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

235 algorithm parts and created new file silcalgs.conf, that
236 is now included from the example_silcd.conf.in.
238 * Optimized the silc_server_connect_to_router_second to take
239 the connection configuration object from the SilcServerConnection
240 object instead of finding it during the connecting phase.
241 Added the configuration object to SilcServerConnection struct.

270 public key is set. If not set, public key is preferred.
271 This has effect only when being initiator (responder will try
274 Added support for authentication with passphrase and public key
275 at the same time. The passphrase is tried first always since
276 it is faster to check.
278 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].

326 * Fixed the file transfer's key agreement payload to include
327 zero port also if the hostname is NULL because it could not
330 Call file transfer monitor callback now also if error occurs
331 during key agreement protocol.
333 Changed the silc_client_file_send interface to return the
334 SilcClientFileError instead of session id. The session ID
335 is returned into pointer provided as argument.

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

375 become invalid in the callback but it was referenced after
376 the callback returned.
378 Do not allow auto rehashing of hash table during the
379 silc_hash_table_foreach operation, for same reasons as it is
380 not allowed for SilcHashTableList. Affected files are
381 lib/silcutil/silchashtable.[ch].

409 rehashed. It is now guaranteed that auto rehashable tables
410 are not rehashed while tarversing the list. Also defined that
411 silc_hash_table_rehash must not be called while tarversing
412 the table. Added function silc_hash_table_list_reset that must
413 be called after the tarversing is over. The affected files are
414 lib/silcutil/silchashtable.[ch].
416 * Changed all hash table traversing to call the new
417 silc_hash_table_list_reset in server and in client library.
419 * Added function silc_client_on_channel to return the

436 sender's old command identifier was not saved back to the
437 sender's command context, fixed now. The affected file is
440 * Create the key in JOIN command of the router did not return
441 the channel key, added check for this. Affected file is
444 * Fixed a channel ID update bug in JOIN command reply. Do
445 not directly upgrade the ID but call the function
446 silc_idlist_replace_channel_id if the ID was changed.
447 Affected file silcd/command_reply.c.
449 * Fixed memory leaks from command calling if it would fail.
450 Affected file silcd/command.c.

557 lib/silcclient/command.c.
559 * Added silc_client_start_key_exchange_cb and lookup the
560 remote hostname and IP address before starting the key
561 exchange with server. The affected file is
562 lib/silcclient/client.c.
564 * The server's public key is now saved using the IP address
565 of the server and not the servername for the filename.
566 The hostname public key filename is checked as an fall back
567 method if the IP address based filename is not found.
569 Fixed the GETKEY command to save the fetched server key
572 Print the remote server's hostname now when new key is
573 received during connection process. Affected file is
574 irssi/src/silc/core/client_ops.c.
576 * Return always our own public key to the client if it asks
577 for it with GETKEY command. Affected file silcd/command.c.
579 * Removed the use_auto_addr variable from default config
580 file since it was in wrong section. Affected file is
583 * Fixed TOPIC_CHANGE notification to not route it when it
584 was sent using silc_server_send_notify_to_channel function.
585 Affected file silcd/command.c.
587 * Fixed silc_server_send_notify_kicked to send the kicker's
588 Client ID also, it was missing. Affected files are
589 silcd/command.c, silcd/packet_send.[ch].
591 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
593 * Do not save client history information in SERVER_SIGNOFF.
594 Fixes the bug in normal server that it does not detect
595 the client becoming valid after the server becomes back
596 online. Affected file silcd/server_util.c.
598 * Added `sock_error' field into the SilcSocketConnection
599 context. When error occurs during socket operation (read
600 or write) the error is saved. Added also new function
601 silc_socket_get_error to return human readable socket error
602 message. Affected files are lib/silcutil/silcsockconn.[ch],
603 lib/silcutil/unix/silcunixsockconn.c, and
604 lib/silcutil/win32/silcwin32sockconn.c.
606 * The server now prints the socket error message in the
607 signoff for client. Affected file silcd/server.c.
609 * Fixed the `created' channel information sending from router
610 to server in JOIN command. Checks now whether the channel
611 really was created or not and set it according that.
613 Fixed the JOIN command to use the client entry's current
614 ID during the joining procedure instead of the one it sent
615 in the command (it is checked though), since it can change
616 between the packet processing and command processing, and
617 would just case unnecessary pain in the client end. Affected
618 file silcd/command.c.
620 * Fixed a channel key payload sending to use correct channel
621 ID when the server was forced to change the channel's ID by
622 router. Router sent the key payload with the old Channel ID.
623 Affected file silcd/packet_receive.c.
625 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
627 * Call silc_server_save_channel_key only if the key payload
628 was provided in the JOIN command's command reply. Affected
629 file silcd/command_reply.c.
631 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed silc_mp_sizeinbase to return the value correctly with
634 MPI. Affected file lib/silcmath/mp_mpi.c.
636 * Fixed the stop_server signal to correctly stop the scheduler
637 and gracefully stop the server when SIGTERM or SIGINT signals
638 are received. Affected file silcd/silcd.c.
640 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
642 * Simple handling of TERM and HUP signals. Also added some log
643 flushing call around. Affected file is
646 * Fixed small bugs in silclog.c. Now buffering output will take
647 effect after 10 seconds since startup: This will ensure that
648 no important startup messages are lost. Also output redirection
649 will preserve original format ([Date] [Type] message).
650 Affected file is lib/silcutil/silclog.c.
652 * Added two options to the config file, in the logging section:
653 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
654 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
656 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
658 * Do not print the warning about log files not being initialized
659 more than once to avoid excess logging. Affected file is
660 lib/silcutil/silclog.c.
662 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
663 the SIM copying in make install in Makefile.am.pre.
665 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
667 * Rewritten silclog APIs. Globally interesting changes follows:
668 silc_log_set_files() changed to silc_log_set_file().
669 silc_log_set_callbacks() changed to silc_log_set_callback().
670 ROBOdoc documented silclog header file.
671 SilcLogCb now returns bool to wether inihibit the default
672 handler or not (to keep the old behaviour return always TRUE).
673 The new APIs should also fix the problem of the
674 silcd_error.log file that was written in the current directory.
677 Log files streams will remain opened after silc_log_set_file()
678 call, means less CPU usage notably on high traffic servers.
679 File streams are now full buffered, and flushed to the disk
680 every 5 minutes, lesses HD activity and CPU usage.
681 Messages can be redirected, allowing admins to configure
682 one single logfile for all server messages.
683 the silc_log_quick global variable to activate fast-logging.
684 Affected files lib/silcutil/silclog.[ch]
686 * Changed some code to conform new silclog APIs. Affected
687 files are doc/example_silcd.conf.in, silcd/server.c
688 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
691 * Fixed a memory leak that could occur in some situations.
692 Affected file silcd/serverconfig.c.
694 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
696 * Added the silc_client_del_client to remove the client from
697 all channels as well. Affected file lib/silcclient/idlist.c.
699 * Fixed the client library to correctly remove the client
700 from all channels when the client entry is being destroyed.
701 Affected file lib/silcclient/client_notify.c, command.c.
703 * Added auto-nicking support to the client library. If the
704 applicatio now sets client->nickname it will be sent to the
705 server after connecting by the library. This way for example
706 SILCNICK (or IRCNICK) environment variables will have effect
707 and always change the nickname automatically to whatever
708 it is wanted. Affected file lib/silcclient/client.[ch].
710 * Renamed silc_server_command_bad_chars to the
711 silc_server_name_bad_chars and moved it to the
712 silcd/server_util.[ch]. Added also new function
713 silc_server_name_modify_bad to return nickname that
714 includes bad characters as new nickname without those
715 bad characters. This check and modify is now used in
716 silc_server_new_client when the username is initially set
717 as nickname, so it must be checked to be valid nickname.
718 Affected file silcd/packet_receive.c.
720 * The nickname length is now taken from the packet for real
721 and not trusted to strlen() since it clearly can return
722 wrong length for nickname including bad characters. This
723 also applies to channel names. Affected file silcd/command.c.
725 * Removed the lib/silcsilm/modules directory. Modules are now
726 compiled into the lib/silcsim. Fixed the copying of the
727 modules to follow symbolic links in Makefile.am.pre.
729 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
731 * Fixed silc_string_regexify list creation. Fixes bugs with
732 BAN and INVITE commands in server. The affected file is
733 lib/silcutil/unix/silcunixutil.c.
735 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Removed the command destructor entirely from the server's
738 command and command reply routines. It is not needed, and
739 its usage was buggy and caused crashes. Affected files are
740 silcd/command[_reply].[ch].
742 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
744 * Cancel protocol and NULL sock->protocol if timeout
745 occurred during protocol. Affected file silcd/server.c.
747 * Cancel protocol timeouts always before calling the final
748 callback, to assure that after final callback is called
749 no other state will be called for the protocol anymore.
750 Affected file silcd/protocol.c.
752 * Print error log if incoming connection configuration could
753 not be found. Affected file silcd/server.c.
755 * Fixed JOIN command to correctly save the founder mode
756 to the client on normal SILC server, when the channel
757 was created by the router. Affected file silcd/command.c.
759 * Fixed LIST command (hopefully) to send correct reply
760 packets. Affected file silcd/command.c.
762 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
764 * The silc_packet_receive_process now returns FALSE if the
765 read data was invalid packet, and TRUE if it was ok.
767 The server now checks that if unauthenticated connection
768 sends data and its processing fails the server will close
769 the connection since it could be a malicious flooder.
771 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
773 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
775 * Make sure the warning about error opening a log file is
776 printed only once and not everytime it fails (produces
777 too much useless log). Affected file lib/silcutil/silclog.c.
779 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
781 * Made the silc_server_daemonise() function more readable.
782 Affected file silcd/server.c.
784 * Pid file is now optional, the user may comment it out from
785 the config file. Removed define SILC_SERVER_PID_FILE, we
786 don't need a default any longer. Affected file
787 configure.in.pre, lib/Makefile.am.pre.
789 * Make some use of the pid file. The server now dies at startup
790 if it detects a valid pid file on his path. The server would
791 die anyway in this circumstance, because of the bind() failure.
792 Affected file silcd/silcd.c.
794 * No longer compiling lib/dotconf.
796 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Fixed JOIN command parsing not to crash. Affected file
799 lib/silcclient/command.c.
801 * Fied the NICK_CHANGE notify to add the new client entry
802 even it is resolved. This removes an <[unknown]> nick
803 thingy bug in the client. Affected file is
804 lib/silcclient/client_notify.c.
806 * Do not try to allocate 0 bytes (efence does not like it)
807 in lib/silccore/silccomand.c when encoding payload.
809 * Do not take IRCNICK as nickname in Irssi SILC client since
810 it is not possible to set nickname before hand connecting
811 the server (TODO has an entry about adding auto-nicking
814 * Changed the silc_server_command_pending to check whether
815 there already exists an pending entry with the specified
816 command, command identifier and pending callback. This is
817 to fix IDENTIFY and WHOIS related crashes that may register
818 multiple pending commands with same identifier. Affected
819 file silcd/command.c.
821 * Fixed the server to reconnect to the router even if it
822 was already reconnecting and EOF was received. This to
823 fix a possibility that the server wouldn't ever try to
824 auto-reconnect to the router. Affected file silcd/server.c.
826 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Fixed the server's password authentication to use the
829 length of the locally saved password, and not the one
830 sent in the packet. Affected file silcd/protocol.c.
832 * Fixed same password authentication problem in the
833 Authentication Payload handling routines in
834 lib/silccore/silcauth.c.
836 * Yet another password authentication problem fixed with
837 channel password handling in silcd/command.c.
839 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
841 * If first character of string in silc_parse_userfqdn is '@'
842 then do not parse it. Affected file is
843 lib/silcutil/silcutil.c.
845 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
847 * Fixed minor bug in IDENTIFY command reply sending, which
848 caused various weird problems during JOIN when it was
849 resolving names for users. Affected file silcd/command.c.
851 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Fixed the IDENTIFY command reply sending to chech better valid
854 clients. It was possible to send incomplete list of replies.
855 Affected file silcd/command.c.
857 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Added silc_client_command[s]_[un]register functions now to
860 dynamically register the commands in client library. Removed
861 the static table of commands. This allows the client library
862 to call commands without causing the application to know about
863 what commands library has called.
865 Removed the INFO command reply kludge to detect when the command
866 was called by library. Now library use its own command reply
867 function for INFO command.
869 Added function silc_client_command_call to call a command.
870 Application can use it to call command, not access the structure
873 Now all commands that are sent by the client library (not
874 explicitly sent by application) use own command reply functions.
876 Affected files around lib/silcclient/ and in
877 irssi/src/silc/core/.
879 * Fixed the WHOIS command reply sending to chech better valid
880 clients. It was possible to send incomplete list of replies.
882 Fixed the WHOIS and IDENTIFY to send the request to router
883 if normal server did not do it and did not find any results.
885 Affected file silcd/command.c.
887 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Moved the internal data from SilcClient context into its
890 own file, not accesible to application. Affected files
891 lib/silcclient/client.h and lib/silcclient/client_internal.h,
892 and other files in client library.
894 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
896 * Added doc/examples installation target in Makefile.am.pre.
899 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
902 commands the found client entry will be removed from the
903 cache, after notifying application about the error. Affected
904 file lib/silcclient/command_reply.c.
906 * Changed the /MSG to check for exact nickname user gave, and
907 not let `nick' match `nick@host' if it is only one found. Now,
908 user must type the exact nickname (like nick@host2) even if
909 there are no more than one same nicks found. This is to avoid
910 a possibility of sending nickname to wrong nickname since
911 `nick' could match `nick@host'. Affected file is
912 irssi/src/core/silc-servers.c.
914 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
916 * Do not print "you are now server operator" or similar when
917 giving /away command. Affected files are
918 irssi/src/silc/core/client_ops.c, silc-servers.h.
920 * Made the silc_server_command_pending_error_check to send
921 the same command reply payload it received back to the
922 original sender of the command. This way all arguments
923 that was received by the server will be received by the
924 client too. Affected file silcd/command.c.
926 * Added the silc_idcache_add to return the created cache entry
927 to a pointer. Affected file lib/silccore/silcidcache.[ch].
929 * Add global clients to expire if they are not on any channel.
930 This is because normal server will never know if they signoff
931 if they are not on any channel. The cache expiry will take
932 case of these entries. This is done by normal servers only.
933 The affected files are silcd/command_reply.c,
934 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
936 * If server receives invalid ID notification for WHOIS or
937 IDENTIFY and the ID exists in the lists, it is removed.
938 Affected file silcd/command_reply.c.
940 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
941 in client then client entry that it matches is searched and
942 the nickname is printed on the screen for user. Affected
943 file irssi/src/silc/core/client_ops.c.
945 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
947 * Use cache entry expire time in the LIST command reply to
948 purge old entries from the cache after the LIST command
949 reply has been received. This way we don't have non-existent
950 entries in the cache for too long. Affected file is
951 silcd/command_reply.c.
953 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
955 * If we are normal server, and we've not resolved client info
956 in WHOIS or IDENTIFY from router, and it is global client,
957 we'll check whether it is on some channel. If it is not
958 then we cannot be sure about its validity and will resolve it
959 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
960 file silcd/command.c.
962 * Search channel by name (if possible) rather than by ID
963 in IDENTIFY command's command reply. Affected file is
964 silcd/command_reply.c.
966 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
968 * Distribute to the channel passphrase in CMODE_CHANGE notify.
969 Updated specs and implemented it. Affected file silcd/command.c,
970 silcd/packet_send.c and silcd/packet_receive.c.
972 * Implemented the <founder auth> payload handling in the JOIN
973 command. If provided all conditions for channel joining
974 except requirement to provide correct passphrase can be
975 overrided by the channel founder. Updated the protocol specs.
976 Affected file silcd/command.c.
978 Added support for founder auth in JOIN command in client
979 library. Fixed the parsing of the JOIN command now to support
980 all options as they should be. The affected file is
981 lib/silcclient/command.c.
983 * Optimized the WHOIS and IDENTIFY commands to send the request
984 to router only if it includes nicknames or other names. If
985 they include only IDs then check the local cache first before
986 routing. Affected file is silcd/command.c.
988 * Added channels topic announcements. Affected file is
989 silcd/packet_receive.c and silcd/server.c.
991 * Fixed the silc_server_send_notify_topic_set to really destine
992 the packet to channel. Affected file silcd/packet_send.c.
994 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
995 library. Affected file lib/silcclient/client_notify.c.
997 * Added UMODE announcements. Affected file silcd/server.c.
999 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Memory leak fixes in:
1003 lib/silcutil/silcsockconn.c
1004 lib/silcske/silcske.c
1005 lib/silcske/groups.c
1007 lib/silccrypt/silcpkcs.c
1008 lib/silccore/silccommand.c
1009 lib/silccore/silcidcache.c
1014 * ROBOdoc documented the lib/silcske/groups.h file and a
1015 bit changed the interface for better.
1017 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1019 * Update the client entry context in the ID cache after
1020 nick change. Affected file lib/silcclient/command.c.
1021 Fixes the CUMODE command when regaining founder privileges,
1022 and a little WHOIS problem.
1024 * Fixed silc_net_gethostbyname to correctly call the
1025 inet_ntop. Affected file lib/silcutil/silcnet.c.
1027 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1029 * Added IPv6 support checking to the configure.in.pre, added
1030 also --enable-ipv6 option to override the check. Affected
1031 file configure.in.pre.
1033 * The silc_thread_create now calls the start function
1034 directly if threads support is not compiled in. Removes
1035 ugly #ifdef's from generic code. Affected files are
1036 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1038 * Added silc_net_gethostby[name/addr]_async to asynchronously
1039 resolve. Affected files are lib/silcutil/silcnet.[ch].
1041 * Added support for rendering IPv6 based server, client and
1042 channel IDs. Affected file lib/silcutil/silcutil.c.
1044 * Added support for creating IPv6 based server IDs. Affected
1045 file is silcd/serverid.c.
1047 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1049 * Added silc_net_gethostby[addr/name] into the
1050 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1051 routines. Added silc_net_is_ip[4/6]. Affected file is
1052 lib/silcutil/unix/silcunixnet.c. All routines that take
1053 address as argument now supports both IPv4 and IPv6 addresses.
1055 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1057 * Fixed LIST command reply sending in server. Affected file
1060 * Server now sends the kicker's client ID in the KICK notify
1061 to the kicked client. Affected file silcd/command.c.
1063 * The client library now parses the kickers client ID and
1064 UI displays it. Affected files lib/silcclient/client_notify.c
1065 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1067 * Made all payload parsing function prototypes consistent.
1068 They all take now const unsigned char * and uint32 pair as
1069 the payload data instead of SilcBuffer. Changes all around
1070 the source tree. Other unsigned char* -> const unsigned char*
1071 changes around the tree as well.
1073 * Optimized SFTP client and server packet sending not to
1074 allocate new buffer for each packet but to recycle the
1075 first allocated buffer. Affected files are
1076 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1078 * Optimized the SFTP client to use SilcList instead of
1079 SilcDList for requests, because it is faster. Affected file
1080 is lib/silcsftp/sftp_client.c.
1082 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1083 into lib/silccore/silcid.[ch].
1085 Renamed silcpayload.[ch] into silcargument.[ch].
1087 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * If client entry is deleted with active key agreement
1090 session, abort the session.
1092 The silc_client_abort_key_agreement now calls the completion
1093 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1095 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1098 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Don't use __restrict in older GCC's. Affected file is
1101 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1103 * silc_net_localhost now attempts to reverse lookup the
1104 IP/hostname. Affected file lib/silcutil/silcnet.c.
1106 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1107 command. It can be used to gain founder privileges at
1108 the same time when joining the channel.
1110 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1111 kicker's client ID as well. Updated protocol specs.
1113 Defined that the server must send SILC_COMMAND_IDENTIFY
1114 command reply with error status to client who sent
1115 private message with invalid client ID.
1117 Updated the protocol specification.
1119 * Added silc_server_send_command_reply to send any
1120 command reply. Affected file silcd/packet_send.[ch].
1122 * Added silc_id_payload_encode_data to encode ID payload
1123 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1125 * The server now send IDENTIFY command reply with error
1126 status if client ID in private message is invalid. Affected
1127 file silcd/packet_receive.c.
1129 * Save the server key file with server's IP address in
1130 the filename instead of hostname. The affected file is
1131 irssi/src/silc/core/client_ops.c.
1133 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1135 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1138 * Added libtool support for compiling shared objects in
1139 lib/silcsim. Affected file configure.in.pre and
1140 lib/silcsim/Makefile.am. Original patch by cras.
1142 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1144 * Pid file configuration, and server's config file fixes
1145 patch by toma. Updated CREDITS file.
1147 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Fixed silc_client_channel_message to not try to decrypt
1150 the message twice if it resolved the destination client
1151 information. This could cause of dropping one channel
1152 message. Affected file lib/silcclient/client_channel.c.
1154 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1156 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1157 lib/silcclient/client.c. This function is used when the SILC
1158 Client is run under some other scheduler, or event loop or
1159 main loop. On GUI applications, for example this may be
1160 desired to used to run the client under the GUI application's
1161 main loop. Typically the GUI application would register an
1162 idle task that calls this function multiple times in a second
1163 to quickly process the SILC specific data.
1165 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1167 * Fixed silc_server_drop() for dropping the supplementary
1168 groups as well, this could cause a security hole on some
1171 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1173 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1176 * Write PID file after dropping privileges. Added -F option
1177 to run server on foreground. A patch by debolaz.
1178 Affected files silcd/server.c, silcd/silcd.c.
1180 * Fixed MOTD to return the MOTD file server name. Affected
1181 file silcd/command.c.
1183 * Added INFO command reply handling to the Irssi SILC Client.
1184 Affected file irssi/src/silc/core/client_ops.c.
1186 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Fixed the silc_idcache_list_* routines to really support
1189 the dynamic list. Fixes a crash. Affected file is
1190 lib/silccore/silcidcache.c.
1192 * Fixed the LIST command reply to really call LIST command's
1193 pending callbacks. Affected file silcd/command_reply.c.
1195 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Update conn->local_entry->nickname after giving NICK
1198 command. Affected file lib/silcclient/command.c.
1200 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1202 * Added the [pid] option to the silcd configuration file
1204 Affected files: serverconfig.[ch] and silcd.c
1206 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Save fingerprint in WHOIS command reply in server.
1209 Affected file silcd/command_reply.c.
1211 * Fixed NICK commands pending callback registration.
1212 Affected file lib/silcclient/command.c.
1214 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1216 * Use ++server->cmd_ident when sending commands in server,
1217 instead of random number. Affected file silcd/command.c.
1219 * Fixed GETKEY command reply to call actually GETKEY pending
1220 command callbacks. Affected file silcd/command_reply.c.
1222 * A bit stricter check for nicknames. Check for same nickname
1223 in NICK command also. Affected file silcd/command.c.
1225 * Do not call INFO command everytime client ID changes, only
1226 during first connecting. Affected file lib/silcclient/client.c.
1228 * Set the new nickname only after successful command reply for
1229 NICK command is returned by server. Affected file
1230 lib/silcclient/command.c.
1232 * Remove nicknames from nicklist during server_signoff notify.
1233 Should fix /NAMES bit more. The affected file is
1234 irssi/src/silc/core/silc-channels.c.
1236 * Added `fingerprint' field to the SilcIDListData in the
1237 silcd/idlist.h to hold the fingerprint of the client's
1240 Send the fingerprint of the client's public key in WHOIS
1243 Affected files silcd/command.c, and silcd/idlist.[ch].
1245 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1246 create fingerprint from given data.
1248 * Show the fingerprint of the client's public key in WHOIS.
1249 Affected files irssi/src/module-formats.[ch] and
1250 irssi/src/silc/core/client_ops.c.
1252 * Format the multiple same nicknames also during JOIN and
1253 NICK_CHANGE notifys. Affected file is
1254 lib/silcclient/client_notify.c.
1256 * Do not print error on screen for invalid private message
1257 payload since it can come if someone is sending private
1258 messages with wrong key. Affected file
1259 lib/silccore/silcprivate.c.
1261 * Fixed multiple concurrent /PING crash. Affected file
1262 lib/silcclient/command.c.
1264 * Changed the wrong ID encoding. All IP addresses must be
1265 in MSB first order in encoded format. They were encoded
1266 wrong and was in LSB format. Affected files are
1267 silcd/serverid.c, lib/silcutil/silcutil.c.
1269 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1271 * Call the `connect' client operation through the scheduler
1272 in case of error. Affected file lib/silcclient/client.c.
1274 * Call the `failure' client operation even if the error
1275 occurred locally during a protocol. Affected file is
1276 lib/silcclient/protocol.c.
1278 * Added support of sending LIST command to router from normal
1279 server. This way normal server can get list of all channels
1280 in the network too. Fixed the channel list sending in the
1281 server too. Affected files are silcd/command.c, and
1282 silcd/command_reply.[ch].
1284 * Added silc_server_update_channels_by_server and
1285 silc_server_remove_channels_by_server. They are used during
1286 disconnection of primary router and in backup router protocol.
1287 Affected file silcd/server_util.[ch], silcd/server.c and
1288 silcd/server_backup.c.
1290 * Fixed channel adding to global list in IDENTIFY command
1291 reply in server. Affected file silcd/command_reply.c.
1293 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * If the incoming packet type is REKEY or REKEY_DONE process
1296 that packet always synchronously. Fixes yet another MAC
1297 failed error on slow (dialup) connections. Affected file
1298 lib/silcclient/client.c and silcd/server.c.
1300 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Call check_version SKE callback for initiator too. Affected
1303 file lib/silcske/silcske.c.
1305 * Implemented fix for security hole found in the SKE that was
1306 fixed in the specification few days back; the initiator's
1307 public key is now added to the HASH value computation.
1308 Added backwards support for the old way of doing it too, for
1309 old clients and old servers. Affected file is
1310 lib/silcske/silcske.c.
1312 * Enabled mutual authentication by default in SKE. If initiator
1313 is not providing mutual authentication the responder will
1314 force it. This will provide the proof of posession of the
1315 private key for responder. The affected files are
1316 lib/silcclient/protocol.c and silcd/protocol.c.
1318 * Do not cache anymore the server's public key during SKE.
1319 We do mutual authentication so the proof of posession of
1320 private key is done, and if the server is authenticated in
1321 conn auth protocol with public key we must have the public
1322 key already. Affected file silcd/protocol.c.
1324 * Added new global debug variable: silc_debug_hexdump. If
1325 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1326 file lib/silcutil/silclog.[ch].
1328 * Fixed compilation warning due to char * -> const char *.
