error on screen for invalid private message
1332 payload since it can come if someone is sending private
1333 messages with wrong key. Affected file
1334 lib/silccore/silcprivate.c.
1336 * Fixed multiple concurrent /PING crash. Affected file
1337 lib/silcclient/command.c.
1339 * Changed the wrong ID encoding. All IP addresses must be
1340 in MSB first order in encoded format. They were encoded
1341 wrong and was in LSB format. Affected files are
1342 silcd/serverid.c, lib/silcutil/silcutil.c.
1344 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1346 * Call the `connect' client operation through the scheduler
1347 in case of error. Affected file lib/silcclient/client.c.
1349 * Call the `failure' client operation even if the error
1350 occurred locally during a protocol. Affected file is
1351 lib/silcclient/protocol.c.
1353 * Added support of sending LIST command to router from normal
1354 server. This way normal server can get list of all channels
1355 in the network too. Fixed the channel list sending in the
1356 server too. Affected files are silcd/command.c, and
1357 silcd/command_reply.[ch].
1359 * Added silc_server_update_channels_by_server and
1360 silc_server_remove_channels_by_server. They are used during
1361 disconnection of primary router and in backup router protocol.
1362 Affected file silcd/server_util.[ch], silcd/server.c and
1363 silcd/server_backup.c.
1365 * Fixed channel adding to global list in IDENTIFY command
1366 reply in server. Affected file silcd/command_reply.c.
1368 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * If the incoming packet type is REKEY or REKEY_DONE process
1371 that packet always synchronously. Fixes yet another MAC
1372 failed error on slow (dialup) connections. Affected file
1373 lib/silcclient/client.c and silcd/server.c.
1375 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Call check_version SKE callback for initiator too. Affected
1378 file lib/silcske/silcske.c.
1380 * Implemented fix for security hole found in the SKE that was
1381 fixed in the specification few days back; the initiator's
1382 public key is now added to the HASH value computation.
1383 Added backwards support for the old way of doing it too, for
1384 old clients and old servers. Affected file is
1385 lib/silcske/silcske.c.
1387 * Enabled mutual authentication by default in SKE. If initiator
1388 is not providing mutual authentication the responder will
1389 force it. This will provide the proof of posession of the
1390 private key for responder. The affected files are
1391 lib/silcclient/protocol.c and silcd/protocol.c.
1393 * Do not cache anymore the server's public key during SKE.
1394 We do mutual authentication so the proof of posession of
1395 private key is done, and if the server is authenticated in
1396 conn auth protocol with public key we must have the public
1397 key already. Affected file silcd/protocol.c.
1399 * Added new global debug variable: silc_debug_hexdump. If
1400 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1401 file lib/silcutil/silclog.[ch].
1403 * Fixed compilation warning due to char * -> const char *.
1404 Affected files lib/silcutil/silcnet.h, and
1405 lib/silccore/silcauth.[ch].
1407 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Fixed CMODE command when new channel key was created. If
1410 the creation failed the old key was removed. Next time giving
1411 same command would crash the server since the old key was
1412 freed already. Affected file silcd/command.c.
1414 * Fixed the silc_server_announce_get_channels to not crash
1415 on reconnect. Affected file silcd/server.c.
1417 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Added silc_log_set_debug_string function to set a regex
1420 string to match for debug output. Only the function names,
1421 or filenames matching the given debug string is actually
1422 printed. This way it is possible to filter out those debug
1423 strings that user is not interested in.
1425 Fixed a bug in silc_string_regexify.
1427 Affected files lib/silcutil/silclog.[ch], and
1428 lib/silcutil/unix/silcunixutil.c.
1430 * Changed the -d options in both server and Irssi SILC client
1431 to take the debug string as argument. Affected files
1432 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1434 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Added silc_hash_babbleprint to create a Bubble Babble
1437 Encoded fingerprint. The encoding is developed by Antti
1438 Huima (draft-huima-babble-01.txt), and it creates human
1439 readable strings out of binary data. Affected file
1440 lib/silccrypt/silchash.[ch].
1442 * Print the babble print now in addition of fingerprint as well
1443 in Irssi SILC client. Affected files are
1444 irssi/src/fe-common/silc/module-formats.[ch],
1445 irssi/src/fe-common/silc/core/client_ops.c.
1447 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Fixed a security problem found in SKE. The initiator's
1450 public key too is now added to the HASH hash value creation
1451 which is signed by the responder to create the SIGN value.
1452 This will prevent anyone in the middle to lie to the responder
1453 about the initiator's public key. If this is done now, the
1454 man in the middle will get caught. Updated the protocol
1457 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Better installation directory handling. Configure module
1460 paths and other paths automatically to example_silc* files
1461 in doc/. A patch by toma.
1463 * Fixed compiler warning from MPI library, and from SILC RNG.
1466 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1467 It can be configured with ./configure. A patch by toma.
1469 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1471 * Find correct make to use in prepare-clean. A patch by
1472 toma. Affected file prepare-clean.
1474 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1476 * Added irssi variables use_auto_addr, auto_bind_ip,
1477 auto_bind_port and auto_public_ip.
1479 * Changed the interface for silc_client_send_key_agreement
1480 in lib/silcclient/silcapi.h
1484 irssi/src/silc/core/silc-core.c
1486 lib/silcclient/silcapi.h
1487 irssi/src/silc/core/silc-channels.c
1488 lib/silcclient/client_keyagr.c
1491 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Added silc_pkcs_public_key_compare to compare two
1494 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1496 * Check that the client who set the founder mode on the
1497 channel is the same client that is giving the founder
1498 mode to itself. It is done by comparing the saved public
1499 key (it is saved even in the authentication is passphrase).
1500 Affected file silcd/command.c.
1502 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Do not process packet for disconnected socket connection.
1505 Affected file lib/silccore/silcpacket.c.
1507 * Process the DISCONNECT packet through scheduler in the
1508 client library. Affected file lib/silcclient/client.c.
1510 * Fixed the silc_client_packet_parse to not to increase
1511 the packet sequence number if the conn->sock and the
1512 current socket connection is not same. This can happen
1513 for example during key agreement when the conn includes
1514 multiple socket connections (listeners). Affected file
1515 lib/silcclient/client.c.
1517 * The sender of the file transfer request now provides also
1518 the pointer (listener) for the key exchange protocol. If
1519 the listener cannot be created then it sends empty key
1520 agreement and lets the receiver provide the listener.
1522 Added `local_ip' and `local_port' arguments to the
1523 silc_client_file_send. If they are provided they are used,
1524 if not then it will attempt to find local IP address, if
1525 not found or bind fails then the remote client will provide
1528 Affected files are lib/silcclient/client_ftp.c and
1529 lib/silcclient/silcapi.h.
1531 * Extended the FILE SEND command to support defining the
1532 local IP and port for key exchange listener. They are
1533 optional. Affected file irssi/src/silc/core/silc-servers.c.
1535 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Defined to WHOIS command reply the sending of fingerprint
1538 of the client's public key (if the proof of posession of the
1539 corresponding private key is verified by the server).
1540 Updated to the protocol specification.
1542 * Added support of receiving the client's public key's
1543 fingerprint in command reply in client library. Affected
1544 file is lib/silcclient/command_reply.c, and
1545 lib/silcclient/idlist.[ch].
1547 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1549 * Do not send over 128 chars long nickname to the server
1550 in NICK command. Affected file lib/silcclient/command.c.
1552 * Do not send over 256 chars long channel names to the server
1553 in JOIN command. Affected file lib/silcclient/command.c.
1555 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Assure that silc_server_close_connection cannot be called
1558 twice for same socket context. Affected file is
1561 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Send error message to application if opening file for
1564 writing during file transfer fails. Affected file is
1565 lib/silcclient/client_ftp.c.
1567 Remove all file transfer sessions for a client that we're
1568 removing from ID cache.
1570 Affected file is lib/silcclient/client_ftp.c.
1572 * Fixed silc_net_addr2bin to return correct address. Affected
1573 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1575 * Fixed file transfer session removing on signoff notify.
1576 Affected file irssi/src/silc/core/silc-servers.c.
1578 * Added the SilcClientFileError to be returned in the monitor
1579 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1580 Affected file lib/silcclient/silcapi.h.
1582 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Fixed a crash in silc_client_ftp_free_sessions and
1585 silc_client_ftp_session_free_client. Affected file
1586 lib/silcclient/client_ftp.c.
1588 * Added `disabled' field in the SilcChannelEntry in the server
1589 to indicate if the server entry is disabled. Affected file
1590 silcd/idlist.h, silcd/command[_reply].c.
1592 * SILC server adds now /var/run/silcd.pid everytime it is
1593 started. Affected file silcd/silcd.c.
1595 * Added silc_server_packet_send_clients to send a packet to
1596 the provided table of client entries. Affected file
1597 silcd/packet_send.[ch].
1599 * Fixed a crash in client resolving in client_prvmsg.c in
1600 client library. Affected file lib/silcclient/client_prvmsg.c.
1602 * Do not actually remove the client directly from ID cache
1603 during SERVER_SIGNOFF, but invalidate it. This way we
1604 preserve the WHOWAS info for the client. Affected file
1605 silcd/server_util.c.
1607 * Fixed SERVER_SIGNOFF notify handling in the server. The
1608 server is now able to process incoming SERVER_SIGNOFF notify
1609 for a server that it doesn't even know about. It will remove
1610 the clients provided in the notify. Affected file
1611 silcd/packet_receive.c.
1613 * Check for partial packet in data queue after every packet that
1614 was found from the queue. Return and wait for more data if
1615 there is partial data in queue. Affected file is
1616 lib/silccore/silcpacket.c.
1618 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Added SilcClietFileError enum to indicate error in
1621 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1622 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1623 Affected files lib/silcclient/silcapi.h and
1624 lib/silcclient/client_ftp.c.
1626 * Check that newsize in silc_buffer_realloc is larger than
1627 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1629 * Added better monitor of file transfers. It now monitors
1630 key agreement protocol during the file transfer too. Added
1631 error reporting too. Affected files
1632 irssi/src/silc/core/silc-servers.c,
1633 irssi/src/fe-common/silc/module-formats.[ch].
1635 * Wrote a help file for FILE command.
1637 * Added silc_rng_global_get_byte_fast to get not-so-secure
1638 random data as fast as possible. Random data is read from
1639 /dev/urandom if available and from the SILC RNG if not
1640 available. It is used in padding generation. Affected file
1641 lib/silccrypt/silcrng.[ch].
1643 * All packets in client library are now processed synchronously.
1644 Optimized packet processing a lot. Affected file
1645 lib/silcclient/client.c.
1647 * All server connection packets are processing synchronously
1648 now in server, to optimize packet processing. Affected file
1651 * Include files are installed now only in Toolkit distribution
1652 if make install is given. Affected files: all Makefile.am's.
1654 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * Assure that silc_client_notify_by_server_resolve does not
1657 resolve the client information multiple times. If it cannot
1658 be found by the first it cannot be found at all. Affected
1659 file lib/silcclient/client_notify.c.
1661 * Fixed WHOWAS command reply calling. Affected file
1662 lib/silcclient/command_reply.c.
1664 * Removed all references to silc_idlist_get_client from the
1665 Irssi SILC client since that call is internal call used by
1666 the library. The Irssi SILC client will use now client
1667 retrieval functions found in silcapi.h.
1669 * Fixed a bug in resolving nickname info before sending
1670 private message. It used freed memory. Affected file
1671 irssi/src/silc/core/silc-servers.c.
1673 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Assure my_channels statistics cannot go negative in server.
1676 Affected files silcd/server.c, silcd/server_util.c.
1678 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1692 * Added silc_net_localip to return local host's IP address.
1693 Affected file lib/silcutil/silcnet.[ch].
1695 * If key exchange or rekey protocol is active for a connection
1696 parse all packets syncronously since there might be packets
1697 in packet queue that we are not able to process without first
1698 processing packets before them. Affected file silcd/server,
1699 lib/silcclient/client.c.
1701 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1702 whether library should continue processing the packet.
1703 Affected file lib/silccore/silcpacket.h.
1705 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1734 lib/silcutil/silcutil.[ch].
1736 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Resolve the client info when received private message or
1739 channel message for a client which nickname we don't know.
1740 Affected files lib/silcclient/client_prvmsg.c and
1741 lib/silcclient/client_channel.c.
1743 * Do not crash in /KEY if client is not connected. Affected
1744 file irssi/src/silc/core/silc-channels.c.
1746 * Added SilcClientStatus field to the SilcClientEntry in the
1747 lib/silcclient/idlist.h.
1749 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1750 is incomplete and is being resolved, it won't be resolved
1753 Make sure also that USERS command reply does not resolve
1754 twice information. Affected file is
1755 lib/silcclient/command_reply.c.
1757 Make sure that silc_client_get_clients_by_list does not
1758 resolve twice same information.
1760 * Check for valid client->id in the silc_server_free_client_data.
1761 Affected file silcd/server.c.
1763 * Fixed /GETKEY nick@server not to crash if the server entry
1764 is not found. Affected file lib/silcclient/command.c.
1766 * Fixed the silc_server_check_cmode_rights to check the
1767 requested modes correctly. Affected file silcd/command.c.

1771 * Better checks for non-printable chars in nick added.
1772 Affected file silcd/command.c.
1774 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Call the silc_server_udpate_servers_by_server in the
1777 primary router that comes back online in the backup resuming
1778 protocol. Otherwise it routes packets wrong. Affected file
1779 silcd/server_util.[ch], silcd/server_backup.c.
1781 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1784 lib/silcutil/silcbuffmt.[ch].
1786 * Redefined the SILC packet header to include the padding
1787 length. Affected file lib/silccore/silcpacket.[ch].
1789 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1790 length for maximum padding up to 128 bytes). Affected
1791 file lib/silccore/silcpacket.h.
1793 * Removed all backwards support for old 0.5.x MAC thingies.
1794 The SILC packet header change makes it impossible to be
1795 backwards compatible.
1797 * Send the ENDING packet with timeout in the backup resuming
1798 protocol. This is to assure that all routers has connected
1799 to the primary router. Affected file silcd/server_backup.c.
1801 * Changed the RNG to take the first IV from random data. It
1802 used to take it from zero actually. Changed the RNG also
1803 to use /dev/urandom during session. /dev/random is used
1804 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1806 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Changed the SILC packet header to have the first two bytes
1809 (the packet length) encrypted. Affected files aroung the
1810 code tree, lib/silccore/silcpacket.[ch]. Removed the
1811 SilcPacketCheckDecrypt callback. It is not needed anymore
1812 since the silc_packet_receive_process will determine now
1813 whether the packet is normal or special.
1815 * Implemented the unidirectional MAC keys. Affected files
1816 lib/silcske/silcske.c, silcd/protocol.c and
1817 lib/silcclient/protocol.c.
1819 * Implemented the packet sequence number to the MAC computation.
1820 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1821 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1822 lib/silcclient/protocol.c.
1824 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Allow backup router to announce servers. All servers
1827 announced by backup router are added to the global list
1828 automatically. Update hte server's socket to our primary
1829 router also when backup router announces a server.
1830 Affected file silcd/packet_receive.c.
1832 * Do not update the client->router in the function
1833 silc_server_udpate_clients_by_server if the client is on
1834 global list. We might fail to find any specific server
1835 for locally connected clients and local cell clients. They
1836 should still use the `from' and not `to' as client->router.
1837 This fixes backup router resuming protocol. Affected file
1838 silcd/server_util.c.
1840 * Decrease channel statistics count only if the channel
1841 deletion worked. Affected files are silcd/server.c and
1842 silcd/server_util.c.
1844 * Added silc_server_update_servers_by_server to update origin
1845 of all server entries. Used during backup router protocol.
1846 Affected files silcd/server_util.[ch], silcd/server.c. and
1847 silcd/backup_router.c.
1849 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1850 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1851 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1852 lib/silccrypt/silchmac.c.
1854 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Assure that router cannot reroute the same channel message
1857 to the sender. Affected file silcd/packet_receive.c.
1859 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Made better checks that the channel message is not sent
1862 to the router it came from. Affected file is
1863 silcd/packet_send.c. Fixed memory leak too.
1865 * Announce informations for incoming router connection, but
1866 only after checking if it is replaced by backup router.
1867 Affected file silcd/packet_receive.c.
1869 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1871 * Fixed the backup resuming protocol to work in multiple
1872 router environment. Affected file silcd/server_backup.c.
1874 * Route packet only to one router in the function
1875 silc_server_packet_send_to_channel. Affected file is
1876 silcd/packet_send.c.
1878 * Fixed silc_server_send_notify_dest to set the broadcast
1879 flag. Fixed the silc_server_send_notify_topic to actually
1880 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1881 Affected file silcd/packet_send.c.
1883 * Changed the SFTP Filesystem interface. Changed the
1884 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1885 the filesystem operation function. The SilcSFTPFilesystem
1886 is now a context that is allocated by all filesystem allocation
1887 functions and it already includes the operations structure
1888 and filesystem specific context. It is given as argument
1889 now to the silc_sftp_server_start. This made the interface
1890 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1891 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1893 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Changed the backup router adding and getting interfaces
1896 in the server. The router that will be replaced by the
1897 specified backup router is now sent as argument. Affected
1898 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1901 * Added silc_net_addr2bin_ne to return the binary form of
1902 the IP address in network byte order. Affected files
1903 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1905 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Check for existing server ID in silc_server_new_server
1908 and in silc_server_connect_to_router_final and remove the
1909 old entry if it exists. Affected file silcd/packet_receive.c,
1912 * Send the channel message always to only one router, either
1913 in upstream or downstream. Affected file is
1914 silcd/packet_send.c.
1916 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Wrote the definition of the backup resuming protocol to the
1919 protocol specification.
1921 * Removed one redundant channel key generation from normal
1922 server during joining procedure. Removed one redundant
1923 channel key sending from server to router during joining
1924 procedure. Affected file silcd/command.c.
1926 * Made minor bugfixes to the backup router resuming protocol.
1927 Affected file silcd/server_backup.c, server.c.

1932 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1935 * Implemented the backup resuming protocol that is used to
1936 resume the primary router position in the cell after the
1937 primary router comes back online. Affected files
1938 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1939 and silcd/server_util.[ch].
1941 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * Sleep two (2) seconds after sending QUIT command to server.
1944 Affected file lib/silcclient/command.c.
1946 * Assure that if outgoing data buffer is pending do not force
1947 send any data. Affected file silcd/packet_send.c.
1949 * Assure that if outgoing data buffer is pending do not force
1950 send any data. Affected file lib/silcclient/client.c.
1952 * Implemented the backup router support when the primary router
1953 goes down. The servers and routers can now use the backup
1954 router as new primary router without loosing connectivity.
1956 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1959 in the server to indicate disabled entry. All data read
1960 from the connection will be ignored and no data is sent
1961 for entry that is disabled. Affected files are
1962 silcd/idlist.h, silcd/server.c.
1964 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Created SFTP client and server test programs in the
1967 lib/silcsftp/tests directory.
1969 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Implemented memory filesystem (virtual filesystem) for
1972 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1975 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Implemented the SFTP (SSH File Transfer Protocol) to the
1978 lib/silcsftp. It includes SFTP client and SFTP server
1981 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Moved lib/silccore/silcprotocol.[ch] to the
1984 lib/silcutil library.
1986 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1987 take variable argument list pointer as argument. Affected
1988 file lib/silcutil/silcbuffmt.[ch].
1990 * Added silc_buffer_set function that is used to set data
1991 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1992 Affected file lib/silcutil/silcbuffer.h.
1994 * Changed various routines in the core library to use the new
1995 silc_buffer_set instead of allocating new buffer only for
1998 * Added 64-bit value formatting and unformatting support to the
1999 silc_buffer_[un]format routines. Affected file is
2000 lib/silcutil/silcbuffmt.[ch].
2002 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2003 to includes/bitmove.h.
2005 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Fixed channel user mode saving in client library. Affected
2008 file lib/silcclient/command[_reply].c.
2010 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Defined the file transfer to the SILC Protocol. Added
2013 new packet type SILC_PACKET_FTP and defined File Transfer
2014 Payload. The mandatory file transfer protocol is SFTP
2015 (SSH File Transfer Protocol). Affected file in addition
2016 of the internet draft is lib/silccore/silcpacket.h.
2018 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2019 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2020 is used as part of backup router protocol when the primary
2021 router of the cell is back online and wishes to resume
2022 the position as primary router.
2024 * Redefined the MAC generation keys in the protocol. The
2025 same key is not used anymore in both direction. Both
2026 direction will now use different keys for sending and
2027 receiving. This fixes a potential security flaw. This
2028 change causes incompatibilities in the protocol.
2030 * Redefined also the MAC computation from the packet.
2031 An packet sequence number is now added to the MAC
2032 computation. This prevents possible replay attacks against
2033 the protocol. This change too causes incompatibilities
2036 Added `sequence' field to the SilcPacketContext to hold
2037 the current sequence number for the packet.
2039 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Added `created' field to the SilcIDListData in the file
2042 silcd/idlist.h to indicate the time when the entry was
2045 * Added `created' field to the SilcChannelEntry too. Affected
2046 file silcd/idlist.h.
2048 * Added `creation_time' aguments to all the announcement functions
2049 in the server. If it is provided then only the entries that
2050 was created after the provided time frame are actually
2051 announced. Affected file silcd/server.[ch].
2053 * The protocol says that the Channel ID's IP address must be
2054 based on the router's IP address. Added check for this in
2055 the silc_server_new_channel when processing incoming New Channel
2056 Payload. Affected file silcd/packet_receive.c.
2058 * Print out the correct version with --version in SILC client.
2059 Affected file irssi/src/silc/core/silc-core.c.
2061 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2063 * Fixed WHOWAS command to check for completnes of the client
2064 entry always, not just when the command is coming from client.
2065 Affected file silcd/command.c.
2067 * Added new function silc_server_packet_queue_purge to purge the
2068 outgoing data queue to the network. After the function returns
2069 it is guaranteed that the outgoing packet queue is empty.
2070 Affected file silcd/packet_send.[ch].
2072 * Purge the outgoing packet queue in the rekey protocol's final
2073 callback to assure that all rekey packets go to the network
2074 before quitting the protocol. Affected file silcd/server.c.
2076 * Added silc_client_packet_queue_parse as similar function as
2077 in server to the client library. The affected file is
2078 lib/silcclient/client.c.
2080 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Splitted silcd/server.c and created silcd/server_util.[ch]
2083 for utility functions.
2085 * Added new socket flag SILC_SF_DISABLED to indicate that the
2086 connection is open but nothing can be sent to or received from
2087 the connection. Affected file lib/silcutil/silsockconn.[ch].
2088 The checking for disabled socket is checked in the low level
2089 silc_socket_write and silc_socket_read functions.
2091 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * Allow only nicknames and channel names that fits into the
2094 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2096 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * When processing JOIN command reply in server check that if
2099 the channel exists in our global list we'll move it the local
2100 list. Affected file silcd/command_reply.c.
2102 * Fixed the check whether client is joined on the channel already
2103 in JOIN command. Affected file lib/silcclient/command.c.
2105 * Fixed the JOIN command reply to check whether the channel
2106 already exists. Affected file lib/silcclient/command_reply.c.
2108 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Added silc_ske_status_string to map the SKE error numbers
2111 to readable strings. The affected files are
2112 lib/silcske/silcske[_status].[ch].
2114 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Do not show the private channels on the WHOIS channel list
2117 as it is not allowed by the protocol. The affected file is
2120 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2122 * Assure that the packet length digged from the actual packet
2123 is something sensible in the silc_packet_decrypt_rest_special
2124 in lib/silccrypt/silcpacket.c.
