166 the SKE interface a bit.
168 * Fixed padding problem in PKCS#1. The padding was not actually
169 random since the random number generator was used incorrectly.
170 This security bug affects only when encrypting with PKCS#1, and
171 it is not currently used at all in SILC. SILC only use signing
172 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

253 algorithm parts and created new file silcalgs.conf, that
254 is now included from the example_silcd.conf.in.
256 * Optimized the silc_server_connect_to_router_second to take
257 the connection configuration object from the SilcServerConnection
258 object instead of finding it during the connecting phase.
259 Added the configuration object to SilcServerConnection struct.
260 Affected files silcd/server_internal.h, server.c.

288 public key is set. If not set, public key is preferred.
289 This has effect only when being initiator (responder will try
292 Added support for authentication with passphrase and public key
293 at the same time. The passphrase is tried first always since
294 it is faster to check.
296 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
298 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

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

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

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

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

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

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

562 change founder's mode than the founder itself, there was a
563 little bug. Affected file silcd/command.c.
565 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
567 * Removed the SilcClientCommandDestructor from the client
568 libary, it is not needed anymore. Affected files are
569 lib/silcclient/silcapi.h, command[_reply].[ch],
570 client_notify, idlist.c.
572 * Fixed GETKEY command to first resolve client, and then
573 resolve the server only if the client was not found, instead
574 of resolving both at the same time. Affected file is
575 lib/silcclient/command.c.
577 * Added silc_client_start_key_exchange_cb and lookup the
578 remote hostname and IP address before starting the key
579 exchange with server. The affected file is
580 lib/silcclient/client.c.
582 * The server's public key is now saved using the IP address
583 of the server and not the servername for the filename.
584 The hostname public key filename is checked as an fall back
585 method if the IP address based filename is not found.
587 Fixed the GETKEY command to save the fetched server key
590 Print the remote server's hostname now when new key is
591 received during connection process. Affected file is
592 irssi/src/silc/core/client_ops.c.
594 * Return always our own public key to the client if it asks
595 for it with GETKEY command. Affected file silcd/command.c.
597 * Removed the use_auto_addr variable from default config
598 file since it was in wrong section. Affected file is
601 * Fixed TOPIC_CHANGE notification to not route it when it
602 was sent using silc_server_send_notify_to_channel function.
603 Affected file silcd/command.c.
605 * Fixed silc_server_send_notify_kicked to send the kicker's
606 Client ID also, it was missing. Affected files are
607 silcd/command.c, silcd/packet_send.[ch].
609 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
611 * Do not save client history information in SERVER_SIGNOFF.
612 Fixes the bug in normal server that it does not detect
613 the client becoming valid after the server becomes back
614 online. Affected file silcd/server_util.c.
616 * Added `sock_error' field into the SilcSocketConnection
617 context. When error occurs during socket operation (read
618 or write) the error is saved. Added also new function
619 silc_socket_get_error to return human readable socket error
620 message. Affected files are lib/silcutil/silcsockconn.[ch],
621 lib/silcutil/unix/silcunixsockconn.c, and
622 lib/silcutil/win32/silcwin32sockconn.c.
624 * The server now prints the socket error message in the
625 signoff for client. Affected file silcd/server.c.
627 * Fixed the `created' channel information sending from router
628 to server in JOIN command. Checks now whether the channel
629 really was created or not and set it according that.
631 Fixed the JOIN command to use the client entry's current
632 ID during the joining procedure instead of the one it sent
633 in the command (it is checked though), since it can change
634 between the packet processing and command processing, and
635 would just case unnecessary pain in the client end. Affected
636 file silcd/command.c.
638 * Fixed a channel key payload sending to use correct channel
639 ID when the server was forced to change the channel's ID by
640 router. Router sent the key payload with the old Channel ID.
641 Affected file silcd/packet_receive.c.
643 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Call silc_server_save_channel_key only if the key payload
646 was provided in the JOIN command's command reply. Affected
647 file silcd/command_reply.c.
649 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
651 * Fixed silc_mp_sizeinbase to return the value correctly with
652 MPI. Affected file lib/silcmath/mp_mpi.c.
654 * Fixed the stop_server signal to correctly stop the scheduler
655 and gracefully stop the server when SIGTERM or SIGINT signals
656 are received. Affected file silcd/silcd.c.
658 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
660 * Simple handling of TERM and HUP signals. Also added some log
661 flushing call around. Affected file is
664 * Fixed small bugs in silclog.c. Now buffering output will take
665 effect after 10 seconds since startup: This will ensure that
666 no important startup messages are lost. Also output redirection
667 will preserve original format ([Date] [Type] message).
668 Affected file is lib/silcutil/silclog.c.
670 * Added two options to the config file, in the logging section:
671 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
672 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
674 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
676 * Do not print the warning about log files not being initialized
677 more than once to avoid excess logging. Affected file is
678 lib/silcutil/silclog.c.
680 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
681 the SIM copying in make install in Makefile.am.pre.
683 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
685 * Rewritten silclog APIs. Globally interesting changes follows:
686 silc_log_set_files() changed to silc_log_set_file().
687 silc_log_set_callbacks() changed to silc_log_set_callback().
688 ROBOdoc documented silclog header file.
689 SilcLogCb now returns bool to wether inihibit the default
690 handler or not (to keep the old behaviour return always TRUE).
691 The new APIs should also fix the problem of the
692 silcd_error.log file that was written in the current directory.
695 Log files streams will remain opened after silc_log_set_file()
696 call, means less CPU usage notably on high traffic servers.
697 File streams are now full buffered, and flushed to the disk
698 every 5 minutes, lesses HD activity and CPU usage.
699 Messages can be redirected, allowing admins to configure
700 one single logfile for all server messages.
701 the silc_log_quick global variable to activate fast-logging.
702 Affected files lib/silcutil/silclog.[ch]
704 * Changed some code to conform new silclog APIs. Affected
705 files are doc/example_silcd.conf.in, silcd/server.c
706 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
709 * Fixed a memory leak that could occur in some situations.
710 Affected file silcd/serverconfig.c.
712 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
714 * Added the silc_client_del_client to remove the client from
715 all channels as well. Affected file lib/silcclient/idlist.c.
717 * Fixed the client library to correctly remove the client
718 from all channels when the client entry is being destroyed.
719 Affected file lib/silcclient/client_notify.c, command.c.
721 * Added auto-nicking support to the client library. If the
722 applicatio now sets client->nickname it will be sent to the
723 server after connecting by the library. This way for example
724 SILCNICK (or IRCNICK) environment variables will have effect
725 and always change the nickname automatically to whatever
726 it is wanted. Affected file lib/silcclient/client.[ch].
728 * Renamed silc_server_command_bad_chars to the
729 silc_server_name_bad_chars and moved it to the
730 silcd/server_util.[ch]. Added also new function
731 silc_server_name_modify_bad to return nickname that
732 includes bad characters as new nickname without those
733 bad characters. This check and modify is now used in
734 silc_server_new_client when the username is initially set
735 as nickname, so it must be checked to be valid nickname.
736 Affected file silcd/packet_receive.c.
738 * The nickname length is now taken from the packet for real
739 and not trusted to strlen() since it clearly can return
740 wrong length for nickname including bad characters. This
741 also applies to channel names. Affected file silcd/command.c.
743 * Removed the lib/silcsilm/modules directory. Modules are now
744 compiled into the lib/silcsim. Fixed the copying of the
745 modules to follow symbolic links in Makefile.am.pre.
747 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
749 * Fixed silc_string_regexify list creation. Fixes bugs with
750 BAN and INVITE commands in server. The affected file is
751 lib/silcutil/unix/silcunixutil.c.
753 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Removed the command destructor entirely from the server's
756 command and command reply routines. It is not needed, and
757 its usage was buggy and caused crashes. Affected files are
758 silcd/command[_reply].[ch].
760 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
762 * Cancel protocol and NULL sock->protocol if timeout
763 occurred during protocol. Affected file silcd/server.c.
765 * Cancel protocol timeouts always before calling the final
766 callback, to assure that after final callback is called
767 no other state will be called for the protocol anymore.
768 Affected file silcd/protocol.c.
770 * Print error log if incoming connection configuration could
771 not be found. Affected file silcd/server.c.
773 * Fixed JOIN command to correctly save the founder mode
774 to the client on normal SILC server, when the channel
775 was created by the router. Affected file silcd/command.c.
777 * Fixed LIST command (hopefully) to send correct reply
778 packets. Affected file silcd/command.c.
780 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
782 * The silc_packet_receive_process now returns FALSE if the
783 read data was invalid packet, and TRUE if it was ok.
785 The server now checks that if unauthenticated connection
786 sends data and its processing fails the server will close
787 the connection since it could be a malicious flooder.
789 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
791 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
793 * Make sure the warning about error opening a log file is
794 printed only once and not everytime it fails (produces
795 too much useless log). Affected file lib/silcutil/silclog.c.
797 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
799 * Made the silc_server_daemonise() function more readable.
800 Affected file silcd/server.c.
802 * Pid file is now optional, the user may comment it out from
803 the config file. Removed define SILC_SERVER_PID_FILE, we
804 don't need a default any longer. Affected file
805 configure.in.pre, lib/Makefile.am.pre.
807 * Make some use of the pid file. The server now dies at startup
808 if it detects a valid pid file on his path. The server would
809 die anyway in this circumstance, because of the bind() failure.
810 Affected file silcd/silcd.c.
812 * No longer compiling lib/dotconf.
814 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
816 * Fixed JOIN command parsing not to crash. Affected file
817 lib/silcclient/command.c.
819 * Fied the NICK_CHANGE notify to add the new client entry
820 even it is resolved. This removes an <[unknown]> nick
821 thingy bug in the client. Affected file is
822 lib/silcclient/client_notify.c.
824 * Do not try to allocate 0 bytes (efence does not like it)
825 in lib/silccore/silccomand.c when encoding payload.
827 * Do not take IRCNICK as nickname in Irssi SILC client since
828 it is not possible to set nickname before hand connecting
829 the server (TODO has an entry about adding auto-nicking
832 * Changed the silc_server_command_pending to check whether
833 there already exists an pending entry with the specified
834 command, command identifier and pending callback. This is
835 to fix IDENTIFY and WHOIS related crashes that may register
836 multiple pending commands with same identifier. Affected
837 file silcd/command.c.
839 * Fixed the server to reconnect to the router even if it
840 was already reconnecting and EOF was received. This to
841 fix a possibility that the server wouldn't ever try to
842 auto-reconnect to the router. Affected file silcd/server.c.
844 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Fixed the server's password authentication to use the
847 length of the locally saved password, and not the one
848 sent in the packet. Affected file silcd/protocol.c.
850 * Fixed same password authentication problem in the
851 Authentication Payload handling routines in
852 lib/silccore/silcauth.c.
854 * Yet another password authentication problem fixed with
855 channel password handling in silcd/command.c.
857 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
859 * If first character of string in silc_parse_userfqdn is '@'
860 then do not parse it. Affected file is
861 lib/silcutil/silcutil.c.
863 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Fixed minor bug in IDENTIFY command reply sending, which
866 caused various weird problems during JOIN when it was
867 resolving names for users. Affected file silcd/command.c.
869 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Fixed the IDENTIFY command reply sending to chech better valid
872 clients. It was possible to send incomplete list of replies.
873 Affected file silcd/command.c.
875 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
877 * Added silc_client_command[s]_[un]register functions now to
878 dynamically register the commands in client library. Removed
879 the static table of commands. This allows the client library
880 to call commands without causing the application to know about
881 what commands library has called.
883 Removed the INFO command reply kludge to detect when the command
884 was called by library. Now library use its own command reply
885 function for INFO command.
887 Added function silc_client_command_call to call a command.
888 Application can use it to call command, not access the structure
891 Now all commands that are sent by the client library (not
892 explicitly sent by application) use own command reply functions.
894 Affected files around lib/silcclient/ and in
895 irssi/src/silc/core/.
897 * Fixed the WHOIS command reply sending to chech better valid
898 clients. It was possible to send incomplete list of replies.
900 Fixed the WHOIS and IDENTIFY to send the request to router
901 if normal server did not do it and did not find any results.
903 Affected file silcd/command.c.
905 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Moved the internal data from SilcClient context into its
908 own file, not accesible to application. Affected files
909 lib/silcclient/client.h and lib/silcclient/client_internal.h,
910 and other files in client library.
912 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Added doc/examples installation target in Makefile.am.pre.
917 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
919 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
920 commands the found client entry will be removed from the
921 cache, after notifying application about the error. Affected
922 file lib/silcclient/command_reply.c.
924 * Changed the /MSG to check for exact nickname user gave, and
925 not let `nick' match `nick@host' if it is only one found. Now,
926 user must type the exact nickname (like nick@host2) even if
927 there are no more than one same nicks found. This is to avoid
928 a possibility of sending nickname to wrong nickname since
929 `nick' could match `nick@host'. Affected file is
930 irssi/src/core/silc-servers.c.
932 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
934 * Do not print "you are now server operator" or similar when
935 giving /away command. Affected files are
936 irssi/src/silc/core/client_ops.c, silc-servers.h.
938 * Made the silc_server_command_pending_error_check to send
939 the same command reply payload it received back to the
940 original sender of the command. This way all arguments
941 that was received by the server will be received by the
942 client too. Affected file silcd/command.c.
944 * Added the silc_idcache_add to return the created cache entry
945 to a pointer. Affected file lib/silccore/silcidcache.[ch].
947 * Add global clients to expire if they are not on any channel.
948 This is because normal server will never know if they signoff
949 if they are not on any channel. The cache expiry will take
950 case of these entries. This is done by normal servers only.
951 The affected files are silcd/command_reply.c,
952 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
954 * If server receives invalid ID notification for WHOIS or
955 IDENTIFY and the ID exists in the lists, it is removed.
956 Affected file silcd/command_reply.c.
958 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
959 in client then client entry that it matches is searched and
960 the nickname is printed on the screen for user. Affected
961 file irssi/src/silc/core/client_ops.c.
963 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
965 * Use cache entry expire time in the LIST command reply to
966 purge old entries from the cache after the LIST command
967 reply has been received. This way we don't have non-existent
968 entries in the cache for too long. Affected file is
969 silcd/command_reply.c.
971 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
973 * If we are normal server, and we've not resolved client info
974 in WHOIS or IDENTIFY from router, and it is global client,
975 we'll check whether it is on some channel. If it is not
976 then we cannot be sure about its validity and will resolve it
977 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
978 file silcd/command.c.
980 * Search channel by name (if possible) rather than by ID
981 in IDENTIFY command's command reply. Affected file is
982 silcd/command_reply.c.
984 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
986 * Distribute to the channel passphrase in CMODE_CHANGE notify.
987 Updated specs and implemented it. Affected file silcd/command.c,
988 silcd/packet_send.c and silcd/packet_receive.c.
990 * Implemented the <founder auth> payload handling in the JOIN
991 command. If provided all conditions for channel joining
992 except requirement to provide correct passphrase can be
993 overrided by the channel founder. Updated the protocol specs.
994 Affected file silcd/command.c.
996 Added support for founder auth in JOIN command in client
997 library. Fixed the parsing of the JOIN command now to support
998 all options as they should be. The affected file is
999 lib/silcclient/command.c.
1001 * Optimized the WHOIS and IDENTIFY commands to send the request
1002 to router only if it includes nicknames or other names. If
1003 they include only IDs then check the local cache first before
1004 routing. Affected file is silcd/command.c.
1006 * Added channels topic announcements. Affected file is
1007 silcd/packet_receive.c and silcd/server.c.
1009 * Fixed the silc_server_send_notify_topic_set to really destine
1010 the packet to channel. Affected file silcd/packet_send.c.
1012 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1013 library. Affected file lib/silcclient/client_notify.c.
1015 * Added UMODE announcements. Affected file silcd/server.c.
1017 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1019 * Memory leak fixes in:
1021 lib/silcutil/silcsockconn.c
1022 lib/silcske/silcske.c
1023 lib/silcske/groups.c
1025 lib/silccrypt/silcpkcs.c
1026 lib/silccore/silccommand.c
1027 lib/silccore/silcidcache.c
1032 * ROBOdoc documented the lib/silcske/groups.h file and a
1033 bit changed the interface for better.
1035 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1037 * Update the client entry context in the ID cache after
1038 nick change. Affected file lib/silcclient/command.c.
1039 Fixes the CUMODE command when regaining founder privileges,
1040 and a little WHOIS problem.
1042 * Fixed silc_net_gethostbyname to correctly call the
1043 inet_ntop. Affected file lib/silcutil/silcnet.c.
1045 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1047 * Added IPv6 support checking to the configure.in.pre, added
1048 also --enable-ipv6 option to override the check. Affected
1049 file configure.in.pre.
1051 * The silc_thread_create now calls the start function
1052 directly if threads support is not compiled in. Removes
1053 ugly #ifdef's from generic code. Affected files are
1054 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1056 * Added silc_net_gethostby[name/addr]_async to asynchronously
1057 resolve. Affected files are lib/silcutil/silcnet.[ch].
1059 * Added support for rendering IPv6 based server, client and
1060 channel IDs. Affected file lib/silcutil/silcutil.c.
1062 * Added support for creating IPv6 based server IDs. Affected
1063 file is silcd/serverid.c.
1065 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1067 * Added silc_net_gethostby[addr/name] into the
1068 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1069 routines. Added silc_net_is_ip[4/6]. Affected file is
1070 lib/silcutil/unix/silcunixnet.c. All routines that take
1071 address as argument now supports both IPv4 and IPv6 addresses.
1073 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1075 * Fixed LIST command reply sending in server. Affected file
1078 * Server now sends the kicker's client ID in the KICK notify
1079 to the kicked client. Affected file silcd/command.c.
1081 * The client library now parses the kickers client ID and
1082 UI displays it. Affected files lib/silcclient/client_notify.c
1083 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1085 * Made all payload parsing function prototypes consistent.
1086 They all take now const unsigned char * and uint32 pair as
1087 the payload data instead of SilcBuffer. Changes all around
1088 the source tree. Other unsigned char* -> const unsigned char*
1089 changes around the tree as well.
1091 * Optimized SFTP client and server packet sending not to
1092 allocate new buffer for each packet but to recycle the
1093 first allocated buffer. Affected files are
1094 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1096 * Optimized the SFTP client to use SilcList instead of
1097 SilcDList for requests, because it is faster. Affected file
1098 is lib/silcsftp/sftp_client.c.
1100 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1101 into lib/silccore/silcid.[ch].
1103 Renamed silcpayload.[ch] into silcargument.[ch].
1105 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * If client entry is deleted with active key agreement
1108 session, abort the session.
1110 The silc_client_abort_key_agreement now calls the completion
1111 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1113 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1116 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Don't use __restrict in older GCC's. Affected file is
1119 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1121 * silc_net_localhost now attempts to reverse lookup the
1122 IP/hostname. Affected file lib/silcutil/silcnet.c.
1124 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1125 command. It can be used to gain founder privileges at
1126 the same time when joining the channel.
1128 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1129 kicker's client ID as well. Updated protocol specs.
1131 Defined that the server must send SILC_COMMAND_IDENTIFY
1132 command reply with error status to client who sent
1133 private message with invalid client ID.
1135 Updated the protocol specification.
1137 * Added silc_server_send_command_reply to send any
1138 command reply. Affected file silcd/packet_send.[ch].
1140 * Added silc_id_payload_encode_data to encode ID payload
1141 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1143 * The server now send IDENTIFY command reply with error
1144 status if client ID in private message is invalid. Affected
1145 file silcd/packet_receive.c.
1147 * Save the server key file with server's IP address in
1148 the filename instead of hostname. The affected file is
1149 irssi/src/silc/core/client_ops.c.
1151 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1153 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1156 * Added libtool support for compiling shared objects in
1157 lib/silcsim. Affected file configure.in.pre and
1158 lib/silcsim/Makefile.am. Original patch by cras.
1160 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Pid file configuration, and server's config file fixes
1163 patch by toma. Updated CREDITS file.
1165 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Fixed silc_client_channel_message to not try to decrypt
1168 the message twice if it resolved the destination client
1169 information. This could cause of dropping one channel
1170 message. Affected file lib/silcclient/client_channel.c.
1172 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1175 lib/silcclient/client.c. This function is used when the SILC
1176 Client is run under some other scheduler, or event loop or
1177 main loop. On GUI applications, for example this may be
1178 desired to used to run the client under the GUI application's
1179 main loop. Typically the GUI application would register an
1180 idle task that calls this function multiple times in a second
1181 to quickly process the SILC specific data.
1183 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1185 * Fixed silc_server_drop() for dropping the supplementary
1186 groups as well, this could cause a security hole on some
1189 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1194 * Write PID file after dropping privileges. Added -F option
1195 to run server on foreground. A patch by debolaz.
1196 Affected files silcd/server.c, silcd/silcd.c.
1198 * Fixed MOTD to return the MOTD file server name. Affected
1199 file silcd/command.c.
1201 * Added INFO command reply handling to the Irssi SILC Client.
1202 Affected file irssi/src/silc/core/client_ops.c.
1204 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Fixed the silc_idcache_list_* routines to really support
1207 the dynamic list. Fixes a crash. Affected file is
1208 lib/silccore/silcidcache.c.
1210 * Fixed the LIST command reply to really call LIST command's
1211 pending callbacks. Affected file silcd/command_reply.c.
1213 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Update conn->local_entry->nickname after giving NICK
1216 command. Affected file lib/silcclient/command.c.
1218 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1220 * Added the [pid] option to the silcd configuration file
1222 Affected files: serverconfig.[ch] and silcd.c
1224 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Save fingerprint in WHOIS command reply in server.
1227 Affected file silcd/command_reply.c.
1229 * Fixed NICK commands pending callback registration.
1230 Affected file lib/silcclient/command.c.
1232 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1234 * Use ++server->cmd_ident when sending commands in server,
1235 instead of random number. Affected file silcd/command.c.
1237 * Fixed GETKEY command reply to call actually GETKEY pending
1238 command callbacks. Affected file silcd/command_reply.c.
1240 * A bit stricter check for nicknames. Check for same nickname
1241 in NICK command also. Affected file silcd/command.c.
1243 * Do not call INFO command everytime client ID changes, only
1244 during first connecting. Affected file lib/silcclient/client.c.
1246 * Set the new nickname only after successful command reply for
1247 NICK command is returned by server. Affected file
1248 lib/silcclient/command.c.
1250 * Remove nicknames from nicklist during server_signoff notify.
1251 Should fix /NAMES bit more. The affected file is
1252 irssi/src/silc/core/silc-channels.c.
1254 * Added `fingerprint' field to the SilcIDListData in the
1255 silcd/idlist.h to hold the fingerprint of the client's
1258 Send the fingerprint of the client's public key in WHOIS
1261 Affected files silcd/command.c, and silcd/idlist.[ch].
1263 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1264 create fingerprint from given data.
1266 * Show the fingerprint of the client's public key in WHOIS.
1267 Affected files irssi/src/module-formats.[ch] and
1268 irssi/src/silc/core/client_ops.c.
1270 * Format the multiple same nicknames also during JOIN and
1271 NICK_CHANGE notifys. Affected file is
1272 lib/silcclient/client_notify.c.
1274 * Do not print error on screen for invalid private message
1275 payload since it can come if someone is sending private
1276 messages with wrong key. Affected file
1277 lib/silccore/silcprivate.c.
1279 * Fixed multiple concurrent /PING crash. Affected file
1280 lib/silcclient/command.c.
1282 * Changed the wrong ID encoding. All IP addresses must be
1283 in MSB first order in encoded format. They were encoded
1284 wrong and was in LSB format. Affected files are
1285 silcd/serverid.c, lib/silcutil/silcutil.c.
1287 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1289 * Call the `connect' client operation through the scheduler
1290 in case of error. Affected file lib/silcclient/client.c.
1292 * Call the `failure' client operation even if the error
1293 occurred locally during a protocol. Affected file is
1294 lib/silcclient/protocol.c.
1296 * Added support of sending LIST command to router from normal
1297 server. This way normal server can get list of all channels
1298 in the network too. Fixed the channel list sending in the
1299 server too. Affected files are silcd/command.c, and
1300 silcd/command_reply.[ch].
1302 * Added silc_server_update_channels_by_server and
1303 silc_server_remove_channels_by_server. They are used during
1304 disconnection of primary router and in backup router protocol.
1305 Affected file silcd/server_util.[ch], silcd/server.c and
1306 silcd/server_backup.c.
1308 * Fixed channel adding to global list in IDENTIFY command
1309 reply in server. Affected file silcd/command_reply.c.
1311 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * If the incoming packet type is REKEY or REKEY_DONE process
1314 that packet always synchronously. Fixes yet another MAC
1315 failed error on slow (dialup) connections. Affected file
1316 lib/silcclient/client.c and silcd/server.c.
1318 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1320 * Call check_version SKE callback for initiator too. Affected
1321 file lib/silcske/silcske.c.
1323 * Implemented fix for security hole found in the SKE that was
1324 fixed in the specification few days back; the initiator's
1325 public key is now added to the HASH value computation.
1326 Added backwards support for the old way of doing it too, for
1327 old clients and old servers. Affected file is
1328 lib/silcske/silcske.c.
1330 * Enabled mutual authentication by default in SKE. If initiator
1331 is not providing mutual authentication the responder will
1332 force it. This will provide the proof of posession of the
1333 private key for responder. The affected files are
1334 lib/silcclient/protocol.c and silcd/protocol.c.
1336 * Do not cache anymore the server's public key during SKE.
1337 We do mutual authentication so the proof of posession of
1338 private key is done, and if the server is authenticated in
1339 conn auth protocol with public key we must have the public
1340 key already. Affected file silcd/protocol.c.
1342 * Added new global debug variable: silc_debug_hexdump. If
1343 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1344 file lib/silcutil/silclog.[ch].
1346 * Fixed compilation warning due to char * -> const char *.
1347 Affected files lib/silcutil/silcnet.h, and
1348 lib/silccore/silcauth.[ch].
1350 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Fixed CMODE command when new channel key was created. If
1353 the creation failed the old key was removed. Next time giving
1354 same command would crash the server since the old key was
1355 freed already. Affected file silcd/command.c.
1357 * Fixed the silc_server_announce_get_channels to not crash
1358 on reconnect. Affected file silcd/server.c.
1360 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Added silc_log_set_debug_string function to set a regex
1363 string to match for debug output. Only the function names,
1364 or filenames matching the given debug string is actually
1365 printed. This way it is possible to filter out those debug
1366 strings that user is not interested in.
