24 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
25 to avoid collisions with other libraries using same type names
28 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
30 * Added `prefer_ipv6' argument to the functions
31 silc_net_gethostbyname[_async]. If it is TRUE it will return
32 IPv6 address over IPv4. If FALSE IPv4 address is returned
33 even if IPv6 address was found. Affected files
34 lib/silcutil/silcnet.[ch].
36 * Added support silc_net_create_connection[_async] to fallback

50 application does not need to define them. Affected file
51 includes/silcincludes.h.
53 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
54 old name went against naming convention. Applications now
55 include "silcclient.h" instead of "clientlibincludes.h".
56 Removed includes/clientlibincludes.h, it is redundant now.
58 * Renamed includes/version.h to silcversion.h.
60 * Added really preliminary support for OS/2 into the util
61 library. Only thread & mutex API is implemented, others
62 are still to be implemented. Created the lib/silcutil/os2/
63 directory. Created also file includes/silcos2.h.

96 * Added `user_count' to the SilcChannelEntry which now tells the
97 number of users on the channel. The user count is now saved
98 in normal server of global channels as well. Affected files
99 silcd/server.c, idlist.h, packet_receive.c and command.c.
101 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

113 Affected file lib/silcclient/client.c.
115 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
117 * ROBOdoc documented the lib/silcske/silcske.h, and improved
118 the SKE interface a bit.
120 * Fixed padding problem in PKCS#1. The padding was not actually
121 random since the random number generator was used incorrectly.
122 This security bug affects only when encrypting with PKCS#1, and
123 it is not currently used at all in SILC. SILC only use signing
124 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
126 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

192 * Added new configuration options and blocks:
193 keepalive_secs, reconnect_count, reconnect_interval,
194 reconnect_interval_max, reconnect_keep_trying and
195 require_reverser_lookup. Added ConnectionParam block, and
196 implemented the connection parameters when connecting as
197 initiator and when accepting connections as responder.

205 algorithm parts and created new file silcalgs.conf, that
206 is now included from the example_silcd.conf.in.
208 * Optimized the silc_server_connect_to_router_second to take
209 the connection configuration object from the SilcServerConnection
210 object instead of finding it during the connecting phase.
211 Added the configuration object to SilcServerConnection struct.
212 Affected files silcd/server_internal.h, server.c.

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

296 * Fixed the file transfer's key agreement payload to include
297 zero port also if the hostname is NULL because it could not
300 Call file transfer monitor callback now also if error occurs
301 during key agreement protocol.
303 Changed the silc_client_file_send interface to return the
304 SilcClientFileError instead of session id. The session ID
305 is returned into pointer provided as argument.

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

345 become invalid in the callback but it was referenced after
346 the callback returned.
348 Do not allow auto rehashing of hash table during the
349 silc_hash_table_foreach operation, for same reasons as it is
350 not allowed for SilcHashTableList. Affected files are
351 lib/silcutil/silchashtable.[ch].
353 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

374 users list to SilcHashTable. The affected files are
375 lib/silcclient/idlist.[ch].
377 * Fixed a bug in hash table tarversing. While the hash table
378 is traversed with SilcHashTableList the table must not be
379 rehashed. It is now guaranteed that auto rehashable tables
380 are not rehashed while tarversing the list. Also defined that
381 silc_hash_table_rehash must not be called while tarversing
382 the table. Added function silc_hash_table_list_reset that must
383 be called after the tarversing is over. The affected files are
384 lib/silcutil/silchashtable.[ch].
386 * Changed all hash table traversing to call the new
387 silc_hash_table_list_reset in server and in client library.
389 * Added function silc_client_on_channel to return the
390 SilcChannelUser entry if the specified client entry is joined

406 sender's old command identifier was not saved back to the
407 sender's command context, fixed now. The affected file is
410 * Create the key in JOIN command of the router did not return
411 the channel key, added check for this. Affected file is
414 * Fixed a channel ID update bug in JOIN command reply. Do
415 not directly upgrade the ID but call the function
416 silc_idlist_replace_channel_id if the ID was changed.
417 Affected file silcd/command_reply.c.
419 * Fixed memory leaks from command calling if it would fail.
420 Affected file silcd/command.c.

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

565 the client becoming valid after the server becomes back
566 online. Affected file silcd/server_util.c.
568 * Added `sock_error' field into the SilcSocketConnection
569 context. When error occurs during socket operation (read
570 or write) the error is saved. Added also new function
571 silc_socket_get_error to return human readable socket error
572 message. Affected files are lib/silcutil/silcsockconn.[ch],
573 lib/silcutil/unix/silcunixsockconn.c, and
574 lib/silcutil/win32/silcwin32sockconn.c.
576 * The server now prints the socket error message in the
577 signoff for client. Affected file silcd/server.c.
579 * Fixed the `created' channel information sending from router
580 to server in JOIN command. Checks now whether the channel
581 really was created or not and set it according that.
583 Fixed the JOIN command to use the client entry's current
584 ID during the joining procedure instead of the one it sent
585 in the command (it is checked though), since it can change
586 between the packet processing and command processing, and
587 would just case unnecessary pain in the client end. Affected
588 file silcd/command.c.
590 * Fixed a channel key payload sending to use correct channel
591 ID when the server was forced to change the channel's ID by
592 router. Router sent the key payload with the old Channel ID.
593 Affected file silcd/packet_receive.c.
595 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
597 * Call silc_server_save_channel_key only if the key payload
598 was provided in the JOIN command's command reply. Affected
599 file silcd/command_reply.c.
601 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
603 * Fixed silc_mp_sizeinbase to return the value correctly with
604 MPI. Affected file lib/silcmath/mp_mpi.c.
606 * Fixed the stop_server signal to correctly stop the scheduler
607 and gracefully stop the server when SIGTERM or SIGINT signals
608 are received. Affected file silcd/silcd.c.
610 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
612 * Simple handling of TERM and HUP signals. Also added some log
613 flushing call around. Affected file is
616 * Fixed small bugs in silclog.c. Now buffering output will take
617 effect after 10 seconds since startup: This will ensure that
618 no important startup messages are lost. Also output redirection
619 will preserve original format ([Date] [Type] message).
620 Affected file is lib/silcutil/silclog.c.
622 * Added two options to the config file, in the logging section:
623 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
624 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
626 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Do not print the warning about log files not being initialized
629 more than once to avoid excess logging. Affected file is
630 lib/silcutil/silclog.c.
632 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
633 the SIM copying in make install in Makefile.am.pre.
635 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
637 * Rewritten silclog APIs. Globally interesting changes follows:
638 silc_log_set_files() changed to silc_log_set_file().
639 silc_log_set_callbacks() changed to silc_log_set_callback().
640 ROBOdoc documented silclog header file.
641 SilcLogCb now returns bool to wether inihibit the default
642 handler or not (to keep the old behaviour return always TRUE).
643 The new APIs should also fix the problem of the
644 silcd_error.log file that was written in the current directory.
647 Log files streams will remain opened after silc_log_set_file()
648 call, means less CPU usage notably on high traffic servers.
649 File streams are now full buffered, and flushed to the disk
650 every 5 minutes, lesses HD activity and CPU usage.
651 Messages can be redirected, allowing admins to configure
652 one single logfile for all server messages.
653 the silc_log_quick global variable to activate fast-logging.
654 Affected files lib/silcutil/silclog.[ch]
656 * Changed some code to conform new silclog APIs. Affected
657 files are doc/example_silcd.conf.in, silcd/server.c
658 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
661 * Fixed a memory leak that could occur in some situations.
662 Affected file silcd/serverconfig.c.
664 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Added the silc_client_del_client to remove the client from
667 all channels as well. Affected file lib/silcclient/idlist.c.
669 * Fixed the client library to correctly remove the client
670 from all channels when the client entry is being destroyed.
671 Affected file lib/silcclient/client_notify.c, command.c.
673 * Added auto-nicking support to the client library. If the
674 applicatio now sets client->nickname it will be sent to the
675 server after connecting by the library. This way for example
676 SILCNICK (or IRCNICK) environment variables will have effect
677 and always change the nickname automatically to whatever
678 it is wanted. Affected file lib/silcclient/client.[ch].
680 * Renamed silc_server_command_bad_chars to the
681 silc_server_name_bad_chars and moved it to the
682 silcd/server_util.[ch]. Added also new function
683 silc_server_name_modify_bad to return nickname that
684 includes bad characters as new nickname without those
685 bad characters. This check and modify is now used in
686 silc_server_new_client when the username is initially set
687 as nickname, so it must be checked to be valid nickname.
688 Affected file silcd/packet_receive.c.
690 * The nickname length is now taken from the packet for real
691 and not trusted to strlen() since it clearly can return
692 wrong length for nickname including bad characters. This
693 also applies to channel names. Affected file silcd/command.c.
695 * Removed the lib/silcsilm/modules directory. Modules are now
696 compiled into the lib/silcsim. Fixed the copying of the
697 modules to follow symbolic links in Makefile.am.pre.
699 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Fixed silc_string_regexify list creation. Fixes bugs with
702 BAN and INVITE commands in server. The affected file is
703 lib/silcutil/unix/silcunixutil.c.
705 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
707 * Removed the command destructor entirely from the server's
708 command and command reply routines. It is not needed, and
709 its usage was buggy and caused crashes. Affected files are
710 silcd/command[_reply].[ch].
712 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
714 * Cancel protocol and NULL sock->protocol if timeout
715 occurred during protocol. Affected file silcd/server.c.
717 * Cancel protocol timeouts always before calling the final
718 callback, to assure that after final callback is called
719 no other state will be called for the protocol anymore.
720 Affected file silcd/protocol.c.
722 * Print error log if incoming connection configuration could
723 not be found. Affected file silcd/server.c.
725 * Fixed JOIN command to correctly save the founder mode
726 to the client on normal SILC server, when the channel
727 was created by the router. Affected file silcd/command.c.
729 * Fixed LIST command (hopefully) to send correct reply
730 packets. Affected file silcd/command.c.
732 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
734 * The silc_packet_receive_process now returns FALSE if the
735 read data was invalid packet, and TRUE if it was ok.
737 The server now checks that if unauthenticated connection
738 sends data and its processing fails the server will close
739 the connection since it could be a malicious flooder.
741 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
743 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
745 * Make sure the warning about error opening a log file is
746 printed only once and not everytime it fails (produces
747 too much useless log). Affected file lib/silcutil/silclog.c.
749 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
751 * Made the silc_server_daemonise() function more readable.
752 Affected file silcd/server.c.
754 * Pid file is now optional, the user may comment it out from
755 the config file. Removed define SILC_SERVER_PID_FILE, we
756 don't need a default any longer. Affected file
757 configure.in.pre, lib/Makefile.am.pre.
759 * Make some use of the pid file. The server now dies at startup
760 if it detects a valid pid file on his path. The server would
761 die anyway in this circumstance, because of the bind() failure.
762 Affected file silcd/silcd.c.
764 * No longer compiling lib/dotconf.
766 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
768 * Fixed JOIN command parsing not to crash. Affected file
769 lib/silcclient/command.c.
771 * Fied the NICK_CHANGE notify to add the new client entry
772 even it is resolved. This removes an <[unknown]> nick
773 thingy bug in the client. Affected file is
774 lib/silcclient/client_notify.c.
776 * Do not try to allocate 0 bytes (efence does not like it)
777 in lib/silccore/silccomand.c when encoding payload.
779 * Do not take IRCNICK as nickname in Irssi SILC client since
780 it is not possible to set nickname before hand connecting
781 the server (TODO has an entry about adding auto-nicking
784 * Changed the silc_server_command_pending to check whether
785 there already exists an pending entry with the specified
786 command, command identifier and pending callback. This is
787 to fix IDENTIFY and WHOIS related crashes that may register
788 multiple pending commands with same identifier. Affected
789 file silcd/command.c.
791 * Fixed the server to reconnect to the router even if it
792 was already reconnecting and EOF was received. This to
793 fix a possibility that the server wouldn't ever try to
794 auto-reconnect to the router. Affected file silcd/server.c.
796 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Fixed the server's password authentication to use the
799 length of the locally saved password, and not the one
800 sent in the packet. Affected file silcd/protocol.c.
802 * Fixed same password authentication problem in the
803 Authentication Payload handling routines in
804 lib/silccore/silcauth.c.
806 * Yet another password authentication problem fixed with
807 channel password handling in silcd/command.c.
809 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
811 * If first character of string in silc_parse_userfqdn is '@'
812 then do not parse it. Affected file is
813 lib/silcutil/silcutil.c.
815 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
817 * Fixed minor bug in IDENTIFY command reply sending, which
818 caused various weird problems during JOIN when it was
819 resolving names for users. Affected file silcd/command.c.
821 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
823 * Fixed the IDENTIFY command reply sending to chech better valid
824 clients. It was possible to send incomplete list of replies.
825 Affected file silcd/command.c.
827 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Added silc_client_command[s]_[un]register functions now to
830 dynamically register the commands in client library. Removed
831 the static table of commands. This allows the client library
832 to call commands without causing the application to know about
833 what commands library has called.
835 Removed the INFO command reply kludge to detect when the command
836 was called by library. Now library use its own command reply
837 function for INFO command.
839 Added function silc_client_command_call to call a command.
840 Application can use it to call command, not access the structure
843 Now all commands that are sent by the client library (not
844 explicitly sent by application) use own command reply functions.
846 Affected files around lib/silcclient/ and in
847 irssi/src/silc/core/.
849 * Fixed the WHOIS command reply sending to chech better valid
850 clients. It was possible to send incomplete list of replies.
852 Fixed the WHOIS and IDENTIFY to send the request to router
853 if normal server did not do it and did not find any results.
855 Affected file silcd/command.c.
857 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Moved the internal data from SilcClient context into its
860 own file, not accesible to application. Affected files
861 lib/silcclient/client.h and lib/silcclient/client_internal.h,
862 and other files in client library.
864 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Added doc/examples installation target in Makefile.am.pre.
869 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
871 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
872 commands the found client entry will be removed from the
873 cache, after notifying application about the error. Affected
874 file lib/silcclient/command_reply.c.
876 * Changed the /MSG to check for exact nickname user gave, and
877 not let `nick' match `nick@host' if it is only one found. Now,
878 user must type the exact nickname (like nick@host2) even if
879 there are no more than one same nicks found. This is to avoid
880 a possibility of sending nickname to wrong nickname since
881 `nick' could match `nick@host'. Affected file is
882 irssi/src/core/silc-servers.c.
884 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
886 * Do not print "you are now server operator" or similar when
887 giving /away command. Affected files are
888 irssi/src/silc/core/client_ops.c, silc-servers.h.
890 * Made the silc_server_command_pending_error_check to send
891 the same command reply payload it received back to the
892 original sender of the command. This way all arguments
893 that was received by the server will be received by the
894 client too. Affected file silcd/command.c.
896 * Added the silc_idcache_add to return the created cache entry
897 to a pointer. Affected file lib/silccore/silcidcache.[ch].
899 * Add global clients to expire if they are not on any channel.
900 This is because normal server will never know if they signoff
901 if they are not on any channel. The cache expiry will take
902 case of these entries. This is done by normal servers only.
903 The affected files are silcd/command_reply.c,
904 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
906 * If server receives invalid ID notification for WHOIS or
907 IDENTIFY and the ID exists in the lists, it is removed.
908 Affected file silcd/command_reply.c.
910 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
911 in client then client entry that it matches is searched and
912 the nickname is printed on the screen for user. Affected
913 file irssi/src/silc/core/client_ops.c.
915 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
917 * Use cache entry expire time in the LIST command reply to
918 purge old entries from the cache after the LIST command
919 reply has been received. This way we don't have non-existent
920 entries in the cache for too long. Affected file is
921 silcd/command_reply.c.
923 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
925 * If we are normal server, and we've not resolved client info
926 in WHOIS or IDENTIFY from router, and it is global client,
927 we'll check whether it is on some channel. If it is not
928 then we cannot be sure about its validity and will resolve it
929 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
930 file silcd/command.c.
932 * Search channel by name (if possible) rather than by ID
933 in IDENTIFY command's command reply. Affected file is
934 silcd/command_reply.c.
936 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Distribute to the channel passphrase in CMODE_CHANGE notify.
939 Updated specs and implemented it. Affected file silcd/command.c,
940 silcd/packet_send.c and silcd/packet_receive.c.
942 * Implemented the <founder auth> payload handling in the JOIN
943 command. If provided all conditions for channel joining
944 except requirement to provide correct passphrase can be
945 overrided by the channel founder. Updated the protocol specs.
946 Affected file silcd/command.c.
948 Added support for founder auth in JOIN command in client
949 library. Fixed the parsing of the JOIN command now to support
950 all options as they should be. The affected file is
951 lib/silcclient/command.c.
953 * Optimized the WHOIS and IDENTIFY commands to send the request
954 to router only if it includes nicknames or other names. If
955 they include only IDs then check the local cache first before
956 routing. Affected file is silcd/command.c.
958 * Added channels topic announcements. Affected file is
959 silcd/packet_receive.c and silcd/server.c.
961 * Fixed the silc_server_send_notify_topic_set to really destine
962 the packet to channel. Affected file silcd/packet_send.c.
964 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
965 library. Affected file lib/silcclient/client_notify.c.
967 * Added UMODE announcements. Affected file silcd/server.c.
969 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Memory leak fixes in:
973 lib/silcutil/silcsockconn.c
974 lib/silcske/silcske.c
977 lib/silccrypt/silcpkcs.c
978 lib/silccore/silccommand.c
979 lib/silccore/silcidcache.c
984 * ROBOdoc documented the lib/silcske/groups.h file and a
985 bit changed the interface for better.
987 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
989 * Update the client entry context in the ID cache after
990 nick change. Affected file lib/silcclient/command.c.
991 Fixes the CUMODE command when regaining founder privileges,
992 and a little WHOIS problem.
994 * Fixed silc_net_gethostbyname to correctly call the
995 inet_ntop. Affected file lib/silcutil/silcnet.c.
997 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
999 * Added IPv6 support checking to the configure.in.pre, added
1000 also --enable-ipv6 option to override the check. Affected
1001 file configure.in.pre.
1003 * The silc_thread_create now calls the start function
1004 directly if threads support is not compiled in. Removes
1005 ugly #ifdef's from generic code. Affected files are
1006 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1008 * Added silc_net_gethostby[name/addr]_async to asynchronously
1009 resolve. Affected files are lib/silcutil/silcnet.[ch].
1011 * Added support for rendering IPv6 based server, client and
1012 channel IDs. Affected file lib/silcutil/silcutil.c.
1014 * Added support for creating IPv6 based server IDs. Affected
1015 file is silcd/serverid.c.
1017 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1019 * Added silc_net_gethostby[addr/name] into the
1020 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1021 routines. Added silc_net_is_ip[4/6]. Affected file is
1022 lib/silcutil/unix/silcunixnet.c. All routines that take
1023 address as argument now supports both IPv4 and IPv6 addresses.
1025 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1027 * Fixed LIST command reply sending in server. Affected file
1030 * Server now sends the kicker's client ID in the KICK notify
1031 to the kicked client. Affected file silcd/command.c.
1033 * The client library now parses the kickers client ID and
1034 UI displays it. Affected files lib/silcclient/client_notify.c
1035 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1037 * Made all payload parsing function prototypes consistent.
1038 They all take now const unsigned char * and uint32 pair as
1039 the payload data instead of SilcBuffer. Changes all around
1040 the source tree. Other unsigned char* -> const unsigned char*
1041 changes around the tree as well.
1043 * Optimized SFTP client and server packet sending not to
1044 allocate new buffer for each packet but to recycle the
1045 first allocated buffer. Affected files are
1046 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1048 * Optimized the SFTP client to use SilcList instead of
1049 SilcDList for requests, because it is faster. Affected file
1050 is lib/silcsftp/sftp_client.c.
1052 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1053 into lib/silccore/silcid.[ch].
1055 Renamed silcpayload.[ch] into silcargument.[ch].
1057 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * If client entry is deleted with active key agreement
1060 session, abort the session.
1062 The silc_client_abort_key_agreement now calls the completion
1063 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1065 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1068 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Don't use __restrict in older GCC's. Affected file is
1071 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1073 * silc_net_localhost now attempts to reverse lookup the
1074 IP/hostname. Affected file lib/silcutil/silcnet.c.
1076 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1077 command. It can be used to gain founder privileges at
1078 the same time when joining the channel.
1080 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1081 kicker's client ID as well. Updated protocol specs.
1083 Defined that the server must send SILC_COMMAND_IDENTIFY
1084 command reply with error status to client who sent
1085 private message with invalid client ID.
1087 Updated the protocol specification.
1089 * Added silc_server_send_command_reply to send any
1090 command reply. Affected file silcd/packet_send.[ch].
1092 * Added silc_id_payload_encode_data to encode ID payload
1093 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1095 * The server now send IDENTIFY command reply with error
1096 status if client ID in private message is invalid. Affected
1097 file silcd/packet_receive.c.
1099 * Save the server key file with server's IP address in
1100 the filename instead of hostname. The affected file is
1101 irssi/src/silc/core/client_ops.c.
1103 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1108 * Added libtool support for compiling shared objects in
1109 lib/silcsim. Affected file configure.in.pre and
1110 lib/silcsim/Makefile.am. Original patch by cras.
1112 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1114 * Pid file configuration, and server's config file fixes
1115 patch by toma. Updated CREDITS file.
1117 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Fixed silc_client_channel_message to not try to decrypt
1120 the message twice if it resolved the destination client
1121 information. This could cause of dropping one channel
1122 message. Affected file lib/silcclient/client_channel.c.
1124 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1126 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1127 lib/silcclient/client.c. This function is used when the SILC
1128 Client is run under some other scheduler, or event loop or
1129 main loop. On GUI applications, for example this may be
1130 desired to used to run the client under the GUI application's
1131 main loop. Typically the GUI application would register an
1132 idle task that calls this function multiple times in a second
1133 to quickly process the SILC specific data.
1135 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1137 * Fixed silc_server_drop() for dropping the supplementary
1138 groups as well, this could cause a security hole on some
1141 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1146 * Write PID file after dropping privileges. Added -F option
1147 to run server on foreground. A patch by debolaz.
1148 Affected files silcd/server.c, silcd/silcd.c.
1150 * Fixed MOTD to return the MOTD file server name. Affected
1151 file silcd/command.c.
1153 * Added INFO command reply handling to the Irssi SILC Client.
1154 Affected file irssi/src/silc/core/client_ops.c.
1156 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Fixed the silc_idcache_list_* routines to really support
1159 the dynamic list. Fixes a crash. Affected file is
1160 lib/silccore/silcidcache.c.
1162 * Fixed the LIST command reply to really call LIST command's
1163 pending callbacks. Affected file silcd/command_reply.c.
1165 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Update conn->local_entry->nickname after giving NICK
1168 command. Affected file lib/silcclient/command.c.
1170 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1172 * Added the [pid] option to the silcd configuration file
1174 Affected files: serverconfig.[ch] and silcd.c
1176 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Save fingerprint in WHOIS command reply in server.
1179 Affected file silcd/command_reply.c.
1181 * Fixed NICK commands pending callback registration.
1182 Affected file lib/silcclient/command.c.
1184 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1186 * Use ++server->cmd_ident when sending commands in server,
1187 instead of random number. Affected file silcd/command.c.
1189 * Fixed GETKEY command reply to call actually GETKEY pending
1190 command callbacks. Affected file silcd/command_reply.c.
1192 * A bit stricter check for nicknames. Check for same nickname
1193 in NICK command also. Affected file silcd/command.c.
1195 * Do not call INFO command everytime client ID changes, only
1196 during first connecting. Affected file lib/silcclient/client.c.
1198 * Set the new nickname only after successful command reply for
1199 NICK command is returned by server. Affected file
1200 lib/silcclient/command.c.
1202 * Remove nicknames from nicklist during server_signoff notify.
1203 Should fix /NAMES bit more. The affected file is
1204 irssi/src/silc/core/silc-channels.c.
1206 * Added `fingerprint' field to the SilcIDListData in the
1207 silcd/idlist.h to hold the fingerprint of the client's
1210 Send the fingerprint of the client's public key in WHOIS
1213 Affected files silcd/command.c, and silcd/idlist.[ch].
1215 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1216 create fingerprint from given data.
1218 * Show the fingerprint of the client's public key in WHOIS.
1219 Affected files irssi/src/module-formats.[ch] and
1220 irssi/src/silc/core/client_ops.c.
1222 * Format the multiple same nicknames also during JOIN and
1223 NICK_CHANGE notifys. Affected file is
1224 lib/silcclient/client_notify.c.
1226 * Do not print error on screen for invalid private message
1227 payload since it can come if someone is sending private
1228 messages with wrong key. Affected file
1229 lib/silccore/silcprivate.c.
1231 * Fixed multiple concurrent /PING crash. Affected file
1232 lib/silcclient/command.c.
1234 * Changed the wrong ID encoding. All IP addresses must be
1235 in MSB first order in encoded format. They were encoded
1236 wrong and was in LSB format. Affected files are
1237 silcd/serverid.c, lib/silcutil/silcutil.c.
1239 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1241 * Call the `connect' client operation through the scheduler
1242 in case of error. Affected file lib/silcclient/client.c.
1244 * Call the `failure' client operation even if the error
1245 occurred locally during a protocol. Affected file is
1246 lib/silcclient/protocol.c.
1248 * Added support of sending LIST command to router from normal
1249 server. This way normal server can get list of all channels
1250 in the network too. Fixed the channel list sending in the
1251 server too. Affected files are silcd/command.c, and
1252 silcd/command_reply.[ch].
1254 * Added silc_server_update_channels_by_server and
1255 silc_server_remove_channels_by_server. They are used during
1256 disconnection of primary router and in backup router protocol.
1257 Affected file silcd/server_util.[ch], silcd/server.c and
1258 silcd/server_backup.c.
1260 * Fixed channel adding to global list in IDENTIFY command
1261 reply in server. Affected file silcd/command_reply.c.
1263 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * If the incoming packet type is REKEY or REKEY_DONE process
1266 that packet always synchronously. Fixes yet another MAC
1267 failed error on slow (dialup) connections. Affected file
1268 lib/silcclient/client.c and silcd/server.c.
1270 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Call check_version SKE callback for initiator too. Affected
1273 file lib/silcske/silcske.c.
1275 * Implemented fix for security hole found in the SKE that was
1276 fixed in the specification few days back; the initiator's
1277 public key is now added to the HASH value computation.
1278 Added backwards support for the old way of doing it too, for
1279 old clients and old servers. Affected file is
1280 lib/silcske/silcske.c.
1282 * Enabled mutual authentication by default in SKE. If initiator
1283 is not providing mutual authentication the responder will
1284 force it. This will provide the proof of posession of the
1285 private key for responder. The affected files are
1286 lib/silcclient/protocol.c and silcd/protocol.c.
1288 * Do not cache anymore the server's public key during SKE.
1289 We do mutual authentication so the proof of posession of
1290 private key is done, and if the server is authenticated in
1291 conn auth protocol with public key we must have the public
1292 key already. Affected file silcd/protocol.c.
1294 * Added new global debug variable: silc_debug_hexdump. If
1295 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1296 file lib/silcutil/silclog.[ch].
1298 * Fixed compilation warning due to char * -> const char *.
1299 Affected files lib/silcutil/silcnet.h, and
1300 lib/silccore/silcauth.[ch].
1302 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Fixed CMODE command when new channel key was created. If
1305 the creation failed the old key was removed. Next time giving
1306 same command would crash the server since the old key was
1307 freed already. Affected file silcd/command.c.
1309 * Fixed the silc_server_announce_get_channels to not crash
1310 on reconnect. Affected file silcd/server.c.
1312 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Added silc_log_set_debug_string function to set a regex
1315 string to match for debug output. Only the function names,
1316 or filenames matching the given debug string is actually
1317 printed. This way it is possible to filter out those debug
1318 strings that user is not interested in.
1320 Fixed a bug in silc_string_regexify.
1322 Affected files lib/silcutil/silclog.[ch], and
1323 lib/silcutil/unix/silcunixutil.c.
1325 * Changed the -d options in both server and Irssi SILC client
1326 to take the debug string as argument. Affected files
1327 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1329 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1331 * Added silc_hash_babbleprint to create a Bubble Babble
1332 Encoded fingerprint. The encoding is developed by Antti
1333 Huima (draft-huima-babble-01.txt), and it creates human
1334 readable strings out of binary data. Affected file
1335 lib/silccrypt/silchash.[ch].
1337 * Print the babble print now in addition of fingerprint as well
1338 in Irssi SILC client. Affected files are
1339 irssi/src/fe-common/silc/module-formats.[ch],
1340 irssi/src/fe-common/silc/core/client_ops.c.
1342 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Fixed a security problem found in SKE. The initiator's
1345 public key too is now added to the HASH hash value creation
1346 which is signed by the responder to create the SIGN value.
1347 This will prevent anyone in the middle to lie to the responder
1348 about the initiator's public key. If this is done now, the
1349 man in the middle will get caught. Updated the protocol
1352 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Better installation directory handling. Configure module
1355 paths and other paths automatically to example_silc* files
1356 in doc/. A patch by toma.
1358 * Fixed compiler warning from MPI library, and from SILC RNG.
1361 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1362 It can be configured with ./configure. A patch by toma.
1364 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Find correct make to use in prepare-clean. A patch by
1367 toma. Affected file prepare-clean.
1369 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1371 * Added irssi variables use_auto_addr, auto_bind_ip,
1372 auto_bind_port and auto_public_ip.
1374 * Changed the interface for silc_client_send_key_agreement
1375 in lib/silcclient/silcapi.h
1379 irssi/src/silc/core/silc-core.c
1381 lib/silcclient/silcapi.h
1382 irssi/src/silc/core/silc-channels.c
1383 lib/silcclient/client_keyagr.c
1386 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Added silc_pkcs_public_key_compare to compare two
1389 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1391 * Check that the client who set the founder mode on the
1392 channel is the same client that is giving the founder
1393 mode to itself. It is done by comparing the saved public
1394 key (it is saved even in the authentication is passphrase).
1395 Affected file silcd/command.c.
1397 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Do not process packet for disconnected socket connection.
1400 Affected file lib/silccore/silcpacket.c.
1402 * Process the DISCONNECT packet through scheduler in the
1403 client library. Affected file lib/silcclient/client.c.
1405 * Fixed the silc_client_packet_parse to not to increase
1406 the packet sequence number if the conn->sock and the
1407 current socket connection is not same. This can happen
1408 for example during key agreement when the conn includes
1409 multiple socket connections (listeners). Affected file
1410 lib/silcclient/client.c.
1412 * The sender of the file transfer request now provides also
1413 the pointer (listener) for the key exchange protocol. If
1414 the listener cannot be created then it sends empty key
1415 agreement and lets the receiver provide the listener.
1417 Added `local_ip' and `local_port' arguments to the
1418 silc_client_file_send. If they are provided they are used,
1419 if not then it will attempt to find local IP address, if
1420 not found or bind fails then the remote client will provide
1423 Affected files are lib/silcclient/client_ftp.c and
1424 lib/silcclient/silcapi.h.
1426 * Extended the FILE SEND command to support defining the
1427 local IP and port for key exchange listener. They are
1428 optional. Affected file irssi/src/silc/core/silc-servers.c.
1430 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Defined to WHOIS command reply the sending of fingerprint
1433 of the client's public key (if the proof of posession of the
1434 corresponding private key is verified by the server).
1435 Updated to the protocol specification.
1437 * Added support of receiving the client's public key's
1438 fingerprint in command reply in client library. Affected
1439 file is lib/silcclient/command_reply.c, and
1440 lib/silcclient/idlist.[ch].
1442 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Do not send over 128 chars long nickname to the server
1445 in NICK command. Affected file lib/silcclient/command.c.
1447 * Do not send over 256 chars long channel names to the server
1448 in JOIN command. Affected file lib/silcclient/command.c.
1450 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Assure that silc_server_close_connection cannot be called
1453 twice for same socket context. Affected file is
1456 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Send error message to application if opening file for
1459 writing during file transfer fails. Affected file is
1460 lib/silcclient/client_ftp.c.
1462 Remove all file transfer sessions for a client that we're
1463 removing from ID cache.
1465 Affected file is lib/silcclient/client_ftp.c.
1467 * Fixed silc_net_addr2bin to return correct address. Affected
1468 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1470 * Fixed file transfer session removing on signoff notify.
1471 Affected file irssi/src/silc/core/silc-servers.c.
1473 * Added the SilcClientFileError to be returned in the monitor
1474 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1475 Affected file lib/silcclient/silcapi.h.
1477 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Fixed a crash in silc_client_ftp_free_sessions and
1480 silc_client_ftp_session_free_client. Affected file
1481 lib/silcclient/client_ftp.c.
1483 * Added `disabled' field in the SilcChannelEntry in the server
1484 to indicate if the server entry is disabled. Affected file
1485 silcd/idlist.h, silcd/command[_reply].c.
1487 * SILC server adds now /var/run/silcd.pid everytime it is
1488 started. Affected file silcd/silcd.c.
1490 * Added silc_server_packet_send_clients to send a packet to
1491 the provided table of client entries. Affected file
1492 silcd/packet_send.[ch].
1494 * Fixed a crash in client resolving in client_prvmsg.c in
1495 client library. Affected file lib/silcclient/client_prvmsg.c.
1497 * Do not actually remove the client directly from ID cache
1498 during SERVER_SIGNOFF, but invalidate it. This way we
1499 preserve the WHOWAS info for the client. Affected file
1500 silcd/server_util.c.
1502 * Fixed SERVER_SIGNOFF notify handling in the server. The
1503 server is now able to process incoming SERVER_SIGNOFF notify
1504 for a server that it doesn't even know about. It will remove
1505 the clients provided in the notify. Affected file
1506 silcd/packet_receive.c.
1508 * Check for partial packet in data queue after every packet that
1509 was found from the queue. Return and wait for more data if
1510 there is partial data in queue. Affected file is
1511 lib/silccore/silcpacket.c.
1513 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Added SilcClietFileError enum to indicate error in
1516 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1517 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1518 Affected files lib/silcclient/silcapi.h and
1519 lib/silcclient/client_ftp.c.
1521 * Check that newsize in silc_buffer_realloc is larger than
1522 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1524 * Added better monitor of file transfers. It now monitors
1525 key agreement protocol during the file transfer too. Added
1526 error reporting too. Affected files
1527 irssi/src/silc/core/silc-servers.c,
1528 irssi/src/fe-common/silc/module-formats.[ch].
1530 * Wrote a help file for FILE command.
1532 * Added silc_rng_global_get_byte_fast to get not-so-secure
1533 random data as fast as possible. Random data is read from
1534 /dev/urandom if available and from the SILC RNG if not
1535 available. It is used in padding generation. Affected file
1536 lib/silccrypt/silcrng.[ch].
1538 * All packets in client library are now processed synchronously.
1539 Optimized packet processing a lot. Affected file
1540 lib/silcclient/client.c.
1542 * All server connection packets are processing synchronously
1543 now in server, to optimize packet processing. Affected file
1546 * Include files are installed now only in Toolkit distribution
1547 if make install is given. Affected files: all Makefile.am's.
1549 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Assure that silc_client_notify_by_server_resolve does not
1552 resolve the client information multiple times. If it cannot
1553 be found by the first it cannot be found at all. Affected
1554 file lib/silcclient/client_notify.c.
1556 * Fixed WHOWAS command reply calling. Affected file
1557 lib/silcclient/command_reply.c.
1559 * Removed all references to silc_idlist_get_client from the
1560 Irssi SILC client since that call is internal call used by
1561 the library. The Irssi SILC client will use now client
1562 retrieval functions found in silcapi.h.
1564 * Fixed a bug in resolving nickname info before sending
1565 private message. It used freed memory. Affected file
1566 irssi/src/silc/core/silc-servers.c.
1568 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1570 * Assure my_channels statistics cannot go negative in server.
1571 Affected files silcd/server.c, silcd/server_util.c.
1573 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1575 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1577 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Win32 Toolkit changes. Affected files
1580 win32/silc.dsw, win32/libsilc/libsilc.def,

