80 old name went against naming convention. Applications now
81 include "silcclient.h" instead of "clientlibincludes.h".
82 Removed includes/clientlibincludes.h, it is redundant now.
84 * Renamed includes/version.h to silcversion.h.
86 * Added really preliminary support for OS/2 into the util
87 library. Only thread & mutex API is implemented, others

139 Affected file lib/silcclient/client.c.
141 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
143 * ROBOdoc documented the lib/silcske/silcske.h, and improved
144 the SKE interface a bit.
146 * Fixed padding problem in PKCS#1. The padding was not actually
147 random since the random number generator was used incorrectly.
148 This security bug affects only when encrypting with PKCS#1, and
149 it is not currently used at all in SILC. SILC only use signing
150 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

231 algorithm parts and created new file silcalgs.conf, that
232 is now included from the example_silcd.conf.in.
234 * Optimized the silc_server_connect_to_router_second to take
235 the connection configuration object from the SilcServerConnection
236 object instead of finding it during the connecting phase.
237 Added the configuration object to SilcServerConnection struct.
238 Affected files silcd/server_internal.h, server.c.

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

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

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

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

401 lib/silcclient/idlist.[ch].
403 * Fixed a bug in hash table tarversing. While the hash table
404 is traversed with SilcHashTableList the table must not be
405 rehashed. It is now guaranteed that auto rehashable tables
406 are not rehashed while tarversing the list. Also defined that
407 silc_hash_table_rehash must not be called while tarversing
408 the table. Added function silc_hash_table_list_reset that must
409 be called after the tarversing is over. The affected files are
410 lib/silcutil/silchashtable.[ch].
412 * Changed all hash table traversing to call the new
413 silc_hash_table_list_reset in server and in client library.

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

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

561 of the server and not the servername for the filename.
562 The hostname public key filename is checked as an fall back
563 method if the IP address based filename is not found.
565 Fixed the GETKEY command to save the fetched server key
568 Print the remote server's hostname now when new key is
569 received during connection process. Affected file is
570 irssi/src/silc/core/client_ops.c.
572 * Return always our own public key to the client if it asks
573 for it with GETKEY command. Affected file silcd/command.c.
575 * Removed the use_auto_addr variable from default config
576 file since it was in wrong section. Affected file is
579 * Fixed TOPIC_CHANGE notification to not route it when it
580 was sent using silc_server_send_notify_to_channel function.
581 Affected file silcd/command.c.
583 * Fixed silc_server_send_notify_kicked to send the kicker's
584 Client ID also, it was missing. Affected files are
585 silcd/command.c, silcd/packet_send.[ch].
587 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
589 * Do not save client history information in SERVER_SIGNOFF.
590 Fixes the bug in normal server that it does not detect
591 the client becoming valid after the server becomes back
592 online. Affected file silcd/server_util.c.
594 * Added `sock_error' field into the SilcSocketConnection
595 context. When error occurs during socket operation (read
596 or write) the error is saved. Added also new function
597 silc_socket_get_error to return human readable socket error
598 message. Affected files are lib/silcutil/silcsockconn.[ch],
599 lib/silcutil/unix/silcunixsockconn.c, and
600 lib/silcutil/win32/silcwin32sockconn.c.
602 * The server now prints the socket error message in the
603 signoff for client. Affected file silcd/server.c.
605 * Fixed the `created' channel information sending from router
606 to server in JOIN command. Checks now whether the channel
607 really was created or not and set it according that.
609 Fixed the JOIN command to use the client entry's current
610 ID during the joining procedure instead of the one it sent
611 in the command (it is checked though), since it can change
612 between the packet processing and command processing, and
613 would just case unnecessary pain in the client end. Affected
614 file silcd/command.c.
616 * Fixed a channel key payload sending to use correct channel
617 ID when the server was forced to change the channel's ID by
618 router. Router sent the key payload with the old Channel ID.
619 Affected file silcd/packet_receive.c.
621 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
623 * Call silc_server_save_channel_key only if the key payload
624 was provided in the JOIN command's command reply. Affected
625 file silcd/command_reply.c.
627 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
629 * Fixed silc_mp_sizeinbase to return the value correctly with
630 MPI. Affected file lib/silcmath/mp_mpi.c.
632 * Fixed the stop_server signal to correctly stop the scheduler
633 and gracefully stop the server when SIGTERM or SIGINT signals
634 are received. Affected file silcd/silcd.c.
636 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
638 * Simple handling of TERM and HUP signals. Also added some log
639 flushing call around. Affected file is
642 * Fixed small bugs in silclog.c. Now buffering output will take
643 effect after 10 seconds since startup: This will ensure that
644 no important startup messages are lost. Also output redirection
645 will preserve original format ([Date] [Type] message).
646 Affected file is lib/silcutil/silclog.c.
648 * Added two options to the config file, in the logging section:
649 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
650 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
652 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Do not print the warning about log files not being initialized
655 more than once to avoid excess logging. Affected file is
656 lib/silcutil/silclog.c.
658 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
659 the SIM copying in make install in Makefile.am.pre.
661 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
663 * Rewritten silclog APIs. Globally interesting changes follows:
664 silc_log_set_files() changed to silc_log_set_file().
665 silc_log_set_callbacks() changed to silc_log_set_callback().
666 ROBOdoc documented silclog header file.
667 SilcLogCb now returns bool to wether inihibit the default
668 handler or not (to keep the old behaviour return always TRUE).
669 The new APIs should also fix the problem of the
670 silcd_error.log file that was written in the current directory.
673 Log files streams will remain opened after silc_log_set_file()
674 call, means less CPU usage notably on high traffic servers.
675 File streams are now full buffered, and flushed to the disk
676 every 5 minutes, lesses HD activity and CPU usage.
677 Messages can be redirected, allowing admins to configure
678 one single logfile for all server messages.
679 the silc_log_quick global variable to activate fast-logging.
680 Affected files lib/silcutil/silclog.[ch]
682 * Changed some code to conform new silclog APIs. Affected
683 files are doc/example_silcd.conf.in, silcd/server.c
684 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
687 * Fixed a memory leak that could occur in some situations.
688 Affected file silcd/serverconfig.c.
690 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
692 * Added the silc_client_del_client to remove the client from
693 all channels as well. Affected file lib/silcclient/idlist.c.
695 * Fixed the client library to correctly remove the client
696 from all channels when the client entry is being destroyed.
697 Affected file lib/silcclient/client_notify.c, command.c.
699 * Added auto-nicking support to the client library. If the
700 applicatio now sets client->nickname it will be sent to the
701 server after connecting by the library. This way for example
702 SILCNICK (or IRCNICK) environment variables will have effect
703 and always change the nickname automatically to whatever
704 it is wanted. Affected file lib/silcclient/client.[ch].
706 * Renamed silc_server_command_bad_chars to the
707 silc_server_name_bad_chars and moved it to the
708 silcd/server_util.[ch]. Added also new function
709 silc_server_name_modify_bad to return nickname that
710 includes bad characters as new nickname without those
711 bad characters. This check and modify is now used in
712 silc_server_new_client when the username is initially set
713 as nickname, so it must be checked to be valid nickname.
714 Affected file silcd/packet_receive.c.
716 * The nickname length is now taken from the packet for real
717 and not trusted to strlen() since it clearly can return
718 wrong length for nickname including bad characters. This
719 also applies to channel names. Affected file silcd/command.c.
721 * Removed the lib/silcsilm/modules directory. Modules are now
722 compiled into the lib/silcsim. Fixed the copying of the
723 modules to follow symbolic links in Makefile.am.pre.
725 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
727 * Fixed silc_string_regexify list creation. Fixes bugs with
728 BAN and INVITE commands in server. The affected file is
729 lib/silcutil/unix/silcunixutil.c.
731 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
733 * Removed the command destructor entirely from the server's
734 command and command reply routines. It is not needed, and
735 its usage was buggy and caused crashes. Affected files are
736 silcd/command[_reply].[ch].
738 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
740 * Cancel protocol and NULL sock->protocol if timeout
741 occurred during protocol. Affected file silcd/server.c.
743 * Cancel protocol timeouts always before calling the final
744 callback, to assure that after final callback is called
745 no other state will be called for the protocol anymore.
746 Affected file silcd/protocol.c.
748 * Print error log if incoming connection configuration could
749 not be found. Affected file silcd/server.c.
751 * Fixed JOIN command to correctly save the founder mode
752 to the client on normal SILC server, when the channel
753 was created by the router. Affected file silcd/command.c.
755 * Fixed LIST command (hopefully) to send correct reply
756 packets. Affected file silcd/command.c.
758 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
760 * The silc_packet_receive_process now returns FALSE if the
761 read data was invalid packet, and TRUE if it was ok.
763 The server now checks that if unauthenticated connection
764 sends data and its processing fails the server will close
765 the connection since it could be a malicious flooder.
767 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
769 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Make sure the warning about error opening a log file is
772 printed only once and not everytime it fails (produces
773 too much useless log). Affected file lib/silcutil/silclog.c.
775 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
777 * Made the silc_server_daemonise() function more readable.
778 Affected file silcd/server.c.
780 * Pid file is now optional, the user may comment it out from
781 the config file. Removed define SILC_SERVER_PID_FILE, we
782 don't need a default any longer. Affected file
783 configure.in.pre, lib/Makefile.am.pre.
785 * Make some use of the pid file. The server now dies at startup
786 if it detects a valid pid file on his path. The server would
787 die anyway in this circumstance, because of the bind() failure.
788 Affected file silcd/silcd.c.
790 * No longer compiling lib/dotconf.
792 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Fixed JOIN command parsing not to crash. Affected file
795 lib/silcclient/command.c.
797 * Fied the NICK_CHANGE notify to add the new client entry
798 even it is resolved. This removes an <[unknown]> nick
799 thingy bug in the client. Affected file is
800 lib/silcclient/client_notify.c.
802 * Do not try to allocate 0 bytes (efence does not like it)
803 in lib/silccore/silccomand.c when encoding payload.
805 * Do not take IRCNICK as nickname in Irssi SILC client since
806 it is not possible to set nickname before hand connecting
807 the server (TODO has an entry about adding auto-nicking
810 * Changed the silc_server_command_pending to check whether
811 there already exists an pending entry with the specified
812 command, command identifier and pending callback. This is
813 to fix IDENTIFY and WHOIS related crashes that may register
814 multiple pending commands with same identifier. Affected
815 file silcd/command.c.
817 * Fixed the server to reconnect to the router even if it
818 was already reconnecting and EOF was received. This to
819 fix a possibility that the server wouldn't ever try to
820 auto-reconnect to the router. Affected file silcd/server.c.
822 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Fixed the server's password authentication to use the
825 length of the locally saved password, and not the one
826 sent in the packet. Affected file silcd/protocol.c.
828 * Fixed same password authentication problem in the
829 Authentication Payload handling routines in
830 lib/silccore/silcauth.c.
832 * Yet another password authentication problem fixed with
833 channel password handling in silcd/command.c.
835 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
837 * If first character of string in silc_parse_userfqdn is '@'
838 then do not parse it. Affected file is
839 lib/silcutil/silcutil.c.
841 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Fixed minor bug in IDENTIFY command reply sending, which
844 caused various weird problems during JOIN when it was
845 resolving names for users. Affected file silcd/command.c.
847 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
849 * Fixed the IDENTIFY command reply sending to chech better valid
850 clients. It was possible to send incomplete list of replies.
851 Affected file silcd/command.c.
853 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
855 * Added silc_client_command[s]_[un]register functions now to
856 dynamically register the commands in client library. Removed
857 the static table of commands. This allows the client library
858 to call commands without causing the application to know about
859 what commands library has called.
861 Removed the INFO command reply kludge to detect when the command
862 was called by library. Now library use its own command reply
863 function for INFO command.
865 Added function silc_client_command_call to call a command.
866 Application can use it to call command, not access the structure
869 Now all commands that are sent by the client library (not
870 explicitly sent by application) use own command reply functions.
872 Affected files around lib/silcclient/ and in
873 irssi/src/silc/core/.
875 * Fixed the WHOIS command reply sending to chech better valid
876 clients. It was possible to send incomplete list of replies.
878 Fixed the WHOIS and IDENTIFY to send the request to router
879 if normal server did not do it and did not find any results.
881 Affected file silcd/command.c.
883 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Moved the internal data from SilcClient context into its
886 own file, not accesible to application. Affected files
887 lib/silcclient/client.h and lib/silcclient/client_internal.h,
888 and other files in client library.
890 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Added doc/examples installation target in Makefile.am.pre.
895 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
897 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
898 commands the found client entry will be removed from the
899 cache, after notifying application about the error. Affected
900 file lib/silcclient/command_reply.c.
902 * Changed the /MSG to check for exact nickname user gave, and
903 not let `nick' match `nick@host' if it is only one found. Now,
904 user must type the exact nickname (like nick@host2) even if
905 there are no more than one same nicks found. This is to avoid
906 a possibility of sending nickname to wrong nickname since
907 `nick' could match `nick@host'. Affected file is
908 irssi/src/core/silc-servers.c.
910 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Do not print "you are now server operator" or similar when
913 giving /away command. Affected files are
914 irssi/src/silc/core/client_ops.c, silc-servers.h.
916 * Made the silc_server_command_pending_error_check to send
917 the same command reply payload it received back to the
918 original sender of the command. This way all arguments
919 that was received by the server will be received by the
920 client too. Affected file silcd/command.c.
922 * Added the silc_idcache_add to return the created cache entry
923 to a pointer. Affected file lib/silccore/silcidcache.[ch].
925 * Add global clients to expire if they are not on any channel.
926 This is because normal server will never know if they signoff
927 if they are not on any channel. The cache expiry will take
928 case of these entries. This is done by normal servers only.
929 The affected files are silcd/command_reply.c,
930 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
932 * If server receives invalid ID notification for WHOIS or
933 IDENTIFY and the ID exists in the lists, it is removed.
934 Affected file silcd/command_reply.c.
936 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
937 in client then client entry that it matches is searched and
938 the nickname is printed on the screen for user. Affected
939 file irssi/src/silc/core/client_ops.c.
941 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
943 * Use cache entry expire time in the LIST command reply to
944 purge old entries from the cache after the LIST command
945 reply has been received. This way we don't have non-existent
946 entries in the cache for too long. Affected file is
947 silcd/command_reply.c.
949 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
951 * If we are normal server, and we've not resolved client info
952 in WHOIS or IDENTIFY from router, and it is global client,
953 we'll check whether it is on some channel. If it is not
954 then we cannot be sure about its validity and will resolve it
955 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
956 file silcd/command.c.
958 * Search channel by name (if possible) rather than by ID
959 in IDENTIFY command's command reply. Affected file is
960 silcd/command_reply.c.
962 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Distribute to the channel passphrase in CMODE_CHANGE notify.
965 Updated specs and implemented it. Affected file silcd/command.c,
966 silcd/packet_send.c and silcd/packet_receive.c.
968 * Implemented the <founder auth> payload handling in the JOIN
969 command. If provided all conditions for channel joining
970 except requirement to provide correct passphrase can be
971 overrided by the channel founder. Updated the protocol specs.
972 Affected file silcd/command.c.
974 Added support for founder auth in JOIN command in client
975 library. Fixed the parsing of the JOIN command now to support
976 all options as they should be. The affected file is
977 lib/silcclient/command.c.
979 * Optimized the WHOIS and IDENTIFY commands to send the request
980 to router only if it includes nicknames or other names. If
981 they include only IDs then check the local cache first before
982 routing. Affected file is silcd/command.c.
984 * Added channels topic announcements. Affected file is
985 silcd/packet_receive.c and silcd/server.c.
987 * Fixed the silc_server_send_notify_topic_set to really destine
988 the packet to channel. Affected file silcd/packet_send.c.
990 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
991 library. Affected file lib/silcclient/client_notify.c.
993 * Added UMODE announcements. Affected file silcd/server.c.
995 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
997 * Memory leak fixes in:
999 lib/silcutil/silcsockconn.c
1000 lib/silcske/silcske.c
1001 lib/silcske/groups.c
1003 lib/silccrypt/silcpkcs.c
1004 lib/silccore/silccommand.c
1005 lib/silccore/silcidcache.c
1010 * ROBOdoc documented the lib/silcske/groups.h file and a
1011 bit changed the interface for better.
1013 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1015 * Update the client entry context in the ID cache after
1016 nick change. Affected file lib/silcclient/command.c.
1017 Fixes the CUMODE command when regaining founder privileges,
1018 and a little WHOIS problem.
1020 * Fixed silc_net_gethostbyname to correctly call the
1021 inet_ntop. Affected file lib/silcutil/silcnet.c.
1023 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1025 * Added IPv6 support checking to the configure.in.pre, added
1026 also --enable-ipv6 option to override the check. Affected
1027 file configure.in.pre.
1029 * The silc_thread_create now calls the start function
1030 directly if threads support is not compiled in. Removes
1031 ugly #ifdef's from generic code. Affected files are
1032 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1034 * Added silc_net_gethostby[name/addr]_async to asynchronously
1035 resolve. Affected files are lib/silcutil/silcnet.[ch].
1037 * Added support for rendering IPv6 based server, client and
1038 channel IDs. Affected file lib/silcutil/silcutil.c.
1040 * Added support for creating IPv6 based server IDs. Affected
1041 file is silcd/serverid.c.
1043 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1045 * Added silc_net_gethostby[addr/name] into the
1046 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1047 routines. Added silc_net_is_ip[4/6]. Affected file is
1048 lib/silcutil/unix/silcunixnet.c. All routines that take
1049 address as argument now supports both IPv4 and IPv6 addresses.
1051 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1053 * Fixed LIST command reply sending in server. Affected file
1056 * Server now sends the kicker's client ID in the KICK notify
1057 to the kicked client. Affected file silcd/command.c.
1059 * The client library now parses the kickers client ID and
1060 UI displays it. Affected files lib/silcclient/client_notify.c
1061 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1063 * Made all payload parsing function prototypes consistent.
1064 They all take now const unsigned char * and uint32 pair as
1065 the payload data instead of SilcBuffer. Changes all around
1066 the source tree. Other unsigned char* -> const unsigned char*
1067 changes around the tree as well.
1069 * Optimized SFTP client and server packet sending not to
1070 allocate new buffer for each packet but to recycle the
1071 first allocated buffer. Affected files are
1072 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1074 * Optimized the SFTP client to use SilcList instead of
1075 SilcDList for requests, because it is faster. Affected file
1076 is lib/silcsftp/sftp_client.c.
1078 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1079 into lib/silccore/silcid.[ch].
1081 Renamed silcpayload.[ch] into silcargument.[ch].
1083 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * If client entry is deleted with active key agreement
1086 session, abort the session.
1088 The silc_client_abort_key_agreement now calls the completion
1089 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1091 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1094 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Don't use __restrict in older GCC's. Affected file is
1097 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1099 * silc_net_localhost now attempts to reverse lookup the
1100 IP/hostname. Affected file lib/silcutil/silcnet.c.
1102 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1103 command. It can be used to gain founder privileges at
1104 the same time when joining the channel.
1106 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1107 kicker's client ID as well. Updated protocol specs.
1109 Defined that the server must send SILC_COMMAND_IDENTIFY
1110 command reply with error status to client who sent
1111 private message with invalid client ID.
1113 Updated the protocol specification.
1115 * Added silc_server_send_command_reply to send any
1116 command reply. Affected file silcd/packet_send.[ch].
1118 * Added silc_id_payload_encode_data to encode ID payload
1119 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1121 * The server now send IDENTIFY command reply with error
1122 status if client ID in private message is invalid. Affected
1123 file silcd/packet_receive.c.
1125 * Save the server key file with server's IP address in
1126 the filename instead of hostname. The affected file is
1127 irssi/src/silc/core/client_ops.c.
1129 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1134 * Added libtool support for compiling shared objects in
1135 lib/silcsim. Affected file configure.in.pre and
1136 lib/silcsim/Makefile.am. Original patch by cras.
1138 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Pid file configuration, and server's config file fixes
1141 patch by toma. Updated CREDITS file.
1143 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1145 * Fixed silc_client_channel_message to not try to decrypt
1146 the message twice if it resolved the destination client
1147 information. This could cause of dropping one channel
1148 message. Affected file lib/silcclient/client_channel.c.
1150 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1153 lib/silcclient/client.c. This function is used when the SILC
1154 Client is run under some other scheduler, or event loop or
1155 main loop. On GUI applications, for example this may be
1156 desired to used to run the client under the GUI application's
1157 main loop. Typically the GUI application would register an
1158 idle task that calls this function multiple times in a second
1159 to quickly process the SILC specific data.
1161 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1163 * Fixed silc_server_drop() for dropping the supplementary
1164 groups as well, this could cause a security hole on some
1167 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1172 * Write PID file after dropping privileges. Added -F option
1173 to run server on foreground. A patch by debolaz.
1174 Affected files silcd/server.c, silcd/silcd.c.
1176 * Fixed MOTD to return the MOTD file server name. Affected
1177 file silcd/command.c.
1179 * Added INFO command reply handling to the Irssi SILC Client.
1180 Affected file irssi/src/silc/core/client_ops.c.
1182 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1184 * Fixed the silc_idcache_list_* routines to really support
1185 the dynamic list. Fixes a crash. Affected file is
1186 lib/silccore/silcidcache.c.
1188 * Fixed the LIST command reply to really call LIST command's
1189 pending callbacks. Affected file silcd/command_reply.c.
1191 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Update conn->local_entry->nickname after giving NICK
1194 command. Affected file lib/silcclient/command.c.
1196 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1198 * Added the [pid] option to the silcd configuration file
1200 Affected files: serverconfig.[ch] and silcd.c
1202 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Save fingerprint in WHOIS command reply in server.
1205 Affected file silcd/command_reply.c.
1207 * Fixed NICK commands pending callback registration.
1208 Affected file lib/silcclient/command.c.
1210 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Use ++server->cmd_ident when sending commands in server,
1213 instead of random number. Affected file silcd/command.c.
1215 * Fixed GETKEY command reply to call actually GETKEY pending
1216 command callbacks. Affected file silcd/command_reply.c.
1218 * A bit stricter check for nicknames. Check for same nickname
1219 in NICK command also. Affected file silcd/command.c.
1221 * Do not call INFO command everytime client ID changes, only
1222 during first connecting. Affected file lib/silcclient/client.c.
1224 * Set the new nickname only after successful command reply for
1225 NICK command is returned by server. Affected file
1226 lib/silcclient/command.c.
1228 * Remove nicknames from nicklist during server_signoff notify.
1229 Should fix /NAMES bit more. The affected file is
1230 irssi/src/silc/core/silc-channels.c.
1232 * Added `fingerprint' field to the SilcIDListData in the
1233 silcd/idlist.h to hold the fingerprint of the client's
1236 Send the fingerprint of the client's public key in WHOIS
1239 Affected files silcd/command.c, and silcd/idlist.[ch].
1241 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1242 create fingerprint from given data.
1244 * Show the fingerprint of the client's public key in WHOIS.
1245 Affected files irssi/src/module-formats.[ch] and
1246 irssi/src/silc/core/client_ops.c.
1248 * Format the multiple same nicknames also during JOIN and
1249 NICK_CHANGE notifys. Affected file is
1250 lib/silcclient/client_notify.c.
1252 * Do not print error on screen for invalid private message
1253 payload since it can come if someone is sending private
1254 messages with wrong key. Affected file
1255 lib/silccore/silcprivate.c.
1257 * Fixed multiple concurrent /PING crash. Affected file
1258 lib/silcclient/command.c.
1260 * Changed the wrong ID encoding. All IP addresses must be
1261 in MSB first order in encoded format. They were encoded
1262 wrong and was in LSB format. Affected files are
1263 silcd/serverid.c, lib/silcutil/silcutil.c.
1265 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1267 * Call the `connect' client operation through the scheduler
1268 in case of error. Affected file lib/silcclient/client.c.
1270 * Call the `failure' client operation even if the error
1271 occurred locally during a protocol. Affected file is
1272 lib/silcclient/protocol.c.
1274 * Added support of sending LIST command to router from normal
1275 server. This way normal server can get list of all channels
1276 in the network too. Fixed the channel list sending in the
1277 server too. Affected files are silcd/command.c, and
1278 silcd/command_reply.[ch].
1280 * Added silc_server_update_channels_by_server and
1281 silc_server_remove_channels_by_server. They are used during
1282 disconnection of primary router and in backup router protocol.
1283 Affected file silcd/server_util.[ch], silcd/server.c and
1284 silcd/server_backup.c.
1286 * Fixed channel adding to global list in IDENTIFY command
1287 reply in server. Affected file silcd/command_reply.c.
1289 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * If the incoming packet type is REKEY or REKEY_DONE process
1292 that packet always synchronously. Fixes yet another MAC
1293 failed error on slow (dialup) connections. Affected file
1294 lib/silcclient/client.c and silcd/server.c.
1296 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Call check_version SKE callback for initiator too. Affected
1299 file lib/silcske/silcske.c.
1301 * Implemented fix for security hole found in the SKE that was
1302 fixed in the specification few days back; the initiator's
1303 public key is now added to the HASH value computation.
1304 Added backwards support for the old way of doing it too, for
1305 old clients and old servers. Affected file is
1306 lib/silcske/silcske.c.
1308 * Enabled mutual authentication by default in SKE. If initiator
1309 is not providing mutual authentication the responder will
1310 force it. This will provide the proof of posession of the
1311 private key for responder. The affected files are
1312 lib/silcclient/protocol.c and silcd/protocol.c.
1314 * Do not cache anymore the server's public key during SKE.
1315 We do mutual authentication so the proof of posession of
1316 private key is done, and if the server is authenticated in
1317 conn auth protocol with public key we must have the public
1318 key already. Affected file silcd/protocol.c.
1320 * Added new global debug variable: silc_debug_hexdump. If
1321 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1322 file lib/silcutil/silclog.[ch].
1324 * Fixed compilation warning due to char * -> const char *.
1325 Affected files lib/silcutil/silcnet.h, and
1326 lib/silccore/silcauth.[ch].
1328 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * Fixed CMODE command when new channel key was created. If
1331 the creation failed the old key was removed. Next time giving
1332 same command would crash the server since the old key was
1333 freed already. Affected file silcd/command.c.
1335 * Fixed the silc_server_announce_get_channels to not crash
1336 on reconnect. Affected file silcd/server.c.
1338 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Added silc_log_set_debug_string function to set a regex
1341 string to match for debug output. Only the function names,
1342 or filenames matching the given debug string is actually
1343 printed. This way it is possible to filter out those debug
1344 strings that user is not interested in.
