5 hash public keys and compare public keys in hash table. Affected
6 file lib/silcutil/silcutil.[ch].
8 * Added support for specifying multiple public keys for Client
9 connection section in server configuration file. This makes it
10 possible to accept multiple public keys from same host, or to
11 make a section that accepts any incoming host, and have the
12 accepted public keys listed in the section.
14 Added functions silc_sever_[find/get]_public_key, added the
15 support for this actually to all connection sections but only
16 the Client section is currently allowed to specify multiple

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

278 algorithm parts and created new file silcalgs.conf, that
279 is now included from the example_silcd.conf.in.
281 * Optimized the silc_server_connect_to_router_second to take
282 the connection configuration object from the SilcServerConnection
283 object instead of finding it during the connecting phase.
284 Added the configuration object to SilcServerConnection struct.
285 Affected files silcd/server_internal.h, server.c.

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

369 * Fixed the file transfer's key agreement payload to include
370 zero port also if the hostname is NULL because it could not
373 Call file transfer monitor callback now also if error occurs
374 during key agreement protocol.
376 Changed the silc_client_file_send interface to return the
377 SilcClientFileError instead of session id. The session ID
378 is returned into pointer provided as argument.
380 Check that the file exists locally before sending the
381 file transfer request at all.
383 Affected file lib/silcclient/client_ftp.c, silcapi.h.

395 file lib/silcutil/silclog.c.
397 * Fixed the channel message payload decryption in the function
398 silc_channel_message_payload_decrypt to not modify the original
399 buffer before it is verified that the message decrypted
400 correctly. Otherwise, next time it is called with correct
401 channel key it won't encrypt since the payload is corrupted.
402 Affected file lib/silccore/silcchannel.c.
404 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

447 users list to SilcHashTable. The affected files are
448 lib/silcclient/idlist.[ch].
450 * Fixed a bug in hash table tarversing. While the hash table
451 is traversed with SilcHashTableList the table must not be
452 rehashed. It is now guaranteed that auto rehashable tables
453 are not rehashed while tarversing the list. Also defined that
454 silc_hash_table_rehash must not be called while tarversing
455 the table. Added function silc_hash_table_list_reset that must
456 be called after the tarversing is over. The affected files are
457 lib/silcutil/silchashtable.[ch].
459 * Changed all hash table traversing to call the new
460 silc_hash_table_list_reset in server and in client library.
462 * Added function silc_client_on_channel to return the
463 SilcChannelUser entry if the specified client entry is joined

474 lists correctly. Affected file silcd/command.c.
476 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
478 * When sending JOIN command to router for processing the
479 sender's old command identifier was not saved back to the
480 sender's command context, fixed now. The affected file is
483 * Create the key in JOIN command of the router did not return
484 the channel key, added check for this. Affected file is
487 * Fixed a channel ID update bug in JOIN command reply. Do
488 not directly upgrade the ID but call the function
489 silc_idlist_replace_channel_id if the ID was changed.
490 Affected file silcd/command_reply.c.
492 * Fixed memory leaks from command calling if it would fail.
493 Affected file silcd/command.c.

520 functions. Affected file silcd/server.c.
522 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
523 which ID was changed. This way the router will send the
524 user list for the channel again, and server won't be in
525 desync in some rare circumstances. Affected file is
526 silcd/packet_receive.c.
528 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

559 * Fixed the SERVER_SIGNOFF notify handling on normal server
560 not to save the history information for clients. Same was
561 fixed earlier in remove_clients_by_server function, but not
562 here. Affected file silcd/packet_receive.c.
564 * Raised the default connection-retry count from 4 to 7 in
565 server. Affected file silcd/server.h.
567 * Cancel any possible reconnect timeouts when we start the
568 key exchange. Affected file silcd/server.c.
570 * Do not reconnect on connection failure when SCONNECT was
571 given. Affected files silcd/server.[ch].
573 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
577 * Fixed the NICK command to always give the unformatted
578 nickname to the one giving the NICK command. If unformatted
579 nickname is cached already it will be formatted and the
580 local entry will always get the unformatted nickname.
581 Affected file lib/silcclient/idlist.c.
583 * Fixed some double frees from client library commands.
584 Affected file is lib/silcclient/command.c.
586 * Fixed CUMODE command in server to assure that no one can
587 change founder's mode than the founder itself, there was a
588 little bug. Affected file silcd/command.c.
590 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Removed the SilcClientCommandDestructor from the client
593 libary, it is not needed anymore. Affected files are
594 lib/silcclient/silcapi.h, command[_reply].[ch],
595 client_notify, idlist.c.
597 * Fixed GETKEY command to first resolve client, and then
598 resolve the server only if the client was not found, instead
599 of resolving both at the same time. Affected file is
600 lib/silcclient/command.c.
602 * Added silc_client_start_key_exchange_cb and lookup the
603 remote hostname and IP address before starting the key
604 exchange with server. The affected file is
605 lib/silcclient/client.c.
607 * The server's public key is now saved using the IP address
608 of the server and not the servername for the filename.
609 The hostname public key filename is checked as an fall back
610 method if the IP address based filename is not found.
612 Fixed the GETKEY command to save the fetched server key
615 Print the remote server's hostname now when new key is
616 received during connection process. Affected file is
617 irssi/src/silc/core/client_ops.c.
619 * Return always our own public key to the client if it asks
620 for it with GETKEY command. Affected file silcd/command.c.
622 * Removed the use_auto_addr variable from default config
623 file since it was in wrong section. Affected file is
626 * Fixed TOPIC_CHANGE notification to not route it when it
627 was sent using silc_server_send_notify_to_channel function.
628 Affected file silcd/command.c.
630 * Fixed silc_server_send_notify_kicked to send the kicker's
631 Client ID also, it was missing. Affected files are
632 silcd/command.c, silcd/packet_send.[ch].
634 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Do not save client history information in SERVER_SIGNOFF.
637 Fixes the bug in normal server that it does not detect
638 the client becoming valid after the server becomes back
639 online. Affected file silcd/server_util.c.
641 * Added `sock_error' field into the SilcSocketConnection
642 context. When error occurs during socket operation (read
643 or write) the error is saved. Added also new function
644 silc_socket_get_error to return human readable socket error
645 message. Affected files are lib/silcutil/silcsockconn.[ch],
646 lib/silcutil/unix/silcunixsockconn.c, and
647 lib/silcutil/win32/silcwin32sockconn.c.
649 * The server now prints the socket error message in the
650 signoff for client. Affected file silcd/server.c.
652 * Fixed the `created' channel information sending from router
653 to server in JOIN command. Checks now whether the channel
654 really was created or not and set it according that.
656 Fixed the JOIN command to use the client entry's current
657 ID during the joining procedure instead of the one it sent
658 in the command (it is checked though), since it can change
659 between the packet processing and command processing, and
660 would just case unnecessary pain in the client end. Affected
661 file silcd/command.c.
663 * Fixed a channel key payload sending to use correct channel
664 ID when the server was forced to change the channel's ID by
665 router. Router sent the key payload with the old Channel ID.
666 Affected file silcd/packet_receive.c.
668 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
670 * Call silc_server_save_channel_key only if the key payload
671 was provided in the JOIN command's command reply. Affected
672 file silcd/command_reply.c.
674 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
676 * Fixed silc_mp_sizeinbase to return the value correctly with
677 MPI. Affected file lib/silcmath/mp_mpi.c.
679 * Fixed the stop_server signal to correctly stop the scheduler
680 and gracefully stop the server when SIGTERM or SIGINT signals
681 are received. Affected file silcd/silcd.c.
683 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
685 * Simple handling of TERM and HUP signals. Also added some log
686 flushing call around. Affected file is
689 * Fixed small bugs in silclog.c. Now buffering output will take
690 effect after 10 seconds since startup: This will ensure that
691 no important startup messages are lost. Also output redirection
692 will preserve original format ([Date] [Type] message).
693 Affected file is lib/silcutil/silclog.c.
695 * Added two options to the config file, in the logging section:
696 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
697 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
699 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Do not print the warning about log files not being initialized
702 more than once to avoid excess logging. Affected file is
703 lib/silcutil/silclog.c.
705 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
706 the SIM copying in make install in Makefile.am.pre.
708 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
710 * Rewritten silclog APIs. Globally interesting changes follows:
711 silc_log_set_files() changed to silc_log_set_file().
712 silc_log_set_callbacks() changed to silc_log_set_callback().
713 ROBOdoc documented silclog header file.
714 SilcLogCb now returns bool to wether inihibit the default
715 handler or not (to keep the old behaviour return always TRUE).
716 The new APIs should also fix the problem of the
717 silcd_error.log file that was written in the current directory.
720 Log files streams will remain opened after silc_log_set_file()
721 call, means less CPU usage notably on high traffic servers.
722 File streams are now full buffered, and flushed to the disk
723 every 5 minutes, lesses HD activity and CPU usage.
724 Messages can be redirected, allowing admins to configure
725 one single logfile for all server messages.
726 the silc_log_quick global variable to activate fast-logging.
727 Affected files lib/silcutil/silclog.[ch]
729 * Changed some code to conform new silclog APIs. Affected
730 files are doc/example_silcd.conf.in, silcd/server.c
731 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
734 * Fixed a memory leak that could occur in some situations.
735 Affected file silcd/serverconfig.c.
737 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Added the silc_client_del_client to remove the client from
740 all channels as well. Affected file lib/silcclient/idlist.c.
742 * Fixed the client library to correctly remove the client
743 from all channels when the client entry is being destroyed.
744 Affected file lib/silcclient/client_notify.c, command.c.
746 * Added auto-nicking support to the client library. If the
747 applicatio now sets client->nickname it will be sent to the
748 server after connecting by the library. This way for example
749 SILCNICK (or IRCNICK) environment variables will have effect
750 and always change the nickname automatically to whatever
751 it is wanted. Affected file lib/silcclient/client.[ch].
753 * Renamed silc_server_command_bad_chars to the
754 silc_server_name_bad_chars and moved it to the
755 silcd/server_util.[ch]. Added also new function
756 silc_server_name_modify_bad to return nickname that
757 includes bad characters as new nickname without those
758 bad characters. This check and modify is now used in
759 silc_server_new_client when the username is initially set
760 as nickname, so it must be checked to be valid nickname.
761 Affected file silcd/packet_receive.c.
763 * The nickname length is now taken from the packet for real
764 and not trusted to strlen() since it clearly can return
765 wrong length for nickname including bad characters. This
766 also applies to channel names. Affected file silcd/command.c.
768 * Removed the lib/silcsilm/modules directory. Modules are now
769 compiled into the lib/silcsim. Fixed the copying of the
770 modules to follow symbolic links in Makefile.am.pre.
772 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Fixed silc_string_regexify list creation. Fixes bugs with
775 BAN and INVITE commands in server. The affected file is
776 lib/silcutil/unix/silcunixutil.c.
778 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
780 * Removed the command destructor entirely from the server's
781 command and command reply routines. It is not needed, and
782 its usage was buggy and caused crashes. Affected files are
783 silcd/command[_reply].[ch].
785 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
787 * Cancel protocol and NULL sock->protocol if timeout
788 occurred during protocol. Affected file silcd/server.c.
790 * Cancel protocol timeouts always before calling the final
791 callback, to assure that after final callback is called
792 no other state will be called for the protocol anymore.
793 Affected file silcd/protocol.c.
795 * Print error log if incoming connection configuration could
796 not be found. Affected file silcd/server.c.
798 * Fixed JOIN command to correctly save the founder mode
799 to the client on normal SILC server, when the channel
800 was created by the router. Affected file silcd/command.c.
802 * Fixed LIST command (hopefully) to send correct reply
803 packets. Affected file silcd/command.c.
805 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
807 * The silc_packet_receive_process now returns FALSE if the
808 read data was invalid packet, and TRUE if it was ok.
810 The server now checks that if unauthenticated connection
811 sends data and its processing fails the server will close
812 the connection since it could be a malicious flooder.
814 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
816 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Make sure the warning about error opening a log file is
819 printed only once and not everytime it fails (produces
820 too much useless log). Affected file lib/silcutil/silclog.c.
822 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
824 * Made the silc_server_daemonise() function more readable.
825 Affected file silcd/server.c.
827 * Pid file is now optional, the user may comment it out from
828 the config file. Removed define SILC_SERVER_PID_FILE, we
829 don't need a default any longer. Affected file
830 configure.in.pre, lib/Makefile.am.pre.
832 * Make some use of the pid file. The server now dies at startup
833 if it detects a valid pid file on his path. The server would
834 die anyway in this circumstance, because of the bind() failure.
835 Affected file silcd/silcd.c.
837 * No longer compiling lib/dotconf.
839 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Fixed JOIN command parsing not to crash. Affected file
842 lib/silcclient/command.c.
844 * Fied the NICK_CHANGE notify to add the new client entry
845 even it is resolved. This removes an <[unknown]> nick
846 thingy bug in the client. Affected file is
847 lib/silcclient/client_notify.c.
849 * Do not try to allocate 0 bytes (efence does not like it)
850 in lib/silccore/silccomand.c when encoding payload.
852 * Do not take IRCNICK as nickname in Irssi SILC client since
853 it is not possible to set nickname before hand connecting
854 the server (TODO has an entry about adding auto-nicking
857 * Changed the silc_server_command_pending to check whether
858 there already exists an pending entry with the specified
859 command, command identifier and pending callback. This is
860 to fix IDENTIFY and WHOIS related crashes that may register
861 multiple pending commands with same identifier. Affected
862 file silcd/command.c.
864 * Fixed the server to reconnect to the router even if it
865 was already reconnecting and EOF was received. This to
866 fix a possibility that the server wouldn't ever try to
867 auto-reconnect to the router. Affected file silcd/server.c.
869 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Fixed the server's password authentication to use the
872 length of the locally saved password, and not the one
873 sent in the packet. Affected file silcd/protocol.c.
875 * Fixed same password authentication problem in the
876 Authentication Payload handling routines in
877 lib/silccore/silcauth.c.
879 * Yet another password authentication problem fixed with
880 channel password handling in silcd/command.c.
882 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
884 * If first character of string in silc_parse_userfqdn is '@'
885 then do not parse it. Affected file is
886 lib/silcutil/silcutil.c.
888 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Fixed minor bug in IDENTIFY command reply sending, which
891 caused various weird problems during JOIN when it was
892 resolving names for users. Affected file silcd/command.c.
894 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
896 * Fixed the IDENTIFY command reply sending to chech better valid
897 clients. It was possible to send incomplete list of replies.
898 Affected file silcd/command.c.
900 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
902 * Added silc_client_command[s]_[un]register functions now to
903 dynamically register the commands in client library. Removed
904 the static table of commands. This allows the client library
905 to call commands without causing the application to know about
906 what commands library has called.
908 Removed the INFO command reply kludge to detect when the command
909 was called by library. Now library use its own command reply
910 function for INFO command.
912 Added function silc_client_command_call to call a command.
913 Application can use it to call command, not access the structure
916 Now all commands that are sent by the client library (not
917 explicitly sent by application) use own command reply functions.
919 Affected files around lib/silcclient/ and in
920 irssi/src/silc/core/.
922 * Fixed the WHOIS command reply sending to chech better valid
923 clients. It was possible to send incomplete list of replies.
925 Fixed the WHOIS and IDENTIFY to send the request to router
926 if normal server did not do it and did not find any results.
928 Affected file silcd/command.c.
930 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
932 * Moved the internal data from SilcClient context into its
933 own file, not accesible to application. Affected files
934 lib/silcclient/client.h and lib/silcclient/client_internal.h,
935 and other files in client library.
937 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Added doc/examples installation target in Makefile.am.pre.
942 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
944 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
945 commands the found client entry will be removed from the
946 cache, after notifying application about the error. Affected
947 file lib/silcclient/command_reply.c.
949 * Changed the /MSG to check for exact nickname user gave, and
950 not let `nick' match `nick@host' if it is only one found. Now,
951 user must type the exact nickname (like nick@host2) even if
952 there are no more than one same nicks found. This is to avoid
953 a possibility of sending nickname to wrong nickname since
954 `nick' could match `nick@host'. Affected file is
955 irssi/src/core/silc-servers.c.
957 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
959 * Do not print "you are now server operator" or similar when
960 giving /away command. Affected files are
961 irssi/src/silc/core/client_ops.c, silc-servers.h.
963 * Made the silc_server_command_pending_error_check to send
964 the same command reply payload it received back to the
965 original sender of the command. This way all arguments
966 that was received by the server will be received by the
967 client too. Affected file silcd/command.c.
969 * Added the silc_idcache_add to return the created cache entry
970 to a pointer. Affected file lib/silccore/silcidcache.[ch].
972 * Add global clients to expire if they are not on any channel.
973 This is because normal server will never know if they signoff
974 if they are not on any channel. The cache expiry will take
975 case of these entries. This is done by normal servers only.
976 The affected files are silcd/command_reply.c,
977 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
979 * If server receives invalid ID notification for WHOIS or
980 IDENTIFY and the ID exists in the lists, it is removed.
981 Affected file silcd/command_reply.c.
983 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
984 in client then client entry that it matches is searched and
985 the nickname is printed on the screen for user. Affected
986 file irssi/src/silc/core/client_ops.c.
988 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
990 * Use cache entry expire time in the LIST command reply to
991 purge old entries from the cache after the LIST command
992 reply has been received. This way we don't have non-existent
993 entries in the cache for too long. Affected file is
994 silcd/command_reply.c.
996 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
998 * If we are normal server, and we've not resolved client info
999 in WHOIS or IDENTIFY from router, and it is global client,
1000 we'll check whether it is on some channel. If it is not
1001 then we cannot be sure about its validity and will resolve it
1002 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1003 file silcd/command.c.
1005 * Search channel by name (if possible) rather than by ID
1006 in IDENTIFY command's command reply. Affected file is
1007 silcd/command_reply.c.
1009 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1011 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1012 Updated specs and implemented it. Affected file silcd/command.c,
1013 silcd/packet_send.c and silcd/packet_receive.c.
1015 * Implemented the <founder auth> payload handling in the JOIN
1016 command. If provided all conditions for channel joining
1017 except requirement to provide correct passphrase can be
1018 overrided by the channel founder. Updated the protocol specs.
1019 Affected file silcd/command.c.
1021 Added support for founder auth in JOIN command in client
1022 library. Fixed the parsing of the JOIN command now to support
1023 all options as they should be. The affected file is
1024 lib/silcclient/command.c.
1026 * Optimized the WHOIS and IDENTIFY commands to send the request
1027 to router only if it includes nicknames or other names. If
1028 they include only IDs then check the local cache first before
1029 routing. Affected file is silcd/command.c.
1031 * Added channels topic announcements. Affected file is
1032 silcd/packet_receive.c and silcd/server.c.
1034 * Fixed the silc_server_send_notify_topic_set to really destine
1035 the packet to channel. Affected file silcd/packet_send.c.
1037 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1038 library. Affected file lib/silcclient/client_notify.c.
1040 * Added UMODE announcements. Affected file silcd/server.c.
1042 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Memory leak fixes in:
1046 lib/silcutil/silcsockconn.c
1047 lib/silcske/silcske.c
1048 lib/silcske/groups.c
1050 lib/silccrypt/silcpkcs.c
1051 lib/silccore/silccommand.c
1052 lib/silccore/silcidcache.c
1057 * ROBOdoc documented the lib/silcske/groups.h file and a
1058 bit changed the interface for better.
1060 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1062 * Update the client entry context in the ID cache after
1063 nick change. Affected file lib/silcclient/command.c.
1064 Fixes the CUMODE command when regaining founder privileges,
1065 and a little WHOIS problem.
1067 * Fixed silc_net_gethostbyname to correctly call the
1068 inet_ntop. Affected file lib/silcutil/silcnet.c.
1070 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1072 * Added IPv6 support checking to the configure.in.pre, added
1073 also --enable-ipv6 option to override the check. Affected
1074 file configure.in.pre.
1076 * The silc_thread_create now calls the start function
1077 directly if threads support is not compiled in. Removes
1078 ugly #ifdef's from generic code. Affected files are
1079 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1081 * Added silc_net_gethostby[name/addr]_async to asynchronously
1082 resolve. Affected files are lib/silcutil/silcnet.[ch].
1084 * Added support for rendering IPv6 based server, client and
1085 channel IDs. Affected file lib/silcutil/silcutil.c.
1087 * Added support for creating IPv6 based server IDs. Affected
1088 file is silcd/serverid.c.
1090 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1092 * Added silc_net_gethostby[addr/name] into the
1093 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1094 routines. Added silc_net_is_ip[4/6]. Affected file is
1095 lib/silcutil/unix/silcunixnet.c. All routines that take
1096 address as argument now supports both IPv4 and IPv6 addresses.
1098 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1100 * Fixed LIST command reply sending in server. Affected file
1103 * Server now sends the kicker's client ID in the KICK notify
1104 to the kicked client. Affected file silcd/command.c.
1106 * The client library now parses the kickers client ID and
1107 UI displays it. Affected files lib/silcclient/client_notify.c
1108 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1110 * Made all payload parsing function prototypes consistent.
1111 They all take now const unsigned char * and uint32 pair as
1112 the payload data instead of SilcBuffer. Changes all around
1113 the source tree. Other unsigned char* -> const unsigned char*
1114 changes around the tree as well.
1116 * Optimized SFTP client and server packet sending not to
1117 allocate new buffer for each packet but to recycle the
1118 first allocated buffer. Affected files are
1119 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1121 * Optimized the SFTP client to use SilcList instead of
1122 SilcDList for requests, because it is faster. Affected file
1123 is lib/silcsftp/sftp_client.c.
1125 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1126 into lib/silccore/silcid.[ch].
1128 Renamed silcpayload.[ch] into silcargument.[ch].
1130 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * If client entry is deleted with active key agreement
1133 session, abort the session.
1135 The silc_client_abort_key_agreement now calls the completion
1136 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1138 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1141 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * Don't use __restrict in older GCC's. Affected file is
1144 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1146 * silc_net_localhost now attempts to reverse lookup the
1147 IP/hostname. Affected file lib/silcutil/silcnet.c.
1149 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1150 command. It can be used to gain founder privileges at
1151 the same time when joining the channel.
1153 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1154 kicker's client ID as well. Updated protocol specs.
1156 Defined that the server must send SILC_COMMAND_IDENTIFY
1157 command reply with error status to client who sent
1158 private message with invalid client ID.
1160 Updated the protocol specification.
1162 * Added silc_server_send_command_reply to send any
1163 command reply. Affected file silcd/packet_send.[ch].
1165 * Added silc_id_payload_encode_data to encode ID payload
1166 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1168 * The server now send IDENTIFY command reply with error
1169 status if client ID in private message is invalid. Affected
1170 file silcd/packet_receive.c.
1172 * Save the server key file with server's IP address in
1173 the filename instead of hostname. The affected file is
1174 irssi/src/silc/core/client_ops.c.
1176 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1181 * Added libtool support for compiling shared objects in
1182 lib/silcsim. Affected file configure.in.pre and
1183 lib/silcsim/Makefile.am. Original patch by cras.
1185 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Pid file configuration, and server's config file fixes
1188 patch by toma. Updated CREDITS file.
1190 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Fixed silc_client_channel_message to not try to decrypt
1193 the message twice if it resolved the destination client
1194 information. This could cause of dropping one channel
1195 message. Affected file lib/silcclient/client_channel.c.
1197 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1200 lib/silcclient/client.c. This function is used when the SILC
1201 Client is run under some other scheduler, or event loop or
1202 main loop. On GUI applications, for example this may be
1203 desired to used to run the client under the GUI application's
1204 main loop. Typically the GUI application would register an
1205 idle task that calls this function multiple times in a second
1206 to quickly process the SILC specific data.
1208 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1210 * Fixed silc_server_drop() for dropping the supplementary
1211 groups as well, this could cause a security hole on some
1214 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1216 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1219 * Write PID file after dropping privileges. Added -F option
1220 to run server on foreground. A patch by debolaz.
1221 Affected files silcd/server.c, silcd/silcd.c.
1223 * Fixed MOTD to return the MOTD file server name. Affected
1224 file silcd/command.c.
1226 * Added INFO command reply handling to the Irssi SILC Client.
1227 Affected file irssi/src/silc/core/client_ops.c.
1229 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1231 * Fixed the silc_idcache_list_* routines to really support
1232 the dynamic list. Fixes a crash. Affected file is
1233 lib/silccore/silcidcache.c.
1235 * Fixed the LIST command reply to really call LIST command's
1236 pending callbacks. Affected file silcd/command_reply.c.
1238 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Update conn->local_entry->nickname after giving NICK
1241 command. Affected file lib/silcclient/command.c.
1243 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1245 * Added the [pid] option to the silcd configuration file
1247 Affected files: serverconfig.[ch] and silcd.c
1249 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1251 * Save fingerprint in WHOIS command reply in server.
1252 Affected file silcd/command_reply.c.
1254 * Fixed NICK commands pending callback registration.
1255 Affected file lib/silcclient/command.c.
1257 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * Use ++server->cmd_ident when sending commands in server,
1260 instead of random number. Affected file silcd/command.c.
1262 * Fixed GETKEY command reply to call actually GETKEY pending
1263 command callbacks. Affected file silcd/command_reply.c.
1265 * A bit stricter check for nicknames. Check for same nickname
1266 in NICK command also. Affected file silcd/command.c.
1268 * Do not call INFO command everytime client ID changes, only
1269 during first connecting. Affected file lib/silcclient/client.c.
1271 * Set the new nickname only after successful command reply for
1272 NICK command is returned by server. Affected file
1273 lib/silcclient/command.c.
1275 * Remove nicknames from nicklist during server_signoff notify.
1276 Should fix /NAMES bit more. The affected file is
1277 irssi/src/silc/core/silc-channels.c.
1279 * Added `fingerprint' field to the SilcIDListData in the
1280 silcd/idlist.h to hold the fingerprint of the client's
1283 Send the fingerprint of the client's public key in WHOIS
1286 Affected files silcd/command.c, and silcd/idlist.[ch].
1288 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1289 create fingerprint from given data.
1291 * Show the fingerprint of the client's public key in WHOIS.
1292 Affected files irssi/src/module-formats.[ch] and
1293 irssi/src/silc/core/client_ops.c.
1295 * Format the multiple same nicknames also during JOIN and
1296 NICK_CHANGE notifys. Affected file is
1297 lib/silcclient/client_notify.c.
1299 * Do not print error on screen for invalid private message
1300 payload since it can come if someone is sending private
1301 messages with wrong key. Affected file
1302 lib/silccore/silcprivate.c.
1304 * Fixed multiple concurrent /PING crash. Affected file
1305 lib/silcclient/command.c.