1583 lib/sftp/sftp_fs_memory.c.
1585 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Added silc_net_localip to return local host's IP address.
1588 Affected file lib/silcutil/silcnet.[ch].
1590 * If key exchange or rekey protocol is active for a connection
1591 parse all packets syncronously since there might be packets
1592 in packet queue that we are not able to process without first
1593 processing packets before them. Affected file silcd/server,
1594 lib/silcclient/client.c.
1596 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1597 whether library should continue processing the packet.
1598 Affected file lib/silccore/silcpacket.h.
1600 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1601 SilcSFTPMonitorData to SFTP server to monitor various
1602 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1603 lib/silcsftp/sftp_server.c.
1605 * Added silc_file_size to return file size. Affected file
1606 lib/silcutil/silcutil.[ch].

1609 Added preliminary support for simple client to client one-file
1610 transmission. Affected file lib/silcclient/client_ftp.c,
1611 lib/silccilent/client.[ch].
1613 * Added new local command FILE to the Irssi SILC Client.
1614 It is used to perform the file transfer. It has subcommands
1615 SEND, RECEIVE, SHOW and CLOSE. Affected files
1616 irssi/src/silc/core/client_ops.c,
1617 irssi/src/silc/core/silc-server.[ch].
1619 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1621 * Relay the SILC_PACKET_FTP in the server. Affected files

