155 * ROBOdoc documented the lib/silcske/silcske.h, and improved
156 the SKE interface a bit.
158 * Fixed padding problem in PKCS#1. The padding was not actually
159 random since the random number generator was used incorrectly.
160 This security bug affects only when encrypting with PKCS#1, and
161 it is not currently used at all in SILC. SILC only use signing
162 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

243 algorithm parts and created new file silcalgs.conf, that
244 is now included from the example_silcd.conf.in.
246 * Optimized the silc_server_connect_to_router_second to take
247 the connection configuration object from the SilcServerConnection
248 object instead of finding it during the connecting phase.
249 Added the configuration object to SilcServerConnection struct.

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

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

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

383 become invalid in the callback but it was referenced after
384 the callback returned.
386 Do not allow auto rehashing of hash table during the
387 silc_hash_table_foreach operation, for same reasons as it is
388 not allowed for SilcHashTableList. Affected files are
389 lib/silcutil/silchashtable.[ch].

417 rehashed. It is now guaranteed that auto rehashable tables
418 are not rehashed while tarversing the list. Also defined that
419 silc_hash_table_rehash must not be called while tarversing
420 the table. Added function silc_hash_table_list_reset that must
421 be called after the tarversing is over. The affected files are
422 lib/silcutil/silchashtable.[ch].
424 * Changed all hash table traversing to call the new
425 silc_hash_table_list_reset in server and in client library.
427 * Added function silc_client_on_channel to return the

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

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

557 * Removed the SilcClientCommandDestructor from the client
558 libary, it is not needed anymore. Affected files are
559 lib/silcclient/silcapi.h, command[_reply].[ch],
560 client_notify, idlist.c.
562 * Fixed GETKEY command to first resolve client, and then
563 resolve the server only if the client was not found, instead
564 of resolving both at the same time. Affected file is
565 lib/silcclient/command.c.
567 * Added silc_client_start_key_exchange_cb and lookup the
568 remote hostname and IP address before starting the key
569 exchange with server. The affected file is
570 lib/silcclient/client.c.
572 * The server's public key is now saved using the IP address
573 of the server and not the servername for the filename.
574 The hostname public key filename is checked as an fall back
575 method if the IP address based filename is not found.
577 Fixed the GETKEY command to save the fetched server key
580 Print the remote server's hostname now when new key is
581 received during connection process. Affected file is
582 irssi/src/silc/core/client_ops.c.
584 * Return always our own public key to the client if it asks
585 for it with GETKEY command. Affected file silcd/command.c.
587 * Removed the use_auto_addr variable from default config
588 file since it was in wrong section. Affected file is
591 * Fixed TOPIC_CHANGE notification to not route it when it
592 was sent using silc_server_send_notify_to_channel function.
593 Affected file silcd/command.c.
595 * Fixed silc_server_send_notify_kicked to send the kicker's
596 Client ID also, it was missing. Affected files are
597 silcd/command.c, silcd/packet_send.[ch].
599 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Do not save client history information in SERVER_SIGNOFF.
602 Fixes the bug in normal server that it does not detect
603 the client becoming valid after the server becomes back
604 online. Affected file silcd/server_util.c.
606 * Added `sock_error' field into the SilcSocketConnection
607 context. When error occurs during socket operation (read
608 or write) the error is saved. Added also new function
609 silc_socket_get_error to return human readable socket error
610 message. Affected files are lib/silcutil/silcsockconn.[ch],
611 lib/silcutil/unix/silcunixsockconn.c, and
612 lib/silcutil/win32/silcwin32sockconn.c.
614 * The server now prints the socket error message in the
615 signoff for client. Affected file silcd/server.c.
617 * Fixed the `created' channel information sending from router
618 to server in JOIN command. Checks now whether the channel
619 really was created or not and set it according that.
621 Fixed the JOIN command to use the client entry's current
622 ID during the joining procedure instead of the one it sent
623 in the command (it is checked though), since it can change
624 between the packet processing and command processing, and
625 would just case unnecessary pain in the client end. Affected
626 file silcd/command.c.
628 * Fixed a channel key payload sending to use correct channel
629 ID when the server was forced to change the channel's ID by
630 router. Router sent the key payload with the old Channel ID.
631 Affected file silcd/packet_receive.c.
633 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
635 * Call silc_server_save_channel_key only if the key payload
636 was provided in the JOIN command's command reply. Affected
637 file silcd/command_reply.c.
639 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
641 * Fixed silc_mp_sizeinbase to return the value correctly with
642 MPI. Affected file lib/silcmath/mp_mpi.c.
644 * Fixed the stop_server signal to correctly stop the scheduler
645 and gracefully stop the server when SIGTERM or SIGINT signals
646 are received. Affected file silcd/silcd.c.
648 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
650 * Simple handling of TERM and HUP signals. Also added some log
651 flushing call around. Affected file is
654 * Fixed small bugs in silclog.c. Now buffering output will take
655 effect after 10 seconds since startup: This will ensure that
656 no important startup messages are lost. Also output redirection
657 will preserve original format ([Date] [Type] message).
658 Affected file is lib/silcutil/silclog.c.
660 * Added two options to the config file, in the logging section:
661 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
662 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
664 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Do not print the warning about log files not being initialized
667 more than once to avoid excess logging. Affected file is
668 lib/silcutil/silclog.c.
670 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
671 the SIM copying in make install in Makefile.am.pre.
673 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
675 * Rewritten silclog APIs. Globally interesting changes follows:
676 silc_log_set_files() changed to silc_log_set_file().
677 silc_log_set_callbacks() changed to silc_log_set_callback().
678 ROBOdoc documented silclog header file.
679 SilcLogCb now returns bool to wether inihibit the default
680 handler or not (to keep the old behaviour return always TRUE).
681 The new APIs should also fix the problem of the
682 silcd_error.log file that was written in the current directory.
685 Log files streams will remain opened after silc_log_set_file()
686 call, means less CPU usage notably on high traffic servers.
687 File streams are now full buffered, and flushed to the disk
688 every 5 minutes, lesses HD activity and CPU usage.
689 Messages can be redirected, allowing admins to configure
690 one single logfile for all server messages.
691 the silc_log_quick global variable to activate fast-logging.
692 Affected files lib/silcutil/silclog.[ch]
694 * Changed some code to conform new silclog APIs. Affected
695 files are doc/example_silcd.conf.in, silcd/server.c
696 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
699 * Fixed a memory leak that could occur in some situations.
700 Affected file silcd/serverconfig.c.
702 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
704 * Added the silc_client_del_client to remove the client from
705 all channels as well. Affected file lib/silcclient/idlist.c.
707 * Fixed the client library to correctly remove the client
708 from all channels when the client entry is being destroyed.
709 Affected file lib/silcclient/client_notify.c, command.c.
711 * Added auto-nicking support to the client library. If the
712 applicatio now sets client->nickname it will be sent to the
713 server after connecting by the library. This way for example
714 SILCNICK (or IRCNICK) environment variables will have effect
715 and always change the nickname automatically to whatever
716 it is wanted. Affected file lib/silcclient/client.[ch].
718 * Renamed silc_server_command_bad_chars to the
719 silc_server_name_bad_chars and moved it to the
720 silcd/server_util.[ch]. Added also new function
721 silc_server_name_modify_bad to return nickname that
722 includes bad characters as new nickname without those
723 bad characters. This check and modify is now used in
724 silc_server_new_client when the username is initially set
725 as nickname, so it must be checked to be valid nickname.
726 Affected file silcd/packet_receive.c.
728 * The nickname length is now taken from the packet for real
729 and not trusted to strlen() since it clearly can return
730 wrong length for nickname including bad characters. This
731 also applies to channel names. Affected file silcd/command.c.
733 * Removed the lib/silcsilm/modules directory. Modules are now
734 compiled into the lib/silcsim. Fixed the copying of the
735 modules to follow symbolic links in Makefile.am.pre.
737 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Fixed silc_string_regexify list creation. Fixes bugs with
740 BAN and INVITE commands in server. The affected file is
741 lib/silcutil/unix/silcunixutil.c.
743 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
745 * Removed the command destructor entirely from the server's
746 command and command reply routines. It is not needed, and
747 its usage was buggy and caused crashes. Affected files are
748 silcd/command[_reply].[ch].
750 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Cancel protocol and NULL sock->protocol if timeout
753 occurred during protocol. Affected file silcd/server.c.
755 * Cancel protocol timeouts always before calling the final
756 callback, to assure that after final callback is called
757 no other state will be called for the protocol anymore.
758 Affected file silcd/protocol.c.
760 * Print error log if incoming connection configuration could
761 not be found. Affected file silcd/server.c.
763 * Fixed JOIN command to correctly save the founder mode
764 to the client on normal SILC server, when the channel
765 was created by the router. Affected file silcd/command.c.
767 * Fixed LIST command (hopefully) to send correct reply
768 packets. Affected file silcd/command.c.
770 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
772 * The silc_packet_receive_process now returns FALSE if the
773 read data was invalid packet, and TRUE if it was ok.
775 The server now checks that if unauthenticated connection
776 sends data and its processing fails the server will close
777 the connection since it could be a malicious flooder.
779 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
781 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Make sure the warning about error opening a log file is
784 printed only once and not everytime it fails (produces
785 too much useless log). Affected file lib/silcutil/silclog.c.
787 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
789 * Made the silc_server_daemonise() function more readable.
790 Affected file silcd/server.c.
792 * Pid file is now optional, the user may comment it out from
793 the config file. Removed define SILC_SERVER_PID_FILE, we
794 don't need a default any longer. Affected file
795 configure.in.pre, lib/Makefile.am.pre.
797 * Make some use of the pid file. The server now dies at startup
798 if it detects a valid pid file on his path. The server would
799 die anyway in this circumstance, because of the bind() failure.
800 Affected file silcd/silcd.c.
802 * No longer compiling lib/dotconf.
804 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
806 * Fixed JOIN command parsing not to crash. Affected file
807 lib/silcclient/command.c.
809 * Fied the NICK_CHANGE notify to add the new client entry
810 even it is resolved. This removes an <[unknown]> nick
811 thingy bug in the client. Affected file is
812 lib/silcclient/client_notify.c.
814 * Do not try to allocate 0 bytes (efence does not like it)
815 in lib/silccore/silccomand.c when encoding payload.
817 * Do not take IRCNICK as nickname in Irssi SILC client since
818 it is not possible to set nickname before hand connecting
819 the server (TODO has an entry about adding auto-nicking
822 * Changed the silc_server_command_pending to check whether
823 there already exists an pending entry with the specified
824 command, command identifier and pending callback. This is
825 to fix IDENTIFY and WHOIS related crashes that may register
826 multiple pending commands with same identifier. Affected
827 file silcd/command.c.
829 * Fixed the server to reconnect to the router even if it
830 was already reconnecting and EOF was received. This to
831 fix a possibility that the server wouldn't ever try to
832 auto-reconnect to the router. Affected file silcd/server.c.
834 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
836 * Fixed the server's password authentication to use the
837 length of the locally saved password, and not the one
838 sent in the packet. Affected file silcd/protocol.c.
840 * Fixed same password authentication problem in the
841 Authentication Payload handling routines in
842 lib/silccore/silcauth.c.
844 * Yet another password authentication problem fixed with
845 channel password handling in silcd/command.c.
847 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
849 * If first character of string in silc_parse_userfqdn is '@'
850 then do not parse it. Affected file is
851 lib/silcutil/silcutil.c.
853 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
855 * Fixed minor bug in IDENTIFY command reply sending, which
856 caused various weird problems during JOIN when it was
857 resolving names for users. Affected file silcd/command.c.
859 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
861 * Fixed the IDENTIFY command reply sending to chech better valid
862 clients. It was possible to send incomplete list of replies.
863 Affected file silcd/command.c.
865 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Added silc_client_command[s]_[un]register functions now to
868 dynamically register the commands in client library. Removed
869 the static table of commands. This allows the client library
870 to call commands without causing the application to know about
871 what commands library has called.
873 Removed the INFO command reply kludge to detect when the command
874 was called by library. Now library use its own command reply
875 function for INFO command.
877 Added function silc_client_command_call to call a command.
878 Application can use it to call command, not access the structure
881 Now all commands that are sent by the client library (not
882 explicitly sent by application) use own command reply functions.
884 Affected files around lib/silcclient/ and in
885 irssi/src/silc/core/.
887 * Fixed the WHOIS command reply sending to chech better valid
888 clients. It was possible to send incomplete list of replies.
890 Fixed the WHOIS and IDENTIFY to send the request to router
891 if normal server did not do it and did not find any results.
893 Affected file silcd/command.c.
895 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Moved the internal data from SilcClient context into its
898 own file, not accesible to application. Affected files
899 lib/silcclient/client.h and lib/silcclient/client_internal.h,
900 and other files in client library.
902 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
904 * Added doc/examples installation target in Makefile.am.pre.
907 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
909 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
910 commands the found client entry will be removed from the
911 cache, after notifying application about the error. Affected
912 file lib/silcclient/command_reply.c.
914 * Changed the /MSG to check for exact nickname user gave, and
915 not let `nick' match `nick@host' if it is only one found. Now,
916 user must type the exact nickname (like nick@host2) even if
917 there are no more than one same nicks found. This is to avoid
918 a possibility of sending nickname to wrong nickname since
919 `nick' could match `nick@host'. Affected file is
920 irssi/src/core/silc-servers.c.
922 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
924 * Do not print "you are now server operator" or similar when
925 giving /away command. Affected files are
926 irssi/src/silc/core/client_ops.c, silc-servers.h.
928 * Made the silc_server_command_pending_error_check to send
929 the same command reply payload it received back to the
930 original sender of the command. This way all arguments
931 that was received by the server will be received by the
932 client too. Affected file silcd/command.c.
934 * Added the silc_idcache_add to return the created cache entry
935 to a pointer. Affected file lib/silccore/silcidcache.[ch].
937 * Add global clients to expire if they are not on any channel.
938 This is because normal server will never know if they signoff
939 if they are not on any channel. The cache expiry will take
940 case of these entries. This is done by normal servers only.
941 The affected files are silcd/command_reply.c,
942 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
944 * If server receives invalid ID notification for WHOIS or
945 IDENTIFY and the ID exists in the lists, it is removed.
946 Affected file silcd/command_reply.c.
948 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
949 in client then client entry that it matches is searched and
950 the nickname is printed on the screen for user. Affected
951 file irssi/src/silc/core/client_ops.c.
953 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Use cache entry expire time in the LIST command reply to
956 purge old entries from the cache after the LIST command
957 reply has been received. This way we don't have non-existent
958 entries in the cache for too long. Affected file is
959 silcd/command_reply.c.
961 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
963 * If we are normal server, and we've not resolved client info
964 in WHOIS or IDENTIFY from router, and it is global client,
965 we'll check whether it is on some channel. If it is not
966 then we cannot be sure about its validity and will resolve it
967 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
968 file silcd/command.c.
970 * Search channel by name (if possible) rather than by ID
971 in IDENTIFY command's command reply. Affected file is
972 silcd/command_reply.c.
974 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
976 * Distribute to the channel passphrase in CMODE_CHANGE notify.
977 Updated specs and implemented it. Affected file silcd/command.c,
978 silcd/packet_send.c and silcd/packet_receive.c.
980 * Implemented the <founder auth> payload handling in the JOIN
981 command. If provided all conditions for channel joining
982 except requirement to provide correct passphrase can be
983 overrided by the channel founder. Updated the protocol specs.
984 Affected file silcd/command.c.
986 Added support for founder auth in JOIN command in client
987 library. Fixed the parsing of the JOIN command now to support
988 all options as they should be. The affected file is
989 lib/silcclient/command.c.
991 * Optimized the WHOIS and IDENTIFY commands to send the request
992 to router only if it includes nicknames or other names. If
993 they include only IDs then check the local cache first before
994 routing. Affected file is silcd/command.c.
996 * Added channels topic announcements. Affected file is
997 silcd/packet_receive.c and silcd/server.c.
999 * Fixed the silc_server_send_notify_topic_set to really destine
1000 the packet to channel. Affected file silcd/packet_send.c.
1002 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1003 library. Affected file lib/silcclient/client_notify.c.
1005 * Added UMODE announcements. Affected file silcd/server.c.
1007 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Memory leak fixes in:
1011 lib/silcutil/silcsockconn.c
1012 lib/silcske/silcske.c
1013 lib/silcske/groups.c
1015 lib/silccrypt/silcpkcs.c
1016 lib/silccore/silccommand.c
1017 lib/silccore/silcidcache.c
1022 * ROBOdoc documented the lib/silcske/groups.h file and a
1023 bit changed the interface for better.
1025 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1027 * Update the client entry context in the ID cache after
1028 nick change. Affected file lib/silcclient/command.c.
1029 Fixes the CUMODE command when regaining founder privileges,
1030 and a little WHOIS problem.
1032 * Fixed silc_net_gethostbyname to correctly call the
1033 inet_ntop. Affected file lib/silcutil/silcnet.c.
1035 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1037 * Added IPv6 support checking to the configure.in.pre, added
1038 also --enable-ipv6 option to override the check. Affected
1039 file configure.in.pre.
1041 * The silc_thread_create now calls the start function
1042 directly if threads support is not compiled in. Removes
1043 ugly #ifdef's from generic code. Affected files are
1044 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1046 * Added silc_net_gethostby[name/addr]_async to asynchronously
1047 resolve. Affected files are lib/silcutil/silcnet.[ch].
1049 * Added support for rendering IPv6 based server, client and
1050 channel IDs. Affected file lib/silcutil/silcutil.c.
1052 * Added support for creating IPv6 based server IDs. Affected
1053 file is silcd/serverid.c.
1055 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1057 * Added silc_net_gethostby[addr/name] into the
1058 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1059 routines. Added silc_net_is_ip[4/6]. Affected file is
1060 lib/silcutil/unix/silcunixnet.c. All routines that take
1061 address as argument now supports both IPv4 and IPv6 addresses.
1063 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1065 * Fixed LIST command reply sending in server. Affected file
1068 * Server now sends the kicker's client ID in the KICK notify
1069 to the kicked client. Affected file silcd/command.c.
1071 * The client library now parses the kickers client ID and
1072 UI displays it. Affected files lib/silcclient/client_notify.c
1073 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1075 * Made all payload parsing function prototypes consistent.
1076 They all take now const unsigned char * and uint32 pair as
1077 the payload data instead of SilcBuffer. Changes all around
1078 the source tree. Other unsigned char* -> const unsigned char*
1079 changes around the tree as well.
1081 * Optimized SFTP client and server packet sending not to
1082 allocate new buffer for each packet but to recycle the
1083 first allocated buffer. Affected files are
1084 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1086 * Optimized the SFTP client to use SilcList instead of
1087 SilcDList for requests, because it is faster. Affected file
1088 is lib/silcsftp/sftp_client.c.
1090 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1091 into lib/silccore/silcid.[ch].
1093 Renamed silcpayload.[ch] into silcargument.[ch].
1095 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * If client entry is deleted with active key agreement
1098 session, abort the session.
1100 The silc_client_abort_key_agreement now calls the completion
1101 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1103 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1106 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Don't use __restrict in older GCC's. Affected file is
1109 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1111 * silc_net_localhost now attempts to reverse lookup the
1112 IP/hostname. Affected file lib/silcutil/silcnet.c.
1114 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1115 command. It can be used to gain founder privileges at
1116 the same time when joining the channel.
1118 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1119 kicker's client ID as well. Updated protocol specs.
1121 Defined that the server must send SILC_COMMAND_IDENTIFY
1122 command reply with error status to client who sent
1123 private message with invalid client ID.
1125 Updated the protocol specification.
1127 * Added silc_server_send_command_reply to send any
1128 command reply. Affected file silcd/packet_send.[ch].
1130 * Added silc_id_payload_encode_data to encode ID payload
1131 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1133 * The server now send IDENTIFY command reply with error
1134 status if client ID in private message is invalid. Affected
1135 file silcd/packet_receive.c.
1137 * Save the server key file with server's IP address in
1138 the filename instead of hostname. The affected file is
1139 irssi/src/silc/core/client_ops.c.
1141 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1146 * Added libtool support for compiling shared objects in
1147 lib/silcsim. Affected file configure.in.pre and
1148 lib/silcsim/Makefile.am. Original patch by cras.
1150 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Pid file configuration, and server's config file fixes
1153 patch by toma. Updated CREDITS file.
1155 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Fixed silc_client_channel_message to not try to decrypt
1158 the message twice if it resolved the destination client
1159 information. This could cause of dropping one channel
1160 message. Affected file lib/silcclient/client_channel.c.
1162 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1164 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1165 lib/silcclient/client.c. This function is used when the SILC
1166 Client is run under some other scheduler, or event loop or
1167 main loop. On GUI applications, for example this may be
1168 desired to used to run the client under the GUI application's
1169 main loop. Typically the GUI application would register an
1170 idle task that calls this function multiple times in a second
1171 to quickly process the SILC specific data.
1173 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1175 * Fixed silc_server_drop() for dropping the supplementary
1176 groups as well, this could cause a security hole on some
1179 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1181 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1184 * Write PID file after dropping privileges. Added -F option
1185 to run server on foreground. A patch by debolaz.
1186 Affected files silcd/server.c, silcd/silcd.c.
1188 * Fixed MOTD to return the MOTD file server name. Affected
1189 file silcd/command.c.
1191 * Added INFO command reply handling to the Irssi SILC Client.
1192 Affected file irssi/src/silc/core/client_ops.c.
1194 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Fixed the silc_idcache_list_* routines to really support
1197 the dynamic list. Fixes a crash. Affected file is
1198 lib/silccore/silcidcache.c.
1200 * Fixed the LIST command reply to really call LIST command's
1201 pending callbacks. Affected file silcd/command_reply.c.
1203 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Update conn->local_entry->nickname after giving NICK
1206 command. Affected file lib/silcclient/command.c.
1208 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1210 * Added the [pid] option to the silcd configuration file
1212 Affected files: serverconfig.[ch] and silcd.c
1214 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1216 * Save fingerprint in WHOIS command reply in server.
1217 Affected file silcd/command_reply.c.
1219 * Fixed NICK commands pending callback registration.
1220 Affected file lib/silcclient/command.c.
1222 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Use ++server->cmd_ident when sending commands in server,
1225 instead of random number. Affected file silcd/command.c.
1227 * Fixed GETKEY command reply to call actually GETKEY pending
1228 command callbacks. Affected file silcd/command_reply.c.
1230 * A bit stricter check for nicknames. Check for same nickname
1231 in NICK command also. Affected file silcd/command.c.
1233 * Do not call INFO command everytime client ID changes, only
1234 during first connecting. Affected file lib/silcclient/client.c.
1236 * Set the new nickname only after successful command reply for
1237 NICK command is returned by server. Affected file
1238 lib/silcclient/command.c.
1240 * Remove nicknames from nicklist during server_signoff notify.
1241 Should fix /NAMES bit more. The affected file is
1242 irssi/src/silc/core/silc-channels.c.
1244 * Added `fingerprint' field to the SilcIDListData in the
1245 silcd/idlist.h to hold the fingerprint of the client's
1248 Send the fingerprint of the client's public key in WHOIS
1251 Affected files silcd/command.c, and silcd/idlist.[ch].
1253 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1254 create fingerprint from given data.
1256 * Show the fingerprint of the client's public key in WHOIS.
1257 Affected files irssi/src/module-formats.[ch] and
1258 irssi/src/silc/core/client_ops.c.
1260 * Format the multiple same nicknames also during JOIN and
1261 NICK_CHANGE notifys. Affected file is
1262 lib/silcclient/client_notify.c.
1264 * Do not print error on screen for invalid private message
1265 payload since it can come if someone is sending private
1266 messages with wrong key. Affected file
1267 lib/silccore/silcprivate.c.
1269 * Fixed multiple concurrent /PING crash. Affected file
1270 lib/silcclient/command.c.
1272 * Changed the wrong ID encoding. All IP addresses must be
1273 in MSB first order in encoded format. They were encoded
1274 wrong and was in LSB format. Affected files are
1275 silcd/serverid.c, lib/silcutil/silcutil.c.
1277 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1279 * Call the `connect' client operation through the scheduler
1280 in case of error. Affected file lib/silcclient/client.c.
1282 * Call the `failure' client operation even if the error
1283 occurred locally during a protocol. Affected file is
1284 lib/silcclient/protocol.c.
1286 * Added support of sending LIST command to router from normal
1287 server. This way normal server can get list of all channels
1288 in the network too. Fixed the channel list sending in the
1289 server too. Affected files are silcd/command.c, and
1290 silcd/command_reply.[ch].
1292 * Added silc_server_update_channels_by_server and
1293 silc_server_remove_channels_by_server. They are used during
1294 disconnection of primary router and in backup router protocol.
1295 Affected file silcd/server_util.[ch], silcd/server.c and
1296 silcd/server_backup.c.
1298 * Fixed channel adding to global list in IDENTIFY command
1299 reply in server. Affected file silcd/command_reply.c.
1301 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * If the incoming packet type is REKEY or REKEY_DONE process
1304 that packet always synchronously. Fixes yet another MAC
1305 failed error on slow (dialup) connections. Affected file
1306 lib/silcclient/client.c and silcd/server.c.
1308 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Call check_version SKE callback for initiator too. Affected
1311 file lib/silcske/silcske.c.
1313 * Implemented fix for security hole found in the SKE that was
1314 fixed in the specification few days back; the initiator's
1315 public key is now added to the HASH value computation.
1316 Added backwards support for the old way of doing it too, for
1317 old clients and old servers. Affected file is
1318 lib/silcske/silcske.c.
1320 * Enabled mutual authentication by default in SKE. If initiator
1321 is not providing mutual authentication the responder will
1322 force it. This will provide the proof of posession of the
1323 private key for responder. The affected files are
1324 lib/silcclient/protocol.c and silcd/protocol.c.
1326 * Do not cache anymore the server's public key during SKE.
1327 We do mutual authentication so the proof of posession of
1328 private key is done, and if the server is authenticated in
1329 conn auth protocol with public key we must have the public
1330 key already. Affected file silcd/protocol.c.
1332 * Added new global debug variable: silc_debug_hexdump. If
1333 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1334 file lib/silcutil/silclog.[ch].
1336 * Fixed compilation warning due to char * -> const char *.
1337 Affected files lib/silcutil/silcnet.h, and
1338 lib/silccore/silcauth.[ch].
1340 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Fixed CMODE command when new channel key was created. If
1343 the creation failed the old key was removed. Next time giving
1344 same command would crash the server since the old key was
1345 freed already. Affected file silcd/command.c.