1329 Affected files lib/silcutil/silcnet.h, and
1330 lib/silccore/silcauth.[ch].
1332 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1334 * Fixed CMODE command when new channel key was created. If
1335 the creation failed the old key was removed. Next time giving
1336 same command would crash the server since the old key was
1337 freed already. Affected file silcd/command.c.
1339 * Fixed the silc_server_announce_get_channels to not crash
1340 on reconnect. Affected file silcd/server.c.
1342 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Added silc_log_set_debug_string function to set a regex
1345 string to match for debug output. Only the function names,
1346 or filenames matching the given debug string is actually
1347 printed. This way it is possible to filter out those debug
1348 strings that user is not interested in.
1350 Fixed a bug in silc_string_regexify.
1352 Affected files lib/silcutil/silclog.[ch], and
1353 lib/silcutil/unix/silcunixutil.c.
1355 * Changed the -d options in both server and Irssi SILC client
1356 to take the debug string as argument. Affected files
1357 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1359 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1361 * Added silc_hash_babbleprint to create a Bubble Babble
1362 Encoded fingerprint. The encoding is developed by Antti
1363 Huima (draft-huima-babble-01.txt), and it creates human
1364 readable strings out of binary data. Affected file
1365 lib/silccrypt/silchash.[ch].
1367 * Print the babble print now in addition of fingerprint as well
1368 in Irssi SILC client. Affected files are
1369 irssi/src/fe-common/silc/module-formats.[ch],
1370 irssi/src/fe-common/silc/core/client_ops.c.
1372 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Fixed a security problem found in SKE. The initiator's
1375 public key too is now added to the HASH hash value creation
1376 which is signed by the responder to create the SIGN value.
1377 This will prevent anyone in the middle to lie to the responder
1378 about the initiator's public key. If this is done now, the
1379 man in the middle will get caught. Updated the protocol
1382 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Better installation directory handling. Configure module
1385 paths and other paths automatically to example_silc* files
1386 in doc/. A patch by toma.
1388 * Fixed compiler warning from MPI library, and from SILC RNG.
1391 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1392 It can be configured with ./configure. A patch by toma.
1394 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Find correct make to use in prepare-clean. A patch by
1397 toma. Affected file prepare-clean.
1399 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1401 * Added irssi variables use_auto_addr, auto_bind_ip,
1402 auto_bind_port and auto_public_ip.
1404 * Changed the interface for silc_client_send_key_agreement
1405 in lib/silcclient/silcapi.h
1409 irssi/src/silc/core/silc-core.c
1411 lib/silcclient/silcapi.h
1412 irssi/src/silc/core/silc-channels.c
1413 lib/silcclient/client_keyagr.c
1416 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Added silc_pkcs_public_key_compare to compare two
1419 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1421 * Check that the client who set the founder mode on the
1422 channel is the same client that is giving the founder
1423 mode to itself. It is done by comparing the saved public
1424 key (it is saved even in the authentication is passphrase).
1425 Affected file silcd/command.c.
1427 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Do not process packet for disconnected socket connection.
1430 Affected file lib/silccore/silcpacket.c.
1432 * Process the DISCONNECT packet through scheduler in the
1433 client library. Affected file lib/silcclient/client.c.
1435 * Fixed the silc_client_packet_parse to not to increase
1436 the packet sequence number if the conn->sock and the
1437 current socket connection is not same. This can happen
1438 for example during key agreement when the conn includes
1439 multiple socket connections (listeners). Affected file
1440 lib/silcclient/client.c.
1442 * The sender of the file transfer request now provides also
1443 the pointer (listener) for the key exchange protocol. If
1444 the listener cannot be created then it sends empty key
1445 agreement and lets the receiver provide the listener.
1447 Added `local_ip' and `local_port' arguments to the
1448 silc_client_file_send. If they are provided they are used,
1449 if not then it will attempt to find local IP address, if
1450 not found or bind fails then the remote client will provide
1453 Affected files are lib/silcclient/client_ftp.c and
1454 lib/silcclient/silcapi.h.
1456 * Extended the FILE SEND command to support defining the
1457 local IP and port for key exchange listener. They are
1458 optional. Affected file irssi/src/silc/core/silc-servers.c.
1460 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Defined to WHOIS command reply the sending of fingerprint
1463 of the client's public key (if the proof of posession of the
1464 corresponding private key is verified by the server).
1465 Updated to the protocol specification.
1467 * Added support of receiving the client's public key's
1468 fingerprint in command reply in client library. Affected
1469 file is lib/silcclient/command_reply.c, and
1470 lib/silcclient/idlist.[ch].
1472 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Do not send over 128 chars long nickname to the server
1475 in NICK command. Affected file lib/silcclient/command.c.
1477 * Do not send over 256 chars long channel names to the server
1478 in JOIN command. Affected file lib/silcclient/command.c.
1480 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Assure that silc_server_close_connection cannot be called
1483 twice for same socket context. Affected file is
1486 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Send error message to application if opening file for
1489 writing during file transfer fails. Affected file is
1490 lib/silcclient/client_ftp.c.
1492 Remove all file transfer sessions for a client that we're
1493 removing from ID cache.
1495 Affected file is lib/silcclient/client_ftp.c.
1497 * Fixed silc_net_addr2bin to return correct address. Affected
1498 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1500 * Fixed file transfer session removing on signoff notify.
1501 Affected file irssi/src/silc/core/silc-servers.c.
1503 * Added the SilcClientFileError to be returned in the monitor
1504 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1505 Affected file lib/silcclient/silcapi.h.
1507 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Fixed a crash in silc_client_ftp_free_sessions and
1510 silc_client_ftp_session_free_client. Affected file
1511 lib/silcclient/client_ftp.c.
1513 * Added `disabled' field in the SilcChannelEntry in the server
1514 to indicate if the server entry is disabled. Affected file
1515 silcd/idlist.h, silcd/command[_reply].c.
1517 * SILC server adds now /var/run/silcd.pid everytime it is
1518 started. Affected file silcd/silcd.c.
1520 * Added silc_server_packet_send_clients to send a packet to
1521 the provided table of client entries. Affected file
1522 silcd/packet_send.[ch].
1524 * Fixed a crash in client resolving in client_prvmsg.c in
1525 client library. Affected file lib/silcclient/client_prvmsg.c.
1527 * Do not actually remove the client directly from ID cache
1528 during SERVER_SIGNOFF, but invalidate it. This way we
1529 preserve the WHOWAS info for the client. Affected file
1530 silcd/server_util.c.
1532 * Fixed SERVER_SIGNOFF notify handling in the server. The
1533 server is now able to process incoming SERVER_SIGNOFF notify
1534 for a server that it doesn't even know about. It will remove
1535 the clients provided in the notify. Affected file
1536 silcd/packet_receive.c.
1538 * Check for partial packet in data queue after every packet that
1539 was found from the queue. Return and wait for more data if
1540 there is partial data in queue. Affected file is
1541 lib/silccore/silcpacket.c.
1543 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Added SilcClietFileError enum to indicate error in
1546 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1547 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1548 Affected files lib/silcclient/silcapi.h and
1549 lib/silcclient/client_ftp.c.
1551 * Check that newsize in silc_buffer_realloc is larger than
1552 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1554 * Added better monitor of file transfers. It now monitors
1555 key agreement protocol during the file transfer too. Added
1556 error reporting too. Affected files
1557 irssi/src/silc/core/silc-servers.c,
1558 irssi/src/fe-common/silc/module-formats.[ch].
1560 * Wrote a help file for FILE command.
1562 * Added silc_rng_global_get_byte_fast to get not-so-secure
1563 random data as fast as possible. Random data is read from
1564 /dev/urandom if available and from the SILC RNG if not
1565 available. It is used in padding generation. Affected file
1566 lib/silccrypt/silcrng.[ch].
1568 * All packets in client library are now processed synchronously.
1569 Optimized packet processing a lot. Affected file
1570 lib/silcclient/client.c.
1572 * All server connection packets are processing synchronously
1573 now in server, to optimize packet processing. Affected file
1576 * Include files are installed now only in Toolkit distribution
1577 if make install is given. Affected files: all Makefile.am's.
1579 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Assure that silc_client_notify_by_server_resolve does not
1582 resolve the client information multiple times. If it cannot
1583 be found by the first it cannot be found at all. Affected
1584 file lib/silcclient/client_notify.c.
1586 * Fixed WHOWAS command reply calling. Affected file
1587 lib/silcclient/command_reply.c.
1589 * Removed all references to silc_idlist_get_client from the
1590 Irssi SILC client since that call is internal call used by
1591 the library. The Irssi SILC client will use now client
1592 retrieval functions found in silcapi.h.
1594 * Fixed a bug in resolving nickname info before sending
1595 private message. It used freed memory. Affected file
1596 irssi/src/silc/core/silc-servers.c.
1598 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Assure my_channels statistics cannot go negative in server.
1601 Affected files silcd/server.c, silcd/server_util.c.
1603 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1607 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Win32 Toolkit changes. Affected files
1610 win32/silc.dsw, win32/libsilc/libsilc.def,
1611 win32/libsilcclient/libsilc.def,
1612 lib/silcutil/silcutil.c, and
1613 lib/sftp/sftp_fs_memory.c.
1615 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Added silc_net_localip to return local host's IP address.
1618 Affected file lib/silcutil/silcnet.[ch].
1620 * If key exchange or rekey protocol is active for a connection
1621 parse all packets syncronously since there might be packets
1622 in packet queue that we are not able to process without first
1623 processing packets before them. Affected file silcd/server,
1624 lib/silcclient/client.c.
1626 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1627 whether library should continue processing the packet.
1628 Affected file lib/silccore/silcpacket.h.
1630 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1631 SilcSFTPMonitorData to SFTP server to monitor various
1632 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1633 lib/silcsftp/sftp_server.c.
1635 * Added silc_file_size to return file size. Affected file
1636 lib/silcutil/silcutil.[ch].
1638 * Implemented the file transfer support for the client library.

1652 silcd/server.c and silcd/packet_receive.c.
1654 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * Renamed silc_file_read and silc_file_write to functions
1657 silc_file_readfile and silc_file_writefile. Added function
1658 silc_file_open and silc_file_close. Affected files
1659 lib/silcutil/silcutil.[ch].
1661 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Resolve the client info when received private message or
1664 channel message for a client which nickname we don't know.
1665 Affected files lib/silcclient/client_prvmsg.c and
1666 lib/silcclient/client_channel.c.
1668 * Do not crash in /KEY if client is not connected. Affected
1669 file irssi/src/silc/core/silc-channels.c.
1671 * Added SilcClientStatus field to the SilcClientEntry in the
1672 lib/silcclient/idlist.h.
1674 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1675 is incomplete and is being resolved, it won't be resolved
1678 Make sure also that USERS command reply does not resolve
1679 twice information. Affected file is
1680 lib/silcclient/command_reply.c.
1682 Make sure that silc_client_get_clients_by_list does not
1683 resolve twice same information.
1685 * Check for valid client->id in the silc_server_free_client_data.
1686 Affected file silcd/server.c.
1688 * Fixed /GETKEY nick@server not to crash if the server entry
1689 is not found. Affected file lib/silcclient/command.c.
1691 * Fixed the silc_server_check_cmode_rights to check the
1692 requested modes correctly. Affected file silcd/command.c.
1694 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Better checks for non-printable chars in nick added.
1697 Affected file silcd/command.c.
1699 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Call the silc_server_udpate_servers_by_server in the
1702 primary router that comes back online in the backup resuming
1703 protocol. Otherwise it routes packets wrong. Affected file
1704 silcd/server_util.[ch], silcd/server_backup.c.
1706 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1709 lib/silcutil/silcbuffmt.[ch].
1711 * Redefined the SILC packet header to include the padding
1712 length. Affected file lib/silccore/silcpacket.[ch].
1714 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1715 length for maximum padding up to 128 bytes). Affected
1716 file lib/silccore/silcpacket.h.
1718 * Removed all backwards support for old 0.5.x MAC thingies.
1719 The SILC packet header change makes it impossible to be
1720 backwards compatible.
1722 * Send the ENDING packet with timeout in the backup resuming
1723 protocol. This is to assure that all routers has connected
1724 to the primary router. Affected file silcd/server_backup.c.
1726 * Changed the RNG to take the first IV from random data. It
1727 used to take it from zero actually. Changed the RNG also
1728 to use /dev/urandom during session. /dev/random is used
1729 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1731 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Changed the SILC packet header to have the first two bytes
1734 (the packet length) encrypted. Affected files aroung the
1735 code tree, lib/silccore/silcpacket.[ch]. Removed the
1736 SilcPacketCheckDecrypt callback. It is not needed anymore
1737 since the silc_packet_receive_process will determine now
1738 whether the packet is normal or special.
1740 * Implemented the unidirectional MAC keys. Affected files
1741 lib/silcske/silcske.c, silcd/protocol.c and
1742 lib/silcclient/protocol.c.
1744 * Implemented the packet sequence number to the MAC computation.
1745 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1746 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1747 lib/silcclient/protocol.c.
1749 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Allow backup router to announce servers. All servers
1752 announced by backup router are added to the global list
1753 automatically. Update hte server's socket to our primary
1754 router also when backup router announces a server.
1755 Affected file silcd/packet_receive.c.
1757 * Do not update the client->router in the function
1758 silc_server_udpate_clients_by_server if the client is on
1759 global list. We might fail to find any specific server
1760 for locally connected clients and local cell clients. They
1761 should still use the `from' and not `to' as client->router.
1762 This fixes backup router resuming protocol. Affected file
1763 silcd/server_util.c.
1765 * Decrease channel statistics count only if the channel
1766 deletion worked. Affected files are silcd/server.c and
1767 silcd/server_util.c.
1769 * Added silc_server_update_servers_by_server to update origin
1770 of all server entries. Used during backup router protocol.
1771 Affected files silcd/server_util.[ch], silcd/server.c. and
1772 silcd/backup_router.c.
1774 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1775 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1776 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1777 lib/silccrypt/silchmac.c.
1779 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1781 * Assure that router cannot reroute the same channel message
1782 to the sender. Affected file silcd/packet_receive.c.
1784 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Made better checks that the channel message is not sent
1787 to the router it came from. Affected file is
1788 silcd/packet_send.c. Fixed memory leak too.
1790 * Announce informations for incoming router connection, but
1791 only after checking if it is replaced by backup router.
1792 Affected file silcd/packet_receive.c.
1794 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * Fixed the backup resuming protocol to work in multiple
1797 router environment. Affected file silcd/server_backup.c.
1799 * Route packet only to one router in the function
1800 silc_server_packet_send_to_channel. Affected file is
1801 silcd/packet_send.c.
1803 * Fixed silc_server_send_notify_dest to set the broadcast
1804 flag. Fixed the silc_server_send_notify_topic to actually
1805 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1806 Affected file silcd/packet_send.c.
1808 * Changed the SFTP Filesystem interface. Changed the
1809 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1810 the filesystem operation function. The SilcSFTPFilesystem
1811 is now a context that is allocated by all filesystem allocation
1812 functions and it already includes the operations structure
1813 and filesystem specific context. It is given as argument
1814 now to the silc_sftp_server_start. This made the interface
1815 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1816 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1818 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Changed the backup router adding and getting interfaces
1821 in the server. The router that will be replaced by the
1822 specified backup router is now sent as argument. Affected
1823 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1826 * Added silc_net_addr2bin_ne to return the binary form of
1827 the IP address in network byte order. Affected files
1828 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1830 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Check for existing server ID in silc_server_new_server
1833 and in silc_server_connect_to_router_final and remove the
1834 old entry if it exists. Affected file silcd/packet_receive.c,
1837 * Send the channel message always to only one router, either
1838 in upstream or downstream. Affected file is
1839 silcd/packet_send.c.
1841 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Wrote the definition of the backup resuming protocol to the
1844 protocol specification.
1846 * Removed one redundant channel key generation from normal
1847 server during joining procedure. Removed one redundant
1848 channel key sending from server to router during joining
1849 procedure. Affected file silcd/command.c.
1851 * Made minor bugfixes to the backup router resuming protocol.
1852 Affected file silcd/server_backup.c, server.c.
1854 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Added --disable-asm configuration option. Affected files
1857 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1860 * Implemented the backup resuming protocol that is used to
1861 resume the primary router position in the cell after the
1862 primary router comes back online. Affected files
1863 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1864 and silcd/server_util.[ch].
1866 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Sleep two (2) seconds after sending QUIT command to server.
1869 Affected file lib/silcclient/command.c.
1871 * Assure that if outgoing data buffer is pending do not force
1872 send any data. Affected file silcd/packet_send.c.
1874 * Assure that if outgoing data buffer is pending do not force
1875 send any data. Affected file lib/silcclient/client.c.
1877 * Implemented the backup router support when the primary router
1878 goes down. The servers and routers can now use the backup
1879 router as new primary router without loosing connectivity.
1881 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1884 in the server to indicate disabled entry. All data read
1885 from the connection will be ignored and no data is sent
1886 for entry that is disabled. Affected files are
1887 silcd/idlist.h, silcd/server.c.
1889 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1891 * Created SFTP client and server test programs in the
1892 lib/silcsftp/tests directory.
1894 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1896 * Implemented memory filesystem (virtual filesystem) for
1897 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1900 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * Implemented the SFTP (SSH File Transfer Protocol) to the
1903 lib/silcsftp. It includes SFTP client and SFTP server
1906 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * Moved lib/silccore/silcprotocol.[ch] to the
1909 lib/silcutil library.
1911 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1912 take variable argument list pointer as argument. Affected
1913 file lib/silcutil/silcbuffmt.[ch].
1915 * Added silc_buffer_set function that is used to set data
1916 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1917 Affected file lib/silcutil/silcbuffer.h.
1919 * Changed various routines in the core library to use the new
1920 silc_buffer_set instead of allocating new buffer only for
1923 * Added 64-bit value formatting and unformatting support to the
1924 silc_buffer_[un]format routines. Affected file is
1925 lib/silcutil/silcbuffmt.[ch].
1927 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1928 to includes/bitmove.h.
1930 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Fixed channel user mode saving in client library. Affected
1933 file lib/silcclient/command[_reply].c.
1935 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1937 * Defined the file transfer to the SILC Protocol. Added
1938 new packet type SILC_PACKET_FTP and defined File Transfer
1939 Payload. The mandatory file transfer protocol is SFTP
1940 (SSH File Transfer Protocol). Affected file in addition
1941 of the internet draft is lib/silccore/silcpacket.h.
1943 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1944 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1945 is used as part of backup router protocol when the primary
1946 router of the cell is back online and wishes to resume
1947 the position as primary router.
1949 * Redefined the MAC generation keys in the protocol. The
1950 same key is not used anymore in both direction. Both
1951 direction will now use different keys for sending and
1952 receiving. This fixes a potential security flaw. This
1953 change causes incompatibilities in the protocol.
1955 * Redefined also the MAC computation from the packet.
1956 An packet sequence number is now added to the MAC
1957 computation. This prevents possible replay attacks against
1958 the protocol. This change too causes incompatibilities
1961 Added `sequence' field to the SilcPacketContext to hold
1962 the current sequence number for the packet.
1964 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Added `created' field to the SilcIDListData in the file
1967 silcd/idlist.h to indicate the time when the entry was
1970 * Added `created' field to the SilcChannelEntry too. Affected
1971 file silcd/idlist.h.
1973 * Added `creation_time' aguments to all the announcement functions
1974 in the server. If it is provided then only the entries that
1975 was created after the provided time frame are actually
1976 announced. Affected file silcd/server.[ch].
1978 * The protocol says that the Channel ID's IP address must be
1979 based on the router's IP address. Added check for this in
1980 the silc_server_new_channel when processing incoming New Channel
1981 Payload. Affected file silcd/packet_receive.c.
1983 * Print out the correct version with --version in SILC client.
1984 Affected file irssi/src/silc/core/silc-core.c.
1986 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Fixed WHOWAS command to check for completnes of the client
1989 entry always, not just when the command is coming from client.
1990 Affected file silcd/command.c.
1992 * Added new function silc_server_packet_queue_purge to purge the
1993 outgoing data queue to the network. After the function returns
1994 it is guaranteed that the outgoing packet queue is empty.
1995 Affected file silcd/packet_send.[ch].
1997 * Purge the outgoing packet queue in the rekey protocol's final
1998 callback to assure that all rekey packets go to the network
1999 before quitting the protocol. Affected file silcd/server.c.
2001 * Added silc_client_packet_queue_parse as similar function as
2002 in server to the client library. The affected file is
2003 lib/silcclient/client.c.
2005 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Splitted silcd/server.c and created silcd/server_util.[ch]
2008 for utility functions.
2010 * Added new socket flag SILC_SF_DISABLED to indicate that the
2011 connection is open but nothing can be sent to or received from
2012 the connection. Affected file lib/silcutil/silsockconn.[ch].
2013 The checking for disabled socket is checked in the low level
2014 silc_socket_write and silc_socket_read functions.
2016 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2018 * Allow only nicknames and channel names that fits into the
2019 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2021 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * When processing JOIN command reply in server check that if
2024 the channel exists in our global list we'll move it the local
2025 list. Affected file silcd/command_reply.c.
2027 * Fixed the check whether client is joined on the channel already
2028 in JOIN command. Affected file lib/silcclient/command.c.
2030 * Fixed the JOIN command reply to check whether the channel
2031 already exists. Affected file lib/silcclient/command_reply.c.
2033 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Added silc_ske_status_string to map the SKE error numbers
2036 to readable strings. The affected files are
2037 lib/silcske/silcske[_status].[ch].
2039 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Do not show the private channels on the WHOIS channel list
2042 as it is not allowed by the protocol. The affected file is
2045 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Assure that the packet length digged from the actual packet
2048 is something sensible in the silc_packet_decrypt_rest_special
2049 in lib/silccrypt/silcpacket.c.
2051 * Free and NULL the allocated pointer in silc_hmac_alloc if
2052 the HMAC allocation fails. The affected file is
2053 lib/silccrypt/silchmac.c.
2055 * Print the selected security properties to the log files in
2056 the server. Affected file silcd/protocol.c.
2058 * Add SKE's reference counter even if calling the completion
2059 callback manually. Otherwise it goes negative, although it
2060 does not cause any problems. The affected file is
2061 lib/silcske/silcske.c.
2063 * Remove the client entry with short timeout after giving the
2064 KILL command. Affected file lib/silcclient/command.c.
2066 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2067 case all found clients are already disconnected (WHOWAS would
2068 found them) in the server. Affected file silcd/command.c.
2070 * Update the last_receive (time of last data received) to be
2071 updated only when received private or channel message so that
2072 the idle time showed in WHOIS makes more sense.
2074 * Added boolean field `valid' in to the SilcClientEntry in the
2075 client library to indicate whether the entry is valid or not.
2076 This fixes the nickname change bug on channel when changing
2077 the nickname to be same than the old (like nick to Nick) the
2078 nickname formatter doesn't set the new nick anymore to Nick@host.
2079 Affected file lib/silcclient/idlist.[ch].
2081 * Now actually fixed the nickname changing on disconnection.
2082 Added new function silc_change_nick to the Irssi SILC Client.
2083 Affected file irssi/src/silc/core/client_ops.c,
2084 irssi/src/silc/core/silc-nicklist.[ch].
2086 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Check that the public key exists in the GETKEY command before
2089 trying to encode it. Affected file silcd/command.c.
2091 * Print some notifications on received public keys with GETKEY
2092 command in the Irssi SILC Client. Affected files are
2093 irssi/src/fe-common/silc/module-formats.[ch],
2094 irssi/src/silc/core/client_ops.c.
2096 * Use IDENTIFY command to resolve the server information in the
2097 GETKEY command instead of INFO command. Affected file
2098 lib/silcclient/command.c.
2100 * All command reply functions in the client library now calls
2101 the pending command reply callbacks even if an error has
2102 occurred. The server has done this a long time and now it was
2103 time to move the client library to this as well. Now all
2104 errors can be delivered back to the pending command reply
2105 callbacks if necessary. Affected files are
2106 lib/silcclient/command[_reply].[ch].
2108 * Change the nickname on disconnection back to the username
2109 because in reconnect the server will enforce it to it anyway.
2110 Affected file irssi/src/silc/core/silc-servers.c.
2112 * Fixed a config file parsing bug in the Irssi SILC client.
2113 Affected file irssi/src/silc/core/clientconfig.c.
2115 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * When printing the channel mode on JOIN, verify that the
2118 channel key and channel's HMAC are valid. Affected file
2119 irssi/src/silc/core/client_ops.c.
2121 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2124 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2125 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2127 * Removed channel key rekey task deleting from the function
2128 silc_server_save_channel_key. Affected file silcd/server.c.
2129 Added explicit timeout task context instead that is used to
2130 delete the task if we are registering a new task before the
2131 new task has elapsed.
2133 * When channel key rekey occurs the client library now saves
2134 the old channel key for a short period of time (10 seconds) and
2135 is able to use it in case some is still sending channel
2136 messages encrypted with the old key after the rekey. Affected
2137 file lib/silcclient/[idlist.h|client_channel.c].
2139 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * Added check to the silc_server_new_id_real to not accept
2142 new ID if it is the sender's own ID. Affected file is
2143 silcd/packet_receive.c.
2145 * Assure that we do not announce ourself or the one we've
2146 sending our announcements when we're router and are announcing
2147 servers to our primary router. Affected file silcd/server.c.
2149 * Fixed silc_server_command_identify_check_client to assemble
2150 correct WHOIS packet. It send corrupted WHOIS packet and
2151 caused problem with router to router connections. Affected
2152 file silcd/command.c.
2154 Fixed also silc_server_command_whois_check the same way
2155 as for the IDENTIFY command.
2157 * Added new SilcIDListStatus to the server in the SilcIDListData
2158 structure. The status now includes the current status of
2159 the entry (like registered, resolved etc.). Affected file
2160 silcd/idlist.[ch]. Defined a bunch of different status types
2161 as well. This replaced the old boolean registered field as well.
2163 Added resolve_cmd_ident field to the SilcClientEntry structure
2164 too so that if the entry is for example being resolved so
2165 another command may attach to the same pending command reply
2166 without requiring to resolve the same entry again. This concept
2167 should optimize the WHOIS and the IDENTIFY resolving under
2168 heavy load by taking away unnecessary resolving for entries
2169 that are being resolved already.
2171 Added support for adding multiple pending commands for one
2172 command idenfier. Affected file silcd/command[_reply].[ch].
2174 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2175 before deleting the data. Otherwise the hash table will have
2176 freed data in comparison functions. Affected file is
2177 silcd/command_reply.c.