1368 Fixed a bug in silc_string_regexify.
1370 Affected files lib/silcutil/silclog.[ch], and
1371 lib/silcutil/unix/silcunixutil.c.
1373 * Changed the -d options in both server and Irssi SILC client
1374 to take the debug string as argument. Affected files
1375 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1377 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Added silc_hash_babbleprint to create a Bubble Babble
1380 Encoded fingerprint. The encoding is developed by Antti
1381 Huima (draft-huima-babble-01.txt), and it creates human
1382 readable strings out of binary data. Affected file
1383 lib/silccrypt/silchash.[ch].
1385 * Print the babble print now in addition of fingerprint as well
1386 in Irssi SILC client. Affected files are
1387 irssi/src/fe-common/silc/module-formats.[ch],
1388 irssi/src/fe-common/silc/core/client_ops.c.
1390 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Fixed a security problem found in SKE. The initiator's
1393 public key too is now added to the HASH hash value creation
1394 which is signed by the responder to create the SIGN value.
1395 This will prevent anyone in the middle to lie to the responder
1396 about the initiator's public key. If this is done now, the
1397 man in the middle will get caught. Updated the protocol
1400 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Better installation directory handling. Configure module
1403 paths and other paths automatically to example_silc* files
1404 in doc/. A patch by toma.
1406 * Fixed compiler warning from MPI library, and from SILC RNG.
1409 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1410 It can be configured with ./configure. A patch by toma.
1412 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * Find correct make to use in prepare-clean. A patch by
1415 toma. Affected file prepare-clean.
1417 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1419 * Added irssi variables use_auto_addr, auto_bind_ip,
1420 auto_bind_port and auto_public_ip.
1422 * Changed the interface for silc_client_send_key_agreement
1423 in lib/silcclient/silcapi.h
1427 irssi/src/silc/core/silc-core.c
1429 lib/silcclient/silcapi.h
1430 irssi/src/silc/core/silc-channels.c
1431 lib/silcclient/client_keyagr.c
1434 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Added silc_pkcs_public_key_compare to compare two
1437 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1439 * Check that the client who set the founder mode on the
1440 channel is the same client that is giving the founder
1441 mode to itself. It is done by comparing the saved public
1442 key (it is saved even in the authentication is passphrase).
1443 Affected file silcd/command.c.
1445 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Do not process packet for disconnected socket connection.
1448 Affected file lib/silccore/silcpacket.c.
1450 * Process the DISCONNECT packet through scheduler in the
1451 client library. Affected file lib/silcclient/client.c.
1453 * Fixed the silc_client_packet_parse to not to increase
1454 the packet sequence number if the conn->sock and the
1455 current socket connection is not same. This can happen
1456 for example during key agreement when the conn includes
1457 multiple socket connections (listeners). Affected file
1458 lib/silcclient/client.c.
1460 * The sender of the file transfer request now provides also
1461 the pointer (listener) for the key exchange protocol. If
1462 the listener cannot be created then it sends empty key
1463 agreement and lets the receiver provide the listener.
1465 Added `local_ip' and `local_port' arguments to the
1466 silc_client_file_send. If they are provided they are used,
1467 if not then it will attempt to find local IP address, if
1468 not found or bind fails then the remote client will provide
1471 Affected files are lib/silcclient/client_ftp.c and
1472 lib/silcclient/silcapi.h.
1474 * Extended the FILE SEND command to support defining the
1475 local IP and port for key exchange listener. They are
1476 optional. Affected file irssi/src/silc/core/silc-servers.c.
1478 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1480 * Defined to WHOIS command reply the sending of fingerprint
1481 of the client's public key (if the proof of posession of the
1482 corresponding private key is verified by the server).
1483 Updated to the protocol specification.
1485 * Added support of receiving the client's public key's
1486 fingerprint in command reply in client library. Affected
1487 file is lib/silcclient/command_reply.c, and
1488 lib/silcclient/idlist.[ch].
1490 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Do not send over 128 chars long nickname to the server
1493 in NICK command. Affected file lib/silcclient/command.c.
1495 * Do not send over 256 chars long channel names to the server
1496 in JOIN command. Affected file lib/silcclient/command.c.
1498 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Assure that silc_server_close_connection cannot be called
1501 twice for same socket context. Affected file is
1504 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Send error message to application if opening file for
1507 writing during file transfer fails. Affected file is
1508 lib/silcclient/client_ftp.c.
1510 Remove all file transfer sessions for a client that we're
1511 removing from ID cache.
1513 Affected file is lib/silcclient/client_ftp.c.
1515 * Fixed silc_net_addr2bin to return correct address. Affected
1516 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1518 * Fixed file transfer session removing on signoff notify.
1519 Affected file irssi/src/silc/core/silc-servers.c.
1521 * Added the SilcClientFileError to be returned in the monitor
1522 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1523 Affected file lib/silcclient/silcapi.h.
1525 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1527 * Fixed a crash in silc_client_ftp_free_sessions and
1528 silc_client_ftp_session_free_client. Affected file
1529 lib/silcclient/client_ftp.c.
1531 * Added `disabled' field in the SilcChannelEntry in the server
1532 to indicate if the server entry is disabled. Affected file
1533 silcd/idlist.h, silcd/command[_reply].c.
1535 * SILC server adds now /var/run/silcd.pid everytime it is
1536 started. Affected file silcd/silcd.c.
1538 * Added silc_server_packet_send_clients to send a packet to
1539 the provided table of client entries. Affected file
1540 silcd/packet_send.[ch].
1542 * Fixed a crash in client resolving in client_prvmsg.c in
1543 client library. Affected file lib/silcclient/client_prvmsg.c.
1545 * Do not actually remove the client directly from ID cache
1546 during SERVER_SIGNOFF, but invalidate it. This way we
1547 preserve the WHOWAS info for the client. Affected file
1548 silcd/server_util.c.
1550 * Fixed SERVER_SIGNOFF notify handling in the server. The
1551 server is now able to process incoming SERVER_SIGNOFF notify
1552 for a server that it doesn't even know about. It will remove
1553 the clients provided in the notify. Affected file
1554 silcd/packet_receive.c.
1556 * Check for partial packet in data queue after every packet that
1557 was found from the queue. Return and wait for more data if
1558 there is partial data in queue. Affected file is
1559 lib/silccore/silcpacket.c.
1561 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Added SilcClietFileError enum to indicate error in
1564 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1565 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1566 Affected files lib/silcclient/silcapi.h and
1567 lib/silcclient/client_ftp.c.
1569 * Check that newsize in silc_buffer_realloc is larger than
1570 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1572 * Added better monitor of file transfers. It now monitors
1573 key agreement protocol during the file transfer too. Added
1574 error reporting too. Affected files
1575 irssi/src/silc/core/silc-servers.c,
1576 irssi/src/fe-common/silc/module-formats.[ch].
1578 * Wrote a help file for FILE command.
1580 * Added silc_rng_global_get_byte_fast to get not-so-secure
1581 random data as fast as possible. Random data is read from
1582 /dev/urandom if available and from the SILC RNG if not
1583 available. It is used in padding generation. Affected file
1584 lib/silccrypt/silcrng.[ch].
1586 * All packets in client library are now processed synchronously.
1587 Optimized packet processing a lot. Affected file
1588 lib/silcclient/client.c.
1590 * All server connection packets are processing synchronously
1591 now in server, to optimize packet processing. Affected file
1594 * Include files are installed now only in Toolkit distribution
1595 if make install is given. Affected files: all Makefile.am's.
1597 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * Assure that silc_client_notify_by_server_resolve does not
1600 resolve the client information multiple times. If it cannot
1601 be found by the first it cannot be found at all. Affected
1602 file lib/silcclient/client_notify.c.
1604 * Fixed WHOWAS command reply calling. Affected file
1605 lib/silcclient/command_reply.c.
1607 * Removed all references to silc_idlist_get_client from the
1608 Irssi SILC client since that call is internal call used by
1609 the library. The Irssi SILC client will use now client
1610 retrieval functions found in silcapi.h.
1612 * Fixed a bug in resolving nickname info before sending
1613 private message. It used freed memory. Affected file
1614 irssi/src/silc/core/silc-servers.c.
1616 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Assure my_channels statistics cannot go negative in server.
1619 Affected files silcd/server.c, silcd/server_util.c.
1621 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1625 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1627 * Win32 Toolkit changes. Affected files
1628 win32/silc.dsw, win32/libsilc/libsilc.def,
1629 win32/libsilcclient/libsilc.def,
1630 lib/silcutil/silcutil.c, and
1631 lib/sftp/sftp_fs_memory.c.
1633 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * Added silc_net_localip to return local host's IP address.
1636 Affected file lib/silcutil/silcnet.[ch].
1638 * If key exchange or rekey protocol is active for a connection
1639 parse all packets syncronously since there might be packets
1640 in packet queue that we are not able to process without first
1641 processing packets before them. Affected file silcd/server,
1642 lib/silcclient/client.c.
1644 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1645 whether library should continue processing the packet.
1646 Affected file lib/silccore/silcpacket.h.
1648 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1649 SilcSFTPMonitorData to SFTP server to monitor various
1650 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

1677 lib/silcutil/silcutil.[ch].
1679 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Resolve the client info when received private message or
1682 channel message for a client which nickname we don't know.
1683 Affected files lib/silcclient/client_prvmsg.c and
1684 lib/silcclient/client_channel.c.
1686 * Do not crash in /KEY if client is not connected. Affected
1687 file irssi/src/silc/core/silc-channels.c.
1689 * Added SilcClientStatus field to the SilcClientEntry in the
1690 lib/silcclient/idlist.h.
1692 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1693 is incomplete and is being resolved, it won't be resolved
1696 Make sure also that USERS command reply does not resolve
1697 twice information. Affected file is
1698 lib/silcclient/command_reply.c.
1700 Make sure that silc_client_get_clients_by_list does not
1701 resolve twice same information.
1703 * Check for valid client->id in the silc_server_free_client_data.
1704 Affected file silcd/server.c.
1706 * Fixed /GETKEY nick@server not to crash if the server entry
1707 is not found. Affected file lib/silcclient/command.c.
1709 * Fixed the silc_server_check_cmode_rights to check the
1710 requested modes correctly. Affected file silcd/command.c.
1712 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Better checks for non-printable chars in nick added.
1715 Affected file silcd/command.c.
1717 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Call the silc_server_udpate_servers_by_server in the
1720 primary router that comes back online in the backup resuming
1721 protocol. Otherwise it routes packets wrong. Affected file
1722 silcd/server_util.[ch], silcd/server_backup.c.
1724 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1727 lib/silcutil/silcbuffmt.[ch].
1729 * Redefined the SILC packet header to include the padding
1730 length. Affected file lib/silccore/silcpacket.[ch].
1732 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1733 length for maximum padding up to 128 bytes). Affected
1734 file lib/silccore/silcpacket.h.
1736 * Removed all backwards support for old 0.5.x MAC thingies.
1737 The SILC packet header change makes it impossible to be
1738 backwards compatible.
1740 * Send the ENDING packet with timeout in the backup resuming
1741 protocol. This is to assure that all routers has connected
1742 to the primary router. Affected file silcd/server_backup.c.
1744 * Changed the RNG to take the first IV from random data. It
1745 used to take it from zero actually. Changed the RNG also
1746 to use /dev/urandom during session. /dev/random is used
1747 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1749 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Changed the SILC packet header to have the first two bytes
1752 (the packet length) encrypted. Affected files aroung the
1753 code tree, lib/silccore/silcpacket.[ch]. Removed the
1754 SilcPacketCheckDecrypt callback. It is not needed anymore
1755 since the silc_packet_receive_process will determine now
1756 whether the packet is normal or special.
1758 * Implemented the unidirectional MAC keys. Affected files
1759 lib/silcske/silcske.c, silcd/protocol.c and
1760 lib/silcclient/protocol.c.
1762 * Implemented the packet sequence number to the MAC computation.
1763 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1764 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1765 lib/silcclient/protocol.c.
1767 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Allow backup router to announce servers. All servers
1770 announced by backup router are added to the global list
1771 automatically. Update hte server's socket to our primary
1772 router also when backup router announces a server.
1773 Affected file silcd/packet_receive.c.
1775 * Do not update the client->router in the function
1776 silc_server_udpate_clients_by_server if the client is on
1777 global list. We might fail to find any specific server
1778 for locally connected clients and local cell clients. They
1779 should still use the `from' and not `to' as client->router.
1780 This fixes backup router resuming protocol. Affected file
1781 silcd/server_util.c.
1783 * Decrease channel statistics count only if the channel
1784 deletion worked. Affected files are silcd/server.c and
1785 silcd/server_util.c.
1787 * Added silc_server_update_servers_by_server to update origin
1788 of all server entries. Used during backup router protocol.
1789 Affected files silcd/server_util.[ch], silcd/server.c. and
1790 silcd/backup_router.c.
1792 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1793 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1794 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1795 lib/silccrypt/silchmac.c.
1797 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Assure that router cannot reroute the same channel message
1800 to the sender. Affected file silcd/packet_receive.c.
1802 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Made better checks that the channel message is not sent
1805 to the router it came from. Affected file is
1806 silcd/packet_send.c. Fixed memory leak too.
1808 * Announce informations for incoming router connection, but
1809 only after checking if it is replaced by backup router.
1810 Affected file silcd/packet_receive.c.
1812 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Fixed the backup resuming protocol to work in multiple
1815 router environment. Affected file silcd/server_backup.c.
1817 * Route packet only to one router in the function
1818 silc_server_packet_send_to_channel. Affected file is
1819 silcd/packet_send.c.
1821 * Fixed silc_server_send_notify_dest to set the broadcast
1822 flag. Fixed the silc_server_send_notify_topic to actually
1823 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1824 Affected file silcd/packet_send.c.
1826 * Changed the SFTP Filesystem interface. Changed the
1827 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1828 the filesystem operation function. The SilcSFTPFilesystem
1829 is now a context that is allocated by all filesystem allocation
1830 functions and it already includes the operations structure
1831 and filesystem specific context. It is given as argument
1832 now to the silc_sftp_server_start. This made the interface
1833 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1834 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1836 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Changed the backup router adding and getting interfaces
1839 in the server. The router that will be replaced by the
1840 specified backup router is now sent as argument. Affected
1841 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1844 * Added silc_net_addr2bin_ne to return the binary form of
1845 the IP address in network byte order. Affected files
1846 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1848 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Check for existing server ID in silc_server_new_server
1851 and in silc_server_connect_to_router_final and remove the
1852 old entry if it exists. Affected file silcd/packet_receive.c,
1855 * Send the channel message always to only one router, either
1856 in upstream or downstream. Affected file is
1857 silcd/packet_send.c.
1859 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Wrote the definition of the backup resuming protocol to the
1862 protocol specification.
1864 * Removed one redundant channel key generation from normal
1865 server during joining procedure. Removed one redundant
1866 channel key sending from server to router during joining
1867 procedure. Affected file silcd/command.c.
1869 * Made minor bugfixes to the backup router resuming protocol.
1870 Affected file silcd/server_backup.c, server.c.
1872 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Added --disable-asm configuration option. Affected files
1875 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1878 * Implemented the backup resuming protocol that is used to
1879 resume the primary router position in the cell after the
1880 primary router comes back online. Affected files
1881 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1882 and silcd/server_util.[ch].
1884 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Sleep two (2) seconds after sending QUIT command to server.
1887 Affected file lib/silcclient/command.c.
1889 * Assure that if outgoing data buffer is pending do not force
1890 send any data. Affected file silcd/packet_send.c.
1892 * Assure that if outgoing data buffer is pending do not force
1893 send any data. Affected file lib/silcclient/client.c.
1895 * Implemented the backup router support when the primary router
1896 goes down. The servers and routers can now use the backup
1897 router as new primary router without loosing connectivity.
1899 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1901 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1902 in the server to indicate disabled entry. All data read
1903 from the connection will be ignored and no data is sent
1904 for entry that is disabled. Affected files are
1905 silcd/idlist.h, silcd/server.c.
1907 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Created SFTP client and server test programs in the
1910 lib/silcsftp/tests directory.
1912 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Implemented memory filesystem (virtual filesystem) for
1915 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1918 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1920 * Implemented the SFTP (SSH File Transfer Protocol) to the
1921 lib/silcsftp. It includes SFTP client and SFTP server
1924 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Moved lib/silccore/silcprotocol.[ch] to the
1927 lib/silcutil library.
1929 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1930 take variable argument list pointer as argument. Affected
1931 file lib/silcutil/silcbuffmt.[ch].
1933 * Added silc_buffer_set function that is used to set data
1934 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1935 Affected file lib/silcutil/silcbuffer.h.
1937 * Changed various routines in the core library to use the new
1938 silc_buffer_set instead of allocating new buffer only for
1941 * Added 64-bit value formatting and unformatting support to the
1942 silc_buffer_[un]format routines. Affected file is
1943 lib/silcutil/silcbuffmt.[ch].
1945 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1946 to includes/bitmove.h.
1948 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Fixed channel user mode saving in client library. Affected
1951 file lib/silcclient/command[_reply].c.
1953 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Defined the file transfer to the SILC Protocol. Added
1956 new packet type SILC_PACKET_FTP and defined File Transfer
1957 Payload. The mandatory file transfer protocol is SFTP
1958 (SSH File Transfer Protocol). Affected file in addition
1959 of the internet draft is lib/silccore/silcpacket.h.
1961 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1962 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1963 is used as part of backup router protocol when the primary
1964 router of the cell is back online and wishes to resume
1965 the position as primary router.
1967 * Redefined the MAC generation keys in the protocol. The
1968 same key is not used anymore in both direction. Both
1969 direction will now use different keys for sending and
1970 receiving. This fixes a potential security flaw. This
1971 change causes incompatibilities in the protocol.
1973 * Redefined also the MAC computation from the packet.
1974 An packet sequence number is now added to the MAC
1975 computation. This prevents possible replay attacks against
1976 the protocol. This change too causes incompatibilities
1979 Added `sequence' field to the SilcPacketContext to hold
1980 the current sequence number for the packet.
1982 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Added `created' field to the SilcIDListData in the file
1985 silcd/idlist.h to indicate the time when the entry was
1988 * Added `created' field to the SilcChannelEntry too. Affected
1989 file silcd/idlist.h.
1991 * Added `creation_time' aguments to all the announcement functions
1992 in the server. If it is provided then only the entries that
1993 was created after the provided time frame are actually
1994 announced. Affected file silcd/server.[ch].
1996 * The protocol says that the Channel ID's IP address must be
1997 based on the router's IP address. Added check for this in
1998 the silc_server_new_channel when processing incoming New Channel
1999 Payload. Affected file silcd/packet_receive.c.
2001 * Print out the correct version with --version in SILC client.
2002 Affected file irssi/src/silc/core/silc-core.c.
2004 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * Fixed WHOWAS command to check for completnes of the client
2007 entry always, not just when the command is coming from client.
2008 Affected file silcd/command.c.
2010 * Added new function silc_server_packet_queue_purge to purge the
2011 outgoing data queue to the network. After the function returns
2012 it is guaranteed that the outgoing packet queue is empty.
2013 Affected file silcd/packet_send.[ch].
2015 * Purge the outgoing packet queue in the rekey protocol's final
2016 callback to assure that all rekey packets go to the network
2017 before quitting the protocol. Affected file silcd/server.c.
2019 * Added silc_client_packet_queue_parse as similar function as
2020 in server to the client library. The affected file is
2021 lib/silcclient/client.c.
2023 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Splitted silcd/server.c and created silcd/server_util.[ch]
2026 for utility functions.
2028 * Added new socket flag SILC_SF_DISABLED to indicate that the
2029 connection is open but nothing can be sent to or received from
2030 the connection. Affected file lib/silcutil/silsockconn.[ch].
2031 The checking for disabled socket is checked in the low level
2032 silc_socket_write and silc_socket_read functions.
2034 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2036 * Allow only nicknames and channel names that fits into the
2037 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2039 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * When processing JOIN command reply in server check that if
2042 the channel exists in our global list we'll move it the local
2043 list. Affected file silcd/command_reply.c.
2045 * Fixed the check whether client is joined on the channel already
2046 in JOIN command. Affected file lib/silcclient/command.c.
2048 * Fixed the JOIN command reply to check whether the channel
2049 already exists. Affected file lib/silcclient/command_reply.c.
2051 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Added silc_ske_status_string to map the SKE error numbers
2054 to readable strings. The affected files are
2055 lib/silcske/silcske[_status].[ch].
2057 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Do not show the private channels on the WHOIS channel list
2060 as it is not allowed by the protocol. The affected file is
2063 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Assure that the packet length digged from the actual packet
2066 is something sensible in the silc_packet_decrypt_rest_special
2067 in lib/silccrypt/silcpacket.c.
2069 * Free and NULL the allocated pointer in silc_hmac_alloc if
2070 the HMAC allocation fails. The affected file is
2071 lib/silccrypt/silchmac.c.
2073 * Print the selected security properties to the log files in
2074 the server. Affected file silcd/protocol.c.
2076 * Add SKE's reference counter even if calling the completion
2077 callback manually. Otherwise it goes negative, although it
2078 does not cause any problems. The affected file is
2079 lib/silcske/silcske.c.
2081 * Remove the client entry with short timeout after giving the
2082 KILL command. Affected file lib/silcclient/command.c.
2084 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2085 case all found clients are already disconnected (WHOWAS would
2086 found them) in the server. Affected file silcd/command.c.
2088 * Update the last_receive (time of last data received) to be
2089 updated only when received private or channel message so that
2090 the idle time showed in WHOIS makes more sense.
2092 * Added boolean field `valid' in to the SilcClientEntry in the
2093 client library to indicate whether the entry is valid or not.
2094 This fixes the nickname change bug on channel when changing
2095 the nickname to be same than the old (like nick to Nick) the
2096 nickname formatter doesn't set the new nick anymore to Nick@host.
2097 Affected file lib/silcclient/idlist.[ch].
2099 * Now actually fixed the nickname changing on disconnection.
2100 Added new function silc_change_nick to the Irssi SILC Client.
2101 Affected file irssi/src/silc/core/client_ops.c,
2102 irssi/src/silc/core/silc-nicklist.[ch].
2104 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2106 * Check that the public key exists in the GETKEY command before
2107 trying to encode it. Affected file silcd/command.c.
2109 * Print some notifications on received public keys with GETKEY
2110 command in the Irssi SILC Client. Affected files are
2111 irssi/src/fe-common/silc/module-formats.[ch],
2112 irssi/src/silc/core/client_ops.c.
2114 * Use IDENTIFY command to resolve the server information in the
2115 GETKEY command instead of INFO command. Affected file
2116 lib/silcclient/command.c.
2118 * All command reply functions in the client library now calls
2119 the pending command reply callbacks even if an error has
2120 occurred. The server has done this a long time and now it was
2121 time to move the client library to this as well. Now all
2122 errors can be delivered back to the pending command reply
2123 callbacks if necessary. Affected files are
2124 lib/silcclient/command[_reply].[ch].
2126 * Change the nickname on disconnection back to the username
2127 because in reconnect the server will enforce it to it anyway.
2128 Affected file irssi/src/silc/core/silc-servers.c.
2130 * Fixed a config file parsing bug in the Irssi SILC client.
2131 Affected file irssi/src/silc/core/clientconfig.c.
2133 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * When printing the channel mode on JOIN, verify that the
2136 channel key and channel's HMAC are valid. Affected file
2137 irssi/src/silc/core/client_ops.c.
2139 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2142 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2143 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2145 * Removed channel key rekey task deleting from the function
2146 silc_server_save_channel_key. Affected file silcd/server.c.
2147 Added explicit timeout task context instead that is used to
2148 delete the task if we are registering a new task before the
2149 new task has elapsed.
2151 * When channel key rekey occurs the client library now saves
2152 the old channel key for a short period of time (10 seconds) and
2153 is able to use it in case some is still sending channel
2154 messages encrypted with the old key after the rekey. Affected
2155 file lib/silcclient/[idlist.h|client_channel.c].
2157 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2159 * Added check to the silc_server_new_id_real to not accept
2160 new ID if it is the sender's own ID. Affected file is
2161 silcd/packet_receive.c.
2163 * Assure that we do not announce ourself or the one we've
2164 sending our announcements when we're router and are announcing
2165 servers to our primary router. Affected file silcd/server.c.
2167 * Fixed silc_server_command_identify_check_client to assemble
2168 correct WHOIS packet. It send corrupted WHOIS packet and
2169 caused problem with router to router connections. Affected
2170 file silcd/command.c.
2172 Fixed also silc_server_command_whois_check the same way
2173 as for the IDENTIFY command.
2175 * Added new SilcIDListStatus to the server in the SilcIDListData
2176 structure. The status now includes the current status of
2177 the entry (like registered, resolved etc.). Affected file
2178 silcd/idlist.[ch]. Defined a bunch of different status types
2179 as well. This replaced the old boolean registered field as well.
2181 Added resolve_cmd_ident field to the SilcClientEntry structure
2182 too so that if the entry is for example being resolved so
2183 another command may attach to the same pending command reply
2184 without requiring to resolve the same entry again. This concept
2185 should optimize the WHOIS and the IDENTIFY resolving under
2186 heavy load by taking away unnecessary resolving for entries
2187 that are being resolved already.
2189 Added support for adding multiple pending commands for one
2190 command idenfier. Affected file silcd/command[_reply].[ch].
2192 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2193 before deleting the data. Otherwise the hash table will have
2194 freed data in comparison functions. Affected file is
2195 silcd/command_reply.c.
2197 * Fixed silc_idlist_replace_client_id to add the new entry to
2198 the cache with NULL nickname. Otherwise there will be invalid
2199 memory as the nickname after the nickname is freed. Affected
2200 file silcd/packet_receive.c.
2202 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2203 saved into wrong slots because the previous number of entries
2204 was not taken into account. Affected file silcd/idlist.c.
2205 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2207 * If we are router and we receive JOIN notify to a channel that
2208 does not have any users then notified client is marked as the
2209 channel founder, as it is it. The affected file is
2210 silcd/packet_receive.c
2212 * Added to the extended hash table API's table_del_*ext functions
2213 the destructor as argument too, so that the caller can decide
2214 which destructor to use or whether to use destructor at all.
2215 Affected file lib/silcutil/silchashtable.[ch].
2217 * Fixed ID Cache purging. It actually deleted the entries from
2218 the hash table after the data was freed. The hash table ended
2219 up comparing freed memory. The affected file is
2220 lib/silccore/silcidcache.c.