1347 * Fixed the silc_server_announce_get_channels to not crash
1348 on reconnect. Affected file silcd/server.c.
1350 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Added silc_log_set_debug_string function to set a regex
1353 string to match for debug output. Only the function names,
1354 or filenames matching the given debug string is actually
1355 printed. This way it is possible to filter out those debug
1356 strings that user is not interested in.
1358 Fixed a bug in silc_string_regexify.
1360 Affected files lib/silcutil/silclog.[ch], and
1361 lib/silcutil/unix/silcunixutil.c.
1363 * Changed the -d options in both server and Irssi SILC client
1364 to take the debug string as argument. Affected files
1365 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1367 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1369 * Added silc_hash_babbleprint to create a Bubble Babble
1370 Encoded fingerprint. The encoding is developed by Antti
1371 Huima (draft-huima-babble-01.txt), and it creates human
1372 readable strings out of binary data. Affected file
1373 lib/silccrypt/silchash.[ch].
1375 * Print the babble print now in addition of fingerprint as well
1376 in Irssi SILC client. Affected files are
1377 irssi/src/fe-common/silc/module-formats.[ch],
1378 irssi/src/fe-common/silc/core/client_ops.c.
1380 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1382 * Fixed a security problem found in SKE. The initiator's
1383 public key too is now added to the HASH hash value creation
1384 which is signed by the responder to create the SIGN value.
1385 This will prevent anyone in the middle to lie to the responder
1386 about the initiator's public key. If this is done now, the
1387 man in the middle will get caught. Updated the protocol
1390 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Better installation directory handling. Configure module
1393 paths and other paths automatically to example_silc* files
1394 in doc/. A patch by toma.
1396 * Fixed compiler warning from MPI library, and from SILC RNG.
1399 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1400 It can be configured with ./configure. A patch by toma.
1402 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Find correct make to use in prepare-clean. A patch by
1405 toma. Affected file prepare-clean.
1407 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1409 * Added irssi variables use_auto_addr, auto_bind_ip,
1410 auto_bind_port and auto_public_ip.
1412 * Changed the interface for silc_client_send_key_agreement
1413 in lib/silcclient/silcapi.h
1417 irssi/src/silc/core/silc-core.c
1419 lib/silcclient/silcapi.h
1420 irssi/src/silc/core/silc-channels.c
1421 lib/silcclient/client_keyagr.c
1424 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Added silc_pkcs_public_key_compare to compare two
1427 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1429 * Check that the client who set the founder mode on the
1430 channel is the same client that is giving the founder
1431 mode to itself. It is done by comparing the saved public
1432 key (it is saved even in the authentication is passphrase).
1433 Affected file silcd/command.c.
1435 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Do not process packet for disconnected socket connection.
1438 Affected file lib/silccore/silcpacket.c.
1440 * Process the DISCONNECT packet through scheduler in the
1441 client library. Affected file lib/silcclient/client.c.
1443 * Fixed the silc_client_packet_parse to not to increase
1444 the packet sequence number if the conn->sock and the
1445 current socket connection is not same. This can happen
1446 for example during key agreement when the conn includes
1447 multiple socket connections (listeners). Affected file
1448 lib/silcclient/client.c.
1450 * The sender of the file transfer request now provides also
1451 the pointer (listener) for the key exchange protocol. If
1452 the listener cannot be created then it sends empty key
1453 agreement and lets the receiver provide the listener.
1455 Added `local_ip' and `local_port' arguments to the
1456 silc_client_file_send. If they are provided they are used,
1457 if not then it will attempt to find local IP address, if
1458 not found or bind fails then the remote client will provide
1461 Affected files are lib/silcclient/client_ftp.c and
1462 lib/silcclient/silcapi.h.
1464 * Extended the FILE SEND command to support defining the
1465 local IP and port for key exchange listener. They are
1466 optional. Affected file irssi/src/silc/core/silc-servers.c.
1468 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Defined to WHOIS command reply the sending of fingerprint
1471 of the client's public key (if the proof of posession of the
1472 corresponding private key is verified by the server).
1473 Updated to the protocol specification.
1475 * Added support of receiving the client's public key's
1476 fingerprint in command reply in client library. Affected
1477 file is lib/silcclient/command_reply.c, and
1478 lib/silcclient/idlist.[ch].
1480 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Do not send over 128 chars long nickname to the server
1483 in NICK command. Affected file lib/silcclient/command.c.
1485 * Do not send over 256 chars long channel names to the server
1486 in JOIN command. Affected file lib/silcclient/command.c.
1488 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1490 * Assure that silc_server_close_connection cannot be called
1491 twice for same socket context. Affected file is
1494 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Send error message to application if opening file for
1497 writing during file transfer fails. Affected file is
1498 lib/silcclient/client_ftp.c.
1500 Remove all file transfer sessions for a client that we're
1501 removing from ID cache.
1503 Affected file is lib/silcclient/client_ftp.c.
1505 * Fixed silc_net_addr2bin to return correct address. Affected
1506 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1508 * Fixed file transfer session removing on signoff notify.
1509 Affected file irssi/src/silc/core/silc-servers.c.
1511 * Added the SilcClientFileError to be returned in the monitor
1512 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1513 Affected file lib/silcclient/silcapi.h.
1515 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Fixed a crash in silc_client_ftp_free_sessions and
1518 silc_client_ftp_session_free_client. Affected file
1519 lib/silcclient/client_ftp.c.
1521 * Added `disabled' field in the SilcChannelEntry in the server
1522 to indicate if the server entry is disabled. Affected file
1523 silcd/idlist.h, silcd/command[_reply].c.
1525 * SILC server adds now /var/run/silcd.pid everytime it is
1526 started. Affected file silcd/silcd.c.
1528 * Added silc_server_packet_send_clients to send a packet to
1529 the provided table of client entries. Affected file
1530 silcd/packet_send.[ch].
1532 * Fixed a crash in client resolving in client_prvmsg.c in
1533 client library. Affected file lib/silcclient/client_prvmsg.c.
1535 * Do not actually remove the client directly from ID cache
1536 during SERVER_SIGNOFF, but invalidate it. This way we
1537 preserve the WHOWAS info for the client. Affected file
1538 silcd/server_util.c.
1540 * Fixed SERVER_SIGNOFF notify handling in the server. The
1541 server is now able to process incoming SERVER_SIGNOFF notify
1542 for a server that it doesn't even know about. It will remove
1543 the clients provided in the notify. Affected file
1544 silcd/packet_receive.c.
1546 * Check for partial packet in data queue after every packet that
1547 was found from the queue. Return and wait for more data if
1548 there is partial data in queue. Affected file is
1549 lib/silccore/silcpacket.c.
1551 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Added SilcClietFileError enum to indicate error in
1554 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1555 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1556 Affected files lib/silcclient/silcapi.h and
1557 lib/silcclient/client_ftp.c.
1559 * Check that newsize in silc_buffer_realloc is larger than
1560 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1562 * Added better monitor of file transfers. It now monitors
1563 key agreement protocol during the file transfer too. Added
1564 error reporting too. Affected files
1565 irssi/src/silc/core/silc-servers.c,
1566 irssi/src/fe-common/silc/module-formats.[ch].
1568 * Wrote a help file for FILE command.
1570 * Added silc_rng_global_get_byte_fast to get not-so-secure
1571 random data as fast as possible. Random data is read from
1572 /dev/urandom if available and from the SILC RNG if not
1573 available. It is used in padding generation. Affected file
1574 lib/silccrypt/silcrng.[ch].
1576 * All packets in client library are now processed synchronously.
1577 Optimized packet processing a lot. Affected file
1578 lib/silcclient/client.c.
1580 * All server connection packets are processing synchronously
1581 now in server, to optimize packet processing. Affected file
1584 * Include files are installed now only in Toolkit distribution
1585 if make install is given. Affected files: all Makefile.am's.
1587 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1589 * Assure that silc_client_notify_by_server_resolve does not
1590 resolve the client information multiple times. If it cannot
1591 be found by the first it cannot be found at all. Affected
1592 file lib/silcclient/client_notify.c.
1594 * Fixed WHOWAS command reply calling. Affected file
1595 lib/silcclient/command_reply.c.
1597 * Removed all references to silc_idlist_get_client from the
1598 Irssi SILC client since that call is internal call used by
1599 the library. The Irssi SILC client will use now client
1600 retrieval functions found in silcapi.h.
1602 * Fixed a bug in resolving nickname info before sending
1603 private message. It used freed memory. Affected file
1604 irssi/src/silc/core/silc-servers.c.
1606 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1608 * Assure my_channels statistics cannot go negative in server.
1609 Affected files silcd/server.c, silcd/server_util.c.
1611 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1615 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Win32 Toolkit changes. Affected files
1618 win32/silc.dsw, win32/libsilc/libsilc.def,
1619 win32/libsilcclient/libsilc.def,
1620 lib/silcutil/silcutil.c, and
1621 lib/sftp/sftp_fs_memory.c.
1623 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Added silc_net_localip to return local host's IP address.
1626 Affected file lib/silcutil/silcnet.[ch].
1628 * If key exchange or rekey protocol is active for a connection
1629 parse all packets syncronously since there might be packets
1630 in packet queue that we are not able to process without first
1631 processing packets before them. Affected file silcd/server,
1632 lib/silcclient/client.c.
1634 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1635 whether library should continue processing the packet.
1636 Affected file lib/silccore/silcpacket.h.

1667 lib/silcutil/silcutil.[ch].
1669 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1671 * Resolve the client info when received private message or
1672 channel message for a client which nickname we don't know.
1673 Affected files lib/silcclient/client_prvmsg.c and
1674 lib/silcclient/client_channel.c.
1676 * Do not crash in /KEY if client is not connected. Affected
1677 file irssi/src/silc/core/silc-channels.c.
1679 * Added SilcClientStatus field to the SilcClientEntry in the
1680 lib/silcclient/idlist.h.
1682 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1683 is incomplete and is being resolved, it won't be resolved
1686 Make sure also that USERS command reply does not resolve
1687 twice information. Affected file is
1688 lib/silcclient/command_reply.c.
1690 Make sure that silc_client_get_clients_by_list does not
1691 resolve twice same information.
1693 * Check for valid client->id in the silc_server_free_client_data.
1694 Affected file silcd/server.c.
1696 * Fixed /GETKEY nick@server not to crash if the server entry
1697 is not found. Affected file lib/silcclient/command.c.
1699 * Fixed the silc_server_check_cmode_rights to check the
1700 requested modes correctly. Affected file silcd/command.c.
1702 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Better checks for non-printable chars in nick added.
1705 Affected file silcd/command.c.
1707 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Call the silc_server_udpate_servers_by_server in the
1710 primary router that comes back online in the backup resuming
1711 protocol. Otherwise it routes packets wrong. Affected file
1712 silcd/server_util.[ch], silcd/server_backup.c.
1714 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1717 lib/silcutil/silcbuffmt.[ch].
1719 * Redefined the SILC packet header to include the padding
1720 length. Affected file lib/silccore/silcpacket.[ch].
1722 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1723 length for maximum padding up to 128 bytes). Affected
1724 file lib/silccore/silcpacket.h.
1726 * Removed all backwards support for old 0.5.x MAC thingies.
1727 The SILC packet header change makes it impossible to be
1728 backwards compatible.
1730 * Send the ENDING packet with timeout in the backup resuming
1731 protocol. This is to assure that all routers has connected
1732 to the primary router. Affected file silcd/server_backup.c.
1734 * Changed the RNG to take the first IV from random data. It
1735 used to take it from zero actually. Changed the RNG also
1736 to use /dev/urandom during session. /dev/random is used
1737 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1739 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Changed the SILC packet header to have the first two bytes
1742 (the packet length) encrypted. Affected files aroung the
1743 code tree, lib/silccore/silcpacket.[ch]. Removed the
1744 SilcPacketCheckDecrypt callback. It is not needed anymore
1745 since the silc_packet_receive_process will determine now
1746 whether the packet is normal or special.
1748 * Implemented the unidirectional MAC keys. Affected files
1749 lib/silcske/silcske.c, silcd/protocol.c and
1750 lib/silcclient/protocol.c.
1752 * Implemented the packet sequence number to the MAC computation.
1753 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1754 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1755 lib/silcclient/protocol.c.
1757 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1759 * Allow backup router to announce servers. All servers
1760 announced by backup router are added to the global list
1761 automatically. Update hte server's socket to our primary
1762 router also when backup router announces a server.
1763 Affected file silcd/packet_receive.c.
1765 * Do not update the client->router in the function
1766 silc_server_udpate_clients_by_server if the client is on
1767 global list. We might fail to find any specific server
1768 for locally connected clients and local cell clients. They
1769 should still use the `from' and not `to' as client->router.
1770 This fixes backup router resuming protocol. Affected file
1771 silcd/server_util.c.
1773 * Decrease channel statistics count only if the channel
1774 deletion worked. Affected files are silcd/server.c and
1775 silcd/server_util.c.
1777 * Added silc_server_update_servers_by_server to update origin
1778 of all server entries. Used during backup router protocol.
1779 Affected files silcd/server_util.[ch], silcd/server.c. and
1780 silcd/backup_router.c.
1782 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1783 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1784 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1785 lib/silccrypt/silchmac.c.
1787 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1789 * Assure that router cannot reroute the same channel message
1790 to the sender. Affected file silcd/packet_receive.c.
1792 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Made better checks that the channel message is not sent
1795 to the router it came from. Affected file is
1796 silcd/packet_send.c. Fixed memory leak too.
1798 * Announce informations for incoming router connection, but
1799 only after checking if it is replaced by backup router.
1800 Affected file silcd/packet_receive.c.
1802 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Fixed the backup resuming protocol to work in multiple
1805 router environment. Affected file silcd/server_backup.c.
1807 * Route packet only to one router in the function
1808 silc_server_packet_send_to_channel. Affected file is
1809 silcd/packet_send.c.
1811 * Fixed silc_server_send_notify_dest to set the broadcast
1812 flag. Fixed the silc_server_send_notify_topic to actually
1813 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1814 Affected file silcd/packet_send.c.
1816 * Changed the SFTP Filesystem interface. Changed the
1817 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1818 the filesystem operation function. The SilcSFTPFilesystem
1819 is now a context that is allocated by all filesystem allocation
1820 functions and it already includes the operations structure
1821 and filesystem specific context. It is given as argument
1822 now to the silc_sftp_server_start. This made the interface
1823 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1824 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1826 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * Changed the backup router adding and getting interfaces
1829 in the server. The router that will be replaced by the
1830 specified backup router is now sent as argument. Affected
1831 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1834 * Added silc_net_addr2bin_ne to return the binary form of
1835 the IP address in network byte order. Affected files
1836 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1838 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Check for existing server ID in silc_server_new_server
1841 and in silc_server_connect_to_router_final and remove the
1842 old entry if it exists. Affected file silcd/packet_receive.c,
1845 * Send the channel message always to only one router, either
1846 in upstream or downstream. Affected file is
1847 silcd/packet_send.c.
1849 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Wrote the definition of the backup resuming protocol to the
1852 protocol specification.
1854 * Removed one redundant channel key generation from normal
1855 server during joining procedure. Removed one redundant
1856 channel key sending from server to router during joining
1857 procedure. Affected file silcd/command.c.
1859 * Made minor bugfixes to the backup router resuming protocol.
1860 Affected file silcd/server_backup.c, server.c.
1862 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Added --disable-asm configuration option. Affected files
1865 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1868 * Implemented the backup resuming protocol that is used to
1869 resume the primary router position in the cell after the
1870 primary router comes back online. Affected files
1871 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1872 and silcd/server_util.[ch].
1874 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Sleep two (2) seconds after sending QUIT command to server.
1877 Affected file lib/silcclient/command.c.
1879 * Assure that if outgoing data buffer is pending do not force
1880 send any data. Affected file silcd/packet_send.c.
1882 * Assure that if outgoing data buffer is pending do not force
1883 send any data. Affected file lib/silcclient/client.c.
1885 * Implemented the backup router support when the primary router
1886 goes down. The servers and routers can now use the backup
1887 router as new primary router without loosing connectivity.
1889 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1891 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1892 in the server to indicate disabled entry. All data read
1893 from the connection will be ignored and no data is sent
1894 for entry that is disabled. Affected files are
1895 silcd/idlist.h, silcd/server.c.
1897 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Created SFTP client and server test programs in the
1900 lib/silcsftp/tests directory.
1902 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Implemented memory filesystem (virtual filesystem) for
1905 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1908 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Implemented the SFTP (SSH File Transfer Protocol) to the
1911 lib/silcsftp. It includes SFTP client and SFTP server
1914 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Moved lib/silccore/silcprotocol.[ch] to the
1917 lib/silcutil library.
1919 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1920 take variable argument list pointer as argument. Affected
1921 file lib/silcutil/silcbuffmt.[ch].
1923 * Added silc_buffer_set function that is used to set data
1924 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1925 Affected file lib/silcutil/silcbuffer.h.
1927 * Changed various routines in the core library to use the new
1928 silc_buffer_set instead of allocating new buffer only for
1931 * Added 64-bit value formatting and unformatting support to the
1932 silc_buffer_[un]format routines. Affected file is
1933 lib/silcutil/silcbuffmt.[ch].
1935 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1936 to includes/bitmove.h.
1938 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Fixed channel user mode saving in client library. Affected
1941 file lib/silcclient/command[_reply].c.
1943 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Defined the file transfer to the SILC Protocol. Added
1946 new packet type SILC_PACKET_FTP and defined File Transfer
1947 Payload. The mandatory file transfer protocol is SFTP
1948 (SSH File Transfer Protocol). Affected file in addition
1949 of the internet draft is lib/silccore/silcpacket.h.
1951 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1952 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1953 is used as part of backup router protocol when the primary
1954 router of the cell is back online and wishes to resume
1955 the position as primary router.
1957 * Redefined the MAC generation keys in the protocol. The
1958 same key is not used anymore in both direction. Both
1959 direction will now use different keys for sending and
1960 receiving. This fixes a potential security flaw. This
1961 change causes incompatibilities in the protocol.
1963 * Redefined also the MAC computation from the packet.
1964 An packet sequence number is now added to the MAC
1965 computation. This prevents possible replay attacks against
1966 the protocol. This change too causes incompatibilities
1969 Added `sequence' field to the SilcPacketContext to hold
1970 the current sequence number for the packet.
1972 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Added `created' field to the SilcIDListData in the file
1975 silcd/idlist.h to indicate the time when the entry was
1978 * Added `created' field to the SilcChannelEntry too. Affected
1979 file silcd/idlist.h.
1981 * Added `creation_time' aguments to all the announcement functions
1982 in the server. If it is provided then only the entries that
1983 was created after the provided time frame are actually
1984 announced. Affected file silcd/server.[ch].
1986 * The protocol says that the Channel ID's IP address must be
1987 based on the router's IP address. Added check for this in
1988 the silc_server_new_channel when processing incoming New Channel
1989 Payload. Affected file silcd/packet_receive.c.
1991 * Print out the correct version with --version in SILC client.
1992 Affected file irssi/src/silc/core/silc-core.c.
1994 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Fixed WHOWAS command to check for completnes of the client
1997 entry always, not just when the command is coming from client.
1998 Affected file silcd/command.c.
2000 * Added new function silc_server_packet_queue_purge to purge the
2001 outgoing data queue to the network. After the function returns
2002 it is guaranteed that the outgoing packet queue is empty.
2003 Affected file silcd/packet_send.[ch].
2005 * Purge the outgoing packet queue in the rekey protocol's final
2006 callback to assure that all rekey packets go to the network
2007 before quitting the protocol. Affected file silcd/server.c.
2009 * Added silc_client_packet_queue_parse as similar function as
2010 in server to the client library. The affected file is
2011 lib/silcclient/client.c.
2013 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Splitted silcd/server.c and created silcd/server_util.[ch]
2016 for utility functions.
2018 * Added new socket flag SILC_SF_DISABLED to indicate that the
2019 connection is open but nothing can be sent to or received from
2020 the connection. Affected file lib/silcutil/silsockconn.[ch].
2021 The checking for disabled socket is checked in the low level
2022 silc_socket_write and silc_socket_read functions.
2024 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Allow only nicknames and channel names that fits into the
2027 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2029 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * When processing JOIN command reply in server check that if
2032 the channel exists in our global list we'll move it the local
2033 list. Affected file silcd/command_reply.c.
2035 * Fixed the check whether client is joined on the channel already
2036 in JOIN command. Affected file lib/silcclient/command.c.
2038 * Fixed the JOIN command reply to check whether the channel
2039 already exists. Affected file lib/silcclient/command_reply.c.
2041 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Added silc_ske_status_string to map the SKE error numbers
2044 to readable strings. The affected files are
2045 lib/silcske/silcske[_status].[ch].
2047 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Do not show the private channels on the WHOIS channel list
2050 as it is not allowed by the protocol. The affected file is
2053 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Assure that the packet length digged from the actual packet
2056 is something sensible in the silc_packet_decrypt_rest_special
2057 in lib/silccrypt/silcpacket.c.
2059 * Free and NULL the allocated pointer in silc_hmac_alloc if
2060 the HMAC allocation fails. The affected file is
2061 lib/silccrypt/silchmac.c.
2063 * Print the selected security properties to the log files in
2064 the server. Affected file silcd/protocol.c.
2066 * Add SKE's reference counter even if calling the completion
2067 callback manually. Otherwise it goes negative, although it
2068 does not cause any problems. The affected file is
2069 lib/silcske/silcske.c.
2071 * Remove the client entry with short timeout after giving the
2072 KILL command. Affected file lib/silcclient/command.c.
2074 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2075 case all found clients are already disconnected (WHOWAS would
2076 found them) in the server. Affected file silcd/command.c.
2078 * Update the last_receive (time of last data received) to be
2079 updated only when received private or channel message so that
2080 the idle time showed in WHOIS makes more sense.
2082 * Added boolean field `valid' in to the SilcClientEntry in the
2083 client library to indicate whether the entry is valid or not.
2084 This fixes the nickname change bug on channel when changing
2085 the nickname to be same than the old (like nick to Nick) the
2086 nickname formatter doesn't set the new nick anymore to Nick@host.
2087 Affected file lib/silcclient/idlist.[ch].
2089 * Now actually fixed the nickname changing on disconnection.
2090 Added new function silc_change_nick to the Irssi SILC Client.
2091 Affected file irssi/src/silc/core/client_ops.c,
2092 irssi/src/silc/core/silc-nicklist.[ch].
2094 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Check that the public key exists in the GETKEY command before
2097 trying to encode it. Affected file silcd/command.c.
2099 * Print some notifications on received public keys with GETKEY
2100 command in the Irssi SILC Client. Affected files are
2101 irssi/src/fe-common/silc/module-formats.[ch],
2102 irssi/src/silc/core/client_ops.c.
2104 * Use IDENTIFY command to resolve the server information in the
2105 GETKEY command instead of INFO command. Affected file
2106 lib/silcclient/command.c.
2108 * All command reply functions in the client library now calls
2109 the pending command reply callbacks even if an error has
2110 occurred. The server has done this a long time and now it was
2111 time to move the client library to this as well. Now all
2112 errors can be delivered back to the pending command reply
2113 callbacks if necessary. Affected files are
2114 lib/silcclient/command[_reply].[ch].
2116 * Change the nickname on disconnection back to the username
2117 because in reconnect the server will enforce it to it anyway.
2118 Affected file irssi/src/silc/core/silc-servers.c.
2120 * Fixed a config file parsing bug in the Irssi SILC client.
2121 Affected file irssi/src/silc/core/clientconfig.c.
2123 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * When printing the channel mode on JOIN, verify that the
2126 channel key and channel's HMAC are valid. Affected file
2127 irssi/src/silc/core/client_ops.c.
2129 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2132 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2133 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2135 * Removed channel key rekey task deleting from the function
2136 silc_server_save_channel_key. Affected file silcd/server.c.
2137 Added explicit timeout task context instead that is used to
2138 delete the task if we are registering a new task before the
2139 new task has elapsed.
2141 * When channel key rekey occurs the client library now saves
2142 the old channel key for a short period of time (10 seconds) and
2143 is able to use it in case some is still sending channel
2144 messages encrypted with the old key after the rekey. Affected
2145 file lib/silcclient/[idlist.h|client_channel.c].
2147 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Added check to the silc_server_new_id_real to not accept
2150 new ID if it is the sender's own ID. Affected file is
2151 silcd/packet_receive.c.
2153 * Assure that we do not announce ourself or the one we've
2154 sending our announcements when we're router and are announcing
2155 servers to our primary router. Affected file silcd/server.c.
2157 * Fixed silc_server_command_identify_check_client to assemble
2158 correct WHOIS packet. It send corrupted WHOIS packet and
2159 caused problem with router to router connections. Affected
2160 file silcd/command.c.
2162 Fixed also silc_server_command_whois_check the same way
2163 as for the IDENTIFY command.
2165 * Added new SilcIDListStatus to the server in the SilcIDListData
2166 structure. The status now includes the current status of
2167 the entry (like registered, resolved etc.). Affected file
2168 silcd/idlist.[ch]. Defined a bunch of different status types
2169 as well. This replaced the old boolean registered field as well.
2171 Added resolve_cmd_ident field to the SilcClientEntry structure
2172 too so that if the entry is for example being resolved so
2173 another command may attach to the same pending command reply
2174 without requiring to resolve the same entry again. This concept
2175 should optimize the WHOIS and the IDENTIFY resolving under
2176 heavy load by taking away unnecessary resolving for entries
2177 that are being resolved already.
2179 Added support for adding multiple pending commands for one
2180 command idenfier. Affected file silcd/command[_reply].[ch].
2182 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2183 before deleting the data. Otherwise the hash table will have
2184 freed data in comparison functions. Affected file is
2185 silcd/command_reply.c.
2187 * Fixed silc_idlist_replace_client_id to add the new entry to
2188 the cache with NULL nickname. Otherwise there will be invalid
2189 memory as the nickname after the nickname is freed. Affected
2190 file silcd/packet_receive.c.
2192 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2193 saved into wrong slots because the previous number of entries
2194 was not taken into account. Affected file silcd/idlist.c.
2195 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2197 * If we are router and we receive JOIN notify to a channel that
2198 does not have any users then notified client is marked as the
2199 channel founder, as it is it. The affected file is
2200 silcd/packet_receive.c
2202 * Added to the extended hash table API's table_del_*ext functions
2203 the destructor as argument too, so that the caller can decide
2204 which destructor to use or whether to use destructor at all.