2179 * Fixed silc_idlist_replace_client_id to add the new entry to
2180 the cache with NULL nickname. Otherwise there will be invalid
2181 memory as the nickname after the nickname is freed. Affected
2182 file silcd/packet_receive.c.
2184 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2185 saved into wrong slots because the previous number of entries
2186 was not taken into account. Affected file silcd/idlist.c.
2187 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2189 * If we are router and we receive JOIN notify to a channel that
2190 does not have any users then notified client is marked as the
2191 channel founder, as it is it. The affected file is
2192 silcd/packet_receive.c
2194 * Added to the extended hash table API's table_del_*ext functions
2195 the destructor as argument too, so that the caller can decide
2196 which destructor to use or whether to use destructor at all.
2197 Affected file lib/silcutil/silchashtable.[ch].
2199 * Fixed ID Cache purging. It actually deleted the entries from
2200 the hash table after the data was freed. The hash table ended
2201 up comparing freed memory. The affected file is
2202 lib/silccore/silcidcache.c.
2204 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2206 * Fixed Irssi SILC client's KILL command's HELP syntax.
2208 * The USERS command now resolves the detailed user information
2209 if the userinfo field is missing. Affected file is
2210 lib/silcclient/command_reply.c.
2212 * Do not print error in silc_file_read if the read file does
2213 not exist. Just silently return NULL. Affected file is
2214 lib/silcutil/silcutil.c.
2216 * Fixed the silc_log_output to not wine about NULL filename
2217 and to not create some bogus " " filename. Affected file is
2218 lib/silcutil/silclog.c.
2220 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2222 * Fixed various printing bugs on the user interface in the
2223 Irssi SILC Client. Minor changes that were forgotten from
2226 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Fixed the configure.in.pre and the compilation and distribution
2229 environment to support the new autoconf 2.52. That version is
2230 now required to compile the CVS trunk.
2232 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2235 to generally parse user@fqdn format strings. Affected file
2236 lib/silcutil/silcutil.c.
2238 * Added nickname_format and nickname_force_format fields to the
2239 SilcClientParams structure. The first one defines the format
2240 for the nicknames that the library will enforce if the receives
2241 multiple same nicknames. The second one is boolean value and
2242 can be used to force the library to always enforce the format
2243 to the nicknames regardles whether there are multiple nicknames
2244 or not. This configurable formatting was employed to flexibly
2245 support accessing multiple nicknames from the user interface.
2246 The userinterface can now set the nicknames to what ever format
2247 they prefer. Affected file lib/silcclient/silcapi.h.
2249 Added function silc_client_nickname_format to the file
2250 lib/silcclient/idlist.c. It performs the nickname formatting.
2252 Added new field `hostname´ to the SilcClientEntry context.
2253 It holds the hostname of the client. Affected file is
2254 lib/silcclient/idlist.h.
2256 * Irssi SILC Client sets the nicknames in nick@hostn format.
2257 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2258 irssi/src/silc/core/silc-core.c.
2260 The WHOIS printing now also shows both the real nickname and
2261 the formatted nickname so that user knows how to access the
2262 user if there are multiple same nicknames cached. Affected
2263 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2264 printing formatting too to take the hostname now as a separate
2265 argument. The Affected file is
2266 irssi/src/fe-common/silc/modules-formats.[ch].
2268 * Changed the silc_client_get_clients_local to accept the formatted
2269 nickname as argument. It accepts the real nickname too but the
2270 formatted nickname can be used to find the true entry from
2271 multiple entries. Affected file lib/silcclient/silcapi.h and
2272 lib/silcclient/idlist.c.
2274 * Added nickname_format_parse field to the SilcClientParams.
2275 It is a callback function provided by the application to parse
2276 the nickname out of the formatted nickname string. The library
2277 calls it to get the nickname from the formatted string. Since
2278 the application generally knows better the format of the nickname
2279 string it parses it instead of the library, even though library
2280 encodes the formatted string. If the callback function is not
2281 provided then the library will use the string as is. The
2282 affected file is lib/silcclient/silcapi.h.
2284 * All the nickname strings passed to the client library in
2285 commands are now expected to be formatted nickname strings.
2286 If the command does not support the formatted nickname string
2287 it will assume that the sent string is the actual nickname.
2288 Affected file lib/silcclient/command.c.
2290 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Added public key authentication support to OPER and SILCOPER
2293 commands in the client library. Affected file is
2294 lib/silcclient/command.c.
2296 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Changed the get_auth_methdod client operation to be asynchronous.
2299 It can be async if the application resolves the authentication
2300 method from the server during the negotiation. Added new
2301 SilcGetAuthMeth completion callback that the application will
2302 call after resolving the authentication method.
2304 Added function silc_client_request_authentication_method that
2305 the application can use to resolve the authentication method
2306 from the server. Added also SilcConnectionAuthRequest callback
2307 that the library will call after the server has replied. The
2308 application can call this function if it does not know the
2309 current authentication method.
2311 Affected files are lib/silcclient/client.c and
2312 lib/silcclient/silcapi.h.
2314 * The Irssi SILC client now automatically resolves the authentication
2315 method incase any configuration information is not present (and
2316 currently there never is). The affected file is
2317 irssi/src/silc/core/client_ops.c.
2319 * Fixed public key authentication from the client library.
2320 Affected file lib/silcclient/protocol.c. Changed also the
2321 protocol specification about the public key authentication in
2322 the connection authentication protocol. The actual data to be
2323 signed is now computed with a hash function before signing.
2325 * Fixed the public key authentication from the server as well.
2326 Affected file silcd/protocol.c.
2328 * Removed the mlock()'s from the memory allocation routines.
2329 Affected file lib/silcutil/silcmemory.c. The ./configure does
2330 not check anymore for the mlock(). Affected file is
2333 * Fixed USERS command in server to allow the execution of the
2334 command for private and secret channels if the client sending
2335 the command is on the channel. Affected file silcd/command.c.
2337 * Fixed silc_client_get_clients_local to return the clients
2338 count correctly. It could return wrong value. Affected file
2339 lib/silcclient/idlist.c.
2341 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2344 types. The assembler optimizations seemed not to like 64-bit
2345 data types. The assmebler optimizations thus are now enabled
2346 also for BSD systems as opposed to only enable them for Linux.
2348 * Do not check for threads at all on BSD systems. Affected
2349 file configure.in.pre.
2351 * Removed -n and -h options from the Irssi SILC Client since
2352 they are not used in silc.
2354 * Fixed the prime generation to assure that the first digit
2355 of the generated random number is not zero since our conversion
2356 routines does not like number strings that starts with zero
2357 digit. If zero digit is seen the random number is regenerated.
2358 This caused some corrupted RSA keys when the zero first digit
2359 was met. Affected file lib/silcmath/silcprimegen.c.
2361 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2363 * Fixed WIN32 configuration in the ./configure script.
2364 Fixed to include xti.h on environments that has it.
2365 Patches by Carsten Ilchmann and andrew.
2367 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Changed the silc_id_create_client_id to be collision
2370 resistant. It is now assured that there cannot be created
2371 two same client ID's. I suspect that some weird bugs in
2372 the server were actually caused by duplicate Client IDs.
2373 Affected file silcd/serverid.[ch]. A router receiving
2374 new ID now also assures and informs the sending server
2375 if the ID caused collision.
2377 * Changed the silc_id_create_channel_id to also assure that
2378 there are no collisions.
2380 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Statement about ignoring the Mutual Authentication flag when
2383 performing rekey with PFS was a bit misleading. It is ignored
2384 if it was set in the initial negotiation, it cannot be even
2385 set in the rekey. Fixed in the ke-auth draft. Started the
2386 new versions of the protocol drafts in the doc/.
2388 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Fixed a bug in silc_client_command_identify_save when saving
2391 new channel information. The channel name was no duplicated
2392 and caused crash on exit. Affected file is
2393 lib/silcclient/command_reply.c.
2395 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2397 * Fixed the getkey command handling in the server. Send just
2398 empty OK reply to the sender if the key could not be fetched
2399 (but everything else was ok, like the key just was not available).
2400 Changed the public key parameter to optional in the protocol
2401 specs so that empty OK reply can be sent. Affected file
2404 Added a message to Irssi SILC client to tell to user if the
2405 server did not return a public key.
2407 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Fixed a channel key regeneration bug. It registered new
2410 timeout tasks exponentially until all system resources were
2411 used. Affected file silcd/server.c.
2413 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2415 * Added the SILC Document generator to the scripts/silcdoc.
2416 It can be used to generate the Toolkit Reference Manual out
2417 of the source tree. Internally it will also use the RoboDoc
2418 generator now imported in util/robodoc.
2420 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Added couple of return's in rekey protocol if error orccurred
2423 during the protocol. The execution must be terminated.
2424 Affected file silcd/protocol.c. Also, terminate the protocol
2425 always with timeout.
2427 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * The client's Client ID was created initally from the wrong
2430 nickname (it could have been in format nick@host) in the
2431 silc_server_new_client. Affected file silcd/packet_receive.c
2433 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Added some SILC_LOG_ERROR's to various error conditions
2436 if client could not be added to ID cache. Affected files
2437 silcd/packet_receive.c and silcd/server.c.
2439 * When client's sock->user_data is freed, NULL also the
2440 client->router and client->connection pointers. Added check
2441 for these pointers being NULL to various places around the
2442 code. Affected file silcd/server.c.
2444 * Added client->data.registered == TRUE checks to various
2445 places around the code to assure that unregistered client's
2446 are not handled when it is not allowed. Affected file
2449 * Added `bool registered' fields to all
2450 silc_idlist_[server|client]_get_* routines to indicate whether
2451 the fetched client needs to be registered or not. Affected
2452 file silcd/idlist.[ch].
2454 * Add your own entry as registered to the ID cache in the
2455 server. Affected file server.c.
2457 * Fixed a bug in silc_server_new_server. The SilcServer was
2458 set as the new server's context instead of SilcServerEntry.
2459 This naturally caused some weird bugs.
2461 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Do not delete the channel rekey task when adding it
2464 for in silc_server_create_channel_key.
2466 * Changed the silc_server_create_channel_key to return
2467 TRUE or FALSE to indicate the success of the channel key
2470 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Fixed MSVC++ project files and added missing files to
2473 Makefiles under win32/.
2475 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Do not add TCP_NODELAY flag if the operating system
2478 does not have it defined. Affected files are
2479 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2481 * Fixed buffer overflow from Irssi SILC Client. Affected
2482 file irssi/src/fe-common/core/themes.c.
2484 * Fixed double free in client library in the file
2485 lib/silcclient/client.c when disconnecting from server.
2487 * Applied double free patch from cras to Irssi SILC client.
2488 Affected files irssi/src/core/[modules/expandos].c
2490 * Fixed the disconnection handling to Irssi SILC Client.
2491 The application must call silc_client_close_connection
2492 in ops->connect client operation in case of failure of
2493 the connection. Affected file is
2494 irssi/src/silc/core/client_ops.c.
2496 * Do not set sock->protocol to NULL in the function
2497 silc_client_close_connection after executing the protocol's
2498 final callback since the sock might not be valid anymore.
2499 Affected file lib/silcclient/client.c.
2501 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Do not enable SILC_THREADS if the linking with libpthread
2504 did not happen. Affected file configure.in.pre.
2506 * Added notion to protocol specification that server must
2507 verify the sent authentication payload with CMODE when
2508 setting the channel founder key. Implemented it to the
2509 server. Affected file silcd/command.c.
2511 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Added _EXTRA_DIST SILC distribution variable to the
2514 distributions file. It is used to conditionally add extra
2515 files or directories to the specific distribution. Affected
2516 files ./prepare, Makefile.am.pre and distributions.
2518 Removed the `_' from the start of the distribution names.
2521 * Added README.WIN32 for instructions to compile the Toolkit
2524 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Fixed a double free in disconnection in the server. Affected
2527 file is silcd/server.c.
2529 * Fixed the lib/silcske/groups.c to work now also with GMP
2530 MP library. The string conversion did not work when using
2531 specific base and the base is indicated in the string as well.
2533 * Created win32/ directory which now includes MSVC++ specific
2534 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2535 It will appear only in the toolkit distribution
2537 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Changed the key material distribution function in case when
2540 the hash output is too short. The data is now concatenated
2541 a bit differently than it used to. Made the change to the
2542 SKE protocol specification.
2544 * Added better GMP detection to configure.in.pre. A patch
2547 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Fixed a minor bug in SKE that might cause some problem on
2550 some platforms. Affected file lib/silcske/silcske.c.
2552 * Added the cookie checking for initiator in the SKE. It checks
2553 that the responder returns the sent cookie unmodified. The
2554 affected file is lib/silcske/silcske.c. Added new SKE
2555 error type INVALID_COOKIE that can be sent during the
2556 negotiation. Fixed some memory leaks as well.
2558 * Added the "invalid cookie" error message to Irssi SILC client's
2561 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Added `task_max' field to the SilcClientParams to indicate
2564 the maximum tasks the scheduler can handle. If set to zero,
2565 default values are used. Affected file lib/silcclient/silcapi.h.
2567 * Fixed memory leaks in silc_client_close_connection. Affected
2568 file lib/silcclient/client.c.
2570 * Added silc_client_del_client_entry to client library to free
2571 all memory of given client entry. Affected file is
2572 lib/silcclient/idlist.[ch].
2574 * Added new functions silc_client_del_channel and
2575 silc_client_del_server to delete channel and server entries.
2576 Affected file lib/silcclient/[silcapi.h/idlist.c].
2578 * Removed silc_client_del_client_by_id from silcapi.h.
2580 * Fixed the INFO command to return the server's own info
2581 correctly when querying by Server ID. Affected file is
2584 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Removed the non-blocking settings in WIN32 code in the
2587 silc_sock_[read/write] and added SleepEx instead. Affected
2588 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2589 of input data is now checked with FIONREAD and ioctlsocket.
2591 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Call silc_schedule_task_del_by_context in the
2594 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2595 Affected file lib/silccore/silcprotocol.c.
2597 * Call silc_protocol_cancel for active protocols in the
2598 silc_server_close_connection if the funtion
2599 silc_server_free_sock_user_data has not been called.
2600 Affected file silcd/server.c.
2602 * Generic tasks cannot be deleted using the del_by_fd
2603 task deleting function since generic tasks does not match
2604 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2606 * Added a notion to SILCOPER help file that the SILCOPER works
2607 only on router server, not on normal server.
2609 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Added for WIN32 support for the new scheduler as well.
2612 Affected file lib/silcutil/win32/silcwin32schedule.c.
2614 * Fixed the SHA1 implementation to work on various platforms.
2616 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2618 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2619 API. It is part of the scheduler now. Everything else is
2620 as previously but some functions has changed their names.
2621 Checkout the lib/silcutil/silcschedule.h for the interface.
2622 Updated all applications to use the new interface. Affected
2623 files are lib/silcutil/silcschedule.[ch].
2625 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2627 * Found a bug in the SKE implementation. The HASH value,
2628 specified by the protocol, was not computed correctly. The
2629 public key of the responder was not added to the computation
2630 even though it is mandatory. Affected file lib/silcske/silcske.c.
2631 This unfortunately causes incompatibilities with older
2632 clients and servers.
2634 * Added WIN32 specific network init and uninit functions:
2635 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2636 the Winsock2. Affected file lib/silcutil/silcnet.h and
2637 lib/silcutil/win32/silcwin32net.c.
2639 * Set the socket always to nonblocking mode on WIN32 after
2640 reading data or writing data. Affected file is
2641 lib/silcutil/win32/silcwin32sockconn.c.
2643 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2645 * Fixed various compilation problems under WIN32. Affected
2646 files lib/silcutil/win32/silcwin32thread.c and
2647 lib/silcutil/win32/silcwin32schedule.c.
2649 * Removed all _internal.h #includes from public header
2650 files. Internal headers must never be included from
2653 Removed also the lib/silcske/payload_internal.h file.
2655 * All include files that may be needed (public and some others
2656 included by the public headers) by application developers are
2657 now copied to the ./includes directory. It does not copy any
2658 internal headers. Affected file Makefile.defines.pre and all
2659 Makefile.am's under lib/ and subdirs.
2661 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Do not change the ~/.silc directory's permissions automatically.
2664 Affected file irssi/src/silc/core/clientutil.c.
2666 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Do not cancel the protocol in silc_server_close_connection
2669 it might cause recursion. Now cancelled in the function
2670 silc_server_free_sock_user_data. Affected file silcd/server.c.
2672 * Fixed the silc_server_remove_clients_by_server to regenerate
2673 the channel keys correctly finally. Added also new function
2674 silc_server_remove_clients_channels to actually do it.
2675 Affected file silcd/server.c.
2677 * Fixed the silc_server_new_channel to not crash by giving
2678 wrong router to the new channel. Affected file is
2679 silcd/packet_receive.c.
2681 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2684 which is given as argument to the silc_client_alloc now.
2685 It can be used to configure the client and set various parameters
2686 that affect the function of the client.
2688 * The USERS command in server did not check whether the channel
2689 is private or secret. Affected file silcd/command.c.
2691 * Added new argument to the USERS command in protocol specification.
2692 The USERS command now can take the channel name as argument
2693 as well. Added support for this in client and server and
2694 updated the protocol specs.
2696 * Completed the GETKEY command in client. It can be now used
2697 to fetch also servers public key not only some clients.
2698 Affected files lib/silcclient/command[_reply].c.
2700 * Added silc_client_get_server to return server entry by the
2701 server name. Affected files lib/silcclient/silcapi.h and
2704 * Redefined the IDENTIFY command in protocol specification to be
2705 more generic. It now can be used to query information about
2706 any entity in the SILC Network, including clients, servers and
2707 channels. The query may be based either the entity's name
2708 or the ID. Added support for this in both client and server.
2710 Affected files silcd/command.c and lib/silcclient/command.c
2711 and command_reply.c.
2713 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2714 the _from_client and _from_server functions. Affected file
2717 * Added silc_client_get_channel_by_id_resolve to the file
2718 lib/silcclient/silcapi.h to resolve channel information by
2719 its ID. Added also silc_client_get_channel_by_id that
2720 does not resolve it from the server.
2722 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Added SilcServerEntry context into the client library
2725 to represent one server. The INFO command now allocates
2726 these to save the resolved server info. For now on the
2727 client library will also keep information about servers,
2728 connected and resolved with INFO.
2730 The INFO command now allocates the SilcServerEntry context
2731 and saves the server info there. The COMMAND_REPLY in
2732 the INFO now returns the parameters to application in
2733 same order as defined in the protocol specification.
2735 The entries are cached in the client->server_cache.
2737 * The INFO command is now issued after received the Client ID
2738 from the server. Affected file lib/silcclient/client.c.
2740 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2741 to the application as the mode changer might be server.
2742 It is guaranteed that NULL is not returned anymore to the
2743 application. Affected file lib/silcclient/client_notify.c.
2745 The ID Type is now also passed to the application so that
2746 it can check whether the returned entry is SilcClientEntry
2749 Added new function silc_client_get_server_by_id to return
2750 the server entry by ID. Affected files are the
2751 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2753 * Do not create the channel in the Irssi SILC Client when issuing
2754 the JOIN command but when received the sucessful JOIN command
2755 reply. Otherwise the channel might get created even though we
2756 could not join it. The Affected file is
2757 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2759 * Fixed a channel joining bug in router. The router must also
2760 check the channel modes, invite and ban lists etc. when serving
2761 the JOIN command sent by normal server. Affected file is
2762 silcd/command.c. The router now resolves the client's
2763 information from the server who sent the JOIN command if it
2764 does not know it, and processes the JOIN command only after
2767 * Changed the SilcCommandCb to take new argument; void *context2.
2768 Affected file lib/silccore/silccommand.h
2770 The second argument in the command callbacks in the server now
2771 includes the SilcServerCommandReplyContext if the command was
2772 called as pending command callback from the command reply.
2773 Otherwise it is NULL. When called as pending the status of the
2774 command reply will be checked and if it was erronous the
2775 error will be sent to the original sender of the command.
2776 This way the client always receives the error messages even
2777 though the server was actually the one who received the error
2778 when it resent the command to router, for example. Affected
2779 files silcd/command[_reply].[ch].
2781 * Fixed sending WHOWAS command's error message to client if
2782 the requested client could not be found. It was missing.
2785 * Changed the CMODE and CUMODE commands reply arguments in the
2786 protocol specification. The Channel ID is now sent in both
2787 of the commands to identify the channel. Implemented this
2788 new feature to the client and server. Affected files
2789 lib/silcclient/command_reply.c and silcd/command.c.
2791 * Made better checks for invite and ban lists in the JOIN
2792 command in server. Affected file silcd/command.c.
2794 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2796 * The server now performs the incoming host IP/DNS lookup
2797 using the silc_socket_host_lookup and thus does not block
2798 the server anymore. Affected file silcd/server.c.
2800 * Completed the multi-thread support for SILC Scheduler in
2801 the lib/silcutil/silcschedule.c.
2803 * Fixed the configure.in.pre to detect the pthread correctly
2806 * Fixed a deadlock in silc_task_queue_wakeup in the file
2807 lib/silcutil/silctask.c.
2809 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * Added new function silc_schedule_wakeup that is used in
2812 multi-threaded environment to wakeup the main thread's
2813 schduler. It needs to be used when a thread adds a new task
2814 or removes a task from task queues. After waking up, the
2815 scheduler will detect the task queue changes. If threads
2816 support is not compiled in this function has no effect.
2817 Implemented the wakeup mechanism to both Unix and WIN32
2818 systems. Affected files are lib/silcutil/silcschedule.[ch],
2819 lib/silcutil/unix/silcunixschedule.c and the
2820 lib/silcutil/win32/silcwin32schedule.c.
2822 * Added new function silc_task_queue_wakeup to wakeup the
2823 scheduler by the specified task queue. Affected file
2824 lib/silcutil/silctask.[ch].
2826 * The silc_socket_host_lookup_start now wakes up the scheduler
2827 after adding the timeout task. Affected file is
2828 lib/silcutil/silcsockconn.c.
2830 * The silc_socket_host_lookup is synchronous now if the threads
2831 support is not compiled in. However, the callback is still
2832 called asyncronously through the scheduler, anyway. Affected
2833 file lib/silcutil/silcsockconn.c.
2835 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Added new function silc_socket_host_lookup to perform
2838 asynchronous IP and FQDN lookups for the socket connection.
2839 Affected files lib/silcutil/silcsockconn.[ch].
2841 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2844 that may or may not compile the mutex support in.
2846 Changed the silc_mutex_alloc interface. It allocates the
2847 mutex now to the sent pointer and returns TRUE or FALSE.
2849 Affected file lib/silcutil/silcmutex.h.
2851 * Wrote the SILC Task Queue interface to support multi-threads.
2852 Affected file lib/silcutil/silctask.[ch].
2854 * Wrote the SILC Scheduler to support multi-threads. Affected
2855 file lib/silcutil/silcschedule.c.
2857 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2859 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2860 in lib/silcutil/win32/.
2862 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Defined SILC Mutex API and SILC Thread API and implemented
2865 them for Unix. Affected files are
2866 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2867 lib/silcutil/unix/silcunixmutex.c and
2868 lib/silcutil/unix/silcunixthread.c.
2870 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Fixed the silc_server_remove_clients_by_server's channel
2873 key re-generation. The hash table handling was incorrect
2874 and would not work with many channels. Affected file is
2877 * Fixed some memory leaks around the server code.
2879 * Rewrote the silc_server_get_users_on_channel to support IPv6
2880 based Client ID's. Affected file silcd/server.c.
2882 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2883 specification. However, a separate document must be written
2884 to define the detailed signing procedure and the payload
2885 associated with the flag. Defined the flag to the
2886 lib/silccore/silcchannel.h as well.
2888 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Changed the dynamic tables to static size tables in the
2891 lib/silccrypt/silchmac.c.
2893 * Removed GCC dependencies from the code. A patch by cras.
2895 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Do not show the error "Error receiving packet bla bla"
2898 in server if it really was not an error (-2 means that reading
2899 is pending). Affected file silcd/server.c.
2901 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Fixed a possible crash in silc_server_remove_clients_by_server
2904 in silcd/server.c. Fixed there also some memory leaks.
2906 * Fixed the silc_idlist_replace_client_id. It could replace
2907 wrong key in the hash table. Affected file silcd/idlist.c.
2909 * Do not check whether there are global users on the channel
2910 if the channel->global_users is FALSE. Affected functions
2911 silc_server_remove_from_one_channel and
2912 silc_server_remove_from_channels in silcd/server.c. Also,
2913 do not check if the removed client is local as we can be
2914 sure that global client was not removed from the channel
2915 and checking for global users is not needed.
2917 * The silc_server_remove_clients_by_server now re-generates
2918 the channel keys correctly for those channels that had
2919 clients removed from them. Affected file silcd/server.c.
2921 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Found the reason of random crashes in the server. We weren't
2924 ignoring the SIGPIPE signal (which can be sent in write())
2925 and it crashed the server. Affected file silcd/silcd.c.
2927 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Assure that sock->user_data is not NULL in the function
2930 silc_server_packet_send in silcd/packet_send.c.
2932 * Disconnect the remote connection if it could not be added
2933 to any ID lists in the server. The affected file is
2936 * Check in silc_server_packet_send[_real/dest] that the
2937 socket is not disconnecting and ignore the data if it is.
2938 Affected file silcd/packet_send.c.
2940 * Define inline to __inline on native WIN32 compilation.
2941 Affected file includes/silcwin32.h.
2943 * Added some explicit type casts for inline code since MSVC
2944 require them. Affected files lib/silcutil/silcbuffer.h,
2945 lib/trq/silcdlist.h and lib/trq/silclist.h.
2947 * Print warning in log files from now on if the packet
2948 decryption fails. Affected file silcd/server.c.
2950 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Changed the `say' client operation's interface to accept
2953 new `type' argument to indicate the type of the message sent
2954 by the library. The application may filter the library's
2955 messages according the type. The affected file is the
2956 lib/silcclient/silcapi.h.
2958 * Added two new functions to lib/silcclient/silcapi.h:
2959 silc_client_del_client and silc_client_del_client_by_id.
2960 Affected file lib/silcclient/idlist.c.
2962 * Moved the clientincludes.h from includes/ to silc/ and
2963 serverincludes.h from includes/ to silcd/.
2965 * The modes for the CMODE and CUMODE are now passed as
2966 uint32 for application with COMMAND_REPLY. The affected
2967 file is lib/silcclient/command_reply.c.
2969 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * /WHOIS without arguments shows client's own information.