1307 * Changed the wrong ID encoding. All IP addresses must be
1308 in MSB first order in encoded format. They were encoded
1309 wrong and was in LSB format. Affected files are
1310 silcd/serverid.c, lib/silcutil/silcutil.c.
1312 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1314 * Call the `connect' client operation through the scheduler
1315 in case of error. Affected file lib/silcclient/client.c.
1317 * Call the `failure' client operation even if the error
1318 occurred locally during a protocol. Affected file is
1319 lib/silcclient/protocol.c.
1321 * Added support of sending LIST command to router from normal
1322 server. This way normal server can get list of all channels
1323 in the network too. Fixed the channel list sending in the
1324 server too. Affected files are silcd/command.c, and
1325 silcd/command_reply.[ch].
1327 * Added silc_server_update_channels_by_server and
1328 silc_server_remove_channels_by_server. They are used during
1329 disconnection of primary router and in backup router protocol.
1330 Affected file silcd/server_util.[ch], silcd/server.c and
1331 silcd/server_backup.c.
1333 * Fixed channel adding to global list in IDENTIFY command
1334 reply in server. Affected file silcd/command_reply.c.
1336 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * If the incoming packet type is REKEY or REKEY_DONE process
1339 that packet always synchronously. Fixes yet another MAC
1340 failed error on slow (dialup) connections. Affected file
1341 lib/silcclient/client.c and silcd/server.c.
1343 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Call check_version SKE callback for initiator too. Affected
1346 file lib/silcske/silcske.c.
1348 * Implemented fix for security hole found in the SKE that was
1349 fixed in the specification few days back; the initiator's
1350 public key is now added to the HASH value computation.
1351 Added backwards support for the old way of doing it too, for
1352 old clients and old servers. Affected file is
1353 lib/silcske/silcske.c.
1355 * Enabled mutual authentication by default in SKE. If initiator
1356 is not providing mutual authentication the responder will
1357 force it. This will provide the proof of posession of the
1358 private key for responder. The affected files are
1359 lib/silcclient/protocol.c and silcd/protocol.c.
1361 * Do not cache anymore the server's public key during SKE.
1362 We do mutual authentication so the proof of posession of
1363 private key is done, and if the server is authenticated in
1364 conn auth protocol with public key we must have the public
1365 key already. Affected file silcd/protocol.c.
1367 * Added new global debug variable: silc_debug_hexdump. If
1368 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1369 file lib/silcutil/silclog.[ch].
1371 * Fixed compilation warning due to char * -> const char *.
1372 Affected files lib/silcutil/silcnet.h, and
1373 lib/silccore/silcauth.[ch].
1375 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Fixed CMODE command when new channel key was created. If
1378 the creation failed the old key was removed. Next time giving
1379 same command would crash the server since the old key was
1380 freed already. Affected file silcd/command.c.
1382 * Fixed the silc_server_announce_get_channels to not crash
1383 on reconnect. Affected file silcd/server.c.
1385 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Added silc_log_set_debug_string function to set a regex
1388 string to match for debug output. Only the function names,
1389 or filenames matching the given debug string is actually
1390 printed. This way it is possible to filter out those debug
1391 strings that user is not interested in.
1393 Fixed a bug in silc_string_regexify.
1395 Affected files lib/silcutil/silclog.[ch], and
1396 lib/silcutil/unix/silcunixutil.c.
1398 * Changed the -d options in both server and Irssi SILC client
1399 to take the debug string as argument. Affected files
1400 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1402 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Added silc_hash_babbleprint to create a Bubble Babble
1405 Encoded fingerprint. The encoding is developed by Antti
1406 Huima (draft-huima-babble-01.txt), and it creates human
1407 readable strings out of binary data. Affected file
1408 lib/silccrypt/silchash.[ch].
1410 * Print the babble print now in addition of fingerprint as well
1411 in Irssi SILC client. Affected files are
1412 irssi/src/fe-common/silc/module-formats.[ch],
1413 irssi/src/fe-common/silc/core/client_ops.c.
1415 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Fixed a security problem found in SKE. The initiator's
1418 public key too is now added to the HASH hash value creation
1419 which is signed by the responder to create the SIGN value.
1420 This will prevent anyone in the middle to lie to the responder
1421 about the initiator's public key. If this is done now, the
1422 man in the middle will get caught. Updated the protocol
1425 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Better installation directory handling. Configure module
1428 paths and other paths automatically to example_silc* files
1429 in doc/. A patch by toma.
1431 * Fixed compiler warning from MPI library, and from SILC RNG.
1434 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1435 It can be configured with ./configure. A patch by toma.
1437 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Find correct make to use in prepare-clean. A patch by
1440 toma. Affected file prepare-clean.
1442 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1444 * Added irssi variables use_auto_addr, auto_bind_ip,
1445 auto_bind_port and auto_public_ip.
1447 * Changed the interface for silc_client_send_key_agreement
1448 in lib/silcclient/silcapi.h
1452 irssi/src/silc/core/silc-core.c
1454 lib/silcclient/silcapi.h
1455 irssi/src/silc/core/silc-channels.c
1456 lib/silcclient/client_keyagr.c
1459 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Added silc_pkcs_public_key_compare to compare two
1462 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1464 * Check that the client who set the founder mode on the
1465 channel is the same client that is giving the founder
1466 mode to itself. It is done by comparing the saved public
1467 key (it is saved even in the authentication is passphrase).
1468 Affected file silcd/command.c.
1470 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Do not process packet for disconnected socket connection.
1473 Affected file lib/silccore/silcpacket.c.
1475 * Process the DISCONNECT packet through scheduler in the
1476 client library. Affected file lib/silcclient/client.c.
1478 * Fixed the silc_client_packet_parse to not to increase
1479 the packet sequence number if the conn->sock and the
1480 current socket connection is not same. This can happen
1481 for example during key agreement when the conn includes
1482 multiple socket connections (listeners). Affected file
1483 lib/silcclient/client.c.
1485 * The sender of the file transfer request now provides also
1486 the pointer (listener) for the key exchange protocol. If
1487 the listener cannot be created then it sends empty key
1488 agreement and lets the receiver provide the listener.
1490 Added `local_ip' and `local_port' arguments to the
1491 silc_client_file_send. If they are provided they are used,
1492 if not then it will attempt to find local IP address, if
1493 not found or bind fails then the remote client will provide
1496 Affected files are lib/silcclient/client_ftp.c and
1497 lib/silcclient/silcapi.h.
1499 * Extended the FILE SEND command to support defining the
1500 local IP and port for key exchange listener. They are
1501 optional. Affected file irssi/src/silc/core/silc-servers.c.
1503 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Defined to WHOIS command reply the sending of fingerprint
1506 of the client's public key (if the proof of posession of the
1507 corresponding private key is verified by the server).
1508 Updated to the protocol specification.
1510 * Added support of receiving the client's public key's
1511 fingerprint in command reply in client library. Affected
1512 file is lib/silcclient/command_reply.c, and
1513 lib/silcclient/idlist.[ch].
1515 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Do not send over 128 chars long nickname to the server
1518 in NICK command. Affected file lib/silcclient/command.c.
1520 * Do not send over 256 chars long channel names to the server
1521 in JOIN command. Affected file lib/silcclient/command.c.
1523 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Assure that silc_server_close_connection cannot be called
1526 twice for same socket context. Affected file is
1529 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Send error message to application if opening file for
1532 writing during file transfer fails. Affected file is
1533 lib/silcclient/client_ftp.c.
1535 Remove all file transfer sessions for a client that we're
1536 removing from ID cache.
1538 Affected file is lib/silcclient/client_ftp.c.
1540 * Fixed silc_net_addr2bin to return correct address. Affected
1541 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1543 * Fixed file transfer session removing on signoff notify.
1544 Affected file irssi/src/silc/core/silc-servers.c.
1546 * Added the SilcClientFileError to be returned in the monitor
1547 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1548 Affected file lib/silcclient/silcapi.h.
1550 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Fixed a crash in silc_client_ftp_free_sessions and
1553 silc_client_ftp_session_free_client. Affected file
1554 lib/silcclient/client_ftp.c.
1556 * Added `disabled' field in the SilcChannelEntry in the server
1557 to indicate if the server entry is disabled. Affected file
1558 silcd/idlist.h, silcd/command[_reply].c.
1560 * SILC server adds now /var/run/silcd.pid everytime it is
1561 started. Affected file silcd/silcd.c.
1563 * Added silc_server_packet_send_clients to send a packet to
1564 the provided table of client entries. Affected file
1565 silcd/packet_send.[ch].
1567 * Fixed a crash in client resolving in client_prvmsg.c in
1568 client library. Affected file lib/silcclient/client_prvmsg.c.
1570 * Do not actually remove the client directly from ID cache
1571 during SERVER_SIGNOFF, but invalidate it. This way we
1572 preserve the WHOWAS info for the client. Affected file
1573 silcd/server_util.c.
1575 * Fixed SERVER_SIGNOFF notify handling in the server. The
1576 server is now able to process incoming SERVER_SIGNOFF notify
1577 for a server that it doesn't even know about. It will remove
1578 the clients provided in the notify. Affected file
1579 silcd/packet_receive.c.
1581 * Check for partial packet in data queue after every packet that
1582 was found from the queue. Return and wait for more data if
1583 there is partial data in queue. Affected file is
1584 lib/silccore/silcpacket.c.
1586 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Added SilcClietFileError enum to indicate error in
1589 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1590 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1591 Affected files lib/silcclient/silcapi.h and
1592 lib/silcclient/client_ftp.c.
1594 * Check that newsize in silc_buffer_realloc is larger than
1595 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1597 * Added better monitor of file transfers. It now monitors
1598 key agreement protocol during the file transfer too. Added
1599 error reporting too. Affected files
1600 irssi/src/silc/core/silc-servers.c,
1601 irssi/src/fe-common/silc/module-formats.[ch].
1603 * Wrote a help file for FILE command.
1605 * Added silc_rng_global_get_byte_fast to get not-so-secure
1606 random data as fast as possible. Random data is read from
1607 /dev/urandom if available and from the SILC RNG if not
1608 available. It is used in padding generation. Affected file
1609 lib/silccrypt/silcrng.[ch].
1611 * All packets in client library are now processed synchronously.
1612 Optimized packet processing a lot. Affected file
1613 lib/silcclient/client.c.
1615 * All server connection packets are processing synchronously
1616 now in server, to optimize packet processing. Affected file
1619 * Include files are installed now only in Toolkit distribution
1620 if make install is given. Affected files: all Makefile.am's.
1622 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Assure that silc_client_notify_by_server_resolve does not
1625 resolve the client information multiple times. If it cannot
1626 be found by the first it cannot be found at all. Affected
1627 file lib/silcclient/client_notify.c.
1629 * Fixed WHOWAS command reply calling. Affected file
1630 lib/silcclient/command_reply.c.
1632 * Removed all references to silc_idlist_get_client from the
1633 Irssi SILC client since that call is internal call used by
1634 the library. The Irssi SILC client will use now client
1635 retrieval functions found in silcapi.h.
1637 * Fixed a bug in resolving nickname info before sending
1638 private message. It used freed memory. Affected file
1639 irssi/src/silc/core/silc-servers.c.
1641 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1660 * Added silc_net_localip to return local host's IP address.
1661 Affected file lib/silcutil/silcnet.[ch].
1663 * If key exchange or rekey protocol is active for a connection
1664 parse all packets syncronously since there might be packets
1665 in packet queue that we are not able to process without first
1666 processing packets before them. Affected file silcd/server,
1667 lib/silcclient/client.c.
1669 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1670 whether library should continue processing the packet.
1671 Affected file lib/silccore/silcpacket.h.

1717 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1718 is incomplete and is being resolved, it won't be resolved
1721 Make sure also that USERS command reply does not resolve
1722 twice information. Affected file is
1723 lib/silcclient/command_reply.c.
1725 Make sure that silc_client_get_clients_by_list does not
1726 resolve twice same information.
1728 * Check for valid client->id in the silc_server_free_client_data.
1729 Affected file silcd/server.c.
1731 * Fixed /GETKEY nick@server not to crash if the server entry
1732 is not found. Affected file lib/silcclient/command.c.
1734 * Fixed the silc_server_check_cmode_rights to check the

1740 Affected file silcd/command.c.
1742 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Call the silc_server_udpate_servers_by_server in the
1745 primary router that comes back online in the backup resuming
1746 protocol. Otherwise it routes packets wrong. Affected file
1747 silcd/server_util.[ch], silcd/server_backup.c.
1749 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1752 lib/silcutil/silcbuffmt.[ch].
1754 * Redefined the SILC packet header to include the padding
1755 length. Affected file lib/silccore/silcpacket.[ch].
1757 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1758 length for maximum padding up to 128 bytes). Affected
1759 file lib/silccore/silcpacket.h.
1761 * Removed all backwards support for old 0.5.x MAC thingies.
1762 The SILC packet header change makes it impossible to be
1763 backwards compatible.
1765 * Send the ENDING packet with timeout in the backup resuming
1766 protocol. This is to assure that all routers has connected
1767 to the primary router. Affected file silcd/server_backup.c.
1769 * Changed the RNG to take the first IV from random data. It
1770 used to take it from zero actually. Changed the RNG also
1771 to use /dev/urandom during session. /dev/random is used
1772 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1774 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Changed the SILC packet header to have the first two bytes
1777 (the packet length) encrypted. Affected files aroung the
1778 code tree, lib/silccore/silcpacket.[ch]. Removed the
1779 SilcPacketCheckDecrypt callback. It is not needed anymore
1780 since the silc_packet_receive_process will determine now
1781 whether the packet is normal or special.
1783 * Implemented the unidirectional MAC keys. Affected files
1784 lib/silcske/silcske.c, silcd/protocol.c and
1785 lib/silcclient/protocol.c.

1789 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1790 lib/silcclient/protocol.c.
1792 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Allow backup router to announce servers. All servers
1795 announced by backup router are added to the global list
1796 automatically. Update hte server's socket to our primary
1797 router also when backup router announces a server.
1798 Affected file silcd/packet_receive.c.
1800 * Do not update the client->router in the function
1801 silc_server_udpate_clients_by_server if the client is on
1802 global list. We might fail to find any specific server
1803 for locally connected clients and local cell clients. They
1804 should still use the `from' and not `to' as client->router.
1805 This fixes backup router resuming protocol. Affected file
1806 silcd/server_util.c.
1808 * Decrease channel statistics count only if the channel
1809 deletion worked. Affected files are silcd/server.c and
1810 silcd/server_util.c.
1812 * Added silc_server_update_servers_by_server to update origin
1813 of all server entries. Used during backup router protocol.
1814 Affected files silcd/server_util.[ch], silcd/server.c. and
1815 silcd/backup_router.c.
1817 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1818 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1819 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1820 lib/silccrypt/silchmac.c.
1822 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Assure that router cannot reroute the same channel message
1825 to the sender. Affected file silcd/packet_receive.c.
1827 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Made better checks that the channel message is not sent
1830 to the router it came from. Affected file is
1831 silcd/packet_send.c. Fixed memory leak too.
1833 * Announce informations for incoming router connection, but
1834 only after checking if it is replaced by backup router.
1835 Affected file silcd/packet_receive.c.
1837 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Fixed the backup resuming protocol to work in multiple
1840 router environment. Affected file silcd/server_backup.c.
1842 * Route packet only to one router in the function
1843 silc_server_packet_send_to_channel. Affected file is
1844 silcd/packet_send.c.
1846 * Fixed silc_server_send_notify_dest to set the broadcast
1847 flag. Fixed the silc_server_send_notify_topic to actually
1848 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1849 Affected file silcd/packet_send.c.
1851 * Changed the SFTP Filesystem interface. Changed the
1852 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1853 the filesystem operation function. The SilcSFTPFilesystem
1854 is now a context that is allocated by all filesystem allocation
1855 functions and it already includes the operations structure
1856 and filesystem specific context. It is given as argument
1857 now to the silc_sftp_server_start. This made the interface
1858 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1859 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1861 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Changed the backup router adding and getting interfaces
1864 in the server. The router that will be replaced by the
1865 specified backup router is now sent as argument. Affected
1866 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1869 * Added silc_net_addr2bin_ne to return the binary form of
1870 the IP address in network byte order. Affected files
1871 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1873 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Check for existing server ID in silc_server_new_server
1876 and in silc_server_connect_to_router_final and remove the
1877 old entry if it exists. Affected file silcd/packet_receive.c,
1880 * Send the channel message always to only one router, either
1881 in upstream or downstream. Affected file is
1882 silcd/packet_send.c.
1884 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Wrote the definition of the backup resuming protocol to the
1887 protocol specification.
1889 * Removed one redundant channel key generation from normal
1890 server during joining procedure. Removed one redundant
1891 channel key sending from server to router during joining
1892 procedure. Affected file silcd/command.c.
1894 * Made minor bugfixes to the backup router resuming protocol.
1895 Affected file silcd/server_backup.c, server.c.

1900 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1903 * Implemented the backup resuming protocol that is used to
1904 resume the primary router position in the cell after the
1905 primary router comes back online. Affected files
1906 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1907 and silcd/server_util.[ch].
1909 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Sleep two (2) seconds after sending QUIT command to server.
1912 Affected file lib/silcclient/command.c.
1914 * Assure that if outgoing data buffer is pending do not force
1915 send any data. Affected file silcd/packet_send.c.
1917 * Assure that if outgoing data buffer is pending do not force
1918 send any data. Affected file lib/silcclient/client.c.
1920 * Implemented the backup router support when the primary router
1921 goes down. The servers and routers can now use the backup
1922 router as new primary router without loosing connectivity.
1924 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1927 in the server to indicate disabled entry. All data read
1928 from the connection will be ignored and no data is sent
1929 for entry that is disabled. Affected files are
1930 silcd/idlist.h, silcd/server.c.
1932 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Created SFTP client and server test programs in the
1935 lib/silcsftp/tests directory.
1937 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Implemented memory filesystem (virtual filesystem) for
1940 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1943 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Implemented the SFTP (SSH File Transfer Protocol) to the
1946 lib/silcsftp. It includes SFTP client and SFTP server
1949 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Moved lib/silccore/silcprotocol.[ch] to the
1952 lib/silcutil library.
1954 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1955 take variable argument list pointer as argument. Affected
1956 file lib/silcutil/silcbuffmt.[ch].
1958 * Added silc_buffer_set function that is used to set data
1959 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1960 Affected file lib/silcutil/silcbuffer.h.
1962 * Changed various routines in the core library to use the new
1963 silc_buffer_set instead of allocating new buffer only for
1966 * Added 64-bit value formatting and unformatting support to the
1967 silc_buffer_[un]format routines. Affected file is
1968 lib/silcutil/silcbuffmt.[ch].
1970 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1971 to includes/bitmove.h.
1973 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Fixed channel user mode saving in client library. Affected
1976 file lib/silcclient/command[_reply].c.
1978 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Defined the file transfer to the SILC Protocol. Added
1981 new packet type SILC_PACKET_FTP and defined File Transfer
1982 Payload. The mandatory file transfer protocol is SFTP
1983 (SSH File Transfer Protocol). Affected file in addition
1984 of the internet draft is lib/silccore/silcpacket.h.
1986 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1987 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1988 is used as part of backup router protocol when the primary
1989 router of the cell is back online and wishes to resume
1990 the position as primary router.
1992 * Redefined the MAC generation keys in the protocol. The
1993 same key is not used anymore in both direction. Both
1994 direction will now use different keys for sending and
1995 receiving. This fixes a potential security flaw. This
1996 change causes incompatibilities in the protocol.
1998 * Redefined also the MAC computation from the packet.
1999 An packet sequence number is now added to the MAC
2000 computation. This prevents possible replay attacks against
2001 the protocol. This change too causes incompatibilities
2004 Added `sequence' field to the SilcPacketContext to hold
2005 the current sequence number for the packet.
2007 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Added `created' field to the SilcIDListData in the file
2010 silcd/idlist.h to indicate the time when the entry was
2013 * Added `created' field to the SilcChannelEntry too. Affected
2014 file silcd/idlist.h.
2016 * Added `creation_time' aguments to all the announcement functions
2017 in the server. If it is provided then only the entries that
2018 was created after the provided time frame are actually
2019 announced. Affected file silcd/server.[ch].
2021 * The protocol says that the Channel ID's IP address must be
2022 based on the router's IP address. Added check for this in
2023 the silc_server_new_channel when processing incoming New Channel
2024 Payload. Affected file silcd/packet_receive.c.
2026 * Print out the correct version with --version in SILC client.
2027 Affected file irssi/src/silc/core/silc-core.c.
2029 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Fixed WHOWAS command to check for completnes of the client
2032 entry always, not just when the command is coming from client.
2033 Affected file silcd/command.c.
2035 * Added new function silc_server_packet_queue_purge to purge the
2036 outgoing data queue to the network. After the function returns
2037 it is guaranteed that the outgoing packet queue is empty.
2038 Affected file silcd/packet_send.[ch].
2040 * Purge the outgoing packet queue in the rekey protocol's final
2041 callback to assure that all rekey packets go to the network
2042 before quitting the protocol. Affected file silcd/server.c.
2044 * Added silc_client_packet_queue_parse as similar function as
2045 in server to the client library. The affected file is
2046 lib/silcclient/client.c.
2048 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Splitted silcd/server.c and created silcd/server_util.[ch]
2051 for utility functions.
2053 * Added new socket flag SILC_SF_DISABLED to indicate that the
2054 connection is open but nothing can be sent to or received from
2055 the connection. Affected file lib/silcutil/silsockconn.[ch].
2056 The checking for disabled socket is checked in the low level
2057 silc_socket_write and silc_socket_read functions.
2059 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * Allow only nicknames and channel names that fits into the
2062 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2064 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * When processing JOIN command reply in server check that if
2067 the channel exists in our global list we'll move it the local
2068 list. Affected file silcd/command_reply.c.
2070 * Fixed the check whether client is joined on the channel already
2071 in JOIN command. Affected file lib/silcclient/command.c.
2073 * Fixed the JOIN command reply to check whether the channel
2074 already exists. Affected file lib/silcclient/command_reply.c.
2076 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Added silc_ske_status_string to map the SKE error numbers
2079 to readable strings. The affected files are
2080 lib/silcske/silcske[_status].[ch].
2082 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Do not show the private channels on the WHOIS channel list
2085 as it is not allowed by the protocol. The affected file is
2088 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Assure that the packet length digged from the actual packet
2091 is something sensible in the silc_packet_decrypt_rest_special
2092 in lib/silccrypt/silcpacket.c.
2094 * Free and NULL the allocated pointer in silc_hmac_alloc if
2095 the HMAC allocation fails. The affected file is
2096 lib/silccrypt/silchmac.c.
2098 * Print the selected security properties to the log files in
2099 the server. Affected file silcd/protocol.c.
2101 * Add SKE's reference counter even if calling the completion
2102 callback manually. Otherwise it goes negative, although it
2103 does not cause any problems. The affected file is
2104 lib/silcske/silcske.c.
2106 * Remove the client entry with short timeout after giving the
2107 KILL command. Affected file lib/silcclient/command.c.
2109 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2110 case all found clients are already disconnected (WHOWAS would
2111 found them) in the server. Affected file silcd/command.c.
2113 * Update the last_receive (time of last data received) to be
2114 updated only when received private or channel message so that
2115 the idle time showed in WHOIS makes more sense.
2117 * Added boolean field `valid' in to the SilcClientEntry in the
2118 client library to indicate whether the entry is valid or not.
2119 This fixes the nickname change bug on channel when changing
2120 the nickname to be same than the old (like nick to Nick) the
2121 nickname formatter doesn't set the new nick anymore to Nick@host.
2122 Affected file lib/silcclient/idlist.[ch].
2124 * Now actually fixed the nickname changing on disconnection.
2125 Added new function silc_change_nick to the Irssi SILC Client.
2126 Affected file irssi/src/silc/core/client_ops.c,
2127 irssi/src/silc/core/silc-nicklist.[ch].
2129 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Check that the public key exists in the GETKEY command before
2132 trying to encode it. Affected file silcd/command.c.
2134 * Print some notifications on received public keys with GETKEY
2135 command in the Irssi SILC Client. Affected files are
2136 irssi/src/fe-common/silc/module-formats.[ch],
2137 irssi/src/silc/core/client_ops.c.
2139 * Use IDENTIFY command to resolve the server information in the
2140 GETKEY command instead of INFO command. Affected file
2141 lib/silcclient/command.c.
2143 * All command reply functions in the client library now calls
2144 the pending command reply callbacks even if an error has
2145 occurred. The server has done this a long time and now it was
2146 time to move the client library to this as well. Now all
2147 errors can be delivered back to the pending command reply
2148 callbacks if necessary. Affected files are
2149 lib/silcclient/command[_reply].[ch].
2151 * Change the nickname on disconnection back to the username
2152 because in reconnect the server will enforce it to it anyway.
2153 Affected file irssi/src/silc/core/silc-servers.c.
2155 * Fixed a config file parsing bug in the Irssi SILC client.
2156 Affected file irssi/src/silc/core/clientconfig.c.
2158 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * When printing the channel mode on JOIN, verify that the
2161 channel key and channel's HMAC are valid. Affected file
2162 irssi/src/silc/core/client_ops.c.
2164 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2167 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2168 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2170 * Removed channel key rekey task deleting from the function
2171 silc_server_save_channel_key. Affected file silcd/server.c.
2172 Added explicit timeout task context instead that is used to
2173 delete the task if we are registering a new task before the
2174 new task has elapsed.
2176 * When channel key rekey occurs the client library now saves
2177 the old channel key for a short period of time (10 seconds) and
2178 is able to use it in case some is still sending channel
2179 messages encrypted with the old key after the rekey. Affected
2180 file lib/silcclient/[idlist.h|client_channel.c].
2182 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Added check to the silc_server_new_id_real to not accept
2185 new ID if it is the sender's own ID. Affected file is
2186 silcd/packet_receive.c.
2188 * Assure that we do not announce ourself or the one we've
2189 sending our announcements when we're router and are announcing
2190 servers to our primary router. Affected file silcd/server.c.
2192 * Fixed silc_server_command_identify_check_client to assemble
2193 correct WHOIS packet. It send corrupted WHOIS packet and
2194 caused problem with router to router connections. Affected
2195 file silcd/command.c.
2197 Fixed also silc_server_command_whois_check the same way
2198 as for the IDENTIFY command.
2200 * Added new SilcIDListStatus to the server in the SilcIDListData
2201 structure. The status now includes the current status of
2202 the entry (like registered, resolved etc.). Affected file
2203 silcd/idlist.[ch]. Defined a bunch of different status types
2204 as well. This replaced the old boolean registered field as well.
