17 hash public keys and compare public keys in hash table. Affected
18 file lib/silcutil/silcutil.[ch].
20 * Added support for specifying multiple public keys for Client
21 connection section in server configuration file. This makes it
22 possible to accept multiple public keys from same host, or to
23 make a section that accepts any incoming host, and have the
24 accepted public keys listed in the section.
26 Added functions silc_sever_[find/get]_public_key, added the
27 support for this actually to all connection sections but only
28 the Client section is currently allowed to specify multiple

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

285 whether given configuration value has been given already.
287 Affected files silcd/serverconfig.[c], server.[c].
289 * Splitted the doc/example_silcd.conf.in. Separated the crypto
290 algorithm parts and created new file silcalgs.conf, that
291 is now included from the example_silcd.conf.in.
293 * Optimized the silc_server_connect_to_router_second to take
294 the connection configuration object from the SilcServerConnection
295 object instead of finding it during the connecting phase.
296 Added the configuration object to SilcServerConnection struct.
297 Affected files silcd/server_internal.h, server.c.

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

381 * Fixed the file transfer's key agreement payload to include
382 zero port also if the hostname is NULL because it could not
385 Call file transfer monitor callback now also if error occurs
386 during key agreement protocol.
388 Changed the silc_client_file_send interface to return the
389 SilcClientFileError instead of session id. The session ID
390 is returned into pointer provided as argument.
392 Check that the file exists locally before sending the
393 file transfer request at all.
395 Affected file lib/silcclient/client_ftp.c, silcapi.h.

407 file lib/silcutil/silclog.c.
409 * Fixed the channel message payload decryption in the function
410 silc_channel_message_payload_decrypt to not modify the original
411 buffer before it is verified that the message decrypted
412 correctly. Otherwise, next time it is called with correct
413 channel key it won't encrypt since the payload is corrupted.
414 Affected file lib/silccore/silcchannel.c.
416 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

459 users list to SilcHashTable. The affected files are
460 lib/silcclient/idlist.[ch].
462 * Fixed a bug in hash table tarversing. While the hash table
463 is traversed with SilcHashTableList the table must not be
464 rehashed. It is now guaranteed that auto rehashable tables
465 are not rehashed while tarversing the list. Also defined that
466 silc_hash_table_rehash must not be called while tarversing
467 the table. Added function silc_hash_table_list_reset that must
468 be called after the tarversing is over. The affected files are
469 lib/silcutil/silchashtable.[ch].
471 * Changed all hash table traversing to call the new
472 silc_hash_table_list_reset in server and in client library.
474 * Added function silc_client_on_channel to return the
475 SilcChannelUser entry if the specified client entry is joined

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

524 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Fixed a crash in server related to channel announcements.
527 Affected file silcd/server.c.
529 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
531 * Fixed memory leaks in silc_server_create_new_channel*
532 functions. Affected file silcd/server.c.
534 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
535 which ID was changed. This way the router will send the
536 user list for the channel again, and server won't be in
537 desync in some rare circumstances. Affected file is
538 silcd/packet_receive.c.
540 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

558 nice file made available.
560 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
562 * Call silc_server_remove_from_channels when removing client
563 entry when NO_SUCH_CLIENT_ID was received. Affected file
564 is silcd/command_reply.c.
566 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
568 * Added server & router operator statistics updating. Affected
569 file silcd/packet_receive.c and silcd/command.c.
571 * Fixed the SERVER_SIGNOFF notify handling on normal server
572 not to save the history information for clients. Same was
573 fixed earlier in remove_clients_by_server function, but not
574 here. Affected file silcd/packet_receive.c.
576 * Raised the default connection-retry count from 4 to 7 in
577 server. Affected file silcd/server.h.
579 * Cancel any possible reconnect timeouts when we start the
580 key exchange. Affected file silcd/server.c.
582 * Do not reconnect on connection failure when SCONNECT was
583 given. Affected files silcd/server.[ch].
585 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
589 * Fixed the NICK command to always give the unformatted
590 nickname to the one giving the NICK command. If unformatted
591 nickname is cached already it will be formatted and the
592 local entry will always get the unformatted nickname.
593 Affected file lib/silcclient/idlist.c.
595 * Fixed some double frees from client library commands.
596 Affected file is lib/silcclient/command.c.
598 * Fixed CUMODE command in server to assure that no one can
599 change founder's mode than the founder itself, there was a
600 little bug. Affected file silcd/command.c.
602 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Removed the SilcClientCommandDestructor from the client
605 libary, it is not needed anymore. Affected files are
606 lib/silcclient/silcapi.h, command[_reply].[ch],
607 client_notify, idlist.c.
609 * Fixed GETKEY command to first resolve client, and then
610 resolve the server only if the client was not found, instead
611 of resolving both at the same time. Affected file is
612 lib/silcclient/command.c.
614 * Added silc_client_start_key_exchange_cb and lookup the
615 remote hostname and IP address before starting the key
616 exchange with server. The affected file is
617 lib/silcclient/client.c.
619 * The server's public key is now saved using the IP address
620 of the server and not the servername for the filename.
621 The hostname public key filename is checked as an fall back
622 method if the IP address based filename is not found.
624 Fixed the GETKEY command to save the fetched server key
627 Print the remote server's hostname now when new key is
628 received during connection process. Affected file is
629 irssi/src/silc/core/client_ops.c.
631 * Return always our own public key to the client if it asks
632 for it with GETKEY command. Affected file silcd/command.c.
634 * Removed the use_auto_addr variable from default config
635 file since it was in wrong section. Affected file is
638 * Fixed TOPIC_CHANGE notification to not route it when it
639 was sent using silc_server_send_notify_to_channel function.
640 Affected file silcd/command.c.
642 * Fixed silc_server_send_notify_kicked to send the kicker's
643 Client ID also, it was missing. Affected files are
644 silcd/command.c, silcd/packet_send.[ch].
646 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
648 * Do not save client history information in SERVER_SIGNOFF.
649 Fixes the bug in normal server that it does not detect
650 the client becoming valid after the server becomes back
651 online. Affected file silcd/server_util.c.
653 * Added `sock_error' field into the SilcSocketConnection
654 context. When error occurs during socket operation (read
655 or write) the error is saved. Added also new function
656 silc_socket_get_error to return human readable socket error
657 message. Affected files are lib/silcutil/silcsockconn.[ch],
658 lib/silcutil/unix/silcunixsockconn.c, and
659 lib/silcutil/win32/silcwin32sockconn.c.
661 * The server now prints the socket error message in the
662 signoff for client. Affected file silcd/server.c.
664 * Fixed the `created' channel information sending from router
665 to server in JOIN command. Checks now whether the channel
666 really was created or not and set it according that.
668 Fixed the JOIN command to use the client entry's current
669 ID during the joining procedure instead of the one it sent
670 in the command (it is checked though), since it can change
671 between the packet processing and command processing, and
672 would just case unnecessary pain in the client end. Affected
673 file silcd/command.c.
675 * Fixed a channel key payload sending to use correct channel
676 ID when the server was forced to change the channel's ID by
677 router. Router sent the key payload with the old Channel ID.
678 Affected file silcd/packet_receive.c.
680 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
682 * Call silc_server_save_channel_key only if the key payload
683 was provided in the JOIN command's command reply. Affected
684 file silcd/command_reply.c.
686 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
688 * Fixed silc_mp_sizeinbase to return the value correctly with
689 MPI. Affected file lib/silcmath/mp_mpi.c.
691 * Fixed the stop_server signal to correctly stop the scheduler
692 and gracefully stop the server when SIGTERM or SIGINT signals
693 are received. Affected file silcd/silcd.c.
695 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
697 * Simple handling of TERM and HUP signals. Also added some log
698 flushing call around. Affected file is
701 * Fixed small bugs in silclog.c. Now buffering output will take
702 effect after 10 seconds since startup: This will ensure that
703 no important startup messages are lost. Also output redirection
704 will preserve original format ([Date] [Type] message).
705 Affected file is lib/silcutil/silclog.c.
707 * Added two options to the config file, in the logging section:
708 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
709 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
711 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Do not print the warning about log files not being initialized
714 more than once to avoid excess logging. Affected file is
715 lib/silcutil/silclog.c.
717 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
718 the SIM copying in make install in Makefile.am.pre.
720 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
722 * Rewritten silclog APIs. Globally interesting changes follows:
723 silc_log_set_files() changed to silc_log_set_file().
724 silc_log_set_callbacks() changed to silc_log_set_callback().
725 ROBOdoc documented silclog header file.
726 SilcLogCb now returns bool to wether inihibit the default
727 handler or not (to keep the old behaviour return always TRUE).
728 The new APIs should also fix the problem of the
729 silcd_error.log file that was written in the current directory.
732 Log files streams will remain opened after silc_log_set_file()
733 call, means less CPU usage notably on high traffic servers.
734 File streams are now full buffered, and flushed to the disk
735 every 5 minutes, lesses HD activity and CPU usage.
736 Messages can be redirected, allowing admins to configure
737 one single logfile for all server messages.
738 the silc_log_quick global variable to activate fast-logging.
739 Affected files lib/silcutil/silclog.[ch]
741 * Changed some code to conform new silclog APIs. Affected
742 files are doc/example_silcd.conf.in, silcd/server.c
743 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
746 * Fixed a memory leak that could occur in some situations.
747 Affected file silcd/serverconfig.c.
749 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
751 * Added the silc_client_del_client to remove the client from
752 all channels as well. Affected file lib/silcclient/idlist.c.
754 * Fixed the client library to correctly remove the client
755 from all channels when the client entry is being destroyed.
756 Affected file lib/silcclient/client_notify.c, command.c.
758 * Added auto-nicking support to the client library. If the
759 applicatio now sets client->nickname it will be sent to the
760 server after connecting by the library. This way for example
761 SILCNICK (or IRCNICK) environment variables will have effect
762 and always change the nickname automatically to whatever
763 it is wanted. Affected file lib/silcclient/client.[ch].
765 * Renamed silc_server_command_bad_chars to the
766 silc_server_name_bad_chars and moved it to the
767 silcd/server_util.[ch]. Added also new function
768 silc_server_name_modify_bad to return nickname that
769 includes bad characters as new nickname without those
770 bad characters. This check and modify is now used in
771 silc_server_new_client when the username is initially set
772 as nickname, so it must be checked to be valid nickname.
773 Affected file silcd/packet_receive.c.
775 * The nickname length is now taken from the packet for real
776 and not trusted to strlen() since it clearly can return
777 wrong length for nickname including bad characters. This
778 also applies to channel names. Affected file silcd/command.c.
780 * Removed the lib/silcsilm/modules directory. Modules are now
781 compiled into the lib/silcsim. Fixed the copying of the
782 modules to follow symbolic links in Makefile.am.pre.
784 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
786 * Fixed silc_string_regexify list creation. Fixes bugs with
787 BAN and INVITE commands in server. The affected file is
788 lib/silcutil/unix/silcunixutil.c.
790 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
792 * Removed the command destructor entirely from the server's
793 command and command reply routines. It is not needed, and
794 its usage was buggy and caused crashes. Affected files are
795 silcd/command[_reply].[ch].
797 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
799 * Cancel protocol and NULL sock->protocol if timeout
800 occurred during protocol. Affected file silcd/server.c.
802 * Cancel protocol timeouts always before calling the final
803 callback, to assure that after final callback is called
804 no other state will be called for the protocol anymore.
805 Affected file silcd/protocol.c.
807 * Print error log if incoming connection configuration could
808 not be found. Affected file silcd/server.c.
810 * Fixed JOIN command to correctly save the founder mode
811 to the client on normal SILC server, when the channel
812 was created by the router. Affected file silcd/command.c.
814 * Fixed LIST command (hopefully) to send correct reply
815 packets. Affected file silcd/command.c.
817 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
819 * The silc_packet_receive_process now returns FALSE if the
820 read data was invalid packet, and TRUE if it was ok.
822 The server now checks that if unauthenticated connection
823 sends data and its processing fails the server will close
824 the connection since it could be a malicious flooder.
826 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
828 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
830 * Make sure the warning about error opening a log file is
831 printed only once and not everytime it fails (produces
832 too much useless log). Affected file lib/silcutil/silclog.c.
834 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
836 * Made the silc_server_daemonise() function more readable.
837 Affected file silcd/server.c.
839 * Pid file is now optional, the user may comment it out from
840 the config file. Removed define SILC_SERVER_PID_FILE, we
841 don't need a default any longer. Affected file
842 configure.in.pre, lib/Makefile.am.pre.
844 * Make some use of the pid file. The server now dies at startup
845 if it detects a valid pid file on his path. The server would
846 die anyway in this circumstance, because of the bind() failure.
847 Affected file silcd/silcd.c.
849 * No longer compiling lib/dotconf.
851 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Fixed JOIN command parsing not to crash. Affected file
854 lib/silcclient/command.c.
856 * Fied the NICK_CHANGE notify to add the new client entry
857 even it is resolved. This removes an <[unknown]> nick
858 thingy bug in the client. Affected file is
859 lib/silcclient/client_notify.c.
861 * Do not try to allocate 0 bytes (efence does not like it)
862 in lib/silccore/silccomand.c when encoding payload.
864 * Do not take IRCNICK as nickname in Irssi SILC client since
865 it is not possible to set nickname before hand connecting
866 the server (TODO has an entry about adding auto-nicking
869 * Changed the silc_server_command_pending to check whether
870 there already exists an pending entry with the specified
871 command, command identifier and pending callback. This is
872 to fix IDENTIFY and WHOIS related crashes that may register
873 multiple pending commands with same identifier. Affected
874 file silcd/command.c.
876 * Fixed the server to reconnect to the router even if it
877 was already reconnecting and EOF was received. This to
878 fix a possibility that the server wouldn't ever try to
879 auto-reconnect to the router. Affected file silcd/server.c.
881 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Fixed the server's password authentication to use the
884 length of the locally saved password, and not the one
885 sent in the packet. Affected file silcd/protocol.c.
887 * Fixed same password authentication problem in the
888 Authentication Payload handling routines in
889 lib/silccore/silcauth.c.
891 * Yet another password authentication problem fixed with
892 channel password handling in silcd/command.c.
894 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
896 * If first character of string in silc_parse_userfqdn is '@'
897 then do not parse it. Affected file is
898 lib/silcutil/silcutil.c.
900 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
902 * Fixed minor bug in IDENTIFY command reply sending, which
903 caused various weird problems during JOIN when it was
904 resolving names for users. Affected file silcd/command.c.
906 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
908 * Fixed the IDENTIFY command reply sending to chech better valid
909 clients. It was possible to send incomplete list of replies.
910 Affected file silcd/command.c.
912 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Added silc_client_command[s]_[un]register functions now to
915 dynamically register the commands in client library. Removed
916 the static table of commands. This allows the client library
917 to call commands without causing the application to know about
918 what commands library has called.
920 Removed the INFO command reply kludge to detect when the command
921 was called by library. Now library use its own command reply
922 function for INFO command.
924 Added function silc_client_command_call to call a command.
925 Application can use it to call command, not access the structure
928 Now all commands that are sent by the client library (not
929 explicitly sent by application) use own command reply functions.
931 Affected files around lib/silcclient/ and in
932 irssi/src/silc/core/.
934 * Fixed the WHOIS command reply sending to chech better valid
935 clients. It was possible to send incomplete list of replies.
937 Fixed the WHOIS and IDENTIFY to send the request to router
938 if normal server did not do it and did not find any results.
940 Affected file silcd/command.c.
942 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
944 * Moved the internal data from SilcClient context into its
945 own file, not accesible to application. Affected files
946 lib/silcclient/client.h and lib/silcclient/client_internal.h,
947 and other files in client library.
949 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
951 * Added doc/examples installation target in Makefile.am.pre.
954 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
956 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
957 commands the found client entry will be removed from the
958 cache, after notifying application about the error. Affected
959 file lib/silcclient/command_reply.c.
961 * Changed the /MSG to check for exact nickname user gave, and
962 not let `nick' match `nick@host' if it is only one found. Now,
963 user must type the exact nickname (like nick@host2) even if
964 there are no more than one same nicks found. This is to avoid
965 a possibility of sending nickname to wrong nickname since
966 `nick' could match `nick@host'. Affected file is
967 irssi/src/core/silc-servers.c.
969 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Do not print "you are now server operator" or similar when
972 giving /away command. Affected files are
973 irssi/src/silc/core/client_ops.c, silc-servers.h.
975 * Made the silc_server_command_pending_error_check to send
976 the same command reply payload it received back to the
977 original sender of the command. This way all arguments
978 that was received by the server will be received by the
979 client too. Affected file silcd/command.c.
981 * Added the silc_idcache_add to return the created cache entry
982 to a pointer. Affected file lib/silccore/silcidcache.[ch].
984 * Add global clients to expire if they are not on any channel.
985 This is because normal server will never know if they signoff
986 if they are not on any channel. The cache expiry will take
987 case of these entries. This is done by normal servers only.
988 The affected files are silcd/command_reply.c,
989 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
991 * If server receives invalid ID notification for WHOIS or
992 IDENTIFY and the ID exists in the lists, it is removed.
993 Affected file silcd/command_reply.c.
995 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
996 in client then client entry that it matches is searched and
997 the nickname is printed on the screen for user. Affected
998 file irssi/src/silc/core/client_ops.c.
1000 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Use cache entry expire time in the LIST command reply to
1003 purge old entries from the cache after the LIST command
1004 reply has been received. This way we don't have non-existent
1005 entries in the cache for too long. Affected file is
1006 silcd/command_reply.c.
1008 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1010 * If we are normal server, and we've not resolved client info
1011 in WHOIS or IDENTIFY from router, and it is global client,
1012 we'll check whether it is on some channel. If it is not
1013 then we cannot be sure about its validity and will resolve it
1014 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1015 file silcd/command.c.
1017 * Search channel by name (if possible) rather than by ID
1018 in IDENTIFY command's command reply. Affected file is
1019 silcd/command_reply.c.
1021 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1024 Updated specs and implemented it. Affected file silcd/command.c,
1025 silcd/packet_send.c and silcd/packet_receive.c.
1027 * Implemented the <founder auth> payload handling in the JOIN
1028 command. If provided all conditions for channel joining
1029 except requirement to provide correct passphrase can be
1030 overrided by the channel founder. Updated the protocol specs.
1031 Affected file silcd/command.c.
1033 Added support for founder auth in JOIN command in client
1034 library. Fixed the parsing of the JOIN command now to support
1035 all options as they should be. The affected file is
1036 lib/silcclient/command.c.
1038 * Optimized the WHOIS and IDENTIFY commands to send the request
1039 to router only if it includes nicknames or other names. If
1040 they include only IDs then check the local cache first before
1041 routing. Affected file is silcd/command.c.
1043 * Added channels topic announcements. Affected file is
1044 silcd/packet_receive.c and silcd/server.c.
1046 * Fixed the silc_server_send_notify_topic_set to really destine
1047 the packet to channel. Affected file silcd/packet_send.c.
1049 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1050 library. Affected file lib/silcclient/client_notify.c.
1052 * Added UMODE announcements. Affected file silcd/server.c.
1054 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Memory leak fixes in:
1058 lib/silcutil/silcsockconn.c
1059 lib/silcske/silcske.c
1060 lib/silcske/groups.c
1062 lib/silccrypt/silcpkcs.c
1063 lib/silccore/silccommand.c
1064 lib/silccore/silcidcache.c
1069 * ROBOdoc documented the lib/silcske/groups.h file and a
1070 bit changed the interface for better.
1072 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1074 * Update the client entry context in the ID cache after
1075 nick change. Affected file lib/silcclient/command.c.
1076 Fixes the CUMODE command when regaining founder privileges,
1077 and a little WHOIS problem.
1079 * Fixed silc_net_gethostbyname to correctly call the
1080 inet_ntop. Affected file lib/silcutil/silcnet.c.
1082 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1084 * Added IPv6 support checking to the configure.in.pre, added
1085 also --enable-ipv6 option to override the check. Affected
1086 file configure.in.pre.
1088 * The silc_thread_create now calls the start function
1089 directly if threads support is not compiled in. Removes
1090 ugly #ifdef's from generic code. Affected files are
1091 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1093 * Added silc_net_gethostby[name/addr]_async to asynchronously
1094 resolve. Affected files are lib/silcutil/silcnet.[ch].
1096 * Added support for rendering IPv6 based server, client and
1097 channel IDs. Affected file lib/silcutil/silcutil.c.
1099 * Added support for creating IPv6 based server IDs. Affected
1100 file is silcd/serverid.c.
1102 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1104 * Added silc_net_gethostby[addr/name] into the
1105 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1106 routines. Added silc_net_is_ip[4/6]. Affected file is
1107 lib/silcutil/unix/silcunixnet.c. All routines that take
1108 address as argument now supports both IPv4 and IPv6 addresses.
1110 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1112 * Fixed LIST command reply sending in server. Affected file
1115 * Server now sends the kicker's client ID in the KICK notify
1116 to the kicked client. Affected file silcd/command.c.
1118 * The client library now parses the kickers client ID and
1119 UI displays it. Affected files lib/silcclient/client_notify.c
1120 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1122 * Made all payload parsing function prototypes consistent.
1123 They all take now const unsigned char * and uint32 pair as
1124 the payload data instead of SilcBuffer. Changes all around
1125 the source tree. Other unsigned char* -> const unsigned char*
1126 changes around the tree as well.
1128 * Optimized SFTP client and server packet sending not to
1129 allocate new buffer for each packet but to recycle the
1130 first allocated buffer. Affected files are
1131 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1133 * Optimized the SFTP client to use SilcList instead of
1134 SilcDList for requests, because it is faster. Affected file
1135 is lib/silcsftp/sftp_client.c.
1137 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1138 into lib/silccore/silcid.[ch].
1140 Renamed silcpayload.[ch] into silcargument.[ch].
1142 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1144 * If client entry is deleted with active key agreement
1145 session, abort the session.
1147 The silc_client_abort_key_agreement now calls the completion
1148 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1150 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1153 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Don't use __restrict in older GCC's. Affected file is
1156 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1158 * silc_net_localhost now attempts to reverse lookup the
1159 IP/hostname. Affected file lib/silcutil/silcnet.c.
1161 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1162 command. It can be used to gain founder privileges at
1163 the same time when joining the channel.
1165 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1166 kicker's client ID as well. Updated protocol specs.
1168 Defined that the server must send SILC_COMMAND_IDENTIFY
1169 command reply with error status to client who sent
1170 private message with invalid client ID.
1172 Updated the protocol specification.
1174 * Added silc_server_send_command_reply to send any
1175 command reply. Affected file silcd/packet_send.[ch].
1177 * Added silc_id_payload_encode_data to encode ID payload
1178 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1180 * The server now send IDENTIFY command reply with error
1181 status if client ID in private message is invalid. Affected
1182 file silcd/packet_receive.c.
1184 * Save the server key file with server's IP address in
1185 the filename instead of hostname. The affected file is
1186 irssi/src/silc/core/client_ops.c.
1188 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1193 * Added libtool support for compiling shared objects in
1194 lib/silcsim. Affected file configure.in.pre and
1195 lib/silcsim/Makefile.am. Original patch by cras.
1197 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Pid file configuration, and server's config file fixes
1200 patch by toma. Updated CREDITS file.
1202 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Fixed silc_client_channel_message to not try to decrypt
1205 the message twice if it resolved the destination client
1206 information. This could cause of dropping one channel
1207 message. Affected file lib/silcclient/client_channel.c.
1209 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1211 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1212 lib/silcclient/client.c. This function is used when the SILC
1213 Client is run under some other scheduler, or event loop or
1214 main loop. On GUI applications, for example this may be
1215 desired to used to run the client under the GUI application's
1216 main loop. Typically the GUI application would register an
1217 idle task that calls this function multiple times in a second
1218 to quickly process the SILC specific data.
1220 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1222 * Fixed silc_server_drop() for dropping the supplementary
1223 groups as well, this could cause a security hole on some
1226 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1231 * Write PID file after dropping privileges. Added -F option
1232 to run server on foreground. A patch by debolaz.
1233 Affected files silcd/server.c, silcd/silcd.c.
1235 * Fixed MOTD to return the MOTD file server name. Affected
1236 file silcd/command.c.
1238 * Added INFO command reply handling to the Irssi SILC Client.
1239 Affected file irssi/src/silc/core/client_ops.c.
1241 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1243 * Fixed the silc_idcache_list_* routines to really support
1244 the dynamic list. Fixes a crash. Affected file is
1245 lib/silccore/silcidcache.c.
1247 * Fixed the LIST command reply to really call LIST command's
1248 pending callbacks. Affected file silcd/command_reply.c.
1250 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Update conn->local_entry->nickname after giving NICK
1253 command. Affected file lib/silcclient/command.c.
1255 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1257 * Added the [pid] option to the silcd configuration file
1259 Affected files: serverconfig.[ch] and silcd.c
1261 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Save fingerprint in WHOIS command reply in server.
1264 Affected file silcd/command_reply.c.
1266 * Fixed NICK commands pending callback registration.
1267 Affected file lib/silcclient/command.c.
1269 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1271 * Use ++server->cmd_ident when sending commands in server,
1272 instead of random number. Affected file silcd/command.c.
1274 * Fixed GETKEY command reply to call actually GETKEY pending
1275 command callbacks. Affected file silcd/command_reply.c.
1277 * A bit stricter check for nicknames. Check for same nickname
1278 in NICK command also. Affected file silcd/command.c.
1280 * Do not call INFO command everytime client ID changes, only
1281 during first connecting. Affected file lib/silcclient/client.c.
1283 * Set the new nickname only after successful command reply for
1284 NICK command is returned by server. Affected file
1285 lib/silcclient/command.c.
1287 * Remove nicknames from nicklist during server_signoff notify.
1288 Should fix /NAMES bit more. The affected file is
1289 irssi/src/silc/core/silc-channels.c.
1291 * Added `fingerprint' field to the SilcIDListData in the
1292 silcd/idlist.h to hold the fingerprint of the client's
1295 Send the fingerprint of the client's public key in WHOIS
1298 Affected files silcd/command.c, and silcd/idlist.[ch].
1300 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1301 create fingerprint from given data.
1303 * Show the fingerprint of the client's public key in WHOIS.
1304 Affected files irssi/src/module-formats.[ch] and
1305 irssi/src/silc/core/client_ops.c.
1307 * Format the multiple same nicknames also during JOIN and
1308 NICK_CHANGE notifys. Affected file is
1309 lib/silcclient/client_notify.c.
1311 * Do not print error on screen for invalid private message
1312 payload since it can come if someone is sending private
1313 messages with wrong key. Affected file
1314 lib/silccore/silcprivate.c.
1316 * Fixed multiple concurrent /PING crash. Affected file
1317 lib/silcclient/command.c.