2222 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Fixed Irssi SILC client's KILL command's HELP syntax.
2226 * The USERS command now resolves the detailed user information
2227 if the userinfo field is missing. Affected file is
2228 lib/silcclient/command_reply.c.
2230 * Do not print error in silc_file_read if the read file does
2231 not exist. Just silently return NULL. Affected file is
2232 lib/silcutil/silcutil.c.
2234 * Fixed the silc_log_output to not wine about NULL filename
2235 and to not create some bogus " " filename. Affected file is
2236 lib/silcutil/silclog.c.
2238 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Fixed various printing bugs on the user interface in the
2241 Irssi SILC Client. Minor changes that were forgotten from
2244 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Fixed the configure.in.pre and the compilation and distribution
2247 environment to support the new autoconf 2.52. That version is
2248 now required to compile the CVS trunk.
2250 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2252 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2253 to generally parse user@fqdn format strings. Affected file
2254 lib/silcutil/silcutil.c.
2256 * Added nickname_format and nickname_force_format fields to the
2257 SilcClientParams structure. The first one defines the format
2258 for the nicknames that the library will enforce if the receives
2259 multiple same nicknames. The second one is boolean value and
2260 can be used to force the library to always enforce the format
2261 to the nicknames regardles whether there are multiple nicknames
2262 or not. This configurable formatting was employed to flexibly
2263 support accessing multiple nicknames from the user interface.
2264 The userinterface can now set the nicknames to what ever format
2265 they prefer. Affected file lib/silcclient/silcapi.h.
2267 Added function silc_client_nickname_format to the file
2268 lib/silcclient/idlist.c. It performs the nickname formatting.
2270 Added new field `hostname´ to the SilcClientEntry context.
2271 It holds the hostname of the client. Affected file is
2272 lib/silcclient/idlist.h.
2274 * Irssi SILC Client sets the nicknames in nick@hostn format.
2275 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2276 irssi/src/silc/core/silc-core.c.
2278 The WHOIS printing now also shows both the real nickname and
2279 the formatted nickname so that user knows how to access the
2280 user if there are multiple same nicknames cached. Affected
2281 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2282 printing formatting too to take the hostname now as a separate
2283 argument. The Affected file is
2284 irssi/src/fe-common/silc/modules-formats.[ch].
2286 * Changed the silc_client_get_clients_local to accept the formatted
2287 nickname as argument. It accepts the real nickname too but the
2288 formatted nickname can be used to find the true entry from
2289 multiple entries. Affected file lib/silcclient/silcapi.h and
2290 lib/silcclient/idlist.c.
2292 * Added nickname_format_parse field to the SilcClientParams.
2293 It is a callback function provided by the application to parse
2294 the nickname out of the formatted nickname string. The library
2295 calls it to get the nickname from the formatted string. Since
2296 the application generally knows better the format of the nickname
2297 string it parses it instead of the library, even though library
2298 encodes the formatted string. If the callback function is not
2299 provided then the library will use the string as is. The
2300 affected file is lib/silcclient/silcapi.h.
2302 * All the nickname strings passed to the client library in
2303 commands are now expected to be formatted nickname strings.
2304 If the command does not support the formatted nickname string
2305 it will assume that the sent string is the actual nickname.
2306 Affected file lib/silcclient/command.c.
2308 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Added public key authentication support to OPER and SILCOPER
2311 commands in the client library. Affected file is
2312 lib/silcclient/command.c.
2314 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Changed the get_auth_methdod client operation to be asynchronous.
2317 It can be async if the application resolves the authentication
2318 method from the server during the negotiation. Added new
2319 SilcGetAuthMeth completion callback that the application will
2320 call after resolving the authentication method.
2322 Added function silc_client_request_authentication_method that
2323 the application can use to resolve the authentication method
2324 from the server. Added also SilcConnectionAuthRequest callback
2325 that the library will call after the server has replied. The
2326 application can call this function if it does not know the
2327 current authentication method.
2329 Affected files are lib/silcclient/client.c and
2330 lib/silcclient/silcapi.h.
2332 * The Irssi SILC client now automatically resolves the authentication
2333 method incase any configuration information is not present (and
2334 currently there never is). The affected file is
2335 irssi/src/silc/core/client_ops.c.
2337 * Fixed public key authentication from the client library.
2338 Affected file lib/silcclient/protocol.c. Changed also the
2339 protocol specification about the public key authentication in
2340 the connection authentication protocol. The actual data to be
2341 signed is now computed with a hash function before signing.
2343 * Fixed the public key authentication from the server as well.
2344 Affected file silcd/protocol.c.
2346 * Removed the mlock()'s from the memory allocation routines.
2347 Affected file lib/silcutil/silcmemory.c. The ./configure does
2348 not check anymore for the mlock(). Affected file is
2351 * Fixed USERS command in server to allow the execution of the
2352 command for private and secret channels if the client sending
2353 the command is on the channel. Affected file silcd/command.c.
2355 * Fixed silc_client_get_clients_local to return the clients
2356 count correctly. It could return wrong value. Affected file
2357 lib/silcclient/idlist.c.
2359 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2362 types. The assembler optimizations seemed not to like 64-bit
2363 data types. The assmebler optimizations thus are now enabled
2364 also for BSD systems as opposed to only enable them for Linux.
2366 * Do not check for threads at all on BSD systems. Affected
2367 file configure.in.pre.
2369 * Removed -n and -h options from the Irssi SILC Client since
2370 they are not used in silc.
2372 * Fixed the prime generation to assure that the first digit
2373 of the generated random number is not zero since our conversion
2374 routines does not like number strings that starts with zero
2375 digit. If zero digit is seen the random number is regenerated.
2376 This caused some corrupted RSA keys when the zero first digit
2377 was met. Affected file lib/silcmath/silcprimegen.c.
2379 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Fixed WIN32 configuration in the ./configure script.
2382 Fixed to include xti.h on environments that has it.
2383 Patches by Carsten Ilchmann and andrew.
2385 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Changed the silc_id_create_client_id to be collision
2388 resistant. It is now assured that there cannot be created
2389 two same client ID's. I suspect that some weird bugs in
2390 the server were actually caused by duplicate Client IDs.
2391 Affected file silcd/serverid.[ch]. A router receiving
2392 new ID now also assures and informs the sending server
2393 if the ID caused collision.
2395 * Changed the silc_id_create_channel_id to also assure that
2396 there are no collisions.
2398 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Statement about ignoring the Mutual Authentication flag when
2401 performing rekey with PFS was a bit misleading. It is ignored
2402 if it was set in the initial negotiation, it cannot be even
2403 set in the rekey. Fixed in the ke-auth draft. Started the
2404 new versions of the protocol drafts in the doc/.
2406 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Fixed a bug in silc_client_command_identify_save when saving
2409 new channel information. The channel name was no duplicated
2410 and caused crash on exit. Affected file is
2411 lib/silcclient/command_reply.c.
2413 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2415 * Fixed the getkey command handling in the server. Send just
2416 empty OK reply to the sender if the key could not be fetched
2417 (but everything else was ok, like the key just was not available).
2418 Changed the public key parameter to optional in the protocol
2419 specs so that empty OK reply can be sent. Affected file
2422 Added a message to Irssi SILC client to tell to user if the
2423 server did not return a public key.
2425 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Fixed a channel key regeneration bug. It registered new
2428 timeout tasks exponentially until all system resources were
2429 used. Affected file silcd/server.c.
2431 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Added the SILC Document generator to the scripts/silcdoc.
2434 It can be used to generate the Toolkit Reference Manual out
2435 of the source tree. Internally it will also use the RoboDoc
2436 generator now imported in util/robodoc.
2438 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Added couple of return's in rekey protocol if error orccurred
2441 during the protocol. The execution must be terminated.
2442 Affected file silcd/protocol.c. Also, terminate the protocol
2443 always with timeout.
2445 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * The client's Client ID was created initally from the wrong
2448 nickname (it could have been in format nick@host) in the
2449 silc_server_new_client. Affected file silcd/packet_receive.c
2451 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Added some SILC_LOG_ERROR's to various error conditions
2454 if client could not be added to ID cache. Affected files
2455 silcd/packet_receive.c and silcd/server.c.
2457 * When client's sock->user_data is freed, NULL also the
2458 client->router and client->connection pointers. Added check
2459 for these pointers being NULL to various places around the
2460 code. Affected file silcd/server.c.
2462 * Added client->data.registered == TRUE checks to various
2463 places around the code to assure that unregistered client's
2464 are not handled when it is not allowed. Affected file
2467 * Added `bool registered' fields to all
2468 silc_idlist_[server|client]_get_* routines to indicate whether
2469 the fetched client needs to be registered or not. Affected
2470 file silcd/idlist.[ch].
2472 * Add your own entry as registered to the ID cache in the
2473 server. Affected file server.c.
2475 * Fixed a bug in silc_server_new_server. The SilcServer was
2476 set as the new server's context instead of SilcServerEntry.
2477 This naturally caused some weird bugs.
2479 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Do not delete the channel rekey task when adding it
2482 for in silc_server_create_channel_key.
2484 * Changed the silc_server_create_channel_key to return
2485 TRUE or FALSE to indicate the success of the channel key
2488 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Fixed MSVC++ project files and added missing files to
2491 Makefiles under win32/.
2493 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Do not add TCP_NODELAY flag if the operating system
2496 does not have it defined. Affected files are
2497 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2499 * Fixed buffer overflow from Irssi SILC Client. Affected
2500 file irssi/src/fe-common/core/themes.c.
2502 * Fixed double free in client library in the file
2503 lib/silcclient/client.c when disconnecting from server.
2505 * Applied double free patch from cras to Irssi SILC client.
2506 Affected files irssi/src/core/[modules/expandos].c
2508 * Fixed the disconnection handling to Irssi SILC Client.
2509 The application must call silc_client_close_connection
2510 in ops->connect client operation in case of failure of
2511 the connection. Affected file is
2512 irssi/src/silc/core/client_ops.c.
2514 * Do not set sock->protocol to NULL in the function
2515 silc_client_close_connection after executing the protocol's
2516 final callback since the sock might not be valid anymore.
2517 Affected file lib/silcclient/client.c.
2519 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2521 * Do not enable SILC_THREADS if the linking with libpthread
2522 did not happen. Affected file configure.in.pre.
2524 * Added notion to protocol specification that server must
2525 verify the sent authentication payload with CMODE when
2526 setting the channel founder key. Implemented it to the
2527 server. Affected file silcd/command.c.
2529 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Added _EXTRA_DIST SILC distribution variable to the
2532 distributions file. It is used to conditionally add extra
2533 files or directories to the specific distribution. Affected
2534 files ./prepare, Makefile.am.pre and distributions.
2536 Removed the `_' from the start of the distribution names.
2539 * Added README.WIN32 for instructions to compile the Toolkit
2542 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Fixed a double free in disconnection in the server. Affected
2545 file is silcd/server.c.
2547 * Fixed the lib/silcske/groups.c to work now also with GMP
2548 MP library. The string conversion did not work when using
2549 specific base and the base is indicated in the string as well.
2551 * Created win32/ directory which now includes MSVC++ specific
2552 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2553 It will appear only in the toolkit distribution
2555 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2557 * Changed the key material distribution function in case when
2558 the hash output is too short. The data is now concatenated
2559 a bit differently than it used to. Made the change to the
2560 SKE protocol specification.
2562 * Added better GMP detection to configure.in.pre. A patch
2565 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Fixed a minor bug in SKE that might cause some problem on
2568 some platforms. Affected file lib/silcske/silcske.c.
2570 * Added the cookie checking for initiator in the SKE. It checks
2571 that the responder returns the sent cookie unmodified. The
2572 affected file is lib/silcske/silcske.c. Added new SKE
2573 error type INVALID_COOKIE that can be sent during the
2574 negotiation. Fixed some memory leaks as well.
2576 * Added the "invalid cookie" error message to Irssi SILC client's
2579 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Added `task_max' field to the SilcClientParams to indicate
2582 the maximum tasks the scheduler can handle. If set to zero,
2583 default values are used. Affected file lib/silcclient/silcapi.h.
2585 * Fixed memory leaks in silc_client_close_connection. Affected
2586 file lib/silcclient/client.c.
2588 * Added silc_client_del_client_entry to client library to free
2589 all memory of given client entry. Affected file is
2590 lib/silcclient/idlist.[ch].
2592 * Added new functions silc_client_del_channel and
2593 silc_client_del_server to delete channel and server entries.
2594 Affected file lib/silcclient/[silcapi.h/idlist.c].
2596 * Removed silc_client_del_client_by_id from silcapi.h.
2598 * Fixed the INFO command to return the server's own info
2599 correctly when querying by Server ID. Affected file is
2602 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2604 * Removed the non-blocking settings in WIN32 code in the
2605 silc_sock_[read/write] and added SleepEx instead. Affected
2606 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2607 of input data is now checked with FIONREAD and ioctlsocket.
2609 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Call silc_schedule_task_del_by_context in the
2612 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2613 Affected file lib/silccore/silcprotocol.c.
2615 * Call silc_protocol_cancel for active protocols in the
2616 silc_server_close_connection if the funtion
2617 silc_server_free_sock_user_data has not been called.
2618 Affected file silcd/server.c.
2620 * Generic tasks cannot be deleted using the del_by_fd
2621 task deleting function since generic tasks does not match
2622 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2624 * Added a notion to SILCOPER help file that the SILCOPER works
2625 only on router server, not on normal server.
2627 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Added for WIN32 support for the new scheduler as well.
2630 Affected file lib/silcutil/win32/silcwin32schedule.c.
2632 * Fixed the SHA1 implementation to work on various platforms.
2634 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2637 API. It is part of the scheduler now. Everything else is
2638 as previously but some functions has changed their names.
2639 Checkout the lib/silcutil/silcschedule.h for the interface.
2640 Updated all applications to use the new interface. Affected
2641 files are lib/silcutil/silcschedule.[ch].
2643 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2645 * Found a bug in the SKE implementation. The HASH value,
2646 specified by the protocol, was not computed correctly. The
2647 public key of the responder was not added to the computation
2648 even though it is mandatory. Affected file lib/silcske/silcske.c.
2649 This unfortunately causes incompatibilities with older
2650 clients and servers.
2652 * Added WIN32 specific network init and uninit functions:
2653 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2654 the Winsock2. Affected file lib/silcutil/silcnet.h and
2655 lib/silcutil/win32/silcwin32net.c.
2657 * Set the socket always to nonblocking mode on WIN32 after
2658 reading data or writing data. Affected file is
2659 lib/silcutil/win32/silcwin32sockconn.c.
2661 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Fixed various compilation problems under WIN32. Affected
2664 files lib/silcutil/win32/silcwin32thread.c and
2665 lib/silcutil/win32/silcwin32schedule.c.
2667 * Removed all _internal.h #includes from public header
2668 files. Internal headers must never be included from
2671 Removed also the lib/silcske/payload_internal.h file.
2673 * All include files that may be needed (public and some others
2674 included by the public headers) by application developers are
2675 now copied to the ./includes directory. It does not copy any
2676 internal headers. Affected file Makefile.defines.pre and all
2677 Makefile.am's under lib/ and subdirs.
2679 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Do not change the ~/.silc directory's permissions automatically.
2682 Affected file irssi/src/silc/core/clientutil.c.
2684 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Do not cancel the protocol in silc_server_close_connection
2687 it might cause recursion. Now cancelled in the function
2688 silc_server_free_sock_user_data. Affected file silcd/server.c.
2690 * Fixed the silc_server_remove_clients_by_server to regenerate
2691 the channel keys correctly finally. Added also new function
2692 silc_server_remove_clients_channels to actually do it.
2693 Affected file silcd/server.c.
2695 * Fixed the silc_server_new_channel to not crash by giving
2696 wrong router to the new channel. Affected file is
2697 silcd/packet_receive.c.
2699 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2701 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2702 which is given as argument to the silc_client_alloc now.
2703 It can be used to configure the client and set various parameters
2704 that affect the function of the client.
2706 * The USERS command in server did not check whether the channel
2707 is private or secret. Affected file silcd/command.c.
2709 * Added new argument to the USERS command in protocol specification.
2710 The USERS command now can take the channel name as argument
2711 as well. Added support for this in client and server and
2712 updated the protocol specs.
2714 * Completed the GETKEY command in client. It can be now used
2715 to fetch also servers public key not only some clients.
2716 Affected files lib/silcclient/command[_reply].c.
2718 * Added silc_client_get_server to return server entry by the
2719 server name. Affected files lib/silcclient/silcapi.h and
2722 * Redefined the IDENTIFY command in protocol specification to be
2723 more generic. It now can be used to query information about
2724 any entity in the SILC Network, including clients, servers and
2725 channels. The query may be based either the entity's name
2726 or the ID. Added support for this in both client and server.
2728 Affected files silcd/command.c and lib/silcclient/command.c
2729 and command_reply.c.
2731 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2732 the _from_client and _from_server functions. Affected file
2735 * Added silc_client_get_channel_by_id_resolve to the file
2736 lib/silcclient/silcapi.h to resolve channel information by
2737 its ID. Added also silc_client_get_channel_by_id that
2738 does not resolve it from the server.
2740 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Added SilcServerEntry context into the client library
2743 to represent one server. The INFO command now allocates
2744 these to save the resolved server info. For now on the
2745 client library will also keep information about servers,
2746 connected and resolved with INFO.
2748 The INFO command now allocates the SilcServerEntry context
2749 and saves the server info there. The COMMAND_REPLY in
2750 the INFO now returns the parameters to application in
2751 same order as defined in the protocol specification.
2753 The entries are cached in the client->server_cache.
2755 * The INFO command is now issued after received the Client ID
2756 from the server. Affected file lib/silcclient/client.c.
2758 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2759 to the application as the mode changer might be server.
2760 It is guaranteed that NULL is not returned anymore to the
2761 application. Affected file lib/silcclient/client_notify.c.
2763 The ID Type is now also passed to the application so that
2764 it can check whether the returned entry is SilcClientEntry
2767 Added new function silc_client_get_server_by_id to return
2768 the server entry by ID. Affected files are the
2769 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2771 * Do not create the channel in the Irssi SILC Client when issuing
2772 the JOIN command but when received the sucessful JOIN command
2773 reply. Otherwise the channel might get created even though we
2774 could not join it. The Affected file is
2775 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2777 * Fixed a channel joining bug in router. The router must also
2778 check the channel modes, invite and ban lists etc. when serving
2779 the JOIN command sent by normal server. Affected file is
2780 silcd/command.c. The router now resolves the client's
2781 information from the server who sent the JOIN command if it
2782 does not know it, and processes the JOIN command only after
2785 * Changed the SilcCommandCb to take new argument; void *context2.
2786 Affected file lib/silccore/silccommand.h
2788 The second argument in the command callbacks in the server now
2789 includes the SilcServerCommandReplyContext if the command was
2790 called as pending command callback from the command reply.
2791 Otherwise it is NULL. When called as pending the status of the
2792 command reply will be checked and if it was erronous the
2793 error will be sent to the original sender of the command.
2794 This way the client always receives the error messages even
2795 though the server was actually the one who received the error
2796 when it resent the command to router, for example. Affected
2797 files silcd/command[_reply].[ch].
2799 * Fixed sending WHOWAS command's error message to client if
2800 the requested client could not be found. It was missing.
2803 * Changed the CMODE and CUMODE commands reply arguments in the
2804 protocol specification. The Channel ID is now sent in both
2805 of the commands to identify the channel. Implemented this
2806 new feature to the client and server. Affected files
2807 lib/silcclient/command_reply.c and silcd/command.c.
2809 * Made better checks for invite and ban lists in the JOIN
2810 command in server. Affected file silcd/command.c.
2812 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * The server now performs the incoming host IP/DNS lookup
2815 using the silc_socket_host_lookup and thus does not block
2816 the server anymore. Affected file silcd/server.c.
2818 * Completed the multi-thread support for SILC Scheduler in
2819 the lib/silcutil/silcschedule.c.
2821 * Fixed the configure.in.pre to detect the pthread correctly
2824 * Fixed a deadlock in silc_task_queue_wakeup in the file
2825 lib/silcutil/silctask.c.
2827 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Added new function silc_schedule_wakeup that is used in
2830 multi-threaded environment to wakeup the main thread's
2831 schduler. It needs to be used when a thread adds a new task
2832 or removes a task from task queues. After waking up, the
2833 scheduler will detect the task queue changes. If threads
2834 support is not compiled in this function has no effect.
2835 Implemented the wakeup mechanism to both Unix and WIN32
2836 systems. Affected files are lib/silcutil/silcschedule.[ch],
2837 lib/silcutil/unix/silcunixschedule.c and the
2838 lib/silcutil/win32/silcwin32schedule.c.
2840 * Added new function silc_task_queue_wakeup to wakeup the
2841 scheduler by the specified task queue. Affected file
2842 lib/silcutil/silctask.[ch].
2844 * The silc_socket_host_lookup_start now wakes up the scheduler
2845 after adding the timeout task. Affected file is
2846 lib/silcutil/silcsockconn.c.
2848 * The silc_socket_host_lookup is synchronous now if the threads
2849 support is not compiled in. However, the callback is still
2850 called asyncronously through the scheduler, anyway. Affected
2851 file lib/silcutil/silcsockconn.c.
2853 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Added new function silc_socket_host_lookup to perform
2856 asynchronous IP and FQDN lookups for the socket connection.
2857 Affected files lib/silcutil/silcsockconn.[ch].
2859 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2862 that may or may not compile the mutex support in.
2864 Changed the silc_mutex_alloc interface. It allocates the
2865 mutex now to the sent pointer and returns TRUE or FALSE.
2867 Affected file lib/silcutil/silcmutex.h.
2869 * Wrote the SILC Task Queue interface to support multi-threads.
2870 Affected file lib/silcutil/silctask.[ch].
2872 * Wrote the SILC Scheduler to support multi-threads. Affected
2873 file lib/silcutil/silcschedule.c.
2875 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2878 in lib/silcutil/win32/.
2880 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Defined SILC Mutex API and SILC Thread API and implemented
2883 them for Unix. Affected files are
2884 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2885 lib/silcutil/unix/silcunixmutex.c and
2886 lib/silcutil/unix/silcunixthread.c.
2888 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Fixed the silc_server_remove_clients_by_server's channel
2891 key re-generation. The hash table handling was incorrect
2892 and would not work with many channels. Affected file is
2895 * Fixed some memory leaks around the server code.
2897 * Rewrote the silc_server_get_users_on_channel to support IPv6
2898 based Client ID's. Affected file silcd/server.c.
2900 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2901 specification. However, a separate document must be written
2902 to define the detailed signing procedure and the payload
2903 associated with the flag. Defined the flag to the
2904 lib/silccore/silcchannel.h as well.
2906 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Changed the dynamic tables to static size tables in the
2909 lib/silccrypt/silchmac.c.
2911 * Removed GCC dependencies from the code. A patch by cras.
2913 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Do not show the error "Error receiving packet bla bla"
2916 in server if it really was not an error (-2 means that reading
2917 is pending). Affected file silcd/server.c.
2919 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Fixed a possible crash in silc_server_remove_clients_by_server
2922 in silcd/server.c. Fixed there also some memory leaks.
2924 * Fixed the silc_idlist_replace_client_id. It could replace
2925 wrong key in the hash table. Affected file silcd/idlist.c.
2927 * Do not check whether there are global users on the channel
2928 if the channel->global_users is FALSE. Affected functions
2929 silc_server_remove_from_one_channel and
2930 silc_server_remove_from_channels in silcd/server.c. Also,
2931 do not check if the removed client is local as we can be
2932 sure that global client was not removed from the channel
2933 and checking for global users is not needed.
2935 * The silc_server_remove_clients_by_server now re-generates
2936 the channel keys correctly for those channels that had
2937 clients removed from them. Affected file silcd/server.c.
2939 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Found the reason of random crashes in the server. We weren't
2942 ignoring the SIGPIPE signal (which can be sent in write())
2943 and it crashed the server. Affected file silcd/silcd.c.
2945 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2947 * Assure that sock->user_data is not NULL in the function
2948 silc_server_packet_send in silcd/packet_send.c.
2950 * Disconnect the remote connection if it could not be added
2951 to any ID lists in the server. The affected file is
2954 * Check in silc_server_packet_send[_real/dest] that the
2955 socket is not disconnecting and ignore the data if it is.
2956 Affected file silcd/packet_send.c.
2958 * Define inline to __inline on native WIN32 compilation.
2959 Affected file includes/silcwin32.h.
2961 * Added some explicit type casts for inline code since MSVC
2962 require them. Affected files lib/silcutil/silcbuffer.h,
2963 lib/trq/silcdlist.h and lib/trq/silclist.h.
2965 * Print warning in log files from now on if the packet
2966 decryption fails. Affected file silcd/server.c.
2968 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Changed the `say' client operation's interface to accept
2971 new `type' argument to indicate the type of the message sent
2972 by the library. The application may filter the library's
2973 messages according the type. The affected file is the
2974 lib/silcclient/silcapi.h.
2976 * Added two new functions to lib/silcclient/silcapi.h:
2977 silc_client_del_client and silc_client_del_client_by_id.
2978 Affected file lib/silcclient/idlist.c.
2980 * Moved the clientincludes.h from includes/ to silc/ and
2981 serverincludes.h from includes/ to silcd/.
2983 * The modes for the CMODE and CUMODE are now passed as
2984 uint32 for application with COMMAND_REPLY. The affected
2985 file is lib/silcclient/command_reply.c.
2987 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * /WHOIS without arguments shows client's own information.
2990 Affected file lib/silcclient/command.c.
2992 * Changed PING to not accept any arguments. The specs
2993 says that client can ping only the connected server so
2994 requiring an argument is not needed. Affected file is
2995 lib/silcclient/command.c.
2997 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Fixed a fatal bug in private message sending and reception
3000 encryption and decryption when using private message keys.
3001 The implementation was incorrect and did not follow the
3002 specification. It causd that some of the message were
3003 lost since it did not use the sending and receiving keys
3004 as the protocol suggests. This has been fixed and will cause
3005 incompatibilities with older clients when sending private
3006 message encrypted with private message keys. Affected files
3007 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3008 and various other in Irssi SILC Client.
3010 Added `responder' boolean argument to the functions
3011 silc_client_add_private_message_key[_ske] to indicate when
3012 the key is added as responder or initiator of the key
3015 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Removed the silc_ske_check_version function and created
3018 a SilcSKECheckVersion callback. Added also a function
3019 silc_ske_set_callbacks that is now used to set all SKE
3020 callbacks. The callback functions are not given to
3021 the SKE functions anymore, but this function is used to
3024 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3026 * Added `silc_version' argument to the silc_client_alloc
3027 to define the version of the application for the library.