2206 Added resolve_cmd_ident field to the SilcClientEntry structure
2207 too so that if the entry is for example being resolved so
2208 another command may attach to the same pending command reply
2209 without requiring to resolve the same entry again. This concept
2210 should optimize the WHOIS and the IDENTIFY resolving under
2211 heavy load by taking away unnecessary resolving for entries
2212 that are being resolved already.
2214 Added support for adding multiple pending commands for one
2215 command idenfier. Affected file silcd/command[_reply].[ch].
2217 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2218 before deleting the data. Otherwise the hash table will have
2219 freed data in comparison functions. Affected file is
2220 silcd/command_reply.c.
2222 * Fixed silc_idlist_replace_client_id to add the new entry to
2223 the cache with NULL nickname. Otherwise there will be invalid
2224 memory as the nickname after the nickname is freed. Affected
2225 file silcd/packet_receive.c.
2227 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2228 saved into wrong slots because the previous number of entries
2229 was not taken into account. Affected file silcd/idlist.c.
2230 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2232 * If we are router and we receive JOIN notify to a channel that
2233 does not have any users then notified client is marked as the
2234 channel founder, as it is it. The affected file is
2235 silcd/packet_receive.c
2237 * Added to the extended hash table API's table_del_*ext functions
2238 the destructor as argument too, so that the caller can decide
2239 which destructor to use or whether to use destructor at all.
2240 Affected file lib/silcutil/silchashtable.[ch].
2242 * Fixed ID Cache purging. It actually deleted the entries from
2243 the hash table after the data was freed. The hash table ended
2244 up comparing freed memory. The affected file is
2245 lib/silccore/silcidcache.c.
2247 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2249 * Fixed Irssi SILC client's KILL command's HELP syntax.
2251 * The USERS command now resolves the detailed user information
2252 if the userinfo field is missing. Affected file is
2253 lib/silcclient/command_reply.c.
2255 * Do not print error in silc_file_read if the read file does
2256 not exist. Just silently return NULL. Affected file is
2257 lib/silcutil/silcutil.c.
2259 * Fixed the silc_log_output to not wine about NULL filename
2260 and to not create some bogus " " filename. Affected file is
2261 lib/silcutil/silclog.c.
2263 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Fixed various printing bugs on the user interface in the
2266 Irssi SILC Client. Minor changes that were forgotten from
2269 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Fixed the configure.in.pre and the compilation and distribution
2272 environment to support the new autoconf 2.52. That version is
2273 now required to compile the CVS trunk.
2275 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2278 to generally parse user@fqdn format strings. Affected file
2279 lib/silcutil/silcutil.c.
2281 * Added nickname_format and nickname_force_format fields to the
2282 SilcClientParams structure. The first one defines the format
2283 for the nicknames that the library will enforce if the receives
2284 multiple same nicknames. The second one is boolean value and
2285 can be used to force the library to always enforce the format
2286 to the nicknames regardles whether there are multiple nicknames
2287 or not. This configurable formatting was employed to flexibly
2288 support accessing multiple nicknames from the user interface.
2289 The userinterface can now set the nicknames to what ever format
2290 they prefer. Affected file lib/silcclient/silcapi.h.
2292 Added function silc_client_nickname_format to the file
2293 lib/silcclient/idlist.c. It performs the nickname formatting.
2295 Added new field `hostname´ to the SilcClientEntry context.
2296 It holds the hostname of the client. Affected file is
2297 lib/silcclient/idlist.h.
2299 * Irssi SILC Client sets the nicknames in nick@hostn format.
2300 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2301 irssi/src/silc/core/silc-core.c.
2303 The WHOIS printing now also shows both the real nickname and
2304 the formatted nickname so that user knows how to access the
2305 user if there are multiple same nicknames cached. Affected
2306 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2307 printing formatting too to take the hostname now as a separate
2308 argument. The Affected file is
2309 irssi/src/fe-common/silc/modules-formats.[ch].
2311 * Changed the silc_client_get_clients_local to accept the formatted
2312 nickname as argument. It accepts the real nickname too but the
2313 formatted nickname can be used to find the true entry from
2314 multiple entries. Affected file lib/silcclient/silcapi.h and
2315 lib/silcclient/idlist.c.
2317 * Added nickname_format_parse field to the SilcClientParams.
2318 It is a callback function provided by the application to parse
2319 the nickname out of the formatted nickname string. The library
2320 calls it to get the nickname from the formatted string. Since
2321 the application generally knows better the format of the nickname
2322 string it parses it instead of the library, even though library
2323 encodes the formatted string. If the callback function is not
2324 provided then the library will use the string as is. The
2325 affected file is lib/silcclient/silcapi.h.
2327 * All the nickname strings passed to the client library in
2328 commands are now expected to be formatted nickname strings.
2329 If the command does not support the formatted nickname string
2330 it will assume that the sent string is the actual nickname.
2331 Affected file lib/silcclient/command.c.
2333 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Added public key authentication support to OPER and SILCOPER
2336 commands in the client library. Affected file is
2337 lib/silcclient/command.c.
2339 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Changed the get_auth_methdod client operation to be asynchronous.
2342 It can be async if the application resolves the authentication
2343 method from the server during the negotiation. Added new
2344 SilcGetAuthMeth completion callback that the application will
2345 call after resolving the authentication method.
2347 Added function silc_client_request_authentication_method that
2348 the application can use to resolve the authentication method
2349 from the server. Added also SilcConnectionAuthRequest callback
2350 that the library will call after the server has replied. The
2351 application can call this function if it does not know the
2352 current authentication method.
2354 Affected files are lib/silcclient/client.c and
2355 lib/silcclient/silcapi.h.
2357 * The Irssi SILC client now automatically resolves the authentication
2358 method incase any configuration information is not present (and
2359 currently there never is). The affected file is
2360 irssi/src/silc/core/client_ops.c.
2362 * Fixed public key authentication from the client library.
2363 Affected file lib/silcclient/protocol.c. Changed also the
2364 protocol specification about the public key authentication in
2365 the connection authentication protocol. The actual data to be
2366 signed is now computed with a hash function before signing.
2368 * Fixed the public key authentication from the server as well.
2369 Affected file silcd/protocol.c.
2371 * Removed the mlock()'s from the memory allocation routines.
2372 Affected file lib/silcutil/silcmemory.c. The ./configure does
2373 not check anymore for the mlock(). Affected file is
2376 * Fixed USERS command in server to allow the execution of the
2377 command for private and secret channels if the client sending
2378 the command is on the channel. Affected file silcd/command.c.
2380 * Fixed silc_client_get_clients_local to return the clients
2381 count correctly. It could return wrong value. Affected file
2382 lib/silcclient/idlist.c.
2384 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2387 types. The assembler optimizations seemed not to like 64-bit
2388 data types. The assmebler optimizations thus are now enabled
2389 also for BSD systems as opposed to only enable them for Linux.
2391 * Do not check for threads at all on BSD systems. Affected
2392 file configure.in.pre.
2394 * Removed -n and -h options from the Irssi SILC Client since
2395 they are not used in silc.
2397 * Fixed the prime generation to assure that the first digit
2398 of the generated random number is not zero since our conversion
2399 routines does not like number strings that starts with zero
2400 digit. If zero digit is seen the random number is regenerated.
2401 This caused some corrupted RSA keys when the zero first digit
2402 was met. Affected file lib/silcmath/silcprimegen.c.
2404 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Fixed WIN32 configuration in the ./configure script.
2407 Fixed to include xti.h on environments that has it.
2408 Patches by Carsten Ilchmann and andrew.
2410 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Changed the silc_id_create_client_id to be collision
2413 resistant. It is now assured that there cannot be created
2414 two same client ID's. I suspect that some weird bugs in
2415 the server were actually caused by duplicate Client IDs.
2416 Affected file silcd/serverid.[ch]. A router receiving
2417 new ID now also assures and informs the sending server
2418 if the ID caused collision.
2420 * Changed the silc_id_create_channel_id to also assure that
2421 there are no collisions.
2423 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Statement about ignoring the Mutual Authentication flag when
2426 performing rekey with PFS was a bit misleading. It is ignored
2427 if it was set in the initial negotiation, it cannot be even
2428 set in the rekey. Fixed in the ke-auth draft. Started the
2429 new versions of the protocol drafts in the doc/.
2431 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Fixed a bug in silc_client_command_identify_save when saving
2434 new channel information. The channel name was no duplicated
2435 and caused crash on exit. Affected file is
2436 lib/silcclient/command_reply.c.
2438 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Fixed the getkey command handling in the server. Send just
2441 empty OK reply to the sender if the key could not be fetched
2442 (but everything else was ok, like the key just was not available).
2443 Changed the public key parameter to optional in the protocol
2444 specs so that empty OK reply can be sent. Affected file
2447 Added a message to Irssi SILC client to tell to user if the
2448 server did not return a public key.
2450 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Fixed a channel key regeneration bug. It registered new
2453 timeout tasks exponentially until all system resources were
2454 used. Affected file silcd/server.c.
2456 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Added the SILC Document generator to the scripts/silcdoc.
2459 It can be used to generate the Toolkit Reference Manual out
2460 of the source tree. Internally it will also use the RoboDoc
2461 generator now imported in util/robodoc.
2463 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Added couple of return's in rekey protocol if error orccurred
2466 during the protocol. The execution must be terminated.
2467 Affected file silcd/protocol.c. Also, terminate the protocol
2468 always with timeout.
2470 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * The client's Client ID was created initally from the wrong
2473 nickname (it could have been in format nick@host) in the
2474 silc_server_new_client. Affected file silcd/packet_receive.c
2476 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2478 * Added some SILC_LOG_ERROR's to various error conditions
2479 if client could not be added to ID cache. Affected files
2480 silcd/packet_receive.c and silcd/server.c.
2482 * When client's sock->user_data is freed, NULL also the
2483 client->router and client->connection pointers. Added check
2484 for these pointers being NULL to various places around the
2485 code. Affected file silcd/server.c.
2487 * Added client->data.registered == TRUE checks to various
2488 places around the code to assure that unregistered client's
2489 are not handled when it is not allowed. Affected file
2492 * Added `bool registered' fields to all
2493 silc_idlist_[server|client]_get_* routines to indicate whether
2494 the fetched client needs to be registered or not. Affected
2495 file silcd/idlist.[ch].
2497 * Add your own entry as registered to the ID cache in the
2498 server. Affected file server.c.
2500 * Fixed a bug in silc_server_new_server. The SilcServer was
2501 set as the new server's context instead of SilcServerEntry.
2502 This naturally caused some weird bugs.
2504 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Do not delete the channel rekey task when adding it
2507 for in silc_server_create_channel_key.
2509 * Changed the silc_server_create_channel_key to return
2510 TRUE or FALSE to indicate the success of the channel key
2513 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Fixed MSVC++ project files and added missing files to
2516 Makefiles under win32/.
2518 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Do not add TCP_NODELAY flag if the operating system
2521 does not have it defined. Affected files are
2522 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2524 * Fixed buffer overflow from Irssi SILC Client. Affected
2525 file irssi/src/fe-common/core/themes.c.
2527 * Fixed double free in client library in the file
2528 lib/silcclient/client.c when disconnecting from server.
2530 * Applied double free patch from cras to Irssi SILC client.
2531 Affected files irssi/src/core/[modules/expandos].c
2533 * Fixed the disconnection handling to Irssi SILC Client.
2534 The application must call silc_client_close_connection
2535 in ops->connect client operation in case of failure of
2536 the connection. Affected file is
2537 irssi/src/silc/core/client_ops.c.
2539 * Do not set sock->protocol to NULL in the function
2540 silc_client_close_connection after executing the protocol's
2541 final callback since the sock might not be valid anymore.
2542 Affected file lib/silcclient/client.c.
2544 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Do not enable SILC_THREADS if the linking with libpthread
2547 did not happen. Affected file configure.in.pre.
2549 * Added notion to protocol specification that server must
2550 verify the sent authentication payload with CMODE when
2551 setting the channel founder key. Implemented it to the
2552 server. Affected file silcd/command.c.
2554 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Added _EXTRA_DIST SILC distribution variable to the
2557 distributions file. It is used to conditionally add extra
2558 files or directories to the specific distribution. Affected
2559 files ./prepare, Makefile.am.pre and distributions.
2561 Removed the `_' from the start of the distribution names.
2564 * Added README.WIN32 for instructions to compile the Toolkit
2567 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Fixed a double free in disconnection in the server. Affected
2570 file is silcd/server.c.
2572 * Fixed the lib/silcske/groups.c to work now also with GMP
2573 MP library. The string conversion did not work when using
2574 specific base and the base is indicated in the string as well.
2576 * Created win32/ directory which now includes MSVC++ specific
2577 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2578 It will appear only in the toolkit distribution
2580 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Changed the key material distribution function in case when
2583 the hash output is too short. The data is now concatenated
2584 a bit differently than it used to. Made the change to the
2585 SKE protocol specification.
2587 * Added better GMP detection to configure.in.pre. A patch
2590 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Fixed a minor bug in SKE that might cause some problem on
2593 some platforms. Affected file lib/silcske/silcske.c.
2595 * Added the cookie checking for initiator in the SKE. It checks
2596 that the responder returns the sent cookie unmodified. The
2597 affected file is lib/silcske/silcske.c. Added new SKE
2598 error type INVALID_COOKIE that can be sent during the
2599 negotiation. Fixed some memory leaks as well.
2601 * Added the "invalid cookie" error message to Irssi SILC client's
2604 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Added `task_max' field to the SilcClientParams to indicate
2607 the maximum tasks the scheduler can handle. If set to zero,
2608 default values are used. Affected file lib/silcclient/silcapi.h.
2610 * Fixed memory leaks in silc_client_close_connection. Affected
2611 file lib/silcclient/client.c.
2613 * Added silc_client_del_client_entry to client library to free
2614 all memory of given client entry. Affected file is
2615 lib/silcclient/idlist.[ch].
2617 * Added new functions silc_client_del_channel and
2618 silc_client_del_server to delete channel and server entries.
2619 Affected file lib/silcclient/[silcapi.h/idlist.c].
2621 * Removed silc_client_del_client_by_id from silcapi.h.
2623 * Fixed the INFO command to return the server's own info
2624 correctly when querying by Server ID. Affected file is
2627 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Removed the non-blocking settings in WIN32 code in the
2630 silc_sock_[read/write] and added SleepEx instead. Affected
2631 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2632 of input data is now checked with FIONREAD and ioctlsocket.
2634 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * Call silc_schedule_task_del_by_context in the
2637 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2638 Affected file lib/silccore/silcprotocol.c.
2640 * Call silc_protocol_cancel for active protocols in the
2641 silc_server_close_connection if the funtion
2642 silc_server_free_sock_user_data has not been called.
2643 Affected file silcd/server.c.
2645 * Generic tasks cannot be deleted using the del_by_fd
2646 task deleting function since generic tasks does not match
2647 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2649 * Added a notion to SILCOPER help file that the SILCOPER works
2650 only on router server, not on normal server.
2652 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Added for WIN32 support for the new scheduler as well.
2655 Affected file lib/silcutil/win32/silcwin32schedule.c.
2657 * Fixed the SHA1 implementation to work on various platforms.
2659 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2662 API. It is part of the scheduler now. Everything else is
2663 as previously but some functions has changed their names.
2664 Checkout the lib/silcutil/silcschedule.h for the interface.
2665 Updated all applications to use the new interface. Affected
2666 files are lib/silcutil/silcschedule.[ch].
2668 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Found a bug in the SKE implementation. The HASH value,
2671 specified by the protocol, was not computed correctly. The
2672 public key of the responder was not added to the computation
2673 even though it is mandatory. Affected file lib/silcske/silcske.c.
2674 This unfortunately causes incompatibilities with older
2675 clients and servers.
2677 * Added WIN32 specific network init and uninit functions:
2678 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2679 the Winsock2. Affected file lib/silcutil/silcnet.h and
2680 lib/silcutil/win32/silcwin32net.c.
2682 * Set the socket always to nonblocking mode on WIN32 after
2683 reading data or writing data. Affected file is
2684 lib/silcutil/win32/silcwin32sockconn.c.
2686 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Fixed various compilation problems under WIN32. Affected
2689 files lib/silcutil/win32/silcwin32thread.c and
2690 lib/silcutil/win32/silcwin32schedule.c.
2692 * Removed all _internal.h #includes from public header
2693 files. Internal headers must never be included from
2696 Removed also the lib/silcske/payload_internal.h file.
2698 * All include files that may be needed (public and some others
2699 included by the public headers) by application developers are
2700 now copied to the ./includes directory. It does not copy any
2701 internal headers. Affected file Makefile.defines.pre and all
2702 Makefile.am's under lib/ and subdirs.
2704 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2706 * Do not change the ~/.silc directory's permissions automatically.
2707 Affected file irssi/src/silc/core/clientutil.c.
2709 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Do not cancel the protocol in silc_server_close_connection
2712 it might cause recursion. Now cancelled in the function
2713 silc_server_free_sock_user_data. Affected file silcd/server.c.
2715 * Fixed the silc_server_remove_clients_by_server to regenerate
2716 the channel keys correctly finally. Added also new function
2717 silc_server_remove_clients_channels to actually do it.
2718 Affected file silcd/server.c.
2720 * Fixed the silc_server_new_channel to not crash by giving
2721 wrong router to the new channel. Affected file is
2722 silcd/packet_receive.c.
2724 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2727 which is given as argument to the silc_client_alloc now.
2728 It can be used to configure the client and set various parameters
2729 that affect the function of the client.
2731 * The USERS command in server did not check whether the channel
2732 is private or secret. Affected file silcd/command.c.
2734 * Added new argument to the USERS command in protocol specification.
2735 The USERS command now can take the channel name as argument
2736 as well. Added support for this in client and server and
2737 updated the protocol specs.
2739 * Completed the GETKEY command in client. It can be now used
2740 to fetch also servers public key not only some clients.
2741 Affected files lib/silcclient/command[_reply].c.
2743 * Added silc_client_get_server to return server entry by the
2744 server name. Affected files lib/silcclient/silcapi.h and
2747 * Redefined the IDENTIFY command in protocol specification to be
2748 more generic. It now can be used to query information about
2749 any entity in the SILC Network, including clients, servers and
2750 channels. The query may be based either the entity's name
2751 or the ID. Added support for this in both client and server.
2753 Affected files silcd/command.c and lib/silcclient/command.c
2754 and command_reply.c.
2756 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2757 the _from_client and _from_server functions. Affected file
2760 * Added silc_client_get_channel_by_id_resolve to the file
2761 lib/silcclient/silcapi.h to resolve channel information by
2762 its ID. Added also silc_client_get_channel_by_id that
2763 does not resolve it from the server.
2765 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Added SilcServerEntry context into the client library
2768 to represent one server. The INFO command now allocates
2769 these to save the resolved server info. For now on the
2770 client library will also keep information about servers,
2771 connected and resolved with INFO.
2773 The INFO command now allocates the SilcServerEntry context
2774 and saves the server info there. The COMMAND_REPLY in
2775 the INFO now returns the parameters to application in
2776 same order as defined in the protocol specification.
2778 The entries are cached in the client->server_cache.
2780 * The INFO command is now issued after received the Client ID
2781 from the server. Affected file lib/silcclient/client.c.
2783 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2784 to the application as the mode changer might be server.
2785 It is guaranteed that NULL is not returned anymore to the
2786 application. Affected file lib/silcclient/client_notify.c.
2788 The ID Type is now also passed to the application so that
2789 it can check whether the returned entry is SilcClientEntry
2792 Added new function silc_client_get_server_by_id to return
2793 the server entry by ID. Affected files are the
2794 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2796 * Do not create the channel in the Irssi SILC Client when issuing
2797 the JOIN command but when received the sucessful JOIN command
2798 reply. Otherwise the channel might get created even though we
2799 could not join it. The Affected file is
2800 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2802 * Fixed a channel joining bug in router. The router must also
2803 check the channel modes, invite and ban lists etc. when serving
2804 the JOIN command sent by normal server. Affected file is
2805 silcd/command.c. The router now resolves the client's
2806 information from the server who sent the JOIN command if it
2807 does not know it, and processes the JOIN command only after
2810 * Changed the SilcCommandCb to take new argument; void *context2.
2811 Affected file lib/silccore/silccommand.h
2813 The second argument in the command callbacks in the server now
2814 includes the SilcServerCommandReplyContext if the command was
2815 called as pending command callback from the command reply.
2816 Otherwise it is NULL. When called as pending the status of the
2817 command reply will be checked and if it was erronous the
2818 error will be sent to the original sender of the command.
2819 This way the client always receives the error messages even
2820 though the server was actually the one who received the error
2821 when it resent the command to router, for example. Affected
2822 files silcd/command[_reply].[ch].
2824 * Fixed sending WHOWAS command's error message to client if
2825 the requested client could not be found. It was missing.
2828 * Changed the CMODE and CUMODE commands reply arguments in the
2829 protocol specification. The Channel ID is now sent in both
2830 of the commands to identify the channel. Implemented this
2831 new feature to the client and server. Affected files
2832 lib/silcclient/command_reply.c and silcd/command.c.
2834 * Made better checks for invite and ban lists in the JOIN
2835 command in server. Affected file silcd/command.c.
2837 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * The server now performs the incoming host IP/DNS lookup
2840 using the silc_socket_host_lookup and thus does not block
2841 the server anymore. Affected file silcd/server.c.
2843 * Completed the multi-thread support for SILC Scheduler in
2844 the lib/silcutil/silcschedule.c.
2846 * Fixed the configure.in.pre to detect the pthread correctly
2849 * Fixed a deadlock in silc_task_queue_wakeup in the file
2850 lib/silcutil/silctask.c.
2852 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Added new function silc_schedule_wakeup that is used in
2855 multi-threaded environment to wakeup the main thread's
2856 schduler. It needs to be used when a thread adds a new task
2857 or removes a task from task queues. After waking up, the
2858 scheduler will detect the task queue changes. If threads
2859 support is not compiled in this function has no effect.
2860 Implemented the wakeup mechanism to both Unix and WIN32
2861 systems. Affected files are lib/silcutil/silcschedule.[ch],
2862 lib/silcutil/unix/silcunixschedule.c and the
2863 lib/silcutil/win32/silcwin32schedule.c.
2865 * Added new function silc_task_queue_wakeup to wakeup the
2866 scheduler by the specified task queue. Affected file
2867 lib/silcutil/silctask.[ch].
2869 * The silc_socket_host_lookup_start now wakes up the scheduler
2870 after adding the timeout task. Affected file is
2871 lib/silcutil/silcsockconn.c.
2873 * The silc_socket_host_lookup is synchronous now if the threads
2874 support is not compiled in. However, the callback is still
2875 called asyncronously through the scheduler, anyway. Affected
2876 file lib/silcutil/silcsockconn.c.
2878 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Added new function silc_socket_host_lookup to perform
2881 asynchronous IP and FQDN lookups for the socket connection.
2882 Affected files lib/silcutil/silcsockconn.[ch].
2884 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2887 that may or may not compile the mutex support in.
2889 Changed the silc_mutex_alloc interface. It allocates the
2890 mutex now to the sent pointer and returns TRUE or FALSE.
2892 Affected file lib/silcutil/silcmutex.h.
2894 * Wrote the SILC Task Queue interface to support multi-threads.
2895 Affected file lib/silcutil/silctask.[ch].
2897 * Wrote the SILC Scheduler to support multi-threads. Affected
2898 file lib/silcutil/silcschedule.c.
2900 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2903 in lib/silcutil/win32/.
2905 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Defined SILC Mutex API and SILC Thread API and implemented
2908 them for Unix. Affected files are
2909 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2910 lib/silcutil/unix/silcunixmutex.c and
2911 lib/silcutil/unix/silcunixthread.c.
2913 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Fixed the silc_server_remove_clients_by_server's channel
2916 key re-generation. The hash table handling was incorrect
2917 and would not work with many channels. Affected file is
2920 * Fixed some memory leaks around the server code.
2922 * Rewrote the silc_server_get_users_on_channel to support IPv6
2923 based Client ID's. Affected file silcd/server.c.
2925 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2926 specification. However, a separate document must be written
2927 to define the detailed signing procedure and the payload
2928 associated with the flag. Defined the flag to the
2929 lib/silccore/silcchannel.h as well.
2931 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Changed the dynamic tables to static size tables in the
2934 lib/silccrypt/silchmac.c.
2936 * Removed GCC dependencies from the code. A patch by cras.
2938 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * Do not show the error "Error receiving packet bla bla"
2941 in server if it really was not an error (-2 means that reading
2942 is pending). Affected file silcd/server.c.
2944 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Fixed a possible crash in silc_server_remove_clients_by_server
2947 in silcd/server.c. Fixed there also some memory leaks.
2949 * Fixed the silc_idlist_replace_client_id. It could replace
2950 wrong key in the hash table. Affected file silcd/idlist.c.
2952 * Do not check whether there are global users on the channel
2953 if the channel->global_users is FALSE. Affected functions
2954 silc_server_remove_from_one_channel and
2955 silc_server_remove_from_channels in silcd/server.c. Also,
2956 do not check if the removed client is local as we can be
2957 sure that global client was not removed from the channel
2958 and checking for global users is not needed.
2960 * The silc_server_remove_clients_by_server now re-generates
2961 the channel keys correctly for those channels that had
2962 clients removed from them. Affected file silcd/server.c.
2964 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Found the reason of random crashes in the server. We weren't
2967 ignoring the SIGPIPE signal (which can be sent in write())
2968 and it crashed the server. Affected file silcd/silcd.c.
2970 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Assure that sock->user_data is not NULL in the function
2973 silc_server_packet_send in silcd/packet_send.c.
2975 * Disconnect the remote connection if it could not be added
2976 to any ID lists in the server. The affected file is
2979 * Check in silc_server_packet_send[_real/dest] that the
2980 socket is not disconnecting and ignore the data if it is.
2981 Affected file silcd/packet_send.c.
2983 * Define inline to __inline on native WIN32 compilation.
2984 Affected file includes/silcwin32.h.
2986 * Added some explicit type casts for inline code since MSVC
2987 require them. Affected files lib/silcutil/silcbuffer.h,
2988 lib/trq/silcdlist.h and lib/trq/silclist.h.
2990 * Print warning in log files from now on if the packet
2991 decryption fails. Affected file silcd/server.c.
2993 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Changed the `say' client operation's interface to accept
2996 new `type' argument to indicate the type of the message sent
2997 by the library. The application may filter the library's
2998 messages according the type. The affected file is the
2999 lib/silcclient/silcapi.h.
3001 * Added two new functions to lib/silcclient/silcapi.h:
3002 silc_client_del_client and silc_client_del_client_by_id.
3003 Affected file lib/silcclient/idlist.c.
3005 * Moved the clientincludes.h from includes/ to silc/ and
3006 serverincludes.h from includes/ to silcd/.