2205 Affected file lib/silcutil/silchashtable.[ch].
2207 * Fixed ID Cache purging. It actually deleted the entries from
2208 the hash table after the data was freed. The hash table ended
2209 up comparing freed memory. The affected file is
2210 lib/silccore/silcidcache.c.
2212 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Fixed Irssi SILC client's KILL command's HELP syntax.
2216 * The USERS command now resolves the detailed user information
2217 if the userinfo field is missing. Affected file is
2218 lib/silcclient/command_reply.c.
2220 * Do not print error in silc_file_read if the read file does
2221 not exist. Just silently return NULL. Affected file is
2222 lib/silcutil/silcutil.c.
2224 * Fixed the silc_log_output to not wine about NULL filename
2225 and to not create some bogus " " filename. Affected file is
2226 lib/silcutil/silclog.c.
2228 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Fixed various printing bugs on the user interface in the
2231 Irssi SILC Client. Minor changes that were forgotten from
2234 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Fixed the configure.in.pre and the compilation and distribution
2237 environment to support the new autoconf 2.52. That version is
2238 now required to compile the CVS trunk.
2240 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2243 to generally parse user@fqdn format strings. Affected file
2244 lib/silcutil/silcutil.c.
2246 * Added nickname_format and nickname_force_format fields to the
2247 SilcClientParams structure. The first one defines the format
2248 for the nicknames that the library will enforce if the receives
2249 multiple same nicknames. The second one is boolean value and
2250 can be used to force the library to always enforce the format
2251 to the nicknames regardles whether there are multiple nicknames
2252 or not. This configurable formatting was employed to flexibly
2253 support accessing multiple nicknames from the user interface.
2254 The userinterface can now set the nicknames to what ever format
2255 they prefer. Affected file lib/silcclient/silcapi.h.
2257 Added function silc_client_nickname_format to the file
2258 lib/silcclient/idlist.c. It performs the nickname formatting.
2260 Added new field `hostname´ to the SilcClientEntry context.
2261 It holds the hostname of the client. Affected file is
2262 lib/silcclient/idlist.h.
2264 * Irssi SILC Client sets the nicknames in nick@hostn format.
2265 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2266 irssi/src/silc/core/silc-core.c.
2268 The WHOIS printing now also shows both the real nickname and
2269 the formatted nickname so that user knows how to access the
2270 user if there are multiple same nicknames cached. Affected
2271 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2272 printing formatting too to take the hostname now as a separate
2273 argument. The Affected file is
2274 irssi/src/fe-common/silc/modules-formats.[ch].
2276 * Changed the silc_client_get_clients_local to accept the formatted
2277 nickname as argument. It accepts the real nickname too but the
2278 formatted nickname can be used to find the true entry from
2279 multiple entries. Affected file lib/silcclient/silcapi.h and
2280 lib/silcclient/idlist.c.
2282 * Added nickname_format_parse field to the SilcClientParams.
2283 It is a callback function provided by the application to parse
2284 the nickname out of the formatted nickname string. The library
2285 calls it to get the nickname from the formatted string. Since
2286 the application generally knows better the format of the nickname
2287 string it parses it instead of the library, even though library
2288 encodes the formatted string. If the callback function is not
2289 provided then the library will use the string as is. The
2290 affected file is lib/silcclient/silcapi.h.
2292 * All the nickname strings passed to the client library in
2293 commands are now expected to be formatted nickname strings.
2294 If the command does not support the formatted nickname string
2295 it will assume that the sent string is the actual nickname.
2296 Affected file lib/silcclient/command.c.
2298 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Added public key authentication support to OPER and SILCOPER
2301 commands in the client library. Affected file is
2302 lib/silcclient/command.c.
2304 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Changed the get_auth_methdod client operation to be asynchronous.
2307 It can be async if the application resolves the authentication
2308 method from the server during the negotiation. Added new
2309 SilcGetAuthMeth completion callback that the application will
2310 call after resolving the authentication method.
2312 Added function silc_client_request_authentication_method that
2313 the application can use to resolve the authentication method
2314 from the server. Added also SilcConnectionAuthRequest callback
2315 that the library will call after the server has replied. The
2316 application can call this function if it does not know the
2317 current authentication method.
2319 Affected files are lib/silcclient/client.c and
2320 lib/silcclient/silcapi.h.
2322 * The Irssi SILC client now automatically resolves the authentication
2323 method incase any configuration information is not present (and
2324 currently there never is). The affected file is
2325 irssi/src/silc/core/client_ops.c.
2327 * Fixed public key authentication from the client library.
2328 Affected file lib/silcclient/protocol.c. Changed also the
2329 protocol specification about the public key authentication in
2330 the connection authentication protocol. The actual data to be
2331 signed is now computed with a hash function before signing.
2333 * Fixed the public key authentication from the server as well.
2334 Affected file silcd/protocol.c.
2336 * Removed the mlock()'s from the memory allocation routines.
2337 Affected file lib/silcutil/silcmemory.c. The ./configure does
2338 not check anymore for the mlock(). Affected file is
2341 * Fixed USERS command in server to allow the execution of the
2342 command for private and secret channels if the client sending
2343 the command is on the channel. Affected file silcd/command.c.
2345 * Fixed silc_client_get_clients_local to return the clients
2346 count correctly. It could return wrong value. Affected file
2347 lib/silcclient/idlist.c.
2349 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2351 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2352 types. The assembler optimizations seemed not to like 64-bit
2353 data types. The assmebler optimizations thus are now enabled
2354 also for BSD systems as opposed to only enable them for Linux.
2356 * Do not check for threads at all on BSD systems. Affected
2357 file configure.in.pre.
2359 * Removed -n and -h options from the Irssi SILC Client since
2360 they are not used in silc.
2362 * Fixed the prime generation to assure that the first digit
2363 of the generated random number is not zero since our conversion
2364 routines does not like number strings that starts with zero
2365 digit. If zero digit is seen the random number is regenerated.
2366 This caused some corrupted RSA keys when the zero first digit
2367 was met. Affected file lib/silcmath/silcprimegen.c.
2369 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Fixed WIN32 configuration in the ./configure script.
2372 Fixed to include xti.h on environments that has it.
2373 Patches by Carsten Ilchmann and andrew.
2375 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Changed the silc_id_create_client_id to be collision
2378 resistant. It is now assured that there cannot be created
2379 two same client ID's. I suspect that some weird bugs in
2380 the server were actually caused by duplicate Client IDs.
2381 Affected file silcd/serverid.[ch]. A router receiving
2382 new ID now also assures and informs the sending server
2383 if the ID caused collision.
2385 * Changed the silc_id_create_channel_id to also assure that
2386 there are no collisions.
2388 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Statement about ignoring the Mutual Authentication flag when
2391 performing rekey with PFS was a bit misleading. It is ignored
2392 if it was set in the initial negotiation, it cannot be even
2393 set in the rekey. Fixed in the ke-auth draft. Started the
2394 new versions of the protocol drafts in the doc/.
2396 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Fixed a bug in silc_client_command_identify_save when saving
2399 new channel information. The channel name was no duplicated
2400 and caused crash on exit. Affected file is
2401 lib/silcclient/command_reply.c.
2403 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Fixed the getkey command handling in the server. Send just
2406 empty OK reply to the sender if the key could not be fetched
2407 (but everything else was ok, like the key just was not available).
2408 Changed the public key parameter to optional in the protocol
2409 specs so that empty OK reply can be sent. Affected file
2412 Added a message to Irssi SILC client to tell to user if the
2413 server did not return a public key.
2415 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Fixed a channel key regeneration bug. It registered new
2418 timeout tasks exponentially until all system resources were
2419 used. Affected file silcd/server.c.
2421 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Added the SILC Document generator to the scripts/silcdoc.
2424 It can be used to generate the Toolkit Reference Manual out
2425 of the source tree. Internally it will also use the RoboDoc
2426 generator now imported in util/robodoc.
2428 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Added couple of return's in rekey protocol if error orccurred
2431 during the protocol. The execution must be terminated.
2432 Affected file silcd/protocol.c. Also, terminate the protocol
2433 always with timeout.
2435 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * The client's Client ID was created initally from the wrong
2438 nickname (it could have been in format nick@host) in the
2439 silc_server_new_client. Affected file silcd/packet_receive.c
2441 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Added some SILC_LOG_ERROR's to various error conditions
2444 if client could not be added to ID cache. Affected files
2445 silcd/packet_receive.c and silcd/server.c.
2447 * When client's sock->user_data is freed, NULL also the
2448 client->router and client->connection pointers. Added check
2449 for these pointers being NULL to various places around the
2450 code. Affected file silcd/server.c.
2452 * Added client->data.registered == TRUE checks to various
2453 places around the code to assure that unregistered client's
2454 are not handled when it is not allowed. Affected file
2457 * Added `bool registered' fields to all
2458 silc_idlist_[server|client]_get_* routines to indicate whether
2459 the fetched client needs to be registered or not. Affected
2460 file silcd/idlist.[ch].
2462 * Add your own entry as registered to the ID cache in the
2463 server. Affected file server.c.
2465 * Fixed a bug in silc_server_new_server. The SilcServer was
2466 set as the new server's context instead of SilcServerEntry.
2467 This naturally caused some weird bugs.
2469 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Do not delete the channel rekey task when adding it
2472 for in silc_server_create_channel_key.
2474 * Changed the silc_server_create_channel_key to return
2475 TRUE or FALSE to indicate the success of the channel key
2478 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Fixed MSVC++ project files and added missing files to
2481 Makefiles under win32/.
2483 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Do not add TCP_NODELAY flag if the operating system
2486 does not have it defined. Affected files are
2487 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2489 * Fixed buffer overflow from Irssi SILC Client. Affected
2490 file irssi/src/fe-common/core/themes.c.
2492 * Fixed double free in client library in the file
2493 lib/silcclient/client.c when disconnecting from server.
2495 * Applied double free patch from cras to Irssi SILC client.
2496 Affected files irssi/src/core/[modules/expandos].c
2498 * Fixed the disconnection handling to Irssi SILC Client.
2499 The application must call silc_client_close_connection
2500 in ops->connect client operation in case of failure of
2501 the connection. Affected file is
2502 irssi/src/silc/core/client_ops.c.
2504 * Do not set sock->protocol to NULL in the function
2505 silc_client_close_connection after executing the protocol's
2506 final callback since the sock might not be valid anymore.
2507 Affected file lib/silcclient/client.c.
2509 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Do not enable SILC_THREADS if the linking with libpthread
2512 did not happen. Affected file configure.in.pre.
2514 * Added notion to protocol specification that server must
2515 verify the sent authentication payload with CMODE when
2516 setting the channel founder key. Implemented it to the
2517 server. Affected file silcd/command.c.
2519 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2521 * Added _EXTRA_DIST SILC distribution variable to the
2522 distributions file. It is used to conditionally add extra
2523 files or directories to the specific distribution. Affected
2524 files ./prepare, Makefile.am.pre and distributions.
2526 Removed the `_' from the start of the distribution names.
2529 * Added README.WIN32 for instructions to compile the Toolkit
2532 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Fixed a double free in disconnection in the server. Affected
2535 file is silcd/server.c.
2537 * Fixed the lib/silcske/groups.c to work now also with GMP
2538 MP library. The string conversion did not work when using
2539 specific base and the base is indicated in the string as well.
2541 * Created win32/ directory which now includes MSVC++ specific
2542 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2543 It will appear only in the toolkit distribution
2545 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Changed the key material distribution function in case when
2548 the hash output is too short. The data is now concatenated
2549 a bit differently than it used to. Made the change to the
2550 SKE protocol specification.
2552 * Added better GMP detection to configure.in.pre. A patch
2555 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2557 * Fixed a minor bug in SKE that might cause some problem on
2558 some platforms. Affected file lib/silcske/silcske.c.
2560 * Added the cookie checking for initiator in the SKE. It checks
2561 that the responder returns the sent cookie unmodified. The
2562 affected file is lib/silcske/silcske.c. Added new SKE
2563 error type INVALID_COOKIE that can be sent during the
2564 negotiation. Fixed some memory leaks as well.
2566 * Added the "invalid cookie" error message to Irssi SILC client's
2569 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Added `task_max' field to the SilcClientParams to indicate
2572 the maximum tasks the scheduler can handle. If set to zero,
2573 default values are used. Affected file lib/silcclient/silcapi.h.
2575 * Fixed memory leaks in silc_client_close_connection. Affected
2576 file lib/silcclient/client.c.
2578 * Added silc_client_del_client_entry to client library to free
2579 all memory of given client entry. Affected file is
2580 lib/silcclient/idlist.[ch].
2582 * Added new functions silc_client_del_channel and
2583 silc_client_del_server to delete channel and server entries.
2584 Affected file lib/silcclient/[silcapi.h/idlist.c].
2586 * Removed silc_client_del_client_by_id from silcapi.h.
2588 * Fixed the INFO command to return the server's own info
2589 correctly when querying by Server ID. Affected file is
2592 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Removed the non-blocking settings in WIN32 code in the
2595 silc_sock_[read/write] and added SleepEx instead. Affected
2596 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2597 of input data is now checked with FIONREAD and ioctlsocket.
2599 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Call silc_schedule_task_del_by_context in the
2602 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2603 Affected file lib/silccore/silcprotocol.c.
2605 * Call silc_protocol_cancel for active protocols in the
2606 silc_server_close_connection if the funtion
2607 silc_server_free_sock_user_data has not been called.
2608 Affected file silcd/server.c.
2610 * Generic tasks cannot be deleted using the del_by_fd
2611 task deleting function since generic tasks does not match
2612 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2614 * Added a notion to SILCOPER help file that the SILCOPER works
2615 only on router server, not on normal server.
2617 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2619 * Added for WIN32 support for the new scheduler as well.
2620 Affected file lib/silcutil/win32/silcwin32schedule.c.
2622 * Fixed the SHA1 implementation to work on various platforms.
2624 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2627 API. It is part of the scheduler now. Everything else is
2628 as previously but some functions has changed their names.
2629 Checkout the lib/silcutil/silcschedule.h for the interface.
2630 Updated all applications to use the new interface. Affected
2631 files are lib/silcutil/silcschedule.[ch].
2633 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * Found a bug in the SKE implementation. The HASH value,
2636 specified by the protocol, was not computed correctly. The
2637 public key of the responder was not added to the computation
2638 even though it is mandatory. Affected file lib/silcske/silcske.c.
2639 This unfortunately causes incompatibilities with older
2640 clients and servers.
2642 * Added WIN32 specific network init and uninit functions:
2643 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2644 the Winsock2. Affected file lib/silcutil/silcnet.h and
2645 lib/silcutil/win32/silcwin32net.c.
2647 * Set the socket always to nonblocking mode on WIN32 after
2648 reading data or writing data. Affected file is
2649 lib/silcutil/win32/silcwin32sockconn.c.
2651 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Fixed various compilation problems under WIN32. Affected
2654 files lib/silcutil/win32/silcwin32thread.c and
2655 lib/silcutil/win32/silcwin32schedule.c.
2657 * Removed all _internal.h #includes from public header
2658 files. Internal headers must never be included from
2661 Removed also the lib/silcske/payload_internal.h file.
2663 * All include files that may be needed (public and some others
2664 included by the public headers) by application developers are
2665 now copied to the ./includes directory. It does not copy any
2666 internal headers. Affected file Makefile.defines.pre and all
2667 Makefile.am's under lib/ and subdirs.
2669 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Do not change the ~/.silc directory's permissions automatically.
2672 Affected file irssi/src/silc/core/clientutil.c.
2674 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2676 * Do not cancel the protocol in silc_server_close_connection
2677 it might cause recursion. Now cancelled in the function
2678 silc_server_free_sock_user_data. Affected file silcd/server.c.
2680 * Fixed the silc_server_remove_clients_by_server to regenerate
2681 the channel keys correctly finally. Added also new function
2682 silc_server_remove_clients_channels to actually do it.
2683 Affected file silcd/server.c.
2685 * Fixed the silc_server_new_channel to not crash by giving
2686 wrong router to the new channel. Affected file is
2687 silcd/packet_receive.c.
2689 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2692 which is given as argument to the silc_client_alloc now.
2693 It can be used to configure the client and set various parameters
2694 that affect the function of the client.
2696 * The USERS command in server did not check whether the channel
2697 is private or secret. Affected file silcd/command.c.
2699 * Added new argument to the USERS command in protocol specification.
2700 The USERS command now can take the channel name as argument
2701 as well. Added support for this in client and server and
2702 updated the protocol specs.
2704 * Completed the GETKEY command in client. It can be now used
2705 to fetch also servers public key not only some clients.
2706 Affected files lib/silcclient/command[_reply].c.
2708 * Added silc_client_get_server to return server entry by the
2709 server name. Affected files lib/silcclient/silcapi.h and
2712 * Redefined the IDENTIFY command in protocol specification to be
2713 more generic. It now can be used to query information about
2714 any entity in the SILC Network, including clients, servers and
2715 channels. The query may be based either the entity's name
2716 or the ID. Added support for this in both client and server.
2718 Affected files silcd/command.c and lib/silcclient/command.c
2719 and command_reply.c.
2721 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2722 the _from_client and _from_server functions. Affected file
2725 * Added silc_client_get_channel_by_id_resolve to the file
2726 lib/silcclient/silcapi.h to resolve channel information by
2727 its ID. Added also silc_client_get_channel_by_id that
2728 does not resolve it from the server.
2730 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Added SilcServerEntry context into the client library
2733 to represent one server. The INFO command now allocates
2734 these to save the resolved server info. For now on the
2735 client library will also keep information about servers,
2736 connected and resolved with INFO.
2738 The INFO command now allocates the SilcServerEntry context
2739 and saves the server info there. The COMMAND_REPLY in
2740 the INFO now returns the parameters to application in
2741 same order as defined in the protocol specification.
2743 The entries are cached in the client->server_cache.
2745 * The INFO command is now issued after received the Client ID
2746 from the server. Affected file lib/silcclient/client.c.
2748 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2749 to the application as the mode changer might be server.
2750 It is guaranteed that NULL is not returned anymore to the
2751 application. Affected file lib/silcclient/client_notify.c.
2753 The ID Type is now also passed to the application so that
2754 it can check whether the returned entry is SilcClientEntry
2757 Added new function silc_client_get_server_by_id to return
2758 the server entry by ID. Affected files are the
2759 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2761 * Do not create the channel in the Irssi SILC Client when issuing
2762 the JOIN command but when received the sucessful JOIN command
2763 reply. Otherwise the channel might get created even though we
2764 could not join it. The Affected file is
2765 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2767 * Fixed a channel joining bug in router. The router must also
2768 check the channel modes, invite and ban lists etc. when serving
2769 the JOIN command sent by normal server. Affected file is
2770 silcd/command.c. The router now resolves the client's
2771 information from the server who sent the JOIN command if it
2772 does not know it, and processes the JOIN command only after
2775 * Changed the SilcCommandCb to take new argument; void *context2.
2776 Affected file lib/silccore/silccommand.h
2778 The second argument in the command callbacks in the server now
2779 includes the SilcServerCommandReplyContext if the command was
2780 called as pending command callback from the command reply.
2781 Otherwise it is NULL. When called as pending the status of the
2782 command reply will be checked and if it was erronous the
2783 error will be sent to the original sender of the command.
2784 This way the client always receives the error messages even
2785 though the server was actually the one who received the error
2786 when it resent the command to router, for example. Affected
2787 files silcd/command[_reply].[ch].
2789 * Fixed sending WHOWAS command's error message to client if
2790 the requested client could not be found. It was missing.
2793 * Changed the CMODE and CUMODE commands reply arguments in the
2794 protocol specification. The Channel ID is now sent in both
2795 of the commands to identify the channel. Implemented this
2796 new feature to the client and server. Affected files
2797 lib/silcclient/command_reply.c and silcd/command.c.
2799 * Made better checks for invite and ban lists in the JOIN
2800 command in server. Affected file silcd/command.c.
2802 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2804 * The server now performs the incoming host IP/DNS lookup
2805 using the silc_socket_host_lookup and thus does not block
2806 the server anymore. Affected file silcd/server.c.
2808 * Completed the multi-thread support for SILC Scheduler in
2809 the lib/silcutil/silcschedule.c.
2811 * Fixed the configure.in.pre to detect the pthread correctly
2814 * Fixed a deadlock in silc_task_queue_wakeup in the file
2815 lib/silcutil/silctask.c.
2817 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Added new function silc_schedule_wakeup that is used in
2820 multi-threaded environment to wakeup the main thread's
2821 schduler. It needs to be used when a thread adds a new task
2822 or removes a task from task queues. After waking up, the
2823 scheduler will detect the task queue changes. If threads
2824 support is not compiled in this function has no effect.
2825 Implemented the wakeup mechanism to both Unix and WIN32
2826 systems. Affected files are lib/silcutil/silcschedule.[ch],
2827 lib/silcutil/unix/silcunixschedule.c and the
2828 lib/silcutil/win32/silcwin32schedule.c.
2830 * Added new function silc_task_queue_wakeup to wakeup the
2831 scheduler by the specified task queue. Affected file
2832 lib/silcutil/silctask.[ch].
2834 * The silc_socket_host_lookup_start now wakes up the scheduler
2835 after adding the timeout task. Affected file is
2836 lib/silcutil/silcsockconn.c.
2838 * The silc_socket_host_lookup is synchronous now if the threads
2839 support is not compiled in. However, the callback is still
2840 called asyncronously through the scheduler, anyway. Affected
2841 file lib/silcutil/silcsockconn.c.
2843 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Added new function silc_socket_host_lookup to perform
2846 asynchronous IP and FQDN lookups for the socket connection.
2847 Affected files lib/silcutil/silcsockconn.[ch].
2849 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2852 that may or may not compile the mutex support in.
2854 Changed the silc_mutex_alloc interface. It allocates the
2855 mutex now to the sent pointer and returns TRUE or FALSE.
2857 Affected file lib/silcutil/silcmutex.h.
2859 * Wrote the SILC Task Queue interface to support multi-threads.
2860 Affected file lib/silcutil/silctask.[ch].
2862 * Wrote the SILC Scheduler to support multi-threads. Affected
2863 file lib/silcutil/silcschedule.c.
2865 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2868 in lib/silcutil/win32/.
2870 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Defined SILC Mutex API and SILC Thread API and implemented
2873 them for Unix. Affected files are
2874 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2875 lib/silcutil/unix/silcunixmutex.c and
2876 lib/silcutil/unix/silcunixthread.c.
2878 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Fixed the silc_server_remove_clients_by_server's channel
2881 key re-generation. The hash table handling was incorrect
2882 and would not work with many channels. Affected file is
2885 * Fixed some memory leaks around the server code.
2887 * Rewrote the silc_server_get_users_on_channel to support IPv6
2888 based Client ID's. Affected file silcd/server.c.
2890 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2891 specification. However, a separate document must be written
2892 to define the detailed signing procedure and the payload
2893 associated with the flag. Defined the flag to the
2894 lib/silccore/silcchannel.h as well.
2896 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Changed the dynamic tables to static size tables in the
2899 lib/silccrypt/silchmac.c.
2901 * Removed GCC dependencies from the code. A patch by cras.
2903 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Do not show the error "Error receiving packet bla bla"
2906 in server if it really was not an error (-2 means that reading
2907 is pending). Affected file silcd/server.c.
2909 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Fixed a possible crash in silc_server_remove_clients_by_server
2912 in silcd/server.c. Fixed there also some memory leaks.
2914 * Fixed the silc_idlist_replace_client_id. It could replace
2915 wrong key in the hash table. Affected file silcd/idlist.c.
2917 * Do not check whether there are global users on the channel
2918 if the channel->global_users is FALSE. Affected functions
2919 silc_server_remove_from_one_channel and
2920 silc_server_remove_from_channels in silcd/server.c. Also,
2921 do not check if the removed client is local as we can be
2922 sure that global client was not removed from the channel
2923 and checking for global users is not needed.
2925 * The silc_server_remove_clients_by_server now re-generates
2926 the channel keys correctly for those channels that had
2927 clients removed from them. Affected file silcd/server.c.
2929 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Found the reason of random crashes in the server. We weren't
2932 ignoring the SIGPIPE signal (which can be sent in write())
2933 and it crashed the server. Affected file silcd/silcd.c.
2935 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Assure that sock->user_data is not NULL in the function
2938 silc_server_packet_send in silcd/packet_send.c.
2940 * Disconnect the remote connection if it could not be added
2941 to any ID lists in the server. The affected file is
2944 * Check in silc_server_packet_send[_real/dest] that the
2945 socket is not disconnecting and ignore the data if it is.
2946 Affected file silcd/packet_send.c.
2948 * Define inline to __inline on native WIN32 compilation.
2949 Affected file includes/silcwin32.h.
2951 * Added some explicit type casts for inline code since MSVC
2952 require them. Affected files lib/silcutil/silcbuffer.h,
2953 lib/trq/silcdlist.h and lib/trq/silclist.h.
2955 * Print warning in log files from now on if the packet
2956 decryption fails. Affected file silcd/server.c.
2958 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Changed the `say' client operation's interface to accept
2961 new `type' argument to indicate the type of the message sent
2962 by the library. The application may filter the library's
2963 messages according the type. The affected file is the
2964 lib/silcclient/silcapi.h.
2966 * Added two new functions to lib/silcclient/silcapi.h:
2967 silc_client_del_client and silc_client_del_client_by_id.
2968 Affected file lib/silcclient/idlist.c.
2970 * Moved the clientincludes.h from includes/ to silc/ and
2971 serverincludes.h from includes/ to silcd/.
2973 * The modes for the CMODE and CUMODE are now passed as
2974 uint32 for application with COMMAND_REPLY. The affected
2975 file is lib/silcclient/command_reply.c.
2977 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * /WHOIS without arguments shows client's own information.
2980 Affected file lib/silcclient/command.c.
2982 * Changed PING to not accept any arguments. The specs
2983 says that client can ping only the connected server so
2984 requiring an argument is not needed. Affected file is
2985 lib/silcclient/command.c.
2987 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Fixed a fatal bug in private message sending and reception
2990 encryption and decryption when using private message keys.
2991 The implementation was incorrect and did not follow the
2992 specification. It causd that some of the message were
2993 lost since it did not use the sending and receiving keys
2994 as the protocol suggests. This has been fixed and will cause
2995 incompatibilities with older clients when sending private
2996 message encrypted with private message keys. Affected files
2997 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2998 and various other in Irssi SILC Client.