3028 The library will use the version string to compare it
3029 against the remote host's (usually a server) version
3030 string. Affected file lib/silcclient/silcapi.h
3032 * Added the KE protocol context to Key Agreement context
3033 in client library so that we can abort the SKE if it
3034 is in process when we get timeout. Affected file is
3035 lib/silcclient/client_keyagr.c.
3037 * Do not resolve the client ID forever if it returns in the
3038 first time that such client does not exist. This was done
3039 for example with private message. Affected file is
3040 lib/silcclient/client_prvmsg.c.
3042 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * Do not add regex.h for WIN32. The affected file
3045 includes/silcincludes.h.
3047 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3048 not work yet 100%. It generates the DLL's automatically
3049 when compiling with --with-win32 under cygwin.
3051 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * lib/contrib/regex.c is not compiled on WIN32.
3055 * Added silc_net_get_socket_opt function to the
3056 lib/silcutil/silcnet.h.
3058 * Added includes/silcwin32.h for WIN32 specific includes
3061 * Do not use ptime structure or any of the posix process
3062 functions on WIN32 in lib/silccrypt/silrng.c.
3064 * Added silc_gettimeofday to provide generic function
3065 for struct timeval on all platforms. Added the function
3066 to lib/silcutil/silcutil.h.
3068 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3071 library as they clearly belong there. As a plus side we
3072 can make the actual socket connection routines platform
3075 Added also new generic function silc_socket_read and
3076 silc_socket_write (that used to be silc_packet_[read/write].
3077 The implementation of these are platform specific.
3079 * Added WIN32 specific routines of silc_socket_[read/write]
3080 to lib/silcutil/win32/silcwin32sockconn.c.
3082 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Added preliminary support for native WIN32 compilation under
3085 cygwin (using the -mno-cygwin option for GCC) to the
3086 ./configure.in.pre. The --with-win32 now prepares the
3087 compilation for native WIN32.
3089 * Rewrote the SILC Scheduler interface in the file
3090 lib/silcutil/silcschedule.h. The scheduler is now context
3091 based and does not have anymore any global static scheduler.
3092 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3093 and created lib/silcutil/win32 directory for WIN32 based
3096 * Added Unix specific network routines to the
3097 lib/silcutil/unix/silcunixnet.c and the old
3098 lib/silcutil/silcnet.c includes now only generic routines.
3100 Added WIN32 specific network routines to the
3101 lib/silcutil/win32/silcwin32net.c.
3103 * Added Unix specific utility functions from the
3104 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3106 * Added WIN32 SILC Scheduler to the file
3107 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3110 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Do not handle JOIN notify in the server if the target client
3113 is not registered (idata->registered == FALSE). The affected
3114 file is silcd/packet_receive.c.
3116 * Update the nickrec->founder in event_cumode in the Irssi SILC
3117 client. Affected file irssi/src/silc/core/silc-channels.c.
3119 * Fixed the CUMODE_CHANGE notify handling in the server when
3120 server and router are announcing their clients on channels.
3121 Now the mode changes are saved and notified correctly. The
3122 affected file is /silcd/packet_receive.c.
3124 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3125 They really did not replace the cache entry in the ID Cache.
3126 Now they do that. Affected file silcd/idlist.c.
3128 * Fixed the KICK notify handling in the Irssi SILC client to
3129 update the channel records so that the kicked client does not
3130 appear to be on the channel. The affected file is
3131 irssi/src/silc/core/silc-channels.c.
3133 * Always update the conn->current_channel when executing command
3134 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3136 * Fixed the KILL notify handling in Irssi SILC client to remove
3137 the killed client on all channels.
3139 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Fixed the silc_parse_command_line to remove extra spaces
3142 from the start and end of the arguments. Affected file is
3143 lib/silcutil/silcutil.c.
3145 * Cancel and free any active protocol in the function
3146 silc_server_close_connection. Affected file silcd/server.c.
3148 * Cancel and free any active protocol in the function
3149 silc_client_close_connction. Affected file is
3150 lib/silcclient/client.c.
3152 * Do not execute the KILL command for clients that are in
3153 history (ie. they are not in the network). Affected file is
3156 * Fixed KILL notify handling, client does not crash anymore.
3157 Affected file irssi/src/silc/core/silc-channels.c.
3159 * Reduced the default packet buffer size from 2048 to 1024 in
3160 lib/silccore/silcpacket.c.
3162 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3163 counter to the SKE context that is incresed when the SKE library
3164 performs async operation outside the library. If the outside
3165 process frees the SKE context and FREED status will be set
3166 and the library will detect after the sync operation that the
3167 libary is freed. The affected files are
3168 lib/silcske/silcske[_status].[ch].
3170 * Resolve the client entry information in the function
3171 silc_client_channel_message to assure that NULL pointer is not
3172 passed as client entry to the application. */
3174 * Fixed the task timeout calculation to assure that there is
3175 never negative timeouts. The affected file is
3176 lib/silcutil/silcschedule.c.
3178 * Fixed the channel user mode notification sending in server.
3179 It was sent point-to-point to the router (or to server by router)
3180 but it needs to be destined to a channel. The routines now
3181 supports sending the channel user mode notifys to the channels
3182 when announcing clients and channels. Affected files are
3183 silcd/server.c and silcd/packet_receive.c.
3185 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3186 It did not actually replace the old channel entry in the cache.
3187 Affected file lib/silcclient/client_notify.c.
3189 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3191 * Fixed a possible crash in silc_packet_send_prepare. It now
3192 assures always that there is enough space in the buffer and
3193 at the tail area of the buffer (for MAC).
3195 Fixed the inbound buffer reallocation in silc_packet_read.
3196 It was old code and did not handle the reallocation correctly.
3199 The affected file is lib/silccore/silcpacket.c.
3201 * Fixed buffer overflow in silc_parse_nickname in the file
3202 lib/silcutil/silcutil.c.
3204 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * make install generates new server keys only if there is not
3209 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3212 Added check that if the NOREPLY is set then we will not send
3213 the away message. This avoids infinite loop of away messages
3214 if both clients are away. The affected file is
3215 lib/silcclient/client_prvmsg.c.
3217 * Fixed client crash if /NICK was given without arguments.
3218 Affected file lib/silcclient/command.c.
3220 * Server does not send the invite list in INVITE command back
3221 to the client if the list was not altered. Added this notion
3222 to the protocol spec as well. Affected file silcd/command.c.
3224 Fixed possible crash in INVITE command by checking the
3225 value of silc_server_get_client_route command.
3227 * Fixed the INVITE notify type handling. The arguments are now
3228 taken in correct order and client does not crash. The affected
3229 file is irssi/src/silc/core/silc-channels.c.
3231 Removed the "Inviting xxx to channel" message from the
3232 client library away and let the application handle it.
3233 Affected file lib/silcclient/command.c. Added that message
3234 to Irssi SILC client's message formats.
3236 * Fixed CMODE command crash in client. It now checks the
3237 amount of arguments correctly and does not crash. The affected
3238 file is lib/silcclient/command.c.
3240 * Do not create new channel automatically in silc_channels_join
3241 but check whether the channel by that name already exists.
3242 Affected file irssi/silc/core/silc-channels.c.
3244 * Do not send the SERVER_SIGNOFF to router if the disconnected
3245 entity was the router. Affected file silcd/server.c.
3247 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3248 SILC client as it was missing from there.
3250 Added the handling of the KICK notify to the Irssi SILC client
3251 as it was missing. Added "you have been kicked" message to
3252 Irssi SILC client's message modules formats.
3254 Added the handing of the KILL notify to the Irssi SILC client
3255 as it was missing. Added the kill message module formats
3258 The affected file is irssi/src/silc/core/silc-channels.c.
3260 * The router did not save the channel mode the server announced.
3261 Affected file silcd/packet_receive.c.
3263 * Fixed a possible crash in INFO command in server. If the
3264 server did not provide the server info it crashed. Affected
3265 file silcd/command.c.
3267 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Fixed the GETKEY command in the server to check also the
3270 global list. Otherwise the GETKEY would not work correctly
3271 in normal SILC server. Affected file silcd/command.c.
3273 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Fixed GETKEY crash, it crashed if the command did not succseed.
3277 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3280 is now real and not just an macro interface to GMP.
3282 Removed the entire GMP from the source tree and imported new
3283 NSS MPI library instead. Reason for removing GMP is that it is
3284 extremely large and compiles extremely slow. The NSS MPI
3285 is only a few files and compiles in less than 10 seconds.
3286 The speed is also about the same as GMP. The MPI is imported
3287 to lib/silcmath/mpi.
3289 If the system has GMP installed we will still use the GMP.
3290 If it is not then the NSS MPI will be compiled.
3292 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Merged a long nickname (127 characters long) crash bugfix from
3295 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3297 * Merged a freed memory reference bugfix from Irssi CVS tree.
3298 Affected file irssi/src/core/commands.c.
3300 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Added the server's public key sving and verification to the
3303 server when performing the SKE. This was missing and the
3304 remote server's (or router's) public key was accepted without
3305 checking whether we have it previously or trust it at all.
3306 Affected file silcd/protocol.c.
3308 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Check in the silc_server_timeout_remote if protocol is active
3311 and make sure that the protocol's final callback is called so
3312 that all memory if freed. Affected file silcd/server.c.
3314 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * silc_server_whois_send_reply crashed the server if the nickname
3317 was 127 characters long. Affected file silcd/command.c.
3319 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Added sanity check to the silc_server_new_client. If the hostname
3322 is provided inside username then check that the provided hostname
3323 really is the same as the resolved one. If the hostname was not
3324 resolved then check it from the public key. Affected file is
3325 silcd/packet_receive.c.
3327 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3328 if the server disconnected us and the connection is not valid
3329 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3331 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3332 the library to the lib/silcutil/silcutil.[ch].
3334 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Close log file after open. Affected file
3337 lib/silcutil/silclog.c.
3339 * Check whether sock == NULL in silc_client_send_packet and return
3340 if it is. Affected file lib/silcclient/silcclient.c.
3342 * Check rec->entry == NULL in the Irssi SILC Client before
3343 sending the channel message. Affecte file is
3344 irssi/src/silc/core/silc-servers.c.
3346 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Merged a splitted window bugfix from Irssi CVS tree. The
3349 affected file is irssi/src/fe-text/textbuffer-view.c.
3351 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3352 It did not print nickname.
3354 * Improved the distributions system a bit.
3356 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3359 irssi/src/fe-text/gui-window.c.
3361 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3362 to in-active server. The affected file is
3363 irssi/src/silc/core/client_ops.c.
3365 * Resolve the client in USERS command reply if the entry does
3366 not have username resolved. The affected file is
3367 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3368 command to WHOIS command to really resolve stuff. The USERS
3369 is not used any more in any critical section so WHOIS can
3370 be used even though it might be slower than IDENTIFY.
3372 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3375 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Changed the protocol API a bit more consistent in the
3378 lib/silccore/silcprotocol.[ch].
3380 * Changed the following headers to ROBODoc format:
3382 lib/silccore/silcpayload.h
3383 lib/silccore/silcprotocol.h
3384 lib/silccore/silcsockconn.h
3386 All core library headers are now formatted.
3388 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Fixed a bug in Irssi SILC client; do not show that you are
3391 server/router operator if you really are not. Affected file is
3392 irssi/src/silc/core/client_ops.c.
3394 * Renamed silc_command_free_payload to silc_command_payload_free.
3395 Affected file lib/silccore/silccommand.h
3397 * Added silcmath.h to include the prototoypes of various routines
3398 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3401 * Changed the following headers to ROBODoc format:
3403 lib/silccore/silcchannel.h
3404 lib/silccore/silccommand.h
3405 lib/silccore/silcid.h
3406 lib/silccore/silcidcache.h
3407 lib/silccore/silcmode.h
3408 lib/silccore/silcnotify.h
3409 lib/silccore/silcpacket.h
3410 lib/silcmath/silcmath.h
3412 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Added checking to the server code not to start the server if
3415 ciphers and stuff are not configured properly. Affected files
3416 silcd/serverconfig.[h] and silcd/server.c.
3418 * Changed the layout of the header files of the public interfaces
3419 in the SILC libraries. The new layout supports ROBODoc
3420 documentation tool (and some others) so that it is easy to create
3421 a library reference manual. All the other headers and source
3422 code must still follow the CodingStyle document. Also source
3423 code must not include these ROBODoc stuffs, only the headers.
3424 Furthermore, all public interface headers must now be named
3425 by using `silc' prefix, example: silcapi.h, silccipher.h.
3426 Some files were renamed due to this. All the other headers
3427 must not be used as public interfaces. I will update the
3428 CodingStyle document later. Changed following headers, so far:
3430 lib/silcclient/silcapi.h
3431 lib/silccore/silcauth.h
3432 lib/silccore/silcprivate.h
3433 lib/silccrypt/silcdh.h
3435 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Removed silc_client_packet_send_flush from the client library
3440 as it is not needed. Affected file lib/silcclient/client.[ch].
3442 * Added printing of message of unresolved authentication method
3443 to the Irssi SILC client. Added it to the module formats.
3444 Removed the same message from the client library.
3446 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Added new distribution feature, DISTLABEL. Every distribution
3449 can define own preprocessor label that can be used in the
3450 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3451 file distributions, acconfig.h.pre and prepare.
3453 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Added Makefile.defines_int to include the actual definitions
3456 for Makefile.defines.in. Tested the new distribution system,
3457 created distributions and tested installation.
3459 * Added AWAY message printing to the Irssi SILC client. Added
3460 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3462 * Added SCONNECT command to call the SILC's CONNECT command.
3463 Cannot use CONNECT directly since Irssi uses that internally.
3464 Affected file irssi/src/silc/core/silc-servers.c.
3466 Added ACTION local command. It is same as ME command but takes
3467 the channel as mandatory argument.
3469 Rewrote some of the Irssi's help files to suite for SILC
3472 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Added Makefile.defines[.in] that should for now on be included
3475 in all Makefile.am file in the source tree. That file includes
3476 all common compilation definitions for SILC source tree.
3478 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Minor changes to the ./prepare script to change the package
3481 name according the distribution name to the configure.in.
3483 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Created new distribution system. Added file `distributions'
3486 that defines all the distributions that can be created out of
3487 the SILC source tree. The ./prepare script now reads that
3488 file to determine how to prepare the distributions. The
3489 first argument to the ./prepare is the name of the distribution
3490 and second is the version of the distribution. If given
3491 without arguments it creates the default (toolkit) distribution
3492 with the default version (defined in ./prepare).
3494 All Makefile.am files that are subject to the distributions
3495 are now named as Makefile.am.pre. These are ./Makefile.am
3496 and lib/Makefile.am. Others may be changed later.
3498 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Added invite list, ban list, some key management and connection
3501 error message printing to module formats in the Irssi SILC client.
3503 * Added new silc_client_set_away_message to set the away message
3504 that is back to the person who sent private message. The
3505 affected file lib/silcclient/silcapi.h and the
3506 lib/silcclient/client_prvmsg.c.
3508 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Fixed the private message sending in the Irssi SILC client,
3511 added local command KEY to the Irssi SILC client.
3513 Added key management and key agreement message formats to the
3514 irssi/src/fe-common/silc/module-formats.[ch].
3516 Added USERS (alias WHO) printing, server/router operator
3517 indication and LIST command printing to the module formats.
3519 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Fixed channel joining notify handling, cumode notify handling
3522 from Irssi SILC client.
3524 * Added SILC specific module-formats to the Irssi SILC client so
3525 that SILC specific message hilighting, colors etc is possible.
3526 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3528 Added channel mode, channel user mode, actions, notices,
3529 whois and whowas printing to the the module-formats.c.
3531 * Fixed a bug in channel deletion in the server. The channel
3532 is not left to the cache even if the channel founder auth mode
3533 is set when there are no users anymore on the channel. Affected
3534 file silcd/server.c.
3536 * The silc_net_localhost now resolves the entire hostname including
3537 the domain name. Affected file lib/silcutil/silcnet.c.
3539 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Changed the ask_passphrase client operation to be ascynchronous.
3542 It has now a completion callback and a context that the
3543 application must call after it has got the passphrase from
3544 the user. Affected files lib/silcclient/silcapi.h,
3545 lib/silcclient/protocol.c, lib/silcclient/command.c and
3548 Added SilcAskPassphrase callback that the application calls
3549 to deliver the passphrase to the library.
3551 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3552 The public key verification and especially a certificate
3553 verification is asynchronous procedure.
3555 Added new SILC_SKE_STATUS_PENDING status to indicate the
3556 request is pending and a callback will be called to finalize
3559 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3560 indicate that remote end did not send its public key (or
3561 certificate), even though we require it. Added check for this
3562 condition in the SKE. This was a security bug, now fixed.
3564 Defined new SilcSKEVerifyCbCompletion callback that is called
3565 when the verification process is completed.
3567 The affected files lib/silcske/silcske_status.h and
3568 lib/silcske/silcske.[ch].
3570 * Changed the verify_public_key client operation to be async
3571 as well. Defined SilcVerifyPublicKey callback that is used to
3572 indicate the success of the public key verification process.
3574 Changed the server and client to use the new async client
3577 * Changed the Irssi SILC client's internal scheduler to be called
3578 twice as many times as it used to be. As a result the client
3579 should be a bit faster now. Affected file is
3580 irssi/src/silc/core/silc-core.c.
3582 * Added support to Irssi SILC client of asynchronous public key
3583 verification and passphrase inquiry. Affected file is
3584 irssi/src/silc/core/silc-core.c.
3586 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Do not say "You have left channel %s" in client library.
3589 Moved it to the application. Affected files are
3590 lib/silcclient/command.c and silc/client_ops.c.
3592 * Fixed silc_client_get_clients. Command context was not
3593 duplicated and was freed memory in the callback. Affected
3594 file lib/silcclient/idlist.c.
3596 * Do not say "you are now talking..." on JOIN command in the
3597 client library. The appliation must handle it.
3599 * Do not say ".. changed topic to" in command reply in the
3600 client libary. The application must handle it.
3602 * Fixed TOPIC command sending in the client library.
3604 * Fixed a memory leak in silc_client_command_free in the file
3605 lib/silcclient/command.c.
3607 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Imported a modified version of Irssi client to the source tree.
3610 The Irssi will be used to create a new client called
3611 Irssi SILC. Imported to irssi/.
3613 Added silc_core_init_finish function to the Irssi. Affected
3614 file irssi/configure.in.
3616 A lot changes in the Makefile.ams around the irssi tree.
3618 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Do not rehash if the new size is same as the old size of the
3621 hash table, in the silc_hash_table_rehash*. The affected file
3622 lib/silcutil/silchashtable.c.
3624 * Replaced hash_table_del_by_context calls from the server
3625 (when channel->user_list and client->channels) to the
3626 hash_table_del as it is sufficient and faster.
3628 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Added silc_hash_table_list, silc_hash_table_get and the
3631 SilcHashTableList structure to provide an alternative way to
3632 traverse the hash table. The affected files are
3633 lib/silcutil/silchashtable.[ch].
3635 * Changed the server's idlist routines to use the hash table
3636 routines to optimize the code.
3638 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Replaced the client entry's `channel' list and channel entry's
3641 `user_list' list to hash tables for optimized lookup. Changed
3642 the code to use the hash table interface around the code.
3643 Affected file lib/silcd/idlist.[ch].
3645 * Added `auto_rehash' boolean argument to the function
3646 silc_hash_table_alloc to indicate whether the hash table should
3647 auto-rehash when it thinks is appropriate time. It will
3648 increase the hash table size if the there is twice as much
3649 entries in the table than the size of the table, and will
3650 decrease the size if there are twice as less entries than
3651 the size of the table.
3653 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3657 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * silc_idcache_purge_by_context deletes the entry now by context
3660 as it is supposed to do. Affected file lib/silccore/idcache.c.
3662 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3663 client is not anymore valid (WHOWAS givens the info) and not
3664 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3666 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Removed the `data' and `data_len' arguments from the ID Cache
3669 interfaces and added `name' argument. ID Cache does not handle
3670 anymore the binary data only a names associated with given ID.
3672 * When hashing a Client ID with silc_hash_id the entire ID is
3673 not hashed anymore, instead only the hash of the Client ID is
3674 hashed. This way we can access the Client ID from the cache
3675 with Client ID but with the hash of the ID (which is a hash of
3676 the nickname) as well without any difference in performance.
3678 Added also silc_idcache_find_by_id_one_ext to do one on one
3679 searching when we have the actual ID. Added also function
3680 silc_hash_client_id_compare. The affected files are
3681 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3683 * When hashing the name associated with a ID it is always done
3684 in lowercase. This way we can access the cache without worrying
3685 about case-sensitivity, even though, for example nicknames are
3688 * Fixed a bug in server with channel message sending. It put
3689 wrong ID type as destination ID. The affected file
3690 silcd/packet_send.c.
3692 * silc_idcache_del_by_context now deletes from all hash tables
3693 by context. Affected file lib/silccore/idcache.c.
3695 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Changed the client library to use the new ID Cache interface.
3698 Changes around the source tree.
3700 * Added silc_hash_table_rehash_ext to rehash with specific
3701 hash function. Affected file lib/silcutil/silchashtable.[ch].
3703 * Added silc_hash_string_compare to compare two strings in the
3704 hash table. Affected file lib/silcutil/silcutil.[ch].
3706 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added new function silc_idcache_del_by_context into the
3709 lib/silccore/idcache.[ch].
3711 * Changed the server's ID list routines to use the new ID Cache
3712 interface. Changes around the source tree.
3714 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Added silc_hash_table_del[_by_context]_ext functions in to the
3717 lib/silcutil/silchashtable.[ch].
3719 Removed silc_hash_table_find_all* routines and added new
3720 silc_hash_table_find_foreach to replace them.
3722 Added silc_hash_table_replace_ext function as extended
3723 replacing function. Separated the simple hash table interface
3724 from the extended hash table interface in the file
3725 lib/silcutil/silchashtable.h.
3727 * Fixed minor bugs and changed it to use some of the new
3728 hash table functions in lib/silccore/idcache.c
3730 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Added new function silc_hash_table_find_all to return all keys
3733 in the hash table by the specified key. As the hash table is
3734 collision resistant it also makes it possible to have several
3735 duplicate keys in the hash table. This function may be used to
3736 find all of the keys from the hash.
3738 Added user_context arguments to the SilcHashFunction,
3739 SilcHashCompare and SilcHashDestructor to deliver user specified
3742 Added new fuctions silc_hash_table_find[_all]_ext to do
3743 extended lookup with specified hash and compare functions and
3744 specified user contexts.
3746 Added new function silc_hash_table_add_ext to add the key
3747 with specified hash function and user context.
3749 Added new function silc_hash_table_foreach to traverse all
3750 entrys in the hash table. Added SilcHashForeach callback
3753 Added new function silc_hash_table_del_by_context to delete
3754 the entry only if the context associated with the key matches.
3756 Affected files are lib/silcutil/silchashtable.[ch].
3758 * Removed silc_hash_[server/client/channel]_id and added just
3759 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3760 silc_hash_id_compare to compare two ID's using as the hash table
3761 comparison function. Added also silc_hash_data to hash
3762 binary data and silc_hash_data_compare to compare it.
3764 * Removed silc_idlist_find_client_by_hash as it is not needed
3765 anymore. Affected file silcd/idlist.[ch].
3767 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3768 to use internally the SilcHashTable. The new ID Cache is a lot
3769 faster than the old one. Some of the ID Cache interface was also
3770 rewritten and obsolete and stupid functions were removed.
3772 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Added entry_count field to the SilcHashTable to keep the number
3775 of the entries in the table. Implemented the function
3776 silc_hash_table_rehash. Added new function
3777 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3779 Fixed a minor bug in silc_hash_table_free.
3781 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3782 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3783 into the lib/silcutil/silcutil.[ch].
3785 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Implemented a collision resistant hash table into the
3788 lib/silcutil/silchashtable[ch]. See the header and the source
3789 for the SilcHashTable API.
3791 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Merged dotconf version 1.0.2 into lib/dotconf.
3795 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Do not compile anything in lib/silcsim/* if the SIM support
3798 is not enabled. The tree should now compile without problems
3801 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Compiled the SILC under cygwin. Compiled and tested briefly
3804 without problems. More tests needed. The SIMs didn't compile
3807 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3809 * Fixed possible crash in silc_get_username in the
3810 lib/silcutil/silcutil.c.
3812 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Fixed a va_arg in silc/client_ops.c.
3816 * Oops, RC5 routines were named AES and caused some problems
3817 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3819 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added new SilcIDIP structure into the lib/silccore/id.h and
3822 replaced the old `ip' fields from all SILC ID's to that type.
3823 This is a step towards IPv6 support.
3825 The silc_id_get_len takes now the ID as an extra argument.
3826 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3827 both IPv4 and IPv6 based ID's.
3829 The affected files are lib/silccore/id.[ch] and other files
3830 around the tree using these routines.
3832 * Removed the ID length arguments in server from various
3833 silc_server_send_notify_* routines -> they are not needed
3836 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * Fixed memory leak in silc_encode_pem_file in the file
3839 lib/silcutil/silcutil.c.
3841 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Check minor version as well in the SKE. Affected files are
3844 silcd/protocol.c and lib/silcclient/protocol.c.
3846 * Added --identifier option to the server so that an identifier
3847 can be when creating the public key for the server. Affected
3848 file is silcd/silcd.c.
3850 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3851 lib/silccrypt/silcpkcs.c.
3853 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Register default ciphers and stuff when using -C option with
3856 the server. Affected file sildc/silcd.c.
3858 * Put back the servers public key filename format, it is better
3859 than the new one. For now, the client keys are saved with the
3860 new filename format. The affected file silc/client_ops.c.
3862 * Implemented the Cipher API for the rest of the ciphers that
3863 did not implement it or implemented it the wrong way.
3865 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Register default ciphers and stuff when using the -S option
3868 in the client. Affected file silc/silc.c. Same also when
3869 creating new key pair with -C option.
3871 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Fixed the silc_verify_public_key client operation function to
3874 save the public keys differently. The fingerprint is now
3875 used as filename and not the hostname. This way also the
3876 client keys are saved uniquely and not with hostnames. The
3877 affected file is silc/client_ops.c.
3879 * Trimmed the silc_hash_fingerprint function to remove extra
3880 whitespaces from the end of the fingerprint. The affected
3881 file is lib/silccrypt/silchash.c.