3008 * The modes for the CMODE and CUMODE are now passed as
3009 uint32 for application with COMMAND_REPLY. The affected
3010 file is lib/silcclient/command_reply.c.
3012 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * /WHOIS without arguments shows client's own information.
3015 Affected file lib/silcclient/command.c.
3017 * Changed PING to not accept any arguments. The specs
3018 says that client can ping only the connected server so
3019 requiring an argument is not needed. Affected file is
3020 lib/silcclient/command.c.
3022 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * Fixed a fatal bug in private message sending and reception
3025 encryption and decryption when using private message keys.
3026 The implementation was incorrect and did not follow the
3027 specification. It causd that some of the message were
3028 lost since it did not use the sending and receiving keys
3029 as the protocol suggests. This has been fixed and will cause
3030 incompatibilities with older clients when sending private
3031 message encrypted with private message keys. Affected files
3032 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3033 and various other in Irssi SILC Client.
3035 Added `responder' boolean argument to the functions
3036 silc_client_add_private_message_key[_ske] to indicate when
3037 the key is added as responder or initiator of the key
3040 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Removed the silc_ske_check_version function and created
3043 a SilcSKECheckVersion callback. Added also a function
3044 silc_ske_set_callbacks that is now used to set all SKE
3045 callbacks. The callback functions are not given to
3046 the SKE functions anymore, but this function is used to
3049 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3051 * Added `silc_version' argument to the silc_client_alloc
3052 to define the version of the application for the library.
3053 The library will use the version string to compare it
3054 against the remote host's (usually a server) version
3055 string. Affected file lib/silcclient/silcapi.h
3057 * Added the KE protocol context to Key Agreement context
3058 in client library so that we can abort the SKE if it
3059 is in process when we get timeout. Affected file is
3060 lib/silcclient/client_keyagr.c.
3062 * Do not resolve the client ID forever if it returns in the
3063 first time that such client does not exist. This was done
3064 for example with private message. Affected file is
3065 lib/silcclient/client_prvmsg.c.
3067 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Do not add regex.h for WIN32. The affected file
3070 includes/silcincludes.h.
3072 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3073 not work yet 100%. It generates the DLL's automatically
3074 when compiling with --with-win32 under cygwin.
3076 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * lib/contrib/regex.c is not compiled on WIN32.
3080 * Added silc_net_get_socket_opt function to the
3081 lib/silcutil/silcnet.h.
3083 * Added includes/silcwin32.h for WIN32 specific includes
3086 * Do not use ptime structure or any of the posix process
3087 functions on WIN32 in lib/silccrypt/silrng.c.
3089 * Added silc_gettimeofday to provide generic function
3090 for struct timeval on all platforms. Added the function
3091 to lib/silcutil/silcutil.h.
3093 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3096 library as they clearly belong there. As a plus side we
3097 can make the actual socket connection routines platform
3100 Added also new generic function silc_socket_read and
3101 silc_socket_write (that used to be silc_packet_[read/write].
3102 The implementation of these are platform specific.
3104 * Added WIN32 specific routines of silc_socket_[read/write]
3105 to lib/silcutil/win32/silcwin32sockconn.c.
3107 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Added preliminary support for native WIN32 compilation under
3110 cygwin (using the -mno-cygwin option for GCC) to the
3111 ./configure.in.pre. The --with-win32 now prepares the
3112 compilation for native WIN32.
3114 * Rewrote the SILC Scheduler interface in the file
3115 lib/silcutil/silcschedule.h. The scheduler is now context
3116 based and does not have anymore any global static scheduler.
3117 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3118 and created lib/silcutil/win32 directory for WIN32 based
3121 * Added Unix specific network routines to the
3122 lib/silcutil/unix/silcunixnet.c and the old
3123 lib/silcutil/silcnet.c includes now only generic routines.
3125 Added WIN32 specific network routines to the
3126 lib/silcutil/win32/silcwin32net.c.
3128 * Added Unix specific utility functions from the
3129 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3131 * Added WIN32 SILC Scheduler to the file
3132 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3135 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3137 * Do not handle JOIN notify in the server if the target client
3138 is not registered (idata->registered == FALSE). The affected
3139 file is silcd/packet_receive.c.
3141 * Update the nickrec->founder in event_cumode in the Irssi SILC
3142 client. Affected file irssi/src/silc/core/silc-channels.c.
3144 * Fixed the CUMODE_CHANGE notify handling in the server when
3145 server and router are announcing their clients on channels.
3146 Now the mode changes are saved and notified correctly. The
3147 affected file is /silcd/packet_receive.c.
3149 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3150 They really did not replace the cache entry in the ID Cache.
3151 Now they do that. Affected file silcd/idlist.c.
3153 * Fixed the KICK notify handling in the Irssi SILC client to
3154 update the channel records so that the kicked client does not
3155 appear to be on the channel. The affected file is
3156 irssi/src/silc/core/silc-channels.c.
3158 * Always update the conn->current_channel when executing command
3159 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3161 * Fixed the KILL notify handling in Irssi SILC client to remove
3162 the killed client on all channels.
3164 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Fixed the silc_parse_command_line to remove extra spaces
3167 from the start and end of the arguments. Affected file is
3168 lib/silcutil/silcutil.c.
3170 * Cancel and free any active protocol in the function
3171 silc_server_close_connection. Affected file silcd/server.c.
3173 * Cancel and free any active protocol in the function
3174 silc_client_close_connction. Affected file is
3175 lib/silcclient/client.c.
3177 * Do not execute the KILL command for clients that are in
3178 history (ie. they are not in the network). Affected file is
3181 * Fixed KILL notify handling, client does not crash anymore.
3182 Affected file irssi/src/silc/core/silc-channels.c.
3184 * Reduced the default packet buffer size from 2048 to 1024 in
3185 lib/silccore/silcpacket.c.
3187 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3188 counter to the SKE context that is incresed when the SKE library
3189 performs async operation outside the library. If the outside
3190 process frees the SKE context and FREED status will be set
3191 and the library will detect after the sync operation that the
3192 libary is freed. The affected files are
3193 lib/silcske/silcske[_status].[ch].
3195 * Resolve the client entry information in the function
3196 silc_client_channel_message to assure that NULL pointer is not
3197 passed as client entry to the application. */
3199 * Fixed the task timeout calculation to assure that there is
3200 never negative timeouts. The affected file is
3201 lib/silcutil/silcschedule.c.
3203 * Fixed the channel user mode notification sending in server.
3204 It was sent point-to-point to the router (or to server by router)
3205 but it needs to be destined to a channel. The routines now
3206 supports sending the channel user mode notifys to the channels
3207 when announcing clients and channels. Affected files are
3208 silcd/server.c and silcd/packet_receive.c.
3210 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3211 It did not actually replace the old channel entry in the cache.
3212 Affected file lib/silcclient/client_notify.c.
3214 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Fixed a possible crash in silc_packet_send_prepare. It now
3217 assures always that there is enough space in the buffer and
3218 at the tail area of the buffer (for MAC).
3220 Fixed the inbound buffer reallocation in silc_packet_read.
3221 It was old code and did not handle the reallocation correctly.
3224 The affected file is lib/silccore/silcpacket.c.
3226 * Fixed buffer overflow in silc_parse_nickname in the file
3227 lib/silcutil/silcutil.c.
3229 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * make install generates new server keys only if there is not
3234 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3237 Added check that if the NOREPLY is set then we will not send
3238 the away message. This avoids infinite loop of away messages
3239 if both clients are away. The affected file is
3240 lib/silcclient/client_prvmsg.c.
3242 * Fixed client crash if /NICK was given without arguments.
3243 Affected file lib/silcclient/command.c.
3245 * Server does not send the invite list in INVITE command back
3246 to the client if the list was not altered. Added this notion
3247 to the protocol spec as well. Affected file silcd/command.c.
3249 Fixed possible crash in INVITE command by checking the
3250 value of silc_server_get_client_route command.
3252 * Fixed the INVITE notify type handling. The arguments are now
3253 taken in correct order and client does not crash. The affected
3254 file is irssi/src/silc/core/silc-channels.c.
3256 Removed the "Inviting xxx to channel" message from the
3257 client library away and let the application handle it.
3258 Affected file lib/silcclient/command.c. Added that message
3259 to Irssi SILC client's message formats.
3261 * Fixed CMODE command crash in client. It now checks the
3262 amount of arguments correctly and does not crash. The affected
3263 file is lib/silcclient/command.c.
3265 * Do not create new channel automatically in silc_channels_join
3266 but check whether the channel by that name already exists.
3267 Affected file irssi/silc/core/silc-channels.c.
3269 * Do not send the SERVER_SIGNOFF to router if the disconnected
3270 entity was the router. Affected file silcd/server.c.
3272 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3273 SILC client as it was missing from there.
3275 Added the handling of the KICK notify to the Irssi SILC client
3276 as it was missing. Added "you have been kicked" message to
3277 Irssi SILC client's message modules formats.
3279 Added the handing of the KILL notify to the Irssi SILC client
3280 as it was missing. Added the kill message module formats
3283 The affected file is irssi/src/silc/core/silc-channels.c.
3285 * The router did not save the channel mode the server announced.
3286 Affected file silcd/packet_receive.c.
3288 * Fixed a possible crash in INFO command in server. If the
3289 server did not provide the server info it crashed. Affected
3290 file silcd/command.c.
3292 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Fixed the GETKEY command in the server to check also the
3295 global list. Otherwise the GETKEY would not work correctly
3296 in normal SILC server. Affected file silcd/command.c.
3298 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Fixed GETKEY crash, it crashed if the command did not succseed.
3302 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3305 is now real and not just an macro interface to GMP.
3307 Removed the entire GMP from the source tree and imported new
3308 NSS MPI library instead. Reason for removing GMP is that it is
3309 extremely large and compiles extremely slow. The NSS MPI
3310 is only a few files and compiles in less than 10 seconds.
3311 The speed is also about the same as GMP. The MPI is imported
3312 to lib/silcmath/mpi.
3314 If the system has GMP installed we will still use the GMP.
3315 If it is not then the NSS MPI will be compiled.
3317 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Merged a long nickname (127 characters long) crash bugfix from
3320 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3322 * Merged a freed memory reference bugfix from Irssi CVS tree.
3323 Affected file irssi/src/core/commands.c.
3325 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Added the server's public key sving and verification to the
3328 server when performing the SKE. This was missing and the
3329 remote server's (or router's) public key was accepted without
3330 checking whether we have it previously or trust it at all.
3331 Affected file silcd/protocol.c.
3333 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Check in the silc_server_timeout_remote if protocol is active
3336 and make sure that the protocol's final callback is called so
3337 that all memory if freed. Affected file silcd/server.c.
3339 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * silc_server_whois_send_reply crashed the server if the nickname
3342 was 127 characters long. Affected file silcd/command.c.
3344 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Added sanity check to the silc_server_new_client. If the hostname
3347 is provided inside username then check that the provided hostname
3348 really is the same as the resolved one. If the hostname was not
3349 resolved then check it from the public key. Affected file is
3350 silcd/packet_receive.c.
3352 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3353 if the server disconnected us and the connection is not valid
3354 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3356 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3357 the library to the lib/silcutil/silcutil.[ch].
3359 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Close log file after open. Affected file
3362 lib/silcutil/silclog.c.
3364 * Check whether sock == NULL in silc_client_send_packet and return
3365 if it is. Affected file lib/silcclient/silcclient.c.
3367 * Check rec->entry == NULL in the Irssi SILC Client before
3368 sending the channel message. Affecte file is
3369 irssi/src/silc/core/silc-servers.c.
3371 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Merged a splitted window bugfix from Irssi CVS tree. The
3374 affected file is irssi/src/fe-text/textbuffer-view.c.
3376 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3377 It did not print nickname.
3379 * Improved the distributions system a bit.
3381 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3384 irssi/src/fe-text/gui-window.c.
3386 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3387 to in-active server. The affected file is
3388 irssi/src/silc/core/client_ops.c.
3390 * Resolve the client in USERS command reply if the entry does
3391 not have username resolved. The affected file is
3392 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3393 command to WHOIS command to really resolve stuff. The USERS
3394 is not used any more in any critical section so WHOIS can
3395 be used even though it might be slower than IDENTIFY.
3397 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3400 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Changed the protocol API a bit more consistent in the
3403 lib/silccore/silcprotocol.[ch].
3405 * Changed the following headers to ROBODoc format:
3407 lib/silccore/silcpayload.h
3408 lib/silccore/silcprotocol.h
3409 lib/silccore/silcsockconn.h
3411 All core library headers are now formatted.
3413 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Fixed a bug in Irssi SILC client; do not show that you are
3416 server/router operator if you really are not. Affected file is
3417 irssi/src/silc/core/client_ops.c.
3419 * Renamed silc_command_free_payload to silc_command_payload_free.
3420 Affected file lib/silccore/silccommand.h
3422 * Added silcmath.h to include the prototoypes of various routines
3423 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3426 * Changed the following headers to ROBODoc format:
3428 lib/silccore/silcchannel.h
3429 lib/silccore/silccommand.h
3430 lib/silccore/silcid.h
3431 lib/silccore/silcidcache.h
3432 lib/silccore/silcmode.h
3433 lib/silccore/silcnotify.h
3434 lib/silccore/silcpacket.h
3435 lib/silcmath/silcmath.h
3437 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Added checking to the server code not to start the server if
3440 ciphers and stuff are not configured properly. Affected files
3441 silcd/serverconfig.[h] and silcd/server.c.
3443 * Changed the layout of the header files of the public interfaces
3444 in the SILC libraries. The new layout supports ROBODoc
3445 documentation tool (and some others) so that it is easy to create
3446 a library reference manual. All the other headers and source
3447 code must still follow the CodingStyle document. Also source
3448 code must not include these ROBODoc stuffs, only the headers.
3449 Furthermore, all public interface headers must now be named
3450 by using `silc' prefix, example: silcapi.h, silccipher.h.
3451 Some files were renamed due to this. All the other headers
3452 must not be used as public interfaces. I will update the
3453 CodingStyle document later. Changed following headers, so far:
3455 lib/silcclient/silcapi.h
3456 lib/silccore/silcauth.h
3457 lib/silccore/silcprivate.h
3458 lib/silccrypt/silcdh.h
3460 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Removed silc_client_packet_send_flush from the client library
3465 as it is not needed. Affected file lib/silcclient/client.[ch].
3467 * Added printing of message of unresolved authentication method
3468 to the Irssi SILC client. Added it to the module formats.
3469 Removed the same message from the client library.
3471 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Added new distribution feature, DISTLABEL. Every distribution
3474 can define own preprocessor label that can be used in the
3475 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3476 file distributions, acconfig.h.pre and prepare.
3478 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Added Makefile.defines_int to include the actual definitions
3481 for Makefile.defines.in. Tested the new distribution system,
3482 created distributions and tested installation.
3484 * Added AWAY message printing to the Irssi SILC client. Added
3485 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3487 * Added SCONNECT command to call the SILC's CONNECT command.
3488 Cannot use CONNECT directly since Irssi uses that internally.
3489 Affected file irssi/src/silc/core/silc-servers.c.
3491 Added ACTION local command. It is same as ME command but takes
3492 the channel as mandatory argument.
3494 Rewrote some of the Irssi's help files to suite for SILC
3497 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Added Makefile.defines[.in] that should for now on be included
3500 in all Makefile.am file in the source tree. That file includes
3501 all common compilation definitions for SILC source tree.
3503 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Minor changes to the ./prepare script to change the package
3506 name according the distribution name to the configure.in.
3508 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Created new distribution system. Added file `distributions'
3511 that defines all the distributions that can be created out of
3512 the SILC source tree. The ./prepare script now reads that
3513 file to determine how to prepare the distributions. The
3514 first argument to the ./prepare is the name of the distribution
3515 and second is the version of the distribution. If given
3516 without arguments it creates the default (toolkit) distribution
3517 with the default version (defined in ./prepare).
3519 All Makefile.am files that are subject to the distributions
3520 are now named as Makefile.am.pre. These are ./Makefile.am
3521 and lib/Makefile.am. Others may be changed later.
3523 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Added invite list, ban list, some key management and connection
3526 error message printing to module formats in the Irssi SILC client.
3528 * Added new silc_client_set_away_message to set the away message
3529 that is back to the person who sent private message. The
3530 affected file lib/silcclient/silcapi.h and the
3531 lib/silcclient/client_prvmsg.c.
3533 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Fixed the private message sending in the Irssi SILC client,
3536 added local command KEY to the Irssi SILC client.
3538 Added key management and key agreement message formats to the
3539 irssi/src/fe-common/silc/module-formats.[ch].
3541 Added USERS (alias WHO) printing, server/router operator
3542 indication and LIST command printing to the module formats.
3544 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Fixed channel joining notify handling, cumode notify handling
3547 from Irssi SILC client.
3549 * Added SILC specific module-formats to the Irssi SILC client so
3550 that SILC specific message hilighting, colors etc is possible.
3551 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3553 Added channel mode, channel user mode, actions, notices,
3554 whois and whowas printing to the the module-formats.c.
3556 * Fixed a bug in channel deletion in the server. The channel
3557 is not left to the cache even if the channel founder auth mode
3558 is set when there are no users anymore on the channel. Affected
3559 file silcd/server.c.
3561 * The silc_net_localhost now resolves the entire hostname including
3562 the domain name. Affected file lib/silcutil/silcnet.c.
3564 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Changed the ask_passphrase client operation to be ascynchronous.
3567 It has now a completion callback and a context that the
3568 application must call after it has got the passphrase from
3569 the user. Affected files lib/silcclient/silcapi.h,
3570 lib/silcclient/protocol.c, lib/silcclient/command.c and
3573 Added SilcAskPassphrase callback that the application calls
3574 to deliver the passphrase to the library.
3576 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3577 The public key verification and especially a certificate
3578 verification is asynchronous procedure.
3580 Added new SILC_SKE_STATUS_PENDING status to indicate the
3581 request is pending and a callback will be called to finalize
3584 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3585 indicate that remote end did not send its public key (or
3586 certificate), even though we require it. Added check for this
3587 condition in the SKE. This was a security bug, now fixed.
3589 Defined new SilcSKEVerifyCbCompletion callback that is called
3590 when the verification process is completed.
3592 The affected files lib/silcske/silcske_status.h and
3593 lib/silcske/silcske.[ch].
3595 * Changed the verify_public_key client operation to be async
3596 as well. Defined SilcVerifyPublicKey callback that is used to
3597 indicate the success of the public key verification process.
3599 Changed the server and client to use the new async client
3602 * Changed the Irssi SILC client's internal scheduler to be called
3603 twice as many times as it used to be. As a result the client
3604 should be a bit faster now. Affected file is
3605 irssi/src/silc/core/silc-core.c.
3607 * Added support to Irssi SILC client of asynchronous public key
3608 verification and passphrase inquiry. Affected file is
3609 irssi/src/silc/core/silc-core.c.
3611 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Do not say "You have left channel %s" in client library.
3614 Moved it to the application. Affected files are
3615 lib/silcclient/command.c and silc/client_ops.c.
3617 * Fixed silc_client_get_clients. Command context was not
3618 duplicated and was freed memory in the callback. Affected
3619 file lib/silcclient/idlist.c.
3621 * Do not say "you are now talking..." on JOIN command in the
3622 client library. The appliation must handle it.
3624 * Do not say ".. changed topic to" in command reply in the
3625 client libary. The application must handle it.
3627 * Fixed TOPIC command sending in the client library.
3629 * Fixed a memory leak in silc_client_command_free in the file
3630 lib/silcclient/command.c.
3632 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Imported a modified version of Irssi client to the source tree.
3635 The Irssi will be used to create a new client called
3636 Irssi SILC. Imported to irssi/.
3638 Added silc_core_init_finish function to the Irssi. Affected
3639 file irssi/configure.in.
3641 A lot changes in the Makefile.ams around the irssi tree.
3643 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Do not rehash if the new size is same as the old size of the
3646 hash table, in the silc_hash_table_rehash*. The affected file
3647 lib/silcutil/silchashtable.c.
3649 * Replaced hash_table_del_by_context calls from the server
3650 (when channel->user_list and client->channels) to the
3651 hash_table_del as it is sufficient and faster.
3653 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Added silc_hash_table_list, silc_hash_table_get and the
3656 SilcHashTableList structure to provide an alternative way to
3657 traverse the hash table. The affected files are
3658 lib/silcutil/silchashtable.[ch].
3660 * Changed the server's idlist routines to use the hash table
3661 routines to optimize the code.
3663 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Replaced the client entry's `channel' list and channel entry's
3666 `user_list' list to hash tables for optimized lookup. Changed
3667 the code to use the hash table interface around the code.
3668 Affected file lib/silcd/idlist.[ch].
3670 * Added `auto_rehash' boolean argument to the function
3671 silc_hash_table_alloc to indicate whether the hash table should
3672 auto-rehash when it thinks is appropriate time. It will
3673 increase the hash table size if the there is twice as much
3674 entries in the table than the size of the table, and will
3675 decrease the size if there are twice as less entries than
3676 the size of the table.
3678 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3682 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * silc_idcache_purge_by_context deletes the entry now by context
3685 as it is supposed to do. Affected file lib/silccore/idcache.c.
3687 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3688 client is not anymore valid (WHOWAS givens the info) and not
3689 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3691 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Removed the `data' and `data_len' arguments from the ID Cache
3694 interfaces and added `name' argument. ID Cache does not handle
3695 anymore the binary data only a names associated with given ID.
3697 * When hashing a Client ID with silc_hash_id the entire ID is
3698 not hashed anymore, instead only the hash of the Client ID is
3699 hashed. This way we can access the Client ID from the cache
3700 with Client ID but with the hash of the ID (which is a hash of
3701 the nickname) as well without any difference in performance.
3703 Added also silc_idcache_find_by_id_one_ext to do one on one
3704 searching when we have the actual ID. Added also function
3705 silc_hash_client_id_compare. The affected files are
3706 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3708 * When hashing the name associated with a ID it is always done
3709 in lowercase. This way we can access the cache without worrying
3710 about case-sensitivity, even though, for example nicknames are
3713 * Fixed a bug in server with channel message sending. It put
3714 wrong ID type as destination ID. The affected file
3715 silcd/packet_send.c.
3717 * silc_idcache_del_by_context now deletes from all hash tables
3718 by context. Affected file lib/silccore/idcache.c.
3720 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Changed the client library to use the new ID Cache interface.
3723 Changes around the source tree.
3725 * Added silc_hash_table_rehash_ext to rehash with specific
3726 hash function. Affected file lib/silcutil/silchashtable.[ch].
3728 * Added silc_hash_string_compare to compare two strings in the
3729 hash table. Affected file lib/silcutil/silcutil.[ch].
3731 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Added new function silc_idcache_del_by_context into the
3734 lib/silccore/idcache.[ch].
3736 * Changed the server's ID list routines to use the new ID Cache
3737 interface. Changes around the source tree.
3739 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Added silc_hash_table_del[_by_context]_ext functions in to the
3742 lib/silcutil/silchashtable.[ch].
3744 Removed silc_hash_table_find_all* routines and added new
3745 silc_hash_table_find_foreach to replace them.
3747 Added silc_hash_table_replace_ext function as extended
3748 replacing function. Separated the simple hash table interface
3749 from the extended hash table interface in the file
3750 lib/silcutil/silchashtable.h.
3752 * Fixed minor bugs and changed it to use some of the new
3753 hash table functions in lib/silccore/idcache.c
3755 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Added new function silc_hash_table_find_all to return all keys
3758 in the hash table by the specified key. As the hash table is
3759 collision resistant it also makes it possible to have several
3760 duplicate keys in the hash table. This function may be used to
3761 find all of the keys from the hash.
3763 Added user_context arguments to the SilcHashFunction,
3764 SilcHashCompare and SilcHashDestructor to deliver user specified
3767 Added new fuctions silc_hash_table_find[_all]_ext to do
3768 extended lookup with specified hash and compare functions and
3769 specified user contexts.
3771 Added new function silc_hash_table_add_ext to add the key
3772 with specified hash function and user context.
3774 Added new function silc_hash_table_foreach to traverse all
3775 entrys in the hash table. Added SilcHashForeach callback
3778 Added new function silc_hash_table_del_by_context to delete
3779 the entry only if the context associated with the key matches.
3781 Affected files are lib/silcutil/silchashtable.[ch].
3783 * Removed silc_hash_[server/client/channel]_id and added just
3784 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3785 silc_hash_id_compare to compare two ID's using as the hash table
3786 comparison function. Added also silc_hash_data to hash
3787 binary data and silc_hash_data_compare to compare it.
3789 * Removed silc_idlist_find_client_by_hash as it is not needed
3790 anymore. Affected file silcd/idlist.[ch].
3792 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3793 to use internally the SilcHashTable. The new ID Cache is a lot
3794 faster than the old one. Some of the ID Cache interface was also
3795 rewritten and obsolete and stupid functions were removed.
3797 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Added entry_count field to the SilcHashTable to keep the number
3800 of the entries in the table. Implemented the function
3801 silc_hash_table_rehash. Added new function
3802 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3804 Fixed a minor bug in silc_hash_table_free.
3806 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3807 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3808 into the lib/silcutil/silcutil.[ch].
3810 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Implemented a collision resistant hash table into the
3813 lib/silcutil/silchashtable[ch]. See the header and the source
3814 for the SilcHashTable API.
3816 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Merged dotconf version 1.0.2 into lib/dotconf.
3820 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Do not compile anything in lib/silcsim/* if the SIM support
3823 is not enabled. The tree should now compile without problems
3826 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Compiled the SILC under cygwin. Compiled and tested briefly
3829 without problems. More tests needed. The SIMs didn't compile
3832 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3834 * Fixed possible crash in silc_get_username in the
3835 lib/silcutil/silcutil.c.
3837 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Fixed a va_arg in silc/client_ops.c.
3841 * Oops, RC5 routines were named AES and caused some problems
3842 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3844 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Added new SilcIDIP structure into the lib/silccore/id.h and
3847 replaced the old `ip' fields from all SILC ID's to that type.
3848 This is a step towards IPv6 support.
3850 The silc_id_get_len takes now the ID as an extra argument.
3851 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3852 both IPv4 and IPv6 based ID's.
3854 The affected files are lib/silccore/id.[ch] and other files
3855 around the tree using these routines.
3857 * Removed the ID length arguments in server from various
3858 silc_server_send_notify_* routines -> they are not needed
3861 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Fixed memory leak in silc_encode_pem_file in the file
3864 lib/silcutil/silcutil.c.
3866 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Check minor version as well in the SKE. Affected files are
3869 silcd/protocol.c and lib/silcclient/protocol.c.
3871 * Added --identifier option to the server so that an identifier
3872 can be when creating the public key for the server. Affected
3873 file is silcd/silcd.c.
3875 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3876 lib/silccrypt/silcpkcs.c.