1626 * Renamed silc_file_read and silc_file_write to functions
1627 silc_file_readfile and silc_file_writefile. Added function
1628 silc_file_open and silc_file_close. Affected files
1629 lib/silcutil/silcutil.[ch].
1631 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * Resolve the client info when received private message or
1634 channel message for a client which nickname we don't know.
1635 Affected files lib/silcclient/client_prvmsg.c and
1636 lib/silcclient/client_channel.c.
1638 * Do not crash in /KEY if client is not connected. Affected
1639 file irssi/src/silc/core/silc-channels.c.
1641 * Added SilcClientStatus field to the SilcClientEntry in the
1642 lib/silcclient/idlist.h.
1644 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1645 is incomplete and is being resolved, it won't be resolved
1648 Make sure also that USERS command reply does not resolve
1649 twice information. Affected file is
1650 lib/silcclient/command_reply.c.
1652 Make sure that silc_client_get_clients_by_list does not
1653 resolve twice same information.
1655 * Check for valid client->id in the silc_server_free_client_data.
1656 Affected file silcd/server.c.
1658 * Fixed /GETKEY nick@server not to crash if the server entry
1659 is not found. Affected file lib/silcclient/command.c.
1661 * Fixed the silc_server_check_cmode_rights to check the
1662 requested modes correctly. Affected file silcd/command.c.
1664 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * Better checks for non-printable chars in nick added.
1667 Affected file silcd/command.c.
1669 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1671 * Call the silc_server_udpate_servers_by_server in the
1672 primary router that comes back online in the backup resuming
1673 protocol. Otherwise it routes packets wrong. Affected file
1674 silcd/server_util.[ch], silcd/server_backup.c.
1676 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1679 lib/silcutil/silcbuffmt.[ch].
1681 * Redefined the SILC packet header to include the padding
1682 length. Affected file lib/silccore/silcpacket.[ch].
1684 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1685 length for maximum padding up to 128 bytes). Affected
1686 file lib/silccore/silcpacket.h.
1688 * Removed all backwards support for old 0.5.x MAC thingies.
1689 The SILC packet header change makes it impossible to be
1690 backwards compatible.
1692 * Send the ENDING packet with timeout in the backup resuming
1693 protocol. This is to assure that all routers has connected
1694 to the primary router. Affected file silcd/server_backup.c.
1696 * Changed the RNG to take the first IV from random data. It
1697 used to take it from zero actually. Changed the RNG also
1698 to use /dev/urandom during session. /dev/random is used
1699 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1701 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Changed the SILC packet header to have the first two bytes
1704 (the packet length) encrypted. Affected files aroung the
1705 code tree, lib/silccore/silcpacket.[ch]. Removed the
1706 SilcPacketCheckDecrypt callback. It is not needed anymore
1707 since the silc_packet_receive_process will determine now
1708 whether the packet is normal or special.
1710 * Implemented the unidirectional MAC keys. Affected files
1711 lib/silcske/silcske.c, silcd/protocol.c and
1712 lib/silcclient/protocol.c.
1714 * Implemented the packet sequence number to the MAC computation.
1715 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1716 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1717 lib/silcclient/protocol.c.
1719 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1721 * Allow backup router to announce servers. All servers
1722 announced by backup router are added to the global list
1723 automatically. Update hte server's socket to our primary
1724 router also when backup router announces a server.
1725 Affected file silcd/packet_receive.c.
1727 * Do not update the client->router in the function
1728 silc_server_udpate_clients_by_server if the client is on
1729 global list. We might fail to find any specific server
1730 for locally connected clients and local cell clients. They
1731 should still use the `from' and not `to' as client->router.
1732 This fixes backup router resuming protocol. Affected file
1733 silcd/server_util.c.
1735 * Decrease channel statistics count only if the channel
1736 deletion worked. Affected files are silcd/server.c and
1737 silcd/server_util.c.
1739 * Added silc_server_update_servers_by_server to update origin
1740 of all server entries. Used during backup router protocol.
1741 Affected files silcd/server_util.[ch], silcd/server.c. and
1742 silcd/backup_router.c.
1744 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1745 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1746 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1747 lib/silccrypt/silchmac.c.
1749 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Assure that router cannot reroute the same channel message
1752 to the sender. Affected file silcd/packet_receive.c.
1754 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Made better checks that the channel message is not sent
1757 to the router it came from. Affected file is
1758 silcd/packet_send.c. Fixed memory leak too.
1760 * Announce informations for incoming router connection, but
1761 only after checking if it is replaced by backup router.
1762 Affected file silcd/packet_receive.c.
1764 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Fixed the backup resuming protocol to work in multiple
1767 router environment. Affected file silcd/server_backup.c.
1769 * Route packet only to one router in the function
1770 silc_server_packet_send_to_channel. Affected file is
1771 silcd/packet_send.c.
1773 * Fixed silc_server_send_notify_dest to set the broadcast
1774 flag. Fixed the silc_server_send_notify_topic to actually
1775 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1776 Affected file silcd/packet_send.c.
1778 * Changed the SFTP Filesystem interface. Changed the
1779 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1780 the filesystem operation function. The SilcSFTPFilesystem
1781 is now a context that is allocated by all filesystem allocation
1782 functions and it already includes the operations structure
1783 and filesystem specific context. It is given as argument
1784 now to the silc_sftp_server_start. This made the interface
1785 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1786 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1788 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Changed the backup router adding and getting interfaces
1791 in the server. The router that will be replaced by the
1792 specified backup router is now sent as argument. Affected
1793 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1796 * Added silc_net_addr2bin_ne to return the binary form of
1797 the IP address in network byte order. Affected files
1798 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1800 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Check for existing server ID in silc_server_new_server
1803 and in silc_server_connect_to_router_final and remove the
1804 old entry if it exists. Affected file silcd/packet_receive.c,
1807 * Send the channel message always to only one router, either
1808 in upstream or downstream. Affected file is
1809 silcd/packet_send.c.
1811 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Wrote the definition of the backup resuming protocol to the
1814 protocol specification.
1816 * Removed one redundant channel key generation from normal
1817 server during joining procedure. Removed one redundant
1818 channel key sending from server to router during joining
1819 procedure. Affected file silcd/command.c.
1821 * Made minor bugfixes to the backup router resuming protocol.
1822 Affected file silcd/server_backup.c, server.c.
1824 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Added --disable-asm configuration option. Affected files
1827 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1830 * Implemented the backup resuming protocol that is used to
1831 resume the primary router position in the cell after the
1832 primary router comes back online. Affected files
1833 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1834 and silcd/server_util.[ch].
1836 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Sleep two (2) seconds after sending QUIT command to server.
1839 Affected file lib/silcclient/command.c.
1841 * Assure that if outgoing data buffer is pending do not force
1842 send any data. Affected file silcd/packet_send.c.
1844 * Assure that if outgoing data buffer is pending do not force
1845 send any data. Affected file lib/silcclient/client.c.
1847 * Implemented the backup router support when the primary router
1848 goes down. The servers and routers can now use the backup
1849 router as new primary router without loosing connectivity.
1851 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1854 in the server to indicate disabled entry. All data read
1855 from the connection will be ignored and no data is sent
1856 for entry that is disabled. Affected files are
1857 silcd/idlist.h, silcd/server.c.
1859 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Created SFTP client and server test programs in the
1862 lib/silcsftp/tests directory.
1864 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Implemented memory filesystem (virtual filesystem) for
1867 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1870 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Implemented the SFTP (SSH File Transfer Protocol) to the
1873 lib/silcsftp. It includes SFTP client and SFTP server
1876 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Moved lib/silccore/silcprotocol.[ch] to the
1879 lib/silcutil library.
1881 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1882 take variable argument list pointer as argument. Affected
1883 file lib/silcutil/silcbuffmt.[ch].
1885 * Added silc_buffer_set function that is used to set data
1886 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1887 Affected file lib/silcutil/silcbuffer.h.
1889 * Changed various routines in the core library to use the new
1890 silc_buffer_set instead of allocating new buffer only for
1893 * Added 64-bit value formatting and unformatting support to the
1894 silc_buffer_[un]format routines. Affected file is
1895 lib/silcutil/silcbuffmt.[ch].
1897 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1898 to includes/bitmove.h.
1900 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * Fixed channel user mode saving in client library. Affected
1903 file lib/silcclient/command[_reply].c.
1905 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Defined the file transfer to the SILC Protocol. Added
1908 new packet type SILC_PACKET_FTP and defined File Transfer
1909 Payload. The mandatory file transfer protocol is SFTP
1910 (SSH File Transfer Protocol). Affected file in addition
1911 of the internet draft is lib/silccore/silcpacket.h.
1913 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1914 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1915 is used as part of backup router protocol when the primary
1916 router of the cell is back online and wishes to resume
1917 the position as primary router.
1919 * Redefined the MAC generation keys in the protocol. The
1920 same key is not used anymore in both direction. Both
1921 direction will now use different keys for sending and
1922 receiving. This fixes a potential security flaw. This
1923 change causes incompatibilities in the protocol.
1925 * Redefined also the MAC computation from the packet.
1926 An packet sequence number is now added to the MAC
1927 computation. This prevents possible replay attacks against
1928 the protocol. This change too causes incompatibilities
1931 Added `sequence' field to the SilcPacketContext to hold
1932 the current sequence number for the packet.
1934 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Added `created' field to the SilcIDListData in the file
1937 silcd/idlist.h to indicate the time when the entry was
1940 * Added `created' field to the SilcChannelEntry too. Affected
1941 file silcd/idlist.h.
1943 * Added `creation_time' aguments to all the announcement functions
1944 in the server. If it is provided then only the entries that
1945 was created after the provided time frame are actually
1946 announced. Affected file silcd/server.[ch].
1948 * The protocol says that the Channel ID's IP address must be
1949 based on the router's IP address. Added check for this in
1950 the silc_server_new_channel when processing incoming New Channel
1951 Payload. Affected file silcd/packet_receive.c.
1953 * Print out the correct version with --version in SILC client.
1954 Affected file irssi/src/silc/core/silc-core.c.
1956 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Fixed WHOWAS command to check for completnes of the client
1959 entry always, not just when the command is coming from client.
1960 Affected file silcd/command.c.
1962 * Added new function silc_server_packet_queue_purge to purge the
1963 outgoing data queue to the network. After the function returns
1964 it is guaranteed that the outgoing packet queue is empty.
1965 Affected file silcd/packet_send.[ch].
1967 * Purge the outgoing packet queue in the rekey protocol's final
1968 callback to assure that all rekey packets go to the network
1969 before quitting the protocol. Affected file silcd/server.c.
1971 * Added silc_client_packet_queue_parse as similar function as
1972 in server to the client library. The affected file is
1973 lib/silcclient/client.c.
1975 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Splitted silcd/server.c and created silcd/server_util.[ch]
1978 for utility functions.
1980 * Added new socket flag SILC_SF_DISABLED to indicate that the
1981 connection is open but nothing can be sent to or received from
1982 the connection. Affected file lib/silcutil/silsockconn.[ch].
1983 The checking for disabled socket is checked in the low level
1984 silc_socket_write and silc_socket_read functions.
1986 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Allow only nicknames and channel names that fits into the
1989 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1991 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * When processing JOIN command reply in server check that if
1994 the channel exists in our global list we'll move it the local
1995 list. Affected file silcd/command_reply.c.
1997 * Fixed the check whether client is joined on the channel already
1998 in JOIN command. Affected file lib/silcclient/command.c.
2000 * Fixed the JOIN command reply to check whether the channel
2001 already exists. Affected file lib/silcclient/command_reply.c.
2003 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Added silc_ske_status_string to map the SKE error numbers
2006 to readable strings. The affected files are
2007 lib/silcske/silcske[_status].[ch].
2009 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Do not show the private channels on the WHOIS channel list
2012 as it is not allowed by the protocol. The affected file is
2015 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Assure that the packet length digged from the actual packet
2018 is something sensible in the silc_packet_decrypt_rest_special
2019 in lib/silccrypt/silcpacket.c.
2021 * Free and NULL the allocated pointer in silc_hmac_alloc if
2022 the HMAC allocation fails. The affected file is
2023 lib/silccrypt/silchmac.c.
2025 * Print the selected security properties to the log files in
2026 the server. Affected file silcd/protocol.c.
2028 * Add SKE's reference counter even if calling the completion
2029 callback manually. Otherwise it goes negative, although it
2030 does not cause any problems. The affected file is
2031 lib/silcske/silcske.c.
2033 * Remove the client entry with short timeout after giving the
2034 KILL command. Affected file lib/silcclient/command.c.
2036 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2037 case all found clients are already disconnected (WHOWAS would
2038 found them) in the server. Affected file silcd/command.c.
2040 * Update the last_receive (time of last data received) to be
2041 updated only when received private or channel message so that
2042 the idle time showed in WHOIS makes more sense.
2044 * Added boolean field `valid' in to the SilcClientEntry in the
2045 client library to indicate whether the entry is valid or not.
2046 This fixes the nickname change bug on channel when changing
2047 the nickname to be same than the old (like nick to Nick) the
2048 nickname formatter doesn't set the new nick anymore to Nick@host.
2049 Affected file lib/silcclient/idlist.[ch].
2051 * Now actually fixed the nickname changing on disconnection.
2052 Added new function silc_change_nick to the Irssi SILC Client.
2053 Affected file irssi/src/silc/core/client_ops.c,
2054 irssi/src/silc/core/silc-nicklist.[ch].
2056 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2058 * Check that the public key exists in the GETKEY command before
2059 trying to encode it. Affected file silcd/command.c.
2061 * Print some notifications on received public keys with GETKEY
2062 command in the Irssi SILC Client. Affected files are
2063 irssi/src/fe-common/silc/module-formats.[ch],
2064 irssi/src/silc/core/client_ops.c.
2066 * Use IDENTIFY command to resolve the server information in the
2067 GETKEY command instead of INFO command. Affected file
2068 lib/silcclient/command.c.
2070 * All command reply functions in the client library now calls
2071 the pending command reply callbacks even if an error has
2072 occurred. The server has done this a long time and now it was
2073 time to move the client library to this as well. Now all
2074 errors can be delivered back to the pending command reply
2075 callbacks if necessary. Affected files are
2076 lib/silcclient/command[_reply].[ch].
2078 * Change the nickname on disconnection back to the username
2079 because in reconnect the server will enforce it to it anyway.
2080 Affected file irssi/src/silc/core/silc-servers.c.
2082 * Fixed a config file parsing bug in the Irssi SILC client.
2083 Affected file irssi/src/silc/core/clientconfig.c.
2085 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2087 * When printing the channel mode on JOIN, verify that the
2088 channel key and channel's HMAC are valid. Affected file
2089 irssi/src/silc/core/client_ops.c.
2091 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2094 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2095 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2097 * Removed channel key rekey task deleting from the function
2098 silc_server_save_channel_key. Affected file silcd/server.c.
2099 Added explicit timeout task context instead that is used to
2100 delete the task if we are registering a new task before the
2101 new task has elapsed.
2103 * When channel key rekey occurs the client library now saves
2104 the old channel key for a short period of time (10 seconds) and
2105 is able to use it in case some is still sending channel
2106 messages encrypted with the old key after the rekey. Affected
2107 file lib/silcclient/[idlist.h|client_channel.c].
2109 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * Added check to the silc_server_new_id_real to not accept
2112 new ID if it is the sender's own ID. Affected file is
2113 silcd/packet_receive.c.
2115 * Assure that we do not announce ourself or the one we've
2116 sending our announcements when we're router and are announcing
2117 servers to our primary router. Affected file silcd/server.c.
2119 * Fixed silc_server_command_identify_check_client to assemble
2120 correct WHOIS packet. It send corrupted WHOIS packet and
2121 caused problem with router to router connections. Affected
2122 file silcd/command.c.
2124 Fixed also silc_server_command_whois_check the same way
2125 as for the IDENTIFY command.
2127 * Added new SilcIDListStatus to the server in the SilcIDListData
2128 structure. The status now includes the current status of
2129 the entry (like registered, resolved etc.). Affected file
2130 silcd/idlist.[ch]. Defined a bunch of different status types
2131 as well. This replaced the old boolean registered field as well.
2133 Added resolve_cmd_ident field to the SilcClientEntry structure
2134 too so that if the entry is for example being resolved so
2135 another command may attach to the same pending command reply
2136 without requiring to resolve the same entry again. This concept
2137 should optimize the WHOIS and the IDENTIFY resolving under
2138 heavy load by taking away unnecessary resolving for entries
2139 that are being resolved already.
2141 Added support for adding multiple pending commands for one
2142 command idenfier. Affected file silcd/command[_reply].[ch].
2144 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2145 before deleting the data. Otherwise the hash table will have
2146 freed data in comparison functions. Affected file is
2147 silcd/command_reply.c.
2149 * Fixed silc_idlist_replace_client_id to add the new entry to
2150 the cache with NULL nickname. Otherwise there will be invalid
2151 memory as the nickname after the nickname is freed. Affected
2152 file silcd/packet_receive.c.
2154 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2155 saved into wrong slots because the previous number of entries
2156 was not taken into account. Affected file silcd/idlist.c.
2157 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2159 * If we are router and we receive JOIN notify to a channel that
2160 does not have any users then notified client is marked as the
2161 channel founder, as it is it. The affected file is
2162 silcd/packet_receive.c
2164 * Added to the extended hash table API's table_del_*ext functions
2165 the destructor as argument too, so that the caller can decide
2166 which destructor to use or whether to use destructor at all.
2167 Affected file lib/silcutil/silchashtable.[ch].
2169 * Fixed ID Cache purging. It actually deleted the entries from
2170 the hash table after the data was freed. The hash table ended
2171 up comparing freed memory. The affected file is
2172 lib/silccore/silcidcache.c.
2174 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Fixed Irssi SILC client's KILL command's HELP syntax.
2178 * The USERS command now resolves the detailed user information
2179 if the userinfo field is missing. Affected file is
2180 lib/silcclient/command_reply.c.
2182 * Do not print error in silc_file_read if the read file does
2183 not exist. Just silently return NULL. Affected file is
2184 lib/silcutil/silcutil.c.
2186 * Fixed the silc_log_output to not wine about NULL filename
2187 and to not create some bogus " " filename. Affected file is
2188 lib/silcutil/silclog.c.
2190 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Fixed various printing bugs on the user interface in the
2193 Irssi SILC Client. Minor changes that were forgotten from
2196 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Fixed the configure.in.pre and the compilation and distribution
2199 environment to support the new autoconf 2.52. That version is
2200 now required to compile the CVS trunk.
2202 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2205 to generally parse user@fqdn format strings. Affected file
2206 lib/silcutil/silcutil.c.
2208 * Added nickname_format and nickname_force_format fields to the
2209 SilcClientParams structure. The first one defines the format
2210 for the nicknames that the library will enforce if the receives
2211 multiple same nicknames. The second one is boolean value and
2212 can be used to force the library to always enforce the format
2213 to the nicknames regardles whether there are multiple nicknames
2214 or not. This configurable formatting was employed to flexibly
2215 support accessing multiple nicknames from the user interface.
2216 The userinterface can now set the nicknames to what ever format
2217 they prefer. Affected file lib/silcclient/silcapi.h.
2219 Added function silc_client_nickname_format to the file
2220 lib/silcclient/idlist.c. It performs the nickname formatting.
2222 Added new field `hostname´ to the SilcClientEntry context.
2223 It holds the hostname of the client. Affected file is
2224 lib/silcclient/idlist.h.
2226 * Irssi SILC Client sets the nicknames in nick@hostn format.
2227 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2228 irssi/src/silc/core/silc-core.c.
2230 The WHOIS printing now also shows both the real nickname and
2231 the formatted nickname so that user knows how to access the
2232 user if there are multiple same nicknames cached. Affected
2233 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2234 printing formatting too to take the hostname now as a separate
2235 argument. The Affected file is
2236 irssi/src/fe-common/silc/modules-formats.[ch].
2238 * Changed the silc_client_get_clients_local to accept the formatted
2239 nickname as argument. It accepts the real nickname too but the
2240 formatted nickname can be used to find the true entry from
2241 multiple entries. Affected file lib/silcclient/silcapi.h and
2242 lib/silcclient/idlist.c.
2244 * Added nickname_format_parse field to the SilcClientParams.
2245 It is a callback function provided by the application to parse
2246 the nickname out of the formatted nickname string. The library
2247 calls it to get the nickname from the formatted string. Since
2248 the application generally knows better the format of the nickname
2249 string it parses it instead of the library, even though library
2250 encodes the formatted string. If the callback function is not
2251 provided then the library will use the string as is. The
2252 affected file is lib/silcclient/silcapi.h.
2254 * All the nickname strings passed to the client library in
2255 commands are now expected to be formatted nickname strings.
2256 If the command does not support the formatted nickname string
2257 it will assume that the sent string is the actual nickname.
2258 Affected file lib/silcclient/command.c.
2260 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Added public key authentication support to OPER and SILCOPER
2263 commands in the client library. Affected file is
2264 lib/silcclient/command.c.
2266 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Changed the get_auth_methdod client operation to be asynchronous.
2269 It can be async if the application resolves the authentication
2270 method from the server during the negotiation. Added new
2271 SilcGetAuthMeth completion callback that the application will
2272 call after resolving the authentication method.
2274 Added function silc_client_request_authentication_method that
2275 the application can use to resolve the authentication method
2276 from the server. Added also SilcConnectionAuthRequest callback
2277 that the library will call after the server has replied. The
2278 application can call this function if it does not know the
2279 current authentication method.
2281 Affected files are lib/silcclient/client.c and
2282 lib/silcclient/silcapi.h.
2284 * The Irssi SILC client now automatically resolves the authentication
2285 method incase any configuration information is not present (and
2286 currently there never is). The affected file is
2287 irssi/src/silc/core/client_ops.c.
2289 * Fixed public key authentication from the client library.
2290 Affected file lib/silcclient/protocol.c. Changed also the
2291 protocol specification about the public key authentication in
2292 the connection authentication protocol. The actual data to be
2293 signed is now computed with a hash function before signing.
2295 * Fixed the public key authentication from the server as well.
2296 Affected file silcd/protocol.c.
2298 * Removed the mlock()'s from the memory allocation routines.
2299 Affected file lib/silcutil/silcmemory.c. The ./configure does
2300 not check anymore for the mlock(). Affected file is
2303 * Fixed USERS command in server to allow the execution of the
2304 command for private and secret channels if the client sending
2305 the command is on the channel. Affected file silcd/command.c.
2307 * Fixed silc_client_get_clients_local to return the clients
2308 count correctly. It could return wrong value. Affected file
2309 lib/silcclient/idlist.c.
2311 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2314 types. The assembler optimizations seemed not to like 64-bit
2315 data types. The assmebler optimizations thus are now enabled
2316 also for BSD systems as opposed to only enable them for Linux.
2318 * Do not check for threads at all on BSD systems. Affected
2319 file configure.in.pre.
2321 * Removed -n and -h options from the Irssi SILC Client since
2322 they are not used in silc.
2324 * Fixed the prime generation to assure that the first digit
2325 of the generated random number is not zero since our conversion
2326 routines does not like number strings that starts with zero
2327 digit. If zero digit is seen the random number is regenerated.
2328 This caused some corrupted RSA keys when the zero first digit
2329 was met. Affected file lib/silcmath/silcprimegen.c.
2331 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2333 * Fixed WIN32 configuration in the ./configure script.
2334 Fixed to include xti.h on environments that has it.
2335 Patches by Carsten Ilchmann and andrew.
2337 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Changed the silc_id_create_client_id to be collision
2340 resistant. It is now assured that there cannot be created
2341 two same client ID's. I suspect that some weird bugs in
2342 the server were actually caused by duplicate Client IDs.
2343 Affected file silcd/serverid.[ch]. A router receiving
2344 new ID now also assures and informs the sending server
2345 if the ID caused collision.
2347 * Changed the silc_id_create_channel_id to also assure that
2348 there are no collisions.
2350 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2352 * Statement about ignoring the Mutual Authentication flag when
2353 performing rekey with PFS was a bit misleading. It is ignored
2354 if it was set in the initial negotiation, it cannot be even
2355 set in the rekey. Fixed in the ke-auth draft. Started the
2356 new versions of the protocol drafts in the doc/.
2358 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed a bug in silc_client_command_identify_save when saving
2361 new channel information. The channel name was no duplicated
2362 and caused crash on exit. Affected file is
2363 lib/silcclient/command_reply.c.
2365 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Fixed the getkey command handling in the server. Send just
2368 empty OK reply to the sender if the key could not be fetched
2369 (but everything else was ok, like the key just was not available).
2370 Changed the public key parameter to optional in the protocol
2371 specs so that empty OK reply can be sent. Affected file
2374 Added a message to Irssi SILC client to tell to user if the
2375 server did not return a public key.
2377 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Fixed a channel key regeneration bug. It registered new
2380 timeout tasks exponentially until all system resources were
2381 used. Affected file silcd/server.c.
2383 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Added the SILC Document generator to the scripts/silcdoc.
2386 It can be used to generate the Toolkit Reference Manual out
2387 of the source tree. Internally it will also use the RoboDoc
2388 generator now imported in util/robodoc.
2390 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Added couple of return's in rekey protocol if error orccurred
2393 during the protocol. The execution must be terminated.
2394 Affected file silcd/protocol.c. Also, terminate the protocol
2395 always with timeout.
2397 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * The client's Client ID was created initally from the wrong
2400 nickname (it could have been in format nick@host) in the
2401 silc_server_new_client. Affected file silcd/packet_receive.c
2403 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Added some SILC_LOG_ERROR's to various error conditions
2406 if client could not be added to ID cache. Affected files
2407 silcd/packet_receive.c and silcd/server.c.
2409 * When client's sock->user_data is freed, NULL also the
2410 client->router and client->connection pointers. Added check
2411 for these pointers being NULL to various places around the
2412 code. Affected file silcd/server.c.
2414 * Added client->data.registered == TRUE checks to various
2415 places around the code to assure that unregistered client's
2416 are not handled when it is not allowed. Affected file
2419 * Added `bool registered' fields to all
2420 silc_idlist_[server|client]_get_* routines to indicate whether
2421 the fetched client needs to be registered or not. Affected
2422 file silcd/idlist.[ch].
2424 * Add your own entry as registered to the ID cache in the
2425 server. Affected file server.c.
2427 * Fixed a bug in silc_server_new_server. The SilcServer was
2428 set as the new server's context instead of SilcServerEntry.
2429 This naturally caused some weird bugs.
2431 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Do not delete the channel rekey task when adding it
2434 for in silc_server_create_channel_key.
2436 * Changed the silc_server_create_channel_key to return
2437 TRUE or FALSE to indicate the success of the channel key
2440 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Fixed MSVC++ project files and added missing files to
2443 Makefiles under win32/.
2445 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * Do not add TCP_NODELAY flag if the operating system
2448 does not have it defined. Affected files are
2449 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2451 * Fixed buffer overflow from Irssi SILC Client. Affected
2452 file irssi/src/fe-common/core/themes.c.
2454 * Fixed double free in client library in the file
2455 lib/silcclient/client.c when disconnecting from server.
2457 * Applied double free patch from cras to Irssi SILC client.
2458 Affected files irssi/src/core/[modules/expandos].c
2460 * Fixed the disconnection handling to Irssi SILC Client.
2461 The application must call silc_client_close_connection
2462 in ops->connect client operation in case of failure of
2463 the connection. Affected file is
2464 irssi/src/silc/core/client_ops.c.
2466 * Do not set sock->protocol to NULL in the function
2467 silc_client_close_connection after executing the protocol's
2468 final callback since the sock might not be valid anymore.
2469 Affected file lib/silcclient/client.c.
2471 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Do not enable SILC_THREADS if the linking with libpthread
2474 did not happen. Affected file configure.in.pre.
2476 * Added notion to protocol specification that server must
2477 verify the sent authentication payload with CMODE when
2478 setting the channel founder key. Implemented it to the
2479 server. Affected file silcd/command.c.
2481 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Added _EXTRA_DIST SILC distribution variable to the
2484 distributions file. It is used to conditionally add extra
2485 files or directories to the specific distribution. Affected
2486 files ./prepare, Makefile.am.pre and distributions.
2488 Removed the `_' from the start of the distribution names.
2491 * Added README.WIN32 for instructions to compile the Toolkit
2494 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Fixed a double free in disconnection in the server. Affected
2497 file is silcd/server.c.
2499 * Fixed the lib/silcske/groups.c to work now also with GMP
2500 MP library. The string conversion did not work when using
2501 specific base and the base is indicated in the string as well.
2503 * Created win32/ directory which now includes MSVC++ specific
2504 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2505 It will appear only in the toolkit distribution
2507 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Changed the key material distribution function in case when
2510 the hash output is too short. The data is now concatenated
2511 a bit differently than it used to. Made the change to the
2512 SKE protocol specification.
2514 * Added better GMP detection to configure.in.pre. A patch
2517 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Fixed a minor bug in SKE that might cause some problem on
2520 some platforms. Affected file lib/silcske/silcske.c.
2522 * Added the cookie checking for initiator in the SKE. It checks
2523 that the responder returns the sent cookie unmodified. The
2524 affected file is lib/silcske/silcske.c. Added new SKE
2525 error type INVALID_COOKIE that can be sent during the
2526 negotiation. Fixed some memory leaks as well.
2528 * Added the "invalid cookie" error message to Irssi SILC client's
2531 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Added `task_max' field to the SilcClientParams to indicate
2534 the maximum tasks the scheduler can handle. If set to zero,
2535 default values are used. Affected file lib/silcclient/silcapi.h.
2537 * Fixed memory leaks in silc_client_close_connection. Affected
2538 file lib/silcclient/client.c.
2540 * Added silc_client_del_client_entry to client library to free
2541 all memory of given client entry. Affected file is
2542 lib/silcclient/idlist.[ch].
2544 * Added new functions silc_client_del_channel and
2545 silc_client_del_server to delete channel and server entries.
2546 Affected file lib/silcclient/[silcapi.h/idlist.c].
2548 * Removed silc_client_del_client_by_id from silcapi.h.
2550 * Fixed the INFO command to return the server's own info
2551 correctly when querying by Server ID. Affected file is
2554 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Removed the non-blocking settings in WIN32 code in the
2557 silc_sock_[read/write] and added SleepEx instead. Affected
2558 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2559 of input data is now checked with FIONREAD and ioctlsocket.
2561 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Call silc_schedule_task_del_by_context in the
2564 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2565 Affected file lib/silccore/silcprotocol.c.
2567 * Call silc_protocol_cancel for active protocols in the
2568 silc_server_close_connection if the funtion
2569 silc_server_free_sock_user_data has not been called.
2570 Affected file silcd/server.c.
2572 * Generic tasks cannot be deleted using the del_by_fd
2573 task deleting function since generic tasks does not match
2574 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2576 * Added a notion to SILCOPER help file that the SILCOPER works
2577 only on router server, not on normal server.
2579 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Added for WIN32 support for the new scheduler as well.
2582 Affected file lib/silcutil/win32/silcwin32schedule.c.
2584 * Fixed the SHA1 implementation to work on various platforms.
2586 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2589 API. It is part of the scheduler now. Everything else is
2590 as previously but some functions has changed their names.
2591 Checkout the lib/silcutil/silcschedule.h for the interface.
2592 Updated all applications to use the new interface. Affected
2593 files are lib/silcutil/silcschedule.[ch].
2595 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Found a bug in the SKE implementation. The HASH value,
2598 specified by the protocol, was not computed correctly. The
2599 public key of the responder was not added to the computation
2600 even though it is mandatory. Affected file lib/silcske/silcske.c.
2601 This unfortunately causes incompatibilities with older
2602 clients and servers.
2604 * Added WIN32 specific network init and uninit functions:
2605 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2606 the Winsock2. Affected file lib/silcutil/silcnet.h and
2607 lib/silcutil/win32/silcwin32net.c.
2609 * Set the socket always to nonblocking mode on WIN32 after
2610 reading data or writing data. Affected file is
2611 lib/silcutil/win32/silcwin32sockconn.c.
2613 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Fixed various compilation problems under WIN32. Affected
2616 files lib/silcutil/win32/silcwin32thread.c and
2617 lib/silcutil/win32/silcwin32schedule.c.
2619 * Removed all _internal.h #includes from public header
2620 files. Internal headers must never be included from
2623 Removed also the lib/silcske/payload_internal.h file.
2625 * All include files that may be needed (public and some others
2626 included by the public headers) by application developers are
2627 now copied to the ./includes directory. It does not copy any
2628 internal headers. Affected file Makefile.defines.pre and all
2629 Makefile.am's under lib/ and subdirs.
2631 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Do not change the ~/.silc directory's permissions automatically.
2634 Affected file irssi/src/silc/core/clientutil.c.
2636 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2638 * Do not cancel the protocol in silc_server_close_connection
2639 it might cause recursion. Now cancelled in the function
2640 silc_server_free_sock_user_data. Affected file silcd/server.c.
2642 * Fixed the silc_server_remove_clients_by_server to regenerate
2643 the channel keys correctly finally. Added also new function
2644 silc_server_remove_clients_channels to actually do it.
2645 Affected file silcd/server.c.
2647 * Fixed the silc_server_new_channel to not crash by giving
2648 wrong router to the new channel. Affected file is
2649 silcd/packet_receive.c.
2651 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2654 which is given as argument to the silc_client_alloc now.
2655 It can be used to configure the client and set various parameters
2656 that affect the function of the client.
2658 * The USERS command in server did not check whether the channel
2659 is private or secret. Affected file silcd/command.c.
2661 * Added new argument to the USERS command in protocol specification.
2662 The USERS command now can take the channel name as argument
2663 as well. Added support for this in client and server and
2664 updated the protocol specs.
2666 * Completed the GETKEY command in client. It can be now used
2667 to fetch also servers public key not only some clients.
2668 Affected files lib/silcclient/command[_reply].c.
2670 * Added silc_client_get_server to return server entry by the
2671 server name. Affected files lib/silcclient/silcapi.h and
2674 * Redefined the IDENTIFY command in protocol specification to be
2675 more generic. It now can be used to query information about
2676 any entity in the SILC Network, including clients, servers and
2677 channels. The query may be based either the entity's name
2678 or the ID. Added support for this in both client and server.
2680 Affected files silcd/command.c and lib/silcclient/command.c
2681 and command_reply.c.
2683 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2684 the _from_client and _from_server functions. Affected file
2687 * Added silc_client_get_channel_by_id_resolve to the file
2688 lib/silcclient/silcapi.h to resolve channel information by
2689 its ID. Added also silc_client_get_channel_by_id that
2690 does not resolve it from the server.
2692 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * Added SilcServerEntry context into the client library
2695 to represent one server. The INFO command now allocates
2696 these to save the resolved server info. For now on the
2697 client library will also keep information about servers,
2698 connected and resolved with INFO.
2700 The INFO command now allocates the SilcServerEntry context
2701 and saves the server info there. The COMMAND_REPLY in
2702 the INFO now returns the parameters to application in
2703 same order as defined in the protocol specification.
2705 The entries are cached in the client->server_cache.
2707 * The INFO command is now issued after received the Client ID
2708 from the server. Affected file lib/silcclient/client.c.
2710 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2711 to the application as the mode changer might be server.
2712 It is guaranteed that NULL is not returned anymore to the
2713 application. Affected file lib/silcclient/client_notify.c.
2715 The ID Type is now also passed to the application so that
2716 it can check whether the returned entry is SilcClientEntry
2719 Added new function silc_client_get_server_by_id to return
2720 the server entry by ID. Affected files are the
2721 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2723 * Do not create the channel in the Irssi SILC Client when issuing
2724 the JOIN command but when received the sucessful JOIN command
2725 reply. Otherwise the channel might get created even though we
2726 could not join it. The Affected file is
2727 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2729 * Fixed a channel joining bug in router. The router must also
2730 check the channel modes, invite and ban lists etc. when serving
2731 the JOIN command sent by normal server. Affected file is
2732 silcd/command.c. The router now resolves the client's
2733 information from the server who sent the JOIN command if it
2734 does not know it, and processes the JOIN command only after
2737 * Changed the SilcCommandCb to take new argument; void *context2.
2738 Affected file lib/silccore/silccommand.h
2740 The second argument in the command callbacks in the server now
2741 includes the SilcServerCommandReplyContext if the command was
2742 called as pending command callback from the command reply.
2743 Otherwise it is NULL. When called as pending the status of the
2744 command reply will be checked and if it was erronous the
2745 error will be sent to the original sender of the command.
2746 This way the client always receives the error messages even
2747 though the server was actually the one who received the error
2748 when it resent the command to router, for example. Affected
2749 files silcd/command[_reply].[ch].
2751 * Fixed sending WHOWAS command's error message to client if
2752 the requested client could not be found. It was missing.
2755 * Changed the CMODE and CUMODE commands reply arguments in the
2756 protocol specification. The Channel ID is now sent in both
2757 of the commands to identify the channel. Implemented this
2758 new feature to the client and server. Affected files
2759 lib/silcclient/command_reply.c and silcd/command.c.
2761 * Made better checks for invite and ban lists in the JOIN
2762 command in server. Affected file silcd/command.c.
2764 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * The server now performs the incoming host IP/DNS lookup
2767 using the silc_socket_host_lookup and thus does not block
2768 the server anymore. Affected file silcd/server.c.
2770 * Completed the multi-thread support for SILC Scheduler in
2771 the lib/silcutil/silcschedule.c.
2773 * Fixed the configure.in.pre to detect the pthread correctly
2776 * Fixed a deadlock in silc_task_queue_wakeup in the file
2777 lib/silcutil/silctask.c.
2779 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Added new function silc_schedule_wakeup that is used in
2782 multi-threaded environment to wakeup the main thread's
2783 schduler. It needs to be used when a thread adds a new task
2784 or removes a task from task queues. After waking up, the
2785 scheduler will detect the task queue changes. If threads
2786 support is not compiled in this function has no effect.
2787 Implemented the wakeup mechanism to both Unix and WIN32
2788 systems. Affected files are lib/silcutil/silcschedule.[ch],
2789 lib/silcutil/unix/silcunixschedule.c and the
2790 lib/silcutil/win32/silcwin32schedule.c.
2792 * Added new function silc_task_queue_wakeup to wakeup the
2793 scheduler by the specified task queue. Affected file
2794 lib/silcutil/silctask.[ch].
2796 * The silc_socket_host_lookup_start now wakes up the scheduler
2797 after adding the timeout task. Affected file is
2798 lib/silcutil/silcsockconn.c.
2800 * The silc_socket_host_lookup is synchronous now if the threads
2801 support is not compiled in. However, the callback is still
2802 called asyncronously through the scheduler, anyway. Affected
2803 file lib/silcutil/silcsockconn.c.
2805 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Added new function silc_socket_host_lookup to perform
2808 asynchronous IP and FQDN lookups for the socket connection.
2809 Affected files lib/silcutil/silcsockconn.[ch].
2811 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2813 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2814 that may or may not compile the mutex support in.
2816 Changed the silc_mutex_alloc interface. It allocates the
2817 mutex now to the sent pointer and returns TRUE or FALSE.
2819 Affected file lib/silcutil/silcmutex.h.
2821 * Wrote the SILC Task Queue interface to support multi-threads.
2822 Affected file lib/silcutil/silctask.[ch].
2824 * Wrote the SILC Scheduler to support multi-threads. Affected