3885 * Added silc_cipher_register_default function to register all
3886 default ciphers. It can be used when configuration files
3887 does not exist and the application does not want any specific
3888 ciphers in any specific order.
3890 The SilcDList is now used as silc_cipher_list dynamically
3891 allocated cipher list. Removed the static list all together
3892 and now all ciphers must be allocated to the dynamic list.
3893 The silc_cipher_alloc routine was changed to check only the
3896 All silc_cipher_* routines that used to return int returns
3899 The affected files lib/silccrypt/silccrypt.[ch].
3901 * The same thing was done to silc_hash_* as for silc_cipher_*
3902 routines. Affected files lib/silccrypt/silchash.[ch].
3904 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3905 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3906 Added also silc_pkcs_[un]register[_default] functions.
3907 Removed the data_context from the PKCS API.
3909 * Added silc_hmac_register_default function to register default
3910 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3911 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3912 to unregister all hmacs at once.
3914 * Register the default ciphers, hash functions, PKCSs and HMACs
3915 if client's configuration file does not exist. The affected
3918 * The client did not load the hash functions from the SIM
3919 modules at all. Added support for this. Affected file is
3920 silc/clientconfig.c.
3922 * When decoding public key with silc_pkcs_public_key_decode, check
3923 the supported algorithm only if PKCS are registered. Affected
3924 file lib/silccrypt/silcpkcs.c. The same was done with the
3925 silc_pkcs_private_key_decode.
3927 * Fixed the SILC List routines to keep the list always in order.
3928 It used to change the list's order when traversing the list but
3929 not it preserves the order. Affected file lib/trq/silclist.h.
3931 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Added the client library to use the SilcSocketConnection's
3934 reference counter (by silc_socket_dup) to prevent the bug that
3935 the socket object may be freed underneath async operation.
3937 * The name resolv library checking fixes in the configure.in.pre.
3940 * Created new version of the protocol drafts for future
3941 development. The -03 drafts are the ones that will be changed
3942 in the trunk now and the -02 will remain as they are.
3944 * Send list of CUMODE notifys to the router when announcing
3945 the channel users to the router. Affected file silcd/server.c.
3946 If the router receiving channel founder CUMODE for a channel
3947 that already has channel founder it will send CUMODE notify
3948 to the sender to remove the channel founder rights from the
3949 announced client. Affected file silcd/packet_receive.c.
3951 * The CUMODE notify may now use Server ID as well as the entity
3952 who changes the mode. Updated protocool specs.
3954 * Updated INSTALL and README files.
3956 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * New web pages in the http://silc.pspt.fi. The pages was
3963 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Implemented the [DenyConnectin] config section in the server.
3966 Added silc_server_config_denied_conn to check whether incoming
3967 connection is denied. Affected file silcd/serverconfig.[ch].
3969 * Do not check the ports when checking the incoming configuration
3970 data if the port is 0, meaning any. Affected file is
3971 silcd/serverconfig.c.
3973 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Fixed buffer overflow in silc_string_compare in the file
3976 lib/silcutil/silcutil.c.
3978 * Fixed double free in silc_server_command_leave in the file
3981 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Fixed the version checking in the server. Affected file is
3986 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Fixed the configuration data fetching when accepting new
3989 connections in the server. Affected file silcd/server.c.
3991 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Added `sender_entry' argument to the function
3994 silc_server_packet_relay_to_channel so that we can check
3995 whether some destination actually belongs to the same route
3996 the sender belongs (ie, we must not resend the packet to the
3997 sender). Affected file silcd/packet_send.[ch].
3999 * Added `servername' field to the SilcClientEntry in the server
4000 to hold the name of the server where client is from. Affected
4001 file is silcd/idlist.h.
4003 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Moved the channel message encrypting in the router betwen
4006 router connections from silc_server_channel_message to the
4007 silc_server_packet_relay_to_channel since we want to check
4008 whether we have anybody channel before encrypting anything.
4009 Affected files silcd/packet_[receive/send].c.
4011 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Fixed the [AdminConnection] server config section to support
4014 multiple entries. Affected file silcd/serverconfig.c.
4016 * Added support into the server to check the validity of the
4017 incoming connection before executing any KE or authentication
4020 * The connection configuration is now saved to the KE and
4021 connection auth protocol contexts and not fetched anymore in
4022 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4024 * The local hosts listenning address and port is also resolved
4025 now when starting the server. We want to have the socket object
4026 to include the real address and port for the listener. Added
4027 new function silc_net_check_local_by_sock into the files
4028 lib/silcutil/silcnet.[ch].
4030 * Fixed a broadcast bug in server -> do not broadcast if we
4033 * Fixed a routing bug. Do not route broadcast packets ever.
4034 Broadcast packets must be processed always and not routed since
4035 they may be destined to some other host than yourself and thus
4036 would get routed without no good reason. Affected file is
4039 * Added function silc_server_config_is_primary_route to check
4040 whether primary router connection has been configured (a router
4041 configuration that we are initiating). If there is not, we
4042 will assume that there is only two routers in the SILC network
4043 and we will use the incoming router connection as our primary
4044 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4046 * Changed the order of the broadcasting. Broadcast _after_ the
4047 packet has been processed not before. Affected file is
4050 * Fixed a [ClientConnection] parsing bug. The port was never
4051 parsed correctly thus resulting to port 0. Affected file
4052 silcd/serverconfig.c.
4054 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4055 argument and did not set the broadcast packet flag. Affected
4056 file silcd/packet_send.c. Fixed same bug in the function
4057 silc_server_send_notify as well.
4059 * If we receive NEW_ID packet for our own ID in the server, ignore
4062 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Removed the nickname from the Private Message Payload.
4067 Updated the code and the protocol specs.
4069 * Updated protocol specs for submitting to the IETF.
4071 * Tweaked the Random Number Generator a bit. Affected file
4072 lib/silccrypt/silcrng.c. Exported a new function
4073 silc_rng_[global]_add_noise which can be used to add more
4076 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Do not parse packets with different timeout when protocol
4079 is active -> may cause problem with rekey. Affected file
4082 * When server receives signoff notify it must not create
4083 new channel key if the client is on any channels since the
4084 sender of the signoff notify will create it.
4086 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Added printing of error messages during SKE protocol from the
4089 failure packet sent by server during SKE. Affected file
4092 * Removed the client's failure_callback handling with timeout
4093 and handle it immediately when received.
4095 * The SKE library returned wrong type in SUCCESS and FAILURE
4096 packets. They must be 32 bit MSB not 16 bit MSB.
4098 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Ok, rewrote the logic of the re-key and now it seems to work.
4101 I tested it on high traffic with frequent re-keys without
4102 problems. Added hmac_receive (and renamed hmac to hmac_send)
4103 in SilcClientConnection in lib/silcclient/client.h and
4104 in SilcIDListData in silcd/idlist.h. Also, removed the
4105 SilcPacketParserContext's cipher and hmac fields as they are
4106 not needed anymore and actually caused some problems when
4107 the ciphers and hmac's changed underneath the packet parser.
4109 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * If re-key protocol is active then process the incoming packets
4112 synchronously since we must assure that icoming packets encrypted
4113 with the old key is processed before the new keys is set to
4114 use. This is true other packets than for REKEY packets.
4115 Affected file silcd/server.c. The same was done to client library
4116 as well, affected file lib/silcclient/client.c.
4118 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Fixed bug in client and server to accept the force send if
4121 the packet is send from silc_[server/client]_packet_process
4122 function. Otherwise the packets are never delivered, oops.
4124 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Disable force sending of packets when REKEY protocol is active.
4127 We must assure that no packet is sent directly when rekey is
4128 performed. All packets must be sent through packet queue.
4129 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4130 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4131 function is silc_[server/client]_packet_send_real to check
4134 * Replaced the SIM paths from example config files to
4135 /usr/local/modules. Also, make install creates now
4136 /usr/local/silc/logs directory to hold all the SILC server
4139 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Made the configure.in.pre work on Solaris. Patch by salo.
4143 * Made all ciphers compatible with non-x86 machines. Defined
4144 CBC mode macros into lib/silccrypt/ciphers_def.h.
4146 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Fixed the make install.
4150 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * When MAC computation fails the silc_packet_decrypt returned 0
4153 even though it was supposed to return -1. Fixed this. The
4154 affected file is lib/silccore/silcpacket.c.
4156 * Do not replace the config files in /etc/silc (in make install)
4157 if they already exist. Affected file ./Makefile.am.
4159 * Do not send re-key packets immediately but through packet queue.
4160 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4162 * Changed silc_net_check_host_by_sock to return FALSE if the
4163 IP/DNS could not be resolved. Though, it returns the IP address
4164 now even if it could not resolve it (but returns also FALSE).
4165 Affected file lib/silcutil/silcnet.[ch].
4167 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Added silc_pkcs_decode_identifier to decode the public key's
4170 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4171 Added also silc_pkcs_free_identifier. Added also new context
4172 SilcPublicKeyIdentifier.
4174 * Added -S option to the silc client. It is used to dump the
4175 contents of the specified public key file.
4177 * Changed the PKCS api to return the public key length when
4178 setting the public key.
4180 * Fixed a fatal bug in the public and private key file loading.
4181 Affected file lib/silccrypt/silcpkcs.c.
4183 * Execute the packet parsing for client with zero (0) timeout
4184 if the protocol is active. Affected file silcd/server.c.
4186 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Made the key generation options to the silcd program. Added
4189 -C option, equivalent to client's option.
4191 * Added new [ServerKeys] config section to the server. It
4192 configures the server's public and private key.
4194 * Defined generic Public Key Payload into the protocol
4195 specification to send specific type of public keys and
4198 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4199 public key or certificate.
4201 * Implemented the GETKEY command to the server and to the
4202 client library and on user interface.
4204 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Made preliminary `make install' work.
4208 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Added SilcServerRekey context into silcd/idlist.h.
4212 * Added the PFS support as defined in the specification to the
4213 SKE protocol. Affected files lib/silcske/*.c.
4215 * Added `ske_group' field to the SilcServerRekey context to hold
4216 the number of the SKE group that is used with PFS in re-key.
4217 Affected file silcd/idlist.h.
4219 * Added PFS re-key support to the server. Affected file is
4222 * Added silc_protocol_cancel to cancel execution of the next
4223 state of the protocol. Affected file is
4224 lib/silccore/silcprotocol.[ch].
4226 * Added the re-key support with and without PFS to the client
4227 library. Re-key is performed once in an hour, by default.
4229 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4230 Added silc_client_rekey_callback and silc_client_rekey_final.
4231 Affected files are lib/silcclient/protocol.[ch] and
4232 lib/silcclient/client.[ch].
4234 * Removed the `hmac_key' and `hmac_key_len' fields from the
4235 SilcClientConnection structure; not needed. Affected file is
4236 lib/silcclient/client.h.
4240 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Do not ask whether user wants to use the negotiated private key
4243 for private messages, just use it. Affected file is
4244 silc/local_command.c.
4246 * Added `send_enc_key' and `enc_key_len' fields to the
4247 SilcIDListData structure since they are needed in the re-key
4248 phase. Affected file is silcd/idlist.[ch].
4250 * Implemented the simple re-key protocol into the server.
4251 Affected files silcd/server.c and silcd/protocol.[ch]. The
4252 re-key will be performed once in an hour, by default.
4254 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4255 Added silc_server_rekey, silc_server_rekey_callback and
4256 silc_server_rekey_final.
4258 * Removed Tunneled flag from the protocol. Updated the code
4259 and the specifications.
4261 * Adde `pfs' field to the SilcIDListData to indicate whether
4262 the PFS is to be performed in the re-key. Affected file is
4265 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4268 int64 of at least the xintXX size. If void * is less that 4
4269 bytes uint32 * will be used. Defined bool as boolean.
4271 * Changed _ALL_ unsigned long and unsigned int to uint32,
4272 unsgined short to uint16 in the source tree.
4274 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4275 not handle clients that has entry->data.registered == FALSE.
4276 They are not in the network anymore. Affected file is
4279 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4281 * Implemented the sending of the SERVER_SIGNOFF notify in the
4282 server. Affected file is silcd/server.c.
4284 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4285 Added also silc_notify_payload_encode_args into the
4286 lib/silccore/silcnotify.[ch].
4288 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4289 Affected file silcd/packet_receive.c.
4291 * Implemented the SERVER_SIGNOFF notify handling in the client
4292 library. Affected file lib/silcclient/client_notify.c. Also,
4293 implemnted the printing of the SERVER_SIGNOFF info to the
4294 application. Affected file silc/client_ops.c.
4296 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4297 if the deleting was successful. Affected file silcd/idlist.[ch].
4299 * Added support for public key authentication in the connection
4300 authentication protocol in the client library. Affected file
4301 lib/silcclient/protocol.c.
4303 * Changed the server's silc_idlist_get_clients_by_* interface
4304 to support already allocated array so that new entries may be
4305 added to pre-allocated array. Affected file silcd/idlist.[ch].
4306 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4307 and command replies.
4309 * All command reply functions in the server now calls the
4310 pending command callback even if error occured. This way the
4311 error will be delivered to the client as well. Affected files
4312 silcd/command.c and silcd/command_reply.c.
4314 * Fixed INFO command to return local server's info if no server
4315 was provided. Affected file lib/silcclient/command.c.
4317 * Removed RESTART command for good. Updated the code and the
4320 * Rewrote parts of the task system. It is a bit simpler now.
4321 Removed unsued task priorities. The affected files are
4322 lib/silcutil/silctask.[ch].
4324 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Moved the USERS printing from the library to the application.
4327 Affected files lib/silcclient/command.c and silc/client_ops.c.
4329 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added channel key re-key support. The re-key is perfomed
4334 only by the router and is done once in an hour. Added `rekey'
4335 field to the SilcChannelEntry in the server. Affected files
4336 silcd/server.c and silcd/idlist.h.
4338 * Added silc_task_unregister_by_context into the file
4339 lib/silcutil/silctask.[ch].
4341 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Added SILC_UMODE_GONE mode to indicate when the client is not
4344 present in the SILC network. Added also support to the local
4345 command AWAY that will set this mode. Added support of showing
4346 "xxx is gone" in WHOIS command. The USERS command shows the
4347 gone status as well.
4349 * Fixed setting server and router operator privileges in the
4350 server's UMODE command. Affected file silcd/command.c.
4352 * Merged the SKE KE1 and KE2 payloads into one payload. The
4353 new KE payload is equivalent to the old KE2 payload.
4355 Cleaned up the SKE Start Payload parsing. It now uses the
4356 simple buffer unformatting to do the parsing. A lot faster
4359 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4360 to the SKE that is used to indicate whether both of the SKE
4361 parties should perform authentication. By default only the
4362 responder performs authentication. By setting this flag also
4363 the initiator must do authentication. By default it is unset
4364 since in normal SKE case, client to server connection, only
4365 the responder should do authentication. When doing SKE between
4366 two clients both should perform authentication. Updated the
4367 code and the protocol specs.
4369 * A little fix to IDENTIFY command in the server. Search the
4370 client first by hash not nickname. Affected file is
4373 * Fixed the silc_client_close_connection to support closing
4374 the client to client connections wihtout deleting too much
4375 data. Affected file lib/silcclient/client.c.
4377 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4378 are received if protocol used to be active but is not anymore
4379 the application would crash due to NULL pointer dereference.
4380 Affected files silcd/server.c and lib/silcclient/client.c.
4382 * Added `hash' field to the SilcClientConnection to include
4383 the hash function negotiated in the SKE protocol.
4385 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4386 to set the channel founder authentication data. A client can
4387 claim the founder rights later by providing the authentication
4388 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4389 This way the channel founder can regain the channel founder
4390 privileges even it is left the channel. This works only on
4391 local server and the client must be connected to the same
4392 server to be able to regain the founder rights. Updated the
4393 protocol specs accordingly.
4395 Added support to the CMODE command in the client to set the
4396 founder auth data. Read the README to see how to set it.
4398 Added support to the CUMODE command to claim the founder
4399 rights. Read the README to see how to do it.
4401 Added support for the founder authentication to the Channel
4402 Entry in the server. Affected file silcd/idlist.h.
4404 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4405 server's CMODE command. Affected file silcd/command.c.
4407 * Added the following new functions into lib/silccore/silcauth.[ch]:
4408 silc_auth_get_method and silc_auth_get_data.
4410 * The server now saves the remote hosts public key to the
4411 SilcIDListData pointer. Affected file silcd/protocol.c.
4413 * The normal server now does not remove the channel entry from
4414 the cache if the founder authentication data is set. It used
4415 to remove it if the founder was the last one on the channel on
4416 the server and left the channel. The auth data is saved and
4417 if the channel is re-joined later the old entry is used with
4418 the old auth data. Affected files silcd/command_reply.c and
4421 * Removed the `pkcs' field from the SilcIDListData structure
4422 in the server; it is not used. Affected file silcd/idlist.h.
4424 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Fixed packet processing on slow links. Partial packets were
4427 never re-processed because the incoming data buffer was cleared
4428 by the application. Application must not directly clear the
4429 sock->inbuf, the packet processing routines handle it. Fixed
4430 this in client library and in server.
4432 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Fixed the WHOIS and IDENTIFY send reply function to really
4435 check whether to send list or just one entry. Affected file
4438 * Cleaned up the LEAVE command's channel key distribution. The
4439 affected file silcd/command.c.
4441 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4442 can enforce the channel mode as well. In that case the ID
4443 includes the ID of the server. The code now enforces the
4444 mode change if the router have different mode than the server.
4446 * The notify client operation with CMODE_CHANGE notify can now
4447 return NULL client_entry pointer if the CMODE was not changed
4448 by client. Application must check for this.
4450 * Added <Server ID> argument to INFO command to support server
4451 info fetching by Server ID.
4453 * Added silc_server_announce_get_channel_users to get assembled
4454 packets of channel users of the specified channel. Affected
4455 file silcd/server.[ch].
4457 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4458 was freed underneath the ID Cache.
4460 * Re-announce clients when the server received CHANNEL_CHANGE
4461 notify from the router. Affected file silcd/packet_send.c.
4463 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4466 crashed since it did not handle the fact that there is no cipher
4467 called "3" and didn't check the error condition. Now fixed.
4469 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4470 flag. It can be used to send message requests.
4472 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Implemented the RESTART command in the client.
4476 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4477 notice type messages. Added notice printing to the user
4480 * The channel keys are not re-generated if the channel's mode
4481 is PRIVKEY, ie private key on the channel exists. Affected
4482 files silcd/server.c and silcd/command.c.
4484 * Fixed a little bug in channel message delivery when channel
4485 private keys are set in the server. Affected file is
4486 silcd/packet_send.c.
4488 * Changed the setting on channel->on_channel = TRUE from the
4489 silc_client_save_channel_key to the JOIN command reply. The
4490 key payload is not received if the private channel key is set.
4491 Affected file lib/silcclient/command_reply.c and the
4492 lib/silcclient/client_channel.c.
4494 * When the CMODE_CHANGE notify is sent and the channel private
4495 key mode is removed the channel key must be re-generated in
4496 other cells as well. Added this support for the router in the
4497 silcd/packet_receive.c.
4499 * Added new local command NOTICE to send notice message on
4500 channel. Affected file silc/local_command.[ch].
4502 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added new local command ME to the client. It is used to send
4505 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4506 some action. Affected file silc/local_command.[ch].
4508 * Changed channel_message and private_message client operations
4509 to deliver the message flags to the application. Added also
4510 the `flags' arguments to the silc_client_send_channel_message
4511 and silc_client_send_private_message functions. Affected file
4514 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Redefined the Private Message Payload to support private message
4517 keys and to support the new private message flags. Updated
4518 the protocol specs. Flags makes it possible to have for example
4519 CTCP style messages.
4521 * Added new type SilcPrivateMessagePayload and defined an API
4522 for it in the lib/silcclient/silcprivate.[ch].
4524 * Tested private message private keys successfully. Tested the
4525 private message key set, unset and list commands with the new
4528 * Redefined the Channel Message Payload to include the channel
4529 message flags (equal with private message flags) to support
4530 for example CTCP style messages.
4532 * Defined some of the message (for channel and private message)
4533 flags. Updated the protocol specs and added the flags to the
4534 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4536 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Added SilcKeyAgreementStatus type to the key agreement routines
4539 to indicate the current status and error if one occured.
4540 The status types are defined in the lib/silcclient/silcapi.h.
4542 * Added new local command KEY that is used to set and unset private
4543 keys for channels, set and unset private keys for private messages
4544 with remote clients and to send key agreement requests and
4545 negotiate the key agreement protocol with remote client. The
4546 key agreement is supported only to negotiate private message keys,
4547 it currently cannot be used to negotiate private keys for channels,
4548 as it is not convenient for that purpose.
4550 * Fixed a minor pending callback setting bug in the function
4551 silc_client_get_client_by_id_resolve, now the function works.
4552 Affected file lib/silcclient/idlist.c.
4554 * Added function silc_net_get_local_port to get local bound
4555 port by socket. Added to lib/silcutil/silcnet.[ch].
4557 * Added `sockets' and `sockets_count' fields to the SilcClient
4558 object. They hold the sockets of the listenning sockets in
4559 the client. Listenning sockets may be for example the key
4560 agreement server. Affected file lib/silcclient/client.[ch].
4561 Added functions the silc_client_add_socket and the
4562 silc_client_del_socket. They are exported to the application
4565 * Added ~./silc/clientkeys to support other client's public keys.
4567 * Renamed verify_server_key client operation to verify_public_key
4568 and added one argument to indicate the type of the connection
4569 (server, client etc.).
4571 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Added silc_server_connection_auth_request to handle the
4574 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4575 silcd/packet_receive.[ch].
4577 * Added silc_server_send_connection_auth_request into the
4578 silcd/packet_send.c to send the connection auth request packet.
4580 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4583 * Fixed the public key authentication in responder side in the
4584 server. The `auth_data' pointer includes the SilcPublicKey
4585 not the path to the public key. Affected file silcd/protocol.c.
4587 * Implemented the public key authentication in the initiator side
4588 in the server. Affected file silcd/protocol.c.
4590 * Removed the [RedirectClient] config section from the server
4591 configuration. Is not needed and I don't want to implement it.
4593 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Cleaned up the CMODE command in the server. It now works
4596 correctly and supports all the modes defined in the protocol.
4597 Affected file is silcd/command.c.
4599 * Added `hmac_name' field to the SilcChannelEntry in the server
4600 to hold the default HMAC of the channel. It can be set when
4601 creating the channel (with JOIN command). Affected files
4604 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4605 type to indicate the change of the current cipher and hmac
4606 on the channel. Client can safely ignore the <cipher> argument
4607 (if it chooses to do so) since the CHANNEL_KEY packet will
4608 force the channel key change anyway. The <hmac> argument is
4609 important since the client is responsible of setting the new
4610 HMAC and the hmac key into use.
4612 * Fixed the CMODE command in the client library as well.
4614 * Tested CMODE command in router environment successfully.
4616 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Show the version of the remote client (or server) when connecting
4619 to the server. It is logged to the log file. Affected file
4620 is silcd/protocol.c.
4622 * Fixed the KILLED notify handling in the client library. The
4623 client must be removed from all channels when receiving the
4626 Also, do not remove the client entry when giving the KILL
4627 command but when the KILLED notify is received.
4629 * Removed silc_idlist_find_client_by_nickname from the server.
4630 Not needed anymore. Affected files silcd/idlist.[ch].
4632 * Implemented the CHANNEL_CHANGE notify type handling to the
4633 server. Affected file silcd/server.c.
4637 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Added silc_server_send_notify_invite to send the INVITE
4640 notify between routers.
4642 * Implemented the INVITE command correctly to the server.
4644 * Implemented the INVITE notify type handling in the server.
4646 * Implemented the INVITE command to the client library and on the
4649 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Added function silc_server_get_client_resolve to find the
4652 client entry by ID from all ID lists and then resolve it
4653 (using WHOIS) if it cannot be found. Affected file is
4656 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Implemented the BAN command to the client library.
4660 * The JOIN command in the server now checks the invite list
4663 * Changed the silc_command_reply_payload_encode_va and the
4664 silc_command_payload_encode_va to support that if argument is
4665 NULL it ignores and checks the next argument. Affected file
4666 lib/silccore/silccommand.c.
4668 * Added silc_server_send_notify_ban to send the BAN notify
4669 type between routers.
4671 * Chaned the silc_notify_payload_encode to support that if
4672 argument is NULL it ignores and checks the next argument.
4673 Affected file lib/silccore/silcnotify.c.
4675 * Tested ban lists in router environment successfully.
4677 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Implemented BAN command to the server, in silcd/command.[ch].
4681 * Removed the BAN and INVITE_LIST modes from the CMODE command
4684 * Added function silc_string_match to regex match two strings.
4685 Affected files lib/silcutil/silcutil.[ch].
4687 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Redefined parts of the SilcChannelEntry in the server to support
4690 the new ban and invite lists.
4692 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Redefined the INVITE command. The same command can be used to
4695 invite individuals to the channel but also to manage the invite
4696 list of the channel (to add to and remove from the invite list).
4697 Updated the protocol specs.
4699 * Added new command SILC_COMMAND_BAN that can be used to manage
4700 the ban list of the channel. Updated the protocol specs.
4702 * Removed the channel modes: the SILC_CMODE_BAN and the
4703 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4704 in the CMODE command. The equivalent features are now available
4705 using INVITE and BAN commands. Updated the protocol specs.
4707 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4708 in the network about change in the current ban list. The notify
4709 type is not used by the client.
4711 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4712 support the invite lists.
4714 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Added new function silc_string_regexify that converts string
4717 including wildcard characters into regex string that can
4718 be used by the GNU regex library. Added into the file
4719 lib/silcutil/silcutil.[ch].
4721 Added silc_string_regex_combine to combine to regex strings
4722 into one so that they can be used as one regex string by
4723 the GNU regex library. Added into the file
4724 lib/silcutil/silcutil.[ch].
4726 Added silc_string_regex_match to match two strings. It returns
4727 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4729 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Imported GNU regex to the soruce tree into lib/contrib.
4732 Fixed some compiler warning from the regex.c.
4734 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Fixed MOTD command in the server to work in router environment.
4738 * Fixed the MOTD command in the client library to support
4739 the server argument in the command.
4741 * Added `nickname_len' argument to the silc_idlist_add_client
4742 in the server, as the `nickname' argument may be binary data
4745 * Added silc_idlist_get_channels to return all channels from
4748 * Implemented LIST command to the server. Affected file is
4751 * Implemented the LIST command to the client library and on the
4754 * Added [<user count>] argument to the LIST command reply.
