167 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
169 * ROBOdoc documented the lib/silcske/silcske.h, and improved
170 the SKE interface a bit.
172 * Fixed padding problem in PKCS#1. The padding was not actually
173 random since the random number generator was used incorrectly.
174 This security bug affects only when encrypting with PKCS#1, and
175 it is not currently used at all in SILC. SILC only use signing
176 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

254 Affected files silcd/serverconfig.[c], server.[c].
256 * Splitted the doc/example_silcd.conf.in. Separated the crypto
257 algorithm parts and created new file silcalgs.conf, that
258 is now included from the example_silcd.conf.in.
260 * Optimized the silc_server_connect_to_router_second to take
261 the connection configuration object from the SilcServerConnection
262 object instead of finding it during the connecting phase.
263 Added the configuration object to SilcServerConnection struct.
264 Affected files silcd/server_internal.h, server.c.

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

348 * Fixed the file transfer's key agreement payload to include
349 zero port also if the hostname is NULL because it could not
352 Call file transfer monitor callback now also if error occurs
353 during key agreement protocol.
355 Changed the silc_client_file_send interface to return the
356 SilcClientFileError instead of session id. The session ID
357 is returned into pointer provided as argument.

376 * Fixed the channel message payload decryption in the function
377 silc_channel_message_payload_decrypt to not modify the original
378 buffer before it is verified that the message decrypted
379 correctly. Otherwise, next time it is called with correct
380 channel key it won't encrypt since the payload is corrupted.
381 Affected file lib/silccore/silcchannel.c.
383 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

397 become invalid in the callback but it was referenced after
398 the callback returned.
400 Do not allow auto rehashing of hash table during the
401 silc_hash_table_foreach operation, for same reasons as it is
402 not allowed for SilcHashTableList. Affected files are
403 lib/silcutil/silchashtable.[ch].

426 users list to SilcHashTable. The affected files are
427 lib/silcclient/idlist.[ch].
429 * Fixed a bug in hash table tarversing. While the hash table
430 is traversed with SilcHashTableList the table must not be
431 rehashed. It is now guaranteed that auto rehashable tables
432 are not rehashed while tarversing the list. Also defined that
433 silc_hash_table_rehash must not be called while tarversing
434 the table. Added function silc_hash_table_list_reset that must
435 be called after the tarversing is over. The affected files are
436 lib/silcutil/silchashtable.[ch].
438 * Changed all hash table traversing to call the new
439 silc_hash_table_list_reset in server and in client library.
441 * Added function silc_client_on_channel to return the

457 * When sending JOIN command to router for processing the
458 sender's old command identifier was not saved back to the
459 sender's command context, fixed now. The affected file is
462 * Create the key in JOIN command of the router did not return
463 the channel key, added check for this. Affected file is
466 * Fixed a channel ID update bug in JOIN command reply. Do
467 not directly upgrade the ID but call the function
468 silc_idlist_replace_channel_id if the ID was changed.
469 Affected file silcd/command_reply.c.
471 * Fixed memory leaks from command calling if it would fail.
472 Affected file silcd/command.c.

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

559 local entry will always get the unformatted nickname.
560 Affected file lib/silcclient/idlist.c.
562 * Fixed some double frees from client library commands.
563 Affected file is lib/silcclient/command.c.
565 * Fixed CUMODE command in server to assure that no one can
566 change founder's mode than the founder itself, there was a
567 little bug. Affected file silcd/command.c.
569 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
571 * Removed the SilcClientCommandDestructor from the client
572 libary, it is not needed anymore. Affected files are
573 lib/silcclient/silcapi.h, command[_reply].[ch],
574 client_notify, idlist.c.
576 * Fixed GETKEY command to first resolve client, and then
577 resolve the server only if the client was not found, instead
578 of resolving both at the same time. Affected file is
579 lib/silcclient/command.c.
581 * Added silc_client_start_key_exchange_cb and lookup the
582 remote hostname and IP address before starting the key
583 exchange with server. The affected file is
584 lib/silcclient/client.c.
586 * The server's public key is now saved using the IP address
587 of the server and not the servername for the filename.
588 The hostname public key filename is checked as an fall back
589 method if the IP address based filename is not found.
591 Fixed the GETKEY command to save the fetched server key
594 Print the remote server's hostname now when new key is
595 received during connection process. Affected file is
596 irssi/src/silc/core/client_ops.c.
598 * Return always our own public key to the client if it asks
599 for it with GETKEY command. Affected file silcd/command.c.
601 * Removed the use_auto_addr variable from default config
602 file since it was in wrong section. Affected file is
605 * Fixed TOPIC_CHANGE notification to not route it when it
606 was sent using silc_server_send_notify_to_channel function.
607 Affected file silcd/command.c.
609 * Fixed silc_server_send_notify_kicked to send the kicker's
610 Client ID also, it was missing. Affected files are
611 silcd/command.c, silcd/packet_send.[ch].
613 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Do not save client history information in SERVER_SIGNOFF.
616 Fixes the bug in normal server that it does not detect
617 the client becoming valid after the server becomes back
618 online. Affected file silcd/server_util.c.
620 * Added `sock_error' field into the SilcSocketConnection
621 context. When error occurs during socket operation (read
622 or write) the error is saved. Added also new function
623 silc_socket_get_error to return human readable socket error
624 message. Affected files are lib/silcutil/silcsockconn.[ch],
625 lib/silcutil/unix/silcunixsockconn.c, and
626 lib/silcutil/win32/silcwin32sockconn.c.
628 * The server now prints the socket error message in the
629 signoff for client. Affected file silcd/server.c.
631 * Fixed the `created' channel information sending from router
632 to server in JOIN command. Checks now whether the channel
633 really was created or not and set it according that.
635 Fixed the JOIN command to use the client entry's current
636 ID during the joining procedure instead of the one it sent
637 in the command (it is checked though), since it can change
638 between the packet processing and command processing, and
639 would just case unnecessary pain in the client end. Affected
640 file silcd/command.c.
642 * Fixed a channel key payload sending to use correct channel
643 ID when the server was forced to change the channel's ID by
644 router. Router sent the key payload with the old Channel ID.
645 Affected file silcd/packet_receive.c.
647 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Call silc_server_save_channel_key only if the key payload
650 was provided in the JOIN command's command reply. Affected
651 file silcd/command_reply.c.
653 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
655 * Fixed silc_mp_sizeinbase to return the value correctly with
656 MPI. Affected file lib/silcmath/mp_mpi.c.
658 * Fixed the stop_server signal to correctly stop the scheduler
659 and gracefully stop the server when SIGTERM or SIGINT signals
660 are received. Affected file silcd/silcd.c.
662 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
664 * Simple handling of TERM and HUP signals. Also added some log
665 flushing call around. Affected file is
668 * Fixed small bugs in silclog.c. Now buffering output will take
669 effect after 10 seconds since startup: This will ensure that
670 no important startup messages are lost. Also output redirection
671 will preserve original format ([Date] [Type] message).
672 Affected file is lib/silcutil/silclog.c.
674 * Added two options to the config file, in the logging section:
675 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
676 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
678 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
680 * Do not print the warning about log files not being initialized
681 more than once to avoid excess logging. Affected file is
682 lib/silcutil/silclog.c.
684 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
685 the SIM copying in make install in Makefile.am.pre.
687 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
689 * Rewritten silclog APIs. Globally interesting changes follows:
690 silc_log_set_files() changed to silc_log_set_file().
691 silc_log_set_callbacks() changed to silc_log_set_callback().
692 ROBOdoc documented silclog header file.
693 SilcLogCb now returns bool to wether inihibit the default
694 handler or not (to keep the old behaviour return always TRUE).
695 The new APIs should also fix the problem of the
696 silcd_error.log file that was written in the current directory.
699 Log files streams will remain opened after silc_log_set_file()
700 call, means less CPU usage notably on high traffic servers.
701 File streams are now full buffered, and flushed to the disk
702 every 5 minutes, lesses HD activity and CPU usage.
703 Messages can be redirected, allowing admins to configure
704 one single logfile for all server messages.
705 the silc_log_quick global variable to activate fast-logging.
706 Affected files lib/silcutil/silclog.[ch]
708 * Changed some code to conform new silclog APIs. Affected
709 files are doc/example_silcd.conf.in, silcd/server.c
710 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
713 * Fixed a memory leak that could occur in some situations.
714 Affected file silcd/serverconfig.c.
716 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
718 * Added the silc_client_del_client to remove the client from
719 all channels as well. Affected file lib/silcclient/idlist.c.
721 * Fixed the client library to correctly remove the client
722 from all channels when the client entry is being destroyed.
723 Affected file lib/silcclient/client_notify.c, command.c.
725 * Added auto-nicking support to the client library. If the
726 applicatio now sets client->nickname it will be sent to the
727 server after connecting by the library. This way for example
728 SILCNICK (or IRCNICK) environment variables will have effect
729 and always change the nickname automatically to whatever
730 it is wanted. Affected file lib/silcclient/client.[ch].
732 * Renamed silc_server_command_bad_chars to the
733 silc_server_name_bad_chars and moved it to the
734 silcd/server_util.[ch]. Added also new function
735 silc_server_name_modify_bad to return nickname that
736 includes bad characters as new nickname without those
737 bad characters. This check and modify is now used in
738 silc_server_new_client when the username is initially set
739 as nickname, so it must be checked to be valid nickname.
740 Affected file silcd/packet_receive.c.
742 * The nickname length is now taken from the packet for real
743 and not trusted to strlen() since it clearly can return
744 wrong length for nickname including bad characters. This
745 also applies to channel names. Affected file silcd/command.c.
747 * Removed the lib/silcsilm/modules directory. Modules are now
748 compiled into the lib/silcsim. Fixed the copying of the
749 modules to follow symbolic links in Makefile.am.pre.
751 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
753 * Fixed silc_string_regexify list creation. Fixes bugs with
754 BAN and INVITE commands in server. The affected file is
755 lib/silcutil/unix/silcunixutil.c.
757 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
759 * Removed the command destructor entirely from the server's
760 command and command reply routines. It is not needed, and
761 its usage was buggy and caused crashes. Affected files are
762 silcd/command[_reply].[ch].
764 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
766 * Cancel protocol and NULL sock->protocol if timeout
767 occurred during protocol. Affected file silcd/server.c.
769 * Cancel protocol timeouts always before calling the final
770 callback, to assure that after final callback is called
771 no other state will be called for the protocol anymore.
772 Affected file silcd/protocol.c.
774 * Print error log if incoming connection configuration could
775 not be found. Affected file silcd/server.c.
777 * Fixed JOIN command to correctly save the founder mode
778 to the client on normal SILC server, when the channel
779 was created by the router. Affected file silcd/command.c.
781 * Fixed LIST command (hopefully) to send correct reply
782 packets. Affected file silcd/command.c.
784 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
786 * The silc_packet_receive_process now returns FALSE if the
787 read data was invalid packet, and TRUE if it was ok.
789 The server now checks that if unauthenticated connection
790 sends data and its processing fails the server will close
791 the connection since it could be a malicious flooder.
793 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
795 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
797 * Make sure the warning about error opening a log file is
798 printed only once and not everytime it fails (produces
799 too much useless log). Affected file lib/silcutil/silclog.c.
801 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
803 * Made the silc_server_daemonise() function more readable.
804 Affected file silcd/server.c.
806 * Pid file is now optional, the user may comment it out from
807 the config file. Removed define SILC_SERVER_PID_FILE, we
808 don't need a default any longer. Affected file
809 configure.in.pre, lib/Makefile.am.pre.
811 * Make some use of the pid file. The server now dies at startup
812 if it detects a valid pid file on his path. The server would
813 die anyway in this circumstance, because of the bind() failure.
814 Affected file silcd/silcd.c.
816 * No longer compiling lib/dotconf.
818 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
820 * Fixed JOIN command parsing not to crash. Affected file
821 lib/silcclient/command.c.
823 * Fied the NICK_CHANGE notify to add the new client entry
824 even it is resolved. This removes an <[unknown]> nick
825 thingy bug in the client. Affected file is
826 lib/silcclient/client_notify.c.
828 * Do not try to allocate 0 bytes (efence does not like it)
829 in lib/silccore/silccomand.c when encoding payload.
831 * Do not take IRCNICK as nickname in Irssi SILC client since
832 it is not possible to set nickname before hand connecting
833 the server (TODO has an entry about adding auto-nicking
836 * Changed the silc_server_command_pending to check whether
837 there already exists an pending entry with the specified
838 command, command identifier and pending callback. This is
839 to fix IDENTIFY and WHOIS related crashes that may register
840 multiple pending commands with same identifier. Affected
841 file silcd/command.c.
843 * Fixed the server to reconnect to the router even if it
844 was already reconnecting and EOF was received. This to
845 fix a possibility that the server wouldn't ever try to
846 auto-reconnect to the router. Affected file silcd/server.c.
848 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Fixed the server's password authentication to use the
851 length of the locally saved password, and not the one
852 sent in the packet. Affected file silcd/protocol.c.
854 * Fixed same password authentication problem in the
855 Authentication Payload handling routines in
856 lib/silccore/silcauth.c.
858 * Yet another password authentication problem fixed with
859 channel password handling in silcd/command.c.
861 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
863 * If first character of string in silc_parse_userfqdn is '@'
864 then do not parse it. Affected file is
865 lib/silcutil/silcutil.c.
867 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
869 * Fixed minor bug in IDENTIFY command reply sending, which
870 caused various weird problems during JOIN when it was
871 resolving names for users. Affected file silcd/command.c.
873 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
875 * Fixed the IDENTIFY command reply sending to chech better valid
876 clients. It was possible to send incomplete list of replies.
877 Affected file silcd/command.c.
879 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
881 * Added silc_client_command[s]_[un]register functions now to
882 dynamically register the commands in client library. Removed
883 the static table of commands. This allows the client library
884 to call commands without causing the application to know about
885 what commands library has called.
887 Removed the INFO command reply kludge to detect when the command
888 was called by library. Now library use its own command reply
889 function for INFO command.
891 Added function silc_client_command_call to call a command.
892 Application can use it to call command, not access the structure
895 Now all commands that are sent by the client library (not
896 explicitly sent by application) use own command reply functions.
898 Affected files around lib/silcclient/ and in
899 irssi/src/silc/core/.
901 * Fixed the WHOIS command reply sending to chech better valid
902 clients. It was possible to send incomplete list of replies.
904 Fixed the WHOIS and IDENTIFY to send the request to router
905 if normal server did not do it and did not find any results.
907 Affected file silcd/command.c.
909 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
911 * Moved the internal data from SilcClient context into its
912 own file, not accesible to application. Affected files
913 lib/silcclient/client.h and lib/silcclient/client_internal.h,
914 and other files in client library.
916 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Added doc/examples installation target in Makefile.am.pre.
921 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
923 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
924 commands the found client entry will be removed from the
925 cache, after notifying application about the error. Affected
926 file lib/silcclient/command_reply.c.
928 * Changed the /MSG to check for exact nickname user gave, and
929 not let `nick' match `nick@host' if it is only one found. Now,
930 user must type the exact nickname (like nick@host2) even if
931 there are no more than one same nicks found. This is to avoid
932 a possibility of sending nickname to wrong nickname since
933 `nick' could match `nick@host'. Affected file is
934 irssi/src/core/silc-servers.c.
936 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Do not print "you are now server operator" or similar when
939 giving /away command. Affected files are
940 irssi/src/silc/core/client_ops.c, silc-servers.h.
942 * Made the silc_server_command_pending_error_check to send
943 the same command reply payload it received back to the
944 original sender of the command. This way all arguments
945 that was received by the server will be received by the
946 client too. Affected file silcd/command.c.
948 * Added the silc_idcache_add to return the created cache entry
949 to a pointer. Affected file lib/silccore/silcidcache.[ch].
951 * Add global clients to expire if they are not on any channel.
952 This is because normal server will never know if they signoff
953 if they are not on any channel. The cache expiry will take
954 case of these entries. This is done by normal servers only.
955 The affected files are silcd/command_reply.c,
956 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
958 * If server receives invalid ID notification for WHOIS or
959 IDENTIFY and the ID exists in the lists, it is removed.
960 Affected file silcd/command_reply.c.
962 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
963 in client then client entry that it matches is searched and
964 the nickname is printed on the screen for user. Affected
965 file irssi/src/silc/core/client_ops.c.
967 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
969 * Use cache entry expire time in the LIST command reply to
970 purge old entries from the cache after the LIST command
971 reply has been received. This way we don't have non-existent
972 entries in the cache for too long. Affected file is
973 silcd/command_reply.c.
975 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
977 * If we are normal server, and we've not resolved client info
978 in WHOIS or IDENTIFY from router, and it is global client,
979 we'll check whether it is on some channel. If it is not
980 then we cannot be sure about its validity and will resolve it
981 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
982 file silcd/command.c.
984 * Search channel by name (if possible) rather than by ID
985 in IDENTIFY command's command reply. Affected file is
986 silcd/command_reply.c.
988 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
990 * Distribute to the channel passphrase in CMODE_CHANGE notify.
991 Updated specs and implemented it. Affected file silcd/command.c,
992 silcd/packet_send.c and silcd/packet_receive.c.
994 * Implemented the <founder auth> payload handling in the JOIN
995 command. If provided all conditions for channel joining
996 except requirement to provide correct passphrase can be
997 overrided by the channel founder. Updated the protocol specs.
998 Affected file silcd/command.c.
1000 Added support for founder auth in JOIN command in client
1001 library. Fixed the parsing of the JOIN command now to support
1002 all options as they should be. The affected file is
1003 lib/silcclient/command.c.
1005 * Optimized the WHOIS and IDENTIFY commands to send the request
1006 to router only if it includes nicknames or other names. If
1007 they include only IDs then check the local cache first before
1008 routing. Affected file is silcd/command.c.
1010 * Added channels topic announcements. Affected file is
1011 silcd/packet_receive.c and silcd/server.c.
1013 * Fixed the silc_server_send_notify_topic_set to really destine
1014 the packet to channel. Affected file silcd/packet_send.c.
1016 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1017 library. Affected file lib/silcclient/client_notify.c.
1019 * Added UMODE announcements. Affected file silcd/server.c.
1021 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Memory leak fixes in:
1025 lib/silcutil/silcsockconn.c
1026 lib/silcske/silcske.c
1027 lib/silcske/groups.c
1029 lib/silccrypt/silcpkcs.c
1030 lib/silccore/silccommand.c
1031 lib/silccore/silcidcache.c
1036 * ROBOdoc documented the lib/silcske/groups.h file and a
1037 bit changed the interface for better.
1039 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1041 * Update the client entry context in the ID cache after
1042 nick change. Affected file lib/silcclient/command.c.
1043 Fixes the CUMODE command when regaining founder privileges,
1044 and a little WHOIS problem.
1046 * Fixed silc_net_gethostbyname to correctly call the
1047 inet_ntop. Affected file lib/silcutil/silcnet.c.
1049 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1051 * Added IPv6 support checking to the configure.in.pre, added
1052 also --enable-ipv6 option to override the check. Affected
1053 file configure.in.pre.
1055 * The silc_thread_create now calls the start function
1056 directly if threads support is not compiled in. Removes
1057 ugly #ifdef's from generic code. Affected files are
1058 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1060 * Added silc_net_gethostby[name/addr]_async to asynchronously
1061 resolve. Affected files are lib/silcutil/silcnet.[ch].
1063 * Added support for rendering IPv6 based server, client and
1064 channel IDs. Affected file lib/silcutil/silcutil.c.
1066 * Added support for creating IPv6 based server IDs. Affected
1067 file is silcd/serverid.c.
1069 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1071 * Added silc_net_gethostby[addr/name] into the
1072 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1073 routines. Added silc_net_is_ip[4/6]. Affected file is
1074 lib/silcutil/unix/silcunixnet.c. All routines that take
1075 address as argument now supports both IPv4 and IPv6 addresses.
1077 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1079 * Fixed LIST command reply sending in server. Affected file
1082 * Server now sends the kicker's client ID in the KICK notify
1083 to the kicked client. Affected file silcd/command.c.
1085 * The client library now parses the kickers client ID and
1086 UI displays it. Affected files lib/silcclient/client_notify.c
1087 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1089 * Made all payload parsing function prototypes consistent.
1090 They all take now const unsigned char * and uint32 pair as
1091 the payload data instead of SilcBuffer. Changes all around
1092 the source tree. Other unsigned char* -> const unsigned char*
1093 changes around the tree as well.
1095 * Optimized SFTP client and server packet sending not to
1096 allocate new buffer for each packet but to recycle the
1097 first allocated buffer. Affected files are
1098 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1100 * Optimized the SFTP client to use SilcList instead of
1101 SilcDList for requests, because it is faster. Affected file
1102 is lib/silcsftp/sftp_client.c.
1104 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1105 into lib/silccore/silcid.[ch].
1107 Renamed silcpayload.[ch] into silcargument.[ch].
1109 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1111 * If client entry is deleted with active key agreement
1112 session, abort the session.
1114 The silc_client_abort_key_agreement now calls the completion
1115 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1117 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1120 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Don't use __restrict in older GCC's. Affected file is
1123 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1125 * silc_net_localhost now attempts to reverse lookup the
1126 IP/hostname. Affected file lib/silcutil/silcnet.c.
1128 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1129 command. It can be used to gain founder privileges at
1130 the same time when joining the channel.
1132 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1133 kicker's client ID as well. Updated protocol specs.
1135 Defined that the server must send SILC_COMMAND_IDENTIFY
1136 command reply with error status to client who sent
1137 private message with invalid client ID.
1139 Updated the protocol specification.
1141 * Added silc_server_send_command_reply to send any
1142 command reply. Affected file silcd/packet_send.[ch].
1144 * Added silc_id_payload_encode_data to encode ID payload
1145 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1147 * The server now send IDENTIFY command reply with error
1148 status if client ID in private message is invalid. Affected
1149 file silcd/packet_receive.c.
1151 * Save the server key file with server's IP address in
1152 the filename instead of hostname. The affected file is
1153 irssi/src/silc/core/client_ops.c.
1155 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1160 * Added libtool support for compiling shared objects in
1161 lib/silcsim. Affected file configure.in.pre and
1162 lib/silcsim/Makefile.am. Original patch by cras.
1164 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * Pid file configuration, and server's config file fixes
1167 patch by toma. Updated CREDITS file.
1169 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Fixed silc_client_channel_message to not try to decrypt
1172 the message twice if it resolved the destination client
1173 information. This could cause of dropping one channel
1174 message. Affected file lib/silcclient/client_channel.c.
1176 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1179 lib/silcclient/client.c. This function is used when the SILC
1180 Client is run under some other scheduler, or event loop or
1181 main loop. On GUI applications, for example this may be
1182 desired to used to run the client under the GUI application's
1183 main loop. Typically the GUI application would register an
1184 idle task that calls this function multiple times in a second
1185 to quickly process the SILC specific data.
1187 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1189 * Fixed silc_server_drop() for dropping the supplementary
1190 groups as well, this could cause a security hole on some
1193 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1195 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1198 * Write PID file after dropping privileges. Added -F option
1199 to run server on foreground. A patch by debolaz.
1200 Affected files silcd/server.c, silcd/silcd.c.
1202 * Fixed MOTD to return the MOTD file server name. Affected
1203 file silcd/command.c.
1205 * Added INFO command reply handling to the Irssi SILC Client.
1206 Affected file irssi/src/silc/core/client_ops.c.
1208 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Fixed the silc_idcache_list_* routines to really support
1211 the dynamic list. Fixes a crash. Affected file is
1212 lib/silccore/silcidcache.c.
1214 * Fixed the LIST command reply to really call LIST command's
1215 pending callbacks. Affected file silcd/command_reply.c.
1217 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Update conn->local_entry->nickname after giving NICK
1220 command. Affected file lib/silcclient/command.c.
1222 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1224 * Added the [pid] option to the silcd configuration file
1226 Affected files: serverconfig.[ch] and silcd.c
1228 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Save fingerprint in WHOIS command reply in server.
1231 Affected file silcd/command_reply.c.
1233 * Fixed NICK commands pending callback registration.
1234 Affected file lib/silcclient/command.c.
1236 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * Use ++server->cmd_ident when sending commands in server,
1239 instead of random number. Affected file silcd/command.c.
1241 * Fixed GETKEY command reply to call actually GETKEY pending
1242 command callbacks. Affected file silcd/command_reply.c.
1244 * A bit stricter check for nicknames. Check for same nickname
1245 in NICK command also. Affected file silcd/command.c.
1247 * Do not call INFO command everytime client ID changes, only
1248 during first connecting. Affected file lib/silcclient/client.c.
1250 * Set the new nickname only after successful command reply for
1251 NICK command is returned by server. Affected file
1252 lib/silcclient/command.c.
1254 * Remove nicknames from nicklist during server_signoff notify.
1255 Should fix /NAMES bit more. The affected file is
1256 irssi/src/silc/core/silc-channels.c.
1258 * Added `fingerprint' field to the SilcIDListData in the
1259 silcd/idlist.h to hold the fingerprint of the client's
1262 Send the fingerprint of the client's public key in WHOIS
1265 Affected files silcd/command.c, and silcd/idlist.[ch].
1267 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1268 create fingerprint from given data.
1270 * Show the fingerprint of the client's public key in WHOIS.
1271 Affected files irssi/src/module-formats.[ch] and
1272 irssi/src/silc/core/client_ops.c.
1274 * Format the multiple same nicknames also during JOIN and
1275 NICK_CHANGE notifys. Affected file is
1276 lib/silcclient/client_notify.c.
1278 * Do not print error on screen for invalid private message
1279 payload since it can come if someone is sending private
1280 messages with wrong key. Affected file
1281 lib/silccore/silcprivate.c.
1283 * Fixed multiple concurrent /PING crash. Affected file
1284 lib/silcclient/command.c.
1286 * Changed the wrong ID encoding. All IP addresses must be
1287 in MSB first order in encoded format. They were encoded
1288 wrong and was in LSB format. Affected files are
1289 silcd/serverid.c, lib/silcutil/silcutil.c.
1291 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1293 * Call the `connect' client operation through the scheduler
1294 in case of error. Affected file lib/silcclient/client.c.
1296 * Call the `failure' client operation even if the error
1297 occurred locally during a protocol. Affected file is
1298 lib/silcclient/protocol.c.
1300 * Added support of sending LIST command to router from normal
1301 server. This way normal server can get list of all channels
1302 in the network too. Fixed the channel list sending in the
1303 server too. Affected files are silcd/command.c, and
1304 silcd/command_reply.[ch].
1306 * Added silc_server_update_channels_by_server and
1307 silc_server_remove_channels_by_server. They are used during
1308 disconnection of primary router and in backup router protocol.
1309 Affected file silcd/server_util.[ch], silcd/server.c and
1310 silcd/server_backup.c.