1346 Fixed a bug in silc_string_regexify.
1348 Affected files lib/silcutil/silclog.[ch], and
1349 lib/silcutil/unix/silcunixutil.c.
1351 * Changed the -d options in both server and Irssi SILC client
1352 to take the debug string as argument. Affected files
1353 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1355 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1357 * Added silc_hash_babbleprint to create a Bubble Babble
1358 Encoded fingerprint. The encoding is developed by Antti
1359 Huima (draft-huima-babble-01.txt), and it creates human
1360 readable strings out of binary data. Affected file
1361 lib/silccrypt/silchash.[ch].
1363 * Print the babble print now in addition of fingerprint as well
1364 in Irssi SILC client. Affected files are
1365 irssi/src/fe-common/silc/module-formats.[ch],
1366 irssi/src/fe-common/silc/core/client_ops.c.
1368 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Fixed a security problem found in SKE. The initiator's
1371 public key too is now added to the HASH hash value creation
1372 which is signed by the responder to create the SIGN value.
1373 This will prevent anyone in the middle to lie to the responder
1374 about the initiator's public key. If this is done now, the
1375 man in the middle will get caught. Updated the protocol
1378 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Better installation directory handling. Configure module
1381 paths and other paths automatically to example_silc* files
1382 in doc/. A patch by toma.
1384 * Fixed compiler warning from MPI library, and from SILC RNG.
1387 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1388 It can be configured with ./configure. A patch by toma.
1390 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Find correct make to use in prepare-clean. A patch by
1393 toma. Affected file prepare-clean.
1395 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1397 * Added irssi variables use_auto_addr, auto_bind_ip,
1398 auto_bind_port and auto_public_ip.
1400 * Changed the interface for silc_client_send_key_agreement
1401 in lib/silcclient/silcapi.h
1405 irssi/src/silc/core/silc-core.c
1407 lib/silcclient/silcapi.h
1408 irssi/src/silc/core/silc-channels.c
1409 lib/silcclient/client_keyagr.c
1412 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * Added silc_pkcs_public_key_compare to compare two
1415 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1417 * Check that the client who set the founder mode on the
1418 channel is the same client that is giving the founder
1419 mode to itself. It is done by comparing the saved public
1420 key (it is saved even in the authentication is passphrase).
1421 Affected file silcd/command.c.
1423 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Do not process packet for disconnected socket connection.
1426 Affected file lib/silccore/silcpacket.c.
1428 * Process the DISCONNECT packet through scheduler in the
1429 client library. Affected file lib/silcclient/client.c.
1431 * Fixed the silc_client_packet_parse to not to increase
1432 the packet sequence number if the conn->sock and the
1433 current socket connection is not same. This can happen
1434 for example during key agreement when the conn includes
1435 multiple socket connections (listeners). Affected file
1436 lib/silcclient/client.c.
1438 * The sender of the file transfer request now provides also
1439 the pointer (listener) for the key exchange protocol. If
1440 the listener cannot be created then it sends empty key
1441 agreement and lets the receiver provide the listener.
1443 Added `local_ip' and `local_port' arguments to the
1444 silc_client_file_send. If they are provided they are used,
1445 if not then it will attempt to find local IP address, if
1446 not found or bind fails then the remote client will provide
1449 Affected files are lib/silcclient/client_ftp.c and
1450 lib/silcclient/silcapi.h.
1452 * Extended the FILE SEND command to support defining the
1453 local IP and port for key exchange listener. They are
1454 optional. Affected file irssi/src/silc/core/silc-servers.c.
1456 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Defined to WHOIS command reply the sending of fingerprint
1459 of the client's public key (if the proof of posession of the
1460 corresponding private key is verified by the server).
1461 Updated to the protocol specification.
1463 * Added support of receiving the client's public key's
1464 fingerprint in command reply in client library. Affected
1465 file is lib/silcclient/command_reply.c, and
1466 lib/silcclient/idlist.[ch].
1468 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Do not send over 128 chars long nickname to the server
1471 in NICK command. Affected file lib/silcclient/command.c.
1473 * Do not send over 256 chars long channel names to the server
1474 in JOIN command. Affected file lib/silcclient/command.c.
1476 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Assure that silc_server_close_connection cannot be called
1479 twice for same socket context. Affected file is
1482 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Send error message to application if opening file for
1485 writing during file transfer fails. Affected file is
1486 lib/silcclient/client_ftp.c.
1488 Remove all file transfer sessions for a client that we're
1489 removing from ID cache.
1491 Affected file is lib/silcclient/client_ftp.c.
1493 * Fixed silc_net_addr2bin to return correct address. Affected
1494 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1496 * Fixed file transfer session removing on signoff notify.
1497 Affected file irssi/src/silc/core/silc-servers.c.
1499 * Added the SilcClientFileError to be returned in the monitor
1500 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1501 Affected file lib/silcclient/silcapi.h.
1503 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Fixed a crash in silc_client_ftp_free_sessions and
1506 silc_client_ftp_session_free_client. Affected file
1507 lib/silcclient/client_ftp.c.
1509 * Added `disabled' field in the SilcChannelEntry in the server
1510 to indicate if the server entry is disabled. Affected file
1511 silcd/idlist.h, silcd/command[_reply].c.
1513 * SILC server adds now /var/run/silcd.pid everytime it is
1514 started. Affected file silcd/silcd.c.
1516 * Added silc_server_packet_send_clients to send a packet to
1517 the provided table of client entries. Affected file
1518 silcd/packet_send.[ch].
1520 * Fixed a crash in client resolving in client_prvmsg.c in
1521 client library. Affected file lib/silcclient/client_prvmsg.c.
1523 * Do not actually remove the client directly from ID cache
1524 during SERVER_SIGNOFF, but invalidate it. This way we
1525 preserve the WHOWAS info for the client. Affected file
1526 silcd/server_util.c.
1528 * Fixed SERVER_SIGNOFF notify handling in the server. The
1529 server is now able to process incoming SERVER_SIGNOFF notify
1530 for a server that it doesn't even know about. It will remove
1531 the clients provided in the notify. Affected file
1532 silcd/packet_receive.c.
1534 * Check for partial packet in data queue after every packet that
1535 was found from the queue. Return and wait for more data if
1536 there is partial data in queue. Affected file is
1537 lib/silccore/silcpacket.c.
1539 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Added SilcClietFileError enum to indicate error in
1542 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1543 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1544 Affected files lib/silcclient/silcapi.h and
1545 lib/silcclient/client_ftp.c.
1547 * Check that newsize in silc_buffer_realloc is larger than
1548 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1550 * Added better monitor of file transfers. It now monitors
1551 key agreement protocol during the file transfer too. Added
1552 error reporting too. Affected files
1553 irssi/src/silc/core/silc-servers.c,
1554 irssi/src/fe-common/silc/module-formats.[ch].
1556 * Wrote a help file for FILE command.
1558 * Added silc_rng_global_get_byte_fast to get not-so-secure
1559 random data as fast as possible. Random data is read from
1560 /dev/urandom if available and from the SILC RNG if not
1561 available. It is used in padding generation. Affected file
1562 lib/silccrypt/silcrng.[ch].
1564 * All packets in client library are now processed synchronously.
1565 Optimized packet processing a lot. Affected file
1566 lib/silcclient/client.c.
1568 * All server connection packets are processing synchronously
1569 now in server, to optimize packet processing. Affected file
1572 * Include files are installed now only in Toolkit distribution
1573 if make install is given. Affected files: all Makefile.am's.
1575 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Assure that silc_client_notify_by_server_resolve does not
1578 resolve the client information multiple times. If it cannot
1579 be found by the first it cannot be found at all. Affected
1580 file lib/silcclient/client_notify.c.
1582 * Fixed WHOWAS command reply calling. Affected file
1583 lib/silcclient/command_reply.c.
1585 * Removed all references to silc_idlist_get_client from the
1586 Irssi SILC client since that call is internal call used by
1587 the library. The Irssi SILC client will use now client
1588 retrieval functions found in silcapi.h.
1590 * Fixed a bug in resolving nickname info before sending
1591 private message. It used freed memory. Affected file
1592 irssi/src/silc/core/silc-servers.c.
1594 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Assure my_channels statistics cannot go negative in server.
1597 Affected files silcd/server.c, silcd/server_util.c.
1599 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1603 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * Win32 Toolkit changes. Affected files
1606 win32/silc.dsw, win32/libsilc/libsilc.def,
1607 win32/libsilcclient/libsilc.def,
1608 lib/silcutil/silcutil.c, and
1609 lib/sftp/sftp_fs_memory.c.
1611 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Added silc_net_localip to return local host's IP address.
1614 Affected file lib/silcutil/silcnet.[ch].
1616 * If key exchange or rekey protocol is active for a connection
1617 parse all packets syncronously since there might be packets
1618 in packet queue that we are not able to process without first
1619 processing packets before them. Affected file silcd/server,
1620 lib/silcclient/client.c.
1622 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1623 whether library should continue processing the packet.
1624 Affected file lib/silccore/silcpacket.h.
1626 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1627 SilcSFTPMonitorData to SFTP server to monitor various
1628 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1629 lib/silcsftp/sftp_server.c.
1631 * Added silc_file_size to return file size. Affected file
1632 lib/silcutil/silcutil.[ch].
1634 * Implemented the file transfer support for the client library.
1635 Added preliminary support for simple client to client one-file
1636 transmission. Affected file lib/silcclient/client_ftp.c,
1637 lib/silccilent/client.[ch].
1639 * Added new local command FILE to the Irssi SILC Client.
1640 It is used to perform the file transfer. It has subcommands
1641 SEND, RECEIVE, SHOW and CLOSE. Affected files
1642 irssi/src/silc/core/client_ops.c,
1643 irssi/src/silc/core/silc-server.[ch].

1650 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1652 * Renamed silc_file_read and silc_file_write to functions
1653 silc_file_readfile and silc_file_writefile. Added function
1654 silc_file_open and silc_file_close. Affected files
1655 lib/silcutil/silcutil.[ch].
1657 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Resolve the client info when received private message or
1660 channel message for a client which nickname we don't know.
1661 Affected files lib/silcclient/client_prvmsg.c and
1662 lib/silcclient/client_channel.c.
1664 * Do not crash in /KEY if client is not connected. Affected
1665 file irssi/src/silc/core/silc-channels.c.
1667 * Added SilcClientStatus field to the SilcClientEntry in the
1668 lib/silcclient/idlist.h.
1670 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1671 is incomplete and is being resolved, it won't be resolved
1674 Make sure also that USERS command reply does not resolve
1675 twice information. Affected file is
1676 lib/silcclient/command_reply.c.
1678 Make sure that silc_client_get_clients_by_list does not
1679 resolve twice same information.
1681 * Check for valid client->id in the silc_server_free_client_data.
1682 Affected file silcd/server.c.
1684 * Fixed /GETKEY nick@server not to crash if the server entry
1685 is not found. Affected file lib/silcclient/command.c.
1687 * Fixed the silc_server_check_cmode_rights to check the
1688 requested modes correctly. Affected file silcd/command.c.
1690 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Better checks for non-printable chars in nick added.
1693 Affected file silcd/command.c.
1695 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Call the silc_server_udpate_servers_by_server in the
1698 primary router that comes back online in the backup resuming
1699 protocol. Otherwise it routes packets wrong. Affected file
1700 silcd/server_util.[ch], silcd/server_backup.c.
1702 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1705 lib/silcutil/silcbuffmt.[ch].
1707 * Redefined the SILC packet header to include the padding
1708 length. Affected file lib/silccore/silcpacket.[ch].
1710 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1711 length for maximum padding up to 128 bytes). Affected
1712 file lib/silccore/silcpacket.h.
1714 * Removed all backwards support for old 0.5.x MAC thingies.
1715 The SILC packet header change makes it impossible to be
1716 backwards compatible.
1718 * Send the ENDING packet with timeout in the backup resuming
1719 protocol. This is to assure that all routers has connected
1720 to the primary router. Affected file silcd/server_backup.c.
1722 * Changed the RNG to take the first IV from random data. It
1723 used to take it from zero actually. Changed the RNG also
1724 to use /dev/urandom during session. /dev/random is used
1725 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1727 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Changed the SILC packet header to have the first two bytes
1730 (the packet length) encrypted. Affected files aroung the
1731 code tree, lib/silccore/silcpacket.[ch]. Removed the
1732 SilcPacketCheckDecrypt callback. It is not needed anymore
1733 since the silc_packet_receive_process will determine now
1734 whether the packet is normal or special.
1736 * Implemented the unidirectional MAC keys. Affected files
1737 lib/silcske/silcske.c, silcd/protocol.c and
1738 lib/silcclient/protocol.c.
1740 * Implemented the packet sequence number to the MAC computation.
1741 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1742 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1743 lib/silcclient/protocol.c.
1745 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Allow backup router to announce servers. All servers
1748 announced by backup router are added to the global list
1749 automatically. Update hte server's socket to our primary
1750 router also when backup router announces a server.
1751 Affected file silcd/packet_receive.c.
1753 * Do not update the client->router in the function
1754 silc_server_udpate_clients_by_server if the client is on
1755 global list. We might fail to find any specific server
1756 for locally connected clients and local cell clients. They
1757 should still use the `from' and not `to' as client->router.
1758 This fixes backup router resuming protocol. Affected file
1759 silcd/server_util.c.
1761 * Decrease channel statistics count only if the channel
1762 deletion worked. Affected files are silcd/server.c and
1763 silcd/server_util.c.
1765 * Added silc_server_update_servers_by_server to update origin
1766 of all server entries. Used during backup router protocol.
1767 Affected files silcd/server_util.[ch], silcd/server.c. and
1768 silcd/backup_router.c.
1770 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1771 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1772 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1773 lib/silccrypt/silchmac.c.
1775 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Assure that router cannot reroute the same channel message
1778 to the sender. Affected file silcd/packet_receive.c.
1780 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Made better checks that the channel message is not sent
1783 to the router it came from. Affected file is
1784 silcd/packet_send.c. Fixed memory leak too.
1786 * Announce informations for incoming router connection, but
1787 only after checking if it is replaced by backup router.
1788 Affected file silcd/packet_receive.c.
1790 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Fixed the backup resuming protocol to work in multiple
1793 router environment. Affected file silcd/server_backup.c.
1795 * Route packet only to one router in the function
1796 silc_server_packet_send_to_channel. Affected file is
1797 silcd/packet_send.c.
1799 * Fixed silc_server_send_notify_dest to set the broadcast
1800 flag. Fixed the silc_server_send_notify_topic to actually
1801 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1802 Affected file silcd/packet_send.c.
1804 * Changed the SFTP Filesystem interface. Changed the
1805 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1806 the filesystem operation function. The SilcSFTPFilesystem
1807 is now a context that is allocated by all filesystem allocation
1808 functions and it already includes the operations structure
1809 and filesystem specific context. It is given as argument
1810 now to the silc_sftp_server_start. This made the interface
1811 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1812 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1814 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Changed the backup router adding and getting interfaces
1817 in the server. The router that will be replaced by the
1818 specified backup router is now sent as argument. Affected
1819 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1822 * Added silc_net_addr2bin_ne to return the binary form of
1823 the IP address in network byte order. Affected files
1824 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1826 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * Check for existing server ID in silc_server_new_server
1829 and in silc_server_connect_to_router_final and remove the
1830 old entry if it exists. Affected file silcd/packet_receive.c,
1833 * Send the channel message always to only one router, either
1834 in upstream or downstream. Affected file is
1835 silcd/packet_send.c.
1837 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Wrote the definition of the backup resuming protocol to the
1840 protocol specification.
1842 * Removed one redundant channel key generation from normal
1843 server during joining procedure. Removed one redundant
1844 channel key sending from server to router during joining
1845 procedure. Affected file silcd/command.c.
1847 * Made minor bugfixes to the backup router resuming protocol.
1848 Affected file silcd/server_backup.c, server.c.
1850 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Added --disable-asm configuration option. Affected files
1853 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1856 * Implemented the backup resuming protocol that is used to
1857 resume the primary router position in the cell after the
1858 primary router comes back online. Affected files
1859 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1860 and silcd/server_util.[ch].
1862 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Sleep two (2) seconds after sending QUIT command to server.
1865 Affected file lib/silcclient/command.c.
1867 * Assure that if outgoing data buffer is pending do not force
1868 send any data. Affected file silcd/packet_send.c.
1870 * Assure that if outgoing data buffer is pending do not force
1871 send any data. Affected file lib/silcclient/client.c.
1873 * Implemented the backup router support when the primary router
1874 goes down. The servers and routers can now use the backup
1875 router as new primary router without loosing connectivity.
1877 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1880 in the server to indicate disabled entry. All data read
1881 from the connection will be ignored and no data is sent
1882 for entry that is disabled. Affected files are
1883 silcd/idlist.h, silcd/server.c.
1885 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Created SFTP client and server test programs in the
1888 lib/silcsftp/tests directory.
1890 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Implemented memory filesystem (virtual filesystem) for
1893 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1896 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Implemented the SFTP (SSH File Transfer Protocol) to the
1899 lib/silcsftp. It includes SFTP client and SFTP server
1902 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Moved lib/silccore/silcprotocol.[ch] to the
1905 lib/silcutil library.
1907 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1908 take variable argument list pointer as argument. Affected
1909 file lib/silcutil/silcbuffmt.[ch].
1911 * Added silc_buffer_set function that is used to set data
1912 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1913 Affected file lib/silcutil/silcbuffer.h.
1915 * Changed various routines in the core library to use the new
1916 silc_buffer_set instead of allocating new buffer only for
1919 * Added 64-bit value formatting and unformatting support to the
1920 silc_buffer_[un]format routines. Affected file is
1921 lib/silcutil/silcbuffmt.[ch].
1923 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1924 to includes/bitmove.h.
1926 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Fixed channel user mode saving in client library. Affected
1929 file lib/silcclient/command[_reply].c.
1931 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Defined the file transfer to the SILC Protocol. Added
1934 new packet type SILC_PACKET_FTP and defined File Transfer
1935 Payload. The mandatory file transfer protocol is SFTP
1936 (SSH File Transfer Protocol). Affected file in addition
1937 of the internet draft is lib/silccore/silcpacket.h.
1939 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1940 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1941 is used as part of backup router protocol when the primary
1942 router of the cell is back online and wishes to resume
1943 the position as primary router.
1945 * Redefined the MAC generation keys in the protocol. The
1946 same key is not used anymore in both direction. Both
1947 direction will now use different keys for sending and
1948 receiving. This fixes a potential security flaw. This
1949 change causes incompatibilities in the protocol.
1951 * Redefined also the MAC computation from the packet.
1952 An packet sequence number is now added to the MAC
1953 computation. This prevents possible replay attacks against
1954 the protocol. This change too causes incompatibilities
1957 Added `sequence' field to the SilcPacketContext to hold
1958 the current sequence number for the packet.
1960 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Added `created' field to the SilcIDListData in the file
1963 silcd/idlist.h to indicate the time when the entry was
1966 * Added `created' field to the SilcChannelEntry too. Affected
1967 file silcd/idlist.h.
1969 * Added `creation_time' aguments to all the announcement functions
1970 in the server. If it is provided then only the entries that
1971 was created after the provided time frame are actually
1972 announced. Affected file silcd/server.[ch].
1974 * The protocol says that the Channel ID's IP address must be
1975 based on the router's IP address. Added check for this in
1976 the silc_server_new_channel when processing incoming New Channel
1977 Payload. Affected file silcd/packet_receive.c.
1979 * Print out the correct version with --version in SILC client.
1980 Affected file irssi/src/silc/core/silc-core.c.
1982 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Fixed WHOWAS command to check for completnes of the client
1985 entry always, not just when the command is coming from client.
1986 Affected file silcd/command.c.
1988 * Added new function silc_server_packet_queue_purge to purge the
1989 outgoing data queue to the network. After the function returns
1990 it is guaranteed that the outgoing packet queue is empty.
1991 Affected file silcd/packet_send.[ch].
1993 * Purge the outgoing packet queue in the rekey protocol's final
1994 callback to assure that all rekey packets go to the network
1995 before quitting the protocol. Affected file silcd/server.c.
1997 * Added silc_client_packet_queue_parse as similar function as
1998 in server to the client library. The affected file is
1999 lib/silcclient/client.c.
2001 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Splitted silcd/server.c and created silcd/server_util.[ch]
2004 for utility functions.
2006 * Added new socket flag SILC_SF_DISABLED to indicate that the
2007 connection is open but nothing can be sent to or received from
2008 the connection. Affected file lib/silcutil/silsockconn.[ch].
2009 The checking for disabled socket is checked in the low level
2010 silc_socket_write and silc_socket_read functions.
2012 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Allow only nicknames and channel names that fits into the
2015 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2017 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * When processing JOIN command reply in server check that if
2020 the channel exists in our global list we'll move it the local
2021 list. Affected file silcd/command_reply.c.
2023 * Fixed the check whether client is joined on the channel already
2024 in JOIN command. Affected file lib/silcclient/command.c.
2026 * Fixed the JOIN command reply to check whether the channel
2027 already exists. Affected file lib/silcclient/command_reply.c.
2029 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Added silc_ske_status_string to map the SKE error numbers
2032 to readable strings. The affected files are
2033 lib/silcske/silcske[_status].[ch].
2035 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Do not show the private channels on the WHOIS channel list
2038 as it is not allowed by the protocol. The affected file is
2041 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Assure that the packet length digged from the actual packet
2044 is something sensible in the silc_packet_decrypt_rest_special
2045 in lib/silccrypt/silcpacket.c.
2047 * Free and NULL the allocated pointer in silc_hmac_alloc if
2048 the HMAC allocation fails. The affected file is
2049 lib/silccrypt/silchmac.c.
2051 * Print the selected security properties to the log files in
2052 the server. Affected file silcd/protocol.c.
2054 * Add SKE's reference counter even if calling the completion
2055 callback manually. Otherwise it goes negative, although it
2056 does not cause any problems. The affected file is
2057 lib/silcske/silcske.c.
2059 * Remove the client entry with short timeout after giving the
2060 KILL command. Affected file lib/silcclient/command.c.
2062 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2063 case all found clients are already disconnected (WHOWAS would
2064 found them) in the server. Affected file silcd/command.c.
2066 * Update the last_receive (time of last data received) to be
2067 updated only when received private or channel message so that
2068 the idle time showed in WHOIS makes more sense.
2070 * Added boolean field `valid' in to the SilcClientEntry in the
2071 client library to indicate whether the entry is valid or not.
2072 This fixes the nickname change bug on channel when changing
2073 the nickname to be same than the old (like nick to Nick) the
2074 nickname formatter doesn't set the new nick anymore to Nick@host.
2075 Affected file lib/silcclient/idlist.[ch].
2077 * Now actually fixed the nickname changing on disconnection.
2078 Added new function silc_change_nick to the Irssi SILC Client.
2079 Affected file irssi/src/silc/core/client_ops.c,
2080 irssi/src/silc/core/silc-nicklist.[ch].
2082 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Check that the public key exists in the GETKEY command before
2085 trying to encode it. Affected file silcd/command.c.
2087 * Print some notifications on received public keys with GETKEY
2088 command in the Irssi SILC Client. Affected files are
2089 irssi/src/fe-common/silc/module-formats.[ch],
2090 irssi/src/silc/core/client_ops.c.
2092 * Use IDENTIFY command to resolve the server information in the
2093 GETKEY command instead of INFO command. Affected file
2094 lib/silcclient/command.c.
2096 * All command reply functions in the client library now calls
2097 the pending command reply callbacks even if an error has
2098 occurred. The server has done this a long time and now it was
2099 time to move the client library to this as well. Now all
2100 errors can be delivered back to the pending command reply
2101 callbacks if necessary. Affected files are
2102 lib/silcclient/command[_reply].[ch].
2104 * Change the nickname on disconnection back to the username
2105 because in reconnect the server will enforce it to it anyway.
2106 Affected file irssi/src/silc/core/silc-servers.c.
2108 * Fixed a config file parsing bug in the Irssi SILC client.
2109 Affected file irssi/src/silc/core/clientconfig.c.
2111 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2113 * When printing the channel mode on JOIN, verify that the
2114 channel key and channel's HMAC are valid. Affected file
2115 irssi/src/silc/core/client_ops.c.
2117 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2120 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2121 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2123 * Removed channel key rekey task deleting from the function
2124 silc_server_save_channel_key. Affected file silcd/server.c.
2125 Added explicit timeout task context instead that is used to
2126 delete the task if we are registering a new task before the
2127 new task has elapsed.
2129 * When channel key rekey occurs the client library now saves
2130 the old channel key for a short period of time (10 seconds) and
2131 is able to use it in case some is still sending channel
2132 messages encrypted with the old key after the rekey. Affected
2133 file lib/silcclient/[idlist.h|client_channel.c].
2135 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Added check to the silc_server_new_id_real to not accept
2138 new ID if it is the sender's own ID. Affected file is
2139 silcd/packet_receive.c.
2141 * Assure that we do not announce ourself or the one we've
2142 sending our announcements when we're router and are announcing
2143 servers to our primary router. Affected file silcd/server.c.
2145 * Fixed silc_server_command_identify_check_client to assemble
2146 correct WHOIS packet. It send corrupted WHOIS packet and
2147 caused problem with router to router connections. Affected
2148 file silcd/command.c.
2150 Fixed also silc_server_command_whois_check the same way
2151 as for the IDENTIFY command.
2153 * Added new SilcIDListStatus to the server in the SilcIDListData
2154 structure. The status now includes the current status of
2155 the entry (like registered, resolved etc.). Affected file
2156 silcd/idlist.[ch]. Defined a bunch of different status types
2157 as well. This replaced the old boolean registered field as well.
2159 Added resolve_cmd_ident field to the SilcClientEntry structure
2160 too so that if the entry is for example being resolved so
2161 another command may attach to the same pending command reply
2162 without requiring to resolve the same entry again. This concept
2163 should optimize the WHOIS and the IDENTIFY resolving under
2164 heavy load by taking away unnecessary resolving for entries
2165 that are being resolved already.
2167 Added support for adding multiple pending commands for one
2168 command idenfier. Affected file silcd/command[_reply].[ch].
2170 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2171 before deleting the data. Otherwise the hash table will have
2172 freed data in comparison functions. Affected file is
2173 silcd/command_reply.c.
2175 * Fixed silc_idlist_replace_client_id to add the new entry to
2176 the cache with NULL nickname. Otherwise there will be invalid
2177 memory as the nickname after the nickname is freed. Affected
2178 file silcd/packet_receive.c.