2825 file lib/silcutil/silcschedule.c.
2827 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2830 in lib/silcutil/win32/.
2832 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Defined SILC Mutex API and SILC Thread API and implemented
2835 them for Unix. Affected files are
2836 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2837 lib/silcutil/unix/silcunixmutex.c and
2838 lib/silcutil/unix/silcunixthread.c.
2840 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Fixed the silc_server_remove_clients_by_server's channel
2843 key re-generation. The hash table handling was incorrect
2844 and would not work with many channels. Affected file is
2847 * Fixed some memory leaks around the server code.
2849 * Rewrote the silc_server_get_users_on_channel to support IPv6
2850 based Client ID's. Affected file silcd/server.c.
2852 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2853 specification. However, a separate document must be written
2854 to define the detailed signing procedure and the payload
2855 associated with the flag. Defined the flag to the
2856 lib/silccore/silcchannel.h as well.
2858 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Changed the dynamic tables to static size tables in the
2861 lib/silccrypt/silchmac.c.
2863 * Removed GCC dependencies from the code. A patch by cras.
2865 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Do not show the error "Error receiving packet bla bla"
2868 in server if it really was not an error (-2 means that reading
2869 is pending). Affected file silcd/server.c.
2871 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Fixed a possible crash in silc_server_remove_clients_by_server
2874 in silcd/server.c. Fixed there also some memory leaks.
2876 * Fixed the silc_idlist_replace_client_id. It could replace
2877 wrong key in the hash table. Affected file silcd/idlist.c.
2879 * Do not check whether there are global users on the channel
2880 if the channel->global_users is FALSE. Affected functions
2881 silc_server_remove_from_one_channel and
2882 silc_server_remove_from_channels in silcd/server.c. Also,
2883 do not check if the removed client is local as we can be
2884 sure that global client was not removed from the channel
2885 and checking for global users is not needed.
2887 * The silc_server_remove_clients_by_server now re-generates
2888 the channel keys correctly for those channels that had
2889 clients removed from them. Affected file silcd/server.c.
2891 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Found the reason of random crashes in the server. We weren't
2894 ignoring the SIGPIPE signal (which can be sent in write())
2895 and it crashed the server. Affected file silcd/silcd.c.
2897 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Assure that sock->user_data is not NULL in the function
2900 silc_server_packet_send in silcd/packet_send.c.
2902 * Disconnect the remote connection if it could not be added
2903 to any ID lists in the server. The affected file is
2906 * Check in silc_server_packet_send[_real/dest] that the
2907 socket is not disconnecting and ignore the data if it is.
2908 Affected file silcd/packet_send.c.
2910 * Define inline to __inline on native WIN32 compilation.
2911 Affected file includes/silcwin32.h.
2913 * Added some explicit type casts for inline code since MSVC
2914 require them. Affected files lib/silcutil/silcbuffer.h,
2915 lib/trq/silcdlist.h and lib/trq/silclist.h.
2917 * Print warning in log files from now on if the packet
2918 decryption fails. Affected file silcd/server.c.
2920 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Changed the `say' client operation's interface to accept
2923 new `type' argument to indicate the type of the message sent
2924 by the library. The application may filter the library's
2925 messages according the type. The affected file is the
2926 lib/silcclient/silcapi.h.
2928 * Added two new functions to lib/silcclient/silcapi.h:
2929 silc_client_del_client and silc_client_del_client_by_id.
2930 Affected file lib/silcclient/idlist.c.
2932 * Moved the clientincludes.h from includes/ to silc/ and
2933 serverincludes.h from includes/ to silcd/.
2935 * The modes for the CMODE and CUMODE are now passed as
2936 uint32 for application with COMMAND_REPLY. The affected
2937 file is lib/silcclient/command_reply.c.
2939 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * /WHOIS without arguments shows client's own information.
2942 Affected file lib/silcclient/command.c.
2944 * Changed PING to not accept any arguments. The specs
2945 says that client can ping only the connected server so
2946 requiring an argument is not needed. Affected file is
2947 lib/silcclient/command.c.
2949 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Fixed a fatal bug in private message sending and reception
2952 encryption and decryption when using private message keys.
2953 The implementation was incorrect and did not follow the
2954 specification. It causd that some of the message were
2955 lost since it did not use the sending and receiving keys
2956 as the protocol suggests. This has been fixed and will cause
2957 incompatibilities with older clients when sending private
2958 message encrypted with private message keys. Affected files
2959 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2960 and various other in Irssi SILC Client.
2962 Added `responder' boolean argument to the functions
2963 silc_client_add_private_message_key[_ske] to indicate when
2964 the key is added as responder or initiator of the key
2967 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Removed the silc_ske_check_version function and created
2970 a SilcSKECheckVersion callback. Added also a function
2971 silc_ske_set_callbacks that is now used to set all SKE
2972 callbacks. The callback functions are not given to
2973 the SKE functions anymore, but this function is used to
2976 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2978 * Added `silc_version' argument to the silc_client_alloc
2979 to define the version of the application for the library.
2980 The library will use the version string to compare it
2981 against the remote host's (usually a server) version
2982 string. Affected file lib/silcclient/silcapi.h
2984 * Added the KE protocol context to Key Agreement context
2985 in client library so that we can abort the SKE if it
2986 is in process when we get timeout. Affected file is
2987 lib/silcclient/client_keyagr.c.
2989 * Do not resolve the client ID forever if it returns in the
2990 first time that such client does not exist. This was done
2991 for example with private message. Affected file is
2992 lib/silcclient/client_prvmsg.c.
2994 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2996 * Do not add regex.h for WIN32. The affected file
2997 includes/silcincludes.h.
2999 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3000 not work yet 100%. It generates the DLL's automatically
3001 when compiling with --with-win32 under cygwin.
3003 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * lib/contrib/regex.c is not compiled on WIN32.
3007 * Added silc_net_get_socket_opt function to the
3008 lib/silcutil/silcnet.h.
3010 * Added includes/silcwin32.h for WIN32 specific includes
3013 * Do not use ptime structure or any of the posix process
3014 functions on WIN32 in lib/silccrypt/silrng.c.
3016 * Added silc_gettimeofday to provide generic function
3017 for struct timeval on all platforms. Added the function
3018 to lib/silcutil/silcutil.h.
3020 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3023 library as they clearly belong there. As a plus side we
3024 can make the actual socket connection routines platform
3027 Added also new generic function silc_socket_read and
3028 silc_socket_write (that used to be silc_packet_[read/write].
3029 The implementation of these are platform specific.
3031 * Added WIN32 specific routines of silc_socket_[read/write]
3032 to lib/silcutil/win32/silcwin32sockconn.c.
3034 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Added preliminary support for native WIN32 compilation under
3037 cygwin (using the -mno-cygwin option for GCC) to the
3038 ./configure.in.pre. The --with-win32 now prepares the
3039 compilation for native WIN32.
3041 * Rewrote the SILC Scheduler interface in the file
3042 lib/silcutil/silcschedule.h. The scheduler is now context
3043 based and does not have anymore any global static scheduler.
3044 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3045 and created lib/silcutil/win32 directory for WIN32 based
3048 * Added Unix specific network routines to the
3049 lib/silcutil/unix/silcunixnet.c and the old
3050 lib/silcutil/silcnet.c includes now only generic routines.
3052 Added WIN32 specific network routines to the
3053 lib/silcutil/win32/silcwin32net.c.
3055 * Added Unix specific utility functions from the
3056 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3058 * Added WIN32 SILC Scheduler to the file
3059 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3062 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3064 * Do not handle JOIN notify in the server if the target client
3065 is not registered (idata->registered == FALSE). The affected
3066 file is silcd/packet_receive.c.
3068 * Update the nickrec->founder in event_cumode in the Irssi SILC
3069 client. Affected file irssi/src/silc/core/silc-channels.c.
3071 * Fixed the CUMODE_CHANGE notify handling in the server when
3072 server and router are announcing their clients on channels.
3073 Now the mode changes are saved and notified correctly. The
3074 affected file is /silcd/packet_receive.c.
3076 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3077 They really did not replace the cache entry in the ID Cache.
3078 Now they do that. Affected file silcd/idlist.c.
3080 * Fixed the KICK notify handling in the Irssi SILC client to
3081 update the channel records so that the kicked client does not
3082 appear to be on the channel. The affected file is
3083 irssi/src/silc/core/silc-channels.c.
3085 * Always update the conn->current_channel when executing command
3086 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3088 * Fixed the KILL notify handling in Irssi SILC client to remove
3089 the killed client on all channels.
3091 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Fixed the silc_parse_command_line to remove extra spaces
3094 from the start and end of the arguments. Affected file is
3095 lib/silcutil/silcutil.c.
3097 * Cancel and free any active protocol in the function
3098 silc_server_close_connection. Affected file silcd/server.c.
3100 * Cancel and free any active protocol in the function
3101 silc_client_close_connction. Affected file is
3102 lib/silcclient/client.c.
3104 * Do not execute the KILL command for clients that are in
3105 history (ie. they are not in the network). Affected file is
3108 * Fixed KILL notify handling, client does not crash anymore.
3109 Affected file irssi/src/silc/core/silc-channels.c.
3111 * Reduced the default packet buffer size from 2048 to 1024 in
3112 lib/silccore/silcpacket.c.
3114 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3115 counter to the SKE context that is incresed when the SKE library
3116 performs async operation outside the library. If the outside
3117 process frees the SKE context and FREED status will be set
3118 and the library will detect after the sync operation that the
3119 libary is freed. The affected files are
3120 lib/silcske/silcske[_status].[ch].
3122 * Resolve the client entry information in the function
3123 silc_client_channel_message to assure that NULL pointer is not
3124 passed as client entry to the application. */
3126 * Fixed the task timeout calculation to assure that there is
3127 never negative timeouts. The affected file is
3128 lib/silcutil/silcschedule.c.
3130 * Fixed the channel user mode notification sending in server.
3131 It was sent point-to-point to the router (or to server by router)
3132 but it needs to be destined to a channel. The routines now
3133 supports sending the channel user mode notifys to the channels
3134 when announcing clients and channels. Affected files are
3135 silcd/server.c and silcd/packet_receive.c.
3137 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3138 It did not actually replace the old channel entry in the cache.
3139 Affected file lib/silcclient/client_notify.c.
3141 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Fixed a possible crash in silc_packet_send_prepare. It now
3144 assures always that there is enough space in the buffer and
3145 at the tail area of the buffer (for MAC).
3147 Fixed the inbound buffer reallocation in silc_packet_read.
3148 It was old code and did not handle the reallocation correctly.
3151 The affected file is lib/silccore/silcpacket.c.
3153 * Fixed buffer overflow in silc_parse_nickname in the file
3154 lib/silcutil/silcutil.c.
3156 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * make install generates new server keys only if there is not
3161 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3164 Added check that if the NOREPLY is set then we will not send
3165 the away message. This avoids infinite loop of away messages
3166 if both clients are away. The affected file is
3167 lib/silcclient/client_prvmsg.c.
3169 * Fixed client crash if /NICK was given without arguments.
3170 Affected file lib/silcclient/command.c.
3172 * Server does not send the invite list in INVITE command back
3173 to the client if the list was not altered. Added this notion
3174 to the protocol spec as well. Affected file silcd/command.c.
3176 Fixed possible crash in INVITE command by checking the
3177 value of silc_server_get_client_route command.
3179 * Fixed the INVITE notify type handling. The arguments are now
3180 taken in correct order and client does not crash. The affected
3181 file is irssi/src/silc/core/silc-channels.c.
3183 Removed the "Inviting xxx to channel" message from the
3184 client library away and let the application handle it.
3185 Affected file lib/silcclient/command.c. Added that message
3186 to Irssi SILC client's message formats.
3188 * Fixed CMODE command crash in client. It now checks the
3189 amount of arguments correctly and does not crash. The affected
3190 file is lib/silcclient/command.c.
3192 * Do not create new channel automatically in silc_channels_join
3193 but check whether the channel by that name already exists.
3194 Affected file irssi/silc/core/silc-channels.c.
3196 * Do not send the SERVER_SIGNOFF to router if the disconnected
3197 entity was the router. Affected file silcd/server.c.
3199 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3200 SILC client as it was missing from there.
3202 Added the handling of the KICK notify to the Irssi SILC client
3203 as it was missing. Added "you have been kicked" message to
3204 Irssi SILC client's message modules formats.
3206 Added the handing of the KILL notify to the Irssi SILC client
3207 as it was missing. Added the kill message module formats
3210 The affected file is irssi/src/silc/core/silc-channels.c.
3212 * The router did not save the channel mode the server announced.
3213 Affected file silcd/packet_receive.c.
3215 * Fixed a possible crash in INFO command in server. If the
3216 server did not provide the server info it crashed. Affected
3217 file silcd/command.c.
3219 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Fixed the GETKEY command in the server to check also the
3222 global list. Otherwise the GETKEY would not work correctly
3223 in normal SILC server. Affected file silcd/command.c.
3225 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Fixed GETKEY crash, it crashed if the command did not succseed.
3229 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3232 is now real and not just an macro interface to GMP.
3234 Removed the entire GMP from the source tree and imported new
3235 NSS MPI library instead. Reason for removing GMP is that it is
3236 extremely large and compiles extremely slow. The NSS MPI
3237 is only a few files and compiles in less than 10 seconds.
3238 The speed is also about the same as GMP. The MPI is imported
3239 to lib/silcmath/mpi.
3241 If the system has GMP installed we will still use the GMP.
3242 If it is not then the NSS MPI will be compiled.
3244 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Merged a long nickname (127 characters long) crash bugfix from
3247 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3249 * Merged a freed memory reference bugfix from Irssi CVS tree.
3250 Affected file irssi/src/core/commands.c.
3252 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Added the server's public key sving and verification to the
3255 server when performing the SKE. This was missing and the
3256 remote server's (or router's) public key was accepted without
3257 checking whether we have it previously or trust it at all.
3258 Affected file silcd/protocol.c.
3260 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Check in the silc_server_timeout_remote if protocol is active
3263 and make sure that the protocol's final callback is called so
3264 that all memory if freed. Affected file silcd/server.c.
3266 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * silc_server_whois_send_reply crashed the server if the nickname
3269 was 127 characters long. Affected file silcd/command.c.
3271 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Added sanity check to the silc_server_new_client. If the hostname
3274 is provided inside username then check that the provided hostname
3275 really is the same as the resolved one. If the hostname was not
3276 resolved then check it from the public key. Affected file is
3277 silcd/packet_receive.c.
3279 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3280 if the server disconnected us and the connection is not valid
3281 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3283 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3284 the library to the lib/silcutil/silcutil.[ch].
3286 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Close log file after open. Affected file
3289 lib/silcutil/silclog.c.
3291 * Check whether sock == NULL in silc_client_send_packet and return
3292 if it is. Affected file lib/silcclient/silcclient.c.
3294 * Check rec->entry == NULL in the Irssi SILC Client before
3295 sending the channel message. Affecte file is
3296 irssi/src/silc/core/silc-servers.c.
3298 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Merged a splitted window bugfix from Irssi CVS tree. The
3301 affected file is irssi/src/fe-text/textbuffer-view.c.
3303 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3304 It did not print nickname.
3306 * Improved the distributions system a bit.
3308 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3311 irssi/src/fe-text/gui-window.c.
3313 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3314 to in-active server. The affected file is
3315 irssi/src/silc/core/client_ops.c.
3317 * Resolve the client in USERS command reply if the entry does
3318 not have username resolved. The affected file is
3319 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3320 command to WHOIS command to really resolve stuff. The USERS
3321 is not used any more in any critical section so WHOIS can
3322 be used even though it might be slower than IDENTIFY.
3324 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3327 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Changed the protocol API a bit more consistent in the
3330 lib/silccore/silcprotocol.[ch].
3332 * Changed the following headers to ROBODoc format:
3334 lib/silccore/silcpayload.h
3335 lib/silccore/silcprotocol.h
3336 lib/silccore/silcsockconn.h
3338 All core library headers are now formatted.
3340 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Fixed a bug in Irssi SILC client; do not show that you are
3343 server/router operator if you really are not. Affected file is
3344 irssi/src/silc/core/client_ops.c.
3346 * Renamed silc_command_free_payload to silc_command_payload_free.
3347 Affected file lib/silccore/silccommand.h
3349 * Added silcmath.h to include the prototoypes of various routines
3350 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3353 * Changed the following headers to ROBODoc format:
3355 lib/silccore/silcchannel.h
3356 lib/silccore/silccommand.h
3357 lib/silccore/silcid.h
3358 lib/silccore/silcidcache.h
3359 lib/silccore/silcmode.h
3360 lib/silccore/silcnotify.h
3361 lib/silccore/silcpacket.h
3362 lib/silcmath/silcmath.h
3364 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3366 * Added checking to the server code not to start the server if
3367 ciphers and stuff are not configured properly. Affected files
3368 silcd/serverconfig.[h] and silcd/server.c.
3370 * Changed the layout of the header files of the public interfaces
3371 in the SILC libraries. The new layout supports ROBODoc
3372 documentation tool (and some others) so that it is easy to create
3373 a library reference manual. All the other headers and source
3374 code must still follow the CodingStyle document. Also source
3375 code must not include these ROBODoc stuffs, only the headers.
3376 Furthermore, all public interface headers must now be named
3377 by using `silc' prefix, example: silcapi.h, silccipher.h.
3378 Some files were renamed due to this. All the other headers
3379 must not be used as public interfaces. I will update the
3380 CodingStyle document later. Changed following headers, so far:
3382 lib/silcclient/silcapi.h
3383 lib/silccore/silcauth.h
3384 lib/silccore/silcprivate.h
3385 lib/silccrypt/silcdh.h
3387 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Removed silc_client_packet_send_flush from the client library
3392 as it is not needed. Affected file lib/silcclient/client.[ch].
3394 * Added printing of message of unresolved authentication method
3395 to the Irssi SILC client. Added it to the module formats.
3396 Removed the same message from the client library.
3398 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Added new distribution feature, DISTLABEL. Every distribution
3401 can define own preprocessor label that can be used in the
3402 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3403 file distributions, acconfig.h.pre and prepare.
3405 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Added Makefile.defines_int to include the actual definitions
3408 for Makefile.defines.in. Tested the new distribution system,
3409 created distributions and tested installation.
3411 * Added AWAY message printing to the Irssi SILC client. Added
3412 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3414 * Added SCONNECT command to call the SILC's CONNECT command.
3415 Cannot use CONNECT directly since Irssi uses that internally.
3416 Affected file irssi/src/silc/core/silc-servers.c.
3418 Added ACTION local command. It is same as ME command but takes
3419 the channel as mandatory argument.
3421 Rewrote some of the Irssi's help files to suite for SILC
3424 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Added Makefile.defines[.in] that should for now on be included
3427 in all Makefile.am file in the source tree. That file includes
3428 all common compilation definitions for SILC source tree.
3430 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Minor changes to the ./prepare script to change the package
3433 name according the distribution name to the configure.in.
3435 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Created new distribution system. Added file `distributions'
3438 that defines all the distributions that can be created out of
3439 the SILC source tree. The ./prepare script now reads that
3440 file to determine how to prepare the distributions. The
3441 first argument to the ./prepare is the name of the distribution
3442 and second is the version of the distribution. If given
3443 without arguments it creates the default (toolkit) distribution
3444 with the default version (defined in ./prepare).
3446 All Makefile.am files that are subject to the distributions
3447 are now named as Makefile.am.pre. These are ./Makefile.am
3448 and lib/Makefile.am. Others may be changed later.
3450 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Added invite list, ban list, some key management and connection
3453 error message printing to module formats in the Irssi SILC client.
3455 * Added new silc_client_set_away_message to set the away message
3456 that is back to the person who sent private message. The
3457 affected file lib/silcclient/silcapi.h and the
3458 lib/silcclient/client_prvmsg.c.
3460 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3462 * Fixed the private message sending in the Irssi SILC client,
3463 added local command KEY to the Irssi SILC client.
3465 Added key management and key agreement message formats to the
3466 irssi/src/fe-common/silc/module-formats.[ch].
3468 Added USERS (alias WHO) printing, server/router operator
3469 indication and LIST command printing to the module formats.
3471 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Fixed channel joining notify handling, cumode notify handling
3474 from Irssi SILC client.
3476 * Added SILC specific module-formats to the Irssi SILC client so
3477 that SILC specific message hilighting, colors etc is possible.
3478 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3480 Added channel mode, channel user mode, actions, notices,
3481 whois and whowas printing to the the module-formats.c.
3483 * Fixed a bug in channel deletion in the server. The channel
3484 is not left to the cache even if the channel founder auth mode
3485 is set when there are no users anymore on the channel. Affected
3486 file silcd/server.c.
3488 * The silc_net_localhost now resolves the entire hostname including
3489 the domain name. Affected file lib/silcutil/silcnet.c.
3491 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Changed the ask_passphrase client operation to be ascynchronous.
3494 It has now a completion callback and a context that the
3495 application must call after it has got the passphrase from
3496 the user. Affected files lib/silcclient/silcapi.h,
3497 lib/silcclient/protocol.c, lib/silcclient/command.c and
3500 Added SilcAskPassphrase callback that the application calls
3501 to deliver the passphrase to the library.
3503 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3504 The public key verification and especially a certificate
3505 verification is asynchronous procedure.
3507 Added new SILC_SKE_STATUS_PENDING status to indicate the
3508 request is pending and a callback will be called to finalize
3511 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3512 indicate that remote end did not send its public key (or
3513 certificate), even though we require it. Added check for this
3514 condition in the SKE. This was a security bug, now fixed.
3516 Defined new SilcSKEVerifyCbCompletion callback that is called
3517 when the verification process is completed.
3519 The affected files lib/silcske/silcske_status.h and
3520 lib/silcske/silcske.[ch].
3522 * Changed the verify_public_key client operation to be async
3523 as well. Defined SilcVerifyPublicKey callback that is used to
3524 indicate the success of the public key verification process.
3526 Changed the server and client to use the new async client
3529 * Changed the Irssi SILC client's internal scheduler to be called
3530 twice as many times as it used to be. As a result the client
3531 should be a bit faster now. Affected file is
3532 irssi/src/silc/core/silc-core.c.
3534 * Added support to Irssi SILC client of asynchronous public key
3535 verification and passphrase inquiry. Affected file is
3536 irssi/src/silc/core/silc-core.c.
3538 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Do not say "You have left channel %s" in client library.
3541 Moved it to the application. Affected files are
3542 lib/silcclient/command.c and silc/client_ops.c.
3544 * Fixed silc_client_get_clients. Command context was not
3545 duplicated and was freed memory in the callback. Affected
3546 file lib/silcclient/idlist.c.
3548 * Do not say "you are now talking..." on JOIN command in the
3549 client library. The appliation must handle it.
3551 * Do not say ".. changed topic to" in command reply in the
3552 client libary. The application must handle it.
3554 * Fixed TOPIC command sending in the client library.
3556 * Fixed a memory leak in silc_client_command_free in the file
3557 lib/silcclient/command.c.
3559 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Imported a modified version of Irssi client to the source tree.
3562 The Irssi will be used to create a new client called
3563 Irssi SILC. Imported to irssi/.
3565 Added silc_core_init_finish function to the Irssi. Affected
3566 file irssi/configure.in.
3568 A lot changes in the Makefile.ams around the irssi tree.
3570 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Do not rehash if the new size is same as the old size of the
3573 hash table, in the silc_hash_table_rehash*. The affected file
3574 lib/silcutil/silchashtable.c.
3576 * Replaced hash_table_del_by_context calls from the server
3577 (when channel->user_list and client->channels) to the
3578 hash_table_del as it is sufficient and faster.
3580 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Added silc_hash_table_list, silc_hash_table_get and the
3583 SilcHashTableList structure to provide an alternative way to
3584 traverse the hash table. The affected files are
3585 lib/silcutil/silchashtable.[ch].
3587 * Changed the server's idlist routines to use the hash table
3588 routines to optimize the code.
3590 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Replaced the client entry's `channel' list and channel entry's
3593 `user_list' list to hash tables for optimized lookup. Changed
3594 the code to use the hash table interface around the code.
3595 Affected file lib/silcd/idlist.[ch].
3597 * Added `auto_rehash' boolean argument to the function
3598 silc_hash_table_alloc to indicate whether the hash table should
3599 auto-rehash when it thinks is appropriate time. It will
3600 increase the hash table size if the there is twice as much
3601 entries in the table than the size of the table, and will
3602 decrease the size if there are twice as less entries than
3603 the size of the table.
3605 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3609 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * silc_idcache_purge_by_context deletes the entry now by context
3612 as it is supposed to do. Affected file lib/silccore/idcache.c.
3614 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3615 client is not anymore valid (WHOWAS givens the info) and not
3616 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3618 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Removed the `data' and `data_len' arguments from the ID Cache
3621 interfaces and added `name' argument. ID Cache does not handle
3622 anymore the binary data only a names associated with given ID.
3624 * When hashing a Client ID with silc_hash_id the entire ID is
3625 not hashed anymore, instead only the hash of the Client ID is
3626 hashed. This way we can access the Client ID from the cache
3627 with Client ID but with the hash of the ID (which is a hash of
3628 the nickname) as well without any difference in performance.
3630 Added also silc_idcache_find_by_id_one_ext to do one on one
3631 searching when we have the actual ID. Added also function
3632 silc_hash_client_id_compare. The affected files are
3633 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3635 * When hashing the name associated with a ID it is always done
3636 in lowercase. This way we can access the cache without worrying
3637 about case-sensitivity, even though, for example nicknames are
3640 * Fixed a bug in server with channel message sending. It put
3641 wrong ID type as destination ID. The affected file
3642 silcd/packet_send.c.
3644 * silc_idcache_del_by_context now deletes from all hash tables
3645 by context. Affected file lib/silccore/idcache.c.
3647 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Changed the client library to use the new ID Cache interface.
3650 Changes around the source tree.
3652 * Added silc_hash_table_rehash_ext to rehash with specific
3653 hash function. Affected file lib/silcutil/silchashtable.[ch].
3655 * Added silc_hash_string_compare to compare two strings in the
3656 hash table. Affected file lib/silcutil/silcutil.[ch].
3658 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Added new function silc_idcache_del_by_context into the
3661 lib/silccore/idcache.[ch].
3663 * Changed the server's ID list routines to use the new ID Cache
3664 interface. Changes around the source tree.
3666 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Added silc_hash_table_del[_by_context]_ext functions in to the
3669 lib/silcutil/silchashtable.[ch].
3671 Removed silc_hash_table_find_all* routines and added new
3672 silc_hash_table_find_foreach to replace them.
3674 Added silc_hash_table_replace_ext function as extended
3675 replacing function. Separated the simple hash table interface
3676 from the extended hash table interface in the file
3677 lib/silcutil/silchashtable.h.
3679 * Fixed minor bugs and changed it to use some of the new
3680 hash table functions in lib/silccore/idcache.c
3682 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Added new function silc_hash_table_find_all to return all keys
3685 in the hash table by the specified key. As the hash table is
3686 collision resistant it also makes it possible to have several
3687 duplicate keys in the hash table. This function may be used to
3688 find all of the keys from the hash.
3690 Added user_context arguments to the SilcHashFunction,
3691 SilcHashCompare and SilcHashDestructor to deliver user specified
3694 Added new fuctions silc_hash_table_find[_all]_ext to do
3695 extended lookup with specified hash and compare functions and
3696 specified user contexts.
3698 Added new function silc_hash_table_add_ext to add the key
3699 with specified hash function and user context.
3701 Added new function silc_hash_table_foreach to traverse all
3702 entrys in the hash table. Added SilcHashForeach callback
3705 Added new function silc_hash_table_del_by_context to delete
3706 the entry only if the context associated with the key matches.
3708 Affected files are lib/silcutil/silchashtable.[ch].
3710 * Removed silc_hash_[server/client/channel]_id and added just
3711 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3712 silc_hash_id_compare to compare two ID's using as the hash table
3713 comparison function. Added also silc_hash_data to hash
3714 binary data and silc_hash_data_compare to compare it.
3716 * Removed silc_idlist_find_client_by_hash as it is not needed
3717 anymore. Affected file silcd/idlist.[ch].
3719 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3720 to use internally the SilcHashTable. The new ID Cache is a lot
3721 faster than the old one. Some of the ID Cache interface was also
3722 rewritten and obsolete and stupid functions were removed.
3724 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added entry_count field to the SilcHashTable to keep the number
3727 of the entries in the table. Implemented the function
3728 silc_hash_table_rehash. Added new function
3729 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3731 Fixed a minor bug in silc_hash_table_free.
3733 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3734 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3735 into the lib/silcutil/silcutil.[ch].
3737 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Implemented a collision resistant hash table into the
3740 lib/silcutil/silchashtable[ch]. See the header and the source
3741 for the SilcHashTable API.
3743 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Merged dotconf version 1.0.2 into lib/dotconf.
3747 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Do not compile anything in lib/silcsim/* if the SIM support
3750 is not enabled. The tree should now compile without problems
3753 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Compiled the SILC under cygwin. Compiled and tested briefly
3756 without problems. More tests needed. The SIMs didn't compile
3759 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3761 * Fixed possible crash in silc_get_username in the
3762 lib/silcutil/silcutil.c.
3764 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Fixed a va_arg in silc/client_ops.c.
3768 * Oops, RC5 routines were named AES and caused some problems
3769 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3771 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Added new SilcIDIP structure into the lib/silccore/id.h and
3774 replaced the old `ip' fields from all SILC ID's to that type.
3775 This is a step towards IPv6 support.
3777 The silc_id_get_len takes now the ID as an extra argument.
3778 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3779 both IPv4 and IPv6 based ID's.
3781 The affected files are lib/silccore/id.[ch] and other files
3782 around the tree using these routines.
3784 * Removed the ID length arguments in server from various
3785 silc_server_send_notify_* routines -> they are not needed
3788 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Fixed memory leak in silc_encode_pem_file in the file
3791 lib/silcutil/silcutil.c.
3793 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Check minor version as well in the SKE. Affected files are
3796 silcd/protocol.c and lib/silcclient/protocol.c.
3798 * Added --identifier option to the server so that an identifier
3799 can be when creating the public key for the server. Affected
3800 file is silcd/silcd.c.
3802 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3803 lib/silccrypt/silcpkcs.c.
3805 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Register default ciphers and stuff when using -C option with
3808 the server. Affected file sildc/silcd.c.
3810 * Put back the servers public key filename format, it is better
3811 than the new one. For now, the client keys are saved with the
3812 new filename format. The affected file silc/client_ops.c.
3814 * Implemented the Cipher API for the rest of the ciphers that
3815 did not implement it or implemented it the wrong way.
3817 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Register default ciphers and stuff when using the -S option
3820 in the client. Affected file silc/silc.c. Same also when
3821 creating new key pair with -C option.
3823 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Fixed the silc_verify_public_key client operation function to
3826 save the public keys differently. The fingerprint is now
3827 used as filename and not the hostname. This way also the
3828 client keys are saved uniquely and not with hostnames. The
3829 affected file is silc/client_ops.c.
3831 * Trimmed the silc_hash_fingerprint function to remove extra
3832 whitespaces from the end of the fingerprint. The affected
3833 file is lib/silccrypt/silchash.c.
3837 * Added silc_cipher_register_default function to register all
3838 default ciphers. It can be used when configuration files
3839 does not exist and the application does not want any specific
3840 ciphers in any specific order.
3842 The SilcDList is now used as silc_cipher_list dynamically
3843 allocated cipher list. Removed the static list all together
3844 and now all ciphers must be allocated to the dynamic list.
3845 The silc_cipher_alloc routine was changed to check only the
3848 All silc_cipher_* routines that used to return int returns
3851 The affected files lib/silccrypt/silccrypt.[ch].
3853 * The same thing was done to silc_hash_* as for silc_cipher_*
3854 routines. Affected files lib/silccrypt/silchash.[ch].
3856 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3857 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3858 Added also silc_pkcs_[un]register[_default] functions.
3859 Removed the data_context from the PKCS API.
3861 * Added silc_hmac_register_default function to register default
3862 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3863 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3864 to unregister all hmacs at once.
3866 * Register the default ciphers, hash functions, PKCSs and HMACs
3867 if client's configuration file does not exist. The affected
3870 * The client did not load the hash functions from the SIM
3871 modules at all. Added support for this. Affected file is
3872 silc/clientconfig.c.
3874 * When decoding public key with silc_pkcs_public_key_decode, check
3875 the supported algorithm only if PKCS are registered. Affected
3876 file lib/silccrypt/silcpkcs.c. The same was done with the
3877 silc_pkcs_private_key_decode.
3879 * Fixed the SILC List routines to keep the list always in order.
3880 It used to change the list's order when traversing the list but
3881 not it preserves the order. Affected file lib/trq/silclist.h.
3883 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Added the client library to use the SilcSocketConnection's
3886 reference counter (by silc_socket_dup) to prevent the bug that
3887 the socket object may be freed underneath async operation.
3889 * The name resolv library checking fixes in the configure.in.pre.
3892 * Created new version of the protocol drafts for future
3893 development. The -03 drafts are the ones that will be changed
3894 in the trunk now and the -02 will remain as they are.
3896 * Send list of CUMODE notifys to the router when announcing
3897 the channel users to the router. Affected file silcd/server.c.
3898 If the router receiving channel founder CUMODE for a channel
3899 that already has channel founder it will send CUMODE notify
3900 to the sender to remove the channel founder rights from the
3901 announced client. Affected file silcd/packet_receive.c.
3903 * The CUMODE notify may now use Server ID as well as the entity
3904 who changes the mode. Updated protocool specs.
3906 * Updated INSTALL and README files.
3908 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * New web pages in the http://silc.pspt.fi. The pages was
3915 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Implemented the [DenyConnectin] config section in the server.
3918 Added silc_server_config_denied_conn to check whether incoming
3919 connection is denied. Affected file silcd/serverconfig.[ch].
3921 * Do not check the ports when checking the incoming configuration
3922 data if the port is 0, meaning any. Affected file is
3923 silcd/serverconfig.c.
3925 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Fixed buffer overflow in silc_string_compare in the file
3928 lib/silcutil/silcutil.c.
3930 * Fixed double free in silc_server_command_leave in the file
3933 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Fixed the version checking in the server. Affected file is
3938 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Fixed the configuration data fetching when accepting new
3941 connections in the server. Affected file silcd/server.c.
3943 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Added `sender_entry' argument to the function
3946 silc_server_packet_relay_to_channel so that we can check
3947 whether some destination actually belongs to the same route
3948 the sender belongs (ie, we must not resend the packet to the
3949 sender). Affected file silcd/packet_send.[ch].
3951 * Added `servername' field to the SilcClientEntry in the server
3952 to hold the name of the server where client is from. Affected
3953 file is silcd/idlist.h.
3955 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Moved the channel message encrypting in the router betwen
3958 router connections from silc_server_channel_message to the
3959 silc_server_packet_relay_to_channel since we want to check
3960 whether we have anybody channel before encrypting anything.
3961 Affected files silcd/packet_[receive/send].c.
3963 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Fixed the [AdminConnection] server config section to support
3966 multiple entries. Affected file silcd/serverconfig.c.
3968 * Added support into the server to check the validity of the
3969 incoming connection before executing any KE or authentication
3972 * The connection configuration is now saved to the KE and
3973 connection auth protocol contexts and not fetched anymore in
3974 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3976 * The local hosts listenning address and port is also resolved
3977 now when starting the server. We want to have the socket object
3978 to include the real address and port for the listener. Added
3979 new function silc_net_check_local_by_sock into the files
3980 lib/silcutil/silcnet.[ch].
3982 * Fixed a broadcast bug in server -> do not broadcast if we
3985 * Fixed a routing bug. Do not route broadcast packets ever.
3986 Broadcast packets must be processed always and not routed since
3987 they may be destined to some other host than yourself and thus
3988 would get routed without no good reason. Affected file is
3991 * Added function silc_server_config_is_primary_route to check
3992 whether primary router connection has been configured (a router
3993 configuration that we are initiating). If there is not, we
3994 will assume that there is only two routers in the SILC network
3995 and we will use the incoming router connection as our primary
3996 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3998 * Changed the order of the broadcasting. Broadcast _after_ the
3999 packet has been processed not before. Affected file is
4002 * Fixed a [ClientConnection] parsing bug. The port was never
4003 parsed correctly thus resulting to port 0. Affected file
4004 silcd/serverconfig.c.
4006 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4007 argument and did not set the broadcast packet flag. Affected
4008 file silcd/packet_send.c. Fixed same bug in the function
4009 silc_server_send_notify as well.
4011 * If we receive NEW_ID packet for our own ID in the server, ignore
4014 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Removed the nickname from the Private Message Payload.
4019 Updated the code and the protocol specs.
4021 * Updated protocol specs for submitting to the IETF.
4023 * Tweaked the Random Number Generator a bit. Affected file
4024 lib/silccrypt/silcrng.c. Exported a new function
4025 silc_rng_[global]_add_noise which can be used to add more
4028 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Do not parse packets with different timeout when protocol
4031 is active -> may cause problem with rekey. Affected file
4034 * When server receives signoff notify it must not create
4035 new channel key if the client is on any channels since the
4036 sender of the signoff notify will create it.
4038 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Added printing of error messages during SKE protocol from the
4041 failure packet sent by server during SKE. Affected file
4044 * Removed the client's failure_callback handling with timeout
4045 and handle it immediately when received.
4047 * The SKE library returned wrong type in SUCCESS and FAILURE
4048 packets. They must be 32 bit MSB not 16 bit MSB.
4050 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Ok, rewrote the logic of the re-key and now it seems to work.
4053 I tested it on high traffic with frequent re-keys without
4054 problems. Added hmac_receive (and renamed hmac to hmac_send)
4055 in SilcClientConnection in lib/silcclient/client.h and
4056 in SilcIDListData in silcd/idlist.h. Also, removed the
4057 SilcPacketParserContext's cipher and hmac fields as they are
4058 not needed anymore and actually caused some problems when
4059 the ciphers and hmac's changed underneath the packet parser.
4061 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * If re-key protocol is active then process the incoming packets
4064 synchronously since we must assure that icoming packets encrypted
4065 with the old key is processed before the new keys is set to
4066 use. This is true other packets than for REKEY packets.
4067 Affected file silcd/server.c. The same was done to client library
4068 as well, affected file lib/silcclient/client.c.
4070 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Fixed bug in client and server to accept the force send if
4073 the packet is send from silc_[server/client]_packet_process
4074 function. Otherwise the packets are never delivered, oops.
4076 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Disable force sending of packets when REKEY protocol is active.
4079 We must assure that no packet is sent directly when rekey is
4080 performed. All packets must be sent through packet queue.
4081 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4082 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4083 function is silc_[server/client]_packet_send_real to check
4086 * Replaced the SIM paths from example config files to
4087 /usr/local/modules. Also, make install creates now
4088 /usr/local/silc/logs directory to hold all the SILC server
4091 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Made the configure.in.pre work on Solaris. Patch by salo.