1312 * Fixed channel adding to global list in IDENTIFY command
1313 reply in server. Affected file silcd/command_reply.c.
1315 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * If the incoming packet type is REKEY or REKEY_DONE process
1318 that packet always synchronously. Fixes yet another MAC
1319 failed error on slow (dialup) connections. Affected file
1320 lib/silcclient/client.c and silcd/server.c.
1322 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1324 * Call check_version SKE callback for initiator too. Affected
1325 file lib/silcske/silcske.c.
1327 * Implemented fix for security hole found in the SKE that was
1328 fixed in the specification few days back; the initiator's
1329 public key is now added to the HASH value computation.
1330 Added backwards support for the old way of doing it too, for
1331 old clients and old servers. Affected file is
1332 lib/silcske/silcske.c.
1334 * Enabled mutual authentication by default in SKE. If initiator
1335 is not providing mutual authentication the responder will
1336 force it. This will provide the proof of posession of the
1337 private key for responder. The affected files are
1338 lib/silcclient/protocol.c and silcd/protocol.c.
1340 * Do not cache anymore the server's public key during SKE.
1341 We do mutual authentication so the proof of posession of
1342 private key is done, and if the server is authenticated in
1343 conn auth protocol with public key we must have the public
1344 key already. Affected file silcd/protocol.c.
1346 * Added new global debug variable: silc_debug_hexdump. If
1347 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1348 file lib/silcutil/silclog.[ch].
1350 * Fixed compilation warning due to char * -> const char *.
1351 Affected files lib/silcutil/silcnet.h, and
1352 lib/silccore/silcauth.[ch].
1354 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Fixed CMODE command when new channel key was created. If
1357 the creation failed the old key was removed. Next time giving
1358 same command would crash the server since the old key was
1359 freed already. Affected file silcd/command.c.
1361 * Fixed the silc_server_announce_get_channels to not crash
1362 on reconnect. Affected file silcd/server.c.
1364 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Added silc_log_set_debug_string function to set a regex
1367 string to match for debug output. Only the function names,
1368 or filenames matching the given debug string is actually
1369 printed. This way it is possible to filter out those debug
1370 strings that user is not interested in.
1372 Fixed a bug in silc_string_regexify.
1374 Affected files lib/silcutil/silclog.[ch], and
1375 lib/silcutil/unix/silcunixutil.c.
1377 * Changed the -d options in both server and Irssi SILC client
1378 to take the debug string as argument. Affected files
1379 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1381 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * Added silc_hash_babbleprint to create a Bubble Babble
1384 Encoded fingerprint. The encoding is developed by Antti
1385 Huima (draft-huima-babble-01.txt), and it creates human
1386 readable strings out of binary data. Affected file
1387 lib/silccrypt/silchash.[ch].
1389 * Print the babble print now in addition of fingerprint as well
1390 in Irssi SILC client. Affected files are
1391 irssi/src/fe-common/silc/module-formats.[ch],
1392 irssi/src/fe-common/silc/core/client_ops.c.
1394 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Fixed a security problem found in SKE. The initiator's
1397 public key too is now added to the HASH hash value creation
1398 which is signed by the responder to create the SIGN value.
1399 This will prevent anyone in the middle to lie to the responder
1400 about the initiator's public key. If this is done now, the
1401 man in the middle will get caught. Updated the protocol
1404 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Better installation directory handling. Configure module
1407 paths and other paths automatically to example_silc* files
1408 in doc/. A patch by toma.
1410 * Fixed compiler warning from MPI library, and from SILC RNG.
1413 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1414 It can be configured with ./configure. A patch by toma.
1416 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Find correct make to use in prepare-clean. A patch by
1419 toma. Affected file prepare-clean.
1421 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1423 * Added irssi variables use_auto_addr, auto_bind_ip,
1424 auto_bind_port and auto_public_ip.
1426 * Changed the interface for silc_client_send_key_agreement
1427 in lib/silcclient/silcapi.h
1431 irssi/src/silc/core/silc-core.c
1433 lib/silcclient/silcapi.h
1434 irssi/src/silc/core/silc-channels.c
1435 lib/silcclient/client_keyagr.c
1438 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Added silc_pkcs_public_key_compare to compare two
1441 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1443 * Check that the client who set the founder mode on the
1444 channel is the same client that is giving the founder
1445 mode to itself. It is done by comparing the saved public
1446 key (it is saved even in the authentication is passphrase).
1447 Affected file silcd/command.c.
1449 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Do not process packet for disconnected socket connection.
1452 Affected file lib/silccore/silcpacket.c.
1454 * Process the DISCONNECT packet through scheduler in the
1455 client library. Affected file lib/silcclient/client.c.
1457 * Fixed the silc_client_packet_parse to not to increase
1458 the packet sequence number if the conn->sock and the
1459 current socket connection is not same. This can happen
1460 for example during key agreement when the conn includes
1461 multiple socket connections (listeners). Affected file
1462 lib/silcclient/client.c.
1464 * The sender of the file transfer request now provides also
1465 the pointer (listener) for the key exchange protocol. If
1466 the listener cannot be created then it sends empty key
1467 agreement and lets the receiver provide the listener.
1469 Added `local_ip' and `local_port' arguments to the
1470 silc_client_file_send. If they are provided they are used,
1471 if not then it will attempt to find local IP address, if
1472 not found or bind fails then the remote client will provide
1475 Affected files are lib/silcclient/client_ftp.c and
1476 lib/silcclient/silcapi.h.
1478 * Extended the FILE SEND command to support defining the
1479 local IP and port for key exchange listener. They are
1480 optional. Affected file irssi/src/silc/core/silc-servers.c.
1482 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Defined to WHOIS command reply the sending of fingerprint
1485 of the client's public key (if the proof of posession of the
1486 corresponding private key is verified by the server).
1487 Updated to the protocol specification.
1489 * Added support of receiving the client's public key's
1490 fingerprint in command reply in client library. Affected
1491 file is lib/silcclient/command_reply.c, and
1492 lib/silcclient/idlist.[ch].
1494 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Do not send over 128 chars long nickname to the server
1497 in NICK command. Affected file lib/silcclient/command.c.
1499 * Do not send over 256 chars long channel names to the server
1500 in JOIN command. Affected file lib/silcclient/command.c.
1502 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Assure that silc_server_close_connection cannot be called
1505 twice for same socket context. Affected file is
1508 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Send error message to application if opening file for
1511 writing during file transfer fails. Affected file is
1512 lib/silcclient/client_ftp.c.
1514 Remove all file transfer sessions for a client that we're
1515 removing from ID cache.
1517 Affected file is lib/silcclient/client_ftp.c.
1519 * Fixed silc_net_addr2bin to return correct address. Affected
1520 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1522 * Fixed file transfer session removing on signoff notify.
1523 Affected file irssi/src/silc/core/silc-servers.c.
1525 * Added the SilcClientFileError to be returned in the monitor
1526 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1527 Affected file lib/silcclient/silcapi.h.
1529 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Fixed a crash in silc_client_ftp_free_sessions and
1532 silc_client_ftp_session_free_client. Affected file
1533 lib/silcclient/client_ftp.c.
1535 * Added `disabled' field in the SilcChannelEntry in the server
1536 to indicate if the server entry is disabled. Affected file
1537 silcd/idlist.h, silcd/command[_reply].c.
1539 * SILC server adds now /var/run/silcd.pid everytime it is
1540 started. Affected file silcd/silcd.c.
1542 * Added silc_server_packet_send_clients to send a packet to
1543 the provided table of client entries. Affected file
1544 silcd/packet_send.[ch].
1546 * Fixed a crash in client resolving in client_prvmsg.c in
1547 client library. Affected file lib/silcclient/client_prvmsg.c.
1549 * Do not actually remove the client directly from ID cache
1550 during SERVER_SIGNOFF, but invalidate it. This way we
1551 preserve the WHOWAS info for the client. Affected file
1552 silcd/server_util.c.
1554 * Fixed SERVER_SIGNOFF notify handling in the server. The
1555 server is now able to process incoming SERVER_SIGNOFF notify
1556 for a server that it doesn't even know about. It will remove
1557 the clients provided in the notify. Affected file
1558 silcd/packet_receive.c.
1560 * Check for partial packet in data queue after every packet that
1561 was found from the queue. Return and wait for more data if
1562 there is partial data in queue. Affected file is
1563 lib/silccore/silcpacket.c.
1565 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Added SilcClietFileError enum to indicate error in
1568 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1569 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1570 Affected files lib/silcclient/silcapi.h and
1571 lib/silcclient/client_ftp.c.
1573 * Check that newsize in silc_buffer_realloc is larger than
1574 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1576 * Added better monitor of file transfers. It now monitors
1577 key agreement protocol during the file transfer too. Added
1578 error reporting too. Affected files
1579 irssi/src/silc/core/silc-servers.c,
1580 irssi/src/fe-common/silc/module-formats.[ch].
1582 * Wrote a help file for FILE command.
1584 * Added silc_rng_global_get_byte_fast to get not-so-secure
1585 random data as fast as possible. Random data is read from
1586 /dev/urandom if available and from the SILC RNG if not
1587 available. It is used in padding generation. Affected file
1588 lib/silccrypt/silcrng.[ch].
1590 * All packets in client library are now processed synchronously.
1591 Optimized packet processing a lot. Affected file
1592 lib/silcclient/client.c.
1594 * All server connection packets are processing synchronously
1595 now in server, to optimize packet processing. Affected file
1598 * Include files are installed now only in Toolkit distribution
1599 if make install is given. Affected files: all Makefile.am's.
1601 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Assure that silc_client_notify_by_server_resolve does not
1604 resolve the client information multiple times. If it cannot
1605 be found by the first it cannot be found at all. Affected
1606 file lib/silcclient/client_notify.c.
1608 * Fixed WHOWAS command reply calling. Affected file
1609 lib/silcclient/command_reply.c.
1611 * Removed all references to silc_idlist_get_client from the
1612 Irssi SILC client since that call is internal call used by
1613 the library. The Irssi SILC client will use now client
1614 retrieval functions found in silcapi.h.
1616 * Fixed a bug in resolving nickname info before sending
1617 private message. It used freed memory. Affected file
1618 irssi/src/silc/core/silc-servers.c.
1620 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1622 * Assure my_channels statistics cannot go negative in server.
1623 Affected files silcd/server.c, silcd/server_util.c.
1625 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1627 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1629 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * Win32 Toolkit changes. Affected files
1632 win32/silc.dsw, win32/libsilc/libsilc.def,
1633 win32/libsilcclient/libsilc.def,
1634 lib/silcutil/silcutil.c, and
1635 lib/sftp/sftp_fs_memory.c.
1637 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * Added silc_net_localip to return local host's IP address.
1640 Affected file lib/silcutil/silcnet.[ch].
1642 * If key exchange or rekey protocol is active for a connection
1643 parse all packets syncronously since there might be packets
1644 in packet queue that we are not able to process without first
1645 processing packets before them. Affected file silcd/server,
1646 lib/silcclient/client.c.
1648 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1649 whether library should continue processing the packet.
1650 Affected file lib/silccore/silcpacket.h.
1652 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1653 SilcSFTPMonitorData to SFTP server to monitor various

1681 lib/silcutil/silcutil.[ch].
1683 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Resolve the client info when received private message or
1686 channel message for a client which nickname we don't know.
1687 Affected files lib/silcclient/client_prvmsg.c and
1688 lib/silcclient/client_channel.c.
1690 * Do not crash in /KEY if client is not connected. Affected
1691 file irssi/src/silc/core/silc-channels.c.

1696 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1697 is incomplete and is being resolved, it won't be resolved
1700 Make sure also that USERS command reply does not resolve
1701 twice information. Affected file is
1702 lib/silcclient/command_reply.c.
1704 Make sure that silc_client_get_clients_by_list does not
1705 resolve twice same information.
1707 * Check for valid client->id in the silc_server_free_client_data.
1708 Affected file silcd/server.c.
1710 * Fixed /GETKEY nick@server not to crash if the server entry
1711 is not found. Affected file lib/silcclient/command.c.
1713 * Fixed the silc_server_check_cmode_rights to check the
1714 requested modes correctly. Affected file silcd/command.c.

1718 * Better checks for non-printable chars in nick added.
1719 Affected file silcd/command.c.
1721 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * Call the silc_server_udpate_servers_by_server in the
1724 primary router that comes back online in the backup resuming
1725 protocol. Otherwise it routes packets wrong. Affected file
1726 silcd/server_util.[ch], silcd/server_backup.c.
1728 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1730 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1731 lib/silcutil/silcbuffmt.[ch].
1733 * Redefined the SILC packet header to include the padding
1734 length. Affected file lib/silccore/silcpacket.[ch].
1736 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1737 length for maximum padding up to 128 bytes). Affected
1738 file lib/silccore/silcpacket.h.
1740 * Removed all backwards support for old 0.5.x MAC thingies.
1741 The SILC packet header change makes it impossible to be
1742 backwards compatible.
1744 * Send the ENDING packet with timeout in the backup resuming
1745 protocol. This is to assure that all routers has connected
1746 to the primary router. Affected file silcd/server_backup.c.
1748 * Changed the RNG to take the first IV from random data. It
1749 used to take it from zero actually. Changed the RNG also
1750 to use /dev/urandom during session. /dev/random is used
1751 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1753 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Changed the SILC packet header to have the first two bytes
1756 (the packet length) encrypted. Affected files aroung the
1757 code tree, lib/silccore/silcpacket.[ch]. Removed the
1758 SilcPacketCheckDecrypt callback. It is not needed anymore
1759 since the silc_packet_receive_process will determine now
1760 whether the packet is normal or special.
1762 * Implemented the unidirectional MAC keys. Affected files
1763 lib/silcske/silcske.c, silcd/protocol.c and
1764 lib/silcclient/protocol.c.
1766 * Implemented the packet sequence number to the MAC computation.
1767 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1768 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1769 lib/silcclient/protocol.c.
1771 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Allow backup router to announce servers. All servers
1774 announced by backup router are added to the global list
1775 automatically. Update hte server's socket to our primary
1776 router also when backup router announces a server.
1777 Affected file silcd/packet_receive.c.
1779 * Do not update the client->router in the function
1780 silc_server_udpate_clients_by_server if the client is on
1781 global list. We might fail to find any specific server
1782 for locally connected clients and local cell clients. They
1783 should still use the `from' and not `to' as client->router.
1784 This fixes backup router resuming protocol. Affected file
1785 silcd/server_util.c.
1787 * Decrease channel statistics count only if the channel
1788 deletion worked. Affected files are silcd/server.c and
1789 silcd/server_util.c.
1791 * Added silc_server_update_servers_by_server to update origin
1792 of all server entries. Used during backup router protocol.
1793 Affected files silcd/server_util.[ch], silcd/server.c. and
1794 silcd/backup_router.c.
1796 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1797 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1798 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1799 lib/silccrypt/silchmac.c.
1801 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1803 * Assure that router cannot reroute the same channel message
1804 to the sender. Affected file silcd/packet_receive.c.
1806 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Made better checks that the channel message is not sent
1809 to the router it came from. Affected file is
1810 silcd/packet_send.c. Fixed memory leak too.
1812 * Announce informations for incoming router connection, but
1813 only after checking if it is replaced by backup router.
1814 Affected file silcd/packet_receive.c.
1816 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Fixed the backup resuming protocol to work in multiple
1819 router environment. Affected file silcd/server_backup.c.
1821 * Route packet only to one router in the function
1822 silc_server_packet_send_to_channel. Affected file is
1823 silcd/packet_send.c.
1825 * Fixed silc_server_send_notify_dest to set the broadcast
1826 flag. Fixed the silc_server_send_notify_topic to actually
1827 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1828 Affected file silcd/packet_send.c.
1830 * Changed the SFTP Filesystem interface. Changed the
1831 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1832 the filesystem operation function. The SilcSFTPFilesystem
1833 is now a context that is allocated by all filesystem allocation
1834 functions and it already includes the operations structure
1835 and filesystem specific context. It is given as argument
1836 now to the silc_sftp_server_start. This made the interface
1837 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1838 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1840 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Changed the backup router adding and getting interfaces
1843 in the server. The router that will be replaced by the
1844 specified backup router is now sent as argument. Affected
1845 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1848 * Added silc_net_addr2bin_ne to return the binary form of
1849 the IP address in network byte order. Affected files
1850 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1852 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * Check for existing server ID in silc_server_new_server
1855 and in silc_server_connect_to_router_final and remove the
1856 old entry if it exists. Affected file silcd/packet_receive.c,
1859 * Send the channel message always to only one router, either
1860 in upstream or downstream. Affected file is
1861 silcd/packet_send.c.
1863 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Wrote the definition of the backup resuming protocol to the
1866 protocol specification.
1868 * Removed one redundant channel key generation from normal
1869 server during joining procedure. Removed one redundant
1870 channel key sending from server to router during joining
1871 procedure. Affected file silcd/command.c.
1873 * Made minor bugfixes to the backup router resuming protocol.
1874 Affected file silcd/server_backup.c, server.c.
1876 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Added --disable-asm configuration option. Affected files
1879 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1882 * Implemented the backup resuming protocol that is used to
1883 resume the primary router position in the cell after the
1884 primary router comes back online. Affected files
1885 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1886 and silcd/server_util.[ch].
1888 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Sleep two (2) seconds after sending QUIT command to server.
1891 Affected file lib/silcclient/command.c.
1893 * Assure that if outgoing data buffer is pending do not force
1894 send any data. Affected file silcd/packet_send.c.
1896 * Assure that if outgoing data buffer is pending do not force
1897 send any data. Affected file lib/silcclient/client.c.
1899 * Implemented the backup router support when the primary router
1900 goes down. The servers and routers can now use the backup
1901 router as new primary router without loosing connectivity.
1903 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1906 in the server to indicate disabled entry. All data read
1907 from the connection will be ignored and no data is sent
1908 for entry that is disabled. Affected files are
1909 silcd/idlist.h, silcd/server.c.
1911 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Created SFTP client and server test programs in the
1914 lib/silcsftp/tests directory.
1916 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Implemented memory filesystem (virtual filesystem) for
1919 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1922 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Implemented the SFTP (SSH File Transfer Protocol) to the
1925 lib/silcsftp. It includes SFTP client and SFTP server
1928 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1930 * Moved lib/silccore/silcprotocol.[ch] to the
1931 lib/silcutil library.
1933 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1934 take variable argument list pointer as argument. Affected
1935 file lib/silcutil/silcbuffmt.[ch].
1937 * Added silc_buffer_set function that is used to set data
1938 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1939 Affected file lib/silcutil/silcbuffer.h.
1941 * Changed various routines in the core library to use the new
1942 silc_buffer_set instead of allocating new buffer only for
1945 * Added 64-bit value formatting and unformatting support to the
1946 silc_buffer_[un]format routines. Affected file is
1947 lib/silcutil/silcbuffmt.[ch].
1949 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1950 to includes/bitmove.h.
1952 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Fixed channel user mode saving in client library. Affected
1955 file lib/silcclient/command[_reply].c.
1957 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Defined the file transfer to the SILC Protocol. Added
1960 new packet type SILC_PACKET_FTP and defined File Transfer
1961 Payload. The mandatory file transfer protocol is SFTP
1962 (SSH File Transfer Protocol). Affected file in addition
1963 of the internet draft is lib/silccore/silcpacket.h.
1965 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1966 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1967 is used as part of backup router protocol when the primary
1968 router of the cell is back online and wishes to resume
1969 the position as primary router.
1971 * Redefined the MAC generation keys in the protocol. The
1972 same key is not used anymore in both direction. Both
1973 direction will now use different keys for sending and
1974 receiving. This fixes a potential security flaw. This
1975 change causes incompatibilities in the protocol.
1977 * Redefined also the MAC computation from the packet.
1978 An packet sequence number is now added to the MAC
1979 computation. This prevents possible replay attacks against
1980 the protocol. This change too causes incompatibilities
1983 Added `sequence' field to the SilcPacketContext to hold
1984 the current sequence number for the packet.
1986 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Added `created' field to the SilcIDListData in the file
1989 silcd/idlist.h to indicate the time when the entry was
1992 * Added `created' field to the SilcChannelEntry too. Affected
1993 file silcd/idlist.h.
1995 * Added `creation_time' aguments to all the announcement functions
1996 in the server. If it is provided then only the entries that
1997 was created after the provided time frame are actually
1998 announced. Affected file silcd/server.[ch].
2000 * The protocol says that the Channel ID's IP address must be
2001 based on the router's IP address. Added check for this in
2002 the silc_server_new_channel when processing incoming New Channel
2003 Payload. Affected file silcd/packet_receive.c.
2005 * Print out the correct version with --version in SILC client.
2006 Affected file irssi/src/silc/core/silc-core.c.
2008 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Fixed WHOWAS command to check for completnes of the client
2011 entry always, not just when the command is coming from client.
2012 Affected file silcd/command.c.
2014 * Added new function silc_server_packet_queue_purge to purge the
2015 outgoing data queue to the network. After the function returns
2016 it is guaranteed that the outgoing packet queue is empty.
2017 Affected file silcd/packet_send.[ch].
2019 * Purge the outgoing packet queue in the rekey protocol's final
2020 callback to assure that all rekey packets go to the network
2021 before quitting the protocol. Affected file silcd/server.c.
2023 * Added silc_client_packet_queue_parse as similar function as
2024 in server to the client library. The affected file is
2025 lib/silcclient/client.c.
2027 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Splitted silcd/server.c and created silcd/server_util.[ch]
2030 for utility functions.
2032 * Added new socket flag SILC_SF_DISABLED to indicate that the
2033 connection is open but nothing can be sent to or received from
2034 the connection. Affected file lib/silcutil/silsockconn.[ch].
2035 The checking for disabled socket is checked in the low level
2036 silc_socket_write and silc_socket_read functions.
2038 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Allow only nicknames and channel names that fits into the
2041 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2043 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * When processing JOIN command reply in server check that if
2046 the channel exists in our global list we'll move it the local
2047 list. Affected file silcd/command_reply.c.
2049 * Fixed the check whether client is joined on the channel already
2050 in JOIN command. Affected file lib/silcclient/command.c.
2052 * Fixed the JOIN command reply to check whether the channel
2053 already exists. Affected file lib/silcclient/command_reply.c.
2055 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Added silc_ske_status_string to map the SKE error numbers
2058 to readable strings. The affected files are
2059 lib/silcske/silcske[_status].[ch].
2061 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2063 * Do not show the private channels on the WHOIS channel list
2064 as it is not allowed by the protocol. The affected file is
2067 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Assure that the packet length digged from the actual packet
2070 is something sensible in the silc_packet_decrypt_rest_special
2071 in lib/silccrypt/silcpacket.c.
2073 * Free and NULL the allocated pointer in silc_hmac_alloc if
2074 the HMAC allocation fails. The affected file is
2075 lib/silccrypt/silchmac.c.
2077 * Print the selected security properties to the log files in
2078 the server. Affected file silcd/protocol.c.
2080 * Add SKE's reference counter even if calling the completion
2081 callback manually. Otherwise it goes negative, although it
2082 does not cause any problems. The affected file is
2083 lib/silcske/silcske.c.
2085 * Remove the client entry with short timeout after giving the
2086 KILL command. Affected file lib/silcclient/command.c.
2088 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2089 case all found clients are already disconnected (WHOWAS would
2090 found them) in the server. Affected file silcd/command.c.
2092 * Update the last_receive (time of last data received) to be
2093 updated only when received private or channel message so that
2094 the idle time showed in WHOIS makes more sense.
2096 * Added boolean field `valid' in to the SilcClientEntry in the
2097 client library to indicate whether the entry is valid or not.
2098 This fixes the nickname change bug on channel when changing
2099 the nickname to be same than the old (like nick to Nick) the
2100 nickname formatter doesn't set the new nick anymore to Nick@host.
2101 Affected file lib/silcclient/idlist.[ch].
2103 * Now actually fixed the nickname changing on disconnection.
2104 Added new function silc_change_nick to the Irssi SILC Client.
2105 Affected file irssi/src/silc/core/client_ops.c,
2106 irssi/src/silc/core/silc-nicklist.[ch].
2108 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Check that the public key exists in the GETKEY command before
2111 trying to encode it. Affected file silcd/command.c.
2113 * Print some notifications on received public keys with GETKEY
2114 command in the Irssi SILC Client. Affected files are
2115 irssi/src/fe-common/silc/module-formats.[ch],
2116 irssi/src/silc/core/client_ops.c.
2118 * Use IDENTIFY command to resolve the server information in the
2119 GETKEY command instead of INFO command. Affected file
2120 lib/silcclient/command.c.
2122 * All command reply functions in the client library now calls
2123 the pending command reply callbacks even if an error has
2124 occurred. The server has done this a long time and now it was
2125 time to move the client library to this as well. Now all
2126 errors can be delivered back to the pending command reply
2127 callbacks if necessary. Affected files are
2128 lib/silcclient/command[_reply].[ch].
2130 * Change the nickname on disconnection back to the username
2131 because in reconnect the server will enforce it to it anyway.
2132 Affected file irssi/src/silc/core/silc-servers.c.
2134 * Fixed a config file parsing bug in the Irssi SILC client.
2135 Affected file irssi/src/silc/core/clientconfig.c.
2137 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * When printing the channel mode on JOIN, verify that the
2140 channel key and channel's HMAC are valid. Affected file
2141 irssi/src/silc/core/client_ops.c.
2143 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2146 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2147 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2149 * Removed channel key rekey task deleting from the function
2150 silc_server_save_channel_key. Affected file silcd/server.c.
2151 Added explicit timeout task context instead that is used to
2152 delete the task if we are registering a new task before the
2153 new task has elapsed.
2155 * When channel key rekey occurs the client library now saves
2156 the old channel key for a short period of time (10 seconds) and
2157 is able to use it in case some is still sending channel
2158 messages encrypted with the old key after the rekey. Affected
2159 file lib/silcclient/[idlist.h|client_channel.c].
2161 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Added check to the silc_server_new_id_real to not accept
2164 new ID if it is the sender's own ID. Affected file is
2165 silcd/packet_receive.c.
2167 * Assure that we do not announce ourself or the one we've
2168 sending our announcements when we're router and are announcing
2169 servers to our primary router. Affected file silcd/server.c.
2171 * Fixed silc_server_command_identify_check_client to assemble
2172 correct WHOIS packet. It send corrupted WHOIS packet and
2173 caused problem with router to router connections. Affected
2174 file silcd/command.c.
2176 Fixed also silc_server_command_whois_check the same way
2177 as for the IDENTIFY command.
2179 * Added new SilcIDListStatus to the server in the SilcIDListData
2180 structure. The status now includes the current status of
2181 the entry (like registered, resolved etc.). Affected file
2182 silcd/idlist.[ch]. Defined a bunch of different status types
2183 as well. This replaced the old boolean registered field as well.