4755 With private channels the user count is not shown.
4757 * Updated TODO and README.
4759 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * The client entry's data.registered must be TRUE even with
4762 global client entry on global client list. The data.registered
4763 is used to check whether the client is anymore in the network,
4764 for example with WHOWAS command so it must be valid.
4766 * Fixed the WHOWAS command in the server. It now actually works
4767 in router environment. Added function into silcd/command_reply.c
4768 silc_server_command_reply_whowas_save.
4770 * Added silc_idlist_purge function to the silcd/idlist.c
4771 to periodically purge the ID Cache.
4773 * Fixed INFO command in the server. It works now in router
4774 environment. Added <server name> argument to the INFO command
4775 reply. Updated the protocol specs.
4777 * Fixed minor bug in silc_idcache_purge to not purge if the
4778 expire value is zero.
4780 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4781 they were buggy because of the WHOWAS information.
4783 * Fixed local command MSG to handle the async resolving of
4784 the remote client properly. It used to fail the first MSG.
4785 Affected file silc/local_command.c.
4787 * Added `data_len' field to SilcIDCache context.
4789 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Update TODO. Todo in commands in the server.
4793 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4796 used by routers as broadcast packet to inform other routers
4797 about the changed user mode.
4799 Implemented the notify handling in the server. Affected file is
4800 silcd/packet_receive.c. Added the function
4801 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4803 * Added new generic Channel Payload and deprecated the New Channel
4804 Payload. The New Channel Payload is now the generic Channel
4807 * Added new argument `mode' to the silc_server_send_new_channel
4808 as it is required in the Channel Payload now.
4810 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4811 and created a new and real SilChannelPayload to represent the
4812 new generic Channel Payload. Implemented the encode/decode
4813 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4815 * Added silc_server_get_client_channel_list to return the list
4816 of channels the client has joined for WHOIS command reply.
4817 Affected file silcd/server.[ch].
4819 * Implemented the channel list sending in the WHOIS command reply
4820 in server and in the client.
4822 Implemented the channel list displaying on the user interface
4823 as well. Affected file silc/client_ops.c.
4825 * Added silc_channel_payload_parse_list to parse list of Channel
4826 Payloads. It returns SilcDList list of SilcChannelPayloads.
4827 Client for example can use this function to parse the list of
4828 channels it receives in the WHOIS command reply. The caller
4829 must free the list by calling silc_channel_payload_list_free.
4830 Affected files lib/silccore/silcchannel.[ch].
4832 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Added one new argument <user mode> to the WHOIS command reply
4835 to return the mode of the user in SILC. Updated the protocol
4838 Implemented it to the server and client.
4840 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Fixed the mode printing on the user interface on joining.
4843 Affected file silc/client_ops.c.
4845 * Implemented the UMODE command and user modes in general to the
4846 client library and to the user interface.
4848 * Implemented the UMODE command to the server.
4850 * The server now sends UNKNOWN_COMMAND error status if client sends
4851 unknown command. Affected file silcd/command.c.
4853 * All server commands now handle the command identifier the right
4854 way when sending the command reply to the client. The client can
4855 use to identify the command replies with the identifier.
4857 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Added silc_server_get_client_route to resolve the route to
4860 the client indicated by the client ID. Affected file is
4863 * Added silc_server_relay_packet as general function to relay
4864 packet to arbitrary destination. This deprecates functions
4865 like _send_private_message_key, _relay_notify etc. Affected
4866 file is silcd/packet_send.[ch].
4868 Removed silc_server_send_key_agreement,
4869 silc_server_send_private_message_key and
4870 silc_server_packet_relay_notify functions from the file
4871 silcd/packet_send.[ch].
4875 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4876 server. Affected file silcd/packet_receive.[ch].
4878 * Implemented the KILL command to the client. Implemented the
4879 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4880 Affected files lib/silcclient/command[_reply].c and
4881 lib/silcclient/client_notify.c. Implemented the KILL notify
4882 printing in the user inteface.
4884 * Fixed a lot silc_parse_nick memory leaks from the client
4885 library in the file lib/silcclient/command.c.
4887 * Changed the silc_server_send_notify_on_channels's `sender'
4888 argument from SilcSocketConnection to SilcClientEntry to
4889 check the sender as entry and not as connection object and not
4890 to send to the client provided as argument. The affected file
4891 is silcd/packet_send.[ch].
4893 * The notify packets that are destined directly to the client used
4894 to not to be processed by the server. Now changed that and the
4895 server processes all notify packets. After relaying the packet
4896 to the client the notify packet is processed in the server.
4898 * The silc_server_free_client_data now checks whether there is
4899 pending outgoing traffic for the client and purges the data to
4900 the network before removing the client entry.
4902 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4905 an client is killed from the SILC Network. Updated the protocol
4908 Added new function silc_server_send_notify_killed to the
4909 silcd/packet_send.[ch].
4911 * Added function silc_server_packet_relay_notify to relay notify
4912 packets that are destined directly to a client. In this case
4913 the server does not process the notify packets but merely relays
4914 it to the client. Affected file silcd/packet_send.[ch].
4916 Added also silc_server_packet_process_relay_notify to check
4917 whereto relay the notify. Affected file is
4918 silcd/packet_receive.[ch].
4920 * Implemented the KILL command to the server.
4924 * Added the backup schema desgined last fall to the protocol
4925 specs for everyone to see. The specification is in the
4926 *-spec-xx.txt draft and the packet type definitions for the
4927 backup routers is in *-pp-xx.txt draft. Thusly, added also
4928 new packet type SILC_PACKET_CELL_ROUTERS.
4930 * A big security problem in the implementation discovered. The
4931 signoff of an client did not cause new channel key generation
4932 which it of course should've done. The channel keys must be
4933 always re-generated when client leaves (or signoffs) the channel.
4934 The silc_server_remove_from_channels funtion now handles
4935 the channel key re-generation.
4937 * Added `sender' argument to the silc_server_send_notify_on_channels
4938 to not to send the client provided as argument. Affected file
4939 silcd/packet_send.[ch].
4941 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Implemented OPER and SILCOPER commands into the server and
4946 * Added silc_auth_verify and silc_auth_verify_data to verify
4947 the authentication directly from the authentication payload.
4948 It supports verifying both passphrase and public key based
4949 authentication. Affected file lib/silccore/silcauth.[ch].
4951 * Added `hash' field to the SilcIDListData structure. It is the
4952 hash negotiated in the SKE protocol. Affected file is
4955 * Slight redesigning of the SilcAuthPayload handling routines.
4956 Do not send SilcPKCS but SilcPublicKey as argument.
4958 * Implemented the public key authentication support to the
4959 serverconfig. The public key is loaded from the provided path
4960 and saved as authentication data to void * pointer. Thus,
4961 changed the unsigned char *auth_data to void *auth_data;
4963 * Fixed SHUTDOWN command to send the reply before the server
4964 is shutdown. :) Affected file silcd/command.c.
4966 * Fixed fatal bug in CONNECT command. The hostname was invalid
4967 memory and server crashed. Affected file silcd/command.c.
4969 * Fixed fatal bug in CLOSE command. The server_entry became
4970 invalid but was referenced later in the command. Affected file
4973 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Fixed fatal bug in failure packet handling. Server ignored
4976 the failure and thus crashed when it came.
4980 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4983 that the command may be executed only once in (about) 2 seconds.
4984 The old SILC_CF_LAG flag is same but allows command bursts up
4985 to five before limiting.
4987 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4988 server code. Various commands now includes the CF_LAG_STRICT
4989 flag to disallow any kind of miss-use of the command.
4991 * Fixed the silc_buffer_unformat to not to allocate any data
4992 if the length of the data is zero. It used to allocate the
4993 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4995 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Changed the format of AdminConnection configuration section
4998 in the server. Added username of the admin to the format.
4999 Affected files silcd/serverconfig.[ch].
5001 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5002 to return admin configuration data by host, username and/or
5005 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Implemented WHOWAS command to the server. Added the functions:
5009 silc_server_command_whowas_parse,
5010 silc_server_command_whowas_send_reply,
5011 silc_server_command_whowas_from_client and
5012 silc_server_command_whowas_from_server
5014 * Added <Client ID> argument to the WHOWAS command reply. Updated
5015 the protocol specs accordingly.
5017 * Implemented WHOWAS command and command_reply to the client
5020 Implemented the WHOWAS printing on the user interface.
5022 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Added new argument to the WHOWAS command reply, the real name.
5025 It is an optional argument. Updated the protocol specs.
5027 * Added SilcIDCacheDestructor callback that is registered when
5028 the SilcIDCache is allocated. The callback is called when
5029 an cache entry in the ID Cache expires, or is purged from the
5030 cache. Added into lib/silccore/idcache.[ch].
5032 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5033 to destruct the client entries when the cache entry expires.
5034 Other ID Cache's in server and in the client library ignores
5037 * If the ID Cache entry's `expire' field is zero then the entry
5038 never expires. Added boolean `expire' argument to the
5039 silc_idcache_add function in the lib/silccore/idcache.[ch].
5040 If it is TRUE the default expiry value is used.
5042 * Added silc_server_free_client_data_timeout that is registered
5043 when client disconnects. By default for 5 minutes we preserve
5044 the client entry for history - for WHOWAS command.
5046 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added support to the server to enforce that commands are not
5049 executed more than once in 2 seconds. If server receives
5050 commands from client more frequently, timeout is registered
5051 to process the commands. Affected file silcd/command.c.
5052 Added new function silc_server_command_process_timeout.
5054 * Changed NICK_NOTIFY handling in client library to check that
5055 if the client's nickname was changed, so there is no need to
5056 resolve anything from the server.
5058 * Removed error printing from the WHOIS and IDENTIFY commands.
5059 If error occurs then it is ignored silently in the client library.
5060 The application, however, may map the received error to
5061 human readable error string. The application currently maps
5062 the NO_SUCH_NICKNAME error to string.
5064 * Made the command status message public to the application. Moved
5065 them from lib/silcclient/command_reply.c to
5066 lib/silcclient/command_reply.h. The application can map the
5067 received command status to the string with the
5068 silc_client_command_status_message function.
5070 * Added check to the server to check that client's ID is same
5071 as the Source ID in the packet the client sent. They must
5074 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Added dist-bzip hook to the Makefile.am to make bzip2
5077 compressed distributions.
5079 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Server now enforces the maximum length for the nickname and
5082 the channel as protocol specification dictates. 128 bytes for
5083 nickname and 256 bytes for channel name.
5085 * Moved the WHOIS printing to the application. The client libary
5086 does not print out the WHOIS information anymore, the application
5087 must do it. Renamed silc_client_command_reply_whois_print to
5088 the silc_client_command_reply_whois_save.
5090 The client's idle time is also sent to the application now, and
5091 the idle is shown on screen.
5093 * Added silc_client_command_reply_identify_save to save the
5094 received IDENTIFY entries.
5096 * Do not check for channel private keys in message sending and
5097 reception if the channel does not have the PRIVKEY mode set.
5098 Affected file lib/silclient/client_channel.c.
5100 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5103 just surfaced after chaning the JOIN procedure.
5105 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Added silc_client_get_clients_by_list to get client entries
5108 from Client ID list, that is returned for example by JOIN
5109 and USERS command replies. The application should use this
5110 function for example when JOIN command reply is received to
5111 resolve the clients already on the channel (library does not
5112 do that anymore as USERS command reply is not used in the JOIN
5113 procedure anymore). Affected files lib/silcclient/silcapi.h and
5114 lib/silcclient/idlist.c.
5116 * JOIN command reply and USERS command reply returns now SilcBuffer
5117 pointers instead of unsigned char pointers when returning
5118 the client list and mode list.
5120 * Added <Client ID> argument to the JOIN command reply, mainly
5121 for the server to identify for which client the command was
5122 originally sent. Updated protocol specs accordingly.
5124 * Added SilcDlist private_key pointer to the SilcChannelEntry
5125 in the client to support the channel private keys. Affected
5126 file is lib/silcclient/idlist.h.
5128 * Added SilcChannelPrivateKey argument to the function
5129 silc_client_send_channel_message so that application can choose
5130 to use specific private ke if it wants to. If it is not provided,
5131 the normal channel key is used, unless private keys are set.
5132 In this case the first (key that was added first) is used
5133 as the encryption key.
5135 * Implemented the support for channel private key handling.
5136 Implemented the following functions:
5138 silc_client_add_channel_private_key,
5139 silc_client_del_channel_private_keys,
5140 silc_client_del_channel_private_key,
5141 silc_client_list_channel_private_keys and
5142 silc_client_free_channel_private_keys
5144 Affected file lib/silcclient/client_channel.c.
5146 * Added the support for the private keys in the channel message
5147 sending and encryption and in the message reception and
5148 decryption. Affected funtions are
5149 silc_client_send_channel_message and silc_client_channel_message.
5151 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Added SKE's key verify callback to the client library's
5154 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5156 * Removed the statement that server (or router) must send USERS
5157 command reply when joining to the channel so that the client
5158 knows who are on the channel. Instead, the client list and
5159 client's mode list is now sent in the JOIN command reply to the
5160 client who joined channel. This is better solution.
5162 * Added function silc_server_get_users_on_channel and function
5163 silc_server_save_users_on_channel to the silcd/server.[ch].
5165 * Removed function silc_server_command_send_users from the
5168 * Do not show topic on the client library anymore. The topic is
5169 sent in the command reply notify to the application and the
5170 application must show the topic now.
5172 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Added client searching by nickname hash into the IDENTIFY and
5175 WHOIS commands in the server as they were clearly missing from
5176 them. Affected file is silcd/command.c.
5178 * Fixed a bug in private message receiving in the client library.
5179 The remote ID was freed and it wasn't supposed, now it is
5182 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Minor fix to the channel payload; allocate the data area, as it
5185 needs to be of specific length.
5187 * If the key agreement port is zero then the operating
5188 system will define the bound port. Affected files are
5189 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5191 * Added new function silc_channel_payload_decrypt into the file
5192 lib/silccore/silcchannel.[ch].
5194 * Moved the channel message etc, check from silc_packet_decrypt
5195 to applications. The library calls now a generic
5196 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5197 when the packet is either normal or special. This was done to
5198 allow more wide range of checking that was not allowed when
5199 the code was in library. Now applications can do virtually any
5200 checks to the packet and return to the library the decision how
5201 the packet should be processed. Affected files are
5202 lib/silccore/silcpacket.[ch].
5204 Added silc_server_packet_decrypt_check to the server and
5205 silc_client_packet_decrypt_check to the client library.
5207 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5208 to send with specified source and destination information.
5210 * Channel message delivery between routers was broken after the
5211 channel key distribution was fixed earlier. The channel key
5212 was used be to distributed to other routers as well which is not
5213 allowed by the protocol. Now this is fixed and channel keys
5214 really are cell specific and the channel message delivery between
5215 routers comply with the protocol specification.
5217 * Fixed various commands in server to check also the global list
5218 for the channel entry and not just the local list. The affected
5219 file silcd/command.c.
5221 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Added assert()s to buffer formatting and unformatting routines
5224 to assert (if --enable-debug) when error occurs. Affected
5225 file: lib/silcutil/silcbuffmt.c.
5227 * Changed to auto-reconnect to check whether the remote host is
5228 router and register the re-connect timeout if it is. It used
5229 to check that whether we are normal server, but router must do
5230 auto-reconnect with another router as well. Affected file
5233 * Removed the [<key len>] option from CMODE command as the cipher
5234 name decides the key length, nowadays. See the defined ciphers
5235 from the protocol specification.
5237 * Added [<hmac>] option to the CMODE command to define the HMAC
5238 for the channel. Added SILC_CMODE_HMAC channel mode.
5240 * Added [<hmac>] option for the JOIN command so that user can
5241 select which HMAC is used to compute the MACs of the channel
5244 * Added Hmac field to the Channel Message Payload. The integrity
5245 of plaintext channel messages are now protected by computing
5246 MAC of the message and attaching the MAC to the payload. The
5247 MAC is encrypted. Now, it is clear that this causes some
5248 overhead to the size of the packet but rationale for this is that
5249 now the receiver can verify whether the channel message decrypted
5250 correctly and also when private keys are set for the channel the
5251 receiver can decrypt the packet with several keys and check from
5252 the MAC which key decrypted the message correctly.
5254 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5255 lib/silccrypt/silccipher.[ch].
5257 * Added silc_hash_len to return the digest length into the
5258 lib/silcrypt/silchash.[ch].
5260 * Rewrote parts of Silc Channel Payload interface in the
5261 lib/silccore/silcchannel.[ch]. The encode function now also
5262 encrypts the packet and parse function decrypts it.
5264 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Fixed a minor formatting bug in the SKE's key material processing.
5267 It actually might have processed the keys wrong way resulting
5270 * Redefined the mandatory HMAC algorithms and added new algorithms.
5271 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5272 and hmac-md5 truncated to 96 bits. The mandatory is now
5273 hmac-sha1-96. Rest are optional (including the one that used
5274 to be mandatory). Rationale for this is that the truncated HMAC
5275 length is sufficient from security point of view and can actually
5276 make the attack against the HMAC harder. Also, the truncated
5277 HMAC causes less overhead to the packets. See the RFC2104 for
5280 * Added new [hmac] configuration section. The SKE used to use
5281 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5282 is of course wrong. The official names that must be proposed in
5283 the SKE are the ones defined in the protocol specification
5284 (hmac-sha1-96 for example). The user can configure any hmac
5285 using any hash function configured in the [hash] section. At
5286 least, the mandatory must be configured.
5288 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5290 * Added HMAC list to the SKE proposal list. It has now both
5291 hash algorithm list and HMAC list. This makes the protocol
5292 incompatible with previous versions. The SKE now seems to work
5293 the way it is supposed to work, for the first time actually.
5295 * Defined plain Hash algorithms to the protocol specification.
5298 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Implemented support for key agreement packets into the server.
5301 Added functions silc_server_key_agreement and
5302 silc_server_send_key_agreement. Other than these functions,
5303 server has nothing to do with this packet.
5305 * Added support for private message key packets into the server.
5306 Added functions silc_server_private_message_key and
5307 silc_server_send_private_message_key.
5311 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5312 called in the protocol's final callback instead in the END
5313 protocol state. This makes a little more sense and in the same
5314 time in client we can use the same protocol routines for normal
5315 key exchange and to key agreement packet handling as well.
5317 * Added to both client's and server's KE protocol context the
5318 SilcSKEKeyMaterial pointer to save the key material. We will
5319 bring the key material to the protocol's final callback by doing
5320 this. The final callback must free the key material.
5322 * Added SKE's packet_send callback into client's KE protocol
5323 context so that the caller can choose what packet sending function
5324 is used. This way we can use different packet sending when
5325 doing normal SKE when doing key agreement packet handling (in
5326 the key agreement packet handling we do not want to encrypt
5329 * Implemented the responder side of the key agreement routines
5330 in the client. The client can now bind to specified port and
5331 accept incoming key negotiation. The key material is passed
5332 to the application after the protocol is over.
5334 * Implemented the processing of incoming Key Agreement packet
5335 in the client. Added function silc_client_key_agreement to
5338 * Implemented the intiator side of the key agreement routines
5339 in the client. The client can now initiate key agreement with
5340 another remote client. The key material is passed to the
5341 application after the protocol is over.
5343 * Created client_keyagr.c to include all the key agreement
5346 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5347 SILC_TASK_CALLBACK except that it is not static.
5349 * Created client_notify.c and moved the Notify packet handling
5350 from the client.[ch] into that file.
5352 * Created client_prvmsg.c and moved all private message and
5353 private message key routines from the client.[ch] into that file.
5355 * Create client_channel.c and moved all channel message and
5356 channel private key routines from the client.[ch] into that file.
5358 * Changed silc_client_get_client_by_id_resolve to resolve with
5359 WHOIS command instead of IDENTIFY command, in the file
5360 lib/silclient/idlist.c.
5362 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Implemented the SKE's responder side to the Client library.
5366 * When FAILURE is received to the protocol do not trust it
5367 blindly. Register a timeout to wait whether the remote closes
5368 the connection as it should do it, only after that process the
5369 actual failure. This was changed to both client and server.
5371 * Added client_internal.h to include some of the structures
5372 there instead of client.h in lib/silcclient/.
5374 * Added function silc_task_unregister_by_callback to unregister
5375 timeouts by the callback function.
5377 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Some "Incomplete WHOIS info" errors has been appearing on the
5380 log files. Took away the entry->userinfo check from WHOIS
5381 reply sending. The entry->userinfo is now " " if client did not
5382 provide one. I thought this was fixed earlier but something
5383 is wrong still. Let's see if the error still appears.
5385 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Fixed a minor bug in the login when the channel key is
5388 re-generated in the server. It used to generate the key in
5389 wrong order and thus caused problems in the channel traffic.
5391 * Fixed a minor bug in channel key distsribution after
5392 KICK command. The key was not sent to the router even though
5395 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Added silc_ske_process_key_material_data as generic routine
5398 to process any key material as the SILC protocol dictates. The
5399 function is used by the actual SKE library but can be used by
5400 applications as well. This relates to the private message keys
5401 and the channel private keys since they must be processed the
5402 same way the normal SILC session keys. The protocol dictates
5403 this. Affected files: lib/silcske/silcske.[ch].
5405 Added also silc_ske_free_key_material to free the
5406 SilcSKEKeyMaterial structure.
5408 * Defined silc_cipher_set_key function to set the key for
5409 cipher without using the object's method function. The affected
5410 files: lib/silccrypt/silccipher.[ch].
5412 * Implemented silc silc_client_add_private_message_key,
5413 silc_client_add_private_message_key_ske,
5414 silc_client_del_private_message_key,
5415 silc_client_list_private_message_keys and
5416 silc_client_free_private_message_keys functions in the
5419 Added functions silc_client_send_private_message_key to send
5420 the Private Message Key payload and silc_client_private_message_key
5421 to handle incoming Private Message Key payload.
5423 * Added Cipher field to the Private Message Key payload to set
5424 the cipher to be used. If ignored, the default cipher defined
5425 in the SILC protocol (aes-256-cbc) is used.
5427 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Removed lib/silcclient/ops.h file.
5431 Redefined parts of the SILC Client Library API. Created new
5432 file silcapi.h that deprecates the ops.h file and defines the
5433 published Client Library API. Defined also private message key
5434 API and channel private key API into the file.
5436 This is the file that the application must include from the
5437 SILC Client Library. Other files need not be included by
5438 the application anymore.
5440 * Added new key_agreement client operation callback and also
5441 defined the Key Agreement library API for the application.
5443 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5446 is used by clients to request key negotiation between another
5447 client in the SILC network. If the negotiation is started it
5448 is performed using the SKE protocol. The result of the
5449 negotiation, the secret key material, can be used for example
5450 as private message key.
5452 Implemented the Key Agreement payload into the files
5453 lib/silccore/silauth.[ch].
5455 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Redefined ciphers for the SILC protocol. Added some new ciphers
5458 and defined the key lengths for the algorithms. Changed the
5459 code accordingly. The default key length is now 256 bits.
5461 * Fixed SKE key distribution function silc_ske_process_key_material
5462 when the key length is more than 128 bits. The default key
5463 length in SILC is now 256 bits.
5465 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5466 to indicate unsupported algorithm.
5468 * Renamed rijndael.c to aes.c and all functions as well.
5470 * Fixed a long standing channel key setting bug in client library.
5471 Weird that it has never surfaced before.
5473 * Fixed bug in channel deletion. If the entire channel is removed
5474 then it must also delete the references of the channel entry
5475 from the client's channel list as the client's channel entry and
5476 the channel's client entry share same memory.
5478 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Implemented CONNECT and SHUTDOWN commands in the client.
5482 * Implemented CLOSE command to the client.
5484 * Added the function silc_idlist_find_server_by_name into the
5485 files silcd/idlist.[ch].
5487 Added the function silc_idlist_find_server_by_conn into the
5488 files silcd/idlist.[ch].
5490 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * DIE command was renamed to SHUTDOWN. Updated the both code
5495 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5496 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5498 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5501 * Added function silc_server_create_connection function to create
5502 connection to remote router. My server implementation actually
5503 does not allow router to connect to normal server (it expects
5504 that normal server always initiates the connection to the router)
5505 so the CONNECT command is only good for connecting to another
5508 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5511 or some other client was kicked from the channel.
5513 Implemented the handling of the notify type to both client
5516 Implemented silc_server_send_notify_kicked to send the KICKED
5517 notify. It is used to send it to the server's primary router.
5519 * Implemented the KICK command into server and client.
5521 * Added `query' argument to the silc_idlist_get_client function
5522 to indicate whether to query the client from server or not if
5525 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5526 to indicate that the client is not channel founder.
5530 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Removed the rng context from SilcPacketContext structure and
5533 changed that the packet routine uses the Global RNG API.
5535 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Added support for quit message that client can "leave" on the
5538 channel when it quits the SILC. It is ditributed inside the
5539 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5541 Added silc_server_free_client_data that will take the
5542 signoff message as argument.
5544 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5546 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Updated parts of the protocol specification to keep it up
5551 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5554 payloads in one packet.
5556 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5557 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5558 use now the new List flag.
5560 * Also deprecated the following packet types: REPLACE_ID,
5561 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5563 * Added list support for Notify packet in server.
5565 * Added silc_server_send_notify_channel_change to send the
5566 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5567 the silc_server_send_replace_id.
5569 * Added silc_server_send_notify_nick_change to send the
5570 NICK_CHANGE notify type. Deprecates the function
5571 silc_server_send_replace_id.
5573 * Added silc_server_send_notify_join to send the JOIN notify type.
5574 Deprecates the function silc_server_send_new_channel_user.
5576 * Added silc_server_send_notify_leave to send LEAVE notify type.
5577 Deprecates the function silc_server_send_remove_channel_user.
5579 * Added silc_server_send_notify_cmode and
5580 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5581 types. Deprecates the silc_server_send_set_mode function.
5583 * Added SERVER_SIGNOFF notify type to indicate that server has
5584 quit. This means that all clients on the channel from that
5585 server will drop. This can be also used when netsplit happens.
5587 Deprecated REMOVE_ID packet type since it is not needed anymore
5590 Added silc_server_send_notify_server_signoff to send the
5591 SERVER_SIGNOFF notify type. Deprecates the function
5592 silc_server_send_remove_id.
5594 Added also silc_server_send_notify_signoff to send the
5595 SIGNOFF notify type.
5597 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5598 SILC protocol from this day on. Changed the protocol
5599 specification as well.