4096 CBC mode macros into lib/silccrypt/ciphers_def.h.
4098 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Fixed the make install.
4102 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * When MAC computation fails the silc_packet_decrypt returned 0
4105 even though it was supposed to return -1. Fixed this. The
4106 affected file is lib/silccore/silcpacket.c.
4108 * Do not replace the config files in /etc/silc (in make install)
4109 if they already exist. Affected file ./Makefile.am.
4111 * Do not send re-key packets immediately but through packet queue.
4112 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4114 * Changed silc_net_check_host_by_sock to return FALSE if the
4115 IP/DNS could not be resolved. Though, it returns the IP address
4116 now even if it could not resolve it (but returns also FALSE).
4117 Affected file lib/silcutil/silcnet.[ch].
4119 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Added silc_pkcs_decode_identifier to decode the public key's
4122 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4123 Added also silc_pkcs_free_identifier. Added also new context
4124 SilcPublicKeyIdentifier.
4126 * Added -S option to the silc client. It is used to dump the
4127 contents of the specified public key file.
4129 * Changed the PKCS api to return the public key length when
4130 setting the public key.
4132 * Fixed a fatal bug in the public and private key file loading.
4133 Affected file lib/silccrypt/silcpkcs.c.
4135 * Execute the packet parsing for client with zero (0) timeout
4136 if the protocol is active. Affected file silcd/server.c.
4138 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Made the key generation options to the silcd program. Added
4141 -C option, equivalent to client's option.
4143 * Added new [ServerKeys] config section to the server. It
4144 configures the server's public and private key.
4146 * Defined generic Public Key Payload into the protocol
4147 specification to send specific type of public keys and
4150 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4151 public key or certificate.
4153 * Implemented the GETKEY command to the server and to the
4154 client library and on user interface.
4156 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Made preliminary `make install' work.