2185 Added resolve_cmd_ident field to the SilcClientEntry structure
2186 too so that if the entry is for example being resolved so
2187 another command may attach to the same pending command reply
2188 without requiring to resolve the same entry again. This concept
2189 should optimize the WHOIS and the IDENTIFY resolving under
2190 heavy load by taking away unnecessary resolving for entries
2191 that are being resolved already.
2193 Added support for adding multiple pending commands for one
2194 command idenfier. Affected file silcd/command[_reply].[ch].
2196 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2197 before deleting the data. Otherwise the hash table will have
2198 freed data in comparison functions. Affected file is
2199 silcd/command_reply.c.
2201 * Fixed silc_idlist_replace_client_id to add the new entry to
2202 the cache with NULL nickname. Otherwise there will be invalid
2203 memory as the nickname after the nickname is freed. Affected
2204 file silcd/packet_receive.c.
2206 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2207 saved into wrong slots because the previous number of entries
2208 was not taken into account. Affected file silcd/idlist.c.
2209 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2211 * If we are router and we receive JOIN notify to a channel that
2212 does not have any users then notified client is marked as the
2213 channel founder, as it is it. The affected file is
2214 silcd/packet_receive.c
2216 * Added to the extended hash table API's table_del_*ext functions
2217 the destructor as argument too, so that the caller can decide
2218 which destructor to use or whether to use destructor at all.
2219 Affected file lib/silcutil/silchashtable.[ch].
2221 * Fixed ID Cache purging. It actually deleted the entries from
2222 the hash table after the data was freed. The hash table ended
2223 up comparing freed memory. The affected file is
2224 lib/silccore/silcidcache.c.
2226 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Fixed Irssi SILC client's KILL command's HELP syntax.
2230 * The USERS command now resolves the detailed user information
2231 if the userinfo field is missing. Affected file is
2232 lib/silcclient/command_reply.c.
2234 * Do not print error in silc_file_read if the read file does
2235 not exist. Just silently return NULL. Affected file is
2236 lib/silcutil/silcutil.c.
2238 * Fixed the silc_log_output to not wine about NULL filename
2239 and to not create some bogus " " filename. Affected file is
2240 lib/silcutil/silclog.c.
2242 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Fixed various printing bugs on the user interface in the
2245 Irssi SILC Client. Minor changes that were forgotten from
2248 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Fixed the configure.in.pre and the compilation and distribution
2251 environment to support the new autoconf 2.52. That version is
2252 now required to compile the CVS trunk.
2254 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2257 to generally parse user@fqdn format strings. Affected file
2258 lib/silcutil/silcutil.c.
2260 * Added nickname_format and nickname_force_format fields to the
2261 SilcClientParams structure. The first one defines the format
2262 for the nicknames that the library will enforce if the receives
2263 multiple same nicknames. The second one is boolean value and
2264 can be used to force the library to always enforce the format
2265 to the nicknames regardles whether there are multiple nicknames
2266 or not. This configurable formatting was employed to flexibly
2267 support accessing multiple nicknames from the user interface.
2268 The userinterface can now set the nicknames to what ever format
2269 they prefer. Affected file lib/silcclient/silcapi.h.
2271 Added function silc_client_nickname_format to the file
2272 lib/silcclient/idlist.c. It performs the nickname formatting.
2274 Added new field `hostname´ to the SilcClientEntry context.
2275 It holds the hostname of the client. Affected file is
2276 lib/silcclient/idlist.h.
2278 * Irssi SILC Client sets the nicknames in nick@hostn format.
2279 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2280 irssi/src/silc/core/silc-core.c.
2282 The WHOIS printing now also shows both the real nickname and
2283 the formatted nickname so that user knows how to access the
2284 user if there are multiple same nicknames cached. Affected
2285 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2286 printing formatting too to take the hostname now as a separate
2287 argument. The Affected file is
2288 irssi/src/fe-common/silc/modules-formats.[ch].
2290 * Changed the silc_client_get_clients_local to accept the formatted
2291 nickname as argument. It accepts the real nickname too but the
2292 formatted nickname can be used to find the true entry from
2293 multiple entries. Affected file lib/silcclient/silcapi.h and
2294 lib/silcclient/idlist.c.
2296 * Added nickname_format_parse field to the SilcClientParams.
2297 It is a callback function provided by the application to parse
2298 the nickname out of the formatted nickname string. The library
2299 calls it to get the nickname from the formatted string. Since
2300 the application generally knows better the format of the nickname
2301 string it parses it instead of the library, even though library
2302 encodes the formatted string. If the callback function is not
2303 provided then the library will use the string as is. The
2304 affected file is lib/silcclient/silcapi.h.
2306 * All the nickname strings passed to the client library in
2307 commands are now expected to be formatted nickname strings.
2308 If the command does not support the formatted nickname string
2309 it will assume that the sent string is the actual nickname.
2310 Affected file lib/silcclient/command.c.
2312 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Added public key authentication support to OPER and SILCOPER
2315 commands in the client library. Affected file is
2316 lib/silcclient/command.c.
2318 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Changed the get_auth_methdod client operation to be asynchronous.
2321 It can be async if the application resolves the authentication
2322 method from the server during the negotiation. Added new
2323 SilcGetAuthMeth completion callback that the application will
2324 call after resolving the authentication method.
2326 Added function silc_client_request_authentication_method that
2327 the application can use to resolve the authentication method
2328 from the server. Added also SilcConnectionAuthRequest callback
2329 that the library will call after the server has replied. The
2330 application can call this function if it does not know the
2331 current authentication method.
2333 Affected files are lib/silcclient/client.c and
2334 lib/silcclient/silcapi.h.
2336 * The Irssi SILC client now automatically resolves the authentication
2337 method incase any configuration information is not present (and
2338 currently there never is). The affected file is
2339 irssi/src/silc/core/client_ops.c.
2341 * Fixed public key authentication from the client library.
2342 Affected file lib/silcclient/protocol.c. Changed also the
2343 protocol specification about the public key authentication in
2344 the connection authentication protocol. The actual data to be
2345 signed is now computed with a hash function before signing.
2347 * Fixed the public key authentication from the server as well.
2348 Affected file silcd/protocol.c.
2350 * Removed the mlock()'s from the memory allocation routines.
2351 Affected file lib/silcutil/silcmemory.c. The ./configure does
2352 not check anymore for the mlock(). Affected file is
2355 * Fixed USERS command in server to allow the execution of the
2356 command for private and secret channels if the client sending
2357 the command is on the channel. Affected file silcd/command.c.
2359 * Fixed silc_client_get_clients_local to return the clients
2360 count correctly. It could return wrong value. Affected file
2361 lib/silcclient/idlist.c.
2363 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2366 types. The assembler optimizations seemed not to like 64-bit
2367 data types. The assmebler optimizations thus are now enabled
2368 also for BSD systems as opposed to only enable them for Linux.
2370 * Do not check for threads at all on BSD systems. Affected
2371 file configure.in.pre.
2373 * Removed -n and -h options from the Irssi SILC Client since
2374 they are not used in silc.
2376 * Fixed the prime generation to assure that the first digit
2377 of the generated random number is not zero since our conversion
2378 routines does not like number strings that starts with zero
2379 digit. If zero digit is seen the random number is regenerated.
2380 This caused some corrupted RSA keys when the zero first digit
2381 was met. Affected file lib/silcmath/silcprimegen.c.
2383 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Fixed WIN32 configuration in the ./configure script.
2386 Fixed to include xti.h on environments that has it.
2387 Patches by Carsten Ilchmann and andrew.
2389 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Changed the silc_id_create_client_id to be collision
2392 resistant. It is now assured that there cannot be created
2393 two same client ID's. I suspect that some weird bugs in
2394 the server were actually caused by duplicate Client IDs.
2395 Affected file silcd/serverid.[ch]. A router receiving
2396 new ID now also assures and informs the sending server
2397 if the ID caused collision.
2399 * Changed the silc_id_create_channel_id to also assure that
2400 there are no collisions.
2402 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Statement about ignoring the Mutual Authentication flag when
2405 performing rekey with PFS was a bit misleading. It is ignored
2406 if it was set in the initial negotiation, it cannot be even
2407 set in the rekey. Fixed in the ke-auth draft. Started the
2408 new versions of the protocol drafts in the doc/.
2410 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Fixed a bug in silc_client_command_identify_save when saving
2413 new channel information. The channel name was no duplicated
2414 and caused crash on exit. Affected file is
2415 lib/silcclient/command_reply.c.
2417 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Fixed the getkey command handling in the server. Send just
2420 empty OK reply to the sender if the key could not be fetched
2421 (but everything else was ok, like the key just was not available).
2422 Changed the public key parameter to optional in the protocol
2423 specs so that empty OK reply can be sent. Affected file
2426 Added a message to Irssi SILC client to tell to user if the
2427 server did not return a public key.
2429 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Fixed a channel key regeneration bug. It registered new
2432 timeout tasks exponentially until all system resources were
2433 used. Affected file silcd/server.c.
2435 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Added the SILC Document generator to the scripts/silcdoc.
2438 It can be used to generate the Toolkit Reference Manual out
2439 of the source tree. Internally it will also use the RoboDoc
2440 generator now imported in util/robodoc.
2442 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2444 * Added couple of return's in rekey protocol if error orccurred
2445 during the protocol. The execution must be terminated.
2446 Affected file silcd/protocol.c. Also, terminate the protocol
2447 always with timeout.
2449 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * The client's Client ID was created initally from the wrong
2452 nickname (it could have been in format nick@host) in the
2453 silc_server_new_client. Affected file silcd/packet_receive.c
2455 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Added some SILC_LOG_ERROR's to various error conditions
2458 if client could not be added to ID cache. Affected files
2459 silcd/packet_receive.c and silcd/server.c.
2461 * When client's sock->user_data is freed, NULL also the
2462 client->router and client->connection pointers. Added check
2463 for these pointers being NULL to various places around the
2464 code. Affected file silcd/server.c.
2466 * Added client->data.registered == TRUE checks to various
2467 places around the code to assure that unregistered client's
2468 are not handled when it is not allowed. Affected file
2471 * Added `bool registered' fields to all
2472 silc_idlist_[server|client]_get_* routines to indicate whether
2473 the fetched client needs to be registered or not. Affected
2474 file silcd/idlist.[ch].
2476 * Add your own entry as registered to the ID cache in the
2477 server. Affected file server.c.
2479 * Fixed a bug in silc_server_new_server. The SilcServer was
2480 set as the new server's context instead of SilcServerEntry.
2481 This naturally caused some weird bugs.
2483 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Do not delete the channel rekey task when adding it
2486 for in silc_server_create_channel_key.
2488 * Changed the silc_server_create_channel_key to return
2489 TRUE or FALSE to indicate the success of the channel key
2492 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2494 * Fixed MSVC++ project files and added missing files to
2495 Makefiles under win32/.
2497 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Do not add TCP_NODELAY flag if the operating system
2500 does not have it defined. Affected files are
2501 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2503 * Fixed buffer overflow from Irssi SILC Client. Affected
2504 file irssi/src/fe-common/core/themes.c.
2506 * Fixed double free in client library in the file
2507 lib/silcclient/client.c when disconnecting from server.
2509 * Applied double free patch from cras to Irssi SILC client.
2510 Affected files irssi/src/core/[modules/expandos].c
2512 * Fixed the disconnection handling to Irssi SILC Client.
2513 The application must call silc_client_close_connection
2514 in ops->connect client operation in case of failure of
2515 the connection. Affected file is
2516 irssi/src/silc/core/client_ops.c.
2518 * Do not set sock->protocol to NULL in the function
2519 silc_client_close_connection after executing the protocol's
2520 final callback since the sock might not be valid anymore.
2521 Affected file lib/silcclient/client.c.
2523 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Do not enable SILC_THREADS if the linking with libpthread
2526 did not happen. Affected file configure.in.pre.
2528 * Added notion to protocol specification that server must
2529 verify the sent authentication payload with CMODE when
2530 setting the channel founder key. Implemented it to the
2531 server. Affected file silcd/command.c.
2533 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Added _EXTRA_DIST SILC distribution variable to the
2536 distributions file. It is used to conditionally add extra
2537 files or directories to the specific distribution. Affected
2538 files ./prepare, Makefile.am.pre and distributions.
2540 Removed the `_' from the start of the distribution names.
2543 * Added README.WIN32 for instructions to compile the Toolkit
2546 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Fixed a double free in disconnection in the server. Affected
2549 file is silcd/server.c.
2551 * Fixed the lib/silcske/groups.c to work now also with GMP
2552 MP library. The string conversion did not work when using
2553 specific base and the base is indicated in the string as well.
2555 * Created win32/ directory which now includes MSVC++ specific
2556 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2557 It will appear only in the toolkit distribution
2559 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Changed the key material distribution function in case when
2562 the hash output is too short. The data is now concatenated
2563 a bit differently than it used to. Made the change to the
2564 SKE protocol specification.
2566 * Added better GMP detection to configure.in.pre. A patch
2569 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Fixed a minor bug in SKE that might cause some problem on
2572 some platforms. Affected file lib/silcske/silcske.c.
2574 * Added the cookie checking for initiator in the SKE. It checks
2575 that the responder returns the sent cookie unmodified. The
2576 affected file is lib/silcske/silcske.c. Added new SKE
2577 error type INVALID_COOKIE that can be sent during the
2578 negotiation. Fixed some memory leaks as well.
2580 * Added the "invalid cookie" error message to Irssi SILC client's
2583 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Added `task_max' field to the SilcClientParams to indicate
2586 the maximum tasks the scheduler can handle. If set to zero,
2587 default values are used. Affected file lib/silcclient/silcapi.h.
2589 * Fixed memory leaks in silc_client_close_connection. Affected
2590 file lib/silcclient/client.c.
2592 * Added silc_client_del_client_entry to client library to free
2593 all memory of given client entry. Affected file is
2594 lib/silcclient/idlist.[ch].
2596 * Added new functions silc_client_del_channel and
2597 silc_client_del_server to delete channel and server entries.
2598 Affected file lib/silcclient/[silcapi.h/idlist.c].
2600 * Removed silc_client_del_client_by_id from silcapi.h.
2602 * Fixed the INFO command to return the server's own info
2603 correctly when querying by Server ID. Affected file is
2606 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Removed the non-blocking settings in WIN32 code in the
2609 silc_sock_[read/write] and added SleepEx instead. Affected
2610 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2611 of input data is now checked with FIONREAD and ioctlsocket.
2613 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Call silc_schedule_task_del_by_context in the
2616 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2617 Affected file lib/silccore/silcprotocol.c.
2619 * Call silc_protocol_cancel for active protocols in the
2620 silc_server_close_connection if the funtion
2621 silc_server_free_sock_user_data has not been called.
2622 Affected file silcd/server.c.
2624 * Generic tasks cannot be deleted using the del_by_fd
2625 task deleting function since generic tasks does not match
2626 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2628 * Added a notion to SILCOPER help file that the SILCOPER works
2629 only on router server, not on normal server.
2631 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Added for WIN32 support for the new scheduler as well.
2634 Affected file lib/silcutil/win32/silcwin32schedule.c.
2636 * Fixed the SHA1 implementation to work on various platforms.
2638 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2641 API. It is part of the scheduler now. Everything else is
2642 as previously but some functions has changed their names.
2643 Checkout the lib/silcutil/silcschedule.h for the interface.
2644 Updated all applications to use the new interface. Affected
2645 files are lib/silcutil/silcschedule.[ch].
2647 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2649 * Found a bug in the SKE implementation. The HASH value,
2650 specified by the protocol, was not computed correctly. The
2651 public key of the responder was not added to the computation
2652 even though it is mandatory. Affected file lib/silcske/silcske.c.
2653 This unfortunately causes incompatibilities with older
2654 clients and servers.
2656 * Added WIN32 specific network init and uninit functions:
2657 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2658 the Winsock2. Affected file lib/silcutil/silcnet.h and
2659 lib/silcutil/win32/silcwin32net.c.
2661 * Set the socket always to nonblocking mode on WIN32 after
2662 reading data or writing data. Affected file is
2663 lib/silcutil/win32/silcwin32sockconn.c.
2665 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Fixed various compilation problems under WIN32. Affected
2668 files lib/silcutil/win32/silcwin32thread.c and
2669 lib/silcutil/win32/silcwin32schedule.c.
2671 * Removed all _internal.h #includes from public header
2672 files. Internal headers must never be included from
2675 Removed also the lib/silcske/payload_internal.h file.
2677 * All include files that may be needed (public and some others
2678 included by the public headers) by application developers are
2679 now copied to the ./includes directory. It does not copy any
2680 internal headers. Affected file Makefile.defines.pre and all
2681 Makefile.am's under lib/ and subdirs.
2683 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Do not change the ~/.silc directory's permissions automatically.
2686 Affected file irssi/src/silc/core/clientutil.c.
2688 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Do not cancel the protocol in silc_server_close_connection
2691 it might cause recursion. Now cancelled in the function
2692 silc_server_free_sock_user_data. Affected file silcd/server.c.
2694 * Fixed the silc_server_remove_clients_by_server to regenerate
2695 the channel keys correctly finally. Added also new function
2696 silc_server_remove_clients_channels to actually do it.
2697 Affected file silcd/server.c.
2699 * Fixed the silc_server_new_channel to not crash by giving
2700 wrong router to the new channel. Affected file is
2701 silcd/packet_receive.c.
2703 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2705 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2706 which is given as argument to the silc_client_alloc now.
2707 It can be used to configure the client and set various parameters
2708 that affect the function of the client.
2710 * The USERS command in server did not check whether the channel
2711 is private or secret. Affected file silcd/command.c.
2713 * Added new argument to the USERS command in protocol specification.
2714 The USERS command now can take the channel name as argument
2715 as well. Added support for this in client and server and
2716 updated the protocol specs.
2718 * Completed the GETKEY command in client. It can be now used
2719 to fetch also servers public key not only some clients.
2720 Affected files lib/silcclient/command[_reply].c.
2722 * Added silc_client_get_server to return server entry by the
2723 server name. Affected files lib/silcclient/silcapi.h and
2726 * Redefined the IDENTIFY command in protocol specification to be
2727 more generic. It now can be used to query information about
2728 any entity in the SILC Network, including clients, servers and
2729 channels. The query may be based either the entity's name
2730 or the ID. Added support for this in both client and server.
2732 Affected files silcd/command.c and lib/silcclient/command.c
2733 and command_reply.c.
2735 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2736 the _from_client and _from_server functions. Affected file
2739 * Added silc_client_get_channel_by_id_resolve to the file
2740 lib/silcclient/silcapi.h to resolve channel information by
2741 its ID. Added also silc_client_get_channel_by_id that
2742 does not resolve it from the server.
2744 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Added SilcServerEntry context into the client library
2747 to represent one server. The INFO command now allocates
2748 these to save the resolved server info. For now on the
2749 client library will also keep information about servers,
2750 connected and resolved with INFO.
2752 The INFO command now allocates the SilcServerEntry context
2753 and saves the server info there. The COMMAND_REPLY in
2754 the INFO now returns the parameters to application in
2755 same order as defined in the protocol specification.
2757 The entries are cached in the client->server_cache.
2759 * The INFO command is now issued after received the Client ID
2760 from the server. Affected file lib/silcclient/client.c.
2762 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2763 to the application as the mode changer might be server.
2764 It is guaranteed that NULL is not returned anymore to the
2765 application. Affected file lib/silcclient/client_notify.c.
2767 The ID Type is now also passed to the application so that
2768 it can check whether the returned entry is SilcClientEntry
2771 Added new function silc_client_get_server_by_id to return
2772 the server entry by ID. Affected files are the
2773 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2775 * Do not create the channel in the Irssi SILC Client when issuing
2776 the JOIN command but when received the sucessful JOIN command
2777 reply. Otherwise the channel might get created even though we
2778 could not join it. The Affected file is
2779 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2781 * Fixed a channel joining bug in router. The router must also
2782 check the channel modes, invite and ban lists etc. when serving
2783 the JOIN command sent by normal server. Affected file is
2784 silcd/command.c. The router now resolves the client's
2785 information from the server who sent the JOIN command if it
2786 does not know it, and processes the JOIN command only after
2789 * Changed the SilcCommandCb to take new argument; void *context2.
2790 Affected file lib/silccore/silccommand.h
2792 The second argument in the command callbacks in the server now
2793 includes the SilcServerCommandReplyContext if the command was
2794 called as pending command callback from the command reply.
2795 Otherwise it is NULL. When called as pending the status of the
2796 command reply will be checked and if it was erronous the
2797 error will be sent to the original sender of the command.
2798 This way the client always receives the error messages even
2799 though the server was actually the one who received the error
2800 when it resent the command to router, for example. Affected
2801 files silcd/command[_reply].[ch].
2803 * Fixed sending WHOWAS command's error message to client if
2804 the requested client could not be found. It was missing.
2807 * Changed the CMODE and CUMODE commands reply arguments in the
2808 protocol specification. The Channel ID is now sent in both
2809 of the commands to identify the channel. Implemented this
2810 new feature to the client and server. Affected files
2811 lib/silcclient/command_reply.c and silcd/command.c.
2813 * Made better checks for invite and ban lists in the JOIN
2814 command in server. Affected file silcd/command.c.
2816 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2818 * The server now performs the incoming host IP/DNS lookup
2819 using the silc_socket_host_lookup and thus does not block
2820 the server anymore. Affected file silcd/server.c.
2822 * Completed the multi-thread support for SILC Scheduler in
2823 the lib/silcutil/silcschedule.c.
2825 * Fixed the configure.in.pre to detect the pthread correctly
2828 * Fixed a deadlock in silc_task_queue_wakeup in the file
2829 lib/silcutil/silctask.c.
2831 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Added new function silc_schedule_wakeup that is used in
2834 multi-threaded environment to wakeup the main thread's
2835 schduler. It needs to be used when a thread adds a new task
2836 or removes a task from task queues. After waking up, the
2837 scheduler will detect the task queue changes. If threads
2838 support is not compiled in this function has no effect.
2839 Implemented the wakeup mechanism to both Unix and WIN32
2840 systems. Affected files are lib/silcutil/silcschedule.[ch],
2841 lib/silcutil/unix/silcunixschedule.c and the
2842 lib/silcutil/win32/silcwin32schedule.c.
2844 * Added new function silc_task_queue_wakeup to wakeup the
2845 scheduler by the specified task queue. Affected file
2846 lib/silcutil/silctask.[ch].
2848 * The silc_socket_host_lookup_start now wakes up the scheduler
2849 after adding the timeout task. Affected file is
2850 lib/silcutil/silcsockconn.c.
2852 * The silc_socket_host_lookup is synchronous now if the threads
2853 support is not compiled in. However, the callback is still
2854 called asyncronously through the scheduler, anyway. Affected
2855 file lib/silcutil/silcsockconn.c.
2857 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2859 * Added new function silc_socket_host_lookup to perform
2860 asynchronous IP and FQDN lookups for the socket connection.
2861 Affected files lib/silcutil/silcsockconn.[ch].
2863 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2866 that may or may not compile the mutex support in.
2868 Changed the silc_mutex_alloc interface. It allocates the
2869 mutex now to the sent pointer and returns TRUE or FALSE.
2871 Affected file lib/silcutil/silcmutex.h.
2873 * Wrote the SILC Task Queue interface to support multi-threads.
2874 Affected file lib/silcutil/silctask.[ch].
2876 * Wrote the SILC Scheduler to support multi-threads. Affected
2877 file lib/silcutil/silcschedule.c.
2879 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2882 in lib/silcutil/win32/.
2884 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * Defined SILC Mutex API and SILC Thread API and implemented
2887 them for Unix. Affected files are
2888 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2889 lib/silcutil/unix/silcunixmutex.c and
2890 lib/silcutil/unix/silcunixthread.c.
2892 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * Fixed the silc_server_remove_clients_by_server's channel
2895 key re-generation. The hash table handling was incorrect
2896 and would not work with many channels. Affected file is
2899 * Fixed some memory leaks around the server code.
2901 * Rewrote the silc_server_get_users_on_channel to support IPv6
2902 based Client ID's. Affected file silcd/server.c.
2904 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2905 specification. However, a separate document must be written
2906 to define the detailed signing procedure and the payload
2907 associated with the flag. Defined the flag to the
2908 lib/silccore/silcchannel.h as well.
2910 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2912 * Changed the dynamic tables to static size tables in the
2913 lib/silccrypt/silchmac.c.
2915 * Removed GCC dependencies from the code. A patch by cras.
2917 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Do not show the error "Error receiving packet bla bla"
2920 in server if it really was not an error (-2 means that reading
2921 is pending). Affected file silcd/server.c.
2923 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Fixed a possible crash in silc_server_remove_clients_by_server
2926 in silcd/server.c. Fixed there also some memory leaks.
2928 * Fixed the silc_idlist_replace_client_id. It could replace
2929 wrong key in the hash table. Affected file silcd/idlist.c.
2931 * Do not check whether there are global users on the channel
2932 if the channel->global_users is FALSE. Affected functions
2933 silc_server_remove_from_one_channel and
2934 silc_server_remove_from_channels in silcd/server.c. Also,
2935 do not check if the removed client is local as we can be
2936 sure that global client was not removed from the channel
2937 and checking for global users is not needed.
2939 * The silc_server_remove_clients_by_server now re-generates
2940 the channel keys correctly for those channels that had
2941 clients removed from them. Affected file silcd/server.c.
2943 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Found the reason of random crashes in the server. We weren't
2946 ignoring the SIGPIPE signal (which can be sent in write())
2947 and it crashed the server. Affected file silcd/silcd.c.
2949 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Assure that sock->user_data is not NULL in the function
2952 silc_server_packet_send in silcd/packet_send.c.
2954 * Disconnect the remote connection if it could not be added
2955 to any ID lists in the server. The affected file is
2958 * Check in silc_server_packet_send[_real/dest] that the
2959 socket is not disconnecting and ignore the data if it is.
2960 Affected file silcd/packet_send.c.
2962 * Define inline to __inline on native WIN32 compilation.
2963 Affected file includes/silcwin32.h.
2965 * Added some explicit type casts for inline code since MSVC
2966 require them. Affected files lib/silcutil/silcbuffer.h,
2967 lib/trq/silcdlist.h and lib/trq/silclist.h.
2969 * Print warning in log files from now on if the packet
2970 decryption fails. Affected file silcd/server.c.
2972 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Changed the `say' client operation's interface to accept
2975 new `type' argument to indicate the type of the message sent
2976 by the library. The application may filter the library's
2977 messages according the type. The affected file is the
2978 lib/silcclient/silcapi.h.
2980 * Added two new functions to lib/silcclient/silcapi.h:
2981 silc_client_del_client and silc_client_del_client_by_id.