2972 Affected file lib/silcclient/command.c.
2974 * Changed PING to not accept any arguments. The specs
2975 says that client can ping only the connected server so
2976 requiring an argument is not needed. Affected file is
2977 lib/silcclient/command.c.
2979 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Fixed a fatal bug in private message sending and reception
2982 encryption and decryption when using private message keys.
2983 The implementation was incorrect and did not follow the
2984 specification. It causd that some of the message were
2985 lost since it did not use the sending and receiving keys
2986 as the protocol suggests. This has been fixed and will cause
2987 incompatibilities with older clients when sending private
2988 message encrypted with private message keys. Affected files
2989 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2990 and various other in Irssi SILC Client.
2992 Added `responder' boolean argument to the functions
2993 silc_client_add_private_message_key[_ske] to indicate when
2994 the key is added as responder or initiator of the key
2997 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Removed the silc_ske_check_version function and created
3000 a SilcSKECheckVersion callback. Added also a function
3001 silc_ske_set_callbacks that is now used to set all SKE
3002 callbacks. The callback functions are not given to
3003 the SKE functions anymore, but this function is used to
3006 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3008 * Added `silc_version' argument to the silc_client_alloc
3009 to define the version of the application for the library.
3010 The library will use the version string to compare it
3011 against the remote host's (usually a server) version
3012 string. Affected file lib/silcclient/silcapi.h
3014 * Added the KE protocol context to Key Agreement context
3015 in client library so that we can abort the SKE if it
3016 is in process when we get timeout. Affected file is
3017 lib/silcclient/client_keyagr.c.
3019 * Do not resolve the client ID forever if it returns in the
3020 first time that such client does not exist. This was done
3021 for example with private message. Affected file is
3022 lib/silcclient/client_prvmsg.c.
3024 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * Do not add regex.h for WIN32. The affected file
3027 includes/silcincludes.h.
3029 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3030 not work yet 100%. It generates the DLL's automatically
3031 when compiling with --with-win32 under cygwin.
3033 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * lib/contrib/regex.c is not compiled on WIN32.
3037 * Added silc_net_get_socket_opt function to the
3038 lib/silcutil/silcnet.h.
3040 * Added includes/silcwin32.h for WIN32 specific includes
3043 * Do not use ptime structure or any of the posix process
3044 functions on WIN32 in lib/silccrypt/silrng.c.
3046 * Added silc_gettimeofday to provide generic function
3047 for struct timeval on all platforms. Added the function
3048 to lib/silcutil/silcutil.h.
3050 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3053 library as they clearly belong there. As a plus side we
3054 can make the actual socket connection routines platform
3057 Added also new generic function silc_socket_read and
3058 silc_socket_write (that used to be silc_packet_[read/write].
3059 The implementation of these are platform specific.
3061 * Added WIN32 specific routines of silc_socket_[read/write]
3062 to lib/silcutil/win32/silcwin32sockconn.c.
3064 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Added preliminary support for native WIN32 compilation under
3067 cygwin (using the -mno-cygwin option for GCC) to the
3068 ./configure.in.pre. The --with-win32 now prepares the
3069 compilation for native WIN32.
3071 * Rewrote the SILC Scheduler interface in the file
3072 lib/silcutil/silcschedule.h. The scheduler is now context
3073 based and does not have anymore any global static scheduler.
3074 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3075 and created lib/silcutil/win32 directory for WIN32 based
3078 * Added Unix specific network routines to the
3079 lib/silcutil/unix/silcunixnet.c and the old
3080 lib/silcutil/silcnet.c includes now only generic routines.
3082 Added WIN32 specific network routines to the
3083 lib/silcutil/win32/silcwin32net.c.
3085 * Added Unix specific utility functions from the
3086 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3088 * Added WIN32 SILC Scheduler to the file
3089 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3092 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Do not handle JOIN notify in the server if the target client
3095 is not registered (idata->registered == FALSE). The affected
3096 file is silcd/packet_receive.c.
3098 * Update the nickrec->founder in event_cumode in the Irssi SILC
3099 client. Affected file irssi/src/silc/core/silc-channels.c.
3101 * Fixed the CUMODE_CHANGE notify handling in the server when
3102 server and router are announcing their clients on channels.
3103 Now the mode changes are saved and notified correctly. The
3104 affected file is /silcd/packet_receive.c.
3106 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3107 They really did not replace the cache entry in the ID Cache.
3108 Now they do that. Affected file silcd/idlist.c.
3110 * Fixed the KICK notify handling in the Irssi SILC client to
3111 update the channel records so that the kicked client does not
3112 appear to be on the channel. The affected file is
3113 irssi/src/silc/core/silc-channels.c.
3115 * Always update the conn->current_channel when executing command
3116 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3118 * Fixed the KILL notify handling in Irssi SILC client to remove
3119 the killed client on all channels.
3121 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Fixed the silc_parse_command_line to remove extra spaces
3124 from the start and end of the arguments. Affected file is
3125 lib/silcutil/silcutil.c.
3127 * Cancel and free any active protocol in the function
3128 silc_server_close_connection. Affected file silcd/server.c.
3130 * Cancel and free any active protocol in the function
3131 silc_client_close_connction. Affected file is
3132 lib/silcclient/client.c.
3134 * Do not execute the KILL command for clients that are in
3135 history (ie. they are not in the network). Affected file is
3138 * Fixed KILL notify handling, client does not crash anymore.
3139 Affected file irssi/src/silc/core/silc-channels.c.
3141 * Reduced the default packet buffer size from 2048 to 1024 in
3142 lib/silccore/silcpacket.c.
3144 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3145 counter to the SKE context that is incresed when the SKE library
3146 performs async operation outside the library. If the outside
3147 process frees the SKE context and FREED status will be set
3148 and the library will detect after the sync operation that the
3149 libary is freed. The affected files are
3150 lib/silcske/silcske[_status].[ch].
3152 * Resolve the client entry information in the function
3153 silc_client_channel_message to assure that NULL pointer is not
3154 passed as client entry to the application. */
3156 * Fixed the task timeout calculation to assure that there is
3157 never negative timeouts. The affected file is
3158 lib/silcutil/silcschedule.c.
3160 * Fixed the channel user mode notification sending in server.
3161 It was sent point-to-point to the router (or to server by router)
3162 but it needs to be destined to a channel. The routines now
3163 supports sending the channel user mode notifys to the channels
3164 when announcing clients and channels. Affected files are
3165 silcd/server.c and silcd/packet_receive.c.
3167 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3168 It did not actually replace the old channel entry in the cache.
3169 Affected file lib/silcclient/client_notify.c.
3171 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3173 * Fixed a possible crash in silc_packet_send_prepare. It now
3174 assures always that there is enough space in the buffer and
3175 at the tail area of the buffer (for MAC).
3177 Fixed the inbound buffer reallocation in silc_packet_read.
3178 It was old code and did not handle the reallocation correctly.
3181 The affected file is lib/silccore/silcpacket.c.
3183 * Fixed buffer overflow in silc_parse_nickname in the file
3184 lib/silcutil/silcutil.c.
3186 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3188 * make install generates new server keys only if there is not
3191 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3193 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3194 Added check that if the NOREPLY is set then we will not send
3195 the away message. This avoids infinite loop of away messages
3196 if both clients are away. The affected file is
3197 lib/silcclient/client_prvmsg.c.
3199 * Fixed client crash if /NICK was given without arguments.
3200 Affected file lib/silcclient/command.c.
3202 * Server does not send the invite list in INVITE command back
3203 to the client if the list was not altered. Added this notion
3204 to the protocol spec as well. Affected file silcd/command.c.
3206 Fixed possible crash in INVITE command by checking the
3207 value of silc_server_get_client_route command.
3209 * Fixed the INVITE notify type handling. The arguments are now
3210 taken in correct order and client does not crash. The affected
3211 file is irssi/src/silc/core/silc-channels.c.
3213 Removed the "Inviting xxx to channel" message from the
3214 client library away and let the application handle it.
3215 Affected file lib/silcclient/command.c. Added that message
3216 to Irssi SILC client's message formats.
3218 * Fixed CMODE command crash in client. It now checks the
3219 amount of arguments correctly and does not crash. The affected
3220 file is lib/silcclient/command.c.
3222 * Do not create new channel automatically in silc_channels_join
3223 but check whether the channel by that name already exists.
3224 Affected file irssi/silc/core/silc-channels.c.
3226 * Do not send the SERVER_SIGNOFF to router if the disconnected
3227 entity was the router. Affected file silcd/server.c.
3229 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3230 SILC client as it was missing from there.
3232 Added the handling of the KICK notify to the Irssi SILC client
3233 as it was missing. Added "you have been kicked" message to
3234 Irssi SILC client's message modules formats.
3236 Added the handing of the KILL notify to the Irssi SILC client
3237 as it was missing. Added the kill message module formats
3240 The affected file is irssi/src/silc/core/silc-channels.c.
3242 * The router did not save the channel mode the server announced.
3243 Affected file silcd/packet_receive.c.
3245 * Fixed a possible crash in INFO command in server. If the
3246 server did not provide the server info it crashed. Affected
3247 file silcd/command.c.
3249 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Fixed the GETKEY command in the server to check also the
3252 global list. Otherwise the GETKEY would not work correctly
3253 in normal SILC server. Affected file silcd/command.c.
3255 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Fixed GETKEY crash, it crashed if the command did not succseed.
3259 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3262 is now real and not just an macro interface to GMP.
3264 Removed the entire GMP from the source tree and imported new
3265 NSS MPI library instead. Reason for removing GMP is that it is
3266 extremely large and compiles extremely slow. The NSS MPI
3267 is only a few files and compiles in less than 10 seconds.
3268 The speed is also about the same as GMP. The MPI is imported
3269 to lib/silcmath/mpi.
3271 If the system has GMP installed we will still use the GMP.
3272 If it is not then the NSS MPI will be compiled.
3274 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Merged a long nickname (127 characters long) crash bugfix from
3277 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3279 * Merged a freed memory reference bugfix from Irssi CVS tree.
3280 Affected file irssi/src/core/commands.c.
3282 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Added the server's public key sving and verification to the
3285 server when performing the SKE. This was missing and the
3286 remote server's (or router's) public key was accepted without
3287 checking whether we have it previously or trust it at all.
3288 Affected file silcd/protocol.c.
3290 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Check in the silc_server_timeout_remote if protocol is active
3293 and make sure that the protocol's final callback is called so
3294 that all memory if freed. Affected file silcd/server.c.
3296 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * silc_server_whois_send_reply crashed the server if the nickname
3299 was 127 characters long. Affected file silcd/command.c.
3301 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Added sanity check to the silc_server_new_client. If the hostname
3304 is provided inside username then check that the provided hostname
3305 really is the same as the resolved one. If the hostname was not
3306 resolved then check it from the public key. Affected file is
3307 silcd/packet_receive.c.
3309 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3310 if the server disconnected us and the connection is not valid
3311 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3313 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3314 the library to the lib/silcutil/silcutil.[ch].
3316 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Close log file after open. Affected file
3319 lib/silcutil/silclog.c.
3321 * Check whether sock == NULL in silc_client_send_packet and return
3322 if it is. Affected file lib/silcclient/silcclient.c.
3324 * Check rec->entry == NULL in the Irssi SILC Client before
3325 sending the channel message. Affecte file is
3326 irssi/src/silc/core/silc-servers.c.
3328 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Merged a splitted window bugfix from Irssi CVS tree. The
3331 affected file is irssi/src/fe-text/textbuffer-view.c.
3333 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3334 It did not print nickname.
3336 * Improved the distributions system a bit.
3338 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3341 irssi/src/fe-text/gui-window.c.
3343 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3344 to in-active server. The affected file is
3345 irssi/src/silc/core/client_ops.c.
3347 * Resolve the client in USERS command reply if the entry does
3348 not have username resolved. The affected file is
3349 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3350 command to WHOIS command to really resolve stuff. The USERS
3351 is not used any more in any critical section so WHOIS can
3352 be used even though it might be slower than IDENTIFY.
3354 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3357 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Changed the protocol API a bit more consistent in the
3360 lib/silccore/silcprotocol.[ch].
3362 * Changed the following headers to ROBODoc format:
3364 lib/silccore/silcpayload.h
3365 lib/silccore/silcprotocol.h
3366 lib/silccore/silcsockconn.h
3368 All core library headers are now formatted.
3370 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Fixed a bug in Irssi SILC client; do not show that you are
3373 server/router operator if you really are not. Affected file is
3374 irssi/src/silc/core/client_ops.c.
3376 * Renamed silc_command_free_payload to silc_command_payload_free.
3377 Affected file lib/silccore/silccommand.h
3379 * Added silcmath.h to include the prototoypes of various routines
3380 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3383 * Changed the following headers to ROBODoc format:
3385 lib/silccore/silcchannel.h
3386 lib/silccore/silccommand.h
3387 lib/silccore/silcid.h
3388 lib/silccore/silcidcache.h
3389 lib/silccore/silcmode.h
3390 lib/silccore/silcnotify.h
3391 lib/silccore/silcpacket.h
3392 lib/silcmath/silcmath.h
3394 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Added checking to the server code not to start the server if
3397 ciphers and stuff are not configured properly. Affected files
3398 silcd/serverconfig.[h] and silcd/server.c.
3400 * Changed the layout of the header files of the public interfaces
3401 in the SILC libraries. The new layout supports ROBODoc
3402 documentation tool (and some others) so that it is easy to create
3403 a library reference manual. All the other headers and source
3404 code must still follow the CodingStyle document. Also source
3405 code must not include these ROBODoc stuffs, only the headers.
3406 Furthermore, all public interface headers must now be named
3407 by using `silc' prefix, example: silcapi.h, silccipher.h.
3408 Some files were renamed due to this. All the other headers
3409 must not be used as public interfaces. I will update the
3410 CodingStyle document later. Changed following headers, so far:
3412 lib/silcclient/silcapi.h
3413 lib/silccore/silcauth.h
3414 lib/silccore/silcprivate.h
3415 lib/silccrypt/silcdh.h
3417 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Removed silc_client_packet_send_flush from the client library
3422 as it is not needed. Affected file lib/silcclient/client.[ch].
3424 * Added printing of message of unresolved authentication method
3425 to the Irssi SILC client. Added it to the module formats.
3426 Removed the same message from the client library.
3428 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Added new distribution feature, DISTLABEL. Every distribution
3431 can define own preprocessor label that can be used in the
3432 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3433 file distributions, acconfig.h.pre and prepare.
3435 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Added Makefile.defines_int to include the actual definitions
3438 for Makefile.defines.in. Tested the new distribution system,
3439 created distributions and tested installation.
3441 * Added AWAY message printing to the Irssi SILC client. Added
3442 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3444 * Added SCONNECT command to call the SILC's CONNECT command.
3445 Cannot use CONNECT directly since Irssi uses that internally.
3446 Affected file irssi/src/silc/core/silc-servers.c.
3448 Added ACTION local command. It is same as ME command but takes
3449 the channel as mandatory argument.
3451 Rewrote some of the Irssi's help files to suite for SILC
3454 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Added Makefile.defines[.in] that should for now on be included
3457 in all Makefile.am file in the source tree. That file includes
3458 all common compilation definitions for SILC source tree.
3460 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Minor changes to the ./prepare script to change the package
3463 name according the distribution name to the configure.in.
3465 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Created new distribution system. Added file `distributions'
3468 that defines all the distributions that can be created out of
3469 the SILC source tree. The ./prepare script now reads that
3470 file to determine how to prepare the distributions. The
3471 first argument to the ./prepare is the name of the distribution
3472 and second is the version of the distribution. If given
3473 without arguments it creates the default (toolkit) distribution
3474 with the default version (defined in ./prepare).
3476 All Makefile.am files that are subject to the distributions
3477 are now named as Makefile.am.pre. These are ./Makefile.am
3478 and lib/Makefile.am. Others may be changed later.
3480 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Added invite list, ban list, some key management and connection
3483 error message printing to module formats in the Irssi SILC client.
3485 * Added new silc_client_set_away_message to set the away message
3486 that is back to the person who sent private message. The
3487 affected file lib/silcclient/silcapi.h and the
3488 lib/silcclient/client_prvmsg.c.
3490 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Fixed the private message sending in the Irssi SILC client,
3493 added local command KEY to the Irssi SILC client.
3495 Added key management and key agreement message formats to the
3496 irssi/src/fe-common/silc/module-formats.[ch].
3498 Added USERS (alias WHO) printing, server/router operator
3499 indication and LIST command printing to the module formats.
3501 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Fixed channel joining notify handling, cumode notify handling
3504 from Irssi SILC client.
3506 * Added SILC specific module-formats to the Irssi SILC client so
3507 that SILC specific message hilighting, colors etc is possible.
3508 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3510 Added channel mode, channel user mode, actions, notices,
3511 whois and whowas printing to the the module-formats.c.
3513 * Fixed a bug in channel deletion in the server. The channel
3514 is not left to the cache even if the channel founder auth mode
3515 is set when there are no users anymore on the channel. Affected
3516 file silcd/server.c.
3518 * The silc_net_localhost now resolves the entire hostname including
3519 the domain name. Affected file lib/silcutil/silcnet.c.
3521 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3523 * Changed the ask_passphrase client operation to be ascynchronous.
3524 It has now a completion callback and a context that the
3525 application must call after it has got the passphrase from
3526 the user. Affected files lib/silcclient/silcapi.h,
3527 lib/silcclient/protocol.c, lib/silcclient/command.c and
3530 Added SilcAskPassphrase callback that the application calls
3531 to deliver the passphrase to the library.
3533 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3534 The public key verification and especially a certificate
3535 verification is asynchronous procedure.
3537 Added new SILC_SKE_STATUS_PENDING status to indicate the
3538 request is pending and a callback will be called to finalize
3541 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3542 indicate that remote end did not send its public key (or
3543 certificate), even though we require it. Added check for this
3544 condition in the SKE. This was a security bug, now fixed.
3546 Defined new SilcSKEVerifyCbCompletion callback that is called
3547 when the verification process is completed.
3549 The affected files lib/silcske/silcske_status.h and
3550 lib/silcske/silcske.[ch].
3552 * Changed the verify_public_key client operation to be async
3553 as well. Defined SilcVerifyPublicKey callback that is used to
3554 indicate the success of the public key verification process.
3556 Changed the server and client to use the new async client
3559 * Changed the Irssi SILC client's internal scheduler to be called
3560 twice as many times as it used to be. As a result the client
3561 should be a bit faster now. Affected file is
3562 irssi/src/silc/core/silc-core.c.
3564 * Added support to Irssi SILC client of asynchronous public key
3565 verification and passphrase inquiry. Affected file is
3566 irssi/src/silc/core/silc-core.c.
3568 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Do not say "You have left channel %s" in client library.
3571 Moved it to the application. Affected files are
3572 lib/silcclient/command.c and silc/client_ops.c.
3574 * Fixed silc_client_get_clients. Command context was not
3575 duplicated and was freed memory in the callback. Affected
3576 file lib/silcclient/idlist.c.
3578 * Do not say "you are now talking..." on JOIN command in the
3579 client library. The appliation must handle it.
3581 * Do not say ".. changed topic to" in command reply in the
3582 client libary. The application must handle it.
3584 * Fixed TOPIC command sending in the client library.
3586 * Fixed a memory leak in silc_client_command_free in the file
3587 lib/silcclient/command.c.
3589 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Imported a modified version of Irssi client to the source tree.
3592 The Irssi will be used to create a new client called
3593 Irssi SILC. Imported to irssi/.
3595 Added silc_core_init_finish function to the Irssi. Affected
3596 file irssi/configure.in.
3598 A lot changes in the Makefile.ams around the irssi tree.
3600 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Do not rehash if the new size is same as the old size of the
3603 hash table, in the silc_hash_table_rehash*. The affected file
3604 lib/silcutil/silchashtable.c.
3606 * Replaced hash_table_del_by_context calls from the server
3607 (when channel->user_list and client->channels) to the
3608 hash_table_del as it is sufficient and faster.
3610 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Added silc_hash_table_list, silc_hash_table_get and the
3613 SilcHashTableList structure to provide an alternative way to
3614 traverse the hash table. The affected files are
3615 lib/silcutil/silchashtable.[ch].
3617 * Changed the server's idlist routines to use the hash table
3618 routines to optimize the code.
3620 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Replaced the client entry's `channel' list and channel entry's
3623 `user_list' list to hash tables for optimized lookup. Changed
3624 the code to use the hash table interface around the code.
3625 Affected file lib/silcd/idlist.[ch].
3627 * Added `auto_rehash' boolean argument to the function
3628 silc_hash_table_alloc to indicate whether the hash table should
3629 auto-rehash when it thinks is appropriate time. It will
3630 increase the hash table size if the there is twice as much
3631 entries in the table than the size of the table, and will
3632 decrease the size if there are twice as less entries than
3633 the size of the table.
3635 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3639 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * silc_idcache_purge_by_context deletes the entry now by context
3642 as it is supposed to do. Affected file lib/silccore/idcache.c.
3644 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3645 client is not anymore valid (WHOWAS givens the info) and not
3646 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3648 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Removed the `data' and `data_len' arguments from the ID Cache
3651 interfaces and added `name' argument. ID Cache does not handle
3652 anymore the binary data only a names associated with given ID.
3654 * When hashing a Client ID with silc_hash_id the entire ID is
3655 not hashed anymore, instead only the hash of the Client ID is
3656 hashed. This way we can access the Client ID from the cache
3657 with Client ID but with the hash of the ID (which is a hash of
3658 the nickname) as well without any difference in performance.
3660 Added also silc_idcache_find_by_id_one_ext to do one on one
3661 searching when we have the actual ID. Added also function
3662 silc_hash_client_id_compare. The affected files are
3663 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3665 * When hashing the name associated with a ID it is always done
3666 in lowercase. This way we can access the cache without worrying
3667 about case-sensitivity, even though, for example nicknames are
3670 * Fixed a bug in server with channel message sending. It put
3671 wrong ID type as destination ID. The affected file
3672 silcd/packet_send.c.
3674 * silc_idcache_del_by_context now deletes from all hash tables
3675 by context. Affected file lib/silccore/idcache.c.
3677 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Changed the client library to use the new ID Cache interface.
3680 Changes around the source tree.
3682 * Added silc_hash_table_rehash_ext to rehash with specific
3683 hash function. Affected file lib/silcutil/silchashtable.[ch].
3685 * Added silc_hash_string_compare to compare two strings in the
3686 hash table. Affected file lib/silcutil/silcutil.[ch].
3688 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Added new function silc_idcache_del_by_context into the
3691 lib/silccore/idcache.[ch].
3693 * Changed the server's ID list routines to use the new ID Cache
3694 interface. Changes around the source tree.
3696 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Added silc_hash_table_del[_by_context]_ext functions in to the
3699 lib/silcutil/silchashtable.[ch].
3701 Removed silc_hash_table_find_all* routines and added new
3702 silc_hash_table_find_foreach to replace them.
3704 Added silc_hash_table_replace_ext function as extended
3705 replacing function. Separated the simple hash table interface
3706 from the extended hash table interface in the file
3707 lib/silcutil/silchashtable.h.
3709 * Fixed minor bugs and changed it to use some of the new
3710 hash table functions in lib/silccore/idcache.c
3712 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Added new function silc_hash_table_find_all to return all keys
3715 in the hash table by the specified key. As the hash table is
3716 collision resistant it also makes it possible to have several
3717 duplicate keys in the hash table. This function may be used to
3718 find all of the keys from the hash.
3720 Added user_context arguments to the SilcHashFunction,
3721 SilcHashCompare and SilcHashDestructor to deliver user specified
3724 Added new fuctions silc_hash_table_find[_all]_ext to do
3725 extended lookup with specified hash and compare functions and
3726 specified user contexts.
3728 Added new function silc_hash_table_add_ext to add the key
3729 with specified hash function and user context.
3731 Added new function silc_hash_table_foreach to traverse all
3732 entrys in the hash table. Added SilcHashForeach callback
3735 Added new function silc_hash_table_del_by_context to delete
3736 the entry only if the context associated with the key matches.
3738 Affected files are lib/silcutil/silchashtable.[ch].
3740 * Removed silc_hash_[server/client/channel]_id and added just
3741 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3742 silc_hash_id_compare to compare two ID's using as the hash table
3743 comparison function. Added also silc_hash_data to hash
3744 binary data and silc_hash_data_compare to compare it.
3746 * Removed silc_idlist_find_client_by_hash as it is not needed
3747 anymore. Affected file silcd/idlist.[ch].
3749 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3750 to use internally the SilcHashTable. The new ID Cache is a lot
3751 faster than the old one. Some of the ID Cache interface was also
3752 rewritten and obsolete and stupid functions were removed.
3754 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Added entry_count field to the SilcHashTable to keep the number
3757 of the entries in the table. Implemented the function
3758 silc_hash_table_rehash. Added new function
3759 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3761 Fixed a minor bug in silc_hash_table_free.
3763 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3764 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3765 into the lib/silcutil/silcutil.[ch].
3767 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Implemented a collision resistant hash table into the
3770 lib/silcutil/silchashtable[ch]. See the header and the source
3771 for the SilcHashTable API.
3773 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Merged dotconf version 1.0.2 into lib/dotconf.
3777 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Do not compile anything in lib/silcsim/* if the SIM support
3780 is not enabled. The tree should now compile without problems
3783 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Compiled the SILC under cygwin. Compiled and tested briefly
3786 without problems. More tests needed. The SIMs didn't compile
3789 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3791 * Fixed possible crash in silc_get_username in the
3792 lib/silcutil/silcutil.c.
3794 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Fixed a va_arg in silc/client_ops.c.
3798 * Oops, RC5 routines were named AES and caused some problems
3799 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3801 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Added new SilcIDIP structure into the lib/silccore/id.h and
3804 replaced the old `ip' fields from all SILC ID's to that type.
3805 This is a step towards IPv6 support.
3807 The silc_id_get_len takes now the ID as an extra argument.
3808 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3809 both IPv4 and IPv6 based ID's.
3811 The affected files are lib/silccore/id.[ch] and other files
3812 around the tree using these routines.
3814 * Removed the ID length arguments in server from various
3815 silc_server_send_notify_* routines -> they are not needed
3818 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Fixed memory leak in silc_encode_pem_file in the file
3821 lib/silcutil/silcutil.c.
3823 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Check minor version as well in the SKE. Affected files are
3826 silcd/protocol.c and lib/silcclient/protocol.c.
3828 * Added --identifier option to the server so that an identifier
3829 can be when creating the public key for the server. Affected
3830 file is silcd/silcd.c.
3832 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3833 lib/silccrypt/silcpkcs.c.
3835 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Register default ciphers and stuff when using -C option with
3838 the server. Affected file sildc/silcd.c.