3000 Added `responder' boolean argument to the functions
3001 silc_client_add_private_message_key[_ske] to indicate when
3002 the key is added as responder or initiator of the key
3005 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Removed the silc_ske_check_version function and created
3008 a SilcSKECheckVersion callback. Added also a function
3009 silc_ske_set_callbacks that is now used to set all SKE
3010 callbacks. The callback functions are not given to
3011 the SKE functions anymore, but this function is used to
3014 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3016 * Added `silc_version' argument to the silc_client_alloc
3017 to define the version of the application for the library.
3018 The library will use the version string to compare it
3019 against the remote host's (usually a server) version
3020 string. Affected file lib/silcclient/silcapi.h
3022 * Added the KE protocol context to Key Agreement context
3023 in client library so that we can abort the SKE if it
3024 is in process when we get timeout. Affected file is
3025 lib/silcclient/client_keyagr.c.
3027 * Do not resolve the client ID forever if it returns in the
3028 first time that such client does not exist. This was done
3029 for example with private message. Affected file is
3030 lib/silcclient/client_prvmsg.c.
3032 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Do not add regex.h for WIN32. The affected file
3035 includes/silcincludes.h.
3037 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3038 not work yet 100%. It generates the DLL's automatically
3039 when compiling with --with-win32 under cygwin.
3041 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * lib/contrib/regex.c is not compiled on WIN32.
3045 * Added silc_net_get_socket_opt function to the
3046 lib/silcutil/silcnet.h.
3048 * Added includes/silcwin32.h for WIN32 specific includes
3051 * Do not use ptime structure or any of the posix process
3052 functions on WIN32 in lib/silccrypt/silrng.c.
3054 * Added silc_gettimeofday to provide generic function
3055 for struct timeval on all platforms. Added the function
3056 to lib/silcutil/silcutil.h.
3058 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3061 library as they clearly belong there. As a plus side we
3062 can make the actual socket connection routines platform
3065 Added also new generic function silc_socket_read and
3066 silc_socket_write (that used to be silc_packet_[read/write].
3067 The implementation of these are platform specific.
3069 * Added WIN32 specific routines of silc_socket_[read/write]
3070 to lib/silcutil/win32/silcwin32sockconn.c.
3072 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Added preliminary support for native WIN32 compilation under
3075 cygwin (using the -mno-cygwin option for GCC) to the
3076 ./configure.in.pre. The --with-win32 now prepares the
3077 compilation for native WIN32.
3079 * Rewrote the SILC Scheduler interface in the file
3080 lib/silcutil/silcschedule.h. The scheduler is now context
3081 based and does not have anymore any global static scheduler.
3082 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3083 and created lib/silcutil/win32 directory for WIN32 based
3086 * Added Unix specific network routines to the
3087 lib/silcutil/unix/silcunixnet.c and the old
3088 lib/silcutil/silcnet.c includes now only generic routines.
3090 Added WIN32 specific network routines to the
3091 lib/silcutil/win32/silcwin32net.c.
3093 * Added Unix specific utility functions from the
3094 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3096 * Added WIN32 SILC Scheduler to the file
3097 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3100 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Do not handle JOIN notify in the server if the target client
3103 is not registered (idata->registered == FALSE). The affected
3104 file is silcd/packet_receive.c.
3106 * Update the nickrec->founder in event_cumode in the Irssi SILC
3107 client. Affected file irssi/src/silc/core/silc-channels.c.
3109 * Fixed the CUMODE_CHANGE notify handling in the server when
3110 server and router are announcing their clients on channels.
3111 Now the mode changes are saved and notified correctly. The
3112 affected file is /silcd/packet_receive.c.
3114 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3115 They really did not replace the cache entry in the ID Cache.
3116 Now they do that. Affected file silcd/idlist.c.
3118 * Fixed the KICK notify handling in the Irssi SILC client to
3119 update the channel records so that the kicked client does not
3120 appear to be on the channel. The affected file is
3121 irssi/src/silc/core/silc-channels.c.
3123 * Always update the conn->current_channel when executing command
3124 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3126 * Fixed the KILL notify handling in Irssi SILC client to remove
3127 the killed client on all channels.
3129 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Fixed the silc_parse_command_line to remove extra spaces
3132 from the start and end of the arguments. Affected file is
3133 lib/silcutil/silcutil.c.
3135 * Cancel and free any active protocol in the function
3136 silc_server_close_connection. Affected file silcd/server.c.
3138 * Cancel and free any active protocol in the function
3139 silc_client_close_connction. Affected file is
3140 lib/silcclient/client.c.
3142 * Do not execute the KILL command for clients that are in
3143 history (ie. they are not in the network). Affected file is
3146 * Fixed KILL notify handling, client does not crash anymore.
3147 Affected file irssi/src/silc/core/silc-channels.c.
3149 * Reduced the default packet buffer size from 2048 to 1024 in
3150 lib/silccore/silcpacket.c.
3152 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3153 counter to the SKE context that is incresed when the SKE library
3154 performs async operation outside the library. If the outside
3155 process frees the SKE context and FREED status will be set
3156 and the library will detect after the sync operation that the
3157 libary is freed. The affected files are
3158 lib/silcske/silcske[_status].[ch].
3160 * Resolve the client entry information in the function
3161 silc_client_channel_message to assure that NULL pointer is not
3162 passed as client entry to the application. */
3164 * Fixed the task timeout calculation to assure that there is
3165 never negative timeouts. The affected file is
3166 lib/silcutil/silcschedule.c.
3168 * Fixed the channel user mode notification sending in server.
3169 It was sent point-to-point to the router (or to server by router)
3170 but it needs to be destined to a channel. The routines now
3171 supports sending the channel user mode notifys to the channels
3172 when announcing clients and channels. Affected files are
3173 silcd/server.c and silcd/packet_receive.c.
3175 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3176 It did not actually replace the old channel entry in the cache.
3177 Affected file lib/silcclient/client_notify.c.
3179 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Fixed a possible crash in silc_packet_send_prepare. It now
3182 assures always that there is enough space in the buffer and
3183 at the tail area of the buffer (for MAC).
3185 Fixed the inbound buffer reallocation in silc_packet_read.
3186 It was old code and did not handle the reallocation correctly.
3189 The affected file is lib/silccore/silcpacket.c.
3191 * Fixed buffer overflow in silc_parse_nickname in the file
3192 lib/silcutil/silcutil.c.
3194 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * make install generates new server keys only if there is not
3199 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3202 Added check that if the NOREPLY is set then we will not send
3203 the away message. This avoids infinite loop of away messages
3204 if both clients are away. The affected file is
3205 lib/silcclient/client_prvmsg.c.
3207 * Fixed client crash if /NICK was given without arguments.
3208 Affected file lib/silcclient/command.c.
3210 * Server does not send the invite list in INVITE command back
3211 to the client if the list was not altered. Added this notion
3212 to the protocol spec as well. Affected file silcd/command.c.
3214 Fixed possible crash in INVITE command by checking the
3215 value of silc_server_get_client_route command.
3217 * Fixed the INVITE notify type handling. The arguments are now
3218 taken in correct order and client does not crash. The affected
3219 file is irssi/src/silc/core/silc-channels.c.
3221 Removed the "Inviting xxx to channel" message from the
3222 client library away and let the application handle it.
3223 Affected file lib/silcclient/command.c. Added that message
3224 to Irssi SILC client's message formats.
3226 * Fixed CMODE command crash in client. It now checks the
3227 amount of arguments correctly and does not crash. The affected
3228 file is lib/silcclient/command.c.
3230 * Do not create new channel automatically in silc_channels_join
3231 but check whether the channel by that name already exists.
3232 Affected file irssi/silc/core/silc-channels.c.
3234 * Do not send the SERVER_SIGNOFF to router if the disconnected
3235 entity was the router. Affected file silcd/server.c.
3237 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3238 SILC client as it was missing from there.
3240 Added the handling of the KICK notify to the Irssi SILC client
3241 as it was missing. Added "you have been kicked" message to
3242 Irssi SILC client's message modules formats.
3244 Added the handing of the KILL notify to the Irssi SILC client
3245 as it was missing. Added the kill message module formats
3248 The affected file is irssi/src/silc/core/silc-channels.c.
3250 * The router did not save the channel mode the server announced.
3251 Affected file silcd/packet_receive.c.
3253 * Fixed a possible crash in INFO command in server. If the
3254 server did not provide the server info it crashed. Affected
3255 file silcd/command.c.
3257 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Fixed the GETKEY command in the server to check also the
3260 global list. Otherwise the GETKEY would not work correctly
3261 in normal SILC server. Affected file silcd/command.c.
3263 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Fixed GETKEY crash, it crashed if the command did not succseed.
3267 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3270 is now real and not just an macro interface to GMP.
3272 Removed the entire GMP from the source tree and imported new
3273 NSS MPI library instead. Reason for removing GMP is that it is
3274 extremely large and compiles extremely slow. The NSS MPI
3275 is only a few files and compiles in less than 10 seconds.
3276 The speed is also about the same as GMP. The MPI is imported
3277 to lib/silcmath/mpi.
3279 If the system has GMP installed we will still use the GMP.
3280 If it is not then the NSS MPI will be compiled.
3282 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Merged a long nickname (127 characters long) crash bugfix from
3285 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3287 * Merged a freed memory reference bugfix from Irssi CVS tree.
3288 Affected file irssi/src/core/commands.c.
3290 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added the server's public key sving and verification to the
3293 server when performing the SKE. This was missing and the
3294 remote server's (or router's) public key was accepted without
3295 checking whether we have it previously or trust it at all.
3296 Affected file silcd/protocol.c.
3298 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Check in the silc_server_timeout_remote if protocol is active
3301 and make sure that the protocol's final callback is called so
3302 that all memory if freed. Affected file silcd/server.c.
3304 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * silc_server_whois_send_reply crashed the server if the nickname
3307 was 127 characters long. Affected file silcd/command.c.
3309 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Added sanity check to the silc_server_new_client. If the hostname
3312 is provided inside username then check that the provided hostname
3313 really is the same as the resolved one. If the hostname was not
3314 resolved then check it from the public key. Affected file is
3315 silcd/packet_receive.c.
3317 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3318 if the server disconnected us and the connection is not valid
3319 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3321 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3322 the library to the lib/silcutil/silcutil.[ch].
3324 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Close log file after open. Affected file
3327 lib/silcutil/silclog.c.
3329 * Check whether sock == NULL in silc_client_send_packet and return
3330 if it is. Affected file lib/silcclient/silcclient.c.
3332 * Check rec->entry == NULL in the Irssi SILC Client before
3333 sending the channel message. Affecte file is
3334 irssi/src/silc/core/silc-servers.c.
3336 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Merged a splitted window bugfix from Irssi CVS tree. The
3339 affected file is irssi/src/fe-text/textbuffer-view.c.
3341 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3342 It did not print nickname.
3344 * Improved the distributions system a bit.
3346 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3349 irssi/src/fe-text/gui-window.c.
3351 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3352 to in-active server. The affected file is
3353 irssi/src/silc/core/client_ops.c.
3355 * Resolve the client in USERS command reply if the entry does
3356 not have username resolved. The affected file is
3357 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3358 command to WHOIS command to really resolve stuff. The USERS
3359 is not used any more in any critical section so WHOIS can
3360 be used even though it might be slower than IDENTIFY.
3362 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3365 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Changed the protocol API a bit more consistent in the
3368 lib/silccore/silcprotocol.[ch].
3370 * Changed the following headers to ROBODoc format:
3372 lib/silccore/silcpayload.h
3373 lib/silccore/silcprotocol.h
3374 lib/silccore/silcsockconn.h
3376 All core library headers are now formatted.
3378 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Fixed a bug in Irssi SILC client; do not show that you are
3381 server/router operator if you really are not. Affected file is
3382 irssi/src/silc/core/client_ops.c.
3384 * Renamed silc_command_free_payload to silc_command_payload_free.
3385 Affected file lib/silccore/silccommand.h
3387 * Added silcmath.h to include the prototoypes of various routines
3388 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3391 * Changed the following headers to ROBODoc format:
3393 lib/silccore/silcchannel.h
3394 lib/silccore/silccommand.h
3395 lib/silccore/silcid.h
3396 lib/silccore/silcidcache.h
3397 lib/silccore/silcmode.h
3398 lib/silccore/silcnotify.h
3399 lib/silccore/silcpacket.h
3400 lib/silcmath/silcmath.h
3402 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Added checking to the server code not to start the server if
3405 ciphers and stuff are not configured properly. Affected files
3406 silcd/serverconfig.[h] and silcd/server.c.
3408 * Changed the layout of the header files of the public interfaces
3409 in the SILC libraries. The new layout supports ROBODoc
3410 documentation tool (and some others) so that it is easy to create
3411 a library reference manual. All the other headers and source
3412 code must still follow the CodingStyle document. Also source
3413 code must not include these ROBODoc stuffs, only the headers.
3414 Furthermore, all public interface headers must now be named
3415 by using `silc' prefix, example: silcapi.h, silccipher.h.
3416 Some files were renamed due to this. All the other headers
3417 must not be used as public interfaces. I will update the
3418 CodingStyle document later. Changed following headers, so far:
3420 lib/silcclient/silcapi.h
3421 lib/silccore/silcauth.h
3422 lib/silccore/silcprivate.h
3423 lib/silccrypt/silcdh.h
3425 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Removed silc_client_packet_send_flush from the client library
3430 as it is not needed. Affected file lib/silcclient/client.[ch].
3432 * Added printing of message of unresolved authentication method
3433 to the Irssi SILC client. Added it to the module formats.
3434 Removed the same message from the client library.
3436 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Added new distribution feature, DISTLABEL. Every distribution
3439 can define own preprocessor label that can be used in the
3440 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3441 file distributions, acconfig.h.pre and prepare.
3443 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Added Makefile.defines_int to include the actual definitions
3446 for Makefile.defines.in. Tested the new distribution system,
3447 created distributions and tested installation.
3449 * Added AWAY message printing to the Irssi SILC client. Added
3450 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3452 * Added SCONNECT command to call the SILC's CONNECT command.
3453 Cannot use CONNECT directly since Irssi uses that internally.
3454 Affected file irssi/src/silc/core/silc-servers.c.
3456 Added ACTION local command. It is same as ME command but takes
3457 the channel as mandatory argument.
3459 Rewrote some of the Irssi's help files to suite for SILC
3462 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Added Makefile.defines[.in] that should for now on be included
3465 in all Makefile.am file in the source tree. That file includes
3466 all common compilation definitions for SILC source tree.
3468 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Minor changes to the ./prepare script to change the package
3471 name according the distribution name to the configure.in.
3473 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Created new distribution system. Added file `distributions'
3476 that defines all the distributions that can be created out of
3477 the SILC source tree. The ./prepare script now reads that
3478 file to determine how to prepare the distributions. The
3479 first argument to the ./prepare is the name of the distribution
3480 and second is the version of the distribution. If given
3481 without arguments it creates the default (toolkit) distribution
3482 with the default version (defined in ./prepare).
3484 All Makefile.am files that are subject to the distributions
3485 are now named as Makefile.am.pre. These are ./Makefile.am
3486 and lib/Makefile.am. Others may be changed later.
3488 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Added invite list, ban list, some key management and connection
3491 error message printing to module formats in the Irssi SILC client.
3493 * Added new silc_client_set_away_message to set the away message
3494 that is back to the person who sent private message. The
3495 affected file lib/silcclient/silcapi.h and the
3496 lib/silcclient/client_prvmsg.c.
3498 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Fixed the private message sending in the Irssi SILC client,
3501 added local command KEY to the Irssi SILC client.
3503 Added key management and key agreement message formats to the
3504 irssi/src/fe-common/silc/module-formats.[ch].
3506 Added USERS (alias WHO) printing, server/router operator
3507 indication and LIST command printing to the module formats.
3509 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Fixed channel joining notify handling, cumode notify handling
3512 from Irssi SILC client.
3514 * Added SILC specific module-formats to the Irssi SILC client so
3515 that SILC specific message hilighting, colors etc is possible.
3516 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3518 Added channel mode, channel user mode, actions, notices,
3519 whois and whowas printing to the the module-formats.c.
3521 * Fixed a bug in channel deletion in the server. The channel
3522 is not left to the cache even if the channel founder auth mode
3523 is set when there are no users anymore on the channel. Affected
3524 file silcd/server.c.
3526 * The silc_net_localhost now resolves the entire hostname including
3527 the domain name. Affected file lib/silcutil/silcnet.c.
3529 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Changed the ask_passphrase client operation to be ascynchronous.
3532 It has now a completion callback and a context that the
3533 application must call after it has got the passphrase from
3534 the user. Affected files lib/silcclient/silcapi.h,
3535 lib/silcclient/protocol.c, lib/silcclient/command.c and
3538 Added SilcAskPassphrase callback that the application calls
3539 to deliver the passphrase to the library.
3541 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3542 The public key verification and especially a certificate
3543 verification is asynchronous procedure.
3545 Added new SILC_SKE_STATUS_PENDING status to indicate the
3546 request is pending and a callback will be called to finalize
3549 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3550 indicate that remote end did not send its public key (or
3551 certificate), even though we require it. Added check for this
3552 condition in the SKE. This was a security bug, now fixed.
3554 Defined new SilcSKEVerifyCbCompletion callback that is called
3555 when the verification process is completed.
3557 The affected files lib/silcske/silcske_status.h and
3558 lib/silcske/silcske.[ch].
3560 * Changed the verify_public_key client operation to be async
3561 as well. Defined SilcVerifyPublicKey callback that is used to
3562 indicate the success of the public key verification process.
3564 Changed the server and client to use the new async client
3567 * Changed the Irssi SILC client's internal scheduler to be called
3568 twice as many times as it used to be. As a result the client
3569 should be a bit faster now. Affected file is
3570 irssi/src/silc/core/silc-core.c.
3572 * Added support to Irssi SILC client of asynchronous public key
3573 verification and passphrase inquiry. Affected file is
3574 irssi/src/silc/core/silc-core.c.
3576 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Do not say "You have left channel %s" in client library.
3579 Moved it to the application. Affected files are
3580 lib/silcclient/command.c and silc/client_ops.c.
3582 * Fixed silc_client_get_clients. Command context was not
3583 duplicated and was freed memory in the callback. Affected
3584 file lib/silcclient/idlist.c.
3586 * Do not say "you are now talking..." on JOIN command in the
3587 client library. The appliation must handle it.
3589 * Do not say ".. changed topic to" in command reply in the
3590 client libary. The application must handle it.
3592 * Fixed TOPIC command sending in the client library.
3594 * Fixed a memory leak in silc_client_command_free in the file
3595 lib/silcclient/command.c.
3597 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Imported a modified version of Irssi client to the source tree.
3600 The Irssi will be used to create a new client called
3601 Irssi SILC. Imported to irssi/.
3603 Added silc_core_init_finish function to the Irssi. Affected
3604 file irssi/configure.in.
3606 A lot changes in the Makefile.ams around the irssi tree.
3608 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Do not rehash if the new size is same as the old size of the
3611 hash table, in the silc_hash_table_rehash*. The affected file
3612 lib/silcutil/silchashtable.c.
3614 * Replaced hash_table_del_by_context calls from the server
3615 (when channel->user_list and client->channels) to the
3616 hash_table_del as it is sufficient and faster.
3618 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Added silc_hash_table_list, silc_hash_table_get and the
3621 SilcHashTableList structure to provide an alternative way to
3622 traverse the hash table. The affected files are
3623 lib/silcutil/silchashtable.[ch].
3625 * Changed the server's idlist routines to use the hash table
3626 routines to optimize the code.
3628 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Replaced the client entry's `channel' list and channel entry's
3631 `user_list' list to hash tables for optimized lookup. Changed
3632 the code to use the hash table interface around the code.
3633 Affected file lib/silcd/idlist.[ch].
3635 * Added `auto_rehash' boolean argument to the function
3636 silc_hash_table_alloc to indicate whether the hash table should
3637 auto-rehash when it thinks is appropriate time. It will
3638 increase the hash table size if the there is twice as much
3639 entries in the table than the size of the table, and will
3640 decrease the size if there are twice as less entries than
3641 the size of the table.
3643 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3647 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * silc_idcache_purge_by_context deletes the entry now by context
3650 as it is supposed to do. Affected file lib/silccore/idcache.c.
3652 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3653 client is not anymore valid (WHOWAS givens the info) and not
3654 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3656 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Removed the `data' and `data_len' arguments from the ID Cache
3659 interfaces and added `name' argument. ID Cache does not handle
3660 anymore the binary data only a names associated with given ID.
3662 * When hashing a Client ID with silc_hash_id the entire ID is
3663 not hashed anymore, instead only the hash of the Client ID is
3664 hashed. This way we can access the Client ID from the cache
3665 with Client ID but with the hash of the ID (which is a hash of
3666 the nickname) as well without any difference in performance.
3668 Added also silc_idcache_find_by_id_one_ext to do one on one
3669 searching when we have the actual ID. Added also function
3670 silc_hash_client_id_compare. The affected files are
3671 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3673 * When hashing the name associated with a ID it is always done
3674 in lowercase. This way we can access the cache without worrying
3675 about case-sensitivity, even though, for example nicknames are
3678 * Fixed a bug in server with channel message sending. It put
3679 wrong ID type as destination ID. The affected file
3680 silcd/packet_send.c.
3682 * silc_idcache_del_by_context now deletes from all hash tables
3683 by context. Affected file lib/silccore/idcache.c.
3685 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Changed the client library to use the new ID Cache interface.
3688 Changes around the source tree.
3690 * Added silc_hash_table_rehash_ext to rehash with specific
3691 hash function. Affected file lib/silcutil/silchashtable.[ch].
3693 * Added silc_hash_string_compare to compare two strings in the
3694 hash table. Affected file lib/silcutil/silcutil.[ch].
3696 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Added new function silc_idcache_del_by_context into the
3699 lib/silccore/idcache.[ch].
3701 * Changed the server's ID list routines to use the new ID Cache
3702 interface. Changes around the source tree.
3704 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Added silc_hash_table_del[_by_context]_ext functions in to the
3707 lib/silcutil/silchashtable.[ch].
3709 Removed silc_hash_table_find_all* routines and added new
3710 silc_hash_table_find_foreach to replace them.
3712 Added silc_hash_table_replace_ext function as extended
3713 replacing function. Separated the simple hash table interface
3714 from the extended hash table interface in the file
3715 lib/silcutil/silchashtable.h.
3717 * Fixed minor bugs and changed it to use some of the new
3718 hash table functions in lib/silccore/idcache.c
3720 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Added new function silc_hash_table_find_all to return all keys
3723 in the hash table by the specified key. As the hash table is
3724 collision resistant it also makes it possible to have several
3725 duplicate keys in the hash table. This function may be used to
3726 find all of the keys from the hash.
3728 Added user_context arguments to the SilcHashFunction,
3729 SilcHashCompare and SilcHashDestructor to deliver user specified
3732 Added new fuctions silc_hash_table_find[_all]_ext to do
3733 extended lookup with specified hash and compare functions and
3734 specified user contexts.
3736 Added new function silc_hash_table_add_ext to add the key
3737 with specified hash function and user context.
3739 Added new function silc_hash_table_foreach to traverse all
3740 entrys in the hash table. Added SilcHashForeach callback
3743 Added new function silc_hash_table_del_by_context to delete
3744 the entry only if the context associated with the key matches.
3746 Affected files are lib/silcutil/silchashtable.[ch].
3748 * Removed silc_hash_[server/client/channel]_id and added just
3749 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3750 silc_hash_id_compare to compare two ID's using as the hash table
3751 comparison function. Added also silc_hash_data to hash
3752 binary data and silc_hash_data_compare to compare it.
3754 * Removed silc_idlist_find_client_by_hash as it is not needed
3755 anymore. Affected file silcd/idlist.[ch].
3757 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3758 to use internally the SilcHashTable. The new ID Cache is a lot
3759 faster than the old one. Some of the ID Cache interface was also
3760 rewritten and obsolete and stupid functions were removed.
3762 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Added entry_count field to the SilcHashTable to keep the number
3765 of the entries in the table. Implemented the function
3766 silc_hash_table_rehash. Added new function
3767 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3769 Fixed a minor bug in silc_hash_table_free.
3771 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3772 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3773 into the lib/silcutil/silcutil.[ch].
3775 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Implemented a collision resistant hash table into the
3778 lib/silcutil/silchashtable[ch]. See the header and the source
3779 for the SilcHashTable API.
3781 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Merged dotconf version 1.0.2 into lib/dotconf.
3785 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Do not compile anything in lib/silcsim/* if the SIM support
3788 is not enabled. The tree should now compile without problems
3791 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Compiled the SILC under cygwin. Compiled and tested briefly
3794 without problems. More tests needed. The SIMs didn't compile
3797 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3799 * Fixed possible crash in silc_get_username in the
3800 lib/silcutil/silcutil.c.
3802 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Fixed a va_arg in silc/client_ops.c.
3806 * Oops, RC5 routines were named AES and caused some problems
3807 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3809 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Added new SilcIDIP structure into the lib/silccore/id.h and
3812 replaced the old `ip' fields from all SILC ID's to that type.
3813 This is a step towards IPv6 support.
3815 The silc_id_get_len takes now the ID as an extra argument.
3816 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3817 both IPv4 and IPv6 based ID's.
3819 The affected files are lib/silccore/id.[ch] and other files
3820 around the tree using these routines.
3822 * Removed the ID length arguments in server from various
3823 silc_server_send_notify_* routines -> they are not needed
3826 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Fixed memory leak in silc_encode_pem_file in the file
3829 lib/silcutil/silcutil.c.
3831 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Check minor version as well in the SKE. Affected files are
3834 silcd/protocol.c and lib/silcclient/protocol.c.
3836 * Added --identifier option to the server so that an identifier
3837 can be when creating the public key for the server. Affected
3838 file is silcd/silcd.c.
3840 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3841 lib/silccrypt/silcpkcs.c.
3843 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Register default ciphers and stuff when using -C option with
3846 the server. Affected file sildc/silcd.c.
3848 * Put back the servers public key filename format, it is better
3849 than the new one. For now, the client keys are saved with the
3850 new filename format. The affected file silc/client_ops.c.
3852 * Implemented the Cipher API for the rest of the ciphers that
3853 did not implement it or implemented it the wrong way.
3855 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Register default ciphers and stuff when using the -S option
3858 in the client. Affected file silc/silc.c. Same also when
3859 creating new key pair with -C option.
3861 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Fixed the silc_verify_public_key client operation function to
3864 save the public keys differently. The fingerprint is now
3865 used as filename and not the hostname. This way also the
3866 client keys are saved uniquely and not with hostnames. The
3867 affected file is silc/client_ops.c.