2982 Affected file lib/silcclient/idlist.c.
2984 * Moved the clientincludes.h from includes/ to silc/ and
2985 serverincludes.h from includes/ to silcd/.
2987 * The modes for the CMODE and CUMODE are now passed as
2988 uint32 for application with COMMAND_REPLY. The affected
2989 file is lib/silcclient/command_reply.c.
2991 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * /WHOIS without arguments shows client's own information.
2994 Affected file lib/silcclient/command.c.
2996 * Changed PING to not accept any arguments. The specs
2997 says that client can ping only the connected server so
2998 requiring an argument is not needed. Affected file is
2999 lib/silcclient/command.c.
3001 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * Fixed a fatal bug in private message sending and reception
3004 encryption and decryption when using private message keys.
3005 The implementation was incorrect and did not follow the
3006 specification. It causd that some of the message were
3007 lost since it did not use the sending and receiving keys
3008 as the protocol suggests. This has been fixed and will cause
3009 incompatibilities with older clients when sending private
3010 message encrypted with private message keys. Affected files
3011 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3012 and various other in Irssi SILC Client.
3014 Added `responder' boolean argument to the functions
3015 silc_client_add_private_message_key[_ske] to indicate when
3016 the key is added as responder or initiator of the key
3019 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Removed the silc_ske_check_version function and created
3022 a SilcSKECheckVersion callback. Added also a function
3023 silc_ske_set_callbacks that is now used to set all SKE
3024 callbacks. The callback functions are not given to
3025 the SKE functions anymore, but this function is used to
3028 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3030 * Added `silc_version' argument to the silc_client_alloc
3031 to define the version of the application for the library.
3032 The library will use the version string to compare it
3033 against the remote host's (usually a server) version
3034 string. Affected file lib/silcclient/silcapi.h
3036 * Added the KE protocol context to Key Agreement context
3037 in client library so that we can abort the SKE if it
3038 is in process when we get timeout. Affected file is
3039 lib/silcclient/client_keyagr.c.
3041 * Do not resolve the client ID forever if it returns in the
3042 first time that such client does not exist. This was done
3043 for example with private message. Affected file is
3044 lib/silcclient/client_prvmsg.c.
3046 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Do not add regex.h for WIN32. The affected file
3049 includes/silcincludes.h.
3051 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3052 not work yet 100%. It generates the DLL's automatically
3053 when compiling with --with-win32 under cygwin.
3055 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * lib/contrib/regex.c is not compiled on WIN32.
3059 * Added silc_net_get_socket_opt function to the
3060 lib/silcutil/silcnet.h.
3062 * Added includes/silcwin32.h for WIN32 specific includes
3065 * Do not use ptime structure or any of the posix process
3066 functions on WIN32 in lib/silccrypt/silrng.c.
3068 * Added silc_gettimeofday to provide generic function
3069 for struct timeval on all platforms. Added the function
3070 to lib/silcutil/silcutil.h.
3072 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3075 library as they clearly belong there. As a plus side we
3076 can make the actual socket connection routines platform
3079 Added also new generic function silc_socket_read and
3080 silc_socket_write (that used to be silc_packet_[read/write].
3081 The implementation of these are platform specific.
3083 * Added WIN32 specific routines of silc_socket_[read/write]
3084 to lib/silcutil/win32/silcwin32sockconn.c.
3086 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Added preliminary support for native WIN32 compilation under
3089 cygwin (using the -mno-cygwin option for GCC) to the
3090 ./configure.in.pre. The --with-win32 now prepares the
3091 compilation for native WIN32.
3093 * Rewrote the SILC Scheduler interface in the file
3094 lib/silcutil/silcschedule.h. The scheduler is now context
3095 based and does not have anymore any global static scheduler.
3096 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3097 and created lib/silcutil/win32 directory for WIN32 based
3100 * Added Unix specific network routines to the
3101 lib/silcutil/unix/silcunixnet.c and the old
3102 lib/silcutil/silcnet.c includes now only generic routines.
3104 Added WIN32 specific network routines to the
3105 lib/silcutil/win32/silcwin32net.c.
3107 * Added Unix specific utility functions from the
3108 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3110 * Added WIN32 SILC Scheduler to the file
3111 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3114 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Do not handle JOIN notify in the server if the target client
3117 is not registered (idata->registered == FALSE). The affected
3118 file is silcd/packet_receive.c.
3120 * Update the nickrec->founder in event_cumode in the Irssi SILC
3121 client. Affected file irssi/src/silc/core/silc-channels.c.
3123 * Fixed the CUMODE_CHANGE notify handling in the server when
3124 server and router are announcing their clients on channels.
3125 Now the mode changes are saved and notified correctly. The
3126 affected file is /silcd/packet_receive.c.
3128 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3129 They really did not replace the cache entry in the ID Cache.
3130 Now they do that. Affected file silcd/idlist.c.
3132 * Fixed the KICK notify handling in the Irssi SILC client to
3133 update the channel records so that the kicked client does not
3134 appear to be on the channel. The affected file is
3135 irssi/src/silc/core/silc-channels.c.
3137 * Always update the conn->current_channel when executing command
3138 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3140 * Fixed the KILL notify handling in Irssi SILC client to remove
3141 the killed client on all channels.
3143 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Fixed the silc_parse_command_line to remove extra spaces
3146 from the start and end of the arguments. Affected file is
3147 lib/silcutil/silcutil.c.
3149 * Cancel and free any active protocol in the function
3150 silc_server_close_connection. Affected file silcd/server.c.
3152 * Cancel and free any active protocol in the function
3153 silc_client_close_connction. Affected file is
3154 lib/silcclient/client.c.
3156 * Do not execute the KILL command for clients that are in
3157 history (ie. they are not in the network). Affected file is
3160 * Fixed KILL notify handling, client does not crash anymore.
3161 Affected file irssi/src/silc/core/silc-channels.c.
3163 * Reduced the default packet buffer size from 2048 to 1024 in
3164 lib/silccore/silcpacket.c.
3166 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3167 counter to the SKE context that is incresed when the SKE library
3168 performs async operation outside the library. If the outside
3169 process frees the SKE context and FREED status will be set
3170 and the library will detect after the sync operation that the
3171 libary is freed. The affected files are
3172 lib/silcske/silcske[_status].[ch].
3174 * Resolve the client entry information in the function
3175 silc_client_channel_message to assure that NULL pointer is not
3176 passed as client entry to the application. */
3178 * Fixed the task timeout calculation to assure that there is
3179 never negative timeouts. The affected file is
3180 lib/silcutil/silcschedule.c.
3182 * Fixed the channel user mode notification sending in server.
3183 It was sent point-to-point to the router (or to server by router)
3184 but it needs to be destined to a channel. The routines now
3185 supports sending the channel user mode notifys to the channels
3186 when announcing clients and channels. Affected files are
3187 silcd/server.c and silcd/packet_receive.c.
3189 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3190 It did not actually replace the old channel entry in the cache.
3191 Affected file lib/silcclient/client_notify.c.
3193 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Fixed a possible crash in silc_packet_send_prepare. It now
3196 assures always that there is enough space in the buffer and
3197 at the tail area of the buffer (for MAC).
3199 Fixed the inbound buffer reallocation in silc_packet_read.
3200 It was old code and did not handle the reallocation correctly.
3203 The affected file is lib/silccore/silcpacket.c.
3205 * Fixed buffer overflow in silc_parse_nickname in the file
3206 lib/silcutil/silcutil.c.
3208 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * make install generates new server keys only if there is not
3213 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3216 Added check that if the NOREPLY is set then we will not send
3217 the away message. This avoids infinite loop of away messages
3218 if both clients are away. The affected file is
3219 lib/silcclient/client_prvmsg.c.
3221 * Fixed client crash if /NICK was given without arguments.
3222 Affected file lib/silcclient/command.c.
3224 * Server does not send the invite list in INVITE command back
3225 to the client if the list was not altered. Added this notion
3226 to the protocol spec as well. Affected file silcd/command.c.
3228 Fixed possible crash in INVITE command by checking the
3229 value of silc_server_get_client_route command.
3231 * Fixed the INVITE notify type handling. The arguments are now
3232 taken in correct order and client does not crash. The affected
3233 file is irssi/src/silc/core/silc-channels.c.
3235 Removed the "Inviting xxx to channel" message from the
3236 client library away and let the application handle it.
3237 Affected file lib/silcclient/command.c. Added that message
3238 to Irssi SILC client's message formats.
3240 * Fixed CMODE command crash in client. It now checks the
3241 amount of arguments correctly and does not crash. The affected
3242 file is lib/silcclient/command.c.
3244 * Do not create new channel automatically in silc_channels_join
3245 but check whether the channel by that name already exists.
3246 Affected file irssi/silc/core/silc-channels.c.
3248 * Do not send the SERVER_SIGNOFF to router if the disconnected
3249 entity was the router. Affected file silcd/server.c.
3251 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3252 SILC client as it was missing from there.
3254 Added the handling of the KICK notify to the Irssi SILC client
3255 as it was missing. Added "you have been kicked" message to
3256 Irssi SILC client's message modules formats.
3258 Added the handing of the KILL notify to the Irssi SILC client
3259 as it was missing. Added the kill message module formats
3262 The affected file is irssi/src/silc/core/silc-channels.c.
3264 * The router did not save the channel mode the server announced.
3265 Affected file silcd/packet_receive.c.
3267 * Fixed a possible crash in INFO command in server. If the
3268 server did not provide the server info it crashed. Affected
3269 file silcd/command.c.
3271 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Fixed the GETKEY command in the server to check also the
3274 global list. Otherwise the GETKEY would not work correctly
3275 in normal SILC server. Affected file silcd/command.c.
3277 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Fixed GETKEY crash, it crashed if the command did not succseed.
3281 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3284 is now real and not just an macro interface to GMP.
3286 Removed the entire GMP from the source tree and imported new
3287 NSS MPI library instead. Reason for removing GMP is that it is
3288 extremely large and compiles extremely slow. The NSS MPI
3289 is only a few files and compiles in less than 10 seconds.
3290 The speed is also about the same as GMP. The MPI is imported
3291 to lib/silcmath/mpi.
3293 If the system has GMP installed we will still use the GMP.
3294 If it is not then the NSS MPI will be compiled.
3296 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Merged a long nickname (127 characters long) crash bugfix from
3299 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3301 * Merged a freed memory reference bugfix from Irssi CVS tree.
3302 Affected file irssi/src/core/commands.c.
3304 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added the server's public key sving and verification to the
3307 server when performing the SKE. This was missing and the
3308 remote server's (or router's) public key was accepted without
3309 checking whether we have it previously or trust it at all.
3310 Affected file silcd/protocol.c.
3312 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Check in the silc_server_timeout_remote if protocol is active
3315 and make sure that the protocol's final callback is called so
3316 that all memory if freed. Affected file silcd/server.c.
3318 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * silc_server_whois_send_reply crashed the server if the nickname
3321 was 127 characters long. Affected file silcd/command.c.
3323 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Added sanity check to the silc_server_new_client. If the hostname
3326 is provided inside username then check that the provided hostname
3327 really is the same as the resolved one. If the hostname was not
3328 resolved then check it from the public key. Affected file is
3329 silcd/packet_receive.c.
3331 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3332 if the server disconnected us and the connection is not valid
3333 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3335 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3336 the library to the lib/silcutil/silcutil.[ch].
3338 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Close log file after open. Affected file
3341 lib/silcutil/silclog.c.
3343 * Check whether sock == NULL in silc_client_send_packet and return
3344 if it is. Affected file lib/silcclient/silcclient.c.
3346 * Check rec->entry == NULL in the Irssi SILC Client before
3347 sending the channel message. Affecte file is
3348 irssi/src/silc/core/silc-servers.c.
3350 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Merged a splitted window bugfix from Irssi CVS tree. The
3353 affected file is irssi/src/fe-text/textbuffer-view.c.
3355 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3356 It did not print nickname.
3358 * Improved the distributions system a bit.
3360 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3363 irssi/src/fe-text/gui-window.c.
3365 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3366 to in-active server. The affected file is
3367 irssi/src/silc/core/client_ops.c.
3369 * Resolve the client in USERS command reply if the entry does
3370 not have username resolved. The affected file is
3371 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3372 command to WHOIS command to really resolve stuff. The USERS
3373 is not used any more in any critical section so WHOIS can
3374 be used even though it might be slower than IDENTIFY.
3376 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3379 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Changed the protocol API a bit more consistent in the
3382 lib/silccore/silcprotocol.[ch].
3384 * Changed the following headers to ROBODoc format:
3386 lib/silccore/silcpayload.h
3387 lib/silccore/silcprotocol.h
3388 lib/silccore/silcsockconn.h
3390 All core library headers are now formatted.
3392 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * Fixed a bug in Irssi SILC client; do not show that you are
3395 server/router operator if you really are not. Affected file is
3396 irssi/src/silc/core/client_ops.c.
3398 * Renamed silc_command_free_payload to silc_command_payload_free.
3399 Affected file lib/silccore/silccommand.h
3401 * Added silcmath.h to include the prototoypes of various routines
3402 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3405 * Changed the following headers to ROBODoc format:
3407 lib/silccore/silcchannel.h
3408 lib/silccore/silccommand.h
3409 lib/silccore/silcid.h
3410 lib/silccore/silcidcache.h
3411 lib/silccore/silcmode.h
3412 lib/silccore/silcnotify.h
3413 lib/silccore/silcpacket.h
3414 lib/silcmath/silcmath.h
3416 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Added checking to the server code not to start the server if
3419 ciphers and stuff are not configured properly. Affected files
3420 silcd/serverconfig.[h] and silcd/server.c.
3422 * Changed the layout of the header files of the public interfaces
3423 in the SILC libraries. The new layout supports ROBODoc
3424 documentation tool (and some others) so that it is easy to create
3425 a library reference manual. All the other headers and source
3426 code must still follow the CodingStyle document. Also source
3427 code must not include these ROBODoc stuffs, only the headers.
3428 Furthermore, all public interface headers must now be named
3429 by using `silc' prefix, example: silcapi.h, silccipher.h.
3430 Some files were renamed due to this. All the other headers
3431 must not be used as public interfaces. I will update the
3432 CodingStyle document later. Changed following headers, so far:
3434 lib/silcclient/silcapi.h
3435 lib/silccore/silcauth.h
3436 lib/silccore/silcprivate.h
3437 lib/silccrypt/silcdh.h
3439 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Removed silc_client_packet_send_flush from the client library
3444 as it is not needed. Affected file lib/silcclient/client.[ch].
3446 * Added printing of message of unresolved authentication method
3447 to the Irssi SILC client. Added it to the module formats.
3448 Removed the same message from the client library.
3450 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Added new distribution feature, DISTLABEL. Every distribution
3453 can define own preprocessor label that can be used in the
3454 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3455 file distributions, acconfig.h.pre and prepare.
3457 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Added Makefile.defines_int to include the actual definitions
3460 for Makefile.defines.in. Tested the new distribution system,
3461 created distributions and tested installation.
3463 * Added AWAY message printing to the Irssi SILC client. Added
3464 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3466 * Added SCONNECT command to call the SILC's CONNECT command.
3467 Cannot use CONNECT directly since Irssi uses that internally.
3468 Affected file irssi/src/silc/core/silc-servers.c.
3470 Added ACTION local command. It is same as ME command but takes
3471 the channel as mandatory argument.
3473 Rewrote some of the Irssi's help files to suite for SILC
3476 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Added Makefile.defines[.in] that should for now on be included
3479 in all Makefile.am file in the source tree. That file includes
3480 all common compilation definitions for SILC source tree.
3482 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Minor changes to the ./prepare script to change the package
3485 name according the distribution name to the configure.in.
3487 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Created new distribution system. Added file `distributions'
3490 that defines all the distributions that can be created out of
3491 the SILC source tree. The ./prepare script now reads that
3492 file to determine how to prepare the distributions. The
3493 first argument to the ./prepare is the name of the distribution
3494 and second is the version of the distribution. If given
3495 without arguments it creates the default (toolkit) distribution
3496 with the default version (defined in ./prepare).
3498 All Makefile.am files that are subject to the distributions
3499 are now named as Makefile.am.pre. These are ./Makefile.am
3500 and lib/Makefile.am. Others may be changed later.
3502 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Added invite list, ban list, some key management and connection
3505 error message printing to module formats in the Irssi SILC client.
3507 * Added new silc_client_set_away_message to set the away message
3508 that is back to the person who sent private message. The
3509 affected file lib/silcclient/silcapi.h and the
3510 lib/silcclient/client_prvmsg.c.
3512 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Fixed the private message sending in the Irssi SILC client,
3515 added local command KEY to the Irssi SILC client.
3517 Added key management and key agreement message formats to the
3518 irssi/src/fe-common/silc/module-formats.[ch].
3520 Added USERS (alias WHO) printing, server/router operator
3521 indication and LIST command printing to the module formats.
3523 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Fixed channel joining notify handling, cumode notify handling
3526 from Irssi SILC client.
3528 * Added SILC specific module-formats to the Irssi SILC client so
3529 that SILC specific message hilighting, colors etc is possible.
3530 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3532 Added channel mode, channel user mode, actions, notices,
3533 whois and whowas printing to the the module-formats.c.
3535 * Fixed a bug in channel deletion in the server. The channel
3536 is not left to the cache even if the channel founder auth mode
3537 is set when there are no users anymore on the channel. Affected
3538 file silcd/server.c.
3540 * The silc_net_localhost now resolves the entire hostname including
3541 the domain name. Affected file lib/silcutil/silcnet.c.
3543 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Changed the ask_passphrase client operation to be ascynchronous.
3546 It has now a completion callback and a context that the
3547 application must call after it has got the passphrase from
3548 the user. Affected files lib/silcclient/silcapi.h,
3549 lib/silcclient/protocol.c, lib/silcclient/command.c and
3552 Added SilcAskPassphrase callback that the application calls
3553 to deliver the passphrase to the library.
3555 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3556 The public key verification and especially a certificate
3557 verification is asynchronous procedure.
3559 Added new SILC_SKE_STATUS_PENDING status to indicate the
3560 request is pending and a callback will be called to finalize
3563 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3564 indicate that remote end did not send its public key (or
3565 certificate), even though we require it. Added check for this
3566 condition in the SKE. This was a security bug, now fixed.
3568 Defined new SilcSKEVerifyCbCompletion callback that is called
3569 when the verification process is completed.
3571 The affected files lib/silcske/silcske_status.h and
3572 lib/silcske/silcske.[ch].
3574 * Changed the verify_public_key client operation to be async
3575 as well. Defined SilcVerifyPublicKey callback that is used to
3576 indicate the success of the public key verification process.
3578 Changed the server and client to use the new async client
3581 * Changed the Irssi SILC client's internal scheduler to be called
3582 twice as many times as it used to be. As a result the client
3583 should be a bit faster now. Affected file is
3584 irssi/src/silc/core/silc-core.c.
3586 * Added support to Irssi SILC client of asynchronous public key
3587 verification and passphrase inquiry. Affected file is
3588 irssi/src/silc/core/silc-core.c.
3590 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Do not say "You have left channel %s" in client library.
3593 Moved it to the application. Affected files are
3594 lib/silcclient/command.c and silc/client_ops.c.
3596 * Fixed silc_client_get_clients. Command context was not
3597 duplicated and was freed memory in the callback. Affected
3598 file lib/silcclient/idlist.c.
3600 * Do not say "you are now talking..." on JOIN command in the
3601 client library. The appliation must handle it.
3603 * Do not say ".. changed topic to" in command reply in the
3604 client libary. The application must handle it.
3606 * Fixed TOPIC command sending in the client library.
3608 * Fixed a memory leak in silc_client_command_free in the file
3609 lib/silcclient/command.c.
3611 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Imported a modified version of Irssi client to the source tree.
3614 The Irssi will be used to create a new client called
3615 Irssi SILC. Imported to irssi/.
3617 Added silc_core_init_finish function to the Irssi. Affected
3618 file irssi/configure.in.
3620 A lot changes in the Makefile.ams around the irssi tree.
3622 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Do not rehash if the new size is same as the old size of the
3625 hash table, in the silc_hash_table_rehash*. The affected file
3626 lib/silcutil/silchashtable.c.
3628 * Replaced hash_table_del_by_context calls from the server
3629 (when channel->user_list and client->channels) to the
3630 hash_table_del as it is sufficient and faster.
3632 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Added silc_hash_table_list, silc_hash_table_get and the
3635 SilcHashTableList structure to provide an alternative way to
3636 traverse the hash table. The affected files are
3637 lib/silcutil/silchashtable.[ch].
3639 * Changed the server's idlist routines to use the hash table
3640 routines to optimize the code.
3642 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Replaced the client entry's `channel' list and channel entry's
3645 `user_list' list to hash tables for optimized lookup. Changed
3646 the code to use the hash table interface around the code.
3647 Affected file lib/silcd/idlist.[ch].
3649 * Added `auto_rehash' boolean argument to the function
3650 silc_hash_table_alloc to indicate whether the hash table should
3651 auto-rehash when it thinks is appropriate time. It will
3652 increase the hash table size if the there is twice as much
3653 entries in the table than the size of the table, and will
3654 decrease the size if there are twice as less entries than
3655 the size of the table.
3657 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3661 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * silc_idcache_purge_by_context deletes the entry now by context
3664 as it is supposed to do. Affected file lib/silccore/idcache.c.
3666 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3667 client is not anymore valid (WHOWAS givens the info) and not
3668 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3670 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Removed the `data' and `data_len' arguments from the ID Cache
3673 interfaces and added `name' argument. ID Cache does not handle
3674 anymore the binary data only a names associated with given ID.
3676 * When hashing a Client ID with silc_hash_id the entire ID is
3677 not hashed anymore, instead only the hash of the Client ID is
3678 hashed. This way we can access the Client ID from the cache
3679 with Client ID but with the hash of the ID (which is a hash of
3680 the nickname) as well without any difference in performance.
3682 Added also silc_idcache_find_by_id_one_ext to do one on one
3683 searching when we have the actual ID. Added also function
3684 silc_hash_client_id_compare. The affected files are
3685 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3687 * When hashing the name associated with a ID it is always done
3688 in lowercase. This way we can access the cache without worrying
3689 about case-sensitivity, even though, for example nicknames are
3692 * Fixed a bug in server with channel message sending. It put
3693 wrong ID type as destination ID. The affected file
3694 silcd/packet_send.c.
3696 * silc_idcache_del_by_context now deletes from all hash tables
3697 by context. Affected file lib/silccore/idcache.c.
3699 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Changed the client library to use the new ID Cache interface.
3702 Changes around the source tree.
3704 * Added silc_hash_table_rehash_ext to rehash with specific
3705 hash function. Affected file lib/silcutil/silchashtable.[ch].
3707 * Added silc_hash_string_compare to compare two strings in the
3708 hash table. Affected file lib/silcutil/silcutil.[ch].
3710 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Added new function silc_idcache_del_by_context into the
3713 lib/silccore/idcache.[ch].
3715 * Changed the server's ID list routines to use the new ID Cache
3716 interface. Changes around the source tree.
3718 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Added silc_hash_table_del[_by_context]_ext functions in to the
3721 lib/silcutil/silchashtable.[ch].
3723 Removed silc_hash_table_find_all* routines and added new
3724 silc_hash_table_find_foreach to replace them.
3726 Added silc_hash_table_replace_ext function as extended
3727 replacing function. Separated the simple hash table interface
3728 from the extended hash table interface in the file
3729 lib/silcutil/silchashtable.h.
3731 * Fixed minor bugs and changed it to use some of the new
3732 hash table functions in lib/silccore/idcache.c
3734 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Added new function silc_hash_table_find_all to return all keys
3737 in the hash table by the specified key. As the hash table is
3738 collision resistant it also makes it possible to have several
3739 duplicate keys in the hash table. This function may be used to
3740 find all of the keys from the hash.
3742 Added user_context arguments to the SilcHashFunction,
3743 SilcHashCompare and SilcHashDestructor to deliver user specified
3746 Added new fuctions silc_hash_table_find[_all]_ext to do
3747 extended lookup with specified hash and compare functions and
3748 specified user contexts.
3750 Added new function silc_hash_table_add_ext to add the key
3751 with specified hash function and user context.
3753 Added new function silc_hash_table_foreach to traverse all
3754 entrys in the hash table. Added SilcHashForeach callback
3757 Added new function silc_hash_table_del_by_context to delete
3758 the entry only if the context associated with the key matches.
3760 Affected files are lib/silcutil/silchashtable.[ch].
3762 * Removed silc_hash_[server/client/channel]_id and added just
3763 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3764 silc_hash_id_compare to compare two ID's using as the hash table
3765 comparison function. Added also silc_hash_data to hash
3766 binary data and silc_hash_data_compare to compare it.
3768 * Removed silc_idlist_find_client_by_hash as it is not needed
3769 anymore. Affected file silcd/idlist.[ch].
3771 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3772 to use internally the SilcHashTable. The new ID Cache is a lot
3773 faster than the old one. Some of the ID Cache interface was also
3774 rewritten and obsolete and stupid functions were removed.
3776 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Added entry_count field to the SilcHashTable to keep the number
3779 of the entries in the table. Implemented the function
3780 silc_hash_table_rehash. Added new function
3781 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3783 Fixed a minor bug in silc_hash_table_free.
3785 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3786 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3787 into the lib/silcutil/silcutil.[ch].
3789 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Implemented a collision resistant hash table into the
3792 lib/silcutil/silchashtable[ch]. See the header and the source
3793 for the SilcHashTable API.
3795 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Merged dotconf version 1.0.2 into lib/dotconf.
3799 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Do not compile anything in lib/silcsim/* if the SIM support
3802 is not enabled. The tree should now compile without problems
3805 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Compiled the SILC under cygwin. Compiled and tested briefly
3808 without problems. More tests needed. The SIMs didn't compile
3811 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3813 * Fixed possible crash in silc_get_username in the
3814 lib/silcutil/silcutil.c.
3816 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Fixed a va_arg in silc/client_ops.c.
3820 * Oops, RC5 routines were named AES and caused some problems
3821 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3823 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Added new SilcIDIP structure into the lib/silccore/id.h and
3826 replaced the old `ip' fields from all SILC ID's to that type.
3827 This is a step towards IPv6 support.
3829 The silc_id_get_len takes now the ID as an extra argument.
3830 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3831 both IPv4 and IPv6 based ID's.
3833 The affected files are lib/silccore/id.[ch] and other files
3834 around the tree using these routines.
3836 * Removed the ID length arguments in server from various
3837 silc_server_send_notify_* routines -> they are not needed
3840 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Fixed memory leak in silc_encode_pem_file in the file
3843 lib/silcutil/silcutil.c.
3845 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Check minor version as well in the SKE. Affected files are
3848 silcd/protocol.c and lib/silcclient/protocol.c.