3840 * Put back the servers public key filename format, it is better
3841 than the new one. For now, the client keys are saved with the
3842 new filename format. The affected file silc/client_ops.c.
3844 * Implemented the Cipher API for the rest of the ciphers that
3845 did not implement it or implemented it the wrong way.
3847 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Register default ciphers and stuff when using the -S option
3850 in the client. Affected file silc/silc.c. Same also when
3851 creating new key pair with -C option.
3853 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Fixed the silc_verify_public_key client operation function to
3856 save the public keys differently. The fingerprint is now
3857 used as filename and not the hostname. This way also the
3858 client keys are saved uniquely and not with hostnames. The
3859 affected file is silc/client_ops.c.
3861 * Trimmed the silc_hash_fingerprint function to remove extra
3862 whitespaces from the end of the fingerprint. The affected
3863 file is lib/silccrypt/silchash.c.
3867 * Added silc_cipher_register_default function to register all
3868 default ciphers. It can be used when configuration files
3869 does not exist and the application does not want any specific
3870 ciphers in any specific order.
3872 The SilcDList is now used as silc_cipher_list dynamically
3873 allocated cipher list. Removed the static list all together
3874 and now all ciphers must be allocated to the dynamic list.
3875 The silc_cipher_alloc routine was changed to check only the
3878 All silc_cipher_* routines that used to return int returns
3881 The affected files lib/silccrypt/silccrypt.[ch].
3883 * The same thing was done to silc_hash_* as for silc_cipher_*
3884 routines. Affected files lib/silccrypt/silchash.[ch].
3886 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3887 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3888 Added also silc_pkcs_[un]register[_default] functions.
3889 Removed the data_context from the PKCS API.
3891 * Added silc_hmac_register_default function to register default
3892 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3893 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3894 to unregister all hmacs at once.
3896 * Register the default ciphers, hash functions, PKCSs and HMACs
3897 if client's configuration file does not exist. The affected
3900 * The client did not load the hash functions from the SIM
3901 modules at all. Added support for this. Affected file is
3902 silc/clientconfig.c.
3904 * When decoding public key with silc_pkcs_public_key_decode, check
3905 the supported algorithm only if PKCS are registered. Affected
3906 file lib/silccrypt/silcpkcs.c. The same was done with the
3907 silc_pkcs_private_key_decode.
3909 * Fixed the SILC List routines to keep the list always in order.
3910 It used to change the list's order when traversing the list but
3911 not it preserves the order. Affected file lib/trq/silclist.h.
3913 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Added the client library to use the SilcSocketConnection's
3916 reference counter (by silc_socket_dup) to prevent the bug that
3917 the socket object may be freed underneath async operation.
3919 * The name resolv library checking fixes in the configure.in.pre.
3922 * Created new version of the protocol drafts for future
3923 development. The -03 drafts are the ones that will be changed
3924 in the trunk now and the -02 will remain as they are.
3926 * Send list of CUMODE notifys to the router when announcing
3927 the channel users to the router. Affected file silcd/server.c.
3928 If the router receiving channel founder CUMODE for a channel
3929 that already has channel founder it will send CUMODE notify
3930 to the sender to remove the channel founder rights from the
3931 announced client. Affected file silcd/packet_receive.c.
3933 * The CUMODE notify may now use Server ID as well as the entity
3934 who changes the mode. Updated protocool specs.
3936 * Updated INSTALL and README files.
3938 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * New web pages in the http://silc.pspt.fi. The pages was
3945 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Implemented the [DenyConnectin] config section in the server.
3948 Added silc_server_config_denied_conn to check whether incoming
3949 connection is denied. Affected file silcd/serverconfig.[ch].
3951 * Do not check the ports when checking the incoming configuration
3952 data if the port is 0, meaning any. Affected file is
3953 silcd/serverconfig.c.
3955 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Fixed buffer overflow in silc_string_compare in the file
3958 lib/silcutil/silcutil.c.
3960 * Fixed double free in silc_server_command_leave in the file
3963 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Fixed the version checking in the server. Affected file is
3968 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Fixed the configuration data fetching when accepting new
3971 connections in the server. Affected file silcd/server.c.
3973 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Added `sender_entry' argument to the function
3976 silc_server_packet_relay_to_channel so that we can check
3977 whether some destination actually belongs to the same route
3978 the sender belongs (ie, we must not resend the packet to the
3979 sender). Affected file silcd/packet_send.[ch].
3981 * Added `servername' field to the SilcClientEntry in the server
3982 to hold the name of the server where client is from. Affected
3983 file is silcd/idlist.h.
3985 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Moved the channel message encrypting in the router betwen
3988 router connections from silc_server_channel_message to the
3989 silc_server_packet_relay_to_channel since we want to check
3990 whether we have anybody channel before encrypting anything.
3991 Affected files silcd/packet_[receive/send].c.
3993 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Fixed the [AdminConnection] server config section to support
3996 multiple entries. Affected file silcd/serverconfig.c.
3998 * Added support into the server to check the validity of the
3999 incoming connection before executing any KE or authentication
4002 * The connection configuration is now saved to the KE and
4003 connection auth protocol contexts and not fetched anymore in
4004 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4006 * The local hosts listenning address and port is also resolved
4007 now when starting the server. We want to have the socket object
4008 to include the real address and port for the listener. Added
4009 new function silc_net_check_local_by_sock into the files
4010 lib/silcutil/silcnet.[ch].
4012 * Fixed a broadcast bug in server -> do not broadcast if we
4015 * Fixed a routing bug. Do not route broadcast packets ever.
4016 Broadcast packets must be processed always and not routed since
4017 they may be destined to some other host than yourself and thus
4018 would get routed without no good reason. Affected file is
4021 * Added function silc_server_config_is_primary_route to check
4022 whether primary router connection has been configured (a router
4023 configuration that we are initiating). If there is not, we
4024 will assume that there is only two routers in the SILC network
4025 and we will use the incoming router connection as our primary
4026 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4028 * Changed the order of the broadcasting. Broadcast _after_ the
4029 packet has been processed not before. Affected file is
4032 * Fixed a [ClientConnection] parsing bug. The port was never
4033 parsed correctly thus resulting to port 0. Affected file
4034 silcd/serverconfig.c.
4036 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4037 argument and did not set the broadcast packet flag. Affected
4038 file silcd/packet_send.c. Fixed same bug in the function
4039 silc_server_send_notify as well.
4041 * If we receive NEW_ID packet for our own ID in the server, ignore
4044 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Removed the nickname from the Private Message Payload.
4049 Updated the code and the protocol specs.
4051 * Updated protocol specs for submitting to the IETF.
4053 * Tweaked the Random Number Generator a bit. Affected file
4054 lib/silccrypt/silcrng.c. Exported a new function
4055 silc_rng_[global]_add_noise which can be used to add more
4058 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Do not parse packets with different timeout when protocol
4061 is active -> may cause problem with rekey. Affected file
4064 * When server receives signoff notify it must not create
4065 new channel key if the client is on any channels since the
4066 sender of the signoff notify will create it.
4068 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Added printing of error messages during SKE protocol from the
4071 failure packet sent by server during SKE. Affected file
4074 * Removed the client's failure_callback handling with timeout
4075 and handle it immediately when received.
4077 * The SKE library returned wrong type in SUCCESS and FAILURE
4078 packets. They must be 32 bit MSB not 16 bit MSB.
4080 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Ok, rewrote the logic of the re-key and now it seems to work.
4083 I tested it on high traffic with frequent re-keys without
4084 problems. Added hmac_receive (and renamed hmac to hmac_send)
4085 in SilcClientConnection in lib/silcclient/client.h and
4086 in SilcIDListData in silcd/idlist.h. Also, removed the
4087 SilcPacketParserContext's cipher and hmac fields as they are
4088 not needed anymore and actually caused some problems when
4089 the ciphers and hmac's changed underneath the packet parser.
4091 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * If re-key protocol is active then process the incoming packets
4094 synchronously since we must assure that icoming packets encrypted
4095 with the old key is processed before the new keys is set to
4096 use. This is true other packets than for REKEY packets.
4097 Affected file silcd/server.c. The same was done to client library
4098 as well, affected file lib/silcclient/client.c.
4100 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Fixed bug in client and server to accept the force send if
4103 the packet is send from silc_[server/client]_packet_process
4104 function. Otherwise the packets are never delivered, oops.
4106 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Disable force sending of packets when REKEY protocol is active.
4109 We must assure that no packet is sent directly when rekey is
4110 performed. All packets must be sent through packet queue.
4111 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4112 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4113 function is silc_[server/client]_packet_send_real to check
4116 * Replaced the SIM paths from example config files to
4117 /usr/local/modules. Also, make install creates now
4118 /usr/local/silc/logs directory to hold all the SILC server
4121 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Made the configure.in.pre work on Solaris. Patch by salo.
4125 * Made all ciphers compatible with non-x86 machines. Defined
4126 CBC mode macros into lib/silccrypt/ciphers_def.h.
4128 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Fixed the make install.
4132 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * When MAC computation fails the silc_packet_decrypt returned 0
4135 even though it was supposed to return -1. Fixed this. The
4136 affected file is lib/silccore/silcpacket.c.
4138 * Do not replace the config files in /etc/silc (in make install)
4139 if they already exist. Affected file ./Makefile.am.
4141 * Do not send re-key packets immediately but through packet queue.
4142 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4144 * Changed silc_net_check_host_by_sock to return FALSE if the
4145 IP/DNS could not be resolved. Though, it returns the IP address
4146 now even if it could not resolve it (but returns also FALSE).
4147 Affected file lib/silcutil/silcnet.[ch].
4149 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Added silc_pkcs_decode_identifier to decode the public key's
4152 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4153 Added also silc_pkcs_free_identifier. Added also new context
4154 SilcPublicKeyIdentifier.
4156 * Added -S option to the silc client. It is used to dump the
4157 contents of the specified public key file.
4159 * Changed the PKCS api to return the public key length when
4160 setting the public key.
4162 * Fixed a fatal bug in the public and private key file loading.
4163 Affected file lib/silccrypt/silcpkcs.c.
4165 * Execute the packet parsing for client with zero (0) timeout
4166 if the protocol is active. Affected file silcd/server.c.
4168 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Made the key generation options to the silcd program. Added
4171 -C option, equivalent to client's option.
4173 * Added new [ServerKeys] config section to the server. It
4174 configures the server's public and private key.
4176 * Defined generic Public Key Payload into the protocol
4177 specification to send specific type of public keys and
4180 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4181 public key or certificate.
4183 * Implemented the GETKEY command to the server and to the
4184 client library and on user interface.
4186 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Made preliminary `make install' work.
4190 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Added SilcServerRekey context into silcd/idlist.h.
4194 * Added the PFS support as defined in the specification to the
4195 SKE protocol. Affected files lib/silcske/*.c.

4198 the number of the SKE group that is used with PFS in re-key.
4199 Affected file silcd/idlist.h.
4201 * Added PFS re-key support to the server. Affected file is
4204 * Added silc_protocol_cancel to cancel execution of the next
4205 state of the protocol. Affected file is
4206 lib/silccore/silcprotocol.[ch].
4208 * Added the re-key support with and without PFS to the client
4209 library. Re-key is performed once in an hour, by default.
4211 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4212 Added silc_client_rekey_callback and silc_client_rekey_final.
4213 Affected files are lib/silcclient/protocol.[ch] and

4216 * Removed the `hmac_key' and `hmac_key_len' fields from the
4217 SilcClientConnection structure; not needed. Affected file is
4218 lib/silcclient/client.h.
4222 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Do not ask whether user wants to use the negotiated private key
4225 for private messages, just use it. Affected file is
4226 silc/local_command.c.
4228 * Added `send_enc_key' and `enc_key_len' fields to the
4229 SilcIDListData structure since they are needed in the re-key
4230 phase. Affected file is silcd/idlist.[ch].
4232 * Implemented the simple re-key protocol into the server.

4244 the PFS is to be performed in the re-key. Affected file is
4247 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4250 int64 of at least the xintXX size. If void * is less that 4
4251 bytes uint32 * will be used. Defined bool as boolean.
4253 * Changed _ALL_ unsigned long and unsigned int to uint32,
4254 unsgined short to uint16 in the source tree.
4256 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4257 not handle clients that has entry->data.registered == FALSE.
4258 They are not in the network anymore. Affected file is
4261 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Implemented the sending of the SERVER_SIGNOFF notify in the
4264 server. Affected file is silcd/server.c.
4266 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4267 Added also silc_notify_payload_encode_args into the
4268 lib/silccore/silcnotify.[ch].
4270 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4271 Affected file silcd/packet_receive.c.
4273 * Implemented the SERVER_SIGNOFF notify handling in the client
4274 library. Affected file lib/silcclient/client_notify.c. Also,
4275 implemnted the printing of the SERVER_SIGNOFF info to the
4276 application. Affected file silc/client_ops.c.
4278 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4279 if the deleting was successful. Affected file silcd/idlist.[ch].
4281 * Added support for public key authentication in the connection
4282 authentication protocol in the client library. Affected file
4283 lib/silcclient/protocol.c.
4285 * Changed the server's silc_idlist_get_clients_by_* interface
4286 to support already allocated array so that new entries may be
4287 added to pre-allocated array. Affected file silcd/idlist.[ch].
4288 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4289 and command replies.
4291 * All command reply functions in the server now calls the
4292 pending command callback even if error occured. This way the
4293 error will be delivered to the client as well. Affected files
4294 silcd/command.c and silcd/command_reply.c.
4296 * Fixed INFO command to return local server's info if no server
4297 was provided. Affected file lib/silcclient/command.c.
4299 * Removed RESTART command for good. Updated the code and the
4302 * Rewrote parts of the task system. It is a bit simpler now.
4303 Removed unsued task priorities. The affected files are
4304 lib/silcutil/silctask.[ch].
4306 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Moved the USERS printing from the library to the application.
4309 Affected files lib/silcclient/command.c and silc/client_ops.c.
4311 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Added channel key re-key support. The re-key is perfomed
4316 only by the router and is done once in an hour. Added `rekey'
4317 field to the SilcChannelEntry in the server. Affected files
4318 silcd/server.c and silcd/idlist.h.
4320 * Added silc_task_unregister_by_context into the file
4321 lib/silcutil/silctask.[ch].
4323 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Added SILC_UMODE_GONE mode to indicate when the client is not
4326 present in the SILC network. Added also support to the local
4327 command AWAY that will set this mode. Added support of showing
4328 "xxx is gone" in WHOIS command. The USERS command shows the
4329 gone status as well.
4331 * Fixed setting server and router operator privileges in the
4332 server's UMODE command. Affected file silcd/command.c.
4334 * Merged the SKE KE1 and KE2 payloads into one payload. The
4335 new KE payload is equivalent to the old KE2 payload.
4337 Cleaned up the SKE Start Payload parsing. It now uses the
4338 simple buffer unformatting to do the parsing. A lot faster
4341 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4342 to the SKE that is used to indicate whether both of the SKE
4343 parties should perform authentication. By default only the
4344 responder performs authentication. By setting this flag also
4345 the initiator must do authentication. By default it is unset
4346 since in normal SKE case, client to server connection, only
4347 the responder should do authentication. When doing SKE between
4348 two clients both should perform authentication. Updated the
4349 code and the protocol specs.
4351 * A little fix to IDENTIFY command in the server. Search the
4352 client first by hash not nickname. Affected file is
4355 * Fixed the silc_client_close_connection to support closing
4356 the client to client connections wihtout deleting too much
4357 data. Affected file lib/silcclient/client.c.
4359 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4360 are received if protocol used to be active but is not anymore
4361 the application would crash due to NULL pointer dereference.
4362 Affected files silcd/server.c and lib/silcclient/client.c.
4364 * Added `hash' field to the SilcClientConnection to include
4365 the hash function negotiated in the SKE protocol.
4367 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4368 to set the channel founder authentication data. A client can
4369 claim the founder rights later by providing the authentication
4370 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4371 This way the channel founder can regain the channel founder
4372 privileges even it is left the channel. This works only on
4373 local server and the client must be connected to the same
4374 server to be able to regain the founder rights. Updated the
4375 protocol specs accordingly.
4377 Added support to the CMODE command in the client to set the
4378 founder auth data. Read the README to see how to set it.
4380 Added support to the CUMODE command to claim the founder
4381 rights. Read the README to see how to do it.
4383 Added support for the founder authentication to the Channel
4384 Entry in the server. Affected file silcd/idlist.h.
4386 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4387 server's CMODE command. Affected file silcd/command.c.
4389 * Added the following new functions into lib/silccore/silcauth.[ch]:
4390 silc_auth_get_method and silc_auth_get_data.
4392 * The server now saves the remote hosts public key to the
4393 SilcIDListData pointer. Affected file silcd/protocol.c.
4395 * The normal server now does not remove the channel entry from
4396 the cache if the founder authentication data is set. It used
4397 to remove it if the founder was the last one on the channel on
4398 the server and left the channel. The auth data is saved and
4399 if the channel is re-joined later the old entry is used with
4400 the old auth data. Affected files silcd/command_reply.c and
4403 * Removed the `pkcs' field from the SilcIDListData structure
4404 in the server; it is not used. Affected file silcd/idlist.h.
4406 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Fixed packet processing on slow links. Partial packets were
4409 never re-processed because the incoming data buffer was cleared
4410 by the application. Application must not directly clear the
4411 sock->inbuf, the packet processing routines handle it. Fixed
4412 this in client library and in server.
4414 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Fixed the WHOIS and IDENTIFY send reply function to really
4417 check whether to send list or just one entry. Affected file
4420 * Cleaned up the LEAVE command's channel key distribution. The
4421 affected file silcd/command.c.
4423 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4424 can enforce the channel mode as well. In that case the ID
4425 includes the ID of the server. The code now enforces the
4426 mode change if the router have different mode than the server.
4428 * The notify client operation with CMODE_CHANGE notify can now
4429 return NULL client_entry pointer if the CMODE was not changed
4430 by client. Application must check for this.
4432 * Added <Server ID> argument to INFO command to support server
4433 info fetching by Server ID.
4435 * Added silc_server_announce_get_channel_users to get assembled
4436 packets of channel users of the specified channel. Affected
4437 file silcd/server.[ch].
4439 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4440 was freed underneath the ID Cache.
4442 * Re-announce clients when the server received CHANNEL_CHANGE
4443 notify from the router. Affected file silcd/packet_send.c.
4445 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4448 crashed since it did not handle the fact that there is no cipher
4449 called "3" and didn't check the error condition. Now fixed.
4451 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4452 flag. It can be used to send message requests.
4454 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Implemented the RESTART command in the client.
4458 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4459 notice type messages. Added notice printing to the user
4462 * The channel keys are not re-generated if the channel's mode
4463 is PRIVKEY, ie private key on the channel exists. Affected
4464 files silcd/server.c and silcd/command.c.
4466 * Fixed a little bug in channel message delivery when channel
4467 private keys are set in the server. Affected file is
4468 silcd/packet_send.c.
4470 * Changed the setting on channel->on_channel = TRUE from the
4471 silc_client_save_channel_key to the JOIN command reply. The
4472 key payload is not received if the private channel key is set.
4473 Affected file lib/silcclient/command_reply.c and the
4474 lib/silcclient/client_channel.c.
4476 * When the CMODE_CHANGE notify is sent and the channel private
4477 key mode is removed the channel key must be re-generated in
4478 other cells as well. Added this support for the router in the
4479 silcd/packet_receive.c.
4481 * Added new local command NOTICE to send notice message on
4482 channel. Affected file silc/local_command.[ch].
4484 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Added new local command ME to the client. It is used to send
4487 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4488 some action. Affected file silc/local_command.[ch].
4490 * Changed channel_message and private_message client operations
4491 to deliver the message flags to the application. Added also
4492 the `flags' arguments to the silc_client_send_channel_message
4493 and silc_client_send_private_message functions. Affected file
4496 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Redefined the Private Message Payload to support private message
4499 keys and to support the new private message flags. Updated
4500 the protocol specs. Flags makes it possible to have for example
4501 CTCP style messages.
4503 * Added new type SilcPrivateMessagePayload and defined an API
4504 for it in the lib/silcclient/silcprivate.[ch].
4506 * Tested private message private keys successfully. Tested the
4507 private message key set, unset and list commands with the new
4510 * Redefined the Channel Message Payload to include the channel
4511 message flags (equal with private message flags) to support
4512 for example CTCP style messages.
4514 * Defined some of the message (for channel and private message)
4515 flags. Updated the protocol specs and added the flags to the
4516 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4518 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Added SilcKeyAgreementStatus type to the key agreement routines
4521 to indicate the current status and error if one occured.
4522 The status types are defined in the lib/silcclient/silcapi.h.
4524 * Added new local command KEY that is used to set and unset private
4525 keys for channels, set and unset private keys for private messages
4526 with remote clients and to send key agreement requests and
4527 negotiate the key agreement protocol with remote client. The
4528 key agreement is supported only to negotiate private message keys,
4529 it currently cannot be used to negotiate private keys for channels,
4530 as it is not convenient for that purpose.
4532 * Fixed a minor pending callback setting bug in the function
4533 silc_client_get_client_by_id_resolve, now the function works.
4534 Affected file lib/silcclient/idlist.c.
4536 * Added function silc_net_get_local_port to get local bound
4537 port by socket. Added to lib/silcutil/silcnet.[ch].
4539 * Added `sockets' and `sockets_count' fields to the SilcClient
4540 object. They hold the sockets of the listenning sockets in
4541 the client. Listenning sockets may be for example the key
4542 agreement server. Affected file lib/silcclient/client.[ch].
4543 Added functions the silc_client_add_socket and the
4544 silc_client_del_socket. They are exported to the application
4547 * Added ~./silc/clientkeys to support other client's public keys.
4549 * Renamed verify_server_key client operation to verify_public_key
4550 and added one argument to indicate the type of the connection
4551 (server, client etc.).
4553 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added silc_server_connection_auth_request to handle the
4556 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4557 silcd/packet_receive.[ch].
4559 * Added silc_server_send_connection_auth_request into the
4560 silcd/packet_send.c to send the connection auth request packet.
4562 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4565 * Fixed the public key authentication in responder side in the
4566 server. The `auth_data' pointer includes the SilcPublicKey
4567 not the path to the public key. Affected file silcd/protocol.c.
4569 * Implemented the public key authentication in the initiator side
4570 in the server. Affected file silcd/protocol.c.
4572 * Removed the [RedirectClient] config section from the server
4573 configuration. Is not needed and I don't want to implement it.
4575 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Cleaned up the CMODE command in the server. It now works
4578 correctly and supports all the modes defined in the protocol.
4579 Affected file is silcd/command.c.
4581 * Added `hmac_name' field to the SilcChannelEntry in the server
4582 to hold the default HMAC of the channel. It can be set when
4583 creating the channel (with JOIN command). Affected files
4586 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4587 type to indicate the change of the current cipher and hmac
4588 on the channel. Client can safely ignore the <cipher> argument
4589 (if it chooses to do so) since the CHANNEL_KEY packet will
4590 force the channel key change anyway. The <hmac> argument is
4591 important since the client is responsible of setting the new
4592 HMAC and the hmac key into use.
4594 * Fixed the CMODE command in the client library as well.
4596 * Tested CMODE command in router environment successfully.
4598 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Show the version of the remote client (or server) when connecting
4601 to the server. It is logged to the log file. Affected file
4602 is silcd/protocol.c.
4604 * Fixed the KILLED notify handling in the client library. The
4605 client must be removed from all channels when receiving the
4608 Also, do not remove the client entry when giving the KILL
4609 command but when the KILLED notify is received.
4611 * Removed silc_idlist_find_client_by_nickname from the server.
4612 Not needed anymore. Affected files silcd/idlist.[ch].
4614 * Implemented the CHANNEL_CHANGE notify type handling to the
4615 server. Affected file silcd/server.c.
4619 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Added silc_server_send_notify_invite to send the INVITE
4622 notify between routers.
4624 * Implemented the INVITE command correctly to the server.
4626 * Implemented the INVITE notify type handling in the server.
4628 * Implemented the INVITE command to the client library and on the
4631 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Added function silc_server_get_client_resolve to find the
4634 client entry by ID from all ID lists and then resolve it
4635 (using WHOIS) if it cannot be found. Affected file is
4638 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Implemented the BAN command to the client library.
4642 * The JOIN command in the server now checks the invite list
4645 * Changed the silc_command_reply_payload_encode_va and the
4646 silc_command_payload_encode_va to support that if argument is
4647 NULL it ignores and checks the next argument. Affected file
4648 lib/silccore/silccommand.c.
4650 * Added silc_server_send_notify_ban to send the BAN notify
4651 type between routers.
4653 * Chaned the silc_notify_payload_encode to support that if
4654 argument is NULL it ignores and checks the next argument.
4655 Affected file lib/silccore/silcnotify.c.
4657 * Tested ban lists in router environment successfully.
4659 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Implemented BAN command to the server, in silcd/command.[ch].
4663 * Removed the BAN and INVITE_LIST modes from the CMODE command
4666 * Added function silc_string_match to regex match two strings.
4667 Affected files lib/silcutil/silcutil.[ch].
4669 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Redefined parts of the SilcChannelEntry in the server to support
4672 the new ban and invite lists.
4674 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Redefined the INVITE command. The same command can be used to
4677 invite individuals to the channel but also to manage the invite
4678 list of the channel (to add to and remove from the invite list).
4679 Updated the protocol specs.
4681 * Added new command SILC_COMMAND_BAN that can be used to manage
4682 the ban list of the channel. Updated the protocol specs.
4684 * Removed the channel modes: the SILC_CMODE_BAN and the
4685 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4686 in the CMODE command. The equivalent features are now available
4687 using INVITE and BAN commands. Updated the protocol specs.
4689 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4690 in the network about change in the current ban list. The notify
4691 type is not used by the client.
4693 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4694 support the invite lists.
4696 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Added new function silc_string_regexify that converts string
4699 including wildcard characters into regex string that can
4700 be used by the GNU regex library. Added into the file
4701 lib/silcutil/silcutil.[ch].
4703 Added silc_string_regex_combine to combine to regex strings
4704 into one so that they can be used as one regex string by
4705 the GNU regex library. Added into the file
4706 lib/silcutil/silcutil.[ch].
4708 Added silc_string_regex_match to match two strings. It returns
4709 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4711 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * Imported GNU regex to the soruce tree into lib/contrib.
4714 Fixed some compiler warning from the regex.c.
4716 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Fixed MOTD command in the server to work in router environment.
4720 * Fixed the MOTD command in the client library to support
4721 the server argument in the command.