2126 * Free and NULL the allocated pointer in silc_hmac_alloc if
2127 the HMAC allocation fails. The affected file is
2128 lib/silccrypt/silchmac.c.
2130 * Print the selected security properties to the log files in
2131 the server. Affected file silcd/protocol.c.
2133 * Add SKE's reference counter even if calling the completion
2134 callback manually. Otherwise it goes negative, although it
2135 does not cause any problems. The affected file is
2136 lib/silcske/silcske.c.
2138 * Remove the client entry with short timeout after giving the
2139 KILL command. Affected file lib/silcclient/command.c.
2141 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2142 case all found clients are already disconnected (WHOWAS would
2143 found them) in the server. Affected file silcd/command.c.
2145 * Update the last_receive (time of last data received) to be
2146 updated only when received private or channel message so that
2147 the idle time showed in WHOIS makes more sense.
2149 * Added boolean field `valid' in to the SilcClientEntry in the
2150 client library to indicate whether the entry is valid or not.
2151 This fixes the nickname change bug on channel when changing
2152 the nickname to be same than the old (like nick to Nick) the
2153 nickname formatter doesn't set the new nick anymore to Nick@host.
2154 Affected file lib/silcclient/idlist.[ch].
2156 * Now actually fixed the nickname changing on disconnection.
2157 Added new function silc_change_nick to the Irssi SILC Client.
2158 Affected file irssi/src/silc/core/client_ops.c,
2159 irssi/src/silc/core/silc-nicklist.[ch].
2161 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Check that the public key exists in the GETKEY command before
2164 trying to encode it. Affected file silcd/command.c.
2166 * Print some notifications on received public keys with GETKEY
2167 command in the Irssi SILC Client. Affected files are
2168 irssi/src/fe-common/silc/module-formats.[ch],
2169 irssi/src/silc/core/client_ops.c.
2171 * Use IDENTIFY command to resolve the server information in the
2172 GETKEY command instead of INFO command. Affected file
2173 lib/silcclient/command.c.
2175 * All command reply functions in the client library now calls
2176 the pending command reply callbacks even if an error has
2177 occurred. The server has done this a long time and now it was
2178 time to move the client library to this as well. Now all
2179 errors can be delivered back to the pending command reply
2180 callbacks if necessary. Affected files are
2181 lib/silcclient/command[_reply].[ch].
2183 * Change the nickname on disconnection back to the username
2184 because in reconnect the server will enforce it to it anyway.
2185 Affected file irssi/src/silc/core/silc-servers.c.
2187 * Fixed a config file parsing bug in the Irssi SILC client.
2188 Affected file irssi/src/silc/core/clientconfig.c.
2190 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * When printing the channel mode on JOIN, verify that the
2193 channel key and channel's HMAC are valid. Affected file
2194 irssi/src/silc/core/client_ops.c.
2196 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2199 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2200 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2202 * Removed channel key rekey task deleting from the function
2203 silc_server_save_channel_key. Affected file silcd/server.c.
2204 Added explicit timeout task context instead that is used to
2205 delete the task if we are registering a new task before the
2206 new task has elapsed.
2208 * When channel key rekey occurs the client library now saves
2209 the old channel key for a short period of time (10 seconds) and
2210 is able to use it in case some is still sending channel
2211 messages encrypted with the old key after the rekey. Affected
2212 file lib/silcclient/[idlist.h|client_channel.c].
2214 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Added check to the silc_server_new_id_real to not accept
2217 new ID if it is the sender's own ID. Affected file is
2218 silcd/packet_receive.c.
2220 * Assure that we do not announce ourself or the one we've
2221 sending our announcements when we're router and are announcing
2222 servers to our primary router. Affected file silcd/server.c.
2224 * Fixed silc_server_command_identify_check_client to assemble
2225 correct WHOIS packet. It send corrupted WHOIS packet and
2226 caused problem with router to router connections. Affected
2227 file silcd/command.c.
2229 Fixed also silc_server_command_whois_check the same way
2230 as for the IDENTIFY command.
2232 * Added new SilcIDListStatus to the server in the SilcIDListData
2233 structure. The status now includes the current status of
2234 the entry (like registered, resolved etc.). Affected file
2235 silcd/idlist.[ch]. Defined a bunch of different status types
2236 as well. This replaced the old boolean registered field as well.
2238 Added resolve_cmd_ident field to the SilcClientEntry structure
2239 too so that if the entry is for example being resolved so
2240 another command may attach to the same pending command reply
2241 without requiring to resolve the same entry again. This concept
2242 should optimize the WHOIS and the IDENTIFY resolving under
2243 heavy load by taking away unnecessary resolving for entries
2244 that are being resolved already.
2246 Added support for adding multiple pending commands for one
2247 command idenfier. Affected file silcd/command[_reply].[ch].
2249 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2250 before deleting the data. Otherwise the hash table will have
2251 freed data in comparison functions. Affected file is
2252 silcd/command_reply.c.
2254 * Fixed silc_idlist_replace_client_id to add the new entry to
2255 the cache with NULL nickname. Otherwise there will be invalid
2256 memory as the nickname after the nickname is freed. Affected
2257 file silcd/packet_receive.c.
2259 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2260 saved into wrong slots because the previous number of entries
2261 was not taken into account. Affected file silcd/idlist.c.
2262 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2264 * If we are router and we receive JOIN notify to a channel that
2265 does not have any users then notified client is marked as the
2266 channel founder, as it is it. The affected file is
2267 silcd/packet_receive.c
2269 * Added to the extended hash table API's table_del_*ext functions
2270 the destructor as argument too, so that the caller can decide
2271 which destructor to use or whether to use destructor at all.
2272 Affected file lib/silcutil/silchashtable.[ch].
2274 * Fixed ID Cache purging. It actually deleted the entries from
2275 the hash table after the data was freed. The hash table ended
2276 up comparing freed memory. The affected file is
2277 lib/silccore/silcidcache.c.
2279 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Fixed Irssi SILC client's KILL command's HELP syntax.
2283 * The USERS command now resolves the detailed user information
2284 if the userinfo field is missing. Affected file is
2285 lib/silcclient/command_reply.c.
2287 * Do not print error in silc_file_read if the read file does
2288 not exist. Just silently return NULL. Affected file is
2289 lib/silcutil/silcutil.c.
2291 * Fixed the silc_log_output to not wine about NULL filename
2292 and to not create some bogus " " filename. Affected file is
2293 lib/silcutil/silclog.c.
2295 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Fixed various printing bugs on the user interface in the
2298 Irssi SILC Client. Minor changes that were forgotten from
2301 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Fixed the configure.in.pre and the compilation and distribution
2304 environment to support the new autoconf 2.52. That version is
2305 now required to compile the CVS trunk.
2307 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2310 to generally parse user@fqdn format strings. Affected file
2311 lib/silcutil/silcutil.c.
2313 * Added nickname_format and nickname_force_format fields to the
2314 SilcClientParams structure. The first one defines the format
2315 for the nicknames that the library will enforce if the receives
2316 multiple same nicknames. The second one is boolean value and
2317 can be used to force the library to always enforce the format
2318 to the nicknames regardles whether there are multiple nicknames
2319 or not. This configurable formatting was employed to flexibly
2320 support accessing multiple nicknames from the user interface.
2321 The userinterface can now set the nicknames to what ever format
2322 they prefer. Affected file lib/silcclient/silcapi.h.
2324 Added function silc_client_nickname_format to the file
2325 lib/silcclient/idlist.c. It performs the nickname formatting.
2327 Added new field `hostname´ to the SilcClientEntry context.
2328 It holds the hostname of the client. Affected file is
2329 lib/silcclient/idlist.h.
2331 * Irssi SILC Client sets the nicknames in nick@hostn format.
2332 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2333 irssi/src/silc/core/silc-core.c.
2335 The WHOIS printing now also shows both the real nickname and
2336 the formatted nickname so that user knows how to access the
2337 user if there are multiple same nicknames cached. Affected
2338 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2339 printing formatting too to take the hostname now as a separate
2340 argument. The Affected file is
2341 irssi/src/fe-common/silc/modules-formats.[ch].
2343 * Changed the silc_client_get_clients_local to accept the formatted
2344 nickname as argument. It accepts the real nickname too but the
2345 formatted nickname can be used to find the true entry from
2346 multiple entries. Affected file lib/silcclient/silcapi.h and
2347 lib/silcclient/idlist.c.
2349 * Added nickname_format_parse field to the SilcClientParams.
2350 It is a callback function provided by the application to parse
2351 the nickname out of the formatted nickname string. The library
2352 calls it to get the nickname from the formatted string. Since
2353 the application generally knows better the format of the nickname
2354 string it parses it instead of the library, even though library
2355 encodes the formatted string. If the callback function is not
2356 provided then the library will use the string as is. The
2357 affected file is lib/silcclient/silcapi.h.
2359 * All the nickname strings passed to the client library in
2360 commands are now expected to be formatted nickname strings.
2361 If the command does not support the formatted nickname string
2362 it will assume that the sent string is the actual nickname.
2363 Affected file lib/silcclient/command.c.
2365 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Added public key authentication support to OPER and SILCOPER
2368 commands in the client library. Affected file is
2369 lib/silcclient/command.c.
2371 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Changed the get_auth_methdod client operation to be asynchronous.
2374 It can be async if the application resolves the authentication
2375 method from the server during the negotiation. Added new
2376 SilcGetAuthMeth completion callback that the application will
2377 call after resolving the authentication method.
2379 Added function silc_client_request_authentication_method that
2380 the application can use to resolve the authentication method
2381 from the server. Added also SilcConnectionAuthRequest callback
2382 that the library will call after the server has replied. The
2383 application can call this function if it does not know the
2384 current authentication method.
2386 Affected files are lib/silcclient/client.c and
2387 lib/silcclient/silcapi.h.
2389 * The Irssi SILC client now automatically resolves the authentication
2390 method incase any configuration information is not present (and
2391 currently there never is). The affected file is
2392 irssi/src/silc/core/client_ops.c.
2394 * Fixed public key authentication from the client library.
2395 Affected file lib/silcclient/protocol.c. Changed also the
2396 protocol specification about the public key authentication in
2397 the connection authentication protocol. The actual data to be
2398 signed is now computed with a hash function before signing.
2400 * Fixed the public key authentication from the server as well.
2401 Affected file silcd/protocol.c.
2403 * Removed the mlock()'s from the memory allocation routines.
2404 Affected file lib/silcutil/silcmemory.c. The ./configure does
2405 not check anymore for the mlock(). Affected file is
2408 * Fixed USERS command in server to allow the execution of the
2409 command for private and secret channels if the client sending
2410 the command is on the channel. Affected file silcd/command.c.
2412 * Fixed silc_client_get_clients_local to return the clients
2413 count correctly. It could return wrong value. Affected file
2414 lib/silcclient/idlist.c.
2416 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2419 types. The assembler optimizations seemed not to like 64-bit
2420 data types. The assmebler optimizations thus are now enabled
2421 also for BSD systems as opposed to only enable them for Linux.
2423 * Do not check for threads at all on BSD systems. Affected
2424 file configure.in.pre.
2426 * Removed -n and -h options from the Irssi SILC Client since
2427 they are not used in silc.
2429 * Fixed the prime generation to assure that the first digit
2430 of the generated random number is not zero since our conversion
2431 routines does not like number strings that starts with zero
2432 digit. If zero digit is seen the random number is regenerated.
2433 This caused some corrupted RSA keys when the zero first digit
2434 was met. Affected file lib/silcmath/silcprimegen.c.
2436 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Fixed WIN32 configuration in the ./configure script.
2439 Fixed to include xti.h on environments that has it.
2440 Patches by Carsten Ilchmann and andrew.
2442 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2444 * Changed the silc_id_create_client_id to be collision
2445 resistant. It is now assured that there cannot be created
2446 two same client ID's. I suspect that some weird bugs in
2447 the server were actually caused by duplicate Client IDs.
2448 Affected file silcd/serverid.[ch]. A router receiving
2449 new ID now also assures and informs the sending server
2450 if the ID caused collision.
2452 * Changed the silc_id_create_channel_id to also assure that
2453 there are no collisions.
2455 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Statement about ignoring the Mutual Authentication flag when
2458 performing rekey with PFS was a bit misleading. It is ignored
2459 if it was set in the initial negotiation, it cannot be even
2460 set in the rekey. Fixed in the ke-auth draft. Started the
2461 new versions of the protocol drafts in the doc/.
2463 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Fixed a bug in silc_client_command_identify_save when saving
2466 new channel information. The channel name was no duplicated
2467 and caused crash on exit. Affected file is
2468 lib/silcclient/command_reply.c.
2470 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Fixed the getkey command handling in the server. Send just
2473 empty OK reply to the sender if the key could not be fetched
2474 (but everything else was ok, like the key just was not available).
2475 Changed the public key parameter to optional in the protocol
2476 specs so that empty OK reply can be sent. Affected file
2479 Added a message to Irssi SILC client to tell to user if the
2480 server did not return a public key.
2482 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * Fixed a channel key regeneration bug. It registered new
2485 timeout tasks exponentially until all system resources were
2486 used. Affected file silcd/server.c.
2488 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Added the SILC Document generator to the scripts/silcdoc.
2491 It can be used to generate the Toolkit Reference Manual out
2492 of the source tree. Internally it will also use the RoboDoc
2493 generator now imported in util/robodoc.
2495 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Added couple of return's in rekey protocol if error orccurred
2498 during the protocol. The execution must be terminated.
2499 Affected file silcd/protocol.c. Also, terminate the protocol
2500 always with timeout.
2502 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * The client's Client ID was created initally from the wrong
2505 nickname (it could have been in format nick@host) in the
2506 silc_server_new_client. Affected file silcd/packet_receive.c
2508 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Added some SILC_LOG_ERROR's to various error conditions
2511 if client could not be added to ID cache. Affected files
2512 silcd/packet_receive.c and silcd/server.c.
2514 * When client's sock->user_data is freed, NULL also the
2515 client->router and client->connection pointers. Added check
2516 for these pointers being NULL to various places around the
2517 code. Affected file silcd/server.c.
2519 * Added client->data.registered == TRUE checks to various
2520 places around the code to assure that unregistered client's
2521 are not handled when it is not allowed. Affected file
2524 * Added `bool registered' fields to all
2525 silc_idlist_[server|client]_get_* routines to indicate whether
2526 the fetched client needs to be registered or not. Affected
2527 file silcd/idlist.[ch].
2529 * Add your own entry as registered to the ID cache in the
2530 server. Affected file server.c.
2532 * Fixed a bug in silc_server_new_server. The SilcServer was
2533 set as the new server's context instead of SilcServerEntry.
2534 This naturally caused some weird bugs.
2536 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Do not delete the channel rekey task when adding it
2539 for in silc_server_create_channel_key.
2541 * Changed the silc_server_create_channel_key to return
2542 TRUE or FALSE to indicate the success of the channel key
2545 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Fixed MSVC++ project files and added missing files to
2548 Makefiles under win32/.
2550 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Do not add TCP_NODELAY flag if the operating system
2553 does not have it defined. Affected files are
2554 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2556 * Fixed buffer overflow from Irssi SILC Client. Affected
2557 file irssi/src/fe-common/core/themes.c.
2559 * Fixed double free in client library in the file
2560 lib/silcclient/client.c when disconnecting from server.
2562 * Applied double free patch from cras to Irssi SILC client.
2563 Affected files irssi/src/core/[modules/expandos].c
2565 * Fixed the disconnection handling to Irssi SILC Client.
2566 The application must call silc_client_close_connection
2567 in ops->connect client operation in case of failure of
2568 the connection. Affected file is
2569 irssi/src/silc/core/client_ops.c.
2571 * Do not set sock->protocol to NULL in the function
2572 silc_client_close_connection after executing the protocol's
2573 final callback since the sock might not be valid anymore.
2574 Affected file lib/silcclient/client.c.
2576 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Do not enable SILC_THREADS if the linking with libpthread
2579 did not happen. Affected file configure.in.pre.
2581 * Added notion to protocol specification that server must
2582 verify the sent authentication payload with CMODE when
2583 setting the channel founder key. Implemented it to the
2584 server. Affected file silcd/command.c.
2586 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Added _EXTRA_DIST SILC distribution variable to the
2589 distributions file. It is used to conditionally add extra
2590 files or directories to the specific distribution. Affected
2591 files ./prepare, Makefile.am.pre and distributions.
2593 Removed the `_' from the start of the distribution names.
2596 * Added README.WIN32 for instructions to compile the Toolkit
2599 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Fixed a double free in disconnection in the server. Affected
2602 file is silcd/server.c.
2604 * Fixed the lib/silcske/groups.c to work now also with GMP
2605 MP library. The string conversion did not work when using
2606 specific base and the base is indicated in the string as well.
2608 * Created win32/ directory which now includes MSVC++ specific
2609 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2610 It will appear only in the toolkit distribution
2612 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Changed the key material distribution function in case when
2615 the hash output is too short. The data is now concatenated
2616 a bit differently than it used to. Made the change to the
2617 SKE protocol specification.
2619 * Added better GMP detection to configure.in.pre. A patch
2622 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Fixed a minor bug in SKE that might cause some problem on
2625 some platforms. Affected file lib/silcske/silcske.c.
2627 * Added the cookie checking for initiator in the SKE. It checks
2628 that the responder returns the sent cookie unmodified. The
2629 affected file is lib/silcske/silcske.c. Added new SKE
2630 error type INVALID_COOKIE that can be sent during the
2631 negotiation. Fixed some memory leaks as well.
2633 * Added the "invalid cookie" error message to Irssi SILC client's
2636 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2638 * Added `task_max' field to the SilcClientParams to indicate
2639 the maximum tasks the scheduler can handle. If set to zero,
2640 default values are used. Affected file lib/silcclient/silcapi.h.
2642 * Fixed memory leaks in silc_client_close_connection. Affected
2643 file lib/silcclient/client.c.
2645 * Added silc_client_del_client_entry to client library to free
2646 all memory of given client entry. Affected file is
2647 lib/silcclient/idlist.[ch].
2649 * Added new functions silc_client_del_channel and
2650 silc_client_del_server to delete channel and server entries.
2651 Affected file lib/silcclient/[silcapi.h/idlist.c].
2653 * Removed silc_client_del_client_by_id from silcapi.h.
2655 * Fixed the INFO command to return the server's own info
2656 correctly when querying by Server ID. Affected file is
2659 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Removed the non-blocking settings in WIN32 code in the
2662 silc_sock_[read/write] and added SleepEx instead. Affected
2663 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2664 of input data is now checked with FIONREAD and ioctlsocket.
2666 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Call silc_schedule_task_del_by_context in the
2669 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2670 Affected file lib/silccore/silcprotocol.c.
2672 * Call silc_protocol_cancel for active protocols in the
2673 silc_server_close_connection if the funtion
2674 silc_server_free_sock_user_data has not been called.
2675 Affected file silcd/server.c.
2677 * Generic tasks cannot be deleted using the del_by_fd
2678 task deleting function since generic tasks does not match
2679 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2681 * Added a notion to SILCOPER help file that the SILCOPER works
2682 only on router server, not on normal server.
2684 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Added for WIN32 support for the new scheduler as well.
2687 Affected file lib/silcutil/win32/silcwin32schedule.c.
2689 * Fixed the SHA1 implementation to work on various platforms.
2691 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2694 API. It is part of the scheduler now. Everything else is
2695 as previously but some functions has changed their names.
2696 Checkout the lib/silcutil/silcschedule.h for the interface.
2697 Updated all applications to use the new interface. Affected
2698 files are lib/silcutil/silcschedule.[ch].
2700 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Found a bug in the SKE implementation. The HASH value,
2703 specified by the protocol, was not computed correctly. The
2704 public key of the responder was not added to the computation
2705 even though it is mandatory. Affected file lib/silcske/silcske.c.
2706 This unfortunately causes incompatibilities with older
2707 clients and servers.
2709 * Added WIN32 specific network init and uninit functions:
2710 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2711 the Winsock2. Affected file lib/silcutil/silcnet.h and
2712 lib/silcutil/win32/silcwin32net.c.
2714 * Set the socket always to nonblocking mode on WIN32 after
2715 reading data or writing data. Affected file is
2716 lib/silcutil/win32/silcwin32sockconn.c.
2718 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Fixed various compilation problems under WIN32. Affected
2721 files lib/silcutil/win32/silcwin32thread.c and
2722 lib/silcutil/win32/silcwin32schedule.c.
2724 * Removed all _internal.h #includes from public header
2725 files. Internal headers must never be included from
2728 Removed also the lib/silcske/payload_internal.h file.
2730 * All include files that may be needed (public and some others
2731 included by the public headers) by application developers are
2732 now copied to the ./includes directory. It does not copy any
2733 internal headers. Affected file Makefile.defines.pre and all
2734 Makefile.am's under lib/ and subdirs.
2736 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Do not change the ~/.silc directory's permissions automatically.
2739 Affected file irssi/src/silc/core/clientutil.c.
2741 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Do not cancel the protocol in silc_server_close_connection
2744 it might cause recursion. Now cancelled in the function
2745 silc_server_free_sock_user_data. Affected file silcd/server.c.
2747 * Fixed the silc_server_remove_clients_by_server to regenerate
2748 the channel keys correctly finally. Added also new function
2749 silc_server_remove_clients_channels to actually do it.
2750 Affected file silcd/server.c.
2752 * Fixed the silc_server_new_channel to not crash by giving
2753 wrong router to the new channel. Affected file is
2754 silcd/packet_receive.c.
2756 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2759 which is given as argument to the silc_client_alloc now.
2760 It can be used to configure the client and set various parameters
2761 that affect the function of the client.
2763 * The USERS command in server did not check whether the channel
2764 is private or secret. Affected file silcd/command.c.
2766 * Added new argument to the USERS command in protocol specification.
2767 The USERS command now can take the channel name as argument
2768 as well. Added support for this in client and server and
2769 updated the protocol specs.
2771 * Completed the GETKEY command in client. It can be now used
2772 to fetch also servers public key not only some clients.
2773 Affected files lib/silcclient/command[_reply].c.
2775 * Added silc_client_get_server to return server entry by the
2776 server name. Affected files lib/silcclient/silcapi.h and
2779 * Redefined the IDENTIFY command in protocol specification to be
2780 more generic. It now can be used to query information about
2781 any entity in the SILC Network, including clients, servers and
2782 channels. The query may be based either the entity's name
2783 or the ID. Added support for this in both client and server.
2785 Affected files silcd/command.c and lib/silcclient/command.c
2786 and command_reply.c.
2788 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2789 the _from_client and _from_server functions. Affected file
2792 * Added silc_client_get_channel_by_id_resolve to the file
2793 lib/silcclient/silcapi.h to resolve channel information by
2794 its ID. Added also silc_client_get_channel_by_id that
2795 does not resolve it from the server.
2797 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Added SilcServerEntry context into the client library
2800 to represent one server. The INFO command now allocates
2801 these to save the resolved server info. For now on the
2802 client library will also keep information about servers,
2803 connected and resolved with INFO.
2805 The INFO command now allocates the SilcServerEntry context
2806 and saves the server info there. The COMMAND_REPLY in
2807 the INFO now returns the parameters to application in
2808 same order as defined in the protocol specification.
2810 The entries are cached in the client->server_cache.
2812 * The INFO command is now issued after received the Client ID
2813 from the server. Affected file lib/silcclient/client.c.
2815 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2816 to the application as the mode changer might be server.
2817 It is guaranteed that NULL is not returned anymore to the
2818 application. Affected file lib/silcclient/client_notify.c.