5601 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5602 notify type. It is used between routers to notify about
5603 topic changes on a channel.
5605 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5608 * Partly updated the protocol specification to comply with the
5609 changes now made. It is still though a bit outdated.
5611 * The JOIN notify type now takes one extra argument <Channel ID>.
5612 The packet used to be destined to the channel but now the
5613 JOIN type may be sent as list thus it is impossible to
5614 destine it to any specific channel. By adding this argument
5615 it is again possible.
5617 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Added CREDITS file. The CHANGES and CREDITS file will appear
5620 in the distribution as well.
5622 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5625 types in the server's silcd/packet_receive.c.
5627 * Implemented CMODE and CUMODE to work in router environment.
5629 * Fixed minor encoding and decoding buglet from the
5630 lib/silccore/silcmode.c.
5632 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5635 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5637 * Changed all SilcConfigServer* and silc_config_server* to
5638 SilcServerConfig* and silc_server_config*, respectively.
5641 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Associated the ID (client or server ID) to the Authentication
5644 Payload to avoid any possibility of forging. Updated the
5645 protocol specification and the code accordingly.
5647 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * The RSA key length is now save to the RsaKey context in the
5650 key generation process in lib/silccrypt/rsa.c. The key length
5651 is now used to figure out the maximum size of the block allowed
5652 to be encrypted/signed.
5654 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5655 is equivalent to the silc_mp_mp2bin but does not allocate any
5658 * Changed silc_mp_mp2bin API to take length argument. If it is
5659 non-zero then the buffer is allocated that large. If zero, then
5660 the size is approximated using silc_mp_sizeinbase, which however
5663 * Created Global RNG API which is global RNG that application can
5664 initialize. After initializing, any routine anywhere in the
5665 code (including library) can use RNG without allocating a new
5666 RNG object. This was done to allow this sort of use of the
5667 RNG in code that has no chance to allocate RNG object. All
5668 applications currently allocate this and many routines in the
5669 library use this. Affected file lib/silccrypt/silcrng.[ch].
5671 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5672 it to use the Global RNG API.
5674 * Defined Authentication Payload into protocol specification that
5675 is used during SILC session to authenticate entities. It is
5676 used for example by client to authenticate itself to the server
5677 to obtain server operator privileges.
5679 Implemented this payload into the lib/silccore/silcauth.[ch].
5680 Implemented also routines for public key based authentication
5681 as the new protocol specification dictates.
5683 Moved definitions of different authentication methods from
5684 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5686 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5687 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5688 silc_pkcs_verify_with_hash functions into the file
5689 lib/silccrypt/silcpkcs.[ch].
5691 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * The client entry's userinfo pointer must be always valid.
5694 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5695 will fail since it requires the userinfo. Now, the userinfo
5696 is allocated as "" if actual userinfo does not exist. Actually,
5697 it must exist and it is totally Ok to drop client connections
5698 that does not announce the userinfo. However, we will make
5699 this workaround for now.
5701 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5702 to return the remote port by socket.
5704 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5707 SILC_SERVER_PENDING_EXEC and added an new macro
5708 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5709 data or when error occurs while processing the pending command.
5711 Added new argument `destructor' into silc_server_command_pending
5712 and to the SilcServerCommandPending object. This destructor is
5713 now called after calling the pending callback or if error occurs
5714 immediately. If error occurs the actual pending callback won't
5715 be called at all - only the destructor. The destructor may be
5716 NULL if destructor is not needed.
5718 All this applies for client library code as well. Similar
5719 changes were made there as well for the pending commands.
5721 In the client, the application must now allocate the
5722 SilcClientCommandContext with the silc_client_command_alloc
5725 * Added reference counter to the SilcServerCommandContext. Added
5726 function silc_server_command_alloc and silc_server_command_dup
5729 Same type of functions added to the client library for the same
5732 * Removed the cmd_ident from IDListData away since it is now
5733 global for all connections. It is the command identifier used
5734 in command sending and with pending commands. The affected file
5737 * Added reference counter to the SilcSocketConnection objecet to
5738 indicate the usage count of the object. The object won't be
5739 freed untill the reference counter hits zero. Currently only
5740 server uses this, and client ignores it. The client must be
5741 set to use this too later. The affected files are
5742 lib/silccore/silcsockconn.[ch]. Added also the function
5743 silc_socket_dup to increase the reference counter.
5745 This was mainly added because it is possible that the socket
5746 is removed underneath of pending command or other async
5747 operation. Now it won't be free'd and proper DISCONNECTING
5748 flags, etc. can be set to avoid sending data to connection that
5749 is not valid anymore.
5751 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5752 the connection. After that it sets SILC_SET_DISCONNECTED.
5753 It is, however, possible that the socket data is not still freed.
5754 The silc_server_packet_process now checks that data is not
5755 read or written to connection that is DISCONNECTED. The socket
5756 get's freed when the reference counter hits zero.
5758 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Changed the client operation API: channel_message operation's
5761 `sender' is now the client entry of the sender, not the nickname
5762 and the `channel' is the channel entry, not the channel name.
5764 In the private_message operation the `sender' is now also the
5765 client entry of the sender not the nickname.
5767 Affected file is lib/silcclient/ops.h and all applications
5768 using the client operations.
5770 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Moved the calling of ops->connect() from connect_to_server_final
5773 into receive_new_id functin since that is the point when the
5774 client is actually allowed to send traffic to network. The
5775 affected file is lib/silcclient/client.c.
5777 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5780 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5781 (if needs broadcasting) instead of broadcasting the packets one
5782 by one which would make a burst in the network traffic.
5784 * Added `broadcast' argument to the functions in silcd/server.[ch]
5785 silc_server_create_new_channel[_with_id] to indicate whether
5786 to send New Channel packet to primary router.
5788 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added new function into the silcd/server.[ch] files:
5791 silc_server_create_new_channel_with_id to create new channel with
5792 already existing Channel ID.
5794 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5795 lib/silccore/silcpacket.h. This packet is used t send list of
5796 Set Mode payloads inside one packet. Server uses this to set
5797 the modes for the channels and clients on those channels, that it
5798 announced to the router when it connected to it. The protocol
5799 specification has been updated accordingly.
5801 * The silc_server_new_channel did not handle the packet coming
5802 from normal server as it normally does not send that. However,
5803 when it announces its channels it does send it. Implemented
5804 the support for that.
5806 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5807 into the file lib/silccore/id.h.
5809 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Fixed memory leaks in the functions silc_idlist_del_client,
5812 silc_idlist_del_channel and silc_idlist_del_server in the file
5813 silcd/idlist.c. All of those leaked like a sieve.
5815 * Fixed some small memory leaks in the client's function
5816 silc_client_notify_by_server.
5818 * Added functions into silcd/server.c: silc_server_announce_clients,
5819 silc_server_announce_channels and silc_server_announce_server.
5820 These functions are used by normal and router server to announce
5821 to its primary router about clients, channels and servers (when
5822 router) that we own. This is done after we've connected to the
5825 These functions effectively implements the following packet types:
5826 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5827 and SILC_PACKET_NEW_ID_LIST.
5829 * Added new functions into the silcd/packet_receive.[ch]:
5830 silc_server_new_id_list, silc_server_new_channel_list and
5831 silc_server_new_channel_user_list to handle the incoming
5832 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5834 * Added support of changing Channel ID in the function
5835 silc_server_replace_id. If the server that announces a channel
5836 to the router already exists in the router (with same name but
5837 with different Channel ID), router is responsible to send
5838 Replace ID packet to the server and force the server to change
5839 the Channel ID to the one router has.
5841 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5842 client that the Channel ID has been changed by the router. The
5843 normal server sends this to the client. Client must start using
5844 the new Channel ID as the channel's ID.
5846 Implemented handling of this new type into lib/silcclient/client.c
5847 into the function silc_client_notify_by_server.
5849 * Added new function silc_idlist_replace_channel_id into the files
5850 silcd/idlist.[ch] to replace the Channel ID.
5852 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Call silc_server_command_identify_check always when processing
5855 the IDENTIFY command in silcd/command.c
5857 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5860 send keepalive packets. The packet can be sent by clients,
5861 servers and routers.
5863 Added function silc_socket_set_heartbeat into the file
5864 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5865 If not set, the heartbeat is not performed. The actual
5866 heartbeat is implemented in the low level socket connection
5867 library. However, application is responsible of actually
5870 Added silc_server_send_heartbeat to send the actual heartbeat
5871 packet into silcd/packet_send.[ch]. Server now performs
5872 keepalive with all connections.
5874 * Added silc_task_get_first function into lib/silcutil/silctask.c
5875 to return the timeout task with shortest timeout. There was a bug
5876 in task unregistration that caused problems. TODO has been
5877 updated to include that task system must be rewritten.
5879 * The client library will now resolve the client information when
5880 receiving JOIN notify from server for client that we know but
5881 have incomplete information.
5883 * Rewrote parts of silc_server_remove_from_channels and
5884 silc_server_remove_from_one_channel as they did not remove the
5885 channel in some circumstances even though they should've.
5887 * Encryption problem encountered in server:
5889 The LEAVE command used to send the Channel Key packet to the
5890 router immediately after generating it. However, the code
5891 had earlier sent Remove Channel user packet but not immediately,
5892 ie. it was put to queue. The order of packets in the router
5893 was that Channel Key packet was first and Remove Channel User
5894 packet was second, even though they were encrypted in the
5895 reverse order. For this reason, MAC check failed. Now, this
5896 is fixed by not sending the Channel Key packet immediately but
5897 putting it to queue. However, this is more fundamental problem:
5898 packets that are in queue should actually not be encrypted
5899 because packets that are sent immediately gets encrypted
5900 actually with wrong IV (and thus MAC check fails). So, packets
5901 that are in queue should be encrypted when they are sent to
5902 the wire and not when they put to the queue.
5904 However, the problem is that the current system has not been
5905 designed to work that way. Instead, the packet is encrypted
5906 as soon as possible and left to the queue. The queue is then
5907 just purged into wire. There won't be any fixes for this
5908 any time soon. So, the current semantic for packet sending
5911 o If you send packet to remote host and do not force the send
5912 (the packet will be in queue) then all subsequent packets to the
5913 same remote host must also be put to the queue. Only after the
5914 queue has been purged is it safe again to force the packet
5917 o If you send all packets immediately then it safe to send
5918 any of subsequent packets through the queue, however, after
5919 the first packet is put to queue then any subsequent packets
5920 must also be put to the queue.
5922 Follow these rules and everything works fine.
5924 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added new function silc_server_remove_clients_by_server to
5927 remove all client entries from ID list when the server connection
5928 is lost. In this case it is also important to invalidate all
5929 client entires as they hold the invalid server entry. This
5930 fixes fatal bug when server has lost connection and will reconnect
5933 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Made some sanity checks to silc_server_daemonise like to check
5936 whether the requested user and group actually exists.
5938 * Added sanity check to SKE's silc_ske_responder_finish to check
5939 that the public and private key actually is valid.
5941 * Invalidate the client's nickname when receiving Replace ID
5942 packet and the Client ID is being replaced. This means that the
5943 server will query the nickname if someone needs it (client)
5946 * Sort the ID Cache in client library when the ID Cache data
5947 has changed (needs sorting).
5949 * Do not allow for SILC client to create several connections to
5950 several servers. The client does not support windows right now
5951 and generating multiple connections causes weird behaviour.
5953 Irssi-silc client does support windows and can handle several
5954 connections without problems, see: www.irssi.org and SILC plugin.
5956 * Fixed some places where client was added to the IDList. The
5957 rule of thumb is following (in order to get everything right):
5958 If the client is directly connected local client then the
5959 `connection' argument must be set and `router' argument must be
5960 NULL to silc_idlist_add_client function. If the client is not
5961 directly connected client then the `router' argument must
5962 bet set and the `connection' argument must be NULL to the
5963 silc_idlist_add_client function.
5965 * The funtion silc_server_packet_send_local_channel actually did
5966 not check whether the client was locally connected or not. It
5967 does that now. Fixed a bug related to LEAVE command.
5969 * Fixed Remove Channel User payload parsing bug in server's
5970 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5972 * The server's silc_server_save_channel_key now checks also the
5973 global ID list for the channel as it might not be in the local
5974 list. Fixed a bug related to LEAVE command.
5976 * Is this the end of the [<unknown>] buglet that has been lurking
5977 around for a long time? A little for loop fix in server's
5978 silc_server_command_whois_parse that is used by both IDENTIFY
5979 and WHOIS command. At least, this was a clear bug and a cause
5980 of one type of [<unknown>] buglet.
5982 * WHOIS and IDENTIFY commands call the function
5983 silc_server_command_[whois/identify]_check function even if
5984 we are not router server.
5986 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Added --with-gmp configuration option. If set the GMP
5989 is always compiled in the SILC source tree. If not set then
5990 it is checked whether the system has the GMP3 installed. If
5991 it has then the GMP won't be compiled (the system's headers
5992 and library is used), if it doesn't have it then the GMP is
5993 compiled in the SILC source tree.
5995 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Changed RSA private exponent generation to what PKCS #1
5998 suggests. We try to find the smallest possible d by doing
5999 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6000 not security fix but optimization.
6002 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Added new config entry [Identity] to fork the server and run
6005 it as specific user and group. A patch from Bostik.
6007 * Imported Dotconf configuration library into lib/dotconf.
6008 This will be used to create the SILC configuration files later.
6009 It will appear in the distsribution after this commit.
6011 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * A big code auditing weekend happening. Auditing code for
6014 obvious mistakes, bugs and errors. Also, removing any code
6017 Removed files for being obsolete:
6019 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6020 inline in the file lib/silcutil/silcbuffer.h)
6022 o lib/silcutil/silcbufutil.c (the header has inline versions)
6024 Changed code to fix possible error conditions:
6026 o The buffer formatting routines now check that the destination
6027 buffer really has enough space to add the data. This applies for
6028 both buffer formatting and unformatting
6029 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6030 unformatting was changed to accomodate following rules:
6031 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6032 sent to the function while XXX_*STRING will not allocate or copy
6033 the data into the buffer. Instead it sets the pointer from the
6034 buffer into the pointer sent as argument (XXX_*STRING used to
6035 require that the pointer must be allocated already). This change
6036 makes this whole thing a bit more consistent and more optimized
6037 (note that the data returned in the unformatting with XXX_*STRING
6038 must not be freed now). The routines return now -1 on error.
6040 o Tried to find all code that use buffer_format and buffer_unformat
6041 and added return value checking to prevent formatting and
6042 especially unformatting errors and possible subsequent fatal
6045 o Changed ske->x and ske->KEY to mallocated pointers in
6046 lib/silcske/silcske.h. Fixed possible data and memory leak.
6048 o Added return value checking to all *_parse* functions. Fixed
6049 many memory leaks as well.
6051 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6052 so that buffer overflows would not happen. All code now also
6053 checks the return value as it can fail.
6055 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6057 * Added reconnection support to server if the normal server looses
6058 its connection to the router (for example if router is rebooted).
6059 The server performs normal reconnection strategy implemented
6060 to the server. Affected file silcd/server.c.
6062 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Added new packet type SILC_PACKET_SET_MODE that is used to
6065 distribute the information about changed modes (for clients,
6066 channels and clients channel modes) to all routers in the
6067 network. Updated the protocol specification accordingly.
6069 Added functions into silcd/packet_send.c and
6070 silcd/packet_receive.c: silc_server_send_set_mode,
6071 silc_server_set_mode.
6073 Added new files silcmode.[ch] into lib/silccore that implements
6074 the encoding and decoding of Set Mode Payload. Added new type
6075 SilcSetModePayload. Moved the definitions of different modes
6076 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6078 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Oops, a little mistake in server's connection authentication
6081 protocol. The protocol is not ended with FAILURE but with
6082 SUCCESS if the authentication is Ok. :) Affected file is
6085 * Implemented NICK_CHANGE notify handling in server in the file
6086 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6087 the local clients on the channel. After the changing nickname
6088 in router environment snhould work and the [<unknown>] nickname
6089 should appear no more.
6091 The silc_server_replace_id function that receives the Replace ID
6092 payload now sends the NICK_CHANGE notify type also in the file
6093 silcd/packet_receive.c
6095 * Changed WHOIS and IDENTIFY command to support the maximum amount
6096 of arguments defined in protocol specs (3328 arguments). This
6097 fixed a bug that caused problems when there were more than three
6100 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Added extra parameter, command identifier, to the
6103 silc_client_send_command so that explicit command identifier
6106 Changed that ID list routines uses specific command identifier
6107 when sending WHOIS/IDENTIFY requests to the server so that they
6108 can be identified when the reply comes back.
6110 Affected files lib/silcclient/command.[ch],
6111 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6113 * Added `sender' argument to silc_server_packet_send_to_channel
6114 to indicaet the sender who originally sent the packet to us
6115 that we are now re-sending. Ignored if NULL. Affected file
6116 silcd/packet_send.[ch].
6118 * Added some server statistics support in silcd/server_internal.h
6119 SilcServerStatistics structure and around the server code. Also
6120 send some nice statistics information when client is connecting
6123 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Fixed channel ID decoding in server's JOIN command reply in
6126 silcd/command_reply.c
6128 * Fixed braodcasting of replace ID payload to not to send it if
6129 we are standalone server in silcd/packet_receive.c.
6131 * Fixed all channel message sending routines to not to send
6132 packets to clients that has router set, since they are routed
6133 separately in the same function earlier. Affects file
6134 silcd/packet_send.c and all channel packet sending functions.
6136 * In USERS reply, res_argv[i] are not allocated, the table
6137 is allocated. Thus changed that free the table, not its
6140 * In server's whois_check and identify_check if the client is
6141 locally connected do not send any WHOIS commands - they are not
6144 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Fixed some minor bugs in client when sending WHOIS command. The
6147 arguments was in wrong order.
6149 * Removed statis function add_to_channel from server in
6150 silcd/command.c that was previously used with the joining but
6153 * Tested USERS command in router environment successfully with two
6154 routers, two servers and two clients.
6156 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Reorganized the USERS command and command reply in client library
6159 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6160 When the command is given by user we register a pending command
6161 callback that will reprocess the command after the reply has been
6162 received from the server. When reprocessing the packet we then
6163 display the information. Thus, the USERS information is displayed
6164 now in the command callback instead of in the command reply
6165 callback. The processing of the command is same as previously
6166 when server has sent the command reply in the JOINing process.
6168 * Added to USERS command in silcd/command_reply.c to join the client,
6169 we didn't use to know about, to the channel after we've created
6170 a client entry for it. Also, for clienet we did know already still
6171 check whether it is on the channel or not and add it if not.
6173 * Removed silc_server_command_join_notify as the function and its
6176 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Changed the client's pending command handling to the same as the
6179 server's pending command handling. It is also now possible to
6180 execute command reply functions from other command reply
6181 function as the function callbacks for commands and command
6182 replies are one and same. The pending commands are not static
6183 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6184 in client connection context. Thus, pending commands are server
6185 connection specific as it is convenient.
6187 Changed the function silc_client_command_pending and
6188 silc_client_command_pending_del and added new function
6189 silc_client_command_pending_check. Removed the
6190 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6193 * Added cmd_ident, current command identifier, to the client
6194 connection context in lib/silcclient/client.h to keep track on
6195 command identifiers used in command sending. Client's command reply
6196 function handling now supports the mandatory command identifiers.
6198 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6199 funtions in client to fully support pending command callbacks.
6201 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6202 as one of the arguments to the application in the command reply
6205 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6206 before first releasing SILC but came back. Now it is removed again
6207 and should come back nomore. The FORWARDED flag was used only
6208 by the JOINing procedure by forwarding the command packet to router.
6209 Now, the JOINing procedure has been changed to more generic (due
6210 to various router environment issues) and FORWARDED is not needed
6211 anymore for anything. The protocol specification is yet to be
6214 Now, removed silc_server_packet_forward from server and the flag
6215 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6217 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * Renamed NAMES command to USERS command. The NAMES was named that
6220 due to historical reasons. Now it is renamed. Also, rewrote
6221 parts of the USERS command. The nickname list is not sent anymore
6222 by the server. Only Client ID and mode lists are sent in the USERS
6223 command. Changed this also to the protocol specification.
6225 The client now resolves the names and stuff after it receives
6226 the USERS list from the server when joining to the channel.
6228 * WHOIS and IDENTIFY commands has been changed to support multiple
6229 Client ID's per command. One can now search for multiple users
6230 in the network by sending only one WHOIS or IDENTIFY command.
6231 Changed the code and the protocol specifications.
6233 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6234 uses silc_server_command_whois_parse to parse the request. */
6236 * If normal server, do not parse the WHOIS and IDENTIFY requests
6237 before sending it to the router. Saves some time.
6239 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Fixed JOIN command on client library. Wrong number of arguments
6242 used to crash the client.
6244 * Added silc_server_channel_has_global function to check whether
6245 channel has global users or not.
6247 * Added silc_server_channel_has_local function to check whether channel
6248 has locally connected clients on the channel.
6250 * The silc_server_remove_from_one_channel now checks whether the
6251 channel has global users or not after given client was removed from
6252 the channel. It also checks whether the channel has local clients
6253 on the channel anymore. If it does not have then the channel entry
6254 is removed as it is not needed anymore.
6256 * The silc_server_notify now checks on JOIN notify whether the joining
6257 client is one of locally connected or global. If it is global then
6258 the channel has now global users on the channel and that is marked
6259 to the channel entry. Also, it now saves the global client to
6260 global list who is joining and JOINs it to the channel. This is
6261 for normal server, that is.
6263 Changed silc_server_send_notify_on_channel,
6264 silc_server_packet_relay_to_channel and
6265 silc_server_packet_send_to_channel check if we are normal server
6266 and client has router set (ie. global client) do not send the
6267 message to that client, as it is already routed to our router.
6269 * Implemented LEAVE notify type handling in silc_server_notify
6272 * Tested LEAVE command in router environment successfully. Tested
6273 with two routers, two servers and two clients.
6277 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6279 * Implemented SIGNOFF notify type handling in silc_server_notify
6282 * silc_server_remove_id now removes the client entry from all channels
6283 it has joined and thusly sends SIGNOFF notify type.
6285 * Rewrote the NAMES list generation in server by removing two excess
6286 loops. The lists are created now inside one loop.
6288 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * silc_server_remove_channel_user checks now also global list
6291 for channel and client.
6293 * silc_server_new_channel_user checks now both local and global
6294 list for channel and client. Fixed a bug in client id decoding.
6295 Used to decode wrong buffer.
6297 * silc_server_channel_message checks now both local and global
6298 list for channel entry.
6300 * Tested channel joining (hence JOIN) in router environment
6301 successfully. Tested with two routers, two servers and two
6304 * Tested channel message sending in router environment successfully.
6306 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Added silc_server_save_channel_key into server.[ch] to save the
6309 received channel key in Channel Key payload processing. It is
6310 also used in JOIN command reply handling.
6312 Equivalent function silc_client_save_channel_key added into
6313 client.[ch] into client library.
6315 * Changed JOIN command reply to send information whether the channel
6316 was created or not (is existing already) and the channel key
6317 payload. Changed protocol specs accordingly.
6319 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6320 the request was sent by ID and not by nickname. Crashed on
6323 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6326 now correctly save the received data.
6328 * silc_server_free_sock_user_data now notifies routers in the
6329 network about entities leaving the network.
6331 At the same time implemented functions silc_server_remove_id
6332 and silc_server_send_remove_id to receive and send REMOVE_ID
6333 packets. The packet is used to notify routers in the network
6334 about leaving entities. The ID removed will become invalid in
6337 * Added function silc_idlist_del_server into server. Removes and
6338 free's server entry from ID list.
6340 * silc_server_private_message function now checks, if we are router,
6341 that the destination ID really is valid ID, naturally.
6343 * In router when NEW_ID packet is received (for new client) the
6344 hash of the Client ID is saved in the ID Cache but the
6345 client->nickname is set to NULL, instead of putting the hash
6348 IDENTIFY command now also checks that client->nickname must be
6349 valid. If it is not if will request the data from the server who
6350 owns the client. Added new function
6351 silc_server_command_identify_check.
6353 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6354 to set the command to already allocated Command Payload.
6356 * Tested private message sending in router environment with two
6357 routers, two servers and two clients. Fixed minor bugs and now
6360 * Fixed segfault from client's NAMES command. Used to crash if
6363 * Forwarded packets must not be routed even if it is not destined
6364 to the receiver. Changed server code comply with this.
6366 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Added `require_reverse_mapping' boolean value to ServerParams
6369 structure. If TRUE (not default) the server will require that
6370 the connecting host has fully qualified domain name.
6372 If the reverse mapping is not required and hostname could not be
6373 found the IP address is used as hostname.
6375 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6377 * Implemented version string checking to both client and server.
6378 The check is incomplete currently due to the abnormal version
6379 strings used in development version of SILC.
6381 * Changed all command functions in server to use the new
6384 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * Changed char *data to unsigned char *data in ID Cache system to
6387 support binary data as ID Cache data. Changed code to support
6388 binary data in lib/silccore/idcache.c.
6390 * Renamed silc_server_packet_relay_command_reply to
6391 silc_server_command_reply as it is normal packet receiving
6392 function. Rewrote the function to accept command replys for
6393 servers and not only for clients.
6395 * Mark remote router always as registered server if we are connecting
6396 to it. Otherwise, commands sent by the router to us are ignored.
6398 * All ID List find routines now returns the ID Cache Entry pointer
6399 as well if requested.
6401 * WHOIS command works now in router environment, tested with two
6402 routers, two servers and two clients.
6404 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6405 in router environment (as it is almost equivalent to WHOIS) but
6406 hasn't been tested thoroughly. Added new functions:
6408 silc_server_command_identify_parse
6409 silc_server_command_identify_send_reply
6410 silc_server_command_identify_from_client
6411 silc_server_command_identify_from_server
6413 * Disabled route cache adding because adding two different ID's with
6414 same IP replaces the old cache entry thus giving wrong route.
6415 The entry->router->connection is always the fastest route anyway
6416 so route cache may not be needed. Of course, new routes maybe
6417 established after receiving the ID when the entry->router->connection
6418 might not be anymore the most optimal.
6420 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Add route cache for received ID for fast routing.
6424 * Added silc_server_packet_route to route received packet on router
6425 that is not destined to us.
6427 * Renamed silc_server_get_route to silc_server_route_get.
6429 * Added id_string and id_string_len fields into SilcServer to
6430 include encoded ServerID for fast comparing without excess
6431 encoding of the ID's.