2180 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2181 saved into wrong slots because the previous number of entries
2182 was not taken into account. Affected file silcd/idlist.c.
2183 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2185 * If we are router and we receive JOIN notify to a channel that
2186 does not have any users then notified client is marked as the
2187 channel founder, as it is it. The affected file is
2188 silcd/packet_receive.c
2190 * Added to the extended hash table API's table_del_*ext functions
2191 the destructor as argument too, so that the caller can decide
2192 which destructor to use or whether to use destructor at all.
2193 Affected file lib/silcutil/silchashtable.[ch].
2195 * Fixed ID Cache purging. It actually deleted the entries from
2196 the hash table after the data was freed. The hash table ended
2197 up comparing freed memory. The affected file is
2198 lib/silccore/silcidcache.c.
2200 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Fixed Irssi SILC client's KILL command's HELP syntax.
2204 * The USERS command now resolves the detailed user information
2205 if the userinfo field is missing. Affected file is
2206 lib/silcclient/command_reply.c.
2208 * Do not print error in silc_file_read if the read file does
2209 not exist. Just silently return NULL. Affected file is
2210 lib/silcutil/silcutil.c.
2212 * Fixed the silc_log_output to not wine about NULL filename
2213 and to not create some bogus " " filename. Affected file is
2214 lib/silcutil/silclog.c.
2216 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Fixed various printing bugs on the user interface in the
2219 Irssi SILC Client. Minor changes that were forgotten from
2222 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Fixed the configure.in.pre and the compilation and distribution
2225 environment to support the new autoconf 2.52. That version is
2226 now required to compile the CVS trunk.
2228 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2231 to generally parse user@fqdn format strings. Affected file
2232 lib/silcutil/silcutil.c.
2234 * Added nickname_format and nickname_force_format fields to the
2235 SilcClientParams structure. The first one defines the format
2236 for the nicknames that the library will enforce if the receives
2237 multiple same nicknames. The second one is boolean value and
2238 can be used to force the library to always enforce the format
2239 to the nicknames regardles whether there are multiple nicknames
2240 or not. This configurable formatting was employed to flexibly
2241 support accessing multiple nicknames from the user interface.
2242 The userinterface can now set the nicknames to what ever format
2243 they prefer. Affected file lib/silcclient/silcapi.h.
2245 Added function silc_client_nickname_format to the file
2246 lib/silcclient/idlist.c. It performs the nickname formatting.
2248 Added new field `hostname´ to the SilcClientEntry context.
2249 It holds the hostname of the client. Affected file is
2250 lib/silcclient/idlist.h.
2252 * Irssi SILC Client sets the nicknames in nick@hostn format.
2253 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2254 irssi/src/silc/core/silc-core.c.
2256 The WHOIS printing now also shows both the real nickname and
2257 the formatted nickname so that user knows how to access the
2258 user if there are multiple same nicknames cached. Affected
2259 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2260 printing formatting too to take the hostname now as a separate
2261 argument. The Affected file is
2262 irssi/src/fe-common/silc/modules-formats.[ch].
2264 * Changed the silc_client_get_clients_local to accept the formatted
2265 nickname as argument. It accepts the real nickname too but the
2266 formatted nickname can be used to find the true entry from
2267 multiple entries. Affected file lib/silcclient/silcapi.h and
2268 lib/silcclient/idlist.c.
2270 * Added nickname_format_parse field to the SilcClientParams.
2271 It is a callback function provided by the application to parse
2272 the nickname out of the formatted nickname string. The library
2273 calls it to get the nickname from the formatted string. Since
2274 the application generally knows better the format of the nickname
2275 string it parses it instead of the library, even though library
2276 encodes the formatted string. If the callback function is not
2277 provided then the library will use the string as is. The
2278 affected file is lib/silcclient/silcapi.h.
2280 * All the nickname strings passed to the client library in
2281 commands are now expected to be formatted nickname strings.
2282 If the command does not support the formatted nickname string
2283 it will assume that the sent string is the actual nickname.
2284 Affected file lib/silcclient/command.c.
2286 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Added public key authentication support to OPER and SILCOPER
2289 commands in the client library. Affected file is
2290 lib/silcclient/command.c.
2292 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Changed the get_auth_methdod client operation to be asynchronous.
2295 It can be async if the application resolves the authentication
2296 method from the server during the negotiation. Added new
2297 SilcGetAuthMeth completion callback that the application will
2298 call after resolving the authentication method.
2300 Added function silc_client_request_authentication_method that
2301 the application can use to resolve the authentication method
2302 from the server. Added also SilcConnectionAuthRequest callback
2303 that the library will call after the server has replied. The
2304 application can call this function if it does not know the
2305 current authentication method.
2307 Affected files are lib/silcclient/client.c and
2308 lib/silcclient/silcapi.h.
2310 * The Irssi SILC client now automatically resolves the authentication
2311 method incase any configuration information is not present (and
2312 currently there never is). The affected file is
2313 irssi/src/silc/core/client_ops.c.
2315 * Fixed public key authentication from the client library.
2316 Affected file lib/silcclient/protocol.c. Changed also the
2317 protocol specification about the public key authentication in
2318 the connection authentication protocol. The actual data to be
2319 signed is now computed with a hash function before signing.
2321 * Fixed the public key authentication from the server as well.
2322 Affected file silcd/protocol.c.
2324 * Removed the mlock()'s from the memory allocation routines.
2325 Affected file lib/silcutil/silcmemory.c. The ./configure does
2326 not check anymore for the mlock(). Affected file is
2329 * Fixed USERS command in server to allow the execution of the
2330 command for private and secret channels if the client sending
2331 the command is on the channel. Affected file silcd/command.c.
2333 * Fixed silc_client_get_clients_local to return the clients
2334 count correctly. It could return wrong value. Affected file
2335 lib/silcclient/idlist.c.
2337 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2340 types. The assembler optimizations seemed not to like 64-bit
2341 data types. The assmebler optimizations thus are now enabled
2342 also for BSD systems as opposed to only enable them for Linux.
2344 * Do not check for threads at all on BSD systems. Affected
2345 file configure.in.pre.
2347 * Removed -n and -h options from the Irssi SILC Client since
2348 they are not used in silc.
2350 * Fixed the prime generation to assure that the first digit
2351 of the generated random number is not zero since our conversion
2352 routines does not like number strings that starts with zero
2353 digit. If zero digit is seen the random number is regenerated.
2354 This caused some corrupted RSA keys when the zero first digit
2355 was met. Affected file lib/silcmath/silcprimegen.c.
2357 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Fixed WIN32 configuration in the ./configure script.
2360 Fixed to include xti.h on environments that has it.
2361 Patches by Carsten Ilchmann and andrew.
2363 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Changed the silc_id_create_client_id to be collision
2366 resistant. It is now assured that there cannot be created
2367 two same client ID's. I suspect that some weird bugs in
2368 the server were actually caused by duplicate Client IDs.
2369 Affected file silcd/serverid.[ch]. A router receiving
2370 new ID now also assures and informs the sending server
2371 if the ID caused collision.
2373 * Changed the silc_id_create_channel_id to also assure that
2374 there are no collisions.
2376 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Statement about ignoring the Mutual Authentication flag when
2379 performing rekey with PFS was a bit misleading. It is ignored
2380 if it was set in the initial negotiation, it cannot be even
2381 set in the rekey. Fixed in the ke-auth draft. Started the
2382 new versions of the protocol drafts in the doc/.
2384 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Fixed a bug in silc_client_command_identify_save when saving
2387 new channel information. The channel name was no duplicated
2388 and caused crash on exit. Affected file is
2389 lib/silcclient/command_reply.c.
2391 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Fixed the getkey command handling in the server. Send just
2394 empty OK reply to the sender if the key could not be fetched
2395 (but everything else was ok, like the key just was not available).
2396 Changed the public key parameter to optional in the protocol
2397 specs so that empty OK reply can be sent. Affected file
2400 Added a message to Irssi SILC client to tell to user if the
2401 server did not return a public key.
2403 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Fixed a channel key regeneration bug. It registered new
2406 timeout tasks exponentially until all system resources were
2407 used. Affected file silcd/server.c.
2409 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Added the SILC Document generator to the scripts/silcdoc.
2412 It can be used to generate the Toolkit Reference Manual out
2413 of the source tree. Internally it will also use the RoboDoc
2414 generator now imported in util/robodoc.
2416 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Added couple of return's in rekey protocol if error orccurred
2419 during the protocol. The execution must be terminated.
2420 Affected file silcd/protocol.c. Also, terminate the protocol
2421 always with timeout.
2423 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * The client's Client ID was created initally from the wrong
2426 nickname (it could have been in format nick@host) in the
2427 silc_server_new_client. Affected file silcd/packet_receive.c
2429 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Added some SILC_LOG_ERROR's to various error conditions
2432 if client could not be added to ID cache. Affected files
2433 silcd/packet_receive.c and silcd/server.c.
2435 * When client's sock->user_data is freed, NULL also the
2436 client->router and client->connection pointers. Added check
2437 for these pointers being NULL to various places around the
2438 code. Affected file silcd/server.c.
2440 * Added client->data.registered == TRUE checks to various
2441 places around the code to assure that unregistered client's
2442 are not handled when it is not allowed. Affected file
2445 * Added `bool registered' fields to all
2446 silc_idlist_[server|client]_get_* routines to indicate whether
2447 the fetched client needs to be registered or not. Affected
2448 file silcd/idlist.[ch].
2450 * Add your own entry as registered to the ID cache in the
2451 server. Affected file server.c.
2453 * Fixed a bug in silc_server_new_server. The SilcServer was
2454 set as the new server's context instead of SilcServerEntry.
2455 This naturally caused some weird bugs.
2457 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Do not delete the channel rekey task when adding it
2460 for in silc_server_create_channel_key.
2462 * Changed the silc_server_create_channel_key to return
2463 TRUE or FALSE to indicate the success of the channel key
2466 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Fixed MSVC++ project files and added missing files to
2469 Makefiles under win32/.
2471 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Do not add TCP_NODELAY flag if the operating system
2474 does not have it defined. Affected files are
2475 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2477 * Fixed buffer overflow from Irssi SILC Client. Affected
2478 file irssi/src/fe-common/core/themes.c.
2480 * Fixed double free in client library in the file
2481 lib/silcclient/client.c when disconnecting from server.
2483 * Applied double free patch from cras to Irssi SILC client.
2484 Affected files irssi/src/core/[modules/expandos].c
2486 * Fixed the disconnection handling to Irssi SILC Client.
2487 The application must call silc_client_close_connection
2488 in ops->connect client operation in case of failure of
2489 the connection. Affected file is
2490 irssi/src/silc/core/client_ops.c.
2492 * Do not set sock->protocol to NULL in the function
2493 silc_client_close_connection after executing the protocol's
2494 final callback since the sock might not be valid anymore.
2495 Affected file lib/silcclient/client.c.
2497 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Do not enable SILC_THREADS if the linking with libpthread
2500 did not happen. Affected file configure.in.pre.
2502 * Added notion to protocol specification that server must
2503 verify the sent authentication payload with CMODE when
2504 setting the channel founder key. Implemented it to the
2505 server. Affected file silcd/command.c.
2507 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Added _EXTRA_DIST SILC distribution variable to the
2510 distributions file. It is used to conditionally add extra
2511 files or directories to the specific distribution. Affected
2512 files ./prepare, Makefile.am.pre and distributions.
2514 Removed the `_' from the start of the distribution names.
2517 * Added README.WIN32 for instructions to compile the Toolkit
2520 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Fixed a double free in disconnection in the server. Affected
2523 file is silcd/server.c.
2525 * Fixed the lib/silcske/groups.c to work now also with GMP
2526 MP library. The string conversion did not work when using
2527 specific base and the base is indicated in the string as well.
2529 * Created win32/ directory which now includes MSVC++ specific
2530 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2531 It will appear only in the toolkit distribution
2533 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Changed the key material distribution function in case when
2536 the hash output is too short. The data is now concatenated
2537 a bit differently than it used to. Made the change to the
2538 SKE protocol specification.
2540 * Added better GMP detection to configure.in.pre. A patch
2543 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Fixed a minor bug in SKE that might cause some problem on
2546 some platforms. Affected file lib/silcske/silcske.c.
2548 * Added the cookie checking for initiator in the SKE. It checks
2549 that the responder returns the sent cookie unmodified. The
2550 affected file is lib/silcske/silcske.c. Added new SKE
2551 error type INVALID_COOKIE that can be sent during the
2552 negotiation. Fixed some memory leaks as well.
2554 * Added the "invalid cookie" error message to Irssi SILC client's
2557 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Added `task_max' field to the SilcClientParams to indicate
2560 the maximum tasks the scheduler can handle. If set to zero,
2561 default values are used. Affected file lib/silcclient/silcapi.h.
2563 * Fixed memory leaks in silc_client_close_connection. Affected
2564 file lib/silcclient/client.c.
2566 * Added silc_client_del_client_entry to client library to free
2567 all memory of given client entry. Affected file is
2568 lib/silcclient/idlist.[ch].
2570 * Added new functions silc_client_del_channel and
2571 silc_client_del_server to delete channel and server entries.
2572 Affected file lib/silcclient/[silcapi.h/idlist.c].
2574 * Removed silc_client_del_client_by_id from silcapi.h.
2576 * Fixed the INFO command to return the server's own info
2577 correctly when querying by Server ID. Affected file is
2580 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Removed the non-blocking settings in WIN32 code in the
2583 silc_sock_[read/write] and added SleepEx instead. Affected
2584 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2585 of input data is now checked with FIONREAD and ioctlsocket.
2587 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Call silc_schedule_task_del_by_context in the
2590 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2591 Affected file lib/silccore/silcprotocol.c.
2593 * Call silc_protocol_cancel for active protocols in the
2594 silc_server_close_connection if the funtion
2595 silc_server_free_sock_user_data has not been called.
2596 Affected file silcd/server.c.
2598 * Generic tasks cannot be deleted using the del_by_fd
2599 task deleting function since generic tasks does not match
2600 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2602 * Added a notion to SILCOPER help file that the SILCOPER works
2603 only on router server, not on normal server.
2605 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Added for WIN32 support for the new scheduler as well.
2608 Affected file lib/silcutil/win32/silcwin32schedule.c.
2610 * Fixed the SHA1 implementation to work on various platforms.
2612 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2615 API. It is part of the scheduler now. Everything else is
2616 as previously but some functions has changed their names.
2617 Checkout the lib/silcutil/silcschedule.h for the interface.
2618 Updated all applications to use the new interface. Affected
2619 files are lib/silcutil/silcschedule.[ch].
2621 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Found a bug in the SKE implementation. The HASH value,
2624 specified by the protocol, was not computed correctly. The
2625 public key of the responder was not added to the computation
2626 even though it is mandatory. Affected file lib/silcske/silcske.c.
2627 This unfortunately causes incompatibilities with older
2628 clients and servers.
2630 * Added WIN32 specific network init and uninit functions:
2631 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2632 the Winsock2. Affected file lib/silcutil/silcnet.h and
2633 lib/silcutil/win32/silcwin32net.c.
2635 * Set the socket always to nonblocking mode on WIN32 after
2636 reading data or writing data. Affected file is
2637 lib/silcutil/win32/silcwin32sockconn.c.
2639 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Fixed various compilation problems under WIN32. Affected
2642 files lib/silcutil/win32/silcwin32thread.c and
2643 lib/silcutil/win32/silcwin32schedule.c.
2645 * Removed all _internal.h #includes from public header
2646 files. Internal headers must never be included from
2649 Removed also the lib/silcske/payload_internal.h file.
2651 * All include files that may be needed (public and some others
2652 included by the public headers) by application developers are
2653 now copied to the ./includes directory. It does not copy any
2654 internal headers. Affected file Makefile.defines.pre and all
2655 Makefile.am's under lib/ and subdirs.
2657 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * Do not change the ~/.silc directory's permissions automatically.
2660 Affected file irssi/src/silc/core/clientutil.c.
2662 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Do not cancel the protocol in silc_server_close_connection
2665 it might cause recursion. Now cancelled in the function
2666 silc_server_free_sock_user_data. Affected file silcd/server.c.
2668 * Fixed the silc_server_remove_clients_by_server to regenerate
2669 the channel keys correctly finally. Added also new function
2670 silc_server_remove_clients_channels to actually do it.
2671 Affected file silcd/server.c.
2673 * Fixed the silc_server_new_channel to not crash by giving
2674 wrong router to the new channel. Affected file is
2675 silcd/packet_receive.c.
2677 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2680 which is given as argument to the silc_client_alloc now.
2681 It can be used to configure the client and set various parameters
2682 that affect the function of the client.
2684 * The USERS command in server did not check whether the channel
2685 is private or secret. Affected file silcd/command.c.
2687 * Added new argument to the USERS command in protocol specification.
2688 The USERS command now can take the channel name as argument
2689 as well. Added support for this in client and server and
2690 updated the protocol specs.
2692 * Completed the GETKEY command in client. It can be now used
2693 to fetch also servers public key not only some clients.
2694 Affected files lib/silcclient/command[_reply].c.
2696 * Added silc_client_get_server to return server entry by the
2697 server name. Affected files lib/silcclient/silcapi.h and
2700 * Redefined the IDENTIFY command in protocol specification to be
2701 more generic. It now can be used to query information about
2702 any entity in the SILC Network, including clients, servers and
2703 channels. The query may be based either the entity's name
2704 or the ID. Added support for this in both client and server.
2706 Affected files silcd/command.c and lib/silcclient/command.c
2707 and command_reply.c.
2709 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2710 the _from_client and _from_server functions. Affected file
2713 * Added silc_client_get_channel_by_id_resolve to the file
2714 lib/silcclient/silcapi.h to resolve channel information by
2715 its ID. Added also silc_client_get_channel_by_id that
2716 does not resolve it from the server.
2718 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Added SilcServerEntry context into the client library
2721 to represent one server. The INFO command now allocates
2722 these to save the resolved server info. For now on the
2723 client library will also keep information about servers,
2724 connected and resolved with INFO.
2726 The INFO command now allocates the SilcServerEntry context
2727 and saves the server info there. The COMMAND_REPLY in
2728 the INFO now returns the parameters to application in
2729 same order as defined in the protocol specification.
2731 The entries are cached in the client->server_cache.
2733 * The INFO command is now issued after received the Client ID
2734 from the server. Affected file lib/silcclient/client.c.
2736 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2737 to the application as the mode changer might be server.
2738 It is guaranteed that NULL is not returned anymore to the
2739 application. Affected file lib/silcclient/client_notify.c.
2741 The ID Type is now also passed to the application so that
2742 it can check whether the returned entry is SilcClientEntry
2745 Added new function silc_client_get_server_by_id to return
2746 the server entry by ID. Affected files are the
2747 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2749 * Do not create the channel in the Irssi SILC Client when issuing
2750 the JOIN command but when received the sucessful JOIN command
2751 reply. Otherwise the channel might get created even though we
2752 could not join it. The Affected file is
2753 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2755 * Fixed a channel joining bug in router. The router must also
2756 check the channel modes, invite and ban lists etc. when serving
2757 the JOIN command sent by normal server. Affected file is
2758 silcd/command.c. The router now resolves the client's
2759 information from the server who sent the JOIN command if it
2760 does not know it, and processes the JOIN command only after
2763 * Changed the SilcCommandCb to take new argument; void *context2.
2764 Affected file lib/silccore/silccommand.h
2766 The second argument in the command callbacks in the server now
2767 includes the SilcServerCommandReplyContext if the command was
2768 called as pending command callback from the command reply.
2769 Otherwise it is NULL. When called as pending the status of the
2770 command reply will be checked and if it was erronous the
2771 error will be sent to the original sender of the command.
2772 This way the client always receives the error messages even
2773 though the server was actually the one who received the error
2774 when it resent the command to router, for example. Affected
2775 files silcd/command[_reply].[ch].
2777 * Fixed sending WHOWAS command's error message to client if
2778 the requested client could not be found. It was missing.
2781 * Changed the CMODE and CUMODE commands reply arguments in the
2782 protocol specification. The Channel ID is now sent in both
2783 of the commands to identify the channel. Implemented this
2784 new feature to the client and server. Affected files
2785 lib/silcclient/command_reply.c and silcd/command.c.
2787 * Made better checks for invite and ban lists in the JOIN
2788 command in server. Affected file silcd/command.c.
2790 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * The server now performs the incoming host IP/DNS lookup
2793 using the silc_socket_host_lookup and thus does not block
2794 the server anymore. Affected file silcd/server.c.
2796 * Completed the multi-thread support for SILC Scheduler in
2797 the lib/silcutil/silcschedule.c.
2799 * Fixed the configure.in.pre to detect the pthread correctly
2802 * Fixed a deadlock in silc_task_queue_wakeup in the file
2803 lib/silcutil/silctask.c.
2805 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Added new function silc_schedule_wakeup that is used in
2808 multi-threaded environment to wakeup the main thread's
2809 schduler. It needs to be used when a thread adds a new task
2810 or removes a task from task queues. After waking up, the
2811 scheduler will detect the task queue changes. If threads
2812 support is not compiled in this function has no effect.
2813 Implemented the wakeup mechanism to both Unix and WIN32
2814 systems. Affected files are lib/silcutil/silcschedule.[ch],
2815 lib/silcutil/unix/silcunixschedule.c and the
2816 lib/silcutil/win32/silcwin32schedule.c.
2818 * Added new function silc_task_queue_wakeup to wakeup the
2819 scheduler by the specified task queue. Affected file
2820 lib/silcutil/silctask.[ch].
2822 * The silc_socket_host_lookup_start now wakes up the scheduler
2823 after adding the timeout task. Affected file is
2824 lib/silcutil/silcsockconn.c.
2826 * The silc_socket_host_lookup is synchronous now if the threads
2827 support is not compiled in. However, the callback is still
2828 called asyncronously through the scheduler, anyway. Affected
2829 file lib/silcutil/silcsockconn.c.
2831 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Added new function silc_socket_host_lookup to perform
2834 asynchronous IP and FQDN lookups for the socket connection.
2835 Affected files lib/silcutil/silcsockconn.[ch].
2837 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2840 that may or may not compile the mutex support in.
2842 Changed the silc_mutex_alloc interface. It allocates the
2843 mutex now to the sent pointer and returns TRUE or FALSE.
2845 Affected file lib/silcutil/silcmutex.h.
2847 * Wrote the SILC Task Queue interface to support multi-threads.
2848 Affected file lib/silcutil/silctask.[ch].
2850 * Wrote the SILC Scheduler to support multi-threads. Affected
2851 file lib/silcutil/silcschedule.c.
2853 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2856 in lib/silcutil/win32/.
2858 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Defined SILC Mutex API and SILC Thread API and implemented
2861 them for Unix. Affected files are
2862 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2863 lib/silcutil/unix/silcunixmutex.c and
2864 lib/silcutil/unix/silcunixthread.c.
2866 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Fixed the silc_server_remove_clients_by_server's channel
2869 key re-generation. The hash table handling was incorrect
2870 and would not work with many channels. Affected file is
2873 * Fixed some memory leaks around the server code.
2875 * Rewrote the silc_server_get_users_on_channel to support IPv6
2876 based Client ID's. Affected file silcd/server.c.
2878 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2879 specification. However, a separate document must be written
2880 to define the detailed signing procedure and the payload
2881 associated with the flag. Defined the flag to the
2882 lib/silccore/silcchannel.h as well.
2884 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * Changed the dynamic tables to static size tables in the
2887 lib/silccrypt/silchmac.c.
2889 * Removed GCC dependencies from the code. A patch by cras.
2891 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Do not show the error "Error receiving packet bla bla"
2894 in server if it really was not an error (-2 means that reading
2895 is pending). Affected file silcd/server.c.
2897 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Fixed a possible crash in silc_server_remove_clients_by_server
2900 in silcd/server.c. Fixed there also some memory leaks.
2902 * Fixed the silc_idlist_replace_client_id. It could replace
2903 wrong key in the hash table. Affected file silcd/idlist.c.
2905 * Do not check whether there are global users on the channel
2906 if the channel->global_users is FALSE. Affected functions
2907 silc_server_remove_from_one_channel and
2908 silc_server_remove_from_channels in silcd/server.c. Also,
2909 do not check if the removed client is local as we can be
2910 sure that global client was not removed from the channel
2911 and checking for global users is not needed.
2913 * The silc_server_remove_clients_by_server now re-generates
2914 the channel keys correctly for those channels that had
2915 clients removed from them. Affected file silcd/server.c.
2917 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Found the reason of random crashes in the server. We weren't
2920 ignoring the SIGPIPE signal (which can be sent in write())
2921 and it crashed the server. Affected file silcd/silcd.c.
2923 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Assure that sock->user_data is not NULL in the function
2926 silc_server_packet_send in silcd/packet_send.c.
2928 * Disconnect the remote connection if it could not be added
2929 to any ID lists in the server. The affected file is
2932 * Check in silc_server_packet_send[_real/dest] that the
2933 socket is not disconnecting and ignore the data if it is.
2934 Affected file silcd/packet_send.c.
2936 * Define inline to __inline on native WIN32 compilation.
2937 Affected file includes/silcwin32.h.
2939 * Added some explicit type casts for inline code since MSVC
2940 require them. Affected files lib/silcutil/silcbuffer.h,
2941 lib/trq/silcdlist.h and lib/trq/silclist.h.
2943 * Print warning in log files from now on if the packet
2944 decryption fails. Affected file silcd/server.c.
2946 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Changed the `say' client operation's interface to accept
2949 new `type' argument to indicate the type of the message sent
2950 by the library. The application may filter the library's
2951 messages according the type. The affected file is the
2952 lib/silcclient/silcapi.h.
2954 * Added two new functions to lib/silcclient/silcapi.h:
2955 silc_client_del_client and silc_client_del_client_by_id.
2956 Affected file lib/silcclient/idlist.c.
2958 * Moved the clientincludes.h from includes/ to silc/ and
2959 serverincludes.h from includes/ to silcd/.
2961 * The modes for the CMODE and CUMODE are now passed as
2962 uint32 for application with COMMAND_REPLY. The affected
2963 file is lib/silcclient/command_reply.c.
2965 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * /WHOIS without arguments shows client's own information.
2968 Affected file lib/silcclient/command.c.
2970 * Changed PING to not accept any arguments. The specs
2971 says that client can ping only the connected server so
2972 requiring an argument is not needed. Affected file is
2973 lib/silcclient/command.c.
2975 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Fixed a fatal bug in private message sending and reception
2978 encryption and decryption when using private message keys.