2820 The ID Type is now also passed to the application so that
2821 it can check whether the returned entry is SilcClientEntry
2824 Added new function silc_client_get_server_by_id to return
2825 the server entry by ID. Affected files are the
2826 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2828 * Do not create the channel in the Irssi SILC Client when issuing
2829 the JOIN command but when received the sucessful JOIN command
2830 reply. Otherwise the channel might get created even though we
2831 could not join it. The Affected file is
2832 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2834 * Fixed a channel joining bug in router. The router must also
2835 check the channel modes, invite and ban lists etc. when serving
2836 the JOIN command sent by normal server. Affected file is
2837 silcd/command.c. The router now resolves the client's
2838 information from the server who sent the JOIN command if it
2839 does not know it, and processes the JOIN command only after
2842 * Changed the SilcCommandCb to take new argument; void *context2.
2843 Affected file lib/silccore/silccommand.h
2845 The second argument in the command callbacks in the server now
2846 includes the SilcServerCommandReplyContext if the command was
2847 called as pending command callback from the command reply.
2848 Otherwise it is NULL. When called as pending the status of the
2849 command reply will be checked and if it was erronous the
2850 error will be sent to the original sender of the command.
2851 This way the client always receives the error messages even
2852 though the server was actually the one who received the error
2853 when it resent the command to router, for example. Affected
2854 files silcd/command[_reply].[ch].
2856 * Fixed sending WHOWAS command's error message to client if
2857 the requested client could not be found. It was missing.
2860 * Changed the CMODE and CUMODE commands reply arguments in the
2861 protocol specification. The Channel ID is now sent in both
2862 of the commands to identify the channel. Implemented this
2863 new feature to the client and server. Affected files
2864 lib/silcclient/command_reply.c and silcd/command.c.
2866 * Made better checks for invite and ban lists in the JOIN
2867 command in server. Affected file silcd/command.c.
2869 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * The server now performs the incoming host IP/DNS lookup
2872 using the silc_socket_host_lookup and thus does not block
2873 the server anymore. Affected file silcd/server.c.
2875 * Completed the multi-thread support for SILC Scheduler in
2876 the lib/silcutil/silcschedule.c.
2878 * Fixed the configure.in.pre to detect the pthread correctly
2881 * Fixed a deadlock in silc_task_queue_wakeup in the file
2882 lib/silcutil/silctask.c.
2884 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * Added new function silc_schedule_wakeup that is used in
2887 multi-threaded environment to wakeup the main thread's
2888 schduler. It needs to be used when a thread adds a new task
2889 or removes a task from task queues. After waking up, the
2890 scheduler will detect the task queue changes. If threads
2891 support is not compiled in this function has no effect.
2892 Implemented the wakeup mechanism to both Unix and WIN32
2893 systems. Affected files are lib/silcutil/silcschedule.[ch],
2894 lib/silcutil/unix/silcunixschedule.c and the
2895 lib/silcutil/win32/silcwin32schedule.c.
2897 * Added new function silc_task_queue_wakeup to wakeup the
2898 scheduler by the specified task queue. Affected file
2899 lib/silcutil/silctask.[ch].
2901 * The silc_socket_host_lookup_start now wakes up the scheduler
2902 after adding the timeout task. Affected file is
2903 lib/silcutil/silcsockconn.c.
2905 * The silc_socket_host_lookup is synchronous now if the threads
2906 support is not compiled in. However, the callback is still
2907 called asyncronously through the scheduler, anyway. Affected
2908 file lib/silcutil/silcsockconn.c.
2910 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2912 * Added new function silc_socket_host_lookup to perform
2913 asynchronous IP and FQDN lookups for the socket connection.
2914 Affected files lib/silcutil/silcsockconn.[ch].
2916 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2919 that may or may not compile the mutex support in.
2921 Changed the silc_mutex_alloc interface. It allocates the
2922 mutex now to the sent pointer and returns TRUE or FALSE.
2924 Affected file lib/silcutil/silcmutex.h.
2926 * Wrote the SILC Task Queue interface to support multi-threads.
2927 Affected file lib/silcutil/silctask.[ch].
2929 * Wrote the SILC Scheduler to support multi-threads. Affected
2930 file lib/silcutil/silcschedule.c.
2932 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2935 in lib/silcutil/win32/.
2937 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Defined SILC Mutex API and SILC Thread API and implemented
2940 them for Unix. Affected files are
2941 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2942 lib/silcutil/unix/silcunixmutex.c and
2943 lib/silcutil/unix/silcunixthread.c.
2945 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2947 * Fixed the silc_server_remove_clients_by_server's channel
2948 key re-generation. The hash table handling was incorrect
2949 and would not work with many channels. Affected file is
2952 * Fixed some memory leaks around the server code.
2954 * Rewrote the silc_server_get_users_on_channel to support IPv6
2955 based Client ID's. Affected file silcd/server.c.
2957 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2958 specification. However, a separate document must be written
2959 to define the detailed signing procedure and the payload
2960 associated with the flag. Defined the flag to the
2961 lib/silccore/silcchannel.h as well.
2963 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Changed the dynamic tables to static size tables in the
2966 lib/silccrypt/silchmac.c.
2968 * Removed GCC dependencies from the code. A patch by cras.
2970 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Do not show the error "Error receiving packet bla bla"
2973 in server if it really was not an error (-2 means that reading
2974 is pending). Affected file silcd/server.c.
2976 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Fixed a possible crash in silc_server_remove_clients_by_server
2979 in silcd/server.c. Fixed there also some memory leaks.
2981 * Fixed the silc_idlist_replace_client_id. It could replace
2982 wrong key in the hash table. Affected file silcd/idlist.c.
2984 * Do not check whether there are global users on the channel
2985 if the channel->global_users is FALSE. Affected functions
2986 silc_server_remove_from_one_channel and
2987 silc_server_remove_from_channels in silcd/server.c. Also,
2988 do not check if the removed client is local as we can be
2989 sure that global client was not removed from the channel
2990 and checking for global users is not needed.
2992 * The silc_server_remove_clients_by_server now re-generates
2993 the channel keys correctly for those channels that had
2994 clients removed from them. Affected file silcd/server.c.
2996 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2998 * Found the reason of random crashes in the server. We weren't
2999 ignoring the SIGPIPE signal (which can be sent in write())
3000 and it crashed the server. Affected file silcd/silcd.c.
3002 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Assure that sock->user_data is not NULL in the function
3005 silc_server_packet_send in silcd/packet_send.c.
3007 * Disconnect the remote connection if it could not be added
3008 to any ID lists in the server. The affected file is
3011 * Check in silc_server_packet_send[_real/dest] that the
3012 socket is not disconnecting and ignore the data if it is.
3013 Affected file silcd/packet_send.c.
3015 * Define inline to __inline on native WIN32 compilation.
3016 Affected file includes/silcwin32.h.
3018 * Added some explicit type casts for inline code since MSVC
3019 require them. Affected files lib/silcutil/silcbuffer.h,
3020 lib/trq/silcdlist.h and lib/trq/silclist.h.
3022 * Print warning in log files from now on if the packet
3023 decryption fails. Affected file silcd/server.c.
3025 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Changed the `say' client operation's interface to accept
3028 new `type' argument to indicate the type of the message sent
3029 by the library. The application may filter the library's
3030 messages according the type. The affected file is the
3031 lib/silcclient/silcapi.h.
3033 * Added two new functions to lib/silcclient/silcapi.h:
3034 silc_client_del_client and silc_client_del_client_by_id.
3035 Affected file lib/silcclient/idlist.c.
3037 * Moved the clientincludes.h from includes/ to silc/ and
3038 serverincludes.h from includes/ to silcd/.
3040 * The modes for the CMODE and CUMODE are now passed as
3041 uint32 for application with COMMAND_REPLY. The affected
3042 file is lib/silcclient/command_reply.c.
3044 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3046 * /WHOIS without arguments shows client's own information.
3047 Affected file lib/silcclient/command.c.
3049 * Changed PING to not accept any arguments. The specs
3050 says that client can ping only the connected server so
3051 requiring an argument is not needed. Affected file is
3052 lib/silcclient/command.c.
3054 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3056 * Fixed a fatal bug in private message sending and reception
3057 encryption and decryption when using private message keys.
3058 The implementation was incorrect and did not follow the
3059 specification. It causd that some of the message were
3060 lost since it did not use the sending and receiving keys
3061 as the protocol suggests. This has been fixed and will cause
3062 incompatibilities with older clients when sending private
3063 message encrypted with private message keys. Affected files
3064 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3065 and various other in Irssi SILC Client.
3067 Added `responder' boolean argument to the functions
3068 silc_client_add_private_message_key[_ske] to indicate when
3069 the key is added as responder or initiator of the key
3072 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Removed the silc_ske_check_version function and created
3075 a SilcSKECheckVersion callback. Added also a function
3076 silc_ske_set_callbacks that is now used to set all SKE
3077 callbacks. The callback functions are not given to
3078 the SKE functions anymore, but this function is used to
3081 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3083 * Added `silc_version' argument to the silc_client_alloc
3084 to define the version of the application for the library.
3085 The library will use the version string to compare it
3086 against the remote host's (usually a server) version
3087 string. Affected file lib/silcclient/silcapi.h
3089 * Added the KE protocol context to Key Agreement context
3090 in client library so that we can abort the SKE if it
3091 is in process when we get timeout. Affected file is
3092 lib/silcclient/client_keyagr.c.
3094 * Do not resolve the client ID forever if it returns in the
3095 first time that such client does not exist. This was done
3096 for example with private message. Affected file is
3097 lib/silcclient/client_prvmsg.c.
3099 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Do not add regex.h for WIN32. The affected file
3102 includes/silcincludes.h.
3104 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3105 not work yet 100%. It generates the DLL's automatically
3106 when compiling with --with-win32 under cygwin.
3108 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3110 * lib/contrib/regex.c is not compiled on WIN32.
3112 * Added silc_net_get_socket_opt function to the
3113 lib/silcutil/silcnet.h.
3115 * Added includes/silcwin32.h for WIN32 specific includes
3118 * Do not use ptime structure or any of the posix process
3119 functions on WIN32 in lib/silccrypt/silrng.c.
3121 * Added silc_gettimeofday to provide generic function
3122 for struct timeval on all platforms. Added the function
3123 to lib/silcutil/silcutil.h.
3125 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3128 library as they clearly belong there. As a plus side we
3129 can make the actual socket connection routines platform
3132 Added also new generic function silc_socket_read and
3133 silc_socket_write (that used to be silc_packet_[read/write].
3134 The implementation of these are platform specific.
3136 * Added WIN32 specific routines of silc_socket_[read/write]
3137 to lib/silcutil/win32/silcwin32sockconn.c.
3139 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * Added preliminary support for native WIN32 compilation under
3142 cygwin (using the -mno-cygwin option for GCC) to the
3143 ./configure.in.pre. The --with-win32 now prepares the
3144 compilation for native WIN32.
3146 * Rewrote the SILC Scheduler interface in the file
3147 lib/silcutil/silcschedule.h. The scheduler is now context
3148 based and does not have anymore any global static scheduler.
3149 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3150 and created lib/silcutil/win32 directory for WIN32 based
3153 * Added Unix specific network routines to the
3154 lib/silcutil/unix/silcunixnet.c and the old
3155 lib/silcutil/silcnet.c includes now only generic routines.
3157 Added WIN32 specific network routines to the
3158 lib/silcutil/win32/silcwin32net.c.
3160 * Added Unix specific utility functions from the
3161 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3163 * Added WIN32 SILC Scheduler to the file
3164 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3167 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3169 * Do not handle JOIN notify in the server if the target client
3170 is not registered (idata->registered == FALSE). The affected
3171 file is silcd/packet_receive.c.
3173 * Update the nickrec->founder in event_cumode in the Irssi SILC
3174 client. Affected file irssi/src/silc/core/silc-channels.c.
3176 * Fixed the CUMODE_CHANGE notify handling in the server when
3177 server and router are announcing their clients on channels.
3178 Now the mode changes are saved and notified correctly. The
3179 affected file is /silcd/packet_receive.c.
3181 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3182 They really did not replace the cache entry in the ID Cache.
3183 Now they do that. Affected file silcd/idlist.c.
3185 * Fixed the KICK notify handling in the Irssi SILC client to
3186 update the channel records so that the kicked client does not
3187 appear to be on the channel. The affected file is
3188 irssi/src/silc/core/silc-channels.c.
3190 * Always update the conn->current_channel when executing command
3191 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3193 * Fixed the KILL notify handling in Irssi SILC client to remove
3194 the killed client on all channels.
3196 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Fixed the silc_parse_command_line to remove extra spaces
3199 from the start and end of the arguments. Affected file is
3200 lib/silcutil/silcutil.c.
3202 * Cancel and free any active protocol in the function
3203 silc_server_close_connection. Affected file silcd/server.c.
3205 * Cancel and free any active protocol in the function
3206 silc_client_close_connction. Affected file is
3207 lib/silcclient/client.c.
3209 * Do not execute the KILL command for clients that are in
3210 history (ie. they are not in the network). Affected file is
3213 * Fixed KILL notify handling, client does not crash anymore.
3214 Affected file irssi/src/silc/core/silc-channels.c.
3216 * Reduced the default packet buffer size from 2048 to 1024 in
3217 lib/silccore/silcpacket.c.
3219 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3220 counter to the SKE context that is incresed when the SKE library
3221 performs async operation outside the library. If the outside
3222 process frees the SKE context and FREED status will be set
3223 and the library will detect after the sync operation that the
3224 libary is freed. The affected files are
3225 lib/silcske/silcske[_status].[ch].
3227 * Resolve the client entry information in the function
3228 silc_client_channel_message to assure that NULL pointer is not
3229 passed as client entry to the application. */
3231 * Fixed the task timeout calculation to assure that there is
3232 never negative timeouts. The affected file is
3233 lib/silcutil/silcschedule.c.
3235 * Fixed the channel user mode notification sending in server.
3236 It was sent point-to-point to the router (or to server by router)
3237 but it needs to be destined to a channel. The routines now
3238 supports sending the channel user mode notifys to the channels
3239 when announcing clients and channels. Affected files are
3240 silcd/server.c and silcd/packet_receive.c.
3242 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3243 It did not actually replace the old channel entry in the cache.
3244 Affected file lib/silcclient/client_notify.c.
3246 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Fixed a possible crash in silc_packet_send_prepare. It now
3249 assures always that there is enough space in the buffer and
3250 at the tail area of the buffer (for MAC).
3252 Fixed the inbound buffer reallocation in silc_packet_read.
3253 It was old code and did not handle the reallocation correctly.
3256 The affected file is lib/silccore/silcpacket.c.
3258 * Fixed buffer overflow in silc_parse_nickname in the file
3259 lib/silcutil/silcutil.c.
3261 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * make install generates new server keys only if there is not
3266 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3269 Added check that if the NOREPLY is set then we will not send
3270 the away message. This avoids infinite loop of away messages
3271 if both clients are away. The affected file is
3272 lib/silcclient/client_prvmsg.c.
3274 * Fixed client crash if /NICK was given without arguments.
3275 Affected file lib/silcclient/command.c.
3277 * Server does not send the invite list in INVITE command back
3278 to the client if the list was not altered. Added this notion
3279 to the protocol spec as well. Affected file silcd/command.c.
3281 Fixed possible crash in INVITE command by checking the
3282 value of silc_server_get_client_route command.
3284 * Fixed the INVITE notify type handling. The arguments are now
3285 taken in correct order and client does not crash. The affected
3286 file is irssi/src/silc/core/silc-channels.c.
3288 Removed the "Inviting xxx to channel" message from the
3289 client library away and let the application handle it.
3290 Affected file lib/silcclient/command.c. Added that message
3291 to Irssi SILC client's message formats.
3293 * Fixed CMODE command crash in client. It now checks the
3294 amount of arguments correctly and does not crash. The affected
3295 file is lib/silcclient/command.c.
3297 * Do not create new channel automatically in silc_channels_join
3298 but check whether the channel by that name already exists.
3299 Affected file irssi/silc/core/silc-channels.c.
3301 * Do not send the SERVER_SIGNOFF to router if the disconnected
3302 entity was the router. Affected file silcd/server.c.
3304 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3305 SILC client as it was missing from there.
3307 Added the handling of the KICK notify to the Irssi SILC client
3308 as it was missing. Added "you have been kicked" message to
3309 Irssi SILC client's message modules formats.
3311 Added the handing of the KILL notify to the Irssi SILC client
3312 as it was missing. Added the kill message module formats
3315 The affected file is irssi/src/silc/core/silc-channels.c.
3317 * The router did not save the channel mode the server announced.
3318 Affected file silcd/packet_receive.c.
3320 * Fixed a possible crash in INFO command in server. If the
3321 server did not provide the server info it crashed. Affected
3322 file silcd/command.c.
3324 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Fixed the GETKEY command in the server to check also the
3327 global list. Otherwise the GETKEY would not work correctly
3328 in normal SILC server. Affected file silcd/command.c.
3330 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Fixed GETKEY crash, it crashed if the command did not succseed.
3334 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3337 is now real and not just an macro interface to GMP.
3339 Removed the entire GMP from the source tree and imported new
3340 NSS MPI library instead. Reason for removing GMP is that it is
3341 extremely large and compiles extremely slow. The NSS MPI
3342 is only a few files and compiles in less than 10 seconds.
3343 The speed is also about the same as GMP. The MPI is imported
3344 to lib/silcmath/mpi.
3346 If the system has GMP installed we will still use the GMP.
3347 If it is not then the NSS MPI will be compiled.
3349 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Merged a long nickname (127 characters long) crash bugfix from
3352 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3354 * Merged a freed memory reference bugfix from Irssi CVS tree.
3355 Affected file irssi/src/core/commands.c.
3357 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Added the server's public key sving and verification to the
3360 server when performing the SKE. This was missing and the
3361 remote server's (or router's) public key was accepted without
3362 checking whether we have it previously or trust it at all.
3363 Affected file silcd/protocol.c.
3365 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Check in the silc_server_timeout_remote if protocol is active
3368 and make sure that the protocol's final callback is called so
3369 that all memory if freed. Affected file silcd/server.c.
3371 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * silc_server_whois_send_reply crashed the server if the nickname
3374 was 127 characters long. Affected file silcd/command.c.
3376 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3378 * Added sanity check to the silc_server_new_client. If the hostname
3379 is provided inside username then check that the provided hostname
3380 really is the same as the resolved one. If the hostname was not
3381 resolved then check it from the public key. Affected file is
3382 silcd/packet_receive.c.
3384 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3385 if the server disconnected us and the connection is not valid
3386 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3388 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3389 the library to the lib/silcutil/silcutil.[ch].
3391 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Close log file after open. Affected file
3394 lib/silcutil/silclog.c.
3396 * Check whether sock == NULL in silc_client_send_packet and return
3397 if it is. Affected file lib/silcclient/silcclient.c.
3399 * Check rec->entry == NULL in the Irssi SILC Client before
3400 sending the channel message. Affecte file is
3401 irssi/src/silc/core/silc-servers.c.
3403 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Merged a splitted window bugfix from Irssi CVS tree. The
3406 affected file is irssi/src/fe-text/textbuffer-view.c.
3408 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3409 It did not print nickname.
3411 * Improved the distributions system a bit.
3413 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3416 irssi/src/fe-text/gui-window.c.
3418 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3419 to in-active server. The affected file is
3420 irssi/src/silc/core/client_ops.c.
3422 * Resolve the client in USERS command reply if the entry does
3423 not have username resolved. The affected file is
3424 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3425 command to WHOIS command to really resolve stuff. The USERS
3426 is not used any more in any critical section so WHOIS can
3427 be used even though it might be slower than IDENTIFY.
3429 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3432 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Changed the protocol API a bit more consistent in the
3435 lib/silccore/silcprotocol.[ch].
3437 * Changed the following headers to ROBODoc format:
3439 lib/silccore/silcpayload.h
3440 lib/silccore/silcprotocol.h
3441 lib/silccore/silcsockconn.h
3443 All core library headers are now formatted.
3445 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Fixed a bug in Irssi SILC client; do not show that you are
3448 server/router operator if you really are not. Affected file is
3449 irssi/src/silc/core/client_ops.c.
3451 * Renamed silc_command_free_payload to silc_command_payload_free.
3452 Affected file lib/silccore/silccommand.h
3454 * Added silcmath.h to include the prototoypes of various routines
3455 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3458 * Changed the following headers to ROBODoc format:
3460 lib/silccore/silcchannel.h
3461 lib/silccore/silccommand.h
3462 lib/silccore/silcid.h
3463 lib/silccore/silcidcache.h
3464 lib/silccore/silcmode.h
3465 lib/silccore/silcnotify.h
3466 lib/silccore/silcpacket.h
3467 lib/silcmath/silcmath.h
3469 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added checking to the server code not to start the server if
3472 ciphers and stuff are not configured properly. Affected files
3473 silcd/serverconfig.[h] and silcd/server.c.
3475 * Changed the layout of the header files of the public interfaces
3476 in the SILC libraries. The new layout supports ROBODoc
3477 documentation tool (and some others) so that it is easy to create
3478 a library reference manual. All the other headers and source
3479 code must still follow the CodingStyle document. Also source
3480 code must not include these ROBODoc stuffs, only the headers.
3481 Furthermore, all public interface headers must now be named
3482 by using `silc' prefix, example: silcapi.h, silccipher.h.
3483 Some files were renamed due to this. All the other headers
3484 must not be used as public interfaces. I will update the
3485 CodingStyle document later. Changed following headers, so far:
3487 lib/silcclient/silcapi.h
3488 lib/silccore/silcauth.h
3489 lib/silccore/silcprivate.h
3490 lib/silccrypt/silcdh.h
3492 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Removed silc_client_packet_send_flush from the client library
3497 as it is not needed. Affected file lib/silcclient/client.[ch].
3499 * Added printing of message of unresolved authentication method
3500 to the Irssi SILC client. Added it to the module formats.
3501 Removed the same message from the client library.
3503 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Added new distribution feature, DISTLABEL. Every distribution
3506 can define own preprocessor label that can be used in the
3507 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3508 file distributions, acconfig.h.pre and prepare.
3510 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Added Makefile.defines_int to include the actual definitions
3513 for Makefile.defines.in. Tested the new distribution system,
3514 created distributions and tested installation.
3516 * Added AWAY message printing to the Irssi SILC client. Added
3517 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3519 * Added SCONNECT command to call the SILC's CONNECT command.
3520 Cannot use CONNECT directly since Irssi uses that internally.
3521 Affected file irssi/src/silc/core/silc-servers.c.
3523 Added ACTION local command. It is same as ME command but takes
3524 the channel as mandatory argument.
3526 Rewrote some of the Irssi's help files to suite for SILC
3529 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Added Makefile.defines[.in] that should for now on be included
3532 in all Makefile.am file in the source tree. That file includes
3533 all common compilation definitions for SILC source tree.
3535 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Minor changes to the ./prepare script to change the package
3538 name according the distribution name to the configure.in.
3540 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Created new distribution system. Added file `distributions'
3543 that defines all the distributions that can be created out of
3544 the SILC source tree. The ./prepare script now reads that
3545 file to determine how to prepare the distributions. The
3546 first argument to the ./prepare is the name of the distribution
3547 and second is the version of the distribution. If given
3548 without arguments it creates the default (toolkit) distribution
3549 with the default version (defined in ./prepare).
3551 All Makefile.am files that are subject to the distributions
3552 are now named as Makefile.am.pre. These are ./Makefile.am
3553 and lib/Makefile.am. Others may be changed later.