4187 SilcClientConnection structure; not needed. Affected file is
4188 lib/silcclient/client.h.
4192 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Do not ask whether user wants to use the negotiated private key
4195 for private messages, just use it. Affected file is
4196 silc/local_command.c.
4198 * Added `send_enc_key' and `enc_key_len' fields to the
4199 SilcIDListData structure since they are needed in the re-key

4219 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4220 int64 of at least the xintXX size. If void * is less that 4
4221 bytes uint32 * will be used. Defined bool as boolean.
4223 * Changed _ALL_ unsigned long and unsigned int to uint32,
4224 unsgined short to uint16 in the source tree.
4226 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4227 not handle clients that has entry->data.registered == FALSE.
4228 They are not in the network anymore. Affected file is
4231 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * Implemented the sending of the SERVER_SIGNOFF notify in the
4234 server. Affected file is silcd/server.c.
4236 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

4249 if the deleting was successful. Affected file silcd/idlist.[ch].
4251 * Added support for public key authentication in the connection
4252 authentication protocol in the client library. Affected file
4253 lib/silcclient/protocol.c.
4255 * Changed the server's silc_idlist_get_clients_by_* interface
4256 to support already allocated array so that new entries may be

4258 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4259 and command replies.
4261 * All command reply functions in the server now calls the
4262 pending command callback even if error occured. This way the
4263 error will be delivered to the client as well. Affected files
4264 silcd/command.c and silcd/command_reply.c.
4266 * Fixed INFO command to return local server's info if no server
4267 was provided. Affected file lib/silcclient/command.c.
4269 * Removed RESTART command for good. Updated the code and the
4272 * Rewrote parts of the task system. It is a bit simpler now.
4273 Removed unsued task priorities. The affected files are
4274 lib/silcutil/silctask.[ch].
4276 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Moved the USERS printing from the library to the application.
4279 Affected files lib/silcclient/command.c and silc/client_ops.c.
4281 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added channel key re-key support. The re-key is perfomed
4286 only by the router and is done once in an hour. Added `rekey'
4287 field to the SilcChannelEntry in the server. Affected files
4288 silcd/server.c and silcd/idlist.h.
4290 * Added silc_task_unregister_by_context into the file
4291 lib/silcutil/silctask.[ch].
4293 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Added SILC_UMODE_GONE mode to indicate when the client is not
4296 present in the SILC network. Added also support to the local
4297 command AWAY that will set this mode. Added support of showing
4298 "xxx is gone" in WHOIS command. The USERS command shows the
4299 gone status as well.
4301 * Fixed setting server and router operator privileges in the
4302 server's UMODE command. Affected file silcd/command.c.
4304 * Merged the SKE KE1 and KE2 payloads into one payload. The
4305 new KE payload is equivalent to the old KE2 payload.
4307 Cleaned up the SKE Start Payload parsing. It now uses the
4308 simple buffer unformatting to do the parsing. A lot faster
4311 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4312 to the SKE that is used to indicate whether both of the SKE
4313 parties should perform authentication. By default only the
4314 responder performs authentication. By setting this flag also
4315 the initiator must do authentication. By default it is unset
4316 since in normal SKE case, client to server connection, only
4317 the responder should do authentication. When doing SKE between
4318 two clients both should perform authentication. Updated the
4319 code and the protocol specs.
4321 * A little fix to IDENTIFY command in the server. Search the
4322 client first by hash not nickname. Affected file is
4325 * Fixed the silc_client_close_connection to support closing
4326 the client to client connections wihtout deleting too much
4327 data. Affected file lib/silcclient/client.c.
4329 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4330 are received if protocol used to be active but is not anymore
4331 the application would crash due to NULL pointer dereference.
4332 Affected files silcd/server.c and lib/silcclient/client.c.
4334 * Added `hash' field to the SilcClientConnection to include
4335 the hash function negotiated in the SKE protocol.
4337 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4338 to set the channel founder authentication data. A client can
4339 claim the founder rights later by providing the authentication
4340 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4341 This way the channel founder can regain the channel founder
4342 privileges even it is left the channel. This works only on
4343 local server and the client must be connected to the same
4344 server to be able to regain the founder rights. Updated the
4345 protocol specs accordingly.
4347 Added support to the CMODE command in the client to set the
4348 founder auth data. Read the README to see how to set it.
4350 Added support to the CUMODE command to claim the founder
4351 rights. Read the README to see how to do it.
4353 Added support for the founder authentication to the Channel
4354 Entry in the server. Affected file silcd/idlist.h.
4356 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4357 server's CMODE command. Affected file silcd/command.c.
4359 * Added the following new functions into lib/silccore/silcauth.[ch]:
4360 silc_auth_get_method and silc_auth_get_data.
4362 * The server now saves the remote hosts public key to the
4363 SilcIDListData pointer. Affected file silcd/protocol.c.
4365 * The normal server now does not remove the channel entry from
4366 the cache if the founder authentication data is set. It used
4367 to remove it if the founder was the last one on the channel on
4368 the server and left the channel. The auth data is saved and
4369 if the channel is re-joined later the old entry is used with
4370 the old auth data. Affected files silcd/command_reply.c and
4373 * Removed the `pkcs' field from the SilcIDListData structure
4374 in the server; it is not used. Affected file silcd/idlist.h.
4376 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Fixed packet processing on slow links. Partial packets were
4379 never re-processed because the incoming data buffer was cleared
4380 by the application. Application must not directly clear the
4381 sock->inbuf, the packet processing routines handle it. Fixed
4382 this in client library and in server.
4384 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Fixed the WHOIS and IDENTIFY send reply function to really
4387 check whether to send list or just one entry. Affected file
4390 * Cleaned up the LEAVE command's channel key distribution. The
4391 affected file silcd/command.c.
4393 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4394 can enforce the channel mode as well. In that case the ID
4395 includes the ID of the server. The code now enforces the
4396 mode change if the router have different mode than the server.
4398 * The notify client operation with CMODE_CHANGE notify can now
4399 return NULL client_entry pointer if the CMODE was not changed
4400 by client. Application must check for this.
4402 * Added <Server ID> argument to INFO command to support server
4403 info fetching by Server ID.
4405 * Added silc_server_announce_get_channel_users to get assembled
4406 packets of channel users of the specified channel. Affected
4407 file silcd/server.[ch].
4409 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4410 was freed underneath the ID Cache.
4412 * Re-announce clients when the server received CHANNEL_CHANGE
4413 notify from the router. Affected file silcd/packet_send.c.
4415 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4418 crashed since it did not handle the fact that there is no cipher
4419 called "3" and didn't check the error condition. Now fixed.
4421 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4422 flag. It can be used to send message requests.
4424 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Implemented the RESTART command in the client.
4428 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4429 notice type messages. Added notice printing to the user
4432 * The channel keys are not re-generated if the channel's mode
4433 is PRIVKEY, ie private key on the channel exists. Affected
4434 files silcd/server.c and silcd/command.c.
4436 * Fixed a little bug in channel message delivery when channel
4437 private keys are set in the server. Affected file is
4438 silcd/packet_send.c.
4440 * Changed the setting on channel->on_channel = TRUE from the
4441 silc_client_save_channel_key to the JOIN command reply. The
4442 key payload is not received if the private channel key is set.
4443 Affected file lib/silcclient/command_reply.c and the
4444 lib/silcclient/client_channel.c.
4446 * When the CMODE_CHANGE notify is sent and the channel private
4447 key mode is removed the channel key must be re-generated in
4448 other cells as well. Added this support for the router in the
4449 silcd/packet_receive.c.
4451 * Added new local command NOTICE to send notice message on
4452 channel. Affected file silc/local_command.[ch].
4454 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Added new local command ME to the client. It is used to send
4457 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4458 some action. Affected file silc/local_command.[ch].
4460 * Changed channel_message and private_message client operations
4461 to deliver the message flags to the application. Added also
4462 the `flags' arguments to the silc_client_send_channel_message
4463 and silc_client_send_private_message functions. Affected file
4466 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Redefined the Private Message Payload to support private message
4469 keys and to support the new private message flags. Updated
4470 the protocol specs. Flags makes it possible to have for example
4471 CTCP style messages.
4473 * Added new type SilcPrivateMessagePayload and defined an API
4474 for it in the lib/silcclient/silcprivate.[ch].
4476 * Tested private message private keys successfully. Tested the
4477 private message key set, unset and list commands with the new
4480 * Redefined the Channel Message Payload to include the channel
4481 message flags (equal with private message flags) to support
4482 for example CTCP style messages.
4484 * Defined some of the message (for channel and private message)
4485 flags. Updated the protocol specs and added the flags to the
4486 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4488 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Added SilcKeyAgreementStatus type to the key agreement routines
4491 to indicate the current status and error if one occured.
4492 The status types are defined in the lib/silcclient/silcapi.h.
4494 * Added new local command KEY that is used to set and unset private
4495 keys for channels, set and unset private keys for private messages
4496 with remote clients and to send key agreement requests and
4497 negotiate the key agreement protocol with remote client. The
4498 key agreement is supported only to negotiate private message keys,
4499 it currently cannot be used to negotiate private keys for channels,
4500 as it is not convenient for that purpose.
4502 * Fixed a minor pending callback setting bug in the function
4503 silc_client_get_client_by_id_resolve, now the function works.
4504 Affected file lib/silcclient/idlist.c.
4506 * Added function silc_net_get_local_port to get local bound
4507 port by socket. Added to lib/silcutil/silcnet.[ch].
4509 * Added `sockets' and `sockets_count' fields to the SilcClient
4510 object. They hold the sockets of the listenning sockets in
4511 the client. Listenning sockets may be for example the key
4512 agreement server. Affected file lib/silcclient/client.[ch].
4513 Added functions the silc_client_add_socket and the
4514 silc_client_del_socket. They are exported to the application
4517 * Added ~./silc/clientkeys to support other client's public keys.
4519 * Renamed verify_server_key client operation to verify_public_key
4520 and added one argument to indicate the type of the connection
4521 (server, client etc.).
4523 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Added silc_server_connection_auth_request to handle the
4526 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4527 silcd/packet_receive.[ch].
4529 * Added silc_server_send_connection_auth_request into the
4530 silcd/packet_send.c to send the connection auth request packet.
4532 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4535 * Fixed the public key authentication in responder side in the
4536 server. The `auth_data' pointer includes the SilcPublicKey
4537 not the path to the public key. Affected file silcd/protocol.c.
4539 * Implemented the public key authentication in the initiator side
4540 in the server. Affected file silcd/protocol.c.
4542 * Removed the [RedirectClient] config section from the server
4543 configuration. Is not needed and I don't want to implement it.
4545 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Cleaned up the CMODE command in the server. It now works
4548 correctly and supports all the modes defined in the protocol.
4549 Affected file is silcd/command.c.
4551 * Added `hmac_name' field to the SilcChannelEntry in the server
4552 to hold the default HMAC of the channel. It can be set when
4553 creating the channel (with JOIN command). Affected files
4556 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4557 type to indicate the change of the current cipher and hmac
4558 on the channel. Client can safely ignore the <cipher> argument
4559 (if it chooses to do so) since the CHANNEL_KEY packet will
4560 force the channel key change anyway. The <hmac> argument is
4561 important since the client is responsible of setting the new
4562 HMAC and the hmac key into use.
4564 * Fixed the CMODE command in the client library as well.
4566 * Tested CMODE command in router environment successfully.
4568 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Show the version of the remote client (or server) when connecting
4571 to the server. It is logged to the log file. Affected file
4572 is silcd/protocol.c.
4574 * Fixed the KILLED notify handling in the client library. The
4575 client must be removed from all channels when receiving the
4578 Also, do not remove the client entry when giving the KILL
4579 command but when the KILLED notify is received.
4581 * Removed silc_idlist_find_client_by_nickname from the server.
4582 Not needed anymore. Affected files silcd/idlist.[ch].
4584 * Implemented the CHANNEL_CHANGE notify type handling to the
4585 server. Affected file silcd/server.c.
4589 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Added silc_server_send_notify_invite to send the INVITE
4592 notify between routers.
4594 * Implemented the INVITE command correctly to the server.
4596 * Implemented the INVITE notify type handling in the server.
4598 * Implemented the INVITE command to the client library and on the
4601 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Added function silc_server_get_client_resolve to find the
4604 client entry by ID from all ID lists and then resolve it
4605 (using WHOIS) if it cannot be found. Affected file is
4608 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Implemented the BAN command to the client library.
4612 * The JOIN command in the server now checks the invite list
4615 * Changed the silc_command_reply_payload_encode_va and the
4616 silc_command_payload_encode_va to support that if argument is
4617 NULL it ignores and checks the next argument. Affected file
4618 lib/silccore/silccommand.c.
4620 * Added silc_server_send_notify_ban to send the BAN notify
4621 type between routers.
4623 * Chaned the silc_notify_payload_encode to support that if
4624 argument is NULL it ignores and checks the next argument.
4625 Affected file lib/silccore/silcnotify.c.
4627 * Tested ban lists in router environment successfully.
4629 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Implemented BAN command to the server, in silcd/command.[ch].
4633 * Removed the BAN and INVITE_LIST modes from the CMODE command
4636 * Added function silc_string_match to regex match two strings.
4637 Affected files lib/silcutil/silcutil.[ch].
4639 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Redefined parts of the SilcChannelEntry in the server to support
4642 the new ban and invite lists.
4644 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Redefined the INVITE command. The same command can be used to
4647 invite individuals to the channel but also to manage the invite
4648 list of the channel (to add to and remove from the invite list).
4649 Updated the protocol specs.
4651 * Added new command SILC_COMMAND_BAN that can be used to manage
4652 the ban list of the channel. Updated the protocol specs.
4654 * Removed the channel modes: the SILC_CMODE_BAN and the
4655 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4656 in the CMODE command. The equivalent features are now available
4657 using INVITE and BAN commands. Updated the protocol specs.
4659 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4660 in the network about change in the current ban list. The notify
4661 type is not used by the client.
4663 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4664 support the invite lists.
4666 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Added new function silc_string_regexify that converts string
4669 including wildcard characters into regex string that can
4670 be used by the GNU regex library. Added into the file
4671 lib/silcutil/silcutil.[ch].
4673 Added silc_string_regex_combine to combine to regex strings
4674 into one so that they can be used as one regex string by
4675 the GNU regex library. Added into the file
4676 lib/silcutil/silcutil.[ch].
4678 Added silc_string_regex_match to match two strings. It returns
4679 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4681 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Imported GNU regex to the soruce tree into lib/contrib.
4684 Fixed some compiler warning from the regex.c.
4686 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Fixed MOTD command in the server to work in router environment.
4690 * Fixed the MOTD command in the client library to support
4691 the server argument in the command.
4693 * Added `nickname_len' argument to the silc_idlist_add_client
4694 in the server, as the `nickname' argument may be binary data
4697 * Added silc_idlist_get_channels to return all channels from
4700 * Implemented LIST command to the server. Affected file is
4703 * Implemented the LIST command to the client library and on the
4706 * Added [<user count>] argument to the LIST command reply.
4707 With private channels the user count is not shown.
4709 * Updated TODO and README.
4711 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * The client entry's data.registered must be TRUE even with
4714 global client entry on global client list. The data.registered
4715 is used to check whether the client is anymore in the network,
4716 for example with WHOWAS command so it must be valid.
4718 * Fixed the WHOWAS command in the server. It now actually works
4719 in router environment. Added function into silcd/command_reply.c
4720 silc_server_command_reply_whowas_save.
4722 * Added silc_idlist_purge function to the silcd/idlist.c
4723 to periodically purge the ID Cache.
4725 * Fixed INFO command in the server. It works now in router
4726 environment. Added <server name> argument to the INFO command
4727 reply. Updated the protocol specs.
4729 * Fixed minor bug in silc_idcache_purge to not purge if the
4730 expire value is zero.
4732 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4733 they were buggy because of the WHOWAS information.
4735 * Fixed local command MSG to handle the async resolving of
4736 the remote client properly. It used to fail the first MSG.
4737 Affected file silc/local_command.c.
4739 * Added `data_len' field to SilcIDCache context.
4741 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Update TODO. Todo in commands in the server.
4745 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4748 used by routers as broadcast packet to inform other routers
4749 about the changed user mode.
4751 Implemented the notify handling in the server. Affected file is
4752 silcd/packet_receive.c. Added the function
4753 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4755 * Added new generic Channel Payload and deprecated the New Channel
4756 Payload. The New Channel Payload is now the generic Channel
4759 * Added new argument `mode' to the silc_server_send_new_channel
4760 as it is required in the Channel Payload now.
4762 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4763 and created a new and real SilChannelPayload to represent the
4764 new generic Channel Payload. Implemented the encode/decode
4765 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4767 * Added silc_server_get_client_channel_list to return the list
4768 of channels the client has joined for WHOIS command reply.
4769 Affected file silcd/server.[ch].
4771 * Implemented the channel list sending in the WHOIS command reply
4772 in server and in the client.
4774 Implemented the channel list displaying on the user interface
4775 as well. Affected file silc/client_ops.c.
4777 * Added silc_channel_payload_parse_list to parse list of Channel
4778 Payloads. It returns SilcDList list of SilcChannelPayloads.
4779 Client for example can use this function to parse the list of
4780 channels it receives in the WHOIS command reply. The caller
4781 must free the list by calling silc_channel_payload_list_free.
4782 Affected files lib/silccore/silcchannel.[ch].
4784 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Added one new argument <user mode> to the WHOIS command reply
4787 to return the mode of the user in SILC. Updated the protocol
4790 Implemented it to the server and client.
4792 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Fixed the mode printing on the user interface on joining.
4795 Affected file silc/client_ops.c.
4797 * Implemented the UMODE command and user modes in general to the
4798 client library and to the user interface.
4800 * Implemented the UMODE command to the server.
4802 * The server now sends UNKNOWN_COMMAND error status if client sends
4803 unknown command. Affected file silcd/command.c.
4805 * All server commands now handle the command identifier the right
4806 way when sending the command reply to the client. The client can
4807 use to identify the command replies with the identifier.
4809 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added silc_server_get_client_route to resolve the route to
4812 the client indicated by the client ID. Affected file is
4815 * Added silc_server_relay_packet as general function to relay
4816 packet to arbitrary destination. This deprecates functions
4817 like _send_private_message_key, _relay_notify etc. Affected
4818 file is silcd/packet_send.[ch].
4820 Removed silc_server_send_key_agreement,
4821 silc_server_send_private_message_key and
4822 silc_server_packet_relay_notify functions from the file
4823 silcd/packet_send.[ch].
4827 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4828 server. Affected file silcd/packet_receive.[ch].
4830 * Implemented the KILL command to the client. Implemented the
4831 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4832 Affected files lib/silcclient/command[_reply].c and
4833 lib/silcclient/client_notify.c. Implemented the KILL notify
4834 printing in the user inteface.
4836 * Fixed a lot silc_parse_nick memory leaks from the client
4837 library in the file lib/silcclient/command.c.
4839 * Changed the silc_server_send_notify_on_channels's `sender'
4840 argument from SilcSocketConnection to SilcClientEntry to
4841 check the sender as entry and not as connection object and not
4842 to send to the client provided as argument. The affected file
4843 is silcd/packet_send.[ch].
4845 * The notify packets that are destined directly to the client used
4846 to not to be processed by the server. Now changed that and the
4847 server processes all notify packets. After relaying the packet
4848 to the client the notify packet is processed in the server.
4850 * The silc_server_free_client_data now checks whether there is
4851 pending outgoing traffic for the client and purges the data to
4852 the network before removing the client entry.
4854 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4857 an client is killed from the SILC Network. Updated the protocol
4860 Added new function silc_server_send_notify_killed to the
4861 silcd/packet_send.[ch].
4863 * Added function silc_server_packet_relay_notify to relay notify
4864 packets that are destined directly to a client. In this case
4865 the server does not process the notify packets but merely relays
4866 it to the client. Affected file silcd/packet_send.[ch].
4868 Added also silc_server_packet_process_relay_notify to check
4869 whereto relay the notify. Affected file is
4870 silcd/packet_receive.[ch].
4872 * Implemented the KILL command to the server.
4876 * Added the backup schema desgined last fall to the protocol
4877 specs for everyone to see. The specification is in the
4878 *-spec-xx.txt draft and the packet type definitions for the
4879 backup routers is in *-pp-xx.txt draft. Thusly, added also
4880 new packet type SILC_PACKET_CELL_ROUTERS.
4882 * A big security problem in the implementation discovered. The
4883 signoff of an client did not cause new channel key generation
4884 which it of course should've done. The channel keys must be
4885 always re-generated when client leaves (or signoffs) the channel.
4886 The silc_server_remove_from_channels funtion now handles
4887 the channel key re-generation.
4889 * Added `sender' argument to the silc_server_send_notify_on_channels
4890 to not to send the client provided as argument. Affected file
4891 silcd/packet_send.[ch].
4893 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Implemented OPER and SILCOPER commands into the server and
4898 * Added silc_auth_verify and silc_auth_verify_data to verify
4899 the authentication directly from the authentication payload.
4900 It supports verifying both passphrase and public key based
4901 authentication. Affected file lib/silccore/silcauth.[ch].
4903 * Added `hash' field to the SilcIDListData structure. It is the
4904 hash negotiated in the SKE protocol. Affected file is
4907 * Slight redesigning of the SilcAuthPayload handling routines.
4908 Do not send SilcPKCS but SilcPublicKey as argument.
4910 * Implemented the public key authentication support to the
4911 serverconfig. The public key is loaded from the provided path
4912 and saved as authentication data to void * pointer. Thus,
4913 changed the unsigned char *auth_data to void *auth_data;
4915 * Fixed SHUTDOWN command to send the reply before the server
4916 is shutdown. :) Affected file silcd/command.c.
4918 * Fixed fatal bug in CONNECT command. The hostname was invalid
4919 memory and server crashed. Affected file silcd/command.c.
4921 * Fixed fatal bug in CLOSE command. The server_entry became
4922 invalid but was referenced later in the command. Affected file
4925 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Fixed fatal bug in failure packet handling. Server ignored
4928 the failure and thus crashed when it came.
4932 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4935 that the command may be executed only once in (about) 2 seconds.
4936 The old SILC_CF_LAG flag is same but allows command bursts up
4937 to five before limiting.
4939 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4940 server code. Various commands now includes the CF_LAG_STRICT
4941 flag to disallow any kind of miss-use of the command.
4943 * Fixed the silc_buffer_unformat to not to allocate any data
4944 if the length of the data is zero. It used to allocate the
4945 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4947 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Changed the format of AdminConnection configuration section
4950 in the server. Added username of the admin to the format.
4951 Affected files silcd/serverconfig.[ch].
4953 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4954 to return admin configuration data by host, username and/or
4957 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Implemented WHOWAS command to the server. Added the functions:
4961 silc_server_command_whowas_parse,
4962 silc_server_command_whowas_send_reply,
4963 silc_server_command_whowas_from_client and
4964 silc_server_command_whowas_from_server
4966 * Added <Client ID> argument to the WHOWAS command reply. Updated
4967 the protocol specs accordingly.
4969 * Implemented WHOWAS command and command_reply to the client
4972 Implemented the WHOWAS printing on the user interface.
4974 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Added new argument to the WHOWAS command reply, the real name.
4977 It is an optional argument. Updated the protocol specs.
4979 * Added SilcIDCacheDestructor callback that is registered when
4980 the SilcIDCache is allocated. The callback is called when
4981 an cache entry in the ID Cache expires, or is purged from the
4982 cache. Added into lib/silccore/idcache.[ch].
4984 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4985 to destruct the client entries when the cache entry expires.
4986 Other ID Cache's in server and in the client library ignores
4989 * If the ID Cache entry's `expire' field is zero then the entry
4990 never expires. Added boolean `expire' argument to the
4991 silc_idcache_add function in the lib/silccore/idcache.[ch].
4992 If it is TRUE the default expiry value is used.
4994 * Added silc_server_free_client_data_timeout that is registered
4995 when client disconnects. By default for 5 minutes we preserve
4996 the client entry for history - for WHOWAS command.
4998 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Added support to the server to enforce that commands are not
5001 executed more than once in 2 seconds. If server receives
5002 commands from client more frequently, timeout is registered
5003 to process the commands. Affected file silcd/command.c.
5004 Added new function silc_server_command_process_timeout.
5006 * Changed NICK_NOTIFY handling in client library to check that
5007 if the client's nickname was changed, so there is no need to
5008 resolve anything from the server.
5010 * Removed error printing from the WHOIS and IDENTIFY commands.
5011 If error occurs then it is ignored silently in the client library.
5012 The application, however, may map the received error to
5013 human readable error string. The application currently maps
5014 the NO_SUCH_NICKNAME error to string.
5016 * Made the command status message public to the application. Moved
5017 them from lib/silcclient/command_reply.c to
5018 lib/silcclient/command_reply.h. The application can map the
5019 received command status to the string with the
5020 silc_client_command_status_message function.
5022 * Added check to the server to check that client's ID is same
5023 as the Source ID in the packet the client sent. They must
5026 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5028 * Added dist-bzip hook to the Makefile.am to make bzip2
5029 compressed distributions.
5031 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Server now enforces the maximum length for the nickname and
5034 the channel as protocol specification dictates. 128 bytes for
5035 nickname and 256 bytes for channel name.
5037 * Moved the WHOIS printing to the application. The client libary
5038 does not print out the WHOIS information anymore, the application
5039 must do it. Renamed silc_client_command_reply_whois_print to
5040 the silc_client_command_reply_whois_save.
5042 The client's idle time is also sent to the application now, and
5043 the idle is shown on screen.
5045 * Added silc_client_command_reply_identify_save to save the
5046 received IDENTIFY entries.
5048 * Do not check for channel private keys in message sending and
5049 reception if the channel does not have the PRIVKEY mode set.
5050 Affected file lib/silclient/client_channel.c.
5052 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5055 just surfaced after chaning the JOIN procedure.
5057 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Added silc_client_get_clients_by_list to get client entries
5060 from Client ID list, that is returned for example by JOIN
5061 and USERS command replies. The application should use this
5062 function for example when JOIN command reply is received to
5063 resolve the clients already on the channel (library does not
5064 do that anymore as USERS command reply is not used in the JOIN
5065 procedure anymore). Affected files lib/silcclient/silcapi.h and
5066 lib/silcclient/idlist.c.
5068 * JOIN command reply and USERS command reply returns now SilcBuffer
5069 pointers instead of unsigned char pointers when returning
5070 the client list and mode list.
5072 * Added <Client ID> argument to the JOIN command reply, mainly
5073 for the server to identify for which client the command was
5074 originally sent. Updated protocol specs accordingly.
5076 * Added SilcDlist private_key pointer to the SilcChannelEntry
5077 in the client to support the channel private keys. Affected
5078 file is lib/silcclient/idlist.h.
5080 * Added SilcChannelPrivateKey argument to the function
5081 silc_client_send_channel_message so that application can choose
5082 to use specific private ke if it wants to. If it is not provided,
5083 the normal channel key is used, unless private keys are set.
5084 In this case the first (key that was added first) is used
5085 as the encryption key.
5087 * Implemented the support for channel private key handling.
5088 Implemented the following functions:
5090 silc_client_add_channel_private_key,
5091 silc_client_del_channel_private_keys,
5092 silc_client_del_channel_private_key,
5093 silc_client_list_channel_private_keys and
5094 silc_client_free_channel_private_keys
5096 Affected file lib/silcclient/client_channel.c.
5098 * Added the support for the private keys in the channel message
5099 sending and encryption and in the message reception and
5100 decryption. Affected funtions are
5101 silc_client_send_channel_message and silc_client_channel_message.
5103 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Added SKE's key verify callback to the client library's
5106 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5108 * Removed the statement that server (or router) must send USERS
5109 command reply when joining to the channel so that the client
5110 knows who are on the channel. Instead, the client list and
5111 client's mode list is now sent in the JOIN command reply to the
5112 client who joined channel. This is better solution.
5114 * Added function silc_server_get_users_on_channel and function
5115 silc_server_save_users_on_channel to the silcd/server.[ch].
5117 * Removed function silc_server_command_send_users from the
5120 * Do not show topic on the client library anymore. The topic is
5121 sent in the command reply notify to the application and the
5122 application must show the topic now.
5124 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Added client searching by nickname hash into the IDENTIFY and
5127 WHOIS commands in the server as they were clearly missing from
5128 them. Affected file is silcd/command.c.
5130 * Fixed a bug in private message receiving in the client library.
5131 The remote ID was freed and it wasn't supposed, now it is
5134 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Minor fix to the channel payload; allocate the data area, as it
5137 needs to be of specific length.
5139 * If the key agreement port is zero then the operating
5140 system will define the bound port. Affected files are
5141 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5143 * Added new function silc_channel_payload_decrypt into the file
5144 lib/silccore/silcchannel.[ch].
5146 * Moved the channel message etc, check from silc_packet_decrypt
5147 to applications. The library calls now a generic
5148 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5149 when the packet is either normal or special. This was done to
5150 allow more wide range of checking that was not allowed when
5151 the code was in library. Now applications can do virtually any
5152 checks to the packet and return to the library the decision how
5153 the packet should be processed. Affected files are
5154 lib/silccore/silcpacket.[ch].
5156 Added silc_server_packet_decrypt_check to the server and
5157 silc_client_packet_decrypt_check to the client library.
5159 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5160 to send with specified source and destination information.
5162 * Channel message delivery between routers was broken after the
5163 channel key distribution was fixed earlier. The channel key
5164 was used be to distributed to other routers as well which is not
5165 allowed by the protocol. Now this is fixed and channel keys
5166 really are cell specific and the channel message delivery between
5167 routers comply with the protocol specification.
5169 * Fixed various commands in server to check also the global list
5170 for the channel entry and not just the local list. The affected
5171 file silcd/command.c.
5173 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Added assert()s to buffer formatting and unformatting routines
5176 to assert (if --enable-debug) when error occurs. Affected
5177 file: lib/silcutil/silcbuffmt.c.
5179 * Changed to auto-reconnect to check whether the remote host is
5180 router and register the re-connect timeout if it is. It used
5181 to check that whether we are normal server, but router must do
5182 auto-reconnect with another router as well. Affected file
5185 * Removed the [<key len>] option from CMODE command as the cipher
5186 name decides the key length, nowadays. See the defined ciphers
5187 from the protocol specification.
5189 * Added [<hmac>] option to the CMODE command to define the HMAC
5190 for the channel. Added SILC_CMODE_HMAC channel mode.
5192 * Added [<hmac>] option for the JOIN command so that user can
5193 select which HMAC is used to compute the MACs of the channel
5196 * Added Hmac field to the Channel Message Payload. The integrity
5197 of plaintext channel messages are now protected by computing
5198 MAC of the message and attaching the MAC to the payload. The
5199 MAC is encrypted. Now, it is clear that this causes some
5200 overhead to the size of the packet but rationale for this is that
5201 now the receiver can verify whether the channel message decrypted
5202 correctly and also when private keys are set for the channel the
5203 receiver can decrypt the packet with several keys and check from
5204 the MAC which key decrypted the message correctly.
5206 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5207 lib/silccrypt/silccipher.[ch].
5209 * Added silc_hash_len to return the digest length into the
5210 lib/silcrypt/silchash.[ch].
5212 * Rewrote parts of Silc Channel Payload interface in the
5213 lib/silccore/silcchannel.[ch]. The encode function now also
5214 encrypts the packet and parse function decrypts it.
5216 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Fixed a minor formatting bug in the SKE's key material processing.
5219 It actually might have processed the keys wrong way resulting
5222 * Redefined the mandatory HMAC algorithms and added new algorithms.
5223 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5224 and hmac-md5 truncated to 96 bits. The mandatory is now
5225 hmac-sha1-96. Rest are optional (including the one that used
5226 to be mandatory). Rationale for this is that the truncated HMAC
5227 length is sufficient from security point of view and can actually
5228 make the attack against the HMAC harder. Also, the truncated
5229 HMAC causes less overhead to the packets. See the RFC2104 for
5232 * Added new [hmac] configuration section. The SKE used to use
5233 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5234 is of course wrong. The official names that must be proposed in
5235 the SKE are the ones defined in the protocol specification
5236 (hmac-sha1-96 for example). The user can configure any hmac
5237 using any hash function configured in the [hash] section. At
5238 least, the mandatory must be configured.
5240 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5242 * Added HMAC list to the SKE proposal list. It has now both
5243 hash algorithm list and HMAC list. This makes the protocol
5244 incompatible with previous versions. The SKE now seems to work
5245 the way it is supposed to work, for the first time actually.
5247 * Defined plain Hash algorithms to the protocol specification.
5250 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Implemented support for key agreement packets into the server.