2979 The implementation was incorrect and did not follow the
2980 specification. It causd that some of the message were
2981 lost since it did not use the sending and receiving keys
2982 as the protocol suggests. This has been fixed and will cause
2983 incompatibilities with older clients when sending private
2984 message encrypted with private message keys. Affected files
2985 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2986 and various other in Irssi SILC Client.
2988 Added `responder' boolean argument to the functions
2989 silc_client_add_private_message_key[_ske] to indicate when
2990 the key is added as responder or initiator of the key
2993 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Removed the silc_ske_check_version function and created
2996 a SilcSKECheckVersion callback. Added also a function
2997 silc_ske_set_callbacks that is now used to set all SKE
2998 callbacks. The callback functions are not given to
2999 the SKE functions anymore, but this function is used to
3002 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3004 * Added `silc_version' argument to the silc_client_alloc
3005 to define the version of the application for the library.
3006 The library will use the version string to compare it
3007 against the remote host's (usually a server) version
3008 string. Affected file lib/silcclient/silcapi.h
3010 * Added the KE protocol context to Key Agreement context
3011 in client library so that we can abort the SKE if it
3012 is in process when we get timeout. Affected file is
3013 lib/silcclient/client_keyagr.c.
3015 * Do not resolve the client ID forever if it returns in the
3016 first time that such client does not exist. This was done
3017 for example with private message. Affected file is
3018 lib/silcclient/client_prvmsg.c.
3020 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Do not add regex.h for WIN32. The affected file
3023 includes/silcincludes.h.
3025 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3026 not work yet 100%. It generates the DLL's automatically
3027 when compiling with --with-win32 under cygwin.
3029 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * lib/contrib/regex.c is not compiled on WIN32.
3033 * Added silc_net_get_socket_opt function to the
3034 lib/silcutil/silcnet.h.
3036 * Added includes/silcwin32.h for WIN32 specific includes
3039 * Do not use ptime structure or any of the posix process
3040 functions on WIN32 in lib/silccrypt/silrng.c.
3042 * Added silc_gettimeofday to provide generic function
3043 for struct timeval on all platforms. Added the function
3044 to lib/silcutil/silcutil.h.
3046 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3049 library as they clearly belong there. As a plus side we
3050 can make the actual socket connection routines platform
3053 Added also new generic function silc_socket_read and
3054 silc_socket_write (that used to be silc_packet_[read/write].
3055 The implementation of these are platform specific.
3057 * Added WIN32 specific routines of silc_socket_[read/write]
3058 to lib/silcutil/win32/silcwin32sockconn.c.
3060 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * Added preliminary support for native WIN32 compilation under
3063 cygwin (using the -mno-cygwin option for GCC) to the
3064 ./configure.in.pre. The --with-win32 now prepares the
3065 compilation for native WIN32.
3067 * Rewrote the SILC Scheduler interface in the file
3068 lib/silcutil/silcschedule.h. The scheduler is now context
3069 based and does not have anymore any global static scheduler.
3070 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3071 and created lib/silcutil/win32 directory for WIN32 based
3074 * Added Unix specific network routines to the
3075 lib/silcutil/unix/silcunixnet.c and the old
3076 lib/silcutil/silcnet.c includes now only generic routines.
3078 Added WIN32 specific network routines to the
3079 lib/silcutil/win32/silcwin32net.c.
3081 * Added Unix specific utility functions from the
3082 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3084 * Added WIN32 SILC Scheduler to the file
3085 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3088 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3090 * Do not handle JOIN notify in the server if the target client
3091 is not registered (idata->registered == FALSE). The affected
3092 file is silcd/packet_receive.c.
3094 * Update the nickrec->founder in event_cumode in the Irssi SILC
3095 client. Affected file irssi/src/silc/core/silc-channels.c.
3097 * Fixed the CUMODE_CHANGE notify handling in the server when
3098 server and router are announcing their clients on channels.
3099 Now the mode changes are saved and notified correctly. The
3100 affected file is /silcd/packet_receive.c.
3102 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3103 They really did not replace the cache entry in the ID Cache.
3104 Now they do that. Affected file silcd/idlist.c.
3106 * Fixed the KICK notify handling in the Irssi SILC client to
3107 update the channel records so that the kicked client does not
3108 appear to be on the channel. The affected file is
3109 irssi/src/silc/core/silc-channels.c.
3111 * Always update the conn->current_channel when executing command
3112 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3114 * Fixed the KILL notify handling in Irssi SILC client to remove
3115 the killed client on all channels.
3117 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Fixed the silc_parse_command_line to remove extra spaces
3120 from the start and end of the arguments. Affected file is
3121 lib/silcutil/silcutil.c.
3123 * Cancel and free any active protocol in the function
3124 silc_server_close_connection. Affected file silcd/server.c.
3126 * Cancel and free any active protocol in the function
3127 silc_client_close_connction. Affected file is
3128 lib/silcclient/client.c.
3130 * Do not execute the KILL command for clients that are in
3131 history (ie. they are not in the network). Affected file is
3134 * Fixed KILL notify handling, client does not crash anymore.
3135 Affected file irssi/src/silc/core/silc-channels.c.
3137 * Reduced the default packet buffer size from 2048 to 1024 in
3138 lib/silccore/silcpacket.c.
3140 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3141 counter to the SKE context that is incresed when the SKE library
3142 performs async operation outside the library. If the outside
3143 process frees the SKE context and FREED status will be set
3144 and the library will detect after the sync operation that the
3145 libary is freed. The affected files are
3146 lib/silcske/silcske[_status].[ch].
3148 * Resolve the client entry information in the function
3149 silc_client_channel_message to assure that NULL pointer is not
3150 passed as client entry to the application. */
3152 * Fixed the task timeout calculation to assure that there is
3153 never negative timeouts. The affected file is
3154 lib/silcutil/silcschedule.c.
3156 * Fixed the channel user mode notification sending in server.
3157 It was sent point-to-point to the router (or to server by router)
3158 but it needs to be destined to a channel. The routines now
3159 supports sending the channel user mode notifys to the channels
3160 when announcing clients and channels. Affected files are
3161 silcd/server.c and silcd/packet_receive.c.
3163 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3164 It did not actually replace the old channel entry in the cache.
3165 Affected file lib/silcclient/client_notify.c.
3167 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Fixed a possible crash in silc_packet_send_prepare. It now
3170 assures always that there is enough space in the buffer and
3171 at the tail area of the buffer (for MAC).
3173 Fixed the inbound buffer reallocation in silc_packet_read.
3174 It was old code and did not handle the reallocation correctly.
3177 The affected file is lib/silccore/silcpacket.c.
3179 * Fixed buffer overflow in silc_parse_nickname in the file
3180 lib/silcutil/silcutil.c.
3182 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * make install generates new server keys only if there is not
3187 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3190 Added check that if the NOREPLY is set then we will not send
3191 the away message. This avoids infinite loop of away messages
3192 if both clients are away. The affected file is
3193 lib/silcclient/client_prvmsg.c.
3195 * Fixed client crash if /NICK was given without arguments.
3196 Affected file lib/silcclient/command.c.
3198 * Server does not send the invite list in INVITE command back
3199 to the client if the list was not altered. Added this notion
3200 to the protocol spec as well. Affected file silcd/command.c.
3202 Fixed possible crash in INVITE command by checking the
3203 value of silc_server_get_client_route command.
3205 * Fixed the INVITE notify type handling. The arguments are now
3206 taken in correct order and client does not crash. The affected
3207 file is irssi/src/silc/core/silc-channels.c.
3209 Removed the "Inviting xxx to channel" message from the
3210 client library away and let the application handle it.
3211 Affected file lib/silcclient/command.c. Added that message
3212 to Irssi SILC client's message formats.
3214 * Fixed CMODE command crash in client. It now checks the
3215 amount of arguments correctly and does not crash. The affected
3216 file is lib/silcclient/command.c.
3218 * Do not create new channel automatically in silc_channels_join
3219 but check whether the channel by that name already exists.
3220 Affected file irssi/silc/core/silc-channels.c.
3222 * Do not send the SERVER_SIGNOFF to router if the disconnected
3223 entity was the router. Affected file silcd/server.c.
3225 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3226 SILC client as it was missing from there.
3228 Added the handling of the KICK notify to the Irssi SILC client
3229 as it was missing. Added "you have been kicked" message to
3230 Irssi SILC client's message modules formats.
3232 Added the handing of the KILL notify to the Irssi SILC client
3233 as it was missing. Added the kill message module formats
3236 The affected file is irssi/src/silc/core/silc-channels.c.
3238 * The router did not save the channel mode the server announced.
3239 Affected file silcd/packet_receive.c.
3241 * Fixed a possible crash in INFO command in server. If the
3242 server did not provide the server info it crashed. Affected
3243 file silcd/command.c.
3245 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Fixed the GETKEY command in the server to check also the
3248 global list. Otherwise the GETKEY would not work correctly
3249 in normal SILC server. Affected file silcd/command.c.
3251 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Fixed GETKEY crash, it crashed if the command did not succseed.
3255 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3258 is now real and not just an macro interface to GMP.
3260 Removed the entire GMP from the source tree and imported new
3261 NSS MPI library instead. Reason for removing GMP is that it is
3262 extremely large and compiles extremely slow. The NSS MPI
3263 is only a few files and compiles in less than 10 seconds.
3264 The speed is also about the same as GMP. The MPI is imported
3265 to lib/silcmath/mpi.
3267 If the system has GMP installed we will still use the GMP.
3268 If it is not then the NSS MPI will be compiled.
3270 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Merged a long nickname (127 characters long) crash bugfix from
3273 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3275 * Merged a freed memory reference bugfix from Irssi CVS tree.
3276 Affected file irssi/src/core/commands.c.
3278 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Added the server's public key sving and verification to the
3281 server when performing the SKE. This was missing and the
3282 remote server's (or router's) public key was accepted without
3283 checking whether we have it previously or trust it at all.
3284 Affected file silcd/protocol.c.
3286 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Check in the silc_server_timeout_remote if protocol is active
3289 and make sure that the protocol's final callback is called so
3290 that all memory if freed. Affected file silcd/server.c.
3292 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * silc_server_whois_send_reply crashed the server if the nickname
3295 was 127 characters long. Affected file silcd/command.c.
3297 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added sanity check to the silc_server_new_client. If the hostname
3300 is provided inside username then check that the provided hostname
3301 really is the same as the resolved one. If the hostname was not
3302 resolved then check it from the public key. Affected file is
3303 silcd/packet_receive.c.
3305 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3306 if the server disconnected us and the connection is not valid
3307 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3309 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3310 the library to the lib/silcutil/silcutil.[ch].
3312 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Close log file after open. Affected file
3315 lib/silcutil/silclog.c.
3317 * Check whether sock == NULL in silc_client_send_packet and return
3318 if it is. Affected file lib/silcclient/silcclient.c.
3320 * Check rec->entry == NULL in the Irssi SILC Client before
3321 sending the channel message. Affecte file is
3322 irssi/src/silc/core/silc-servers.c.
3324 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Merged a splitted window bugfix from Irssi CVS tree. The
3327 affected file is irssi/src/fe-text/textbuffer-view.c.
3329 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3330 It did not print nickname.
3332 * Improved the distributions system a bit.
3334 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3337 irssi/src/fe-text/gui-window.c.
3339 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3340 to in-active server. The affected file is
3341 irssi/src/silc/core/client_ops.c.
3343 * Resolve the client in USERS command reply if the entry does
3344 not have username resolved. The affected file is
3345 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3346 command to WHOIS command to really resolve stuff. The USERS
3347 is not used any more in any critical section so WHOIS can
3348 be used even though it might be slower than IDENTIFY.
3350 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3353 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Changed the protocol API a bit more consistent in the
3356 lib/silccore/silcprotocol.[ch].
3358 * Changed the following headers to ROBODoc format:
3360 lib/silccore/silcpayload.h
3361 lib/silccore/silcprotocol.h
3362 lib/silccore/silcsockconn.h
3364 All core library headers are now formatted.
3366 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Fixed a bug in Irssi SILC client; do not show that you are
3369 server/router operator if you really are not. Affected file is
3370 irssi/src/silc/core/client_ops.c.
3372 * Renamed silc_command_free_payload to silc_command_payload_free.
3373 Affected file lib/silccore/silccommand.h
3375 * Added silcmath.h to include the prototoypes of various routines
3376 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3379 * Changed the following headers to ROBODoc format:
3381 lib/silccore/silcchannel.h
3382 lib/silccore/silccommand.h
3383 lib/silccore/silcid.h
3384 lib/silccore/silcidcache.h
3385 lib/silccore/silcmode.h
3386 lib/silccore/silcnotify.h
3387 lib/silccore/silcpacket.h
3388 lib/silcmath/silcmath.h
3390 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3392 * Added checking to the server code not to start the server if
3393 ciphers and stuff are not configured properly. Affected files
3394 silcd/serverconfig.[h] and silcd/server.c.
3396 * Changed the layout of the header files of the public interfaces
3397 in the SILC libraries. The new layout supports ROBODoc
3398 documentation tool (and some others) so that it is easy to create
3399 a library reference manual. All the other headers and source
3400 code must still follow the CodingStyle document. Also source
3401 code must not include these ROBODoc stuffs, only the headers.
3402 Furthermore, all public interface headers must now be named
3403 by using `silc' prefix, example: silcapi.h, silccipher.h.
3404 Some files were renamed due to this. All the other headers
3405 must not be used as public interfaces. I will update the
3406 CodingStyle document later. Changed following headers, so far:
3408 lib/silcclient/silcapi.h
3409 lib/silccore/silcauth.h
3410 lib/silccore/silcprivate.h
3411 lib/silccrypt/silcdh.h
3413 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Removed silc_client_packet_send_flush from the client library
3418 as it is not needed. Affected file lib/silcclient/client.[ch].
3420 * Added printing of message of unresolved authentication method
3421 to the Irssi SILC client. Added it to the module formats.
3422 Removed the same message from the client library.
3424 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Added new distribution feature, DISTLABEL. Every distribution
3427 can define own preprocessor label that can be used in the
3428 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3429 file distributions, acconfig.h.pre and prepare.
3431 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3433 * Added Makefile.defines_int to include the actual definitions
3434 for Makefile.defines.in. Tested the new distribution system,
3435 created distributions and tested installation.
3437 * Added AWAY message printing to the Irssi SILC client. Added
3438 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3440 * Added SCONNECT command to call the SILC's CONNECT command.
3441 Cannot use CONNECT directly since Irssi uses that internally.
3442 Affected file irssi/src/silc/core/silc-servers.c.
3444 Added ACTION local command. It is same as ME command but takes
3445 the channel as mandatory argument.
3447 Rewrote some of the Irssi's help files to suite for SILC
3450 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Added Makefile.defines[.in] that should for now on be included
3453 in all Makefile.am file in the source tree. That file includes
3454 all common compilation definitions for SILC source tree.
3456 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Minor changes to the ./prepare script to change the package
3459 name according the distribution name to the configure.in.
3461 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Created new distribution system. Added file `distributions'
3464 that defines all the distributions that can be created out of
3465 the SILC source tree. The ./prepare script now reads that
3466 file to determine how to prepare the distributions. The
3467 first argument to the ./prepare is the name of the distribution
3468 and second is the version of the distribution. If given
3469 without arguments it creates the default (toolkit) distribution
3470 with the default version (defined in ./prepare).
3472 All Makefile.am files that are subject to the distributions
3473 are now named as Makefile.am.pre. These are ./Makefile.am
3474 and lib/Makefile.am. Others may be changed later.
3476 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Added invite list, ban list, some key management and connection
3479 error message printing to module formats in the Irssi SILC client.
3481 * Added new silc_client_set_away_message to set the away message
3482 that is back to the person who sent private message. The
3483 affected file lib/silcclient/silcapi.h and the
3484 lib/silcclient/client_prvmsg.c.
3486 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Fixed the private message sending in the Irssi SILC client,
3489 added local command KEY to the Irssi SILC client.
3491 Added key management and key agreement message formats to the
3492 irssi/src/fe-common/silc/module-formats.[ch].
3494 Added USERS (alias WHO) printing, server/router operator
3495 indication and LIST command printing to the module formats.
3497 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Fixed channel joining notify handling, cumode notify handling
3500 from Irssi SILC client.
3502 * Added SILC specific module-formats to the Irssi SILC client so
3503 that SILC specific message hilighting, colors etc is possible.
3504 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3506 Added channel mode, channel user mode, actions, notices,
3507 whois and whowas printing to the the module-formats.c.
3509 * Fixed a bug in channel deletion in the server. The channel
3510 is not left to the cache even if the channel founder auth mode
3511 is set when there are no users anymore on the channel. Affected
3512 file silcd/server.c.
3514 * The silc_net_localhost now resolves the entire hostname including
3515 the domain name. Affected file lib/silcutil/silcnet.c.
3517 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Changed the ask_passphrase client operation to be ascynchronous.
3520 It has now a completion callback and a context that the
3521 application must call after it has got the passphrase from
3522 the user. Affected files lib/silcclient/silcapi.h,
3523 lib/silcclient/protocol.c, lib/silcclient/command.c and
3526 Added SilcAskPassphrase callback that the application calls
3527 to deliver the passphrase to the library.
3529 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3530 The public key verification and especially a certificate
3531 verification is asynchronous procedure.
3533 Added new SILC_SKE_STATUS_PENDING status to indicate the
3534 request is pending and a callback will be called to finalize
3537 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3538 indicate that remote end did not send its public key (or
3539 certificate), even though we require it. Added check for this
3540 condition in the SKE. This was a security bug, now fixed.
3542 Defined new SilcSKEVerifyCbCompletion callback that is called
3543 when the verification process is completed.
3545 The affected files lib/silcske/silcske_status.h and
3546 lib/silcske/silcske.[ch].
3548 * Changed the verify_public_key client operation to be async
3549 as well. Defined SilcVerifyPublicKey callback that is used to
3550 indicate the success of the public key verification process.
3552 Changed the server and client to use the new async client
3555 * Changed the Irssi SILC client's internal scheduler to be called
3556 twice as many times as it used to be. As a result the client
3557 should be a bit faster now. Affected file is
3558 irssi/src/silc/core/silc-core.c.
3560 * Added support to Irssi SILC client of asynchronous public key
3561 verification and passphrase inquiry. Affected file is
3562 irssi/src/silc/core/silc-core.c.
3564 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Do not say "You have left channel %s" in client library.
3567 Moved it to the application. Affected files are
3568 lib/silcclient/command.c and silc/client_ops.c.
3570 * Fixed silc_client_get_clients. Command context was not
3571 duplicated and was freed memory in the callback. Affected
3572 file lib/silcclient/idlist.c.
3574 * Do not say "you are now talking..." on JOIN command in the
3575 client library. The appliation must handle it.
3577 * Do not say ".. changed topic to" in command reply in the
3578 client libary. The application must handle it.
3580 * Fixed TOPIC command sending in the client library.
3582 * Fixed a memory leak in silc_client_command_free in the file
3583 lib/silcclient/command.c.
3585 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Imported a modified version of Irssi client to the source tree.
3588 The Irssi will be used to create a new client called
3589 Irssi SILC. Imported to irssi/.
3591 Added silc_core_init_finish function to the Irssi. Affected
3592 file irssi/configure.in.
3594 A lot changes in the Makefile.ams around the irssi tree.
3596 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Do not rehash if the new size is same as the old size of the
3599 hash table, in the silc_hash_table_rehash*. The affected file
3600 lib/silcutil/silchashtable.c.
3602 * Replaced hash_table_del_by_context calls from the server
3603 (when channel->user_list and client->channels) to the
3604 hash_table_del as it is sufficient and faster.
3606 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * Added silc_hash_table_list, silc_hash_table_get and the
3609 SilcHashTableList structure to provide an alternative way to
3610 traverse the hash table. The affected files are
3611 lib/silcutil/silchashtable.[ch].
3613 * Changed the server's idlist routines to use the hash table
3614 routines to optimize the code.
3616 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Replaced the client entry's `channel' list and channel entry's
3619 `user_list' list to hash tables for optimized lookup. Changed
3620 the code to use the hash table interface around the code.
3621 Affected file lib/silcd/idlist.[ch].
3623 * Added `auto_rehash' boolean argument to the function
3624 silc_hash_table_alloc to indicate whether the hash table should
3625 auto-rehash when it thinks is appropriate time. It will
3626 increase the hash table size if the there is twice as much
3627 entries in the table than the size of the table, and will
3628 decrease the size if there are twice as less entries than
3629 the size of the table.
3631 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3635 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * silc_idcache_purge_by_context deletes the entry now by context
3638 as it is supposed to do. Affected file lib/silccore/idcache.c.
3640 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3641 client is not anymore valid (WHOWAS givens the info) and not
3642 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3644 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Removed the `data' and `data_len' arguments from the ID Cache
3647 interfaces and added `name' argument. ID Cache does not handle
3648 anymore the binary data only a names associated with given ID.
3650 * When hashing a Client ID with silc_hash_id the entire ID is
3651 not hashed anymore, instead only the hash of the Client ID is
3652 hashed. This way we can access the Client ID from the cache
3653 with Client ID but with the hash of the ID (which is a hash of
3654 the nickname) as well without any difference in performance.
3656 Added also silc_idcache_find_by_id_one_ext to do one on one
3657 searching when we have the actual ID. Added also function
3658 silc_hash_client_id_compare. The affected files are
3659 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3661 * When hashing the name associated with a ID it is always done
3662 in lowercase. This way we can access the cache without worrying
3663 about case-sensitivity, even though, for example nicknames are
3666 * Fixed a bug in server with channel message sending. It put
3667 wrong ID type as destination ID. The affected file
3668 silcd/packet_send.c.
3670 * silc_idcache_del_by_context now deletes from all hash tables
3671 by context. Affected file lib/silccore/idcache.c.
3673 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Changed the client library to use the new ID Cache interface.
3676 Changes around the source tree.
3678 * Added silc_hash_table_rehash_ext to rehash with specific
3679 hash function. Affected file lib/silcutil/silchashtable.[ch].
3681 * Added silc_hash_string_compare to compare two strings in the
3682 hash table. Affected file lib/silcutil/silcutil.[ch].
3684 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Added new function silc_idcache_del_by_context into the
3687 lib/silccore/idcache.[ch].
3689 * Changed the server's ID list routines to use the new ID Cache
3690 interface. Changes around the source tree.
3692 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Added silc_hash_table_del[_by_context]_ext functions in to the
3695 lib/silcutil/silchashtable.[ch].
3697 Removed silc_hash_table_find_all* routines and added new
3698 silc_hash_table_find_foreach to replace them.
3700 Added silc_hash_table_replace_ext function as extended
3701 replacing function. Separated the simple hash table interface
3702 from the extended hash table interface in the file
3703 lib/silcutil/silchashtable.h.
3705 * Fixed minor bugs and changed it to use some of the new
3706 hash table functions in lib/silccore/idcache.c
3708 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Added new function silc_hash_table_find_all to return all keys
3711 in the hash table by the specified key. As the hash table is
3712 collision resistant it also makes it possible to have several
3713 duplicate keys in the hash table. This function may be used to
3714 find all of the keys from the hash.
3716 Added user_context arguments to the SilcHashFunction,
3717 SilcHashCompare and SilcHashDestructor to deliver user specified
3720 Added new fuctions silc_hash_table_find[_all]_ext to do
3721 extended lookup with specified hash and compare functions and
3722 specified user contexts.
3724 Added new function silc_hash_table_add_ext to add the key
3725 with specified hash function and user context.
3727 Added new function silc_hash_table_foreach to traverse all
3728 entrys in the hash table. Added SilcHashForeach callback
3731 Added new function silc_hash_table_del_by_context to delete
3732 the entry only if the context associated with the key matches.
3734 Affected files are lib/silcutil/silchashtable.[ch].
3736 * Removed silc_hash_[server/client/channel]_id and added just
3737 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3738 silc_hash_id_compare to compare two ID's using as the hash table
3739 comparison function. Added also silc_hash_data to hash
3740 binary data and silc_hash_data_compare to compare it.
3742 * Removed silc_idlist_find_client_by_hash as it is not needed
3743 anymore. Affected file silcd/idlist.[ch].
3745 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3746 to use internally the SilcHashTable. The new ID Cache is a lot
3747 faster than the old one. Some of the ID Cache interface was also
3748 rewritten and obsolete and stupid functions were removed.
3750 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Added entry_count field to the SilcHashTable to keep the number
3753 of the entries in the table. Implemented the function
3754 silc_hash_table_rehash. Added new function
3755 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3757 Fixed a minor bug in silc_hash_table_free.
3759 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3760 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3761 into the lib/silcutil/silcutil.[ch].
3763 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Implemented a collision resistant hash table into the
3766 lib/silcutil/silchashtable[ch]. See the header and the source
3767 for the SilcHashTable API.
3769 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Merged dotconf version 1.0.2 into lib/dotconf.
3773 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Do not compile anything in lib/silcsim/* if the SIM support
3776 is not enabled. The tree should now compile without problems
3779 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Compiled the SILC under cygwin. Compiled and tested briefly
3782 without problems. More tests needed. The SIMs didn't compile
3785 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3787 * Fixed possible crash in silc_get_username in the
3788 lib/silcutil/silcutil.c.
3790 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Fixed a va_arg in silc/client_ops.c.
3794 * Oops, RC5 routines were named AES and caused some problems
3795 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3797 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Added new SilcIDIP structure into the lib/silccore/id.h and
3800 replaced the old `ip' fields from all SILC ID's to that type.
3801 This is a step towards IPv6 support.
3803 The silc_id_get_len takes now the ID as an extra argument.
3804 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3805 both IPv4 and IPv6 based ID's.
3807 The affected files are lib/silccore/id.[ch] and other files
3808 around the tree using these routines.
3810 * Removed the ID length arguments in server from various
3811 silc_server_send_notify_* routines -> they are not needed
3814 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Fixed memory leak in silc_encode_pem_file in the file
3817 lib/silcutil/silcutil.c.
3819 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Check minor version as well in the SKE. Affected files are
3822 silcd/protocol.c and lib/silcclient/protocol.c.
3824 * Added --identifier option to the server so that an identifier
3825 can be when creating the public key for the server. Affected
3826 file is silcd/silcd.c.
3828 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3829 lib/silccrypt/silcpkcs.c.
3831 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Register default ciphers and stuff when using -C option with
3834 the server. Affected file sildc/silcd.c.
3836 * Put back the servers public key filename format, it is better
3837 than the new one. For now, the client keys are saved with the
3838 new filename format. The affected file silc/client_ops.c.