3850 * Added --identifier option to the server so that an identifier
3851 can be when creating the public key for the server. Affected
3852 file is silcd/silcd.c.
3854 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3855 lib/silccrypt/silcpkcs.c.
3857 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Register default ciphers and stuff when using -C option with
3860 the server. Affected file sildc/silcd.c.
3862 * Put back the servers public key filename format, it is better
3863 than the new one. For now, the client keys are saved with the
3864 new filename format. The affected file silc/client_ops.c.
3866 * Implemented the Cipher API for the rest of the ciphers that
3867 did not implement it or implemented it the wrong way.
3869 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Register default ciphers and stuff when using the -S option
3872 in the client. Affected file silc/silc.c. Same also when
3873 creating new key pair with -C option.
3875 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Fixed the silc_verify_public_key client operation function to
3878 save the public keys differently. The fingerprint is now
3879 used as filename and not the hostname. This way also the
3880 client keys are saved uniquely and not with hostnames. The
3881 affected file is silc/client_ops.c.
3883 * Trimmed the silc_hash_fingerprint function to remove extra
3884 whitespaces from the end of the fingerprint. The affected
3885 file is lib/silccrypt/silchash.c.
3889 * Added silc_cipher_register_default function to register all
3890 default ciphers. It can be used when configuration files
3891 does not exist and the application does not want any specific
3892 ciphers in any specific order.
3894 The SilcDList is now used as silc_cipher_list dynamically
3895 allocated cipher list. Removed the static list all together
3896 and now all ciphers must be allocated to the dynamic list.
3897 The silc_cipher_alloc routine was changed to check only the
3900 All silc_cipher_* routines that used to return int returns
3903 The affected files lib/silccrypt/silccrypt.[ch].
3905 * The same thing was done to silc_hash_* as for silc_cipher_*
3906 routines. Affected files lib/silccrypt/silchash.[ch].
3908 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3909 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3910 Added also silc_pkcs_[un]register[_default] functions.
3911 Removed the data_context from the PKCS API.
3913 * Added silc_hmac_register_default function to register default
3914 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3915 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3916 to unregister all hmacs at once.
3918 * Register the default ciphers, hash functions, PKCSs and HMACs
3919 if client's configuration file does not exist. The affected
3922 * The client did not load the hash functions from the SIM
3923 modules at all. Added support for this. Affected file is
3924 silc/clientconfig.c.
3926 * When decoding public key with silc_pkcs_public_key_decode, check
3927 the supported algorithm only if PKCS are registered. Affected
3928 file lib/silccrypt/silcpkcs.c. The same was done with the
3929 silc_pkcs_private_key_decode.
3931 * Fixed the SILC List routines to keep the list always in order.
3932 It used to change the list's order when traversing the list but
3933 not it preserves the order. Affected file lib/trq/silclist.h.
3935 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Added the client library to use the SilcSocketConnection's
3938 reference counter (by silc_socket_dup) to prevent the bug that
3939 the socket object may be freed underneath async operation.
3941 * The name resolv library checking fixes in the configure.in.pre.
3944 * Created new version of the protocol drafts for future
3945 development. The -03 drafts are the ones that will be changed
3946 in the trunk now and the -02 will remain as they are.
3948 * Send list of CUMODE notifys to the router when announcing
3949 the channel users to the router. Affected file silcd/server.c.
3950 If the router receiving channel founder CUMODE for a channel
3951 that already has channel founder it will send CUMODE notify
3952 to the sender to remove the channel founder rights from the
3953 announced client. Affected file silcd/packet_receive.c.
3955 * The CUMODE notify may now use Server ID as well as the entity
3956 who changes the mode. Updated protocool specs.
3958 * Updated INSTALL and README files.
3960 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * New web pages in the http://silc.pspt.fi. The pages was
3967 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Implemented the [DenyConnectin] config section in the server.
3970 Added silc_server_config_denied_conn to check whether incoming
3971 connection is denied. Affected file silcd/serverconfig.[ch].
3973 * Do not check the ports when checking the incoming configuration
3974 data if the port is 0, meaning any. Affected file is
3975 silcd/serverconfig.c.
3977 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Fixed buffer overflow in silc_string_compare in the file
3980 lib/silcutil/silcutil.c.
3982 * Fixed double free in silc_server_command_leave in the file
3985 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Fixed the version checking in the server. Affected file is
3990 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Fixed the configuration data fetching when accepting new
3993 connections in the server. Affected file silcd/server.c.
3995 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added `sender_entry' argument to the function
3998 silc_server_packet_relay_to_channel so that we can check
3999 whether some destination actually belongs to the same route
4000 the sender belongs (ie, we must not resend the packet to the
4001 sender). Affected file silcd/packet_send.[ch].
4003 * Added `servername' field to the SilcClientEntry in the server
4004 to hold the name of the server where client is from. Affected
4005 file is silcd/idlist.h.
4007 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Moved the channel message encrypting in the router betwen
4010 router connections from silc_server_channel_message to the
4011 silc_server_packet_relay_to_channel since we want to check
4012 whether we have anybody channel before encrypting anything.
4013 Affected files silcd/packet_[receive/send].c.
4015 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Fixed the [AdminConnection] server config section to support
4018 multiple entries. Affected file silcd/serverconfig.c.
4020 * Added support into the server to check the validity of the
4021 incoming connection before executing any KE or authentication
4024 * The connection configuration is now saved to the KE and
4025 connection auth protocol contexts and not fetched anymore in
4026 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4028 * The local hosts listenning address and port is also resolved
4029 now when starting the server. We want to have the socket object
4030 to include the real address and port for the listener. Added
4031 new function silc_net_check_local_by_sock into the files
4032 lib/silcutil/silcnet.[ch].
4034 * Fixed a broadcast bug in server -> do not broadcast if we
4037 * Fixed a routing bug. Do not route broadcast packets ever.
4038 Broadcast packets must be processed always and not routed since
4039 they may be destined to some other host than yourself and thus
4040 would get routed without no good reason. Affected file is
4043 * Added function silc_server_config_is_primary_route to check
4044 whether primary router connection has been configured (a router
4045 configuration that we are initiating). If there is not, we
4046 will assume that there is only two routers in the SILC network
4047 and we will use the incoming router connection as our primary
4048 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4050 * Changed the order of the broadcasting. Broadcast _after_ the
4051 packet has been processed not before. Affected file is
4054 * Fixed a [ClientConnection] parsing bug. The port was never
4055 parsed correctly thus resulting to port 0. Affected file
4056 silcd/serverconfig.c.
4058 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4059 argument and did not set the broadcast packet flag. Affected
4060 file silcd/packet_send.c. Fixed same bug in the function
4061 silc_server_send_notify as well.
4063 * If we receive NEW_ID packet for our own ID in the server, ignore
4066 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Removed the nickname from the Private Message Payload.
4071 Updated the code and the protocol specs.
4073 * Updated protocol specs for submitting to the IETF.
4075 * Tweaked the Random Number Generator a bit. Affected file
4076 lib/silccrypt/silcrng.c. Exported a new function
4077 silc_rng_[global]_add_noise which can be used to add more
4080 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Do not parse packets with different timeout when protocol
4083 is active -> may cause problem with rekey. Affected file
4086 * When server receives signoff notify it must not create
4087 new channel key if the client is on any channels since the
4088 sender of the signoff notify will create it.
4090 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Added printing of error messages during SKE protocol from the
4093 failure packet sent by server during SKE. Affected file
4096 * Removed the client's failure_callback handling with timeout
4097 and handle it immediately when received.
4099 * The SKE library returned wrong type in SUCCESS and FAILURE
4100 packets. They must be 32 bit MSB not 16 bit MSB.
4102 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Ok, rewrote the logic of the re-key and now it seems to work.
4105 I tested it on high traffic with frequent re-keys without
4106 problems. Added hmac_receive (and renamed hmac to hmac_send)
4107 in SilcClientConnection in lib/silcclient/client.h and
4108 in SilcIDListData in silcd/idlist.h. Also, removed the
4109 SilcPacketParserContext's cipher and hmac fields as they are
4110 not needed anymore and actually caused some problems when
4111 the ciphers and hmac's changed underneath the packet parser.
4113 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * If re-key protocol is active then process the incoming packets
4116 synchronously since we must assure that icoming packets encrypted
4117 with the old key is processed before the new keys is set to
4118 use. This is true other packets than for REKEY packets.
4119 Affected file silcd/server.c. The same was done to client library
4120 as well, affected file lib/silcclient/client.c.
4122 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Fixed bug in client and server to accept the force send if
4125 the packet is send from silc_[server/client]_packet_process
4126 function. Otherwise the packets are never delivered, oops.
4128 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Disable force sending of packets when REKEY protocol is active.
4131 We must assure that no packet is sent directly when rekey is
4132 performed. All packets must be sent through packet queue.
4133 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4134 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4135 function is silc_[server/client]_packet_send_real to check
4138 * Replaced the SIM paths from example config files to
4139 /usr/local/modules. Also, make install creates now
4140 /usr/local/silc/logs directory to hold all the SILC server
4143 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Made the configure.in.pre work on Solaris. Patch by salo.
4147 * Made all ciphers compatible with non-x86 machines. Defined
4148 CBC mode macros into lib/silccrypt/ciphers_def.h.
4150 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Fixed the make install.
4154 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * When MAC computation fails the silc_packet_decrypt returned 0
4157 even though it was supposed to return -1. Fixed this. The
4158 affected file is lib/silccore/silcpacket.c.
4160 * Do not replace the config files in /etc/silc (in make install)
4161 if they already exist. Affected file ./Makefile.am.
4163 * Do not send re-key packets immediately but through packet queue.
4164 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4166 * Changed silc_net_check_host_by_sock to return FALSE if the
4167 IP/DNS could not be resolved. Though, it returns the IP address
4168 now even if it could not resolve it (but returns also FALSE).
4169 Affected file lib/silcutil/silcnet.[ch].
4171 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Added silc_pkcs_decode_identifier to decode the public key's
4174 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4175 Added also silc_pkcs_free_identifier. Added also new context
4176 SilcPublicKeyIdentifier.
4178 * Added -S option to the silc client. It is used to dump the
4179 contents of the specified public key file.
4181 * Changed the PKCS api to return the public key length when
4182 setting the public key.
4184 * Fixed a fatal bug in the public and private key file loading.
4185 Affected file lib/silccrypt/silcpkcs.c.
4187 * Execute the packet parsing for client with zero (0) timeout
4188 if the protocol is active. Affected file silcd/server.c.
4190 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Made the key generation options to the silcd program. Added
4193 -C option, equivalent to client's option.
4195 * Added new [ServerKeys] config section to the server. It
4196 configures the server's public and private key.
4198 * Defined generic Public Key Payload into the protocol
4199 specification to send specific type of public keys and
4202 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4203 public key or certificate.
4205 * Implemented the GETKEY command to the server and to the
4206 client library and on user interface.
4208 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Made preliminary `make install' work.
4212 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Added SilcServerRekey context into silcd/idlist.h.
4216 * Added the PFS support as defined in the specification to the
4217 SKE protocol. Affected files lib/silcske/*.c.
4219 * Added `ske_group' field to the SilcServerRekey context to hold
4220 the number of the SKE group that is used with PFS in re-key.
4221 Affected file silcd/idlist.h.
4223 * Added PFS re-key support to the server. Affected file is
4226 * Added silc_protocol_cancel to cancel execution of the next
4227 state of the protocol. Affected file is
4228 lib/silccore/silcprotocol.[ch].
4230 * Added the re-key support with and without PFS to the client
4231 library. Re-key is performed once in an hour, by default.
4233 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4234 Added silc_client_rekey_callback and silc_client_rekey_final.
4235 Affected files are lib/silcclient/protocol.[ch] and
4236 lib/silcclient/client.[ch].
4238 * Removed the `hmac_key' and `hmac_key_len' fields from the
4239 SilcClientConnection structure; not needed. Affected file is
4240 lib/silcclient/client.h.
4244 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Do not ask whether user wants to use the negotiated private key
4247 for private messages, just use it. Affected file is
4248 silc/local_command.c.
4250 * Added `send_enc_key' and `enc_key_len' fields to the
4251 SilcIDListData structure since they are needed in the re-key
4252 phase. Affected file is silcd/idlist.[ch].
4254 * Implemented the simple re-key protocol into the server.
4255 Affected files silcd/server.c and silcd/protocol.[ch]. The
4256 re-key will be performed once in an hour, by default.
4258 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4259 Added silc_server_rekey, silc_server_rekey_callback and
4260 silc_server_rekey_final.
4262 * Removed Tunneled flag from the protocol. Updated the code
4263 and the specifications.
4265 * Adde `pfs' field to the SilcIDListData to indicate whether
4266 the PFS is to be performed in the re-key. Affected file is
4269 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4272 int64 of at least the xintXX size. If void * is less that 4
4273 bytes uint32 * will be used. Defined bool as boolean.
4275 * Changed _ALL_ unsigned long and unsigned int to uint32,
4276 unsgined short to uint16 in the source tree.
4278 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4279 not handle clients that has entry->data.registered == FALSE.
4280 They are not in the network anymore. Affected file is
4283 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Implemented the sending of the SERVER_SIGNOFF notify in the
4286 server. Affected file is silcd/server.c.
4288 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4289 Added also silc_notify_payload_encode_args into the
4290 lib/silccore/silcnotify.[ch].
4292 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4293 Affected file silcd/packet_receive.c.
4295 * Implemented the SERVER_SIGNOFF notify handling in the client
4296 library. Affected file lib/silcclient/client_notify.c. Also,
4297 implemnted the printing of the SERVER_SIGNOFF info to the
4298 application. Affected file silc/client_ops.c.
4300 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4301 if the deleting was successful. Affected file silcd/idlist.[ch].
4303 * Added support for public key authentication in the connection
4304 authentication protocol in the client library. Affected file
4305 lib/silcclient/protocol.c.
4307 * Changed the server's silc_idlist_get_clients_by_* interface
4308 to support already allocated array so that new entries may be
4309 added to pre-allocated array. Affected file silcd/idlist.[ch].
4310 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4311 and command replies.
4313 * All command reply functions in the server now calls the
4314 pending command callback even if error occured. This way the
4315 error will be delivered to the client as well. Affected files
4316 silcd/command.c and silcd/command_reply.c.
4318 * Fixed INFO command to return local server's info if no server
4319 was provided. Affected file lib/silcclient/command.c.
4321 * Removed RESTART command for good. Updated the code and the
4324 * Rewrote parts of the task system. It is a bit simpler now.
4325 Removed unsued task priorities. The affected files are
4326 lib/silcutil/silctask.[ch].
4328 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Moved the USERS printing from the library to the application.
4331 Affected files lib/silcclient/command.c and silc/client_ops.c.
4333 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Added channel key re-key support. The re-key is perfomed
4338 only by the router and is done once in an hour. Added `rekey'
4339 field to the SilcChannelEntry in the server. Affected files
4340 silcd/server.c and silcd/idlist.h.
4342 * Added silc_task_unregister_by_context into the file
4343 lib/silcutil/silctask.[ch].
4345 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Added SILC_UMODE_GONE mode to indicate when the client is not
4348 present in the SILC network. Added also support to the local
4349 command AWAY that will set this mode. Added support of showing
4350 "xxx is gone" in WHOIS command. The USERS command shows the
4351 gone status as well.
4353 * Fixed setting server and router operator privileges in the
4354 server's UMODE command. Affected file silcd/command.c.
4356 * Merged the SKE KE1 and KE2 payloads into one payload. The
4357 new KE payload is equivalent to the old KE2 payload.
4359 Cleaned up the SKE Start Payload parsing. It now uses the
4360 simple buffer unformatting to do the parsing. A lot faster
4363 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4364 to the SKE that is used to indicate whether both of the SKE
4365 parties should perform authentication. By default only the
4366 responder performs authentication. By setting this flag also
4367 the initiator must do authentication. By default it is unset
4368 since in normal SKE case, client to server connection, only
4369 the responder should do authentication. When doing SKE between
4370 two clients both should perform authentication. Updated the
4371 code and the protocol specs.
4373 * A little fix to IDENTIFY command in the server. Search the
4374 client first by hash not nickname. Affected file is
4377 * Fixed the silc_client_close_connection to support closing
4378 the client to client connections wihtout deleting too much
4379 data. Affected file lib/silcclient/client.c.
4381 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4382 are received if protocol used to be active but is not anymore
4383 the application would crash due to NULL pointer dereference.
4384 Affected files silcd/server.c and lib/silcclient/client.c.
4386 * Added `hash' field to the SilcClientConnection to include
4387 the hash function negotiated in the SKE protocol.
4389 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4390 to set the channel founder authentication data. A client can
4391 claim the founder rights later by providing the authentication
4392 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4393 This way the channel founder can regain the channel founder
4394 privileges even it is left the channel. This works only on
4395 local server and the client must be connected to the same
4396 server to be able to regain the founder rights. Updated the
4397 protocol specs accordingly.
4399 Added support to the CMODE command in the client to set the
4400 founder auth data. Read the README to see how to set it.
4402 Added support to the CUMODE command to claim the founder
4403 rights. Read the README to see how to do it.
4405 Added support for the founder authentication to the Channel
4406 Entry in the server. Affected file silcd/idlist.h.
4408 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4409 server's CMODE command. Affected file silcd/command.c.
4411 * Added the following new functions into lib/silccore/silcauth.[ch]:
4412 silc_auth_get_method and silc_auth_get_data.
4414 * The server now saves the remote hosts public key to the
4415 SilcIDListData pointer. Affected file silcd/protocol.c.
4417 * The normal server now does not remove the channel entry from
4418 the cache if the founder authentication data is set. It used
4419 to remove it if the founder was the last one on the channel on
4420 the server and left the channel. The auth data is saved and
4421 if the channel is re-joined later the old entry is used with
4422 the old auth data. Affected files silcd/command_reply.c and
4425 * Removed the `pkcs' field from the SilcIDListData structure
4426 in the server; it is not used. Affected file silcd/idlist.h.
4428 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Fixed packet processing on slow links. Partial packets were
4431 never re-processed because the incoming data buffer was cleared
4432 by the application. Application must not directly clear the
4433 sock->inbuf, the packet processing routines handle it. Fixed
4434 this in client library and in server.
4436 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Fixed the WHOIS and IDENTIFY send reply function to really
4439 check whether to send list or just one entry. Affected file
4442 * Cleaned up the LEAVE command's channel key distribution. The
4443 affected file silcd/command.c.
4445 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4446 can enforce the channel mode as well. In that case the ID
4447 includes the ID of the server. The code now enforces the
4448 mode change if the router have different mode than the server.
4450 * The notify client operation with CMODE_CHANGE notify can now
4451 return NULL client_entry pointer if the CMODE was not changed
4452 by client. Application must check for this.
4454 * Added <Server ID> argument to INFO command to support server
4455 info fetching by Server ID.
4457 * Added silc_server_announce_get_channel_users to get assembled
4458 packets of channel users of the specified channel. Affected
4459 file silcd/server.[ch].
4461 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4462 was freed underneath the ID Cache.
4464 * Re-announce clients when the server received CHANNEL_CHANGE
4465 notify from the router. Affected file silcd/packet_send.c.
4467 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4470 crashed since it did not handle the fact that there is no cipher
4471 called "3" and didn't check the error condition. Now fixed.
4473 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4474 flag. It can be used to send message requests.
4476 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Implemented the RESTART command in the client.
4480 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4481 notice type messages. Added notice printing to the user
4484 * The channel keys are not re-generated if the channel's mode
4485 is PRIVKEY, ie private key on the channel exists. Affected
4486 files silcd/server.c and silcd/command.c.
4488 * Fixed a little bug in channel message delivery when channel
4489 private keys are set in the server. Affected file is
4490 silcd/packet_send.c.
4492 * Changed the setting on channel->on_channel = TRUE from the
4493 silc_client_save_channel_key to the JOIN command reply. The
4494 key payload is not received if the private channel key is set.
4495 Affected file lib/silcclient/command_reply.c and the
4496 lib/silcclient/client_channel.c.
4498 * When the CMODE_CHANGE notify is sent and the channel private
4499 key mode is removed the channel key must be re-generated in
4500 other cells as well. Added this support for the router in the
4501 silcd/packet_receive.c.
4503 * Added new local command NOTICE to send notice message on
4504 channel. Affected file silc/local_command.[ch].
4506 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Added new local command ME to the client. It is used to send
4509 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4510 some action. Affected file silc/local_command.[ch].
4512 * Changed channel_message and private_message client operations
4513 to deliver the message flags to the application. Added also
4514 the `flags' arguments to the silc_client_send_channel_message
4515 and silc_client_send_private_message functions. Affected file
4518 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Redefined the Private Message Payload to support private message
4521 keys and to support the new private message flags. Updated
4522 the protocol specs. Flags makes it possible to have for example
4523 CTCP style messages.
4525 * Added new type SilcPrivateMessagePayload and defined an API
4526 for it in the lib/silcclient/silcprivate.[ch].
4528 * Tested private message private keys successfully. Tested the
4529 private message key set, unset and list commands with the new
4532 * Redefined the Channel Message Payload to include the channel
4533 message flags (equal with private message flags) to support
4534 for example CTCP style messages.
4536 * Defined some of the message (for channel and private message)
4537 flags. Updated the protocol specs and added the flags to the
4538 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4540 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Added SilcKeyAgreementStatus type to the key agreement routines
4543 to indicate the current status and error if one occured.
4544 The status types are defined in the lib/silcclient/silcapi.h.
4546 * Added new local command KEY that is used to set and unset private
4547 keys for channels, set and unset private keys for private messages
4548 with remote clients and to send key agreement requests and
4549 negotiate the key agreement protocol with remote client. The
4550 key agreement is supported only to negotiate private message keys,
4551 it currently cannot be used to negotiate private keys for channels,
4552 as it is not convenient for that purpose.
4554 * Fixed a minor pending callback setting bug in the function
4555 silc_client_get_client_by_id_resolve, now the function works.
4556 Affected file lib/silcclient/idlist.c.
4558 * Added function silc_net_get_local_port to get local bound
4559 port by socket. Added to lib/silcutil/silcnet.[ch].
4561 * Added `sockets' and `sockets_count' fields to the SilcClient
4562 object. They hold the sockets of the listenning sockets in
4563 the client. Listenning sockets may be for example the key
4564 agreement server. Affected file lib/silcclient/client.[ch].
4565 Added functions the silc_client_add_socket and the
4566 silc_client_del_socket. They are exported to the application
4569 * Added ~./silc/clientkeys to support other client's public keys.
4571 * Renamed verify_server_key client operation to verify_public_key
4572 and added one argument to indicate the type of the connection
4573 (server, client etc.).
4575 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Added silc_server_connection_auth_request to handle the
4578 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4579 silcd/packet_receive.[ch].
4581 * Added silc_server_send_connection_auth_request into the
4582 silcd/packet_send.c to send the connection auth request packet.
4584 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4587 * Fixed the public key authentication in responder side in the
4588 server. The `auth_data' pointer includes the SilcPublicKey
4589 not the path to the public key. Affected file silcd/protocol.c.
4591 * Implemented the public key authentication in the initiator side
4592 in the server. Affected file silcd/protocol.c.
4594 * Removed the [RedirectClient] config section from the server
4595 configuration. Is not needed and I don't want to implement it.
4597 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Cleaned up the CMODE command in the server. It now works
4600 correctly and supports all the modes defined in the protocol.
4601 Affected file is silcd/command.c.
4603 * Added `hmac_name' field to the SilcChannelEntry in the server
4604 to hold the default HMAC of the channel. It can be set when
4605 creating the channel (with JOIN command). Affected files
4608 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4609 type to indicate the change of the current cipher and hmac
4610 on the channel. Client can safely ignore the <cipher> argument
4611 (if it chooses to do so) since the CHANNEL_KEY packet will
4612 force the channel key change anyway. The <hmac> argument is
4613 important since the client is responsible of setting the new
4614 HMAC and the hmac key into use.
4616 * Fixed the CMODE command in the client library as well.
4618 * Tested CMODE command in router environment successfully.
4620 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Show the version of the remote client (or server) when connecting
4623 to the server. It is logged to the log file. Affected file
4624 is silcd/protocol.c.
4626 * Fixed the KILLED notify handling in the client library. The
4627 client must be removed from all channels when receiving the
4630 Also, do not remove the client entry when giving the KILL
4631 command but when the KILLED notify is received.
4633 * Removed silc_idlist_find_client_by_nickname from the server.
4634 Not needed anymore. Affected files silcd/idlist.[ch].
4636 * Implemented the CHANNEL_CHANGE notify type handling to the
4637 server. Affected file silcd/server.c.
4641 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added silc_server_send_notify_invite to send the INVITE
4644 notify between routers.
4646 * Implemented the INVITE command correctly to the server.
4648 * Implemented the INVITE notify type handling in the server.
4650 * Implemented the INVITE command to the client library and on the
4653 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Added function silc_server_get_client_resolve to find the
4656 client entry by ID from all ID lists and then resolve it
4657 (using WHOIS) if it cannot be found. Affected file is
4660 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Implemented the BAN command to the client library.
4664 * The JOIN command in the server now checks the invite list
4667 * Changed the silc_command_reply_payload_encode_va and the
4668 silc_command_payload_encode_va to support that if argument is
4669 NULL it ignores and checks the next argument. Affected file
4670 lib/silccore/silccommand.c.
4672 * Added silc_server_send_notify_ban to send the BAN notify
4673 type between routers.
4675 * Chaned the silc_notify_payload_encode to support that if
4676 argument is NULL it ignores and checks the next argument.
4677 Affected file lib/silccore/silcnotify.c.
4679 * Tested ban lists in router environment successfully.
4681 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Implemented BAN command to the server, in silcd/command.[ch].
4685 * Removed the BAN and INVITE_LIST modes from the CMODE command
4688 * Added function silc_string_match to regex match two strings.
4689 Affected files lib/silcutil/silcutil.[ch].
4691 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Redefined parts of the SilcChannelEntry in the server to support
4694 the new ban and invite lists.
4696 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Redefined the INVITE command. The same command can be used to
4699 invite individuals to the channel but also to manage the invite
4700 list of the channel (to add to and remove from the invite list).
4701 Updated the protocol specs.
4703 * Added new command SILC_COMMAND_BAN that can be used to manage
4704 the ban list of the channel. Updated the protocol specs.
4706 * Removed the channel modes: the SILC_CMODE_BAN and the
4707 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4708 in the CMODE command. The equivalent features are now available
4709 using INVITE and BAN commands. Updated the protocol specs.
4711 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4712 in the network about change in the current ban list. The notify
4713 type is not used by the client.
4715 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4716 support the invite lists.
4718 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Added new function silc_string_regexify that converts string
4721 including wildcard characters into regex string that can
4722 be used by the GNU regex library. Added into the file
4723 lib/silcutil/silcutil.[ch].