3878 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Register default ciphers and stuff when using -C option with
3881 the server. Affected file sildc/silcd.c.
3883 * Put back the servers public key filename format, it is better
3884 than the new one. For now, the client keys are saved with the
3885 new filename format. The affected file silc/client_ops.c.
3887 * Implemented the Cipher API for the rest of the ciphers that
3888 did not implement it or implemented it the wrong way.
3890 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Register default ciphers and stuff when using the -S option
3893 in the client. Affected file silc/silc.c. Same also when
3894 creating new key pair with -C option.
3896 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Fixed the silc_verify_public_key client operation function to
3899 save the public keys differently. The fingerprint is now
3900 used as filename and not the hostname. This way also the
3901 client keys are saved uniquely and not with hostnames. The
3902 affected file is silc/client_ops.c.
3904 * Trimmed the silc_hash_fingerprint function to remove extra
3905 whitespaces from the end of the fingerprint. The affected
3906 file is lib/silccrypt/silchash.c.
3910 * Added silc_cipher_register_default function to register all
3911 default ciphers. It can be used when configuration files
3912 does not exist and the application does not want any specific
3913 ciphers in any specific order.
3915 The SilcDList is now used as silc_cipher_list dynamically
3916 allocated cipher list. Removed the static list all together
3917 and now all ciphers must be allocated to the dynamic list.
3918 The silc_cipher_alloc routine was changed to check only the
3921 All silc_cipher_* routines that used to return int returns
3924 The affected files lib/silccrypt/silccrypt.[ch].
3926 * The same thing was done to silc_hash_* as for silc_cipher_*
3927 routines. Affected files lib/silccrypt/silchash.[ch].
3929 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3930 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3931 Added also silc_pkcs_[un]register[_default] functions.
3932 Removed the data_context from the PKCS API.
3934 * Added silc_hmac_register_default function to register default
3935 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3936 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3937 to unregister all hmacs at once.
3939 * Register the default ciphers, hash functions, PKCSs and HMACs
3940 if client's configuration file does not exist. The affected
3943 * The client did not load the hash functions from the SIM
3944 modules at all. Added support for this. Affected file is
3945 silc/clientconfig.c.
3947 * When decoding public key with silc_pkcs_public_key_decode, check
3948 the supported algorithm only if PKCS are registered. Affected
3949 file lib/silccrypt/silcpkcs.c. The same was done with the
3950 silc_pkcs_private_key_decode.
3952 * Fixed the SILC List routines to keep the list always in order.
3953 It used to change the list's order when traversing the list but
3954 not it preserves the order. Affected file lib/trq/silclist.h.
3956 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Added the client library to use the SilcSocketConnection's
3959 reference counter (by silc_socket_dup) to prevent the bug that
3960 the socket object may be freed underneath async operation.
3962 * The name resolv library checking fixes in the configure.in.pre.
3965 * Created new version of the protocol drafts for future
3966 development. The -03 drafts are the ones that will be changed
3967 in the trunk now and the -02 will remain as they are.
3969 * Send list of CUMODE notifys to the router when announcing
3970 the channel users to the router. Affected file silcd/server.c.
3971 If the router receiving channel founder CUMODE for a channel
3972 that already has channel founder it will send CUMODE notify
3973 to the sender to remove the channel founder rights from the
3974 announced client. Affected file silcd/packet_receive.c.
3976 * The CUMODE notify may now use Server ID as well as the entity
3977 who changes the mode. Updated protocool specs.
3979 * Updated INSTALL and README files.
3981 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * New web pages in the http://silc.pspt.fi. The pages was
3988 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Implemented the [DenyConnectin] config section in the server.
3991 Added silc_server_config_denied_conn to check whether incoming
3992 connection is denied. Affected file silcd/serverconfig.[ch].
3994 * Do not check the ports when checking the incoming configuration
3995 data if the port is 0, meaning any. Affected file is
3996 silcd/serverconfig.c.
3998 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Fixed buffer overflow in silc_string_compare in the file
4001 lib/silcutil/silcutil.c.
4003 * Fixed double free in silc_server_command_leave in the file
4006 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Fixed the version checking in the server. Affected file is
4011 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Fixed the configuration data fetching when accepting new
4014 connections in the server. Affected file silcd/server.c.
4016 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Added `sender_entry' argument to the function
4019 silc_server_packet_relay_to_channel so that we can check
4020 whether some destination actually belongs to the same route
4021 the sender belongs (ie, we must not resend the packet to the
4022 sender). Affected file silcd/packet_send.[ch].
4024 * Added `servername' field to the SilcClientEntry in the server
4025 to hold the name of the server where client is from. Affected
4026 file is silcd/idlist.h.
4028 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Moved the channel message encrypting in the router betwen
4031 router connections from silc_server_channel_message to the
4032 silc_server_packet_relay_to_channel since we want to check
4033 whether we have anybody channel before encrypting anything.
4034 Affected files silcd/packet_[receive/send].c.
4036 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Fixed the [AdminConnection] server config section to support
4039 multiple entries. Affected file silcd/serverconfig.c.
4041 * Added support into the server to check the validity of the
4042 incoming connection before executing any KE or authentication
4045 * The connection configuration is now saved to the KE and
4046 connection auth protocol contexts and not fetched anymore in
4047 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4049 * The local hosts listenning address and port is also resolved
4050 now when starting the server. We want to have the socket object
4051 to include the real address and port for the listener. Added
4052 new function silc_net_check_local_by_sock into the files
4053 lib/silcutil/silcnet.[ch].
4055 * Fixed a broadcast bug in server -> do not broadcast if we
4058 * Fixed a routing bug. Do not route broadcast packets ever.
4059 Broadcast packets must be processed always and not routed since
4060 they may be destined to some other host than yourself and thus
4061 would get routed without no good reason. Affected file is
4064 * Added function silc_server_config_is_primary_route to check
4065 whether primary router connection has been configured (a router
4066 configuration that we are initiating). If there is not, we
4067 will assume that there is only two routers in the SILC network
4068 and we will use the incoming router connection as our primary
4069 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4071 * Changed the order of the broadcasting. Broadcast _after_ the
4072 packet has been processed not before. Affected file is
4075 * Fixed a [ClientConnection] parsing bug. The port was never
4076 parsed correctly thus resulting to port 0. Affected file
4077 silcd/serverconfig.c.
4079 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4080 argument and did not set the broadcast packet flag. Affected
4081 file silcd/packet_send.c. Fixed same bug in the function
4082 silc_server_send_notify as well.
4084 * If we receive NEW_ID packet for our own ID in the server, ignore
4087 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Removed the nickname from the Private Message Payload.
4092 Updated the code and the protocol specs.
4094 * Updated protocol specs for submitting to the IETF.
4096 * Tweaked the Random Number Generator a bit. Affected file
4097 lib/silccrypt/silcrng.c. Exported a new function
4098 silc_rng_[global]_add_noise which can be used to add more
4101 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Do not parse packets with different timeout when protocol
4104 is active -> may cause problem with rekey. Affected file
4107 * When server receives signoff notify it must not create
4108 new channel key if the client is on any channels since the
4109 sender of the signoff notify will create it.
4111 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Added printing of error messages during SKE protocol from the
4114 failure packet sent by server during SKE. Affected file
4117 * Removed the client's failure_callback handling with timeout
4118 and handle it immediately when received.
4120 * The SKE library returned wrong type in SUCCESS and FAILURE
4121 packets. They must be 32 bit MSB not 16 bit MSB.
4123 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Ok, rewrote the logic of the re-key and now it seems to work.
4126 I tested it on high traffic with frequent re-keys without
4127 problems. Added hmac_receive (and renamed hmac to hmac_send)
4128 in SilcClientConnection in lib/silcclient/client.h and
4129 in SilcIDListData in silcd/idlist.h. Also, removed the
4130 SilcPacketParserContext's cipher and hmac fields as they are
4131 not needed anymore and actually caused some problems when
4132 the ciphers and hmac's changed underneath the packet parser.
4134 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * If re-key protocol is active then process the incoming packets
4137 synchronously since we must assure that icoming packets encrypted
4138 with the old key is processed before the new keys is set to
4139 use. This is true other packets than for REKEY packets.
4140 Affected file silcd/server.c. The same was done to client library
4141 as well, affected file lib/silcclient/client.c.
4143 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Fixed bug in client and server to accept the force send if
4146 the packet is send from silc_[server/client]_packet_process
4147 function. Otherwise the packets are never delivered, oops.
4149 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Disable force sending of packets when REKEY protocol is active.
4152 We must assure that no packet is sent directly when rekey is
4153 performed. All packets must be sent through packet queue.
4154 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4155 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4156 function is silc_[server/client]_packet_send_real to check
4159 * Replaced the SIM paths from example config files to
4160 /usr/local/modules. Also, make install creates now
4161 /usr/local/silc/logs directory to hold all the SILC server
4164 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Made the configure.in.pre work on Solaris. Patch by salo.
4168 * Made all ciphers compatible with non-x86 machines. Defined
4169 CBC mode macros into lib/silccrypt/ciphers_def.h.
4171 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Fixed the make install.
4175 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * When MAC computation fails the silc_packet_decrypt returned 0
4178 even though it was supposed to return -1. Fixed this. The
4179 affected file is lib/silccore/silcpacket.c.
4181 * Do not replace the config files in /etc/silc (in make install)
4182 if they already exist. Affected file ./Makefile.am.
4184 * Do not send re-key packets immediately but through packet queue.
4185 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4187 * Changed silc_net_check_host_by_sock to return FALSE if the
4188 IP/DNS could not be resolved. Though, it returns the IP address
4189 now even if it could not resolve it (but returns also FALSE).
4190 Affected file lib/silcutil/silcnet.[ch].
4192 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Added silc_pkcs_decode_identifier to decode the public key's
4195 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4196 Added also silc_pkcs_free_identifier. Added also new context
4197 SilcPublicKeyIdentifier.
4199 * Added -S option to the silc client. It is used to dump the
4200 contents of the specified public key file.
4202 * Changed the PKCS api to return the public key length when
4203 setting the public key.
4205 * Fixed a fatal bug in the public and private key file loading.
4206 Affected file lib/silccrypt/silcpkcs.c.
4208 * Execute the packet parsing for client with zero (0) timeout
4209 if the protocol is active. Affected file silcd/server.c.
4211 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Made the key generation options to the silcd program. Added
4214 -C option, equivalent to client's option.
4216 * Added new [ServerKeys] config section to the server. It
4217 configures the server's public and private key.
4219 * Defined generic Public Key Payload into the protocol
4220 specification to send specific type of public keys and
4223 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4224 public key or certificate.
4226 * Implemented the GETKEY command to the server and to the
4227 client library and on user interface.
4229 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Made preliminary `make install' work.
4233 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Added SilcServerRekey context into silcd/idlist.h.
4237 * Added the PFS support as defined in the specification to the
4238 SKE protocol. Affected files lib/silcske/*.c.
4240 * Added `ske_group' field to the SilcServerRekey context to hold
4241 the number of the SKE group that is used with PFS in re-key.
4242 Affected file silcd/idlist.h.
4244 * Added PFS re-key support to the server. Affected file is
4247 * Added silc_protocol_cancel to cancel execution of the next
4248 state of the protocol. Affected file is
4249 lib/silccore/silcprotocol.[ch].
4251 * Added the re-key support with and without PFS to the client
4252 library. Re-key is performed once in an hour, by default.
4254 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4255 Added silc_client_rekey_callback and silc_client_rekey_final.
4256 Affected files are lib/silcclient/protocol.[ch] and
4257 lib/silcclient/client.[ch].
4259 * Removed the `hmac_key' and `hmac_key_len' fields from the
4260 SilcClientConnection structure; not needed. Affected file is
4261 lib/silcclient/client.h.
4265 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Do not ask whether user wants to use the negotiated private key
4268 for private messages, just use it. Affected file is
4269 silc/local_command.c.
4271 * Added `send_enc_key' and `enc_key_len' fields to the
4272 SilcIDListData structure since they are needed in the re-key
4273 phase. Affected file is silcd/idlist.[ch].
4275 * Implemented the simple re-key protocol into the server.
4276 Affected files silcd/server.c and silcd/protocol.[ch]. The
4277 re-key will be performed once in an hour, by default.
4279 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4280 Added silc_server_rekey, silc_server_rekey_callback and
4281 silc_server_rekey_final.
4283 * Removed Tunneled flag from the protocol. Updated the code
4284 and the specifications.
4286 * Adde `pfs' field to the SilcIDListData to indicate whether
4287 the PFS is to be performed in the re-key. Affected file is
4290 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4293 int64 of at least the xintXX size. If void * is less that 4
4294 bytes uint32 * will be used. Defined bool as boolean.
4296 * Changed _ALL_ unsigned long and unsigned int to uint32,
4297 unsgined short to uint16 in the source tree.
4299 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4300 not handle clients that has entry->data.registered == FALSE.
4301 They are not in the network anymore. Affected file is
4304 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Implemented the sending of the SERVER_SIGNOFF notify in the
4307 server. Affected file is silcd/server.c.
4309 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4310 Added also silc_notify_payload_encode_args into the
4311 lib/silccore/silcnotify.[ch].
4313 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4314 Affected file silcd/packet_receive.c.
4316 * Implemented the SERVER_SIGNOFF notify handling in the client
4317 library. Affected file lib/silcclient/client_notify.c. Also,
4318 implemnted the printing of the SERVER_SIGNOFF info to the
4319 application. Affected file silc/client_ops.c.
4321 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4322 if the deleting was successful. Affected file silcd/idlist.[ch].
4324 * Added support for public key authentication in the connection
4325 authentication protocol in the client library. Affected file
4326 lib/silcclient/protocol.c.
4328 * Changed the server's silc_idlist_get_clients_by_* interface
4329 to support already allocated array so that new entries may be
4330 added to pre-allocated array. Affected file silcd/idlist.[ch].
4331 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4332 and command replies.
4334 * All command reply functions in the server now calls the
4335 pending command callback even if error occured. This way the
4336 error will be delivered to the client as well. Affected files
4337 silcd/command.c and silcd/command_reply.c.
4339 * Fixed INFO command to return local server's info if no server
4340 was provided. Affected file lib/silcclient/command.c.
4342 * Removed RESTART command for good. Updated the code and the
4345 * Rewrote parts of the task system. It is a bit simpler now.
4346 Removed unsued task priorities. The affected files are
4347 lib/silcutil/silctask.[ch].
4349 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Moved the USERS printing from the library to the application.
4352 Affected files lib/silcclient/command.c and silc/client_ops.c.
4354 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Added channel key re-key support. The re-key is perfomed
4359 only by the router and is done once in an hour. Added `rekey'
4360 field to the SilcChannelEntry in the server. Affected files
4361 silcd/server.c and silcd/idlist.h.
4363 * Added silc_task_unregister_by_context into the file
4364 lib/silcutil/silctask.[ch].
4366 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Added SILC_UMODE_GONE mode to indicate when the client is not
4369 present in the SILC network. Added also support to the local
4370 command AWAY that will set this mode. Added support of showing
4371 "xxx is gone" in WHOIS command. The USERS command shows the
4372 gone status as well.
4374 * Fixed setting server and router operator privileges in the
4375 server's UMODE command. Affected file silcd/command.c.
4377 * Merged the SKE KE1 and KE2 payloads into one payload. The
4378 new KE payload is equivalent to the old KE2 payload.
4380 Cleaned up the SKE Start Payload parsing. It now uses the
4381 simple buffer unformatting to do the parsing. A lot faster
4384 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4385 to the SKE that is used to indicate whether both of the SKE
4386 parties should perform authentication. By default only the
4387 responder performs authentication. By setting this flag also
4388 the initiator must do authentication. By default it is unset
4389 since in normal SKE case, client to server connection, only
4390 the responder should do authentication. When doing SKE between
4391 two clients both should perform authentication. Updated the
4392 code and the protocol specs.
4394 * A little fix to IDENTIFY command in the server. Search the
4395 client first by hash not nickname. Affected file is
4398 * Fixed the silc_client_close_connection to support closing
4399 the client to client connections wihtout deleting too much
4400 data. Affected file lib/silcclient/client.c.
4402 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4403 are received if protocol used to be active but is not anymore
4404 the application would crash due to NULL pointer dereference.
4405 Affected files silcd/server.c and lib/silcclient/client.c.
4407 * Added `hash' field to the SilcClientConnection to include
4408 the hash function negotiated in the SKE protocol.
4410 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4411 to set the channel founder authentication data. A client can
4412 claim the founder rights later by providing the authentication
4413 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4414 This way the channel founder can regain the channel founder
4415 privileges even it is left the channel. This works only on
4416 local server and the client must be connected to the same
4417 server to be able to regain the founder rights. Updated the
4418 protocol specs accordingly.
4420 Added support to the CMODE command in the client to set the
4421 founder auth data. Read the README to see how to set it.
4423 Added support to the CUMODE command to claim the founder
4424 rights. Read the README to see how to do it.
4426 Added support for the founder authentication to the Channel
4427 Entry in the server. Affected file silcd/idlist.h.
4429 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4430 server's CMODE command. Affected file silcd/command.c.
4432 * Added the following new functions into lib/silccore/silcauth.[ch]:
4433 silc_auth_get_method and silc_auth_get_data.
4435 * The server now saves the remote hosts public key to the
4436 SilcIDListData pointer. Affected file silcd/protocol.c.
4438 * The normal server now does not remove the channel entry from
4439 the cache if the founder authentication data is set. It used
4440 to remove it if the founder was the last one on the channel on
4441 the server and left the channel. The auth data is saved and
4442 if the channel is re-joined later the old entry is used with
4443 the old auth data. Affected files silcd/command_reply.c and
4446 * Removed the `pkcs' field from the SilcIDListData structure
4447 in the server; it is not used. Affected file silcd/idlist.h.
4449 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Fixed packet processing on slow links. Partial packets were
4452 never re-processed because the incoming data buffer was cleared
4453 by the application. Application must not directly clear the
4454 sock->inbuf, the packet processing routines handle it. Fixed
4455 this in client library and in server.
4457 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Fixed the WHOIS and IDENTIFY send reply function to really
4460 check whether to send list or just one entry. Affected file
4463 * Cleaned up the LEAVE command's channel key distribution. The
4464 affected file silcd/command.c.
4466 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4467 can enforce the channel mode as well. In that case the ID
4468 includes the ID of the server. The code now enforces the
4469 mode change if the router have different mode than the server.
4471 * The notify client operation with CMODE_CHANGE notify can now
4472 return NULL client_entry pointer if the CMODE was not changed
4473 by client. Application must check for this.
4475 * Added <Server ID> argument to INFO command to support server
4476 info fetching by Server ID.
4478 * Added silc_server_announce_get_channel_users to get assembled
4479 packets of channel users of the specified channel. Affected
4480 file silcd/server.[ch].
4482 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4483 was freed underneath the ID Cache.
4485 * Re-announce clients when the server received CHANNEL_CHANGE
4486 notify from the router. Affected file silcd/packet_send.c.
4488 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4491 crashed since it did not handle the fact that there is no cipher
4492 called "3" and didn't check the error condition. Now fixed.
4494 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4495 flag. It can be used to send message requests.
4497 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Implemented the RESTART command in the client.
4501 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4502 notice type messages. Added notice printing to the user
4505 * The channel keys are not re-generated if the channel's mode
4506 is PRIVKEY, ie private key on the channel exists. Affected
4507 files silcd/server.c and silcd/command.c.
4509 * Fixed a little bug in channel message delivery when channel
4510 private keys are set in the server. Affected file is
4511 silcd/packet_send.c.
4513 * Changed the setting on channel->on_channel = TRUE from the
4514 silc_client_save_channel_key to the JOIN command reply. The
4515 key payload is not received if the private channel key is set.
4516 Affected file lib/silcclient/command_reply.c and the
4517 lib/silcclient/client_channel.c.
4519 * When the CMODE_CHANGE notify is sent and the channel private
4520 key mode is removed the channel key must be re-generated in
4521 other cells as well. Added this support for the router in the
4522 silcd/packet_receive.c.
4524 * Added new local command NOTICE to send notice message on
4525 channel. Affected file silc/local_command.[ch].
4527 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Added new local command ME to the client. It is used to send
4530 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4531 some action. Affected file silc/local_command.[ch].
4533 * Changed channel_message and private_message client operations
4534 to deliver the message flags to the application. Added also
4535 the `flags' arguments to the silc_client_send_channel_message
4536 and silc_client_send_private_message functions. Affected file
4539 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Redefined the Private Message Payload to support private message
4542 keys and to support the new private message flags. Updated
4543 the protocol specs. Flags makes it possible to have for example
4544 CTCP style messages.
4546 * Added new type SilcPrivateMessagePayload and defined an API
4547 for it in the lib/silcclient/silcprivate.[ch].
4549 * Tested private message private keys successfully. Tested the
4550 private message key set, unset and list commands with the new
4553 * Redefined the Channel Message Payload to include the channel
4554 message flags (equal with private message flags) to support
4555 for example CTCP style messages.
4557 * Defined some of the message (for channel and private message)
4558 flags. Updated the protocol specs and added the flags to the
4559 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4561 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Added SilcKeyAgreementStatus type to the key agreement routines
4564 to indicate the current status and error if one occured.
4565 The status types are defined in the lib/silcclient/silcapi.h.
4567 * Added new local command KEY that is used to set and unset private
4568 keys for channels, set and unset private keys for private messages
4569 with remote clients and to send key agreement requests and
4570 negotiate the key agreement protocol with remote client. The
4571 key agreement is supported only to negotiate private message keys,
4572 it currently cannot be used to negotiate private keys for channels,
4573 as it is not convenient for that purpose.
4575 * Fixed a minor pending callback setting bug in the function
4576 silc_client_get_client_by_id_resolve, now the function works.
4577 Affected file lib/silcclient/idlist.c.
4579 * Added function silc_net_get_local_port to get local bound
4580 port by socket. Added to lib/silcutil/silcnet.[ch].
4582 * Added `sockets' and `sockets_count' fields to the SilcClient
4583 object. They hold the sockets of the listenning sockets in
4584 the client. Listenning sockets may be for example the key
4585 agreement server. Affected file lib/silcclient/client.[ch].
4586 Added functions the silc_client_add_socket and the
4587 silc_client_del_socket. They are exported to the application
4590 * Added ~./silc/clientkeys to support other client's public keys.
4592 * Renamed verify_server_key client operation to verify_public_key
4593 and added one argument to indicate the type of the connection
4594 (server, client etc.).
4596 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Added silc_server_connection_auth_request to handle the
4599 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4600 silcd/packet_receive.[ch].
4602 * Added silc_server_send_connection_auth_request into the
4603 silcd/packet_send.c to send the connection auth request packet.
4605 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4608 * Fixed the public key authentication in responder side in the
4609 server. The `auth_data' pointer includes the SilcPublicKey
4610 not the path to the public key. Affected file silcd/protocol.c.
4612 * Implemented the public key authentication in the initiator side
4613 in the server. Affected file silcd/protocol.c.
4615 * Removed the [RedirectClient] config section from the server
4616 configuration. Is not needed and I don't want to implement it.
4618 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Cleaned up the CMODE command in the server. It now works
4621 correctly and supports all the modes defined in the protocol.
4622 Affected file is silcd/command.c.
4624 * Added `hmac_name' field to the SilcChannelEntry in the server
4625 to hold the default HMAC of the channel. It can be set when
4626 creating the channel (with JOIN command). Affected files
4629 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4630 type to indicate the change of the current cipher and hmac
4631 on the channel. Client can safely ignore the <cipher> argument
4632 (if it chooses to do so) since the CHANNEL_KEY packet will
4633 force the channel key change anyway. The <hmac> argument is
4634 important since the client is responsible of setting the new
4635 HMAC and the hmac key into use.
4637 * Fixed the CMODE command in the client library as well.
4639 * Tested CMODE command in router environment successfully.
4641 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Show the version of the remote client (or server) when connecting
4644 to the server. It is logged to the log file. Affected file
4645 is silcd/protocol.c.
4647 * Fixed the KILLED notify handling in the client library. The
4648 client must be removed from all channels when receiving the
4651 Also, do not remove the client entry when giving the KILL
4652 command but when the KILLED notify is received.
4654 * Removed silc_idlist_find_client_by_nickname from the server.
4655 Not needed anymore. Affected files silcd/idlist.[ch].
4657 * Implemented the CHANNEL_CHANGE notify type handling to the
4658 server. Affected file silcd/server.c.
4662 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Added silc_server_send_notify_invite to send the INVITE
4665 notify between routers.
4667 * Implemented the INVITE command correctly to the server.
4669 * Implemented the INVITE notify type handling in the server.
4671 * Implemented the INVITE command to the client library and on the
4674 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added function silc_server_get_client_resolve to find the
4677 client entry by ID from all ID lists and then resolve it
4678 (using WHOIS) if it cannot be found. Affected file is
4681 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Implemented the BAN command to the client library.
4685 * The JOIN command in the server now checks the invite list
4688 * Changed the silc_command_reply_payload_encode_va and the
4689 silc_command_payload_encode_va to support that if argument is
4690 NULL it ignores and checks the next argument. Affected file
4691 lib/silccore/silccommand.c.
4693 * Added silc_server_send_notify_ban to send the BAN notify
4694 type between routers.
4696 * Chaned the silc_notify_payload_encode to support that if
4697 argument is NULL it ignores and checks the next argument.
4698 Affected file lib/silccore/silcnotify.c.
4700 * Tested ban lists in router environment successfully.
4702 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Implemented BAN command to the server, in silcd/command.[ch].
4706 * Removed the BAN and INVITE_LIST modes from the CMODE command
4709 * Added function silc_string_match to regex match two strings.
4710 Affected files lib/silcutil/silcutil.[ch].
4712 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Redefined parts of the SilcChannelEntry in the server to support
4715 the new ban and invite lists.
4717 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Redefined the INVITE command. The same command can be used to
4720 invite individuals to the channel but also to manage the invite
4721 list of the channel (to add to and remove from the invite list).
4722 Updated the protocol specs.
4724 * Added new command SILC_COMMAND_BAN that can be used to manage
4725 the ban list of the channel. Updated the protocol specs.
4727 * Removed the channel modes: the SILC_CMODE_BAN and the
4728 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4729 in the CMODE command. The equivalent features are now available
4730 using INVITE and BAN commands. Updated the protocol specs.
4732 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4733 in the network about change in the current ban list. The notify
4734 type is not used by the client.
4736 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4737 support the invite lists.
4739 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Added new function silc_string_regexify that converts string
4742 including wildcard characters into regex string that can
4743 be used by the GNU regex library. Added into the file
4744 lib/silcutil/silcutil.[ch].