1319 * Changed the wrong ID encoding. All IP addresses must be
1320 in MSB first order in encoded format. They were encoded
1321 wrong and was in LSB format. Affected files are
1322 silcd/serverid.c, lib/silcutil/silcutil.c.
1324 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1326 * Call the `connect' client operation through the scheduler
1327 in case of error. Affected file lib/silcclient/client.c.
1329 * Call the `failure' client operation even if the error
1330 occurred locally during a protocol. Affected file is
1331 lib/silcclient/protocol.c.
1333 * Added support of sending LIST command to router from normal
1334 server. This way normal server can get list of all channels
1335 in the network too. Fixed the channel list sending in the
1336 server too. Affected files are silcd/command.c, and
1337 silcd/command_reply.[ch].
1339 * Added silc_server_update_channels_by_server and
1340 silc_server_remove_channels_by_server. They are used during
1341 disconnection of primary router and in backup router protocol.
1342 Affected file silcd/server_util.[ch], silcd/server.c and
1343 silcd/server_backup.c.
1345 * Fixed channel adding to global list in IDENTIFY command
1346 reply in server. Affected file silcd/command_reply.c.
1348 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * If the incoming packet type is REKEY or REKEY_DONE process
1351 that packet always synchronously. Fixes yet another MAC
1352 failed error on slow (dialup) connections. Affected file
1353 lib/silcclient/client.c and silcd/server.c.
1355 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1357 * Call check_version SKE callback for initiator too. Affected
1358 file lib/silcske/silcske.c.
1360 * Implemented fix for security hole found in the SKE that was
1361 fixed in the specification few days back; the initiator's
1362 public key is now added to the HASH value computation.
1363 Added backwards support for the old way of doing it too, for
1364 old clients and old servers. Affected file is
1365 lib/silcske/silcske.c.
1367 * Enabled mutual authentication by default in SKE. If initiator
1368 is not providing mutual authentication the responder will
1369 force it. This will provide the proof of posession of the
1370 private key for responder. The affected files are
1371 lib/silcclient/protocol.c and silcd/protocol.c.
1373 * Do not cache anymore the server's public key during SKE.
1374 We do mutual authentication so the proof of posession of
1375 private key is done, and if the server is authenticated in
1376 conn auth protocol with public key we must have the public
1377 key already. Affected file silcd/protocol.c.
1379 * Added new global debug variable: silc_debug_hexdump. If
1380 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1381 file lib/silcutil/silclog.[ch].
1383 * Fixed compilation warning due to char * -> const char *.
1384 Affected files lib/silcutil/silcnet.h, and
1385 lib/silccore/silcauth.[ch].
1387 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1389 * Fixed CMODE command when new channel key was created. If
1390 the creation failed the old key was removed. Next time giving
1391 same command would crash the server since the old key was
1392 freed already. Affected file silcd/command.c.
1394 * Fixed the silc_server_announce_get_channels to not crash
1395 on reconnect. Affected file silcd/server.c.
1397 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Added silc_log_set_debug_string function to set a regex
1400 string to match for debug output. Only the function names,
1401 or filenames matching the given debug string is actually
1402 printed. This way it is possible to filter out those debug
1403 strings that user is not interested in.
1405 Fixed a bug in silc_string_regexify.
1407 Affected files lib/silcutil/silclog.[ch], and
1408 lib/silcutil/unix/silcunixutil.c.
1410 * Changed the -d options in both server and Irssi SILC client
1411 to take the debug string as argument. Affected files
1412 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1414 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Added silc_hash_babbleprint to create a Bubble Babble
1417 Encoded fingerprint. The encoding is developed by Antti
1418 Huima (draft-huima-babble-01.txt), and it creates human
1419 readable strings out of binary data. Affected file
1420 lib/silccrypt/silchash.[ch].
1422 * Print the babble print now in addition of fingerprint as well
1423 in Irssi SILC client. Affected files are
1424 irssi/src/fe-common/silc/module-formats.[ch],
1425 irssi/src/fe-common/silc/core/client_ops.c.
1427 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Fixed a security problem found in SKE. The initiator's
1430 public key too is now added to the HASH hash value creation
1431 which is signed by the responder to create the SIGN value.
1432 This will prevent anyone in the middle to lie to the responder
1433 about the initiator's public key. If this is done now, the
1434 man in the middle will get caught. Updated the protocol
1437 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Better installation directory handling. Configure module
1440 paths and other paths automatically to example_silc* files
1441 in doc/. A patch by toma.
1443 * Fixed compiler warning from MPI library, and from SILC RNG.
1446 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1447 It can be configured with ./configure. A patch by toma.
1449 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Find correct make to use in prepare-clean. A patch by
1452 toma. Affected file prepare-clean.
1454 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1456 * Added irssi variables use_auto_addr, auto_bind_ip,
1457 auto_bind_port and auto_public_ip.
1459 * Changed the interface for silc_client_send_key_agreement
1460 in lib/silcclient/silcapi.h
1464 irssi/src/silc/core/silc-core.c
1466 lib/silcclient/silcapi.h
1467 irssi/src/silc/core/silc-channels.c
1468 lib/silcclient/client_keyagr.c
1471 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Added silc_pkcs_public_key_compare to compare two
1474 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1476 * Check that the client who set the founder mode on the
1477 channel is the same client that is giving the founder
1478 mode to itself. It is done by comparing the saved public
1479 key (it is saved even in the authentication is passphrase).
1480 Affected file silcd/command.c.
1482 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Do not process packet for disconnected socket connection.
1485 Affected file lib/silccore/silcpacket.c.
1487 * Process the DISCONNECT packet through scheduler in the
1488 client library. Affected file lib/silcclient/client.c.
1490 * Fixed the silc_client_packet_parse to not to increase
1491 the packet sequence number if the conn->sock and the
1492 current socket connection is not same. This can happen
1493 for example during key agreement when the conn includes
1494 multiple socket connections (listeners). Affected file
1495 lib/silcclient/client.c.
1497 * The sender of the file transfer request now provides also
1498 the pointer (listener) for the key exchange protocol. If
1499 the listener cannot be created then it sends empty key
1500 agreement and lets the receiver provide the listener.
1502 Added `local_ip' and `local_port' arguments to the
1503 silc_client_file_send. If they are provided they are used,
1504 if not then it will attempt to find local IP address, if
1505 not found or bind fails then the remote client will provide
1508 Affected files are lib/silcclient/client_ftp.c and
1509 lib/silcclient/silcapi.h.
1511 * Extended the FILE SEND command to support defining the
1512 local IP and port for key exchange listener. They are
1513 optional. Affected file irssi/src/silc/core/silc-servers.c.
1515 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Defined to WHOIS command reply the sending of fingerprint
1518 of the client's public key (if the proof of posession of the
1519 corresponding private key is verified by the server).
1520 Updated to the protocol specification.
1522 * Added support of receiving the client's public key's
1523 fingerprint in command reply in client library. Affected
1524 file is lib/silcclient/command_reply.c, and
1525 lib/silcclient/idlist.[ch].
1527 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1529 * Do not send over 128 chars long nickname to the server
1530 in NICK command. Affected file lib/silcclient/command.c.
1532 * Do not send over 256 chars long channel names to the server
1533 in JOIN command. Affected file lib/silcclient/command.c.
1535 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Assure that silc_server_close_connection cannot be called
1538 twice for same socket context. Affected file is
1541 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Send error message to application if opening file for
1544 writing during file transfer fails. Affected file is
1545 lib/silcclient/client_ftp.c.
1547 Remove all file transfer sessions for a client that we're
1548 removing from ID cache.
1550 Affected file is lib/silcclient/client_ftp.c.
1552 * Fixed silc_net_addr2bin to return correct address. Affected
1553 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1555 * Fixed file transfer session removing on signoff notify.
1556 Affected file irssi/src/silc/core/silc-servers.c.
1558 * Added the SilcClientFileError to be returned in the monitor
1559 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1560 Affected file lib/silcclient/silcapi.h.
1562 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Fixed a crash in silc_client_ftp_free_sessions and
1565 silc_client_ftp_session_free_client. Affected file
1566 lib/silcclient/client_ftp.c.
1568 * Added `disabled' field in the SilcChannelEntry in the server
1569 to indicate if the server entry is disabled. Affected file
1570 silcd/idlist.h, silcd/command[_reply].c.
1572 * SILC server adds now /var/run/silcd.pid everytime it is
1573 started. Affected file silcd/silcd.c.
1575 * Added silc_server_packet_send_clients to send a packet to
1576 the provided table of client entries. Affected file
1577 silcd/packet_send.[ch].
1579 * Fixed a crash in client resolving in client_prvmsg.c in
1580 client library. Affected file lib/silcclient/client_prvmsg.c.
1582 * Do not actually remove the client directly from ID cache
1583 during SERVER_SIGNOFF, but invalidate it. This way we
1584 preserve the WHOWAS info for the client. Affected file
1585 silcd/server_util.c.
1587 * Fixed SERVER_SIGNOFF notify handling in the server. The
1588 server is now able to process incoming SERVER_SIGNOFF notify
1589 for a server that it doesn't even know about. It will remove
1590 the clients provided in the notify. Affected file
1591 silcd/packet_receive.c.
1593 * Check for partial packet in data queue after every packet that
1594 was found from the queue. Return and wait for more data if
1595 there is partial data in queue. Affected file is
1596 lib/silccore/silcpacket.c.
1598 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Added SilcClietFileError enum to indicate error in
1601 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1602 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1603 Affected files lib/silcclient/silcapi.h and
1604 lib/silcclient/client_ftp.c.
1606 * Check that newsize in silc_buffer_realloc is larger than
1607 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1609 * Added better monitor of file transfers. It now monitors
1610 key agreement protocol during the file transfer too. Added
1611 error reporting too. Affected files
1612 irssi/src/silc/core/silc-servers.c,
1613 irssi/src/fe-common/silc/module-formats.[ch].
1615 * Wrote a help file for FILE command.
1617 * Added silc_rng_global_get_byte_fast to get not-so-secure
1618 random data as fast as possible. Random data is read from
1619 /dev/urandom if available and from the SILC RNG if not
1620 available. It is used in padding generation. Affected file
1621 lib/silccrypt/silcrng.[ch].
1623 * All packets in client library are now processed synchronously.
1624 Optimized packet processing a lot. Affected file
1625 lib/silcclient/client.c.
1627 * All server connection packets are processing synchronously
1628 now in server, to optimize packet processing. Affected file
1631 * Include files are installed now only in Toolkit distribution
1632 if make install is given. Affected files: all Makefile.am's.
1634 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1636 * Assure that silc_client_notify_by_server_resolve does not
1637 resolve the client information multiple times. If it cannot
1638 be found by the first it cannot be found at all. Affected
1639 file lib/silcclient/client_notify.c.
1641 * Fixed WHOWAS command reply calling. Affected file
1642 lib/silcclient/command_reply.c.
1644 * Removed all references to silc_idlist_get_client from the
1645 Irssi SILC client since that call is internal call used by
1646 the library. The Irssi SILC client will use now client
1647 retrieval functions found in silcapi.h.
1649 * Fixed a bug in resolving nickname info before sending
1650 private message. It used freed memory. Affected file
1651 irssi/src/silc/core/silc-servers.c.

1672 * Added silc_net_localip to return local host's IP address.
1673 Affected file lib/silcutil/silcnet.[ch].
1675 * If key exchange or rekey protocol is active for a connection
1676 parse all packets syncronously since there might be packets
1677 in packet queue that we are not able to process without first
1678 processing packets before them. Affected file silcd/server,
1679 lib/silcclient/client.c.
1681 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1682 whether library should continue processing the packet.
1683 Affected file lib/silccore/silcpacket.h.

1729 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1730 is incomplete and is being resolved, it won't be resolved
1733 Make sure also that USERS command reply does not resolve
1734 twice information. Affected file is
1735 lib/silcclient/command_reply.c.
1737 Make sure that silc_client_get_clients_by_list does not
1738 resolve twice same information.
1740 * Check for valid client->id in the silc_server_free_client_data.
1741 Affected file silcd/server.c.
1743 * Fixed /GETKEY nick@server not to crash if the server entry
1744 is not found. Affected file lib/silcclient/command.c.
1746 * Fixed the silc_server_check_cmode_rights to check the
1747 requested modes correctly. Affected file silcd/command.c.

1751 * Better checks for non-printable chars in nick added.
1752 Affected file silcd/command.c.
1754 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Call the silc_server_udpate_servers_by_server in the
1757 primary router that comes back online in the backup resuming
1758 protocol. Otherwise it routes packets wrong. Affected file
1759 silcd/server_util.[ch], silcd/server_backup.c.
1761 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1764 lib/silcutil/silcbuffmt.[ch].
1766 * Redefined the SILC packet header to include the padding
1767 length. Affected file lib/silccore/silcpacket.[ch].
1769 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1770 length for maximum padding up to 128 bytes). Affected
1771 file lib/silccore/silcpacket.h.
1773 * Removed all backwards support for old 0.5.x MAC thingies.
1774 The SILC packet header change makes it impossible to be
1775 backwards compatible.
1777 * Send the ENDING packet with timeout in the backup resuming
1778 protocol. This is to assure that all routers has connected
1779 to the primary router. Affected file silcd/server_backup.c.
1781 * Changed the RNG to take the first IV from random data. It
1782 used to take it from zero actually. Changed the RNG also
1783 to use /dev/urandom during session. /dev/random is used
1784 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1786 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Changed the SILC packet header to have the first two bytes
1789 (the packet length) encrypted. Affected files aroung the
1790 code tree, lib/silccore/silcpacket.[ch]. Removed the
1791 SilcPacketCheckDecrypt callback. It is not needed anymore
1792 since the silc_packet_receive_process will determine now
1793 whether the packet is normal or special.
1795 * Implemented the unidirectional MAC keys. Affected files
1796 lib/silcske/silcske.c, silcd/protocol.c and
1797 lib/silcclient/protocol.c.
1799 * Implemented the packet sequence number to the MAC computation.
1800 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1801 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1802 lib/silcclient/protocol.c.
1804 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Allow backup router to announce servers. All servers
1807 announced by backup router are added to the global list
1808 automatically. Update hte server's socket to our primary
1809 router also when backup router announces a server.
1810 Affected file silcd/packet_receive.c.
1812 * Do not update the client->router in the function
1813 silc_server_udpate_clients_by_server if the client is on
1814 global list. We might fail to find any specific server
1815 for locally connected clients and local cell clients. They
1816 should still use the `from' and not `to' as client->router.
1817 This fixes backup router resuming protocol. Affected file
1818 silcd/server_util.c.
1820 * Decrease channel statistics count only if the channel
1821 deletion worked. Affected files are silcd/server.c and
1822 silcd/server_util.c.
1824 * Added silc_server_update_servers_by_server to update origin
1825 of all server entries. Used during backup router protocol.
1826 Affected files silcd/server_util.[ch], silcd/server.c. and
1827 silcd/backup_router.c.
1829 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1830 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1831 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1832 lib/silccrypt/silchmac.c.
1834 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Assure that router cannot reroute the same channel message
1837 to the sender. Affected file silcd/packet_receive.c.
1839 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Made better checks that the channel message is not sent
1842 to the router it came from. Affected file is
1843 silcd/packet_send.c. Fixed memory leak too.
1845 * Announce informations for incoming router connection, but
1846 only after checking if it is replaced by backup router.
1847 Affected file silcd/packet_receive.c.
1849 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Fixed the backup resuming protocol to work in multiple
1852 router environment. Affected file silcd/server_backup.c.
1854 * Route packet only to one router in the function
1855 silc_server_packet_send_to_channel. Affected file is
1856 silcd/packet_send.c.
1858 * Fixed silc_server_send_notify_dest to set the broadcast
1859 flag. Fixed the silc_server_send_notify_topic to actually
1860 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1861 Affected file silcd/packet_send.c.
1863 * Changed the SFTP Filesystem interface. Changed the
1864 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1865 the filesystem operation function. The SilcSFTPFilesystem
1866 is now a context that is allocated by all filesystem allocation
1867 functions and it already includes the operations structure
1868 and filesystem specific context. It is given as argument
1869 now to the silc_sftp_server_start. This made the interface
1870 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1871 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1873 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Changed the backup router adding and getting interfaces
1876 in the server. The router that will be replaced by the
1877 specified backup router is now sent as argument. Affected
1878 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1881 * Added silc_net_addr2bin_ne to return the binary form of
1882 the IP address in network byte order. Affected files
1883 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1885 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Check for existing server ID in silc_server_new_server
1888 and in silc_server_connect_to_router_final and remove the
1889 old entry if it exists. Affected file silcd/packet_receive.c,
1892 * Send the channel message always to only one router, either
1893 in upstream or downstream. Affected file is
1894 silcd/packet_send.c.
1896 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Wrote the definition of the backup resuming protocol to the
1899 protocol specification.
1901 * Removed one redundant channel key generation from normal
1902 server during joining procedure. Removed one redundant
1903 channel key sending from server to router during joining
1904 procedure. Affected file silcd/command.c.
1906 * Made minor bugfixes to the backup router resuming protocol.
1907 Affected file silcd/server_backup.c, server.c.

1916 resume the primary router position in the cell after the
1917 primary router comes back online. Affected files
1918 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1919 and silcd/server_util.[ch].
1921 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * Sleep two (2) seconds after sending QUIT command to server.
1924 Affected file lib/silcclient/command.c.
1926 * Assure that if outgoing data buffer is pending do not force
1927 send any data. Affected file silcd/packet_send.c.
1929 * Assure that if outgoing data buffer is pending do not force
1930 send any data. Affected file lib/silcclient/client.c.
1932 * Implemented the backup router support when the primary router
1933 goes down. The servers and routers can now use the backup
1934 router as new primary router without loosing connectivity.
1936 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1939 in the server to indicate disabled entry. All data read
1940 from the connection will be ignored and no data is sent
1941 for entry that is disabled. Affected files are
1942 silcd/idlist.h, silcd/server.c.
1944 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1951 * Implemented memory filesystem (virtual filesystem) for
1952 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1955 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Implemented the SFTP (SSH File Transfer Protocol) to the
1958 lib/silcsftp. It includes SFTP client and SFTP server
1961 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Moved lib/silccore/silcprotocol.[ch] to the
1964 lib/silcutil library.
1966 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1967 take variable argument list pointer as argument. Affected
1968 file lib/silcutil/silcbuffmt.[ch].
1970 * Added silc_buffer_set function that is used to set data
1971 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1972 Affected file lib/silcutil/silcbuffer.h.
1974 * Changed various routines in the core library to use the new
1975 silc_buffer_set instead of allocating new buffer only for
1978 * Added 64-bit value formatting and unformatting support to the
1979 silc_buffer_[un]format routines. Affected file is
1980 lib/silcutil/silcbuffmt.[ch].
1982 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1983 to includes/bitmove.h.
1985 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Fixed channel user mode saving in client library. Affected
1988 file lib/silcclient/command[_reply].c.
1990 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1992 * Defined the file transfer to the SILC Protocol. Added
1993 new packet type SILC_PACKET_FTP and defined File Transfer
1994 Payload. The mandatory file transfer protocol is SFTP
1995 (SSH File Transfer Protocol). Affected file in addition
1996 of the internet draft is lib/silccore/silcpacket.h.
1998 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1999 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2000 is used as part of backup router protocol when the primary
2001 router of the cell is back online and wishes to resume
2002 the position as primary router.
2004 * Redefined the MAC generation keys in the protocol. The
2005 same key is not used anymore in both direction. Both
2006 direction will now use different keys for sending and
2007 receiving. This fixes a potential security flaw. This
2008 change causes incompatibilities in the protocol.
2010 * Redefined also the MAC computation from the packet.
2011 An packet sequence number is now added to the MAC
2012 computation. This prevents possible replay attacks against
2013 the protocol. This change too causes incompatibilities
2016 Added `sequence' field to the SilcPacketContext to hold
2017 the current sequence number for the packet.
2019 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Added `created' field to the SilcIDListData in the file
2022 silcd/idlist.h to indicate the time when the entry was
2025 * Added `created' field to the SilcChannelEntry too. Affected
2026 file silcd/idlist.h.
2028 * Added `creation_time' aguments to all the announcement functions
2029 in the server. If it is provided then only the entries that
2030 was created after the provided time frame are actually
2031 announced. Affected file silcd/server.[ch].
2033 * The protocol says that the Channel ID's IP address must be
2034 based on the router's IP address. Added check for this in
2035 the silc_server_new_channel when processing incoming New Channel
2036 Payload. Affected file silcd/packet_receive.c.
2038 * Print out the correct version with --version in SILC client.
2039 Affected file irssi/src/silc/core/silc-core.c.
2041 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Fixed WHOWAS command to check for completnes of the client
2044 entry always, not just when the command is coming from client.
2045 Affected file silcd/command.c.
2047 * Added new function silc_server_packet_queue_purge to purge the
2048 outgoing data queue to the network. After the function returns
2049 it is guaranteed that the outgoing packet queue is empty.
2050 Affected file silcd/packet_send.[ch].
2052 * Purge the outgoing packet queue in the rekey protocol's final
2053 callback to assure that all rekey packets go to the network
2054 before quitting the protocol. Affected file silcd/server.c.
2056 * Added silc_client_packet_queue_parse as similar function as
2057 in server to the client library. The affected file is
2058 lib/silcclient/client.c.
2060 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Splitted silcd/server.c and created silcd/server_util.[ch]
2063 for utility functions.
2065 * Added new socket flag SILC_SF_DISABLED to indicate that the
2066 connection is open but nothing can be sent to or received from
2067 the connection. Affected file lib/silcutil/silsockconn.[ch].
2068 The checking for disabled socket is checked in the low level
2069 silc_socket_write and silc_socket_read functions.
2071 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Allow only nicknames and channel names that fits into the
2074 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2076 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * When processing JOIN command reply in server check that if
2079 the channel exists in our global list we'll move it the local
2080 list. Affected file silcd/command_reply.c.
2082 * Fixed the check whether client is joined on the channel already
2083 in JOIN command. Affected file lib/silcclient/command.c.
2085 * Fixed the JOIN command reply to check whether the channel
2086 already exists. Affected file lib/silcclient/command_reply.c.
2088 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Added silc_ske_status_string to map the SKE error numbers
2091 to readable strings. The affected files are
2092 lib/silcske/silcske[_status].[ch].
2094 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Do not show the private channels on the WHOIS channel list
2097 as it is not allowed by the protocol. The affected file is
2100 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Assure that the packet length digged from the actual packet
2103 is something sensible in the silc_packet_decrypt_rest_special
2104 in lib/silccrypt/silcpacket.c.
2106 * Free and NULL the allocated pointer in silc_hmac_alloc if
2107 the HMAC allocation fails. The affected file is
2108 lib/silccrypt/silchmac.c.
2110 * Print the selected security properties to the log files in
2111 the server. Affected file silcd/protocol.c.
2113 * Add SKE's reference counter even if calling the completion
2114 callback manually. Otherwise it goes negative, although it
2115 does not cause any problems. The affected file is
2116 lib/silcske/silcske.c.
2118 * Remove the client entry with short timeout after giving the
2119 KILL command. Affected file lib/silcclient/command.c.
2121 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2122 case all found clients are already disconnected (WHOWAS would
2123 found them) in the server. Affected file silcd/command.c.
2125 * Update the last_receive (time of last data received) to be
2126 updated only when received private or channel message so that
2127 the idle time showed in WHOIS makes more sense.
2129 * Added boolean field `valid' in to the SilcClientEntry in the
2130 client library to indicate whether the entry is valid or not.
2131 This fixes the nickname change bug on channel when changing
2132 the nickname to be same than the old (like nick to Nick) the
2133 nickname formatter doesn't set the new nick anymore to Nick@host.
2134 Affected file lib/silcclient/idlist.[ch].
2136 * Now actually fixed the nickname changing on disconnection.
2137 Added new function silc_change_nick to the Irssi SILC Client.
2138 Affected file irssi/src/silc/core/client_ops.c,
2139 irssi/src/silc/core/silc-nicklist.[ch].
2141 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Check that the public key exists in the GETKEY command before
2144 trying to encode it. Affected file silcd/command.c.
2146 * Print some notifications on received public keys with GETKEY
2147 command in the Irssi SILC Client. Affected files are
2148 irssi/src/fe-common/silc/module-formats.[ch],
2149 irssi/src/silc/core/client_ops.c.
2151 * Use IDENTIFY command to resolve the server information in the
2152 GETKEY command instead of INFO command. Affected file
2153 lib/silcclient/command.c.
2155 * All command reply functions in the client library now calls
2156 the pending command reply callbacks even if an error has
2157 occurred. The server has done this a long time and now it was
2158 time to move the client library to this as well. Now all
2159 errors can be delivered back to the pending command reply
2160 callbacks if necessary. Affected files are
2161 lib/silcclient/command[_reply].[ch].
2163 * Change the nickname on disconnection back to the username
2164 because in reconnect the server will enforce it to it anyway.
2165 Affected file irssi/src/silc/core/silc-servers.c.
2167 * Fixed a config file parsing bug in the Irssi SILC client.
2168 Affected file irssi/src/silc/core/clientconfig.c.
2170 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * When printing the channel mode on JOIN, verify that the
2173 channel key and channel's HMAC are valid. Affected file
2174 irssi/src/silc/core/client_ops.c.
2176 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2179 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2180 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2182 * Removed channel key rekey task deleting from the function
2183 silc_server_save_channel_key. Affected file silcd/server.c.
2184 Added explicit timeout task context instead that is used to
2185 delete the task if we are registering a new task before the
2186 new task has elapsed.
2188 * When channel key rekey occurs the client library now saves
2189 the old channel key for a short period of time (10 seconds) and
2190 is able to use it in case some is still sending channel
2191 messages encrypted with the old key after the rekey. Affected
2192 file lib/silcclient/[idlist.h|client_channel.c].
2194 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Added check to the silc_server_new_id_real to not accept
2197 new ID if it is the sender's own ID. Affected file is
2198 silcd/packet_receive.c.
2200 * Assure that we do not announce ourself or the one we've
2201 sending our announcements when we're router and are announcing
2202 servers to our primary router. Affected file silcd/server.c.
2204 * Fixed silc_server_command_identify_check_client to assemble
2205 correct WHOIS packet. It send corrupted WHOIS packet and
2206 caused problem with router to router connections. Affected
2207 file silcd/command.c.
2209 Fixed also silc_server_command_whois_check the same way
2210 as for the IDENTIFY command.
2212 * Added new SilcIDListStatus to the server in the SilcIDListData
2213 structure. The status now includes the current status of
2214 the entry (like registered, resolved etc.). Affected file
2215 silcd/idlist.[ch]. Defined a bunch of different status types
2216 as well. This replaced the old boolean registered field as well.