4725 Added silc_string_regex_combine to combine to regex strings
4726 into one so that they can be used as one regex string by
4727 the GNU regex library. Added into the file
4728 lib/silcutil/silcutil.[ch].
4730 Added silc_string_regex_match to match two strings. It returns
4731 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4733 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Imported GNU regex to the soruce tree into lib/contrib.
4736 Fixed some compiler warning from the regex.c.
4738 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Fixed MOTD command in the server to work in router environment.
4742 * Fixed the MOTD command in the client library to support
4743 the server argument in the command.
4745 * Added `nickname_len' argument to the silc_idlist_add_client
4746 in the server, as the `nickname' argument may be binary data
4749 * Added silc_idlist_get_channels to return all channels from
4752 * Implemented LIST command to the server. Affected file is
4755 * Implemented the LIST command to the client library and on the
4758 * Added [<user count>] argument to the LIST command reply.
4759 With private channels the user count is not shown.
4761 * Updated TODO and README.
4763 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * The client entry's data.registered must be TRUE even with
4766 global client entry on global client list. The data.registered
4767 is used to check whether the client is anymore in the network,
4768 for example with WHOWAS command so it must be valid.
4770 * Fixed the WHOWAS command in the server. It now actually works
4771 in router environment. Added function into silcd/command_reply.c
4772 silc_server_command_reply_whowas_save.
4774 * Added silc_idlist_purge function to the silcd/idlist.c
4775 to periodically purge the ID Cache.
4777 * Fixed INFO command in the server. It works now in router
4778 environment. Added <server name> argument to the INFO command
4779 reply. Updated the protocol specs.
4781 * Fixed minor bug in silc_idcache_purge to not purge if the
4782 expire value is zero.
4784 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4785 they were buggy because of the WHOWAS information.
4787 * Fixed local command MSG to handle the async resolving of
4788 the remote client properly. It used to fail the first MSG.
4789 Affected file silc/local_command.c.
4791 * Added `data_len' field to SilcIDCache context.
4793 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Update TODO. Todo in commands in the server.
4797 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4800 used by routers as broadcast packet to inform other routers
4801 about the changed user mode.
4803 Implemented the notify handling in the server. Affected file is
4804 silcd/packet_receive.c. Added the function
4805 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4807 * Added new generic Channel Payload and deprecated the New Channel
4808 Payload. The New Channel Payload is now the generic Channel
4811 * Added new argument `mode' to the silc_server_send_new_channel
4812 as it is required in the Channel Payload now.
4814 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4815 and created a new and real SilChannelPayload to represent the
4816 new generic Channel Payload. Implemented the encode/decode
4817 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4819 * Added silc_server_get_client_channel_list to return the list
4820 of channels the client has joined for WHOIS command reply.
4821 Affected file silcd/server.[ch].
4823 * Implemented the channel list sending in the WHOIS command reply
4824 in server and in the client.
4826 Implemented the channel list displaying on the user interface
4827 as well. Affected file silc/client_ops.c.
4829 * Added silc_channel_payload_parse_list to parse list of Channel
4830 Payloads. It returns SilcDList list of SilcChannelPayloads.
4831 Client for example can use this function to parse the list of
4832 channels it receives in the WHOIS command reply. The caller
4833 must free the list by calling silc_channel_payload_list_free.
4834 Affected files lib/silccore/silcchannel.[ch].
4836 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Added one new argument <user mode> to the WHOIS command reply
4839 to return the mode of the user in SILC. Updated the protocol
4842 Implemented it to the server and client.
4844 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Fixed the mode printing on the user interface on joining.
4847 Affected file silc/client_ops.c.
4849 * Implemented the UMODE command and user modes in general to the
4850 client library and to the user interface.
4852 * Implemented the UMODE command to the server.
4854 * The server now sends UNKNOWN_COMMAND error status if client sends
4855 unknown command. Affected file silcd/command.c.
4857 * All server commands now handle the command identifier the right
4858 way when sending the command reply to the client. The client can
4859 use to identify the command replies with the identifier.
4861 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added silc_server_get_client_route to resolve the route to
4864 the client indicated by the client ID. Affected file is
4867 * Added silc_server_relay_packet as general function to relay
4868 packet to arbitrary destination. This deprecates functions
4869 like _send_private_message_key, _relay_notify etc. Affected
4870 file is silcd/packet_send.[ch].
4872 Removed silc_server_send_key_agreement,
4873 silc_server_send_private_message_key and
4874 silc_server_packet_relay_notify functions from the file
4875 silcd/packet_send.[ch].
4879 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4880 server. Affected file silcd/packet_receive.[ch].
4882 * Implemented the KILL command to the client. Implemented the
4883 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4884 Affected files lib/silcclient/command[_reply].c and
4885 lib/silcclient/client_notify.c. Implemented the KILL notify
4886 printing in the user inteface.
4888 * Fixed a lot silc_parse_nick memory leaks from the client
4889 library in the file lib/silcclient/command.c.
4891 * Changed the silc_server_send_notify_on_channels's `sender'
4892 argument from SilcSocketConnection to SilcClientEntry to
4893 check the sender as entry and not as connection object and not
4894 to send to the client provided as argument. The affected file
4895 is silcd/packet_send.[ch].
4897 * The notify packets that are destined directly to the client used
4898 to not to be processed by the server. Now changed that and the
4899 server processes all notify packets. After relaying the packet
4900 to the client the notify packet is processed in the server.
4902 * The silc_server_free_client_data now checks whether there is
4903 pending outgoing traffic for the client and purges the data to
4904 the network before removing the client entry.
4906 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4909 an client is killed from the SILC Network. Updated the protocol
4912 Added new function silc_server_send_notify_killed to the
4913 silcd/packet_send.[ch].
4915 * Added function silc_server_packet_relay_notify to relay notify
4916 packets that are destined directly to a client. In this case
4917 the server does not process the notify packets but merely relays
4918 it to the client. Affected file silcd/packet_send.[ch].
4920 Added also silc_server_packet_process_relay_notify to check
4921 whereto relay the notify. Affected file is
4922 silcd/packet_receive.[ch].
4924 * Implemented the KILL command to the server.
4928 * Added the backup schema desgined last fall to the protocol
4929 specs for everyone to see. The specification is in the
4930 *-spec-xx.txt draft and the packet type definitions for the
4931 backup routers is in *-pp-xx.txt draft. Thusly, added also
4932 new packet type SILC_PACKET_CELL_ROUTERS.
4934 * A big security problem in the implementation discovered. The
4935 signoff of an client did not cause new channel key generation
4936 which it of course should've done. The channel keys must be
4937 always re-generated when client leaves (or signoffs) the channel.
4938 The silc_server_remove_from_channels funtion now handles
4939 the channel key re-generation.
4941 * Added `sender' argument to the silc_server_send_notify_on_channels
4942 to not to send the client provided as argument. Affected file
4943 silcd/packet_send.[ch].
4945 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Implemented OPER and SILCOPER commands into the server and
4950 * Added silc_auth_verify and silc_auth_verify_data to verify
4951 the authentication directly from the authentication payload.
4952 It supports verifying both passphrase and public key based
4953 authentication. Affected file lib/silccore/silcauth.[ch].
4955 * Added `hash' field to the SilcIDListData structure. It is the
4956 hash negotiated in the SKE protocol. Affected file is
4959 * Slight redesigning of the SilcAuthPayload handling routines.
4960 Do not send SilcPKCS but SilcPublicKey as argument.
4962 * Implemented the public key authentication support to the
4963 serverconfig. The public key is loaded from the provided path
4964 and saved as authentication data to void * pointer. Thus,
4965 changed the unsigned char *auth_data to void *auth_data;
4967 * Fixed SHUTDOWN command to send the reply before the server
4968 is shutdown. :) Affected file silcd/command.c.
4970 * Fixed fatal bug in CONNECT command. The hostname was invalid
4971 memory and server crashed. Affected file silcd/command.c.
4973 * Fixed fatal bug in CLOSE command. The server_entry became
4974 invalid but was referenced later in the command. Affected file
4977 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Fixed fatal bug in failure packet handling. Server ignored
4980 the failure and thus crashed when it came.
4984 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4987 that the command may be executed only once in (about) 2 seconds.
4988 The old SILC_CF_LAG flag is same but allows command bursts up
4989 to five before limiting.
4991 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4992 server code. Various commands now includes the CF_LAG_STRICT
4993 flag to disallow any kind of miss-use of the command.
4995 * Fixed the silc_buffer_unformat to not to allocate any data
4996 if the length of the data is zero. It used to allocate the
4997 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4999 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Changed the format of AdminConnection configuration section
5002 in the server. Added username of the admin to the format.
5003 Affected files silcd/serverconfig.[ch].
5005 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5006 to return admin configuration data by host, username and/or
5009 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Implemented WHOWAS command to the server. Added the functions:
5013 silc_server_command_whowas_parse,
5014 silc_server_command_whowas_send_reply,
5015 silc_server_command_whowas_from_client and
5016 silc_server_command_whowas_from_server
5018 * Added <Client ID> argument to the WHOWAS command reply. Updated
5019 the protocol specs accordingly.
5021 * Implemented WHOWAS command and command_reply to the client
5024 Implemented the WHOWAS printing on the user interface.
5026 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5028 * Added new argument to the WHOWAS command reply, the real name.
5029 It is an optional argument. Updated the protocol specs.
5031 * Added SilcIDCacheDestructor callback that is registered when
5032 the SilcIDCache is allocated. The callback is called when
5033 an cache entry in the ID Cache expires, or is purged from the
5034 cache. Added into lib/silccore/idcache.[ch].
5036 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5037 to destruct the client entries when the cache entry expires.
5038 Other ID Cache's in server and in the client library ignores
5041 * If the ID Cache entry's `expire' field is zero then the entry
5042 never expires. Added boolean `expire' argument to the
5043 silc_idcache_add function in the lib/silccore/idcache.[ch].
5044 If it is TRUE the default expiry value is used.
5046 * Added silc_server_free_client_data_timeout that is registered
5047 when client disconnects. By default for 5 minutes we preserve
5048 the client entry for history - for WHOWAS command.
5050 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Added support to the server to enforce that commands are not
5053 executed more than once in 2 seconds. If server receives
5054 commands from client more frequently, timeout is registered
5055 to process the commands. Affected file silcd/command.c.
5056 Added new function silc_server_command_process_timeout.
5058 * Changed NICK_NOTIFY handling in client library to check that
5059 if the client's nickname was changed, so there is no need to
5060 resolve anything from the server.
5062 * Removed error printing from the WHOIS and IDENTIFY commands.
5063 If error occurs then it is ignored silently in the client library.
5064 The application, however, may map the received error to
5065 human readable error string. The application currently maps
5066 the NO_SUCH_NICKNAME error to string.
5068 * Made the command status message public to the application. Moved
5069 them from lib/silcclient/command_reply.c to
5070 lib/silcclient/command_reply.h. The application can map the
5071 received command status to the string with the
5072 silc_client_command_status_message function.
5074 * Added check to the server to check that client's ID is same
5075 as the Source ID in the packet the client sent. They must
5078 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Added dist-bzip hook to the Makefile.am to make bzip2
5081 compressed distributions.
5083 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Server now enforces the maximum length for the nickname and
5086 the channel as protocol specification dictates. 128 bytes for
5087 nickname and 256 bytes for channel name.
5089 * Moved the WHOIS printing to the application. The client libary
5090 does not print out the WHOIS information anymore, the application
5091 must do it. Renamed silc_client_command_reply_whois_print to
5092 the silc_client_command_reply_whois_save.
5094 The client's idle time is also sent to the application now, and
5095 the idle is shown on screen.
5097 * Added silc_client_command_reply_identify_save to save the
5098 received IDENTIFY entries.
5100 * Do not check for channel private keys in message sending and
5101 reception if the channel does not have the PRIVKEY mode set.
5102 Affected file lib/silclient/client_channel.c.
5104 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5107 just surfaced after chaning the JOIN procedure.
5109 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Added silc_client_get_clients_by_list to get client entries
5112 from Client ID list, that is returned for example by JOIN
5113 and USERS command replies. The application should use this
5114 function for example when JOIN command reply is received to
5115 resolve the clients already on the channel (library does not
5116 do that anymore as USERS command reply is not used in the JOIN
5117 procedure anymore). Affected files lib/silcclient/silcapi.h and
5118 lib/silcclient/idlist.c.
5120 * JOIN command reply and USERS command reply returns now SilcBuffer
5121 pointers instead of unsigned char pointers when returning
5122 the client list and mode list.
5124 * Added <Client ID> argument to the JOIN command reply, mainly
5125 for the server to identify for which client the command was
5126 originally sent. Updated protocol specs accordingly.
5128 * Added SilcDlist private_key pointer to the SilcChannelEntry
5129 in the client to support the channel private keys. Affected
5130 file is lib/silcclient/idlist.h.
5132 * Added SilcChannelPrivateKey argument to the function
5133 silc_client_send_channel_message so that application can choose
5134 to use specific private ke if it wants to. If it is not provided,
5135 the normal channel key is used, unless private keys are set.
5136 In this case the first (key that was added first) is used
5137 as the encryption key.
5139 * Implemented the support for channel private key handling.
5140 Implemented the following functions:
5142 silc_client_add_channel_private_key,
5143 silc_client_del_channel_private_keys,
5144 silc_client_del_channel_private_key,
5145 silc_client_list_channel_private_keys and
5146 silc_client_free_channel_private_keys
5148 Affected file lib/silcclient/client_channel.c.
5150 * Added the support for the private keys in the channel message
5151 sending and encryption and in the message reception and
5152 decryption. Affected funtions are
5153 silc_client_send_channel_message and silc_client_channel_message.
5155 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Added SKE's key verify callback to the client library's
5158 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5160 * Removed the statement that server (or router) must send USERS
5161 command reply when joining to the channel so that the client
5162 knows who are on the channel. Instead, the client list and
5163 client's mode list is now sent in the JOIN command reply to the
5164 client who joined channel. This is better solution.
5166 * Added function silc_server_get_users_on_channel and function
5167 silc_server_save_users_on_channel to the silcd/server.[ch].
5169 * Removed function silc_server_command_send_users from the
5172 * Do not show topic on the client library anymore. The topic is
5173 sent in the command reply notify to the application and the
5174 application must show the topic now.
5176 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Added client searching by nickname hash into the IDENTIFY and
5179 WHOIS commands in the server as they were clearly missing from
5180 them. Affected file is silcd/command.c.
5182 * Fixed a bug in private message receiving in the client library.
5183 The remote ID was freed and it wasn't supposed, now it is
5186 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Minor fix to the channel payload; allocate the data area, as it
5189 needs to be of specific length.
5191 * If the key agreement port is zero then the operating
5192 system will define the bound port. Affected files are
5193 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5195 * Added new function silc_channel_payload_decrypt into the file
5196 lib/silccore/silcchannel.[ch].
5198 * Moved the channel message etc, check from silc_packet_decrypt
5199 to applications. The library calls now a generic
5200 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5201 when the packet is either normal or special. This was done to
5202 allow more wide range of checking that was not allowed when
5203 the code was in library. Now applications can do virtually any
5204 checks to the packet and return to the library the decision how
5205 the packet should be processed. Affected files are
5206 lib/silccore/silcpacket.[ch].
5208 Added silc_server_packet_decrypt_check to the server and
5209 silc_client_packet_decrypt_check to the client library.
5211 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5212 to send with specified source and destination information.
5214 * Channel message delivery between routers was broken after the
5215 channel key distribution was fixed earlier. The channel key
5216 was used be to distributed to other routers as well which is not
5217 allowed by the protocol. Now this is fixed and channel keys
5218 really are cell specific and the channel message delivery between
5219 routers comply with the protocol specification.
5221 * Fixed various commands in server to check also the global list
5222 for the channel entry and not just the local list. The affected
5223 file silcd/command.c.
5225 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Added assert()s to buffer formatting and unformatting routines
5228 to assert (if --enable-debug) when error occurs. Affected
5229 file: lib/silcutil/silcbuffmt.c.
5231 * Changed to auto-reconnect to check whether the remote host is
5232 router and register the re-connect timeout if it is. It used
5233 to check that whether we are normal server, but router must do
5234 auto-reconnect with another router as well. Affected file
5237 * Removed the [<key len>] option from CMODE command as the cipher
5238 name decides the key length, nowadays. See the defined ciphers
5239 from the protocol specification.
5241 * Added [<hmac>] option to the CMODE command to define the HMAC
5242 for the channel. Added SILC_CMODE_HMAC channel mode.
5244 * Added [<hmac>] option for the JOIN command so that user can
5245 select which HMAC is used to compute the MACs of the channel
5248 * Added Hmac field to the Channel Message Payload. The integrity
5249 of plaintext channel messages are now protected by computing
5250 MAC of the message and attaching the MAC to the payload. The
5251 MAC is encrypted. Now, it is clear that this causes some
5252 overhead to the size of the packet but rationale for this is that
5253 now the receiver can verify whether the channel message decrypted
5254 correctly and also when private keys are set for the channel the
5255 receiver can decrypt the packet with several keys and check from
5256 the MAC which key decrypted the message correctly.
5258 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5259 lib/silccrypt/silccipher.[ch].
5261 * Added silc_hash_len to return the digest length into the
5262 lib/silcrypt/silchash.[ch].
5264 * Rewrote parts of Silc Channel Payload interface in the
5265 lib/silccore/silcchannel.[ch]. The encode function now also
5266 encrypts the packet and parse function decrypts it.
5268 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Fixed a minor formatting bug in the SKE's key material processing.
5271 It actually might have processed the keys wrong way resulting
5274 * Redefined the mandatory HMAC algorithms and added new algorithms.
5275 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5276 and hmac-md5 truncated to 96 bits. The mandatory is now
5277 hmac-sha1-96. Rest are optional (including the one that used
5278 to be mandatory). Rationale for this is that the truncated HMAC
5279 length is sufficient from security point of view and can actually
5280 make the attack against the HMAC harder. Also, the truncated
5281 HMAC causes less overhead to the packets. See the RFC2104 for
5284 * Added new [hmac] configuration section. The SKE used to use
5285 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5286 is of course wrong. The official names that must be proposed in
5287 the SKE are the ones defined in the protocol specification
5288 (hmac-sha1-96 for example). The user can configure any hmac
5289 using any hash function configured in the [hash] section. At
5290 least, the mandatory must be configured.
5292 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5294 * Added HMAC list to the SKE proposal list. It has now both
5295 hash algorithm list and HMAC list. This makes the protocol
5296 incompatible with previous versions. The SKE now seems to work
5297 the way it is supposed to work, for the first time actually.
5299 * Defined plain Hash algorithms to the protocol specification.
5302 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Implemented support for key agreement packets into the server.
5305 Added functions silc_server_key_agreement and
5306 silc_server_send_key_agreement. Other than these functions,
5307 server has nothing to do with this packet.
5309 * Added support for private message key packets into the server.
5310 Added functions silc_server_private_message_key and
5311 silc_server_send_private_message_key.
5315 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5316 called in the protocol's final callback instead in the END
5317 protocol state. This makes a little more sense and in the same
5318 time in client we can use the same protocol routines for normal
5319 key exchange and to key agreement packet handling as well.
5321 * Added to both client's and server's KE protocol context the
5322 SilcSKEKeyMaterial pointer to save the key material. We will
5323 bring the key material to the protocol's final callback by doing
5324 this. The final callback must free the key material.
5326 * Added SKE's packet_send callback into client's KE protocol
5327 context so that the caller can choose what packet sending function
5328 is used. This way we can use different packet sending when
5329 doing normal SKE when doing key agreement packet handling (in
5330 the key agreement packet handling we do not want to encrypt
5333 * Implemented the responder side of the key agreement routines
5334 in the client. The client can now bind to specified port and
5335 accept incoming key negotiation. The key material is passed
5336 to the application after the protocol is over.
5338 * Implemented the processing of incoming Key Agreement packet
5339 in the client. Added function silc_client_key_agreement to
5342 * Implemented the intiator side of the key agreement routines
5343 in the client. The client can now initiate key agreement with
5344 another remote client. The key material is passed to the
5345 application after the protocol is over.
5347 * Created client_keyagr.c to include all the key agreement
5350 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5351 SILC_TASK_CALLBACK except that it is not static.
5353 * Created client_notify.c and moved the Notify packet handling
5354 from the client.[ch] into that file.
5356 * Created client_prvmsg.c and moved all private message and
5357 private message key routines from the client.[ch] into that file.
5359 * Create client_channel.c and moved all channel message and
5360 channel private key routines from the client.[ch] into that file.
5362 * Changed silc_client_get_client_by_id_resolve to resolve with
5363 WHOIS command instead of IDENTIFY command, in the file
5364 lib/silclient/idlist.c.
5366 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Implemented the SKE's responder side to the Client library.
5370 * When FAILURE is received to the protocol do not trust it
5371 blindly. Register a timeout to wait whether the remote closes
5372 the connection as it should do it, only after that process the
5373 actual failure. This was changed to both client and server.
5375 * Added client_internal.h to include some of the structures
5376 there instead of client.h in lib/silcclient/.
5378 * Added function silc_task_unregister_by_callback to unregister
5379 timeouts by the callback function.
5381 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Some "Incomplete WHOIS info" errors has been appearing on the
5384 log files. Took away the entry->userinfo check from WHOIS
5385 reply sending. The entry->userinfo is now " " if client did not
5386 provide one. I thought this was fixed earlier but something
5387 is wrong still. Let's see if the error still appears.
5389 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Fixed a minor bug in the login when the channel key is
5392 re-generated in the server. It used to generate the key in
5393 wrong order and thus caused problems in the channel traffic.
5395 * Fixed a minor bug in channel key distsribution after
5396 KICK command. The key was not sent to the router even though
5399 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Added silc_ske_process_key_material_data as generic routine
5402 to process any key material as the SILC protocol dictates. The
5403 function is used by the actual SKE library but can be used by
5404 applications as well. This relates to the private message keys
5405 and the channel private keys since they must be processed the
5406 same way the normal SILC session keys. The protocol dictates
5407 this. Affected files: lib/silcske/silcske.[ch].
5409 Added also silc_ske_free_key_material to free the
5410 SilcSKEKeyMaterial structure.
5412 * Defined silc_cipher_set_key function to set the key for
5413 cipher without using the object's method function. The affected
5414 files: lib/silccrypt/silccipher.[ch].
5416 * Implemented silc silc_client_add_private_message_key,
5417 silc_client_add_private_message_key_ske,
5418 silc_client_del_private_message_key,
5419 silc_client_list_private_message_keys and
5420 silc_client_free_private_message_keys functions in the
5423 Added functions silc_client_send_private_message_key to send
5424 the Private Message Key payload and silc_client_private_message_key
5425 to handle incoming Private Message Key payload.
5427 * Added Cipher field to the Private Message Key payload to set
5428 the cipher to be used. If ignored, the default cipher defined
5429 in the SILC protocol (aes-256-cbc) is used.
5431 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Removed lib/silcclient/ops.h file.
5435 Redefined parts of the SILC Client Library API. Created new
5436 file silcapi.h that deprecates the ops.h file and defines the
5437 published Client Library API. Defined also private message key
5438 API and channel private key API into the file.
5440 This is the file that the application must include from the
5441 SILC Client Library. Other files need not be included by
5442 the application anymore.
5444 * Added new key_agreement client operation callback and also
5445 defined the Key Agreement library API for the application.
5447 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5450 is used by clients to request key negotiation between another
5451 client in the SILC network. If the negotiation is started it
5452 is performed using the SKE protocol. The result of the
5453 negotiation, the secret key material, can be used for example
5454 as private message key.
5456 Implemented the Key Agreement payload into the files
5457 lib/silccore/silauth.[ch].
5459 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Redefined ciphers for the SILC protocol. Added some new ciphers
5462 and defined the key lengths for the algorithms. Changed the
5463 code accordingly. The default key length is now 256 bits.
5465 * Fixed SKE key distribution function silc_ske_process_key_material
5466 when the key length is more than 128 bits. The default key
5467 length in SILC is now 256 bits.
5469 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5470 to indicate unsupported algorithm.
5472 * Renamed rijndael.c to aes.c and all functions as well.
5474 * Fixed a long standing channel key setting bug in client library.
5475 Weird that it has never surfaced before.
5477 * Fixed bug in channel deletion. If the entire channel is removed
5478 then it must also delete the references of the channel entry
5479 from the client's channel list as the client's channel entry and
5480 the channel's client entry share same memory.
5482 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Implemented CONNECT and SHUTDOWN commands in the client.
5486 * Implemented CLOSE command to the client.
5488 * Added the function silc_idlist_find_server_by_name into the
5489 files silcd/idlist.[ch].
5491 Added the function silc_idlist_find_server_by_conn into the
5492 files silcd/idlist.[ch].
5494 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * DIE command was renamed to SHUTDOWN. Updated the both code
5499 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5500 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5502 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5505 * Added function silc_server_create_connection function to create
5506 connection to remote router. My server implementation actually
5507 does not allow router to connect to normal server (it expects
5508 that normal server always initiates the connection to the router)
5509 so the CONNECT command is only good for connecting to another
5512 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5515 or some other client was kicked from the channel.
5517 Implemented the handling of the notify type to both client
5520 Implemented silc_server_send_notify_kicked to send the KICKED
5521 notify. It is used to send it to the server's primary router.
5523 * Implemented the KICK command into server and client.
5525 * Added `query' argument to the silc_idlist_get_client function
5526 to indicate whether to query the client from server or not if
5529 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5530 to indicate that the client is not channel founder.
5534 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Removed the rng context from SilcPacketContext structure and
5537 changed that the packet routine uses the Global RNG API.
5539 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Added support for quit message that client can "leave" on the
5542 channel when it quits the SILC. It is ditributed inside the
5543 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5545 Added silc_server_free_client_data that will take the
5546 signoff message as argument.
5548 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5550 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Updated parts of the protocol specification to keep it up
5555 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5558 payloads in one packet.
5560 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5561 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5562 use now the new List flag.
5564 * Also deprecated the following packet types: REPLACE_ID,
5565 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5567 * Added list support for Notify packet in server.
5569 * Added silc_server_send_notify_channel_change to send the
5570 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5571 the silc_server_send_replace_id.
5573 * Added silc_server_send_notify_nick_change to send the
5574 NICK_CHANGE notify type. Deprecates the function
5575 silc_server_send_replace_id.
5577 * Added silc_server_send_notify_join to send the JOIN notify type.
5578 Deprecates the function silc_server_send_new_channel_user.
5580 * Added silc_server_send_notify_leave to send LEAVE notify type.
5581 Deprecates the function silc_server_send_remove_channel_user.
5583 * Added silc_server_send_notify_cmode and
5584 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5585 types. Deprecates the silc_server_send_set_mode function.