4746 Added silc_string_regex_combine to combine to regex strings
4747 into one so that they can be used as one regex string by
4748 the GNU regex library. Added into the file
4749 lib/silcutil/silcutil.[ch].
4751 Added silc_string_regex_match to match two strings. It returns
4752 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4754 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Imported GNU regex to the soruce tree into lib/contrib.
4757 Fixed some compiler warning from the regex.c.
4759 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Fixed MOTD command in the server to work in router environment.
4763 * Fixed the MOTD command in the client library to support
4764 the server argument in the command.
4766 * Added `nickname_len' argument to the silc_idlist_add_client
4767 in the server, as the `nickname' argument may be binary data
4770 * Added silc_idlist_get_channels to return all channels from
4773 * Implemented LIST command to the server. Affected file is
4776 * Implemented the LIST command to the client library and on the
4779 * Added [<user count>] argument to the LIST command reply.
4780 With private channels the user count is not shown.
4782 * Updated TODO and README.
4784 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * The client entry's data.registered must be TRUE even with
4787 global client entry on global client list. The data.registered
4788 is used to check whether the client is anymore in the network,
4789 for example with WHOWAS command so it must be valid.
4791 * Fixed the WHOWAS command in the server. It now actually works
4792 in router environment. Added function into silcd/command_reply.c
4793 silc_server_command_reply_whowas_save.
4795 * Added silc_idlist_purge function to the silcd/idlist.c
4796 to periodically purge the ID Cache.
4798 * Fixed INFO command in the server. It works now in router
4799 environment. Added <server name> argument to the INFO command
4800 reply. Updated the protocol specs.
4802 * Fixed minor bug in silc_idcache_purge to not purge if the
4803 expire value is zero.
4805 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4806 they were buggy because of the WHOWAS information.
4808 * Fixed local command MSG to handle the async resolving of
4809 the remote client properly. It used to fail the first MSG.
4810 Affected file silc/local_command.c.
4812 * Added `data_len' field to SilcIDCache context.
4814 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Update TODO. Todo in commands in the server.
4818 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4821 used by routers as broadcast packet to inform other routers
4822 about the changed user mode.
4824 Implemented the notify handling in the server. Affected file is
4825 silcd/packet_receive.c. Added the function
4826 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4828 * Added new generic Channel Payload and deprecated the New Channel
4829 Payload. The New Channel Payload is now the generic Channel
4832 * Added new argument `mode' to the silc_server_send_new_channel
4833 as it is required in the Channel Payload now.
4835 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4836 and created a new and real SilChannelPayload to represent the
4837 new generic Channel Payload. Implemented the encode/decode
4838 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4840 * Added silc_server_get_client_channel_list to return the list
4841 of channels the client has joined for WHOIS command reply.
4842 Affected file silcd/server.[ch].
4844 * Implemented the channel list sending in the WHOIS command reply
4845 in server and in the client.
4847 Implemented the channel list displaying on the user interface
4848 as well. Affected file silc/client_ops.c.
4850 * Added silc_channel_payload_parse_list to parse list of Channel
4851 Payloads. It returns SilcDList list of SilcChannelPayloads.
4852 Client for example can use this function to parse the list of
4853 channels it receives in the WHOIS command reply. The caller
4854 must free the list by calling silc_channel_payload_list_free.
4855 Affected files lib/silccore/silcchannel.[ch].
4857 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Added one new argument <user mode> to the WHOIS command reply
4860 to return the mode of the user in SILC. Updated the protocol
4863 Implemented it to the server and client.
4865 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Fixed the mode printing on the user interface on joining.
4868 Affected file silc/client_ops.c.
4870 * Implemented the UMODE command and user modes in general to the
4871 client library and to the user interface.
4873 * Implemented the UMODE command to the server.
4875 * The server now sends UNKNOWN_COMMAND error status if client sends
4876 unknown command. Affected file silcd/command.c.
4878 * All server commands now handle the command identifier the right
4879 way when sending the command reply to the client. The client can
4880 use to identify the command replies with the identifier.
4882 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added silc_server_get_client_route to resolve the route to
4885 the client indicated by the client ID. Affected file is
4888 * Added silc_server_relay_packet as general function to relay
4889 packet to arbitrary destination. This deprecates functions
4890 like _send_private_message_key, _relay_notify etc. Affected
4891 file is silcd/packet_send.[ch].
4893 Removed silc_server_send_key_agreement,
4894 silc_server_send_private_message_key and
4895 silc_server_packet_relay_notify functions from the file
4896 silcd/packet_send.[ch].
4900 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4901 server. Affected file silcd/packet_receive.[ch].
4903 * Implemented the KILL command to the client. Implemented the
4904 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4905 Affected files lib/silcclient/command[_reply].c and
4906 lib/silcclient/client_notify.c. Implemented the KILL notify
4907 printing in the user inteface.
4909 * Fixed a lot silc_parse_nick memory leaks from the client
4910 library in the file lib/silcclient/command.c.
4912 * Changed the silc_server_send_notify_on_channels's `sender'
4913 argument from SilcSocketConnection to SilcClientEntry to
4914 check the sender as entry and not as connection object and not
4915 to send to the client provided as argument. The affected file
4916 is silcd/packet_send.[ch].
4918 * The notify packets that are destined directly to the client used
4919 to not to be processed by the server. Now changed that and the
4920 server processes all notify packets. After relaying the packet
4921 to the client the notify packet is processed in the server.
4923 * The silc_server_free_client_data now checks whether there is
4924 pending outgoing traffic for the client and purges the data to
4925 the network before removing the client entry.
4927 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4930 an client is killed from the SILC Network. Updated the protocol
4933 Added new function silc_server_send_notify_killed to the
4934 silcd/packet_send.[ch].
4936 * Added function silc_server_packet_relay_notify to relay notify
4937 packets that are destined directly to a client. In this case
4938 the server does not process the notify packets but merely relays
4939 it to the client. Affected file silcd/packet_send.[ch].
4941 Added also silc_server_packet_process_relay_notify to check
4942 whereto relay the notify. Affected file is
4943 silcd/packet_receive.[ch].
4945 * Implemented the KILL command to the server.
4949 * Added the backup schema desgined last fall to the protocol
4950 specs for everyone to see. The specification is in the
4951 *-spec-xx.txt draft and the packet type definitions for the
4952 backup routers is in *-pp-xx.txt draft. Thusly, added also
4953 new packet type SILC_PACKET_CELL_ROUTERS.
4955 * A big security problem in the implementation discovered. The
4956 signoff of an client did not cause new channel key generation
4957 which it of course should've done. The channel keys must be
4958 always re-generated when client leaves (or signoffs) the channel.
4959 The silc_server_remove_from_channels funtion now handles
4960 the channel key re-generation.
4962 * Added `sender' argument to the silc_server_send_notify_on_channels
4963 to not to send the client provided as argument. Affected file
4964 silcd/packet_send.[ch].
4966 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Implemented OPER and SILCOPER commands into the server and
4971 * Added silc_auth_verify and silc_auth_verify_data to verify
4972 the authentication directly from the authentication payload.
4973 It supports verifying both passphrase and public key based
4974 authentication. Affected file lib/silccore/silcauth.[ch].
4976 * Added `hash' field to the SilcIDListData structure. It is the
4977 hash negotiated in the SKE protocol. Affected file is
4980 * Slight redesigning of the SilcAuthPayload handling routines.
4981 Do not send SilcPKCS but SilcPublicKey as argument.
4983 * Implemented the public key authentication support to the
4984 serverconfig. The public key is loaded from the provided path
4985 and saved as authentication data to void * pointer. Thus,
4986 changed the unsigned char *auth_data to void *auth_data;
4988 * Fixed SHUTDOWN command to send the reply before the server
4989 is shutdown. :) Affected file silcd/command.c.
4991 * Fixed fatal bug in CONNECT command. The hostname was invalid
4992 memory and server crashed. Affected file silcd/command.c.
4994 * Fixed fatal bug in CLOSE command. The server_entry became
4995 invalid but was referenced later in the command. Affected file
4998 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Fixed fatal bug in failure packet handling. Server ignored
5001 the failure and thus crashed when it came.
5005 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5008 that the command may be executed only once in (about) 2 seconds.
5009 The old SILC_CF_LAG flag is same but allows command bursts up
5010 to five before limiting.
5012 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5013 server code. Various commands now includes the CF_LAG_STRICT
5014 flag to disallow any kind of miss-use of the command.
5016 * Fixed the silc_buffer_unformat to not to allocate any data
5017 if the length of the data is zero. It used to allocate the
5018 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5020 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Changed the format of AdminConnection configuration section
5023 in the server. Added username of the admin to the format.
5024 Affected files silcd/serverconfig.[ch].
5026 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5027 to return admin configuration data by host, username and/or
5030 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Implemented WHOWAS command to the server. Added the functions:
5034 silc_server_command_whowas_parse,
5035 silc_server_command_whowas_send_reply,
5036 silc_server_command_whowas_from_client and
5037 silc_server_command_whowas_from_server
5039 * Added <Client ID> argument to the WHOWAS command reply. Updated
5040 the protocol specs accordingly.
5042 * Implemented WHOWAS command and command_reply to the client
5045 Implemented the WHOWAS printing on the user interface.
5047 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Added new argument to the WHOWAS command reply, the real name.
5050 It is an optional argument. Updated the protocol specs.
5052 * Added SilcIDCacheDestructor callback that is registered when
5053 the SilcIDCache is allocated. The callback is called when
5054 an cache entry in the ID Cache expires, or is purged from the
5055 cache. Added into lib/silccore/idcache.[ch].
5057 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5058 to destruct the client entries when the cache entry expires.
5059 Other ID Cache's in server and in the client library ignores
5062 * If the ID Cache entry's `expire' field is zero then the entry
5063 never expires. Added boolean `expire' argument to the
5064 silc_idcache_add function in the lib/silccore/idcache.[ch].
5065 If it is TRUE the default expiry value is used.
5067 * Added silc_server_free_client_data_timeout that is registered
5068 when client disconnects. By default for 5 minutes we preserve
5069 the client entry for history - for WHOWAS command.
5071 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Added support to the server to enforce that commands are not
5074 executed more than once in 2 seconds. If server receives
5075 commands from client more frequently, timeout is registered
5076 to process the commands. Affected file silcd/command.c.
5077 Added new function silc_server_command_process_timeout.
5079 * Changed NICK_NOTIFY handling in client library to check that
5080 if the client's nickname was changed, so there is no need to
5081 resolve anything from the server.
5083 * Removed error printing from the WHOIS and IDENTIFY commands.
5084 If error occurs then it is ignored silently in the client library.
5085 The application, however, may map the received error to
5086 human readable error string. The application currently maps
5087 the NO_SUCH_NICKNAME error to string.
5089 * Made the command status message public to the application. Moved
5090 them from lib/silcclient/command_reply.c to
5091 lib/silcclient/command_reply.h. The application can map the
5092 received command status to the string with the
5093 silc_client_command_status_message function.
5095 * Added check to the server to check that client's ID is same
5096 as the Source ID in the packet the client sent. They must
5099 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Added dist-bzip hook to the Makefile.am to make bzip2
5102 compressed distributions.
5104 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Server now enforces the maximum length for the nickname and
5107 the channel as protocol specification dictates. 128 bytes for
5108 nickname and 256 bytes for channel name.
5110 * Moved the WHOIS printing to the application. The client libary
5111 does not print out the WHOIS information anymore, the application
5112 must do it. Renamed silc_client_command_reply_whois_print to
5113 the silc_client_command_reply_whois_save.
5115 The client's idle time is also sent to the application now, and
5116 the idle is shown on screen.
5118 * Added silc_client_command_reply_identify_save to save the
5119 received IDENTIFY entries.
5121 * Do not check for channel private keys in message sending and
5122 reception if the channel does not have the PRIVKEY mode set.
5123 Affected file lib/silclient/client_channel.c.
5125 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5128 just surfaced after chaning the JOIN procedure.
5130 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Added silc_client_get_clients_by_list to get client entries
5133 from Client ID list, that is returned for example by JOIN
5134 and USERS command replies. The application should use this
5135 function for example when JOIN command reply is received to
5136 resolve the clients already on the channel (library does not
5137 do that anymore as USERS command reply is not used in the JOIN
5138 procedure anymore). Affected files lib/silcclient/silcapi.h and
5139 lib/silcclient/idlist.c.
5141 * JOIN command reply and USERS command reply returns now SilcBuffer
5142 pointers instead of unsigned char pointers when returning
5143 the client list and mode list.
5145 * Added <Client ID> argument to the JOIN command reply, mainly
5146 for the server to identify for which client the command was
5147 originally sent. Updated protocol specs accordingly.
5149 * Added SilcDlist private_key pointer to the SilcChannelEntry
5150 in the client to support the channel private keys. Affected
5151 file is lib/silcclient/idlist.h.
5153 * Added SilcChannelPrivateKey argument to the function
5154 silc_client_send_channel_message so that application can choose
5155 to use specific private ke if it wants to. If it is not provided,
5156 the normal channel key is used, unless private keys are set.
5157 In this case the first (key that was added first) is used
5158 as the encryption key.
5160 * Implemented the support for channel private key handling.
5161 Implemented the following functions:
5163 silc_client_add_channel_private_key,
5164 silc_client_del_channel_private_keys,
5165 silc_client_del_channel_private_key,
5166 silc_client_list_channel_private_keys and
5167 silc_client_free_channel_private_keys
5169 Affected file lib/silcclient/client_channel.c.
5171 * Added the support for the private keys in the channel message
5172 sending and encryption and in the message reception and
5173 decryption. Affected funtions are
5174 silc_client_send_channel_message and silc_client_channel_message.
5176 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Added SKE's key verify callback to the client library's
5179 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5181 * Removed the statement that server (or router) must send USERS
5182 command reply when joining to the channel so that the client
5183 knows who are on the channel. Instead, the client list and
5184 client's mode list is now sent in the JOIN command reply to the
5185 client who joined channel. This is better solution.
5187 * Added function silc_server_get_users_on_channel and function
5188 silc_server_save_users_on_channel to the silcd/server.[ch].
5190 * Removed function silc_server_command_send_users from the
5193 * Do not show topic on the client library anymore. The topic is
5194 sent in the command reply notify to the application and the
5195 application must show the topic now.
5197 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Added client searching by nickname hash into the IDENTIFY and
5200 WHOIS commands in the server as they were clearly missing from
5201 them. Affected file is silcd/command.c.
5203 * Fixed a bug in private message receiving in the client library.
5204 The remote ID was freed and it wasn't supposed, now it is
5207 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Minor fix to the channel payload; allocate the data area, as it
5210 needs to be of specific length.
5212 * If the key agreement port is zero then the operating
5213 system will define the bound port. Affected files are
5214 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5216 * Added new function silc_channel_payload_decrypt into the file
5217 lib/silccore/silcchannel.[ch].
5219 * Moved the channel message etc, check from silc_packet_decrypt
5220 to applications. The library calls now a generic
5221 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5222 when the packet is either normal or special. This was done to
5223 allow more wide range of checking that was not allowed when
5224 the code was in library. Now applications can do virtually any
5225 checks to the packet and return to the library the decision how
5226 the packet should be processed. Affected files are
5227 lib/silccore/silcpacket.[ch].
5229 Added silc_server_packet_decrypt_check to the server and
5230 silc_client_packet_decrypt_check to the client library.
5232 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5233 to send with specified source and destination information.
5235 * Channel message delivery between routers was broken after the
5236 channel key distribution was fixed earlier. The channel key
5237 was used be to distributed to other routers as well which is not
5238 allowed by the protocol. Now this is fixed and channel keys
5239 really are cell specific and the channel message delivery between
5240 routers comply with the protocol specification.
5242 * Fixed various commands in server to check also the global list
5243 for the channel entry and not just the local list. The affected
5244 file silcd/command.c.
5246 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Added assert()s to buffer formatting and unformatting routines
5249 to assert (if --enable-debug) when error occurs. Affected
5250 file: lib/silcutil/silcbuffmt.c.
5252 * Changed to auto-reconnect to check whether the remote host is
5253 router and register the re-connect timeout if it is. It used
5254 to check that whether we are normal server, but router must do
5255 auto-reconnect with another router as well. Affected file
5258 * Removed the [<key len>] option from CMODE command as the cipher
5259 name decides the key length, nowadays. See the defined ciphers
5260 from the protocol specification.
5262 * Added [<hmac>] option to the CMODE command to define the HMAC
5263 for the channel. Added SILC_CMODE_HMAC channel mode.
5265 * Added [<hmac>] option for the JOIN command so that user can
5266 select which HMAC is used to compute the MACs of the channel
5269 * Added Hmac field to the Channel Message Payload. The integrity
5270 of plaintext channel messages are now protected by computing
5271 MAC of the message and attaching the MAC to the payload. The
5272 MAC is encrypted. Now, it is clear that this causes some
5273 overhead to the size of the packet but rationale for this is that
5274 now the receiver can verify whether the channel message decrypted
5275 correctly and also when private keys are set for the channel the
5276 receiver can decrypt the packet with several keys and check from
5277 the MAC which key decrypted the message correctly.
5279 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5280 lib/silccrypt/silccipher.[ch].
5282 * Added silc_hash_len to return the digest length into the
5283 lib/silcrypt/silchash.[ch].
5285 * Rewrote parts of Silc Channel Payload interface in the
5286 lib/silccore/silcchannel.[ch]. The encode function now also
5287 encrypts the packet and parse function decrypts it.
5289 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Fixed a minor formatting bug in the SKE's key material processing.
5292 It actually might have processed the keys wrong way resulting
5295 * Redefined the mandatory HMAC algorithms and added new algorithms.
5296 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5297 and hmac-md5 truncated to 96 bits. The mandatory is now
5298 hmac-sha1-96. Rest are optional (including the one that used
5299 to be mandatory). Rationale for this is that the truncated HMAC
5300 length is sufficient from security point of view and can actually
5301 make the attack against the HMAC harder. Also, the truncated
5302 HMAC causes less overhead to the packets. See the RFC2104 for
5305 * Added new [hmac] configuration section. The SKE used to use
5306 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5307 is of course wrong. The official names that must be proposed in
5308 the SKE are the ones defined in the protocol specification
5309 (hmac-sha1-96 for example). The user can configure any hmac
5310 using any hash function configured in the [hash] section. At
5311 least, the mandatory must be configured.
5313 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5315 * Added HMAC list to the SKE proposal list. It has now both
5316 hash algorithm list and HMAC list. This makes the protocol
5317 incompatible with previous versions. The SKE now seems to work
5318 the way it is supposed to work, for the first time actually.
5320 * Defined plain Hash algorithms to the protocol specification.
5323 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Implemented support for key agreement packets into the server.
5326 Added functions silc_server_key_agreement and
5327 silc_server_send_key_agreement. Other than these functions,
5328 server has nothing to do with this packet.
5330 * Added support for private message key packets into the server.
5331 Added functions silc_server_private_message_key and
5332 silc_server_send_private_message_key.
5336 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5337 called in the protocol's final callback instead in the END
5338 protocol state. This makes a little more sense and in the same
5339 time in client we can use the same protocol routines for normal
5340 key exchange and to key agreement packet handling as well.
5342 * Added to both client's and server's KE protocol context the
5343 SilcSKEKeyMaterial pointer to save the key material. We will
5344 bring the key material to the protocol's final callback by doing
5345 this. The final callback must free the key material.
5347 * Added SKE's packet_send callback into client's KE protocol
5348 context so that the caller can choose what packet sending function
5349 is used. This way we can use different packet sending when
5350 doing normal SKE when doing key agreement packet handling (in
5351 the key agreement packet handling we do not want to encrypt
5354 * Implemented the responder side of the key agreement routines
5355 in the client. The client can now bind to specified port and
5356 accept incoming key negotiation. The key material is passed
5357 to the application after the protocol is over.
5359 * Implemented the processing of incoming Key Agreement packet
5360 in the client. Added function silc_client_key_agreement to
5363 * Implemented the intiator side of the key agreement routines
5364 in the client. The client can now initiate key agreement with
5365 another remote client. The key material is passed to the
5366 application after the protocol is over.
5368 * Created client_keyagr.c to include all the key agreement
5371 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5372 SILC_TASK_CALLBACK except that it is not static.
5374 * Created client_notify.c and moved the Notify packet handling
5375 from the client.[ch] into that file.
5377 * Created client_prvmsg.c and moved all private message and
5378 private message key routines from the client.[ch] into that file.
5380 * Create client_channel.c and moved all channel message and
5381 channel private key routines from the client.[ch] into that file.
5383 * Changed silc_client_get_client_by_id_resolve to resolve with
5384 WHOIS command instead of IDENTIFY command, in the file
5385 lib/silclient/idlist.c.
5387 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Implemented the SKE's responder side to the Client library.
5391 * When FAILURE is received to the protocol do not trust it
5392 blindly. Register a timeout to wait whether the remote closes
5393 the connection as it should do it, only after that process the
5394 actual failure. This was changed to both client and server.
5396 * Added client_internal.h to include some of the structures
5397 there instead of client.h in lib/silcclient/.
5399 * Added function silc_task_unregister_by_callback to unregister
5400 timeouts by the callback function.
5402 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Some "Incomplete WHOIS info" errors has been appearing on the
5405 log files. Took away the entry->userinfo check from WHOIS
5406 reply sending. The entry->userinfo is now " " if client did not
5407 provide one. I thought this was fixed earlier but something
5408 is wrong still. Let's see if the error still appears.
5410 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Fixed a minor bug in the login when the channel key is
5413 re-generated in the server. It used to generate the key in
5414 wrong order and thus caused problems in the channel traffic.
5416 * Fixed a minor bug in channel key distsribution after
5417 KICK command. The key was not sent to the router even though
5420 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Added silc_ske_process_key_material_data as generic routine
5423 to process any key material as the SILC protocol dictates. The
5424 function is used by the actual SKE library but can be used by
5425 applications as well. This relates to the private message keys
5426 and the channel private keys since they must be processed the
5427 same way the normal SILC session keys. The protocol dictates
5428 this. Affected files: lib/silcske/silcske.[ch].
5430 Added also silc_ske_free_key_material to free the
5431 SilcSKEKeyMaterial structure.
5433 * Defined silc_cipher_set_key function to set the key for
5434 cipher without using the object's method function. The affected
5435 files: lib/silccrypt/silccipher.[ch].
5437 * Implemented silc silc_client_add_private_message_key,
5438 silc_client_add_private_message_key_ske,
5439 silc_client_del_private_message_key,
5440 silc_client_list_private_message_keys and
5441 silc_client_free_private_message_keys functions in the
5444 Added functions silc_client_send_private_message_key to send
5445 the Private Message Key payload and silc_client_private_message_key
5446 to handle incoming Private Message Key payload.
5448 * Added Cipher field to the Private Message Key payload to set
5449 the cipher to be used. If ignored, the default cipher defined
5450 in the SILC protocol (aes-256-cbc) is used.
5452 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Removed lib/silcclient/ops.h file.
5456 Redefined parts of the SILC Client Library API. Created new
5457 file silcapi.h that deprecates the ops.h file and defines the
5458 published Client Library API. Defined also private message key
5459 API and channel private key API into the file.
5461 This is the file that the application must include from the
5462 SILC Client Library. Other files need not be included by
5463 the application anymore.
5465 * Added new key_agreement client operation callback and also
5466 defined the Key Agreement library API for the application.
5468 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5471 is used by clients to request key negotiation between another
5472 client in the SILC network. If the negotiation is started it
5473 is performed using the SKE protocol. The result of the
5474 negotiation, the secret key material, can be used for example
5475 as private message key.
5477 Implemented the Key Agreement payload into the files
5478 lib/silccore/silauth.[ch].
5480 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Redefined ciphers for the SILC protocol. Added some new ciphers
5483 and defined the key lengths for the algorithms. Changed the
5484 code accordingly. The default key length is now 256 bits.
5486 * Fixed SKE key distribution function silc_ske_process_key_material
5487 when the key length is more than 128 bits. The default key
5488 length in SILC is now 256 bits.
5490 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5491 to indicate unsupported algorithm.
5493 * Renamed rijndael.c to aes.c and all functions as well.
5495 * Fixed a long standing channel key setting bug in client library.
5496 Weird that it has never surfaced before.
5498 * Fixed bug in channel deletion. If the entire channel is removed
5499 then it must also delete the references of the channel entry
5500 from the client's channel list as the client's channel entry and
5501 the channel's client entry share same memory.
5503 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Implemented CONNECT and SHUTDOWN commands in the client.
5507 * Implemented CLOSE command to the client.
5509 * Added the function silc_idlist_find_server_by_name into the
5510 files silcd/idlist.[ch].
5512 Added the function silc_idlist_find_server_by_conn into the
5513 files silcd/idlist.[ch].
5515 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * DIE command was renamed to SHUTDOWN. Updated the both code
5520 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5521 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5523 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5526 * Added function silc_server_create_connection function to create
5527 connection to remote router. My server implementation actually
5528 does not allow router to connect to normal server (it expects
5529 that normal server always initiates the connection to the router)
5530 so the CONNECT command is only good for connecting to another
5533 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5536 or some other client was kicked from the channel.
5538 Implemented the handling of the notify type to both client
5541 Implemented silc_server_send_notify_kicked to send the KICKED
5542 notify. It is used to send it to the server's primary router.
5544 * Implemented the KICK command into server and client.
5546 * Added `query' argument to the silc_idlist_get_client function
5547 to indicate whether to query the client from server or not if
5550 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5551 to indicate that the client is not channel founder.
5555 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Removed the rng context from SilcPacketContext structure and
5558 changed that the packet routine uses the Global RNG API.
5560 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added support for quit message that client can "leave" on the
5563 channel when it quits the SILC. It is ditributed inside the
5564 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5566 Added silc_server_free_client_data that will take the
5567 signoff message as argument.
5569 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5571 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Updated parts of the protocol specification to keep it up
5576 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5579 payloads in one packet.
5581 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5582 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5583 use now the new List flag.
5585 * Also deprecated the following packet types: REPLACE_ID,
5586 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5588 * Added list support for Notify packet in server.
5590 * Added silc_server_send_notify_channel_change to send the
5591 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5592 the silc_server_send_replace_id.
5594 * Added silc_server_send_notify_nick_change to send the
5595 NICK_CHANGE notify type. Deprecates the function
5596 silc_server_send_replace_id.
5598 * Added silc_server_send_notify_join to send the JOIN notify type.
5599 Deprecates the function silc_server_send_new_channel_user.
5601 * Added silc_server_send_notify_leave to send LEAVE notify type.
5602 Deprecates the function silc_server_send_remove_channel_user.
5604 * Added silc_server_send_notify_cmode and
5605 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5606 types. Deprecates the silc_server_send_set_mode function.
5608 * Added SERVER_SIGNOFF notify type to indicate that server has
5609 quit. This means that all clients on the channel from that
5610 server will drop. This can be also used when netsplit happens.