5253 Added functions silc_server_key_agreement and
5254 silc_server_send_key_agreement. Other than these functions,
5255 server has nothing to do with this packet.
5257 * Added support for private message key packets into the server.
5258 Added functions silc_server_private_message_key and
5259 silc_server_send_private_message_key.
5263 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5264 called in the protocol's final callback instead in the END
5265 protocol state. This makes a little more sense and in the same
5266 time in client we can use the same protocol routines for normal
5267 key exchange and to key agreement packet handling as well.
5269 * Added to both client's and server's KE protocol context the
5270 SilcSKEKeyMaterial pointer to save the key material. We will
5271 bring the key material to the protocol's final callback by doing
5272 this. The final callback must free the key material.
5274 * Added SKE's packet_send callback into client's KE protocol
5275 context so that the caller can choose what packet sending function
5276 is used. This way we can use different packet sending when
5277 doing normal SKE when doing key agreement packet handling (in
5278 the key agreement packet handling we do not want to encrypt
5281 * Implemented the responder side of the key agreement routines
5282 in the client. The client can now bind to specified port and
5283 accept incoming key negotiation. The key material is passed
5284 to the application after the protocol is over.
5286 * Implemented the processing of incoming Key Agreement packet
5287 in the client. Added function silc_client_key_agreement to
5290 * Implemented the intiator side of the key agreement routines
5291 in the client. The client can now initiate key agreement with
5292 another remote client. The key material is passed to the
5293 application after the protocol is over.
5295 * Created client_keyagr.c to include all the key agreement
5298 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5299 SILC_TASK_CALLBACK except that it is not static.
5301 * Created client_notify.c and moved the Notify packet handling
5302 from the client.[ch] into that file.
5304 * Created client_prvmsg.c and moved all private message and
5305 private message key routines from the client.[ch] into that file.
5307 * Create client_channel.c and moved all channel message and
5308 channel private key routines from the client.[ch] into that file.
5310 * Changed silc_client_get_client_by_id_resolve to resolve with
5311 WHOIS command instead of IDENTIFY command, in the file
5312 lib/silclient/idlist.c.
5314 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Implemented the SKE's responder side to the Client library.
5318 * When FAILURE is received to the protocol do not trust it
5319 blindly. Register a timeout to wait whether the remote closes
5320 the connection as it should do it, only after that process the
5321 actual failure. This was changed to both client and server.
5323 * Added client_internal.h to include some of the structures
5324 there instead of client.h in lib/silcclient/.
5326 * Added function silc_task_unregister_by_callback to unregister
5327 timeouts by the callback function.
5329 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Some "Incomplete WHOIS info" errors has been appearing on the
5332 log files. Took away the entry->userinfo check from WHOIS
5333 reply sending. The entry->userinfo is now " " if client did not
5334 provide one. I thought this was fixed earlier but something
5335 is wrong still. Let's see if the error still appears.
5337 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Fixed a minor bug in the login when the channel key is
5340 re-generated in the server. It used to generate the key in
5341 wrong order and thus caused problems in the channel traffic.
5343 * Fixed a minor bug in channel key distsribution after
5344 KICK command. The key was not sent to the router even though
5347 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Added silc_ske_process_key_material_data as generic routine
5350 to process any key material as the SILC protocol dictates. The
5351 function is used by the actual SKE library but can be used by
5352 applications as well. This relates to the private message keys
5353 and the channel private keys since they must be processed the
5354 same way the normal SILC session keys. The protocol dictates
5355 this. Affected files: lib/silcske/silcske.[ch].
5357 Added also silc_ske_free_key_material to free the
5358 SilcSKEKeyMaterial structure.
5360 * Defined silc_cipher_set_key function to set the key for
5361 cipher without using the object's method function. The affected
5362 files: lib/silccrypt/silccipher.[ch].
5364 * Implemented silc silc_client_add_private_message_key,
5365 silc_client_add_private_message_key_ske,
5366 silc_client_del_private_message_key,
5367 silc_client_list_private_message_keys and
5368 silc_client_free_private_message_keys functions in the
5371 Added functions silc_client_send_private_message_key to send
5372 the Private Message Key payload and silc_client_private_message_key
5373 to handle incoming Private Message Key payload.
5375 * Added Cipher field to the Private Message Key payload to set
5376 the cipher to be used. If ignored, the default cipher defined
5377 in the SILC protocol (aes-256-cbc) is used.
5379 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Removed lib/silcclient/ops.h file.
5383 Redefined parts of the SILC Client Library API. Created new
5384 file silcapi.h that deprecates the ops.h file and defines the
5385 published Client Library API. Defined also private message key
5386 API and channel private key API into the file.
5388 This is the file that the application must include from the
5389 SILC Client Library. Other files need not be included by
5390 the application anymore.
5392 * Added new key_agreement client operation callback and also
5393 defined the Key Agreement library API for the application.
5395 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5398 is used by clients to request key negotiation between another
5399 client in the SILC network. If the negotiation is started it
5400 is performed using the SKE protocol. The result of the
5401 negotiation, the secret key material, can be used for example
5402 as private message key.
5404 Implemented the Key Agreement payload into the files
5405 lib/silccore/silauth.[ch].
5407 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Redefined ciphers for the SILC protocol. Added some new ciphers
5410 and defined the key lengths for the algorithms. Changed the
5411 code accordingly. The default key length is now 256 bits.
5413 * Fixed SKE key distribution function silc_ske_process_key_material
5414 when the key length is more than 128 bits. The default key
5415 length in SILC is now 256 bits.
5417 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5418 to indicate unsupported algorithm.
5420 * Renamed rijndael.c to aes.c and all functions as well.
5422 * Fixed a long standing channel key setting bug in client library.
5423 Weird that it has never surfaced before.
5425 * Fixed bug in channel deletion. If the entire channel is removed
5426 then it must also delete the references of the channel entry
5427 from the client's channel list as the client's channel entry and
5428 the channel's client entry share same memory.
5430 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Implemented CONNECT and SHUTDOWN commands in the client.
5434 * Implemented CLOSE command to the client.
5436 * Added the function silc_idlist_find_server_by_name into the
5437 files silcd/idlist.[ch].
5439 Added the function silc_idlist_find_server_by_conn into the
5440 files silcd/idlist.[ch].
5442 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * DIE command was renamed to SHUTDOWN. Updated the both code
5447 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5448 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5450 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5453 * Added function silc_server_create_connection function to create
5454 connection to remote router. My server implementation actually
5455 does not allow router to connect to normal server (it expects
5456 that normal server always initiates the connection to the router)
5457 so the CONNECT command is only good for connecting to another
5460 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5463 or some other client was kicked from the channel.
5465 Implemented the handling of the notify type to both client
5468 Implemented silc_server_send_notify_kicked to send the KICKED
5469 notify. It is used to send it to the server's primary router.
5471 * Implemented the KICK command into server and client.
5473 * Added `query' argument to the silc_idlist_get_client function
5474 to indicate whether to query the client from server or not if
5477 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5478 to indicate that the client is not channel founder.
5482 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Removed the rng context from SilcPacketContext structure and
5485 changed that the packet routine uses the Global RNG API.
5487 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Added support for quit message that client can "leave" on the
5490 channel when it quits the SILC. It is ditributed inside the
5491 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5493 Added silc_server_free_client_data that will take the
5494 signoff message as argument.
5496 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5498 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Updated parts of the protocol specification to keep it up
5503 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5506 payloads in one packet.
5508 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5509 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5510 use now the new List flag.
5512 * Also deprecated the following packet types: REPLACE_ID,
5513 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5515 * Added list support for Notify packet in server.
5517 * Added silc_server_send_notify_channel_change to send the
5518 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5519 the silc_server_send_replace_id.
5521 * Added silc_server_send_notify_nick_change to send the
5522 NICK_CHANGE notify type. Deprecates the function
5523 silc_server_send_replace_id.
5525 * Added silc_server_send_notify_join to send the JOIN notify type.
5526 Deprecates the function silc_server_send_new_channel_user.
5528 * Added silc_server_send_notify_leave to send LEAVE notify type.
5529 Deprecates the function silc_server_send_remove_channel_user.
5531 * Added silc_server_send_notify_cmode and
5532 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5533 types. Deprecates the silc_server_send_set_mode function.
5535 * Added SERVER_SIGNOFF notify type to indicate that server has
5536 quit. This means that all clients on the channel from that
5537 server will drop. This can be also used when netsplit happens.
5539 Deprecated REMOVE_ID packet type since it is not needed anymore
5542 Added silc_server_send_notify_server_signoff to send the
5543 SERVER_SIGNOFF notify type. Deprecates the function
5544 silc_server_send_remove_id.
5546 Added also silc_server_send_notify_signoff to send the
5547 SIGNOFF notify type.
5549 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5550 SILC protocol from this day on. Changed the protocol
5551 specification as well.
5553 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5554 notify type. It is used between routers to notify about
5555 topic changes on a channel.
5557 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5560 * Partly updated the protocol specification to comply with the
5561 changes now made. It is still though a bit outdated.
5563 * The JOIN notify type now takes one extra argument <Channel ID>.
5564 The packet used to be destined to the channel but now the
5565 JOIN type may be sent as list thus it is impossible to
5566 destine it to any specific channel. By adding this argument
5567 it is again possible.
5569 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Added CREDITS file. The CHANGES and CREDITS file will appear
5572 in the distribution as well.
5574 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5577 types in the server's silcd/packet_receive.c.
5579 * Implemented CMODE and CUMODE to work in router environment.
5581 * Fixed minor encoding and decoding buglet from the
5582 lib/silccore/silcmode.c.
5584 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5587 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5589 * Changed all SilcConfigServer* and silc_config_server* to
5590 SilcServerConfig* and silc_server_config*, respectively.
5593 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Associated the ID (client or server ID) to the Authentication
5596 Payload to avoid any possibility of forging. Updated the
5597 protocol specification and the code accordingly.
5599 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * The RSA key length is now save to the RsaKey context in the
5602 key generation process in lib/silccrypt/rsa.c. The key length
5603 is now used to figure out the maximum size of the block allowed
5604 to be encrypted/signed.
5606 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5607 is equivalent to the silc_mp_mp2bin but does not allocate any
5610 * Changed silc_mp_mp2bin API to take length argument. If it is
5611 non-zero then the buffer is allocated that large. If zero, then
5612 the size is approximated using silc_mp_sizeinbase, which however
5615 * Created Global RNG API which is global RNG that application can
5616 initialize. After initializing, any routine anywhere in the
5617 code (including library) can use RNG without allocating a new
5618 RNG object. This was done to allow this sort of use of the
5619 RNG in code that has no chance to allocate RNG object. All
5620 applications currently allocate this and many routines in the
5621 library use this. Affected file lib/silccrypt/silcrng.[ch].
5623 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5624 it to use the Global RNG API.
5626 * Defined Authentication Payload into protocol specification that
5627 is used during SILC session to authenticate entities. It is
5628 used for example by client to authenticate itself to the server
5629 to obtain server operator privileges.
5631 Implemented this payload into the lib/silccore/silcauth.[ch].
5632 Implemented also routines for public key based authentication
5633 as the new protocol specification dictates.
5635 Moved definitions of different authentication methods from
5636 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5638 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5639 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5640 silc_pkcs_verify_with_hash functions into the file
5641 lib/silccrypt/silcpkcs.[ch].
5643 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * The client entry's userinfo pointer must be always valid.
5646 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5647 will fail since it requires the userinfo. Now, the userinfo
5648 is allocated as "" if actual userinfo does not exist. Actually,
5649 it must exist and it is totally Ok to drop client connections
5650 that does not announce the userinfo. However, we will make
5651 this workaround for now.
5653 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5654 to return the remote port by socket.
5656 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5659 SILC_SERVER_PENDING_EXEC and added an new macro
5660 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5661 data or when error occurs while processing the pending command.
5663 Added new argument `destructor' into silc_server_command_pending
5664 and to the SilcServerCommandPending object. This destructor is
5665 now called after calling the pending callback or if error occurs
5666 immediately. If error occurs the actual pending callback won't
5667 be called at all - only the destructor. The destructor may be
5668 NULL if destructor is not needed.
5670 All this applies for client library code as well. Similar
5671 changes were made there as well for the pending commands.
5673 In the client, the application must now allocate the
5674 SilcClientCommandContext with the silc_client_command_alloc
5677 * Added reference counter to the SilcServerCommandContext. Added
5678 function silc_server_command_alloc and silc_server_command_dup
5681 Same type of functions added to the client library for the same
5684 * Removed the cmd_ident from IDListData away since it is now
5685 global for all connections. It is the command identifier used
5686 in command sending and with pending commands. The affected file
5689 * Added reference counter to the SilcSocketConnection objecet to
5690 indicate the usage count of the object. The object won't be
5691 freed untill the reference counter hits zero. Currently only
5692 server uses this, and client ignores it. The client must be
5693 set to use this too later. The affected files are
5694 lib/silccore/silcsockconn.[ch]. Added also the function
5695 silc_socket_dup to increase the reference counter.
5697 This was mainly added because it is possible that the socket
5698 is removed underneath of pending command or other async
5699 operation. Now it won't be free'd and proper DISCONNECTING
5700 flags, etc. can be set to avoid sending data to connection that
5701 is not valid anymore.
5703 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5704 the connection. After that it sets SILC_SET_DISCONNECTED.
5705 It is, however, possible that the socket data is not still freed.
5706 The silc_server_packet_process now checks that data is not
5707 read or written to connection that is DISCONNECTED. The socket
5708 get's freed when the reference counter hits zero.
5710 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Changed the client operation API: channel_message operation's
5713 `sender' is now the client entry of the sender, not the nickname
5714 and the `channel' is the channel entry, not the channel name.
5716 In the private_message operation the `sender' is now also the
5717 client entry of the sender not the nickname.
5719 Affected file is lib/silcclient/ops.h and all applications
5720 using the client operations.
5722 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Moved the calling of ops->connect() from connect_to_server_final
5725 into receive_new_id functin since that is the point when the
5726 client is actually allowed to send traffic to network. The
5727 affected file is lib/silcclient/client.c.
5729 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5732 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5733 (if needs broadcasting) instead of broadcasting the packets one
5734 by one which would make a burst in the network traffic.
5736 * Added `broadcast' argument to the functions in silcd/server.[ch]
5737 silc_server_create_new_channel[_with_id] to indicate whether
5738 to send New Channel packet to primary router.
5740 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Added new function into the silcd/server.[ch] files:
5743 silc_server_create_new_channel_with_id to create new channel with
5744 already existing Channel ID.
5746 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5747 lib/silccore/silcpacket.h. This packet is used t send list of
5748 Set Mode payloads inside one packet. Server uses this to set
5749 the modes for the channels and clients on those channels, that it
5750 announced to the router when it connected to it. The protocol
5751 specification has been updated accordingly.
5753 * The silc_server_new_channel did not handle the packet coming
5754 from normal server as it normally does not send that. However,
5755 when it announces its channels it does send it. Implemented
5756 the support for that.
5758 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5759 into the file lib/silccore/id.h.
5761 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Fixed memory leaks in the functions silc_idlist_del_client,
5764 silc_idlist_del_channel and silc_idlist_del_server in the file
5765 silcd/idlist.c. All of those leaked like a sieve.
5767 * Fixed some small memory leaks in the client's function
5768 silc_client_notify_by_server.
5770 * Added functions into silcd/server.c: silc_server_announce_clients,
5771 silc_server_announce_channels and silc_server_announce_server.
5772 These functions are used by normal and router server to announce
5773 to its primary router about clients, channels and servers (when
5774 router) that we own. This is done after we've connected to the
5777 These functions effectively implements the following packet types:
5778 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5779 and SILC_PACKET_NEW_ID_LIST.
5781 * Added new functions into the silcd/packet_receive.[ch]:
5782 silc_server_new_id_list, silc_server_new_channel_list and
5783 silc_server_new_channel_user_list to handle the incoming
5784 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5786 * Added support of changing Channel ID in the function
5787 silc_server_replace_id. If the server that announces a channel
5788 to the router already exists in the router (with same name but
5789 with different Channel ID), router is responsible to send
5790 Replace ID packet to the server and force the server to change
5791 the Channel ID to the one router has.
5793 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5794 client that the Channel ID has been changed by the router. The
5795 normal server sends this to the client. Client must start using
5796 the new Channel ID as the channel's ID.
5798 Implemented handling of this new type into lib/silcclient/client.c
5799 into the function silc_client_notify_by_server.
5801 * Added new function silc_idlist_replace_channel_id into the files
5802 silcd/idlist.[ch] to replace the Channel ID.
5804 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Call silc_server_command_identify_check always when processing
5807 the IDENTIFY command in silcd/command.c
5809 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5812 send keepalive packets. The packet can be sent by clients,
5813 servers and routers.
5815 Added function silc_socket_set_heartbeat into the file
5816 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5817 If not set, the heartbeat is not performed. The actual
5818 heartbeat is implemented in the low level socket connection
5819 library. However, application is responsible of actually
5822 Added silc_server_send_heartbeat to send the actual heartbeat
5823 packet into silcd/packet_send.[ch]. Server now performs
5824 keepalive with all connections.
5826 * Added silc_task_get_first function into lib/silcutil/silctask.c
5827 to return the timeout task with shortest timeout. There was a bug
5828 in task unregistration that caused problems. TODO has been
5829 updated to include that task system must be rewritten.
5831 * The client library will now resolve the client information when
5832 receiving JOIN notify from server for client that we know but
5833 have incomplete information.
5835 * Rewrote parts of silc_server_remove_from_channels and
5836 silc_server_remove_from_one_channel as they did not remove the
5837 channel in some circumstances even though they should've.
5839 * Encryption problem encountered in server:
5841 The LEAVE command used to send the Channel Key packet to the
5842 router immediately after generating it. However, the code
5843 had earlier sent Remove Channel user packet but not immediately,
5844 ie. it was put to queue. The order of packets in the router
5845 was that Channel Key packet was first and Remove Channel User
5846 packet was second, even though they were encrypted in the
5847 reverse order. For this reason, MAC check failed. Now, this
5848 is fixed by not sending the Channel Key packet immediately but
5849 putting it to queue. However, this is more fundamental problem:
5850 packets that are in queue should actually not be encrypted
5851 because packets that are sent immediately gets encrypted
5852 actually with wrong IV (and thus MAC check fails). So, packets
5853 that are in queue should be encrypted when they are sent to
5854 the wire and not when they put to the queue.
5856 However, the problem is that the current system has not been
5857 designed to work that way. Instead, the packet is encrypted
5858 as soon as possible and left to the queue. The queue is then
5859 just purged into wire. There won't be any fixes for this
5860 any time soon. So, the current semantic for packet sending
5863 o If you send packet to remote host and do not force the send
5864 (the packet will be in queue) then all subsequent packets to the
5865 same remote host must also be put to the queue. Only after the
5866 queue has been purged is it safe again to force the packet
5869 o If you send all packets immediately then it safe to send
5870 any of subsequent packets through the queue, however, after
5871 the first packet is put to queue then any subsequent packets
5872 must also be put to the queue.
5874 Follow these rules and everything works fine.
5876 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Added new function silc_server_remove_clients_by_server to
5879 remove all client entries from ID list when the server connection
5880 is lost. In this case it is also important to invalidate all
5881 client entires as they hold the invalid server entry. This
5882 fixes fatal bug when server has lost connection and will reconnect
5885 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Made some sanity checks to silc_server_daemonise like to check
5888 whether the requested user and group actually exists.
5890 * Added sanity check to SKE's silc_ske_responder_finish to check
5891 that the public and private key actually is valid.
5893 * Invalidate the client's nickname when receiving Replace ID
5894 packet and the Client ID is being replaced. This means that the
5895 server will query the nickname if someone needs it (client)
5898 * Sort the ID Cache in client library when the ID Cache data
5899 has changed (needs sorting).
5901 * Do not allow for SILC client to create several connections to
5902 several servers. The client does not support windows right now
5903 and generating multiple connections causes weird behaviour.
5905 Irssi-silc client does support windows and can handle several
5906 connections without problems, see: www.irssi.org and SILC plugin.
5908 * Fixed some places where client was added to the IDList. The
5909 rule of thumb is following (in order to get everything right):
5910 If the client is directly connected local client then the
5911 `connection' argument must be set and `router' argument must be
5912 NULL to silc_idlist_add_client function. If the client is not
5913 directly connected client then the `router' argument must
5914 bet set and the `connection' argument must be NULL to the
5915 silc_idlist_add_client function.
5917 * The funtion silc_server_packet_send_local_channel actually did
5918 not check whether the client was locally connected or not. It
5919 does that now. Fixed a bug related to LEAVE command.
5921 * Fixed Remove Channel User payload parsing bug in server's
5922 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5924 * The server's silc_server_save_channel_key now checks also the
5925 global ID list for the channel as it might not be in the local
5926 list. Fixed a bug related to LEAVE command.
5928 * Is this the end of the [<unknown>] buglet that has been lurking
5929 around for a long time? A little for loop fix in server's
5930 silc_server_command_whois_parse that is used by both IDENTIFY
5931 and WHOIS command. At least, this was a clear bug and a cause
5932 of one type of [<unknown>] buglet.
5934 * WHOIS and IDENTIFY commands call the function
5935 silc_server_command_[whois/identify]_check function even if
5936 we are not router server.
5938 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added --with-gmp configuration option. If set the GMP
5941 is always compiled in the SILC source tree. If not set then
5942 it is checked whether the system has the GMP3 installed. If
5943 it has then the GMP won't be compiled (the system's headers
5944 and library is used), if it doesn't have it then the GMP is
5945 compiled in the SILC source tree.
5947 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Changed RSA private exponent generation to what PKCS #1
5950 suggests. We try to find the smallest possible d by doing
5951 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5952 not security fix but optimization.
5954 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added new config entry [Identity] to fork the server and run
5957 it as specific user and group. A patch from Bostik.
5959 * Imported Dotconf configuration library into lib/dotconf.
5960 This will be used to create the SILC configuration files later.
5961 It will appear in the distsribution after this commit.
5963 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * A big code auditing weekend happening. Auditing code for
5966 obvious mistakes, bugs and errors. Also, removing any code
5969 Removed files for being obsolete:
5971 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5972 inline in the file lib/silcutil/silcbuffer.h)
5974 o lib/silcutil/silcbufutil.c (the header has inline versions)
5976 Changed code to fix possible error conditions:
5978 o The buffer formatting routines now check that the destination
5979 buffer really has enough space to add the data. This applies for
5980 both buffer formatting and unformatting
5981 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5982 unformatting was changed to accomodate following rules:
5983 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5984 sent to the function while XXX_*STRING will not allocate or copy
5985 the data into the buffer. Instead it sets the pointer from the
5986 buffer into the pointer sent as argument (XXX_*STRING used to
5987 require that the pointer must be allocated already). This change
5988 makes this whole thing a bit more consistent and more optimized
5989 (note that the data returned in the unformatting with XXX_*STRING
5990 must not be freed now). The routines return now -1 on error.
5992 o Tried to find all code that use buffer_format and buffer_unformat
5993 and added return value checking to prevent formatting and
5994 especially unformatting errors and possible subsequent fatal
5997 o Changed ske->x and ske->KEY to mallocated pointers in
5998 lib/silcske/silcske.h. Fixed possible data and memory leak.
6000 o Added return value checking to all *_parse* functions. Fixed
6001 many memory leaks as well.
6003 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6004 so that buffer overflows would not happen. All code now also
6005 checks the return value as it can fail.
6007 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6009 * Added reconnection support to server if the normal server looses
6010 its connection to the router (for example if router is rebooted).
6011 The server performs normal reconnection strategy implemented
6012 to the server. Affected file silcd/server.c.
6014 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Added new packet type SILC_PACKET_SET_MODE that is used to
6017 distribute the information about changed modes (for clients,
6018 channels and clients channel modes) to all routers in the
6019 network. Updated the protocol specification accordingly.
6021 Added functions into silcd/packet_send.c and
6022 silcd/packet_receive.c: silc_server_send_set_mode,
6023 silc_server_set_mode.
6025 Added new files silcmode.[ch] into lib/silccore that implements
6026 the encoding and decoding of Set Mode Payload. Added new type
6027 SilcSetModePayload. Moved the definitions of different modes
6028 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6030 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Oops, a little mistake in server's connection authentication
6033 protocol. The protocol is not ended with FAILURE but with
6034 SUCCESS if the authentication is Ok. :) Affected file is
6037 * Implemented NICK_CHANGE notify handling in server in the file
6038 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6039 the local clients on the channel. After the changing nickname
6040 in router environment snhould work and the [<unknown>] nickname
6041 should appear no more.
6043 The silc_server_replace_id function that receives the Replace ID
6044 payload now sends the NICK_CHANGE notify type also in the file
6045 silcd/packet_receive.c
6047 * Changed WHOIS and IDENTIFY command to support the maximum amount
6048 of arguments defined in protocol specs (3328 arguments). This
6049 fixed a bug that caused problems when there were more than three
6052 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Added extra parameter, command identifier, to the
6055 silc_client_send_command so that explicit command identifier
6058 Changed that ID list routines uses specific command identifier
6059 when sending WHOIS/IDENTIFY requests to the server so that they
6060 can be identified when the reply comes back.
6062 Affected files lib/silcclient/command.[ch],
6063 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6065 * Added `sender' argument to silc_server_packet_send_to_channel
6066 to indicaet the sender who originally sent the packet to us
6067 that we are now re-sending. Ignored if NULL. Affected file
6068 silcd/packet_send.[ch].
6070 * Added some server statistics support in silcd/server_internal.h
6071 SilcServerStatistics structure and around the server code. Also
6072 send some nice statistics information when client is connecting
6075 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Fixed channel ID decoding in server's JOIN command reply in
6078 silcd/command_reply.c
6080 * Fixed braodcasting of replace ID payload to not to send it if
6081 we are standalone server in silcd/packet_receive.c.
6083 * Fixed all channel message sending routines to not to send
6084 packets to clients that has router set, since they are routed
6085 separately in the same function earlier. Affects file
6086 silcd/packet_send.c and all channel packet sending functions.
6088 * In USERS reply, res_argv[i] are not allocated, the table
6089 is allocated. Thus changed that free the table, not its
6092 * In server's whois_check and identify_check if the client is
6093 locally connected do not send any WHOIS commands - they are not
6096 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Fixed some minor bugs in client when sending WHOIS command. The
6099 arguments was in wrong order.
6101 * Removed statis function add_to_channel from server in
6102 silcd/command.c that was previously used with the joining but
6105 * Tested USERS command in router environment successfully with two
6106 routers, two servers and two clients.
6108 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Reorganized the USERS command and command reply in client library
6111 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6112 When the command is given by user we register a pending command
6113 callback that will reprocess the command after the reply has been
6114 received from the server. When reprocessing the packet we then
6115 display the information. Thus, the USERS information is displayed
6116 now in the command callback instead of in the command reply
6117 callback. The processing of the command is same as previously
6118 when server has sent the command reply in the JOINing process.
6120 * Added to USERS command in silcd/command_reply.c to join the client,
6121 we didn't use to know about, to the channel after we've created
6122 a client entry for it. Also, for clienet we did know already still
6123 check whether it is on the channel or not and add it if not.
6125 * Removed silc_server_command_join_notify as the function and its
6128 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Changed the client's pending command handling to the same as the
6131 server's pending command handling. It is also now possible to
6132 execute command reply functions from other command reply
6133 function as the function callbacks for commands and command
6134 replies are one and same. The pending commands are not static
6135 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6136 in client connection context. Thus, pending commands are server
6137 connection specific as it is convenient.
6139 Changed the function silc_client_command_pending and
6140 silc_client_command_pending_del and added new function
6141 silc_client_command_pending_check. Removed the
6142 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6145 * Added cmd_ident, current command identifier, to the client
6146 connection context in lib/silcclient/client.h to keep track on
6147 command identifiers used in command sending. Client's command reply
6148 function handling now supports the mandatory command identifiers.
6150 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6151 funtions in client to fully support pending command callbacks.
6153 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6154 as one of the arguments to the application in the command reply
6157 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6158 before first releasing SILC but came back. Now it is removed again
6159 and should come back nomore. The FORWARDED flag was used only
6160 by the JOINing procedure by forwarding the command packet to router.
6161 Now, the JOINing procedure has been changed to more generic (due
6162 to various router environment issues) and FORWARDED is not needed
6163 anymore for anything. The protocol specification is yet to be
6166 Now, removed silc_server_packet_forward from server and the flag
6167 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6169 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Renamed NAMES command to USERS command. The NAMES was named that
6172 due to historical reasons. Now it is renamed. Also, rewrote
6173 parts of the USERS command. The nickname list is not sent anymore
6174 by the server. Only Client ID and mode lists are sent in the USERS
6175 command. Changed this also to the protocol specification.
6177 The client now resolves the names and stuff after it receives
6178 the USERS list from the server when joining to the channel.
6180 * WHOIS and IDENTIFY commands has been changed to support multiple
6181 Client ID's per command. One can now search for multiple users
6182 in the network by sending only one WHOIS or IDENTIFY command.
6183 Changed the code and the protocol specifications.
6185 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6186 uses silc_server_command_whois_parse to parse the request. */
6188 * If normal server, do not parse the WHOIS and IDENTIFY requests
6189 before sending it to the router. Saves some time.
6191 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Fixed JOIN command on client library. Wrong number of arguments
6194 used to crash the client.
6196 * Added silc_server_channel_has_global function to check whether
6197 channel has global users or not.
6199 * Added silc_server_channel_has_local function to check whether channel
6200 has locally connected clients on the channel.
6202 * The silc_server_remove_from_one_channel now checks whether the
6203 channel has global users or not after given client was removed from
6204 the channel. It also checks whether the channel has local clients
6205 on the channel anymore. If it does not have then the channel entry
6206 is removed as it is not needed anymore.
6208 * The silc_server_notify now checks on JOIN notify whether the joining
6209 client is one of locally connected or global. If it is global then
6210 the channel has now global users on the channel and that is marked
6211 to the channel entry. Also, it now saves the global client to
6212 global list who is joining and JOINs it to the channel. This is
6213 for normal server, that is.
6215 Changed silc_server_send_notify_on_channel,
6216 silc_server_packet_relay_to_channel and
6217 silc_server_packet_send_to_channel check if we are normal server
6218 and client has router set (ie. global client) do not send the
6219 message to that client, as it is already routed to our router.
6221 * Implemented LEAVE notify type handling in silc_server_notify
6224 * Tested LEAVE command in router environment successfully. Tested
6225 with two routers, two servers and two clients.
6229 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6231 * Implemented SIGNOFF notify type handling in silc_server_notify
6234 * silc_server_remove_id now removes the client entry from all channels
6235 it has joined and thusly sends SIGNOFF notify type.
6237 * Rewrote the NAMES list generation in server by removing two excess
6238 loops. The lists are created now inside one loop.
6240 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * silc_server_remove_channel_user checks now also global list
6243 for channel and client.
6245 * silc_server_new_channel_user checks now both local and global
6246 list for channel and client. Fixed a bug in client id decoding.
6247 Used to decode wrong buffer.
6249 * silc_server_channel_message checks now both local and global
6250 list for channel entry.
6252 * Tested channel joining (hence JOIN) in router environment