3555 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Added invite list, ban list, some key management and connection
3558 error message printing to module formats in the Irssi SILC client.
3560 * Added new silc_client_set_away_message to set the away message
3561 that is back to the person who sent private message. The
3562 affected file lib/silcclient/silcapi.h and the
3563 lib/silcclient/client_prvmsg.c.
3565 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Fixed the private message sending in the Irssi SILC client,
3568 added local command KEY to the Irssi SILC client.
3570 Added key management and key agreement message formats to the
3571 irssi/src/fe-common/silc/module-formats.[ch].
3573 Added USERS (alias WHO) printing, server/router operator
3574 indication and LIST command printing to the module formats.
3576 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Fixed channel joining notify handling, cumode notify handling
3579 from Irssi SILC client.
3581 * Added SILC specific module-formats to the Irssi SILC client so
3582 that SILC specific message hilighting, colors etc is possible.
3583 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3585 Added channel mode, channel user mode, actions, notices,
3586 whois and whowas printing to the the module-formats.c.
3588 * Fixed a bug in channel deletion in the server. The channel
3589 is not left to the cache even if the channel founder auth mode
3590 is set when there are no users anymore on the channel. Affected
3591 file silcd/server.c.
3593 * The silc_net_localhost now resolves the entire hostname including
3594 the domain name. Affected file lib/silcutil/silcnet.c.
3596 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Changed the ask_passphrase client operation to be ascynchronous.
3599 It has now a completion callback and a context that the
3600 application must call after it has got the passphrase from
3601 the user. Affected files lib/silcclient/silcapi.h,
3602 lib/silcclient/protocol.c, lib/silcclient/command.c and
3605 Added SilcAskPassphrase callback that the application calls
3606 to deliver the passphrase to the library.
3608 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3609 The public key verification and especially a certificate
3610 verification is asynchronous procedure.
3612 Added new SILC_SKE_STATUS_PENDING status to indicate the
3613 request is pending and a callback will be called to finalize
3616 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3617 indicate that remote end did not send its public key (or
3618 certificate), even though we require it. Added check for this
3619 condition in the SKE. This was a security bug, now fixed.
3621 Defined new SilcSKEVerifyCbCompletion callback that is called
3622 when the verification process is completed.
3624 The affected files lib/silcske/silcske_status.h and
3625 lib/silcske/silcske.[ch].
3627 * Changed the verify_public_key client operation to be async
3628 as well. Defined SilcVerifyPublicKey callback that is used to
3629 indicate the success of the public key verification process.
3631 Changed the server and client to use the new async client
3634 * Changed the Irssi SILC client's internal scheduler to be called
3635 twice as many times as it used to be. As a result the client
3636 should be a bit faster now. Affected file is
3637 irssi/src/silc/core/silc-core.c.
3639 * Added support to Irssi SILC client of asynchronous public key
3640 verification and passphrase inquiry. Affected file is
3641 irssi/src/silc/core/silc-core.c.
3643 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Do not say "You have left channel %s" in client library.
3646 Moved it to the application. Affected files are
3647 lib/silcclient/command.c and silc/client_ops.c.
3649 * Fixed silc_client_get_clients. Command context was not
3650 duplicated and was freed memory in the callback. Affected
3651 file lib/silcclient/idlist.c.
3653 * Do not say "you are now talking..." on JOIN command in the
3654 client library. The appliation must handle it.
3656 * Do not say ".. changed topic to" in command reply in the
3657 client libary. The application must handle it.
3659 * Fixed TOPIC command sending in the client library.
3661 * Fixed a memory leak in silc_client_command_free in the file
3662 lib/silcclient/command.c.
3664 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Imported a modified version of Irssi client to the source tree.
3667 The Irssi will be used to create a new client called
3668 Irssi SILC. Imported to irssi/.
3670 Added silc_core_init_finish function to the Irssi. Affected
3671 file irssi/configure.in.
3673 A lot changes in the Makefile.ams around the irssi tree.
3675 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Do not rehash if the new size is same as the old size of the
3678 hash table, in the silc_hash_table_rehash*. The affected file
3679 lib/silcutil/silchashtable.c.
3681 * Replaced hash_table_del_by_context calls from the server
3682 (when channel->user_list and client->channels) to the
3683 hash_table_del as it is sufficient and faster.
3685 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Added silc_hash_table_list, silc_hash_table_get and the
3688 SilcHashTableList structure to provide an alternative way to
3689 traverse the hash table. The affected files are
3690 lib/silcutil/silchashtable.[ch].
3692 * Changed the server's idlist routines to use the hash table
3693 routines to optimize the code.
3695 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Replaced the client entry's `channel' list and channel entry's
3698 `user_list' list to hash tables for optimized lookup. Changed
3699 the code to use the hash table interface around the code.
3700 Affected file lib/silcd/idlist.[ch].
3702 * Added `auto_rehash' boolean argument to the function
3703 silc_hash_table_alloc to indicate whether the hash table should
3704 auto-rehash when it thinks is appropriate time. It will
3705 increase the hash table size if the there is twice as much
3706 entries in the table than the size of the table, and will
3707 decrease the size if there are twice as less entries than
3708 the size of the table.
3710 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3714 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * silc_idcache_purge_by_context deletes the entry now by context
3717 as it is supposed to do. Affected file lib/silccore/idcache.c.
3719 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3720 client is not anymore valid (WHOWAS givens the info) and not
3721 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3723 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Removed the `data' and `data_len' arguments from the ID Cache
3726 interfaces and added `name' argument. ID Cache does not handle
3727 anymore the binary data only a names associated with given ID.
3729 * When hashing a Client ID with silc_hash_id the entire ID is
3730 not hashed anymore, instead only the hash of the Client ID is
3731 hashed. This way we can access the Client ID from the cache
3732 with Client ID but with the hash of the ID (which is a hash of
3733 the nickname) as well without any difference in performance.
3735 Added also silc_idcache_find_by_id_one_ext to do one on one
3736 searching when we have the actual ID. Added also function
3737 silc_hash_client_id_compare. The affected files are
3738 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3740 * When hashing the name associated with a ID it is always done
3741 in lowercase. This way we can access the cache without worrying
3742 about case-sensitivity, even though, for example nicknames are
3745 * Fixed a bug in server with channel message sending. It put
3746 wrong ID type as destination ID. The affected file
3747 silcd/packet_send.c.
3749 * silc_idcache_del_by_context now deletes from all hash tables
3750 by context. Affected file lib/silccore/idcache.c.
3752 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Changed the client library to use the new ID Cache interface.
3755 Changes around the source tree.
3757 * Added silc_hash_table_rehash_ext to rehash with specific
3758 hash function. Affected file lib/silcutil/silchashtable.[ch].
3760 * Added silc_hash_string_compare to compare two strings in the
3761 hash table. Affected file lib/silcutil/silcutil.[ch].
3763 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Added new function silc_idcache_del_by_context into the
3766 lib/silccore/idcache.[ch].
3768 * Changed the server's ID list routines to use the new ID Cache
3769 interface. Changes around the source tree.
3771 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Added silc_hash_table_del[_by_context]_ext functions in to the
3774 lib/silcutil/silchashtable.[ch].
3776 Removed silc_hash_table_find_all* routines and added new
3777 silc_hash_table_find_foreach to replace them.
3779 Added silc_hash_table_replace_ext function as extended
3780 replacing function. Separated the simple hash table interface
3781 from the extended hash table interface in the file
3782 lib/silcutil/silchashtable.h.
3784 * Fixed minor bugs and changed it to use some of the new
3785 hash table functions in lib/silccore/idcache.c
3787 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Added new function silc_hash_table_find_all to return all keys
3790 in the hash table by the specified key. As the hash table is
3791 collision resistant it also makes it possible to have several
3792 duplicate keys in the hash table. This function may be used to
3793 find all of the keys from the hash.
3795 Added user_context arguments to the SilcHashFunction,
3796 SilcHashCompare and SilcHashDestructor to deliver user specified
3799 Added new fuctions silc_hash_table_find[_all]_ext to do
3800 extended lookup with specified hash and compare functions and
3801 specified user contexts.
3803 Added new function silc_hash_table_add_ext to add the key
3804 with specified hash function and user context.
3806 Added new function silc_hash_table_foreach to traverse all
3807 entrys in the hash table. Added SilcHashForeach callback
3810 Added new function silc_hash_table_del_by_context to delete
3811 the entry only if the context associated with the key matches.
3813 Affected files are lib/silcutil/silchashtable.[ch].
3815 * Removed silc_hash_[server/client/channel]_id and added just
3816 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3817 silc_hash_id_compare to compare two ID's using as the hash table
3818 comparison function. Added also silc_hash_data to hash
3819 binary data and silc_hash_data_compare to compare it.
3821 * Removed silc_idlist_find_client_by_hash as it is not needed
3822 anymore. Affected file silcd/idlist.[ch].
3824 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3825 to use internally the SilcHashTable. The new ID Cache is a lot
3826 faster than the old one. Some of the ID Cache interface was also
3827 rewritten and obsolete and stupid functions were removed.
3829 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Added entry_count field to the SilcHashTable to keep the number
3832 of the entries in the table. Implemented the function
3833 silc_hash_table_rehash. Added new function
3834 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3836 Fixed a minor bug in silc_hash_table_free.
3838 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3839 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3840 into the lib/silcutil/silcutil.[ch].
3842 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Implemented a collision resistant hash table into the
3845 lib/silcutil/silchashtable[ch]. See the header and the source
3846 for the SilcHashTable API.
3848 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Merged dotconf version 1.0.2 into lib/dotconf.
3852 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Do not compile anything in lib/silcsim/* if the SIM support
3855 is not enabled. The tree should now compile without problems
3858 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Compiled the SILC under cygwin. Compiled and tested briefly
3861 without problems. More tests needed. The SIMs didn't compile
3864 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3866 * Fixed possible crash in silc_get_username in the
3867 lib/silcutil/silcutil.c.
3869 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Fixed a va_arg in silc/client_ops.c.
3873 * Oops, RC5 routines were named AES and caused some problems
3874 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3876 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Added new SilcIDIP structure into the lib/silccore/id.h and
3879 replaced the old `ip' fields from all SILC ID's to that type.
3880 This is a step towards IPv6 support.
3882 The silc_id_get_len takes now the ID as an extra argument.
3883 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3884 both IPv4 and IPv6 based ID's.
3886 The affected files are lib/silccore/id.[ch] and other files
3887 around the tree using these routines.
3889 * Removed the ID length arguments in server from various
3890 silc_server_send_notify_* routines -> they are not needed
3893 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * Fixed memory leak in silc_encode_pem_file in the file
3896 lib/silcutil/silcutil.c.
3898 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Check minor version as well in the SKE. Affected files are
3901 silcd/protocol.c and lib/silcclient/protocol.c.
3903 * Added --identifier option to the server so that an identifier
3904 can be when creating the public key for the server. Affected
3905 file is silcd/silcd.c.
3907 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3908 lib/silccrypt/silcpkcs.c.
3910 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Register default ciphers and stuff when using -C option with
3913 the server. Affected file sildc/silcd.c.
3915 * Put back the servers public key filename format, it is better
3916 than the new one. For now, the client keys are saved with the
3917 new filename format. The affected file silc/client_ops.c.
3919 * Implemented the Cipher API for the rest of the ciphers that
3920 did not implement it or implemented it the wrong way.
3922 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Register default ciphers and stuff when using the -S option
3925 in the client. Affected file silc/silc.c. Same also when
3926 creating new key pair with -C option.
3928 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Fixed the silc_verify_public_key client operation function to
3931 save the public keys differently. The fingerprint is now
3932 used as filename and not the hostname. This way also the
3933 client keys are saved uniquely and not with hostnames. The
3934 affected file is silc/client_ops.c.
3936 * Trimmed the silc_hash_fingerprint function to remove extra
3937 whitespaces from the end of the fingerprint. The affected
3938 file is lib/silccrypt/silchash.c.
3942 * Added silc_cipher_register_default function to register all
3943 default ciphers. It can be used when configuration files
3944 does not exist and the application does not want any specific
3945 ciphers in any specific order.
3947 The SilcDList is now used as silc_cipher_list dynamically
3948 allocated cipher list. Removed the static list all together
3949 and now all ciphers must be allocated to the dynamic list.
3950 The silc_cipher_alloc routine was changed to check only the
3953 All silc_cipher_* routines that used to return int returns
3956 The affected files lib/silccrypt/silccrypt.[ch].
3958 * The same thing was done to silc_hash_* as for silc_cipher_*
3959 routines. Affected files lib/silccrypt/silchash.[ch].
3961 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3962 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3963 Added also silc_pkcs_[un]register[_default] functions.
3964 Removed the data_context from the PKCS API.
3966 * Added silc_hmac_register_default function to register default
3967 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3968 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3969 to unregister all hmacs at once.
3971 * Register the default ciphers, hash functions, PKCSs and HMACs
3972 if client's configuration file does not exist. The affected
3975 * The client did not load the hash functions from the SIM
3976 modules at all. Added support for this. Affected file is
3977 silc/clientconfig.c.
3979 * When decoding public key with silc_pkcs_public_key_decode, check
3980 the supported algorithm only if PKCS are registered. Affected
3981 file lib/silccrypt/silcpkcs.c. The same was done with the
3982 silc_pkcs_private_key_decode.
3984 * Fixed the SILC List routines to keep the list always in order.
3985 It used to change the list's order when traversing the list but
3986 not it preserves the order. Affected file lib/trq/silclist.h.
3988 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Added the client library to use the SilcSocketConnection's
3991 reference counter (by silc_socket_dup) to prevent the bug that
3992 the socket object may be freed underneath async operation.
3994 * The name resolv library checking fixes in the configure.in.pre.
3997 * Created new version of the protocol drafts for future
3998 development. The -03 drafts are the ones that will be changed
3999 in the trunk now and the -02 will remain as they are.
4001 * Send list of CUMODE notifys to the router when announcing
4002 the channel users to the router. Affected file silcd/server.c.
4003 If the router receiving channel founder CUMODE for a channel
4004 that already has channel founder it will send CUMODE notify
4005 to the sender to remove the channel founder rights from the
4006 announced client. Affected file silcd/packet_receive.c.
4008 * The CUMODE notify may now use Server ID as well as the entity
4009 who changes the mode. Updated protocool specs.
4011 * Updated INSTALL and README files.
4013 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * New web pages in the http://silc.pspt.fi. The pages was
4020 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Implemented the [DenyConnectin] config section in the server.
4023 Added silc_server_config_denied_conn to check whether incoming
4024 connection is denied. Affected file silcd/serverconfig.[ch].
4026 * Do not check the ports when checking the incoming configuration
4027 data if the port is 0, meaning any. Affected file is
4028 silcd/serverconfig.c.
4030 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Fixed buffer overflow in silc_string_compare in the file
4033 lib/silcutil/silcutil.c.
4035 * Fixed double free in silc_server_command_leave in the file
4038 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Fixed the version checking in the server. Affected file is
4043 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Fixed the configuration data fetching when accepting new
4046 connections in the server. Affected file silcd/server.c.
4048 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Added `sender_entry' argument to the function
4051 silc_server_packet_relay_to_channel so that we can check
4052 whether some destination actually belongs to the same route
4053 the sender belongs (ie, we must not resend the packet to the
4054 sender). Affected file silcd/packet_send.[ch].
4056 * Added `servername' field to the SilcClientEntry in the server
4057 to hold the name of the server where client is from. Affected
4058 file is silcd/idlist.h.
4060 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Moved the channel message encrypting in the router betwen
4063 router connections from silc_server_channel_message to the
4064 silc_server_packet_relay_to_channel since we want to check
4065 whether we have anybody channel before encrypting anything.
4066 Affected files silcd/packet_[receive/send].c.
4068 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Fixed the [AdminConnection] server config section to support
4071 multiple entries. Affected file silcd/serverconfig.c.
4073 * Added support into the server to check the validity of the
4074 incoming connection before executing any KE or authentication
4077 * The connection configuration is now saved to the KE and
4078 connection auth protocol contexts and not fetched anymore in
4079 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4081 * The local hosts listenning address and port is also resolved
4082 now when starting the server. We want to have the socket object
4083 to include the real address and port for the listener. Added
4084 new function silc_net_check_local_by_sock into the files
4085 lib/silcutil/silcnet.[ch].
4087 * Fixed a broadcast bug in server -> do not broadcast if we
4090 * Fixed a routing bug. Do not route broadcast packets ever.
4091 Broadcast packets must be processed always and not routed since
4092 they may be destined to some other host than yourself and thus
4093 would get routed without no good reason. Affected file is
4096 * Added function silc_server_config_is_primary_route to check
4097 whether primary router connection has been configured (a router
4098 configuration that we are initiating). If there is not, we
4099 will assume that there is only two routers in the SILC network
4100 and we will use the incoming router connection as our primary
4101 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4103 * Changed the order of the broadcasting. Broadcast _after_ the
4104 packet has been processed not before. Affected file is
4107 * Fixed a [ClientConnection] parsing bug. The port was never
4108 parsed correctly thus resulting to port 0. Affected file
4109 silcd/serverconfig.c.
4111 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4112 argument and did not set the broadcast packet flag. Affected
4113 file silcd/packet_send.c. Fixed same bug in the function
4114 silc_server_send_notify as well.
4116 * If we receive NEW_ID packet for our own ID in the server, ignore
4119 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Removed the nickname from the Private Message Payload.
4124 Updated the code and the protocol specs.
4126 * Updated protocol specs for submitting to the IETF.
4128 * Tweaked the Random Number Generator a bit. Affected file
4129 lib/silccrypt/silcrng.c. Exported a new function
4130 silc_rng_[global]_add_noise which can be used to add more
4133 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Do not parse packets with different timeout when protocol
4136 is active -> may cause problem with rekey. Affected file
4139 * When server receives signoff notify it must not create
4140 new channel key if the client is on any channels since the
4141 sender of the signoff notify will create it.
4143 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Added printing of error messages during SKE protocol from the
4146 failure packet sent by server during SKE. Affected file
4149 * Removed the client's failure_callback handling with timeout
4150 and handle it immediately when received.
4152 * The SKE library returned wrong type in SUCCESS and FAILURE
4153 packets. They must be 32 bit MSB not 16 bit MSB.
4155 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Ok, rewrote the logic of the re-key and now it seems to work.
4158 I tested it on high traffic with frequent re-keys without
4159 problems. Added hmac_receive (and renamed hmac to hmac_send)
4160 in SilcClientConnection in lib/silcclient/client.h and
4161 in SilcIDListData in silcd/idlist.h. Also, removed the
4162 SilcPacketParserContext's cipher and hmac fields as they are
4163 not needed anymore and actually caused some problems when
4164 the ciphers and hmac's changed underneath the packet parser.
4166 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * If re-key protocol is active then process the incoming packets
4169 synchronously since we must assure that icoming packets encrypted
4170 with the old key is processed before the new keys is set to
4171 use. This is true other packets than for REKEY packets.
4172 Affected file silcd/server.c. The same was done to client library
4173 as well, affected file lib/silcclient/client.c.
4175 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Fixed bug in client and server to accept the force send if
4178 the packet is send from silc_[server/client]_packet_process
4179 function. Otherwise the packets are never delivered, oops.
4181 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Disable force sending of packets when REKEY protocol is active.
4184 We must assure that no packet is sent directly when rekey is
4185 performed. All packets must be sent through packet queue.
4186 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4187 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4188 function is silc_[server/client]_packet_send_real to check
4191 * Replaced the SIM paths from example config files to
4192 /usr/local/modules. Also, make install creates now
4193 /usr/local/silc/logs directory to hold all the SILC server
4196 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Made the configure.in.pre work on Solaris. Patch by salo.
4200 * Made all ciphers compatible with non-x86 machines. Defined
4201 CBC mode macros into lib/silccrypt/ciphers_def.h.
4203 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Fixed the make install.
4207 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * When MAC computation fails the silc_packet_decrypt returned 0
4210 even though it was supposed to return -1. Fixed this. The
4211 affected file is lib/silccore/silcpacket.c.
4213 * Do not replace the config files in /etc/silc (in make install)
4214 if they already exist. Affected file ./Makefile.am.
4216 * Do not send re-key packets immediately but through packet queue.
4217 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4219 * Changed silc_net_check_host_by_sock to return FALSE if the
4220 IP/DNS could not be resolved. Though, it returns the IP address
4221 now even if it could not resolve it (but returns also FALSE).
4222 Affected file lib/silcutil/silcnet.[ch].
4224 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Added silc_pkcs_decode_identifier to decode the public key's
4227 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4228 Added also silc_pkcs_free_identifier. Added also new context
4229 SilcPublicKeyIdentifier.
4231 * Added -S option to the silc client. It is used to dump the
4232 contents of the specified public key file.
4234 * Changed the PKCS api to return the public key length when
4235 setting the public key.
4237 * Fixed a fatal bug in the public and private key file loading.
4238 Affected file lib/silccrypt/silcpkcs.c.
4240 * Execute the packet parsing for client with zero (0) timeout
4241 if the protocol is active. Affected file silcd/server.c.
4243 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Made the key generation options to the silcd program. Added
4246 -C option, equivalent to client's option.
4248 * Added new [ServerKeys] config section to the server. It
4249 configures the server's public and private key.
4251 * Defined generic Public Key Payload into the protocol
4252 specification to send specific type of public keys and
4255 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4256 public key or certificate.
4258 * Implemented the GETKEY command to the server and to the
4259 client library and on user interface.
4261 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Made preliminary `make install' work.
4265 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Added SilcServerRekey context into silcd/idlist.h.
4269 * Added the PFS support as defined in the specification to the
4270 SKE protocol. Affected files lib/silcske/*.c.
4272 * Added `ske_group' field to the SilcServerRekey context to hold
4273 the number of the SKE group that is used with PFS in re-key.
4274 Affected file silcd/idlist.h.
4276 * Added PFS re-key support to the server. Affected file is
4279 * Added silc_protocol_cancel to cancel execution of the next
4280 state of the protocol. Affected file is
4281 lib/silccore/silcprotocol.[ch].
4283 * Added the re-key support with and without PFS to the client
4284 library. Re-key is performed once in an hour, by default.
4286 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4287 Added silc_client_rekey_callback and silc_client_rekey_final.
4288 Affected files are lib/silcclient/protocol.[ch] and
4289 lib/silcclient/client.[ch].
4291 * Removed the `hmac_key' and `hmac_key_len' fields from the
4292 SilcClientConnection structure; not needed. Affected file is
4293 lib/silcclient/client.h.
4297 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * Do not ask whether user wants to use the negotiated private key
4300 for private messages, just use it. Affected file is
4301 silc/local_command.c.
4303 * Added `send_enc_key' and `enc_key_len' fields to the
4304 SilcIDListData structure since they are needed in the re-key
4305 phase. Affected file is silcd/idlist.[ch].
4307 * Implemented the simple re-key protocol into the server.
4308 Affected files silcd/server.c and silcd/protocol.[ch]. The
4309 re-key will be performed once in an hour, by default.
4311 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4312 Added silc_server_rekey, silc_server_rekey_callback and
4313 silc_server_rekey_final.
4315 * Removed Tunneled flag from the protocol. Updated the code
4316 and the specifications.
4318 * Adde `pfs' field to the SilcIDListData to indicate whether
4319 the PFS is to be performed in the re-key. Affected file is
4322 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4325 int64 of at least the xintXX size. If void * is less that 4
4326 bytes uint32 * will be used. Defined bool as boolean.
4328 * Changed _ALL_ unsigned long and unsigned int to uint32,
4329 unsgined short to uint16 in the source tree.
4331 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4332 not handle clients that has entry->data.registered == FALSE.