3840 * Implemented the Cipher API for the rest of the ciphers that
3841 did not implement it or implemented it the wrong way.
3843 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Register default ciphers and stuff when using the -S option
3846 in the client. Affected file silc/silc.c. Same also when
3847 creating new key pair with -C option.
3849 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Fixed the silc_verify_public_key client operation function to
3852 save the public keys differently. The fingerprint is now
3853 used as filename and not the hostname. This way also the
3854 client keys are saved uniquely and not with hostnames. The
3855 affected file is silc/client_ops.c.
3857 * Trimmed the silc_hash_fingerprint function to remove extra
3858 whitespaces from the end of the fingerprint. The affected
3859 file is lib/silccrypt/silchash.c.
3863 * Added silc_cipher_register_default function to register all
3864 default ciphers. It can be used when configuration files
3865 does not exist and the application does not want any specific
3866 ciphers in any specific order.
3868 The SilcDList is now used as silc_cipher_list dynamically
3869 allocated cipher list. Removed the static list all together
3870 and now all ciphers must be allocated to the dynamic list.
3871 The silc_cipher_alloc routine was changed to check only the
3874 All silc_cipher_* routines that used to return int returns
3877 The affected files lib/silccrypt/silccrypt.[ch].
3879 * The same thing was done to silc_hash_* as for silc_cipher_*
3880 routines. Affected files lib/silccrypt/silchash.[ch].
3882 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3883 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3884 Added also silc_pkcs_[un]register[_default] functions.
3885 Removed the data_context from the PKCS API.
3887 * Added silc_hmac_register_default function to register default
3888 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3889 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3890 to unregister all hmacs at once.
3892 * Register the default ciphers, hash functions, PKCSs and HMACs
3893 if client's configuration file does not exist. The affected
3896 * The client did not load the hash functions from the SIM
3897 modules at all. Added support for this. Affected file is
3898 silc/clientconfig.c.
3900 * When decoding public key with silc_pkcs_public_key_decode, check
3901 the supported algorithm only if PKCS are registered. Affected
3902 file lib/silccrypt/silcpkcs.c. The same was done with the
3903 silc_pkcs_private_key_decode.
3905 * Fixed the SILC List routines to keep the list always in order.
3906 It used to change the list's order when traversing the list but
3907 not it preserves the order. Affected file lib/trq/silclist.h.
3909 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Added the client library to use the SilcSocketConnection's
3912 reference counter (by silc_socket_dup) to prevent the bug that
3913 the socket object may be freed underneath async operation.
3915 * The name resolv library checking fixes in the configure.in.pre.
3918 * Created new version of the protocol drafts for future
3919 development. The -03 drafts are the ones that will be changed
3920 in the trunk now and the -02 will remain as they are.
3922 * Send list of CUMODE notifys to the router when announcing
3923 the channel users to the router. Affected file silcd/server.c.
3924 If the router receiving channel founder CUMODE for a channel
3925 that already has channel founder it will send CUMODE notify
3926 to the sender to remove the channel founder rights from the
3927 announced client. Affected file silcd/packet_receive.c.
3929 * The CUMODE notify may now use Server ID as well as the entity
3930 who changes the mode. Updated protocool specs.
3932 * Updated INSTALL and README files.
3934 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * New web pages in the http://silc.pspt.fi. The pages was
3941 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Implemented the [DenyConnectin] config section in the server.
3944 Added silc_server_config_denied_conn to check whether incoming
3945 connection is denied. Affected file silcd/serverconfig.[ch].
3947 * Do not check the ports when checking the incoming configuration
3948 data if the port is 0, meaning any. Affected file is
3949 silcd/serverconfig.c.
3951 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Fixed buffer overflow in silc_string_compare in the file
3954 lib/silcutil/silcutil.c.
3956 * Fixed double free in silc_server_command_leave in the file
3959 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Fixed the version checking in the server. Affected file is
3964 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Fixed the configuration data fetching when accepting new
3967 connections in the server. Affected file silcd/server.c.
3969 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added `sender_entry' argument to the function
3972 silc_server_packet_relay_to_channel so that we can check
3973 whether some destination actually belongs to the same route
3974 the sender belongs (ie, we must not resend the packet to the
3975 sender). Affected file silcd/packet_send.[ch].
3977 * Added `servername' field to the SilcClientEntry in the server
3978 to hold the name of the server where client is from. Affected
3979 file is silcd/idlist.h.
3981 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Moved the channel message encrypting in the router betwen
3984 router connections from silc_server_channel_message to the
3985 silc_server_packet_relay_to_channel since we want to check
3986 whether we have anybody channel before encrypting anything.
3987 Affected files silcd/packet_[receive/send].c.
3989 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Fixed the [AdminConnection] server config section to support
3992 multiple entries. Affected file silcd/serverconfig.c.
3994 * Added support into the server to check the validity of the
3995 incoming connection before executing any KE or authentication
3998 * The connection configuration is now saved to the KE and
3999 connection auth protocol contexts and not fetched anymore in
4000 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4002 * The local hosts listenning address and port is also resolved
4003 now when starting the server. We want to have the socket object
4004 to include the real address and port for the listener. Added
4005 new function silc_net_check_local_by_sock into the files
4006 lib/silcutil/silcnet.[ch].
4008 * Fixed a broadcast bug in server -> do not broadcast if we
4011 * Fixed a routing bug. Do not route broadcast packets ever.
4012 Broadcast packets must be processed always and not routed since
4013 they may be destined to some other host than yourself and thus
4014 would get routed without no good reason. Affected file is
4017 * Added function silc_server_config_is_primary_route to check
4018 whether primary router connection has been configured (a router
4019 configuration that we are initiating). If there is not, we
4020 will assume that there is only two routers in the SILC network
4021 and we will use the incoming router connection as our primary
4022 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4024 * Changed the order of the broadcasting. Broadcast _after_ the
4025 packet has been processed not before. Affected file is
4028 * Fixed a [ClientConnection] parsing bug. The port was never
4029 parsed correctly thus resulting to port 0. Affected file
4030 silcd/serverconfig.c.
4032 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4033 argument and did not set the broadcast packet flag. Affected
4034 file silcd/packet_send.c. Fixed same bug in the function
4035 silc_server_send_notify as well.
4037 * If we receive NEW_ID packet for our own ID in the server, ignore
4040 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Removed the nickname from the Private Message Payload.
4045 Updated the code and the protocol specs.
4047 * Updated protocol specs for submitting to the IETF.
4049 * Tweaked the Random Number Generator a bit. Affected file
4050 lib/silccrypt/silcrng.c. Exported a new function
4051 silc_rng_[global]_add_noise which can be used to add more
4054 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Do not parse packets with different timeout when protocol
4057 is active -> may cause problem with rekey. Affected file
4060 * When server receives signoff notify it must not create
4061 new channel key if the client is on any channels since the
4062 sender of the signoff notify will create it.
4064 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Added printing of error messages during SKE protocol from the
4067 failure packet sent by server during SKE. Affected file
4070 * Removed the client's failure_callback handling with timeout
4071 and handle it immediately when received.
4073 * The SKE library returned wrong type in SUCCESS and FAILURE
4074 packets. They must be 32 bit MSB not 16 bit MSB.
4076 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Ok, rewrote the logic of the re-key and now it seems to work.
4079 I tested it on high traffic with frequent re-keys without
4080 problems. Added hmac_receive (and renamed hmac to hmac_send)
4081 in SilcClientConnection in lib/silcclient/client.h and
4082 in SilcIDListData in silcd/idlist.h. Also, removed the
4083 SilcPacketParserContext's cipher and hmac fields as they are
4084 not needed anymore and actually caused some problems when
4085 the ciphers and hmac's changed underneath the packet parser.
4087 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * If re-key protocol is active then process the incoming packets
4090 synchronously since we must assure that icoming packets encrypted
4091 with the old key is processed before the new keys is set to
4092 use. This is true other packets than for REKEY packets.
4093 Affected file silcd/server.c. The same was done to client library
4094 as well, affected file lib/silcclient/client.c.
4096 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Fixed bug in client and server to accept the force send if
4099 the packet is send from silc_[server/client]_packet_process
4100 function. Otherwise the packets are never delivered, oops.
4102 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Disable force sending of packets when REKEY protocol is active.
4105 We must assure that no packet is sent directly when rekey is
4106 performed. All packets must be sent through packet queue.
4107 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4108 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4109 function is silc_[server/client]_packet_send_real to check
4112 * Replaced the SIM paths from example config files to
4113 /usr/local/modules. Also, make install creates now
4114 /usr/local/silc/logs directory to hold all the SILC server
4117 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Made the configure.in.pre work on Solaris. Patch by salo.
4121 * Made all ciphers compatible with non-x86 machines. Defined
4122 CBC mode macros into lib/silccrypt/ciphers_def.h.
4124 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Fixed the make install.
4128 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * When MAC computation fails the silc_packet_decrypt returned 0
4131 even though it was supposed to return -1. Fixed this. The
4132 affected file is lib/silccore/silcpacket.c.
4134 * Do not replace the config files in /etc/silc (in make install)
4135 if they already exist. Affected file ./Makefile.am.
4137 * Do not send re-key packets immediately but through packet queue.
4138 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4140 * Changed silc_net_check_host_by_sock to return FALSE if the
4141 IP/DNS could not be resolved. Though, it returns the IP address
4142 now even if it could not resolve it (but returns also FALSE).
4143 Affected file lib/silcutil/silcnet.[ch].
4145 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Added silc_pkcs_decode_identifier to decode the public key's
4148 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4149 Added also silc_pkcs_free_identifier. Added also new context
4150 SilcPublicKeyIdentifier.
4152 * Added -S option to the silc client. It is used to dump the
4153 contents of the specified public key file.
4155 * Changed the PKCS api to return the public key length when
4156 setting the public key.
4158 * Fixed a fatal bug in the public and private key file loading.
4159 Affected file lib/silccrypt/silcpkcs.c.
4161 * Execute the packet parsing for client with zero (0) timeout
4162 if the protocol is active. Affected file silcd/server.c.
4164 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Made the key generation options to the silcd program. Added
4167 -C option, equivalent to client's option.
4169 * Added new [ServerKeys] config section to the server. It
4170 configures the server's public and private key.
4172 * Defined generic Public Key Payload into the protocol
4173 specification to send specific type of public keys and
4176 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4177 public key or certificate.
4179 * Implemented the GETKEY command to the server and to the
4180 client library and on user interface.
4182 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Made preliminary `make install' work.
4186 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Added SilcServerRekey context into silcd/idlist.h.
4190 * Added the PFS support as defined in the specification to the
4191 SKE protocol. Affected files lib/silcske/*.c.

4194 the number of the SKE group that is used with PFS in re-key.
4195 Affected file silcd/idlist.h.
4197 * Added PFS re-key support to the server. Affected file is
4200 * Added silc_protocol_cancel to cancel execution of the next
4201 state of the protocol. Affected file is
4202 lib/silccore/silcprotocol.[ch].
4204 * Added the re-key support with and without PFS to the client
4205 library. Re-key is performed once in an hour, by default.
4207 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4208 Added silc_client_rekey_callback and silc_client_rekey_final.
4209 Affected files are lib/silcclient/protocol.[ch] and

4212 * Removed the `hmac_key' and `hmac_key_len' fields from the
4213 SilcClientConnection structure; not needed. Affected file is
4214 lib/silcclient/client.h.
4218 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Do not ask whether user wants to use the negotiated private key
4221 for private messages, just use it. Affected file is
4222 silc/local_command.c.
4224 * Added `send_enc_key' and `enc_key_len' fields to the
4225 SilcIDListData structure since they are needed in the re-key
4226 phase. Affected file is silcd/idlist.[ch].
4228 * Implemented the simple re-key protocol into the server.

4240 the PFS is to be performed in the re-key. Affected file is
4243 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4246 int64 of at least the xintXX size. If void * is less that 4
4247 bytes uint32 * will be used. Defined bool as boolean.
4249 * Changed _ALL_ unsigned long and unsigned int to uint32,
4250 unsgined short to uint16 in the source tree.
4252 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4253 not handle clients that has entry->data.registered == FALSE.
4254 They are not in the network anymore. Affected file is
4257 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Implemented the sending of the SERVER_SIGNOFF notify in the
4260 server. Affected file is silcd/server.c.
4262 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4263 Added also silc_notify_payload_encode_args into the
4264 lib/silccore/silcnotify.[ch].
4266 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4267 Affected file silcd/packet_receive.c.
4269 * Implemented the SERVER_SIGNOFF notify handling in the client
4270 library. Affected file lib/silcclient/client_notify.c. Also,
4271 implemnted the printing of the SERVER_SIGNOFF info to the
4272 application. Affected file silc/client_ops.c.
4274 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4275 if the deleting was successful. Affected file silcd/idlist.[ch].
4277 * Added support for public key authentication in the connection
4278 authentication protocol in the client library. Affected file
4279 lib/silcclient/protocol.c.
4281 * Changed the server's silc_idlist_get_clients_by_* interface
4282 to support already allocated array so that new entries may be
4283 added to pre-allocated array. Affected file silcd/idlist.[ch].
4284 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4285 and command replies.
4287 * All command reply functions in the server now calls the
4288 pending command callback even if error occured. This way the
4289 error will be delivered to the client as well. Affected files
4290 silcd/command.c and silcd/command_reply.c.
4292 * Fixed INFO command to return local server's info if no server
4293 was provided. Affected file lib/silcclient/command.c.
4295 * Removed RESTART command for good. Updated the code and the
4298 * Rewrote parts of the task system. It is a bit simpler now.
4299 Removed unsued task priorities. The affected files are
4300 lib/silcutil/silctask.[ch].
4302 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Moved the USERS printing from the library to the application.
4305 Affected files lib/silcclient/command.c and silc/client_ops.c.
4307 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Added channel key re-key support. The re-key is perfomed
4312 only by the router and is done once in an hour. Added `rekey'
4313 field to the SilcChannelEntry in the server. Affected files
4314 silcd/server.c and silcd/idlist.h.
4316 * Added silc_task_unregister_by_context into the file
4317 lib/silcutil/silctask.[ch].
4319 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Added SILC_UMODE_GONE mode to indicate when the client is not
4322 present in the SILC network. Added also support to the local
4323 command AWAY that will set this mode. Added support of showing
4324 "xxx is gone" in WHOIS command. The USERS command shows the
4325 gone status as well.
4327 * Fixed setting server and router operator privileges in the
4328 server's UMODE command. Affected file silcd/command.c.
4330 * Merged the SKE KE1 and KE2 payloads into one payload. The
4331 new KE payload is equivalent to the old KE2 payload.
4333 Cleaned up the SKE Start Payload parsing. It now uses the
4334 simple buffer unformatting to do the parsing. A lot faster
4337 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4338 to the SKE that is used to indicate whether both of the SKE
4339 parties should perform authentication. By default only the
4340 responder performs authentication. By setting this flag also
4341 the initiator must do authentication. By default it is unset
4342 since in normal SKE case, client to server connection, only
4343 the responder should do authentication. When doing SKE between
4344 two clients both should perform authentication. Updated the
4345 code and the protocol specs.
4347 * A little fix to IDENTIFY command in the server. Search the
4348 client first by hash not nickname. Affected file is
4351 * Fixed the silc_client_close_connection to support closing
4352 the client to client connections wihtout deleting too much
4353 data. Affected file lib/silcclient/client.c.
4355 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4356 are received if protocol used to be active but is not anymore
4357 the application would crash due to NULL pointer dereference.
4358 Affected files silcd/server.c and lib/silcclient/client.c.
4360 * Added `hash' field to the SilcClientConnection to include
4361 the hash function negotiated in the SKE protocol.
4363 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4364 to set the channel founder authentication data. A client can
4365 claim the founder rights later by providing the authentication
4366 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4367 This way the channel founder can regain the channel founder
4368 privileges even it is left the channel. This works only on
4369 local server and the client must be connected to the same
4370 server to be able to regain the founder rights. Updated the
4371 protocol specs accordingly.
4373 Added support to the CMODE command in the client to set the
4374 founder auth data. Read the README to see how to set it.
4376 Added support to the CUMODE command to claim the founder
4377 rights. Read the README to see how to do it.
4379 Added support for the founder authentication to the Channel
4380 Entry in the server. Affected file silcd/idlist.h.
4382 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4383 server's CMODE command. Affected file silcd/command.c.
4385 * Added the following new functions into lib/silccore/silcauth.[ch]:
4386 silc_auth_get_method and silc_auth_get_data.
4388 * The server now saves the remote hosts public key to the
4389 SilcIDListData pointer. Affected file silcd/protocol.c.
4391 * The normal server now does not remove the channel entry from
4392 the cache if the founder authentication data is set. It used
4393 to remove it if the founder was the last one on the channel on
4394 the server and left the channel. The auth data is saved and
4395 if the channel is re-joined later the old entry is used with
4396 the old auth data. Affected files silcd/command_reply.c and
4399 * Removed the `pkcs' field from the SilcIDListData structure
4400 in the server; it is not used. Affected file silcd/idlist.h.
4402 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Fixed packet processing on slow links. Partial packets were
4405 never re-processed because the incoming data buffer was cleared
4406 by the application. Application must not directly clear the
4407 sock->inbuf, the packet processing routines handle it. Fixed
4408 this in client library and in server.
4410 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Fixed the WHOIS and IDENTIFY send reply function to really
4413 check whether to send list or just one entry. Affected file
4416 * Cleaned up the LEAVE command's channel key distribution. The
4417 affected file silcd/command.c.
4419 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4420 can enforce the channel mode as well. In that case the ID
4421 includes the ID of the server. The code now enforces the
4422 mode change if the router have different mode than the server.
4424 * The notify client operation with CMODE_CHANGE notify can now
4425 return NULL client_entry pointer if the CMODE was not changed
4426 by client. Application must check for this.
4428 * Added <Server ID> argument to INFO command to support server
4429 info fetching by Server ID.
4431 * Added silc_server_announce_get_channel_users to get assembled
4432 packets of channel users of the specified channel. Affected
4433 file silcd/server.[ch].
4435 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4436 was freed underneath the ID Cache.
4438 * Re-announce clients when the server received CHANNEL_CHANGE
4439 notify from the router. Affected file silcd/packet_send.c.
4441 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4444 crashed since it did not handle the fact that there is no cipher
4445 called "3" and didn't check the error condition. Now fixed.
4447 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4448 flag. It can be used to send message requests.
4450 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Implemented the RESTART command in the client.
4454 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4455 notice type messages. Added notice printing to the user
4458 * The channel keys are not re-generated if the channel's mode
4459 is PRIVKEY, ie private key on the channel exists. Affected
4460 files silcd/server.c and silcd/command.c.
4462 * Fixed a little bug in channel message delivery when channel
4463 private keys are set in the server. Affected file is
4464 silcd/packet_send.c.
4466 * Changed the setting on channel->on_channel = TRUE from the
4467 silc_client_save_channel_key to the JOIN command reply. The
4468 key payload is not received if the private channel key is set.
4469 Affected file lib/silcclient/command_reply.c and the
4470 lib/silcclient/client_channel.c.
4472 * When the CMODE_CHANGE notify is sent and the channel private
4473 key mode is removed the channel key must be re-generated in
4474 other cells as well. Added this support for the router in the
4475 silcd/packet_receive.c.
4477 * Added new local command NOTICE to send notice message on
4478 channel. Affected file silc/local_command.[ch].
4480 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Added new local command ME to the client. It is used to send
4483 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4484 some action. Affected file silc/local_command.[ch].
4486 * Changed channel_message and private_message client operations
4487 to deliver the message flags to the application. Added also
4488 the `flags' arguments to the silc_client_send_channel_message
4489 and silc_client_send_private_message functions. Affected file
4492 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Redefined the Private Message Payload to support private message
4495 keys and to support the new private message flags. Updated
4496 the protocol specs. Flags makes it possible to have for example
4497 CTCP style messages.
4499 * Added new type SilcPrivateMessagePayload and defined an API
4500 for it in the lib/silcclient/silcprivate.[ch].
4502 * Tested private message private keys successfully. Tested the
4503 private message key set, unset and list commands with the new
4506 * Redefined the Channel Message Payload to include the channel
4507 message flags (equal with private message flags) to support
4508 for example CTCP style messages.
4510 * Defined some of the message (for channel and private message)
4511 flags. Updated the protocol specs and added the flags to the
4512 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4514 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Added SilcKeyAgreementStatus type to the key agreement routines
4517 to indicate the current status and error if one occured.
4518 The status types are defined in the lib/silcclient/silcapi.h.
4520 * Added new local command KEY that is used to set and unset private
4521 keys for channels, set and unset private keys for private messages
4522 with remote clients and to send key agreement requests and
4523 negotiate the key agreement protocol with remote client. The
4524 key agreement is supported only to negotiate private message keys,
4525 it currently cannot be used to negotiate private keys for channels,
4526 as it is not convenient for that purpose.
4528 * Fixed a minor pending callback setting bug in the function
4529 silc_client_get_client_by_id_resolve, now the function works.
4530 Affected file lib/silcclient/idlist.c.
4532 * Added function silc_net_get_local_port to get local bound
4533 port by socket. Added to lib/silcutil/silcnet.[ch].
4535 * Added `sockets' and `sockets_count' fields to the SilcClient
4536 object. They hold the sockets of the listenning sockets in
4537 the client. Listenning sockets may be for example the key
4538 agreement server. Affected file lib/silcclient/client.[ch].
4539 Added functions the silc_client_add_socket and the
4540 silc_client_del_socket. They are exported to the application
4543 * Added ~./silc/clientkeys to support other client's public keys.
4545 * Renamed verify_server_key client operation to verify_public_key
4546 and added one argument to indicate the type of the connection
4547 (server, client etc.).
4549 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Added silc_server_connection_auth_request to handle the
4552 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4553 silcd/packet_receive.[ch].
4555 * Added silc_server_send_connection_auth_request into the
4556 silcd/packet_send.c to send the connection auth request packet.
4558 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4561 * Fixed the public key authentication in responder side in the
4562 server. The `auth_data' pointer includes the SilcPublicKey
4563 not the path to the public key. Affected file silcd/protocol.c.
4565 * Implemented the public key authentication in the initiator side
4566 in the server. Affected file silcd/protocol.c.
4568 * Removed the [RedirectClient] config section from the server
4569 configuration. Is not needed and I don't want to implement it.
4571 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Cleaned up the CMODE command in the server. It now works
4574 correctly and supports all the modes defined in the protocol.
4575 Affected file is silcd/command.c.
4577 * Added `hmac_name' field to the SilcChannelEntry in the server
4578 to hold the default HMAC of the channel. It can be set when
4579 creating the channel (with JOIN command). Affected files
4582 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4583 type to indicate the change of the current cipher and hmac
4584 on the channel. Client can safely ignore the <cipher> argument
4585 (if it chooses to do so) since the CHANNEL_KEY packet will
4586 force the channel key change anyway. The <hmac> argument is
4587 important since the client is responsible of setting the new
4588 HMAC and the hmac key into use.
4590 * Fixed the CMODE command in the client library as well.
4592 * Tested CMODE command in router environment successfully.
4594 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Show the version of the remote client (or server) when connecting
4597 to the server. It is logged to the log file. Affected file
4598 is silcd/protocol.c.
4600 * Fixed the KILLED notify handling in the client library. The
4601 client must be removed from all channels when receiving the
4604 Also, do not remove the client entry when giving the KILL
4605 command but when the KILLED notify is received.
4607 * Removed silc_idlist_find_client_by_nickname from the server.
4608 Not needed anymore. Affected files silcd/idlist.[ch].
4610 * Implemented the CHANNEL_CHANGE notify type handling to the
4611 server. Affected file silcd/server.c.
4615 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Added silc_server_send_notify_invite to send the INVITE
4618 notify between routers.
4620 * Implemented the INVITE command correctly to the server.
4622 * Implemented the INVITE notify type handling in the server.
4624 * Implemented the INVITE command to the client library and on the
4627 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Added function silc_server_get_client_resolve to find the
4630 client entry by ID from all ID lists and then resolve it
4631 (using WHOIS) if it cannot be found. Affected file is
4634 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Implemented the BAN command to the client library.
4638 * The JOIN command in the server now checks the invite list
4641 * Changed the silc_command_reply_payload_encode_va and the
4642 silc_command_payload_encode_va to support that if argument is
4643 NULL it ignores and checks the next argument. Affected file
4644 lib/silccore/silccommand.c.
4646 * Added silc_server_send_notify_ban to send the BAN notify
4647 type between routers.
4649 * Chaned the silc_notify_payload_encode to support that if
4650 argument is NULL it ignores and checks the next argument.
4651 Affected file lib/silccore/silcnotify.c.
4653 * Tested ban lists in router environment successfully.
4655 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Implemented BAN command to the server, in silcd/command.[ch].
4659 * Removed the BAN and INVITE_LIST modes from the CMODE command
4662 * Added function silc_string_match to regex match two strings.
4663 Affected files lib/silcutil/silcutil.[ch].
4665 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Redefined parts of the SilcChannelEntry in the server to support
4668 the new ban and invite lists.
4670 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Redefined the INVITE command. The same command can be used to
4673 invite individuals to the channel but also to manage the invite
4674 list of the channel (to add to and remove from the invite list).
4675 Updated the protocol specs.
4677 * Added new command SILC_COMMAND_BAN that can be used to manage
4678 the ban list of the channel. Updated the protocol specs.
4680 * Removed the channel modes: the SILC_CMODE_BAN and the
4681 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4682 in the CMODE command. The equivalent features are now available
4683 using INVITE and BAN commands. Updated the protocol specs.
4685 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4686 in the network about change in the current ban list. The notify
4687 type is not used by the client.
4689 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4690 support the invite lists.
4692 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Added new function silc_string_regexify that converts string
4695 including wildcard characters into regex string that can
4696 be used by the GNU regex library. Added into the file
4697 lib/silcutil/silcutil.[ch].
4699 Added silc_string_regex_combine to combine to regex strings
4700 into one so that they can be used as one regex string by
4701 the GNU regex library. Added into the file
4702 lib/silcutil/silcutil.[ch].
4704 Added silc_string_regex_match to match two strings. It returns
4705 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4707 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Imported GNU regex to the soruce tree into lib/contrib.
4710 Fixed some compiler warning from the regex.c.
4712 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Fixed MOTD command in the server to work in router environment.
4716 * Fixed the MOTD command in the client library to support
4717 the server argument in the command.