4723 * Added `nickname_len' argument to the silc_idlist_add_client
4724 in the server, as the `nickname' argument may be binary data
4727 * Added silc_idlist_get_channels to return all channels from
4730 * Implemented LIST command to the server. Affected file is
4733 * Implemented the LIST command to the client library and on the
4736 * Added [<user count>] argument to the LIST command reply.
4737 With private channels the user count is not shown.
4739 * Updated TODO and README.
4741 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * The client entry's data.registered must be TRUE even with
4744 global client entry on global client list. The data.registered
4745 is used to check whether the client is anymore in the network,
4746 for example with WHOWAS command so it must be valid.
4748 * Fixed the WHOWAS command in the server. It now actually works
4749 in router environment. Added function into silcd/command_reply.c
4750 silc_server_command_reply_whowas_save.
4752 * Added silc_idlist_purge function to the silcd/idlist.c
4753 to periodically purge the ID Cache.
4755 * Fixed INFO command in the server. It works now in router
4756 environment. Added <server name> argument to the INFO command
4757 reply. Updated the protocol specs.
4759 * Fixed minor bug in silc_idcache_purge to not purge if the
4760 expire value is zero.
4762 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4763 they were buggy because of the WHOWAS information.
4765 * Fixed local command MSG to handle the async resolving of
4766 the remote client properly. It used to fail the first MSG.
4767 Affected file silc/local_command.c.
4769 * Added `data_len' field to SilcIDCache context.
4771 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Update TODO. Todo in commands in the server.
4775 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4778 used by routers as broadcast packet to inform other routers
4779 about the changed user mode.
4781 Implemented the notify handling in the server. Affected file is
4782 silcd/packet_receive.c. Added the function
4783 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4785 * Added new generic Channel Payload and deprecated the New Channel
4786 Payload. The New Channel Payload is now the generic Channel
4789 * Added new argument `mode' to the silc_server_send_new_channel
4790 as it is required in the Channel Payload now.
4792 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4793 and created a new and real SilChannelPayload to represent the
4794 new generic Channel Payload. Implemented the encode/decode
4795 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4797 * Added silc_server_get_client_channel_list to return the list
4798 of channels the client has joined for WHOIS command reply.
4799 Affected file silcd/server.[ch].
4801 * Implemented the channel list sending in the WHOIS command reply
4802 in server and in the client.
4804 Implemented the channel list displaying on the user interface
4805 as well. Affected file silc/client_ops.c.
4807 * Added silc_channel_payload_parse_list to parse list of Channel
4808 Payloads. It returns SilcDList list of SilcChannelPayloads.
4809 Client for example can use this function to parse the list of
4810 channels it receives in the WHOIS command reply. The caller
4811 must free the list by calling silc_channel_payload_list_free.
4812 Affected files lib/silccore/silcchannel.[ch].
4814 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added one new argument <user mode> to the WHOIS command reply
4817 to return the mode of the user in SILC. Updated the protocol
4820 Implemented it to the server and client.
4822 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Fixed the mode printing on the user interface on joining.
4825 Affected file silc/client_ops.c.
4827 * Implemented the UMODE command and user modes in general to the
4828 client library and to the user interface.
4830 * Implemented the UMODE command to the server.
4832 * The server now sends UNKNOWN_COMMAND error status if client sends
4833 unknown command. Affected file silcd/command.c.
4835 * All server commands now handle the command identifier the right
4836 way when sending the command reply to the client. The client can
4837 use to identify the command replies with the identifier.
4839 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Added silc_server_get_client_route to resolve the route to
4842 the client indicated by the client ID. Affected file is
4845 * Added silc_server_relay_packet as general function to relay
4846 packet to arbitrary destination. This deprecates functions
4847 like _send_private_message_key, _relay_notify etc. Affected
4848 file is silcd/packet_send.[ch].
4850 Removed silc_server_send_key_agreement,
4851 silc_server_send_private_message_key and
4852 silc_server_packet_relay_notify functions from the file
4853 silcd/packet_send.[ch].
4857 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4858 server. Affected file silcd/packet_receive.[ch].
4860 * Implemented the KILL command to the client. Implemented the
4861 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4862 Affected files lib/silcclient/command[_reply].c and
4863 lib/silcclient/client_notify.c. Implemented the KILL notify
4864 printing in the user inteface.
4866 * Fixed a lot silc_parse_nick memory leaks from the client
4867 library in the file lib/silcclient/command.c.
4869 * Changed the silc_server_send_notify_on_channels's `sender'
4870 argument from SilcSocketConnection to SilcClientEntry to
4871 check the sender as entry and not as connection object and not
4872 to send to the client provided as argument. The affected file
4873 is silcd/packet_send.[ch].
4875 * The notify packets that are destined directly to the client used
4876 to not to be processed by the server. Now changed that and the
4877 server processes all notify packets. After relaying the packet
4878 to the client the notify packet is processed in the server.
4880 * The silc_server_free_client_data now checks whether there is
4881 pending outgoing traffic for the client and purges the data to
4882 the network before removing the client entry.
4884 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4887 an client is killed from the SILC Network. Updated the protocol
4890 Added new function silc_server_send_notify_killed to the
4891 silcd/packet_send.[ch].
4893 * Added function silc_server_packet_relay_notify to relay notify
4894 packets that are destined directly to a client. In this case
4895 the server does not process the notify packets but merely relays
4896 it to the client. Affected file silcd/packet_send.[ch].
4898 Added also silc_server_packet_process_relay_notify to check
4899 whereto relay the notify. Affected file is
4900 silcd/packet_receive.[ch].
4902 * Implemented the KILL command to the server.
4906 * Added the backup schema desgined last fall to the protocol
4907 specs for everyone to see. The specification is in the
4908 *-spec-xx.txt draft and the packet type definitions for the
4909 backup routers is in *-pp-xx.txt draft. Thusly, added also
4910 new packet type SILC_PACKET_CELL_ROUTERS.
4912 * A big security problem in the implementation discovered. The
4913 signoff of an client did not cause new channel key generation
4914 which it of course should've done. The channel keys must be
4915 always re-generated when client leaves (or signoffs) the channel.
4916 The silc_server_remove_from_channels funtion now handles
4917 the channel key re-generation.
4919 * Added `sender' argument to the silc_server_send_notify_on_channels
4920 to not to send the client provided as argument. Affected file
4921 silcd/packet_send.[ch].
4923 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Implemented OPER and SILCOPER commands into the server and
4928 * Added silc_auth_verify and silc_auth_verify_data to verify
4929 the authentication directly from the authentication payload.
4930 It supports verifying both passphrase and public key based
4931 authentication. Affected file lib/silccore/silcauth.[ch].
4933 * Added `hash' field to the SilcIDListData structure. It is the
4934 hash negotiated in the SKE protocol. Affected file is
4937 * Slight redesigning of the SilcAuthPayload handling routines.
4938 Do not send SilcPKCS but SilcPublicKey as argument.
4940 * Implemented the public key authentication support to the
4941 serverconfig. The public key is loaded from the provided path
4942 and saved as authentication data to void * pointer. Thus,
4943 changed the unsigned char *auth_data to void *auth_data;
4945 * Fixed SHUTDOWN command to send the reply before the server
4946 is shutdown. :) Affected file silcd/command.c.
4948 * Fixed fatal bug in CONNECT command. The hostname was invalid
4949 memory and server crashed. Affected file silcd/command.c.
4951 * Fixed fatal bug in CLOSE command. The server_entry became
4952 invalid but was referenced later in the command. Affected file
4955 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Fixed fatal bug in failure packet handling. Server ignored
4958 the failure and thus crashed when it came.
4962 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4965 that the command may be executed only once in (about) 2 seconds.
4966 The old SILC_CF_LAG flag is same but allows command bursts up
4967 to five before limiting.
4969 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4970 server code. Various commands now includes the CF_LAG_STRICT
4971 flag to disallow any kind of miss-use of the command.
4973 * Fixed the silc_buffer_unformat to not to allocate any data
4974 if the length of the data is zero. It used to allocate the
4975 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4977 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Changed the format of AdminConnection configuration section
4980 in the server. Added username of the admin to the format.
4981 Affected files silcd/serverconfig.[ch].
4983 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4984 to return admin configuration data by host, username and/or
4987 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Implemented WHOWAS command to the server. Added the functions:
4991 silc_server_command_whowas_parse,
4992 silc_server_command_whowas_send_reply,
4993 silc_server_command_whowas_from_client and
4994 silc_server_command_whowas_from_server
4996 * Added <Client ID> argument to the WHOWAS command reply. Updated
4997 the protocol specs accordingly.
4999 * Implemented WHOWAS command and command_reply to the client
5002 Implemented the WHOWAS printing on the user interface.
5004 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Added new argument to the WHOWAS command reply, the real name.
5007 It is an optional argument. Updated the protocol specs.
5009 * Added SilcIDCacheDestructor callback that is registered when
5010 the SilcIDCache is allocated. The callback is called when
5011 an cache entry in the ID Cache expires, or is purged from the
5012 cache. Added into lib/silccore/idcache.[ch].
5014 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5015 to destruct the client entries when the cache entry expires.
5016 Other ID Cache's in server and in the client library ignores
5019 * If the ID Cache entry's `expire' field is zero then the entry
5020 never expires. Added boolean `expire' argument to the
5021 silc_idcache_add function in the lib/silccore/idcache.[ch].
5022 If it is TRUE the default expiry value is used.
5024 * Added silc_server_free_client_data_timeout that is registered
5025 when client disconnects. By default for 5 minutes we preserve
5026 the client entry for history - for WHOWAS command.
5028 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added support to the server to enforce that commands are not
5031 executed more than once in 2 seconds. If server receives
5032 commands from client more frequently, timeout is registered
5033 to process the commands. Affected file silcd/command.c.
5034 Added new function silc_server_command_process_timeout.
5036 * Changed NICK_NOTIFY handling in client library to check that
5037 if the client's nickname was changed, so there is no need to
5038 resolve anything from the server.
5040 * Removed error printing from the WHOIS and IDENTIFY commands.
5041 If error occurs then it is ignored silently in the client library.
5042 The application, however, may map the received error to
5043 human readable error string. The application currently maps
5044 the NO_SUCH_NICKNAME error to string.
5046 * Made the command status message public to the application. Moved
5047 them from lib/silcclient/command_reply.c to
5048 lib/silcclient/command_reply.h. The application can map the
5049 received command status to the string with the
5050 silc_client_command_status_message function.
5052 * Added check to the server to check that client's ID is same
5053 as the Source ID in the packet the client sent. They must
5056 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added dist-bzip hook to the Makefile.am to make bzip2
5059 compressed distributions.
5061 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Server now enforces the maximum length for the nickname and
5064 the channel as protocol specification dictates. 128 bytes for
5065 nickname and 256 bytes for channel name.
5067 * Moved the WHOIS printing to the application. The client libary
5068 does not print out the WHOIS information anymore, the application
5069 must do it. Renamed silc_client_command_reply_whois_print to
5070 the silc_client_command_reply_whois_save.
5072 The client's idle time is also sent to the application now, and
5073 the idle is shown on screen.
5075 * Added silc_client_command_reply_identify_save to save the
5076 received IDENTIFY entries.
5078 * Do not check for channel private keys in message sending and
5079 reception if the channel does not have the PRIVKEY mode set.
5080 Affected file lib/silclient/client_channel.c.
5082 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5085 just surfaced after chaning the JOIN procedure.
5087 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Added silc_client_get_clients_by_list to get client entries
5090 from Client ID list, that is returned for example by JOIN
5091 and USERS command replies. The application should use this
5092 function for example when JOIN command reply is received to
5093 resolve the clients already on the channel (library does not
5094 do that anymore as USERS command reply is not used in the JOIN
5095 procedure anymore). Affected files lib/silcclient/silcapi.h and
5096 lib/silcclient/idlist.c.
5098 * JOIN command reply and USERS command reply returns now SilcBuffer
5099 pointers instead of unsigned char pointers when returning
5100 the client list and mode list.
5102 * Added <Client ID> argument to the JOIN command reply, mainly
5103 for the server to identify for which client the command was
5104 originally sent. Updated protocol specs accordingly.
5106 * Added SilcDlist private_key pointer to the SilcChannelEntry
5107 in the client to support the channel private keys. Affected
5108 file is lib/silcclient/idlist.h.
5110 * Added SilcChannelPrivateKey argument to the function
5111 silc_client_send_channel_message so that application can choose
5112 to use specific private ke if it wants to. If it is not provided,
5113 the normal channel key is used, unless private keys are set.
5114 In this case the first (key that was added first) is used
5115 as the encryption key.
5117 * Implemented the support for channel private key handling.
5118 Implemented the following functions:
5120 silc_client_add_channel_private_key,
5121 silc_client_del_channel_private_keys,
5122 silc_client_del_channel_private_key,
5123 silc_client_list_channel_private_keys and
5124 silc_client_free_channel_private_keys
5126 Affected file lib/silcclient/client_channel.c.
5128 * Added the support for the private keys in the channel message
5129 sending and encryption and in the message reception and
5130 decryption. Affected funtions are
5131 silc_client_send_channel_message and silc_client_channel_message.
5133 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added SKE's key verify callback to the client library's
5136 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5138 * Removed the statement that server (or router) must send USERS
5139 command reply when joining to the channel so that the client
5140 knows who are on the channel. Instead, the client list and
5141 client's mode list is now sent in the JOIN command reply to the
5142 client who joined channel. This is better solution.
5144 * Added function silc_server_get_users_on_channel and function
5145 silc_server_save_users_on_channel to the silcd/server.[ch].
5147 * Removed function silc_server_command_send_users from the
5150 * Do not show topic on the client library anymore. The topic is
5151 sent in the command reply notify to the application and the
5152 application must show the topic now.
5154 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Added client searching by nickname hash into the IDENTIFY and
5157 WHOIS commands in the server as they were clearly missing from
5158 them. Affected file is silcd/command.c.
5160 * Fixed a bug in private message receiving in the client library.
5161 The remote ID was freed and it wasn't supposed, now it is
5164 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Minor fix to the channel payload; allocate the data area, as it
5167 needs to be of specific length.
5169 * If the key agreement port is zero then the operating
5170 system will define the bound port. Affected files are
5171 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5173 * Added new function silc_channel_payload_decrypt into the file
5174 lib/silccore/silcchannel.[ch].
5176 * Moved the channel message etc, check from silc_packet_decrypt
5177 to applications. The library calls now a generic
5178 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5179 when the packet is either normal or special. This was done to
5180 allow more wide range of checking that was not allowed when
5181 the code was in library. Now applications can do virtually any
5182 checks to the packet and return to the library the decision how
5183 the packet should be processed. Affected files are
5184 lib/silccore/silcpacket.[ch].
5186 Added silc_server_packet_decrypt_check to the server and
5187 silc_client_packet_decrypt_check to the client library.
5189 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5190 to send with specified source and destination information.
5192 * Channel message delivery between routers was broken after the
5193 channel key distribution was fixed earlier. The channel key
5194 was used be to distributed to other routers as well which is not
5195 allowed by the protocol. Now this is fixed and channel keys
5196 really are cell specific and the channel message delivery between
5197 routers comply with the protocol specification.
5199 * Fixed various commands in server to check also the global list
5200 for the channel entry and not just the local list. The affected
5201 file silcd/command.c.
5203 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Added assert()s to buffer formatting and unformatting routines
5206 to assert (if --enable-debug) when error occurs. Affected
5207 file: lib/silcutil/silcbuffmt.c.
5209 * Changed to auto-reconnect to check whether the remote host is
5210 router and register the re-connect timeout if it is. It used
5211 to check that whether we are normal server, but router must do
5212 auto-reconnect with another router as well. Affected file
5215 * Removed the [<key len>] option from CMODE command as the cipher
5216 name decides the key length, nowadays. See the defined ciphers
5217 from the protocol specification.
5219 * Added [<hmac>] option to the CMODE command to define the HMAC
5220 for the channel. Added SILC_CMODE_HMAC channel mode.
5222 * Added [<hmac>] option for the JOIN command so that user can
5223 select which HMAC is used to compute the MACs of the channel
5226 * Added Hmac field to the Channel Message Payload. The integrity
5227 of plaintext channel messages are now protected by computing
5228 MAC of the message and attaching the MAC to the payload. The
5229 MAC is encrypted. Now, it is clear that this causes some
5230 overhead to the size of the packet but rationale for this is that
5231 now the receiver can verify whether the channel message decrypted
5232 correctly and also when private keys are set for the channel the
5233 receiver can decrypt the packet with several keys and check from
5234 the MAC which key decrypted the message correctly.
5236 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5237 lib/silccrypt/silccipher.[ch].
5239 * Added silc_hash_len to return the digest length into the
5240 lib/silcrypt/silchash.[ch].
5242 * Rewrote parts of Silc Channel Payload interface in the
5243 lib/silccore/silcchannel.[ch]. The encode function now also
5244 encrypts the packet and parse function decrypts it.
5246 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Fixed a minor formatting bug in the SKE's key material processing.
5249 It actually might have processed the keys wrong way resulting
5252 * Redefined the mandatory HMAC algorithms and added new algorithms.
5253 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5254 and hmac-md5 truncated to 96 bits. The mandatory is now
5255 hmac-sha1-96. Rest are optional (including the one that used
5256 to be mandatory). Rationale for this is that the truncated HMAC
5257 length is sufficient from security point of view and can actually
5258 make the attack against the HMAC harder. Also, the truncated
5259 HMAC causes less overhead to the packets. See the RFC2104 for
5262 * Added new [hmac] configuration section. The SKE used to use
5263 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5264 is of course wrong. The official names that must be proposed in
5265 the SKE are the ones defined in the protocol specification
5266 (hmac-sha1-96 for example). The user can configure any hmac
5267 using any hash function configured in the [hash] section. At
5268 least, the mandatory must be configured.
5270 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5272 * Added HMAC list to the SKE proposal list. It has now both
5273 hash algorithm list and HMAC list. This makes the protocol
5274 incompatible with previous versions. The SKE now seems to work
5275 the way it is supposed to work, for the first time actually.
5277 * Defined plain Hash algorithms to the protocol specification.
5280 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Implemented support for key agreement packets into the server.
5283 Added functions silc_server_key_agreement and
5284 silc_server_send_key_agreement. Other than these functions,
5285 server has nothing to do with this packet.
5287 * Added support for private message key packets into the server.
5288 Added functions silc_server_private_message_key and
5289 silc_server_send_private_message_key.
5293 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5294 called in the protocol's final callback instead in the END
5295 protocol state. This makes a little more sense and in the same
5296 time in client we can use the same protocol routines for normal
5297 key exchange and to key agreement packet handling as well.
5299 * Added to both client's and server's KE protocol context the
5300 SilcSKEKeyMaterial pointer to save the key material. We will
5301 bring the key material to the protocol's final callback by doing
5302 this. The final callback must free the key material.
5304 * Added SKE's packet_send callback into client's KE protocol
5305 context so that the caller can choose what packet sending function
5306 is used. This way we can use different packet sending when
5307 doing normal SKE when doing key agreement packet handling (in
5308 the key agreement packet handling we do not want to encrypt
5311 * Implemented the responder side of the key agreement routines
5312 in the client. The client can now bind to specified port and
5313 accept incoming key negotiation. The key material is passed
5314 to the application after the protocol is over.
5316 * Implemented the processing of incoming Key Agreement packet
5317 in the client. Added function silc_client_key_agreement to
5320 * Implemented the intiator side of the key agreement routines
5321 in the client. The client can now initiate key agreement with
5322 another remote client. The key material is passed to the
5323 application after the protocol is over.
5325 * Created client_keyagr.c to include all the key agreement
5328 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5329 SILC_TASK_CALLBACK except that it is not static.
5331 * Created client_notify.c and moved the Notify packet handling
5332 from the client.[ch] into that file.
5334 * Created client_prvmsg.c and moved all private message and
5335 private message key routines from the client.[ch] into that file.
5337 * Create client_channel.c and moved all channel message and
5338 channel private key routines from the client.[ch] into that file.
5340 * Changed silc_client_get_client_by_id_resolve to resolve with
5341 WHOIS command instead of IDENTIFY command, in the file
5342 lib/silclient/idlist.c.
5344 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Implemented the SKE's responder side to the Client library.
5348 * When FAILURE is received to the protocol do not trust it
5349 blindly. Register a timeout to wait whether the remote closes
5350 the connection as it should do it, only after that process the
5351 actual failure. This was changed to both client and server.
5353 * Added client_internal.h to include some of the structures
5354 there instead of client.h in lib/silcclient/.
5356 * Added function silc_task_unregister_by_callback to unregister
5357 timeouts by the callback function.
5359 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Some "Incomplete WHOIS info" errors has been appearing on the
5362 log files. Took away the entry->userinfo check from WHOIS
5363 reply sending. The entry->userinfo is now " " if client did not
5364 provide one. I thought this was fixed earlier but something
5365 is wrong still. Let's see if the error still appears.
5367 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Fixed a minor bug in the login when the channel key is
5370 re-generated in the server. It used to generate the key in
5371 wrong order and thus caused problems in the channel traffic.
5373 * Fixed a minor bug in channel key distsribution after
5374 KICK command. The key was not sent to the router even though
5377 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Added silc_ske_process_key_material_data as generic routine
5380 to process any key material as the SILC protocol dictates. The
5381 function is used by the actual SKE library but can be used by
5382 applications as well. This relates to the private message keys
5383 and the channel private keys since they must be processed the
5384 same way the normal SILC session keys. The protocol dictates
5385 this. Affected files: lib/silcske/silcske.[ch].
5387 Added also silc_ske_free_key_material to free the
5388 SilcSKEKeyMaterial structure.
5390 * Defined silc_cipher_set_key function to set the key for
5391 cipher without using the object's method function. The affected
5392 files: lib/silccrypt/silccipher.[ch].
5394 * Implemented silc silc_client_add_private_message_key,
5395 silc_client_add_private_message_key_ske,
5396 silc_client_del_private_message_key,
5397 silc_client_list_private_message_keys and
5398 silc_client_free_private_message_keys functions in the
5401 Added functions silc_client_send_private_message_key to send
5402 the Private Message Key payload and silc_client_private_message_key
5403 to handle incoming Private Message Key payload.
5405 * Added Cipher field to the Private Message Key payload to set
5406 the cipher to be used. If ignored, the default cipher defined
5407 in the SILC protocol (aes-256-cbc) is used.
5409 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Removed lib/silcclient/ops.h file.
5413 Redefined parts of the SILC Client Library API. Created new
5414 file silcapi.h that deprecates the ops.h file and defines the
5415 published Client Library API. Defined also private message key
5416 API and channel private key API into the file.
5418 This is the file that the application must include from the
5419 SILC Client Library. Other files need not be included by
5420 the application anymore.
5422 * Added new key_agreement client operation callback and also
5423 defined the Key Agreement library API for the application.
5425 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5428 is used by clients to request key negotiation between another
5429 client in the SILC network. If the negotiation is started it
5430 is performed using the SKE protocol. The result of the
5431 negotiation, the secret key material, can be used for example
5432 as private message key.
5434 Implemented the Key Agreement payload into the files
5435 lib/silccore/silauth.[ch].
5437 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Redefined ciphers for the SILC protocol. Added some new ciphers
5440 and defined the key lengths for the algorithms. Changed the
5441 code accordingly. The default key length is now 256 bits.
5443 * Fixed SKE key distribution function silc_ske_process_key_material
5444 when the key length is more than 128 bits. The default key
5445 length in SILC is now 256 bits.
5447 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5448 to indicate unsupported algorithm.
5450 * Renamed rijndael.c to aes.c and all functions as well.
5452 * Fixed a long standing channel key setting bug in client library.
5453 Weird that it has never surfaced before.
5455 * Fixed bug in channel deletion. If the entire channel is removed
5456 then it must also delete the references of the channel entry
5457 from the client's channel list as the client's channel entry and
5458 the channel's client entry share same memory.
5460 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Implemented CONNECT and SHUTDOWN commands in the client.
5464 * Implemented CLOSE command to the client.
5466 * Added the function silc_idlist_find_server_by_name into the
5467 files silcd/idlist.[ch].
5469 Added the function silc_idlist_find_server_by_conn into the
5470 files silcd/idlist.[ch].
5472 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * DIE command was renamed to SHUTDOWN. Updated the both code
5477 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5478 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5480 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5483 * Added function silc_server_create_connection function to create
5484 connection to remote router. My server implementation actually
5485 does not allow router to connect to normal server (it expects
5486 that normal server always initiates the connection to the router)
5487 so the CONNECT command is only good for connecting to another
5490 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5493 or some other client was kicked from the channel.
5495 Implemented the handling of the notify type to both client
5498 Implemented silc_server_send_notify_kicked to send the KICKED
5499 notify. It is used to send it to the server's primary router.
5501 * Implemented the KICK command into server and client.
5503 * Added `query' argument to the silc_idlist_get_client function
5504 to indicate whether to query the client from server or not if
5507 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5508 to indicate that the client is not channel founder.
5512 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Removed the rng context from SilcPacketContext structure and
5515 changed that the packet routine uses the Global RNG API.
5517 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added support for quit message that client can "leave" on the
5520 channel when it quits the SILC. It is ditributed inside the
5521 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5523 Added silc_server_free_client_data that will take the
5524 signoff message as argument.
5526 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5528 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Updated parts of the protocol specification to keep it up
5533 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5536 payloads in one packet.
5538 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5539 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5540 use now the new List flag.
5542 * Also deprecated the following packet types: REPLACE_ID,
5543 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5545 * Added list support for Notify packet in server.
5547 * Added silc_server_send_notify_channel_change to send the
5548 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5549 the silc_server_send_replace_id.
5551 * Added silc_server_send_notify_nick_change to send the
5552 NICK_CHANGE notify type. Deprecates the function
5553 silc_server_send_replace_id.
5555 * Added silc_server_send_notify_join to send the JOIN notify type.
5556 Deprecates the function silc_server_send_new_channel_user.
5558 * Added silc_server_send_notify_leave to send LEAVE notify type.
5559 Deprecates the function silc_server_send_remove_channel_user.
5561 * Added silc_server_send_notify_cmode and
5562 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5563 types. Deprecates the silc_server_send_set_mode function.
5565 * Added SERVER_SIGNOFF notify type to indicate that server has
5566 quit. This means that all clients on the channel from that
5567 server will drop. This can be also used when netsplit happens.
5569 Deprecated REMOVE_ID packet type since it is not needed anymore
5572 Added silc_server_send_notify_server_signoff to send the
5573 SERVER_SIGNOFF notify type. Deprecates the function
5574 silc_server_send_remove_id.