4333 They are not in the network anymore. Affected file is
4336 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Implemented the sending of the SERVER_SIGNOFF notify in the
4339 server. Affected file is silcd/server.c.
4341 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4342 Added also silc_notify_payload_encode_args into the
4343 lib/silccore/silcnotify.[ch].
4345 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4346 Affected file silcd/packet_receive.c.
4348 * Implemented the SERVER_SIGNOFF notify handling in the client
4349 library. Affected file lib/silcclient/client_notify.c. Also,
4350 implemnted the printing of the SERVER_SIGNOFF info to the
4351 application. Affected file silc/client_ops.c.
4353 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4354 if the deleting was successful. Affected file silcd/idlist.[ch].
4356 * Added support for public key authentication in the connection
4357 authentication protocol in the client library. Affected file
4358 lib/silcclient/protocol.c.
4360 * Changed the server's silc_idlist_get_clients_by_* interface
4361 to support already allocated array so that new entries may be
4362 added to pre-allocated array. Affected file silcd/idlist.[ch].
4363 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4364 and command replies.
4366 * All command reply functions in the server now calls the
4367 pending command callback even if error occured. This way the
4368 error will be delivered to the client as well. Affected files
4369 silcd/command.c and silcd/command_reply.c.
4371 * Fixed INFO command to return local server's info if no server
4372 was provided. Affected file lib/silcclient/command.c.
4374 * Removed RESTART command for good. Updated the code and the
4377 * Rewrote parts of the task system. It is a bit simpler now.
4378 Removed unsued task priorities. The affected files are
4379 lib/silcutil/silctask.[ch].
4381 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Moved the USERS printing from the library to the application.
4384 Affected files lib/silcclient/command.c and silc/client_ops.c.
4386 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added channel key re-key support. The re-key is perfomed
4391 only by the router and is done once in an hour. Added `rekey'
4392 field to the SilcChannelEntry in the server. Affected files
4393 silcd/server.c and silcd/idlist.h.
4395 * Added silc_task_unregister_by_context into the file
4396 lib/silcutil/silctask.[ch].
4398 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Added SILC_UMODE_GONE mode to indicate when the client is not
4401 present in the SILC network. Added also support to the local
4402 command AWAY that will set this mode. Added support of showing
4403 "xxx is gone" in WHOIS command. The USERS command shows the
4404 gone status as well.
4406 * Fixed setting server and router operator privileges in the
4407 server's UMODE command. Affected file silcd/command.c.
4409 * Merged the SKE KE1 and KE2 payloads into one payload. The
4410 new KE payload is equivalent to the old KE2 payload.
4412 Cleaned up the SKE Start Payload parsing. It now uses the
4413 simple buffer unformatting to do the parsing. A lot faster
4416 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4417 to the SKE that is used to indicate whether both of the SKE
4418 parties should perform authentication. By default only the
4419 responder performs authentication. By setting this flag also
4420 the initiator must do authentication. By default it is unset
4421 since in normal SKE case, client to server connection, only
4422 the responder should do authentication. When doing SKE between
4423 two clients both should perform authentication. Updated the
4424 code and the protocol specs.
4426 * A little fix to IDENTIFY command in the server. Search the
4427 client first by hash not nickname. Affected file is
4430 * Fixed the silc_client_close_connection to support closing
4431 the client to client connections wihtout deleting too much
4432 data. Affected file lib/silcclient/client.c.
4434 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4435 are received if protocol used to be active but is not anymore
4436 the application would crash due to NULL pointer dereference.
4437 Affected files silcd/server.c and lib/silcclient/client.c.
4439 * Added `hash' field to the SilcClientConnection to include
4440 the hash function negotiated in the SKE protocol.
4442 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4443 to set the channel founder authentication data. A client can
4444 claim the founder rights later by providing the authentication
4445 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4446 This way the channel founder can regain the channel founder
4447 privileges even it is left the channel. This works only on
4448 local server and the client must be connected to the same
4449 server to be able to regain the founder rights. Updated the
4450 protocol specs accordingly.
4452 Added support to the CMODE command in the client to set the
4453 founder auth data. Read the README to see how to set it.
4455 Added support to the CUMODE command to claim the founder
4456 rights. Read the README to see how to do it.
4458 Added support for the founder authentication to the Channel
4459 Entry in the server. Affected file silcd/idlist.h.
4461 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4462 server's CMODE command. Affected file silcd/command.c.
4464 * Added the following new functions into lib/silccore/silcauth.[ch]:
4465 silc_auth_get_method and silc_auth_get_data.
4467 * The server now saves the remote hosts public key to the
4468 SilcIDListData pointer. Affected file silcd/protocol.c.
4470 * The normal server now does not remove the channel entry from
4471 the cache if the founder authentication data is set. It used
4472 to remove it if the founder was the last one on the channel on
4473 the server and left the channel. The auth data is saved and
4474 if the channel is re-joined later the old entry is used with
4475 the old auth data. Affected files silcd/command_reply.c and
4478 * Removed the `pkcs' field from the SilcIDListData structure
4479 in the server; it is not used. Affected file silcd/idlist.h.
4481 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Fixed packet processing on slow links. Partial packets were
4484 never re-processed because the incoming data buffer was cleared
4485 by the application. Application must not directly clear the
4486 sock->inbuf, the packet processing routines handle it. Fixed
4487 this in client library and in server.
4489 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Fixed the WHOIS and IDENTIFY send reply function to really
4492 check whether to send list or just one entry. Affected file
4495 * Cleaned up the LEAVE command's channel key distribution. The
4496 affected file silcd/command.c.
4498 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4499 can enforce the channel mode as well. In that case the ID
4500 includes the ID of the server. The code now enforces the
4501 mode change if the router have different mode than the server.
4503 * The notify client operation with CMODE_CHANGE notify can now
4504 return NULL client_entry pointer if the CMODE was not changed
4505 by client. Application must check for this.
4507 * Added <Server ID> argument to INFO command to support server
4508 info fetching by Server ID.
4510 * Added silc_server_announce_get_channel_users to get assembled
4511 packets of channel users of the specified channel. Affected
4512 file silcd/server.[ch].
4514 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4515 was freed underneath the ID Cache.
4517 * Re-announce clients when the server received CHANNEL_CHANGE
4518 notify from the router. Affected file silcd/packet_send.c.
4520 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4523 crashed since it did not handle the fact that there is no cipher
4524 called "3" and didn't check the error condition. Now fixed.
4526 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4527 flag. It can be used to send message requests.
4529 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Implemented the RESTART command in the client.
4533 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4534 notice type messages. Added notice printing to the user
4537 * The channel keys are not re-generated if the channel's mode
4538 is PRIVKEY, ie private key on the channel exists. Affected
4539 files silcd/server.c and silcd/command.c.
4541 * Fixed a little bug in channel message delivery when channel
4542 private keys are set in the server. Affected file is
4543 silcd/packet_send.c.
4545 * Changed the setting on channel->on_channel = TRUE from the
4546 silc_client_save_channel_key to the JOIN command reply. The
4547 key payload is not received if the private channel key is set.
4548 Affected file lib/silcclient/command_reply.c and the
4549 lib/silcclient/client_channel.c.
4551 * When the CMODE_CHANGE notify is sent and the channel private
4552 key mode is removed the channel key must be re-generated in
4553 other cells as well. Added this support for the router in the
4554 silcd/packet_receive.c.
4556 * Added new local command NOTICE to send notice message on
4557 channel. Affected file silc/local_command.[ch].
4559 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Added new local command ME to the client. It is used to send
4562 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4563 some action. Affected file silc/local_command.[ch].
4565 * Changed channel_message and private_message client operations
4566 to deliver the message flags to the application. Added also
4567 the `flags' arguments to the silc_client_send_channel_message
4568 and silc_client_send_private_message functions. Affected file
4571 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Redefined the Private Message Payload to support private message
4574 keys and to support the new private message flags. Updated
4575 the protocol specs. Flags makes it possible to have for example
4576 CTCP style messages.
4578 * Added new type SilcPrivateMessagePayload and defined an API
4579 for it in the lib/silcclient/silcprivate.[ch].
4581 * Tested private message private keys successfully. Tested the
4582 private message key set, unset and list commands with the new
4585 * Redefined the Channel Message Payload to include the channel
4586 message flags (equal with private message flags) to support
4587 for example CTCP style messages.
4589 * Defined some of the message (for channel and private message)
4590 flags. Updated the protocol specs and added the flags to the
4591 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4593 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Added SilcKeyAgreementStatus type to the key agreement routines
4596 to indicate the current status and error if one occured.
4597 The status types are defined in the lib/silcclient/silcapi.h.
4599 * Added new local command KEY that is used to set and unset private
4600 keys for channels, set and unset private keys for private messages
4601 with remote clients and to send key agreement requests and
4602 negotiate the key agreement protocol with remote client. The
4603 key agreement is supported only to negotiate private message keys,
4604 it currently cannot be used to negotiate private keys for channels,
4605 as it is not convenient for that purpose.
4607 * Fixed a minor pending callback setting bug in the function
4608 silc_client_get_client_by_id_resolve, now the function works.
4609 Affected file lib/silcclient/idlist.c.
4611 * Added function silc_net_get_local_port to get local bound
4612 port by socket. Added to lib/silcutil/silcnet.[ch].
4614 * Added `sockets' and `sockets_count' fields to the SilcClient
4615 object. They hold the sockets of the listenning sockets in
4616 the client. Listenning sockets may be for example the key
4617 agreement server. Affected file lib/silcclient/client.[ch].
4618 Added functions the silc_client_add_socket and the
4619 silc_client_del_socket. They are exported to the application
4622 * Added ~./silc/clientkeys to support other client's public keys.
4624 * Renamed verify_server_key client operation to verify_public_key
4625 and added one argument to indicate the type of the connection
4626 (server, client etc.).
4628 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Added silc_server_connection_auth_request to handle the
4631 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4632 silcd/packet_receive.[ch].
4634 * Added silc_server_send_connection_auth_request into the
4635 silcd/packet_send.c to send the connection auth request packet.
4637 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4640 * Fixed the public key authentication in responder side in the
4641 server. The `auth_data' pointer includes the SilcPublicKey
4642 not the path to the public key. Affected file silcd/protocol.c.
4644 * Implemented the public key authentication in the initiator side
4645 in the server. Affected file silcd/protocol.c.
4647 * Removed the [RedirectClient] config section from the server
4648 configuration. Is not needed and I don't want to implement it.
4650 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Cleaned up the CMODE command in the server. It now works
4653 correctly and supports all the modes defined in the protocol.
4654 Affected file is silcd/command.c.
4656 * Added `hmac_name' field to the SilcChannelEntry in the server
4657 to hold the default HMAC of the channel. It can be set when
4658 creating the channel (with JOIN command). Affected files
4661 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4662 type to indicate the change of the current cipher and hmac
4663 on the channel. Client can safely ignore the <cipher> argument
4664 (if it chooses to do so) since the CHANNEL_KEY packet will
4665 force the channel key change anyway. The <hmac> argument is
4666 important since the client is responsible of setting the new
4667 HMAC and the hmac key into use.
4669 * Fixed the CMODE command in the client library as well.
4671 * Tested CMODE command in router environment successfully.
4673 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Show the version of the remote client (or server) when connecting
4676 to the server. It is logged to the log file. Affected file
4677 is silcd/protocol.c.
4679 * Fixed the KILLED notify handling in the client library. The
4680 client must be removed from all channels when receiving the
4683 Also, do not remove the client entry when giving the KILL
4684 command but when the KILLED notify is received.
4686 * Removed silc_idlist_find_client_by_nickname from the server.
4687 Not needed anymore. Affected files silcd/idlist.[ch].
4689 * Implemented the CHANNEL_CHANGE notify type handling to the
4690 server. Affected file silcd/server.c.
4694 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Added silc_server_send_notify_invite to send the INVITE
4697 notify between routers.
4699 * Implemented the INVITE command correctly to the server.
4701 * Implemented the INVITE notify type handling in the server.
4703 * Implemented the INVITE command to the client library and on the
4706 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Added function silc_server_get_client_resolve to find the
4709 client entry by ID from all ID lists and then resolve it
4710 (using WHOIS) if it cannot be found. Affected file is
4713 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Implemented the BAN command to the client library.
4717 * The JOIN command in the server now checks the invite list
4720 * Changed the silc_command_reply_payload_encode_va and the
4721 silc_command_payload_encode_va to support that if argument is
4722 NULL it ignores and checks the next argument. Affected file
4723 lib/silccore/silccommand.c.
4725 * Added silc_server_send_notify_ban to send the BAN notify
4726 type between routers.
4728 * Chaned the silc_notify_payload_encode to support that if
4729 argument is NULL it ignores and checks the next argument.
4730 Affected file lib/silccore/silcnotify.c.
4732 * Tested ban lists in router environment successfully.
4734 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Implemented BAN command to the server, in silcd/command.[ch].
4738 * Removed the BAN and INVITE_LIST modes from the CMODE command
4741 * Added function silc_string_match to regex match two strings.
4742 Affected files lib/silcutil/silcutil.[ch].
4744 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Redefined parts of the SilcChannelEntry in the server to support
4747 the new ban and invite lists.
4749 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Redefined the INVITE command. The same command can be used to
4752 invite individuals to the channel but also to manage the invite
4753 list of the channel (to add to and remove from the invite list).
4754 Updated the protocol specs.
4756 * Added new command SILC_COMMAND_BAN that can be used to manage
4757 the ban list of the channel. Updated the protocol specs.
4759 * Removed the channel modes: the SILC_CMODE_BAN and the
4760 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4761 in the CMODE command. The equivalent features are now available
4762 using INVITE and BAN commands. Updated the protocol specs.
4764 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4765 in the network about change in the current ban list. The notify
4766 type is not used by the client.
4768 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4769 support the invite lists.
4771 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Added new function silc_string_regexify that converts string
4774 including wildcard characters into regex string that can
4775 be used by the GNU regex library. Added into the file
4776 lib/silcutil/silcutil.[ch].
4778 Added silc_string_regex_combine to combine to regex strings
4779 into one so that they can be used as one regex string by
4780 the GNU regex library. Added into the file
4781 lib/silcutil/silcutil.[ch].
4783 Added silc_string_regex_match to match two strings. It returns
4784 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4786 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Imported GNU regex to the soruce tree into lib/contrib.
4789 Fixed some compiler warning from the regex.c.
4791 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Fixed MOTD command in the server to work in router environment.
4795 * Fixed the MOTD command in the client library to support
4796 the server argument in the command.
4798 * Added `nickname_len' argument to the silc_idlist_add_client
4799 in the server, as the `nickname' argument may be binary data
4802 * Added silc_idlist_get_channels to return all channels from
4805 * Implemented LIST command to the server. Affected file is
4808 * Implemented the LIST command to the client library and on the
4811 * Added [<user count>] argument to the LIST command reply.
4812 With private channels the user count is not shown.
4814 * Updated TODO and README.
4816 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4818 * The client entry's data.registered must be TRUE even with
4819 global client entry on global client list. The data.registered
4820 is used to check whether the client is anymore in the network,
4821 for example with WHOWAS command so it must be valid.
4823 * Fixed the WHOWAS command in the server. It now actually works
4824 in router environment. Added function into silcd/command_reply.c
4825 silc_server_command_reply_whowas_save.
4827 * Added silc_idlist_purge function to the silcd/idlist.c
4828 to periodically purge the ID Cache.
4830 * Fixed INFO command in the server. It works now in router
4831 environment. Added <server name> argument to the INFO command
4832 reply. Updated the protocol specs.
4834 * Fixed minor bug in silc_idcache_purge to not purge if the
4835 expire value is zero.
4837 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4838 they were buggy because of the WHOWAS information.
4840 * Fixed local command MSG to handle the async resolving of
4841 the remote client properly. It used to fail the first MSG.
4842 Affected file silc/local_command.c.
4844 * Added `data_len' field to SilcIDCache context.
4846 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Update TODO. Todo in commands in the server.
4850 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4853 used by routers as broadcast packet to inform other routers
4854 about the changed user mode.
4856 Implemented the notify handling in the server. Affected file is
4857 silcd/packet_receive.c. Added the function
4858 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4860 * Added new generic Channel Payload and deprecated the New Channel
4861 Payload. The New Channel Payload is now the generic Channel
4864 * Added new argument `mode' to the silc_server_send_new_channel
4865 as it is required in the Channel Payload now.
4867 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4868 and created a new and real SilChannelPayload to represent the
4869 new generic Channel Payload. Implemented the encode/decode
4870 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4872 * Added silc_server_get_client_channel_list to return the list
4873 of channels the client has joined for WHOIS command reply.
4874 Affected file silcd/server.[ch].
4876 * Implemented the channel list sending in the WHOIS command reply
4877 in server and in the client.
4879 Implemented the channel list displaying on the user interface
4880 as well. Affected file silc/client_ops.c.
4882 * Added silc_channel_payload_parse_list to parse list of Channel
4883 Payloads. It returns SilcDList list of SilcChannelPayloads.
4884 Client for example can use this function to parse the list of
4885 channels it receives in the WHOIS command reply. The caller
4886 must free the list by calling silc_channel_payload_list_free.
4887 Affected files lib/silccore/silcchannel.[ch].
4889 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Added one new argument <user mode> to the WHOIS command reply
4892 to return the mode of the user in SILC. Updated the protocol
4895 Implemented it to the server and client.
4897 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Fixed the mode printing on the user interface on joining.
4900 Affected file silc/client_ops.c.
4902 * Implemented the UMODE command and user modes in general to the
4903 client library and to the user interface.
4905 * Implemented the UMODE command to the server.
4907 * The server now sends UNKNOWN_COMMAND error status if client sends
4908 unknown command. Affected file silcd/command.c.
4910 * All server commands now handle the command identifier the right
4911 way when sending the command reply to the client. The client can
4912 use to identify the command replies with the identifier.
4914 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Added silc_server_get_client_route to resolve the route to
4917 the client indicated by the client ID. Affected file is
4920 * Added silc_server_relay_packet as general function to relay
4921 packet to arbitrary destination. This deprecates functions
4922 like _send_private_message_key, _relay_notify etc. Affected
4923 file is silcd/packet_send.[ch].
4925 Removed silc_server_send_key_agreement,
4926 silc_server_send_private_message_key and
4927 silc_server_packet_relay_notify functions from the file
4928 silcd/packet_send.[ch].
4932 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4933 server. Affected file silcd/packet_receive.[ch].
4935 * Implemented the KILL command to the client. Implemented the
4936 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4937 Affected files lib/silcclient/command[_reply].c and
4938 lib/silcclient/client_notify.c. Implemented the KILL notify
4939 printing in the user inteface.
4941 * Fixed a lot silc_parse_nick memory leaks from the client
4942 library in the file lib/silcclient/command.c.
4944 * Changed the silc_server_send_notify_on_channels's `sender'
4945 argument from SilcSocketConnection to SilcClientEntry to
4946 check the sender as entry and not as connection object and not
4947 to send to the client provided as argument. The affected file
4948 is silcd/packet_send.[ch].
4950 * The notify packets that are destined directly to the client used
4951 to not to be processed by the server. Now changed that and the
4952 server processes all notify packets. After relaying the packet
4953 to the client the notify packet is processed in the server.
4955 * The silc_server_free_client_data now checks whether there is
4956 pending outgoing traffic for the client and purges the data to
4957 the network before removing the client entry.
4959 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4962 an client is killed from the SILC Network. Updated the protocol
4965 Added new function silc_server_send_notify_killed to the
4966 silcd/packet_send.[ch].
4968 * Added function silc_server_packet_relay_notify to relay notify
4969 packets that are destined directly to a client. In this case
4970 the server does not process the notify packets but merely relays
4971 it to the client. Affected file silcd/packet_send.[ch].
4973 Added also silc_server_packet_process_relay_notify to check
4974 whereto relay the notify. Affected file is
4975 silcd/packet_receive.[ch].
4977 * Implemented the KILL command to the server.
4981 * Added the backup schema desgined last fall to the protocol
4982 specs for everyone to see. The specification is in the
4983 *-spec-xx.txt draft and the packet type definitions for the
4984 backup routers is in *-pp-xx.txt draft. Thusly, added also
4985 new packet type SILC_PACKET_CELL_ROUTERS.
4987 * A big security problem in the implementation discovered. The
4988 signoff of an client did not cause new channel key generation
4989 which it of course should've done. The channel keys must be
4990 always re-generated when client leaves (or signoffs) the channel.
4991 The silc_server_remove_from_channels funtion now handles
4992 the channel key re-generation.
4994 * Added `sender' argument to the silc_server_send_notify_on_channels
4995 to not to send the client provided as argument. Affected file
4996 silcd/packet_send.[ch].
4998 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Implemented OPER and SILCOPER commands into the server and
5003 * Added silc_auth_verify and silc_auth_verify_data to verify
5004 the authentication directly from the authentication payload.
5005 It supports verifying both passphrase and public key based
5006 authentication. Affected file lib/silccore/silcauth.[ch].
5008 * Added `hash' field to the SilcIDListData structure. It is the
5009 hash negotiated in the SKE protocol. Affected file is
5012 * Slight redesigning of the SilcAuthPayload handling routines.
5013 Do not send SilcPKCS but SilcPublicKey as argument.
5015 * Implemented the public key authentication support to the
5016 serverconfig. The public key is loaded from the provided path
5017 and saved as authentication data to void * pointer. Thus,
5018 changed the unsigned char *auth_data to void *auth_data;
5020 * Fixed SHUTDOWN command to send the reply before the server
5021 is shutdown. :) Affected file silcd/command.c.
5023 * Fixed fatal bug in CONNECT command. The hostname was invalid
5024 memory and server crashed. Affected file silcd/command.c.
5026 * Fixed fatal bug in CLOSE command. The server_entry became
5027 invalid but was referenced later in the command. Affected file
5030 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Fixed fatal bug in failure packet handling. Server ignored
5033 the failure and thus crashed when it came.
5037 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5040 that the command may be executed only once in (about) 2 seconds.
5041 The old SILC_CF_LAG flag is same but allows command bursts up
5042 to five before limiting.
5044 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5045 server code. Various commands now includes the CF_LAG_STRICT
5046 flag to disallow any kind of miss-use of the command.
5048 * Fixed the silc_buffer_unformat to not to allocate any data
5049 if the length of the data is zero. It used to allocate the
5050 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5052 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Changed the format of AdminConnection configuration section
5055 in the server. Added username of the admin to the format.
5056 Affected files silcd/serverconfig.[ch].
5058 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5059 to return admin configuration data by host, username and/or
5062 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Implemented WHOWAS command to the server. Added the functions:
5066 silc_server_command_whowas_parse,
5067 silc_server_command_whowas_send_reply,
5068 silc_server_command_whowas_from_client and
5069 silc_server_command_whowas_from_server
5071 * Added <Client ID> argument to the WHOWAS command reply. Updated
5072 the protocol specs accordingly.
5074 * Implemented WHOWAS command and command_reply to the client
5077 Implemented the WHOWAS printing on the user interface.
5079 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Added new argument to the WHOWAS command reply, the real name.
5082 It is an optional argument. Updated the protocol specs.
5084 * Added SilcIDCacheDestructor callback that is registered when
5085 the SilcIDCache is allocated. The callback is called when
5086 an cache entry in the ID Cache expires, or is purged from the
5087 cache. Added into lib/silccore/idcache.[ch].
5089 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5090 to destruct the client entries when the cache entry expires.
5091 Other ID Cache's in server and in the client library ignores
5094 * If the ID Cache entry's `expire' field is zero then the entry
5095 never expires. Added boolean `expire' argument to the
5096 silc_idcache_add function in the lib/silccore/idcache.[ch].