5587 * Added SERVER_SIGNOFF notify type to indicate that server has
5588 quit. This means that all clients on the channel from that
5589 server will drop. This can be also used when netsplit happens.
5591 Deprecated REMOVE_ID packet type since it is not needed anymore
5594 Added silc_server_send_notify_server_signoff to send the
5595 SERVER_SIGNOFF notify type. Deprecates the function
5596 silc_server_send_remove_id.
5598 Added also silc_server_send_notify_signoff to send the
5599 SIGNOFF notify type.
5601 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5602 SILC protocol from this day on. Changed the protocol
5603 specification as well.
5605 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5606 notify type. It is used between routers to notify about
5607 topic changes on a channel.
5609 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5612 * Partly updated the protocol specification to comply with the
5613 changes now made. It is still though a bit outdated.
5615 * The JOIN notify type now takes one extra argument <Channel ID>.
5616 The packet used to be destined to the channel but now the
5617 JOIN type may be sent as list thus it is impossible to
5618 destine it to any specific channel. By adding this argument
5619 it is again possible.
5621 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Added CREDITS file. The CHANGES and CREDITS file will appear
5624 in the distribution as well.
5626 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5629 types in the server's silcd/packet_receive.c.
5631 * Implemented CMODE and CUMODE to work in router environment.
5633 * Fixed minor encoding and decoding buglet from the
5634 lib/silccore/silcmode.c.
5636 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5639 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5641 * Changed all SilcConfigServer* and silc_config_server* to
5642 SilcServerConfig* and silc_server_config*, respectively.
5645 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Associated the ID (client or server ID) to the Authentication
5648 Payload to avoid any possibility of forging. Updated the
5649 protocol specification and the code accordingly.
5651 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * The RSA key length is now save to the RsaKey context in the
5654 key generation process in lib/silccrypt/rsa.c. The key length
5655 is now used to figure out the maximum size of the block allowed
5656 to be encrypted/signed.
5658 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5659 is equivalent to the silc_mp_mp2bin but does not allocate any
5662 * Changed silc_mp_mp2bin API to take length argument. If it is
5663 non-zero then the buffer is allocated that large. If zero, then
5664 the size is approximated using silc_mp_sizeinbase, which however
5667 * Created Global RNG API which is global RNG that application can
5668 initialize. After initializing, any routine anywhere in the
5669 code (including library) can use RNG without allocating a new
5670 RNG object. This was done to allow this sort of use of the
5671 RNG in code that has no chance to allocate RNG object. All
5672 applications currently allocate this and many routines in the
5673 library use this. Affected file lib/silccrypt/silcrng.[ch].
5675 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5676 it to use the Global RNG API.
5678 * Defined Authentication Payload into protocol specification that
5679 is used during SILC session to authenticate entities. It is
5680 used for example by client to authenticate itself to the server
5681 to obtain server operator privileges.
5683 Implemented this payload into the lib/silccore/silcauth.[ch].
5684 Implemented also routines for public key based authentication
5685 as the new protocol specification dictates.
5687 Moved definitions of different authentication methods from
5688 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5690 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5691 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5692 silc_pkcs_verify_with_hash functions into the file
5693 lib/silccrypt/silcpkcs.[ch].
5695 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * The client entry's userinfo pointer must be always valid.
5698 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5699 will fail since it requires the userinfo. Now, the userinfo
5700 is allocated as "" if actual userinfo does not exist. Actually,
5701 it must exist and it is totally Ok to drop client connections
5702 that does not announce the userinfo. However, we will make
5703 this workaround for now.
5705 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5706 to return the remote port by socket.
5708 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5711 SILC_SERVER_PENDING_EXEC and added an new macro
5712 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5713 data or when error occurs while processing the pending command.
5715 Added new argument `destructor' into silc_server_command_pending
5716 and to the SilcServerCommandPending object. This destructor is
5717 now called after calling the pending callback or if error occurs
5718 immediately. If error occurs the actual pending callback won't
5719 be called at all - only the destructor. The destructor may be
5720 NULL if destructor is not needed.
5722 All this applies for client library code as well. Similar
5723 changes were made there as well for the pending commands.
5725 In the client, the application must now allocate the
5726 SilcClientCommandContext with the silc_client_command_alloc
5729 * Added reference counter to the SilcServerCommandContext. Added
5730 function silc_server_command_alloc and silc_server_command_dup
5733 Same type of functions added to the client library for the same
5736 * Removed the cmd_ident from IDListData away since it is now
5737 global for all connections. It is the command identifier used
5738 in command sending and with pending commands. The affected file
5741 * Added reference counter to the SilcSocketConnection objecet to
5742 indicate the usage count of the object. The object won't be
5743 freed untill the reference counter hits zero. Currently only
5744 server uses this, and client ignores it. The client must be
5745 set to use this too later. The affected files are
5746 lib/silccore/silcsockconn.[ch]. Added also the function
5747 silc_socket_dup to increase the reference counter.
5749 This was mainly added because it is possible that the socket
5750 is removed underneath of pending command or other async
5751 operation. Now it won't be free'd and proper DISCONNECTING
5752 flags, etc. can be set to avoid sending data to connection that
5753 is not valid anymore.
5755 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5756 the connection. After that it sets SILC_SET_DISCONNECTED.
5757 It is, however, possible that the socket data is not still freed.
5758 The silc_server_packet_process now checks that data is not
5759 read or written to connection that is DISCONNECTED. The socket
5760 get's freed when the reference counter hits zero.
5762 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Changed the client operation API: channel_message operation's
5765 `sender' is now the client entry of the sender, not the nickname
5766 and the `channel' is the channel entry, not the channel name.
5768 In the private_message operation the `sender' is now also the
5769 client entry of the sender not the nickname.
5771 Affected file is lib/silcclient/ops.h and all applications
5772 using the client operations.
5774 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Moved the calling of ops->connect() from connect_to_server_final
5777 into receive_new_id functin since that is the point when the
5778 client is actually allowed to send traffic to network. The
5779 affected file is lib/silcclient/client.c.
5781 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5784 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5785 (if needs broadcasting) instead of broadcasting the packets one
5786 by one which would make a burst in the network traffic.
5788 * Added `broadcast' argument to the functions in silcd/server.[ch]
5789 silc_server_create_new_channel[_with_id] to indicate whether
5790 to send New Channel packet to primary router.
5792 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Added new function into the silcd/server.[ch] files:
5795 silc_server_create_new_channel_with_id to create new channel with
5796 already existing Channel ID.
5798 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5799 lib/silccore/silcpacket.h. This packet is used t send list of
5800 Set Mode payloads inside one packet. Server uses this to set
5801 the modes for the channels and clients on those channels, that it
5802 announced to the router when it connected to it. The protocol
5803 specification has been updated accordingly.
5805 * The silc_server_new_channel did not handle the packet coming
5806 from normal server as it normally does not send that. However,
5807 when it announces its channels it does send it. Implemented
5808 the support for that.
5810 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5811 into the file lib/silccore/id.h.
5813 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Fixed memory leaks in the functions silc_idlist_del_client,
5816 silc_idlist_del_channel and silc_idlist_del_server in the file
5817 silcd/idlist.c. All of those leaked like a sieve.
5819 * Fixed some small memory leaks in the client's function
5820 silc_client_notify_by_server.
5822 * Added functions into silcd/server.c: silc_server_announce_clients,
5823 silc_server_announce_channels and silc_server_announce_server.
5824 These functions are used by normal and router server to announce
5825 to its primary router about clients, channels and servers (when
5826 router) that we own. This is done after we've connected to the
5829 These functions effectively implements the following packet types:
5830 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5831 and SILC_PACKET_NEW_ID_LIST.
5833 * Added new functions into the silcd/packet_receive.[ch]:
5834 silc_server_new_id_list, silc_server_new_channel_list and
5835 silc_server_new_channel_user_list to handle the incoming
5836 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5838 * Added support of changing Channel ID in the function
5839 silc_server_replace_id. If the server that announces a channel
5840 to the router already exists in the router (with same name but
5841 with different Channel ID), router is responsible to send
5842 Replace ID packet to the server and force the server to change
5843 the Channel ID to the one router has.
5845 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5846 client that the Channel ID has been changed by the router. The
5847 normal server sends this to the client. Client must start using
5848 the new Channel ID as the channel's ID.
5850 Implemented handling of this new type into lib/silcclient/client.c
5851 into the function silc_client_notify_by_server.
5853 * Added new function silc_idlist_replace_channel_id into the files
5854 silcd/idlist.[ch] to replace the Channel ID.
5856 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Call silc_server_command_identify_check always when processing
5859 the IDENTIFY command in silcd/command.c
5861 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5864 send keepalive packets. The packet can be sent by clients,
5865 servers and routers.
5867 Added function silc_socket_set_heartbeat into the file
5868 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5869 If not set, the heartbeat is not performed. The actual
5870 heartbeat is implemented in the low level socket connection
5871 library. However, application is responsible of actually
5874 Added silc_server_send_heartbeat to send the actual heartbeat
5875 packet into silcd/packet_send.[ch]. Server now performs
5876 keepalive with all connections.
5878 * Added silc_task_get_first function into lib/silcutil/silctask.c
5879 to return the timeout task with shortest timeout. There was a bug
5880 in task unregistration that caused problems. TODO has been
5881 updated to include that task system must be rewritten.
5883 * The client library will now resolve the client information when
5884 receiving JOIN notify from server for client that we know but
5885 have incomplete information.
5887 * Rewrote parts of silc_server_remove_from_channels and
5888 silc_server_remove_from_one_channel as they did not remove the
5889 channel in some circumstances even though they should've.
5891 * Encryption problem encountered in server:
5893 The LEAVE command used to send the Channel Key packet to the
5894 router immediately after generating it. However, the code
5895 had earlier sent Remove Channel user packet but not immediately,
5896 ie. it was put to queue. The order of packets in the router
5897 was that Channel Key packet was first and Remove Channel User
5898 packet was second, even though they were encrypted in the
5899 reverse order. For this reason, MAC check failed. Now, this
5900 is fixed by not sending the Channel Key packet immediately but
5901 putting it to queue. However, this is more fundamental problem:
5902 packets that are in queue should actually not be encrypted
5903 because packets that are sent immediately gets encrypted
5904 actually with wrong IV (and thus MAC check fails). So, packets
5905 that are in queue should be encrypted when they are sent to
5906 the wire and not when they put to the queue.
5908 However, the problem is that the current system has not been
5909 designed to work that way. Instead, the packet is encrypted
5910 as soon as possible and left to the queue. The queue is then
5911 just purged into wire. There won't be any fixes for this
5912 any time soon. So, the current semantic for packet sending
5915 o If you send packet to remote host and do not force the send
5916 (the packet will be in queue) then all subsequent packets to the
5917 same remote host must also be put to the queue. Only after the
5918 queue has been purged is it safe again to force the packet
5921 o If you send all packets immediately then it safe to send
5922 any of subsequent packets through the queue, however, after
5923 the first packet is put to queue then any subsequent packets
5924 must also be put to the queue.
5926 Follow these rules and everything works fine.
5928 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added new function silc_server_remove_clients_by_server to
5931 remove all client entries from ID list when the server connection
5932 is lost. In this case it is also important to invalidate all
5933 client entires as they hold the invalid server entry. This
5934 fixes fatal bug when server has lost connection and will reconnect
5937 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Made some sanity checks to silc_server_daemonise like to check
5940 whether the requested user and group actually exists.
5942 * Added sanity check to SKE's silc_ske_responder_finish to check
5943 that the public and private key actually is valid.
5945 * Invalidate the client's nickname when receiving Replace ID
5946 packet and the Client ID is being replaced. This means that the
5947 server will query the nickname if someone needs it (client)
5950 * Sort the ID Cache in client library when the ID Cache data
5951 has changed (needs sorting).
5953 * Do not allow for SILC client to create several connections to
5954 several servers. The client does not support windows right now
5955 and generating multiple connections causes weird behaviour.
5957 Irssi-silc client does support windows and can handle several
5958 connections without problems, see: www.irssi.org and SILC plugin.
5960 * Fixed some places where client was added to the IDList. The
5961 rule of thumb is following (in order to get everything right):
5962 If the client is directly connected local client then the
5963 `connection' argument must be set and `router' argument must be
5964 NULL to silc_idlist_add_client function. If the client is not
5965 directly connected client then the `router' argument must
5966 bet set and the `connection' argument must be NULL to the
5967 silc_idlist_add_client function.
5969 * The funtion silc_server_packet_send_local_channel actually did
5970 not check whether the client was locally connected or not. It
5971 does that now. Fixed a bug related to LEAVE command.
5973 * Fixed Remove Channel User payload parsing bug in server's
5974 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5976 * The server's silc_server_save_channel_key now checks also the
5977 global ID list for the channel as it might not be in the local
5978 list. Fixed a bug related to LEAVE command.
5980 * Is this the end of the [<unknown>] buglet that has been lurking
5981 around for a long time? A little for loop fix in server's
5982 silc_server_command_whois_parse that is used by both IDENTIFY
5983 and WHOIS command. At least, this was a clear bug and a cause
5984 of one type of [<unknown>] buglet.
5986 * WHOIS and IDENTIFY commands call the function
5987 silc_server_command_[whois/identify]_check function even if
5988 we are not router server.
5990 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Added --with-gmp configuration option. If set the GMP
5993 is always compiled in the SILC source tree. If not set then
5994 it is checked whether the system has the GMP3 installed. If
5995 it has then the GMP won't be compiled (the system's headers
5996 and library is used), if it doesn't have it then the GMP is
5997 compiled in the SILC source tree.
5999 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Changed RSA private exponent generation to what PKCS #1
6002 suggests. We try to find the smallest possible d by doing
6003 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6004 not security fix but optimization.
6006 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added new config entry [Identity] to fork the server and run
6009 it as specific user and group. A patch from Bostik.
6011 * Imported Dotconf configuration library into lib/dotconf.
6012 This will be used to create the SILC configuration files later.
6013 It will appear in the distsribution after this commit.
6015 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * A big code auditing weekend happening. Auditing code for
6018 obvious mistakes, bugs and errors. Also, removing any code
6021 Removed files for being obsolete:
6023 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6024 inline in the file lib/silcutil/silcbuffer.h)
6026 o lib/silcutil/silcbufutil.c (the header has inline versions)
6028 Changed code to fix possible error conditions:
6030 o The buffer formatting routines now check that the destination
6031 buffer really has enough space to add the data. This applies for
6032 both buffer formatting and unformatting
6033 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6034 unformatting was changed to accomodate following rules:
6035 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6036 sent to the function while XXX_*STRING will not allocate or copy
6037 the data into the buffer. Instead it sets the pointer from the
6038 buffer into the pointer sent as argument (XXX_*STRING used to
6039 require that the pointer must be allocated already). This change
6040 makes this whole thing a bit more consistent and more optimized
6041 (note that the data returned in the unformatting with XXX_*STRING
6042 must not be freed now). The routines return now -1 on error.
6044 o Tried to find all code that use buffer_format and buffer_unformat
6045 and added return value checking to prevent formatting and
6046 especially unformatting errors and possible subsequent fatal
6049 o Changed ske->x and ske->KEY to mallocated pointers in
6050 lib/silcske/silcske.h. Fixed possible data and memory leak.
6052 o Added return value checking to all *_parse* functions. Fixed
6053 many memory leaks as well.
6055 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6056 so that buffer overflows would not happen. All code now also
6057 checks the return value as it can fail.
6059 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Added reconnection support to server if the normal server looses
6062 its connection to the router (for example if router is rebooted).
6063 The server performs normal reconnection strategy implemented
6064 to the server. Affected file silcd/server.c.
6066 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Added new packet type SILC_PACKET_SET_MODE that is used to
6069 distribute the information about changed modes (for clients,
6070 channels and clients channel modes) to all routers in the
6071 network. Updated the protocol specification accordingly.
6073 Added functions into silcd/packet_send.c and
6074 silcd/packet_receive.c: silc_server_send_set_mode,
6075 silc_server_set_mode.
6077 Added new files silcmode.[ch] into lib/silccore that implements
6078 the encoding and decoding of Set Mode Payload. Added new type
6079 SilcSetModePayload. Moved the definitions of different modes
6080 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6082 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Oops, a little mistake in server's connection authentication
6085 protocol. The protocol is not ended with FAILURE but with
6086 SUCCESS if the authentication is Ok. :) Affected file is
6089 * Implemented NICK_CHANGE notify handling in server in the file
6090 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6091 the local clients on the channel. After the changing nickname
6092 in router environment snhould work and the [<unknown>] nickname
6093 should appear no more.
6095 The silc_server_replace_id function that receives the Replace ID
6096 payload now sends the NICK_CHANGE notify type also in the file
6097 silcd/packet_receive.c
6099 * Changed WHOIS and IDENTIFY command to support the maximum amount
6100 of arguments defined in protocol specs (3328 arguments). This
6101 fixed a bug that caused problems when there were more than three
6104 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Added extra parameter, command identifier, to the
6107 silc_client_send_command so that explicit command identifier
6110 Changed that ID list routines uses specific command identifier
6111 when sending WHOIS/IDENTIFY requests to the server so that they
6112 can be identified when the reply comes back.
6114 Affected files lib/silcclient/command.[ch],
6115 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6117 * Added `sender' argument to silc_server_packet_send_to_channel
6118 to indicaet the sender who originally sent the packet to us
6119 that we are now re-sending. Ignored if NULL. Affected file
6120 silcd/packet_send.[ch].
6122 * Added some server statistics support in silcd/server_internal.h
6123 SilcServerStatistics structure and around the server code. Also
6124 send some nice statistics information when client is connecting
6127 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Fixed channel ID decoding in server's JOIN command reply in
6130 silcd/command_reply.c
6132 * Fixed braodcasting of replace ID payload to not to send it if
6133 we are standalone server in silcd/packet_receive.c.
6135 * Fixed all channel message sending routines to not to send
6136 packets to clients that has router set, since they are routed
6137 separately in the same function earlier. Affects file
6138 silcd/packet_send.c and all channel packet sending functions.
6140 * In USERS reply, res_argv[i] are not allocated, the table
6141 is allocated. Thus changed that free the table, not its
6144 * In server's whois_check and identify_check if the client is
6145 locally connected do not send any WHOIS commands - they are not
6148 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Fixed some minor bugs in client when sending WHOIS command. The
6151 arguments was in wrong order.
6153 * Removed statis function add_to_channel from server in
6154 silcd/command.c that was previously used with the joining but
6157 * Tested USERS command in router environment successfully with two
6158 routers, two servers and two clients.
6160 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Reorganized the USERS command and command reply in client library
6163 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6164 When the command is given by user we register a pending command
6165 callback that will reprocess the command after the reply has been
6166 received from the server. When reprocessing the packet we then
6167 display the information. Thus, the USERS information is displayed
6168 now in the command callback instead of in the command reply
6169 callback. The processing of the command is same as previously
6170 when server has sent the command reply in the JOINing process.
6172 * Added to USERS command in silcd/command_reply.c to join the client,
6173 we didn't use to know about, to the channel after we've created
6174 a client entry for it. Also, for clienet we did know already still
6175 check whether it is on the channel or not and add it if not.
6177 * Removed silc_server_command_join_notify as the function and its
6180 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Changed the client's pending command handling to the same as the
6183 server's pending command handling. It is also now possible to
6184 execute command reply functions from other command reply
6185 function as the function callbacks for commands and command
6186 replies are one and same. The pending commands are not static
6187 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6188 in client connection context. Thus, pending commands are server
6189 connection specific as it is convenient.
6191 Changed the function silc_client_command_pending and
6192 silc_client_command_pending_del and added new function
6193 silc_client_command_pending_check. Removed the
6194 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6197 * Added cmd_ident, current command identifier, to the client
6198 connection context in lib/silcclient/client.h to keep track on
6199 command identifiers used in command sending. Client's command reply
6200 function handling now supports the mandatory command identifiers.
6202 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6203 funtions in client to fully support pending command callbacks.
6205 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6206 as one of the arguments to the application in the command reply
6209 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6210 before first releasing SILC but came back. Now it is removed again
6211 and should come back nomore. The FORWARDED flag was used only
6212 by the JOINing procedure by forwarding the command packet to router.
6213 Now, the JOINing procedure has been changed to more generic (due
6214 to various router environment issues) and FORWARDED is not needed
6215 anymore for anything. The protocol specification is yet to be
6218 Now, removed silc_server_packet_forward from server and the flag
6219 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6221 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Renamed NAMES command to USERS command. The NAMES was named that
6224 due to historical reasons. Now it is renamed. Also, rewrote
6225 parts of the USERS command. The nickname list is not sent anymore
6226 by the server. Only Client ID and mode lists are sent in the USERS
6227 command. Changed this also to the protocol specification.
6229 The client now resolves the names and stuff after it receives
6230 the USERS list from the server when joining to the channel.
6232 * WHOIS and IDENTIFY commands has been changed to support multiple
6233 Client ID's per command. One can now search for multiple users
6234 in the network by sending only one WHOIS or IDENTIFY command.
6235 Changed the code and the protocol specifications.
6237 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6238 uses silc_server_command_whois_parse to parse the request. */
6240 * If normal server, do not parse the WHOIS and IDENTIFY requests
6241 before sending it to the router. Saves some time.
6243 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6245 * Fixed JOIN command on client library. Wrong number of arguments
6246 used to crash the client.
6248 * Added silc_server_channel_has_global function to check whether
6249 channel has global users or not.
6251 * Added silc_server_channel_has_local function to check whether channel
6252 has locally connected clients on the channel.
6254 * The silc_server_remove_from_one_channel now checks whether the
6255 channel has global users or not after given client was removed from
6256 the channel. It also checks whether the channel has local clients
6257 on the channel anymore. If it does not have then the channel entry
6258 is removed as it is not needed anymore.
6260 * The silc_server_notify now checks on JOIN notify whether the joining
6261 client is one of locally connected or global. If it is global then
6262 the channel has now global users on the channel and that is marked
6263 to the channel entry. Also, it now saves the global client to
6264 global list who is joining and JOINs it to the channel. This is
6265 for normal server, that is.
6267 Changed silc_server_send_notify_on_channel,
6268 silc_server_packet_relay_to_channel and
6269 silc_server_packet_send_to_channel check if we are normal server
6270 and client has router set (ie. global client) do not send the
6271 message to that client, as it is already routed to our router.
6273 * Implemented LEAVE notify type handling in silc_server_notify
6276 * Tested LEAVE command in router environment successfully. Tested
6277 with two routers, two servers and two clients.
6281 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6283 * Implemented SIGNOFF notify type handling in silc_server_notify
6286 * silc_server_remove_id now removes the client entry from all channels
6287 it has joined and thusly sends SIGNOFF notify type.
6289 * Rewrote the NAMES list generation in server by removing two excess
6290 loops. The lists are created now inside one loop.
6292 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * silc_server_remove_channel_user checks now also global list
6295 for channel and client.
6297 * silc_server_new_channel_user checks now both local and global
6298 list for channel and client. Fixed a bug in client id decoding.
6299 Used to decode wrong buffer.
6301 * silc_server_channel_message checks now both local and global
6302 list for channel entry.
6304 * Tested channel joining (hence JOIN) in router environment
6305 successfully. Tested with two routers, two servers and two
6308 * Tested channel message sending in router environment successfully.
6310 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Added silc_server_save_channel_key into server.[ch] to save the
6313 received channel key in Channel Key payload processing. It is
6314 also used in JOIN command reply handling.
6316 Equivalent function silc_client_save_channel_key added into
6317 client.[ch] into client library.
6319 * Changed JOIN command reply to send information whether the channel
6320 was created or not (is existing already) and the channel key
6321 payload. Changed protocol specs accordingly.
6323 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6324 the request was sent by ID and not by nickname. Crashed on
6327 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6330 now correctly save the received data.
6332 * silc_server_free_sock_user_data now notifies routers in the
6333 network about entities leaving the network.
6335 At the same time implemented functions silc_server_remove_id
6336 and silc_server_send_remove_id to receive and send REMOVE_ID
6337 packets. The packet is used to notify routers in the network
6338 about leaving entities. The ID removed will become invalid in
6341 * Added function silc_idlist_del_server into server. Removes and
6342 free's server entry from ID list.
6344 * silc_server_private_message function now checks, if we are router,
6345 that the destination ID really is valid ID, naturally.
6347 * In router when NEW_ID packet is received (for new client) the
6348 hash of the Client ID is saved in the ID Cache but the
6349 client->nickname is set to NULL, instead of putting the hash
6352 IDENTIFY command now also checks that client->nickname must be
6353 valid. If it is not if will request the data from the server who
6354 owns the client. Added new function
6355 silc_server_command_identify_check.
6357 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6358 to set the command to already allocated Command Payload.
6360 * Tested private message sending in router environment with two
6361 routers, two servers and two clients. Fixed minor bugs and now
6364 * Fixed segfault from client's NAMES command. Used to crash if
6367 * Forwarded packets must not be routed even if it is not destined
6368 to the receiver. Changed server code comply with this.
6370 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added `require_reverse_mapping' boolean value to ServerParams
6373 structure. If TRUE (not default) the server will require that
6374 the connecting host has fully qualified domain name.
6376 If the reverse mapping is not required and hostname could not be
6377 found the IP address is used as hostname.
6379 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6381 * Implemented version string checking to both client and server.
6382 The check is incomplete currently due to the abnormal version
6383 strings used in development version of SILC.
6385 * Changed all command functions in server to use the new
6388 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Changed char *data to unsigned char *data in ID Cache system to
6391 support binary data as ID Cache data. Changed code to support
6392 binary data in lib/silccore/idcache.c.
6394 * Renamed silc_server_packet_relay_command_reply to
6395 silc_server_command_reply as it is normal packet receiving
6396 function. Rewrote the function to accept command replys for
6397 servers and not only for clients.
6399 * Mark remote router always as registered server if we are connecting
6400 to it. Otherwise, commands sent by the router to us are ignored.
6402 * All ID List find routines now returns the ID Cache Entry pointer
6403 as well if requested.
6405 * WHOIS command works now in router environment, tested with two
6406 routers, two servers and two clients.
6408 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6409 in router environment (as it is almost equivalent to WHOIS) but
6410 hasn't been tested thoroughly. Added new functions:
6412 silc_server_command_identify_parse
6413 silc_server_command_identify_send_reply
6414 silc_server_command_identify_from_client
6415 silc_server_command_identify_from_server
6417 * Disabled route cache adding because adding two different ID's with
6418 same IP replaces the old cache entry thus giving wrong route.
6419 The entry->router->connection is always the fastest route anyway
6420 so route cache may not be needed. Of course, new routes maybe
6421 established after receiving the ID when the entry->router->connection
6422 might not be anymore the most optimal.
6424 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Add route cache for received ID for fast routing.