2218 Added resolve_cmd_ident field to the SilcClientEntry structure
2219 too so that if the entry is for example being resolved so
2220 another command may attach to the same pending command reply
2221 without requiring to resolve the same entry again. This concept
2222 should optimize the WHOIS and the IDENTIFY resolving under
2223 heavy load by taking away unnecessary resolving for entries
2224 that are being resolved already.
2226 Added support for adding multiple pending commands for one
2227 command idenfier. Affected file silcd/command[_reply].[ch].
2229 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2230 before deleting the data. Otherwise the hash table will have
2231 freed data in comparison functions. Affected file is
2232 silcd/command_reply.c.
2234 * Fixed silc_idlist_replace_client_id to add the new entry to
2235 the cache with NULL nickname. Otherwise there will be invalid
2236 memory as the nickname after the nickname is freed. Affected
2237 file silcd/packet_receive.c.
2239 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2240 saved into wrong slots because the previous number of entries
2241 was not taken into account. Affected file silcd/idlist.c.
2242 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2244 * If we are router and we receive JOIN notify to a channel that
2245 does not have any users then notified client is marked as the
2246 channel founder, as it is it. The affected file is
2247 silcd/packet_receive.c
2249 * Added to the extended hash table API's table_del_*ext functions
2250 the destructor as argument too, so that the caller can decide
2251 which destructor to use or whether to use destructor at all.
2252 Affected file lib/silcutil/silchashtable.[ch].
2254 * Fixed ID Cache purging. It actually deleted the entries from
2255 the hash table after the data was freed. The hash table ended
2256 up comparing freed memory. The affected file is
2257 lib/silccore/silcidcache.c.
2259 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2261 * Fixed Irssi SILC client's KILL command's HELP syntax.
2263 * The USERS command now resolves the detailed user information
2264 if the userinfo field is missing. Affected file is
2265 lib/silcclient/command_reply.c.
2267 * Do not print error in silc_file_read if the read file does
2268 not exist. Just silently return NULL. Affected file is
2269 lib/silcutil/silcutil.c.
2271 * Fixed the silc_log_output to not wine about NULL filename
2272 and to not create some bogus " " filename. Affected file is
2273 lib/silcutil/silclog.c.
2275 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Fixed various printing bugs on the user interface in the
2278 Irssi SILC Client. Minor changes that were forgotten from
2281 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Fixed the configure.in.pre and the compilation and distribution
2284 environment to support the new autoconf 2.52. That version is
2285 now required to compile the CVS trunk.
2287 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2290 to generally parse user@fqdn format strings. Affected file
2291 lib/silcutil/silcutil.c.
2293 * Added nickname_format and nickname_force_format fields to the
2294 SilcClientParams structure. The first one defines the format
2295 for the nicknames that the library will enforce if the receives
2296 multiple same nicknames. The second one is boolean value and
2297 can be used to force the library to always enforce the format
2298 to the nicknames regardles whether there are multiple nicknames
2299 or not. This configurable formatting was employed to flexibly
2300 support accessing multiple nicknames from the user interface.
2301 The userinterface can now set the nicknames to what ever format
2302 they prefer. Affected file lib/silcclient/silcapi.h.
2304 Added function silc_client_nickname_format to the file
2305 lib/silcclient/idlist.c. It performs the nickname formatting.
2307 Added new field `hostname´ to the SilcClientEntry context.
2308 It holds the hostname of the client. Affected file is
2309 lib/silcclient/idlist.h.
2311 * Irssi SILC Client sets the nicknames in nick@hostn format.
2312 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2313 irssi/src/silc/core/silc-core.c.
2315 The WHOIS printing now also shows both the real nickname and
2316 the formatted nickname so that user knows how to access the
2317 user if there are multiple same nicknames cached. Affected
2318 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2319 printing formatting too to take the hostname now as a separate
2320 argument. The Affected file is
2321 irssi/src/fe-common/silc/modules-formats.[ch].
2323 * Changed the silc_client_get_clients_local to accept the formatted
2324 nickname as argument. It accepts the real nickname too but the
2325 formatted nickname can be used to find the true entry from
2326 multiple entries. Affected file lib/silcclient/silcapi.h and
2327 lib/silcclient/idlist.c.
2329 * Added nickname_format_parse field to the SilcClientParams.
2330 It is a callback function provided by the application to parse
2331 the nickname out of the formatted nickname string. The library
2332 calls it to get the nickname from the formatted string. Since
2333 the application generally knows better the format of the nickname
2334 string it parses it instead of the library, even though library
2335 encodes the formatted string. If the callback function is not
2336 provided then the library will use the string as is. The
2337 affected file is lib/silcclient/silcapi.h.
2339 * All the nickname strings passed to the client library in
2340 commands are now expected to be formatted nickname strings.
2341 If the command does not support the formatted nickname string
2342 it will assume that the sent string is the actual nickname.
2343 Affected file lib/silcclient/command.c.
2345 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Added public key authentication support to OPER and SILCOPER
2348 commands in the client library. Affected file is
2349 lib/silcclient/command.c.
2351 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Changed the get_auth_methdod client operation to be asynchronous.
2354 It can be async if the application resolves the authentication
2355 method from the server during the negotiation. Added new
2356 SilcGetAuthMeth completion callback that the application will
2357 call after resolving the authentication method.
2359 Added function silc_client_request_authentication_method that
2360 the application can use to resolve the authentication method
2361 from the server. Added also SilcConnectionAuthRequest callback
2362 that the library will call after the server has replied. The
2363 application can call this function if it does not know the
2364 current authentication method.
2366 Affected files are lib/silcclient/client.c and
2367 lib/silcclient/silcapi.h.
2369 * The Irssi SILC client now automatically resolves the authentication
2370 method incase any configuration information is not present (and
2371 currently there never is). The affected file is
2372 irssi/src/silc/core/client_ops.c.
2374 * Fixed public key authentication from the client library.
2375 Affected file lib/silcclient/protocol.c. Changed also the
2376 protocol specification about the public key authentication in
2377 the connection authentication protocol. The actual data to be
2378 signed is now computed with a hash function before signing.
2380 * Fixed the public key authentication from the server as well.
2381 Affected file silcd/protocol.c.
2383 * Removed the mlock()'s from the memory allocation routines.
2384 Affected file lib/silcutil/silcmemory.c. The ./configure does
2385 not check anymore for the mlock(). Affected file is
2388 * Fixed USERS command in server to allow the execution of the
2389 command for private and secret channels if the client sending
2390 the command is on the channel. Affected file silcd/command.c.
2392 * Fixed silc_client_get_clients_local to return the clients
2393 count correctly. It could return wrong value. Affected file
2394 lib/silcclient/idlist.c.
2396 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2399 types. The assembler optimizations seemed not to like 64-bit
2400 data types. The assmebler optimizations thus are now enabled
2401 also for BSD systems as opposed to only enable them for Linux.
2403 * Do not check for threads at all on BSD systems. Affected
2404 file configure.in.pre.
2406 * Removed -n and -h options from the Irssi SILC Client since
2407 they are not used in silc.
2409 * Fixed the prime generation to assure that the first digit
2410 of the generated random number is not zero since our conversion
2411 routines does not like number strings that starts with zero
2412 digit. If zero digit is seen the random number is regenerated.
2413 This caused some corrupted RSA keys when the zero first digit
2414 was met. Affected file lib/silcmath/silcprimegen.c.
2416 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Fixed WIN32 configuration in the ./configure script.
2419 Fixed to include xti.h on environments that has it.
2420 Patches by Carsten Ilchmann and andrew.
2422 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Changed the silc_id_create_client_id to be collision
2425 resistant. It is now assured that there cannot be created
2426 two same client ID's. I suspect that some weird bugs in
2427 the server were actually caused by duplicate Client IDs.
2428 Affected file silcd/serverid.[ch]. A router receiving
2429 new ID now also assures and informs the sending server
2430 if the ID caused collision.
2432 * Changed the silc_id_create_channel_id to also assure that
2433 there are no collisions.
2435 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Statement about ignoring the Mutual Authentication flag when
2438 performing rekey with PFS was a bit misleading. It is ignored
2439 if it was set in the initial negotiation, it cannot be even
2440 set in the rekey. Fixed in the ke-auth draft. Started the
2441 new versions of the protocol drafts in the doc/.
2443 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Fixed a bug in silc_client_command_identify_save when saving
2446 new channel information. The channel name was no duplicated
2447 and caused crash on exit. Affected file is
2448 lib/silcclient/command_reply.c.
2450 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Fixed the getkey command handling in the server. Send just
2453 empty OK reply to the sender if the key could not be fetched
2454 (but everything else was ok, like the key just was not available).
2455 Changed the public key parameter to optional in the protocol
2456 specs so that empty OK reply can be sent. Affected file
2459 Added a message to Irssi SILC client to tell to user if the
2460 server did not return a public key.
2462 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Fixed a channel key regeneration bug. It registered new
2465 timeout tasks exponentially until all system resources were
2466 used. Affected file silcd/server.c.
2468 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Added the SILC Document generator to the scripts/silcdoc.
2471 It can be used to generate the Toolkit Reference Manual out
2472 of the source tree. Internally it will also use the RoboDoc
2473 generator now imported in util/robodoc.
2475 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Added couple of return's in rekey protocol if error orccurred
2478 during the protocol. The execution must be terminated.
2479 Affected file silcd/protocol.c. Also, terminate the protocol
2480 always with timeout.
2482 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * The client's Client ID was created initally from the wrong
2485 nickname (it could have been in format nick@host) in the
2486 silc_server_new_client. Affected file silcd/packet_receive.c
2488 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Added some SILC_LOG_ERROR's to various error conditions
2491 if client could not be added to ID cache. Affected files
2492 silcd/packet_receive.c and silcd/server.c.
2494 * When client's sock->user_data is freed, NULL also the
2495 client->router and client->connection pointers. Added check
2496 for these pointers being NULL to various places around the
2497 code. Affected file silcd/server.c.
2499 * Added client->data.registered == TRUE checks to various
2500 places around the code to assure that unregistered client's
2501 are not handled when it is not allowed. Affected file
2504 * Added `bool registered' fields to all
2505 silc_idlist_[server|client]_get_* routines to indicate whether
2506 the fetched client needs to be registered or not. Affected
2507 file silcd/idlist.[ch].
2509 * Add your own entry as registered to the ID cache in the
2510 server. Affected file server.c.
2512 * Fixed a bug in silc_server_new_server. The SilcServer was
2513 set as the new server's context instead of SilcServerEntry.
2514 This naturally caused some weird bugs.
2516 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2518 * Do not delete the channel rekey task when adding it
2519 for in silc_server_create_channel_key.
2521 * Changed the silc_server_create_channel_key to return
2522 TRUE or FALSE to indicate the success of the channel key
2525 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Fixed MSVC++ project files and added missing files to
2528 Makefiles under win32/.
2530 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Do not add TCP_NODELAY flag if the operating system
2533 does not have it defined. Affected files are
2534 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2536 * Fixed buffer overflow from Irssi SILC Client. Affected
2537 file irssi/src/fe-common/core/themes.c.
2539 * Fixed double free in client library in the file
2540 lib/silcclient/client.c when disconnecting from server.
2542 * Applied double free patch from cras to Irssi SILC client.
2543 Affected files irssi/src/core/[modules/expandos].c
2545 * Fixed the disconnection handling to Irssi SILC Client.
2546 The application must call silc_client_close_connection
2547 in ops->connect client operation in case of failure of
2548 the connection. Affected file is
2549 irssi/src/silc/core/client_ops.c.
2551 * Do not set sock->protocol to NULL in the function
2552 silc_client_close_connection after executing the protocol's
2553 final callback since the sock might not be valid anymore.
2554 Affected file lib/silcclient/client.c.
2556 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Do not enable SILC_THREADS if the linking with libpthread
2559 did not happen. Affected file configure.in.pre.
2561 * Added notion to protocol specification that server must
2562 verify the sent authentication payload with CMODE when
2563 setting the channel founder key. Implemented it to the
2564 server. Affected file silcd/command.c.
2566 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Added _EXTRA_DIST SILC distribution variable to the
2569 distributions file. It is used to conditionally add extra
2570 files or directories to the specific distribution. Affected
2571 files ./prepare, Makefile.am.pre and distributions.
2573 Removed the `_' from the start of the distribution names.
2576 * Added README.WIN32 for instructions to compile the Toolkit
2579 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Fixed a double free in disconnection in the server. Affected
2582 file is silcd/server.c.
2584 * Fixed the lib/silcske/groups.c to work now also with GMP
2585 MP library. The string conversion did not work when using
2586 specific base and the base is indicated in the string as well.
2588 * Created win32/ directory which now includes MSVC++ specific
2589 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2590 It will appear only in the toolkit distribution
2592 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Changed the key material distribution function in case when
2595 the hash output is too short. The data is now concatenated
2596 a bit differently than it used to. Made the change to the
2597 SKE protocol specification.
2599 * Added better GMP detection to configure.in.pre. A patch
2602 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Fixed a minor bug in SKE that might cause some problem on
2605 some platforms. Affected file lib/silcske/silcske.c.
2607 * Added the cookie checking for initiator in the SKE. It checks
2608 that the responder returns the sent cookie unmodified. The
2609 affected file is lib/silcske/silcske.c. Added new SKE
2610 error type INVALID_COOKIE that can be sent during the
2611 negotiation. Fixed some memory leaks as well.
2613 * Added the "invalid cookie" error message to Irssi SILC client's
2616 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2618 * Added `task_max' field to the SilcClientParams to indicate
2619 the maximum tasks the scheduler can handle. If set to zero,
2620 default values are used. Affected file lib/silcclient/silcapi.h.
2622 * Fixed memory leaks in silc_client_close_connection. Affected
2623 file lib/silcclient/client.c.
2625 * Added silc_client_del_client_entry to client library to free
2626 all memory of given client entry. Affected file is
2627 lib/silcclient/idlist.[ch].
2629 * Added new functions silc_client_del_channel and
2630 silc_client_del_server to delete channel and server entries.
2631 Affected file lib/silcclient/[silcapi.h/idlist.c].
2633 * Removed silc_client_del_client_by_id from silcapi.h.
2635 * Fixed the INFO command to return the server's own info
2636 correctly when querying by Server ID. Affected file is
2639 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Removed the non-blocking settings in WIN32 code in the
2642 silc_sock_[read/write] and added SleepEx instead. Affected
2643 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2644 of input data is now checked with FIONREAD and ioctlsocket.
2646 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Call silc_schedule_task_del_by_context in the
2649 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2650 Affected file lib/silccore/silcprotocol.c.
2652 * Call silc_protocol_cancel for active protocols in the
2653 silc_server_close_connection if the funtion
2654 silc_server_free_sock_user_data has not been called.
2655 Affected file silcd/server.c.
2657 * Generic tasks cannot be deleted using the del_by_fd
2658 task deleting function since generic tasks does not match
2659 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2661 * Added a notion to SILCOPER help file that the SILCOPER works
2662 only on router server, not on normal server.
2664 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Added for WIN32 support for the new scheduler as well.
2667 Affected file lib/silcutil/win32/silcwin32schedule.c.
2669 * Fixed the SHA1 implementation to work on various platforms.
2671 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2674 API. It is part of the scheduler now. Everything else is
2675 as previously but some functions has changed their names.
2676 Checkout the lib/silcutil/silcschedule.h for the interface.
2677 Updated all applications to use the new interface. Affected
2678 files are lib/silcutil/silcschedule.[ch].
2680 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Found a bug in the SKE implementation. The HASH value,
2683 specified by the protocol, was not computed correctly. The
2684 public key of the responder was not added to the computation
2685 even though it is mandatory. Affected file lib/silcske/silcske.c.
2686 This unfortunately causes incompatibilities with older
2687 clients and servers.
2689 * Added WIN32 specific network init and uninit functions:
2690 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2691 the Winsock2. Affected file lib/silcutil/silcnet.h and
2692 lib/silcutil/win32/silcwin32net.c.
2694 * Set the socket always to nonblocking mode on WIN32 after
2695 reading data or writing data. Affected file is
2696 lib/silcutil/win32/silcwin32sockconn.c.
2698 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Fixed various compilation problems under WIN32. Affected
2701 files lib/silcutil/win32/silcwin32thread.c and
2702 lib/silcutil/win32/silcwin32schedule.c.
2704 * Removed all _internal.h #includes from public header
2705 files. Internal headers must never be included from
2708 Removed also the lib/silcske/payload_internal.h file.
2710 * All include files that may be needed (public and some others
2711 included by the public headers) by application developers are
2712 now copied to the ./includes directory. It does not copy any
2713 internal headers. Affected file Makefile.defines.pre and all
2714 Makefile.am's under lib/ and subdirs.
2716 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Do not change the ~/.silc directory's permissions automatically.
2719 Affected file irssi/src/silc/core/clientutil.c.
2721 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Do not cancel the protocol in silc_server_close_connection
2724 it might cause recursion. Now cancelled in the function
2725 silc_server_free_sock_user_data. Affected file silcd/server.c.
2727 * Fixed the silc_server_remove_clients_by_server to regenerate
2728 the channel keys correctly finally. Added also new function
2729 silc_server_remove_clients_channels to actually do it.
2730 Affected file silcd/server.c.
2732 * Fixed the silc_server_new_channel to not crash by giving
2733 wrong router to the new channel. Affected file is
2734 silcd/packet_receive.c.
2736 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2739 which is given as argument to the silc_client_alloc now.
2740 It can be used to configure the client and set various parameters
2741 that affect the function of the client.
2743 * The USERS command in server did not check whether the channel
2744 is private or secret. Affected file silcd/command.c.
2746 * Added new argument to the USERS command in protocol specification.
2747 The USERS command now can take the channel name as argument
2748 as well. Added support for this in client and server and
2749 updated the protocol specs.
2751 * Completed the GETKEY command in client. It can be now used
2752 to fetch also servers public key not only some clients.
2753 Affected files lib/silcclient/command[_reply].c.
2755 * Added silc_client_get_server to return server entry by the
2756 server name. Affected files lib/silcclient/silcapi.h and
2759 * Redefined the IDENTIFY command in protocol specification to be
2760 more generic. It now can be used to query information about
2761 any entity in the SILC Network, including clients, servers and
2762 channels. The query may be based either the entity's name
2763 or the ID. Added support for this in both client and server.
2765 Affected files silcd/command.c and lib/silcclient/command.c
2766 and command_reply.c.
2768 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2769 the _from_client and _from_server functions. Affected file
2772 * Added silc_client_get_channel_by_id_resolve to the file
2773 lib/silcclient/silcapi.h to resolve channel information by
2774 its ID. Added also silc_client_get_channel_by_id that
2775 does not resolve it from the server.
2777 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Added SilcServerEntry context into the client library
2780 to represent one server. The INFO command now allocates
2781 these to save the resolved server info. For now on the
2782 client library will also keep information about servers,
2783 connected and resolved with INFO.
2785 The INFO command now allocates the SilcServerEntry context
2786 and saves the server info there. The COMMAND_REPLY in
2787 the INFO now returns the parameters to application in
2788 same order as defined in the protocol specification.
2790 The entries are cached in the client->server_cache.
2792 * The INFO command is now issued after received the Client ID
2793 from the server. Affected file lib/silcclient/client.c.
2795 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2796 to the application as the mode changer might be server.
2797 It is guaranteed that NULL is not returned anymore to the
2798 application. Affected file lib/silcclient/client_notify.c.
2800 The ID Type is now also passed to the application so that
2801 it can check whether the returned entry is SilcClientEntry
2804 Added new function silc_client_get_server_by_id to return
2805 the server entry by ID. Affected files are the
2806 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2808 * Do not create the channel in the Irssi SILC Client when issuing
2809 the JOIN command but when received the sucessful JOIN command
2810 reply. Otherwise the channel might get created even though we
2811 could not join it. The Affected file is
2812 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2814 * Fixed a channel joining bug in router. The router must also
2815 check the channel modes, invite and ban lists etc. when serving
2816 the JOIN command sent by normal server. Affected file is
2817 silcd/command.c. The router now resolves the client's
2818 information from the server who sent the JOIN command if it
2819 does not know it, and processes the JOIN command only after
2822 * Changed the SilcCommandCb to take new argument; void *context2.
2823 Affected file lib/silccore/silccommand.h
2825 The second argument in the command callbacks in the server now
2826 includes the SilcServerCommandReplyContext if the command was
2827 called as pending command callback from the command reply.
2828 Otherwise it is NULL. When called as pending the status of the
2829 command reply will be checked and if it was erronous the
2830 error will be sent to the original sender of the command.
2831 This way the client always receives the error messages even
2832 though the server was actually the one who received the error
2833 when it resent the command to router, for example. Affected
2834 files silcd/command[_reply].[ch].
2836 * Fixed sending WHOWAS command's error message to client if
2837 the requested client could not be found. It was missing.
2840 * Changed the CMODE and CUMODE commands reply arguments in the
2841 protocol specification. The Channel ID is now sent in both
2842 of the commands to identify the channel. Implemented this
2843 new feature to the client and server. Affected files
2844 lib/silcclient/command_reply.c and silcd/command.c.
2846 * Made better checks for invite and ban lists in the JOIN
2847 command in server. Affected file silcd/command.c.
2849 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * The server now performs the incoming host IP/DNS lookup
2852 using the silc_socket_host_lookup and thus does not block
2853 the server anymore. Affected file silcd/server.c.
2855 * Completed the multi-thread support for SILC Scheduler in
2856 the lib/silcutil/silcschedule.c.
2858 * Fixed the configure.in.pre to detect the pthread correctly
2861 * Fixed a deadlock in silc_task_queue_wakeup in the file
2862 lib/silcutil/silctask.c.
2864 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Added new function silc_schedule_wakeup that is used in
2867 multi-threaded environment to wakeup the main thread's
2868 schduler. It needs to be used when a thread adds a new task
2869 or removes a task from task queues. After waking up, the
2870 scheduler will detect the task queue changes. If threads
2871 support is not compiled in this function has no effect.
2872 Implemented the wakeup mechanism to both Unix and WIN32
2873 systems. Affected files are lib/silcutil/silcschedule.[ch],
2874 lib/silcutil/unix/silcunixschedule.c and the
2875 lib/silcutil/win32/silcwin32schedule.c.
2877 * Added new function silc_task_queue_wakeup to wakeup the
2878 scheduler by the specified task queue. Affected file
2879 lib/silcutil/silctask.[ch].
2881 * The silc_socket_host_lookup_start now wakes up the scheduler
2882 after adding the timeout task. Affected file is
2883 lib/silcutil/silcsockconn.c.
2885 * The silc_socket_host_lookup is synchronous now if the threads
2886 support is not compiled in. However, the callback is still
2887 called asyncronously through the scheduler, anyway. Affected
2888 file lib/silcutil/silcsockconn.c.
2890 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Added new function silc_socket_host_lookup to perform
2893 asynchronous IP and FQDN lookups for the socket connection.
2894 Affected files lib/silcutil/silcsockconn.[ch].
2896 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2899 that may or may not compile the mutex support in.
2901 Changed the silc_mutex_alloc interface. It allocates the
2902 mutex now to the sent pointer and returns TRUE or FALSE.
2904 Affected file lib/silcutil/silcmutex.h.
2906 * Wrote the SILC Task Queue interface to support multi-threads.
2907 Affected file lib/silcutil/silctask.[ch].
2909 * Wrote the SILC Scheduler to support multi-threads. Affected
2910 file lib/silcutil/silcschedule.c.
2912 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2914 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2915 in lib/silcutil/win32/.
2917 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Defined SILC Mutex API and SILC Thread API and implemented
2920 them for Unix. Affected files are
2921 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2922 lib/silcutil/unix/silcunixmutex.c and
2923 lib/silcutil/unix/silcunixthread.c.
2925 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Fixed the silc_server_remove_clients_by_server's channel
2928 key re-generation. The hash table handling was incorrect
2929 and would not work with many channels. Affected file is
2932 * Fixed some memory leaks around the server code.
2934 * Rewrote the silc_server_get_users_on_channel to support IPv6
2935 based Client ID's. Affected file silcd/server.c.
2937 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2938 specification. However, a separate document must be written
2939 to define the detailed signing procedure and the payload
2940 associated with the flag. Defined the flag to the
2941 lib/silccore/silcchannel.h as well.
2943 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Changed the dynamic tables to static size tables in the
2946 lib/silccrypt/silchmac.c.
2948 * Removed GCC dependencies from the code. A patch by cras.
2950 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Do not show the error "Error receiving packet bla bla"
2953 in server if it really was not an error (-2 means that reading
2954 is pending). Affected file silcd/server.c.
2956 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Fixed a possible crash in silc_server_remove_clients_by_server
2959 in silcd/server.c. Fixed there also some memory leaks.
2961 * Fixed the silc_idlist_replace_client_id. It could replace
2962 wrong key in the hash table. Affected file silcd/idlist.c.
2964 * Do not check whether there are global users on the channel
2965 if the channel->global_users is FALSE. Affected functions
2966 silc_server_remove_from_one_channel and
2967 silc_server_remove_from_channels in silcd/server.c. Also,
2968 do not check if the removed client is local as we can be
2969 sure that global client was not removed from the channel
2970 and checking for global users is not needed.
2972 * The silc_server_remove_clients_by_server now re-generates
2973 the channel keys correctly for those channels that had
2974 clients removed from them. Affected file silcd/server.c.
2976 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Found the reason of random crashes in the server. We weren't
2979 ignoring the SIGPIPE signal (which can be sent in write())
2980 and it crashed the server. Affected file silcd/silcd.c.
2982 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * Assure that sock->user_data is not NULL in the function
2985 silc_server_packet_send in silcd/packet_send.c.
2987 * Disconnect the remote connection if it could not be added
2988 to any ID lists in the server. The affected file is
2991 * Check in silc_server_packet_send[_real/dest] that the
2992 socket is not disconnecting and ignore the data if it is.
2993 Affected file silcd/packet_send.c.
2995 * Define inline to __inline on native WIN32 compilation.
2996 Affected file includes/silcwin32.h.
2998 * Added some explicit type casts for inline code since MSVC
2999 require them. Affected files lib/silcutil/silcbuffer.h,
3000 lib/trq/silcdlist.h and lib/trq/silclist.h.
3002 * Print warning in log files from now on if the packet
3003 decryption fails. Affected file silcd/server.c.
3005 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Changed the `say' client operation's interface to accept
3008 new `type' argument to indicate the type of the message sent
3009 by the library. The application may filter the library's
3010 messages according the type. The affected file is the
3011 lib/silcclient/silcapi.h.
3013 * Added two new functions to lib/silcclient/silcapi.h:
3014 silc_client_del_client and silc_client_del_client_by_id.
3015 Affected file lib/silcclient/idlist.c.
3017 * Moved the clientincludes.h from includes/ to silc/ and
3018 serverincludes.h from includes/ to silcd/.