5097 If it is TRUE the default expiry value is used.
5099 * Added silc_server_free_client_data_timeout that is registered
5100 when client disconnects. By default for 5 minutes we preserve
5101 the client entry for history - for WHOWAS command.
5103 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Added support to the server to enforce that commands are not
5106 executed more than once in 2 seconds. If server receives
5107 commands from client more frequently, timeout is registered
5108 to process the commands. Affected file silcd/command.c.
5109 Added new function silc_server_command_process_timeout.
5111 * Changed NICK_NOTIFY handling in client library to check that
5112 if the client's nickname was changed, so there is no need to
5113 resolve anything from the server.
5115 * Removed error printing from the WHOIS and IDENTIFY commands.
5116 If error occurs then it is ignored silently in the client library.
5117 The application, however, may map the received error to
5118 human readable error string. The application currently maps
5119 the NO_SUCH_NICKNAME error to string.
5121 * Made the command status message public to the application. Moved
5122 them from lib/silcclient/command_reply.c to
5123 lib/silcclient/command_reply.h. The application can map the
5124 received command status to the string with the
5125 silc_client_command_status_message function.
5127 * Added check to the server to check that client's ID is same
5128 as the Source ID in the packet the client sent. They must
5131 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Added dist-bzip hook to the Makefile.am to make bzip2
5134 compressed distributions.
5136 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Server now enforces the maximum length for the nickname and
5139 the channel as protocol specification dictates. 128 bytes for
5140 nickname and 256 bytes for channel name.
5142 * Moved the WHOIS printing to the application. The client libary
5143 does not print out the WHOIS information anymore, the application
5144 must do it. Renamed silc_client_command_reply_whois_print to
5145 the silc_client_command_reply_whois_save.
5147 The client's idle time is also sent to the application now, and
5148 the idle is shown on screen.
5150 * Added silc_client_command_reply_identify_save to save the
5151 received IDENTIFY entries.
5153 * Do not check for channel private keys in message sending and
5154 reception if the channel does not have the PRIVKEY mode set.
5155 Affected file lib/silclient/client_channel.c.
5157 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5160 just surfaced after chaning the JOIN procedure.
5162 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Added silc_client_get_clients_by_list to get client entries
5165 from Client ID list, that is returned for example by JOIN
5166 and USERS command replies. The application should use this
5167 function for example when JOIN command reply is received to
5168 resolve the clients already on the channel (library does not
5169 do that anymore as USERS command reply is not used in the JOIN
5170 procedure anymore). Affected files lib/silcclient/silcapi.h and
5171 lib/silcclient/idlist.c.
5173 * JOIN command reply and USERS command reply returns now SilcBuffer
5174 pointers instead of unsigned char pointers when returning
5175 the client list and mode list.
5177 * Added <Client ID> argument to the JOIN command reply, mainly
5178 for the server to identify for which client the command was
5179 originally sent. Updated protocol specs accordingly.
5181 * Added SilcDlist private_key pointer to the SilcChannelEntry
5182 in the client to support the channel private keys. Affected
5183 file is lib/silcclient/idlist.h.
5185 * Added SilcChannelPrivateKey argument to the function
5186 silc_client_send_channel_message so that application can choose
5187 to use specific private ke if it wants to. If it is not provided,
5188 the normal channel key is used, unless private keys are set.
5189 In this case the first (key that was added first) is used
5190 as the encryption key.
5192 * Implemented the support for channel private key handling.
5193 Implemented the following functions:
5195 silc_client_add_channel_private_key,
5196 silc_client_del_channel_private_keys,
5197 silc_client_del_channel_private_key,
5198 silc_client_list_channel_private_keys and
5199 silc_client_free_channel_private_keys
5201 Affected file lib/silcclient/client_channel.c.
5203 * Added the support for the private keys in the channel message
5204 sending and encryption and in the message reception and
5205 decryption. Affected funtions are
5206 silc_client_send_channel_message and silc_client_channel_message.
5208 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Added SKE's key verify callback to the client library's
5211 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5213 * Removed the statement that server (or router) must send USERS
5214 command reply when joining to the channel so that the client
5215 knows who are on the channel. Instead, the client list and
5216 client's mode list is now sent in the JOIN command reply to the
5217 client who joined channel. This is better solution.
5219 * Added function silc_server_get_users_on_channel and function
5220 silc_server_save_users_on_channel to the silcd/server.[ch].
5222 * Removed function silc_server_command_send_users from the
5225 * Do not show topic on the client library anymore. The topic is
5226 sent in the command reply notify to the application and the
5227 application must show the topic now.
5229 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Added client searching by nickname hash into the IDENTIFY and
5232 WHOIS commands in the server as they were clearly missing from
5233 them. Affected file is silcd/command.c.
5235 * Fixed a bug in private message receiving in the client library.
5236 The remote ID was freed and it wasn't supposed, now it is
5239 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Minor fix to the channel payload; allocate the data area, as it
5242 needs to be of specific length.
5244 * If the key agreement port is zero then the operating
5245 system will define the bound port. Affected files are
5246 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5248 * Added new function silc_channel_payload_decrypt into the file
5249 lib/silccore/silcchannel.[ch].
5251 * Moved the channel message etc, check from silc_packet_decrypt
5252 to applications. The library calls now a generic
5253 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5254 when the packet is either normal or special. This was done to
5255 allow more wide range of checking that was not allowed when
5256 the code was in library. Now applications can do virtually any
5257 checks to the packet and return to the library the decision how
5258 the packet should be processed. Affected files are
5259 lib/silccore/silcpacket.[ch].
5261 Added silc_server_packet_decrypt_check to the server and
5262 silc_client_packet_decrypt_check to the client library.
5264 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5265 to send with specified source and destination information.
5267 * Channel message delivery between routers was broken after the
5268 channel key distribution was fixed earlier. The channel key
5269 was used be to distributed to other routers as well which is not
5270 allowed by the protocol. Now this is fixed and channel keys
5271 really are cell specific and the channel message delivery between
5272 routers comply with the protocol specification.
5274 * Fixed various commands in server to check also the global list
5275 for the channel entry and not just the local list. The affected
5276 file silcd/command.c.
5278 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added assert()s to buffer formatting and unformatting routines
5281 to assert (if --enable-debug) when error occurs. Affected
5282 file: lib/silcutil/silcbuffmt.c.
5284 * Changed to auto-reconnect to check whether the remote host is
5285 router and register the re-connect timeout if it is. It used
5286 to check that whether we are normal server, but router must do
5287 auto-reconnect with another router as well. Affected file
5290 * Removed the [<key len>] option from CMODE command as the cipher
5291 name decides the key length, nowadays. See the defined ciphers
5292 from the protocol specification.
5294 * Added [<hmac>] option to the CMODE command to define the HMAC
5295 for the channel. Added SILC_CMODE_HMAC channel mode.
5297 * Added [<hmac>] option for the JOIN command so that user can
5298 select which HMAC is used to compute the MACs of the channel
5301 * Added Hmac field to the Channel Message Payload. The integrity
5302 of plaintext channel messages are now protected by computing
5303 MAC of the message and attaching the MAC to the payload. The
5304 MAC is encrypted. Now, it is clear that this causes some
5305 overhead to the size of the packet but rationale for this is that
5306 now the receiver can verify whether the channel message decrypted
5307 correctly and also when private keys are set for the channel the
5308 receiver can decrypt the packet with several keys and check from
5309 the MAC which key decrypted the message correctly.
5311 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5312 lib/silccrypt/silccipher.[ch].
5314 * Added silc_hash_len to return the digest length into the
5315 lib/silcrypt/silchash.[ch].
5317 * Rewrote parts of Silc Channel Payload interface in the
5318 lib/silccore/silcchannel.[ch]. The encode function now also
5319 encrypts the packet and parse function decrypts it.
5321 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Fixed a minor formatting bug in the SKE's key material processing.
5324 It actually might have processed the keys wrong way resulting
5327 * Redefined the mandatory HMAC algorithms and added new algorithms.
5328 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5329 and hmac-md5 truncated to 96 bits. The mandatory is now
5330 hmac-sha1-96. Rest are optional (including the one that used
5331 to be mandatory). Rationale for this is that the truncated HMAC
5332 length is sufficient from security point of view and can actually
5333 make the attack against the HMAC harder. Also, the truncated
5334 HMAC causes less overhead to the packets. See the RFC2104 for
5337 * Added new [hmac] configuration section. The SKE used to use
5338 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5339 is of course wrong. The official names that must be proposed in
5340 the SKE are the ones defined in the protocol specification
5341 (hmac-sha1-96 for example). The user can configure any hmac
5342 using any hash function configured in the [hash] section. At
5343 least, the mandatory must be configured.
5345 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5347 * Added HMAC list to the SKE proposal list. It has now both
5348 hash algorithm list and HMAC list. This makes the protocol
5349 incompatible with previous versions. The SKE now seems to work
5350 the way it is supposed to work, for the first time actually.
5352 * Defined plain Hash algorithms to the protocol specification.
5355 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Implemented support for key agreement packets into the server.
5358 Added functions silc_server_key_agreement and
5359 silc_server_send_key_agreement. Other than these functions,
5360 server has nothing to do with this packet.
5362 * Added support for private message key packets into the server.
5363 Added functions silc_server_private_message_key and
5364 silc_server_send_private_message_key.
5368 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5369 called in the protocol's final callback instead in the END
5370 protocol state. This makes a little more sense and in the same
5371 time in client we can use the same protocol routines for normal
5372 key exchange and to key agreement packet handling as well.
5374 * Added to both client's and server's KE protocol context the
5375 SilcSKEKeyMaterial pointer to save the key material. We will
5376 bring the key material to the protocol's final callback by doing
5377 this. The final callback must free the key material.
5379 * Added SKE's packet_send callback into client's KE protocol
5380 context so that the caller can choose what packet sending function
5381 is used. This way we can use different packet sending when
5382 doing normal SKE when doing key agreement packet handling (in
5383 the key agreement packet handling we do not want to encrypt
5386 * Implemented the responder side of the key agreement routines
5387 in the client. The client can now bind to specified port and
5388 accept incoming key negotiation. The key material is passed
5389 to the application after the protocol is over.
5391 * Implemented the processing of incoming Key Agreement packet
5392 in the client. Added function silc_client_key_agreement to
5395 * Implemented the intiator side of the key agreement routines
5396 in the client. The client can now initiate key agreement with
5397 another remote client. The key material is passed to the
5398 application after the protocol is over.
5400 * Created client_keyagr.c to include all the key agreement
5403 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5404 SILC_TASK_CALLBACK except that it is not static.
5406 * Created client_notify.c and moved the Notify packet handling
5407 from the client.[ch] into that file.
5409 * Created client_prvmsg.c and moved all private message and
5410 private message key routines from the client.[ch] into that file.
5412 * Create client_channel.c and moved all channel message and
5413 channel private key routines from the client.[ch] into that file.
5415 * Changed silc_client_get_client_by_id_resolve to resolve with
5416 WHOIS command instead of IDENTIFY command, in the file
5417 lib/silclient/idlist.c.
5419 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Implemented the SKE's responder side to the Client library.
5423 * When FAILURE is received to the protocol do not trust it
5424 blindly. Register a timeout to wait whether the remote closes
5425 the connection as it should do it, only after that process the
5426 actual failure. This was changed to both client and server.
5428 * Added client_internal.h to include some of the structures
5429 there instead of client.h in lib/silcclient/.
5431 * Added function silc_task_unregister_by_callback to unregister
5432 timeouts by the callback function.
5434 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Some "Incomplete WHOIS info" errors has been appearing on the
5437 log files. Took away the entry->userinfo check from WHOIS
5438 reply sending. The entry->userinfo is now " " if client did not
5439 provide one. I thought this was fixed earlier but something
5440 is wrong still. Let's see if the error still appears.
5442 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Fixed a minor bug in the login when the channel key is
5445 re-generated in the server. It used to generate the key in
5446 wrong order and thus caused problems in the channel traffic.
5448 * Fixed a minor bug in channel key distsribution after
5449 KICK command. The key was not sent to the router even though
5452 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added silc_ske_process_key_material_data as generic routine
5455 to process any key material as the SILC protocol dictates. The
5456 function is used by the actual SKE library but can be used by
5457 applications as well. This relates to the private message keys
5458 and the channel private keys since they must be processed the
5459 same way the normal SILC session keys. The protocol dictates
5460 this. Affected files: lib/silcske/silcske.[ch].
5462 Added also silc_ske_free_key_material to free the
5463 SilcSKEKeyMaterial structure.
5465 * Defined silc_cipher_set_key function to set the key for
5466 cipher without using the object's method function. The affected
5467 files: lib/silccrypt/silccipher.[ch].
5469 * Implemented silc silc_client_add_private_message_key,
5470 silc_client_add_private_message_key_ske,
5471 silc_client_del_private_message_key,
5472 silc_client_list_private_message_keys and
5473 silc_client_free_private_message_keys functions in the
5476 Added functions silc_client_send_private_message_key to send
5477 the Private Message Key payload and silc_client_private_message_key
5478 to handle incoming Private Message Key payload.
5480 * Added Cipher field to the Private Message Key payload to set
5481 the cipher to be used. If ignored, the default cipher defined
5482 in the SILC protocol (aes-256-cbc) is used.
5484 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Removed lib/silcclient/ops.h file.
5488 Redefined parts of the SILC Client Library API. Created new
5489 file silcapi.h that deprecates the ops.h file and defines the
5490 published Client Library API. Defined also private message key
5491 API and channel private key API into the file.
5493 This is the file that the application must include from the
5494 SILC Client Library. Other files need not be included by
5495 the application anymore.
5497 * Added new key_agreement client operation callback and also
5498 defined the Key Agreement library API for the application.
5500 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5503 is used by clients to request key negotiation between another
5504 client in the SILC network. If the negotiation is started it
5505 is performed using the SKE protocol. The result of the
5506 negotiation, the secret key material, can be used for example
5507 as private message key.
5509 Implemented the Key Agreement payload into the files
5510 lib/silccore/silauth.[ch].
5512 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Redefined ciphers for the SILC protocol. Added some new ciphers
5515 and defined the key lengths for the algorithms. Changed the
5516 code accordingly. The default key length is now 256 bits.
5518 * Fixed SKE key distribution function silc_ske_process_key_material
5519 when the key length is more than 128 bits. The default key
5520 length in SILC is now 256 bits.
5522 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5523 to indicate unsupported algorithm.
5525 * Renamed rijndael.c to aes.c and all functions as well.
5527 * Fixed a long standing channel key setting bug in client library.
5528 Weird that it has never surfaced before.
5530 * Fixed bug in channel deletion. If the entire channel is removed
5531 then it must also delete the references of the channel entry
5532 from the client's channel list as the client's channel entry and
5533 the channel's client entry share same memory.
5535 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Implemented CONNECT and SHUTDOWN commands in the client.
5539 * Implemented CLOSE command to the client.
5541 * Added the function silc_idlist_find_server_by_name into the
5542 files silcd/idlist.[ch].
5544 Added the function silc_idlist_find_server_by_conn into the
5545 files silcd/idlist.[ch].
5547 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * DIE command was renamed to SHUTDOWN. Updated the both code
5552 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5553 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5555 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5558 * Added function silc_server_create_connection function to create
5559 connection to remote router. My server implementation actually
5560 does not allow router to connect to normal server (it expects
5561 that normal server always initiates the connection to the router)
5562 so the CONNECT command is only good for connecting to another
5565 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5568 or some other client was kicked from the channel.
5570 Implemented the handling of the notify type to both client
5573 Implemented silc_server_send_notify_kicked to send the KICKED
5574 notify. It is used to send it to the server's primary router.
5576 * Implemented the KICK command into server and client.
5578 * Added `query' argument to the silc_idlist_get_client function
5579 to indicate whether to query the client from server or not if
5582 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5583 to indicate that the client is not channel founder.
5587 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Removed the rng context from SilcPacketContext structure and
5590 changed that the packet routine uses the Global RNG API.
5592 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Added support for quit message that client can "leave" on the
5595 channel when it quits the SILC. It is ditributed inside the
5596 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5598 Added silc_server_free_client_data that will take the
5599 signoff message as argument.
5601 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5603 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Updated parts of the protocol specification to keep it up
5608 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5611 payloads in one packet.
5613 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5614 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5615 use now the new List flag.
5617 * Also deprecated the following packet types: REPLACE_ID,
5618 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5620 * Added list support for Notify packet in server.
5622 * Added silc_server_send_notify_channel_change to send the
5623 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5624 the silc_server_send_replace_id.
5626 * Added silc_server_send_notify_nick_change to send the
5627 NICK_CHANGE notify type. Deprecates the function
5628 silc_server_send_replace_id.
5630 * Added silc_server_send_notify_join to send the JOIN notify type.
5631 Deprecates the function silc_server_send_new_channel_user.
5633 * Added silc_server_send_notify_leave to send LEAVE notify type.
5634 Deprecates the function silc_server_send_remove_channel_user.
5636 * Added silc_server_send_notify_cmode and
5637 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5638 types. Deprecates the silc_server_send_set_mode function.
5640 * Added SERVER_SIGNOFF notify type to indicate that server has
5641 quit. This means that all clients on the channel from that
5642 server will drop. This can be also used when netsplit happens.
5644 Deprecated REMOVE_ID packet type since it is not needed anymore
5647 Added silc_server_send_notify_server_signoff to send the
5648 SERVER_SIGNOFF notify type. Deprecates the function
5649 silc_server_send_remove_id.
5651 Added also silc_server_send_notify_signoff to send the
5652 SIGNOFF notify type.
5654 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5655 SILC protocol from this day on. Changed the protocol
5656 specification as well.
5658 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5659 notify type. It is used between routers to notify about
5660 topic changes on a channel.
5662 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5665 * Partly updated the protocol specification to comply with the
5666 changes now made. It is still though a bit outdated.
5668 * The JOIN notify type now takes one extra argument <Channel ID>.
5669 The packet used to be destined to the channel but now the
5670 JOIN type may be sent as list thus it is impossible to
5671 destine it to any specific channel. By adding this argument
5672 it is again possible.
5674 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added CREDITS file. The CHANGES and CREDITS file will appear
5677 in the distribution as well.
5679 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5682 types in the server's silcd/packet_receive.c.
5684 * Implemented CMODE and CUMODE to work in router environment.
5686 * Fixed minor encoding and decoding buglet from the
5687 lib/silccore/silcmode.c.
5689 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5692 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5694 * Changed all SilcConfigServer* and silc_config_server* to
5695 SilcServerConfig* and silc_server_config*, respectively.
5698 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Associated the ID (client or server ID) to the Authentication
5701 Payload to avoid any possibility of forging. Updated the
5702 protocol specification and the code accordingly.
5704 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * The RSA key length is now save to the RsaKey context in the
5707 key generation process in lib/silccrypt/rsa.c. The key length
5708 is now used to figure out the maximum size of the block allowed
5709 to be encrypted/signed.
5711 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5712 is equivalent to the silc_mp_mp2bin but does not allocate any
5715 * Changed silc_mp_mp2bin API to take length argument. If it is
5716 non-zero then the buffer is allocated that large. If zero, then
5717 the size is approximated using silc_mp_sizeinbase, which however
5720 * Created Global RNG API which is global RNG that application can
5721 initialize. After initializing, any routine anywhere in the
5722 code (including library) can use RNG without allocating a new
5723 RNG object. This was done to allow this sort of use of the
5724 RNG in code that has no chance to allocate RNG object. All
5725 applications currently allocate this and many routines in the
5726 library use this. Affected file lib/silccrypt/silcrng.[ch].
5728 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5729 it to use the Global RNG API.
5731 * Defined Authentication Payload into protocol specification that
5732 is used during SILC session to authenticate entities. It is
5733 used for example by client to authenticate itself to the server
5734 to obtain server operator privileges.
5736 Implemented this payload into the lib/silccore/silcauth.[ch].
5737 Implemented also routines for public key based authentication
5738 as the new protocol specification dictates.
5740 Moved definitions of different authentication methods from
5741 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5743 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5744 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5745 silc_pkcs_verify_with_hash functions into the file
5746 lib/silccrypt/silcpkcs.[ch].
5748 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * The client entry's userinfo pointer must be always valid.
5751 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5752 will fail since it requires the userinfo. Now, the userinfo
5753 is allocated as "" if actual userinfo does not exist. Actually,
5754 it must exist and it is totally Ok to drop client connections
5755 that does not announce the userinfo. However, we will make
5756 this workaround for now.
5758 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5759 to return the remote port by socket.
5761 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5764 SILC_SERVER_PENDING_EXEC and added an new macro
5765 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5766 data or when error occurs while processing the pending command.
5768 Added new argument `destructor' into silc_server_command_pending
5769 and to the SilcServerCommandPending object. This destructor is
5770 now called after calling the pending callback or if error occurs
5771 immediately. If error occurs the actual pending callback won't
5772 be called at all - only the destructor. The destructor may be
5773 NULL if destructor is not needed.
5775 All this applies for client library code as well. Similar
5776 changes were made there as well for the pending commands.
5778 In the client, the application must now allocate the
5779 SilcClientCommandContext with the silc_client_command_alloc
5782 * Added reference counter to the SilcServerCommandContext. Added
5783 function silc_server_command_alloc and silc_server_command_dup
5786 Same type of functions added to the client library for the same
5789 * Removed the cmd_ident from IDListData away since it is now
5790 global for all connections. It is the command identifier used
5791 in command sending and with pending commands. The affected file
5794 * Added reference counter to the SilcSocketConnection objecet to
5795 indicate the usage count of the object. The object won't be
5796 freed untill the reference counter hits zero. Currently only
5797 server uses this, and client ignores it. The client must be
5798 set to use this too later. The affected files are
5799 lib/silccore/silcsockconn.[ch]. Added also the function
5800 silc_socket_dup to increase the reference counter.
5802 This was mainly added because it is possible that the socket
5803 is removed underneath of pending command or other async
5804 operation. Now it won't be free'd and proper DISCONNECTING
5805 flags, etc. can be set to avoid sending data to connection that
5806 is not valid anymore.
5808 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5809 the connection. After that it sets SILC_SET_DISCONNECTED.
5810 It is, however, possible that the socket data is not still freed.
5811 The silc_server_packet_process now checks that data is not
5812 read or written to connection that is DISCONNECTED. The socket
5813 get's freed when the reference counter hits zero.
5815 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Changed the client operation API: channel_message operation's
5818 `sender' is now the client entry of the sender, not the nickname
5819 and the `channel' is the channel entry, not the channel name.
5821 In the private_message operation the `sender' is now also the
5822 client entry of the sender not the nickname.
5824 Affected file is lib/silcclient/ops.h and all applications
5825 using the client operations.
5827 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Moved the calling of ops->connect() from connect_to_server_final
5830 into receive_new_id functin since that is the point when the
5831 client is actually allowed to send traffic to network. The
5832 affected file is lib/silcclient/client.c.
5834 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5837 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5838 (if needs broadcasting) instead of broadcasting the packets one
5839 by one which would make a burst in the network traffic.
5841 * Added `broadcast' argument to the functions in silcd/server.[ch]
5842 silc_server_create_new_channel[_with_id] to indicate whether
5843 to send New Channel packet to primary router.
5845 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Added new function into the silcd/server.[ch] files:
5848 silc_server_create_new_channel_with_id to create new channel with
5849 already existing Channel ID.
5851 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5852 lib/silccore/silcpacket.h. This packet is used t send list of
5853 Set Mode payloads inside one packet. Server uses this to set
5854 the modes for the channels and clients on those channels, that it
5855 announced to the router when it connected to it. The protocol
5856 specification has been updated accordingly.