4719 * Added `nickname_len' argument to the silc_idlist_add_client
4720 in the server, as the `nickname' argument may be binary data
4723 * Added silc_idlist_get_channels to return all channels from
4726 * Implemented LIST command to the server. Affected file is
4729 * Implemented the LIST command to the client library and on the
4732 * Added [<user count>] argument to the LIST command reply.
4733 With private channels the user count is not shown.
4735 * Updated TODO and README.
4737 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * The client entry's data.registered must be TRUE even with
4740 global client entry on global client list. The data.registered
4741 is used to check whether the client is anymore in the network,
4742 for example with WHOWAS command so it must be valid.
4744 * Fixed the WHOWAS command in the server. It now actually works
4745 in router environment. Added function into silcd/command_reply.c
4746 silc_server_command_reply_whowas_save.
4748 * Added silc_idlist_purge function to the silcd/idlist.c
4749 to periodically purge the ID Cache.
4751 * Fixed INFO command in the server. It works now in router
4752 environment. Added <server name> argument to the INFO command
4753 reply. Updated the protocol specs.
4755 * Fixed minor bug in silc_idcache_purge to not purge if the
4756 expire value is zero.
4758 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4759 they were buggy because of the WHOWAS information.
4761 * Fixed local command MSG to handle the async resolving of
4762 the remote client properly. It used to fail the first MSG.
4763 Affected file silc/local_command.c.
4765 * Added `data_len' field to SilcIDCache context.
4767 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Update TODO. Todo in commands in the server.
4771 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4774 used by routers as broadcast packet to inform other routers
4775 about the changed user mode.
4777 Implemented the notify handling in the server. Affected file is
4778 silcd/packet_receive.c. Added the function
4779 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4781 * Added new generic Channel Payload and deprecated the New Channel
4782 Payload. The New Channel Payload is now the generic Channel
4785 * Added new argument `mode' to the silc_server_send_new_channel
4786 as it is required in the Channel Payload now.
4788 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4789 and created a new and real SilChannelPayload to represent the
4790 new generic Channel Payload. Implemented the encode/decode
4791 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4793 * Added silc_server_get_client_channel_list to return the list
4794 of channels the client has joined for WHOIS command reply.
4795 Affected file silcd/server.[ch].
4797 * Implemented the channel list sending in the WHOIS command reply
4798 in server and in the client.
4800 Implemented the channel list displaying on the user interface
4801 as well. Affected file silc/client_ops.c.
4803 * Added silc_channel_payload_parse_list to parse list of Channel
4804 Payloads. It returns SilcDList list of SilcChannelPayloads.
4805 Client for example can use this function to parse the list of
4806 channels it receives in the WHOIS command reply. The caller
4807 must free the list by calling silc_channel_payload_list_free.
4808 Affected files lib/silccore/silcchannel.[ch].
4810 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Added one new argument <user mode> to the WHOIS command reply
4813 to return the mode of the user in SILC. Updated the protocol
4816 Implemented it to the server and client.
4818 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Fixed the mode printing on the user interface on joining.
4821 Affected file silc/client_ops.c.
4823 * Implemented the UMODE command and user modes in general to the
4824 client library and to the user interface.
4826 * Implemented the UMODE command to the server.
4828 * The server now sends UNKNOWN_COMMAND error status if client sends
4829 unknown command. Affected file silcd/command.c.
4831 * All server commands now handle the command identifier the right
4832 way when sending the command reply to the client. The client can
4833 use to identify the command replies with the identifier.
4835 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Added silc_server_get_client_route to resolve the route to
4838 the client indicated by the client ID. Affected file is
4841 * Added silc_server_relay_packet as general function to relay
4842 packet to arbitrary destination. This deprecates functions
4843 like _send_private_message_key, _relay_notify etc. Affected
4844 file is silcd/packet_send.[ch].
4846 Removed silc_server_send_key_agreement,
4847 silc_server_send_private_message_key and
4848 silc_server_packet_relay_notify functions from the file
4849 silcd/packet_send.[ch].
4853 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4854 server. Affected file silcd/packet_receive.[ch].
4856 * Implemented the KILL command to the client. Implemented the
4857 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4858 Affected files lib/silcclient/command[_reply].c and
4859 lib/silcclient/client_notify.c. Implemented the KILL notify
4860 printing in the user inteface.
4862 * Fixed a lot silc_parse_nick memory leaks from the client
4863 library in the file lib/silcclient/command.c.
4865 * Changed the silc_server_send_notify_on_channels's `sender'
4866 argument from SilcSocketConnection to SilcClientEntry to
4867 check the sender as entry and not as connection object and not
4868 to send to the client provided as argument. The affected file
4869 is silcd/packet_send.[ch].
4871 * The notify packets that are destined directly to the client used
4872 to not to be processed by the server. Now changed that and the
4873 server processes all notify packets. After relaying the packet
4874 to the client the notify packet is processed in the server.
4876 * The silc_server_free_client_data now checks whether there is
4877 pending outgoing traffic for the client and purges the data to
4878 the network before removing the client entry.
4880 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4883 an client is killed from the SILC Network. Updated the protocol
4886 Added new function silc_server_send_notify_killed to the
4887 silcd/packet_send.[ch].
4889 * Added function silc_server_packet_relay_notify to relay notify
4890 packets that are destined directly to a client. In this case
4891 the server does not process the notify packets but merely relays
4892 it to the client. Affected file silcd/packet_send.[ch].
4894 Added also silc_server_packet_process_relay_notify to check
4895 whereto relay the notify. Affected file is
4896 silcd/packet_receive.[ch].
4898 * Implemented the KILL command to the server.
4902 * Added the backup schema desgined last fall to the protocol
4903 specs for everyone to see. The specification is in the
4904 *-spec-xx.txt draft and the packet type definitions for the
4905 backup routers is in *-pp-xx.txt draft. Thusly, added also
4906 new packet type SILC_PACKET_CELL_ROUTERS.
4908 * A big security problem in the implementation discovered. The
4909 signoff of an client did not cause new channel key generation
4910 which it of course should've done. The channel keys must be
4911 always re-generated when client leaves (or signoffs) the channel.
4912 The silc_server_remove_from_channels funtion now handles
4913 the channel key re-generation.
4915 * Added `sender' argument to the silc_server_send_notify_on_channels
4916 to not to send the client provided as argument. Affected file
4917 silcd/packet_send.[ch].
4919 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Implemented OPER and SILCOPER commands into the server and
4924 * Added silc_auth_verify and silc_auth_verify_data to verify
4925 the authentication directly from the authentication payload.
4926 It supports verifying both passphrase and public key based
4927 authentication. Affected file lib/silccore/silcauth.[ch].
4929 * Added `hash' field to the SilcIDListData structure. It is the
4930 hash negotiated in the SKE protocol. Affected file is
4933 * Slight redesigning of the SilcAuthPayload handling routines.
4934 Do not send SilcPKCS but SilcPublicKey as argument.
4936 * Implemented the public key authentication support to the
4937 serverconfig. The public key is loaded from the provided path
4938 and saved as authentication data to void * pointer. Thus,
4939 changed the unsigned char *auth_data to void *auth_data;
4941 * Fixed SHUTDOWN command to send the reply before the server
4942 is shutdown. :) Affected file silcd/command.c.
4944 * Fixed fatal bug in CONNECT command. The hostname was invalid
4945 memory and server crashed. Affected file silcd/command.c.
4947 * Fixed fatal bug in CLOSE command. The server_entry became
4948 invalid but was referenced later in the command. Affected file
4951 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Fixed fatal bug in failure packet handling. Server ignored
4954 the failure and thus crashed when it came.
4958 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4961 that the command may be executed only once in (about) 2 seconds.
4962 The old SILC_CF_LAG flag is same but allows command bursts up
4963 to five before limiting.
4965 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4966 server code. Various commands now includes the CF_LAG_STRICT
4967 flag to disallow any kind of miss-use of the command.
4969 * Fixed the silc_buffer_unformat to not to allocate any data
4970 if the length of the data is zero. It used to allocate the
4971 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4973 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Changed the format of AdminConnection configuration section
4976 in the server. Added username of the admin to the format.
4977 Affected files silcd/serverconfig.[ch].
4979 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4980 to return admin configuration data by host, username and/or
4983 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Implemented WHOWAS command to the server. Added the functions:
4987 silc_server_command_whowas_parse,
4988 silc_server_command_whowas_send_reply,
4989 silc_server_command_whowas_from_client and
4990 silc_server_command_whowas_from_server
4992 * Added <Client ID> argument to the WHOWAS command reply. Updated
4993 the protocol specs accordingly.
4995 * Implemented WHOWAS command and command_reply to the client
4998 Implemented the WHOWAS printing on the user interface.
5000 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5002 * Added new argument to the WHOWAS command reply, the real name.
5003 It is an optional argument. Updated the protocol specs.
5005 * Added SilcIDCacheDestructor callback that is registered when
5006 the SilcIDCache is allocated. The callback is called when
5007 an cache entry in the ID Cache expires, or is purged from the
5008 cache. Added into lib/silccore/idcache.[ch].
5010 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5011 to destruct the client entries when the cache entry expires.
5012 Other ID Cache's in server and in the client library ignores
5015 * If the ID Cache entry's `expire' field is zero then the entry
5016 never expires. Added boolean `expire' argument to the
5017 silc_idcache_add function in the lib/silccore/idcache.[ch].
5018 If it is TRUE the default expiry value is used.
5020 * Added silc_server_free_client_data_timeout that is registered
5021 when client disconnects. By default for 5 minutes we preserve
5022 the client entry for history - for WHOWAS command.
5024 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added support to the server to enforce that commands are not
5027 executed more than once in 2 seconds. If server receives
5028 commands from client more frequently, timeout is registered
5029 to process the commands. Affected file silcd/command.c.
5030 Added new function silc_server_command_process_timeout.
5032 * Changed NICK_NOTIFY handling in client library to check that
5033 if the client's nickname was changed, so there is no need to
5034 resolve anything from the server.
5036 * Removed error printing from the WHOIS and IDENTIFY commands.
5037 If error occurs then it is ignored silently in the client library.
5038 The application, however, may map the received error to
5039 human readable error string. The application currently maps
5040 the NO_SUCH_NICKNAME error to string.
5042 * Made the command status message public to the application. Moved
5043 them from lib/silcclient/command_reply.c to
5044 lib/silcclient/command_reply.h. The application can map the
5045 received command status to the string with the
5046 silc_client_command_status_message function.
5048 * Added check to the server to check that client's ID is same
5049 as the Source ID in the packet the client sent. They must
5052 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Added dist-bzip hook to the Makefile.am to make bzip2
5055 compressed distributions.
5057 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Server now enforces the maximum length for the nickname and
5060 the channel as protocol specification dictates. 128 bytes for
5061 nickname and 256 bytes for channel name.
5063 * Moved the WHOIS printing to the application. The client libary
5064 does not print out the WHOIS information anymore, the application
5065 must do it. Renamed silc_client_command_reply_whois_print to
5066 the silc_client_command_reply_whois_save.
5068 The client's idle time is also sent to the application now, and
5069 the idle is shown on screen.
5071 * Added silc_client_command_reply_identify_save to save the
5072 received IDENTIFY entries.
5074 * Do not check for channel private keys in message sending and
5075 reception if the channel does not have the PRIVKEY mode set.
5076 Affected file lib/silclient/client_channel.c.
5078 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5081 just surfaced after chaning the JOIN procedure.
5083 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Added silc_client_get_clients_by_list to get client entries
5086 from Client ID list, that is returned for example by JOIN
5087 and USERS command replies. The application should use this
5088 function for example when JOIN command reply is received to
5089 resolve the clients already on the channel (library does not
5090 do that anymore as USERS command reply is not used in the JOIN
5091 procedure anymore). Affected files lib/silcclient/silcapi.h and
5092 lib/silcclient/idlist.c.
5094 * JOIN command reply and USERS command reply returns now SilcBuffer
5095 pointers instead of unsigned char pointers when returning
5096 the client list and mode list.
5098 * Added <Client ID> argument to the JOIN command reply, mainly
5099 for the server to identify for which client the command was
5100 originally sent. Updated protocol specs accordingly.
5102 * Added SilcDlist private_key pointer to the SilcChannelEntry
5103 in the client to support the channel private keys. Affected
5104 file is lib/silcclient/idlist.h.
5106 * Added SilcChannelPrivateKey argument to the function
5107 silc_client_send_channel_message so that application can choose
5108 to use specific private ke if it wants to. If it is not provided,
5109 the normal channel key is used, unless private keys are set.
5110 In this case the first (key that was added first) is used
5111 as the encryption key.
5113 * Implemented the support for channel private key handling.
5114 Implemented the following functions:
5116 silc_client_add_channel_private_key,
5117 silc_client_del_channel_private_keys,
5118 silc_client_del_channel_private_key,
5119 silc_client_list_channel_private_keys and
5120 silc_client_free_channel_private_keys
5122 Affected file lib/silcclient/client_channel.c.
5124 * Added the support for the private keys in the channel message
5125 sending and encryption and in the message reception and
5126 decryption. Affected funtions are
5127 silc_client_send_channel_message and silc_client_channel_message.
5129 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Added SKE's key verify callback to the client library's
5132 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5134 * Removed the statement that server (or router) must send USERS
5135 command reply when joining to the channel so that the client
5136 knows who are on the channel. Instead, the client list and
5137 client's mode list is now sent in the JOIN command reply to the
5138 client who joined channel. This is better solution.
5140 * Added function silc_server_get_users_on_channel and function
5141 silc_server_save_users_on_channel to the silcd/server.[ch].
5143 * Removed function silc_server_command_send_users from the
5146 * Do not show topic on the client library anymore. The topic is
5147 sent in the command reply notify to the application and the
5148 application must show the topic now.
5150 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Added client searching by nickname hash into the IDENTIFY and
5153 WHOIS commands in the server as they were clearly missing from
5154 them. Affected file is silcd/command.c.
5156 * Fixed a bug in private message receiving in the client library.
5157 The remote ID was freed and it wasn't supposed, now it is
5160 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Minor fix to the channel payload; allocate the data area, as it
5163 needs to be of specific length.
5165 * If the key agreement port is zero then the operating
5166 system will define the bound port. Affected files are
5167 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5169 * Added new function silc_channel_payload_decrypt into the file
5170 lib/silccore/silcchannel.[ch].
5172 * Moved the channel message etc, check from silc_packet_decrypt
5173 to applications. The library calls now a generic
5174 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5175 when the packet is either normal or special. This was done to
5176 allow more wide range of checking that was not allowed when
5177 the code was in library. Now applications can do virtually any
5178 checks to the packet and return to the library the decision how
5179 the packet should be processed. Affected files are
5180 lib/silccore/silcpacket.[ch].
5182 Added silc_server_packet_decrypt_check to the server and
5183 silc_client_packet_decrypt_check to the client library.
5185 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5186 to send with specified source and destination information.
5188 * Channel message delivery between routers was broken after the
5189 channel key distribution was fixed earlier. The channel key
5190 was used be to distributed to other routers as well which is not
5191 allowed by the protocol. Now this is fixed and channel keys
5192 really are cell specific and the channel message delivery between
5193 routers comply with the protocol specification.
5195 * Fixed various commands in server to check also the global list
5196 for the channel entry and not just the local list. The affected
5197 file silcd/command.c.
5199 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Added assert()s to buffer formatting and unformatting routines
5202 to assert (if --enable-debug) when error occurs. Affected
5203 file: lib/silcutil/silcbuffmt.c.
5205 * Changed to auto-reconnect to check whether the remote host is
5206 router and register the re-connect timeout if it is. It used
5207 to check that whether we are normal server, but router must do
5208 auto-reconnect with another router as well. Affected file
5211 * Removed the [<key len>] option from CMODE command as the cipher
5212 name decides the key length, nowadays. See the defined ciphers
5213 from the protocol specification.
5215 * Added [<hmac>] option to the CMODE command to define the HMAC
5216 for the channel. Added SILC_CMODE_HMAC channel mode.
5218 * Added [<hmac>] option for the JOIN command so that user can
5219 select which HMAC is used to compute the MACs of the channel
5222 * Added Hmac field to the Channel Message Payload. The integrity
5223 of plaintext channel messages are now protected by computing
5224 MAC of the message and attaching the MAC to the payload. The
5225 MAC is encrypted. Now, it is clear that this causes some
5226 overhead to the size of the packet but rationale for this is that
5227 now the receiver can verify whether the channel message decrypted
5228 correctly and also when private keys are set for the channel the
5229 receiver can decrypt the packet with several keys and check from
5230 the MAC which key decrypted the message correctly.
5232 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5233 lib/silccrypt/silccipher.[ch].
5235 * Added silc_hash_len to return the digest length into the
5236 lib/silcrypt/silchash.[ch].
5238 * Rewrote parts of Silc Channel Payload interface in the
5239 lib/silccore/silcchannel.[ch]. The encode function now also
5240 encrypts the packet and parse function decrypts it.
5242 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Fixed a minor formatting bug in the SKE's key material processing.
5245 It actually might have processed the keys wrong way resulting
5248 * Redefined the mandatory HMAC algorithms and added new algorithms.
5249 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5250 and hmac-md5 truncated to 96 bits. The mandatory is now
5251 hmac-sha1-96. Rest are optional (including the one that used
5252 to be mandatory). Rationale for this is that the truncated HMAC
5253 length is sufficient from security point of view and can actually
5254 make the attack against the HMAC harder. Also, the truncated
5255 HMAC causes less overhead to the packets. See the RFC2104 for
5258 * Added new [hmac] configuration section. The SKE used to use
5259 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5260 is of course wrong. The official names that must be proposed in
5261 the SKE are the ones defined in the protocol specification
5262 (hmac-sha1-96 for example). The user can configure any hmac
5263 using any hash function configured in the [hash] section. At
5264 least, the mandatory must be configured.
5266 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5268 * Added HMAC list to the SKE proposal list. It has now both
5269 hash algorithm list and HMAC list. This makes the protocol
5270 incompatible with previous versions. The SKE now seems to work
5271 the way it is supposed to work, for the first time actually.
5273 * Defined plain Hash algorithms to the protocol specification.
5276 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Implemented support for key agreement packets into the server.
5279 Added functions silc_server_key_agreement and
5280 silc_server_send_key_agreement. Other than these functions,
5281 server has nothing to do with this packet.
5283 * Added support for private message key packets into the server.
5284 Added functions silc_server_private_message_key and
5285 silc_server_send_private_message_key.
5289 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5290 called in the protocol's final callback instead in the END
5291 protocol state. This makes a little more sense and in the same
5292 time in client we can use the same protocol routines for normal
5293 key exchange and to key agreement packet handling as well.
5295 * Added to both client's and server's KE protocol context the
5296 SilcSKEKeyMaterial pointer to save the key material. We will
5297 bring the key material to the protocol's final callback by doing
5298 this. The final callback must free the key material.
5300 * Added SKE's packet_send callback into client's KE protocol
5301 context so that the caller can choose what packet sending function
5302 is used. This way we can use different packet sending when
5303 doing normal SKE when doing key agreement packet handling (in
5304 the key agreement packet handling we do not want to encrypt
5307 * Implemented the responder side of the key agreement routines
5308 in the client. The client can now bind to specified port and
5309 accept incoming key negotiation. The key material is passed
5310 to the application after the protocol is over.
5312 * Implemented the processing of incoming Key Agreement packet
5313 in the client. Added function silc_client_key_agreement to
5316 * Implemented the intiator side of the key agreement routines
5317 in the client. The client can now initiate key agreement with
5318 another remote client. The key material is passed to the
5319 application after the protocol is over.
5321 * Created client_keyagr.c to include all the key agreement
5324 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5325 SILC_TASK_CALLBACK except that it is not static.
5327 * Created client_notify.c and moved the Notify packet handling
5328 from the client.[ch] into that file.
5330 * Created client_prvmsg.c and moved all private message and
5331 private message key routines from the client.[ch] into that file.
5333 * Create client_channel.c and moved all channel message and
5334 channel private key routines from the client.[ch] into that file.
5336 * Changed silc_client_get_client_by_id_resolve to resolve with
5337 WHOIS command instead of IDENTIFY command, in the file
5338 lib/silclient/idlist.c.
5340 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Implemented the SKE's responder side to the Client library.
5344 * When FAILURE is received to the protocol do not trust it
5345 blindly. Register a timeout to wait whether the remote closes
5346 the connection as it should do it, only after that process the
5347 actual failure. This was changed to both client and server.
5349 * Added client_internal.h to include some of the structures
5350 there instead of client.h in lib/silcclient/.
5352 * Added function silc_task_unregister_by_callback to unregister
5353 timeouts by the callback function.
5355 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Some "Incomplete WHOIS info" errors has been appearing on the
5358 log files. Took away the entry->userinfo check from WHOIS
5359 reply sending. The entry->userinfo is now " " if client did not
5360 provide one. I thought this was fixed earlier but something
5361 is wrong still. Let's see if the error still appears.
5363 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Fixed a minor bug in the login when the channel key is
5366 re-generated in the server. It used to generate the key in
5367 wrong order and thus caused problems in the channel traffic.
5369 * Fixed a minor bug in channel key distsribution after
5370 KICK command. The key was not sent to the router even though
5373 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Added silc_ske_process_key_material_data as generic routine
5376 to process any key material as the SILC protocol dictates. The
5377 function is used by the actual SKE library but can be used by
5378 applications as well. This relates to the private message keys
5379 and the channel private keys since they must be processed the
5380 same way the normal SILC session keys. The protocol dictates
5381 this. Affected files: lib/silcske/silcske.[ch].
5383 Added also silc_ske_free_key_material to free the
5384 SilcSKEKeyMaterial structure.
5386 * Defined silc_cipher_set_key function to set the key for
5387 cipher without using the object's method function. The affected
5388 files: lib/silccrypt/silccipher.[ch].
5390 * Implemented silc silc_client_add_private_message_key,
5391 silc_client_add_private_message_key_ske,
5392 silc_client_del_private_message_key,
5393 silc_client_list_private_message_keys and
5394 silc_client_free_private_message_keys functions in the
5397 Added functions silc_client_send_private_message_key to send
5398 the Private Message Key payload and silc_client_private_message_key
5399 to handle incoming Private Message Key payload.
5401 * Added Cipher field to the Private Message Key payload to set
5402 the cipher to be used. If ignored, the default cipher defined
5403 in the SILC protocol (aes-256-cbc) is used.
5405 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Removed lib/silcclient/ops.h file.
5409 Redefined parts of the SILC Client Library API. Created new
5410 file silcapi.h that deprecates the ops.h file and defines the
5411 published Client Library API. Defined also private message key
5412 API and channel private key API into the file.
5414 This is the file that the application must include from the
5415 SILC Client Library. Other files need not be included by
5416 the application anymore.
5418 * Added new key_agreement client operation callback and also
5419 defined the Key Agreement library API for the application.
5421 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5424 is used by clients to request key negotiation between another
5425 client in the SILC network. If the negotiation is started it
5426 is performed using the SKE protocol. The result of the
5427 negotiation, the secret key material, can be used for example
5428 as private message key.
5430 Implemented the Key Agreement payload into the files
5431 lib/silccore/silauth.[ch].
5433 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Redefined ciphers for the SILC protocol. Added some new ciphers
5436 and defined the key lengths for the algorithms. Changed the
5437 code accordingly. The default key length is now 256 bits.
5439 * Fixed SKE key distribution function silc_ske_process_key_material
5440 when the key length is more than 128 bits. The default key
5441 length in SILC is now 256 bits.
5443 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5444 to indicate unsupported algorithm.
5446 * Renamed rijndael.c to aes.c and all functions as well.
5448 * Fixed a long standing channel key setting bug in client library.
5449 Weird that it has never surfaced before.
5451 * Fixed bug in channel deletion. If the entire channel is removed
5452 then it must also delete the references of the channel entry
5453 from the client's channel list as the client's channel entry and
5454 the channel's client entry share same memory.
5456 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * Implemented CONNECT and SHUTDOWN commands in the client.
5460 * Implemented CLOSE command to the client.
5462 * Added the function silc_idlist_find_server_by_name into the
5463 files silcd/idlist.[ch].
5465 Added the function silc_idlist_find_server_by_conn into the
5466 files silcd/idlist.[ch].
5468 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * DIE command was renamed to SHUTDOWN. Updated the both code
5473 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5474 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5476 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5479 * Added function silc_server_create_connection function to create
5480 connection to remote router. My server implementation actually
5481 does not allow router to connect to normal server (it expects
5482 that normal server always initiates the connection to the router)
5483 so the CONNECT command is only good for connecting to another
5486 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5489 or some other client was kicked from the channel.
5491 Implemented the handling of the notify type to both client
5494 Implemented silc_server_send_notify_kicked to send the KICKED
5495 notify. It is used to send it to the server's primary router.
5497 * Implemented the KICK command into server and client.
5499 * Added `query' argument to the silc_idlist_get_client function
5500 to indicate whether to query the client from server or not if
5503 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5504 to indicate that the client is not channel founder.
5508 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Removed the rng context from SilcPacketContext structure and
5511 changed that the packet routine uses the Global RNG API.
5513 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Added support for quit message that client can "leave" on the
5516 channel when it quits the SILC. It is ditributed inside the
5517 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5519 Added silc_server_free_client_data that will take the
5520 signoff message as argument.
5522 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5524 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Updated parts of the protocol specification to keep it up
5529 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5532 payloads in one packet.
5534 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5535 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5536 use now the new List flag.
5538 * Also deprecated the following packet types: REPLACE_ID,
5539 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5541 * Added list support for Notify packet in server.
5543 * Added silc_server_send_notify_channel_change to send the
5544 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5545 the silc_server_send_replace_id.
5547 * Added silc_server_send_notify_nick_change to send the
5548 NICK_CHANGE notify type. Deprecates the function
5549 silc_server_send_replace_id.
5551 * Added silc_server_send_notify_join to send the JOIN notify type.
5552 Deprecates the function silc_server_send_new_channel_user.
5554 * Added silc_server_send_notify_leave to send LEAVE notify type.
5555 Deprecates the function silc_server_send_remove_channel_user.
5557 * Added silc_server_send_notify_cmode and
5558 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5559 types. Deprecates the silc_server_send_set_mode function.
5561 * Added SERVER_SIGNOFF notify type to indicate that server has
5562 quit. This means that all clients on the channel from that
5563 server will drop. This can be also used when netsplit happens.
5565 Deprecated REMOVE_ID packet type since it is not needed anymore
5568 Added silc_server_send_notify_server_signoff to send the
5569 SERVER_SIGNOFF notify type. Deprecates the function
5570 silc_server_send_remove_id.