3020 * The modes for the CMODE and CUMODE are now passed as
3021 uint32 for application with COMMAND_REPLY. The affected
3022 file is lib/silcclient/command_reply.c.
3024 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * /WHOIS without arguments shows client's own information.
3027 Affected file lib/silcclient/command.c.
3029 * Changed PING to not accept any arguments. The specs
3030 says that client can ping only the connected server so
3031 requiring an argument is not needed. Affected file is
3032 lib/silcclient/command.c.
3034 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Fixed a fatal bug in private message sending and reception
3037 encryption and decryption when using private message keys.
3038 The implementation was incorrect and did not follow the
3039 specification. It causd that some of the message were
3040 lost since it did not use the sending and receiving keys
3041 as the protocol suggests. This has been fixed and will cause
3042 incompatibilities with older clients when sending private
3043 message encrypted with private message keys. Affected files
3044 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3045 and various other in Irssi SILC Client.
3047 Added `responder' boolean argument to the functions
3048 silc_client_add_private_message_key[_ske] to indicate when
3049 the key is added as responder or initiator of the key
3052 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3054 * Removed the silc_ske_check_version function and created
3055 a SilcSKECheckVersion callback. Added also a function
3056 silc_ske_set_callbacks that is now used to set all SKE
3057 callbacks. The callback functions are not given to
3058 the SKE functions anymore, but this function is used to
3061 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3063 * Added `silc_version' argument to the silc_client_alloc
3064 to define the version of the application for the library.
3065 The library will use the version string to compare it
3066 against the remote host's (usually a server) version
3067 string. Affected file lib/silcclient/silcapi.h
3069 * Added the KE protocol context to Key Agreement context
3070 in client library so that we can abort the SKE if it
3071 is in process when we get timeout. Affected file is
3072 lib/silcclient/client_keyagr.c.
3074 * Do not resolve the client ID forever if it returns in the
3075 first time that such client does not exist. This was done
3076 for example with private message. Affected file is
3077 lib/silcclient/client_prvmsg.c.
3079 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Do not add regex.h for WIN32. The affected file
3082 includes/silcincludes.h.
3084 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3085 not work yet 100%. It generates the DLL's automatically
3086 when compiling with --with-win32 under cygwin.
3088 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3090 * lib/contrib/regex.c is not compiled on WIN32.
3092 * Added silc_net_get_socket_opt function to the
3093 lib/silcutil/silcnet.h.
3095 * Added includes/silcwin32.h for WIN32 specific includes
3098 * Do not use ptime structure or any of the posix process
3099 functions on WIN32 in lib/silccrypt/silrng.c.
3101 * Added silc_gettimeofday to provide generic function
3102 for struct timeval on all platforms. Added the function
3103 to lib/silcutil/silcutil.h.
3105 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3108 library as they clearly belong there. As a plus side we
3109 can make the actual socket connection routines platform
3112 Added also new generic function silc_socket_read and
3113 silc_socket_write (that used to be silc_packet_[read/write].
3114 The implementation of these are platform specific.
3116 * Added WIN32 specific routines of silc_socket_[read/write]
3117 to lib/silcutil/win32/silcwin32sockconn.c.
3119 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Added preliminary support for native WIN32 compilation under
3122 cygwin (using the -mno-cygwin option for GCC) to the
3123 ./configure.in.pre. The --with-win32 now prepares the
3124 compilation for native WIN32.
3126 * Rewrote the SILC Scheduler interface in the file
3127 lib/silcutil/silcschedule.h. The scheduler is now context
3128 based and does not have anymore any global static scheduler.
3129 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3130 and created lib/silcutil/win32 directory for WIN32 based
3133 * Added Unix specific network routines to the
3134 lib/silcutil/unix/silcunixnet.c and the old
3135 lib/silcutil/silcnet.c includes now only generic routines.
3137 Added WIN32 specific network routines to the
3138 lib/silcutil/win32/silcwin32net.c.
3140 * Added Unix specific utility functions from the
3141 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3143 * Added WIN32 SILC Scheduler to the file
3144 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3147 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3149 * Do not handle JOIN notify in the server if the target client
3150 is not registered (idata->registered == FALSE). The affected
3151 file is silcd/packet_receive.c.
3153 * Update the nickrec->founder in event_cumode in the Irssi SILC
3154 client. Affected file irssi/src/silc/core/silc-channels.c.
3156 * Fixed the CUMODE_CHANGE notify handling in the server when
3157 server and router are announcing their clients on channels.
3158 Now the mode changes are saved and notified correctly. The
3159 affected file is /silcd/packet_receive.c.
3161 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3162 They really did not replace the cache entry in the ID Cache.
3163 Now they do that. Affected file silcd/idlist.c.
3165 * Fixed the KICK notify handling in the Irssi SILC client to
3166 update the channel records so that the kicked client does not
3167 appear to be on the channel. The affected file is
3168 irssi/src/silc/core/silc-channels.c.
3170 * Always update the conn->current_channel when executing command
3171 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3173 * Fixed the KILL notify handling in Irssi SILC client to remove
3174 the killed client on all channels.
3176 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Fixed the silc_parse_command_line to remove extra spaces
3179 from the start and end of the arguments. Affected file is
3180 lib/silcutil/silcutil.c.
3182 * Cancel and free any active protocol in the function
3183 silc_server_close_connection. Affected file silcd/server.c.
3185 * Cancel and free any active protocol in the function
3186 silc_client_close_connction. Affected file is
3187 lib/silcclient/client.c.
3189 * Do not execute the KILL command for clients that are in
3190 history (ie. they are not in the network). Affected file is
3193 * Fixed KILL notify handling, client does not crash anymore.
3194 Affected file irssi/src/silc/core/silc-channels.c.
3196 * Reduced the default packet buffer size from 2048 to 1024 in
3197 lib/silccore/silcpacket.c.
3199 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3200 counter to the SKE context that is incresed when the SKE library
3201 performs async operation outside the library. If the outside
3202 process frees the SKE context and FREED status will be set
3203 and the library will detect after the sync operation that the
3204 libary is freed. The affected files are
3205 lib/silcske/silcske[_status].[ch].
3207 * Resolve the client entry information in the function
3208 silc_client_channel_message to assure that NULL pointer is not
3209 passed as client entry to the application. */
3211 * Fixed the task timeout calculation to assure that there is
3212 never negative timeouts. The affected file is
3213 lib/silcutil/silcschedule.c.
3215 * Fixed the channel user mode notification sending in server.
3216 It was sent point-to-point to the router (or to server by router)
3217 but it needs to be destined to a channel. The routines now
3218 supports sending the channel user mode notifys to the channels
3219 when announcing clients and channels. Affected files are
3220 silcd/server.c and silcd/packet_receive.c.
3222 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3223 It did not actually replace the old channel entry in the cache.
3224 Affected file lib/silcclient/client_notify.c.
3226 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Fixed a possible crash in silc_packet_send_prepare. It now
3229 assures always that there is enough space in the buffer and
3230 at the tail area of the buffer (for MAC).
3232 Fixed the inbound buffer reallocation in silc_packet_read.
3233 It was old code and did not handle the reallocation correctly.
3236 The affected file is lib/silccore/silcpacket.c.
3238 * Fixed buffer overflow in silc_parse_nickname in the file
3239 lib/silcutil/silcutil.c.
3241 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * make install generates new server keys only if there is not
3246 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3249 Added check that if the NOREPLY is set then we will not send
3250 the away message. This avoids infinite loop of away messages
3251 if both clients are away. The affected file is
3252 lib/silcclient/client_prvmsg.c.
3254 * Fixed client crash if /NICK was given without arguments.
3255 Affected file lib/silcclient/command.c.
3257 * Server does not send the invite list in INVITE command back
3258 to the client if the list was not altered. Added this notion
3259 to the protocol spec as well. Affected file silcd/command.c.
3261 Fixed possible crash in INVITE command by checking the
3262 value of silc_server_get_client_route command.
3264 * Fixed the INVITE notify type handling. The arguments are now
3265 taken in correct order and client does not crash. The affected
3266 file is irssi/src/silc/core/silc-channels.c.
3268 Removed the "Inviting xxx to channel" message from the
3269 client library away and let the application handle it.
3270 Affected file lib/silcclient/command.c. Added that message
3271 to Irssi SILC client's message formats.
3273 * Fixed CMODE command crash in client. It now checks the
3274 amount of arguments correctly and does not crash. The affected
3275 file is lib/silcclient/command.c.
3277 * Do not create new channel automatically in silc_channels_join
3278 but check whether the channel by that name already exists.
3279 Affected file irssi/silc/core/silc-channels.c.
3281 * Do not send the SERVER_SIGNOFF to router if the disconnected
3282 entity was the router. Affected file silcd/server.c.
3284 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3285 SILC client as it was missing from there.
3287 Added the handling of the KICK notify to the Irssi SILC client
3288 as it was missing. Added "you have been kicked" message to
3289 Irssi SILC client's message modules formats.
3291 Added the handing of the KILL notify to the Irssi SILC client
3292 as it was missing. Added the kill message module formats
3295 The affected file is irssi/src/silc/core/silc-channels.c.
3297 * The router did not save the channel mode the server announced.
3298 Affected file silcd/packet_receive.c.
3300 * Fixed a possible crash in INFO command in server. If the
3301 server did not provide the server info it crashed. Affected
3302 file silcd/command.c.
3304 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Fixed the GETKEY command in the server to check also the
3307 global list. Otherwise the GETKEY would not work correctly
3308 in normal SILC server. Affected file silcd/command.c.
3310 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Fixed GETKEY crash, it crashed if the command did not succseed.
3314 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3317 is now real and not just an macro interface to GMP.
3319 Removed the entire GMP from the source tree and imported new
3320 NSS MPI library instead. Reason for removing GMP is that it is
3321 extremely large and compiles extremely slow. The NSS MPI
3322 is only a few files and compiles in less than 10 seconds.
3323 The speed is also about the same as GMP. The MPI is imported
3324 to lib/silcmath/mpi.
3326 If the system has GMP installed we will still use the GMP.
3327 If it is not then the NSS MPI will be compiled.
3329 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Merged a long nickname (127 characters long) crash bugfix from
3332 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3334 * Merged a freed memory reference bugfix from Irssi CVS tree.
3335 Affected file irssi/src/core/commands.c.
3337 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Added the server's public key sving and verification to the
3340 server when performing the SKE. This was missing and the
3341 remote server's (or router's) public key was accepted without
3342 checking whether we have it previously or trust it at all.
3343 Affected file silcd/protocol.c.
3345 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Check in the silc_server_timeout_remote if protocol is active
3348 and make sure that the protocol's final callback is called so
3349 that all memory if freed. Affected file silcd/server.c.
3351 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * silc_server_whois_send_reply crashed the server if the nickname
3354 was 127 characters long. Affected file silcd/command.c.
3356 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Added sanity check to the silc_server_new_client. If the hostname
3359 is provided inside username then check that the provided hostname
3360 really is the same as the resolved one. If the hostname was not
3361 resolved then check it from the public key. Affected file is
3362 silcd/packet_receive.c.
3364 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3365 if the server disconnected us and the connection is not valid
3366 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3368 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3369 the library to the lib/silcutil/silcutil.[ch].
3371 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Close log file after open. Affected file
3374 lib/silcutil/silclog.c.
3376 * Check whether sock == NULL in silc_client_send_packet and return
3377 if it is. Affected file lib/silcclient/silcclient.c.
3379 * Check rec->entry == NULL in the Irssi SILC Client before
3380 sending the channel message. Affecte file is
3381 irssi/src/silc/core/silc-servers.c.
3383 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Merged a splitted window bugfix from Irssi CVS tree. The
3386 affected file is irssi/src/fe-text/textbuffer-view.c.
3388 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3389 It did not print nickname.
3391 * Improved the distributions system a bit.
3393 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3396 irssi/src/fe-text/gui-window.c.
3398 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3399 to in-active server. The affected file is
3400 irssi/src/silc/core/client_ops.c.
3402 * Resolve the client in USERS command reply if the entry does
3403 not have username resolved. The affected file is
3404 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3405 command to WHOIS command to really resolve stuff. The USERS
3406 is not used any more in any critical section so WHOIS can
3407 be used even though it might be slower than IDENTIFY.
3409 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3412 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Changed the protocol API a bit more consistent in the
3415 lib/silccore/silcprotocol.[ch].
3417 * Changed the following headers to ROBODoc format:
3419 lib/silccore/silcpayload.h
3420 lib/silccore/silcprotocol.h
3421 lib/silccore/silcsockconn.h
3423 All core library headers are now formatted.
3425 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Fixed a bug in Irssi SILC client; do not show that you are
3428 server/router operator if you really are not. Affected file is
3429 irssi/src/silc/core/client_ops.c.
3431 * Renamed silc_command_free_payload to silc_command_payload_free.
3432 Affected file lib/silccore/silccommand.h
3434 * Added silcmath.h to include the prototoypes of various routines
3435 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3438 * Changed the following headers to ROBODoc format:
3440 lib/silccore/silcchannel.h
3441 lib/silccore/silccommand.h
3442 lib/silccore/silcid.h
3443 lib/silccore/silcidcache.h
3444 lib/silccore/silcmode.h
3445 lib/silccore/silcnotify.h
3446 lib/silccore/silcpacket.h
3447 lib/silcmath/silcmath.h
3449 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Added checking to the server code not to start the server if
3452 ciphers and stuff are not configured properly. Affected files
3453 silcd/serverconfig.[h] and silcd/server.c.
3455 * Changed the layout of the header files of the public interfaces
3456 in the SILC libraries. The new layout supports ROBODoc
3457 documentation tool (and some others) so that it is easy to create
3458 a library reference manual. All the other headers and source
3459 code must still follow the CodingStyle document. Also source
3460 code must not include these ROBODoc stuffs, only the headers.
3461 Furthermore, all public interface headers must now be named
3462 by using `silc' prefix, example: silcapi.h, silccipher.h.
3463 Some files were renamed due to this. All the other headers
3464 must not be used as public interfaces. I will update the
3465 CodingStyle document later. Changed following headers, so far:
3467 lib/silcclient/silcapi.h
3468 lib/silccore/silcauth.h
3469 lib/silccore/silcprivate.h
3470 lib/silccrypt/silcdh.h
3472 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Removed silc_client_packet_send_flush from the client library
3477 as it is not needed. Affected file lib/silcclient/client.[ch].
3479 * Added printing of message of unresolved authentication method
3480 to the Irssi SILC client. Added it to the module formats.
3481 Removed the same message from the client library.
3483 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added new distribution feature, DISTLABEL. Every distribution
3486 can define own preprocessor label that can be used in the
3487 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3488 file distributions, acconfig.h.pre and prepare.
3490 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Added Makefile.defines_int to include the actual definitions
3493 for Makefile.defines.in. Tested the new distribution system,
3494 created distributions and tested installation.
3496 * Added AWAY message printing to the Irssi SILC client. Added
3497 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3499 * Added SCONNECT command to call the SILC's CONNECT command.
3500 Cannot use CONNECT directly since Irssi uses that internally.
3501 Affected file irssi/src/silc/core/silc-servers.c.
3503 Added ACTION local command. It is same as ME command but takes
3504 the channel as mandatory argument.
3506 Rewrote some of the Irssi's help files to suite for SILC
3509 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Added Makefile.defines[.in] that should for now on be included
3512 in all Makefile.am file in the source tree. That file includes
3513 all common compilation definitions for SILC source tree.
3515 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Minor changes to the ./prepare script to change the package
3518 name according the distribution name to the configure.in.
3520 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Created new distribution system. Added file `distributions'
3523 that defines all the distributions that can be created out of
3524 the SILC source tree. The ./prepare script now reads that
3525 file to determine how to prepare the distributions. The
3526 first argument to the ./prepare is the name of the distribution
3527 and second is the version of the distribution. If given
3528 without arguments it creates the default (toolkit) distribution
3529 with the default version (defined in ./prepare).
3531 All Makefile.am files that are subject to the distributions
3532 are now named as Makefile.am.pre. These are ./Makefile.am
3533 and lib/Makefile.am. Others may be changed later.
3535 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Added invite list, ban list, some key management and connection
3538 error message printing to module formats in the Irssi SILC client.
3540 * Added new silc_client_set_away_message to set the away message
3541 that is back to the person who sent private message. The
3542 affected file lib/silcclient/silcapi.h and the
3543 lib/silcclient/client_prvmsg.c.
3545 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Fixed the private message sending in the Irssi SILC client,
3548 added local command KEY to the Irssi SILC client.
3550 Added key management and key agreement message formats to the
3551 irssi/src/fe-common/silc/module-formats.[ch].
3553 Added USERS (alias WHO) printing, server/router operator
3554 indication and LIST command printing to the module formats.
3556 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Fixed channel joining notify handling, cumode notify handling
3559 from Irssi SILC client.
3561 * Added SILC specific module-formats to the Irssi SILC client so
3562 that SILC specific message hilighting, colors etc is possible.
3563 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3565 Added channel mode, channel user mode, actions, notices,
3566 whois and whowas printing to the the module-formats.c.
3568 * Fixed a bug in channel deletion in the server. The channel
3569 is not left to the cache even if the channel founder auth mode
3570 is set when there are no users anymore on the channel. Affected
3571 file silcd/server.c.
3573 * The silc_net_localhost now resolves the entire hostname including
3574 the domain name. Affected file lib/silcutil/silcnet.c.
3576 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Changed the ask_passphrase client operation to be ascynchronous.
3579 It has now a completion callback and a context that the
3580 application must call after it has got the passphrase from
3581 the user. Affected files lib/silcclient/silcapi.h,
3582 lib/silcclient/protocol.c, lib/silcclient/command.c and
3585 Added SilcAskPassphrase callback that the application calls
3586 to deliver the passphrase to the library.
3588 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3589 The public key verification and especially a certificate
3590 verification is asynchronous procedure.
3592 Added new SILC_SKE_STATUS_PENDING status to indicate the
3593 request is pending and a callback will be called to finalize
3596 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3597 indicate that remote end did not send its public key (or
3598 certificate), even though we require it. Added check for this
3599 condition in the SKE. This was a security bug, now fixed.
3601 Defined new SilcSKEVerifyCbCompletion callback that is called
3602 when the verification process is completed.
3604 The affected files lib/silcske/silcske_status.h and
3605 lib/silcske/silcske.[ch].
3607 * Changed the verify_public_key client operation to be async
3608 as well. Defined SilcVerifyPublicKey callback that is used to
3609 indicate the success of the public key verification process.
3611 Changed the server and client to use the new async client
3614 * Changed the Irssi SILC client's internal scheduler to be called
3615 twice as many times as it used to be. As a result the client
3616 should be a bit faster now. Affected file is
3617 irssi/src/silc/core/silc-core.c.
3619 * Added support to Irssi SILC client of asynchronous public key
3620 verification and passphrase inquiry. Affected file is
3621 irssi/src/silc/core/silc-core.c.
3623 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Do not say "You have left channel %s" in client library.
3626 Moved it to the application. Affected files are
3627 lib/silcclient/command.c and silc/client_ops.c.
3629 * Fixed silc_client_get_clients. Command context was not
3630 duplicated and was freed memory in the callback. Affected
3631 file lib/silcclient/idlist.c.
3633 * Do not say "you are now talking..." on JOIN command in the
3634 client library. The appliation must handle it.
3636 * Do not say ".. changed topic to" in command reply in the
3637 client libary. The application must handle it.
3639 * Fixed TOPIC command sending in the client library.
3641 * Fixed a memory leak in silc_client_command_free in the file
3642 lib/silcclient/command.c.
3644 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Imported a modified version of Irssi client to the source tree.
3647 The Irssi will be used to create a new client called
3648 Irssi SILC. Imported to irssi/.
3650 Added silc_core_init_finish function to the Irssi. Affected
3651 file irssi/configure.in.
3653 A lot changes in the Makefile.ams around the irssi tree.
3655 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Do not rehash if the new size is same as the old size of the
3658 hash table, in the silc_hash_table_rehash*. The affected file
3659 lib/silcutil/silchashtable.c.
3661 * Replaced hash_table_del_by_context calls from the server
3662 (when channel->user_list and client->channels) to the
3663 hash_table_del as it is sufficient and faster.
3665 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Added silc_hash_table_list, silc_hash_table_get and the
3668 SilcHashTableList structure to provide an alternative way to
3669 traverse the hash table. The affected files are
3670 lib/silcutil/silchashtable.[ch].
3672 * Changed the server's idlist routines to use the hash table
3673 routines to optimize the code.
3675 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Replaced the client entry's `channel' list and channel entry's
3678 `user_list' list to hash tables for optimized lookup. Changed
3679 the code to use the hash table interface around the code.
3680 Affected file lib/silcd/idlist.[ch].
3682 * Added `auto_rehash' boolean argument to the function
3683 silc_hash_table_alloc to indicate whether the hash table should
3684 auto-rehash when it thinks is appropriate time. It will
3685 increase the hash table size if the there is twice as much
3686 entries in the table than the size of the table, and will
3687 decrease the size if there are twice as less entries than
3688 the size of the table.
3690 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3694 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * silc_idcache_purge_by_context deletes the entry now by context
3697 as it is supposed to do. Affected file lib/silccore/idcache.c.
3699 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3700 client is not anymore valid (WHOWAS givens the info) and not
3701 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3703 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Removed the `data' and `data_len' arguments from the ID Cache
3706 interfaces and added `name' argument. ID Cache does not handle
3707 anymore the binary data only a names associated with given ID.
3709 * When hashing a Client ID with silc_hash_id the entire ID is
3710 not hashed anymore, instead only the hash of the Client ID is
3711 hashed. This way we can access the Client ID from the cache
3712 with Client ID but with the hash of the ID (which is a hash of
3713 the nickname) as well without any difference in performance.
3715 Added also silc_idcache_find_by_id_one_ext to do one on one
3716 searching when we have the actual ID. Added also function
3717 silc_hash_client_id_compare. The affected files are
3718 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3720 * When hashing the name associated with a ID it is always done
3721 in lowercase. This way we can access the cache without worrying
3722 about case-sensitivity, even though, for example nicknames are
3725 * Fixed a bug in server with channel message sending. It put
3726 wrong ID type as destination ID. The affected file
3727 silcd/packet_send.c.
3729 * silc_idcache_del_by_context now deletes from all hash tables
3730 by context. Affected file lib/silccore/idcache.c.
3732 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Changed the client library to use the new ID Cache interface.
3735 Changes around the source tree.
3737 * Added silc_hash_table_rehash_ext to rehash with specific
3738 hash function. Affected file lib/silcutil/silchashtable.[ch].
3740 * Added silc_hash_string_compare to compare two strings in the
3741 hash table. Affected file lib/silcutil/silcutil.[ch].
3743 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Added new function silc_idcache_del_by_context into the
3746 lib/silccore/idcache.[ch].
3748 * Changed the server's ID list routines to use the new ID Cache
3749 interface. Changes around the source tree.
3751 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Added silc_hash_table_del[_by_context]_ext functions in to the
3754 lib/silcutil/silchashtable.[ch].
3756 Removed silc_hash_table_find_all* routines and added new
3757 silc_hash_table_find_foreach to replace them.
3759 Added silc_hash_table_replace_ext function as extended
3760 replacing function. Separated the simple hash table interface
3761 from the extended hash table interface in the file
3762 lib/silcutil/silchashtable.h.
3764 * Fixed minor bugs and changed it to use some of the new
3765 hash table functions in lib/silccore/idcache.c
3767 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Added new function silc_hash_table_find_all to return all keys
3770 in the hash table by the specified key. As the hash table is
3771 collision resistant it also makes it possible to have several
3772 duplicate keys in the hash table. This function may be used to
3773 find all of the keys from the hash.
3775 Added user_context arguments to the SilcHashFunction,
3776 SilcHashCompare and SilcHashDestructor to deliver user specified
3779 Added new fuctions silc_hash_table_find[_all]_ext to do
3780 extended lookup with specified hash and compare functions and
3781 specified user contexts.
3783 Added new function silc_hash_table_add_ext to add the key
3784 with specified hash function and user context.
3786 Added new function silc_hash_table_foreach to traverse all
3787 entrys in the hash table. Added SilcHashForeach callback
3790 Added new function silc_hash_table_del_by_context to delete
3791 the entry only if the context associated with the key matches.
3793 Affected files are lib/silcutil/silchashtable.[ch].
3795 * Removed silc_hash_[server/client/channel]_id and added just
3796 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3797 silc_hash_id_compare to compare two ID's using as the hash table
3798 comparison function. Added also silc_hash_data to hash
3799 binary data and silc_hash_data_compare to compare it.
3801 * Removed silc_idlist_find_client_by_hash as it is not needed
3802 anymore. Affected file silcd/idlist.[ch].
3804 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3805 to use internally the SilcHashTable. The new ID Cache is a lot
3806 faster than the old one. Some of the ID Cache interface was also
3807 rewritten and obsolete and stupid functions were removed.
3809 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Added entry_count field to the SilcHashTable to keep the number
3812 of the entries in the table. Implemented the function
3813 silc_hash_table_rehash. Added new function
3814 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3816 Fixed a minor bug in silc_hash_table_free.
3818 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3819 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3820 into the lib/silcutil/silcutil.[ch].
3822 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Implemented a collision resistant hash table into the
3825 lib/silcutil/silchashtable[ch]. See the header and the source
3826 for the SilcHashTable API.
3828 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Merged dotconf version 1.0.2 into lib/dotconf.
3832 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Do not compile anything in lib/silcsim/* if the SIM support
3835 is not enabled. The tree should now compile without problems
3838 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Compiled the SILC under cygwin. Compiled and tested briefly
3841 without problems. More tests needed. The SIMs didn't compile
3844 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3846 * Fixed possible crash in silc_get_username in the
3847 lib/silcutil/silcutil.c.
3849 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Fixed a va_arg in silc/client_ops.c.
3853 * Oops, RC5 routines were named AES and caused some problems
3854 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3856 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Added new SilcIDIP structure into the lib/silccore/id.h and
3859 replaced the old `ip' fields from all SILC ID's to that type.
3860 This is a step towards IPv6 support.
3862 The silc_id_get_len takes now the ID as an extra argument.
3863 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3864 both IPv4 and IPv6 based ID's.
3866 The affected files are lib/silccore/id.[ch] and other files
3867 around the tree using these routines.
3869 * Removed the ID length arguments in server from various
3870 silc_server_send_notify_* routines -> they are not needed
3873 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Fixed memory leak in silc_encode_pem_file in the file
3876 lib/silcutil/silcutil.c.
3878 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Check minor version as well in the SKE. Affected files are
3881 silcd/protocol.c and lib/silcclient/protocol.c.
3883 * Added --identifier option to the server so that an identifier
3884 can be when creating the public key for the server. Affected
3885 file is silcd/silcd.c.