5612 Deprecated REMOVE_ID packet type since it is not needed anymore
5615 Added silc_server_send_notify_server_signoff to send the
5616 SERVER_SIGNOFF notify type. Deprecates the function
5617 silc_server_send_remove_id.
5619 Added also silc_server_send_notify_signoff to send the
5620 SIGNOFF notify type.
5622 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5623 SILC protocol from this day on. Changed the protocol
5624 specification as well.
5626 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5627 notify type. It is used between routers to notify about
5628 topic changes on a channel.
5630 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5633 * Partly updated the protocol specification to comply with the
5634 changes now made. It is still though a bit outdated.
5636 * The JOIN notify type now takes one extra argument <Channel ID>.
5637 The packet used to be destined to the channel but now the
5638 JOIN type may be sent as list thus it is impossible to
5639 destine it to any specific channel. By adding this argument
5640 it is again possible.
5642 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Added CREDITS file. The CHANGES and CREDITS file will appear
5645 in the distribution as well.
5647 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5650 types in the server's silcd/packet_receive.c.
5652 * Implemented CMODE and CUMODE to work in router environment.
5654 * Fixed minor encoding and decoding buglet from the
5655 lib/silccore/silcmode.c.
5657 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5660 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5662 * Changed all SilcConfigServer* and silc_config_server* to
5663 SilcServerConfig* and silc_server_config*, respectively.
5666 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Associated the ID (client or server ID) to the Authentication
5669 Payload to avoid any possibility of forging. Updated the
5670 protocol specification and the code accordingly.
5672 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * The RSA key length is now save to the RsaKey context in the
5675 key generation process in lib/silccrypt/rsa.c. The key length
5676 is now used to figure out the maximum size of the block allowed
5677 to be encrypted/signed.
5679 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5680 is equivalent to the silc_mp_mp2bin but does not allocate any
5683 * Changed silc_mp_mp2bin API to take length argument. If it is
5684 non-zero then the buffer is allocated that large. If zero, then
5685 the size is approximated using silc_mp_sizeinbase, which however
5688 * Created Global RNG API which is global RNG that application can
5689 initialize. After initializing, any routine anywhere in the
5690 code (including library) can use RNG without allocating a new
5691 RNG object. This was done to allow this sort of use of the
5692 RNG in code that has no chance to allocate RNG object. All
5693 applications currently allocate this and many routines in the
5694 library use this. Affected file lib/silccrypt/silcrng.[ch].
5696 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5697 it to use the Global RNG API.
5699 * Defined Authentication Payload into protocol specification that
5700 is used during SILC session to authenticate entities. It is
5701 used for example by client to authenticate itself to the server
5702 to obtain server operator privileges.
5704 Implemented this payload into the lib/silccore/silcauth.[ch].
5705 Implemented also routines for public key based authentication
5706 as the new protocol specification dictates.
5708 Moved definitions of different authentication methods from
5709 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5711 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5712 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5713 silc_pkcs_verify_with_hash functions into the file
5714 lib/silccrypt/silcpkcs.[ch].
5716 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * The client entry's userinfo pointer must be always valid.
5719 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5720 will fail since it requires the userinfo. Now, the userinfo
5721 is allocated as "" if actual userinfo does not exist. Actually,
5722 it must exist and it is totally Ok to drop client connections
5723 that does not announce the userinfo. However, we will make
5724 this workaround for now.
5726 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5727 to return the remote port by socket.
5729 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5732 SILC_SERVER_PENDING_EXEC and added an new macro
5733 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5734 data or when error occurs while processing the pending command.
5736 Added new argument `destructor' into silc_server_command_pending
5737 and to the SilcServerCommandPending object. This destructor is
5738 now called after calling the pending callback or if error occurs
5739 immediately. If error occurs the actual pending callback won't
5740 be called at all - only the destructor. The destructor may be
5741 NULL if destructor is not needed.
5743 All this applies for client library code as well. Similar
5744 changes were made there as well for the pending commands.
5746 In the client, the application must now allocate the
5747 SilcClientCommandContext with the silc_client_command_alloc
5750 * Added reference counter to the SilcServerCommandContext. Added
5751 function silc_server_command_alloc and silc_server_command_dup
5754 Same type of functions added to the client library for the same
5757 * Removed the cmd_ident from IDListData away since it is now
5758 global for all connections. It is the command identifier used
5759 in command sending and with pending commands. The affected file
5762 * Added reference counter to the SilcSocketConnection objecet to
5763 indicate the usage count of the object. The object won't be
5764 freed untill the reference counter hits zero. Currently only
5765 server uses this, and client ignores it. The client must be
5766 set to use this too later. The affected files are
5767 lib/silccore/silcsockconn.[ch]. Added also the function
5768 silc_socket_dup to increase the reference counter.
5770 This was mainly added because it is possible that the socket
5771 is removed underneath of pending command or other async
5772 operation. Now it won't be free'd and proper DISCONNECTING
5773 flags, etc. can be set to avoid sending data to connection that
5774 is not valid anymore.
5776 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5777 the connection. After that it sets SILC_SET_DISCONNECTED.
5778 It is, however, possible that the socket data is not still freed.
5779 The silc_server_packet_process now checks that data is not
5780 read or written to connection that is DISCONNECTED. The socket
5781 get's freed when the reference counter hits zero.
5783 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Changed the client operation API: channel_message operation's
5786 `sender' is now the client entry of the sender, not the nickname
5787 and the `channel' is the channel entry, not the channel name.
5789 In the private_message operation the `sender' is now also the
5790 client entry of the sender not the nickname.
5792 Affected file is lib/silcclient/ops.h and all applications
5793 using the client operations.
5795 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Moved the calling of ops->connect() from connect_to_server_final
5798 into receive_new_id functin since that is the point when the
5799 client is actually allowed to send traffic to network. The
5800 affected file is lib/silcclient/client.c.
5802 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5805 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5806 (if needs broadcasting) instead of broadcasting the packets one
5807 by one which would make a burst in the network traffic.
5809 * Added `broadcast' argument to the functions in silcd/server.[ch]
5810 silc_server_create_new_channel[_with_id] to indicate whether
5811 to send New Channel packet to primary router.
5813 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Added new function into the silcd/server.[ch] files:
5816 silc_server_create_new_channel_with_id to create new channel with
5817 already existing Channel ID.
5819 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5820 lib/silccore/silcpacket.h. This packet is used t send list of
5821 Set Mode payloads inside one packet. Server uses this to set
5822 the modes for the channels and clients on those channels, that it
5823 announced to the router when it connected to it. The protocol
5824 specification has been updated accordingly.
5826 * The silc_server_new_channel did not handle the packet coming
5827 from normal server as it normally does not send that. However,
5828 when it announces its channels it does send it. Implemented
5829 the support for that.
5831 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5832 into the file lib/silccore/id.h.
5834 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Fixed memory leaks in the functions silc_idlist_del_client,
5837 silc_idlist_del_channel and silc_idlist_del_server in the file
5838 silcd/idlist.c. All of those leaked like a sieve.
5840 * Fixed some small memory leaks in the client's function
5841 silc_client_notify_by_server.
5843 * Added functions into silcd/server.c: silc_server_announce_clients,
5844 silc_server_announce_channels and silc_server_announce_server.
5845 These functions are used by normal and router server to announce
5846 to its primary router about clients, channels and servers (when
5847 router) that we own. This is done after we've connected to the
5850 These functions effectively implements the following packet types:
5851 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5852 and SILC_PACKET_NEW_ID_LIST.
5854 * Added new functions into the silcd/packet_receive.[ch]:
5855 silc_server_new_id_list, silc_server_new_channel_list and
5856 silc_server_new_channel_user_list to handle the incoming
5857 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5859 * Added support of changing Channel ID in the function
5860 silc_server_replace_id. If the server that announces a channel
5861 to the router already exists in the router (with same name but
5862 with different Channel ID), router is responsible to send
5863 Replace ID packet to the server and force the server to change
5864 the Channel ID to the one router has.
5866 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5867 client that the Channel ID has been changed by the router. The
5868 normal server sends this to the client. Client must start using
5869 the new Channel ID as the channel's ID.
5871 Implemented handling of this new type into lib/silcclient/client.c
5872 into the function silc_client_notify_by_server.
5874 * Added new function silc_idlist_replace_channel_id into the files
5875 silcd/idlist.[ch] to replace the Channel ID.
5877 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Call silc_server_command_identify_check always when processing
5880 the IDENTIFY command in silcd/command.c
5882 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5885 send keepalive packets. The packet can be sent by clients,
5886 servers and routers.
5888 Added function silc_socket_set_heartbeat into the file
5889 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5890 If not set, the heartbeat is not performed. The actual
5891 heartbeat is implemented in the low level socket connection
5892 library. However, application is responsible of actually
5895 Added silc_server_send_heartbeat to send the actual heartbeat
5896 packet into silcd/packet_send.[ch]. Server now performs
5897 keepalive with all connections.
5899 * Added silc_task_get_first function into lib/silcutil/silctask.c
5900 to return the timeout task with shortest timeout. There was a bug
5901 in task unregistration that caused problems. TODO has been
5902 updated to include that task system must be rewritten.
5904 * The client library will now resolve the client information when
5905 receiving JOIN notify from server for client that we know but
5906 have incomplete information.
5908 * Rewrote parts of silc_server_remove_from_channels and
5909 silc_server_remove_from_one_channel as they did not remove the
5910 channel in some circumstances even though they should've.
5912 * Encryption problem encountered in server:
5914 The LEAVE command used to send the Channel Key packet to the
5915 router immediately after generating it. However, the code
5916 had earlier sent Remove Channel user packet but not immediately,
5917 ie. it was put to queue. The order of packets in the router
5918 was that Channel Key packet was first and Remove Channel User
5919 packet was second, even though they were encrypted in the
5920 reverse order. For this reason, MAC check failed. Now, this
5921 is fixed by not sending the Channel Key packet immediately but
5922 putting it to queue. However, this is more fundamental problem:
5923 packets that are in queue should actually not be encrypted
5924 because packets that are sent immediately gets encrypted
5925 actually with wrong IV (and thus MAC check fails). So, packets
5926 that are in queue should be encrypted when they are sent to
5927 the wire and not when they put to the queue.
5929 However, the problem is that the current system has not been
5930 designed to work that way. Instead, the packet is encrypted
5931 as soon as possible and left to the queue. The queue is then
5932 just purged into wire. There won't be any fixes for this
5933 any time soon. So, the current semantic for packet sending
5936 o If you send packet to remote host and do not force the send
5937 (the packet will be in queue) then all subsequent packets to the
5938 same remote host must also be put to the queue. Only after the
5939 queue has been purged is it safe again to force the packet
5942 o If you send all packets immediately then it safe to send
5943 any of subsequent packets through the queue, however, after
5944 the first packet is put to queue then any subsequent packets
5945 must also be put to the queue.
5947 Follow these rules and everything works fine.
5949 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Added new function silc_server_remove_clients_by_server to
5952 remove all client entries from ID list when the server connection
5953 is lost. In this case it is also important to invalidate all
5954 client entires as they hold the invalid server entry. This
5955 fixes fatal bug when server has lost connection and will reconnect
5958 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Made some sanity checks to silc_server_daemonise like to check
5961 whether the requested user and group actually exists.
5963 * Added sanity check to SKE's silc_ske_responder_finish to check
5964 that the public and private key actually is valid.
5966 * Invalidate the client's nickname when receiving Replace ID
5967 packet and the Client ID is being replaced. This means that the
5968 server will query the nickname if someone needs it (client)
5971 * Sort the ID Cache in client library when the ID Cache data
5972 has changed (needs sorting).
5974 * Do not allow for SILC client to create several connections to
5975 several servers. The client does not support windows right now
5976 and generating multiple connections causes weird behaviour.
5978 Irssi-silc client does support windows and can handle several
5979 connections without problems, see: www.irssi.org and SILC plugin.
5981 * Fixed some places where client was added to the IDList. The
5982 rule of thumb is following (in order to get everything right):
5983 If the client is directly connected local client then the
5984 `connection' argument must be set and `router' argument must be
5985 NULL to silc_idlist_add_client function. If the client is not
5986 directly connected client then the `router' argument must
5987 bet set and the `connection' argument must be NULL to the
5988 silc_idlist_add_client function.
5990 * The funtion silc_server_packet_send_local_channel actually did
5991 not check whether the client was locally connected or not. It
5992 does that now. Fixed a bug related to LEAVE command.
5994 * Fixed Remove Channel User payload parsing bug in server's
5995 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5997 * The server's silc_server_save_channel_key now checks also the
5998 global ID list for the channel as it might not be in the local
5999 list. Fixed a bug related to LEAVE command.
6001 * Is this the end of the [<unknown>] buglet that has been lurking
6002 around for a long time? A little for loop fix in server's
6003 silc_server_command_whois_parse that is used by both IDENTIFY
6004 and WHOIS command. At least, this was a clear bug and a cause
6005 of one type of [<unknown>] buglet.
6007 * WHOIS and IDENTIFY commands call the function
6008 silc_server_command_[whois/identify]_check function even if
6009 we are not router server.
6011 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Added --with-gmp configuration option. If set the GMP
6014 is always compiled in the SILC source tree. If not set then
6015 it is checked whether the system has the GMP3 installed. If
6016 it has then the GMP won't be compiled (the system's headers
6017 and library is used), if it doesn't have it then the GMP is
6018 compiled in the SILC source tree.
6020 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Changed RSA private exponent generation to what PKCS #1
6023 suggests. We try to find the smallest possible d by doing
6024 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6025 not security fix but optimization.
6027 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Added new config entry [Identity] to fork the server and run
6030 it as specific user and group. A patch from Bostik.
6032 * Imported Dotconf configuration library into lib/dotconf.
6033 This will be used to create the SILC configuration files later.
6034 It will appear in the distsribution after this commit.
6036 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * A big code auditing weekend happening. Auditing code for
6039 obvious mistakes, bugs and errors. Also, removing any code
6042 Removed files for being obsolete:
6044 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6045 inline in the file lib/silcutil/silcbuffer.h)
6047 o lib/silcutil/silcbufutil.c (the header has inline versions)
6049 Changed code to fix possible error conditions:
6051 o The buffer formatting routines now check that the destination
6052 buffer really has enough space to add the data. This applies for
6053 both buffer formatting and unformatting
6054 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6055 unformatting was changed to accomodate following rules:
6056 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6057 sent to the function while XXX_*STRING will not allocate or copy
6058 the data into the buffer. Instead it sets the pointer from the
6059 buffer into the pointer sent as argument (XXX_*STRING used to
6060 require that the pointer must be allocated already). This change
6061 makes this whole thing a bit more consistent and more optimized
6062 (note that the data returned in the unformatting with XXX_*STRING
6063 must not be freed now). The routines return now -1 on error.
6065 o Tried to find all code that use buffer_format and buffer_unformat
6066 and added return value checking to prevent formatting and
6067 especially unformatting errors and possible subsequent fatal
6070 o Changed ske->x and ske->KEY to mallocated pointers in
6071 lib/silcske/silcske.h. Fixed possible data and memory leak.
6073 o Added return value checking to all *_parse* functions. Fixed
6074 many memory leaks as well.
6076 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6077 so that buffer overflows would not happen. All code now also
6078 checks the return value as it can fail.
6080 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Added reconnection support to server if the normal server looses
6083 its connection to the router (for example if router is rebooted).
6084 The server performs normal reconnection strategy implemented
6085 to the server. Affected file silcd/server.c.
6087 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Added new packet type SILC_PACKET_SET_MODE that is used to
6090 distribute the information about changed modes (for clients,
6091 channels and clients channel modes) to all routers in the
6092 network. Updated the protocol specification accordingly.
6094 Added functions into silcd/packet_send.c and
6095 silcd/packet_receive.c: silc_server_send_set_mode,
6096 silc_server_set_mode.
6098 Added new files silcmode.[ch] into lib/silccore that implements
6099 the encoding and decoding of Set Mode Payload. Added new type
6100 SilcSetModePayload. Moved the definitions of different modes
6101 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6103 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Oops, a little mistake in server's connection authentication
6106 protocol. The protocol is not ended with FAILURE but with
6107 SUCCESS if the authentication is Ok. :) Affected file is
6110 * Implemented NICK_CHANGE notify handling in server in the file
6111 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6112 the local clients on the channel. After the changing nickname
6113 in router environment snhould work and the [<unknown>] nickname
6114 should appear no more.
6116 The silc_server_replace_id function that receives the Replace ID
6117 payload now sends the NICK_CHANGE notify type also in the file
6118 silcd/packet_receive.c
6120 * Changed WHOIS and IDENTIFY command to support the maximum amount
6121 of arguments defined in protocol specs (3328 arguments). This
6122 fixed a bug that caused problems when there were more than three
6125 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Added extra parameter, command identifier, to the
6128 silc_client_send_command so that explicit command identifier
6131 Changed that ID list routines uses specific command identifier
6132 when sending WHOIS/IDENTIFY requests to the server so that they
6133 can be identified when the reply comes back.
6135 Affected files lib/silcclient/command.[ch],
6136 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6138 * Added `sender' argument to silc_server_packet_send_to_channel
6139 to indicaet the sender who originally sent the packet to us
6140 that we are now re-sending. Ignored if NULL. Affected file
6141 silcd/packet_send.[ch].
6143 * Added some server statistics support in silcd/server_internal.h
6144 SilcServerStatistics structure and around the server code. Also
6145 send some nice statistics information when client is connecting
6148 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Fixed channel ID decoding in server's JOIN command reply in
6151 silcd/command_reply.c
6153 * Fixed braodcasting of replace ID payload to not to send it if
6154 we are standalone server in silcd/packet_receive.c.
6156 * Fixed all channel message sending routines to not to send
6157 packets to clients that has router set, since they are routed
6158 separately in the same function earlier. Affects file
6159 silcd/packet_send.c and all channel packet sending functions.
6161 * In USERS reply, res_argv[i] are not allocated, the table
6162 is allocated. Thus changed that free the table, not its
6165 * In server's whois_check and identify_check if the client is
6166 locally connected do not send any WHOIS commands - they are not
6169 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Fixed some minor bugs in client when sending WHOIS command. The
6172 arguments was in wrong order.
6174 * Removed statis function add_to_channel from server in
6175 silcd/command.c that was previously used with the joining but
6178 * Tested USERS command in router environment successfully with two
6179 routers, two servers and two clients.
6181 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Reorganized the USERS command and command reply in client library
6184 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6185 When the command is given by user we register a pending command
6186 callback that will reprocess the command after the reply has been
6187 received from the server. When reprocessing the packet we then
6188 display the information. Thus, the USERS information is displayed
6189 now in the command callback instead of in the command reply
6190 callback. The processing of the command is same as previously
6191 when server has sent the command reply in the JOINing process.
6193 * Added to USERS command in silcd/command_reply.c to join the client,
6194 we didn't use to know about, to the channel after we've created
6195 a client entry for it. Also, for clienet we did know already still
6196 check whether it is on the channel or not and add it if not.
6198 * Removed silc_server_command_join_notify as the function and its
6201 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Changed the client's pending command handling to the same as the
6204 server's pending command handling. It is also now possible to
6205 execute command reply functions from other command reply
6206 function as the function callbacks for commands and command
6207 replies are one and same. The pending commands are not static
6208 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6209 in client connection context. Thus, pending commands are server
6210 connection specific as it is convenient.
6212 Changed the function silc_client_command_pending and
6213 silc_client_command_pending_del and added new function
6214 silc_client_command_pending_check. Removed the
6215 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6218 * Added cmd_ident, current command identifier, to the client
6219 connection context in lib/silcclient/client.h to keep track on
6220 command identifiers used in command sending. Client's command reply
6221 function handling now supports the mandatory command identifiers.
6223 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6224 funtions in client to fully support pending command callbacks.
6226 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6227 as one of the arguments to the application in the command reply
6230 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6231 before first releasing SILC but came back. Now it is removed again
6232 and should come back nomore. The FORWARDED flag was used only
6233 by the JOINing procedure by forwarding the command packet to router.
6234 Now, the JOINing procedure has been changed to more generic (due
6235 to various router environment issues) and FORWARDED is not needed
6236 anymore for anything. The protocol specification is yet to be
6239 Now, removed silc_server_packet_forward from server and the flag
6240 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6242 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Renamed NAMES command to USERS command. The NAMES was named that
6245 due to historical reasons. Now it is renamed. Also, rewrote
6246 parts of the USERS command. The nickname list is not sent anymore
6247 by the server. Only Client ID and mode lists are sent in the USERS
6248 command. Changed this also to the protocol specification.
6250 The client now resolves the names and stuff after it receives
6251 the USERS list from the server when joining to the channel.
6253 * WHOIS and IDENTIFY commands has been changed to support multiple
6254 Client ID's per command. One can now search for multiple users
6255 in the network by sending only one WHOIS or IDENTIFY command.
6256 Changed the code and the protocol specifications.
6258 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6259 uses silc_server_command_whois_parse to parse the request. */
6261 * If normal server, do not parse the WHOIS and IDENTIFY requests
6262 before sending it to the router. Saves some time.
6264 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Fixed JOIN command on client library. Wrong number of arguments
6267 used to crash the client.
6269 * Added silc_server_channel_has_global function to check whether
6270 channel has global users or not.
6272 * Added silc_server_channel_has_local function to check whether channel
6273 has locally connected clients on the channel.
6275 * The silc_server_remove_from_one_channel now checks whether the
6276 channel has global users or not after given client was removed from
6277 the channel. It also checks whether the channel has local clients
6278 on the channel anymore. If it does not have then the channel entry
6279 is removed as it is not needed anymore.
6281 * The silc_server_notify now checks on JOIN notify whether the joining
6282 client is one of locally connected or global. If it is global then
6283 the channel has now global users on the channel and that is marked
6284 to the channel entry. Also, it now saves the global client to
6285 global list who is joining and JOINs it to the channel. This is
6286 for normal server, that is.
6288 Changed silc_server_send_notify_on_channel,
6289 silc_server_packet_relay_to_channel and
6290 silc_server_packet_send_to_channel check if we are normal server
6291 and client has router set (ie. global client) do not send the
6292 message to that client, as it is already routed to our router.
6294 * Implemented LEAVE notify type handling in silc_server_notify
6297 * Tested LEAVE command in router environment successfully. Tested
6298 with two routers, two servers and two clients.
6302 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6304 * Implemented SIGNOFF notify type handling in silc_server_notify
6307 * silc_server_remove_id now removes the client entry from all channels
6308 it has joined and thusly sends SIGNOFF notify type.
6310 * Rewrote the NAMES list generation in server by removing two excess
6311 loops. The lists are created now inside one loop.
6313 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * silc_server_remove_channel_user checks now also global list
6316 for channel and client.
6318 * silc_server_new_channel_user checks now both local and global
6319 list for channel and client. Fixed a bug in client id decoding.
6320 Used to decode wrong buffer.
6322 * silc_server_channel_message checks now both local and global
6323 list for channel entry.
6325 * Tested channel joining (hence JOIN) in router environment
6326 successfully. Tested with two routers, two servers and two
6329 * Tested channel message sending in router environment successfully.
6331 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Added silc_server_save_channel_key into server.[ch] to save the
6334 received channel key in Channel Key payload processing. It is
6335 also used in JOIN command reply handling.
6337 Equivalent function silc_client_save_channel_key added into
6338 client.[ch] into client library.
6340 * Changed JOIN command reply to send information whether the channel
6341 was created or not (is existing already) and the channel key
6342 payload. Changed protocol specs accordingly.
6344 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6345 the request was sent by ID and not by nickname. Crashed on
6348 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6351 now correctly save the received data.
6353 * silc_server_free_sock_user_data now notifies routers in the
6354 network about entities leaving the network.
6356 At the same time implemented functions silc_server_remove_id
6357 and silc_server_send_remove_id to receive and send REMOVE_ID
6358 packets. The packet is used to notify routers in the network
6359 about leaving entities. The ID removed will become invalid in
6362 * Added function silc_idlist_del_server into server. Removes and
6363 free's server entry from ID list.
6365 * silc_server_private_message function now checks, if we are router,
6366 that the destination ID really is valid ID, naturally.
6368 * In router when NEW_ID packet is received (for new client) the
6369 hash of the Client ID is saved in the ID Cache but the
6370 client->nickname is set to NULL, instead of putting the hash
6373 IDENTIFY command now also checks that client->nickname must be
6374 valid. If it is not if will request the data from the server who
6375 owns the client. Added new function
6376 silc_server_command_identify_check.
6378 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6379 to set the command to already allocated Command Payload.
6381 * Tested private message sending in router environment with two
6382 routers, two servers and two clients. Fixed minor bugs and now
6385 * Fixed segfault from client's NAMES command. Used to crash if
6388 * Forwarded packets must not be routed even if it is not destined
6389 to the receiver. Changed server code comply with this.
6391 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Added `require_reverse_mapping' boolean value to ServerParams
6394 structure. If TRUE (not default) the server will require that
6395 the connecting host has fully qualified domain name.
6397 If the reverse mapping is not required and hostname could not be
6398 found the IP address is used as hostname.
6400 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Implemented version string checking to both client and server.
6403 The check is incomplete currently due to the abnormal version
6404 strings used in development version of SILC.
6406 * Changed all command functions in server to use the new
6409 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Changed char *data to unsigned char *data in ID Cache system to
6412 support binary data as ID Cache data. Changed code to support
6413 binary data in lib/silccore/idcache.c.
6415 * Renamed silc_server_packet_relay_command_reply to
6416 silc_server_command_reply as it is normal packet receiving
6417 function. Rewrote the function to accept command replys for
6418 servers and not only for clients.
6420 * Mark remote router always as registered server if we are connecting
6421 to it. Otherwise, commands sent by the router to us are ignored.
6423 * All ID List find routines now returns the ID Cache Entry pointer
6424 as well if requested.
6426 * WHOIS command works now in router environment, tested with two
6427 routers, two servers and two clients.
6429 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6430 in router environment (as it is almost equivalent to WHOIS) but
6431 hasn't been tested thoroughly. Added new functions:
6433 silc_server_command_identify_parse
6434 silc_server_command_identify_send_reply
6435 silc_server_command_identify_from_client
6436 silc_server_command_identify_from_server
6438 * Disabled route cache adding because adding two different ID's with
6439 same IP replaces the old cache entry thus giving wrong route.
6440 The entry->router->connection is always the fastest route anyway
6441 so route cache may not be needed. Of course, new routes maybe
6442 established after receiving the ID when the entry->router->connection
6443 might not be anymore the most optimal.
6445 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Add route cache for received ID for fast routing.
6449 * Added silc_server_packet_route to route received packet on router
6450 that is not destined to us.