3869 * Trimmed the silc_hash_fingerprint function to remove extra
3870 whitespaces from the end of the fingerprint. The affected
3871 file is lib/silccrypt/silchash.c.
3875 * Added silc_cipher_register_default function to register all
3876 default ciphers. It can be used when configuration files
3877 does not exist and the application does not want any specific
3878 ciphers in any specific order.
3880 The SilcDList is now used as silc_cipher_list dynamically
3881 allocated cipher list. Removed the static list all together
3882 and now all ciphers must be allocated to the dynamic list.
3883 The silc_cipher_alloc routine was changed to check only the
3886 All silc_cipher_* routines that used to return int returns
3889 The affected files lib/silccrypt/silccrypt.[ch].
3891 * The same thing was done to silc_hash_* as for silc_cipher_*
3892 routines. Affected files lib/silccrypt/silchash.[ch].
3894 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3895 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3896 Added also silc_pkcs_[un]register[_default] functions.
3897 Removed the data_context from the PKCS API.
3899 * Added silc_hmac_register_default function to register default
3900 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3901 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3902 to unregister all hmacs at once.
3904 * Register the default ciphers, hash functions, PKCSs and HMACs
3905 if client's configuration file does not exist. The affected
3908 * The client did not load the hash functions from the SIM
3909 modules at all. Added support for this. Affected file is
3910 silc/clientconfig.c.
3912 * When decoding public key with silc_pkcs_public_key_decode, check
3913 the supported algorithm only if PKCS are registered. Affected
3914 file lib/silccrypt/silcpkcs.c. The same was done with the
3915 silc_pkcs_private_key_decode.
3917 * Fixed the SILC List routines to keep the list always in order.
3918 It used to change the list's order when traversing the list but
3919 not it preserves the order. Affected file lib/trq/silclist.h.
3921 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Added the client library to use the SilcSocketConnection's
3924 reference counter (by silc_socket_dup) to prevent the bug that
3925 the socket object may be freed underneath async operation.
3927 * The name resolv library checking fixes in the configure.in.pre.
3930 * Created new version of the protocol drafts for future
3931 development. The -03 drafts are the ones that will be changed
3932 in the trunk now and the -02 will remain as they are.
3934 * Send list of CUMODE notifys to the router when announcing
3935 the channel users to the router. Affected file silcd/server.c.
3936 If the router receiving channel founder CUMODE for a channel
3937 that already has channel founder it will send CUMODE notify
3938 to the sender to remove the channel founder rights from the
3939 announced client. Affected file silcd/packet_receive.c.
3941 * The CUMODE notify may now use Server ID as well as the entity
3942 who changes the mode. Updated protocool specs.
3944 * Updated INSTALL and README files.
3946 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * New web pages in the http://silc.pspt.fi. The pages was
3953 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Implemented the [DenyConnectin] config section in the server.
3956 Added silc_server_config_denied_conn to check whether incoming
3957 connection is denied. Affected file silcd/serverconfig.[ch].
3959 * Do not check the ports when checking the incoming configuration
3960 data if the port is 0, meaning any. Affected file is
3961 silcd/serverconfig.c.
3963 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Fixed buffer overflow in silc_string_compare in the file
3966 lib/silcutil/silcutil.c.
3968 * Fixed double free in silc_server_command_leave in the file
3971 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Fixed the version checking in the server. Affected file is
3976 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Fixed the configuration data fetching when accepting new
3979 connections in the server. Affected file silcd/server.c.
3981 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Added `sender_entry' argument to the function
3984 silc_server_packet_relay_to_channel so that we can check
3985 whether some destination actually belongs to the same route
3986 the sender belongs (ie, we must not resend the packet to the
3987 sender). Affected file silcd/packet_send.[ch].
3989 * Added `servername' field to the SilcClientEntry in the server
3990 to hold the name of the server where client is from. Affected
3991 file is silcd/idlist.h.
3993 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Moved the channel message encrypting in the router betwen
3996 router connections from silc_server_channel_message to the
3997 silc_server_packet_relay_to_channel since we want to check
3998 whether we have anybody channel before encrypting anything.
3999 Affected files silcd/packet_[receive/send].c.
4001 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Fixed the [AdminConnection] server config section to support
4004 multiple entries. Affected file silcd/serverconfig.c.
4006 * Added support into the server to check the validity of the
4007 incoming connection before executing any KE or authentication
4010 * The connection configuration is now saved to the KE and
4011 connection auth protocol contexts and not fetched anymore in
4012 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4014 * The local hosts listenning address and port is also resolved
4015 now when starting the server. We want to have the socket object
4016 to include the real address and port for the listener. Added
4017 new function silc_net_check_local_by_sock into the files
4018 lib/silcutil/silcnet.[ch].
4020 * Fixed a broadcast bug in server -> do not broadcast if we
4023 * Fixed a routing bug. Do not route broadcast packets ever.
4024 Broadcast packets must be processed always and not routed since
4025 they may be destined to some other host than yourself and thus
4026 would get routed without no good reason. Affected file is
4029 * Added function silc_server_config_is_primary_route to check
4030 whether primary router connection has been configured (a router
4031 configuration that we are initiating). If there is not, we
4032 will assume that there is only two routers in the SILC network
4033 and we will use the incoming router connection as our primary
4034 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4036 * Changed the order of the broadcasting. Broadcast _after_ the
4037 packet has been processed not before. Affected file is
4040 * Fixed a [ClientConnection] parsing bug. The port was never
4041 parsed correctly thus resulting to port 0. Affected file
4042 silcd/serverconfig.c.
4044 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4045 argument and did not set the broadcast packet flag. Affected
4046 file silcd/packet_send.c. Fixed same bug in the function
4047 silc_server_send_notify as well.
4049 * If we receive NEW_ID packet for our own ID in the server, ignore
4052 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Removed the nickname from the Private Message Payload.
4057 Updated the code and the protocol specs.
4059 * Updated protocol specs for submitting to the IETF.
4061 * Tweaked the Random Number Generator a bit. Affected file
4062 lib/silccrypt/silcrng.c. Exported a new function
4063 silc_rng_[global]_add_noise which can be used to add more
4066 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Do not parse packets with different timeout when protocol
4069 is active -> may cause problem with rekey. Affected file
4072 * When server receives signoff notify it must not create
4073 new channel key if the client is on any channels since the
4074 sender of the signoff notify will create it.
4076 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Added printing of error messages during SKE protocol from the
4079 failure packet sent by server during SKE. Affected file
4082 * Removed the client's failure_callback handling with timeout
4083 and handle it immediately when received.
4085 * The SKE library returned wrong type in SUCCESS and FAILURE
4086 packets. They must be 32 bit MSB not 16 bit MSB.
4088 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Ok, rewrote the logic of the re-key and now it seems to work.
4091 I tested it on high traffic with frequent re-keys without
4092 problems. Added hmac_receive (and renamed hmac to hmac_send)
4093 in SilcClientConnection in lib/silcclient/client.h and
4094 in SilcIDListData in silcd/idlist.h. Also, removed the
4095 SilcPacketParserContext's cipher and hmac fields as they are
4096 not needed anymore and actually caused some problems when
4097 the ciphers and hmac's changed underneath the packet parser.
4099 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * If re-key protocol is active then process the incoming packets
4102 synchronously since we must assure that icoming packets encrypted
4103 with the old key is processed before the new keys is set to
4104 use. This is true other packets than for REKEY packets.
4105 Affected file silcd/server.c. The same was done to client library
4106 as well, affected file lib/silcclient/client.c.
4108 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Fixed bug in client and server to accept the force send if
4111 the packet is send from silc_[server/client]_packet_process
4112 function. Otherwise the packets are never delivered, oops.
4114 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Disable force sending of packets when REKEY protocol is active.
4117 We must assure that no packet is sent directly when rekey is
4118 performed. All packets must be sent through packet queue.
4119 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4120 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4121 function is silc_[server/client]_packet_send_real to check
4124 * Replaced the SIM paths from example config files to
4125 /usr/local/modules. Also, make install creates now
4126 /usr/local/silc/logs directory to hold all the SILC server
4129 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Made the configure.in.pre work on Solaris. Patch by salo.
4133 * Made all ciphers compatible with non-x86 machines. Defined
4134 CBC mode macros into lib/silccrypt/ciphers_def.h.
4136 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Fixed the make install.
4140 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * When MAC computation fails the silc_packet_decrypt returned 0
4143 even though it was supposed to return -1. Fixed this. The
4144 affected file is lib/silccore/silcpacket.c.
4146 * Do not replace the config files in /etc/silc (in make install)
4147 if they already exist. Affected file ./Makefile.am.
4149 * Do not send re-key packets immediately but through packet queue.
4150 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4152 * Changed silc_net_check_host_by_sock to return FALSE if the
4153 IP/DNS could not be resolved. Though, it returns the IP address
4154 now even if it could not resolve it (but returns also FALSE).
4155 Affected file lib/silcutil/silcnet.[ch].
4157 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Added silc_pkcs_decode_identifier to decode the public key's
4160 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4161 Added also silc_pkcs_free_identifier. Added also new context
4162 SilcPublicKeyIdentifier.
4164 * Added -S option to the silc client. It is used to dump the
4165 contents of the specified public key file.
4167 * Changed the PKCS api to return the public key length when
4168 setting the public key.
4170 * Fixed a fatal bug in the public and private key file loading.
4171 Affected file lib/silccrypt/silcpkcs.c.
4173 * Execute the packet parsing for client with zero (0) timeout
4174 if the protocol is active. Affected file silcd/server.c.
4176 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Made the key generation options to the silcd program. Added
4179 -C option, equivalent to client's option.
4181 * Added new [ServerKeys] config section to the server. It
4182 configures the server's public and private key.
4184 * Defined generic Public Key Payload into the protocol
4185 specification to send specific type of public keys and
4188 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4189 public key or certificate.
4191 * Implemented the GETKEY command to the server and to the
4192 client library and on user interface.
4194 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Made preliminary `make install' work.
4198 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Added SilcServerRekey context into silcd/idlist.h.
4202 * Added the PFS support as defined in the specification to the
4203 SKE protocol. Affected files lib/silcske/*.c.
4205 * Added `ske_group' field to the SilcServerRekey context to hold
4206 the number of the SKE group that is used with PFS in re-key.
4207 Affected file silcd/idlist.h.
4209 * Added PFS re-key support to the server. Affected file is
4212 * Added silc_protocol_cancel to cancel execution of the next
4213 state of the protocol. Affected file is
4214 lib/silccore/silcprotocol.[ch].
4216 * Added the re-key support with and without PFS to the client
4217 library. Re-key is performed once in an hour, by default.
4219 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4220 Added silc_client_rekey_callback and silc_client_rekey_final.
4221 Affected files are lib/silcclient/protocol.[ch] and
4222 lib/silcclient/client.[ch].
4224 * Removed the `hmac_key' and `hmac_key_len' fields from the
4225 SilcClientConnection structure; not needed. Affected file is
4226 lib/silcclient/client.h.
4230 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Do not ask whether user wants to use the negotiated private key
4233 for private messages, just use it. Affected file is
4234 silc/local_command.c.
4236 * Added `send_enc_key' and `enc_key_len' fields to the
4237 SilcIDListData structure since they are needed in the re-key
4238 phase. Affected file is silcd/idlist.[ch].
4240 * Implemented the simple re-key protocol into the server.
4241 Affected files silcd/server.c and silcd/protocol.[ch]. The
4242 re-key will be performed once in an hour, by default.
4244 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4245 Added silc_server_rekey, silc_server_rekey_callback and
4246 silc_server_rekey_final.
4248 * Removed Tunneled flag from the protocol. Updated the code
4249 and the specifications.
4251 * Adde `pfs' field to the SilcIDListData to indicate whether
4252 the PFS is to be performed in the re-key. Affected file is
4255 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4258 int64 of at least the xintXX size. If void * is less that 4
4259 bytes uint32 * will be used. Defined bool as boolean.
4261 * Changed _ALL_ unsigned long and unsigned int to uint32,
4262 unsgined short to uint16 in the source tree.
4264 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4265 not handle clients that has entry->data.registered == FALSE.
4266 They are not in the network anymore. Affected file is
4269 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Implemented the sending of the SERVER_SIGNOFF notify in the
4272 server. Affected file is silcd/server.c.
4274 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4275 Added also silc_notify_payload_encode_args into the
4276 lib/silccore/silcnotify.[ch].
4278 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4279 Affected file silcd/packet_receive.c.
4281 * Implemented the SERVER_SIGNOFF notify handling in the client
4282 library. Affected file lib/silcclient/client_notify.c. Also,
4283 implemnted the printing of the SERVER_SIGNOFF info to the
4284 application. Affected file silc/client_ops.c.
4286 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4287 if the deleting was successful. Affected file silcd/idlist.[ch].
4289 * Added support for public key authentication in the connection
4290 authentication protocol in the client library. Affected file
4291 lib/silcclient/protocol.c.
4293 * Changed the server's silc_idlist_get_clients_by_* interface
4294 to support already allocated array so that new entries may be
4295 added to pre-allocated array. Affected file silcd/idlist.[ch].
4296 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4297 and command replies.
4299 * All command reply functions in the server now calls the
4300 pending command callback even if error occured. This way the
4301 error will be delivered to the client as well. Affected files
4302 silcd/command.c and silcd/command_reply.c.
4304 * Fixed INFO command to return local server's info if no server
4305 was provided. Affected file lib/silcclient/command.c.
4307 * Removed RESTART command for good. Updated the code and the
4310 * Rewrote parts of the task system. It is a bit simpler now.
4311 Removed unsued task priorities. The affected files are
4312 lib/silcutil/silctask.[ch].
4314 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Moved the USERS printing from the library to the application.
4317 Affected files lib/silcclient/command.c and silc/client_ops.c.
4319 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Added channel key re-key support. The re-key is perfomed
4324 only by the router and is done once in an hour. Added `rekey'
4325 field to the SilcChannelEntry in the server. Affected files
4326 silcd/server.c and silcd/idlist.h.
4328 * Added silc_task_unregister_by_context into the file
4329 lib/silcutil/silctask.[ch].
4331 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added SILC_UMODE_GONE mode to indicate when the client is not
4334 present in the SILC network. Added also support to the local
4335 command AWAY that will set this mode. Added support of showing
4336 "xxx is gone" in WHOIS command. The USERS command shows the
4337 gone status as well.
4339 * Fixed setting server and router operator privileges in the
4340 server's UMODE command. Affected file silcd/command.c.
4342 * Merged the SKE KE1 and KE2 payloads into one payload. The
4343 new KE payload is equivalent to the old KE2 payload.
4345 Cleaned up the SKE Start Payload parsing. It now uses the
4346 simple buffer unformatting to do the parsing. A lot faster
4349 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4350 to the SKE that is used to indicate whether both of the SKE
4351 parties should perform authentication. By default only the
4352 responder performs authentication. By setting this flag also
4353 the initiator must do authentication. By default it is unset
4354 since in normal SKE case, client to server connection, only
4355 the responder should do authentication. When doing SKE between
4356 two clients both should perform authentication. Updated the
4357 code and the protocol specs.
4359 * A little fix to IDENTIFY command in the server. Search the
4360 client first by hash not nickname. Affected file is
4363 * Fixed the silc_client_close_connection to support closing
4364 the client to client connections wihtout deleting too much
4365 data. Affected file lib/silcclient/client.c.
4367 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4368 are received if protocol used to be active but is not anymore
4369 the application would crash due to NULL pointer dereference.
4370 Affected files silcd/server.c and lib/silcclient/client.c.
4372 * Added `hash' field to the SilcClientConnection to include
4373 the hash function negotiated in the SKE protocol.
4375 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4376 to set the channel founder authentication data. A client can
4377 claim the founder rights later by providing the authentication
4378 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4379 This way the channel founder can regain the channel founder
4380 privileges even it is left the channel. This works only on
4381 local server and the client must be connected to the same
4382 server to be able to regain the founder rights. Updated the
4383 protocol specs accordingly.
4385 Added support to the CMODE command in the client to set the
4386 founder auth data. Read the README to see how to set it.
4388 Added support to the CUMODE command to claim the founder
4389 rights. Read the README to see how to do it.
4391 Added support for the founder authentication to the Channel
4392 Entry in the server. Affected file silcd/idlist.h.
4394 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4395 server's CMODE command. Affected file silcd/command.c.
4397 * Added the following new functions into lib/silccore/silcauth.[ch]:
4398 silc_auth_get_method and silc_auth_get_data.
4400 * The server now saves the remote hosts public key to the
4401 SilcIDListData pointer. Affected file silcd/protocol.c.
4403 * The normal server now does not remove the channel entry from
4404 the cache if the founder authentication data is set. It used
4405 to remove it if the founder was the last one on the channel on
4406 the server and left the channel. The auth data is saved and
4407 if the channel is re-joined later the old entry is used with
4408 the old auth data. Affected files silcd/command_reply.c and
4411 * Removed the `pkcs' field from the SilcIDListData structure
4412 in the server; it is not used. Affected file silcd/idlist.h.
4414 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Fixed packet processing on slow links. Partial packets were
4417 never re-processed because the incoming data buffer was cleared
4418 by the application. Application must not directly clear the
4419 sock->inbuf, the packet processing routines handle it. Fixed
4420 this in client library and in server.
4422 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Fixed the WHOIS and IDENTIFY send reply function to really
4425 check whether to send list or just one entry. Affected file
4428 * Cleaned up the LEAVE command's channel key distribution. The
4429 affected file silcd/command.c.
4431 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4432 can enforce the channel mode as well. In that case the ID
4433 includes the ID of the server. The code now enforces the
4434 mode change if the router have different mode than the server.
4436 * The notify client operation with CMODE_CHANGE notify can now
4437 return NULL client_entry pointer if the CMODE was not changed
4438 by client. Application must check for this.
4440 * Added <Server ID> argument to INFO command to support server
4441 info fetching by Server ID.
4443 * Added silc_server_announce_get_channel_users to get assembled
4444 packets of channel users of the specified channel. Affected
4445 file silcd/server.[ch].
4447 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4448 was freed underneath the ID Cache.
4450 * Re-announce clients when the server received CHANNEL_CHANGE
4451 notify from the router. Affected file silcd/packet_send.c.
4453 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4456 crashed since it did not handle the fact that there is no cipher
4457 called "3" and didn't check the error condition. Now fixed.
4459 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4460 flag. It can be used to send message requests.
4462 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Implemented the RESTART command in the client.
4466 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4467 notice type messages. Added notice printing to the user
4470 * The channel keys are not re-generated if the channel's mode
4471 is PRIVKEY, ie private key on the channel exists. Affected
4472 files silcd/server.c and silcd/command.c.
4474 * Fixed a little bug in channel message delivery when channel
4475 private keys are set in the server. Affected file is
4476 silcd/packet_send.c.
4478 * Changed the setting on channel->on_channel = TRUE from the
4479 silc_client_save_channel_key to the JOIN command reply. The
4480 key payload is not received if the private channel key is set.
4481 Affected file lib/silcclient/command_reply.c and the
4482 lib/silcclient/client_channel.c.
4484 * When the CMODE_CHANGE notify is sent and the channel private
4485 key mode is removed the channel key must be re-generated in
4486 other cells as well. Added this support for the router in the
4487 silcd/packet_receive.c.
4489 * Added new local command NOTICE to send notice message on
4490 channel. Affected file silc/local_command.[ch].
4492 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Added new local command ME to the client. It is used to send
4495 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4496 some action. Affected file silc/local_command.[ch].
4498 * Changed channel_message and private_message client operations
4499 to deliver the message flags to the application. Added also
4500 the `flags' arguments to the silc_client_send_channel_message
4501 and silc_client_send_private_message functions. Affected file
4504 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Redefined the Private Message Payload to support private message
4507 keys and to support the new private message flags. Updated
4508 the protocol specs. Flags makes it possible to have for example
4509 CTCP style messages.
4511 * Added new type SilcPrivateMessagePayload and defined an API
4512 for it in the lib/silcclient/silcprivate.[ch].
4514 * Tested private message private keys successfully. Tested the
4515 private message key set, unset and list commands with the new
4518 * Redefined the Channel Message Payload to include the channel
4519 message flags (equal with private message flags) to support
4520 for example CTCP style messages.
4522 * Defined some of the message (for channel and private message)
4523 flags. Updated the protocol specs and added the flags to the
4524 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4526 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Added SilcKeyAgreementStatus type to the key agreement routines
4529 to indicate the current status and error if one occured.
4530 The status types are defined in the lib/silcclient/silcapi.h.
4532 * Added new local command KEY that is used to set and unset private
4533 keys for channels, set and unset private keys for private messages
4534 with remote clients and to send key agreement requests and
4535 negotiate the key agreement protocol with remote client. The
4536 key agreement is supported only to negotiate private message keys,
4537 it currently cannot be used to negotiate private keys for channels,
4538 as it is not convenient for that purpose.
4540 * Fixed a minor pending callback setting bug in the function
4541 silc_client_get_client_by_id_resolve, now the function works.
4542 Affected file lib/silcclient/idlist.c.
4544 * Added function silc_net_get_local_port to get local bound
4545 port by socket. Added to lib/silcutil/silcnet.[ch].
4547 * Added `sockets' and `sockets_count' fields to the SilcClient
4548 object. They hold the sockets of the listenning sockets in
4549 the client. Listenning sockets may be for example the key
4550 agreement server. Affected file lib/silcclient/client.[ch].
4551 Added functions the silc_client_add_socket and the
4552 silc_client_del_socket. They are exported to the application
4555 * Added ~./silc/clientkeys to support other client's public keys.
4557 * Renamed verify_server_key client operation to verify_public_key
4558 and added one argument to indicate the type of the connection
4559 (server, client etc.).
4561 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Added silc_server_connection_auth_request to handle the
4564 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4565 silcd/packet_receive.[ch].
4567 * Added silc_server_send_connection_auth_request into the
4568 silcd/packet_send.c to send the connection auth request packet.
4570 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4573 * Fixed the public key authentication in responder side in the
4574 server. The `auth_data' pointer includes the SilcPublicKey
4575 not the path to the public key. Affected file silcd/protocol.c.
4577 * Implemented the public key authentication in the initiator side
4578 in the server. Affected file silcd/protocol.c.
4580 * Removed the [RedirectClient] config section from the server
4581 configuration. Is not needed and I don't want to implement it.
4583 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Cleaned up the CMODE command in the server. It now works
4586 correctly and supports all the modes defined in the protocol.
4587 Affected file is silcd/command.c.
4589 * Added `hmac_name' field to the SilcChannelEntry in the server
4590 to hold the default HMAC of the channel. It can be set when
4591 creating the channel (with JOIN command). Affected files
4594 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4595 type to indicate the change of the current cipher and hmac
4596 on the channel. Client can safely ignore the <cipher> argument
4597 (if it chooses to do so) since the CHANNEL_KEY packet will
4598 force the channel key change anyway. The <hmac> argument is
4599 important since the client is responsible of setting the new
4600 HMAC and the hmac key into use.
4602 * Fixed the CMODE command in the client library as well.
4604 * Tested CMODE command in router environment successfully.
4606 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Show the version of the remote client (or server) when connecting
4609 to the server. It is logged to the log file. Affected file
4610 is silcd/protocol.c.
4612 * Fixed the KILLED notify handling in the client library. The
4613 client must be removed from all channels when receiving the
4616 Also, do not remove the client entry when giving the KILL
4617 command but when the KILLED notify is received.
4619 * Removed silc_idlist_find_client_by_nickname from the server.
4620 Not needed anymore. Affected files silcd/idlist.[ch].
4622 * Implemented the CHANNEL_CHANGE notify type handling to the
4623 server. Affected file silcd/server.c.
4627 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Added silc_server_send_notify_invite to send the INVITE
4630 notify between routers.
4632 * Implemented the INVITE command correctly to the server.
4634 * Implemented the INVITE notify type handling in the server.
4636 * Implemented the INVITE command to the client library and on the
4639 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added function silc_server_get_client_resolve to find the
4642 client entry by ID from all ID lists and then resolve it
4643 (using WHOIS) if it cannot be found. Affected file is
4646 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Implemented the BAN command to the client library.
4650 * The JOIN command in the server now checks the invite list
4653 * Changed the silc_command_reply_payload_encode_va and the
4654 silc_command_payload_encode_va to support that if argument is
4655 NULL it ignores and checks the next argument. Affected file
4656 lib/silccore/silccommand.c.
4658 * Added silc_server_send_notify_ban to send the BAN notify
4659 type between routers.
4661 * Chaned the silc_notify_payload_encode to support that if
4662 argument is NULL it ignores and checks the next argument.
4663 Affected file lib/silccore/silcnotify.c.
4665 * Tested ban lists in router environment successfully.
4667 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Implemented BAN command to the server, in silcd/command.[ch].
4671 * Removed the BAN and INVITE_LIST modes from the CMODE command
4674 * Added function silc_string_match to regex match two strings.
4675 Affected files lib/silcutil/silcutil.[ch].
4677 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Redefined parts of the SilcChannelEntry in the server to support
4680 the new ban and invite lists.
4682 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Redefined the INVITE command. The same command can be used to
4685 invite individuals to the channel but also to manage the invite
4686 list of the channel (to add to and remove from the invite list).
4687 Updated the protocol specs.
4689 * Added new command SILC_COMMAND_BAN that can be used to manage
4690 the ban list of the channel. Updated the protocol specs.
4692 * Removed the channel modes: the SILC_CMODE_BAN and the
4693 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4694 in the CMODE command. The equivalent features are now available
4695 using INVITE and BAN commands. Updated the protocol specs.
4697 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4698 in the network about change in the current ban list. The notify
4699 type is not used by the client.
4701 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4702 support the invite lists.
4704 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Added new function silc_string_regexify that converts string
4707 including wildcard characters into regex string that can
4708 be used by the GNU regex library. Added into the file
4709 lib/silcutil/silcutil.[ch].
4711 Added silc_string_regex_combine to combine to regex strings
4712 into one so that they can be used as one regex string by
4713 the GNU regex library. Added into the file
4714 lib/silcutil/silcutil.[ch].
4716 Added silc_string_regex_match to match two strings. It returns
4717 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4719 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Imported GNU regex to the soruce tree into lib/contrib.
4722 Fixed some compiler warning from the regex.c.
4724 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Fixed MOTD command in the server to work in router environment.
4728 * Fixed the MOTD command in the client library to support
4729 the server argument in the command.