3887 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3888 lib/silccrypt/silcpkcs.c.
3890 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Register default ciphers and stuff when using -C option with
3893 the server. Affected file sildc/silcd.c.
3895 * Put back the servers public key filename format, it is better
3896 than the new one. For now, the client keys are saved with the
3897 new filename format. The affected file silc/client_ops.c.
3899 * Implemented the Cipher API for the rest of the ciphers that
3900 did not implement it or implemented it the wrong way.
3902 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3904 * Register default ciphers and stuff when using the -S option
3905 in the client. Affected file silc/silc.c. Same also when
3906 creating new key pair with -C option.
3908 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Fixed the silc_verify_public_key client operation function to
3911 save the public keys differently. The fingerprint is now
3912 used as filename and not the hostname. This way also the
3913 client keys are saved uniquely and not with hostnames. The
3914 affected file is silc/client_ops.c.
3916 * Trimmed the silc_hash_fingerprint function to remove extra
3917 whitespaces from the end of the fingerprint. The affected
3918 file is lib/silccrypt/silchash.c.
3922 * Added silc_cipher_register_default function to register all
3923 default ciphers. It can be used when configuration files
3924 does not exist and the application does not want any specific
3925 ciphers in any specific order.
3927 The SilcDList is now used as silc_cipher_list dynamically
3928 allocated cipher list. Removed the static list all together
3929 and now all ciphers must be allocated to the dynamic list.
3930 The silc_cipher_alloc routine was changed to check only the
3933 All silc_cipher_* routines that used to return int returns
3936 The affected files lib/silccrypt/silccrypt.[ch].
3938 * The same thing was done to silc_hash_* as for silc_cipher_*
3939 routines. Affected files lib/silccrypt/silchash.[ch].
3941 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3942 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3943 Added also silc_pkcs_[un]register[_default] functions.
3944 Removed the data_context from the PKCS API.
3946 * Added silc_hmac_register_default function to register default
3947 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3948 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3949 to unregister all hmacs at once.
3951 * Register the default ciphers, hash functions, PKCSs and HMACs
3952 if client's configuration file does not exist. The affected
3955 * The client did not load the hash functions from the SIM
3956 modules at all. Added support for this. Affected file is
3957 silc/clientconfig.c.
3959 * When decoding public key with silc_pkcs_public_key_decode, check
3960 the supported algorithm only if PKCS are registered. Affected
3961 file lib/silccrypt/silcpkcs.c. The same was done with the
3962 silc_pkcs_private_key_decode.
3964 * Fixed the SILC List routines to keep the list always in order.
3965 It used to change the list's order when traversing the list but
3966 not it preserves the order. Affected file lib/trq/silclist.h.
3968 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Added the client library to use the SilcSocketConnection's
3971 reference counter (by silc_socket_dup) to prevent the bug that
3972 the socket object may be freed underneath async operation.
3974 * The name resolv library checking fixes in the configure.in.pre.
3977 * Created new version of the protocol drafts for future
3978 development. The -03 drafts are the ones that will be changed
3979 in the trunk now and the -02 will remain as they are.
3981 * Send list of CUMODE notifys to the router when announcing
3982 the channel users to the router. Affected file silcd/server.c.
3983 If the router receiving channel founder CUMODE for a channel
3984 that already has channel founder it will send CUMODE notify
3985 to the sender to remove the channel founder rights from the
3986 announced client. Affected file silcd/packet_receive.c.
3988 * The CUMODE notify may now use Server ID as well as the entity
3989 who changes the mode. Updated protocool specs.
3991 * Updated INSTALL and README files.
3993 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * New web pages in the http://silc.pspt.fi. The pages was
4000 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Implemented the [DenyConnectin] config section in the server.
4003 Added silc_server_config_denied_conn to check whether incoming
4004 connection is denied. Affected file silcd/serverconfig.[ch].
4006 * Do not check the ports when checking the incoming configuration
4007 data if the port is 0, meaning any. Affected file is
4008 silcd/serverconfig.c.
4010 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Fixed buffer overflow in silc_string_compare in the file
4013 lib/silcutil/silcutil.c.
4015 * Fixed double free in silc_server_command_leave in the file
4018 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Fixed the version checking in the server. Affected file is
4023 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Fixed the configuration data fetching when accepting new
4026 connections in the server. Affected file silcd/server.c.
4028 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Added `sender_entry' argument to the function
4031 silc_server_packet_relay_to_channel so that we can check
4032 whether some destination actually belongs to the same route
4033 the sender belongs (ie, we must not resend the packet to the
4034 sender). Affected file silcd/packet_send.[ch].
4036 * Added `servername' field to the SilcClientEntry in the server
4037 to hold the name of the server where client is from. Affected
4038 file is silcd/idlist.h.
4040 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Moved the channel message encrypting in the router betwen
4043 router connections from silc_server_channel_message to the
4044 silc_server_packet_relay_to_channel since we want to check
4045 whether we have anybody channel before encrypting anything.
4046 Affected files silcd/packet_[receive/send].c.
4048 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Fixed the [AdminConnection] server config section to support
4051 multiple entries. Affected file silcd/serverconfig.c.
4053 * Added support into the server to check the validity of the
4054 incoming connection before executing any KE or authentication
4057 * The connection configuration is now saved to the KE and
4058 connection auth protocol contexts and not fetched anymore in
4059 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4061 * The local hosts listenning address and port is also resolved
4062 now when starting the server. We want to have the socket object
4063 to include the real address and port for the listener. Added
4064 new function silc_net_check_local_by_sock into the files
4065 lib/silcutil/silcnet.[ch].
4067 * Fixed a broadcast bug in server -> do not broadcast if we
4070 * Fixed a routing bug. Do not route broadcast packets ever.
4071 Broadcast packets must be processed always and not routed since
4072 they may be destined to some other host than yourself and thus
4073 would get routed without no good reason. Affected file is
4076 * Added function silc_server_config_is_primary_route to check
4077 whether primary router connection has been configured (a router
4078 configuration that we are initiating). If there is not, we
4079 will assume that there is only two routers in the SILC network
4080 and we will use the incoming router connection as our primary
4081 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4083 * Changed the order of the broadcasting. Broadcast _after_ the
4084 packet has been processed not before. Affected file is
4087 * Fixed a [ClientConnection] parsing bug. The port was never
4088 parsed correctly thus resulting to port 0. Affected file
4089 silcd/serverconfig.c.
4091 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4092 argument and did not set the broadcast packet flag. Affected
4093 file silcd/packet_send.c. Fixed same bug in the function
4094 silc_server_send_notify as well.
4096 * If we receive NEW_ID packet for our own ID in the server, ignore
4099 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Removed the nickname from the Private Message Payload.
4104 Updated the code and the protocol specs.
4106 * Updated protocol specs for submitting to the IETF.
4108 * Tweaked the Random Number Generator a bit. Affected file
4109 lib/silccrypt/silcrng.c. Exported a new function
4110 silc_rng_[global]_add_noise which can be used to add more
4113 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * Do not parse packets with different timeout when protocol
4116 is active -> may cause problem with rekey. Affected file
4119 * When server receives signoff notify it must not create
4120 new channel key if the client is on any channels since the
4121 sender of the signoff notify will create it.
4123 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Added printing of error messages during SKE protocol from the
4126 failure packet sent by server during SKE. Affected file
4129 * Removed the client's failure_callback handling with timeout
4130 and handle it immediately when received.
4132 * The SKE library returned wrong type in SUCCESS and FAILURE
4133 packets. They must be 32 bit MSB not 16 bit MSB.
4135 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Ok, rewrote the logic of the re-key and now it seems to work.
4138 I tested it on high traffic with frequent re-keys without
4139 problems. Added hmac_receive (and renamed hmac to hmac_send)
4140 in SilcClientConnection in lib/silcclient/client.h and
4141 in SilcIDListData in silcd/idlist.h. Also, removed the
4142 SilcPacketParserContext's cipher and hmac fields as they are
4143 not needed anymore and actually caused some problems when
4144 the ciphers and hmac's changed underneath the packet parser.
4146 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * If re-key protocol is active then process the incoming packets
4149 synchronously since we must assure that icoming packets encrypted
4150 with the old key is processed before the new keys is set to
4151 use. This is true other packets than for REKEY packets.
4152 Affected file silcd/server.c. The same was done to client library
4153 as well, affected file lib/silcclient/client.c.
4155 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Fixed bug in client and server to accept the force send if
4158 the packet is send from silc_[server/client]_packet_process
4159 function. Otherwise the packets are never delivered, oops.
4161 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Disable force sending of packets when REKEY protocol is active.
4164 We must assure that no packet is sent directly when rekey is
4165 performed. All packets must be sent through packet queue.
4166 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4167 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4168 function is silc_[server/client]_packet_send_real to check
4171 * Replaced the SIM paths from example config files to
4172 /usr/local/modules. Also, make install creates now
4173 /usr/local/silc/logs directory to hold all the SILC server
4176 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Made the configure.in.pre work on Solaris. Patch by salo.
4180 * Made all ciphers compatible with non-x86 machines. Defined
4181 CBC mode macros into lib/silccrypt/ciphers_def.h.
4183 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Fixed the make install.
4187 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * When MAC computation fails the silc_packet_decrypt returned 0
4190 even though it was supposed to return -1. Fixed this. The
4191 affected file is lib/silccore/silcpacket.c.
4193 * Do not replace the config files in /etc/silc (in make install)
4194 if they already exist. Affected file ./Makefile.am.
4196 * Do not send re-key packets immediately but through packet queue.
4197 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4199 * Changed silc_net_check_host_by_sock to return FALSE if the
4200 IP/DNS could not be resolved. Though, it returns the IP address
4201 now even if it could not resolve it (but returns also FALSE).
4202 Affected file lib/silcutil/silcnet.[ch].
4204 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Added silc_pkcs_decode_identifier to decode the public key's
4207 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4208 Added also silc_pkcs_free_identifier. Added also new context
4209 SilcPublicKeyIdentifier.
4211 * Added -S option to the silc client. It is used to dump the
4212 contents of the specified public key file.
4214 * Changed the PKCS api to return the public key length when
4215 setting the public key.
4217 * Fixed a fatal bug in the public and private key file loading.
4218 Affected file lib/silccrypt/silcpkcs.c.
4220 * Execute the packet parsing for client with zero (0) timeout
4221 if the protocol is active. Affected file silcd/server.c.
4223 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Made the key generation options to the silcd program. Added
4226 -C option, equivalent to client's option.
4228 * Added new [ServerKeys] config section to the server. It
4229 configures the server's public and private key.
4231 * Defined generic Public Key Payload into the protocol
4232 specification to send specific type of public keys and
4235 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4236 public key or certificate.
4238 * Implemented the GETKEY command to the server and to the
4239 client library and on user interface.
4241 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Made preliminary `make install' work.
4245 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added SilcServerRekey context into silcd/idlist.h.
4249 * Added the PFS support as defined in the specification to the
4250 SKE protocol. Affected files lib/silcske/*.c.
4252 * Added `ske_group' field to the SilcServerRekey context to hold
4253 the number of the SKE group that is used with PFS in re-key.
4254 Affected file silcd/idlist.h.
4256 * Added PFS re-key support to the server. Affected file is
4259 * Added silc_protocol_cancel to cancel execution of the next
4260 state of the protocol. Affected file is
4261 lib/silccore/silcprotocol.[ch].
4263 * Added the re-key support with and without PFS to the client
4264 library. Re-key is performed once in an hour, by default.
4266 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4267 Added silc_client_rekey_callback and silc_client_rekey_final.
4268 Affected files are lib/silcclient/protocol.[ch] and
4269 lib/silcclient/client.[ch].
4271 * Removed the `hmac_key' and `hmac_key_len' fields from the
4272 SilcClientConnection structure; not needed. Affected file is
4273 lib/silcclient/client.h.
4277 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Do not ask whether user wants to use the negotiated private key
4280 for private messages, just use it. Affected file is
4281 silc/local_command.c.
4283 * Added `send_enc_key' and `enc_key_len' fields to the
4284 SilcIDListData structure since they are needed in the re-key
4285 phase. Affected file is silcd/idlist.[ch].
4287 * Implemented the simple re-key protocol into the server.
4288 Affected files silcd/server.c and silcd/protocol.[ch]. The
4289 re-key will be performed once in an hour, by default.
4291 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4292 Added silc_server_rekey, silc_server_rekey_callback and
4293 silc_server_rekey_final.
4295 * Removed Tunneled flag from the protocol. Updated the code
4296 and the specifications.
4298 * Adde `pfs' field to the SilcIDListData to indicate whether
4299 the PFS is to be performed in the re-key. Affected file is
4302 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4305 int64 of at least the xintXX size. If void * is less that 4
4306 bytes uint32 * will be used. Defined bool as boolean.
4308 * Changed _ALL_ unsigned long and unsigned int to uint32,
4309 unsgined short to uint16 in the source tree.
4311 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4312 not handle clients that has entry->data.registered == FALSE.
4313 They are not in the network anymore. Affected file is
4316 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Implemented the sending of the SERVER_SIGNOFF notify in the
4319 server. Affected file is silcd/server.c.
4321 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4322 Added also silc_notify_payload_encode_args into the
4323 lib/silccore/silcnotify.[ch].
4325 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4326 Affected file silcd/packet_receive.c.
4328 * Implemented the SERVER_SIGNOFF notify handling in the client
4329 library. Affected file lib/silcclient/client_notify.c. Also,
4330 implemnted the printing of the SERVER_SIGNOFF info to the
4331 application. Affected file silc/client_ops.c.
4333 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4334 if the deleting was successful. Affected file silcd/idlist.[ch].
4336 * Added support for public key authentication in the connection
4337 authentication protocol in the client library. Affected file
4338 lib/silcclient/protocol.c.
4340 * Changed the server's silc_idlist_get_clients_by_* interface
4341 to support already allocated array so that new entries may be
4342 added to pre-allocated array. Affected file silcd/idlist.[ch].
4343 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4344 and command replies.
4346 * All command reply functions in the server now calls the
4347 pending command callback even if error occured. This way the
4348 error will be delivered to the client as well. Affected files
4349 silcd/command.c and silcd/command_reply.c.
4351 * Fixed INFO command to return local server's info if no server
4352 was provided. Affected file lib/silcclient/command.c.
4354 * Removed RESTART command for good. Updated the code and the
4357 * Rewrote parts of the task system. It is a bit simpler now.
4358 Removed unsued task priorities. The affected files are
4359 lib/silcutil/silctask.[ch].
4361 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Moved the USERS printing from the library to the application.
4364 Affected files lib/silcclient/command.c and silc/client_ops.c.
4366 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Added channel key re-key support. The re-key is perfomed
4371 only by the router and is done once in an hour. Added `rekey'
4372 field to the SilcChannelEntry in the server. Affected files
4373 silcd/server.c and silcd/idlist.h.
4375 * Added silc_task_unregister_by_context into the file
4376 lib/silcutil/silctask.[ch].
4378 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Added SILC_UMODE_GONE mode to indicate when the client is not
4381 present in the SILC network. Added also support to the local
4382 command AWAY that will set this mode. Added support of showing
4383 "xxx is gone" in WHOIS command. The USERS command shows the
4384 gone status as well.
4386 * Fixed setting server and router operator privileges in the
4387 server's UMODE command. Affected file silcd/command.c.
4389 * Merged the SKE KE1 and KE2 payloads into one payload. The
4390 new KE payload is equivalent to the old KE2 payload.
4392 Cleaned up the SKE Start Payload parsing. It now uses the
4393 simple buffer unformatting to do the parsing. A lot faster
4396 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4397 to the SKE that is used to indicate whether both of the SKE
4398 parties should perform authentication. By default only the
4399 responder performs authentication. By setting this flag also
4400 the initiator must do authentication. By default it is unset
4401 since in normal SKE case, client to server connection, only
4402 the responder should do authentication. When doing SKE between
4403 two clients both should perform authentication. Updated the
4404 code and the protocol specs.
4406 * A little fix to IDENTIFY command in the server. Search the
4407 client first by hash not nickname. Affected file is
4410 * Fixed the silc_client_close_connection to support closing
4411 the client to client connections wihtout deleting too much
4412 data. Affected file lib/silcclient/client.c.
4414 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4415 are received if protocol used to be active but is not anymore
4416 the application would crash due to NULL pointer dereference.
4417 Affected files silcd/server.c and lib/silcclient/client.c.
4419 * Added `hash' field to the SilcClientConnection to include
4420 the hash function negotiated in the SKE protocol.
4422 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4423 to set the channel founder authentication data. A client can
4424 claim the founder rights later by providing the authentication
4425 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4426 This way the channel founder can regain the channel founder
4427 privileges even it is left the channel. This works only on
4428 local server and the client must be connected to the same
4429 server to be able to regain the founder rights. Updated the
4430 protocol specs accordingly.
4432 Added support to the CMODE command in the client to set the
4433 founder auth data. Read the README to see how to set it.
4435 Added support to the CUMODE command to claim the founder
4436 rights. Read the README to see how to do it.
4438 Added support for the founder authentication to the Channel
4439 Entry in the server. Affected file silcd/idlist.h.
4441 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4442 server's CMODE command. Affected file silcd/command.c.
4444 * Added the following new functions into lib/silccore/silcauth.[ch]:
4445 silc_auth_get_method and silc_auth_get_data.
4447 * The server now saves the remote hosts public key to the
4448 SilcIDListData pointer. Affected file silcd/protocol.c.
4450 * The normal server now does not remove the channel entry from
4451 the cache if the founder authentication data is set. It used
4452 to remove it if the founder was the last one on the channel on
4453 the server and left the channel. The auth data is saved and
4454 if the channel is re-joined later the old entry is used with
4455 the old auth data. Affected files silcd/command_reply.c and
4458 * Removed the `pkcs' field from the SilcIDListData structure
4459 in the server; it is not used. Affected file silcd/idlist.h.
4461 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Fixed packet processing on slow links. Partial packets were
4464 never re-processed because the incoming data buffer was cleared
4465 by the application. Application must not directly clear the
4466 sock->inbuf, the packet processing routines handle it. Fixed
4467 this in client library and in server.
4469 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Fixed the WHOIS and IDENTIFY send reply function to really
4472 check whether to send list or just one entry. Affected file
4475 * Cleaned up the LEAVE command's channel key distribution. The
4476 affected file silcd/command.c.
4478 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4479 can enforce the channel mode as well. In that case the ID
4480 includes the ID of the server. The code now enforces the
4481 mode change if the router have different mode than the server.
4483 * The notify client operation with CMODE_CHANGE notify can now
4484 return NULL client_entry pointer if the CMODE was not changed
4485 by client. Application must check for this.
4487 * Added <Server ID> argument to INFO command to support server
4488 info fetching by Server ID.
4490 * Added silc_server_announce_get_channel_users to get assembled
4491 packets of channel users of the specified channel. Affected
4492 file silcd/server.[ch].
4494 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4495 was freed underneath the ID Cache.
4497 * Re-announce clients when the server received CHANNEL_CHANGE
4498 notify from the router. Affected file silcd/packet_send.c.
4500 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4503 crashed since it did not handle the fact that there is no cipher
4504 called "3" and didn't check the error condition. Now fixed.
4506 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4507 flag. It can be used to send message requests.
4509 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Implemented the RESTART command in the client.
4513 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4514 notice type messages. Added notice printing to the user
4517 * The channel keys are not re-generated if the channel's mode
4518 is PRIVKEY, ie private key on the channel exists. Affected
4519 files silcd/server.c and silcd/command.c.
4521 * Fixed a little bug in channel message delivery when channel
4522 private keys are set in the server. Affected file is
4523 silcd/packet_send.c.
4525 * Changed the setting on channel->on_channel = TRUE from the
4526 silc_client_save_channel_key to the JOIN command reply. The
4527 key payload is not received if the private channel key is set.
4528 Affected file lib/silcclient/command_reply.c and the
4529 lib/silcclient/client_channel.c.
4531 * When the CMODE_CHANGE notify is sent and the channel private
4532 key mode is removed the channel key must be re-generated in
4533 other cells as well. Added this support for the router in the
4534 silcd/packet_receive.c.
4536 * Added new local command NOTICE to send notice message on
4537 channel. Affected file silc/local_command.[ch].
4539 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Added new local command ME to the client. It is used to send
4542 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4543 some action. Affected file silc/local_command.[ch].
4545 * Changed channel_message and private_message client operations
4546 to deliver the message flags to the application. Added also
4547 the `flags' arguments to the silc_client_send_channel_message
4548 and silc_client_send_private_message functions. Affected file
4551 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Redefined the Private Message Payload to support private message
4554 keys and to support the new private message flags. Updated
4555 the protocol specs. Flags makes it possible to have for example
4556 CTCP style messages.
4558 * Added new type SilcPrivateMessagePayload and defined an API
4559 for it in the lib/silcclient/silcprivate.[ch].
4561 * Tested private message private keys successfully. Tested the
4562 private message key set, unset and list commands with the new
4565 * Redefined the Channel Message Payload to include the channel
4566 message flags (equal with private message flags) to support
4567 for example CTCP style messages.
4569 * Defined some of the message (for channel and private message)
4570 flags. Updated the protocol specs and added the flags to the
4571 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4573 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added SilcKeyAgreementStatus type to the key agreement routines
4576 to indicate the current status and error if one occured.
4577 The status types are defined in the lib/silcclient/silcapi.h.
4579 * Added new local command KEY that is used to set and unset private
4580 keys for channels, set and unset private keys for private messages
4581 with remote clients and to send key agreement requests and
4582 negotiate the key agreement protocol with remote client. The
4583 key agreement is supported only to negotiate private message keys,
4584 it currently cannot be used to negotiate private keys for channels,
4585 as it is not convenient for that purpose.
4587 * Fixed a minor pending callback setting bug in the function
4588 silc_client_get_client_by_id_resolve, now the function works.
4589 Affected file lib/silcclient/idlist.c.
4591 * Added function silc_net_get_local_port to get local bound
4592 port by socket. Added to lib/silcutil/silcnet.[ch].
4594 * Added `sockets' and `sockets_count' fields to the SilcClient
4595 object. They hold the sockets of the listenning sockets in
4596 the client. Listenning sockets may be for example the key
4597 agreement server. Affected file lib/silcclient/client.[ch].
4598 Added functions the silc_client_add_socket and the
4599 silc_client_del_socket. They are exported to the application
4602 * Added ~./silc/clientkeys to support other client's public keys.
4604 * Renamed verify_server_key client operation to verify_public_key
4605 and added one argument to indicate the type of the connection
4606 (server, client etc.).
4608 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Added silc_server_connection_auth_request to handle the
4611 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4612 silcd/packet_receive.[ch].
4614 * Added silc_server_send_connection_auth_request into the
4615 silcd/packet_send.c to send the connection auth request packet.
4617 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4620 * Fixed the public key authentication in responder side in the
4621 server. The `auth_data' pointer includes the SilcPublicKey
4622 not the path to the public key. Affected file silcd/protocol.c.
4624 * Implemented the public key authentication in the initiator side
4625 in the server. Affected file silcd/protocol.c.
4627 * Removed the [RedirectClient] config section from the server
4628 configuration. Is not needed and I don't want to implement it.
4630 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Cleaned up the CMODE command in the server. It now works
4633 correctly and supports all the modes defined in the protocol.
4634 Affected file is silcd/command.c.
4636 * Added `hmac_name' field to the SilcChannelEntry in the server
4637 to hold the default HMAC of the channel. It can be set when
4638 creating the channel (with JOIN command). Affected files
4641 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4642 type to indicate the change of the current cipher and hmac
4643 on the channel. Client can safely ignore the <cipher> argument
4644 (if it chooses to do so) since the CHANNEL_KEY packet will
4645 force the channel key change anyway. The <hmac> argument is
4646 important since the client is responsible of setting the new
4647 HMAC and the hmac key into use.
4649 * Fixed the CMODE command in the client library as well.
4651 * Tested CMODE command in router environment successfully.
4653 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Show the version of the remote client (or server) when connecting
4656 to the server. It is logged to the log file. Affected file
4657 is silcd/protocol.c.
4659 * Fixed the KILLED notify handling in the client library. The
4660 client must be removed from all channels when receiving the
4663 Also, do not remove the client entry when giving the KILL
4664 command but when the KILLED notify is received.
4666 * Removed silc_idlist_find_client_by_nickname from the server.
4667 Not needed anymore. Affected files silcd/idlist.[ch].
4669 * Implemented the CHANNEL_CHANGE notify type handling to the
4670 server. Affected file silcd/server.c.
4674 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added silc_server_send_notify_invite to send the INVITE
4677 notify between routers.
4679 * Implemented the INVITE command correctly to the server.
4681 * Implemented the INVITE notify type handling in the server.
4683 * Implemented the INVITE command to the client library and on the
4686 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Added function silc_server_get_client_resolve to find the
4689 client entry by ID from all ID lists and then resolve it
4690 (using WHOIS) if it cannot be found. Affected file is
4693 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Implemented the BAN command to the client library.
4697 * The JOIN command in the server now checks the invite list
4700 * Changed the silc_command_reply_payload_encode_va and the
4701 silc_command_payload_encode_va to support that if argument is
4702 NULL it ignores and checks the next argument. Affected file
4703 lib/silccore/silccommand.c.
4705 * Added silc_server_send_notify_ban to send the BAN notify
4706 type between routers.
4708 * Chaned the silc_notify_payload_encode to support that if
4709 argument is NULL it ignores and checks the next argument.
4710 Affected file lib/silccore/silcnotify.c.
4712 * Tested ban lists in router environment successfully.
4714 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Implemented BAN command to the server, in silcd/command.[ch].
4718 * Removed the BAN and INVITE_LIST modes from the CMODE command
4721 * Added function silc_string_match to regex match two strings.
4722 Affected files lib/silcutil/silcutil.[ch].
4724 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Redefined parts of the SilcChannelEntry in the server to support
4727 the new ban and invite lists.
4729 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Redefined the INVITE command. The same command can be used to
4732 invite individuals to the channel but also to manage the invite
4733 list of the channel (to add to and remove from the invite list).
4734 Updated the protocol specs.
4736 * Added new command SILC_COMMAND_BAN that can be used to manage
4737 the ban list of the channel. Updated the protocol specs.
4739 * Removed the channel modes: the SILC_CMODE_BAN and the
4740 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4741 in the CMODE command. The equivalent features are now available
4742 using INVITE and BAN commands. Updated the protocol specs.
4744 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4745 in the network about change in the current ban list. The notify
4746 type is not used by the client.
4748 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4749 support the invite lists.
4751 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Added new function silc_string_regexify that converts string
4754 including wildcard characters into regex string that can
4755 be used by the GNU regex library. Added into the file
4756 lib/silcutil/silcutil.[ch].