5576 Added also silc_server_send_notify_signoff to send the
5577 SIGNOFF notify type.
5579 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5580 SILC protocol from this day on. Changed the protocol
5581 specification as well.
5583 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5584 notify type. It is used between routers to notify about
5585 topic changes on a channel.
5587 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5590 * Partly updated the protocol specification to comply with the
5591 changes now made. It is still though a bit outdated.
5593 * The JOIN notify type now takes one extra argument <Channel ID>.
5594 The packet used to be destined to the channel but now the
5595 JOIN type may be sent as list thus it is impossible to
5596 destine it to any specific channel. By adding this argument
5597 it is again possible.
5599 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Added CREDITS file. The CHANGES and CREDITS file will appear
5602 in the distribution as well.
5604 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5607 types in the server's silcd/packet_receive.c.
5609 * Implemented CMODE and CUMODE to work in router environment.
5611 * Fixed minor encoding and decoding buglet from the
5612 lib/silccore/silcmode.c.
5614 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5617 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5619 * Changed all SilcConfigServer* and silc_config_server* to
5620 SilcServerConfig* and silc_server_config*, respectively.
5623 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Associated the ID (client or server ID) to the Authentication
5626 Payload to avoid any possibility of forging. Updated the
5627 protocol specification and the code accordingly.
5629 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * The RSA key length is now save to the RsaKey context in the
5632 key generation process in lib/silccrypt/rsa.c. The key length
5633 is now used to figure out the maximum size of the block allowed
5634 to be encrypted/signed.
5636 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5637 is equivalent to the silc_mp_mp2bin but does not allocate any
5640 * Changed silc_mp_mp2bin API to take length argument. If it is
5641 non-zero then the buffer is allocated that large. If zero, then
5642 the size is approximated using silc_mp_sizeinbase, which however
5645 * Created Global RNG API which is global RNG that application can
5646 initialize. After initializing, any routine anywhere in the
5647 code (including library) can use RNG without allocating a new
5648 RNG object. This was done to allow this sort of use of the
5649 RNG in code that has no chance to allocate RNG object. All
5650 applications currently allocate this and many routines in the
5651 library use this. Affected file lib/silccrypt/silcrng.[ch].
5653 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5654 it to use the Global RNG API.
5656 * Defined Authentication Payload into protocol specification that
5657 is used during SILC session to authenticate entities. It is
5658 used for example by client to authenticate itself to the server
5659 to obtain server operator privileges.
5661 Implemented this payload into the lib/silccore/silcauth.[ch].
5662 Implemented also routines for public key based authentication
5663 as the new protocol specification dictates.
5665 Moved definitions of different authentication methods from
5666 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5668 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5669 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5670 silc_pkcs_verify_with_hash functions into the file
5671 lib/silccrypt/silcpkcs.[ch].
5673 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * The client entry's userinfo pointer must be always valid.
5676 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5677 will fail since it requires the userinfo. Now, the userinfo
5678 is allocated as "" if actual userinfo does not exist. Actually,
5679 it must exist and it is totally Ok to drop client connections
5680 that does not announce the userinfo. However, we will make
5681 this workaround for now.
5683 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5684 to return the remote port by socket.
5686 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5689 SILC_SERVER_PENDING_EXEC and added an new macro
5690 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5691 data or when error occurs while processing the pending command.
5693 Added new argument `destructor' into silc_server_command_pending
5694 and to the SilcServerCommandPending object. This destructor is
5695 now called after calling the pending callback or if error occurs
5696 immediately. If error occurs the actual pending callback won't
5697 be called at all - only the destructor. The destructor may be
5698 NULL if destructor is not needed.
5700 All this applies for client library code as well. Similar
5701 changes were made there as well for the pending commands.
5703 In the client, the application must now allocate the
5704 SilcClientCommandContext with the silc_client_command_alloc
5707 * Added reference counter to the SilcServerCommandContext. Added
5708 function silc_server_command_alloc and silc_server_command_dup
5711 Same type of functions added to the client library for the same
5714 * Removed the cmd_ident from IDListData away since it is now
5715 global for all connections. It is the command identifier used
5716 in command sending and with pending commands. The affected file
5719 * Added reference counter to the SilcSocketConnection objecet to
5720 indicate the usage count of the object. The object won't be
5721 freed untill the reference counter hits zero. Currently only
5722 server uses this, and client ignores it. The client must be
5723 set to use this too later. The affected files are
5724 lib/silccore/silcsockconn.[ch]. Added also the function
5725 silc_socket_dup to increase the reference counter.
5727 This was mainly added because it is possible that the socket
5728 is removed underneath of pending command or other async
5729 operation. Now it won't be free'd and proper DISCONNECTING
5730 flags, etc. can be set to avoid sending data to connection that
5731 is not valid anymore.
5733 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5734 the connection. After that it sets SILC_SET_DISCONNECTED.
5735 It is, however, possible that the socket data is not still freed.
5736 The silc_server_packet_process now checks that data is not
5737 read or written to connection that is DISCONNECTED. The socket
5738 get's freed when the reference counter hits zero.
5740 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Changed the client operation API: channel_message operation's
5743 `sender' is now the client entry of the sender, not the nickname
5744 and the `channel' is the channel entry, not the channel name.
5746 In the private_message operation the `sender' is now also the
5747 client entry of the sender not the nickname.
5749 Affected file is lib/silcclient/ops.h and all applications
5750 using the client operations.
5752 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Moved the calling of ops->connect() from connect_to_server_final
5755 into receive_new_id functin since that is the point when the
5756 client is actually allowed to send traffic to network. The
5757 affected file is lib/silcclient/client.c.
5759 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5762 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5763 (if needs broadcasting) instead of broadcasting the packets one
5764 by one which would make a burst in the network traffic.
5766 * Added `broadcast' argument to the functions in silcd/server.[ch]
5767 silc_server_create_new_channel[_with_id] to indicate whether
5768 to send New Channel packet to primary router.
5770 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Added new function into the silcd/server.[ch] files:
5773 silc_server_create_new_channel_with_id to create new channel with
5774 already existing Channel ID.
5776 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5777 lib/silccore/silcpacket.h. This packet is used t send list of
5778 Set Mode payloads inside one packet. Server uses this to set
5779 the modes for the channels and clients on those channels, that it
5780 announced to the router when it connected to it. The protocol
5781 specification has been updated accordingly.
5783 * The silc_server_new_channel did not handle the packet coming
5784 from normal server as it normally does not send that. However,
5785 when it announces its channels it does send it. Implemented
5786 the support for that.
5788 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5789 into the file lib/silccore/id.h.
5791 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Fixed memory leaks in the functions silc_idlist_del_client,
5794 silc_idlist_del_channel and silc_idlist_del_server in the file
5795 silcd/idlist.c. All of those leaked like a sieve.
5797 * Fixed some small memory leaks in the client's function
5798 silc_client_notify_by_server.
5800 * Added functions into silcd/server.c: silc_server_announce_clients,
5801 silc_server_announce_channels and silc_server_announce_server.
5802 These functions are used by normal and router server to announce
5803 to its primary router about clients, channels and servers (when
5804 router) that we own. This is done after we've connected to the
5807 These functions effectively implements the following packet types:
5808 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5809 and SILC_PACKET_NEW_ID_LIST.
5811 * Added new functions into the silcd/packet_receive.[ch]:
5812 silc_server_new_id_list, silc_server_new_channel_list and
5813 silc_server_new_channel_user_list to handle the incoming
5814 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5816 * Added support of changing Channel ID in the function
5817 silc_server_replace_id. If the server that announces a channel
5818 to the router already exists in the router (with same name but
5819 with different Channel ID), router is responsible to send
5820 Replace ID packet to the server and force the server to change
5821 the Channel ID to the one router has.
5823 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5824 client that the Channel ID has been changed by the router. The
5825 normal server sends this to the client. Client must start using
5826 the new Channel ID as the channel's ID.
5828 Implemented handling of this new type into lib/silcclient/client.c
5829 into the function silc_client_notify_by_server.
5831 * Added new function silc_idlist_replace_channel_id into the files
5832 silcd/idlist.[ch] to replace the Channel ID.
5834 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Call silc_server_command_identify_check always when processing
5837 the IDENTIFY command in silcd/command.c
5839 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5842 send keepalive packets. The packet can be sent by clients,
5843 servers and routers.
5845 Added function silc_socket_set_heartbeat into the file
5846 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5847 If not set, the heartbeat is not performed. The actual
5848 heartbeat is implemented in the low level socket connection
5849 library. However, application is responsible of actually
5852 Added silc_server_send_heartbeat to send the actual heartbeat
5853 packet into silcd/packet_send.[ch]. Server now performs
5854 keepalive with all connections.
5856 * Added silc_task_get_first function into lib/silcutil/silctask.c
5857 to return the timeout task with shortest timeout. There was a bug
5858 in task unregistration that caused problems. TODO has been
5859 updated to include that task system must be rewritten.
5861 * The client library will now resolve the client information when
5862 receiving JOIN notify from server for client that we know but
5863 have incomplete information.
5865 * Rewrote parts of silc_server_remove_from_channels and
5866 silc_server_remove_from_one_channel as they did not remove the
5867 channel in some circumstances even though they should've.
5869 * Encryption problem encountered in server:
5871 The LEAVE command used to send the Channel Key packet to the
5872 router immediately after generating it. However, the code
5873 had earlier sent Remove Channel user packet but not immediately,
5874 ie. it was put to queue. The order of packets in the router
5875 was that Channel Key packet was first and Remove Channel User
5876 packet was second, even though they were encrypted in the
5877 reverse order. For this reason, MAC check failed. Now, this
5878 is fixed by not sending the Channel Key packet immediately but
5879 putting it to queue. However, this is more fundamental problem:
5880 packets that are in queue should actually not be encrypted
5881 because packets that are sent immediately gets encrypted
5882 actually with wrong IV (and thus MAC check fails). So, packets
5883 that are in queue should be encrypted when they are sent to
5884 the wire and not when they put to the queue.
5886 However, the problem is that the current system has not been
5887 designed to work that way. Instead, the packet is encrypted
5888 as soon as possible and left to the queue. The queue is then
5889 just purged into wire. There won't be any fixes for this
5890 any time soon. So, the current semantic for packet sending
5893 o If you send packet to remote host and do not force the send
5894 (the packet will be in queue) then all subsequent packets to the
5895 same remote host must also be put to the queue. Only after the
5896 queue has been purged is it safe again to force the packet
5899 o If you send all packets immediately then it safe to send
5900 any of subsequent packets through the queue, however, after
5901 the first packet is put to queue then any subsequent packets
5902 must also be put to the queue.
5904 Follow these rules and everything works fine.
5906 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Added new function silc_server_remove_clients_by_server to
5909 remove all client entries from ID list when the server connection
5910 is lost. In this case it is also important to invalidate all
5911 client entires as they hold the invalid server entry. This
5912 fixes fatal bug when server has lost connection and will reconnect
5915 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Made some sanity checks to silc_server_daemonise like to check
5918 whether the requested user and group actually exists.
5920 * Added sanity check to SKE's silc_ske_responder_finish to check
5921 that the public and private key actually is valid.
5923 * Invalidate the client's nickname when receiving Replace ID
5924 packet and the Client ID is being replaced. This means that the
5925 server will query the nickname if someone needs it (client)
5928 * Sort the ID Cache in client library when the ID Cache data
5929 has changed (needs sorting).
5931 * Do not allow for SILC client to create several connections to
5932 several servers. The client does not support windows right now
5933 and generating multiple connections causes weird behaviour.
5935 Irssi-silc client does support windows and can handle several
5936 connections without problems, see: www.irssi.org and SILC plugin.
5938 * Fixed some places where client was added to the IDList. The
5939 rule of thumb is following (in order to get everything right):
5940 If the client is directly connected local client then the
5941 `connection' argument must be set and `router' argument must be
5942 NULL to silc_idlist_add_client function. If the client is not
5943 directly connected client then the `router' argument must
5944 bet set and the `connection' argument must be NULL to the
5945 silc_idlist_add_client function.
5947 * The funtion silc_server_packet_send_local_channel actually did
5948 not check whether the client was locally connected or not. It
5949 does that now. Fixed a bug related to LEAVE command.
5951 * Fixed Remove Channel User payload parsing bug in server's
5952 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5954 * The server's silc_server_save_channel_key now checks also the
5955 global ID list for the channel as it might not be in the local
5956 list. Fixed a bug related to LEAVE command.
5958 * Is this the end of the [<unknown>] buglet that has been lurking
5959 around for a long time? A little for loop fix in server's
5960 silc_server_command_whois_parse that is used by both IDENTIFY
5961 and WHOIS command. At least, this was a clear bug and a cause
5962 of one type of [<unknown>] buglet.
5964 * WHOIS and IDENTIFY commands call the function
5965 silc_server_command_[whois/identify]_check function even if
5966 we are not router server.
5968 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Added --with-gmp configuration option. If set the GMP
5971 is always compiled in the SILC source tree. If not set then
5972 it is checked whether the system has the GMP3 installed. If
5973 it has then the GMP won't be compiled (the system's headers
5974 and library is used), if it doesn't have it then the GMP is
5975 compiled in the SILC source tree.
5977 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Changed RSA private exponent generation to what PKCS #1
5980 suggests. We try to find the smallest possible d by doing
5981 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5982 not security fix but optimization.
5984 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Added new config entry [Identity] to fork the server and run
5987 it as specific user and group. A patch from Bostik.
5989 * Imported Dotconf configuration library into lib/dotconf.
5990 This will be used to create the SILC configuration files later.
5991 It will appear in the distsribution after this commit.
5993 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * A big code auditing weekend happening. Auditing code for
5996 obvious mistakes, bugs and errors. Also, removing any code
5999 Removed files for being obsolete:
6001 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6002 inline in the file lib/silcutil/silcbuffer.h)
6004 o lib/silcutil/silcbufutil.c (the header has inline versions)
6006 Changed code to fix possible error conditions:
6008 o The buffer formatting routines now check that the destination
6009 buffer really has enough space to add the data. This applies for
6010 both buffer formatting and unformatting
6011 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6012 unformatting was changed to accomodate following rules:
6013 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6014 sent to the function while XXX_*STRING will not allocate or copy
6015 the data into the buffer. Instead it sets the pointer from the
6016 buffer into the pointer sent as argument (XXX_*STRING used to
6017 require that the pointer must be allocated already). This change
6018 makes this whole thing a bit more consistent and more optimized
6019 (note that the data returned in the unformatting with XXX_*STRING
6020 must not be freed now). The routines return now -1 on error.
6022 o Tried to find all code that use buffer_format and buffer_unformat
6023 and added return value checking to prevent formatting and
6024 especially unformatting errors and possible subsequent fatal
6027 o Changed ske->x and ske->KEY to mallocated pointers in
6028 lib/silcske/silcske.h. Fixed possible data and memory leak.
6030 o Added return value checking to all *_parse* functions. Fixed
6031 many memory leaks as well.
6033 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6034 so that buffer overflows would not happen. All code now also
6035 checks the return value as it can fail.
6037 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Added reconnection support to server if the normal server looses
6040 its connection to the router (for example if router is rebooted).
6041 The server performs normal reconnection strategy implemented
6042 to the server. Affected file silcd/server.c.
6044 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added new packet type SILC_PACKET_SET_MODE that is used to
6047 distribute the information about changed modes (for clients,
6048 channels and clients channel modes) to all routers in the
6049 network. Updated the protocol specification accordingly.
6051 Added functions into silcd/packet_send.c and
6052 silcd/packet_receive.c: silc_server_send_set_mode,
6053 silc_server_set_mode.
6055 Added new files silcmode.[ch] into lib/silccore that implements
6056 the encoding and decoding of Set Mode Payload. Added new type
6057 SilcSetModePayload. Moved the definitions of different modes
6058 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6060 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Oops, a little mistake in server's connection authentication
6063 protocol. The protocol is not ended with FAILURE but with
6064 SUCCESS if the authentication is Ok. :) Affected file is
6067 * Implemented NICK_CHANGE notify handling in server in the file
6068 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6069 the local clients on the channel. After the changing nickname
6070 in router environment snhould work and the [<unknown>] nickname
6071 should appear no more.
6073 The silc_server_replace_id function that receives the Replace ID
6074 payload now sends the NICK_CHANGE notify type also in the file
6075 silcd/packet_receive.c
6077 * Changed WHOIS and IDENTIFY command to support the maximum amount
6078 of arguments defined in protocol specs (3328 arguments). This
6079 fixed a bug that caused problems when there were more than three
6082 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Added extra parameter, command identifier, to the
6085 silc_client_send_command so that explicit command identifier
6088 Changed that ID list routines uses specific command identifier
6089 when sending WHOIS/IDENTIFY requests to the server so that they
6090 can be identified when the reply comes back.
6092 Affected files lib/silcclient/command.[ch],
6093 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6095 * Added `sender' argument to silc_server_packet_send_to_channel
6096 to indicaet the sender who originally sent the packet to us
6097 that we are now re-sending. Ignored if NULL. Affected file
6098 silcd/packet_send.[ch].
6100 * Added some server statistics support in silcd/server_internal.h
6101 SilcServerStatistics structure and around the server code. Also
6102 send some nice statistics information when client is connecting
6105 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Fixed channel ID decoding in server's JOIN command reply in
6108 silcd/command_reply.c
6110 * Fixed braodcasting of replace ID payload to not to send it if
6111 we are standalone server in silcd/packet_receive.c.
6113 * Fixed all channel message sending routines to not to send
6114 packets to clients that has router set, since they are routed
6115 separately in the same function earlier. Affects file
6116 silcd/packet_send.c and all channel packet sending functions.
6118 * In USERS reply, res_argv[i] are not allocated, the table
6119 is allocated. Thus changed that free the table, not its
6122 * In server's whois_check and identify_check if the client is
6123 locally connected do not send any WHOIS commands - they are not
6126 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Fixed some minor bugs in client when sending WHOIS command. The
6129 arguments was in wrong order.
6131 * Removed statis function add_to_channel from server in
6132 silcd/command.c that was previously used with the joining but
6135 * Tested USERS command in router environment successfully with two
6136 routers, two servers and two clients.
6138 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Reorganized the USERS command and command reply in client library
6141 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6142 When the command is given by user we register a pending command
6143 callback that will reprocess the command after the reply has been
6144 received from the server. When reprocessing the packet we then
6145 display the information. Thus, the USERS information is displayed
6146 now in the command callback instead of in the command reply
6147 callback. The processing of the command is same as previously
6148 when server has sent the command reply in the JOINing process.
6150 * Added to USERS command in silcd/command_reply.c to join the client,
6151 we didn't use to know about, to the channel after we've created
6152 a client entry for it. Also, for clienet we did know already still
6153 check whether it is on the channel or not and add it if not.
6155 * Removed silc_server_command_join_notify as the function and its
6158 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Changed the client's pending command handling to the same as the
6161 server's pending command handling. It is also now possible to
6162 execute command reply functions from other command reply
6163 function as the function callbacks for commands and command
6164 replies are one and same. The pending commands are not static
6165 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6166 in client connection context. Thus, pending commands are server
6167 connection specific as it is convenient.
6169 Changed the function silc_client_command_pending and
6170 silc_client_command_pending_del and added new function
6171 silc_client_command_pending_check. Removed the
6172 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6175 * Added cmd_ident, current command identifier, to the client
6176 connection context in lib/silcclient/client.h to keep track on
6177 command identifiers used in command sending. Client's command reply
6178 function handling now supports the mandatory command identifiers.
6180 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6181 funtions in client to fully support pending command callbacks.
6183 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6184 as one of the arguments to the application in the command reply
6187 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6188 before first releasing SILC but came back. Now it is removed again
6189 and should come back nomore. The FORWARDED flag was used only
6190 by the JOINing procedure by forwarding the command packet to router.
6191 Now, the JOINing procedure has been changed to more generic (due
6192 to various router environment issues) and FORWARDED is not needed
6193 anymore for anything. The protocol specification is yet to be
6196 Now, removed silc_server_packet_forward from server and the flag
6197 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6199 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Renamed NAMES command to USERS command. The NAMES was named that
6202 due to historical reasons. Now it is renamed. Also, rewrote
6203 parts of the USERS command. The nickname list is not sent anymore
6204 by the server. Only Client ID and mode lists are sent in the USERS
6205 command. Changed this also to the protocol specification.
6207 The client now resolves the names and stuff after it receives
6208 the USERS list from the server when joining to the channel.
6210 * WHOIS and IDENTIFY commands has been changed to support multiple
6211 Client ID's per command. One can now search for multiple users
6212 in the network by sending only one WHOIS or IDENTIFY command.
6213 Changed the code and the protocol specifications.
6215 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6216 uses silc_server_command_whois_parse to parse the request. */
6218 * If normal server, do not parse the WHOIS and IDENTIFY requests
6219 before sending it to the router. Saves some time.
6221 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Fixed JOIN command on client library. Wrong number of arguments
6224 used to crash the client.
6226 * Added silc_server_channel_has_global function to check whether
6227 channel has global users or not.
6229 * Added silc_server_channel_has_local function to check whether channel
6230 has locally connected clients on the channel.
6232 * The silc_server_remove_from_one_channel now checks whether the
6233 channel has global users or not after given client was removed from
6234 the channel. It also checks whether the channel has local clients
6235 on the channel anymore. If it does not have then the channel entry
6236 is removed as it is not needed anymore.
6238 * The silc_server_notify now checks on JOIN notify whether the joining
6239 client is one of locally connected or global. If it is global then
6240 the channel has now global users on the channel and that is marked
6241 to the channel entry. Also, it now saves the global client to
6242 global list who is joining and JOINs it to the channel. This is
6243 for normal server, that is.
6245 Changed silc_server_send_notify_on_channel,
6246 silc_server_packet_relay_to_channel and
6247 silc_server_packet_send_to_channel check if we are normal server
6248 and client has router set (ie. global client) do not send the
6249 message to that client, as it is already routed to our router.
6251 * Implemented LEAVE notify type handling in silc_server_notify
6254 * Tested LEAVE command in router environment successfully. Tested
6255 with two routers, two servers and two clients.
6259 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6261 * Implemented SIGNOFF notify type handling in silc_server_notify
6264 * silc_server_remove_id now removes the client entry from all channels
6265 it has joined and thusly sends SIGNOFF notify type.
6267 * Rewrote the NAMES list generation in server by removing two excess
6268 loops. The lists are created now inside one loop.
6270 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * silc_server_remove_channel_user checks now also global list
6273 for channel and client.
6275 * silc_server_new_channel_user checks now both local and global
6276 list for channel and client. Fixed a bug in client id decoding.
6277 Used to decode wrong buffer.
6279 * silc_server_channel_message checks now both local and global
6280 list for channel entry.
6282 * Tested channel joining (hence JOIN) in router environment
6283 successfully. Tested with two routers, two servers and two
6286 * Tested channel message sending in router environment successfully.
6288 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added silc_server_save_channel_key into server.[ch] to save the
6291 received channel key in Channel Key payload processing. It is
6292 also used in JOIN command reply handling.
6294 Equivalent function silc_client_save_channel_key added into
6295 client.[ch] into client library.
6297 * Changed JOIN command reply to send information whether the channel
6298 was created or not (is existing already) and the channel key
6299 payload. Changed protocol specs accordingly.
6301 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6302 the request was sent by ID and not by nickname. Crashed on
6305 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6308 now correctly save the received data.
6310 * silc_server_free_sock_user_data now notifies routers in the
6311 network about entities leaving the network.
6313 At the same time implemented functions silc_server_remove_id
6314 and silc_server_send_remove_id to receive and send REMOVE_ID
6315 packets. The packet is used to notify routers in the network
6316 about leaving entities. The ID removed will become invalid in
6319 * Added function silc_idlist_del_server into server. Removes and
6320 free's server entry from ID list.
6322 * silc_server_private_message function now checks, if we are router,
6323 that the destination ID really is valid ID, naturally.
6325 * In router when NEW_ID packet is received (for new client) the
6326 hash of the Client ID is saved in the ID Cache but the
6327 client->nickname is set to NULL, instead of putting the hash
6330 IDENTIFY command now also checks that client->nickname must be
6331 valid. If it is not if will request the data from the server who
6332 owns the client. Added new function
6333 silc_server_command_identify_check.
6335 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6336 to set the command to already allocated Command Payload.
6338 * Tested private message sending in router environment with two
6339 routers, two servers and two clients. Fixed minor bugs and now
6342 * Fixed segfault from client's NAMES command. Used to crash if
6345 * Forwarded packets must not be routed even if it is not destined
6346 to the receiver. Changed server code comply with this.
6348 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Added `require_reverse_mapping' boolean value to ServerParams
6351 structure. If TRUE (not default) the server will require that
6352 the connecting host has fully qualified domain name.
6354 If the reverse mapping is not required and hostname could not be
6355 found the IP address is used as hostname.
6357 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Implemented version string checking to both client and server.
6360 The check is incomplete currently due to the abnormal version
6361 strings used in development version of SILC.
6363 * Changed all command functions in server to use the new
6366 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Changed char *data to unsigned char *data in ID Cache system to
6369 support binary data as ID Cache data. Changed code to support
6370 binary data in lib/silccore/idcache.c.
6372 * Renamed silc_server_packet_relay_command_reply to
6373 silc_server_command_reply as it is normal packet receiving
6374 function. Rewrote the function to accept command replys for
6375 servers and not only for clients.
6377 * Mark remote router always as registered server if we are connecting
6378 to it. Otherwise, commands sent by the router to us are ignored.
6380 * All ID List find routines now returns the ID Cache Entry pointer
6381 as well if requested.
6383 * WHOIS command works now in router environment, tested with two
6384 routers, two servers and two clients.
6386 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6387 in router environment (as it is almost equivalent to WHOIS) but
6388 hasn't been tested thoroughly. Added new functions:
6390 silc_server_command_identify_parse
6391 silc_server_command_identify_send_reply
6392 silc_server_command_identify_from_client
6393 silc_server_command_identify_from_server
6395 * Disabled route cache adding because adding two different ID's with
6396 same IP replaces the old cache entry thus giving wrong route.
6397 The entry->router->connection is always the fastest route anyway
6398 so route cache may not be needed. Of course, new routes maybe
6399 established after receiving the ID when the entry->router->connection
6400 might not be anymore the most optimal.
6402 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Add route cache for received ID for fast routing.
6406 * Added silc_server_packet_route to route received packet on router
6407 that is not destined to us.
6409 * Renamed silc_server_get_route to silc_server_route_get.
6411 * Added id_string and id_string_len fields into SilcServer to
6412 include encoded ServerID for fast comparing without excess
6413 encoding of the ID's.