4731 * Added `nickname_len' argument to the silc_idlist_add_client
4732 in the server, as the `nickname' argument may be binary data
4735 * Added silc_idlist_get_channels to return all channels from
4738 * Implemented LIST command to the server. Affected file is
4741 * Implemented the LIST command to the client library and on the
4744 * Added [<user count>] argument to the LIST command reply.
4745 With private channels the user count is not shown.
4747 * Updated TODO and README.
4749 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * The client entry's data.registered must be TRUE even with
4752 global client entry on global client list. The data.registered
4753 is used to check whether the client is anymore in the network,
4754 for example with WHOWAS command so it must be valid.
4756 * Fixed the WHOWAS command in the server. It now actually works
4757 in router environment. Added function into silcd/command_reply.c
4758 silc_server_command_reply_whowas_save.
4760 * Added silc_idlist_purge function to the silcd/idlist.c
4761 to periodically purge the ID Cache.
4763 * Fixed INFO command in the server. It works now in router
4764 environment. Added <server name> argument to the INFO command
4765 reply. Updated the protocol specs.
4767 * Fixed minor bug in silc_idcache_purge to not purge if the
4768 expire value is zero.
4770 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4771 they were buggy because of the WHOWAS information.
4773 * Fixed local command MSG to handle the async resolving of
4774 the remote client properly. It used to fail the first MSG.
4775 Affected file silc/local_command.c.
4777 * Added `data_len' field to SilcIDCache context.
4779 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Update TODO. Todo in commands in the server.
4783 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4786 used by routers as broadcast packet to inform other routers
4787 about the changed user mode.
4789 Implemented the notify handling in the server. Affected file is
4790 silcd/packet_receive.c. Added the function
4791 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4793 * Added new generic Channel Payload and deprecated the New Channel
4794 Payload. The New Channel Payload is now the generic Channel
4797 * Added new argument `mode' to the silc_server_send_new_channel
4798 as it is required in the Channel Payload now.
4800 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4801 and created a new and real SilChannelPayload to represent the
4802 new generic Channel Payload. Implemented the encode/decode
4803 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4805 * Added silc_server_get_client_channel_list to return the list
4806 of channels the client has joined for WHOIS command reply.
4807 Affected file silcd/server.[ch].
4809 * Implemented the channel list sending in the WHOIS command reply
4810 in server and in the client.
4812 Implemented the channel list displaying on the user interface
4813 as well. Affected file silc/client_ops.c.
4815 * Added silc_channel_payload_parse_list to parse list of Channel
4816 Payloads. It returns SilcDList list of SilcChannelPayloads.
4817 Client for example can use this function to parse the list of
4818 channels it receives in the WHOIS command reply. The caller
4819 must free the list by calling silc_channel_payload_list_free.
4820 Affected files lib/silccore/silcchannel.[ch].
4822 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Added one new argument <user mode> to the WHOIS command reply
4825 to return the mode of the user in SILC. Updated the protocol
4828 Implemented it to the server and client.
4830 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Fixed the mode printing on the user interface on joining.
4833 Affected file silc/client_ops.c.
4835 * Implemented the UMODE command and user modes in general to the
4836 client library and to the user interface.
4838 * Implemented the UMODE command to the server.
4840 * The server now sends UNKNOWN_COMMAND error status if client sends
4841 unknown command. Affected file silcd/command.c.
4843 * All server commands now handle the command identifier the right
4844 way when sending the command reply to the client. The client can
4845 use to identify the command replies with the identifier.
4847 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Added silc_server_get_client_route to resolve the route to
4850 the client indicated by the client ID. Affected file is
4853 * Added silc_server_relay_packet as general function to relay
4854 packet to arbitrary destination. This deprecates functions
4855 like _send_private_message_key, _relay_notify etc. Affected
4856 file is silcd/packet_send.[ch].
4858 Removed silc_server_send_key_agreement,
4859 silc_server_send_private_message_key and
4860 silc_server_packet_relay_notify functions from the file
4861 silcd/packet_send.[ch].
4865 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4866 server. Affected file silcd/packet_receive.[ch].
4868 * Implemented the KILL command to the client. Implemented the
4869 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4870 Affected files lib/silcclient/command[_reply].c and
4871 lib/silcclient/client_notify.c. Implemented the KILL notify
4872 printing in the user inteface.
4874 * Fixed a lot silc_parse_nick memory leaks from the client
4875 library in the file lib/silcclient/command.c.
4877 * Changed the silc_server_send_notify_on_channels's `sender'
4878 argument from SilcSocketConnection to SilcClientEntry to
4879 check the sender as entry and not as connection object and not
4880 to send to the client provided as argument. The affected file
4881 is silcd/packet_send.[ch].
4883 * The notify packets that are destined directly to the client used
4884 to not to be processed by the server. Now changed that and the
4885 server processes all notify packets. After relaying the packet
4886 to the client the notify packet is processed in the server.
4888 * The silc_server_free_client_data now checks whether there is
4889 pending outgoing traffic for the client and purges the data to
4890 the network before removing the client entry.
4892 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4895 an client is killed from the SILC Network. Updated the protocol
4898 Added new function silc_server_send_notify_killed to the
4899 silcd/packet_send.[ch].
4901 * Added function silc_server_packet_relay_notify to relay notify
4902 packets that are destined directly to a client. In this case
4903 the server does not process the notify packets but merely relays
4904 it to the client. Affected file silcd/packet_send.[ch].
4906 Added also silc_server_packet_process_relay_notify to check
4907 whereto relay the notify. Affected file is
4908 silcd/packet_receive.[ch].
4910 * Implemented the KILL command to the server.
4914 * Added the backup schema desgined last fall to the protocol
4915 specs for everyone to see. The specification is in the
4916 *-spec-xx.txt draft and the packet type definitions for the
4917 backup routers is in *-pp-xx.txt draft. Thusly, added also
4918 new packet type SILC_PACKET_CELL_ROUTERS.
4920 * A big security problem in the implementation discovered. The
4921 signoff of an client did not cause new channel key generation
4922 which it of course should've done. The channel keys must be
4923 always re-generated when client leaves (or signoffs) the channel.
4924 The silc_server_remove_from_channels funtion now handles
4925 the channel key re-generation.
4927 * Added `sender' argument to the silc_server_send_notify_on_channels
4928 to not to send the client provided as argument. Affected file
4929 silcd/packet_send.[ch].
4931 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Implemented OPER and SILCOPER commands into the server and
4936 * Added silc_auth_verify and silc_auth_verify_data to verify
4937 the authentication directly from the authentication payload.
4938 It supports verifying both passphrase and public key based
4939 authentication. Affected file lib/silccore/silcauth.[ch].
4941 * Added `hash' field to the SilcIDListData structure. It is the
4942 hash negotiated in the SKE protocol. Affected file is
4945 * Slight redesigning of the SilcAuthPayload handling routines.
4946 Do not send SilcPKCS but SilcPublicKey as argument.
4948 * Implemented the public key authentication support to the
4949 serverconfig. The public key is loaded from the provided path
4950 and saved as authentication data to void * pointer. Thus,
4951 changed the unsigned char *auth_data to void *auth_data;
4953 * Fixed SHUTDOWN command to send the reply before the server
4954 is shutdown. :) Affected file silcd/command.c.
4956 * Fixed fatal bug in CONNECT command. The hostname was invalid
4957 memory and server crashed. Affected file silcd/command.c.
4959 * Fixed fatal bug in CLOSE command. The server_entry became
4960 invalid but was referenced later in the command. Affected file
4963 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Fixed fatal bug in failure packet handling. Server ignored
4966 the failure and thus crashed when it came.
4970 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4973 that the command may be executed only once in (about) 2 seconds.
4974 The old SILC_CF_LAG flag is same but allows command bursts up
4975 to five before limiting.
4977 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4978 server code. Various commands now includes the CF_LAG_STRICT
4979 flag to disallow any kind of miss-use of the command.
4981 * Fixed the silc_buffer_unformat to not to allocate any data
4982 if the length of the data is zero. It used to allocate the
4983 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4985 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Changed the format of AdminConnection configuration section
4988 in the server. Added username of the admin to the format.
4989 Affected files silcd/serverconfig.[ch].
4991 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4992 to return admin configuration data by host, username and/or
4995 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Implemented WHOWAS command to the server. Added the functions:
4999 silc_server_command_whowas_parse,
5000 silc_server_command_whowas_send_reply,
5001 silc_server_command_whowas_from_client and
5002 silc_server_command_whowas_from_server
5004 * Added <Client ID> argument to the WHOWAS command reply. Updated
5005 the protocol specs accordingly.
5007 * Implemented WHOWAS command and command_reply to the client
5010 Implemented the WHOWAS printing on the user interface.
5012 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Added new argument to the WHOWAS command reply, the real name.
5015 It is an optional argument. Updated the protocol specs.
5017 * Added SilcIDCacheDestructor callback that is registered when
5018 the SilcIDCache is allocated. The callback is called when
5019 an cache entry in the ID Cache expires, or is purged from the
5020 cache. Added into lib/silccore/idcache.[ch].
5022 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5023 to destruct the client entries when the cache entry expires.
5024 Other ID Cache's in server and in the client library ignores
5027 * If the ID Cache entry's `expire' field is zero then the entry
5028 never expires. Added boolean `expire' argument to the
5029 silc_idcache_add function in the lib/silccore/idcache.[ch].
5030 If it is TRUE the default expiry value is used.
5032 * Added silc_server_free_client_data_timeout that is registered
5033 when client disconnects. By default for 5 minutes we preserve
5034 the client entry for history - for WHOWAS command.
5036 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added support to the server to enforce that commands are not
5039 executed more than once in 2 seconds. If server receives
5040 commands from client more frequently, timeout is registered
5041 to process the commands. Affected file silcd/command.c.
5042 Added new function silc_server_command_process_timeout.
5044 * Changed NICK_NOTIFY handling in client library to check that
5045 if the client's nickname was changed, so there is no need to
5046 resolve anything from the server.
5048 * Removed error printing from the WHOIS and IDENTIFY commands.
5049 If error occurs then it is ignored silently in the client library.
5050 The application, however, may map the received error to
5051 human readable error string. The application currently maps
5052 the NO_SUCH_NICKNAME error to string.
5054 * Made the command status message public to the application. Moved
5055 them from lib/silcclient/command_reply.c to
5056 lib/silcclient/command_reply.h. The application can map the
5057 received command status to the string with the
5058 silc_client_command_status_message function.
5060 * Added check to the server to check that client's ID is same
5061 as the Source ID in the packet the client sent. They must
5064 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Added dist-bzip hook to the Makefile.am to make bzip2
5067 compressed distributions.
5069 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Server now enforces the maximum length for the nickname and
5072 the channel as protocol specification dictates. 128 bytes for
5073 nickname and 256 bytes for channel name.
5075 * Moved the WHOIS printing to the application. The client libary
5076 does not print out the WHOIS information anymore, the application
5077 must do it. Renamed silc_client_command_reply_whois_print to
5078 the silc_client_command_reply_whois_save.
5080 The client's idle time is also sent to the application now, and
5081 the idle is shown on screen.
5083 * Added silc_client_command_reply_identify_save to save the
5084 received IDENTIFY entries.
5086 * Do not check for channel private keys in message sending and
5087 reception if the channel does not have the PRIVKEY mode set.
5088 Affected file lib/silclient/client_channel.c.
5090 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5093 just surfaced after chaning the JOIN procedure.
5095 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Added silc_client_get_clients_by_list to get client entries
5098 from Client ID list, that is returned for example by JOIN
5099 and USERS command replies. The application should use this
5100 function for example when JOIN command reply is received to
5101 resolve the clients already on the channel (library does not
5102 do that anymore as USERS command reply is not used in the JOIN
5103 procedure anymore). Affected files lib/silcclient/silcapi.h and
5104 lib/silcclient/idlist.c.
5106 * JOIN command reply and USERS command reply returns now SilcBuffer
5107 pointers instead of unsigned char pointers when returning
5108 the client list and mode list.
5110 * Added <Client ID> argument to the JOIN command reply, mainly
5111 for the server to identify for which client the command was
5112 originally sent. Updated protocol specs accordingly.
5114 * Added SilcDlist private_key pointer to the SilcChannelEntry
5115 in the client to support the channel private keys. Affected
5116 file is lib/silcclient/idlist.h.
5118 * Added SilcChannelPrivateKey argument to the function
5119 silc_client_send_channel_message so that application can choose
5120 to use specific private ke if it wants to. If it is not provided,
5121 the normal channel key is used, unless private keys are set.
5122 In this case the first (key that was added first) is used
5123 as the encryption key.
5125 * Implemented the support for channel private key handling.
5126 Implemented the following functions:
5128 silc_client_add_channel_private_key,
5129 silc_client_del_channel_private_keys,
5130 silc_client_del_channel_private_key,
5131 silc_client_list_channel_private_keys and
5132 silc_client_free_channel_private_keys
5134 Affected file lib/silcclient/client_channel.c.
5136 * Added the support for the private keys in the channel message
5137 sending and encryption and in the message reception and
5138 decryption. Affected funtions are
5139 silc_client_send_channel_message and silc_client_channel_message.
5141 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Added SKE's key verify callback to the client library's
5144 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5146 * Removed the statement that server (or router) must send USERS
5147 command reply when joining to the channel so that the client
5148 knows who are on the channel. Instead, the client list and
5149 client's mode list is now sent in the JOIN command reply to the
5150 client who joined channel. This is better solution.
5152 * Added function silc_server_get_users_on_channel and function
5153 silc_server_save_users_on_channel to the silcd/server.[ch].
5155 * Removed function silc_server_command_send_users from the
5158 * Do not show topic on the client library anymore. The topic is
5159 sent in the command reply notify to the application and the
5160 application must show the topic now.
5162 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Added client searching by nickname hash into the IDENTIFY and
5165 WHOIS commands in the server as they were clearly missing from
5166 them. Affected file is silcd/command.c.
5168 * Fixed a bug in private message receiving in the client library.
5169 The remote ID was freed and it wasn't supposed, now it is
5172 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Minor fix to the channel payload; allocate the data area, as it
5175 needs to be of specific length.
5177 * If the key agreement port is zero then the operating
5178 system will define the bound port. Affected files are
5179 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5181 * Added new function silc_channel_payload_decrypt into the file
5182 lib/silccore/silcchannel.[ch].
5184 * Moved the channel message etc, check from silc_packet_decrypt
5185 to applications. The library calls now a generic
5186 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5187 when the packet is either normal or special. This was done to
5188 allow more wide range of checking that was not allowed when
5189 the code was in library. Now applications can do virtually any
5190 checks to the packet and return to the library the decision how
5191 the packet should be processed. Affected files are
5192 lib/silccore/silcpacket.[ch].
5194 Added silc_server_packet_decrypt_check to the server and
5195 silc_client_packet_decrypt_check to the client library.
5197 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5198 to send with specified source and destination information.
5200 * Channel message delivery between routers was broken after the
5201 channel key distribution was fixed earlier. The channel key
5202 was used be to distributed to other routers as well which is not
5203 allowed by the protocol. Now this is fixed and channel keys
5204 really are cell specific and the channel message delivery between
5205 routers comply with the protocol specification.
5207 * Fixed various commands in server to check also the global list
5208 for the channel entry and not just the local list. The affected
5209 file silcd/command.c.
5211 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added assert()s to buffer formatting and unformatting routines
5214 to assert (if --enable-debug) when error occurs. Affected
5215 file: lib/silcutil/silcbuffmt.c.
5217 * Changed to auto-reconnect to check whether the remote host is
5218 router and register the re-connect timeout if it is. It used
5219 to check that whether we are normal server, but router must do
5220 auto-reconnect with another router as well. Affected file
5223 * Removed the [<key len>] option from CMODE command as the cipher
5224 name decides the key length, nowadays. See the defined ciphers
5225 from the protocol specification.
5227 * Added [<hmac>] option to the CMODE command to define the HMAC
5228 for the channel. Added SILC_CMODE_HMAC channel mode.
5230 * Added [<hmac>] option for the JOIN command so that user can
5231 select which HMAC is used to compute the MACs of the channel
5234 * Added Hmac field to the Channel Message Payload. The integrity
5235 of plaintext channel messages are now protected by computing
5236 MAC of the message and attaching the MAC to the payload. The
5237 MAC is encrypted. Now, it is clear that this causes some
5238 overhead to the size of the packet but rationale for this is that
5239 now the receiver can verify whether the channel message decrypted
5240 correctly and also when private keys are set for the channel the
5241 receiver can decrypt the packet with several keys and check from
5242 the MAC which key decrypted the message correctly.
5244 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5245 lib/silccrypt/silccipher.[ch].
5247 * Added silc_hash_len to return the digest length into the
5248 lib/silcrypt/silchash.[ch].
5250 * Rewrote parts of Silc Channel Payload interface in the
5251 lib/silccore/silcchannel.[ch]. The encode function now also
5252 encrypts the packet and parse function decrypts it.
5254 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Fixed a minor formatting bug in the SKE's key material processing.
5257 It actually might have processed the keys wrong way resulting
5260 * Redefined the mandatory HMAC algorithms and added new algorithms.
5261 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5262 and hmac-md5 truncated to 96 bits. The mandatory is now
5263 hmac-sha1-96. Rest are optional (including the one that used
5264 to be mandatory). Rationale for this is that the truncated HMAC
5265 length is sufficient from security point of view and can actually
5266 make the attack against the HMAC harder. Also, the truncated
5267 HMAC causes less overhead to the packets. See the RFC2104 for
5270 * Added new [hmac] configuration section. The SKE used to use
5271 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5272 is of course wrong. The official names that must be proposed in
5273 the SKE are the ones defined in the protocol specification
5274 (hmac-sha1-96 for example). The user can configure any hmac
5275 using any hash function configured in the [hash] section. At
5276 least, the mandatory must be configured.
5278 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5280 * Added HMAC list to the SKE proposal list. It has now both
5281 hash algorithm list and HMAC list. This makes the protocol
5282 incompatible with previous versions. The SKE now seems to work
5283 the way it is supposed to work, for the first time actually.
5285 * Defined plain Hash algorithms to the protocol specification.
5288 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Implemented support for key agreement packets into the server.
5291 Added functions silc_server_key_agreement and
5292 silc_server_send_key_agreement. Other than these functions,
5293 server has nothing to do with this packet.
5295 * Added support for private message key packets into the server.
5296 Added functions silc_server_private_message_key and
5297 silc_server_send_private_message_key.
5301 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5302 called in the protocol's final callback instead in the END
5303 protocol state. This makes a little more sense and in the same
5304 time in client we can use the same protocol routines for normal
5305 key exchange and to key agreement packet handling as well.
5307 * Added to both client's and server's KE protocol context the
5308 SilcSKEKeyMaterial pointer to save the key material. We will
5309 bring the key material to the protocol's final callback by doing
5310 this. The final callback must free the key material.
5312 * Added SKE's packet_send callback into client's KE protocol
5313 context so that the caller can choose what packet sending function
5314 is used. This way we can use different packet sending when
5315 doing normal SKE when doing key agreement packet handling (in
5316 the key agreement packet handling we do not want to encrypt
5319 * Implemented the responder side of the key agreement routines
5320 in the client. The client can now bind to specified port and
5321 accept incoming key negotiation. The key material is passed
5322 to the application after the protocol is over.
5324 * Implemented the processing of incoming Key Agreement packet
5325 in the client. Added function silc_client_key_agreement to
5328 * Implemented the intiator side of the key agreement routines
5329 in the client. The client can now initiate key agreement with
5330 another remote client. The key material is passed to the
5331 application after the protocol is over.
5333 * Created client_keyagr.c to include all the key agreement
5336 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5337 SILC_TASK_CALLBACK except that it is not static.
5339 * Created client_notify.c and moved the Notify packet handling
5340 from the client.[ch] into that file.
5342 * Created client_prvmsg.c and moved all private message and
5343 private message key routines from the client.[ch] into that file.
5345 * Create client_channel.c and moved all channel message and
5346 channel private key routines from the client.[ch] into that file.
5348 * Changed silc_client_get_client_by_id_resolve to resolve with
5349 WHOIS command instead of IDENTIFY command, in the file
5350 lib/silclient/idlist.c.
5352 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Implemented the SKE's responder side to the Client library.
5356 * When FAILURE is received to the protocol do not trust it
5357 blindly. Register a timeout to wait whether the remote closes
5358 the connection as it should do it, only after that process the
5359 actual failure. This was changed to both client and server.
5361 * Added client_internal.h to include some of the structures
5362 there instead of client.h in lib/silcclient/.
5364 * Added function silc_task_unregister_by_callback to unregister
5365 timeouts by the callback function.
5367 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Some "Incomplete WHOIS info" errors has been appearing on the
5370 log files. Took away the entry->userinfo check from WHOIS
5371 reply sending. The entry->userinfo is now " " if client did not
5372 provide one. I thought this was fixed earlier but something
5373 is wrong still. Let's see if the error still appears.
5375 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Fixed a minor bug in the login when the channel key is
5378 re-generated in the server. It used to generate the key in
5379 wrong order and thus caused problems in the channel traffic.
5381 * Fixed a minor bug in channel key distsribution after
5382 KICK command. The key was not sent to the router even though
5385 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Added silc_ske_process_key_material_data as generic routine
5388 to process any key material as the SILC protocol dictates. The
5389 function is used by the actual SKE library but can be used by
5390 applications as well. This relates to the private message keys
5391 and the channel private keys since they must be processed the
5392 same way the normal SILC session keys. The protocol dictates
5393 this. Affected files: lib/silcske/silcske.[ch].
5395 Added also silc_ske_free_key_material to free the
5396 SilcSKEKeyMaterial structure.
5398 * Defined silc_cipher_set_key function to set the key for
5399 cipher without using the object's method function. The affected
5400 files: lib/silccrypt/silccipher.[ch].
5402 * Implemented silc silc_client_add_private_message_key,
5403 silc_client_add_private_message_key_ske,
5404 silc_client_del_private_message_key,
5405 silc_client_list_private_message_keys and
5406 silc_client_free_private_message_keys functions in the
5409 Added functions silc_client_send_private_message_key to send
5410 the Private Message Key payload and silc_client_private_message_key
5411 to handle incoming Private Message Key payload.
5413 * Added Cipher field to the Private Message Key payload to set
5414 the cipher to be used. If ignored, the default cipher defined
5415 in the SILC protocol (aes-256-cbc) is used.
5417 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Removed lib/silcclient/ops.h file.
5421 Redefined parts of the SILC Client Library API. Created new
5422 file silcapi.h that deprecates the ops.h file and defines the
5423 published Client Library API. Defined also private message key
5424 API and channel private key API into the file.
5426 This is the file that the application must include from the
5427 SILC Client Library. Other files need not be included by
5428 the application anymore.
5430 * Added new key_agreement client operation callback and also
5431 defined the Key Agreement library API for the application.
5433 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5436 is used by clients to request key negotiation between another
5437 client in the SILC network. If the negotiation is started it
5438 is performed using the SKE protocol. The result of the
5439 negotiation, the secret key material, can be used for example
5440 as private message key.
5442 Implemented the Key Agreement payload into the files
5443 lib/silccore/silauth.[ch].
5445 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Redefined ciphers for the SILC protocol. Added some new ciphers
5448 and defined the key lengths for the algorithms. Changed the
5449 code accordingly. The default key length is now 256 bits.
5451 * Fixed SKE key distribution function silc_ske_process_key_material
5452 when the key length is more than 128 bits. The default key
5453 length in SILC is now 256 bits.
5455 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5456 to indicate unsupported algorithm.
5458 * Renamed rijndael.c to aes.c and all functions as well.
5460 * Fixed a long standing channel key setting bug in client library.
5461 Weird that it has never surfaced before.
5463 * Fixed bug in channel deletion. If the entire channel is removed
5464 then it must also delete the references of the channel entry
5465 from the client's channel list as the client's channel entry and
5466 the channel's client entry share same memory.
5468 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Implemented CONNECT and SHUTDOWN commands in the client.
5472 * Implemented CLOSE command to the client.
5474 * Added the function silc_idlist_find_server_by_name into the
5475 files silcd/idlist.[ch].
5477 Added the function silc_idlist_find_server_by_conn into the
5478 files silcd/idlist.[ch].
5480 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * DIE command was renamed to SHUTDOWN. Updated the both code
5485 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5486 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5488 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5491 * Added function silc_server_create_connection function to create
5492 connection to remote router. My server implementation actually
5493 does not allow router to connect to normal server (it expects
5494 that normal server always initiates the connection to the router)
5495 so the CONNECT command is only good for connecting to another
5498 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5501 or some other client was kicked from the channel.
5503 Implemented the handling of the notify type to both client
5506 Implemented silc_server_send_notify_kicked to send the KICKED
5507 notify. It is used to send it to the server's primary router.
5509 * Implemented the KICK command into server and client.
5511 * Added `query' argument to the silc_idlist_get_client function
5512 to indicate whether to query the client from server or not if
5515 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5516 to indicate that the client is not channel founder.
5520 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Removed the rng context from SilcPacketContext structure and
5523 changed that the packet routine uses the Global RNG API.
5525 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Added support for quit message that client can "leave" on the
5528 channel when it quits the SILC. It is ditributed inside the
5529 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5531 Added silc_server_free_client_data that will take the
5532 signoff message as argument.
5534 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5536 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Updated parts of the protocol specification to keep it up
5541 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5544 payloads in one packet.
5546 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5547 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5548 use now the new List flag.
5550 * Also deprecated the following packet types: REPLACE_ID,
5551 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5553 * Added list support for Notify packet in server.
5555 * Added silc_server_send_notify_channel_change to send the
5556 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5557 the silc_server_send_replace_id.
5559 * Added silc_server_send_notify_nick_change to send the
5560 NICK_CHANGE notify type. Deprecates the function
5561 silc_server_send_replace_id.
5563 * Added silc_server_send_notify_join to send the JOIN notify type.
5564 Deprecates the function silc_server_send_new_channel_user.
5566 * Added silc_server_send_notify_leave to send LEAVE notify type.
5567 Deprecates the function silc_server_send_remove_channel_user.
5569 * Added silc_server_send_notify_cmode and
5570 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5571 types. Deprecates the silc_server_send_set_mode function.
5573 * Added SERVER_SIGNOFF notify type to indicate that server has
5574 quit. This means that all clients on the channel from that
5575 server will drop. This can be also used when netsplit happens.
5577 Deprecated REMOVE_ID packet type since it is not needed anymore
5580 Added silc_server_send_notify_server_signoff to send the
5581 SERVER_SIGNOFF notify type. Deprecates the function
5582 silc_server_send_remove_id.