6253 successfully. Tested with two routers, two servers and two
6256 * Tested channel message sending in router environment successfully.
6258 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Added silc_server_save_channel_key into server.[ch] to save the
6261 received channel key in Channel Key payload processing. It is
6262 also used in JOIN command reply handling.
6264 Equivalent function silc_client_save_channel_key added into
6265 client.[ch] into client library.
6267 * Changed JOIN command reply to send information whether the channel
6268 was created or not (is existing already) and the channel key
6269 payload. Changed protocol specs accordingly.
6271 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6272 the request was sent by ID and not by nickname. Crashed on
6275 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6278 now correctly save the received data.
6280 * silc_server_free_sock_user_data now notifies routers in the
6281 network about entities leaving the network.
6283 At the same time implemented functions silc_server_remove_id
6284 and silc_server_send_remove_id to receive and send REMOVE_ID
6285 packets. The packet is used to notify routers in the network
6286 about leaving entities. The ID removed will become invalid in
6289 * Added function silc_idlist_del_server into server. Removes and
6290 free's server entry from ID list.
6292 * silc_server_private_message function now checks, if we are router,
6293 that the destination ID really is valid ID, naturally.
6295 * In router when NEW_ID packet is received (for new client) the
6296 hash of the Client ID is saved in the ID Cache but the
6297 client->nickname is set to NULL, instead of putting the hash
6300 IDENTIFY command now also checks that client->nickname must be
6301 valid. If it is not if will request the data from the server who
6302 owns the client. Added new function
6303 silc_server_command_identify_check.
6305 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6306 to set the command to already allocated Command Payload.
6308 * Tested private message sending in router environment with two
6309 routers, two servers and two clients. Fixed minor bugs and now
6312 * Fixed segfault from client's NAMES command. Used to crash if
6315 * Forwarded packets must not be routed even if it is not destined
6316 to the receiver. Changed server code comply with this.
6318 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6320 * Added `require_reverse_mapping' boolean value to ServerParams
6321 structure. If TRUE (not default) the server will require that
6322 the connecting host has fully qualified domain name.
6324 If the reverse mapping is not required and hostname could not be
6325 found the IP address is used as hostname.
6327 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Implemented version string checking to both client and server.
6330 The check is incomplete currently due to the abnormal version
6331 strings used in development version of SILC.
6333 * Changed all command functions in server to use the new
6336 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Changed char *data to unsigned char *data in ID Cache system to
6339 support binary data as ID Cache data. Changed code to support
6340 binary data in lib/silccore/idcache.c.
6342 * Renamed silc_server_packet_relay_command_reply to
6343 silc_server_command_reply as it is normal packet receiving
6344 function. Rewrote the function to accept command replys for
6345 servers and not only for clients.
6347 * Mark remote router always as registered server if we are connecting
6348 to it. Otherwise, commands sent by the router to us are ignored.
6350 * All ID List find routines now returns the ID Cache Entry pointer
6351 as well if requested.
6353 * WHOIS command works now in router environment, tested with two
6354 routers, two servers and two clients.
6356 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6357 in router environment (as it is almost equivalent to WHOIS) but
6358 hasn't been tested thoroughly. Added new functions:
6360 silc_server_command_identify_parse
6361 silc_server_command_identify_send_reply
6362 silc_server_command_identify_from_client
6363 silc_server_command_identify_from_server
6365 * Disabled route cache adding because adding two different ID's with
6366 same IP replaces the old cache entry thus giving wrong route.
6367 The entry->router->connection is always the fastest route anyway
6368 so route cache may not be needed. Of course, new routes maybe
6369 established after receiving the ID when the entry->router->connection
6370 might not be anymore the most optimal.
6372 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Add route cache for received ID for fast routing.
6376 * Added silc_server_packet_route to route received packet on router
6377 that is not destined to us.
6379 * Renamed silc_server_get_route to silc_server_route_get.
6381 * Added id_string and id_string_len fields into SilcServer to
6382 include encoded ServerID for fast comparing without excess
6383 encoding of the ID's.
6385 * Cleaned up WHOIS command on server side. Added following static
6388 silc_server_command_whois_parse
6389 silc_server_command_whois_check
6390 silc_server_command_whois_send_reply
6391 silc_server_command_whois_from_client
6392 silc_server_command_whois_from_server
6394 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6395 arguments in command replies. All command functions should be
6396 updated to use this macro.
6398 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Minor typo fixes on command reply handling on server.
6402 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Added silc_server_command_add_to_channel internal routine to add
6405 the client to the channel after router has created the channel and
6406 sent command reply to the server.
6408 * Added generic silc_server_send_command to send any command from
6411 * Use static buffer with ID rendering instead of duplicating data.
6413 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6415 * Fixed a channel user mode bug when joining to a channel server gave
6416 everybody channel founder rights, oops.
6418 * We mark ourselves as the router of the incoming server connection
6419 if we are router ourselves. This way we can check in some packet
6420 sending functions whether it is locally connected server. For
6421 incoming router connections we put NULL.
6423 * For router sending packets locally means now always sending the
6424 packet cell wide; to local clients and local servers. For normal
6425 server sending packet locally means sending it to only local
6428 * Fixed the JOIN command to really work in router environment. If the
6429 channel is created it is always created by the router. Router is
6430 also responsible of making the initial joining to the channel,
6431 sending JOIN notify to the sending server and distributing
6432 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6433 does not exist server doesn't do anything else but forward the
6434 command to the router which performs everything.
6436 * Added silc_server_send_channel_key function to send the Channel Key
6439 * Added silc_server_create_channel_key to create new channel key. The
6440 channel key is now re-generated everytime someone joins or leaves
6441 a channel, as protocol dictates. Note: channel->key_len is the
6444 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6447 packet_receive.[ch] to separate packet sending and receiving
6448 routines. The server.[ch] now includes everything else including
6449 actual packet processing (writing and reading data) and other
6452 Renamed silc_server_private_message_send_internal to
6453 silc_server_send_private_message. The routine is still though
6454 used only to relay private messages as server does not send
6455 private messages itself.
6457 Renamed silc_server_new_channel to silc_server_create_new_channel
6458 and added new function sicl_server_new_channel that handles the
6459 incoming New Channel packet. Added also new sending function
6460 silc_server_send_new_channel to send New Channel Payload.
6462 * Added new function silc_server_notify to process incoming notify
6463 packet to the server/router. Server may then relay the notify
6464 to clients if needed.
6466 * Added new function silc_server_new_channel_user to process incoming
6467 New Channel User packet. Router will redistribute the packet and
6468 send JOIN notify to its local clients and locally connected servers
6469 if needed. Normal server will send JOIN notify to its local client
6470 on same channel when received this packet. Added also corresponding
6471 sending function silc_server_send_new_channel_user to sent the
6474 * Added boolean route argument to send_notif_to_channel and
6475 packet_send_to_channel functions to attempt to route the packet
6476 if it is TRUE and send only locally if it is FALSE.
6478 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6480 * silc_server_replace_id now broadcasts the received replace ID
6481 packet if it is not broadcast packet already. The router must
6482 broadcast to inform other routers about changed ID.
6484 * Added backpointer to server's router into SilcServer context in
6485 silcd/server_internal.h.
6487 * Fixed silc_server_packet_broadcast to send correct broadcast
6490 * The channel key is now distributed to the local client as soon
6491 as it is received from the router (in router environment) so that
6492 no other packet may be sent for the channel until client has
6495 * silc_server_remove_channel_user now broadcasts the received
6496 Remove Channel User packet if it is not broadcast packet already.
6497 The router must broadcast to inform other routers about removed
6500 * Added users field into SilcPacketContext that is a reference count
6501 of the context. One can increase the reference count by calling
6502 silc_packet_context_dup which is now changed to just increase the
6503 reference count instead of duplicating the data. The reference
6504 count is decresed by calling silc_packet_context_free that will
6505 free the data after the reference count hits zero.
6507 For now on the packet context and everything allocated into it
6508 (including the raw packet from network) must be freed by calling
6509 the new silc_packet_context_free function. Added also new function
6510 silc_packet_context_alloc that must be used now to allocate the
6511 context. This also means that if a routine is asynchronous from
6512 silc_[client/server]_packet_parse_type the packet context must
6513 be duplicated by calling silc_packet_context_dup. Otherwise it
6514 gets free'd after silc_[client/server]_packet_parse_type returns.
6515 Also, one must remember that if packet is duplicated then its
6516 reference count must be decresed by calling the free function as
6517 many times as it was duplicated.
6519 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6520 from both client and server.
6522 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * Made joining to a channel working in router environment.
6526 * Cleaned up JOIN command on server side and create function
6527 silc_server_command_join_channel internal routine to make the
6530 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Changed silc_command_pending list to SilcDList. Also, added
6533 `ident' field to SilcServerCommandPending structure to identify
6534 the reply and to call correct callback.
6536 Added silc_server_command_pending_check function to replace the
6537 corresnponding macro. The silc_command_pending list is not
6540 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6541 to set identifier to previously allocated Command Payload. It
6542 is used to set identifier for command when resending Command
6545 * Added silc_command_payload_encode_payload to encode Command
6546 Payload buffer from SilcCommandPayload structure.
6548 * Added silc_argument_payload_encode_payload to encode Argument
6549 payload buffer from SilcArgumentPayload structure.
6551 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * Changed WHOIS command to support router connection on server side.
6554 The whois request is always sent to router unless the server is
6555 standalone server. After server has received the reply from the
6556 router will it send the reply to the client.
6558 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6559 broadcast received broadcast packet. The function is used only
6560 by router. The broadcast packet is always sent to the router's
6563 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6564 render given ID to printable string, for log files for example.
6566 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Made basic router to router connections working. At least they
6569 can now connect to each other but nothing really works the way
6570 they are supposed - yet.
6572 * Added new initiator token to RouterConnection configuration
6573 file in silcd/serverconfig.[ch]. It is used to tell whether we
6574 are the initiator to the remote router or whether we'll expect
6575 the other end to connect.
6577 * Moved registering of listener task to silc_server_init, hence
6578 the server starts listenning as soon as it is run, even if it
6579 does not have connections to other routers. Let's see how well
6582 * Changed default connection retry timeouts for more suitable in
6585 * Removed cipher and such arguments from silc_idlist_add_client
6586 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6587 Added new function silc_idlist_add_data to add the keys and stuff
6590 * Added SilcIDListData structure and added it to SilcClientEntry
6591 and SilcServerEntry as their first field in the structure. This
6592 way we can explicitly cast the ID entries to the SilcIDListData
6593 structure and get common data for the entries. In past, we had
6594 to first check what type of connection it is and then cast it to
6595 correct ID entry type. Now, we can directly cast the opaque
6596 pointer to the SilcIDListData (no matter what ID entry it actually
6597 is) and get the data needed.
6599 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6602 in some circumstances even if threre were timeout tasks, though not
6603 IO tasks, but tasks anyway. Now fixed.
6605 * Defined SilcServerConnection structure to hold connection specific
6606 stuff about directly connected servers and routers. The definition
6607 is currently in silcd/server_internal.h. I thought about having
6608 a bit more important role fro this struct but for now it is used
6609 only when connecting to other server (or router actually).
6611 * Added connecting retry support in server when connecting to
6612 router(s). The retry feature implement exponential backoff
6613 algorithm. Also, added SilcServerParams structure to hold default
6614 parameters for server. For now, it include these retry settings
6615 and are hard coded. After server is moded to be as Silc Server
6616 Library this structure will be more important.
6618 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Changed client librarys channel->clients table to SilcList and
6621 changed code accordingly.
6623 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6625 * Changed client's channel table to SilcList and changed code
6626 accordingly. Also changed SilcChannelClientEntry to include back-
6627 pointer to the channel so that client entry can use that structure
6628 as list as well and we have fast cross-reference to the channel.
6629 This change dramatically decreased the complexity of channel
6630 handling with client entry and vice versa (removed one extra
6631 loop when searching for channel entry from many functions).
6633 * Changed server->sim from table to SilcDList and changed code
6636 * NAMES command can now be used from user interface. It will show
6637 the user list on the channel, neatly.
6639 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6640 Code now saves realname of the user if it becomes available.
6642 * Renamed configure.in to configure.in.pre and made ./prepare
6643 script to automatically add correct version string to
6644 configure.in which it creates from configure.in.pre.
6646 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * NAMES command reply now shows users mode with the nickname when
6651 * Moved silc_client_ch[u]mode[_char] functions from
6652 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6653 place sucks, they are utility functions and should be in some
6656 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6658 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6661 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Added TRQ (efficient deque and list library) into lib/trq. This is
6666 a very good list library that is currently used in the SILC. Defined
6667 SilcList API over the library because I didn't like the API very
6668 much. See lib/trq/silclist.h for the API and examples of how to
6669 use the API. Fixed various places in the code to use the new
6670 SilcList API. The SilcList is meant for lists that has a structure
6671 already defined as a list. It is not suitable to add just some
6672 context to the list (in TRQ, the context is the list actually).
6674 So, I defined SilcDList that can be used for the purpose where
6675 predefined list structure does not exit. This can be used as
6676 such list. Now some context just can be added to the SilcDList.
6677 Currently this list is not used in the SILC just yet, though there
6678 are a lot places where this can replace dynamically allocated
6679 tables and I will fix these places, later, to use SilcDList.
6680 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6681 and use TRQ internally).
6683 Also fixed some annoying warning messages that the original TRQ
6684 code generated. Also minor changes to TRQ's Makefile.in.
6686 * Added support for querying by Client ID to both WHOIS and
6687 IDENTIFY commands into server, as required by the protocol.
6689 * Removed method function pointers from SilcBuffer structure. They
6690 weren't used to anything and just increased the context size for
6691 no good reason. This change also made silc_buffer_alloc and
6692 silc_buffer_free functions inline functions.
6694 * Disabled command flooding detection support until it's fixed so
6695 that it accepts commands in but does not execute them more than once
6698 * Added silc_net_localhost(), to return local hostname, into
6699 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6700 that must be initialized before calling silc_client_init.
6702 * Added new function: silc_server_send_notify_on_channels to send
6703 notify messages to all channels client has joined. It is assured
6704 that the message is sent only once per client.
6706 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6707 lib/silcutil/silcutil.[ch] as silc_format function. The new
6708 function is generic and is used by server as well, not only by
6709 the logging routines.
6711 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6712 the provided version string was not acceptable. Added new function:
6713 silc_ske_check_version into lib/silcske/silcske.h. The function
6714 must be implemented by the application (client or server) and it
6715 does not reside in the SKE library. The function checks the version
6716 string remote end sent.
6718 * Added back pointers (to opaque context and to SilcSocketConnection)
6719 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6721 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6722 duplicate packet context structure.
6724 * Changed `notify' client operation to send same arguments as client
6725 receives from server except for ID's. ID's are mapped to correct
6726 ID entry and that is returned. Also, if channel entry is not sent
6727 by server but the notify is for channel the channel entry is sent
6728 to application (otherwise application doesn't know that it is for
6729 channel (library gets it from packet's Destination ID)).
6731 * Added silc_client_remove_from_channels into client library to
6732 remove a client from all channels it has joined to. Used when
6733 received SIGNOFF notify from server. Added also new function
6734 silc_client_replace_from_channels to replace old ID entry with
6735 new ID entry on all channels. Used when received NICK_CHANGE
6738 * Fixed ID Cache list handling in silc_idlist_get_client in
6739 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6740 to get (or query) client by ID.
6742 * Updated TODO list.
6744 * Added connection authentication status message defined by the
6745 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6746 support for these into the code in client and server side.
6748 * Added generic function silc_client_send_command to send any command
6749 with variable argument list. Application should use this function
6750 to send commands if the command functions provided by the library
6751 does not suite for the application's user interface needs.
6753 * Added new `failure' client operation. Application is notified about
6754 received failure packet if client is executing a protocol. In this
6755 case the protocol's execution has failed.
6757 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6758 is required by the protocol.
6760 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6761 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6764 * Added status flag to SilcSKE object to indicate realtime status
6765 of the SKE protocol.
6767 * Application receives now exactly same command reply arguments as
6768 the library receives from server. However, if ID is received the
6769 corresponding ID entry is returned to the application (eg. Client
6770 ID is mapped to correct SilcClientEntry entry and that is returned).
6771 Changed command_reply client operation due to this change.
6773 * Changed all ID's in commands and in command replys as ID Payloads.
6774 Change affected both client and server side codes.
6776 All ID's sent in SILC network (with execption of ID's in SILC
6777 Packet header) are sent in ID Payload to support variable length
6780 * Server now notifies nick changes and notifies all clients on
6781 the channels about the new nickname (about the new Client ID,
6784 * Implemented CMODE command to change channel modes. Supports all
6785 channel modes defined by the protocol specs except ban and invite
6786 lists. (Also, private channel key mode is supported but support for
6787 setting private channel key in client is missing, thus, this mode
6788 has no effect on client side (except that server requires that the
6789 client uses private channel key and normal channel traffic does not
6792 Also, invite mode works per se, but INVITE command does not work
6793 yet correctly, so you can set channel as invite only channel but
6794 inviting clients to the channel does not work (it is yet to be
6795 thought what's the best way to do it).
6797 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6798 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6799 Implemented CUMODE command to change user's mode on the channel.
6800 Supports all modes defined by the protocol specs.
6802 * Added NAMES command reply to return users modes on the channel.
6804 * Removed unnecessary and slow ciphers from lib/silccrypt.
6806 * Set SO_KEEPALIVE option to connection sockets by default.
6808 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6810 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6811 redefined the Notify Payload into protocol specs.
6813 * Added silc_id_payload_parse_id to get ID directly from raw
6816 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6819 accept searching by Client ID as well.
6821 * Added support for LEAVE and SIGNOFF notify types in client library.
6823 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6824 to parse ID Payload from raw data.
6826 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added flags parameter into silc_ske_assemble_security_properties
6829 function in lib/silcske/silcske.[ch].
6831 * Changed notify client operation to fit better for notify messages
6832 sent by server. The notify payload received from server is now
6833 passed to the application (after parsing it to SilcNotifyPayload).
6834 It is application's responsibility to retrieve the arguments
6835 from the payload and show the message the way it wants. The message
6836 sent by server is implementation specific.
6838 * Changed public keys to comply with the protocol specification.
6839 Old public keys are not supported anymore and are not compatible.
6841 * Removed nickname from Channel Payload as the latest draft removed
6842 it. The client must resolve the nickname from the NAMES command
6843 reply received when it joined the channel.
6845 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6847 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Fixed some errors in protocol specification drafts.
6851 * Created lib/silccore/silcnotify.c to implement Notify Payload
6852 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6853 generic payloads described by protocol specifications. The file
6854 includes implementations for ID Payload and Argument Payload.
6856 * Changed Command Payload implementation to use the new Argument
6857 Payload. Changed command_xxxx_payload to command_payload_xxxx
6858 to comply with SILC coding conventions.
6860 * Added suppport for Argument Payload handling in Notify Payload
6861 implementation as protocol requires it. Added the new support
6862 into server and client lib as well.
6864 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Added support for multiple nicknames on same channel. [n] is
6867 added locally to the nickname if there are more than one same
6868 nicknames on the channel.
6870 * Server now sends all nicknames that matched WHOIS request.
6871 Client also shows the list received from server.
6873 * Added TOPIC command to client side. User can now set and show
6874 current topic on channel.
6876 * Added MOTD command to client and server. Also, server sends the
6877 motd when client connects to the server.
6879 * Changed version strings to comply ISO 8601.
6881 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Fixed protocol error handling in client library. It should now
6884 cope even if the SKE fails for some reason.
6886 * Made new protocol specification drafts for submitting to IETF.
6888 * Implemented TOPIC command to server in silcd/command.c.
6890 * Added two new notify types into lib/silccore/silcnotify.h:
6891 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6892 notify nickname change and topic setting/change on a channel.
6894 * API change of command_reply operation in client library. The
6895 application gets now the status type received from server as well.
6897 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6901 * Cras fixed and optimized the packet handling even further and
6902 it should work now. Minor change to the prototype of function
6903 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6905 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6907 * Added new function into lib/silcutil/silcschedule.[ch]:
6908 silc_schedule_with_fd to select() a specified fd. The function
6909 returns after timeout expires or data arrives or goes. The
6910 function is used by packet routines to wait that all data is
6911 received from network.
6913 * Fixed data reading from network in lib/silccore/silcpacket.c.
6914 The code now assures that all data is read from the fd and then
6915 continues packet processing. This was a bug fix since the code
6916 used to drop some data in some circumstances.
6918 * Added new function into lib/silcclient/client.[ch]:
6919 silc_client_start_key_exchange to start key exchange after
6920 connection has been established to server. The code internally
6921 now uses this funtion but its main purpose was to provide it
6922 for applications that perform their own connecting. After
6923 application has created a connection it merely calls this
6924 function to start the key exchange between client and server.
6925 The library takes care of everything else after that.
6927 Updated also lib/silcclient/README to explain the usage of
6930 * Do not send to application information that connection has
6931 been established. Application gets notified it by connect
6934 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Applied cras's patch to add silc_schedule_one function. The
6937 function runs scheduler once and returns.
6939 * Fixed the scheduler after cras messed it up. The timeout
6940 handling works now as it's supposed to work.
6942 * Added into lib/silccore/ silcnotify.h to include notify
6943 message types support. Changed silc_server_send_notify*
6944 functions, in server.[ch], to support those new notify types.
6945 Added the support for the notify types into client library,
6946 as well. Added new notify client operation into ops.h in
6949 * Changed silc_server_packet_send_to_channel to send normal
6950 packets instead of just channel message packets. The function
6951 is now used to send the notify packets to channels. It is not
6952 used to send channel message packets anymore, as server never
6955 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6956 va_arg()s as it seems to require it nowadays. I guess, if SILC
6957 is compiled with older va_arg() the new code should work anyway.
6959 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6961 * Splitted core library. Core library (lib/silccore) includes
6962 now only SILC protocol specific core (and common) components.
6963 Created new utility library (lib/silcutil) that includes more
6964 generic purpose stuff. The stuff for util library was taken
6965 from the old core library. This was minor and easy split.
6967 * Created SILC Client Library (lib/silcclient) that includes
6968 implementation of the SILC client without user interface. This
6969 was major move from silc/ directory. The code has been changed
6970 so that it is transparent towards the user interface. The
6971 silc/ directory includes now the same user interface as before
6972 and it uses the new client library. Read lib/silcclient/README.
6973 Basicly, the client library performs everything else related
6974 to SILC except user interface handling. Also, configuration
6975 files are considered to be part of user interface and library
6976 does not handle them.
6978 This change also changed a lot of structures, function naming etc.
6979 Most important change was that SilcClientWindow object was
6980 renamed to SilcClientConnection in the client library. Created
6981 also new file lib/silcclient/ops.h. Also added new files
6982 silc/local_command.[ch] and silc/client_ops.[ch].
6984 All these changes were made to make it easier for user interface
6985 designers to create what ever user interface for the SILC client
6988 It is also expected that the server will be moved to lib
6989 directory as well and SILC Server Library will be created;
6990 sometimes in the future.
6992 * Removed Local commands from lib/silccore/silccommand.h as
6993 they are application specific and new client library does not
6994 handle any of those anymore.
6996 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6997 old client implementation in silc/.
6999 * Added support for callback functions in SILC_LOG_* macros.
7000 Application can now set its own callbacks that will be called
7001 instead of using the default functions that will always print
7002 the debug messages to stderr (or stdout). Also, debugging can
7003 now be disabled by setting silc_debug to FALSE and re-enabled by
7004 setting it to TRUE. Note, that logging will still work even
7005 if debugging is disabled.
7007 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7008 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7009 silc_log_reset_debug_callbacks.
7011 * To enable debugging in silc client one must give now -d
7012 option on command line.
7014 * Changed silc_schedule_init to automatically allocate task queues
7015 if they are not allocated before calling it.
7017 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7019 * Added GMP 3.1 into math library.
7021 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7023 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7024 a channel in SILC network. The packet is used by servers and
7025 routers to notify other routers that user has left a channel.
7026 This little feature was missing until now. Added the feature
7027 to protocol specification as well.
7029 Added functions: silc_server_send_remove_channel_user and
7030 silc_server_remove_channel_user into server.[ch].
7032 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7033 lib/silccore/silcpacket.h. However, they are not implemented
7036 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7038 * Fixed joining to a channel and sending channel messages
7039 between server and router. The channel message sending should
7040 now work inside a cell.
7042 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Fixed the private message sending between server and router.
7045 The private message sending should now work inside a cell.
7047 * Added silc_server_replace_id into server.[ch] to replace
7048 existing ID in the SILC network.
7050 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7051 and silc_idlist_replace_server_id into idlist.[ch] in server.
7053 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Fixed the server to server connections. Server can again now
7056 connect to router. Router to router connections probably does
7059 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Added dynamic protocol registering support. Now protocols can
7062 registered and unregistered on the fly. Patch by cras.
7064 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * Added lib/contrib directory to hold routines that some platforms
7067 don't have but are needed by SILC.
7069 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7070 into lin/contrib to provide getopt() and getopt_long() for
7071 those who don't have it.
7073 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Added AWAY command to client. When away message is set and
7076 client receives a private message packet the client automatically
7077 replies to the sender with the away message.
7079 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7080 bug seemed to be the cause of recent problems when compiling
7083 * Added version detection support to SKE protocol specification
7084 and added the new changes to the SKE implementation as well.
7085 There were other minor changes in the SKE protocol as well.
7087 Many changes in lib/silcske/silcske.[ch] and in
7088 lib/silcske/payload.[ch].
7090 * Added ^U functionality, clear input line. Patch from cras.
7092 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Mainly small bugfixes on core library. Fixed some debugging
7095 logging and buffer overflow in silclog.c.
7097 * Updated config.sub and config.guess on the distribution tree.
7099 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Added command lagging support in server. Client may execute
7102 commands now only once in two seconds.
7104 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Optimized packet reception. MAC computation and checking is now
7107 also more optimized. A lot previously duplicated code is now
7108 used as generic by both client and server.
7110 * Fixed key pair generation in clientutil.c
7112 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added into lib/silccore/silcbufutil.[ch] new function;
7115 silc_buffer_realloc.
7117 * Moved generic packet sending/encryption functions to
7118 lib/silccore/silcpacket.[ch] from client and server. Some
7119 rewriting of the functions.
7121 * Moved all generic packet reception/decryption functions to
7122 lib/silccore/silcpacket.[ch] from client and server. The
7123 packet processing is now much cleaner in both client and server.
7124 These were major changes in both client and server.
7126 * Created many common functions in server to do packet sending.
7127 Previously code were duplicated a lot, this has been removed
7130 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Rewrote major parts of the ID cache system. Don't know
7133 whether it is better now or not but at least the API is more
7136 * Major rewrite on ID cache stuff on client because of the ID
7137 cache API changes. Added idlist.c to client.
7139 * Also major rewrite on ID cache stuff on server as well.
7140 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7141 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7142 in hand, instead they are all put into the ID cache system now.
7143 All server_idlist_* routines uses ID cache now instead of
7144 traversing its own lists (those lists does not exist anymore).
7145 SilcIDList though still exists. Also, SilcXXXEntry's are
7148 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Finally made the SKE implementation compliant to the protocol
7151 specification. All mp integers are now binary encoded as
7152 opposed being HEX encoded.
7154 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7157 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7158 functions: silc_[encode/decode]_pem. Also added function
7159 silc_encode_pem_file to PEM encode with newlines ('\n') for
7162 * SILC public keys are now encoded either PEM or binary. Same
7163 option is for private keys as well. By default private keys
7164 are binary encoded and public keys PEM encoded. Silly HEX
7165 encoding were removed.
7167 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7168 function to create fingerprints.
7170 * Fixed a bug in SHA1; does not change the original data anymore.
7172 * Partly implemented INFO command on client and server side.
7173 Fixed CLEAR command. Changes to SERVER command; show current
7174 server(s) when giving command without arguments. Added
7175 VERSION command to client.
7177 * Added check to server that unregistered connections cannot
7178 execute commands (unless it is specificly allowed).
7180 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7182 * Fixed screen refresh.
7184 * Fixed channel joining bug from client. On some circumstances
7185 client tried to join to a channel it had already joined.
7187 * Added public key verification process into client's protocol.c.
7188 The client now verifies the public key from user and saves
7189 it into ~./silc/serverkeys/ directory.
7191 Added into: clientutil.[ch]: silc_client_verify_server_key.
7193 * Changed SKE protocol's silc_ske_initiator_finish function
7194 to accept callback function that verifies the received public
7195 key. Removed old silc_ske_verify_public_key function.
7197 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7200 silc_pkcs_private_key[_data]_set.
7202 * Made the password and public authentication more cleaner in
7203 server's protocol.c.
7205 * Removed historic and obsolete protocol `channel_auth' from
7206 both client and server.
7208 * Removed wrong way of sending command status messages from
7209 server to client in server's command.c. The old way violated
7210 protocol specification.
7212 Changes to silccore/silccommand.[ch]: removed
7213 silc_command_encode_status_payload -> not needed anymore,
7214 changed silc_command_encode_payload_va to accept extra
7215 argument on variable argument list. The argument type must
7216 now be provided to the function. Also, added new function:
7217 silc_command_encode_reply_payload_va which is same as
7218 normal command_encode_payload_va except command status type
7219 is provided as extra argument.
7221 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Added ~./silc directory handling. The directory includes the
7224 public and private keys for the client.
7226 Added silc_client_check_silc_dir, silc_client_create_identifier
7227 and silc_client_load_keys.
7229 * Implemented SILC protocol compliant public key. Added public
7230 and private key saving to and loading from files.
7232 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7233 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7234 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7235 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7236 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7238 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7239 silc_pkcs_load_[public/private]_key.
7241 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * Added silc_server_get_route (route.[ch]) to get connection
7244 data for the fastest route for given ID.
7246 * Implemented INVITE command on client and server. The command
7247 were re-defined in the SILC Protocol Specification and the
7248 implementation now complies with the specification.
7250 * Implemented PING command on client and server.
7252 * Implemented NAMES command on client and server. The server side
7253 supports currently only normal server not router server yet.
7254 Some changes to NAMES definition in SILC protocol specification.
7256 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Implemented LEAVE command on client and server.
7260 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7261 again. This change was made to the protocol as well. Server
7262 should not violate the protocol specification anymore.
7264 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7267 was tested. SOCKS4 was not but should work anyway.