6415 * Cleaned up WHOIS command on server side. Added following static
6418 silc_server_command_whois_parse
6419 silc_server_command_whois_check
6420 silc_server_command_whois_send_reply
6421 silc_server_command_whois_from_client
6422 silc_server_command_whois_from_server
6424 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6425 arguments in command replies. All command functions should be
6426 updated to use this macro.
6428 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Minor typo fixes on command reply handling on server.
6432 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Added silc_server_command_add_to_channel internal routine to add
6435 the client to the channel after router has created the channel and
6436 sent command reply to the server.
6438 * Added generic silc_server_send_command to send any command from
6441 * Use static buffer with ID rendering instead of duplicating data.
6443 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Fixed a channel user mode bug when joining to a channel server gave
6446 everybody channel founder rights, oops.
6448 * We mark ourselves as the router of the incoming server connection
6449 if we are router ourselves. This way we can check in some packet
6450 sending functions whether it is locally connected server. For
6451 incoming router connections we put NULL.
6453 * For router sending packets locally means now always sending the
6454 packet cell wide; to local clients and local servers. For normal
6455 server sending packet locally means sending it to only local
6458 * Fixed the JOIN command to really work in router environment. If the
6459 channel is created it is always created by the router. Router is
6460 also responsible of making the initial joining to the channel,
6461 sending JOIN notify to the sending server and distributing
6462 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6463 does not exist server doesn't do anything else but forward the
6464 command to the router which performs everything.
6466 * Added silc_server_send_channel_key function to send the Channel Key
6469 * Added silc_server_create_channel_key to create new channel key. The
6470 channel key is now re-generated everytime someone joins or leaves
6471 a channel, as protocol dictates. Note: channel->key_len is the
6474 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6477 packet_receive.[ch] to separate packet sending and receiving
6478 routines. The server.[ch] now includes everything else including
6479 actual packet processing (writing and reading data) and other
6482 Renamed silc_server_private_message_send_internal to
6483 silc_server_send_private_message. The routine is still though
6484 used only to relay private messages as server does not send
6485 private messages itself.
6487 Renamed silc_server_new_channel to silc_server_create_new_channel
6488 and added new function sicl_server_new_channel that handles the
6489 incoming New Channel packet. Added also new sending function
6490 silc_server_send_new_channel to send New Channel Payload.
6492 * Added new function silc_server_notify to process incoming notify
6493 packet to the server/router. Server may then relay the notify
6494 to clients if needed.
6496 * Added new function silc_server_new_channel_user to process incoming
6497 New Channel User packet. Router will redistribute the packet and
6498 send JOIN notify to its local clients and locally connected servers
6499 if needed. Normal server will send JOIN notify to its local client
6500 on same channel when received this packet. Added also corresponding
6501 sending function silc_server_send_new_channel_user to sent the
6504 * Added boolean route argument to send_notif_to_channel and
6505 packet_send_to_channel functions to attempt to route the packet
6506 if it is TRUE and send only locally if it is FALSE.
6508 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * silc_server_replace_id now broadcasts the received replace ID
6511 packet if it is not broadcast packet already. The router must
6512 broadcast to inform other routers about changed ID.
6514 * Added backpointer to server's router into SilcServer context in
6515 silcd/server_internal.h.
6517 * Fixed silc_server_packet_broadcast to send correct broadcast
6520 * The channel key is now distributed to the local client as soon
6521 as it is received from the router (in router environment) so that
6522 no other packet may be sent for the channel until client has
6525 * silc_server_remove_channel_user now broadcasts the received
6526 Remove Channel User packet if it is not broadcast packet already.
6527 The router must broadcast to inform other routers about removed
6530 * Added users field into SilcPacketContext that is a reference count
6531 of the context. One can increase the reference count by calling
6532 silc_packet_context_dup which is now changed to just increase the
6533 reference count instead of duplicating the data. The reference
6534 count is decresed by calling silc_packet_context_free that will
6535 free the data after the reference count hits zero.
6537 For now on the packet context and everything allocated into it
6538 (including the raw packet from network) must be freed by calling
6539 the new silc_packet_context_free function. Added also new function
6540 silc_packet_context_alloc that must be used now to allocate the
6541 context. This also means that if a routine is asynchronous from
6542 silc_[client/server]_packet_parse_type the packet context must
6543 be duplicated by calling silc_packet_context_dup. Otherwise it
6544 gets free'd after silc_[client/server]_packet_parse_type returns.
6545 Also, one must remember that if packet is duplicated then its
6546 reference count must be decresed by calling the free function as
6547 many times as it was duplicated.
6549 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6550 from both client and server.
6552 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Made joining to a channel working in router environment.
6556 * Cleaned up JOIN command on server side and create function
6557 silc_server_command_join_channel internal routine to make the
6560 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Changed silc_command_pending list to SilcDList. Also, added
6563 `ident' field to SilcServerCommandPending structure to identify
6564 the reply and to call correct callback.
6566 Added silc_server_command_pending_check function to replace the
6567 corresnponding macro. The silc_command_pending list is not
6570 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6571 to set identifier to previously allocated Command Payload. It
6572 is used to set identifier for command when resending Command
6575 * Added silc_command_payload_encode_payload to encode Command
6576 Payload buffer from SilcCommandPayload structure.
6578 * Added silc_argument_payload_encode_payload to encode Argument
6579 payload buffer from SilcArgumentPayload structure.
6581 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Changed WHOIS command to support router connection on server side.
6584 The whois request is always sent to router unless the server is
6585 standalone server. After server has received the reply from the
6586 router will it send the reply to the client.
6588 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6589 broadcast received broadcast packet. The function is used only
6590 by router. The broadcast packet is always sent to the router's
6593 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6594 render given ID to printable string, for log files for example.
6596 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Made basic router to router connections working. At least they
6599 can now connect to each other but nothing really works the way
6600 they are supposed - yet.
6602 * Added new initiator token to RouterConnection configuration
6603 file in silcd/serverconfig.[ch]. It is used to tell whether we
6604 are the initiator to the remote router or whether we'll expect
6605 the other end to connect.
6607 * Moved registering of listener task to silc_server_init, hence
6608 the server starts listenning as soon as it is run, even if it
6609 does not have connections to other routers. Let's see how well
6612 * Changed default connection retry timeouts for more suitable in
6615 * Removed cipher and such arguments from silc_idlist_add_client
6616 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6617 Added new function silc_idlist_add_data to add the keys and stuff
6620 * Added SilcIDListData structure and added it to SilcClientEntry
6621 and SilcServerEntry as their first field in the structure. This
6622 way we can explicitly cast the ID entries to the SilcIDListData
6623 structure and get common data for the entries. In past, we had
6624 to first check what type of connection it is and then cast it to
6625 correct ID entry type. Now, we can directly cast the opaque
6626 pointer to the SilcIDListData (no matter what ID entry it actually
6627 is) and get the data needed.
6629 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6632 in some circumstances even if threre were timeout tasks, though not
6633 IO tasks, but tasks anyway. Now fixed.
6635 * Defined SilcServerConnection structure to hold connection specific
6636 stuff about directly connected servers and routers. The definition
6637 is currently in silcd/server_internal.h. I thought about having
6638 a bit more important role fro this struct but for now it is used
6639 only when connecting to other server (or router actually).
6641 * Added connecting retry support in server when connecting to
6642 router(s). The retry feature implement exponential backoff
6643 algorithm. Also, added SilcServerParams structure to hold default
6644 parameters for server. For now, it include these retry settings
6645 and are hard coded. After server is moded to be as Silc Server
6646 Library this structure will be more important.
6648 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6650 * Changed client librarys channel->clients table to SilcList and
6651 changed code accordingly.
6653 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Changed client's channel table to SilcList and changed code
6656 accordingly. Also changed SilcChannelClientEntry to include back-
6657 pointer to the channel so that client entry can use that structure
6658 as list as well and we have fast cross-reference to the channel.
6659 This change dramatically decreased the complexity of channel
6660 handling with client entry and vice versa (removed one extra
6661 loop when searching for channel entry from many functions).
6663 * Changed server->sim from table to SilcDList and changed code
6666 * NAMES command can now be used from user interface. It will show
6667 the user list on the channel, neatly.
6669 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6670 Code now saves realname of the user if it becomes available.
6672 * Renamed configure.in to configure.in.pre and made ./prepare
6673 script to automatically add correct version string to
6674 configure.in which it creates from configure.in.pre.
6676 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6678 * NAMES command reply now shows users mode with the nickname when
6681 * Moved silc_client_ch[u]mode[_char] functions from
6682 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6683 place sucks, they are utility functions and should be in some
6686 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6688 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6691 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6695 * Added TRQ (efficient deque and list library) into lib/trq. This is
6696 a very good list library that is currently used in the SILC. Defined
6697 SilcList API over the library because I didn't like the API very
6698 much. See lib/trq/silclist.h for the API and examples of how to
6699 use the API. Fixed various places in the code to use the new
6700 SilcList API. The SilcList is meant for lists that has a structure
6701 already defined as a list. It is not suitable to add just some
6702 context to the list (in TRQ, the context is the list actually).
6704 So, I defined SilcDList that can be used for the purpose where
6705 predefined list structure does not exit. This can be used as
6706 such list. Now some context just can be added to the SilcDList.
6707 Currently this list is not used in the SILC just yet, though there
6708 are a lot places where this can replace dynamically allocated
6709 tables and I will fix these places, later, to use SilcDList.
6710 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6711 and use TRQ internally).
6713 Also fixed some annoying warning messages that the original TRQ
6714 code generated. Also minor changes to TRQ's Makefile.in.
6716 * Added support for querying by Client ID to both WHOIS and
6717 IDENTIFY commands into server, as required by the protocol.
6719 * Removed method function pointers from SilcBuffer structure. They
6720 weren't used to anything and just increased the context size for
6721 no good reason. This change also made silc_buffer_alloc and
6722 silc_buffer_free functions inline functions.
6724 * Disabled command flooding detection support until it's fixed so
6725 that it accepts commands in but does not execute them more than once
6728 * Added silc_net_localhost(), to return local hostname, into
6729 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6730 that must be initialized before calling silc_client_init.
6732 * Added new function: silc_server_send_notify_on_channels to send
6733 notify messages to all channels client has joined. It is assured
6734 that the message is sent only once per client.
6736 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6737 lib/silcutil/silcutil.[ch] as silc_format function. The new
6738 function is generic and is used by server as well, not only by
6739 the logging routines.
6741 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6742 the provided version string was not acceptable. Added new function:
6743 silc_ske_check_version into lib/silcske/silcske.h. The function
6744 must be implemented by the application (client or server) and it
6745 does not reside in the SKE library. The function checks the version
6746 string remote end sent.
6748 * Added back pointers (to opaque context and to SilcSocketConnection)
6749 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6751 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6752 duplicate packet context structure.
6754 * Changed `notify' client operation to send same arguments as client
6755 receives from server except for ID's. ID's are mapped to correct
6756 ID entry and that is returned. Also, if channel entry is not sent
6757 by server but the notify is for channel the channel entry is sent
6758 to application (otherwise application doesn't know that it is for
6759 channel (library gets it from packet's Destination ID)).
6761 * Added silc_client_remove_from_channels into client library to
6762 remove a client from all channels it has joined to. Used when
6763 received SIGNOFF notify from server. Added also new function
6764 silc_client_replace_from_channels to replace old ID entry with
6765 new ID entry on all channels. Used when received NICK_CHANGE
6768 * Fixed ID Cache list handling in silc_idlist_get_client in
6769 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6770 to get (or query) client by ID.
6772 * Updated TODO list.
6774 * Added connection authentication status message defined by the
6775 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6776 support for these into the code in client and server side.
6778 * Added generic function silc_client_send_command to send any command
6779 with variable argument list. Application should use this function
6780 to send commands if the command functions provided by the library
6781 does not suite for the application's user interface needs.
6783 * Added new `failure' client operation. Application is notified about
6784 received failure packet if client is executing a protocol. In this
6785 case the protocol's execution has failed.
6787 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6788 is required by the protocol.
6790 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6791 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6794 * Added status flag to SilcSKE object to indicate realtime status
6795 of the SKE protocol.
6797 * Application receives now exactly same command reply arguments as
6798 the library receives from server. However, if ID is received the
6799 corresponding ID entry is returned to the application (eg. Client
6800 ID is mapped to correct SilcClientEntry entry and that is returned).
6801 Changed command_reply client operation due to this change.
6803 * Changed all ID's in commands and in command replys as ID Payloads.
6804 Change affected both client and server side codes.
6806 All ID's sent in SILC network (with execption of ID's in SILC
6807 Packet header) are sent in ID Payload to support variable length
6810 * Server now notifies nick changes and notifies all clients on
6811 the channels about the new nickname (about the new Client ID,
6814 * Implemented CMODE command to change channel modes. Supports all
6815 channel modes defined by the protocol specs except ban and invite
6816 lists. (Also, private channel key mode is supported but support for
6817 setting private channel key in client is missing, thus, this mode
6818 has no effect on client side (except that server requires that the
6819 client uses private channel key and normal channel traffic does not
6822 Also, invite mode works per se, but INVITE command does not work
6823 yet correctly, so you can set channel as invite only channel but
6824 inviting clients to the channel does not work (it is yet to be
6825 thought what's the best way to do it).
6827 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6828 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6829 Implemented CUMODE command to change user's mode on the channel.
6830 Supports all modes defined by the protocol specs.
6832 * Added NAMES command reply to return users modes on the channel.
6834 * Removed unnecessary and slow ciphers from lib/silccrypt.
6836 * Set SO_KEEPALIVE option to connection sockets by default.
6838 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6840 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6841 redefined the Notify Payload into protocol specs.
6843 * Added silc_id_payload_parse_id to get ID directly from raw
6846 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6849 accept searching by Client ID as well.
6851 * Added support for LEAVE and SIGNOFF notify types in client library.
6853 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6854 to parse ID Payload from raw data.
6856 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * Added flags parameter into silc_ske_assemble_security_properties
6859 function in lib/silcske/silcske.[ch].
6861 * Changed notify client operation to fit better for notify messages
6862 sent by server. The notify payload received from server is now
6863 passed to the application (after parsing it to SilcNotifyPayload).
6864 It is application's responsibility to retrieve the arguments
6865 from the payload and show the message the way it wants. The message
6866 sent by server is implementation specific.
6868 * Changed public keys to comply with the protocol specification.
6869 Old public keys are not supported anymore and are not compatible.
6871 * Removed nickname from Channel Payload as the latest draft removed
6872 it. The client must resolve the nickname from the NAMES command
6873 reply received when it joined the channel.
6875 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6877 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Fixed some errors in protocol specification drafts.
6881 * Created lib/silccore/silcnotify.c to implement Notify Payload
6882 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6883 generic payloads described by protocol specifications. The file
6884 includes implementations for ID Payload and Argument Payload.
6886 * Changed Command Payload implementation to use the new Argument
6887 Payload. Changed command_xxxx_payload to command_payload_xxxx
6888 to comply with SILC coding conventions.
6890 * Added suppport for Argument Payload handling in Notify Payload
6891 implementation as protocol requires it. Added the new support
6892 into server and client lib as well.
6894 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Added support for multiple nicknames on same channel. [n] is
6897 added locally to the nickname if there are more than one same
6898 nicknames on the channel.
6900 * Server now sends all nicknames that matched WHOIS request.
6901 Client also shows the list received from server.
6903 * Added TOPIC command to client side. User can now set and show
6904 current topic on channel.
6906 * Added MOTD command to client and server. Also, server sends the
6907 motd when client connects to the server.
6909 * Changed version strings to comply ISO 8601.
6911 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Fixed protocol error handling in client library. It should now
6914 cope even if the SKE fails for some reason.
6916 * Made new protocol specification drafts for submitting to IETF.
6918 * Implemented TOPIC command to server in silcd/command.c.
6920 * Added two new notify types into lib/silccore/silcnotify.h:
6921 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6922 notify nickname change and topic setting/change on a channel.
6924 * API change of command_reply operation in client library. The
6925 application gets now the status type received from server as well.
6927 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6929 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6931 * Cras fixed and optimized the packet handling even further and
6932 it should work now. Minor change to the prototype of function
6933 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6935 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Added new function into lib/silcutil/silcschedule.[ch]:
6938 silc_schedule_with_fd to select() a specified fd. The function
6939 returns after timeout expires or data arrives or goes. The
6940 function is used by packet routines to wait that all data is
6941 received from network.
6943 * Fixed data reading from network in lib/silccore/silcpacket.c.
6944 The code now assures that all data is read from the fd and then
6945 continues packet processing. This was a bug fix since the code
6946 used to drop some data in some circumstances.
6948 * Added new function into lib/silcclient/client.[ch]:
6949 silc_client_start_key_exchange to start key exchange after
6950 connection has been established to server. The code internally
6951 now uses this funtion but its main purpose was to provide it
6952 for applications that perform their own connecting. After
6953 application has created a connection it merely calls this
6954 function to start the key exchange between client and server.
6955 The library takes care of everything else after that.
6957 Updated also lib/silcclient/README to explain the usage of
6960 * Do not send to application information that connection has
6961 been established. Application gets notified it by connect
6964 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Applied cras's patch to add silc_schedule_one function. The
6967 function runs scheduler once and returns.
6969 * Fixed the scheduler after cras messed it up. The timeout
6970 handling works now as it's supposed to work.
6972 * Added into lib/silccore/ silcnotify.h to include notify
6973 message types support. Changed silc_server_send_notify*
6974 functions, in server.[ch], to support those new notify types.
6975 Added the support for the notify types into client library,
6976 as well. Added new notify client operation into ops.h in
6979 * Changed silc_server_packet_send_to_channel to send normal
6980 packets instead of just channel message packets. The function
6981 is now used to send the notify packets to channels. It is not
6982 used to send channel message packets anymore, as server never
6985 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6986 va_arg()s as it seems to require it nowadays. I guess, if SILC
6987 is compiled with older va_arg() the new code should work anyway.
6989 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6991 * Splitted core library. Core library (lib/silccore) includes
6992 now only SILC protocol specific core (and common) components.
6993 Created new utility library (lib/silcutil) that includes more
6994 generic purpose stuff. The stuff for util library was taken
6995 from the old core library. This was minor and easy split.
6997 * Created SILC Client Library (lib/silcclient) that includes
6998 implementation of the SILC client without user interface. This
6999 was major move from silc/ directory. The code has been changed
7000 so that it is transparent towards the user interface. The
7001 silc/ directory includes now the same user interface as before
7002 and it uses the new client library. Read lib/silcclient/README.
7003 Basicly, the client library performs everything else related
7004 to SILC except user interface handling. Also, configuration
7005 files are considered to be part of user interface and library
7006 does not handle them.
7008 This change also changed a lot of structures, function naming etc.
7009 Most important change was that SilcClientWindow object was
7010 renamed to SilcClientConnection in the client library. Created
7011 also new file lib/silcclient/ops.h. Also added new files
7012 silc/local_command.[ch] and silc/client_ops.[ch].
7014 All these changes were made to make it easier for user interface
7015 designers to create what ever user interface for the SILC client
7018 It is also expected that the server will be moved to lib
7019 directory as well and SILC Server Library will be created;
7020 sometimes in the future.
7022 * Removed Local commands from lib/silccore/silccommand.h as
7023 they are application specific and new client library does not
7024 handle any of those anymore.
7026 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7027 old client implementation in silc/.
7029 * Added support for callback functions in SILC_LOG_* macros.
7030 Application can now set its own callbacks that will be called
7031 instead of using the default functions that will always print
7032 the debug messages to stderr (or stdout). Also, debugging can
7033 now be disabled by setting silc_debug to FALSE and re-enabled by
7034 setting it to TRUE. Note, that logging will still work even
7035 if debugging is disabled.
7037 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7038 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7039 silc_log_reset_debug_callbacks.
7041 * To enable debugging in silc client one must give now -d
7042 option on command line.
7044 * Changed silc_schedule_init to automatically allocate task queues
7045 if they are not allocated before calling it.
7047 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Added GMP 3.1 into math library.
7051 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7053 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7054 a channel in SILC network. The packet is used by servers and
7055 routers to notify other routers that user has left a channel.
7056 This little feature was missing until now. Added the feature
7057 to protocol specification as well.
7059 Added functions: silc_server_send_remove_channel_user and
7060 silc_server_remove_channel_user into server.[ch].
7062 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7063 lib/silccore/silcpacket.h. However, they are not implemented
7066 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Fixed joining to a channel and sending channel messages
7069 between server and router. The channel message sending should
7070 now work inside a cell.
7072 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Fixed the private message sending between server and router.
7075 The private message sending should now work inside a cell.
7077 * Added silc_server_replace_id into server.[ch] to replace
7078 existing ID in the SILC network.
7080 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7081 and silc_idlist_replace_server_id into idlist.[ch] in server.
7083 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Fixed the server to server connections. Server can again now
7086 connect to router. Router to router connections probably does
7089 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Added dynamic protocol registering support. Now protocols can
7092 registered and unregistered on the fly. Patch by cras.
7094 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Added lib/contrib directory to hold routines that some platforms
7097 don't have but are needed by SILC.
7099 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7100 into lin/contrib to provide getopt() and getopt_long() for
7101 those who don't have it.
7103 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Added AWAY command to client. When away message is set and
7106 client receives a private message packet the client automatically
7107 replies to the sender with the away message.
7109 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7110 bug seemed to be the cause of recent problems when compiling
7113 * Added version detection support to SKE protocol specification
7114 and added the new changes to the SKE implementation as well.
7115 There were other minor changes in the SKE protocol as well.
7117 Many changes in lib/silcske/silcske.[ch] and in
7118 lib/silcske/payload.[ch].
7120 * Added ^U functionality, clear input line. Patch from cras.
7122 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Mainly small bugfixes on core library. Fixed some debugging
7125 logging and buffer overflow in silclog.c.
7127 * Updated config.sub and config.guess on the distribution tree.
7129 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7131 * Added command lagging support in server. Client may execute
7132 commands now only once in two seconds.
7134 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Optimized packet reception. MAC computation and checking is now
7137 also more optimized. A lot previously duplicated code is now
7138 used as generic by both client and server.
7140 * Fixed key pair generation in clientutil.c
7142 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Added into lib/silccore/silcbufutil.[ch] new function;
7145 silc_buffer_realloc.
7147 * Moved generic packet sending/encryption functions to
7148 lib/silccore/silcpacket.[ch] from client and server. Some
7149 rewriting of the functions.
7151 * Moved all generic packet reception/decryption functions to
7152 lib/silccore/silcpacket.[ch] from client and server. The
7153 packet processing is now much cleaner in both client and server.
7154 These were major changes in both client and server.
7156 * Created many common functions in server to do packet sending.
7157 Previously code were duplicated a lot, this has been removed
7160 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * Rewrote major parts of the ID cache system. Don't know
7163 whether it is better now or not but at least the API is more
7166 * Major rewrite on ID cache stuff on client because of the ID
7167 cache API changes. Added idlist.c to client.
7169 * Also major rewrite on ID cache stuff on server as well.
7170 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7171 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7172 in hand, instead they are all put into the ID cache system now.
7173 All server_idlist_* routines uses ID cache now instead of
7174 traversing its own lists (those lists does not exist anymore).
7175 SilcIDList though still exists. Also, SilcXXXEntry's are
7178 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Finally made the SKE implementation compliant to the protocol
7181 specification. All mp integers are now binary encoded as
7182 opposed being HEX encoded.
7184 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7187 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7188 functions: silc_[encode/decode]_pem. Also added function
7189 silc_encode_pem_file to PEM encode with newlines ('\n') for
7192 * SILC public keys are now encoded either PEM or binary. Same
7193 option is for private keys as well. By default private keys
7194 are binary encoded and public keys PEM encoded. Silly HEX
7195 encoding were removed.
7197 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7198 function to create fingerprints.
7200 * Fixed a bug in SHA1; does not change the original data anymore.
7202 * Partly implemented INFO command on client and server side.
7203 Fixed CLEAR command. Changes to SERVER command; show current
7204 server(s) when giving command without arguments. Added
7205 VERSION command to client.
7207 * Added check to server that unregistered connections cannot
7208 execute commands (unless it is specificly allowed).
7210 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Fixed screen refresh.
7214 * Fixed channel joining bug from client. On some circumstances
7215 client tried to join to a channel it had already joined.
7217 * Added public key verification process into client's protocol.c.
7218 The client now verifies the public key from user and saves
7219 it into ~./silc/serverkeys/ directory.
7221 Added into: clientutil.[ch]: silc_client_verify_server_key.
7223 * Changed SKE protocol's silc_ske_initiator_finish function
7224 to accept callback function that verifies the received public
7225 key. Removed old silc_ske_verify_public_key function.
7227 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7229 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7230 silc_pkcs_private_key[_data]_set.
7232 * Made the password and public authentication more cleaner in
7233 server's protocol.c.
7235 * Removed historic and obsolete protocol `channel_auth' from
7236 both client and server.
7238 * Removed wrong way of sending command status messages from
7239 server to client in server's command.c. The old way violated
7240 protocol specification.
7242 Changes to silccore/silccommand.[ch]: removed
7243 silc_command_encode_status_payload -> not needed anymore,
7244 changed silc_command_encode_payload_va to accept extra
7245 argument on variable argument list. The argument type must
7246 now be provided to the function. Also, added new function:
7247 silc_command_encode_reply_payload_va which is same as
7248 normal command_encode_payload_va except command status type
7249 is provided as extra argument.
7251 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7253 * Added ~./silc directory handling. The directory includes the
7254 public and private keys for the client.
7256 Added silc_client_check_silc_dir, silc_client_create_identifier
7257 and silc_client_load_keys.
7259 * Implemented SILC protocol compliant public key. Added public
7260 and private key saving to and loading from files.
7262 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7263 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7264 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7265 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7266 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7268 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7269 silc_pkcs_load_[public/private]_key.
7271 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7273 * Added silc_server_get_route (route.[ch]) to get connection
7274 data for the fastest route for given ID.
7276 * Implemented INVITE command on client and server. The command
7277 were re-defined in the SILC Protocol Specification and the
7278 implementation now complies with the specification.
7280 * Implemented PING command on client and server.
7282 * Implemented NAMES command on client and server. The server side
7283 supports currently only normal server not router server yet.
7284 Some changes to NAMES definition in SILC protocol specification.
7286 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7288 * Implemented LEAVE command on client and server.
7290 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7291 again. This change was made to the protocol as well. Server
7292 should not violate the protocol specification anymore.
7294 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7296 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7297 was tested. SOCKS4 was not but should work anyway.