4758 Added silc_string_regex_combine to combine to regex strings
4759 into one so that they can be used as one regex string by
4760 the GNU regex library. Added into the file
4761 lib/silcutil/silcutil.[ch].
4763 Added silc_string_regex_match to match two strings. It returns
4764 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4766 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Imported GNU regex to the soruce tree into lib/contrib.
4769 Fixed some compiler warning from the regex.c.
4771 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Fixed MOTD command in the server to work in router environment.
4775 * Fixed the MOTD command in the client library to support
4776 the server argument in the command.
4778 * Added `nickname_len' argument to the silc_idlist_add_client
4779 in the server, as the `nickname' argument may be binary data
4782 * Added silc_idlist_get_channels to return all channels from
4785 * Implemented LIST command to the server. Affected file is
4788 * Implemented the LIST command to the client library and on the
4791 * Added [<user count>] argument to the LIST command reply.
4792 With private channels the user count is not shown.
4794 * Updated TODO and README.
4796 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * The client entry's data.registered must be TRUE even with
4799 global client entry on global client list. The data.registered
4800 is used to check whether the client is anymore in the network,
4801 for example with WHOWAS command so it must be valid.
4803 * Fixed the WHOWAS command in the server. It now actually works
4804 in router environment. Added function into silcd/command_reply.c
4805 silc_server_command_reply_whowas_save.
4807 * Added silc_idlist_purge function to the silcd/idlist.c
4808 to periodically purge the ID Cache.
4810 * Fixed INFO command in the server. It works now in router
4811 environment. Added <server name> argument to the INFO command
4812 reply. Updated the protocol specs.
4814 * Fixed minor bug in silc_idcache_purge to not purge if the
4815 expire value is zero.
4817 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4818 they were buggy because of the WHOWAS information.
4820 * Fixed local command MSG to handle the async resolving of
4821 the remote client properly. It used to fail the first MSG.
4822 Affected file silc/local_command.c.
4824 * Added `data_len' field to SilcIDCache context.
4826 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Update TODO. Todo in commands in the server.
4830 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4833 used by routers as broadcast packet to inform other routers
4834 about the changed user mode.
4836 Implemented the notify handling in the server. Affected file is
4837 silcd/packet_receive.c. Added the function
4838 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4840 * Added new generic Channel Payload and deprecated the New Channel
4841 Payload. The New Channel Payload is now the generic Channel
4844 * Added new argument `mode' to the silc_server_send_new_channel
4845 as it is required in the Channel Payload now.
4847 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4848 and created a new and real SilChannelPayload to represent the
4849 new generic Channel Payload. Implemented the encode/decode
4850 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4852 * Added silc_server_get_client_channel_list to return the list
4853 of channels the client has joined for WHOIS command reply.
4854 Affected file silcd/server.[ch].
4856 * Implemented the channel list sending in the WHOIS command reply
4857 in server and in the client.
4859 Implemented the channel list displaying on the user interface
4860 as well. Affected file silc/client_ops.c.
4862 * Added silc_channel_payload_parse_list to parse list of Channel
4863 Payloads. It returns SilcDList list of SilcChannelPayloads.
4864 Client for example can use this function to parse the list of
4865 channels it receives in the WHOIS command reply. The caller
4866 must free the list by calling silc_channel_payload_list_free.
4867 Affected files lib/silccore/silcchannel.[ch].
4869 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Added one new argument <user mode> to the WHOIS command reply
4872 to return the mode of the user in SILC. Updated the protocol
4875 Implemented it to the server and client.
4877 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Fixed the mode printing on the user interface on joining.
4880 Affected file silc/client_ops.c.
4882 * Implemented the UMODE command and user modes in general to the
4883 client library and to the user interface.
4885 * Implemented the UMODE command to the server.
4887 * The server now sends UNKNOWN_COMMAND error status if client sends
4888 unknown command. Affected file silcd/command.c.
4890 * All server commands now handle the command identifier the right
4891 way when sending the command reply to the client. The client can
4892 use to identify the command replies with the identifier.
4894 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4896 * Added silc_server_get_client_route to resolve the route to
4897 the client indicated by the client ID. Affected file is
4900 * Added silc_server_relay_packet as general function to relay
4901 packet to arbitrary destination. This deprecates functions
4902 like _send_private_message_key, _relay_notify etc. Affected
4903 file is silcd/packet_send.[ch].
4905 Removed silc_server_send_key_agreement,
4906 silc_server_send_private_message_key and
4907 silc_server_packet_relay_notify functions from the file
4908 silcd/packet_send.[ch].
4912 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4913 server. Affected file silcd/packet_receive.[ch].
4915 * Implemented the KILL command to the client. Implemented the
4916 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4917 Affected files lib/silcclient/command[_reply].c and
4918 lib/silcclient/client_notify.c. Implemented the KILL notify
4919 printing in the user inteface.
4921 * Fixed a lot silc_parse_nick memory leaks from the client
4922 library in the file lib/silcclient/command.c.
4924 * Changed the silc_server_send_notify_on_channels's `sender'
4925 argument from SilcSocketConnection to SilcClientEntry to
4926 check the sender as entry and not as connection object and not
4927 to send to the client provided as argument. The affected file
4928 is silcd/packet_send.[ch].
4930 * The notify packets that are destined directly to the client used
4931 to not to be processed by the server. Now changed that and the
4932 server processes all notify packets. After relaying the packet
4933 to the client the notify packet is processed in the server.
4935 * The silc_server_free_client_data now checks whether there is
4936 pending outgoing traffic for the client and purges the data to
4937 the network before removing the client entry.
4939 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4942 an client is killed from the SILC Network. Updated the protocol
4945 Added new function silc_server_send_notify_killed to the
4946 silcd/packet_send.[ch].
4948 * Added function silc_server_packet_relay_notify to relay notify
4949 packets that are destined directly to a client. In this case
4950 the server does not process the notify packets but merely relays
4951 it to the client. Affected file silcd/packet_send.[ch].
4953 Added also silc_server_packet_process_relay_notify to check
4954 whereto relay the notify. Affected file is
4955 silcd/packet_receive.[ch].
4957 * Implemented the KILL command to the server.
4961 * Added the backup schema desgined last fall to the protocol
4962 specs for everyone to see. The specification is in the
4963 *-spec-xx.txt draft and the packet type definitions for the
4964 backup routers is in *-pp-xx.txt draft. Thusly, added also
4965 new packet type SILC_PACKET_CELL_ROUTERS.
4967 * A big security problem in the implementation discovered. The
4968 signoff of an client did not cause new channel key generation
4969 which it of course should've done. The channel keys must be
4970 always re-generated when client leaves (or signoffs) the channel.
4971 The silc_server_remove_from_channels funtion now handles
4972 the channel key re-generation.
4974 * Added `sender' argument to the silc_server_send_notify_on_channels
4975 to not to send the client provided as argument. Affected file
4976 silcd/packet_send.[ch].
4978 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Implemented OPER and SILCOPER commands into the server and
4983 * Added silc_auth_verify and silc_auth_verify_data to verify
4984 the authentication directly from the authentication payload.
4985 It supports verifying both passphrase and public key based
4986 authentication. Affected file lib/silccore/silcauth.[ch].
4988 * Added `hash' field to the SilcIDListData structure. It is the
4989 hash negotiated in the SKE protocol. Affected file is
4992 * Slight redesigning of the SilcAuthPayload handling routines.
4993 Do not send SilcPKCS but SilcPublicKey as argument.
4995 * Implemented the public key authentication support to the
4996 serverconfig. The public key is loaded from the provided path
4997 and saved as authentication data to void * pointer. Thus,
4998 changed the unsigned char *auth_data to void *auth_data;
5000 * Fixed SHUTDOWN command to send the reply before the server
5001 is shutdown. :) Affected file silcd/command.c.
5003 * Fixed fatal bug in CONNECT command. The hostname was invalid
5004 memory and server crashed. Affected file silcd/command.c.
5006 * Fixed fatal bug in CLOSE command. The server_entry became
5007 invalid but was referenced later in the command. Affected file
5010 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Fixed fatal bug in failure packet handling. Server ignored
5013 the failure and thus crashed when it came.
5017 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5020 that the command may be executed only once in (about) 2 seconds.
5021 The old SILC_CF_LAG flag is same but allows command bursts up
5022 to five before limiting.
5024 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5025 server code. Various commands now includes the CF_LAG_STRICT
5026 flag to disallow any kind of miss-use of the command.
5028 * Fixed the silc_buffer_unformat to not to allocate any data
5029 if the length of the data is zero. It used to allocate the
5030 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5032 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Changed the format of AdminConnection configuration section
5035 in the server. Added username of the admin to the format.
5036 Affected files silcd/serverconfig.[ch].
5038 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5039 to return admin configuration data by host, username and/or
5042 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Implemented WHOWAS command to the server. Added the functions:
5046 silc_server_command_whowas_parse,
5047 silc_server_command_whowas_send_reply,
5048 silc_server_command_whowas_from_client and
5049 silc_server_command_whowas_from_server
5051 * Added <Client ID> argument to the WHOWAS command reply. Updated
5052 the protocol specs accordingly.
5054 * Implemented WHOWAS command and command_reply to the client
5057 Implemented the WHOWAS printing on the user interface.
5059 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Added new argument to the WHOWAS command reply, the real name.
5062 It is an optional argument. Updated the protocol specs.
5064 * Added SilcIDCacheDestructor callback that is registered when
5065 the SilcIDCache is allocated. The callback is called when
5066 an cache entry in the ID Cache expires, or is purged from the
5067 cache. Added into lib/silccore/idcache.[ch].
5069 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5070 to destruct the client entries when the cache entry expires.
5071 Other ID Cache's in server and in the client library ignores
5074 * If the ID Cache entry's `expire' field is zero then the entry
5075 never expires. Added boolean `expire' argument to the
5076 silc_idcache_add function in the lib/silccore/idcache.[ch].
5077 If it is TRUE the default expiry value is used.
5079 * Added silc_server_free_client_data_timeout that is registered
5080 when client disconnects. By default for 5 minutes we preserve
5081 the client entry for history - for WHOWAS command.
5083 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Added support to the server to enforce that commands are not
5086 executed more than once in 2 seconds. If server receives
5087 commands from client more frequently, timeout is registered
5088 to process the commands. Affected file silcd/command.c.
5089 Added new function silc_server_command_process_timeout.
5091 * Changed NICK_NOTIFY handling in client library to check that
5092 if the client's nickname was changed, so there is no need to
5093 resolve anything from the server.
5095 * Removed error printing from the WHOIS and IDENTIFY commands.
5096 If error occurs then it is ignored silently in the client library.
5097 The application, however, may map the received error to
5098 human readable error string. The application currently maps
5099 the NO_SUCH_NICKNAME error to string.
5101 * Made the command status message public to the application. Moved
5102 them from lib/silcclient/command_reply.c to
5103 lib/silcclient/command_reply.h. The application can map the
5104 received command status to the string with the
5105 silc_client_command_status_message function.
5107 * Added check to the server to check that client's ID is same
5108 as the Source ID in the packet the client sent. They must
5111 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Added dist-bzip hook to the Makefile.am to make bzip2
5114 compressed distributions.
5116 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Server now enforces the maximum length for the nickname and
5119 the channel as protocol specification dictates. 128 bytes for
5120 nickname and 256 bytes for channel name.
5122 * Moved the WHOIS printing to the application. The client libary
5123 does not print out the WHOIS information anymore, the application
5124 must do it. Renamed silc_client_command_reply_whois_print to
5125 the silc_client_command_reply_whois_save.
5127 The client's idle time is also sent to the application now, and
5128 the idle is shown on screen.
5130 * Added silc_client_command_reply_identify_save to save the
5131 received IDENTIFY entries.
5133 * Do not check for channel private keys in message sending and
5134 reception if the channel does not have the PRIVKEY mode set.
5135 Affected file lib/silclient/client_channel.c.
5137 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5140 just surfaced after chaning the JOIN procedure.
5142 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added silc_client_get_clients_by_list to get client entries
5145 from Client ID list, that is returned for example by JOIN
5146 and USERS command replies. The application should use this
5147 function for example when JOIN command reply is received to
5148 resolve the clients already on the channel (library does not
5149 do that anymore as USERS command reply is not used in the JOIN
5150 procedure anymore). Affected files lib/silcclient/silcapi.h and
5151 lib/silcclient/idlist.c.
5153 * JOIN command reply and USERS command reply returns now SilcBuffer
5154 pointers instead of unsigned char pointers when returning
5155 the client list and mode list.
5157 * Added <Client ID> argument to the JOIN command reply, mainly
5158 for the server to identify for which client the command was
5159 originally sent. Updated protocol specs accordingly.
5161 * Added SilcDlist private_key pointer to the SilcChannelEntry
5162 in the client to support the channel private keys. Affected
5163 file is lib/silcclient/idlist.h.
5165 * Added SilcChannelPrivateKey argument to the function
5166 silc_client_send_channel_message so that application can choose
5167 to use specific private ke if it wants to. If it is not provided,
5168 the normal channel key is used, unless private keys are set.
5169 In this case the first (key that was added first) is used
5170 as the encryption key.
5172 * Implemented the support for channel private key handling.
5173 Implemented the following functions:
5175 silc_client_add_channel_private_key,
5176 silc_client_del_channel_private_keys,
5177 silc_client_del_channel_private_key,
5178 silc_client_list_channel_private_keys and
5179 silc_client_free_channel_private_keys
5181 Affected file lib/silcclient/client_channel.c.
5183 * Added the support for the private keys in the channel message
5184 sending and encryption and in the message reception and
5185 decryption. Affected funtions are
5186 silc_client_send_channel_message and silc_client_channel_message.
5188 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Added SKE's key verify callback to the client library's
5191 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5193 * Removed the statement that server (or router) must send USERS
5194 command reply when joining to the channel so that the client
5195 knows who are on the channel. Instead, the client list and
5196 client's mode list is now sent in the JOIN command reply to the
5197 client who joined channel. This is better solution.
5199 * Added function silc_server_get_users_on_channel and function
5200 silc_server_save_users_on_channel to the silcd/server.[ch].
5202 * Removed function silc_server_command_send_users from the
5205 * Do not show topic on the client library anymore. The topic is
5206 sent in the command reply notify to the application and the
5207 application must show the topic now.
5209 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Added client searching by nickname hash into the IDENTIFY and
5212 WHOIS commands in the server as they were clearly missing from
5213 them. Affected file is silcd/command.c.
5215 * Fixed a bug in private message receiving in the client library.
5216 The remote ID was freed and it wasn't supposed, now it is
5219 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Minor fix to the channel payload; allocate the data area, as it
5222 needs to be of specific length.
5224 * If the key agreement port is zero then the operating
5225 system will define the bound port. Affected files are
5226 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5228 * Added new function silc_channel_payload_decrypt into the file
5229 lib/silccore/silcchannel.[ch].
5231 * Moved the channel message etc, check from silc_packet_decrypt
5232 to applications. The library calls now a generic
5233 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5234 when the packet is either normal or special. This was done to
5235 allow more wide range of checking that was not allowed when
5236 the code was in library. Now applications can do virtually any
5237 checks to the packet and return to the library the decision how
5238 the packet should be processed. Affected files are
5239 lib/silccore/silcpacket.[ch].
5241 Added silc_server_packet_decrypt_check to the server and
5242 silc_client_packet_decrypt_check to the client library.
5244 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5245 to send with specified source and destination information.
5247 * Channel message delivery between routers was broken after the
5248 channel key distribution was fixed earlier. The channel key
5249 was used be to distributed to other routers as well which is not
5250 allowed by the protocol. Now this is fixed and channel keys
5251 really are cell specific and the channel message delivery between
5252 routers comply with the protocol specification.
5254 * Fixed various commands in server to check also the global list
5255 for the channel entry and not just the local list. The affected
5256 file silcd/command.c.
5258 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Added assert()s to buffer formatting and unformatting routines
5261 to assert (if --enable-debug) when error occurs. Affected
5262 file: lib/silcutil/silcbuffmt.c.
5264 * Changed to auto-reconnect to check whether the remote host is
5265 router and register the re-connect timeout if it is. It used
5266 to check that whether we are normal server, but router must do
5267 auto-reconnect with another router as well. Affected file
5270 * Removed the [<key len>] option from CMODE command as the cipher
5271 name decides the key length, nowadays. See the defined ciphers
5272 from the protocol specification.
5274 * Added [<hmac>] option to the CMODE command to define the HMAC
5275 for the channel. Added SILC_CMODE_HMAC channel mode.
5277 * Added [<hmac>] option for the JOIN command so that user can
5278 select which HMAC is used to compute the MACs of the channel
5281 * Added Hmac field to the Channel Message Payload. The integrity
5282 of plaintext channel messages are now protected by computing
5283 MAC of the message and attaching the MAC to the payload. The
5284 MAC is encrypted. Now, it is clear that this causes some
5285 overhead to the size of the packet but rationale for this is that
5286 now the receiver can verify whether the channel message decrypted
5287 correctly and also when private keys are set for the channel the
5288 receiver can decrypt the packet with several keys and check from
5289 the MAC which key decrypted the message correctly.
5291 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5292 lib/silccrypt/silccipher.[ch].
5294 * Added silc_hash_len to return the digest length into the
5295 lib/silcrypt/silchash.[ch].
5297 * Rewrote parts of Silc Channel Payload interface in the
5298 lib/silccore/silcchannel.[ch]. The encode function now also
5299 encrypts the packet and parse function decrypts it.
5301 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Fixed a minor formatting bug in the SKE's key material processing.
5304 It actually might have processed the keys wrong way resulting
5307 * Redefined the mandatory HMAC algorithms and added new algorithms.
5308 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5309 and hmac-md5 truncated to 96 bits. The mandatory is now
5310 hmac-sha1-96. Rest are optional (including the one that used
5311 to be mandatory). Rationale for this is that the truncated HMAC
5312 length is sufficient from security point of view and can actually
5313 make the attack against the HMAC harder. Also, the truncated
5314 HMAC causes less overhead to the packets. See the RFC2104 for
5317 * Added new [hmac] configuration section. The SKE used to use
5318 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5319 is of course wrong. The official names that must be proposed in
5320 the SKE are the ones defined in the protocol specification
5321 (hmac-sha1-96 for example). The user can configure any hmac
5322 using any hash function configured in the [hash] section. At
5323 least, the mandatory must be configured.
5325 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5327 * Added HMAC list to the SKE proposal list. It has now both
5328 hash algorithm list and HMAC list. This makes the protocol
5329 incompatible with previous versions. The SKE now seems to work
5330 the way it is supposed to work, for the first time actually.
5332 * Defined plain Hash algorithms to the protocol specification.
5335 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Implemented support for key agreement packets into the server.
5338 Added functions silc_server_key_agreement and
5339 silc_server_send_key_agreement. Other than these functions,
5340 server has nothing to do with this packet.
5342 * Added support for private message key packets into the server.
5343 Added functions silc_server_private_message_key and
5344 silc_server_send_private_message_key.
5348 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5349 called in the protocol's final callback instead in the END
5350 protocol state. This makes a little more sense and in the same
5351 time in client we can use the same protocol routines for normal
5352 key exchange and to key agreement packet handling as well.
5354 * Added to both client's and server's KE protocol context the
5355 SilcSKEKeyMaterial pointer to save the key material. We will
5356 bring the key material to the protocol's final callback by doing
5357 this. The final callback must free the key material.
5359 * Added SKE's packet_send callback into client's KE protocol
5360 context so that the caller can choose what packet sending function
5361 is used. This way we can use different packet sending when
5362 doing normal SKE when doing key agreement packet handling (in
5363 the key agreement packet handling we do not want to encrypt
5366 * Implemented the responder side of the key agreement routines
5367 in the client. The client can now bind to specified port and
5368 accept incoming key negotiation. The key material is passed
5369 to the application after the protocol is over.
5371 * Implemented the processing of incoming Key Agreement packet
5372 in the client. Added function silc_client_key_agreement to
5375 * Implemented the intiator side of the key agreement routines
5376 in the client. The client can now initiate key agreement with
5377 another remote client. The key material is passed to the
5378 application after the protocol is over.
5380 * Created client_keyagr.c to include all the key agreement
5383 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5384 SILC_TASK_CALLBACK except that it is not static.
5386 * Created client_notify.c and moved the Notify packet handling
5387 from the client.[ch] into that file.
5389 * Created client_prvmsg.c and moved all private message and
5390 private message key routines from the client.[ch] into that file.
5392 * Create client_channel.c and moved all channel message and
5393 channel private key routines from the client.[ch] into that file.
5395 * Changed silc_client_get_client_by_id_resolve to resolve with
5396 WHOIS command instead of IDENTIFY command, in the file
5397 lib/silclient/idlist.c.
5399 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Implemented the SKE's responder side to the Client library.
5403 * When FAILURE is received to the protocol do not trust it
5404 blindly. Register a timeout to wait whether the remote closes
5405 the connection as it should do it, only after that process the
5406 actual failure. This was changed to both client and server.
5408 * Added client_internal.h to include some of the structures
5409 there instead of client.h in lib/silcclient/.
5411 * Added function silc_task_unregister_by_callback to unregister
5412 timeouts by the callback function.
5414 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Some "Incomplete WHOIS info" errors has been appearing on the
5417 log files. Took away the entry->userinfo check from WHOIS
5418 reply sending. The entry->userinfo is now " " if client did not
5419 provide one. I thought this was fixed earlier but something
5420 is wrong still. Let's see if the error still appears.
5422 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Fixed a minor bug in the login when the channel key is
5425 re-generated in the server. It used to generate the key in
5426 wrong order and thus caused problems in the channel traffic.
5428 * Fixed a minor bug in channel key distsribution after
5429 KICK command. The key was not sent to the router even though
5432 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Added silc_ske_process_key_material_data as generic routine
5435 to process any key material as the SILC protocol dictates. The
5436 function is used by the actual SKE library but can be used by
5437 applications as well. This relates to the private message keys
5438 and the channel private keys since they must be processed the
5439 same way the normal SILC session keys. The protocol dictates
5440 this. Affected files: lib/silcske/silcske.[ch].
5442 Added also silc_ske_free_key_material to free the
5443 SilcSKEKeyMaterial structure.
5445 * Defined silc_cipher_set_key function to set the key for
5446 cipher without using the object's method function. The affected
5447 files: lib/silccrypt/silccipher.[ch].
5449 * Implemented silc silc_client_add_private_message_key,
5450 silc_client_add_private_message_key_ske,
5451 silc_client_del_private_message_key,
5452 silc_client_list_private_message_keys and
5453 silc_client_free_private_message_keys functions in the
5456 Added functions silc_client_send_private_message_key to send
5457 the Private Message Key payload and silc_client_private_message_key
5458 to handle incoming Private Message Key payload.
5460 * Added Cipher field to the Private Message Key payload to set
5461 the cipher to be used. If ignored, the default cipher defined
5462 in the SILC protocol (aes-256-cbc) is used.
5464 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Removed lib/silcclient/ops.h file.
5468 Redefined parts of the SILC Client Library API. Created new
5469 file silcapi.h that deprecates the ops.h file and defines the
5470 published Client Library API. Defined also private message key
5471 API and channel private key API into the file.
5473 This is the file that the application must include from the
5474 SILC Client Library. Other files need not be included by
5475 the application anymore.
5477 * Added new key_agreement client operation callback and also
5478 defined the Key Agreement library API for the application.
5480 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5483 is used by clients to request key negotiation between another
5484 client in the SILC network. If the negotiation is started it
5485 is performed using the SKE protocol. The result of the
5486 negotiation, the secret key material, can be used for example
5487 as private message key.
5489 Implemented the Key Agreement payload into the files
5490 lib/silccore/silauth.[ch].
5492 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Redefined ciphers for the SILC protocol. Added some new ciphers
5495 and defined the key lengths for the algorithms. Changed the
5496 code accordingly. The default key length is now 256 bits.
5498 * Fixed SKE key distribution function silc_ske_process_key_material
5499 when the key length is more than 128 bits. The default key
5500 length in SILC is now 256 bits.
5502 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5503 to indicate unsupported algorithm.
5505 * Renamed rijndael.c to aes.c and all functions as well.
5507 * Fixed a long standing channel key setting bug in client library.
5508 Weird that it has never surfaced before.
5510 * Fixed bug in channel deletion. If the entire channel is removed
5511 then it must also delete the references of the channel entry
5512 from the client's channel list as the client's channel entry and
5513 the channel's client entry share same memory.
5515 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Implemented CONNECT and SHUTDOWN commands in the client.
5519 * Implemented CLOSE command to the client.
5521 * Added the function silc_idlist_find_server_by_name into the
5522 files silcd/idlist.[ch].
5524 Added the function silc_idlist_find_server_by_conn into the
5525 files silcd/idlist.[ch].
5527 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * DIE command was renamed to SHUTDOWN. Updated the both code
5532 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5533 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5535 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5538 * Added function silc_server_create_connection function to create
5539 connection to remote router. My server implementation actually
5540 does not allow router to connect to normal server (it expects
5541 that normal server always initiates the connection to the router)
5542 so the CONNECT command is only good for connecting to another
5545 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5548 or some other client was kicked from the channel.
5550 Implemented the handling of the notify type to both client
5553 Implemented silc_server_send_notify_kicked to send the KICKED
5554 notify. It is used to send it to the server's primary router.
5556 * Implemented the KICK command into server and client.
5558 * Added `query' argument to the silc_idlist_get_client function
5559 to indicate whether to query the client from server or not if
5562 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5563 to indicate that the client is not channel founder.
5567 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Removed the rng context from SilcPacketContext structure and
5570 changed that the packet routine uses the Global RNG API.
5572 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Added support for quit message that client can "leave" on the
5575 channel when it quits the SILC. It is ditributed inside the
5576 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5578 Added silc_server_free_client_data that will take the
5579 signoff message as argument.
5581 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5583 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Updated parts of the protocol specification to keep it up
5588 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5591 payloads in one packet.
5593 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5594 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5595 use now the new List flag.
5597 * Also deprecated the following packet types: REPLACE_ID,
5598 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5600 * Added list support for Notify packet in server.
5602 * Added silc_server_send_notify_channel_change to send the
5603 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5604 the silc_server_send_replace_id.
5606 * Added silc_server_send_notify_nick_change to send the
5607 NICK_CHANGE notify type. Deprecates the function
5608 silc_server_send_replace_id.
5610 * Added silc_server_send_notify_join to send the JOIN notify type.
5611 Deprecates the function silc_server_send_new_channel_user.
5613 * Added silc_server_send_notify_leave to send LEAVE notify type.
5614 Deprecates the function silc_server_send_remove_channel_user.
5616 * Added silc_server_send_notify_cmode and
5617 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5618 types. Deprecates the silc_server_send_set_mode function.