5858 * The silc_server_new_channel did not handle the packet coming
5859 from normal server as it normally does not send that. However,
5860 when it announces its channels it does send it. Implemented
5861 the support for that.
5863 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5864 into the file lib/silccore/id.h.
5866 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Fixed memory leaks in the functions silc_idlist_del_client,
5869 silc_idlist_del_channel and silc_idlist_del_server in the file
5870 silcd/idlist.c. All of those leaked like a sieve.
5872 * Fixed some small memory leaks in the client's function
5873 silc_client_notify_by_server.
5875 * Added functions into silcd/server.c: silc_server_announce_clients,
5876 silc_server_announce_channels and silc_server_announce_server.
5877 These functions are used by normal and router server to announce
5878 to its primary router about clients, channels and servers (when
5879 router) that we own. This is done after we've connected to the
5882 These functions effectively implements the following packet types:
5883 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5884 and SILC_PACKET_NEW_ID_LIST.
5886 * Added new functions into the silcd/packet_receive.[ch]:
5887 silc_server_new_id_list, silc_server_new_channel_list and
5888 silc_server_new_channel_user_list to handle the incoming
5889 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5891 * Added support of changing Channel ID in the function
5892 silc_server_replace_id. If the server that announces a channel
5893 to the router already exists in the router (with same name but
5894 with different Channel ID), router is responsible to send
5895 Replace ID packet to the server and force the server to change
5896 the Channel ID to the one router has.
5898 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5899 client that the Channel ID has been changed by the router. The
5900 normal server sends this to the client. Client must start using
5901 the new Channel ID as the channel's ID.
5903 Implemented handling of this new type into lib/silcclient/client.c
5904 into the function silc_client_notify_by_server.
5906 * Added new function silc_idlist_replace_channel_id into the files
5907 silcd/idlist.[ch] to replace the Channel ID.
5909 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Call silc_server_command_identify_check always when processing
5912 the IDENTIFY command in silcd/command.c
5914 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5917 send keepalive packets. The packet can be sent by clients,
5918 servers and routers.
5920 Added function silc_socket_set_heartbeat into the file
5921 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5922 If not set, the heartbeat is not performed. The actual
5923 heartbeat is implemented in the low level socket connection
5924 library. However, application is responsible of actually
5927 Added silc_server_send_heartbeat to send the actual heartbeat
5928 packet into silcd/packet_send.[ch]. Server now performs
5929 keepalive with all connections.
5931 * Added silc_task_get_first function into lib/silcutil/silctask.c
5932 to return the timeout task with shortest timeout. There was a bug
5933 in task unregistration that caused problems. TODO has been
5934 updated to include that task system must be rewritten.
5936 * The client library will now resolve the client information when
5937 receiving JOIN notify from server for client that we know but
5938 have incomplete information.
5940 * Rewrote parts of silc_server_remove_from_channels and
5941 silc_server_remove_from_one_channel as they did not remove the
5942 channel in some circumstances even though they should've.
5944 * Encryption problem encountered in server:
5946 The LEAVE command used to send the Channel Key packet to the
5947 router immediately after generating it. However, the code
5948 had earlier sent Remove Channel user packet but not immediately,
5949 ie. it was put to queue. The order of packets in the router
5950 was that Channel Key packet was first and Remove Channel User
5951 packet was second, even though they were encrypted in the
5952 reverse order. For this reason, MAC check failed. Now, this
5953 is fixed by not sending the Channel Key packet immediately but
5954 putting it to queue. However, this is more fundamental problem:
5955 packets that are in queue should actually not be encrypted
5956 because packets that are sent immediately gets encrypted
5957 actually with wrong IV (and thus MAC check fails). So, packets
5958 that are in queue should be encrypted when they are sent to
5959 the wire and not when they put to the queue.
5961 However, the problem is that the current system has not been
5962 designed to work that way. Instead, the packet is encrypted
5963 as soon as possible and left to the queue. The queue is then
5964 just purged into wire. There won't be any fixes for this
5965 any time soon. So, the current semantic for packet sending
5968 o If you send packet to remote host and do not force the send
5969 (the packet will be in queue) then all subsequent packets to the
5970 same remote host must also be put to the queue. Only after the
5971 queue has been purged is it safe again to force the packet
5974 o If you send all packets immediately then it safe to send
5975 any of subsequent packets through the queue, however, after
5976 the first packet is put to queue then any subsequent packets
5977 must also be put to the queue.
5979 Follow these rules and everything works fine.
5981 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Added new function silc_server_remove_clients_by_server to
5984 remove all client entries from ID list when the server connection
5985 is lost. In this case it is also important to invalidate all
5986 client entires as they hold the invalid server entry. This
5987 fixes fatal bug when server has lost connection and will reconnect
5990 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Made some sanity checks to silc_server_daemonise like to check
5993 whether the requested user and group actually exists.
5995 * Added sanity check to SKE's silc_ske_responder_finish to check
5996 that the public and private key actually is valid.
5998 * Invalidate the client's nickname when receiving Replace ID
5999 packet and the Client ID is being replaced. This means that the
6000 server will query the nickname if someone needs it (client)
6003 * Sort the ID Cache in client library when the ID Cache data
6004 has changed (needs sorting).
6006 * Do not allow for SILC client to create several connections to
6007 several servers. The client does not support windows right now
6008 and generating multiple connections causes weird behaviour.
6010 Irssi-silc client does support windows and can handle several
6011 connections without problems, see: www.irssi.org and SILC plugin.
6013 * Fixed some places where client was added to the IDList. The
6014 rule of thumb is following (in order to get everything right):
6015 If the client is directly connected local client then the
6016 `connection' argument must be set and `router' argument must be
6017 NULL to silc_idlist_add_client function. If the client is not
6018 directly connected client then the `router' argument must
6019 bet set and the `connection' argument must be NULL to the
6020 silc_idlist_add_client function.
6022 * The funtion silc_server_packet_send_local_channel actually did
6023 not check whether the client was locally connected or not. It
6024 does that now. Fixed a bug related to LEAVE command.
6026 * Fixed Remove Channel User payload parsing bug in server's
6027 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6029 * The server's silc_server_save_channel_key now checks also the
6030 global ID list for the channel as it might not be in the local
6031 list. Fixed a bug related to LEAVE command.
6033 * Is this the end of the [<unknown>] buglet that has been lurking
6034 around for a long time? A little for loop fix in server's
6035 silc_server_command_whois_parse that is used by both IDENTIFY
6036 and WHOIS command. At least, this was a clear bug and a cause
6037 of one type of [<unknown>] buglet.
6039 * WHOIS and IDENTIFY commands call the function
6040 silc_server_command_[whois/identify]_check function even if
6041 we are not router server.
6043 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Added --with-gmp configuration option. If set the GMP
6046 is always compiled in the SILC source tree. If not set then
6047 it is checked whether the system has the GMP3 installed. If
6048 it has then the GMP won't be compiled (the system's headers
6049 and library is used), if it doesn't have it then the GMP is
6050 compiled in the SILC source tree.
6052 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Changed RSA private exponent generation to what PKCS #1
6055 suggests. We try to find the smallest possible d by doing
6056 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6057 not security fix but optimization.
6059 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Added new config entry [Identity] to fork the server and run
6062 it as specific user and group. A patch from Bostik.
6064 * Imported Dotconf configuration library into lib/dotconf.
6065 This will be used to create the SILC configuration files later.
6066 It will appear in the distsribution after this commit.
6068 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * A big code auditing weekend happening. Auditing code for
6071 obvious mistakes, bugs and errors. Also, removing any code
6074 Removed files for being obsolete:
6076 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6077 inline in the file lib/silcutil/silcbuffer.h)
6079 o lib/silcutil/silcbufutil.c (the header has inline versions)
6081 Changed code to fix possible error conditions:
6083 o The buffer formatting routines now check that the destination
6084 buffer really has enough space to add the data. This applies for
6085 both buffer formatting and unformatting
6086 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6087 unformatting was changed to accomodate following rules:
6088 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6089 sent to the function while XXX_*STRING will not allocate or copy
6090 the data into the buffer. Instead it sets the pointer from the
6091 buffer into the pointer sent as argument (XXX_*STRING used to
6092 require that the pointer must be allocated already). This change
6093 makes this whole thing a bit more consistent and more optimized
6094 (note that the data returned in the unformatting with XXX_*STRING
6095 must not be freed now). The routines return now -1 on error.
6097 o Tried to find all code that use buffer_format and buffer_unformat
6098 and added return value checking to prevent formatting and
6099 especially unformatting errors and possible subsequent fatal
6102 o Changed ske->x and ske->KEY to mallocated pointers in
6103 lib/silcske/silcske.h. Fixed possible data and memory leak.
6105 o Added return value checking to all *_parse* functions. Fixed
6106 many memory leaks as well.
6108 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6109 so that buffer overflows would not happen. All code now also
6110 checks the return value as it can fail.
6112 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Added reconnection support to server if the normal server looses
6115 its connection to the router (for example if router is rebooted).
6116 The server performs normal reconnection strategy implemented
6117 to the server. Affected file silcd/server.c.
6119 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Added new packet type SILC_PACKET_SET_MODE that is used to
6122 distribute the information about changed modes (for clients,
6123 channels and clients channel modes) to all routers in the
6124 network. Updated the protocol specification accordingly.
6126 Added functions into silcd/packet_send.c and
6127 silcd/packet_receive.c: silc_server_send_set_mode,
6128 silc_server_set_mode.
6130 Added new files silcmode.[ch] into lib/silccore that implements
6131 the encoding and decoding of Set Mode Payload. Added new type
6132 SilcSetModePayload. Moved the definitions of different modes
6133 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6135 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6137 * Oops, a little mistake in server's connection authentication
6138 protocol. The protocol is not ended with FAILURE but with
6139 SUCCESS if the authentication is Ok. :) Affected file is
6142 * Implemented NICK_CHANGE notify handling in server in the file
6143 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6144 the local clients on the channel. After the changing nickname
6145 in router environment snhould work and the [<unknown>] nickname
6146 should appear no more.
6148 The silc_server_replace_id function that receives the Replace ID
6149 payload now sends the NICK_CHANGE notify type also in the file
6150 silcd/packet_receive.c
6152 * Changed WHOIS and IDENTIFY command to support the maximum amount
6153 of arguments defined in protocol specs (3328 arguments). This
6154 fixed a bug that caused problems when there were more than three
6157 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Added extra parameter, command identifier, to the
6160 silc_client_send_command so that explicit command identifier
6163 Changed that ID list routines uses specific command identifier
6164 when sending WHOIS/IDENTIFY requests to the server so that they
6165 can be identified when the reply comes back.
6167 Affected files lib/silcclient/command.[ch],
6168 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6170 * Added `sender' argument to silc_server_packet_send_to_channel
6171 to indicaet the sender who originally sent the packet to us
6172 that we are now re-sending. Ignored if NULL. Affected file
6173 silcd/packet_send.[ch].
6175 * Added some server statistics support in silcd/server_internal.h
6176 SilcServerStatistics structure and around the server code. Also
6177 send some nice statistics information when client is connecting
6180 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Fixed channel ID decoding in server's JOIN command reply in
6183 silcd/command_reply.c
6185 * Fixed braodcasting of replace ID payload to not to send it if
6186 we are standalone server in silcd/packet_receive.c.
6188 * Fixed all channel message sending routines to not to send
6189 packets to clients that has router set, since they are routed
6190 separately in the same function earlier. Affects file
6191 silcd/packet_send.c and all channel packet sending functions.
6193 * In USERS reply, res_argv[i] are not allocated, the table
6194 is allocated. Thus changed that free the table, not its
6197 * In server's whois_check and identify_check if the client is
6198 locally connected do not send any WHOIS commands - they are not
6201 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Fixed some minor bugs in client when sending WHOIS command. The
6204 arguments was in wrong order.
6206 * Removed statis function add_to_channel from server in
6207 silcd/command.c that was previously used with the joining but
6210 * Tested USERS command in router environment successfully with two
6211 routers, two servers and two clients.
6213 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Reorganized the USERS command and command reply in client library
6216 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6217 When the command is given by user we register a pending command
6218 callback that will reprocess the command after the reply has been
6219 received from the server. When reprocessing the packet we then
6220 display the information. Thus, the USERS information is displayed
6221 now in the command callback instead of in the command reply
6222 callback. The processing of the command is same as previously
6223 when server has sent the command reply in the JOINing process.
6225 * Added to USERS command in silcd/command_reply.c to join the client,
6226 we didn't use to know about, to the channel after we've created
6227 a client entry for it. Also, for clienet we did know already still
6228 check whether it is on the channel or not and add it if not.
6230 * Removed silc_server_command_join_notify as the function and its
6233 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Changed the client's pending command handling to the same as the
6236 server's pending command handling. It is also now possible to
6237 execute command reply functions from other command reply
6238 function as the function callbacks for commands and command
6239 replies are one and same. The pending commands are not static
6240 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6241 in client connection context. Thus, pending commands are server
6242 connection specific as it is convenient.
6244 Changed the function silc_client_command_pending and
6245 silc_client_command_pending_del and added new function
6246 silc_client_command_pending_check. Removed the
6247 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6250 * Added cmd_ident, current command identifier, to the client
6251 connection context in lib/silcclient/client.h to keep track on
6252 command identifiers used in command sending. Client's command reply
6253 function handling now supports the mandatory command identifiers.
6255 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6256 funtions in client to fully support pending command callbacks.
6258 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6259 as one of the arguments to the application in the command reply
6262 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6263 before first releasing SILC but came back. Now it is removed again
6264 and should come back nomore. The FORWARDED flag was used only
6265 by the JOINing procedure by forwarding the command packet to router.
6266 Now, the JOINing procedure has been changed to more generic (due
6267 to various router environment issues) and FORWARDED is not needed
6268 anymore for anything. The protocol specification is yet to be
6271 Now, removed silc_server_packet_forward from server and the flag
6272 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6274 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6276 * Renamed NAMES command to USERS command. The NAMES was named that
6277 due to historical reasons. Now it is renamed. Also, rewrote
6278 parts of the USERS command. The nickname list is not sent anymore
6279 by the server. Only Client ID and mode lists are sent in the USERS
6280 command. Changed this also to the protocol specification.
6282 The client now resolves the names and stuff after it receives
6283 the USERS list from the server when joining to the channel.
6285 * WHOIS and IDENTIFY commands has been changed to support multiple
6286 Client ID's per command. One can now search for multiple users
6287 in the network by sending only one WHOIS or IDENTIFY command.
6288 Changed the code and the protocol specifications.
6290 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6291 uses silc_server_command_whois_parse to parse the request. */
6293 * If normal server, do not parse the WHOIS and IDENTIFY requests
6294 before sending it to the router. Saves some time.
6296 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Fixed JOIN command on client library. Wrong number of arguments
6299 used to crash the client.
6301 * Added silc_server_channel_has_global function to check whether
6302 channel has global users or not.
6304 * Added silc_server_channel_has_local function to check whether channel
6305 has locally connected clients on the channel.
6307 * The silc_server_remove_from_one_channel now checks whether the
6308 channel has global users or not after given client was removed from
6309 the channel. It also checks whether the channel has local clients
6310 on the channel anymore. If it does not have then the channel entry
6311 is removed as it is not needed anymore.
6313 * The silc_server_notify now checks on JOIN notify whether the joining
6314 client is one of locally connected or global. If it is global then
6315 the channel has now global users on the channel and that is marked
6316 to the channel entry. Also, it now saves the global client to
6317 global list who is joining and JOINs it to the channel. This is
6318 for normal server, that is.
6320 Changed silc_server_send_notify_on_channel,
6321 silc_server_packet_relay_to_channel and
6322 silc_server_packet_send_to_channel check if we are normal server
6323 and client has router set (ie. global client) do not send the
6324 message to that client, as it is already routed to our router.
6326 * Implemented LEAVE notify type handling in silc_server_notify
6329 * Tested LEAVE command in router environment successfully. Tested
6330 with two routers, two servers and two clients.
6334 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6336 * Implemented SIGNOFF notify type handling in silc_server_notify
6339 * silc_server_remove_id now removes the client entry from all channels
6340 it has joined and thusly sends SIGNOFF notify type.
6342 * Rewrote the NAMES list generation in server by removing two excess
6343 loops. The lists are created now inside one loop.
6345 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * silc_server_remove_channel_user checks now also global list
6348 for channel and client.
6350 * silc_server_new_channel_user checks now both local and global
6351 list for channel and client. Fixed a bug in client id decoding.
6352 Used to decode wrong buffer.
6354 * silc_server_channel_message checks now both local and global
6355 list for channel entry.
6357 * Tested channel joining (hence JOIN) in router environment
6358 successfully. Tested with two routers, two servers and two
6361 * Tested channel message sending in router environment successfully.
6363 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Added silc_server_save_channel_key into server.[ch] to save the
6366 received channel key in Channel Key payload processing. It is
6367 also used in JOIN command reply handling.
6369 Equivalent function silc_client_save_channel_key added into
6370 client.[ch] into client library.
6372 * Changed JOIN command reply to send information whether the channel
6373 was created or not (is existing already) and the channel key
6374 payload. Changed protocol specs accordingly.
6376 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6377 the request was sent by ID and not by nickname. Crashed on
6380 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6383 now correctly save the received data.
6385 * silc_server_free_sock_user_data now notifies routers in the
6386 network about entities leaving the network.
6388 At the same time implemented functions silc_server_remove_id
6389 and silc_server_send_remove_id to receive and send REMOVE_ID
6390 packets. The packet is used to notify routers in the network
6391 about leaving entities. The ID removed will become invalid in
6394 * Added function silc_idlist_del_server into server. Removes and
6395 free's server entry from ID list.
6397 * silc_server_private_message function now checks, if we are router,
6398 that the destination ID really is valid ID, naturally.
6400 * In router when NEW_ID packet is received (for new client) the
6401 hash of the Client ID is saved in the ID Cache but the
6402 client->nickname is set to NULL, instead of putting the hash
6405 IDENTIFY command now also checks that client->nickname must be
6406 valid. If it is not if will request the data from the server who
6407 owns the client. Added new function
6408 silc_server_command_identify_check.
6410 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6411 to set the command to already allocated Command Payload.
6413 * Tested private message sending in router environment with two
6414 routers, two servers and two clients. Fixed minor bugs and now
6417 * Fixed segfault from client's NAMES command. Used to crash if
6420 * Forwarded packets must not be routed even if it is not destined
6421 to the receiver. Changed server code comply with this.
6423 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Added `require_reverse_mapping' boolean value to ServerParams
6426 structure. If TRUE (not default) the server will require that
6427 the connecting host has fully qualified domain name.
6429 If the reverse mapping is not required and hostname could not be
6430 found the IP address is used as hostname.
6432 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Implemented version string checking to both client and server.
6435 The check is incomplete currently due to the abnormal version
6436 strings used in development version of SILC.
6438 * Changed all command functions in server to use the new
6441 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Changed char *data to unsigned char *data in ID Cache system to
6444 support binary data as ID Cache data. Changed code to support
6445 binary data in lib/silccore/idcache.c.
6447 * Renamed silc_server_packet_relay_command_reply to
6448 silc_server_command_reply as it is normal packet receiving
6449 function. Rewrote the function to accept command replys for
6450 servers and not only for clients.
6452 * Mark remote router always as registered server if we are connecting
6453 to it. Otherwise, commands sent by the router to us are ignored.
6455 * All ID List find routines now returns the ID Cache Entry pointer
6456 as well if requested.
6458 * WHOIS command works now in router environment, tested with two
6459 routers, two servers and two clients.
6461 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6462 in router environment (as it is almost equivalent to WHOIS) but
6463 hasn't been tested thoroughly. Added new functions:
6465 silc_server_command_identify_parse
6466 silc_server_command_identify_send_reply
6467 silc_server_command_identify_from_client
6468 silc_server_command_identify_from_server
6470 * Disabled route cache adding because adding two different ID's with
6471 same IP replaces the old cache entry thus giving wrong route.
6472 The entry->router->connection is always the fastest route anyway
6473 so route cache may not be needed. Of course, new routes maybe
6474 established after receiving the ID when the entry->router->connection
6475 might not be anymore the most optimal.
6477 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * Add route cache for received ID for fast routing.
6481 * Added silc_server_packet_route to route received packet on router
6482 that is not destined to us.
6484 * Renamed silc_server_get_route to silc_server_route_get.
6486 * Added id_string and id_string_len fields into SilcServer to
6487 include encoded ServerID for fast comparing without excess
6488 encoding of the ID's.
6490 * Cleaned up WHOIS command on server side. Added following static
6493 silc_server_command_whois_parse
6494 silc_server_command_whois_check
6495 silc_server_command_whois_send_reply
6496 silc_server_command_whois_from_client
6497 silc_server_command_whois_from_server
6499 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6500 arguments in command replies. All command functions should be
6501 updated to use this macro.
6503 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Minor typo fixes on command reply handling on server.
6507 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6509 * Added silc_server_command_add_to_channel internal routine to add
6510 the client to the channel after router has created the channel and
6511 sent command reply to the server.
6513 * Added generic silc_server_send_command to send any command from
6516 * Use static buffer with ID rendering instead of duplicating data.
6518 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Fixed a channel user mode bug when joining to a channel server gave
6521 everybody channel founder rights, oops.
6523 * We mark ourselves as the router of the incoming server connection
6524 if we are router ourselves. This way we can check in some packet
6525 sending functions whether it is locally connected server. For
6526 incoming router connections we put NULL.
6528 * For router sending packets locally means now always sending the
6529 packet cell wide; to local clients and local servers. For normal
6530 server sending packet locally means sending it to only local
6533 * Fixed the JOIN command to really work in router environment. If the
6534 channel is created it is always created by the router. Router is
6535 also responsible of making the initial joining to the channel,
6536 sending JOIN notify to the sending server and distributing
6537 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6538 does not exist server doesn't do anything else but forward the
6539 command to the router which performs everything.
6541 * Added silc_server_send_channel_key function to send the Channel Key
6544 * Added silc_server_create_channel_key to create new channel key. The
6545 channel key is now re-generated everytime someone joins or leaves
6546 a channel, as protocol dictates. Note: channel->key_len is the
6549 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6552 packet_receive.[ch] to separate packet sending and receiving
6553 routines. The server.[ch] now includes everything else including
6554 actual packet processing (writing and reading data) and other
6557 Renamed silc_server_private_message_send_internal to
6558 silc_server_send_private_message. The routine is still though
6559 used only to relay private messages as server does not send
6560 private messages itself.
6562 Renamed silc_server_new_channel to silc_server_create_new_channel
6563 and added new function sicl_server_new_channel that handles the
6564 incoming New Channel packet. Added also new sending function
6565 silc_server_send_new_channel to send New Channel Payload.
6567 * Added new function silc_server_notify to process incoming notify
6568 packet to the server/router. Server may then relay the notify
6569 to clients if needed.
6571 * Added new function silc_server_new_channel_user to process incoming
6572 New Channel User packet. Router will redistribute the packet and
6573 send JOIN notify to its local clients and locally connected servers
6574 if needed. Normal server will send JOIN notify to its local client
6575 on same channel when received this packet. Added also corresponding
6576 sending function silc_server_send_new_channel_user to sent the
6579 * Added boolean route argument to send_notif_to_channel and
6580 packet_send_to_channel functions to attempt to route the packet
6581 if it is TRUE and send only locally if it is FALSE.
6583 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * silc_server_replace_id now broadcasts the received replace ID
6586 packet if it is not broadcast packet already. The router must
6587 broadcast to inform other routers about changed ID.