5572 Added also silc_server_send_notify_signoff to send the
5573 SIGNOFF notify type.
5575 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5576 SILC protocol from this day on. Changed the protocol
5577 specification as well.
5579 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5580 notify type. It is used between routers to notify about
5581 topic changes on a channel.
5583 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5586 * Partly updated the protocol specification to comply with the
5587 changes now made. It is still though a bit outdated.
5589 * The JOIN notify type now takes one extra argument <Channel ID>.
5590 The packet used to be destined to the channel but now the
5591 JOIN type may be sent as list thus it is impossible to
5592 destine it to any specific channel. By adding this argument
5593 it is again possible.
5595 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Added CREDITS file. The CHANGES and CREDITS file will appear
5598 in the distribution as well.
5600 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5603 types in the server's silcd/packet_receive.c.
5605 * Implemented CMODE and CUMODE to work in router environment.
5607 * Fixed minor encoding and decoding buglet from the
5608 lib/silccore/silcmode.c.
5610 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5613 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5615 * Changed all SilcConfigServer* and silc_config_server* to
5616 SilcServerConfig* and silc_server_config*, respectively.
5619 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Associated the ID (client or server ID) to the Authentication
5622 Payload to avoid any possibility of forging. Updated the
5623 protocol specification and the code accordingly.
5625 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * The RSA key length is now save to the RsaKey context in the
5628 key generation process in lib/silccrypt/rsa.c. The key length
5629 is now used to figure out the maximum size of the block allowed
5630 to be encrypted/signed.
5632 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5633 is equivalent to the silc_mp_mp2bin but does not allocate any
5636 * Changed silc_mp_mp2bin API to take length argument. If it is
5637 non-zero then the buffer is allocated that large. If zero, then
5638 the size is approximated using silc_mp_sizeinbase, which however
5641 * Created Global RNG API which is global RNG that application can
5642 initialize. After initializing, any routine anywhere in the
5643 code (including library) can use RNG without allocating a new
5644 RNG object. This was done to allow this sort of use of the
5645 RNG in code that has no chance to allocate RNG object. All
5646 applications currently allocate this and many routines in the
5647 library use this. Affected file lib/silccrypt/silcrng.[ch].
5649 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5650 it to use the Global RNG API.
5652 * Defined Authentication Payload into protocol specification that
5653 is used during SILC session to authenticate entities. It is
5654 used for example by client to authenticate itself to the server
5655 to obtain server operator privileges.
5657 Implemented this payload into the lib/silccore/silcauth.[ch].
5658 Implemented also routines for public key based authentication
5659 as the new protocol specification dictates.
5661 Moved definitions of different authentication methods from
5662 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5664 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5665 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5666 silc_pkcs_verify_with_hash functions into the file
5667 lib/silccrypt/silcpkcs.[ch].
5669 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * The client entry's userinfo pointer must be always valid.
5672 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5673 will fail since it requires the userinfo. Now, the userinfo
5674 is allocated as "" if actual userinfo does not exist. Actually,
5675 it must exist and it is totally Ok to drop client connections
5676 that does not announce the userinfo. However, we will make
5677 this workaround for now.
5679 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5680 to return the remote port by socket.
5682 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5685 SILC_SERVER_PENDING_EXEC and added an new macro
5686 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5687 data or when error occurs while processing the pending command.
5689 Added new argument `destructor' into silc_server_command_pending
5690 and to the SilcServerCommandPending object. This destructor is
5691 now called after calling the pending callback or if error occurs
5692 immediately. If error occurs the actual pending callback won't
5693 be called at all - only the destructor. The destructor may be
5694 NULL if destructor is not needed.
5696 All this applies for client library code as well. Similar
5697 changes were made there as well for the pending commands.
5699 In the client, the application must now allocate the
5700 SilcClientCommandContext with the silc_client_command_alloc
5703 * Added reference counter to the SilcServerCommandContext. Added
5704 function silc_server_command_alloc and silc_server_command_dup
5707 Same type of functions added to the client library for the same
5710 * Removed the cmd_ident from IDListData away since it is now
5711 global for all connections. It is the command identifier used
5712 in command sending and with pending commands. The affected file
5715 * Added reference counter to the SilcSocketConnection objecet to
5716 indicate the usage count of the object. The object won't be
5717 freed untill the reference counter hits zero. Currently only
5718 server uses this, and client ignores it. The client must be
5719 set to use this too later. The affected files are
5720 lib/silccore/silcsockconn.[ch]. Added also the function
5721 silc_socket_dup to increase the reference counter.
5723 This was mainly added because it is possible that the socket
5724 is removed underneath of pending command or other async
5725 operation. Now it won't be free'd and proper DISCONNECTING
5726 flags, etc. can be set to avoid sending data to connection that
5727 is not valid anymore.
5729 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5730 the connection. After that it sets SILC_SET_DISCONNECTED.
5731 It is, however, possible that the socket data is not still freed.
5732 The silc_server_packet_process now checks that data is not
5733 read or written to connection that is DISCONNECTED. The socket
5734 get's freed when the reference counter hits zero.
5736 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Changed the client operation API: channel_message operation's
5739 `sender' is now the client entry of the sender, not the nickname
5740 and the `channel' is the channel entry, not the channel name.
5742 In the private_message operation the `sender' is now also the
5743 client entry of the sender not the nickname.
5745 Affected file is lib/silcclient/ops.h and all applications
5746 using the client operations.
5748 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Moved the calling of ops->connect() from connect_to_server_final
5751 into receive_new_id functin since that is the point when the
5752 client is actually allowed to send traffic to network. The
5753 affected file is lib/silcclient/client.c.
5755 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5758 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5759 (if needs broadcasting) instead of broadcasting the packets one
5760 by one which would make a burst in the network traffic.
5762 * Added `broadcast' argument to the functions in silcd/server.[ch]
5763 silc_server_create_new_channel[_with_id] to indicate whether
5764 to send New Channel packet to primary router.
5766 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * Added new function into the silcd/server.[ch] files:
5769 silc_server_create_new_channel_with_id to create new channel with
5770 already existing Channel ID.
5772 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5773 lib/silccore/silcpacket.h. This packet is used t send list of
5774 Set Mode payloads inside one packet. Server uses this to set
5775 the modes for the channels and clients on those channels, that it
5776 announced to the router when it connected to it. The protocol
5777 specification has been updated accordingly.
5779 * The silc_server_new_channel did not handle the packet coming
5780 from normal server as it normally does not send that. However,
5781 when it announces its channels it does send it. Implemented
5782 the support for that.
5784 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5785 into the file lib/silccore/id.h.
5787 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Fixed memory leaks in the functions silc_idlist_del_client,
5790 silc_idlist_del_channel and silc_idlist_del_server in the file
5791 silcd/idlist.c. All of those leaked like a sieve.
5793 * Fixed some small memory leaks in the client's function
5794 silc_client_notify_by_server.
5796 * Added functions into silcd/server.c: silc_server_announce_clients,
5797 silc_server_announce_channels and silc_server_announce_server.
5798 These functions are used by normal and router server to announce
5799 to its primary router about clients, channels and servers (when
5800 router) that we own. This is done after we've connected to the
5803 These functions effectively implements the following packet types:
5804 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5805 and SILC_PACKET_NEW_ID_LIST.
5807 * Added new functions into the silcd/packet_receive.[ch]:
5808 silc_server_new_id_list, silc_server_new_channel_list and
5809 silc_server_new_channel_user_list to handle the incoming
5810 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5812 * Added support of changing Channel ID in the function
5813 silc_server_replace_id. If the server that announces a channel
5814 to the router already exists in the router (with same name but
5815 with different Channel ID), router is responsible to send
5816 Replace ID packet to the server and force the server to change
5817 the Channel ID to the one router has.
5819 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5820 client that the Channel ID has been changed by the router. The
5821 normal server sends this to the client. Client must start using
5822 the new Channel ID as the channel's ID.
5824 Implemented handling of this new type into lib/silcclient/client.c
5825 into the function silc_client_notify_by_server.
5827 * Added new function silc_idlist_replace_channel_id into the files
5828 silcd/idlist.[ch] to replace the Channel ID.
5830 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Call silc_server_command_identify_check always when processing
5833 the IDENTIFY command in silcd/command.c
5835 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5838 send keepalive packets. The packet can be sent by clients,
5839 servers and routers.
5841 Added function silc_socket_set_heartbeat into the file
5842 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5843 If not set, the heartbeat is not performed. The actual
5844 heartbeat is implemented in the low level socket connection
5845 library. However, application is responsible of actually
5848 Added silc_server_send_heartbeat to send the actual heartbeat
5849 packet into silcd/packet_send.[ch]. Server now performs
5850 keepalive with all connections.
5852 * Added silc_task_get_first function into lib/silcutil/silctask.c
5853 to return the timeout task with shortest timeout. There was a bug
5854 in task unregistration that caused problems. TODO has been
5855 updated to include that task system must be rewritten.
5857 * The client library will now resolve the client information when
5858 receiving JOIN notify from server for client that we know but
5859 have incomplete information.
5861 * Rewrote parts of silc_server_remove_from_channels and
5862 silc_server_remove_from_one_channel as they did not remove the
5863 channel in some circumstances even though they should've.
5865 * Encryption problem encountered in server:
5867 The LEAVE command used to send the Channel Key packet to the
5868 router immediately after generating it. However, the code
5869 had earlier sent Remove Channel user packet but not immediately,
5870 ie. it was put to queue. The order of packets in the router
5871 was that Channel Key packet was first and Remove Channel User
5872 packet was second, even though they were encrypted in the
5873 reverse order. For this reason, MAC check failed. Now, this
5874 is fixed by not sending the Channel Key packet immediately but
5875 putting it to queue. However, this is more fundamental problem:
5876 packets that are in queue should actually not be encrypted
5877 because packets that are sent immediately gets encrypted
5878 actually with wrong IV (and thus MAC check fails). So, packets
5879 that are in queue should be encrypted when they are sent to
5880 the wire and not when they put to the queue.
5882 However, the problem is that the current system has not been
5883 designed to work that way. Instead, the packet is encrypted
5884 as soon as possible and left to the queue. The queue is then
5885 just purged into wire. There won't be any fixes for this
5886 any time soon. So, the current semantic for packet sending
5889 o If you send packet to remote host and do not force the send
5890 (the packet will be in queue) then all subsequent packets to the
5891 same remote host must also be put to the queue. Only after the
5892 queue has been purged is it safe again to force the packet
5895 o If you send all packets immediately then it safe to send
5896 any of subsequent packets through the queue, however, after
5897 the first packet is put to queue then any subsequent packets
5898 must also be put to the queue.
5900 Follow these rules and everything works fine.
5902 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Added new function silc_server_remove_clients_by_server to
5905 remove all client entries from ID list when the server connection
5906 is lost. In this case it is also important to invalidate all
5907 client entires as they hold the invalid server entry. This
5908 fixes fatal bug when server has lost connection and will reconnect
5911 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Made some sanity checks to silc_server_daemonise like to check
5914 whether the requested user and group actually exists.
5916 * Added sanity check to SKE's silc_ske_responder_finish to check
5917 that the public and private key actually is valid.
5919 * Invalidate the client's nickname when receiving Replace ID
5920 packet and the Client ID is being replaced. This means that the
5921 server will query the nickname if someone needs it (client)
5924 * Sort the ID Cache in client library when the ID Cache data
5925 has changed (needs sorting).
5927 * Do not allow for SILC client to create several connections to
5928 several servers. The client does not support windows right now
5929 and generating multiple connections causes weird behaviour.
5931 Irssi-silc client does support windows and can handle several
5932 connections without problems, see: www.irssi.org and SILC plugin.
5934 * Fixed some places where client was added to the IDList. The
5935 rule of thumb is following (in order to get everything right):
5936 If the client is directly connected local client then the
5937 `connection' argument must be set and `router' argument must be
5938 NULL to silc_idlist_add_client function. If the client is not
5939 directly connected client then the `router' argument must
5940 bet set and the `connection' argument must be NULL to the
5941 silc_idlist_add_client function.
5943 * The funtion silc_server_packet_send_local_channel actually did
5944 not check whether the client was locally connected or not. It
5945 does that now. Fixed a bug related to LEAVE command.
5947 * Fixed Remove Channel User payload parsing bug in server's
5948 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5950 * The server's silc_server_save_channel_key now checks also the
5951 global ID list for the channel as it might not be in the local
5952 list. Fixed a bug related to LEAVE command.
5954 * Is this the end of the [<unknown>] buglet that has been lurking
5955 around for a long time? A little for loop fix in server's
5956 silc_server_command_whois_parse that is used by both IDENTIFY
5957 and WHOIS command. At least, this was a clear bug and a cause
5958 of one type of [<unknown>] buglet.
5960 * WHOIS and IDENTIFY commands call the function
5961 silc_server_command_[whois/identify]_check function even if
5962 we are not router server.
5964 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Added --with-gmp configuration option. If set the GMP
5967 is always compiled in the SILC source tree. If not set then
5968 it is checked whether the system has the GMP3 installed. If
5969 it has then the GMP won't be compiled (the system's headers
5970 and library is used), if it doesn't have it then the GMP is
5971 compiled in the SILC source tree.
5973 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Changed RSA private exponent generation to what PKCS #1
5976 suggests. We try to find the smallest possible d by doing
5977 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5978 not security fix but optimization.
5980 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5982 * Added new config entry [Identity] to fork the server and run
5983 it as specific user and group. A patch from Bostik.
5985 * Imported Dotconf configuration library into lib/dotconf.
5986 This will be used to create the SILC configuration files later.
5987 It will appear in the distsribution after this commit.
5989 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * A big code auditing weekend happening. Auditing code for
5992 obvious mistakes, bugs and errors. Also, removing any code
5995 Removed files for being obsolete:
5997 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5998 inline in the file lib/silcutil/silcbuffer.h)
6000 o lib/silcutil/silcbufutil.c (the header has inline versions)
6002 Changed code to fix possible error conditions:
6004 o The buffer formatting routines now check that the destination
6005 buffer really has enough space to add the data. This applies for
6006 both buffer formatting and unformatting
6007 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6008 unformatting was changed to accomodate following rules:
6009 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6010 sent to the function while XXX_*STRING will not allocate or copy
6011 the data into the buffer. Instead it sets the pointer from the
6012 buffer into the pointer sent as argument (XXX_*STRING used to
6013 require that the pointer must be allocated already). This change
6014 makes this whole thing a bit more consistent and more optimized
6015 (note that the data returned in the unformatting with XXX_*STRING
6016 must not be freed now). The routines return now -1 on error.
6018 o Tried to find all code that use buffer_format and buffer_unformat
6019 and added return value checking to prevent formatting and
6020 especially unformatting errors and possible subsequent fatal
6023 o Changed ske->x and ske->KEY to mallocated pointers in
6024 lib/silcske/silcske.h. Fixed possible data and memory leak.
6026 o Added return value checking to all *_parse* functions. Fixed
6027 many memory leaks as well.
6029 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6030 so that buffer overflows would not happen. All code now also
6031 checks the return value as it can fail.
6033 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added reconnection support to server if the normal server looses
6036 its connection to the router (for example if router is rebooted).
6037 The server performs normal reconnection strategy implemented
6038 to the server. Affected file silcd/server.c.
6040 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Added new packet type SILC_PACKET_SET_MODE that is used to
6043 distribute the information about changed modes (for clients,
6044 channels and clients channel modes) to all routers in the
6045 network. Updated the protocol specification accordingly.
6047 Added functions into silcd/packet_send.c and
6048 silcd/packet_receive.c: silc_server_send_set_mode,
6049 silc_server_set_mode.
6051 Added new files silcmode.[ch] into lib/silccore that implements
6052 the encoding and decoding of Set Mode Payload. Added new type
6053 SilcSetModePayload. Moved the definitions of different modes
6054 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6056 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Oops, a little mistake in server's connection authentication
6059 protocol. The protocol is not ended with FAILURE but with
6060 SUCCESS if the authentication is Ok. :) Affected file is
6063 * Implemented NICK_CHANGE notify handling in server in the file
6064 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6065 the local clients on the channel. After the changing nickname
6066 in router environment snhould work and the [<unknown>] nickname
6067 should appear no more.
6069 The silc_server_replace_id function that receives the Replace ID
6070 payload now sends the NICK_CHANGE notify type also in the file
6071 silcd/packet_receive.c
6073 * Changed WHOIS and IDENTIFY command to support the maximum amount
6074 of arguments defined in protocol specs (3328 arguments). This
6075 fixed a bug that caused problems when there were more than three
6078 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Added extra parameter, command identifier, to the
6081 silc_client_send_command so that explicit command identifier
6084 Changed that ID list routines uses specific command identifier
6085 when sending WHOIS/IDENTIFY requests to the server so that they
6086 can be identified when the reply comes back.
6088 Affected files lib/silcclient/command.[ch],
6089 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6091 * Added `sender' argument to silc_server_packet_send_to_channel
6092 to indicaet the sender who originally sent the packet to us
6093 that we are now re-sending. Ignored if NULL. Affected file
6094 silcd/packet_send.[ch].
6096 * Added some server statistics support in silcd/server_internal.h
6097 SilcServerStatistics structure and around the server code. Also
6098 send some nice statistics information when client is connecting
6101 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Fixed channel ID decoding in server's JOIN command reply in
6104 silcd/command_reply.c
6106 * Fixed braodcasting of replace ID payload to not to send it if
6107 we are standalone server in silcd/packet_receive.c.
6109 * Fixed all channel message sending routines to not to send
6110 packets to clients that has router set, since they are routed
6111 separately in the same function earlier. Affects file
6112 silcd/packet_send.c and all channel packet sending functions.
6114 * In USERS reply, res_argv[i] are not allocated, the table
6115 is allocated. Thus changed that free the table, not its
6118 * In server's whois_check and identify_check if the client is
6119 locally connected do not send any WHOIS commands - they are not
6122 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Fixed some minor bugs in client when sending WHOIS command. The
6125 arguments was in wrong order.
6127 * Removed statis function add_to_channel from server in
6128 silcd/command.c that was previously used with the joining but
6131 * Tested USERS command in router environment successfully with two
6132 routers, two servers and two clients.
6134 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Reorganized the USERS command and command reply in client library
6137 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6138 When the command is given by user we register a pending command
6139 callback that will reprocess the command after the reply has been
6140 received from the server. When reprocessing the packet we then
6141 display the information. Thus, the USERS information is displayed
6142 now in the command callback instead of in the command reply
6143 callback. The processing of the command is same as previously
6144 when server has sent the command reply in the JOINing process.
6146 * Added to USERS command in silcd/command_reply.c to join the client,
6147 we didn't use to know about, to the channel after we've created
6148 a client entry for it. Also, for clienet we did know already still
6149 check whether it is on the channel or not and add it if not.
6151 * Removed silc_server_command_join_notify as the function and its
6154 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Changed the client's pending command handling to the same as the
6157 server's pending command handling. It is also now possible to
6158 execute command reply functions from other command reply
6159 function as the function callbacks for commands and command
6160 replies are one and same. The pending commands are not static
6161 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6162 in client connection context. Thus, pending commands are server
6163 connection specific as it is convenient.
6165 Changed the function silc_client_command_pending and
6166 silc_client_command_pending_del and added new function
6167 silc_client_command_pending_check. Removed the
6168 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6171 * Added cmd_ident, current command identifier, to the client
6172 connection context in lib/silcclient/client.h to keep track on
6173 command identifiers used in command sending. Client's command reply
6174 function handling now supports the mandatory command identifiers.
6176 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6177 funtions in client to fully support pending command callbacks.
6179 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6180 as one of the arguments to the application in the command reply
6183 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6184 before first releasing SILC but came back. Now it is removed again
6185 and should come back nomore. The FORWARDED flag was used only
6186 by the JOINing procedure by forwarding the command packet to router.
6187 Now, the JOINing procedure has been changed to more generic (due
6188 to various router environment issues) and FORWARDED is not needed
6189 anymore for anything. The protocol specification is yet to be
6192 Now, removed silc_server_packet_forward from server and the flag
6193 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6195 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Renamed NAMES command to USERS command. The NAMES was named that
6198 due to historical reasons. Now it is renamed. Also, rewrote
6199 parts of the USERS command. The nickname list is not sent anymore
6200 by the server. Only Client ID and mode lists are sent in the USERS
6201 command. Changed this also to the protocol specification.
6203 The client now resolves the names and stuff after it receives
6204 the USERS list from the server when joining to the channel.
6206 * WHOIS and IDENTIFY commands has been changed to support multiple
6207 Client ID's per command. One can now search for multiple users
6208 in the network by sending only one WHOIS or IDENTIFY command.
6209 Changed the code and the protocol specifications.
6211 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6212 uses silc_server_command_whois_parse to parse the request. */
6214 * If normal server, do not parse the WHOIS and IDENTIFY requests
6215 before sending it to the router. Saves some time.
6217 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * Fixed JOIN command on client library. Wrong number of arguments
6220 used to crash the client.
6222 * Added silc_server_channel_has_global function to check whether
6223 channel has global users or not.
6225 * Added silc_server_channel_has_local function to check whether channel
6226 has locally connected clients on the channel.
6228 * The silc_server_remove_from_one_channel now checks whether the
6229 channel has global users or not after given client was removed from
6230 the channel. It also checks whether the channel has local clients
6231 on the channel anymore. If it does not have then the channel entry
6232 is removed as it is not needed anymore.
6234 * The silc_server_notify now checks on JOIN notify whether the joining
6235 client is one of locally connected or global. If it is global then
6236 the channel has now global users on the channel and that is marked
6237 to the channel entry. Also, it now saves the global client to
6238 global list who is joining and JOINs it to the channel. This is
6239 for normal server, that is.
6241 Changed silc_server_send_notify_on_channel,
6242 silc_server_packet_relay_to_channel and
6243 silc_server_packet_send_to_channel check if we are normal server
6244 and client has router set (ie. global client) do not send the
6245 message to that client, as it is already routed to our router.
6247 * Implemented LEAVE notify type handling in silc_server_notify
6250 * Tested LEAVE command in router environment successfully. Tested
6251 with two routers, two servers and two clients.
6255 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6257 * Implemented SIGNOFF notify type handling in silc_server_notify
6260 * silc_server_remove_id now removes the client entry from all channels
6261 it has joined and thusly sends SIGNOFF notify type.
6263 * Rewrote the NAMES list generation in server by removing two excess
6264 loops. The lists are created now inside one loop.
6266 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * silc_server_remove_channel_user checks now also global list
6269 for channel and client.
6271 * silc_server_new_channel_user checks now both local and global
6272 list for channel and client. Fixed a bug in client id decoding.
6273 Used to decode wrong buffer.
6275 * silc_server_channel_message checks now both local and global
6276 list for channel entry.
6278 * Tested channel joining (hence JOIN) in router environment
6279 successfully. Tested with two routers, two servers and two
6282 * Tested channel message sending in router environment successfully.
6284 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Added silc_server_save_channel_key into server.[ch] to save the
6287 received channel key in Channel Key payload processing. It is
6288 also used in JOIN command reply handling.
6290 Equivalent function silc_client_save_channel_key added into
6291 client.[ch] into client library.
6293 * Changed JOIN command reply to send information whether the channel
6294 was created or not (is existing already) and the channel key
6295 payload. Changed protocol specs accordingly.
6297 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6298 the request was sent by ID and not by nickname. Crashed on
6301 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6304 now correctly save the received data.
6306 * silc_server_free_sock_user_data now notifies routers in the
6307 network about entities leaving the network.
6309 At the same time implemented functions silc_server_remove_id
6310 and silc_server_send_remove_id to receive and send REMOVE_ID
6311 packets. The packet is used to notify routers in the network
6312 about leaving entities. The ID removed will become invalid in
6315 * Added function silc_idlist_del_server into server. Removes and
6316 free's server entry from ID list.
6318 * silc_server_private_message function now checks, if we are router,
6319 that the destination ID really is valid ID, naturally.
6321 * In router when NEW_ID packet is received (for new client) the
6322 hash of the Client ID is saved in the ID Cache but the
6323 client->nickname is set to NULL, instead of putting the hash
6326 IDENTIFY command now also checks that client->nickname must be
6327 valid. If it is not if will request the data from the server who
6328 owns the client. Added new function
6329 silc_server_command_identify_check.
6331 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6332 to set the command to already allocated Command Payload.
6334 * Tested private message sending in router environment with two
6335 routers, two servers and two clients. Fixed minor bugs and now
6338 * Fixed segfault from client's NAMES command. Used to crash if
6341 * Forwarded packets must not be routed even if it is not destined
6342 to the receiver. Changed server code comply with this.
6344 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6346 * Added `require_reverse_mapping' boolean value to ServerParams
6347 structure. If TRUE (not default) the server will require that
6348 the connecting host has fully qualified domain name.
6350 If the reverse mapping is not required and hostname could not be
6351 found the IP address is used as hostname.
6353 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Implemented version string checking to both client and server.
6356 The check is incomplete currently due to the abnormal version
6357 strings used in development version of SILC.
6359 * Changed all command functions in server to use the new
6362 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Changed char *data to unsigned char *data in ID Cache system to
6365 support binary data as ID Cache data. Changed code to support
6366 binary data in lib/silccore/idcache.c.
6368 * Renamed silc_server_packet_relay_command_reply to
6369 silc_server_command_reply as it is normal packet receiving
6370 function. Rewrote the function to accept command replys for
6371 servers and not only for clients.
6373 * Mark remote router always as registered server if we are connecting
6374 to it. Otherwise, commands sent by the router to us are ignored.
6376 * All ID List find routines now returns the ID Cache Entry pointer
6377 as well if requested.
6379 * WHOIS command works now in router environment, tested with two
6380 routers, two servers and two clients.
6382 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6383 in router environment (as it is almost equivalent to WHOIS) but
6384 hasn't been tested thoroughly. Added new functions:
6386 silc_server_command_identify_parse
6387 silc_server_command_identify_send_reply
6388 silc_server_command_identify_from_client
6389 silc_server_command_identify_from_server
6391 * Disabled route cache adding because adding two different ID's with
6392 same IP replaces the old cache entry thus giving wrong route.
6393 The entry->router->connection is always the fastest route anyway
6394 so route cache may not be needed. Of course, new routes maybe
6395 established after receiving the ID when the entry->router->connection
6396 might not be anymore the most optimal.
6398 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Add route cache for received ID for fast routing.
6402 * Added silc_server_packet_route to route received packet on router
6403 that is not destined to us.
6405 * Renamed silc_server_get_route to silc_server_route_get.
6407 * Added id_string and id_string_len fields into SilcServer to
6408 include encoded ServerID for fast comparing without excess
6409 encoding of the ID's.