5620 * Added SERVER_SIGNOFF notify type to indicate that server has
5621 quit. This means that all clients on the channel from that
5622 server will drop. This can be also used when netsplit happens.
5624 Deprecated REMOVE_ID packet type since it is not needed anymore
5627 Added silc_server_send_notify_server_signoff to send the
5628 SERVER_SIGNOFF notify type. Deprecates the function
5629 silc_server_send_remove_id.
5631 Added also silc_server_send_notify_signoff to send the
5632 SIGNOFF notify type.
5634 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5635 SILC protocol from this day on. Changed the protocol
5636 specification as well.
5638 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5639 notify type. It is used between routers to notify about
5640 topic changes on a channel.
5642 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5645 * Partly updated the protocol specification to comply with the
5646 changes now made. It is still though a bit outdated.
5648 * The JOIN notify type now takes one extra argument <Channel ID>.
5649 The packet used to be destined to the channel but now the
5650 JOIN type may be sent as list thus it is impossible to
5651 destine it to any specific channel. By adding this argument
5652 it is again possible.
5654 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Added CREDITS file. The CHANGES and CREDITS file will appear
5657 in the distribution as well.
5659 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5662 types in the server's silcd/packet_receive.c.
5664 * Implemented CMODE and CUMODE to work in router environment.
5666 * Fixed minor encoding and decoding buglet from the
5667 lib/silccore/silcmode.c.
5669 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5672 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5674 * Changed all SilcConfigServer* and silc_config_server* to
5675 SilcServerConfig* and silc_server_config*, respectively.
5678 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Associated the ID (client or server ID) to the Authentication
5681 Payload to avoid any possibility of forging. Updated the
5682 protocol specification and the code accordingly.
5684 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * The RSA key length is now save to the RsaKey context in the
5687 key generation process in lib/silccrypt/rsa.c. The key length
5688 is now used to figure out the maximum size of the block allowed
5689 to be encrypted/signed.
5691 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5692 is equivalent to the silc_mp_mp2bin but does not allocate any
5695 * Changed silc_mp_mp2bin API to take length argument. If it is
5696 non-zero then the buffer is allocated that large. If zero, then
5697 the size is approximated using silc_mp_sizeinbase, which however
5700 * Created Global RNG API which is global RNG that application can
5701 initialize. After initializing, any routine anywhere in the
5702 code (including library) can use RNG without allocating a new
5703 RNG object. This was done to allow this sort of use of the
5704 RNG in code that has no chance to allocate RNG object. All
5705 applications currently allocate this and many routines in the
5706 library use this. Affected file lib/silccrypt/silcrng.[ch].
5708 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5709 it to use the Global RNG API.
5711 * Defined Authentication Payload into protocol specification that
5712 is used during SILC session to authenticate entities. It is
5713 used for example by client to authenticate itself to the server
5714 to obtain server operator privileges.
5716 Implemented this payload into the lib/silccore/silcauth.[ch].
5717 Implemented also routines for public key based authentication
5718 as the new protocol specification dictates.
5720 Moved definitions of different authentication methods from
5721 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5723 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5724 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5725 silc_pkcs_verify_with_hash functions into the file
5726 lib/silccrypt/silcpkcs.[ch].
5728 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * The client entry's userinfo pointer must be always valid.
5731 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5732 will fail since it requires the userinfo. Now, the userinfo
5733 is allocated as "" if actual userinfo does not exist. Actually,
5734 it must exist and it is totally Ok to drop client connections
5735 that does not announce the userinfo. However, we will make
5736 this workaround for now.
5738 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5739 to return the remote port by socket.
5741 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5744 SILC_SERVER_PENDING_EXEC and added an new macro
5745 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5746 data or when error occurs while processing the pending command.
5748 Added new argument `destructor' into silc_server_command_pending
5749 and to the SilcServerCommandPending object. This destructor is
5750 now called after calling the pending callback or if error occurs
5751 immediately. If error occurs the actual pending callback won't
5752 be called at all - only the destructor. The destructor may be
5753 NULL if destructor is not needed.
5755 All this applies for client library code as well. Similar
5756 changes were made there as well for the pending commands.
5758 In the client, the application must now allocate the
5759 SilcClientCommandContext with the silc_client_command_alloc
5762 * Added reference counter to the SilcServerCommandContext. Added
5763 function silc_server_command_alloc and silc_server_command_dup
5766 Same type of functions added to the client library for the same
5769 * Removed the cmd_ident from IDListData away since it is now
5770 global for all connections. It is the command identifier used
5771 in command sending and with pending commands. The affected file
5774 * Added reference counter to the SilcSocketConnection objecet to
5775 indicate the usage count of the object. The object won't be
5776 freed untill the reference counter hits zero. Currently only
5777 server uses this, and client ignores it. The client must be
5778 set to use this too later. The affected files are
5779 lib/silccore/silcsockconn.[ch]. Added also the function
5780 silc_socket_dup to increase the reference counter.
5782 This was mainly added because it is possible that the socket
5783 is removed underneath of pending command or other async
5784 operation. Now it won't be free'd and proper DISCONNECTING
5785 flags, etc. can be set to avoid sending data to connection that
5786 is not valid anymore.
5788 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5789 the connection. After that it sets SILC_SET_DISCONNECTED.
5790 It is, however, possible that the socket data is not still freed.
5791 The silc_server_packet_process now checks that data is not
5792 read or written to connection that is DISCONNECTED. The socket
5793 get's freed when the reference counter hits zero.
5795 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Changed the client operation API: channel_message operation's
5798 `sender' is now the client entry of the sender, not the nickname
5799 and the `channel' is the channel entry, not the channel name.
5801 In the private_message operation the `sender' is now also the
5802 client entry of the sender not the nickname.
5804 Affected file is lib/silcclient/ops.h and all applications
5805 using the client operations.
5807 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Moved the calling of ops->connect() from connect_to_server_final
5810 into receive_new_id functin since that is the point when the
5811 client is actually allowed to send traffic to network. The
5812 affected file is lib/silcclient/client.c.
5814 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5817 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5818 (if needs broadcasting) instead of broadcasting the packets one
5819 by one which would make a burst in the network traffic.
5821 * Added `broadcast' argument to the functions in silcd/server.[ch]
5822 silc_server_create_new_channel[_with_id] to indicate whether
5823 to send New Channel packet to primary router.
5825 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Added new function into the silcd/server.[ch] files:
5828 silc_server_create_new_channel_with_id to create new channel with
5829 already existing Channel ID.
5831 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5832 lib/silccore/silcpacket.h. This packet is used t send list of
5833 Set Mode payloads inside one packet. Server uses this to set
5834 the modes for the channels and clients on those channels, that it
5835 announced to the router when it connected to it. The protocol
5836 specification has been updated accordingly.
5838 * The silc_server_new_channel did not handle the packet coming
5839 from normal server as it normally does not send that. However,
5840 when it announces its channels it does send it. Implemented
5841 the support for that.
5843 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5844 into the file lib/silccore/id.h.
5846 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Fixed memory leaks in the functions silc_idlist_del_client,
5849 silc_idlist_del_channel and silc_idlist_del_server in the file
5850 silcd/idlist.c. All of those leaked like a sieve.
5852 * Fixed some small memory leaks in the client's function
5853 silc_client_notify_by_server.
5855 * Added functions into silcd/server.c: silc_server_announce_clients,
5856 silc_server_announce_channels and silc_server_announce_server.
5857 These functions are used by normal and router server to announce
5858 to its primary router about clients, channels and servers (when
5859 router) that we own. This is done after we've connected to the
5862 These functions effectively implements the following packet types:
5863 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5864 and SILC_PACKET_NEW_ID_LIST.
5866 * Added new functions into the silcd/packet_receive.[ch]:
5867 silc_server_new_id_list, silc_server_new_channel_list and
5868 silc_server_new_channel_user_list to handle the incoming
5869 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5871 * Added support of changing Channel ID in the function
5872 silc_server_replace_id. If the server that announces a channel
5873 to the router already exists in the router (with same name but
5874 with different Channel ID), router is responsible to send
5875 Replace ID packet to the server and force the server to change
5876 the Channel ID to the one router has.
5878 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5879 client that the Channel ID has been changed by the router. The
5880 normal server sends this to the client. Client must start using
5881 the new Channel ID as the channel's ID.
5883 Implemented handling of this new type into lib/silcclient/client.c
5884 into the function silc_client_notify_by_server.
5886 * Added new function silc_idlist_replace_channel_id into the files
5887 silcd/idlist.[ch] to replace the Channel ID.
5889 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Call silc_server_command_identify_check always when processing
5892 the IDENTIFY command in silcd/command.c
5894 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5897 send keepalive packets. The packet can be sent by clients,
5898 servers and routers.
5900 Added function silc_socket_set_heartbeat into the file
5901 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5902 If not set, the heartbeat is not performed. The actual
5903 heartbeat is implemented in the low level socket connection
5904 library. However, application is responsible of actually
5907 Added silc_server_send_heartbeat to send the actual heartbeat
5908 packet into silcd/packet_send.[ch]. Server now performs
5909 keepalive with all connections.
5911 * Added silc_task_get_first function into lib/silcutil/silctask.c
5912 to return the timeout task with shortest timeout. There was a bug
5913 in task unregistration that caused problems. TODO has been
5914 updated to include that task system must be rewritten.
5916 * The client library will now resolve the client information when
5917 receiving JOIN notify from server for client that we know but
5918 have incomplete information.
5920 * Rewrote parts of silc_server_remove_from_channels and
5921 silc_server_remove_from_one_channel as they did not remove the
5922 channel in some circumstances even though they should've.
5924 * Encryption problem encountered in server:
5926 The LEAVE command used to send the Channel Key packet to the
5927 router immediately after generating it. However, the code
5928 had earlier sent Remove Channel user packet but not immediately,
5929 ie. it was put to queue. The order of packets in the router
5930 was that Channel Key packet was first and Remove Channel User
5931 packet was second, even though they were encrypted in the
5932 reverse order. For this reason, MAC check failed. Now, this
5933 is fixed by not sending the Channel Key packet immediately but
5934 putting it to queue. However, this is more fundamental problem:
5935 packets that are in queue should actually not be encrypted
5936 because packets that are sent immediately gets encrypted
5937 actually with wrong IV (and thus MAC check fails). So, packets
5938 that are in queue should be encrypted when they are sent to
5939 the wire and not when they put to the queue.
5941 However, the problem is that the current system has not been
5942 designed to work that way. Instead, the packet is encrypted
5943 as soon as possible and left to the queue. The queue is then
5944 just purged into wire. There won't be any fixes for this
5945 any time soon. So, the current semantic for packet sending
5948 o If you send packet to remote host and do not force the send
5949 (the packet will be in queue) then all subsequent packets to the
5950 same remote host must also be put to the queue. Only after the
5951 queue has been purged is it safe again to force the packet
5954 o If you send all packets immediately then it safe to send
5955 any of subsequent packets through the queue, however, after
5956 the first packet is put to queue then any subsequent packets
5957 must also be put to the queue.
5959 Follow these rules and everything works fine.
5961 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Added new function silc_server_remove_clients_by_server to
5964 remove all client entries from ID list when the server connection
5965 is lost. In this case it is also important to invalidate all
5966 client entires as they hold the invalid server entry. This
5967 fixes fatal bug when server has lost connection and will reconnect
5970 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Made some sanity checks to silc_server_daemonise like to check
5973 whether the requested user and group actually exists.
5975 * Added sanity check to SKE's silc_ske_responder_finish to check
5976 that the public and private key actually is valid.
5978 * Invalidate the client's nickname when receiving Replace ID
5979 packet and the Client ID is being replaced. This means that the
5980 server will query the nickname if someone needs it (client)
5983 * Sort the ID Cache in client library when the ID Cache data
5984 has changed (needs sorting).
5986 * Do not allow for SILC client to create several connections to
5987 several servers. The client does not support windows right now
5988 and generating multiple connections causes weird behaviour.
5990 Irssi-silc client does support windows and can handle several
5991 connections without problems, see: www.irssi.org and SILC plugin.
5993 * Fixed some places where client was added to the IDList. The
5994 rule of thumb is following (in order to get everything right):
5995 If the client is directly connected local client then the
5996 `connection' argument must be set and `router' argument must be
5997 NULL to silc_idlist_add_client function. If the client is not
5998 directly connected client then the `router' argument must
5999 bet set and the `connection' argument must be NULL to the
6000 silc_idlist_add_client function.
6002 * The funtion silc_server_packet_send_local_channel actually did
6003 not check whether the client was locally connected or not. It
6004 does that now. Fixed a bug related to LEAVE command.
6006 * Fixed Remove Channel User payload parsing bug in server's
6007 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6009 * The server's silc_server_save_channel_key now checks also the
6010 global ID list for the channel as it might not be in the local
6011 list. Fixed a bug related to LEAVE command.
6013 * Is this the end of the [<unknown>] buglet that has been lurking
6014 around for a long time? A little for loop fix in server's
6015 silc_server_command_whois_parse that is used by both IDENTIFY
6016 and WHOIS command. At least, this was a clear bug and a cause
6017 of one type of [<unknown>] buglet.
6019 * WHOIS and IDENTIFY commands call the function
6020 silc_server_command_[whois/identify]_check function even if
6021 we are not router server.
6023 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Added --with-gmp configuration option. If set the GMP
6026 is always compiled in the SILC source tree. If not set then
6027 it is checked whether the system has the GMP3 installed. If
6028 it has then the GMP won't be compiled (the system's headers
6029 and library is used), if it doesn't have it then the GMP is
6030 compiled in the SILC source tree.
6032 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Changed RSA private exponent generation to what PKCS #1
6035 suggests. We try to find the smallest possible d by doing
6036 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6037 not security fix but optimization.
6039 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Added new config entry [Identity] to fork the server and run
6042 it as specific user and group. A patch from Bostik.
6044 * Imported Dotconf configuration library into lib/dotconf.
6045 This will be used to create the SILC configuration files later.
6046 It will appear in the distsribution after this commit.
6048 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * A big code auditing weekend happening. Auditing code for
6051 obvious mistakes, bugs and errors. Also, removing any code
6054 Removed files for being obsolete:
6056 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6057 inline in the file lib/silcutil/silcbuffer.h)
6059 o lib/silcutil/silcbufutil.c (the header has inline versions)
6061 Changed code to fix possible error conditions:
6063 o The buffer formatting routines now check that the destination
6064 buffer really has enough space to add the data. This applies for
6065 both buffer formatting and unformatting
6066 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6067 unformatting was changed to accomodate following rules:
6068 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6069 sent to the function while XXX_*STRING will not allocate or copy
6070 the data into the buffer. Instead it sets the pointer from the
6071 buffer into the pointer sent as argument (XXX_*STRING used to
6072 require that the pointer must be allocated already). This change
6073 makes this whole thing a bit more consistent and more optimized
6074 (note that the data returned in the unformatting with XXX_*STRING
6075 must not be freed now). The routines return now -1 on error.
6077 o Tried to find all code that use buffer_format and buffer_unformat
6078 and added return value checking to prevent formatting and
6079 especially unformatting errors and possible subsequent fatal
6082 o Changed ske->x and ske->KEY to mallocated pointers in
6083 lib/silcske/silcske.h. Fixed possible data and memory leak.
6085 o Added return value checking to all *_parse* functions. Fixed
6086 many memory leaks as well.
6088 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6089 so that buffer overflows would not happen. All code now also
6090 checks the return value as it can fail.
6092 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Added reconnection support to server if the normal server looses
6095 its connection to the router (for example if router is rebooted).
6096 The server performs normal reconnection strategy implemented
6097 to the server. Affected file silcd/server.c.
6099 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added new packet type SILC_PACKET_SET_MODE that is used to
6102 distribute the information about changed modes (for clients,
6103 channels and clients channel modes) to all routers in the
6104 network. Updated the protocol specification accordingly.
6106 Added functions into silcd/packet_send.c and
6107 silcd/packet_receive.c: silc_server_send_set_mode,
6108 silc_server_set_mode.
6110 Added new files silcmode.[ch] into lib/silccore that implements
6111 the encoding and decoding of Set Mode Payload. Added new type
6112 SilcSetModePayload. Moved the definitions of different modes
6113 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6115 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Oops, a little mistake in server's connection authentication
6118 protocol. The protocol is not ended with FAILURE but with
6119 SUCCESS if the authentication is Ok. :) Affected file is
6122 * Implemented NICK_CHANGE notify handling in server in the file
6123 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6124 the local clients on the channel. After the changing nickname
6125 in router environment snhould work and the [<unknown>] nickname
6126 should appear no more.
6128 The silc_server_replace_id function that receives the Replace ID
6129 payload now sends the NICK_CHANGE notify type also in the file
6130 silcd/packet_receive.c
6132 * Changed WHOIS and IDENTIFY command to support the maximum amount
6133 of arguments defined in protocol specs (3328 arguments). This
6134 fixed a bug that caused problems when there were more than three
6137 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Added extra parameter, command identifier, to the
6140 silc_client_send_command so that explicit command identifier
6143 Changed that ID list routines uses specific command identifier
6144 when sending WHOIS/IDENTIFY requests to the server so that they
6145 can be identified when the reply comes back.
6147 Affected files lib/silcclient/command.[ch],
6148 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6150 * Added `sender' argument to silc_server_packet_send_to_channel
6151 to indicaet the sender who originally sent the packet to us
6152 that we are now re-sending. Ignored if NULL. Affected file
6153 silcd/packet_send.[ch].
6155 * Added some server statistics support in silcd/server_internal.h
6156 SilcServerStatistics structure and around the server code. Also
6157 send some nice statistics information when client is connecting
6160 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Fixed channel ID decoding in server's JOIN command reply in
6163 silcd/command_reply.c
6165 * Fixed braodcasting of replace ID payload to not to send it if
6166 we are standalone server in silcd/packet_receive.c.
6168 * Fixed all channel message sending routines to not to send
6169 packets to clients that has router set, since they are routed
6170 separately in the same function earlier. Affects file
6171 silcd/packet_send.c and all channel packet sending functions.
6173 * In USERS reply, res_argv[i] are not allocated, the table
6174 is allocated. Thus changed that free the table, not its
6177 * In server's whois_check and identify_check if the client is
6178 locally connected do not send any WHOIS commands - they are not
6181 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Fixed some minor bugs in client when sending WHOIS command. The
6184 arguments was in wrong order.
6186 * Removed statis function add_to_channel from server in
6187 silcd/command.c that was previously used with the joining but
6190 * Tested USERS command in router environment successfully with two
6191 routers, two servers and two clients.
6193 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Reorganized the USERS command and command reply in client library
6196 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6197 When the command is given by user we register a pending command
6198 callback that will reprocess the command after the reply has been
6199 received from the server. When reprocessing the packet we then
6200 display the information. Thus, the USERS information is displayed
6201 now in the command callback instead of in the command reply
6202 callback. The processing of the command is same as previously
6203 when server has sent the command reply in the JOINing process.
6205 * Added to USERS command in silcd/command_reply.c to join the client,
6206 we didn't use to know about, to the channel after we've created
6207 a client entry for it. Also, for clienet we did know already still
6208 check whether it is on the channel or not and add it if not.
6210 * Removed silc_server_command_join_notify as the function and its
6213 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Changed the client's pending command handling to the same as the
6216 server's pending command handling. It is also now possible to
6217 execute command reply functions from other command reply
6218 function as the function callbacks for commands and command
6219 replies are one and same. The pending commands are not static
6220 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6221 in client connection context. Thus, pending commands are server
6222 connection specific as it is convenient.
6224 Changed the function silc_client_command_pending and
6225 silc_client_command_pending_del and added new function
6226 silc_client_command_pending_check. Removed the
6227 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6230 * Added cmd_ident, current command identifier, to the client
6231 connection context in lib/silcclient/client.h to keep track on
6232 command identifiers used in command sending. Client's command reply
6233 function handling now supports the mandatory command identifiers.
6235 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6236 funtions in client to fully support pending command callbacks.
6238 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6239 as one of the arguments to the application in the command reply
6242 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6243 before first releasing SILC but came back. Now it is removed again
6244 and should come back nomore. The FORWARDED flag was used only
6245 by the JOINing procedure by forwarding the command packet to router.
6246 Now, the JOINing procedure has been changed to more generic (due
6247 to various router environment issues) and FORWARDED is not needed
6248 anymore for anything. The protocol specification is yet to be
6251 Now, removed silc_server_packet_forward from server and the flag
6252 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6254 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Renamed NAMES command to USERS command. The NAMES was named that
6257 due to historical reasons. Now it is renamed. Also, rewrote
6258 parts of the USERS command. The nickname list is not sent anymore
6259 by the server. Only Client ID and mode lists are sent in the USERS
6260 command. Changed this also to the protocol specification.
6262 The client now resolves the names and stuff after it receives
6263 the USERS list from the server when joining to the channel.
6265 * WHOIS and IDENTIFY commands has been changed to support multiple
6266 Client ID's per command. One can now search for multiple users
6267 in the network by sending only one WHOIS or IDENTIFY command.
6268 Changed the code and the protocol specifications.
6270 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6271 uses silc_server_command_whois_parse to parse the request. */
6273 * If normal server, do not parse the WHOIS and IDENTIFY requests
6274 before sending it to the router. Saves some time.
6276 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6278 * Fixed JOIN command on client library. Wrong number of arguments
6279 used to crash the client.
6281 * Added silc_server_channel_has_global function to check whether
6282 channel has global users or not.
6284 * Added silc_server_channel_has_local function to check whether channel
6285 has locally connected clients on the channel.
6287 * The silc_server_remove_from_one_channel now checks whether the
6288 channel has global users or not after given client was removed from
6289 the channel. It also checks whether the channel has local clients
6290 on the channel anymore. If it does not have then the channel entry
6291 is removed as it is not needed anymore.
6293 * The silc_server_notify now checks on JOIN notify whether the joining
6294 client is one of locally connected or global. If it is global then
6295 the channel has now global users on the channel and that is marked
6296 to the channel entry. Also, it now saves the global client to
6297 global list who is joining and JOINs it to the channel. This is
6298 for normal server, that is.
6300 Changed silc_server_send_notify_on_channel,
6301 silc_server_packet_relay_to_channel and
6302 silc_server_packet_send_to_channel check if we are normal server
6303 and client has router set (ie. global client) do not send the
6304 message to that client, as it is already routed to our router.
6306 * Implemented LEAVE notify type handling in silc_server_notify
6309 * Tested LEAVE command in router environment successfully. Tested
6310 with two routers, two servers and two clients.
6314 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6316 * Implemented SIGNOFF notify type handling in silc_server_notify
6319 * silc_server_remove_id now removes the client entry from all channels
6320 it has joined and thusly sends SIGNOFF notify type.
6322 * Rewrote the NAMES list generation in server by removing two excess
6323 loops. The lists are created now inside one loop.
6325 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * silc_server_remove_channel_user checks now also global list
6328 for channel and client.
6330 * silc_server_new_channel_user checks now both local and global
6331 list for channel and client. Fixed a bug in client id decoding.
6332 Used to decode wrong buffer.
6334 * silc_server_channel_message checks now both local and global
6335 list for channel entry.
6337 * Tested channel joining (hence JOIN) in router environment
6338 successfully. Tested with two routers, two servers and two
6341 * Tested channel message sending in router environment successfully.
6343 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Added silc_server_save_channel_key into server.[ch] to save the
6346 received channel key in Channel Key payload processing. It is
6347 also used in JOIN command reply handling.
6349 Equivalent function silc_client_save_channel_key added into
6350 client.[ch] into client library.
6352 * Changed JOIN command reply to send information whether the channel
6353 was created or not (is existing already) and the channel key
6354 payload. Changed protocol specs accordingly.
6356 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6357 the request was sent by ID and not by nickname. Crashed on
6360 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6363 now correctly save the received data.
6365 * silc_server_free_sock_user_data now notifies routers in the
6366 network about entities leaving the network.
6368 At the same time implemented functions silc_server_remove_id
6369 and silc_server_send_remove_id to receive and send REMOVE_ID
6370 packets. The packet is used to notify routers in the network
6371 about leaving entities. The ID removed will become invalid in
6374 * Added function silc_idlist_del_server into server. Removes and
6375 free's server entry from ID list.
6377 * silc_server_private_message function now checks, if we are router,
6378 that the destination ID really is valid ID, naturally.
6380 * In router when NEW_ID packet is received (for new client) the
6381 hash of the Client ID is saved in the ID Cache but the
6382 client->nickname is set to NULL, instead of putting the hash
6385 IDENTIFY command now also checks that client->nickname must be
6386 valid. If it is not if will request the data from the server who
6387 owns the client. Added new function
6388 silc_server_command_identify_check.
6390 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6391 to set the command to already allocated Command Payload.
6393 * Tested private message sending in router environment with two
6394 routers, two servers and two clients. Fixed minor bugs and now
6397 * Fixed segfault from client's NAMES command. Used to crash if
6400 * Forwarded packets must not be routed even if it is not destined
6401 to the receiver. Changed server code comply with this.
6403 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Added `require_reverse_mapping' boolean value to ServerParams
6406 structure. If TRUE (not default) the server will require that
6407 the connecting host has fully qualified domain name.
6409 If the reverse mapping is not required and hostname could not be
6410 found the IP address is used as hostname.
6412 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Implemented version string checking to both client and server.
6415 The check is incomplete currently due to the abnormal version
6416 strings used in development version of SILC.
6418 * Changed all command functions in server to use the new
6421 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Changed char *data to unsigned char *data in ID Cache system to
6424 support binary data as ID Cache data. Changed code to support
6425 binary data in lib/silccore/idcache.c.
6427 * Renamed silc_server_packet_relay_command_reply to
6428 silc_server_command_reply as it is normal packet receiving
6429 function. Rewrote the function to accept command replys for
6430 servers and not only for clients.
6432 * Mark remote router always as registered server if we are connecting
6433 to it. Otherwise, commands sent by the router to us are ignored.
6435 * All ID List find routines now returns the ID Cache Entry pointer
6436 as well if requested.
6438 * WHOIS command works now in router environment, tested with two
6439 routers, two servers and two clients.
6441 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6442 in router environment (as it is almost equivalent to WHOIS) but
6443 hasn't been tested thoroughly. Added new functions:
6445 silc_server_command_identify_parse
6446 silc_server_command_identify_send_reply
6447 silc_server_command_identify_from_client
6448 silc_server_command_identify_from_server
6450 * Disabled route cache adding because adding two different ID's with
6451 same IP replaces the old cache entry thus giving wrong route.
6452 The entry->router->connection is always the fastest route anyway
6453 so route cache may not be needed. Of course, new routes maybe
6454 established after receiving the ID when the entry->router->connection
6455 might not be anymore the most optimal.
6457 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Add route cache for received ID for fast routing.
6461 * Added silc_server_packet_route to route received packet on router
6462 that is not destined to us.