5584 Added also silc_server_send_notify_signoff to send the
5585 SIGNOFF notify type.
5587 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5588 SILC protocol from this day on. Changed the protocol
5589 specification as well.
5591 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5592 notify type. It is used between routers to notify about
5593 topic changes on a channel.
5595 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5598 * Partly updated the protocol specification to comply with the
5599 changes now made. It is still though a bit outdated.
5601 * The JOIN notify type now takes one extra argument <Channel ID>.
5602 The packet used to be destined to the channel but now the
5603 JOIN type may be sent as list thus it is impossible to
5604 destine it to any specific channel. By adding this argument
5605 it is again possible.
5607 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added CREDITS file. The CHANGES and CREDITS file will appear
5610 in the distribution as well.
5612 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5615 types in the server's silcd/packet_receive.c.
5617 * Implemented CMODE and CUMODE to work in router environment.
5619 * Fixed minor encoding and decoding buglet from the
5620 lib/silccore/silcmode.c.
5622 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5625 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5627 * Changed all SilcConfigServer* and silc_config_server* to
5628 SilcServerConfig* and silc_server_config*, respectively.
5631 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Associated the ID (client or server ID) to the Authentication
5634 Payload to avoid any possibility of forging. Updated the
5635 protocol specification and the code accordingly.
5637 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * The RSA key length is now save to the RsaKey context in the
5640 key generation process in lib/silccrypt/rsa.c. The key length
5641 is now used to figure out the maximum size of the block allowed
5642 to be encrypted/signed.
5644 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5645 is equivalent to the silc_mp_mp2bin but does not allocate any
5648 * Changed silc_mp_mp2bin API to take length argument. If it is
5649 non-zero then the buffer is allocated that large. If zero, then
5650 the size is approximated using silc_mp_sizeinbase, which however
5653 * Created Global RNG API which is global RNG that application can
5654 initialize. After initializing, any routine anywhere in the
5655 code (including library) can use RNG without allocating a new
5656 RNG object. This was done to allow this sort of use of the
5657 RNG in code that has no chance to allocate RNG object. All
5658 applications currently allocate this and many routines in the
5659 library use this. Affected file lib/silccrypt/silcrng.[ch].
5661 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5662 it to use the Global RNG API.
5664 * Defined Authentication Payload into protocol specification that
5665 is used during SILC session to authenticate entities. It is
5666 used for example by client to authenticate itself to the server
5667 to obtain server operator privileges.
5669 Implemented this payload into the lib/silccore/silcauth.[ch].
5670 Implemented also routines for public key based authentication
5671 as the new protocol specification dictates.
5673 Moved definitions of different authentication methods from
5674 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5676 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5677 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5678 silc_pkcs_verify_with_hash functions into the file
5679 lib/silccrypt/silcpkcs.[ch].
5681 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5683 * The client entry's userinfo pointer must be always valid.
5684 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5685 will fail since it requires the userinfo. Now, the userinfo
5686 is allocated as "" if actual userinfo does not exist. Actually,
5687 it must exist and it is totally Ok to drop client connections
5688 that does not announce the userinfo. However, we will make
5689 this workaround for now.
5691 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5692 to return the remote port by socket.
5694 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5697 SILC_SERVER_PENDING_EXEC and added an new macro
5698 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5699 data or when error occurs while processing the pending command.
5701 Added new argument `destructor' into silc_server_command_pending
5702 and to the SilcServerCommandPending object. This destructor is
5703 now called after calling the pending callback or if error occurs
5704 immediately. If error occurs the actual pending callback won't
5705 be called at all - only the destructor. The destructor may be
5706 NULL if destructor is not needed.
5708 All this applies for client library code as well. Similar
5709 changes were made there as well for the pending commands.
5711 In the client, the application must now allocate the
5712 SilcClientCommandContext with the silc_client_command_alloc
5715 * Added reference counter to the SilcServerCommandContext. Added
5716 function silc_server_command_alloc and silc_server_command_dup
5719 Same type of functions added to the client library for the same
5722 * Removed the cmd_ident from IDListData away since it is now
5723 global for all connections. It is the command identifier used
5724 in command sending and with pending commands. The affected file
5727 * Added reference counter to the SilcSocketConnection objecet to
5728 indicate the usage count of the object. The object won't be
5729 freed untill the reference counter hits zero. Currently only
5730 server uses this, and client ignores it. The client must be
5731 set to use this too later. The affected files are
5732 lib/silccore/silcsockconn.[ch]. Added also the function
5733 silc_socket_dup to increase the reference counter.
5735 This was mainly added because it is possible that the socket
5736 is removed underneath of pending command or other async
5737 operation. Now it won't be free'd and proper DISCONNECTING
5738 flags, etc. can be set to avoid sending data to connection that
5739 is not valid anymore.
5741 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5742 the connection. After that it sets SILC_SET_DISCONNECTED.
5743 It is, however, possible that the socket data is not still freed.
5744 The silc_server_packet_process now checks that data is not
5745 read or written to connection that is DISCONNECTED. The socket
5746 get's freed when the reference counter hits zero.
5748 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Changed the client operation API: channel_message operation's
5751 `sender' is now the client entry of the sender, not the nickname
5752 and the `channel' is the channel entry, not the channel name.
5754 In the private_message operation the `sender' is now also the
5755 client entry of the sender not the nickname.
5757 Affected file is lib/silcclient/ops.h and all applications
5758 using the client operations.
5760 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Moved the calling of ops->connect() from connect_to_server_final
5763 into receive_new_id functin since that is the point when the
5764 client is actually allowed to send traffic to network. The
5765 affected file is lib/silcclient/client.c.
5767 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5770 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5771 (if needs broadcasting) instead of broadcasting the packets one
5772 by one which would make a burst in the network traffic.
5774 * Added `broadcast' argument to the functions in silcd/server.[ch]
5775 silc_server_create_new_channel[_with_id] to indicate whether
5776 to send New Channel packet to primary router.
5778 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Added new function into the silcd/server.[ch] files:
5781 silc_server_create_new_channel_with_id to create new channel with
5782 already existing Channel ID.
5784 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5785 lib/silccore/silcpacket.h. This packet is used t send list of
5786 Set Mode payloads inside one packet. Server uses this to set
5787 the modes for the channels and clients on those channels, that it
5788 announced to the router when it connected to it. The protocol
5789 specification has been updated accordingly.
5791 * The silc_server_new_channel did not handle the packet coming
5792 from normal server as it normally does not send that. However,
5793 when it announces its channels it does send it. Implemented
5794 the support for that.
5796 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5797 into the file lib/silccore/id.h.
5799 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Fixed memory leaks in the functions silc_idlist_del_client,
5802 silc_idlist_del_channel and silc_idlist_del_server in the file
5803 silcd/idlist.c. All of those leaked like a sieve.
5805 * Fixed some small memory leaks in the client's function
5806 silc_client_notify_by_server.
5808 * Added functions into silcd/server.c: silc_server_announce_clients,
5809 silc_server_announce_channels and silc_server_announce_server.
5810 These functions are used by normal and router server to announce
5811 to its primary router about clients, channels and servers (when
5812 router) that we own. This is done after we've connected to the
5815 These functions effectively implements the following packet types:
5816 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5817 and SILC_PACKET_NEW_ID_LIST.
5819 * Added new functions into the silcd/packet_receive.[ch]:
5820 silc_server_new_id_list, silc_server_new_channel_list and
5821 silc_server_new_channel_user_list to handle the incoming
5822 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5824 * Added support of changing Channel ID in the function
5825 silc_server_replace_id. If the server that announces a channel
5826 to the router already exists in the router (with same name but
5827 with different Channel ID), router is responsible to send
5828 Replace ID packet to the server and force the server to change
5829 the Channel ID to the one router has.
5831 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5832 client that the Channel ID has been changed by the router. The
5833 normal server sends this to the client. Client must start using
5834 the new Channel ID as the channel's ID.
5836 Implemented handling of this new type into lib/silcclient/client.c
5837 into the function silc_client_notify_by_server.
5839 * Added new function silc_idlist_replace_channel_id into the files
5840 silcd/idlist.[ch] to replace the Channel ID.
5842 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Call silc_server_command_identify_check always when processing
5845 the IDENTIFY command in silcd/command.c
5847 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5850 send keepalive packets. The packet can be sent by clients,
5851 servers and routers.
5853 Added function silc_socket_set_heartbeat into the file
5854 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5855 If not set, the heartbeat is not performed. The actual
5856 heartbeat is implemented in the low level socket connection
5857 library. However, application is responsible of actually
5860 Added silc_server_send_heartbeat to send the actual heartbeat
5861 packet into silcd/packet_send.[ch]. Server now performs
5862 keepalive with all connections.
5864 * Added silc_task_get_first function into lib/silcutil/silctask.c
5865 to return the timeout task with shortest timeout. There was a bug
5866 in task unregistration that caused problems. TODO has been
5867 updated to include that task system must be rewritten.
5869 * The client library will now resolve the client information when
5870 receiving JOIN notify from server for client that we know but
5871 have incomplete information.
5873 * Rewrote parts of silc_server_remove_from_channels and
5874 silc_server_remove_from_one_channel as they did not remove the
5875 channel in some circumstances even though they should've.
5877 * Encryption problem encountered in server:
5879 The LEAVE command used to send the Channel Key packet to the
5880 router immediately after generating it. However, the code
5881 had earlier sent Remove Channel user packet but not immediately,
5882 ie. it was put to queue. The order of packets in the router
5883 was that Channel Key packet was first and Remove Channel User
5884 packet was second, even though they were encrypted in the
5885 reverse order. For this reason, MAC check failed. Now, this
5886 is fixed by not sending the Channel Key packet immediately but
5887 putting it to queue. However, this is more fundamental problem:
5888 packets that are in queue should actually not be encrypted
5889 because packets that are sent immediately gets encrypted
5890 actually with wrong IV (and thus MAC check fails). So, packets
5891 that are in queue should be encrypted when they are sent to
5892 the wire and not when they put to the queue.
5894 However, the problem is that the current system has not been
5895 designed to work that way. Instead, the packet is encrypted
5896 as soon as possible and left to the queue. The queue is then
5897 just purged into wire. There won't be any fixes for this
5898 any time soon. So, the current semantic for packet sending
5901 o If you send packet to remote host and do not force the send
5902 (the packet will be in queue) then all subsequent packets to the
5903 same remote host must also be put to the queue. Only after the
5904 queue has been purged is it safe again to force the packet
5907 o If you send all packets immediately then it safe to send
5908 any of subsequent packets through the queue, however, after
5909 the first packet is put to queue then any subsequent packets
5910 must also be put to the queue.
5912 Follow these rules and everything works fine.
5914 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Added new function silc_server_remove_clients_by_server to
5917 remove all client entries from ID list when the server connection
5918 is lost. In this case it is also important to invalidate all
5919 client entires as they hold the invalid server entry. This
5920 fixes fatal bug when server has lost connection and will reconnect
5923 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Made some sanity checks to silc_server_daemonise like to check
5926 whether the requested user and group actually exists.
5928 * Added sanity check to SKE's silc_ske_responder_finish to check
5929 that the public and private key actually is valid.
5931 * Invalidate the client's nickname when receiving Replace ID
5932 packet and the Client ID is being replaced. This means that the
5933 server will query the nickname if someone needs it (client)
5936 * Sort the ID Cache in client library when the ID Cache data
5937 has changed (needs sorting).
5939 * Do not allow for SILC client to create several connections to
5940 several servers. The client does not support windows right now
5941 and generating multiple connections causes weird behaviour.
5943 Irssi-silc client does support windows and can handle several
5944 connections without problems, see: www.irssi.org and SILC plugin.
5946 * Fixed some places where client was added to the IDList. The
5947 rule of thumb is following (in order to get everything right):
5948 If the client is directly connected local client then the
5949 `connection' argument must be set and `router' argument must be
5950 NULL to silc_idlist_add_client function. If the client is not
5951 directly connected client then the `router' argument must
5952 bet set and the `connection' argument must be NULL to the
5953 silc_idlist_add_client function.
5955 * The funtion silc_server_packet_send_local_channel actually did
5956 not check whether the client was locally connected or not. It
5957 does that now. Fixed a bug related to LEAVE command.
5959 * Fixed Remove Channel User payload parsing bug in server's
5960 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5962 * The server's silc_server_save_channel_key now checks also the
5963 global ID list for the channel as it might not be in the local
5964 list. Fixed a bug related to LEAVE command.
5966 * Is this the end of the [<unknown>] buglet that has been lurking
5967 around for a long time? A little for loop fix in server's
5968 silc_server_command_whois_parse that is used by both IDENTIFY
5969 and WHOIS command. At least, this was a clear bug and a cause
5970 of one type of [<unknown>] buglet.
5972 * WHOIS and IDENTIFY commands call the function
5973 silc_server_command_[whois/identify]_check function even if
5974 we are not router server.
5976 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Added --with-gmp configuration option. If set the GMP
5979 is always compiled in the SILC source tree. If not set then
5980 it is checked whether the system has the GMP3 installed. If
5981 it has then the GMP won't be compiled (the system's headers
5982 and library is used), if it doesn't have it then the GMP is
5983 compiled in the SILC source tree.
5985 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5987 * Changed RSA private exponent generation to what PKCS #1
5988 suggests. We try to find the smallest possible d by doing
5989 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5990 not security fix but optimization.
5992 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Added new config entry [Identity] to fork the server and run
5995 it as specific user and group. A patch from Bostik.
5997 * Imported Dotconf configuration library into lib/dotconf.
5998 This will be used to create the SILC configuration files later.
5999 It will appear in the distsribution after this commit.
6001 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * A big code auditing weekend happening. Auditing code for
6004 obvious mistakes, bugs and errors. Also, removing any code
6007 Removed files for being obsolete:
6009 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6010 inline in the file lib/silcutil/silcbuffer.h)
6012 o lib/silcutil/silcbufutil.c (the header has inline versions)
6014 Changed code to fix possible error conditions:
6016 o The buffer formatting routines now check that the destination
6017 buffer really has enough space to add the data. This applies for
6018 both buffer formatting and unformatting
6019 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6020 unformatting was changed to accomodate following rules:
6021 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6022 sent to the function while XXX_*STRING will not allocate or copy
6023 the data into the buffer. Instead it sets the pointer from the
6024 buffer into the pointer sent as argument (XXX_*STRING used to
6025 require that the pointer must be allocated already). This change
6026 makes this whole thing a bit more consistent and more optimized
6027 (note that the data returned in the unformatting with XXX_*STRING
6028 must not be freed now). The routines return now -1 on error.
6030 o Tried to find all code that use buffer_format and buffer_unformat
6031 and added return value checking to prevent formatting and
6032 especially unformatting errors and possible subsequent fatal
6035 o Changed ske->x and ske->KEY to mallocated pointers in
6036 lib/silcske/silcske.h. Fixed possible data and memory leak.
6038 o Added return value checking to all *_parse* functions. Fixed
6039 many memory leaks as well.
6041 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6042 so that buffer overflows would not happen. All code now also
6043 checks the return value as it can fail.
6045 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Added reconnection support to server if the normal server looses
6048 its connection to the router (for example if router is rebooted).
6049 The server performs normal reconnection strategy implemented
6050 to the server. Affected file silcd/server.c.
6052 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Added new packet type SILC_PACKET_SET_MODE that is used to
6055 distribute the information about changed modes (for clients,
6056 channels and clients channel modes) to all routers in the
6057 network. Updated the protocol specification accordingly.
6059 Added functions into silcd/packet_send.c and
6060 silcd/packet_receive.c: silc_server_send_set_mode,
6061 silc_server_set_mode.
6063 Added new files silcmode.[ch] into lib/silccore that implements
6064 the encoding and decoding of Set Mode Payload. Added new type
6065 SilcSetModePayload. Moved the definitions of different modes
6066 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6068 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Oops, a little mistake in server's connection authentication
6071 protocol. The protocol is not ended with FAILURE but with
6072 SUCCESS if the authentication is Ok. :) Affected file is
6075 * Implemented NICK_CHANGE notify handling in server in the file
6076 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6077 the local clients on the channel. After the changing nickname
6078 in router environment snhould work and the [<unknown>] nickname
6079 should appear no more.
6081 The silc_server_replace_id function that receives the Replace ID
6082 payload now sends the NICK_CHANGE notify type also in the file
6083 silcd/packet_receive.c
6085 * Changed WHOIS and IDENTIFY command to support the maximum amount
6086 of arguments defined in protocol specs (3328 arguments). This
6087 fixed a bug that caused problems when there were more than three
6090 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6092 * Added extra parameter, command identifier, to the
6093 silc_client_send_command so that explicit command identifier
6096 Changed that ID list routines uses specific command identifier
6097 when sending WHOIS/IDENTIFY requests to the server so that they
6098 can be identified when the reply comes back.
6100 Affected files lib/silcclient/command.[ch],
6101 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6103 * Added `sender' argument to silc_server_packet_send_to_channel
6104 to indicaet the sender who originally sent the packet to us
6105 that we are now re-sending. Ignored if NULL. Affected file
6106 silcd/packet_send.[ch].
6108 * Added some server statistics support in silcd/server_internal.h
6109 SilcServerStatistics structure and around the server code. Also
6110 send some nice statistics information when client is connecting
6113 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Fixed channel ID decoding in server's JOIN command reply in
6116 silcd/command_reply.c
6118 * Fixed braodcasting of replace ID payload to not to send it if
6119 we are standalone server in silcd/packet_receive.c.
6121 * Fixed all channel message sending routines to not to send
6122 packets to clients that has router set, since they are routed
6123 separately in the same function earlier. Affects file
6124 silcd/packet_send.c and all channel packet sending functions.
6126 * In USERS reply, res_argv[i] are not allocated, the table
6127 is allocated. Thus changed that free the table, not its
6130 * In server's whois_check and identify_check if the client is
6131 locally connected do not send any WHOIS commands - they are not
6134 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Fixed some minor bugs in client when sending WHOIS command. The
6137 arguments was in wrong order.
6139 * Removed statis function add_to_channel from server in
6140 silcd/command.c that was previously used with the joining but
6143 * Tested USERS command in router environment successfully with two
6144 routers, two servers and two clients.
6146 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Reorganized the USERS command and command reply in client library
6149 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6150 When the command is given by user we register a pending command
6151 callback that will reprocess the command after the reply has been
6152 received from the server. When reprocessing the packet we then
6153 display the information. Thus, the USERS information is displayed
6154 now in the command callback instead of in the command reply
6155 callback. The processing of the command is same as previously
6156 when server has sent the command reply in the JOINing process.
6158 * Added to USERS command in silcd/command_reply.c to join the client,
6159 we didn't use to know about, to the channel after we've created
6160 a client entry for it. Also, for clienet we did know already still
6161 check whether it is on the channel or not and add it if not.
6163 * Removed silc_server_command_join_notify as the function and its
6166 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Changed the client's pending command handling to the same as the
6169 server's pending command handling. It is also now possible to
6170 execute command reply functions from other command reply
6171 function as the function callbacks for commands and command
6172 replies are one and same. The pending commands are not static
6173 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6174 in client connection context. Thus, pending commands are server
6175 connection specific as it is convenient.
6177 Changed the function silc_client_command_pending and
6178 silc_client_command_pending_del and added new function
6179 silc_client_command_pending_check. Removed the
6180 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6183 * Added cmd_ident, current command identifier, to the client
6184 connection context in lib/silcclient/client.h to keep track on
6185 command identifiers used in command sending. Client's command reply
6186 function handling now supports the mandatory command identifiers.
6188 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6189 funtions in client to fully support pending command callbacks.
6191 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6192 as one of the arguments to the application in the command reply
6195 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6196 before first releasing SILC but came back. Now it is removed again
6197 and should come back nomore. The FORWARDED flag was used only
6198 by the JOINing procedure by forwarding the command packet to router.
6199 Now, the JOINing procedure has been changed to more generic (due
6200 to various router environment issues) and FORWARDED is not needed
6201 anymore for anything. The protocol specification is yet to be
6204 Now, removed silc_server_packet_forward from server and the flag
6205 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6207 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Renamed NAMES command to USERS command. The NAMES was named that
6210 due to historical reasons. Now it is renamed. Also, rewrote
6211 parts of the USERS command. The nickname list is not sent anymore
6212 by the server. Only Client ID and mode lists are sent in the USERS
6213 command. Changed this also to the protocol specification.
6215 The client now resolves the names and stuff after it receives
6216 the USERS list from the server when joining to the channel.
6218 * WHOIS and IDENTIFY commands has been changed to support multiple
6219 Client ID's per command. One can now search for multiple users
6220 in the network by sending only one WHOIS or IDENTIFY command.
6221 Changed the code and the protocol specifications.
6223 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6224 uses silc_server_command_whois_parse to parse the request. */
6226 * If normal server, do not parse the WHOIS and IDENTIFY requests
6227 before sending it to the router. Saves some time.
6229 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Fixed JOIN command on client library. Wrong number of arguments
6232 used to crash the client.
6234 * Added silc_server_channel_has_global function to check whether
6235 channel has global users or not.
6237 * Added silc_server_channel_has_local function to check whether channel
6238 has locally connected clients on the channel.
6240 * The silc_server_remove_from_one_channel now checks whether the
6241 channel has global users or not after given client was removed from
6242 the channel. It also checks whether the channel has local clients
6243 on the channel anymore. If it does not have then the channel entry
6244 is removed as it is not needed anymore.
6246 * The silc_server_notify now checks on JOIN notify whether the joining
6247 client is one of locally connected or global. If it is global then
6248 the channel has now global users on the channel and that is marked
6249 to the channel entry. Also, it now saves the global client to
6250 global list who is joining and JOINs it to the channel. This is
6251 for normal server, that is.
6253 Changed silc_server_send_notify_on_channel,
6254 silc_server_packet_relay_to_channel and
6255 silc_server_packet_send_to_channel check if we are normal server
6256 and client has router set (ie. global client) do not send the
6257 message to that client, as it is already routed to our router.
6259 * Implemented LEAVE notify type handling in silc_server_notify
6262 * Tested LEAVE command in router environment successfully. Tested
6263 with two routers, two servers and two clients.
6267 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6269 * Implemented SIGNOFF notify type handling in silc_server_notify
6272 * silc_server_remove_id now removes the client entry from all channels
6273 it has joined and thusly sends SIGNOFF notify type.
6275 * Rewrote the NAMES list generation in server by removing two excess
6276 loops. The lists are created now inside one loop.
6278 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * silc_server_remove_channel_user checks now also global list
6281 for channel and client.
6283 * silc_server_new_channel_user checks now both local and global
6284 list for channel and client. Fixed a bug in client id decoding.
6285 Used to decode wrong buffer.
6287 * silc_server_channel_message checks now both local and global
6288 list for channel entry.
6290 * Tested channel joining (hence JOIN) in router environment
6291 successfully. Tested with two routers, two servers and two
6294 * Tested channel message sending in router environment successfully.
6296 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added silc_server_save_channel_key into server.[ch] to save the
6299 received channel key in Channel Key payload processing. It is
6300 also used in JOIN command reply handling.
6302 Equivalent function silc_client_save_channel_key added into
6303 client.[ch] into client library.
6305 * Changed JOIN command reply to send information whether the channel
6306 was created or not (is existing already) and the channel key
6307 payload. Changed protocol specs accordingly.
6309 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6310 the request was sent by ID and not by nickname. Crashed on
6313 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6316 now correctly save the received data.
6318 * silc_server_free_sock_user_data now notifies routers in the
6319 network about entities leaving the network.
6321 At the same time implemented functions silc_server_remove_id
6322 and silc_server_send_remove_id to receive and send REMOVE_ID
6323 packets. The packet is used to notify routers in the network
6324 about leaving entities. The ID removed will become invalid in
6327 * Added function silc_idlist_del_server into server. Removes and
6328 free's server entry from ID list.
6330 * silc_server_private_message function now checks, if we are router,
6331 that the destination ID really is valid ID, naturally.
6333 * In router when NEW_ID packet is received (for new client) the
6334 hash of the Client ID is saved in the ID Cache but the
6335 client->nickname is set to NULL, instead of putting the hash
6338 IDENTIFY command now also checks that client->nickname must be
6339 valid. If it is not if will request the data from the server who
6340 owns the client. Added new function
6341 silc_server_command_identify_check.
6343 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6344 to set the command to already allocated Command Payload.
6346 * Tested private message sending in router environment with two
6347 routers, two servers and two clients. Fixed minor bugs and now
6350 * Fixed segfault from client's NAMES command. Used to crash if
6353 * Forwarded packets must not be routed even if it is not destined
6354 to the receiver. Changed server code comply with this.
6356 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Added `require_reverse_mapping' boolean value to ServerParams
6359 structure. If TRUE (not default) the server will require that
6360 the connecting host has fully qualified domain name.
6362 If the reverse mapping is not required and hostname could not be
6363 found the IP address is used as hostname.
6365 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Implemented version string checking to both client and server.
6368 The check is incomplete currently due to the abnormal version
6369 strings used in development version of SILC.
6371 * Changed all command functions in server to use the new
6374 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Changed char *data to unsigned char *data in ID Cache system to
6377 support binary data as ID Cache data. Changed code to support
6378 binary data in lib/silccore/idcache.c.
6380 * Renamed silc_server_packet_relay_command_reply to
6381 silc_server_command_reply as it is normal packet receiving
6382 function. Rewrote the function to accept command replys for
6383 servers and not only for clients.
6385 * Mark remote router always as registered server if we are connecting
6386 to it. Otherwise, commands sent by the router to us are ignored.
6388 * All ID List find routines now returns the ID Cache Entry pointer
6389 as well if requested.
6391 * WHOIS command works now in router environment, tested with two
6392 routers, two servers and two clients.
6394 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6395 in router environment (as it is almost equivalent to WHOIS) but
6396 hasn't been tested thoroughly. Added new functions:
6398 silc_server_command_identify_parse
6399 silc_server_command_identify_send_reply
6400 silc_server_command_identify_from_client
6401 silc_server_command_identify_from_server
6403 * Disabled route cache adding because adding two different ID's with
6404 same IP replaces the old cache entry thus giving wrong route.
6405 The entry->router->connection is always the fastest route anyway
6406 so route cache may not be needed. Of course, new routes maybe
6407 established after receiving the ID when the entry->router->connection
6408 might not be anymore the most optimal.
6410 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Add route cache for received ID for fast routing.
6414 * Added silc_server_packet_route to route received packet on router
6415 that is not destined to us.
6417 * Renamed silc_server_get_route to silc_server_route_get.
6419 * Added id_string and id_string_len fields into SilcServer to
6420 include encoded ServerID for fast comparing without excess
6421 encoding of the ID's.