6411 * Cleaned up WHOIS command on server side. Added following static
6414 silc_server_command_whois_parse
6415 silc_server_command_whois_check
6416 silc_server_command_whois_send_reply
6417 silc_server_command_whois_from_client
6418 silc_server_command_whois_from_server
6420 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6421 arguments in command replies. All command functions should be
6422 updated to use this macro.
6424 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Minor typo fixes on command reply handling on server.
6428 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Added silc_server_command_add_to_channel internal routine to add
6431 the client to the channel after router has created the channel and
6432 sent command reply to the server.
6434 * Added generic silc_server_send_command to send any command from
6437 * Use static buffer with ID rendering instead of duplicating data.
6439 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Fixed a channel user mode bug when joining to a channel server gave
6442 everybody channel founder rights, oops.
6444 * We mark ourselves as the router of the incoming server connection
6445 if we are router ourselves. This way we can check in some packet
6446 sending functions whether it is locally connected server. For
6447 incoming router connections we put NULL.
6449 * For router sending packets locally means now always sending the
6450 packet cell wide; to local clients and local servers. For normal
6451 server sending packet locally means sending it to only local
6454 * Fixed the JOIN command to really work in router environment. If the
6455 channel is created it is always created by the router. Router is
6456 also responsible of making the initial joining to the channel,
6457 sending JOIN notify to the sending server and distributing
6458 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6459 does not exist server doesn't do anything else but forward the
6460 command to the router which performs everything.
6462 * Added silc_server_send_channel_key function to send the Channel Key
6465 * Added silc_server_create_channel_key to create new channel key. The
6466 channel key is now re-generated everytime someone joins or leaves
6467 a channel, as protocol dictates. Note: channel->key_len is the
6470 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6473 packet_receive.[ch] to separate packet sending and receiving
6474 routines. The server.[ch] now includes everything else including
6475 actual packet processing (writing and reading data) and other
6478 Renamed silc_server_private_message_send_internal to
6479 silc_server_send_private_message. The routine is still though
6480 used only to relay private messages as server does not send
6481 private messages itself.
6483 Renamed silc_server_new_channel to silc_server_create_new_channel
6484 and added new function sicl_server_new_channel that handles the
6485 incoming New Channel packet. Added also new sending function
6486 silc_server_send_new_channel to send New Channel Payload.
6488 * Added new function silc_server_notify to process incoming notify
6489 packet to the server/router. Server may then relay the notify
6490 to clients if needed.
6492 * Added new function silc_server_new_channel_user to process incoming
6493 New Channel User packet. Router will redistribute the packet and
6494 send JOIN notify to its local clients and locally connected servers
6495 if needed. Normal server will send JOIN notify to its local client
6496 on same channel when received this packet. Added also corresponding
6497 sending function silc_server_send_new_channel_user to sent the
6500 * Added boolean route argument to send_notif_to_channel and
6501 packet_send_to_channel functions to attempt to route the packet
6502 if it is TRUE and send only locally if it is FALSE.
6504 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * silc_server_replace_id now broadcasts the received replace ID
6507 packet if it is not broadcast packet already. The router must
6508 broadcast to inform other routers about changed ID.
6510 * Added backpointer to server's router into SilcServer context in
6511 silcd/server_internal.h.
6513 * Fixed silc_server_packet_broadcast to send correct broadcast
6516 * The channel key is now distributed to the local client as soon
6517 as it is received from the router (in router environment) so that
6518 no other packet may be sent for the channel until client has
6521 * silc_server_remove_channel_user now broadcasts the received
6522 Remove Channel User packet if it is not broadcast packet already.
6523 The router must broadcast to inform other routers about removed
6526 * Added users field into SilcPacketContext that is a reference count
6527 of the context. One can increase the reference count by calling
6528 silc_packet_context_dup which is now changed to just increase the
6529 reference count instead of duplicating the data. The reference
6530 count is decresed by calling silc_packet_context_free that will
6531 free the data after the reference count hits zero.
6533 For now on the packet context and everything allocated into it
6534 (including the raw packet from network) must be freed by calling
6535 the new silc_packet_context_free function. Added also new function
6536 silc_packet_context_alloc that must be used now to allocate the
6537 context. This also means that if a routine is asynchronous from
6538 silc_[client/server]_packet_parse_type the packet context must
6539 be duplicated by calling silc_packet_context_dup. Otherwise it
6540 gets free'd after silc_[client/server]_packet_parse_type returns.
6541 Also, one must remember that if packet is duplicated then its
6542 reference count must be decresed by calling the free function as
6543 many times as it was duplicated.
6545 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6546 from both client and server.
6548 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Made joining to a channel working in router environment.
6552 * Cleaned up JOIN command on server side and create function
6553 silc_server_command_join_channel internal routine to make the
6556 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Changed silc_command_pending list to SilcDList. Also, added
6559 `ident' field to SilcServerCommandPending structure to identify
6560 the reply and to call correct callback.
6562 Added silc_server_command_pending_check function to replace the
6563 corresnponding macro. The silc_command_pending list is not
6566 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6567 to set identifier to previously allocated Command Payload. It
6568 is used to set identifier for command when resending Command
6571 * Added silc_command_payload_encode_payload to encode Command
6572 Payload buffer from SilcCommandPayload structure.
6574 * Added silc_argument_payload_encode_payload to encode Argument
6575 payload buffer from SilcArgumentPayload structure.
6577 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Changed WHOIS command to support router connection on server side.
6580 The whois request is always sent to router unless the server is
6581 standalone server. After server has received the reply from the
6582 router will it send the reply to the client.
6584 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6585 broadcast received broadcast packet. The function is used only
6586 by router. The broadcast packet is always sent to the router's
6589 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6590 render given ID to printable string, for log files for example.
6592 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Made basic router to router connections working. At least they
6595 can now connect to each other but nothing really works the way
6596 they are supposed - yet.
6598 * Added new initiator token to RouterConnection configuration
6599 file in silcd/serverconfig.[ch]. It is used to tell whether we
6600 are the initiator to the remote router or whether we'll expect
6601 the other end to connect.
6603 * Moved registering of listener task to silc_server_init, hence
6604 the server starts listenning as soon as it is run, even if it
6605 does not have connections to other routers. Let's see how well
6608 * Changed default connection retry timeouts for more suitable in
6611 * Removed cipher and such arguments from silc_idlist_add_client
6612 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6613 Added new function silc_idlist_add_data to add the keys and stuff
6616 * Added SilcIDListData structure and added it to SilcClientEntry
6617 and SilcServerEntry as their first field in the structure. This
6618 way we can explicitly cast the ID entries to the SilcIDListData
6619 structure and get common data for the entries. In past, we had
6620 to first check what type of connection it is and then cast it to
6621 correct ID entry type. Now, we can directly cast the opaque
6622 pointer to the SilcIDListData (no matter what ID entry it actually
6623 is) and get the data needed.
6625 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6628 in some circumstances even if threre were timeout tasks, though not
6629 IO tasks, but tasks anyway. Now fixed.
6631 * Defined SilcServerConnection structure to hold connection specific
6632 stuff about directly connected servers and routers. The definition
6633 is currently in silcd/server_internal.h. I thought about having
6634 a bit more important role fro this struct but for now it is used
6635 only when connecting to other server (or router actually).
6637 * Added connecting retry support in server when connecting to
6638 router(s). The retry feature implement exponential backoff
6639 algorithm. Also, added SilcServerParams structure to hold default
6640 parameters for server. For now, it include these retry settings
6641 and are hard coded. After server is moded to be as Silc Server
6642 Library this structure will be more important.
6644 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Changed client librarys channel->clients table to SilcList and
6647 changed code accordingly.
6649 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Changed client's channel table to SilcList and changed code
6652 accordingly. Also changed SilcChannelClientEntry to include back-
6653 pointer to the channel so that client entry can use that structure
6654 as list as well and we have fast cross-reference to the channel.
6655 This change dramatically decreased the complexity of channel
6656 handling with client entry and vice versa (removed one extra
6657 loop when searching for channel entry from many functions).
6659 * Changed server->sim from table to SilcDList and changed code
6662 * NAMES command can now be used from user interface. It will show
6663 the user list on the channel, neatly.
6665 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6666 Code now saves realname of the user if it becomes available.
6668 * Renamed configure.in to configure.in.pre and made ./prepare
6669 script to automatically add correct version string to
6670 configure.in which it creates from configure.in.pre.
6672 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6674 * NAMES command reply now shows users mode with the nickname when
6677 * Moved silc_client_ch[u]mode[_char] functions from
6678 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6679 place sucks, they are utility functions and should be in some
6682 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6684 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6687 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6691 * Added TRQ (efficient deque and list library) into lib/trq. This is
6692 a very good list library that is currently used in the SILC. Defined
6693 SilcList API over the library because I didn't like the API very
6694 much. See lib/trq/silclist.h for the API and examples of how to
6695 use the API. Fixed various places in the code to use the new
6696 SilcList API. The SilcList is meant for lists that has a structure
6697 already defined as a list. It is not suitable to add just some
6698 context to the list (in TRQ, the context is the list actually).
6700 So, I defined SilcDList that can be used for the purpose where
6701 predefined list structure does not exit. This can be used as
6702 such list. Now some context just can be added to the SilcDList.
6703 Currently this list is not used in the SILC just yet, though there
6704 are a lot places where this can replace dynamically allocated
6705 tables and I will fix these places, later, to use SilcDList.
6706 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6707 and use TRQ internally).
6709 Also fixed some annoying warning messages that the original TRQ
6710 code generated. Also minor changes to TRQ's Makefile.in.
6712 * Added support for querying by Client ID to both WHOIS and
6713 IDENTIFY commands into server, as required by the protocol.
6715 * Removed method function pointers from SilcBuffer structure. They
6716 weren't used to anything and just increased the context size for
6717 no good reason. This change also made silc_buffer_alloc and
6718 silc_buffer_free functions inline functions.
6720 * Disabled command flooding detection support until it's fixed so
6721 that it accepts commands in but does not execute them more than once
6724 * Added silc_net_localhost(), to return local hostname, into
6725 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6726 that must be initialized before calling silc_client_init.
6728 * Added new function: silc_server_send_notify_on_channels to send
6729 notify messages to all channels client has joined. It is assured
6730 that the message is sent only once per client.
6732 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6733 lib/silcutil/silcutil.[ch] as silc_format function. The new
6734 function is generic and is used by server as well, not only by
6735 the logging routines.
6737 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6738 the provided version string was not acceptable. Added new function:
6739 silc_ske_check_version into lib/silcske/silcske.h. The function
6740 must be implemented by the application (client or server) and it
6741 does not reside in the SKE library. The function checks the version
6742 string remote end sent.
6744 * Added back pointers (to opaque context and to SilcSocketConnection)
6745 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6747 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6748 duplicate packet context structure.
6750 * Changed `notify' client operation to send same arguments as client
6751 receives from server except for ID's. ID's are mapped to correct
6752 ID entry and that is returned. Also, if channel entry is not sent
6753 by server but the notify is for channel the channel entry is sent
6754 to application (otherwise application doesn't know that it is for
6755 channel (library gets it from packet's Destination ID)).
6757 * Added silc_client_remove_from_channels into client library to
6758 remove a client from all channels it has joined to. Used when
6759 received SIGNOFF notify from server. Added also new function
6760 silc_client_replace_from_channels to replace old ID entry with
6761 new ID entry on all channels. Used when received NICK_CHANGE
6764 * Fixed ID Cache list handling in silc_idlist_get_client in
6765 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6766 to get (or query) client by ID.
6768 * Updated TODO list.
6770 * Added connection authentication status message defined by the
6771 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6772 support for these into the code in client and server side.
6774 * Added generic function silc_client_send_command to send any command
6775 with variable argument list. Application should use this function
6776 to send commands if the command functions provided by the library
6777 does not suite for the application's user interface needs.
6779 * Added new `failure' client operation. Application is notified about
6780 received failure packet if client is executing a protocol. In this
6781 case the protocol's execution has failed.
6783 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6784 is required by the protocol.
6786 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6787 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6790 * Added status flag to SilcSKE object to indicate realtime status
6791 of the SKE protocol.
6793 * Application receives now exactly same command reply arguments as
6794 the library receives from server. However, if ID is received the
6795 corresponding ID entry is returned to the application (eg. Client
6796 ID is mapped to correct SilcClientEntry entry and that is returned).
6797 Changed command_reply client operation due to this change.
6799 * Changed all ID's in commands and in command replys as ID Payloads.
6800 Change affected both client and server side codes.
6802 All ID's sent in SILC network (with execption of ID's in SILC
6803 Packet header) are sent in ID Payload to support variable length
6806 * Server now notifies nick changes and notifies all clients on
6807 the channels about the new nickname (about the new Client ID,
6810 * Implemented CMODE command to change channel modes. Supports all
6811 channel modes defined by the protocol specs except ban and invite
6812 lists. (Also, private channel key mode is supported but support for
6813 setting private channel key in client is missing, thus, this mode
6814 has no effect on client side (except that server requires that the
6815 client uses private channel key and normal channel traffic does not
6818 Also, invite mode works per se, but INVITE command does not work
6819 yet correctly, so you can set channel as invite only channel but
6820 inviting clients to the channel does not work (it is yet to be
6821 thought what's the best way to do it).
6823 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6824 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6825 Implemented CUMODE command to change user's mode on the channel.
6826 Supports all modes defined by the protocol specs.
6828 * Added NAMES command reply to return users modes on the channel.
6830 * Removed unnecessary and slow ciphers from lib/silccrypt.
6832 * Set SO_KEEPALIVE option to connection sockets by default.
6834 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6836 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6837 redefined the Notify Payload into protocol specs.
6839 * Added silc_id_payload_parse_id to get ID directly from raw
6842 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6845 accept searching by Client ID as well.
6847 * Added support for LEAVE and SIGNOFF notify types in client library.
6849 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6850 to parse ID Payload from raw data.
6852 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Added flags parameter into silc_ske_assemble_security_properties
6855 function in lib/silcske/silcske.[ch].
6857 * Changed notify client operation to fit better for notify messages
6858 sent by server. The notify payload received from server is now
6859 passed to the application (after parsing it to SilcNotifyPayload).
6860 It is application's responsibility to retrieve the arguments
6861 from the payload and show the message the way it wants. The message
6862 sent by server is implementation specific.
6864 * Changed public keys to comply with the protocol specification.
6865 Old public keys are not supported anymore and are not compatible.
6867 * Removed nickname from Channel Payload as the latest draft removed
6868 it. The client must resolve the nickname from the NAMES command
6869 reply received when it joined the channel.
6871 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6873 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Fixed some errors in protocol specification drafts.
6877 * Created lib/silccore/silcnotify.c to implement Notify Payload
6878 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6879 generic payloads described by protocol specifications. The file
6880 includes implementations for ID Payload and Argument Payload.
6882 * Changed Command Payload implementation to use the new Argument
6883 Payload. Changed command_xxxx_payload to command_payload_xxxx
6884 to comply with SILC coding conventions.
6886 * Added suppport for Argument Payload handling in Notify Payload
6887 implementation as protocol requires it. Added the new support
6888 into server and client lib as well.
6890 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Added support for multiple nicknames on same channel. [n] is
6893 added locally to the nickname if there are more than one same
6894 nicknames on the channel.
6896 * Server now sends all nicknames that matched WHOIS request.
6897 Client also shows the list received from server.
6899 * Added TOPIC command to client side. User can now set and show
6900 current topic on channel.
6902 * Added MOTD command to client and server. Also, server sends the
6903 motd when client connects to the server.
6905 * Changed version strings to comply ISO 8601.
6907 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Fixed protocol error handling in client library. It should now
6910 cope even if the SKE fails for some reason.
6912 * Made new protocol specification drafts for submitting to IETF.
6914 * Implemented TOPIC command to server in silcd/command.c.
6916 * Added two new notify types into lib/silccore/silcnotify.h:
6917 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6918 notify nickname change and topic setting/change on a channel.
6920 * API change of command_reply operation in client library. The
6921 application gets now the status type received from server as well.
6923 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6927 * Cras fixed and optimized the packet handling even further and
6928 it should work now. Minor change to the prototype of function
6929 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6931 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Added new function into lib/silcutil/silcschedule.[ch]:
6934 silc_schedule_with_fd to select() a specified fd. The function
6935 returns after timeout expires or data arrives or goes. The
6936 function is used by packet routines to wait that all data is
6937 received from network.
6939 * Fixed data reading from network in lib/silccore/silcpacket.c.
6940 The code now assures that all data is read from the fd and then
6941 continues packet processing. This was a bug fix since the code
6942 used to drop some data in some circumstances.
6944 * Added new function into lib/silcclient/client.[ch]:
6945 silc_client_start_key_exchange to start key exchange after
6946 connection has been established to server. The code internally
6947 now uses this funtion but its main purpose was to provide it
6948 for applications that perform their own connecting. After
6949 application has created a connection it merely calls this
6950 function to start the key exchange between client and server.
6951 The library takes care of everything else after that.
6953 Updated also lib/silcclient/README to explain the usage of
6956 * Do not send to application information that connection has
6957 been established. Application gets notified it by connect
6960 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Applied cras's patch to add silc_schedule_one function. The
6963 function runs scheduler once and returns.
6965 * Fixed the scheduler after cras messed it up. The timeout
6966 handling works now as it's supposed to work.
6968 * Added into lib/silccore/ silcnotify.h to include notify
6969 message types support. Changed silc_server_send_notify*
6970 functions, in server.[ch], to support those new notify types.
6971 Added the support for the notify types into client library,
6972 as well. Added new notify client operation into ops.h in
6975 * Changed silc_server_packet_send_to_channel to send normal
6976 packets instead of just channel message packets. The function
6977 is now used to send the notify packets to channels. It is not
6978 used to send channel message packets anymore, as server never
6981 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6982 va_arg()s as it seems to require it nowadays. I guess, if SILC
6983 is compiled with older va_arg() the new code should work anyway.
6985 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * Splitted core library. Core library (lib/silccore) includes
6988 now only SILC protocol specific core (and common) components.
6989 Created new utility library (lib/silcutil) that includes more
6990 generic purpose stuff. The stuff for util library was taken
6991 from the old core library. This was minor and easy split.
6993 * Created SILC Client Library (lib/silcclient) that includes
6994 implementation of the SILC client without user interface. This
6995 was major move from silc/ directory. The code has been changed
6996 so that it is transparent towards the user interface. The
6997 silc/ directory includes now the same user interface as before
6998 and it uses the new client library. Read lib/silcclient/README.
6999 Basicly, the client library performs everything else related
7000 to SILC except user interface handling. Also, configuration
7001 files are considered to be part of user interface and library
7002 does not handle them.
7004 This change also changed a lot of structures, function naming etc.
7005 Most important change was that SilcClientWindow object was
7006 renamed to SilcClientConnection in the client library. Created
7007 also new file lib/silcclient/ops.h. Also added new files
7008 silc/local_command.[ch] and silc/client_ops.[ch].
7010 All these changes were made to make it easier for user interface
7011 designers to create what ever user interface for the SILC client
7014 It is also expected that the server will be moved to lib
7015 directory as well and SILC Server Library will be created;
7016 sometimes in the future.
7018 * Removed Local commands from lib/silccore/silccommand.h as
7019 they are application specific and new client library does not
7020 handle any of those anymore.
7022 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7023 old client implementation in silc/.
7025 * Added support for callback functions in SILC_LOG_* macros.
7026 Application can now set its own callbacks that will be called
7027 instead of using the default functions that will always print
7028 the debug messages to stderr (or stdout). Also, debugging can
7029 now be disabled by setting silc_debug to FALSE and re-enabled by
7030 setting it to TRUE. Note, that logging will still work even
7031 if debugging is disabled.
7033 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7034 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7035 silc_log_reset_debug_callbacks.
7037 * To enable debugging in silc client one must give now -d
7038 option on command line.
7040 * Changed silc_schedule_init to automatically allocate task queues
7041 if they are not allocated before calling it.
7043 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Added GMP 3.1 into math library.
7047 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7050 a channel in SILC network. The packet is used by servers and
7051 routers to notify other routers that user has left a channel.
7052 This little feature was missing until now. Added the feature
7053 to protocol specification as well.
7055 Added functions: silc_server_send_remove_channel_user and
7056 silc_server_remove_channel_user into server.[ch].
7058 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7059 lib/silccore/silcpacket.h. However, they are not implemented
7062 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Fixed joining to a channel and sending channel messages
7065 between server and router. The channel message sending should
7066 now work inside a cell.
7068 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7070 * Fixed the private message sending between server and router.
7071 The private message sending should now work inside a cell.
7073 * Added silc_server_replace_id into server.[ch] to replace
7074 existing ID in the SILC network.
7076 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7077 and silc_idlist_replace_server_id into idlist.[ch] in server.
7079 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7081 * Fixed the server to server connections. Server can again now
7082 connect to router. Router to router connections probably does
7085 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7087 * Added dynamic protocol registering support. Now protocols can
7088 registered and unregistered on the fly. Patch by cras.
7090 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7092 * Added lib/contrib directory to hold routines that some platforms
7093 don't have but are needed by SILC.
7095 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7096 into lin/contrib to provide getopt() and getopt_long() for
7097 those who don't have it.
7099 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Added AWAY command to client. When away message is set and
7102 client receives a private message packet the client automatically
7103 replies to the sender with the away message.
7105 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7106 bug seemed to be the cause of recent problems when compiling
7109 * Added version detection support to SKE protocol specification
7110 and added the new changes to the SKE implementation as well.
7111 There were other minor changes in the SKE protocol as well.
7113 Many changes in lib/silcske/silcske.[ch] and in
7114 lib/silcske/payload.[ch].
7116 * Added ^U functionality, clear input line. Patch from cras.
7118 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Mainly small bugfixes on core library. Fixed some debugging
7121 logging and buffer overflow in silclog.c.
7123 * Updated config.sub and config.guess on the distribution tree.
7125 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Added command lagging support in server. Client may execute
7128 commands now only once in two seconds.
7130 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Optimized packet reception. MAC computation and checking is now
7133 also more optimized. A lot previously duplicated code is now
7134 used as generic by both client and server.
7136 * Fixed key pair generation in clientutil.c
7138 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Added into lib/silccore/silcbufutil.[ch] new function;
7141 silc_buffer_realloc.
7143 * Moved generic packet sending/encryption functions to
7144 lib/silccore/silcpacket.[ch] from client and server. Some
7145 rewriting of the functions.
7147 * Moved all generic packet reception/decryption functions to
7148 lib/silccore/silcpacket.[ch] from client and server. The
7149 packet processing is now much cleaner in both client and server.
7150 These were major changes in both client and server.
7152 * Created many common functions in server to do packet sending.
7153 Previously code were duplicated a lot, this has been removed
7156 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Rewrote major parts of the ID cache system. Don't know
7159 whether it is better now or not but at least the API is more
7162 * Major rewrite on ID cache stuff on client because of the ID
7163 cache API changes. Added idlist.c to client.
7165 * Also major rewrite on ID cache stuff on server as well.
7166 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7167 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7168 in hand, instead they are all put into the ID cache system now.
7169 All server_idlist_* routines uses ID cache now instead of
7170 traversing its own lists (those lists does not exist anymore).
7171 SilcIDList though still exists. Also, SilcXXXEntry's are
7174 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7176 * Finally made the SKE implementation compliant to the protocol
7177 specification. All mp integers are now binary encoded as
7178 opposed being HEX encoded.
7180 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7183 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7184 functions: silc_[encode/decode]_pem. Also added function
7185 silc_encode_pem_file to PEM encode with newlines ('\n') for
7188 * SILC public keys are now encoded either PEM or binary. Same
7189 option is for private keys as well. By default private keys
7190 are binary encoded and public keys PEM encoded. Silly HEX
7191 encoding were removed.
7193 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7194 function to create fingerprints.
7196 * Fixed a bug in SHA1; does not change the original data anymore.
7198 * Partly implemented INFO command on client and server side.
7199 Fixed CLEAR command. Changes to SERVER command; show current
7200 server(s) when giving command without arguments. Added
7201 VERSION command to client.
7203 * Added check to server that unregistered connections cannot
7204 execute commands (unless it is specificly allowed).
7206 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7208 * Fixed screen refresh.
7210 * Fixed channel joining bug from client. On some circumstances
7211 client tried to join to a channel it had already joined.
7213 * Added public key verification process into client's protocol.c.
7214 The client now verifies the public key from user and saves
7215 it into ~./silc/serverkeys/ directory.
7217 Added into: clientutil.[ch]: silc_client_verify_server_key.
7219 * Changed SKE protocol's silc_ske_initiator_finish function
7220 to accept callback function that verifies the received public
7221 key. Removed old silc_ske_verify_public_key function.
7223 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7226 silc_pkcs_private_key[_data]_set.
7228 * Made the password and public authentication more cleaner in
7229 server's protocol.c.
7231 * Removed historic and obsolete protocol `channel_auth' from
7232 both client and server.
7234 * Removed wrong way of sending command status messages from
7235 server to client in server's command.c. The old way violated
7236 protocol specification.
7238 Changes to silccore/silccommand.[ch]: removed
7239 silc_command_encode_status_payload -> not needed anymore,
7240 changed silc_command_encode_payload_va to accept extra
7241 argument on variable argument list. The argument type must
7242 now be provided to the function. Also, added new function:
7243 silc_command_encode_reply_payload_va which is same as
7244 normal command_encode_payload_va except command status type
7245 is provided as extra argument.
7247 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7249 * Added ~./silc directory handling. The directory includes the
7250 public and private keys for the client.
7252 Added silc_client_check_silc_dir, silc_client_create_identifier
7253 and silc_client_load_keys.
7255 * Implemented SILC protocol compliant public key. Added public
7256 and private key saving to and loading from files.
7258 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7259 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7260 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7261 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7262 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7264 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7265 silc_pkcs_load_[public/private]_key.
7267 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Added silc_server_get_route (route.[ch]) to get connection
7270 data for the fastest route for given ID.
7272 * Implemented INVITE command on client and server. The command
7273 were re-defined in the SILC Protocol Specification and the
7274 implementation now complies with the specification.
7276 * Implemented PING command on client and server.
7278 * Implemented NAMES command on client and server. The server side
7279 supports currently only normal server not router server yet.
7280 Some changes to NAMES definition in SILC protocol specification.
7282 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7284 * Implemented LEAVE command on client and server.
7286 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7287 again. This change was made to the protocol as well. Server
7288 should not violate the protocol specification anymore.
7290 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7293 was tested. SOCKS4 was not but should work anyway.