6464 * Renamed silc_server_get_route to silc_server_route_get.
6466 * Added id_string and id_string_len fields into SilcServer to
6467 include encoded ServerID for fast comparing without excess
6468 encoding of the ID's.
6470 * Cleaned up WHOIS command on server side. Added following static
6473 silc_server_command_whois_parse
6474 silc_server_command_whois_check
6475 silc_server_command_whois_send_reply
6476 silc_server_command_whois_from_client
6477 silc_server_command_whois_from_server
6479 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6480 arguments in command replies. All command functions should be
6481 updated to use this macro.
6483 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Minor typo fixes on command reply handling on server.
6487 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Added silc_server_command_add_to_channel internal routine to add
6490 the client to the channel after router has created the channel and
6491 sent command reply to the server.
6493 * Added generic silc_server_send_command to send any command from
6496 * Use static buffer with ID rendering instead of duplicating data.
6498 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Fixed a channel user mode bug when joining to a channel server gave
6501 everybody channel founder rights, oops.
6503 * We mark ourselves as the router of the incoming server connection
6504 if we are router ourselves. This way we can check in some packet
6505 sending functions whether it is locally connected server. For
6506 incoming router connections we put NULL.
6508 * For router sending packets locally means now always sending the
6509 packet cell wide; to local clients and local servers. For normal
6510 server sending packet locally means sending it to only local
6513 * Fixed the JOIN command to really work in router environment. If the
6514 channel is created it is always created by the router. Router is
6515 also responsible of making the initial joining to the channel,
6516 sending JOIN notify to the sending server and distributing
6517 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6518 does not exist server doesn't do anything else but forward the
6519 command to the router which performs everything.
6521 * Added silc_server_send_channel_key function to send the Channel Key
6524 * Added silc_server_create_channel_key to create new channel key. The
6525 channel key is now re-generated everytime someone joins or leaves
6526 a channel, as protocol dictates. Note: channel->key_len is the
6529 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6532 packet_receive.[ch] to separate packet sending and receiving
6533 routines. The server.[ch] now includes everything else including
6534 actual packet processing (writing and reading data) and other
6537 Renamed silc_server_private_message_send_internal to
6538 silc_server_send_private_message. The routine is still though
6539 used only to relay private messages as server does not send
6540 private messages itself.
6542 Renamed silc_server_new_channel to silc_server_create_new_channel
6543 and added new function sicl_server_new_channel that handles the
6544 incoming New Channel packet. Added also new sending function
6545 silc_server_send_new_channel to send New Channel Payload.
6547 * Added new function silc_server_notify to process incoming notify
6548 packet to the server/router. Server may then relay the notify
6549 to clients if needed.
6551 * Added new function silc_server_new_channel_user to process incoming
6552 New Channel User packet. Router will redistribute the packet and
6553 send JOIN notify to its local clients and locally connected servers
6554 if needed. Normal server will send JOIN notify to its local client
6555 on same channel when received this packet. Added also corresponding
6556 sending function silc_server_send_new_channel_user to sent the
6559 * Added boolean route argument to send_notif_to_channel and
6560 packet_send_to_channel functions to attempt to route the packet
6561 if it is TRUE and send only locally if it is FALSE.
6563 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6565 * silc_server_replace_id now broadcasts the received replace ID
6566 packet if it is not broadcast packet already. The router must
6567 broadcast to inform other routers about changed ID.
6569 * Added backpointer to server's router into SilcServer context in
6570 silcd/server_internal.h.
6572 * Fixed silc_server_packet_broadcast to send correct broadcast
6575 * The channel key is now distributed to the local client as soon
6576 as it is received from the router (in router environment) so that
6577 no other packet may be sent for the channel until client has
6580 * silc_server_remove_channel_user now broadcasts the received
6581 Remove Channel User packet if it is not broadcast packet already.
6582 The router must broadcast to inform other routers about removed
6585 * Added users field into SilcPacketContext that is a reference count
6586 of the context. One can increase the reference count by calling
6587 silc_packet_context_dup which is now changed to just increase the
6588 reference count instead of duplicating the data. The reference
6589 count is decresed by calling silc_packet_context_free that will
6590 free the data after the reference count hits zero.
6592 For now on the packet context and everything allocated into it
6593 (including the raw packet from network) must be freed by calling
6594 the new silc_packet_context_free function. Added also new function
6595 silc_packet_context_alloc that must be used now to allocate the
6596 context. This also means that if a routine is asynchronous from
6597 silc_[client/server]_packet_parse_type the packet context must
6598 be duplicated by calling silc_packet_context_dup. Otherwise it
6599 gets free'd after silc_[client/server]_packet_parse_type returns.
6600 Also, one must remember that if packet is duplicated then its
6601 reference count must be decresed by calling the free function as
6602 many times as it was duplicated.
6604 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6605 from both client and server.
6607 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Made joining to a channel working in router environment.
6611 * Cleaned up JOIN command on server side and create function
6612 silc_server_command_join_channel internal routine to make the
6615 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Changed silc_command_pending list to SilcDList. Also, added
6618 `ident' field to SilcServerCommandPending structure to identify
6619 the reply and to call correct callback.
6621 Added silc_server_command_pending_check function to replace the
6622 corresnponding macro. The silc_command_pending list is not
6625 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6626 to set identifier to previously allocated Command Payload. It
6627 is used to set identifier for command when resending Command
6630 * Added silc_command_payload_encode_payload to encode Command
6631 Payload buffer from SilcCommandPayload structure.
6633 * Added silc_argument_payload_encode_payload to encode Argument
6634 payload buffer from SilcArgumentPayload structure.
6636 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Changed WHOIS command to support router connection on server side.
6639 The whois request is always sent to router unless the server is
6640 standalone server. After server has received the reply from the
6641 router will it send the reply to the client.
6643 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6644 broadcast received broadcast packet. The function is used only
6645 by router. The broadcast packet is always sent to the router's
6648 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6649 render given ID to printable string, for log files for example.
6651 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Made basic router to router connections working. At least they
6654 can now connect to each other but nothing really works the way
6655 they are supposed - yet.
6657 * Added new initiator token to RouterConnection configuration
6658 file in silcd/serverconfig.[ch]. It is used to tell whether we
6659 are the initiator to the remote router or whether we'll expect
6660 the other end to connect.
6662 * Moved registering of listener task to silc_server_init, hence
6663 the server starts listenning as soon as it is run, even if it
6664 does not have connections to other routers. Let's see how well
6667 * Changed default connection retry timeouts for more suitable in
6670 * Removed cipher and such arguments from silc_idlist_add_client
6671 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6672 Added new function silc_idlist_add_data to add the keys and stuff
6675 * Added SilcIDListData structure and added it to SilcClientEntry
6676 and SilcServerEntry as their first field in the structure. This
6677 way we can explicitly cast the ID entries to the SilcIDListData
6678 structure and get common data for the entries. In past, we had
6679 to first check what type of connection it is and then cast it to
6680 correct ID entry type. Now, we can directly cast the opaque
6681 pointer to the SilcIDListData (no matter what ID entry it actually
6682 is) and get the data needed.
6684 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6687 in some circumstances even if threre were timeout tasks, though not
6688 IO tasks, but tasks anyway. Now fixed.
6690 * Defined SilcServerConnection structure to hold connection specific
6691 stuff about directly connected servers and routers. The definition
6692 is currently in silcd/server_internal.h. I thought about having
6693 a bit more important role fro this struct but for now it is used
6694 only when connecting to other server (or router actually).
6696 * Added connecting retry support in server when connecting to
6697 router(s). The retry feature implement exponential backoff
6698 algorithm. Also, added SilcServerParams structure to hold default
6699 parameters for server. For now, it include these retry settings
6700 and are hard coded. After server is moded to be as Silc Server
6701 Library this structure will be more important.
6703 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Changed client librarys channel->clients table to SilcList and
6706 changed code accordingly.
6708 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6710 * Changed client's channel table to SilcList and changed code
6711 accordingly. Also changed SilcChannelClientEntry to include back-
6712 pointer to the channel so that client entry can use that structure
6713 as list as well and we have fast cross-reference to the channel.
6714 This change dramatically decreased the complexity of channel
6715 handling with client entry and vice versa (removed one extra
6716 loop when searching for channel entry from many functions).
6718 * Changed server->sim from table to SilcDList and changed code
6721 * NAMES command can now be used from user interface. It will show
6722 the user list on the channel, neatly.
6724 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6725 Code now saves realname of the user if it becomes available.
6727 * Renamed configure.in to configure.in.pre and made ./prepare
6728 script to automatically add correct version string to
6729 configure.in which it creates from configure.in.pre.
6731 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6733 * NAMES command reply now shows users mode with the nickname when
6736 * Moved silc_client_ch[u]mode[_char] functions from
6737 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6738 place sucks, they are utility functions and should be in some
6741 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6743 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6746 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added TRQ (efficient deque and list library) into lib/trq. This is
6751 a very good list library that is currently used in the SILC. Defined
6752 SilcList API over the library because I didn't like the API very
6753 much. See lib/trq/silclist.h for the API and examples of how to
6754 use the API. Fixed various places in the code to use the new
6755 SilcList API. The SilcList is meant for lists that has a structure
6756 already defined as a list. It is not suitable to add just some
6757 context to the list (in TRQ, the context is the list actually).
6759 So, I defined SilcDList that can be used for the purpose where
6760 predefined list structure does not exit. This can be used as
6761 such list. Now some context just can be added to the SilcDList.
6762 Currently this list is not used in the SILC just yet, though there
6763 are a lot places where this can replace dynamically allocated
6764 tables and I will fix these places, later, to use SilcDList.
6765 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6766 and use TRQ internally).
6768 Also fixed some annoying warning messages that the original TRQ
6769 code generated. Also minor changes to TRQ's Makefile.in.
6771 * Added support for querying by Client ID to both WHOIS and
6772 IDENTIFY commands into server, as required by the protocol.
6774 * Removed method function pointers from SilcBuffer structure. They
6775 weren't used to anything and just increased the context size for
6776 no good reason. This change also made silc_buffer_alloc and
6777 silc_buffer_free functions inline functions.
6779 * Disabled command flooding detection support until it's fixed so
6780 that it accepts commands in but does not execute them more than once
6783 * Added silc_net_localhost(), to return local hostname, into
6784 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6785 that must be initialized before calling silc_client_init.
6787 * Added new function: silc_server_send_notify_on_channels to send
6788 notify messages to all channels client has joined. It is assured
6789 that the message is sent only once per client.
6791 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6792 lib/silcutil/silcutil.[ch] as silc_format function. The new
6793 function is generic and is used by server as well, not only by
6794 the logging routines.
6796 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6797 the provided version string was not acceptable. Added new function:
6798 silc_ske_check_version into lib/silcske/silcske.h. The function
6799 must be implemented by the application (client or server) and it
6800 does not reside in the SKE library. The function checks the version
6801 string remote end sent.
6803 * Added back pointers (to opaque context and to SilcSocketConnection)
6804 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6806 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6807 duplicate packet context structure.
6809 * Changed `notify' client operation to send same arguments as client
6810 receives from server except for ID's. ID's are mapped to correct
6811 ID entry and that is returned. Also, if channel entry is not sent
6812 by server but the notify is for channel the channel entry is sent
6813 to application (otherwise application doesn't know that it is for
6814 channel (library gets it from packet's Destination ID)).
6816 * Added silc_client_remove_from_channels into client library to
6817 remove a client from all channels it has joined to. Used when
6818 received SIGNOFF notify from server. Added also new function
6819 silc_client_replace_from_channels to replace old ID entry with
6820 new ID entry on all channels. Used when received NICK_CHANGE
6823 * Fixed ID Cache list handling in silc_idlist_get_client in
6824 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6825 to get (or query) client by ID.
6827 * Updated TODO list.
6829 * Added connection authentication status message defined by the
6830 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6831 support for these into the code in client and server side.
6833 * Added generic function silc_client_send_command to send any command
6834 with variable argument list. Application should use this function
6835 to send commands if the command functions provided by the library
6836 does not suite for the application's user interface needs.
6838 * Added new `failure' client operation. Application is notified about
6839 received failure packet if client is executing a protocol. In this
6840 case the protocol's execution has failed.
6842 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6843 is required by the protocol.
6845 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6846 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6849 * Added status flag to SilcSKE object to indicate realtime status
6850 of the SKE protocol.
6852 * Application receives now exactly same command reply arguments as
6853 the library receives from server. However, if ID is received the
6854 corresponding ID entry is returned to the application (eg. Client
6855 ID is mapped to correct SilcClientEntry entry and that is returned).
6856 Changed command_reply client operation due to this change.
6858 * Changed all ID's in commands and in command replys as ID Payloads.
6859 Change affected both client and server side codes.
6861 All ID's sent in SILC network (with execption of ID's in SILC
6862 Packet header) are sent in ID Payload to support variable length
6865 * Server now notifies nick changes and notifies all clients on
6866 the channels about the new nickname (about the new Client ID,
6869 * Implemented CMODE command to change channel modes. Supports all
6870 channel modes defined by the protocol specs except ban and invite
6871 lists. (Also, private channel key mode is supported but support for
6872 setting private channel key in client is missing, thus, this mode
6873 has no effect on client side (except that server requires that the
6874 client uses private channel key and normal channel traffic does not
6877 Also, invite mode works per se, but INVITE command does not work
6878 yet correctly, so you can set channel as invite only channel but
6879 inviting clients to the channel does not work (it is yet to be
6880 thought what's the best way to do it).
6882 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6883 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6884 Implemented CUMODE command to change user's mode on the channel.
6885 Supports all modes defined by the protocol specs.
6887 * Added NAMES command reply to return users modes on the channel.
6889 * Removed unnecessary and slow ciphers from lib/silccrypt.
6891 * Set SO_KEEPALIVE option to connection sockets by default.
6893 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6895 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6896 redefined the Notify Payload into protocol specs.
6898 * Added silc_id_payload_parse_id to get ID directly from raw
6901 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6904 accept searching by Client ID as well.
6906 * Added support for LEAVE and SIGNOFF notify types in client library.
6908 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6909 to parse ID Payload from raw data.
6911 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Added flags parameter into silc_ske_assemble_security_properties
6914 function in lib/silcske/silcske.[ch].
6916 * Changed notify client operation to fit better for notify messages
6917 sent by server. The notify payload received from server is now
6918 passed to the application (after parsing it to SilcNotifyPayload).
6919 It is application's responsibility to retrieve the arguments
6920 from the payload and show the message the way it wants. The message
6921 sent by server is implementation specific.
6923 * Changed public keys to comply with the protocol specification.
6924 Old public keys are not supported anymore and are not compatible.
6926 * Removed nickname from Channel Payload as the latest draft removed
6927 it. The client must resolve the nickname from the NAMES command
6928 reply received when it joined the channel.
6930 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6932 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Fixed some errors in protocol specification drafts.
6936 * Created lib/silccore/silcnotify.c to implement Notify Payload
6937 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6938 generic payloads described by protocol specifications. The file
6939 includes implementations for ID Payload and Argument Payload.
6941 * Changed Command Payload implementation to use the new Argument
6942 Payload. Changed command_xxxx_payload to command_payload_xxxx
6943 to comply with SILC coding conventions.
6945 * Added suppport for Argument Payload handling in Notify Payload
6946 implementation as protocol requires it. Added the new support
6947 into server and client lib as well.
6949 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6951 * Added support for multiple nicknames on same channel. [n] is
6952 added locally to the nickname if there are more than one same
6953 nicknames on the channel.
6955 * Server now sends all nicknames that matched WHOIS request.
6956 Client also shows the list received from server.
6958 * Added TOPIC command to client side. User can now set and show
6959 current topic on channel.
6961 * Added MOTD command to client and server. Also, server sends the
6962 motd when client connects to the server.
6964 * Changed version strings to comply ISO 8601.
6966 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Fixed protocol error handling in client library. It should now
6969 cope even if the SKE fails for some reason.
6971 * Made new protocol specification drafts for submitting to IETF.
6973 * Implemented TOPIC command to server in silcd/command.c.
6975 * Added two new notify types into lib/silccore/silcnotify.h:
6976 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6977 notify nickname change and topic setting/change on a channel.
6979 * API change of command_reply operation in client library. The
6980 application gets now the status type received from server as well.
6982 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6986 * Cras fixed and optimized the packet handling even further and
6987 it should work now. Minor change to the prototype of function
6988 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6990 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Added new function into lib/silcutil/silcschedule.[ch]:
6993 silc_schedule_with_fd to select() a specified fd. The function
6994 returns after timeout expires or data arrives or goes. The
6995 function is used by packet routines to wait that all data is
6996 received from network.
6998 * Fixed data reading from network in lib/silccore/silcpacket.c.
6999 The code now assures that all data is read from the fd and then
7000 continues packet processing. This was a bug fix since the code
7001 used to drop some data in some circumstances.
7003 * Added new function into lib/silcclient/client.[ch]:
7004 silc_client_start_key_exchange to start key exchange after
7005 connection has been established to server. The code internally
7006 now uses this funtion but its main purpose was to provide it
7007 for applications that perform their own connecting. After
7008 application has created a connection it merely calls this
7009 function to start the key exchange between client and server.
7010 The library takes care of everything else after that.
7012 Updated also lib/silcclient/README to explain the usage of
7015 * Do not send to application information that connection has
7016 been established. Application gets notified it by connect
7019 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7021 * Applied cras's patch to add silc_schedule_one function. The
7022 function runs scheduler once and returns.
7024 * Fixed the scheduler after cras messed it up. The timeout
7025 handling works now as it's supposed to work.
7027 * Added into lib/silccore/ silcnotify.h to include notify
7028 message types support. Changed silc_server_send_notify*
7029 functions, in server.[ch], to support those new notify types.
7030 Added the support for the notify types into client library,
7031 as well. Added new notify client operation into ops.h in
7034 * Changed silc_server_packet_send_to_channel to send normal
7035 packets instead of just channel message packets. The function
7036 is now used to send the notify packets to channels. It is not
7037 used to send channel message packets anymore, as server never
7040 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7041 va_arg()s as it seems to require it nowadays. I guess, if SILC
7042 is compiled with older va_arg() the new code should work anyway.
7044 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7046 * Splitted core library. Core library (lib/silccore) includes
7047 now only SILC protocol specific core (and common) components.
7048 Created new utility library (lib/silcutil) that includes more
7049 generic purpose stuff. The stuff for util library was taken
7050 from the old core library. This was minor and easy split.
7052 * Created SILC Client Library (lib/silcclient) that includes
7053 implementation of the SILC client without user interface. This
7054 was major move from silc/ directory. The code has been changed
7055 so that it is transparent towards the user interface. The
7056 silc/ directory includes now the same user interface as before
7057 and it uses the new client library. Read lib/silcclient/README.
7058 Basicly, the client library performs everything else related
7059 to SILC except user interface handling. Also, configuration
7060 files are considered to be part of user interface and library
7061 does not handle them.
7063 This change also changed a lot of structures, function naming etc.
7064 Most important change was that SilcClientWindow object was
7065 renamed to SilcClientConnection in the client library. Created
7066 also new file lib/silcclient/ops.h. Also added new files
7067 silc/local_command.[ch] and silc/client_ops.[ch].
7069 All these changes were made to make it easier for user interface
7070 designers to create what ever user interface for the SILC client
7073 It is also expected that the server will be moved to lib
7074 directory as well and SILC Server Library will be created;
7075 sometimes in the future.
7077 * Removed Local commands from lib/silccore/silccommand.h as
7078 they are application specific and new client library does not
7079 handle any of those anymore.
7081 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7082 old client implementation in silc/.
7084 * Added support for callback functions in SILC_LOG_* macros.
7085 Application can now set its own callbacks that will be called
7086 instead of using the default functions that will always print
7087 the debug messages to stderr (or stdout). Also, debugging can
7088 now be disabled by setting silc_debug to FALSE and re-enabled by
7089 setting it to TRUE. Note, that logging will still work even
7090 if debugging is disabled.
7092 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7093 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7094 silc_log_reset_debug_callbacks.
7096 * To enable debugging in silc client one must give now -d
7097 option on command line.
7099 * Changed silc_schedule_init to automatically allocate task queues
7100 if they are not allocated before calling it.
7102 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Added GMP 3.1 into math library.
7106 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7109 a channel in SILC network. The packet is used by servers and
7110 routers to notify other routers that user has left a channel.
7111 This little feature was missing until now. Added the feature
7112 to protocol specification as well.
7114 Added functions: silc_server_send_remove_channel_user and
7115 silc_server_remove_channel_user into server.[ch].
7117 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7118 lib/silccore/silcpacket.h. However, they are not implemented
7121 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Fixed joining to a channel and sending channel messages
7124 between server and router. The channel message sending should
7125 now work inside a cell.
7127 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Fixed the private message sending between server and router.
7130 The private message sending should now work inside a cell.
7132 * Added silc_server_replace_id into server.[ch] to replace
7133 existing ID in the SILC network.
7135 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7136 and silc_idlist_replace_server_id into idlist.[ch] in server.
7138 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Fixed the server to server connections. Server can again now
7141 connect to router. Router to router connections probably does
7144 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Added dynamic protocol registering support. Now protocols can
7147 registered and unregistered on the fly. Patch by cras.
7149 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7151 * Added lib/contrib directory to hold routines that some platforms
7152 don't have but are needed by SILC.
7154 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7155 into lin/contrib to provide getopt() and getopt_long() for
7156 those who don't have it.
7158 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * Added AWAY command to client. When away message is set and
7161 client receives a private message packet the client automatically
7162 replies to the sender with the away message.
7164 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7165 bug seemed to be the cause of recent problems when compiling
7168 * Added version detection support to SKE protocol specification
7169 and added the new changes to the SKE implementation as well.
7170 There were other minor changes in the SKE protocol as well.
7172 Many changes in lib/silcske/silcske.[ch] and in
7173 lib/silcske/payload.[ch].
7175 * Added ^U functionality, clear input line. Patch from cras.
7177 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Mainly small bugfixes on core library. Fixed some debugging
7180 logging and buffer overflow in silclog.c.
7182 * Updated config.sub and config.guess on the distribution tree.
7184 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7186 * Added command lagging support in server. Client may execute
7187 commands now only once in two seconds.
7189 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7191 * Optimized packet reception. MAC computation and checking is now
7192 also more optimized. A lot previously duplicated code is now
7193 used as generic by both client and server.
7195 * Fixed key pair generation in clientutil.c
7197 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Added into lib/silccore/silcbufutil.[ch] new function;
7200 silc_buffer_realloc.
7202 * Moved generic packet sending/encryption functions to
7203 lib/silccore/silcpacket.[ch] from client and server. Some
7204 rewriting of the functions.
7206 * Moved all generic packet reception/decryption functions to
7207 lib/silccore/silcpacket.[ch] from client and server. The
7208 packet processing is now much cleaner in both client and server.
7209 These were major changes in both client and server.
7211 * Created many common functions in server to do packet sending.
7212 Previously code were duplicated a lot, this has been removed
7215 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * Rewrote major parts of the ID cache system. Don't know
7218 whether it is better now or not but at least the API is more
7221 * Major rewrite on ID cache stuff on client because of the ID
7222 cache API changes. Added idlist.c to client.
7224 * Also major rewrite on ID cache stuff on server as well.
7225 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7226 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7227 in hand, instead they are all put into the ID cache system now.
7228 All server_idlist_* routines uses ID cache now instead of
7229 traversing its own lists (those lists does not exist anymore).
7230 SilcIDList though still exists. Also, SilcXXXEntry's are
7233 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Finally made the SKE implementation compliant to the protocol
7236 specification. All mp integers are now binary encoded as
7237 opposed being HEX encoded.
7239 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7242 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7243 functions: silc_[encode/decode]_pem. Also added function
7244 silc_encode_pem_file to PEM encode with newlines ('\n') for
7247 * SILC public keys are now encoded either PEM or binary. Same
7248 option is for private keys as well. By default private keys
7249 are binary encoded and public keys PEM encoded. Silly HEX
7250 encoding were removed.
7252 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7253 function to create fingerprints.
7255 * Fixed a bug in SHA1; does not change the original data anymore.
7257 * Partly implemented INFO command on client and server side.
7258 Fixed CLEAR command. Changes to SERVER command; show current
7259 server(s) when giving command without arguments. Added
7260 VERSION command to client.
7262 * Added check to server that unregistered connections cannot
7263 execute commands (unless it is specificly allowed).
7265 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7267 * Fixed screen refresh.
7269 * Fixed channel joining bug from client. On some circumstances
7270 client tried to join to a channel it had already joined.
7272 * Added public key verification process into client's protocol.c.
7273 The client now verifies the public key from user and saves
7274 it into ~./silc/serverkeys/ directory.
7276 Added into: clientutil.[ch]: silc_client_verify_server_key.
7278 * Changed SKE protocol's silc_ske_initiator_finish function
7279 to accept callback function that verifies the received public
7280 key. Removed old silc_ske_verify_public_key function.
7282 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7284 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7285 silc_pkcs_private_key[_data]_set.
7287 * Made the password and public authentication more cleaner in
7288 server's protocol.c.
7290 * Removed historic and obsolete protocol `channel_auth' from
7291 both client and server.
7293 * Removed wrong way of sending command status messages from
7294 server to client in server's command.c. The old way violated
7295 protocol specification.
7297 Changes to silccore/silccommand.[ch]: removed
7298 silc_command_encode_status_payload -> not needed anymore,
7299 changed silc_command_encode_payload_va to accept extra
7300 argument on variable argument list. The argument type must
7301 now be provided to the function. Also, added new function:
7302 silc_command_encode_reply_payload_va which is same as
7303 normal command_encode_payload_va except command status type
7304 is provided as extra argument.
7306 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Added ~./silc directory handling. The directory includes the
7309 public and private keys for the client.
7311 Added silc_client_check_silc_dir, silc_client_create_identifier
7312 and silc_client_load_keys.
7314 * Implemented SILC protocol compliant public key. Added public
7315 and private key saving to and loading from files.
7317 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7318 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7319 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7320 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7321 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7323 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7324 silc_pkcs_load_[public/private]_key.
7326 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Added silc_server_get_route (route.[ch]) to get connection
7329 data for the fastest route for given ID.
7331 * Implemented INVITE command on client and server. The command
7332 were re-defined in the SILC Protocol Specification and the
7333 implementation now complies with the specification.
7335 * Implemented PING command on client and server.
7337 * Implemented NAMES command on client and server. The server side
7338 supports currently only normal server not router server yet.
7339 Some changes to NAMES definition in SILC protocol specification.
7341 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Implemented LEAVE command on client and server.
7345 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7346 again. This change was made to the protocol as well. Server
7347 should not violate the protocol specification anymore.
7349 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7352 was tested. SOCKS4 was not but should work anyway.