6423 * Cleaned up WHOIS command on server side. Added following static
6426 silc_server_command_whois_parse
6427 silc_server_command_whois_check
6428 silc_server_command_whois_send_reply
6429 silc_server_command_whois_from_client
6430 silc_server_command_whois_from_server
6432 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6433 arguments in command replies. All command functions should be
6434 updated to use this macro.
6436 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Minor typo fixes on command reply handling on server.
6440 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6442 * Added silc_server_command_add_to_channel internal routine to add
6443 the client to the channel after router has created the channel and
6444 sent command reply to the server.
6446 * Added generic silc_server_send_command to send any command from
6449 * Use static buffer with ID rendering instead of duplicating data.
6451 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * Fixed a channel user mode bug when joining to a channel server gave
6454 everybody channel founder rights, oops.
6456 * We mark ourselves as the router of the incoming server connection
6457 if we are router ourselves. This way we can check in some packet
6458 sending functions whether it is locally connected server. For
6459 incoming router connections we put NULL.
6461 * For router sending packets locally means now always sending the
6462 packet cell wide; to local clients and local servers. For normal
6463 server sending packet locally means sending it to only local
6466 * Fixed the JOIN command to really work in router environment. If the
6467 channel is created it is always created by the router. Router is
6468 also responsible of making the initial joining to the channel,
6469 sending JOIN notify to the sending server and distributing
6470 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6471 does not exist server doesn't do anything else but forward the
6472 command to the router which performs everything.
6474 * Added silc_server_send_channel_key function to send the Channel Key
6477 * Added silc_server_create_channel_key to create new channel key. The
6478 channel key is now re-generated everytime someone joins or leaves
6479 a channel, as protocol dictates. Note: channel->key_len is the
6482 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6485 packet_receive.[ch] to separate packet sending and receiving
6486 routines. The server.[ch] now includes everything else including
6487 actual packet processing (writing and reading data) and other
6490 Renamed silc_server_private_message_send_internal to
6491 silc_server_send_private_message. The routine is still though
6492 used only to relay private messages as server does not send
6493 private messages itself.
6495 Renamed silc_server_new_channel to silc_server_create_new_channel
6496 and added new function sicl_server_new_channel that handles the
6497 incoming New Channel packet. Added also new sending function
6498 silc_server_send_new_channel to send New Channel Payload.
6500 * Added new function silc_server_notify to process incoming notify
6501 packet to the server/router. Server may then relay the notify
6502 to clients if needed.
6504 * Added new function silc_server_new_channel_user to process incoming
6505 New Channel User packet. Router will redistribute the packet and
6506 send JOIN notify to its local clients and locally connected servers
6507 if needed. Normal server will send JOIN notify to its local client
6508 on same channel when received this packet. Added also corresponding
6509 sending function silc_server_send_new_channel_user to sent the
6512 * Added boolean route argument to send_notif_to_channel and
6513 packet_send_to_channel functions to attempt to route the packet
6514 if it is TRUE and send only locally if it is FALSE.
6516 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * silc_server_replace_id now broadcasts the received replace ID
6519 packet if it is not broadcast packet already. The router must
6520 broadcast to inform other routers about changed ID.
6522 * Added backpointer to server's router into SilcServer context in
6523 silcd/server_internal.h.
6525 * Fixed silc_server_packet_broadcast to send correct broadcast
6528 * The channel key is now distributed to the local client as soon
6529 as it is received from the router (in router environment) so that
6530 no other packet may be sent for the channel until client has
6533 * silc_server_remove_channel_user now broadcasts the received
6534 Remove Channel User packet if it is not broadcast packet already.
6535 The router must broadcast to inform other routers about removed
6538 * Added users field into SilcPacketContext that is a reference count
6539 of the context. One can increase the reference count by calling
6540 silc_packet_context_dup which is now changed to just increase the
6541 reference count instead of duplicating the data. The reference
6542 count is decresed by calling silc_packet_context_free that will
6543 free the data after the reference count hits zero.
6545 For now on the packet context and everything allocated into it
6546 (including the raw packet from network) must be freed by calling
6547 the new silc_packet_context_free function. Added also new function
6548 silc_packet_context_alloc that must be used now to allocate the
6549 context. This also means that if a routine is asynchronous from
6550 silc_[client/server]_packet_parse_type the packet context must
6551 be duplicated by calling silc_packet_context_dup. Otherwise it
6552 gets free'd after silc_[client/server]_packet_parse_type returns.
6553 Also, one must remember that if packet is duplicated then its
6554 reference count must be decresed by calling the free function as
6555 many times as it was duplicated.
6557 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6558 from both client and server.
6560 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Made joining to a channel working in router environment.
6564 * Cleaned up JOIN command on server side and create function
6565 silc_server_command_join_channel internal routine to make the
6568 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Changed silc_command_pending list to SilcDList. Also, added
6571 `ident' field to SilcServerCommandPending structure to identify
6572 the reply and to call correct callback.
6574 Added silc_server_command_pending_check function to replace the
6575 corresnponding macro. The silc_command_pending list is not
6578 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6579 to set identifier to previously allocated Command Payload. It
6580 is used to set identifier for command when resending Command
6583 * Added silc_command_payload_encode_payload to encode Command
6584 Payload buffer from SilcCommandPayload structure.
6586 * Added silc_argument_payload_encode_payload to encode Argument
6587 payload buffer from SilcArgumentPayload structure.
6589 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Changed WHOIS command to support router connection on server side.
6592 The whois request is always sent to router unless the server is
6593 standalone server. After server has received the reply from the
6594 router will it send the reply to the client.
6596 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6597 broadcast received broadcast packet. The function is used only
6598 by router. The broadcast packet is always sent to the router's
6601 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6602 render given ID to printable string, for log files for example.
6604 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Made basic router to router connections working. At least they
6607 can now connect to each other but nothing really works the way
6608 they are supposed - yet.
6610 * Added new initiator token to RouterConnection configuration
6611 file in silcd/serverconfig.[ch]. It is used to tell whether we
6612 are the initiator to the remote router or whether we'll expect
6613 the other end to connect.
6615 * Moved registering of listener task to silc_server_init, hence
6616 the server starts listenning as soon as it is run, even if it
6617 does not have connections to other routers. Let's see how well
6620 * Changed default connection retry timeouts for more suitable in
6623 * Removed cipher and such arguments from silc_idlist_add_client
6624 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6625 Added new function silc_idlist_add_data to add the keys and stuff
6628 * Added SilcIDListData structure and added it to SilcClientEntry
6629 and SilcServerEntry as their first field in the structure. This
6630 way we can explicitly cast the ID entries to the SilcIDListData
6631 structure and get common data for the entries. In past, we had
6632 to first check what type of connection it is and then cast it to
6633 correct ID entry type. Now, we can directly cast the opaque
6634 pointer to the SilcIDListData (no matter what ID entry it actually
6635 is) and get the data needed.
6637 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6640 in some circumstances even if threre were timeout tasks, though not
6641 IO tasks, but tasks anyway. Now fixed.
6643 * Defined SilcServerConnection structure to hold connection specific
6644 stuff about directly connected servers and routers. The definition
6645 is currently in silcd/server_internal.h. I thought about having
6646 a bit more important role fro this struct but for now it is used
6647 only when connecting to other server (or router actually).
6649 * Added connecting retry support in server when connecting to
6650 router(s). The retry feature implement exponential backoff
6651 algorithm. Also, added SilcServerParams structure to hold default
6652 parameters for server. For now, it include these retry settings
6653 and are hard coded. After server is moded to be as Silc Server
6654 Library this structure will be more important.
6656 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Changed client librarys channel->clients table to SilcList and
6659 changed code accordingly.
6661 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Changed client's channel table to SilcList and changed code
6664 accordingly. Also changed SilcChannelClientEntry to include back-
6665 pointer to the channel so that client entry can use that structure
6666 as list as well and we have fast cross-reference to the channel.
6667 This change dramatically decreased the complexity of channel
6668 handling with client entry and vice versa (removed one extra
6669 loop when searching for channel entry from many functions).
6671 * Changed server->sim from table to SilcDList and changed code
6674 * NAMES command can now be used from user interface. It will show
6675 the user list on the channel, neatly.
6677 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6678 Code now saves realname of the user if it becomes available.
6680 * Renamed configure.in to configure.in.pre and made ./prepare
6681 script to automatically add correct version string to
6682 configure.in which it creates from configure.in.pre.
6684 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * NAMES command reply now shows users mode with the nickname when
6689 * Moved silc_client_ch[u]mode[_char] functions from
6690 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6691 place sucks, they are utility functions and should be in some
6694 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6696 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6699 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Added TRQ (efficient deque and list library) into lib/trq. This is
6704 a very good list library that is currently used in the SILC. Defined
6705 SilcList API over the library because I didn't like the API very
6706 much. See lib/trq/silclist.h for the API and examples of how to
6707 use the API. Fixed various places in the code to use the new
6708 SilcList API. The SilcList is meant for lists that has a structure
6709 already defined as a list. It is not suitable to add just some
6710 context to the list (in TRQ, the context is the list actually).
6712 So, I defined SilcDList that can be used for the purpose where
6713 predefined list structure does not exit. This can be used as
6714 such list. Now some context just can be added to the SilcDList.
6715 Currently this list is not used in the SILC just yet, though there
6716 are a lot places where this can replace dynamically allocated
6717 tables and I will fix these places, later, to use SilcDList.
6718 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6719 and use TRQ internally).
6721 Also fixed some annoying warning messages that the original TRQ
6722 code generated. Also minor changes to TRQ's Makefile.in.
6724 * Added support for querying by Client ID to both WHOIS and
6725 IDENTIFY commands into server, as required by the protocol.
6727 * Removed method function pointers from SilcBuffer structure. They
6728 weren't used to anything and just increased the context size for
6729 no good reason. This change also made silc_buffer_alloc and
6730 silc_buffer_free functions inline functions.
6732 * Disabled command flooding detection support until it's fixed so
6733 that it accepts commands in but does not execute them more than once
6736 * Added silc_net_localhost(), to return local hostname, into
6737 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6738 that must be initialized before calling silc_client_init.
6740 * Added new function: silc_server_send_notify_on_channels to send
6741 notify messages to all channels client has joined. It is assured
6742 that the message is sent only once per client.
6744 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6745 lib/silcutil/silcutil.[ch] as silc_format function. The new
6746 function is generic and is used by server as well, not only by
6747 the logging routines.
6749 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6750 the provided version string was not acceptable. Added new function:
6751 silc_ske_check_version into lib/silcske/silcske.h. The function
6752 must be implemented by the application (client or server) and it
6753 does not reside in the SKE library. The function checks the version
6754 string remote end sent.
6756 * Added back pointers (to opaque context and to SilcSocketConnection)
6757 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6759 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6760 duplicate packet context structure.
6762 * Changed `notify' client operation to send same arguments as client
6763 receives from server except for ID's. ID's are mapped to correct
6764 ID entry and that is returned. Also, if channel entry is not sent
6765 by server but the notify is for channel the channel entry is sent
6766 to application (otherwise application doesn't know that it is for
6767 channel (library gets it from packet's Destination ID)).
6769 * Added silc_client_remove_from_channels into client library to
6770 remove a client from all channels it has joined to. Used when
6771 received SIGNOFF notify from server. Added also new function
6772 silc_client_replace_from_channels to replace old ID entry with
6773 new ID entry on all channels. Used when received NICK_CHANGE
6776 * Fixed ID Cache list handling in silc_idlist_get_client in
6777 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6778 to get (or query) client by ID.
6780 * Updated TODO list.
6782 * Added connection authentication status message defined by the
6783 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6784 support for these into the code in client and server side.
6786 * Added generic function silc_client_send_command to send any command
6787 with variable argument list. Application should use this function
6788 to send commands if the command functions provided by the library
6789 does not suite for the application's user interface needs.
6791 * Added new `failure' client operation. Application is notified about
6792 received failure packet if client is executing a protocol. In this
6793 case the protocol's execution has failed.
6795 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6796 is required by the protocol.
6798 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6799 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6802 * Added status flag to SilcSKE object to indicate realtime status
6803 of the SKE protocol.
6805 * Application receives now exactly same command reply arguments as
6806 the library receives from server. However, if ID is received the
6807 corresponding ID entry is returned to the application (eg. Client
6808 ID is mapped to correct SilcClientEntry entry and that is returned).
6809 Changed command_reply client operation due to this change.
6811 * Changed all ID's in commands and in command replys as ID Payloads.
6812 Change affected both client and server side codes.
6814 All ID's sent in SILC network (with execption of ID's in SILC
6815 Packet header) are sent in ID Payload to support variable length
6818 * Server now notifies nick changes and notifies all clients on
6819 the channels about the new nickname (about the new Client ID,
6822 * Implemented CMODE command to change channel modes. Supports all
6823 channel modes defined by the protocol specs except ban and invite
6824 lists. (Also, private channel key mode is supported but support for
6825 setting private channel key in client is missing, thus, this mode
6826 has no effect on client side (except that server requires that the
6827 client uses private channel key and normal channel traffic does not
6830 Also, invite mode works per se, but INVITE command does not work
6831 yet correctly, so you can set channel as invite only channel but
6832 inviting clients to the channel does not work (it is yet to be
6833 thought what's the best way to do it).
6835 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6836 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6837 Implemented CUMODE command to change user's mode on the channel.
6838 Supports all modes defined by the protocol specs.
6840 * Added NAMES command reply to return users modes on the channel.
6842 * Removed unnecessary and slow ciphers from lib/silccrypt.
6844 * Set SO_KEEPALIVE option to connection sockets by default.
6846 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6848 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6849 redefined the Notify Payload into protocol specs.
6851 * Added silc_id_payload_parse_id to get ID directly from raw
6854 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6857 accept searching by Client ID as well.
6859 * Added support for LEAVE and SIGNOFF notify types in client library.
6861 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6862 to parse ID Payload from raw data.
6864 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Added flags parameter into silc_ske_assemble_security_properties
6867 function in lib/silcske/silcske.[ch].
6869 * Changed notify client operation to fit better for notify messages
6870 sent by server. The notify payload received from server is now
6871 passed to the application (after parsing it to SilcNotifyPayload).
6872 It is application's responsibility to retrieve the arguments
6873 from the payload and show the message the way it wants. The message
6874 sent by server is implementation specific.
6876 * Changed public keys to comply with the protocol specification.
6877 Old public keys are not supported anymore and are not compatible.
6879 * Removed nickname from Channel Payload as the latest draft removed
6880 it. The client must resolve the nickname from the NAMES command
6881 reply received when it joined the channel.
6883 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6885 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Fixed some errors in protocol specification drafts.
6889 * Created lib/silccore/silcnotify.c to implement Notify Payload
6890 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6891 generic payloads described by protocol specifications. The file
6892 includes implementations for ID Payload and Argument Payload.
6894 * Changed Command Payload implementation to use the new Argument
6895 Payload. Changed command_xxxx_payload to command_payload_xxxx
6896 to comply with SILC coding conventions.
6898 * Added suppport for Argument Payload handling in Notify Payload
6899 implementation as protocol requires it. Added the new support
6900 into server and client lib as well.
6902 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6904 * Added support for multiple nicknames on same channel. [n] is
6905 added locally to the nickname if there are more than one same
6906 nicknames on the channel.
6908 * Server now sends all nicknames that matched WHOIS request.
6909 Client also shows the list received from server.
6911 * Added TOPIC command to client side. User can now set and show
6912 current topic on channel.
6914 * Added MOTD command to client and server. Also, server sends the
6915 motd when client connects to the server.
6917 * Changed version strings to comply ISO 8601.
6919 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Fixed protocol error handling in client library. It should now
6922 cope even if the SKE fails for some reason.
6924 * Made new protocol specification drafts for submitting to IETF.
6926 * Implemented TOPIC command to server in silcd/command.c.
6928 * Added two new notify types into lib/silccore/silcnotify.h:
6929 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6930 notify nickname change and topic setting/change on a channel.
6932 * API change of command_reply operation in client library. The
6933 application gets now the status type received from server as well.
6935 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6939 * Cras fixed and optimized the packet handling even further and
6940 it should work now. Minor change to the prototype of function
6941 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6943 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Added new function into lib/silcutil/silcschedule.[ch]:
6946 silc_schedule_with_fd to select() a specified fd. The function
6947 returns after timeout expires or data arrives or goes. The
6948 function is used by packet routines to wait that all data is
6949 received from network.
6951 * Fixed data reading from network in lib/silccore/silcpacket.c.
6952 The code now assures that all data is read from the fd and then
6953 continues packet processing. This was a bug fix since the code
6954 used to drop some data in some circumstances.
6956 * Added new function into lib/silcclient/client.[ch]:
6957 silc_client_start_key_exchange to start key exchange after
6958 connection has been established to server. The code internally
6959 now uses this funtion but its main purpose was to provide it
6960 for applications that perform their own connecting. After
6961 application has created a connection it merely calls this
6962 function to start the key exchange between client and server.
6963 The library takes care of everything else after that.
6965 Updated also lib/silcclient/README to explain the usage of
6968 * Do not send to application information that connection has
6969 been established. Application gets notified it by connect
6972 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Applied cras's patch to add silc_schedule_one function. The
6975 function runs scheduler once and returns.
6977 * Fixed the scheduler after cras messed it up. The timeout
6978 handling works now as it's supposed to work.
6980 * Added into lib/silccore/ silcnotify.h to include notify
6981 message types support. Changed silc_server_send_notify*
6982 functions, in server.[ch], to support those new notify types.
6983 Added the support for the notify types into client library,
6984 as well. Added new notify client operation into ops.h in
6987 * Changed silc_server_packet_send_to_channel to send normal
6988 packets instead of just channel message packets. The function
6989 is now used to send the notify packets to channels. It is not
6990 used to send channel message packets anymore, as server never
6993 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6994 va_arg()s as it seems to require it nowadays. I guess, if SILC
6995 is compiled with older va_arg() the new code should work anyway.
6997 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6999 * Splitted core library. Core library (lib/silccore) includes
7000 now only SILC protocol specific core (and common) components.
7001 Created new utility library (lib/silcutil) that includes more
7002 generic purpose stuff. The stuff for util library was taken
7003 from the old core library. This was minor and easy split.
7005 * Created SILC Client Library (lib/silcclient) that includes
7006 implementation of the SILC client without user interface. This
7007 was major move from silc/ directory. The code has been changed
7008 so that it is transparent towards the user interface. The
7009 silc/ directory includes now the same user interface as before
7010 and it uses the new client library. Read lib/silcclient/README.
7011 Basicly, the client library performs everything else related
7012 to SILC except user interface handling. Also, configuration
7013 files are considered to be part of user interface and library
7014 does not handle them.
7016 This change also changed a lot of structures, function naming etc.
7017 Most important change was that SilcClientWindow object was
7018 renamed to SilcClientConnection in the client library. Created
7019 also new file lib/silcclient/ops.h. Also added new files
7020 silc/local_command.[ch] and silc/client_ops.[ch].
7022 All these changes were made to make it easier for user interface
7023 designers to create what ever user interface for the SILC client
7026 It is also expected that the server will be moved to lib
7027 directory as well and SILC Server Library will be created;
7028 sometimes in the future.
7030 * Removed Local commands from lib/silccore/silccommand.h as
7031 they are application specific and new client library does not
7032 handle any of those anymore.
7034 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7035 old client implementation in silc/.
7037 * Added support for callback functions in SILC_LOG_* macros.
7038 Application can now set its own callbacks that will be called
7039 instead of using the default functions that will always print
7040 the debug messages to stderr (or stdout). Also, debugging can
7041 now be disabled by setting silc_debug to FALSE and re-enabled by
7042 setting it to TRUE. Note, that logging will still work even
7043 if debugging is disabled.
7045 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7046 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7047 silc_log_reset_debug_callbacks.
7049 * To enable debugging in silc client one must give now -d
7050 option on command line.
7052 * Changed silc_schedule_init to automatically allocate task queues
7053 if they are not allocated before calling it.
7055 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Added GMP 3.1 into math library.
7059 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7062 a channel in SILC network. The packet is used by servers and
7063 routers to notify other routers that user has left a channel.
7064 This little feature was missing until now. Added the feature
7065 to protocol specification as well.
7067 Added functions: silc_server_send_remove_channel_user and
7068 silc_server_remove_channel_user into server.[ch].
7070 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7071 lib/silccore/silcpacket.h. However, they are not implemented
7074 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7076 * Fixed joining to a channel and sending channel messages
7077 between server and router. The channel message sending should
7078 now work inside a cell.
7080 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7082 * Fixed the private message sending between server and router.
7083 The private message sending should now work inside a cell.
7085 * Added silc_server_replace_id into server.[ch] to replace
7086 existing ID in the SILC network.
7088 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7089 and silc_idlist_replace_server_id into idlist.[ch] in server.
7091 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Fixed the server to server connections. Server can again now
7094 connect to router. Router to router connections probably does
7097 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Added dynamic protocol registering support. Now protocols can
7100 registered and unregistered on the fly. Patch by cras.
7102 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Added lib/contrib directory to hold routines that some platforms
7105 don't have but are needed by SILC.
7107 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7108 into lin/contrib to provide getopt() and getopt_long() for
7109 those who don't have it.
7111 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * Added AWAY command to client. When away message is set and
7114 client receives a private message packet the client automatically
7115 replies to the sender with the away message.
7117 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7118 bug seemed to be the cause of recent problems when compiling
7121 * Added version detection support to SKE protocol specification
7122 and added the new changes to the SKE implementation as well.
7123 There were other minor changes in the SKE protocol as well.
7125 Many changes in lib/silcske/silcske.[ch] and in
7126 lib/silcske/payload.[ch].
7128 * Added ^U functionality, clear input line. Patch from cras.
7130 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Mainly small bugfixes on core library. Fixed some debugging
7133 logging and buffer overflow in silclog.c.
7135 * Updated config.sub and config.guess on the distribution tree.
7137 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Added command lagging support in server. Client may execute
7140 commands now only once in two seconds.
7142 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Optimized packet reception. MAC computation and checking is now
7145 also more optimized. A lot previously duplicated code is now
7146 used as generic by both client and server.
7148 * Fixed key pair generation in clientutil.c
7150 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added into lib/silccore/silcbufutil.[ch] new function;
7153 silc_buffer_realloc.
7155 * Moved generic packet sending/encryption functions to
7156 lib/silccore/silcpacket.[ch] from client and server. Some
7157 rewriting of the functions.
7159 * Moved all generic packet reception/decryption functions to
7160 lib/silccore/silcpacket.[ch] from client and server. The
7161 packet processing is now much cleaner in both client and server.
7162 These were major changes in both client and server.
7164 * Created many common functions in server to do packet sending.
7165 Previously code were duplicated a lot, this has been removed
7168 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7170 * Rewrote major parts of the ID cache system. Don't know
7171 whether it is better now or not but at least the API is more
7174 * Major rewrite on ID cache stuff on client because of the ID
7175 cache API changes. Added idlist.c to client.
7177 * Also major rewrite on ID cache stuff on server as well.
7178 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7179 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7180 in hand, instead they are all put into the ID cache system now.
7181 All server_idlist_* routines uses ID cache now instead of
7182 traversing its own lists (those lists does not exist anymore).
7183 SilcIDList though still exists. Also, SilcXXXEntry's are
7186 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7188 * Finally made the SKE implementation compliant to the protocol
7189 specification. All mp integers are now binary encoded as
7190 opposed being HEX encoded.
7192 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7195 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7196 functions: silc_[encode/decode]_pem. Also added function
7197 silc_encode_pem_file to PEM encode with newlines ('\n') for
7200 * SILC public keys are now encoded either PEM or binary. Same
7201 option is for private keys as well. By default private keys
7202 are binary encoded and public keys PEM encoded. Silly HEX
7203 encoding were removed.
7205 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7206 function to create fingerprints.
7208 * Fixed a bug in SHA1; does not change the original data anymore.
7210 * Partly implemented INFO command on client and server side.
7211 Fixed CLEAR command. Changes to SERVER command; show current
7212 server(s) when giving command without arguments. Added
7213 VERSION command to client.
7215 * Added check to server that unregistered connections cannot
7216 execute commands (unless it is specificly allowed).
7218 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Fixed screen refresh.
7222 * Fixed channel joining bug from client. On some circumstances
7223 client tried to join to a channel it had already joined.
7225 * Added public key verification process into client's protocol.c.
7226 The client now verifies the public key from user and saves
7227 it into ~./silc/serverkeys/ directory.
7229 Added into: clientutil.[ch]: silc_client_verify_server_key.
7231 * Changed SKE protocol's silc_ske_initiator_finish function
7232 to accept callback function that verifies the received public
7233 key. Removed old silc_ske_verify_public_key function.
7235 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7238 silc_pkcs_private_key[_data]_set.
7240 * Made the password and public authentication more cleaner in
7241 server's protocol.c.
7243 * Removed historic and obsolete protocol `channel_auth' from
7244 both client and server.
7246 * Removed wrong way of sending command status messages from
7247 server to client in server's command.c. The old way violated
7248 protocol specification.
7250 Changes to silccore/silccommand.[ch]: removed
7251 silc_command_encode_status_payload -> not needed anymore,
7252 changed silc_command_encode_payload_va to accept extra
7253 argument on variable argument list. The argument type must
7254 now be provided to the function. Also, added new function:
7255 silc_command_encode_reply_payload_va which is same as
7256 normal command_encode_payload_va except command status type
7257 is provided as extra argument.
7259 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Added ~./silc directory handling. The directory includes the
7262 public and private keys for the client.
7264 Added silc_client_check_silc_dir, silc_client_create_identifier
7265 and silc_client_load_keys.
7267 * Implemented SILC protocol compliant public key. Added public
7268 and private key saving to and loading from files.
7270 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7271 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7272 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7273 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7274 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7276 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7277 silc_pkcs_load_[public/private]_key.
7279 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Added silc_server_get_route (route.[ch]) to get connection
7282 data for the fastest route for given ID.
7284 * Implemented INVITE command on client and server. The command
7285 were re-defined in the SILC Protocol Specification and the
7286 implementation now complies with the specification.
7288 * Implemented PING command on client and server.
7290 * Implemented NAMES command on client and server. The server side
7291 supports currently only normal server not router server yet.
7292 Some changes to NAMES definition in SILC protocol specification.
7294 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7296 * Implemented LEAVE command on client and server.
7298 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7299 again. This change was made to the protocol as well. Server
7300 should not violate the protocol specification anymore.
7302 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7305 was tested. SOCKS4 was not but should work anyway.