6452 * Renamed silc_server_get_route to silc_server_route_get.
6454 * Added id_string and id_string_len fields into SilcServer to
6455 include encoded ServerID for fast comparing without excess
6456 encoding of the ID's.
6458 * Cleaned up WHOIS command on server side. Added following static
6461 silc_server_command_whois_parse
6462 silc_server_command_whois_check
6463 silc_server_command_whois_send_reply
6464 silc_server_command_whois_from_client
6465 silc_server_command_whois_from_server
6467 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6468 arguments in command replies. All command functions should be
6469 updated to use this macro.
6471 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Minor typo fixes on command reply handling on server.
6475 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Added silc_server_command_add_to_channel internal routine to add
6478 the client to the channel after router has created the channel and
6479 sent command reply to the server.
6481 * Added generic silc_server_send_command to send any command from
6484 * Use static buffer with ID rendering instead of duplicating data.
6486 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Fixed a channel user mode bug when joining to a channel server gave
6489 everybody channel founder rights, oops.
6491 * We mark ourselves as the router of the incoming server connection
6492 if we are router ourselves. This way we can check in some packet
6493 sending functions whether it is locally connected server. For
6494 incoming router connections we put NULL.
6496 * For router sending packets locally means now always sending the
6497 packet cell wide; to local clients and local servers. For normal
6498 server sending packet locally means sending it to only local
6501 * Fixed the JOIN command to really work in router environment. If the
6502 channel is created it is always created by the router. Router is
6503 also responsible of making the initial joining to the channel,
6504 sending JOIN notify to the sending server and distributing
6505 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6506 does not exist server doesn't do anything else but forward the
6507 command to the router which performs everything.
6509 * Added silc_server_send_channel_key function to send the Channel Key
6512 * Added silc_server_create_channel_key to create new channel key. The
6513 channel key is now re-generated everytime someone joins or leaves
6514 a channel, as protocol dictates. Note: channel->key_len is the
6517 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6520 packet_receive.[ch] to separate packet sending and receiving
6521 routines. The server.[ch] now includes everything else including
6522 actual packet processing (writing and reading data) and other
6525 Renamed silc_server_private_message_send_internal to
6526 silc_server_send_private_message. The routine is still though
6527 used only to relay private messages as server does not send
6528 private messages itself.
6530 Renamed silc_server_new_channel to silc_server_create_new_channel
6531 and added new function sicl_server_new_channel that handles the
6532 incoming New Channel packet. Added also new sending function
6533 silc_server_send_new_channel to send New Channel Payload.
6535 * Added new function silc_server_notify to process incoming notify
6536 packet to the server/router. Server may then relay the notify
6537 to clients if needed.
6539 * Added new function silc_server_new_channel_user to process incoming
6540 New Channel User packet. Router will redistribute the packet and
6541 send JOIN notify to its local clients and locally connected servers
6542 if needed. Normal server will send JOIN notify to its local client
6543 on same channel when received this packet. Added also corresponding
6544 sending function silc_server_send_new_channel_user to sent the
6547 * Added boolean route argument to send_notif_to_channel and
6548 packet_send_to_channel functions to attempt to route the packet
6549 if it is TRUE and send only locally if it is FALSE.
6551 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * silc_server_replace_id now broadcasts the received replace ID
6554 packet if it is not broadcast packet already. The router must
6555 broadcast to inform other routers about changed ID.
6557 * Added backpointer to server's router into SilcServer context in
6558 silcd/server_internal.h.
6560 * Fixed silc_server_packet_broadcast to send correct broadcast
6563 * The channel key is now distributed to the local client as soon
6564 as it is received from the router (in router environment) so that
6565 no other packet may be sent for the channel until client has
6568 * silc_server_remove_channel_user now broadcasts the received
6569 Remove Channel User packet if it is not broadcast packet already.
6570 The router must broadcast to inform other routers about removed
6573 * Added users field into SilcPacketContext that is a reference count
6574 of the context. One can increase the reference count by calling
6575 silc_packet_context_dup which is now changed to just increase the
6576 reference count instead of duplicating the data. The reference
6577 count is decresed by calling silc_packet_context_free that will
6578 free the data after the reference count hits zero.
6580 For now on the packet context and everything allocated into it
6581 (including the raw packet from network) must be freed by calling
6582 the new silc_packet_context_free function. Added also new function
6583 silc_packet_context_alloc that must be used now to allocate the
6584 context. This also means that if a routine is asynchronous from
6585 silc_[client/server]_packet_parse_type the packet context must
6586 be duplicated by calling silc_packet_context_dup. Otherwise it
6587 gets free'd after silc_[client/server]_packet_parse_type returns.
6588 Also, one must remember that if packet is duplicated then its
6589 reference count must be decresed by calling the free function as
6590 many times as it was duplicated.
6592 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6593 from both client and server.
6595 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Made joining to a channel working in router environment.
6599 * Cleaned up JOIN command on server side and create function
6600 silc_server_command_join_channel internal routine to make the
6603 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Changed silc_command_pending list to SilcDList. Also, added
6606 `ident' field to SilcServerCommandPending structure to identify
6607 the reply and to call correct callback.
6609 Added silc_server_command_pending_check function to replace the
6610 corresnponding macro. The silc_command_pending list is not
6613 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6614 to set identifier to previously allocated Command Payload. It
6615 is used to set identifier for command when resending Command
6618 * Added silc_command_payload_encode_payload to encode Command
6619 Payload buffer from SilcCommandPayload structure.
6621 * Added silc_argument_payload_encode_payload to encode Argument
6622 payload buffer from SilcArgumentPayload structure.
6624 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Changed WHOIS command to support router connection on server side.
6627 The whois request is always sent to router unless the server is
6628 standalone server. After server has received the reply from the
6629 router will it send the reply to the client.
6631 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6632 broadcast received broadcast packet. The function is used only
6633 by router. The broadcast packet is always sent to the router's
6636 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6637 render given ID to printable string, for log files for example.
6639 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Made basic router to router connections working. At least they
6642 can now connect to each other but nothing really works the way
6643 they are supposed - yet.
6645 * Added new initiator token to RouterConnection configuration
6646 file in silcd/serverconfig.[ch]. It is used to tell whether we
6647 are the initiator to the remote router or whether we'll expect
6648 the other end to connect.
6650 * Moved registering of listener task to silc_server_init, hence
6651 the server starts listenning as soon as it is run, even if it
6652 does not have connections to other routers. Let's see how well
6655 * Changed default connection retry timeouts for more suitable in
6658 * Removed cipher and such arguments from silc_idlist_add_client
6659 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6660 Added new function silc_idlist_add_data to add the keys and stuff
6663 * Added SilcIDListData structure and added it to SilcClientEntry
6664 and SilcServerEntry as their first field in the structure. This
6665 way we can explicitly cast the ID entries to the SilcIDListData
6666 structure and get common data for the entries. In past, we had
6667 to first check what type of connection it is and then cast it to
6668 correct ID entry type. Now, we can directly cast the opaque
6669 pointer to the SilcIDListData (no matter what ID entry it actually
6670 is) and get the data needed.
6672 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6674 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6675 in some circumstances even if threre were timeout tasks, though not
6676 IO tasks, but tasks anyway. Now fixed.
6678 * Defined SilcServerConnection structure to hold connection specific
6679 stuff about directly connected servers and routers. The definition
6680 is currently in silcd/server_internal.h. I thought about having
6681 a bit more important role fro this struct but for now it is used
6682 only when connecting to other server (or router actually).
6684 * Added connecting retry support in server when connecting to
6685 router(s). The retry feature implement exponential backoff
6686 algorithm. Also, added SilcServerParams structure to hold default
6687 parameters for server. For now, it include these retry settings
6688 and are hard coded. After server is moded to be as Silc Server
6689 Library this structure will be more important.
6691 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6693 * Changed client librarys channel->clients table to SilcList and
6694 changed code accordingly.
6696 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6698 * Changed client's channel table to SilcList and changed code
6699 accordingly. Also changed SilcChannelClientEntry to include back-
6700 pointer to the channel so that client entry can use that structure
6701 as list as well and we have fast cross-reference to the channel.
6702 This change dramatically decreased the complexity of channel
6703 handling with client entry and vice versa (removed one extra
6704 loop when searching for channel entry from many functions).
6706 * Changed server->sim from table to SilcDList and changed code
6709 * NAMES command can now be used from user interface. It will show
6710 the user list on the channel, neatly.
6712 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6713 Code now saves realname of the user if it becomes available.
6715 * Renamed configure.in to configure.in.pre and made ./prepare
6716 script to automatically add correct version string to
6717 configure.in which it creates from configure.in.pre.
6719 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * NAMES command reply now shows users mode with the nickname when
6724 * Moved silc_client_ch[u]mode[_char] functions from
6725 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6726 place sucks, they are utility functions and should be in some
6729 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6731 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6734 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Added TRQ (efficient deque and list library) into lib/trq. This is
6739 a very good list library that is currently used in the SILC. Defined
6740 SilcList API over the library because I didn't like the API very
6741 much. See lib/trq/silclist.h for the API and examples of how to
6742 use the API. Fixed various places in the code to use the new
6743 SilcList API. The SilcList is meant for lists that has a structure
6744 already defined as a list. It is not suitable to add just some
6745 context to the list (in TRQ, the context is the list actually).
6747 So, I defined SilcDList that can be used for the purpose where
6748 predefined list structure does not exit. This can be used as
6749 such list. Now some context just can be added to the SilcDList.
6750 Currently this list is not used in the SILC just yet, though there
6751 are a lot places where this can replace dynamically allocated
6752 tables and I will fix these places, later, to use SilcDList.
6753 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6754 and use TRQ internally).
6756 Also fixed some annoying warning messages that the original TRQ
6757 code generated. Also minor changes to TRQ's Makefile.in.
6759 * Added support for querying by Client ID to both WHOIS and
6760 IDENTIFY commands into server, as required by the protocol.
6762 * Removed method function pointers from SilcBuffer structure. They
6763 weren't used to anything and just increased the context size for
6764 no good reason. This change also made silc_buffer_alloc and
6765 silc_buffer_free functions inline functions.
6767 * Disabled command flooding detection support until it's fixed so
6768 that it accepts commands in but does not execute them more than once
6771 * Added silc_net_localhost(), to return local hostname, into
6772 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6773 that must be initialized before calling silc_client_init.
6775 * Added new function: silc_server_send_notify_on_channels to send
6776 notify messages to all channels client has joined. It is assured
6777 that the message is sent only once per client.
6779 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6780 lib/silcutil/silcutil.[ch] as silc_format function. The new
6781 function is generic and is used by server as well, not only by
6782 the logging routines.
6784 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6785 the provided version string was not acceptable. Added new function:
6786 silc_ske_check_version into lib/silcske/silcske.h. The function
6787 must be implemented by the application (client or server) and it
6788 does not reside in the SKE library. The function checks the version
6789 string remote end sent.
6791 * Added back pointers (to opaque context and to SilcSocketConnection)
6792 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6794 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6795 duplicate packet context structure.
6797 * Changed `notify' client operation to send same arguments as client
6798 receives from server except for ID's. ID's are mapped to correct
6799 ID entry and that is returned. Also, if channel entry is not sent
6800 by server but the notify is for channel the channel entry is sent
6801 to application (otherwise application doesn't know that it is for
6802 channel (library gets it from packet's Destination ID)).
6804 * Added silc_client_remove_from_channels into client library to
6805 remove a client from all channels it has joined to. Used when
6806 received SIGNOFF notify from server. Added also new function
6807 silc_client_replace_from_channels to replace old ID entry with
6808 new ID entry on all channels. Used when received NICK_CHANGE
6811 * Fixed ID Cache list handling in silc_idlist_get_client in
6812 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6813 to get (or query) client by ID.
6815 * Updated TODO list.
6817 * Added connection authentication status message defined by the
6818 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6819 support for these into the code in client and server side.
6821 * Added generic function silc_client_send_command to send any command
6822 with variable argument list. Application should use this function
6823 to send commands if the command functions provided by the library
6824 does not suite for the application's user interface needs.
6826 * Added new `failure' client operation. Application is notified about
6827 received failure packet if client is executing a protocol. In this
6828 case the protocol's execution has failed.
6830 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6831 is required by the protocol.
6833 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6834 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6837 * Added status flag to SilcSKE object to indicate realtime status
6838 of the SKE protocol.
6840 * Application receives now exactly same command reply arguments as
6841 the library receives from server. However, if ID is received the
6842 corresponding ID entry is returned to the application (eg. Client
6843 ID is mapped to correct SilcClientEntry entry and that is returned).
6844 Changed command_reply client operation due to this change.
6846 * Changed all ID's in commands and in command replys as ID Payloads.
6847 Change affected both client and server side codes.
6849 All ID's sent in SILC network (with execption of ID's in SILC
6850 Packet header) are sent in ID Payload to support variable length
6853 * Server now notifies nick changes and notifies all clients on
6854 the channels about the new nickname (about the new Client ID,
6857 * Implemented CMODE command to change channel modes. Supports all
6858 channel modes defined by the protocol specs except ban and invite
6859 lists. (Also, private channel key mode is supported but support for
6860 setting private channel key in client is missing, thus, this mode
6861 has no effect on client side (except that server requires that the
6862 client uses private channel key and normal channel traffic does not
6865 Also, invite mode works per se, but INVITE command does not work
6866 yet correctly, so you can set channel as invite only channel but
6867 inviting clients to the channel does not work (it is yet to be
6868 thought what's the best way to do it).
6870 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6871 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6872 Implemented CUMODE command to change user's mode on the channel.
6873 Supports all modes defined by the protocol specs.
6875 * Added NAMES command reply to return users modes on the channel.
6877 * Removed unnecessary and slow ciphers from lib/silccrypt.
6879 * Set SO_KEEPALIVE option to connection sockets by default.
6881 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6883 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6884 redefined the Notify Payload into protocol specs.
6886 * Added silc_id_payload_parse_id to get ID directly from raw
6889 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6892 accept searching by Client ID as well.
6894 * Added support for LEAVE and SIGNOFF notify types in client library.
6896 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6897 to parse ID Payload from raw data.
6899 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Added flags parameter into silc_ske_assemble_security_properties
6902 function in lib/silcske/silcske.[ch].
6904 * Changed notify client operation to fit better for notify messages
6905 sent by server. The notify payload received from server is now
6906 passed to the application (after parsing it to SilcNotifyPayload).
6907 It is application's responsibility to retrieve the arguments
6908 from the payload and show the message the way it wants. The message
6909 sent by server is implementation specific.
6911 * Changed public keys to comply with the protocol specification.
6912 Old public keys are not supported anymore and are not compatible.
6914 * Removed nickname from Channel Payload as the latest draft removed
6915 it. The client must resolve the nickname from the NAMES command
6916 reply received when it joined the channel.
6918 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6920 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6922 * Fixed some errors in protocol specification drafts.
6924 * Created lib/silccore/silcnotify.c to implement Notify Payload
6925 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6926 generic payloads described by protocol specifications. The file
6927 includes implementations for ID Payload and Argument Payload.
6929 * Changed Command Payload implementation to use the new Argument
6930 Payload. Changed command_xxxx_payload to command_payload_xxxx
6931 to comply with SILC coding conventions.
6933 * Added suppport for Argument Payload handling in Notify Payload
6934 implementation as protocol requires it. Added the new support
6935 into server and client lib as well.
6937 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6939 * Added support for multiple nicknames on same channel. [n] is
6940 added locally to the nickname if there are more than one same
6941 nicknames on the channel.
6943 * Server now sends all nicknames that matched WHOIS request.
6944 Client also shows the list received from server.
6946 * Added TOPIC command to client side. User can now set and show
6947 current topic on channel.
6949 * Added MOTD command to client and server. Also, server sends the
6950 motd when client connects to the server.
6952 * Changed version strings to comply ISO 8601.
6954 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6956 * Fixed protocol error handling in client library. It should now
6957 cope even if the SKE fails for some reason.
6959 * Made new protocol specification drafts for submitting to IETF.
6961 * Implemented TOPIC command to server in silcd/command.c.
6963 * Added two new notify types into lib/silccore/silcnotify.h:
6964 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6965 notify nickname change and topic setting/change on a channel.
6967 * API change of command_reply operation in client library. The
6968 application gets now the status type received from server as well.
6970 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6974 * Cras fixed and optimized the packet handling even further and
6975 it should work now. Minor change to the prototype of function
6976 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6978 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Added new function into lib/silcutil/silcschedule.[ch]:
6981 silc_schedule_with_fd to select() a specified fd. The function
6982 returns after timeout expires or data arrives or goes. The
6983 function is used by packet routines to wait that all data is
6984 received from network.
6986 * Fixed data reading from network in lib/silccore/silcpacket.c.
6987 The code now assures that all data is read from the fd and then
6988 continues packet processing. This was a bug fix since the code
6989 used to drop some data in some circumstances.
6991 * Added new function into lib/silcclient/client.[ch]:
6992 silc_client_start_key_exchange to start key exchange after
6993 connection has been established to server. The code internally
6994 now uses this funtion but its main purpose was to provide it
6995 for applications that perform their own connecting. After
6996 application has created a connection it merely calls this
6997 function to start the key exchange between client and server.
6998 The library takes care of everything else after that.
7000 Updated also lib/silcclient/README to explain the usage of
7003 * Do not send to application information that connection has
7004 been established. Application gets notified it by connect
7007 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Applied cras's patch to add silc_schedule_one function. The
7010 function runs scheduler once and returns.
7012 * Fixed the scheduler after cras messed it up. The timeout
7013 handling works now as it's supposed to work.
7015 * Added into lib/silccore/ silcnotify.h to include notify
7016 message types support. Changed silc_server_send_notify*
7017 functions, in server.[ch], to support those new notify types.
7018 Added the support for the notify types into client library,
7019 as well. Added new notify client operation into ops.h in
7022 * Changed silc_server_packet_send_to_channel to send normal
7023 packets instead of just channel message packets. The function
7024 is now used to send the notify packets to channels. It is not
7025 used to send channel message packets anymore, as server never
7028 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7029 va_arg()s as it seems to require it nowadays. I guess, if SILC
7030 is compiled with older va_arg() the new code should work anyway.
7032 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Splitted core library. Core library (lib/silccore) includes
7035 now only SILC protocol specific core (and common) components.
7036 Created new utility library (lib/silcutil) that includes more
7037 generic purpose stuff. The stuff for util library was taken
7038 from the old core library. This was minor and easy split.
7040 * Created SILC Client Library (lib/silcclient) that includes
7041 implementation of the SILC client without user interface. This
7042 was major move from silc/ directory. The code has been changed
7043 so that it is transparent towards the user interface. The
7044 silc/ directory includes now the same user interface as before
7045 and it uses the new client library. Read lib/silcclient/README.
7046 Basicly, the client library performs everything else related
7047 to SILC except user interface handling. Also, configuration
7048 files are considered to be part of user interface and library
7049 does not handle them.
7051 This change also changed a lot of structures, function naming etc.
7052 Most important change was that SilcClientWindow object was
7053 renamed to SilcClientConnection in the client library. Created
7054 also new file lib/silcclient/ops.h. Also added new files
7055 silc/local_command.[ch] and silc/client_ops.[ch].
7057 All these changes were made to make it easier for user interface
7058 designers to create what ever user interface for the SILC client
7061 It is also expected that the server will be moved to lib
7062 directory as well and SILC Server Library will be created;
7063 sometimes in the future.
7065 * Removed Local commands from lib/silccore/silccommand.h as
7066 they are application specific and new client library does not
7067 handle any of those anymore.
7069 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7070 old client implementation in silc/.
7072 * Added support for callback functions in SILC_LOG_* macros.
7073 Application can now set its own callbacks that will be called
7074 instead of using the default functions that will always print
7075 the debug messages to stderr (or stdout). Also, debugging can
7076 now be disabled by setting silc_debug to FALSE and re-enabled by
7077 setting it to TRUE. Note, that logging will still work even
7078 if debugging is disabled.
7080 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7081 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7082 silc_log_reset_debug_callbacks.
7084 * To enable debugging in silc client one must give now -d
7085 option on command line.
7087 * Changed silc_schedule_init to automatically allocate task queues
7088 if they are not allocated before calling it.
7090 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7092 * Added GMP 3.1 into math library.
7094 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7097 a channel in SILC network. The packet is used by servers and
7098 routers to notify other routers that user has left a channel.
7099 This little feature was missing until now. Added the feature
7100 to protocol specification as well.
7102 Added functions: silc_server_send_remove_channel_user and
7103 silc_server_remove_channel_user into server.[ch].
7105 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7106 lib/silccore/silcpacket.h. However, they are not implemented
7109 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Fixed joining to a channel and sending channel messages
7112 between server and router. The channel message sending should
7113 now work inside a cell.
7115 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7117 * Fixed the private message sending between server and router.
7118 The private message sending should now work inside a cell.
7120 * Added silc_server_replace_id into server.[ch] to replace
7121 existing ID in the SILC network.
7123 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7124 and silc_idlist_replace_server_id into idlist.[ch] in server.
7126 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Fixed the server to server connections. Server can again now
7129 connect to router. Router to router connections probably does
7132 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Added dynamic protocol registering support. Now protocols can
7135 registered and unregistered on the fly. Patch by cras.
7137 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Added lib/contrib directory to hold routines that some platforms
7140 don't have but are needed by SILC.
7142 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7143 into lin/contrib to provide getopt() and getopt_long() for
7144 those who don't have it.
7146 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7148 * Added AWAY command to client. When away message is set and
7149 client receives a private message packet the client automatically
7150 replies to the sender with the away message.
7152 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7153 bug seemed to be the cause of recent problems when compiling
7156 * Added version detection support to SKE protocol specification
7157 and added the new changes to the SKE implementation as well.
7158 There were other minor changes in the SKE protocol as well.
7160 Many changes in lib/silcske/silcske.[ch] and in
7161 lib/silcske/payload.[ch].
7163 * Added ^U functionality, clear input line. Patch from cras.
7165 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * Mainly small bugfixes on core library. Fixed some debugging
7168 logging and buffer overflow in silclog.c.
7170 * Updated config.sub and config.guess on the distribution tree.
7172 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7174 * Added command lagging support in server. Client may execute
7175 commands now only once in two seconds.
7177 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Optimized packet reception. MAC computation and checking is now
7180 also more optimized. A lot previously duplicated code is now
7181 used as generic by both client and server.
7183 * Fixed key pair generation in clientutil.c
7185 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Added into lib/silccore/silcbufutil.[ch] new function;
7188 silc_buffer_realloc.
7190 * Moved generic packet sending/encryption functions to
7191 lib/silccore/silcpacket.[ch] from client and server. Some
7192 rewriting of the functions.
7194 * Moved all generic packet reception/decryption functions to
7195 lib/silccore/silcpacket.[ch] from client and server. The
7196 packet processing is now much cleaner in both client and server.
7197 These were major changes in both client and server.
7199 * Created many common functions in server to do packet sending.
7200 Previously code were duplicated a lot, this has been removed
7203 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7205 * Rewrote major parts of the ID cache system. Don't know
7206 whether it is better now or not but at least the API is more
7209 * Major rewrite on ID cache stuff on client because of the ID
7210 cache API changes. Added idlist.c to client.
7212 * Also major rewrite on ID cache stuff on server as well.
7213 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7214 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7215 in hand, instead they are all put into the ID cache system now.
7216 All server_idlist_* routines uses ID cache now instead of
7217 traversing its own lists (those lists does not exist anymore).
7218 SilcIDList though still exists. Also, SilcXXXEntry's are
7221 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Finally made the SKE implementation compliant to the protocol
7224 specification. All mp integers are now binary encoded as
7225 opposed being HEX encoded.
7227 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7230 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7231 functions: silc_[encode/decode]_pem. Also added function
7232 silc_encode_pem_file to PEM encode with newlines ('\n') for
7235 * SILC public keys are now encoded either PEM or binary. Same
7236 option is for private keys as well. By default private keys
7237 are binary encoded and public keys PEM encoded. Silly HEX
7238 encoding were removed.
7240 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7241 function to create fingerprints.
7243 * Fixed a bug in SHA1; does not change the original data anymore.
7245 * Partly implemented INFO command on client and server side.
7246 Fixed CLEAR command. Changes to SERVER command; show current
7247 server(s) when giving command without arguments. Added
7248 VERSION command to client.
7250 * Added check to server that unregistered connections cannot
7251 execute commands (unless it is specificly allowed).
7253 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Fixed screen refresh.
7257 * Fixed channel joining bug from client. On some circumstances
7258 client tried to join to a channel it had already joined.
7260 * Added public key verification process into client's protocol.c.
7261 The client now verifies the public key from user and saves
7262 it into ~./silc/serverkeys/ directory.
7264 Added into: clientutil.[ch]: silc_client_verify_server_key.
7266 * Changed SKE protocol's silc_ske_initiator_finish function
7267 to accept callback function that verifies the received public
7268 key. Removed old silc_ske_verify_public_key function.
7270 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7273 silc_pkcs_private_key[_data]_set.
7275 * Made the password and public authentication more cleaner in
7276 server's protocol.c.
7278 * Removed historic and obsolete protocol `channel_auth' from
7279 both client and server.
7281 * Removed wrong way of sending command status messages from
7282 server to client in server's command.c. The old way violated
7283 protocol specification.
7285 Changes to silccore/silccommand.[ch]: removed
7286 silc_command_encode_status_payload -> not needed anymore,
7287 changed silc_command_encode_payload_va to accept extra
7288 argument on variable argument list. The argument type must
7289 now be provided to the function. Also, added new function:
7290 silc_command_encode_reply_payload_va which is same as
7291 normal command_encode_payload_va except command status type
7292 is provided as extra argument.
7294 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7296 * Added ~./silc directory handling. The directory includes the
7297 public and private keys for the client.
7299 Added silc_client_check_silc_dir, silc_client_create_identifier
7300 and silc_client_load_keys.
7302 * Implemented SILC protocol compliant public key. Added public
7303 and private key saving to and loading from files.
7305 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7306 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7307 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7308 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7309 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7311 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7312 silc_pkcs_load_[public/private]_key.
7314 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Added silc_server_get_route (route.[ch]) to get connection
7317 data for the fastest route for given ID.
7319 * Implemented INVITE command on client and server. The command
7320 were re-defined in the SILC Protocol Specification and the
7321 implementation now complies with the specification.
7323 * Implemented PING command on client and server.
7325 * Implemented NAMES command on client and server. The server side
7326 supports currently only normal server not router server yet.
7327 Some changes to NAMES definition in SILC protocol specification.
7329 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Implemented LEAVE command on client and server.
7333 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7334 again. This change was made to the protocol as well. Server
7335 should not violate the protocol specification anymore.
7337 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7340 was tested. SOCKS4 was not but should work anyway.