6589 * Added backpointer to server's router into SilcServer context in
6590 silcd/server_internal.h.
6592 * Fixed silc_server_packet_broadcast to send correct broadcast
6595 * The channel key is now distributed to the local client as soon
6596 as it is received from the router (in router environment) so that
6597 no other packet may be sent for the channel until client has
6600 * silc_server_remove_channel_user now broadcasts the received
6601 Remove Channel User packet if it is not broadcast packet already.
6602 The router must broadcast to inform other routers about removed
6605 * Added users field into SilcPacketContext that is a reference count
6606 of the context. One can increase the reference count by calling
6607 silc_packet_context_dup which is now changed to just increase the
6608 reference count instead of duplicating the data. The reference
6609 count is decresed by calling silc_packet_context_free that will
6610 free the data after the reference count hits zero.
6612 For now on the packet context and everything allocated into it
6613 (including the raw packet from network) must be freed by calling
6614 the new silc_packet_context_free function. Added also new function
6615 silc_packet_context_alloc that must be used now to allocate the
6616 context. This also means that if a routine is asynchronous from
6617 silc_[client/server]_packet_parse_type the packet context must
6618 be duplicated by calling silc_packet_context_dup. Otherwise it
6619 gets free'd after silc_[client/server]_packet_parse_type returns.
6620 Also, one must remember that if packet is duplicated then its
6621 reference count must be decresed by calling the free function as
6622 many times as it was duplicated.
6624 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6625 from both client and server.
6627 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Made joining to a channel working in router environment.
6631 * Cleaned up JOIN command on server side and create function
6632 silc_server_command_join_channel internal routine to make the
6635 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Changed silc_command_pending list to SilcDList. Also, added
6638 `ident' field to SilcServerCommandPending structure to identify
6639 the reply and to call correct callback.
6641 Added silc_server_command_pending_check function to replace the
6642 corresnponding macro. The silc_command_pending list is not
6645 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6646 to set identifier to previously allocated Command Payload. It
6647 is used to set identifier for command when resending Command
6650 * Added silc_command_payload_encode_payload to encode Command
6651 Payload buffer from SilcCommandPayload structure.
6653 * Added silc_argument_payload_encode_payload to encode Argument
6654 payload buffer from SilcArgumentPayload structure.
6656 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Changed WHOIS command to support router connection on server side.
6659 The whois request is always sent to router unless the server is
6660 standalone server. After server has received the reply from the
6661 router will it send the reply to the client.
6663 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6664 broadcast received broadcast packet. The function is used only
6665 by router. The broadcast packet is always sent to the router's
6668 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6669 render given ID to printable string, for log files for example.
6671 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Made basic router to router connections working. At least they
6674 can now connect to each other but nothing really works the way
6675 they are supposed - yet.
6677 * Added new initiator token to RouterConnection configuration
6678 file in silcd/serverconfig.[ch]. It is used to tell whether we
6679 are the initiator to the remote router or whether we'll expect
6680 the other end to connect.
6682 * Moved registering of listener task to silc_server_init, hence
6683 the server starts listenning as soon as it is run, even if it
6684 does not have connections to other routers. Let's see how well
6687 * Changed default connection retry timeouts for more suitable in
6690 * Removed cipher and such arguments from silc_idlist_add_client
6691 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6692 Added new function silc_idlist_add_data to add the keys and stuff
6695 * Added SilcIDListData structure and added it to SilcClientEntry
6696 and SilcServerEntry as their first field in the structure. This
6697 way we can explicitly cast the ID entries to the SilcIDListData
6698 structure and get common data for the entries. In past, we had
6699 to first check what type of connection it is and then cast it to
6700 correct ID entry type. Now, we can directly cast the opaque
6701 pointer to the SilcIDListData (no matter what ID entry it actually
6702 is) and get the data needed.
6704 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6706 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6707 in some circumstances even if threre were timeout tasks, though not
6708 IO tasks, but tasks anyway. Now fixed.
6710 * Defined SilcServerConnection structure to hold connection specific
6711 stuff about directly connected servers and routers. The definition
6712 is currently in silcd/server_internal.h. I thought about having
6713 a bit more important role fro this struct but for now it is used
6714 only when connecting to other server (or router actually).
6716 * Added connecting retry support in server when connecting to
6717 router(s). The retry feature implement exponential backoff
6718 algorithm. Also, added SilcServerParams structure to hold default
6719 parameters for server. For now, it include these retry settings
6720 and are hard coded. After server is moded to be as Silc Server
6721 Library this structure will be more important.
6723 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Changed client librarys channel->clients table to SilcList and
6726 changed code accordingly.
6728 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Changed client's channel table to SilcList and changed code
6731 accordingly. Also changed SilcChannelClientEntry to include back-
6732 pointer to the channel so that client entry can use that structure
6733 as list as well and we have fast cross-reference to the channel.
6734 This change dramatically decreased the complexity of channel
6735 handling with client entry and vice versa (removed one extra
6736 loop when searching for channel entry from many functions).
6738 * Changed server->sim from table to SilcDList and changed code
6741 * NAMES command can now be used from user interface. It will show
6742 the user list on the channel, neatly.
6744 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6745 Code now saves realname of the user if it becomes available.
6747 * Renamed configure.in to configure.in.pre and made ./prepare
6748 script to automatically add correct version string to
6749 configure.in which it creates from configure.in.pre.
6751 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * NAMES command reply now shows users mode with the nickname when
6756 * Moved silc_client_ch[u]mode[_char] functions from
6757 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6758 place sucks, they are utility functions and should be in some
6761 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6763 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6766 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Added TRQ (efficient deque and list library) into lib/trq. This is
6771 a very good list library that is currently used in the SILC. Defined
6772 SilcList API over the library because I didn't like the API very
6773 much. See lib/trq/silclist.h for the API and examples of how to
6774 use the API. Fixed various places in the code to use the new
6775 SilcList API. The SilcList is meant for lists that has a structure
6776 already defined as a list. It is not suitable to add just some
6777 context to the list (in TRQ, the context is the list actually).
6779 So, I defined SilcDList that can be used for the purpose where
6780 predefined list structure does not exit. This can be used as
6781 such list. Now some context just can be added to the SilcDList.
6782 Currently this list is not used in the SILC just yet, though there
6783 are a lot places where this can replace dynamically allocated
6784 tables and I will fix these places, later, to use SilcDList.
6785 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6786 and use TRQ internally).
6788 Also fixed some annoying warning messages that the original TRQ
6789 code generated. Also minor changes to TRQ's Makefile.in.
6791 * Added support for querying by Client ID to both WHOIS and
6792 IDENTIFY commands into server, as required by the protocol.
6794 * Removed method function pointers from SilcBuffer structure. They
6795 weren't used to anything and just increased the context size for
6796 no good reason. This change also made silc_buffer_alloc and
6797 silc_buffer_free functions inline functions.
6799 * Disabled command flooding detection support until it's fixed so
6800 that it accepts commands in but does not execute them more than once
6803 * Added silc_net_localhost(), to return local hostname, into
6804 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6805 that must be initialized before calling silc_client_init.
6807 * Added new function: silc_server_send_notify_on_channels to send
6808 notify messages to all channels client has joined. It is assured
6809 that the message is sent only once per client.
6811 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6812 lib/silcutil/silcutil.[ch] as silc_format function. The new
6813 function is generic and is used by server as well, not only by
6814 the logging routines.
6816 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6817 the provided version string was not acceptable. Added new function:
6818 silc_ske_check_version into lib/silcske/silcske.h. The function
6819 must be implemented by the application (client or server) and it
6820 does not reside in the SKE library. The function checks the version
6821 string remote end sent.
6823 * Added back pointers (to opaque context and to SilcSocketConnection)
6824 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6826 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6827 duplicate packet context structure.
6829 * Changed `notify' client operation to send same arguments as client
6830 receives from server except for ID's. ID's are mapped to correct
6831 ID entry and that is returned. Also, if channel entry is not sent
6832 by server but the notify is for channel the channel entry is sent
6833 to application (otherwise application doesn't know that it is for
6834 channel (library gets it from packet's Destination ID)).
6836 * Added silc_client_remove_from_channels into client library to
6837 remove a client from all channels it has joined to. Used when
6838 received SIGNOFF notify from server. Added also new function
6839 silc_client_replace_from_channels to replace old ID entry with
6840 new ID entry on all channels. Used when received NICK_CHANGE
6843 * Fixed ID Cache list handling in silc_idlist_get_client in
6844 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6845 to get (or query) client by ID.
6847 * Updated TODO list.
6849 * Added connection authentication status message defined by the
6850 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6851 support for these into the code in client and server side.
6853 * Added generic function silc_client_send_command to send any command
6854 with variable argument list. Application should use this function
6855 to send commands if the command functions provided by the library
6856 does not suite for the application's user interface needs.
6858 * Added new `failure' client operation. Application is notified about
6859 received failure packet if client is executing a protocol. In this
6860 case the protocol's execution has failed.
6862 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6863 is required by the protocol.
6865 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6866 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6869 * Added status flag to SilcSKE object to indicate realtime status
6870 of the SKE protocol.
6872 * Application receives now exactly same command reply arguments as
6873 the library receives from server. However, if ID is received the
6874 corresponding ID entry is returned to the application (eg. Client
6875 ID is mapped to correct SilcClientEntry entry and that is returned).
6876 Changed command_reply client operation due to this change.
6878 * Changed all ID's in commands and in command replys as ID Payloads.
6879 Change affected both client and server side codes.
6881 All ID's sent in SILC network (with execption of ID's in SILC
6882 Packet header) are sent in ID Payload to support variable length
6885 * Server now notifies nick changes and notifies all clients on
6886 the channels about the new nickname (about the new Client ID,
6889 * Implemented CMODE command to change channel modes. Supports all
6890 channel modes defined by the protocol specs except ban and invite
6891 lists. (Also, private channel key mode is supported but support for
6892 setting private channel key in client is missing, thus, this mode
6893 has no effect on client side (except that server requires that the
6894 client uses private channel key and normal channel traffic does not
6897 Also, invite mode works per se, but INVITE command does not work
6898 yet correctly, so you can set channel as invite only channel but
6899 inviting clients to the channel does not work (it is yet to be
6900 thought what's the best way to do it).
6902 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6903 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6904 Implemented CUMODE command to change user's mode on the channel.
6905 Supports all modes defined by the protocol specs.
6907 * Added NAMES command reply to return users modes on the channel.
6909 * Removed unnecessary and slow ciphers from lib/silccrypt.
6911 * Set SO_KEEPALIVE option to connection sockets by default.
6913 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6915 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6916 redefined the Notify Payload into protocol specs.
6918 * Added silc_id_payload_parse_id to get ID directly from raw
6921 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6923 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6924 accept searching by Client ID as well.
6926 * Added support for LEAVE and SIGNOFF notify types in client library.
6928 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6929 to parse ID Payload from raw data.
6931 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Added flags parameter into silc_ske_assemble_security_properties
6934 function in lib/silcske/silcske.[ch].
6936 * Changed notify client operation to fit better for notify messages
6937 sent by server. The notify payload received from server is now
6938 passed to the application (after parsing it to SilcNotifyPayload).
6939 It is application's responsibility to retrieve the arguments
6940 from the payload and show the message the way it wants. The message
6941 sent by server is implementation specific.
6943 * Changed public keys to comply with the protocol specification.
6944 Old public keys are not supported anymore and are not compatible.
6946 * Removed nickname from Channel Payload as the latest draft removed
6947 it. The client must resolve the nickname from the NAMES command
6948 reply received when it joined the channel.
6950 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6952 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Fixed some errors in protocol specification drafts.
6956 * Created lib/silccore/silcnotify.c to implement Notify Payload
6957 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6958 generic payloads described by protocol specifications. The file
6959 includes implementations for ID Payload and Argument Payload.
6961 * Changed Command Payload implementation to use the new Argument
6962 Payload. Changed command_xxxx_payload to command_payload_xxxx
6963 to comply with SILC coding conventions.
6965 * Added suppport for Argument Payload handling in Notify Payload
6966 implementation as protocol requires it. Added the new support
6967 into server and client lib as well.
6969 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * Added support for multiple nicknames on same channel. [n] is
6972 added locally to the nickname if there are more than one same
6973 nicknames on the channel.
6975 * Server now sends all nicknames that matched WHOIS request.
6976 Client also shows the list received from server.
6978 * Added TOPIC command to client side. User can now set and show
6979 current topic on channel.
6981 * Added MOTD command to client and server. Also, server sends the
6982 motd when client connects to the server.
6984 * Changed version strings to comply ISO 8601.
6986 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Fixed protocol error handling in client library. It should now
6989 cope even if the SKE fails for some reason.
6991 * Made new protocol specification drafts for submitting to IETF.
6993 * Implemented TOPIC command to server in silcd/command.c.
6995 * Added two new notify types into lib/silccore/silcnotify.h:
6996 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6997 notify nickname change and topic setting/change on a channel.
6999 * API change of command_reply operation in client library. The
7000 application gets now the status type received from server as well.
7002 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7004 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7006 * Cras fixed and optimized the packet handling even further and
7007 it should work now. Minor change to the prototype of function
7008 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7010 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7012 * Added new function into lib/silcutil/silcschedule.[ch]:
7013 silc_schedule_with_fd to select() a specified fd. The function
7014 returns after timeout expires or data arrives or goes. The
7015 function is used by packet routines to wait that all data is
7016 received from network.
7018 * Fixed data reading from network in lib/silccore/silcpacket.c.
7019 The code now assures that all data is read from the fd and then
7020 continues packet processing. This was a bug fix since the code
7021 used to drop some data in some circumstances.
7023 * Added new function into lib/silcclient/client.[ch]:
7024 silc_client_start_key_exchange to start key exchange after
7025 connection has been established to server. The code internally
7026 now uses this funtion but its main purpose was to provide it
7027 for applications that perform their own connecting. After
7028 application has created a connection it merely calls this
7029 function to start the key exchange between client and server.
7030 The library takes care of everything else after that.
7032 Updated also lib/silcclient/README to explain the usage of
7035 * Do not send to application information that connection has
7036 been established. Application gets notified it by connect
7039 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7041 * Applied cras's patch to add silc_schedule_one function. The
7042 function runs scheduler once and returns.
7044 * Fixed the scheduler after cras messed it up. The timeout
7045 handling works now as it's supposed to work.
7047 * Added into lib/silccore/ silcnotify.h to include notify
7048 message types support. Changed silc_server_send_notify*
7049 functions, in server.[ch], to support those new notify types.
7050 Added the support for the notify types into client library,
7051 as well. Added new notify client operation into ops.h in
7054 * Changed silc_server_packet_send_to_channel to send normal
7055 packets instead of just channel message packets. The function
7056 is now used to send the notify packets to channels. It is not
7057 used to send channel message packets anymore, as server never
7060 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7061 va_arg()s as it seems to require it nowadays. I guess, if SILC
7062 is compiled with older va_arg() the new code should work anyway.
7064 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * Splitted core library. Core library (lib/silccore) includes
7067 now only SILC protocol specific core (and common) components.
7068 Created new utility library (lib/silcutil) that includes more
7069 generic purpose stuff. The stuff for util library was taken
7070 from the old core library. This was minor and easy split.
7072 * Created SILC Client Library (lib/silcclient) that includes
7073 implementation of the SILC client without user interface. This
7074 was major move from silc/ directory. The code has been changed
7075 so that it is transparent towards the user interface. The
7076 silc/ directory includes now the same user interface as before
7077 and it uses the new client library. Read lib/silcclient/README.
7078 Basicly, the client library performs everything else related
7079 to SILC except user interface handling. Also, configuration
7080 files are considered to be part of user interface and library
7081 does not handle them.
7083 This change also changed a lot of structures, function naming etc.
7084 Most important change was that SilcClientWindow object was
7085 renamed to SilcClientConnection in the client library. Created
7086 also new file lib/silcclient/ops.h. Also added new files
7087 silc/local_command.[ch] and silc/client_ops.[ch].
7089 All these changes were made to make it easier for user interface
7090 designers to create what ever user interface for the SILC client
7093 It is also expected that the server will be moved to lib
7094 directory as well and SILC Server Library will be created;
7095 sometimes in the future.
7097 * Removed Local commands from lib/silccore/silccommand.h as
7098 they are application specific and new client library does not
7099 handle any of those anymore.
7101 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7102 old client implementation in silc/.
7104 * Added support for callback functions in SILC_LOG_* macros.
7105 Application can now set its own callbacks that will be called
7106 instead of using the default functions that will always print
7107 the debug messages to stderr (or stdout). Also, debugging can
7108 now be disabled by setting silc_debug to FALSE and re-enabled by
7109 setting it to TRUE. Note, that logging will still work even
7110 if debugging is disabled.
7112 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7113 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7114 silc_log_reset_debug_callbacks.
7116 * To enable debugging in silc client one must give now -d
7117 option on command line.
7119 * Changed silc_schedule_init to automatically allocate task queues
7120 if they are not allocated before calling it.
7122 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Added GMP 3.1 into math library.
7126 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7129 a channel in SILC network. The packet is used by servers and
7130 routers to notify other routers that user has left a channel.
7131 This little feature was missing until now. Added the feature
7132 to protocol specification as well.
7134 Added functions: silc_server_send_remove_channel_user and
7135 silc_server_remove_channel_user into server.[ch].
7137 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7138 lib/silccore/silcpacket.h. However, they are not implemented
7141 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7143 * Fixed joining to a channel and sending channel messages
7144 between server and router. The channel message sending should
7145 now work inside a cell.
7147 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7149 * Fixed the private message sending between server and router.
7150 The private message sending should now work inside a cell.
7152 * Added silc_server_replace_id into server.[ch] to replace
7153 existing ID in the SILC network.
7155 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7156 and silc_idlist_replace_server_id into idlist.[ch] in server.
7158 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * Fixed the server to server connections. Server can again now
7161 connect to router. Router to router connections probably does
7164 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Added dynamic protocol registering support. Now protocols can
7167 registered and unregistered on the fly. Patch by cras.
7169 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Added lib/contrib directory to hold routines that some platforms
7172 don't have but are needed by SILC.
7174 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7175 into lin/contrib to provide getopt() and getopt_long() for
7176 those who don't have it.
7178 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Added AWAY command to client. When away message is set and
7181 client receives a private message packet the client automatically
7182 replies to the sender with the away message.
7184 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7185 bug seemed to be the cause of recent problems when compiling
7188 * Added version detection support to SKE protocol specification
7189 and added the new changes to the SKE implementation as well.
7190 There were other minor changes in the SKE protocol as well.
7192 Many changes in lib/silcske/silcske.[ch] and in
7193 lib/silcske/payload.[ch].
7195 * Added ^U functionality, clear input line. Patch from cras.
7197 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Mainly small bugfixes on core library. Fixed some debugging
7200 logging and buffer overflow in silclog.c.
7202 * Updated config.sub and config.guess on the distribution tree.
7204 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Added command lagging support in server. Client may execute
7207 commands now only once in two seconds.
7209 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7211 * Optimized packet reception. MAC computation and checking is now
7212 also more optimized. A lot previously duplicated code is now
7213 used as generic by both client and server.
7215 * Fixed key pair generation in clientutil.c
7217 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7219 * Added into lib/silccore/silcbufutil.[ch] new function;
7220 silc_buffer_realloc.
7222 * Moved generic packet sending/encryption functions to
7223 lib/silccore/silcpacket.[ch] from client and server. Some
7224 rewriting of the functions.
7226 * Moved all generic packet reception/decryption functions to
7227 lib/silccore/silcpacket.[ch] from client and server. The
7228 packet processing is now much cleaner in both client and server.
7229 These were major changes in both client and server.
7231 * Created many common functions in server to do packet sending.
7232 Previously code were duplicated a lot, this has been removed
7235 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Rewrote major parts of the ID cache system. Don't know
7238 whether it is better now or not but at least the API is more
7241 * Major rewrite on ID cache stuff on client because of the ID
7242 cache API changes. Added idlist.c to client.
7244 * Also major rewrite on ID cache stuff on server as well.
7245 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7246 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7247 in hand, instead they are all put into the ID cache system now.
7248 All server_idlist_* routines uses ID cache now instead of
7249 traversing its own lists (those lists does not exist anymore).
7250 SilcIDList though still exists. Also, SilcXXXEntry's are
7253 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Finally made the SKE implementation compliant to the protocol
7256 specification. All mp integers are now binary encoded as
7257 opposed being HEX encoded.
7259 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7262 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7263 functions: silc_[encode/decode]_pem. Also added function
7264 silc_encode_pem_file to PEM encode with newlines ('\n') for
7267 * SILC public keys are now encoded either PEM or binary. Same
7268 option is for private keys as well. By default private keys
7269 are binary encoded and public keys PEM encoded. Silly HEX
7270 encoding were removed.
7272 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7273 function to create fingerprints.
7275 * Fixed a bug in SHA1; does not change the original data anymore.
7277 * Partly implemented INFO command on client and server side.
7278 Fixed CLEAR command. Changes to SERVER command; show current
7279 server(s) when giving command without arguments. Added
7280 VERSION command to client.
7282 * Added check to server that unregistered connections cannot
7283 execute commands (unless it is specificly allowed).
7285 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7287 * Fixed screen refresh.
7289 * Fixed channel joining bug from client. On some circumstances
7290 client tried to join to a channel it had already joined.
7292 * Added public key verification process into client's protocol.c.
7293 The client now verifies the public key from user and saves
7294 it into ~./silc/serverkeys/ directory.
7296 Added into: clientutil.[ch]: silc_client_verify_server_key.
7298 * Changed SKE protocol's silc_ske_initiator_finish function
7299 to accept callback function that verifies the received public
7300 key. Removed old silc_ske_verify_public_key function.
7302 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7305 silc_pkcs_private_key[_data]_set.
7307 * Made the password and public authentication more cleaner in
7308 server's protocol.c.
7310 * Removed historic and obsolete protocol `channel_auth' from
7311 both client and server.
7313 * Removed wrong way of sending command status messages from
7314 server to client in server's command.c. The old way violated
7315 protocol specification.
7317 Changes to silccore/silccommand.[ch]: removed
7318 silc_command_encode_status_payload -> not needed anymore,
7319 changed silc_command_encode_payload_va to accept extra
7320 argument on variable argument list. The argument type must
7321 now be provided to the function. Also, added new function:
7322 silc_command_encode_reply_payload_va which is same as
7323 normal command_encode_payload_va except command status type
7324 is provided as extra argument.
7326 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Added ~./silc directory handling. The directory includes the
7329 public and private keys for the client.
7331 Added silc_client_check_silc_dir, silc_client_create_identifier
7332 and silc_client_load_keys.
7334 * Implemented SILC protocol compliant public key. Added public
7335 and private key saving to and loading from files.
7337 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7338 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7339 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7340 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7341 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7343 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7344 silc_pkcs_load_[public/private]_key.
7346 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Added silc_server_get_route (route.[ch]) to get connection
7349 data for the fastest route for given ID.
7351 * Implemented INVITE command on client and server. The command
7352 were re-defined in the SILC Protocol Specification and the
7353 implementation now complies with the specification.
7355 * Implemented PING command on client and server.
7357 * Implemented NAMES command on client and server. The server side
7358 supports currently only normal server not router server yet.
7359 Some changes to NAMES definition in SILC protocol specification.
7361 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7363 * Implemented LEAVE command on client and server.
7365 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7366 again. This change was made to the protocol as well. Server
7367 should not violate the protocol specification anymore.
7369 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7372 was tested. SOCKS4 was not but should work anyway.