6428 * Added silc_server_packet_route to route received packet on router
6429 that is not destined to us.
6431 * Renamed silc_server_get_route to silc_server_route_get.
6433 * Added id_string and id_string_len fields into SilcServer to
6434 include encoded ServerID for fast comparing without excess
6435 encoding of the ID's.
6437 * Cleaned up WHOIS command on server side. Added following static
6440 silc_server_command_whois_parse
6441 silc_server_command_whois_check
6442 silc_server_command_whois_send_reply
6443 silc_server_command_whois_from_client
6444 silc_server_command_whois_from_server
6446 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6447 arguments in command replies. All command functions should be
6448 updated to use this macro.
6450 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Minor typo fixes on command reply handling on server.
6454 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Added silc_server_command_add_to_channel internal routine to add
6457 the client to the channel after router has created the channel and
6458 sent command reply to the server.
6460 * Added generic silc_server_send_command to send any command from
6463 * Use static buffer with ID rendering instead of duplicating data.
6465 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Fixed a channel user mode bug when joining to a channel server gave
6468 everybody channel founder rights, oops.
6470 * We mark ourselves as the router of the incoming server connection
6471 if we are router ourselves. This way we can check in some packet
6472 sending functions whether it is locally connected server. For
6473 incoming router connections we put NULL.
6475 * For router sending packets locally means now always sending the
6476 packet cell wide; to local clients and local servers. For normal
6477 server sending packet locally means sending it to only local
6480 * Fixed the JOIN command to really work in router environment. If the
6481 channel is created it is always created by the router. Router is
6482 also responsible of making the initial joining to the channel,
6483 sending JOIN notify to the sending server and distributing
6484 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6485 does not exist server doesn't do anything else but forward the
6486 command to the router which performs everything.
6488 * Added silc_server_send_channel_key function to send the Channel Key
6491 * Added silc_server_create_channel_key to create new channel key. The
6492 channel key is now re-generated everytime someone joins or leaves
6493 a channel, as protocol dictates. Note: channel->key_len is the
6496 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6499 packet_receive.[ch] to separate packet sending and receiving
6500 routines. The server.[ch] now includes everything else including
6501 actual packet processing (writing and reading data) and other
6504 Renamed silc_server_private_message_send_internal to
6505 silc_server_send_private_message. The routine is still though
6506 used only to relay private messages as server does not send
6507 private messages itself.
6509 Renamed silc_server_new_channel to silc_server_create_new_channel
6510 and added new function sicl_server_new_channel that handles the
6511 incoming New Channel packet. Added also new sending function
6512 silc_server_send_new_channel to send New Channel Payload.
6514 * Added new function silc_server_notify to process incoming notify
6515 packet to the server/router. Server may then relay the notify
6516 to clients if needed.
6518 * Added new function silc_server_new_channel_user to process incoming
6519 New Channel User packet. Router will redistribute the packet and
6520 send JOIN notify to its local clients and locally connected servers
6521 if needed. Normal server will send JOIN notify to its local client
6522 on same channel when received this packet. Added also corresponding
6523 sending function silc_server_send_new_channel_user to sent the
6526 * Added boolean route argument to send_notif_to_channel and
6527 packet_send_to_channel functions to attempt to route the packet
6528 if it is TRUE and send only locally if it is FALSE.
6530 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * silc_server_replace_id now broadcasts the received replace ID
6533 packet if it is not broadcast packet already. The router must
6534 broadcast to inform other routers about changed ID.
6536 * Added backpointer to server's router into SilcServer context in
6537 silcd/server_internal.h.
6539 * Fixed silc_server_packet_broadcast to send correct broadcast
6542 * The channel key is now distributed to the local client as soon
6543 as it is received from the router (in router environment) so that
6544 no other packet may be sent for the channel until client has
6547 * silc_server_remove_channel_user now broadcasts the received
6548 Remove Channel User packet if it is not broadcast packet already.
6549 The router must broadcast to inform other routers about removed
6552 * Added users field into SilcPacketContext that is a reference count
6553 of the context. One can increase the reference count by calling
6554 silc_packet_context_dup which is now changed to just increase the
6555 reference count instead of duplicating the data. The reference
6556 count is decresed by calling silc_packet_context_free that will
6557 free the data after the reference count hits zero.
6559 For now on the packet context and everything allocated into it
6560 (including the raw packet from network) must be freed by calling
6561 the new silc_packet_context_free function. Added also new function
6562 silc_packet_context_alloc that must be used now to allocate the
6563 context. This also means that if a routine is asynchronous from
6564 silc_[client/server]_packet_parse_type the packet context must
6565 be duplicated by calling silc_packet_context_dup. Otherwise it
6566 gets free'd after silc_[client/server]_packet_parse_type returns.
6567 Also, one must remember that if packet is duplicated then its
6568 reference count must be decresed by calling the free function as
6569 many times as it was duplicated.
6571 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6572 from both client and server.
6574 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Made joining to a channel working in router environment.
6578 * Cleaned up JOIN command on server side and create function
6579 silc_server_command_join_channel internal routine to make the
6582 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Changed silc_command_pending list to SilcDList. Also, added
6585 `ident' field to SilcServerCommandPending structure to identify
6586 the reply and to call correct callback.
6588 Added silc_server_command_pending_check function to replace the
6589 corresnponding macro. The silc_command_pending list is not
6592 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6593 to set identifier to previously allocated Command Payload. It
6594 is used to set identifier for command when resending Command
6597 * Added silc_command_payload_encode_payload to encode Command
6598 Payload buffer from SilcCommandPayload structure.
6600 * Added silc_argument_payload_encode_payload to encode Argument
6601 payload buffer from SilcArgumentPayload structure.
6603 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Changed WHOIS command to support router connection on server side.
6606 The whois request is always sent to router unless the server is
6607 standalone server. After server has received the reply from the
6608 router will it send the reply to the client.
6610 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6611 broadcast received broadcast packet. The function is used only
6612 by router. The broadcast packet is always sent to the router's
6615 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6616 render given ID to printable string, for log files for example.
6618 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Made basic router to router connections working. At least they
6621 can now connect to each other but nothing really works the way
6622 they are supposed - yet.
6624 * Added new initiator token to RouterConnection configuration
6625 file in silcd/serverconfig.[ch]. It is used to tell whether we
6626 are the initiator to the remote router or whether we'll expect
6627 the other end to connect.
6629 * Moved registering of listener task to silc_server_init, hence
6630 the server starts listenning as soon as it is run, even if it
6631 does not have connections to other routers. Let's see how well
6634 * Changed default connection retry timeouts for more suitable in
6637 * Removed cipher and such arguments from silc_idlist_add_client
6638 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6639 Added new function silc_idlist_add_data to add the keys and stuff
6642 * Added SilcIDListData structure and added it to SilcClientEntry
6643 and SilcServerEntry as their first field in the structure. This
6644 way we can explicitly cast the ID entries to the SilcIDListData
6645 structure and get common data for the entries. In past, we had
6646 to first check what type of connection it is and then cast it to
6647 correct ID entry type. Now, we can directly cast the opaque
6648 pointer to the SilcIDListData (no matter what ID entry it actually
6649 is) and get the data needed.
6651 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6654 in some circumstances even if threre were timeout tasks, though not
6655 IO tasks, but tasks anyway. Now fixed.
6657 * Defined SilcServerConnection structure to hold connection specific
6658 stuff about directly connected servers and routers. The definition
6659 is currently in silcd/server_internal.h. I thought about having
6660 a bit more important role fro this struct but for now it is used
6661 only when connecting to other server (or router actually).
6663 * Added connecting retry support in server when connecting to
6664 router(s). The retry feature implement exponential backoff
6665 algorithm. Also, added SilcServerParams structure to hold default
6666 parameters for server. For now, it include these retry settings
6667 and are hard coded. After server is moded to be as Silc Server
6668 Library this structure will be more important.
6670 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * Changed client librarys channel->clients table to SilcList and
6673 changed code accordingly.
6675 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6677 * Changed client's channel table to SilcList and changed code
6678 accordingly. Also changed SilcChannelClientEntry to include back-
6679 pointer to the channel so that client entry can use that structure
6680 as list as well and we have fast cross-reference to the channel.
6681 This change dramatically decreased the complexity of channel
6682 handling with client entry and vice versa (removed one extra
6683 loop when searching for channel entry from many functions).
6685 * Changed server->sim from table to SilcDList and changed code
6688 * NAMES command can now be used from user interface. It will show
6689 the user list on the channel, neatly.
6691 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6692 Code now saves realname of the user if it becomes available.
6694 * Renamed configure.in to configure.in.pre and made ./prepare
6695 script to automatically add correct version string to
6696 configure.in which it creates from configure.in.pre.
6698 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * NAMES command reply now shows users mode with the nickname when
6703 * Moved silc_client_ch[u]mode[_char] functions from
6704 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6705 place sucks, they are utility functions and should be in some
6708 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6710 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6713 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Added TRQ (efficient deque and list library) into lib/trq. This is
6718 a very good list library that is currently used in the SILC. Defined
6719 SilcList API over the library because I didn't like the API very
6720 much. See lib/trq/silclist.h for the API and examples of how to
6721 use the API. Fixed various places in the code to use the new
6722 SilcList API. The SilcList is meant for lists that has a structure
6723 already defined as a list. It is not suitable to add just some
6724 context to the list (in TRQ, the context is the list actually).
6726 So, I defined SilcDList that can be used for the purpose where
6727 predefined list structure does not exit. This can be used as
6728 such list. Now some context just can be added to the SilcDList.
6729 Currently this list is not used in the SILC just yet, though there
6730 are a lot places where this can replace dynamically allocated
6731 tables and I will fix these places, later, to use SilcDList.
6732 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6733 and use TRQ internally).
6735 Also fixed some annoying warning messages that the original TRQ
6736 code generated. Also minor changes to TRQ's Makefile.in.
6738 * Added support for querying by Client ID to both WHOIS and
6739 IDENTIFY commands into server, as required by the protocol.
6741 * Removed method function pointers from SilcBuffer structure. They
6742 weren't used to anything and just increased the context size for
6743 no good reason. This change also made silc_buffer_alloc and
6744 silc_buffer_free functions inline functions.
6746 * Disabled command flooding detection support until it's fixed so
6747 that it accepts commands in but does not execute them more than once
6750 * Added silc_net_localhost(), to return local hostname, into
6751 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6752 that must be initialized before calling silc_client_init.
6754 * Added new function: silc_server_send_notify_on_channels to send
6755 notify messages to all channels client has joined. It is assured
6756 that the message is sent only once per client.
6758 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6759 lib/silcutil/silcutil.[ch] as silc_format function. The new
6760 function is generic and is used by server as well, not only by
6761 the logging routines.
6763 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6764 the provided version string was not acceptable. Added new function:
6765 silc_ske_check_version into lib/silcske/silcske.h. The function
6766 must be implemented by the application (client or server) and it
6767 does not reside in the SKE library. The function checks the version
6768 string remote end sent.
6770 * Added back pointers (to opaque context and to SilcSocketConnection)
6771 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6773 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6774 duplicate packet context structure.
6776 * Changed `notify' client operation to send same arguments as client
6777 receives from server except for ID's. ID's are mapped to correct
6778 ID entry and that is returned. Also, if channel entry is not sent
6779 by server but the notify is for channel the channel entry is sent
6780 to application (otherwise application doesn't know that it is for
6781 channel (library gets it from packet's Destination ID)).
6783 * Added silc_client_remove_from_channels into client library to
6784 remove a client from all channels it has joined to. Used when
6785 received SIGNOFF notify from server. Added also new function
6786 silc_client_replace_from_channels to replace old ID entry with
6787 new ID entry on all channels. Used when received NICK_CHANGE
6790 * Fixed ID Cache list handling in silc_idlist_get_client in
6791 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6792 to get (or query) client by ID.
6794 * Updated TODO list.
6796 * Added connection authentication status message defined by the
6797 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6798 support for these into the code in client and server side.
6800 * Added generic function silc_client_send_command to send any command
6801 with variable argument list. Application should use this function
6802 to send commands if the command functions provided by the library
6803 does not suite for the application's user interface needs.
6805 * Added new `failure' client operation. Application is notified about
6806 received failure packet if client is executing a protocol. In this
6807 case the protocol's execution has failed.
6809 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6810 is required by the protocol.
6812 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6813 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6816 * Added status flag to SilcSKE object to indicate realtime status
6817 of the SKE protocol.
6819 * Application receives now exactly same command reply arguments as
6820 the library receives from server. However, if ID is received the
6821 corresponding ID entry is returned to the application (eg. Client
6822 ID is mapped to correct SilcClientEntry entry and that is returned).
6823 Changed command_reply client operation due to this change.
6825 * Changed all ID's in commands and in command replys as ID Payloads.
6826 Change affected both client and server side codes.
6828 All ID's sent in SILC network (with execption of ID's in SILC
6829 Packet header) are sent in ID Payload to support variable length
6832 * Server now notifies nick changes and notifies all clients on
6833 the channels about the new nickname (about the new Client ID,
6836 * Implemented CMODE command to change channel modes. Supports all
6837 channel modes defined by the protocol specs except ban and invite
6838 lists. (Also, private channel key mode is supported but support for
6839 setting private channel key in client is missing, thus, this mode
6840 has no effect on client side (except that server requires that the
6841 client uses private channel key and normal channel traffic does not
6844 Also, invite mode works per se, but INVITE command does not work
6845 yet correctly, so you can set channel as invite only channel but
6846 inviting clients to the channel does not work (it is yet to be
6847 thought what's the best way to do it).
6849 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6850 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6851 Implemented CUMODE command to change user's mode on the channel.
6852 Supports all modes defined by the protocol specs.
6854 * Added NAMES command reply to return users modes on the channel.
6856 * Removed unnecessary and slow ciphers from lib/silccrypt.
6858 * Set SO_KEEPALIVE option to connection sockets by default.
6860 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6862 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6863 redefined the Notify Payload into protocol specs.
6865 * Added silc_id_payload_parse_id to get ID directly from raw
6868 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6871 accept searching by Client ID as well.
6873 * Added support for LEAVE and SIGNOFF notify types in client library.
6875 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6876 to parse ID Payload from raw data.
6878 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Added flags parameter into silc_ske_assemble_security_properties
6881 function in lib/silcske/silcske.[ch].
6883 * Changed notify client operation to fit better for notify messages
6884 sent by server. The notify payload received from server is now
6885 passed to the application (after parsing it to SilcNotifyPayload).
6886 It is application's responsibility to retrieve the arguments
6887 from the payload and show the message the way it wants. The message
6888 sent by server is implementation specific.
6890 * Changed public keys to comply with the protocol specification.
6891 Old public keys are not supported anymore and are not compatible.
6893 * Removed nickname from Channel Payload as the latest draft removed
6894 it. The client must resolve the nickname from the NAMES command
6895 reply received when it joined the channel.
6897 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6899 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Fixed some errors in protocol specification drafts.
6903 * Created lib/silccore/silcnotify.c to implement Notify Payload
6904 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6905 generic payloads described by protocol specifications. The file
6906 includes implementations for ID Payload and Argument Payload.
6908 * Changed Command Payload implementation to use the new Argument
6909 Payload. Changed command_xxxx_payload to command_payload_xxxx
6910 to comply with SILC coding conventions.
6912 * Added suppport for Argument Payload handling in Notify Payload
6913 implementation as protocol requires it. Added the new support
6914 into server and client lib as well.
6916 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Added support for multiple nicknames on same channel. [n] is
6919 added locally to the nickname if there are more than one same
6920 nicknames on the channel.
6922 * Server now sends all nicknames that matched WHOIS request.
6923 Client also shows the list received from server.
6925 * Added TOPIC command to client side. User can now set and show
6926 current topic on channel.
6928 * Added MOTD command to client and server. Also, server sends the
6929 motd when client connects to the server.
6931 * Changed version strings to comply ISO 8601.
6933 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Fixed protocol error handling in client library. It should now
6936 cope even if the SKE fails for some reason.
6938 * Made new protocol specification drafts for submitting to IETF.
6940 * Implemented TOPIC command to server in silcd/command.c.
6942 * Added two new notify types into lib/silccore/silcnotify.h:
6943 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6944 notify nickname change and topic setting/change on a channel.
6946 * API change of command_reply operation in client library. The
6947 application gets now the status type received from server as well.
6949 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6951 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6953 * Cras fixed and optimized the packet handling even further and
6954 it should work now. Minor change to the prototype of function
6955 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6957 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Added new function into lib/silcutil/silcschedule.[ch]:
6960 silc_schedule_with_fd to select() a specified fd. The function
6961 returns after timeout expires or data arrives or goes. The
6962 function is used by packet routines to wait that all data is
6963 received from network.
6965 * Fixed data reading from network in lib/silccore/silcpacket.c.
6966 The code now assures that all data is read from the fd and then
6967 continues packet processing. This was a bug fix since the code
6968 used to drop some data in some circumstances.
6970 * Added new function into lib/silcclient/client.[ch]:
6971 silc_client_start_key_exchange to start key exchange after
6972 connection has been established to server. The code internally
6973 now uses this funtion but its main purpose was to provide it
6974 for applications that perform their own connecting. After
6975 application has created a connection it merely calls this
6976 function to start the key exchange between client and server.
6977 The library takes care of everything else after that.
6979 Updated also lib/silcclient/README to explain the usage of
6982 * Do not send to application information that connection has
6983 been established. Application gets notified it by connect
6986 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Applied cras's patch to add silc_schedule_one function. The
6989 function runs scheduler once and returns.
6991 * Fixed the scheduler after cras messed it up. The timeout
6992 handling works now as it's supposed to work.
6994 * Added into lib/silccore/ silcnotify.h to include notify
6995 message types support. Changed silc_server_send_notify*
6996 functions, in server.[ch], to support those new notify types.
6997 Added the support for the notify types into client library,
6998 as well. Added new notify client operation into ops.h in
7001 * Changed silc_server_packet_send_to_channel to send normal
7002 packets instead of just channel message packets. The function
7003 is now used to send the notify packets to channels. It is not
7004 used to send channel message packets anymore, as server never
7007 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7008 va_arg()s as it seems to require it nowadays. I guess, if SILC
7009 is compiled with older va_arg() the new code should work anyway.
7011 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Splitted core library. Core library (lib/silccore) includes
7014 now only SILC protocol specific core (and common) components.
7015 Created new utility library (lib/silcutil) that includes more
7016 generic purpose stuff. The stuff for util library was taken
7017 from the old core library. This was minor and easy split.
7019 * Created SILC Client Library (lib/silcclient) that includes
7020 implementation of the SILC client without user interface. This
7021 was major move from silc/ directory. The code has been changed
7022 so that it is transparent towards the user interface. The
7023 silc/ directory includes now the same user interface as before
7024 and it uses the new client library. Read lib/silcclient/README.
7025 Basicly, the client library performs everything else related
7026 to SILC except user interface handling. Also, configuration
7027 files are considered to be part of user interface and library
7028 does not handle them.
7030 This change also changed a lot of structures, function naming etc.
7031 Most important change was that SilcClientWindow object was
7032 renamed to SilcClientConnection in the client library. Created
7033 also new file lib/silcclient/ops.h. Also added new files
7034 silc/local_command.[ch] and silc/client_ops.[ch].
7036 All these changes were made to make it easier for user interface
7037 designers to create what ever user interface for the SILC client
7040 It is also expected that the server will be moved to lib
7041 directory as well and SILC Server Library will be created;
7042 sometimes in the future.
7044 * Removed Local commands from lib/silccore/silccommand.h as
7045 they are application specific and new client library does not
7046 handle any of those anymore.
7048 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7049 old client implementation in silc/.
7051 * Added support for callback functions in SILC_LOG_* macros.
7052 Application can now set its own callbacks that will be called
7053 instead of using the default functions that will always print
7054 the debug messages to stderr (or stdout). Also, debugging can
7055 now be disabled by setting silc_debug to FALSE and re-enabled by
7056 setting it to TRUE. Note, that logging will still work even
7057 if debugging is disabled.
7059 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7060 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7061 silc_log_reset_debug_callbacks.
7063 * To enable debugging in silc client one must give now -d
7064 option on command line.
7066 * Changed silc_schedule_init to automatically allocate task queues
7067 if they are not allocated before calling it.
7069 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Added GMP 3.1 into math library.
7073 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7076 a channel in SILC network. The packet is used by servers and
7077 routers to notify other routers that user has left a channel.
7078 This little feature was missing until now. Added the feature
7079 to protocol specification as well.
7081 Added functions: silc_server_send_remove_channel_user and
7082 silc_server_remove_channel_user into server.[ch].
7084 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7085 lib/silccore/silcpacket.h. However, they are not implemented
7088 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Fixed joining to a channel and sending channel messages
7091 between server and router. The channel message sending should
7092 now work inside a cell.
7094 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Fixed the private message sending between server and router.
7097 The private message sending should now work inside a cell.
7099 * Added silc_server_replace_id into server.[ch] to replace
7100 existing ID in the SILC network.
7102 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7103 and silc_idlist_replace_server_id into idlist.[ch] in server.
7105 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * Fixed the server to server connections. Server can again now
7108 connect to router. Router to router connections probably does
7111 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * Added dynamic protocol registering support. Now protocols can
7114 registered and unregistered on the fly. Patch by cras.
7116 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Added lib/contrib directory to hold routines that some platforms
7119 don't have but are needed by SILC.
7121 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7122 into lin/contrib to provide getopt() and getopt_long() for
7123 those who don't have it.
7125 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Added AWAY command to client. When away message is set and
7128 client receives a private message packet the client automatically
7129 replies to the sender with the away message.
7131 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7132 bug seemed to be the cause of recent problems when compiling
7135 * Added version detection support to SKE protocol specification
7136 and added the new changes to the SKE implementation as well.
7137 There were other minor changes in the SKE protocol as well.
7139 Many changes in lib/silcske/silcske.[ch] and in
7140 lib/silcske/payload.[ch].
7142 * Added ^U functionality, clear input line. Patch from cras.
7144 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Mainly small bugfixes on core library. Fixed some debugging
7147 logging and buffer overflow in silclog.c.
7149 * Updated config.sub and config.guess on the distribution tree.
7151 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Added command lagging support in server. Client may execute
7154 commands now only once in two seconds.
7156 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Optimized packet reception. MAC computation and checking is now
7159 also more optimized. A lot previously duplicated code is now
7160 used as generic by both client and server.
7162 * Fixed key pair generation in clientutil.c
7164 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Added into lib/silccore/silcbufutil.[ch] new function;
7167 silc_buffer_realloc.
7169 * Moved generic packet sending/encryption functions to
7170 lib/silccore/silcpacket.[ch] from client and server. Some
7171 rewriting of the functions.
7173 * Moved all generic packet reception/decryption functions to
7174 lib/silccore/silcpacket.[ch] from client and server. The
7175 packet processing is now much cleaner in both client and server.
7176 These were major changes in both client and server.
7178 * Created many common functions in server to do packet sending.
7179 Previously code were duplicated a lot, this has been removed
7182 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7184 * Rewrote major parts of the ID cache system. Don't know
7185 whether it is better now or not but at least the API is more
7188 * Major rewrite on ID cache stuff on client because of the ID
7189 cache API changes. Added idlist.c to client.
7191 * Also major rewrite on ID cache stuff on server as well.
7192 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7193 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7194 in hand, instead they are all put into the ID cache system now.
7195 All server_idlist_* routines uses ID cache now instead of
7196 traversing its own lists (those lists does not exist anymore).
7197 SilcIDList though still exists. Also, SilcXXXEntry's are
7200 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Finally made the SKE implementation compliant to the protocol
7203 specification. All mp integers are now binary encoded as
7204 opposed being HEX encoded.
7206 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7209 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7210 functions: silc_[encode/decode]_pem. Also added function
7211 silc_encode_pem_file to PEM encode with newlines ('\n') for
7214 * SILC public keys are now encoded either PEM or binary. Same
7215 option is for private keys as well. By default private keys
7216 are binary encoded and public keys PEM encoded. Silly HEX
7217 encoding were removed.
7219 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7220 function to create fingerprints.
7222 * Fixed a bug in SHA1; does not change the original data anymore.
7224 * Partly implemented INFO command on client and server side.
7225 Fixed CLEAR command. Changes to SERVER command; show current
7226 server(s) when giving command without arguments. Added
7227 VERSION command to client.
7229 * Added check to server that unregistered connections cannot
7230 execute commands (unless it is specificly allowed).
7232 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7234 * Fixed screen refresh.
7236 * Fixed channel joining bug from client. On some circumstances
7237 client tried to join to a channel it had already joined.
7239 * Added public key verification process into client's protocol.c.
7240 The client now verifies the public key from user and saves
7241 it into ~./silc/serverkeys/ directory.
7243 Added into: clientutil.[ch]: silc_client_verify_server_key.
7245 * Changed SKE protocol's silc_ske_initiator_finish function
7246 to accept callback function that verifies the received public
7247 key. Removed old silc_ske_verify_public_key function.
7249 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7252 silc_pkcs_private_key[_data]_set.
7254 * Made the password and public authentication more cleaner in
7255 server's protocol.c.
7257 * Removed historic and obsolete protocol `channel_auth' from
7258 both client and server.
7260 * Removed wrong way of sending command status messages from
7261 server to client in server's command.c. The old way violated
7262 protocol specification.
7264 Changes to silccore/silccommand.[ch]: removed
7265 silc_command_encode_status_payload -> not needed anymore,
7266 changed silc_command_encode_payload_va to accept extra
7267 argument on variable argument list. The argument type must
7268 now be provided to the function. Also, added new function:
7269 silc_command_encode_reply_payload_va which is same as
7270 normal command_encode_payload_va except command status type
7271 is provided as extra argument.
7273 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7275 * Added ~./silc directory handling. The directory includes the
7276 public and private keys for the client.
7278 Added silc_client_check_silc_dir, silc_client_create_identifier
7279 and silc_client_load_keys.
7281 * Implemented SILC protocol compliant public key. Added public
7282 and private key saving to and loading from files.
7284 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7285 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7286 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7287 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7288 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7290 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7291 silc_pkcs_load_[public/private]_key.
7293 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Added silc_server_get_route (route.[ch]) to get connection
7296 data for the fastest route for given ID.
7298 * Implemented INVITE command on client and server. The command
7299 were re-defined in the SILC Protocol Specification and the
7300 implementation now complies with the specification.
7302 * Implemented PING command on client and server.
7304 * Implemented NAMES command on client and server. The server side
7305 supports currently only normal server not router server yet.
7306 Some changes to NAMES definition in SILC protocol specification.
7308 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Implemented LEAVE command on client and server.
7312 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7313 again. This change was made to the protocol as well. Server
7314 should not violate the protocol specification anymore.
7316 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7318 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7319 was tested. SOCKS4 was not but should work anyway.