6433 * Cleaned up WHOIS command on server side. Added following static
6436 silc_server_command_whois_parse
6437 silc_server_command_whois_check
6438 silc_server_command_whois_send_reply
6439 silc_server_command_whois_from_client
6440 silc_server_command_whois_from_server
6442 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6443 arguments in command replies. All command functions should be
6444 updated to use this macro.
6446 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Minor typo fixes on command reply handling on server.
6450 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added silc_server_command_add_to_channel internal routine to add
6453 the client to the channel after router has created the channel and
6454 sent command reply to the server.
6456 * Added generic silc_server_send_command to send any command from
6459 * Use static buffer with ID rendering instead of duplicating data.
6461 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Fixed a channel user mode bug when joining to a channel server gave
6464 everybody channel founder rights, oops.
6466 * We mark ourselves as the router of the incoming server connection
6467 if we are router ourselves. This way we can check in some packet
6468 sending functions whether it is locally connected server. For
6469 incoming router connections we put NULL.
6471 * For router sending packets locally means now always sending the
6472 packet cell wide; to local clients and local servers. For normal
6473 server sending packet locally means sending it to only local
6476 * Fixed the JOIN command to really work in router environment. If the
6477 channel is created it is always created by the router. Router is
6478 also responsible of making the initial joining to the channel,
6479 sending JOIN notify to the sending server and distributing
6480 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6481 does not exist server doesn't do anything else but forward the
6482 command to the router which performs everything.
6484 * Added silc_server_send_channel_key function to send the Channel Key
6487 * Added silc_server_create_channel_key to create new channel key. The
6488 channel key is now re-generated everytime someone joins or leaves
6489 a channel, as protocol dictates. Note: channel->key_len is the
6492 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6495 packet_receive.[ch] to separate packet sending and receiving
6496 routines. The server.[ch] now includes everything else including
6497 actual packet processing (writing and reading data) and other
6500 Renamed silc_server_private_message_send_internal to
6501 silc_server_send_private_message. The routine is still though
6502 used only to relay private messages as server does not send
6503 private messages itself.
6505 Renamed silc_server_new_channel to silc_server_create_new_channel
6506 and added new function sicl_server_new_channel that handles the
6507 incoming New Channel packet. Added also new sending function
6508 silc_server_send_new_channel to send New Channel Payload.
6510 * Added new function silc_server_notify to process incoming notify
6511 packet to the server/router. Server may then relay the notify
6512 to clients if needed.
6514 * Added new function silc_server_new_channel_user to process incoming
6515 New Channel User packet. Router will redistribute the packet and
6516 send JOIN notify to its local clients and locally connected servers
6517 if needed. Normal server will send JOIN notify to its local client
6518 on same channel when received this packet. Added also corresponding
6519 sending function silc_server_send_new_channel_user to sent the
6522 * Added boolean route argument to send_notif_to_channel and
6523 packet_send_to_channel functions to attempt to route the packet
6524 if it is TRUE and send only locally if it is FALSE.
6526 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * silc_server_replace_id now broadcasts the received replace ID
6529 packet if it is not broadcast packet already. The router must
6530 broadcast to inform other routers about changed ID.
6532 * Added backpointer to server's router into SilcServer context in
6533 silcd/server_internal.h.
6535 * Fixed silc_server_packet_broadcast to send correct broadcast
6538 * The channel key is now distributed to the local client as soon
6539 as it is received from the router (in router environment) so that
6540 no other packet may be sent for the channel until client has
6543 * silc_server_remove_channel_user now broadcasts the received
6544 Remove Channel User packet if it is not broadcast packet already.
6545 The router must broadcast to inform other routers about removed
6548 * Added users field into SilcPacketContext that is a reference count
6549 of the context. One can increase the reference count by calling
6550 silc_packet_context_dup which is now changed to just increase the
6551 reference count instead of duplicating the data. The reference
6552 count is decresed by calling silc_packet_context_free that will
6553 free the data after the reference count hits zero.
6555 For now on the packet context and everything allocated into it
6556 (including the raw packet from network) must be freed by calling
6557 the new silc_packet_context_free function. Added also new function
6558 silc_packet_context_alloc that must be used now to allocate the
6559 context. This also means that if a routine is asynchronous from
6560 silc_[client/server]_packet_parse_type the packet context must
6561 be duplicated by calling silc_packet_context_dup. Otherwise it
6562 gets free'd after silc_[client/server]_packet_parse_type returns.
6563 Also, one must remember that if packet is duplicated then its
6564 reference count must be decresed by calling the free function as
6565 many times as it was duplicated.
6567 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6568 from both client and server.
6570 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Made joining to a channel working in router environment.
6574 * Cleaned up JOIN command on server side and create function
6575 silc_server_command_join_channel internal routine to make the
6578 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Changed silc_command_pending list to SilcDList. Also, added
6581 `ident' field to SilcServerCommandPending structure to identify
6582 the reply and to call correct callback.
6584 Added silc_server_command_pending_check function to replace the
6585 corresnponding macro. The silc_command_pending list is not
6588 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6589 to set identifier to previously allocated Command Payload. It
6590 is used to set identifier for command when resending Command
6593 * Added silc_command_payload_encode_payload to encode Command
6594 Payload buffer from SilcCommandPayload structure.
6596 * Added silc_argument_payload_encode_payload to encode Argument
6597 payload buffer from SilcArgumentPayload structure.
6599 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Changed WHOIS command to support router connection on server side.
6602 The whois request is always sent to router unless the server is
6603 standalone server. After server has received the reply from the
6604 router will it send the reply to the client.
6606 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6607 broadcast received broadcast packet. The function is used only
6608 by router. The broadcast packet is always sent to the router's
6611 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6612 render given ID to printable string, for log files for example.
6614 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6616 * Made basic router to router connections working. At least they
6617 can now connect to each other but nothing really works the way
6618 they are supposed - yet.
6620 * Added new initiator token to RouterConnection configuration
6621 file in silcd/serverconfig.[ch]. It is used to tell whether we
6622 are the initiator to the remote router or whether we'll expect
6623 the other end to connect.
6625 * Moved registering of listener task to silc_server_init, hence
6626 the server starts listenning as soon as it is run, even if it
6627 does not have connections to other routers. Let's see how well
6630 * Changed default connection retry timeouts for more suitable in
6633 * Removed cipher and such arguments from silc_idlist_add_client
6634 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6635 Added new function silc_idlist_add_data to add the keys and stuff
6638 * Added SilcIDListData structure and added it to SilcClientEntry
6639 and SilcServerEntry as their first field in the structure. This
6640 way we can explicitly cast the ID entries to the SilcIDListData
6641 structure and get common data for the entries. In past, we had
6642 to first check what type of connection it is and then cast it to
6643 correct ID entry type. Now, we can directly cast the opaque
6644 pointer to the SilcIDListData (no matter what ID entry it actually
6645 is) and get the data needed.
6647 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6650 in some circumstances even if threre were timeout tasks, though not
6651 IO tasks, but tasks anyway. Now fixed.
6653 * Defined SilcServerConnection structure to hold connection specific
6654 stuff about directly connected servers and routers. The definition
6655 is currently in silcd/server_internal.h. I thought about having
6656 a bit more important role fro this struct but for now it is used
6657 only when connecting to other server (or router actually).
6659 * Added connecting retry support in server when connecting to
6660 router(s). The retry feature implement exponential backoff
6661 algorithm. Also, added SilcServerParams structure to hold default
6662 parameters for server. For now, it include these retry settings
6663 and are hard coded. After server is moded to be as Silc Server
6664 Library this structure will be more important.
6666 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Changed client librarys channel->clients table to SilcList and
6669 changed code accordingly.
6671 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Changed client's channel table to SilcList and changed code
6674 accordingly. Also changed SilcChannelClientEntry to include back-
6675 pointer to the channel so that client entry can use that structure
6676 as list as well and we have fast cross-reference to the channel.
6677 This change dramatically decreased the complexity of channel
6678 handling with client entry and vice versa (removed one extra
6679 loop when searching for channel entry from many functions).
6681 * Changed server->sim from table to SilcDList and changed code
6684 * NAMES command can now be used from user interface. It will show
6685 the user list on the channel, neatly.
6687 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6688 Code now saves realname of the user if it becomes available.
6690 * Renamed configure.in to configure.in.pre and made ./prepare
6691 script to automatically add correct version string to
6692 configure.in which it creates from configure.in.pre.
6694 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * NAMES command reply now shows users mode with the nickname when
6699 * Moved silc_client_ch[u]mode[_char] functions from
6700 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6701 place sucks, they are utility functions and should be in some
6704 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6706 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6709 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * Added TRQ (efficient deque and list library) into lib/trq. This is
6714 a very good list library that is currently used in the SILC. Defined
6715 SilcList API over the library because I didn't like the API very
6716 much. See lib/trq/silclist.h for the API and examples of how to
6717 use the API. Fixed various places in the code to use the new
6718 SilcList API. The SilcList is meant for lists that has a structure
6719 already defined as a list. It is not suitable to add just some
6720 context to the list (in TRQ, the context is the list actually).
6722 So, I defined SilcDList that can be used for the purpose where
6723 predefined list structure does not exit. This can be used as
6724 such list. Now some context just can be added to the SilcDList.
6725 Currently this list is not used in the SILC just yet, though there
6726 are a lot places where this can replace dynamically allocated
6727 tables and I will fix these places, later, to use SilcDList.
6728 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6729 and use TRQ internally).
6731 Also fixed some annoying warning messages that the original TRQ
6732 code generated. Also minor changes to TRQ's Makefile.in.
6734 * Added support for querying by Client ID to both WHOIS and
6735 IDENTIFY commands into server, as required by the protocol.
6737 * Removed method function pointers from SilcBuffer structure. They
6738 weren't used to anything and just increased the context size for
6739 no good reason. This change also made silc_buffer_alloc and
6740 silc_buffer_free functions inline functions.
6742 * Disabled command flooding detection support until it's fixed so
6743 that it accepts commands in but does not execute them more than once
6746 * Added silc_net_localhost(), to return local hostname, into
6747 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6748 that must be initialized before calling silc_client_init.
6750 * Added new function: silc_server_send_notify_on_channels to send
6751 notify messages to all channels client has joined. It is assured
6752 that the message is sent only once per client.
6754 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6755 lib/silcutil/silcutil.[ch] as silc_format function. The new
6756 function is generic and is used by server as well, not only by
6757 the logging routines.
6759 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6760 the provided version string was not acceptable. Added new function:
6761 silc_ske_check_version into lib/silcske/silcske.h. The function
6762 must be implemented by the application (client or server) and it
6763 does not reside in the SKE library. The function checks the version
6764 string remote end sent.
6766 * Added back pointers (to opaque context and to SilcSocketConnection)
6767 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6769 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6770 duplicate packet context structure.
6772 * Changed `notify' client operation to send same arguments as client
6773 receives from server except for ID's. ID's are mapped to correct
6774 ID entry and that is returned. Also, if channel entry is not sent
6775 by server but the notify is for channel the channel entry is sent
6776 to application (otherwise application doesn't know that it is for
6777 channel (library gets it from packet's Destination ID)).
6779 * Added silc_client_remove_from_channels into client library to
6780 remove a client from all channels it has joined to. Used when
6781 received SIGNOFF notify from server. Added also new function
6782 silc_client_replace_from_channels to replace old ID entry with
6783 new ID entry on all channels. Used when received NICK_CHANGE
6786 * Fixed ID Cache list handling in silc_idlist_get_client in
6787 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6788 to get (or query) client by ID.
6790 * Updated TODO list.
6792 * Added connection authentication status message defined by the
6793 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6794 support for these into the code in client and server side.
6796 * Added generic function silc_client_send_command to send any command
6797 with variable argument list. Application should use this function
6798 to send commands if the command functions provided by the library
6799 does not suite for the application's user interface needs.
6801 * Added new `failure' client operation. Application is notified about
6802 received failure packet if client is executing a protocol. In this
6803 case the protocol's execution has failed.
6805 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6806 is required by the protocol.
6808 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6809 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6812 * Added status flag to SilcSKE object to indicate realtime status
6813 of the SKE protocol.
6815 * Application receives now exactly same command reply arguments as
6816 the library receives from server. However, if ID is received the
6817 corresponding ID entry is returned to the application (eg. Client
6818 ID is mapped to correct SilcClientEntry entry and that is returned).
6819 Changed command_reply client operation due to this change.
6821 * Changed all ID's in commands and in command replys as ID Payloads.
6822 Change affected both client and server side codes.
6824 All ID's sent in SILC network (with execption of ID's in SILC
6825 Packet header) are sent in ID Payload to support variable length
6828 * Server now notifies nick changes and notifies all clients on
6829 the channels about the new nickname (about the new Client ID,
6832 * Implemented CMODE command to change channel modes. Supports all
6833 channel modes defined by the protocol specs except ban and invite
6834 lists. (Also, private channel key mode is supported but support for
6835 setting private channel key in client is missing, thus, this mode
6836 has no effect on client side (except that server requires that the
6837 client uses private channel key and normal channel traffic does not
6840 Also, invite mode works per se, but INVITE command does not work
6841 yet correctly, so you can set channel as invite only channel but
6842 inviting clients to the channel does not work (it is yet to be
6843 thought what's the best way to do it).
6845 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6846 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6847 Implemented CUMODE command to change user's mode on the channel.
6848 Supports all modes defined by the protocol specs.
6850 * Added NAMES command reply to return users modes on the channel.
6852 * Removed unnecessary and slow ciphers from lib/silccrypt.
6854 * Set SO_KEEPALIVE option to connection sockets by default.
6856 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6858 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6859 redefined the Notify Payload into protocol specs.
6861 * Added silc_id_payload_parse_id to get ID directly from raw
6864 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6867 accept searching by Client ID as well.
6869 * Added support for LEAVE and SIGNOFF notify types in client library.
6871 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6872 to parse ID Payload from raw data.
6874 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Added flags parameter into silc_ske_assemble_security_properties
6877 function in lib/silcske/silcske.[ch].
6879 * Changed notify client operation to fit better for notify messages
6880 sent by server. The notify payload received from server is now
6881 passed to the application (after parsing it to SilcNotifyPayload).
6882 It is application's responsibility to retrieve the arguments
6883 from the payload and show the message the way it wants. The message
6884 sent by server is implementation specific.
6886 * Changed public keys to comply with the protocol specification.
6887 Old public keys are not supported anymore and are not compatible.
6889 * Removed nickname from Channel Payload as the latest draft removed
6890 it. The client must resolve the nickname from the NAMES command
6891 reply received when it joined the channel.
6893 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6895 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Fixed some errors in protocol specification drafts.
6899 * Created lib/silccore/silcnotify.c to implement Notify Payload
6900 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6901 generic payloads described by protocol specifications. The file
6902 includes implementations for ID Payload and Argument Payload.
6904 * Changed Command Payload implementation to use the new Argument
6905 Payload. Changed command_xxxx_payload to command_payload_xxxx
6906 to comply with SILC coding conventions.
6908 * Added suppport for Argument Payload handling in Notify Payload
6909 implementation as protocol requires it. Added the new support
6910 into server and client lib as well.
6912 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added support for multiple nicknames on same channel. [n] is
6915 added locally to the nickname if there are more than one same
6916 nicknames on the channel.
6918 * Server now sends all nicknames that matched WHOIS request.
6919 Client also shows the list received from server.
6921 * Added TOPIC command to client side. User can now set and show
6922 current topic on channel.
6924 * Added MOTD command to client and server. Also, server sends the
6925 motd when client connects to the server.
6927 * Changed version strings to comply ISO 8601.
6929 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Fixed protocol error handling in client library. It should now
6932 cope even if the SKE fails for some reason.
6934 * Made new protocol specification drafts for submitting to IETF.
6936 * Implemented TOPIC command to server in silcd/command.c.
6938 * Added two new notify types into lib/silccore/silcnotify.h:
6939 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6940 notify nickname change and topic setting/change on a channel.
6942 * API change of command_reply operation in client library. The
6943 application gets now the status type received from server as well.
6945 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6949 * Cras fixed and optimized the packet handling even further and
6950 it should work now. Minor change to the prototype of function
6951 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6953 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Added new function into lib/silcutil/silcschedule.[ch]:
6956 silc_schedule_with_fd to select() a specified fd. The function
6957 returns after timeout expires or data arrives or goes. The
6958 function is used by packet routines to wait that all data is
6959 received from network.
6961 * Fixed data reading from network in lib/silccore/silcpacket.c.
6962 The code now assures that all data is read from the fd and then
6963 continues packet processing. This was a bug fix since the code
6964 used to drop some data in some circumstances.
6966 * Added new function into lib/silcclient/client.[ch]:
6967 silc_client_start_key_exchange to start key exchange after
6968 connection has been established to server. The code internally
6969 now uses this funtion but its main purpose was to provide it
6970 for applications that perform their own connecting. After
6971 application has created a connection it merely calls this
6972 function to start the key exchange between client and server.
6973 The library takes care of everything else after that.
6975 Updated also lib/silcclient/README to explain the usage of
6978 * Do not send to application information that connection has
6979 been established. Application gets notified it by connect
6982 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Applied cras's patch to add silc_schedule_one function. The
6985 function runs scheduler once and returns.
6987 * Fixed the scheduler after cras messed it up. The timeout
6988 handling works now as it's supposed to work.
6990 * Added into lib/silccore/ silcnotify.h to include notify
6991 message types support. Changed silc_server_send_notify*
6992 functions, in server.[ch], to support those new notify types.
6993 Added the support for the notify types into client library,
6994 as well. Added new notify client operation into ops.h in
6997 * Changed silc_server_packet_send_to_channel to send normal
6998 packets instead of just channel message packets. The function
6999 is now used to send the notify packets to channels. It is not
7000 used to send channel message packets anymore, as server never
7003 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7004 va_arg()s as it seems to require it nowadays. I guess, if SILC
7005 is compiled with older va_arg() the new code should work anyway.
7007 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Splitted core library. Core library (lib/silccore) includes
7010 now only SILC protocol specific core (and common) components.
7011 Created new utility library (lib/silcutil) that includes more
7012 generic purpose stuff. The stuff for util library was taken
7013 from the old core library. This was minor and easy split.
7015 * Created SILC Client Library (lib/silcclient) that includes
7016 implementation of the SILC client without user interface. This
7017 was major move from silc/ directory. The code has been changed
7018 so that it is transparent towards the user interface. The
7019 silc/ directory includes now the same user interface as before
7020 and it uses the new client library. Read lib/silcclient/README.
7021 Basicly, the client library performs everything else related
7022 to SILC except user interface handling. Also, configuration
7023 files are considered to be part of user interface and library
7024 does not handle them.
7026 This change also changed a lot of structures, function naming etc.
7027 Most important change was that SilcClientWindow object was
7028 renamed to SilcClientConnection in the client library. Created
7029 also new file lib/silcclient/ops.h. Also added new files
7030 silc/local_command.[ch] and silc/client_ops.[ch].
7032 All these changes were made to make it easier for user interface
7033 designers to create what ever user interface for the SILC client
7036 It is also expected that the server will be moved to lib
7037 directory as well and SILC Server Library will be created;
7038 sometimes in the future.
7040 * Removed Local commands from lib/silccore/silccommand.h as
7041 they are application specific and new client library does not
7042 handle any of those anymore.
7044 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7045 old client implementation in silc/.
7047 * Added support for callback functions in SILC_LOG_* macros.
7048 Application can now set its own callbacks that will be called
7049 instead of using the default functions that will always print
7050 the debug messages to stderr (or stdout). Also, debugging can
7051 now be disabled by setting silc_debug to FALSE and re-enabled by
7052 setting it to TRUE. Note, that logging will still work even
7053 if debugging is disabled.
7055 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7056 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7057 silc_log_reset_debug_callbacks.
7059 * To enable debugging in silc client one must give now -d
7060 option on command line.
7062 * Changed silc_schedule_init to automatically allocate task queues
7063 if they are not allocated before calling it.
7065 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Added GMP 3.1 into math library.
7069 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7072 a channel in SILC network. The packet is used by servers and
7073 routers to notify other routers that user has left a channel.
7074 This little feature was missing until now. Added the feature
7075 to protocol specification as well.
7077 Added functions: silc_server_send_remove_channel_user and
7078 silc_server_remove_channel_user into server.[ch].
7080 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7081 lib/silccore/silcpacket.h. However, they are not implemented
7084 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7086 * Fixed joining to a channel and sending channel messages
7087 between server and router. The channel message sending should
7088 now work inside a cell.
7090 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7092 * Fixed the private message sending between server and router.
7093 The private message sending should now work inside a cell.
7095 * Added silc_server_replace_id into server.[ch] to replace
7096 existing ID in the SILC network.
7098 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7099 and silc_idlist_replace_server_id into idlist.[ch] in server.
7101 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Fixed the server to server connections. Server can again now
7104 connect to router. Router to router connections probably does
7107 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Added dynamic protocol registering support. Now protocols can
7110 registered and unregistered on the fly. Patch by cras.
7112 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added lib/contrib directory to hold routines that some platforms
7115 don't have but are needed by SILC.
7117 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7118 into lin/contrib to provide getopt() and getopt_long() for
7119 those who don't have it.
7121 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Added AWAY command to client. When away message is set and
7124 client receives a private message packet the client automatically
7125 replies to the sender with the away message.
7127 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7128 bug seemed to be the cause of recent problems when compiling
7131 * Added version detection support to SKE protocol specification
7132 and added the new changes to the SKE implementation as well.
7133 There were other minor changes in the SKE protocol as well.
7135 Many changes in lib/silcske/silcske.[ch] and in
7136 lib/silcske/payload.[ch].
7138 * Added ^U functionality, clear input line. Patch from cras.
7140 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Mainly small bugfixes on core library. Fixed some debugging
7143 logging and buffer overflow in silclog.c.
7145 * Updated config.sub and config.guess on the distribution tree.
7147 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7149 * Added command lagging support in server. Client may execute
7150 commands now only once in two seconds.
7152 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7154 * Optimized packet reception. MAC computation and checking is now
7155 also more optimized. A lot previously duplicated code is now
7156 used as generic by both client and server.
7158 * Fixed key pair generation in clientutil.c
7160 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * Added into lib/silccore/silcbufutil.[ch] new function;
7163 silc_buffer_realloc.
7165 * Moved generic packet sending/encryption functions to
7166 lib/silccore/silcpacket.[ch] from client and server. Some
7167 rewriting of the functions.
7169 * Moved all generic packet reception/decryption functions to
7170 lib/silccore/silcpacket.[ch] from client and server. The
7171 packet processing is now much cleaner in both client and server.
7172 These were major changes in both client and server.
7174 * Created many common functions in server to do packet sending.
7175 Previously code were duplicated a lot, this has been removed
7178 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Rewrote major parts of the ID cache system. Don't know
7181 whether it is better now or not but at least the API is more
7184 * Major rewrite on ID cache stuff on client because of the ID
7185 cache API changes. Added idlist.c to client.
7187 * Also major rewrite on ID cache stuff on server as well.
7188 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7189 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7190 in hand, instead they are all put into the ID cache system now.
7191 All server_idlist_* routines uses ID cache now instead of
7192 traversing its own lists (those lists does not exist anymore).
7193 SilcIDList though still exists. Also, SilcXXXEntry's are
7196 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7198 * Finally made the SKE implementation compliant to the protocol
7199 specification. All mp integers are now binary encoded as
7200 opposed being HEX encoded.
7202 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7205 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7206 functions: silc_[encode/decode]_pem. Also added function
7207 silc_encode_pem_file to PEM encode with newlines ('\n') for
7210 * SILC public keys are now encoded either PEM or binary. Same
7211 option is for private keys as well. By default private keys
7212 are binary encoded and public keys PEM encoded. Silly HEX
7213 encoding were removed.
7215 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7216 function to create fingerprints.
7218 * Fixed a bug in SHA1; does not change the original data anymore.
7220 * Partly implemented INFO command on client and server side.
7221 Fixed CLEAR command. Changes to SERVER command; show current
7222 server(s) when giving command without arguments. Added
7223 VERSION command to client.
7225 * Added check to server that unregistered connections cannot
7226 execute commands (unless it is specificly allowed).
7228 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Fixed screen refresh.
7232 * Fixed channel joining bug from client. On some circumstances
7233 client tried to join to a channel it had already joined.
7235 * Added public key verification process into client's protocol.c.
7236 The client now verifies the public key from user and saves
7237 it into ~./silc/serverkeys/ directory.
7239 Added into: clientutil.[ch]: silc_client_verify_server_key.
7241 * Changed SKE protocol's silc_ske_initiator_finish function
7242 to accept callback function that verifies the received public
7243 key. Removed old silc_ske_verify_public_key function.
7245 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7247 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7248 silc_pkcs_private_key[_data]_set.
7250 * Made the password and public authentication more cleaner in
7251 server's protocol.c.
7253 * Removed historic and obsolete protocol `channel_auth' from
7254 both client and server.
7256 * Removed wrong way of sending command status messages from
7257 server to client in server's command.c. The old way violated
7258 protocol specification.
7260 Changes to silccore/silccommand.[ch]: removed
7261 silc_command_encode_status_payload -> not needed anymore,
7262 changed silc_command_encode_payload_va to accept extra
7263 argument on variable argument list. The argument type must
7264 now be provided to the function. Also, added new function:
7265 silc_command_encode_reply_payload_va which is same as
7266 normal command_encode_payload_va except command status type
7267 is provided as extra argument.
7269 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7271 * Added ~./silc directory handling. The directory includes the
7272 public and private keys for the client.
7274 Added silc_client_check_silc_dir, silc_client_create_identifier
7275 and silc_client_load_keys.
7277 * Implemented SILC protocol compliant public key. Added public
7278 and private key saving to and loading from files.
7280 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7281 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7282 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7283 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7284 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7286 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7287 silc_pkcs_load_[public/private]_key.
7289 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * Added silc_server_get_route (route.[ch]) to get connection
7292 data for the fastest route for given ID.
7294 * Implemented INVITE command on client and server. The command
7295 were re-defined in the SILC Protocol Specification and the
7296 implementation now complies with the specification.
7298 * Implemented PING command on client and server.
7300 * Implemented NAMES command on client and server. The server side
7301 supports currently only normal server not router server yet.
7302 Some changes to NAMES definition in SILC protocol specification.
7304 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7306 * Implemented LEAVE command on client and server.
7308 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7309 again. This change was made to the protocol as well. Server
7310 should not violate the protocol specification anymore.
7312 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7315 was tested. SOCKS4 was not but should work anyway.
